Description

Technical Field

[0001] The invention relates to the technical field of white phosphorus production, in particular to a white phosphorus production device based on mud phosphorus recovery. Background Art

[0002] Mud phosphorus is a byproduct of phosphorus and impurities mixed together during the production of yellow phosphorus. Its main components are phosphorus and solid impurities. Phosphorus easily condenses on solid impurities, making it difficult to separate phosphorus from other impurities, making it difficult to recover the phosphorus in the mud phosphorus. However, the mud phosphorus contains certain highly toxic compounds, which will cause serious pollution to the environment if not treated.

[0003] The current method for recycling sludge phosphorus mainly utilizes a closed steel rotating cylinder, uses exhaust gas to heat the outside of the cylinder, and the white phosphorus vaporizes after being heated, and the vaporized white phosphorus is collected.

[0004] However, the sludge phosphorus is a viscous muddy solid, and its distribution in the treatment barrel is uneven. Some parts will agglomerate together, causing the sludge phosphorus in the treatment barrel to be irregularly distributed, with some areas having more sludge phosphorus and some areas having less sludge phosphorus. However, the existing recovery equipment has the same temperature in each area during heating, and cannot automatically adjust the heating temperature according to the amount of sludge phosphorus in different areas. Summary of the invention

[0005] The object of the present invention is to provide a white phosphorus production device based on sludge phosphorus recovery to solve the problems raised in the prior art.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: The present invention provides a technical solution of a white phosphorus production device based on mud phosphorus recovery, the white phosphorus production device includes a casing, a combustion chamber, a processing chamber, a stirring mechanism and an adjusting mechanism, the combustion chamber is tightly connected to the casing, the processing chamber is tightly connected to the combustion chamber, the processing chamber is located in the combustion chamber, the stirring mechanism is rotatably connected to the processing chamber, the adjusting mechanism is tightly connected to the stirring mechanism, and the adjusting mechanism is used to adjust the air intake of the combustion chamber.

[0007] The invention uses tail gas generated by producing white phosphorus as fuel to heat mud phosphorus, so that phosphorus in the mud phosphorus is heated and vaporized for recovery. Firstly, mud phosphorus to be recovered is placed in a processing chamber, and tail gas is introduced into a combustion chamber for ignition, so that heat is transferred to the mud phosphorus in the processing chamber, so that white phosphorus in the mud phosphorus is heated and vaporized. In order to ensure that the mud phosphorus in the processing chamber is heated evenly, a stirring mechanism is used for stirring. An adjusting mechanism is used for judging the distribution of the mud phosphorus in the processing chamber, and can specifically adjust the air intake at the corresponding position according to the distribution amount of the mud phosphorus at different positions in the processing chamber, so that the temperature distribution in the combustion chamber is matched with the distribution of the mud phosphorus in the processing chamber, thereby improving the heating efficiency of the mud phosphorus.

[0008] Furthermore, the stirring mechanism includes a driving motor, a main shaft and stirring blades. The driving motor is firmly connected to the casing, the output end of the driving motor is transmission-connected to the main shaft, the main shaft is rotationally connected to the processing chamber, the stirring blades are firmly connected to the main shaft, and several groups of stirring blades are arranged on the main shaft.

[0009] The driving motor is the main power source of the stirring mechanism. The driving motor outputs torque, thereby driving the main shaft to rotate in the processing chamber, so that the stirring blades rotate at a low speed in the processing chamber, thereby turning over the mud in the processing chamber, making it heated evenly, thereby improving the heating efficiency.

[0010] Furthermore, a movable groove is provided on the stirring blade, and a force block is slidably connected to the movable groove. The force block is located on the material-facing surface of the stirring blade. A liquid storage cavity is provided in the main shaft, and the movable groove is connected to the liquid storage cavity, and the liquid storage cavity is connected to the adjustment mechanism.

[0011] Hydraulic oil is filled in the movable groove and the liquid storage chamber. When the stirring blade contacts the mud phosphorus in the processing chamber during rotation, the mud phosphorus will exert a reaction force on the force-bearing block, causing the force-bearing block to slide along the movable groove, thereby pressing the hydraulic oil in the movable groove into the liquid storage chamber, and transmitting the pressure to the liquid storage chamber; because the stirring blades are arranged in several groups on the main shaft, and the distribution of the mud phosphorus in the processing chamber is uneven, when a group of stirring blades contacts an area with more mud phosphorus, because the mud phosphorus in this area is heavy, the reaction force on the force-bearing block is greater, the distance the force-bearing block slides along the movable groove is longer, and the pressure transmitted to the liquid storage chamber is greater.

[0012] Furthermore, the regulating mechanism includes a sensing component and an air supply component. The sensing component is tightly connected to the main shaft, and is used to determine the distribution of mud phosphorus in the processing chamber. The air supply component is tightly connected to the casing, and is used to adjust the air intake volume.

[0013] The sensing component can determine the distribution of mud phosphorus in the processing chamber by analyzing the pressure changes in the liquid storage chamber, and then introduce outside air through the air supply component to change the oxygen content in different areas of the combustion chamber. The more mud phosphorus is distributed in an area, the more oxygen will be introduced into the combustion chamber, thereby promoting combustion and increasing the temperature of the corresponding area. It realizes automatic adjustment of the temperature of different areas according to the distribution of mud phosphorus, thereby improving the heating efficiency of the mud phosphorus.

[0014] Furthermore, several sensing components are arranged along the circumference of the main shaft, and the several sensing components include a connecting column, a slider, a movable magnet and a reset spring. The connecting column is tightly connected to the main shaft, an adjusting groove is provided in the connecting column, the adjusting groove is communicated with the liquid storage chamber, the slider is slidably connected to the adjusting groove, one end of the reset spring is tightly connected to the inner wall of the adjusting groove, the other end of the reset spring is tightly connected to the slider, the reset spring is located at one end of the adjusting groove close to the main shaft, the movable magnet is tightly connected to the slider, and the movable magnet is located at one end of the adjusting groove away from the main shaft.

[0015] The connecting column is fixed on the main shaft and serves as the main support of the sensing component. The more mud and phosphorus are distributed in the processing chamber, the greater the reaction force on the force block will be, and the greater the pressure transmitted to the liquid storage chamber will be. Under the action of pressure, the slider will be pushed to move along the adjustment groove away from the main shaft, and the reset spring will be stretched under the force, which will drive the moving magnet to move toward the inner wall of the processing chamber, reducing the relative distance between the moving magnet and the processing chamber. Moreover, the more mud and phosphorus are distributed in the processing chamber, the closer the distance between the moving magnet and the processing chamber will be.

[0016] Furthermore, a protrusion is provided on the casing, and the protrusion passes through the combustion chamber and is close to the outer wall of the processing chamber. An air guide channel and a reciprocating groove are provided in the protrusion. The air supply assembly includes a first movable part and a second movable part. The first movable part is located in the reciprocating groove, and the second movable part is located in the air guide channel. The second movable part is arranged on both sides of the reciprocating groove. The air outlet end of the air guide channel is connected to a gas supply pipeline, and the gas supply pipeline is connected to the combustion chamber. A burner head is provided in the combustion chamber, and the air outlet end of the gas supply pipeline faces the burner head. The position of the burner head corresponds to the stirring blade. A smoke exhaust port is provided on the combustion chamber, and a partition is provided between the burner heads.

[0017] The raised portion on the casing is used to accommodate the air supply component, so that the air supply component is close to the processing chamber, so that the sensing component and the air supply component are linked, the air guide channel and the reciprocating groove in the raised portion form a T-shape, the moving magnet is used to drive the first movable part to move, and the first movable part is used to drive the second movable part to move, and the outside air is transported to the gas pipeline through the air guide channel, thereby introducing the outside air into the combustion chamber to increase the oxygen content in the corresponding area, thereby increasing the combustion temperature at the corresponding position of the combustion head, and the combustion heads are separated by partitions, so that the processing chamber can be heated in zones, and the temperature between each zone can be automatically adjusted according to the mud phosphorus distribution amount detected by the sensing component, so as to realize automatic adjustment of the temperature of different areas according to the distribution of mud phosphorus.

[0018] Furthermore, the first movable part includes a movable magnet and a movable spring, the movable magnet is slidably connected to the reciprocating groove, one end of the movable spring is firmly connected to the movable magnet, and the other end of the movable spring is firmly connected to the wall of the reciprocating groove, and the facing ends of the movable magnet and the movable magnet are opposite poles.

[0019] Because the positions of the air supply component and the sensing component are corresponding, when the sensing component rotates at a fixed speed driven by the main shaft, the moving magnet will continuously approach and move away from the active magnet. According to the principle of opposites attract, when the moving magnet approaches the active magnet, the active magnet will overcome the elastic force of the active spring and move toward the processing chamber along the reciprocating groove to draw air into the air guide channel. When the moving magnet moves away from the active magnet, the attraction between the two becomes smaller. Under the action of the elastic force of the active spring, the active magnet will move to the other side along the reciprocating groove, thereby pressing the inhaled air into the air guide channel. Therefore, when the moving magnet rotates driven by the main shaft, it can drive the active magnet along the reciprocating groove. The groove continuously makes reciprocating motion, thereby continuously sucking in air; and because the more areas in the treatment chamber where mud phosphorus is distributed, the closer the distance between the moving magnet and the treatment chamber is, that is, the closer the distance between the moving magnet and the active magnet is, the greater the magnetic force between the two is, the longer the distance the active magnet moves along the reciprocating groove, the more air is sucked in, and the more oxygen is delivered to the combustion head at the corresponding position, that is, it is realized that according to the distribution of mud phosphorus in the treatment chamber, the air content input into different areas of the combustion chamber is automatically adjusted, so that the temperature of different areas in the combustion chamber is adaptively adjusted according to the distribution of mud phosphorus, and the more areas where mud phosphorus is distributed, the higher the temperature, thereby improving the heating efficiency.

[0020] Furthermore, the second movable part includes a fixing ring, a clamping head, a clamping spring and a connecting seat. The fixing ring and the connecting seat are tightly connected to the inner wall of the air guide channel. The clamping head abuts against the fixing ring. The clamping spring is arranged between the clamping head and the connecting seat. The connecting seat is provided with a flow hole.

[0021] In the initial state, the clamping head is pressed against the surface of the fixed ring under the elastic force of the clamping spring. At this time, the air guide channel is in a closed state. When the first movable part moves along the reciprocating groove toward the side close to the processing chamber, the volume of the connecting part between the reciprocating groove and the air guide channel will increase, thereby generating negative pressure, so that the clamping head on the air inlet side can overcome the elastic force of the clamping spring, and air flows into the air guide channel through the flow holes on the connecting seat. When the first movable part moves toward the side away from the processing chamber, the pressure in the reciprocating groove increases, and the clamping head on the air outlet side overcomes the elastic force of the clamping spring, and air flows into the gas pipeline. Therefore, when the first movable part continuously reciprocates in the reciprocating groove, air will be continuously drawn into and pressed out of the air guide channel, thereby increasing the oxygen content in the combustion chamber at the corresponding position and promoting combustion.

[0022] Furthermore, the stirring blade is fan-shaped, and the cross-sectional area of ​​the regulating groove is one twentieth of the cross-sectional area of ​​the force-bearing block.

[0023] The fan-shaped stirring blade can increase the contact area with the mud, thereby increasing the force on the force block. The cross-sectional area of ​​the adjustment groove is smaller than the cross-sectional area of ​​the force block, which can amplify the moving distance of the force block, thereby increasing the adjustment range of the moving magnet in the adjustment groove.

[0024] Furthermore, a feed port and a discharge port are provided at one end of the processing chamber.

[0025] Mud phosphorus enters the treatment chamber from the feed port, and the white phosphorus that is heated and vaporized is discharged through the discharge port.

[0026] Compared with the prior art, the present invention has the following beneficial effects: The positions of the air supply component and the sensing component are corresponding, so when the sensing component rotates at a fixed speed driven by the main shaft, the moving magnet will continuously approach and move away from the active magnet. According to the principle of opposites attract, when the moving magnet approaches the active magnet, the active magnet will overcome the elastic force of the active spring and move toward the processing chamber along the reciprocating groove to draw air into the air guide channel. When the moving magnet moves away from the active magnet, the attraction between the two becomes smaller, and the active magnet will move to the other side along the reciprocating groove under the elastic force of the active spring, thereby pressing the inhaled air into the air guide channel. Therefore, when the moving magnet rotates driven by the main shaft, it can drive the active magnet along the reciprocating groove. It continuously makes reciprocating motion, thereby continuously sucking in air; and because the more areas in the treatment chamber where mud phosphorus is distributed, the closer the distance between the moving magnet and the treatment chamber is, that is, the closer the distance between the moving magnet and the active magnet is, the greater the magnetic force between the two is, the longer the distance the active magnet moves along the reciprocating groove, the more air is sucked in, and the more oxygen is delivered to the combustion head at the corresponding position, that is, it is realized that according to the distribution of mud phosphorus in the treatment chamber, the air content input into different areas of the combustion chamber is automatically adjusted, so that the temperature of different areas in the combustion chamber is adaptively adjusted according to the distribution of mud phosphorus, and the more areas where mud phosphorus is distributed, the higher the temperature, thereby improving the heating efficiency.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Example: Figure 1-Figure 9 As shown, the present invention provides a technical solution of a white phosphorus production device based on mud phosphorus recovery, the white phosphorus production device includes a casing 1, a combustion chamber 2, a processing chamber 3, a stirring mechanism 4 and an adjusting mechanism 5, the combustion chamber 2 is tightly connected to the casing 1, the processing chamber 3 is tightly connected to the combustion chamber 2, the processing chamber 3 is located in the combustion chamber 2, the stirring mechanism 4 is rotatably connected to the processing chamber 3, the adjusting mechanism 5 is tightly connected to the stirring mechanism 4, and the adjusting mechanism 5 is used to adjust the air intake of the combustion chamber 2.

[0031] The present invention utilizes tail gas generated by producing white phosphorus as fuel to heat mud phosphorus, so that phosphorus in the mud phosphorus is heated and vaporized for recovery. First, mud phosphorus to be recovered is placed in a processing chamber 3, and tail gas is introduced into a combustion chamber 2 for ignition, so that heat is transferred to the mud phosphorus in the processing chamber 3, so that white phosphorus in the mud phosphorus is heated and vaporized. In order to ensure that the mud phosphorus in the processing chamber 3 is heated evenly, stirring is performed by a stirring mechanism 4. An adjusting mechanism 5 is used to judge the distribution of the mud phosphorus in the processing chamber 3, and can specifically adjust the air intake at the corresponding position according to the distribution amount of the mud phosphorus at different positions in the processing chamber 3, so that the temperature distribution in the combustion chamber 2 is matched with the mud phosphorus distribution in the processing chamber 3, thereby improving the heating efficiency of the mud phosphorus.

[0032] The stirring mechanism 4 includes a driving motor 41, a main shaft 42 and stirring blades 43. The driving motor 41 is tightly connected to the casing 1, the output end of the driving motor 41 is transmission-connected to the main shaft 42, the main shaft 42 is rotationally connected to the processing chamber 3, the stirring blades 43 are tightly connected to the main shaft 42, and several groups of stirring blades 43 are arranged on the main shaft 42.

[0033] The driving motor 41 is the main power source of the stirring mechanism 4. The driving motor 41 outputs torque, thereby driving the main shaft 42 to rotate in the processing chamber 3, so that the stirring blade 43 rotates at a low speed in the processing chamber 3, thereby turning over the mud phosphorus in the processing chamber 3, making it heated evenly, thereby improving the heating efficiency.

[0034] A movable groove 431 is provided on the stirring blade 43, and a force block 44 is slidably connected to the movable groove 431. The force block 44 is located on the material-facing surface of the stirring blade 43. A liquid storage cavity 421 is provided in the main shaft 42. The movable groove 431 is connected to the liquid storage cavity 421, and the liquid storage cavity 421 is connected to the adjustment mechanism 5.

[0035] Hydraulic oil is filled in the movable groove 431 and the liquid storage chamber 421. When the stirring blade 43 contacts the mud phosphorus in the processing chamber 3 during rotation, the mud phosphorus will exert a reaction force on the force block 44, causing the force block 44 to slide along the movable groove 431, thereby pressing the hydraulic oil in the movable groove 431 into the liquid storage chamber 421, and transmitting the pressure to the liquid storage chamber 421; because the stirring blades 43 are arranged in several groups on the main shaft 42, and the distribution of the mud phosphorus in the processing chamber 3 is uneven, when a group of stirring blades 43 contacts an area with more mud phosphorus, because the weight of the mud phosphorus in this area is large, the reaction force on the force block 44 is greater, the sliding distance of the force block 44 along the movable groove 431 is longer, and the pressure transmitted to the liquid storage chamber 421 is greater.

[0036] The regulating mechanism 5 includes a sensing component 51 and an air supply component 52. The sensing component 51 is fastened to the main shaft 42 and is used to judge the distribution of mud phosphorus in the processing chamber 3. The air supply component 52 is fastened to the casing 1 and is used to adjust the air intake volume.

[0037] The sensing component 51 can determine the distribution of mud phosphorus in the processing chamber 3 by analyzing the pressure changes in the liquid storage chamber 421, and then introduce outside air through the air supply component 52 to change the oxygen content in different areas of the combustion chamber 2. The more mud phosphorus is distributed in an area, the more oxygen will be introduced into the combustion chamber 2, thereby promoting combustion and increasing the temperature of the corresponding area. The temperature of different areas is automatically adjusted according to the distribution of mud phosphorus, thereby improving the heating efficiency of the mud phosphorus.

[0038] There are several sensing components 51 arranged along the circumference of the main shaft 42, and the sensing components 51 include a connecting column 511, a slider 512, a movable magnet 513 and a reset spring 514. The connecting column 511 is tightly connected to the main shaft 42, and an adjusting groove 5111 is provided in the connecting column 511. The adjusting groove 5111 is communicated with the liquid storage chamber 421, and the slider 512 is slidingly connected to the adjusting groove 5111. One end of the reset spring 514 is tightly connected to the inner wall of the adjusting groove 5111, and the other end of the reset spring 514 is tightly connected to the slider 512. The reset spring 514 is located at one end of the adjusting groove 5111 close to the main shaft 42, and the movable magnet 513 is tightly connected to the slider 512, and the movable magnet 513 is located at one end of the adjusting groove 5111 away from the main shaft 42.

[0039] The connecting column 511 is fixed on the main shaft 42 and serves as the main support of the sensing component 51. The more mud phosphorus is distributed in the processing chamber 3, the greater the reaction force on the force block 44 will be, and the greater the pressure transmitted to the liquid storage chamber 421 will be. Under the action of pressure, the slider 512 will be pushed to move along the adjustment groove 5111 in the direction away from the main shaft 42, and the reset spring 514 will be stretched under the force, thereby driving the moving magnet 513 to move toward the inner wall of the processing chamber 3, thereby reducing the relative distance between the moving magnet 513 and the processing chamber 3. In addition, the more mud phosphorus is distributed in the processing chamber 3, the closer the distance between the moving magnet 513 and the processing chamber 3 will be.

[0040] A protrusion 11 is provided on the casing 1, and the protrusion 11 passes through the combustion chamber 2 and is close to the outer wall of the processing chamber 3. An air guide channel 111 and a reciprocating groove 112 are provided in the protrusion 11. The air supply component 52 includes a first movable part 521 and a second movable part 522. The first movable part 521 is located in the reciprocating groove 112, and the second movable part 522 is located in the air guide channel 111. The second movable part 522 is arranged on both sides of the reciprocating groove 112. The air outlet end of the air guide channel 111 is connected to a gas pipeline 523, and the gas pipeline 523 is connected to the combustion chamber 2. A burner head 21 is provided in the combustion chamber 2, and the air outlet end of the gas pipeline 523 faces the burner head 21. The position of the burner head 21 corresponds to the stirring blade 43. A smoke exhaust port 22 is provided on the combustion chamber 2, and a partition 23 is provided between the burner heads 21.

[0041] The raised portion 11 on the casing 1 is used to accommodate the air supply component 52, so that the air supply component 52 is close to the processing chamber 3, so that the sensing component 51 and the air supply component 52 are linked, the air guide channel 111 and the reciprocating groove 112 in the raised portion 11 form a T-shape, the movable magnet 513 is used to drive the first movable member 521 to move, and the first movable member 521 is used to drive the second movable member 522 to move, and the outside air is transported to the gas pipeline 523 through the air guide channel 111, thereby introducing the outside air into the combustion chamber 2 to increase the oxygen content in the corresponding area, thereby increasing the combustion temperature at the corresponding position of the combustion head 21, and the combustion heads 21 are separated by partitions 23, so that the processing chamber 3 can be heated in zones, and the temperature between each zone can be automatically adjusted according to the mud phosphorus distribution amount detected by the sensing component 51, so as to realize automatic adjustment of the temperature of different areas according to the distribution of mud phosphorus.

[0042] The first movable part 521 includes a movable magnet 5211 and a movable spring 5212. The movable magnet 5211 is slidably connected to the reciprocating groove 112. One end of the movable spring 5212 is firmly connected to the movable magnet 5211. The other end of the movable spring 5212 is firmly connected to the wall of the reciprocating groove 112. The facing ends of the movable magnet 5211 and the movable magnet 513 are opposite poles.

[0043] Because the positions of the air supply component 52 and the sensing component 51 are corresponding, when the sensing component 51 rotates at a fixed speed driven by the main shaft 42, the movable magnet 513 will continuously approach and move away from the active magnet 5211. According to the principle of opposites attract, when the movable magnet 513 approaches the active magnet 5211, the active magnet 5211 will overcome the elastic force of the active spring 5212 and move along the reciprocating groove 112 toward the processing chamber 3, thereby drawing air into the air guide channel 111. When the movable magnet 513 moves away from the active magnet 5211, the attraction between the two becomes smaller, and the active magnet 5211 will move to the other side along the reciprocating groove 112 under the action of the elastic force of the active spring, thereby pressing the inhaled air into the air guide channel 111. When it moves, it can drive the movable magnet 5211 to continuously reciprocate along the reciprocating groove 112, thereby continuously inhaling air; and because the more areas with mud phosphorus distributed in the processing chamber 3, the closer the distance between the movable magnet 513 and the processing chamber 3 is, that is, the closer the distance between the movable magnet 513 and the movable magnet 5211 is, the greater the magnetic force between the two, and the longer the distance the movable magnet 5211 moves along the reciprocating groove 112, the more air is inhaled, and the more oxygen is delivered to the combustion head 21 at the corresponding position, that is, it is realized that according to the distribution of mud phosphorus in the processing chamber 3, the air content input into different areas in the combustion chamber 2 is automatically adjusted, so that the temperature of different areas in the combustion chamber 2 is adaptively adjusted according to the distribution of mud phosphorus, and the more areas with mud phosphorus distribution have higher temperatures, thereby improving the heating efficiency.

[0044] The second movable part 522 includes a fixing ring 5221, a clamping head 5222, a clamping spring 5223 and a connecting seat 5224. The fixing ring 5221 and the connecting seat 5224 are fastened to the inner wall of the air guide channel 111. The clamping head 5222 abuts against the fixing ring 5221. The clamping spring 5223 is arranged between the clamping head 5222 and the connecting seat 5224. The connecting seat 5224 is provided with a flow hole.

[0045] In the initial state, the pressing head 5222 is pressed against the surface of the fixing ring 5221 under the elastic force of the pressing spring 5223. At this time, the air guide channel is in a closed state. When the first movable member 521 moves along the reciprocating groove 112 toward the side close to the processing chamber 3, the volume of the connecting part between the reciprocating groove 112 and the air guide channel 111 increases, thereby generating negative pressure, so that the pressing head 5222 on the air inlet side can overcome the elastic force of the pressing spring 5223, and the air passes through the connecting seat 5224. The air flows into the air guide channel 111 through the flow hole. When the first movable part 521 moves away from the processing chamber 3, the pressure in the reciprocating groove 112 increases. The clamping head 5222 on the air outlet side overcomes the elastic force of the clamping spring 5223, and the air flows into the air delivery pipe 523. Therefore, when the first movable part 521 continuously reciprocates in the reciprocating groove 112, the air will be continuously drawn into and pressed out of the air guide channel 111, thereby increasing the oxygen content in the combustion chamber 2 at the corresponding position and promoting combustion.

[0046] The stirring blade 43 is fan-shaped, and the cross-sectional area of ​​the adjusting groove 5111 is one twentieth of the cross-sectional area of ​​the force-bearing block 44 .

[0047] The fan-shaped stirring blade 43 can increase the contact area with the mud, thereby increasing the force on the force block 44. The cross-sectional area of ​​the adjustment groove 5111 is smaller than the cross-sectional area of ​​the force block 44, which can amplify the moving distance of the force block 44, thereby increasing the adjustment range of the movable magnet 513 in the adjustment groove 5111.

[0048] One end of the processing chamber 3 is provided with a feed inlet and a discharge outlet.

[0049] Mud phosphorus enters from the feed port of the treatment chamber 3, and the white phosphorus after being heated and vaporized is discharged through the discharge port.

[0050] Working principle of the present invention: the positions of the air supply component 52 and the sensing component 51 are corresponding to each other, so when the sensing component 51 is driven by the main shaft 42 and rotates at a fixed speed, the movable magnet 513 will continuously approach and move away from the movable magnet 5211. According to the principle of opposites attract, when the movable magnet 513 approaches the movable magnet 5211, the movable magnet 5211 will overcome the elastic force of the movable spring 5212 and move along the reciprocating groove 112 toward the processing chamber 3 to draw air into the air guide channel 111. When the movable magnet 513 moves away from the movable magnet 5211, the attraction between the two becomes smaller, and the movable magnet 5211 will move to the other side along the reciprocating groove 112 under the elastic force of the movable spring, thereby pressing the inhaled air into the air guide channel 111. When it is driven to rotate, it can drive the movable magnet 5211 to continuously reciprocate along the reciprocating groove 112, thereby continuously inhaling air; and because the more areas with mud phosphorus distributed in the processing chamber 3, the closer the distance between the movable magnet 513 and the processing chamber 3, that is, the closer the distance between the movable magnet 513 and the movable magnet 5211, the greater the magnetic force between the two, and the longer the distance the movable magnet 5211 moves along the reciprocating groove 112, the more air is inhaled, and the more oxygen is delivered to the combustion head 21 at the corresponding position, that is, it realizes automatic adjustment of the air content input into different areas of the combustion chamber 2 according to the distribution of mud phosphorus in the processing chamber 3, so that the temperature of different areas in the combustion chamber 2 is adaptively adjusted according to the distribution of mud phosphorus, and the more areas with mud phosphorus distribution have higher temperatures, thereby improving the heating efficiency.
