During the process of high-temperature sterilization of feces by stirring in the drum body, the feed valve and the discharge valve are both in a closed state.

[0004] The processes of feeding and discharging materials from the above-mentioned mixing barrel need to be carried out separately, which is bound to consume a lot of time, resulting in reduced feces treatment efficiency and obvious shortcomings. Summary of the invention

[0005] In order to improve the problem of low feces treatment efficiency, the present application provides a feces and sewage multi-effect sterilization direct use system.

[0006] The present application provides a direct-use system for multi-effect sterilization of feces and sewage, which adopts the following technical solutions:

[0008] By adopting the above technical solution, the feces are transferred from the highest conveyor belt to the lower conveyor belt from top to bottom, and the carbon crystal plate is energized to generate heat radiation, thereby drying the feces. In this process, the loading and unloading of feces can be carried out continuously without affecting the transmission of feces, so the feces treatment efficiency is relatively high.

[0009] Optionally, a temperature sensor is provided on the mounting bracket at a position relative to the highest point of the tail end of the conveyor belt, and the temperature sensor is used to detect the temperature of feces and is electrically connected to the conveyor belt through a control system.

[0010] By adopting the above technical solution, the temperature sensor detects the temperature of the feces at the corresponding position, so that the workers can adjust the transmission speed of the conveyor belt through the control system according to the difference between the actual temperature and the theoretical temperature to ensure that the feces are fully dried.

[0011] Optionally, a plurality of ultraviolet sterilization lamps are arranged on the mounting bracket at a position relative to the conveyor belt.

[0012] By adopting the above technical solution, the ultraviolet rays emitted by the ultraviolet sterilization lamp can sterilize the surface of feces.

[0013] Optionally, the mounting bracket is provided with a plurality of sterilization nozzles facing the conveyor belt, and the plurality of sterilization nozzles are all connected to an ozone generator.

[0014] By adopting the above technical solution, the ozone gas produced by the ozone generator is sprayed onto the feces through the sterilization nozzle, and the ozone gas can enter the feces and sterilize it.

[0015] Optionally, an electronic belt scale electrically connected to the control system is provided at a position of the mounting bracket relative to the lowest tail end of the conveyor belt.

[0016] By adopting the above technical solution, the electronic belt scale can weigh the feces transported by the conveyor belt per unit time, so as to adjust the metering of feces feed per unit time.

[0017] Optionally, except for the lowest conveyor belt, the mounting bracket is provided with a crushing mechanism at a position relative to the tail end of the remaining conveyor belts, the crushing mechanism includes a crushing part and a driving part, the crushing part includes a crushing bucket with openings on the top and bottom, a plurality of crushing pressure plates are arranged from top to bottom in the crushing bucket, the crushing pressure plates are slidably matched with the crushing bucket, and the driving part is used to drive the crushing pressure plates to slide back and forth in the crushing bucket.

[0018] By adopting the above technical solution, when the feces on the high conveyor belt falls to the low conveyor belt, the driving unit will drive the crushing unit to reciprocate, so that the crushing unit can squeeze and crush the block feces in the crushing bucket, which is beneficial to improve the subsequent sterilization effect of the feces.

[0019] Optionally, a limit blind groove is formed on the inner wall of the crushing bucket relative to the position of each crushing pressure plate, and a limit block is provided on the crushing pressure plate to slide in the limit blind groove. A return compression spring is supported between the side of the limit block facing away from the extrusion surface of the corresponding crushing pressure plate and the end of the corresponding limit blind groove.

[0020] By adopting the above technical solution, the output shaft of the motor drives the lever to rotate through the rotating shaft, and the two levers act on the ends of the elastic rods at the same time, thereby pushing the elastic rods to slide on the mounting bracket. The elastic rods pull the crushing plates in sequence from top to bottom through the pull wire, and the crushing plates squeeze the reset springs through the limit blocks, and the elastic rods bend and deform under the action of the reaction force. When the elastic rod is deformed to the maximum extent and is out of contact with the lever, it recovers its deformation and is reset under the action of the reset spring. The reset spring pushes the corresponding crushing plate to move back, and each crushing plate cooperates with the inner wall of the crushing bucket to squeeze and crush the feces in turn.

[0021] Optionally, a clearing inclined plate is provided on the side of the inner wall of the crushing bucket opposite to the pull wire, and the clearing inclined plate is inclined downward in a direction away from the tail of the corresponding conveyor belt. When the deformation degree of the elastic rod is the largest, the lowest point of the clearing inclined plate is exactly flush with the crushing surface of the highest crushing pressure plate.

[0022] By adopting the above technical solution, the cleaning inclined plate can push down the feces on the uppermost crushing inclined plate, thereby reducing the possibility of feces remaining in the crushing bucket.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The feces are transferred from the highest conveyor belt to the lower conveyor belt from top to bottom.

[0032] The following is combined with Figure 1-5 This application is described in further detail.

[0033] The embodiment of the present application discloses a direct-use system for multi-effect sterilization of feces and sewage.

[0034] Reference Figure 1 The direct-use multi-effect sterilization system for manure and sewage includes a mounting bracket 1 welded from multiple steels of different lengths. Three horizontally arranged conveyor belts 4 are bolted on the mounting bracket 1 from top to bottom, and the tail of the upper conveyor belt 4 is located between the head and tail ends of the adjacent conveyor belt 4 below.

[0035] Reference Figure 1 Under the conveying action of the conveyor belt 4, the feces falls from the high conveyor belt 4 to the low conveyor belt 4. When the feces are located on different conveyor belts 4, different processing steps are performed, and the feces after the processing is completely dropped from the tail of the lowest conveyor belt 4.

[0036] Reference Figure 1 The mounting bracket 1 is bolted with a sterilization cover 2 at a position above the highest conveyor belt 4. The sterilization cover 2 remains horizontal and its longitudinal section is in an inverted concave shape. The coverage range of the sterilization cover 2 in the length direction is roughly from the first section of the highest conveyor belt 4 to the midpoint of its length.

[0037] Reference Figure 1 A plurality of carbon crystal plates (not shown in the figure) electrically connected to the control system are bolted inside the sterilization cover 2 along its length direction. When the carbon crystal plates are energized, they can generate infrared heat radiation with strong penetrating power, so that the feces can be heated from the inside and dried quickly.

[0038] Since the gas produced by feces fermentation is flammable to a certain extent, and the high-temperature sterilization process of feces by carbon crystal plates does not produce open flames, it is less likely to cause fire and explosion and has higher safety.

[0039] In addition, workers can also adjust the intensity of heat radiation through the control system according to the thickness of feces on the conveyor belt 4. Different intensities of heat radiation mean different penetration thicknesses, thereby improving the drying effect of feces.

[0040] When the feces are within the coverage of the sterilization cover 2, the temperature of the feces is maintained at about 125° C. When the feces are moved out of the coverage of the sterilization cover 2, the temperature of the feces gradually decreases and is maintained at about 90° C.

[0041] Reference Figure 1 A temperature sensor (not shown in the figure) is threadedly connected to the position of the mounting bracket 1 at the tail of the highest conveyor belt 4, and the temperature sensor is electrically connected to the conveyor belt 4 through the control system. The temperature sensor can detect the temperature of the feces at the corresponding position, and adjust the conveying speed of the conveyor belt 4 by comparing the actual temperature of the feces with the theoretical temperature.

[0042] In addition, a humidity sensor (not shown in the figure) is threadedly connected to the mounting bracket 1. The humidity sensor is electrically connected to the conveyor belt 4 through the control system. The humidity sensor is used to detect the amount of moisture contained in the feces, thereby adjusting the transmission speed of the conveyor belt 4.

[0043] Reference Figure 2 Except for the highest conveyor belt 4, the mounting bracket 1 is threadedly connected with multiple ultraviolet germicidal lamps 5 at positions relative to the other two conveyor belts 4. After the ultraviolet germicidal lamp 5 is powered on, the ultraviolet rays generated are irradiated to the surface of the feces, thereby achieving sterilization treatment on the surface of the feces.

[0044] Reference Figure 2 The mounting bracket 1 is also threadedly connected to a plurality of sterilizing nozzles 6 at a position relative to the lowest conveyor belt 4. The sterilizing nozzles 6 face the feces on the conveyor belt 4. The plurality of sterilizing nozzles 6 are commonly connected to an ozone generator (not shown in the figure).

[0045] The ozone gas produced by the ozone generator is sprayed onto the feces through the sterilization nozzle 6. The ozone gas can enter the interior of the feces and undergo an oxidation reaction, thereby sterilizing the interior of the feces.

[0046] Under the combined action of the ozone gas and the ultraviolet germicidal lamp 5, the feces on the lowest conveyor belt 4 are sterilized both inside and outside, thereby greatly improving the sterilization effect on the feces.

[0047] Reference Figure 2 The mounting bracket 1 is bolted with an electronic belt scale 7 at the position relative to the tail end of the lowest conveyor belt 4, and the electronic belt scale 7 is electrically connected to the control system. The electronic belt scale 7 can weigh the feces transported by the conveyor belt 4 per unit time, thereby adjusting the metering of the feces fed per unit time.

[0048] Reference Figure 1By setting the above-mentioned conveyor belt 4, feces can be continuously fed and discharged without affecting its high-temperature sterilization treatment, which greatly improves the processing efficiency of feces.

[0049] Reference Figure 1 and Figure 3 After the feces are dried, they may solidify into large blocks, and it is difficult to sterilize the block feces. Therefore, except for the lowest conveyor belt 4, the mounting bracket 1 is provided with a crushing mechanism 8 for crushing the feces at the rear end of the other conveyor belts 4.

[0050] Reference Figure 3 , Figure 4 and Figure 5 The crushing mechanism 8 includes a crushing part for squeezing and crushing the feces, and a driving part for driving the crushing part to realize reciprocating motion.

[0051] The crushing part includes a crushing bucket 81 which is hollow inside and opened at the top and bottom. A plurality of horizontal crushing plates 82 are arranged in the crushing bucket 81 from top to bottom. Two vertically adjacent crushing plates 82 are close to each other. The plurality of crushing plates 82 slide out from the same side of the crushing bucket 81. The opening at the bottom of the crushing bucket 81 is close to the other side of the crushing plate 82 which slides out of the crushing bucket 81.

[0052] Reference Figure 3 , Figure 4 and Figure 5 A limiting blind groove 810 is formed on the inner wall of the crushing bucket 81 relative to each crushing plate 82, and a limiting block 83 is welded on the crushing plate 82 to slide in the limiting blind groove 810. A return compression spring 84 is supported between the side of the limiting block 83 facing away from the extrusion surface of the corresponding crushing plate 82 and the end of the corresponding limiting blind groove 810.

[0053] Reference Figure 3 , Figure 4 and Figure 5 Except for the lowest crushing plate 82, the other crushing plates 82 are vertically fixed with a push pin 85. Except for the highest crushing plate 82, the other crushing plates 82 are provided with a push slot 821 parallel to the corresponding conveyor belt 4. The push pin 85 and the push slot 821 on two vertically adjacent crushing plates 82 are plugged and slidably matched.

[0054] Reference Figure 3 , Figure 4 and Figure 5 The driving part includes an elastic rod 86 slidably arranged on the mounting bracket 1 along the length direction of the corresponding conveyor belt 4, and a pull wire 87 is tied between the elastic rod 86 and the highest crushing pressure plate 82.

[0055] The mounting bracket 1 is rotatable relative to a position below the elastic rod 86 and is penetrated by a rotating shaft 88. One end of the rotating shaft 88 is coaxially connected to a motor 89 bolted to the mounting bracket 1. Two levers 90 are also threadedly connected to the rotating shaft 88. One lever 90 corresponds to one end of the elastic rod 86, and the lever 90 is used to move the corresponding end of the elastic rod 86.

[0056] Reference Figure 3 , Figure 4 and Figure 5 The output shaft of the motor 89 drives the rotating shaft 88 to rotate, and the rotating shaft 88 drives the lever 90 to rotate. The two levers 90 act on the ends of the elastic rod 86 at the same time, thereby pushing the elastic rod 86 to slide on the mounting bracket 1.

[0057] The elastic rod 86 pulls each crushing plate 82 to move in sequence from top to bottom through the pull wire 87, and the crushing plate 82 squeezes the return compression spring 84 through the limit block 83, and the elastic rod 86 is bent and deformed under the action of the reaction force.

[0058] When the elastic rod 86 is deformed to the maximum extent and is out of contact with the lever 90, it recovers its deformation and is reset under the action of the reset spring 84. The reset spring 84 pushes the corresponding crushing plate 82 to move back. Each crushing plate 82 cooperates with the inner wall of the crushing bucket 81 to squeeze and crush the feces in turn.

[0059] Since the opening at the bottom of the crushing bucket 81 is narrow and long, the feces will fall out of the opening at the bottom only after being crushed to a sufficiently small degree by the crushing mechanism 8 for multiple times.

[0060] Reference Figure 3 , Figure 4 and Figure 5 A cleaning inclined plate 9 is bolted to the side of the inner wall of the crushing bucket 81 opposite to the pull wire 87. The cleaning inclined plate 9 is inclined downward in the direction away from the tail of the corresponding conveyor belt 4. When the deformation degree of the elastic rod 86 is the largest, the lowest point of the cleaning inclined plate 9 is just flush with the crushing surface of the highest crushing pressure plate 82.

[0061] The arrangement of the cleaning inclined plate 9 plays a role in pushing the material, thereby reducing the possibility of feces remaining on the highest crushing pressing plate 82.

[0062] The implementation principle of the direct-use system for multi-effect sterilization of feces and sewage in the embodiment of the present application is as follows:

[0063] The feces first moves from the first section of the highest conveyor belt 4 to the coverage of the sterilization cover 2. At this time, the heat radiation emitted by the carbon crystal plate sterilizes the feces at high temperature, and the feces is kept at about 120°C.

[0064] The feces are moved out of the coverage of the sterilization cover 2 by the conveyor belt 4, and the feces are gradually cooled to about 90° C. and are kept warm.

[0065] The temperature sensor detects the temperature of the feces at the tail end of the highest conveyor belt 4. When there is a gap between the actual detected temperature and the theoretical temperature, the worker adjusts the transmission speed of the corresponding conveyor belt 4 through the control system.

[0066] Feces falls from the tail end of the highest conveyor belt 4 into the crushing bucket 81, and the output shaft of the corresponding motor 89 drives the lever 90 to rotate through the rotating shaft 88. The two levers 90 act on the ends of the elastic rod 86 at the same time, thereby pushing the elastic rod 86 to slide on the mounting bracket 1. The elastic rod 86 pulls each crushing plate 82 to move in sequence from top to bottom through the pull wire 87. The crushing plate 82 squeezes the reset spring 84 through the limit block 83, and the elastic rod 86 bends and deforms under the action of the reaction force. When the elastic rod 86 is deformed to the maximum degree and breaks away from the contact with the lever 90, it recovers its deformation and resets under the action of the reset spring 84. The reset spring 84 pushes the corresponding crushing plate 82 to move back, and each crushing plate 82 cooperates with the inner wall of the crushing bucket 81 to squeeze and crush the feces in turn.

[0067] The fully crushed feces falls from the opening at the bottom of the crushing bucket 81 onto the conveyor belt 4 at the middle position. During the process of the conveyor belt 4 conveying the feces, the ultraviolet sterilization lamp 5 on the mounting bracket 1 sterilizes the surface of the feces.

[0068] When the feces falls from the tail end of the conveyor belt 4 at the middle position into the corresponding crushing bucket 81 again, it is crushed for the second time, and then the feces falls onto the conveyor belt 4 at the lowest position.

[0069] During the process of the lowest conveyor belt 4 conveying the feces, the ozone gas sprayed by the ultraviolet sterilization lamp 5 and the sterilization nozzle 6 cooperates to sterilize the feces from the inside and outside. Finally, the feces falls from the tail end of the lowest conveyor belt 4 after being weighed by the electronic belt scale 7.

[0070] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
