Technical Field

[0001] This utility model belongs to the field of non-powered fan technology, and in particular, it is a non-powered fan with dust removal function. Background Technology

[0002] A non-powered fan is a device that uses natural wind speed to drive the turbine of the fan and utilizes the principle of indoor and outdoor air convection to accelerate and transform any parallel airflow into a vertical airflow from bottom to top, thereby improving indoor ventilation.

[0003] Existing non-powered fans are all installed on the roof of factories or greenhouses and exposed to the outside world. Therefore, when the non-powered fans are working, they will directly suck dust from the air into the factory or greenhouse and cause pollution to the interior. Therefore, there is an urgent need for a non-powered fan with dust removal function to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a non-powered fan with dust removal function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a non-powered fan with dust removal function, comprising a mounting plate for installing the non-powered fan and a non-powered fan, wherein an air inlet duct is fixedly connected to the top surface of the mounting plate, and a fixing plate is fixedly connected to the top surface of the air inlet duct and the lower end of the non-powered fan, and the fixing plate fixedly connected between the lower end of the non-powered fan and the top surface of the air inlet duct is fixedly connected by bolts.

[0006] Two arc-shaped holes are symmetrically opened on one side of the air inlet duct. An arc-shaped block is snapped into the inside of each arc-shaped hole. A ring is fixedly connected to the inner wall of the arc-shaped block. An annular groove is opened on the inner wall of the air inlet duct and is connected to the arc-shaped hole. The ring slides into the inside of the annular groove. A dust removal screen is fixedly connected to the inside of the ring and slides into the inside of the air inlet duct. A handle is fixedly connected to the outer side of the arc-shaped block.

[0007] Preferably, both the top and bottom surfaces of the ring are fixedly connected to sealing rings, and the outer walls of the sealing rings are respectively sealed and fitted to the inner wall of the annular groove.

[0008] Preferably, the top and bottom surfaces of the arc-shaped block are fixedly connected with sealing gaskets, and the sealing gaskets are slidably attached to the inner wall of the arc-shaped hole.

[0009] Preferably, the bottom surface of the arc-shaped block is provided with a mounting groove, a spring is fixedly connected in the mounting groove, and a locking block is fixedly connected to the end of the spring.

[0010] Preferably, the lower end of the card block slides to the bottom of the arc-shaped block, and a card groove is provided at the lower end of the inner wall of the arc-shaped hole.

[0011] Preferably, a lever is fixedly connected to one end of the locking block, and the end of the lever away from the locking block slides to the outside of the arc-shaped block.

[0014] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0015] This non-powered fan with dust removal function draws air into the air inlet duct when it is operating. Because the air inlet duct is equipped with a circular ring and a dust filter, the air entering the duct is filtered by the dust filter, preventing dust from entering the factory or greenhouse. When too much dust accumulates on the surface of the dust filter, the curved block is pulled outwards by hand, simultaneously pulling the circular ring and dust filter out of the air inlet duct, thus cleaning the dust from the top surface of the dust filter. Compared with existing technologies, this device effectively filters dust from the air drawn in by the non-powered fan, preventing pollution inside the factory or greenhouse.

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0026] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0027] like Figures 1 to 5 The main structure of a dust removal fan is a mounting plate 1 for installing the fan and a fan 3. The fan 3 is automatically rotating and converts horizontally moving air into a vertical direction.

[0028] An air inlet duct 2 is fixedly connected to the top surface of the mounting plate 1. A mounting plate 8 is fixedly connected to the top surface of the air inlet duct 2 and the lower end of the non-powered fan 3. The mounting plate 8 fixedly connected between the lower end of the non-powered fan 3 and the top surface of the air inlet duct 2 is fixedly connected by bolts, and the two mounting plates 8 are sealed together.

[0029] Two arc-shaped holes 4 are symmetrically opened on one side of the air inlet duct 2. Arc-shaped blocks 5 are snapped into the inside of each arc-shaped hole 4. Sealing gaskets 14 are fixedly connected to the top and bottom surfaces of the arc-shaped blocks 5. The sealing gaskets 14 slide against the inner wall of the arc-shaped holes 4. Thanks to the sealing gaskets 14 sliding against the inner wall of the arc-shaped holes 4, the inner wall of the arc-shaped holes 4 and the arc-shaped blocks 5 are sealed together, thereby preventing outside air from entering the interior of the air inlet duct 2 through the arc-shaped holes 4.

[0030] A ring 6 is fixedly connected to the inner wall of the arc-shaped block 5. An annular groove is opened on the inner wall of the air inlet duct 2, and the annular groove is connected to the arc-shaped hole 4. The ring 6 slides to extend into the interior of the annular groove. A sealing ring 15 is fixedly connected to the top and bottom surfaces of the ring 6. The outer wall of the sealing ring 15 is sealed and fitted to the inner wall of the annular groove. Thanks to the sealing ring 15 fixedly connected to the side wall of the ring 6 sliding and sealingly fitting into the interior of the annular groove opened on the inner wall of the air inlet duct 2, the air in the air inlet duct 2 can be effectively prevented from entering the interior of the factory or greenhouse through the arc-shaped groove.

[0031] The inner side of the ring 6 is fixedly connected to the dust removal net 7, which slides into the air inlet duct 2. The air entering the air inlet duct 2 from the non-powered fan 3 will be filtered by the dust removal net 7 installed on the inner wall of the ring 6, thus preventing dust in the air from entering the factory or greenhouse. The outer side of the arc-shaped block 5 is fixedly connected to the handle.

[0032] The bottom surface of the arc-shaped block 5 is provided with a mounting groove 16, and a spring 9 is fixedly connected in the mounting groove 16. A locking block 10 is fixedly connected to the end of the spring 9. The lower end of the locking block 10 slides to the bottom of the arc-shaped block 5. A locking groove 11 is provided at the lower end of the inner wall of the arc-shaped hole 4. The locking groove 11 and the locking block 10 are matched with each other. So when the arc-shaped block 5 is locked into the inside of the arc-shaped hole 4, the spring 9 pushes the locking block 10 fixedly connected to its lower end to lock into the inside of the locking groove 11, thereby effectively limiting the position of the arc-shaped block 5.

[0033] A lever 12 is fixedly connected to the locking block 10. The end of the lever 12 away from the locking block 10 slides to the outside of the arc-shaped block 5. The end of the lever 12 that slides to the outside of the arc-shaped block 5 has a longitudinal sliding stroke. So when it is necessary to release the arc-shaped block 5, the lever 12 is pulled upward. This causes the locking block 10 to move upward and out of the slot 11, thus compressing the spring 9.

[0034] A limiting groove is longitudinally formed on the inner wall of the mounting groove 16. A limiting block 13 is fixedly connected to one side of the locking block 10. The limiting block 13, which is fixedly connected to the outer wall of the locking block 10, is slidably connected to the inside of the limiting groove formed on the inner wall of the mounting groove 16. Thanks to the limiting block 13, which is fixedly connected to the outer wall of the locking block 10, being slidably connected to the inside of the limiting groove formed on the inner wall of the mounting groove 16, the sliding direction of the locking block 10 can be effectively limited.

[0035] Working principle

[0036] This dust-removing fan, when in use, first fixes the mounting plate 1 to the top of the factory or greenhouse using bolts and connects it. When the fan 3 operates, it draws air into the air inlet duct 2, which is fixedly connected to the bottom of the fan 3. Thanks to the annular groove inside the air inlet duct 2, and the sealed engagement of a ring 6 inside the groove, with a dust filter 7 fixedly connected inside the ring 6, the air entering the air inlet duct 2 through the fan 3 will be filtered by the dust filter 7 installed on the inner wall of the ring 6. This prevents dust from entering the factory or greenhouse. When too much dust accumulates on the surface of the dust filter 7, the arc-shaped block 5 is used to remove it. Pull the arc-shaped block 5 outwards towards the arc-shaped hole 4, simultaneously pulling the ring 6 and dust filter 7 out of the air inlet duct 2. This allows the dust on the top surface of the dust filter 7 to be cleaned. Since the dust filter 7 is arranged symmetrically, when cleaning the dust on the dust filter 7, first pull out the upper arc-shaped block 5 and dust filter 7. At this time, the air drawn in by the non-powered fan 3 will be filtered by the lower dust filter 7. After the dust on the upper dust filter 7 is cleaned, it is reinserted into the air inlet duct 2. Then, the lower dust filter 7 is pulled out and cleaned. This prevents dust from entering the factory or greenhouse during the cleaning of the dust on the dust filter 7.
