Description

Technical Field

[0001] This utility model relates to a corrugated, easy-to-clean, anti-clogging screen plate structure for coal preparation plants, belonging to the field of screen plate technology. Background Technology

[0002] Screening machines, as a major type of equipment in coal preparation plants, primarily function in grading, dewatering, and desliming during the washing and beneficiation process. In practice, traditional fixed screen plates and desliming screen plates, such as... Figure 1 As shown, the screen includes a rectangular first screen plate 1, with first crossbeams 2 evenly fixed in the middle of the first screen plate 1. Slotted holes 3 are formed in the first screen plate 1. Fibers detached from the conveyor belt and carried in the material easily adhere to the screen plate as it passes through the screen surface. Over time, this accumulation causes the screen slots to become clogged with a large amount of fiber, significantly reducing the screening efficiency and resulting in poor desliming. To maintain the desliming effect, the screen plate needs to be periodically removed to clean the adhered fibers. This cleaning process is tedious and increases the labor intensity of the workers. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a corrugated, easy-to-clean, anti-clogging screen plate structure for coal preparation plants, so as to solve the technical problems existing in the prior art.

[0004] The technical solution adopted by this utility model is as follows: a corrugated easy-to-clean anti-clogging screen plate structure for coal preparation plants, including a second screen plate and a third screen plate. The second screen plate includes a rectangular frame, and one or more second crossbeams are evenly fixed in the middle of the rectangular frame. Corrugated plates are evenly fixed between adjacent second crossbeams and between the outermost second crossbeam and the rectangular frame. The corrugated plates are perpendicular to the surface of the rectangular frame. The third screen plate is a polyurethane board, and circular holes are vertically opened on the third screen plate. The external dimensions of the third screen plate are the same as those of the second screen plate. The number of second screen plates is set to two, and the third screen plate is fixed between the two second screen plates.

[0005] Preferably, the second sieve plate is made of stainless steel.

[0006] Preferably, the second sieve plate and the third sieve plate are connected by bolts.

[0007] The beneficial effects of this utility model are:

[0008] 1. Compared with the prior art, after this utility model is put into use, each screen wire (corrugated plate) is independent of each other, and the two screen plates are connected by a polyurethane plate. The unique design structure not only improves the opening rate of the screen plate and allows materials to pass through quickly, but also makes it less likely for the screened materials to get stuck or stick, solving the problem of easy clogging of the screen plate. It effectively solves the problem of easy clogging and "lint" on the desliming screen and fixed screen, and cleaning is very convenient. Water can be used to wash away the fibers and other debris attached to the screen surface, reducing the tedious steps of disassembling the screen plate, cleaning and restoring it, reducing the labor intensity of employees, and improving the service life of the screen plate.

[0009] 2. Compared with existing technologies, traditional screen cleaning requires 2-3 people working together for 1-2 days to clean the fibers "hanging" off the screen. After this utility model is put into use, only 1 person is needed to clean the screen, reducing labor input. Based on cleaning 7 times a month, traditional screen cleaning requires about 28 man-days per month for this work. After this utility model is put into use, only 7 man-days are needed. At 150 yuan / man-day, the monthly labor cost can be saved by 3150 yuan. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] Example 1:

[0017] A corrugated, easy-to-clean, anti-clogging screen plate structure for coal preparation plants, such as... Figures 2-4 As shown, it includes a second sieve plate 4 and a third sieve plate, as follows: Figure 2As shown, the second sieve plate 4 includes a rectangular frame, with four second crossbeams 6 evenly fixed in the middle of the rectangular frame. Corrugated plates 6 are evenly fixed between adjacent second crossbeams 6 and between the outermost second crossbeam 6 and the rectangular frame, with the corrugated plates 6 perpendicular to the surface of the rectangular frame. The second sieve plate 4 is made entirely of stainless steel. The third sieve plate is a rectangular polyurethane board 7 with vertically opened circular holes 8. The external dimensions of the third sieve plate are the same as those of the second sieve plate 4. There are two second sieve plates 4, and the third sieve plate is sandwiched between the two second sieve plates 4. The second sieve plate 4 and the third sieve plate are connected by bolts.

[0018] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
