Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a sludge removal device for wastewater treatment. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. It removes pollutants from wastewater through physical, chemical, and biological methods. Physical methods include sedimentation and filtration, which can separate solid impurities from wastewater. Chemical methods use chemical reactions, such as neutralization and oxidation-reduction, to treat specific pollutants. Biological treatment relies on microorganisms to decompose organic pollutants. Activated sludge and biofilm processes are common examples. Wastewater treatment prevents wastewater from polluting the environment and protects water resources. It is widely used in the treatment of urban sewage and industrial wastewater.

[0003] Existing technologies include, for example, the utility model with publication number CN221732483U. This utility model relates to the field of sewage treatment, specifically a sludge removal device for sewage treatment, belonging to the field of sewage treatment technology. It includes a sewage treatment tank and a detachable door installed at one end of the sewage treatment tank. An inverted U-shaped support plate is provided at the output end of the stroke drive mechanism and above the sewage treatment tank. The inner wall of the U-shaped support plate is connected to a lifting cross plate through a lifting component. The inner bottom wall of the sewage treatment tank is covered with a wire mesh, and a plastic bearing film is fixedly connected to the top surface of the wire mesh. One end of the wire mesh near the detachable door is fixedly connected to the inner bottom wall of the sewage treatment tank, and the other end of the wire mesh is fixedly connected to the lifting cross plate. It enables the wire mesh and the supporting plastic membrane to quickly discharge the sludge in the sewage treatment tank in one go, thus replacing the traditional push plate or sludge pump structure that discharges sludge slowly. It has the effects of fast sludge discharge speed, high sludge discharge efficiency, and reduced labor intensity. However, after long-term filtration, the surface of the filter screen accumulates debris, which can easily affect the filtration effect of the equipment and make maintenance inconvenient.

[0004] To address the problem of debris accumulating on the filter screen surface after prolonged filtration, which can affect the filtration efficiency of the equipment and make maintenance inconvenient, the existing technology involves disassembly and cleaning. However, this increases the difficulty of operating the equipment, leading to inconvenience in equipment maintenance. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where, after prolonged filtration, debris accumulates on the surface of the filter screen, easily affecting the filtration effect of the equipment and making maintenance inconvenient. Therefore, this invention proposes a sludge removal device for wastewater treatment.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a sludge removal device for sewage treatment, comprising a housing and a cleaning device. An inlet pipe is installed on one side of the housing, and a filter screen is installed on the inner wall of the housing. The cleaning device is installed within the inner wall of the housing and includes a frame. The frame is fixedly connected to the housing, and a rotating rod is fixedly connected to the lower surface of the frame. A filter screen is rotatably connected to the surface of the rotating rod, and a connecting rod is fixedly connected to the surface of the filter screen. A sliding sleeve is fixedly connected to the side of the frame near the connecting rod, and a locking block is slidably connected to the inner wall of the sliding sleeve. By setting up the cleaning device, pressing the locking block and rotating the filter screen causes it to collide with the vibrating rod, thus shaking off the sludge accumulated on the surface of the filter screen. The operation is simple and convenient. Afterwards, rotating the filter screen resets the filter screen, and the locking block automatically inserts into the connecting rod under the action of a pressure spring to complete the positioning. The entire process is highly efficient, maintaining good filtration performance of the filter screen and reducing the problem of reduced filtration efficiency due to sludge accumulation.

[0007] Preferably, the lower surface of the connecting rod is provided with a slot, and the locking block is inserted into the slot on the lower surface of the connecting rod. By setting the connecting rod and the cooperation design between the connecting rod and the locking block, the rotation and reset operation of the filter screen is simple and easy. The user only needs to press the locking block to rotate the filter screen to clean the sludge.

[0008] Preferably, the connecting rod is L-shaped, and a beater is fixedly connected to the side of the housing near the filter screen. The beater is inclined, and by setting the beater, a convenient way to clean the filter screen is provided. By rotating the filter screen to make it collide with the beater, the vibration force generated by the collision can shake off the sludge accumulated on the surface of the filter screen, realizing simple and efficient cleaning of the filter screen, reducing the long-term accumulation of sludge and affecting the filtration effect, and ensuring the continuous and effective operation of the sewage filtration process.

[0009] Preferably, a pressure spring is fixedly connected to the lower surface of the locking block. The side of the pressure spring away from the locking block is fixedly connected to the sliding sleeve. By setting the pressure spring, when the filter screen is rotated to reset, the connecting rod abuts against the locking block, and the locking block slides downward under force. After the connecting rod passes through the locking block, the pressure spring loses its restraint and generates elastic force, squeezing the locking block into the connecting rod to complete the positioning of the filter screen.

[0010] Preferably, the inner wall of the housing is provided with a sludge discharge port, and the inner wall of the housing is provided with a dredging device. The dredging device includes a mounting frame, which is fixedly connected to the housing. A servo motor is fixedly connected to the surface of the mounting frame. The drive end of the servo motor passes through the mounting frame and is fixedly connected to a drive rod. A dredging fan blade is fixedly connected to the side of the drive rod away from the servo motor. By setting up the dredging device, during the sewage filtration process, the dredging device can effectively prevent the sludge discharge port from becoming blocked. When the sludge discharge port is opened and the servo motor is started to drive the dredging fan blade to rotate, debris that may accumulate in the sludge discharge port can be cleaned in time, ensuring smooth sewage discharge and enabling the entire filtration system to operate continuously and stably, reducing filtration stagnation caused by sludge discharge port blockage, thereby maintaining a high filtration efficiency.

[0011] Preferably, the unclogging fan blades are located on the inner wall of the sludge discharge port, and the servo motor is located on the upper surface of the sludge discharge port. By setting the unclogging fan blades, when the sludge discharge port is opened after the sewage filtration is completed, the servo motor drives the unclogging fan blades to rotate in the sludge discharge port, which can effectively break and disperse the sludge, debris and other materials that may accumulate at the sludge discharge port, reduce their coagulation or accumulation and prevent sludge discharge port blockage, and ensure the smooth progress of the sludge discharge process.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] In this invention, by setting up a cleaning device and a dredging device, during use, pressing the locking block disengages it from the connecting rod, and then rotating the filter screen towards the beater rod causes the filter screen to collide with the beater rod. At this time, the sludge accumulated on the surface of the filter screen is shaken off. Then, rotating the filter screen back to its original position, when the connecting rod abuts against the locking block, the locking block slides downward under force. When the connecting rod passes through the locking block, the pressure spring loses its restraint and generates elastic force to squeeze the locking block into the connecting rod to complete the positioning. After the sewage is filtered, the sludge discharge port is opened, and the servo motor is started. The servo motor drives the dredging fan blades to rotate in the sludge discharge port, which helps to reduce the sludge discharge port blockage. By setting up this invention, pressing the locking block and rotating the filter screen so that it collides with the beater rod can shake off the sludge accumulated on the surface of the filter screen. The operation is simple and convenient. Afterward, rotating the filter screen back to its original position, the locking block can automatically insert into the connecting rod under the action of the pressure spring to complete the positioning. The whole process is efficient, can maintain the good filtration performance of the filter screen, and reduce the problem of reduced filtration efficiency due to sludge accumulation.

A water inlet pipe 2 is installed on one side of the box 1, a filter screen 3 is provided on the inner wall of the box 1, and the cleaning device 4 is installed in the inner wall of the box 1.

[0021] The specific setup and function of its cleaning device 4 and unblocking device 5 will be explained below.

[0022] In this implementation scheme: the cleaning device 4 includes a frame 42, which is fixedly connected to the housing 1. A rotating rod 41 is fixedly connected to the lower surface of the frame 42. A filter screen 3 is rotatably connected to the surface of the rotating rod 41. A connecting rod 43 is fixedly connected to the surface of the filter screen 3. A sliding sleeve 44 is fixedly connected to the side of the frame 42 near the connecting rod 43. A locking block 46 is slidably connected to the inner wall of the sliding sleeve 44. By setting up the cleaning device 4, pressing the locking block 46 and rotating the filter screen 3 so that it collides with the tapping rod 47, the sludge accumulated on the surface of the filter screen 3 can be shaken off. The operation is simple and convenient. Afterwards, the filter screen 3 is rotated to reset. Under the action of the pressure spring 45, the locking block 46 can automatically insert into the connecting rod 43 to complete the positioning. The whole process is efficient and can maintain the good filtration performance of the filter screen 3, reducing the problem of reduced filtration efficiency due to sludge accumulation.

[0023] Specifically, a slot is provided on the lower surface of the connecting rod 43, and the locking block 46 is inserted into the slot on the lower surface of the connecting rod 43. By setting the connecting rod 43 and the cooperation design between the connecting rod 43 and the locking block 46, the rotation and reset operation of the filter screen 3 is simple and easy. The user only needs to press the locking block 46 to rotate the filter screen 3 to clean the sludge.

[0024] Specifically, the connecting rod 43 is L-shaped, and a flap 47 is fixedly connected to the side of the housing 1 near the filter screen 3. The flap 47 is inclined, and by setting the flap 47, a convenient way to clean the filter screen 3 is provided. By rotating the filter screen 3 to make it collide with the flap 47, the vibration force generated by the collision can shake off the sludge accumulated on the surface of the filter screen 3, realizing simple and efficient cleaning of the filter screen 3, reducing the long-term accumulation of sludge and affecting the filtration effect, and ensuring the continuous and effective operation of the sewage filtration process.

[0025] Specifically, a pressure spring 45 is fixedly connected to the lower surface of the locking block 46, and the side of the pressure spring 45 away from the locking block 46 is fixedly connected to the sliding sleeve 44.

[0026] In this embodiment: by setting a pressure spring 45, when the filter screen 3 is rotated to reset, the connecting rod 43 abuts against the locking block 46, the locking block 46 slides downward under force, and after the connecting rod 43 passes through the locking block 46, the pressure spring 45 loses its restraint and generates elastic force, squeezing the locking block 46 into the connecting rod 43 to complete the positioning of the filter screen 3.

[0027] Specifically, the inner wall of the box 1 is provided with a mud discharge port, and the inner wall of the box 1 is provided with a dredging device 5. The dredging device 5 includes a mounting frame 52, which is fixedly connected to the box 1. A servo motor 51 is fixedly connected to the surface of the mounting frame 52. The drive end of the servo motor 51 passes through the mounting frame 52 and is fixedly connected to a drive rod 53. A dredging fan blade 54 is fixedly connected to the side of the drive rod 53 away from the servo motor 51.

[0028] In this embodiment: By setting up the unblocking device 5, the unblocking device 5 can effectively prevent the sludge discharge port from becoming blocked during the sewage filtration process. When the sludge discharge port is opened and the servo motor 51 is started to drive the unblocking fan blade 54 to rotate, the debris that may accumulate in the sludge discharge port can be cleaned in time, ensuring smooth sewage discharge and enabling the entire filtration system to operate continuously and stably, reducing filtration stagnation caused by sludge discharge port blockage, thereby maintaining a high filtration efficiency.

[0029] Specifically, the dredging fan blade 54 is located on the inner wall of the sludge discharge port, and the servo motor 51 is located on the upper surface of the sludge discharge port.

[0030] In this embodiment: by setting up the unblocking fan blade 54, after the sewage filtration is completed and the sludge discharge port is opened, the servo motor 51 drives the unblocking fan blade 54 to rotate in the sludge discharge port, which can effectively break and disperse the sludge, debris and other materials that may accumulate at the sludge discharge port, reduce their coagulation or accumulation and prevent sludge discharge port blockage, and ensure the smooth progress of the sludge discharge process.

[0031] Working principle: With the cleaning device 4 and the unblocking device 5 in place, during use, press the locking block 46 to disengage it from the connecting rod 43, then rotate the filter screen 3 towards the beater 47. The filter screen 3 collides with the beater 47, causing the accumulated sludge on its surface to be shaken off. Then rotate the filter screen 3 back to its original position. When the connecting rod 43 abuts against the locking block 46, the locking block 46 slides downwards under force. When the connecting rod 43 passes through the locking block 46, the pressure spring 45 loses its restraint and generates elastic force to push the locking block 46 into the connecting rod 43, completing its positioning. After the sewage is filtered, open the sludge discharge port. The servo motor 51 is activated, driving the unblocking fan blade 54 to rotate in the sludge discharge port, which helps reduce clogging of the discharge port. By setting up this utility model, pressing the locking block 46 and rotating the filter screen 3 causes it to collide with the flap 47, which can shake off the sludge accumulated on the surface of the filter screen 3. The operation is simple and convenient. Afterwards, rotating the filter screen 3 to reset it, the locking block 46 can automatically insert into the connecting rod 43 under the action of the pressure spring 45 to complete the positioning. The whole process is efficient and can maintain the good filtration performance of the filter screen 3, reducing the problem of reduced filtration efficiency due to sludge accumulation.
