Description

Technical Field

[0001] This invention relates to the field of disease prevention and control technology, specifically to a wood disease prevention and control device. Background Technology

[0002] Pine wilt disease (Bursaphelenchxylophilus) is a devastating forest disease caused by the pine wilt nematode. It is a major invasive alien species in my country and has been listed as a quarantine pest for forest plants both domestically and internationally. Since its first discovery and report at the Sun Yat-sen Mausoleum in Nanjing in 1982, pine wilt disease has spread to 21 provinces, municipalities, and autonomous regions across the country, infecting approximately 1.3 million hectares of natural or planted pine forests, including Masson pine, Huangshan pine, Yunnan pine, red pine, oil pine, black pine, and slash pine. This has caused severe damage to my country's pine forest resources, natural landscapes, and ecological environment. A total of 600 million pine trees have died nationwide due to pine wilt disease, resulting in direct and indirect economic losses exceeding 100 billion yuan.

[0003] According to the "Management Measures for Pine Wilt Disease-Infected Wood" and the "Technical Program for the Prevention and Control of Pine Wilt Disease" issued by the National Forestry and Grassland Administration, the main methods for treating pine wilt disease-infected wood are currently burning, crushing, or rotary cutting. While these methods can control the risk of disease transmission to some extent, they have the following drawbacks and shortcomings:

[0004] First, the processing costs are high and resources are wasted. Methods such as incineration, crushing, or rotary cutting prevent infected timber from entering the market in its original log form, completely wasting its economic value. The processing costs far exceed the value of the infected timber itself, placing significant pressure on local finances.

[0005] Second, it is energy-intensive and produces large amounts of carbon emissions. Incineration generates large quantities of greenhouse gases such as carbon dioxide, which does not meet the requirements of green and low-carbon development, and also poses a risk of forest fires.

[0006] Third, there is a high risk of the loss of infected timber. Because infected logs have certain economic value, under the current policy requirement that they can only be burned, crushed, or rotary-cut, infected log harvesters and timber processors illegally harvest, transport, and process infected logs that have not undergone pest control treatment in order to obtain economic benefits, which exacerbates the risk of the spread of the disease.

[0007] Current microwave treatment technologies lack precise control methods. In recent years, some studies have attempted to use microwave technology for pest control of infected wood. For example, research on the SWB-II tunnel-type microwave pest control equipment has shown that a wood surface temperature greater than 68℃ for 30 minutes can effectively kill pine sawyer beetles and pine wood nematodes. However, current microwave treatment technologies only use temperature, time, or power as single control indicators, failing to comprehensively consider the coupling relationship between wood type (logs and timber), wood weight, treatment time, microwave power, and temperature rise. This results in unstable treatment effects, high energy consumption, and difficulty in achieving precise control for different types of infected wood. Furthermore, when treating large logs, existing microwave treatment equipment often suffers from uneven heating and low treatment efficiency due to the negative effect of the bark on microwave conduction and the large diameter of the logs leading to low efficiency in heat transfer from the surface to the interior.

[0029] A treatment method using any of the above-mentioned wood pest control and disinfection equipment includes the following steps:

[0030] S1: Obtain the wood type information and single processing weight M of the infected wood to be treated. The wood type includes logs and square timber.

[0031] S2: Based on the wood type information and the weight M of a single treatment, determine the target energy coefficient K value range, wherein the energy coefficient K is calculated according to the following formula:

[0032]

[0033] in, For microwave processing time, For microwave processing power, The weight of infected wood processed in a single session. The temperature change of the infected wood before and after treatment;

[0046] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0047] 1. By setting up an elastic semi-metallic spherical cover, the top of which is higher than the bearing surface of the log carriage, it can provide auxiliary support for the middle of the infected log after the log carriage moves past, effectively preventing large logs from rolling or shifting due to their own weight during microwave treatment, thus ensuring the stability and safety of the treatment. At the same time, the elastic semi-metallic spherical cover forms a circumferential reflection structure for the microwave emitted by the magnetron, which can reflect the microwave emitted by the bottom magnetron to the bottom and sides of the infected log, making up for the defect that the bottom of the infected log is difficult to be directly irradiated by microwaves, and achieving uniform heating of the infected log.

[0048] 2. By setting multiple elastic semi-metallic spherical covers to a structure in which the height gradually decreases from the middle to both ends of the connecting crossbeam, a graded load-bearing structure for the infected wood is formed, which can adapt to the support requirements of infected wood of different diameters; at the same time, a graded microwave reflection structure is formed, realizing graded microwave radiation to different height areas of the infected wood, further improving the heating uniformity.

[0049] 3. By setting a rotating semi-metallic convex ball on the surface of the elastic semi-metallic spherical cover, a rolling friction structure can be formed when the wood-carrying vehicle moves over it, reducing the frictional resistance between the wood and the spherical cover and avoiding damage to the surface of the wood; it can also serve as an auxiliary microwave reflection structure, expanding the microwave reflection direction and range and improving microwave utilization efficiency.

[0050] 4. By setting a structure on the semi-metallic dome where the spherical curvature gradually increases from the middle to both ends, a reflective structure with a gradually varying degree of microwave focusing is formed. This allows for differentiated microwave focusing according to the heating requirements of different parts of the wood, further optimizing the heating effect. Attached Figure Description

[0061] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0062] Example

[0063] like Figure 1-8 As shown, a wood pest control device includes a shielded box 1, a box door 2, a bottom track 3, a movable track 4, a wood-carrying cart 5, and multiple magnetrons 6.

[0064] Specifically, the shielding box 1 is made entirely of metal shielding material, and its interior contains a processing chamber. This processing chamber is used to contain the infected wood to be processed and provide a sealed space for microwave processing. The shielding effect of the shielding box 1 can effectively prevent microwave leakage and ensure operational safety. The wall thickness and material of the shielding box 1 should meet the conventional requirements for microwave shielding, and it is usually made of stainless steel or galvanized steel plate with a wall thickness of 1.5mm to 3mm.

[0065] Specifically, door 2 is installed at one end of shielded box 1 and is used to open or close the processing chamber. A sealing structure is provided between door 2 and shielded box 1. The sealing structure adopts a conductive rubber sealing strip or a finger spring shielding sealing structure to ensure that microwaves do not leak during processing. Door 2 is also provided with an observation window, which is embedded with a metal shielding mesh, so that operators can easily observe the processing status inside the chamber.

[0066] Specifically, the bottom track 3 is installed on the bottom wall of the processing chamber of the shielded box 1, extending along the length of the shielded box 1. The bottom track 3 consists of two parallel steel tracks, the surface of which has been hardened to withstand the reciprocating load of the movable track 4 and the timber cart 5.

[0067] Specifically, the movable track 4 is mounted on the bottom track 3 along the length of the shielding box 1. The bottom of the movable track 4 is provided with a slider or roller that slides and engages with the bottom track 3, so that the movable track 4 can move smoothly along the bottom track 3.

[0068] Furthermore, a rack is provided on the movable track 4, and a drive motor is installed on the bottom track 3. The output end of the drive motor is provided with a drive gear that meshes with the rack, used to drive the movable track 4 to reciprocate along the bottom track 3. The drive motor is preferably a servo motor or a stepper motor to achieve precise control of the moving speed and displacement of the movable track 4. Through the gear and rack meshing drive method, the movable track 4 can be moved smoothly and precisely, facilitating the feeding of the wood cart 5 into or out of the processing chamber.

[0069] Furthermore, both the end of the bottom track 3 closest to the door 2 and the end furthest from the door 2 are equipped with limiting blocks to restrict the extreme displacement of the movable track 4. These limiting blocks are made of elastic buffer material, preventing the movable track 4 from exceeding the range of the bottom track 3 during movement, ensuring that the movable track 4 moves back and forth within a safe travel range, thus improving the safety and reliability of the equipment operation.

[0070] Specifically, the timber cart 5 is movably connected to the movable track 4 to carry the infected timber. The timber cart 5 has a bearing surface on which the infected timber is placed and moves together. The timber cart 5 adopts a frame-type flatbed structure, with the bearing surface made of welded square tubing, featuring spaced intervals for microwave transmission. The bottom is equipped with rollers that cooperate with the movable track 4, and the rollers have locking devices. When the timber cart 5 moves to a predetermined position, the locking devices can fix its position to prevent accidental movement during processing. The bearing surface of the timber cart 5 has anti-slip structures, such as anti-slip ridges or anti-slip pads, to prevent the infected timber from rolling on the bearing surface.

[0071] Specifically, multiple magnetrons 6 are installed on the side walls of the shielded box 1, with the microwave emission direction of the magnetrons 6 facing the processing chamber. The number and arrangement of the magnetrons 6 are determined according to the size of the processing chamber and the processing requirements. As a preferred arrangement of the present invention, multiple magnetrons 6 are provided on the left and right side walls, as well as the bottom and top walls of the shielded box 1, to achieve multi-directional microwave radiation to the wood. Each magnetron 6 has a power of 1kW to 2kW and a frequency of 2.45GHz, which conforms to the conventional frequency band for industrial microwave applications.

[0072] Specifically, during the process, the infected wood to be treated is first placed on the wood-carrying cart 5, which carries the infected wood to the movable track 4. Then, the movable track 4 moves the wood-carrying cart 5 from the bottom track 3 into the processing chamber. After the chamber door 2 is closed, multiple magnetrons 6 emit microwaves to treat the infected wood. After the treatment is completed, the movable track 4 moves the wood-carrying cart 5 out of the processing chamber, and the chamber door 2 is opened to take out the treated infected wood.

[0073] Furthermore, the equipment structure with the elastic semi-metallic spherical cover is as follows:

[0074] Specifically, such as Figure 7 and Figure 8 As shown, based on the above basic equipment structure, the wood pest control and disinfection equipment provided by the present invention also includes multiple connecting beams 41 and elastic semi-metallic spherical covers 42.

[0075] Specifically, multiple connecting beams 41 are spaced apart along the width of the movable track 4, with both ends of each beam fixed to the sides of the track 4. The connecting beams 41 are made of metal with a rectangular cross-section, possessing sufficient structural strength to withstand the pressure of the elastic semi-metallic spherical cover 42 and the wooden beam. The spacing between adjacent connecting beams 41 is 100mm to 300mm, with the specific spacing determined based on the typical diameter range of the wooden beam.

[0076] Specifically, the elastic semi-metallic dome 42 is mounted on the connecting beam 41. The elastic semi-metallic dome 42 uses an elastic material as its substrate, and its surface is coated or inlaid with a semi-metallic conductive material. As an optional embodiment, the substrate is made of rubber or elastic plastic with a Shore A hardness of 50 to 80; the semi-metallic conductive material is a copper powder coating, an aluminum powder coating, or a metal foil, with a coating thickness of 0.1 mm to 0.5 mm, so that the elastic semi-metallic dome 42 has both a certain elastic deformation capability and a microwave reflection function.

[0077] Specifically, the top of the elastic semi-metallic spherical cover 42 is higher than the bearing surface of the timber carrier 5, that is, the top of the elastic semi-metallic spherical cover 42 is higher than the height of the plane where the infected timber is placed. The height of the top of the elastic semi-metallic spherical cover 42 above the bearing surface is 50mm to 200mm, and the specific height is determined according to the diameter range of the infected timber to be treated, so as to ensure that infected timber of different diameters can form effective contact with the elastic semi-metallic spherical cover 42.

[0078] Specifically, the magnetron 6 at the bottom of the shielding box 1 is located below the bearing surface of the wood-carrying cart 5. That is, the magnetron 6 at the bottom is installed on the bottom wall or side wall of the shielding box 1 near the bottom. Its microwave emission direction is upward or obliquely upward, and it covers the area of ​​the elastic semi-metallic dome 42 for microwave radiation to the bottom of the wood.

[0079] Specifically, the elastic semi-metallic dome 42 has a dual function: First, after the wood-carrying cart 5 moves past, the elastic semi-metallic dome 42 forms an auxiliary support for the middle of the infected wood through its elastic deformation, preventing the infected wood from rolling or shifting due to its own weight during microwave treatment, thus ensuring the stability and safety of the treatment; Second, the semi-metallic surface of the elastic semi-metallic dome 42 forms a circumferential reflection structure for the microwaves emitted by the magnetron 6, which can reflect the microwaves emitted from the bottom magnetron 6 to the bottom and sides of the infected wood, so that the microwaves can reach the bottom area of ​​the infected wood and achieve all-round heating of the infected wood. At the same time, the upward force exerted by multiple elastic semi-metallic domes 42 on the infected wood also forms a blocking force for the free movement of the wood-carrying cart 5.

[0080] Graded load-bearing and graded reflection structure:

[0081] Furthermore, based on the above-mentioned equipment structure with elastic semi-metallic spherical covers 42, multiple elastic semi-metallic spherical covers 42 are provided in the length direction of the connecting beam 41, and the height of the multiple elastic semi-metallic spherical covers 42 gradually decreases from the middle to both ends of the connecting beam 41.

[0082] Specifically, the elastic semi-metallic spherical covers 42 located in the middle of the connecting beam 41 have the highest height, the elastic semi-metallic spherical covers 42 located at both ends of the connecting beam 41 have the lowest height, and the elastic semi-metallic spherical covers 42 located in the middle have a height between the two. As a specific dimensional example, the top of the elastic semi-metallic spherical cover 42 in the middle of the connecting beam 41 is 150mm to 200mm above the bearing surface, and the height decreases by 20mm to 30mm every 100mm from the middle to both ends, until the top of the elastic semi-metallic spherical covers 42 at both ends of the connecting beam 41 is 50mm to 80mm above the bearing surface.

[0083] Specifically, the aforementioned height gradient setting forms a graded support structure for the infected wood: when the infected wood is placed on the wood-carrying vehicle 5, the infected wood in the middle first compresses the elastic semi-metallic spherical cover 42. After the elastic semi-metallic spherical cover 42 deforms, the elastic semi-metallic spherical covers 42 on both sides will support the infected wood, thus forming a graded auxiliary support structure in the wood-carrying vehicle 5 with a large auxiliary support force in the middle and a gradually decreasing force at the edges.

[0084] Meanwhile, the gradually varying heights of the multiple elastic semi-metallic domes 42 also form a graded reflection structure for the magnetron 6 to emit microwaves: the domes of different heights reflect microwaves to different height regions of the infected wood, realizing differentiated microwave radiation to different longitudinal positions of the infected wood, and further improving the uniformity of heating.

[0085] Furthermore, multiple elastic semi-metallic domes 42 are staggered along the length of the movable track 4. That is, at different positions along the length of the movable track 4, the elastic semi-metallic domes 42 are staggered in the width direction of the connecting beams 41. For example, on the first row of connecting beams 41, the elastic semi-metallic domes 42 are positioned on the left and right sides of the width direction of the connecting beams 41; on the adjacent second row of connecting beams 41, the elastic semi-metallic domes 42 are positioned in the middle of the width direction of the connecting beams 41; and so on. This staggered arrangement allows the infected wood to pass through multiple domes at different positions and heights in sequence during movement, achieving gradual and graded support and microwave reflection, avoiding indentations on the surface of the infected wood by the domes, and making the microwave reflection more uniformly dispersed.

[0086] Elastic semi-metallic dome structure with semi-metallic convex spheres:

[0087] Furthermore, such as Figure 7As shown, based on the above-mentioned graded bearing and graded reflection structure, the surface of the multiple elastic semi-metallic dome 42 is provided with a number of semi-metallic convex spheres 43.

[0088] Specifically, the semi-metallic convex spheres 43 protrude from the surface of the elastic semi-metallic spherical cover 42 and are also made of a semi-metallic conductive material. The diameter of the semi-metallic convex spheres 43 is 5mm to 20mm, and the height of protrusion from the surface of the elastic semi-metallic spherical cover 42 is 3mm to 10mm. The semi-metallic convex spheres 43 are distributed in an array on the surface of the elastic semi-metallic spherical cover 42, and the spacing between adjacent semi-metallic convex spheres 43 is 10mm to 30mm.

[0089] Specifically, the semi-metallic convex sphere 43 forms an extended reflection structure for the magnetron 6 to emit microwaves. The arc-shaped surface of the semi-metallic convex sphere 43 can reflect the incident microwaves in multiple directions, expanding the microwave reflection angle and coverage, and improving the microwave utilization efficiency and heating uniformity.

[0090] Furthermore, several semi-metallic protrusions 43 of the elastic semi-metallic spherical cover 42 are rotatably connected to it, meaning the semi-metallic protrusions 43 can roll freely on the surface of the elastic semi-metallic spherical cover 42. As an optional embodiment, the surface of the elastic semi-metallic spherical cover 42 is provided with a spherical cavity, into which the semi-metallic protrusions 43 are embedded and can rotate freely. The depth of the spherical cavity is less than the radius of the semi-metallic protrusions 43, ensuring that a portion of the semi-metallic protrusions 43 protrudes from the surface of the elastic semi-metallic spherical cover 42. The spherical cavity is coated with a lubricating material, such as graphite or molybdenum disulfide, to reduce friction.

[0091] Specifically, the aforementioned rotating connection structure enables the semi-metallic convex sphere 43 to form a rolling friction structure as the wood-carrying cart 5 moves past: when the wood comes into contact with the semi-metallic convex sphere 43, the semi-metallic convex sphere 43 rolls, transforming sliding friction into rolling friction, significantly reducing the frictional resistance between the wood and the sphere cover, and avoiding damage to the surface of the wood. Simultaneously, the rotating semi-metallic convex sphere 43 continuously changes the orientation of its reflective surface during rolling, forming a dynamic microwave-assisted reflection structure, causing the microwave reflection direction to continuously change, further improving the uniformity of the microwave field strength.

[0092] Furthermore, the spherical curvature of the multiple semi-metallic convex spheres 43 on the elastic semi-metallic spherical cover 42 is different, and the spherical curvature of the semi-metallic convex spheres 43 gradually increases from the middle to both ends of the connecting beam 41. Specifically, the spherical radius of the semi-metallic convex spheres 43 in the middle of the connecting beam 41 is 10mm to 15mm, and the spherical radius of the semi-metallic convex spheres 43 at both ends of the connecting beam 41 is 5mm to 8mm, with a smaller spherical curvature in the middle and a larger spherical curvature at both ends.

[0093] Specifically, the semi-metallic convex spheres 43 with different curvatures focus microwaves to varying degrees—the convex spheres with smaller curvatures reflect microwaves more diffusely, while the convex spheres with larger curvatures reflect microwaves more focusedly. Therefore, this structure with gradually varying spherical curvature creates a reflective structure that gradually increases the focusing degree of the microwaves emitted by the magnetron 6, enabling differentiated microwave focusing based on the heating needs of different parts of the wood: the larger diameter section in the middle of the wood, requiring more microwave energy penetration, corresponds to the smaller curvature, more diffusely reflected convex spheres, allowing microwave energy to more evenly cover a large area; the smaller diameter sections at both ends of the wood, which are relatively easy to heat, correspond to the larger curvature, more focused convex spheres, allowing microwave energy to more concentratedly irradiate specific areas. This structure further optimizes the heating effect.

[0094] Equipment structure with microwave stirrer:

[0095] Specifically, based on the above basic equipment structure, a microwave stirrer is provided on the top inner wall of the shielded box 1.

[0096] Specifically, the microwave stirrer is used to reflect and disperse the microwaves emitted by the magnetron 6 within the processing chamber to eliminate microwave standing waves. The microwave stirrer includes a motor and rotating blades. The motor is fixedly mounted on the top outer wall of the shielded box 1, and its output shaft extends into the processing chamber. The rotating blades are fixedly mounted at the end of the output shaft. The rotating blades are made of metal and are fan-shaped or "S"-shaped, with a rotation diameter of 200mm to 500mm.

[0097] Specifically, during operation, the motor drives the rotating blades to rotate at a speed of 10 r / min to 60 r / min, continuously changing the microwave reflection path to make the microwave field strength distribution within the processing chamber more uniform, avoiding localized overheating or underheating. The microwave stirrer is particularly suitable for processing large logs, effectively compensating for the uneven microwave field strength distribution caused by the irregular shape of the logs.

[0098] Equipment structure with microwave reflector:

[0099] Furthermore, based on the above basic equipment structure, a microwave reflector is also provided on the side wall of the shielding box 1.

[0100] Specifically, a microwave reflector is located between two adjacent magnetrons 6, and the reflective surface of the microwave reflector is a concave arc shape, used to focus the microwaves emitted by the magnetrons 6 towards the central area of ​​the processing chamber. The microwave reflector is made of a metal material (such as copper, aluminum, or stainless steel), and its arc surface curvature radius is 200mm to 500mm. The reflective surface is polished, and the surface roughness Ra≤0.8μm to improve microwave reflection efficiency.

[0101] Specifically, the microwave reflector reduces microwave energy loss at the corners of the chamber, directing more microwave energy to the area where the infected wood is located, thus improving energy utilization efficiency. Simultaneously, the curved reflector surface converges parallel microwave beams, increasing microwave energy density in the central area of ​​the processing chamber, which is beneficial for deep heating of large infected wood.

[0102] Specific implementation methods of the processing method:

[0103] Specifically, the present invention also provides a treatment method using any of the above-mentioned wood pest control and disinfection equipment, comprising the following steps:

[0104] S1: Obtain information on the wood type and weight of the infected timber to be treated in a single treatment. .

[0105] Specifically, the timber types include logs and timber squares. Logs refer to whole, unsawed logs, usually with bark, and with a round or near-round cross-section; timber squares refer to sawn boards or square timbers with a rectangular or square cross-section. Operators can determine the timber type by visual observation or measurement of the cross-sectional shape. Single processing weight. The weight is obtained by weighing on an electronic scale or weighbridge, with the unit being kilograms (kg) and the weighing accuracy being ±0.5kg.

[0106] S2: Based on the wood type information and the weight of a single processing step. Determine the target energy coefficient Value range.

[0107] Specifically, the energy coefficient K is calculated according to the following formula:

[0108]

[0109] in, The microwave processing time is expressed in minutes (min). This refers to microwave processing power, measured in kilowatts (kW). The weight of infected wood treated in a single session is expressed in grams (g). The value represents the temperature change of the infected wood before and after treatment, expressed in degrees Celsius (°C).

[0110] Specifically, the energy coefficient The physical meaning of this energy coefficient is a comprehensive representation of the microwave energy and processing time required to raise the temperature of a unit mass of infected wood. This energy coefficient organically integrates four variables—processing time, microwave power, infected wood weight, and temperature rise—into a comprehensive index, which can more comprehensively and accurately reflect the actual effect of microwave treatment.

[0111] Specifically, the target energy coefficient of the log-type infected wood The value range is 2.700. ~2.898 When the energy coefficient of the log-type infected wood reaches the lower limit of this range, 2.700... At this time, a 100% mortality rate can be guaranteed for both pine wilt nematode and pine sawyer beetle; the upper limit is 2.898. This corresponds to the energy coefficient value of 150kg logs under 16-minute processing conditions. Exceeding this upper limit may lead to over-processing, increasing energy consumption and potentially having an adverse effect on the wood material.

[0112] Specifically, the target energy coefficient K value of the aforementioned timber-shaped infected wood is in the range of 1.440. ~1.800 When the energy coefficient of the timber-type infected wood reaches the lower limit of this range, 1.440... At that time, the mortality rate of pine wilt nematode could reach 100%, but the mortality rate of pine sawyer beetle was only 75.4%, which did not meet the requirement of 100% eradication; when the energy coefficient reached 1.800 At this time, the mortality rate of both pine wood nematode and pine sawyer beetle can reach 100%. Therefore, in practical applications, it is preferable to use the upper limit of the target energy coefficient range as the control target to ensure that both pests are completely eradicated.

[0113] Furthermore, for log-type infected timber, when the weight of a single treatment... At a weight of 100kg, the target energy coefficient The preferred value is 2.700. When processing weight in a single batch At 150kg, the target energy coefficient The preferred value is 2.787. For timber-type infected timber, when the weight of a single treatment is... At a weight of 100kg, the target energy coefficient The preferred value is 1.800 When processing weight in a single batch At a weight of 200kg, the target energy coefficient The preferred value is 1.612 .

[0114] S3: Place the infected wood into the microwave processing chamber and start the microwave generator at a high power. Microwave radiation treatment was applied to the infected wood for a period of time of [time missing]. .

[0115] Specifically, the operator places the infected wood on the support surface of the wood-carrying cart 5, pushes the cart 5 along the movable track 4 to the predetermined position, and then drives the movable track 4 along the bottom track 3 via a drive motor to move it into the processing chamber. After closing the chamber door 2, the magnetron 6 (i.e., the microwave generator) is activated to emit microwaves. Microwave processing power... The setting is 24 kW·h. The frequency of the microwave is 2.45 GHz, which is a common frequency band for industrial microwave applications and has the advantages of high heating efficiency and mature and reliable equipment.

[0116] Specifically, during the treatment process, the temperature of the infected wood was gradually increased from room temperature. Pine wood nematodes and pine sawyer beetles were gradually inactivated under the combined effects of the microwave's thermal and biological effects. For log-type infected wood, because the bark has a negative effect on microwave conduction and the log diameter is relatively large, it takes a long time for heat to be conducted from the surface to the interior; therefore, a higher energy coefficient is required to achieve complete eradication. For square-type infected wood, due to its regular shape, compact placement, and easy heat accumulation, a lower energy coefficient is required.

[0117] S4: Detect the temperature change before and after treatment of infected wood. And calculate the current energy coefficient in real time. .

[0118] Specifically, during the processing, the temperature of the infected wood is monitored in real time using temperature sensors. These temperature sensors can be either infrared or thermocouple sensors. The infrared temperature sensor is installed on the top inner wall of the shielded box 1 for non-contact measurement of the surface temperature of the infected wood; the thermocouple temperature sensor is inserted into the infected wood to measure the internal temperature. Preferably, both infrared and thermocouple temperature sensors are used simultaneously to obtain more accurate and comprehensive temperature data. The temperature sensor's detection frequency is 1 to 10 times per second.

[0119] Specifically, the initial temperature of the infected wood before treatment was measured at room temperature, and the real-time temperature during the treatment process was continuously monitored using a temperature sensor. Temperature change values... =Real-time temperature - Initial temperature. Processing power. Given known settings, processing time Timing starts from the moment the microwave is started, and the weight processed in a single cycle is recorded. The weighing value is known.

[0120] Specifically, the control system follows the formula Real-time calculation of current energy coefficient The control system includes a PLC controller or an industrial computer, which is electrically connected to a temperature sensor, a timer, and a power controller to collect temperature data, timing data, and power data and perform real-time calculations.

[0121] S5: When the current energy coefficient Achieve the target energy coefficient determined in step S2 When the value is within the specified range, microwave radiation treatment should be stopped.

[0122] Specifically, the control system will calculate the current energy coefficient in real time. Compare the current energy coefficient K with the preset target energy coefficient value. When the current energy coefficient K reaches the target energy coefficient value (i.e., ... ≥ When the target is reached, the control system issues a stop command, the magnetron 6 stops emitting microwaves, and the processing ends.

[0123] Specifically, by using the achievement of a target energy coefficient as the termination condition for treatment, rather than relying on a fixed treatment time or temperature value, this method can adaptively address differences in moisture content, initial temperature, and wood density among different batches of infected wood, ensuring the stability and consistency of the treatment effect. For example, for infected wood of the same type and weight, if its initial moisture content is high, the temperature rise rate is slower, and the time required to reach the target energy coefficient is longer; conversely, if the initial moisture content is low, the temperature rise rate is faster, and the required time is shorter. This invention, through real-time feedback control of the energy coefficient, can automatically adapt to these differences, avoiding over-treatment or under-treatment.

[0124] Furthermore, after processing, the movable track 4 moves the timber cart 5 out of the processing chamber, and the box door 2 is opened to remove the treated infected timber. The treated infected timber is then sampled and tested to determine the mortality rates of pine wilt nematodes and pine sawyer beetles. When both the pine wilt nematode mortality rate and the pine sawyer beetle mortality rate reach 100%, the infected timber is confirmed to have met the harmless treatment standards. After passing the tests, the infected timber can be labeled and shipped out of the factory, entering the market in its original log form.

[0125] (II) Specific processing parameters under different working conditions

[0126] Specifically, when the wood type is logs and the weight per single processing session is... When the weight is 100 kg, the diameter of the wood is 120-180 mm, and the relative humidity of the wood is 20%-40%, the microwave processing power is set as follows: =24kW·h, target energy coefficient The value is 2.700 After starting the microwave generator, the temperature change is monitored in real time and the energy coefficient is calculated. When the processing time reaches 12 minutes and the temperature change Δt reaches 64℃, the current energy coefficient K reaches 2.700. Microwave radiation treatment was stopped. Testing showed that the mortality rates of pine wilt nematodes and pine sawyer beetles in the treated wood both reached 100%.

[0127] Specifically, when the wood type is logs and the weight per single processing session is... When the weight is 150 kg, the diameter of the wood is 120-180 mm, and the relative humidity of the wood is 20%-40%, the microwave processing power is set accordingly. =24kW·h, target energy coefficient The value is 2.787 After starting the microwave generator, temperature changes are monitored in real time and the energy coefficient is calculated. When the processing time reaches 18 minutes, the temperature change... At 62℃, the current energy coefficient Reached 2.787 Microwave radiation treatment was stopped. Testing showed that the mortality rates of pine wilt nematodes and pine sawyer beetles in the treated wood both reached 100%.

[0128] Specifically, when the type of wood is square timber and the weight per single processing step is... When the weight is 100 kg, the wood thickness is 80–120 mm, and the relative humidity of the wood is 20%–40%, set the microwave processing power. =24kW·h, target energy coefficient The value is 1.800 After starting the microwave generator, temperature changes are monitored in real time and the energy coefficient is calculated. When the processing time reaches 8 minutes, the temperature change of the infected wood is measured. At 64℃, the current energy coefficient achieve Microwave radiation treatment was stopped. Testing showed that the mortality rates of pine wilt nematodes and pine sawyer beetles in the treated timber both reached 100%.

[0129] Specifically, when the type of wood is square timber and the weight per single processing step is... When the weight is 200 kg, the wood thickness is 80–120 mm, and the relative humidity of the wood is 20%–40%, the microwave processing power is set as follows: =24kW·h, target energy coefficient The value is 1.612 After starting the microwave generator, the temperature change is monitored in real time and the energy coefficient is calculated. When the processing time reaches 15 minutes, the temperature change of the infected wood is monitored. At 67℃, the current energy coefficient Reached 1.612 Microwave radiation treatment was stopped. Testing showed that the mortality rates of pine wilt nematodes and pine sawyer beetles in the treated timber both reached 100%.

[0130] III. Experimental Verification and Data Analysis

[0131] Specifically, in order to verify the technical effect of the treatment method of the present invention, the applicant conducted a systematic experimental study on the effect of microwave treatment on infected wood under different conditions.

[0132] (I) Test results of log-type infected timber

[0133] Specifically, for log-type infected timber (timber diameter 120–180 mm, relative humidity 20%–40%), the test results under different treatment conditions are shown in Table 1:

[0134] Table 1. Treatment effects of different treatment conditions on log-type infected wood.

[0135] T1 100 5 45 72.4 66.4 1.800 T2 100 8 50 84.2 75.7 2.304 T3 100 10 58 94.5 88.7 2.483 T4 100 12 64 100 100 2.700 T5 150 12 42 77.5 72.4 2.743 T6 150 14 47 95.4 85.4 2.860 T7 150 16 53 100 94.7 2.898 T8 150 18 62 100 100 2.787

[0136] Furthermore, the experimental results in Table 1 show that when the log-type infected wood reaches a 100% mortality rate (both pine wood nematode and pine sawyer beetle die), the energy coefficient... The range is 2.700 to 2.898. When the energy coefficient is below 2.700, it cannot be guaranteed that both pests will achieve 100% mortality. For example, the energy coefficient for treatment T3 is 2.483. At that time, the mortality rate of pine wilt nematode was 94.5%, and the mortality rate of pine sawyer beetle was only 88.7%, neither of which met the requirements for complete eradication.

[0137] Furthermore, Table 1 also shows that the energy coefficient required to completely eradicate infected logs increases slightly with the increase of the weight of a single treatment: the energy coefficient for complete eradication is 2.700 for 100kg of logs. (T4 treatment) The energy coefficient for complete eradication of 150kg of logs is 2.787. (T8 treatment). This indicates that the difficulty of treating log-type infected wood increases slightly with the increase of the weight of a single treatment, and appropriate compensation needs to be made in terms of energy coefficient.

[0138] Test results of timber-type infected wood

[0139] Specifically, for the diseased timber squares (wood thickness 80–120 mm, relative humidity 20%–40%), the test results under different treatment conditions are shown in Table 2:

[0140] Table 2. Treatment effects of infected timber squares under different treatment conditions.

[0141] T9 100 5 50 84.5 75.4 1.440 T10 100 6 54 92.3 82.4 1.600 T11 100 7 58 100 94.1 1.738 T12 100 8 64 100 100 1.800 T13 200 8 48 83.7 74.7 1.200 T14 200 10 52 91.4 79.5 1.385 T15 200 12 58 100 90.8 1.490 T16 200 15 67 100 100 1.612

[0142] Furthermore, the experimental results in Table 2 show that when the mortality rate of the infected timber reaches 100%, the energy coefficient... The range is 1.440 to 1.800. Specifically, the energy coefficient for complete extermination of 100kg of timber is 1.800. (For T12 treatment), the energy coefficient for achieving complete extermination with 200 kg of timber is 1.612. (Process T16).

[0143] Furthermore, comparing the experimental results in Tables 1 and 2 reveals that the energy coefficient required for the treatment of infected timber squares is generally lower than that for infected timber logs. Under the same treatment weight (100 kg), the energy coefficient for achieving complete eradication of infected timber logs is 2.700. The timber-type diseased timber was only 1,800. The former is 1.5 times that of the latter. This may be because the bark of log-type infected wood has a negative effect on microwave conduction, and the larger diameter of log-type infected wood makes the efficiency of heat conduction from the surface of the wood to the interior lower, thus requiring a higher energy coefficient to achieve complete eradication.

[0144] Furthermore, Table 2 also shows that the energy coefficient required to completely eradicate infected timber decreases with increasing weight of the timber in a single treatment: 1.800 for 100kg timber. (T12 treatment), 200kg of timber is 1.612 (T16 treatment). This is likely because as the treatment weight increases, the timber is placed more compactly, making it easier for heat to accumulate and resulting in higher energy utilization efficiency. In terms of treatment costs, the overall treatment cost of timber-type infected timber is lower than that of log-type infected timber.

[0145] Energy cost analysis:

[0146] Specifically, taking into account the energy consumption cost of harmless treatment of infected wood, the treatment cost of infected wood of different types and weights was calculated based on the experimental data in Tables 1 and 2 and the current industrial electricity price (calculated at RMB 1 / kWh).

[0147] Specifically, when treating 150 kg of infected logs at a time, with a processing time of 18 minutes and a power consumption of 24 kW·h, the electricity consumption per treatment is 7.2 kWh, and the cost is approximately 7.2 yuan, which translates to a processing cost of 48 to 60 yuan per ton.

[0148] Specifically, when processing 200 kg of infected timber at a time, with a processing time of 15 minutes and a power consumption of 24 kW·h, the electricity consumption per processing session is 6.0 kWh, and the cost is approximately 6.0 yuan, which translates to a processing cost of 30 to 45 yuan per ton.

[0149] Furthermore, the microwave treatment method of this invention has significantly lower processing costs than existing methods such as incineration (several hundred yuan per ton) and pulverization, demonstrating good economic benefits and promising prospects for widespread application. Simultaneously, the treated infected wood can enter the market in its original log form, further enhancing its economic value and making the entire treatment process economically sustainable.

[0150] Specifically, the working principle of the wood disease prevention and control equipment of the present invention is as follows:

[0151] The infected timber to be treated is first placed on the bearing surface of the timber carrier 5. The timber carrier 5 carries the infected timber and moves along the movable track 4. During the movement, the infected timber passes sequentially through multiple rows of elastic semi-metallic spherical covers 42 arranged on the movable track 4. Since the top of the elastic semi-metallic spherical covers 42 is higher than the bearing surface, the infected timber will come into contact with the elastic semi-metallic spherical covers 42 during the movement. The elastic semi-metallic spherical covers 42 undergo elastic deformation and form auxiliary support for the middle of the infected timber. As the height of the multiple elastic semi-metallic spherical covers 42 gradually decreases from the middle to both ends of the connecting beam 41, the infected timber at different positions will come into contact with spherical covers of different heights and positions, realizing graded bearing of the timber at different locations and preventing timber deformation.

[0152] Once the infected wood has fully entered the predetermined position of the wood-carrying cart 5, the movable track 4, driven by the drive motor, moves the wood-carrying cart 5 along the bottom track 3 into the processing chamber of the shielded box 1. After the box door 2 is closed, the magnetron 6 is activated according to the power and time parameters set in the aforementioned processing method.

[0153] Magnetron 6 emits microwaves at a frequency of 2.45 GHz from multiple side walls of shielded box 1 into the processing chamber. The microwaves emitted by magnetron 6, located below the bearing surface, irradiate the semi-metallic surface of the elastic semi-metallic dome 42 and are reflected towards the bottom and sides of the wood, allowing the microwaves to reach the bottom region of the wood. Simultaneously, the semi-metallic convex spheres 43 on the surface of the elastic semi-metallic dome 42 further expand and reflect the microwaves in multiple directions, and the rotating semi-metallic convex spheres 43 continuously change the reflection direction. A microwave stirrer at the top of shielded box 1 rotates at a speed of 10 r / min to 60 r / min, reflecting and dispersing the microwaves within the processing chamber to eliminate microwave standing waves.

[0154] Under the aforementioned multiple reflections, expansions, and convergences, microwaves form a uniformly distributed microwave field within the treatment chamber, providing all-round and uniform microwave radiation heating to the infected wood. The thermal effect of microwaves causes intense friction between moisture and organic molecules inside the infected wood, generating heat. The biological effect of microwaves damages the cellular structure and physiological functions of organisms. Together, these two factors cause the pine wood nematodes and pine sawyer beetles inside the infected wood to become inactive and die within a short period of time.

[0155] During the treatment process, temperature sensors monitor the temperature changes of the infected wood in real time, and the control system calculates the temperature according to the preset energy coefficient target value using the formula. The system calculates the current energy coefficient in real time and automatically stops microwave radiation treatment when the target value is reached, achieving precise control.

[0156] After processing, the drive motor drives the movable track 4 to move the timber cart 5 out of the processing chamber, and the box door 2 is opened to take out the processed infected timber. After testing shows that the mortality rate of pine wood nematode and pine sawyer beetle has reached 100%, the infected timber can be labeled and shipped out of the factory, entering the market in the form of raw timber.

[0157] The processing method (1) of this invention proposes an energy coefficient for the first time. As the core control parameter for microwave-treated wood, the four variables of treatment time, microwave power, wood weight, and temperature rise are organically integrated into a comprehensive index, which realizes precise quantitative control of the microwave treatment process.

[0158] (2) For the first time, differentiated target energy coefficient ranges were set according to timber type (log type and timber square type) (log type: 2.700~2.898). Timber square type: 1.440~1.800 This technology enables differentiated and precise treatment of different types of infected wood, solving the problems of energy waste and unstable treatment effects caused by the existing "one-size-fits-all" treatment mode.

[0159] (3) By detecting temperature changes in real time and calculating the current energy coefficient, the treatment is terminated when the energy coefficient reaches the standard, rather than relying on a fixed treatment time or temperature. This can adaptively cope with the differences in moisture content, initial temperature, etc. of different batches of infected wood, ensuring the stability and consistency of the treatment effect.

[0160] (4) The treatment effect is reliable, and the mortality rate of pine wood nematode and pine sawyer beetle can reach 100%. The cost of treating 150kg of log-type infected wood at one time is 48-60 yuan / t, and the cost of treating 200kg of square-type infected wood at one time is only 30-45 yuan / t. The treatment cost is significantly lower than existing methods such as incineration and crushing.

[0161] (5) After treatment, the infected wood can enter the market in its original form, breaking the single utilization method of infected wood that can only be crushed and rotary cut for papermaking. This transforms infected wood from "waste" into "usable material", greatly enriching the safe and efficient utilization of infected wood, increasing the economic value of infected wood, and solving the fundamental problem of infected wood loss from an economic perspective.

[0162] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
