Description

Technical Field

[0001] This invention relates to the field of garbage compactor technology, and in particular to a garbage compactor device for preventing the spread of odors. Background Technology

[0002] Garbage compactors are core equipment for urban waste collection and transportation. They reduce the volume of garbage through a compaction mechanism in the truck bed, significantly improving transportation efficiency. However, during the loading, compaction, and transportation of garbage, odorous gases such as hydrogen sulfide, ammonia, and volatile organic compounds produced by garbage decomposition can easily diffuse into the surrounding environment through gaps in the truck bed or the unloading port, causing serious air pollution and affecting the health of operators and the urban environment.

[0003] In existing technologies, some garbage compactors place adsorbent materials such as activated carbon inside the truck compartment to treat odors. However, this method has significant drawbacks: First, the adsorbent materials are directly exposed inside the compartment and are easily covered by garbage debris or soaked in leachate, leading to a rapid decline in adsorption efficiency and failing to achieve targeted odor collection. Second, the adsorption and neutralization processes lack temperature control; the reaction efficiency of most odor neutralizing agents is strongly correlated with temperature, making it difficult to meet the treatment needs of different odor concentrations at a fixed temperature. Therefore, there is an urgent need to design an odor diffusion prevention device for garbage compactors. Summary of the Invention

[0004] The purpose of this invention is to provide a device for preventing the spread of odors in garbage compactors, thereby overcoming the shortcomings of existing technologies.

The system includes: a location setting for the odor neutralization module; an odor sensor installed inside the vehicle compartment to detect the odor concentration; and a control module electrically connected to the temperature regulation module and the odor sensor. The control module pre-stores an adjustment curve, which is a mapping curve between odor concentration and temperature. This adjustment curve is used to dynamically adjust the operating temperature of the temperature regulation module based on the odor concentration detected by the odor sensor and historical concentration change trends. Specifically, when the odor concentration is greater than a preset threshold, the operating temperature is adjusted to a first temperature; when the odor concentration is less than the preset threshold, the operating temperature is adjusted to a second temperature, which is lower than the first temperature. Furthermore, the control module can adaptively correct the preset threshold based on the concentration change rate detected three consecutive times.

[0020] See Figures 1 to 7 This invention provides a device for preventing odor diffusion in a garbage compactor truck, comprising a chassis 100, a truck body 200, an odor collection trough 203, a barrier plate 204, an odor neutralization module 207, a temperature regulation module 208, an odor sensor 209, and a control module 210. The truck body 200 is welded and fixed above the chassis 100, serving as the core cavity for garbage loading and compaction. The control module 210 is integrated into an electrical control box on the outside of the truck body 200, used for automated control of the entire device.

[0021] In this embodiment, the carriage 200 is a rectangular sealed cavity, and its inner walls are, in a clockwise direction, a first wall 201, a second wall, a third wall 202, and a fourth wall. The first wall 201 and the third wall 202 are opposite side walls, and the second and fourth walls are opposite front and rear walls. On the inner sides of the first wall 201 and the third wall 202, a long strip-shaped odor collection trough 203 is formed along the vertical direction of the wall height. The opening of the trough faces the inner cavity of the carriage 200, ensuring that odorous gases inside the carriage 200 can naturally flow into the trough.

[0022] The bottom of the odor collection tank 203 is provided with a drainage slope 2031 along the length of the vehicle body 200, i.e., the forward and backward direction of the vehicle's movement. The drainage slope 2031 has an inclined structure, and a drain pipe 2032 is welded to its bottom end. A solenoid valve 2033 is installed on the drain pipe 2032. A liquid collection tank 2034 is fixed to the chassis 100 by bolts. The other end of the drain pipe 2032 is connected to the liquid collection tank 2034 to collect condensate or leachate accumulated in the tank. The solenoid valve 2033 is electrically connected to the control module 210. The control module 210 can control the opening and closing of the solenoid valve 2033 according to the odor concentration detected by the odor sensor 209: when the odor concentration is continuously higher than a preset threshold, it is determined that liquid may be accumulating in the tank, causing a decrease in neutralization efficiency. The control module 210 drives the solenoid valve 2033 to open, draining the liquid into the collection tank; after the liquid is drained, the solenoid valve 2033 closes to ensure the tank's sealing.

[0023] In addition, the bottom of the odor collection tank 203 is equipped with multiple exhaust ports, which correspond to the hollow channels inside the tank to discharge the neutralized gas. A one-way breathable membrane is attached to the exhaust ports, allowing gas to escape only from inside the tank and preventing outside air or impurities from entering in reverse.

[0024] In this embodiment, a baffle plate 204 is embedded in the opening of the odor collection tank 203. The baffle plate 204 is fixed to the edge of the tank by bolts, and an anti-clogging protrusion 2041 is integrally formed on the side facing the inner cavity of the compartment 200. The anti-clogging protrusion 2041 is arranged around the first opening 205 on the baffle plate 204 and is shaped like a frustum of a cone, which can effectively prevent garbage debris from clogging the first opening 205. Three parallel positioning ribs are provided on the side of the baffle plate 204 away from the inner cavity of the compartment 200. The positioning ribs are fitted with the inner wall of the odor collection tank 203 with a clearance, which not only ensures the installation stability of the baffle plate 204, but also reserves space for gas flow.

[0025] A receiving area 206 is formed between the barrier plate 204 and the odor collection tank 203. The receiving area 206 is uniformly filled with an odor neutralizing module 207. Preferably, the odor neutralizing module 207 is a block-shaped solid odor neutralizing block. The solid odor neutralizing block is made of a composite material of activated carbon loaded with an alkaline adsorbent, which is tightly attached to the inner sidewall of the barrier plate 204 to ensure that the odor gas flowing through the first opening 205 can come into contact with the neutralizing agent.

[0026] In one preferred embodiment, a breathable skeleton 2071 is embedded inside the solid odor neutralizing block. The breathable skeleton 2071 can have a honeycomb structure and can be made of polypropylene. The breathable skeleton 2071 forms a continuous hollow channel. One end of the hollow channel is directly opposite the first opening 205 of the barrier plate 204, which is used to guide the odor gas to enter from the opening and pass through the neutralizing agent along the channel, thereby improving the contact efficiency.

[0027] In another preferred embodiment, the temperature regulation module 208 includes a mounting base 2081, a temperature sensor 2082, and an electric heating wire 2083. The mounting base 2081 is slidably connected to the outer wall of the carriage 200 via a slide rail. Additionally, the distance between the mounting base 2081 and the odor collection tank 203 can be adjusted. The electric heating wire 2083 is embedded in the side of the mounting base 2081 facing the carriage 200. The temperature sensor 2082 is embedded in the side wall of the odor collection tank 203 and is in contact with the neutralizing agent. Both the electric heating wire 2083 and the temperature sensor 2082 are electrically connected to the control module 210. The temperature sensor 2082 detects the temperature of the neutralizing agent area in real time and feeds it back to the control module 210. The temperature regulation module 208 can be configured with four sets, for example, two sets each of the first wall surface 201 and the third wall surface 202, which are movably mounted on the outer wall of the carriage 200 via slide rails and correspond to the positions of the odor collection tank 203.

[0028] In this embodiment, the odor sensor 209 is a metal-oxide-semiconductor sensor. Preferably, three odor sensors 209 are installed, located in the feed inlet, compression chamber and discharge outlet areas of the compartment 200, respectively. The sensor probes extend into the interior of the compartment 200, and the outer shell is waterproof and dustproof. They are used to detect the odor concentration in different areas of the compartment 200 in real time and transmit the concentration signal to the control module 210. The specific working principle is as follows: First, the control module 210 stores a preset threshold for odor concentration, such as 50 ppm. When the concentration detected by the odor sensor 209 is greater than the preset threshold, the control module 210 drives the electric heating wire 2083 to heat up to the first temperature, thereby improving the reaction efficiency of the solid odor neutralizing block. The first temperature can be 45 degrees Celsius. When the concentration detected by the odor sensor 209 is less than the preset threshold, the control module 210 drives the electric heating wire 2083 to cool down to the second temperature, such as 25 degrees Celsius, thereby reducing energy consumption. The temperature sensor 2082 provides real-time feedback on the tank temperature. If the temperature exceeds the upper limit of the first temperature, such as 50 degrees Celsius, the control module 210 automatically cuts off the power supply to the electric heating wire 2083 to prevent overheating and damage to the neutralizing agent.

[0029] Furthermore, the control module has a pre-stored adjustment curve, which is a mapping curve between odor concentration and temperature. This curve is used to dynamically adjust the operating temperature of the temperature control module based on the odor concentration detected by the odor sensor and its historical trend. Specifically, when the odor concentration is greater than a preset threshold, the operating temperature is adjusted to a first temperature; when the odor concentration is less than the preset threshold, the operating temperature is adjusted to a second temperature, which is lower than the first temperature. The control module can also adaptively correct the preset threshold based on the concentration change rate detected three consecutive times. In detail, this adjustment curve is a non-linear curve. As another preferred embodiment, the control module 210 has a reserved CAN bus interface, which can communicate with the vehicle control system of the garbage compactor. When the garbage compaction mechanism is started, the odor concentration during the compaction operation increases sharply. The vehicle system sends a signal to the control module 210 of this device to preheat the electric heating wire 2083 to the first temperature, so as to realize the linkage prediction.

[0030] The working process of this embodiment is as follows: When garbage is loaded into the compartment 200 and compressed, odorous gas enters the odor collection tank 203 from the inner cavity of the compartment 200, passes through the hollow channel of the solid odor neutralizing block, and is adsorbed and neutralized after fully contacting the neutralizing agent; the treated gas is discharged through the exhaust port at the bottom of the tank, and the accumulated liquid enters the liquid collection tank 2034 through the drainage slope 2031 and the drain pipe 2032. The odor sensor 209 detects the odor concentration in real time, and the control module 210 dynamically adjusts the temperature of the electric heating wire 2083 according to the concentration to ensure that the neutralization efficiency is adapted to the odor intensity, ultimately achieving efficient interception and treatment of odor in the compartment 200, preventing it from spreading to the outside world, and effectively solving the shortcomings of the prior art.
