Description

Technical Field

[0002] With the rapid development of industrialization and urbanization, water pollution is becoming increasingly serious. Sewage treatment has become an essential part of environmental protection and sustainable development. Sewage treatment can not only effectively reduce water pollution and protect the ecological environment, but also is a key step in realizing the recycling of water resources. In the process of sewage treatment, solid-liquid separation is a crucial link, and its purpose is to remove suspended solids in sewage to preliminarily purify the water quality.

[0003] In existing sewage treatment, the method of solid-liquid separation generally uses the sedimentation method for solid-liquid separation. Under the action of gravity, suspended solids settle to the bottom of the sewage tank, and then the sediment at the bottom of the sedimentation tank is separated from water with the cooperation of a sieve, so as to achieve the purpose of solid-liquid separation.

[0004] At present, although sewage treatment equipment can achieve the purpose of solid-liquid separation, the separated solids contain a large amount of water. In order to reduce the waste of water resources, it is necessary to manually squeeze and filter the solids after solid-liquid separation a second time, so as to effectively reduce the water in the solids and thus reduce the waste of water resources. Therefore, it is necessary to design a solid-liquid separation device. Summary of the Invention

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0044] Referring to Figures 1 - 13 , a solid-liquid separation device provided by the present invention includes a base 1. A housing 2 is fixedly connected to the upper end of the base 1. A feeding assembly 11 is arranged at the rear end of the housing 2. A first discharge pipe 12 is fixedly connected to the lower end of the housing 2. A screening mechanism 3 is arranged inside the housing 2. A first extrusion mechanism 4 is arranged inside the lower end of the housing 2. The first extrusion mechanism 4 is used to perform the first solid-liquid separation on the solids screened by the screening mechanism 3. A guide chute 7 is fixedly connected to the lower end of the housing 2. First adjustment mechanisms 5 are arranged on both sides of the housing 2. The first adjustment mechanisms 5 are used to adjust the pressure of the first extrusion mechanism 4. A second extrusion mechanism 8 is arranged at the front end of the base 1. The second extrusion mechanism 8 is used to perform the second solid-liquid separation on the solids extruded and filtered by the first extrusion mechanism 4. A second adjustment mechanism 9 is arranged on the left side of the second extrusion mechanism 8.

[0045] Specifically, during use, the sewage and sediment in the sewage sedimentation tank are conveyed into the housing 2 through the feeding assembly 11 and then fall onto the screening mechanism 3. Under the action of the screening mechanism 3, the precipitated sewage can be preliminarily separated into solid and liquid. The solid matter after passing through the screening mechanism 3 enters the first extrusion mechanism 4. Under the action of the first extrusion mechanism 4, the liquid in the solid matter can be extruded. In this way, the first solid-liquid separation of the solid matter can be achieved under the action of the first extrusion mechanism 4. Before the first extrusion mechanism 4 works, the first adjustment mechanism 5 is used to adjust the pressure when the first extrusion mechanism 4 extrudes. The material extruded by the first extrusion mechanism 4 falls into the guide chute 7 and then enters the second extrusion mechanism 8 along the guide chute 7. Under the action of the second extrusion mechanism 8, the falling solid matter is continuously extruded, thus achieving the purpose of secondary solid-liquid separation, and better solid-liquid separation of the sewage can be achieved. At the same time, because the first extrusion mechanism 4 and the second extrusion mechanism 8 are integrally designed and the second extrusion mechanism 8 is located below the first extrusion mechanism 4, it is not necessary for workers to place the solid matter extruded by the first extrusion mechanism 4 into the second extrusion mechanism 8 again, thus reducing the labor intensity of workers. Before the second extrusion mechanism 8 works, the second adjustment mechanism 9 is used to adjust the extrusion pressure of the second extrusion mechanism 8 so that the extrusion pressure of the second extrusion mechanism 8 is greater than that of the first extrusion mechanism 4.

[0046] The feeding component 11 includes a feed pipe 1101, a regulating valve 1102, a square frame 1103, an overflow tank 1104 and a guide plate 1105. The rear end of the housing 2 is fixedly connected to the square frame 1103, and the square frame 1103 communicates with the housing 2. The lower end of the square frame 1103 is fixedly connected to the feed pipe 1101, and a regulating valve 1102 is installed on the feed pipe 1101. An overflow tank 1104 is fixedly connected inside the housing 2, and a guide plate 1105 is fixedly connected to the upper end of the overflow tank 1104. The guide plate 1105 is arc-shaped. During operation, the feed pipe 1101 is externally connected to a water pump, and the water pump is used to pump the sewage and sediment in the sewage sedimentation tank into the feed pipe 1101. Then, the regulating valve 1102 is operated to adjust the speed of material transportation. After the material enters the square frame 1103, it then enters the overflow tank 1104. After the overflow tank 1104 is filled with the material, it will flow outwards from the guide plate 1105 and fall on the screening mechanism 3, thus achieving the purpose of feeding.

[0047] The screening mechanism 3 includes a screen 301, a fixing frame 302, a vibration motor 303, a fixing plate 304 and a first spring 305. A fixing plate 304 is fixedly connected inside the housing 2, and a screen 301 is slidably connected inside the housing 2. A first spring 305 is fixedly connected between the screen 301 and the fixing plate 304. There are four first springs 305 and fixing plates 304, and they are distributed on both sides of the lower end of the screen 301. The front end of the screen 301 is fixedly connected to the fixing frame 302, and the front end of the fixing frame 302 is fixedly connected to the vibration motor 303. During operation, after the sediment and sewage fall on the upper end of the screen 301, the solid and liquid in the sewage can be preliminarily separated under the action of the screen 301 at this time. At this time, the solid remains on the upper end of the screen 301. Then, the vibration motor 303 works, and under the action of the first spring 305 and the fixing plate 304, the screen 301 can be driven to vibrate, thus cleaning the solid matter adhered to the screen 301 and facilitating the downward sliding of the solid matter.

[0048] The first extrusion mechanism 4 includes a first motor 401, a driving pressure roller 402, an auxiliary pressure roller 403 and a support plate 404. The driving pressure roller 402 is rotatably connected inside the housing 2. The first motor 401 is fixedly connected to the right side of the housing 2, and the output end of the first motor 401 is fixedly connected to the driving pressure roller 402.

The first threaded rod 503 is located inside the second spring 509. The square retaining block 508 is slidably connected to the cylinder 506. During operation, first adjust the pressure between the auxiliary pressure roller 403 and the driving pressure roller 402 according to requirements. When adjusting, turn the nut 504. At this time, with the cooperation of the auxiliary block 502, the first threaded rod 503 can be driven to move. As the first threaded rod 503 moves, the second spring 509 can be compressed with the cooperation of the square retaining block 508 and the retaining ring 505. The compressed second spring 509 can push the retaining ring 505 under the action of the reaction force. Then, with the cooperation of the cylinder 506 and the connecting plate 901, the support plate 404 is also pulled, so that the auxiliary pressure roller 403 presses the driving pressure roller 402, thereby changing the pressure between the auxiliary pressure roller 403 and the driving pressure roller 402. After the pressure is adjusted, the first motor 401 works, driving the driving pressure roller 402 to rotate. As the driving pressure roller 402 rotates, the auxiliary pressure roller 403 is also driven to rotate. In this way, with the cooperation of the auxiliary pressure roller 403 and the driving pressure roller 402, the extrusion of solid substances can be realized, and the excess liquid in the solid substances can be extruded, so as to realize the solid-liquid separation of sewage.

[0049] A scraper 6 is fixedly connected inside the material guiding groove 7. The scraper 6 cooperates with the driving pressure roller 402. During operation, by arranging the scraper 6, the solid substances adhered to the driving pressure roller 402 can be scraped off with the cooperation of the scraper 6, so as to achieve the purpose of cleaning the driving pressure roller 402, which is beneficial to the subsequent continuous extrusion operation of solid substances.

[0050] A flow guiding screen plate 13 is fixedly connected inside the housing 2. The flow guiding screen plate 13 is located at the lower end of the screening mechanism 3. During operation, by arranging the flow guiding screen plate 13, under the action of the flow guiding screen plate 13, it is beneficial for solid materials to enter between the active pressure roller 402 and the auxiliary pressure roller 403, thereby facilitating the extrusion operation of the materials.

[0051] The second extrusion mechanism 8 includes a collection tank 801, a second motor 802, a screw conveyor 803, a fixed cylinder 804, a filter screen cylinder 805, a liquid outlet 806, an extrusion plate 807, fixed ears 808, guide rods 809, a third spring 810, and a discharge hole 811.

During operation, first adjust the extrusion pressure of the extrusion plate 807. Rotate the handle 903 to drive the second threaded rod 902 to rotate. Then, with the cooperation of the connecting plate 901, the second threaded rod 902 can rotate and move at the same time. As the second threaded rod 902 moves, the moving disk 904 can be driven to slide on the guide rod 809. As the moving disk 904 moves, the third spring 810 on the guide rod 809 can be compressed. Under the reaction force of compressing the third spring 810, the extrusion pressure of the extrusion plate 807 can be changed. After adjusting the extrusion pressure of the extrusion plate 807, the second motor 802 works. With the cooperation of the screw conveyor 803, the solid matter can be conveyed through the discharge hole 811 into the filter screen cylinder 805 and then move along the filter screen cylinder 805, making the solid matter contact with the extrusion plate 807. After the solid matter contacts the extrusion plate 807, the liquid in the solid matter can be extruded under the cooperation of the extrusion plate 807 and then enter the fixed cylinder 804 and finally be discharged outwards through the second discharge pipe 14. At the same time, the extruded solid matter is discharged from between the extrusion plate 807 and the fixed cylinder 804. In this way, the solid-liquid separation of the solid matter is realized.
