Description

Technical Field

[0001] The present invention relates to the technical field of material dust removal, and particularly to a dust removal device for a Raymond mill. Background Art

[0002] A Raymond mill, also known as a Raymond powder mill, is a device for high-precision powder processing of materials in industries such as minerals, chemicals, and construction. Specifically, it can be applied to the processing of non-explosive and non-flammable materials with a Mohs hardness of no more than 9.3 and a humidity of less than 6%, such as barite, calcite, potassium feldspar, talc, marble, limestone, dolomite, etc.

[0003] Patent Publication No. CN119656729A discloses a dust removal device for a Raymond grinder, including a housing, a bracket, a filter bag, and a knocking assembly; the bracket is fixed inside the housing, and the filter bag is sleeved outside the bracket; the knocking assembly is arranged inside the filter bag and includes a track ring and a knocking rod. The knocking rod is slidably installed on the bracket and is connected to the bracket through an elastic member. A plurality of track grooves are formed on the track ring, and all the track grooves are coaxial with the rotation axis of the track ring and have gradually increasing diameters; a through groove communicating with the plurality of track grooves is also formed on the track ring; the knocking rod reciprocally moves under the restriction of the elastic member and the wave peak grooves and wave valley grooves in the track grooves to impact the filter bag. When the convex block gradually moves from the track groove with the smallest diameter to the track groove with the largest diameter, the impact of the knocking rod on the filter bag changes from low-frequency heavy impact to high-frequency light impact, which is adapted to the clogging situation of the filter bag, can reduce the damage to the filter bag, ensure the cleaning effect, and extend the service life of the filter bag.

[0004] When the Raymond mill is working for powder processing, it is necessary to separate the dust in the material to avoid the situation where the quality of the powder decreases due to the mixing of dust in the powder. Currently, the existing dust separation methods are similar to the above device, generally simply using a pulse dust collector or other methods for dust removal. The disadvantage of using such a device for dust removal is that the cloth bag is prone to clogging and needs to be cleaned repeatedly, which easily leads to low processing efficiency. Moreover, after the material is ground into powder, it is difficult to control the difference in particle diameters between the powder particles and the dust particles, and it is easy to have insufficient screening of dust and powder particles during the filtering process. Therefore, a dust removal device for a Raymond mill is proposed here to solve the above problems. Summary of the Invention

A material guiding hopper 461 is fixedly connected between the first vertical plate 41 and the second vertical plate 42. The material guiding hopper 461 is arranged at the bottom of the cylinder 43. The material guiding hopper 461 is arranged on the top of the screening frame 491. A material receiving plate 462 is fixedly connected to the top of the platform plate 3. The material receiving plate 462 is arranged at the bottom of the screening frame 491. The material guiding hopper 461 receives the materials discharged from the cylinder 43.

[0037] A vibration assembly 6 is arranged on the top of the bottom plate 1. The vibration assembly 6 includes a U-shaped plate 61. The U-shaped plate 61 is fixedly connected to the top of the bottom plate 1. The U-shaped plate 61 is arranged outside the platform plate 3. A round rod 62 is rotatably connected to the inside of the U-shaped plate 61. A knocking wheel 63 is fixedly connected to the outside of the round rod 62.

One end of the spring 65 is fixedly connected to the bottom of the platform plate 3. After the knocking wheel 63 rotates, it knocks on the platform plate 3.

[0038] In the actual operation process, when this device is in use, first connect the device to the power supply. Before the preliminarily crushed materials are fed into the Raymond mill for powder grinding operation, first feed the materials into the cylinder body 43 through the opening at the top of the cylinder body 43. Subsequently, cover the sealing cover 51 on the opening. Then, insert the fixing plate 53 through the two limiting plates 52 in sequence until one of the limiting plates 52 fits against the wider side of the fixing plate 53. During the insertion process of the above fixing plate 53, the inclined surface on the clamping block 54 is squeezed and enters the fixing plate 53. When the clamping block 54 moves to one side of the limiting plate 52, the reed piece 55 pushes out the clamping block 54. At this time, the clamping block 54 limits the fixing plate 53, and the fixing plate 53 tightly presses the sealing cover 51 on the outside of the cylinder body 43 to complete the sealing; After the above operations are completed, the first motor 498 operates and drives the second gear 499 to rotate. The second gear 499 drives the first gear 497 to rotate. The first gear 497 drives the cylinder body 43 to rotate. During the rotation of the cylinder body 43, the materials tumble inside the cylinder body 43 and form a beating effect when touching the barrier strips 44 during the tumbling process, prompting the impurities such as dust and mud adhering to the outer surface of the materials to be quickly peeled off. At the same time, after the fan 46 operates, it generates suction, prompting the dust particles agitated inside the cylinder body 43 to be quickly sucked into the inside of the frame body 45. After falling on the inclined mesh plate 481, they slide into the space separated by the partition plate 482 for storage; During the process of the above dust being sucked away, the grille plate 485 allows the dust to pass through and blocks the material blocks to prevent the materials from falling into the inside of the frame body 45 together. At the same time, when the outside air enters, the gas passes through the filter net 486. The filter net 486 filters the dust in the air. And during the rotation of the cylinder body 43, since the scraping plate 489 is always in contact with the filter net 486, it can also achieve the effect of scraping and cleaning the filter net 486 in all directions to ensure the permeability of the filter net 486. The dust cleaned out can be discharged through the dust discharge plate 488, effectively ensuring that the materials are not contaminated; Finally, after the above dust adsorption operation is completed, the sealing cover 51 can be removed by repeating the above similar operations. During the subsequent continuous flipping of the cylinder body 43, when the opening on the cylinder body 43 faces downward, the materials are continuously discharged downward. The material guide hopper 461 receives the materials, prompting the materials to accurately fall into the screening frame 491. At this time, the screening frame 491 further screens out the large particle impurities in the above materials that have not been adsorbed sufficiently. Such large particle impurities fall on the material receiving plate 462 after passing through the screening frame 491, while the materials continue to stay in the screening frame 491; When the above-mentioned screening frame 491 screens the materials and large particle impurities, in order to improve the screening quality and efficiency, the second electric push rod 477 repeatedly pushes and pulls the lifting plate 476. The lifting plate 476 drives the rack 479 to move, the rack 479 drives the third gear 478 to rotate, the third gear 478 drives the connected connecting rod 492 to rotate, and this connecting rod 492 drives the screening frame 491 to swing repeatedly. During the swinging process, the materials roll in the screening frame 491 to accelerate the falling of large particle dust; After the above-mentioned material screening is completed, after the first electric push rod 484 works, it pushes the moving block 494. The moving block 494 drives the mounting rod 495 to move. After the mounting rod 495 drives the receiving hopper 496 to move to the bottom of the screening frame 491, after controlling the discharge port on the screening frame 491 to incline downward to the receiving hopper 496, the second motor 474 works and drives the bidirectional threaded rod 473 to rotate. The second bidirectional threaded rod 473 drives the two auxiliary plates 472 to move away from each other. The auxiliary plates 472 drive the baffle 471 to move. At this time, the materials can be discharged downward through the discharge port and fall into the receiving hopper 496. And the discharge end of the receiving hopper 496 is above the receiving port of the screw conveyor 2, so the materials can smoothly enter the screw conveyor 2. After the screw conveyor 2 works, it can quickly convey the dust-removed materials in the direction not shown in the Raymond mill device diagram for the front-end dust removal operation, which can effectively reduce the dust volume in the materials and reduce the dust removal pressure during the subsequent Raymond mill powder grinding, improving the processing efficiency; Finally, after the large particle dust screened out by the above-mentioned screening frame 491 falls on the receiving plate 462, it can slide down to the discharge end of the receiving plate 462. After further opening the door plate 483 on the frame body 45, the dust particles collected in the frame body 45 can also be discharged to the outside of the frame body 45. The user only needs to receive the discharged dust for unified cleaning, which provides convenience for the dust cleaning work and can also avoid the situation of dust scattering and polluting the environment; In order to improve the discharge efficiency of the above-mentioned dust and avoid dust residue, after the third motor 64 works, it drives the round rod 62 to rotate. The round rod 62 drives the knocking wheel 63 to repeatedly knock the platform plate 3. Since the spring 65 also has an elastic acting force on the platform plate 3, the platform plate 3 will drive the frame body 45 and the receiving plate 462 to shake after being knocked. During the shaking process, the dust can be quickly discharged and fall.

[0039] The above are all the preferred embodiments of the present invention, and the protection scope of the present invention is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
