Description

Technical Field

[0001] The present application relates to the technical field of blue coke production, and in particular to a coke transport, sealing and gas collecting device. Background Art

[0002] Semi-coke is made by burning clean coal. As a new type of carbon material, it has the characteristics of high fixed carbon, high specific resistivity, high chemical activity, low ash content, low aluminum, low sulfur and low phosphorus. It is gradually replacing metallurgical coke and is widely used in the production of calcium carbide, ferroalloy, ferrosilicon, silicon carbide and other products, becoming an irreplaceable carbon material. Semi-coke can replace coke (metallurgical coke) and is widely used in chemical, smelting, gasification and other industries.

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application is clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present application.

[0034] refer to Figures 1 to 6 , coke transport sealing and gas collecting device, comprising:

[0035] The support frame 100 is provided with a coke conveying assembly 101 for conveying the coke from the coke discharge system 200 to the coke screening system 300; wherein the inlet end of the coke conveying assembly 101 is connected to the outlet of the coke discharge system 200, and the outlet end of the coke conveying assembly 101 is connected to the inlet end of the coke screening system 300. The coke conveying assembly 101 may be a belt conveyor.

[0036] The sealing cover 400 is arranged on the support frame 100 to seal the coke transport assembly 101, and its two ends along its own length direction are respectively connected with the coke discharge system 200 and the coke screening system 300; wherein, the material, size, etc. of the sealing cover 400 can be set according to actual needs, the purpose is to ensure that the coke transport process is in a closed state, to prevent the unorganized waste gas pollutants generated in the coke transport process from escaping into the atmosphere and causing pollution to the environment.

[0037] The gas collecting hood 500 is connected to the top of the sealing hood 400 and the end of the gas collecting hood 500 away from the sealing hood 400 is connected to the gas collecting pipe 601 through the dust removal device 600. The end of the gas collecting pipe 601 away from the dust removal device 600 is used to connect to the coke transport waste gas treatment system 6011. The gas collecting pipe 601 is provided with an induced draft fan 6012. Under the gravitational effect of the induced draft fan 6012, the unorganized waste gas pollutants generated in the coke transport process in the sealing hood 400 enter the coke transport waste gas treatment system 6011 through the gas collecting hood 500, the dust removal device 600, and the gas collecting pipe 601 in sequence, thereby realizing the collection and treatment of the unorganized waste gas pollutants generated in the coke transport process.

[0038] During actual use of the coke transport sealed gas collection device provided in the present application, a sealing cover 400 is arranged on the support frame 100 to seal the coke transport component 101, so that the entire transportation process of transporting the coke from the coke discharge system 200 to the coke screening system 300 through the coke transport component 101 is in a sealed state, thereby preventing a large amount of unorganized waste gas pollutants (particulate matter, volatile organic matter, ammonia, hydrogen sulfide, carbon monoxide, etc.) from escaping into the atmosphere during the coke transport process, thereby avoiding the pollution of the environment by the unorganized waste gas. In addition, by connecting the air collecting hood 500 at the top of the sealing hood 400, under the suction of the induced draft fan 6012, the unorganized waste gas generated in the coking process in the air collecting hood 500 enters the dust removal device 600, and the unorganized waste gas after dust removal by the dust removal device 600 enters the coking waste gas treatment system 6011 through the air collecting pipe 601. The unorganized waste gas pollutants collected in the coking process are treated by the coking waste gas treatment system 6011, thereby realizing the collection and treatment of waste gas in the coking process, avoiding the pollution to the environment caused by direct discharge of the unorganized waste gas generated in the coking process, and making the coking process more green.

[0039] In some embodiments, reference Figure 2 The gas collecting hood 500 in the present application is trumpet-shaped; specifically, the large mouth end and the small mouth end of the gas collecting hood 500 are respectively connected to the sealing hood 400 and the dust removal device 600, so that the unorganized exhaust gas generated in the coke transport process in the sealing hood 400 is quickly drawn into the gas collecting hood 500, thereby improving the efficiency of collecting the flue gas in the coke transport process.

[0040] In some embodiments, reference Figure 2 , Figure 3 and Figure 4The dust removal device 600 in the present application includes a dust removal pipe 602 and a dust removal frame 603; specifically, the two ends of the dust removal pipe 602 are respectively connected to the top of the gas collecting hood 500 and the end of the gas collecting pipe 601 away from the coke transport waste gas treatment system 6011, and the dust removal pipe 602 is connected with a hollow connecting plate 6021 perpendicular to it, and a through hole 6022 is provided on the side of the hollow connecting plate 6021 relative to the dust removal pipe 602, and a filter screen 6031 matching the inner diameter of the dust removal pipe 602 is arranged in the dust removal frame 603, and one side of the dust removal frame 603 extends into the dust removal pipe 602 from the through hole 6022. Among them, the filter screen 6031 can be made of stainless steel, and the aperture size of the filter hole on the filter screen 6031 can be set according to the particle size of the particulate matter in the actual flue gas to be filtered, so this application does not make specific restrictions on it here. The dust removal frame 603 can be sealed and connected to the through hole 6022 by a sealing ring or the like.

[0041] In the above embodiment, both ends of the dust removal pipe 602 are connected to the top of the gas collecting hood 500 and the end of the gas collecting pipe 601 away from the coke transport waste gas treatment system 6011 through flanges, and this connection method is convenient for the installation and removal of the dust removal pipe 602. The filter 6031 is fixed by the dust removal frame 603, and the filter 6031 can be inserted into the dust removal pipe 602 or pulled out from the dust removal pipe 602 by pushing the dust removal frame 603 into the through hole 6022 or pulling it out from the through hole 6022, so that the filter 6031 can be replaced or cleaned.

[0042] In some embodiments, reference Figure 5 The dust removal frame 603 in the present application is an arched door structure; the arc section of the dust removal frame 603 matches the inner wall of the dust removal pipe 602, so as to ensure that the filter net 6031 in the dust removal frame 603 can filter the solid particles in the unorganized exhaust gas in the dust removal pipe 602.

[0043] Specifically, a fixing groove matching the side of the dust removal frame 603 located therein is provided on the inner wall of the dust removal pipe 602 (wherein the wall of the dust removal pipe 602 has a preset thickness, and the preset thickness can ensure that the fixing groove is provided on the inner wall of the dust removal pipe 602), and a handle 6032 is provided on the side of the dust removal frame 603 away from the dust removal pipe 602. One side of the arc-shaped end of the dust removal frame 603 is embedded in the fixing groove, which improves the stability of the dust removal frame 603 in the fixing groove, and the handle 6032 facilitates the dust removal frame 603 to be pushed into the through hole 6022, or pulled out from the through hole 6022, which improves the convenience of the dust removal frame 603 entering and exiting the dust removal pipe 602.

[0044] In some embodiments, reference Figure 3The bottom of the sealing cover 400 in the present application is at a preset distance from the top surface of the focus delivery assembly 101 (which can be set according to actual needs and is not specifically limited here). This avoids the bottom end of the sealing cover 400 from abutting against the focus delivery assembly 101, thereby ensuring the normal focus delivery process of the focus delivery assembly 101.

[0045] Specifically, the bottom of the sealing cover 400 is connected to the top surface of the focus transport component 101 through a rubber 401 made of a flexible and sealed material (since the rubber 401 is made of a flexible and sealed material, that is, the rubber 401 has the ability to deform, so when the bottom of the rubber 401 contacts the top surface of the focus transport component 101, the focus transport component 101 can easily overcome the friction between the bottom of the rubber 401 and its own top surface during the transportation process, thereby ensuring that the focus transport process of the focus transport component 101 can proceed smoothly), and the height of the rubber 401 is greater than the preset distance, so that the rubber 401 can seal the space between the focus transport component 101 and the sealing cover 400, and the setting of the induced draft fan 6012 enables the unorganized exhaust gas in the space between the focus transport component 101 and the sealing cover 400 to be drawn upward.

[0046] In some embodiments, reference Figure 2 and Figure 3 The sealing cover 400 in the present application includes a plurality of sealing units 402, a first connecting plate 403 and a second connecting plate 404; specifically, the heights of the plurality of sealing units 402 decrease successively along the direction in which the coke conveying assembly 101 conveys coke, and each sealing unit 402 includes a sealing rear plate 4021, a sealing top plate 4022 and a sealing front plate 4023; specifically, the bottoms of the sealing rear plate 4021 and the sealing front plate 4023 are connected to the top surface of the coke conveying assembly 101 through the rubber 401, and the opposite sides of the sealing top plate 4022 are respectively hinged and clamped to the sealing rear plate 4021 and the sealing front plate 4023, so that it is easy to open the sealing top plate 4022, making the maintenance and inspection process of the coke conveying assembly 101 more convenient.

[0047] In addition, the first connecting plate 403 and the second connecting plate 404 are respectively connected to the coke discharge system 200 and the coke screening system 300 through the conveying pipe 4031. The first connecting plate 403 and the second connecting plate 404 are used to seal the two sides of the sealing cover 400 along the length direction of the coke conveying assembly 101, so that the coke conveying process of the coke conveying assembly 101 is in a sealed state, and the unorganized waste gas generated during the coke conveying process is prevented from escaping into the atmosphere as much as possible.

[0048] In some embodiments, reference Figure 3In the present application, each two adjacent sealing top plates 4022 are arranged up and down and connected by a fastener 700, and a sealing strip 800 is arranged in the gap between the two. The fastener 700 is a fastening bolt, and the two sealing top plates 4022 arranged up and down are provided with threaded through holes matching the fastening bolts (the size of the sealing unit 402 corresponding to the upper sealing top plate 4022 is larger than the size of the sealing unit 402 corresponding to the lower sealing top plate 4022, one side of the lower sealing unit 402 extends into one side of the upper sealing unit 402, and the sealing top plate 4022 of the upper sealing unit 402 is connected to the sealing top plate 4022 of the lower sealing unit 402 by the fastener 700, and the outer wall of the sealing front plate 4023 and the outer wall of the sealing rear plate 4021 of the lower sealing unit 402 are respectively connected to the upper sealing unit 402). The inner wall of the sealing front plate 4023 and the inner wall of the sealing rear plate 4021 in element 402 are tightly attached), the screw ends of the fastening bolts are successively penetrated through the threaded through holes of the upper sealing top plate 4022 and the threaded through holes of the lower sealing top plate 4022, thereby successively realizing the connection between the two upper and lower sealing top plates 4022. The upper and lower sealing top plates 4022 are fixed by the fastening bolts, so that the upper and lower sealing top plates 4022 are easy to disassemble. After disassembly, the focus transport assembly 101 can be maintained or repaired, and the setting of the sealing strip 800 can seal the gap between the upper and lower sealing top plates 4022, so that the entire focus transport process is in a sealed state. In order to ensure the sealing performance between two adjacent sealing units 402, a sealing strip 800 can be set between the sealing front plate 4023 of the upper sealing unit 402 and the sealing front plate 4023 of the lower sealing unit 402 and between the sealing rear plate 4021 of the upper sealing unit 402 and the sealing rear plate 4021 of the lower sealing unit 402.

[0049] In some embodiments, reference Figure 3 In the present application, a buckle 900 is provided on the sealing top plate 4022 , and a slot 1000 is provided on the sealing front plate 4023 ; or, a slot 1000 is provided on the sealing top plate 4022 , and a buckle 900 is provided on the sealing front plate 4023 .

[0050] In the above embodiment, the connection between the sealing top plate 4022 and the sealing front plate 4023 is achieved by snapping the buckle 900 on the sealing top plate 4022 into the slot 1000 on the sealing front plate 4023 or snapping the buckle 900 on the sealing front plate 4023 into the slot 1000 on the sealing top plate 4022. The above connection method between the two is easy to operate and facilitates the separation of the sealing top plate 4022 from the sealing front plate 4023, making the opening operation of the sealing top plate 4022 more convenient.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
