Description

Technical Field

[0001] This utility model relates to the field of hot-dip galvanized guardrail production technology, specifically to an air purification device for hot-dip galvanized guardrail production. Background Technology

[0002] The production process of hot-dip galvanized guardrails generates a large amount of waste gas. If this waste gas is discharged directly into the atmosphere without treatment, it will cause serious pollution to the environment. Therefore, air purification devices used in the production of hot-dip galvanized guardrails are important equipment to ensure a clean production environment and compliance with environmental protection standards. They mainly use high-energy ultraviolet light beams in photocatalytic oxidation devices to irradiate the waste gas, causing the molecular chains of harmful gases to degrade and transform into harmless substances.

[0003] For example, patent application number 202210427291.7 published on the China Patent Network, entitled "A Multifunctional Medical Air Purification Device," includes a working chassis with a ventilation channel snapped onto its side end face, and a transducer mechanism is assembled between the ventilation channel and the working chassis. In this invention, the heat energy released by the waterproof motor is used for heating, and the resulting liquid is injected into the distributor via a pipe. Finally, it is sprayed onto the air purification plate through atomizing nozzles on the distributor. The heated liquid can better dissolve bacteria in the air, and simultaneously provides sound insulation for the waterproof motor, effectively reducing the noise level released by the entire medical air purification device during use. This facilitates a more suitable environment for patients and medical staff in the medical room and also provides good heat dissipation for the waterproof motor, ensuring its long-term effective operation and the stability of the medical air purification device during extended operation.

[0004] However, existing purification equipment mainly uses fans to draw waste gas into a channel containing photocatalysts for purification. Since hot-dip galvanized guardrails are relatively long, equipment placed directly on top of the guardrails during processing will draw in surrounding air, resulting in reduced air pressure on the side of the equipment facing the hot-dip galvanized guardrails and affecting the waste gas collection effect.

[0005] Therefore, it is necessary to redesign and modify the air purification device used in the production of hot-dip galvanized guardrails. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide an air purification device for the production of hot-dip galvanized guardrails. This device has the advantage of increasing the wind pressure in a specific collection direction of exhaust gas. It solves the problem that existing purification equipment mainly uses a fan to extract exhaust gas into a channel containing a photocatalyst for purification. However, hot-dip galvanized guardrails are relatively long, and the equipment placed directly on top of the guardrail during processing will draw in surrounding air, resulting in a decrease in wind pressure on the side of the equipment facing the hot-dip galvanized guardrail, which affects the exhaust gas collection effect.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an air purification device for hot-dip galvanized guardrail production, including a fan;

[0008] A photocatalyst channel connected to the input end of the fan;

[0009] Connecting blocks are fixedly connected to the left and right sides of the photocatalytic channel. A guide plate is movably connected to the surface of the connecting block via a pin. The guide plate can swing on the surface of the connecting block via the pin and adjust the bottom spacing. A transmission structure is provided at the top of the photocatalytic channel, which can drive the guide plate to swing.

[0010] In a preferred embodiment of this invention, the transmission structure includes a connecting frame fixedly connected to the top of the photocatalyst channel. A bidirectional reciprocating screw is movably connected inside the connecting frame via bearings. Both sides of the surface of the bidirectional reciprocating screw are threaded with threaded sleeves. A sleeve plate is fixedly connected to the front of the guide plate. The side of the sleeve plate away from the guide plate extends to the front of the threaded sleeve. A sliding rod is fixedly connected to the front of the threaded sleeve. The side of the sliding rod away from the threaded sleeve extends into the interior of the sleeve plate. The sleeve plate and the sliding rod are slidably connected.

[0011] As a preferred embodiment of this invention, both sides of the surface of the bidirectional reciprocating screw are threaded with limit rings, and the limit rings are located inside the screw sleeve.

[0012] As a preferred embodiment of this invention, a limiting groove is formed on the surface of the connecting frame, and a limiting rod located inside the limiting groove is fixedly connected to the surface of the threaded sleeve.

[0013] As a preferred embodiment of this utility model, the drive end of the fan is provided with a drive motor, and the output end of the drive motor and one end of the bidirectional reciprocating screw are both fixedly connected to pulleys, with belts sleeved on the surface of the pulleys.

[0014] As a preferred embodiment of this invention, a bracket is fixedly connected to the surface of the bidirectional reciprocating screw, and a buffer wheel located inside the belt is movably connected to the surface of the bracket via a bearing.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model achieves control over the exhaust range of the bottom exhaust port by setting up a combination of a fan and a photocatalytic channel. The guide plate, which is movably connected by a pin on the connecting block, can flexibly adjust the bottom spacing, thereby adjusting the exhaust range as needed. This not only improves the air purification efficiency but also enhances the adaptability and flexibility of the device.

[0017] 2. This utility model uses the cooperation of a bidirectional reciprocating screw and a screw sleeve to drive the swing of the guide plate through the reciprocating movement of the screw sleeve. It is not only simple and compact in structure, but also ensures that the guide plate swings stably and accurately, thereby achieving precise control of the exhaust range. In addition, the sliding connection design of the slide rod and the sleeve plate also increases the stability and durability of the structure.

[0018] 3. This utility model, through the design of a limiting ring for threaded connection on the surface of the bidirectional reciprocating screw, plays a limiting role in the screw sleeve, preventing the screw sleeve from falling off or misaligning during movement. This not only improves the safety of the device but also ensures the stability and reliability of the transmission structure.

[0019] 4. By opening a limiting groove on the surface of the connecting frame and fixing a limiting rod on the surface of the threaded sleeve, this utility model further restricts the movement range of the threaded sleeve, ensuring that the threaded sleeve can only move on a specified path. This not only improves the accuracy of the transmission structure but also enhances the stability and durability of the device.

[0020] 5. This utility model provides a power source for the rotation of the bidirectional reciprocating screw by introducing a drive motor. The synchronous rotation of the motor and the screw is achieved through belt drive, which not only simplifies the transmission structure and reduces energy consumption, but also improves transmission efficiency. At the same time, belt drive also has a certain buffering and shock absorption effect, which helps to protect the transmission components from damage.

[0021] 6. This utility model, by fixing a bracket to the surface of a bidirectional reciprocating screw and movably connecting a buffer wheel to the bracket via a bearing, provides support and buffer for the belt, which not only reduces the friction and wear of the belt during transmission but also improves the smoothness and reliability of the transmission.

[0027] 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.

[0028] like Figures 1 to 4 As shown, the present invention provides an air purification device for hot-dip galvanized guardrail production, including a fan 1;

[0029] Photocatalyst channel 2 connected to the input end of fan 1;

[0030] Connecting blocks 3 are fixedly connected to the left and right sides of the photocatalytic channel 2. A guide plate 4 is movably connected to the surface of the connecting block 3 via a pin. The guide plate 4 can swing on the surface of the connecting block 3 via the pin and adjust the bottom spacing. A transmission structure 5 is provided at the top of the photocatalytic channel 2. The transmission structure 5 can drive the guide plate 4 to swing.

[0031] refer to Figure 4 The transmission structure 5 includes a connecting frame 6 fixedly connected to the top of the photocatalyst channel 2. A bidirectional reciprocating screw 7 is movably connected inside the connecting frame 6 via a bearing. Both sides of the surface of the bidirectional reciprocating screw 7 are threaded with a screw sleeve 8. A sleeve plate 9 is fixedly connected to the front of the guide plate 4. The side of the sleeve plate 9 away from the guide plate 4 extends to the front of the screw sleeve 8. A slide rod 10 is fixedly connected to the front of the screw sleeve 8. The side of the slide rod 10 away from the screw sleeve 8 extends to the inside of the sleeve plate 9. The sleeve plate 9 and the slide rod 10 are slidably connected.

[0032] As a technical optimization of this utility model, the guide plate 4 is driven to swing by the reciprocating movement of the screw 8 through the cooperation of the bidirectional reciprocating screw 7 and the screw sleeve 8. This not only makes the structure simple and compact, but also ensures that the guide plate 4 swings stably and accurately, thereby achieving precise control of the exhaust range. In addition, the sliding connection design of the slide rod 10 and the sleeve plate 9 also increases the stability and durability of the structure.

[0033] refer to Figure 4 Both sides of the surface of the bidirectional reciprocating screw 7 are threaded with limit rings 11, which are located inside the screw sleeve 8.

[0034] As a technical optimization of this utility model, the design of the limiting ring 11 connected to the threaded surface of the bidirectional reciprocating screw 7 plays a limiting role in the screw sleeve 8, preventing the screw sleeve 8 from falling off or misaligning during movement. This not only improves the safety of the device, but also ensures the stability and reliability of the transmission structure 5.

[0035] refer to Figure 4 A limiting groove 12 is provided on the surface of the connecting frame 6, and a limiting rod 13 located inside the limiting groove 12 is fixedly connected to the surface of the screw sleeve 8.

[0036] As a technical optimization of this utility model, by opening a limiting groove 12 on the surface of the connecting frame 6 and fixing a limiting rod 13 on the surface of the threaded sleeve 8, the movement range of the threaded sleeve 8 is further limited, ensuring that the threaded sleeve 8 can only move on the specified path. This not only improves the accuracy of the transmission structure 5, but also enhances the stability and durability of the device.

[0037] refer to Figure 1 The drive end of the fan 1 is equipped with a drive motor 14. The output end of the drive motor 14 and one end of the bidirectional reciprocating screw 7 are both fixedly connected to pulleys 15. A belt 16 is sleeved on the surface of the pulley 15.

[0038] As a technical optimization of this utility model, the introduction of the transmission motor 14 provides a power source for the rotation of the bidirectional reciprocating screw 7. The synchronous rotation of the motor and the screw is achieved through the belt 16 transmission, which not only simplifies the transmission structure 5 and reduces energy consumption, but also improves transmission efficiency. At the same time, the belt 16 transmission also has a certain buffering and shock absorption effect, which helps to protect the transmission components from damage.

[0039] refer to Figure 1 A bracket 17 is fixedly connected to the surface of the bidirectional reciprocating screw 7, and a buffer wheel 18 located inside the belt 16 is movably connected to the surface of the bracket 17 via a bearing.

[0040] As a technical optimization of this utility model, by fixing the bracket 17 to the surface of the bidirectional reciprocating screw 7 and movably connecting the buffer wheel 18 to the bracket 17 via bearings, the belt 16 is supported and buffered, which not only reduces the friction and wear of the belt 16 during transmission, but also improves the smoothness and reliability of transmission.

[0041] The working principle and usage process of this utility model are as follows: The drive motor 14 starts and controls the fan 1, which begins to draw air from the bottom exhaust port. The output end of the drive motor 14 drives the bidirectional reciprocating screw 7 to rotate via the belt 16. The rotation of the bidirectional reciprocating screw 7 causes the threaded sleeve 8 on its surface to reciprocate along the thread direction of the screw under the constraint of the limiting ring 11 and the limiting rod 13. The movement of the threaded sleeve 8 causes the sliding rod 10 and the sleeve plate 9, which are fixedly connected to its front side, to move together. Since the side of the sleeve plate 9 away from the guide plate 4 extends to the front side of the threaded sleeve 8, and the sleeve plate 9 and the sliding rod 10... The sliding connection allows the movement of the slide bar 10 to push or pull the sleeve plate 9, which in turn causes the guide plate 4 to swing on the surface of the connecting block 3 via the pin. As the bidirectional reciprocating screw 7 continues to rotate, the screw sleeve 8 causes the guide plate 4 to swing continuously, thereby adjusting the exhaust range of the bottom exhaust port of the photocatalytic channel 2. In this way, the intensity and range of the exhaust can be controlled as needed to achieve the best air purification effect. At the same time, the continuously swinging guide plate 4 can disturb the airflow, making it easier for the smoke generated during the production of the guardrail to quickly mix with the surrounding environment and avoid the occurrence of a high-concentration environment.

[0042] In summary, this air purification device for hot-dip galvanized guardrail production, through the combination of fan 1 and photocatalytic channel 2, achieves control over the exhaust range of the bottom exhaust port. The guide plate 4, which is movably connected by the pin on the connecting block 3, can flexibly adjust the bottom spacing, thereby adjusting the exhaust range as needed. This not only improves air purification efficiency but also enhances the adaptability and flexibility of the device.
