For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0030] As Figures 1-5 shown, a chemical raw material vibration screening device proposed by the present utility model includes a screening bin 1;

[0031] A control panel 2 is arranged on the front of the screening bin 1. A bin door 3 is hinged on the front of the screening bin 1 through a hinge. A screening member 4 for screening chemical raw materials is arranged on the screening bin 1.

[0032] In the present utility model, the chemical raw materials put into the screening bin 1 can be vibrationally broken and screened by the screening member 4, and the materials that are not screened and filtered can be discharged by opening the bin door 3.

[0033] In an alternative embodiment, the screening member 4 includes a driving motor 41 fixedly connected to the front surface of the screening bin 1. There are two rotating shafts 44 rotatably connected to the inner side wall of the screening bin 1, and one end of each of the two rotating shafts 44 penetrates through the screening bin 1. The back surface of the screening bin 1 is fixedly connected with a mounting frame 43. The ends of the two rotating shafts 44 are both fixedly connected with gears 45 that mesh with each other and are located inside the mounting frame 43. A vibrating plate 42 whose one end penetrates through the screening bin 1 is slidably connected to the inside of the screening bin 1. A support plate 413 is fixedly connected to the inner side wall of the screening bin 1. A support rod 410 is fixedly connected to the support plate 413. A screening plate 48 is slidably connected to the support rod 410. A number of screening holes 49 are formed in the screening plate 48. A cam 415 located inside the screening bin 1 is fixedly connected to the rotating shaft 44. A return spring 411 is fixedly connected between the screening plate 48 and the support plate 413. A cross bar 46 whose one end penetrates through the screening bin 1 is fixedly connected to the inside of the vibrating plate 42. A support spring 47 is fixedly connected between the vibrating plate 42 and the screening bin 1.

[0034] In this embodiment, the vibrating vibrating plate 42 can extrude and crush the input materials for discharging. After the crushed materials fall onto the screening plate 48, they can be vibrated and screened by the vibrating screening plate 48, avoiding subsequent manual screening of the condensed blocky materials, so as to improve the screening efficiency of chemical raw materials and the screening efficiency.

[0035] It should be noted that one end of the right rotating shaft 44 is fixedly connected to the output shaft of the driving motor 41, so that the started driving motor 41 drives the right rotating shaft 44 to rotate. The rotating right rotating shaft 44 can drive the left rotating shaft 44 to rotate synchronously through the two meshing gears 45. The upper end of the vibrating plate 42 is L-shaped, and the L end of the vibrating plate 42 is inclined, so that the inclined part of the vibrating plate 42 can guide the materials. The driving motor 41 is electrically connected to the control panel 2, and the opening and closing of the driving motor 41 are controlled through the control panel 2.

[0036] Among them, the number of cams 415 is four, and the four cams 415 are symmetrically distributed in two groups on the two rotating shafts 44. Through the two groups of cams 415, the two vibrating plates 42 and the screening plate 48 can be stably extruded to drive the vibrating plates 42 and the screening plate 48 to vibrate.

[0037] In addition, a round hole located outside the cross bar 46 is formed in the inner side wall of the screening bin 1. The number of vibrating plates 42 is two, and the two vibrating plates 42 are symmetrically distributed inside the screening bin 1. The number of cross bars 46 is four, and the four cross bars 46 are symmetrically distributed in two groups on the two vibrating plates 42. A rectangular groove located outside the L end of the vibrating plate 42 is formed in the inner side wall of the screening bin 1, so that the vibrating plate 42 can vibrate stably on the screening bin 1. A rubber pad 414 is arranged on the inner side of the vibrating plate 42 to avoid hard contact between the vibrating plate 42 and the materials during vibration and reduce the possibility of material damage.

[0038] Secondly, a plurality of sieve holes 49 are distributed in a matrix on the screening plate 48. The material is vibrated and screened through the plurality of sieve holes 49. One end of the screening plate 48 close to the inner wall of the screening bin 1 is inclined, so that the inclined part of the screening plate 48 can guide the material. The bin door 3 and the screening plate 48 are on the same horizontal line. Support holes located outside the support rod 410 are formed in the screening plate 48. A material guide frame 412 with one end communicating with the sieve holes 49 is arranged at the lower end of the screening plate 48. The material guide frame 412 is in a square shape, so that the screened material is discharged through the material guide frame 412.

[0039] In an alternative embodiment, a feeding member 5 for material feeding is arranged at the upper end of the screening bin 1. The feeding member 5 includes a connecting frame 51 fixedly connected to one end of the upper end of the screening bin 1. A baffle 52 is fixedly connected to the inner side wall of the connecting frame 51. An adjusting plate 53 with one end penetrating through the connecting frame 51 is slidably connected to the inner side of the connecting frame 51. An adjusting screw 54 with one end penetrating through the connecting frame 51 is rotatably connected to the inner side of the adjusting plate 53. A limiting rod 55 with one end penetrating through the connecting frame 51 is fixedly connected to the inner side of the adjusting plate 53.

[0040] In this embodiment, since the rotating adjusting screw 54 can drive the adjusting plate 53 to move and adjust within the connecting frame 51, the feeding rate of the material can be adjusted by rotating the adjusting screw 54 to change the distance between the adjusting plate 53 and the baffle 52, further improving the material screening effect.

[0041] It should be noted that the inner sides of both the adjusting plate 53 and the baffle 52 are inclined, so that the inclined parts of the adjusting plate 53 and the baffle 52 guide the material. The upper end of the adjusting plate 53 is in an L shape. A threaded hole located outside the adjusting screw 54 is arranged on the inner side wall of the connecting frame 51. The thread on the outer side of the threaded hole is matched with the thread on the outer side of the adjusting screw 54, so that the rotating adjusting screw 54 can drive the adjusting plate 53 to stably move and adjust horizontally.

[0042] The working principle of the above embodiment is as follows:

[0043] Since the two sets of cams 415 are symmetrically distributed on the two rotating shafts 44, after the driving motor 41 starts to drive the right rotating shaft 44 to rotate, the left rotating shaft 44 can be driven to rotate synchronously through the two meshing gears 45. Then, the two sets of cams 415 can rotate. When the rotating cams 415 repeatedly press the vibrating plate 42 and the screening plate 48, the vibrating plate 42 and the screening plate 48 can be driven to vibrate repeatedly. Then, the chemical raw materials fed between the baffle 52 and the adjusting plate 53 will be pre-pressed and crushed by the two vibrating vibrating plates 42. After the agglomerated materials are crushed, they are guided to the screening plate 48, and then screened by the vibrating screening plate 48 through the sieve holes 49 and exported through the material guiding frame 412. The operator only needs to place the receiving box on the material guiding frame 412 to pick up the screened materials. At the same time, after opening the bin door 3, the unscreened materials can be picked up.

[0044] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
