Fig. 2 is a schematic diagram of the local relationship between the feed inlet and the vortex collection and settling bin.

Detailed ways

The utility model is described in detail below in conjunction with accompanying drawing:

In combination with Fig. 1, the utility model provides an anaerobic sand removal device, by improving the slurry pump of the prior art, especially changing the cavity structure of the existing slurry pump, that is, a vortex is arranged under the volute Collect the settling chamber, so that the anaerobic sand discharge device can automatically screen the conveyed slurry, so that the sediment contained in the conveyed material, such as: stones, glass fragments, sand and other particles, are pumped and collected by swirling flow and settled, while Only the slurry that has been filtered out of large-size particles is sent to the next-level processing unit, so the advantages of being transported slurry without plugging the pump body and reducing wear on the pump body can be achieved.

Specifically, the anaerobic sand discharge device includes: a volute 1 and a vortex collection settling bin 2 that communicates with the volute 1 and is located below the volute 1; and, the volute 1 and the vortex collection settling bin 2 are integrally formed;

Among them, the top of the volute 1 is provided with an impeller 4 driven by the motor 3; the upper right side of the volute 1 is provided with a discharge port 5; The bottom of the settling bin 2 is provided with a slag outlet 7, which also includes a delivery pipe and a collection box for convenience; the collection box is arranged below the slag outlet 7; the slag outlet 7 is connected to the collection box through the delivery pipe. An electric valve is installed on the conveying pipe, for example, a hydraulically driven electric valve.

In addition, the feed port 6 is arranged tangentially along the outer circumference of the vortex collection and settling bin 2, so as to increase the force of materials entering the vortex collection and settling bin 2.

In addition, a drainage port 8 is also provided at the feed end of the feed port 6 .

The working principle of the anaerobic sand discharge device provided by the utility model is:

The anaerobic sand discharge device has a self-priming function. When it is used for the first time, it is filled with the discharge medium from the drainage port to the inside of the cavity as the first drainage, and no drainage is required for subsequent use.

Then, when the material needs to be conveyed, the impeller inside the volute rotates rapidly, and the rotating blades cause the medium inside the cavity to rotate rapidly, and the rotating medium is discharged from the discharge port under the action of centrifugal force, so that the central part of the impeller forms a In the vacuum area, the material to be processed enters the vortex collection settling chamber through the feed inlet under the action of atmospheric pressure, and since the feed inlet and the outer circumference of the vortex collection settling chamber 2 are arranged tangentially, the material flows along a 45° The tangent enters the interior of the vortex collection and settlement chamber 2; when the material is sucked into the interior of the vortex collection and settlement chamber 2, the slurry inside the vortex collection and settlement chamber 2 can naturally form a vortex, so that the large particle size particles such as slag fragments that are larger than the specific gravity of the material The material is separated from the material and settled to the bottom of the vortex collection settling bin; while the slurry is discharged from the outlet through the pump body to the next-level processing unit. This achieves the purpose of separation and slag removal.

In actual use, the height of the vortex collection and settling chamber can be flexibly adjusted according to the nature of the material to be processed and the degree of fineness of separation. Normally, the height of the vortex collection and settlement chamber is 200mm-600mm.

In addition, the particles that settle into the vortex collection settling bin need to be cleaned regularly. When cleaning is required, only need to open the electric valve set in the bottom collection bin, and the particles in the vortex collection settling bin can be discharged through the conveying pipeline , has the advantage of being convenient for collection and cleaning.

It can be seen that the anaerobic sand discharge device provided by the utility model has the following advantages: according to the principle of the vortex, the slurry forms a vortex in the cavity, so that the substance with a specific gravity greater than water can be deposited at the bottom by rotation, and then The bottom pipe is collected into the tank, so the particles larger than the specific gravity of water do not pass through the impeller of the pump body, thereby reducing the problem of blockage and wear of the pump body by particles, and prolonging the service life of the pump body.

The above is only a preferred embodiment of the utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the utility model, some improvements and modifications can also be made, these improvements and Retouching should also be considered within the protection scope of the present utility model.
