Description

Technical Field

[0001] The invention relates to the technical field of medical waste treatment, in particular to a multi-stage sterilization system for medical waste. Background Art

[0002] With the development of my country's economy, my country's medical industry has made great progress, but many problems have also emerged, such as the treatment of medical waste. Medical waste treatment refers to the process by which relevant personnel deal with medical waste and garbage generated within the hospital that have physical, chemical or biological infectious hazards to humans, animals and the environment. It includes the process of properly disinfecting and even completely removing certain highly infectious medical waste.

[0003] A Chinese patent discloses a medical waste collection device with a patent application number of CN202010260898.1. A medical waste solid-liquid separation and collection device comprises a box body, a delivery port is provided at the upper part of the box body, and one side of the box body is connected to a solid waste collection box; a puncture assembly, the puncture assembly comprises two groups of rotating roller groups, and a plurality of groups of puncture needles are evenly installed on the rotating roller groups; two groups of compression assemblies, and the two groups of compression assemblies are arranged opposite to each other; a filter net, the filter net separates the lower part of the box body into a liquid waste collection box, and the filter net is obliquely installed at the lower part of the compression assembly; a suction assembly, and the suction assembly is slidably installed at the lower part of the filter net.

[0004] The comparative patent separates solid waste and liquid waste in medical waste through puncture components, compression components and suction components. However, there are some tough solid wastes containing liquid waste in the medical waste, which cannot be destroyed by a single puncture or extrusion, which also causes leakage during solid-liquid separation. In addition, the comparative patent only separates the solid and liquid of medical waste, and does not disinfect and sterilize it, which causes some volatile waste liquids to pollute the air, and may also cause waste to infect staff.

[0005] Therefore, a multi-stage sterilization system for medical waste is proposed. Summary of the invention

[0006] The object of the present invention is to provide a multi-stage sterilization system for medical waste to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a multi-stage sterilization system for medical waste, comprising a feed shell, a feed port, a discharge port, a feed motor and a spiral rotating shaft, wherein the feed port is provided at the upper end of the outer circumferential surface of the feed shell near one side edge; a feed motor is fixedly connected to the middle position of one end of the feed shell, and the output end of the feed motor passes through the outer surface of the feed shell and extends to the inside of the feed shell; the output end of the feed motor is fixedly connected to the spiral rotating shaft; a discharge port is provided at the lower end of the outer circumferential surface of the feed shell near the other side edge; a separation mechanism is fixedly connected to the lower end of the discharge port for solid-liquid separation of medical waste and separate them into solid and liquid, and treat them separately.

[0008] During operation, the comparative patent separates the solid waste and liquid waste in the medical waste through the puncture component, the compression component and the suction component. Some solid waste with strong toughness and containing liquid waste in the medical waste cannot be destroyed by a single puncture or extrusion, resulting in leakage during solid-liquid separation. In addition, the comparative patent only performs solid-liquid separation on the medical waste, and does not perform disinfection and sterilization, which may cause air pollution or infection of the staff. The present invention solves this problem by setting a separation mechanism, starts the feed motor, and the feed motor drives the spiral rotating shaft to start rotating. The medical waste enters the feed shell through the feed port, moves to the other end of the feed shell driven by the spiral rotating shaft, and finally enters the separation mechanism through the discharge port for solid-liquid separation, and performs disinfection and sterilization. The present invention can perform good solid-liquid separation on the medical waste and perform disinfection and sterilization by setting a separation mechanism, thereby avoiding the volatile liquid in the liquid waste from polluting the air and also avoiding the infection of the waste to the staff.

[0009] Preferably, the separation mechanism comprises a crushing shell, a crushing motor, a crushing shaft, a first conical disk, a second conical disk, a third conical disk, a hard filter, a crushing cone, a pressurizing mechanism, a connecting pipe, an electromagnetic door, a disinfection tank, a spray head, a discharge port, a stirring mechanism, a drain port and a neutralizer injection conduit; the lower end of the discharge port is fixedly connected to the crushing shell, and the crushing shell is L-shaped; the upper end of the inner circular surface of the crushing shell is fixedly connected to evenly distributed crushing cones; the middle position of the lower circular surface of the crushing shell is fixedly connected to the crushing motor; the output end of the crushing motor is fixedly connected to the crushing shaft, and one end of the crushing shaft passes through the lower circular surface of the crushing shell and extends to the interior thereof; the upper end of the outer circular surface of one end of the crushing shaft extending to the interior of the crushing shell is fixedly connected to the first conical disk, the second conical disk and the third conical disk from top to bottom, and the diameters of the first conical disk, the second conical disk and the third conical disk increase successively from top to bottom; a connecting pipe is fixedly connected to one side of the outer circular surface of the crushing shell, and one end of the connecting pipe passes through the side wall of the crushing shell; An electromagnetic door is provided between the connecting pipe and the crushing shell; an inclined hard filter is fixedly connected to the lower end of the surface of the inner cavity of the crushing shell near the lower edge of the interface with the connecting pipe, and the hard filter is penetrated by the crushing shaft; the other end of the connecting pipe is fixedly connected to the disinfection tank body, and the other end of the connecting pipe penetrates the side wall of the disinfection tank body; a conduit is fixedly connected to the middle position of the upper surface of the disinfection tank body, and one end of the conduit penetrates the upper surface of the disinfection tank body and extends to the interior thereof; a spray head is fixedly connected to the end of the conduit extending to the interior of the disinfection tank body; a discharge port is provided at a position on the inner surface of the disinfection tank body corresponding to the interface of the connecting pipe; a disinfection waste liquid treatment mechanism is fixedly installed at the lower end of the disinfection tank body; a neutralizer injection conduit is penetrated and connected to the upper surface of the transverse cavity of the crushing shell near the edge; a pressurizing mechanism is provided on the outer circumferential surface of the neutralizer injection conduit near the upper surface of the transverse cavity of the crushing shell; a stirring mechanism is provided at the middle position of the lower end of the inner surface of the transverse cavity of the crushing shell; a discharge port is provided at the lower end of the inner surface of the transverse cavity of the crushing shell near the edge.

[0010] During operation, in order to solve the problem that some solid waste with strong toughness and containing liquid waste inside medical waste is not easy to be destroyed for solid-liquid separation, and the solid waste and liquid waste obtained after solid-liquid separation of medical waste need to be disinfected and sterilized to prevent air pollution and infection of staff, the present invention sets a separation mechanism, starts the crushing motor, and the crushing motor drives the crushing shaft to rotate, drives the first cone disk, the second cone disk and the third cone disk to start rotating, and the waste enters the crushing shell through the discharge port, and is squeezed by the first cone disk, the second cone disk and the third cone disk. Waste of different sizes is squeezed by the crushing cone and crushed, and the crushed waste falls onto the hard filter screen, stands on the hard filter screen for a certain period of time, and the liquid waste passes through the holes on the hard filter screen. The liquid waste is dripped onto the lower surface of the inner cavity of the crushing shell, and the neutralizer is injected into the inner cavity of the crushing shell through the neutralizer injection conduit to neutralize the liquid waste. After the neutralization is completed, the drain port is opened to discharge the neutralized liquid waste; the electromagnetic door is opened, and the solid waste enters the disinfection tank through the connecting pipe. At this time, the disinfectant is injected and sprayed evenly on the solid waste through the spray head to disinfect and sterilize the liquid waste and bacterial microorganisms remaining on the solid waste, and finally the discharge port is opened to take out the disinfected solid waste; the present invention sets a separation mechanism, a first cone disk, a second cone disk, a third cone disk and a crushing cone to perform solid-liquid separation on medical waste, and then neutralizes the separated liquid and disinfects the separated solid, thereby preventing the waste liquid from volatilizing into the air to pollute the air and prevent infection of the staff.

[0011] Preferably, the disinfection waste liquid treatment mechanism includes a treatment tank body, an elastic filter screen, a flipping mechanism and a shaking mechanism; the treatment tank body is fixedly installed at the lower end of the disinfection tank body, and a mounting port is provided at the connection between the treatment tank body and the lower surface of the disinfection tank body; an elastic filter screen is fixedly installed in the mounting port; the left side of the outer surface of the treatment tank body is the same as the horizontal cavity of the crushing shell; a flipping mechanism is arranged in the middle position of the lower surface of the treatment tank body; a shaking mechanism is arranged on the lower surface of the elastic filter screen near the flipping mechanism.

[0012] During operation, when solid waste is disinfected and sterilized in the disinfection tank, it is impossible to determine the amount of liquid waste remaining on the solid waste, and thus it is impossible to quantitatively spray disinfectant on the solid waste, which may result in excessive spraying of disinfectant, resulting in a waste of disinfectant, or insufficient spraying of disinfectant, resulting in a small amount of liquid waste remaining on the solid waste. The present invention provides a disinfection waste liquid treatment mechanism, and continuously sprays disinfectant on the disinfection tank through a spray head. The sprayed excess disinfectant will enter the treatment tank through an elastic filter screen, and the treatment tank and the broken The present invention is the same as the crushing shell, the excess disinfectant flows into the horizontal cavity with the crushing shell through the processing tank body, and is mixed with the liquid waste to disinfect the liquid mixture, and the neutralizer is injected into the mixed liquid through the neutralizer injection conduit; by arranging a disinfection waste liquid treatment mechanism, the disinfectant is continuously injected by the spray head, and the excess disinfectant enters the horizontal cavity of the crushing shell through the processing tank body and is mixed with the liquid waste, and then is neutralized by the neutralizer, thereby avoiding the phenomenon of excessive or insufficient disinfectant, and preventing air pollution and infection of staff.

[0013] Preferably, the flipping mechanism includes a flipping motor, a flipping shaft and a flipping rod; the flipping motor is fixedly connected to the middle position of the lower surface of the processing tank body; the output end of the flipping motor is fixedly connected to the flipping shaft, and one end of the flipping shaft passes through the lower surface of the processing tank body to extend into the interior thereof and passes through the elastic filter to extend into the interior of the disinfection tank body; the outer circular surface of one end of the flipping shaft extending into the interior of the disinfection tank body is fixedly connected to symmetrically and evenly distributed flipping rods.

[0014] During operation, when there are a lot of solid wastes piled up in the disinfection tank, a certain solid waste may safely cover another smaller solid waste, and there is a lot of liquid waste remaining on the smaller solid waste. At this time, the disinfectant cannot disinfect and sterilize the smaller solid waste, resulting in missing disinfection. The present invention sets a flip mechanism, starts a flip motor, and the flip motor drives the flip shaft to rotate, drives the flip rod to rotate, and the rotation of the flip rod drives the solid waste to rotate and flip together, so that the disinfectant can be sprayed on each solid waste for disinfection and sterilization. The present invention sets a flip mechanism, and the flip rod rotates in the disinfection tank to flip the solid waste, thereby preventing the missing disinfection caused by larger solid waste covering smaller solid waste.

[0015] Preferably, the shaking mechanism includes a shifting block and a cross bar; two shaking shifting blocks are symmetrically fixedly connected to the lower surface of the elastic filter near the flip rod; and two cross bars are symmetrically fixedly connected to the outer circular surface of the flip rod near the elastic filter.

[0016] During operation, when the turning rod rotates in the disinfection tank body to turn the solid waste, there may always be small liquid waste water droplets and disinfectant water droplets on the surface of some solid waste, which cannot drip off, so that there is still a chance of air pollution and infection of the staff; the present invention sets a shaking mechanism, and when the turning shaft rotates, the cross bar is driven to rotate. When the cross bar rotates to contact with the shift block, the cross bar is still driven by the turning shaft to rotate forward and slide over the inclined surface of the shift block. During this process, the elastic filter screen will generate an up and down shake, driving the solid waste above the elastic filter screen to shake, thereby shaking off the liquid waste water droplets and disinfectant water droplets on the surface of the solid waste; the present invention sets a shaking mechanism to shake off the liquid waste water droplets and disinfectant water droplets attached to the surface of the solid waste, prevent these water droplets from contacting with the air and the staff, and reduce the chance of air pollution and infection of the staff.

[0017] Preferably, the pressurizing mechanism includes a pressurizing shell, an air hole, a pressing rod, a movable plate, a cavity plate, a one-way valve and a spring; the pressurizing shell is arranged on the outer circular surface of the neutralizer injection conduit near the upper surface of the transverse cavity of the crushing shell; an air hole is provided on the upper side surface of the pressurizing shell near the edge; a pressing rod is arranged in the middle position of the upper surface of the pressurizing shell, and one end of the pressing rod penetrates the upper surface of the pressurizing shell and extends to the interior thereof; one end of the pressing rod extending to the interior of the pressurizing shell is fixedly connected to the movable plate; a conduit is fixedly connected to the lower surface of the pressurizing shell, and one end of the conduit penetrates the lower surface of the pressurizing shell; the other end of the conduit is fixedly connected to the upper surface of the transverse cavity of the crushing shell near the edge, and the other end of the conduit penetrates the upper surface of the transverse cavity of the crushing shell and extends to the interior thereof where it is fixedly connected to the cavity plate.

[0018] During operation, the neutralizer is injected into the transverse cavity of the crushing shell through the neutralizer injection conduit. The injection speed may be too slow, resulting in the required amount of neutralizer being delayed in the transverse cavity of the crushing shell, so that the neutralizer does not have enough time to react with the mixed liquid of liquid waste and disinfectant, thereby affecting the neutralization efficiency. The present invention provides a pressurizing mechanism to inject the neutralizer into the pressurized shell in the pressurizing mechanism from the neutralizer injection conduit. The one-way valve can prevent the neutralizer from flowing back. The pressing rod is pressed, and air enters the pressurized shell from the air hole, so that the pressing is not affected. Through pressing with different intensities, the neutralizer enters the cavity plate through the conduit, and flows out from the small holes evenly distributed on the lower surface of the cavity plate at different speeds. The present invention can timely add a sufficient amount of neutralizer to the transverse cavity of the crushing shell by providing a pressurizing mechanism, and can control the outflow speed of the neutralizer by adjusting the pressing force on the pressing rod, thereby adapting to the different reaction times and neutralizer dosages required for different liquid wastes.

[0019] Preferably, two springs are symmetrically fixedly connected to the upper surface of the movable plate, and one end of each spring is fixedly connected to the upper surface of the inner cavity of the pressurized shell.

[0020] During operation, when the neutralizer inside the pressurized shell is completely discharged into the transverse cavity of the crushing shell by pressing the pressing rod, the pressing rod needs to be pulled upward to allow the neutralizer to be injected into the bottom of the movable plate through the neutralizer injection conduit, thereby continuing to pressurize and inject the neutralizer into the transverse cavity of the crushing shell; the present invention arranges a spring, and when no pressing force is provided to the pressing rod, the spring is in a normal state, and when pressing force is applied to the pressing rod, the spring is stretched, and when the pressing force is withdrawn, the spring contracts and drives the movable plate to move upward; the present invention arranges a spring, so that the pressing rod can be pulled back to its original position after being pressed, thereby providing space for the neutralizer to be injected into the pressurized shell, saving the physical strength consumed by the staff in pulling back the pressing rod until the bottom of the movable plate is filled with the neutralizer.

[0021] Preferably, the stirring mechanism includes a stirring shaft and a stirring rod; a stirring shaft is fixedly connected to the middle position of the lower surface of the horizontal cavity of the crushing shell, and one end of the stirring shaft penetrates the lower surface of the horizontal cavity of the crushing shell and extends into the interior thereof; the outer circular surface of one end of the stirring shaft extending into the interior of the crushing shell is fixedly connected to stirring rods that are symmetrically and evenly distributed; the other end of the stirring shaft is rotatably connected to the flip shaft through a pulley.

[0022] During operation, since the properties and densities of different liquid wastes are different from those of the neutralizer and disinfectant, slow neutralization may occur due to the difference in properties and densities. The present invention sets a stirring mechanism and starts a flip motor, which drives the flip shaft to rotate, and drives the stirring shaft to rotate through a pulley, thereby driving the stirring rod to rotate. The stirring rod rotates in the liquid waste, neutralizer and disinfectant. The present invention sets a stirring mechanism and rotates the stirring rod to fully mix the liquid waste, neutralizer and disinfectant, accelerate the neutralization reaction of the three, and improve the neutralization efficiency of the neutralizer.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] The present invention can perform good solid-liquid separation treatment on medical waste by arranging a separation mechanism, including crushing some solid waste with strong toughness and containing liquid waste in the medical waste, and realize solid-liquid separation operation. At the same time, by using a disinfectant to disinfect and sterilize the solid waste and using a neutralizer to neutralize the liquid waste, it can prevent the liquid waste from causing air pollution and also prevent the liquid waste remaining on the solid waste from infecting the staff.

[0043] During operation, when the solid waste is disinfected and sterilized in the disinfection tank 612, it is impossible to determine the amount of liquid waste remaining on the solid waste, and it is also impossible to spray the solid waste with a quantitative amount of disinfectant, which may result in excessive spraying of the disinfectant, resulting in a waste of the disinfectant, or insufficient spraying of the disinfectant, resulting in a small amount of liquid waste remaining on the solid waste.

[0045] During operation, when there are a lot of solid wastes piled up in the disinfection tank 612, it is possible that one solid waste may safely cover another smaller solid waste, and there is a lot of liquid waste remaining on the smaller solid waste. At this time, the disinfectant cannot disinfect and sterilize the smaller solid waste, resulting in missing disinfection. The present invention sets a flip mechanism 73, starts the flip motor 731, and the flip motor 731 drives the flip shaft 732 to rotate, drives the flip rod 733 to rotate, and the rotation of the flip rod 733 drives the solid waste to rotate and flip together, so that the disinfectant can be sprayed on each solid waste for disinfection and sterilization. The present invention sets a flip mechanism 73, and the flip rod 733 rotates in the disinfection tank 612 to flip the solid waste, thereby preventing the missing disinfection caused by larger solid waste covering smaller solid waste.

[0046] As an embodiment of the present invention, Figure 6 As shown, the shaking mechanism 74 includes a shift block 741 and a cross bar 742; two shaking shift blocks 741 are symmetrically fixedly connected to the lower surface of the elastic filter 72 near the flip rod 733; and two cross bars 742 are symmetrically fixedly connected to the outer circumferential surface of the flip rod 733 near the elastic filter 72.

[0047] During operation, when the flip rod 733 rotates in the disinfection tank body 612 to flip the solid waste, there may always be small liquid waste water droplets and disinfectant water droplets on the surface of some solid waste, which cannot drip off, so that there is still a chance of air pollution and infection of the staff; the present invention sets a shaking mechanism 74, and when the flip shaft 732 rotates, it drives the cross bar 742 to rotate. When the cross bar 742 rotates to contact with the dial block 741, the cross bar 742 is still rotating forward driven by the flip shaft 732, sliding over the inclined surface of the dial block 741. During this process, the elastic filter screen 72 will generate an up and down shake, driving the solid waste above the elastic filter screen 72 to shake, thereby shaking off the liquid waste water droplets and disinfectant water droplets on the surface of the solid waste; the present invention sets a shaking mechanism 74 to shake off the liquid waste water droplets and disinfectant water droplets attached to the surface of the solid waste, prevent these water droplets from contacting with the air and the staff, and reduce the chance of air pollution and infection of the staff.

[0048] As an embodiment of the present invention, Figure 7 As shown, the pressurizing mechanism 69 includes a pressurizing shell 691, an air hole 692, a pressing rod 693, a movable plate 694, a cavity plate 695, a one-way valve 696 and a spring 697; the pressurizing shell 691 is arranged on the outer circumference of the neutralizing agent injection conduit 617 near the upper surface of the transverse cavity of the crushing shell 61; the upper side surface of the pressurizing shell 691 is provided with an air hole 692 near the edge; a pressing rod 693 is arranged in the middle of the upper surface of the pressurizing shell 691, and one end of the pressing rod 693 penetrates It passes through the upper surface of the pressurized shell 691 and extends into the interior thereof; one end of the pressing rod 693 extending into the interior of the pressurized shell 691 is fixedly connected to a movable plate 694; a conduit is fixedly connected to the lower surface of the pressurized shell 691, and one end of the conduit passes through the lower surface of the pressurized shell 691; the other end of the conduit is fixedly connected to the upper surface of the transverse cavity of the crushing shell 61 near the edge, and the other end of the conduit passes through the upper surface of the transverse cavity of the crushing shell 61 and extends into the interior thereof and is fixedly connected to a cavity plate 695.

[0049] During operation, the neutralizer injection conduit 617 injects the neutralizer into the transverse cavity of the crushing shell 61. The injection speed may be too slow, resulting in the required amount of neutralizer not being obtained in the transverse cavity of the crushing shell 61, so that the neutralizer does not have enough time to react with the mixed liquid of liquid waste and disinfectant, thereby affecting the neutralization efficiency. The present invention provides a pressurizing mechanism 69, and injects the neutralizer from the neutralizer injection conduit 617 into the pressurizing shell 691 in the pressurizing mechanism 69. The one-way valve 696 can prevent the neutralizer from flowing back, and the pressing rod 693 is pressed. The air enters the pressurized shell 691 from the air hole 692, so as not to affect the pressing. By pressing with different intensities, the neutralizer enters the cavity plate 695 through the conduit, and flows out from the small holes evenly distributed on the lower surface of the cavity plate 695 at different speeds. The present invention can add a sufficient amount of neutralizer to the transverse cavity of the crushing shell 61 in time by setting a pressurizing mechanism 69, and can control the speed at which the neutralizer flows out by adjusting the pressing force on the pressing rod 693, thereby adapting to the different reaction times and amounts of neutralizer required for different liquid wastes.

[0050] As an embodiment of the present invention, Figure 7 As shown, two springs 697 are symmetrically fixedly connected to the upper surface of the movable plate 694 , and one end of each spring 697 is fixedly connected to the upper surface of the inner cavity of the pressurized shell 691 .

[0051] During operation, when the neutralizer inside the pressurized shell 691 is completely discharged into the transverse cavity of the crushing shell 61 by pressing the pressing rod 693, the pressing rod 693 needs to be pulled upward to allow the neutralizer to be injected into the bottom of the movable plate 694 through the neutralizer injection conduit 617, thereby continuing to pressurize and inject the neutralizer into the transverse cavity of the crushing shell 61; the present invention sets a spring 697, and when no pressing force is applied to the pressing rod 693, the spring 697 is in a normal state, and when pressing force is applied to the pressing rod 693, the spring 697 is stretched, and when the pressing force is withdrawn, the spring 697 contracts and drives the movable plate 694 to move upward; the present invention sets a spring 697, so that the pressing rod 693 can be pulled back to its original position after being pressed, thereby providing space for the neutralizer to be injected into the pressurized shell 691, saving the physical strength consumed by the staff in pulling back the pressing rod 693 until the bottom of the movable plate 694 is filled with the neutralizer.

[0052] As an embodiment of the present invention, Figure 8As shown, the stirring mechanism 615 includes a stirring shaft 6151 and a stirring rod 6152; the stirring shaft 6151 is fixedly connected to the middle position of the lower surface of the horizontal cavity of the crushing shell 61, and one end of the stirring shaft 6151 penetrates the lower surface of the horizontal cavity of the crushing shell 61 and extends to the interior thereof; the outer circular surface of one end of the stirring shaft 6151 extending to the interior of the crushing shell 61 is fixedly connected to the stirring rod 6152 which is symmetrically and evenly distributed; the other end of the stirring shaft 6151 is rotatably connected to the flip shaft 732 via a pulley.

[0053] During operation, since the properties and densities of different liquid wastes are different from those of the neutralizer and disinfectant, slow neutralization may occur due to the difference in properties and densities. The present invention sets a stirring mechanism 615 to start the flip motor 731. The flip motor 731 drives the flip shaft 732 to rotate, and drives the stirring shaft 6151 to rotate through the pulley, thereby driving the stirring rod 6152 to rotate. The stirring rod 6152 rotates in the liquid waste, neutralizer and disinfectant. The present invention sets a stirring mechanism 615 to rotate the stirring rod 6152, so that the liquid waste, neutralizer and disinfectant are fully mixed, the neutralization reaction of the three is accelerated, and the neutralization efficiency of the neutralizer is improved.

[0054] Method of use: When the present invention is used, first start the feed motor 4, the feed motor 4 drives the spiral rotating shaft 5 to start rotating, the medical waste enters the feed shell 1 through the feed port 2, moves to the other end of the feed shell 1 driven by the spiral rotating shaft 5, and finally enters the separation mechanism 6 through the discharge port 3 for solid-liquid separation; start the flat crushing motor 62, the crushing motor 62 drives the crushing shaft 63 to rotate, drives the first cone disk 64, the second cone disk 65 and the third cone disk 66 to start rotating, the waste enters the crushing shell 61 through the discharge port 3, and is squeezed by the first cone disk 64, the second cone disk 65 and the third cone disk 66, and the waste of different volumes is separated. Small wastes are squeezed and crushed by the crushing cone 68. The crushed wastes fall onto the hard filter screen 67 and stand on the hard filter screen 67 for a certain period of time. Liquid wastes drip onto the lower surface of the inner cavity of the crushing shell 61 through the holes on the hard filter screen 67. The neutralizer is injected into the inner cavity of the crushing shell 61 by the neutralizer injection conduit 617 to neutralize the liquid wastes. After the neutralization is completed, the drain port 616 is opened to discharge the neutralized liquid wastes. The electromagnetic door 611 is opened, and the solid wastes enter the disinfection tank 612 through the connecting pipe 610. At this time, the disinfectant is injected, and the disinfectant is continuously sprayed into the disinfection tank 612 through the spray head 613 to neutralize the solid wastes. The liquid waste and bacterial microorganisms remaining on the surface are disinfected and sterilized, the flip motor 731 is started, the flip motor 731 drives the flip shaft 732 to rotate, drives the flip rod 733 to rotate, and the rotation of the flip rod 733 drives the solid waste to rotate and flip together, so that the disinfectant can be sprayed on each solid waste for disinfection and sterilization. When the flip shaft 732 rotates, it drives the cross bar 742 to rotate. When the cross bar 742 rotates to contact the dial block 741, the cross bar 742 is still rotating forward driven by the flip shaft 732 and slides over the inclined surface of the dial block 741. In this process, the elastic filter screen 72 will produce an up and down shake, driving the solid waste above the elastic filter screen 72 to shake. The solid waste is shaken off by the action of the discharge port 614, and the solid waste after disinfection is taken out. The sprayed excess disinfectant will enter the processing tank body 71 through the elastic filter screen 72. The processing tank body 71 is the same as the crushing shell 61. The excess disinfectant flows into the transverse cavity with the crushing shell 61 through the processing tank body 71 and mixes with the liquid waste to disinfect the liquid mixture. The neutralizer is injected from the neutralizer injection conduit 617 to neutralize the mixed liquid. The neutralizer is injected from the neutralizer injection conduit 617 into the pressurizing shell 691 in the pressurizing mechanism 69, and the one-way valve 696 can prevent the neutralizer from flowing back.When the pressing rod 693 is pressed, air enters the pressurized housing 691 from the air hole 692, so that the pressing is not affected. By pressing with different strengths, the neutralizer enters the cavity plate 695 through the conduit and flows out from the small holes evenly distributed on the lower surface of the cavity plate 695 at different speeds. When no pressing force is applied to the pressing rod 693, the spring 697 is in a normal state. When the pressing force is applied to the pressing rod 693, the spring 697 is stretched. When the pressing force is withdrawn, the spring 697 contracts and drives the movable plate 694 to move upward. The flip motor 731 drives the flip shaft 732 to rotate, and drives the stirring shaft 6151 to rotate through the pulley, thereby driving the stirring rod 6152 to rotate. The stirring rod 6152 rotates in the liquid waste, the neutralizer and the disinfectant, so that the liquid waste, the neutralizer and the disinfectant are fully mixed, the neutralization reaction of the three is accelerated, and the neutralization efficiency of the neutralizer is improved. ;
