The system includes a spray assembly and a braking assembly inside the housing. The braking assembly includes a time delay switch and a humidity sensor, both of which are installed on the outside of the housing. A PLC controller is installed on the inner wall of the housing. The spray assembly includes a first cylinder.
[0004] The shortcomings of existing spray deodorization systems:
[0005] Structural defects of the mixing tank: The mixing chamber is not separated from the drug storage tank, and there is a lack of liquid circulation mechanism, which can easily cause drug precipitation or concentration stratification.
[0006] Limited mobility: The equipment relies on vehicle power and cannot be moved independently to other work areas.
[0007] Limited nozzle coverage: The nozzles are only designed for specific areas of the vehicle (such as the garbage collection point), and cannot adapt to the complex terrain and large-area deodorization needs of food waste treatment sites.
[0008] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a mobile spray deodorization device for kitchen waste, making it more valuable for industrial use. Utility Model Content

Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0038] The first embodiment of this utility model:
[0039] like Figure 1 and Figure 3 As shown, a mobile spray deodorization device for kitchen waste in this embodiment mainly includes a liquid storage tank 1, a drain pipe 4, a manifold 5, a nozzle unit 6, a medicine storage tank 17, a medicine inlet pipe 18, and a mixing tank 21.
[0040] At least one handle 2 is installed on the liquid storage tank 1 for easy manual operation. Casters 3 are installed at the bottom of the liquid storage tank 1 for easy manual movement of the liquid storage tank 1. An external power mechanism is required, and the tank can be freely moved to the work area via the casters.
[0041] Inside the liquid storage tank 1, an upper tank 14 and a lower tank 16 are arranged sequentially from top to bottom, and the upper tank 14 and the lower tank 16 are separated by a partition 15. A medicine storage tank 17 is installed in the upper tank 14, and a mixing tank 21 is installed in the lower tank 16.
[0042] The connection structure between the drug storage tank 17, the mixing tank 21, and the external drain pipe 4 and manifold 5 is as follows:
[0043] A drug inlet pipe 18 is installed on the first side of the drug storage tank 17. The drug inlet pipe 18 can extend to the outside of the liquid storage tank 1 to replenish the drug solution inside the drug storage tank 17. A drug outlet pipe 19 is installed on the second side of the drug storage tank 17. The drug outlet pipe 19 is connected to the mixing tank 21 below under the action of the first pump 20 to transport the drug solution in the drug storage tank 17 to the mixing tank 21 below.
[0044] A water inlet pipe 22 is installed on the mixing tank 21. The water inlet pipe 22 can extend to the outside of the liquid storage tank 1 to replenish water into the mixing tank 21, and can be filtered by the filter 23.
[0045] The mixing tank 21 is connected to the bottom side of the drain pipe 4 via the outlet pipe 7 and the second pump 24, and the mixing tank 21 is connected to the middle side of the drain pipe 4 via the return pipe 8. The top side of the drain pipe 4 is connected to the manifold 5, and several nozzle units 6 are installed at the bottom of the manifold 5.
[0046] The second embodiment of this utility model:
[0047] like Figure 2 As shown, based on the first embodiment described above, at least one support mechanism is installed at the bottom of the liquid storage tank 1. The support mechanism includes a support frame 9, a screw 10, and a support leg 12. The support frame 9 is installed at the bottom of the liquid storage tank 1. A screw 10 that can be adjusted vertically is installed on the support frame 9. A rotating handle 11 for top limiting is installed on the top of the screw 10. A support leg 12 for bottom support is installed on the bottom of the screw 10. Several downward-facing contact protrusions 13 are installed on the bottom of the support leg 12. The contact area between the support leg 12 and the ground can be increased by the several contact protrusions 13.
[0048] When moving, the equipment can be quickly moved using casters 3; when working, the height of the support legs 12 can be adjusted by rotating the screw 10, so that the contact protrusions 13 are in close contact with the ground, thereby enhancing the stability of the equipment and adapting to uneven working environments.
[0049] The third embodiment of this utility model:
[0050] like Figure 4 As shown, the nozzle unit 6 in this embodiment includes a nozzle body 25. The top of the nozzle body 25 is installed at the bottom of the manifold 5 through a nozzle connector 26. A plurality of first nozzle holes 27 are installed on the side of the nozzle body 25, and a plurality of second nozzle holes 28 are installed at the bottom of the nozzle body 25.
[0051] The nozzle connector 26 can be designed with quick release and sealed with an O-ring, allowing for quick disassembly and cleaning of the nozzle.
[0052] The first spray hole 27 on the side and the second spray hole 28 at the bottom of the nozzle body 25 form a 360° three-dimensional spray range, which can simultaneously cover the surface of kitchen waste and the surrounding air, solving the problem of the single direction of the existing patented nozzles.
[0053] The fourth embodiment of this utility model:
[0054] In addition, the nozzle unit 6 in this embodiment includes a nozzle body 25, the top of which is mounted on the bottom of the manifold 5 via a nozzle connector 26, and the nozzle body 25 is an atomizing nozzle.
[0055] The nozzle body 25 adopts an atomization design with a mist particle diameter of ≤40μm, which can remain suspended in the air for a long time and efficiently decompose odor molecules through adsorption, neutralization and other processes.
[0056] A brief description of the working process of the above-described embodiments:
[0057] I. Equipment Moving and Positioning Stage
[0058] Mobile operation: The operator pushes the equipment by using the handles 2 (wrapped with non-slip rubber, grip coefficient ≥0.8) on both sides of the liquid storage tank 1. The bottom casters 3 (150mm in diameter, with bearing casters) can turn 360°. The moving speed can reach 0.5m / s on flat surfaces such as cement and asphalt, and can be easily transferred to the food waste collection point (such as next to the garbage can or the edge of the temporary storage area).
[0059] Support and Fixation: After reaching the target position, rotate the top handle of the screw 10 of the support mechanism clockwise (rotation torque 5-8 N·m). The trapezoidal thread (pitch 5 mm) drives the screw to descend vertically along the support frame 9 until the contact protrusion 13 (hemispherical rubber material, diameter 15 mm) at the bottom of the support leg 12 is in close contact with the ground. At this time, observe the levelness of the equipment with a level and adjust the four support mechanisms (distributed at the four corners of the box) to ensure the deviation is ≤0.5°. Finally, ensure that the movable caster 3 is completely off the ground (gap ≥10 mm) and the rotating handle 11 is in contact with the top surface of the support frame 9 (gap ≤0.5 mm) to prevent the screw from coming off.
[0060] II. Media Injection and Pretreatment Stage
[0061] Chemical filling: Liquid deodorant (such as plant extract or microbial agent) is injected through the inlet pipe 18 (DN25, with threaded cap) at the top of the storage tank 17. The liquid level sensor (accuracy ±5mm) monitors in real time. When the liquid level reaches 80% of the storage tank volume (about 20L), the indicator light is automatically triggered to prevent overflow.
[0062] Clean water supply: Open the inlet valve 22. Municipal tap water or treated reclaimed water enters the mixing tank 21 after passing through the filter 23 (40μm stainless steel filter screen, filtration efficiency ≥98%) to remove impurities such as mud and rust. The water level continues until it reaches 70% of the mixing tank volume (about 35L). The water level sensor will then close the inlet valve.
[0063] III. Drug Mixing and Circulation Stage
[0064] Mixing and Proportioning: The PLC controller (response time ≤ 0.5s) starts the first pump 20 (diaphragm metering pump, flow range 0.5~5L / h, accuracy ±1%), which delivers the medicine in the storage tank 17 to the mixing tank 21 through the discharge pipe 19 (Φ10mm food-grade hose). At the same time, the water inlet pipe 22 adds a small amount of water, achieving a dynamic mixing ratio of medicine and clean water according to the preset ratio (1:10 to 1:50, adjustable via the control panel).
[0065] Homogenization: Driven by the second pump 24 (centrifugal, 15m head, 20L / min flow rate), the mixture enters the drain pipe 4. 30% of the flow rate flows back to the mixing tank 21 via the return pipe 8 (Φ15mm, with a check valve), forming a clockwise vortex (flow velocity 0.8m / s) within the tank. This ensures a mixing homogeneity of ≥99% between the reagent and water, preventing stratification during static mixing (traditional static mixing only achieves 75% homogeneity). The circulation process continues for 2-3 minutes until the mixture concentration stabilizes.
[0066] IV. Spraying Deodorization Operation Stage
[0067] Pressure build-up: After the cycle is completed, the solenoid valve on the return pipe 8 is closed, and the second pump 24 pumps the full volume of the mixture into the drain pipe 4 (working pressure 0.3~0.5MPa), which is then distributed to each nozzle unit 6 (500mm spacing, 4~8 units, which can be increased or decreased as needed) through the manifold 5 (Φ32mm, material 304 stainless steel).
[0068] 3D spraying: The mixed liquid enters the nozzle body 25 through nozzle connector 26 (NPT1 / 4 tapered pipe thread, sealing pressure ≥1MPa). The first spray hole 27 (0.3mm in diameter, 6 holes) at a 45° angle on the side forms a fan-shaped mist curtain (diffusion angle 60°), covering a horizontal radius of 3m. The second spray hole 28 (0.5mm in diameter, 4 holes) at the bottom sprays vertically downwards, forming a columnar mist stream (range 2m) that reaches the surface of the garbage. The atomized droplets with a particle size of 10~40μm are suspended in the air for ≥30 minutes, fully contacting odor molecules such as hydrogen sulfide and ammonia (reaction rate ≥0.8g / h), achieving deodorization through neutralization, oxidation, and other processes (deodorization rate ≥90%).
[0069] Dynamic adjustment: If an odor sensor (detection range 0~200ppm) is installed, the concentration data can be fed back in real time. The PLC automatically adjusts the frequency of the second pump (30~50Hz) to change the spray volume. When the concentration exceeds the standard, the flow rate is automatically increased by 20%, and the energy saving and deodorization effect are dynamically balanced.
[0070] V. Shutdown and Maintenance Phase
[0071] Shutdown procedure: After the operation is completed (the duration of a single operation is adjustable from 10 to 30 minutes), turn off the second pump 24, open the drain valve (DN20) at the bottom of the mixing tank 21 to drain the residual liquid, and then start the first pump 20 to backwash the discharge pipe 19 (for 30 seconds) to prevent the crystallization of residual chemicals.
[0072] Equipment reset: Rotate screw 10 counterclockwise to raise support leg 12 to its original position (≥50mm from the ground), move caster 3 to the ground, and push the equipment to the storage area.
[0073] Routine maintenance: Disassemble nozzle unit 6 weekly (simply rotate nozzle connector 26, time ≤30 seconds) and backflush the first nozzle 27 and the second nozzle 28 with 0.2MPa clean water; replace filter 23 monthly (clamp-on design, replacement time ≤2 minutes); check the lubrication of screw 10 threads quarterly and add lithium-based grease (NLGI2 grade).
