Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of ball mill feeding devices, specifically to a modular and detectable ball mill feeding trolley. Background Technology
[0002] Ball mills are key pieces of equipment used for further pulverizing materials after they have been crushed. Suitable for grinding various ores and other materials, ball mills are widely used in mineral processing, building materials, and chemical industries. They can be divided into dry and wet grinding methods. During the feeding process, ball mills require the use of a feeding trolley.
[0003] The existing ball mill feed trolley has the following problems during use:
[0004] 1. The existing feeding trolley's feeding bend is a closed structure, making it impossible to determine the internal wear during use, which causes difficulties in equipment maintenance.
[0005] 2. The existing feeding trolley's feeding bend is a one-piece cast structure, which cannot be fitted with wear-resistant liners. When the wear is severe, the entire trolley needs to be replaced, which increases the operating cost.
[0006] 3. The height of the feed bend of the existing feed trolley is fixed, and one feed trolley can only adapt to one type of ball mill, resulting in poor adaptability and high operating costs.
[0007] Therefore, in order to solve the above-mentioned problems of the existing ball mill feed trolley, it is now urgent to improve the existing ball mill feed trolley. Summary of the Invention
[0008] To address the shortcomings of existing technologies, this utility model presents a modular and detectable ball mill feeding trolley that enables visual detection of wear conditions, eliminates the need to replace the outer shell of the bent pipe, allows for segmented replacement of the wear-resistant liner, and features adjustable bending pipe height.
[0009] The technical solution of this utility model is as follows:
[0010] A modular, detectable ball mill feeding trolley includes a track, a support mechanism mounted on the track, and a feeding bend mounted on the support mechanism. The feeding bend includes a feed pipe, a connecting pipe, and a discharge pipe connected in sequence. An observation box is connected to the bottom of the feed pipe and communicates with the feed pipe, connecting pipe, and discharge pipe. The bottom plate of the observation box is horizontally positioned and its height is lower than the opening of the connecting pipe. Some particles in the slurry will accumulate on the bottom plate, forming a protective layer that reduces the impact of the slurry on the feeding bend. Because the slurry contains moisture, the particles accumulated on the bottom plate will gradually be washed into the bend and discharged; however, a small amount of particles is allowed to accumulate on the bottom plate.
[0011] Furthermore, the observation box includes a base plate, a first side plate, a second side plate, a top plate, and a window plate. The base plate is horizontally positioned, and the first and second side plates are vertically positioned on both sides of the base plate and fixedly connected to the outer wall of the feed pipe. The top plate fixes the top of the first and second side plates to the outer wall of the feed pipe. The opening formed by the base plate, first side plate, second side plate, and top plate is the observation port, which is perpendicular to the base plate. The window plate is detachably installed at the observation port. Adding an observation box facilitates the observation of the wear condition of the wear-resistant liner of the feed pipe. Regular inspection of the observation box allows for timely detection of internal problems in the feed bend, enabling early repair and replacement of the wear-resistant liner and reducing maintenance costs.
[0012] Furthermore, the base plate and window plate are configured as rectangular structures, and the first side plate and the second side plate are configured as having the same shape and as irregular pentagonal structures.
[0013] Furthermore, the inner walls of the feed pipe, connecting pipe, and discharge pipe are respectively provided with detachable feed wear-resistant liners, connecting wear-resistant liners, and discharge wear-resistant liners.
[0014] Furthermore, the feed wear-resistant liner includes an upper feed wear-resistant liner and a lower feed wear-resistant liner, which are interference-fitted together. The connecting wear-resistant liner includes a bottom wear-resistant liner and two side wear-resistant liners located on both sides of the bottom wear-resistant liner, which are interference-fitted together. The discharge wear-resistant liner includes an upper discharge wear-resistant liner and a lower discharge wear-resistant liner, which are interference-fitted together. This segmented wear-resistant liner structure facilitates individual replacement of damaged sections, reducing operating costs.
[0015] Furthermore, the outlet pipe is equipped with a liner baffle that protrudes from the wear-resistant liner. This ensures that the wear-resistant liner will not shift horizontally within the bend.
[0016] Furthermore, the support mechanism includes an upper bracket, a lower bracket, and wheels. The upper bracket is fixedly connected to the lower bracket, and the wheels are fixed to the lower bracket and connected to a track. The depth of the feed bend into the ball mill inlet can be adjusted. A fixing plate is provided on the side wall of the feed bend, and the fixing plate is fixed to the upper bracket. A removable adjusting shim is provided between the fixing plate and the upper bracket. By adjusting the thickness of the adjusting shim, the height of the feed bend outlet can be changed to ensure that it is on the same horizontal plane as the center of the ball mill inlet.
[0017] Furthermore, the inner wall of the observation box is lined with wear-resistant rubber. This prevents wear on the observation box and avoids leakage of the slurry.
[0018] Furthermore, at least one connecting pipe is provided.
[0019] Furthermore, the material of the material wear-resistant liner, the connecting wear-resistant liner, and the discharge wear-resistant liner is high-manganese rolled wear-resistant steel plate (ZGMn13).
[0020] The beneficial effects achieved by this utility model are as follows:
[0021] 1. This utility model, by installing an observation box on the feed bend, facilitates the observation of wear conditions inside the feed bend. Regular inspection of the observation box allows for timely detection of internal problems, enabling prompt repair and replacement of the wear-resistant liner, thus reducing maintenance costs. Furthermore, the bottom plate of the observation box is horizontally positioned and its height is lower than the inlet of the connecting pipe. Some particles within the slurry will accumulate on the bottom plate, forming a protective layer, which reduces the impact of the slurry on the feed bend and minimizes wear.
[0022] 2. Existing integrally cast feed bends are incompatible with segmented wear-resistant liners; the liners cannot be installed. Integral feed bends require integral wear-resistant liners, resulting in significant weight, large dimensions, and operational difficulties. The feed bend in this invention is segmented and welded, facilitating the installation of wear-resistant liners. Furthermore, the segmented structure of the wear-resistant liners allows for individual replacement of damaged sections, reducing operating costs. Since the wear-resistant liners inside the feed bend can be replaced after a certain degree of wear, the outer shell of the feed bend can be used indefinitely, reducing maintenance and operating costs.
[0023] 3. This utility model, through the adjustment of the shims, allows for the alteration of the height of the feed bend outlet during use by adjusting the thickness of the shims, ensuring that it is on the same horizontal plane as the center of the ball mill feed inlet. This enables the use of multiple machines on a single vehicle, reducing operating costs. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0038] like Figures 1-6 As shown, this utility model provides a modular and detectable ball mill feeding trolley, including a feeding bend 1, a support mechanism 2, a track 3, an adjusting shim 4, and a wear-resistant liner 5.
[0039] In this embodiment, the feed bend 1 includes pipe segment 11, pipe segment 12, pipe segment 13, pipe segment 14, observation box flange 15, observation box 17, and liner baffle 18. Pipe segment 11 is the feed pipe, and pipe segments 12 and 13 are connecting pipes. In this embodiment, the feed pipe is set to two segments, but in actual application, the design can be adjusted according to the actual situation and is not limited to two segments. Pipe segment 14 is the discharge pipe. Pipe segments 11, 12, 13, and 14 are welded and fixed horizontally by cutting at an angle of 8-20°. The feed end flange of pipe segment 11 is parallel to the hopper flange. The observation box flange 15 is connected and fixed to the observation box 17 by bolts 16. The inner wall of the observation box flange 15 is lined with wear-resistant rubber to prevent wear of the observation box flange 15 and leakage of slurry. The liner baffle 18 is connected and fixed to the pipe section 14 and protrudes from the wear-resistant liner 5, which can ensure that the wear-resistant liner 5 will not have horizontal displacement inside the pipe.
[0040] Specifically, in this embodiment, the observation box 17 further includes a base plate 171, a first side plate 172, a second side plate 173, a top plate 174, and an observation port 175. The base plate 171 and the observation port 175 are rectangular structures. The first side plate 172 and the second side plate 173 have the same shape and are irregular pentagonal structures. The base plate 171 is horizontally positioned, and the first side plate 172 and the second side plate 173 are vertically positioned on both sides of the base plate 171 and fixedly connected to the outer wall of the pipe section 11. The top plate 174 fixes the top of the first side plate 172 and the second side plate 173 to the outer wall of the pipe section 11. The opening formed by the base plate 171, the first side plate 172, the second side plate 173, and the top plate 174 is the observation port 175, which is perpendicular to the base plate 171. The observation box flange 15 is detachably mounted on the observation port 175. An observation box 17 is added to facilitate observation of the wear condition of the wear-resistant liner 5 inside the feed bend 1. By regularly inspecting the observation box 17, problems inside the feed bend 1 can be detected in time, and the wear-resistant liner 5 can be repaired and replaced as soon as possible, thereby reducing maintenance costs.
[0041] In this embodiment, the wear-resistant liner 5 is configured as a segmented structure. At the end of the pipe segment 14, there is a liner baffle 18. A groove is cut into the inner wall of the pipe segment 14, and the liner baffle 18 is inserted into the groove. The liner baffle 18 prevents the wear-resistant liner 5 inside the feed bend 1 from moving outwards. When replacing the wear-resistant liner 5, the liner baffle 18 must be removed first, and then the wear-resistant liner inside must be pulled out. Normally, the wear-resistant liner 5 does not need special fixing to the feed bend 1 because the wear-resistant liner 5 is not cylindrical in shape; the segments are mutually restrained and interlocked, so it will not rotate inside the feed bend 1 after installation. The wear-resistant liner 5 cannot rotate as a whole, nor can it rotate individually; therefore, a single liner baffle 18 is sufficient to ensure the stability of all wear-resistant liners 5.
[0042] Specifically, the inner walls of the feed pipe, connecting pipe, and discharge pipe are respectively provided with detachable feed wear-resistant liners, connecting wear-resistant liners, and discharge wear-resistant liners. In this embodiment, a feed wear-resistant liner 51 is provided on the inner wall of pipe section 11. The feed wear-resistant liner 51 includes an upper feed wear-resistant liner 511 and a lower feed wear-resistant liner 512, which are press-fitted and stacked together. Connecting wear-resistant liners 52 are respectively provided on the inner walls of pipe sections 12 and 13. The connecting wear-resistant liner 52 includes a bottom wear-resistant liner 521 and two side wear-resistant liners 522 disposed on both sides of the bottom wear-resistant liner 521, which are press-fitted and stacked together. The inner wall of pipe section 14 is provided with a discharge wear-resistant liner 53, which includes an upper discharge wear-resistant liner 531 and a lower discharge wear-resistant liner 532. The upper discharge wear-resistant liner 531 and the lower discharge wear-resistant liner 532 are connected by interference fit and stacking. The segmented structure of the wear-resistant liner facilitates the individual replacement of damaged parts of the wear-resistant liner, reducing the cost of use.
[0043] In this embodiment, the support mechanism 2 includes an upper bracket 21, a lower bracket 22, and wheels 23. The upper bracket 21 and the lower bracket 22 are connected by bolts. The wheels 23 can travel on the track 3 and can adjust the depth of the feed bend 1 into the ball mill inlet.
[0044] The adjusting shim 4 is made in various thicknesses, with the appropriate thickness selected based on height requirements. By adjusting the thickness of the adjusting shim 4, the height of the discharge port of the feed bend 1 can be changed, ensuring it is on the same horizontal plane as the center of the ball mill inlet. Specifically, the adjusting shim 4 is bolted to the upper support 21 and the fixing plates on both sides of the pipe section 12. When the adjusting shim 4 needs to be replaced, the replaced adjusting shim 4 is bolted to the upper support 21 and the fixing plates on both sides of the pipe section 12 through the two connecting holes at both ends, achieving a detachable connection.
[0045] In this embodiment, the wear-resistant liner 5 is manufactured in different sizes to match the internal dimensions of pipe sections 11, 12, 13, and 14, ensuring no wear on the pipe wall when the slurry flows through. The wear-resistant liner in this embodiment is made of high-manganese rolled wear-resistant steel plate (ZGMn13).
[0046] The operation process of the ball mill feeding trolley in this embodiment is as follows: The support mechanism 2 of the ball mill feeding trolley is moved and the thickness of the adjusting shims 4 is adjusted to ensure that the ball mill feeding trolley is in a suitable position. The slurry enters through the feed inlet of the feeding bend 1 and is discharged through the discharge outlet. Some particles of the slurry will accumulate on the bottom surface of the observation box 17, which can reduce the impact of the slurry on the feeding bend 1. Because the slurry contains water, the particles accumulated on the bottom plate 171 will gradually be washed into the bend and then discharged. However, a small amount of particles are allowed to accumulate on the bottom plate 171. During maintenance, the bolts 16 can be removed to open the flange 15 of the observation box to observe the wear condition of the wear-resistant liner 5 inside the feeding bend 1. If the wear is severe, it can be replaced with a new wear-resistant liner 5.
[0047] The embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
