Description

Technical Field

[0001] The present application relates to the field of environmental protection equipment, and in particular to a feces collection and treatment system for water-saving and environmentally friendly toilets. Background Art

[0002] The main significance of urban sewage treatment is to ease water resource tension, improve the environment, promote the benign circulation of water resources and serve as a second water source. With the intensification of the global water resource crisis, sewage treatment and reuse has become an important way to ease water resource tension. Treated recycled sewage can be used as a new water source to promote the benign circulation of water resources and solve the problem of water shortage.

[0003] At present, the flow of people in some large cities above the second tier in my country is increasing dramatically every day. Many public toilets are planned and built for people to use, but the workload of municipal sewage treatment personnel has increased greatly. Therefore, a water-saving and environmentally friendly toilet has appeared on the market, which has the function of self-treatment of sewage and can help municipal departments to relieve the pressure of sewage treatment to a great extent. However, it is currently limited to the recycling and secondary use of water, and the recycling and reuse of feces is not mature. Summary of the invention

[0004] In view of this, the present application provides a feces residue collection and treatment system for a water-saving and environmentally friendly toilet, which solves the problems in the prior art, improves the feces residue recycling efficiency and insufficient recycling processing capacity.

[0005] The present application provides a water-saving and environmentally friendly toilet feces collection and treatment system using the following technical solutions:

[0006] A feces collection and treatment system for a water-saving and environmentally friendly toilet, comprising a treatment mechanism and a granulation mechanism, wherein the granulation mechanism comprises a pelletizing assembly, a drying assembly and a collecting box, a funnel is provided on the top of the collecting box, the pelletizing assembly is arranged in the collecting box, directly below the funnel, and the drying assembly is arranged below the pelletizing end of the pelletizing assembly; the treatment mechanism is located above the funnel, and is used for treating feces and conveying the treated feces to the pelletizing assembly for granulation.

[0007] By adopting the above technical scheme, the waste is first collected in the treatment mechanism, which removes the harmful and polluting substances it contains, and then performs solid-liquid separation. After the solid-liquid separation is completed, the solid feces residue is collected in the collection box. At this time, the solid feces residue has not drained all the water, so the feces residue must first be processed into granules by the pelletizing component, and then dried to a suitable degree by the drying component before being collected and reused. This greatly improves the treatment efficiency of the feces residue, and the treated feces residue can be directly used as fertilizer after collection, which is very convenient.

[0008] Optionally, the pelletizing assembly includes a linear electric cylinder, an extrusion plate, a mold plate, a rotating blade and a cutting motor, wherein the linear electric cylinder is arranged on the collection box and is located below the funnel; the extrusion plate is arranged at the pushing end of the linear electric cylinder and the pushing direction is horizontal; the mold plate is arranged in the collection box and is located at the far end of the pushing direction of the linear electric cylinder; the rotating blade is arranged on the side of the mold plate away from the extrusion plate, and the cutting motor is used to drive the rotating blade to rotate.

[0009] By adopting the above technical scheme, the manure residue after preliminary dehydration by the processing mechanism still contains some water, so the manure residue is plastic at this time. The manure residue is squeezed into strips on the mold through an extrusion plate, and then quickly cut by a rotating blade into particles of uniform size. The manure residue particles at this time are not easily blown away by the wind when dried and used, nor are they easy to absorb moisture and agglomerate, and can fully play its role in fertilizing the land.

[0010] Optionally, the drying component includes an isolation net and a hot air motor, there are multiple hot air motors, and the multiple hot air motors are arranged at the bottom of the collection box; the isolation net is arranged above the hot air motor; and a collection door is provided on the collection box on one side of the isolation net.

[0011] By adopting the above technical solution, the feces residue is first made into particles, which can ensure that it is not easy to fly around when heated by the hot air motor, and it is also more convenient for its subsequent use; when the feces residue particles are collected on the isolation net, the mesh size of the isolation net is much smaller than the particle size, thereby ensuring that the feces residue particles will not fall under the isolation net. After being heated by the hot air motor, the feces residue particles containing moisture will be dried, which is easier to store and further use, thereby improving its use efficiency.

[0012] Optionally, the processing mechanism includes a stirring component, a waste gas treatment component, a dehydration component and a processing box, the stirring component is used to collect dirt and preliminarily treat the dirt, the waste gas treatment component is arranged in the processing box, located above the processing box, and the dehydration component is arranged outside the processing box, located between the processing box and the collection box.

[0013] By adopting the above technical solution, when treating the waste, it is first stirred to break up and mix the solid matter therein, and microorganisms are added therein during the stirring process for reaction, and the harmful substances contained therein are absorbed by the microorganisms. Adding microorganisms during the stirring process is more conducive to the full absorption of harmful substances by the microorganisms. After the stirring is completed, the mixed slurry will be transferred and the waste gas will be treated, and the harmful gases and odors contained therein will be treated together. Only then can it be dehydrated and granulated for use. Setting the processing sequence in this order can treat the waste faster and make the processing efficiency higher.

[0014] Optionally, the stirring assembly includes a stirring tank, a stirring paddle, a liquid inlet pipe and a driving member, the liquid inlet pipe is arranged at the top of the stirring tank, and a valve is provided on the liquid inlet pipe; the stirring paddle has two groups, the two groups of stirring paddles are symmetrically arranged in the stirring tank, and are rotatably connected to the stirring tank; the driving member includes a driving motor, a driving gear and a driven gear, the driven gear is fixedly connected to the bottom of the stirring paddle, the driving gear is meshed with the driven gear, and the driving motor is used to drive the driving gear to rotate.

[0015] By adopting the above technical solution, two groups of stirring paddles are arranged, and the staggered arrangement of the two groups of stirring paddles is more conducive to cutting the solids in the dirt, and at the same time it can also improve its stirring efficiency and make it mix faster. Secondly, a valve is set in the liquid inlet pipe to prevent dirt from continuously entering the stirring tank during the stirring process, thereby affecting the stirring efficiency. Using one motor to drive the two groups of stirring paddles to rotate at the same time can further improve the working efficiency of the motor.

[0016] Optionally, there are two stirring tanks, and the two stirring tanks are arranged side by side; the liquid inlet pipe includes a main pipe and a branch pipe, there are two branch pipes, the two branch pipes are arranged below the main pipe, and the branch pipes are fixedly connected to the two stirring tanks respectively, and the valve is arranged on the two branch pipes.

[0017] By adopting the above technical solution, two stirring tanks are set, and corresponding valves are set for the corresponding stirring tanks so that when one of the stirring tanks is stirring, the other stirring tank can continue to collect waste, thereby improving the processing efficiency. At the same time, it is also more convenient to add microorganisms to the stirring tank during the stirring process, and microorganisms need an anaerobic environment when processing harmful substances in waste. Therefore, setting two groups of stirring tanks and setting valves separately can process waste faster, effectively improving the waste processing efficiency.

[0018] Optionally, connecting pipes are respectively provided between the two stirring tanks and the treatment box, and a vacuum pump is provided on the connecting pipes; the exhaust gas treatment component includes an exhaust fan, an ion generator, an exhaust pipe and an activated carbon layer, and a partition plate is provided in the upper half of the treatment box, and the exhaust fan is provided on the partition plate; the ion generator is provided above the partition plate and located in the treatment box; the exhaust pipe is provided at the top of the treatment box, and the activated carbon layer is provided in the exhaust pipe.

[0019] By adopting the above technical solution, after the stirred dirt is transferred to the treatment box by the vacuum pump, the odor and waste gas contained in the dirt will be emitted faster after being fully stirred, so it is easier to suck it into the position of the ion generator through the exhaust fan. The positive and negative ions generated by the ion generator are combined with the ions in the odor, thereby performing the first step of treating the odor. Then, under the continued action of the exhaust fan, the combined odor will be discharged from the exhaust pipe. The treated odor will be further adsorbed by activated carbon in the exhaust pipe, thereby effectively reducing odor pollution and effectively improving environmental protection efficiency.

[0020] Optionally, the dehydration assembly includes a spiral extrusion sheet, a water filter trough and a water collection pool, the bottom of the processing box is inclined, and a water filter hole is provided at the bottom of the processing box; a discharge door is provided on the side of the processing box close to the water filter trough, the discharge door is rotatably connected to the processing box, and a flip motor is provided at the rotating connection of the discharge door; the spiral extrusion sheet is arranged in the water filter trough and arranged along the length direction of the water filter trough, and a spiral motor is provided at one end of the spiral extrusion sheet close to the processing box; one end of the water filter trough is located below the discharge door, and the other end is located above the funnel; the processing box and the water filter trough are both arranged in the water collection pool.

[0021] By adopting the above technical scheme, the treated mixed slurry enters the filter trough through the discharge gate, and is extruded, dehydrated and transmitted by the spiral extrusion plates. The spacing between the front section of the spiral extrusion plates is wide, and the spacing between the rear ends is narrow, thereby more fully draining the water in the mixed slurry, so that the solid feces residue after extrusion can contain less water. The water squeezed out by the spiral extrusion plates will be discharged from the filter trough and flow into the collection pool, thereby ensuring the efficiency of dry and wet separation.

[0022] Optionally, the dehydration assembly further comprises a blocking plate, which is slidably connected in the processing box and is located above the water filter hole, and a linear electric cylinder 2 is provided at one end of the blocking plate.

[0023] By adopting the above technical scheme, the bottom surface of the processing box is an inclined surface, which is convenient for the mixed slurry to enter the water filter trough after opening the discharge door. A water filter hole is provided on the inclined plate of the processing box. The aperture of the water filter hole is much smaller than the particle size of the solid matter in the mixed slurry. A sealing plate slidably connected above the water filter hole blocks the water filter hole to prevent gas leakage during the gas treatment process. When the gas treatment is completed, the sealing plate is slid open, and the water in the mixed slurry will flow from the water filter hole into the water collection tank, realizing preliminary solid-liquid separation, thereby avoiding the solids in the water filter trough from floating with the liquid and flowing directly into the water collection tank, effectively improving the collection efficiency of solid feces.

[0024] In summary, this application includes the following beneficial technical effects:

[0025] 1. By setting up two stirring tanks for waste collection and stirring treatment, the waste diversion is effectively realized, ensuring that the waste can be collected while stirring the waste. The waste gas treatment component is set above the treatment box because the density of odor and waste gas is smaller than that of air. Setting the waste gas treatment component above the treatment box is more convenient for collecting and treating waste gas and odor;

[0026] 2. The spacing of the spiral extrusion plates from large to small can effectively dehydrate the solid feces. At the same time, the coordinated use of the water filter holes and the sealing plates can more efficiently ensure the collection efficiency of the solid feces, and finally achieve the effective separation, treatment and collection of solid, liquid and gas;

[0027] 3. With the coordinated use of the extrusion plate and the mold, the feces can be squeezed into strips more efficiently, and then the spiral blade can be used to cut the feces into particles more quickly. Finally, the hot air motor is used to dry the feces into dry particles. The feces particles are dry, harmless and easy to use, which greatly improves the waste treatment efficiency and the utilization efficiency of feces. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Reference Figure 3The exhaust gas treatment component 12 includes an exhaust fan 121, an ion generator 122, an exhaust pipe 123 and an activated carbon layer 124. A partition plate 141 is welded to the upper half of the interior of the treatment box 14, and the exhaust fan 121 is installed on one side of the partition plate 141 by bolts.

The exhaust pipe 123 is welded to the top of the treatment box 14 and is located outside the treatment box 14. The activated carbon layer 124 is clamped in the exhaust pipe 123.

[0045] The bottom of the processing box 14 is an inclined plate, and the inclined plate gradually lowers from the side close to the stirring tank 111 to the side away from the stirring tank 111. On the processing box 14, a discharge door 142 is hinged at the lower end of the inclined plate, and a flip motor 143 is welded at the hinge of the discharge door 142. The flip motor 143 is used to control the opening and closing of the discharge door 142.

[0046] Reference Figure 3 The dehydration assembly 13 includes a spiral extrusion sheet 131, a water filter trough 132 and a water collection pool 133. One end of the water filter trough 132 is located below the discharge door 142 for receiving the mixture poured out from the discharge door 142. The spiral extrusion sheet 131 is installed in the water filter trough 132 along the length direction of the water filter trough 132 and is rotatably connected to the water filter trough 132. The spacing of the spiral extrusion sheets 131 gradually decreases from the end close to the treatment box 14 to the end away from the treatment box 14. A spiral motor is welded at the end of the spiral extrusion sheet 131 close to the treatment box 14. The treatment box 14 and the water filter trough 132 are both located in the water collection pool 133. A guide groove is opened at one end of the water collection pool 133 for collecting water in the water collection pool 133.

[0047] Reference Figure 3 and Figure 4 The granulation mechanism 2 includes a pelletizing assembly 21, a drying assembly 22 and a collecting box 23. A funnel 231 is integrally formed on the top of the collecting box 23. The pelletizing assembly 21 is installed in the collecting box 23 and is located directly below the funnel 231. The drying assembly 22 is installed below the pellet outlet end of the pelletizing assembly 21; the funnel 231 is located directly below the end of the water filter trough 132 away from the processing box 14, and is used to receive the fecal residue squeezed and dehydrated by the spiral extrusion sheet 131.

[0048] Reference Figure 4The pelletizing assembly 21 includes a linear electric cylinder 211, an extrusion plate 212, a mold plate 213, a rotating blade 214 and a cutting motor 215. The linear electric cylinder 211 is welded on the collecting box 23 and is located directly below the funnel 231. Its pushing end is horizontally away from the end of the processing mechanism 1. The extrusion plate 212 is welded on the pushing end of the linear electric cylinder 211. The mold plate 213 is welded in the collecting box 23 and is located at the far end of the pushing direction of the linear electric cylinder 211. The driving end of the cutting motor 215 is welded to the spiral blade. The spiral blade is located at the end of the mold plate 213 away from the extrusion plate 212 and is closely arranged with the mold plate 213.

[0049] Reference Figure 4 The drying component 22 includes an isolation net 221 and a hot air motor 222. There are two groups of hot air motors 222, which are installed at the bottom of the collection box 23 by bolts and are located below the rotating blade 214. The isolation net 221 is welded between the hot air motor 222 and the spiral blade. On the collection box 23, a collection door 232 is installed on one side of the isolation net 221, and the top edge of the collection door 232 is hinged to the collection box 23.

[0050] The present invention relates to a principle: when waste is processed, the waste flows in through the main pipe 1131. When the waste enters the branch pipe 1132, one of the valves 11321 is closed and the other valve 11321 is opened for collection. When a stirring tank 111 collects a sufficient amount of waste, the valve 11321 is closed and the valve 11321 of another stirring tank 111 is opened for collection, so that the waste can be continuously collected when the stirring tank 111 is stirring.

[0051] Before stirring the waste, add microorganisms for treating harmful substances into the stirring tank 111, then close the valve 11321 and start stirring. Drive the driving gear 1142 through the driving motor 1141, and then drive the driven gear 1143 to drive the stirring paddle 112 to rotate and stir the waste. During the stirring process, the stirring tank 111 is in a sealed state, which prevents odor leakage while providing a better oxygen-free environment for anaerobic microorganisms. After stirring for a specified time, a mixed slurry is formed.

[0052] The mixed slurry is pumped from the stirring tank 111 into the treatment box 14 by the vacuum pump 116. The odor dispersion area of ​​the fully stirred mixed slurry is large at this time. Therefore, the gas of the mixed slurry is pumped into the ion generator 122 by turning on the exhaust fan 121. A large number of positive and negative ions are generated by the ion generator 122 and combined with ions in the gas to remove the odor and harmful components. The treated gas is discharged through the exhaust pipe 123, and will be further adsorbed by the activated carbon layer 124 in the exhaust pipe 123, so that the odor of the discharged gas is greatly reduced, which plays a certain degree of protection role in the environment.

[0053] When the gas treatment of the mixed slurry is completed, the discharge door 142 is opened by turning the motor 143, and the mixed slurry will flow into the filter trough 132 from the inclined surface. The spiral extrusion plate 131 is driven by the spiral motor to rotate to separate the water and solid in the mixed slurry. The separated water will flow into the collecting pool 133, and the solid feces residue squeezed by the spiral extrusion plate 131 will fall onto the funnel 231 and then enter the collection box 23.

[0054] When the feces enter the collecting box 23, the linear electric cylinder 211 will drive the extrusion plate 212 to push the feces toward the mold plate 213 until the feces pass through the mold plate 213 to form a long strip, and then the cutting motor 215 drives the rotating blade 214 to cut it into particles, and finally it falls onto the isolation net 221, and then the hot air motor 222 is turned on to heat and dry the feces particles. The operator can pull the collecting door 232 at the bottom of the collecting door 232 to open the collecting box 23. The dried feces particles can be collected from the collecting door 232 and used directly as fertilizer, which effectively improves the processing efficiency and utilization rate of the feces.

[0055] In this embodiment, the mesh sizes of the water filter trough 132 and the isolation net 221 are much smaller than the particle size of the solid feces residue.

[0056] Embodiment 2:

[0057] Reference Figure 3 On the basis of the first embodiment, a water filter hole 144 is opened on the inclined plate, and a sealing plate 134 is slidably connected to the top of the inclined plate. A linear electric cylinder 135 is welded to one end of the sealing plate 134, and the sealing plate 134 can be driven by the linear electric cylinder 135 to seal and open the water filter hole 144.

[0058] In this embodiment, the diameter of the water filter hole 144 is much smaller than the particle size of the solid feces residue.

[0059] Embodiment three:

[0060] On the basis of the first embodiment, an incinerator can be set behind the drying component 22. In the embodiment of the present application, the granular feces in the drying component 22 can be transferred to the incinerator, and burned into ashes in the incinerator. The incinerated feces ashes can also be used as crop fertilizer. Specifically, a conveyor belt can be set on one side of the collection door 232 of the drying component 22, one end of the conveyor belt is located below the collection door, and the other end is located above the feed port of the incinerator. The granular feces are transferred from the isolation net 221 to the collection box 23 and directly fall on the conveyor belt after passing through the collection door 232. The conveyor belt transports the feces to the incinerator. The feces can be burned regularly or continuously in the incinerator. Among them, how to transfer the granular feces in the collection box 23 to the incinerator can be transferred manually or by a conveying mechanism. In addition, the incinerator can also be set to be movable. When collecting feces, the incinerator is close to the collection door 232 for easy collection. When the feces need to be incinerated, the incinerator is far away from the collection box 23.

[0061] The present invention relates to the principle: when the odor treatment of the mixed slurry is completed, the sealing plate 134 can be opened by the linear electric cylinder 135, and the water in the mixed slurry is discharged through the filter hole, and then the discharge door 142 is opened to allow the solids in the mixture to flow into the filter trough 132. This operation can effectively prevent a large amount of mixed slurry from entering the filter trough 132 and taking away a large amount of solid feces during the drainage process. The above is only a specific implementation method of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present application should be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
