[0027] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0029] Embodiment 1, as Figure 1-Figure 5 As shown, the utility model provides a preparation device of low formaldehyde release urea-formaldehyde resin, including an operating table 1, a filter assembly 2 is arranged on the surface of the operating table 1, the filter assembly 2 includes a filter box 201 and a notch 202, the filter box 201 is arranged at the center of the surface of the operating table 1, the notch 202 is opened on the front surface of the filter box 201, and the inner walls on both sides of the notch 202 are provided with plug holes 203, a filter box 204 is arranged inside the notch 202, slots 205 are opened inside the two sides of the filter box 204, a spring 206 is arranged inside the slot 205, a push plate 207 is connected to one side of the spring 206, a dial block 208 is fixedly connected to the front surface of the push plate 207, and a plug block 209 is fixedly connected to one side of the push plate 207. A bottom plate 210 is provided at the lower end of the bottom of the filter box 201, and a slide groove 211 is provided on the surface of the bottom plate 210. A slider 214 is provided inside the slide groove 211. A collection box 212 is fixedly connected to the top of the slider 214, and a handle 213 is connected to the center of the front surface of the collection box 212. The push plate 207 forms an elastic structure with the spring 206 through the slot 205. The position and size of the plug block 209 match the position and size of the socket 203. The plug block 209 and the socket 203 form a snap-fit ​​connection. The outer surfaces of both sides of the filter box 204 fit with the inner walls of both sides of the slot 202. An oblique opening is provided on one side of the plug block 209. The collection box 212 is slidably connected with the slide groove 211 through the slider 214.

[0030] The effect achieved by the entire embodiment 1 is that when it is necessary to filter the low formaldehyde-releasing urea-formaldehyde resin, the resin is first poured into the filter box 201 so that the resin can be filtered through the filter box 204 to filter impurities, and the filtered resin will flow into the collection box 212 through the discharge port at the bottom for collection. When a lot of resin is collected in the collection box 212, the handle 213 can be grasped and pulled outward so that the collection box 212 can be slid out through the slider 214 and the slide groove 211 at the bottom, and then the resin in the collection box 212 can be taken out for the next step of preparation. When the collection box 212 needs to be installed in place, it can be directly pushed to the surface of the bottom plate 210 through the slider 214 and the slide groove 211. After long-term use, the surface of the filter box 204 will absorb more impurities. When the filter box 204 needs to be pulled out for cleaning, the two sets of dial blocks 208 can be pushed inward at the same time so that the dial blocks 208 can drive the push plate 207 to squeeze the spring 206. At this time, the plug block 209 will also be pulled out from the socket 203, and the filter box 204 can be slid out from the slot 202, and the filter box 204 can be cleaned. After the filter box 204 is cleaned, when it needs to be installed, the filter box 204 can be directly pushed into the slot 202. When the oblique mouth of the plug block 209 contacts the inner wall of the slot 202, the filter box 204 is pushed further, so that the plug block 209 is squeezed by the inner wall of the slot 202 and is pushed through the push plate 207. The spring 206 is squeezed and the insert block 209 itself is also contracted toward the slot 205. After the filter box 204 is completely inserted into the slot 202, the spring 206 will push the push plate 207 through its own elastic force to drive the insert block 209 to be inserted into the socket 203 to fix the filter box 201, thereby avoiding the problem that the existing filtering device does not fix the filter box 204, which greatly reduces the filtering effect and may even make the filtering effect completely ineffective, thereby improving the stability of filtering resin.

[0031] Embodiment 2, as Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, a stirring assembly 3 is arranged directly above the filter box 201, and the stirring assembly 3 includes an electric push rod 301 and a support plate 302. Four groups of electric push rods 301 are respectively arranged at the four corners of the surface of the operating table 1, and the support plate 302 is connected to the output ends of the four groups of electric push rods 301. The center position of the surface of the support plate 302 is connected to a motor 303, and the output end of the motor 303 is connected to a stirring rod 304. The outer surfaces of both sides of the stirring rod 304 are connected to connecting blocks 305. The outer surface of the connecting block 305 is attached with a scraper 306, and a threaded rod 307 is inserted inside the scraper 306. A threaded hole 308 is opened on the outer surface of the connecting block 305 on one side close to the scraper 306. The threaded rod 307 penetrates the scraper 306 and forms a threaded connection with the threaded hole 308. The output end of the motor 303 penetrates the support plate 302 and forms a fixed connection with the stirring rod 304. The motor 303 is electrically connected to an external power supply through a control switch, and the four groups of electric push rods 301 are the same group of control switches.

[0032] The effect achieved by the entire embodiment 2 is that when the resin is poured into the filter box 201 for filtering, the stirring rod 304 can be driven to rotate by turning on the motor 303, and then the retraction function of the electric push rod 301 is turned on, so that the four groups of electric push rods 301 drive the support plate 302 to move downward through the output end, and the stirring rod 304 is inserted into the filter box 201 to stir the resin, thereby increasing the liquid speed near the inner wall of the filter box 201, and during the stirring process, the scraper 306 will remove the dirt adhering to the surface of the filter medium, reducing the resistance of the surface of the filter box 204, and when the resin is filtered, the motor 303 can be turned off to stop. Stop the rotation of the stirring rod 304, then turn on the electric push rod 301 to push the support plate 302 upward, and pull the stirring rod 304 out of the filter box 201, thereby completing the stirring of the resin. When the scraper 306 is worn out after long-term use and needs to be replaced, the threaded rod 307 can be rotated in the opposite direction so that the threaded rod 307 can be taken out from the threaded hole 308, and the worn scraper 306 can be removed and replaced with a new scraper 306. In this way, the filtration efficiency of the resin can be improved by the stirring rod 304 and the scraper 306, the filling and clogging of local areas can be reduced, the pores can be wider, and the filtration speed can be further improved.

[0033] Working principle: When filtering the resin, the filter box 204 can be inserted into the slot 202 to filter the impurities in the resin, and the spring 206 will drive the plug 209 to be inserted into the socket 203 through the push plate 207 to fix the filter box 204, thereby filtering the resin, and then the filtered resin can be collected through the collection box 212, thereby avoiding the problem that the existing filtering device does not fix the filter box 204, which will greatly reduce the filtering effect, and may even make the filtering effect completely ineffective. While filtering the resin, the motor 303 can drive the stirring rod 304 to stir the resin in the filter box 201, increase the liquid speed near the inner wall of the filter box 201, and remove the dirt adhering to the surface of the filter medium through the scraper 306, reduce the resistance on the surface of the filter box 204, and thus improve the filtering efficiency.

Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes and apply them to other fields.
