Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary tools for calcium carbide production, in particular to a chute for coke. Background Art

[0002] Lime is one of the key raw materials for producing calcium carbide. Specifically, the production of calcium carbide relies primarily on limestone (primarily composed of calcium carbonate, which decomposes into calcium oxide upon heating, also known as quicklime) and coke or semi-coke. In a calcium carbide furnace, lime (in the form of calcium oxide) and coke or semi-coke are smelted at high temperatures. The electrical energy between electrodes creates resistance, and the arc converts this heat into heat, which then undergoes a chemical reaction, producing calcium carbide.

[0003] One of the raw materials used in the production of calcium carbide is coke. During its transportation, coke often passes through chute pipes, which play a crucial role in the material conveying system, primarily used to transfer bulk materials between different conveying systems. Chute pipes are typically made of stainless steel, and coke has a rough surface and is very hard. When it comes into contact with and rubs against steel, it can easily cause wear. As coke passes through the chute, it rubs against the inner wall of the pipe, causing wear. Over time, this damage can lead to leakage. Utility Model Content

[0004] The purpose of the utility model is to provide a coke chute to solve the problem that the inner wall of the coke chute is worn due to long-term contact with coke.

[0005] In order to achieve the above-mentioned purpose, the basic solution provided by the utility model is: a chute for coke, including a feed pipe, the feed pipe is connected to a discharge pipe 1 and a discharge pipe 2, the bottom of the discharge pipe 1 and the discharge pipe 2 are flange-connected with pipe segments 1 and pipe segments 2 respectively, the inner walls of the discharge pipe 1 and the discharge pipe 2 are respectively provided with wear-resistant plates 1 and 2, and the wear-resistant plates 1 and 2 are respectively provided with a number of evenly distributed storage plates 1 and 2.

[0006] The principle and beneficial effects of this utility model are as follows: by arranging wear-resistant plates on the inner walls of the two discharge pipes of the chute, and arranging evenly distributed storage plates on the wear-resistant plates, a portion of the coke will be retained on the storage plates as the coke flows through the chute. When the coke on the storage plates accumulates to a certain level, the subsequent coke will come into contact with the coke on the storage plates without wearing out the inner wall of the chute. The arrangement of the wear-resistant plates and storage plates allows a portion of the coke to be retained on the storage plates, which is equivalent to isolating the flowing coke from the inner wall of the chute, preventing the coke from wearing out the inner wall of the chute.

[0007] Option 2, the preferred basic option, has each accumulator plate 1 and wear plate 1 angled at 30°, and each accumulator plate 2 and wear plate 2 angled at 30°. Setting the angle between the accumulator plates and the wear plates at 30° allows the accumulator plates to accumulate more coke faster, and coke remaining in the accumulator plates is not easily carried away by the coke flow, ensuring that there is always coke on the accumulator plates, reducing material waste to a certain extent.

[0008] Option 3, a preferred option over Option 2, has support plate 1 fixed to each first storage plate, support plate 2 fixed to each second storage plate, support plate 1 fixed to wear-resistant plate 1, and support plate 2 fixed to wear-resistant plate 2. The support plates make the storage plates more stable and extend their service life.

[0009] Option 4, which is a preferred option of the basic option, is that each flange connection is a tooth-type flange connection. The tooth-type flange connection makes the connection between the discharge pipe and the pipe joint tighter, thereby preventing coke from leaking from the connection between the discharge pipe and the pipe joint.

[0010] Option 5, a preferred alternative to the basic option, has nuts fixed to opposite sides of one end of wear-resistant plate 1 near the inlet pipe. Discharge pipe 1 has through-holes on opposite sides, each with a bolt movably inserted through it. Each bolt is threadedly connected to a nut. Wear-resistant plate 2 and discharge pipe 2 are provided with nuts, through-holes, and bolts identical to those on wear-resistant plate 1 and discharge pipe 1. The threaded connection of the bolts and nuts secures one end of wear-resistant plate 1 and wear-resistant plate 2 within discharge pipe 1 and discharge pipe 2, making it easy to remove the bolts and remove wear-resistant plate 1 and wear-resistant plate 2 when needed.

[0011] Option 6, a preferred alternative to the basic option, features support plates 3 fixed to the inner walls of opposite sides of pipe segment 1. Each support plate 3 abuts against the end of wear plate 1 facing away from the inlet pipe. Pipe segment 2 also features support plates 3, similarly configured as those on pipe segment 1. The provision of support plates 3 facilitates blocking the lower ends of wear plates 1 and 2. When removing wear plates 1 and 2 from discharge pipes 1 and 2, they are prevented from sliding out instantly when the bolts are removed. Instead, they are held in place by support plates 3, facilitating safe removal. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Example

[0020] like Figures 1 to 5 As shown: A chute for coke, including a feed pipe 1, the feed pipe 1 is connected to a discharge pipe 2 and a discharge pipe 3, the bottoms of the discharge pipe 2 and the discharge pipe 3 are flange-connected with a pipe segment 4 and a pipe segment 5 respectively, each flange connection is a tooth-type flange connection, and the inner walls of the discharge pipe 2 and the discharge pipe 3 are provided with a wear-resistant plate 6 and a wear-resistant plate 7 respectively.

[0021] Nuts 12 are welded on both sides of the opposite end of the wear-resistant plate 6 close to the inlet pipe 1, and through holes 13 are provided on the opposite sides of the discharge pipe 2. A bolt 14 is movably passed through each through hole 13, and each bolt 14 is threadedly connected to the nut 12. The wear-resistant plate 27 and the discharge pipe 23 are provided with nuts 12, through holes 13 and bolts 14 arranged in the same manner as those on the wear-resistant plate 6 and the discharge pipe 2. Support plates 3 15 are welded on the inner walls on both sides of the opposite sides of the pipe segment 4. Each support plate 3 15 is fitted with the end of the wear-resistant plate 6 away from the inlet pipe 1, and the pipe segment 25 is fixed with a support plate 3 15 arranged in the same manner as that on the pipe segment 4.

[0022] Several evenly distributed storage plates 1 8 and storage plates 2 9 are welded to the wear-resistant plate 1 6 and the wear-resistant plate 2 7 respectively. The angle between each storage plate 1 8 and the wear-resistant plate 1 6 is 30°, and the angle between each storage plate 2 9 and the wear-resistant plate 2 7 is 30°. Each storage plate 1 8 is welded with a support plate 10, and each storage plate 2 9 is welded with a support plate 2 11.

[0023] The implementation method of this embodiment is as follows:

[0024] When the coke flows through the chute, part of the coke remains on the storage plate 1 8 and the storage plate 2 9. As time accumulates, the storage plate 1 8 and the storage plate 2 9 are filled with coke, and the later coke will come into contact with the coke on the storage plate 1 8 and the storage plate 2 9.

[0025] When it is necessary to remove the wear-resistant plate 1 6 and the wear-resistant plate 2 7 from the discharge pipe 1 2 and the discharge pipe 2 3, first loosen the bolt 14, then remove the bolt 14 from the through hole 13, then pull out the end of the wear-resistant plate 1 6 and the wear-resistant plate 2 7 that is in contact with the support plate 3 15 until it exceeds the range of the support plate 3 15, and then pull out the wear-resistant plate 1 6 and the wear-resistant plate 2 7 obliquely downward.
