Description

Technical Field

[0001] The utility model relates to a high-efficiency reactor for producing urea resin, belonging to the technical field of reactors. Background Art

[0002] Urea resin is a synthetic resin primarily produced through the polymerization of chemical raw materials such as urea and formaldehyde. It exhibits excellent wear and corrosion resistance, as well as mechanical strength, and is often used as a base material for adhesives and coatings. Urea resin is widely used in wood processing and composite material manufacturing, enhancing the hardness and water resistance of materials while also exhibiting excellent weather resistance and chemical stability. It is a key component in industrial products and building materials. Urea resin processing requires the use of a reactor to mix the raw materials.

[0003] A Chinese patent publication (publication number: CN 219002914 U) discloses a urea-formaldehyde resin reactor, comprising: a stirring shaft, a scraper, and a reactor body. The cylindrical wall of the reactor body is provided with a plurality of through holes and a plurality of grooves, wherein the grooves are used to place sensors. The side surface of the scraper contacts the inner wall of the reactor body, and the scraper is fixedly mounted on the stirring shaft. The stirring shaft drives the scraper to rotate coaxially, so that the scraper scrapes the inner wall of the reactor body. The novel urea-formaldehyde resin reactor designed by the utility model adopts a stirring shaft to drive a stirring head to stir the reactants, thereby making the mixing more complete and accelerating the reaction efficiency. At the same time, the stirring shaft also drives the connecting rod to rotate, thereby driving the scraper to clean the urea-formaldehyde resin adhesive adhered to the surface of the plurality of sensors and the conduit port, thereby avoiding clogging of the conduit and temperature sensor, and reducing the impact on the conveying efficiency and detection accuracy.

[0004] The stirring equipment in the above-mentioned device is relatively simple and can only stir the material in a single direction. The stirring efficiency depends not only on the stirring speed, but also on the stirring method and direction. Stirring in a single direction is difficult to achieve all-round mixing, which may lead to uneven mixing, affect the performance of the urea resin, and be inconvenient for operators to use.

[0005] Therefore, a high-efficiency reactor for producing urea resin is proposed. Utility Model Content

The stirring mechanism 2 includes a first drive motor 201, a second drive motor 203 and a stirring rod 207. The first drive motor 201 is fixedly installed at the bottom of the reactor body 1, and the output end of the first drive motor 201 is fixedly connected to the stirring pipe 202. The second drive motor 203 is fixedly installed on the reactor body. 1, the output end of the second drive motor 203 is fixedly connected to the connecting rod 204, and the six stirring rods 207 are movably connected to the left and right sides of the stirring tube 202 through bearings. The surfaces of the six stirring rods 207 are fixedly installed with stirring blades 208, and the surfaces of the connecting rods 204 are fixedly installed with driving bevel gears 205. The inner sides of the six stirring rods 207 are fixedly installed with driven bevel gears 206. The surfaces of the six driven bevel gears 206 are meshed with the surfaces of the three driving bevel gears 205. The six stirring rods 207 and the stirring blades 208 are all the same size, and the six stirring rods 207 and the stirring blades 208 are symmetrical to each other.

[0030] By setting up the stirring mechanism 2, the output of the first drive motor 201 causes the stirring tube 202 to rotate, and drives the stirring blade 208 and the stirring rod 207 to rotate in the circumferential direction. Then the output of the second drive motor 203 causes the stirring rod 207 and the stirring blade 208 to rotate in the horizontal direction. Through the multi-directional rotation of the stirring blade 208 and the stirring rod 207, the stirring blade 208 can fully stir the urea resin in the inner cavity of the reactor body 1, thereby improving the uniformity of the all-round mixing of the urea resin raw materials and the efficiency of the stirring of the urea resin, ensuring the stability of the urea resin synthesis, and facilitating the use of the operator.

[0031] Example 2

[0032] like Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, in one embodiment, a cross plate 209 is fixedly installed on the surface of the stirring tube 202, and the bottom of the cross plate 209 is in contact with the bottom of the reactor body 1. Scrapers 210 are arranged on all sides of the top of the cross plate 209, and the outer sides of the four scrapers 210 are all in contact with the inner wall of the reactor body 1. The inner sides of the four scrapers 210 are provided with card slots 211, and clamping rods 212 are fixedly installed on all sides of the top of the cross plate 209.

A bottom plate 8 is fixedly installed on the bottom of the support frame 7, and the top of the bottom plate 8 is threadedly connected with anchor bolts 9.

[0033] By providing the cross plate 209, the material at the bottom of the reactor body 1 can be stirred to avoid the sedimentation of the material, which affects the uniformity of the stirring of the urea resin. By providing the scraper 210, the material stuck to the inner wall of the reactor body 1 can be scraped off, which facilitates the discharge of the stirred urea resin. By providing the card slot 211 and the card rod 212, the scraper 210 can be replaced to avoid the scraping effect of the scraper 210 being reduced due to wear on the surface of the scraper 210 due to long-term operation, thereby affecting the scraping of the material stuck inside the reactor body 1. By providing the mounting bolts 6, the box door 5 can be installed to facilitate the maintenance of the components in the inner cavity of the reactor body 1. By providing the anchor bolts 9, the entire equipment can be stabilized to avoid the entire equipment from tipping over due to accidental collision, which affects the stirring of the urea resin.

At this time, the stirring tube 202 drives the stirring rod 207 and the stirring blade 208 to rotate in the circumferential direction. At the same time, as the connecting rod 204 rotates, the active bevel gear 205 rotates synchronously with the connecting rod 204. As the active bevel gear 205 rotates, the driven bevel gear 206 cooperates with it and causes the stirring rod 207 to rotate. As the stirring rod 207 rotates, the stirring blade 208 rotates synchronously, thereby starting to stir the material in the inner cavity of the reactor body 1. When the urea resin is stirred, it is discharged through the discharge valve 4 to complete the stirring of the urea resin.
