Description

Technical Field

[0001] This utility model relates to the field of chemical distillation equipment technology, specifically a distillation kettle for chemical production. Background Technology

[0002] Chemical production is an important industrial manufacturing process that involves the application of numerous chemical and physical principles. Its main task is to process various raw materials through specific technological conditions and equipment, transforming them into chemical products with specific properties and uses. Distillation is a common reaction step in chemical production, and distillation operations typically utilize a distillation kettle.

[0003] Currently, existing chemical production distillation kettles can only achieve material separation through heating, vaporization, and condensation. However, these processes cannot pre-treat the materials, leading to prolonged distillation times and reduced chemical production efficiency. Therefore, there is a need to develop a chemical production distillation kettle capable of pre-treating materials to improve production efficiency. Utility Model Content

[0004] To address the above technical problems, this utility model provides a chemical production distillation kettle that can pre-treat materials and improve chemical production efficiency, thereby solving the problem that the lack of material pre-treatment process in existing chemical production distillation kettles affects production efficiency.

[0005] To solve the above-mentioned technical problems, the present invention provides a distillation kettle for chemical production, comprising a base plate, a distillation tank fixedly connected to the base plate, a heating box sleeved on the outside of the distillation tank, a support frame fixedly connected to the upper surface of the base plate, a feed pipe and a discharge pipe fixedly connected to the top of the distillation tank, a heat-conducting ring spirally sleeved on the outside of the feed pipe, a heating plate fixedly connected to the top of the heat-conducting ring, the heating plate being fixedly connected to the bottom surface of the support frame, a heat-conducting cylinder fixedly connected to the outer surface of the discharge pipe, a condenser tube fixedly connected to the outer surface of the heat-conducting cylinder, one end of the condenser tube being fixedly connected to a first water pump and the other end being fixedly connected to a second water pump, a first liquid storage tank and a second liquid storage tank fixedly connected to the upper surface of the support frame, the input end of the first water pump being connected to the first liquid storage tank, the output end of the second water pump being connected to the second liquid storage tank, a third water pump fixedly connected to one side of the first liquid storage tank, and the input end of the third water pump being fixedly connected to one side of the second liquid storage tank.

[0006] Furthermore, a temperature sensor is fixedly connected to the inner wall of the heating box.

[0007] Furthermore, a control panel is fixedly connected to the upper surface of the base plate, and a reinforcing frame is fixedly connected to the outer side of the control panel.

[0008] Furthermore, a fixed base is fixedly connected to the bottom surface of the base plate, and two fixed rings are fixedly connected to the outer surface of the fixed base, with the top end of each fixed ring being fixedly connected to the bottom surface of the base plate.

[0009] Furthermore, a reinforcing plate is fixedly connected to the outer surface of the heating plate, and the reinforcing plate is fixedly connected to the bottom surface of the support frame by fixing bolts.

[0010] Furthermore, a fixing frame is fixedly connected to the outer surface of the first water pump, a limiting frame is fixedly connected to the outer surface of the second water pump, and a fixing plate is fixedly connected to the outer surface of the third water pump. The bottom surfaces of the fixing frame, the limiting frame, and the fixing plate are all fixedly connected to the upper surface of the support frame.

[0011] This utility model has the following advantages compared with the prior art:

[0012] 1. This utility model completes preheating and pretreatment by setting up a heat-conducting ring to transfer heat. Compared with the traditional distillation kettle mode of "heating only begins after the material enters the tank directly", this design can reduce the heating time of the material in the distillation tank, directly shorten the overall distillation cycle, and effectively solve the problem of "reduced efficiency in chemical production due to lack of pretreatment". It is especially suitable for batch chemical production scenarios and can significantly increase the material processing capacity per unit time.

[0013] 2. This utility model uses a first water pump to transport the condensate in the first storage tank to the condenser tube. Through heat exchange between the condenser tube and the heat-conducting cylinder, the vaporized material in the discharge pipe is quickly cooled and condensed, ensuring more thorough material separation and improving product purity. The condensed and heated liquid is returned to the second storage tank by a second water pump, and then the liquid in the second storage tank is sent back to the first storage tank by a third water pump, realizing the recycling of the condensate. This avoids the waste of condensate consumed once in traditional condensation methods, reduces production water costs, and conforms to the concept of green chemical production.

A protective sleeve is fixedly connected to the outside of the heat-conducting cylinder 18 and the condenser pipe 19. A first water pump 20 is fixedly connected to one end of the condenser pipe 19, and a second water pump 22 is fixedly connected to the other end of the condenser pipe 19.

[0022] A temperature sensor 9 is fixedly connected to the inner wall of the heating box 8, and a control panel 6 is fixedly connected to the base plate 1. The control panel 6 is used to control the heating box 8, the heating plate 15, the first water pump 20, the second water pump 22, and the third water pump 24. A reinforcing frame 7 is fixedly connected to the outer surface of the control panel 6. The bottom surface of the reinforcing frame 7 is fixedly connected to the upper surface of the base plate 1.

The fixing plate 25 can reinforce the third water pump 24 and the support frame 2 to prevent them from shaking during use.

[0025] The working principle of this embodiment is as follows:

[0026] In use, the heating plate 15 is turned on via the control panel 6. After the heating plate 15 is powered on, it transfers heat to the heat-conducting ring 14 sleeved on the outside of the feed pipe 10. The material to be distilled is injected into the distillation tank 5 at a constant speed through the feed pipe 10. During the flow of the material in the pipe, it is preheated by the wrapping heating of the heat-conducting ring 14. Compared with the traditional mode, this step can increase the initial temperature of the material when it enters the distillation tank 5, directly reducing the subsequent temperature rise consumption in the distillation tank 5. The heating box 8 is turned on via the control panel 6. The heating box 8 transfers heat to the distillation tank 5 through heat conduction. When the temperature rises to the preset boiling point of the material, the control panel 6 automatically switches to "constant temperature mode" to maintain a stable temperature and ensure that the material is fully vaporized. The vaporized material steam is discharged through the discharge pipe 11. The first water pump 20 and the second water pump 22 are started. The first water pump 20 is stably fixed by the fixing frame 21 and transports the low-temperature condensate in the first storage tank 3 to the condenser tube 19 wrapped around the heat conduction cylinder 18. The low-temperature condensate in the condenser tube 19 exchanges heat with the heat conduction cylinder 18, causing the steam to cool down rapidly to below the boiling point and condense into a liquid product. Finally, it is connected to the finished product storage tank through the end of the discharge pipe 11. After heat exchange, the condensate in the condenser tube 19 that has been heated is pumped by the second water pump 22 to the second storage tank 4 for temporary storage to avoid waste caused by direct discharge of condensate. In order to reduce the cost of production water, the condensate is circulated in a closed loop through the third water pump 24.
