Description

TECHNICAL FIELD

[0001] The present application relates to the field of separation equipment technology, in particular to a cyclone separator. BACKGROUND

[0002] The cyclone separator is a device for separating gas-solid or liquid-solid systems. The working principle is that the rotational motion is caused by the tangential introduction of gas flow. The solid particles with higher density are thrown to the wall under the action of centrifugal force and fall along the cylinder wall under the action of gravity, and finally discharged through the dust collecting hopper at the bottom. The clean gas is discharged through the exhaust pipe.

[0003] When graphite needs to be separated during processing, a cyclone separator is often used for operation. Excessive gas flow may cause graphite dust particles to not fully settle in the cyclone separator, and too fast flow rate may cause particles to be carried away by the gas flow, reducing the separation efficiency. Due to too many or too large solid particles carried away by the upward gas flow, the exhaust pipe inside the cyclone separator may be blocked, resulting in a decrease in separation efficiency. CONTENT OF THE INVENTION

[0004] In order to prevent the exhaust pipe from being blocked and improve the separation effect of the cyclone separator, the present application provides a cyclone separator.

[0005] The cyclone separator provided by the present application adopts the following technical scheme:

[0006] A cyclone separator, comprising a separator body, the separator body comprising a feed pipe, an exhaust pipe, a cyclone body and a dust collecting hopper fixed to the lower end of the cyclone body, the cyclone body being vertically tapered, the feed pipe being connected to the upper side of the cyclone body, and the exhaust pipe being provided in the upper end of the cyclone body and extending inside the cyclone body; a cleaning filter plate is inserted at a position away from the cyclone body inside the exhaust pipe, the cleaning filter plate covering the radial cross section of the exhaust pipe, the cleaning filter plate being upwardly provided in the exhaust pipe and being capable of sliding in the direction of insertion; the cleaning filter plate comprises a fiber plate and a bottom plate arranged on the same axis, the fiber plate being arranged close to the cyclone body, and a plurality of through holes being provided in the fiber plate and the bottom plate in one-to-one correspondence; a dust collecting box is fixed to the position of the exhaust pipe corresponding to the cleaning filter plate, the dust collecting box being connected to the inside of the exhaust pipe, the dust collecting box being capable of collecting dust intercepted by the cleaning filter plate, thereby achieving effective separation and collection of dust-containing gas, improving dust treatment efficiency, preventing the exhaust pipe from being blocked and improving the separation effect of the cyclone separator.

[0007] By adopting the technical scheme, the gas separated by the cyclone body enters the exhaust pipe, and the cleaning filter plate is installed in the exhaust pipe. When the airflow passes through the cleaning filter plate, it first passes through the fiber plate for preliminary filtration to intercept most of the dust particles, and then passes through the bottom plate for secondary filtration. The gas filtered by the cleaning filter plate continues to rise and is discharged from the cyclone separator. The intercepted dust particles fall into the dust collection box below the cleaning filter plate.

[0008] Optionally, the fiber plate is made of cotton fiber plate or hemp fiber plate.

[0009] By adopting the technical scheme, cotton or hemp is a material with a porous structure. The use of cotton fiber plate or hemp fiber plate can increase the surface area in contact with the airflow, thereby providing more dust adsorption sites and improving the adsorption effect.

[0010] Optionally, the cleaning filter plate is provided with a water tank at the upper end of the exhaust pipe position. The water tank is provided with a moisture guide pipe that extends and abuts against the fiber plate to keep the fiber plate moist.

[0011] By adopting the technical scheme, the moisture guide pipe can guide the water in the water tank to the fiber plate, keeping the fiber plate wet and moist. The moisture can increase the adhesion of the fiber plate surface, making it easier to adsorb graphite particles and improving the adsorption effect.

[0012] Optionally, the size of the through hole on the fiber plate is smaller than the size of the through hole on the bottom plate.

[0013] By adopting the technical scheme, the dust is effectively intercepted by the fiber plate, reducing the dust load on the bottom plate and prolonging the service life of the bottom plate. In addition, the smaller size of the through hole means that the fiber plate has a higher surface area, which can better adsorb and intercept dust and enhance its filtering effect.

[0014] Optionally, two scrapers are provided in the exhaust pipe corresponding to the position where the cleaning filter plate is arranged. The two scrapers are arranged at the two ends of the cleaning filter plate along the axial direction.

[0015] By adopting the technical scheme, scrapers are arranged on both sides of the cleaning filter plate. When the cleaning filter plate is removed from the exhaust pipe, the scrapers can abut against the cleaning filter plate and clean evenly along the entire length of the cleaning filter plate, effectively preventing dust from accumulating in a certain part of the cleaning filter plate and improving the adsorption effect of the cleaning filter plate.

[0016] Optionally, a partition plate is arranged in the dust collection box, and the partition plate is in the same vertical plane as the cleaning filter plate.

[0017] By adopting the technical scheme, the setting of the partition plate can avoid the airflow directly passing through the dust collecting box. Meanwhile, the partition plate divides the internal space of the dust collecting box into different areas, so that the dust intercepted by the cleaning filter plate can be more evenly distributed in the dust collecting box. This helps to prevent the dust from excessively accumulating in a local area of the dust collecting box, thereby improving the utilization efficiency and collection effect of the dust collecting box.

[0018] Optionally, a convex rib is fixed at a position close to the lower end of the outer side of the dust collecting box, and two semicircular clamping rings adapted to the convex rib are hinged at positions corresponding to the convex rib of the dust collecting box.

[0019] By adopting the technical scheme, the convex rib and the semicircular clamping ring can clamp the dust collecting bag, facilitating the replacement of the dust collecting bag by the staff.

[0020] Optionally, a dustproof baffle is arranged at the connection position between the cyclone body and the dust collecting hopper, the dustproof baffle comprises an inclined section and a vertical section connected in sequence from top to bottom, the inclined section is arranged in a conical shape, the diameter of the upper end of the inclined section is greater than that of the lower end, and the vertical section is arranged in a vertical state.

[0021] By adopting the technical scheme, the inclined section is designed in a conical shape, and the diameter of the upper end is greater than that of the lower end. This shape makes the dust more easily guided and flow downward along the inner wall of the inclined section under the action of the airflow in the cyclone body, and then quickly falls into the dust collecting hopper through the vertical section, thereby effectively preventing the dust from escaping back to the cyclone body from the connection between the cyclone body and the dust collecting hopper.

[0022] In summary, the present application has at least one of the following beneficial technical effects:

[0023] 1. In the exhaust pipe, a cleaning filter plate is installed. When the airflow passes through the cleaning filter plate, it first passes through the fiber plate for preliminary filtration, intercepting most of the dust particles, and then passes through the bottom plate for secondary filtration. The gas filtered by the cleaning filter plate continues to rise and is discharged from the cyclone separator. The intercepted dust particles fall into the dust collecting box below the cleaning filter plate, achieving effective separation and collection of dust-containing gas, improving dust handling efficiency, preventing the exhaust pipe from being blocked, and improving the separation effect of the cyclone separator.

[0024] 2. Both cotton and hemp are materials with porous structure. The use of cotton fiber plate or hemp fiber plate can increase the surface area in contact with the airflow, thereby providing more dust adsorption sites and improving the adsorption effect.

[0025] 3. The design of the inclined section adopts a conical structure, the diameter of the upper end is larger than that of the lower end, which makes the dust more easily guided and flow downward along the inner wall of the inclined section under the action of the airflow in the cyclone body, and then quickly falls into the dust hopper through the vertical section, thereby effectively preventing the dust from escaping back to the cyclone body from the connection between the cyclone body and the dust hopper.

DETAILED DESCRIPTION

[0031] The following will be described in detail in combination with the accompanying drawings. Figures 1-4 The present application will be further described in detail.

[0032] The present application discloses a cyclone separator. Referring to Figure 1A cyclone separator comprises a feed pipe 1, an exhaust pipe 4, a cyclone body 2 and a dust hopper 3. The cyclone body 2 is vertically arranged in a conical shape, and a support 21 is fixed to the outer side of the cyclone body 2 to support the cyclone body 2. The feed pipe 1 is fixed to the upper side of the cyclone body 2 and is in communication with the cyclone body 2, and the gas containing dust particles enters the cyclone body 2 through the feed pipe 1 for separation. The exhaust pipe 4 is fixed to the upper end of the cyclone body 2 and extends vertically downward into the interior of the cyclone body 2, and the gas separated in the cyclone body 2 forms an upward internal vortex flow into the exhaust pipe 4 and out of the cyclone body 2. The dust hopper 3 is fixed to the lower end of the cyclone body 2 and is coaxially arranged with the cyclone body 2, and the separated dust particles enter the dust hopper 3 for temporary storage. The dust hopper 3 is conical in shape and gradually decreases in size from top to bottom. The upper end of the dust hopper 3 is directly larger in diameter than the lower end of the cyclone body 2, increasing the collection area, and the dust hopper 3 can more effectively collect the dust particles falling from the cyclone body 2, reducing the accumulation of dust in the interior of the cyclone body 2. A larger dust hopper 3 design helps to improve airflow distribution, making it easier for dust particles to be collected, thereby improving overall collection efficiency. A rotary air lock 32 is rotatably connected to the lower end of the interior of the dust hopper 3, and the rotating blades of the rotary air lock 32 uniformly and continuously discharge the separated dust from the dust hopper 3, while preventing backflow of gas or dust, ensuring continuity and stability during discharging.

[0033] Reference Figure 2 A dust baffle 31 is fixed to the position where the dust hopper 3 is connected to the cyclone body 2, and the dust baffle extends downward into the dust hopper 3. The dust baffle comprises an inclined section 311 and a vertical section 312 connected in sequence from top to bottom, the inclined section 311 is arranged in an inverted conical shape, and the upper end of the inclined section 311 is larger in diameter than the lower end. The vertical section 312 is cylindrical in shape, and the diameter of the vertical section 312 is the same as the diameter of the lower end of the inclined section 311. During separation, the separated dust slides from the inner wall of the cyclone body 2 onto the dust baffle 31, slides along the inclined section 311 of the dust baffle 31, and then quickly slides through the vertical section 312 of the dust baffle 31, and the cross-sectional size of the vertical section 312 is much smaller than the diameter of the lower end of the cyclone body 2, effectively reducing the re-entry of dust and other solid particles from the dust hopper 3 into the cyclone body 2, reducing the overflow of dust under the action of the upward rotating airflow, and the dust baffle 31 has a simple structure and good dust prevention effect.

[0034] Reference Figure 2 and 3The exhaust pipe 4 is provided with a cleaning filter plate 5, the cleaning filter plate 5 is arranged along the radial direction of the exhaust pipe 4, the cleaning two side plates completely cover the radial cross section of the exhaust pipe 4, and the cleaning filter plate 5 is vertically arranged in the exhaust pipe 4. A sliding groove is formed in the inner wall of the exhaust pipe 4 corresponding to the position of the cleaning filter plate 5. The cleaning filter plate 5 can slide up and down along the sliding groove, and the cleaning filter plate 5 can be completely taken out from the exhaust pipe 4 along the sliding groove, which is convenient for regular removal and thorough cleaning of the cleaning two side plates. The cleaning filter plate 5 includes a fiber plate 51 and a bottom plate 52 which are arranged in the same shape and overlap each other, and the fiber plate 51 is arranged close to the cyclone body 2 compared with the bottom plate 52. The fiber plate 51 is made of cotton or hemp fiber plate 51, and the cotton or hemp material is a porous structure, which can provide more adsorption area, and has good adsorption and filtering performance, and can efficiently intercept dust. The design of the bottom plate 52 enhances the stability of the overall structure of the cleaning filter plate 5.

[0035] Reference Figure 2 and 3 A plurality of through holes 53 are formed on the fiber plate 51 and the bottom plate 52, and the through holes 53 on the fiber plate 51 correspond to the through holes 53 on the bottom plate 52 one by one. The diameter of the through hole 53 on the fiber plate 51 is smaller than the diameter of the through hole 53 on the bottom plate 52. When the airflow passes through the cleaning filter plate 5, it first passes through the primary adsorption of the surface porous fiber plate 51 and then passes through the bottom plate 52 to complete the filtration. The diameter of the through hole 53 on the fiber plate 51 is smaller than the diameter of the through hole 53 on the bottom plate 52, so the fiber plate 51 can effectively filter and adsorb dust in the airflow, reducing the probability of dust blocking the through hole 53 on the bottom plate 52.

[0036] Reference Figure 2 and 3 A water tank 54 is fixedly connected to the outer wall of the exhaust pipe at the position corresponding to the cleaning filter plate 5, and the water tank 54 is vertically arranged upwards. The inside of the water tank 54 is in a constant pressure state, and the inside of the water tank 54 is used for storing water. A moisture guide pipe 541 is fixedly connected in the water tank 54, and the moisture guide pipe 541 is arranged in the side wall of the water tank 54 close to the exhaust pipe. The moisture guide pipe 541 extends downward and abuts against the upper end of the fiber plate 51. The moisture guide pipe 541 guides the water in the water tank 54 into the fiber plate 51 through capillary action, so that the fiber plate 51 is kept in a wet state. The wet fiber plate 51 can more effectively adsorb dust, improving the filtering effect of the cleaning filter plate 5.

[0037] Referring to Figures 2 and 3, a dust box 6 is fixedly connected to the lower side of the exhaust pipe at the position corresponding to the clean filter plate 5. The upper end of the dust box 6 is connected to the exhaust pipe in the vertical direction, and the lower end of the dust box 6 is connected to the outside world in the vertical direction. The dust box 6 is located directly below the clean filter plate 5. The dust box 6 can effectively collect the dust intercepted by the clean filter plate 5, thereby improving the dust collection efficiency. At the same time, a partition plate 61 is fixedly connected to the inside of the dust box 6 in the vertical direction. The partition plate 61 and the clean filter plate 5 are in the same vertical plane. The partition plate abuts against the lower side of the clean filter plate 5, supporting the clean filter plate 5 while separating the space on both sides of the clean side plates along the axial direction, ensuring that the airflow in the exhaust pipe 4 is filtered through the clean filter plate 5, avoiding secondary contamination of dust. A ridge 62 is fixedly provided on the outer wall of the dust box 6 near the lower end. Two semicircular snap rings 63 are hingedly connected to one end of the dust box 6 at the position corresponding to the ridge 62. The two semicircular snap rings 63 can be locked together away from the hinge position. The inner walls of the two semicircular snap rings 63 are provided with grooves corresponding to the size of the ridges 62, and the two semicircular snap rings 63 wrap around the ridges 62. During use, a dust bag 65 is sleeved on the lower side of the outer wall of the dust box 6, and the inner wall of the dust bag 65 abuts the outer side of the ridges 62. The two semicircular snap rings 63 are then matched and fixed, and the dust bag 65 is fixed to the dust box 6 to collect the dust in the dust box 6, making it convenient for staff to collect and replace the dust. Two plug-ins 64 are inserted horizontally into the dust box 6. Both plug-ins 64 are arranged perpendicular to the partition 61. The two plug-ins 64 cooperate to fully cover the horizontal cross-section of the dust box 6. The two plug-ins 64 can slide away from the partition 61 and detach from the dust box 6. When the plug-ins 64 are inserted into the dust box 6, the dust box 6 is disconnected from the dust bag 65. When the dust in the mobile phone dust collection box 6 is needed, the inserting plates 64 are pulled out in the direction away from the partition plate 61 and the dust is discharged respectively, which is convenient for the operator to operate and avoids secondary pollution of the dust.

[0038] refer to Figure 3 and 4 Two scrapers 41 are fixedly attached to the inner wall of the exhaust duct along the axial direction. The two scrapers 41 are located on either side of the clean filter plate 5. The ends of the two scrapers 41 facing away from the exhaust duct abut against the ends of the fiberboard 51 and the bottom plate 52 facing away from each other. When the clean filter plate 5 is removed, the scrapers 41 scrape off the dust accumulated on the clean filter plate 5 and drop it into the dust collection box at the bottom of the clean filter plate 5, completing the cleaning process and ensuring the clean filter plate 5 continues to perform its effective filtering function.

[0039] The cyclone separator of the present embodiment operates as follows: Gas containing dust particles enters cyclone 2 through feed pipe 1. Due to the conical design of cyclone 2, the gas forms a rotating airflow within cyclone 2. During this process, heavier dust particles are flung toward the inner wall of cyclone 2 due to centrifugal force and slide down along the inner wall into dust hopper 3. Meanwhile, the gas, having undergone preliminary separation, continues to rise and enters exhaust pipe 4.

[0040] In the exhaust pipe 4, a cleaning filter plate 5 is installed, and the airflow passes through the fiber plate 51 for preliminary filtration, intercepting most of the dust particles, and then passes through the bottom plate 52 for secondary filtration. The fiber plate 51 has a porous structure, good adsorption and filtration performance, and can effectively adsorb dust in the airflow. At the same time, the wet fiber plate 51 can further improve its adsorption effect due to the action of the moisture guide pipe 541.

[0041] The gas filtered by the cleaning filter plate 5 continues to rise and is discharged from the cyclone separator. The intercepted dust particles fall into the dust collection box 6 below the cleaning filter plate 5, realizing effective separation and collection of dust-containing gas, improving dust treatment efficiency, preventing the exhaust pipe 4 from being blocked, and improving the separation effect of the cyclone separator. The partition plate 61 in the dust collection box 6 divides the space into two parts, ensuring that the airflow must pass through the cleaning filter plate 5 for filtration, avoiding secondary pollution of dust. The design of the dust collection box 6 also facilitates dust collection and cleaning, and through the setting of the plug-in plate 64 and the snap ring, the dust collection box 6 can be easily taken out and the dust collection bag 65 can be replaced.

[0042] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, therefore: any equivalent changes made according to the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
