Technical Field

[0001] This utility model relates to the field of filter press technology, and specifically to a filter plate for filter press that is easy to position and install. Background Technology

[0002] In the chemical production field, o-chloro-p-nitroaniline is an important organic synthesis intermediate widely used in industries such as dyes, pesticides, and pharmaceuticals. With the continuous development of related industries, the demand for o-chloro-p-nitroaniline is increasing, and its production scale is gradually expanding.

[0003] Existing filter presses often have complex structural designs, and the filter plates are usually installed in a relatively compact space inside the equipment. When it is necessary to replace the filter plates, maintenance personnel have difficulty obtaining sufficient operating space, making the removal and installation of filter plates extremely difficult. At the same time, the filter plates are mostly connected by traditional methods such as bolt fastening. After long-term use, due to factors such as material corrosion and pressure, the bolts are prone to rusting and seizing. Disassembly requires a lot of time and effort and may even damage surrounding components. Therefore, a filter plate that is easy to position and install is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a filter plate for a filter press that is easy to position and install, so as to solve the problems mentioned in the background art.

[0006] A filter plate for easy positioning and installation in a filter press includes a filter plate body and a connecting block. The filter plate body has sliding grooves on both sides. One side of the connecting block contacts the outer wall of the filter plate body. The connecting block has a positioning component inside for positioning the filter plate body. The positioning component includes a shaft, the outer wall of which is movably connected to the interior of the connecting block. One end of the shaft is fixedly connected to the positioning block. The filter plate body has a stepped groove inside, and the outer wall of the positioning block contacts the interior of the stepped groove. The connecting block has an impact mechanism inside for installing the filter plate body.

[0007] By adopting the above technical solution, the scheme achieves precise and efficient positioning of the filter plate body by setting up the cooperation of sliding groove, connecting block, insert shaft, positioning block and stepped groove, the combination design of connecting block and filter plate body, and the cooperation of insert shaft, positioning block and stepped groove in positioning component. Insert shaft can move flexibly to drive positioning block to cooperate with stepped groove of filter plate body, ensuring accurate position of filter plate during installation, preventing filter plate from shifting during filtration, and ensuring the accuracy and stability of filtration operation.

[0008] A further improvement of the present invention is that the impact mechanism includes a sliding column, the outer wall of the sliding column is slidably connected to the inside of the connecting block, a positioning rod is inserted into the inside of the sliding column, and one end of the positioning rod extends into the inside of the connecting block.

[0009] By adopting the above technical solution, the cooperation of the sliding column, positioning rod and connecting block is set up. The positioning rod extends into the interior of the connecting block, which increases the stability and reliability of the impact mechanism. During the installation or disassembly of the filter plate, the operation of the impact mechanism can be more convenient. For example, by using the sliding function of the sliding column and the positioning function of the positioning rod, the filter plate can be precisely adjusted and firmly locked. At the same time, it is also easy to disassemble when the filter plate needs to be replaced, which improves the convenience and safety of operation.

[0010] A further improvement of the present invention is that: a fixing block is fixedly connected to the bottom of the sliding column, the outer wall of the fixing block is slidably connected to the inside of the sliding groove, and a fixing column is fixedly connected to the top of the fixing block.

[0011] By adopting the above technical solution, the fixed block, fixed column and sliding groove are set up to cooperate with each other. The fixed column connects the sliding column and support block and other structures, which enhances the stability of the overall structure, helps to evenly distribute the pressure, prevents excessive local stress, and extends the service life of the filter plate and the whole device.

[0012] A further improvement of the present invention is that a support block is fixedly connected to the bottom of the connecting block, and the outer wall of the support block and the inside of the sliding groove are slidably connected.

[0013] The above technical solution provides a stable support for the entire filter plate device by setting up a support block and a sliding groove to cooperate with each other.

[0014] A further improvement of this utility model is that: a circular groove is provided inside the support block, a sliding disk is slidably connected inside the circular groove, and a rubber column is fixedly connected to the top of the sliding disk, and there are several sets of the rubber columns.

[0015] By adopting the above technical solution, the combination of circular grooves and rubber columns, the cooperation between the circular grooves and sliding discs in the support block, and the arrangement of multiple sets of rubber columns, the filter plate body can be impacted during disassembly, and the silt on the outer wall of the filter plate body can be removed, thus improving its practicality.

[0017] By adopting the above technical solution, the first spring, the support block and the sliding disc are set up to cooperate with each other. When the outer wall of the positioning rod is separated from the inside of the sliding column, the fixed column will drive the support block and the rubber column to rise inside the circular groove through the sliding disc. The rubber column will impact the filter plate body, causing the silt adhering to the outer wall of the filter plate to fall off, thus improving the practicality.

[0018] A further improvement of this utility model is that a second spring is fixedly connected to the bottom of the support block.

[0019] By adopting the above technical solution, the support block and the second spring are set up to cooperate with each other. The second spring can buffer the support block, avoid the support block from colliding with the fixed block, and improve the protection.

[0020] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared with the prior art is that the rubber column impacts the filter plate body, causing the silt adhering to the outer wall of the filter plate to fall off, thus improving its practicality.

[0021] This utility model provides a filter plate for easy positioning and installation in a filter press. By setting up a sliding groove, connecting block, insert shaft, positioning block and stepped groove in mutual cooperation, the combination design of the connecting block and the filter plate body, and the cooperation of the insert shaft, positioning block and stepped groove in the positioning component, the filter plate body can be accurately and efficiently positioned. The insert shaft can move flexibly, driving the positioning block to cooperate with the stepped groove of the filter plate body, ensuring that the filter plate is accurately positioned during installation, preventing the filter plate from shifting during the filtration process, and ensuring the accuracy and stability of the filtration operation.

[0022] This utility model provides a filter plate for easy positioning and installation in a filter press. By setting a first spring, a support block and a sliding disc in cooperation, when the outer wall of the positioning rod is separated from the inside of the sliding column, the fixed column will drive the support block and the rubber column to rise inside the circular groove through the sliding disc. The rubber column will impact the filter plate body, causing the sludge adhering to the outer wall of the filter plate to fall off, thus improving its practicality. Attached Figure Description

[0029] The present invention will be further described in detail below with reference to embodiments:

[0030] Example 1

[0031] like Figure 1-5 As shown, this utility model provides a filter plate for easy positioning and installation in a filter press, including a filter plate body 1 and a connecting block 2. Sliding grooves 3 are provided on both sides of the filter plate body 1. One side of the connecting block 2 contacts the outer wall of the filter plate body 1. A positioning component for positioning the filter plate body 1 is provided inside the connecting block 2. The positioning component includes an insert shaft 4, whose outer wall is movably connected to the interior of the connecting block 2. A positioning block 5 is fixedly connected to one end of the insert shaft 4. A stepped groove 6 is provided inside the filter plate body 1, and the outer wall of the positioning block 5 contacts the interior of the stepped groove 6. An impact mechanism for installing the filter plate body 1 is provided inside the connecting block 2. The impact mechanism includes a sliding column 7, whose outer wall is slidably connected to the interior of the connecting block 2. A positioning rod 8 is inserted into the interior of the sliding column 7, and one end of the positioning rod 8 extends into the interior of the connecting block 2.

[0032] In this embodiment, by setting the sliding groove 3, connecting block 2, insert shaft 4, positioning block 5 and stepped groove 6 in mutual cooperation, the combination design of connecting block 2 and filter plate body 1, and the cooperation of insert shaft 4, positioning block 5 and stepped groove 6 in the positioning assembly, the filter plate body 1 can be accurately and efficiently positioned. Insert shaft 4 can move flexibly, driving positioning block 5 to cooperate with stepped groove 6 of filter plate body 1, ensuring that the filter plate is accurately positioned during installation, preventing the filter plate from shifting during the filtration process, and ensuring the accuracy and stability of the filtration operation. By setting the sliding column 7, positioning rod 8 and connecting block 2 in mutual cooperation, positioning rod 8 extends into the interior of connecting block 2, increasing the stability and reliability of the impact mechanism. During the installation or disassembly of the filter plate, the impact mechanism can be operated to achieve more convenient operation. For example, by using the sliding function of sliding column 7 and positioning function of positioning rod 8, the filter plate can be precisely adjusted and firmly locked. At the same time, it is also easy to disassemble when the filter plate needs to be replaced, improving the convenience and safety of operation.

[0033] Example 2

[0034] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, a fixing block 9 is fixedly connected to the bottom of the sliding column 7, the outer wall of the fixing block 9 is slidably connected to the inside of the sliding groove 3, a fixing column 10 is fixedly connected to the top of the fixing block 9, a support block 11 is fixedly connected to the bottom of the connecting block 2, the outer wall of the support block 11 is fixedly connected to the inside of the sliding groove 3, a circular groove 12 is opened inside the support block 11, a sliding disk 13 is slidably connected inside the circular groove 12, a rubber column 14 is fixedly connected to the top of the sliding disk 13, there are several groups of rubber columns 14, a first spring 15 is fixedly connected to the bottom of the sliding disk 13, the bottom of the first spring 15 is fixedly connected to the bottom of the inner wall of the circular groove 12, the outer wall of the fixing column 10 is fixedly connected to the top of the sliding disk 13, the outer wall of the fixing column 10 is slidably connected to the inside of the support block 11, and a second spring 16 is fixedly connected to the bottom of the support block 11.

[0035] In this embodiment, by setting the fixed block 9, the fixed column 10, and the sliding groove 3 in cooperation, the fixed column 10 connects the sliding column 7 and the support block 11, etc., which enhances the stability of the overall structure, helps to evenly distribute pressure, prevents excessive local stress, and extends the service life of the filter plate and the entire device. By setting the support block 11 and the sliding groove 3 in cooperation, the support block 11 at the bottom of the connecting block 2 provides a stable support for the entire filter plate device. At the same time, the fixed connection between the support block 11 and the sliding groove 3 ensures the vertical stability of the filter plate body 1 structure. By setting the circular groove 12, the circular groove 12 and the rubber column 14 in cooperation, the cooperation between the circular groove 12 in the support block 11 and the sliding disk 13, and the multiple sets of rubber columns 14, The design allows for impact on the filter plate body 1 during disassembly, enabling the removal of silt from the outer wall of the filter plate body 1, thus improving practicality. Through the interaction of the first spring 15, the support block 11, and the sliding disc 13, when the outer wall of the positioning rod 8 separates from the interior of the sliding column 7, the fixing column 10 drives the rubber column 14 to rise through the sliding disc 13 within the circular groove 12. The rubber column 14 then impacts the filter plate body 1, causing the silt adhering to the outer wall of the filter plate to fall off, further improving practicality. Furthermore, the interaction of the support block 11 and the second spring 16 allows the second spring 16 to buffer the support block 11, preventing collisions between the support block 11 and the fixing block 9, thus improving protection.

[0036] The working principle of the filter plate used in this filter press, which is easy to position and install, will be explained in detail below.

[0037] like Figure 1-5 As shown, one side of the connecting block 2 is fixedly connected to the external support. When the filter plate body 1 needs to be disassembled, the user will disengage the outer wall of the positioning rod 8 from the inside of the sliding column 7. At the same time, the sliding column 7 will drive the rubber column 14, the fixed column 10 and the sliding plate 13 to rise inside the circular groove 12 through the elasticity of the first spring 15. The rubber column 14 will impact the filter plate body 1, causing the sludge adhering to the outer wall of the filter plate to fall off. At the same time, the second spring 16 can buffer the support block 11.

[0038] Then the operator or the corresponding disassembly device will apply a reverse force to the insertion shaft 4. This force will cause the insertion shaft 4 to move away from the stepped groove 6. Since the positioning block 5 is fixedly connected to one end of the insertion shaft 4, when the insertion shaft 4 starts to move, the positioning block 5 will exit from the stepped groove 6. Then the user can manually remove the filter plate body 1 for maintenance and replacement.

[0039] Then the user presses the sliding column 7, which will cause the fixed block 9, fixed column 10, first spring 15, sliding disk 13 and rubber column 14 to descend inside the circular groove 12. When the sliding column 7 slides to the desired position, the user inserts the positioning rod 8 into the inside of the sliding column 7 to restore the impact mechanism to the initial position.

[0040] Then the user pushes the insertion shaft 4 to move the positioning block 5 toward the stepped groove 6 of the filter plate body 1. Once the positioning block 5 contacts the stepped groove 6, due to the unique stepped structure of the stepped groove 6, the positioning block 5 will begin to gradually embed itself along the contour of the stepped groove 6. As the insertion shaft 4 continues to advance, the positioning block 5 will contact different stepped surfaces in the stepped groove 6 in turn, and finally fit tightly with the stepped groove 6.

[0041] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
