Abstract

The utility model relates to a fluorhydric acid purified liquid and solid separating rakeless settling tank, which is a settling tank with a cone bottom. A lining is made of engineering plastics; a reinforcing frame is made of steel plates out of the lining; the lining and the reinforcing frame jointly form a tank body; the center of the upper part of the tank is provided with a baiting tube; the periphery of the tank opening is provided with overflow flow channels. The angle of the tank bottom is 45-120 DEG; the center of the bottom is provided with a solid outlet. The fluorhydric acid purified liquid and solid separating rakeless settling tank has simple structure, low cost, power saving, and easy produce-operation, and can make the continuous or discontinuous separation.

Description

Fluorhydric acid purified liquid and solid separating rakeless setting path

The utility model is a kind of liquid-solid isolating nothing rake subsider that is suitable for, and being specially adapted to the liquid-solid separation of hydrofluoric acid purified does not have the rake subsider.

At present in the existing Acid of Hydrofluoric Acid Production technology of China, the liquid-solid separation of hydrofluoric acid purified all adopts the subsider that has the water screw rake to carry out, this rake need be furnished with step-down gear and motor drives, the solid matter of bottom aggradation is harrowed it to the middle part by rake, be interrupted discharge through escape orifice, liquid is flowed out by the top overflow of groove, reaches the purpose of liquid-solid separation.This subsider complex structure, consumption of power is big, and driving part breaks down easily, influences ordinary production, and rake needs to make of copper material concerning Acid of Hydrofluoric Acid Production, and the cost height is in case the deposition material is too much in the groove, then be difficult to raking and block inconvenient operation, often maintenance.Therefore this subsider is anxious to be waited to improve.

The purpose of this utility model provides a kind of simple in structure, cheap liquid-solid separation of hydrofluoric acid purified that is applicable to does not have the rake subsider.

The utility model is achieved in that the refining liquid-solid separation of hydrofluoric acid do not have the rake subsider and be one and have the awl subsider at the end, the lining lining that it makes groove by engineering plastics is made strengthening frame by steel plate outward, mutual group becomes cell body, the center upper portion of groove is a blanking tube, the notch periphery is provided with the overflow runner, the angle of bottom land is the 45-120 degree, and central authorities have solid outlet at the end.Be provided with liquid stream buffering breaker plate in the blanking tube, breaker plate is one or more layers.

This nothing rake subsider has been cancelled power set, and the subsider structure is simplified greatly, and manufacturing cost descends significantly, and saved nonferrous materials, less investment, for ease of maintenaince, production operation is easy, the bottom deposit material only need be opened outlet valve in the ordinary production, just can emit automatically, clear liquid emits through the overflow runner from the top periphery overflow, to reach liquid-solid isolating purpose, this sepn process can be carried out continuously, also can be interrupted and carry out.This subsider facts have proved, gets a desired effect fully.

Below in conjunction with accompanying drawing the utility model is described in further detail:

Fig. 1 does not have the structure iron of rake subsider for the refining liquid-solid separation of hydrofluoric acid

With reference to Fig. 1, this nothing rake subsider is one and has the awl subsider at the end, and it makes the lining 6 of groove by engineering plastics, and lining 6 is outer makes strengthening frame by steel plate, and mutual group becomes cell body 5, and cover plate 1 is housed on the groove, has covered people's velar plate 3 and cleaning orifice plate 4.The center upper portion of groove is a blanking tube 2, be provided with liquid stream buffering breaker plate 8 in the tube 2, this breaker plate can be provided with one or more layers, and breaker plate can adopt porous plate or overflow plate, and the notch periphery is provided with overflow runner 7, and have a liquid outlet, clear liquid after the separation is flowed out continuously automatically, and the angle of bottom land is the 45-120 degree, and central authorities have solid outlet at the end, solid deposits after the separation is emitted automatically, to finish the purpose of liquid-solid separation.

Claims

1, a kind ofly is applicable to that liquid-solid separation does not have the rake subsider in the Acid of Hydrofluoric Acid Production technology, it is one and has the awl subsider at the end, it is characterized in that it is made the lining [6] of groove by engineering plastics, lining [6] is outer makes strengthening frame by steel plate, mutual group becomes cell body [5], and the center upper portion of groove is blanking tube [2], and the notch periphery is provided with overflow runner [7], the angle of bottom land is the 45-120 degree, and central authorities have solid outlet at the end.

2, nothing rake subsider according to claim 1 is characterized in that being provided with in the blanking tube ［ 2 ］ liquid stream buffering breaker plate ［ 8 ］, and breaker plate is one or more layers.
