Description

Technical Field

[0001] This utility model relates to the field of sodium tungstate processing technology, and more specifically, to a pressure filter device for processing sodium tungstate solutions that is easy to clean. Background Technology

[0002] Sodium tungstate is a colorless or white orthorhombic crystal, a lustrous flaky crystal or crystalline powder. Sodium tungstate is soluble in water, and its aqueous solution is slightly alkaline. It is insoluble in ethanol and slightly soluble.

[0003] Sodium tungstate needs to be easily filtered during its preparation. However, existing filter presses are not convenient for internal cleaning, and prolonged use can affect the filtration quality.

[0004] To address the above issues, application number 202221733246.6, entitled "A Filter Press Device for Processing Sodium Tungstate Solution that is Easy to Clean," describes a filter press box. The filter press box has sliding grooves on both sides of its upper part. A pressure plate is connected to one side of the inside of the filter press box, and a support rod is rotatably connected to the middle of the upper end of the pressure plate. In this invention, rotating one of the fixed rods causes the fixed block to rotate. Pulling the fixed rod to one side causes the moving sleeve to move, which in turn moves the moving block. This movement of the fixed rod causes the fixed block to move linearly to one side, removing it from the fixed groove. This decouples the two fixed rods, allowing the rotating plate to be removed for cleaning of the inner wall of the filter press box, preventing the filter press box from being uncleaned for extended periods and affecting the filtration quality.

[0005] Although the device has many beneficial effects, the following problems still exist: When cleaning the inner wall of the filter press, although the device is designed to provide certain conveniences, during the cleaning process, operators often still need to disassemble some parts of the device in order to achieve a complete cleaning of the inner wall of the filter press. This cumbersome operation process not only consumes a lot of time and manpower, but also seriously reduces the cleaning efficiency and cannot meet the needs of efficient operation.

[0006] Furthermore, the extrusion plates used in this device lack an effective self-cleaning mechanism during actual operation. This deficiency forces operators to manually clean the bottom of the extrusion plates after each use to ensure their continued normal operation. Manual cleaning increases the workload of operators, causes numerous inconveniences in actual use, and to some extent limits the overall efficiency of the device.

[0007] In view of this, we propose a pressure filter device for processing sodium tungstate solution that is easy to clean. Utility Model Content

A snap-fit ​​plate is snapped into the inside of the filter press chamber, and a filter plate is fixedly connected inside the snap-fit ​​plate. A limit assembly is installed on the top of the filter press chamber, and multiple limit assemblies include connecting blocks. A support frame and a telescopic water drum hose reel are installed on the outer wall of the filter press chamber. A multi-stage electric push rod is installed on the outer wall of the support frame. The output end of the multi-stage electric push rod is connected to a cleaning assembly, which includes a moving plate. A water storage tank is installed on the outer rear wall of the filter press chamber, and a water inlet is installed on the top of the water storage tank. A water pump is installed on the outer wall of the water tank. The output end of the water pump is connected to a water pipe, which is wound inside the telescopic water drum hose reel. The end of the water pipe passes through the filter press box and connects to the outer wall of the moving plate. A through square opening is provided on the inner wall of the filter press box. A connecting box is also provided on the rear outer wall of the filter press box. A fixed shell is provided on the top of the filter press box. A feed inlet is provided on the front outer wall of the fixed shell. A controller and an ultrasonic generator are provided on the side wall of the fixed shell. A mounting frame is provided on the rear outer wall of the fixed shell. A hydraulic cylinder is provided on the top of the mounting frame.

[0012] Preferably, the inner walls of the plurality of connecting blocks are provided with springs, the ends of the springs are connected to limit plates, and the tops of the plurality of connecting blocks are threaded with threaded rods, the ends of the threaded rods passing through the springs and rotatably connected to the top of the limit plates.

[0013] Preferably, the inner walls of the plurality of connecting blocks are provided with springs, the ends of the springs are connected to limit plates, and the tops of the plurality of connecting blocks are threaded with threaded rods, the ends of the threaded rods passing through the springs and rotatably connected to the top of the limit plates.

[0014] Preferably, the outer wall of the movable plate is provided with fan-shaped nozzles and water spray shells, and multiple fan-shaped nozzles and water spray shells are in communication with the cavity.

[0016] Preferably, the side wall of the push plate is provided with a sealing gasket and an ultrasonic vibration plate, and the outer wall of the push plate is also fixedly connected with a pressing plate by screws.

[0017] 3. Beneficial effects

[0018] Compared with the prior art, the advantages of this utility model are as follows: When cleaning the filter press and filter plates, the multi-stage electric push rod 2 can first drive the sealing baffle to move backward, so that it can move away from the through-hole. Then, the water pump and the multi-stage electric push rod 1 can be started. The multi-stage electric push rod 1 can drive the moving plate to move slowly. Then, through the continuous water supply of the water pump, water can be sprayed to multiple fan-shaped nozzles and water spray shells through the water pipe. Then, in conjunction with the movement of the moving plate, the inner wall of the filter press is flushed and cleaned with water. The water sprayed in the water spray shell can pass through the filter plate during the movement of the moving plate, and then use the backflow effect of the water flow to flush the top of the filter plate. The impurities on the top of the filter plate can be flushed and flow into the connecting box, and finally discharged from the drain pipe. The water inside the filter press after cleaning can be discharged through the drain valve. Compared with the existing cleaning methods, this device can clean the inside of the filter press and filter plates without disassembly, which greatly improves the cleaning efficiency of the filter press device.

[0019] After the filter press is completed, the continuous vibration of the ultrasonic vibrating plate can act on the bottom of the extrusion plate, thereby generating a high-frequency oscillation force. This oscillation force can effectively destroy the adhesion between impurities and the extrusion plate, making it difficult for impurities to adhere to the bottom of the extrusion plate. This significantly reduces the amount of impurities, greatly reduces the frequency of manual cleaning of the bottom of the extrusion plate by operators, effectively reduces the workload of operators, solves many problems caused by manual cleaning, and further improves the practicality and overall efficiency of the device.

[0030] Please see Figure 1-6 This utility model provides a technical solution:

[0031] A filter press device for processing sodium tungstate solution that is easy to clean includes a filter press box 100. A drain valve 101 is provided on the outer wall of the front of the filter press box 100. A snap-fit ​​plate 110 is snapped into the inside of the filter press box 100. A filter plate 111 is fixedly connected inside the snap-fit ​​plate 110. A limit component is provided on the top of the filter press box 100. Multiple limit components include connecting blocks 120. A support frame 130 and a telescopic water drum hose reel 150 are provided on the outer wall of the filter press box 100.

[0032] In some embodiments, the telescopic water hose reel model 150 can use the Greenburg GS100A water hose reel, which is existing technology and facilitates the extension and retraction of water hoses, allowing for more flexible changes in conjunction with the drive of the moving plate 132.

[0033] The outer wall of the support frame 130 is provided with a multi-stage electric push rod 131. The output end of the multi-stage electric push rod 131 is connected to a cleaning component. The cleaning component includes a moving plate 132. A water storage tank 200 is provided on the outer wall behind the filter press 100. A water inlet 210 is provided on the top of the water storage tank 200. A water pump 220 is provided on the outer wall of the water storage tank 200.

[0034] In some embodiments, the water pump 220 may be a commercially available model, which facilitates the delivery of water.

[0035] A water pipe is connected to the output end of the water pump 220. The water pipe is wound inside the telescopic water drum hose reel 150. The end of the water pipe passes through the filter press box 100 and is connected to the outer wall of the moving plate 132. A through square opening 140 is opened on the inner wall of the filter press box 100. A connecting box 160 is also provided on the rear outer wall of the filter press box 100. A fixed shell 300 is provided on the top of the filter press box 100. A feed inlet 310 is provided on the front outer wall of the fixed shell 300. A controller 320 and an ultrasonic generator 330 are provided on the side wall of the fixed shell 300. A mounting bracket 340 is provided on the rear outer wall of the fixed shell 300. A hydraulic cylinder 350 is provided on the top of the mounting bracket 340. A pressing assembly is connected to the output end of the hydraulic cylinder 350. The pressing assembly includes a push plate 360.

[0036] In some embodiments: the ultrasonic generator 330 and the ultrasonic vibrating plate 362 are prior art, facilitating vibration of the extrusion plate 363. The ultrasonic generator 330 generally includes a power module, an oscillator, a power amplifier, a matching circuit, a transducer, and a control circuit. Its principle is that the power module provides a stable DC power supply, the oscillator generates a high-frequency oscillation signal, the power amplifier amplifies the signal, the matching circuit adjusts the impedance matching, and the control circuit monitors and adjusts the parameters in real time. Finally, the electrical signal is converted into ultrasonic waves through the inverse piezoelectric effect of the transducer. The ultrasonic vibrating plate 362 is mainly composed of an ultrasonic transducer, a stainless steel plate sealed housing, etc. Its principle is that the ultrasonic generator outputs high-frequency electrical energy, which is converted into mechanical vibration through the piezoelectric effect of the transducer, causing the vibrating plate to generate high-frequency vibration. The outer wall of the vibrating plate is attached to the inner wall of the extrusion plate 363, thereby facilitating vibration of the extrusion plate 363. All of the above are prior art, and common models on the market can be used.

[0037] Specifically, multiple connecting blocks 120 have springs 121 on their inner walls, and the ends of the springs 121 are connected to limit plates 122. The tops of the multiple connecting blocks 120 are threaded with threaded rods 123. The ends of the threaded rods 123 pass through the springs 121 and are rotatably connected to the top of the limit plates 122, which facilitates the limiting of the snap-fit ​​plate 110.

[0038] In some embodiments, when the snap-fit ​​plate 110 needs to be replaced, simply rotate the loosening threaded rod 123. At this time, the spring can drive the limiting plate 122 to retract and move upward, thereby releasing the limiting of the snap-fit ​​plate 110. The reverse operation is performed during installation, making it easier to replace the filter plate 111.

[0039] Furthermore, the movable plate 132 has a cavity 133 inside, and the end of the water pipe extends into the cavity 133. The outer wall of the movable plate 132 is also provided with a cleaning rubber plate 136, which facilitates the cleaning of the inner wall of the filter press box 100 in conjunction with the flushing of the water source.

[0040] Furthermore, the outer wall of the movable plate 132 is provided with fan-shaped nozzles 134 and water spray shells 135, and multiple fan-shaped nozzles 134 and water spray shells 135 are connected to the cavity 133.

[0041] Furthermore, the outer wall of the connecting box 160 is provided with a multi-stage electric push rod 161. The output end of the multi-stage electric push rod 161 is connected to a sealing baffle 162 that matches the through square opening 140. A drain pipe 163 is also provided on one side of the outer wall of the connecting box 160, so that the through square opening 140 can be sealed by the sealing baffle 162 when not being cleaned, thus avoiding any impact on the filter press.

[0042] It is worth noting that the side wall of the push plate 360 ​​is provided with a sealing gasket 361 and an ultrasonic vibration plate 362. The outer wall of the push plate 360 ​​is also fixedly connected with a squeezing plate 363 by screws, which facilitates the squeezing of the sodium tungstate solution, thereby realizing the pressure filtration operation.

[0043] In some embodiments, the device can be powered by an external conventional power source, and the device can be controlled by the controller 330. All of the above are existing technologies.

[0044] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0045] Working Principle: When cleaning the filter press 100 and filter plates 111 is required, the sealing baffle 162 is first moved backward by the multi-stage electric push rod 161, moving it away from the through-hole 140. Then, the water pump 220 and the multi-stage electric push rod 131 are started. The multi-stage electric push rod 131 can drive the moving plate 132 to move slowly. Then, through the continuous water supply from the water pump 220, water is sprayed onto multiple fan-shaped nozzles 134 and the spray shell 135 through the water pipe. Then, in conjunction with the movement of the moving plate 132, the inner wall of the filter press 100 is flushed and cleaned with water. The water sprayed in the spray shell 135 passes through the filter plates 111 during the movement of the moving plate 132, and the backwash effect of the water flow flushes the top of the filter plates 111. The impurities on the top of the filter plates 111 are flushed away and flow into the connecting box. In step 160, the water is finally discharged through drain pipe 163, while the water used for cleaning inside the filter press 100 can be discharged through drain valve 101. Compared with existing cleaning methods, this device can clean the inside of the filter press 100 and the filter plate 111 without disassembly, greatly improving the cleaning efficiency of the filter press device. After the filter press is completed, the continuous vibration of the ultrasonic vibration plate 362 can act on the bottom of the extrusion plate 363, thereby generating a high-frequency oscillation force. This oscillation force can effectively destroy the adhesion between impurities and the extrusion plate 363, making it difficult for impurities to adhere to the bottom of the extrusion plate 363, thus significantly reducing the amount of impurities attached. This greatly reduces the frequency of manual cleaning of the bottom of the extrusion plate 363 by operators, effectively reducing the workload of operators, solving many problems caused by manual cleaning, and further improving the practicality and overall efficiency of the device.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
