Description

Technical Field

[0001] This utility model relates to the technical field of dewatering equipment, specifically to a sludge dewatering device. Background Technology

[0002] Sludge is a type of pollutant that often accumulates beneath sewage and is also a waste product generated during sediment production. These pollutants often contain a large amount of water, which makes it difficult to effectively purify the sludge and can lead to a waste of water resources, since the water discharged from the sludge can be purified and reused.

[0003] There are many ways to dewater sludge, the most common being centrifugal, screw press, and filter press. Centrifugal dewatering removes water from sludge by high-speed rotation. This method is widely applicable, but it can only process sludge in batches, not continuously. Furthermore, each batch requires a discharge process, which reduces dewatering efficiency. Therefore, a sludge dewatering device is proposed. Utility Model Content

[0005] As a preferred embodiment of this utility model, the conveying pipe is connected to the interior of the dewatering filter cartridge, the bottom side wall of the conveying pipe is inclined, the feed box is a through rectangular structure, and a sealing plate is telescopically connected to the inside of the feed box near the bottom end, the size of the sealing plate being the same as the bottom opening of the feed box.

[0007] As a preferred technical solution of this utility model, the end of the control plate away from the sealing plate is a semi-circular structure, the bottom of the control plate is an open structure, a half gear is provided in the middle of the control plate, and teeth are evenly fixedly connected to the opposite side walls of the control plate, and the half gear is meshed with the teeth.

[0008] As a preferred technical solution of this utility model, the top side wall of the control board is detachably connected to a top plate, the half gear is rotatably connected to the bottom side wall of the top plate through the top side wall, and a transmission shaft is fixedly connected in the middle of the bottom side wall of the half gear. One end of the transmission shaft extends into the drive box and is detachably connected to the output end of the driver.

[0009] As a preferred technical solution of this utility model, a motor is provided on the side of the processing tank away from the conveying pipe, one end of the dewatering filter cylinder is on the same plane as one end of the processing tank and is in a rotating relationship, the output end of the motor is detachably connected to the side wall of one end of the dewatering filter cylinder, and four discharge ports are evenly and continuously opened on the dewatering filter cylinder.

[0010] As a preferred embodiment of this utility model, a guide plate is fixedly connected to one end of the processing tank and the lower side wall of the discharge port.

[0011] This invention has the following advantages: the drive half-gear rotates, which drives the control board and the sealing plate to perform timed reciprocating motion. This allows for timed opening and closing of the bottom of the feed box, thus achieving timed material discharge. This prevents all the sludge from entering the dewatering filter cartridge at once, which would not only increase the operating burden of the dewatering filter cartridge but also affect the dewatering effect. Timed material discharge ensures that there is a gap between each batch of sludge, achieving continuous feeding while ensuring the dewatering effect of each batch of sludge. This enables continuous dewatering and improves the efficiency of dewatering. Attached Figure Description

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Please refer to the following: Figure 1-3 The present invention relates to a sludge dewatering device, comprising a treatment tank 1, an inner groove 14 inside the treatment tank 1, a dewatering filter cylinder 9 rotatably connected to the inner groove 14, three baffle plates 15 uniformly fixedly connected to the inner wall of the dewatering filter cylinder 9, the baffle plates 15 having an annular structure and an inner ring wall having a conical structure, a conveying pipe 2 fixedly connected to one end of the treatment tank 1, the conveying pipe 2 having an L-shaped structure, and a feed box 3 detachably connected to one end of the conveying pipe 2;

[0018] The conveying pipe 2 is connected to the interior of the dewatering filter cartridge 9. The bottom side wall of the conveying pipe 2 is inclined. The feed box 3 is a through rectangular structure. A sealing plate 4 is telescopically connected to the inside of the feed box 3 near the bottom. The size of the sealing plate 4 is the same as the bottom opening of the feed box 3. A control plate 5 is fixedly connected to the middle of one side wall of the sealing plate 4. A drive box 6 is detachably connected to the top side wall of the conveying pipe 2 opposite to the control plate 5. A driver is detachably connected inside the drive box 6. The end of the control plate 5 away from the sealing plate 4 is semi-circular. The bottom of the control board 5 has an open structure. A half gear 16 is set in the middle of the control board 5. Teeth 17 are evenly fixedly connected to the opposite side walls of the control board 5. The half gear 16 meshes with the teeth 17. A top plate 19 is detachably connected to the top side wall of the control board 5. The half gear 16 is rotatably connected to the bottom side wall of the top plate 19 through the top side wall. A drive shaft 18 is fixedly connected in the middle of the bottom side wall of the half gear 16. One end of the drive shaft 18 extends into the drive box 6 and is detachably connected to the output end of the driver.

[0019] The technical effect of this method is as follows: The sludge to be processed is placed into the feed box 3. The driver in the drive box 6 is started, which drives the half gear 16 to rotate via the transmission shaft 18. Through the meshing connection, the control plate 5 and the sealing plate 4 connected to it are driven to reciprocate synchronously. Since only half of the half gear 16 can mesh with the teeth 17, the timed reciprocating function can be realized, thereby realizing the timed feeding effect. This allows a gap to be left between each batch of feeding. In order to ensure that the sludge entering the dewatering filter cartridge 9 does not interfere with each other, a baffle plate 15 is connected inside the dewatering filter cartridge 9. This can delay the movement of the sludge to a certain extent, fully ensuring that each batch of sludge does not merge and interfere with each other. This allows each batch of sludge to be evenly distributed in the dewatering filter cartridge 9, reducing the operating burden of the dewatering filter cartridge 9, and improving the overall processing efficiency due to continuous processing.

[0020] A motor 8 is installed on the side of the processing tank 1 away from the conveying pipe 2. One end of the dewatering filter cylinder 9 is on the same plane as one end of the processing tank 1 and is in a rotating relationship. The output end of the motor 8 is detachably connected to the side wall of one end of the dewatering filter cylinder 9. Four discharge ports 11 are evenly opened through the dewatering filter cylinder 9. A guide plate 12 is fixedly connected to the side wall of one end of the processing tank 1 below the discharge port 11. The bottom side wall of the guide plate 12 is inclined. Support legs 7 are detachably connected to the bottom of the processing tank 1 near both ends. A fixing plate 10 is detachably connected to the side of one of the support legs 7 near the top. One end of the fixing plate 10 is detachably connected to the motor 8. The other end of the fixing plate 10 is detachably connected to one of the support legs 7. A drain port 13 is opened through the bottom side wall of the end of the processing tank 1 near the motor 8.

[0021] The technical effect of this method is as follows: Four discharge ports 11 are opened at one end of the dewatering filter cylinder 9. A sealing plate can be rotated and connected inside the discharge port 11. When the dewatered sludge moves to the position of the discharge port 11, it will squeeze the sealing plate and open the sealing plate, so that the sludge will be discharged without stopping the machine to discharge the material, thereby improving the processing efficiency. Under the action of gravity, the sludge will only move at the bottom of the dewatering filter cylinder 9. The size of the discharge port 11 is opened as needed, so that when the discharge port 11 rotates to the lower part, it will come into contact with the sludge that is just being discharged, thereby achieving the material effect. The established guide plate 12 ensures that the dry sludge is discharged smoothly and reduces the splashing of the high green color, while the dewatered water will be discharged and collected through the drain port 13.

[0022] Specifically, when using this invention, the driver inside the drive box 6 is started, and the half gear 16 is rotated via the transmission shaft 18. The half gear 16, through its meshing with the teeth 17, drives the control plate 5 and the sealing plate 4 to reciprocate. This causes the sealing plate 4 to extend and retract at the bottom of the feed box 3. Because only half of the half gear 16 can drive the control plate 5, the extension and retraction of the sealing plate 4 can be controlled at specific times, achieving a timed material feeding effect. This ensures that the sludge entering the dewatering filter cartridge 9 has a certain distance between each other, achieving continuous feeding without mutual interference. Thus, continuous processing is achieved, improving efficiency. To improve sludge dewatering efficiency, a discharge port 11 is opened on one side of the dewatering filter cylinder 9, and the treatment tank 1 is set in an inclined state. In this way, the sludge can be moved while dewatering by rotating the dewatering filter cylinder 9. Finally, the dewatered sludge is automatically discharged from the discharge port 11 without stopping the machine to discharge, while the water thrown out will be discharged through the drain port 13. Combined with timed feeding, the effect of continuous dewatering is improved. At the same time, a baffle plate 15 is connected to the inner wall of the dewatering filter cylinder 9, which can block the sludge moving in the dewatering filter cylinder 9 without affecting the normal dewatering movement of the sludge. Combined with timed feeding, it ensures that there is enough distance between each batch of sludge, ensuring relatively independent dewatering effect.

[0023] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0024] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.
