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] Anesthesia waste gas purification device is a device specially used to collect and purify anesthetic waste gas in operating room or anesthesia process. Its main purpose is to reduce and eliminate the pollution of volatile anesthetic drugs and their waste gas to the environment and ensure the safety of medical staff and patients.

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.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-Figure 6 This application is described in further detail.

[0030] 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 arranged on one side of the device body. A gas adsorption tank 2 is arranged on one side of the frame 1, and an air inlet pipe 3 and an air outlet pipe 4 are arranged on the gas adsorption tank 2. A plurality of adsorption chambers 5 are arranged 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 arranged in each adsorption chamber 5, and the plurality of partition plates 6 are evenly spaced along the circumference of the circle, and an independent chamber for placing activated carbon is formed between adjacent partition plates 6 and the inner wall of the gas adsorption tank 2. A quantitative equal distribution mechanism 7 is arranged 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 arranged 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.

[0031] 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 allow the incoming gas to be evenly distributed to avoid 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.

[0032] During the adsorption process of anesthetic waste gas, the rotating mechanism 8 will drive the multiple partitions 6 in each adsorption chamber 5 to rotate, and the partitions 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. And when the adsorption capacity of the activated carbon reaches saturation, the quantitative equal distribution mechanism 7 can, on the one hand, complete the rapid discharge of the activated carbon from the gas adsorption tank 2, and on the other hand, can quantitatively fill each independent chamber with new activated carbon to quickly complete the replacement of the activated carbon.

[0033] In some embodiments, reference Figure 2 The rotating mechanism 8 includes a support frame 81 fixedly arranged inside the gas adsorption tank 2, and a rotating shaft 82 is rotatably connected to the support frame 81, and the rotating shaft 82 is fixedly connected to the multiple partition plates 6 in each adsorption chamber 5. A transmission shaft 83 is rotatably connected to the side wall of the gas adsorption tank 2, and a driving motor 84 is arranged at the end of the transmission shaft 83. A bevel gear set 85 is arranged between the rotating shaft 82 and the transmission shaft 83.

[0034] When the driving 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, so as to realize 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 can be prevented from decreasing due to the long-term static state of the activated carbon, thereby reducing the replacement frequency of the activated carbon and reducing the operating cost and maintenance workload of the purification device.

[0035] In some embodiments, reference Figure 3 and Figure 4, the quantitative equalization mechanism 7 includes a quantitative taking tank 71 arranged on one side of the gas adsorption tank 2, and an equalization tank 72 is arranged between the quantitative taking tank 71 and the gas adsorption tank 2. A quantitative pipeline 73 is arranged between the equalization tank 72 and the quantitative taking tank 71, and a plurality of conveying pipelines 74 are arranged between the equalization tank 72 and the gas adsorption tank 2, and the plurality of conveying pipelines 74 correspond to the plurality of adsorption chambers 5 one by one; and a solenoid valve 75 is also arranged on the conveying pipeline 74. An equalization component 76 is arranged on the equalization tank 72, and the equalization component 76 is used to divide the activated carbon in the equalization tank 72 into multiple portions. A flip component 77 is arranged between the frame 1 and the quantitative taking tank 71, and the flip component 77 is used to drive the quantitative taking tank 71 and the equalization tank 72 to switch between a vertical placement state and a horizontal placement state. A discharge component 78 is arranged on the quantitative taking tank 71, and the discharge component 78 is used to open or close the quantitative taking tank 71 to discharge the activated carbon in the quantitative taking tank 71.

[0036] When the saturated or aged activated carbon needs to be replaced, first, the quantitative taking tank 71 and the equalizing tank 72 are driven to rotate to a horizontal position through the flip assembly 77, and then the quantitative taking tank 71 is opened through the discharge assembly 78 to discharge the saturated or aged activated carbon in the quantitative taking tank 71, and then the quantitative taking tank 71 is closed. Then the staff quantitatively puts the activated carbon into the equalizing tank 72 through the quantitative taking tank 71, and the equalizing assembly 76 divides the activated carbon into multiple portions in the equalizing tank 72 to ensure that the amount of activated carbon in each portion is consistent. The equally divided 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 the rotating mechanism 8 is cooperated to drive the multiple independent chambers in the same adsorption chamber 5 to rotate, so as to complete the filling of the activated carbon in all independent chambers, and finally the quantitative taking tank 71 and the equalizing tank 72 are driven to switch to a vertical position through the flip assembly 77.

The controller is connected to the electronic scale and the electric control valve 712, and is used to receive the weight detection signal to know the weight of the activated carbon in the taking tank body 711. When the weight is less than the preset weight, the controller sends a control signal to the electric control valve 712, so that the electric control valve 712 closes the quantitative pipeline 73.

[0038] When it is necessary to add activated carbon to the equal-dividing 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-controlled valve 712, and the electric-controlled valve 712 responds by closing the quantitative pipeline 73, and stopping adding activated carbon to the equal-dividing tank 72.

[0039] In some embodiments, reference Figure 3 and Figure 4 The dividing assembly 76 includes a plurality of dividing plates 761 which are parallel and spaced and plugged into the dividing tank 72, and a synchronization plate 762 is fixed between the plurality of dividing plates 761. An electric telescopic rod 763 is arranged between the synchronization plate 762 and the outer wall of the dividing tank 72. A vibration motor 764 is also arranged on the outer wall of the dividing tank 72. The vibration of the vibration motor 764 can promote the flow of the activated carbon in the dividing tank 72, so that the activated carbon is evenly distributed in the dividing tank 72, improve the accuracy of the activated carbon equalization, and ensure the consistency of the amount of each portion of activated carbon.

[0040] After the activated carbon in the quantitative extraction tank 71 enters the equal distribution tank 72, the upper surface of the activated carbon in the tank can be kept flat by shaking the equal distribution tank 72, and then the electric telescopic rod 763 is started.

When the solenoid valve 75 is opened, the equally divided activated carbon is transported to each independent chamber of the gas adsorption tank 2 through the transportation pipeline 74.

[0041] In some embodiments, reference Figure 5 and Figure 6 The flip assembly 77 includes a flip shaft 771 disposed 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 gear 772 are meshed with each other, and a power motor 774 is also disposed at one end of the worm gear 773, wherein the transmission of the worm gear 772 and the worm gear 773 is self-locking, and even if the power motor 774 stops working, the flip position of the gas adsorption tank 2 can be maintained to prevent it from rotating by itself due to gravity. Two first limit rods 775 are fixedly disposed on the frame 1 at intervals, and a second limit rod 776 is fixedly disposed on the flip shaft 771, and the second limit rod 776 is located between the two first limit rods 775.

[0042] When the power motor 774 is started, it drives the worm 773 to rotate, and the worm 773 transmits power to the worm wheel 772 and the flip shaft 771, so that the flip shaft 771 rotates, and the flip shaft 771 can drive the gas adsorption tank 2 to flip, so as to facilitate the cleaning and replacement of the adsorption chamber 5. When the flip shaft 771 rotates, when the second limit rod 776 contacts one of the first limit rods 775, it will limit the flip angle of the gas adsorption tank 2, so that the gas adsorption tank 2 remains in a horizontal state; when the second limit rod 776 contacts the other first limit rod 775, it will keep the gas adsorption tank 2 in a vertical state.

The rubber plugs 783 are used to enhance the sealing of the gas adsorption tank 2 to prevent the anesthetic waste gas from leaking from the discharge port 21 in a non-maintenance state.

[0044] When it is necessary to clean or replace the activated carbon in the adsorption chamber 5, the staff can open the buckle 782 to 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.

The multiple adsorption chambers 5 and the partition plate 6 inside the gas adsorption tank 2 allow the incoming gas to be evenly distributed to avoid 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 from the exhaust pipe.
