Description

Technical Field

[0001] This utility model relates to the field of pallet fumigation technology, specifically to a pallet fumigation treatment device. Background Technology

[0002] Pallets generally refer to wooden boards used for packaging, padding, supporting, and reinforcing goods, such as wooden pallets. Pallet fumigation is a method of pest control treatment for pallets. In international trade, to prevent insects and other harmful organisms on pallets from being brought to the destination country and thus harming the local ecosystem, pallets are fumigated. Currently, chemical fumigation is commonly used, primarily to kill insects and other organisms that may harm trees and the ecosystem of the country from which the timber is imported.

[0003] During fumigation, chemicals such as methyl bromide and ethylene oxide are commonly used. This method has the following disadvantages: 1. Environmental pollution: The chemicals used in the fumigation process may pollute the environment, especially if the emission of chemicals is not completely controlled during the process. 2. Potential health risks: Operators may inhale or come into contact with toxic chemicals during fumigation if they do not take appropriate protective measures, which may have adverse health effects. 3. Residue issues: Chemical residues may remain on the fumigation trays after treatment, which may affect subsequent use, especially in food or medical product packaging, where such residues may pose safety hazards. 4. Unstable effectiveness: The effectiveness of the fumigation may be affected by environmental factors such as temperature and humidity, which may lead to inconsistent fumigation results and sometimes fail to completely eliminate harmful organisms. 5. Resistance issues: Long-term use of the same fumigation agent may lead to resistance in harmful organisms, thereby reducing the effectiveness of the fumigation. Utility Model Content

[0025] Reference Figures 1-3A pallet fumigation treatment device includes a shell 1, also called a box, outer shell, or kiln body, etc. Openable doors 2 are installed at both ends of the shell 1 to facilitate pallet entry from one end and exit from the other. A fumigation chamber 3 for placing the pallets is provided inside the shell 1. An air duct 4 is installed inside the fumigation chamber 3, with both ends of the air duct 4 connected to the fumigation chamber 3. A heating and ventilation assembly 5 is installed inside the air duct 4, including a circulating fan 50 and electric heaters 51 correspondingly installed on both sides of the circulating fan 50. A dehumidification window 6, also called a dehumidification pipe or dehumidification outlet, is installed on the top of the shell 1 for dehumidification. Window 6 is connected to fumigation chamber 3. A cover 60 that can be opened and closed is installed on the dehumidification window 6. By opening the cover 60, the high temperature and high humidity gas in fumigation chamber 3 can be discharged to the outside. It also includes a steam generator 7, which is a device that converts water into steam. By heating the water to the boiling point and generating steam, it is used to regulate the humidity in fumigation chamber 3. Steam generator 7 can deliver steam to fumigation chamber 3, which can enhance the fumigation effect, soften the wood, and shorten the processing time. The efficient, uniform and environmentally friendly processing process achieved by steam delivery ensures the safety and reliability of wooden packaging materials.

[0026] In use, the pallet-loaded cart is fed into the fumigation chamber 3 through door 2 at one end of the feeding area. Door 2 is then closed to create a sealed area within the fumigation chamber 3. The circulating fan 50 and electric heater 51 are then activated to heat the fumigation chamber 3 and the pallets. Because electric heaters 51 are symmetrically installed at both ends of the circulating fan 50, the heating speed is faster and more uniform. The circulating fan 50 circulates air through the air duct 4, the fumigation chamber 3, and the gaps between the pallets, further improving the heating speed and the uniformity of heating. During fumigation, the temperature inside the fumigation chamber 3 can be maintained at approximately 68 degrees Celsius for about 4 hours to ensure that the pallets are free of eggs, larvae, and adults of pests and diseases. The heating temperature and duration can be adjusted according to the thickness of the pallets. After fumigation, the pallet-loaded cart is removed from the fumigation chamber 3 through door 2 at one end of the discharging area. The door 2 and the feeding / discharging design prevent contamination of the processed pallets.

[0027] In some embodiments, the air duct 4 includes a horizontally installed air vane 40, which is mounted on the upper end of the fumigation chamber 3 via a bracket 41. An installation space is formed between the air vane 40 and the top wall of the fumigation chamber 3 for installing the heating and ventilation assembly 5 and for air passage. The left and right ends of the air vane 40 are sealed and fixed to the left and right inner walls of the fumigation chamber 3, allowing air to circulate in a fixed direction. The front and rear ends of the air vane 40 form ventilation spaces with the front and rear inner walls of the fumigation chamber 3, facilitating air flow between the air duct 4 and the fumigation chamber 3. This structure provides fast heating and more uniform heating.

[0028] In some embodiments, a spray tower 8 installed outside the housing 1 is also included to provide water; a spray pipe 9 is installed in the fumigation chamber 3 at the lower end of the air duct 4, and a plurality of spray holes are arranged side by side on the spray pipe 9, and one end of the spray pipe 9 is connected to the spray tower 8; when a fire occurs in the fumigation chamber 3, the liquid in the spray tower 8 can be sprayed onto the card plate through the spray pipe 9 to achieve the function of cooling and fire extinguishing.

[0029] In some embodiments, there are multiple heating and ventilation components 5 arranged side by side to improve the heating speed and air circulation speed; a row of wet windows 6 is installed at both ends of each heating and ventilation component 5 to accelerate the dehumidification speed.

[0030] In some embodiments, the power of the circulating fan 50 is 2.2 kW, and the power of the electric heater 51 is 9 kW; this increases the heating speed and the airflow speed.

[0031] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments have been described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
