Description

Technical Field

[0001] The utility model relates to the technical field of chemical industry, in particular to a distillation kettle with a steam recovery mechanism. Background Art

[0002] With the continuous development of industrial technology, stills are increasingly used in the chemical, pharmaceutical and other fields. During operation, stills generate large amounts of steam. Directly discharging this steam into the atmosphere not only wastes energy but also pollutes the environment. Therefore, recycling the steam generated by stills is of great practical significance.

[0003] At present, there are some technical solutions for the recovery of steam from distillation kettles. Among them, the utility model patent with application number 2023229722674 adopts a solution in which the steam serpentines in a recovery box to condense. However, this solution has certain limitations. Because the steam serpentines in the recovery box, its flow path is long, resulting in a slow steam flow rate. This not only affects the efficiency of condensation, but may also make the entire steam recovery process take longer, reducing production efficiency. In addition, the slower steam flow rate may also cause some steam to be discharged from the recovery system without being fully condensed, thereby reducing the steam recovery rate.

[0004] In order to solve the problems existing in the prior art and improve the efficiency and utilization rate of steam recovery of a distillation kettle, the utility model proposes a distillation kettle with a steam recovery mechanism. Utility Model Content

[0005] In order to solve the above problems, the utility model designs a distillation kettle with a steam recovery mechanism.

[0006] In order to achieve the above technical objectives and the above technical effects, the present invention is implemented through the following technical solutions:

[0007] A distillation kettle with a steam recovery mechanism comprises a cylinder, a top wall of the cylinder is provided with a transverse pipe via a plurality of connecting pipes, an outer top end of the transverse pipe is provided with an air inlet pipe, and a bottom wall of the cylinder is provided with a liquid discharge pipe;

[0008] The left inner wall of the cylinder is rotatably connected to a round rod via a sealed bearing. A shell is provided on the left wall of the cylinder, and the left end of the round rod extends into the shell. A drain pipe is provided on the outer wall of the shell.

[0009] A second shell is provided on the right side wall of the cylinder, a water inlet pipe is provided on the outer wall of the second shell, a motor is provided on the side wall of the second shell, the left and right inner walls of the second shell are rotatably connected with a rotating rod through a second sealed bearing, and the right end of the rotating rod is fixedly connected to the output end of the motor through a coupling, a through hole is opened through the outer wall of the rotating rod, and the left end of the rotating rod extends into the cylinder, the inner ends between the round rod and the rotating rod are provided with circular plates, and a plurality of water pipes are provided on the inner walls between the circular plates.

[0010] Furthermore, the connecting pipes are arranged at intervals on the top of the outer wall of the cylinder from left to right.

[0011] Furthermore, the outer ring of the second sealed bearing is fixedly connected to the inner wall of the second housing via a bearing seat, and the inner ring of the second sealed bearing is interference fit connected to the outer wall of the rotating rod.

[0012] Furthermore, the water pipes are arranged between the circular plates with circumferential gaps.

[0013] Furthermore, the water inlet pipe, the second shell, the rotating rod, the circular plate, the water guide pipe, the circular rod, the first shell and the drain pipe are connected.

[0014] The beneficial effects of the utility model are:

[0015] The rotatable condenser tube group can continuously change the contact position and angle between the steam and the condenser tube during the stirring process, making the heat exchange between the steam and the condenser tube more sufficient. Compared with traditional fixed condenser tubes, this dynamic contact method greatly increases the area and frequency of heat exchange, thereby accelerating the condensation speed of steam;

[0016] The rotating condenser tube can destroy the thermal boundary layer formed by steam on the surface of the condenser tube. The thermal boundary layer is an area with a large temperature gradient, which will hinder the transfer of heat. Through continuous stirring, the thermal boundary layer is continuously destroyed and renewed, reducing thermal resistance, improving heat transfer efficiency, and allowing steam to condense into liquid faster;

[0017] The stirring action of the rotatable condenser tube group inside the cylinder can make the steam more evenly distributed throughout the space, avoiding the accumulation of steam in local areas, thus ensuring that the steam in all parts can fully contact the condenser tubes and achieve uniform condensation. This helps to improve the quality consistency of the condensed product and reduce local overheating or overcooling caused by uneven condensation;

[0018] The rotatable condenser tube group can automatically adjust the stirring speed and intensity according to the changes in steam flow. When the steam flow is large, the condenser tube group can speed up the rotation speed to enhance the condensation effect; when the steam flow is small, the condenser tube group can appropriately reduce the rotation speed to avoid excessive condensation and energy waste. This adaptive feature enables the equipment to better adapt to different production conditions and improves the flexibility and reliability of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS
