Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0014] Please refer to Figures 1-2 , in the embodiment of the present utility model, a grinding device for chemical raw materials used in the chemical industry includes a cover 1, a surrounding sleeve 2, a driving gear 3, a driving motor 4, a crushing bin 5, a water bath tank 6, a temperature control device 7, a grinding hammer 8, a plain bearing 9, a vacuum cleaner 10, a dust collection bin 11, a dust collection bag 12, a driven gear ring 13, a cover plate 14 and a conduit 15;

[0015] The top of the crushing bin 5 is open and the outer surface is welded with a driven gear ring 13. The lower end surface of the driven gear ring 13 is used to be placed on the upper end surface of the plain bearing 9, and the lower end surface of the plain bearing 9 is fixedly installed on the bracket welded to the inner wall of the housing 21, so that the crushing bin 5 has a basic structure for rotation;

[0016] The driven gear ring 13 is meshed and connected to the driving gear 3. The driving gear 3 is fixedly connected to the power output shaft of the driving motor 4. The driving motor 4 is fixedly connected to the outer surface of the housing 21 by bolts. The crushing chamber 5 is rotated by the driving motor to cooperate with the relatively stationary grinding hammers 8 to grind chemical raw materials.

[0017] At a position near the bottom end face inside the crushing chamber 5, there are grinding hammers 8. The grinding hammers 8 are arranged close to the bottom surface of the crushing chamber 5 (they can be in contact). The bottom of the grinding hammers 8 is arc-shaped, which is convenient for squeezing the raw materials to be ground during movement. The relative movement between the two realizes the squeezing and grinding of the particulate matter between the two.

[0018] One end of the connecting rod of the grinding hammer 8 is connected, and the other end of the connecting rod is connected to the inner wall of the surrounding sleeve 2. The surrounding sleeve 2 is sleeved around the periphery of the opening of the crushing chamber 5. At the same time, the top of the surrounding sleeve 2 is connected to a cover 1. The top of the cover 1 is connected to the air inlet on the cover plate 14 through a conduit 15. The cover plate 14 covers the top port of the dust collection chamber 11. The bottom air outlet of the dust collection chamber 11 is connected to the air extraction end of the vacuum cleaner 10. A dust collection bag 12 is arranged in the dust collection chamber 11. The bag mouth of the dust collection bag 12 is turned over and sleeved on the opening edge of the dust collection chamber 11. That is, the vacuum cleaner generates suction, so that the air flow enters from the gap between the surrounding sleeve 2 and the outer wall of the crushing chamber 5, and then drives the agitated dust into the integrated bag.

[0019] One end of a guide rod 20 is welded to the outer surface of the cover 1. The vertical section of the guide rod 20 is slidably arranged on the guide rod bracket 16. The guide rod bracket 16 is welded to the outer surface of the crushing chamber 5. A baffle 18 is welded at a position above the guide rod bracket 16 on the vertical section of the guide rod 20. A spring 19 is arranged between the baffle 18 and the guide rod bracket 16. One end of a screw rod 17 is rotatably connected to the baffle 18 through a bearing. The screw rod 17 is threadedly connected to a threaded through hole correspondingly opened on the guide rod bracket 16. One end of the screw rod 17 can also be connected with a handle, so that the operator can manually lift the corresponding cover 1 by rotating the handle. When the screw rod 17 is disengaged from the threaded hole, the guide rod 20 can also be rotated to deviate the cover, which is convenient for removing the crushing chamber 5.

[0020] The bottom of the crushing chamber 5 is arranged in a water bath tank 6. The bottom of the water bath tank 6 is in contact with the heat exchange unit of the temperature control device 7. The temperature control device 7 can be a semiconductor refrigeration sheet and the switch and battery connected thereto. The refrigerating end of the semiconductor refrigeration sheet is in contact with the bottom of the water bath tank 6 to keep the low temperature during grinding, or the heating end is in contact with the bottom of the water bath tank 6 for heating to avoid too low temperature, which is suitable for the grinding of chemical raw materials. The temperature control can be adjusted manually, that is, the operator uses a temperature measuring gun to measure the temperature, and then makes the semiconductor refrigeration sheet work by turning on and off the switch to realize the approximate adjustment of the temperature.

[0021] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
