[0002] A distillation tower is a device that utilizes the different volatilities of the components in a mixture, that is, the different vapor pressures of the components at the same temperature, to transfer the light components in the liquid phase to the gas phase, and the heavy components in the gas phase to the liquid phase, thereby achieving the purpose of separation.

[0003] The tray structure in the existing distillation tower is mostly a tray with filter holes. When in use, the gas phase transfer is achieved by placing the mixture directly on the tray. When the feed amount is small, it is necessary to replace the small tower or manually disassemble the tray to block some of the holes on the tray to avoid excessive leakage and failure to form a liquid level on the tray, which ultimately leads to failure of the gas phase transfer.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1:

[0024] Reference Figure 1 and Figure 3 As shown, the utility model provides a technical solution for a distillation tower tray structure:

[0025] A distillation tower tray structure comprises a plurality of upper trays 3 and lower trays 4 arranged in a tower body 1, and a central shaft 2 rotatably connected to the top of the tower body 1, wherein the upper tray 3 is provided with a first filter hole 301, and the lower tray 4 is provided with a second filter hole 401, a side ring block 403 is fixedly connected to the bottom surface of the tower body 1 located at the lower tray 4, and the lower tray 4 is placed on the side ring block 403, a first annular opening 302 is provided at the center of the upper tray 3, and a second annular opening 402 is provided at the center of the lower tray 4, and a plurality of annular embedding grooves 201 are provided on the central shaft 2, the upper tray 3 is located at the first annular opening 302 and is fixedly connected to the upper part of the central shaft 2 near the annular embedding groove 201, and the central shaft 2 is located at the annular embedding groove 201 and passes through the second annular opening 402.

[0026] Among them, it should be supplemented that the first filter holes 301 are arranged at equal distances along the radial direction of the upper tower plate 3 and then at equal distances around the center of the upper tower plate 3, the second filter holes 401 are arranged at equal distances along the radial direction of the lower tower plate 4 and then at equal distances around the center of the lower tower plate 4, the inner diameters of the first filter holes 301 and the second filter holes 401 are the same, the first filter holes 301 and the second filter holes 401 can be completely overlapped after the upper tower plate 3 rotates, a gap is set between the upper tower plate 3 and the lower tower plate 4, and the central axis 2 is located at the annular embedding groove 201 and does not contact the second annular opening 402 opened on the lower tower plate 4.

[0027] Working principle: when it is necessary to adjust the through hole on the tower plate, in this structure, it is only necessary to fix the central shaft 2 at one end of the top of the tower body 1 through the motor, reduction gear set, etc. in the prior art. It should be noted that the motor and the reduction gear set are both prior art and will not be described in detail here. Start the motor, and the central shaft 2 rotates slowly through the transmission of the reduction gear set, thereby driving the upper tower plate 3 to start rotating. Since there is a gap between the upper tower plate 3 and the lower tower plate 4, and the lower tower plate 4 is placed on the side ring block 403, the upper tower plate 3 and the lower tower plate 4 rotate relative to each other. Figure 3 As shown, the first filter hole 301 and the second filter hole 401 are staggered, so that the overlapping area of ​​the first filter hole 301 and the second filter hole 401 on the entire tray formed by the upper tray 3 and the lower tray 4 gradually becomes smaller.

[0028] Through the above-mentioned arrangement, the size of the through holes on the tower plate can be adjusted quickly and automatically. The farther the through hole size is from the center of the upper tower plate 3 or the lower tower plate 4, the faster the change of the size of the through hole is with the rotation of the central axis 2. The raw materials that need to be precisely controlled in amount can be placed on the top surface of the upper tower plate 3 close to its center, which greatly improves the adaptability of the present structure.

[0029] Embodiment 2:

[0030] A cleaning assembly is disposed on the top of the upper tray 3 , and an alignment assembly is disposed in the gap between the second annular opening 402 and the annular embedding groove 201 .

[0031] Furthermore, the cleaning component includes a cleaning block 5 fixedly connected to the side wall of the tower body 1, an inner cavity 503 is arranged inside the cleaning block 5, a plurality of sliding grooves 504 are opened at the bottom of the inner cavity 503, the sliding grooves 504 are arranged equidistantly along the radial direction of the upper tower plate 3 or the lower tower plate 4, the sliding grooves 504 can be placed directly above the first filter holes 301 arranged radially along the upper tower plate 3 through the rotation of the upper tower plate 3, a driving rod 501 is slidably connected to the top of the inner cavity 503, a cleaning guide rod 505 is slidably connected inside the sliding groove 504, the inner cavity 503 and the cleaning guide rod 505 are connected by a connecting rod 502, one end of the driving rod 501 extends out of the cleaning block 5 and the tower body 1, and a telescopic component is fixedly connected to the outer wall of the tower body 1 near the driving rod 501, which is used to control the driving rod 501 to make a reciprocating motion at the top of the inner cavity 503.

[0032] Furthermore, the alignment assembly includes a ratchet 6 fixedly connected in the second annular opening 402 , a pawl 601 is hingedly connected to the outer wall of the central axis 2 located at the annular embedding groove 201 , and a spring 602 is fixedly connected between the pawl 601 and the outer wall of the central axis 2 located at the annular embedding groove 201 .

[0033] Among them, it should be additionally explained that the telescopic assembly is configured as a cylinder 506. When the ratchet block and the pawl 601 on the ratchet wheel 6 are stuck, the second filter hole 401 and the first filter hole 301 overlap, and the cleaning guide rod 505 can be extended into the first filter hole 301 and the second filter hole 401 under the action of the connecting rod 502, and the bottom surface of the cleaning block 5 is in contact with the top surface of the upper tower plate 3.

[0034] Working principle: when it is necessary to clean the top surface of the upper tower plate 3 and the first filter hole 301 and the second filter hole 401, it is only necessary to start the motor to drive the central shaft 2 to start rotating. Since the pawl 601 and the ratchet teeth on the ratchet 6 are stuck, this process is a prior art and will not be described in detail here. In Example 1, the rotation direction of the central shaft 2 is opposite to that at this time, and the pawl 601 and the ratchet teeth on the ratchet 6 will not be stuck, so that the upper tower plate 3 and the lower tower plate 4 will rotate synchronously. At this time, the second filter hole 401 and the first filter hole 301 overlap. When the first filter hole 301 runs to the bottom of the sliding groove 504, the cylinder 506 is started to make the drive rod 501 telescopic movement. Under the action of the connecting rod 502, the cleaning guide rod 505 is pushed into the first filter hole 301 and the second filter hole 401.

[0035] Through the above-mentioned settings, the first filter hole 301 and the second filter hole 401 are successfully cleaned. It should be noted that the frequency of the telescopic movement of the drive rod 501 driven by the cylinder 506 and the speed of the central axis 2 driven by the motor can be adjusted through settings, so that each time the cleaning guide rod 505 cleans the first filter hole 301 and the second filter hole 401, the first filter hole 301 and the second filter hole 401 are placed directly below the sliding groove 504. At the same time, due to the contact between the cleaning block 5 and the top surface of the upper tower plate 3, the material remaining on the top surface of the upper tower plate 3 is successfully scraped off. The structural setting is simple, efficient, and highly automated, which greatly improves the utilization efficiency of the tower body 1.

[0036] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
