Description

Technical Field

[0001] The present invention relates to the technical field of calcium oxide production equipment, and more particularly to a calcium oxide preparation device. Background Art

[0002] Nowadays, when producing calcium oxide, a large amount of solution is usually added to a container, and then mixed and stirred. This will cause uneven stirring of the solution and inaccurate control of the amount of solution added to the container, resulting in poor accuracy.

[0003] To solve the above problems, Chinese Patent CN211754079U discloses a device for producing calcium oxide, which includes a quartz box. An inlet structure and a stirring structure are provided on the quartz box. The inlet structure includes an inlet pipe, an inlet box, a spiral shaft, spiral blades, a first motor, an electromagnetic flowmeter, a solenoid valve, and a liquid adding pipe. The inlet pipe is inserted into the wall of the quartz box, the inlet box is installed at one end of the inlet pipe, the spiral shaft is inserted into the inlet box, and the spiral blades are installed on the spiral shaft. This device can control the amount and speed of the added solution through the inlet structure, ensuring accuracy. And the solution is stirred through the stirring structure to ensure the evenness of the solution stirring.

[0004] The above device has the following problems in actual use: 1. In this device, marble powder first reacts with pure nitric acid to form calcium nitrate, and then the calcium nitrate is heated in the quartz box. At high temperature, calcium nitrate decomposes into calcium oxide, nitrogen dioxide, nitrogen, and oxygen. However, nitrogen dioxide is a harmful gas. Therefore, the device does not purify nitrogen dioxide before it is discharged from the quartz box, so that the nitrogen dioxide discharged outside the quartz box will pollute the environment and harm the life and health of the staff. 2. When heating the solution, the heating wire is fixed on the side wall of the quartz box to heat the solution. However, when heating and decomposing the solution, it is required that the solution be heated evenly. Therefore, the device only heats the solution on both sides of the heating wire. The solution near both sides of the heating wire can be directly heated by the heating wire, while the solution far from both sides of the heating wire can only be heated by the heat transfer of the solution near the two sides of the heating wire. That is, the solution near both sides of the heating wire has a fast heating rate, and the solution far from both sides of the heating wire has a slow heating rate, resulting in uneven heating of the solution in the quartz box and thus prolonging the time for preparing calcium oxide. Summary of the Invention

[0005] The present invention provides a calcium oxide preparation device to solve the problem that nitrogen dioxide generated during the thermal decomposition of calcium nitrate at high temperature will pollute the environment and harm the life and health of the staff.

[0006] To achieve the above object, the present invention adopts the following technical solution: A calcium oxide preparation device, comprising a box body and a stirring mechanism; a feeding pipe is communicated with the box body; the stirring mechanism is arranged at the bottom of the box body: further comprising a plurality of purification mechanisms; the purification mechanism comprises a purification box, a purification component and a driving component for driving the purification box to reciprocate in the width direction of the box body; the purification box is slidably connected to the top of the box body; a purification chamber is opened in the purification box, an air outlet hose is communicated with the purification chamber, and a switch valve is arranged on the air outlet hose; the purification component comprises a purification pipe, a rotation induction switch, a moving part for driving the purification pipe to rotate and a purification part for treating harmful gases in the purification chamber; the purification pipe is rotatably connected to the purification chamber; the rotation induction switch and the purification part are both arranged on the purification pipe; further comprising a heating element for heating the solution and a suction part for pumping the gas in the box body into the purification chamber.

[0007] The principle and advantages of this solution are as follows: The solution is transported into the box body through the feeding pipe, and the stirring mechanism continuously stirs the solution. While the stirring mechanism is stirring, the heating element heats the solution; after heating for a period of time, the solution is thermally decomposed into calcium oxide, nitrogen dioxide and other gases. At this time, the driving component drives the purification box to reciprocate on the top of the box body in the width direction of the box body; during the reciprocating movement of the purification box, the suction part continuously sucks the gas in the box body into the purification chamber, the moving part drives the purification pipe to rotate, the rotation induction switch is turned on, and the purification part starts to work. Under the action of the purification part, the harmful gases in the gas are treated, and the treated harmful gases are discharged through the air outlet hose.

[0008] In the prior art, marble powder first reacts with pure nitric acid to form calcium nitrate, and then calcium nitrate is heated in a quartz box. At high temperature, calcium nitrate decomposes into calcium oxide, nitrogen dioxide, nitrogen and oxygen. However, nitrogen dioxide is a harmful gas. Therefore, the device does not purify nitrogen dioxide before it is discharged from the quartz box, and the nitrogen dioxide discharged outside the quartz box will pollute the environment and harm the life and health of the staff; compared with the prior art, after the solution is put into the box body in the present invention, the stirring mechanism will fully stir the solution. Since the heating element is also heating the solution while stirring; during the heating process, the heated solution will move violently, and the solution has fluidity, so that the solution can move to different positions in the box body and mix with the solution at different positions; that is, under the combined action of the stirring mechanism and the heating element, the solution is stirred more fully and the solution is mixed more completely.

[0009] After heating for a period of time, the solution begins to decompose into gases such as calcium oxide and nitrogen dioxide. At this time, the driving component drives the purification box to reciprocate on the box body along the width direction of the box body; during the reciprocating movement of the purification box, the suction part continuously sucks the gas into the purification chamber. At the same time, the purification pipe rotates under the drive of the moving part, the rotation induction switch is turned on, and the purification part starts to work; during the rotation of the purification pipe, the purification part introduces the purification liquid into the purification pipe. During the rotation of the purification pipe, the purification liquid is sprayed out of the purification pipe, and the nitrogen dioxide and other gases sucked into the purification chamber are processed by the purification liquid and become gases that are harmless to the environment and the staff.

[0010] Further, the driving component includes a first slider, a chute opened on the inner wall of the box body, and a linkage part for driving the first slider to reciprocate; the first slider is slidably connected to the chute; the first slider is fixedly connected to the purification box.

[0011] The linkage part drives the first slider to reciprocate in the chute; when the first slider moves along the width direction of the box body, the purification box moves synchronously with the first slider.

[0012] Further, the moving part includes a movable block, a rotating shaft, a belt, and a communication groove opened on the inner wall of the box body; the communication groove communicates with the chute; the movable block is fixedly connected to the first slider, and the movable block is slidably connected to the communication groove; the rotating shaft is rotatably connected to the movable block; the belt is arranged between the rotating shaft and the purification pipe; it also includes an adjustment unit for driving the rotating shaft to rotate; the purification part and the suction part work simultaneously with the rotation of the rotating shaft.

[0013] During the movement of the first slider, the movable block moves synchronously with the first slider, and further the movable block moves synchronously with the purification box, that is, the rotating shaft rotatably connected to the movable block also moves synchronously with the purification box; during the synchronous movement of the rotating shaft and the purification box, the suction part continuously sucks nitrogen dioxide and other gases into the purification chamber; during the operation of the suction part, the adjustment unit drives the rotating shaft to rotate, and under the action of the belt, the purification pipe rotates synchronously with the rotating shaft; when the purification pipe rotates, the rotation induction switch is turned on, and the purification part starts to work, that is, under the action of the adjustment unit, the purification part and the suction part start to work simultaneously with the rotation of the rotating shaft.

[0014] During the simultaneous operation of the suction part and the purification part, the suction part continuously sucks the gas into the purification chamber, and the harmful gases in the gas are all processed by the purification part.

[0015] Further, the adjusting unit includes an adjusting block, a rotating shaft, a first gear, a second gear, a third gear, a rack, a first guiding block for changing the position of the adjusting block, and a second guiding block for returning the adjusting block to the initial state; the adjusting block is slidably connected to the movable block, and the moving direction of the adjusting block is perpendicular to the moving direction of the movable block; the rotating shaft is rotatably connected to the adjusting block; the first gear and the third gear are both fixedly connected to the rotating shaft; the rack is fixedly connected to the inner wall of the box body, the rack is located below the first gear, the sum of the thickness of the first gear and the moving stroke of the adjusting block is not greater than the width of the rack, the length of the rack is less than the length of the sliding groove, and the rack meshes with the first gear; the second gear is fixedly connected to the rotating shaft, and the second gear can mesh with the third gear; the first guiding block and the second guiding block are respectively fixedly connected to both ends of the communication groove.

[0016] When the first slider drives the adjusting block to move in the communication groove along the width direction of the box body towards the direction of the first guiding block, the rotating shaft moves synchronously with the adjusting block, the first gear fixedly connected to the rotating shaft meshes with the rack, and then the first gear rotates, and the rotating shaft rotates synchronously with the first gear, that is, while the rotating shaft moves, the rotating shaft can also rotate.

[0017] When the first slider drives the adjusting block to move along the path of the communication groove to the position of the first guiding block, the adjusting block slides on the movable block under the action of the first guiding block; the moving direction of the adjusting block is perpendicular to the moving direction of the movable block, so that the rotating shaft moves synchronously with the adjusting block, and the first gear moves synchronously with the rotating shaft.

[0018] During the period when the first slider drives the adjusting block to move; since the sum of the thickness of the first gear and the moving stroke of the adjusting block is not greater than the width of the rack, therefore, after the first gear moves, the first gear can still mesh with the rack; and, since the length of the rack is less than the length of the sliding groove, therefore, before the adjusting block completes the position adjustment, the first gear and the third gear will stop moving first; the first slider drives the adjusting block to continue to move, and after a period of time when the first gear and the third gear stop rotating, the first gear and the third gear on the rotating shaft complete the position adjustment synchronously with the adjusting block, so that the third gear fixedly connected to the rotating shaft is juxtaposed with the second gear, and the second gear meshes with the third gear.

[0019] When the second gear meshes with the third gear, at this time, the first slider drives the adjusting block to move in the reverse direction along the path of the communication groove, that is, the first slider drives the adjustment to move in the direction of the second guide block along the path of the communication groove; during the reverse movement of the first slider, the third gear starts to rotate driven by the rotating shaft, and then the second gear rotates; after the second gear rotates, the rotating shaft rotates synchronously with the second gear, and under the action of the belt, the purification pipe rotates synchronously with the rotating shaft; until the first slider returns to the initial position, the first slider drives the adjusting block to move synchronously, so that under the action of the second guide block, the adjusting block resets, and the adjusting block also returns to the initial position, and the second gear no longer meshes with the third gear, and the rotating shaft no longer rotates.

[0020] Further, the purification part includes a hose and a plurality of purification holes opened on both sides of the purification pipe along the axial direction of the purification pipe; the hose extends into the box body and is communicated with the purification pipe.

[0021] During the reverse movement of the first slider, the purification pipe starts to rotate continuously. At this time, the purification chamber is already filled with a large amount of gases such as nitrogen dioxide; during this period, the rotation induction switch is turned on, and the purification liquid flows into the purification pipe through the hose, and then the purification liquid sprays out from the purification holes on both sides of the purification pipe; since the purification pipe can rotate, under the action of centrifugal force, the purification liquid has a greater impact force, and the gas located on the movement track of the purification liquid will be dispersed by the purification liquid, and the dispersed gas forms impact gas, and the impact gas has a higher moving speed and can quickly move to different positions in the purification chamber, so that the nitrogen dioxide in the gas can contact more purification liquid, and thus the nitrogen dioxide is mixed more completely with the purification liquid, and the nitrogen dioxide is absorbed more fully.

[0022] At the same time, during the spraying process of the purification liquid, due to the large impact force of the purification liquid, the purification liquid can act on the inner wall of the purification chamber. As the rotation of the purification pipe continues, the purification liquid sprays out from the purification holes, sprays towards the inner wall of the purification chamber and acts on the inner wall of the purification chamber. Then, the purification liquid is splashed in the opposite direction by the reaction force of the inner wall of the purification chamber and forms splashing liquid, and the splashing liquid has a certain acting force. The splashing liquid spreads around in the opposite direction at the inner wall of the purification chamber, and the splashing liquid will mix with the nitrogen dioxide in the purification chamber and absorb the nitrogen dioxide, becoming a gas that is harmless to the environment and the life and health of the staff.

[0023] When the purification pipe starts to rotate, the rotation induction switch is turned on, and the purification liquid is introduced into the purification pipe through the hose, which can save the amount of purification liquid used and avoid waste; secondly, at this time, the purification chamber is already filled with a large amount of gases such as nitrogen dioxide, and the hose then introduces the purification liquid into the purification pipe, and the purification liquid flying out of the purification pipe can contact more nitrogen dioxide, so that the nitrogen dioxide is treated more completely.

[0024] During the continuous rotation of the purification pipe, a large amount of nitrogen dioxide has been treated by the purification liquid. When the first slider returns to its initial state, at this time, the purification chamber is also filled with a large amount of purification liquid, the purification pipe stops rotating, and the rotation induction switch is turned off, saving the amount of purification liquid used; this reciprocating motion continues, and all the gases such as nitrogen dioxide in the box are absorbed into the purification chamber by the suction part. Under the treatment of the purification pipe, the nitrogen dioxide is removed and then discharged outside the purification chamber.

[0025] Furthermore, the suction part includes a piston, a piston cylinder, a gas storage chamber opened in the purification box, and a driving unit for driving the piston to reciprocate; the piston cylinder is fixedly connected to the gas storage chamber; an intake pipe is communicated between the piston cylinder and the interior of the box body, and a first one-way valve is provided on the intake pipe. An exhaust pipe is communicated between the piston cylinder and the purification chamber, and a second one-way valve is provided on the exhaust pipe; the piston is slidably connected to the piston cylinder.

[0026] During the reciprocating motion of the piston, it will continuously inhale and exhale; when the piston moves upward, the piston inhales, the first one-way valve opens, and the second one-way valve closes. Gases such as nitrogen dioxide enter the gas storage chamber from bottom to top through the intake pipe; when the piston moves downward, the piston exhales, the first one-way valve closes, and the second one-way valve opens. Gases such as nitrogen dioxide enter the purification chamber from bottom to top through the exhaust pipe; the first one-way valve and the second one-way valve can prevent the backflow of gases.

[0027] Furthermore, the driving unit includes a cam and a spring sleeved on the piston; the cam is fixedly connected to the rotating shaft, the sum of the thickness of the cam and the movement stroke of the adjusting block is not greater than the width of the piston, and the cam abuts against the piston; both ends of the spring are respectively connected to the piston and the piston cylinder.

[0028] As the rotating shaft rotates, the rotating shaft drives the cam to rotate; when the convex part of the cam abuts against the piston, the piston moves vertically upward; when the convex part of the cam no longer presses the piston, the piston returns under the action of the spring, and the piston moves vertically downward; the sum of the thickness of the cam and the movement stroke of the adjusting block is not greater than the width of the piston, which ensures that after the rotating shaft moves a certain distance driven by the adjusting block, the cam fixedly connected to the rotating shaft always abuts against the piston.

[0029] Furthermore, the linkage part includes a second slider, a guide rod, a rotating shaft, a guide groove opened on the inner wall of the box body, and a power part for driving the rotating shaft to rotate; the second slider is slidably connected to the guide groove; the rotating shaft is rotatably connected to the inner wall of the box body; the guide rod includes two guide rods, the two guide rods are respectively fixedly connected to both sides of the rotating shaft, and the distance between the two guide rods forms a rectangular groove, and the second slider is slidably connected to the rectangular groove; the first slider is slidably connected to the second slider.

[0030] The power component drives the rotating shaft to rotate. Driven by the guide rod, the second slider always slides in the guide groove and the rectangular groove at the same time. As the rotation of the rotating shaft continues, the second slider will reciprocate in the guide groove and the rectangular groove. In the initial state, the second slider is at the lowest point at one end of the guide groove. As the rotating shaft rotates, when the second slider moves from the initial position to the highest point of the guide groove, the movement path of the second slider is from bottom to top. When the second slider moves from the highest point of the guide groove to the lowest point at the other end of the guide groove, the movement path of the second slider is from top to bottom. That is, the second slider can perform vertical reciprocating motion along the depth direction of the box body.

[0031] During the reciprocating motion of the second slider, the first slider is always slidably connected to the second slider, and thus the first slider and the second slider always move synchronously. During the vertical reciprocating motion of the second slider, the first slider makes a vertical reciprocating relative motion on the second slider. At the same time, during the synchronous motion of the first slider and the second slider, the first slider can move from one end of the chute to the other end under the limitation of the chute. When the second slider resets, the first slider and the second slider reset synchronously.

[0032] Furthermore, the heating component is fixedly connected to the end face of the second slider away from the guide groove; the shape of the heating component is a semi-circular disk shape.

[0033] Since the second slider can move vertically, and during the vertical movement of the second slider, the second slider can move from one end of the guide groove to the other end of the guide groove, that is, while the second slider moves vertically, the second slider can also move horizontally. During this period, the heating component moves synchronously with the second slider.

[0034] When the heating component moves from the bottom to the middle position in the box body, the heating component will stir the solution. Then, under the stirring of the heating component, a part of the lower-layer solution in the box body moves to the middle position of the upper layer in the box body. During this period, the lower-layer solution can be mixed with the solution at different positions in the upper layer again. When the heating component moves from the middle position of the upper layer in the box body to the lower layer at the other end of the box body, under the stirring of the heating component, a part of the upper-layer solution in the box body moves to the lower layer at the other end of the box body. During this period, the upper-layer solution can be mixed with the lower-layer solution at the other end of the box body again. When the heating component returns to the initial position along the width direction of the box body from the other end of the box body, under the stirring of the heating component, the solution at the other end of the lower layer can be mixed with the solution at different positions in the lower layer again.

[0035] Through the reciprocating motion of the heating component, the solutions at different positions in the box body can be mixed with the solutions at other different positions again, that is, the solutions are in contact more completely and mixed more fully.

[0036] While the heating element is moving, the heating element can simultaneously heat the solution; since the heating element moves vertically and horizontally simultaneously and is located within the solution, the inner and outer surfaces of the solution can be evenly heated during the reciprocating movement of the heating element; with the continuous stirring of the stirring mechanism, the heated solution will move to the other end of the box, and the unheated solution will move onto the movement trajectory of the heating element, and the solution located on the movement trajectory of the heating element will be heated.

[0037] Through the combined action of the stirring mechanism and the heating element, the solution in the box is stirred and heated, which shortens the time for preparing calcium oxide and improves the production efficiency of calcium oxide.

[0038] The heating element is semi-circular in shape, increasing the contact area between the heating element and the solution, enabling more solution to be heated simultaneously, and ensuring that the solution is evenly heated during the reciprocating movement of the heating element.

[0039] Furthermore, the number of the purification mechanisms is two; the movement directions of the two purification mechanisms are opposite.

[0040] Since the movement directions of the two purification mechanisms are opposite, during the piston's inhalation and exhalation, there is a large amount of gas such as nitrogen dioxide around the piston for the piston to extract in the two purification boxes with opposite movement directions. The gas will not cause the balance of the forces on both sides of the gas due to the simultaneous inhalation of the two pistons, resulting in some gas between the two pistons not being extracted by the pistons, that is, the inhalation work of the two pistons will not conflict.

[0041] The movement directions of the two purification mechanisms are opposite, that is, the movement directions of the two second sliders are opposite; since the movement directions of the two second sliders are opposite, the movement directions of the two heating elements are also opposite; since the movement directions of the two heating elements are opposite, when the heating element heats and stirs the solution, the stirring mechanism will drive the solution onto the movement trajectory of the heating element at the other end, and then the heating element at the other end will heat and stir; similarly, the solution at the other end can also move to different positions in the box to be mixed with other solutions, and the solution will be heated during the mixing process.

[0042] The two purification mechanisms with opposite movement directions ensure that the air extraction of the two pistons does not affect each other, and under the combined action of the heating element and the stirring mechanism, while the solution is constantly changing positions, it can also be heated; that is, it ensures the sufficiency of the solution stirring and the uniform heating of the solution during the stirring process, shortens the preparation time of calcium oxide, and improves the production efficiency.

[0058] The linkage part includes a second slider 10, a guide rod 8, a rotating shaft 6, a guide groove 5 opened on the inner wall of the box body 1, and a power member for driving the rotating shaft 6 to rotate; the guide groove 5 is located above the communication groove 12, and the distance between the heating coil 4 and the first slider 9 is greater than the height of the guide groove 5, and the second slider 10 is slidably connected to the guide groove 5; the rotating shaft 6 is located at the center of the guide groove 5 and is rotatably connected to the inner wall of the box body 1; the guide rod 8 includes two guide rods, and the two guide rods are respectively fixedly connected to both sides of the rotating shaft 6, and the distance between the two guide rods forms a rectangular groove, and the second slider 10 is slidably connected to the rectangular groove; the first slider 9 is slidably connected to the second slider 10, and the second slider 10 extends into the bottom of the box body 1; the power member is a second motor, the second motor is fixedly connected to the outer wall of the box body 1, and the output shaft of the second motor is fixedly connected to the rotating shaft 6.

[0059] The heating member is fixedly connected to the end face of the second slider 10 far from the guide groove 5; the heating member is a heating coil 4, and the shape of the heating coil 4 is a semi-circular disk shape.

[0060] The specific implementation process is as follows:

[0061] The solution is transported into the box body 1 through the feeding pipe. While the solution enters the box body 1, the first motor is started, and the output shaft of the first motor drives the stirring shaft 2 to rotate, and then the stirring shaft 2 drives the stirring blades 3 to continuously stir the solution in the box body 1; while the stirring shaft 2 is stirring, the heating coil 4 is energized, and the energized heating coil 4 can heat the solution; after heating for a period of time, the solution is thermally decomposed into gases such as calcium oxide and nitrogen dioxide.

[0062] While the heating coil 4 is energized, the second motor is started. The output shaft of the second motor drives the rotating shaft 6 to rotate. During the rotation of the rotating shaft 6, the guide rods fixed on both sides of the rotating shaft 6 rotate synchronously with the rotating shaft 6. Driven by the guide rod 8, the second slider 10 always slides in the guide groove 5 and the rectangular groove at the same time. As the rotation of the rotating shaft 6 continues, the second slider 10 will reciprocate in the guide groove 5 and the rectangular groove. In the initial state, the second slider 10 is at the lowest point at one end of the guide groove 5. As the rotating shaft 6 rotates, when the second slider 10 moves from the initial position to the highest point of the guide groove 5, the movement path of the second slider 10 is from bottom to top. When the second slider 10 moves from the highest point of the guide groove 5 to the lowest point at the other end of the guide groove 5, the movement path of the second slider 10 is from top to bottom. That is, the second slider 10 can perform vertical reciprocating motion along the depth direction of the box body 1.

[0063] During the reciprocating motion of the second slider 10, the first slider 9 is always slidably connected to the second slider 10, and thus the first slider 9 and the second slider 10 always move synchronously;;; During the vertical reciprocating motion of the second slider 10, the first slider 9 makes a vertical reciprocating relative motion on the second slider 10. At the same time, during the synchronous motion of the first slider 9 and the second slider 10, the first slider 9 can move from one end of the chute 11 to the other end under the limitation of the chute 11. When the second slider 10 is reset, the first slider 9 and the second slider 10 are reset synchronously.

[0064] Since the second slider 10 can move vertically, and during the vertical movement of the second slider 10, the second slider 10 can move from one end of the guide groove 5 to the other end of the guide groove 5, that is, while the second slider 10 moves vertically, the second slider 10 can also move horizontally; During this period, the heating coil 4 moves synchronously with the second slider 10.

[0065] When the heating coil 4 moves from the bottom to the middle position inside the box body 1, the heating coil 4 will stir the solution. Then, under the stirring of the heating coil 4, a part of the solution in the lower layer inside the box body 1 moves to the middle position of the upper layer inside the box body 1. During this period, the solution in the lower layer can be mixed with the solution at different positions in the upper layer again; when the heating coil 4 moves from the middle position of the upper layer inside the box body 1 to the lower layer at the other end of the box body 1, under the stirring of the heating coil 4, a part of the solution in the upper layer moves to the lower layer at the other end inside the box body 1. During this period, the solution in the upper layer can be mixed with the solution in the lower layer at the other end inside the box body 1 again; when the heating coil 4 returns to the initial position along the width direction of the box body 1 from the other end of the box body 1, under the stirring of the heating coil 4, the solution in the lower layer at the other end inside the box body 1 can be mixed with the solution at different positions in the lower layer again. That is, through the reciprocating movement of the heating coil 4, the solutions at different positions inside the box body 1 can all be mixed with the solutions at other different positions again, that is, the solutions are in contact more completely and mixed more fully.

[0066] During the reciprocating movement of the heating coil 4, the heating coil 4 is heating the solution at the same time; since the heating coil 4 moves vertically and horizontally simultaneously and the heating coil 4 is located inside the solution, the inner and outer surfaces of the solution can be heated evenly during the reciprocating movement of the heating coil 4; with the continuous stirring of the stirring blade 3, the heated solution will move to the other end of the box body 1, and the unheated solution will move to the movement track of the heating coil 4, and the solution located on the movement track of the heating coil 4 will be heated.

[0067] The heating coil 4 is semi-circular in shape, increasing the contact area between the heating coil 4 and the solution, enabling more solution to be heated simultaneously, and ensuring that the solution is heated evenly during the reciprocating movement of the heating coil 4.

[0068] Under the combined action of the stirring blade 3 and the heating coil 4, the solution inside the box body 1 is all stirred and heated, shortening the time for preparing calcium oxide and improving the production efficiency of calcium oxide.

[0069] During the period when the stirring blade 3 and the heating coil 4 act together, the first slider 9 moves along the width direction of the box body 1 from one end of the chute 11 to the other end under the drive of the second slider 10. Since the first slider 9 is fixedly connected to the purification box 7, that is, the purification box 7 moves synchronously with the first slider 9. During the period when the purification box 7 moves synchronously with the first slider 9, the movable block 13 moves synchronously with the first slider 9, and the adjusting block 14 moves synchronously with the movable block 13, that is, the rotating shaft 18 rotatably connected to the adjusting block 14 also moves synchronously with the first slider 9. During the movement of the rotating shaft 18, the first gear 20 fixed to the rotating shaft 18 meshes with the rack 17, and then the first gear 20 rotates. The rotating shaft 18 rotates synchronously with the first gear 20, that is, while the rotating shaft 18 moves, the rotating shaft 18 can also rotate. As the rotating shaft 18 rotates, the rotating shaft 18 drives the cam 23 to rotate. When the convex part of the cam 23 abuts against the piston rod 24, the piston rod 24 moves vertically upward. When the convex part of the cam 23 no longer presses the piston rod 24, the piston rod 24 returns under the action of the spring 25, and the piston rod 24 moves vertically downward.

[0070] During the reciprocating movement of the piston body, it will continuously inhale and exhaust air. During the upward movement of the piston body, the piston body inhales air, the first one-way valve opens, and the second one-way valve closes. Gases such as nitrogen dioxide enter the air storage chamber 26 from bottom to top through the intake pipe. During the downward movement of the piston body, the piston body exhausts air, the first one-way valve closes, and the second one-way valve opens. Gases such as nitrogen dioxide enter the purification chamber 27 from bottom to top through the exhaust pipe. The first one-way valve and the second one-way valve can prevent the backflow of gases.

[0071] That is, the first slider 9 moves from one end of the chute 11 to the other end, and the piston body inhales most of the gases in the box body 1 into the purification chamber 27.

[0072] At the same time, during the movement of the first slider 9, the first slider 9 drives the movable block 13 to move in the communication groove 12 along the width direction of the box body 1 towards the direction of the first guide block 15, and the adjusting block 14 moves synchronously with the movable block 13. When the first slider 9 moves to the other end of the chute 11, the adjusting block 14 also moves to the position where the first guide block 15 is located. The adjusting block 14 slides on the movable block 13 under the action of the first guide block 15. The movement direction of the adjusting block 14 is perpendicular to the movement direction of the movable block 13, so that the rotating shaft 18 moves synchronously with the adjusting block 14, and the first gear 20 also moves synchronously with the rotating shaft 18.

[0073] During the movement of the first slider 9 driving the adjustment block 14, since the sum of the thickness of the first gear 20 and the movement stroke of the adjustment block 14 is not greater than the width of the rack 17, after the movement of the first gear 20, the first gear 20 can still mesh with the rack 17. And, since the length of the rack 17 is less than the length of the chute 11, before the adjustment block 14 completes the position adjustment, the first gear 20 and the third gear 22 will stop moving first. The first slider 9 drives the adjustment block 14 to continue moving. After a period of time when the first gear 20 and the third gear 22 stop rotating, the first gear 20 and the third gear 22 on the rotating shaft 18 complete the position adjustment synchronously with the adjustment block 14, so that the third gear 22 fixed on the rotating shaft 18 is juxtaposed with the second gear 21, and the second gear 21 meshes with the third gear 22.

[0074] When the second gear 21 meshes with the third gear 22, at this time, the first slider 9 drives the adjustment block 14 to move in the reverse direction along the path of the communication groove 12, that is, the first slider 9 drives the adjustment block 14 to move in the direction of the second guide block 16 along the path of the communication groove 12. During the reverse movement of the first slider 9, the third gear 22 starts to rotate driven by the rotating shaft 18, and then the second gear 21 rotates. After the second gear 21 rotates, the rotating shaft 19 rotates synchronously with the second gear 21. Under the action of the belt, the purification pipe 28 rotates synchronously with the rotating shaft 19. When the purification pipe 28 starts to rotate, the rotation induction switch is turned on, and the purification liquid flows into the purification pipe 28 through the hose, and then the purification liquid sprays out from the purification holes on both sides of the purification pipe 28. Until the first slider 9 returns to the initial position, the first slider 9 drives the adjustment block 14 to move in the reverse direction synchronously along the path of the communication groove 12. When the adjustment block 14 moves to the position of the second guide block 16, under the action of the second guide block 16, the adjustment block 14 is reset, and the adjustment block 14 also returns to the initial position. The second gear 21 no longer meshes with the third gear 22, and the rotating shaft 19 no longer rotates, that is, the rotation induction switch is turned off, and the hose no longer conveys the purification liquid into the purification pipe 28.

[0075] During the reverse movement of the first slider 9, since the purification pipe 28 can rotate, under the action of centrifugal force, the purification liquid sprayed out from the purification holes has a greater impact force. The gas located on the movement track of the purification liquid will be dispersed by the purification liquid, and the dispersed gas forms impact gas. The impact gas has a higher moving speed and can quickly move to different positions of the purification chamber 27. Then the nitrogen dioxide in the gas can contact more purification liquid, so that the nitrogen dioxide is mixed more completely with the purification liquid and the nitrogen dioxide is absorbed more fully.

[0076] At the same time, during the spraying process of the purification liquid, due to the large impact force of the purification liquid, the purification liquid can act on the inner wall of the purification chamber 27. As the continuous rotation of the purification pipe 28 proceeds, the purification liquid sprays out from the purification holes, sprays towards the inner wall of the purification chamber 27 and acts on the inner wall of the purification chamber 27. Then, the purification liquid is sputtered in the opposite direction by the reaction force of the inner wall of the purification chamber 27 to form sputtered liquid, and the sputtered liquid has a certain acting force. The sputtered liquid spreads around in the opposite direction at the inner wall of the purification chamber 27. The sputtered liquid will mix with the nitrogen dioxide in the purification chamber 27 and absorb the nitrogen dioxide. The treated gas is discharged through the air outlet hose and becomes a gas that is harmless to the environment and the lives and health of the staff.

[0077] The purification pipe 28 starts to move only when the first slider 9 moves in the reverse direction, which can save the purification liquid and avoid waste. Secondly, the purification chamber 27 is filled with a large amount of gases such as nitrogen dioxide. During the process of the purification pipe 28, the purification liquid sprayed out from the purification holes has a certain acting force. During the movement of the purification liquid, it can come into contact with more nitrogen dioxide, and thus the nitrogen dioxide is treated more completely. The purification liquid mixed with the nitrogen dioxide finally falls to the bottom of the purification chamber. After the preparation of calcium oxide is completed, the purification liquid is discharged through the drain pipe, which is convenient for the staff to collect.

[0078] Since the moving directions of the two purification boxes 28 are opposite, during the suction and exhaust of the pistons, for the two pistons with opposite moving directions, there is a large amount of gases such as nitrogen dioxide around the piston in the box body 1 for the piston to extract. The gas will not cause the acting forces on both sides of the gas to be balanced due to the simultaneous suction of the two pistons, resulting in some gas between the two pistons not being extracted by the pistons, that is, the suction work of the two pistons will not conflict.

[0079] The moving directions of the two purification boxes 28 are opposite, that is, the moving directions of the two second sliders 10 are opposite; since the moving directions of the two second sliders 10 are opposite, the moving directions of the two heating coils 4 are also opposite; the moving directions of the two heating coils 4 are opposite. Therefore, when the heating coils 4 heat and stir the solution, the stirring blades 3 will drive the solution to the moving track of the other heating coil 4, and then the other heating coil 4 will heat and stir it; similarly, the solution at the other end can also move to different positions in the box body 1 to be mixed with other solutions, and the solution is heated simultaneously during the mixing period.

[0080] That is, the two purification boxes 28 with opposite moving directions ensure that the air extraction of the two pistons is not affected by each other, and under the combined action of the heating coils 4 and the stirring blades 3, while the solution is constantly changing positions, it can also be heated; that is, it ensures the sufficiency of the solution stirring and the uniform heating of the solution during the stirring process.

Specific technical solutions and / or common knowledge such as characteristics well known in the art are not described in detail herein. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicability of the patent.
