Description

Technical Field

[0001] The utility model relates to the technical field of sterilization, in particular to a sterilization system and a pretreatment chamber thereof. Background Art

[0002] Ethylene oxide sterilization is a chemical sterilization method that achieves the purpose of sterilization through the reaction of ethylene oxide gas with microorganisms in the items. Before the samples are placed in the sterilizer, they need to be pretreated. Different samples require different pretreatment times. Therefore, when processing different samples, the door of the pretreatment room needs to be opened from time to time. The temperature and humidity in the room are easily affected by the external environment, resulting in a decrease in temperature and humidity. Usually, a 2-fold compensation method is used to solve this problem, which results in a waste of energy and equipment utilization. Moreover, for the pretreatment of temperature-sensitive samples, the pretreatment time cannot be excessively extended, which requires the stability of the temperature and humidity control of the pretreatment process.

[0022] like Figure 1 As shown, the pretreatment chamber 100 is connected to the sterilization cabinet 200, so that the sample is pretreated in the pretreatment chamber 100 and then enters the sterilization cabinet 200 for sterilization. It should be noted that a transmission module can be provided between the pretreatment chamber 100 and the sterilization cabinet 200, so that the sample is processed in the pretreatment chamber 100, passes through the transmission module, and connects with the transmission line in the sterilization cabinet 200, and is automatically transferred to the transmission line in the sterilization cabinet 200 for sterilization. In this embodiment, the sample is the product to be sterilized.

[0023] Please refer to Figure 1-Figure 3The pretreatment chamber 100 includes a housing 110, a transmission line 120, an air conditioning unit 130, a return air duct assembly 140, a supply air duct assembly 150, a support assembly, a control device (not shown), a temperature sensor 160, a humidity sensor 170, a heating device, and a humidifier. The housing 110 has a cavity 111 and two opposing doors 112, which communicate with the cavity 111. The doors 112 serve as a feed door and a discharge door, respectively. The transmission line 120 is located within the cavity 111, allowing samples to enter through one door 112 and be placed on the transmission line 120 for pretreatment. After pretreatment, the samples enter the sterilizer 200 through the other door 112.

[0024] Among them, the shell 110 may include a frame and a panel, and the panel is arranged on the frame to form the shell 110. The shape of the shell 110 can be a rectangular parallelepiped or a cube. In addition, the frame can be made of galvanized square tubes welded in sequence, and the panel can be a double-sided color steel polyurethane sandwich panel. The door 112 is arranged on the panel on the side of the shell 110, and the door 112 can be an insulated rolling shutter door, so that it can play the role of high temperature resistance, high humidity resistance, and good sealing. The transmission line 120 is arranged in the cavity 111, and the sample is placed on the transmission line 120 for pretreatment. In one embodiment, the transmission line 120 is also electrically connected to the control device, and the control device starts the transmission line 120 after the sample is placed on the transmission line 120. The pretreatment chamber may also include a transport cart 300, which transfers samples to the transmission line 120, thereby enabling automatic control of the transmission line. Specifically, the transport cart 300 may be electrically connected to a control device, as may the doors 112. When the transport cart 300 transports the sample to one of the doors 112 (the feed door), a distance sensor may be positioned near the door 112 to detect the distance between the transport cart 300 and the door 112. When this distance reaches a preset value, the control device activates the opening of the door 112, causing the transport cart 300 to dock with the transmission line 120 and transfer the sample to the transmission line 120. When the sample reaches the other door 112 (the discharge door), a distance sensor may be positioned on the transmission line 120 to detect the distance between the sample and the other door. When the preset distance is reached, the control device controls the opening of the other door 112, allowing the sample to enter the sterilization chamber 200. The transmission line 120 may be a double-lane, fully automatic conveyor chain machine.

[0025] The support assembly is arranged on the top of the shell 110, and the air conditioning box 130, the return air duct assembly 140 and the supply air duct assembly 150 are all arranged on the support assembly and located between the support assembly and the top of the shell 110, that is, the air conditioning box 130, the return air duct assembly 140 and the supply air duct assembly 150 are all located outside the shell. The heating device and the humidifying device are respectively connected to the air conditioning box 130. The heating device is used to heat the air, so that the heated air enters the cavity through the air conditioning box 130 for circulation to change the temperature in the cavity. The humidifying device is used to generate evaporated water vapor, which enters the cavity through the air conditioning box for circulation to change the humidity in the cavity. The air conditioning box 130, the heating device, the humidifying device and most of the return air duct assembly and the supply air duct assembly are all located outside the shell, so as to reduce the impact of these components on the temperature and humidity in the cavity when they are working, and ensure the stability of the temperature and humidity in the cavity. Among them, the heating device can be a heating tube.

[0026] One end of the return air duct assembly 140 is connected to the air inlet of the air conditioning box 130, and the other end of the return air duct assembly 140 extends through the top of the shell 110 to the bottom of the cavity. One end of the supply air duct assembly 150 is connected to the air outlet of the air conditioning box 130, and the other end of the supply air duct assembly 150 extends through the top of the shell 110 to the top of the cavity 111. In other words, the other end of the return air duct assembly 140 extends to the bottom area of ​​the cavity. During circulation, air enters the return air duct assembly 140 from the bottom of the cavity, and the other end of the supply air duct assembly 150 extends to the top area of ​​the cavity. Thus, air enters the cavity 111 from the top of the cavity, forming a top-input and bottom-return circulation method. This increases the circulation area, ensures uniform temperature and humidity throughout the cavity 111, and further improves the stability of temperature and humidity in the pretreatment room. The return air duct assembly and the supply air duct assembly can be made of galvanized iron.

[0027] The temperature sensor 160, the humidity sensor 170, the air conditioning box 130, the heating device and the humidifying device are respectively connected to the control device. The temperature sensor and the humidity sensor respectively send the detected temperature and humidity values ​​in the cavity to the control device, and the control device controls the switch of the heating device and / or the humidifying device. Among them, the temperature sensor 160 and the humidity sensor 170 are arranged in the cavity 111 and are used to detect the temperature and humidity in the cavity. Specifically, when the sample is pre-processed, the temperature sensor 160 and the humidity sensor 170 send the detected temperature and humidity values ​​to the control device in real time. The control device receives the sent temperature and humidity values. If any of the values ​​is not within the preset range, the control device controls the switch of the heating device and / or the humidifying device. If the temperature value is lower than the minimum value of the preset range, the control device controls the heating device to turn on, and the heating device transmits hot air to the air conditioning box, which blows the hot air into the cavity through the air supply duct assembly. At the same time, the air in the cavity returns to the air conditioning box through the return air duct assembly, forming a large cycle to increase the temperature in the cavity; on the contrary, if the temperature value is higher than the maximum value of the preset range, the control device controls the heating device to stop working. Whether the humidifying device is turned on is the same as the heating device. If the humidity value is lower than the minimum value of the preset range, the control device controls the humidifying device to turn on, and the humidifying device transmits water vapor to the air conditioning box, which blows water vapor into the cavity through the air supply duct assembly. At the same time, the air in the cavity returns to the air conditioning box through the return air duct assembly, forming a large cycle to increase the humidity in the cavity; on the contrary, if the humidity value is higher than the maximum value of the preset range, the control device controls the humidifying device to stop working.

[0028] The above-mentioned pretreatment chamber includes a shell 110, a transmission line 120, an air conditioning box 130, a return air duct assembly 140, an air supply duct assembly 150, a support assembly, a control device, a temperature sensor 160, a humidity sensor 170, a heating device and a humidifying device. The shell 110 has a cavity and two oppositely arranged doors. The transmission line 120 is arranged in the cavity, so that the sample can enter the cavity from one door, be placed on the transmission line 120 for pretreatment, and enter the sterilization cabinet through the other door after the pretreatment is completed; the support assembly is arranged on the top of the shell 110, and the air conditioning box 130, the return air duct assembly 140 and the air supply duct assembly 150 are all arranged on the support assembly, and Located between the support assembly and the top of the shell 110, one end of the return air duct assembly 140 is connected to the air inlet of the air-conditioning box 130, and the other end of the return air duct assembly 140 extends to the bottom of the cavity through the top of the shell 110. One end of the supply air duct assembly 150 is connected to the air outlet of the air-conditioning box 130, and the other end of the supply air duct assembly 150 extends to the top of the cavity through the top of the shell 110, thereby forming a top-supply and bottom-return wind flow, increasing the area of ​​wind flow, and ensuring the stability of the entire pretreatment room temperature and humidity. The heating device, humidifying device, air-conditioning box 130, and air duct assembly are all located outside the shell 110, thereby reducing the impact on the temperature and humidity in the cavity. In addition, the temperature sensor 160, humidity sensor 170, air conditioning box 130, heating device and humidifying device are respectively connected to the control device. The temperature sensor 160 and humidity sensor 170 send the detected temperature value and humidity value to the control device. The control device controls the switch of the heating device and / or humidifying device according to the received temperature value and humidity value, thereby further ensuring the stability of the pretreatment room temperature and humidity.

[0029] In one embodiment, the support assembly includes multiple parallel, spaced-apart square tubes 180. It should be noted that, due to the limited support force of the panel, placing the air conditioning unit directly on top would affect the stability of the pretreatment chamber structure. Therefore, the support assembly is provided to support the panel at the top of the housing, which is located below the support assembly. In this embodiment, the support assembly includes multiple parallel, spaced-apart square tubes, so that the panel at the top of the housing is located below the multiple square tubes. A space is reserved between the square tubes and the top of the housing to facilitate the placement of the supply duct assembly 150 and the return duct assembly 140 within this space. Furthermore, the support assembly may also include a support platform 190. The support platform 190 is attached to the square tubes 180 and can be attached to a single square tube by welding or other means, or it can be arranged across multiple square tubes. The air conditioning unit 130 is mounted on the support platform 190. The placement of the support platform 190 further reduces pressure on the top of the housing and separates the air conditioning unit 130 from the duct assembly, resulting in a more compact structure and easier maintenance. It should be noted that because multiple square tubes 180 are spaced apart, the return and supply duct assemblies can pass through the gaps between adjacent square tubes 180 and extend into cavity 111. Specifically, through-holes are provided on the panel at the bottom of the housing, allowing the return and supply duct assemblies 140 and 150 to pass through corresponding through-holes and into the cavity. The support platform 190 may be a 4 mm patterned steel plate.

[0030] Furthermore, in one embodiment, the return air duct assembly 140 extends to the bottom of the cavity 111, and a return air window 141 is provided on the return air duct assembly. The return air window 141 is close to the bottom of the cavity, so that when the air conditioning box 130 is working, the air in the shell 110 can enter from the return air window 141 and circulate. It should be noted that in other embodiments, the opening at the other end of the return air duct assembly 140 can also be directly exposed to the bottom area of ​​the cavity 111. The provision of the return air window 141 can prevent impurities in the cavity 111 from entering the air duct and affecting the life and operation of the air conditioning box 130. Among them, the return air window 141 can be an adjustable shutter, and its size can be 400mm*250mm, and the size can be adjusted according to actual needs. Further, as Figure 2 As shown, the return air duct assembly 140 includes a main return air duct 142 and a branch return air duct 143. The main return air duct 142 is connected to the air conditioning box 130, and the branch return air duct 143 is connected to the main return air duct 142. The branch return air duct 143 extends to the bottom of the cavity 111, and the return air window 141 is opened on the branch return air duct 143. The number of branch return air ducts 143 can be multiple, and each branch return air duct 143 is connected to the main return air duct 142, and each branch return air duct 143 is connected to each other. With this arrangement, when the air conditioning box is in operation, the entire circulation is made more uniform, and the temperature and humidity distribution in the cavity 111 is more uniform.

[0031] In addition, in one embodiment, the air supply duct assembly 150 includes a plurality of air vents 152 and an air supply duct 151, the air vents 152 are all connected to the air supply duct, one end of the air supply duct 151 is connected to the air conditioning box 130, and the other end of the air supply duct 151 is connected to the air vents 152, the number of the air vents 152 is multiple, and the multiple air vents 152 are arranged at intervals. Preferably, the multiple air vents 152 are evenly distributed so that the wind can be evenly blown into the cavity 111. In this embodiment, the air vents 152 are swirl air vents, and the material used can be aluminum alloy. Specifically, a through hole is opened on the top of the shell 111, and the air vents 152 are stuck in the through hole or pass through the through hole, so that the air outlet of the air vents 152 is exposed in the cavity 111.

[0032] Please refer to Figure 2 In one embodiment, both the temperature sensor 160 and the humidity sensor 170 are located on the transmission line 120. Furthermore, the temperature sensor 160 and the humidity sensor 170 are located between the first and second trays on the transmission line 120. The first and second trays are the two trays closest to the door 112. By locating the temperature sensor 160 and the humidity sensor 170 between the first and second trays on the transmission line 120, the temperature sensor 160 and the humidity sensor 170 are located near the door 112. Since the temperature and humidity within the cavity are most easily affected when the door 112 is opened, the temperature and humidity near the door are most likely to be affected and fluctuate. This avoids delays in processing due to changes in temperature and humidity, further ensuring the stability of the temperature and humidity within the cavity. Furthermore, the temperature sensor 160 and the humidity sensor 170 can be located near both doors 112.

[0033] Please refer to Figure 2In one embodiment, the pretreatment chamber further includes a wind speed sensor 153, which is disposed on the air supply duct assembly and electrically connected to the control device. Specifically, when the air supply duct assembly includes an air supply duct and multiple air outlets, the wind speed sensor 153 is disposed on the air supply duct 151. The wind speed sensor 153 is used to detect the air supply speed of the air supply duct 151 and transmit the air supply speed to the control device. The control device can then control the operating power of the air conditioning unit based on the air supply speed, thereby adjusting the air supply speed. For example, if the temperature within the cavity 111 needs to be increased, the heating device operates, diffusing hot air into the air conditioning unit. The hot air then diffuses out from the air supply duct 151 and air outlets 152 in turn. Initially, the temperature within the cavity is low, and the air conditioning unit 130 can supply air at a higher speed. When the temperature within the cavity is about to reach a preset temperature, the air supply speed can be reduced. Thus, by providing the wind speed sensor 153, the control device can monitor the air supply speed and, based on the temperature value transmitted by the temperature sensor, adjust the operating power of the air conditioning unit. Similarly, the humidity is controlled in the same manner as the temperature, which will not be described in detail here.

[0034] In this embodiment, the control device may be a PLC. As can be seen above, the control device can control the operation of the heating device, humidifying device, and air conditioning box 130 based on information transmitted by the temperature sensor 160, humidity sensor 170, and wind speed sensor 153, thereby regulating the temperature and humidity within the pretreatment chamber in real time. Furthermore, the control device can automatically adjust the temperature and humidity within the cavity 111 for different samples according to a pre-set program. Specifically, the order of pretreatment samples is pre-set, so the required temperature and humidity for each sample can also be known in advance. Taking the pretreatment of samples A and B as an example, when pretreatment of sample A is completed, the control device adjusts the temperature and humidity within the cavity to the temperature and humidity corresponding to sample A until pretreatment of sample A is complete. After pretreatment of sample A is completed, the control device automatically adjusts the temperature and humidity within the cavity to the temperature and humidity required for pretreatment of sample B. This allows the pretreatment chamber to pretreat a variety of samples, improving the efficiency of the pretreatment chamber and, therefore, improving work efficiency. It should be noted that the control device adjusts the temperature and humidity within the cavity according to the pretreatment temperature and humidity required for each sample as described above. If the pretreatment temperature required for sample A is lower than that required for sample B, the control device activates the heating device to transfer hot air into cavity 111 to increase the temperature. If the pretreatment temperature required for sample A is higher than that required for sample B, the control device deactivates the heating device. Humidity is regulated in the same manner as temperature and will not be further described here.
