Description

Technical Field

[0001] This utility model relates to the technical field of dust removal bins in storage silos, specifically a centrifugal grain dust removal bin. Background Technology

[0002] In the prior art, grains and cereals contain a lot of particulate dust, so it is necessary to remove the particulate dust from the grains and cereals. The prior art usually uses the method of grain dust removal to remove dust particles. For example, the "Dust Removal Equipment for Grain Storage" disclosed in Publication (Announcement) No.: CN208033039U mainly uses the cooperation of auger assembly and dust removal fan to achieve material dust removal, and is equipped with technical structures such as discharge pipe and feed pipe to facilitate the overall material storage process.

[0003] For example, the "Grain Dust Removal Device for Grain Processing" disclosed in Publication No. CN110743861A includes a support box. Connecting plates are fixed to both sides of the outer wall of the support box, and electric telescopic rods are installed on the bottom outer walls of the connecting plates. Support feet are installed on the bottom outer walls of the electric telescopic rods. Universal wheels are installed at the four corners of the bottom outer wall of the support box. An L-shaped support plate is installed on one side of the outer wall of the support box. A partition chamber is fixed to the top outer wall of the support box, and a filtration mechanism is installed on the inner wall of the partition chamber. A dust collection mechanism is installed on the top outer wall of the L-shaped support plate, and a humidification mechanism is installed on one side of the outer wall of the L-shaped support plate. The filtration mechanism includes a filter screen. This invention, by incorporating connecting plates, electric telescopic rods, and support feet, allows for adjustment of the length of the electric telescopic rods to ensure the support feet touch the ground, thereby improving the stability of the device. Adjusting the length of the electric telescopic rods to ensure the universal wheels touch the ground allows for rapid movement of the device.

[0004] The above-mentioned technical solution using the auger assembly requires the installation of an auger that occupies a large space. The overall structure occupies a large space and cannot complete the dust removal work in a small area. In addition, the separation of materials and particulate dust in the overall structure is cumbersome and unreasonable. Existing equipment can sometimes only remove some heavy dust particles, while some heavier particles cannot be effectively removed. Moreover, it usually only has one removal mechanism, which cannot complete the dust removal work with high quality and efficiency.

[0005] Therefore, in order to solve the above problems, it is necessary to develop a centrifugal grain dust removal bin with a reasonable structure that can improve the quality and efficiency of dust removal. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a centrifugal grain dust removal bin; its technical solution is as follows:

[0007] A centrifugal grain dust removal bin includes a support base, on which a centrifugal motor is installed at the middle position. The main shaft of the centrifugal motor extends upward, and a centrifugal shroud is installed at the shaft end. The centrifugal shroud is U-shaped, and a vertical centrifugal plate is provided at the upper end of the centrifugal shroud. The upper end of the centrifugal shroud is open. The centrifugal shroud rotates under the drive of the centrifugal motor, causing the material placed inside to generate centrifugal force.

[0008] Above the centrifuge enclosure, a storage enclosure is also provided. The storage enclosure is in the shape of a cover. A storage area is provided around the outer edge of the storage enclosure. An inner vertical plate is provided on the inner side of the storage area. The inner vertical plate corresponds to the centrifuge vertical plate and there is a rotation gap between the inner vertical plate and the centrifuge vertical plate. The inner vertical plate is fixedly installed so as not to hinder the rotation of the centrifuge vertical plate. A discharge gap is provided between the upper ends of the centrifuge vertical plate and the inner vertical plate and the upper inner wall of the storage enclosure.

[0009] The upper end of the storage hood is also equipped with a dust collection device. When the material inside the centrifuge hood rotates under the action of the centrifuge motor, the dust collection device adsorbs the particulate dust inside the centrifuge hood.

[0010] Furthermore, a dust collection filter is also installed on the dust collection device.

[0011] Furthermore, a feed pipe is provided at the upper end of the storage hood, and a discharge pipe is also installed on the side wall of the storage area on both sides of the storage hood; and there are four evenly spaced discharge pipes in total.

[0012] Furthermore, the support base is also equipped with a support ramp for supporting the centrifuge hood, and a support platform for supporting and fixing the storage hood is also provided around the outer edge of the support base.

[0013] Furthermore, the support slope of the support base is provided with several evenly spaced support grooves. The support grooves are semi-circular groove structures, and each support groove contains a corresponding circular support ball, which supports the centrifugal cover above.

[0014] Furthermore, the upper end of the centrifugal vertical plate is also provided with a baffle plate that extends outward and downward. The baffle plate accordingly blocks the rotation gap and the inner vertical plate of the storage area. When the centrifugal hood rotates, it drives the baffle plate to rotate, and the inner vertical plate will not affect the rotation of the baffle plate.

[0015] Furthermore, the storage area is also equipped with several material drop plates that are inclined from top to bottom, and the fixed ends of adjacent material drop plates are staggered left and right, so that the path of the material falling is an S-shaped structure.

[0016] Furthermore, a vertically arranged dust collection device is installed on the outer wall of the storage area to remove dust particles from the material falling from the discharge plate; and the dust collection device is also equipped with a dust collection filter.

[0017] Beneficial effects: This utility model has the following beneficial effects:

[0018] 1) This device uses a centrifugal structure to remove dust. The centrifugal motor drives the centrifugal shroud to rotate, which lifts the dust inside the shroud and then extracts the dust. This effectively saves the overall space of the device and has a reasonable structure.

[0019] 2) This device can achieve dust removal and material storage by controlling the speed of the centrifugal motor. During dust removal, the speed of the centrifugal motor is designed to be moderate so that the material will not exceed the height of the centrifugal vertical plate. After the centrifugal dust removal is completed, the speed of the centrifugal motor is increased so that the material can exceed the height of the centrifugal vertical plate under the action of centrifugal force. The material enters the storage area from the storage gap and is stored. The structure is ingenious.

[0020] 3) The device has a reasonable arrangement of the positions of the centrifugal vertical plate, the side vertical plate, the rotation gap and the baffle plate, so that the material can enter the outer storage area from the storage gap relatively smoothly and conveniently.

[0021] 4) The device has a reasonably designed support base structure, which can reasonably support the centrifuge hood and the storage hood;

[0022] 5) This device also includes a material discharge plate and a corresponding dust collection device in the material storage area. The material falling on the material discharge plate is subjected to secondary dust removal by the dust collection device, which effectively improves the dust removal quality and efficiency.

Detailed Implementation

[0028] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. These embodiments are implemented under the premise of the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0029] Example 1

[0030] like Figure 1 and Figure 2 As shown, a centrifugal grain dust removal bin of this embodiment includes a support base 1, on which a centrifugal motor 2 is provided at the middle position; the main shaft of the centrifugal motor 2 extends upward, and a centrifugal cover 3 is installed at the shaft end of the main shaft. The centrifugal cover 3 is configured with a U-shaped structure, and a vertical centrifugal plate 4 is provided at the upper end of the centrifugal cover 3. In this embodiment, the upper end of the centrifugal cover 3 is open. The centrifugal cover 3 rotates under the drive of the centrifugal motor 2, causing the material placed inside to generate centrifugal force.

[0031] In this embodiment, a storage cover 5 is also provided above the centrifuge cover 3. The storage cover 5 is generally in the shape of a cover. A storage area 6 is provided around the outer edge of the storage cover 5. An inner vertical plate 7 is provided on the inner side of the storage area 6. In this embodiment, the inner vertical plate 7 corresponds to the centrifuge vertical plate 4, and a rotation gap 8 is left between the inner vertical plate 7 and the centrifuge vertical plate 4. The inner vertical plate 7 is fixedly installed and does not hinder the rotation of the centrifuge vertical plate 4. A discharge gap 9 is left between the upper ends of the centrifuge vertical plate 4 and the inner vertical plate 7 and the upper inner wall of the storage cover 5.

[0032] In this embodiment, a dust collection device 10 is also installed at the upper end of the storage hood 5. When the material inside the centrifuge hood 3 rotates under the action of the centrifuge motor 2, the dust collection device 10 adsorbs the particulate dust inside the centrifuge hood 3.

[0033] In this embodiment, a dust collection filter 11 is also installed on the dust collection device 10.

[0034] In this embodiment, a feed pipe 51 is provided at the upper end of the storage hood 5, and a discharge pipe 12 is also installed on the side wall of the storage area 6 on both sides of the storage hood 5; and in this embodiment, there are four evenly spaced discharge pipes 12.

[0035] In this embodiment, a support ramp 13 for supporting the centrifugal hood 3 is also installed on the support base 1, and a support platform 14 for supporting and fixing the storage hood 5 is also provided around the outer edge of the support base 1.

[0036] The support base 1 of this embodiment is provided with a number of evenly spaced support grooves 15 on the support slope 13. The support grooves 15 of this embodiment are semi-circular groove structures, and a circular support ball 16 is placed in each support groove 15. The centrifugal cover 3 above is supported by the support ball 16 of this embodiment.

[0037] In this embodiment, the upper end of the centrifugal vertical plate 4 is also provided with a baffle plate 17 that extends outward and downward. In this embodiment, the baffle plate 17 correspondingly blocks the rotation gap 8 and the inner vertical plate 7 of the storage area 6; and when the centrifugal cover 3 rotates, it drives the baffle plate 17 to rotate, and the inner vertical plate 7 will not affect the rotation of the baffle plate 17.

[0038] The technical solution of this embodiment differs from the traditional technical solution that uses conveyor belts or auger mechanisms for dust removal. The technical solution of this embodiment achieves dust removal through centrifugal force. In this embodiment, when the centrifugal motor rotates, the material placed inside the centrifugal hood will rotate along with it. Some lighter dust particles will gradually float up during the rotation, and the dust collection device installed on the centrifugal hood can adsorb these particles. However, since the material has a large mass, it can only be lifted to a certain height by centrifugation and therefore will not be adsorbed by the dust collection device. Furthermore, since there is a dust collection filter, the material will not be adsorbed.

[0039] During the above process, it is necessary to control the speed of the centrifugal motor accordingly. The speed should not be too fast so that the internal material does not exceed the height of the centrifugal vertical plate and does not enter the outer storage area. After the dust particles are extracted, the speed of the centrifugal motor is increased by controlling the speed of the centrifugal motor so that the material that has been dusted can exceed the height of the centrifugal vertical plate under the action of centrifugal force and enter the outer storage area from the discharge gap, thus completing the centrifugal material dust removal work.

[0040] In this embodiment, the outer storage hood completely covers the inner centrifuge hood, and the inner vertical plate is positioned to correspond with the centrifuge vertical plate to facilitate the entry of materials. However, a rotation gap is left between the two. Therefore, an inclined baffle is also provided at the upper end of the centrifuge vertical plate in this device. The baffle can effectively block the rotation gap, so that the materials will not fall into the rotation gap when they come out of the discharge gap. The overall structure is reasonable.

[0041] In addition, this embodiment also focuses on the structure of the support base. First, the centrifugal motor needs to drive the entire centrifugal housing to rotate. However, the overall structure of the centrifugal housing is relatively large, and relying solely on the centrifugal motor for support would pose certain safety hazards. In this embodiment, a support ramp is set on the support base, and a support groove and support ball bearings are installed on the support ramp. The centrifugal housing is supported by the support ramp and support ball bearings, making the overall structure more reasonable. In addition, a support platform is also set on the support base to support and fix the outer storage area, which is also reasonable.

[0043] like Figure 3 and Figure 4 As shown, a centrifugal grain dust removal bin of this embodiment includes a support base 1, on which a centrifugal motor 2 is provided at the middle position; the main shaft of the centrifugal motor 2 extends upward, and a centrifugal cover 3 is installed at the shaft end of the main shaft. The centrifugal cover 3 is configured with a U-shaped structure, and a vertical centrifugal plate 4 is provided at the upper end of the centrifugal cover 3. In this embodiment, the upper end of the centrifugal cover 3 is open. The centrifugal cover 3 rotates under the drive of the centrifugal motor 2, causing the material placed inside to generate centrifugal force.

[0044] In this embodiment, a storage cover 5 is also provided above the centrifuge cover 3. The storage cover 5 is generally in the shape of a cover. A storage area 6 is provided around the outer edge of the storage cover 5. An inner vertical plate 7 is provided on the inner side of the storage area 6. In this embodiment, the inner vertical plate 7 corresponds to the centrifuge vertical plate 4, and a rotation gap 8 is left between the inner vertical plate 7 and the centrifuge vertical plate 4. The inner vertical plate 7 is fixedly installed and does not hinder the rotation of the centrifuge vertical plate 4. A discharge gap 9 is left between the upper ends of the centrifuge vertical plate 4 and the inner vertical plate 7 and the upper inner wall of the storage cover 5.

[0045] In this embodiment, a dust collection device 10 is also installed at the upper end of the storage hood 5. When the material inside the centrifuge hood 3 rotates under the action of the centrifuge motor 2, the dust collection device 10 adsorbs the particulate dust inside the centrifuge hood 3.

[0046] In this embodiment, a dust collection filter 11 is also installed on the dust collection device 10.

[0047] In this embodiment, a feed pipe 51 is provided at the upper end of the storage hood 5, and a discharge pipe 12 is also installed on the side wall of the storage area 6 on both sides of the storage hood 5; and in this embodiment, there are four evenly spaced discharge pipes 12.

[0048] In this embodiment, a support ramp 13 for supporting the centrifugal hood 3 is also installed on the support base 1, and a support platform 14 for supporting and fixing the storage hood 5 is also provided around the outer edge of the support base 1.

[0049] The support base 1 of this embodiment is provided with a number of evenly spaced support grooves 15 on the support slope 13. The support grooves 15 of this embodiment are semi-circular groove structures, and a circular support ball 16 is placed in each support groove 15. The centrifugal cover 3 above is supported by the support ball 16 of this embodiment.

[0050] In this embodiment, the upper end of the centrifugal vertical plate 4 is also provided with a baffle plate 17 that extends outward and downward. In this embodiment, the baffle plate 17 correspondingly blocks the rotation gap 8 and the inner vertical plate 7 of the storage area 6; and when the centrifugal cover 3 rotates, it drives the baffle plate 17 to rotate, and the inner vertical plate 7 will not affect the rotation of the baffle plate 17.

[0051] In this embodiment, the storage area 6 is also equipped with several material drop plates 18 that are inclined from top to bottom, and the fixed ends of the adjacent material drop plates 18 are staggered from left to right, so that the path of the material falling is an S-shaped structure.

[0052] In this embodiment, a vertically arranged dust collection device 10 is also installed on the outer wall of the storage area 6. The dust collection device 10 removes dust particles from the material falling from the material drop plate 18; and the dust collection device 10 is also equipped with a dust collection filter 11.

[0053] The technical solution of this embodiment is based on the technical solution of embodiment 1. A drop plate is set at the location of the storage area, so that the material entering from the storage gap falls onto the drop plate and then falls down from the drop plate in an S-shape. At the same time, a vertical dust collection device is installed on the outer wall of the storage area. When the material falls down in an S-shape on the drop plate, the vertical dust collection device performs dust collection on the material. The secondary dust removal work of the material can be completed through the design of the outer drop plate, which effectively improves the dust removal effect and quality.
