Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, specifically a negative pressure suction type dust collection device. Background Technology

[0002] With the development of industrial production and the improvement of people's environmental awareness, various dust removal technologies have been developed and various dust removal equipment have emerged. Among them, bag filters are widely used in industry to purify dust-laden gases generated in metallurgy, mining, chemical, cement, power generation, and grain processing industries.

[0003] The existing baghouse dust collectors mainly use mechanical vibration cleaning baghouse dust collectors, reverse air baghouse dust collectors, and pulse jet baghouse dust collectors. The cost of filter bags accounts for a large proportion of the entire dust collector cost, and the number of filter bags is large, making filter bag replacement extremely inconvenient. Therefore, the problem of filter bag damage is very prominent. In addition, pulse jet baghouse dust collectors require a matching bag cage for the filter, which needs to be inspected and replaced regularly, making it inconvenient to use and costly.

[0004] To overcome the above-mentioned defects, prior art 1 (Chinese patent application number CN201710213999.1, application date 2017-04-01) provides an internal filtration negative pressure dust removal device, comprising a dust removal box, a dust hopper, a dust removal chamber, and a partition structure. Each dust removal chamber is equipped with a filter bag body through a filter bag installation structure, which can vertically divide the dust removal chamber into a dust-laden gas channel and a clean gas channel. The dust-laden gas channel is located on the inner circumference of the filter bag body, and the clean gas channel is located on the outer circumference of the filter bag body. The upper circumference of the dust removal box is provided with several air inlets with air inlet valves, and the lower circumference of the dust removal box is provided with several air outlets with air outlet valves. All air outlets are connected to an induced draft fan. The lower circumference of the dust removal box is provided with several dust removal valves.

[0005] During use, the air intake pipe cannot be struck, and a large amount of dust gradually accumulates inside the air intake pipe. This dust not only occupies the internal space of the air intake pipe, but also gradually reduces the cross-sectional area for gas flow, thus affecting the working efficiency of the device.

[0006] To address the aforementioned issues, there is an urgent need for innovative design based on the existing internal filtration negative pressure dust removal device. Utility Model Content

[0007] The purpose of this utility model is to provide a negative pressure suction dust collection device to solve the problem in the above-mentioned background technology where the air inlet pipe is struck, and a large amount of dust gradually remains inside the air inlet pipe. This dust accumulates continuously, not only occupying the internal space of the air inlet pipe, but also gradually reducing the cross-sectional area for gas flow, thus affecting the working efficiency of the device.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a negative pressure suction dust collection device, comprising a box body, a box cover movably connected to the upper surface of the box body, a rotating shaft movably connected inside the box cover, an air inlet pipe fixedly connected to the left side of the box cover, and an exhaust pipe fixedly connected to the rear side of the box cover.

[0009] The upper surface of the box cover is fixedly connected to a motor, and the box cover is movably connected to a second rotating shaft. A fixing block is bolted to the left side of the box cover, and a fixing plate is fixedly connected to the lower surface of the box cover.

[0012] Also includes:

[0013] An electric motor, the output end of which is fixedly connected to the first rotating shaft, and a pulley is sleeved on the surface of the first rotating shaft, and the other end of the pulley is fixedly connected to the second rotating shaft;

[0014] A fixed block, wherein a sliding column is slidably connected inside the fixed block, and the lower surface of the sliding column is in contact with the surface of the air intake pipe.

[0015] Preferably, a turntable is fixedly connected to the upper surface of the second rotating shaft, and an upper magnet is fixedly connected to the lower surface of the turntable, with the upper magnets symmetrically distributed about the center of the lower surface of the turntable.

[0016] Preferably, a connecting plate is fixedly connected to the upper surface of the sliding column, and a lower magnet is fixedly connected to the upper surface of the connecting plate, wherein the magnetic poles on the upper surface of the lower magnet are opposite to the magnetic poles on the lower surface of the upper magnet.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: This negative pressure suction type dust collection device adopts a novel structural design, the specific details of which are as follows:

[0022] (1) In this negative pressure suction dust removal device, the second rotating shaft drives the magnet on the surface of the turntable to rotate. When the lower magnet contacts the upper magnet, the magnetic force pushes the sliding column to knock on the air inlet pipe, which reduces the dust residue inside the air inlet pipe and improves the working efficiency of the device.

[0023] Furthermore, a dust collection box is installed at the bottom of the box. The dust collection box collects dust and prevents the dust from being stirred up again and entering the purified gas.

[0024] (2) In this negative pressure suction dust collection device, the No. 2 spring effectively reduces the wear of the sliding column on the air inlet pipe, extends the working life of the device, and the No. 2 spring makes the pressure of the sliding column on the air inlet pipe evenly distributed and relieved.

[0025] Furthermore, this allows the intake pipe to maintain good working condition for a long time, while effectively reducing damage and leakage caused by excessive wear;

[0026] (3) In this negative pressure suction dust removal device, the fan slides on the connecting rod, which can more comprehensively cover the space that needs dust removal and reduce dust accumulation. At the same time, it reduces the damage to the fan components caused by stress concentration and improves the dust removal efficiency of the device. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Example 1: By configuring the connection between motor 1, second rotating shaft 4, and sliding column 13, the working efficiency of the device is improved, such as... Figures 1-3 As shown:

[0037] Includes a box body 20, with a box cover 6 movably connected to the upper surface of the box body 20, and a rotating shaft 2 movably connected inside the box cover 6. An air intake pipe 18 is fixedly connected to the left side of the box cover 6, and an exhaust pipe 19 is fixedly connected to the rear side of the box cover 6.

[0038] The upper surface of the cover 6 is fixedly connected to the motor 1, and the cover 6 is movably connected to the second rotating shaft 4. The left side of the cover 6 is bolted to the fixing block 7. The lower surface of the cover 6 is fixedly connected to the fixing plate 11. The lower surface of the cover 6 is fixedly connected to the connecting rod 12, and the surface of the connecting rod 12 is slidably connected to the fan 9. The inside of the box 20 is fixedly connected to the dust removal pipe 22, and the lower surface of the box 20 is fixedly connected to the dust collection box 21.

[0039] Also includes:

[0040] The motor 1 has a first rotating shaft 2 fixedly connected to its output end, and a pulley 3 is sleeved and connected to the surface of the first rotating shaft 2. The other end of the pulley 3 is fixedly connected to the second rotating shaft 4. The fixing block 7 has a sliding column 13 slidably connected inside the fixing block 7. The lower surface of the sliding column 13 is in contact with the surface of the air intake pipe 18.

[0041] When the device is working, the motor 1 drives the first rotating shaft 2 to rotate. The pulley 3 connects the first rotating shaft 2 and the second rotating shaft 4, causing the second rotating shaft 4 to rotate. This rotates the magnet on the surface of the turntable 5, causing the sliding column 13 to strike the air inlet pipe 18, reducing the dust residue inside the air inlet pipe 18. At the same time, a dust collection box 21 is installed at the lower end of the housing 20. The dust collection box 21 collects dust and prevents dust from being stirred up again and entering the purified gas, thus improving the working efficiency of the device.

[0042] Example 2: In this example, the difference from Example 1 is that... Figures 4-5 As shown:

[0043] A turntable 5 is fixedly connected to the upper surface of the second rotating shaft 4, and an upper magnet 16 is fixedly connected to the lower surface of the turntable 5. The upper magnet 16 is symmetrically distributed about the center of the lower surface of the turntable 5. A connecting plate 14 is fixedly connected to the upper surface of the sliding column 13, and a lower magnet 15 is fixedly connected to the upper surface of the connecting plate 14. The magnetic poles on the upper surface of the lower magnet 15 are opposite to the magnetic poles on the lower surface of the upper magnet 16. A second spring 17 is fixedly connected to the lower surface of the connecting plate 14, and the other end of the second spring 17 is fixedly connected to the fixing block 7.

[0044] When the second rotating shaft 4 rotates, the turntable 5 fixedly connected to its upper surface rotates accordingly. Since the upper magnet 16 is symmetrically distributed about the center of the lower surface of the turntable 5, the upper magnet 16 also makes circular motion as the turntable 5 rotates. The lower magnet 15 is located on the upper surface of the sliding column 13 and is connected to the sliding column 13 through the connecting plate 14. The magnetic poles of the lower magnet 15 and the upper magnet 16 are opposite, so that the sliding column 13 slides inside the fixed block 7. When the magnetic force disappears, the second spring 17 returns the sliding column 13 to the initial position. At the same time, the second spring 17 effectively reduces the wear of the sliding column 13 on the air intake pipe 18 and extends the working life of the device.

[0045] Example 3: In this example, the difference from Example 2 is that... Figures 6-7 As shown:

[0046] A first spring 10 is fixedly connected to the surface of the fan 9, and the other end of the first spring 10 is fixedly connected to the fixed plate 11. A cam 8 is fixedly connected to the surface of the second rotating shaft 4, and the right side of the cam 8 is attached to the fan 9. A dustproof plate is provided inside the exhaust pipe 19, and the surface of the connecting rod 12 is convex.

[0047] When the second rotating shaft 4 rotates, it drives the lower cam 8 to rotate. Cam 8 periodically pushes the fan 9. Under the push of cam 8 and the elastic restoring force of spring 10, the fan 9 slides on the connecting rod 12, which can more comprehensively cover the space that needs dust removal, reduce dust accumulation, and reduce damage to the fan 9 components caused by stress concentration, thereby improving the dust removal efficiency of the device.

[0048] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
