[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0034] The existing culture medium material conveying mechanism uses air cooling, and its airflow easily blows away the culture medium, which is not conducive to the normal transportation of the culture medium material; secondly, the cooling efficiency of air cooling is greatly affected by the ambient temperature. In a high temperature environment, the air cooling effect is poor.
[0035] In order to solve the above technical problems, this embodiment provides a base material transmission device for high energy electron beam irradiation, please refer to Figures 1 to 3 As shown, Figure 1 is a stereoscopic diagram of a base material transport device for high-energy electron beam irradiation in an embodiment, Figure 2 is a bottom view of a base material transport device for high-energy electron beam irradiation in an embodiment, Figure 3 for Figure 2 Schematic diagram of section A.
[0036] The base material transmission device for high-energy electron beam irradiation of this embodiment includes: a frame 1, a conveying mechanism 2 and a cooling mechanism 3.
[0037] like Figure 1 As shown, the frame 1 serves as a mounting carrier for the conveying mechanism 2 and the cooling mechanism 3 and is fixed relative to the ground.
[0038] like Figure 3 As shown, the conveying mechanism 2 includes a motor 21, a driving shaft 22, a driven shaft 23 and a conveyor belt 24. The driving shaft 22 and the driven shaft 23 are respectively rotatably connected to the frame 1 and are arranged in parallel and at intervals. The driving shaft 22 and the driven shaft 23 are provided with axially penetrating cooling channels 200. The motor 21 is arranged on the frame 1 and is transmission-connected to the driving shaft 22. The conveyor belt 24 is in contact with the outer surfaces of the driving shaft 22 and the driven shaft 23 and is transmission-connected, and a high-energy electron beam irradiation device is provided above it.
[0039] like Figure 3 As shown, the cooling mechanism 3 includes a cooling pipe 31 and a manifold 32. The cooling pipe 31 is rotatably connected to the end of the driving shaft 22 or the driven shaft 23 and communicates with the cooling channel 200. Figure 2 As shown, the manifold 32 is connected to the cooling pipe 31 to form a circulating water path between the cooling pipe 31 and the manifold 32 ; wherein, when the cooling mechanism 3 is working, the manifold 32 transports the coolant to each cooling pipe 31 and the cooling channel 200 .
[0040] When the base material transmission device for high-energy electron beam irradiation of the above technical solution is working, the conveying mechanism 2 drives the driving shaft 22 to rotate through the motor 21, and the driving shaft 22 then drives the conveyor belt 24 and the driven shaft to rotate, so as to realize the transportation of the culture material, and cooperate with the high-energy electron beam irradiation device above the conveyor belt 24 to sterilize the culture material. At the same time, the cooling mechanism 3 conveys the coolant to each cooling tube 31 and the cooling channel 200 through the manifold 32 to reduce the temperature of the driving shaft 22 and the driven shaft 23. Since the conveyor belt 24 is in contact with the outer surface of the driving shaft 22 and the driven shaft 23, according to the principle of heat conduction, the temperature of the conveyor belt 24 can be reduced to achieve the cooling effect. Compared with the traditional air cooling method, the cooling method of the base material transmission device does not have the problem of airflow blowing away the culture material. At the same time, the cooling efficiency is less affected by the ambient temperature, which can improve the efficiency and stability of the cooling conveyor belt 24, and is conducive to extending the service life of the conveying mechanism 2.
[0041] For example, Figure 3 As shown, the driving shaft 22 and the driven shaft 23 are provided with rollers in the middle. The rollers are made of metal material with high heat conduction efficiency and are used for transmission and contacting the conveyor belt 24.
[0042] In order to facilitate the timely discharge of the coolant from the cooling channel 200 when not in operation, refer to Figure 3 As shown, one end of the cooling pipe 31 is rotatably connected to the end of the driving shaft 22 or the driven shaft 23 and is communicated with the cooling channel 200, and the other end smoothly extends downward and is connected to the manifold 32. When the supply of coolant stops, the coolant inside the cooling channel 200 can automatically flow back to the manifold 32 by its own weight without the need to use conventional technical means such as adding a drain port to the cooling channel 200 or the cooling pipe 31, thereby having the advantages of simplified structure and easy use.
[0043] The manifold 32 is connected to the cooling pipe 31 to form a circulating water path between the cooling pipe 31 and the manifold 32. Figure 2 As shown, there are four cooling pipes 31, which are rotatably connected to the ends of the driving shaft 22 and the driven shaft 23 respectively. There are two conduits 32, which are connected to the cooling pipes 31 at both ends of the driving shaft 22 and the driven shaft 23 respectively, thus forming an annular circulating water circuit.
[0044] Exemplarily, one of the manifolds 32 inputs the coolant through a pipeline, and the other return pipe is used to output the coolant.
[0045] In one embodiment of the above-mentioned cooling pipe 31 being rotatably connected to the end of the driving shaft 22 or the driven shaft 23, see Figure 3As shown, one end of the cooling pipe 31 is rotatably sleeved in the cooling channel 200, and a sealing structure is provided between the driving shaft 22 and the driven shaft 23. In this way, when the driving shaft 22 and the driven shaft 23 rotate, the cooling pipe 31 is fixed relative to the frame 1, and the cooling pipe 31 will not interfere with the rotation of the driving shaft 22 and the driven shaft 23.
[0046] In one embodiment in which the cooling tube 31 is rotationally connected to the end of the driving shaft 22 or the driven shaft 23, the cooling tube 31 is connected to the end of the driving shaft 22 and the driven shaft 23 via a rotating joint, which neither interferes with the rotation of the driving shaft 22 and the driven shaft 23 nor allows the cooling liquid to be transported into the cooling channel 200.
[0047] In order to further improve the cooling effect, the conveying mechanism 2 includes an intermediate shaft 25 connected to the frame 1. Figure 1 As shown, the intermediate shaft 25 is located between the driving shaft 22 and the driven shaft 23, and its outer surface is in contact with the conveyor belt 24. A cooling channel 200 connected to the cooling pipe 31 is provided inside the intermediate shaft 25, so that the middle area of the conveyor belt 24 can be cooled by the intermediate shaft 25, thereby improving the cooling efficiency of the conveyor belt 24.
[0048] In order to prevent the base material from being scattered from the conveyor belt 24, refer to Figure 1 and Figure 3 As shown, the base material transmission device further includes a material blocking plate 11 , which is disposed on both sides of the conveyor belt 24 and is higher than the conveyor belt 24 .
[0049] Exemplarily, the baffle plate 11 is fixed on the frame 1 .
[0050] In order to ensure that the base material is conveyed on the conveyor belt 24 at a preset thickness, refer to Figure 1 and Figure 3 As shown, the base material transmission device also includes a scraper plate 12, and the two ends of the scraper plate 12 are respectively arranged on the baffle plates 11 on both sides of the conveyor belt 24, and a gap is formed between the conveyor belt 24. The gap is the same as the preset thickness of the culture medium during irradiation, which is beneficial to maintain the conveying thickness of the base material and ensure the sterilization effect of the base material.
[0051] For continuous delivery, see Figure 4 As shown, Figure 4 This is a three-dimensional diagram of the base material transmission device in the embodiment in which the front and rear end conveyor lines are arranged. The base material transmission device also includes a front end conveyor line 4 located at the front end of the conveying mechanism 2 and a rear end conveyor line 5 located at the rear end of the conveying mechanism 2. The front and rear end conveyor lines can use the existing conveyor belt 24, and are respectively used to transport and receive the culture material to the conveying mechanism 2.
[0052] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
