Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dust removal, in particular to a high-efficiency dust removal device. Background Art
[0002] In the silk-making workshop, the cyclone dust collector is mainly used to remove dust from the airflow. The traditional cyclone dust collector mainly includes a cylinder, a cone, an air intake pipe, an exhaust pipe and a dust discharge pipe. The working principle is that the airflow containing dust enters the cylinder from the air intake pipe and forms a vortex in the cone. Under the action of centrifugal force, the dust is forced to leave the airflow, slide down along the cone wall, and finally gather in the dust discharge pipe at the bottom of the cone, while the airflow is discharged through the exhaust pipe.
[0003] However, when there is too much dust, part of the dust in the existing cyclone dust collector will move with the airflow, causing secondary dust and affecting the dust removal effect. Utility Model Content

[0007] Furthermore, the elastic limit assembly includes two first elastic limit members, which are respectively arranged on both sides of the mounting groove. When the end of the sealing plate is against the first elastic limit member, the first elastic limit member provides a first rotational resistance for the rotating shaft. When the filter screen located in the cone is blocked, the thrust applied by the airflow to the filter screen is greater than the first rotational resistance, so that the sealing plate can overcome the first rotational resistance applied by the first elastic limit member to the filter screen and rotate until the end of the sealing plate is against the first elastic limit member again, and the filter screen located in the mounting cavity rotates into the cone.
[0008] Furthermore, the dust interception mechanism also includes a dust cleaning component, which is used to clean the filter located in the installation cavity. A dust removal channel is provided at the bottom of the installation cavity, and the bottom of the dust removal channel is connected to the dust removal hopper.
[0009] Furthermore, the dust cleaning assembly includes a plurality of second elastic limiters, which are arranged on the inner wall of the installation cavity. The second elastic limiters provide a second rotational resistance for the blocking plate. The blocking plate hits the second elastic limiters one by one to cause the filter to vibrate.
[0010] Furthermore, a slot is provided on the rotating shaft, a mounting bar is provided on the filter screen, the mounting bar is rotatably installed in the slot, and a vibration gap is provided in the slot in the rotation direction of the sealing plate, and the vibration gap is used to increase the vibration amplitude of the filter screen.
[0011] Furthermore, a plurality of shells are arranged outside the cone, and mounting grooves are opened on the cone.

[0014] Furthermore, a sealing strip is provided at the end of the sealing plate.
[0015] Beneficial effects of the utility model:
[0016] 1. The dust in the airflow is intercepted by setting the filter to avoid secondary dust. And through the blocking plate and the elastic limit assembly, when the filter in the cone is blocked, the thrust exerted by the airflow on the filter is greater than the first rotation resistance, the shaft rotates, and the blocking plate can forcefully pass through the elastic limit assembly until the filter in the installation cavity rotates into the cone to continue filtering the dust in the airflow.
[0017] 2. By providing the first elastic limiting member, both the elastic limiting function can be achieved and the sealing effect of the sealing plate can be improved.

[0033] like Figure 1-Figure 5 As shown, a high-efficiency dust removal device of the utility model includes a cylinder 11, a cone 12, an air inlet pipe 13, an exhaust pipe 14 and a dust hopper 15. A plurality of installation cavities 121 are arranged on the cone 12. Specifically, a plurality of shells 2 are arranged outside the cone 12. A mounting groove 122 is opened on the cone 12. The shells 2 correspond to the mounting grooves 122 one by one. Both sides of the shell 2 are sealed and connected to the outer surface of the cone 12. In this embodiment, both sides of the shell 2 are integrally formed with the outer surface of the cone 12. According to actual conditions, welding and other methods can also be used to achieve a sealed connection between the two sides of the shell 2 and the outer surface of the cone 12. The installation cavity 121 is formed by the area between the shell 2 and the mounting groove 122. The bottom of the shell 2 is connected to the dust hopper 15 to form a dust removal channel 21.
[0034] In this embodiment, six installation cavities 121 are provided, and each installation cavity 121 is provided with a dust interception mechanism, which includes a dust interception component, an elastic limit component and a dust cleaning component. Specifically:
[0035] The dust interception assembly is rotatably installed in the installation cavity 121. The dust interception assembly includes a rotating shaft 31 and two filter screens 32 and two blocking plates 33 connected to the rotating shaft 31. One of the two filter screens 32 is located in the cone 12, and the other is located in the installation cavity 121. The filter screen 32 is used to filter dust in the airflow to prevent dust from following the airflow and causing secondary dust. The blocking plate 33 is used to block the installation slot 122 to prevent the airflow from entering the installation slot 122. Specifically, the filter screen 32 and the blocking plate 33 are arranged at equal angles along the circumference of the rotating shaft 31, and the filter screen 32 and the blocking plate 33 are arranged at intervals. The upper and lower ends of the rotating shaft 31 are rotatably connected to the upper and lower ends of the installation cavity 121. Specifically, the upper and lower ends of the installation slot 122 are provided with shaft holes, and the rotating shaft 31 is rotatably inserted into the shaft hole. When the rotating shaft 31 rotates, the filter screen 32 and the blocking plate 33 can be driven to rotate at the same time. The blocking plate 33 abuts against the elastic limiting assembly to block the installation slot 122. The elastic limiting assembly is used to switch the position of the filter screen 32 in the installation cavity 121 and the filter screen 32 in the cone 12.
[0036] The elastic limit assembly can abut against the blocking plate 33 to provide a first rotational resistance for the rotating shaft 31 and block the rotation of the rotating shaft 31. When the filter 32 located in the cone 12 is blocked, the thrust exerted by the airflow on the filter 32 is greater than the first rotational resistance, and the rotating shaft 31 rotates, so that the blocking plate 33 can forcefully pass through the elastic limit assembly until the filter 32 located in the installation cavity 121 rotates into the cone 12, and continues to filter the dust in the airflow to prevent the dust from following the airflow and causing secondary dust. At this time, since the filter 32 located in the cone 12 is not blocked, the thrust exerted by the airflow on the filter 32 is less than the first rotational resistance, and the elastic limit assembly can block the rotation of the rotating shaft 31. Specifically, the elastic limit assembly includes two first elastic limit members 4, and the two first elastic limit members 4 are respectively arranged on both sides of the installation groove 122. When the end of the sealing plate 33 is against the first elastic limit member 4, the first elastic limit member 4 provides a first rotation resistance for the rotating shaft 31. When the filter screen 32 located in the cone 12 is blocked, the thrust applied by the airflow to the filter screen 32 is greater than the first rotation resistance, and the rotating shaft 31 rotates, so that the sealing plate 33 can be forced to pass through the first elastic limit member 4 until the filter screen 32 located in the installation cavity 121 rotates into the cone 12.
[0037] It should be noted that the width of the blocking plate 33 is greater than the width of the filter screen 32 to prevent the filter screen 32 from being blocked by the elastic limiting component when rotating, causing the dust on the filter screen 32 to fall off due to the vibration of the filter screen 32. In this embodiment, a sealing strip 331 is provided at the end of the blocking plate 33, and when the blocking plate 33 abuts against the first elastic limiting member 4, the sealing between the blocking plate 33 and the first elastic limiting member 4 can be improved.
[0038] The dust cleaning assembly is used to clean the filter 32 located in the installation cavity 121, and the dust cleaned by the dust cleaning assembly is collected in the dust hopper 15 through the dust discharge channel 21. Specifically, the dust cleaning assembly includes a plurality of second elastic stoppers 5, and the plurality of second elastic stoppers 5 are arranged on the inner wall of the installation cavity 121. The second elastic stoppers 5 provide a second rotation resistance for the blocking plate 33, and the second rotation resistance is less than the first rotation resistance. The blocking plate 33 hits the second elastic stoppers 5 one by one to make the filter 32 vibrate. When the blocking plate 33 rotates, the second elastic stoppers 5 will provide a second rotation resistance to the blocking plate 33, and the second rotation resistance is less than the thrust applied by the airflow to the dust interception assembly. Therefore, the blocking plate 33 will hit the second elastic stoppers 5 one by one to make the filter 32 vibrate. When the filter 32 vibrates, the dust on the filter 32 falls into the dust discharge channel 21, and the dust on the filter 32 is automatically cleaned so that the filter 32 can be recycled. It should be noted that, in this embodiment, a plurality of second elastic limit members 5 are arranged in the rear half of the installation cavity 121. Only after the filter screen 32 located in the cone 12 enters the installation cavity 121 will the sealing plate 33 hit the second elastic limit member 5 so that the dust detached from the filter screen 32 can smoothly enter the dust removal channel 21.
[0039] In this embodiment, the blocking plate 33 is integrally formed with the rotating shaft 31, and the filter 32 is rotatably mounted on the rotating shaft 31. Specifically, a notch 311 is provided on the rotating shaft 31, and a mounting bar 321 is provided on the filter 32. The mounting bar 321 is rotatably mounted in the notch 311, and a vibration gap 312 is provided in the notch 311 in the rotation direction of the blocking plate 33. The vibration gap 312 is used to increase the vibration amplitude of the filter 32. When the blocking plate 33 hits the second elastic stopper 5, due to the existence of the vibration gap 312, the filter 32 will continue to rotate a certain amplitude under the action of inertia until one side of the mounting bar 321 hits the side wall of the vibration gap 312, and after the blocking plate 33 passes through the second elastic stopper 5, the side wall of the notch 311 will hit the other side of the mounting bar 321, which effectively increases the vibration amplitude of the filter 32 and improves the cleaning effect of the dust on the filter 32.
[0040] The working principle of the utility model is as follows:
[0041] The airflow in the cone 12 blows through the filter 32, and the filter 32 intercepts the dust in the airflow. When the filter 32 located in the cone 12 is blocked, the thrust applied by the airflow to the filter 32 is greater than the first rotational resistance, the rotating shaft 31 rotates, and the sealing plate 33 is forced through the elastic limiting assembly until the filter 32 located in the installation cavity 121 rotates into the cone 12 to continue filtering the dust in the airflow.
[0042] During this process, the second elastic stopper 5 provides a second rotational resistance to the blocking plate 33, and the second rotational resistance is less than the thrust exerted by the airflow on the dust interception assembly. The blocking plates 33 will hit the second elastic stopper 5 one by one, causing the filter 32 to vibrate. When the filter 32 vibrates, the dust on the filter 32 falls into the dust discharge channel 21 and is collected in the dust discharge hopper 15. When the blocking plate 33 hits the second elastic stopper 5, due to the existence of the vibration gap 312, the filter 32 will continue to rotate a certain amplitude under the action of inertia until one side of the mounting bar 321 hits the side wall of the vibration gap 312. After the blocking plate 33 passes through the second elastic stopper 5, the side wall of the notch 311 will hit the other side of the mounting bar 321, effectively increasing the vibration amplitude of the filter 32 and improving the cleaning effect of the dust on the filter 32.

Although the utility model is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
