Description

Technical Field

[0001] This utility model belongs to the field of irradiation sterilization technology, and specifically relates to an irradiation sterilization device for granular agricultural products. Background Technology

[0002] Agricultural products are susceptible to microbial contamination during production and storage, which can affect their efficacy and safety. Therefore, effective sterilization of agricultural products is crucial. In recent years, irradiation sterilization technology has been widely used in the sterilization of agricultural products due to its advantages such as high efficiency, environmental friendliness, and residue-free processing.

[0003] In the prior art, a device for surface insecticidal and sterilizing granular agricultural products is disclosed, with publication number CN208175914U; application date: 2018-05-21; publication date: 2018-12-04. It includes: a feeding unit for outputting the material to be irradiated, causing it to fall along a parabolic trajectory under gravity; and a collection unit, located at a preset position to collect the agricultural products after electron beam irradiation. An electron beam generator is located on one side of the falling trajectory of the agricultural products, and a reflective magnet, cooperating with the electron beam generator, is located on the other side of the falling trajectory to reflect the electron beam passing through the gaps in the agricultural products, achieving electron irradiation on both sides of the agricultural products. Its drawback is that when the height difference between the feeding unit and the collection unit is large, granular agricultural products such as soybeans and coffee beans collide with the inner wall of the collection unit during the fall, causing the material to break and compromising its integrity, thus affecting its effectiveness. Utility Model Content

[0004] The purpose of this invention is to provide a device for killing insects and sterilizing the surface of granular agricultural products, which can slow down the falling speed of the material and prevent the material from falling directly vertically into the collection unit, thereby ensuring the integrity of the material.

[0005] The purpose of this utility model is achieved as follows: A sterilization device for granular agricultural products by irradiation includes an irradiation platform and an irradiation accelerator. The irradiation platform includes an inclined irradiation plane and a shell. A diversion mechanism is provided at the highest point of the irradiation plane to guide the granular material to feed in several different directions. A flow guiding mechanism is provided at the lowest point of the irradiation plane to guide the granular material to fall in the same direction. The shell has an irradiation window corresponding to the electron accelerator. Several protruding deceleration components are provided on the irradiation plane corresponding to the irradiation window.

[0006] In use, the material, under the action of the diversion mechanism, falls slowly along the irradiation plane in different feeding directions. The electron beam emitted by the irradiation accelerator irradiates the falling agricultural products through the irradiation window. After sterilization, the material, under the action of the guiding mechanism, is collected in the same falling direction into the external collection unit. Compared with the prior art, the beneficial effects of this invention are: the diversion mechanism can prevent the material from gathering in one place, so that the falling material is in a dispersed state, which can improve the irradiation effect; the protruding deceleration component can slow down the falling speed of the material on the one hand, and change the rolling direction of the granular material on the other hand, thereby further improving the dispersion of the material; during the rolling process of the granular material on the irradiation plane, it continuously changes its orientation towards the irradiated surface of the irradiation accelerator, thereby further improving the overall sterilization effect of the granular material.

[0007] As a further improvement of this utility model, a titanium window and titanium foil are provided corresponding to the irradiation window.

[0008] As a further improvement of this utility model, an exciter is provided at the bottom of the irradiation plane.

[0009] As a further improvement of this utility model, the irradiation accelerator is arranged parallel to the irradiation plane so that the electron beam emitted by the irradiation accelerator is perpendicular to the irradiation plane.

[0010] As a further improvement of this utility model, the speed reducer is a cylindrical speed reducer rod, which is arranged perpendicular to the irradiation plane.

[0011] As a further improvement of this utility model, the diversion mechanism includes two diversion baffles that are symmetrically distributed with each other.

[0012] As a further improvement of this utility model, the drainage mechanism includes two drainage plates that are symmetrically distributed with each other.

[0013] As a further improvement of this utility model, the highest point of the shell is provided with a feed inlet and the lowest point is provided with a discharge outlet, both of which are elongated flat openings.

[0014] As a further improvement of this utility model, it also includes a storage bin, wherein a discharge port is provided at the lowest point of the storage bin, and the discharge port is connected to the inlet through an arc-shaped chute.

[0015] As a further improvement of this utility model, a discharge control valve is provided corresponding to the discharge port. Attached Figure Description

[0017] Figure 2 This is a front view of the irradiation plane of this utility model.

[0018] The components include: 1. Storage bin; 101. Discharge port; 2. Irradiation station; 201. Irradiation plane; 202. Shell; 4. Vibrator; 203. Irradiation window; 204. Titanium window and titanium foil; 205. Feed inlet; 206. Discharge port; 207. Deceleration lever; 208. Drainage baffle; 209. Drainage plate; 3. Irradiation accelerator; 5. Arc-shaped chute; and 6. Discharge control valve. Detailed Implementation

[0019] like Figure 1 The diagram shows an irradiation sterilization device for granular agricultural products, comprising a storage bin 1, an irradiation table 2, and an irradiation accelerator 3. The irradiation table 2 includes an inclined irradiation plane 201 and a housing 202. A diversion mechanism is provided at the highest point of the irradiation plane 201 to guide the granular material to feed in several different directions. A guide mechanism is provided at the lowest point of the irradiation plane 201 to guide the granular material to fall in the same direction. A vibrator 4 is provided at the bottom of the irradiation plane 201. The vibrator 4 is an existing device attached to the equipment to generate excitation force. The device includes: a housing 202 with an irradiation window 203 corresponding to the electron accelerator, and a titanium window and titanium foil 204 corresponding to the irradiation window 203; a deceleration component evenly distributed on the irradiation plane 201 corresponding to the irradiation window 203; a feed inlet 205 at the highest point of the housing 202 and a discharge outlet 206 at the lowest point, preferably elongated and flat; a discharge outlet 101 at the lowest point of the storage bin 1, which is connected to the feed inlet 205 via an arc-shaped chute 5; and a discharge control valve 6 corresponding to the discharge outlet 101.

[0020] To improve the utilization efficiency of the electron beam, the irradiation accelerator 3 is arranged parallel to the irradiation plane 201 so that the electron beam emitted by the irradiation accelerator 3 is perpendicular to the irradiation plane 201. In this embodiment, the deceleration component is a cylindrical deceleration rod 207, which can prevent it from scratching agricultural products. The deceleration rod 207 is arranged perpendicular to the irradiation plane 201. The diversion mechanism includes two symmetrically distributed diversion baffles 208. The diversion mechanism includes two symmetrically distributed diversion plates 209.

[0021] When this utility model is in use, the discharge control valve 6 is opened, and the material falls from the bottom of the storage bin 1 into the arc-shaped chute 5. Then, guided by the arc-shaped chute 5, it enters the irradiation station 2 from the feed inlet 205. Two guide baffles 208 divert the material gathered at the feed inlet 205 to three conveying channels in different directions. Due to the obstruction of the baffles, the material on both sides has a slightly lower feed speed than the material in the middle. The granular material in each conveying channel falls slowly along the irradiation plane 201 area. The irradiation accelerator 3 irradiates the falling material simultaneously. Finally, all the granular material is discharged from the discharge port 206 under the guidance of the two guide plates 209. The advantages of this utility model are as follows: the material discharge speed can be adjusted by the discharge control valve 6 to avoid material accumulation at the feed inlet 205, and the material accumulation on the irradiation plane 201 can be avoided by starting the vibrator 4. The operation is simple and convenient, and the purpose of continuous irradiation treatment of materials is achieved. By setting titanium windows and titanium foils 204, both electron beams can pass through and the sealing performance of the device can be guaranteed, so that the material is always isolated from the external bacterial environment during the process of being transferred from the storage bin 1 to the irradiation table 2, further ensuring its sterilization quality.

[0022] This utility model is not limited to the above embodiments. Based on the technical solutions disclosed in this utility model, those skilled in the art can make some substitutions and modifications to some of the technical features without creative labor, and these substitutions and modifications are all within the protection scope of this utility model.
