After sterilization, the product is placed in the product packaging, and the product can be sold to consumers in a clean storage environment. Therefore, sterilizing the product packaging is a necessary step for the sale of the above-mentioned products, and a pressure cabin such as a sterilization cabin that requires a high-pressure medium inside will be used.

[0003] In the prior art, a sterilization cabin is mainly used to sterilize product packaging transported inside by high-temperature and high-pressure medium. It is mainly composed of an outer wall plate and an inner partition plate. The inner partition plate can divide the space in the cabin to form the required sterilization channel. The outer wall plate is sealingly connected to the inner partition plate to ensure that a high-temperature and high-pressure sterilization environment can be formed inside the cabin. However, due to the high-pressure environment inside the cabin, the outer wall plate will be pushed outward under high pressure, which can cause the outer wall plate to deform outward. This can cause the sealing connection between the outer wall plate and the inner partition plate to be pulled, which can damage the sealing connection and cause the seal to fail. The high-temperature and high-pressure environment in the sterilization cabin can leak, which can cause energy loss and affect the sterilization effect. In addition, it can cause damage to the surrounding environment and workers due to the high safety risk. SUMMARY

DETAILED DESCRIPTION

[0041] In order for those skilled in the art to better understand the technical scheme of the utility model, the utility model will be further described in detail below in combination with specific embodiments.

[0042] Please refer to Figure 1 and Figure 2As shown, the embodiment of the present application provides a cabin body, which comprises a plate one 1 and a plate two 2.

[0043] The cabin body is mainly composed of a plurality of plate ones 1 and a plurality of plate twos 2, which are used to connect to form an inner space of the cabin that can be filled with pressure medium such as steam, water, etc. or used for storage. The inner space of the cabin can be the entire space in the cabin body, or a part of the space in the cabin body, which is not limited. For example, when the inner space of the cabin is the entire space in the cabin body, the plate one 1 and the plate two 2 are the outer wall plates of the cabin body. When the inner space of the cabin is a part of the space in the cabin body, the plate one 1 is a partition plate arranged in the cabin body, and the plate two 2 can be an outer wall plate or an inner partition plate. The inner space of the cabin formed by the plate one 1 and the plate two 2 can be filled with pressure medium. Under the action of the pressure medium, the plate one 1 and / or the plate two 2 bear the pressure brought by the pressure medium.

[0044] In some application scenarios, the cabin body is preferably a sterilization cabin. The sterilization cabin needs to be filled with high-temperature and high-pressure steam or water. The entering product to be disinfected is disinfected by such pressure medium, such as Figure 2 As shown, in the sterilization cabin, the plate one 1 is an inner partition plate for separating the internal space to form a sterilization channel, and the plate two 2 is an outer wall plate and is the main pressure-bearing object. In addition, the cabin body can also be other cabins that need to bear a large pressure in the interior, which is not limited.

[0045] In order to mainly avoid the problem that the plate two 2 is pulled at the sealing connection 3 with the plate one 1 under pressure, please refer to Figure 3 and Figure 4 As shown, in the embodiment of the present application, the edge of the plate one 1 is connected with a connecting member 4, the connecting member 4 has a connecting part 41 extending to the outside of the edge of the plate two 2, the edge of the plate two 2 has a folded edge 21, the folded edge 21 is connected with the connecting part 41 and connected with each other to form a reinforcing rib 5 with a sealing connection 3, a clamp 6 is clamped and connected on the outside of the reinforcing rib 5, and the clamp 6 is further provided with a blocking part 63 abutting against the bending part of the folded edge 21.

[0046] The connecting member 4 is arranged at the edge of the plate one 1, the edge refers to the end of one or more circumferential sides, and the plate one 1 is connected with the plate two 2 through the connecting member 4. The connecting part 41 of the connecting member 4 can be connected with the folded edge 21 of the plate two 2 and form a group of reinforcing ribs 5 through a sealing connection mode such as welding. The reinforcing ribs 5 have a sealing connection 3. In order to avoid the sealing connection 3 from being pulled and losing sealing effect, the clamps 6 are used to clamp the reinforcing ribs 5, and the abutting part of the clamp 6 abuts at the bending part of the folded edge 21, so as to prevent the plate two 2 from pulling the reinforcing ribs 5 including the folded edge when being pressed, that is, the bending moment generated when the plate two 2 is deformed can resist the influence on the sealing connection 3, and the stability and reliability of the sealing connection 3 are effectively ensured. The folded edge formed by the bending of the periphery of the plate two 2 can transmit the force outward, and the plate one 1 is sealingly welded to transmit the force to the connecting member 4, and the connecting member 4 bears the force, and all the forces are basically borne by the connecting member 4, so that the force borne by the plate one 1 and the plate two 2 is reduced, and the structure design is more reasonable and effective.

[0047] Through the above technical solution, the connecting member 4 connected with the plate one 1 can be connected with the folded edge 21 of the plate two 2 to form the reinforcing ribs 5 with the sealing connection 3. The reinforcing ribs 5 can resist the bending part of the folded edge 21 through the abutting part of the clamp 6, so as to prevent the plate two 2 from pulling the sealing connection 3 when being pressed and deformed, effectively reduce the transmission of the bending stress to the reinforcing ribs 5, and realize the protection of the sealing connection 3, thereby ensuring the sealing property.

[0048] In some embodiments, the connecting member 4 can be fixedly connected with the plate one 1 through fasteners, or can be connected in a plug-in manner according to the plate structure of the plate two 2, and is not limited.

[0049] In the embodiment in which the cabin body is a sterilization cabin, the plate one 1 is an inner partition plate, and a plurality of plate one 1s are arranged in parallel and staggered to form an S-shaped sterilization channel in the cabin, and a conveying mechanism is arranged in the sterilization channel. The products or packages to be sterilized are conveyed and sterilized in the sterilization channel through the conveying mechanism. Therefore, in such a cabin structure, the plate one 1 is a composite plate and can include multiple layers. Correspondingly, the connecting member 4 can be connected with the plate one 1 in a plug-in manner.

[0050] On this basis, please continue to refer to Figures 5-8 In an embodiment, the plate one 1 is a composite plate and includes a main rib 15 and a skin layer 11. The main rib 15 is arranged in parallel and spaced apart with a plurality of main ribs 15. The skin layer 11 is attached to the outer side of the main rib 15. The connecting member 4 is connected to the end of the main rib 15.

[0051] The plate one 1 has two skin layers 11 and the skin layers 11 are as the surface layers of the plate one 1, the inner side of which is provided with a framework mainly composed of main ribs 15, the main ribs 15 can support the skin layers 11, and the connecting member 4 is connected with the end of the main ribs 15, thereby forming a stable and reliable connecting structure between the connecting member 4 and the plate one 1. In the specific implementation process, the plurality of filling cavities formed by the longitudinal ribs 16 and the main ribs 15 between the two skin layers 11 can be filled with thermal insulation materials, thereby realizing the thermal insulation of each sub-channel of the sterilization channel of the sterilization cabin.

[0052] In order to further improve the sealing and reliability of the space in the cabin formed by the connection of the plate one 1 and the plate two 2, further, please continue to refer to Figure 3 and Figure 4 , the skin layer 11 extends outwardly to the extending direction of the main rib 15 to form an extension part 12, the extension part 12 extends to the connection part 41 and the folded edge 21, thereby the folded edge 21, the extension part 12 and the connection part 41 are attached to form a three-layer structure, the folded edge 21, the extension part 12 and the connection part 41 are connected to form a reinforcing rib 5, and the reinforcing rib 5 is formed with a sealed connection part 3 by welding or the like.

[0053] In this way, the skin layer 11 participates in the connection to form the reinforcing rib 5 connected and welded by the folded edge 21, the extension part 12 and the connection part 41, which can further improve the sealing between the plate one 1 and the plate two 2, and make the connecting structure more stable and reliable.

[0054] Further, in combination with Figure 3 and Figure 13 , the end of the main rib 15 is provided with a cutout 17 on both sides, the connecting member 4 is provided with a plug-in part 42 plugged into the cutout 17, and the skin layer 11 covers the plug-in part 42.

[0055] In this way, the connecting member 4 can be plugged into the cutout 17 of the main rib 15 through the plug-in part 42, and the connecting member 4 is welded to the cutout 17 of the main rib 15 through the plug-in part 42 to be connected, thereby forming a relatively fixed connecting structure, so that the plug-in part 42 of the main rib 15 and the connecting member 4 is not easy to dislocate.

[0056] Specifically, in combination with Figure 3 , Figure 8 and Figure 14As shown, the connecting member 4 adopts an I-shaped member as the connecting member 4, two flanges on one side of the I-shaped member as the insertion part 42 and embedded in the matching cutout 17, and two flanges on the other side of the I-shaped member as the connecting part 41, which can make the connecting member 4 have better structural stability and supportability, and the connection is more stable. In addition to the I-shaped member, the connecting member 4 can also be a channel steel. Moreover, the connecting member 4 also serves as the connecting member of the outer wall plate of the sterilization cabin, which can be connected with a whole plate two 2 as the outer wall plate or a plate one 1 composed of multiple sub-plates each provided with a folded edge 21, and after connection, a longitudinal reinforcing rib 5 can be formed, and then clamped and limited by the clamp 6. Please combine Figure 12 As shown, when the plate one 1 and the plate two 2 are connected head to tail as two vertical edges of the cabin inner space, that is, both as outer wall plates or both as inner partitions, the connecting member 4 is an L-shaped member, one side of the L-shaped member as the connecting part 41 is connected and welded with the folded edge of the plate two 2 to form the reinforcing rib 5, and the other side of the L-shaped member as the limiting edge 62 is fixed by the clamp 6. The clamp 6 can be a U-shaped structure or a rod-shaped structure with a clamping groove, and is not limited.

[0057] On this basis, the clamp 6 is arranged at intervals along the length direction of the reinforcing rib 5. By multiple clamps 6, clamping, limiting and installation can be performed from multiple points, which is convenient, efficient, easy to maintain, and can be fixed on the reinforcing rib 5 by welding, which has good connection stability.

[0058] In another embodiment, in combination Figure 11 As shown, the plate one 1 can adopt a plate structure without a skin layer 11, or has a skin layer 11 which does not participate in connection. In such a connection mode, the connecting member 4 and the plate one 1 can be connected in a fixed connection mode, such as clamping or connecting by fasteners, so that the connecting member 4 and the plate one 1 have reliable connection, and then the plate one 1 forms the reinforcing rib 5 with the folded edge 21 through the connecting part 41 of the connecting member 4, and the clamp 6 can also realize the protection of the sealed connection 3.

[0059] In one embodiment of the clamp 6, in combination Figure 3 and Figure 4 As shown, the clamp 6 includes a main plate bent into a U shape, and a reinforcing plate 61 is further connected on the outside of the main plate along the cross-sectional direction of the U-shaped main body.

[0060] The main plate is in U-shaped structure, which can facilitate the reinforcement 5 to be clamped therein, and the resisting part is on one side of the open end of the main plate, which is in abutment with the bending part of the bent edge, so as to protect the sealing connection 3, and the clamping structure is stable through the reinforcing plate 61 integrated with the main plate, and the resistance performance is stronger. In addition, the main plate can be provided with the resisting edge 62 formed by being integrated with the main plate and being folded, and the reinforcing plate 61 is in abutment with or integrated with the resisting edge 62, so that the sealing connection 3 can be better avoided from being pulled. Of course, the resisting edge 62 can not be provided, and more clamps 6 can also play a reliable resisting role by being provided.

[0061] In another embodiment of the clamp 6, the clamp 6 comprises a clamping piece and a reinforcing plate, the clamping piece is in U-shaped structure, and the reinforcing plate is provided with a clamping groove matched with the clamping piece.

[0062] In this embodiment, the clamp 6 is in split structure, the clamping piece and the reinforcing plate can be separated, and the reinforcing plate is clamped and connected with the clamping piece through the clamping groove, so that replacement and assembly are more convenient.

[0063] The clamp 6 of the above two embodiments can replace the traditional bolt connection to organically connect the two skin layers 11 of the partition plate 1 and the I-beam in force, so that the folded edges 21 of the two side outer wall plates 2 can always maintain a good force state, and the folded edges 21 of the two side outer wall plates and the sealing weld of the partition plate 1 are in a non-force state, so that the forces of the outer wall plate, the partition plate 1 and the I-beam are balanced and offset, and the construction is easy.

[0064] Please refer to Figure 8 and Figure 9 In the embodiment of the present application, the skin layer 11 can be further provided with an arc-shaped concave surface 13, and the arc-shaped concave surfaces 13 of the two skin layers 11 of the plate 1 are provided with a supporting piece.

[0065] The arc-shaped concave surface 13 can improve the bending resistance of the plate 1 in the plate surface direction, reduce the thickness of the used plate material, and improve the compression resistance of the plate 1 in the direction perpendicular to the plate surface through the abutment of the supporting pieces of the two skin layers 11, so as to realize the improvement of the structural reliability and stability of the plate 1 from different force directions.

[0066] Preferably, the support member comprises a support disc 14 which covers the back side of the arc-shaped concave surface 13 and abuts against the support disc 14 of the opposite arc-shaped concave surface 13. The support disc 14 is capable of being matched to cover the arc-shaped concave surface 13, and the inner diameter of the support disc 14 is smaller than the diameter of the arc-shaped concave surface 13. The skin layer 11 is capable of decompressing the pressure through the arc-shaped concave surface 13, so as to realize thinning of the wall thickness while improving the pressure bearing capacity, and the support member is also capable of resisting the pressure from the vertical plate surface, thereby realizing the structural performance of the plate 1 in terms of compression resistance and bending resistance.

[0067] Please refer to Figures 1-13 The embodiments of the present application also provide a sterilization cabin, which comprises the cabin body according to any one of the technical solutions above, and the plate 1 and the plate 2 are arranged in an upper-lower staggered manner in the cabin body to form a sterilization channel of a curved path, and the sterilization channel is provided with a conveying mechanism for conveying products to be sterilized arranged according to the curved path.

[0068] In the specific implementation process, please refer to Figure 10 Since the sterilization channel in the sterilization cabin is provided with the conveying mechanism, in order to facilitate the installation of the conveying mechanism, a support part 7 for bearing the conveying mechanism is connected to the connecting member 4 in the extension direction of the connecting member 4, and the support part 7 comprises an annular part 71 and an abutting part 72 extending in the diameter direction of the annular part 71, and the abutting part 72 is connected to the connecting member 4. In this way, the support part can facilitate the installation of the main mounting components such as the rotating shaft of the conveying mechanism in the annular part 71, and the support part is connected to the connecting member 4 through the abutting part 72, so that the conveying mechanism can be supported by the connecting member 4.

[0069] Specifically, the abutting part 72 of the support part 7 adopts a strip-shaped plate structure matched with the groove of the connecting member 4 of the I-shaped member, and the outer side surface of the annular part 71 of the support part 7 is in limiting relationship with the connecting member 4 in the length direction of the connecting member 4, so as to be capable of stable support; the support part 7 can be made of a flange plate, and the abutting part 72 is welded to the upper and lower sides of the flange plate, and transverse connecting ears 74 are arranged on the left and right sides of the support part 7, so as to be connected to the transverse rods on the two sides through the transverse connecting ears 74; of course, a fixed cover plate 73 for preventing the support part 7 from being separated from the connecting member 4 can be arranged on the outer side of the support part 7, and the fixed cover plate 73 is fixedly connected to the connecting member 4.

[0070] In addition, the parts of the cabin body that contact water are made of stainless steel; the clamps and reinforcing plates are made of carbon steel, and plate one and plate two need to be fully welded, and the carbon steel and stainless steel do not need to be fully welded; the cabin body can also be used as a liquid storage container at a height greater than that of a common spherical water tank. For example, a cabin body greater than ten meters high, and the cabin body is more convenient to construct than the conventional spherical water tank sealing welding scheme inside, which is mainly welded on the outside, while greatly reducing the sealing weld.

[0071] To more fully illustrate the sterilization principle and related mechanisms of the sterilization cabin of the embodiments of the present application, please refer to Figures 15-17 In one embodiment, the sterilization cabin includes a cabin body structure, an energy-saving water circulation system, a steam circulation system, a detection and control system, and the like. The sterilization cabin uses hydrostatic pressure sterilization to sterilize and disinfect. The principle is to use high-temperature and high-pressure steam in a sealed environment to sterilize and disinfect the items. Specifically, the items to be sterilized are placed in a sealed sterilization cabin, and then the steam pressure in the sterilization cabin is increased to sterilize and disinfect the items at high temperature and high pressure. In this process, the high-temperature and high-pressure steam can destroy the proteins, nucleic acids, cell walls, and cell membranes of microorganisms, causing the microorganisms to die and thus achieving sterilization. As shown in Figures 15-17The conveying mechanism 400 of the sterilization cabin shown is a circulating conveying line, and part of the conveying mechanism 400 is arranged in an S-shaped sterilization channel. The circulating conveying of the conveying mechanism 400 can realize continuous sterilization processing. Specifically, the sterilization channel includes a preheating section 130, a sterilization section 140, and a cooling section 150 arranged along the conveying direction. The lower parts of the preheating section 130 and the cooling section 150 are respectively provided with at least one U-shaped communication section. The U-shaped communication sections at the lower parts of the preheating section 130 and the cooling section 150 are filled with liquid to form a water seal structure. In this way, the liquid can form a seal and allow the sterilization product to pass through. By pressurizing the side of the U-shaped communication section close to the sterilization section 140, the liquid moves in the U-shaped communication section due to the pressure difference and forms a height difference on both sides of the U-shaped communication section. Thus, on the basis of maintaining the sealed state, multiple relatively independent and pressure-differential sealed chambers can be realized in the channel of the S-shaped path. The sterilization section 140 forms a sealed chamber isolated from the outside due to the water seal effect. The pressure of each sealed chamber in the direction from the preheating section 130 to the sterilization section 140 gradually increases, while the pressure of each sealed chamber in the direction from the sterilization section 140 to the cooling section 150 gradually decreases. Thus, the sterilization section 140 has the highest pressure. By controlling the height difference of the liquid in the U-shaped communication sections of the preheating section 130 and the cooling section 150 and the number of U-shaped communication sections in the preheating section 130 and the cooling section 150, the required high-pressure environment in the sterilization section 140 is realized by gradually increasing the pressure. Moreover, the overall volume and height of the sterilization cabin will not be too large, the compactness is good, the construction cost is low, and the safety and reliability are high. In addition, the sterilization cabin with this structure can gradually preheat and cool the sterilization product in the preheating section 130 and the cooling section 150, ensuring the integrity of the product, strengthening the cooling and heating effect, and facilitating the maximum utilization of heat. The sterilization product is heated in the preheating section 130 and cooled in the cooling section 150. The heat lost by the sterilization product in the cooling section 150 can be recycled to preheat the sterilization product in the preheating section 130, thereby realizing the recycling of heat.

[0072] In a specific embodiment, the preheating section 130 and the cooling section 150 are respectively provided with two U-shaped communication sections. By pressurizing, a 5.5-meter (adjustable according to the process) water column height difference is established in each U-shaped communication section. Thus, the absolute pressure in the sterilization section 140 is equal to the atmospheric pressure plus the pressure of two 5.5-meter water columns, that is, 207.88 KPa. In a sealed environment, the greater the pressure, the higher the temperature that the steam can reach. At this time, the saturated steam pressure in the sterilization section 140 is 121 degrees Celsius. When the sterilization product passes through the sterilization section 140, the high-temperature and high-pressure saturated steam can destroy the proteins, nucleic acids, cell walls, and cell membranes of microorganisms, thereby causing the death of microorganisms.

[0073] Regarding the establishment of pressure difference and temperature, specifically, the preheating section 130 includes a first U-shaped communication section 131 and a second U-shaped communication section 132 arranged along the conveying direction of the conveying mechanism, the cooling section 150 also includes a fifth U-shaped communication section 151 and a sixth U-shaped communication section 152 arranged along the conveying direction of the conveying mechanism, and the sterilization section 140 can also include a third U-shaped communication section 141 and a fourth U-shaped communication section 142 arranged along the conveying direction of the conveying mechanism. First, an appropriate amount of liquid is injected into the first U-shaped communication section 131, the second U-shaped communication section 132, the fifth U-shaped communication section 151, and the sixth U-shaped communication section 152, respectively, to divide the equipment into a gas phase space A 160, a gas phase space B 170, and a gas phase space C 180. As shown in FIG. 8, when the sterilization cabin is in a non-working state, the gas phase space A 160, the gas phase space B 170, and the gas phase space C 180 are in a normal pressure state with the same pressure as the external environment, so that the liquid levels on both sides of the first U-shaped communication section 131, the second U-shaped communication section 132, the fifth U-shaped communication section 151, and the sixth U-shaped communication section 152 are in an isobaric state. As shown in FIG. 9, when the sterilization cabin is in a working state, gas is introduced into the gas phase space A 160, the gas phase space B 170, and the gas phase space C 180 to pressurize, saturated steam of 207.88 KPa is introduced into the gas phase space B 170 (which has a water supply system at the bottom), and steam of 153.94 KPa is introduced into the gas phase space A 160 and the gas phase space C 180. The liquid on both sides of the second U-shaped communication section 132 and the fifth U-shaped communication section 151 gradually establishes a liquid level difference of 5.5 meters, and the liquid on both sides of the first U-shaped communication section 131 and the sixth U-shaped communication section 152 also establishes a liquid level difference of 5.5 meters. After the pressure in the pressure monitoring gas phase space B 170 reaches 207.88 KPa, the liquid phase space at this time is as shown in FIG. 10. At this time, the pressure P1 of the gas phase space A 160 and the gas phase space C 180 is P1 = P0 + 5.5 meters of water pressure = 100 + 53.94 = 153.94 KPa, and the pressure P2 of the gas phase space B 170 is P2 = P1 + 5.5 meters of water pressure = 153.94 + 53.94 = 207.88 KPa, where P0 is the atmospheric pressure and is 100 KPa. In this way, high temperature and high pressure can be established in the sterilization section 140 by gradually increasing the pressure. Figure 16 Figure 17 Figure 17

[0074] By the above-mentioned pressurization method, the steam in the gas phase space B 170 can obtain a higher temperature for sterilization, achieving high-temperature sterilization. Such a cabin structure can also be used for pasteurization by controlling the temperature to a temperature range of 62-65°C or 75-90°C without pressurization, so that pasteurization can also be achieved, and the application range is wider.

[0075] ​​​In order to reduce the production energy consumption and improve the heat utilization rate, a circulating system is established between the preheating section 130 and the cooling section 150, and further, combined with Figures 17-19 As shown, a water pump is arranged at the left upper end of the first U-shaped communication section 131 and connected with the external heat exchange system, and the hot water is pumped into the sixth U-shaped communication section 152 through the water pump at the left lower end of the sixth U-shaped communication section 152 after heat exchange (the water temperature is lower than the normal temperature), and the material is cooled by the low-temperature liquid; a water pump is arranged at the right side of the sixth U-shaped communication section 152 and connected with the fifth U-shaped communication section 151, and the high-position liquid in the sixth U-shaped communication section 152 is pumped into the bottom of the fifth U-shaped communication section 151; at the same time, a water pump is arranged at the right side of the fifth U-shaped communication section 151 and connected with the second U-shaped communication section 132, and the liquid with higher temperature in the fifth U-shaped communication section 151 is pumped into the bottom of the second U-shaped communication section 132 to preheat the material; and a water pump is arranged at the left side of the second U-shaped communication section 132 and connected with the first U-shaped communication section 131, and the liquid in the second U-shaped communication section 132 is pumped into the bottom of the first U-shaped communication section 131. In this way, an energy-saving circulating system can be formed, and the liquid absorbing heat in the cooling section 150 is flowed to the preheating section 130 to preheat the material, thereby improving the heat utilization rate.

[0076] Since sterilization of some small packages or long strip packages may exist in some application scenarios, in order to be compatible and adaptive, combined with Figure 15 , Figure 20 and Figure 21 As shown, the carrier 190 arranged on the conveying mechanism 400 can be a box carrier, and the carrier 190 is rotationally connected with the chain of the conveying mechanism 400 through a rotating shaft to rotate freely, so that the carrier 190 can maintain a stable posture under the action of gravity for sterilization, that is, the opening of the carrier 190 is upward to stably store the material carrier. The conveying mechanism 400 can adopt two running modes, one is to stop the carrier 190 intermittently at the feeding station 300 and the discharging station 200 for feeding and discharging, and to keep the carrier 190 continuously and uninterruptedly running in the preheating section 130, the sterilization section 140 and the cooling section 150 for sterilization, and specifically, a retracting mechanism can be arranged at the feeding station 300 and the discharging station 200 respectively to link the intermittent motion and the continuous motion; the other mode is that the entire chain of the conveying mechanism 400 is in a continuously and uninterruptedly running state, and the carrier 190 in continuous movement is fed and discharged at the feeding station 300 and the discharging station 200, and specifically, a following type feeding and discharging mode can be adopted.

[0077] In the loading station 300, the loading conveyor is a conveyor belt arranged above the conveying path of the carriers 190. The materials are freely dropped into the carriers 190 with the opening facing upward at the end of the conveyor belt. In this way, the loading can be carried out while the carriers 190 maintain a continuous and uninterrupted state of movement in the loading station 300, which is simple in structure and easy to implement. Meanwhile, in order to facilitate the unloading of the sterilized articles, the unloading station 200 is combined with the loading station 300, as shown in Figure 20 and Figure 21 The unloading station 200 further comprises a turnover and unloading device 210. The turnover and unloading device 210 comprises a first moving mechanism 211, a second moving mechanism 212, a rotating mechanism 213, a connecting disc 214 and a chuck 215. The second moving mechanism 212 is arranged on the first moving mechanism 211 in a direction perpendicular to the conveying direction of the carriers 190. The rotating mechanism 213 is arranged on the second moving mechanism 212. The connecting disc 214 is connected to the output end of the rotating mechanism 213. The chuck 215 is arranged on the carrier 190. The chuck 215 is circumferentially provided with a limiting groove 217 which is engaged with or meshed with the shaft 216 to form a limiting fit in the circumferential direction. When the carrier 190 moves to the unloading station 200, the first moving mechanism 211 drives the second moving mechanism 212 to move synchronously with the carrier 190. In this process, the second moving mechanism 212 is extended and the shaft 216 on the connecting disc 214 is inserted into the limiting groove 217 of the chuck 215. Then, the rotating mechanism 213 drives the carrier 190 to rotate so as to rotate the carrier 190 to the opening facing downward to unload the materials. Then, the rotating mechanism 213 drives the carrier 190 to rotate back to the original position. The second moving mechanism 212 is reset to retreat so as to separate the connecting disc 214 from the chuck 215. The first moving mechanism 211 is reversely moved to reset to drive the next carrier 190 to unload. In this way, the articles in the carrier 190 can be turned over to unload, which is convenient and fast.

[0078] In order to facilitate production and transportation, the sterilization cabin can be divided into two or more modules. The sterilization cabin is divided into modules in the plane of the partition plate, as shown in Figure 1 and Figure 2As shown, a single module can include 5 partition plates 1 staggered, and a connecting partition plate 18 is arranged at both ends of the single module, the connecting partition plate 18 is parallel to the partition plate 1, the connecting partition plate 18 can adopt the same structure as the partition plate 1 or a different structure, and the connecting partition plate 18 can specifically include the main rib 15 and the skin layer 11, a plurality of main ribs 15 are arranged side by side and at intervals, the skin layer 11 covers the surface plane of the framework formed by the main ribs 15, the skin layer 11 is processed by sheet metal processing to have a convex structure, the connection of adjacent modules is achieved by splicing of the adjacent connecting partition plates 18, and the connecting partition plate 18 of the module at the end forms the outer wall surface of the end side of the sterilization cabin, and the cover member at the top end and the bottom end of the module end side is a half semicircle; when two modules are connected, the end sides of the two modules are aligned and the side wall plates and the cover members are welded, so that splicing connection can be achieved, which is more convenient and fast.

[0079] The single module occupies a smaller volume and has a lighter weight, is convenient for transportation, and is easy to assemble. Through the superposition of multiple modules, the working efficiency of the sterilization cabin formed by splicing of multiple modules and serving as a sterilization line can be improved.

[0080] On this basis, in combination with Figure 1 and Figure 2 As shown, in order to facilitate production and assembly, a plurality of oval convex structures 22 are continuously punched on the side wall plate 2 and the skin layer 11, the convex structures 22 can improve the compression and bending resistance, so that compared with the existing water tank structure in which each convex structure 22 is a plate and is welded to each other, the welding seams for splicing can be reduced, and the external welding and construction inspection are facilitated.

[0081] Through the modular design described above, the welding connection of the side of the connecting partition plate 18 and the welding between the side wall plates 2 can be performed when each module is connected to each other, so that the sealing welding seams of all modules can be welded outside the container, which is convenient for construction and inspection.

[0082] The sterilization cabin of the embodiment of the present application adopts the sterilization mode of hydrostatic pressure steam sterilization, which can be applied to various articles that need high temperature and high pressure treatment, such as high temperature and high humidity resistant articles, microbial cultures, liquids, medicines, etc. It has the following advantages:

[0083] 1. Good sterilization effect: can kill most microorganisms including spores.

[0084] 2. Wide application range: suitable for various types of articles, including liquids, porous articles, etc.

[0086] 4. The sterilization method can be various: the required conditions of the pasteurization can be achieved by controlling the temperature and without pressure.

[0087] The above is only the preferred embodiment of the present application, it should be pointed out that the above preferred embodiment should not be regarded as limiting the present application, the protection scope of the present application should be limited by the scope defined by the claims. For ordinary skilled in the art, without departing from the spirit and scope of the present application, can make a number of improvements and refinements, these improvements and refinements should also be regarded as the protection scope of the present application.
