Description

Technical Field

[0001] This utility model relates to the field of chemical equipment, and in particular to a device for quickly filling filter plates and filter cloths of a rotary drum filter press. Background Technology

[0002] Currently, rotary drum filter presses are important equipment for fluorination reactions. Through mechanical pressure and specific filter media, they efficiently separate solid particles from liquid in suspension, ultimately obtaining filter cake with low water content and clear filtrate.

[0003] The filtration section includes a rotating filter drum, filter plates, filter cloth, distribution valve, and pressing mechanism. The filter plates have circumferentially recessed grooves extending from the edges towards the center. PTFE-graphite packing is installed within these grooves. The filter cloth is positioned between the inner wall of the grooves and the PTFE-graphite packing, covering the surface of the filter plates. The PTFE-graphite packing compresses the filter cloth, together forming the filtration medium. The distribution valve enables zoned control of the fluid flow path. The pressing mechanism includes squeeze rollers or air bladders. The rotating filter drum drives the filter plates and filter cloth to operate continuously. Solids in the slurry are trapped on the filter plate surface by the filter cloth, forming a filter cake. The distribution valve switches the flow path, allowing the filter cake to undergo pre-dehydration sequentially. Then, the pressing mechanism mechanically reduces the moisture content, ultimately achieving solid-liquid separation.

[0004] Regarding the aforementioned technologies, after the filter plates of a rotary drum filter press, which have been filled with filter cloth, are used, the filter cloth becomes worn, affecting the filtration effect of the filter plate and requiring manual replacement. However, due to factors such as personnel skills, environment, and labor intensity, manual replacement is difficult to achieve high-quality filling and is not conducive to improving the filter cloth filling efficiency. Utility Model Content

[0005] To improve filter cloth filling efficiency, this application provides a device for quickly filling filter cloth onto the filter plates of a rotary drum filter press.

[0006] This application provides a device for quickly filling filter plates and filter cloths of a rotary drum filter press, which adopts the following technical solution: A device for quickly filling filter plates and filter cloths for a rotary drum filter press includes a base, on which a middle plate and a cover plate are mounted. The middle plate and the cover plate are parallel to the base and are located between the cover plate and the base. The filter plate is placed between the middle plate and the cover plate. A bolt is threadedly connected between the middle plate and the cover plate and passes through the middle plate and the cover plate and is inserted into the base. Nuts are threadedly connected to both ends of the bolts and abut against the base and the cover plate, respectively. Several driving components are circumferentially mounted on the upper end of the base. An extrusion plate is connected to the output end of the driving components. The extrusion plate is located between the cover plate and the middle plate and is directly opposite the PTFE graphite packing.

[0007] By adopting the above technical solution, bolts align the intermediate plate and cover plate with the base. The base clamps and fixes the intermediate plate and cover plate with two nuts, thereby enabling the intermediate plate and cover plate to support and fix the filter plate, improving the installation stability of the filter plate. The driving component drives the extrusion plate to approach and push the PTFE graphite packing. The intermediate plate and cover plate guide and limit the extrusion plate. The driving component and the filter plate work together to press and fix the PTFE graphite packing, thereby making the PTFE graphite packing press the filter cloth tightly. Finally, the filter cloth is tightly attached to the filter plate, completing the filter cloth filling, which helps to improve the efficiency of the filter cloth device.

[0008] Optionally, the driving component includes a jack and a mounting plate. The mounting plate is installed on the upper end of the base, and the jack is located between the mounting plate and the filter plate, and is connected to the side of the extrusion plate away from the filter plate.

[0009] By adopting the above technical solution, the base fixes and supports the jack through the mounting plate, and the jack drives the squeezing plate to move closer to or away from the filter plate, which helps to improve the stability of the device operation.

[0010] Optionally, the extrusion plate includes two pressure plates, which are distributed on both sides along the length of the base. The side of the pressure plate away from the filter plate is fixedly connected to the output end of the jack, and the side of the pressure plate closer to the filter plate is directly opposite the groove.

[0011] By adopting the above technical solution, the jack pushes the pressure plate one closer to or away from the filter plate, so that the pressure plate one is closer to or away from the corresponding PTFE graphite packing. When the pressure plate one is close to the PTFE graphite packing, it cooperates with the aluminum plate to press and fix the servo graphite packing, so that the PTFE graphite packing clamps the filter cloth, so that the filter cloth and the inner wall of the groove are in contact with the surface of the filter plate, thereby pressing and fixing the filter cloth, and thus completing the filling of the filter cloth, which is beneficial to improving the stability and convenience of filter cloth installation.

[0012] Optionally, the extrusion plate further includes two pressure plates, which are distributed on both sides along the width direction of the base. The side of the pressure plate away from the filter plate is fixedly connected to the output end of the jack, and the side of the pressure plate closer to the filter plate is directly opposite the groove.

[0013] By adopting the above technical solution, the jack pushes the pressure plate two closer to or away from the filter plate, thereby making the pressure plate two closer to or away from the corresponding PTFE graphite packing. When the pressure plate two is close to the PTFE graphite packing, it cooperates with the filter plate to press the PTFE graphite packing, thereby making the filter cloth adhere to the inner wall of the groove and the surface of the filter plate, thus fixing the filter cloth and completing the filling of the filter cloth, which is beneficial to improving the stability and convenience of filter cloth installation.

[0014] Optionally, the pressure plate includes a horizontal plate and two vertical plates. The vertical plates are located at both ends of the horizontal plate along its length and are perpendicular to the horizontal plate. The end of the vertical plate away from the horizontal plate has an inclined surface. The inclined surface slopes from both ends of the horizontal plate toward the middle of the horizontal plate. Both the horizontal plate and the vertical plate are directly opposite the groove.

[0015] By adopting the above technical solution, when the pressure plate 2 approaches the filter plate, the vertical plate slides to the side of the filter plate through the inclined surface and contacts the PTFE graphite disks located on both sides of the filter plate in the length direction. The two vertical plates clamp the PTFE graphite packings on both sides respectively, thereby making the horizontal plate clamp and fix the PTFE graphite packings facing each other, further improving the installation stability of the PTFE graphite packings, and thus improving the installation stability of the filter cloth.

[0016] Optionally, the intermediate plate and the cover plate are provided with clearance grooves on both sides along the width direction, which are directly opposite the jack. The clearance grooves are recessed from the edge of the base towards the middle of the base.

[0017] By adopting the above technical solution, the clearance groove provides the jack with lateral movement space, reducing the probability of the jack output end touching the base and affecting the operation of the device, which is conducive to improving the convenience and stability of the device operation.

[0018] Optionally, the mounting plate includes a fixed plate and two baffles. The fixed plate is perpendicular to the base, and the two baffles are connected to both sides of the mounting plate along the lateral direction and are perpendicular to the fixed plate. The fixed plate and the mounting plate form a mounting opening, which is directly opposite the clearance groove. The jack is located inside the mounting opening.

[0019] By adopting the above technical solution, the base supports the jack through the fixing plate, the baffle limits the displacement of the jack along the length of the base, and the installation port makes the output end of the jack face the clearance groove, which helps to improve the working stability of the jack.

[0020] Optionally, both the intermediate plate and the cover plate have rectangular holes that are directly opposite the filter plate, and the maximum diameter of the rectangular holes does not exceed the diameter of the filter plate.

[0021] By adopting the above technical solution, the rectangular holes reduce the contact area between the filter cloth and the cover plate and the intermediate plate, which is beneficial for the device to tension the filter cloth.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The base supports and fixes the middle plate and the cover plate with bolts. The middle plate and the cover plate work together to support and fix the filter plate, improving the installation stability of the filter plate. The driving component drives the extrusion plate to approach and push the PTFE graphite packing. The middle plate and the cover plate guide and limit the extrusion plate. The driving component and the filter plate work together to press and fix the PTFE graphite packing, thereby pressing the PTFE graphite packing against the filter cloth. Finally, the filter cloth is tightly attached to the filter plate, completing the filter cloth filling and improving the efficiency of the filter cloth device. 2. The base is fixed and supported by the mounting plate. The jack drives the squeezing plate to move closer to or away from the filter plate, which helps to improve the stability of the device. 3. The jack pushes the pressure plate one closer to or away from the filter plate, causing the pressure plate one to move closer to or away from the corresponding PTFE graphite packing. When the pressure plate one is close to the PTFE graphite packing, it cooperates with the aluminum plate to press and fix the PTFE graphite packing, so that the PTFE graphite packing clamps the filter cloth, making the filter cloth and the inner wall of the groove fit against the surface of the filter plate, thereby pressing and fixing the filter cloth, and thus completing the filling of the filter cloth, which helps to improve the stability and convenience of filter cloth installation.

[0027] The present application will be further described in detail below with reference to all the accompanying drawings.

[0028] This application discloses an apparatus for quickly filling filter plates and filter cloths of a rotary drum filter press. Example

[0029] Reference Figure 1 and Figure 2 A device for quickly filling filter cloth onto a rotary drum filter press filter plate 6 includes a base 1, an intermediate plate 2 mounted on the upper end of the base 1, the intermediate plate 2 being parallel to and fitted to the base 1, a cover plate 3 mounted on the upper end of the intermediate plate 2, the cover plate 3 being parallel to the intermediate plate 2, and rectangular holes 31 being provided in the middle of both the cover plate 3 and the intermediate plate 2, the two rectangular holes 31 being directly opposite each other, allowing the operator to observe the tension of the filter cloth through the rectangular holes 31. Multiple bolts 11 are threaded onto the cover plate 3 and the intermediate plate 2, the bolts 11 passing through the cover plate 3 and the intermediate plate 2 and being threadedly connected to the base 1, and nuts being threaded to both ends of the bolts 11. In the installed state, the two nuts abut against the base 1 and the cover plate 3 respectively, thereby clamping and fixing the cover plate 3 and the intermediate plate 2.

[0030] Reference Figure 1 and Figure 2 With the support of the base 1, the operator can remove the cover plate 3 from the base 1 by loosening the nut and place the filter plate 6 on the base 1 so that the filter plate 6 is aligned with the rectangular hole 31. Tighten the nut so that the intermediate plate 2 and the cover plate 3 cooperate to clamp and fix the filter plate 6, which helps to improve the installation stability of the filter plate 6.

[0031] Reference Figure 1 and Figure 2 Multiple driving components 5 are circumferentially mounted on the base 1, distributed around its perimeter. Each driving component 5 includes a mounting plate 52 and a jack 51. The mounting plate 52 includes a fixing plate 521 and two baffles 522. The fixing plate 521 is vertically mounted on the base 1, and the baffles 522 are fixedly connected to both sides of the mounting plate 52 along its length. The baffles 522 and the mounting plate 52 form an installation opening, within which the jack 51 is located and fixedly connected to the fixing plate 521. The base 1 supports and fixes the jack 51 via the fixing plate 521, while the baffles 522 limit the displacement of the jack 51 along the length of the base 1, improving the stability of the jack 51 during operation. The baffles 522 are inclined from the fixing plate 521 towards the filter plate 6, making it easier for operators to pick up or replace the jack 51, thus improving the ease of installation of the jack 51.

[0032] Reference Figure 1 and Figure 2 The output end of the jack 51 is fixedly connected to a pressing plate 4. The pressing plate 4 includes two pressing plates 41 and two pressing plates 42. The pressing plates 41 are distributed on both sides of the base 1 along the length direction, and the pressing plates 42 are distributed on both sides of the base 1 along the width direction. The pressing plates 41 and 42 are both located between the cover plate 3 and the intermediate plate 2 and are slidably connected to both the cover plate 3 and the intermediate plate 2. The pressing plates 41 and 42 are both directly opposite the groove 61. The jack 51 drives the pressing plates 41 and 42 to move closer to or away from the filter plate 6. The intermediate plate 2 and the cover plate 3 cooperate to guide and limit the pressing plates 41 and 42, which helps to improve the working stability of the pressing plates 41 and 42.

[0033] Reference Figure 1 and Figure 2When the jacks 51 on both sides of the base 1 along the length direction apply pressure, they drive the pressure plate 41 to move closer to the filter plate 6 and contact the corresponding PTFE graphite packing 62. The pressure plate 41 and the filter plate 6 cooperate to press the PTFE graphite packing 62 on both sides along the length direction of the filter plate 6, thereby making the filter cloth adhere tightly to the inner wall of the groove 61. At this time, the jacks 51 release pressure, causing the pressure plate 41 to move away from the filter plate 6. When the jacks 51 on both sides of the base 1 along the width direction apply pressure, the jacks 51 drive the pressure plate 42 to move closer to the filter plate 6. The pressure plate 42 and the filter plate 6 cooperate to press and fix the PTFE graphite packing 62, making the filter cloth adhere tightly to the inner wall of the groove 61, thereby making the surface of the filter cloth taut, thus completing the filling of the filter cloth, which is beneficial to improving the stability and convenience of filter cloth installation.

[0034] Reference Figure 2 and Figure 3 The pressure plate 42 includes a horizontal plate 421 and two vertical plates 422. The two vertical plates 422 are respectively connected to the two sides of the horizontal plate 421 and are set perpendicular to the horizontal plate 421. The end of the vertical plate 422 away from the horizontal plate 421 is provided with an inclined surface. The inclined surface slopes from the filter plate 6 towards the horizontal plate 421. When the pressure plate 42 is close to the filter plate 6, the inclined surface allows the vertical plate 422 to slide to the side of the filter plate 6. The two vertical plates 422 cooperate to allow the horizontal plate 421 to further press and fix the PTFE graphite packing 62, which is beneficial to improving the installation stability of the filter cloth.

[0035] Reference Figure 1 and Figure 2 Both the intermediate plate 2 and the cover plate 3 have circumferential clearance grooves 21 that are directly opposite the installation opening. The clearance grooves 21 are recessed from the fixed plate 521 toward the filter plate 6, providing clearance space for the output end of the jack 51, reducing the probability of the jack 51 contacting the intermediate plate 2 and the cover plate 3 and affecting the operation of the device, which is conducive to improving the working stability of the device.

[0036] The implementation principle of the device for quickly filling filter cloth of the filter plate 6 of the rotary drum filter press according to the embodiment of this application is as follows: Under the support of the base 1, the cover plate 3 and the intermediate plate 2 clamp and fix the filter plate 6. The operator activates the jacks 51 on both sides and both ends of the base 1 in sequence. The jacks 51 push the extrusion plate 4 close to and contact the PTFE graphite packing 62. The extrusion plate 4 and the filter plate 6 cooperate to press and fix the PTFE graphite packing 62, so that the filter cloth is tightly attached to the inner wall of the groove 61 and the surface of the filter plate 6. The surface of the filter cloth is in a taut state, thereby completing the filling of the filter cloth. During the filling process, it is less affected by factors such as manual replacement, personnel quality, environment and labor intensity. The filling quality of the filter cloth is high, which is conducive to improving the filling efficiency of the filter cloth.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
