Description

Technical Field

[0001] The utility model relates to the technical field of dust removal air boxes, in particular to a vertical dust removal air box for a factory building. Background Technique

[0002] During the working process of a factory building, a large amount of smoke and dust may sometimes be generated. If these generated smoke and dust are not processed in time, it will not only affect the normal operation of the factory products, but also pose a hazard to the physical health of people if they work in a factory building with smoke and dust for a long time.

[0003] Therefore, a dust removal air box is needed at this time. According to a Chinese patent with the application number 202320048711.0, a vertical dust removal air box for a factory building, when in use, the ventilation fan generates suction in the ventilation space, and the air mixed with smoke and dust in the factory building is sucked into the ventilation space under the action of the ventilation fan. When the air enters the ventilation space through the dust removal plate, it will pass through the dust removal pad, and the smoke and dust in the air will be adsorbed by the dust removal pad to achieve the purpose of filtering the air. However, this device can only systematically filter the dust inside the entire factory building during use. When there are workstations in the factory building for welding or cutting, this device cannot further suck and remove dust at these welding or cutting positions. Therefore, an improved vertical dust removal air box for a factory building is needed to solve this problem. Content of the Utility Model

[0004] The purpose of the utility model is to provide a vertical dust removal air box for a factory building to solve the problems raised in the above background technique.

[0005] To achieve the above object, the utility model provides the following technical solution: A vertical dust removal air box for a factory building, comprising a housing. An air inlet chamber is provided at the lower end inside the housing, and an air inlet is provided on the outer surface of the air inlet chamber. A filtering mechanism is provided above the air inlet chamber inside the housing. The filtering mechanism includes a fixed frame, connecting columns, a movable frame, filter tubes, and air outlets. A fixed frame is provided at the upper end inside the housing, and connecting columns are movably inserted through the four corners of the outer surface of the fixed frame. A movable frame is fixedly provided at the lower end of the connecting columns. A plurality of filter tubes are evenly and fixedly provided on the outer surface of the lower end of the movable frame. A filter element is provided inside the filter tubes, and air outlets are provided on the outer surface of the upper end of the filter tubes. Expansion mechanisms are provided on both sides of the surface of the air inlet chamber. The expansion mechanisms include expansion interfaces, sealing rings, connection interfaces, dust suction pipes, butterfly plates, connecting plates, and locking screws. Expansion interfaces are fixedly provided on both sides of the surface of the air inlet chamber. The expansion interfaces are in mutual communication with the inside of the air inlet chamber. A sealing ring is fixedly provided on the outer surface of the expansion interfaces. A connection interface is provided on the outer surface of the expansion interfaces by interference connection through the sealing ring. A dust suction pipe is fixedly provided on the surface of the connection interface. A butterfly plate is movably provided inside the expansion interfaces through a rotating shaft. A connecting plate is fixedly provided at the upper end of the rotating shaft where the butterfly plate is located. A locking screw is provided between the connecting plate and the expansion interfaces. A sealed box door is movably provided on the surface of the housing through a hinge. Universal wheels are movably provided at the four corners of the lower surface of the housing.

[0006] Preferably, a blower chamber is fixedly provided at the upper end of the housing, and a volute blower is fixedly provided inside the blower chamber. The air inlet end of the volute blower is in mutual communication with the inside of the housing. An air outlet groove is provided on the outer surface of the lower end of the blower chamber. The volute blower can extract the air inside the housing and then discharge it from the air outlet groove. At this time, a negative pressure is formed inside the housing. Subsequently, the air in the factory building can be inhaled into the air inlet chamber through the air inlet, and then the air inside the air inlet chamber passes through the filter tubes. After being filtered by the filter elements inside the filter tubes, the dust is intercepted, and the air is supplemented into the housing through the air outlets. In this way, an air flow cycle can be formed, playing a role in filtering and removing dust from the air inside the factory building.

[0007] Preferably, a dust collection drawer is movably clamped at the lower end inside the housing of the air inlet chamber. The dust collection drawer can facilitate the collection of the dust filtered by the filter tubes, facilitating the subsequent extraction of the dust collection drawer by the staff to uniformly process this dust.

[0008] Preferably, a rubber ring is fixedly provided on the outer surface of the upper end of the filter tubes and the air inlet chamber. The filter tubes are in mutual communication with the inside of the air inlet chamber. Since this device also has the function of vibrating to remove the dust inside the filter tubes, through the elasticity of this rubber ring itself, the filter tubes have a space for moving up and down, thus facilitating the shaking off of the dust.

[0009] Preferably, a vibration motor is fixedly arranged at the upper end of the fixed frame. The vibration motor can generate vibration (the vibration principle is that the motor drives an eccentric counterweight to rotate, and the centrifugal force of the counterweight is used to generate vibration. This principle is a common means of vibration motors in the prior art, so the specific structure of the vibration motor is not introduced in detail in this application document), so as to clean the dust filtered inside the filter pipe.

[0010] Preferably, a limit screw is fixedly arranged at the upper end of the connecting column, and a spring is sleeved on the outer surface of the connecting column between the limit screw and the fixed frame. The spring can automatically push the movable frame to move upward and reset. In this way, cooperating with the vibration motor to drive the movable frame can make the movable frame and the filter pipe swing up and down continuously. In this way, the dust inside the filter pipe can be shaken off, so that the dust inside the filter pipe can fall and deposit in the ash collection drawer.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. The present utility model is provided with an expansion interface. Through the expansion interface, the dust suction pipe can be quickly and interference-fitted, so that the dust suction pipe can be connected at any time according to needs. In this way, when there are workers cutting and welding in the workshop, the dust suction pipe can be used to focus on adsorbing the dust generated by the work in the working area, so as to improve the adsorption and dust removal effect; the unused expansion mechanism can be sealed by a butterfly plate according to needs.

[0013] 2. When the present utility model is in use, vibration is generated by the vibration motor. The vibration can drive the movable frame, so that the movable frame and the filter pipe can swing up and down continuously. In this way, the dust inside the filter pipe can be shaken off, so that the dust inside the filter pipe can fall and deposit in the ash collection drawer, making the ash cleaning of this device convenient.

At the lower end inside the housing 1, there is an air inlet chamber 2. On the outer surface of the air inlet chamber 2, there is an air inlet 3. Inside the housing 1, above the air inlet chamber 2, there is a filtering mechanism. The filtering mechanism includes a fixed frame 4, connecting columns 5, a movable frame 6, filter tubes 7, and an air outlet 8. At the upper end inside the housing 1, there is a fixed frame 4. At the four corners of the outer surface of the fixed frame 4, connecting columns 5 are movably inserted. At the lower end of the connecting columns 5, there is a fixed movable frame 6. On the outer surface of the lower end of the movable frame 6, a number of filter tubes 7 are evenly fixed. Inside the filter tubes 7, there is a filter element. On the outer surface of the upper end of the filter tubes 7, there is an air outlet 8. On both sides of the surface of the air inlet chamber 2, there is an expansion mechanism. The expansion mechanism includes an expansion interface 9, a sealing ring 10, a connecting interface 11, a dust suction pipe 12, a butterfly plate 13, a connecting plate 14, and a locking screw 15. On both sides of the surface of the air inlet chamber 2, there are fixed expansion interfaces 9. The expansion interfaces 9 are in mutual communication with the inside of the air inlet chamber 2. On the outer surface of the expansion interface, there is a fixed sealing ring 10. On the outer surface of the expansion interface 9, a connecting interface 11 is connected by interference fit through the sealing ring 10. On the surface of the connecting interface 11, there is a dust suction pipe 12. Inside the expansion interface 9, there is a butterfly plate 13 arranged through a rotating shaft. At the upper end of the rotating shaft where the butterfly plate 13 is located, there is a connecting plate 14. Between the connecting plate 14 and the expansion interface 9, there is a locking screw 15. On the surface of the housing 1, there is a sealed box door 16 arranged through a hinge. At the four corners of the lower end surface of the housing 1, there are movable universal wheels 17.

[0023] At the upper end of the housing 1, there is a fixed blower chamber 18. Inside the blower chamber 18, there is a volute blower 19. The air inlet end of the volute blower 19 is in mutual communication with the inside of the housing 1. On the outer surface of the lower end of the blower chamber 18, there is an air outlet groove 20. Through the volute blower 19, the air inside the housing 1 can be pumped out and then discharged from the air outlet groove 20. At this time, a negative pressure is formed inside the housing 1. Subsequently, the air in the factory building can be inhaled into the air inlet chamber 2 through the air inlet 3. Then, the air inside the air inlet chamber 2 passes through the filter tubes 7. After being filtered by the filter element inside the filter tubes 7, the dust is intercepted, and the air is supplemented into the housing 1 through the air outlet 8. In this way, an air flow cycle can be formed, playing a role in filtering and removing dust from the air inside the factory building.

[0026] A vibration motor 23 is fixedly arranged at the upper end of the fixed frame 4. Vibration can be generated by the vibration motor 23 (the vibration principle is that a motor drives an eccentric counterweight to rotate, and the centrifugal force of the counterweight is used to generate vibration. This principle is a common means of the vibration motor 23 in the prior art, so the specific structure of the vibration motor 23 is not introduced too much in this application document), so that the dust filtered inside the filter tube 7 can be cleaned;

[0027] A limit screw 24 is fixedly arranged at the upper end of the connecting column 5. A spring 25 is sleeved on the outer surface of the connecting column 5 between the limit screw 24 and the fixed frame 4. The spring 25 can automatically push the movable frame 6 to move up and reset.

[0028] Working principle: When using this device, the air inside the housing 1 can be pumped out through the volute fan 19 and then discharged from the air outlet groove 20. At this time, a negative pressure is formed inside the housing 1. Subsequently, the air in the workshop can be inhaled into the intake chamber 2 through the air inlet 3. Then the air inside the intake chamber 2 passes through the filter tube 7, and the dust is intercepted after being filtered by the filter element inside the filter tube 7, while the air is supplemented into the housing 1 through the air outlet 8. In this way, an air flow cycle can be formed to play the role of filtering and removing dust from the air inside the workshop;

[0029] And at this time, this device is provided with an expansion interface 9. The dust suction pipe 12 can be quickly and interference-fitted through the expansion interface 9, so that the dust suction pipe 12 can be connected at any time according to needs. In this way, when there are workers cutting and welding in the workshop, the dust suction pipe 12 can be used to mainly adsorb the dust generated during the work in the working area, so as to improve the effect of adsorption and dust removal; the unused expansion mechanism can be sealed by the butterfly plate 13 according to needs;

[0030] And when this device is in use, vibration is generated by the vibration motor 23. The vibration can drive the movable frame 6, so that the movable frame 6 and the filter tube 7 swing up and down continuously.
