Description

Technical Field

[0001] This utility model relates to the technical field of distillation columns for bromine extraction, and in particular to a distillation column for bromine chemical extraction. Background Technology

[0002] Bromine is a chemical element, one of the halogens. Bromine molecules are volatile reddish-black liquids under standard temperature and pressure, with reactivity between chlorine and iodine. Pure bromine is also called bromine. Bromine and its compounds can be used as flame retardants, water purifiers, pesticides, dyes, etc.

[0003] Bromine purification generally requires distillation, necessitating the use of distillation columns. Existing distillation columns used for bromine chemical extraction, such as the two-stage distillation column for bromine extraction disclosed in utility model patent CN222641262U, employ a product discharge pipe at the bottom of the column body, a reflux port at the bottom of the product discharge pipe, and a reflux pipe at the output end of the reflux port. This allows the reflux pipe to reflux the liquid at the bottom of the distillation column back into the reboiler via a first guide pipe, preventing residual bromine in the cooled liquid from being discarded as a solution during distillation, thus avoiding resource waste.

[0004] The distillation column used in the bromine chemical extraction process described in the above patent can effectively avoid the waste of resources, but it still has the following drawbacks: the control assembly installed in front of the reboiler has a fixed height that cannot be adjusted, which makes it inconvenient for operators of different heights to use and is not practical enough. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a distillation column for bromine chemical extraction that can adjust the height of the control assembly, making it more convenient for operators of different heights and improving its practicality.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a distillation column for bromine chemical extraction, comprising a base, a reboiler disposed on one side of the top of the base, a control assembly disposed on the front of the reboiler, and an adjustment mechanism for adjusting the height of the control assembly disposed on the front of the reboiler, the adjustment mechanism comprising two sets of connecting plates, the two sets of connecting plates being fixedly connected to the front of the reboiler, two sets of guide rods being fixedly connected between the two sets of connecting plates, an adjusting screw being rotatably mounted on the two sets of connecting plates, the two sets of guide rods being symmetrically distributed on the left and right sides of the adjusting screw, a transmission sleeve being screwed onto the adjusting screw, the transmission sleeve being slidably mounted on the two sets of guide rods, a connecting frame being fixedly connected to the front end of the transmission sleeve, the control assembly being mounted on the connecting frame, a support plate being fixedly connected to the front end of the lower set of connecting plates, a transmission worm being rotatably mounted between the support plate and the front of the reboiler, a handwheel being fixedly mounted at the front end of the transmission worm, and a worm wheel being fixedly mounted at the bottom end of the adjusting screw, the worm wheel meshing with the transmission worm.

[0008] Preferably, the top of the connecting frame is symmetrically fitted with two sets of wing bolts, and the back of the connecting frame is provided with a heat dissipation vent. The control assembly is installed on the connecting frame by the tightening action of the wing bolts.

[0009] Preferably, a fastening pad is fixedly connected to the inner side of the connecting frame.

[0010] Preferably, the transmission sleeve plate has two sets of sliding holes symmetrically formed, and a sliding sleeve is fixedly installed in each set of sliding holes. The transmission sleeve plate is slidably mounted on the two sets of guide rods through the cooperation of the sliding sleeves.

[0011] Preferably, two sets of reinforcing plates are fixedly connected between the outer sides of the two sets of connecting plates and the outer wall of the reboiler.

[0012] Preferably, the outer wall of the handwheel is provided with a ring array of multiple sets of anti-slip protrusions.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When using the control assembly, the operator rotates the transmission worm gear through the handwheel, causing the transmission worm gear to drive the adjusting screw to rotate through the worm wheel. This, in turn, causes the adjusting screw to drive the transmission sleeve plate to slide along the guide rod. The transmission sleeve plate then drives the control assembly to move through the connecting frame, thereby adjusting the height of the control assembly. The operator can adjust the height of the control assembly to an appropriate height according to their own height. The meshing between the worm wheel and the transmission worm gear has a self-locking effect, preventing the adjusting screw from rotating on its own. This allows the control assembly to remain stationary after being adjusted to an appropriate height, thus enabling height adjustment of the control assembly. This provides convenience for operators of different heights and improves practicality. Attached Figure Description

[0019] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0020] Example

[0021] Please see Figures 1-4 This utility model discloses a distillation column for bromine chemical extraction, comprising a base and two sets of connecting plates. A reboiler is installed on one side of the top of the base, and a control assembly is mounted on the front of the reboiler. The two sets of connecting plates are fixedly connected to the front of the reboiler, and two sets of guide rods are fixedly connected between the two sets of connecting plates. An adjusting screw is rotatably mounted on the two sets of connecting plates. The two sets of guide rods are symmetrically distributed on the left and right sides of the adjusting screw. A transmission sleeve is screwed onto the adjusting screw, and the transmission sleeve is slidably mounted on the two sets of guide rods. A connecting frame is fixedly connected to the front end of the transmission sleeve, and the control assembly is mounted on the connecting frame. A support plate is fixedly connected to the front end of the lower set of connecting plates, and a transmission worm gear is rotatably mounted between the support plate and the front of the reboiler. A handwheel is fixedly mounted at the front end of the transmission worm gear. A worm gear is fixedly sleeved at the bottom of the lead screw, and the worm gear meshes with the transmission worm. During use, the operator rotates the transmission worm via the handwheel, causing the worm gear to drive the adjusting lead screw to rotate. This, in turn, causes the adjusting lead screw to slide along the guide rod, and the transmission sleeve moves the control assembly via the connecting frame. This allows for height adjustment of the control assembly. The operator can adjust the height of the control assembly to a suitable level according to their own height. The meshing of the worm gear and the transmission worm has a self-locking function, preventing the adjusting lead screw from rotating on its own. This ensures that the control assembly remains stationary after being adjusted to the appropriate height, providing convenience for operators of different heights and improving practicality.

[0022] Two sets of wing bolts are symmetrically screwed onto the top of the connecting frame. A heat dissipation vent is provided on the back of the connecting frame. The control assembly is mounted on the connecting frame by the tightening action of the wing bolts. During installation, the control assembly is placed on the connecting frame, with its bottom end abutting against the inner bottom of the connecting frame and its top end contacting the inner top of the connecting frame. The wing bolts are then tightened appropriately, pressing their bottom ends against the top of the control assembly. The wing bolts clamp the control assembly onto the connecting frame, completing the installation. The heat dissipation vent serves a cooling function. Disassembly is simple; just loosen the wing bolts to remove the control assembly, making assembly and disassembly easier and facilitating future repairs.

[0023] The inner side of the connecting frame is fixedly connected with a fastening rubber pad; by setting the fastening rubber pad, the control assembly can be more securely and reliably fitted onto the connecting frame.

[0024] The transmission sleeve plate has two sets of symmetrical sliding holes, and a sliding sleeve is fixed in each set of sliding holes. The transmission sleeve plate is slidably fitted onto the two sets of guide rods through the cooperation of the sliding sleeves. By setting the sliding sleeves, the transmission sleeve plate slides more smoothly on the guide rods.

[0025] Two sets of reinforcing plates are fixedly connected between the outer sides of the two sets of connecting plates and the outer wall of the reboiler; by setting the reinforcing plates, the stability of the connection between the connecting plates and the reboiler can be improved, and the connection between the connecting plates and the base can be made more secure.

[0026] Multiple sets of anti-slip ridges are fixedly arranged in a ring array on the outer wall of the handwheel; by setting the anti-slip ridges, the hand can be prevented from slipping and slipping out when the hand is holding the handwheel to rotate the transmission worm gear.

[0027] This utility model discloses a distillation column for bromine chemical extraction. Its working principle is as follows: When using the control assembly, the operator rotates the transmission worm gear via the handwheel. This worm gear drives the adjusting screw to rotate, which in turn causes the adjusting screw to slide along the guide rod. The transmission sleeve then moves the control assembly via the connecting frame, thus adjusting the height of the control assembly. The operator can adjust the height of the control assembly to a suitable level according to their own height. The meshing between the worm gear and the transmission worm gear has a self-locking effect, preventing the adjusting screw from rotating on its own. This ensures that the control assembly remains stationary after being adjusted to the appropriate height. During installation, the control assembly is placed on the connecting frame, with its bottom end resting against the inner side of the connecting frame. The top of the control assembly contacts the inner top of the connecting frame, and then the wing bolts are tightened appropriately so that the bottom of the wing bolts presses against the top of the control assembly. The control assembly is fixed to the connecting frame by the clamping of the wing bolts, completing the installation. The heat dissipation port serves to dissipate heat. When disassembling, simply loosen the wing bolts to remove the control assembly, making the disassembly and assembly of the control assembly more convenient and easy to disassemble during later maintenance. In addition, the base, reboiler and control assembly are referenced from a two-stage distillation column for bromine extraction with patent publication number CN222641262U, which belongs to the published prior art. The remaining specific structure and working principle have been described in detail in the published patent, so they will not be elaborated here.

[0028] The present invention relates to a distillation column for bromine chemical extraction. Its installation, connection, or setting methods are all common mechanical methods, and any method that can achieve its beneficial effects can be implemented.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
