Description

Technical Field

[0001] This utility model relates to the field of dust removal technology, specifically an explosion-proof dust removal and environmental protection device. Background Technology

[0002] Dust removal and environmental protection equipment is used to remove dust from air containing different types of dust, such as flour dust, chemical dust, and coal dust. In order to prevent the explosion of dust-laden air caused by electrostatic spark discharge of traditional electrostatic dust removal equipment, most dust removal equipment currently uses materials that can both prevent static electricity and filter dust to make filter screens or filter cartridges to filter dust. For example, conductive fiber yarns are incorporated into the warp yarns of the filter screen base fabric or conductive fibers are mixed into chemical fibers to form a conductive network, which can effectively prevent static electricity and achieve the effect of explosion-proof dust removal.

[0003] During the dust filtration process, dust accumulates on the filter surface over time, reducing the filter's air permeability. Currently, the filter can be cleaned by using flowing air to backflush the dust on the inlet side. However, the filter itself has a large area, making it difficult to achieve high-velocity airflow across different areas. Furthermore, the dust removal equipment cannot continue dust removal during the filter cleaning process because the flow direction of the dust-laden air is opposite to the flow direction of the air backflushing to clean the filter, thus hindering the passage of dust-laden air through the filter. Utility Model Content

[0004] The purpose of this utility model is to provide an explosion-proof dust removal and environmental protection device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An explosion-proof dust removal and environmental protection device includes:

[0007] The machine platform, with a dust collection box installed at its bottom;

[0008] A dust collection box is fixed to the machine base, and an air inlet hood and an exhaust pipe are fixedly connected to the outside of the dust collection box;

[0009] A dust removal assembly, arranged inside a dust removal box, is capable of filtering air containing dust. The dust removal assembly includes two drive wheels that are rotatably connected to the dust removal box, and a belt filter screen is driven between the two drive wheels.

[0010] A cleaning component, embedded and fixed with the dust collection box, is capable of cleaning dust adhering to the outside of the strip filter. The cleaning component includes a cleaning cover, which is fitted onto the outside of the strip filter and is connected and fixed to the suction end of an external vacuum cleaner.

[0011] Both the humidifier and the humidity sensor are fixed to the machine. The humidifier reduces static electricity accumulation by increasing the humidity of dust-laden air, and the humidity sensor turns the humidifier on or off by detecting the humidity of dust-laden air.

[0012] Furthermore, the ash collection box has a brush fixed to its opening to abut against the strip filter screen, and one end of the air intake hood is connected to and fixed with an air intake pipe.

[0013] Furthermore, a connecting pipe is fixedly connected between the humidifier and the air intake cover, and the humidity sensor is fixedly connected to a humidity detection probe via a cable, with the humidity detection probe being plugged into and fixed to the air intake cover.

[0014] Furthermore, the dust removal assembly also includes two connecting shafts that are rotatably connected to the dust removal box, and multiple support blocks that are fixedly connected to the transmission wheel are fixed on the outer side of the connecting shafts.

[0015] Furthermore, a motor is fixed to the outside of the dust collection box, and the output end of the motor is fixedly connected to the corresponding connecting shaft.

[0016] Furthermore, one end of the cleaning cover has a notch for accommodating a strip filter, and a plurality of brushes capable of contacting the strip filter are fixed inside the notch.

[0017] Furthermore, a vacuum tube is fixedly connected to the outside of the cleaning cover, and the vacuum tube is fixedly connected to the suction end of an external vacuum cleaner.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. A belt filter is connected inside the dust collector. Dust-laden air is transported to the outside of the belt filter through the air inlet hood. After passing through the belt filter, the dust-laden air is discharged through the exhaust pipe. The belt filter filters the dust in the dust-laden air. A motor drives one of the drive wheels to rotate counterclockwise, which moves the belt filter towards the first brush. The first brush can scrape and clean the dust attached to the outside of the belt filter. The cleaned dust can fall into the dust collection box for collection, which helps to achieve automatic cleaning of the dust attached to the belt filter.

[0020] 2. A cleaning hood is embedded and fixed on one side of the dust collection box. Multiple brushes are fixed inside the cleaning hood, each in contact with the strip filter. The cleaning hood is connected to an external vacuum cleaner via a suction pipe. When the strip filter passes through the cleaning hood, the vacuum cleaner can simultaneously suck up the dust on the strip filter from both the inside and outside of the strip filter. At the same time, the brushes can rub against the moving strip filter, accelerating the removal of dust from the strip filter and its removal by the vacuum cleaner. This improves the cleaning efficiency of the strip filter. Furthermore, as the motor drives the strip filter, the clean strip filter can be transferred to the filtration position facing the air intake hood, which helps maintain the filter's permeability for filtering dust over a long period.

[0021] 3. By incorporating conductive fiber yarns into the warp yarns of the strip filter mesh in the base fabric, a conductive network is formed, which can effectively discharge static electricity and help prevent accidental explosions during dust removal of dusty air. By installing a humidity detection probe inside the air intake hood, the humidity of the dusty air can be detected. If the air is relatively dry, the humidity can be increased by turning on a humidifier. Moisture particles in the air can attract and neutralize charged particles, thereby reducing the volume resistivity of dust and reducing static electricity accumulation, further preventing accidental explosions during dust removal of dusty air and improving the safety of dust removal.

[0022] 4. While the cleaning component is cleaning the strip filter, a clean strip filter is always removed to filter dust. This allows the filtration of dusty air and the cleaning of the strip filter to be carried out simultaneously, which helps to improve the overall efficiency of dust removal and filter cleaning.

Detailed Implementation

[0028] 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.

[0029] Example 1, please refer to Figure 1 - Figure 4 In this embodiment of the present invention, an explosion-proof dust removal and environmental protection device includes a machine base 100. A dust collection box 110 is detachably installed and fixed to the bottom of the machine base 100. A dust collection box 200 is fixedly connected to the top surface of the machine base 100. An air inlet hood 210 and an exhaust pipe 220 are connected and fixed to the outside of the dust collection box 200. The bottom end of the dust collection box 200 is connected to the open opening of the dust collection box 110. A dust removal assembly 300 is installed inside the dust collection box 200. The dust removal assembly 300 includes two components, each connected to the dust collection box 200. A drive wheel 310 is rotatably connected to the dust collection box 200. A strip filter 320 is connected between the two drive wheels 310. A cleaning component 400 is embedded and fixed on one side of the dust collection box 200. The cleaning component 400 includes a cleaning cover 410 fixedly connected to the dust collection box 200. The cleaning cover 410 is sleeved on the outside of the strip filter 320. The cleaning cover 410 is connected and fixedly connected to the suction end of the external vacuum cleaner. A humidifier 500 and a humidity sensor 600 are fixedly connected to the top of the machine base 100.

[0030] Specifically, by designing the traditional sheet filter as a movable strip filter 320, the strip filter 320 not only filters dust like a traditional filter, but also moves the dust to the cleaning hood 410 during the dust filtration process. An external vacuum cleaner can then draw in the airflow from the cleaning hood 410, thereby removing dust from the outside of the strip filter 320. Different areas of the strip filter 320 can be cleaned through the cleaning hood 410, facilitating all-round automatic cleaning of the strip filter 320. This helps improve the permeability of the strip filter 320 and eliminates the need for traditional airflow backflushing of dust on the filter, which cannot perform all-round cleaning of the entire filter. Furthermore, by rotating the strip filter 320 within the dust collection box 200, dust removal of the dusty air and cleaning of the strip filter 320 can be carried out simultaneously, solving the problem that dust removal equipment cannot continue dust removal operations when cleaning the filter.

[0031] like Figure 3 As shown, in this embodiment, the strip filter 320 is generally ring-shaped, enabling transmission between the two drive wheels 310. The strip filter 320 can also be made by blending conductive fibers such as carbon fiber into the filter material to form a three-dimensional conductive network, which can also quickly discharge static electricity. The specific dust removal and anti-static explosion-proof design of the filter is existing technology and will not be described in detail here.

[0032] like Figure 3 As shown, in this embodiment, the opening of the dust collection box 110 is fixedly connected to a brush 111 that can abut against the strip filter screen 320, so that when the strip filter screen 320 passes through the brush 111, the brush 111 can initially clean the dust on the outside of the filter screen and let it fall into the dust collection box 110.

[0033] like Figure 1 As shown, in this embodiment, one end of the air intake hood 210 is connected to and fixed with an air intake pipe 211. One end of the air intake pipe 211 is connected to and fixed with an external pipe that pumps dust-laden air through a connecting flange, so that the external dust-laden air can enter the dust collection box 200 for dust removal operation through the air intake pipe 211 and the air intake hood 210.

[0034] like Figure 1 and Figure 2As shown, in this embodiment, a connecting pipe 510 is fixedly connected between the humidifier 500 and the air intake hood 210. The connecting pipe 510 can transport the mist generated by the humidifier 500 into the air intake hood 210 to reduce the dryness of the dusty air. The humidity sensor 600 is connected to a humidity detection probe 610 via a cable. The humidity detection probe 610 is plugged into and fixed to the air intake hood 210. The humidity detection probe 610 and the humidity sensor 600 work together to monitor the humidity of the dusty air in real time, and then turn on the humidifier 500 when the dusty air is relatively dry. The humidifier 500 and the humidity sensor 600 are both existing technology components, and their specific working principles will not be described in detail.

[0035] like Figure 1 and Figure 3 As shown, in this embodiment, the dust removal assembly 300 also includes two connecting shafts 330 that are rotatably connected to the dust removal box 200. Multiple support blocks that are fixedly connected to the transmission wheel 310 are fixed on the outer side of the connecting shafts 330. A motor 230 that can drive the connecting shafts 330 to rotate is fixed on the outer side of the dust removal box 200.

[0036] In this embodiment, the motor drive 230 causes the connecting shaft 330 to rotate counterclockwise, which in turn causes the two transmission wheels 310 to rotate counterclockwise, thereby enabling the strip filter screen 320 to move between the cleaning position and the filtering position, so that filtration and cleaning can be performed simultaneously.

[0037] like Figure 4 As shown, in this embodiment, one end of the cleaning cover 410 is provided with a notch 420 for accommodating the strip filter 320. Multiple brushes 430 that can abut against the strip filter 320 are fixedly connected at equal intervals on both sides of the inside of the notch 420. This allows the brushes 430 to scrape and clean the filter again as the strip filter 320 passes through the multiple brushes 430, promoting the cleaning cover 410 to quickly suck up the dust outside the filter.

[0038] In this embodiment, a suction pipe 440 is fixedly connected to the outside of the cleaning cover 410. The suction pipe 440 is fixedly connected to the suction end of an external vacuum cleaner. When it is necessary to clean the dust on the outside of the strip filter 320, the external vacuum cleaner can be turned on to suck the air inside the cleaning cover 410, which helps to clean the dust on the outside of the strip filter 320.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0040] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
