Description

Technical Field

[0001] This invention relates to the field of waste treatment equipment, specifically a process and equipment for decomposing kitchen waste. Background Technology

[0002] Kitchen waste comes from leftover food, vegetable scraps, fruit peels, eggshells, tea dregs, etc., generated in restaurants, households, and collective units, and is mainly composed of easily decomposable organic matter.

[0003] These organic substances can be processed by both aerobic and anaerobic bacteria, but the specific substances reacted by the two types of bacteria and the reaction environment are different. Generally, soluble organic substances, such as proteins, carbohydrates, and fatty acids, can be utilized by aerobic bacteria, while anaerobic bacteria can degrade a variety of organic substances, including proteins, lipids, carbohydrates, and alcohols.

[0004] This means that existing waste treatment processes often require the use of two or more separate devices for decomposition. After processing with one strain of bacteria, the waste needs to be transferred to the next strain for further decomposition, which is quite cumbersome. Furthermore, if the substrate produced by one strain of bacteria is not mixed sufficiently or evenly with the second strain of bacteria during the next bacterial reaction, the reaction between the waste and the second strain of bacteria may be incomplete.

[0005] Meanwhile, users typically use a mixing machine to process kitchen waste. This machine contains a mixing component to mix the waste and bacteria, allowing them to react. In a typical mixing machine, the rotating mixing shaft drives the mixing rod on the shaft to rotate, and the claw plates on the mixing rod mix the materials in the bin. However, the mixing capacity of this mixing method needs improvement. Therefore, existing technologies add a bevel gear inside the mixing shaft to connect with the mixing rod, so that the rotating shaft drives the mixing rod to rotate, making the materials churn more violently and increasing the mixing degree. However, in this form, the mixing rod is constantly rotating, so the materials all tumble in the direction of rotation. Only when the material reaches a certain level will it have a natural force to fall back to the previously tumbled area for the next tumbling. In the middle and later stages of the reaction, the material decreases, and at this point, the material tends to accumulate to one side, requiring conventional mixing methods to agitate the material and create a larger disturbance across its cross-section.

[0006] However, in the existing technology, the stirring rod and the added gear are always meshed, which makes it impossible for the stirring rod to drive the claw plate to be in a normal stirring state on its own, that is, the material to be disturbed over a large range in the cross-section. Summary of the Invention

[0007] To address the above problems, this invention provides a process and equipment for decomposing kitchen waste.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a kitchen waste decomposition process and equipment, comprising a body and a reaction chamber connected to the body, which holds anaerobic bacteria substrate and the waste to be processed. The reaction chamber is equipped with a stirring shaft that is driven by a motor. The body includes a control box, an air inlet / outlet assembly, an oxygen generator, a heater, and a humidity control device. The air inlet / outlet assembly includes an intake fan and an exhaust fan. The stirring shaft is equipped with stirring claws, each claw comprising a claw rod with a claw plate at the end and a transmission component connected to the claw rod. The stirring shaft contains a guide component, which includes a fixed gear. The transmission component of the claw rod engages with the fixed gear of the guide component within the stirring shaft.

[0009] Furthermore, the guide includes a fixed shaft and fixed teeth mounted on the fixed shaft. The fixed shaft retains the freedom to move along its axis within the reaction chamber and the stirring shaft. The fixed shaft is connected to the pusher. The fixed teeth are provided with two fixed gears with facing tooth surfaces at positions corresponding to the stirring claw.

[0010] Furthermore, the transmission component connected to the claw rod includes a transmission gear. The claw rod and the transmission gear are detachably mounted inside the casing via a bushing. The casing is detachably mounted on the stirring shaft. The transmission gear is located between two fixed gears inside the stirring shaft.

[0011] Furthermore, a positioning disc is provided inside the tube shell, and a limiting member is provided on the claw rod inside the tube shell to abut against the positioning disc. A spring is provided between the end of the positioning disc that does not abut against the limiting member and the inner wall of the tube shell.

[0012] Furthermore, the positioning disk is provided with a positioning groove, which is recessed in the positioning disk. The limiting member includes a support arm fixed on the claw bar and a roller installed at the end of the support arm. The roller abuts against the bottom end of the recess in the positioning groove. When the roller abuts against the bottom end of the recess in the positioning groove, the length direction of the claw plate is parallel to the stirring shaft.

[0013] Furthermore, the positioning disk is also provided with an annular release groove, which is connected to the outer end of the positioning groove. The support arm and the claw rod are hinged together, and a spring is provided between the support arm and the claw rod.

[0014] Furthermore, the roller is surrounded by a plurality of guide wheels with axes perpendicular to the roller. The release groove is annular in shape on the side of a frustum. The inner edge of the release groove is connected to the positioning groove. The distance between the outer edge of the release groove and the limiting member is smaller than the distance between the inner edge of the release groove and the limiting member.

[0015] A process for decomposing kitchen waste includes the following steps:

[0016] S1: Prepare a mixture of aerobic and anaerobic bacteria, and mix the mixture of aerobic and anaerobic bacteria with the bioactive medium base material and put it into the reaction chamber;

[0017] S2: The airflow within the reaction chamber is maintained at 20-60m using the control box. 3 / h, air pressure 0.2-0.6MPa, temperature 25-60 degrees Celsius and humidity 70-95%;

[0018] S3: Put the waste into the reaction chamber and start the stirring shaft to drive the stirring claws to fully mix the waste with the aerobic and anaerobic bacteria mixture;

[0019] S4: During the stirring process in step S3, the oxygen environment in the reaction chamber is switched between aerobic and anaerobic or low-oxygen environments to activate different strains for reaction. The duration of the aerobic environment is 5-15 minutes, and the duration of the anaerobic or low-oxygen environment is 5-15 minutes.

[0020] S5: Waste gas is discharged during the reaction, and materials and waste gas are discharged after the reaction is completed.

[0021] Furthermore, in step S2, the control box controls the air inlet and outlet components, the heater, and the humidity device to control the airflow, air pressure, temperature, and humidity environment inside the reaction chamber. The air inlet and outlet components include an air intake fan and an exhaust fan. In step S4, the control box controls the air intake fan, the exhaust fan, and the oxygen generator to control the oxygen environment.

[0022] Furthermore, during the stirring process in step S3, the guide member drives the claw rod to rotate when the stirring shaft rotates, so that the claw rod can turn the material around an axis perpendicular to the axis of the stirring shaft while turning the material around the axis of the stirring shaft.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] This invention decomposes kitchen waste by mixing aerobic and anaerobic bacteria in the same reaction chamber. It utilizes an intake fan, exhaust fan, and oxygen generator to control the oxygen environment, switching between aerobic, anaerobic, and low-oxygen environments within the reaction chamber to activate different bacterial strains for reaction. Simultaneously, the mixing component of this invention thoroughly mixes the materials, effectively decomposing kitchen waste within the same equipment. This eliminates the need for waste sorting or multiple processing steps, reducing the investment in processes and equipment.

[0025] This invention utilizes a movable gear that meshes with a claw lever, causing the claw lever to rotate the claw plate. This allows for better material agitation during the early and middle stages of the decomposition reaction. An internal automatic reset component is also included. When the claw lever rotates, the roller of the limiting component runs on an annular release groove, thus eliminating the limiting effect. When rotation is no longer needed, the inclined release groove moves the roller towards the inner positioning groove, returning it to the positioning groove. This automatically resets the relative position of the claw lever and the positioning plate to their state before rotation, allowing for subsequent normal stirring. This enables diverse stirring methods and allows for suitable stirring modes during the later stages of the decomposition reaction using normal stirring. Attached Figure Description

[0040] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Example: Figures 1-8 As shown, the present invention provides a process and equipment for decomposing kitchen waste;

[0042] Among them, such as Figure 1-3 As shown, a kitchen waste decomposition device includes a body 1 and a reaction chamber 2 connected to the body 1, which holds anaerobic bacteria substrate and the waste to be processed. The reaction chamber 2 is equipped with a stirring shaft 3 that is driven by a motor 16. The body 1 is equipped with a control box 11, an air inlet / outlet assembly, an oxygen generator 13, a heater 15, and a humidity device 17. The air inlet / outlet assembly includes an air intake fan 12 and an exhaust fan 14. The stirring shaft 3 is equipped with stirring claws 4, which include claw rods 42 with claw plates at the ends and a transmission component connected to the claw rods 42. The stirring shaft 3 is equipped with a guide component 5, which includes a fixed gear 52. The transmission component of the claw rods 42 engages with the fixed gear 52 of the guide component 5 within the stirring shaft 3. When the stirring shaft 3 rotates, the transmission component of the claw rods 42 meshes with the fixed gear 52 of the fixed guide component 5, thereby driving the claw rods 42 to rotate and causing the claw plates to rotate and flip.

[0043] Not only that, such as Figure 4 , 5As shown, in this embodiment, the guide 5 specifically includes a fixed shaft 51 and fixed teeth mounted on the fixed shaft 51. The fixed shaft 51 retains the freedom to move along its axis within the reaction chamber 2 and the stirring shaft 3. It is known that the fixed shaft 51 will not rotate around the axis within the stirring shaft 3. The fixed shaft 51 is connected to the pusher 6, which drives the fixed shaft 51 to translate within the stirring shaft 3. As those skilled in the art know, the pusher 6 is fixed to the outside of the reaction chamber 2 housing to push and pull the fixed shaft 51 within the stirring shaft 3. It is also known that the pusher 6 can be a cylinder, hydraulic cylinder, or electric push rod, as long as it achieves the push and pull function. The fixed teeth have two fixed gears 52 with facing tooth surfaces at positions corresponding to the stirring claw 4. During use, the pusher 6 can drive the fixed shaft 51 to make different fixed gears 52 mesh with the transmission components of the claw rod 42, so that when the stirring shaft 3 rotates in one direction, the claw rod 42 can rotate in different directions.

[0044] Moreover, such as Figure 4 , 5 As shown, for the stirring claw 4, specifically, the transmission component connected to the claw rod 42 includes a transmission gear 43. Since the claw rod 42 is perpendicular to the axis of the stirring shaft 3, as those skilled in the art will know, the transmission gear 43 and the fixed gear 52 can be bevel gears. The claw rod 42 and the transmission gear 43 are detachably installed in the tube shell 41 through the bushing 44. The tube shell 41 is detachably installed on the stirring shaft 3. For installation, an interface tube 3a for nesting with the tube shell 41 is welded on the stirring shaft 3. The transmission gear 43 engages with the fixed gear 52 in the stirring shaft 3.

[0045] At the same time, such as Figure 4 , 5 As shown, a positioning disk 46 is provided inside the shell 41. A limiting member 45 is provided on the claw rod 42 inside the shell 41, which abuts against the positioning disk 46. A spring 47 is provided between the end of the positioning disk 46 that does not abut against the limiting member 45 and the inner wall of the shell 41. Specifically, the positioning disk 46 is provided with a positioning groove 46a. The positioning groove 46a is recessed on the positioning disk 46, and there are two of them. The two recessed positioning grooves 46a are symmetrical to each other and are connected in a wave-shaped transition. The limiting member 45 includes a support arm 451 fixed on the claw rod 42 and a roller 452 installed at the end of the support arm 451. The roller 452 abuts against the bottom end of the recess in the positioning groove 46a. At this time, that is, when the roller 452 abuts against the bottom end of the recess in the positioning groove 46a, the length direction of the claw plate is parallel to the stirring shaft 3, that is, the claw plate has the largest cross-sectional area when it rotates around the stirring shaft 3.

[0046] In this embodiment, as Figure 6 , 7As shown, the positioning disk 46 is also provided with an annular release groove 46b, which is connected to the outer end of the positioning groove 46a. The support arm 451 is hinged to the claw rod 42. A spring 47 is provided between the support arm 451 and the claw rod 42. The spring 47 provides a spring force to drive the support arm 451 to swing outward, so that when the roller 452 rolls in the positioning groove 46a and passes through the intersection of the positioning groove 46a and the release groove 46b, the spring force of the spring 47 drives the support arm 451 to swing outward, so that the roller 452 transitions to the annular release groove 46b.

[0047] Meanwhile, in this embodiment, as Figure 8 As shown, a plurality of guide wheels 453 with axes perpendicular to the roller 452 are arranged around the roller 452, such as... Figure 6 , 7 As shown, the release groove 46b is annular in shape on the side of a frustum. The inner edge of the release groove 46b is connected to the positioning groove 46a. The distance between the outer edge of the release groove 46b and the limiting member 45 is smaller than the distance between the inner edge of the release groove 46b and the limiting member 45. When the claw bar 42 stops rotating, the inclined release groove 46b drives the roller 452 to move towards the inner positioning groove 46a, and drives the roller 452 back into the positioning groove 46a.

[0048] like Figure 9 As shown, a kitchen waste decomposition process includes the following steps:

[0049] S1: Prepare a mixture of aerobic and anaerobic bacteria. Mix the mixture of aerobic and anaerobic bacteria with the bioactive medium and place it in reaction chamber 2. The bioactive medium can be a product of fermentation of rice bran, tea oil meal, sesame meal and wheat bran, which provides certain nutrients for aerobic and anaerobic bacteria, enabling them to multiply rapidly.

[0050] S2: The environment inside the reaction chamber 2 is controlled by the control box 11 to maintain an airflow of 20-60 m3 / h, an air pressure of 0.2-0.6 MPa, a temperature of 25-60 degrees Celsius, and a humidity of 70-95%. Specifically, the control box 11 controls the air intake fan 12, the exhaust fan 14, the heater 15, and the humidity device 17 to control the airflow, air pressure, temperature, and humidity environment inside the reaction chamber 2. As is known, the humidity device 17 may include a humidity detector, a humidification device, and a dehumidification device, etc., which will not be described in detail here.

[0051] S3: Put the waste into the reaction chamber 2, start the stirring shaft 3 to drive the stirring claw 4 to fully mix the waste with the aerobic and anaerobic bacteria mixture;

[0052] During stirring, motor 16 drives stirring shaft 3 to rotate stirring claw 4. Claw plates on claw rod 42 rotate with stirring shaft 3 to stir the waste and bioactive medium substrate carrying aerobic and anaerobic bacteria in reaction chamber 2, making them evenly mixed. When claw plates on claw rod 42 are working, the material exerts resistance on the claw plates. This resistance cannot drive the positioning disk 46 and the limiting member 45 to move significantly, keeping the claw plates in a fixed state. After the claw plates perform planar stirring, pusher 6 drives fixed shaft 51 to translate within stirring shaft 3, so that one fixed gear 52 meshes with the transmission gear 43 of claw rod 42. This causes the claw rod 42 to rotate around the axis of claw rod 42 as stirring shaft 3 rotates around its axis, which has a better tumbling effect on the material. After tumbling in one direction, pusher 6 drives another fixed gear 52 to mesh with the transmission gear 43 of claw rod 42, so that claw rod 42 rotates around its axis in another direction, thereby achieving a better stirring effect in one stirring direction.

[0053] At the same time, when the transmission gear 43 drives the claw bar 42 to rotate, the roller 452 of the limiting member 45 runs in the positioning groove 46a on the positioning disk 46. The positioning disk 46 compresses the spring 47 to disengage from the limiting member 45, and the elastic force of the spring 47 drives the support arm 451 to swing outward, causing the roller 452 to transition to the annular release groove 46b. Thus, when the transmission gear 43 drives the claw bar 42 to rotate, the roller 452 of the limiting member 45 runs on the annular release groove 46b, thereby not producing a limiting effect.

[0054] When the pusher 6 drives the two fixed gears 52 to mesh with the transmission gear 43 in the middle of the gap, it pauses for a period of time, or when the rotation of the claw rod 42 is not required, the claw rod 42 moves to the top of the reaction chamber 2 and disengages from the material. At this time, the outer circumferential inertia generated by the rotation disappears, and the elastic force of the spring 47 drives the positioning plate 46 to press the support arm 451 and roller 452 of the limiting member 45. Since there is a guide wheel 453 on it, and it cooperates with the inclined release groove 46b, it drives the roller 452 to move in the direction of the inner positioning groove 46a, and drives the roller 452 back into the positioning groove 46a. At this time, the length direction of the claw plate is parallel to the stirring shaft 3, so that the claw plate returns to the state when it is not rotating, and the next normal stirring can be carried out.

[0055] As can be seen, in step S3, the guide member 5 drives the claw rod 42 to rotate when the stirring shaft 3 rotates, so that the claw rod 42 can turn the material around the axis of the stirring shaft 3 while turning the material around the axis of the stirring shaft 3, and can also turn the material around an axis perpendicular to the axis of the stirring shaft 3. After the rotation stops, the claw plate of the claw rod 42 can automatically reset. At the same time, the structure that drives the claw plate of the claw rod 42 to reset during the rotation will not cause great interference to the movement of the claw rod 42.

[0056] S4: During the stirring process in step S3, the control box 11 controls the air intake fan 12, the exhaust fan 14, and the oxygen generator 13 to control the oxygen environment, switching between aerobic and anaerobic or low-oxygen environments in the reaction chamber 2. The oxygen generator 13 produces oxygen to provide the oxygen required for the aerobic bacteria reaction in the reaction chamber 2. By turning off the oxygen generator 13 and using the air intake fan 12 to drive fresh air to replace the oxygen, and then using the exhaust fan 14 to remove the air inside the reaction chamber 2, the anaerobic bacteria can react, thereby activating different bacterial species to react. The aerobic environment lasts for 5-15 minutes, and the anaerobic or low-oxygen environment lasts for 5-15 minutes, thereby reacting and treating the waste. Generally, soluble organic matter, such as proteins, carbohydrates, fatty acids, etc., can be utilized by aerobic bacteria and converted into carbon dioxide, water, and microbial organisms, while anaerobic bacteria can degrade a variety of organic matter, including proteins, lipids, carbohydrates, alcohols, etc., as well as eggshells and bones, etc., so that the waste does not need to be sorted or processed in stages, and can be carried out in the same equipment.

[0057] S5: Waste gas is discharged during the reaction. The waste gas is treated by a deodorizer to meet emission standards or enters the heat energy cycle. After the reaction is completed, the treated materials and waste gas are discharged.

[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
