Description

Technical Field

[0001] The present invention relates to the technical field of domestic waste, and in particular to a device for harmlessly treating domestic waste. Background Art

[0002] Domestic waste harmless treatment equipment is a professional equipment used to treat urban domestic waste to achieve harmlessness, reduction and resource utilization. It covers various types such as waste incinerators, garbage shredders, landfill compactors, garbage composting and fermentation equipment, garbage pyrolysis and gasification equipment, sewage treatment equipment, etc. Through different technical means such as incineration, shredding, landfilling, composting, pyrolysis and gasification, it can effectively treat domestic waste, reduce pollution to the environment, and at the same time realize the recycling of some resources, playing an important role in improving urban environmental quality and promoting sustainable development.

[0003] In order to facilitate the subsequent harmless treatment of garbage incineration, garbage landfill, garbage composting fermentation and garbage pyrolysis and gasification, it is necessary to use a garbage shredder to shred the garbage. However, the existing garbage shredders generally use fixed cutters when shredding garbage (including dry garbage and wet garbage). This is fine for shredding dry garbage, but when shredding wet garbage, the fixed cutters cannot increase the cutting points to quickly shred the easily entangled wet garbage, resulting in increased equipment load and energy consumption, which can easily lead to accumulation and blockage of wet garbage. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the prior art, the present invention provides a domestic waste harmless treatment device, which can effectively solve the problem of inconsistent humidity of domestic waste in the prior art and inability to increase cutting points according to dry waste and wet waste.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] The present invention provides a domestic waste harmless treatment device, comprising:

[0007] base;

[0008] A power mechanism, the power mechanism comprising a box body fixedly connected to the upper end surface of the base;

[0009] A crushing mechanism, the crushing mechanism comprising a fixed block clamped to a side of the box away from the protective cover, at least two shredding assemblies arranged in parallel on a side of the fixed block close to the box, and a power mechanism driving the two shredding assemblies to rotate synchronously, a dispersion assembly provided on the inner wall of the box, and the dispersion assembly corresponding to the middle of the two shredding assemblies, a gas conduction assembly provided inside the shredding assembly, a linear array of the shredding assemblies alternately provided with multiple groups of cutter assemblies and multiple groups of suction and exhaust assemblies, and a suction and exhaust guide assembly interconnected with the gas conduction assembly provided on the side of the fixed block away from the shredding assembly;

[0010] A pneumatic mechanism comprising a protective box fixedly connected to the upper end surface of the base, wherein the interior of the protective box is divided into a release area and an air pressure area from top to bottom, wherein a fan and a compression box are provided in the release area, and wherein two air bags and a hollow block are fixedly connected in the air pressure area, and the hollow block is located between the two air bags;

[0011] An inflator is in communication with the gas conducting assembly.

[0012] Preferably, a motor is installed at the bottom of the base, and a controller is provided on the side of the base;

[0013] The inner bottom of the box is fixedly connected to a funnel, and the bottom of the box is fixedly connected to a discharge port that passes through the base. The inner wall of the box is fixedly connected to a humidity detector, and the humidity detector is electrically connected to the controller. The side of the box is fixedly connected to a protective cover, and the side of the box located inside the protective cover is rotatably connected to a power wheel, a transmission wheel and a side-by-side single-groove shaft and double-groove shaft from top to bottom, and the power wheel is in frictional contact with the transmission wheel. One of the notches of the double-groove shaft is connected to the notch of the single-groove shaft through a first belt, and the first belt is in frictional contact with the transmission wheel. The other notch of the double-groove shaft is connected to the output end of the motor through a second belt. The box is rotatably connected to the inner walls corresponding to the single-groove shaft and the double-groove shaft by two female buckle disks, and the axes of the single-groove shaft and the double-groove shaft pass through the box and are fixedly connected to the female buckle disks at corresponding positions.

[0014] Preferably, the dispersion component corresponds to the position of the power wheel, and the dispersion component includes a rotating shaft rotatably connected to the inner wall of the box, the rotating shaft is fixedly connected to the axis of the power wheel, and a plurality of tapered blocks are symmetrically provided at both ends of the shaft body;

[0015] The two shredding assemblies correspond to the positions of the single-slot shaft and the double-slot shaft respectively. The shredding assembly includes a hollow shaft rotatably connected to the side of the fixed block facing the box body. A plurality of shredding knives are fixedly connected to the outer peripheral surface of the hollow shaft in a linear array. The end of the hollow shaft away from the fixed block is fixedly connected to a sub-buckle, and the sub-buckle is clamped with the mother buckle disk.

[0016] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0017] 1. The shredder mechanism utilizes a disperser, shredder, and cutter assembly to disperse and shred aggregated waste. The disperser disperses waste before shredding, preventing large aggregates from concentrating in a single location within the shredder assembly. The shredder shreds dry waste and, in conjunction with the cutter assembly, shreds wet waste. The cutter assembly can be raised and lowered to varying degrees depending on the wetness of the wet waste. The disperser disperses waste before shredding, effectively preventing large aggregates from concentrating in a single location within the shredder assembly, ensuring a uniform and stable shredding process. The shredder efficiently shreds dry waste and, in conjunction with the cutter assembly, shreds wet waste, achieving a clear division of labor and strong adaptability. The cutter assembly can also be raised and lowered to varying degrees depending on the wetness of the wet waste, precisely matching shredding requirements. This improves shredding efficiency for waste of varying wetness, enhances waste treatment efficiency, and ensures the efficient and stable operation of the harmless waste treatment equipment.

[0018] 2. Through the gas conduction component, suction and exhaust component, suction and exhaust component and inflator in the crushing mechanism, it is possible to use gas to control the lifting and lowering of the cutter component, absorb liquid and spray intermittent airflow on the garbage. The gas conduction component is used to transmit different airflows in the air pressure mechanism and the inflator to the corresponding suction and exhaust component and cutter component respectively, so that the inflator controls the lifting height of the cutter component through the input gas volume, and the air pressure mechanism changes the air pressure intensity of the input intermittent airflow according to the humidity, controls the strength of the air column discharged by the suction and exhaust component, and can absorb excess moisture in the garbage when the humidity of the garbage is too high. The air pressure mechanism dynamically adjusts the air pressure intensity of the intermittent airflow according to the humidity of the garbage, and controls the strength of the air column discharged by the suction and exhaust component. When processing dry garbage, the sprayed intermittent airflow can disperse the garbage evenly, avoid garbage agglomeration, and allow the shredding component to fully act on every piece of garbage, thereby improving the shredding efficiency; when the humidity of the garbage is too high, the suction and exhaust component absorbs excess moisture in time, reduces the viscosity of the garbage, reduces the entanglement of the shredding blade, and ensures a smooth shredding process.

[0019] 3. Through the fan, electric slider, compression box, hollow block, air bag and hydraulic rod in the pneumatic mechanism, it is possible to deliver compressed air of corresponding strength to the suction and exhaust component according to the humidity of the garbage. The fan is used to absorb external air, the electric slider is used to change the space size of the compression box, the hollow block is used to receive the air sucked by the fan and further transfer it to the air bag, and the hydraulic rod can apply different pressures to the air bag according to the humidity of the garbage, thereby achieving different degrees of compression of the gas in the air bag. By delivering compressed air of corresponding strength to the suction and exhaust component according to the humidity of the garbage, when processing high-humidity garbage, a strong airflow can effectively blow away the garbage, facilitating subsequent shredding and moisture absorption; when processing low-humidity garbage, a moderate airflow assists in shredding to avoid excessive dust. This not only improves the pertinence and effectiveness of garbage treatment, but also ensures the stable and efficient operation of the entire pneumatic mechanism and related processing processes, thereby improving the quality and efficiency of garbage shredding.

[0063] The operating principle of this embodiment is as follows:

[0064] The first step: turn on the device through the controller (the device in this solution refers to the harmless treatment equipment for domestic waste). First, the motor 11 at the bottom of the base 1 starts to work. The output end of the motor 11 is connected to a notch of the double-grooved shaft 27 through the second belt, driving the double-grooved shaft 27 to rotate. The other notch of the double-grooved shaft 27 is connected to the notch of the single-grooved shaft 26 through the first belt. At the same time, the first belt is in friction contact with the transfer wheel 25, so that the single-grooved shaft 26 and the transfer wheel 25 rotate synchronously with the double-grooved shaft 27. The transfer wheel 25 is in friction contact with the power wheel 24, driving the power wheel 24 to rotate, so that the power mechanism 2 provides power for the operation of the entire device;

[0065] Then pour the domestic garbage into the box 21. At this time, the humidity detector 28 (the humidity detector 28 is a capacitive humidity sensor) on the inner wall of the box 21 starts to detect the humidity in the domestic garbage. The humidity detector 28 converts the detected humidity information into an electrical signal and transmits it to the controller. The controller has preset processing programs corresponding to different humidity ranges. After receiving the humidity signal, the controller controls the working power and operating status of the air pressure mechanism 4 and the inflator 5 according to the preset program.

[0066] The controller is provided with a judgment range of the dryness and humidity of the domestic garbage. The controller can compare the actual humidity of the current garbage detected by the humidity detector 28 with the judgment range of the garbage dryness and humidity to determine whether the garbage is dry garbage or wet garbage:

[0067] Implementation standard A: If the moisture content (water weight ratio) of garbage is less than 30%, it is considered dry garbage;

[0068] Implementation standard B: If the moisture content of garbage is between 30% and 70%, it is considered wet garbage;

[0069] Implementation standard C: If the moisture content of the garbage is higher than 70%, it is judged to be too much moisture.

[0070] Since the power of the dispersion assembly 32 comes from the power wheel 24, when the motor 11 drives the power wheel 24 to rotate, the rotating shaft 321 connected to the axis of the power wheel 24 rotates synchronously, and the conical block 322 in the rotating shaft 321 also rotates synchronously.

[0071] Since the surface linear velocity of the conical block 322 is relatively high when it rotates, the centrifugal force and mechanical collision principle are used to disperse the garbage. The high-speed rotating conical block 322 forms a dynamic dispersion area. When garbage approaches, the high-speed rotation of the conical block 322 generates a relatively high linear velocity, exerting a mechanical impact force on the garbage, breaking up the agglomerated garbage. At the same time, the centrifugal force causes the dispersed garbage to spread outward and be evenly distributed in the shredder assembly 33, thus preventing a large amount of garbage from gathering in a certain position of the shredder assembly 33.

[0072] It should be noted that the dispersion component 32 has different effects on the dispersion of dry garbage and wet garbage:

[0073] When dispersing dry garbage: Since dry garbage is relatively hard, it agglomerates due to squeezing and entanglement. When the rotating conical block 322 collides with the dry garbage, the impact force generated by the dry garbage and the conical block 322 can effectively break up these agglomerated structures. For example, some clumped dry garbage such as paper and plastic fragments are broken up by the impact of the conical block 322. At the same time, the centrifugal force causes the broken dry garbage to fly around and be evenly distributed in front of the shredder assembly 33, ensuring that the dry garbage can fully contact the shredder blades 332, thereby improving the shredding efficiency and avoiding the situation where insufficient shredding is caused by local concentration.

[0074] When dispersing wet garbage: wet garbage usually has a certain viscosity and is easy to stick together into large lumps, which brings difficulties to subsequent processing. When the dispersing component 32 is working, the rotating conical block 322 will cut into the wet garbage clumps. Because of the conical shape of the conical block 322, the linear speed and movement direction of different positions during rotation are different, which will generate shear force and extrusion force. At the same time, since the high-speed rotation of the conical block 322 has a large kinetic energy, it will be converted into impact force when it contacts the wet garbage clumps, causing stress inside the clumps. When the stress exceeds the viscosity inside the clumps, The clumps begin to break due to the force, and the shear force generated by the inclined surface of the conical block 322 can cut off the sticky connection inside the wet garbage, and the extrusion force squeezes the clumps to the surroundings. Multiple conical blocks 322 act from different angles and continuously rotate to continuously apply force to the wet garbage. Therefore, even wet garbage such as food residues with high viscosity can be gradually separated and maintained in a relatively dispersed state before entering the shredding component 33, making it easier for the cutter component 35 and the shredding knife 332 to work together to shred the wet garbage, reducing the phenomenon of wet garbage entangled with the cutter, and improving the overall processing efficiency.

[0075] When the motor 11 drives the single-groove shaft 26 and the double-groove shaft 27 to rotate, the hollow shaft 331 of the shredder assembly 33 rotates synchronously, thereby shredding the garbage through the shredder blade 332 (the shredder blade 332 is mainly suitable for shredding dry garbage);

[0076] When the garbage humidity signal transmitted to the controller by the humidity detector 28 meets the execution standard A (dry garbage):

[0077] Driven by the power mechanism 2, the hollow shaft 331 of the shredder assembly 33 rotates synchronously, causing the shredder blades 332 to rotate at high speed, thereby causing the shredder blades 332 to shred the dry garbage (when shredding according to Standard A is executed, the shredder assembly 35 does not operate). At this time, the two-position three-way valve 376 switches to communicate with the second conduit 347, thereby releasing the intermittent compressed gas generated by the air pressure mechanism 4 through the suction and discharge assembly 36;

[0078] As the controller starts the air pressure mechanism 4 (the working process of the air pressure mechanism 4 when it is started will be described below), the intermittent compressed gas generated by the air pressure mechanism 4 is transmitted to the diverter ring 343 through the gas conduction component 34, and the diverter rings 343 are interconnected through the intercommunication pipe 344 to make the gas evenly distributed. The suction and discharge component 36 corresponding to the position of the diverter ring 343 has its air pipe 361 bottom end passing through the hollow shaft 331 and connected to the diverter ring 343, thereby receiving the intermittent compressed gas from the diverter ring 343. When gas enters the air pipe 361, , the internal air pressure increases, and the sealing pieces 362 slidingly connected at both ends of the air pipe 361 keep the air pipe 361 sealed under the action of the telescopic rod 364 and the spring 365. As the gas continues to enter, when the air pressure reaches a certain level, the sealing piece 362 is pushed to slide to one end, the air pipe 361 opens, and the gas is quickly discharged to form intermittent airflow with a certain pressure. These intermittent airflows are sprayed onto the dry garbage, making the dry garbage evenly dispersed and avoiding garbage agglomeration, so that the shredder 332 of the shredder assembly 33 can fully act on every piece of dry garbage.

[0079] It should be noted that:

[0080] When the cutter assembly 35 needs to be used, the controller does not energize the electromagnet 356 (the electromagnet 356 does not generate magnetism at this time, releasing the cutter assembly 35);

[0081] Based on the current garbage humidity transmitted by the humidity detector 28, the controller controls the inflator 5 (the inflator 5 is equivalent to the air pump in the prior art) to deliver gas to the connecting pipe 345. The amount of gas is determined by the controller based on the current garbage humidity feedback from the humidity detector 28. When the gas in the connecting pipe 345 increases, the hollow telescopic tube 351 extends due to the increase in internal air pressure, pushing the hollow slider 352 to slide upward on the outer circumference of the hollow shaft 331. The elastic blocks 353 fixed in the linear array on both sides of the hollow slider 352 rise accordingly, driving the cutter 354 to rise.

[0082] When not in use, the controller energizes the electromagnet 356 (at this time, the electromagnet 356 generates magnetism to lock the cutter assembly 35 and the hollow shaft 331).

[0083] When the garbage humidity signal transmitted to the controller by the humidity detector 28 meets the execution standard B (wet garbage):

[0084] The controller instructs the inflator 5 to increase the gas output so that the cutter 354 rises to a height that meets the value within the range of standard B (the specific rise height of the cutter 354 corresponding to each value can be customized by the staff in the controller according to the actual situation. For example: when the garbage humidity is between 30% and 50%, the rise height of the cutter 354 can be set to 2-3 cm. This height can assist the shredder 332 in shredding effectively and avoid overloading the equipment; when the humidity is between 50% and 70%, the rise height of the cutter 354 can be set to 4-5 cm. This height can reduce the entanglement of the garbage cutter and improve the shredding efficiency; and when the garbage humidity reaches 70% to 90%, the cutter 354 is completely raised. When the cutter 354 rises to a suitable height, it cooperates with the high-speed rotating shredder 332. Driven by the hollow shaft 331, the shredder 332 rotates at high speed to initially crush the wet garbage. The cutting edge of the cutter 354 and the relative motion with the shredder 332 further cut and shred the wet garbage. Wet garbage is usually sticky and easily entangled on the cutting tool. However, the cooperation between the cutter 354 and the shredder 332 can effectively reduce the entanglement phenomenon because the cutter 354 can cut larger pieces of wet garbage into small pieces, and the shredder 332 can further shred these small pieces into finer particles, thereby improving the shredding effect of the wet garbage and making it more suitable for subsequent processing requirements.

[0085] When the garbage humidity signal transmitted to the controller by the humidity detector 28 meets the execution standard C (too much moisture): the two-position three-way valve 376 will switch to connect with the drain pipe 375, and the drain pipe 375 will be connected to the sewage treatment equipment (the sewage treatment equipment contains a water pump), and the water pump will start to generate suction. At this time, the air pressure in the air pipe 361 is much lower than the external air pressure, forming a large air pressure difference. Under the action of the strong air pressure difference, the sealing piece 362 quickly slides toward the end where the suction is generated, and the air pipe 361 is fully opened. A large amount of water in the wet garbage is quickly sucked into the air pipe 361 under the action of suction. The telescopic rod 364 and the spring 365 on both sides of the fixed seat 363 will greatly expand and contract with the rapid movement of the sealing piece 362, playing a role of buffering and The function of the stable sealing plate 362 is to ensure that the suction and discharge component 36 can absorb moisture continuously and stably. The input end of the connecting valve 371 of the suction and discharge guide component 37 is connected to the first collecting pipe 341, and receives the gas containing a large amount of moisture from the first collecting pipe 341. The diversion pipe 372 connected to the output end of the connecting valve 371 transports these gases and moisture to the three-way valve 373. The three-way valve 373 collects the gas and moisture and inputs them into the second collecting pipe 374. Finally, the moisture is transported to the sewage treatment equipment for treatment through the two-position three-way valve 376 and the drain pipe 375. Until the garbage humidity signal detected by the humidity detector 28 reaches the range of the execution standard B, the sewage treatment equipment stops working and executes the shredding process when executing standard B.

[0086] Step 2: When the air pressure mechanism 4 is activated:

[0087] The fan 42 on the side of the protective box 41 is started first, thereby sucking in the outside air. The sucked air enters the three-way pipe 421 through the air outlet end of the fan 42. The two input ends of the three-way pipe 421 are fixedly connected with the hollow block 45 through a one-way valve, and the air enters the hollow block 45. The one-way valve can prevent the gas from flowing back, ensuring that the air can only flow to the hollow block 45 in one direction. The air entering the hollow block 45 will further enter the air bag 46, generating a pressure relief solenoid valve in a closed state, preventing the gas from flowing back into the compression box 44, ensuring that the air smoothly enters the compression box 44 and the air bag 46. At this time, the gas is in a preliminary collection and temporary storage state. The airbag 46 is in a state of being prepared for subsequent compression and use. Then, the hydraulic rods 47 on both sides of the airbag 46 operate under the control of the controller. The controller issues instructions to control the extension and contraction of the hydraulic rods 47 based on the garbage humidity information detected by the humidity detector 28. When the garbage humidity is detected to be high, the controller instructs the hydraulic rods 47 to extend, applying greater pressure to the airbag 46. According to Pascal's law, the gas in the airbag 46 is compressed under the action of pressure, the distance between gas molecules decreases, and the air pressure increases. When the garbage humidity is low, the hydraulic rods 47 moderately extend and contract, applying less pressure to the airbag 46, so that the gas in the airbag 46 remains moderately compressed.

[0088] Among them, when the air bag 46 completes the compression of the gas, the pressure relief solenoid valve opens, allowing the gas to enter the compression box 44. After the gas enters the compression box 44, since the electric slider 43 is electrically connected to the controller, the controller controls the movement of the electric slider 43 according to the garbage humidity information detected by the humidity detector 28. When the garbage humidity is high and a stronger airflow is required for auxiliary processing, the controller instructs the electric slider 43 to slide along the slide rail 411 toward the compression box 44, the space of the compression box 44 becomes smaller, and the pressure of the gas in the compression box 44 further increases; on the contrary, when the garbage humidity is low and a weaker airflow is required, the electric slider 43 moves away from the compression box 44. , the space of the compression box 44 becomes larger, and the gas pressure decreases. The output end of the compression box 44 is connected to the second collecting pipe 374. The compressed gas adjusted by the electric slider 43 enters the suction and discharge guide assembly 37 through the second collecting pipe 374 under the action of pressure. In the suction and discharge guide assembly 37, the gas passes through the connecting valve 371, the diverter pipe 372, and the three-way valve 373 in sequence, and finally enters the other end of the second collecting pipe 374. Then, the gas passes through the two-position three-way valve 376 (at this time, the two-position three-way valve 376 is not connected to the drain pipe 375) and enters the air pipe 361 connected to the suction and discharge assembly 36, thereby realizing intermittent gas delivery to the suction and discharge assembly 36.

[0089] Step 3: As the shredding process continues, garbage continues to accumulate in the box body 21. Under the action of gravity, the shredded garbage falls to the funnel 22 fixedly connected at the bottom. The inclined inner wall of the funnel 22 guides the garbage to gather, and finally the garbage enters the discharge port 29 fixedly connected to the bottom of the box body 21 and passing through the base 1. Under the action of gravity and the positive pressure that may exist inside the equipment, the garbage is discharged from the equipment through the discharge port 29 and enters the subsequent processing steps.
