Description

Double-deck solid-liquid separation machine of shale shaker formula

Technical Field

The utility model relates to the technical field of solid-liquid separation equipment for underground mines, in particular to a vibrating screen type double-layer solid-liquid separator.

Background

The sewage and water inflow produced by the working surface of the mining area are large, and the coal slag or gangue slag containing a large amount of different particle sizes are mixed together and enter the sedimentation tank. If the sedimentation tank is not cleaned in time, the phenomenon that the sedimentation tank is full and fails can be caused. In order to ensure the normal water storage function of the sedimentation tank, the sedimentation tank must be cleaned in time. And the coal slime and various slurry components in the underground sediment are complex and have different particle sizes, so that the problem of coal slime dehydration treatment becomes difficult.

Disclosure of Invention

In order to solve the problem, the utility model provides a vibrating screen type double-layer solid-liquid separator. The equipment has the advantages of simple structure, convenience in installation, stable vibration, strong universality, thorough solid-liquid separation and high efficiency, and the condition that the material is blocked by the classified screening, concentration and dehydration can be effectively reduced.

The utility model is realized by the following technical scheme:

a vibrating screen type double-layer solid-liquid separator comprises a frame, wherein a material storage box is arranged at the bottom layer of the frame, and a screen box is arranged at the upper layer of the frame; a secondary sieve plate and a primary sieve plate are sequentially and obliquely arranged in the sieve box from top to bottom, discharge chutes are arranged at the tail ends of the secondary sieve plate and the primary sieve plate, and a distributor is arranged at the feed end of the primary sieve plate; in the sieve box, two vibrating motors and a cyclone are symmetrically arranged at the upper end of the secondary sieve plate; the feed inlet of the cyclone is connected with the storage box through a pipeline and a secondary feed pump, and the underflow port of the cyclone is connected to the secondary sieve plate through a pipeline; an overflow pipe is connected with an overflow port of the cyclone.

Due to the adoption of the technical scheme, the utility model has the beneficial effects that: the equipment has simple structure, convenient installation and stable vibration, and the special screen design can effectively reduce the condition of material blockage by classified screening, concentration and dehydration. The method can effectively reduce the content of coal slime in the discharged water, reduce the failure speed of filling sludge in a downstream sedimentation tank/sump, prolong the dredging period of a downstream water storage facility and reduce the underground drainage pressure of the mine.

Detailed Description

The utility model is further illustrated with reference to the following figures and examples.

A vibrating screen type double-layer solid-liquid separator comprises a frame 1, wherein a material storage box 3 is arranged at the bottom layer of the frame 1, and a screen box 2 is arranged at the upper layer; a secondary sieve plate 8 and a primary sieve plate 7 are sequentially and obliquely arranged in the sieve box 2 from top to bottom, the tail ends of the secondary sieve plate 8 and the primary sieve plate 7 are provided with a discharge chute 6, and the feed end of the primary sieve plate 7 is provided with a distributor 14; two vibrating motors 9 and a cyclone 12 are symmetrically arranged at the upper end of the secondary sieve plate 8 in the sieve box 2; the feed inlet 11 of the cyclone is connected with the storage box 3 through a pipeline 4 and a secondary feed pump 5, and the underflow port 13 of the cyclone is connected to the secondary sieve plate 8 through the pipeline 4; an overflow pipe is connected with an overflow port 10 of the cyclone.

The working engineering of the utility model is as follows:

the special pump for pumping and discharging conveys the coal slime water in the sedimentation tank and enters a primary sieve plate 7 through a distributor 14 for primary screening, coarse particles on the sieve are slipped off to a belt conveyor through a discharging chute 6 and are transported away, undersize materials flow into a storage box 3 and are pumped and discharged into a swirler 12 by a secondary feeding pump 5 for concentration and classification treatment, under the action of centrifugal force, centripetal force and gravity of the swirler, overflow water flows back to a ditch through an overflow pipe, concentrated particles flow into a secondary sieve plate 8 through a swirler underflow port 13 for further screening and dehydration, oversize materials generated by the secondary sieve plate 8 are slipped off to the belt conveyor through the discharging chute 6 and are transported away, and undersize materials flow back to the storage box 3 for circular dehydration.

The vibration of the primary sieve plate 7 and the secondary sieve plate 8 is that two symmetrical mining vibration motors 9 are used as vibration sources, so that materials are thrown up on a sieve screen and simultaneously move forwards in a straight line, and the materials are sieved by the sieve screen to generate oversize materials and undersize materials.
