Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of powder feeding equipment, and in particular relates to a vacuum feeding machine with a cyclone separation function. Background Art
[0002] A vacuum loader is a device that uses the principle of vacuum negative pressure to suck powder, granular or small block materials and transports the materials to a designated location through a pipe. It is usually used in industries that require pneumatic conveying, such as food, medicine, and chemicals, to achieve pneumatic conveying of materials.
[0003] Existing vacuum loaders generally include a barrel, which is provided with a feed pipe and a negative pressure device. The negative pressure device is connected to the barrel. The negative pressure device can use a negative pressure fan, a vacuum pump, a vacuum generator, etc. The negative pressure device can vacuum the feed pipe and the inside of the barrel. After the material enters through the feed pipe, the vacuum loader sucks the material into the barrel under a negative pressure environment. A filter element is provided in the barrel, which can filter impurities to reduce damage to other components of the vacuum loader.
[0004] However, when the negative pressure equipment sucks materials through negative pressure, the heavier materials fall into the barrel under the action of gravity, while the lighter materials float upward due to the suction of the negative pressure equipment and adhere to the surface of the filter element, which can easily cause the filter element to be blocked. Utility Model Content
[0005] In order to solve the shortcomings of the existing technology, the utility model provides a vacuum loader with a cyclone separation function. The separation structure prevents the material from entering the dust removal chamber directly with the gas. The material needs to be settled through the cyclone tube after entering the cyclone chamber, and then enter the dust removal chamber through the cyclone tube. This is conducive to improving the problem of material rising and causing filter element blockage, effectively extending the service life of the filter element and reducing the maintenance times of the vacuum loader.
[0006] The technical effects to be achieved by the present invention are achieved through the following technical aspects:
[0007] The utility model provides a vacuum loader with a cyclone separation function, comprising: a material barrel, provided with a feed port for materials to enter the material barrel, a partition structure provided in the material barrel, the partition structure divides the space in the material barrel to form a dust removal chamber and a cyclone chamber, the feed port is connected to the cyclone chamber; a cyclone tube, arranged in the cyclone chamber, one end of the cyclone tube is connected to the cyclone chamber to settle the material, and the other end is connected to the dust removal chamber; a filter element, arranged in the dust removal chamber; and a negative pressure component, arranged on the material barrel, and sucking the gas in the material barrel filtered by the filter element.
[0008] In some implementations, the partition structure includes a partition that divides the space within the bucket.
[0009] In some implementations, the hopper includes a barrel body and a cover body, and the barrel body and the cover body are detachably connected.
[0010] In some implementations, the separation structure further includes a mounting plate disposed between the barrel body and the cover body, the partition plate is disposed on one side of the mounting plate and separates the space inside the barrel body; the filter element passes through the mounting plate, and the negative pressure assembly is disposed on the cover body.
[0011] In some implementations, an air back-blowing assembly is provided on the hopper, and the air back-blowing assembly blows air at the filter element, and the materials blown off at the filter element are deposited in the dust removal chamber. <s
[0012] In some implementations, a plurality of filter elements are provided, and an air back-blowing assembly is provided on the hopper, and the air back-blowing assembly blows the materials on the filter element into the dust removal chamber.
[0013] In some implementations, the air back-blowing assembly includes an air storage tank disposed at the air inlet end of the injection pipe and communicating with the injection pipe; and a fluid control valve disposed on the injection pipe.
[0014] In some implementations, a first discharge port for the materials to fall is formed on the barrel wall of the hopper on the side of the cyclone chamber, and a first discharge assembly for opening or closing the first discharge port is provided at the first discharge port of the hopper.
[0015] In some implementations, the first discharge assembly includes a first discharge plate disposed at the first discharge port and covering or opening the first discharge port; and a first driving member drivingly connected to the first discharge plate, and the first driving member drives the first discharge plate to flip.

[0017] In summary, the present utility model has at least the following advantages:
[0018] For the vacuum feeding machine with a cyclone separation function provided by the present utility model, before the material is conveyed, the negative pressure assembly evacuates the cyclone chamber and the dust removal chamber to form a negative pressure environment in the cyclone chamber and the dust removal chamber. The material enters the cyclone chamber from the feed port, and the separation structure plays a certain blocking role on the material to prevent the material from directly entering the dust removal chamber and adhering to the surface of the filter element. The cyclone pipe settles the material conveyed into the cyclone chamber. Under the suction of the negative pressure assembly, the gas enters the dust removal chamber via the cyclone pipe after settling the material and is filtered by the filter element.
[0019] The separation structure and the setting of the cyclone tube provide multiple barriers to the floating materials, so as to reduce the possibility of the materials adhering to the surface of the filter element under the suction force generated by the negative pressure component. This can effectively alleviate the problem that the lighter materials tend to float upward and cause the filter element to be blocked, thereby extending the service life of the filter element and reducing its maintenance time and frequency, which can ultimately improve the conveying efficiency of the vacuum feeder.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. The described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments.
[0032] Therefore, the following detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the claimed present utility model, but merely represents the selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.
[0033] Example 1:
[0034] Please refer to the attached Figures 1-4 , the vacuum feeding machine with a cyclone separation function of the present utility model can be applied to the processes involving powder production in the chemical industry, food industry, pharmaceutical industry, etc., especially in the production of lithium batteries, and can achieve efficient transportation of powder materials and improve the problem of the filter element 3 being blocked due to material adhesion to the filter element 3.
[0035] Please refer to the attached Figure 1 , the vacuum feeding machine with a cyclone separation function of the present utility model includes a material bucket 1. In a preferred embodiment, the material bucket 1 includes a bucket body 13 and a cover body 14, and the bucket body 13 and the cover body 14 are detachably connected. An inlet 11 for materials to enter the material bucket 1 is provided on the bucket body 13. In some specific embodiments shown, a feeding pipe can be connected to the bucket body 13 at the inlet 11. The feeding pipe is connected to the bucket body 13 and maintains a negative pressure environment for material transfer.
[0036] A partition structure 12 is provided inside the bucket body 13. Please refer to the attached Figure 2 , in a preferred embodiment, the partition structure 12 includes a mounting plate 125, and the mounting plate 125 is specifically a horizontally arranged circular plate. The mounting plate 125 is located between the cover body 14 and the bucket body 13, and the mounting plate 125, the cover body 14, and the bucket body 13 are detachably connected. In some specific embodiments shown, sealing rings are provided on both the side of the mounting plate 125 close to the cover body 14 and the side of the mounting plate 125 close to the bucket body 13. The mounting plate 125 is hermetically connected to the cover body 14 and the bucket body 13 respectively to ensure the sealing performance of the material bucket 1. Further, the mounting plate 125, the cover body 14, and the bucket body 13 can be connected by bolts.
[0037] Please refer to the attached Figures 1-3, in a preferred embodiment, the separation structure 12 includes a partition plate 123. The partition plate 123 is disposed within the barrel body 13 and is connected to the corresponding side of the mounting plate 125. The partition plate 123 is specifically a crescent plate and is welded to the mounting plate 125. It can be understood that this is not a specific limitation on the shape of the partition plate 123, and those skilled in the relevant art can replace it according to the actual material conveying path on this basis. The partition plate 123 divides the space within the barrel body 13 to form a dust removal chamber 121 and a cyclone chamber 122. The feed inlet 11 is in communication with the cyclone chamber 122, and the material enters the cyclone chamber 122 through the feed inlet 11.
[0038] A seal 124 is provided at the edge of the partition plate 123 to ensure a sealed connection between the partition plate 123 and the inner wall of the barrel body 13. The seal 124 is preferably but not limited to a sealing strip, such as a silicone strip. The seal 124 can reduce the possibility that the material enters the dust removal chamber 121 through the gap between the partition plate 123 and the barrel body 13 after entering the cyclone chamber 122 through the feed inlet 11.
[0039] Please refer to Figure 4 , a cyclone tube 2 is provided within the cyclone chamber 122 of the barrel body 13. One end of the cyclone tube 2 is in communication with the cyclone chamber 122, and the other end penetrates through the partition plate 123 and is in communication with the dust removal chamber 121. When the material barrel 1 is evacuated, the gas can enter the dust removal chamber 121 from the cyclone chamber 122 through the cyclone tube 2 and then be discharged from the barrel body 13 through the dust removal chamber 121. When the gas containing the material enters the cyclone tube 2 tangentially at a certain speed, the gas is constrained by the wall of the cyclone tube 2 and undergoes a rotational motion. During the rotation process, the material collides with the wall of the cyclone tube 2 due to inertial centrifugal force and falls along the wall of the cyclone tube 2 under the action of gravity. The material settles in the cyclone chamber 122. The method of cyclone separating the material from the gas is known to those skilled in the art and can be realized, and will not be described in detail in this embodiment.
[0040] Please refer to the attached Figure 1 and Figure 2 , a filter element 3 is penetrated through the cover body 14. In some specific embodiments shown, the filter element 3 is detachably connected to the mounting plate 125. Specifically, the filter element 3 can be assembled with the mounting plate 125 by bolts. One end of the filter element 3 is in communication with the dust removal chamber 121, and the other end is in communication with the cover body 14. The gas in the dust removal chamber 121 can be filtered through the filter element 3 and then introduced into the cover body 14.
[0041] A negative pressure assembly 4 for evacuating the material barrel 1 is provided on the cover body 14, and the negative pressure assembly 4 sucks the gas filtered by the filter element 3 in the material barrel 1. In a preferred embodiment, the negative pressure assembly 4 includes a ventilation pipe 41, which is connected to and detachably connected to the material barrel 1. Specifically, a sealing ring is provided between the ventilation pipe 41 and the cover body 14 and they are connected by a clamp. A negative pressure valve 42 and an exhaust valve 43 are provided on the ventilation pipe 41. When the negative pressure valve 42 is opened, the exhaust valve 43 is closed, and the gas in the material barrel 1 is discharged through the ventilation pipe 41, creating a negative pressure environment in the material barrel 1.
[0042] During material transportation, the negative pressure assembly 4 sucks the gas in the material barrel 1. Under the suction of the negative pressure assembly 4, the material is transported by the airflow from the feed port 11 to the cyclone chamber 122 of the barrel body 13 and enters the cyclone pipe 2. The cyclone pipe 2 can settle the material carried in the airflow to separate the material. The airflow continues to enter the dust removal chamber 121 along the cyclone pipe 2 and is filtered by the filter element 3. After being filtered by the filter element 3, the airflow enters the cover body 14 and is then sucked by the negative pressure assembly 4 to be discharged from the material barrel 1. The partition structure 12 can prevent the contact between the airflow containing the material and the filter element 3. The airflow containing the material first separates the material through the cyclone pipe 2, so that the material with a lighter specific gravity can also settle in the cyclone chamber 122, thus improving the problem of the filter element 3 being blocked due to the upward movement of the material, effectively extending the service life of the filter element 3 and reducing the maintenance frequency of the vacuum feeder. The operator does not need to frequently replace and maintain the filter element 3, which is beneficial to improving production efficiency.
[0043] Embodiment 2:
[0044] The difference between this embodiment and Embodiment 1 is that the vacuum feeder with a cyclone separation function in this embodiment further includes a backflush assembly 31 for cleaning the filter element 3. Please refer to Figure 1 and Figure 5 .
[0045] The backflush assembly 31 blows air towards the filter element 3 to blow off the material adhering to the surface of the filter element 3, and the blown-off material deposits in the dust removal chamber 121. In a preferred embodiment, the backflush assembly 31 includes a blowpipe 311, which passes through the side wall of the cover body 14 and is located above the filter element 3. The air outlet end of the blowpipe 311 is arranged opposite to the filter element 3 so that the blowpipe 311 blows air towards the filter element 3.
[0046] In some specific embodiments shown, several filter elements 3 are provided to improve the dust removal efficiency. The blowpipe 311 is arranged corresponding to the filter element 3. A gas storage tank 313 is provided on one side of the air inlet end of the blowpipe 311. The gas storage tank 313 is detachably connected to the barrel body 13. Specifically, the gas storage tank 313 can be assembled on the outer wall of the barrel body 13 through bolts. Further, a manual ball valve can be provided on the gas storage tank 313. After the backflush assembly 31 works for a long time, the gas storage tank 313 discharges water through the manual ball valve to ensure the normal operation of the backflush assembly 31.
[0047] A fluid control valve 312 is provided between the injection pipe 311 and the gas storage tank 313. Specifically, a hose is provided between one end of the fluid control valve 312 and the injection pipe 311, and the other end is connected to the interface of the gas storage tank 313. When the fluid control valve 312 is opened, the gas in the gas storage tank 313 is blown through the hose and the injection pipe 311 towards the filter element 3, and the materials adhered to the surface of the filter element 3 settle in the dust removal chamber 121. The setting of the backwashing assembly 31 can further protect the filter element 3 and reduce the possibility of flying materials adhering to the filter element 3. Specifically, the gas storage tank 313 intermittently blows air to multiple filter elements 3 through the call of the fluid control valve 312, and the backwashing assembly 31 blows air to multiple filter elements 3 repeatedly in turn. Some of the multiple filter elements 3 are backwashed and cleaned while some are used for gas filtration, and the filter element 3 can continuously remove dust.

[0057] Further, sensors may be provided on the barrel body 13 in the cyclone chamber 122 and the dust removal chamber 121. After the sensors sense that the materials in the dust removal chamber 121 and the cyclone chamber 122 accumulate to a certain extent, the first driving member 162 drives the first connecting rod 164 to rotate to drive the first discharge plate 161 to open the first discharge port 15, and the materials are discharged at the cyclone chamber 122.
