Description

Technical Field

[0001] The invention relates to the technical field of chemical production equipment, in particular to a chemical raw material grinding device with an automatic cleaning function. Background Art

[0002] In the chemical industry, the grinding process of raw materials is a crucial part of production. Existing technologies usually use traditional grinding equipment, most of which rely on a single grinding method to grind the raw materials to the desired particle size through mechanical force. However, this method faces many problems in practical applications. First, traditional equipment often has the phenomenon of material accumulation or blockage during the grinding process, resulting in low equipment efficiency. This not only requires frequent manual cleaning, which increases operating costs, but also causes unstable grinding effects and uneven particle sizes, thus affecting the quality of the final product. Secondly, due to the lack of an effective automatic cleaning mechanism, the frequency of equipment downtime maintenance has increased significantly, further affecting production efficiency.

[0003] In addition, existing grinding devices usually lack adaptability to different material characteristics and cannot maintain good performance in processing raw materials with different viscosities and particle sizes. This makes the performance of the equipment even worse when processing high-viscosity or easily agglomerated chemical raw materials, resulting in instability in the production process.

[0004] Therefore, those skilled in the art have proposed a chemical raw material grinding device with automatic cleaning function to solve the above problems. Summary of the invention

[0011] Preferably, it also includes a scraper assembly, which includes a connecting plate, the connecting plate is fixedly connected to the outer side of the movable frame, the inner side of the connecting plate is fixedly connected to two mounting plates, the inner side of the mounting plate is rotatably connected to a connecting shaft, the outside of the connecting shaft is fixedly connected to a scraper, the inner side of the connecting plate is fixedly connected to a plurality of tension springs, and the outer side of the connecting plate is fixedly connected to a limiting plate.

[0012] Preferably, one end of the tension spring is fixedly connected to the inner side of the scraper, and the lower surface of the scraper is in contact with the outer surface of the grinding roller.

[0013] Preferably, the knocking assembly includes a driving disk, which is fixedly connected to one end of one of the crushing rollers, a connecting rod is rotatably connected to the outer eccentric portion of the driving disk, one end of the connecting rod is rotatably connected to a movable rod, the outer side of the movable rod is slidably connected to a support plate, the support plate is fixedly connected to the outer side of the machine body, and a knocking seat is fixedly connected to the rear side of the machine body.

[0014] Preferably, the anti-blocking component includes a fixed cylinder, which is fixedly connected to the inner side of the machine body, a cavity is opened on the inner side of the fixed cylinder, a feed groove is opened on the outer surface of the fixed cylinder, and a discharge groove is opened on the outer surface of the fixed cylinder, the discharge groove and the feed groove are symmetrically arranged, the interior of the fixed cylinder is rotatably connected to a drive shaft, and the outer side of the drive shaft is fixedly connected to a plurality of discharge plates.

[0016] Working principle: To use this device, first place the chemical raw materials on the top of the fixed box, then start the first motor to rotate the driving gear. Since the driving gear and the two driven gears are meshed with each other, the rotation of the driven gear drives the two crushing rollers to rotate, and the crushed materials enter the outer surface of the arc filter through the lower hopper. By starting the second motor to rotate the driving thread, the thread seat is moved back and forth along the outer surface of the driving thread. During the movement of the thread seat, the movable frame is driven to move synchronously, thereby driving the fixed shaft to move. Since the fixed shaft moves along the inner wall of the arc groove, the grinding roller is driven to move along the outer surface of the arc filter during the movement of the fixed shaft. At this time, during the movement of the grinding roller, the connecting gear is driven to move synchronously. Since the connecting gear and the arc-shaped tooth plate are meshed with each other, the connecting gear will drive the grinding roller to rotate when it moves, so that the crushed chemical raw materials are crushed again to obtain powder of chemical raw materials that meet the standard size, reducing the repeated operations in the traditional grinding method and improving the overall processing efficiency; After grinding, the chemical raw material powder enters the cavity through the filter holes of the arc filter and the feed trough. At this time, the rotation of the driving thread drives the first synchronous wheel to rotate, and under the transmission of the synchronous belt, drives the second synchronous wheel and the driving shaft to rotate, thus driving the discharge plate to rotate, and the materials in the cavity are discharged from the discharge trough in turn, realizing the anti-blocking function; When the fine grinding assembly is working, the scraper always fits the outer surface of the grinding roller under the elastic force of the tension spring. Therefore, as the grinding roller rotates, the lower surface of the scraper will scrape off the powder adhering to the outer surface of the grinding roller, without manual cleaning. This can effectively reduce the downtime caused by manual cleaning, so that the equipment can continue to operate efficiently, thereby improving the overall production efficiency; In addition, the driving disk will be driven to rotate during the rotation of the crushing roller, which will drive one end of the connecting rod to swing. At this time, under the action of the traction force of the connecting rod, the movable rod is driven to move up and down repeatedly, thereby driving the knocking block at the bottom of the movable rod to repeatedly knock the knocking seat, causing the machine body to vibrate, and finally realizing the vibration of the arc filter to prevent the arc filter from being blocked.

[0017] The present invention provides a chemical raw material grinding device with automatic cleaning function. It has the following beneficial effects: 1. The present invention adds a crushing component and then cooperates with a fine grinding component to crush the chemical raw materials and drop them on the outer surface of the arc filter. The reciprocating movement of the grinding roller realizes the fine grinding of the chemical raw materials, which can more effectively process the chemical raw materials to the required particle size, reduce the repeated operations in the traditional grinding method, and improve the overall processing efficiency. In addition, the device can ensure that the chemical raw materials maintain a high consistency and uniformity during the grinding process, reducing the product quality fluctuation caused by uneven particle size.

[0018] 2. The present invention adds a knocking component, which can achieve vibration knocking on the arc filter during the use of the fine grinding component. The vibration knocking can effectively break and loosen the particles attached to the filter to prevent their accumulation and clogging, ensuring the normal operation of the equipment and reducing the frequency of shutdown maintenance.

[0019] 3. The present invention can automatically clean the materials adhered to the outer surface of the grinding roller by adding a cleaning component without manual cleaning. This can effectively reduce the downtime caused by manual cleaning, allowing the equipment to continue to operate efficiently, thereby improving overall production efficiency.

[0020] 4. The present invention can smoothly discharge the ground chemical raw materials by adding a material discharge anti-blocking component, which can effectively reduce the downtime caused by material blockage and ensure the smooth outflow of chemical raw materials, thereby improving the efficiency of the entire production process. The overall operation is simple and convenient for staff to operate and use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Please see attached Figure 1 - Attachment Figure 8 The embodiment of the present invention provides a chemical raw material grinding device with automatic cleaning function, comprising: A machine body 1, which serves as a support carrier for the entire device, and a door 4 is connected to the outer side of the machine body 1 via a hinge; A crushing assembly, which is installed on one side of the top of the machine body 1 and is used to crush the chemical raw materials; The crushing assembly includes a fixed box 201, which is fixedly connected to one side of the top of the machine body 1. Two crushing rollers 202 are rotatably connected to the inner side of the fixed box 201, and one end of the crushing roller 202 is fixedly connected to a driven gear 203. A first motor 205 is installed on the outside of the fixed box 201, and the output end of the first motor 205 is fixedly connected to a driving gear 204. The outer sides of the driving gear 204 are respectively meshed with the outer sides of the two driven gears 203. The bottom end of the fixed box 201 is fixedly connected to a lower hopper 206.

[0025] Specifically, the chemical raw materials are placed on the top of the fixed box 201. At this time, the driving gear 204 is rotated by starting the first motor 205. Since the driving gear 204 is meshed with the two driven gears 203, the rotation of the driven gears 203 drives the two crushing rollers 202 to rotate and the crushing rollers 202 crush the raw materials.

[0026] A fine grinding assembly, which is mounted on the upper surface of the machine body 1 and is used to grind the crushed raw materials; The fine grinding assembly includes two mounting seats 603, the inner sides of the two mounting seats 603 are each provided with an arc groove 604, the inner wall of the arc groove 604 is rollingly connected with a fixed shaft 607, the outer side of the fixed shaft 607 is fixedly connected with a grinding roller 601, one end of the fixed shaft 607 is fixedly connected with a connecting gear 606, the outer side of the body 1 is fixedly connected with an arc tooth plate 605, and the top of the body 1 is fixedly connected with an arc filter 602.

[0027] The outer side of the connecting gear 606 is meshed and connected with the outer side of the arc-shaped tooth plate 605 , and the outer surface of the grinding roller 601 is in contact with the outer surface of the arc-shaped filter screen 602 .

[0028] Specifically, the fixed shaft 607 is driven to move under the driving assembly. Since the fixed shaft 607 moves along the inner wall of the arc groove 604, the grinding roller 601 is driven to move along the outer surface of the arc filter 602 during the movement of the fixed shaft 607. At this time, during the movement of the grinding roller 601, the connecting gear 606 is driven to move synchronously. Since the connecting gear 606 and the arc tooth plate 605 are meshed with each other, the connecting gear 606 drives the grinding roller 601 to rotate when it moves, so that the pulverized chemical raw materials are crushed again to obtain powder of chemical raw materials that meet the standard size, reducing the repeated operations in the traditional grinding method and improving the overall processing efficiency.

[0029] A striking assembly mounted on the outside of the pulverizing assembly for vibrating the fine grinding assembly; The striking assembly includes a driving disk 801, which is fixedly connected to one end of one of the crushing rollers 202. A connecting rod 802 is rotatably connected to the outer eccentric portion of the driving disk 801. One end of the connecting rod 802 is rotatably connected to a movable rod 803. The outer portion of the movable rod 803 is slidably connected to a support plate 804. The support plate 804 is fixedly connected to the outer side of the body 1. A striking seat 805 is fixedly connected to the rear side of the body 1.

[0030] An anti-blocking component, which is installed inside the body 1 and is used to ensure the normal feeding of chemical raw materials; The anti-blocking component includes a fixed cylinder 301, which is fixedly connected to the inner side of the body 1. A cavity 304 is provided on the inner side of the fixed cylinder 301. A feed groove 306 is provided on the outer surface of the fixed cylinder 301. A discharge groove 305 is also provided on the outer surface of the fixed cylinder 301. The discharge groove 305 and the feed groove 306 are symmetrically arranged. The interior of the fixed cylinder 301 is rotatably connected to a drive shaft 302, and a plurality of discharge plates 303 are fixedly connected to the outer side of the drive shaft 302.

[0031] Specifically, during the operation of the equipment, the ground chemical raw material powder enters the feed trough 306 through the filter holes of the arc filter 602, and then flows into the cavity 304. As the driving thread 702 rotates, the first synchronous wheel 901 is driven to rotate, and the power is transmitted to the second synchronous wheel 903 through the synchronous belt 902, and finally the driving shaft 302 rotates accordingly. The rotation of the driving shaft 302 drives the multiple discharge plates 303 to rotate, forming a continuous pushing action. This process enables the material inside the cavity 304 to be discharged from the discharge trough 305 in turn, ensuring that the material can flow efficiently and continuously. This design significantly reduces the possibility of material blockage and ensures that the grinding equipment can operate continuously and stably.

[0032] The driving assembly is installed on the outside of the machine body 1 and is used to drive the fine grinding assembly.

[0033] The driving assembly includes a second motor 701, which is fixedly connected to the outside of the body 1. The output end of the second motor 701 is fixedly connected to a driving thread 702, the outer side of the driving thread 702 is threadedly connected to a threaded seat 703, the outside of the threaded seat 703 is fixedly connected to a movable frame 704, and a movable groove 705 is opened on the inner side of the movable frame 704.

[0034] Specifically, by starting the second motor 701 to rotate the driving thread 702, the threaded seat 703 is moved back and forth left and right along the outer surface of the driving thread 702. During the movement of the threaded seat 703, the movable frame 704 is driven to move synchronously, thereby driving the fixed shaft 607 to move, because the fixed shaft 607 moves along the inner wall of the arc groove 604.

[0035] The scraper assembly further includes a connecting plate 504, which is fixedly connected to the outside of the movable frame 704, two mounting plates 503 are fixedly connected to the inside of the connecting plate 504, a connecting shaft 505 is rotatably connected to the inside of the mounting plate 503, a scraper 502 is fixedly connected to the outside of the connecting shaft 505, a plurality of tension springs 506 are fixedly connected to the inside of the connecting plate 504, and a limiting plate 501 is fixedly connected to the outside of the connecting plate 504. One end of the tension spring 506 is fixedly connected to the inside of the scraper 502, and the lower surface of the scraper 502 is in contact with the outer surface of the grinding roller 601.

[0036] Specifically, the connecting plate 504 provides a stable support platform for the scraper assembly. The two mounting plates 503 fixedly connected inside the connecting plate 504 are used to further support the movement of the scraper 502 and ensure the close contact between the scraper 502 and the grinding roller 601. The design of the mounting plate 503 allows the connecting shaft 505 to rotate freely inside it.

[0037] Limiting plate 501: The limiting plate 501 is fixed on the outside of the connecting plate 504, and plays a role in stabilizing the movement of the scraper 502, preventing the scraper 502 from being displaced or falling off during operation. Its design ensures that the scraper 502 is always within a reasonable working range during operation.

[0038] When the fine grinding assembly is working, the elastic force provided by the tension spring 506 ensures that the scraper 502 always fits the outer surface of the grinding roller 601. As the grinding roller 601 rotates, the lower surface of the scraper 502 can continuously and effectively scrape off the powder attached to the surface of the grinding roller 601. This process does not require manual intervention, greatly reducing the downtime caused by manual cleaning, so that the equipment can continue to operate efficiently.

[0039] It also includes a transmission assembly, which includes a first synchronous wheel 901 and a second synchronous wheel 903. The first synchronous wheel 901 is fixedly connected to one end of the driving thread 702, and the second synchronous wheel 903 is fixedly connected to one end of the driving shaft 302. The outer side of the first synchronous wheel 901 is connected to the outer side of the second synchronous wheel 903 through a synchronous belt 902.

[0040] Specifically, in actual operation, the rotation of the driving thread 702 drives the rotation of the first synchronous wheel 901 through the first synchronous wheel 901. Since the first synchronous wheel 901 and the second synchronous wheel 903 are connected by the synchronous belt 902, when the first synchronous wheel 901 rotates, the generated power is transmitted to the second synchronous wheel 903 through the synchronous belt 902. This process causes the second synchronous wheel 903 to rotate, thereby driving the connected driving shaft 302 to rotate. Through this efficient power transmission mechanism, the transmission assembly can effectively support the operation of various functions of the grinding device.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
