Description

Technical Field

[0001] This utility model belongs to the technical field of sewage treatment equipment, and more specifically, it relates to a screw press. Background Technology

[0002] Screw presses are widely used in wastewater treatment and sludge dewatering. They are a type of solid-liquid separation equipment that can effectively separate solid particles and liquids in wastewater, reducing the suspended solids content and improving water quality.

[0003] The most common screw presses currently include annular plate cylinders and a spiral shaft passing through the annular plate cylinders. The annular plate cylinders are long cylindrical structures formed by multiple annular plates arranged closely along the axial direction. The gap between the spiral shaft and the annular plate cylinders is the filtration channel for the sludge to be treated. During operation, the screw shaft squeezes the sludge inside the annular plate cylinder. The water released from the sludge flows out through the gaps between the rings in the annular plate cylinder. The screw press is also equipped with a back pressure plate. By adjusting the gap of the back pressure plate, the moisture content of the discharged sludge can be adjusted. In practical applications, when the gap of the back pressure plate is lowered, although the moisture content of the discharged sludge is guaranteed, some sludge will be squeezed out from between the rings in the annular plate cylinder under the resistance of the back pressure plate. The squeezed-out sludge will fall into the filtrate tank below the screw press and enter the filtrate system with the filtrate. As a result, this part of the sludge will increase the concentration of suspended solids and COD in the filtrate, affecting the water quality of the effluent. On the other hand, this part of the sludge also has economic value, and its loss will reduce economic benefits. Utility Model Content

[0004] The purpose of this invention is to provide a screw press that aims to solve the problem caused by sludge falling from the ring plate assembly cylinder, as mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a screw press, comprising:

[0006] A frame, the bottom of which is provided with a filtrate tank;

[0007] The main body of the screw press is mounted on the frame, and the main body of the screw press includes an annular plate assembly mounted above the filtrate tank;

[0008] A conveyor is installed on the frame and located between the filtrate tank and the annular plate cylinder. The conveyor is used to receive sludge falling from the annular plate cylinder and transport the sludge to the outside of the frame.

[0009] In one possible implementation, the conveyor includes:

[0010] The first rotating roller is rotatably connected to the frame and located at the discharge end of the main body of the screw press;

[0011] The second rotating roller is rotatably connected to the frame and located at the feed end of the main body of the screw press. The annular plate cylinder is located between the first rotating roller and the second rotating roller.

[0012] A chain plate belt is wound around the first rotating roller and the second rotating roller, and the chain plate belt is used to catch the sludge falling from the ring plate assembly cylinder;

[0013] A first motor is mounted on the frame, and the drive end of the first motor is connected to either the first rotating roller or the second rotating roller to drive the chain belt to rotate and transport sludge.

[0035] Please see Figures 1 to 2 The present invention provides a screw press. The screw press includes a frame 1, a screw press body, and a conveyor. A filtrate tank 11 is provided at the bottom of the frame 1. The screw press body is mounted on the frame 1 and includes an annular plate assembly 2 positioned above the filtrate tank 11. The conveyor is mounted on the frame 1 and located between the filtrate tank 11 and the annular plate assembly 2. The conveyor is used to collect sludge falling from the annular plate assembly 2 and transport the sludge to the outside of the frame 1.

[0036] The present invention provides a screw press that, compared with the prior art, places a conveyor between the annular plate cylinder 2 and the filtrate tank 11. During sludge treatment, the conveyor can catch the sludge falling from the annular plate cylinder 2, preventing this part of the sludge from falling into the filtrate tank 11, and can also transport this part of the sludge to the outside of the frame 1 for collection and reuse, thereby increasing economic benefits.

[0037] In some embodiments, please refer to Figures 1 to 2The aforementioned conveyor includes a first rotating roller 31, a second rotating roller 32, and a chain belt 33. Both the first rotating roller 31 and the second rotating roller 32 are rotatably connected to the frame 1. The first rotating roller 31 is located at the discharge end of the screw press body, and the second rotating roller 32 is located at the feed end of the screw press body. The chain belt 33 is wound around the first rotating roller 31 and the second rotating roller 32 to collect sludge falling from the annular plate cylinder 2. In this embodiment, the annular plate cylinder 2 is located between the first rotating roller 31 and the second rotating roller 32. Between the two rotating rollers 32, the projection of the first rotating roller 31 on the horizontal plane is located outside the projection area formed by the filtrate tank 11 in the horizontal plane, and the projection of the second rotating roller 32 on the horizontal plane is located inside the projection area formed by the filtrate tank 11 in the horizontal plane. This arrangement allows the chain belt 33 to be located directly below the annular plate cylinder 2, and the length of the chain belt 33 in the horizontal direction to be greater than the length of the annular plate cylinder 2 in the horizontal direction, so that all the sludge falling from the annular plate cylinder 2 can be received by the chain belt 33. In this embodiment, the first motor is bolted and fixed to the frame 1. The drive end of the first motor can be connected to either the first rotating roller 31 or the second rotating roller 32. Optionally, the first motor is located at one end close to the first rotating roller 31 and is connected to the first rotating roller 31 through a gearbox. The first motor drives the first rotating roller 31 to rotate, which in turn causes the chain belt 33 to rotate around the first rotating roller 31 and the second rotating roller 32, transferring the sludge that falls on the chain belt 33 to the side of the first rotating roller 31 and then to the outside of the frame 1 for collection.

[0038] In some embodiments, please refer to Figures 1 to 2 In practical applications, a small portion of the sludge falling onto the chain belt 33 will adhere to the conveyor surface of the chain belt 33 and will be conveyed to the top of the filtrate tank 11 after passing the first rotating roller 31. To prevent this part of the adhered sludge from falling into the filtrate tank 11, a scraper 6 is provided on the frame 1 to remove the sludge adhering to the conveyor surface of the chain belt 33. The chain belt 33 includes an upper belt body 331 and a lower belt body 332. The scraper 6 is located on the frame 1 near the first rotating roller 31 and below the lower belt body 332, outside the filtrate tank. In this embodiment, the upper end of the scraper 6 contacts the conveyor surface of the lower belt body 332. When the lower belt is conveyed to the filtrate tank 11, the scraper 6 can scrape off the sludge adhering to the conveyor surface of the chain belt 33, preventing it from being conveyed to the top of the filtrate tank 11 with the chain belt 33.

[0039] Optionally, the scraper 6 is inclined outward from top to bottom. This arrangement allows the scraper 6 to guide the removed sludge to fall outside the frame 1, preventing the sludge from falling into the frame 1.

[0040] In some embodiments, the lower end of the scraper 6 is hinged to the frame 1, and a torsion spring is provided at the hinge point between the scraper 6 and the frame 1. The elastic force provided by the torsion spring is used to drive the upper end of the scraper 6 to abut against the lower belt 332. With the above arrangement, the scraper 6 can pass over the one-sided protrusion provided on the chain belt 33, avoiding hard contact between the chain belt 33 and the scraper 6, which would cause damage to the scraper 6. Optionally, a rubber scraper is provided at the upper end of the scraper 6, and the scraper 6 contacts the transmission surface of the lower belt 332 through the rubber scraper.

[0041] In some embodiments, please refer to Figure 1 A roller brush 4 is also provided on the frame 1. The roller brush 4 is located above the annular plate assembly cylinder 2 and is arranged parallel to the annular plate assembly cylinder 2. The bristles on the roller brush 4 are in contact with the annular plate assembly cylinder 2 to remove sludge from the annular plate assembly cylinder 2. Specifically, a first rotating shaft 41 is inserted inside the roller brush 4. The roller brush 4 is rotatably connected to the frame 1 through the first rotating shaft 41. The first rotating shaft 41 is connected to the spiral shaft 21 of the screw press body through a transmission component 5. The transmission component 5 includes a first gear 51, a second gear 52, and a chain 53. The first gear 51 is mounted on the first rotating shaft 41, the second gear 52 is mounted on the spiral shaft 21 of the screw press body, and the chain 53 is wound around the first gear 51 and the second gear 52. This arrangement allows the roller brush 4 and the spiral shaft 21 of the screw press body to share a single drive motor, thereby reducing the number of drive motors used and saving manufacturing costs.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
