Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors, and in particular to a dust collector pretreatment device and a dust collector. Background Art

[0002] A dust collector is a device that separates dust from gas. For example, the more commonly used wet dust collector combines the water bath and spraying methods into one. First, the dust-containing gas is pressed into a water tank filled with water at a certain height using the suction force of a high-pressure centrifugal fan. The water bath will adsorb some of the dust in the water. After evenly distributed and diverted, the gas flows from bottom to top, while the high-pressure nozzle sprays water mist from top to bottom to capture the remaining dust particles, thus performing dust removal.

[0003] However, in actual use, when the existing dust collectors encounter high dust content or there are many impurities in the gas, such as dust removal operations inside steel plants, the gas is directly transported to the dust collector through the intake pipe, such as inside a wet dust collector. After water bath dust removal, and when the gas floats from bottom to top, the gas will still contain a large amount of dust or impurities. At this time, the water mist sprayed by the high-pressure nozzle may not be able to effectively remove all dust or impurities, affecting the dust removal effect. Utility Model Content

[0029] To solve the above technical problems, Figure 1 and 2 As shown, an embodiment of the utility model provides a dust collector pretreatment device, including an air intake pipe 2 and a pretreatment mechanism 3, the pretreatment mechanism 3 including a sleeve 301, a filter cover 302 and a collection box 309, the air intake pipe 2 is segmented into an upper section and a lower section corresponding to the positions, one end of the upper section of the air intake pipe 2 is used to be connected to the dust collector body 1, the filter cover 302 is connected to the other end of the upper section of the air intake pipe 2, the sleeve 301 is sleeved on the segment of the air intake pipe 2, the upper end of the sleeve 301 is sealed to the outer wall of the upper section of the air intake pipe 2, the lower end of the sleeve 301 is sealed to the outer wall of the lower section of the air intake pipe 2, the upper end of the collection box 309 is an open structure, and the side wall of the bottom of the sleeve 301 is provided with a notch matched with the collection box 309, the collection box 309 is used to be connected to the sleeve 301 in a drawer-like manner through the notch.

[0030] It should be noted that the dust collector body 1 is, for example, a wet dust collector, and is internally provided with conventional dust removal devices such as a water bath and a spraying device, which will not be described in detail here. The air intake pipe 2 is divided into an upper section and a lower section, that is, the air intake pipe 2 is disconnected and provided for providing a filter cover 302 and collecting dust and impurities, such as Figure 2As shown in the figure, the upper section of the air intake pipe 2 is located at the top, and the lower section of the air intake pipe 2 is located at the bottom. The positions of the two correspond to each other, which means that they are coaxially arranged, which is more conducive to the airflow flowing into the dust collector body 1, and is more conducive to setting a filter cover 302 at the lower end of the upper section of the air intake pipe 2. The filter cover 302 completely covers the lower end of the upper section of the air intake pipe 2. The mesh size and density of the filter cover 302 are set according to actual needs, and at least part of the dust and impurities can be filtered out. At the same time, the air intake power mechanism, such as a high-pressure centrifugal fan, can be connected to the upper section or to the lower section. As long as the airflow is from bottom to top, that is, from the lower section to the upper section and then enters the interior of the dust collector body 1, no specific limitation is made here. In addition, the upper and lower ends of the sleeve 301 may be provided with, for example, circular holes for socketing with the air intake pipe 2. The upper and lower ends of the sleeve 301 and the upper and lower sections of the air intake pipe 2 may be sealed respectively by connection structures such as welding, glue sealing or sealing rings. As long as a closed cavity is formed in the sleeve 301, no specific limitation is made here.

[0031] Specifically, the sleeve 301 is a cylindrical structure with a diameter greater than that of the intake pipe 2, and the notch at the bottom of the side wall is a circular arc hole. Figure 3 As shown, the overall structure of the collection box 309 is also an arc-shaped structure, and its drawer-like connection with the notch is that the collection box 309 is slidably connected in the notch, and when the collection box 309 is located in the sleeve 301, the outer wall of the collection box 309, that is, the outer wall away from the air intake pipe 2, fits with the outer wall of the sleeve 301 to achieve sealing. Preferably, the pretreatment mechanism 3 also includes a sealing plate 310, which is an arc-shaped plate adapted to the shape of the notch and is connected to the edge of the outer wall of the collection box 309. When the collection box 309 is located in the sleeve 301, the sealing plate 310 can be fixedly connected to the outer wall of the sleeve 309 by screws, so as to further improve the overall sealing performance and prevent dust and impurities from leaking out again to affect the surrounding environment.

[0032] In the present embodiment, the dust collector pretreatment device provided in the present embodiment, by setting an air intake pipe 2 and a pretreatment mechanism 3, the air intake pipe 2 can be connected to, for example, a fan for initial air suction for dust removal, and by setting the air intake pipe 2 into sections corresponding to the upper and lower sections, and by sleeve 301 of the pretreatment mechanism 3 being sleeved and sealed at the sections of the air intake pipe 2, that is, a closed cavity can be formed at the sections of the air intake pipe 2 through the sleeve 301, and the pretreatment operation of dust removal can be performed in the cavity, and by connecting the upper section of the air intake pipe 2 to the dust collector body 1, the gas flows from the lower section of the air intake pipe 2 to the upper section and then enters the dust collector body 1, accordingly, by setting a filter cover 302 at one end of the upper section of the air intake pipe 2 located in the sleeve 301, the gas to be dusted sucked in by the air intake pipe 2 can be preliminarily filtered through the filter cover 302, and the gas can be filtered out The larger solid impurities in the dust collector are removed, which reduces the dust removal pressure inside the dust collector body 1, thereby effectively improving the dust removal effect and efficiency inside the dust collector body 1. At the same time, by opening a gap in the bottom side wall of the sleeve 301 and equipping it with a collection box 309 which is drawer-type connected to it and has an opening structure at the upper end, the dust or impurities filtered out by the filter cover 302 can fall into the bottom of the sleeve 301 and the collection box 309. After working for a period of time, or when a certain amount of filtered dust or impurities is formed, the collection box 309 can be removed from the gap of the sleeve 301 by removing the screws on the surface of the sealing plate 310 to transfer the dust or impurities for treatment. The drawer-type connected collection box 309 can also ensure the sealing of the gap, and prevent re-pollution of the surrounding environment, which is convenient to use, thereby further improving the efficiency and effect of the dust removal operation.

[0033] Alternatively, if Figure 2 As shown, the pretreatment mechanism 3 also includes a bracket, a rotating blade 306 and a cleaning brush. The bracket is connected to the inner wall of the lower section of the air intake pipe 2. The rotating blade 306 is rotatably connected to the bracket and is located in the lower section of the air intake pipe 2. The cleaning brush is connected to the upper end of the rotating blade 306, and the cleaning brush abuts against the lower surface of the filter cover 302.

[0034] Specifically, the bracket is connected to the upper end of the lower section of the air intake pipe 2, and the middle part of the rotating blade 306 is rotatably connected to the bracket. At the same time, the bracket does not affect the air intake of the air intake pipe 2. As the air intake of the air intake pipe 2, the rotating blade 306 will rotate accordingly, that is, rotate around the bracket. Of course, according to actual needs, the shape of the cleaning brush is adapted to the lower surface of the filter cover 302, so as to facilitate comprehensive cleaning of the lower surface of the filter cover 302.

[0035] In this embodiment, by connecting the bracket to the inner wall of the lower section of the air inlet pipe 2, and by rotatably connecting the rotating blades 306 to the bracket, when the dust collector is working, that is, when the air inlet pipe 2 draws air, as the air inlet pipe 2 draws air, the wind force will drive the rotating blades 306 to rotate, such as similar to a windmill, thereby driving the cleaning brush connected to the upper end of the rotating blades 306 to rotate. At the same time, by setting the cleaning brush in contact with the lower surface of the filter cover 302, when the cleaning brush rotates, the lower surface of the filter cover 302 is cleaned, and the dust or impurities attached to the lower surface of the filter cover 302 can be filtered out and scraped off, thereby preventing the filter cover 302 from being blocked and affecting the air intake efficiency, thereby effectively improving the overall dust removal efficiency and effect.

[0036] Alternatively, if Figure 2 As shown, the bracket includes a cross bar 304 and a rotating shaft 305 , the two ends of the cross bar 304 are respectively connected to the inner wall of the lower section of the intake pipe 2 , the rotating shaft 305 is vertically connected to the middle of the cross bar 304 , and the rotating blade 306 is rotatably connected to the rotating shaft 305 .

[0037] Specifically, the filter cover 302 is a hemispherical cover structure, which can completely cover the lower end of the upper section of the intake pipe 2 without affecting the air intake. Correspondingly, the cleaning brush is a semicircular rod-shaped structure as a whole, which can better and more comprehensively fit the lower surface of the filter cover 302, that is, the outer spherical surface, and the scraping effect is more thorough and effective.

[0038] In this embodiment, by setting the bracket as a structural form in which the crossbar 304 and the rotating shaft 305 are connected, the air intake efficiency is not affected. At the same time, by connecting the crossbar 304 to the inner wall of the lower section of the air inlet pipe 2, and vertically connecting the rotating shaft 305 to the middle of the crossbar 304, and by rotating the rotating blade 306 to the rotating shaft 305, when the rotating blade 306 rotates with the wind, that is, when it rotates around the rotating shaft, it is equivalent to rotating around the axis of the air inlet pipe 2, and the rotation is more stable and reliable, and then it can more effectively drive the cleaning brush to perform rotational cleaning, and the cleaning effect is better. It should be noted that the rotating blade 306 can be rotatably connected to the rotating shaft through, for example, a bearing.

[0039] Alternatively, if Figure 2 As shown, the cleaning brush includes a cleaning frame 307 and a brush 308. The lower end of the cleaning frame 307 is connected to the middle of the rotating blade 306, and the upper end of the cleaning frame 307 is adapted to the shape of the lower surface of the filter cover 302. The brush 308 is connected to the upper end of the cleaning frame 307 and abuts against the lower surface of the filter cover 302.

[0040] Specifically, the cleaning frame 307 can be a semicircular rod structure, and the middle part of the lower end can be connected to the middle part of the rotating blade 306 by a vertical rod, so that the rotating blade 306 can rotate and drive the cleaning frame to rotate coaxially. The brush 308 can be bonded to the upper end of the cleaning frame 307, that is, the whole is also semicircular, which can more comprehensively clean the lower surface of the filter cover 302, that is, the outer hemispherical surface.

[0041] In this embodiment, the cleaning brush is provided as a structural form in which the cleaning frame 307 and the brush 308 are connected, and the lower end of the cleaning frame 307 is connected to the middle part of the rotating blade 306. As the air entering the air intake pipe 2 drives the rotating blade 306 to rotate, the cleaning frame 307 can be driven to rotate coaxially. Moreover, by adapting the shape of the upper end of the cleaning frame 307 to the lower surface of the filter cover 302, the brush 308 can scrape the lower surface of the filter cover 302 more comprehensively. At the same time, the brush 308 will not cause damage to the filter cover 302, thereby increasing the service life.

[0042] Alternatively, if Figure 2 As shown, the pre-treatment mechanism 3 further includes an inclined plate 311 , which is connected to the sleeve 301 and is inclined toward the collection box 309 .

[0043] Specifically, the inclined plate 311 can be an arc plate that is adapted to the shape of the cavity formed between the sleeve 301 and the lower section of the intake pipe 2, such as a semi-circular ring plate or a partial circular ring plate. At the same time, the inclined plate 311 is inclined toward the collecting box 309, which means that the lower end of the inclined plate 311 is closer to the collecting box 309, that is, the dust and impurities falling on the inclined plate 311 will slide toward the collecting box 309, which is more conducive to the rapid collection of dust and impurities.

[0044] In this embodiment, the inclined plate 311 is tilted inside the sleeve 301, and the inclined plate 311 is tilted toward the collection box 309, so that the dust and impurities filtered out by the filter cover 302 will slide toward the collection box 309 after falling on the inclined plate 311, which is beneficial to the collection and transfer of dust and impurities.

[0045] Alternatively, if Figure 2 and Figure 3 As shown, the collecting box 309 and the inclined plate 311 are both arc-shaped structures arranged along the circumference of the intake pipe 2, and the collecting box 309 and the inclined plate 311 are projected in the axial direction of the intake pipe 2 into a circular ring shape.

[0046] Specifically, the axial projections of the collecting box 309 and the inclined plate 311 on the intake pipe 2 are both partial circular ring shapes. Preferably, the axial projections of the two on the intake pipe 2 are combined to form a complete circular ring shape, and the inner wall of the collecting box 309, that is, the wall close to the intake pipe 2, is fitted with the outer wall of the lower section of the intake pipe 2, one end of the inclined plate 311 is fitted with the inner wall of the sleeve 301, and the other end is fitted with the outer wall of the lower section of the intake pipe 2, that is, the collecting box 309 and the inclined plate 311 completely cover the axial projection of the circular cavity formed between the sleeve 301 and the lower section of the intake pipe 2 on the intake pipe 2, thereby being able to fully collect fallen dust and impurities.

[0047] In this embodiment, by setting the collecting box 309 and the inclined plate 311 as an arc structure arranged along the circumference of the intake pipe 2, and by setting the overall shape of the two to be a circular ring shape projected in the axial direction of the intake pipe 2, it is more conducive to the collection of dust and impurities. That is, after the dust and impurities fall from the lower surface of the filter cover 302 to between the sleeve 301 and the outer wall of the lower section of the intake pipe 2, the collecting box 309 and the inclined plate 311 can collect and process them more comprehensively, further improving the efficiency and effect of the dust removal operation.

[0048] Alternatively, if Figure 2 and Figure 4 As shown, a groove matched with the inclined plate 311 is provided in the sleeve 301, and the inclined plate 311 overlaps the notch of the groove. The pre-treatment mechanism also includes a vibration component 303, and the vibration component 303 is arranged inside the groove. The vibration end of the vibration component 303 is used to abut against the inclined plate 311.

[0049] Specifically, the groove can be formed by the sleeve 301 from its bottom wall upward, and bend along the outer wall of the lower section of the intake pipe 2, and be surrounded by the inner wall of the sleeve 301. One side of the groove is higher than the other side, which is more conducive to the inclined setting of the inclined plate 311.

[0050] In this embodiment, a groove compatible with the inclined plate 311 is set in the sleeve 301, and the inclined plate 311 is overlapped at its groove, and the vibration component 303 is set in the groove. When the vibration component 303 is started, the vibrating end of the vibration component 303 can abut the inclined plate 311 and drive it to vibrate, which is more conducive to the dust and impurities that fall on the inclined plate 311 to slide toward the collection box 309 with the vibration, so that the dust and impurities can be cleaned and collected more deeply.

[0051] Alternatively, if Figure 2 and Figure 4As shown, the vibration component 303 includes a shell 3031, a motor 3032, a turntable 3033, a connecting rod 3035, a movable plate 3036 and a movable rod 3037. The motor 3032 is arranged at the bottom of the shell 3031, and the motor 3032 is drivingly connected to the turntable 3033. One end of the connecting rod 3035 is hinged to the turntable 3033, and the other end is hinged to the movable plate 3036. The edge of the movable plate 3036 is slidably connected to the inner wall of the shell 3031. The lower end of the movable rod 3037 is connected to the movable plate 3036, and the upper end of the movable rod 3037 is used to abut against the inclined plate 311.

[0052] Specifically, the turntable 3033 is in the shape of a disc, and its rotation is more stable. The central opening is connected to the output shaft of the motor 3032. The turntable 3033 is vertically arranged, that is, the output shaft of the motor 3032 is horizontally arranged. At the same time, the lower end of the connecting rod 3035 is hinged to the position of the turntable other than the center through the pin 3034, which is also a rotational connection. In addition, the movable plate 3036 is horizontally arranged, and its shape is adapted to the horizontal cross-sectional shape of the internal cavity of the shell 3031, that is, when the movable plate 3036 moves up and down, it is more stable and reliable. In addition, the lower end of the movable rod 3037 is connected to the middle part of the upper surface of the movable plate 3036 and is vertically arranged, so that it moves vertically back and forth up and down, that is, the vibration action is more stable and reliable.

[0053] In this embodiment, through the above-mentioned structural setting, when in use, the motor 3032 can be started to work. Of course, it should be understood that the motor 3032 can be started and stopped by remote control, or a control line can be led out to the outside of the sleeve 301 to connect a control switch. No specific limitation is made here. The rotation of the output shaft of the motor 3032 can drive the turntable 3033 to rotate, and the rotation of the turntable 3033 drives the connecting rod 3035 to move, forming a cam mechanism-like movement. The connecting rod 3035 then drives the moving plate 3036 to move up and down. At the same time, by sliding the moving plate 3036 to the inner wall of the shell 3031, the shell 3031 can limit the moving plate 3036 to only move up and down, and the structure is more stable and reliable. The moving plate 3036 drives the moving rod 3037 to move up and down, and then the upper end of the moving rod 3037 can continuously lift and drop the inclined plate 311 to form a vibration action, which is more conducive to cleaning the dust and impurities dropped on the inclined plate 311 to the collection box 309. The structural setting is reasonable and reliable, and the operation is stable.

[0054] Alternatively, if Figure 2 and Figure 4As shown, the vibration assembly 303 also includes a vibration plate 3038, which is connected to the upper end of the moving rod 3037, and the vibration plate 3038 is set to be consistent with the tilting direction and angle of the tilting plate 311, and the vibration plate 3038 is used to abut against the tilting plate 311.

[0055] Specifically, the size of the vibration plate 3038 is smaller than that of the inclined plate 311, and its inclination direction and inclination angle are set to be consistent with those of the inclined plate 311, which means that the upper surface of the vibration plate 3038 can be fitted and abutted against the lower surface of the inclined plate 311 to form a vibration action, which is more stable and reliable. At the same time, a through hole is opened in the upper end of the shell 3031 and is adapted to the moving rod 3037 and opened in the vertical direction. The moving rod 3037 is inserted into the through hole. The through hole can form a further movement stroke limit for the moving rod 3037 to prevent it from tilting and shaking, etc., making the overall operation more stable and reliable.
