Technical Field

[0001] This utility model relates to the field of wastewater treatment, specifically a frame-type wastewater treatment device. Background Technology

[0002] Currently, frame filter presses are a commonly used wastewater treatment equipment. They dewater sludge by squeezing it through filter plates, achieving solid-liquid separation. The filter cake after solid-liquid separation has a high degree of dryness. A frame filter press mainly includes a frame, hydraulic cylinder, filter plates, pressing plates, and thrust plates. The hydraulic cylinder pushes the pressing plates to press the filter plates together, forming a closed filtration chamber. Wastewater enters the filter plates through the input pipe and flows into multiple filter plates through the wastewater flow channel formed by splicing multiple filter plates. Solid particles are intercepted, and liquid passes through the filter cloth and is discharged.

[0003] However, during use, some sludge has high viscosity. After the filter plates are separated, the sludge is not completely removed, and sludge remains on the filter plates. The residual sludge will increase the subsequent filtration resistance. Therefore, a frame-type sewage treatment device is proposed to address the above problems. Utility Model Content

A thrust plate is fixedly connected to one end of the frame, and a hydraulic cylinder is fixedly connected to the other end of the frame. A pressing plate is fixedly connected to the output end of the hydraulic cylinder. The multiple filter plates are located between the thrust plate and the pressing plate. A slider is slidably connected to the side of the frame. The side of the frame is a moving component that allows the slider to move along the frame. A support arm is fixedly connected to the side of the slider away from the frame. Multiple inclined nozzles are fixedly connected to the support arm, and hoses are fixedly connected to the ends of the multiple nozzles.

[0006] Preferably, the moving component includes a motor and a lead screw. A support base is fixedly connected to the end of the frame, and a motor is fixedly connected to the support base. The end of the lead screw is rotatably connected to the support base. The output end of the motor and the end of the lead screw are fixedly connected.

[0011] The advantages of this utility model are:

[0012] 1. This utility model, by setting up a slider, support arm, nozzle and hose, allows the slider to slide along the side of the frame under the drive of the moving component, driving the nozzle on the support arm to move synchronously.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Specific implementation examples are given below.

[0023] Please see Figure 1-5 As shown, a frame-type wastewater treatment device includes a frame 11. Multiple filter plates 12 are slidably connected to the frame 11. A thrust plate 13 is fixed to one end of the frame 11, and a hydraulic cylinder 15 is fixed to the other end. A pressure plate 14 is fixed to the output end of the hydraulic cylinder 15. The multiple filter plates 12 are located between the thrust plate 13 and the pressure plate 14. A slider 16 is slidably connected to the side of the frame 11. The side of the frame 11 is a moving component that allows the slider 16 to move along the frame 11. A support arm 17 is fixedly connected to the side of the slider 16 away from the frame 11. A plurality of inclined nozzles 18 are fixedly connected to the support arm 17, and hoses are fixedly connected to the ends of the plurality of nozzles 18. The moving assembly includes a motor 21 and a lead screw 22. A support base is fixedly connected to the end of the frame 11. The motor 21 is fixedly connected to the support base. The end of the lead screw 22 is rotatably connected to the support base. The output end of the motor 21 and the end of the lead screw 22 are fixedly connected. The lead screw 22 passes through the slider 16 and is connected to the slider 16 through a ball screw nut pair.

[0024] During operation, the hydraulic cylinder 15 pushes the clamping plate 14 to press the filter plates 12 together, forming a sealed filtration chamber. Wastewater enters the filter plates 12 through the input pipe and flows into the filter plates 12 through the wastewater flow channel formed by the splicing of multiple filter plates 12. Solid particles are intercepted, and liquid is discharged through the filter cloth. Water passes through the drain port at the lower end of the filter plates 12. After filtration is completed, the hydraulic cylinder 15 retracts, the clamping plate 14 moves back, the filter plates 12 are released, and then each filter plate 12 is pulled apart for unloading. At this time, the slider 16 slides along the side of the frame 11 under the drive of the moving component, driving the support arm. The nozzles 18 on 17 move synchronously, and the high-pressure cleaning fluid is delivered to the nozzles 18 through the hose to rinse the residual sludge on the surface of the separated filter plate 12. The inclined nozzles 18 spray high-pressure water onto the surface of the filter plate 12. By relying on the flushing of the high-pressure water flow, the clogging particles are effectively removed and the filter pressure resistance is reduced. The moving component includes a motor 21 and a lead screw 22. The motor 21 drives the lead screw 22 to rotate. The lead screw 22 and the slider 16 are connected by a ball screw nut pair. The rotation of the lead screw 22 drives the slider 16 to verify the transverse movement of the frame 11.

[0025] Furthermore, such as Figure 1-5 As shown, the top of the slider 16 is provided with a groove 32, and a pull arm 31 is hinged inside the groove 32. A torsion spring is installed at the hinge of the pull arm 31 and the groove 32. A rod 33 is fixed to the side of the filter plate 12.

[0026] In use, the top of the slider 16 is provided with a groove 32. The pull arm 31, which is hinged in the groove 32, automatically springs up under the action of the torsion spring. When the slider 16 moves with the lead screw 22, the front end of the pull arm 31 contacts the rod 33 on the side of the filter plate 12 and gradually hooks it, thereby driving the filter plate 12 to move synchronously and realize automatic opening, so as to facilitate the separation of the filter plates 12 piece by piece and improve the unloading efficiency.

[0027] Furthermore, such as Figure 1-5 As shown, a support 41 is fixedly connected to the end of the frame 11 away from the support base. A pressure roller 42 is rotatably connected to the top of the support 41. A sleeve 43 is fixedly connected to the side of the groove 32 near the support 41. A locking rod 44 is slidably connected to the middle of the sleeve 43. A locking groove 45 is opened at the end of the pull arm 31 and at the corresponding position of the locking rod 44. A piston 52 is slidably connected inside the piston 52 cavity. The locking rod 44 passes through the piston 52 and is fixedly connected to it. A through hole 53 is opened on the piston 52. A spring 51 is fixedly connected between the end of the locking rod 44 and the sleeve 43.

[0028] After the slider 16 unloads the last filter plate 12, it continues to move until it reaches the support 41. Under the action of the pressure roller 42, the pull arm 31 retracts into the groove 32, and the slot 45 at the end of the pull arm 31 aligns with the locking rod 44. With continued movement, the locking rod 44 engages in the slot 45, thus fixing the pull arm 31 and preventing it from springing upwards. Then, the slider 16 resets to its initial position, and the locking rod 44 is pulled by the spring 51. The lever 44 is pulled out of the slot 45 by the movement of the lever 44, and the pull arm 31 springs up. A piston 52 is installed on the lever 44 and slides in the piston 52 cavity. The two sides of the piston 52 are filled with viscous liquid. When the piston 52 moves, the viscous liquid flows through the through hole 53. Since the diameter of the through hole 53 is limited, the time for the lever 44 to be pulled back by the spring 51 is greatly extended, thereby effectively preventing the slider 16 from hitting the rod 33 above due to the sudden springing of the pull arm 31 during the rapid reset process.

[0029] Furthermore, such as Figure 1-5 As shown, a pulley 6 is rotatably connected to the rod 33. In use, the pulley 6 is rotatably connected to the rod 33. The pulley 6 is used to reduce the frictional resistance between the rod 33 and the pull arm 31, so that the pull arm 31 can pass through the bottom of the rod 33 more smoothly.

[0030] Working principle: During use, hydraulic cylinder 15 pushes clamping plate 14 to press filter plates 12 together, forming a sealed filtration chamber. Wastewater enters filter plates 12 through the input pipe and flows into multiple filter plates 12 through the wastewater flow channel formed by the splicing of multiple filter plates 12. Solid particles are intercepted, and liquid passes through the filter cloth and is discharged. After filtration is completed, hydraulic cylinder 15 retracts, clamping plate 14 retracts, filter plates 12 are released, and then each filter plate 12 is pulled apart for unloading.

[0031] At this time, the slider 16 slides along the side of the frame 11 under the drive of the moving component, which drives the nozzle 18 on the support arm 17 to move synchronously. The high-pressure cleaning fluid is delivered to the nozzle 18 through the hose to rinse the residual sludge on the surface of the separated filter plate 12. The inclined nozzle 18 sprays high-pressure water onto the surface of the filter plate 12. By relying on the flushing of the high-pressure water, the clogging particles are effectively removed and the pressure filter resistance is reduced.

[0032] The moving component includes a motor 21 and a lead screw 22. The motor 21 drives the lead screw 22 to rotate. The lead screw 22 and the slider 16 are connected by a ball screw nut pair. The rotation of the lead screw 22 drives the slider 16 to verify the transverse movement of the frame 11.

[0033] In use, the top of the slider 16 is provided with a groove 32. The pull arm 31, which is hinged in the groove 32, automatically springs up under the action of the torsion spring. When the slider 16 moves with the lead screw 22, the front end of the pull arm 31 contacts the rod 33 on the side of the filter plate 12 and gradually hooks it, thereby driving the filter plate 12 to move synchronously and realize automatic opening, so as to facilitate the separation of the filter plates 12 piece by piece and improve the unloading efficiency.

[0034] After the slider 16 unloads the last filter plate 12, it continues to move until it reaches the support 41. The pull arm 31, under the action of the pressure roller 42, retracts into the groove 32, and the slot 45 at the end of the pull arm 31 aligns with the locking rod 44. With continued movement, the locking rod 44 engages in the slot 45, thus fixing the pull arm 31 and preventing it from springing upwards. Then, the slider 16 resets to its initial position. The spring 51 pulls the locking rod 44, causing it to move out of the slot 45, and the pull arm 31 springs upwards. A piston 52 is installed on the top and slides inside the piston 52 cavity. The piston 52 is filled with viscous liquid on both sides. When the piston 52 moves, the viscous liquid flows through the through hole 53. Since the diameter of the through hole 53 is limited, the time for the locking rod 44 to be pulled back by the spring 51 is greatly extended, thereby effectively preventing the slider 16 from hitting the rod 33 above due to the sudden bounce of the pull arm 31 during the rapid reset process. In use, a pulley 6 is rotatably connected to the rod 33. The pulley 6 is used to reduce the frictional resistance between the rod 33 and the pull arm 31, so that the pull arm 31 can pass through the bottom of the rod 33 more smoothly.
