The utility model provides a solid-liquid separation device.

Referring to fig. 1 to 3, in an embodiment of the present invention, the solid-liquid separation apparatus includes a solid separation module 10, a pressure separation module 20 and a liquid accumulation box, the pressure separation module 20 is disposed above the liquid accumulation box, and the solid separation module 10 is disposed above the pressure separation module 20; the solid matter separation module 10 comprises a shell 11, a conical screen 12, a dirt guide pipe 13 and a first driving motor 14, wherein the first driving motor 14 is arranged outside the shell 11 and is axially connected with the conical screen 12, the cross section size of the conical screen 12 is gradually increased from the direction far away from the first driving motor 14, one end of the conical screen 12, facing the first driving motor 14, is arranged in the shell 11, one end of the conical screen 12, facing away from the first driving motor 14, extends out of the shell 11, and one end of the dirt guide pipe 13 is arranged in the conical screen 12; pressure separation module 20 includes at least one pressure separation unit 20a, pressure separation unit 20a includes second driving motor 21, action wheel 22, follows driving wheel 22a, first roll 24 and filter screen conveyer belt 25, second driving motor 21 connects action wheel 22, follow driving wheel 22a and pass through filter screen conveyer belt 25 connects action wheel 22, first roll 24 set up in centre gripping directly over action wheel 22 filter screen conveyer belt 25.

Specifically, in the present embodiment, the sewage is mainly filtered by the solid separation module 10 and the pressure separation module 20 in two steps:

firstly, the solid-liquid separation module 10 can perform preliminary solid-liquid separation on sewage, the sewage guide pipe 13 introduces the externally-connected sewage into the conical screen 12, and the opening of the sewage guide pipe 13 is close to the tip of the conical screen 12. The end of the conical screen 12 facing the first driving motor 14 is a closed end, and the end of the conical screen 12 facing away from the first driving motor 14 is an open end. As can be seen from the foregoing, the cross-sectional size of the conical screen 12 gradually increases from the direction away from the first driving motor 14, i.e. the tip of the conical screen 12 is connected to the first driving motor 14, and the bottom end thereof partially extends out of the housing 11. By adopting the conical screen 12 with the structure, solid particles with larger sizes in the sewage introduced by the sewage guide pipe 13 are firstly filtered out by the conical screen 12, and meanwhile, the separated solid particles can slide out of the screen under the action of gravity along the inclined inner net surface of the conical screen 12 so as not to block the sieve holes on the screen and influence the filtering effect. The conical screen 12 is rotated by the first drive motor 14 to avoid the accumulation of solid particles on the screen surface. In addition, in order to collect the slipping solid particles, a first solid guide groove 15 is arranged below the opening end of the conical screen 12, so that the slipping particles are accumulated in other collecting containers through groove bodies, and subsequent harmless treatment is facilitated.

Furthermore, the sewage primarily filtered by the solid separation module 10 is secondarily filtered by the pressure separation module 20. That is, the solid-liquid mixed pollutant introduced by the pollutant guide pipe 13 is separated from the large particles in the pollutant after flowing through the conical screen 12, and the pollutant after primary filtration flows out of the screen holes of the conical screen 12 and falls on the bottom of the shell 11 to be collected, and then flows into the pressure separation module 20 through the holes at the bottom of the shell 11. The pressure separation module 20 is composed of one or more pressure separation units 20a, and accordingly, a module structure composed of a plurality of pressure separation units 20a is more complicated and has a better filtering effect. The driving wheel 22 and the driven wheel 22a of the pressure separation unit 20a support the filter screen conveyer belt 25 at both ends, the driving wheel 22 is driven by the second driving motor 21 to rotate, and the second driving motor 21 is directly connected with or connected with the driving wheel 22 through gear transmission. The mixed attitude pollutant of solid-liquid after primary filter falls on filter screen conveyer belt 25 after being flowed out by solid-state thing separation module 10, and filter screen conveyer belt 25's direction of transfer is by following driving wheel 22a to action wheel 22, and on filter screen conveyer belt 25 can be stayed to great solid particle in this in-process pollutant, the liquid part can pass the sieve mesh on filter screen conveyer belt 25 and stay next grade. Meanwhile, when the solid particles remaining on the screen conveyer belt 25 are conveyed to the driving wheel 22, the solid particles are dewatered by the driving wheel 22 and the first roller 24 above the driving wheel, the residual liquid part in the solid particles is squeezed out, and the dewatered solid particles are discharged from the end of the driving wheel 22 and collected for subsequent treatment. In order to increase the collection effect, a second solid guide groove 26 can be added on one side of the driving wheel 22, so that the solid particles can be conveniently sorted and collected; and set up an elastic doctor-bar in the one end that second solid guide way 26 and filter screen conveyer belt 25 are close to, can scrape the solid particle who glues on filter screen conveyer belt 25 after squeezing, reduce the clearance work load in later stage.

In addition, only one pressure separation unit 20a is operated in this embodiment, but of course, in order to enhance the filtering effect, three pressure separation units 20a may be used in the pressure separation module 20 as shown in fig. 1 to perform the classification filtering, and a plurality of stages of pressure separation units 20a may be flexibly arranged according to actual conditions to achieve the filtering effect. It can be understood that sieve holes are formed in the conical screen 12 and the filter screen conveyer belt 25, and the sizes of the sieve holes are gradually reduced from large to small, so that classified filtration is realized; the mesh size of the screen conveyer belt 25 of the pressure separation unit 20a of each stage in one pressure separation module 20 is also from large to small.

As a preferred embodiment, the pressure separation unit 20a further includes an auxiliary wheel 27 disposed between the driving wheel 22 and the driven wheel 22 a; the pressure separation unit 20a further includes a second roller 28, and the second roller 28 is disposed right above the auxiliary wheel 27 to clamp the screen conveyer belt 25. The press filtering effect of the pressure separation unit 20a can be further improved by providing the auxiliary wheel 27 and the second roll 28 between the driving wheel 22 and the driven wheel 22 a.

In a preferred embodiment, the two ends of the first roller 24, the two ends of the second roller 28 and the two ends of the auxiliary wheel 27 are respectively connected with the adjustable bearing supports 29, so that the gap between the first roller 24 and the driving wheel 22 and the gap between the second roller 28 and the auxiliary wheel 27 can be adjusted according to the size of solid particles, and the filtering effect is enhanced.

As a preferred embodiment, a pneumatic cleaning module 30 is further arranged between the upper layer and the lower layer of the filter screen conveying belt 25, the pneumatic cleaning module 30 can blow air upwards and downwards to blow out solid particles clamped in the screen holes on the filter screen conveying belt 25, and the continuous filtering capacity of the filter screen conveying belt 25 is improved.

As a preferred embodiment, a solid-liquid diversion trench 23 is further arranged between the upper layer and the lower layer of the filter screen conveyer belt 25, and the filtered liquid is collected and discharged to the next-stage filtering unit, so that the splashing of the liquid is prevented from polluting a workplace.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structure changes made by the contents of the specification and the drawings under the inventive concept of the present invention, or the direct/indirect application in other related technical fields are included in the patent protection scope of the present invention.
