Abstract
Description
Technical Field
[0001] This utility model relates to the field of chemical material processing technology, and in particular to a grinding device for chemical raw materials. Background Technology
[0002] Some chemical raw materials may clump before being used in production. There are two ways to handle clumped raw materials before use: One is to manually break up the clumps when the input quantity is small. This method is not only labor-intensive and time-consuming, but also results in uneven particle size, with some small clumps remaining, affecting subsequent production. The second method is to use a crusher for real-time crushing when the input quantity is large. However, the crusher's rotation only breaks the material into small pieces, leaving some small clumps that cannot be directly used in production. This requires further processing, increasing production steps and reducing efficiency. Utility Model Content
[0003] The purpose of this invention is to provide a grinding device for chemical raw materials. Regardless of the amount of raw materials input, it can grind agglomerated chemical raw materials and restore them to their original particle size in one go, thereby meeting production needs, saving manpower, and improving production efficiency.
[0004] To achieve the above objectives, this utility model provides a grinding device for chemical raw materials, including a grinding barrel. The grinding barrel includes a barrel wall, a base disposed at the bottom of the barrel wall, and a barrel cover disposed at the top of the barrel wall. The barrel cover, barrel wall, and base form a grinding chamber. The top of the grinding barrel is provided with a feed inlet, and the bottom is provided with a powder outlet. The grinding chamber is divided into an upper and lower adjacent coarse powder chamber and a fine powder chamber. The feed inlet is connected to the coarse powder chamber, and the powder outlet is connected to the fine powder chamber. The coarse powder chamber and the fine powder chamber are connected through a grinding port. A grinding device is installed on the grinding port.
[0005] With the above structure, the raw materials are poured into the grinding barrel from the feed inlet. The materials are first stored in the coarse powder chamber. As the grinding device is started, the raw materials that have been ground by the grinding device fall into the fine powder chamber, thereby realizing the grinding of agglomerated chemical raw materials. Only the raw materials that have been ground to the required standard can fall into the fine powder chamber, thereby restoring them to their original particle size in one go, meeting production needs, saving manpower, and improving production efficiency.
[0006] Preferably, the grinding device includes a grinding disc with a grinding cavity in the middle and a grinding head inserted into the grinding cavity and capable of rotating within the grinding cavity; the grinding disc is fixed on the grinding port, and the grinding cavity inside it has an annular structure; the grinding head includes a conical head disposed in the grinding cavity, a rotating shaft rotatably mounted on the lid of the grinding barrel with its bottom fixed at the minimum diameter of the conical head, and a drive device that drives the rotating shaft to rotate; a preset gap is provided between the maximum diameter of the bottom of the conical head and the grinding cavity. With this design, the drive device drives the conical head to rotate at high speed in the grinding cavity, while the grinding disc remains stationary; as it rotates, the conical head breaks up the agglomerated raw materials, and the broken raw materials fall from the gap between the conical head and the grinding cavity.
[0007] Preferably, the inner surface of the grinding chamber is uniformly covered with inner grinding teeth; the outer surface of the conical head is uniformly covered with outer grinding teeth. The arrangement of the inner and outer grinding teeth ensures that the raw material is subjected to extremely high shear and frictional forces during rotation, thereby dispersing it.
[0008] Preferably, the internal grinding teeth include coarse grinding teeth evenly distributed above the grinding cavity and fine grinding teeth evenly distributed below the grinding cavity; the tips of the coarse grinding teeth face the opposite direction of the rotation direction of the conical head, and their tooth height gradually decreases from top to bottom; the tooth pitch of the fine grinding teeth is smaller than that of the coarse grinding teeth. With this design, by setting relatively protruding coarse grinding teeth above the grinding cavity, their tips can collide and crush the raw material, while the fine grinding teeth below facilitate further grinding and crushing of the raw material's particle size, ensuring that the final ground raw material particle size meets production requirements.
[0009] Preferably, the tips of the external grinding teeth spiral downwards along the generatrix of the conical head, with the spiral direction being the same as the rotation direction of the conical head. This design allows the conical head to create a downward guiding effect during rotation, preventing raw materials from accumulating in the coarse powder cavity.
[0010] Preferably, the grinding head also includes a shift gear fixed to the rotating shaft and located at the top of the conical head; the shift gear includes a toothed disc fixed to the rotating shaft and toothed hooks evenly distributed around the periphery of the toothed disc and extending outward from the toothed disc. This design prevents the material from accumulating above the conical head.
[0011] Preferably, four toothed hooks are provided. Four toothed hooks can ensure sufficient tooth spacing, which can increase the frequency of contact with the raw material, while avoiding the situation where the raw material cannot fall due to insufficient tooth spacing.
[0012] Preferably, the inner wall of the coarse powder chamber has a conical structure, with a grinding port at the smallest diameter of its bottom; the bottom of the fine powder chamber has a conical bottom, with a powder outlet at the smallest diameter of its bottom. This design facilitates the falling of raw materials and the discharge of fine powder.
[0013] Preferably, a switch door is installed on the feed inlet. By installing a switch door on the feed inlet, the raw materials are prevented from flying out during the grinding process.
[0014] Preferably, the barrel lid has a shaft hole on one side of the feed inlet, and a pressure plate with its opening facing outwards from the feed inlet on the opposite side; a pin is provided on one side of the switch door corresponding to the shaft hole, and the pin can be inserted into the shaft hole and rotated within it; when the switch door rotates, its side away from the pin can be inserted into the bottom of the pressure plate and pressed down by the pressure plate; a lever is provided on the switch door, which can rotate the switch door out of the pressure plate. This design facilitates the opening and closing of the switch door.
[0015] After adopting the above technical solution, the beneficial effects of this utility model are:
[0016] This utility model provides a grinding device for chemical raw materials, which solves the technical problem in the prior art that chemical raw materials are clumped together and cannot be used directly, while secondary processing is inefficient and has poor processing effect. Regardless of the amount of raw materials input, this utility model can grind agglomerated chemical raw materials and restore them to their original particle size in one go, meeting production needs, saving manpower, and improving production efficiency.

[0024] The present invention will be further described below with reference to the accompanying drawings.
[0025] The orientations mentioned in this specification are based on the orientation of the grinding device for chemical raw materials of this utility model when it is working normally. They do not limit the orientation during storage and transportation, and only represent relative positional relationships, not absolute positional relationships.
[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a grinding device for chemical raw materials includes a grinding barrel 1. The grinding barrel 1 includes a circular barrel wall 11, a base 12 disposed at the bottom of the barrel wall 11, and a barrel cover 13 disposed at the top of the barrel wall 11. The barrel cover 13, the barrel wall 11, and the base 12 form a coarse powder chamber. The barrel cover 13 is provided with a feed inlet 131, and the base 12 is provided with a powder outlet 121.
[0027] like Figure 6 As shown, a switch door 16 is installed on the feed inlet 131; a shaft hole is provided on one side of the barrel cover 13 located at the feed inlet 131, and a pressure plate 161 with its opening facing the outside of the feed inlet 131 is provided on the opposite side; a pin 162 is provided on one side of the switch door 16 corresponding to the shaft hole, and the pin 162 can be inserted into the shaft hole and rotated in the shaft hole; when the switch door 16 rotates, the side of it located away from the rotating shaft 222 can be inserted into the bottom of the pressure plate 161 and pressed by the pressure plate 161; a lever 163 is provided on the switch door 16, and the lever 163 can rotate the switch door 16 out of the pressure plate 161.
[0028] The coarse powder chamber is divided into an adjacent coarse powder chamber 14 and a fine powder chamber 15. The feed inlet 131 is connected to the coarse powder chamber 14, and the powder outlet 121 is connected to the fine powder chamber 15. The coarse powder chamber 14 and the fine powder chamber 15 are connected by a grinding port; a grinding device 2 is installed on the grinding port.
[0029] like Figure 2 , Figure 3 and Figure 4 As shown, the grinding device 2 includes a grinding disc 21 with a grinding cavity 211 in the middle and a grinding head 22 that is inserted into the grinding cavity 211 and can rotate within the grinding cavity 211. Both the grinding disc 21 and the grinding head 22 are made of high-strength stainless steel; the material is corrosion-resistant and wear-resistant.
[0030] The grinding disc 21 is fixed to the grinding port, and the grinding cavity 211 inside it has an annular structure. The grinding head 22 includes a conical head 221 disposed in the grinding cavity 211, a rotating shaft 222 rotatably mounted on the cover 13 of the grinding barrel 1 with its bottom fixed at the minimum diameter of the conical head 221, and a drive device 223 that drives the rotating shaft 222 to rotate; the drive device 223 is a motor, which is fixed to the outside of the cover 13 by a flange, and its output shaft is driven by the rotating shaft 222. A preset gap is provided between the maximum diameter of the bottom of the conical head 221 and the grinding cavity 211.
[0031] The drive device 223 drives the conical head 221 to rotate at high speed in the grinding cavity 211, while the grinding disc 21 remains stationary. As it rotates, the conical head 221 breaks up the agglomerated raw material, and the broken raw material falls from the gap between the conical head 221 and the grinding cavity 211.
[0032] Furthermore, to improve the dispersing effect, the inner surface of the grinding cavity 211 is evenly covered with inner grinding teeth; the outer surface of the conical head 221 is evenly covered with outer grinding teeth. The arrangement of inner and outer grinding teeth ensures that the raw material is subjected to great shearing and frictional forces during rotation, thereby dispersing it.
[0033] The internal grinding teeth include coarse grinding teeth 212 evenly distributed above the grinding cavity 211 and fine grinding teeth 213 evenly distributed below the grinding cavity 211. The tips of the coarse grinding teeth 212 face the opposite direction of rotation of the conical head 221, and their tooth height gradually decreases from top to bottom. The tooth pitch of the fine grinding teeth 213 is smaller than that of the coarse grinding teeth 212. This structure ensures that during the grinding process, the raw material first contacts and collides with the coarse grinding teeth 212, reducing its particle size and facilitating downward transport. Then, it contacts the fine grinding teeth 213. The increased number of teeth in the fine grinding teeth 213 maximizes the number of collisions with the raw material, thereby maximizing the grinding of the raw material.
[0034] like Figure 2 , Figure 3 and Figure 5 As shown, the tips of the external grinding teeth spiral downwards along the generatrix of the conical head 221, and their rotation direction is the same as that of the conical head 221. By providing spirally downward-facing external grinding teeth on the upper surface of the conical head 221, the material above can be guided downwards when the conical head 221 rotates, thus preventing the material from accumulating in the coarse powder chamber 14. Under the conveying action of the conical head 221, the material is gradually squeezed downwards, and the gap between the conical head 221 and the grinding chamber 211 gradually decreases, thereby grinding and dispersing the agglomerated material. The material passing between the tooth surfaces is subjected to great shearing and frictional forces, and under the action of complex forces such as high-frequency vibration and high-speed vortex, the material is effectively dispersed, crushed, and homogenized.
[0035] To agitate the material within the coarse powder chamber and prevent it from becoming stuck, the grinding head 22 also includes a gear 224 fixed to the rotating shaft 222 and located at the top of the conical head 221. The gear 224 includes a toothed disc fixed to the rotating shaft 222 and toothed hooks evenly distributed around the toothed disc and extending outwards. The rotation of the gear 224 agitates the raw material above the conical head 221, thereby effectively dispersing and pulverizing the material.
[0036] Furthermore, four toothed hooks are provided. Four toothed hooks can ensure sufficient tooth spacing, which can increase the frequency of contact with the raw material, while avoiding the situation where the raw material cannot fall due to insufficient tooth spacing.
[0037] To facilitate the falling of raw materials, the inner wall of the coarse powder chamber has a conical structure, with a grinding port at the smallest diameter at the bottom.
[0038] To facilitate the discharge of fine powder, the bottom of the fine powder chamber is conical, with a powder outlet 121 opened at the minimum diameter of the bottom.
[0039] This utility model provides a grinding device for chemical raw materials, which solves the technical problem in the prior art that chemical raw materials are clumped together and cannot be used directly, while secondary processing is inefficient and has poor processing effect. Regardless of the amount of raw materials input, this utility model can grind agglomerated chemical raw materials and restore them to their original particle size in one go, meeting production needs, saving manpower, and improving production efficiency.
[0040] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
