[0017] Step 4: Finally, when the first processing chamber rotates to the rear side of the second mounting slot and the top is exposed, the cleaning liquid and water are transported to the inside of the purification tank inside the first processing chamber through the cleaning pipe, and then the second motor is started to drive the rotating shaft to rotate, and the first electric push rod and the push plate rotate to make the stirring rod stir, and the first electric push rod is started to make the push plate move back and forth to knock the filter screen to remove the impurities remaining on the filter screen and clean the inside of the purification tank.

[0019] (1) The present invention can rotate the first processing chamber and the second processing chamber by rotating the processing tank. When the first processing chamber has just finished processing the waste liquid, the second processing chamber can continue to process the waste liquid by switching the first processing chamber and the second processing chamber. At the same time, the first processing chamber can also be cleaned, so that the first processing chamber or the second processing chamber after the waste liquid is processed can be cleaned in time, and the waste liquid can be continuously processed and purified, so as to improve the work efficiency.

[0020] (2) The present invention can install and replace the activated carbon plate, which is convenient for adsorbing the odor generated by the reaction of waste liquid with reagents during treatment. At the same time, it can limit the sealing cover and the baffle to improve the sealing performance of the sealing cover and prevent leakage of waste liquid, thereby facilitating use.

At this time, the sealing cover 19 is located at the top of the second processing chamber, and the first connecting pipe 11 outside the first processing chamber is opened. 4 and the second connecting pipe 15 are rotated to the rear side of the third installation slot, and the second connecting pipe 15 is connected to the collecting pipe 16 through the connecting structure 18. The first connecting pipe 14 and the second connecting pipe 15 outside the second processing chamber are rotated to the front side of the third installation slot, and are respectively connected to the water inlet pipe 4 and the water outlet pipe 5 through the connecting structure 18. The waste liquid is transported to the inside of the second processing chamber by the water inlet pipe 4 and the first connecting pipe 14, and the waste liquid is continuously purified. At the same time, when the first processing chamber is rotated to the rear side of the third installation slot, the cleaning liquid and water are transported to the inside of the purification tank inside the first processing chamber through the cleaning pipe 24, and the stirring structure inside the first processing chamber is started to rotate, and the filter screen 13 is knocked to remove the impurities remaining on the filter screen 13, and the inside of the purification tank is cleaned. The cleaned liquid is transported to the inside of the conveying tank through the conveying pipe 11, and is collected by the collecting pipe 16 to the inside of the waste water tank 17 for collection, and then the collecting structure 25 is started for collection, which is convenient for treating the waste liquid and cleaning the first processing chamber at the same time, so as to improve the work efficiency.

When the third motor 251 drives the threaded rod 252 to rotate, since the top of the moving block 253 is movably connected with the top of the second mounting groove, the moving block 253 can drive the collecting box 255, the collecting pump and the suction tube to move back and forth on the threaded rod 252. The second electric push rod 30 is fixed by the support plate 254. When the second electric push rod 30 is started to drive the connecting plate 31 to move, the moving plate 35 drives the suction tube to extend downward, so that the impurities remaining in the fixed groove can be removed, and the impurities remaining in the first processing chamber or the second processing chamber can be sucked and collected through the collecting box 255, so as to improve the reuse of the first processing chamber or the second processing chamber after cleaning.

[0046] like Figure 6 , Figure 8 , Fig. 9As shown, a placement groove is opened inside the sealing cover 19 near one end of the baffle 9, a mounting block 32 is arranged inside the sealing cover 19, an activated carbon plate 33 is arranged in the middle of the mounting block 32, the activated carbon plate 33 is located at the top of the purification tank, a fixed spring 34 is fixedly connected to one side of the mounting block 32, one end of the fixed spring 34 is fixedly connected to the inner wall of the placement groove, movable plates 35 are arranged at both ends of the mounting block 32 and on both sides of the connecting spring, a pulling block 36 is fixedly connected to the side of the mounting block 32 away from the connecting spring, and sockets are opened at both ends of the top of the baffle 9, and a limiting hole is arranged in the middle of the socket.

[0047] Pulling the pull block 36 allows the mounting block 32 to move out of the interior of the sealing cover 19. The movement of the mounting block 32 causes the fixed spring 34 to stretch, thereby driving the movable plate 35 to move toward the middle of the mounting block 32, and then placing the activated carbon plate 33 in the middle of the mounting block 32, so as to facilitate the replacement of the activated carbon plate 33. By loosening the pull block 36, the mounting block 32 moves to its original position under the action of the fixed spring 34. The activated carbon plate 33 is located at the bottom of the sealing cover 19 and at the top of the first processing chamber. The activated carbon plate is used for adsorption to remove the odor generated when the reagent reacts with the waste liquid, thereby improving the waste liquid treatment effect.

[0048] like Figures 9 to 11 As shown, the movable plate 35 is located inside the placement groove, and the bottom end of the movable plate 35 is an inclined surface.

One end of the connecting spring is fixedly connected to the bottom of the limit block 40, and the other end passes through the bottom of the sealing cover 19 and is fixedly connected to the inner wall of the limit hole. The plug rod 39 passes through the sealing cover 19 and is plugged into the jack, and the limit block 40 passes through the sealing cover 19 and is plugged into the limit hole.

[0049] When the mounting block 32 moves to the outside of the sealing cover 19, the mounting block 32 drives the movable plate 35 to move, so that the round protrusion 37 at the bottom of the movable plate 35 moves along the inclined surface, and under the action of the connecting spring, the round protrusion 37 drives the limit block 40, the insertion rod 39 and the limit block 40 to move upward, so that the insertion rod 39 is separated from the insertion hole, and the limit block 40 is separated from the limiting hole, and the sealing cover 19 is no longer limited.

[0050] The present invention also provides a method for using the above-mentioned waste liquid treatment equipment of the hospital laboratory, which comprises the following steps:

[0051] Step 1: First, open the protective door 3, pull the pull block 36 to move the mounting block 32 out of the interior of the sealing cover 19, the movement of the mounting block 32 causes the fixed spring 34 to stretch, the movable plate 35 moves toward the middle of the mounting block 32, and the convex 37 moves along the inclined surface. Under the action of the connecting spring, the convex 37 drives the limit block 40, the plug rod 39 and the limit block 40 to move upward, so that the plug rod 39 is separated from the insertion hole, and the limit block 40 is separated from the limiting hole, and the sealing cover 19 is no longer limited. Then put the activated carbon plate 33 into the middle of the mounting block 32, and by loosening the pull block 36, under the action of the fixed spring 34, the mounting block 32 moves to its original position, the activated carbon plate 33 is located at the bottom of the sealing cover 19 and at the top of the first processing chamber, and at the same time, the fixed plate 20 moves to the inside of the placement groove, and the convex 37 moves to its original position. Through the action of the connecting spring, the plug rod 39 is plugged into the insertion hole, and the limit block 40 is plugged into the limiting hole, so as to limit the sealing cover 19;

[0052] Step 2: The waste liquid is transported to the interior of the purification tank through the water inlet pipe 4 and the first connecting pipe 14, and the waste liquid is filtered through the filter screen 13. The impurities and particles after filtration fall into the collecting tank 26 for collection, and the filtered waste liquid is transported to the interior of the purification tank. The second solenoid valve is controlled by the controller 2 to transport the reagent in the reagent bottle 22 to the interior of the purification tank to purify the waste liquid. At the same time, the third motor 271 is started to drive the rotating shaft 272 to rotate, so that the first electric push rod 273 drives the push plate 274 to rotate, and the waste liquid and the reagent are fully mixed by the rotation of the stirring rod 275 to increase the purification effect;

[0053] Step 3: Then, the activated carbon plate 33 at the bottom of the sealing cover 19 is used for adsorption to remove the odor generated when the reagent reacts with the waste liquid. After the treatment is completed, the treated waste liquid is transported to the inside of the conveying tank through the conveying pipe 11 by opening the first solenoid valve 12, and then discharged through the outlet pipe 5. When the treatment of the first treatment chamber is completed, the first motor 7 is started again, so that the first motor 7 drives the rotating rod 8 and the treatment tank 6 to rotate, and the movable rod 28 at the bottom of the sealing cover 19 slides inside the annular groove 29 at the top of the treatment tank 6, so that the first treatment chamber rotates to the rear side of the third installation groove, and the second treatment chamber rotates to the front side of the third installation groove. The first connecting pipe 14 and the second connecting pipe 15 outside the first treatment chamber rotate to the rear side of the third installation groove, and the second connecting pipe 15 is connected to the collecting pipe 16 through the connecting structure 18. The first connecting pipe 14 and the second connecting pipe 15 outside the second treatment chamber rotate to the front side of the third installation groove, and are respectively connected to the water inlet pipe 4 and the water outlet pipe 5 through the connecting structure 18, and the waste liquid continues to be purified through the second treatment chamber;

[0054] Step 4: Finally, when the first processing chamber rotates to the rear side of the second installation slot and the top is exposed, the cleaning liquid and water are transported to the inside of the purification tank inside the first processing chamber through the cleaning pipe 24, and then the third motor 271 is started to drive the rotating shaft 272 to rotate, and the first electric push rod 273 and the push plate 274 are rotated, so that the stirring rod 275 is stirred, and the first electric push rod 273 is started to make the push plate 274 move back and forth, the filter screen 13 is knocked, the impurities remaining on the filter screen 13 are removed, and the inside of the purification tank is cleaned, and the cleaned liquid is transported to the inside of the conveying tank through the conveying pipe 11, and collected by the collecting pipe 16 to the inside of the wastewater tank 17 for collection, and then the collecting pump and the second electric push rod 30 are started to move the suction pipe to the inside of the purification tank, and at the same time, the third motor 251 is started to drive the threaded rod 252 to rotate, so that the moving block 253 drives the collecting box 255 to move back and forth at the top of the first processing chamber, and the impurities remaining in the suction are collected through the collecting box 255, which is convenient for the treatment of waste liquid and the cleaning of the first processing chamber.

[0055] Working principle: when in use, the protective door 3 is opened, and the pulling block 36 is pulled to make the mounting block 32 move out of the interior of the sealing cover 19. The movement of the mounting block 32 causes the fixing spring 34 to stretch, and the movable plate 35 moves toward the middle of the mounting block 32. The round protrusion 37 moves along the inclined surface. Under the action of the connecting spring, the round protrusion 37 drives the limiting block 40, the insertion rod 39 and the limiting block 40 to move upward, so that the insertion rod 39 is separated from the insertion hole, and the limiting block 40 is separated from the limiting hole, and the sealing cover 19 is no longer limited. Then the activated carbon plate 33 is placed in the middle of the mounting block 32, and by loosening the pulling block 36, under the action of the fixing spring 34, the mounting block 32 moves to its original position, and the activated carbon plate 33 is located at the bottom of the sealing cover 19 and at the top of the first processing chamber. At the same time, the fixing plate 20 moves to the inside of the placement groove, and the round protrusion 37 moves to its original position. Through the action of the connecting spring, the insertion rod 39 is plugged into the insertion hole, and the limiting block 40 is plugged into the limiting hole. The sealing cover 19 is limited, and the waste liquid is transported to the interior of the purification tank through the water inlet pipe 4 and the first connecting pipe 14, and the waste liquid is filtered through the filter net 13. The impurities and particles after filtration fall into the collecting tank 26 for collection, and the filtered waste liquid is transported to the interior of the purification tank. The controller 2 controls the second solenoid valve to transport the reagent in the reagent bottle 22 to the interior of the purification tank to purify the waste liquid. At the same time, the third motor 271 is started to drive the rotating shaft 272 to rotate, so that the first electric push rod 273 drives the push plate 274 to rotate, and the waste liquid and the reagent are fully mixed by the rotation of the stirring rod 275, and then the activated carbon plate 33 at the bottom of the sealing cover 19 is used for adsorption to remove the odor generated when the reagent and the waste liquid react. After the treatment is completed, the treated waste liquid is transported to the interior of the conveying tank through the conveying pipe 11 by opening the first solenoid valve 12, and then discharged through the water outlet pipe 5.

[0056] When the processing of the first processing chamber is completed, the first motor 7 is started again, so that the first motor 7 drives the rotating rod 8 and the processing tank 6 to rotate, and the movable rod 28 at the bottom of the sealing cover 19 slides inside the annular groove 29 at the top of the processing tank 6, so that the first processing chamber rotates to the rear side of the third installation groove, and the second processing chamber rotates to the front side of the third installation groove. The first connecting pipe 14 and the second connecting pipe 15 outside the first processing chamber rotate to the rear side of the third installation groove, and the second connecting pipe 15 is connected to the collecting pipe 16 through the connecting structure 18. The first connecting pipe 14 and the second connecting pipe 15 outside the second processing chamber rotate to the front side of the third installation groove, and are respectively connected to the water inlet pipe 4 and the water outlet pipe 5 through the connecting structure 18, and the waste liquid continues to be purified through the second processing chamber. When the first processing chamber rotates to the rear side of the second installation groove and the top is exposed, the cleaning liquid and water are transported to the inside of the first processing chamber through the cleaning pipe 24 The interior of the purification tank is moved to the inside of the purification tank, and the third motor 271 is started to drive the rotating shaft 272 to rotate, and the first electric push rod 273 and the pushing plate 274 are rotated to make the stirring rod 275 stir, and the first electric push rod 273 is started to make the pushing plate 274 move back and forth, and the filter screen 13 is knocked to remove the impurities remaining on the filter screen 13, and the interior of the purification tank is cleaned.
