[0027] The utility model is further described below in conjunction with the accompanying drawings:

[0028] like Figure 1 — Figure 8 As shown, a solid-liquid separation device for environmental protection engineering includes a separation shell 101, a support seat 102 is welded to the side of the separation shell 101, a collecting cylinder 103 for collecting liquid is connected to the bottom of the separation shell 101 by bolts, a drainage hole (not shown in the figure) is arranged on the side of the collecting cylinder 103, and a hopper 104 is connected to the top of the separation shell 101 by bolts. The separation shell 101 is divided into an upper and lower part, a first separation mechanism for screening large particles is arranged on the upper part of the separation shell 101, and a second separation mechanism for solid-liquid separation is installed at the lower part of the separation shell 101. The support seat 102 is installed with a squeezing mechanism, and the second separation mechanism includes a plurality of parallel arranged transverse grid plates 301, and the transverse grid plates 30 1 is connected to the bottom side of the separation shell 101 by bolts. Two symmetrically arranged side fixing blocks 304 are connected in the separation shell 101 by bolts. The side fixing blocks 304 are located on both sides of the transverse grid plate 301. The upper side of the side fixing blocks 304 is rounded chamfered to prevent solids from remaining on the side wall of the separation shell 101. A circular filter screen 303 is fitted on the bottom of the transverse grid plate 301. The circular filter screen 303 is rotatably connected to the top of the collecting cylinder 103. A scraper 302 for cleaning the circular filter screen 303 is welded on the bottom of the transverse grid plate 301. When the circular filter screen 303 rotates, the scraper 302 can continuously scrape the top of the circular filter screen 303 to prevent the circular filter screen 303 from being blocked by solid particles.

[0029] In this embodiment, the extrusion mechanism includes a cylinder 401, which is connected to one side of the support seat 102 by bolts, and the output end of the cylinder 401 is connected to a push plate 402 by bolts, and the push plate 402 is slidably connected to the inside of the support seat 102, and the push plate 402 is connected to a push rod 403 by bolts on the side away from the cylinder 401, and one end of the push rod 403 is connected to an extrusion block 404 by bolts, and the width of the extrusion block 404 is the same as the gap between the transverse grid plates 301, and the bottom of the extrusion block 404 is provided with a scraper 30 2, the extrusion block 404 is used to scrape the side of the transverse grid plate 301 and squeeze the solid between the transverse grid plates 301. When the solid-liquid mixture enters the transverse grid plates 301 for solid-liquid separation, the output end of the cylinder 401 periodically expands and contracts, the cylinder 401 drives the push plate 402 to reciprocate, the push plate 402 pushes a plurality of push rods 403 to reciprocate, and the extrusion block 404 pushes and squeezes the solid-liquid mixture between the transverse grid plates 301 to squeeze out the liquid more fully.

The extrusion plate 406 is arranged on the opposite side of the support seat 102. A block 407 for limiting the extrusion plate 406 is welded on the side of the separation shell 101. The extrusion block 404 pushes the solid to the position of the extrusion plate 406. The liquid falls into the collecting cylinder 103 along with the circular filter screen 303. The solid after liquid separation accumulates at the position of the extrusion plate 406. After accumulation to a certain extent, the discharge is stopped, and the staff pulls out the extrusion plate 406 and uses the extrusion block 404 to push out the processed solid.

The output end of the No. 2 motor 305 is fixedly connected to the center position of the circular filter 303 by bolts, and a waterproof shell 306 is connected to the outside of the No. 2 motor 305 by bolts.

[0033] In this embodiment, the first separation mechanism includes a No. 1 motor 201, the output end of the No. 1 motor 201 is connected to a rocking plate 202 through a coupling, and a rocking arm 203 is eccentrically arranged and rotatably connected on the rocking plate 202. A movable frame 204 is hinged at one end of the rocking arm 203 away from the rocking plate 202, and the movable frame 204 is slidably connected in the separation shell 101. A plurality of parallel arranged oblique grid plates 205 are connected in the movable frame 204 by bolts. When the No. 1 motor 201 is started, the No. 1 motor 201 drives the rocking plate 202 to rotate, the rocking plate 202 drives the eccentrically arranged rocking arm 203 to move, and the rocking arm 203 drives the movable frame 204 to vibrate left and right, so that large particles in the solid-liquid mixture fall into the No. 1 collection box 206 along the direction of the oblique grid plate 205. Through the setting of the first separation mechanism, large particles in the solid-liquid mixture are screened out, the sufficient extrusion of the solid-liquid mixture by the extrusion block 404 and the extrusion plate 406 is improved, and the degree of solid-liquid separation is improved.

[0034] In this embodiment, a No. 1 collecting box 206 is welded to the outer side of the top of the separation shell 101, and the No. 1 collecting box 206 is located at the lower end of the inclined grid 205. A No. 2 collecting box 408 is welded to one side of the collecting tube 103, and the No. 2 collecting box 408 is located on the opposite side of the support seat 102.

[0035] Working principle: When the device is in use, the staff pours the solid-liquid mixture to be processed into the hopper 104, turns on the No. 1 motor 201 and the No. 2 motor 305, and controls the cylinder 401 to perform periodic telescopic movement. When the solid-liquid mixture enters the position of the mobile rack 204, the No. 1 motor 201 drives the rocking plate 202 to rotate, the rocking plate 202 drives the eccentrically set rocking arm 203 to move, and the rocking arm 203 drives the mobile rack 204 to vibrate left and right, so that the large particles in the solid-liquid mixture fall into the No. 1 collection box 206 along the direction of the oblique grid plate 205. After the large particles are screened out, the solid-liquid mixture enters the horizontal grid plate 301. The output end of the cylinder 401 periodically expands and contracts, and the cylinder 401 drives the push plate 402 to reciprocate, and the push plate 402 pushes a number of The push rod 403 moves back and forth, and the extrusion block 404 pushes and squeezes the solid-liquid mixture between the horizontal grid plates 301 to squeeze out the liquid more fully. The liquid flows into the collecting cylinder 103 through the circular filter screen 303. During the solid-liquid mixing process, the circular filter screen 303 rotates under the action of the No. 2 motor 305, and the scraper 302 can continuously scrape the circular filter screen 303 to prevent the circular filter screen 303 from being blocked by solid particles, thereby accelerating the separation efficiency. The solid after liquid separation accumulates at the position of the extrusion plate 406. After accumulation to a certain extent, the discharge is stopped, and the staff draws out the extrusion plate 406 and controls the cylinder 401 to push the extrusion block 404 to push out the processed solid, and the solid falls into the No. 2 collection box 408. Then the extrusion plate 406 is installed to continue the separation work.
