DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments.

[0030] In one embodiment, referring to Figures 1 to 7 A raw material crushing device for producing powdered choline chloride, comprising a barrel 1, a discharging pipe 3 arranged at the bottom of the barrel 1, a feeding hopper 2 arranged at the top of the barrel 1, a screening mesh plate 12 arranged inside the barrel 1, a mounting seat 13 arranged inside the barrel 1, a rotating rod two 10 movably mounted at the top of the mounting seat 13, a rotating rod one 8 mounted at the top end of the rotating rod two 10 through a transmission 9, a crushing rod 11 arranged at one end of the rotating rod two 10 extending to the top of the screening mesh plate 12, and a driving motor 14 arranged at the bottom of the mounting seat 13 for driving the rotating rod two 10 to rotate; a stirring mechanism 15 arranged at the circumference of the rotating rod one 8 for stirring the raw material at the circumference of the screening mesh plate 12 to the middle of the top of the screening mesh plate 12; the stirring mechanism 15 comprises a rotating seat 154 mounted at the circumference of the rotating rod one 8, a rotating rod three 151 movably mounted on the rotating seat 154 in a ring shape, a stirring part 152 arranged at one end of the rotating rod three 151 close to the screening mesh plate 12, a driven gear 153 arranged at the circumference of the rotating rod three 151, a fixed gear ring 155 mounted on the inner circumferential wall of the barrel 1, and the inner wall of the fixed gear ring 155 and the circumference of the driven gear 153 being engaged; a cooling mechanism 4 arranged at the bottom of the screening mesh plate 12 for blowing air to the bottom of the screening mesh plate 12 during the crushing process.

[0031] In use, the raw materials to be pulverized are fed into the barrel 1 through the feeding hopper 2, the driving motor 14 drives the rotating rod two 10 and the rotating rod one 8 to rotate, the crushing rod 11 pulverizes the raw materials falling on the screening mesh plate 12, at the same time, the cooling mechanism 4 blows air to the bottom of the screening mesh plate 12 to dredge the mesh holes on the screening mesh plate 12 and blow the raw materials on the screening mesh plate 12 to dissipate heat, so as to avoid the case that the temperature of the raw materials is too high during the pulverization, when the rotating rod one 8 drives the rotating seat 154 and the rotating rod three 151 to rotate horizontally, the rotating rod three 151 also rotates due to the meshing of the driven gear 153 and the fixed gear ring 155, the rotating rod three 151 drives the material stirring part 152 to stir the raw materials at the top circumference of the screening mesh plate 12, so that the raw materials are stirred to fully contact with the crushing rod 11, so as to ensure that the raw materials on the screening mesh plate 12 can be effectively pulverized fully and comprehensively, improve the pulverization efficiency, and the pulverized raw materials are discharged from the discharge pipe 3 after being screened by the screening mesh plate 12.

[0032] As a preferred embodiment of the present application, the cross section of the material stirring part 152 is C-shaped structure, which can better contact with the raw materials during work, so as to ensure that the raw materials can be smoothly stirred to the middle part of the screening mesh plate 12, effectively improve the pulverization efficiency, the side of the material stirring part 152 away from the rotating rod three 151 abuts against the inner wall of the barrel 1, through this design, the working position of the material stirring part 152 is further stabilized, so as to prevent deviation or failure caused by high-speed operation, ensure the accuracy and continuity of the stirring action, and ensure that the material stirring part 152 can stir the raw materials close to the inner wall of the barrel 1, in addition, the material stirring part 152 is made of flexible material, which can avoid damaging the screening mesh plate 12 or the inner wall of the barrel 1 when contacting with the raw materials, effectively adapt to raw materials of different particle sizes, play a buffering role, reduce the impact force, improve the durability and service life of the equipment, at the same time, the flexible material can reduce powder splashing during the pulverization and stirring process, improve the cleanliness of the working environment, and ensure the stability of the equipment operation.

[0033] As a preferred embodiment of the present application, the cooling mechanism 4 includes a gas pump 42 installed on the outer wall of the barrel 1, one end of the rotating rod two 10 located at the bottom of the screening mesh plate 12 is provided with an air outlet shell 44, the side of the air outlet shell 44 close to the screening mesh plate 12 is provided with an air outlet hole 43, the air outlet end of the gas pump 42 is communicated with the inside of the air outlet shell 44 through the extension air pipe 41, cold air can be injected into the air outlet shell 44 through the gas pump 42 and the extension air pipe 41, and the cold air is sprayed to the bottom of the screening mesh plate 12 from the air outlet hole 43.

[0034] As a preferred embodiment of the present application, the rotating part 7 is installed at the circumference of the rotating rod 8, and is designed as a double-cone-cylinder structure with conical ends and a cylindrical middle part. This structure not only has good mechanical stability, but also effectively guides the movement trajectory of the raw materials during operation, reducing the accumulation and blockage of the materials. A gap is left between the circumference of the rotating part 7 and the inner wall of the barrel 1, which provides a channel for the sliding of the raw materials and the flow of the hot air, facilitating the smooth progress of the crushing and drying processes.

[0035] The rotating part 7 is provided with movable raking rods 18 at its circumference, which are staggered with the fixed rods on the inner wall of the barrel 1. When the rotating part 7 rotates with the rotating rod 8, the staggered movement of the movable raking rods 18 and the fixed rods forms a periodic blocking and raking action, which can effectively disturb the raw materials that slide in the gap, delay the falling rate of the raw materials, and increase the residence time of the raw materials in the gap. This design not only prevents the accumulation or blockage of the raw materials in the gap, but also promotes the sufficient contact between the raw materials and the hot air, achieving a higher drying effect.

[0036] In addition, the bottom circumference of the rotating part 7 is provided with annularly distributed air guide grooves 21 for guiding the hot air after heat exchange to the circumference of the rotating part 7. This design allows the hot air to be evenly distributed to the gap area along the air guide grooves, quickly and comprehensively drying the falling raw materials. At the same time, during the rotation of the rotating part 7, the movable raking rods 18 can also stir the hot air in the gap while raking the raw materials, further enhancing the contact area and heat exchange efficiency between the hot air and the raw materials, accelerating the drying process of the raw materials.

[0037] Overall, through the double-cone-cylinder structure design of the rotating part 7, the cooperation of the movable raking rods 18 and the fixed rods, and the guidance and distribution of the air guide grooves 21 to the hot air, the equipment can not only effectively avoid the accumulation and blockage of the raw materials, but also improve the drying effect and crushing efficiency, ensuring the uniformity and efficiency of the raw materials during the crushing process. At the same time, the design of this structure also improves the stability and continuous working performance of the equipment, which is suitable for high-strength industrial production needs.

[0038] As a preferred embodiment of the present application, the circumferential inner wall of the barrel 1 movably installs the spacedly distributed movable guide net plate one 16 and the movable guide net plate two 20, the movable guide net plate two 20 is located at the top of the gap between the adjacent two movable guide net plate one 16, which ensures that the raw materials can smoothly transition and flow during falling, the bottom of the movable guide net plate two 20 and the top of the movable guide net plate one 16 are connected by springs, so that they have a certain elasticity and activity between them, effectively buffering the impact force of the falling raw materials, preventing excessive accumulation of materials, the movable guide net plate two 20 and the movable guide net plate one 16 are located between the rotating part 7 and the fixed gear ring 155, the movable guide net plate two 20 and the movable guide net plate one 16 are both arc-shaped structures, the inner arc surface of the movable guide net plate two 20 and the movable guide net plate one 16 is the side close to the rotating part 7, which is used for transition and guide of the falling raw materials at the circumference of the rotating part 7, and also avoids the raw materials from falling and accumulating on the fixed gear ring 155, which affects the effective engagement of the fixed gear ring 155 and the driven gear 153; the outer arc surface of the movable guide net plate one 16 is provided with a limiting protrusion 19 for limiting the downward turning of the movable guide net plate one 16, the bottom of the movable guide net plate one 16 is provided with a protruding part, the top end of the rotating rod three 151 is provided with a jacking part 17, the position of the jacking part 17 corresponds to the position of the protruding part, when the rotating rod three 151 rotates horizontally, the jacking part 17 reciprocally jacks the protruding part, so that the movable guide net plate one 16 and the movable guide net plate two 20 reciprocally swing up and down under the jacking action, under the reciprocating jacking action, the movable guide net plate one 16 and the movable guide net plate two 20 continuously shake the raw materials falling thereon, effectively preventing the raw materials from sticking or accumulating, while increasing the flowability and dispersibility of the raw materials on the net plate. This swinging design helps to improve the drying effect of the raw materials, so that the hot air flow can pass through the raw materials more uniformly, ensuring that the raw materials are evenly heated during drying, and further improving the drying efficiency. In addition, this design can also avoid the raw materials from stagnating on the net plate for a long time, thereby ensuring the continuity and stability of the overall crushing and drying process.

[0039] As a preferred embodiment of the present application, a gas guide cover 6 is installed at the top of the barrel 1, which is located at the top of the rotating part 7, used for guiding the hot air flow flowing to the top of the rotating part 7, ensuring that the hot air flow contacts and preheats the raw materials falling from the top of the rotating part 7, improving the drying efficiency of the raw materials.

[0040] As a preferred embodiment of the present application, the end of the rotating rod one 8 extending into the feeding hopper 2 is provided with a pre-crushing rod 5 for pre-crushing the raw materials fed.
