Description

The utility model relates to the field of metallurgy, in particular to apparatus for processing granular material by liquid under pressure, and can be used for desorption of various components from adsorbents, for example, from activated carbon, in technological processes for the extraction of precious metals.

A known apparatus for processing granular material with liquid (SU No. 647007, IPC B01J 8/00, B01J 3/04, published 02.15.1979), comprising a vertical housing with a lid, a movable container for the material to be processed, fluid inlet and outlet pipes connected to the tank , and a pipe for fluid intake from the housing, mounted in the cover.

A common feature of the claimed device with an analog is the presence of a sealed working chamber and nozzles for the input and output of liquid.

A disadvantage of the known apparatus is its low productivity, which is caused by the need to interrupt the process when loading and unloading the working chamber.

A known apparatus for processing granular material by liquid under pressure (RU No. 1361785, IPC B01J 4/00, published September 30, 1994), comprising a working chamber with fluid inlet and outlet pipes, loading and unloading mechanisms of the working chamber.

Common signs of an analogue with the claimed device are the presence of a sealed working chamber with nozzles for input and output of liquid and the presence of loading and unloading devices.

A disadvantage of the known apparatus is also low productivity, which is caused by the need to interrupt the process when loading and unloading the working chamber using loading and unloading mechanisms.

Also known is a device for the continuous processing of granular material with liquid (SU No. 1824755, IPC B01J 8/00, 03/15/1988), containing a working chamber with fluid inlet and outlet pipes located at opposite ends of the working chamber, equipped with loading and unloading containers located respectively above and below the working chamber and the valves connected to it.

Common signs of an analogue with the claimed device are the presence of a sealed working chamber with fluid inlet and outlet pipes and the presence of loading and unloading containers (locks) connected by valves.

The disadvantage of this device is the difficulty of ensuring a constant level (volume) of granular material in the working chamber.

As a prototype, an apparatus for processing granular material with liquid was taken (RU No. 155026, IPC B01J 8/00, published September 20, 2015).

 Common signs of an analogue with the claimed device are the presence of a sealed working chamber with fluid inlet and outlet pipes and the presence of loading and unloading containers (locks) connected by valves.

The disadvantage of the prototype is the low valve durability during operation of the device.

The objective of the utility model is to increase the operational properties of the device.

The technical result of the claimed utility model is to increase the durability (increase the service life) of the valves of the loading gateway.

The technical result is achieved by the fact that in the inventive apparatus for processing granular material with liquid under pressure, containing a working chamber with fluid inlet and outlet pipes located at opposite ends of the working chamber, loading and unloading locks located respectively above and below the working chamber and connected to it valves, loading gateway is made with a volume of 2 or more times the volume of the discharge.

A significant increase in the volume of the loading gateway allows to reduce the number of switching on valves of the loading gateway for processing a unit mass of the working medium.

The difference from the prototype is an additional two-fold increase in the volume of the boot gateway.

The presence of distinctive features allows us to conclude that the claimed device meets the criterion of "novelty."

The proposed device is illustrated in the drawing, where in FIG. 1 shows a general diagram of an apparatus for treating granular material with a liquid (sectional view).

The apparatus for processing granular material with liquid comprises a loading hopper 1 with granular material placed sequentially during the technological process, a loading valve 2, a loading gateway 3 and a discharge valve 4 of the gateway 3, which is connected by a pipe 5 to the working chamber 6. The length of the pipe 5 is determined by the position of the required level of the granular material in the working chamber. Below the working chamber 6 there is a loading valve 7 of the unloading lock 8, followed by a unloading valve 9 of the lock 8. Through the pipe 10, the spent granular material enters the tank 11. In the lower and upper part, the working chamber 6 is equipped with pipes 12 and 14. Above the level of the granular material a mesh 13 is installed to prevent the removal of granular material by the liquid. Ball valves can be used as valves 2, 4, 7 and 9.

The device operates as follows.

From the hopper 1, the granular material through the open valve 2 (with the valve 4 closed) fills the lock 3, after which the valve 2 closes. When the valve 4 is open, the granular material from the lock 3 through the pipe 5 enters the working chamber, supplementing it to the level of the lower end of the pipe 5. In the working chamber 6 the technological process of processing the granular material is continuously implemented. From the working chamber, the granular material with the open valve 7 and the closed valve 9 enters the lock 8. After filling the lock 8, the valve 7 closes. The granular material is unloaded from the lock 8 when the valve 9 is opened through the pipe 10 into the tank 11. At the next loading of the discharge lock (with the valve 4 open), the next portion of the granular material enters the working chamber from the loading lock. As a result of the synchronous movement of the granular material through the locks 2 and 8, the movement of the granular material through the working chamber 6 from top to bottom is ensured. At the same time, through the pipe 12, the working fluid is constantly supplied to the working chamber. Through the pipe 14, the working fluid from the working chamber 6 is discharged. As a result, the necessary processing process in the countercurrent of granular material and liquid is realized in the working chamber.

The increase in the volume of the loading gateway by several times makes it possible to significantly reduce the number of switching-on of its valves and, as a result, to increase their service life by several times.
