Description

Technical Field

[0001] The present invention relates to the technical field of dust removal of a coke placing platform, and more specifically, to a swing coke placing system of a coal coke bin transfer station and a use method thereof. Background Art

[0002] At present, when the industry unloads coke, it is often carried out in an open space. The locomotive container is open and far away from the coke bin. When the coke bin of the transfer station is unloaded, the open area of ​​the transfer station is affected by the natural environment, causing dusty gas and dust smoke to permeate around the transfer station, and it is impossible to ensure that the operators can observe the coke level and leveling operation in time. The locomotive container is often not full, and even overfilled and overflowed, spilling onto the locomotive track and affecting normal production. At the same time, the dusty gas and dust smoke affect the environment and the health of the operators, and the overfilled coke overflows and causes unnecessary waste. How to improve the coke discharge environment so that it is more conducive to the operators to judge the amount of coke discharge is of great significance to production practice.

[0003] In the prior art, there is a fully enclosed coke placing platform disclosed, with a smoke dust collection device arranged above the coke placing platform, and a smoke dust treatment device arranged below the coke placing platform. The coke placing platform can be enclosed to prevent the unorganized emission of smoke dust; the smoke dust is enclosed in the entire coke transportation line, avoiding pollution to the working environment of the workers; however, in practice, merely enclosing the coke placing platform only prevents the smoke dust from overflowing, but cannot fundamentally reduce the generation of smoke dust, and there is still much room for improvement. Summary of the invention

[0004] 1. Technical problem to be solved by the invention

[0005] The purpose of the present invention is to overcome the problem in the prior art that when discharging coke from a coal coke silo, large amounts of smoke and dust are generated, which affects the working environment. A swinging coke discharging system for a coal coke silo transfer station and a method of using the system are provided. The device can effectively reduce smoke and dust during discharging, improve the working environment, and avoid waste caused by operators being unable to judge the amount of coke to be discharged due to the diffuse smoke and dust.

[0006] 2. Technical solution

[0007] In order to achieve the above object, the technical solution provided by the present invention is:

[0008] A swinging coke discharge system for a coal coke silo transfer station of the present invention comprises a swinging chute, which is installed below the outlet of the coke silo, one end of the swinging chute is a mounting end for movably installing the swinging chute, and the other end of the swinging chute is a swinging end, which is connected to a driving component, and the driving component is used to drive the swinging end of the swinging chute to rise and fall in the height direction; the swinging chute is used to receive the coke discharged from the outlet of the coke silo and transfer the coke from the swinging end to a locomotive container.

[0009] Furthermore, it also includes a coke release detection element, which is used to detect the level of coke delivered to the locomotive container when releasing coke.

[0010] Furthermore, the defocus detection element may be a video information acquisition element or an infrared detection element.

[0011] Furthermore, the defocusing detection element is electrically connected to the driving assembly, and the start and stop of the driving assembly is controlled according to the detection information of the defocusing detection element.

[0012] Furthermore, it also includes a coking unit, which is arranged on the entry and exit path of the locomotive container. The coking unit includes a coking scraper, which is connected to the lifting power and driven by the lifting power to perform height lifting.

[0013] Furthermore, the par-focus unit also includes a par-focus detection element, which is electrically connected to the lifting power and is used to control the start and stop of the lifting power.

[0014] Furthermore, it also includes a closed cover arranged outside the coke bin, a coke placing space is formed inside the closed cover, and a passage for a locomotive container to enter is provided at the bottom of the closed cover.

[0015] Furthermore, the flat-focus unit is arranged outside the enclosure and above the inlet and outlet path of the locomotive container.

[0016] The present invention provides a method for using a swinging coke placing system for a coal coke silo transfer station. The swinging coke placing system for a coal coke silo transfer station as described above is adopted. When the locomotive container reaches below the coke silo outlet, the driving component drives the swinging end of the swinging chute to descend downward, so that the swinging chute extends in an inclined state between the coke silo outlet and the locomotive container loading area. The coke silo starts to discharge, and the coke is gradually transported downward from the swinging chute to the locomotive container. After the loading is completed, the driving component drives the swinging end of the swinging chute to rise back upward, and the locomotive container drives away.

[0017] Furthermore, after the locomotive container leaves the coke bin exit position and arrives under the coke leveling unit, the lifting power drives the coke leveling scraper to descend, so that the coke leveling scraper falls to the material surface that can contact the locomotive container, and the material surface is flattened as the locomotive container moves. After the locomotive container leaves, the lifting power drives the coke leveling scraper to rise and reset.

[0018] 3. Beneficial effects

[0019] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0020] (1) The swinging coke releasing system of the present invention utilizes a swinging chute that can be raised and lowered to realize a transition connection between the coke releasing gate and the locomotive container, thereby reducing the material drop distance between the coke releasing gate and the locomotive container. This can significantly reduce the amount of smoke and dust generated during coke releasing, solve the problem of the locomotive container being not fully loaded with coke, and avoid the problem of the locomotive container being overloaded and overflowing, spilling onto the locomotive track, affecting normal production and the environment, thereby reducing unnecessary waste.

[0021] (2) The swing coke release system of the present invention is provided with a coke leveling unit on the entry and exit path of the locomotive container. The coke leveling scraper can be used to level the material level in the locomotive container, thereby further compacting the material and helping to avoid coke spilling or dust generation.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0031] The present invention will be further described below in conjunction with the embodiments.

[0032] Example 1

[0033] Combination Figure 1-Figure 4 A swinging coke discharge system of a coal coke silo transfer station of the present embodiment includes a swinging chute 300, which is installed below the outlet of the coke silo 200. One end of the swinging chute 300 is a mounting end for movably installing the swinging chute 300, and the other end of the swinging chute 300 is a swinging end, which is connected to a driving component 301. The driving component 301 is used to drive the swinging end of the swinging chute 300 to rise and fall in the height direction; the swinging chute 300 is used to receive the coke discharged from the outlet of the coke silo 200 and transfer the coke from the swinging end to the locomotive container 500.

[0034] In practice, the outlet of the coke bin 200 will be provided with a coke release gate, and a locomotive track 101 will be provided along the locomotive transportation path. The locomotive is provided with a locomotive container 500 for loading. Figure 1 As shown, the present design adds a swing chute 300 as a channel for material carrying and transfer. When in use, the swing chute 300 extends obliquely, with the high end being the installation end and the bottom end being the swing end, thereby realizing a transition connection between the coke release gate and the locomotive container 500, reducing the material drop distance between the coke release gate and the locomotive container 500, and significantly reducing the amount of smoke generated during coke release. When the locomotive head passes through the swing chute 300, the swing chute 300 is in a high position, and when the locomotive container 500 is in the coke release position, the swing chute 300 is in a low position for coke release, and coke release stops when the coke release height reaches the lowest point of the swing chute 300. The swing angle of the swing chute 300 is optimized according to the size of the locomotive container 500, the stacking angle of coke and the repose angle of the swing chute 300, which ensures smooth coke flow in the chute and prevents coke accumulation. At the same time, the effective volume of the locomotive container 500 is fully utilized to prevent coke from overflowing from the container during coke leveling, thereby solving the problem of the locomotive container 500 being not fully loaded with coke, and also avoiding the problem of coke being overfilled and overflowing, spilling onto the locomotive track 101, affecting normal production and the environment, thereby reducing unnecessary waste.

[0035] In some embodiments, the driving assembly 301 may be an electric hoist, and the electric hoist is used to drive the swing end of the swing chute 300 to swing up and down. The electric hoist drives the swing end of the swing chute 300 to rise to a high position so that the locomotive head can pass smoothly. When releasing the coke, the electric hoist is lowered to drive the swing end of the swing chute 300 to a low position for releasing the coke. The installation end of the swing chute 300 can be fixedly installed on the support beam or other structures on site by an articulated installation method, such as Figure 1 As shown, a support beam is provided below the coke bin 200, and the mounting end of the swing chute 300 and the driving assembly 301 can be mounted on the support beam.

[0036] Since the setting of the swing chute 300 can reduce the height of direct material dropping, thereby significantly reducing the amount of smoke and dust generated, the operator can directly observe the amount of material dropping more accurately and precisely control the timing of coke release. It can be further optimized that, in some embodiments, it also includes a coke release detection element 302, which is used to detect the coke level delivered to the locomotive container 500 when releasing coke. The specific coke release detection element 302 can adopt a video information acquisition element or an infrared detection element. And the coke release detection element 302 is electrically connected to the drive component 301, and the start and stop of the drive component 301 is controlled according to the detection information of the coke release detection element 302, thereby controlling the swing position of the swing chute 300, and can be interlocked with the coke release system of the transfer station coke bin to achieve automatic control, and timely transmit the signal to the locomotive to move the locomotive container 500. For example, the coke release detection element 302 uses a camera element to take a real-time picture of the material level in the locomotive container 500, and the operator intuitively judges the material drop situation based on the feedback of the shooting picture. When the coke release amount reaches a certain amount, the coke release gate on the coke bin 200 is controlled to close, stop coke release, and then control the drive component 301 to lift and reset the swing chute 300. If the coke release detection element 302 uses an infrared signal detection element, when the material level in the locomotive container 500 reaches a certain height, a signal is triggered to control the coke release gate on the coke bin 200 to close, stop coke release, and then control the drive component 301 to lift and reset the swing chute 300. In practice, a variety of implementation methods can be used to automatically detect the coke release amount to achieve interlocking control of the drive component 301. This is a mature technology and will not be described in detail.

[0037] After the coke is released, the locomotive needs to leave, and the highest point of the material level in the locomotive container 500 is generally higher than the outside of the carriage in a cone shape. In some embodiments, it can be further optimized to set a coke leveling unit 400 on the entry and exit path of the locomotive container 500. The coke leveling unit 400 includes a coke leveling scraper 404, which is connected to the lifting power 403 and driven by the lifting power 403 to move up and down. The coke leveling scraper 404 can be used to level the material level in the locomotive container 500, further compact the material, and also help to avoid coke spilling or dust generation.

[0038] In practice, for example, connected fixed frames 402 are provided on both sides and above the entry and exit path of the locomotive container 500, and the locomotive passes under the fixed frames 402. The lifting power 403 is installed on the fixed frames 402. The specific lifting power 403 can also be an electric hoist. The coking scraper 404 is lifted and lowered between the fixed frames 402 on both sides. Preferably, guide components are provided between the two ends of the coking scraper 404 and the fixed frames 402 on both sides, such as a guide groove is provided on the fixed frame 402 in the height direction, and the two ends of the coking scraper 404 are correspondingly slidably matched with the guide groove, etc., to ensure the stability of the lifting and lowering of the coking scraper 404.

[0039] Similarly, in order to realize the automatic control of the flattening scraper 404, the flattening unit 400 further includes a flattening detection element 401, which is electrically connected to the lifting power 403, and is used to control the start and stop of the lifting power 403, thereby controlling the height of the flattening scraper 404. It can also be interlocked with the coke storage system of the transfer station, and timely send a signal to the locomotive to move, thereby realizing automatic control. Similarly, the flattening detection element 401 can be a video information acquisition element or an infrared detection element. When the flattening scraper 404 is in a high position, the locomotive head can pass smoothly. When the flattening scraper 404 is in a low position, the movement of the locomotive is used to scrape the coke in the locomotive container 500 flat to complete the flattening function. When the locomotive passes before loading, the flattening scraper 404 is in a high position. When the locomotive passes with full materials, the flattening scraper 404 descends to flatten the coke.

[0040] In order to further optimize the working environment and prevent smoke and dust from escaping, in some embodiments, the coke bin 200 is further covered with a closed cover 100, and a coke placing space is formed inside the closed cover 100. The closed cover 100 is not a completely closed space, but has a passage for the locomotive container 500 to enter and exit. The coke flat unit 400 is arranged outside the closed cover 100 and is located above the entry and exit path of the locomotive container 500. Figure 1 As shown, the swing chute 300 and the coke bin 200 are both located inside the closed cover 100, and the locomotive container 500 for releasing coke is also located inside the closed cover 100, thereby preventing a small amount of smoke and dust from further diffusing into the open area of ​​the transfer station and affecting the natural environment around the transfer station, thereby meeting environmental protection requirements.

[0041] The present embodiment also provides a method for using the above-mentioned swinging coke leveling system for coal coke silo transfer station. When the locomotive container 500 reaches below the exit position of the coke silo 200, the driving component 301 drives the swinging end of the swinging chute 300 to drop downward, so that the swinging chute 300 extends in an inclined state between the exit of the coke silo 200 and the loading area of ​​the locomotive container 500. The coke silo 200 starts to discharge, and the coke is gradually transported downward from the swinging chute 300 to the locomotive container 500. After the loading is completed, the driving component 301 drives the swinging end of the swinging chute 300 to rise back upward, and the locomotive container 500 drives away. Furthermore, when a coke leveling unit 400 is provided, after the locomotive container 500 leaves the exit position of the coke bin 200 and arrives under the coke leveling unit 400, the lifting power 403 drives the coke leveling scraper 404 to descend, so that the coke leveling scraper 404 falls to a material surface that can contact the locomotive container 500, and the material surface is flattened as the locomotive container 500 travels. After the locomotive container 500 leaves, the lifting power 403 drives the coke leveling scraper 404 to rise and reset.

[0042] This embodiment adopts a swinging coke release method, and optimizes the design to reduce the drop distance from the coke release gate to the locomotive container 500, optimizes and reduces the amount of smoke and dust generated during coke release, reduces the requirements for the modification of dust removal technology, and saves and reduces the modification investment cost. Secondly, the coke filling rate of the locomotive container 500 is improved, and the phenomenon of the locomotive container 500 being not fully loaded or overfilled and overflowing is reduced, which reduces waste and improves the efficiency of the shipment, production and transportation of the locomotive container 500. A coke leveling unit 400 is further provided to perform coke leveling and compacting operations to avoid excessive material level and further dust generation. In addition, the coke release detection element 302 and the coke leveling detection element 401 can be further used to cooperate to ensure the coke release and coke leveling process requirements of the transfer station, realize the automation of coke release and coke leveling, and reduce the labor intensity of operators; and it can be interlocked with the coke release system of the coke silo of the transfer station to realize the intelligent operation of coke release and coke leveling, and realize unmanned operation.

[0043] The above is a schematic description of the present invention and its implementation mode, which is not restrictive and is only one of the implementation modes of the present invention, and is not actually limited thereto. Therefore, if a person skilled in the art is inspired by it and, without departing from the purpose of the invention, designs a structure and an implementation mode similar to the technical solution without creativity, they shall all fall within the protection scope of the present invention.
