Description

Technical Field

[0001] This utility model relates to the field of separation device technology, specifically a high-efficiency separation device for a dust collector. Background Technology

[0002] In industrial production and environmental protection, dust collectors are key equipment for ensuring air quality and reducing dust pollution. The performance of their core separation device directly affects the dust removal effect and the stability of equipment operation. Currently, most dust collectors on the market mainly use filter screens to separate dust. Dust is carried into the device by airflow, and the filter screen filters and intercepts the dust, while clean gas is discharged from the exhaust pipe.

[0003] However, after prolonged use, dust accumulates on the filter surface, clogging the mesh and increasing airflow resistance, significantly reducing dust removal efficiency. When the filter is severely clogged, frequent replacement is required, increasing maintenance costs. Existing devices typically use a base with the filter fixed to a conical shell, making disassembly complex and cumbersome. Maintenance personnel need to spend a lot of time and effort cleaning or replacing the filter, and the additional fixed base restricts effective cleaning of the inside of the filter. Therefore, a high-efficiency separation device for dust collectors is needed to solve the problems existing in the current technology. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency separation device for a dust collector to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency separation device for a dust collector, comprising a conical shell, a dust outlet at the lower end of the conical shell, a sealing cover fixed at the upper end of the conical shell, an exhaust pipe embedded and fixed inside the sealing cover, and a vibration dust removal mechanism inside the conical shell, the vibration dust removal mechanism comprising a conical filter screen, a cross assembly frame, an assembly stud, a buffer spring, and a mesh baffle plate, the cross assembly frame being provided above the conical filter screen, the mesh baffle plate being slidably connected inside the exhaust pipe, the assembly stud being fixed at the center of the lower end face of the mesh baffle plate, and the buffer spring being sleeved on the outside of the assembly stud.

[0006] Preferably, a lifting guide block is fixed to one side surface of the mesh wind deflector, and the lifting guide block is slidably connected to the slide rail of the exhaust pipe.

[0007] Preferably, the upper end of the buffer spring is fixed to the lower end face of the mesh windbreak plate, and the cross assembly frame is slidably sleeved on the outside of the assembly stud.

[0008] Preferably, an anti-detachment knob is fixed below the cross assembly frame, and the anti-detachment knob is threadedly connected to the threaded part of the assembly stud.

[0009] Preferably, a positioning slide is fixed to the upper end face of the conical filter screen, and the cross assembly frame is fixed to the inner wall of the positioning slide.

[0010] Preferably, a positioning ring is fixed to the lower end face of the sealing cover, the positioning ring is sleeved on the outside of the positioning slide, and an air inlet pipe is fixed to one side surface of the conical shell.

[0011] This utility model provides a high-efficiency separation device for a dust collector, which has the following advantages compared with the prior art:

[0012] The vibration dust removal mechanism creates a secondary vortex that impacts the perforated baffle plate inside the exhaust pipe, causing it to slide up and down. This vibrates the conical filter screen, causing residual dust on the filter screen surface to shake off. This effectively alleviates the problem of large-area clogging of the filter screen, ensuring long-term stable operation of the filter screen and reducing the decrease in dust removal efficiency caused by clogging. The cross assembly frame, assembly studs, buffer springs, and other components work together to ensure the connection stability between the conical filter screen and the perforated baffle plate, while also providing buffering during the vibration dust removal process. This prevents damage to components due to excessive vibration, ensuring reliable operation of the device and extending its service life.

[0013] With its assembly studs, cross assembly brackets, and anti-detachment knobs, the conical filter screen can be quickly and independently removed from the sealing cover by unscrewing the anti-detachment knob and sliding out the cross assembly brackets. This facilitates subsequent replacement and thorough cleaning of the inner and outer mesh holes, reducing maintenance difficulty and costs, improving equipment maintenance efficiency, and minimizing downtime.

[0019] 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.

[0020] Please see Figure 1-4 This utility model provides a high-efficiency separation device for a dust collector, including a conical shell 1. The conical shell 1 provides a flow space for dust-laden gas, forming a spiral airflow path. Centrifugal force is used to separate dust particles from the gas. A dust outlet 3 is provided at the lower end of the conical shell 1, and a sealing cover 4 is fixed at the upper end of the conical shell 1. An exhaust pipe 13 is embedded and fixed inside the sealing cover 4. A vibration dust removal mechanism 5 is provided inside the conical shell 1. The vibration dust removal mechanism 5 includes a conical filter screen 6, a cross assembly frame 8, an assembly stud 9, a buffer spring 10, and mesh openings. A cross assembly frame 8 is provided above the wind baffle 11 and the conical filter 6. The conical filter 6 shakes off residual dust on its surface by vibrating up and down (driven by the impact of the mesh wind baffle 11) to avoid clogging of the mesh and maintain filtration efficiency. The mesh wind baffle 11 is slidably connected to the inside of the exhaust pipe 13. The assembly stud 9 is fixed at the center of the lower end face of the mesh wind baffle 11. The buffer spring 10 is sleeved on the outside of the assembly stud 9. A positioning slide 7 is fixed on the upper end face of the conical filter 6. The cross assembly frame 8 is fixed on the inner wall of the positioning slide 7.

[0021] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that a lifting guide block 12 is fixed on one side surface of the mesh baffle 11. The lifting guide block 12 is slidably connected to the slide of the exhaust pipe 13. The upper end of the buffer spring 10 is fixed at the lower end face of the mesh baffle 11. The cross assembly frame 8 is slidably sleeved on the outside of the assembly stud 9. The cross assembly frame 8 cooperates with the anti-detachment knob 15 to realize the quick assembly and disassembly of the conical filter screen 6.

[0022] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that an anti-detachment knob 15 is fixed at the bottom of the cross assembly frame 8. The anti-detachment knob 15 is threadedly connected to the threaded part of the assembly stud 9. The anti-detachment knob 15 and the assembly stud 9 cooperate to restrict the downward movement of the cross assembly frame 8 and prevent the conical filter screen 6 from falling off during vibration.

[0023] Further as Figure 1As shown, it is worth noting that a positioning ring 14 is fixed to the lower end face of the sealing cover 4. The positioning ring 14 is sleeved on the outside of the positioning slide 7, and an air inlet pipe 2 is fixed to one side surface of the conical shell 1.

[0024] The solution has the following working process: Before use, dust-laden gas enters the conical shell 1 through the spiral inlet pipe 2. The airflow spirals downward into the cone. High-density dust particles are thrown towards the cylinder wall under the action of centrifugal force and fall down along the cylinder wall to the dust outlet 3 at the bottom under the action of gravity. The rotating airflow contracts and flows towards the center in the cylinder, forming a secondary vortex upward and flowing out from the top of the equipment through the exhaust pipe 13. During this process, the conical filter 6 filters the dust-laden gas, so that the dust particles are intercepted on the outside of the conical filter 6. After the secondary vortex enters the exhaust pipe 13, it impacts the mesh baffle 11. After being impacted, the mesh baffle 11 slides upward inside the exhaust pipe 13. Under the action of airflow impact and its own gravity, the mesh baffle 11 makes the stability of the conical filter 6 poor. The conical filter 6 keeps vibrating in the up and down direction, which can facilitate the self-shaking of residual dust on its surface, thereby alleviating the situation of large-area clogging of the mesh of the conical filter 6.

[0025] When it is necessary to remove the conical filter 6, control the conical filter 6 to rotate the anti-detachment knob 15 on the cross assembly frame 8 along the assembly stud 9, and then slide it out of the cross assembly frame 8 along the assembly stud 9. This allows the conical filter 6 to be removed independently from the sealing cover 4 for subsequent replacement and thorough cleaning of the inside and outside.
