Description

Technical Field

[0001] This utility model belongs to the technical field of downcomer distributors, specifically a suspended downcomer distributor. Background Technology

[0002] The downcomer is a component that allows liquid to flow from the upper tray to the lower tray. It is also a part where gas and liquid are separated. The design of the downcomer allows the liquid to have a certain residence time between the trays to ensure that the gas and liquid phases form sufficient interphase mass transfer surface on the trays, thereby improving mass transfer efficiency. The downcomer distributor is responsible for distributing the liquid between the trays.

[0003] The existing downcomer distributor cannot adjust the volume of liquid stored inside the distribution tank as needed when injecting liquid into it, nor can it promptly discharge excess liquid. Therefore, improvements are needed. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a suspended downcomer distributor, which solves the problem that existing downcomer distributors cannot arbitrarily adjust the liquid storage capacity inside the distribution box as needed when injecting liquid into it.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a suspended downcomer distributor, comprising a distribution box, wherein two sets of curved air pipes and three sets of curved liquid pipes are staggered and fixedly installed at the bottom of the distribution box, the top surface of the curved liquid pipes is provided with multiple sets of liquid guiding holes, a fixing frame is fixedly installed at the center of the inner wall of the curved liquid pipes, and a rotating stud is rotatably installed between the fixing frame and the top of the inner wall of the curved liquid pipes, a driven bevel gear is fixedly installed at the top of the rotating stud through the top of the curved liquid pipes, four sets of limiting slide rods are fixedly installed at equal angles between the fixing frame and the top of the inner wall of the curved liquid pipes, and movable screw sleeves are slidably installed on the surfaces of the rotating stud and the four sets of limiting slide rods.

[0006] As a further embodiment of this utility model: a base frame is fixedly installed at the bottom of the distribution box, and five sets of mounting holes are equidistantly provided at the bottom of the distribution box. The bottoms of the curved air pipe and the curved liquid pipe extend through the mounting holes into the interior of the base frame.

[0007] As a further embodiment of this utility model: a rotating motor is fixedly installed on the top of one side of the distribution box, a drive bevel gear is fixedly installed at the output end of the rotating motor, a linkage shaft is rotatably installed between the top of the inner side of the distribution box, and a transmission bevel gear is fixedly installed at the end of the linkage shaft near the rotating motor through the distribution box, and the drive bevel gear and the transmission bevel gear mesh with each other.

[0008] As a further embodiment of this utility model: three sets of driven bevel gears are fixedly installed at equal intervals on the surface of the transmission bevel gear inside the distribution box, and the driven bevel gears one and two are positioned corresponding to each other and mesh with each other.

[0009] As a further embodiment of this utility model: a baffle plate is fixedly installed on the top of the distribution box on one side of the linkage shaft, and the bottom of the baffle plate is higher than the top of the curved air pipe and the three sets of curved liquid pipes. The inner wall of the distribution box is inclined on the side of the baffle plate away from the linkage shaft. A breathable mesh plate is fixedly installed inside the distribution box on the top of the linkage shaft.

[0010] As a further embodiment of this utility model: four sets of support frames are fixedly installed at equal angles on the surface of the movable screw sleeve, and a sleeve is fixedly installed between the surfaces of the four sets of support frames away from the movable screw sleeve, and an elastic sealing sleeve is fixedly installed on the surface of the sleeve.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This suspended downcomer distributor, through the setting of a curved liquid pipe, a rotating stud, a movable screw sleeve, and an elastic sealing sleeve, starts a rotating motor to control the linkage shaft to drive three sets of driven bevel gears to rotate synchronously, which in turn drives the rotating stud to rotate synchronously. This controls the three sets of movable screw sleeves to drive the elastic sealing sleeve to rise and fall synchronously on the inner wall of the curved liquid pipe. The height of the elastic sealing sleeve inside the curved liquid pipe can be controlled according to production needs, and the number of times the elastic sealing sleeve seals the liquid guide hole can be adjusted. This facilitates the timely discharge of liquid from the liquid guide hole on the surface of the curved liquid pipe after the liquid inside the distribution box has accumulated to a certain height.

[0013] 2. This suspended downcomer distributor, by setting up a distribution box, a baffle plate, and a venting mesh plate, ensures that when liquid is poured into the distribution box from its inclined surface, the splashed liquid falls on the surface of the baffle plate away from the curved air pipe, preventing the liquid from splashing up and falling onto the top of the curved air pipe and flowing out from it. When gas enters the distribution box from the curved air pipe, the gas accumulates on the top surface of the liquid inside the distribution box located on the side of the baffle plate and gradually disperses through the venting mesh plate, preventing gas from accumulating on the top surface of the liquid inside the distribution box and affecting the liquid pouring into the distribution box.

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] like Figure 1-4 As shown, this utility model provides a technical solution: a suspended downcomer distributor, including a distribution box 1, a base frame 2 fixedly installed at the bottom of the distribution box 1, five sets of mounting holes 3 equidistantly provided at the bottom of the distribution box 1, the bottom of the curved air pipe 11 and the curved liquid pipe 12 extending through the mounting holes 3 into the interior of the base frame 2. By providing the base frame 2, the curved air pipe 11 and the curved liquid pipe 12 are located inside the base frame 2, thus avoiding damage to the curved air pipe 11 and the curved liquid pipe 12 when the distribution box 1 is placed on the ground.

[0021] A rotary motor 4 is fixedly installed on the top of one side of the distribution box 1. A drive bevel gear 5 is fixedly installed at the output end of the rotary motor 4. A linkage shaft 6 is rotatably installed between the top of the inner side of the distribution box 1. A transmission bevel gear 7 is fixedly installed through the distribution box 1 at the end of the linkage shaft 6 near the rotary motor 4. The drive bevel gear 5 and the transmission bevel gear 7 mesh with each other. Because there is a rotary motor 4 and a linkage shaft 6, the rotary motor 4 is started to rotate. Under the meshing action of the drive bevel gear 5 and the transmission bevel gear 7, the linkage shaft 6 is controlled to rotate, thereby driving the three sets of driven bevel gears 8 to rotate synchronously.

[0022] The transmission bevel gear 7 is located inside the distribution box 1 and three sets of driven bevel gears 8 are fixedly installed at equal intervals. The driven bevel gears 8 and 16 are corresponding to each other and mesh with each other. By providing driven bevel gears 8 and 16, when the linkage shaft 6 controls the three sets of driven bevel gears 8 to rotate synchronously, the three sets of driven bevel gears 16 can drive the corresponding rotating studs 15 to rotate synchronously.

[0023] A baffle plate 9 is fixedly installed on one side of the linkage shaft 6 inside the distribution box 1. The bottom of the baffle plate 9 is higher than the top of the curved air pipe 11 and the three sets of curved liquid pipes 12. Because of the baffle plate 9, when liquid is poured into the distribution box 1, the liquid will splash up inside the distribution box 1 and splash onto the surface of the baffle plate 9, thereby preventing the liquid from splashing onto the top of the curved air pipe 11.

[0024] The inner wall of the distribution box 1 is inclined on the side of the baffle plate 9 away from the linkage shaft 6. A ventilated mesh plate 10 is fixedly installed inside the distribution box 1 at the top of the linkage shaft 6. With the ventilated mesh plate 10, the gas entering the distribution box 1 from the curved air pipe 11 is released through the ventilated mesh plate 10, which prevents the gas from accumulating on the top of the liquid inside the distribution box 1, thus avoiding excessive gas pressure inside the distribution box 1.

[0025] Two sets of curved air pipes 11 and three sets of curved liquid pipes 12 are fixedly installed at the bottom of the distribution box 1. The top surface of the curved liquid pipe 12 is provided with multiple sets of liquid guiding holes 13. A fixing frame 14 is fixedly installed at the center of the inner wall of the curved liquid pipe 12. A rotating stud 15 is rotatably installed between the fixing frame 14 and the top of the inner wall of the curved liquid pipe 12. The top of the rotating stud 15 passes through the top of the curved liquid pipe 12 and is fixedly installed with a driven bevel gear 16. Because of the rotating stud 15, under the meshing action of the driven bevel gear 16 and the driven bevel gear 8, the rotating stud 15 is controlled to rotate inside the curved liquid pipe 12, thereby adjusting the height of the moving screw sleeve 18 inside the curved liquid pipe 12 and controlling the sequential closing or opening of the liquid guiding holes 13 at different heights on the surface of the curved liquid pipe 12.

[0026] Four sets of limiting slide rods 17 are fixedly installed at equal angles between the fixed frame 14 and the top of the curved liquid tube 12. A movable screw sleeve 18 is slidably installed on the surface of the rotating stud 15 and the four sets of limiting slide rods 17. By setting the limiting slide rods 17, when the movable screw sleeve 18 moves up and down inside the curved liquid tube 12, the movable screw sleeve 18 slides on the surface of the limiting slide rods 17, ensuring that the movable screw sleeve 18 does not rotate synchronously with the rotating stud 15 when moving up and down.

[0027] Four sets of support frames 19 are fixedly installed at equal angles on the surface of the movable screw sleeve 18. A sleeve 20 is fixedly installed between the surfaces of the four sets of support frames 19 away from the movable screw sleeve 18. Because of the sleeve 20, when the movable screw sleeve 18 moves inside the curved liquid tube 12, the sleeve 20 presses the elastic sealing sleeve 21 against the inner wall of the curved liquid tube 12 to clamp and seal the liquid guide hole 13.

[0028] An elastic sealing sleeve 21 is fixedly installed on the surface of the sleeve 20. Because of the elastic sealing sleeve 21, when the moving screw sleeve 18 drives the elastic sealing sleeve 21 to rise and fall inside the curved liquid pipe 12, the elastic sealing sleeve 21 is squeezed and deformed on one side of the liquid guide hole 13, thereby sealing and closing the liquid guide hole 13, ensuring that the liquid inside the distribution box 1 will not flow into the curved liquid pipe 12 from the liquid guide hole 13.

[0029] The working principle of this utility model is as follows:

[0030] After connecting the curved gas pipe 11 and curved liquid pipe 12 to the distillation column, pour an appropriate amount of liquid into the distribution box 1. The poured liquid splashes onto the surface of the baffle plate 9 to prevent the splashed liquid from falling directly into the curved gas pipe 11 and affecting the high-temperature gas inside the distillation column from entering the distribution box 1 through the curved gas pipe 11. At the same time, the high-temperature gas inside the distillation column enters the distribution box 1 through the curved gas pipe 11 and dissipates from the permeable mesh plate 10. Start the rotating motor 4 to control the three sets of driven bevel gears 8 on the surface of the linkage shaft 6 to rotate synchronously, driving the three sets of rotating studs 15 to rotate synchronously. Control the three sets of moving screw sleeves 18 to move up and down synchronously on the surface of the rotating studs 15, so that the liquid guide hole 13 on the surface of the curved liquid pipe 12 opens from top to bottom. When the liquid level inside the distribution box 1 reaches the opened liquid guide hole 13, the liquid inside the distribution box 1 flows evenly from the liquid guide hole 13 into the three sets of curved liquid pipes 12 and is discharged.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
