During specific use, open the inlet cover and pour the waste liquid from the inlet 8 into the filter tank 6 of the waste liquid collection vehicle 1. At the initial position, the one-way filter box 80 is placed on the top of the filter tank 6, and the inlet 8 is connected It is placed at the lower end of the one-way filter box 80, so the entering waste liquid will not affect the one-way filter box 80. As the waste liquid increases, the waste liquid in the filter tank 6 will gradually rise, and then the drive motor will be turned on in the forward direction. 11;

The driving motor 11 drives the lifting screw 9 to rotate, and the lifting screw 9 drives the one-way filter box 80 to make the one-way filter box 80 move downward under the limit of the limit rod 29, so that the one-way filter box 80 squeezes the filter tank 6 The waste liquid and waste in the waste liquid (there is not only liquid in the waste liquid, but also waste, including common medical items such as cotton balls, gauze, cotton swabs), when the one-way filter box 80 squeezes the waste liquid and waste, the waste liquid Flow from the one-way valve 28 of the one-way filter box 80 to the top of the one-way filter box 80, due to the existence of the one-way valve 28, the waste liquid cannot flow back to the bottom of the one-way filter box 80 from the one-way valve 28, and then With the downward movement of the one-way filter box 80, the waste is gathered at the bottom of the filter tank 6, and the waste liquid is placed on the top of the one-way filter box 80. Since the waste is all soft items, the waste can be squeezed to the filter. At the bottom of the tank 6, a contact sensor is fixed below the filter tank 6 and close to the position below the output pipe 17. When the one-way filter box 80 touches the contact sensor, the water pump 18 starts to work, the first solenoid valve 36 is opened, and the drive motor 11 Stop, the sector gear meshes with the small one-way wheel 13 to rotate, and the small one-way wheel 13 drives the toggle lever 14 to stir the inching switch 16 of the disinfection box 15, so that the disinfectant releases the disinfectant in the filter tank 6, and the transmission wheel 25 passes through the filter tank 6. The first belt 24 drives the one-way pulley 23 to idle, and the sun gear 22 does not rotate. A flow sensor is installed at the output pipe 17/input pipe 19, and a liquid level sensor is installed in the filter tank 6. The flow sensor and the liquid level sensor are used together. , so that when the waste liquid in the filter tank 6 is pumped into the stirring tank 6, the water pump 18 stops working, the first solenoid valve 36 is closed, the driving motor 11 starts to reverse, the waste enters the slag discharge chamber 37, and the waste liquid enters the stirring tank 6 , the one-way filter box 80 reverses, the small one-way wheel 13 engaged with the sector gear rotates idly, does not drive the swing lever 14 to rotate, the transmission wheel 25 drives the one-way pulley 23 to rotate, the one-way pulley 23 drives the sun gear 22 to rotate, and the planetary pinion 21 rotates and revolves, the external gear 20 is fixed, and drives the disinfection disc 32 to rotate. In the initial position, the sealing baffle plate 34 seals the liquid discharge port 33, and the disinfection disc 34 is sleeved between the sun gear 22 and the one-way pulley 23 When the rotating shaft rotates, the disinfection plate 34 does not rotate, which is equivalent to a sleeve, so when the planetary pinion 21 rotates, the sealing baffle plate 34 will flow out of the disinfectant after breaking away from the liquid discharge port 33 to the stirring tank 7 , the liquid discharge port 33 is an intermittent liquid leakage, and the agitator 35 constantly stirs the waste liquid and the disinfectant in the stirring tank 7. When the drive motor 11 stops, in order to ensure that the sealing baffle plate 34 blocks the liquid discharge port 33, in a single A handle passing through the housing 4 is provided above the pulley 23, and the reverse rotation of the handle can make the sun gear 22 rotate, so that the planetary pinion 21 rotates to seal the liquid discharge port 33. In addition, it can be placed at the position of the stirring tank 7 The outer shell 4 is set as transparent, to observe whether the liquid discharge port 33 leaks, at the bottom of the filter tank 6 and the stirring tank 7, a cleaning plate 31 is installed to clean the bottom of the filter tank 6 and the stirring tank 7, in the bottom of the filter tank 6 and the stirring tank 7 sun gear 2 2, a time controller is installed below the sun gear 22 to set the time for rotation, for example, to be set to 5 minutes. After 5 minutes, the drive motor 11 stops, the second solenoid valve 42 is opened, and the second solenoid valve 42 and stirring A flow sensor and a depth sensor are respectively installed in the tank 7, and when the waste liquid in the stirring tank 7 flows out, the second electromagnetic valve 42 is closed.

The waste enters the slag discharge chamber 37 from the first electromagnetic valve 36. When the driving motor 11 rotates forward, the second pulley 59 drives the first pulley 57 to rotate, and the supporting screw 55 moves upward on the first pulley 57. When the driving motor 11 stops , the supporting screw 55 stops moving, and the supporting screw 55 is still in the second pulley 59 .

When the driving motor 11 reverses, the second pulley 59 drives the supporting screw 55 to move downward. When the external thread 56 of the supporting rod 53 matches the internal thread hole 54, it gradually cooperates with the supporting rod 53, and finally drives the supporting rod 53 to rotate. , the support rod 53 drives the right bevel gear 52 to rotate, and the left bevel gear 51 drives the incomplete gear 50 to rotate after changing direction. The waste liquid flows into the first heating chamber 38 from the liquid leakage plate 39 , the waste can enter the slag discharge chamber 37 from the outlet 47 , and finally the waste is cleaned out from the detachable liquid leakage plate 39 .

The waste liquid is sterilized here through high temperature in the first heating chamber 38 and the second heating chamber 41, and the water vapor produced by the high temperature is discharged into the shell 4 through the exhaust valve 44, and finally discharged through the exhaust fan 45 at the rear end of the shell 4.

The last thing to be explained in the present invention is that the time controller, flow sensor, liquid level sensor, and exhaust fan used are all connected to the battery, and the gears, pulleys, gear frames, rotating shafts, and incomplete gears are all connected by the required mounting plates, bolts, etc. The installation and connection of components is a usual installation method used by those skilled in the art.

The invention realizes the separation of waste liquid and waste through the one-way filter box in the filter tank, and performs primary disinfection, and fully mixes the waste liquid and disinfectant through the stirring tank for secondary disinfection, and waste can be removed from the slag discharge chamber, the first The heating chamber and the second heating chamber re-sterilize the waste liquid. The present invention has a good collection effect on the waste liquid, high collection efficiency, thorough disinfection, and can well ensure the safety of internal medicine nursing in waste liquid collection.
