Description

Technical Field

[0001] The present invention relates to the technical field of purification of dichloroacetyl chloride, and specifically relates to a purification system for dichloroacetyl chloride. Background Art

[0002] Dichloroacetyl chloride is a colorless and irritating liquid. It can be miscible with ether, decomposes when encountering water and alcohol, and smokes in the air. It is mainly used in organic synthesis and as an intermediate for pesticides and pharmaceuticals. It can be used for the synthesis of vinyl pesticides, and is also used for the shrink-proof finishing, bleaching, decolorization, preservation, sterilization, and disinfection of wool felt.

[0003] When purifying dichloroacetyl chloride, it is divided into an adsorption stage, a displacement stage, and a rectification stage. In the rectification step, rectification residues are likely to exist at the bottom of the rectification device. If the rectification residues containing dichloroacetyl chloride are directly discharged into an external water source, dichloroacetyl chloride reacts with water to produce toxic substances, which is highly toxic to aquatic organisms. For this reason, we previously proposed a dichloroacetyl chloride extraction device with the publication number (CN220495600U). By heating the residues, dichloroacetyl chloride vaporizes and rises, and then enters the second box through the first pipeline. The filter screen filters the gaseous dichloroacetyl chloride, and then it is condensed into a liquid state by the cooling component in the condensation plate, thereby realizing the extraction of dichloroacetyl chloride.

[0004] However, in the subsequent use process, we found that after the adsorption stage is completed, when the clear liquid of dichloroacetyl chloride is introduced into the displacement device, there will also be residues in the activated carbon used as the adsorption medium. If directly discharged, it will not only cause waste of the residues, but also the dichloroacetyl chloride in them contacts the air, and the generated fumes will cause harm to the human body.

[0037] An electric telescopic rod 28 is fixedly installed at the bottom of the second rotating wheel 27, a connecting rod 29 is fixedly installed on the output shaft of the electric telescopic rod 28, a first mounting member 210 is fixedly installed at the bottom of the connecting rod 29, the first mounting member 210 is located inside the purification cylinder 21, a driving arm 211 is movably installed at the bottom of the first mounting member 210, a driven arm 212 is movably installed at the bottom of the driving arm 211, a second mounting member 213 is fixedly installed at the bottom of the driven arm 212, a fixing rod 214 is movably installed on the outer surface of the second mounting member 213, and one end of the fixing rod 214 away from the second mounting member 213 is fixedly installed on the inner wall of the purification cylinder 21;

[0038] A discharge door 216 is installed at the bottom of the purification cylinder 21, and a valve 217 is fixedly installed at the bottom of the filtrate element 2;

[0039] A heating component is provided on the turning frame 13, and the heating component is used to improve the purification efficiency;

[0040] The heating assembly includes a fixed frame 3 which is fixedly installed at the bottom of the flipping frame 13. The number of the fixed frames 3 is two, and they are respectively located on both sides of the bottom of the flipping frame 13. Support columns 31 are fixedly installed on the inner sides of both the fixed frame 3 and the flipping frame 13;

[0041] A limiting block 32 is fixedly installed at one end of the support column 31 away from the fixed frame 3 and the flipping frame 13. A limiting spring 33 is sleeved on the outer surface of the support column 31. A displacement sleeve 34 is movably installed on the outer surface of the support column 31. A displacement groove 35 adapted to the limiting block 32 is formed inside the displacement sleeve 34;

[0042] A heating sleeve 36 is sleeved on the outer surface of the filtrate member 2. The heating sleeve 36 is located between the displacement sleeves 34 on the upper and lower sides and is in movable contact with the displacement sleeves 34. A power supply 37 is fixedly installed on one side of the fixed frame 3. The power supply 37 is electrically connected to the heating sleeve 36;

[0043] The diameter of the limiting block 32 is larger than that of the support column 31. One ends of the upper and lower limiting springs 33 are fixedly connected to the displacement sleeve 34. The other end of the lower limiting spring 33 is fixedly connected to the surface of the fixed frame 3. The other end of the upper limiting spring 33 is fixedly connected to the flipping frame 13.

[0044] Specifically, during use, first, the user needs to start the servo motor 12 to drive the flipping frame 13 to rotate, so that the discharge door 216 faces upward. Then, the discharge door 216 is opened, and crude dichloroacetyl chloride and activated carbon are added into the inner cavity of the purification cylinder 21. Then, the discharge door 216 is closed and sealed;

[0045] After sealing, the power supply 37 needs to be turned on to energize the heating sleeve 36, so that the heating sleeve 36 heats the filtrate member 2 and keeps the temperature between 70 and 80 degrees Celsius. Then, starting the servo motor 12 can make the flipping frame 13 rotate, so that the purification cylinder 21 flips. At this time, the crude dichloroacetyl chloride in the inner cavity of the purification cylinder 21 will flow up and down with the flipping of the purification cylinder 21. On the one hand, it can make the activated carbon more evenly distributed. On the other hand, it can make the crude dichloroacetyl chloride be heated more evenly, improving the adsorption efficiency of the activated carbon;

[0046] Further, when the fixed frame 3 rotates, the second bevel gear 23 rotates around the surface of the first bevel gear 22. Under the action of the first bevel gear 22, the second bevel gear 23 will rotate. The second bevel gear 23 can drive the first runner 25 to rotate, so that the first runner 25 drives the transmission belt 26, and the transmission belt 26 drives the second runner 27 to rotate. The second runner 27 can drive the electric telescopic rod 28 to rotate, so that the electric telescopic rod 28 drives the connecting rod 29 to rotate. The connecting rod 29 can drive the first mounting member 210 to rotate, so that the driving arm 211 and the driven arm 212 rotate, and cooperate with the stirring member 215 to stir the crude dichloroacetyl chloride, making the crude dichloroacetyl chloride heat more evenly, improving the fluidity of the activated carbon, making its distribution more uniform, and further improving its adsorption efficiency;

[0047] Furthermore, when the filtrate member 2 flips, under the action of its own gravity and the centrifugal force generated during the flipping process, the heating sleeve 36 will move up and down reciprocally on the surface of the filtrate member 2. And under the limitation of the displacement sleeve 34 and the limiting spring 33, it can evenly heat the surface of the filtrate member 2. Compared with the traditional local heating, the present invention can further make the crude dichloroacetyl chloride heat evenly.

[0048] Example 2: Please refer to Figure 5 、 Figure 7 and Figure 8 On the displacement sleeve 34, a counter-flushing component is provided. The counter-flushing component includes a power rod 4. The power rod 4 is fixedly installed on the surface of the upper displacement sleeve 34. A counter-flushing member 41 is fixedly installed at the bottom of the power rod 4. The counter-flushing member 41 is inside the filtrate member 2, and a counter-flushing hole 42 is opened inside the counter-flushing member 41;

[0049] The connecting rod 29 is movably installed between the purification cylinder 21. The power rod 4 is in movable contact with the filtrate member 2. Rubber sealing rings are provided at the movable connection between the connecting rod 29 and the purification cylinder 21 and at the movable connection between the power rod 4 and the filtrate member 2;

[0050] The counter-flushing holes 42 distributed in the first half and the second half of the counter-flushing member 41 are arranged in a one-hundred-and-eighty-degree inversion with each other. The shape of the counter-flushing hole 42 is conical;

[0051] The shape of the counter-flushing member 41 is an arc shape adapted to the inner cavity of the filtrate member 2. The width of the counter-flushing member 41 is equal to the distance between the filtrate member 2 and the purification cylinder 21.

[0052] On the basis of Embodiment 1, when the heating sleeve 36 moves reciprocally up and down on the surface of the filtrate member 2 under the action of its own gravity and the centrifugal force generated by the flipping of the filtrate member 2, it will squeeze the displacement sleeve 34, so that the displacement sleeve 34 squeezes the limit spring 33, causing the limit spring 33 to deform. At this time, the upper displacement sleeve 34 will displace and, under the elastic force provided by the limit spring 33, will also move reciprocally up and down, so that the power rod 4 moves reciprocally up and down. The power rod 4 can be used to drive the counter-punching member 41 to move reciprocally;

[0053] When the filtrate member 2 flips, the crude dichloroacetyl chloride inside it will continuously flow and enter the filtrate member 2 from the purification cylinder 21 through the filter tank 218. At this time, during the reciprocating movement of the counter-punching member 41, it will squeeze the crude dichloroacetyl chloride, so that the crude dichloroacetyl chloride flows from the filtrate member 2 into the purification cylinder 21, and then the two parts of the crude dichloroacetyl chloride are counter-punched, further improving the fluidity of the crude dichloroacetyl chloride and making it heat more evenly;

[0054] During the reciprocating movement of the counter-punching member 41, it will squeeze the crude dichloroacetyl chloride. During the squeezing process, under the action of pressure, the crude dichloroacetyl chloride will overflow from the counter-punching holes 42. And due to the conical design of the counter-punching holes 42, when the crude dichloroacetyl chloride overflows, the flow rate is faster, generating an impact effect. And during the reciprocating movement of the counter-punching member 41, the crude dichloroacetyl chloride continuously impacts the liquid at other positions up and down, further improving the fluidity of the crude dichloroacetyl chloride, and thus driving the fluidity of the activated carbon to increase accordingly, enhancing its adsorption performance;

[0055] It should be noted that during the manufacturing of this equipment, the sealing performance is very important for this equipment. Among them, the connection between the filtrate member 2 and the purification cylinder 21 and the switch of the discharge door 216 need to be sealed to ensure that the crude dichloroacetyl chloride does not flow out.

[0056] Embodiment 3: Please refer to Figure 5 and Figure 6 , a vibration assembly is provided on the driving arm 211. The vibration assembly includes a vibrating member 5. The vibrating member 5 is fixedly installed on the lower side of the driving arm 211, and the width of the vibrating member 5 is greater than the width of the filter tank 218;

[0057] A vacuum cleaner 51 is fixedly installed on the surface of the flipping frame 13. The vacuum cleaner 51 is on one side of the valve 217. A heating box 52 is fixedly installed on the mounting frame 1. The heating box 52 is directly below the purification cylinder 21. A diversion pipe 53 is fixedly connected to the back of the heating box 52. One end of the diversion pipe 53 away from the heating box 52 is fixedly connected to the extraction device 16.

[0058] Based on Embodiment 2, when the adsorption process is completed, it is necessary to wait for the crude dichloroacetyl chloride to cool. After the cooling is completed, connect the valve 217 through a conduit, open the valve 217, turn on the vacuum cleaner 51 to adsorb the flue gas generated by the contact of dichloroacetyl chloride with air, and then introduce the clear liquid of dichloroacetyl chloride inside the filtrate part 2 and the purification cylinder 21 into the reflux device 14;

[0059] After the introduction is completed, it is necessary to close the valve 217 again and start the servo motor 12 again to make the filtrate part 2 turn over, so that the activated carbon inside the purification cylinder 21 collides with the inner wall of the purification cylinder 21 to shake off the residual liquid on its surface. At the same time, the centrifugal force generated by the turnover can be used to make the residual liquid on the surface of the purification cylinder 21 fall off, avoiding the problem of residual liquid waste;

[0060] Furthermore, after the turnover returns, it is necessary to start the electric telescopic rod 28 to drive the connecting rod 29 to descend, so that the connecting rod 29 drives the driving arm 211, thereby expanding the driving arm 211, and then making the vibrating part 5 contact the inner wall of the purification cylinder 21, causing the inner wall of the purification cylinder 21 to vibrate. On the one hand, it can further make the residual liquid adhering to the surfaces of the purification cylinder 21 and the filtrate part 2 fall off. On the other hand, it can prevent the activated carbon from staying on the inner walls of the filtrate part 2 and the purification cylinder 21 due to the retention of residual liquid. The vibration process can be realized by reciprocally starting the electric telescopic rod 28;

[0061] After the vibration operation is completed, it is necessary to connect the conduit again, open the valve 217 to introduce the residual liquid into the reflux device 14, make the clear liquid of dichloroacetyl chloride stand in the reflux device 14, then remove the precipitate, and enter the replacement stage. After the replacement stage is completed, rectification can be carried out;

[0062] At this time, the used activated carbon remains inside the purification cylinder 21. It is necessary to open the discharge door 216 and introduce the activated carbon into the heating box 52 for heating to evaporate and vaporize the residual liquid of dichloroacetyl chloride on its surface, and enter the extraction device 16 through the diversion pipe 53 for extraction, which can effectively avoid the harm caused by the discharge of dichloroacetyl chloride with the activated carbon.

[0063] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
