Description

Technical Field

[0001] This utility model relates to the field of filter press technology, specifically to the structure of an energy-saving and high-efficiency dewatering belt filter press for sludge dewatering machine rooms. Background Technology

[0002] A sludge belt filter press is a type of continuous operation equipment commonly used for sludge dewatering. It separates water from sludge through mechanical pressure, ultimately forming a filter cake with low moisture content.

[0003] In existing technologies, sludge in conventional belt filter presses falls directly from the conveying pipe onto the filter belt, which can easily lead to localized accumulation or uneven distribution, making it difficult to disperse quickly and evenly. If the sludge accumulates unevenly, water in thicker areas cannot be quickly discharged through the filter belt, while thinner areas may be over-dehydrated, causing the filter cake to crack. The accumulated sludge clumps may also clog the pores of the filter belt, affecting the filtrate permeability.

[0004] Therefore, it is necessary to propose an energy-saving and high-efficiency belt filter press structure for sludge dewatering rooms to solve or at least alleviate the above-mentioned defects. Utility Model Content

[0005] The purpose of this utility model is to provide an energy-saving and high-efficiency dewatering belt filter press structure for sludge dewatering machine rooms, so as to solve the problems mentioned in the background art, such as uneven sludge accumulation, where water in thick areas is difficult to be discharged quickly through the mesh belt, and thin areas may be over-dewatered, causing the filter cake to crack, and the accumulated sludge clumps may also block the mesh belt pores.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving and high-efficiency dewatering belt filter press structure for sludge dewatering machine rooms, including a belt filter press with a filter screen belt; an L-shaped support frame is installed on the belt filter press, a sludge conveying pipe is installed on the L-shaped support frame, a movable frame is slidably installed on the L-shaped support frame, the movable frame is slidably installed inside the belt filter press, a material feeding structure is connected to the movable frame, a connecting shaft is rotatably installed inside the movable frame, a material guiding structure is connected to the connecting shaft, and an adjustment structure is connected between the L-shaped support frame and the movable frame.

[0007] Preferably, the material feeding structure includes a slide rod, which is slidably installed inside the movable frame. Several material feeding rods are installed on the slide rod, and an electric push rod is installed on one side of the movable frame. The telescopic end of the electric push rod is installed at one end of the slide rod.

[0008] Preferably, the material guiding structure includes two spiral feeding plates, both of which are fixedly sleeved on the connecting shaft. A mounting frame is installed on one side of the movable frame, and a motor is installed on the mounting frame. The output end of the motor passes through the mounting frame and is fitted with a bevel gear one. A bevel gear two is installed at one end of the connecting shaft, and the bevel gear two meshes with the bevel gear one.

[0009] Preferably, a baffle plate is installed on the inner wall of the movable frame, and the baffle plate is located on one side of the spiral feeding plate.

[0010] Preferably, a spreading plate is installed on one side of the baffle plate, and the spreading plate is installed on the inner wall of the movable frame.

[0011] Preferably, the adjustment structure includes two lifting cylinders, both of which are installed above the movable frame, and the telescopic ends of both lifting cylinders pass through the movable frame and are installed above the L-shaped support frame.

[0012] Preferably, a guide rod is slidably mounted inside the movable frame, and the guide rod is mounted above the L-shaped support frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) In use, the sludge conveying pipe can be connected to the sludge conveying pipeline to convey the sludge to the feeding rod. At the same time, the electric push rod is turned on to drive the feeding rod to move back and forth, so that the feeding rod can push the sludge and spread it on the filter screen belt. Then, the motor is turned on to drive the two spiral feeding plates to rotate. While the filter screen belt is transporting sludge, the two rotating motors can push the sludge that exceeds its height to both sides, ensuring that the sludge can be evenly spread on the surface of the filter screen belt. This helps to improve the uniformity of the overall thickness of the sludge layer, so that water can penetrate evenly during the operation of the filter belt and shorten the dewatering time.

[0015] (2) This utility model can adjust the height of the movable frame, slide bar, connecting shaft, baffle plate and spreading plate by opening the lifting cylinder, so as to adjust the spreading thickness of sludge. Under the premise that the properties of sludge allow (such as good dewatering performance and low moisture content), the sludge processing capacity per unit time can be increased by thickening the spreading thickness.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figure 1-5 This utility model provides a technical solution: an energy-saving and high-efficiency dewatering belt filter press structure for sludge dewatering machine rooms, including a belt filter press 100, on which a filter screen belt 101 is provided; an L-shaped support frame 200 is installed on the belt filter press 100, a sludge conveying pipe 201 is installed on the L-shaped support frame 200, and a movable frame 202 is slidably installed on the L-shaped support frame 200, which is slidably installed inside the belt filter press 100. A material-pushing structure is connected to the movable frame 202, which is used to push the sludge flow to ensure that it can be spread on the filter screen belt 101. A connecting shaft 300 is rotatably installed inside the movable frame 202, and a material guiding structure is connected to the connecting shaft 300, which is used to push the sludge exceeding its height to both sides and spread the flow. An adjustment structure is connected between the L-shaped support frame 200 and the movable frame 202, which is used to adjust the spreading thickness of the sludge.

[0026] Furthermore, the material feeding structure includes a slide rod 203, which is slidably installed inside the movable frame 202. Several material feeding rods 204 are installed on the slide rod 203. An electric push rod 205 is installed on one side of the movable frame 202. The telescopic end of the electric push rod 205 is installed at one end of the slide rod 203. When the electric push rod 205 is activated, it drives the slide rod 203 to move back and forth, so that the slide rod 203 drives the several material feeding rods 204 to move back and forth. The reciprocating movement of the material feeding rods 204 helps to spread the sludge evenly on the surface of the filter screen belt 101.

[0027] Furthermore, the material guiding structure includes two spiral feeding plates 301, both of which are fixedly sleeved on the connecting shaft 300. A mounting frame 302 is installed on one side of the movable frame 202, and a motor 303 is installed on the mounting frame 302. The output end of the motor 303 passes through the mounting frame 302 and is fitted with a bevel gear 304. A bevel gear 305 is installed at one end of the connecting shaft 300. The bevel gear 305 meshes with the bevel gear 304. When the motor 303 is turned on, it drives the bevel gear 304 to rotate. The bevel gear 304 can drive the connecting shaft 300 to rotate through meshing with the bevel gear 305. The connecting shaft 300 will then drive the two spiral feeding plates 301 to rotate. Under the rotation of the spiral feeding plates 301 at both ends, sludge exceeding the height of the spiral feeding plates 301 can be pushed to both sides.

[0028] Furthermore, a baffle plate 306 is installed on the inner wall of the movable frame 202. The baffle plate 306 is located on one side of the spiral feeding plate 301. The baffle plate 306 can prevent sludge from overflowing from above the connecting shaft 300.

[0029] Furthermore, a spreading plate 307 is installed on one side of the baffle plate 306. The spreading plate 307 is installed on the inner wall of the movable frame 202. When the sludge moves with the filter press belt 101, it will come into contact with the spreading plate 307. The bottom surface of the spreading plate 307 is at the same height as the lowest point of the spiral feeding plate 301, so the spreading plate 307 helps to smooth the sludge.

[0030] Example 2: Figure 3-5 To facilitate adjustment of the sludge thickness on the spread, an adjustment structure is provided. The adjustment structure includes two lifting cylinders 400, both of which are installed above the movable frame 202. The telescopic ends of the two lifting cylinders 400 pass through the movable frame 202 and are installed above the L-shaped support frame 200. A guide rod 401 is slidably installed inside the movable frame 202 and is installed above the L-shaped support frame 200. Activating the lifting cylinders 400 can drive the movable frame 202 to rise. The moving movable frame 202 can drive the sliding rod 203, connecting shaft 300, baffle plate 306, and spreading plate 307 to rise, so as to adjust the sludge spreading thickness. The remaining features are the same as in Embodiment 1.

[0031] The working principle is as follows: During use, the sludge conveying pipe 201 is connected to the sludge conveying pipeline to transport sludge. Simultaneously, the electric push rod 205 can be activated to drive the slide rod 203 to reciprocate, causing the slide rod 203 to drive several material-pushing rods 204 to reciprocate. The transported sludge falls into the L-shaped support frame 200 and contacts the material-pushing rods 204. The reciprocating movement of the material-pushing rods 204 helps to spread the sludge evenly on the surface of the filter press belt 101. When using the belt filter press 100 to filter sludge, the filter press belt 101 can be used to transport the sludge. Simultaneously, the motor 303 can be activated to drive the first bevel gear 304 to rotate. The first bevel gear 304 can drive the connecting shaft 300 to rotate through meshing with the second bevel gear 305. The connecting shaft 300 then drives the two spiral material-pushing plates 301 to rotate. Since the connecting shaft 300 is equipped with two spiral material-pushing plates 301 facing opposite directions, they form... Figure 5 As shown, the rotation of the spiral feeding plates 301 at both ends can push the sludge exceeding the height of the spiral feeding plates 301 to both sides, ensuring that the sludge can be evenly spread on the surface of the filter screen belt 101. By opening the lifting cylinder 400, its telescopic end can be extended and drive the lifting cylinder 400 and the movable frame 202 to rise. When the movable frame 202 moves, it will slide on the guide rod 401. The guide rod 401 can limit the movement of the movable frame 202 in the vertical direction. The moving movable frame 202 can drive the slide rod 203, the connecting shaft 300, the baffle plate 306 and the spreading plate 307 to rise, so as to adjust the spreading thickness of the sludge.

[0032] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
