[0002] In rural areas, toilets are mostly dry toilets, which mainly treat sewage through natural evaporation. However, the sewage accumulates in dry toilets for a long time without being effectively treated, which makes the sewage in rural toilets easily pollute the environment. At the same time, sewage can be converted into organic fertilizer through certain technical means, but sewage that has not been effectively treated for a long time cannot be reused.

[0017] Beneficial effects: The present invention provides a septic tank device for rural sanitary toilets, which has the following beneficial effects: 1. In the present invention, the reduction motor drives the rotation of the reciprocating screw through its output shaft. When the reciprocating screw rotates, the up and down reciprocating stirring mechanism can reciprocate up and down, and while reciprocating up and down, the manure and microbial flora in the manure reaction box are uniformly stirred, and the manure is continuously fermented during the stirring process to accelerate the process of converting the manure into organic fertilizer.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Embodiment 1 like Figure 1-8 As shown, the present invention provides a technical solution: A septic tank device for rural sanitary toilets, comprising: A manure reaction box 10, with a feeding pipe 101 on one side of the top of the manure reaction box 10, the feeding pipe 101 is used to fill the manure and microbial flora reaction agent, and both sides of the bottom of the manure reaction box 10 are provided with discharge pipes 102; Two valves 20, the two valves 20 are respectively fixedly mounted on the corresponding discharge pipes 102, and are used to control the opening and closing of the corresponding discharge pipes 102; The reduction motor 30 is fixedly mounted at the top center of the manure reaction box 10, and the output shaft of the reduction motor 30 passes through the top of the manure reaction box 10 downward and extends to the top of the inner cavity of the manure reaction box 10; A reciprocating screw 40 is arranged at the center of the inner cavity of the manure reaction box 10, one end of the top of the reciprocating screw 40 is fixedly connected to the end of the output shaft of the reduction motor 30, and one end of the bottom of the reciprocating screw 40 is rotatably installed in a groove opened at the center of the bottom of the inner cavity of the manure reaction box 10; A ball guide sleeve 50, wherein the ball guide sleeve 50 is sleeved and mounted on the reciprocating screw 40; The up-and-down reciprocating stirring mechanism is installed on the ball guide sleeve 50. The reduction motor 30 can drive the rotation of the reciprocating screw 40 through its output shaft. When the reciprocating screw 40 rotates, the up-and-down reciprocating stirring mechanism can reciprocate up and down, and while reciprocating up and down, the waste manure and microbial flora in the manure reaction box 10 are uniformly stirred, and the waste manure is continuously fermented during the stirring process; Two unloading augers 120, the two unloading augers 120 are rotatably mounted on both sides of the inner cavity of the manure reaction box 10, and the axis of each unloading augers 120 coincides with the axis of the corresponding unloading pipe 102, and the top shaft of each unloading augers 120 penetrates the top of the manure reaction box 10 upward; Two material shifting racks 140, the two material shifting racks 140 are respectively fixedly mounted on one end of the bottom of the shaft of the corresponding unloading auger 120; and The power mechanism includes a driving part, a transmission member connected to the driving part, two transmission ends connected to the transmission member, and a tensioning end arranged on the transmission member. The driving part is installed on the manure reaction box 10, the two transmission ends are installed on the top end of the corresponding unloading auger 120, the tensioning end is installed on the manure reaction box 10, and the transmission member is installed between the driving part, the two transmission ends and the tensioning end; Among them, the structure between the driving part, the transmission part, the two transmission ends and the tensioning end is V-shaped. The driving part, the transmission part, the two transmission ends and the tensioning end of the power mechanism are arranged in a V-shaped structure. This layout design makes the power transmission more stable and reliable; The power mechanism can make the two feeding augers 120 rotate synchronously in the inner cavity of the manure reaction box 10 , and the two material diverter racks 140 can also rotate synchronously with the rotation of the corresponding feeding augers 120 .

[0026] In this embodiment, when converting sewage into organic fertilizer, sewage in rural dry toilets is loaded into the feeding pipe 101. After the sewage is loaded, the microbial flora reaction agent is added into the feeding pipe 101 according to a proportion. At this time, the loaded sewage is mixed and stirred to accelerate the reaction between the microbial flora and sewage. Through the reaction between the microbial flora and sewage, the sewage is converted into organic fertilizer. Specifically: The reduction motor 30 drives the reciprocating screw 40 to rotate through its output shaft. When the reciprocating screw 40 rotates, the up and down reciprocating stirring mechanism can reciprocate up and down, and while reciprocating up and down, the sewage and microbial flora in the sewage reaction box 10 are uniformly stirred, and the sewage is continuously fermented during the stirring process to accelerate the process of converting the sewage into organic fertilizer.

[0027] When the waste manure in the manure reaction box 10 is fermented into organic fertilizer, the reduction motor 30 stops working.

[0028] At this time, the waste manure in the manure reaction box 10 is in a state of being unloaded. When unloading, the specific operation is: Open the two valves 20 to connect the two discharge pipes 102 with the inner cavity of the manure reaction box 10 for easy discharge, and start the power mechanism at the same time. The driving part in the power mechanism can drive the transmission member when working, and the rotating member can drive the two transmission ends through its own movement. The tensioning end arranged between the two transmission ends can improve the tightness and transmission efficiency between the transmission member and the two transmission ends; Furthermore, when the two transmission ends of the transmission member are in operation, they can synchronously drive the two unloading augers 120, and when the two unloading augers 120 are in synchronous operation, they can synchronously drive the corresponding material shifting racks 140. Therefore, the power mechanism can make the two unloading augers 120 rotate synchronously in the inner cavity of the manure reaction box 10, and the material shifting racks 140 respectively fixedly mounted on one end of the bottom of the shaft of the corresponding unloading augers 120 can also rotate synchronously. When the two unloading augers 120 rotate synchronously in the inner cavity of the manure reaction box 10, the organic fertilizer on the upper layer can be continuously transported to the lower layer in the form of a spiral motion, and when the material shifting rack 140 rotates, the organic fertilizer at the bottom can be shifted into the discharge pipe 102, so that the organic fertilizer in the manure reaction box 10 can continuously flow into the discharge pipe 102, thereby effectively improving the speed of unloading the organic fertilizer and thus shortening the unloading time.

[0029] like Figure 8As shown, further, electric heating plates 1150 are fixedly installed on the opposite side walls of the manure reaction box 10.

[0030] In this embodiment, two electric heating plates 1150 can heat the body of the manure reaction box 10. The two electric heating plates 1150 cover from the upper part of the side wall of the manure reaction box 10 to the lower part of the side wall. Therefore, the temperature of the two electric heating plates 1150 during heating is more balanced. When the manure in the manure reaction box 10 moves with the up and down reciprocating stirring mechanism, it can be heated at different levels, thereby improving the fermentation efficiency of the manure.

[0031] Embodiment 2 like Figure 1-8 As shown, based on the first embodiment, the following improvements are made: Furthermore, the up-and-down reciprocating stirring mechanism includes a stirring frame 60, and first hollow grooves 601 are provided on opposite sides of the stirring frame 60, and second hollow grooves 602 are provided on the upper and lower parts of the stirring frame 60 and located between the two first hollow grooves 601; The two first hollow grooves 601 and the two second hollow grooves 602 are both equipped with spiral stirring components; Guide rods 110 are installed on the four corners of the stirring frame 60, and the top end of each guide rod 110 is fixedly connected to the top of the inner cavity of the manure reaction box 10, and the bottom end of each guide rod 110 is fixedly connected to the bottom of the inner cavity of the manure reaction box 10; An assembly hole 604 is formed at the center of the stirring frame 60 , and the stirring frame 60 is sleeved and fixed on the ball guide sleeve 50 through the assembly hole 604 .

[0032] In this embodiment, the stirring frame 60 is fixed on the ball guide sleeve 50 through the assembly hole 604 at the center thereof, so the stirring frame 60 will reciprocate up and down together with the ball guide sleeve 50. Guide rods 110 are installed on the four corners of the stirring frame 60. The function of these guide rods 110 is to ensure that the stirring frame 60 can stably run along a straight line during the up and down reciprocating motion, and prevent the stirring frame 60 from deflecting or shaking during the motion. When the stirring frame 60 reciprocates up and down with the ball guide sleeve 50, the spiral stirring components installed in the first hollow groove 601 and the second hollow groove 602 will stir the manure and microbial flora reactants at different height levels in the manure reaction box 10. Since the up and down reciprocating motion of the stirring frame 60 covers different height areas in the manure reaction box 10, and the distribution of the spiral stirring components in each hollow groove makes the stirring range more comprehensive, it can achieve all-round, multi-level and uniform stirring of the manure and microbial flora in the manure reaction box 10, greatly improving the fermentation efficiency and accelerating the process of converting manure into organic fertilizer.

[0033] Furthermore, the spiral stirring assembly includes a first U-shaped fixing frame 70 fixedly mounted on the upper and lower parts of the inner cavity of the first hollow groove 601, and at least three first stirring impellers 80 are rotatably mounted between the two first U-shaped fixing frames 70; The spiral stirring assembly also includes second Chinese-Japanese-style fixing frames 90 fixedly mounted on the upper and lower parts of the inner cavity of the second hollow groove 602 , and a second stirring impeller 100 is rotatably mounted between the two second Chinese-Japanese-style fixing frames 90 .

[0034] In this embodiment, when the stirring frame 60 moves up and down, the first stirring impeller 80 rotates in the first hollow groove 601 along with the movement of the stirring frame 60, and the second stirring impeller 100 also rotates in the second hollow groove 602 along with the movement of the stirring frame 60; Since the first stirring impeller 80 is rotatably mounted between the two first U-shaped fixing frames 70, and the second stirring impeller 100 is rotatably mounted between the two second U-shaped fixing frames 90, the two impellers can effectively cut into the sewage and feces during their rotation, break up the sewage and feces, and fully mix them with the microbial flora; The arrangement of multiple first stirring impellers 80 and two second stirring impellers 100 can make the stirring at the same height level more uniform and comprehensive. The first stirring impellers 80 at different height levels can also achieve multi-level stirring of sewage in different height areas in the sewage reaction box 10 as the stirring frame 60 moves up and down, further promoting the fermentation process of sewage.

[0035] Furthermore, guide holes 603 are provided at four corners of the stirring frame 60 , and each guide rod 110 is slidably installed in the corresponding guide hole 603 .

[0036] In this embodiment, the guide rods 110 installed at the four corners of the stirring frame 60 are slidably installed in the corresponding guide holes 603 to guide the up and down movement of the stirring frame 60.

[0037] Embodiment 3 like Figure 1-8 As shown, based on the first embodiment, the following improvements are made: Furthermore, the lower parts of the shafts of the two unloading augers 120 are sleeved with I-shaped fixing frames 130 , and both ends of the two I-shaped fixing frames 130 are fixedly mounted on the inner cavity side walls of the manure reaction box 10 .

[0038] In this embodiment, the I-shaped fixing frame 130 is installed at the bottom of the unloading auger 120 . When the unloading auger 120 rotates, the I-shaped fixing frame 130 provides support for the unloading auger 120 .

[0039] Embodiment 4 like Figure 1-8 As shown, based on the first embodiment, the following improvements are made: Furthermore, the driving part of the power mechanism includes a servo motor 150, which is fixedly mounted on the side wall of the manure reaction box 10, and a driving pulley 160 is fixedly mounted on the output shaft of the servo motor 150; The two transmission ends of the power mechanism include driven pulleys 170, and the two driven pulleys 170 are respectively fixedly mounted on the top ends of the corresponding unloading auger 120; The tensioning end includes a rotating rod 180 fixedly mounted on one side of the top of the manure reaction box 10, and a tensioning wheel 190 is rotatably mounted on the rotating rod 180; The transmission member is a transmission belt 1100, which is sleeved and installed between a driving pulley 160, two driven pulleys 170 and a tensioner 190; The driving pulley 160 , the two driven pulleys 170 and the tensioning pulley 190 are located on the same horizontal plane.

[0040] In this embodiment, when unloading begins, the servo motor 150 is started and its output shaft starts to rotate. Since the driving pulley 160 is fixedly mounted on the output shaft of the servo motor 150, as the output shaft of the servo motor 150 rotates, the driving pulley 160 also rotates synchronously. The transmission belt 1100 is sleeved and mounted between the driving pulley 160, the two driven pulleys 170 and the tensioner 190. When the driving pulley 160 rotates, the transmission belt 1100 simultaneously drives the rotation of the two driven pulleys 170 through the cooperation between the transmission belt 1100 and the two driven pulleys 170 and the tensioner 190. The rotation of the two driven pulleys 170 directly drives the rotation of the corresponding unloading auger 120, so that the unloading auger 120 can transport the organic fertilizer in the upper layer to the lower layer in the inner cavity of the manure reaction box 10 in a spiral motion.

[0041] The main function of the tensioner 190 is to adjust the tension of the transmission belt 1100 by adjusting its position.

[0042] Embodiment 5 like Figure 1-8 As shown, based on the first embodiment, the following improvements are made: Furthermore, the two material-diverting racks 140 each have a plurality of material-diverting claws, which are distributed in a circular pattern on the material-diverting rack 140 , and each of the material-diverting claws is arc-shaped.

[0043] In this embodiment, the material-moving claws on each material-moving rack 140 are used for moving materials. When the two material-moving racks 140 rotate synchronously with the corresponding unloading auger 120, the multiple material-moving claws of each material-moving rack 140 can move the organic fertilizer at the bottom of the inner cavity of the manure reaction box 10 into the discharge pipe 102 in a circular motion.

[0044] The arc-shaped structure of each material-moving claw can move more organic fertilizers, thereby further improving the speed of unloading the organic fertilizers.

[0045] Embodiment 6 like Figure 1-8 As shown, based on the first embodiment, the following improvements are made: Furthermore, a tempered glass window 1110 is embedded on one side wall of the manure reaction box 10 .

[0046] In this embodiment, during the operation of the septic tank device, the operator can visually observe the fermentation of the waste manure in the manure reaction box 10 through the tempered glass window 1110 .

[0047] Furthermore, an ultraviolet sterilization light box 1120 is provided on one side of the manure reaction box 10 corresponding to the tempered glass window 1110, and the ultraviolet irradiation surface of the ultraviolet sterilization light box 1120 faces the tempered glass window 1110. Light box brackets 1130 are fixedly installed at the four corners of the ultraviolet sterilization light box 1120, and the legs of the light box bracket 1130 are fixedly installed on the side wall of the manure reaction box 10.

[0048] In this embodiment, when the ultraviolet rays emitted from the irradiation surface of the ultraviolet sterilization lamp box 1120 continuously irradiate the tempered glass window 1110 for more than 30 minutes or 40 minutes, the manure reaction raw materials in the manure reaction box 10 can be sterilized.

[0049] Among them, four light box brackets 1130 are used to support the ultraviolet sterilization light box 1120. The length of the support legs of each light box bracket 1130 can be adjusted according to actual needs. Specifically, the length of the support legs of each light box bracket 1130 can be set to 3 cm, or to 5 cm. When the length of the support legs of each light box bracket 1130 is set to 3 cm, it can not only facilitate the operator to observe the feces reaction in the feces reaction box 10 through the tempered glass window 1110, but also enable the ultraviolet sterilization light box 1120 to be closer to the tempered glass window 1110 to improve the ultraviolet irradiation effect.

[0050] Embodiment 7 like Figure 1-8 As shown, based on the first embodiment, the following improvements are made: Furthermore, a cover 1140 is installed on the feeding tube 101 .

[0051] In this embodiment, the cover 1140 covers the feeding tube 101 to form an effective seal.

[0052] In summary, the workflow of the present invention is: like Figure 1-8As shown, when converting sewage into organic fertilizer, sewage in rural dry toilets is filled into the feeding pipe 101. After the sewage is filled, the microbial flora reaction agent is added into the feeding pipe 101 according to a proportion. At this time, the filled sewage is mixed and stirred to accelerate the reaction between the microbial flora and sewage. Through the reaction between the microbial flora and sewage, the sewage is converted into organic fertilizer. Specifically: The reduction motor 30 drives the reciprocating screw 40 to rotate through its output shaft. When the reciprocating screw 40 rotates, the up and down reciprocating stirring mechanism can reciprocate up and down, and while reciprocating up and down, the sewage and microbial flora in the sewage reaction box 10 are uniformly stirred, and the sewage is continuously fermented during the stirring process to accelerate the process of converting the sewage into organic fertilizer.

[0053] When the waste manure in the manure reaction box 10 is fermented into organic fertilizer, the reduction motor 30 stops working.

[0054] At this time, the waste manure in the manure reaction box 10 is in a state of being unloaded. When unloading, the specific operation is: Open the two valves 20 to connect the two discharge pipes 102 with the inner cavity of the manure reaction box 10 for easy discharge, and start the power mechanism at the same time. The driving part in the power mechanism can drive the transmission member when working, and the rotating member can drive the two transmission ends through its own movement. The tensioning end arranged between the two transmission ends can improve the tightness and transmission efficiency between the transmission member and the two transmission ends; Furthermore, when the two transmission ends of the transmission member are in operation, they can synchronously drive the two unloading augers 120, and when the two unloading augers 120 are in synchronous operation, they can synchronously drive the corresponding material shifting racks 140. Therefore, the power mechanism can make the two unloading augers 120 rotate synchronously in the inner cavity of the manure reaction box 10, and the material shifting racks 140 respectively fixedly mounted on one end of the bottom of the shaft of the corresponding unloading augers 120 can also rotate synchronously. When the two unloading augers 120 rotate synchronously in the inner cavity of the manure reaction box 10, the organic fertilizer on the upper layer can be continuously transported to the lower layer in the form of a spiral motion, and when the material shifting rack 140 rotates, the organic fertilizer at the bottom can be shifted into the discharge pipe 102, so that the organic fertilizer in the manure reaction box 10 can continuously flow into the discharge pipe 102, thereby effectively improving the speed of unloading the organic fertilizer and thus shortening the unloading time.

[0055] Specifically, the stirring frame 60 is fixed on the ball guide sleeve 50 through the assembly hole 604 at the center thereof, so the stirring frame 60 will reciprocate up and down together with the ball guide sleeve 50. Guide rods 110 are installed on the four corners of the stirring frame 60. The function of these guide rods 110 is to ensure that the stirring frame 60 can stably run along a straight line during the up and down reciprocating motion, and prevent the stirring frame 60 from deflecting or shaking during the motion. When the stirring frame 60 reciprocates up and down with the ball guide sleeve 50, the spiral stirring components installed in the first hollow groove 601 and the second hollow groove 602 will stir the waste manure and microbial flora reactants at different height levels in the manure reaction box 10. Since the up and down reciprocating motion of the stirring frame 60 covers different height areas in the manure reaction box 10, and the distribution of the spiral stirring components in each hollow groove makes the stirring range more comprehensive, it can achieve all-round, multi-level uniform stirring of the waste manure and microbial flora in the manure reaction box 10, greatly improving the fermentation efficiency and accelerating the process of converting waste manure into organic fertilizer; When the stirring frame 60 moves up and down, the first stirring impeller 80 rotates in the first hollow groove 601 along with the movement of the stirring frame 60, and the second stirring impeller 100 also rotates in the second hollow groove 602 along with the movement of the stirring frame 60; Since the first stirring impeller 80 is rotatably mounted between the two first U-shaped fixing frames 70, and the second stirring impeller 100 is rotatably mounted between the two second U-shaped fixing frames 90, the two impellers can effectively cut into the sewage and feces during their rotation, break up the sewage and feces, and fully mix them with the microbial flora; The arrangement of the plurality of first stirring impellers 80 and the two second stirring impellers 100 can make the stirring at the same height level more uniform and comprehensive. The first stirring impellers 80 at different height levels can also realize multi-level stirring of the waste manure at different height areas in the waste manure reaction box 10 as the stirring frame 60 moves up and down, further promoting the fermentation process of the waste manure. When the unloading starts, the servo motor 150 starts, and its output shaft starts to rotate. Since the driving pulley 160 is fixedly installed on the output shaft of the servo motor 150, as the output shaft of the servo motor 150 rotates, the driving pulley 160 also rotates synchronously, and the transmission belt 1100 is sleeved and installed between the driving pulley 160, the two driven pulleys 170 and the tensioning wheel 190. When the driving pulley 160 rotates, the transmission belt 1100 cooperates with the two driven pulleys 170 and the tensioning wheel 190, so that the transmission belt 1100 drives the rotation of the two driven pulleys 170 at the same time. The rotation of the two driven pulleys 170 directly drives the rotation of the corresponding unloading auger 120, so that the unloading auger 120 can transport the organic fertilizer in the upper layer to the lower layer in the inner cavity of the manure reaction box 10 in a spiral motion. The material-moving claws on each material-moving rack 140 are used for moving materials. When the two material-moving racks 140 rotate synchronously with the corresponding unloading auger 120, the multiple material-moving claws of each material-moving rack 140 can move the organic fertilizer at the bottom of the inner cavity of the manure reaction box 10 into the discharge pipe 102 in a circular motion.

[0056] The arc-shaped structure of each material-moving claw can move more organic fertilizers, thereby further increasing the speed of unloading organic fertilizers; During the operation of the septic tank device, the operator can visually observe the fermentation of the sewage in the sewage reaction box 10 through the tempered glass window 1110. When the ultraviolet rays emitted from the irradiation surface of the ultraviolet sterilization lamp box 1120 continuously irradiate the tempered glass window 1110 for more than 30 minutes or 40 minutes, the sewage reaction raw materials in the sewage reaction box 10 can be sterilized.

[0057] Among them, four light box brackets 1130 are used to support the ultraviolet sterilization light box 1120. The length of the support leg of each light box bracket 1130 can be adjusted according to actual needs. Specifically, the length of the support leg of each light box bracket 1130 can be set to 3 cm, or set to 5 cm. When the length of the support leg of each light box bracket 1130 is set to 3 cm, it is convenient for operators to observe the sewage and feces reaction in the feces reaction box 10 through the tempered glass window 1110, and it can also make the ultraviolet sterilization light box 1120 closer to the tempered glass window 1110 to improve the ultraviolet irradiation effect; The two electric heating plates 1150 can heat the body of the manure reaction box 10. The two electric heating plates 1150 cover from the upper part of the side wall of the manure reaction box 10 to the lower part of the side wall. Therefore, the temperature of the two electric heating plates 1150 during heating is more balanced. When the manure in the manure reaction box 10 moves with the up and down reciprocating stirring mechanism, it can be heated at different levels, thereby improving the fermentation efficiency of the manure.
