Description

Technical Field

[0001] The invention relates to the technical field of solid-liquid separation equipment for sewage treatment, and in particular to a remote desludging device for a plate and frame filter press. Background Art

[0002] During the desludging process of plate and frame filter presses in the sewage treatment industry, mud often clings to the filter cloth, requiring manual removal of the mud, which then falls into a screw conveyor and is then transported to the silo. Desludging workshops are typically operated in a closed environment to prevent dust and odor from escaping. This approach can lead to the following problems:

[0003] First, manual operation is labor-intensive, and prolonged operation may lead to negligence during the operation and cause safety accidents.

[0004] Secondly, temperatures that are too high or too low in a closed environment will increase operator fatigue and further increase the probability of safety accidents.

[0005] Third, during the peeling process, dust and irritating odors will be inhaled into the human body, affecting health. Summary of the Invention

[0006] The object of the present invention is to provide a remote desludging device for a plate and frame filter press, which can realize remote desludging operation, reduce labor intensity and safety hazards, and reduce or avoid physical harm to operators caused by the external environment.

[0007] To achieve the above-mentioned object, a remote desludging device for a plate and frame filter press is provided, which is arranged on the crossbeam of the plate and frame filter press and includes a unit frame arranged on the crossbeam, a remote control terminal, and a controller; the unit frame includes a fixed installation frame and a mobile installation frame; the remote control terminal and the controller are remotely connected in communication;

[0008] The fixed installation frame is a door-type frame, the bottoms of the supporting legs on both sides of the frame filter press are respectively slidably connected to the crossbeams on both sides of the frame filter press, and the movable installation frame is arranged on the fixed installation frame and is located above the filter plate of the frame filter press;

[0009] The mobile mounting frame includes a telescopic rod assembly and a camera. The upper end of the telescopic rod assembly is fixed to the fixed mounting frame. A cleaning cross bar is fixed to the lower end of the telescopic rod assembly. The camera is arranged at the lower end of the telescopic rod assembly and above the cleaning cross bar. A plurality of horizontally arranged blowing nozzles are provided on the side of the cleaning cross bar. A plurality of horizontally arranged stripping fingers are provided on the side of the cleaning cross bar. The blowing nozzles are located above the stripping fingers. The blowing nozzles are connected to a gas solenoid valve through a hose. The camera and the gas solenoid valve are electrically connected to a controller.

[0010] The unit frames are provided with two groups and are arranged in parallel. The fixed mounting frames of the two groups of unit frames are connected by a plurality of connecting rods. The ends of the two fixed mounting frames on the crossbeam are connected by a sliding limit rod. The sliding limit rod is slidably connected to the crossbeam. The sliding limit rod is provided with two groups of spaced apart electric telescopic rods. When adjacent filter plates are tightened, a gap is left between their ear plates for inserting the electric telescopic rods. The electric telescopic rods are electrically connected to the controller.

[0011] A moving wheel and a moving wheel driving motor are provided at the bottom of the sliding limit rod, a plurality of regularly distributed magnets are provided on the crossbeam, a Hall sensor is provided on the sliding limit rod, and the Hall sensor and the moving wheel driving motor are electrically connected to the controller.

[0012] Furthermore, the stripping finger is a rubber stripping finger, and a vibration motor is provided at the inner end of the rubber stripping finger, and the vibration motor is electrically connected to the controller.

[0013] Furthermore, the blowing nozzle is a flat nozzle and the spraying direction is obliquely downward.

[0014] Principles and advantages:

[0015] 1. The camera and remote control terminal allow operators to monitor the equipment's operation in real time. They can also operate the stripping device (the air blowing nozzle and stripping fingers on the mobile mounting frame) and observe the equipment's operation. This allows operators to work in a comfortable environment away from enclosed operating spaces, thereby ensuring their health.

[0016] 2. During operation, a start control signal is input through the remote control terminal, and a movement control signal is sent to the controller. The controller drives the moving wheels via the moving wheel drive motor. When the Hall sensor detects a magnetic field signal, the wheels stop. Power is supplied to the electric telescopic rod, positioning the end of the rod between the lugs of adjacent filter plates. The moving wheels are then driven in the opposite direction to automatically separate the adjacent filter plates, facilitating subsequent desludging of the filter cloths. The telescopic rod assembly then moves the cleaning crossbar downward, and the stripping device (air nozzle and stripping fingers on the mobile mounting frame) strips the mud from the filter cloths. Once the cleaning device reaches the bottom, the stripping device raises and closes the gas solenoid valve. Once ready, the next filter plate and filter cloth can be stripped. This solution allows the operator to remotely desludify, reduces labor intensity, safety hazards, and minimizes or eliminates physical hazards to the operator from external environmental factors (such as high and low temperatures, dust, and odor).

[0017] 3. The stripping fingers are rubber stripping fingers. A vibration motor is provided at the inner end of the rubber stripping fingers. The air blowing nozzle is a flat air nozzle and the spray direction is set obliquely downward, which can fully strip the mud blocks on the filter cloth and avoid the need for manual secondary operation.

[0022] Example

[0023] A remote desludging device for a plate-frame filter press is installed on the crossbeam 13 of the existing plate-frame filter press. The plate-frame filter press is fully enclosed with a transparent plate, and a screw conveyor is installed under the plate-frame filter press to facilitate the timely transport of the removed mud blocks. This solution is basically as follows Figure 1 、 Figure 2 As shown, the system comprises a unit frame mounted on a crossbeam 13, a remote control terminal, and a controller. The unit frame comprises a fixed mounting frame 1 and a mobile mounting frame. The remote control terminal and controller are connected for remote communication. The remote control terminal is a tablet computer, and the controller is a conventional single-chip microcontroller, such as a STEM32 series, 51 series, or ESP32 microcontroller.

[0024] The fixed installation frame 1 is a door-like frame, and the bottoms of its two side legs are respectively slidably connected to the crossbeams 13 on both sides of the plate and frame filter press. The movable installation frame is arranged on the fixed installation frame 1 and is located above the filter plate 7 of the plate and frame filter press.

[0025] The mobile mounting frame includes a telescopic rod assembly 2 and a camera 3. The upper end of the telescopic rod assembly 2 is fixed on the fixed mounting frame 1, and a cleaning cross bar 5 is fixed to the lower end of the telescopic rod assembly 2. The camera 3 is arranged at the lower end of the telescopic rod assembly 2 and is located above the cleaning cross bar 5. A plurality of horizontally arranged blowing nozzles 4 are provided on the side of the cleaning cross bar 5, and a plurality of horizontally arranged stripping fingers 6 are provided on the side of the cleaning cross bar 5. The blowing nozzle 4 is located above the stripping fingers 6; the blowing nozzle 4 is connected to the gas solenoid valve through a hose; the camera 3 and the gas solenoid valve are electrically connected to the controller; the telescopic rod assembly 2 can adopt a pneumatic telescopic rod (cylinder), an electric telescopic rod 9 or a hydraulic telescopic rod. This solution adopts a pushing cylinder, which is used in conjunction with a solenoid valve and is electrically connected to the controller. The two ends of the cleaning cross bar 5 are respectively provided with an air supply pipe (a hose can be arranged inside it or can replace the hose) and a cable pipe. The air supply pipe and the cable pipe are movably connected to the fixed installation frame 1 through the clamp on the fixed installation frame 1, which plays a limiting role to prevent the cleaning cross bar 5 from rotating and deviating, thereby affecting the mud removal effect.

[0026] like Figure 2 As shown, the unit frames are provided in two sets, arranged in parallel. The fixed mounting frames of the two sets of unit frames are connected by a plurality of connecting rods 14. The ends of the two fixed mounting frames on the crossbeam 13 are connected by a sliding limit rod 11, which is slidably connected to the crossbeam 13. The sliding limit rod 11 is equipped with two sets of spaced electric telescopic rods 9. When adjacent filter plates 7 are closed, a gap is left between the ear plates 8 for the electric telescopic rods 9 to be inserted. The electric telescopic rods 9 are electrically connected to a controller. The electric telescopic rods 9 operate on the same principle as the lifting camera 3, using a combination of a slider, a phase rod, a screw, and a micro-stepping motor. In the initial state, the slider is hidden in the sliding limit rod 11 and does not hinder the movement of the filter plates 7 on the crossbeam 13. When powered, the slider is pushed upward and inserted into the gap left between the ear plates 8 of adjacent filter plates 7 when they are closed.

[0027] A moving wheel 12 and a moving wheel drive motor 10 are provided at the bottom of the sliding limit rod 11. A chute 16 is provided on the inner side of the crossbeam 13, and the moving wheel 12 is disposed within the chute 16. A plurality of regularly distributed magnets 15 are provided on the crossbeam 13. A Hall effect sensor 17 is provided on the sliding limit rod 11. The Hall effect sensor 17 and the moving wheel drive motor 10 are electrically connected to a controller. After filtration, the filter plates 7 of the plate and frame filter press are closely packed together. Therefore, the magnets 15 can be arranged according to the regular distribution of the filter plates 7. This allows the slider to be pushed upward when the electric telescopic rod 9 is energized, inserting into the gap left between the ear plates 8 of adjacent filter plates 7 when they are closed.

[0028] The stripping finger 6 is a rubber stripping finger 6, and a vibration motor is provided at the inner end of the rubber stripping finger 6. The vibration motor is electrically connected to the controller. The air blowing nozzle 4 is a flat air nozzle and the spraying direction is obliquely downward.

[0029] During operation, a start control signal is input through the remote control terminal, and a movement control signal is sent to the controller. The controller drives the moving wheels 12 via the moving wheel drive motor 10. When the Hall sensor 17 detects a magnetic field signal, the moving wheels 12 stop. The electric telescopic rod 9 is energized, positioning its clamping end between the lugs 8 of adjacent filter plates 7. The moving wheels 12 are then driven in the opposite direction, automatically separating the adjacent filter plates 7 and facilitating subsequent desludging of the filter cloth. The telescopic rod assembly 2 then moves the cleaning crossbar 5 downward, and the stripping device (the air nozzle 4 and stripping fingers 6 on the movable mounting frame) strips the mud from the filter cloth. Once the system reaches the bottom, the system raises and closes the gas solenoid valve. Once ready, the next filter plate 7 is stripped of mud. This solution allows the operator to remotely desludify, reduces labor intensity and safety hazards, and minimizes or eliminates physical hazards to the operator from external environmental factors (such as high or low temperatures, dust, and odor).
