Description

Technical Field

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

[0002] The partition screen of a cement mill is a key internal component used to separate different grinding chambers and screen materials. The partition screen is usually assembled from multiple fan-shaped grates inside the mill cylinder, and is securely connected to the mounting base on the mill cylinder wall by high-strength bolts.

[0003] In existing installation processes, the connection between grates and the fixing between grates and cylinder often rely on a large number of bolts or on-site welding.

[0004] This traditional connection method has obvious drawbacks: bolt installation requires individual alignment and tightening of each bolt, which is extremely inconvenient and time-consuming within the confined space of the mill cylinder. Furthermore, under the harsh operating conditions of strong vibration, high dust, and high wear in cement mills, bolts are prone to loosening or becoming stuck due to material corrosion, making subsequent maintenance and grate replacement exceptionally difficult and severely impacting the operating efficiency and ease of maintenance of the cement mill.

[0005] Therefore, this utility model proposes a cement mill partition plate screen to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a cement mill partition plate screen, which aims to improve the problems of existing cement mill partition plate screens where the grates are fixed by bolts or welding, resulting in inconvenient assembly, difficult disassembly, and low maintenance efficiency.

[0007] This utility model provides a cement mill partition screen, including: a grate plate and an assembly mechanism.

[0008] The assembly mechanism has the structural feature of enabling rapid sliding and splicing of adjacent grate plates.

[0009] Furthermore, the assembly mechanism is connected between adjacent grate plates. The assembly mechanism includes a fixing strip and an alignment strip. The fixing strip is fixedly connected to one end face of the grate plate, and the alignment strip is fixedly connected to the other end face of the grate plate. A central block extending along the length direction is fixedly connected inside the fixing strip. The central block divides the interior of the fixing strip to form a slot extending along the length direction. A groove extending along the length direction is opened on the surface of the alignment strip. A sliding connection is formed between the central block and the groove, and a sliding connection is formed between the solid part of the alignment strip and the slot.

[0010] Preferably, the cross-sectional shape of the center block is adapted to the cross-sectional shape of the groove, and the cross-sectional shape of the solid part of the alignment strip is adapted to the cross-sectional shape of the slot, thereby ensuring smooth sliding during assembly and tight fit after connection.

[0011] Preferably, the center blocks are symmetrically distributed at the center of the fixing strip, and the slots are symmetrically distributed on both sides of the center blocks. This symmetrical design helps with positioning during installation and makes the structure more evenly stressed.

[0012] Preferably, the slot passes through both ends of the fixing strip, and the groove passes through both ends of the alignment strip, allowing it to slide in from either end during assembly, thus improving the convenience of on-site operation.

[0013] Preferably, the fixing strip and the grate are fixedly connected by welding, which ensures the firmness of the connection between the basic components of the assembly mechanism and the grate body and the structural integrity.

[0014] Preferably, the grate has a fan-shaped structure, and multiple grates are sequentially assembled by an assembly mechanism to form a circular partition plate to accommodate the circular installation space of the cement mill cylinder.

[0015] Preferably, the surface of the grate is provided with a number of sieve holes, which are used to screen and flow the grinding material during the operation of the cement mill.

[0016] Preferably, the grate, fixing bars, and alignment bars are all made of wear-resistant alloy steel to resist the high wear conditions of materials inside the cement mill and extend the overall service life.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model, by setting up an assembly mechanism, utilizes the double sliding engagement structure formed by the center block, groove, slot and solid part on the fixing strip and the alignment strip, which solves the problem of cumbersome, time-consuming and difficult maintenance caused by the use of bolts or welding to fix the grate plates in the prior art. It achieves the technical effect of quick assembly and disassembly without tools, greatly improves the efficiency of installation and maintenance, and reduces maintenance costs.

[0019] 2. This utility model, through the cooperation of the central block and the groove, and the cooperation of the alignment strip and the slot, forms a double locking between adjacent grate plates, which solves the problem that the existing connection method is prone to loosening or failure under vibration conditions, and achieves the technical effect of a stable connection structure, high reliability, and effective resistance to the vibration of cement mill operation.

[0020] 3. This utility model integrates complex connection functions into the fixing strips and alignment strips on both sides of the grate, replacing the scattered parts such as bolts and nuts required for traditional connections, thus achieving the technical effect of compact overall structure, fewer parts, easy manufacturing and on-site management.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example:

[0029] Reference Figures 1 to 3 This utility model provides a cement mill partition plate screen, which aims to solve the problem that the existing cement mill partition plate screen is fixed by bolts or welding, resulting in cumbersome and time-consuming installation and replacement operations and low maintenance efficiency.

[0030] like Figures 1 to 3 As shown, the assembly includes a grate plate 1 and an assembly mechanism 2. The assembly mechanism 2 is connected between adjacent grate plates 1 to enable rapid sliding splicing of adjacent grate plates 1. The assembly mechanism 2 includes a fixing strip 21 and an alignment strip 24. The fixing strip 21 is fixedly connected to one end face of the grate plate 1, and the alignment strip 24 is fixedly connected to the other end face of the grate plate 1. A central block 22 extending along the length direction is fixedly connected inside the fixing strip 21. The central block 22 divides the interior of the fixing strip 21 to form a slot 23 extending along the length direction. A groove 25 extending along the length direction is opened on the surface of the alignment strip 24. The central block 22 is slidably connected inside the groove 25, and the solid part of the alignment strip 24 is slidably connected inside the slot 23.

[0031] Reference Figure 2 and Figure 3The assembly mechanism 2 includes a fixing strip 21 and an alignment strip 24. The fixing strip 21 has slots 23 extending along its length and separated by a center block 22. The fixing strip 21 is fixedly connected to one end face of the grate plate 1.

[0032] Meanwhile, the alignment strip 24 is correspondingly provided with a groove 25 extending along its length direction, and the alignment strip 24 is fixedly connected to the other end face of the grate plate 1.

[0033] In the assembled state, the center block 22 of the fixing strip 21 is slidably fitted inside the groove 25 of the alignment strip 24, and the solid part of the alignment strip 24 is slidably fitted inside the slot 23 of the fixing strip 21, ensuring high stability and reliable connection of adjacent grate plates 1 during the assembly process.

[0034] The cross-sectional shape of the center block 22 is adapted to the cross-sectional shape of the groove 25, and the cross-sectional shape of the solid part of the alignment strip 24 is adapted to the cross-sectional shape of the slot 23. The center block 22 is symmetrically distributed at the center of the fixing strip 21, and the slot 23 is symmetrically distributed on both sides of the center block 22. The slot 23 passes through both ends of the fixing strip 21, and the groove 25 passes through both ends of the alignment strip 24. The fixing strip 21 and the grate plate 1 are fixedly connected by welding. The grate plate 1 has a fan-shaped structure. Multiple grate plates 1 are sequentially spliced ​​by the assembly mechanism 2 to form a circular partition plate. The screen holes are used to screen and flow materials. The grate plate 1, the fixing strip 21 and the alignment strip 24 are all made of wear-resistant alloy steel.

[0035] The implementation principle of this application embodiment is as follows: When it is necessary to install or splice the grate 1, the fixing strip 21 of one grate 1 is aligned with the alignment strip 24 of the adjacent grate 1 and slid relative to each other along the length direction. During the sliding process, the center block 22 on the fixing strip 21 will slide into the groove 25 of the alignment strip 24. At the same time, the solid part of the alignment strip 24 will slide into the slot 23 of the fixing strip 21. Since a tight sliding fit is formed between the center block 22 and the groove 25, and between the solid part of the alignment strip 24 and the slot 23, this double sliding engagement structure can quickly and firmly connect the two grate 1 together. When it is necessary to replace, the grate 1 can be disassembled by simply sliding in the opposite direction. Through this sliding engagement structure of the assembly mechanism 2, this utility model solves the problems of cumbersome installation, time-consuming installation and difficult maintenance caused by bolt or welding fixation in the prior art.
