Description

Technical Field

[0001] The present application relates to the technical field of anesthetic waste gas purification, and in particular to an anesthetic waste gas purification device. Background Art

[0002] An anesthetic waste gas purification device is a device specifically designed to collect and purify anesthetic waste gas in operating rooms or during anesthesia. Its main purpose is to reduce and eliminate environmental pollution caused by volatile anesthetic drugs and their waste gas, ensuring the safety of medical staff and patients.

[0003] At present, the anesthetic waste gas purification device mainly includes a vacuum pump that sucks the anesthetic waste gas in the operating room through negative pressure, an air intake pipe, a primary filter for filtering particulate impurities in the anesthetic waste gas, a gas filter that adsorbs anesthetic waste gas and organic volatiles, an air pressure buffer unit, a vacuum solenoid valve for controlling waste gas emissions, and a monitoring device for real-time monitoring of the concentration of anesthetic waste gas; during purification, first, a negative pressure is generated by a vacuum pump to suck the anesthetic waste gas generated in the operating room into the air intake pipe, and then the anesthetic waste gas passes through the primary filter to remove particulate impurities in the waste gas, such as dust, and the waste gas after primary filtration enters the gas filter to adsorb organic volatiles in the anesthetic waste gas, such as anesthetic drug molecules. The air pressure buffer unit is used to stabilize the air pressure in the system to ensure the smooth progress of the purification process. The vacuum solenoid valve is used to accurately control the emission of waste gas to ensure that the purified waste gas is discharged under safe conditions.

[0004] The gas filter is the core part of the purification device, which includes activated carbon filter media, a shell for accommodating the filter media, and an air inlet and outlet arranged on the outer shell. However, the activated carbon accumulates in the shell, and the anesthetic waste gas is unevenly distributed after entering the shell. The amount of activated carbon in some areas that contacts the gas is small, resulting in its adsorption capacity not being fully utilized, or the local activated carbon accumulation is too thick, the resistance to gas passing through increases, and the internal activated carbon is not fully utilized, affecting the adsorption purification efficiency. Summary of the Invention

The multiple adsorption chambers and partitions inside the gas adsorption tank enable the incoming gas to be evenly distributed, avoiding uneven adsorption of activated carbon caused by local excess gas. When the gas passes through each independent chamber, it fully contacts the activated carbon placed between the partition plate and the inner wall of the gas adsorption tank, and the organic volatiles are fully adsorbed by the activated carbon and then discharged through the air outlet pipe.

The equalized activated carbon is transported to each adsorption tank on the upper side through multiple conveying pipes. In the independent chambers in the chamber, the rotating mechanism is then used to drive multiple independent chambers in the same adsorption chamber to rotate, completing the filling of activated carbon in all independent chambers, and finally the quantitative taking tank and the equal distribution tank are driven to switch to a vertical placement state through the flipping assembly; the equal distribution assembly and the flipping assembly are used in conjunction with the rotating assembly to quickly complete the filling of activated carbon in each independent chamber, and keep the filling amount consistent, and the flipping assembly and the discharge assembly are used in conjunction with the rotating assembly to quickly complete the discharge of saturated or aged and inactivated activated carbon in each independent chamber, thereby improving the utilization rate of activated carbon and the gas purification efficiency.

When the solenoid valve is opened, the equally divided activated carbon is transported to the independent chambers of the gas adsorption tank through the delivery pipeline.

[0027] Optionally, a vibration motor is provided on the outer side wall of the aliquot tank.

[0028] By adopting the above technical solution, the vibration of the vibration motor can promote the flow of activated carbon in the equal-division tank, so that the activated carbon is evenly distributed in the equal-division tank, improve the accuracy of activated carbon equalization, and ensure the consistency of the amount of activated carbon in each portion.

When the flip axis rotates, when the second limit rod contacts one of the first limit rods, it will limit the flipping angle of the gas adsorption tank, so that the gas adsorption tank remains in a horizontal state; when the second limit rod contacts the other first limit rod, the gas adsorption tank will remain in a vertical state; the coordinated use of the first limit rod and the second limit rod can ensure that the gas adsorption tank can be stably positioned when flipped to the specified position, thereby improving the convenience and accuracy of the staff's operation.

[0036] Optionally, the discharge assembly includes:

[0037] A baffle, hinged to the outer side wall of the gas adsorption tank;

[0047] The controller is connected to the electronic scale and the electric control valve, and is used to receive a weight detection signal to know the weight of the activated carbon taken from the tank. When the weight is less than a preset weight, the controller sends a control signal to the electric control valve to make the electric control valve close the quantitative pipeline.

[0048] By adopting the above technical solution, when it is necessary to add activated carbon to the aliquot tank, the electronic scale is connected to the taking tank body, and the weight of the activated carbon in the taking tank body is detected in real time, and a weight detection signal is sent to the controller. When the weight detection signal received by the controller shows that the weight of the activated carbon in the taking tank body is less than the preset weight, the controller sends a control signal to the electric control valve, and the electric control valve responds to close the quantitative pipeline and stop adding activated carbon to the aliquot tank; through the coordinated use of the electronic scale, the controller and the electric control valve, the amount of activated carbon added to the aliquot tank can be accurately controlled to avoid excessive or insufficient addition.

[0049] Optionally, the rotating mechanism includes:

The frequency of replacing the activated carbon is reduced, the operating cost and maintenance workload of the purification device are reduced, and it also helps to evenly distribute the activated carbon in the adsorption chamber, thereby improving the uniformity and stability of gas purification.

[0055] In summary, this application includes at least one of the following beneficial technical effects:

[0056] 1. During the adsorption process of anesthetic waste gas, the rotating mechanism drives the multiple partition plates in each adsorption chamber to rotate. The partition plates drive the activated carbon to tumble and move, allowing the gas to flow more evenly through each independent chamber when passing through the gas adsorption tank, so that the activated carbon in the gas filter is fully utilized, further improving the contact efficiency between the gas and the activated carbon and the purification efficiency; and when the activated carbon adsorption capacity reaches saturation, the quantitative equalization mechanism can not only quickly discharge the activated carbon from the gas adsorption tank, but also quantitatively fill each independent chamber with new activated carbon, quickly completing the replacement of the activated carbon and improving the purification efficiency;

[0057] 2. The medium dividing component and the flip component in the quantitative equal dividing mechanism, together with the rotating component, can quickly complete the filling of activated carbon in each independent chamber and keep the filling amount consistent. The flip component and the discharge component, together with the rotating component, can quickly complete the discharge of saturated or aged deactivated activated carbon in each independent chamber, thereby improving the utilization rate of activated carbon and gas purification efficiency.

[0058] 3. The electric telescopic rod in the equalization component can drive the synchronous plate and multiple equalization plates to evenly divide the activated carbon into multiple portions, ensuring the uniform distribution of the activated carbon during the subsequent transportation process. In addition, the vibration of the vibration motor can promote the flow of the activated carbon in the equalization tank, so that the activated carbon is evenly distributed in the equalization tank, improve the accuracy of the activated carbon equalization, and ensure the consistency of the amount of activated carbon in each portion;

[0059] 4. The flip assembly is self-locking. Even if the power motor stops working, it can maintain the flip position of the gas adsorption tank, preventing it from rotating on its own due to gravity, thereby improving the stability and safety of the equipment. When the second limit rod contacts one of the first limit rods, it will limit the flip angle of the gas adsorption tank, so that the gas adsorption tank remains in a horizontal state; when the second limit rod contacts the other first limit rod, it will keep the gas adsorption tank in a vertical state. The coordinated use of the first limit rod and the second limit rod can ensure that the gas adsorption tank can be stably positioned when flipped to the specified position, thereby improving the convenience and accuracy of the operator's operation.

[0060] 5. By regularly turning the activated carbon in the rotating mechanism, the adsorption efficiency can be prevented from decreasing due to long-term static activation, which reduces the replacement frequency of the activated carbon, reduces the operating cost and maintenance workload of the purification device, and also helps to evenly distribute the activated carbon in the adsorption chamber, thereby improving the uniformity and stability of gas purification.

DETAILED DESCRIPTION

[0068] The following is combined with Figures 1-6 This application is described in further detail.

[0069] The present application embodiment discloses an anesthetic waste gas purification device. Figure 1 and Figure 2 The anesthetic waste gas purification device includes a device body, and a frame 1 is provided on one side of the device body. A gas adsorption tank 2 is provided on one side of the frame 1, and an air inlet pipe 3 and an air outlet pipe 4 are provided on the gas adsorption tank 2. A plurality of adsorption chambers 5 are provided inside the gas adsorption tank 2 along its length direction, and the plurality of adsorption chambers 5 are connected. A plurality of partition plates 6 are provided in each adsorption chamber 5, and the plurality of partition plates 6 are evenly spaced along the circumference of the circle, and independent chambers for placing activated carbon are formed between adjacent partition plates 6 and the inner wall of the gas adsorption tank 2. A quantitative equal distribution mechanism 7 is provided between the gas adsorption tank 2 and the frame 1, and the quantitative equal distribution mechanism 7 is used to quantitatively add activated carbon to each independent chamber and replace the activated carbon. A rotating mechanism 8 is provided between the gas adsorption tank 2 and the partition plate 6, and the rotating mechanism 8 is used to drive the partition plate 6 to rotate.

[0070] The anesthetic waste gas in the operating room enters the gas adsorption tank 2 through the air intake pipe 3 under the negative pressure of the vacuum pump. The multiple adsorption chambers 5 and partition plates 6 inside the gas adsorption tank 2 enable the incoming gas to be evenly distributed, avoiding uneven adsorption of activated carbon caused by local excess gas. When the gas passes through each independent chamber, it is fully in contact with the activated carbon placed between the partition plate 6 and the inner wall of the gas adsorption tank 2. The organic volatiles are fully adsorbed by the activated carbon and then discharged through the exhaust pipe.

[0071] During the adsorption process of anesthetic waste gas, the rotating mechanism 8 rotates the multiple partitions 6 within each adsorption chamber 5. These partitions cause the activated carbon to tumble and move, allowing the gas to flow more evenly through each independent chamber as it passes through the gas adsorption tank 2, fully utilizing the activated carbon in the gas filter. When the activated carbon's adsorption capacity reaches saturation, the quantitative aliquoting mechanism 7 rapidly discharges the activated carbon from the gas adsorption tank 2 while simultaneously quantitatively filling each independent chamber with new activated carbon, rapidly completing the replacement process.

[0072] In some embodiments, reference Figure 2 The rotating mechanism 8 includes a support frame 81 fixedly mounted within the gas adsorption tank 2. A rotating shaft 82 is rotatably connected to the support frame 81. The rotating shaft 82 is fixedly connected to the multiple partitions 6 in each adsorption chamber 5. A transmission shaft 83 is rotatably connected to the side wall of the gas adsorption tank 2. A drive motor 84 is provided at the end of the transmission shaft 83. A bevel gear set 85 is disposed between the rotating shaft 82 and the transmission shaft 83.

[0073] When the drive motor 84 is started, the transmission shaft 83 rotates accordingly, and the power is transmitted to the rotating shaft 82 through the transmission shaft 83 and the bevel gear set 85. Then the rotating shaft 82 drives the partition plate 6 in the adsorption chamber 5 to flip, thereby realizing the flipping of the activated carbon in the adsorption chamber 5, so that the exhaust gas and the activated carbon are fully in contact, thereby improving the gas purification efficiency. By regularly flipping the activated carbon, the adsorption efficiency of the activated carbon can be avoided from decreasing due to long-term static state, thereby reducing the frequency of replacing the activated carbon and reducing the operating cost and maintenance workload of the purification device.

[0074] In some embodiments, reference Figure 3 and Figure 4 The quantitative equalization mechanism 7 includes a quantitative withdrawal tank 71 arranged on one side of the gas adsorption tank 2, and an equalization tank 72 is arranged between the quantitative withdrawal tank 71 and the gas adsorption tank 2. A quantitative pipeline 73 is arranged between the equalization tank 72 and the quantitative withdrawal tank 71, and multiple delivery pipelines 74 are arranged between the equalization tank 72 and the gas adsorption tank 2. The multiple delivery pipelines 74 correspond one-to-one to the multiple adsorption chambers 5; a solenoid valve 75 is also arranged on the delivery pipeline 74. An equalization component 76 is provided on the equalization tank 72, and the equalization component 76 is used to divide the activated carbon in the equalization tank 72 into multiple equal portions. A flip component 77 is provided between the frame 1 and the quantitative withdrawal tank 71, and the flip component 77 is used to drive the quantitative withdrawal tank 71 and the equalization tank 72 to switch between a vertical placement state and a horizontal placement state. A discharge component 78 is provided on the quantitative withdrawal tank 71, and the discharge component 78 is used to open or close the quantitative withdrawal tank 71 to discharge the activated carbon in the quantitative withdrawal tank 71.

[0075] When the saturated or aged activated carbon needs to be replaced, the quantitative withdrawal tank 71 and the equalization tank 72 are first rotated to a horizontal position by the flip assembly 77, and then the quantitative withdrawal tank 71 is opened by the discharge assembly 78 to discharge the saturated or aged activated carbon in the quantitative withdrawal tank 71, and then the quantitative withdrawal tank 71 is closed. Then the staff quantitatively lowers the activated carbon into the equalization tank 72 through the quantitative withdrawal tank 71, and the equalization assembly 76 divides the activated carbon into multiple portions in the equalization tank 72 to ensure that the amount of activated carbon in each portion is consistent. The equalized activated carbon is transported to the independent chambers in each adsorption chamber 5 of the gas adsorption tank 2 through multiple conveying pipes 74, and then cooperates with the rotating mechanism 8 to drive the multiple independent chambers in the same adsorption chamber 5 to rotate, completing the filling of the activated carbon in all independent chambers. Finally, the quantitative withdrawal tank 71 and the equalization tank 72 are switched to a vertical position by the flip assembly 77.

[0076] In some embodiments, reference Figure 3 and Figure 4 The quantitative dispensing tank 71 includes a dispensing tank body 711, an electrically controlled valve 712 disposed on a quantitative pipe 73, an electronic scale, and a controller. The electronic scale is connected to the dispensing tank body 711 and is used to detect the weight of the activated carbon in the dispensing tank body 711 and issue a weight detection signal. The controller is connected to the electronic scale and the electrically controlled valve 712 and is used to receive the weight detection signal to determine the weight of the activated carbon in the dispensing tank body 711. When the weight is less than a preset weight, the controller issues a control signal to the electrically controlled valve 712, causing the electrically controlled valve 712 to close the quantitative pipe 73.

[0077] When activated carbon needs to be added to the aliquot tank 72, the electronic scale is connected to the taking tank body 711, and the weight of the activated carbon in the taking tank body 711 is detected in real time, and a weight detection signal is sent to the controller. When the weight detection signal received by the controller shows that the weight of the activated carbon in the taking tank body 711 is less than the preset weight, the controller sends a control signal to the electric control valve 712, and the electric control valve 712 responds by closing the quantitative pipe 73 and stopping adding activated carbon to the aliquot tank 72.

[0078] In some embodiments, reference Figure 3 and Figure 4 The aliquoting assembly 76 includes a plurality of parallel aliquoting plates 761 spaced apart and inserted into the aliquoting tank 72. Synchronizing plates 762 are fixedly positioned between the aliquoting plates 761. An electric telescopic rod 763 is positioned between the synchronizing plates 762 and the outer wall of the aliquoting tank 72. A vibration motor 764 is also positioned on the outer wall of the aliquoting tank 72. The vibration of the vibration motor 764 promotes the flow of activated carbon within the aliquoting tank 72, evenly distributing the activated carbon within the aliquoting tank 72, improving the accuracy of activated carbon aliquoting and ensuring a consistent amount of activated carbon in each portion.

[0079] After the activated carbon in the quantitative extraction tank 71 enters the equal division tank 72, the upper surface of the activated carbon in the tank can be kept flat by shaking the equal division tank 72, and then the electric telescopic rod 763 is started. The electric telescopic rod 763 drives the synchronous plate 762 and multiple equal division plates 761 to evenly divide the activated carbon into multiple parts, ensuring the uniform distribution of the activated carbon in the subsequent transportation process; the solenoid valve 75 controls the opening and closing of the delivery pipe 74. When the solenoid valve 75 is opened, the equally divided activated carbon is transported to the independent chambers of the gas adsorption tank 2 through the delivery pipe 74.

[0080] In some embodiments, reference Figure 5 and Figure 6 The flip assembly 77 includes a flip shaft 771 arranged between the frame 1 and the gas adsorption tank 2, one end of the flip shaft 771 is rotatably connected to the frame 1, and the other end is fixedly connected to the gas adsorption tank 2. A worm gear 772 is fixedly sleeved on the outer wall of the flip shaft 771, and a worm 773 is rotatably connected to the frame 1. The worm 773 and the worm wheel 772 are meshed with each other, and a power motor 774 is also provided at one end of the worm 773, wherein the worm wheel 772 and worm 773 transmission has a self-locking property. Even if the power motor 774 stops working, it can maintain the flip position of the gas adsorption tank 2 to prevent it from rotating by itself due to gravity. Two first limit rods 775 are fixedly provided on the frame 1 at intervals, and a second limit rod 776 is fixedly provided on the flip shaft 771. The second limit rod 776 is located between the two first limit rods 775.

[0081] When the power motor 774 is started, it drives the worm 773 to rotate. The worm 773 transmits power to the worm wheel 772 and the tilt shaft 771, causing the tilt shaft 771 to rotate. The tilt shaft 771 then drives the gas adsorption tank 2 to flip, thereby facilitating the cleaning and replacement of the activated carbon in the adsorption chamber 5. Furthermore, when the tilt shaft 771 rotates, when the second limiting rod 776 contacts one of the first limiting rods 775, it limits the tilting angle of the gas adsorption tank 2, keeping the gas adsorption tank 2 horizontal. When the second limiting rod 776 contacts the other first limiting rod 775, it keeps the gas adsorption tank 2 vertical.

[0082] In some embodiments, reference Figure 5 The discharge assembly 78 includes a baffle 781 hingedly connected to the outer wall of the gas adsorption tank 2. A buckle 782 is provided between the baffle 781 and the outer wall of the gas adsorption tank 2. The gas adsorption tank 2 is provided with multiple discharge ports 21, each corresponding to a plurality of adsorption chambers 5. The baffle 781 abuts against one side of the discharge port 21. The baffle 781 is fixed with multiple rubber plugs 783 corresponding to the discharge ports 21. The rubber plugs 783 are inserted into the discharge ports 21 to enhance the sealing of the gas adsorption tank 2 and prevent the leakage of anesthetic waste gas from the discharge port 21 when not in a maintenance state.

[0083] When the activated carbon in the adsorption chamber 5 needs to be cleaned or replaced, the staff can open the buckle 782 and rotate the baffle 781 around the hinge point to open the discharge port 21, thereby facilitating the cleaning of the adsorption chamber 5 and the replacement of the activated carbon.

[0084] The implementation principle of an anesthetic waste gas purification device in the embodiment of the present application is as follows: the anesthetic waste gas in the operating room enters the gas adsorption tank 2 through the air inlet pipe 3 under the negative pressure of the vacuum pump. The multiple adsorption chambers 5 and the partition plate 6 inside the gas adsorption tank 2 enable the incoming gas to be evenly distributed, avoiding uneven adsorption of activated carbon caused by local excess gas. When the gas passes through each independent chamber, it fully contacts the activated carbon placed between the partition plate 6 and the inner wall of the gas adsorption tank 2. The organic volatiles are fully adsorbed by the activated carbon and then discharged through the exhaust pipe. In the adsorption process of the anesthetic waste gas, the rotary The rotating mechanism 8 will drive the multiple partition plates 6 in each adsorption chamber 5 to rotate, and the partition plates 6 will drive the activated carbon to roll and move, so that the gas can flow through each independent chamber more evenly when passing through the gas adsorption tank 2, so that the activated carbon in the gas filter can be fully utilized, further improving the contact efficiency and purification efficiency between the gas and the activated carbon; and when the adsorption capacity of the activated carbon reaches saturation, the quantitative equal distribution mechanism 7 can, on the one hand, quickly discharge the activated carbon from the gas adsorption tank 2, and on the other hand, quantitatively fill each independent chamber with new activated carbon, quickly complete the replacement of the activated carbon, and improve the purification efficiency.

[0085] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
