Description

A rapeseed surface dust removal device Technical Field

[0001] This utility model relates to the field of rapeseed processing technology, and in particular to a rapeseed surface dust removal device. Background Technology

[0002] Rapeseed is easily contaminated with dust and other dirt during production and processing. In order to ensure the purity of the product, rapeseed needs to be cleaned.

[0003] A search revealed a prior art rapeseed screening and dust removal device (publication number: CN218691282U), comprising a device housing, mounting plates on both outer sides of the housing, a blower mounted on the upper end of the mounting plates, a rapeseed screening disc mounted inside the housing, the lower end of the rapeseed screening disc slidably connected to the inner wall of the housing via a sliding groove, six water spray boxes surrounding the upper outer side of the housing, and a heater mounted on the outer side of the housing, with resistance heating tubes mounted on the inner wall of the heater, a servo motor mounted at the lower end of the housing, and a rotating shaft mounted on the upper end of the servo motor, the rotating shaft being fixedly connected to the rapeseed screening disc via a locking ring.

[0004] Existing technologies use physical stirring combined with a fan blowing from above the outer casing to remove floating dust. However, the stirring effect is limited, especially given the small size and smooth surface of rapeseed grains. Dust on the surface of the bottom rapeseed grains is difficult to remove by the airflow from the fan, thus limiting the dust removal effect and leaving room for optimization.

[0005] Therefore, we propose a surface dust removal device for rapeseed. Summary of the Invention

[0006] The present invention mainly addresses the technical problem of poor dust removal effect on rapeseed, and provides a rapeseed surface dust removal device.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a rapeseed surface dust removal device, comprising:

[0008] The outer shell has material inlets at both the top and bottom, and the interior of the outer shell has a rotating stirring rod for turning the material.

[0009] An air blowing assembly is installed inside the cavity of the outer casing to remove dust. The air blowing assembly includes an air plate, spray holes, a baffle, and a fan. The air plate is fixedly connected to the outer casing, and the baffle is rotatably connected to the air plate. Several spray holes are opened on the top of the air plate. The stirring rod can push the baffle to block the spray holes. The fan is fixedly installed outside the outer casing and can deliver air to the air plate.

[0010] In a preferred embodiment of this utility model, the air plate is formed into a hollow cylinder, and the exhaust port of the fan is fixedly connected to a connecting pipe, which passes through the air plate and extends into the air plate cavity.

[0011] In a preferred embodiment of this utility model, at least three sets of injection holes are provided on the top of the air disc, and multiple injection holes in the same set are distributed in a fan shape.

[0012] In a preferred embodiment of this utility model, the baffle is formed into a circular plate, a sealing gasket is provided at the bottom of the baffle, several fan-shaped grooves are opened at the top of the baffle, a rotating shaft is fixedly connected to the bottom of the baffle, the rotating shaft passes through the air plate and extends into the cavity of the air plate, and a torsion spring is fixedly connected to the rotating shaft.

[0013] In a preferred embodiment of this invention, the air blowing assembly further includes a deformation rod, which is fixedly connected to a baffle, and the stirring rod can push the deformation rod to cause the baffle to rotate.

[0014] In a preferred embodiment of this utility model, the deformation rod forms an L-shaped folded plate, and the deformation rod extends obliquely toward the center of the baffle.

[0015] In a preferred embodiment of this utility model, an exhaust pipe is fixedly installed on the top of the outer shell, and a collection cylinder is fixedly installed on the side wall of the outer shell. A dust removal bag is provided inside the collection cylinder, and the exhaust pipe passes through the collection cylinder and extends into the cavity of the collection cylinder.

[0016] Beneficial effects

[0017] This utility model provides a device for removing dust from the surface of rapeseed. It has the following beneficial effects:

[0018] 1. This rapeseed surface dust removal device uses a stirring rod to agitate the rapeseed grains, and a blower to blow air into the air plate cavity, which is then sprayed out from various spray holes. Through aeration combined with material agitation, the rapeseed is squeezed against each other to remove surface dust. The stirring rod can intermittently push the baffle to rotate and block some of the spray holes, resulting in differences in the airflow velocity from the spray holes, achieving a pulse aeration effect, which intensifies the relative movement of the rapeseed within the shell and improves the dust removal effect.

[0019] 2. This rapeseed surface dust removal device, through a deformation rod fixedly connected to a baffle, the crossbar gradually contacts the top of the baffle. As the crossbar moves in a circle, the crossbar applies a circumferential thrust to the deformation rod and gradually separates from the deformation rod, thereby intermittently pushing the baffle and causing the spray hole to intermittently exhaust air to achieve an aeration effect.

[0020] 3. This rapeseed surface dust removal device discharges rising airflow through an exhaust pipe. The rising airflow carries dust into a collection cylinder, where it is collected by a dust filter bag. The air is then discharged, achieving a good dust removal effect without causing dust to overflow and affect air quality. Attached Figure Description

[0027] A rapeseed surface dust removal device, as shown in Figures 1 and 2, includes:

[0028] The outer casing 10 has a material inlet at both the top and bottom. Inside the outer casing 10, there is a rotating stirring rod 11 for turning the material. A motor is fixedly installed at the top of the outer casing 10, and the output shaft of the motor is fixedly connected to the stirring rod 11. The stirring rod 11 includes a main shaft, and several crossbars are fixedly installed on the main shaft. Spiral blades are fixedly installed on the crossbars for turning the material.

[0029] As shown in Figures 2, 3, 4, and 5, the air blowing assembly is installed inside the cavity of the outer casing 10 to discharge dust. The air blowing assembly includes an air plate 12, injection holes 13, a baffle 14, and a fan 16. The air plate 12 is fixedly connected to the outer casing 10, and the baffle 14 is rotatably connected to the air plate 12. Several injection holes 13 are opened on the top of the air plate 12. The stirring rod 11 can push the baffle 14 to block the injection holes 13. The fan 16 is fixedly installed outside the outer casing 10 and can deliver air to the air plate 12. The air plate 12 is a hollow cylinder, and the exhaust port of the fan 16 is... A connecting pipe is fixedly connected, which passes through the air plate 12 and extends into the cavity of the air plate 12. At least three sets of injection holes 13 are opened on the top of the air plate 12. Multiple injection holes 13 in the same set are distributed in a fan shape. The baffle 14 forms a circular plate. A sealing gasket is provided at the bottom of the baffle 14. Several fan-shaped grooves are opened on the top of the baffle 14. A rotating shaft is fixedly connected to the bottom of the baffle 14. The rotating shaft passes through the air plate 12 and extends into the cavity of the air plate 12. A torsion spring is fixedly connected to the rotating shaft. A stop block is also provided on the top of the air plate 12. The torque of the torsion spring to the rotating shaft causes one side of the baffle 14 to abut against the stop block.

[0030] In this scheme, the rapeseed grains are mainly agitated by the stirring rod 11, and the blower 16 blows air into the air plate 12 cavity, and then sprays it out from each spray hole 13. The aeration method combined with the stirring of the material makes the rapeseed squeeze each other to remove the surface dust. The stirring rod 11 can intermittently push the baffle 14 to rotate and block some of the spray holes 13, so that the airflow velocity of the spray holes 13 is different, achieving a pulse aeration effect, which intensifies the relative movement of the rapeseed in the outer shell 10 and improves the dust removal effect.

[0031] As shown in Figure 4, the air blowing assembly also includes a deformation rod 15, which is fixedly connected to the baffle 14. The stirring rod 11 can push the deformation rod 15 to rotate the baffle 14 by a certain angle. The deformation rod 15 forms an L-shaped folded plate and extends inclined towards the center of the baffle 14. In order to realize that the crossbar of the stirring rod 11 pushes the baffle 14 to rotate, the crossbar gradually contacts the top of the baffle 14 through the deformation rod 15 fixedly connected to the baffle 14. As the crossbar moves in a circle, the crossbar applies a circumferential thrust to the deformation rod 15 and gradually separates from the deformation rod 15, thereby realizing the intermittent pushing of the baffle 14 and causing the injection hole 13 to intermittently exhaust air to achieve the aeration effect.

[0032] As shown in Figure 1, an exhaust pipe 20 is fixedly installed on the top of the outer shell 10, and a collection cylinder 21 is fixedly installed on the side wall of the outer shell 10. A dust removal bag is provided inside the collection cylinder 21, and the exhaust pipe 20 passes through the collection cylinder 21 and extends into the cavity of the collection cylinder 21.

[0033] As a supplement to the above solution, the dust collection bag can be a cloth bag. The rising airflow is discharged through the exhaust pipe 20. The rising airflow will carry dust into the collection cylinder 21. The dust is collected by the dust collection bag in the collection cylinder 21 and the air is discharged. While achieving a good dust removal effect, it will not cause dust to overflow and affect the air quality.

[0034] The working principle of this utility model is as follows: A motor is fixedly installed on the top of the outer shell 10. The output shaft of the motor is fixedly connected to the stirring rod 11. The stirring rod 11 includes a main shaft, and several crossbars are fixedly installed on the main shaft. Spiral blades are fixedly installed on the crossbars for turning the material. The stirring rod 11 turns the rapeseed particles. The blower 16 blows air into the air plate 12 cavity, and then sprays it out from each spray hole 13. Through aeration and material stirring, the rapeseed particles are squeezed together to remove surface dust. The stirring rod 11 can intermittently push the baffle 14 to rotate, blocking some of the spray holes 13, so that the spray... The airflow velocity of the jets from the orifice 13 varies. Through the deformation rod 15 fixedly connected to the baffle 14, the crossbar gradually contacts the top of the baffle 14. As the crossbar moves in a circle, it applies a circumferential thrust to the deformation rod 15 and gradually separates from the deformation rod 15, thus intermittently pushing the baffle 14. The baffle 14 can intermittently block the jet orifice 13, achieving a pulse-type aeration effect, promoting the separation of rapeseed particles and dust. The exhaust pipe 20 discharges the rising airflow, which carries dust into the collection cylinder 21. The dust is collected by the dust filter bag inside the collection cylinder 21.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
