Abstract

This invention relates to a technique for the preparation of chemical reagents, in particular, to devices for producing solutions of mineral clogs and comrades. The purpose of the invention is to increase reliability and reduce operating costs. The tank contains a housing, chambers for dissolving coagulum and receiving a ready solution, a grate, a system for distributing compressed air, a water supply pipeline, a series of siphon tubes connected by a horizontal collector, equipped with an air vent tube, a siphon tube, a pipe for draining the solution and sediment discharge pipe. Installing a row of siphon tubes at an angle to the horizon ensures that the insoluble part to the joint is deposited on the inner surface of the tubes. This allows the use of both purified and uncleaned coagulum, which increases reliability and reduces operating costs. Gil 00 ate OS 4

The invention relates to a technique for the preparation of chemical reagents, in particular, to devices up to the half part of mineral coagulant solutions.

The aim of the invention is to improve the reliability of operation, and reduce operating costs.

The drawing shows a mortar tank, a section.

The mortar tank consists of a housing 1, chambers 2 and 3, respectively, dissolving the coagulum and receiving the finished solution, the grate 4, the compressed air supply and distribution system 5, the water supply pipe 6, a row of siphon tubes 7 connected by a horizontal collector 8, equipped with an air vent tube 9 and siphon tube 10, the pipe 11 removal of the solution of coagulant and perforated pipe 12 release sediment.

Buck works as follows.

The coagulum is loaded into the dissolving chamber 2, held at a certain distance from the bottom by the grate 4 and filled with water through the conduit 6. Thereafter, compressed air is supplied to the tank through the system 5 for bubbling. When the dissolution of the 30 active part of the coagulum is reached, the supply of compressed air is stopped. Then open the valve on the tube 9 and release the air from the manifold 8, releasing the air inlet, the valve is closed. Thereafter, the coagulum solution is taken up through the pipe 11. Since chambers 2 and 3 are communicating vessels in the initial period of operation, when the solution is taken from chamber 3, it is continuously replenished from chamber 2.

40 in order to increase reliability, reduce operating costs, the solution removal tool is made in the form of a row of siphon tubes installed at an angle to the horizon, obediglon tubes 7 contained suspended particles of an insoluble part of a horizontal collector contained in it, such as coagulum deposited on the inner 2 The tank with respect to nl, differs from the surface of the tubes and slides down u and with the fact that the tubes are installed with a continuous layer of sieges, which then are at an angle of 45–60 with respect to the bottom of the mortar tank and to the horizon.

is outputted at the end of the cycle through line 12. Thus, the cleaned solution enters chamber 3 without affecting the performance of the pumping equipment.

With a gradual decrease in the level of solution in chamber 3 below the top point of the collector 8, siphon removal of solution from chamber 2 begins to a predetermined minimum level. When this level is reached, the solution intake from chamber 3 is stopped, the valve on tube 9 opens, the siphon is discharged, the tank is emptied and ready to receive a new batch of coagulum.

Perform r yes tubes at an angle. 45 - 60 due to the fact that their location has maximum efficiency.

Thus, the proposed mortar tank makes it possible to take the solution to the fullest extent, to use both very clean and untreated coagulants, to ensure reliable operation of the pumping equipment, and to reduce operating costs.
