Description

Technical Field

[0001] The present invention relates to the technical field of kitchen waste treatment, and in particular to a kitchen waste treatment device. Background Art

[0002] Fertilization of kitchen waste is a process of converting organic waste such as fruit peels, vegetable leaves, and coffee grounds into fertilizer rich in nitrogen, phosphorus, potassium, and organic matter through microbial decomposition. This not only reduces the amount of landfill, but also provides natural nutrients for plants, thus achieving resource recycling.

[0003] When using food waste to make fertilizer, it is necessary to spray bacteria into the waste to create favorable fermentation conditions. A search revealed that Chinese Patent Publication No. CN114409442A discloses a food waste recycling and fertilizer production device for fermenting food waste and other domestic waste in an aerobic environment. The food waste recycling and fertilizer production device includes a fermentation chamber, a crushing mechanism, and a stirring mechanism. The fermentation chamber includes a housing and a filter screen disposed within the housing and defining a fermentation chamber. The stirring mechanism includes a stirring blade and a drive assembly. The stirring blade is located in the fermentation chamber and rotates about a vertical axis driven by the drive assembly. Rotation of the stirring blade propels the food waste upward and toward the filter screen, assisting in the discharge of moisture from the food waste through the filter screen. It also causes the food waste to tumble and flow within the fermentation chamber, accelerating the evaporation of moisture within the food waste and ensuring sufficient contact between the food waste and air, thereby improving the fertilizer production effect. However, the above solution still has the following deficiencies in actual use: When adding bacteria to food waste in the above-mentioned scheme, the bacteria are usually sprayed directly into the waste and then mixed with the waste by stirring. The surface bacteria, due to direct contact with oxygen and suitable temperature and humidity conditions, may rapidly multiply and consume easily decomposable substances on the surface. However, the waste inside may be in an environment with low bacteria concentration for a long time due to delayed bacteria penetration or insufficient stirring, resulting in reduced decomposition efficiency. At the same time, excessive activity of surface bacteria may cause local high temperatures, accelerate nutrient volatilization or produce odors, while the waste that has not been fully decomposed inside may breed anaerobic bacteria and produce harmful gases such as hydrogen sulfide, further affecting the quality of the compost.

[0004] Therefore, it is necessary to design a kitchen waste treatment device to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a kitchen waste treatment device.

The discharge assembly includes a discharge hopper, which is movably arranged inside the frame, and a push rod is fixed to the side of the discharge hopper. The frame is provided with a spraying assembly inside for spraying the bacterial agent; The frame is provided with two pushing components, and the two pushing components are used to provide bacterial agent into the installation tube.

[0007] As a preferred technical solution of the present invention, the discharge assembly also includes a connecting pipe and a driving module, one end of the connecting pipe is connected to the discharge hopper, and the other end is connected to the discharge port, and the driving module is installed on the frame to drive the discharge hopper.

[0008] As a preferred technical solution of the present invention, when the discharge hopper moves to a position facing the baffle, the bottom end of the discharge hopper fits into the baffle.

[0009] As a preferred technical solution of the present invention, the injection assembly includes a mounting tube, which is fixed inside the frame and located below the two baffles. A number of fan-shaped nozzles are installed on the mounting tube, and the nozzle of each fan-shaped nozzle is set downward. A number of fan-shaped nozzles are distributed in a linear array. Both ends of the mounting tube are fixed with a fixing ring, and both ends of the mounting tube are slidably provided with a sliding ring. A fixing rod is fixed on each of the two sliding rings, and the adjacent fixing rings are connected to the corresponding sliding rings by a connecting spring. A sliding plate is arranged below the mounting tube, and a number of openings are opened on the sliding plate. Rod bodies are fixed on both ends of the sliding plate, and the ends of the two rod bodies away from the sliding plate are respectively connected to the two sliding rings.

[0010] As a preferred technical solution of the present invention, the nozzle portion of each fan-shaped nozzle is in contact with the sliding plate.

[0011] As a preferred technical solution of the present invention, in an initial state, under the elastic force of the two connecting springs, the plurality of openings and the plurality of fan-shaped nozzles are in a one-to-one misaligned state.

[0012] As a preferred technical solution of the present invention, the pushing assembly includes a sealing cylinder, which is fixed to one side of the frame, and the internal sealing sliding connection of the sealing cylinder is connected to a sliding plug, and a push rod is fixed to the side of the sliding plug, and the push rod extends to the outside of the sealing cylinder at one end away from the sliding plug. The sliding plug and the sealing cylinder are connected by a return spring, and two assembly tubes are connected to the sealing cylinder, and both of the assembly tubes are equipped with a one-way valve, one end of the assembly tube away from the sealing cylinder is connected to the bacterial agent storage tank, and the other end of the assembly tube away from the sealing cylinder is connected to the installation tube.

[0013] As a preferred technical solution of the present invention, the two one-way valves have opposite flow limiting directions, wherein one of the one-way valves limits the bacterial agent to only be able to enter the sealed cylinder, and the other one-way valve limits the bacterial agent to only be able to flow out of the sealed cylinder.

[0016] The present invention has the following beneficial effects: 1. This device realizes that every time a layer of waste is discharged from the discharge hopper, the fan-shaped nozzle evenly sprays the bacterial strain onto the surface of the waste layer, so that the bacterial strain and the waste are superimposed layer by layer. This layered addition method ensures that the bacterial strain can be evenly distributed in the waste, providing a good growth and reproduction environment for the bacterial strain, which is conducive to the full play of the bacterial strain and accelerates the fermentation and decomposition process of the waste, thereby improving the quality and yield of the fermentation product; 2. The setting of the push component can automatically pump the bacterial agent, using the discharge hopper as the power source, without the need to set up additional power sources such as pumps, which reduces the energy consumption of the entire system, conforms to the concept of energy conservation and environmental protection, and reduces operating costs; 3. The bacterial agent accumulates pressure in the installation tube and is released instantly only when the opening of the sliding plate is aligned with the nozzle, forming an atomized spray effect. This design not only saves the amount of bacterial agent used, but also ensures a wide spray coverage and strong penetration, and is especially suitable for the uniform distribution of high-viscosity bacterial liquid.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-9 A food waste treatment device includes a mixing machine 1. A frame 2 is provided above the mixing machine 1 and is fixedly connected to the frame 2. The frame 2 has open ends at both ends. Two opposing baffles 21 are fixed inside the frame 2. A bacterial agent storage tank 22 is fixed to the side of the frame 2. The bacterial agent storage tank 22 is used to store bacterial agents for fermentation. A material tank 3 is provided above the frame 2. The material tank 3 is used to store food waste. The material tank 3 is connected to the frame 2 via a connecting plate 31. A discharge port is provided on the bottom of the material tank 3 for discharging waste. The frame 2 is provided with a discharge assembly for discharging kitchen waste. The discharge assembly includes a discharge hopper 41, a connecting pipe 42 and a driving module 43. The discharge hopper 41 is arranged inside the frame 2. One end of the connecting pipe 42 is connected to the discharge hopper 41, and the other end is connected to the discharge port. The connecting pipe 42 adopts a hose so that the discharge hopper 41 can move. The driving module 43 is installed on the frame 2 and is used to drive the discharge hopper 41. The driving module 43 may include a motor, a reciprocating screw and a guide rod. The reciprocating screw is rotatably installed on the frame 2. The guide rod The rod is fixed on the frame 2, the motor is installed on the side of the frame 2, and the output shaft of the motor is connected to one end of the reciprocating screw rod, the reciprocating screw rod is threaded with a movable seat, the guide rod is slidably sleeved with a sliding seat, and the movable seat and the sliding seat are both fixed on the discharge hopper 41. When the motor is running, it can drive the reciprocating screw rod to rotate. Under the limiting action of the guide rod and the guide seat, the reciprocating screw rod can drive the discharge hopper 41 to reciprocate inside the frame 2 when it rotates. Furthermore, the driving module 43 can also use other devices with linear drive functions, which will not be described in detail here. When discharging, the driving module 43 operates and drives the discharge hopper 41 to move back and forth inside the frame 2. When the discharge hopper 41 moves to both sides of the frame 2, the bottom of the discharge hopper 41 just fits with the baffles 21 at the corresponding position. At this time, the baffles 21 can block the discharge hopper 41, and the waste cannot be discharged through the discharge hopper 41 temporarily. When the discharge hopper 41 moves in the area between the two baffles 21, the waste can fall downward through the discharge hopper 41 and fall into the mixing mixer 1. Furthermore, whenever the discharge hopper 41 moves to a position facing the baffle 21, the driving module 43 is suspended and the discharge action of the waste stops accordingly, so as to achieve intermittent discharge of the waste. It is worth noting that the connecting pipe 42 adopts a flexible pipe. When the discharge hopper 41 moves, the connecting pipe 42 can be deformed accordingly. This design can prevent the connecting pipe 42 from hindering the movement of the discharge hopper 41. The frame 2 is provided with a spray assembly for spraying the bacterial agent. The spray assembly includes a mounting tube 51, which is fixed inside the frame 2 and located below the two baffles 21. A plurality of fan-shaped nozzles 52 are mounted on the mounting tube 51. The nozzles of each fan-shaped nozzle 52 are all facing downwards. The plurality of fan-shaped nozzles 52 are distributed in a linear array. Both ends of the mounting tube 51 are fixedly sleeved with a fixing ring 53. Both ends of the mounting tube 51 are slidably sleeved with a sliding ring 56. The adjacent fixing rings 53 and the corresponding sliding rings 56 are slidably sleeved. The rings 56 are connected by connecting springs 57. A sliding plate 54 is arranged below the mounting tube 51. The sliding plate 54 is provided with a plurality of openings 55. Rods 59 are fixed at both ends of the sliding plate 54. The ends of the two rods 59 away from the sliding plate 54 are respectively connected to the two sliding rings 56. The nozzle part of each fan-shaped nozzle 52 is fitted with the sliding plate 54. In the initial state, under the elastic force of the two connecting springs 57, the plurality of openings 55 and the plurality of fan-shaped nozzles 52 are in a one-to-one misalignment state, forming a Figure 7 In the state shown, the sliding plate 54 blocks the plurality of fan-shaped nozzles 52, and the bacterial agent cannot be sprayed out through the plurality of fan-shaped nozzles 52; The frame 2 is provided with two pushing assemblies, which are used to provide the bacterial agent into the installation tube 51. Each pushing assembly includes a sealing cylinder 61, which is fixed to one side of the frame 2. The interior of the sealing cylinder 61 is sealingly and slidably connected to a sliding plug 62. A push rod 66 is fixed to the side of the sliding plug 62. The end of the push rod 66 away from the sliding plug 62 extends to the outside of the sealing cylinder 61. The sliding plug 62 and the sealing cylinder 61 are connected by a return spring 63. Two assembly pipes 64 are connected to the sealing cylinder 61. Both assembly pipes 64 are equipped with a one-way valve 65. The flow limiting directions of the two one-way valves 65 are opposite. One of the one-way valves 65 restricts the bacterial agent from entering the sealing cylinder 61, and the other one-way valve 65 restricts the bacterial agent from flowing out of the sealing cylinder 61. One end of one assembly pipe 64 away from the sealing cylinder 61 is connected to the bacterial agent storage tank 22, and the other end of the other assembly pipe 64 away from the sealing cylinder 61 is connected to the installation tube 51. In the initial state, under the elastic force of the return spring 63, the slide plug 62 is located at the cylinder mouth position of the sealing cylinder 61. When the discharge hopper 41 moves to the side of the frame 2, the discharge hopper 41 will squeeze the push rod 66, so that the push rod 66 drives the slide plug 62 to move. When the slide plug 62 moves, the bacterial agent in the sealing cylinder 61 can be pushed into the installation tube 51 through the corresponding assembly tube 64. Before the discharge hopper 41 moves to the position facing the baffle 21, the bacterial agent will temporarily accumulate in the installation tube 51, which keeps a certain pressure inside the installation tube 51. When the discharge hopper 41 moves to a position facing the baffle 21, the sliding plate 54 moves so that the openings 55 face the fan-shaped nozzles 52 respectively. At this time, the bacterial agent in the installation tube 51 can be sprayed out through the fan-shaped nozzles 52. Conversely, when the discharge hopper 41 moves away from the sealing cylinder 61, the sliding plug 62 is reset under the action of the reset spring 63. When the sliding plug 62 is reset, the sliding plug 62 can extract the bacterial agent in the bacterial agent storage tank 22 through the corresponding assembly tube 64, realizing automatic replenishment of the bacterial agent and preparing for the next bacterial agent push. A fixing rod 58 is fixed on each of the two sliding rings 56, and a push rod 411 is fixed on the side of the discharge hopper 41, and the push rod 411 is located between the two fixing rods 58. When the discharge hopper 41 moves to a position facing the baffle 21, the push rod 411 on the discharge hopper 41 just pushes the fixing rod 58 below the baffle 21, so that the fixing rod 58 drives the corresponding sliding ring 56 to move. When the sliding ring 56 moves, it can drive the sliding plate 54 to move through the rod body 59, and the plurality of openings 55 on the sliding plate 54 move accordingly, until the plurality of openings 55 are respectively moved to a position facing the plurality of fan-shaped nozzles 52, forming a Figure 9 In the state shown, the sliding plate 54 no longer blocks the plurality of fan-shaped nozzles 52 , and the bacterial agent in the mounting tube 51 can be sprayed out through the plurality of fan-shaped nozzles 52 ; Based on the above process, when the discharge hopper 41 moves in the area between the two baffles 21, the discharge hopper 41 discharges the waste. At this time, the push rod 411 moves in the area between the two fixed rods 58, and the fan-shaped nozzles 52 cannot perform the spraying action. When the discharge hopper 41 moves to a position facing the baffle 21, the waste discharge action stops. At the same time, the push rod 411 pushes the fixed rod 58 under the baffle 21, causing the sliding plate 54 to move. At this time, the bacterial agent can be sprayed out through the fan-shaped nozzles 52 and evenly sprayed onto the surface of the waste. The effect achieved by this design is: every time the discharge hopper 41 discharges a layer of waste, the fan-shaped nozzles 52 will spray the bacterial strain toward the surface of the waste layer, so that the waste and the bacterial strain are superimposed layer by layer. The superposition of the waste and the bacterial strain provides a good growth and reproduction environment for the bacterial strain, which is conducive to the full play of the bacterial strain, accelerates the fermentation decomposition process of the waste, and improves the quality and yield of the fermentation product.

[0021] The specific working principle of the present invention is as follows: When the kitchen waste treatment device is in operation, the kitchen waste in the material tank 3 first enters the discharge hopper 41 through the discharge port through the connecting pipe 42. The motor in the drive module 43 is turned on, driving the reciprocating screw to rotate. Under the limiting action of the guide rod and the sliding seat, the reciprocating screw drives the movable seat to move, thereby driving the discharge hopper 41 to reciprocate inside the frame 2. When the discharge hopper 41 moves in the area between the two baffles 21, the waste can fall downward through the discharge hopper 41 and fall into the structure below, realizing the waste discharge action. When the discharge hopper 41 moves to both sides of the frame 2, its bottom is in contact with the corresponding baffle 21, which blocks the discharge hopper 41, temporarily preventing the waste from being discharged. Whenever the discharge hopper 41 moves to a position facing the baffle 21, the drive module 43 stops operating, thereby realizing intermittent waste discharge. At the same time, the connecting pipe 42 is a flexible pipe that can deform as the discharge hopper 41 moves to avoid obstructing its movement. During the discharge process, when the discharge hopper 41 moves to the side of the frame 2, it squeezes the push rod 66 on the sealing cylinder 61 in the pushing assembly, and the push rod 66 drives the sliding plug 62 to move in the sealing cylinder 61. When the sliding plug 62 moves, the bacterial agent in the sealing cylinder 61 is pushed into the installation tube 51 through the corresponding assembly tube 64. Before the discharge hopper 41 moves to the position facing the baffle 21, the bacterial agent is temporarily accumulated in the installation tube 51, so that a certain pressure is maintained inside the installation tube 51; when the discharge hopper 41 moves away from the sealing cylinder 61, the sliding plug 62 is reset under the action of the reset spring 63. When resetting, the bacterial agent in the bacterial agent storage tank 22 is extracted through the corresponding assembly tube 64 to achieve automatic replenishment; When the discharge hopper 41 moves to a position facing the baffle 21, on the one hand, the waste discharge action stops, and on the other hand, the push rod 411 on the side of the discharge hopper 41 just pushes the fixed rod 58 under the baffle 21, and the fixed rod 58 drives the corresponding sliding ring 56 to move, and the sliding ring 56 drives the sliding plate 54 to move through the rod body 59. The plurality of openings 55 on the sliding plate 54 move to a position facing the plurality of fan-shaped nozzles 52. At this time, the sliding plate 54 no longer blocks the fan-shaped nozzles 52, and the bacterial agent accumulated and maintained under pressure in the mounting tube 51 can be evenly sprayed onto the surface of the waste just discharged through the plurality of fan-shaped nozzles 52. This cycle continues, and each time the discharge hopper 41 discharges a layer of waste, the plurality of fan-shaped nozzles 52 will spray the bacterial strain toward the surface of the waste layer, so that the waste and the bacterial strain are superimposed layer by layer, providing a good growth and reproduction environment for the bacterial strain, accelerating the fermentation and decomposition of the waste, and improving the quality and yield of the fermentation product.
