Description

Technical Field

[0001] This utility model relates to the field of distillation columns, and in particular to a vacuum distillation column. Background Technology

[0002] A vacuum distillation column is a device commonly used to separate high-boiling-point liquids. It achieves the separation of components by distilling under reduced pressure conditions. It is carried out in an environment below atmospheric pressure, so the separation can be performed at a lower temperature.

[0003] When using a vacuum distillation column, liquid is fed into the column through a feed pipe. A controller activates a vacuum pump at the top of the column to reduce the pressure inside, thereby lowering the liquid's boiling point. An internal heating element then heats the liquid, causing it to evaporate into steam. As the steam rises, it comes into contact with the cooling liquid in the condenser, condensing the lighter components and achieving liquid-liquid separation. However, impurities in the liquid enter the column along with the feed pipe. These impurities are not completely evaporated or separated; some accumulate on the inner wall of the column or the feed pipe. This accumulation or adhesion increases the fluid flow resistance within the column and feed pipe, affecting the normal flow of the liquid and the distillation process, thus impacting the effectiveness of the vacuum distillation column. Utility Model Content

[0004] The technical problem this invention aims to solve is that when liquid enters the feed pipe, impurities in the liquid will also reach the inside of the tower. These impurities will not be completely evaporated or separated, and some impurities will be deposited on the inner wall of the tower or the inner wall of the feed pipe. The accumulation or adhesion of these impurities to the inner wall of the equipment will increase the fluid flow resistance in the tower and the feed pipe, affecting the normal flow of the liquid and the distillation process, thereby causing problems that affect the performance of the vacuum distillation tower.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a vacuum distillation column, including a column body, a feed pipe at the upper end of the column body, a connecting pipe on one side of the column body, a condenser on one side of the connecting pipe, a vacuum pump at the upper end of the column body, a controller on one side of the column body, and a filter device at the upper end of the feed pipe. The filter device filters impurities in the liquid reaching the feed pipe through a filter screen.

[0006] Preferably, the filtration device includes a mounting block, a first bolt, a connecting plate, an electric telescopic rod, a placement block, and two filter screens. The mounting block is located at the upper end of the feed pipe, the first bolt is inserted into one side of the mounting block to fix the connecting plate, the electric telescopic rod is located on one side of the connecting plate, the placement block is located at the output end of the electric telescopic rod, and the two filter screens are located inside the placement block.

[0007] Preferably, a stabilizing plate is provided on one side of the connecting plate, and the stabilizing plate passes through the placement block to provide limiting support for the placement block.

[0008] Preferably, the placement block is provided with an auxiliary component, which includes a second bolt, a fixing block, a filter cloth, and several anti-slip blocks. The second bolt is inserted into one side of the fixing block to be threadedly fixed to the placement block. The filter cloth is placed on the side of the fixing block away from the filter screen to perform secondary filtration of the liquid. Several anti-slip blocks are arranged equidistantly around the inner wall of the fixing block to increase the friction of the fixing block.

[0009] Preferably, the inner wall of the placement block is provided with a positioning block to position the fixing block.

[0010] Preferably, the upper end of the placement block is provided with a protective device, which includes a slide rail, a sliding frame, a protective plate and a third bolt. The slide rail is located at the upper end of the placement block, and the sliding frame slides inside the slide rail to move the protective plate fixed on one side. The protective plate is located at a distance of one dimension away from the slide rail on the sliding frame. The protective plate is located at both ends of the sliding frame, and the third bolt is inserted into one side of the sliding frame to be threadedly fixed to the slide rail.

[0011] Preferably, the upper end of the sliding frame is provided with a control frame to increase the size of the upper end of the sliding frame.

[0012] Preferably, the slide rail is provided with a reinforcing rod inside, and the reinforcing rod passes through the slide frame to improve the connection strength between the slide frame and the slide rail.

[0013] In summary, the beneficial effects of this utility model are as follows:

[0014] By using a filtration device, the liquid reaching the feed pipe can be filtered. Another unused filter screen can be aligned with the feed pipe for use, and the used filter screen can be cleaned to avoid affecting the normal operation of the filtration device. This prevents impurities inside the liquid from reaching the feed pipe and the inside of the tower. Some impurities accumulate or adhere to the inner wall of the equipment, which can increase the fluid flow resistance in the tower and feed pipe, affecting the normal flow of liquid and the distillation process, thereby improving the performance of the vacuum distillation tower.

[0015] By using auxiliary components, a filter cloth can be used to perform secondary filtration of the liquid, so that even fine impurities are filtered out, thereby improving the effectiveness of the filtration device.

[0016] By using a protective device, the entrance to the placement block can be blocked and protected, preventing debris from entering the interior of the placement block when the filter is not in use, thereby improving the effectiveness of the placement block and, consequently, the effectiveness of the filter.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Figures 1 to 6The vacuum distillation column shown includes a column body 1, a feed pipe 2 at the upper end of the column body 1, a connecting pipe 3 on one side of the column body 1, a condenser 4 on one side of the connecting pipe 3, a vacuum pump 5 at the upper end of the column body 1, a controller 8 on one side of the column body 1, and a filter device 6 at the upper end of the feed pipe 2. The filter device 6 filters impurities in the liquid reaching the feed pipe 2 through a filter screen 66.

[0028] Figures 1 to 6 As shown, when using a vacuum distillation column, liquid is fed into the column body 1 through the feed pipe 2. At this time, the filter device 6 filters impurities in the liquid. Then, the vacuum pump 5 at the top of the column body 1 is started by the controller 8 to reduce the pressure inside the column body 1 and reduce the boiling point of the liquid. The liquid is then heated by the heating device inside the column body 1 to evaporate and form steam. As the steam rises, it comes into contact with the cooling liquid in the condenser 4, and the light components in the steam are condensed, thereby achieving liquid separation.

[0029] Figures 1 to 6 The filter device 6 shown includes a mounting block 61, a first bolt 62, a connecting plate 63, an electric telescopic rod 64, a placement block 65, and two filter screens 66. The mounting block 61 is located at the upper end of the feed pipe 2. The first bolt 62 is inserted into one side of the mounting block 61 to fix the connecting plate 63. The electric telescopic rod 64 is located on one side of the connecting plate 63. The placement block 65 is located at the output end of the electric telescopic rod 64. The two filter screens 66 are located inside the placement block 65.

[0030] Figures 1 to 6As shown, when using the filter device 6, the connecting plate 63 is placed inside the mounting block 61 fixed on one side of the tower body 1. Then, the first bolt 62 is rotated to insert the first bolt 62 into one side of the mounting block 61 for threaded fixation with the connecting plate 63. The electric telescopic rod 64 is activated, causing the placement block 65 fixed at the output end to move, aligning a filter screen 66 fixed on the placement block 65 with the feed pipe 2. When the liquid enters the feed pipe 2, the filter screen 66 fixed on the placement block 65 filters impurities in the liquid. The liquid then passes through the placement block 65 into the feed pipe 2, and finally into the tower body 1 for distillation. When the filter screen 66 needs to be cleaned, the electric telescopic rod 64 is activated. The telescopic rod 63 aligns an unused filter screen 66 on the placement block 65 with the feed pipe 2, allowing for the cleaning of the other filter screen 66 without affecting the normal operation of the filtration device 6. Using the filtration device 6, the liquid reaching the feed pipe 2 can be filtered, and the unused filter screen 66 can be aligned with the feed pipe 2 for use. The used filter screen 66 can then be cleaned without affecting the normal operation of the filtration device 6. This prevents impurities from entering the feed pipe 2 and the interior of the tower 1. Accumulation or adhesion of impurities to the inner wall of the equipment can increase fluid flow resistance within the tower 1 and feed pipe 2, affecting normal liquid flow and the distillation process, thus improving the efficiency of the vacuum distillation tower.

[0031] Figures 1 to 6 A stabilizing plate 68 is provided on one side of the connecting plate 63, and the stabilizing plate 68 passes through the placement block 65 to limit and support the placement block 65. The stabilizing plate 68 is fixed to the connecting plate 63 and passes through the placement block 65 to limit and support the placement block 65, thereby making the placement block 65 move and be used more stably.

[0032] Figures 1 to 6The placement block 65 shown has an auxiliary component 67 inside. The auxiliary component 67 includes a second bolt 671, a fixing block 672, a filter cloth 673, and several anti-slip blocks 675. The second bolt 671 is inserted into one side of the fixing block 672 to be threadedly fixed to the placement block 65. The filter cloth 673 is placed on the side of the fixing block 672 away from the filter screen 66 to perform secondary filtration of the liquid. Several anti-slip blocks 675 are arranged equidistantly around the inner wall of the fixing block 672 to increase the friction of the fixing block 672. When using the auxiliary component 67, the fixing block 672 with the anti-slip block 675 can be moved into the placement block 65, and then the filter cloth 673 can be brought into contact with the second bolt 671. The second bolt 671 can then be rotated to thread the second bolt 671 through the fixing block 672 and the placement block 65. Alternatively, the fixing block 672 can be fixed with the second bolt 671 first, and then the filter cloth 673 can be glued and fixed to one side of the fixing block 672. After the filter cloth 673 is fixed to one side of the fixing block 672, it is fixed in the position inside the placement block 65. When using the filter device 6, the liquid is filtered a second time through the filter cloth 673. By using the auxiliary component 67, the liquid can be filtered a second time through the filter cloth 673, so that even small impurities are filtered out, thereby improving the performance of the filter device 6.

[0033] Figures 1 to 6 The inner wall of the placement block 65 shown is provided with a positioning block 674 to position the fixing block 672. By fixing the positioning block 674 to the inner wall of the placement block 65, the mounting block 61 is quickly positioned on the inner wall of the placement block 65, which facilitates the subsequent threaded fixing of the fixing block 672 with the second bolt 671.

[0034] Figures 1 to 6The upper end of the placement block 65 shown is provided with a protective device 7. The protective device 7 includes a slide rail 71, a sliding frame 72, a protective plate 73 and a third bolt 74. The slide rail 71 is set at the upper end of the placement block 65. The sliding frame 72 slides inside the slide rail 71 to drive the protective plate 73 fixed on one side to move. The protective plate 73 is set at a distance of one dimension away from the slide rail 71. The protective plate 73 is set at both ends of the sliding frame 72. The third bolt 74 is inserted into one side of the sliding frame 72 to be threadedly fixed to the slide rail 71. When using the protective device 7, the sliding frame 72 can be moved to slide inside the slide rail 71 fixed at the upper end of the placement block 65. Then, the protective plates 73 fixed at both ends of the sliding frame 72 reach the upper end of the placement block 65 to block and protect the entrance of the placement block 65. Then, the third bolt 74 is rotated to pass through the sliding frame 72 and be threaded to one side of the slide rail 71. The position of the protective plate 73 is then fixed. By using the protective device 7, the entrance of the placement block 65 can be blocked and protected, preventing debris from entering the interior of the placement block 65 when the filter device 6 is not in use, thereby improving the performance of the placement block 65 and thus improving the performance of the filter device 6.

[0035] Figures 1 to 6 The sliding frame 72 shown has a control frame 75 at its upper end to raise the size of the upper part of the sliding frame 72. The control frame 75 is fixed to the end of the sliding frame 72, raising its upper size so that the operator can hold the control frame 75 to move the sliding frame 72, thereby improving its usability. A reinforcing rod 76 is provided inside the slide rail 71, and the reinforcing rod 76 passes through the sliding frame 72 to increase the connection strength between the sliding frame 72 and the slide rail 71. The reinforcing rod 76 is fixed inside the slide rail 71 and passes through the sliding frame 72, acting as a sliding block with the sliding frame 72, further enhancing the connection strength between the sliding frame 72 and the slide rail 71 and preventing separation of the sliding frame 72 and the slide rail 71 under force.

[0036] Working principle: When using a vacuum distillation column, liquid is fed into the column body 1 through the feed pipe 2. At this time, the filter device 6 filters impurities in the liquid. Then, the vacuum pump 5 at the top of the column body 1 is started by the controller 8 to reduce the pressure inside the column body 1 and reduce the boiling point of the liquid. The liquid is heated by the heating device inside the column body 1 to evaporate and form steam. Then, during the process of steam rising, it comes into contact with the cooling liquid in the condenser 4. The light components in the steam are condensed, thereby achieving liquid separation. When using the filter device 6, place the connecting plate 63 inside the mounting block 61 fixed on one side of the tower body 1, then rotate the first bolt 62 to insert it into the mounting block 61 and thread it onto the connecting plate 63. Start the electric telescopic rod 64 to move the placement block 65 fixed at the output end, aligning a filter screen 66 fixed on the placement block 65 with the feed pipe 2. When the liquid enters the feed pipe 2, the filter screen 66 fixed on the placement block 65 and the filter cloth 673 inside the auxiliary component 67 filter impurities in the liquid. The liquid then passes through the placement block 65 into the feed pipe 2, and finally into the tower body 1 for distillation. The filter screen 66 needs to be cleaned at certain times. When the time is right, activate the electric telescopic rod 63 to align one unused filter screen 66 of the placement block 65 with the feed pipe 2. Then, the other filter screen 66 can be cleaned without affecting the normal use of the filter device 6. By using the filter device 6, the liquid reaching the feed pipe 2 can be filtered, and the other unused filter screen 66 can be aligned with the feed pipe 2 for use. Then, the used filter screen 66 can be cleaned without affecting the normal use of the filter device 6. This prevents impurities inside the liquid from reaching the feed pipe 2 and the interior of the tower 1. Some impurities accumulate or adhere to the inner wall of the equipment, which can increase the fluid flow resistance in the tower 1 and the feed pipe 2, affecting the normal flow of the liquid and the distillation process, thereby improving the performance of the vacuum distillation tower.

[0037] When using the protective device 7, the sliding frame 72 can be moved to slide inside the slide rail 71 fixed at the upper end of the placement block 65. Then, the protective plates 73 fixed at both ends of the sliding frame 72 reach the upper end of the placement block 65 to block and protect the entrance of the placement block 65. Then, the third bolt 74 is rotated to pass through the sliding frame 72 and be threaded to one side of the slide rail 71. The position of the protective plate 73 is then fixed. By using the protective device 7, the entrance of the placement block 65 can be blocked and protected, preventing debris from entering the interior of the placement block 65 when the filter device 6 is not in use, thereby improving the performance of the placement block 65 and thus improving the performance of the filter device 6.
