[0010] Preferably, the processing chamber includes a cooling chamber, the outer wall of which is fixedly connected to the inner wall of the processing chamber, and a cooling pipe is fixedly connected to the inner wall of the cooling chamber. The front end of the cooling pipe is connected to the transmission pipeline, and the end of the cooling pipe is connected to the interior of the processing chamber.
[0011] Preferably, the processing chamber further includes a reaction vessel, the bottom end of which is fixedly connected to the bottom wall of the processing chamber.

Then, by using the connecting rod, the up and down movement of the sliding block drives the stirring drum to rotate continuously, thereby stirring and mixing the liquid and increasing the reaction effect.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0024] Please see Figures 1 to 5 The present invention provides a technical solution: a waste liquid treatment device for biomedicine, including a device shell 1, an evaporation chamber 2 is provided inside the device shell 1, an anti-backflow mechanism 3 is fixedly connected to the top of the evaporation chamber 2, and a treatment chamber 4 is provided inside the device shell 1, the treatment chamber 4 and the evaporation chamber 2 are arranged horizontally.
[0025] The anti-backflow mechanism 3 includes a transmission chamber 31, an air guide trough 38, and a guide member 39. The outer wall of the transmission chamber 31 is fixedly connected to the top wall of the outer casing 1. An air inlet pipe 32 is connected to the bottom wall of the transmission chamber 31. A transmission pipe 33 is connected to the top of the air inlet pipe 32. The bottom end of the air inlet pipe 32 is connected to the interior of the evaporation chamber 2. Telescopic rods 34 are fixedly installed on the inner walls of both ends of the air inlet pipe 32. Hydraulic oil is filled between the telescopic end and the moving end of the telescopic rod 34. A ring 35 is fixedly connected to the bottom end of both sets of telescopic rods 34. Both ends of the ring 35 are slidably installed with the inner sides of the air inlet pipe 32. Connecting rods 36 are fixedly installed at the top ends of both sides of the ring 35. All are fixedly connected with a blocking plate 37. The outer diameter of the blocking plate 37 matches the inner diameter of the air inlet pipe 32. The air guide groove 38 is opened on the side wall of the air inlet pipe 32. One end of the guide 39 is connected to the side wall of the air inlet pipe 32. When the equipment stops working, the components inside the transmission chamber 31 gradually cool down. At this time, as the temperature drops, the residual condensate will extend to the transmission pipe 33 for backflow. However, due to the temperature drop, the hydraulic oil in the telescopic rod 34 cools down and depressurizes. The telescopic rod 34 contracts, causing the blocking plate 37 to block the pipe above again. The cooling will also allow the airbag 393 to return to normal. At this time, the backflow liquid can enter the guide pipe 391 through the sealing groove 392 for collection, avoiding sewage backflow.
[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, there are two sets of air guide grooves 38 symmetrically arranged about the axis of the air inlet pipe 32, and both sets of air guide grooves 38 are connected to the transmission pipe 33. Through the arrangement of the air guide grooves 38, when the blocking plate 37 descends, the generated gas can pass through the air guide grooves 38 to bypass the blocking plate 37, and release the high-temperature steam into the transmission pipe 33 for transmission.
[0027] In this embodiment, as Figure 1 , Figure 3 and Figure 5 As shown, the guide 39 includes a guide tube 391 and a collection chamber 394. One side of the guide tube 391 is connected to one side of the transmission pipe 33. A sealing groove 392 is provided in the inner wall of the guide tube 391, and an air bag 393 is inserted into the inner wall of the sealing groove 392. The end of the guide tube 391 extends to the outer wall of the device housing 1. The collection chamber 394 is fixed to the outer wall of the device housing 1. A collection box 395 is slidably arranged in the inner wall of the collection chamber 394. The collection box 395 is horizontally arranged with the extension end of the guide tube 391. Due to the temperature drop, the temperature of the air bag 393 drops and returns to normal, allowing the liquid to enter the guide tube 391 and be collected in the collection box 395 for storage, which is convenient for users to process.
[0028] In this embodiment, as Figure 1 and Figure 2 As shown, the evaporation chamber 2 includes a liquid storage tank 21 and an electric heating element 22. The bottom end of the liquid storage tank 21 is fixedly connected to the bottom wall of the evaporation chamber 2. An exhaust valve 23 is connected to the top wall of the liquid storage tank 21 and is connected to an inlet pipe 32. An inlet valve is connected to one side wall of the liquid storage tank 21. The side wall of the electric heating element 22 is fixed to the inner side wall of the evaporation chamber 2. The electric heating element 22 is electrically connected to the outer casing 1 of the device. By setting up several electric heating elements 22, the evaporation chamber is attempted to be heated at high temperature. 2. The waste liquid in the storage tank 21 is evaporated. The high temperature waste liquid vapor enters the gas pipe 32. At this time, the temperature of the entire evaporation chamber 2 rises, causing the temperature of the transmission chamber 31 above it to rise synchronously. At this time, the hydraulic oil inside the telescopic rod 34 in the gas inlet pipe 32 expands due to heat, causing the telescopic rod 34 to unfold. The push ring 35 moves down and at the same time, it drives the blocking plate 37 to move down, so that the high temperature steam can pass through the gas inlet pipe 32. At this time, the high temperature steam is transported to the cooling chamber 41 through the transmission pipe 33.
[0029] In this embodiment, as Figure 1 and Figure 2 As shown, there are several electric heating tubes 22, and these electric heating tubes 22 are horizontally distributed at equal intervals. Furthermore, there are two sets of electric heating tubes 22 symmetrically arranged about the axis of the evaporation chamber 2. By setting up these two sets of electric heating tubes 22, it is convenient to evaporate the waste liquid in the storage tank 21 at high temperature, so that the components that are easy to process can be taken out of the liquid through evaporation. The waste liquid components that have not reached the boiling point are retained in the storage tank 21 for separate processing.
[0030] In this embodiment, as Figure 1 and Figure 3As shown, the processing chamber 4 includes a cooling chamber 41. The outer wall of the cooling chamber 41 is fixedly connected to the inner wall of the processing chamber 4. A cooling pipe 42 is fixedly connected to the inner wall of the cooling chamber 41. The front end of the cooling pipe 42 is connected to the transmission pipe 33, and the end of the cooling pipe 42 is connected to the interior of the processing chamber 4. A large amount of high-temperature steam enters the cooling pipe 42. The high-temperature steam is extracted and cooled through the continuous cooling pipe 42 to avoid the high temperature from affecting the subsequent chemical reaction.
[0031] In this embodiment, as Figure 1 and Figure 3 As shown, the processing chamber 4 also includes a reaction tank 43. The bottom end of the reaction tank 43 is fixedly connected to the bottom wall of the processing chamber 4. A motor is fixed at the top of the reaction tank 43, and the main shaft of the motor extends into the inner wall of the reaction tank 43 and is fixedly connected to a rotating rod 44. The bottom end of the rotating rod 44 is rotatably connected to the bottom wall of the reaction tank 43. A sliding block 45 is sleeved on the outer wall of the rotating rod 44. A connecting rod 46 is rotatably connected to the rear end of the sliding block 45. A stirring cylinder 47 is rotatably connected to the end of the connecting rod 46 away from the sliding block 45. The shaft end of the stirring cylinder 47 is rotatably connected to the side wall of the processing chamber 4. The stirring cylinder 47 is hollow. A stirring plate 48 with a cross-shaped cross section is fixed in the inner wall of the stirring cylinder 47.
[0032] The top and side of the processing chamber 4 are respectively connected to a discharge valve and a reactant inlet / outlet valve. By starting the motor above the reaction tank 43, the motor drives the rotating rod 44 to rotate, which in turn drives the sliding block 45 to move up and down vertically. Through the up and down movement of the sliding block 45, the stirring cylinder 47 is driven to rotate continuously by the connecting rod 46. Furthermore, the stirring plate 48 inside the driving cylinder increases the agitation of the liquid and enhances the reaction effect.
[0033] In this embodiment, as Figure 1 and Figure 3 As shown, the outer wall of the rotating rod 44 has two threaded grooves with the same pitch and opposite directions, and the two ends are connected by transition curves. The two threaded grooves on the rotating rod 44 are threadedly engaged with the inner wall of the sliding block 45. Since the outer wall of the rotating rod 44 has two threaded grooves with the same pitch and opposite directions, and the two ends are connected by transition curves, the rotation of the rotating rod 44 can drive the sliding block 45 to move up and down on the rotating rod 44, so that the sliding block 45 can be driven to rotate through the connecting rod 46.
[0034] The method of use and advantages of this invention: The working process of this biomedical waste liquid treatment device is as follows:
[0035] like Figures 1 to 5As shown, by setting up several electric heating tubes 22, an attempt is made to heat the evaporation chamber 2 at high temperature to evaporate the waste liquid in the storage tank 21. The high-temperature waste liquid vapor enters the gas pipe 32. At this time, due to the temperature rise of the entire evaporation chamber 2, the temperature of the transmission chamber 31 above it rises synchronously. At this time, the hydraulic oil inside the telescopic rod 34 in the gas inlet pipe 32 expands due to heat, causing the telescopic rod 34 to unfold, pushing the ring sleeve 35 down and simultaneously driving the blocking plate 37 down, so that the high-temperature steam can pass through the gas inlet pipe 32. At this time, the high-temperature steam is transported to the cooling chamber 41 through the transmission pipe 33, and then enters the interior of the reaction tank 43 through the cooling pipe 42. Since chemical agents are added inside the reaction tank, they can chemically react with the output steam, converting a large amount of harmful substances into harmless substances. After treatment;
[0036] Simultaneously, the motor above the reaction vessel 43 can be started, and the motor drives the rotating rod 44 to rotate. Since the outer wall of the rotating rod 44 has two threaded grooves with the same pitch and opposite directions, and the two ends are connected by transition curves, the rotating rod 44 drives the sliding block 45 to move up and down in the vertical direction. Through the up and down movement of the sliding block 45, the connecting rod 46 drives the stirring drum 47 to rotate continuously. Furthermore, the stirring plate 48 inside the driving rod drum increases the stirring of the liquid and enhances the reaction effect.
[0037] Finally, when the equipment stops, the cooling pipe 42 cools down, producing a condensation effect. The residual gas condenses into water and flows back through the cooling pipe 42. At this time, due to the temperature drop, the telescopic rod 34 retracts, causing the blocking plate 37 to seal the air inlet pipe 32. However, at the same time, due to the temperature drop, the temperature of the airbag 393 decreases and returns to normal, allowing the liquid to enter the guide pipe 391 and be collected in the collection box 395 for storage, making it convenient for users to handle.
[0038] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
