Description

Technical Field

[0001] This utility model relates to the field of high-pressure grinding technology, specifically to a high-pressure grinding mill for bentonite preparation. Background Technology

[0002] The high-pressure grinding mill for bentonite preparation mainly consists of a main unit, an analyzer, a blower, a piping system, a feeder, and a dust collector. The main unit contains grinding rollers and grinding rings. During operation, bentonite is fed into the main unit by the feeder. Under centrifugal force, the grinding rollers swing outwards and press tightly against the grinding rings. The shovels lift the material and feed it between the grinding rollers and the grinding rings. The blower circulates air within the system. The material is crushed and ground between the grinding rollers and the grinding rings. The fine powder after grinding is carried by the airflow through the pipes into the analyzer. The analyzer uses rotating blades to screen the fine powder. Fine powder that meets the particle size requirements is collected by the dust collector through the pipes.

[0003] Current high-pressure grinding mills used for bentonite preparation suffer from insufficient dust and residue collection capabilities. This leads to environmental pollution, with large amounts of dust escaping into the workshop, worsening air quality, harming operators' health, and increasing the risk of respiratory diseases. It also results in material waste, as uncollected and scattered material cannot be reused, increasing production costs. Furthermore, it affects normal equipment operation, as dust easily enters the high-pressure grinding mill, accelerating component wear, shortening equipment lifespan, and potentially causing equipment malfunctions and reducing production efficiency. Additionally, existing high-pressure grinding mills may not grind finely enough, resulting in substandard product quality that cannot meet the stringent requirements for bentonite particle size and fineness in applications such as high-end chemicals and precision casting, thus limiting the product's application scope. Finally, it increases the difficulty of subsequent processing; if downstream processes require finer raw materials, re-grinding is necessary, increasing energy consumption and processing costs, and potentially affecting the performance and quality of subsequent processed products.

[0004] Therefore, this utility model provides a high-pressure grinding mill for bentonite preparation. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a high-pressure grinding mill for bentonite preparation, which solves the technical problems in the prior art.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The high-pressure grinding mill for bentonite preparation described in this utility model uses a first motor to drive the transmission gear to rotate, and then the rotation drives the screw to rotate and lift along the threaded hole, thereby reducing the distance between the third grinding rod and the grinding wall, thus improving the grinding accuracy. Finally, the ground material is ground again by the grinding hammer below, thereby avoiding the problem of substandard product quality and failure to meet the particle size requirements of bentonite due to insufficient grinding of the material.

[0016] 2. The high-pressure grinding mill for bentonite preparation described in this utility model, through the design of adding a collection mechanism to one side of the device, allows the dust generated during grinding to be guided into the device by a fan. Then, liquid is sprayed from the nozzle, causing the dust to adhere to the liquid surface and fall into the discharge tray below, thereby collecting the dust and avoiding pollution of the working environment. Large amounts of dust escaping into the workshop deteriorate air quality, endanger the health of operators, and increase the risk of respiratory diseases; it also causes material waste, as the flying and uncollected residual material cannot be reused, increasing production costs.

[0031] A vent pipe is installed at the connection between the cylinder wall 6 and the recycling machine 1, and the vent pipe passes through the recycling machine 1 and is located on the top side of the recycling machine 1; two sets of fans 25 are provided on one side of the recycling machine 1; a water storage tank 3 is provided at the top of the recycling machine 1; the output end of the water storage tank 3 is connected to a water inlet pipe 28, and the bottom of the water inlet pipe 28 is connected to six sets of nozzles 29, which are located inside the recycling machine 1; two sets of second motors 23 are provided on both sides inside the recycling machine 1, and screws are connected inside the second motors 23. The screw is spirally connected to a filter screen 24; the bottom of the filter screen 24 is provided with a discharge tray 26; a rectangular perforation is opened on one side of the recycling machine 1, and the discharge tray 26 is installed inside the rectangular perforation; a flow guide platform 27 is provided at the bottom of the inside of the recycling machine 1, the flow guide platform 27 is designed with a slope, and the bottom of the flow guide platform 27 is connected to the water outlet 2; the top of the positioning rod 4 penetrates the cylinder wall 6 and is placed outside the cylinder wall 6; the two sides of the second positioning plate 12 and the first positioning plate 8 are fixedly connected to the inner wall of the cylinder wall 6.

[0032] Working principle: This high-pressure grinding mill for bentonite preparation achieves fine grinding through a unique grinding structure design. When bentonite enters the grinding chamber 20 inside the cylinder wall 6 through the feed inlet 5, the first motor 11 starts, and the drive gear 10 connected to its output end begins to rotate. The drive gear 10 meshes with the transmission gear 9, driving the transmission gear 9 to rotate. The rotation of the transmission gear 9 causes the first positioning plate 8 and the connected positioning rod 4, which are engaged with it, to rotate and rise within the threaded hole 19. The rise of the positioning rod 4 causes the first grinding rod 13, the second grinding rod 14, and the third grinding rod 15 connected below to move closer to the grinding wall 22, reducing the distance between the third grinding rod 15 and the grinding wall 22, thereby improving the grinding accuracy. The material initially ground by the grinding rods and the grinding wall 22 falls onto the grinding hammer 18 and the grinding plate 17 below for further grinding. This design avoids the problem of substandard product quality and inability to meet the particle size requirements of bentonite due to insufficient grinding. This grinding mill... The effective collection of dust and residual materials is achieved through a collection mechanism set on one side of the device. During the grinding process, two sets of fans 25 on one side of the recycling machine 1 start working. The fans 25 guide the dust generated during grinding into the interior of the recycling machine 1 through the ventilation pipe at the connection between the cylinder wall 6 and the recycling machine 1. At this time, the six sets of nozzles 29 at the bottom of the water pipe 28 connected to the output end of the water tank 3 at the top of the recycling machine 1 start spraying liquid. The sprayed liquid causes the dust entering the recycling machine 1 to adhere to its surface and then fall into the filter screen 24 below. The filter screen 24 can be adjusted appropriately under the action of the screw driven by the second motor 23 on both sides inside the recycling machine 1. The dust and residual materials filtered by the filter screen 24 fall into the discharge tray 26 at the bottom for collection. The liquid flows along the sloping flow platform 27 at the bottom of the recycling machine 1 to the outlet 2 for discharge. In this way, the problems of dust escaping into the workshop, polluting the working environment, endangering the health of operators, and causing material waste and increased production costs are avoided.
