Description

The invention relates to the equipment of the finishing production of the textile industry and can be used in the process of anti-impregnation and subsequent drying of textile hoses, for example, flax & x fire hoses.

The known machine for impregnation and drying of fire hoses, containing a drum mounted on a hollow horizontal axis with a tubular holder for fire hoses, mounted on the ends of the hollow axis, above the drum means for drying fire hoses, and an impregnation bath under the drum , a means for rolling fire hoses and a system for feeding the solution and air into the impregnation bath and in the cavity of the fire hoses ij.

The disadvantages of the known machine include: inefficient and uneven along the length of the sleeve drying of the inner surface due to the supply of unheated air by the compressor, which, as it moves inside the hose, is quickly moistened, loses drying potential, which leads to the dew point and moisture transfer from the near end sleeves to the far end, the use of a compressor as an air blower does not allow recirculation of the exhaust air and its heating, the low productivity of the machine, due to a long duration of the process of drying the inner surface of the sleeve compared with the outer.

The purpose of the invention is to increase productivity and reduce energy costs.

The goal is achieved by the fact that a machine for impregnating and drying fire hoses containing a drum mounted on a hollow horizontal axis rotatably with tubular holders for firemen, hoses mounted at the ends of a full axis, located above the drum along it means for drying firefighters sleeves, under the drum, set a boiling bath, means for rolling fire hoses and the system

25 supplying the solution and air to the impregnating bath and in the cavity of the fire hoses, has additionally mounted tubular holders for fire hoses along the axis, with the floor axle mounted rotatably,

thirty

and its cavity is divided by partitions into two zgny, and the means for drying the fire arms is made in the form of nozzles connected to an air supply system having a fan, the discharge pipe of which is connected to one of the hollow axis zones and its suction inlet - with a different zone | axis, with some of the holders of fire hoses communicating with the suction zone of the hollow axis, and others with the discharge.

In the pipeline connecting the nozzles to the air supply system, a gate is installed.

Figure 1 shows the proposed machine for impregnation and drying of fire hoses, general view / in figure 2 - section A-A in figure x; Fig. 3 shows the assembly of the connection of the rotating hollow axis with the air duct; Fig. 4 shows the connection unit of the movable nozzle with the suction area of the hollow axis of the drum.

The fire-hose impregnation and drying machine consists of a drum 1, made in the form of perforated support plates 2, arranged parallel around the circumference, and face discs 3. The drum 1 support is a floor 4, mounted on ball bearings 5, inside a hollow axis 4 a longitudinal partition b and two transverse partitions 7 installed at the ends of the longitudinal partition b so that the hollow axis 4 is divided hermetically into two zones — suction and discharge. Each of the zones has tubular holders 8 and 9, to which the ends of the fire hoses 10 are attached with clamps for their registration and subsequent drying. The nozzles (in the discharge zone) 8 are stationary relative to the hollow axis 4, and the nozzles 9 (in the suction zone) have packing seals on the axis 4 and can rotate about the hollow axis 4 to adjust the tension of the hose wound on the drum, taking into account its shrinkage during impregnation and drying. The floor axis 4 has a chain drive sprocket 11, the pipes 12 and 13 with shut-off valves 14 and 15 mounted on them. The floor axis 4 is connected to the duct through flanged wedge valves 16 and 17 to switch from the impregnation mode to the drying mode of the fire hoses. The machine has a suction duct 18, steam heaters 19, a discharge duct 20 with outlet 21 for supplying heated air to the inside of the sleeve and outlet 22 for supplying heated air to the outer surface of the sleeve, an adjusting gate 23, a nozzle 24 with a gate for adjusting the recirculation, exhaust air, an air iodine system having a fan 25, bath 26

impregnating the sleeves outside, means 27 for rolling fire hoses with setting the roll 28 and driving wheels 29, heat insulating tent 30 with WINDOW 31 for filling and hauling the sleeves, nozzle 32 for removing the exhaust air and means for drying the fire hoses, made in the form of nozzles 33 associated with an air supply system.

Machine for impregnation and drying of fire hoses works as follows.

A fire hose 10 of standard length 20 m, wound into a roll 28, is mounted on means 27 for rolling fire hoses. The end of the sleeve is connected through the refueling-selective window 31 to the stationary nozzle 8 fixed to the axis 4 and fixed on it with a special clip. The drive, the drum 1 and the drive for means for rolling the fire hoses are turned on, the sleeve 10 is wound on the drum 1, and 27 for rolling the fire hoses is moved along the axis of the drum on the traveling wheels 29. After the hose 28 has been coiled, the second end of the hose 10 is fixed by a clip on the pipe 9 that is movable relative to the axis 4. In the same way, the other arms are wound and strengthened. and drum 1. In the Impregnation operation, the bath 26 is filled with the impregnation solution, the valves 16 and 17 are closed, the valves 14 and 15 are opened, the circulation pump is turned on (not shown in Fig. 1) and the drum 1 is driven. impregnation of sleeves produced by draining the impregnating solution from the bath

26 and the internal cavity of the sleeves through the pipes 12 and 13 and the circulation system of the solution into a special tank for heating the solution and the subsequent impregnation operation. The impregnating solution is drained from the inner cavity of the sleeves when the drum 1 is rotated. In the drying operation, the valves 14 and 15 are closed, the wedge valves 16 and 17 are opened, the circulation fan 25 is turned on, the steam in the heater 19 is turned on, and the exhaust fan is removed air through the nozzle 32. in the Sample operation, the drum 1 rotates in the opposite direction of winding the sleeves, and the means

The rolling of the fire hoses 27d returns to its original position.

The proposed device improves performance and reduces energy costs. .
