Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically a multi-stage dry filter. Background Technology

[0002] Air filtration equipment is widely used in many fields such as industrial production and indoor environmental purification, playing a crucial role in providing a clean and high-quality air environment. However, existing dry filters have some prominent problems in practical use, which seriously affect their filtration efficiency and service life.

[0003] Currently, in industrial production environments, the air often contains a large amount of large dust particles, fibers, and various fine particulate matter. Existing filters often lack effective measures to solve the problems of filter clogging and protection. This not only affects the normal operation of the filters but also requires frequent filter replacement, increasing the cost of use and maintenance workload. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a multi-stage dry filter that solves the problem of easy clogging of existing filter screens.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage dry filter, comprising a protective shell, an arc-shaped cover plate rotatably connected to the top of the protective shell, a drive motor fixedly connected to the outer side of the protective shell, and a dust-collecting fan fixedly connected to the output shaft of the drive motor; further comprising: a fan-shaped filter element movably installed on the inner side of the protective shell; a protective component fixedly connected to the side of the protective shell away from the drive motor; the protective component comprising a fixing frame, an elastic plate fixedly connected to the outer side of the fixing frame, an interception net fixedly connected to the outer side of the elastic plate, a protective soft sleeve fixedly connected to the outer side of the interception net, a metal rod fixedly connected to the outer side of the elastic plate, and a dust-collecting component rotatably connected to the center of the fixing frame; the interception net serves to initially intercept large particulate impurities.

[0008] The vacuuming component includes a collar, to the outside of which a mounting bracket is fixedly connected. An arc-shaped striking plate is rotatably connected to the outside of the mounting bracket, and the arc-shaped striking plate rotates with the mounting bracket. Under centrifugal force, the arc-shaped striking plate contacts a metal rod.

[0009] Preferably, the vacuum fan is located inside the protective shell, and the output shaft of the drive motor is fixedly connected to the center of the protective assembly. When the fan-shaped filter needs to be replaced, it can be taken out from the protective shell simply by opening the arc-shaped cover.

[0010] Preferably, the outer side of the fixing frame is fixedly connected to the side of the protective shell away from the drive motor, and the side of the protective soft sleeve away from the interception net is fixedly connected to the outer side of the fixing frame. The protective soft sleeve can protect the interception net and seal the interception net and the fixing frame at the same time.

[0011] Preferably, the center of the fixed frame is rotatably connected to the output shaft of the drive motor, and the outer side of the collar is rotatably connected to the center of the fixed frame. The collar rotates together with the output shaft of the drive motor, thereby driving the mounting frame and the guide plate to rotate.

[0012] Preferably, the inner side of the collar is fixedly connected to the output shaft of the drive motor, and the inner side of the mounting bracket is fixedly connected to a guide plate. During rotation, the guide plate can guide air to pass more smoothly through the protective components into the interior of the protective shell, and can also accelerate the air to a certain extent, thereby increasing the airflow speed.

[0013] Preferably, a limiting plate is fixedly connected to the outer side of the arc-shaped striking plate, and the outer side of the arc-shaped striking plate is in contact with the outer side of the metal rod. When the arc-shaped striking plate strikes the metal rod, the elastic plate vibrates, and the vibration of the elastic plate can cause the interception net to shake, shaking off large particles of impurities intercepted on the interception net.

[0014] (III) Beneficial Effects

[0015] This utility model provides a multi-stage dry filter. It has the following beneficial effects:

[0016] (I) The filter performs multi-stage filtration of air by setting up protective components and fan-shaped filter elements. In the protective components, the interception net plays a role in initially intercepting large particulate impurities. The protective soft sleeve on the outside of the interception net can protect the interception net. When the interception net is impacted by impurities, the elastic plate can generate a certain elastic deformation to avoid damage to the interception net due to rigid collision. At the same time, it seals the interception net and the fixed frame.

[0017] (II) This filter incorporates a dust-collecting component. The collar rotates along with the output shaft of the drive motor, which in turn drives the mounting bracket and the guide plate to rotate. During rotation, the guide plate guides air more smoothly through the protective components into the protective housing and also accelerates the airflow, increasing its speed.

[0018] (III) This filter incorporates a dust-collecting component. During the rotation of the mounting frame, the arc-shaped striking plate rotates along with the frame. When the arc-shaped striking plate contacts the metal rod under centrifugal force, it strikes the metal rod, causing the elastic plate to vibrate. This vibration of the elastic plate shakes the interception net, dislodging large particles of impurities trapped on it, preventing blockage, and ensuring smooth airflow. Attached Figure Description

Detailed Implementation

[0024] 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.

[0025] Example: Please refer to Figure 1-4This utility model provides a technical solution: a multi-stage dry filter, including a protective shell 1, an arc-shaped cover plate 2 rotatably connected to the top of the protective shell 1, a drive motor 3 fixedly connected to the outside of the protective shell 1, and a vacuum fan 4 fixedly connected to the output shaft of the drive motor 3. It also includes: a fan-shaped filter element 5 movably installed inside the protective shell 1, and a protective component 6 fixedly connected to the side of the protective shell 1 away from the drive motor 3. When the drive motor 3 is started, its output shaft drives the vacuum fan 4 to rotate. The rotation of the vacuum fan 4 generates suction, allowing external air to enter the protective shell 1 from the side where the protective component 6 is installed. After the air is initially filtered by the protective component 6, the fan-shaped filter element 5 further filters the remaining impurities in the air, purifying the air and completing the multi-stage air filtration process. When the fan-shaped filter element 5 needs to be replaced, it can be removed from the protective shell 1 simply by opening the arc-shaped cover plate 2 for easy replacement.

[0026] The protective component 6 includes a fixed frame 61, an elastic plate 62 fixedly connected to the outside of the fixed frame 61, an interception net 63 fixedly connected to the outside of the elastic plate 62, a protective soft sleeve 64 fixedly connected to the outside of the interception net 63, and a metal rod 65 fixedly connected to the outside of the elastic plate 62. A dust collection component 66 is rotatably connected to the center of the fixed frame 61. The dust collection fan 4 is located inside the protective shell 1. The output shaft of the drive motor 3 is fixedly connected to the center of the protective component 6. The outside of the fixed frame 61 is fixedly connected to the side of the protective shell 1 away from the drive motor 3. The side of the protective soft sleeve 64 away from the interception net 63 is fixedly connected to the outside of the fixed frame 61. The interception net 63 plays a role in initially intercepting large particles of impurities. The protective soft sleeve 64 on the outside of the interception net 63 can protect the interception net 63. When the interception net 63 is impacted by impurities, the elastic plate 62 can generate a certain elastic deformation to prevent the interception net 63 from being damaged by rigid collision. At the same time, it seals the interception net 63 and the fixed frame 61.

[0027] The vacuuming component 66 includes a collar 601. A mounting bracket 602 is fixedly connected to the outer side of the collar 601. An arc-shaped striking plate 604 is rotatably connected to the outer side of the mounting bracket 602. The center of the mounting bracket 61 is rotatably connected to the output shaft of the drive motor 3. The outer side of the collar 601 is rotatably connected to the center of the mounting bracket 61. The inner side of the collar 601 is fixedly connected to the output shaft of the drive motor 3. A guide plate 603 is fixedly connected to the inner side of the mounting bracket 602. A limit plate 605 is fixedly connected to the outer side of the arc-shaped striking plate 604. The outer side of the arc-shaped striking plate 604 contacts the outer side of the metal rod 65. The collar 601 rotates together with the output shaft of the drive motor 3, thereby driving the mounting bracket 602 and the guide plate 603 to rotate. During rotation, the deflector 603 guides air more smoothly through the protective component 6 into the protective shell 1 and accelerates the airflow, increasing its speed. As the mounting bracket 602 rotates, the arc-shaped striking plate 604 rotates with it. When the arc-shaped striking plate 604 contacts the metal rod 65 under centrifugal force, it strikes the metal rod 65, causing the elastic plate 62 to vibrate. This vibration shakes the intercepting net 63, dislodging large particles and preventing blockage, thus ensuring smooth airflow. The limiting plate 605 restricts the maximum deflection distance of the arc-shaped striking plate 604.

[0028] When in use, the drive motor 3 starts, and its output shaft drives the vacuum fan 4 to rotate. The rotation of the vacuum fan 4 generates suction, which allows outside air to enter the protective shell 1 from the side where the protective component 6 is installed. After the air is initially filtered by the protective component 6, it enters the protective shell 1. The fan-shaped filter element 5 further filters the remaining impurities in the air, purifying the air and completing the multi-stage air filtration process. When it is necessary to replace the fan-shaped filter element 5, simply open the arc-shaped cover plate 2 to remove it from the protective shell 1 for easy replacement.

[0029] In the protective component 6, the interception net 63 plays a role in initially intercepting large particles of impurities. The protective soft sleeve 64 on the outside of the interception net 63 can protect the interception net 63. When the interception net 63 is impacted by impurities, the elastic plate 62 can produce a certain elastic deformation to prevent the interception net 63 from being damaged by rigid collision. At the same time, it seals the interception net 63 and the fixing frame 61.

[0030] During this process, the output shaft of the drive motor 3 drives the dust collection component 66 to rotate synchronously, and the collar 601 rotates together with the output shaft of the drive motor 3, thereby driving the mounting bracket 602 and the guide plate 603 to rotate. During the rotation, the guide plate 603 can guide the air to enter the protective shell 1 more smoothly through the protective component 6, and can also accelerate the air to a certain extent, increasing the airflow speed.

[0031] During the rotation of the mounting frame 602, the arc-shaped striking plate 604 rotates together with the mounting frame 602. When the arc-shaped striking plate 604 contacts the metal rod 65 under the action of centrifugal force, the arc-shaped striking plate 604 strikes the metal rod 65, thereby causing the elastic plate 62 to vibrate. The vibration of the elastic plate 62 can cause the interception net 63 to shake, shaking off large particles of impurities intercepted on the interception net 63, preventing impurities from clogging the interception net 63, and ensuring that air can pass through smoothly. Among them, the limiting plate 605 limits the maximum deflection distance of the arc-shaped striking plate 604.
