Description
Technical Field
[0001] This utility model relates to the field of mud and sand treatment technology, and in particular to an automatic mud and sand discharge device. Background Technology
[0002] Sediment refers to solid particulate matter composed of mud and sand. Its main components include fine soil particles, gravel, and rock fragments, with particle sizes between those of powdery particles and sand grains. Sediment is commonly found in water bodies such as rivers, beaches, lakes, and estuaries, and can also be present on land surfaces through wind or human movement. In these environments, the movement and deposition of sediment play a crucial role in the formation and evolution of landforms. Various sediment removal equipment is typically used in sediment management, such as screens, sedimentation tanks, centrifuges, sludge scrapers and suction dredgers, and sludge pumps.
[0003] In existing technologies, the wastewater treatment process requires the use of rotary bar screens to initially treat the sludge and sand in the wastewater. After filtering the sludge and sand, the rotary bar screen separates it from the wastewater and transports it upwards, allowing the sludge and sand to fall into the collection tank under gravity. However, the sludge and sand can stick to the screen and cannot fall off. Over time, this reduces the filtration efficiency of the screen, requiring workers to clean it, which is time-consuming and labor-intensive, thus reducing the efficiency of the rotary bar screen in wastewater treatment. Utility Model Content
[0004] The purpose of this invention is to solve the problem in the existing technology where, in the process of sewage treatment, a rotary bar screen is needed to initially treat the mud and sand in the sewage. After filtering the mud and sand, the rotary bar screen separates it from the sewage and transports it upwards, allowing the mud and sand to fall into the collection tank under gravity. However, the mud and sand stick to the screen and cannot fall off. Over time, this reduces the filtering effect of the screen on the sewage, requiring workers to clean the screen, which is time-consuming and labor-intensive, thus reducing the efficiency of the rotary bar screen in sewage treatment.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: an automatic sludge and sand removal device, comprising: a sewage treatment tank, wherein the sewage treatment tank is provided with a sewage trough, and a rotary bar screen is fixedly connected inside the sewage trough, and further comprising:

A cleaning roller is provided on the outer surface of the spline shaft. A motor is fixedly connected to one side of one of the fixed plates. The output end of the motor is fixedly connected to one end of the spline shaft. A movable ring is rotatably connected to the outer surface of the cleaning roller. A movable rod is fixedly connected to the outer surface of the movable ring. A fixed block is fixedly connected to the top of one of the fixed plates. The fixed block is slidably connected to the movable rod.
[0007] Preferably, a disc is fixedly connected to the other end of the spline shaft. The disc is inclined, and a groove is provided on one side of the disc. An arc-shaped slider is slidably connected inside the groove, and the arc-shaped slider is fixedly connected to the movable rod.
[0008] Preferably, a spline groove is provided at the center of the cleaning roller, and the outer surface of the spline shaft is slidably connected to the inside of the spline groove.
[0009] Preferably, a protective cover is fixedly connected to the top of the sewage treatment tank, the protective cover is fixedly connected to a rotary bar screen, and multiple diversion pipes are fixedly connected at equal intervals on the top of the protective cover, with a guide pipe fixedly connected to one end of each of the multiple diversion pipes.
[0010] Preferably, a fan is fixedly connected to the top of the protective cover, and a connecting pipe is fixedly connected to the air outlet of the fan. The connecting pipe is fixedly connected to the guide pipe, and the connecting pipe, the guide pipe, and the multiple branch pipes are interconnected.
[0011] Preferably, the wastewater treatment tank is provided with a collection tank, and a filter frame is slidably connected inside the collection tank, with a handle fixedly connected to one side of the filter frame.
[0012] Preferably, the sewage tank and the collection tank are connected, and an inlet pipe is fixedly connected to the side of the sewage treatment tank near the top, and the inlet pipe is connected to the sewage tank.
[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0014] 1. This utility model uses a controller to start a motor, causing its output shaft to rotate a splined shaft, which in turn rotates a cleaning roller. This cleans the mud, sand, and other debris from the rotary bar screen. Simultaneously, the rotation of the splined shaft drives a disc to rotate. With the disc's inclined arrangement, an arc-shaped slider slides within a groove. A force is applied to the arc-shaped slider, causing it to move a movable rod and a movable ring back and forth. The cleaning roller, in conjunction with the splined groove of the splined shaft and the cleaning roller, can slide left and right along the outer surface of the splined shaft while rotating within the movable ring. This back-and-forth movement of the cleaning roller allows for more thorough cleaning of the mud, sand, and other debris from the rotary bar screen, eliminating the need for manual cleaning. This process is time-saving and labor-saving, thus improving the efficiency of the rotary bar screen in wastewater treatment.
[0015] 2. In this utility model, the blower is started by the controller to generate gas, which then enters the connecting pipe, the guide pipe and the diversion pipe in sequence and blows towards the cleaning roller, blowing off the mud, sand and other debris stuck on the cleaning roller. This ensures that the cleaning roller continuously cleans the bar screen of the rotary bar screen cleaner. Attached Figure Description

[0026] Examples, such as Figure 1-6 As shown, this utility model provides an automatic sludge and sand removal device, including: a sewage treatment tank 1, a sewage tank 102, a rotary bar screen 101 fixedly connected inside the sewage tank 102, and two fixed plates 3, symmetrically fixedly connected to one side of the rotary bar screen 101. A spline shaft 303 is rotatably connected to the opposite side of the two fixed plates 3. A cleaning roller 302 is provided on the outer surface of the spline shaft 303. A motor 301 is fixedly connected to one side of one of the fixed plates 3. The output end of the motor 301 is fixedly connected to one end of the spline shaft 303. A movable ring 308 is rotatably connected to the outer surface of the cleaning roller 302. A movable rod 307 is fixedly connected to the outer surface of the movable ring 308. A fixed block 306 is fixedly connected to the top of one of the fixed plates 3. The fixed block 306 is slidably connected to the movable rod 307.
[0027] Furthermore, such as Figure 1-6As shown, a disc 305 is fixedly connected to the other end of the spline shaft 303. The disc 305 is inclined, and a groove 309 is provided on one side of the disc 305. An arc-shaped slider 310 is slidably connected inside the groove 309. The arc-shaped slider 310 is fixedly connected to the movable rod 307. By rotating the spline shaft 303, the disc 305 can be rotated. With the cooperation of the inclined setting of the disc 305, the arc-shaped slider 310 slides inside the groove 309, applying a force to the arc-shaped slider 310. With the cooperation of the fixed block 306 guiding the movable rod 307, the arc-shaped slider 310 drives the movable rod 307 and the movable ring 308 to move back and forth.
[0028] Furthermore, such as Figure 1-6 As shown, a spline groove 304 is provided at the center of the cleaning roller 302, and the outer surface of the spline shaft 303 is slidably connected to the inside of the spline groove 304. With the cooperation of the spline shaft 303 and the spline groove 304, the cleaning roller 302 can rotate with the rotation of the spline shaft 303, and the cleaning roller 302 can slide left and right along the outer surface of the spline shaft 303.
[0029] Furthermore, such as Figure 1-6 As shown, a protective cover 2 is fixedly connected to the top of the sewage treatment tank 1. The protective cover 2 is fixedly connected to the rotary bar screen 101. Multiple diversion pipes 204 are fixedly connected at equal intervals on the top of the protective cover 2. One end of each diversion pipe 204 is fixedly connected to a guide pipe 203. With the above arrangement, gas can enter the diversion pipe 204 through the guide pipe 203 and blow it toward the cleaning roller 302, blowing off the mud, sand and other garbage stuck on the cleaning roller 302.
[0030] Furthermore, such as Figure 1-6 As shown, a fan 201 is fixedly connected to the top of the protective cover 2. A connecting pipe 202 is fixedly connected to the air outlet of the fan 201. The connecting pipe 202 is fixedly connected to the guide pipe 203. The connecting pipe 202, the guide pipe 203 and multiple branch pipes 204 are connected to each other. The fan 201 is started by the controller to generate gas and allow the gas to enter the connecting pipe 202, the guide pipe 203 and the branch pipes 204 in sequence.
[0031] Furthermore, such as Figure 1-6 As shown, the sewage treatment tank 1 is equipped with a collection tank 103. A filter frame 104 is slidably connected inside the collection tank 103. A handle is fixedly connected to one side of the filter frame 104. The filter frame 104 filters mud, sand and other garbage, allowing water to flow through the filter frame 104 into the collection tank 103 and then back into the sewage tank 102. Finally, the filter frame 104 can be removed by the handle to clean the mud, sand and other garbage filtered by the filter frame 104.
[0032] Furthermore, such as Figure 1-6 As shown, the sewage tank 102 and the collection tank 103 are connected. The sewage treatment tank 1 is fixedly connected to the side near the top with an inlet pipe, which is connected to the sewage tank 102. The inlet pipe facilitates the delivery of sewage into the sewage tank 102.
[0033] Working principle: During use, sewage is discharged into the sewage tank 102 through the inlet pipe. The rotary bar screen 101 is then started by the controller, filtering out mud, sand, and other debris from the sewage and conveying it upwards. Simultaneously, the controller starts the motor 301, causing its output shaft to drive the splined shaft 303 to rotate, which in turn drives the cleaning roller 302 to rotate, cleaning the mud, sand, and other debris from the bar screen of the rotary bar screen 101. The rotation of the splined shaft 303 also drives the disc 305 to rotate, and the disc 305... With its inclined arrangement, the arc-shaped slider 310 slides inside the groove 309. A force is applied to the arc-shaped slider 310, causing it to drive the movable rod 307 and the movable ring 308 to reciprocate left and right. In conjunction with the splined shaft 303 and the splined groove 304 of the cleaning roller 302, the cleaning roller 302 can rotate with the splined shaft 303 while simultaneously sliding left and right along the outer surface of the splined shaft 303. At the same time, the cleaning roller 302 can rotate inside the movable ring 308. This allows the cleaning roller 302 to move back and forth, enabling it to clean the mud, sand, and other debris on the rotary bar screen 101 more thoroughly. This removes the debris without manual cleaning, saving time and effort and improving the efficiency of the rotary bar screen 101 in treating wastewater. Simultaneously, the controller starts the blower 201, generating gas which then sequentially enters the connecting pipe 202 and the guide pipe 203. The water is blown towards the cleaning roller 302 through the diversion pipe 204, causing the mud, sand and other debris stuck on the cleaning roller 302 to be blown off. This ensures that the cleaning roller 302 continuously cleans the rotary bar screen 101. The mud, sand and other debris are filtered through the filter frame 104, allowing water to flow through the filter frame 104 into the collection tank 103 and then back into the sewage tank 102. Finally, the filter frame 104 can be removed by the handle to clean the mud, sand and other debris filtered by the filter frame 104.
