Description

Technical Field

[0001] This application relates to the field of dust removal technology, specifically a dust removal system for a dry quenching coke oven. Background Technology

[0002] Dry quenching technology, as a highly efficient and environmentally friendly coking process, has been widely used in modern steel production. However, if the dust generated during dry quenching is not effectively treated, it will have a serious impact on the environment and the health of operators. Therefore, equipping the equipment with efficient dust removal devices is particularly important.

[0003] The dust removal device for dry quenching coke ovens mainly consists of the following parts: dust collection hoods: installed on the top and sides of the dry quenching coke oven to collect the generated dust; dust collection pipelines: transporting the dust collected by the dust collection hoods to the dust removal equipment; dust removal equipment: including bag filters, electrostatic precipitators, or cyclone dust collectors, etc., used to separate and capture dust; and fans: providing the air volume required by the dust removal system to ensure that the dust can be smoothly transported to the dust removal equipment.

[0004] The fan used to provide airflow has an air inlet and an air outlet, so the fan is in a through-type shape. When the fan is not in use, external impurities will fall into the dust collector bag through the through-type fan, causing blockage of the dust collector bag. When the dust collector bag is blocked, the airflow will be not smooth. Utility Model Content

[0005] The purpose of this application is to provide a dry quenching coke oven dust removal system to solve the problem mentioned in the background art where the dust collector bag becomes clogged, resulting in insufficient gas flow.

[0006] To achieve the above objectives, this application provides the following technical solution: This utility model provides a dry quenching coke oven dust removal system, including: a dust removal box, a dust removal hood, a fan, a dust removal bag, a bonding and cleaning assembly, a vibration separation assembly, and a filter screen. The main body of the equipment consists of a dust removal box, a dust removal hood installed outside the dust removal box via a pipe, a fan installed on the top of the dust removal box, and a dust removal bag installed inside the dust removal box. The fan consists of blades on the output shaft driven by a motor. The bonding and cleaning assembly is installed on the output shaft of the fan. The bonding and cleaning assembly includes a connecting rod welded to the output shaft of the fan, a mounting plate fixed to the connecting rod, a guide rod slidably connected inside the mounting plate, an L-shaped plate welded to the bottom of the guide rod, and a No. 1 spring sleeved on the guide rod. The vibration separation assembly is installed at the bottom of the L-shaped plate, and the filter screen is welded to the fan.

[0007] By adopting the above technical solutions, the fan can be protected and effective vibration cleaning can be achieved.

[0008] Preferably, the vibration separation assembly includes a connecting shaft welded to one side of the bottom of the L-shaped plate and a fixed plate rotatably connected to the connecting shaft.

[0009] By adopting the above technical solution, the connecting shaft can provide a fixed plate to achieve changes in angle.

[0010] Preferably, the vibration separation assembly further includes a cleaning brush disposed at the bottom of the fixed plate and a second spring with its two ends welded to the outer walls of the L-shaped plate and the fixed plate, respectively.

[0011] By adopting the above technical solution, the No. 2 spring can lift the fixed plate to achieve the positioning.

[0012] Preferably, the vibration separation assembly further includes positioning holes on both sides of the bottom of the fixed plate and an L-shaped groove in the center of the bottom of the fixed plate.

[0013] By adopting the above technical solution, it is possible to provide a positioning block and an L-shaped elastic block that can be inserted into the interior.

[0014] Preferably, the vibration separation assembly further includes positioning blocks integrally formed on both sides of the top of the cleaning brush and an L-shaped elastic block integrally formed in the center of the top of the cleaning brush.

[0015] By adopting the above technical solution, the positioning block and the L-shaped elastic block can be inserted into the positioning hole and the L-shaped groove for fixation.

[0016] Preferably, the vibration separation assembly further includes a mounting rod welded to the outer wall of the fixed plate and a positioning column welded to the outer wall of the fan.

[0017] By adopting the above technical solution, the mounting rod contacts the positioning post during rotation, thereby achieving a change in angle.

[0018] In summary, this application includes at least one of the following beneficial effects:

[0019] Equipped with a bonding cleaning component, a vibration separation component, and a filter screen, the bonding cleaning component connects to a fan, allowing it to clean impurities that have fallen onto the filter screen protecting the fan without requiring additional drive equipment. Even during prolonged rotation and wear, the bonding cleaning component keeps the cleaning brush in contact with the filter screen surface. When a large amount of impurities accumulate inside the cleaning brush, the vibration separation component causes the brush to vibrate, dislodging the impurities, which are then expelled by the airflow generated by the fan.

[0020] With positioning holes, L-shaped grooves, positioning blocks, and L-shaped elastic blocks, when the cleaning brush becomes too worn and needs to be replaced, the L-shaped elastic blocks can be moved to deform inside the L-shaped grooves, which can quickly separate the cleaning brush from the fixing plate.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] The following is in conjunction with the appendix Figure 1-4 The embodiments of this application will be described in further detail. Example

[0028] Please see Figures 1-4 This embodiment provides a technical solution: a dry quenching coke oven dust removal system, including: a dust removal box 1, a dust removal hood 2, a fan 3, a dust removal bag 4, a bonding and cleaning assembly 5, a vibration separation assembly 6, and a filter screen 7;

[0029] The main body of the equipment consists of a dust collection box 1, a dust collection hood 2 installed outside the dust collection box 1 through a pipe, a fan 3 installed on the top of the dust collection box 1, and a dust collection bag 4 installed inside the dust collection box 1. The fan 3 is composed of blades on the output shaft driven by a motor. The above is the prior art and will not be described in detail below.

[0030] The bonding and cleaning assembly 5 is installed on the output shaft of the fan 3. The bonding and cleaning assembly 5 includes a connecting rod 501 welded to the output shaft of the fan 3, a mounting plate 502 fixed on the connecting rod 501, a guide rod 503 slidably connected inside the mounting plate 502, an L-shaped plate 504 welded to the bottom of the guide rod 503 and a No. 1 spring 505 sleeved on the guide rod 503. The vibration separation assembly 6 is installed at the bottom of the L-shaped plate 504, and the filter screen 7 is welded to the fan 3.

[0031] Align the dust hood 2 with the area of ​​the dry quenching coke oven that needs dust removal. At this time, start the fan 3 on the top of the dust collector 1. When the fan 3 is working, it can isolate and protect impurities through the filter screen 7. Through the cooperation of the contact cleaning component 5 and the vibration separation component 6, the filter screen 7 is cleaned by vibration. At this time, the air force generated by the fan 3 absorbs the dust on the dry quenching coke oven through the dust hood 2. When the dust is at the dust collection bag 4 of the dust collector 1, the dust collection bag 4 retains the dust on the outer wall of the dust collection bag 4, and the clean gas is discharged from the inside of the dust collector 1.

[0032] During the rotation of the fan 3, the connecting rod 501 on the fan 3 shaft can rotate synchronously. Because the connecting rod 501 is welded with the mounting plate 502, the guide rod 503 in the mounting plate 502 will push the L-shaped plate 504 vertically downward through the external spring 505. At this time, the L-shaped plate 504 will drive the vibration separation component 6 at the bottom to stick to the surface of the filter screen 7. Example

[0033] Please see Figures 1-4 This embodiment provides a technical solution: a dry quenching coke oven dust removal system, including: a vibration separation component 6;

[0034] The vibration separation assembly 6 includes a connecting shaft 601 welded to one side of the bottom of the L-shaped plate 504 and a fixing plate 602 rotatably connected to the connecting shaft 601, a cleaning brush 603 disposed at the bottom of the fixing plate 602, a second spring 604 with its two ends welded to the outer walls of the L-shaped plate 504 and the fixing plate 602 respectively, positioning holes 605 opened on both sides of the bottom of the fixing plate 602, and an L-shaped groove 606 opened at the center of the bottom of the fixing plate 602.

[0035] The positioning blocks 607 are integrally formed on both sides of the top of the cleaning brush 603, and the L-shaped elastic block 608 is integrally formed in the center of the top of the cleaning brush 603. The mounting rod 609 is welded to the outer wall of the fixing plate 602, and the positioning column 610 is welded to the outer wall of the fan 3.

[0036] When the mounting rod 609 on the fixed plate 602 contacts the positioning post 610 during rotation, the positioning post 610 drives the fixed plate 602 to change its angle through the connecting shaft 601. When the mounting rod 609 and the positioning post 610 are no longer in contact, the second spring 604 will lift the fixed plate 602 to rotate and reset, causing it to collide and vibrate with the L-shaped plate 504. At this time, the cleaning brush 603 at the bottom of the fixed plate 602 will be affected by the vibration, causing impurities to vibrate and fall off from the inside. When it is necessary to disassemble and replace the worn cleaning brush 603 periodically, the L-shaped elastic block 608 in the L-shaped groove 606 is moved so that the L-shaped elastic block 608 is no longer stuck inside the L-shaped groove 606. The cleaning brush 603 is then slid by hand. When the positioning block 607 slides out from inside the positioning hole 605, the cleaning brush 603 can be disassembled.

[0037] The implementation principle of the dry quenching coke oven dust removal system of this application is as follows:

[0038] First, align the dust hood 2 with the area of ​​the dry quenching coke oven that needs dust removal. Then, start the fan 3 on top of the dust collector 1. When the fan 3 is working, it can isolate and protect impurities through the filter screen 7. Through the cooperation of the contact cleaning component 5 and the vibration separation component 6, the filter screen 7 is cleaned by vibration. At this time, the air force generated by the fan 3 absorbs the dust on the dry quenching coke oven through the dust hood 2. When the dust is at the dust collection bag 4 of the dust collector 1, the dust collection bag 4 retains the dust on the outer wall of the dust collection bag 4, and the clean gas is discharged from the inside of the dust collector 1.

[0039] Secondly, during the rotation of the fan 3, the connecting rod 501 on the fan 3 shaft can rotate synchronously. Because the connecting rod 501 is welded with the mounting plate 502, the guide rod 503 in the mounting plate 502 will push the L-shaped plate 504 vertically downward through the external spring 505. At this time, the L-shaped plate 504 will drive the bottom vibration separation component 6 to adhere to the surface of the filter screen 7.

[0040] Finally, when the mounting rod 609 on the fixed plate 602 contacts the positioning post 610 during rotation, the positioning post 610 drives the fixed plate 602 to change its angle through the connecting shaft 601. When the mounting rod 609 and the positioning post 610 are no longer in contact, the second spring 604 will lift the fixed plate 602 to rotate and reset, causing it to collide and vibrate with the L-shaped plate 504. At this time, the cleaning brush 603 at the bottom of the fixed plate 602 will be affected by the vibration, causing impurities to vibrate and fall off from the inside. When it is necessary to periodically disassemble and replace the worn cleaning brush 603, the L-shaped elastic block 608 in the L-shaped groove 606 is moved so that the L-shaped elastic block 608 is no longer stuck inside the L-shaped groove 606. The cleaning brush 603 is then slid by hand. When the positioning block 607 slides out from inside the positioning hole 605, the cleaning brush 603 can be disassembled.

[0041] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
