DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 - Figure 7 As shown, a chemical raw material crushing device comprises a shell 1; a crushing box 2 is arranged inside the shell 1, a feeding bucket 19 is fixedly connected to the bottom of the crushing box 2, a fixing block Ⅰ3 is fixedly connected to the outside of the crushing box 2, and the fixing block Ⅰ3 is fixedly connected to the inner wall of the shell 1 away from the crushing box 2, a feeding pipe 31 is fixedly connected to the outside of the crushing box 2 near the top, the feeding pipe 31 is communicated with the inside of the crushing box 2, a discharge port 32 is fixedly connected to the top of the feeding pipe 31, a smoke exhaust pipe 33 is fixedly connected to the outside of the crushing box 2, the smoke exhaust pipe 33 is communicated with the inside of the crushing box 2, and one end of the smoke exhaust pipe 33 away from the crushing box 2 passes through the shell 1 and extends to the outside of the shell 1, a crushing mechanism is arranged inside the crushing box 2, the crushing mechanism comprises a rotating module and a crushing module, and the crushing mechanism is used to crush chemical raw materials;

[0024] The existing crushing device mainly relies on the crushing roller to squeeze to achieve the purpose of crushing raw materials. This method has a poor crushing effect. In order to solve the above problems, when this embodiment is used, the chemical raw materials are first added through the discharge port 32, and the chemical raw materials will enter the crushing box 2 along the feed pipe 31. At this time, the crushing mechanism is started, and the crushing mechanism hits the raw materials when it rotates, so that it can achieve the purpose of crushing. The smoke and dust generated during the crushing are accompanied by air and float out of the crushing box 2 through the exhaust pipe 33, avoiding the situation where there is too much smoke and dust in the crushing box 2, which causes trouble for later cleaning. This structure can effectively avoid pollution, solves the problem of direct crushing in the past causing smoke and dust to scatter and cause chronic effects on operators, and improves safety.

[0025] like Figure 3 As shown, the rotating module includes a fixing plate Ⅰ4, the fixing plate Ⅰ4 is fixedly connected to the outer side of the crushing box 2 near the upper position, the top of the fixing plate Ⅰ4 is fixedly connected to a motor Ⅰ5, the output end of the motor Ⅰ5 is fixedly connected to a gear Ⅰ6, one side of the gear Ⅰ6 is meshed with a gear ring 8, the inside of the gear ring 8 is meshed with a gear Ⅱ9, the side of the gear Ⅱ9 away from the gear ring 8 is meshed with a gear Ⅲ10, and the bottom of the gear ring 8 is rotatably connected to the top of the crushing box 2;

[0026] In order to realize the function of gear II9 and gear III10 rotating in opposite directions, the motor 5 drives the gear I6 to rotate during operation, and the gear I6 drives the gear ring 8 to rotate when rotating, and the gear ring 8 rotates and then drives the gear II9 to rotate. Since the gear II9 and the gear III10 are meshed, when the gear II9 rotates, it will drive the gear III to rotate in the opposite direction, thereby realizing the above-mentioned function of gear II9 and gear III10 rotating in opposite directions. It should be noted that there is no meshing relationship between the gear III10 and the gear ring 8. Therefore, the normal operation of the gear ring 8 will not be interfered with when the gear III10 rotates, and through this structural design, it can be realized that a single kinetic energy source can drive its operation, reducing the use of kinetic energy and reducing the working cost.

[0027] like Figure 4 and Figure 5As shown, the crushing module includes a rotating rod II 12 and a rotating rod I 11, and the rotating rod II 12 and the rotating rod I 11 are respectively fixed to the inside of the gear II 9 and the gear III 10, and the outer sides of the rotating rod I 11 and the rotating rod II 12 are rotatably connected with bearings 34, and a pair of outer sleeves of the bearings 34 are provided with limit sleeves 14, and the limit sleeves 14 are slidably connected to the bearings 34, and the outer side of the limit sleeve 14 is fixedly connected with a pair of fixed plates II 7, and the pair of fixed plates II 7 are connected to the housing away from the limit sleeve 14. 1 is fixedly connected to the inner wall of the housing 1, the tops of the rotating rods Ⅰ11 and Ⅱ12 are fixedly connected to the limit plate 15, the bottom of the limit plate 15 is in contact with the top of the limit sleeve 14, a pair of bearings 34 are rotatably connected to the opposite side with a lubrication shaft, the top of the lubrication shaft is fixedly connected to the top of the inner side of the housing 1, the rotating rods Ⅰ11 and Ⅱ12 are fixedly connected to the outside with multiple groups of crushing teeth 13, the crushing teeth 13 on the outside of the rotating rods Ⅰ11 and the crushing teeth 13 on the outside of the rotating rods Ⅱ12 are cross-arranged;

[0028] In order to realize the function of cross-crushing raw materials, when gear II9 and gear III10 rotate, they will drive rotating rod I11 and rotating rod II12 to rotate in opposite directions, and rotating rod I11 and rotating rod II12 will drive multiple groups of crushing teeth 13 to rotate synchronously. When the material falls under the action of gravity, multiple groups of crushing teeth 13 will rotate and hit the raw materials, and the lubrication shaft can ensure the stability of the bearing 34 during rotation. The lubrication shaft and the limit sleeve 14 will limit the two sides of the bearing 34 to ensure that the bearing 34 will not fall off during the rotation. The raw materials are subjected to the impact force and then diffused to the surroundings, avoiding the larger solid chemical raw materials from being unable to achieve the crushing function. Compared with single-group crushing and crushing rollers, cross-crushing is more comprehensive. At the same time, multiple groups of crushing teeth 13 can effectively avoid the leakage of raw materials when rotating at high speed, thereby improving the stability of the device.

[0029] like Figure 6 and Figure 7 As shown, a breaking component is arranged near the bottom end of the crushing box 2, and the breaking component is used to prevent the crushed chemical raw materials from agglomerating. The breaking component includes a rotating rod III16, one end of which is rotatably connected to the inner wall of the crushing box 2 near the lower position, and a motor II17 is arranged at one end of the rotating rod III16 away from the fixed block I3, and the output end of the motor II17 is fixedly connected to the rotating rod III16, and the end of the motor II17 away from the rotating rod III16 is fixedly connected to the fixed block II18, and the fixed block II18 is fixedly connected to the inner wall of the housing 1 at the side away from the motor II17;

[0030] Since there may be raw materials at the intersection during the cross-crushing process of the multiple groups of crushing teeth 13, the raw materials are piled up into blocks under the cross-action of the multiple groups 13. When the present embodiment is in use, when the raw materials fall onto the top of the rotating rod III16 after being crushed, the motor II17 is started. When the motor II17 is running, the rotating rod III16 is driven to rotate. When the raw materials piled up into blocks contact the rotating rotating rod III16, the rotating rod III16 will hit the raw materials, so that the raw materials piled up into blocks are hit by the rotating rod III16 and fly to the inner wall of the crushing box 2. Finally, the raw materials are concentratedly dropped through the discharge barrel 19 under the action of gravity. The structural design of the rotating rod III16 not only avoids the function of raw materials piling up into blocks, but also realizes the function of secondary crushing. One structure realizes dual functions, which greatly improves the versatility of the device.

[0031] Further, such as Figure 6 and Figure 7 As shown, a transmission belt 20 is sleeved on the outer side of the rotating rod III16, and a rotating shaft 21 is rotatably connected to the inner wall of the transmission belt 20 near the bottom end. One end of the rotating shaft 21 is rotatably connected to the inner wall of the shell 1, and a gear IV22 is fixedly connected to the outer side of the rotating shaft 21. The gear IV22 is a half gear, and a rack 23 is meshed on one side of the gear IV22. A fixed block III27 is fixedly connected to one side of the rack 23, and a sieve plate 28 is fixedly connected to the fixed block III27 away from the side of the rack 23. The top of the rack 23 is fixedly connected to A fixing plate III 24, a compression spring 25 is fixedly connected to the top of the fixing plate III 24, a fixing plate IV 26 is fixedly connected to the end of the compression spring 25 away from the fixing plate III 24, one end of the fixing plate IV 26 is fixedly connected to the outside of the crushing box 2, and the end of the fixing plate IV 26 away from the crushing box 2 is fixedly connected to the inner wall of the housing 1, and a guide rod is fixedly connected to the bottom end of the fixing plate IV 26, and the guide rod is designed as a "triangular pyramid", and the end of the guide rod away from the fixing plate IV 26 passes through the fixing plate III 24 and is slidably connected to the inside of the rack 23;

[0032] In order to realize the function of screening and crushing raw materials, the existing screen plate 28 is prone to blockage. In order to solve the above problem, the rotation of the rotating rod III 16 drives the rotating shaft 21 to rotate through the transmission belt 20, and the rotation of the rotating shaft 21 drives the gear IV 22 to rotate. The rotation of the gear IV 22 drives the rack 23 to move upward. The movement of the rack 23 will drive the screen plate 28 to move through the fixed block III 27. During the movement, the rack 23 squeezes the compression spring 25 through the fixed plate III 24, causing the compression spring 25 to deform and generate elastic potential energy. As the gear IV 22 continues to rotate, when the notch of the gear IV 22 is at the same horizontal plane as the rack 23, the meshing of the gear IV 22 and the rack 23 ends, and the compression spring 25 is deformed and generates elastic potential energy. 25 and then the force ends, the elastic potential energy is released instantly, and the rack 23 is pushed downward to reset instantly through the fixed plate III 24. The rack 23 is reset and then the sieve plate 28 is driven to reset through the fixed block III 27. At this time, the sieve plate 28 realizes reciprocating movement. When the raw materials fall into the center of the sieve plate 28, the raw materials are prevented from blocking the sieve plate 28, resulting in a decrease in the raw material screening rate and an increase in the working time. It should be noted that the guide rod is designed in a "triangular" shape, which allows the triangular corners of the guide rod to move inside the rack 23, ensuring that the rack 23 will not rotate when it moves at a high altitude, thereby ensuring the normal operation of the device. Through this design, the crushed and dispersed particles can be further screened and loosened, thereby obtaining finer chemical raw materials.

[0033] Further, such as Figure 4 and Figure 6 As shown, the bottom of the sieve plate 28 abuts against a support block 29, and the support block 29 is fixedly connected to the bottom end of the housing 1. A collection box 30 is arranged inside the support block 29, and one end of the collection box 30 away from the support block 29 penetrates the housing 1 and is slidably connected to the bottom end of the housing 1.

[0034] In order to realize the function of collecting processed raw materials, when this embodiment is in use, the raw materials passing through the screen plate 28 will all fall into the collection box 30. When collected to a certain extent, the processed raw materials can be taken out by pulling the collection box 30, which improves the convenience of the device. The support block 29 can ensure that when the screen plate 28 vibrates up and down, the rack 23 will not be disengaged from the meshing position of the gear IV 22, thereby avoiding failure of the device.

[0035] Working principle: the existing crushing device mainly relies on the crushing roller to squeeze to achieve the purpose of crushing raw materials. This method has a poor crushing effect. In order to solve the above problems, when this embodiment is used, the chemical raw materials are first added through the discharge port 32, and the chemical raw materials will enter the crushing box 2 along the feed pipe 31. At this time, the crushing mechanism is started, and the crushing mechanism hits the raw materials when it rotates, so that it can achieve the purpose of crushing. The smoke and dust generated during the crushing are accompanied by air and float out of the crushing box 2 through the exhaust pipe 33, avoiding the situation where there is too much smoke and dust in the crushing box 2, which causes troubles in the later cleaning. This structure can be used to avoid pollution, which solves the problem of direct The problem of the chronic impact of smoke and dust scattered during pulverization on operators is solved, and the safety is improved. In order to realize the function of gear II 9 and gear III 10 rotating in opposite directions, the motor 5 drives the gear I 6 to rotate during operation, and the gear I 6 drives the gear ring 8 to rotate when rotating, and the gear ring 8 rotates and then drives the gear II 9 to rotate. Since the gear II 9 and the gear III 10 are meshed, when the gear II 9 rotates, it will drive the gear III to rotate in the opposite direction, thereby realizing the above-mentioned function of gear II 9 and gear III 10 rotating in opposite directions. It should be noted that there is no meshing relationship between the gear III 10 and the gear ring 8. Therefore, when the gear III 10 rotates, it will not interfere with the gear ring 8. Normal operation, and through this structural design, a single kinetic energy source can be used to drive its operation, reducing the use of kinetic energy and reducing working costs. In order to realize the function of cross-crushing raw materials, when gears II 9 and III 10 rotate, they will drive the rotating rods I 11 and II 12 to rotate in opposite directions, and the rotating rods I 11 and II 12 will drive the multiple groups of crushing teeth 13 to rotate synchronously. When the material falls under the action of gravity, the multiple groups of crushing teeth 13 will rotate and hit the raw materials, and the lubricating shaft can ensure the stability of the bearing 34 during rotation. The lubricating shaft and the limit spring 14 will limit the two sides of the bearing 34 to ensure that the bearing 34 is stable during rotation. The raw materials will not fall off during the movement, and the raw materials will be impacted and spread around, which avoids the inability to crush larger solid chemical raw materials. Compared with a single group of crushing and crushing rollers, the cross crushing is more comprehensive. At the same time, the multiple groups of crushing teeth 13 can effectively avoid the leakage of raw materials when rotating at high speed, and improve the stability of the device. Since there may be raw materials at the intersection of the multiple groups of crushing teeth 13 during the cross crushing process, the raw materials are piled up into blocks under the cross action of the multiple groups 13. When the raw materials fall above the rotating rod III 16 after being crushed, the 17 is started.When 17 is running, it drives the rotating rod III 16 to rotate. When the raw materials accumulated into blocks contact the rotating rotating rod III 16, 16 will hit the raw materials, so that the raw materials accumulated into blocks are hit by the rotating rod III 16 and fly to the inner wall of the crushing box 2. Finally, the raw materials are concentrated and fall through the discharge barrel 19 under the action of gravity. The structural design of the rotating rod III 16 not only avoids the function of raw materials piling up into blocks, but also realizes the function of secondary crushing. One structure realizes dual functions, which greatly improves the versatility of the device. In order to realize the function of screening the crushed raw materials, the existing screen plate 28 is prone to In order to solve the above problem, the rotation of the rotating rod III 16 drives the rotating shaft 21 to rotate through the transmission belt 20, and the rotation of the rotating shaft 21 drives the gear IV 22 to rotate. The rotation of the gear IV 22 drives the rack 23 to move upward. The movement of the rack 23 drives the sieve plate 28 to move through the fixed block III 27. During the movement, the rack 23 squeezes the compression spring 25 through the fixed plate III 24, causing the compression spring 25 to deform and generate elastic potential energy. As the gear IV 22 continues to rotate, when the notch of the gear IV 22 is at the same horizontal plane as the rack 23, the gear IV 2 2 ends the meshing with the rack 23, the compression spring 25 ends the force, the elastic potential energy is released instantly, and the rack 23 is pushed downward instantly through the fixing plate III 24, the rack 23 is reset and then the sieve plate 28 is driven to reset through the fixing block III 27, at this time the sieve plate 28 realizes reciprocating movement, when the raw materials fall into the center of the sieve plate 28, the raw materials are prevented from blocking the sieve plate 28, resulting in a decrease in the raw material screening rate and an increase in the working time. It should be noted that the guide rod is designed in a "triangular" shape, which allows the triangular corners of the guide rod to move inside the rack 23, ensuring that the rack 23 does not rotate when it moves at a high altitude. This ensures the normal operation of the device. Through this design, the crushed and scattered particles can be further screened and loosened to obtain finer chemical raw materials. In order to realize the function of collecting and processing raw materials, when this embodiment is used, the raw materials passing through the sieve plate 28 will fall into the collection box 30. When collected to a certain extent, the processed raw materials can be taken out by pulling the collection box 30, which improves the convenience of the device. The support block 29 can ensure that when the sieve plate 28 vibrates up and down, the rack 23 will not be separated from the meshing position of the gear IV 22, thereby avoiding the failure of the device.
