Description

Technical Field

[0001] This invention belongs to the field of grinding equipment technology, and particularly relates to a raw material grinding equipment for high-efficiency chemical processing. Background Technology

[0002] Chemical raw materials refer to various chemicals and substances used in chemical industrial production, including organic chemicals, inorganic chemicals, polymer materials, synthetic fibers, fine chemicals, pesticides, pharmaceuticals, dyes, pigments, coatings, plastics, rubber, etc. These chemicals and substances are widely used in various fields, such as industry, agriculture, medicine, construction, and food. During the use of chemical raw materials, they need to be processed, typically using chemical raw material grinding equipment to grind them.

[0003] To address this, Chinese Patent No. CN217140521U discloses a chemical raw material grinding device, which consists of a housing, a blower plate, and a controller. The housing contains a first grinding roller, and a second grinding roller is located at the lower end of the first grinding roller. Rotating shafts are located inside the first and second grinding rollers. A filter plate is located at the lower end of the second grinding roller. A feed inlet is located at the upper end of the housing. A first motor housing is located on the right side of the housing, and a second motor housing is located on the left side of the housing. A blower plate is located at the rear of the housing, and a controller is located at the front of the housing. A fan is located on the outer side of the blower plate, and a blower pipe is located on the blower plate. The blower pipe extends into the housing and blows air into the housing, which can accelerate the movement of the ground chemical raw materials and prevent the ground chemical raw materials from sticking to the first and second grinding rollers.

[0004] However, the aforementioned device only blows the material adhering to the grinding roller to fall off. During the grinding process, the material adhering to the roller may clump together into lumps or cakes, which are difficult to remove completely by wind alone. It cannot scrape the material off completely, resulting in poor cleaning effect, which in turn affects the grinding quality and grinding efficiency. Summary of the Invention

[0005] To address the problems existing in the prior art, this invention provides a raw material grinding device for high-efficiency chemical processing. It features a single motor that, in conjunction with a transmission belt and a toothed disc, synchronously drives the crushing components and dual grinding rollers, simplifying the structure and saving costs. The raw materials are first refined by the crushing blades and then thoroughly ground by the opposing grinding rollers, improving grinding efficiency. Furthermore, the scraper adheres closely to the grinding rollers, thoroughly scraping away any clumps of raw material and preventing residue from affecting grinding quality. This effectively improves grinding efficiency and solves the problem in the prior art where raw materials adhering during grinding may clump or cake, making it difficult to completely remove them by wind alone, resulting in poor cleaning and consequently affecting grinding quality and efficiency.

[0006] This invention is implemented as follows: a raw material grinding device for high-efficiency chemical processing includes a grinding box. The grinding box contains, from top to bottom, a crushing chamber, a grinding chamber, and a discharge port. A feed hopper is fixedly installed on the top of the grinding box. A crushing component for primary crushing of the raw material is rotatably mounted on the crushing chamber. The crushing component includes a rotating rod. A grinding component for grinding the raw material is rotatably mounted on the grinding box. The grinding component includes two grinding rods, each with a grinding roller fixedly fitted onto it. One of the grinding rods is connected to the outer end of the rotating rod via a transmission belt. Scraping components are correspondingly provided at the bottom of both grinding rollers. The scraping components include scraper plates. When cleaning the grinding rollers, the scraper plates can move upwards and come into contact with the outer surface of the grinding rollers.

[0007] In a preferred embodiment of the present invention, a motor is fixedly connected to the outer wall of the grinding box, the output end of the motor is fixedly connected to the outer end of the rotating rod, a drive wheel is sleeved and fixed to the outer end of the rotating rod, and a driven wheel is sleeved and fixed to the outer end of the grinding rod. The driven wheel and the drive wheel are connected by a transmission belt.

[0008] With this setup, only a single motor is needed to synchronously drive the crushing and grinding parts, eliminating the need for multiple additional drive units. This simplifies the equipment structure, reduces manufacturing costs, and ensures the transmission coordination between the rotating rod and the grinding rod.

[0009] As a preferred embodiment of the present invention, uniformly distributed crushing blades are sleeved and fixed on the rotating rod, the crushing blades are located in the crushing chamber, and the bottom of the crushing chamber is provided with uniformly distributed feeding channels.

[0010] With this setup, when the rotating rod drives the crushing blades to rotate at high speed, it can perform initial crushing of large-volume chemical raw materials fed into the crushing chamber, refining large particles. The crushed raw materials can fall evenly into the grinding chamber through the feeding channel, avoiding the accumulation of raw materials in the grinding chamber and causing uneven grinding. This lays the foundation for uniform feeding in subsequent grinding processes and improves the overall grinding efficiency.

[0011] As a preferred embodiment of the present invention, both of the grinding rods are fitted with toothed discs at their outer ends, and the toothed discs are meshed together.

[0012] With this setup, when a single motor drives one of the grinding rods to rotate, the meshing transmission of the gear disc can drive the other grinding rod to rotate synchronously in the opposite direction, so that the grinding rollers on the two grinding rods form a counter-grinding action, which enhances the squeezing and grinding effect on the raw materials, ensures the grinding fineness of the chemical raw materials, and meets the process requirements.

[0013] As a preferred embodiment of the present invention, both ends of the scraper are fixedly connected to guide slide rods, the ends of the guide slide rods slide through to the outside of both sides of the grinding box and a lifting support plate is fixed between the ends, and guide slide holes are provided on both sides of the grinding box, and the guide slide rods slide up and down along the guide slide holes.

[0014] With this setting, the cooperation between the guide slide rod and the guide slide hole provides stable guidance for the lifting and lowering of the scraper, preventing the scraper from deviating when it moves. The lifting support plate can drive the guide slide rods at both ends to move synchronously, ensuring that the lifting height of both ends of the scraper is consistent, so that the scraper can evenly fit the outer surface of the grinding roller, ensuring uniform scraping effect and preventing local residual agglomerated raw materials.

[0015] As a preferred embodiment of the present invention, a fixing plate is fixedly connected to both outer sides of the grinding box, and a screw and a support rod are respectively provided on the two fixing plates, with the lifting support plate sleeved between the screw and the support rod.

[0016] With this setup, the fixed plate provides stable support for the screw and the support rod, and the double support structure formed by the screw and the support rod enhances the installation stability of the lifting support plate. At the same time, when the lifting support plate moves between the screw and the support rod, it can avoid tilting and shaking, further ensuring the stability of the scraper plate during the lifting process and providing structural protection for precise scraping.

[0017] In a preferred embodiment of the present invention, the screw and the fixed plate are connected by a bearing, the support rod and the fixed plate are fixedly connected, one end of the lifting support plate is threaded onto the screw, and the other end of the lifting support plate is slidably sleeved onto the support rod.

[0018] With this setup, when the screw is rotated, the threaded transmission drives the lifting support plate to move along the screw axis, allowing it to slide smoothly up and down. This enables precise control of the scraper's lifting height, more stably controlling the adhesion between the scraper and the grinding roller. Combined with the self-rotation of the grinding roller, this thoroughly scrapes away and cleans the adhering material on the surface of the grinding roller, ensuring that the clumps of material are completely removed. This effectively enhances the cleaning force and effect on the grinding roller, ensuring grinding precision and quality, and thus improving grinding efficiency.

[0019] As a preferred embodiment of the present invention, a discharge filter plate is fixedly connected to the top of the discharge port by bolts.

[0020] With this setup, the discharge filter plate can screen the ground raw materials, allowing those that meet the fineness requirements to be discharged through the outlet, ensuring the final output quality. The bolt fixing method facilitates the periodic disassembly of the filter plate for cleaning or replacement, adapting to the grinding fineness requirements of different chemical raw materials and improving the equipment's versatility and ease of maintenance.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: By using a single motor in conjunction with a transmission belt and a toothed disc to synchronously drive the crushing parts and double grinding rollers, the structure is simplified and costs are saved. The raw materials are first refined by the crushing blades and then fully ground by the opposing grinding rollers, improving grinding efficiency. Moreover, the scraper can be precisely adjusted in height by the screw, and the scraper plate is in contact with the grinding rollers to thoroughly scrape off the agglomerated raw materials, avoiding residues that affect the grinding quality. The whole process realizes the integration of raw material crushing, grinding, cleaning and screening, improving grinding efficiency and precision, adapting to the needs of different chemical raw materials, reducing equipment costs and maintenance difficulty, and effectively improving grinding efficiency.

[0029] To further understand the invention's content, features, and effects, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0030] The structure of the present invention will now be described in detail with reference to the accompanying drawings.

[0031] refer to Figures 1 to 6As shown in the figure, an embodiment of the present invention provides a raw material grinding device for high-efficiency chemical processing, including a grinding box 1. The grinding box 1 has a crushing chamber 102, a grinding chamber 103 and a discharge port 104 arranged sequentially from top to bottom inside. A feed hopper 101 is fixedly installed on the top of the grinding box 1. A crushing component for primary crushing of raw materials is rotatably installed on the crushing chamber 102. The crushing component includes a rotating rod 2. A grinding component for grinding raw materials is rotatably installed on the grinding box 1. The grinding component includes two grinding rods 3. A grinding roller 301 is sleeved and fixed on each of the grinding rods 3. The outer end of one of the grinding rods 3 and the rotating rod 2 are connected by a transmission belt 204. A scraper is provided at the bottom of each of the two grinding rollers 301. The scraper includes a scraper plate 6. When cleaning the grinding rollers 301, the scraper plate 6 can move upward and fit against the outer surface of the grinding rollers 301.

[0032] Specifically, a motor 202 is fixedly connected to the outer wall of the grinding box 1. The output end of the motor 202 is fixedly connected to the outer end of the rotating rod 2. A drive wheel 203 is sleeved and fixed to the outer end of the rotating rod 2. A driven wheel 303 is sleeved and fixed to the outer end of the grinding rod 3. The driven wheel 303 and the drive wheel 203 are connected by a transmission belt 204.

[0033] Using the above solution, only a single motor 202 is needed to drive the crushed parts and grinding parts to operate synchronously, without the need for multiple additional drive devices. This simplifies the equipment structure, reduces manufacturing costs, and ensures the transmission coordination between the rotating rod 2 and the grinding rod 3.

[0034] Specifically, the rotating rod 2 is fitted with uniformly distributed crushing blades 201, which are located in the crushing chamber 102. The bottom of the crushing chamber 102 is provided with uniformly distributed feeding channels 4.

[0035] Using the above scheme, when the rotating rod 2 drives the crushing blade 201 to rotate at high speed, it can perform initial crushing on the large-volume chemical raw materials fed into the crushing chamber 102, and refine the large particles of raw materials; the crushed raw materials can fall evenly into the grinding chamber 103 through the feeding channel 4, avoiding the accumulation of raw materials in the grinding chamber 103 and causing uneven grinding, laying a foundation for uniform feeding in subsequent grinding processes, and improving the overall grinding efficiency.

[0036] Specifically, both grinding rods 3 have a toothed disc 302 fixedly fitted to their outer ends, and the toothed discs 302 are meshed together.

[0037] Using the above scheme, when a single motor 202 drives one of the grinding rods 3 to rotate, the other grinding rod 3 can be driven to rotate synchronously in the opposite direction through the meshing transmission of the toothed disc 302, so that the grinding rollers 301 on the two grinding rods 3 form a counter-grinding action, which enhances the squeezing and grinding effect on the raw materials, ensures the grinding fineness of the chemical raw materials, and meets the process requirements.

[0038] Specifically, both ends of the scraper 6 are fixedly connected to guide slide rods 601. The ends of the guide slide rods 601 slide through to the outside of both sides of the grinding box 1 and the ends are fixed with lifting support plates 602. Guide slide holes 8 are opened on both sides of the grinding box 1, and the guide slide rods 601 slide up and down along the guide slide holes 8.

[0039] Using the above scheme, the cooperation between the guide slide rod 601 and the guide slide hole 8 provides stable guidance for the lifting and lowering of the scraper plate 6, avoiding deviation when the scraper plate 6 moves. The lifting support plate 602 can synchronously drive the guide slide rods 601 at both ends to move, ensuring that the lifting height of the scraper plate 6 at both ends is consistent, so that the scraper plate 6 can evenly fit the outer surface of the grinding roller 301, ensuring uniform scraping effect and preventing local residual agglomerated raw materials.

[0040] Specifically, the grinding box 1 is fixedly connected to two outer sides with fixing plates 7, and the two fixing plates 7 are respectively provided with screws 603 and support rods 604. The lifting support plate 602 is sleeved between the screws 603 and the support rods 604.

[0041] Using the above scheme, the fixing plate 7 provides stable support for the screw 603 and the support rod 604. The double support structure formed by the screw 603 and the support rod 604 can enhance the installation stability of the lifting support plate 602. At the same time, when the lifting support plate 602 moves between the screw 603 and the support rod 604, it can avoid tilting and shaking, further ensuring the stability of the scraper plate 6 during the lifting process, and providing structural guarantee for accurate scraping.

[0042] Specifically, the screw 603 is connected to the fixed plate 7 via a bearing, the support rod 604 is fixedly connected to the fixed plate 7, one end of the lifting support plate 602 is threaded onto the screw 603, and the other end of the lifting support plate 602 is slidably sleeved onto the support rod 604.

[0043] By adopting the above scheme, when the screw 603 is rotated, the screw drive can drive the lifting support plate 602 to move along the axial direction of the screw 603, so that it can only slide smoothly up and down, thereby achieving precise control of the lifting height of the scraper 6. This allows for more stable control of the adhesion force between the scraper 6 and the grinding roller 301. Combined with the self-rotation of the grinding roller, the adhering material on the surface of the grinding roller is thoroughly scraped and cleaned from all directions, ensuring that the clumps of raw materials are completely scraped off. This effectively enhances the cleaning force and effect on the grinding roller 301, ensuring grinding precision and quality, and thus improving grinding efficiency.

[0044] Specifically, the top of the discharge port 104 is fixedly connected to the discharge filter plate 5 by bolts.

[0045] Using the above scheme, the discharge filter plate 5 can screen the ground raw materials, allowing the raw materials that meet the fineness requirements to be discharged through the discharge port 104, ensuring the final output quality; the bolt fixing method facilitates the periodic disassembly of the filter plate for cleaning or replacement, adapts to the grinding fineness requirements of different chemical raw materials, and improves the versatility and maintenance convenience of the equipment.

[0046] Working principle of the invention:

[0047] When in use, after the motor 202 starts, it drives the rotating rod 2 of the crushing part to rotate. The rotating rod 2 drives one of the grinding rods 3 to rotate through the driving wheel 203, the transmission belt 204 and the driven wheel 303. The two grinding rods 3 achieve synchronous reverse rotation with the help of the toothed disc 302 meshing at their outer ends, providing power for crushing and grinding.

[0048] Initial crushing of raw materials: The crushing blades 201 on the rotating rod 2 rotate at high speed in the crushing chamber 102, crushing and refining the large volume of chemical raw materials fed from the feed hopper 101. The crushed raw materials fall into the grinding chamber 103 through the feeding channel 4.

[0049] Fine grinding of raw materials: Two grinding rods 3 drive the grinding rollers 301 to rotate in opposite directions, squeezing and grinding the raw materials falling into the grinding chamber 103 to achieve fine processing of the raw materials;

[0050] Cleaning of grinding roller 301: When it is necessary to clean grinding roller 301, rotate screw 603, and drive lifting support plate 602 to rise and fall smoothly along support rod 604 through threaded transmission belt 204, driving scraper plate 6 to move upward, so that scraper plate 6 is in contact with the outer surface of grinding roller 301, and in conjunction with the rotation of grinding roller 301, thoroughly scrape off the clumps of raw materials adhering to the surface.

[0051] Finally, the ground raw material falls onto the discharge filter plate 5 and is discharged from the discharge port 104.

[0052] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
