Description

Technical Field

[0001] This utility model relates to the field of ventilation equipment technology, specifically a factory ventilation and air exchange device. Background Technology

[0002] As we all know, with respiratory infectious diseases becoming an increasingly significant threat to people's daily work and life, increasing ventilation in local environments is an effective way to prevent the spread of respiratory infectious diseases. In the current use of existing factory buildings, general factory buildings adopt double-sloped roofs with materials such as profiled steel sheets. Factory buildings are generally large in area, and there are often situations where certain workstations require increased ventilation.

[0003] Currently, some existing ventilation devices use fans installed in ventilation ducts to ventilate the factory. However, if the ventilation ducts are not filtered and protected during use, impurities such as leaves and plastics can easily enter the ventilation ducts and then enter the factory, causing pollution inside the factory. In response to the above situation, we will carry out technological innovation based on the existing devices. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The ventilation and air exchange device in this factory uses a brush to clean the filter screen, which can keep the filter screen pores clear to a certain extent. This effectively reduces the adhesion of impurities such as leaves and plastics to the filter screen, preventing clogging of the pores, affecting the air intake of the ventilation openings, and causing the ventilation and air exchange effect of the factory to deteriorate.

[0015] 2. The ventilation system in this factory allows workers to easily replace or repair the filter frame by pulling out the handle. This reduces damage to the filter screen and prevents impurities such as leaves and plastic from entering the ventilation opening, while also minimizing the time required for filter replacement or repair.

A filter frame 3 is slidably connected inside the mounting groove 2, and a filter screen is provided on the filter frame 3. A handle is provided on the top of the filter frame 3, and a fixing groove 12 is provided on one side of the filter frame 3. The filter screen can prevent external impurities such as leaves and plastic from entering the ventilation opening 7. A first protective shell 4 is fixedly connected to the right side of the box 1. A forward and reverse motor 8 is provided inside the first protective shell 4. A power supply, wires, controller and microcomputer structure are provided to match the forward and reverse motor 8. Since the forward and reverse motor 8 is not a major structure, it will not be described in detail. A transmission groove 9 is provided inside the box 1, and a power adjustment device is provided inside the transmission groove 9.

[0023] Please refer to Figure 3 The power adjustment device includes a transmission block 11, which is slidably connected to the inside of the transmission groove 9. A cleaning plate 5 is fixedly connected to the bottom of the transmission block 11. A brush is provided on the side of the cleaning plate 5 near the filter screen. The filter screen can be cleaned by the brush. A threaded rod 10 is rotatably connected inside the transmission groove 9. The surface of the threaded rod 10 is threadedly connected to the inside of the transmission block 11. By rotating the threaded rod 10, the threaded rod 10 can drive the transmission block 11 to slide.

[0024] Please refer to Figure 3 The output end of the forward and reverse motor 8 rotates through the transmission groove 9 and extends into it. The output end of the forward and reverse motor 8 is fixedly connected to a rotating shaft through a coupling. The outer wall of the rotating shaft is fixedly connected to the right side of the threaded rod 10. The output end of the forward and reverse motor 8 can drive the threaded rod 10 to rotate in both directions through the rotating shaft.

[0025] Please refer to Figure 3 A limit rod 6 is fixedly connected to the inner wall of the vent 7, and the surface of the limit rod 6 is slidably connected to the inside of the cleaning plate 5.

[0026] The staff starts the forward and reverse motor 8 through the controller and microcomputer structure. The output end of the forward and reverse motor 8 drives the threaded rod 10 to rotate forward and backward through the rotating shaft. The threaded rod 10 drives the transmission block 11 to reciprocate. The transmission block 11 drives the cleaning plate 5 to reciprocate and clean the filter screen through the brush. The brush cleaning of the filter screen can keep the filter screen mesh open to a certain extent, effectively reducing the adhesion of impurities such as leaves and plastics to the filter screen, which can cause the mesh to become blocked, affect the air intake of the ventilation opening 7, and reduce the ventilation effect of the factory.

[0027] Please refer to Figure 4 A support plate 16 is fixedly connected to the inner wall of the ventilation opening 4. A second protective shell 17 is fixedly connected to one side of the support plate 16. A motor 18 is installed inside the second protective shell 17. The motor 18 is configured in the same way as the forward and reverse motor 8.

[0028] Please refer to Figure 4 The output end of motor 18 rotates through the support plate 16 and extends to its outside. The output end of motor 18 is fixedly connected to a rotating shaft through a coupling. A rotating rod 19 is fixedly connected to the outer wall of the rotating shaft. A fan 20 is fixedly connected to the end of the rotating rod 19 away from motor 18. The output end of motor 18 drives the rotating rod 19 to rotate through the rotating shaft. The rotating rod 19 can drive the fan to rotate.

[0029] The interior of the housing 1 has a sliding groove 13, and a fixing block 14 is slidably connected inside the sliding groove 13. The top of the fixing block 14 is provided with a protrusion, and the fixing block 14 is inserted into the interior of the fixing groove 12.

[0030] Please refer to Figure 4 A spring 15 is fixedly connected to the right side of the fixed block 14. The end of the spring 15 away from the fixed block 14 is fixedly connected to the inner wall of the sliding groove 13. The spring 15 can be compressed and reset by sliding the fixed block 14.

[0031] By moving the protrusion, the fixing block 14 can slide to the right, and the spring 15 is compressed. The fixing block 14 slides out of the fixing groove 12 and is released from fixation. Then, the staff can pull the filter frame 3 upward with the handle, which makes it convenient for the staff to replace or repair the filter frame 3 in a timely manner, reducing the damage to the filter screen on the filter frame 3 and preventing impurities such as leaves and plastic from entering the vent. It also effectively reduces the time required for replacing or repairing the filter frame.

[0032] Working principle: For this type of factory ventilation and air exchange device, the staff first installs the box 1 on the factory wall, and starts the motor 18 through the external device. The output end of the motor 18 drives the rotating rod 19 to rotate through the rotating shaft. The rotating rod 19 drives the fan to rotate, which can ventilate the inside of the factory.

[0033] When it is necessary to clean the filter screen on the filter frame 3, the operator starts the forward and reverse motor 8 through the external control device. The output end of the forward and reverse motor 8 drives the threaded rod 10 to rotate through the rotating shaft. The threaded rod 10 drives the transmission block 11 to reciprocate. The transmission block 11 drives the cleaning plate 5 to reciprocate. The cleaning plate 5 cleans the filter screen with a brush.
