Abstract
Description
Technical Field
[0001] This application relates to the field of coke powder recovery technology, and in particular to a coke pusher track cleaning and dust collection device. Background Technology
[0002] The coke pusher car travels year-round on the coke side rails of the coke oven, pushing the coke produced in the coking chamber into the quenching car (or coke pot). During operation, coke dust falls onto the pusher car rails. If not cleaned up promptly, it can be blown away by the wind and pollute the surrounding environment. Furthermore, this scattered coke dust also wastes production materials. Statistics show that, for a 2×55-hole coke oven, over 10 tons of coke dust can be lost annually due to falling onto the pusher car rails, making the recovery of this dust essential. However, coking plants typically assign one worker per shift to clean up this dust, resulting in harsh working conditions and secondary dust generation that negatively impacts worker health. Moreover, coke dust embedded in the bolt gaps of the rail pressure plates is difficult to remove, making collection inconvenient for workers. Utility Model Content
[0003] This application provides a dust collection and cleaning device for coke pusher car tracks, which can replace manual labor to complete the cleaning and collection of coke powder on the coke pusher car tracks.
[0004] The above-mentioned objective of this application is achieved through the following technical solution:
[0005] A coke pusher track cleaning and dust collection device includes a dust suction hood connected to the coke pusher traveling mechanism. The dust suction hood has an avoidance channel on its lower side, and the shape of the avoidance channel on the lower side of the dust suction hood matches the shape of the coke pusher track to be cleaned.
[0006] A metal brush is fixedly installed on the lower side of the dust collection hood;
[0007] A dust collection unit is installed in the middle of the upper side of the dust collection hood. The dust collection unit can generate suction inside the dust collection hood to collect the charred powder on the lower side of the dust collection hood.
[0008] Furthermore, the length of the metal brush is equal to the length of the dust cover, and there are four metal brushes, which are symmetrically arranged along the width direction on the lower side of the dust cover.
[0009] Furthermore, two of the metal brushes are located in the clearance channel inside the dust collection hood, and the distance between the two metal brushes is equal to the width of the coke pusher track; the other two metal brushes are located at the lower ends of both sides of the dust collection hood in the width direction.
[0010] Furthermore, the dust collection unit includes a dust collection pipe and a dust collector. One end of the dust collection pipe is fixedly connected to the middle position on the upper side of the dust collection hood, and the other end of the dust collection pipe is connected to the dust collector.
[0011] Furthermore, the dust collector is a bag filter dust collector with a fan at the top.
[0012] Furthermore, a discharge device is provided at the ash hopper at the lower end of the dust collector.
[0013] Furthermore, the dust collector is installed on the operating platform on the upper part of the coke pusher.
[0014] In summary, this application includes at least one of the following beneficial technical effects:
[0015] The dust collection hood in the coke pusher track cleaning and dust collection device provided in this application is installed on the coke pusher traveling mechanism. Since the coke pusher traveling mechanism can freely reciprocate along the coke pusher track, the dust collection hood moves synchronously along the track as the traveling mechanism moves. The upper end of the dust collection hood is connected to the dust collection unit, and a metal brush is provided on the lower side of the hood. During movement along the coke pusher track, the metal brush works in conjunction with the dust collection hood to automatically clean and collect the coke powder scattered on the track and sides. Because the dust collection hood does not require a separate power unit to move along the coke pusher track, it effectively saves on operating costs. The equipment in this application not only has a simple and reasonable structure, low initial investment, environmentally friendly and energy-saving operation, and can be operated unattended, but also recovers coke powder more thoroughly. Furthermore, it greatly reduces the labor intensity of workers during the coke powder cleaning and collection process, and effectively protects the health of workers. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.
[0022] like Figures 1-3 As shown, this application discloses a coke pusher track cleaning and dust collection device, which includes a dust suction hood 1 connected to the coke pusher traveling mechanism. A clearance channel 2 is provided on the lower side of the dust suction hood 1, and the shape of the clearance channel 2 on the lower side of the dust suction hood 1 matches the shape of the coke pusher track 3 to be cleaned.
[0023] A metal brush 4 is fixedly installed on the lower side of the dust hood 1;
[0024] A dust collection unit 5 is installed in the middle of the upper side of the dust hood 1. The dust collection unit 5 can generate suction inside the dust hood 1 to collect the burnt powder on the lower side of the dust hood 1.
[0025] In the above embodiments, the coke pusher traveling mechanism, also called the coke pusher traveling device, is a power module that drives the entire steel structure of the coke pusher to move accurately on the track. The specific structure of the coke pusher and the specific principle of its movement on the track are existing technologies, and related details will not be elaborated here.
[0026] The length and width of the dust hood 1 in this application are the same as the length and width of the coke pusher track. The clearance channel 2 provided on the lower side of the dust hood 1 matches the shape of the coke pusher track 3 to be cleaned, allowing it to smoothly cover the outside of the coke pusher track 3 during use. In actual production, the cross-section of the clearance channel 2 needs to be larger than the cross-section of the coke pusher track 3, so that there is enough space in the clearance channel 2 to install the metal brush 4 for cleaning the coke pusher track 3.
[0027] The metal brush 4 of this application is composed of multiple metal brush bristles. As the dust collection hood 1 moves, the metal brush 4 uses its own flexibility to allow the coke pusher to move freely. At the same time, during the movement, the metal brush bristles can sweep out the coke powder hidden on the surface and in the gaps of the coke pusher track 3, so that the dust collection hood 1 connected to the dust collection unit 5 can collect this coke powder.
[0028] The coke pusher's traveling mechanism at the bottom of the coke pusher is connected to the dust suction hood 1 of this application. When in use, the dust suction hood 1 covers the coke pusher track 3 to be cleaned. The dust suction hood 1 moves synchronously with the coke pusher's traveling mechanism on the coke pusher track 3. The upper end of the dust suction hood 1 is connected to a dust collection unit 5. After the dust collection unit 5 is activated, it generates suction inside the dust suction hood 1 to collect coke powder on the underside of the dust suction hood 1. A metal brush 4 is provided on the lower side of the dust suction hood 1. During movement along the coke pusher track 3, the metal brush 4 works in conjunction with the dust suction hood 1 to automatically clean and collect the coke powder scattered on the coke pusher track 3 and both sides. Since the dust suction hood 1 of this application does not require a separate power unit when moving along the coke pusher track 3, it effectively saves on operating costs. The equipment proposed in this application not only has a simple and reasonable structure, low initial investment, environmentally friendly and energy-saving operation, can be operated unattended, and recovers coke powder more thoroughly, but also greatly reduces the labor intensity of workers in the process of cleaning and collecting coke powder, and the health of workers can also be effectively guaranteed.
[0029] Furthermore, such as Figure 1 and Figure 2 As shown, the length of the metal brush 4 is equal to the length of the dust cover 1, and there are four metal brushes 4. The four metal brushes 4 are symmetrically arranged on the lower side of the dust cover 1 along its width direction.
[0030] In the above embodiments, the metal brush 4 of this application is set in the manner described above, so that it can thoroughly clean the area of the coke pusher track 3 corresponding to the lower side of the dust hood 1 during the movement of the dust hood 1.
[0031] Furthermore, such as Figure 2 As shown, two metal brushes 4 are located in the clearance channel 2 inside the dust hood 1, and the distance between these two metal brushes 4 is equal to the width of the coke pusher track 3; the other two metal brushes 4 are located at the lower ends of both sides of the width direction of the dust hood 1.
[0032] In the above embodiments, the coke pusher track 3 typically includes a track section and a base section. The clearance channel 2 of this application mainly covers the outside of the track section, and its cross-section is a near-isosceles trapezoid. The two metal brushes 4 installed in the clearance channel 2 are mainly used to clean the area where coke powder easily accumulates at the junction of the track section and the base section of the coke pusher track 3. The top surface of the track section is relatively flat, and the suction power inside the dust hood 1 is sufficient to collect it. The two metal brushes 4 located at both ends of the width direction on the lower side of the dust hood 1 can be used to sweep up the coke powder outside the base section of the coke pusher track 3 when the dust hood 1 moves, so that the dust hood 1 can collect this coke powder that is farther away.
[0033] Furthermore, such as Figure 1 and Figure 3As shown, the dust collection unit 5 includes a dust collection pipe 51 and a dust collector 52. One end of the dust collection pipe 51 is fixedly connected to the middle position on the upper side of the dust collection hood 1, and the other end of the dust collection pipe 51 is connected to the dust collector 52.
[0034] In the above embodiments, the dust collection pipe 51 of this application is mainly used to connect the dust collector 52 and the dust collection hood 1. In this way, when the dust collector 52 is working, the suction force generated by it can be transmitted to the dust collection hood 1 through the dust collection pipe 51 so that the dust collection hood 1 can quickly collect the coke powder in the corresponding area below it. This process can also avoid secondary dust generation after the metal brush 4 sweeps up the coke powder.
[0035] Furthermore, such as Figure 1 and Figure 3 As shown, the dust collector 52 is a bag dust collector 52 with a fan 6 on top.
[0036] In the above embodiments, after the fan 6 at the top of the bag filter 52 is started, a negative pressure can be generated inside the equipment. When this negative pressure is transmitted to the dust collection hood 1 through the dust collection pipe 51, the dust collection hood 1 can collect the coke powder scattered on the coke pusher track 3 and both sides through suction. The dust collection pipe 51 is used to send the coke powder-containing gas collected by the dust collection hood 1 to the dust collector 52. The specific diameter of the dust collection pipe 51 is matched with the system air volume in the dust collector 52. The dust collector 52 selected in this application is a bag filter 52. The bag filter 52 is particularly suitable for filtering dust-containing gas. The filtered clean gas is discharged from the outlet of the bag filter 52, while the solid coke powder is intercepted by the surface of the bag and can fall into the ash hopper at the bottom of the bag filter 52 for temporary storage after being blown by a jet, thereby completing the collection of coke powder.
[0037] Furthermore, such as Figure 1 and Figure 3 As shown, a discharge device 7 is provided at the ash hopper at the lower end of the dust collector 52.
[0038] In the above embodiments, the unloading device 7 of this application can preferably be an electric unloader, which facilitates the periodic discharge of the coke powder recovered in the dust collector 52 into the transport vehicle. The transport vehicle can then transport the collected coke powder to the coke powder storage site.
[0039] Furthermore, such as Figure 1 and Figure 3 As shown, the dust collector 52 is installed on the operating platform on the top of the coke pusher car.
[0040] In the above embodiments, the dust collector 52 is installed on the operating platform on the upper part of the coke pusher. During the process of the coke pusher moving along the coke pusher track 3 with the dust suction hood 1, the dust collector 52 can remain relatively stationary with them. In this way, the dust collection pipe 51 between the dust collector 52 and the dust suction hood 1 can stably transport the air containing coke powder from the dust suction hood 1 to the interior of the dust collector 52.
[0041] The implementation principle of this embodiment is as follows: After the fan 6 at the top of the bag filter 52 is started, a negative pressure can be generated inside the equipment. When this negative pressure is transmitted to the dust collection hood 1 through the dust collection pipe 51, the dust collection hood 1 can collect the coke powder scattered on the coke pusher track 3 and both sides through suction. The dust collection pipe 51 is used to send the coke powder-containing gas collected by the dust collection hood 1 to the dust collector 52. The specific diameter of the dust collection pipe 51 is matched with the system air volume in the dust collector 52. The dust collector 52 used in this application is a bag filter dust collector 52. The clean gas after the dust-containing gas is filtered by the dust collector 52 is discharged from the outlet of the dust collector 52. The solid coke powder is intercepted by the surface of the filter bag and can fall into the ash hopper at the bottom of the dust collector 52 for temporary storage after being blown by a jet. The coke powder recovered by the system can be discharged into the transport vehicle periodically through the unloading device 7 on the ash hopper of the dust collector 52, and then transported to the coke powder storage yard by the transport vehicle. The dust collection hood 1 of this application is equipped with a metal brush 4 on its lower side. As the dust collection hood 1 moves along with the coke pusher, the metal brush 4, with its own flexibility, can sweep out coke powder that is difficult to directly suck up and is hidden around the coke pusher track 3. After the coke powder is swept out, the dust collection hood 1 automatically collects it. The dust collection hood 1 of this application is attached to the existing coke pusher traveling mechanism and moves along the coke pusher track 3. Therefore, no additional power device is needed during use, effectively saving on operating costs. The equipment of this application not only has a simple and reasonable structure, low initial investment, environmentally friendly and energy-saving operation, and requires no manual supervision, but also recovers coke powder more thoroughly. Furthermore, it greatly reduces the labor intensity of workers during the cleaning and collection of coke powder, and effectively protects the health of workers.
[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
