Description

Technical Field

[0001] This utility model relates to the field of hazardous gas treatment technology, specifically a hazardous gas treatment device for metal spraying equipment. Background Technology

[0002] Metal spraying equipment generates various harmful gases and paint mist during operation. These exhaust gases contain harmful substances such as grease, particulate matter, and odors emitted by diluents, including benzene, toluene, and xylene. These substances not only pollute the production environment and affect workers' health but may also pose a threat to the health of surrounding residents. To effectively reduce the emission of these harmful substances, protect the environment, safeguard workers' health, and improve production efficiency, metal spraying equipment must be equipped with hazardous gas treatment devices.

[0003] Existing hazardous gas treatment devices for metal spraying equipment are prone to clogging by fine airborne particles during prolonged operation. As operating time accumulates, these particles weaken the filtration effect and obstruct airflow, impacting the overall system efficiency. When the filter becomes severely clogged, operators must stop operation to remove and clean it – a tedious and time-consuming process that severely affects production line continuity and efficiency. Frequent cleaning increases labor costs and can lead to complete clogging if not done promptly, further exacerbating airflow problems and significantly reducing the device's effectiveness. Therefore, we propose a hazardous gas treatment device for metal spraying equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a hazardous gas treatment device for metal spraying equipment, to solve the problem mentioned in the background art that the filter screen inside the existing hazardous gas treatment device for metal spraying equipment is easily clogged by tiny particles in the air during long-term operation. As the operating time accumulates, these particles continuously accumulate on the filter screen, which not only gradually weakens the filtration effect, but also leads to obstruction of the airflow channel, affecting the operating efficiency of the entire treatment system. Whenever the filter screen becomes clogged to a certain extent, the staff has to stop the operation of the equipment, remove and clean the filter screen. This maintenance process is cumbersome and time-consuming, which seriously affects the continuity and efficiency of the production line. The frequent need for filter screen cleaning not only increases labor costs, but may also lead to complete clogging of the particulate filter screen due to untimely maintenance, further aggravating the problem of obstructed airflow, thus greatly reducing the actual effectiveness of the hazardous gas treatment device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a harmful gas treatment device for metal spraying equipment, comprising a housing, a drive motor fixedly installed at the center of the top of the housing, a fan blade at the lower end of the drive motor, an air filter at the lower end of the fan blade, a reciprocating screw at the lower end of the air filter, a screw nut threadedly connected to the center of the surface of the reciprocating screw, a reduction motor fixedly installed at the bottom of one side of the outer wall of the housing, a driven gear fixedly installed at one side of the surface of the screw nut, a driving gear meshing with the top of the driven gear, a connecting rod fixedly connected to the center of the bottom of the screw nut, a dust filter frame fixedly installed at the bottom of the housing, a dust filter screen fixedly installed at the center of the bottom of the dust filter frame, a transverse groove opened at the rear end of the top of the dust filter frame, continuous folding plates fixedly connected to both sides of the transverse groove, a connecting block provided at the center of the bottom of the dust filter screen, and a brush fixedly installed on the top of the connecting block.

[0006] Compared with the prior art, the beneficial effects of this utility model are:

[0007] This hazardous gas treatment device for metal spraying equipment achieves automatic cleaning of the dust filter screen through the design of a reciprocating screw, screw nut, geared motor, drive gear, driven gear, connecting rod, connecting block, and brush. During continuous operation, the geared motor drives the drive gear to rotate, which in turn drives the driven gear and screw nut to reciprocate linearly along the reciprocating screw. This motion is transmitted to the connecting block and brush through the connecting rod, allowing the brush to continuously scrub the bottom of the dust filter screen, effectively preventing the accumulation and clogging of particles, significantly extending the cleaning cycle of the dust filter screen, and reducing the frequency and cost of manual maintenance. The design of the transverse groove and continuous folding plate allows the continuous folding plate on both sides to dynamically fold and unfold as the connecting rod reciprocates inside the transverse groove. The continuous folding plate forms a dynamic sealing barrier, effectively blocking particles from passing through the transverse groove, improving the practicality of the hazardous gas treatment device and meeting market demands.

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.

[0014] Please see Figure 1-4 This utility model provides a technical solution: a harmful gas treatment device for metal spraying equipment, including a housing 1. A drive motor 2 is fixedly installed at the center of the top of the housing 1. A fan blade 3 is provided at the lower end of the drive motor 2. An air filter screen 5 is provided at the lower end of the fan blade 3. A reciprocating screw 6 is provided at the lower end of the air filter screen 5. A screw nut 7 is threadedly connected to the center of the surface of the reciprocating screw 6. A reduction motor 8 is fixedly installed at the bottom of one side of the outer wall of the housing 1. A driven gear 10 is fixedly installed at one side of the surface of the screw nut 7. A drive gear 9 is meshed at the top of the driven gear 10. A connecting rod 11 is fixedly connected to the center of the bottom of the screw nut 7. A dust filter rack 13 is fixedly installed at the bottom of the housing 1. A dust filter screen 19 is fixedly installed at the center of the bottom of the dust filter rack 13. A horizontal groove 14 is opened at the rear end of the top of the dust filter rack 13. Continuous folding plates 15 are fixedly connected to both sides of the horizontal groove 14. A connecting block 16 is provided at the center of the bottom of the dust filter screen 19. A brush 17 is fixedly installed at the top of the connecting block 16.

[0015] The drive motor 2 is fixedly connected to the drive shaft through its bottom output end. The bottom of the drive shaft is fixedly connected to the center of the top of the fan blade 3, providing a power source for the harmful gas treatment device, driving the fan blade 3 to rotate, thereby generating airflow, so that the air containing harmful gases can be drawn into the device for treatment.

[0016] The inner wall of the housing 1 is fixedly installed with a bracket 4 at each end corresponding to the air filter 5. The two sides of the air filter 5 pass through the interior of the two brackets 4 and are engaged with the inner wall of the brackets 4, which facilitates the installation and removal of the air filter 5, and makes it easy for staff to clean or replace it, ensuring the filtration effect.

[0017] The two ends of the reciprocating screw 6 are movably connected to bearings fixedly installed on both sides of the inner wall of the housing 1 near the bottom. The geared motor 8 is fixedly connected to a drive shaft through its output end on one side. One side of the drive shaft extends to the outside of the housing 1 and is fixedly connected to the center of one side of the drive gear 9. The drive gear 9 is driven to rotate by the geared motor 8, which in turn drives the driven gear 10 and the screw nut 7 to move on the reciprocating screw 6, thereby realizing the automatic cleaning function of the dust filter 19.

[0018] A guide rod 12 is fixedly installed on the inner wall of the housing 1 corresponding to the bottom of the lead screw nut 7. One end of the guide rod 12 extends through to the outside of the connecting rod 11 and is fixedly connected to the other side of the inner wall of the housing 1, providing a stable moving track for the connecting rod 11, ensuring that it can move back and forth smoothly in the transverse groove 14, and increasing the stability of the structure.

[0019] The upper end of the brush 17 contacts the bottom of the dust filter 19. The bottom of the connecting rod 11 extends through the outside of the transverse groove 14 and is fixedly connected to the rear end of the connecting block 16. The opposite sides of the two continuous folding plates 15 are fixedly connected to the two sides of the outer wall of the connecting rod 11. By reciprocating the movement of the connecting rod 11, the brush 17 is driven to clean the dust filter 19. At the same time, the continuous folding plates 15 form a dynamic barrier during the movement to prevent particles from entering through the transverse groove 14.

[0020] The top of the housing 1 has exhaust ports 20 on both sides to discharge the filtered and purified gas. The bottom of the housing 1 has an air inlet pipe 18 fixedly connected to the center for gas entry. The top of the housing 1 has mounting brackets 21 fixedly connected on both sides for fixing the device to a designated position on the spraying equipment.

[0021] Working principle: After the device is started, the drive motor 2 drives the drive shaft to rotate through its bottom output end, which in turn drives the fan blades 3 to rotate, generating a strong airflow. This airflow draws air containing harmful gases into the device through the air intake pipe 18. The drawn-in air first passes through the dust filter 19, which effectively blocks large particles in the air, ensuring the efficiency and quality of subsequent processing. The air that has passed through the initial filtration continues to flow upward. At this time, the reduction motor 8 starts to work, driving the drive gear 9 to rotate through its output end. The drive gear 9 meshes with the driven gear 10, driving the lead screw nut 7 to perform reciprocating linear motion on the reciprocating lead screw 6. The movement of 7 is transmitted to the connecting block 16 and the brush 17 through the connecting rod 11, so that the brush 17 can brush back and forth at the bottom of the dust filter 19, effectively removing the particles accumulated on the dust filter 19, keeping the dust filter 19 unobstructed and maintaining its filtration efficiency. At the same time, the reciprocating movement of the connecting rod 11 in the transverse groove 14 also drives the folding and unfolding of the continuous folding plate 15. During the movement, the continuous folding plate 15 closely fits the edge of the transverse groove 14, forming a dynamic sealing barrier, effectively preventing particles from entering the device through the transverse groove 14. Finally, the purified air is discharged through the exhaust port 20 at the top of the housing 1, completing the entire treatment process.

[0022] In summary, this hazardous gas treatment device for metal spraying equipment, through the design of a reciprocating screw 6, screw nut 7, geared motor 8, driving gear 9, driven gear 10, connecting rod 11, connecting block 16, and brush 17, achieves the automatic cleaning function of the dust filter 19. During continuous operation, the geared motor 8 drives the driving gear 9 to rotate, which in turn drives the driven gear 10 and screw nut 7 to reciprocate linearly along the reciprocating screw 6 through meshing. This motion is transmitted to the connecting block 16 and brush 17 through the connecting rod 11, enabling the brush 17 to... Continuous back-and-forth brushing at the bottom of the dust filter 19 effectively prevents the accumulation and clogging of particulate matter, significantly extends the cleaning cycle of the dust filter 19, and reduces the frequency and cost of manual maintenance. The design of the transverse groove 14 and the continuous folding plate 15 allows the connecting rod 11 to move back and forth inside the transverse groove 14, simultaneously pulling the continuous folding plates 15 on both sides to dynamically fold and unfold. The continuous folding plate 15 forms a dynamic sealing barrier, effectively blocking particulate matter from passing through the transverse groove 14, improving the practicality of the harmful gas treatment device and meeting market demands.
