Description

Technical Field

[0001] This utility model relates to the technical field of calcination cleaning devices, and in particular to a mobile ash hopper for calcination. Background Technology

[0002] The waste residue and dust generated during calcination need to be effectively collected and treated to ensure the continuity of production and the cleanliness of the environment. As a flexible and efficient collection device, the mobile ash hopper can play an important role in the calcination process. The mobile ash hopper is a movable device used to collect and transfer the waste residue and dust generated during combustion or calcination from the bottom or near the calcination equipment (such as rotary kilns, vertical preheaters, etc.).

[0003] When existing mobile ash hoppers are used to collect calcination ash, some ash contains hard particles or corrosive substances, which can easily cause wear or corrosion to the surface of the ash hopper. However, most of these ash hoppers are one-piece hoppers, and when the ash hopper is worn and damaged, it often needs to be replaced entirely, which is costly. Therefore, we propose a mobile ash hopper for calcination. Utility Model Content

[0004] The main objective of this invention is to provide a mobile ash hopper for calcination. A bucket-changing mechanism is installed in the ash hopper body, allowing for the presence of a replaceable inner bucket. This inner bucket can withstand hard particles or corrosive substances instead of the ash hopper body. If the inner bucket is damaged, it can be directly disassembled and replaced, thus avoiding direct damage and replacement of the ash hopper body from hard particles or corrosive substances. This significantly reduces the operating cost of the ash hopper body and effectively solves the problems in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A mobile ash hopper for calcination includes an ash hopper body and a hopper-changing mechanism. The hopper-changing mechanism includes an inner hopper, a fixed strip, a buffer pad, a screw-on hole, a screw column, a pressure plate, a fixed screw hole, a connecting frame, and a lifting handle. The inner hopper is inserted into the ash hopper body, and the outer wall surface of the inner hopper has a raised fixed strip. The inner wall of the ash hopper body has a fixed groove for inserting the fixed strip, and the ash hopper body below the inner hopper is filled with a buffer pad. The outer hopper body of the ash hopper body is fixed with a connecting frame, and the surface of the connecting frame has a screw-on hole for screwing on the screw column. The top of the screw column is welded with a pressure plate, and the pressure plate presses against the inner hopper body. The pressure plate and the surface of the inner hopper have fixed screw holes for screwing on fastening bolts, and a lifting handle is fixed to the inner wall of the inner hopper.

[0007] Furthermore, the inner wall of the ash hopper body is coated with a wear-resistant paint, and the outer wall of the inner hopper is pressed against the wear-resistant paint surface of the ash hopper body.

[0008] By adopting the above technical solution, the ash hopper body, with its wear-resistant paint surface, can have good wear resistance when in contact with the inner ash hopper, reducing frictional damage between the inner ash hopper and the ash hopper body.

[0009] Furthermore, the top of the three frame walls away from the inclined hopper opening of the ash hopper body are provided with fixed spiral holes, and a threaded column is screwed into the cavity of the fixed spiral hole.

[0010] By adopting the above technical solution, the three-sided frame wall of the connecting frame is opened with set rotating holes to allow the rotating column to be connected at multiple positions, so that the rotating column can support the pressure plate to press the inner changing bucket into the ash hopper body.

[0011] Furthermore, the three outer walls of the inner hopper are provided with fixed strips, and the three inner walls of the ash hopper body are provided with fixed grooves.

[0012] By adopting the above technical solution, the fixed grooves on the multi-sided hopper walls of the ash hopper body can be adapted to the fixed strips of the inner hopper for multi-directional clamping.

[0013] Furthermore, the vertical handle body of the lifting handle is welded inside the vertical bucket wall of the inner bucket changing, and an I-shaped handle is fixed outside the vertical handle body of the lifting handle.

[0014] By adopting the above technical solution, after the lifting handle is welded to the inner bucket with a vertical handle body, the I-shaped handle of the lifting handle can be gripped by hand, thereby lifting the inner bucket out of the ash hopper body.

[0015] Furthermore, the outer hopper body size of the inner hopper is smaller than the inner hopper cavity size of the ash hopper body;

[0016] By adopting the above technical solution, the bucket body of the internal bucket changer can be smoothly inserted into the ash bucket body.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This utility model provides a bucket-changing mechanism in the ash hopper body for calcination. The bucket-changing mechanism allows for the presence of a replaceable inner bucket inside the ash hopper body. The inner bucket can withstand hard particles or corrosive substances in place of the ash hopper body. After the inner bucket is damaged, it can be directly disassembled and replaced, thereby avoiding the ash hopper body from being directly subjected to hard particles or corrosive substances and thus avoiding damage and replacement. This greatly reduces the usage cost of the ash hopper body.

[0019] Furthermore, by utilizing the combination of rotating columns, pressure plates, and fixed rotating holes, the stability of the inner changing bucket within the ash hopper body can be ensured. This fastening method is not only simple and effective, but also prevents the inner changing bucket from shifting or falling off due to force during use. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1-2 As shown, a mobile ash hopper for calcination includes an ash hopper body 1 and a hopper-changing mechanism 2. The hopper-changing mechanism 2 includes an inner hopper 3, a fixing bar 4, a buffer pad 6, a screw-on hole 7, a screw-on column 8, a pressure plate 9, a fixed screw-on hole 10, a connecting frame 12, and a lifting handle 14. The inner hopper 3 is inserted into the ash hopper body 1, and the outer wall surface of the inner hopper 3 has a protruding fixing bar 4. A fixing groove 5 for inserting the fixing bar 4 is provided in the inner wall of the ash hopper body 1. The ash hopper body 1 below is filled with a buffer pad 6. A connecting frame 12 is fixed to the outer hopper body of the ash hopper body 1. The surface of the connecting frame 12 is provided with a screw-on hole 7 for screwing on the rotating column 8. A pressure plate 9 is welded to the top of the rotating column 8. The plate of the pressure plate 9 presses on the hopper body of the inner changing hopper 3. The pressure plate 9 and the surface of the inner changing hopper 3 are provided with a fixed screw hole 10 for screwing on the fastening bolt 11. A lifting handle 14 is fixed to the inner hopper wall of the inner changing hopper 3.

[0025] The inner wall of the ash hopper body 1 is coated with wear-resistant paint 13, and the outer wall of the inner changing hopper 3 is pressed against the wear-resistant paint 13 of the ash hopper body 1.

[0026] By adopting the above technical solution, the ash hopper body 1 with wear-resistant paint 13 can have good wear resistance when in contact with the inner ash hopper 3, reducing frictional damage between the inner ash hopper 3 and the ash hopper body 1.

[0027] Among them, the top of the three frame walls of the connecting frame 12 away from the inclined bucket opening of the ash bucket body 1 are provided with fixed rotating holes 10, and a threaded column of rotating column 8 is screwed into the cavity of the fixed rotating hole 10.

[0028] By adopting the above technical solution, the three-sided frame wall of the connecting frame 12 has set swivel holes 10, which can be swivelly connected to the swivel column 8 at multiple positions, so that the swivel column 8 can support the pressure plate 9 to press the inner changing bucket 3 into the ash bucket body 1.

[0029] Among them, the inner hopper 3 has three protruding outer walls with fixed strips 4, and the ash hopper body 1 has three recessed inner walls with fixed grooves 5.

[0030] By adopting the above technical solution, the fixed grooves 5 on the multi-sided hopper walls of the ash hopper body 1 can be adapted to the fixed strips 4 of the inner changing hopper 3 for multi-directional clamping.

[0031] The vertical handle of the lifting handle 14 is welded inside the vertical bucket wall of the inner bucket 3, and an I-shaped handle is fixed outside the vertical handle of the lifting handle 14.

[0032] By adopting the above technical solution, after the lifting handle 14 is welded to the inner hopper 3 with a vertical handle body, the I-shaped handle of the lifting handle 14 can be held by hand, thereby lifting the inner hopper 3 out of the ash hopper body 1.

[0033] Wherein, the outer bucket body size of the inner bucket 3 is smaller than the inner bucket cavity size of the ash bucket body 1;

[0034] By adopting the above technical solution, the bucket body of the inner changing bucket 3 can be smoothly inserted into the ash bucket body 1.

[0035] It should be noted that this utility model is a mobile ash hopper for calcination. A hopper-changing mechanism 2 is provided at the ash hopper body 1. When the ash hopper body 1 needs to collect calcination ash, the buffer pad 6 can be inserted into the ash hopper body 1, and then the inner hopper 3 can be inserted into the fixed groove 5 of the ash hopper body 1 by the fixed bar 4, so that the inner hopper 3 can be inserted into the ash hopper body 1. Then, the rotating column 8 can be screwed into the screw hole 7 of the connecting frame 12. At this time, the pressure plate 9 of the rotating column 8 can press the inner hopper 3 into the ash hopper body 1. Then, the pressure plate 9 and the fixed rotation hole 10 of the inner changing hopper 3 can be screwed together with the fastening bolt 11, so that the inner changing hopper 3 and the ash hopper body 1 are installed. At this time, the inner changing hopper 3 can normally collect the ash slag used for calcination, while the ash hopper body 1 can move at the ash cleaning slide rail by the sliding seat under the hopper body. When the inner changing hopper 3 in the ash hopper body 1 is damaged, the fastening bolt 11 can be unscrewed, and then the rotating column 8 can be rotated counterclockwise so that the pressure plate 9 can leave the inner changing hopper 3. At this time, the lifting handle 14 can be held to lift the inner changing hopper 3 out of the ash hopper body 1 for replacement.

[0036] It should be noted that this utility model is a mobile ash hopper for calcination. All components in this utility model are known to those skilled in the art, and their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.
