Description

Technical Field

[0001] The present application relates to the technical field, and in particular to a cow dung solid-liquid separation device with a sterilization function. Background Art

[0002] At present, with the continuous development of animal husbandry and other breeding industries, the scale of cattle farms continues to expand. While providing a large amount of beef, cattle farms also produce a large amount of cow dung. Therefore, solid-liquid separation of cow dung in cattle farms is an important link. Cow dung that has undergone solid-liquid separation can be used as an important resource in fertilizer, energy, ecological maintenance, etc. At the same time, solid-liquid separation of cow dung also reduces the pollution of cow dung to the environment.

[0003] At present, traditional solid-liquid separation equipment mainly separates the liquid and solid in cow dung through physical methods. However, there are also a large number of pathogens and parasites in cow dung. Traditional physical treatment methods cannot effectively render the pathogens and parasites in cow dung harmless. If cow dung that has not been effectively rendered harmless is directly discharged into the external environment, it will spread diseases and pollute the environment. If it is directly used as fertilizer, it will also bring diseases and pests to crops. There are obvious shortcomings. Utility Model Content

[0004] In order to improve the effect of harmless treatment of cow dung, the present application provides a cow dung solid-liquid separation device with a sterilization function.

[0005] The present application provides a cow dung solid-liquid separation device with sterilization function, which adopts the following technical solution:

[0007] By adopting the above technical solution, when cow dung needs to be processed, the operator adds the cow dung from the feed pipe into the processing box. During the process of the solid-liquid separation component processing the cow dung, the operator starts the water pump. Under the conveying action of the water pump, the disinfectant water in the disinfection water tank flows from the water supply pipe to the water outlet pipe, and finally sprays onto the cow dung in the processing box, thereby achieving the disinfection of pathogens and parasites in the cow dung, thereby reducing the adverse effects of the discharged cow dung on the environment, etc., and improving the effect of harmless treatment of cow dung.

[0009] By adopting the above technical solution, the annular water outlet pipe and the arrangement of multiple nozzle groups expand the effective area of the disinfectant water, thereby further improving the effect of harmless treatment of cow dung. At the same time, the inclined disinfectant water can also disinfect and clean the side walls of the treatment box, reducing the possibility of residual pathogens on the inner wall of the treatment box.

[0011] By adopting the above technical solution, the operator starts the first motor, and the first motor drives the spiral conveyor plate to rotate. When the spiral conveyor plate rotates, the cow dung will be displaced through the spiral cross-section, thereby realizing the transportation of the cow dung. During the transportation process, the liquid in the cow dung flows out from the water filter frame. At the same time, the setting of the spiral conveyor plate also realizes the turning over and stirring of the cow dung, thereby further improving the disinfection effect of the cow dung.

The drying component includes a hot air blower arranged on the outer wall of the drying box, and the hot air blower is provided with an air supply pipe. The air supply pipe is connected to the air outlet pipe, and the air outlet pipe is slidably arranged inside the drying box.

[0013] By adopting the above technical solution, the solid cow dung that has been disinfected and solid-liquid separated enters the drying box under the transportation of the spiral conveyor plate. At the same time, the operator starts the hot air blower, and the hot air flows into the drying box along the air supply pipe and the air outlet pipe. The hot air can further dry the cow dung while also further performing high-temperature disinfection on the cow dung, thereby further improving the effect of harmless treatment of the cow dung and improving the treatment efficiency of solid-liquid separation of the cow dung.

[0015] By adopting the above technical solution, the operator starts the second motor, and the second motor drives the screw to rotate. The rotation of the screw drives the air outlet pipe to move along the length direction of the drying box. During the movement of the air outlet pipe, the hot air continuously dries and sterilizes the cow dung in the drying box at high temperature, thereby expanding the contact area between the hot air and the cow dung, and further improving the effect of harmless treatment of the cow dung.

[0016] Optionally, a sterilization component is provided inside the drying box, and the sterilization component includes an ultraviolet sterilization lamp arranged on the top surface of the drying box, and a plurality of reflectors are provided on the inner wall of the drying box.

[0017] By adopting the above technical solution, the ultraviolet rays emitted by the ultraviolet sterilization lamp can effectively remove pathogens and parasites in cow dung. At the same time, by setting a reflector, it is ensured that the ultraviolet light emitted by the ultraviolet sterilization lamp can be repeatedly reflected by the reflector plate in the drying box, thereby extending the propagation path of the ultraviolet light, thereby expanding the scope of action of the ultraviolet light, further improving the effect of harmless treatment of cow dung, and further reducing the impact of the discharged cow dung on the environment.

In the initial state, the two discharge plates are horizontally arranged and abut against each other, a manure collection cart is provided under the discharge plate, and a discharge assembly is provided on the drying box.

[0019] By adopting the above technical solution, the cow dung entering the drying box from the discharge port is accumulated above the two unloading plates. When the drying and disinfection work is completed, the operator starts the unloading assembly, and the two unloading plates move away from each other. The solid cow dung that has been disinfected falls into the dung collection cart from the opening between the two unloading plates. The operator only needs to push the dung collection cart to quickly collect the cow dung. The whole process is quick and convenient, which is convenient for the operator.

The rotation of the worm drives the worm wheel engaged with the worm to rotate in the opposite direction. The rotation of the worm wheel drives the rotating shaft to rotate. The rotation of the rotating shaft drives the two unloading plates to rotate in opposite directions. An opening is formed between the two unloading plates, and the cow dung falls from the opening into the dung collection cart.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. This application provides a disinfectant water tank, a water pump, a water supply pipe, and a water outlet pipe. During the solid-liquid separation component's treatment of cow dung, the operator starts the water pump.

[0030] The following is combined with Figure 1-3 This application is described in further detail.

[0031] The embodiment of the present application discloses a cow dung solid-liquid separation device with a sterilization function.

[0032] Reference Figure 1 and Figure 2 A cow dung solid-liquid separation equipment with a sterilization function includes a frame 1, a processing box 2 is fixedly installed on the frame 1, a feeding pipe 21 and a discharging port 22 are provided on the processing box 2, a solid-liquid separation component 3 is provided in the processing box 2, a disinfection water tank 4 is fixedly installed on the top surface of the processing box 2, the disinfection water tank 4 stores disinfection water for disinfecting cow dung, a water supply pipe 41 is connected to the disinfection water tank 4, a water pump 42 is installed on the water supply pipe 41, a water outlet pipe 5 is connected to the water supply pipe 41, and the water outlet direction of the water outlet pipe 5 is toward the inside of the processing box 2, and a drying box 6 is connected at the discharging port 22, and a drying component 7 and a sterilization component 8 are provided inside the drying box 6.

[0033] When the cow dung needs to be processed, the operator adds the cow dung from the feed pipe 21 to the processing box 2. During the process of the solid-liquid separation component 3 processing the cow dung, the operator starts the water pump 42. Under the conveying action of the water pump 42, the disinfectant in the disinfectant tank 4 flows from the water supply pipe 41 to the outlet pipe 5, and finally sprays onto the cow dung in the processing box 2. During the contact process between the disinfectant and the cow dung, the pathogens and parasites in the cow dung are killed, and the content of pathogens and parasites in the cow dung is reduced, thereby improving the effect of harmless treatment of the cow dung and reducing the adverse effects of the discharged cow dung on the environment. The treated cow dung moves from the discharge port 22 to the drying box 6. Under the action of the drying component 7 and the sterilization component 8 in the drying box 6, the content of pathogens and parasites in the cow dung is further reduced, further improving the effect of harmless treatment of the cow dung.

[0034] Reference Figure 1 and Figure 2The outlet pipe 5 is annularly fixedly installed on the top surface of the interior of the treatment box 2, and a plurality of nozzle groups 9 are evenly distributed on the outlet pipe 5. The nozzle group 9 includes two inclined first nozzles 91 and a vertically arranged second nozzle 92. The second nozzle 92 is arranged in the middle position of the two first nozzles 91, and the water outlet direction of one of the first nozzles 91 is arranged toward the axis of the filter frame 33, and the water outlet direction of the other first nozzle 91 is arranged toward the inner side wall of the treatment box 2. The solid-liquid separation component 3 includes a first motor 31 fixedly installed on the side wall of the treatment box 2, and the output shaft of the first motor 31 is fixedly connected to the spiral conveying plate 32. The spiral conveying plate 32 is parallel to the length direction of the treatment box 2 and extends to the discharge port 22. A filter frame 33 is provided inside the treatment box 2, and the filter frame 33 is cylindrically sleeved on the outer surface of the spiral conveying plate 32. The spiral conveying plate 32 is rotatably connected to the inside of the treatment box 2. The bottom surface of the treatment box 2 is connected with a drain pipe 23, and the drain pipe 23 is connected to the main sewage pipe outside.

[0035] The operator adds cow dung into the processing box 2 from the feed pipe 21, and starts the first motor 31 and the water pump 42 at the same time. The first motor 31 drives the spiral conveying plate 32 to rotate. When the spiral conveying plate 32 rotates, the cow dung will be displaced through the spiral cross-section, and the cow dung will move toward the discharge port 22. During the transportation of the cow dung, the liquid in the cow dung flows out from the water filter frame, and the water pump 42 draws the disinfectant water in the disinfectant water tank 4 into the outlet pipe 5. The disinfectant water is finally sprayed out from the nozzle. The setting of multiple nozzle groups 9 expands the scope of action of the cleaning water. The disinfectant water in contact with the cow dung has a disinfecting effect on the cow dung, and the disinfectant water in contact with the inner wall of the processing box 2 has a cleaning and disinfecting effect on the processing box 2, thereby reducing the possibility of cow dung adhering to the inner wall of the processing box 2. At the same time, the setting of the spiral conveying plate 32 also realizes the turning and stirring of the cow dung, expands the contact area between the cleaning water and the cow dung, thereby further improving the effect of harmless treatment of the cow dung, and the separated sewage is discharged from the drain pipe 23 into the main sewage pipe.

[0036] Reference Figure 1 、 Figure 2 and Figure 3 The drying component 7 includes a hot air blower 71 fixedly mounted on the top surface of the drying box 6. The air outlet of the hot air blower 71 is connected to an air supply pipe 72. One end of the air supply pipe 72 extends to the interior of the processing box 2 and is connected to an air outlet pipe 73. The air outlet direction of the air outlet pipe 73 is set toward the cow dung in the drying box 6. The air outlet pipe 73 is slidably set inside the processing box 2. One end of the drying box 6 is rotatably connected to a screw 10, and the other end is fixedly mounted on a guide rod 11. One end of the air outlet pipe 73 is threadedly connected to the screw 10, and the other end is slidably connected to the guide rod 11. A second motor 12 is fixedly mounted on the outer wall of the drying box 6, and the output shaft of the second motor 12 is fixedly connected to the screw 10.

[0037] Under the conveyance of the spiral conveyor plate 32, the solid cow dung that has undergone disinfection and solid-liquid separation treatment enters the drying box 6. At the same time, the operator starts the hot air blower 71 and the second motor 12. The second motor 12 drives the screw 10 to rotate. The rotation of the screw 10 drives the air outlet pipe 73 to move along the length direction of the drying box 6. During the movement of the air outlet pipe 73, the hot air continues to dry and disinfect the cow dung in the drying box 6. The setting of the screw 10 expands the contact area between the hot air and the cow dung, further improving the effect of harmless treatment of the cow dung.

[0038] Reference Figure 2 and Figure 3 The sterilization assembly 8 includes a plurality of ultraviolet sterilization lamps 81 fixedly mounted on the top surface of the drying box 6. In this embodiment, the number of ultraviolet sterilization lamps 81 is 3, and a reflector 82 is mounted on the inner wall of the drying box 6.

[0039] The ultraviolet rays emitted by the ultraviolet sterilization lamp 81 can effectively remove pathogens and parasites in cow dung. At the same time, by setting up the reflector 82, it is ensured that the ultraviolet light emitted by the ultraviolet sterilization lamp 81 can be repeatedly reflected by the reflector 82 plate in the drying box 6, extending the propagation path of the ultraviolet light, thereby expanding the scope of action of the ultraviolet light, further improving the effect of harmless treatment of cow dung, and further reducing the impact of the discharged cow dung on the environment.

[0040] Reference Figure 2 and Figure 3 The bottom surface of the drying box 6 is rotatably connected to two rotating shafts 13, which are respectively distributed at both ends of the drying box 6. Discharge plates 131 are fixedly installed on the outer surfaces of the two rotating shafts 13. When cow dung accumulates above the discharge plates 131, the two discharge plates 131 are both horizontally arranged and the opposite side walls are close to each other. A dung collection cart 15 is provided below the discharge plates 131, and a discharge assembly 14 is provided on the side wall of the drying box 6.

[0041] The unloading assembly 14 includes a worm 141 rotatably connected to the outer wall of the drying box 6. The spiral rotation directions of the two ends of the worm 141 are opposite. The two ends of the worm 141 are meshed with worm wheels 142. The worm wheel 142 is fixedly connected to the nearby rotating shaft 13. A third motor 143 is fixedly connected to the outer wall of the drying box 6. The output shaft of the third motor 143 is fixedly connected to the worm 141. Weighing sensors 144 are fixedly installed on the bottom surfaces of the two unloading plates 131.

[0042] When the weighing sensor 144 detects that the cow dung on the discharge plate 131 reaches a certain weight, the third motor 143 is started, and the third motor 143 drives the worm 141 to rotate. The rotation of the worm 141 drives the worm gear 142 engaged with the worm 141 to rotate in the opposite direction. The rotation of the worm gear 142 drives the rotating shaft 13 to rotate. The rotation of the rotating shaft 13 drives the two discharge plates 131 to rotate in opposite directions. An opening is formed between the two discharge plates 131, and the cow dung falls into the dung collection cart 15 from the opening. At this time, the operator can quickly collect the sterilized cow dung by pushing the dung collection cart 15. The whole process is quick and convenient, which is convenient for the operator.

[0043] The implementation principle of the cow dung solid-liquid separation equipment with a sterilization function in the embodiment of the present application is as follows: when the cow dung needs to be processed, the operator adds the cow dung from the feed pipe 21 into the processing box 2, and then starts the first motor 31 and the water pump 42. The first motor 31 drives the spiral conveying plate 32 to rotate. When the spiral conveying plate 32 rotates, the cow dung will be displaced through the spiral cross-section, and the cow dung will move toward the discharge port 22. During the transportation of the cow dung, the liquid in the cow dung flows out from the water filter frame. Under the transportation action of the water pump 42, the disinfectant water in the disinfectant water tank 4 flows from the water supply pipe 41 to the water outlet pipe 5, and is finally sprayed onto the cow dung in the processing box 2. In the process of contact between the disinfectant water and the cow dung, the pathogens and parasites in the cow dung are disinfected, and the content of pathogens and parasites in the cow dung is reduced, thereby The effect of harmless treatment of cow dung is improved. The treated cow dung moves from the discharge port 22 to the drying box 6. Under the action of the drying component 7 and the sterilization component 8 in the drying box 6, the content of pathogens and parasites in the cow dung is further reduced, which further improves the effect of harmless treatment of cow dung and reduces the adverse effects of the discharged cow dung on the environment. When the weighing sensor 144 detects that the cow dung on the discharge plate 131 reaches a certain weight, the third motor 143 drives the worm 141 to rotate, and the rotation of the worm 141 drives the two discharge plates 131 to rotate in opposite directions. An opening is formed between the two discharge plates 131, and the cow dung falls from the opening into the dung collection cart 15. At this time, the operator can quickly collect the sterilized cow dung by pushing the dung collection cart 15.

[0044] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
