SU914313A1 - Apparatus for removing excess of impregnating composition applied on strip material - Google Patents

Description

The invention relates to equipment factories rubber industry, in particular to devices for removing excess impregnating composition deposited on a strip material, such as cord fabric.

A device for removing excess impregnating composition is known, which contains a chamber connected to the exhaust ventilation pipe on which nozzles are mounted for the directed supply of compressed air to the impregnated material, a conical settling pit, the lower end of which is introduced into the bath and buried in the impregnating composition, and the upper one with camera £ TS.

A disadvantage of this device is the removal of foam impregnating composition and its deposition on the surfaces of ducts and fans, which impairs sanitary and hygienic working conditions, requires frequent cleaning of the ventilation device.

Closest to the invention is a device for removing excess impregnating composition deposited on a strip material, containing a chamber with nozzles mounted on it for supplying compressed air to the impregnated material, a settling pit, the lower end of which is installed in the impregnating bath and connected to the nozzle exhaust ventilation transitional chamber for the release of compressed air.

In such a device, the transition chamber is formed by the side walls of the chamber and partitions mounted obliquely to the axis, forming a conical C23 opening that extends toward the exit end of the settling chamber.

The disadvantages of this device are: a large number of surfaces contaminated with an impregnating composition that are periodically 91

which cleaning of adhering impregnating composition; the complexity of the cleaning operations of the contaminated surfaces of the device, it is difficult to mechanize and now-time manual; difficult access to the surfaces to be cleaned.

The purpose of the invention is to improve the ease of maintenance of the device.

This goal is achieved by the fact that in the device containing a chamber with nozzles mounted on it for supplying compressed air to the impregnated material, a settling tank, the lower end of which is installed in the bath with impregnating composition, and a transition chamber for the outlet of the exhaust ventilation According to the invention, the transition chamber is installed outside the side surface of the settling pit and is connected by its cavity to the cavity of the settling pit through a window made in the side surface of the latter.

FIG. 1 shows schematically the device, a general view; in fig. 2 section aa in FIG.

The device comprises a chamber 1 with a lid 2 on which nozzles 3 are mounted, forming an interstock slot 4 for directing compressed air to remove excess impregnating composition from the strip material being processed, continuously moving in bath 5 with an impregnating compound, through the interstock slot 4.

The camera is connected with the conical shaft-sump 6, the lower end of which is placed in the bath 5 with an impregnating composition. Outside the side surface of the settling pit 6, a transition chamber 7 is installed, the cavity of which is connected to the cavity of the settling pit via a window 8 formed in the lateral surface of the latter.

The transition chamber has hatches 9 and 10 and is connected to the exhaust ventilation pipe 11.

The device works as follows.

The strip material continuously impregnated in the bath 5, for example, cord 12, passes into the interscale gap 4, where the excess impregnation

the composition is removed from the surface of the web by jets of compressed air supplied through the nozzles 3. The foam and exhaust air formed by blowing away, the air velocity decreases, which contributes to the impregnating foam composition on the mirror. Then the air changes its direction, passes through the window 8 and enters the transition chamber 7. At the same time, as a result of an abrupt change in the direction of movement, some of the suspended particles of the impregnating composition contained in it fall out of the air.

The air enters from the transition chamber into the connecting pipe 11 connected to the exhaust ventilation system, changing the direction of movement, as a result of which the remnants of suspended particles of the impregnating composition flowing down the walls of the transition chamber and the shaft are separated into the bath 5. Cleaning the working surfaces is performed through the cover 2 and hatches 9 and 10.

The use of the proposed device to remove excess impregnate the exact composition applied to the strip material at tire factories RTI will reduce the complexity of its cleaning by about 30% and improve sanitary and hygienic working conditions.

Claims (1)

Claim A device for removing excess impregnating composition deposited on a strip material, containing a chamber with nozzles mounted on it for supplying compressed air to the impregnated material, a settling pit, the lower end of which is installed in an impregnating bath, and a transition chamber connected to the exhaust ventilation pipe the output of compressed air and dry air, which is due to the fact that, in order to increase the convenience of servicing the device, the transition chamber is mounted outside the side surface of the sump pit and its joint cavity with the cavity through the settling shaft formed in the side surface of the last box.
