Description

The invention relates to devices for removing harmful excreta and can be used in the chemical treatment of products in circumferential process baths.

The purpose of the invention is to increase the removal efficiency.

Fig, 1 shows the device, a general view; FIG. 2 is a section A-L in FIG. 1; FIG. 3 shows a device with products lowered into process baths.

The device for removing harmful emissions from the process baths 1, located around the circumference, contains a suction chamber consisting of individual shelters 2 of the processed products 3 according to the number of technological baths 1. Each of the shelters 2 is made of a flexible material, corrugated and provided with a support ring 4, Platform 5 mounted on the support 6, located in the center of the circle of the bath 1, can be rotated to move the shelters 2 along the technological baths 1, the support 6 is made hollow for communication with the air duct 7 and has openings 8 for passage of exhaust gases through its cavity. The annular manifold 9 is located under the platform 5 and is connected to the shelters 2 by means of cantilever nozzles 10. The corrugated sleeve 11 communicates with the manifold 9 and covers the support 6 with the possibility of rotation around its axis. The pipes 10 are rigidly connected to the collector 9 and installed in the openings 12 of the bridges 5, and the covers 2 are suspended at their free ends. The means 13 for vertically moving the covers 2 is rigidly connected to the platform 5 and the collector 9, for turning the platform serves as a drive 1-4,

The device works as follows.

A means 13 is included for the vertical movement of the shelters 2, which, with the fixed platform 5, lowers the collector 9 together with the cantilever nozzles 10, the shelters 2 with the products to be processed 3, the support rings 4 rest on the walls of the baths 1, the corrugated walls of the shelters 2 are compressed, and the products to be processed 3 immersed in the process fluid. At the same time, ensure the suction of harmful secretions of shelters 2 through cantilevered pipes.

10, the collector 9, the holes 8 of the support 6 in the duct 7,

After processing, the products 3 include means 13 for their vertical movement to the collector lifting mode 9. The cantilever branch pipes 10 together with the products 3 and the upper part of the shelters 2 are raised, and the corrugations of the shelters 2 under the influence of the weight of the support rings 4 are stretched and the products 3 are closed length, while ensuring effective removal of harmful exudates evaporating from their surface.

Include the actuator 14, which rotates the platform 5 together with the collector 9 and the cantilever branch pipes 10 to a new position. At the same time, the processed products 3 are moved from one bath to another and closed with 1 shelters 2, Then the products 3 are again lowered into baths 1, and the processing cycle is repeated.

The technical and economic efficiency of the proposed device as compared with the known one consists in reducing the emission of harmful substances by 1.6-1.8 times due to the corrugated walls of the shelters, which allows lifting and lowering the processed products and horizontal displacement while finding the products inside the shelters, and harmful excreta evaporating from their surface get directly into the suction nozzles.
