Description

Technical Field

[0001] The invention belongs to the technical field of high-temperature waste gas treatment, and in particular relates to an exhaust gas treatment device for a high-pressure sterilizing pot. Background Art

[0002] Sterilizer, usually refers to a high-pressure steam sterilizer, which is a device used to sterilize medical devices, surgical instruments, dressings, culture media, etc. High-pressure steam sterilizers use high-temperature and high-pressure steam to kill microorganisms, including bacteria, viruses, fungi, and spores. Steam is generated by heating water in a closed environment, and the steam is allowed to penetrate the items under a certain pressure, thereby achieving sterilization.

[0003] In order to ensure safety, especially when handling medical waste or highly contaminated items, the exhaust gas treatment of the sterilizer is still very important. For example, the Chinese utility model patent with the announcement number CN221206246U discloses a high-pressure sterilizer exhaust treatment device, which guides the exhaust gas through the exhaust device and then sterilizes the exhaust gas through the sterilizing liquid. The structure is simple, which can greatly reduce the production cost of the sterilizer and prevent the exhaust gas from polluting the atmosphere.

[0004] However, the exhaust gas generated by the sterilizer has a high temperature. When passing through the solution, it is easy to heat the solution and cause the solution to be lost. If the solution cannot be added in time, the exhaust gas will be insufficiently treated.

[0005] In summary, there is a need for a high-pressure sterilizer exhaust treatment device that can automatically add exhaust treatment liquid. Summary of the invention

[0006] The invention aims to provide an exhaust gas treatment device for a high-pressure sterilizing pot.

[0007] The technical solution adopted by the present invention to solve the above problem is: an exhaust gas treatment device for a high-pressure sterilizing pot, comprising: The autoclave body uses high-temperature and high-pressure steam to perform sterilization operations; A treatment assembly, which uses a treatment liquid to perform chemical purification treatment on the gas, the treatment assembly includes a treatment box, a discharge pipe arranged on the treatment box and used to discharge the treated gas, a transmitting probe arranged on the side of the treatment box, a receiver arranged on the side of the treatment box and located on the side opposite to the transmitting probe, a guide rod installed on the inner side of the treatment box, a floating plate sleeved on the guide rod, a stopper arranged on the top of the floating plate, and a liquid filling assembly arranged on the treatment box; After the receiver receives the optical signal emitted by the emitting probe, the liquid filling component adds the processing liquid into the processing box until the receiver cannot receive the optical signal emitted by the emitting probe; The average density of the assembly formed by the floating plate and the block is less than the density of the treatment liquid; The floating plate is provided with a plurality of vertically oriented ventilation holes; The processing box is connected to the sterilizing pot body through an exhaust pipe.

[0008] The processing box provides a closed environment for gas processing, in which chemical purification is carried out to ensure the cleanliness of the treated gas, and the exhaust pipe is used to safely discharge the purified gas after treatment into the external environment.

[0009] The transmitting probe and the receiver form a detection system. The transmitting probe transmits an optical signal and the receiver is used to receive the optical signal.

[0010] The floating plate moves up and down in the treatment liquid as the liquid level changes. The guide rod ensures that the floating plate can move in the vertical direction to accurately reflect the change in liquid level. The stopper is combined with the floating plate to form a floating device. When the treatment liquid level drops to a certain level, the stopper no longer blocks the transmission of the optical signal emitted by the transmitting probe, and sends a signal to the filling component to add treatment liquid.

[0011] In particular, the vent holes provided on the floating plate can ensure that the gas discharged from the high-pressure sterilizer, after entering the processing box, the generated airflow will not cause the floating plate to turbulently move up and down, so as to avoid the block losing its shielding of the transmitting probe during the turbulence, thereby causing the liquid filling component to be falsely triggered.

[0012] A further preferred technical solution is that: the sterilizing pot body comprises a sterilizing cylinder, an exhaust ring arranged on the top of the sterilizing cylinder, and a pot cover arranged on the top of the exhaust ring; The exhaust pipe is in communication with the exhaust ring.

[0013] A further preferred technical solution is that: a cooling assembly is installed on the exhaust pipe; the cooling assembly includes a cooling box fixedly connected to the sterilization cylinder and sleeved on the outside of the exhaust pipe, a liquid inlet pipe and a return pipe arranged on the side of the cooling box, a refrigeration box arranged on the return pipe, a refrigeration plate installed on the inside of the refrigeration box, and a pump arranged on the top of the refrigeration box; The input end of the pump passes through the top of the refrigeration box and extends to the inner bottom of the refrigeration box.

[0014] A further preferred technical solution is that: the liquid filling assembly includes a liquid storage tank, a liquid discharge pipe connecting the liquid storage tank and the processing tank, an electromagnetic valve disposed on the liquid discharge pipe, and a processor for opening and closing the electromagnetic valve; The receiver and the electromagnetic valve are both electrically connected to the processor via lines.

[0015] A further preferred technical solution is that the block has a density of 0.03-0.05 g / cm 3 Foaming materials within the range.

[0016] A further preferred technical solution is that: the top of the liquid storage tank is connected to a liquid pouring pipe, and a sealing cover is installed on the top of the liquid pouring pipe.

[0017] A further preferred technical solution is that: a mounting block is sleeved on the exhaust pipe, and the back of the mounting block is fixedly connected to the sterilization cylinder.

[0018] A further preferred technical solution is that a control valve is installed on the exhaust pipe.

[0019] A further preferred technical solution is that: a plurality of exhaust ports are provided at intervals on the inner wall of the exhaust ring, and an annular cavity is formed inside the exhaust ring.

[0020] A further preferred technical solution is that: a support rod is fixedly connected to the side of the refrigeration plate, and one end of the support rod is fixedly connected to the inner wall of the refrigeration box.

[0021] In summary, the present invention has the following benefits: 1. The present invention sets a processing component, and the gas in the exhaust pipe is discharged into the treatment liquid inside the treatment box, and the gas is processed. The treated gas is then discharged through the exhaust pipe. In this process, when the treatment liquid is less, the floating plate will descend with the block, so that the transmitting probe irradiates the receiver, and the receiver transmits the signal to the processor. The processor transmits the signal to the electromagnetic valve through the line, so that the electromagnetic valve opens, and the treatment liquid in the liquid storage tank flows to the inside of the treatment box. After the treatment liquid is increased, the block blocks the transmitting probe again, and the processor closes the electromagnetic valve and stops adding the treatment liquid. The above process automatically adds the treatment liquid to the treatment box.

[0022] 2. The present invention provides a plurality of vent holes on the floating plate to ensure that after the gas discharged from the high-pressure sterilizer enters the processing box, the airflow generated will not cause the floating plate to turbulently move up and down, so as to prevent the block from losing its shielding of the transmitting probe during the turbulence, thereby preventing the liquid filling component from being falsely triggered.

[0023] 3. The present invention sets a cooling component. During the process of discharging gas, the pump and the refrigeration plate are started. The pump transports the water in the refrigeration box to the inside of the cooling box through the liquid inlet pipe. The water in the cooling box exchanges heat with the surface of the exhaust pipe, thereby reducing the stability of the gas in the exhaust pipe. The water in the cooling box is transported to the inside of the refrigeration box through the return pipe. Through the cooperation of the pump, the liquid inlet pipe and the return pipe, the continuous flow exchange of the water body in the cooling box and the refrigeration box is realized. At the same time, under the action of the refrigeration plate, the temperature of the water body is maintained at a relatively low degree, which can continuously exchange heat with the gas in the exhaust pipe. The cooled gas can further reduce the evaporation effect on the treatment liquid. BRIEF DESCRIPTION OF THE DRAWINGS

After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.

[0028] Example:

[0029] Please combine Figure 1-Figure 3 , a high pressure sterilizing pot exhaust treatment device of this embodiment includes The autoclave body uses high-temperature and high-pressure steam to perform sterilization operations; A treatment component, which uses a treatment liquid to perform chemical purification treatment on the gas, the treatment component includes a treatment box 11, a discharge pipe arranged on the treatment box 11 and used to discharge the treated gas, a transmitting probe 12 arranged on the side of the treatment box 11, a receiver 13 arranged on the side of the treatment box 11 and located on the opposite side of the transmitting probe 12, a guide rod 14 installed on the inner side of the treatment box 11, a floating plate 15 sleeved on the guide rod 14, a stopper 16 arranged on the top of the floating plate 15, and a liquid filling component arranged on the treatment box 11; After the receiver 13 receives the optical signal emitted by the transmitting probe 12, the liquid filling component is instructed to add the processing liquid into the processing box 11 until the receiver 13 can no longer receive the optical signal emitted by the transmitting probe 12; The average density of the assembly formed by the floating plate 15 and the stopper 16 is less than the density of the treatment liquid; The floating plate 15 is provided with a plurality of vertically oriented ventilation holes; The processing box 11 is connected to the sterilizing pot body through the exhaust pipe 4.

[0030] The treatment liquid usually depends on the specific application requirements and the gas components that need to be removed. In this embodiment, the treatment liquid is sodium hypochlorite, which has a broad-spectrum bactericidal effect.

[0031] In a preferred embodiment, the treatment liquid is hydrogen peroxide, which is used to kill bacteria, viruses and spores and has strong oxidizing properties.

[0032] In a preferred embodiment, the treatment liquid is a quaternary ammonium salt compound.

[0033] In a preferred embodiment, the treatment liquid is an alcohol compound, specifically ethanol or isopropanol.

[0034] A plurality of vertically oriented vents are provided on the floating board 15, which means that these vents are perpendicular to the surface of the floating board, that is, the axes of these holes are perpendicular to the plane of the floating board, and the opening direction of the vents is vertically upward. This design aims to ensure that gas can be discharged or entered vertically through the holes on the floating board, thereby achieving exhaust, reducing the direct effect of airflow on the floating board 15, helping to manage the flow direction of gas, and reducing the impact of turbulence on the floating board 15.

[0035] The material constituting the floating plate 15 and the stopper 16 should have a density lower than that of the treatment liquid and good chemical corrosion resistance and structural strength. In this embodiment, the floating plate 15 and the stopper 16 are made of foamed polypropylene.

[0036] In a preferred embodiment, the floating plate 15 and the stopper 16 are made of foamed polypropylene.

[0037] In a preferred embodiment, the density of the stopper 16 is 0.03 g / cm 3 Since the volume of the stopper 16 is significantly larger than that of the floating plate 15, when the stopper 16 is made of a material with a lower density, it can further ensure that the floating plate 15 floats on the upper surface of the liquid.

[0038] In the present embodiment, the main body of the sterilizing pot is specifically a sterilizing cylinder 1, and an exhaust ring 2 is fixedly connected to the top of the sterilizing cylinder 1.

A cooling component is installed on the surface of the exhaust pipe 4, and a processing component is installed at the bottom of the exhaust pipe 4.

[0039] In this embodiment, the cooling component is used to cool the gas, specifically a cooling box 5 fixedly connected to the sterilization cylinder 1, the cooling box 5 is sleeved on the outside of the exhaust pipe 4, the side of the cooling box 5 is connected with a liquid inlet pipe 6 and a return pipe 7, the return pipe 7 is connected with a refrigeration box 8, a refrigeration plate 9 is installed inside the refrigeration box 8, two support rods are fixedly connected to the refrigeration plate 9, one end of the support rod is fixedly connected to the inner wall of the refrigeration box 8, to ensure the normal operation of the refrigeration plate 9, a pump 10 is installed on the top of the refrigeration box 8, the input end of the pump 10 passes through the top of the refrigeration box 8 and abuts against the bottom of the inner wall of the refrigeration box 8, and the output end of the pump 10 is connected to the end of the liquid inlet pipe 6.

[0040] The refrigeration box 8 is installed on the return pipe to reduce the temperature of the returned cooling medium to ensure that it has sufficient cooling effect when entering the cooling box. The cooling plate 9 is located inside the refrigeration box 8 to provide cooling capacity. It is usually composed of a thermoelectric cooling plate or other cooling device to reduce the internal temperature of the refrigeration box. The pump 10 is responsible for pumping the cooling medium in the refrigeration box into the liquid inlet pipe to ensure the circulation of the cooling medium, thereby maintaining the operation of the cooling system.

[0041] In this embodiment, the processing component performs chemical purification on the gas through the processing liquid, specifically, the processing box 11, the processing box 11 is connected with a discharge pipe to facilitate the discharge of the treated gas, the processing box 11 is connected with the bottom end of the exhaust pipe 4, the side of the processing box 11 is installed with a transmitting probe 12, the processing box 11 is installed with a receiver 13 on the side opposite to the transmitting probe 12, four guide rods 14 are installed inside the processing box 11, the outer side of the guide rod 14 is provided with a floating plate 15, the top of the floating plate 15 is fixedly connected with a stopper 16, the stopper 16 is a lightweight foam board, which ensures that the floating plate 15 can always be located at the liquid surface, and the side of the processing box 11 The bottom of the refrigeration box 8 is connected to a discharge pipe 17, and an electromagnetic valve 18 is installed on the surface of the discharge pipe 17. One end of the discharge pipe 17 is connected to a liquid storage tank 19. The four corners of the bottom of the liquid storage tank 19 are fixedly connected with pads to facilitate the treatment liquid in the liquid storage tank 19 to flow to the treatment tank 11. The top of the liquid storage tank 19 is connected to a liquid pouring pipe, and a sealing cover is installed on the top of the liquid pouring pipe to facilitate adding treatment liquid to the liquid storage tank 19. The bottom of the refrigeration box 8 is installed on the top of the liquid storage tank 19, and a processor 20 is installed on the front of the liquid storage tank 19. The receiver 13 and the electromagnetic valve 18 are electrically connected to the processor 20 through lines, so that the electromagnetic valve 18 can be controlled by the processor 20.

[0042] In this embodiment, the transmitting probe 12 is a photoelectric sensor or a laser transmitting device for transmitting a light beam or a laser signal.

[0043] In this embodiment, the receiver 13 is at the same level as the transmitting probe 12, and is used to receive the signal transmitted from the transmitting probe 12. When the position changes of the floating board and the block cause the signal to be blocked or received, the receiver can detect this change.

[0044] In this embodiment, the processor 20 is responsible for processing the signal from the receiver. When the receiver detects a signal change, such as when the signal is blocked or received again, the processor analyzes the signal change and makes corresponding control decisions.

[0045] In this embodiment, the solenoid valve 18 is an actuator controlled by a processor. When the processor receives a signal that a treatment liquid needs to be added, it activates the solenoid valve to open, thereby allowing the treatment liquid in the storage tank to flow into the treatment tank. When no addition is required, the processor closes the solenoid valve to stop the flow of the treatment liquid.

[0046] The implementation principle of an exhaust treatment device for a high-pressure sterilizer in the embodiment of the present application is: the gas in the sterilization cylinder 1 is discharged to the inside of the treatment box 11 through the exhaust ring 2 and the exhaust pipe 4 for treatment and discharge.

[0047] During the process of discharging gas, the pump 10 and the refrigeration plate 9 are started. The pump 10 transports the water in the refrigeration box 8 to the inside of the cooling box 5 through the liquid inlet pipe 6. The water in the cooling box 5 exchanges heat with the surface of the exhaust pipe 4, thereby reducing the temperature of the gas in the exhaust pipe 4. The water in the cooling box 5 is then transported to the inside of the refrigeration box 8 through the return pipe 7. Through the cooperation of the pump 10, the liquid inlet pipe 6 and the return pipe 7, a continuous flow exchange of the water bodies in the cooling box 5 and the refrigeration box 8 is achieved. At the same time, under the action of the refrigeration plate 9, the temperature of the water body is maintained at a relatively low level, so that the gas in the exhaust pipe 4 can be continuously cooled.

[0048] The gas in the exhaust pipe 4 is discharged into the treatment liquid inside the treatment box 11, and the gas is treated. The treated gas is then discharged through the exhaust pipe. In this process, when the treatment liquid is less, the floating plate 15 will descend with the block 16, so that the transmitting probe 12 is irradiated onto the receiver 13, and the receiver 13 transmits the signal to the processor 20. The processor 20 transmits the signal to the solenoid valve 18 through the line, so that the solenoid valve 18 opens, and the treatment liquid in the liquid storage tank 19 flows to the inside of the treatment box 11. When the block 16 blocks the transmitting probe 12 again, the solenoid valve 18 is closed through the control of the processor 20, so that the treatment liquid is automatically added to the treatment box 11.
