Abstract
Description
Technical Field
[0001] This utility model belongs to the field of refractory bricks and relates to wet grinding mill technology, specifically to an improved rotating arm platform structure for a wet grinding mill. Background Technology
[0002] In the refractory brick manufacturing process, the wet mill is used to grind and mix raw materials. It achieves grinding and mixing by rotating a rotating platform and rotating arms. However, this structure has some problems in practical applications, as follows:
[0003] 1. During the feeding process, some raw materials may remain on the rotating platform. Because the rotating platform has many uneven structures, it is very troublesome to clean it afterward, especially for dusty raw materials.
[0004] 2. During the rotation of the rotating platform, some of the raw materials remaining on the platform will be transferred into the machine chamber of the wet grinding mill. These raw materials and the raw materials in the machine chamber have different sizes and states, which makes the mixed raw materials uneven and results in poor material stability. The surface of the bricks formed by the press is not smooth, rough and has dense pores, which affects the forming effect of the bricks. Summary of the Invention
[0005] Purpose of the invention: In order to overcome the shortcomings of the existing technology, an improved rotating arm platform structure for a wet grinding mill is provided. This structure can prevent raw materials from accumulating on the rotating platform, eliminating the need for material cleaning operations on the rotating platform, saving a lot of time and reducing time costs. Furthermore, it can ensure the uniformity of the mixing of raw materials in the wet grinding mill, improve the mixing effect, guarantee the stability of the raw materials after mixing, and effectively guarantee the forming effect of the bricks.
[0006] Technical Solution: To achieve the above objectives, this utility model provides an improved rotating arm platform structure for a wet grinding mill, including a rotating arm and a rotating platform. A conical cover plate is provided on the top of the rotating platform, and several positioning bolts are provided on the top of the rotating platform. Positioning holes matching the positioning bolts are provided on the conical cover plate. The conical cover plate is fitted onto the positioning bolts through the positioning holes. At least one limiting nut is provided on the upper part of the positioning bolt of the conical cover plate. The limiting nut is used to longitudinally limit the conical cover plate. A spring is provided on the lower part of the positioning bolt of the conical cover plate. The spring is used to drive the conical cover plate to vibrate longitudinally.
[0007] Furthermore, the conical cover plate has a conical structure.
[0008] Furthermore, the maximum diameter of the conical cover plate is not less than the diameter of the rotating platform, ensuring that the conical cover plate can cover the rotating platform and prevent the raw materials on the conical cover plate from falling onto the rotating platform.
[0009] Furthermore, the number of positioning holes is six, and they are arranged radially symmetrically on the conical cover plate.
[0010] Furthermore, the number of positioning bolts is three and they are radially symmetrically arranged on the top of the rotating platform. The three positioning bolts have a triangular structure, which on the one hand ensures the support effect for the conical cover plate, and on the other hand leaves three positioning holes as spare holes. If the other positioning holes are worn, they can continue to be used simply by rotating the position.
[0011] Furthermore, the number of limiting nuts is two. When a single nut is fixed, the longitudinal elastic change of the spring causes vibration, which generates an upward pushing force on the nut, making it prone to loosening and falling off. Adding a nut can enhance the connection's firmness, and it is welded in place to prevent loosening during use and avoid safety accidents.
[0012] Beneficial effects: Compared with the prior art, during use, the raw material coming from the feed port passes over the upper surface of the conical cover plate. When the rotating arm and rotating platform of the wet mill rotate, due to the different stresses and the action of the spring, the conical cover plate can shake continuously. Combined with the conical structure of the conical cover plate, the raw material can slide along the surface of the conical cover plate into the machine chamber of the wet mill. This prevents the raw material from contacting and remaining on the rotating platform. Not only is there no need to clean the rotating platform, saving a lot of time and reducing time costs, but it also ensures the uniformity of the raw material mixing in the wet mill, improves the mixing effect, ensures the stability of the raw material after mixing, and effectively guarantees the forming effect of the brick.

[0016] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention. After reading the present invention, any modifications of the present invention in various equivalent forms by those skilled in the art will fall within the scope defined by the appended claims.
[0017] like Figures 1-3As shown, this utility model provides an improved rotating arm platform structure for a wet grinding mill, including a rotating platform 1, two rotating arms 2 located at the bottom of the rotating platform 1, and a conical cover plate 3 covering the top of the rotating platform 1. The conical cover plate 3 has a conical structure and its maximum diameter is not less than the diameter of the rotating platform 1. Six positioning holes 4 are radially symmetrically arranged on the conical cover plate 3. Three positioning bolts 6 are symmetrically arranged on the top of the rotating platform 1. The positioning bolts 6 match the positioning holes 4. The conical cover plate 3 is fitted onto the three positioning bolts 6 through the three positioning holes 4. The three positioning bolts 6 form an equilateral triangle structure, which on the one hand ensures the support effect for the conical cover plate 3, and on the other hand leaves three positioning holes 4 as spare holes. If other positioning holes are worn, they can be reused simply by rotating the position. Two limit nuts 7 are provided on the upper part of the positioning bolts 6 of the conical cover plate 3, and springs 5 are provided on the lower part of the positioning bolts 6 of the conical cover plate 3. The top of the springs 5 is attached to the conical cover plate 3.
[0018] In this embodiment, the positioning bolt 6 and the limiting nut 7 are of type M16. The length of the positioning bolt 6 is ≥16cm, of which the threaded length is 80mm. The spring 5 is made of ordinary alloy material, with an outer diameter of 30mm, an inner diameter of 20mm, and a free length of 80mm. The tapered cover plate 3 is made of 304 stainless steel.
[0019] In this embodiment, the aforementioned rotating arm platform structure is applied to a wet grinding mill. The rotating platform 1, rotating arm 2, and conical cover plate 3 are located inside the mill's chamber. This wet grinding mill is used to grind and mix the raw materials for refractory bricks. The specific process is as follows:
[0020] Reference Figures 1-3 The raw material falls from the feed port of the wet mill onto the conical cover plate 3. At this time, the rotating platform 1 and the rotating arm 2 are rotating. Due to the different stresses and the action of the spring 5, the conical cover plate 3 can shake continuously. With the conical structure of the conical cover plate 3, the raw material can slide along the surface of the conical cover plate 3 into the machine chamber of the wet mill. This prevents the raw material from contacting and remaining on the rotating platform 1. Not only is there no need to perform subsequent raw material cleaning operations on the rotating platform 1, saving a lot of time and reducing time costs, but it also ensures the uniformity of the raw material mixing in the wet mill, improves the mixing effect, ensures the stability of the raw material after mixing, and effectively guarantees the forming effect of the brick.
