Description

Technical Field

[0001] The invention relates to the technical field of solid-liquid separation devices, in particular to an integrated solid-liquid separation device. Background Art

[0002] A solid-liquid separation device is a device that separates solids and liquids in a solid-liquid mixture. Among them, a filter press is a commonly used solid-liquid separation device. A filter press is a mechanical device that uses a special filter medium to apply a certain pressure to an object to allow liquid to seep out. It was used in chemical production in the early 18th century and is still widely used in chemical, pharmaceutical, metallurgical, dye, food, brewing, ceramics, and environmental protection industries. In the environmental protection industry, filter presses are widely used in sewage treatment.

[0003] At present, the widely used filter press mainly includes three parts: frame, clamping mechanism and filtering mechanism. The frame is the basic component of the filter press, with thrust plates and clamping heads at both ends, and the beams on both sides connect the two. The beams are used to support the filter plate, filter frame and clamping plate; the thrust plate is connected to the support to place one end of the filter press on the foundation. The middle of the thrust plate of the chamber filter press is the feed hole, and there are four holes at the four corners. The holes at the upper two corners are the inlet of washing liquid or compressed gas, and the lower two corners are the outlets (undercurrent structure or filtrate outlet); the clamping plate is used to clamp the filter plate and filter frame, and the rollers on both sides are used to support the clamping plate to roll on the track of the beam; the beam is a load-bearing component. When in use, a mechanical clamping mechanism or a hydraulic clamping mechanism is used to push the clamping plate to run along the track in the frame to clamp the filter plate and filter frame, so as to achieve the effect of squeezing and separating the water quality and solid impurities in the sewage. However, when the existing filter press performs solid-liquid separation on sewage, the amount of sewage fed and filtered in each cycle is small, and the efficiency of solid-liquid separation treatment of sewage is not high, thereby affecting the efficiency of the entire sewage treatment process.

[0051] In this embodiment, a slag discharge port is provided at a position on the outer wall of the base 100 corresponding to the bottom end of the cylindrical cavity 101 .

[0052] Working principle: When in use, the sewage input interface is connected to the feed interface 305; the sewage enters the inner cavity of the pressing cylinder 300 through the feed interface 305; the second motor 301 drives the screw 304 to rotate through the driving gear 302 and the driven gear 303; the rotating screw 304 drives the pressing disc 400 to move downward in the inner cavity of the pressing cylinder 300 under the guidance of the sliding sleeve relationship between the guide rod 801 and the guide hole 402; the pressing disc 400 squeezes the sewage during the downward movement; the water in the sewage enters the inner cavity of the annular shell 200 through the filtering effect of the filter cartridge 500, and is further discharged through the drain port 201; the pressing disc 400 continues to move downward until the water The water is completely squeezed out; when the pressing disc 400 moves to the lowest position, the water is squeezed out and the solid impurities are retained on the bottom disc 600. The pressing disc 400 forms a large pressure on the bottom disc 600 through the solid impurities. In addition, during the downward movement of the pressing disc 400, its edge scrapes the filter surface of the filter cartridge 500, thereby preventing the filter holes on the inner wall of the filter cartridge 500 from being blocked; thereby causing the support strip 800 to detach from the second rectangular groove 601 and maintain a tendency to enter the first rectangular groove 403; the bottom disc 600 compresses the spring 900 and moves downward. When the top surface of the bottom disc 600 is lower than the inner surface of the cylindrical cavity 101, When the top surface of the cavity is reached, the solid impurities slide and flow out of the cylindrical cavity 101; at this time, the first motor 102 rotates, and the ring body 701 rotates 360° under the guidance and support of the annular slide rail 702. The bottom disc 600 is connected to the support plate 703 through the spring 900 assembly, so that the bottom disc 600 rotates with the support plate 703. During the rotation, the bottom disc 600 continuously rubs and scrapes against the top surface of the inner cavity of the cylindrical cavity 101, so that the solid impurities on the bottom disc 600 are completely removed and fall into the cylindrical cavity 101. The scraper 704 passes under the pressing disc 400 and scrapes the bottom surface of the pressing disc 400 during the rotation with the ring body 701. Thereby, the solid impurities adhered to the bottom surface of the pressing disc 400 are completely scraped off; after the ring body 701 rotates 360°, the bottom disc 600 returns to the bottom of the pressing disc 400; at this time, the second motor 301 reverses, causing the screw 304 to reverse, thereby causing the pressing disc 400 to move upward, and the support strip 800 is disengaged from the first rectangular groove 403. The elastic force applied by the spring 900 to the bottom disc 600 causes the bottom disc 600 to be re-inserted into the opening on the top surface of the base 100, and at the same time, the support strip 800 enters the second rectangular groove 601 to facilitate the next cycle of solid-liquid separation process; the solid impurities in the cylindrical cavity 101 can be removed through the slag discharge port.
