Description

Technical Field

[0001] This utility model relates to the field of electromechanical equipment and automation, specifically to a slide lubrication system for a coal charging device and a tamping coke oven. Background Technology

[0002] The coking industry currently mainly uses two types of coke ovens: tamping coke ovens and top-charging coke ovens. The core technology of tamping coke ovens lies in first tamping loose coal into a dense coal cake, and then loading this coal cake into the carbonization chamber from the side of the coke oven. There are two main types of coal charging equipment configurations to achieve this process: one is a separate unit consisting of a tamping station, a coal charging car, and a coke pushing car; the other is a multi-functional integrated locomotive that integrates tamping, coal charging, and coke pushing functions into one unit. Regardless of whether a separate or integrated unit is used, the core coal charging method and equipment structure are basically the same.

[0003] The operation of the coal charging device relies on a power unit driving a ring chain, on which a coal charging plate and its connecting seat are fixedly mounted. The power unit drives the chain, which in turn pulls the coal charging plate to reciprocate on the support beam, thus pushing the coal cake placed on it laterally into the carbonization chamber. Since the ring chain is a single-chain structure, the guidance of the coal charging plate during operation is mainly ensured by the inside of the coal box and the fixed guide plate at the rear of the device. When the coal charging plate and connecting seat move on the support beam, their bottoms come into contact with the slide rails on the beam, creating friction. Therefore, the quality of lubrication of the slide rails is a key factor in ensuring a smooth coal charging process and the complete and successful loading of the coal cake into the carbonization chamber.

[0004] Current lubrication technology uses two pneumatic lubrication pumps to supply oil to the front ends of the slides on both sides of the coal charging plate. If one of the pumps fails, the oil supply to one side of the slide will be interrupted, resulting in uneven lubrication on one side. This leads to uneven frictional resistance on both sides, causing the coal charging plate to deviate or become obstructed and impacted on the slides. Furthermore, the impact movement of the coal charging plate causes the coal cake to move intermittently and unstablely within the carbonization chamber. This unstable movement easily leads to cracking or even collapse of the coal cake structure, ultimately resulting in a significantly increased collapse rate, severely impacting production efficiency and coke quality.

[0005] Therefore, there is still room for improvement in existing technologies. Utility Model Content

[0006] The main purpose of this utility model is to provide a slide lubrication system for a coal charging device and a tamping coke oven, so as to solve the problem of increased coal cake collapse rate caused by poor slide lubrication in the prior art.

[0007] According to one aspect of this utility model, a slide lubrication system for a coal charging device is provided, comprising: Oil storage tank; The slide rail is provided with a first lubricating oil hole and a second lubricating oil hole; A first distributor connected to the first lubricating oil hole and a second distributor connected to the second lubricating oil hole; A first pneumatic lubrication pump and a second pneumatic lubrication pump are installed on the top of the oil storage tank. The first pneumatic lubrication pump is connected to the first distributor to deliver lubricating oil in the oil storage tank to the first lubricating oil hole. The second pneumatic lubrication pump is connected to the second distributor to deliver lubricating oil in the oil storage tank to the second lubricating oil hole.

[0008] According to one embodiment of the present invention, the slide lubrication system further includes a first pump outlet pipeline and a second pump outlet pipeline. The first pump outlet pipeline is connected to the first pneumatic lubrication pump and the first distributor at both ends, and the second pump outlet pipeline is connected to the second pneumatic lubrication pump and the second distributor at both ends.

[0009] According to one embodiment of the present invention, the slide lubrication system further includes a first valve and a second valve. The first valve is disposed on the first pump outlet pipeline, and the second valve is disposed on the second pump outlet pipeline. When the first valve is open, it delivers lubricating oil to the first lubricating oil hole through the first pump outlet pipeline. When the second valve is open, it delivers lubricating oil to the second lubricating oil hole through the second pump outlet pipeline.

[0010] According to one embodiment of the present invention, the slide lubrication system further includes a connecting pipeline and a third valve disposed on the connecting pipeline. The connecting pipeline is disposed between the first pump outlet pipeline and the second pump outlet pipeline. When the first valve is closed, the third valve is opened to deliver lubricating oil to the first lubricating oil hole through the connecting pipeline. When the second valve is closed, the third valve is opened to deliver lubricating oil to the second lubricating oil hole through the connecting pipeline.

[0011] According to one embodiment of the present invention, the slide rail lubrication system further includes a first pneumatic triplet and a second pneumatic triplet. The first pneumatic triplet is connected to the first pneumatic lubrication pump to output gas to the first pneumatic lubrication pump, and the second pneumatic triplet is connected to the second pneumatic lubrication pump to output gas to the second pneumatic lubrication pump.

[0012] According to one embodiment of the present invention, the slide rail lubrication system further includes a first air line and a second air line, wherein the first air line is connected to the first pneumatic triplet and the first pneumatic lubrication pump at both ends, and the second air line is connected to the second pneumatic triplet and the second pneumatic lubrication pump at both ends.

[0013] According to one embodiment of the present invention, the oil storage tank further includes a pressure cap, a sliding rod, and a detection sensor. The pressure cap is movably disposed inside the oil storage tank and moves with the rise and fall of the lubricating oil level inside the oil storage tank. The first end of the sliding rod is fixed to the upper surface of the pressure cap, and the second end extends out of the top of the oil storage tank and is movably connected thereto. The second end is provided with a sensing plate, and the detection sensor is disposed on the top of the oil storage tank.

[0014] According to one embodiment of the present invention, the first lubricating oil hole is disposed at a first preset position of the slide rail, and the second lubricating oil hole is disposed at a second preset position of the slide rail. The coal charging device slides back and forth between the initial position and the extreme position of the slide. When the coal charging device is in the initial position, the first bevel of the coal charging plate in the coal charging device is the first preset position. When the coal charging device is in the extreme position, the second bevel of the connecting seat in the coal charging device is the second preset position.

[0015] According to another aspect of the present invention, a tamping coke oven is provided, including a coal charging device and a slide lubrication system for the coal charging device of the tamping coke oven as described above.

[0016] In this invention, two pneumatic lubrication pumps, each working in conjunction with a corresponding distributor, deliver lubricating oil to the front and middle sections of the slideway, forming an independent yet coordinated multi-path oil supply mechanism. This effectively avoids the one-sided oil supply defect that often occurs in existing technologies where two pneumatic lubrication pumps only supply oil to the front of the slideway. Even if one pump or distributor fails, the other path can still ensure basic lubrication of the corresponding side of the slideway, significantly reducing the risk of coal charging plate deviation due to a single-point failure. Secondly, by setting a first lubrication oil hole at the front of the slideway and a second lubrication oil hole in the middle section, combined with the corresponding distributor, targeted oil supply to different areas of the slideway can be achieved, covering the entire operation of the coal charging plate and connecting seat. This overcomes the limitations of front-end oil supply in existing technologies, ensuring balanced lubrication of the slideway and reducing obstruction and impact caused by uneven frictional resistance, thus greatly reducing the collapse rate of coal cakes during loading. Furthermore, this system structure can automatically lubricate the slideway, which is beneficial for improving coal loading efficiency. Attached Figure Description

[0022] like Figure 1As shown, this utility model proposes a lubrication system for a coal charging device, applicable to tamping coke ovens. The lubrication system includes an oil storage tank 1, a slide 2, a first distributor 31, a second distributor 32, a first pneumatic lubrication pump 41, and a second pneumatic lubrication pump 42. The slide 2 has a first lubricating oil hole 21 and a second lubricating oil hole 22. The first lubricating oil hole 21 is connected to the first distributor 31, and the second lubricating oil hole 22 is connected to the second distributor 32. The first pneumatic lubrication pump 41 and the second pneumatic lubrication pump 42 are installed on top of the oil storage tank 1. The first pneumatic lubrication pump 41 is connected to the first distributor 31 to transport lubricating oil from the oil storage tank 1 to the first lubricating oil hole 21, and the second pneumatic lubrication pump 42 is connected to the second distributor 32 to transport lubricating oil from the oil storage tank 1 to the second lubricating oil hole 22.

[0023] In some embodiments, two slides 2 are provided, respectively installed on both sides of the bottom of the coal charging plate 3 of the coal charging device. Each slide 2 is fixed to the supporting beam 5 by bolts. The coal charging plate 3 can reciprocate between the initial position and the extreme position on the slide 2, thereby pushing the coal cake placed on it laterally into the carbonization chamber. The initial position is the starting position of the coal charging plate 3 before pushing the coal cake, usually located below the coal box or in the waiting state position connected to the coal box, at which time the coal cake has not yet started to enter the carbonization chamber. The extreme position is the end position where the coal charging plate 3 completely pushes the coal cake into the interior of the carbonization chamber, that is, the position where the coal charging plate 3 runs to the maximum stroke, usually the position where the coal cake is completely entered into the carbonization chamber and the front end of the coal charging plate 3 is aligned with the preset boundary inside the carbonization chamber. Each slide 2 is provided with a first lubricating oil hole 21 and a second lubricating oil hole 22, wherein the first lubricating oil hole 21 is located at a first preset position at the front end of the slide 2, and the second lubricating oil hole 22 is located at a second preset position in the middle of the slide 2. The front end of the coal charging plate 3 and the rear end of the connecting seat 4 in the coal charging device both have a bevel. The first lubricating oil hole 21 is located below the bevel of the coal charging plate 3 when the coal charging device is in its initial position, that is, at the first bevel. Figure 2 As shown. The second lubricating oil 22 position is selected at the bevel of the connecting seat 4 when the coal charging device is in the extreme position, that is, below the second bevel, as shown. Figure 3 As shown. This design not only ensures good lubrication throughout the entire operation of the coal charging device, but also facilitates the clearing of blocked lubrication holes, and prevents foreign objects from entering the lubrication holes at the bevel.

[0024] In some embodiments, a first pneumatic lubrication pump 41 is connected to a first distributor 31 via a first pump outlet pipeline. The first distributor 31 has two oil outlets, each connected to a first lubricating oil hole 21 on a slide plate 2 via an oil line 6. When the first pneumatic lubrication pump 41 starts working, it draws lubricating oil from the oil storage tank and delivers it to the first lubricating oil hole 21 of each slide plate 2 through the first distributor 31 to lubricate the front ends of the slide plates 2 on both sides of the bottom of the coal loading plate 3. A second pneumatic lubrication pump 42 is connected to a second distributor 32 via a second pump outlet pipeline. The second distributor 32 has two oil outlets, each connected to a second lubricating oil hole 22 on a slide plate 2 via another oil line 6. When the second pneumatic lubrication pump 42 starts working, it draws lubricating oil from the oil storage tank and delivers it to the second lubricating oil hole 22 of each slide plate 2 through the second distributor 32 to lubricate the middle parts of the slide plates 2 on both sides of the bottom of the coal loading plate 3.

[0025] According to one embodiment of the present invention, the slide lubrication system further includes a first pump outlet pipeline and a second pump outlet pipeline. The two ends of the first pump outlet pipeline are respectively connected to a first pneumatic lubrication pump 41 and a first distributor 31, and the two ends of the second pump outlet pipeline are respectively connected to a second pneumatic lubrication pump 42 and a second distributor 32.

[0026] According to one embodiment of the present invention, the slide lubrication system further includes a first valve 101 and a second valve 102. The first valve 101 is disposed on the outlet pipeline of the first pump, and the second valve 102 is disposed on the outlet pipeline of the second pump. When the first valve 101 is open, it delivers lubricating oil to the first lubricating oil hole 21 through the outlet pipeline of the first pump. When the second valve 102 is open, it delivers lubricating oil to the second lubricating oil hole 22 through the outlet pipeline of the second pump.

[0027] The first valve 101 is communicatively connected to the first pneumatic lubrication pump 41 and the first distributor 31. When the first pneumatic lubrication pump 41 and the first distributor 31 start normally, the first valve 101 is opened to deliver lubricating oil to the first lubricating oil hole 21 through the first pump outlet pipeline. When the first pneumatic lubrication pump 41 or the first distributor 31 malfunctions, the first valve 101 is closed to stop delivering lubricating oil to the first lubricating oil hole 21 through the first pump outlet pipeline.

[0028] The second valve 102 is communicatively connected to the second pneumatic lubrication pump 42 and the second distributor 32. When the second pneumatic lubrication pump 42 and the second distributor 32 start normally, the second valve 102 is opened to deliver lubricating oil to the second lubricating oil hole 22 through the outlet pipeline of the second pump. When the second pneumatic lubrication pump 42 or the second distributor 32 malfunctions, the second valve 102 is closed to stop delivering lubricating oil to the second lubricating oil hole 22 through the outlet pipeline of the second pump.

[0029] According to one embodiment of the present invention, the slide lubrication system further includes a connecting pipeline and a third valve 103 disposed on the connecting pipeline. The connecting pipeline is disposed between the first pump outlet pipeline and the second pump outlet pipeline. When the first valve 101 is closed, the third valve 103 is opened to deliver lubricating oil to the first lubricating oil hole 21 through the connecting pipeline. When the second valve 102 is closed, the third valve 103 is opened to deliver lubricating oil to the second lubricating oil hole 22 through the connecting pipeline.

[0030] In some embodiments, a first valve 101 is installed on the outlet pipeline of the first pump, and a second valve 102 is installed on the outlet pipeline of the second pump. A connecting pipeline is provided between the first valve 101 on the outlet pipeline of the first pump and the first distributor 31, and between the second valve 102 on the outlet pipeline of the second pump and the second distributor 32. A valve 103 is installed on the connecting pipeline, such as... Figure 1 As shown.

[0031] In some embodiments, if either the first pneumatic lubrication pump 41 or the first distributor 31 malfunctions, the first valve 101 is closed, and the third valve 103 is opened. When the second pneumatic lubrication pump 42 and the second distributor 32 are operating, the second valve 102 is open. If either the second pneumatic lubrication pump 42 or the second distributor 32 malfunctions, the second valve 102 is closed, and the third valve 103 is opened. When both the first valve 101 and the second valve 102 are open, the third valve 103 is closed.

[0032] In the technical solution of this utility model, through the above structural design, even if a single pneumatic lubrication pump or a distributor fails, the good lubrication state of both sides of the slide can be effectively guaranteed through the connecting pipeline, and time is created for maintenance without affecting the normal operation of the coal charging device. This greatly avoids the problem of coal cake structure cracking or even collapse due to poor lubrication of one side of the slide, reduces the coal cake collapse rate, and provides a guarantee for the smooth operation of production.

[0033] According to one embodiment of the present invention, the slide rail lubrication system further includes a first pneumatic triplet 51 and a second pneumatic triplet 52. The first pneumatic triplet 51 is connected to the first pneumatic lubrication pump 41 to output gas to the first pneumatic lubrication pump 41, and the second pneumatic triplet 52 is connected to the second pneumatic lubrication pump 42 to output gas to the second pneumatic lubrication pump 42.

[0034] According to one embodiment of the present invention, the slide rail lubrication system further includes a first air line 61 and a second air line 62. The first air line 61 is connected to a first pneumatic triplet 51 and a first pneumatic lubrication pump 41 at both ends, and the second air line 62 is connected to a second pneumatic triplet 52 and a second pneumatic lubrication pump 42 at both ends.

[0035] According to one embodiment of this utility model, the first pneumatic triplet 51 is communicatively connected to the second pneumatic lubrication pump 42. When the second pneumatic lubrication pump 42 malfunctions, the pressure of the pressure reducing valve in the first pneumatic lubrication pump 41 is increased. The second pneumatic triplet 52 is communicatively connected to the first pneumatic lubrication pump 41. When the first pneumatic lubrication pump 41 malfunctions, the pressure of the pressure reducing valve in the second pneumatic lubrication pump 42 is increased.

[0036] In some embodiments, the lubrication system of the coal charging device is started by the coal charging device itself. When the coal charging device begins operation, the solenoid valves of the first pneumatic triplet 51 and the second pneumatic triplet 52 are simultaneously energized. At this time, the first pneumatic triplet 51 outputs gas and delivers it to the first pneumatic lubrication pump 41 via the first air line 61, driving the first pneumatic lubrication pump 41 to start. Similarly, the second pneumatic triplet 52 outputs gas and delivers it to the second pneumatic lubrication pump 42 via the second air line 62, driving the second pneumatic lubrication pump 42 to start. When the coal charging operation is completed and the coal charging device returns to its initial position, the lubrication system of the coal charging device automatically stops operating, and the solenoid valves of the first and second pneumatic triplet 51 are simultaneously de-energized.

[0037] In some embodiments, when the first pneumatic lubrication pump 41 malfunctions, the first valve 101 is closed and the third valve 103 is opened. At this time, the pressure of the pressure-reducing valve in the second pneumatic triplet 52 can be increased to draw lubricating oil from the oil tank through the second pneumatic lubrication pump 42, and deliver the lubricating oil to the first distributor 31 and the second distributor 32 respectively through the second pump outlet pipeline and the connecting pipeline, ensuring that the front end and middle of the two side slide plates 2 remain lubricated. When the second pneumatic lubrication pump 42 malfunctions, the second valve 102 is closed and the third valve 103 is opened. At this time, the pressure of the pressure-reducing valve in the first pneumatic triplet 51 can be increased to draw lubricating oil from the oil tank through the first pneumatic lubrication pump 41, and deliver the lubricating oil to the first distributor 31 and the second distributor 32 respectively through the first pump outlet pipeline and the connecting pipeline, ensuring that the front end and middle of the two side slide plates 2 remain lubricated.

[0038] According to one embodiment of the present invention, the oil storage tank 1 further includes a pressure cap 11, a sliding rod 12, and a detection sensor 13. The pressure cap 11 is movably disposed inside the oil storage tank 1 and moves with the rise and fall of the lubricating oil level inside the oil storage tank 1. The first end of the sliding rod 12 is fixed to the upper surface of the pressure cap 11, and the second end extends out of the top of the oil storage tank 1 and is movably connected thereto. A sensing plate is provided at the second end, and the detection sensor 13 is disposed at the top of the oil storage tank 1.

[0039] In some embodiments, the oil reservoir 1 is equipped with a counterweighted cap 11, and a sliding rod 12 is connected to the cap 11. A sensing plate is mounted on the top of the sliding rod 12, and a detection sensor 13 is installed on the top cover of the oil reservoir 1. The main function of this structure is that when the lubricating oil in the oil reservoir 1 decreases, the cap 11 will descend with the grease and move the sliding rod 12 down together. When it descends to a preset position, the detection sensor 13 will detect the sensing plate, and then send a no-oil signal to help the driver promptly detect that the oil reservoir 1 is empty. At the same time, the counterweight function of the cap 11 can also effectively prevent the first pneumatic lubrication pump 41 and the second pneumatic lubrication pump 42 from cavitating.

[0040] According to one embodiment of the present invention, a first lubricating oil hole 21 is disposed at a first preset position of the slide rail 2, and a second lubricating oil hole 22 is disposed at a second preset position of the slide rail 2. The coal charging device reciprocates between an initial position and a limit position of the slide rail 2. When the coal charging device is in the initial position, the first bevel of the coal charging plate 3 in the coal charging device is the first preset position; when the coal charging device is in the limit position, the second bevel of the connecting seat 4 in the coal charging device is the second preset position.

[0041] According to one embodiment of the present invention, two slides 2 are symmetrically arranged on the lower surface of the coal loading plate 3, and each slide 2 is fixed to the top of a supporting beam 5. The first distributor 31 includes two first oil outlets, each of which is connected to a first lubricating oil hole 21 of a slide 2. The second distributor 32 includes two second oil outlets, each of which is connected to a second lubricating oil hole 22 of a slide 2.

[0042] In some embodiments, various possible operating conditions of the sluice lubrication system of the coal charging device are described: (1) Under normal operating conditions, when the coal charging device is started, the solenoid valves of the first pneumatic triplet 51 and the second pneumatic triplet 52 are simultaneously energized. Gas is delivered to the first pneumatic lubrication pump 41 and the second pneumatic lubrication pump 42 through the first gas pipeline 61 and the second gas pipeline 62, respectively, driving the two pneumatic lubrication pumps to start, so as to accurately deliver lubricating oil to the front end and middle of the two side slides 2 through the first pump outlet pipeline and the second pump outlet pipeline, respectively. At this time, the first valve 101 and the second valve 102 are in the open state, while the third valve 103 remains closed. At this time, the pressure of the pressure reducing valves on the first pneumatic triplet 51 and the second pneumatic triplet 52 can be adjusted to the appropriate value according to the actual lubrication state of the slide. When the coal charging operation is completed and the coal charging device is returned to the initial position, the slide lubrication system automatically stops operating, and the solenoid valves of the first pneumatic triplet 51 and the second pneumatic triplet 52 are simultaneously de-energized; (2) In the event of a malfunction of the first pneumatic lubrication pump 41, if the first pneumatic lubrication pump 41 malfunctions, close the first valve 101 and open the third valve 103. By increasing the pressure of the pressure reducing valve in the second pneumatic triplet 52, the lubrication effect at the front end of the slide rails 2 on both sides can be ensured. During this process, the first pneumatic lubrication pump 41 can be repaired or replaced at any time without interfering with the normal operation of the overall equipment. (3) In the event of a malfunction of the second pneumatic lubrication pump 42, if the second pneumatic lubrication pump 42 malfunctions, close the second valve 102 and open the third valve 103. By increasing the pressure of the pressure reducing valve in the first pneumatic triplet 51, the lubrication effect in the middle of the slides 2 on both sides can be ensured to be unaffected. Similarly, the second pneumatic lubrication pump 42 in the event of a malfunction can be repaired or replaced at any time without interrupting the overall operation of the coal charging device. (4) In the event of a malfunction in either the first distributor 31 or the second distributor 32, if the first distributor 31 malfunctions, closing the first valve 101 and simultaneously increasing the pressure of the pressure reducing valve on the second pneumatic triplet 52 can ensure the continuous and stable operation of the slide rail lubrication system. In this case, the first distributor 31 can be repaired or replaced. If the second distributor 32 malfunctions, closing the second valve 102 and simultaneously increasing the pressure of the pressure reducing valve on the first pneumatic triplet 51 can ensure the continuous and stable operation of the slide rail lubrication system. In this case, the second distributor 32 can be repaired or replaced.

[0043] In summary, the sluice lubrication system of the coal charging unit, through its scientific air circuit logic and flexible emergency response mechanism, can not only automatically start and stop the lubrication operation according to the set program, but also ensure the precise adjustment of the lubrication position through the convenient switching of on-site valves, thus ensuring that the sluice is always in a good lubrication state and providing reliable support for the stability of the coal charging process.

[0044] The lubrication system of the coal charging unit, through its scientific structural design and flexible gas path logic, can achieve the following beneficial effects: (1) By using the coal charging device to drive the pneumatic triple solenoid valve, the gas is accurately delivered to start the double pneumatic lubrication pump, which supplies oil to the front and middle of the two slides 2 respectively, covering the entire running process of the coal charging plate and the connecting seat, ensuring balanced lubrication of the slide 2, making up for the limitation of front-end oil supply in the prior art. With the standardized opening and closing of multiple valves, the pressure can be adjusted by the pressure reducing valve of the pneumatic lubrication pump, ensuring timely and appropriate lubrication during the coal charging process, and providing a stable lubrication basis for the reciprocating motion of the coal charging plate. (2) It has a complete emergency response mechanism. When either the first pneumatic lubrication pump 41 or the second pneumatic lubrication pump 42 fails, it is only necessary to close the valve on the corresponding pump outlet pipeline and open the third valve 103 on the connecting pipeline. Combined with increasing the pressure of the corresponding pneumatic triplet pressure reducing valve of the non-failed pneumatic lubrication pump, the oil supply from the other pneumatic lubrication pump can simultaneously cover the front and middle parts of both slides 2, ensuring uninterrupted lubrication. The failed pneumatic lubrication pump can be repaired and replaced at any time without affecting the overall operation of the equipment. If the distributor fails, the valve on the corresponding pump outlet pipeline can be closed for repair. At this time, the other pneumatic lubrication pump can still maintain effective lubrication of both slides 2 through pressure adjustment. It can realize the automation and precision of the lubrication process, and ensure that the slides are always in good lubrication condition through flexible emergency operation. This fundamentally reduces problems such as coal loading plate deviation and obstruction, reduces coal cake cracking and collapse rate, and significantly improves coal loading success rate and equipment operation stability.
