[0021] Please refer to Figures 1-4 , the present utility model discloses a chemical material screening machine for chemical industry, including a screening shell 1. A screen frame 2 is arranged inside the screening shell 1. Mounting seats 3 are movably arranged on both sides of the screen frame 2. Mounting plates 201 are fixedly arranged on both sides of the screen frame 2. One side of the mounting plate 201 is slidably connected to the mounting through groove on one side of the mounting seat 3. A jack is opened inside the mounting plate 201, and a limiting rod 301 is movably arranged inside the jack. The limiting rod 301 is L-shaped, and one end of the limiting rod 301 is fixedly provided with a nut seat 302;

[0022] One side of the nut seat 302 is fixedly provided with a guide block 305. One end of the guide block 305 is slidably connected to the chute on one side of the inner wall of the mounting seat 3. A lead screw 303 is movably arranged inside the inner wall of the nut seat 302. The connection relationship between the lead screw 303 and the nut seat 302 is a threaded connection. One end of the lead screw 303 penetrates through the bottom of the inner wall of the mounting seat 3 and extends to the bottom of the outer wall of the mounting seat 3. One end of the lead screw 303 is fixedly provided with a turning handle 304. A connecting slide bar 4 is fixedly arranged on one side of the mounting seat 3.

[0023] Specifically, support plates 202 are fixedly arranged on both sides of the inner wall of the screen frame 2, and a screen mesh 203 is arranged on the top of the support plates 202.

[0024] In this implementation scheme, by setting the screen mesh 203, the screen holes on the screen mesh 203 can screen the chemical materials.

[0025] Specifically, the screen 203 is movably connected to the support plate 202 by bolts 204. Threaded holes adapted to the bolts 204 are provided at the top of the support plate 202, and the connection between the bolts 204 and the support plate 202 is a threaded connection.

[0026] In this embodiment, by setting the bolts 204, loosening the bolts 204 allows the bolts 204 to be removed from the threaded holes in the support plate 202, and then the screen 203 can be disassembled, thus realizing the detachable function of the screen 203 and facilitating the replacement of the screen 203.

[0027] Specifically, a connecting plate 401 is fixedly provided at one end of the connecting slide rod 4. A spring 402 is sleeved on the outer side of the connecting slide rod 4. A cam 5 is movably provided on one side of the connecting plate 401. A rotating shaft 501 is fixedly provided at the bottom of the cam 5, and one end of the rotating shaft 501 is fixedly connected to the output shaft of the motor 502.

[0028] In this embodiment, by setting the spring 402, the cam 5 and the motor 502, the motor 502 drives the cam 5 to rotate. The rotating cam 5 repeatedly presses the connecting plate 401. Under the elastic force of the connecting spring 402, the screen frame 2 and the screen 203 will reciprocate and shake, thereby vibrating and screening the chemical materials.

[0029] Specifically, a maintenance door 6 is connected to the front of the screening shell 1 by a hinge.

[0030] In this embodiment, by setting the maintenance door 6, opening the maintenance door 6 allows the components inside the screening shell 1 to be repaired and maintained.

[0031] Specifically, the connection between the limiting rod 301 and the mounting plate 201 is a movable insertion.

[0032] In this embodiment, by setting the limiting rod 301, rotating the turning handle 304 drives the lead screw 303 to rotate. The rotating lead screw 303 drives the limiting rod 301 to move vertically through the nut seat 302. When one end of the limiting rod 301 is inserted into the jack on the mounting plate 201, the mounting plate 201 can be limited.

[0033] During use, start the motor 502. The motor 502 drives the cam 5 to rotate. The rotating cam 5 repeatedly presses the connecting plate 401. Under the elastic force of the connecting spring 402, the screen frame 2 and the screen 203 will reciprocate and shake. Then, the chemical materials are put into the interior of the screening shell 1, and the reciprocatingly shaking screen 203 can vibrate and screen the chemical materials.

[0034] When disassembling the sieve frame 2, rotate the turning handle 304 to drive the lead screw 303 to rotate. The rotating lead screw 303 drives the limit rod 301 to move vertically through the nut seat 302. When one end of the limit rod 301 is removed from the jack on the mounting plate 201, the limit on the mounting plate 201 can be released, and then the sieve frame 2 can be disassembled;

[0035] When installing the sieve frame 2, insert the mounting plates 201 on both sides of the sieve frame 2 into the mounting through grooves on the two mounting seats 3 respectively, and then rotate the turning handle 304 to drive the lead screw 303 to rotate. The rotating lead screw 303 drives the limit rod 301 to move vertically through the nut seat 302. When one end of the limit rod 301 is inserted into the jack on the mounting plate 201, the mounting plate 201 can be limited, and then the installation of the sieve frame 2 is realized;

[0036] When disassembling the sieve mesh 203, set the bolt 204 and loosen the bolt 204 so that the bolt 204 is removed from the threaded hole on the support plate 202, and then the sieve mesh 203 can be disassembled. When installing the sieve mesh 203, place the sieve mesh 203 on the support plate 202 in the sieve frame 2, then insert and tighten the bolt 204. When one end of the bolt 204 is completely screwed into the threaded hole on the support plate 202, the installation of the sieve mesh 203 is completed.

[0037] In summary, for this chemical material screening machine for chemical industry, by setting the mounting seat 3, limit rod 301, nut seat 302, lead screw 303 and turning handle 304, rotate the turning handle 304 to drive the lead screw 303 to rotate. The rotating lead screw 303 drives the limit rod 301 to move vertically through the nut seat 302. When one end of the limit rod 301 is removed from the jack on the mounting plate 201, the limit on the mounting plate 201 can be released, and then the sieve frame 2 can be disassembled, thus realizing the detachable function of the sieve frame 2, which is convenient for cleaning and maintenance of the sieve frame 2. Tools are not required during the disassembly process, the time spent on disassembly is relatively short, and the disassembly efficiency is high.
