Description

Technical Field

[0001] This utility model relates to the field of waste transfer technology, and in particular to a spray system for a kitchen waste transfer vehicle. Background Technology

[0002] As people's living standards improve, the amount of kitchen waste generated is increasing daily. During transportation, kitchen waste, due to its high organic content, is prone to decay and deterioration, producing large amounts of foul odors such as hydrogen sulfide and ammonia. These odors not only pollute the surrounding environment but also harm human health. Furthermore, after kitchen waste accumulates in the truck bed, a large amount of residue and stains adhere to the interior walls after unloading. If not cleaned promptly, this residue can breed bacteria and insects, further exacerbating environmental pollution.

[0003] For cleaning the cargo compartments after unloading, manual cleaning or simple high-pressure water gun rinsing is usually used. The cleaning efficiency is low, and the wastewater after cleaning is directly discharged, which not only wastes water resources but also causes secondary pollution to the environment.

[0040] To better explain and facilitate understanding of this utility model, a detailed description of its specific embodiments is provided below with reference to the accompanying drawings. In this document, directional terms such as "upper," "lower," etc., are used interchangeably with other directional terms. Figure 1 The orientation is used as a reference.

[0041] While exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0042] like Figure 1As shown, this utility model provides a spray system for a kitchen waste transfer vehicle, installed on the vehicle compartment 1. After unloading, the system sprays water into the compartment 1 to rinse it, or sprays deodorizing agent onto the surface of the waste during transport to eliminate odors. The spray system includes a liquid supply device, a wastewater treatment device, and multiple spray devices. The wastewater treatment device includes a wastewater collection mechanism located at the bottom of the compartment 1 and a wastewater treatment mechanism connected to the collection mechanism. The wastewater treatment mechanism is connected to the liquid supply device. The wastewater, including sprayed water and seepage during waste transport, is collected at the bottom of the compartment 1 by the wastewater collection mechanism and then returned to the liquid supply device after treatment, achieving water recycling, improving water resource utilization efficiency, and preventing secondary pollution from direct wastewater discharge. The liquid supply device is located outside the compartment 1, and multiple spray devices are located on the inner top surface of the compartment 1, spaced apart along its length. All spray devices are connected to the liquid supply device via pipes. The water jets from multiple sets of spray devices spaced along the length of the carriage 1 can effectively cover the entire inner side of the carriage 1, thereby efficiently cleaning the inner side of the carriage 1, avoiding dirt residue, effectively improving cleaning efficiency, and thus improving the working efficiency of the kitchen waste transfer vehicle.

[0043] like Figure 2 As shown, each spraying device includes a mounting base 7 and multiple nozzle mechanisms. The mounting base 7 is fixedly installed on the inner top surface of the transfer vehicle compartment 1. The multiple nozzle mechanisms are arrayed on the mounting base 7, with the nozzle mechanisms facing the floor of the compartment 1. Further, the nozzle mechanism includes a drive assembly 8, a first nozzle assembly 9, and a second nozzle assembly 10. The drive assembly 8 is connected to the mounting base 7. The first nozzle assembly 9 and the second nozzle assembly 10 are both mounted on the drive assembly 8. The first nozzle assembly 9 and the second nozzle assembly 10 are both connected to a liquid supply device through pipes. The liquid supply device simultaneously supplies liquid to the multiple first nozzle assemblies 9 and the multiple second nozzle assemblies 10 of each spraying device.

[0044] The first nozzle assembly 9 includes a mounting block 92 and multiple jet nozzles 91. The mounting block 92 is mounted on a drive assembly 8, which drives the mounting block 92 to rotate about an axis perpendicular to the top surface of the carriage 1. The first surface of the mounting block 92 has multiple mounting holes, and each jet nozzle 91 is connected to one of these holes, with the nozzles communicating with each hole, thus serving as part of the liquid delivery conduit for the nozzles. The mounting holes are connected to a liquid supply device via a first conduit, on which a first solenoid valve is installed. Specifically, the mounting block 92 has a main channel, and the mounting holes communicate with this main channel, which in turn communicates with the first conduit. Liquid supplied by the liquid supply device passes sequentially through the first conduit, the main channel, and the mounting holes before entering the multiple jet nozzles 91. The mounting block 92 drives the multiple jet nozzles 91 to rotate, using high-pressure water to flush away residue and stains from the inner wall of the carriage 1. This rotation enhances the cleaning effect and improves cleaning efficiency.

[0045] like Figure 3 As shown, the first surface of the mounting block 92 is an arc surface, and multiple mounting holes are arranged radially along the arc surface to form a wide-angle fan-shaped nozzle with an angle of 80 to 120 degrees. In the flushing mode, the high-pressure water jet has a large range and diffusion angle. Combined with the rotation function, it can better cover the side wall of the carriage 1.

[0046] The second nozzle assembly 10 includes an atomizing nozzle 101 and an odor concentration sensor 102. The atomizing nozzle 101 is mounted on the rotating part of the drive assembly 8, and the odor concentration sensor 102 is mounted on the fixed part of the drive assembly 8. The atomizing nozzle 101 and the jet nozzle 91 are symmetrically arranged about the rotation axis of the jet nozzle 91. The atomizing nozzle 101 is connected to the liquid supply device through a second pipe, on which a second solenoid valve is installed. The odor concentration sensor 102 is used to acquire the odor concentration value and is connected to the controller. Multiple odor concentration sensors 102 at different locations monitor the odor concentration at different locations within the compartment 1 in real time, achieving accurate odor concentration collection within the compartment 1. The atomizing nozzle 101 atomizes the deodorizing agent and sprays it evenly onto the surface of the kitchen waste for deodorization. Atomization expands the coverage area and improves deodorization efficiency. See also Figure 4Each second nozzle assembly 10 includes multiple atomizing nozzles 101, which are integrated and mounted on a flat panel. The atomizing nozzles 101 feature an anti-clogging design with an aperture not exceeding 0.3mm. The deodorizing agent is sprayed into the compartment 1 to deodorize the environment. The deodorizing agent used in this device is an environmentally friendly agent, such as biological enzymes or plant extracts, which only neutralizes or decomposes odor molecules (such as hydrogen sulfide and ammonia), does not react harmfully with the organic components of kitchen waste, and will not negatively impact subsequent waste treatment (such as composting or anaerobic digestion). The sprayed agent flows with the spray liquid (or natural leachate) into the wastewater collection mechanism at the bottom of the compartment 1. After filtration and deodorization by the wastewater treatment mechanism, it flows back to the liquid supply device, eliminating the need for an additional collection device.

[0047] In a preferred embodiment, the drive component 8 is a conventional motor, which is fixed on the mounting base 7 by a mounting bracket. The motor shaft is connected to a reducer, which drives an infusion tube to rotate through conventional structures such as gears and shafts. The infusion tube has two channels inside, which are respectively connected to the atomizing nozzle 101 and the jet nozzle 91. The connection method is a rotational connection, that is, a part of the infusion tube is fixed, and two first channels are opened inside, which are respectively connected to the first pipe and the second pipe. The other part of the infusion tube rotates to install the atomizing nozzle 101 and the jet nozzle 91. It also has two second channels inside, and the two first channels are rotatably connected to the two second channels one by one.

[0048] In a preferred embodiment, six sets of spray devices are installed along the length of the carriage 1 to avoid incomplete spray coverage in the narrow carriage 1. The spray devices are installed on the top of the carriage 1. The design must consider the loading safety distance. When loading kitchen waste, it usually accumulates at the bottom of the carriage 1, leaving sufficient space at the top. Generally, the height of the carriage 1 is greater than or equal to 2 meters, while the loading height cannot exceed 1.5 meters, which can prevent the waste from directly contacting the top equipment. During unloading, the waste is poured from the rear or side of the carriage 1. The top equipment does not participate in the unloading process, and the flushing mode is activated after unloading. At this time, there is no waste in the carriage 1, further avoiding the risk of scratches.

[0049] like Figure 1As shown, the liquid supply device includes a water tank 3, a reagent tank 2, a high-pressure water pump 6, and a two-position three-way solenoid valve. The water tank 3 and reagent tank 2 are respectively connected to the inlet of the two-position three-way solenoid valve via pipelines. The outlet of the two-position three-way solenoid valve is connected to the inlet of the high-pressure water pump 6. The first and second pipelines are connected to the outlet of the high-pressure water pump 6 via a three-way connection. The first and second solenoid valves control the opening and closing of the first and second pipelines. The high-pressure water pump 6 is a conventional booster pump. When the carriage 1 needs to be rinsed after unloading, the system starts the rinsing mode. The two-position three-way solenoid valve connects to the water tank 3, the first solenoid valve opens, and the second solenoid valve closes. The high-pressure water pump 6 delivers water from the water tank 3 to each first nozzle assembly 9. Simultaneously, the mounting block 92 rotates under the drive of the motor, and multiple jet nozzles 91 perform high-pressure rinsing on the side walls of the carriage. The rinsed wastewater is collected by the wastewater collection mechanism at the bottom of the carriage 1 and enters the wastewater treatment mechanism. After filtration and deodorization by the wastewater treatment mechanism, the wastewater flows back to the water tank 3, realizing the recycling of water resources. When the transfer vehicle transports kitchen waste, the system enters spray mode. Odor concentration sensor 102 monitors the odor concentration inside the transfer vehicle compartment 1 in real time. When the detected value by odor concentration sensor 102 exceeds the set value, a two-position three-way solenoid valve connects to the agent tank 2, opening the second solenoid valve and closing the first solenoid valve. Simultaneously, the high-pressure water pump 6 is activated, and the deodorizing agent in agent tank 2 is delivered to each second nozzle assembly 10 via the high-pressure water pump 6. The atomizing nozzles 101 spray the kitchen waste inside the compartment, improving the uniformity and effectiveness of the spray. During the spraying process, when odor concentration sensor 102 detects that the odor concentration inside compartment 1 has decreased below the set value, the high-pressure water pump 6 stops, and the spraying stops. When odor concentration sensor 102 detects that the average odor concentration inside compartment 1 has risen above the set value, the high-pressure water pump 6 is restarted, and the spraying mode is entered again, thus cycling continuously.

[0050] like Figure 5 As shown, the sewage collection mechanism includes a collection plate 12 and a collection trough 13. The collection plate 12 is installed on the floor of the carriage 1, covering the floor of the carriage 1. The collection trough 13 is installed along the edge of the carriage 1, and the collection trough 13 is connected to the collection plate 12 as an integral structure. The bottom of the collection trough 13 is lower than the level of the collection plate 12. In other embodiments, the collection trough 13 can also be directly installed on the edge of the floor of the carriage 1, with the bottom of the collection trough 13 lower than the level of the floor of the carriage 1. The collection trough 13 is connected to the sewage treatment mechanism through a pipe. After flushing, the sewage is collected by the collection trough 13 and flows into the sewage treatment mechanism by gravity through the pipe. The collection trough 13 can also collect leachate in real time and let it flow into the sewage treatment mechanism by gravity through the pipe, avoiding sewage stagnation in the carriage 1.

[0051] Furthermore, the wastewater treatment unit includes a support base 16, a tank 4, and a filter assembly 14 and a deodorization assembly 15 detachably installed inside the tank 4. The support base 16 is located outside the carriage 1, and the tank 4 is vertically mounted on the support base 16. The tank 4 is vertically mounted, with an inlet at its upper end, which communicates with a collection tank 13. The upper level of the tank 4 is lower than the bottom level of the collection tank 13, allowing wastewater in the collection tank 13 to flow into the tank 4 by gravity. The lower end of the tank 4 has a drain outlet, which communicates with a water tank 3. The tank 4 is mounted via the support base 16, and its horizontal height is higher than that of the water tank 3, allowing water in the tank 4 to flow smoothly into the water tank 3, thus achieving water circulation. A filter assembly 14 and a deodorization assembly 15 are sequentially installed between the inlet and outlet. Wastewater or leachate from rinsing is collected in a collection trough 13 at the bottom of the compartment 1 and flows into the tank 4 through a pipe. The wastewater is filtered by the filter assembly 14 and then deodorized by the deodorization assembly 15. Preferably, the filter assembly 14 is a filter screen, and the deodorization assembly 15 is activated carbon. The wastewater treatment system is designed for wastewater generated from spraying and rinsing, as well as leachate from kitchen waste. The main pollutants are solid residues (such as food scraps and silt) and water-soluble odor components (such as hydrogen sulfide and ammonia). The filter assembly 14 removes larger solid impurities through the filter screen, and the deodorization assembly 15 adsorbs odor molecules dissolved in the water through activated carbon. The treated water quality meets the water standards for rinsing the compartment 1, requiring only the absence of obvious impurities and strong odors. In practical applications, the activated carbon can be replaced and the filter screen cleaned periodically to ensure long-term treatment effectiveness.

[0052] The kitchen waste transfer vehicle's spray system also includes a controller, with both the spraying device and the liquid supply device electrically connected to the controller. Specifically, the driver's cab of the transfer vehicle is equipped with a controller, a mode switching button, and indicator lights. The mode switching button allows the driver to switch between spraying and rinsing modes from inside the cab, while the indicator lights use color changes to show the system's current mode status. The odor concentration sensor 102, motor, high-pressure water pump 6, two-position three-way solenoid valve, first solenoid valve, second solenoid valve, mode switching button, and indicator lights are all electrically connected to the controller. When the transfer vehicle is transporting kitchen waste, the driver presses the button in the cab; the indicator light turns green, and the system enters spraying mode. When the transfer vehicle has finished unloading, the driver presses the button again; the indicator light turns red, and the system enters rinsing mode.

[0053] The spray system controls the spraying and rinsing operations inside the truck compartment 1 by setting the high-pressure water pump 6 to operate in different modes. The second nozzle assembly 10 can spray kitchen waste inside the truck compartment 1 from different directions, improving the uniformity and effectiveness of the spraying. An odor concentration sensor 102 monitors the odor concentration inside the truck compartment in real time. Based on the real-time odor concentration value inside the truck compartment 1, the controller can control the operation of the second solenoid valve and the two-position three-way solenoid valve, thereby achieving intelligent control of the spray system and improving the spraying effect and the utilization rate of the spraying agent. The controller also controls the operation of the high-pressure water pump 6, the two-position three-way solenoid valve, and the first and second solenoid valves to switch between spraying and rinsing modes. The wastewater treatment device enables water recycling, improving water resource utilization efficiency. Furthermore, the multiple sets of spray devices and sensors address the issue of the excessive length of the transport truck compartment 1, further improving the spraying effect.
