Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of multi-plate dewatering machines, and particularly relates to a multi-plate dewatering machine with buffered feeding. Background Technology
[0002] The multi-plate sludge dewatering machine is a new type of energy-saving and environmentally friendly equipment. It boasts numerous advantages, including energy saving, water saving, small size, ability to process oily sludge, continuous automatic operation, and easy maintenance. The multi-plate sludge dewatering machine consists of a box-type main unit containing two rows of filter media, fixed to the main shaft and constructed from stacked corrugated stainless steel plates. During operation, the flocculated sludge flowing into the main unit is first filtered and then concentrated as it moves forward. As the gap between the upper and lower filter media gradually narrows, the sludge is compressed and dewatered. Finally, the filter cake is discharged from the side of the box-type main unit.
[0003] For example, patent CN215828605U discloses a dewatering tank structure for a multi-plate circular sludge dewatering machine. The structure includes a tank body with a top cover. A discharge mechanism is located on one outer wall of the tank body. Several cylindrical filter elements are installed inside the tank body. Several servo motors are installed on one outer side of the tank body, with their output shafts connected to one end of the filter elements. A raw liquid inlet is located on the outer wall of the tank body away from the discharge mechanism. The discharge mechanism includes a discharge trough with a fixed base installed at its top. The fixed base is mounted on the inner wall of the tank body. A positioning plate is installed on the upper inner side of the discharge trough, and several electric push rods are mounted on the positioning plate. The filter elements in this multi-plate circular sludge dewatering machine's dewatering tank structure can squeeze and dewater the sludge, filtering out the water. The discharge mechanism further compacts the sludge, dewatering it into a cake shape, ensuring the sludge is firm and dry, facilitating collection, and improving the dewatering effect.
[0004] When using existing multi-plate dewatering machines, the wastewater enters the filter body too quickly, which exerts a large impact on the filter body and makes it prone to damage. Summary of the Invention
[0005] The purpose of this invention is to address the aforementioned technical problems by providing a multi-plate dewatering machine with buffered feeding, thereby preventing wastewater from entering the filter body too quickly and causing excessive impact on the filter body.
[0006] In view of this, the present invention provides a multi-plate dewatering machine with buffered feeding, including a feeding frame, a motor fixedly connected to the outer wall of the feeding frame, a rotating shaft fixedly connected to the output end of the motor, a buffer perforated plate fixedly connected to the inner wall of the feeding frame and sleeved on the outer wall of the rotating shaft, a rotating plate fixedly connected to the top end of the rotating shaft, a spring fixedly connected to the inner wall of the rotating plate, a telescopic column fixedly connected to the bottom end of the spring, a scraper fixedly connected to the bottom end of the telescopic column and fitting against the top end of the buffer perforated plate, a multi-plate dewatering machine body fixedly connected to one end of the feeding frame, a filter body provided on the inner wall of the multi-plate dewatering machine body, and a water collection tank provided below the filter body.
[0007] Based on the above structure, wastewater is slowly fed into the main body of the multi-plate dewatering machine through the through holes on the outer wall of the buffer plate. Then, the motor drives the rotating shaft to rotate, which in turn drives the rotating plate to rotate synchronously. This rotation of the rotating plate causes the scraper to rotate along the top of the buffer plate, scraping away the wastewater at the top of the buffer plate, which facilitates stable feeding. At the same time, the spring, through its own elasticity, drives the scraper at the bottom of the telescopic column to fit tightly against the top of the buffer plate, preventing the scraper from becoming worn and unable to scrape away the wastewater.
[0008] Preferably, the buffer perforated plate is disc-shaped, and the center of the buffer perforated plate coincides with the central axis of the rotating shaft. In this embodiment, it is convenient for sewage to slowly enter the main body of the multi-plate dewatering machine through the through holes on the outer wall of the buffer perforated plate.
[0009] Preferably, the scraper is parallel to the rotating plate, and the cross-section of the scraper is trapezoidal. In this embodiment, the rotation of the rotating shaft drives the rotating plate to rotate synchronously, so that the rotation of the rotating plate drives the scraper to rotate along the top of the buffer plate, scraping away the sewage at the top of the buffer plate, which facilitates stable feeding.
[0010] Preferably, the scraper is provided in two sets, and the two sets of scrapers are centrally symmetrical about the rotating shaft. In this embodiment, the spring drives the scraper at the bottom of the telescopic column to fit tightly against the top of the buffer plate through its own elastic force, so as to avoid the scraper becoming worn and unable to scrape off sewage.
[0011] Preferably, a feeding plate is provided on one side of the filter body, and an extrusion frame is fixedly connected to the top of the feeding plate. A bidirectional screw is provided inside the extrusion frame, and threaded sliders are threaded to both ends of the bidirectional screw. A connecting rod is hinged to the bottom end of the threaded slider, and a telescopic seat is slidably connected to the bottom end of the connecting rod and the inner wall of the extrusion frame. A pressure roller is rotatably connected to the outer wall of the telescopic seat. In this embodiment, the rotation of the bidirectional screw drives the two sets of threaded sliders to slide relative to each other. The sliding of the threaded sliders drives the telescopic seat to slide against the inner wall of the extrusion frame through the connecting rod. The sliding of the telescopic seat drives the pressure roller to approach the feeding plate, thereby extruding and discharging the impurities on the feeding plate.
[0012] Preferably, the feeding plate is in the shape of an inverted "V". In this embodiment, by setting the feeding plate in the shape of an inverted "V", it is beneficial to let the water generated by the extruded impurities flow into the water collection tank.
[0013] Preferably, the telescopic seat is parallel to the bidirectional screw. In this embodiment, the threaded slider slides through the connecting support rod to drive the telescopic seat to slide against the inner wall of the extrusion frame. The sliding of the telescopic seat drives the pressure roller to approach the feeding plate, thereby extruding and feeding the impurities on the feeding plate.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. This multi-plate dewatering machine with buffered feeding, by setting a buffer perforated plate, allows sewage to slowly enter the main body of the multi-plate dewatering machine through the through holes on the outer wall of the buffer perforated plate. Then, the motor drives the rotating shaft to rotate, and the rotating shaft drives the rotating plate to rotate synchronously. The rotation of the rotating plate causes the scraper to rotate along the top of the buffer perforated plate, scraping away the sewage at the top of the buffer perforated plate, which facilitates stable feeding. At the same time, the spring, through its own elasticity, drives the scraper at the bottom of the telescopic column to fit tightly against the top of the buffer perforated plate, preventing the scraper from becoming worn and unable to scrape away sewage.
[0016] 2. This multi-plate dewatering machine with buffered feeding, by setting a telescopic seat, the bidirectional screw rotation drives two sets of threaded sliders to slide relative to each other. The sliding of the threaded sliders drives the telescopic seat to slide against the inner wall of the extrusion frame through the connecting support rod. The sliding of the telescopic seat drives the pressure roller to approach the feeding plate, thereby extruding and discharging the impurities on the feeding plate. Attached Figure Description

[0024] This utility model discloses a multi-plate dewatering machine with buffered feeding, including a feeding frame 1. A motor 2 is fixedly connected to the outer wall of the feeding frame 1.

A telescopic column 7 is fixedly connected to the bottom end of the spring 6. A scraper 8, which is in contact with the top end of the buffer plate 4, is fixedly connected to the bottom end of the telescopic column 7.

A water collection tank 11 is provided below the filter body 10.
[0025] Based on the above structure, wastewater is slowly introduced into the main body 9 of the multi-plate dewatering machine through the through holes in the outer wall of the buffer plate 4. Then, the motor 2 drives the rotating shaft 3 to rotate, and the rotating shaft 3 drives the rotating plate 5 to rotate synchronously. The rotating plate 5 drives the scraper 8 to rotate along the top of the buffer plate 4, scraping away the wastewater at the top of the buffer plate 4, which facilitates stable feeding. At the same time, the spring 6 drives the scraper 8 at the bottom of the telescopic column 7 to fit tightly against the top of the buffer plate 4 through its own elasticity, so as to prevent the scraper 8 from being unable to scrape away the wastewater after wear.
[0026] In one embodiment, the buffer plate 4 is disc-shaped, and the center of the buffer plate 4 coincides with the central axis of the rotating shaft 3.
[0027] In this embodiment, by setting a disc-shaped buffer perforated plate 4, sewage is prevented from accumulating in the dead corners of the buffer perforated plate 4, and at the same time, it is convenient to thoroughly clean the buffer perforated plate 4; sewage can slowly enter the main body 9 of the multi-plate dewatering machine through the through holes on the outer wall of the buffer perforated plate 4.
[0028] In one embodiment, the scraper 8 is parallel to the rotating plate 5, and the cross-section of the scraper 8 is trapezoidal.
[0029] In this embodiment, the rotating shaft 3 drives the rotating plate 5 to rotate synchronously, so that the rotating plate 5 drives the scraper 8 to rotate along the top of the buffer plate 4, scraping away the sewage at the top of the buffer plate 4, which facilitates stable feeding.
[0030] In one embodiment, two sets of scrapers 8 are provided, and the two sets of scrapers 8 are centrally symmetrical about the rotating shaft 3.
[0031] In this embodiment, the spring 6 uses its own elasticity to drive the scraper 8 at the bottom of the telescopic column 7 to fit tightly against the top of the buffer plate 4, so as to prevent the scraper 8 from being unable to scrape away sewage after wear.
[0032] In one embodiment, a feed plate 12 is provided on one side of the filter body 10. An extrusion frame 13 is fixedly connected to the top of the feed plate 12. A bidirectional screw 14 is provided inside the extrusion frame 13. Both ends of the bidirectional screw 14 are threadedly connected to threaded sliders 15. A connecting support rod 16 is hinged to the bottom of the threaded slider 15. A telescopic seat 17 is hinged to the bottom of the connecting support rod 16 and slidably connected to the inner wall of the extrusion frame 13. A pressure roller 18 is rotatably connected to the outer wall of the telescopic seat 17.
[0033] In this embodiment, the rotation of the bidirectional screw 14 drives the two sets of threaded sliders 15 to slide relative to each other. The sliding of the threaded sliders 15 drives the telescopic seat 17 to slide against the inner wall of the extrusion frame 13 through the connecting support rod 16. The sliding of the telescopic seat 17 drives the pressure roller 18 to approach the feeding plate 12, thereby extruding and feeding the impurities on the feeding plate 12.
[0034] In one embodiment, the feed plate 12 is in the shape of an inverted "V".
[0035] In this embodiment, by setting an inverted "V" shaped feeding plate 12, it is beneficial to let the water generated by the extruded impurities flow into the water collection tank 11.
[0036] In one embodiment, the telescopic seat 17 is parallel to the bidirectional screw 14.
[0037] In this embodiment, the threaded slider 15 slides through the connecting support rod 16 to drive the telescopic seat 17 to slide against the inner wall of the extrusion frame 13. The telescopic seat 17 slides to drive the pressure roller 18 to approach the feeding plate 12, thereby extruding and feeding the impurities on the feeding plate 12.
[0038] In this embodiment of the multi-plate dewatering machine with buffered feeding, the operator first injects wastewater into the feeding frame 1. Through the buffer perforated plate 4, the wastewater slowly enters the main body 9 of the multi-plate dewatering machine through the through holes on the outer wall of the buffer perforated plate 4. Then, the motor 2 drives the rotating shaft 3 to rotate, and the rotating shaft 3 drives the rotating plate 5 to rotate synchronously. The rotating plate 5 drives the scraper 8 to rotate along the top of the buffer perforated plate 4, scraping away the wastewater at the top of the buffer perforated plate 4, which facilitates stable feeding. At the same time, the spring 6 drives the scraper 8 at the bottom of the telescopic column 7 to fit tightly against the top of the buffer perforated plate 4 through its own elasticity, so as to prevent the scraper 8 from being unable to scrape away the wastewater after wear.
[0039] Next, the working motor starts, driving the filter body 10 to rotate and peristalt the sewage, so that the water in the sewage passes through the filter body 10 and falls into the water collection tank 11, while the impurities move through the filter body 10 to the feed plate 12.
[0040] Finally, the operator rotates the bidirectional screw 14. The rotation of the bidirectional screw 14 causes the two sets of threaded sliders 15 to slide relative to each other. The sliding of the threaded sliders 15 causes the telescopic seat 17 to slide against the inner wall of the extrusion frame 13 through the connecting support rod 16. The sliding of the telescopic seat 17 causes the pressure roller 18 to approach the feeding plate 12, thereby extruding and discharging the impurities on the feeding plate 12.
