Description

Technical Field

[0001] This utility model relates to a cleaning mechanism for the unloading platform of a filter press, belonging to the field of filter presses. Background Technology

[0002] A filter press is a mechanical device that uses a special filter medium to apply pressure to a material, causing the liquid to seep out. It is a commonly used solid-liquid separation device and is still widely used in industries such as chemical, pharmaceutical, metallurgical, dye, food, brewing, ceramics, and environmental protection. The filter plates are stable in performance, easy to operate, safe, and labor-saving. The metal press cylinder is made of seamless steel pipe and precision-cast plastic steel filter plates, which are resistant to high temperature and high pressure, durable, and require an auxiliary cleaning mechanism to clean the unloading platform after the waste material is discharged.

[0003] Chinese patent discloses a discharge device for a plate and frame filter press (publication number: CN 201988245U), which includes a discharge platform, a cake receiving box, a wooden base, and a sludge discharge trough. The discharge platform serves as the working table of the plate and frame filter press, which is placed on the platform. The cake receiving box is located below the discharge port of the plate and frame filter press and rests on the wooden base. Because the discharge platform is directly used as the working table of the plate and frame filter press, and the filter press and discharge platform can be fixed together with anchor bolts, the overall structure of the plate and frame filter press is simplified.

[0004] After the sludge is processed by the filter press and dewatered, it tends to stick to the unloading platform during the feeding process. This requires secondary treatment by the staff, which is not only tedious and inefficient, but also prone to clogging after sticking to the unloading platform. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a cleaning mechanism for the unloading platform of a filter press, so as to solve the problem that after the filter press is processed and the sludge is dewatered, it is easy to stick to the unloading platform during the feeding process, which requires the staff to perform secondary treatment of the sludge. This is not only cumbersome and inefficient, but also prone to clogging after sticking to the unloading platform.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cleaning mechanism for a filter press unloading platform, comprising a frame, a control panel, a filtering device, a pressing device, an unloading platform, an exhaust valve, a limiting groove frame, and a movable loading trolley. The control panel is located at the upper right end of the frame, the filtering device is located at the upper inner side of the frame, the lower right end of the frame is connected to the pressing device, the middle part of the frame is fixed to the unloading platform, the left end of the frame is connected to the exhaust valve, the lower inner side of the frame is fixed to the limiting groove frame, and the inner side of the limiting groove frame is movably fitted with the movable loading trolley. The unloading platform includes a shell, a discharge trough, a base, and a vibration device. The discharge trough is located in the middle of the inner side of the shell, the bottom of the inner side of the shell is fixed to the base, the top of the base is vertically fixed to the vibration device, and the outer side of the shell is fixed to the frame.

[0007] Furthermore, the vibration device includes a housing, a support base, a motor, a lifting device, a fixing block, and a top plate. The bottom inner side of the housing is fixed to the support base. The left and right ends of the top of the support base are respectively fixed to the lifting device and the motor, and the left end of the motor is connected to the lifting device. The upper left end of the lifting device is fixed to the fixing block. The top of the lifting device is fixed to the top plate as a whole. The bottom of the housing is vertically fixed to the base. The top of the top plate is movably fitted to the top of the housing.

[0008] Furthermore, the lifting device includes a rotating shaft, a limiting block, a rotating wheel, a top rod, and a limiting sleeve. The front end of the rotating shaft passes through the middle of the inner side of the limiting block and is fixed to the middle of the rear end of the rotating wheel. The outer side of the rotating wheel is movably fitted with the top rod. The top of the top rod is connected through the limiting sleeve. The rear end of the rotating shaft is fixed to a motor. The top of the top rod is fixed to the top plate as a whole. The front end of the limiting sleeve is fixed to a fixing block.

[0009] Furthermore, two vibration devices are provided at the left and right ends of the inner side of the housing, with the left vibration device fixed to the housing and the bottom end of the right vibration device fixed to the base.

[0010] Furthermore, the top plate is inclined, and a rubber layer is provided on the top of the top plate.

[0011] Furthermore, the rotating wheel is comma-shaped, the outer cross-section of the rotating wheel is polished, and the outer side of the rotating wheel is in close contact with the top rod.

[0012] Advantages: The cleaning mechanism of the filter press unloading platform of this utility model has a vibration device installed inside the shell. The rotating wheel inside the vibration device can drive the top rod to move up and down in the limiting sleeve under the drive of the motor, so that the top plate impacts the inclined surface of the shell, thereby achieving the vibration effect. This avoids sludge adhering to the unloading platform and causing blockage, and also improves the sludge treatment efficiency and reduces the workload of the staff. Attached Figure Description

The outer side of the housing 51 is fixed to the frame 1. The base 53 can increase the working height of the vibration device 54.

[0022] Please see Figure 3 This utility model provides an improved cleaning mechanism for the unloading platform of a filter press. The vibration device 54 includes a housing 541, a support base 542, a motor 543, a lifting device 544, a fixing block 545, and a top plate 546. The bottom inner side of the housing 541 is fixed to the support base 542. The left and right ends of the top of the support base 542 are respectively fixed to the lifting device 544 and the motor 543, and the left end of the motor 543 is connected to the lifting device 544. The upper left end of the lifting device 544 is fixed to the fixing block 545. The top of the lifting device 544 is fixed to the top plate 546 as one piece.

[0023] Please see Figure 4 This utility model provides an improved cleaning mechanism for the unloading platform of a filter press. The lifting device 544 includes a rotating shaft 5441, a limiting block 5442, a rotating wheel 5443, a top rod 5444, and a limiting sleeve 5445. The front end of the rotating shaft 5441 passes through the middle of the inner side of the limiting block 5442 and is fixed to the middle of the rear end of the rotating wheel 5443.

[0024] The work process is as follows:

[0025] First, the staff can place the device horizontally at the location where it is needed, and then connect the external power supply to the device. Then, the staff can start the pressing device 4 through the control panel 2, which will drive the filter device 3 to start working. The exhaust valve 6 can filter the sludge in the filter device 3. After the sludge is processed, it can be discharged to the unloading platform 5, so that the sludge falls into the mobile loading car 8, thereby achieving the collection effect.

[0026] Second, during the process, the staff can start the motor 543 through the control panel 2. The output shaft of the motor 543 will drive the rotating shaft 5441 to rotate, and the comma-shaped wheel 5443 will rotate accordingly. This will cause the top rod 5444 to lift and lower in the limit sleeve 5445. The top plate 546 will impact the inclined surface at the top of the housing 51, thereby cleaning the sludge adhering to the inclined surface. The resulting vibration effect can process the sludge faster and better.
