Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0026] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0027] Please see Figure 1-2 This utility model provides a technical solution: a biosafety isolator waste recovery device, comprising:
[0028] The recycling tank 1 has a slag discharge port 3 at its bottom, and a sealing cap 4 is installed on the slag discharge port 3. The recycling tank 1 is provided with an air inlet 5 and an exhaust port 6, and the air inlet 5 extends to the bottom of the inner cavity of the recycling tank 1.
[0029] The conveying pipeline 2 connects to the waste inlet in the middle of the recycling tank 1 and the waste outlet of the isolator.
[0030] The air inlet 5 connects to an externally installed sterilizing steam generator, and the exhaust outlet 6 connects to an externally installed waste gas treatment mechanism. The sterilizing steam generator is existing technology; it heats a liquid at high temperature to evaporate it, forming high-temperature, high-pressure steam. This steam is then introduced into the recovery tank 1 through the air inlet 5 to sterilize the contaminants and air inside. The specific structure of the sterilizing steam generator will not be described in detail here. The waste gas treatment mechanism collects and treats the waste gas entering the recovery tank 1. Its specific structure will also not be described in detail here.
[0031] Several manual control valves 7 are arranged at intervals on the conveying pipeline 2 to control the flow speed of the waste in the conveying pipeline 2 and ensure that the waste enters the recycling tank 1 in a stable manner.
[0032] The conveying pipeline 2 connects to the branch pipeline 8, and a first detector 9 is installed on the branch pipeline 8. The first detector 9 detects bacteria and other contaminants in the contaminants in the conveying pipeline 2 in order to adjust the subsequent high-temperature steam sterilization time.
[0033] A branch pipe extends from the recovery tank 1, and a second detector 10 is installed at the outer end of the branch pipe. A ball valve 11 is installed in the middle of the branch pipe. The second detector 10 detects the content of bacteria and other substances in the air and dirt inside the recovery tank 1 after steam sterilization to ensure that bacteria and other substances in the dirt are fully disinfected.
[0034] The valve stem of the ball valve 11 passes through the valve housing 13 and abuts against the fixing plate 16 of the valve stem handle 12. At least one first positioning block 14 and at least one second positioning block 15 are circumferentially spaced on the outer wall of the valve housing 13. A limiting side plate 17 extends from the side of the fixing plate 16 and abuts against either the first positioning block 14 or the second positioning block 15. When the valve stem handle 12 is rotated to the open position of the ball valve 11, the limiting side plate 17 abuts against the first positioning block 14 for positioning. When the ball valve 11 is closed, the limiting side plate 17 abuts against the second positioning block 15 for positioning, thereby ensuring the stability of the on / off state of the ball valve 11.
[0035] An angle steel 18 is installed at the bottom of the recycling tank 1, with both ends of the angle steel 18 fixed to the bottom surface of the recycling tank 1. A caster wheel 19 is installed at the bottom of the angle steel 18. The angle steel 18 is used to connect the recycling tank 1 and the caster wheel 19, thereby buffering the impact forces between the structures (ground impact and impact during the entry and exit of waste from the recycling tank 1) and improving the structural stability.
[0036] The working principle of the biosafety isolator waste recovery device in this embodiment includes: During use, the manual control valve 7 is adjusted so that waste is discharged from the isolator and enters the recovery tank 1. The value detected by the first detector 9 is checked. After the waste has completely entered the recovery tank 1, the manual control valve 7 is adjusted to close the delivery pipeline 2. High-temperature and high-pressure steam is introduced into the recovery tank 1 through the air inlet 5. At this time, the valve on the exhaust port 6 is closed. Referring to the value detected by the first detector 9, the waste in the recovery tank 1 is sterilized for the corresponding duration. After completion, the valve and ball valve 11 on the exhaust port 6 are opened, and the second detector 10 is used to detect the waste. If the detection result does not meet the standard, a second steam sterilization treatment is performed. Otherwise, clean airflow is introduced through the air inlet 5 so that the waste gas in the recovery tank 1 is discharged through the exhaust port 6 and treated by the waste gas treatment mechanism. After that, the cover 4 can be removed so that the waste in the recovery tank 1 is discharged through the slag discharge port 3 for unified treatment.
[0037] In summary, due to the adoption of the above technical solution, the biosafety isolator waste recovery device of this embodiment has the following advantages compared with the prior art:
[0038] This utility model's laboratory animal waste recovery device, through the design of air inlets and outlets and their connection to corresponding mechanisms, enables the sterilization of waste within the recovery tank, while simultaneously discharging waste gas and waste separately for further processing. The inclusion of a detection instrument further enhances the sterilization quality and efficiency, thereby improving waste treatment efficiency.
[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
