Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of silica processing equipment, specifically a pressure filter device for silica preparation. Background Technology
[0002] Silica is a general term for finely powdered inorganic silicon compounds, mainly composed of hydrated silicon dioxide. It is named for its white appearance and similar physicochemical properties to carbon black. It is an important functional filler in the rubber, plastics, coatings, and ink industries, characterized by high specific surface area, strong adsorption, and excellent reinforcing properties.
[0003] Chinese utility model patent CN218130239U discloses a silica filter press unit, including a filter press body. The upper surface of the filter press body has a filter chamber, and a detachable forming sleeve is installed inside the filter chamber. Both the upper and lower ends of the forming sleeve have openings. A filter plate, adapted to the inner cavity of the forming sleeve, is located near the lower opening of the forming sleeve. An elastic telescopic rod is provided on the lower surface of the filter plate. The end of the elastic telescopic rod away from the filter plate is connected to the bottom of the filter chamber. A driving component is provided inside the filter chamber, and the elastic telescopic rod is driven by the driving component to move the filter plate along the axis of the forming sleeve. After hydraulic filtration, this technical solution drives a locking plate to move horizontally away from the axis of the elastic telescopic rod. At this time, the elastic telescopic rod automatically moves the filter plate upward, causing the filter cake to move out of the forming sleeve, facilitating quick manual removal and improving work efficiency while being convenient to use.
[0004] To filter silica, the aforementioned silica filter press unit is equipped with telescopic devices and pressure plates. However, the silica filter press unit does not have the function of cleaning the pressure plates. The silica filter cake particles are small and may contain residual moisture or surfactants, resulting in strong adhesion between the filter cake and the pressure plate surface. The filter cake is difficult to detach automatically from the pressure plate surface, requiring manual cleaning or high-intensity washing during unloading. This increases the operating burden and equipment wear, and may also lead to an increased filter cake breakage rate and reduced product yield. Utility Model Content
[0005] This invention provides a pressure filter device for preparing silica to solve the problems in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a filter press device for preparing silica, comprising a filter press body, a filter chamber formed in the middle of the top of the filter press body, a forming sleeve inside the filter chamber, a filter plate inside the forming sleeve, a telescopic frame fixedly mounted at the rear of the top of the filter press body, a hydraulic cylinder fixedly mounted at the top of the telescopic frame, a moving plate fixedly mounted at the telescopic end of the hydraulic cylinder, a pressure plate fixedly mounted at the bottom of the moving plate, a vibration motor fixedly mounted on one side of the top of the moving plate, a hammer fixedly mounted on the output shaft of the vibration motor, an mounting plate fixedly mounted on one side of the top of the filter press body, an electric push rod fixedly mounted on one side of the mounting plate, a connecting block fixedly mounted at the telescopic end of the electric push rod, a connecting groove formed on the side of the connecting block away from the electric push rod, a connecting piece movably mounted in the connecting groove, a scraper fixedly mounted on one side of the connecting piece, a threaded hole formed at the top of the connecting block, a fixing bolt movably mounted in the threaded hole, and the connection between the fixing bolt and the connecting piece being a movable insertion.
[0007] Furthermore, the bottom of the filter plate is fixedly connected to the telescopic end of the elastic telescopic rod.
[0008] Furthermore, a threaded sleeve is movably provided on the outside of the bottom of the elastic telescopic rod.
[0009] Furthermore, a contact plate is fixedly provided on the outer wall of the telescopic end of the elastic telescopic rod, and a cam is provided at the bottom of the contact plate.
[0010] Furthermore, one side of the cam is fixedly connected to the output shaft of the drive motor.
[0011] Furthermore, a drain pipe is fixedly installed on one side of the bottom of the filter press chamber.
[0012] Compared with the prior art, the present invention provides a pressure filter device for preparing silica, which has the following advantages:
[0013] 1. The filter press device for preparing silica is equipped with a vibrating motor and a hammer. When the vibrating motor is started, the high-frequency vibration generated by the vibrating motor is transmitted to the pressure plate through the hammer, causing the surface of the pressure plate to vibrate slightly, thereby loosening the contact interface between the filter cake and the pressure plate, making it easier for the filter cake to detach as a whole. This not only helps to reduce the loss of filter cake residue, but also avoids damage to the coating or structure of the pressure plate surface by forced scraping.
[0014] 2. This filter press device for preparing silica uses a connecting block, a connecting piece, and a fixing bolt. By turning the fixing bolt, the bolt rotates within the threaded hole of the connecting block. When one end of the fixing bolt moves out of the connecting piece, the limiting position of the connecting piece is released. This allows the scraper to be pulled out, causing the connecting piece to move out of the connecting groove, thus completing the disassembly of the scraper. The reverse operation allows for installation. This enables quick disassembly and installation of the scraper, greatly facilitating cleaning or replacement of the scraper by workers. It effectively reduces the risk of silica filter cake adhering to the scraper and affecting subsequent scraping effects, extends the service life of the scraper, and helps ensure that the scraper always has strong scraping performance, further improving scraping efficiency and effect.

[0019] 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 protection scope of the present utility model.
[0020] Please see Figure 1-3This utility model discloses a filter press device for preparing silica, including a filter press body 1. A filter press chamber 201 is formed in the middle of the top of the filter press body 1. A forming sleeve 202 is arranged inside the filter press chamber 201, and a filter plate 203 is arranged inside the forming sleeve 202. A telescopic frame 301 is fixedly arranged at the rear of the top of the filter press body 1. A hydraulic cylinder 302 is fixedly arranged at the top of the telescopic frame 301. A moving plate 303 is fixedly arranged at the telescopic end of the hydraulic cylinder 302. A pressure plate 304 is fixedly arranged at the bottom of the moving plate 303. A vibration motor 305 is fixedly arranged on one side of the top of the moving plate 303. A hammer 306 is fixedly mounted on the output shaft of the filter press 1. A mounting plate 307 is fixedly mounted on one side of the top of the filter press body 1. An electric push rod 308 is fixedly mounted on one side of the mounting plate 307. A connecting block 309 is fixedly mounted on the telescopic end of the electric push rod 308. A connecting groove is opened on the side of the connecting block 309 away from the electric push rod 308, and a connecting member 310 is movably mounted in the connecting groove. A scraper 311 is fixedly mounted on one side of the connecting member 310. A threaded hole is opened on the top of the connecting block 309, and a fixing bolt 312 is movably mounted in the threaded hole. The connection relationship between the fixing bolt 312 and the connecting member 310 is a movable insertion.
[0021] Specifically, the bottom of the filter plate 203 is fixedly connected to the telescopic end of the elastic telescopic rod 401.
[0022] In this embodiment, by setting up a filter plate 203 and an elastic telescopic rod 401, after the filter press is completed, the elastic telescopic rod 401 can apply an upward auxiliary force to the filter plate 203 through elasticity, and help push the filter plate 203 to move upward.
[0023] Specifically, a threaded sleeve 402 is movably provided on the bottom of the elastic telescopic rod 401.
[0024] In this embodiment, by setting up the elastic telescopic rod 401 and the threaded sleeve 402, the threaded connection between the elastic telescopic rod 401 and the threaded sleeve 402 greatly facilitates the disassembly of the elastic telescopic rod 401 by the workers, which helps to improve work efficiency and reduce maintenance costs.
[0025] Specifically, a contact plate 403 is fixedly provided on the outer wall of the telescopic end of the elastic telescopic rod 401, and a cam 404 is provided at the bottom of the contact plate 403.
[0026] In this embodiment, by setting up an elastic telescopic rod 401, a contact plate 403, and a cam 404, when the cam 404 rotates, the change in the contour of the cam 404 will push the contact plate 403 to move up and down, and then the contact plate 403 will directly drive the telescopic end of the elastic telescopic rod 401 to make vertical reciprocating motion, thereby achieving the purpose of adjusting the height of the filter plate 203.
[0027] Specifically, one side of the cam 404 is fixedly connected to the output shaft of the drive motor 405.
[0028] In this embodiment, by setting a cam 404 and a drive motor 405, the direct connection structure enables the drive motor 405 to directly adjust the speed, direction and start / stop timing of the cam 404, thereby precisely controlling the movement state of the contact plate 403 and the elastic telescopic rod 401.
[0029] Specifically, a drain pipe 406 is fixedly installed on one side of the bottom of the filter press chamber 201.
[0030] In this embodiment, by setting up a filter press chamber 201 and a drain pipe 406, the liquid in the feed solution seeps out through the filter plate 203 and naturally converges to the bottom of the filter press chamber 201 due to gravity, and is quickly discharged through the drain pipe 406.
[0031] In use, the liquid material is poured into the forming sleeve 202, and the hydraulic cylinder 302 is started. The telescopic end of the hydraulic cylinder 302 drives the moving plate 303 and the pressure plate 304 to move downward, thereby filtering the liquid material with the cooperation of the filter plate 203. The liquid in the material falls into the bottom of the filter chamber 201 through the filter plate 203. Opening the valve allows it to be discharged from the drain pipe 406, while the filter cake is intercepted on the surface of the filter plate 203. The hydraulic cylinder 302 is started again, and the telescopic end of the hydraulic cylinder 302 drives the pressure plate 304 to reset. At the same time, the vibration motor 305 is started, and the vibration motor 305 transmits vibration to the hammer 306, causing the pressure plate 304 to vibrate, which facilitates the removal of the filter cake. After the pressure plate 304 has reset, the drive motor 405 is started. The output shaft of the drive motor 405 drives the cam 404 to rotate, causing the cam 404 to push the contact plate. 403, the telescopic end of the elastic telescopic rod 401 extends outward and drives the filter plate 203 to move upward until the surface of the filter plate 203 is flush with the surface of the filter press body 1. The electric push rod 308 is activated, and the telescopic end of the electric push rod 308 drives the connecting block 309 and the scraper 311 to move, thereby scraping off the filter cake on the surface of the filter plate 203 and collecting it. When the scraper 311 needs to be cleaned or replaced, the fixing bolt 312 is turned. The fixing bolt 312 rotates in the threaded hole of the connecting block 309. When one end of it moves out of the connecting piece 310, the limit of the connecting piece 310 is released. The scraper 311 is pulled out, so that the connecting piece 310 moves out of the connecting groove, completing the disassembly of the scraper 311. The reverse operation can be used for installation, thereby realizing the quick disassembly and installation of the scraper 311, which is convenient for the staff to clean or replace the scraper 311.
[0032] In summary, this filter press device for preparing silica utilizes a vibrating motor 305 and a hammer 306. When the vibrating motor 305 is activated, the high-frequency vibration generated by it is transmitted to the pressure plate 304 via the hammer 306, causing slight vibrations on the surface of the pressure plate 304. This loosens the contact interface between the filter cake and the pressure plate 304, making it easier for the filter cake to detach as a whole. This not only helps reduce filter cake residue loss but also prevents forced scraping that could damage the coating or structure of the pressure plate 304. Furthermore, the device incorporates a connecting block 309, a connector 310, and fixing bolts 312. The fixing bolts 312 are tightened by rotating a knob on the connecting block 309. Rotate within the threaded hole of component 9. When one end moves out of connector 310, the limit of connector 310 is released. Pull the scraper 311 to move connector 310 out of the connecting groove, completing the disassembly of scraper 311. The reverse operation allows for installation, thus achieving quick disassembly and installation of scraper 311. This greatly facilitates the cleaning or replacement of scraper 311 by staff, effectively reducing the risk of silica filter cake adhering to scraper 311 and affecting subsequent scraping effect, extending the service life of scraper 311, and also helping to ensure that scraper 311 always has strong scraping performance, further improving scraping efficiency and effect.
