Description

one

The invention relates to the chemical treatment of products and can be used in various sectors of the industry where it is necessary to perform chemical treatment of products, for example, in the metallurgical and engineering industries to periodically pickle metal parts.

According to the main author. St. ff 639972 a device for covering chemical processing baths in a container is known, comprising a bath with a loading opening, sealing elements installed on both sides of the loading opening, and a system of blocks and flexible connections of the counterweight with a lid installed inside the bath P.

The disadvantages of this device are the lack of sealing of the baths at the time of loading and unloading the container with the products and the lack of sealing of the container when transporting the products removed

baths, as a result of which significant emissions of harmful vapors of the working solution into the atmosphere of the workshop are observed.

The purpose of the invention is the improvement of sanitary and hygienic conditions.

The goal is achieved by the fact that the device for covering chemical processing baths in a container is equipped with a frame made in the form of a crosspiece and a plate, rigidly connected by guides, a casing mounted on the guides with movement and additional sealing elements placed in the lower part of the casing the places of its coupling with guides and in the cover.

The drawing shows the proposed device, the cut.

Claims (1)

The device consists of a bath 1 and a container 2 for loading products. The container is mounted on a frame consisting of a plate 3 and a traverse, rigidly connected by guides 5. On the guides 5 there is installed a casing 6 with 3 sealing elements 7, made in the lower part along the perimeter, and sealing elements 8, made in places the mating of the guides 5 with the casing 6, the bath 1 has, in the upper part, bordering with 9 on the upper and lower surfaces of which around the perimeter there are installed sealing elements 10. The inner lid 11 is placed in the bath 1, made of an immersible material, for example poly ethylene which ibkimi bonds blocks 12 through system 13 is connected to counterweights. A sealing element 15 is mounted on the upper surface of the cover 11 along the perimeter. The sealing elements are made of an elastic material, for example rubber. The device works as follows. Prior to loading the container 2 with the products into the bath 1, its cover is carried out by a lid 11 installed inside the bath 1, which by the system of blocks 13 and flexible links 12 with counterweights 1 is pressed tightly against the sealing element 10 from the bottom side of the pan 9 1, a container 2 with articles is mounted by a lifting means, for example an electric loader (not shown in the drawing), and a plate 3, while the casing 6 is in the extreme upper position. After installing the container 2 on the plate 3, the cover b is moved to the lower position. A container 2 mounted on the plate 3 and covered with a casing b with lifting means, such as an electric hoist (not shown in the drawing), is mounted onto the inner cover 11 and together with it is immersed in the working solution 1b. The casing 6 at the same time under the force of the weight tightly pressed against the sealing element 1U, installed on the upper side of the rim board 9, do not allow the pair of working solution 16 to pass into the atmosphere of the workshop, and the plate 3 firmly pressed against the sealing element 15 mounted on the inner lid 11, without skipping the working solution 16 into the cavity between the plate 3 and the inner lid 1 G. 2 After finishing the treatment, the container 2 mounted on the plate 3 is removed from the bath 1 with a lifting means. The plate 3 is pressed tightly against the sealing element 7, The cover 11 installed in the lower part of the casing 6, j and inside the cover 11 returns to its upper position under the action of counterweights and covers the bath 1. Next, the container 2, sealed by the casing b and plate 3, is directed to a rinsing bath similar in design to the bath, and then into an oven with exhaust ventilation. The design features of the proposed device virtually eliminate the release of vapors of the working solution into the atmosphere of the workshop during the loading of containers into the bath and unloading, as well as eliminate the release of vapors of the working solution into the atmosphere of the workshop and leakage of its residues from the container with products during transportation. In this case, there is no need for local exhaust ventilation near the baths, the volume of general exchange of inlet-exhaust ventilation is significantly reduced, and the release of harmful substances into the environment is reduced. Formula of the invention Device for covering chemical processing baths in a container according to Avtsev, N 639972 guides, a casing installed on the guides with the possibility of movement and additional sealing elements, spread out in the lower part of the casing, during the month of its mating with the guides and in the lid.
