Description

Technical Field

[0001] This utility model relates to the field of cement mill technology, and in particular to a cement mill partition plate structure. Background Technology

[0002] A cement mill is a device used to grind cement clinker with appropriate amounts of gypsum and other additives into powder. Its main function is to grind materials to a certain fineness through mechanical force to meet the requirements of cement production. A cement mill partition plate is a plate-like structure installed inside the mill cylinder to separate different grinding sections. Its main function is to divide the grinding space into multiple compartments to control the particle size and grinding efficiency of the material at different grinding stages.

[0003] Although the technology has many advantages, its disadvantage is that when the cement mill's partition plates are working, a large amount of material will adhere to the inside of the partition plates, which can easily cause screen blockage and greatly reduce screening efficiency. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a cement mill partition plate structure.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A cement mill partition plate structure, comprising: The first and second unblocking plates are symmetrically arranged on both sides of the rotating shaft; The rotating shaft is rotatably mounted on the cement mill partition plate, and the first and second unblocking plates are in close contact with the surface of the cement mill partition plate.

[0006] Both the first and second unblocking boards have a fan-shaped structure.

[0007] The cement mill partition plate includes: The main body has several sieve holes distributed in a ring on it; Several reinforcing rods are arranged in a ring on the motherboard body.

[0008] The side wall of the cement mill partition plate is provided with several fixing plates, and each fixing plate is provided with bolt holes.

[0009] This utility model also includes a partition plate, which is set behind the cement mill partition plate and located behind the first and second unblocking plates, and has a number of screens distributed in a ring on it.

[0010] The partition plate is provided with a ring of several supporting ribs.

[0011] The beneficial effects of this utility model are: 1. In this utility model, when the cement mill is working, the cement mill partition plate rotates accordingly, and the main body also rotates. Larger particles are blocked outside the main body, while smaller particles enter the cement mill partition plate through the sieve holes and then pass through the sieve openings in the partition plate. At the same time, the first and second unblocking plates also rotate due to friction. When they reach the highest point, they fall rapidly due to their own weight, discharging the smaller particles, while the larger particles return to the main body to continue grinding.

[0012] 2. In this utility model, when the cement mill partition plate is in use, the cement mill partition plate can be easily disassembled through the fixing plate, and the damaged partition plate can be easily replaced, thereby achieving the purpose of quick disassembly and replacement of the cement mill partition plate.

[0013] 3. The outer surface of the cement mill partition plate of this utility model is fixedly installed with multiple fixing plates distributed in a circle, and bolt holes are opened in the interior of each fixing plate. Through the bolt holes, bolts can be used to fix the fixing plate to other parts, which facilitates the disassembly and replacement of the partition plate.

[0014] 4. Multiple reinforcing rods are installed inside the cement mill diaphragm plate to increase the strength and stability of the diaphragm plate, which helps to evenly distribute the pressure from the material and inside the mill, and ensures the stability of its shape and function.

[0015] 5. The sieve opening can effectively promote airflow circulation inside the cement mill and help to distribute the airflow evenly.

[0016] 6. The first unblocking plate effectively prevents material from accumulating or clogging in the central area, ensuring that the material can flow smoothly to the next chamber or grinding area. A second unblocking plate is set on the opposite side of the first unblocking plate. Both the second unblocking plate and the first unblocking plate are fan-shaped. The second unblocking plate can effectively reduce the risk of blockage in the center or other areas inside the cement mill. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0020] like Figures 1 to 4 As shown, a cement mill partition plate structure includes: a first unblocking plate 201 and a second unblocking plate 202, symmetrically arranged on both sides of a rotating shaft; wherein the rotating shaft is rotatably mounted on the cement mill partition plate 1, and the first unblocking plate 201 and the second unblocking plate 202 are in close contact with the surface of the cement mill partition plate 1. Both the first unblocking plate 201 and the second unblocking plate 202 are fan-shaped structures. The cement mill partition plate 1 includes: a main body 101, on which a plurality of sieve holes 103 are distributed in a ring; a plurality of reinforcing rods 102, which are arranged in a ring on the main body 101. A plurality of fixing plates 4 are provided on the side wall of the cement mill partition plate 1, and each fixing plate 4 is provided with bolt holes 401. This utility model also includes a partition plate 301, which is arranged on the rear side of the cement mill partition plate 1 and located behind the first unblocking plate 201 and the second unblocking plate 202, and has a plurality of sieve holes 303 distributed in a ring on it. A plurality of supporting ribs 302 are arranged in a ring on the partition plate 301.

[0021] In use, when material enters the cement mill, the mill begins to rotate and grind. The collision and compression between the grinding media and the material grind the cement raw material to the required fineness. At this time, the cement mill partition plate 1 rotates under the action of the cement mill, and the main body 101 also rotates. Larger particles are blocked outside the main body 101, while finer particles begin to enter the interior of the cement mill partition plate 1 through the sieve holes 103 in the main body 101. Then, they pass through the partition plate 301 for the next processing step. When the cement mill partition plate 1 rotates, the first unblocking plate 201... After the second unblocking plate 202 starts to rotate due to friction, the first unblocking plate 201 and the second unblocking plate 202 quickly fall due to their own gravitational potential energy, thereby discharging the smaller particles inside the cement mill partition plate 1 through the sieve 303 and discharging the larger particles inside the cement mill partition plate 1 to the outside of the main body 101 for continued grinding. This cycle repeats continuously. When the cement mill partition plate 1 is in use, it can be easily disassembled through the fixing plate 4, and damaged partition plates can be easily replaced, thus achieving the purpose of quick disassembly and replacement of the cement mill partition plate 1.

[0022] The cement mill partition plate 1 has a first unblocking plate 201 near the center, and a second unblocking plate 202 on the opposite side of the first unblocking plate 201. Both the second unblocking plate 202 and the first unblocking plate 201 are fan-shaped. When the first unblocking plate 201 and the second unblocking plate 202 rise due to friction, they can swing at different frequencies due to their own gravitational potential energy to avoid blockage.

[0023] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
