DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0028] As Figures 1 to 7 shown, the present application provides a belt filter device for producing chlorinated polyethylene, which comprises a bottom plate 1, the upper surface of the bottom plate 1 is fixedly connected with a collecting tank 2, the inside of the collecting tank 2 is fixedly installed with a cleaning box 3, the upper part of the cleaning box 3 is fixedly connected with a cleaning assembly 4, the upper surface of the rear part of the bottom plate 1 is fixedly connected with a water supply system 5, the front surface of the water supply system 5 is fixedly connected with the rear part of the cleaning assembly 4, the left and right outer sides of the cleaning box 3 are both fixedly connected with a first fixed rotating shaft 6, the inside of the cleaning box 3 is fixedly connected with a guide plate 7, the upper surface of the bottom plate 1 is provided with a filter cloth transmission structure, the surface of the filter cloth transmission structure is drivingly connected with a filter cloth 8, and the filter cloth 8 is movably connected with the inside of the cleaning box 3.

[0029] In the chlorinated polyethylene production process, the mixed solution is poured onto the upper surface of the left part of the filter cloth 8. As the transmission rubber net 17 and the filter cloth 8 are transmitted, the chlorinated polyethylene solution that can pass through the filter cloth 8 falls into the inside of the collection tank 2, and the impurities that cannot pass through the filter cloth 8 are discharged from one end of the second rotating shaft 26. However, since the filter cloth 8 belongs to the transmission belt, it will be transmitted from below the transmission rubber net 17 after being filtered and then transmitted to the upper surface of the transmission rubber net 17. Therefore, when passing through the inside of the cleaning box 3, the water supply system 5 is started. Due to the water supply function of the water supply system 5, the filter cloth 8 passing through the inside of the cleaning box 3 is cleaned and then sent to the upper surface of the flow guide plate 7. However, the cleaning assembly 4 can send the water required for cleaning into the inside of the cleaning box 3. However, the cleaned sewage is discharged into the guide groove 32 from the upper surface of the flow guide plate 7 due to the action of gravity. The first fixed rotating shaft 6 plays a protective role for the filter cloth 8 entering the inside of the cleaning box 3.

[0030] The upper surface of the bottom plate 1 is fixedly connected with the air cylinder 9. The output shaft of the air cylinder 9 is fixedly connected with the supporting plate 10. The upper surface of the supporting plate 10 is fixedly connected with the fixed block 11. The inside of the fixed block 11 is rotatably connected with the pressing shaft 12. The front upper surface of the supporting plate 10 is fixedly connected with the first motor 13. The output shaft of the first motor 13 is fixedly connected with the front part of the pressing shaft 12.

[0031] Before the impurities are discharged from the upper part of the second rotating shaft 26, the air cylinder 9 is started. Due to the rising and falling of the output shaft of the air cylinder 9, the distance between the pressing shaft 12 and the second rotating shaft 26 is adjusted. The fixed block 11 provides support force for the pressing shaft 12. Then the first motor 13 is started. Due to the rotation of the output shaft of the first motor 13, the pressing shaft 12 is driven to rotate. Since the rotation directions of the second rotating shaft 26 and the first motor 13 are opposite, the impurities on the upper surface of the filter cloth 8 can be extruded into blocks and discharged from the right end of the second rotating shaft 26.

[0032] The inside of the collection tank 2 is fixedly connected with the support 14. The upper surface of the support 14 is fixedly connected with the second motor 15. The output shaft of the second motor 15 is fixedly connected with the first rotating shaft 16. The front and rear ends of the first rotating shaft 16 are rotatably connected with the inside of the support 14. The surface of the first rotating shaft 16 is transmissionally connected with the transmission rubber net 17.

[0033] The support 14 provides support for the first rotating shaft 16. The rotation of the output shaft of the second motor 15 drives the transmission of the transmission rubber net 17, thereby providing certain support force for the materials on the upper surface of the filter cloth 8. Since the transmission speed of the transmission rubber net 17 and the filter cloth 8 is equal, the filter cloth 8 and the transmission rubber net 17 will not be damaged due to friction.

[0034] The upper surface of the support 14 is fixedly connected with the connecting frame 18. The inside of the connecting frame 18 is fixedly connected with the cross rod 19. The lower surface of the cross rod 19 is fixedly connected with the flow divider 20.

[0035] The crossbar 19 is given a mounting point by the connecting frame 18, but the flow diverter 20 can divert the sundries on the upper surface of the filter cloth 8 multiple times, so that the chlorinated polyethylene solution inside the filter cloth 8 can pass through the filter cloth 8 and fall into the inside of the collection tank 2.

[0036] The upper surface of the bottom plate 1 is fixedly connected with a first support frame 21, and the inner surface of the first support frame 21 is fixedly connected with a scraper 22.

[0037] The first support frame 21 provides support for the scraper 22, but the scraper 22 scrapes off the sundries that are pressed on the surface of the filter cloth 8.

[0038] The upper surface of the bottom plate 1 is fixedly connected with a second support frame 23, and the upper surface of the second support frame 23 is fixedly connected with a terminal flow guide plate 24.

[0039] The second support frame 23 provides support for the terminal flow guide plate 24, but the design of the terminal flow guide plate 24 prevents solid sundries from detaching from the upper surface of the filter cloth 8 when they are detached from the front and rear sides of the transmission rubber net 17.

[0040] The filter cloth transmission structure includes a third motor 25 fixedly connected to the upper surface of the right part of the bottom plate 1, and the output shaft of the third motor 25 is fixedly connected with a second rotating shaft 26, the surface of the second rotating shaft 26 is attached to the inner surface of the filter cloth 8, and the upper surface of the left part of the bottom plate 1 is fixedly connected with a fourth motor 27, and the output shaft of the fourth motor 27 is fixedly connected with a third rotating shaft 28, and the surface of the third rotating shaft 28 is attached to the inner surface of the filter cloth 8.

[0041] The third motor 25 is started to drive the rotation of the second rotating shaft 26, and the fourth motor 27 is started to drive the rotation of the third rotating shaft 28, but the rotation of the second rotating shaft 26 and the third rotating shaft 28 drives the transmission of the filter cloth 8.

[0042] The filter cloth transmission structure further includes a second fixed rotating shaft 29 fixedly connected to the side surface of the support 14, and the left side surface of the support 14 is fixedly connected with a fixed frame 30, and the electric rotating shaft 31 is rotatably connected inside the fixed frame 30.

[0043] The second fixed rotating shaft 29 assists the filter cloth 8 in forming the required shape, so that the sundries can be filtered by gravity in the first round, because the sundries fall from the upper surface of the left part of the transmission rubber net 17 to the upper surface of the right part of the transmission rubber net 17, thereby filtering the chlorinated polyethylene solution more effectively, but the rotation of the electric rotating shaft 31 facilitates the normal transmission of the filter cloth 8.

[0044] The rear surface of the collecting groove 2 is fixedly connected with a flow guide groove 32, the left end of the flow guide groove 32 is in a closed state, and the right end of the flow guide groove 32 is in an open state.

[0045] Through the design of the flow guide groove 32, the sewage used for cleaning inside the cleaning box 3 can be discharged from the second support frame 23, so that the right end of the device is collected.

[0046] The filter cloth 8 is attached to the upper surface of the transmission rubber net 17, and the left wall of the collecting groove 2 is provided with a discharge port 33.

[0047] The transmission rubber net 17 provides a material supporting force to the upper surface of the filter cloth 8, and the design of the discharge port 33 can collect the chlorinated polyethylene solution inside the collecting groove 2.

[0048] The working principle and use process of the utility model are as follows:

[0049] In the chlorinated polyethylene production process, the mixed solution is poured onto the left upper surface of the filter cloth 8, and along with the transmission of the transmission rubber net 17 and the filter cloth 8, the chlorinated polyethylene solution can fall into the inside of the collecting groove 2 through the filter cloth 8, and the impurities that cannot pass through the filter cloth 8 are discharged from one end of the second shaft 26, and because the filter cloth 8 is a transmission belt, it will be transmitted from below the transmission rubber net 17 after being filtered, and then transmitted to the upper surface of the transmission rubber net 17, so when passing through the inside of the cleaning box 3, the water supply system 5 is started, and because of the water supply function of the water supply system 5, the filter cloth 8 passing through the inside of the cleaning box 3 is cleaned and then sent to the upper surface of the flow guide plate 7, and the cleaning assembly 4 can send the water required for cleaning into the inside of the cleaning box 3, and the sewage after cleaning is discharged into the flow guide groove 32 from the upper surface of the flow guide plate 7 due to the action of gravity, and the first fixed shaft 6 protects the filter cloth 8 from entering the inside of the cleaning box 3.

[0050] Before the impurities are discharged from the upper part of the second shaft 26, the cylinder 9 is started, and because the output shaft of the cylinder 9 rises and falls, the distance between the pressure shaft 12 and the second shaft 26 is adjusted, the fixed block 11 provides supporting force to the pressure shaft 12, then the first motor 13 is started, and because the output shaft of the first motor 13 rotates, the pressure shaft 12 is driven to rotate, and because the rotation directions of the second shaft 26 and the first motor 13 are opposite, the impurities on the upper surface of the filter cloth 8 can be extruded into blocks and discharged from the right end of the second shaft 26.

[0051] The support 14 provides supporting action to the first shaft 16, and the transmission of the transmission rubber net 17 is driven by the rotation of the output shaft of the second motor 15, so as to provide a certain supporting force for the material on the upper surface of the filter cloth 8, and because the transmission speeds of the transmission rubber net 17 and the filter cloth 8 are equal, the filter cloth 8 and the transmission rubber net 17 will not be damaged due to friction.

[0052] The cross bar 19 is given a mounting point by the connecting frame 18, however the shunt 20 can shunt the impurities on the upper surface of the filter cloth 8 multiple times, so that the chlorinated polyethylene solution inside the filter cloth 8 can pass through the filter cloth 8 and fall into the inside of the collection tank 2.

[0053] The scraper 22 is given a supporting force by the first supporting frame 21, however the scraper 22 scrapes off the impurities that are pressed on the surface of the filter cloth 8.

[0054] The end deflector 24 is given a supporting force by the second supporting frame 23, however the design of the end deflector 24 prevents the solid impurities from separating from the upper surface of the filter cloth 8 when they are separated from the front and back sides of the transmission rubber net 17.

[0055] The second rotating shaft 26 is driven to rotate by the starting of the third motor 25, and the third rotating shaft 28 is driven to rotate by the starting of the fourth motor 27, however the rotation of the second rotating shaft 26 and the third rotating shaft 28 drives the transmission of the filter cloth 8.

[0056] The second fixed rotating shaft 29 helps the filter cloth 8 to form a required shape, so that the impurities can be filtered by gravity in the first round, because the impurities fall from the upper surface of the left transmission rubber net 17 to the upper surface of the right transmission rubber net 17, so as to filter the chlorinated polyethylene solution more effectively, however the rotation of the electric rotating shaft 31 helps the filter cloth 8 to be normally transmitted.

[0057] The design of the deflector groove 32 can discharge the sewage used for cleaning in the cleaning tank 3 from the second supporting frame 23, so as to be collected at the right end of the device.

[0058] The transmission rubber net 17 gives the material on the upper surface of the filter cloth 8 a supporting force, however the design of the discharge port 33 can collect the chlorinated polyethylene solution in the collection tank 2.

[0059] The above is only a preferred embodiment of the present application, and is not used to limit the present application, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
