Description

Technical Field

[0001] The utility model relates to the field of metallurgical equipment, and particularly relates to a device for removing light and large debris by a dust collector. Background Art

[0002] For the dust collected by each dust collector, the cleanest transportation method is pipeline transportation. However, since the dust at the dust-producing point is collected by a negative pressure adsorption method, light and large debris (rags, plastic products, leaves, etc.) are also collected into the dust removal system while adsorbing and collecting the dust. After the light and large debris are adsorbed into the dust removal system, it is extremely easy to cause blockage of the dust collector and the gas ash conveying system, or affect the continuous and stable operation of the device for centrally disposing of the dust; after the dust collector, the gas ash conveying system and the device for centrally disposing of the dust are blocked, manual inspection and troubleshooting are required, which not only affects the continuous and stable operation of the system, but also increases the dust treatment cost and the labor intensity of employees. Summary of the Utility Model

[0023] It should be understood that the embodiments of the present utility model shown in the exemplary embodiments are merely illustrative. Although only a few embodiments of the present utility model have been described in detail, those skilled in the art can easily appreciate that various modifications are feasible without substantially departing from the teachings of the subject matter of the present utility model. Accordingly, all such modifications should be included within the scope of the present utility model. Without departing from the gist of the present utility model, other substitutions, modifications, variations and deletions can be made to the design, operating conditions, parameters, etc. of the following exemplary embodiments.

[0024] The present utility model provides a device for removing light and large debris by a dust collector. Please refer to Figure 1 , which includes: a debris removal device 1; a collecting pipe 2, one end of the collecting pipe 2 is connected to the side of the debris removal device 1, and the other end is connected to a dust suction hood; a debris isolator 3, the debris isolator 3 is inclined and arranged in the debris removal device 1, and a dust removal pipe 4 is opened on the side of the debris removal device 1 away from the collecting pipe 2; and a movable door 5, the movable door 5 is located opposite to the included angle formed by the collecting pipe 2 and the debris isolator 3.

[0025] The debris removal device 1 of the present utility model is installed at a suitable position between the dust suction hood and the dust collector, which is convenient for installing the debris removal device 1 and for stopping the machine to take out the intercepted large debris. Dust collector manufacturers, when building a new dust collector, design and manufacture a debris removal device that meets the needs according to the working conditions of the dust collector; customize the debris removal device 1 according to user requirements. Dust collector users can make the debris removal device 1 by themselves according to the working conditions of the dust collector. When building a new dust collector, it is integrally installed during equipment installation. For existing dust collectors that have been built and put into operation, during the system maintenance time, disconnect the dust removal pipe 4 at a suitable position in front of the existing dust collector (which is convenient for installing the debris removal device 1 and for opening the movable door of the debris removal device to take out the intercepted light and large debris during daily maintenance), and install the pre-made or purchased debris removal device on the line.

[0026] One sealed side wall of the debris removal device 1 perpendicular to the debris isolator 3 is the movable door 5. During the daily inspection and maintenance of the dust collector, the movable door can be opened to take out the debris intercepted by the grille.

[0027] The device of the present utility model is simple in technology production and operation, and the equipment and material costs to be increased are not much; for all dust collectors at all dust suction points that may suck in light and large debris, after installing the debris removal device 1, it can intercept 100% of the light and large debris that may endanger the continuous and stable operation of the dust collector, the gas ash conveying system and the dust centralized disposal device, can improve the production efficiency of the dust collector and the gas ash conveying system, reduce the production cost and the labor intensity of employees, and has remarkable economic and social benefits. It is promoted for use by all dust collector manufacturers that may suck in light and large debris.

[0028] In some embodiments, see Figure 1 One or more dampers 6 are installed at the bottom of the debris separator 3, and the installation direction of the damper 6 is consistent with the dust collection vibration direction.

[0029] When the device starts working, the air collecting pipe 2 sucks impurities into the impurity removal device 1. At this time, the debris separator 3 isolates the impurities, and finally the dust is discharged from the dust removal pipe 4; when the debris separator 3 is affected by the airflow, vibration may occur. At this time, the damper 6 is installed below the debris separator 3. Installing the damper 6 at the bottom can effectively absorb and slow down these vibrations, so that the debris separator 3 is more firmly fixed in the specified position to prevent displacement or shaking caused by vibration, thereby ensuring the continuity and efficiency of the dust collection process. Keeping the installation direction of the damper 6 consistent with the dust collection vibration direction is the key to ensuring the maximum damping effect. This design ensures that the damper 6 can directly and effectively absorb vibration energy when vibration occurs, preventing the ineffective transmission and amplification of vibration energy.

[0030] After the device is finished working, the impurities accumulated in the impurity separator 3 and the impurity removal device 1 can be taken out by opening the movable door 5.

[0031] In some embodiments, see Figure 1 The debris separator 3 is a grid, and a plurality of evenly distributed protrusions or grooves are provided on its surface.

[0032] An inclined debris separator 3 is provided in the debris removal device 1, and a plurality of evenly distributed protrusions or grooves are provided on the surface of the debris separator 3 to increase the contact area and friction with the light and large debris.

[0033] In some embodiments, see Figure 1 The debris separator 3 divides the interior of the debris removal device 1 into two independent spaces.

[0034] By dividing the interior of the impurity removal device 1 into two independent spaces, the flow and collection of dust can be controlled more effectively. One space is used for preliminary dust removal, removing larger pieces of debris through inertial separation, gravity sedimentation, etc.; the other space is used for fine dust removal, sending the dust to the dust removal pipe. The independent space design can reduce the re-dispersion of dust inside the device, thereby reducing the pollution to the working environment and equipment. At the same time, it also helps to maintain the cleanliness and work efficiency of the impurity removal device 1. The separated space makes cleaning and maintenance work easier. The two spaces can be cleaned separately without worrying about mutual interference and diffusion of dust.

[0035] In some embodiments, see Figure 1 In the two isolated independent spaces, the space connected to the air collecting pipe 2 is greater than or equal to the space connected to the dust removal pipe 4.

[0036] A larger space helps to reduce the air flow speed, making it easier for large debris to be captured or settle down, further improving the dust removal effect. One side of the dust removal pipe 4 is usually responsible for transporting the air flow containing dust to the subsequent processing equipment. The smaller space design makes the dust more evenly distributed throughout the dust removal pipe 4.

[0037] In some embodiments, refer to Figure 1 , the longitudinal cross-sectional area and the transverse cross-sectional area of the impurity removal device 1 are respectively 2-5 times the cross-sectional areas of the gas collecting pipe 2 and the dust removal pipe 4.

[0038] The overall structure is square in both the longitudinal cross-section and the transverse cross-section. The longitudinal cross-sectional area and the transverse cross-sectional area of the impurity removal device 1 are respectively 2-5 times the cross-sectional area of the gas collecting pipe 2. The cross-sectional area of the impurity removal device 1 is 2-5 times the cross-sectional area of the dust removal pipe 4. On the one hand, it is beneficial to reduce the wind speed to intercept debris, and on the other hand, it increases the storage space for the intercepted debris.

[0039] Such a setting helps the air flow to spread and mix more fully inside the impurity removal device 1, enabling dust or impurities to have a longer residence time and more opportunities to contact the debris separator 3, thereby improving the processing efficiency. When the air flow enters the impurity removal device 1, the larger space can reduce the impact and turbulence of the air flow, making the air flow flow more smoothly. This helps to reduce the impact and wear on the debris separator 3, while improving the dust removal or impurity removal effect.

[0040] In some embodiments, refer to Figure 1 , the shape of the impurity removal device 1 includes but is not limited to square, rectangular or circular.

[0041] The structural form of this device can be adapted to local conditions according to the on-site location of the dust collector. It can be square, circular, or even irregular. Without being restricted by the site, it is recommended to use a square structure, which can simplify the manufacturing process.

[0042] In some embodiments, a blowing device 7 can be provided above the debris separator 3 facing upwards to blow compressed air onto the surface of the impurity removal plate.

[0043] The blowing device 7 is arranged above the opposite side of the debris separator 3 and on the side wall of the impurity removal device 1 close to the gas collecting pipe 2, and is used to regularly blow compressed air onto the surface of the impurity removal plate to remove the fine dust and debris residues attached to the impurity removal plate, and maintain the cleanliness and impurity removal effect of the impurity removal plate.

[0044] In some embodiments, the blowing device 7 passes through the movable door 5 and is connected to a compressed air source through a pipeline.

[0045] By directly connecting to a compressed air source, the jetting device can quickly obtain a high-pressure air flow when dust cleaning is required, achieving instant response. This instantaneity ensures that the dust collector can operate continuously and efficiently without affecting the dust removal effect due to untimely dust cleaning. The high-pressure air flow provided by the compressed air source is ejected through the jetting device, capable of generating a strong pulsed air flow, causing the debris separator 3 to vibrate, thereby effectively removing the dust particles adhering to the debris separator 3. This powerful dust cleaning method can ensure the cleanliness of the debris separator 3 and extend its service life.

[0046] In some embodiments, refer to Figure 1 , the debris separator 3 is detachable.

[0047] When the debris separator 3 needs to be cleaned or replaced, due to its detachable design, the operator can quickly remove it from the system without disassembling the entire dust removal device or shutting down the machine. This greatly shortens the maintenance time and improves work efficiency.
