Description

Technical Field

[0001] The utility model relates to the technical field of liquid distributors, in particular to an adjustable liquid distributor. Background Art

[0002] There are many fields in the chemical separation process that require distillation towers. The towers are divided into plate type and packed type. The packed towers should be filled in sections according to different packing types. A certain height is left between the sections for the installation of liquid distributors. The separation efficiency of a small-diameter packed tower is not sensitive to the uniform distribution of the fluid. The packing efficiency of a large-diameter tower has a lot to do with the initial distribution of the fluid, that is, there is an amplification effect. A good liquid distributor can minimize the amplification effect, so that the packing efficiency can be fully utilized, the separation efficiency can be improved, the reflux ratio can be reduced, the heat load can be reduced, and the energy-saving effect can be achieved.

[0003] The common tube-type liquid distributor on the market now realizes liquid distribution by evenly opening injection holes directly on the liquid distribution pipe. Since the injection pressure of the injection holes on the surface of the liquid distribution pipe cannot be adjusted, when a small amount of liquid enters the tube-type liquid distributor, there is insufficient pressure, the range of liquid injection is reduced, and the working efficiency of the tube-type liquid distributor is reduced. In view of the above situation, technical innovation is carried out on the basis of the existing liquid distributor. Utility Model Content

[0006] A tube-type liquid distributor, wherein a waterproof motor is provided at the bottom of the tube-type liquid distributor, wherein:

[0007] A gear is provided at the bottom of the output end of the waterproof motor, and two sets of racks are evenly meshed on the outer side wall of the gear;

[0008] A skateboard, wherein adjustment holes are evenly opened on the top of the skateboard, a sealing gasket is arranged at the bottom of the skateboard, a connecting frame is arranged on the outer side of the rack, a connecting plate is evenly arranged on the top of the connecting frame, and the skateboard is arranged on the top of the connecting plate.

[0009] Preferably, the slide plate is evenly arranged on the top of the liquid distribution pipe of the calandria type liquid distributor, and the adjustment holes of the slide plate are aligned with the injection holes on the liquid distribution pipe of the calandria type liquid distributor.

[0010] Preferably, the bottom of the sealing gasket fits with the top of the liquid distribution pipe of the calandria type liquid distributor, and the adjustment hole of the slide plate has the same size as the injection hole on the liquid distribution pipe of the calandria type liquid distributor.

[0011] Preferably, the outer side wall of the liquid distribution pipe of the tube-type liquid distributor is evenly provided with two groups of guide grooves, and the inner side wall of the slide plate is evenly provided with two groups of guide strips, and the guide strips are arranged in the guide grooves.

[0013] Preferably, two groups of reinforcing plates are evenly arranged on the outer side wall of the rack, and one end of the reinforcing plate away from the rack is fixedly arranged on the outer side of the connecting frame.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] The utility model drives the slide plate to move by a waterproof motor. When the slide plate moves, the adjustment hole on the slide plate will be staggered with the injection hole on the liquid distribution pipe of the tube-type liquid distributor, so as to change the opening size of the injection hole on the liquid distribution pipe of the tube-type liquid distributor, thereby achieving the effect of adjusting the injection pressure. When a small amount of liquid enters the tube-type liquid distributor, the injection pressure can be adjusted to expand the injection range of the liquid, thereby improving the working efficiency of the tube-type liquid distributor.

A waterproof motor 4 is fixedly arranged at the bottom of the tube-type liquid distributor 1. A gear 41 is fixedly arranged at the bottom of the output end of the waterproof motor 4. Two sets of racks 32 are evenly meshed on the outer wall of the gear 41. Adjustment holes are evenly penetrated on the top of the slide plate 2. A sealing gasket 21 is fixedly arranged at the bottom of the slide plate 2. A connecting frame 3 is fixedly arranged on the outer side of the rack 32. A connecting plate 31 is evenly fixedly arranged on the top of the connecting frame 3. The slide plate 2 is fixedly arranged on the connecting plate 31. The slide plate 2 is evenly slidably arranged on the top of the liquid distribution pipe of the tube-type liquid distributor 1. The adjustment hole of the slide plate 2 is aligned with the injection hole on the liquid distribution pipe of the tube-type liquid distributor 1. The slide plate 2 is assisted by the guide bar 22 to perform stable linear motion. The waterproof motor 4 drives the gear 41 to rotate and then drives the two sets of racks 32 to move outward synchronously. When the racks 32 move outward, the slide plate 2 is driven to move synchronously through the connecting frame 3 and the connecting plate 31. When the slide plate 2 moves, the adjustment hole on the slide plate 2 will align with the injection hole on the tube-type liquid distributor 1. The injection holes on the liquid distribution pipe are staggered to change the opening size of the injection holes on the liquid distribution pipe of the tube-type liquid distributor 1, thereby achieving the effect of adjusting the injection pressure. The bottom of the sealing gasket 21 fits with the top of the liquid distribution pipe of the tube-type liquid distributor 1, and the connecting gap between the slide plate 2 and the liquid distribution pipe of the tube-type liquid distributor 1 can be sealed by the sealing gasket 21. The adjustment hole of the slide plate 2 has the same size as the injection hole on the liquid distribution pipe of the tube-type liquid distributor 1. Two sets of guide grooves are evenly opened on the outer wall of the liquid distribution pipe of the tube-type liquid distributor 1. The slide plate 2 is evenly and fixedly provided with two groups of guide bars 22, which are slidably arranged in the guide grooves, and a limit plate 42 is fixedly provided at the bottom of the gear 41, and the limit plate 42 is located below the two groups of racks 32. The limit plate 42 can make the two groups of racks 32 more stably mesh with the gear 41, and the outer wall of the rack 32 is evenly and fixedly provided with two groups of reinforcing plates 5, and one end of the reinforcing plate 5 away from the rack 32 is fixedly provided on the outer side of the connecting frame 3, and the reinforcing plate 5 can improve the connection stability between the rack 32 and the connecting frame 3.

[0024] Working principle: The guide bar 22 assists the slide plate 2 to perform stable linear motion, and the waterproof motor 4 drives the gear 41 to rotate and then drives the two sets of racks 32 to move outward synchronously. When the rack 32 moves outward, the slide plate 2 will be driven to move synchronously through the connecting frame 3 and the connecting plate 31. When the slide plate 2 moves, the adjustment hole on the slide plate 2 will be staggered with the injection hole on the liquid distribution pipe of the tube-type liquid distributor 1, thereby changing the opening size of the injection hole on the liquid distribution pipe of the tube-type liquid distributor 1, thereby achieving the effect of adjusting the injection pressure.
