Description

Technical Field

[0001] The present invention relates to the technical field of invasive plant eradication, and particularly to an integrated mobile physical eradication device for alien invasive plants. Background Art

[0002] Alien invasive plants refer to plants that are not native and evolved in a specific regional ecosystem but are later spread from other regions through different channels. If these plants can grow and reproduce under natural conditions, they constitute the invasion of alien plants. Alien invasive plants reproduce by seeds and rhizomes, with extremely strong reproductive ability, fast spreading speed, rapid growth, and strong ecological adaptability, and can grow from mountain slopes and woodlands to swamp areas.

[0003] Currently, the eradication of alien invasive plants usually adopts cutting or using chemical drugs. Although cutting can quickly cut down the growing invasive plants, if the rhizomes and seeds are not disposed of in time, it is very easy for them to take root and germinate again and for the seeds to reproduce, resulting in a decline in the eradication effect. And using chemical drugs for killing will pollute the land, reduce the fertility of the land, and cause harm to the growth of native plants. Summary of the Invention

[0020] As a preferred solution, furthermore, the gasification assembly 11 includes a refractory layer 1101, an inner top plate 1102, a refractory arch 1103, a discharge pipe support 1104, a poking door 1105, a gasification air inlet valve 1106, a grate support plate 1107, and a rotating grate 1108. The refractory layer 1101 is arranged on the left inner wall of the square inner housing 18. The inner top plate 1102 is arranged on the top of the refractory layer 1101. The refractory arch 1103 is arranged on the lower surface. A gasification space is constructed by the refractory layer 1101 and the refractory arch 1103. The discharge pipe support 1104 is arranged on the left side of the inner top plate 1102. The poking door 1105 and the gasification air inlet valve 1106 are arranged on the top of the left side wall of the square inner housing 18 from top to bottom. The grate support plate 1107 is welded to the middle and lower part of the square inner housing 18. Two rotating grates 1108 are arranged on the front of the square outer housing 16. The rotating grates 1108 are supported by the grate support plate 1107. The refractory layer 1101 and the refractory arch 1103 form a high-temperature sealed space. The inner top plate 1102 and the grate support plate 1107 respectively support the top and the middle and lower parts to form a physical space for material gasification.

[0021] As an optimal solution, furthermore, the rotary grate 1108 further includes a sleeve 1109, a sleeve flange 1110, a sealing flange 1111, a stainless steel 310S short rod 1112, an air vent 1113 and a handle 1114. Two sleeves 1109 are welded to the outer wall of the support plate 1107 relatively left and right, pass through the square inner housing 18, the heat insulation layer 17, and the square outer housing 16, and the rotary grate 1108 passes through the inner cavity of the sleeve 1109. The sleeve flange 1110 is welded to the front end of the sleeve 1109. Both ends of the rotary grate 1108 pass through the sleeve 1109. The sealing flange 1111 is movably arranged on the outer wall of the rotary grate 1108, and the sealing flange 1111 and the sleeve flange 1110 are locked by bolts. A packing rope is used as the sealing material between the sealing flange 1111 and the sleeve flange 1110 to achieve the sealing when the rotary grate 1108 rotates. The part of the rotary grate 1108 inside the furnace is welded with stainless steel 310S short rods 1112 as grate bars to solve the problem of high-temperature melting. The rotary grate 1108 is made of hollow stainless steel 316L material, which is high-temperature resistant and corrosion-resistant. An air vent 1113 and a handle 1114 are arranged at the manual end of the rotary grate 1108. The handle 1114 is screwed onto the manual end of the rotary grate 1108 for shaking and flipping the rotary grate 1108. The air vent 1113 is communicated with the inner cavity of the rotary grate 1108, and the other end of the rotary grate 1108 is communicated with the atmosphere. When the rotary grate 1108 receives the high temperature of the firebed in the gasification device 11, the outside cold air enters through the non-blocked end of the rotary grate 1108 by the force of cold and hot convection. After cooling the rotary grate 1108, the hot air is discharged from the air outlet 1113.

[0022] The rotary grate 1108 is manually flipped through the handle 1114, which can stir the materials and promote uniform gasification. The hollow structure utilizes the principle of cold and hot convection. The outside cold air enters from one end of the grate, and the hot air is discharged from the air vent 1113 after cooling the grate, preventing the grate from overheating. After the cut invasive plants are dried by the drying component 15, they are pushed into the gasification component 11 through the gas check valve plate 1503. The check valve plate 1503 automatically closes to isolate the gas from flowing back. Initially, dry straw is added through the fire door 1105 and ignited to form a firebed, and then the dried materials are continuously input. Outside air is introduced through the gasification air intake valve 1106, and natural draft is formed by the height difference gravity of the waste gas discharge pipe 3 to make the air enter the gasification space. The materials are thermally decomposed under oxygen-deficient or oxygen-limited conditions to generate combustible gases (such as CO, H2, CH4, etc.), and the residual ash falls into the ash box 1201 of the lower ash chamber 12 for temporary storage. The generated gas descends under the action of the gas flow gravity, enters the ash chamber through the gaps of the rotary grate, and is transported to the oxidation component 14 for combustion through the throat pipe 1203.

[0023] The chimney effect relying on the exhaust gas pipe 3 forms a height difference gravitational force, eliminating the need for additional power equipment and achieving the natural circulation of air inhalation and gas discharge, which is applicable to the field without electricity; the heat generated during the gasification process is transferred to the lower hot air component 13, heating the air and then used for drying the materials of the drying component 15, forming a self-heating cycle and reducing energy consumption.

[0029] The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, and the specific work is as follows.

[0030] Step 1: Use the manual lifting device 4 of the exhaust gas pipe to lay down the exhaust gas pipe 3 on the exhaust pipe support 1104, which facilitates the tractor to tow this device to the roadside, field edge or treatment point. Then, use the manual lifting device 4 of the exhaust gas pipe to raise the exhaust gas pipe 3 and lock it. Ignite the liquefied gas torch. Where conditions permit, a diesel burner can also be inserted through the liquefied gas torch interface 1411 to heat the cylindrical inner shell 1401. At the same time, heat the hot air assembly 13, the secondary heating pipe 1304 and the hot air header 1305. Subsequently, start the blower, blow air into the hot air assembly 13 through the blower interface 1303, heat it through the secondary heating pipe 1304 and then enter the hot air header 1305. Then, enter the drying assembly 15 through the air inlet hole 1502 of the drying assembly 15 to dry the material. The cut and collected alien invasive plants are loaded into the drying cylinder 1501 through the first feed door 1504 and dried using the hot air generated by the hot air assembly 13. Subsequently, prepare a small amount of dry straw, load it into the gasification assembly 11 through the fire door 1105 and ignite it. After igniting the entire firebed, close the fire door 1105 and appropriately open the gasification air inlet valve 1106 on the fire door 1105. Then, use the furnace rake to push the alien invasive plants in the drying cylinder 1501 into the gasification assembly 11 through the gas check valve plate 1503 for gasification treatment. Subsequently, the gas check valve plate 1503 automatically closes under its own gravity to prevent the gas in the gasification assembly 11 from overflowing through the drying assembly 15. The gasification air enters the gasification assembly 11 under the differential elevation gravitational force of the exhaust gas pipe 3 through the gasification air inlet valve 1106, and the material is gasified using static gasification technology to generate gas. The gas also descends under the differential elevation gravitational force of the exhaust gas pipe 3, passes through the rotary grate 1108 and enters the ash chamber 12, and then enters the oxidation assembly 14 through the throat pipe 1203. The ash residue generated after the material is gasified directly falls into the ash box 1201 for temporary storage. After the gas enters the oxidation assembly 14, it also ascends under the differential elevation gravitational force of the exhaust gas pipe 3 and is ignited by the liquefied gas torch. The primary air required at the bottom of the oxidation assembly 14 also enters the primary air header 1403 through the differential elevation gravitational force of the exhaust gas pipe 3, and after being heated by controlling the flow rate through the primary flow control valve 1406, it is sprayed out through the primary air nozzle 1404 to fully mix and burn with the gas. The secondary air required in the middle and lower parts of the oxidation assembly 14 also enters the secondary air header 1407 through the differential elevation gravitational force of the exhaust gas pipe 3, and after being heated by controlling the flow rate through the secondary air flow control valve 1410, it is sprayed out through the secondary air nozzles 1408 evenly distributed on the secondary air header 1407, and once again fully mixes and burns with the gas.

[0031] In Step 2, the heat generated when the gas produced by the gasification assembly 11 descends through the ash chamber 12 and the heat generated by the ash residue falling into the ash bin 1201 heat the air in the hot air assembly 13. At the same time, the high-temperature flue gas generated by the combustion of the gas in the oxidation assembly 14 also heats the air in the secondary heating pipe 1304. The generated hot air rises and enters the hot air header 1305 to provide heat for the drying assembly 15. When the gas in the oxidation assembly 14 can self-ignite, the liquefied gas torch can be turned off to realize self-heating and drying of the foreign invasive plants. The materials in the drying assembly 15 are timely pushed into the gasification assembly 11 along with the gasification progress, and new materials are loaded to continue the drying process. After the gas burns fully in the oxidation assembly 14, a small amount of waste gas is generated. It also rises by the height difference gravity of the waste gas discharge pipe 3, bypasses the drying assembly 15 to release heat and then continues to rise, and directly enters the square dust removal box 21 of the double-alkali purification mechanism 2 through the waste gas outlet 1414. It is filtered and dust-removed by activated carbon or volcanic pumice, and after adsorption and purification, it is dust-removed again by the corner force. Then it enters the cylindrical spray purification box 22 for bath purification treatment with alkali liquor, and then rises to enter the waste gas discharge pipe 3 for up-to-standard discharge.

[0032] In Step 3, when the waste gas is bathed with alkali liquor, 3.5 kg of calcium oxide is added to the calcium hydroxide mixing tank 503, and then clear water is added to reach the highest water level. The siphon automatically pours the calcium oxide mixed liquid into the first water tank 501. 1.6 kg of sodium oxide is added to the sodium hydroxide mixing tank 504, and then clear water is added to reach the highest water level. The siphon automatically pours the sodium oxide mixed liquid into the second water tank 502. The sodium oxide liquid in the second water tank 502 is pumped into the cylindrical spray purification box 22 by the water pump 508 and sprayed out through the spray nozzles 223 to bathe the waste gas for desulfurization, denitrification, and dust removal and purification treatment. The liquid in the cylindrical spray purification box 22 falls to the bottom of the square dust removal box 21 and is mixed with the calcium oxide liquid in the first water tank 501 through the water outlet interface 217 to be regenerated into sodium hydroxide solution, which enters the second water tank 502 through the connecting pipe for recycling. When the furnace is stopped, the valve on the pipe of the return spray liquid outlet 510 on the first water tank 501 is opened to spray the waste water into the ash chamber 12 to extinguish the fire and reduce dust. Then the slag discharge door 1202 is opened to clean the ash residue, which is directly returned to the field for treatment.
