Description

Technical Field

[0001] This utility model relates to the field of sludge dewatering technology, and more specifically to an industrial sludge dewatering device. Background Technology

[0002] Industrial sludge dewatering is a common method for industrial sludge treatment. Dewatered sludge has a smaller volume, significantly reducing transportation and storage costs, and facilitating subsequent treatment, direct landfilling, incineration, or resource utilization. Dewatering removes free water and some interstitial water from the sludge, reducing the probability of heavy metals, pathogens, and other pollutants being washed into the environment by rainwater. The organic matter content of dewatered sludge increases, making it suitable as a raw material for organic fertilizer or a substrate for landscaping, achieving resource recycling. Belt sludge dewatering machines are commonly used sludge dewatering equipment. They hold the sludge between upper and lower filter belts, repeatedly squeeze it through multiple pressing rollers, and use the shearing force generated by the wave-shaped path of the filter belt to squeeze out the remaining water.

[0003] Insufficiency of existing technology: When existing belt sludge dewatering machines transport sludge to the filter belt through the feeding pipe, they cannot ensure that the sludge is evenly distributed on the filter belt and maintains a suitable thickness. Uneven sludge distribution affects the subsequent filtration effect; and during use, sludge is prone to remain on the filter belt, causing blockage and affecting the filtration effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an industrial sludge dewatering device, comprising a main body, and further comprising: a coating mechanism, a lower cleaning mechanism, and an upper cleaning mechanism. The top inner wall of the main body is fixedly connected to the top of the coating mechanism. The side of the lower cleaning mechanism is fixedly connected to the side of the main body. The side of the upper cleaning mechanism is fixedly connected to the inner side wall of the main body. The main body includes a housing, and a lower drive roller is movably sleeved on the inner side wall of the housing. The side of the lower drive roller is drively connected to a lower... The filter belt includes a lower pressure roller movably sleeved on the inner side wall of the housing, an upper drive roller movably sleeved on the inner side wall of the housing, an upper filter belt connected to the side of the upper drive roller, an upper pressure roller movably sleeved on the inner side wall of the housing corresponding to the lower pressure roller, a discharge hopper fixedly connected to the side of the housing corresponding to the lower filter belt, a baffle plate, an automatic telescopic rod fixedly connected to the top of the baffle plate, the top of the automatic telescopic rod fixedly connected to the top inner wall of the housing, and a distribution plate movably connected to the side of the baffle plate.

[0006] Furthermore, the material distribution plate has a triangular cross-section, a slider is fixedly connected to the side of the baffle plate, a groove is provided on the inner wall of the side of the housing, and the side of the slider is movably connected to the side of the groove.

[0007] Furthermore, a drive motor is fixedly connected to the side of the baffle plate, and a turntable is fixedly connected to the output shaft of the drive motor. A transmission rod is movably sleeved at the bottom end of the turntable via a pin. The bottom end of the transmission rod is movably connected to the top end of the distribution plate via a pin. A slide rail is provided on the side of the baffle plate, and an mounting block is fixedly connected to the side of the distribution plate. The side of the mounting block is movably connected to the side of the slide rail.

[0008] Furthermore, the structure of the upper cleaning mechanism is the same as that of the lower cleaning mechanism. The lower cleaning mechanism includes a mounting frame, the side of which is fixedly connected to the side of the housing. A pressure spring is fixedly connected to the inner wall of the side of the mounting frame, a connecting block is fixedly connected to the side of the pressure spring, a scraper is fixedly connected to the top of the connecting block, the bottom of the scraper is movably connected to the inner wall of the bottom of the discharge hopper, and the side of the scraper is movably connected to the side of the lower filter belt.

[0009] Furthermore, a limiting rod is fixedly connected to the inner side wall of the mounting bracket at the position corresponding to the pressure spring, and a limiting hole is opened on the side of the connecting block, with the side of the limiting hole movably connected to the side of the limiting rod.

[0010] Furthermore, an upper spray pipe is fixedly connected to the inner side wall of the housing, and a lower spray pipe is fixedly connected to the inner side wall of the housing.

[0011] Furthermore, a water guide groove is fixedly connected to the inner side wall of the housing corresponding to the position of the spray pipe, and a drain pipe is fixedly connected to the side of the water guide groove. A protective plate is fixedly connected to the inner top wall of the housing corresponding to the position of the automatic telescopic rod.

[0012] The technical effects and advantages of this utility model are as follows: 1. This utility model utilizes an automatic telescopic rod to extend and retract, moving a baffle plate up and down according to the properties of the industrial sludge to be processed. This ensures that the bottom of the baffle plate is at a suitable distance from the top of the lower filter belt. A drive motor rotates a turntable, causing one end of a transmission rod to rotate along a pin on the side of the turntable and the other end to rotate along a pin on the top of the distribution plate. This pushes the distribution plate to move laterally back and forth along the side of the baffle plate, improving the efficiency of sludge diversion. This ensures that the sludge is evenly distributed on the top of the lower filter belt, and the baffle plate flattens the sludge and maintains a suitable thickness, which is beneficial to improving the efficiency and quality of sludge dewatering.

[0013] 2. This utility model uses a pressure spring to push the connecting block so that the left side of the scraper is tightly attached to the side of the lower filter belt, avoiding gaps, and scraping off the sludge on the surface of the lower filter belt, which finally falls onto the discharge hopper for discharge. Similarly, the upper cleaning mechanism cleans the surface of the upper filter belt and removes surface debris. Both the upper and lower spray pipes spray high-pressure water to spray the upper and lower filter belts respectively, removing debris attached to the filter belt holes, preventing blockage, and ensuring the normal operation of the equipment.

[0016] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The industrial sludge dewatering device involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Reference Figures 1 to 4This utility model provides an industrial sludge dewatering device, including a main body 1, and further including: a coating mechanism 2, a lower cleaning mechanism 3, and an upper cleaning mechanism 4. The top inner wall of the main body 1 is fixedly connected to the top of the coating mechanism 2, the side of the lower cleaning mechanism 3 is fixedly connected to the side of the main body 1, and the side of the upper cleaning mechanism 4 is fixedly connected to the inner side wall of the main body 1. The main body 1 includes a housing 101, and a lower drive roller 103 is movably sleeved on the inner side wall of the housing 101. A lower filter belt 104 is drively connected to the side of the lower drive roller 103. A lower pressure roller 105 is movably sleeved on the inner side wall of the housing 101. An upper drive roller 109 is movably sleeved on the inner side wall of the housing 101. An upper filter belt 111 is drivenly connected to the side of the upper drive roller 109. An upper pressure roller 110 is movably sleeved on the inner side wall of the housing 101 at the position corresponding to the lower pressure roller 105. A discharge hopper 102 is fixedly connected to the side of the housing 101 at the position corresponding to the lower filter belt 104. The coating mechanism 2 includes a baffle plate 201. An automatic telescopic rod 202 is fixedly connected to the top of the baffle plate 201. The top of the automatic telescopic rod 202 is connected to the housing. The top inner wall of the baffle plate 201 is fixedly connected, and the side of the baffle plate 201 is movably connected to the distribution plate 203. Depending on the nature of the industrial sludge to be processed, the automatic telescopic rod 202 extends and retracts, driving the baffle plate 201 to move up and down, so that the bottom end of the baffle plate 201 is kept at a suitable distance from the top end of the lower filter belt 104. The lower drive roller 103 and the upper drive roller 109 are both equipped with drive motors on their sides. During use, the drive motors drive the lower drive roller 103 and the upper drive roller 109 to rotate, so that the lower filter belt 104 and the upper filter belt 111 are conveyed to the right, transporting the sludge to be processed. As the sludge is conveyed to the left side of the lower filter belt 104, it is conveyed to the right side. When it reaches the position of the coating mechanism 2, the distribution plate 203 divides the sludge to both sides, and the baffle plate 201 flattens the sludge and maintains a suitable thickness. When the sludge moves to the positions of the lower pressure roller 105 and the upper pressure roller 110, it is squeezed and dewatered. The water falls into the bottom of the casing 101 and is discharged. The upper cleaning mechanism 4 cleans the surface of the upper filter belt 111 to remove surface debris, and the lower cleaning mechanism 3 cleans the surface of the lower filter belt 104 so that the dewatered sludge falls onto the discharge hopper 102 and is discharged.

[0018] The material distribution plate 203 has a triangular cross-section to facilitate the diversion of sludge. A slider 206 is fixedly connected to the side of the baffle plate 201. A groove 112 is provided on the inner side wall of the housing 101. The side of the slider 206 is movably connected to the side of the groove 112. When the baffle plate 201 moves up and down, the slider 206 slides along the groove 112, so that the baffle plate 201 moves in the vertical direction.

[0019] The baffle plate 201 is fixedly connected to a drive motor 205 on its side. The output shaft of the drive motor 205 is fixedly connected to a turntable 209. The bottom end of the turntable 209 is movably connected to a transmission rod 207 via a pin. The bottom end of the transmission rod 207 is movably connected to the top end of the distribution plate 203 via a pin. A slide rail 204 is provided on the side of the baffle plate 201. An mounting block 210 is fixedly connected to the side of the distribution plate 203. The side of the mounting block 210 is movably connected to the side of the slide rail 204. The drive motor 205 drives the turntable 209 to rotate, causing one end of the transmission rod 207 to rotate along the pin on the side of the turntable 209 and the other end to rotate along the pin at the top end of the distribution plate 203. This pushes the distribution plate 203 to move laterally back and forth along the side of the baffle plate 201, improving the efficiency of sludge diversion and ensuring that the sludge is evenly distributed on the top of the lower filter belt 104.

[0020] The upper cleaning mechanism 4 has the same structure as the lower cleaning mechanism 3. The lower cleaning mechanism 3 includes a mounting frame 301. The side of the mounting frame 301 is fixedly connected to the side of the housing 101. A pressure spring 304 is fixedly connected to the inner wall of the side of the mounting frame 301. A connecting block 303 is fixedly connected to the side of the pressure spring 304. A scraper 302 is fixedly connected to the top of the connecting block 303. The bottom of the scraper 302 is movably connected to the inner wall of the bottom of the discharge hopper 102. The side of the scraper 302 is movably connected to the side of the lower filter belt 104. The pressure spring 304 pushes the connecting block 303 to make the left side of the scraper 302 stick tightly to the side of the lower filter belt 104 to avoid gaps. The sludge on the surface of the lower filter belt 104 is scraped off and finally falls onto the discharge hopper 102.

[0021] Among them, the inner side wall of the mounting bracket 301 is fixedly connected to the position of the pressure spring 304, and the side of the connecting block 303 is provided with a limit hole 306. The side of the limit hole 306 is movably connected to the side of the limit rod 305. When the pressure spring 304 extends and retracts, the limit rod 305 slides along the limit hole 306 to ensure that the scraper 302 moves along the direction of the discharge hopper 102.

[0022] The upper spray pipe 108 is fixedly connected to the inner side wall of the housing 101, and the lower spray pipe 107 is fixedly connected to the inner side wall of the housing 101. Both the upper spray pipe 108 and the lower spray pipe 107 are connected to the high-pressure water pump through connecting pipes, spraying high-pressure water to spray the upper filter belt 111 and the lower filter belt 104 respectively, removing the debris attached to the filter belt holes and preventing blockage.

[0023] The inner side wall of the housing 101 is fixedly connected to a water guide trough 106 corresponding to the position of the spray pipe 108. A drain pipe is fixedly connected to the side of the water guide trough 106. A protective plate 208 is fixedly connected to the inner top wall of the housing 101 corresponding to the position of the automatic telescopic rod 202. The water guide trough 106 collects the water sprayed from the water guide trough 106 to prevent water from being on the lower filter belt 104, and discharges it through the drain pipe on the side of the water guide trough 106.

[0024] The working principle of this utility model is as follows: Based on the required properties of industrial sludge to be processed, the automatic telescopic rod 202 extends and retracts, causing the baffle plate 201 to move up and down, maintaining a suitable distance between the bottom end of the baffle plate 201 and the top end of the lower filter belt 104. Both the lower transmission roller 103 and the upper transmission roller 109 are equipped with drive motors on their sides. During operation, the drive motors drive the lower transmission roller 103 and the upper transmission roller 109 to rotate, causing the lower filter belt 104 and the upper filter belt 111 to be conveyed to the right. The sludge to be processed is conveyed to the left side of the lower filter belt 104 and, as the lower filter belt 104 moves to the right, it reaches the coating mechanism 2. When it reaches the position, the drive motor 205 drives the turntable 209 to rotate, causing one end of the transmission rod 207 to rotate along the side pin of the turntable 209, and the other end to rotate along the top pin of the distribution plate 203, thereby pushing the distribution plate 203 along the baffle plate 204. The lateral reciprocating motion of the 01 side improves the efficiency of sludge diversion, ensuring that the sludge is evenly distributed on the top of the lower filter belt 104, and the baffle plate 201 flattens the sludge and maintains a suitable thickness; when the sludge moves to the position of the lower pressure roller 105 and the upper pressure roller 110, it is squeezed and dewatered, and the water falls into the bottom of the casing 101 and is discharged; the pressure spring 304 pushes the connecting block 303 to make the left side of the scraper 302 closely stick to the side of the lower filter belt 104 to avoid gaps, scraping off the sludge on the surface of the lower filter belt 104, and finally falling onto the discharge hopper 102 for discharge. Similarly, the upper cleaning mechanism 4 cleans the surface of the upper filter belt 111 to remove surface debris; the upper spray pipe 108 and the lower spray pipe 107 both spray high-pressure water to spray the upper filter belt 111 and the lower filter belt 104 respectively to remove debris attached to the filter belt holes and avoid clogging.

[0025] 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, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
