Abstract
Description
Technical Field
[0001] This utility model relates to the field of crushing device technology, and specifically discloses a raw material crushing device. Background Technology
[0002] In modern industrial production, the crushing of medium-hard or low-hardness lumpy raw materials into granular materials is a crucial step. These granular materials are widely used in various fields, including chemical, food, pharmaceutical, and building materials industries. For example, in the chemical industry, granular materials can be used as catalysts and adsorbents; in the food industry, they can be used as seasonings and additives; in the pharmaceutical industry, they can be used as drug components and excipients; and in the building materials industry, they can be used as aggregates in concrete and mortar.
[0003] For example, the utility model with authorization announcement number CN220111175U discloses a raw material crushing device, including: an outer casing with a feeding port fixed at the top and a discharge port at the lower end of one side of the outer casing; a crushing roller disposed at the upper part of the outer casing; a carrying box disposed at the lower part of the outer casing; and a weighing and feeding assembly disposed at the lower end of the carrying box inside the outer casing. This utility model provides a raw material crushing device that, through the coordinated design of multiple structures, can meet the basic requirements of crushing. After the raw material is crushed by the crushing roller, it can be carried by the carrying box. The weighing and feeding assembly can weigh the crushed raw material carried by the carrying box. When the weight reaches a set value, it can push the carrying box, causing it to tilt, thereby discharging the crushed raw material carried by the carrying box from the discharge port. Thus, the device can achieve both crushing and quantitative output of materials. Currently, after large-volume raw materials are crushed by roller crushers, they are formed into blocks of different sizes. For medium-hardness or low-hardness materials, in order to further crush them for use, they need to be changed from blocks to granules. In most cases, hammer crushing devices are used. However, the hammer crushing method can easily cause the piled-up blocks of raw materials waiting to be crushed to have a large size difference between the upper and lower layers of crushed particles. At the same time, some raw materials generate dust during crushing, and the generated dust needs to be treated to ensure the stability and safety of the crushing process. Utility Model Content
[0004] In view of this, the purpose of this utility model is to provide a raw material crushing device to solve the problem of being able to stably crush medium or low hardness block raw materials into granular materials, while also handling the dust raised during crushing.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a raw material crushing device, including a supporting mechanism, a crushing mechanism is arranged above the supporting mechanism, and dust collection mechanisms are also distributed on both sides of the supporting mechanism;
[0006] The supporting mechanism includes a base, a column, a mounting sleeve, and a storage cylinder;
[0007] The crushing mechanism includes a top plate, a hydraulic cylinder, and a crushing head;
[0008] The vacuuming mechanism includes an air pump and a vacuum hood.
[0009] Furthermore, columns are distributed along both sides above the base, and mounting sleeves are wrapped around the middle of the columns. A storage cylinder is provided between the mounting sleeves distributed along both sides, and the outer wall of the storage cylinder is fixedly connected to the corresponding mounting sleeve through a bracket.
[0010] Furthermore, a cylinder is provided above the base, and the cylinders are symmetrically distributed along both sides of the base. A piston rod for extension and retraction is provided inside the cylinder. The ends of the piston rods distributed along both sides are provided with the same sealing plate. The upper end of the sealing plate covers the bottom of the storage cylinder, and a baffle is provided at the upper end of the storage cylinder.
[0011] Furthermore, the upper ends of the columns distributed along both sides are provided with the same top plate, and a hydraulic cylinder is installed through the inside of the top plate. The hydraulic cylinder is distributed along both sides of the top plate, and a second piston rod for extension and retraction is installed inside the hydraulic cylinder, and a lifting plate is provided at the end of the second piston rod.
[0012] Furthermore, a bearing is installed through the center of the lifting plate, and a shaft is installed through the bearing. The shaft is interference-fitted with the inner ring wall of the bearing. A motor is installed at the upper end of the shaft, and a drive shaft is installed inside the motor. The end of the shaft is fixedly connected to the shaft by a coupling.
[0013] Furthermore, a crushing head is provided below the lifting plate. The crushing head has a conical structure, with several crushing protrusions distributed on the conical surface and several crushing protrusions distributed on the bottom.
[0014] Furthermore, an air pump is installed above the base, and the air pumps are symmetrically distributed on both sides of the storage cylinder. A dust suction pipe is installed on the air inlet flange of the air pump. A dust suction hood is installed at the end of the dust suction pipe away from the air pump. The upper and lower ends of the dust suction hood are fixedly installed on the surface of the support and the column, respectively. A dust suction interface is fixedly installed through the end of the dust suction hood near the dust suction pipe. The connection between the dust suction interface and the dust suction pipe is connected by a flange. The interior of the dust suction hood has an opening and a grid plate is embedded therein.
[0015] Furthermore, a dust collection cylinder is installed on the air outlet flange of the air pump, and an isolation net is provided on the inner wall of the dust collection cylinder. The edge of the isolation net is bonded and fixed to the inner wall of the dust collection cylinder with resin adhesive, and the isolation net is made of non-woven fabric.
[0016] The working principle and beneficial effects of this solution are as follows: 1. This solution uses a conical crushing head and ceramic particles on the inner wall of the storage cylinder to work together through the crushing mechanism. The crushing protrusions 1 and 2 on the surface of the crushing head come into contact with the blocky raw material at multiple angles during the rotation process, which not only enhances the crushing force, but also avoids the problems of material accumulation or local over-crushing. The conical inner cavity design of the storage cylinder allows the material to move downward naturally under the action of gravity. Combined with the upper and lower hydraulic drive of the crushing head, a dynamic crushing space is formed to ensure that the material is repeatedly ground during the flow process. In addition, the gap design between the crushing head and the inner wall of the storage cylinder not only prevents wear caused by direct metal friction, but also ensures the uniformity of the granular material.
[0017] 2. As described in 1, the air pump directly sucks the dust generated during crushing into the dust collection cylinder through the dust suction hood and dust suction pipe. The grid plate inside the dust suction hood effectively intercepts large particles of impurities and prevents pipe blockage. The non-woven fabric isolation net inside the dust collection cylinder further filters fine dust, ensuring that the exhaust airflow is clean. At the same time, the dust is collected in a concentrated manner for subsequent processing or recycling.

[0028] The following detailed description illustrates the specific implementation methods:
[0029] Example
[0030] like Figures 1 to 6 As shown, a raw material crushing device is disclosed, including a supporting mechanism 1, a crushing mechanism 2 is arranged above the supporting mechanism 1, and dust collection mechanisms 3 are also distributed on both sides of the supporting mechanism 1.
[0031] The supporting mechanism 1 includes a base 10, a column 11, a mounting sleeve 12, and a storage cylinder 13;
[0032] The crushing mechanism 2 includes a top plate 20, a hydraulic cylinder 21, and a crushing head 203;
[0033] The vacuuming mechanism 3 includes an air pump 30 and a vacuum hood 32.
[0034] The base 10 has columns 11 arranged on both sides above it. The lower end of the columns 11 is fixed to the surface of the base 10 with screws. The middle part of the columns 11 is covered with a mounting sleeve 12. The connection between the mounting sleeve 12 and the column 11 is fixed with screws. The storage cylinder 13 is arranged between the mounting sleeves 12 arranged on both sides. The outer wall of the storage cylinder 13 is fixedly connected to the corresponding mounting sleeve 12 through a bracket. The mounting sleeve 12 can be fixed based on the columns 11 and stably place the storage cylinder 13. The inside of the storage cylinder 13 is provided with a conical crushing and processing inner cavity. The upper and lower ends of the inner cavity are open. The inner wall of the inner cavity is covered with dense ceramic particles, which can be used to assist in grinding and processing.
[0035] A cylinder 14 is installed above the base 10. The lower end of the cylinder 14 is fixedly installed to the surface of the base 10 by screws. The cylinders 14 are symmetrically distributed on both sides of the base 10. The cylinder 14 is equipped with a piston rod for extension and retraction. The piston rods distributed on both sides are connected to the same sealing plate 15. The sealing plate 15 is fixed to the connection position of any piston rod by screws. The upper end of the sealing plate 15 covers the bottom of the storage cylinder 13. The sealing plate 15 can be moved up and down by extending and retracting the piston rod of the cylinder 14. When the sealing plate 15 is in contact with the bottom of the storage cylinder 13, it can ensure the stability of the crushed lumpy raw material stored in the storage cylinder 13. After crushing, the sealing plate 15 can be moved downward so that the lumpy raw material can be directly discharged after being crushed into granular material. A baffle 16 is installed at the upper end of the storage cylinder 13. The lower end of the baffle 16 is fixedly assembled to the end face of the storage cylinder 13. The baffle 16 can play an auxiliary anti-splashing role when crushing lumpy raw material.
[0036] The top of the columns 11 distributed on both sides is provided with the same top plate 20. The connection between the top plate 20 and the columns 11 is fixed with screws. A hydraulic cylinder 21 is installed through the top plate 20. The connection between the hydraulic cylinder 21 and the top plate 20 is fixed with screws. The hydraulic cylinder 21 is distributed on both sides of the top plate 20. The hydraulic cylinder 21 is provided with a piston rod 2 for extension and retraction. The end of the piston rod 2 is provided with a lifting plate 22. The lifting plate 22 is fixed to the end of any piston rod 2 with screws. When it is necessary to move the crushing head 203 for crushing, the piston rod 2 of the hydraulic cylinder 21 extends and retracts, so that the crushing head 203 can move up and down, thereby gradually entering the storage cylinder 13 and contacting the block raw material, so as to crush the block raw material.
[0037] A bearing 201 is installed through the center of the lifting plate 22. The bearing 201 is fixed to the lifting plate 22 by welding. A shaft 202 is installed through the inside of the bearing 201. The shaft 202 is interference-fitted with the inner ring wall of the bearing 201. A motor 206 is installed at the upper end of the shaft 202. The outer ring wall of the motor 206 is fixedly installed to the surface of the lifting plate 22 by a bracket. A drive shaft is installed inside the motor 206. The end of the shaft is fixedly connected to the shaft 202 by a coupling. When the crushing head 203 needs to be driven, the power supply to the motor 206 is turned on, so that the motor 206 can drive the shaft to rotate. This causes the shaft to drive the shaft 202 to rotate, thereby allowing the crushing head 203 to rotate stably.
[0038] A crushing head 203 is located below the lifting plate 22. The upper end of the crushing head 203 is fixed to the end of the shaft 202 by screws. The crushing head 203 has a conical structure, and its conical shape fits the inside of the storage cylinder 13. When the surface of the crushing head 203 enters the inside of the storage cylinder 13, a gap is formed between it and the inner wall of the storage cylinder 13. This ensures that the crushing process does not involve complete contact, avoiding wear between the crushing components. It also ensures a stable process for crushing lumpy raw materials into granular materials. The conical surface is provided with several crushing protrusions 204. Any one of the crushing protrusions 204 is welded and fixed to the surface of the crushing head 203. The bottom of the crushing head 203 is provided with several crushing protrusions 205. Any one of the crushing protrusions 205 is welded and fixed to the bottom of the crushing head 203. The crushing head 203, crushing protrusions 204 and crushing protrusions 205 are all made of stainless steel. When they come into contact with blocky materials, they can further crush the blocky raw materials into granular materials in conjunction with the ceramic particles distributed on the inner wall of the storage cylinder 13.
[0039] An air pump 30 is installed above the base 10. The air pumps 30 are symmetrically distributed on both sides of the storage cylinder 13. The lower end of the air pump 30 is fixedly mounted to the surface of the base 10 via a bracket. A suction pipe 31 is installed on the air inlet flange of the air pump 30. A suction hood 32 is installed at the end of the suction pipe 31 away from the air pump 30. The upper and lower ends of the suction hood 32 are fixedly mounted to the surface of the column 11 via brackets. A suction port 33 is fixedly installed through the end of the suction hood 32 near the suction pipe 31. The connection between the suction port 33 and the suction pipe 31 is open. The dust collection hood 32 is fitted with an opening through a flange and a grid plate 34 is embedded inside. The edge of the grid plate 34 is fixed to the inner wall of the dust collection hood 32 with screws. When dust collection is required during the crushing process, the power supply of the air pump 30 is turned on, so that the air pump 30 can perform a suction effect. The air pump 30 can suck the dust into the dust collection pipe 31. Thus, the dust is further transported by the air pump 30. The grid plate 34 can block large lint and dust carried by the airflow during the dust collection process, preventing them from clogging the interior of the air pump 30.
[0040] The air pump 30 has a dust collection cylinder 3001 installed on its outlet flange. An isolation net 3002 is installed on the inner wall of the dust collection cylinder 3001. The edge of the isolation net 3002 is bonded to the inner wall of the dust collection cylinder 3001 with resin adhesive. The isolation net 3002 is made of non-woven fabric. When the air pump 30 is pumping air, the isolation net 3002 can ensure that the airflow can pass through the isolation net 3002 normally. At the same time, it can isolate the dust inside the dust collection cylinder 3001 for collection.
[0041] In practice
[0042] The supporting mechanism 1 of this scheme supports the overall structure through the base 10. The lower end of the column 11 is fixed to the base 10 with screws, and the middle part is wrapped with the mounting sleeve 12. The mounting sleeve 12 is fixed to the column 11 with screws and provides stable support for the storage cylinder 13. The crushing mechanism 2 drives the piston rod 2 to extend and retract through the hydraulic cylinder 21, which drives the lifting plate 22 to move up and down, so that the crushing head 203 gradually enters the storage cylinder 13. The crushing head 203 has a conical structure, and its surface is distributed with crushing protrusion 1 204 and crushing protrusion 205, both of which are made of stainless steel. When the motor 206 starts, the rotating shaft drives... The shaft 202 rotates, causing the crushing head 203 to rotate at high speed inside the storage cylinder 13. The inner wall of the storage cylinder 13 is covered with dense ceramic particles, which cooperate with the crushing protrusions of the crushing head 203 to squeeze, shear and grind the blocky raw materials. A gap is left between the crushing head 203 and the inner wall of the storage cylinder 13 to avoid direct contact and wear, while ensuring that the raw materials are fully crushed into granular materials. The sealing plate 15 is controlled to rise and fall by the piston rod of the cylinder 14. Initially, it seals the bottom of the storage cylinder 13. After crushing, it moves down to discharge the granular materials. The enclosure 16 prevents the raw materials from splashing during the crushing process and ensures a stable processing environment.
[0043] The dust collection mechanism 3 generates negative pressure through the air pump 30, which draws the dust generated during the crushing process into the dust collection pipe 31. The dust collection hood 32 is fixed on the column 11 and has a grid plate 34 inside, which can block large lint or debris from entering the dust collection pipe 31 and prevent the air pump 30 from getting clogged. After the dust enters the dust collection pipe 31 through the dust collection interface 33, it is transported to the dust collection cylinder 3001. The dust collection cylinder 3001 is equipped with a non-woven fabric isolation net 3002, which allows airflow to pass through while trapping the dust inside the dust collection cylinder 3001. The isolation net 3002 is fixed with resin glue to ensure its stability.
[0044] The above description is merely an embodiment of this utility model, and common knowledge such as specific structures and characteristics in the solution is not described in detail here. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model, and these should also be considered within the protection scope of this utility model. These modifications and improvements will not affect the effectiveness of the implementation of this utility model or its practicality.
