Description

Technical Field

[0001] The utility model relates to a fecal sewage treatment device, in particular to a multi-purpose organic waste insect treatment device and system. Background Art

[0002] In people's production and life, organic wastes such as fecal sewage and kitchen waste are constantly generated, including human feces, animal feces, food waste, etc. If these organic wastes are not properly treated, they will cause serious environmental and odor pollution, and at the same time, it is also a waste of resources. Treating them with saprophagous insects is a good choice, which can not only solve environmental protection problems but also turn waste into treasure. However, most of the existing processes are centralized treatment, with many links and high costs. If there is an insect treatment device that can process organic wastes nearby, in a small-scale and intelligent manner, it will greatly reduce the collection and transportation costs, and at the same time reduce the pollution caused during transportation. Therefore, researching and developing an organic waste insect treatment equipment and technology that can be nearby, small-scale and intelligent is of great significance for the treatment of urban fecal sewage and food waste as well as rural small-scale scattered breeding fecal sewage.

[0003] The treatment of fecal sewage has certain particularities. Fecal sewage is mainly discharged into septic tanks. As an intercepting feces facility set to avoid blockage of drainage pipes, septic tanks play an active role in intercepting and precipitating large particulate impurities in sewage, preventing blockage of sewage pipes, and environmental protection. Although septic tanks are commonly used in urban residential areas, their treatment process is simple, unable to completely remove various germs and foul odors in fecal sewage residues, and it is also very difficult to recycle the remaining residues. The fecal sewage residues intercepted in septic tanks are generally transported to a fecal sewage treatment plant by a manure suction truck for centralized treatment. The above method has a complex treatment process and high costs. Data shows that making feces into agricultural fertilizers not only contains the nutrients required by crops but also contains nitrogen-fixing, phosphorus-dissolving, and potassium-dissolving functional bacteria, which can prevent soil compaction, cultivate soil fertility, improve grain quality, and increase crop yields, having advantages that cannot be compared with chemical fertilizers. If urban fecal sewage can be reasonably treated and utilized, its resource benefits are significant. Therefore, researching urban fecal sewage treatment is of great significance.

Detailed implementation mode

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] Embodiment 1

[0042] As Figure 1 and 2 shown, a multi-purpose organic waste insect treatment device includes a bracket 9 and a box body 14, and the box body 14 is installed on the bracket 9. The function of the bracket 9 is to fix and install the box body 14, and different materials can be selected according to the actual situation. Generally, I-beams are used for manufacturing, and mobile mechanisms such as universal wheels can be selected according to needs. In this embodiment, no mobile mechanism is provided.

[0043] The box body 14 is the main component for insect breeding. Generally, a square box body or a circular box body is used. In this embodiment, a square box body is used. The box body 14 is generally made of corrosion-resistant materials such as stainless steel and tempered plastic. In this embodiment, stainless steel is used.

[0044] A plurality of discharging mechanisms are provided at the bottom of the box body 14. A first air inlet 10 is provided at the lower part of the discharging mechanism. A worm discharging mechanism is provided at the top of the box body 14. The box body 14 is successively provided with a breeding layer 2, a buffer layer 3 and a dry material layer 4 from top to bottom. The heights of the buffer layer 3 and the dry material layer 4 can ensure that the temperature of the breeding layer 2 during air drying does not affect the normal growth or survival of insects. There is no clear dividing line between the breeding layer 2, the buffer layer 3 and the dry material layer 4 in the box body 14, which is determined by the amount of material to be processed and the size of the equipment. The main thing is to ensure that the hot air introduced from the dry material layer 4 will not have a great impact on the life or survival of the insects in the breeding layer 2 during drying and will not cause the death of insects.

[0045] The discharging mechanism includes a plurality of rotating shafts 6 connected to each other and a stirring mechanism. The rotating shafts 6 are installed with the stirring mechanism. The stirring mechanism includes stirring teeth. The stirring teeth on adjacent rotating shafts are arranged staggeredly. When the staggeredly arranged stirring teeth are stationary, they form a supporting mechanism to prevent the material from leaking out. The rotating shafts are connected to a power mechanism. The rotating shafts 6 are connected to each other through sprockets 30 or gears 5.

[0046] As Figure 5 shown, the stirring mechanism includes a main shaft 29. The main shaft 29 is installed with the rotating shafts. A plurality of stirring teeth are arranged staggeredly on the main shaft 29.

[0047] In this embodiment, a gear 5 is provided on each rotating shaft 6, and the rotating shafts 6 are connected together through the meshing of the gears 5. The number of rotating shafts 6 is not less than 2, and the specific number is set according to the size of the box body 14. In this embodiment, 12 rotating shafts 6 are adopted. The stirring teeth are generally circular stirring teeth 15 or square stirring teeth 36. Circular stirring teeth are adopted in this embodiment. The above shapes can play a better sealing and supporting role to prevent the feces from falling. Of course, they can be set as round needle-shaped stirring teeth or square needle-shaped stirring teeth, but the needle part of the needle-shaped stirring teeth should be as short as possible so that there will be no feces leakage problem when the rotating shafts 6 are stationary.

[0048] The discharging mechanism can be set according to the actual situation. Generally, one discharging mechanism is adopted. As Figure 6 shown, if the material humidity is relatively high and the amount of material is relatively large, resulting in serious compression of the material and affecting the air permeability, then multiple discharging mechanisms can be set according to the actual situation, and a diversion port is provided between the two discharging mechanisms to quickly air-dry the material between the two discharging mechanisms. Figure 6 Two discharging mechanisms are provided in

[0049] When two discharging mechanisms are set, a third air inlet can be provided between the two discharging mechanisms for sending in dry hot air to perform a drying operation on the material between the two discharging mechanisms.

[0050] The function of the power mechanism is to drive the gears on the rotating shaft to rotate. Any power mechanism that can perform the above function is acceptable. In this embodiment, the power mechanism uses a motor 8 and a pulley. The pulley 7 is installed on a rotating shaft 6. The pulley 7 is connected to the motor through a belt. The gears 5 on the rotating shaft mesh with each other.

[0051] The main function of the insect discharging mechanism is to collect mature insects according to the living habits of insects. It can be set to different structures according to the habits of different insects. The scavenging insects (such as black soldier fly larvae, etc.) bred in this utility model generally climb out of the feed and look for a dry and quiet environment to pupate in the later stage of maturity. Therefore, the insect discharging mechanism of this utility model includes a worm collecting groove 1 arranged at the top of the box body 14. There are insect discharging holes on the worm collecting groove 1. The worm collecting groove 1 can be arranged around the box body 14, or can be arranged at one or several places, as long as it can enable insects to climb in for collection. A collecting pipe 13 can be arranged below the insect discharging holes to facilitate the collection of insects.

[0052] The bottom of the box body 14 has a very good sealing effect under the interaction of the discharging mechanism, the dry material layer 4, and the buffer layer 3. However, in order to make better use of the dry hot air, a discharging hopper 11 can be arranged below the discharging mechanism. There is a discharging valve 12 on the discharging hopper 11. The first air inlet 10 is arranged on the discharging hopper 11.

[0053] The device of this embodiment can be used for insect breeding. After the organic waste suitable for insects is processed and crushed, materials with different heights are filled according to the heights of the buffer layer 3 and the dry material layer 4 to ensure that the temperature of the breeding layer 2 during air drying does not affect the normal growth or survival of insects for breeding.

[0054] During the breeding process, new raw materials are continuously added. Mature insects climb out of the box body 14 and enter the worm collecting groove 1 for collection. When the insect feces in the box body 14 reach a certain thickness, dry hot air is introduced through the first air inlet 10. The dry hot air sequentially passes through the dry material layer 4, the buffer layer 3, and the breeding layer 2 to dry the insect feces in the dry material layer 4 to make it reach the discharging standard. During the drying process, the dry hot air goes from bottom to top, the temperature continuously decreases, and the humidity continuously increases. In this way, when it reaches the breeding layer 2, it will not cause large fluctuations in the temperature of the raw materials in the breeding layer 2, and it still meets the requirements for insect growth or survival. Then the discharging mechanism is started to discharge the insect feces in the dry material layer 4 as raw materials for organic fertilizers. The insect feces in the buffer layer 3 descend to the dry material layer 4 under the action of gravity to fill the dry material layer 4. The insect feces at the bottom of the breeding layer 2 descend to become the buffer layer 3. In this way, there is space in the breeding layer 2 for adding new raw materials, realizing continuous feeding, breeding, insect discharging, and feces discharging, cyclic operation, and can also realize automated production.

[0055] The device of this embodiment can not only be used for insect breeding, but also for separating insects and insect feces after other insect farming. The usage method is as follows:

[0056] 1. Import the materials after insect farming into the box body 14 of the present utility model;

[0057] 2. Pass in dry hot air (it is also possible to let the materials ferment and generate heat by themselves or other heating methods);

[0058] 3. The temperature of the materials rises from bottom to top;

[0059] 4. The insects move upward;

[0060] 5. The insects enter the insect collection tank, start the discharging mechanism, and discharge the insect feces in the dry material layer 4;

[0061] 6. Continuously input the insects and insect feces to be separated, and continuously perform operations such as separation of insect feces and insects, air drying of insect feces, and discharging.

[0062] Embodiment 2

[0063] As Figure 3 shown, a multi-purpose organic waste insect treatment device has a structure basically similar to that of the embodiment. The difference is that: a sealing cover 17 can be provided at the upper part of the box body 14 according to different breeding environments or insects, which is used to seal the box body 14 to reduce environmental pollution caused by exhaust gas generated during the breeding process. An insect input port 18, a feeding port 28 (provided opposite to the insect input port 18, not shown in the figure), and an exhaust port 16 are provided on the sealing cover 17. Heating mechanisms, light supplement mechanisms, trace element feeding mechanisms, etc. can be set according to different living habits of insects.

[0064] A second air inlet 19 or an exhaust port can be provided on the box body 14 according to actual needs. Setting an exhaust port on the box body can effectively discharge the air with excessive humidity in time to avoid affecting the upper layer of materials.

[0065] Setting two air inlets is more conducive to precise control of the breeding environment. The second air inlet 19 is used for ventilation, oxygen supply, and heat exchange control during the breeding process; the first air inlet 10 is used to pass in dry hot air for air drying and discharging feces during the air drying process. Of course, the first air inlet 10 can also be used for ventilation, oxygen supply, and heat exchange operations during the breeding process.

[0066] During the insect breeding process, the temperature generally needs to be controlled. Therefore, heat insulation layers are provided on the box body 14, the discharge hopper 11, and the sealing cover 17, which can effectively improve the utilization rate of heat sources and reduce the operating cost.

[0067] Embodiment 3

[0068] As Figure 4As shown in the figure, a multi - purpose organic waste insect treatment system includes a multi - purpose organic waste insect treatment device, a deodorization mechanism 21, an automatic insect feeding mechanism 20, a feeding mechanism 24, a air supply mechanism 27, a temperature control mechanism, a weighing and insect collection mechanism 22 and a control system.

[0069] The structure of the multi - purpose organic waste insect treatment device is the same as that in Embodiment 2 and will not be described again.

[0070] The deodorization mechanism 21 is connected to the exhaust port 16, the automatic insect feeding mechanism 20 is connected to the insect feeding port 18, the feeding mechanism 24 is connected to the feeding port 28, the air supply mechanism 27 is respectively connected to the first air inlet 10 and the second air inlet 19. The temperature control system includes a temperature and humidity sensor 23, and the temperature and humidity sensor 23 is arranged on the breeding layer 2, the buffer layer 3 and / or the manure outlet layer of the box body 14. The weighing and insect collection mechanism 22 is arranged at the lower part of the insect collection pipe 13. The discharge mechanism, the deodorization mechanism 21, the automatic insect feeding mechanism 20, the feeding mechanism 24, the air supply mechanism 27, the temperature control mechanism and the weighing and insect collection mechanism 22 are respectively connected to the control system.

[0071] The deodorization mechanism 21 is mainly used for the purification treatment of waste gas during the breeding process. Just select a suitable deodorization mechanism 21 according to different raw materials and insects. The deodorization mechanism 21 belongs to conventional equipment and will not be described in detail.

[0072] The automatic insect feeding mechanism 20 is mainly used for the feeding of insect larvae. Just select a suitable device according to the habits of different insects. If breeding black soldier fly larvae or similar insects, a insect feeding system for realizing multi - day / multi - time automatic feeding of black soldier fly small larvae in CN110150235A can be selected. For the specific structure, refer to this patent and will not be described in detail.

[0073] The feeding mechanism 24 is mainly used for the preliminary treatment of raw materials. According to the actual situation, it can be set to different functions. The feeding mechanism 24 in this embodiment includes a hopper 25 and a crushing and feeding mechanism 26. In this embodiment, a spiral feeder is used for the feeding mechanism, and a solid - liquid separation mechanism can also be set according to needs. The separated solid is used as raw material for feeding insects.

[0074] The air supply mechanism 27 mainly provides dry hot air for air drying and controls the temperature, humidity and dissolved oxygen in the breeding environment. A blower with heating function can be used, or two blowers can be used. One is used to provide dry hot air, and the other is used for the control of the breeding environment. The blower for providing dry hot air is connected to the first air inlet 10, and the blower for controlling the breeding environment is connected to the second air inlet 19. Of course, when the temperature and humidity of the ambient air are appropriate, only one blower for controlling the breeding environment needs to be set to achieve breeding and air drying, and a dry hot air blower is not required.

[0075] The temperature control mechanism is used for detecting the temperature and humidity in the breeding and air-drying environment. Generally, temperature and humidity sensors are adopted. Usually, two temperature and humidity sensors are set. One is set in the dry material layer 4 for detecting the temperature and humidity of the excrement, and the other is set in the breeding layer 2 for detecting the temperature and humidity of the breeding environment.

[0076] The weighing and insect collecting mechanism 22 is mainly used for detecting the weight of the insects discharged, and is used as the control index for discharging and insect feeding.

[0077] The system of the present utility model can also be provided with a solar power supply system for providing the power for the system operation.

[0078] The control system generally adopts a programmable single-chip microcomputer for the overall monitoring and control of the system. This belongs to common knowledge and will not be described in detail.

[0079] Embodiment 4

[0080] An integrated continuous insect breeding, air-drying and excrement discharging method adopts the processing system of Embodiment 3, and comprises the following steps:

[0081] (1) Put dry insect excrement or other dry substrates into the box body 14 to form a buffer layer 3 and a dry material layer 4. The heights of the buffer layer 3 and the dry material layer 4 are adjusted according to the overall height of the box body 14 and the weight of the feed, so that the heights of the buffer layer 3 and the dry material layer 4 can ensure that the temperature of the breeding layer 2 during air-drying does not affect the normal growth or survival of the insects;

[0082] (2) Connect the material feeding pipe with the feeding mechanism. The solid part is used as the feed for raising insects through the screening mechanism and enters the box body 14 to form a feeding layer, and the liquid part returns to the material feeding pipe through the pipeline;

[0083] (3) Put saprophagous insects of different instars into the box body 14. The input ratio is determined according to the weight of the solid part filtered by the material feeding pipe every day, so as to ensure that the input saprophagous insects convert all the fecal sewage entering the box body 14 within one day;

[0084] (4) During the breeding process, the temperature and humidity sensor 23 detects the temperature of the breeding environment and controls the temperature and humidity of the breeding environment. The feeding mechanism constantly sends the screened solid part into the box body 14, and the breeding waste gas is discharged after being treated by the deodorizing mechanism 21;

[0085] (5) The mature insects enter the weighing and insect collecting mechanism 22 through the insect collecting tank 1 and the insect discharging hole for weighing and collecting;

[0086] (6) The control system controls the automatic insect feeding mechanism 20 to input new larvae according to the collected insect weight, and controls the discharging mechanism to discharge materials. When discharging, according to the data of the temperature and humidity sensor 23, when the humidity does not meet the discharging requirement, the air supply mechanism 27 is started to blow dry hot air to make it reach the discharging standard;

[0087] (7) Repeat the steps of (5) and (6) to achieve continuous treatment of fecal sewage.

[0088] Example 5

[0089] The multi-purpose organic waste insect treatment system of the present utility model can be used not only as a mechanism integrating breeding, air drying and discharging, but also as a separate insect discharging and air drying mechanism. The specific structure is as follows:

[0090] As Figures 7 - 10 shown, an organic waste insect discharging mechanism includes a bracket 9 and a box body 14, and the box body 14 is installed on the bracket 9. A plurality of discharging mechanisms are arranged at the bottom of the box body 14, and a discharging hopper is arranged below the discharging mechanism. A sealing cover 17 and an insect discharging mechanism are arranged at the top of the box body 14, and a feeding port 28 is arranged on the sealing cover 17.

[0091] The discharging mechanism includes a plurality of rotating shafts 6 connected to each other and a stirring mechanism. The rotating shafts 6 are installed together with the stirring mechanism. The stirring mechanism includes stirring teeth, and the stirring teeth on adjacent rotating shafts are arranged staggeredly. The staggeredly arranged stirring teeth form a supporting mechanism when stationary to prevent materials from leaking out. The rotating shafts are connected to a power mechanism. The rotating shafts 6 are connected to each other through a sprocket 30 or a driven gear 5.

[0092] The power mechanism in this embodiment includes a motor and a sprocket 30. The sprocket 30 is installed on a rotating shaft, and the motor is connected to the sprocket 30 through a chain 31.

[0093] The stirring mechanism includes a plurality of thorn shaft plates 34 with stirring teeth. Both ends of the thorn shaft plate 34 are fixed to the rotating shaft 6 through a connecting portion 35. In this embodiment, there are two thorn shaft plates 34, and the stirring teeth on the thorn shaft plate 34 are square stirring teeth 36. The thorn shaft plate 34 in this embodiment is formed by stamping a square stirring tooth 36 on a steel plate, which is simple in manufacturing and low in cost compared with welding stirring teeth on the main shaft 29.

[0094] The insect discharging mechanism includes a worm collecting groove 1 arranged at the top of the box body, and a worm collecting pipe 13 is arranged on the worm collecting groove 1.

[0095] The described insect discharging mechanism further includes an inclined insect guiding corrugated plate 32 arranged inside the box body, and the insect guiding corrugated plate 32 is communicated with the insect collecting groove 1. The insect guiding corrugated plate 32 is a plate with corrugated grooves on one side. Using the above mechanism is beneficial for mature larvae to quickly climb out of the box body and enter the insect collecting groove, improving the insect collecting efficiency. A heating mechanism 33 is arranged inside the box body. The heating mechanism 33 generally adopts an electric heating mechanism or a water heating mechanism. In this embodiment, a water heating mechanism is adopted. Setting the heating mechanism makes the temperature rise more quickly compared with ventilation heating during breeding, which is beneficial for quickly separating mature larvae.

[0096] The operation process of this embodiment:

[0097] Use the heating mechanism to raise the temperature inside the box body to the set temperature, and then add the materials after feeding through the feeding port 28. At high temperature, the insects in the materials climb into the insect collecting groove through the insect guiding corrugated plate and are finally collected and separated through the insect collecting pipe. The insect sand accumulates inside the box body. When the insect sand inside the box body accumulates to a certain height, start the power mechanism to drive the rotation of the rotating shaft, discharge the insect sand inside the box body through the discharge hopper, and at the same time continuously add new materials, control the rotation speed of the power mechanism to realize continuous addition of the mixture and continuous discharge of the insect sand, realizing continuous operation of insect separation and insect sand discharge in the mixture, effectively improving the separation efficiency.

[0098] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
