Technical Field

[0001] The utility model relates to the technical field of wax emulsion processing, in particular to a filtering device used for wax emulsion processing. Background Art

[0002] Wax emulsion is widely used in papermaking and other industries. Most of the domestic wax emulsions are made of AKD, paraffin, rosin and other substances, which are used in papermaking sizing to give the paper excellent water resistance through the action of specific emulsifiers and mechanical external forces to form a relatively stable and uniform emulsion product with water.

[0003] In the prior art, the patent with publication number CN217746147U discloses a filtering device for processing wax emulsion, which is convenient for filtering a certain amount of wax emulsion stored in the main body of the device through a device body, a maintenance plate, a cover plate, a feed pipe, a bracket, a discharge pipe, a solenoid valve, an extension pipe, a limit plate, a filter plate, a connecting plate, a fixed anchor rod, a stirring bin, a stirring assembly, a mounting table, a motor, a transmission gear, a bearing, a driven gear, a stirring shaft, a filter screen, a plug rod, a jack, and a feed block. However, if the filter plate is used for a long time, particles will exist and it is easy to get clogged. There is also a method of tilting the filter plate to make large particles of impurities slide off. However, the wax emulsion has a certain viscosity and is easy to slide off with the large particles of impurities. At this time, dumping the large particles of impurities is easy to cause waste and is inconvenient to use. In view of the shortcomings of the prior art, the utility model discloses a filtering device for processing wax emulsion to solve the above problems. Summary of the invention

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0022] Example: Reference Figure 1-4The filtering device for wax emulsion processing shown in the figure comprises a device body 1, a bracket 2, a filter plate 3 and a feed pipe. It should be noted that, in this embodiment, the installation method of the device body 1, the bracket 2, the filter plate 3 and the feed pipe can refer to the technical content adopted in a filtering device for wax emulsion processing disclosed in a Chinese patent with publication number CN217746147U in the prior art, which will not be repeated here. A scraper 7 is arranged in the device body 1, and a driving mechanism for moving the scraper 7 is arranged on the device body 1. The sides of the device body 1 that are away from each other are provided with oblique holes, and the device body 1 is away from each other. Discharge plates are installed on the sides, collecting boxes 13 are installed in the front and rear of the device body 1, and a lifting and moving mechanism for moving the two collecting boxes 13 is provided on the bracket 2. Through holes are provided at the bottoms of the two collecting boxes 13, and fixed blocks 14 are installed at the bottoms of the two collecting boxes 13. Multiple sliding holes are provided on the sides of the two fixed blocks 14, and sliders 15 are slidably installed in the multiple sliding holes. Baffles 16 and U-shaped plates 18 are respectively installed at both ends of the multiple sliders 15 located on the same side that are away from each other. Two fixed plates 19 are installed on the top of the device body 1, and elastic mechanisms are provided on the sides of the two baffles 16.

[0023] By means of the above mechanism, when in use, the raw material is first poured into the device body 1 from the feed pipe, and then filtered through the filter plate 3. When the filter plate 3 is blocked, the scraper 7 is first moved back and forth by the driving mechanism. The reciprocating movement of the scraper 7 will scrape the wax emulsion blocked on the filter plate 3, and then the blocked wax emulsion falls into the two collecting boxes 13. At this time, the two collecting boxes 13 are first placed above the feed pipe by the lifting and moving mechanism, and then the two collecting boxes 13 are brought closer to each other by the lifting and moving mechanism. When the two collecting boxes 13 are moved closer to each other, the fixed block 14 will move, and the movement of the fixed block 14 will move the baffle 16 and the U-shaped plate 18 through the slider 15. When the U-shaped plate 18 contacts the fixed plate 19, the U-shaped plate 18 will no longer move with the collecting box 13. At this time, the two collecting boxes 13 continue to move, which will move the baffle 16 through the slider 15 and the U-shaped plate 18, thereby causing the wax emulsion in the collecting box 13 to fall onto the filter plate 3 through the feed pipe, thereby repeatedly filtering large particles of impurities to avoid waste caused by wax emulsion sticking to it when pouring.

[0024] like Figure 2 As shown, the lifting and moving mechanism includes two telescopic hydraulic cylinders 8 installed on the top of the bracket 2, and the output ends of the two telescopic hydraulic cylinders 8 are jointly installed with an adjusting box 9. The adjusting box 9 is provided with a moving unit that enables the two collecting boxes 13 to move relative to each other. The advantage of such a setting is that through the setting of the telescopic hydraulic cylinders 8, it is convenient to move the two collecting boxes 13 to the top of the feeding pipe.

[0025] Specifically, the output of the telescopic hydraulic cylinder 8 will move the collecting box 13, and the movement of the collecting box 13 will move the collecting box 13 through the moving unit, so that the two collecting boxes 13 move to the top of the feeding pipe.

[0026] like Figure 2-Figure 3 As shown, the moving unit includes a second motor 10 installed on the side of the adjusting box 9, a bidirectional screw rod 11 is rotatably installed relative to the inner wall of the adjusting box 9, one end of the bidirectional screw rod 11 is installed on the output shaft of the second motor 10, two threaded blocks 12 are threadedly sleeved on the bidirectional screw rod 11, and two collecting boxes 13 are respectively installed on the side walls of the two threaded blocks 12. The advantage of such an arrangement is that through the arrangement of the second motor 10, the bidirectional screw rod 11 and the threaded block 12, it is convenient to make the two collecting boxes 13 approach or move away from each other.

[0027] Specifically, the output of the second motor 10 will cause the bidirectional screw 11 to rotate, and the rotation of the bidirectional screw 11 will cause the two threaded blocks 12 to move closer to or farther away from each other. The two threaded blocks 12 moving closer to each other will cause the two collecting boxes 13 to move closer to or farther away from each other, thereby allowing the scraped wax emulsion to be filtered again to avoid residue due to incomplete filtration last time.

[0028] like Figure 2-Figure 3 As shown, the driving mechanism includes a first motor 4 installed on the side of the device body 1, and a groove is opened on the inner wall of the side of the device body 1. A reciprocating screw rod 5 is rotatably installed relative to the inner wall of the groove. One end of the reciprocating screw rod 5 is installed on the output shaft of the first motor 4, and an L-shaped plate 6 is threadedly sleeved on the reciprocating screw rod 5. The scraper 7 is installed at the bottom of the L-shaped plate 6. The advantage of this arrangement is that the scraper 7 can be easily moved back and forth through the arrangement of the first motor 4, the reciprocating screw rod 5 and the L-shaped plate 6.

[0029] Specifically, the output of the first motor 4 causes the reciprocating screw 5 to rotate, the rotation of the reciprocating screw 5 causes the L-shaped plate 6 to reciprocate, the reciprocating movement of the L-shaped plate 6 causes the scraper 7 to reciprocate, and then scrapes the filter plate 3, thereby avoiding blockage and affecting filtration. Example

[0030] like Figure 1 As shown, movable plates are installed on the sides of the device body 1 that are away from each other, electric liquid pushing rods 20 are installed at the bottom of the two movable plates, and sealing plates 21 are installed at the output ends of the two electric liquid pushing rods 20. The advantage of this arrangement is that through the arrangement of the electric liquid pushing rods 20 and the sealing plates 21, it is easy to seal the inclined holes to prevent the wax emulsion from flowing out.

[0031] Specifically, the output of the electric push rod 20 will cause the blocking plate 21 to move. When the blocking plate 21 contacts the top of the leakage plate, the blocking plate 21 blocks the inclined hole, thereby preventing the wax emulsion from flowing out. Example

[0032] like Figure 4 As shown, the elastic mechanism includes a plurality of springs 17 installed on the side of the baffle 16, and the other ends of the plurality of springs 17 are installed on the side of the fixed block 14. The advantage of such a configuration is that, through the springs 17, when the U-shaped plate 18 is not subjected to force, the baffle 16 is reset under the action of the springs 17, thereby blocking the through hole.

[0033] like Figure 4 As shown, the inner wall of the side of the collecting box 13 is inclined. The advantage of such an arrangement is that it is easy for the wax emulsion in the collecting box 13 to slide down from the through hole.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or 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 protection scope of the present invention.
