Description

Technical Field

[0001] This utility model relates to the field of 4-methylimidazole production technology, and in particular to a chemical cooling granulation device. Background Technology

[0002] 4-Methylimidazole is a heterocyclic organic compound. When 4-methylimidazole is produced, the finished product is a liquid at 80°C. The liquid is directly packaged into 25KG cardboard drums with packaging bags. When the liquid temperature drops to 40°C, the material will solidify into a solid.

[0003] In actual production, due to the low ambient temperature, the outer layer of the material solidifies first inside the cardboard drum. After the outer layer solidifies, the temperature of the center of the material drops more slowly, resulting in a reddish color in the center of the material. For example, the existing Chinese patent announcement number "CN114276299B" discloses a continuous preparation method of 4-methylimidazole, which includes the following steps: providing a channel reactor; introducing liquid ammonia into the channel reactor; and introducing hydroxyacetone and formamide into the channel reactor, with the reaction mixture residing in the channel reactor for 3-10 minutes.

[0004] In practice, due to the low outside temperature, the outer layer of the material solidifies first inside the cardboard drum. After the outer layer solidifies, the temperature in the center of the material drops more slowly, causing the center of the material to turn reddish, which affects the sale of the material. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where the quality of the 4-methylimidazole fraction is poor, and to propose a chemical cooling granulation device.

[0008] The filter unit includes a fixing part and a connecting part. The fixing part is fixedly connected to the end opening of the connecting pipe by a locking assembly. The fixing part is also detachably connected to the connecting part by the locking assembly and a filter element.

[0009] Furthermore, the locking assembly includes a slot, one end of the fixing part is recessed and provided with the filter element, and at least one pair of slots are distributed circumferentially on the outer wall of the recessed end of the fixing part. The slots are L-shaped and extend downward at the end to form a groove.

[0010] Furthermore, one end of the connecting part is slidably inserted into the end recess of the fixing part, and a support rod is also provided on the periphery of the connecting part at the insertion end. The support rod is correspondingly provided with the slot and slidably connected. Rotating the connecting part drives the support rod to stop in the slot.

[0011] The connecting part is provided with multiple filter grooves around its periphery, and the connecting part covers the periphery of the filter element.

[0012] Furthermore, the locking assembly also includes a locking member, which is rotatably connected to the outer wall of the connecting pipe, and the locking member has an arc groove on one side of the rotating shaft at both ends.

[0013] Furthermore, the free end of the support rod is provided with an annular groove, and the locking member is slidably connected to the annular groove through the arc groove. The end of the locking member is stopped in the annular groove, wherein flipping the locking member drives the support rod to be stopped in the groove.

During the spraying process, the material will also encounter the cold air blown out by the blowing unit 3, and then the liquid material will form particles. The specific operation is the prior art and will not be described in detail here.

[0026] The blowing unit 3 includes a blower, and the output and input ends of the blower are connected to the interior of the granulation chamber 1 through the connecting pipe 4.

[0027] It should be added that the top of the granulation chamber 1 is detachably connected to a cover plate by locking bolts, and the filter element 53 can be cleaned or replaced by removing the cover plate.

[0028] Furthermore, the locking assembly 6 includes a slot 61, one end of the fixing part 51 is recessed and provided with the filter element 53, and at least one pair of slots 61 are distributed circumferentially on the outer wall of the recessed end of the fixing part 51. The slots 61 have an L-shaped structure and extend downward at the end to form a groove 62.

[0029] Furthermore, one end of the connecting part 52 is slidably inserted into the end recess of the fixing part 51. The connecting part 52 is also provided with a support rod 54 on the periphery of the insertion end. The support rod 54 is correspondingly provided with the slot 61 and slidably connected. Rotating the connecting part 52 drives the support rod 54 to stop in the slot 61.

[0030] The connecting part 52 is provided with multiple filter grooves around its periphery, and the connecting part 52 covers the periphery of the filter element 53.

[0031] It should be added that the filter element 53 can be a filter cotton core or a cylindrical filter screen. Specifically, the connecting part 52 filters large particles that may be mixed in the recovered blower through the filter groove on the outer wall, while the filter element 53 is used to filter fine particles to prevent particles from affecting the normal operation of the blower.

[0032] More specifically, the two ends of the filter element 53 abut against the inner walls of the fixing part 51 and the connecting part 52, respectively. The fixing part 51 and the connecting part 52 close together to fix the filter element 53.

[0033] More specifically, the locking assembly 6 also includes a locking member 63, which is rotatably connected to the outer wall of the connecting pipe 4, and the locking member 63 has an arc groove 64 on one side of the rotating shaft at both ends.

[0035] The fixing part 51 engages with the open end of the connecting pipe 4 located inside the granulation chamber 1, and the fixing part 51 abuts against the protruding part of the inner wall of the end of the connecting pipe 4.

[0036] Finally, an elastic claw 65 is provided on the outer wall of the connecting pipe 4, and the snap-fit ​​end of the elastic claw 65 snaps into the slot on the outer wall of the locking member 63.

[0037] In this embodiment, the locking member 63 locks the support rod 54 through the arc groove 64 and the annular groove 541, which can be referred to in the prior art high voltage connector structure.

[0038] In the initial state, the locking member 63 disengages from the elastic claw 65 and flips over. At this time, the opening of the arc groove 64 corresponds to the ring groove 541. When the fixing part 51 and the connecting part 52 are inserted, the support rod 54 is slidably connected in the arc groove 64 through the ring groove 541.
