Description

Technical Field

[0001] This utility model relates to the technical field of dehydrator equipment, specifically a multi-functional high-pressure flushing plate and frame automatic dehydrator. Background Technology

[0002] The automatic plate and frame filter press dewatering machine is an automated device used in the field of solid-liquid separation. It is mainly suitable for dewatering filter cakes from filtration equipment such as plate and frame filter presses. Through automated operation, it improves dewatering efficiency and reduces labor costs. It further dewaters the filter cakes formed after filtration by the plate and frame filter press by removing residual moisture from the filter cakes through mechanical extrusion, blowing, and other methods, thereby increasing the solid content of the filter cakes.

[0003] The multi-functional high-pressure flushing plate and frame automatic dewatering machine is a high-efficiency solid-liquid separation device developed from the traditional plate and frame filter press. It is mainly used for dewatering materials such as sludge and slurry. It has multiple functions and significant advantages. It is usually composed of a frame, filter plates, filter cloth, hydraulic system, automatic control system, feeding device, and high-pressure flushing device. The frame supports the entire equipment. The filter plates and filter cloth are the key components for solid-liquid separation. They are arranged alternately to form the filtration chamber. The hydraulic system provides power for pressing and releasing the plate and frame. The automatic control system realizes the automated operation of the equipment. The feeding device transports the material to be processed into the plate and frame. The high-pressure flushing device is used to clean the filter cloth.

[0004] Existing high-pressure flushing plate and frame automatic dewatering machines typically move the filter plates on the equipment after dewatering the filter cake multiple times, causing the filter cake on the filter plates to fall off automatically. However, during the natural falling process, a small amount of residue will still fall onto the filter plates, requiring staff to use cleaning equipment to flush the filter plates a second time. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a multi-functional high-pressure flushing plate and frame automatic dewatering machine to solve the technical problems mentioned in the background art.

[0007] By adopting the above technical solution, the surface of the filter plate is cleaned from top to bottom through the setting of the limiting plate, which greatly reduces the residue of filter cake on the surface of the filter plate and improves the work efficiency of the staff to perform secondary cleaning of the equipment. By setting the positioning plate and spring, the positioning plate and spring are set at one end of the ball to limit the position of the ball and make the ball fit against the filter plate to clean the impurities on the surface of the filter plate. This improves the work efficiency of the limiting plate in scraping off the filter cake residue and enhances the practicality of the device.

[0008] The present invention is further configured such that the two ends of the support frame are provided with grooves, and the top of the device housing is provided with a slide rail, and the slide rail engages with the grooves.

[0013] Preferably, the spring limits the position of the ball, and the spring is fixedly connected to the inner wall of the limiting plate, which also makes the ball fit against the filter plate.

[0014] The present invention is further configured such that the support frame is U-shaped, and an electric push rod is installed at the center point of the support frame.

[0015] Preferably, an electric push rod is installed on the top of the support frame to improve the stability at the contact point between the electric push rod and the limiting plate, and to reduce the tilt and offset of the limiting plate angle.

[0016] The present invention is further configured such that fixing blocks are installed at both ends of the electric push rod, and the fixing blocks are fixedly connected to the outer wall of the support frame.

[0017] Preferably, fixing blocks are added to both ends of the support frame to limit the position of the limiting plate.

[0018] The present invention is further configured such that a magnetic block is provided at the bottom of the fixing block, and the magnetic block engages with the circular hole.

[0019] Preferably, the magnetic block is located inside the circular hole to effectively support the position of the limiting plate.

[0020] The present invention is further configured such that the circular hole is disposed opposite to the fixing block, and a metal layer is disposed inside the circular hole.

[0021] Preferably, reducing the shaking of the limiting plate in a stationary state improves the stability of the device during secondary operations.

[0022] In summary, the present invention has the following main advantages:

[0023] 1. This utility model uses a limiting plate to clean the surface of the filter plate from top to bottom, greatly reducing the residue of filter cake on the surface of the filter plate and improving the efficiency of secondary cleaning of the equipment by the staff.

[0024] 2. This utility model uses a positioning plate and a spring. The positioning plate and spring are set at one end of the ball to limit the position of the ball, which also makes the ball fit against the filter plate to clean the impurities on the surface of the filter plate.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] The embodiments of this utility model will be described below based on its overall structure.

[0033] First embodiment:

[0034] Please see Figures 1-4The device includes a housing 1, with a support frame 2 on the outer wall of the housing 1. An electric push rod 21 is mounted on the top of the support frame 2, and a limiting plate 22 is installed at the bottom of the electric push rod 21. Several sets of ball bearings 220 are mounted at both ends of the limiting plate 22. A positioning plate 222 is mounted at one end of each ball bearing 220, and a spring 223 is mounted at the other end of the positioning plate 222. Circular holes 221 are provided at both ends of the support frame 2. The limiting plate 22 allows for top-to-bottom cleaning of the filter plate surface, significantly reducing filter cake residue and improving the efficiency of secondary cleaning. The positioning plate 222 and spring 223 limit the position of the ball bearings 220, ensuring they adhere to the filter plate and effectively clean impurities from the filter plate surface. This improves the efficiency of the limiting plate 22 in removing filter cake residue and enhances the practicality of the device.

[0035] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-3 The support frame 2 has grooves 20 at both ends, and the top of the device housing 1 has a slide rail. The slide rail engages with the grooves 20, which improves the stability of the support frame 2 during movement and effectively improves the stability of the limiting plate 22 when it moves downward.

[0036] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 The positioning plate 222 is arc-shaped and is movably sleeved on the inner wall of the limiting plate 22. The positioning plate 222 is in contact with the ball 220 and limits the position of the ball 220, effectively positioning the position of the ball 220.

[0037] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 The end of the spring 223 away from the positioning plate 222 is fixedly connected to the inner wall of the limiting plate 22. The spring 223 limits the position of the ball 220, and the fixed connection between the spring 223 and the inner wall of the limiting plate 22 also makes the ball 220 fit against the filter plate.

[0038] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-3 The support frame 2 is U-shaped, and an electric push rod 21 is installed at the center point of the support frame 2. Installing the electric push rod 21 on the top of the support frame 2 improves the stability when the electric push rod 21 is in contact with the limiting plate 22, and reduces the tilt and offset of the limiting plate 22.

[0039] Second embodiment:

[0040] Please see Figures 1-3The difference between Embodiment 2 and Embodiment 1 is that, while retaining Embodiment 1, fixing blocks 23 are added to both ends of the support frame 2, and the fixing blocks 23 limit the position of the limiting plate 22.

[0041] When the limiting plate 22 is not in use, the fixing block 23 is provided with a magnetic block at one end near the limiting plate 22, and the magnetic block is located in the round hole 221, which effectively supports the position of the limiting plate 22, improves the durability of the electric push rod 21 and the limiting plate 22, thereby reducing the number of times the limiting plate 22 is replaced and reducing the operating cost of the equipment.

[0042] In practical operation, this utility model is as follows:

[0043] When the automatic plate and frame dewatering equipment dewaters the filter cake multiple times and needs to separate the filter cake, a moving component is used to push the filter plates one by one. After pushing the filter plates a certain distance, the impurities on the surface of the filter plates will fall off. At the same time, the support frame 2 is driven by the drive motor to move synchronously with the moving component. When the two sets of filter plates have moved an appropriate distance, the electric push rod 21 drives the limit plate 22 to move towards one end of the filter plate. One end of the ball bearing 220 is equipped with a positioning plate 222 and a spring 223, so that multiple sets of ball bearings 220 contact the surface of the filter plate to clean the impurities on the surface of the filter plate, thereby improving the cleaning efficiency of the equipment.

[0044] Furthermore, the support frame 2 is provided with fixing blocks 23 at both ends, and the bottom of the fixing blocks 23 is provided with magnetic blocks. The magnetic blocks engage with the round holes 221 to limit the position of the limiting plate 22, reduce the shaking of the limiting plate 22 in a static state, and improve the stability of the device in secondary operation.

[0045] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
