Description
Technical Field
[0001] This utility model relates to the field of dust removal technology, and in particular to an energy-saving ventilation and dust removal device. Background Technology
[0002] In industrial plants and workshops, large amounts of dust and harmful gases are generated during production. If effective ventilation and dust removal are not carried out promptly, it will not only pose a serious threat to workers' health, causing occupational diseases such as pneumoconiosis, but also affect the normal operation of production equipment and reduce its lifespan. For example, in industries such as mining, cement production, and metal smelting, the amount of dust generated is enormous, and existing ventilation and dust removal devices often fail to meet the needs for efficient and comprehensive dust removal.
[0003] Traditional ventilation and dust removal devices often have the following technical drawbacks in practical applications: once the filter becomes clogged, frequent shutdowns are required to replace the filter, which not only increases labor costs and maintenance workload, but also leads to production interruptions and affects production efficiency. Utility Model Content
[0004] The purpose of this invention is to address the problems existing in the background technology by proposing an energy-saving ventilation and dust removal device.
[0005] The technical solution of this utility model is an energy-saving ventilation and dust removal device, which includes a dust removal shell, an exhaust pipe, an air inlet device, a filter assembly, and a dust removal assembly.
[0006] An air intake device is installed at one end of the dust collector housing; an exhaust pipe runs through the inside and outside of the dust collector housing; a filter assembly is located inside the dust collector housing, and the filter assembly includes an annular frame, an arc-shaped filter screen, and reinforcing rods. Two annular frames are arranged side-by-side, and multiple reinforcing rods are arranged in an annular array between the two annular frames. Multiple arc-shaped filters are also arranged between the two annular frames, with the multiple arc-shaped filters and multiple reinforcing rods spaced apart. A base plate is located at the bottom of the annular frame at the bottom, and a servo motor for driving the base plate to rotate is installed on the dust collector housing. An annular plate is located on the top annular frame, and the bottom of the exhaust pipe passes through the annular plate and communicates with the inside of the filter assembly. The dust collector assembly includes a fan, a first sealing cover, a second sealing cover, and a nozzle. The first and second sealing covers are located inside and outside the filter assembly, respectively. The nozzle is installed inside the second sealing cover, and the fan is installed outside the dust collector housing. A pipe connects the output end of the fan to the nozzle, and a dust discharge pipe is connected to the first sealing cover.
[0007] Preferably, the arc-shaped filter screen does not extend beyond the inner and outer sides of the annular frame and the reinforcing rod; the arc-shaped filter screen and the two reinforcing rods on the corresponding side have a detachable connection structure.
[0008] Preferably, the dust collector housing has an opening on its side, and a sealing cover is detachably installed on the dust collector housing near the opening. The sealing cover is made of transparent material, and a sealing gasket is installed on the inner side of the sealing cover.
[0009] Preferably, the air intake device includes an air intake pipe, an air intake fan, and multiple branch pipes. One end of the air intake pipe is open, the air intake fan is installed inside the air intake pipe, and the inner cavity of the air intake pipe is connected to the inner cavity of the dust collector housing through multiple branch pipes, which are arranged in a ring array.
[0010] Preferably, a sealing ring is installed on the outer periphery of the exhaust pipe to seal the gap between it and the annular plate.
[0011] Preferably, both the first sealing cover and the second sealing cover have openings on opposite sides, and each opening edge of the first sealing cover and the second sealing cover is provided with a sealing strip.
[0012] Compared with the prior art, the present invention has the following beneficial technical effects:
[0013] 1. This device uses a filter assembly with multiple arc-shaped filters and reinforcing rods spaced apart. Compared with traditional flat filters, arc-shaped filters have a larger filtration area, which can more effectively intercept impurities in the gas, greatly improve filtration efficiency, and ensure that the discharged air is cleaner.
[0014] 2. The device is equipped with a dust removal component. When the surface of the arc-shaped filter screen becomes clogged, the filter component is driven by a servo motor to rotate intermittently, so that the complete arc-shaped filter screen is covered by the first sealing cover and the second sealing cover. The high-speed airflow output by the fan blows the impurities into the first sealing cover and discharges them through the dust exhaust pipe. This automatic cleaning function avoids frequent shutdowns to replace the filter screen, reduces manual maintenance costs, and improves the continuous operation time and working efficiency of the device.
[0015] 3. The air intake device distributes air evenly to every corner of the dust collector housing through multiple branch pipes, ensuring sufficient filtration of the gas and reducing unnecessary energy consumption.
[0016] 3. The device has an independent dust removal gas channel, which is separated from the purification channel, and can complete the dust removal work simultaneously during the purification process. Attached Figure Description

Detailed Implementation
[0021] Example 1
[0022] like Figures 1-4 As shown in the figure, the energy-saving ventilation and dust removal device proposed in this embodiment includes a dust removal housing 1, an exhaust pipe 2, an air intake device, a filter assembly, and a dust removal assembly.
[0023] An air intake device is installed at one end of the dust collector housing 1. The air intake device includes an air intake pipe 3, an air intake fan 4, and multiple branch pipes 16. One end of the air intake pipe 3 is open. The air intake fan 4 is installed inside the air intake pipe 3. The inner cavity of the air intake pipe 3 is connected to the inner cavity of the dust collector housing 1 through multiple branch pipes 16. The multiple branch pipes 16 are arranged in a ring array. The exhaust pipe 2 penetrates the inner and outer sides of the dust collector housing 1.
[0024] The filter assembly is located inside the dust collector housing 1. The filter assembly includes an annular frame 91, an arc-shaped filter screen 92, and reinforcing rods 93. There are two annular frames 91 arranged side by side. Multiple reinforcing rods 93 are arranged in an annular array between the two annular frames 91. Multiple arc-shaped filter screens 92 are arranged and installed between the two annular frames 91. The multiple arc-shaped filter screens 92 and multiple reinforcing rods 93 are spaced apart from each other. A base plate 13 is provided at the bottom end of the annular frame 91 at the bottom. A servo motor 7 for driving the base plate 13 to rotate is installed on the dust collector housing 1. An annular plate 14 is provided on the annular frame 91 at the top. The bottom of the exhaust pipe 2 passes through the annular plate 14 and communicates with the inside of the filter assembly. A sealing ring 15 for sealing the gap between the exhaust pipe 2 and the annular plate 14 is installed on the outer periphery of the exhaust pipe 2.
[0025] The dust removal assembly includes a fan 6, a first sealing cover 10, a second sealing cover 11, and a nozzle 12. The first sealing cover 10 and the second sealing cover 11 are respectively located on the inner and outer sides of the filter assembly. The first sealing cover 10 is fixedly connected to the inner wall of the dust removal housing 1, and the second sealing cover 11 is fixedly connected to the exhaust pipe 2. The nozzle 12 is installed inside the second sealing cover 11. The opposite sides of the first sealing cover 10 and the second sealing cover 11 are both open. A sealing strip is provided around the edge of the opening of the first sealing cover 10 and the second sealing cover 11. The fan 6 is installed outside the dust removal housing 1. A pipe is connected between the output end of the fan 6 and the nozzle 12. A dust discharge pipe 8 is connected to the first sealing cover 10.
[0026] This technical solution uses a microcontroller or PLC controller to control the entire device.
[0027] The working principle of this technical solution is as follows:
[0028] The intake fan 4 is installed inside the intake pipe 3, which can continuously draw in outside air into the intake pipe 3. The inner cavity of the intake pipe 3 is connected to the inner cavity of the dust collector housing 1 through multiple branch pipes 16. This structure allows the air entering the intake pipe 3 to be evenly distributed to all corners of the inner cavity of the dust collector housing 1 through multiple branch pipes 16, ensuring the efficiency and comprehensiveness of the entire dust removal process. Through the even distribution of multiple branch pipes 16, the air can fully contact the subsequent filter components, thereby improving the gas filtration effect.
[0029] When air containing impurities enters the inner cavity of the dust collector housing 1 through the branch pipe 16, it will come into contact with the arc-shaped filter 92. The unique design of the arc-shaped filter 92 has a larger filtration area than the traditional flat filter, which can more effectively intercept impurities in the gas. When the air passes through the arc-shaped filter 92, the dust, particles and other impurities in it will be intercepted by the filter, while the clean air will continue to flow towards the exhaust pipe 2 and eventually be discharged into the room, providing fresh air for the room.
[0030] As the filtration process continues, impurities gradually accumulate on the surface of the arc-shaped filter screen 92, leading to filter clogging, affecting the filtration effect, and consequently impacting the energy efficiency of the device. At this point, the dust removal assembly needs to be activated to clean the arc-shaped filter screen 92. The servo motor 7 is activated to drive the filter assembly to rotate intermittently. The single rotation angle of the filter assembly is 360 / N, where N is the number of arc-shaped filters 92. When the complete arc-shaped filter screen 92 is covered by the first sealing cover 10 and the second sealing cover 11 on its inner and outer sides respectively, the sealing strips at the upper and lower ends of the first sealing cover 10 contact the two annular frames 91, and the sealing strips at the left and right ends of the first sealing cover 10 contact the two corresponding sides... The reinforcing frame 93 contacts the first sealing cover 11, thus forming a relatively sealed space to ensure that dust does not leak into the purification area during the dust removal process. When the fan 6 is started, it outputs a high-speed airflow to the nozzle 12. The high-speed airflow blows the impurities on the surface of the arc-shaped filter screen 92 into the first sealing cover 10. The first sealing cover 10 is connected to a dust discharge pipe 8, and the blown-off impurities are discharged through the dust discharge pipe 8. A cloth bag can be installed at the end of the dust discharge pipe 8 to collect dust. Through the above dust removal method, an independent dust removal gas channel is formed, enabling the device to complete the dust removal work during the purification process, which greatly improves the working efficiency of the device.
[0031] Example 2
[0032] like Figure 1 and Figure 4 As shown, in this embodiment, an energy-saving ventilation and dust removal device is proposed. Compared with the first embodiment, in this embodiment, the arc-shaped filter 92 does not extend beyond the inner and outer sides of the annular frame 91 and the reinforcing rod 93; the arc-shaped filter 92 and the two reinforcing rods 93 on the corresponding side have a detachable connection structure, and the detachable method can be screws or sealant; the dust removal housing 1 has an opening on its side, and a sealing cover 5 is detachably installed on the dust removal housing 1 near its opening. The detachable method can be screws, the sealing cover 5 is made of transparent material, and a sealing gasket is installed on the inner side of the sealing cover 5;
[0033] In this embodiment, the above design allows operators to easily repair or replace individual arc-shaped filters 92. When an arc-shaped filter 92 is damaged or severely clogged and cannot be cleaned by the dust removal component, the operator can open the sealing cover 5 and remove the damaged arc-shaped filter 92 through the detachable connection structure, and then replace it with a new arc-shaped filter 92. Compared with the cylindrical filter, this method of replacing individual arc-shaped filters 92 is less costly.
[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
