SU922000A1 - Sluice gate for transloading of loose materials - Google Patents

Description

 .

The invention relates to pneumatic conveying and can be used in various industries, in particular, in the tire industry for the dosed supply of granular and lumpy materials, such as rubber and rubber granules into the pipeline of a pneumatic conveying installation, also for transferring from one container to another.

A lock gate for transferring bulk materials is known, comprising a housing and a rotor mounted in the housing, in the cylindrical surface of each of the end discs of which there is a groove for material from the zone between the disk and the end wall of the housing G1 adjacent to it.

However, due to the fact that the grooves for the material viewport are made only on the cylindrical surface of the disks, the material that falls in the area between the disk to the end wall of the housing is only removed from the peripheral part of this area. as a result of the presence of material in the middle part of the zone, friction of the disk against the material occurs, which necessitates an increase in the energy consumption for driving the rotor during rotation.

In addition, the presence of several grooves in the known gate on the cylindrical surface of the discs reduces its tightness.

The purpose of the invention is to reduce energy costs and improve the shutter tightness.

The delivered chain is achieved by the fact that on the surface of each disk adjacent to the end wall of the housing there is a spiral groove, the end of which is adjacent to the said groove.

K general view in section; Fig, 2 - the surface of the end disk of the rotor with a spiral groove; FIG. 3 is a view A of FIG. 2. 39 The lock valve consists of a housing 1 with loading and unloading openings, a rotor 2 with blades and end disks 3 having a spiral-shaped groove 4 on its surface, which ends with a groove 5 on the cylindrical surface of the disks. The housing has end walls 6. The corners of the groove 4 are made with a radius equal to the depth of the groove. Groove width 1015 mm. The spiral is made according to the formula:, where: p is the increment of the distance, which corresponds to the rotation at a given angle H of the spiral pitch d. The groove 5 is made at an angle to the cylindrical forming disk. The width of the groove 5 is equal to the width of the groove 4. The sluice gate works as follows. When the rotor 2 rotates, the bulk material, such as rubber granules and rubber granules in the tank above the inlet pipe, is poured into the pockets of the rotor and poured out through the outlet pipe into the pneumatic conveying system. At the moment the material is poured into the rotor pocket and during subsequent movement to the opposite part of the gate material, for example, rubber and rubber granules. It falls into the zone between the wall 6 and the end disk 3 of the rotor 2, where the grips% 777 // 0 is facing the spiral-shaped groove 4, moves (along the groove) from the central part to the periphery and is led out through the groove 5 into the rotor pockets 2. This eliminates jamming of the rotor, eliminating friction of the rotor disks on the material, i.e. energy consumption and air leakage are reduced. Claims of invention that, in order to reduce energy consumption and improve its tightness, a spiral groove is made on the surface of each disk adjacent to the end wall of the case; The groove is specified.
