[0003] As disclosed in CN213823728U, a filtration device for formaldehyde removal agent production includes a housing comprising an upper housing and a lower housing, separated by a hopper. The lower housing has a drain pipe and a slag discharge pipe at its bottom. A first pipe is installed at the bottom of the hopper, a flexible hose is installed at the bottom of the first pipe, and a second pipe is installed at the bottom of the flexible hose. One side of the second pipe is fixed to the output end of an electric telescopic rod, which is installed in the lower housing. The other side of the second pipe is installed to an auxiliary telescopic rod, which is also installed in the lower housing. This filtration device uses a rotatable filter tank to filter impurities from liquid raw materials, making fuller use of the filter tank and significantly extending the filtration time per pass. Furthermore, the filter tank can be easily cleaned after filtration, allowing for convenient removal of internal filter residue and quick reuse.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-7 The present invention provides the following technical solution.

[0034] Example 1: To address the problem in existing technologies where it is inconvenient to adjust the feeding speed of the filtered liquid, this example provides a formaldehyde production filtration device that facilitates the cleaning of filter residue. The device comprises a housing 1, a fixed support 2, a feeding port 3, a filter cylinder 4, a connecting mechanism 5, a connecting rod 11, and a connecting bolt 12. The housing 1 is fixed to the upper end of the fixed support 2, and the feeding port 3 is located at the upper end of the housing 1. The filter cylinder 4 is rotatably mounted in the middle of the housing 1, and its upper end has an opening. The lower end of the feeding port 3 is directly opposite the opening at the upper end of the filter cylinder 4. The connecting mechanism 5 is located at the lower end of the housing 1 and is used for feeding and adjusting the feeding speed. The enclosure includes a feeding cylinder 6 fixedly connected to the bottom of the housing 1, fixed blocks 7 fixedly connected to the left and right ends of the feeding cylinder 6, a movable plate baffle 8 sleeved on the outer surface of the feeding cylinder 6, and a connecting groove 9 opened at the rear end of the bottom of the movable plate baffle 8. The movable plate baffle 8 and the fixed blocks 7 form a sliding structure, and a sealing gasket is fitted between the movable plate baffle 8 and the feeding cylinder 6. A connecting post 10 is fixedly connected to the front end of the movable plate baffle 8, and the upper end of the front side of the connecting post 10 forms a sliding structure with the connecting rod 11. The connecting rod 11 is fixedly connected to the front side of the lower end of the housing 1, and the connecting rod 11 and the connecting post 10 are limited by a connecting bolt 12. The connecting bolt 12 and the connecting rod 11, as well as the connecting bolt 12 and the connecting post 10, are all threaded connections. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the formaldehyde removal agent raw material solution is added to the filter cylinder 4 inside the box 1 through the feeding port 3. The formaldehyde removal agent raw material solution is filtered by the filter screen set on the outer surface of the filter cylinder 4. The filtered solution is discharged outward by the adjusting column 13. At the same time, during the feeding process, the connecting column 10 is pulled, and the connecting column 10 slides between the connecting column 10 and the connecting rod 11. The connecting column 10 drives the movable plate baffle 8 to slide between the fixed block 7. In this way, the feeding rate of the solution is adjusted by adjusting the overlapping area of ​​the connecting groove 9 and the lower opening of the feeding cylinder 6.

[0035] Example 2: Existing formaldehyde production filtration devices, which are easy to clean, are inconvenient for discharging and cleaning the filtered residue. Therefore, by setting an adjusting column 13, a limiting rod 14, a support rod 15, and a connecting cap 16, the adjusting column 13 is fixedly connected to the right end of the filter cylinder 4, and the adjusting column 13 and the housing 1 form a rotating structure. The adjusting column 13 drives the filter cylinder 4 to form a flipping structure in the housing 1, and the angle range of the filter cylinder 4 flipping in the housing 1 is 0-180º. The right end of the adjusting column 13 is engaged with the limiting rod 14, and the front and rear ends of the limiting rod 14 are both inserted with support rods 15. The support rods 15 are fixedly connected to the front and rear sides of the right end of the housing 1, and the outer surface of the support rods 15 is threaded with connecting caps 16 for limiting. The connecting caps 16 are respectively fitted and disposed on the front and rear sides of the limiting rod 14. Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, by rotating the connecting cap 16 threaded onto the outer surface of the support rod 15, the connecting cap 16 disengages from the support rod 15, thereby releasing the restriction between the limiting rod 14 and the support rod 15. Then, by pulling the limiting rod 14 to the right, the limiting rod 14 slides between itself and the support rod 15, causing the limiting rod 14 to disengage from the adjusting column 13, thereby releasing the restriction between the adjusting column 13 and the housing 1. Then, by rotating the adjusting column 13, the adjusting column 13 rotates with the housing 1, causing the filter cylinder 4 to rotate 180° within the housing 1, as shown in the diagram. Figure 7 As shown in the diagram, the filter residue filtered out inside the filter cylinder 4 is poured out through the opening on the filter cylinder 4, and the area of ​​the opening at the lower end of the adjusting column 13 overlapping with the connecting groove 9 is adjusted to the maximum, so that the filter residue can be discharged downward through the adjusting column 13, thus facilitating the cleaning of the filter residue.

[0036] Example 3: Existing formaldehyde production filtration devices that facilitate filter residue removal are inconvenient for rinsing and thoroughly cleaning the filter cartridge 4, leaving residues. Therefore, a cleaning pipe 17 and nozzles 18 are installed. The cleaning pipe 17 is fixedly installed at an equal angle on the upper end of the housing 1 and on the inner walls of the front and rear sides of the upper end. The cleaning pipe 17 is connected to an external water source via a water pump. Nozzles 18 are installed at equal intervals on the outer surface of the cleaning pipe 17, with the nozzles 18 facing the filter cartridge 4. Figure 2 , Figure 2 and Figure 7 As shown, water is pumped into the cleaning pipe 17 by an external water pump and sprayed out by the nozzle 18, which facilitates the rinsing of the filter screen on the filter cylinder 4, prevents residue, and allows for thorough cleaning of the filter residue.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
