[0015] Compared with the prior art, the present invention has the following beneficial effects: the disc filter with assembled filter disc structure, (1) The present invention can effectively solve the problem of the existing disc filter assembly method of requiring workers to climb to the top of the disc filter and then manually assemble the filter discs. Working at a height for a long time poses a great safety hazard, and the manual assembly efficiency is low. The motor drives the feed roller to rotate. When the feed roller rotates, it pushes the filter disc to be assembled inside the limit groove to move, so that the filter disc is assembled and connected to the long axis through the plug-in assembly on the side. At the same time, after the current filter disc is assembled, the pressure on the reset spring group is synchronously reduced.

The screw is driven by the belt transmission mechanism to rotate along the long axis, so that the automatic assembly mechanism moves horizontally along the screw. When the automatic assembly mechanism moves to the assembly position of the next filter disc, the electric push rod in the chuck assembly automatically contracts and separates the screw from the slot on the rotating shaft. As a result, when the long axis is assisted in rotating for assembly, the screw and the automatic assembly mechanism threaded above it are fixed in position, thereby ensuring the normal progress of the assembly operation, thereby realizing the assembly requirements of the filter discs at different positions on the long axis.

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1-10 The present invention provides a technical solution: a disc filter with a filter disc assembly structure, comprising an automatic assembly mechanism 1 and a long shaft 8, the automatic assembly mechanism 1 comprising a machine base 101, and a reset spring assembly 102 is fixedly connected to the inner side wall of one side of the machine base 101, while the other end of the reset spring assembly 102 is connected to a top plate 103, a feed roller 106 is provided on one side of the top plate 103, and the feed roller 106 is rotatably connected to the mounting cavity of the inner side wall of the other side of the machine base 101, the filter disc 3 to be assembled is stacked between the top plate 103 and the feed roller 106, and the filter disc 3 is fixedly connected to a plug assembly 10. The top of the feed roller 106 is fixedly connected to the motor 105, and the outer wall of the feed roller 106 is connected to the protective belt 107. A limiting groove 108 is provided on the inner bottom of the machine base 101, and a driven adjustment mechanism 2 is provided below the machine base 101. At the same time, the driven adjustment mechanism 2 is used to adjust the position of the machine base 101. When working, the filter disc 3 is first neatly stacked between the feed roller 106 and the return spring group 102. At this time, the return spring group 102 is in the maximum extrusion and contraction state. Figure 7 As shown, the power starter is then connected, and the motor 105 drives the feed roller 106 to rotate. When the feed roller 106 rotates, the friction between the protective belt 107 and the filter disc 3 is used to pull out the filter disc 3 to be assembled on the inside of the limit groove 108, and the pulled out filter disc 3 is assembled and connected to the long shaft 8 through the side plug-in assembly, thereby completing the assembly of a single filter disc 3. After the assembly of the current filter disc 3 is completed, the squeezing force of the return spring group 102 is synchronously reduced due to the reduction of the filter disc 3, thereby pushing the top plate 103 and the remaining filter discs 3 stacked inside it to move toward the feed roller 106, so that a filter disc 3 close to the feed roller 106 is filled into the limit groove 108, and then the motor 105 drives the feed roller 106 to rotate and repeat the above operation to continuously pull out the filter disc 3, and then the filter disc 3 can be continuously and automatically assembled by the feed roller 106.

[0019] The limiting groove 108 is internally slidably connected to a pressure plate 109, and the telescopic end of the electric telescopic rod 1010 is fixedly connected to the rear side wall of the pressure plate 109. At the same time, the fixed end of the electric telescopic rod 1010 is fixedly connected to a hanging plate, and the hanging plate is fixedly connected to the rear side wall of the guide plate 104. The guide plate 104 is fixedly connected to the inner wall of the machine base 101. In order to prevent the plug-in component from being loosely connected, after the filter disc 3 is assembled, the electric telescopic rod 1010 pushes the pressure plate 109 to move back and forth along the limiting groove 108 to reciprocate and impact the side wall of the filter disc 3, thereby improving the stability of the connection of the plug-in component.

[0020] The long shaft 8 is arranged inside the filter seat 13, and the side of the filter seat 13 is fixedly connected to the frame 12. A material guide port for unloading is opened in the left frame 12. A filter drive unit 10 is installed on the outer wall of the frame 12. A pneumatic connection end 9 is provided on one side of the long shaft 8, and the pneumatic connection end 9 is respectively connected to a vacuum generating device 11 and a blower. The long shaft 8 is driven to rotate by the filter drive unit 10, and a plurality of groups of filter discs 3 are distributed in a circular array on the long shaft 8. The front and rear outer walls of the filter discs 3 are fixed with filter cloths 4. When working, the filter drive unit 10 drives the long shaft 8 to rotate. The shaft 8 drives the multiple groups of filter discs 3 to rotate counterclockwise. Driven by the vacuum generating device 11, the filter discs 3 continuously suck the pollutants inside the filter seat 13, so that the pollutants are adsorbed on the filter cloth 4 on its surface to form a filter cake. When the long shaft 8 drives the filter cake to rotate away from the filtrate inside the filter seat 13, the moisture of the filter cake is further adsorbed. At this time, the long shaft 8 continues to drive the filter cake to rotate so that it is continuously dehydrated. When the long shaft 8 rotates to 270 degrees, the blower pumps exhaust air into the interior of the filter disc 3, thereby blowing the filter cake off the filter cloth 4 and causing it to fall into the interior of the guide port. Figure 9 The filtrate and gas extracted by the vacuum generating device 11 during the suction process enter the externally connected drainage tank, that is, the gas is discharged from the top of the drainage tank, and the filtrate is discharged through the drainage pipe at the bottom.

[0021] The plug-in assembly includes a card column 6, which is fixedly connected to one side wall of the filter disc 3, and two groups of card columns 6 are symmetrically arranged. A first connecting head 5 is arranged on the inner side of the two groups of card columns 6. The first connecting head 5 is engaged and connected to the second connecting head 7, and the second connecting heads 7 are distributed in a ring array on the long axis 8. At the same time, the second connecting head 7 is an inflatable joint. The existing filter disc 3 is installed by bolts, and the filter disc 3 is usually provided with multiple groups, and the number of each group is large, which makes the installation of the bolts more troublesome, that is, the filter disc 3 is engaged with the second connecting head 7 through the first connecting head 5, and then the second connecting head 7 is inflated to expand it, so as to tighten the connection relationship between the first connecting head 5 and the second connecting head 7, and the operation is more convenient. At the same time, the card column 6 can establish a new connection relationship between the filter disc 3 and the long axis 8, thereby further improving the stability of the connection.

[0022] Micropores are provided on the pressure plate 109, and the pressure plate 109 is connected to the exhaust end of the vacuum generating device 11 through a pipe. When the filter disc 3 needs to be disassembled, the staff can open the valve on the pipe connecting the pressure plate 109 and the vacuum generating device 11, that is, when performing the disassembly work, first release the gas inside the second connecting head 7, and then control the electric telescopic rod 1010 to push the pressure plate 109 inward to contact a group of filter discs 3 to be disassembled, and adsorb the filter disc 3 through the micropores. Then, by controlling the electric telescopic rod 1010 to pull the pressure plate 109 to reset, the filter disc 3 is pulled off the long axis 8, and the disassembly process is simple.

[0023] A stirring assembly is provided below the long axis 8, and the stirring assembly rotates in the same direction as the long axis 8. At the same time, the stirring assembly is driven to rotate by the filter drive unit 10. During the filtration process, pollutants are easily deposited on the bottom and side walls of the filter seat 13, thereby affecting the sewage storage capacity of the filter seat 13 and the filter cake formation efficiency. When the long axis 8 drives the filter disc 3 to adsorb and filter the sewage, the stirring assembly rotates to stir the sewage mixture, thereby promoting the flow of sewage and pollutants inside the filter seat 13, so that it is in full contact with the filter disc 3, thereby improving the filter cake formation efficiency.

[0024] The driven adjustment mechanism 2 includes a screw rod 201, and the screw rod 201 is connected to the bottom of the machine base 101. At the same time, one end of the screw rod 201 is fixedly connected to the chuck assembly 202. The chuck assembly 202 is connected to the long shaft 8 through a belt transmission structure 203. Most existing assembly structures require external driving equipment for independent driving, which has high cost. Under the transmission action of the belt transmission structure 203, the chuck assembly 202 will drive the screw rod 201 to rotate, so that the automatic assembly mechanism 1 threadedly connected to the screw rod 201 can move in the frame 12, thereby facilitating the automatic assembly mechanism 1 to install the filter disc 3 at different positions on the long shaft 8, and the entire moving operation does not require additional driving equipment to drive.

[0025] The chuck assembly 202 is a quick-release structure, and the chuck assembly 202 is rotatably connected to the inside of the frame 12. The chuck assembly 202 includes a disc, and a slot is provided on the disc. An electric push rod 204 is relatively provided on one side of the slot, and the end of the electric push rod 204 away from the slot is fixedly connected to the rotating shaft, and the rotating shaft is fixedly connected to the belt transmission structure 203. When the long shaft 8 needs to be rotated to adjust the position of the filter disc 3, and the automatic assembly mechanism 1 does not need to move at this time, the staff can control the electric push rod 204 to retract away from the slot, thereby disconnecting the connection between the rotating shaft and the screw rod 201, that is, the rotating shaft continues to rotate under the drive of the belt transmission structure 203, and the screw rod 201 stops rotating due to lack of a driving source, thereby meeting different usage requirements.

[0026] The end of the filter disc 3 away from the first connector 5 is fixedly connected to the fastening assembly 14, the fastening assembly 14 includes a fastening seat 1401, and the fastening seat 1401 is provided with a cavity 1403, and the cavity 1403 is fixedly connected to a mounting block 1404, one side of the mounting block 1404 is fixedly connected to a telescopic spring group 1405, and the end of the telescopic spring group 1405 away from the mounting block 1404 is fixedly connected to a guide rod 1406, the guide rod 1406 is slidably connected to the inside of the cavity 1403, and the end of the guide rod 1406 away from the telescopic spring group 1405 is fixedly connected to an insert block 1407, the fastening seat 1401 is provided with a fastening groove 1402, and the fastening groove 1402 and the insert block 14 07 is adapted. After the existing filter disc 3 is assembled, a group of arc plates are usually installed on its outer edge side wall for connecting two closely adjacent groups of filter discs 3. The operation is relatively troublesome. During the process of assembling the filter disc 3, that is, when the electric telescopic rod 1010 pushes the pressure plate 109 to move back and forth to push the filter disc 3, the plug block 1407 will continue to squeeze the internal telescopic spring group 1405 until the first connecting head 5 is engaged with the second connecting head 7. At this time, the plug block 1407 corresponds to the fastening groove 1402 on the assembled filter disc 3, and the plug block 1407 will be engaged in the fastening groove 1402 under the push of the telescopic spring group 1405, thereby achieving the fixation of the two adjacent groups of filter discs 3.

[0027] The top of the mounting block 1404 is fixedly connected to a lever 1408, and the lever 1408 is arranged on the outside of the fastening seat 1401. A limiting member 1409 is provided on one side of the lever 1408, and the limiting member 1409 is connected to the mounting block 1404 and the fastening seat 1401. When the filter disc 3 needs to be removed, the staff can remove the limiting member 1409 used to fix the fastening seat 1401, and then move the lever 1408 to move the position of the mounting block 1404, so that the insertion block 1407 is separated from the fastening groove 1402, so that the filter disc 3 can be adsorbed and removed.

[0028] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
