Detailed implementation manner
[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0027] The following gives specific embodiments.
[0028] As Figures 1 to 6As shown in the figure, a transmission and debugging device for the production of chloromethyl methyl ether according to an embodiment of the present utility model includes a pair of reaction kettles 1; an air extraction assembly is provided between the pair of reaction kettles 1; a top cover 18 is provided on the top of the reaction kettle 1; an outer shell 11 is provided outside the reaction kettle 1; a heating pipe 12 is fixedly connected to the middle of the side wall of the outer shell 11; an air outlet hole is provided in the middle of the side wall of the heating pipe 12; a ventilation hole 13 is provided in the middle of the side wall of the outer shell 11; the ventilation hole 13 and the air outlet hole are arranged correspondingly; a plurality of grooves 110 are provided in the middle of the inner side wall of the outer shell 11; a plurality of limiting blocks 14 are fixedly connected to the inner side wall of the groove 110; a heat insulation plate 15 is slidably matched with the inner side wall of the groove 110; the heat insulation plate 15 covers a plurality of ventilation holes 13; a fixing rod 16 is fixedly connected to the top side wall of the heat insulation plate 15; the fixing rod 16 is arranged above the top cover 18; an air extraction pipe 17 is provided on the top side wall of the top cover 18; the air extraction pipe 17 is connected to the air extraction assembly; a first liquid inlet pipe 19 is fixedly connected to the top side wall of one side of the top cover 18; a feeding assembly is fixedly connected to the top side wall of the other side of the top cover 18; the first liquid inlet pipe 19 and the reaction kettle 1 are both hollow and communicated; a mixing assembly is provided on the top side wall of the top cover 18;During operation, chemical workers inject chlorine and hydrogen into the internal of one side of the reaction kettle 1 through the first liquid inlet pipe 19. Subsequently, the mixing component is started to fully mix the gases inside and cause a chemical reaction. At this time, the chemical workers connect the heating pipe 12 to the hot air blower, and then pull up the heat insulation board 15. The heat insulation board 15 moves inside the groove 110, exposing a plurality of ventilation holes 13 covered by the heat insulation board 15. The exposed plurality of ventilation holes 13 can blow the hot air inside the heating pipe 12 towards the outer wall of the reaction kettle 1 to heat the reaction kettle 1. The temperature at which chlorine and hydrogen react to form hydrogen chloride gas should be controlled at seventy degrees Celsius. Pull the heat insulation board 15 to control the number of exposed ventilation holes 13, so that the temperature of the internal of the reaction kettle 1 heated by the ventilation holes 13 is always maintained at about seventy degrees Celsius. At this time, chlorine and hydrogen react to form hydrogen chloride gas. Subsequently, the chemical workers start the air extraction component to draw the hydrogen chloride gas from the extraction pipe 17 into the internal of the reaction kettle 1 on the other side, and then inject methanol and formaldehyde into the internal of the reaction kettle 1 on this side through the feeding component. Subsequently, the mixing component is started to fully mix the gases inside and cause a chemical reaction. The temperature at which chloromethyl methyl ether is formed should not exceed forty degrees Celsius. Similarly, pull the heat insulation board 15 to control the number of exposed ventilation holes 13, so that the temperature of the internal of the reaction kettle 1 heated by the ventilation holes 13 is always maintained at about forty degrees Celsius. At this time, methanol, formaldehyde and hydrogen chloride undergo a chlorination reaction to form chloromethyl methyl ether. In this step, by setting the heating pipe 12, ventilation holes 13, limit blocks 14, heat insulation board 15 and fixing rods 16, the temperatures for generating hydrogen chloride gas and chloromethyl methyl ether can be adjusted respectively. Excessively high temperature inside the reaction kettle 1 will cause hydrogen chloride gas and chloromethyl methyl ether to decompose or deteriorate, thus affecting the quality and stability of the generated hydrogen chloride gas and chloromethyl methyl ether. Adjusting the temperature can ensure that the product maintains its original chemical properties during the generation process. At the same time, adjusting the reaction temperature also helps to reduce the generation of impurities, thereby improving the purity of the product.;
[0029] Such as Figures 1 to 4As shown, the feeding component includes a plurality of second liquid inlet pipes 2; a baffle 21 is slidably fitted to the bottom side wall of the second liquid inlet pipe 2; the other side of the baffle 21 is arranged outside the top cover 18; a liquid extraction pipe 22 is fixedly connected to the middle of the side wall of the second liquid inlet pipe 2; a liquid extraction port 23 is provided at the end of the liquid extraction pipe 22; the second liquid inlet pipe 2, the liquid extraction pipe 22 and the reaction kettle 1 are all hollow and connected; during operation, chemical workers inject methanol and formaldehyde into the different second liquid inlet pipes 2 respectively to ensure that the ratio of methanol to formaldehyde is 1:2.39. When the solution in the second liquid inlet pipe 2 is injected too much, the chemical worker connects the syringe to the liquid extraction pipe 22 through the liquid extraction port 23 to extract the excess dose. Then, the baffle 21 is pulled open, and the baffle 21 will leave the bottom of the second liquid inlet pipe 2, so that the liquid in the second liquid inlet pipe 2 can smoothly enter the inside of the reaction kettle 1. By setting the second liquid inlet pipe 2, the baffle 21, the liquid extraction pipe 22 and the liquid extraction port 23, the ratio of methanol and formaldehyde can be accurately adjusted to ensure that the reaction proceeds under the best conditions. And the appropriate ratio helps to reduce the generation of unnecessary by-products, thereby improving the yield of chloromethyl methyl ether. At the same time, chloromethyl methyl ether is a flammable, explosive and toxic chemical. Accurately adjusting the ratio of reactants helps to reduce the safety risks during the reaction and ensure the life safety of chemical workers.
[0030] As Figures 1 to 5 shown, the mixing component includes a first motor 3; the first motor 3 is arranged on the top of the top cover 18; the output end of the first motor 3 is fixedly connected with a rotating rod 31; a plurality of stirring blades 32 are fixedly connected to the middle of the side wall of the rotating rod 31; during operation, after chlorine and hydrogen come into contact, the first motor 3 is started. The first motor 3 drives the rotating rod 31 to rotate, so that a plurality of stirring blades 32 on the side wall of the rotating rod 31 rotate synchronously. At this time, the stirring blades 32 will stir chlorine and hydrogen, causing chlorine and hydrogen to collide in the reaction kettle 1. At the same time, after methanol, formaldehyde and hydrogen chloride come into contact, the first motor 3 is started. The first motor 3 drives the rotating rod 31 to rotate, so that a plurality of stirring blades 32 on the side wall of the rotating rod 31 rotate synchronously. At this time, the stirring blades 32 will stir methanol, formaldehyde and hydrogen chloride, causing methanol, formaldehyde and hydrogen chloride to collide in the reaction kettle 1. By setting the first motor 3, the rotating rod 31 and the stirring blades 32, the gas and liquid can be more evenly distributed inside the reaction kettle 1, increasing the contact area and contact opportunity between them, which is beneficial to accelerating the reaction rate.
[0031] As Figure 4 and Figure 5As shown, a fixing seat 4 is fixedly connected to the bottom side wall of the top cover 18; the fixing seat 4 and the reactor 1 are arranged correspondingly; a plurality of fixing blocks 41 are fixedly connected to the middle of the side wall of the fixing seat 4; a plurality of first grooves 42 are opened in the middle of the inner side wall of the reactor 1; the first grooves 42 and the fixing blocks 41 are arranged correspondingly; a second groove 43 is opened in the middle of the inner side wall of the reactor 1; the second groove 43 and the fixing blocks 41 are arranged correspondingly; during operation, before the top cover 18 is covered on the top of the reactor 1, the chemical personnel first adjust the position of the top cover 18 so that the plurality of fixing blocks 41 are respectively aligned with the first grooves 42, and then the fixing blocks 41 are inserted into the first grooves 42. At this time, the top cover 18 is covered on the top of the reactor 1, and the fixing blocks 41 enter the second grooves 43. At this time, the chemical personnel rotate the top cover 18 again, so that the fixing block 41 slides inside the second groove 43 and is staggered with the first groove 42. This step can seal the reactor 1 by setting the fixing seat 4, the fixing block 41, the first groove 42 and the second groove 43 to prevent the reactants inside the reactor 1 from volatilizing into the air and causing waste of raw materials. Methanol, formaldehyde and hydrogen chloride are all highly volatile chemicals. When they accumulate to a certain concentration in the air, they will form an explosive mixture, increasing the risk of fire and explosion. Increasing the sealing of the reactor 1 can reduce this risk. At the same time, this arrangement will prevent the top cover 18 from falling off easily when the reactor 1 encounters shaking or bumping, thereby avoiding the adverse effects caused by the separation of the top cover 18 from the reactor 1.
[0032] like Figure 1 , Figure 2 and Figure 6 As shown, the vacuum assembly includes a vacuum box 5; the vacuum box 5 is fixedly connected between a pair of vacuum pipes 17; a second motor 51 is fixedly connected to the middle of the inner wall of the vacuum box 5; a connecting rod 52 is fixedly connected to the output end of the second motor 51; a plurality of fan blades 53 are fixedly connected to the middle of the side wall of the connecting rod 52; a thin rope 54 is fixedly connected to the middle of the side wall of the fan blade 53; a ball block 55 is fixedly connected to the end of the thin rope 54; the thin rope 54 and the ball block 55 are both made of elastic material; during work, the chemical personnel start the second motor 51, and the second motor 51 drives the connecting rod 52 to rotate, so that the plurality of fan blades 53 on the side wall of the connecting rod 52 rotate, and the fan blades 53 will generate Hydrogen chloride is pumped from the reactor 1 on one side into the reactor 1 on the other side. When the fan blades 53 rotate, the thin rope 54 and the ball block 55 are pulled to swing inside the vacuum box 5. At this time, multiple ball blocks 55 will continuously knock on the inner wall of the vacuum box 5 to shake off the gas attached to the inner wall of the vacuum box 5. In this step, the gas can be knocked off from the inner wall of the vacuum box 5 by the ball blocks 5, thereby reducing the local concentration difference inside the reactor 1 caused by the gas attached to the inner wall of the vacuum box 5, affecting the uniformity of the reaction, and the gas attached to the surface of the vacuum box 5 will corrode the vacuum box 5. The gas can be knocked off from the inner wall of the vacuum box 5 by knocking, which can reduce the occurrence of corrosion and extend the service life of the vacuum box 5.
[0033] As Figures 1 to 4 shown, a sealing ring 6 is fixedly connected to the middle of the side wall of the top cover 18; the sealing ring 6 is sleeved on the end of the air extraction pipe 17; by setting the sealing ring 6 in this step, it can tightly fill the gap at the connection between the air extraction pipe 17 and the top cover 18, forming an effective sealing barrier and reducing the possibility of gas leakage from the connection.
[0034] As Figures 1 to 2 shown, a protective shell 7 is provided outside the reaction kettle 1; the protective shell 7 covers the outside of the heating pipe 12; by setting the protective shell 7 outside the heating pipe 12 in this step, the heat dissipated from the heating pipe 12 to the outside can be reduced, the heating efficiency can be improved, and the heating speed can be accelerated.
[0035] Working principle: Chemical workers inject chlorine and hydrogen into the reactor 1 on one side through the first liquid inlet pipe 19, and then start the mixing component to fully mix the gases inside and cause a chemical reaction. At this time, the chemical workers connect the heating tube 12 to the hot air blower, and then pull the insulation board 15 upward. The insulation board 15 moves inside the groove 110 to expose multiple vents 13 covered by the insulation board 15. The exposed multiple vents 13 can blow the hot air inside the heating tube 12 to the outer wall of the reactor 1 to heat the reactor 1. The temperature of the hydrogen chloride gas generated by chlorine and hydrogen should be controlled at 70 degrees Celsius. The insulation board 15 is pulled to control the number of vents 13 exposed, so that the temperature of the reactor 1 heated by the vents 13 is always maintained at 70 degrees Celsius. At this time, chlorine and hydrogen react to generate hydrogen chloride gas. Then, the chemical personnel start the exhaust component to extract the hydrogen chloride gas from the exhaust pipe 17 into the reactor 1 on the other side, and then inject methanol and formaldehyde into the reactor 1 on this side through the feeding component. Then, the mixing component is started to fully mix the gases inside and react chemically. The temperature of chloromethyl methyl ether generation cannot exceed 40 degrees Celsius. Similarly, the insulation board 15 is pulled to control the number of vents 13 exposed, so that the temperature of the reactor 1 heated by the vents 13 is always maintained at about 40 degrees Celsius. At this time, methanol, formaldehyde and hydrogen chloride undergo chlorination reaction to generate chloromethyl methyl ether. The chemical personnel inject methanol and formaldehyde into different second liquid inlet pipes 2 respectively to ensure that methanol and formaldehyde The ratio is 1:2.39. When too much solution is injected into the second liquid inlet pipe 2, the chemical personnel connect the needle tube with the liquid extraction pipe 22 through the liquid extraction port 23 to extract the excess dose, and then pull open the baffle 21. The baffle 21 will leave the bottom of the second liquid inlet pipe 2, so that the liquid in the second liquid inlet pipe 2 can smoothly enter the reactor 1. After the chlorine and hydrogen come into contact, the first motor 3 is started, and the first motor 3 drives the rotating rod 31 to rotate, so that the multiple stirring blades 32 on the side wall of the rotating rod 31 rotate synchronously. At this time, the stirring blades 32 will stir the chlorine and hydrogen, so that the chlorine and hydrogen collide in the reactor 1. At the same time, after the methanol, formaldehyde and hydrogen chloride come into contact, the first motor 3 is started, and the first motor 3 drives the rotating rod 31 to rotate, so that the multiple stirring blades 32 on the side wall of the rotating rod 31 rotate synchronously. The stirring blades 32 rotate synchronously. At this time, the stirring blades 32 will stir methanol, formaldehyde and hydrogen chloride, causing methanol, formaldehyde and hydrogen chloride to collide in the reactor 1. Before covering the top cover 18 on the top of the reactor 1, the chemical personnel first adjust the position of the top cover 18 so that the multiple fixed blocks 41 are respectively aligned with the first groove 42, and then insert the fixed blocks 41 into the first groove 42. At this time, the top cover 18 is covered on the top of the reactor 1. When the fixed block 41 enters the second groove 43, the chemical personnel rotate the top cover 18 again, so that the fixed block 41 slides in the second groove 43 and is staggered with the first groove 42. The chemical personnel start the second motor 51, and the second motor 51 drives the connecting rod 52 to rotate, so that the multiple blades 53 on the side wall of the connecting rod 52 rotate.When the fan blade 53 rotates, it will draw the generated hydrogen chloride from one side of the reaction kettle 1 into the reaction kettle 1 on the other side. When the fan blade 53 rotates, it will pull the thin rope 54 and the ball block 55 to swing inside the air extraction box 5. At this time, multiple ball blocks 55 will continuously knock on the inner wall of the air extraction box 5 to shake off the gas attached to the inner wall of the air extraction box 5. By setting the sealing ring 6, it can tightly fill the gap at the connection between the air extraction pipe 17 and the top cover 18 to form an effective sealing barrier and reduce the possibility of gas leakage from the connection. By setting the protective shell 7 outside the heating pipe 12, the heat dissipated from the heating pipe 12 to the outside can be reduced, the heating efficiency can be improved, and the heating speed can be accelerated.
