Description

The invention relates to a means of cleaning the inner surfaces of various hollow products and is intended for the destruction of arches and lintels from packed bulk material formed in hard-to-reach places of containers or bins, and cleaning the inner surfaces in these places.

A device for cleaning the inner surface of the tank, containing a hollow shaft having a drive for its rotation and connected to the working body, consisting of sequentially arranged links, adjacent of which are interconnected by articulated joints, the axes of which are parallel, with the possibility of formation of all links in the folded the rectilinear position of a single oblong element and the deviation of the links from this position when the shaft rotates, according to the invention is equipped with a pin, fixing the links of the working body in a folded straight position, a support cup located outside the shaft and having a locking pin for the shaft inside the cup, and sliding bearings installed between the support cup and the shaft, while the links of the working body are hollow with the possibility of formation of all links in the folded rectilinear position in a single oblong element a common internal longitudinal cavity for the said pin, which is placed in it with the possibility of extraction from the subsequent return, and the articulation of adjacent the core is located on one side of the working body relative to its longitudinal axis, and in the cross sections of the shaft and the working body, the inner surface of the shaft cavity and the outer surface of the links of the working body are made with profiles that are mutually appropriate in shape and size with the possibility of free passage of the working body along the shaft cavity in both directions: forward and backward and fixing in the cavity for joint rotation with the shaft of the last link of the working body, which is equipped with a limiter longitudinal It is still inside the shaft cavity and is made with a length that ensures the location of its swivel connection with the previous link of the working body outside the shaft cavity (RF patent, 2191078, Shredder-cleaner, Tretyakov G.M., Dudkin E.P., Goryushinsky V.S. ., Goryushinsky I.V., Goryushinsky E.V. IPC B08B 9/08, B65D 88/68, publ. 10/20/2002. Bull. No. 29).

The disadvantage of this known device is the low quality of cleaning inaccessible places on the inner surfaces of various containers, such as containers or bins, and the ineffective destruction of the arches of caked bulk material formed during unloading after prolonged storage in containers or bins.

Known portable demolition-cleaner, containing a hollow drive shaft, two symmetrically located relative to the longitudinal axis of the shaft of the cleaning tool, each of which is connected via an axis at one end to the hollow drive shaft, made in the form of a working body and straps articulated by a hinge, the axis of which perpendicular to the longitudinal axis of the drive shaft, and connected to another cleaning tool by means of an axis passing perpendicular to the longitudinal axis of the drive shaft through the working bodies of both treatment tools ments. Inside the hollow shaft, being in threaded engagement with it, a screw is coaxially located with the possibility of longitudinal movement during rotation relative to the hollow shaft and at the same time passes through a hole in the axis connecting the working bodies of both cleaning tools and is equipped with a limiter or protrusion at the end of the screw (RF patent 2201813 , Portable demolition-cleaner, Tretyakov G.M., Goryushinsky V.S., Goryushinsky I.V., Shur V.L., Kozhevnikov V.A., IPC B08B 9/08, B65D 88/68, publ. 10.04 .2003 Bull. No. 10).

The disadvantage of this device is the low cleaning efficiency in hard-to-reach places of the inner surfaces of containers or bunkers, since the area of the bearing surfaces of the collapsing elements is not enough to completely destroy the arches of caked loose bulk material, the achieved level of cleaning the container from caking material remains unknown.

The authors chose this technical solution as a prototype.

The technical result of the invention is to improve the quality of cleaning hard-to-reach spots on the inner surfaces of containers by increasing the coverage area of the cleaning.

The technical result is achieved by the fact that a portable demolition-cleaner of mostly inaccessible places of the inner surfaces of the containers, comprising a housing, a hollow drive shaft, rigidly connected to the working body with blades, a shank, which is located coaxially inside the hollow drive shaft with the possibility of longitudinal movement using the rod, according to The invention, in the device, the working body of the demolition cleaner is made in the form of a drill with blades and cutting edges, which is rigidly connected to one m the end of the shank, the other end of the shank is made with a threaded socket, enters the hollow drive shaft and interacts with the threaded socket with the shaft of the drive shaft, and a trapezoidal thread is made in the inner part of the casing-cleaner shaft, which interacts with the thread of the hollow drive shaft, also in the casing of the shredder -cleaner for the working body in the form of a drill on its shank installed and secured by a cylindrical hinge an additional working body in the form of wing-shaped links with a blade-like blade rhnostyu that its reverse side free to contact and deploy their end of the hollow drive shaft.

The links of the additional working body of the portable demolition-cleaner when exiting the housing are rotated through an angle of 90 ° using a hollow drive shaft.

A turnkey place is made in the hollow drive shaft of the device.

The additional working body of the portable demolition-cleaner is made of at least two links.

The portable demolition cleaner can be equipped with a device for controlling the speed of rotation of the drive shaft.

The presence of an additional working body makes it possible to increase the efficiency and quality of cleaning inaccessible places on the inner surfaces of containers or bins.

Figure 2 shows a view along arrow A of the main working body.

Figure 3 shows the minimum and maximum spread of the links of the additional working body.

A portable demolition-cleaner consists of a housing 1, a working body 2, blades of a working body 3, links of an additional working body 4, a hollow drive shaft having a surface section with a trapezoidal thread 5, a shank 6, a rod 7, a turnkey place 8.

Portable demolition-cleaner works as follows.

до его максимального значения

. Выбор начального перемещения штока 7, обусловливающего соответствующее увеличение угла «раскрытия» (подъем звеньев 4 вверх от крайнего нижнего положения), определяется физико-механическими характеристиками слежавшегося материала, то есть его сопротивляемостью при последующем воздействии сводообрушающих звеньев дополнительного рабочего органа 4. После этого вращением полого приводного вала 5 то в одну, то в другую сторону осуществляют его осевое перемещение вправо и влево. Операция проводится несколько раз до разрушения сводообразования. Если при данном угловом положении звеньев дополнительного рабочего органа 4 разрушения сводообразования слежавшегося материала не произошло, то в последовательности, изложенной выше, производят поочередное увеличение диаметра D_всэ, вплоть до его максимального значения

, и процесс разрушения сводообразования в бункере повторяют в аналогичной последовательности. По завершении процесса разрушения сводообразования путем вращения штока 7 в противоположную ранее проводимому вращению сторону возвращают звенья дополнительного рабочего органа 4 в исходное положение. Также в исходное положение возвращается резьбовой фиксатор. Затем вращением полого приводного вала 5 его перемещают вправо до упора в торец корпуса 1. Затем сводообрушитель отстыковывают от фланца бункерного устройства, а на его место устанавливают технологическую заглушку. Таким образом, производится сводоразрушение в полостях бункеров или контейнеров и очистка труднодоступных мест их внутренних поверхностей.Holes are pre-drilled in the walls of the hopper or container, mainly in hard-to-reach internal areas where it is most likely or known to cure the stored bulk material and form arches, and it is also possible for this material to stick to the walls of the container. After removing the plugs from these openings in the case of arches and the need to clean the walls of a layer of adhering material, the housing 1 of the portable demolition-cleaner is docked. Then, with the help of a key attached to the place 8 or with the help of a drive mechanism, the hollow drive shaft 5 is rotated along a trapezoidal threaded pair. The consequence of this is the displacement of the hollow drive shaft 5 to the left on the working stroke, determined by the contact surface of the bearing surface with the stop face of the flange of the hopper device. Moreover, on the entire specified working stroke of the hollow drive shaft 5, the rotating blades 3 of the working body 2 carry out loosening of caked material, contributing to the destruction of arising in the bunker. If, at the end of the hollow drive shaft 5, the specified collapse did not occur, then this drive shaft is moved to the right, then to the left, and so on several times, achieving destruction of the collapse. If the above process operation is negative, they proceed to the second stage of collapse destruction by including an additional working body 4 in the form of wing-shaped links with a blade-like surface. To do this, in the above sequence, by rotating the hollow drive shaft 5, a left stroke is made until the contact of its thrust surface with the surface of the flange of the hopper device. Then the threaded lock is screwed into the housing 1 by a fixed amount, guaranteeing the non-profit of the ends of the links of the additional working body 4 to the inner wall of the hopper device when moving the hollow drive shaft 5 from the extreme left position to the extreme right position. Subsequently, by rotation of the square-shaped head, the rod 7 is rotated, which moves to the right. Initially, the specified movement is selected within no more than 0.1 ... 0.2N, where H is the working stroke of the rod 7, in which the links of the additional working body 4 are deployed 90 ° from the initial position, that is, from the minimum diameter of the secondary demolition element

to its maximum value

. The choice of the initial movement of the rod 7, causing a corresponding increase in the angle of "opening" (raising the links 4 upward from the lowermost position), is determined by the physicomechanical characteristics of the caked material, that is, its resistance to subsequent exposure to the collapsing links of the additional working member 4. After this, the rotation of the hollow drive shaft 5 in one direction or the other, carry out its axial movement to the right and left. The operation is performed several times until the destruction of the arch formation. If, at a given angular position of the links of the additional working body 4, no collapse of the caking of the packed material occurred, then in the sequence described above, a successive increase in the diameter D is _{carried out} , up to its maximum value

, and the process of destruction of the arch formation in the hopper is repeated in the same sequence. Upon completion of the process of destruction of arch formation by rotating the rod 7 in the opposite direction to the previously conducted rotation, the links of the additional working body 4 are returned to their original position. The threaded lock also returns to its original position. Then, by rotating the hollow drive shaft 5, it is moved to the right until it stops at the end of the housing 1. Then, the demolition cage is undocked from the flange of the hopper device, and a technological plug is installed in its place. Thus, arch destruction is carried out in the cavities of bunkers or containers and the cleaning of inaccessible places of their internal surfaces.

The proposed portable demolition-cleaner provides simultaneous destruction of the arches and cleaning with an increased coverage area of inaccessible places of containers or bunkers.
