At present, distillation towers are usually used for operation. Distillation towers are equipped with trays. The trays are the core components of the tray tower. Their function is to keep the gas and liquid phases in full contact so that they can carry out mass transfer and heat transfer under good conditions. There are two types of gas-liquid two-phase flow modes on the trays: cross flow and counter flow.

[0003] After searching, for example, a patent with announcement number CN206499896U discloses a tower plate (1) of a distillation device, wherein an overflow weir (11) is arranged at the edge of the tower plate (1), a plurality of liquid holes (12) are opened on the tower plate, and the opening rate of the tower plate (1) is 10-25%. The utility model also discloses a distillation device, wherein the tower plate in the distillation device is the above-mentioned tower plate. The tower plate of the distillation device provided by the utility model and the distillation device including the tower plate have the advantages of high separation capacity, effective inhibition of polymerization on the tower plate surface during the distillation process, effective improvement of the problem of easy clogging of the tower plate, saving the maintenance cost of the distillation device during operation, good economy, etc.

[0004] The trays in the above patents currently still have the following deficiencies:

[0005] During use, the current tower plates can usually only reach the next layer by pushing the valve through the pressure of gas or liquid. However, the pressure of the valve is fixed, which makes it difficult to adjust the resistance. Different pressures cannot be adjusted according to different production needs, and different production needs cannot be met, which has certain limitations. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a tower plate structure for a benzyltoluene continuous distillation device to solve the problem raised in the above background technology that during use, the current tower plate can usually only push the valve to reach the next layer through the pressure of gas or liquid, but the pressure of the valve is fixed, resulting in the resistance being difficult to adjust, and different pressures cannot be adjusted according to different production needs, and different production needs cannot be met, which has certain limitations.

[0007] The purpose and effect of the tray structure for a benzyltoluene continuous distillation device of the utility model are achieved by the following specific technical means:

[0008] A tower plate structure for a benzyltoluene continuous distillation device comprises: a plate body; the plate body is a circular plate structure, and the top of the plate body is equidistantly arranged with penetrating circular through groove structures; a fixing rod with a cylindrical structure is fixedly arranged in the middle of the top of the plate body, and a threaded groove structure is arranged on the outer side of the fixing rod, and a spring is sleeved on the outer side of the fixing rod; a connecting ring with a circular ring structure is slidably arranged on the outer side of the fixing rod; and a bolt is rotatably arranged on the outer side of the fixing rod through threaded cooperation.

[0009] Furthermore, a group of baffles with rectangular plate structures are fixedly arranged on both sides of the top of the plate body; a reflux channel with a semicircular through groove structure is opened on one side of the top of the plate body; a sliding filter cover with a circular ring structure is slidably arranged in the circular through groove of the plate body, and a through-type filter hole structure is opened in a circular array on the outer side of the sliding filter cover; a top plate with a circular plate structure is fixedly arranged on the top of the sliding filter cover; a connecting rod with an L-shaped rod structure is fixedly arranged on the top of the top plate, and the connecting rod is fixedly connected to the connecting ring.

[0010] Furthermore, a rotating shaft is rotatably arranged at the bottom of the top plate, and the rotating shaft adopts a T-shaped rod structure; fan blades are fixedly arranged on the outside of the rotating shaft; a group of scrapers are fixedly arranged on both sides of the bottom end of the rotating shaft, and the scrapers adopt a wedge block structure, and the outer ends of the scrapers are in contact with the inner wall of the sliding filter cover.

[0011] Furthermore, a group of side rods of an L-shaped rod structure are fixedly arranged on both sides of the top of the connecting ring; and a counterweight block of a circular ring structure is slidably arranged on the outer side of the side rods.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] During operation, the difficulty of sliding the connecting ring upward can be adjusted by rotating the bolt to apply pressure to the spring, thereby applying pressure to the connecting ring through the spring, or stacking counterweights on the side rods to increase the weight of the connecting ring. This can simultaneously adjust the sliding resistance of each group of sliding filter covers, thereby achieving the purpose of adjusting the pressure of the medium passing through the filter. Adjustments can be made according to different production needs, which greatly improves the practicability of the device and meets different production needs.

[0014] In the process of the medium seeping through the sliding filter cover, the fan blades on the inner side of the sliding filter cover can be driven to rotate synchronously, thereby driving the two sets of scrapers to rotate on the inner side of the sliding filter cover and cleaning the inner wall of the sliding filter cover to avoid the medium being retained on the inner wall of the sliding filter cover and causing the filter holes to be blocked, thereby maintaining the passing performance of the sliding filter cover and helping to maintain production efficiency.

[0024] Embodiment 1:

[0025] As attached Figure 1 To Attachment Figure 5 As shown:

[0026] The utility model provides a tower plate structure for a benzyltoluene continuous distillation device, comprising: a plate body 1; the plate body 1 adopts a circular plate structure, and the top of the plate body 1 is equidistantly arranged with a penetrating circular through groove structure; a fixing rod 108 with a cylindrical structure is fixedly arranged in the middle of the top of the plate body 1, and a threaded groove structure is opened on the outer side of the fixing rod 108, and a spring is sleeved on the outer side of the fixing rod 108; a connecting ring 109 with a circular ring structure is slidably arranged on the outer side of the fixing rod 108; a bolt 110 is rotatably arranged on the outer side of the fixing rod 108 through threaded matching.

[0027] Among them, a group of baffles 101 with a rectangular plate structure are fixedly arranged on both sides of the top of the plate body 1; a reflux channel 102 with a semicircular through groove structure is opened on one side of the top of the plate body 1; a sliding filter cover 103 with a circular ring structure is slidably arranged in the circular through groove of the plate body 1, and a through-type filter hole structure is opened in a circular array on the outer side of the sliding filter cover 103; a top plate 104 with a circular plate structure is fixedly arranged on the top of the sliding filter cover 103; a connecting rod 105 with an L-shaped rod structure is fixedly arranged on the top of the top plate 104, and the connecting rod 105 is fixedly connected to the connecting ring 109.

[0028] A group of side rods 111 of an L-shaped rod structure are fixedly arranged on both sides of the top of the connecting ring 109 ; and a counterweight block 112 of a circular ring structure is slidably arranged on the outer side of the side rods 111 .

[0029] The specific usage and function of this embodiment are as follows:

[0030] When in use, the medium at the bottom of the plate body 1 enters the interior of the sliding filter cover 103, and the pressure generated by the medium pushes the top plate 104 and the sliding filter cover 103 to slide upward along the circular through groove on the plate body 1, so that the filter holes on the sliding filter cover 103 leak out, thereby completing the filtering process for the medium, so that the medium can enter the next layer of the plate body 1 for further processing. During the filtering process, if it is necessary to increase the sliding resistance of the sliding filter cover 103 and the top plate 104, that is, the medium below needs to use a greater pressure to complete the filtering, the spring on the outside of the fixing rod 108 can be compressed by rotating the bolt 110 to increase the pressure of the spring, so that the pressure of the spring can be increased, so that Pressure is applied to the connecting ring 109. When the pressure of the connecting ring 109 increases, pressure can be applied to each group of sliding filter covers 103 and top plate 104 synchronously through each group of connecting rods 105, thereby increasing the difficulty of the sliding filter covers 103 and top plate 104 to rise upward, increasing the pressure and the osmotic pressure of the medium, meeting different production needs, and greatly improving the practicality of the device; at the same time, the weight of the connecting ring 109 can be increased by installing a counterweight block 112 on the two groups of side rods 111, which can also increase the difficulty of lifting the sliding filter covers 103 and top plate 104. Different methods can be used for adjustment according to actual conditions, further improving the functionality of the device.
