Description

Technical Field

[0001] The utility model relates to the technical field of workshop ventilation, in particular to a ventilation and exhaust device for manufacturing a rubber and plastic product workshop. Background Art

[0002] Workshop ventilation and exhaust are crucial to maintaining a good working environment and protecting workers' health. During the production process, workshops may produce various harmful gases (such as welding fumes, volatile gases from chemicals, etc.) and dust. Ventilation and exhaust systems can promptly discharge these harmful substances to the outdoors, reduce their concentration in the workshop, and reduce harm to workers' health. Ventilation and exhaust can continuously update the air in the workshop, improve air quality, provide workers with a comfortable and healthy working environment, and improve work efficiency.

[0003] The utility model with application number 202321251263.0 discloses a ventilation device for a production workshop, which is provided with a first spring and a resisting mechanism. When the mounting plate is fully retracted into the ventilation pipe, the first spring is in a squeezed state, and the two limit blocks resist the outer side of the connecting frame. When the activated carbon layer and the HEPA filter layer need to be replaced, the limit block only needs to be pulled into the hollow block, and then the hollow block is rotated 90 degrees so that the limit block no longer contacts the connecting frame. Under the rebound action of the first spring, the mounting plate and the connecting frame automatically pop out of the ventilation pipe, so that a new activated carbon layer and HEPA filter layer can be quickly replaced. By opening a groove on the mounting plate, the groove limits the activated carbon layer and the HEPA filter layer, so that the activated carbon layer and the HEPA filter layer can be quickly installed and removed from the mounting plate.

[0004] However, the position of the ventilation duct in the above-mentioned production workshop ventilation device is fixed, and the space in the production workshop is large, which limits the ventilation and exhaust range. Generally, harmful gases are easily generated near the production equipment during product processing, and ventilation cannot be quickly guided. The ventilation duct in the above-mentioned production workshop ventilation device is relatively short, and the exhaust fan and the filter element only play an air filtering role, and the irritating gases generated by the workshop production cannot be filtered and discharged. Therefore, the utility model proposes a ventilation and exhaust device for rubber and plastic product workshop manufacturing to solve the problems existing in the prior art. Utility Model Content

DETAILED DESCRIPTION

[0018] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0019] according to Figure 1 、 Figure 2 、 Figure 3 As shown, this embodiment provides a ventilation and exhaust device for manufacturing rubber and plastic products workshops, including a ventilation pipe 1, a movable stretching mechanism, a ventilation mechanism and a filtering mechanism. The movable stretching mechanism includes a movable bracket 2, a handle 3, a universal locking wheel 4, a stretching bellows 5 and an air outlet pipe 6. The ventilation pipe 1 is fixedly provided with a movable bracket 2, and a handle 3 is fixedly provided on the other side of the movable bracket 2. The four corners of the bottom of the movable bracket 2 are matched and fixed with universal locking wheels 4. One side of the ventilation pipe 1 is connected and fixed with a stretching bellows 5, and one side of the stretching bellows 5 is connected and fixed with an air outlet pipe 6. A clamping mechanism is provided below the air outlet pipe 6. A filtering mechanism is provided on one side of the ventilation pipe 1, and a ventilation mechanism is provided on the other side of the ventilation pipe 1. When production is carried out in the rubber and plastic products workshop, the movable bracket 2 is pushed by the handle 3, and the universal locking wheel 4 drives the movable bracket 2 and the ventilation pipe 1 to move to the side of the production equipment, so that the position of the ventilation pipe 1 can be adjusted according to production needs, so as to quickly filter and discharge the irritating gas generated by production.

[0020] The clamping mechanism includes a fixed plate 7, a slide rail 8, a clamping plate 9, a threaded hole 10, a screw 11 and a bearing seat 12. The fixed plate 7 is symmetrically fixed to the bottom of the air outlet 6, and a slide rail 8 is fixed in the middle of the bottom of the air outlet 6. A clamping plate 9 is slidably fitted under the slide rail 8. A threaded hole 10 is provided on the fixed plate 7 on the other side, and a screw 11 is fitted with a threaded inner hole 10. A bearing seat 12 is fixed to the other side of the clamping plate 9. The fixed plate 7 corresponds to the clamping plate 9 in position, and one side of the screw 11 is connected to the bearing seat 12 for rotation. Before ventilation, the air outlet 6 is placed on the workshop window, and the screw 11 is rotated to cooperate with the threaded hole 10 to push the clamping plate 9 to move along the slide rail 8. The air outlet duct 6 is clamped on the workshop window by cooperating with the clamping plate 9 and the fixed plate 7 for convenient exhaust.

[0021] The filter mechanism includes a slide 13, a spring 14, a lifting plate 15, a filter element 16 and a block 17. A slide 13 is symmetrically arranged on one side of the ventilation pipe 1. The slide 13 is arranged in multiple groups. A spring 14 is fixedly provided at the bottom of the slide 13. A lifting plate 15 is fixed above the spring 14. A filter element 16 is inserted between the slides 13. A blocking block 17 is provided on one side of the ventilation pipe 1 to rotate. The blocking block 17 has multiple groups. The blocking block 17 corresponds to the position of the slide 13. When the air in the ventilation pipe 1 flows, the air is filtered by the filter element 16, effectively preventing the irritating gas generated in the production from being directly discharged. When the filter element 16 needs to be replaced, the blocking block 17 is rotated so that the spring 14 rebounds and drives the lifting block to push the filter element 16 out of the ventilation pipe 1. After the new filter element 16 is reinserted along the slide 13, the lifting plate 15 and the spring 14 are squeezed, and then the blocking block 17 is turned back to support the filter element 16 from above for easy replacement.

[0022] The ventilation mechanism includes a protective grille 18, a connecting frame 19, a motor 20 and a fan 21. The protective grille 18 is fixed to the end of the other side of the ventilation pipe 1, and a connecting frame 19 is fixed to the other side of the ventilation pipe 1. A motor 20 is fixed on one side of the connecting frame 19, and a fan 21 is fixed on the other side of the connecting frame 19. The protective grilles 18 are fixed in an staggered manner, and the output end of the motor 20 is driven and connected to the fan 21. When ventilation and exhaust are performed, the motor 20 starts to drive the fan 21 to rotate for exhaust, which is convenient for rapid exhaust and ventilation of designated areas in the workshop.

[0023] When the ventilation and exhaust device for manufacturing rubber and plastic products workshop is used, the movable bracket is pushed by the handle, and the universal locking wheel pushes the movable bracket and the ventilation pipe to move next to the production equipment in the workshop. After the outlet pipe is clamped on the workshop window, the screw is turned to push the clamping plate to slide along the slide rail and clamp it with the fixed plate. The motor starts to drive the fan to rotate for exhaust. The air is drawn into the ventilation pipe and filtered through the filter element. It is then guided by the stretched bellows and discharged from the outlet pipe to achieve exhaust ventilation of the designated area in the workshop. When the filter element needs to be replaced, the clamping block is turned, and the spring rebound drives the lifting plate to rise to push out the filter element for replacement. The replaced filter element is reinserted into the ventilation pipe along the slide groove and then turned back to the clamping block for fixation.
