Technical Field

[0001] This utility model relates to the field of air curtain equipment technology, specifically to an air curtain dust collection and removal device for safety engineering. Background Technology

[0002] Air curtain equipment uses a high-speed motor to drive a cross-flow or centrifugal fan to generate a powerful airflow, forming an air curtain that can effectively block the flow of dust between indoors and outdoors, concentrating the dust in the corresponding construction area for convenient centralized treatment later. It is especially commonly used in safety engineering.

[0003] Most of the air curtain dust collection and removal devices commonly used in safety engineering on the market are similar in structure, with a stainless steel equipment shell as the main body. The top is usually equipped with two sets of centrifugal fans, and the bottom has an air collection hood for gathering airflow. In actual use, there are some functional deficiencies and room for improvement. For example, during long-term use, a large amount of dust or lint easily adheres to the surface of the filter screen. Cleaning requires disassembling the equipment, opening the shell, and taking out the filter screen, which is quite troublesome and does not have the function of easy filter screen replacement.

[0004] Now, a novel air curtain dust collection and removal device for safety engineering is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a dust collection and removal device for air curtains used in safety engineering, in order to solve the problem mentioned in the background art of not having the function of easy filter replacement.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dust collection and removal device for safety engineering, comprising a main housing, a dust collection hood fixedly connected to the bottom of the main housing, a top cover fixedly connected to the top of the main housing, centrifugal fans installed on both sides of the top of the top cover, sensor mounting bases fixedly connected to both sides of the rear end of the main housing, three sets of lamp mounting bases installed at the top of the top of the top cover, multiple sets of ultraviolet germicidal lamps installed at the bottom of the lamp mounting bases, and a filter replacement structure provided at the front end of the main housing.

[0007] The filter replacement structure includes two sets of side guide frames, which are fixedly connected to both sides inside the main housing of the equipment. A nylon filter is inserted into the front end of the main housing of the equipment, and a front sealing plate is fixedly connected to the front end of the nylon filter. Two sets of hand-tightening bolts are inserted into both sides of the front end of the front sealing plate. Fixed angle irons are fixedly connected to both sides of the main housing of the equipment, and two sets of internally threaded pipe seats are fixedly connected to the rear end of the fixed angle irons.

[0008] Preferably, the bottom end of the nylon filter is in contact with the top end of the side guide frame, and the nylon filter can slide back and forth along the top end of the side guide frame.

[0009] Preferably, the front end of the front sealing plate is fixedly connected to two sets of handles, and the rear end of the front sealing plate is fitted with the front end of the main housing of the equipment.

[0010] Preferably, the hand-tightening bolt passes through the interior of the front sealing plate and extends into the interior of the internally threaded pipe seat, and the external threads of the hand-tightening bolt and the internal threads of the internally threaded pipe seat match.

[0011] Preferably, an air inlet is provided below the centrifugal fan, and the sensor mounting bases are symmetrically distributed about the vertical center line of the main housing of the equipment.

[0012] Preferably, a wind pressure sensor is installed inside the front end of the sensor mounting base, and the top of the sensor mounting base and the wind pressure sensor is lower than the bottom of the side guide frame.

[0013] Preferably, the ultraviolet germicidal lamps are arranged at equal intervals, and the bottom of the ultraviolet germicidal lamps is higher than the top of the nylon filter.

[0014] Preferably, a remote control switch is provided on one side of the lamp mounting base, and the ultraviolet germicidal lamp and the remote control switch are electrically connected.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the air curtain dust collection and removal device for safety engineering not only realizes the function of easy filter replacement and real-time monitoring of air pressure, but also realizes the function of internal sterilization and disinfection.

[0016] (1) The equipment is equipped with a side guide frame, a front sealing plate, handles, hand-tightening bolts, nylon filter screen, fixed angle iron and internal threaded pipe seat. When in use, the equipment is installed on the top of the entrance of the construction site of the safety project. The centrifugal fan continuously sends air into the main shell of the equipment through the air inlet on the top cover. The air pressure inside the main shell of the equipment increases, and the airflow rushes out along the opening at the bottom of the air collection cover to form an air curtain, which isolates the dust inside the construction site and concentrates it in the construction area to prevent it from escaping. The nylon filter screen can isolate dust and lint in the airflow generated by the centrifugal fan. When the nylon filter screen needs to be replaced and cleaned, the operator only needs to loosen and pull out the four sets of hand-tightening bolts. After the hand-tightening bolts are separated from the internal threaded pipe seat on the fixed angle iron, grab the two sets of handles on the front sealing plate and pull them outward. The front sealing plate and the nylon filter screen can be pulled out at the same time. The side guide frame can support the nylon filter screen, making it easy to insert and pull out, thus realizing the function of easy filter screen replacement.

[0017] (2) With the sensor mounting base and wind pressure sensor installed, when in use, the strong airflow generated by the centrifugal fan continues to flow down along the top cover, the main housing of the equipment and the inside of the air collection hood. The wind pressure sensor keeps monitoring the wind pressure of the airflow, which makes it convenient for users to obtain information. When the wind pressure is significantly lower, the equipment can be checked in time to determine whether there is a problem with the centrifugal fan or the nylon filter needs to be replaced, so as to avoid insufficient air curtain isolation capacity due to untimely maintenance. The sensor mounting base provides physical support for the installation and fixation of the wind pressure sensor, realizing the function of real-time monitoring of wind pressure.

[0018] (3) By setting up a lamp mounting base, an ultraviolet germicidal lamp and a remote control switch, when the nylon filter screen intercepts dust and lint in the airflow, its surface is also an area where bacteria can easily grow. Operators can periodically turn on the ultraviolet germicidal lamp at the bottom of the lamp mounting base through the remote control switch. The ultraviolet germicidal lamp irradiates the nylon filter screen for one hour at a time to kill the bacteria on its surface, avoid odor and mold, and achieve the function of internal sterilization and disinfection.

[0024] 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.

[0025] Example 1: Please refer to Figure 1-4A dust collection and removal device for safety engineering includes a main housing 1, a dust collection hood 2 fixedly connected to the bottom of the main housing 1, a top cover 12 fixedly connected to the top of the main housing 1, centrifugal fans 17 installed on both sides of the top of the top cover 12, and a filter replacement structure provided at the front end of the main housing 1.

[0026] Please see Figure 1-4 A dust collection and removal device for safety engineering also includes a filter replacement structure. The filter replacement structure includes two sets of side guide frames 3, which are fixedly connected to both sides inside the main housing 1 of the equipment. A nylon filter 7 is inserted into the front end of the main housing 1 of the equipment. A front sealing plate 4 is fixedly connected to the front end of the nylon filter 7. Two sets of hand-tightening bolts 6 are inserted into both sides of the front end of the front sealing plate 4. Fixed angle irons 8 are fixedly connected to both sides of the main housing 1 of the equipment. Two sets of internally threaded pipe seats 9 are fixedly connected to the rear end of the fixed angle irons 8.

[0027] The bottom end of the nylon filter screen 7 contacts the top end of the side guide frame 3. The nylon filter screen 7 can slide back and forth along the top end of the side guide frame 3. Two sets of handles 5 are fixedly connected to the front end of the front end sealing plate 4. The rear end of the front end sealing plate 4 fits against the front end of the main housing 1 of the equipment. The hand-tightening bolt 6 passes through the interior of the front end sealing plate 4 and extends into the interior of the internal threaded tube seat 9. The external thread of the hand-tightening bolt 6 matches the internal thread of the internal threaded tube seat 9, which facilitates the disassembly and assembly of the filter screen.

[0028] Specifically, such as Figure 2 and Figure 3 As shown, the nylon filter 7 can isolate dust and lint in the airflow generated by the centrifugal fan 17. When the nylon filter 7 needs to be replaced and cleaned, the operator only needs to loosen and pull out the four sets of hand-tightening bolts 6. After the hand-tightening bolts 6 are disengaged from the internal threaded tube seat 9 on the fixed angle iron 8, the operator can grasp the two sets of handles 5 on the front sealing plate 4 and pull them outward. The front sealing plate 4 and the nylon filter 7 can be pulled out simultaneously. The side guide frame 3 can support the nylon filter 7, making it easy to insert and remove.

[0029] Example 2: Sensor mounting bases 10 are fixedly connected to both sides of the rear end of the main housing 1 of the equipment. An air inlet 13 is provided below the centrifugal fan 17. The sensor mounting bases 10 are symmetrically distributed about the vertical center line of the main housing 1 of the equipment. A wind pressure sensor 11 is installed inside the front end of the sensor mounting base 10. The top of the sensor mounting base 10 and the wind pressure sensor 11 are lower than the bottom of the side guide frame 3, so that the wind pressure can be monitored in real time and the user can control it.

[0030] Specifically, such as Figure 1 and Figure 2As shown, the wind pressure sensor 11 keeps monitoring the wind pressure of the airflow, making it convenient for users to obtain information. When the wind pressure is significantly lower, the equipment can be checked in time to determine whether the centrifugal fan 17 is malfunctioning or the nylon filter 7 needs to be replaced, thus avoiding insufficient air curtain isolation capacity due to untimely maintenance. The sensor mounting base 10 provides physical support for the installation and fixation of the wind pressure sensor 11.

[0031] Example 3: Three sets of lamp mounting bases 14 are installed at the top of the inside of the top cover 12. Multiple sets of ultraviolet germicidal lamps 15 are installed at the bottom of the lamp mounting bases 14. The ultraviolet germicidal lamps 15 are arranged at equal intervals. The bottom of the ultraviolet germicidal lamps 15 is higher than the top of the nylon filter 7. A remote control switch 16 is provided on one side of the lamp mounting base 14. The ultraviolet germicidal lamps 15 and the remote control switch 16 are electrically connected, which can regularly disinfect the inside of the equipment and reduce the growth of bacteria and odors.

[0032] Specifically, such as Figure 1 and Figure 4 As shown, the ultraviolet germicidal lamp 15 at the bottom of the lamp mounting base 14 is turned on periodically via remote control switch 16. The ultraviolet germicidal lamp 15 irradiates the nylon filter 7 for one hour at a time to kill bacteria on its surface and prevent odors, mold and other problems from occurring.

[0033] Working principle: When using this utility model, firstly, the equipment is installed on the top of the entrance to the construction site of the safety project. The centrifugal fan 17 continuously supplies air into the main housing 1 of the equipment through the air inlet 13 on the top cover 12. The air pressure inside the main housing 1 increases, and the airflow rushes out along the opening at the bottom of the air collecting cover 2, forming an air curtain to isolate the dust inside the construction site and concentrate it in the construction area to prevent it from escaping. The nylon filter 7 can isolate dust and lint in the airflow generated by the centrifugal fan 17. When the nylon filter 7 needs to be replaced and cleaned, the operator only needs to loosen and pull out the four sets of hand-tightening bolts 6. After the hand-tightening bolts 6 are released from the internal threaded pipe seat 9 on the fixed angle iron 8, the operator can grab the two sets of handles 5 on the front sealing plate 4 and pull them outward. The front sealing plate 4 and the nylon filter 7 can be pulled out simultaneously. The side guide frame 3 can support the nylon filter 7 to facilitate its insertion and removal. The strong airflow generated by the centrifugal fan 17 continuously flows downwards along the interior of the top cover 12, the main housing 1, and the air collection hood 2. The wind pressure sensor 11 continuously monitors the wind pressure of the airflow, facilitating information acquisition for the user. When the wind pressure is significantly low, the equipment can be checked promptly to determine whether the problem lies with the centrifugal fan 17 or the nylon filter 7 needs replacement, preventing insufficient air curtain isolation due to delayed maintenance. The sensor mounting base 10 provides physical support for the installation and fixation of the wind pressure sensor 11. While the nylon filter 7 intercepts dust and lint in the airflow, its surface is also an area prone to bacterial growth. Operators periodically activate the ultraviolet germicidal lamp 15 at the bottom of the lamp mounting base 14 via the remote control switch 16. The ultraviolet germicidal lamp 15 irradiates the nylon filter 7 for one hour at a time to kill bacteria on its surface, preventing odors and mold growth.

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.
