Description

Technical Field

[0001] This utility model relates to the field of evaporator technology, specifically to a built-in evaporator. Background Technology

[0002] Evaporators are commonly used in chemical wastewater treatment or chemical production processes for evaporation concentration and crystallization. Essentially, an evaporator is a heat exchanger where the material exchanges heat with a heat source (steam). Some of the solvent (usually water) in the material turns into a gaseous state and is separated out, increasing the material's concentration and achieving the purpose of evaporation concentration. The principle of an evaporator is to use evaporation to heat a solution, causing some of the solvent to vaporize and be removed, thereby increasing the solution concentration—the process of solution concentration. The equipment used for evaporation is called an evaporator, and evaporation operations are widely used in industries such as chemical, food, and pharmaceutical.

[0003] Currently, the existing "a built-in evaporator, announcement number: CN 203663463 U" places the heat exchanger inside the tank to minimize heat loss. Steam flows in the S-shaped heating pipe to heat the material inside the tank, extending the heating time of the steam as much as possible and improving thermal efficiency. However, some raw material liquid will remain in the evaporated material, and the device cannot achieve cyclic evaporation, which will cause waste of raw material liquid.

[0004] Therefore, a built-in evaporator is needed to improve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a built-in evaporator to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An internal evaporator includes an evaporator tank. A support frame is installed at the bottom of the evaporator tank, and a heat exchanger is installed on the top of the support frame. A steam inlet pipe is installed on the left side of the top of the heat exchanger, and a condensate outlet is installed on the right side of the top of the heat exchanger. Support legs are evenly distributed on the outer wall of the evaporator tank. A feeding pipe is installed at the top of the evaporator tank, and a discharge pipe is installed at the bottom of the evaporator tank. A separation box is installed at the lower end of the discharge pipe. A solid-liquid separation plate is installed inside the separation box, and a discharge port is installed on the front of the separation box. A pump body is installed on the lower right side of the separation box, and a circulation pipe is installed on the right side of the pump body. An exhaust pipe is installed on the upper right side of the evaporator tank.

[0008] As a preferred embodiment of this utility model, the evaporator is divided into a tank body and a tank cover, with a feeding pipe installed on the tank cover, and an observation window provided on the front of the evaporator.

[0009] As a preferred embodiment of this utility model, the ports of the steam inlet pipe and the condensate outlet both penetrate the side wall of the evaporator.

[0010] As a preferred embodiment of this utility model, a solenoid valve is installed on the discharge pipe.

[0011] As a preferred embodiment of this utility model, the solid-liquid separation plate is inclined towards the discharge port inside the separation box.

[0012] As a preferred embodiment of this utility model, the circulating pipe has an external structure of "]" shape, and the upper end of the circulating pipe is connected to the body of the evaporator.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, the solid-liquid separation plate, discharge port, pump body and circulation pipeline can separate the evaporated material into solid and liquid. If there is still liquid in the evaporated material, the liquid is pumped into the evaporation tank for re-evaporation, thereby reducing waste and improving the evaporation effect.

[0025] An internal evaporator includes an evaporator tank 1. A support frame 2 is installed at the bottom inside the evaporator tank 1. A heat exchanger 3 is installed on the top of the support frame 2. A steam inlet pipe 4 is installed on the left side of the top of the heat exchanger 3. A condensate outlet 5 is installed on the right side of the top of the heat exchanger 3. Support legs 6 are evenly arranged on the outer wall of the evaporator tank 1. A feeding pipe 7 is installed on the top of the evaporator tank 1. A discharge pipe 8 is installed at the bottom of the evaporator tank 1. A separation box 9 is installed at the lower end of the discharge pipe 8. A solid-liquid separation plate 10 is installed inside the separation box 9. A discharge port 11 is installed on the front of the separation box 9. A pump body 12 is installed on the lower right side of the separation box 9. A circulation pipe 13 is installed on the right side of the pump body 12. An exhaust pipe 14 is installed on the upper right side of the evaporator tank 1.

[0026] In this embodiment, the evaporator 1 is divided into a tank body and a tank cover. The feeding pipe 7 is installed on the tank cover. An observation window is provided on the front of the evaporator 1. The ports of the steam inlet pipe 4 and the condensate outlet 5 both penetrate the side wall of the evaporator 1. A solenoid valve is installed on the discharge pipe 8. The solid-liquid separation plate 10 is inclined towards the discharge port 11 inside the separation box 9. The circulation pipe 13 has a "]" shaped structure, and the upper end of the circulation pipe 13 is connected to the tank body of the evaporator 1. Through the separation box 9, solid-liquid separation plate 10, discharge port 11, pump body 12, and circulation pipe 13, the evaporated material can be separated into solid and liquid. If there is still liquid in the evaporated material, the liquid is pumped back into the evaporator 1 for re-evaporation, thereby reducing waste and improving the evaporation effect.

[0027] The working process of this utility model is as follows: First, liquid material is added into evaporator 1 through feeding pipe 7. Then, steam is input into heat exchanger 3 through steam inlet pipe 4. The steam flows in the S-shaped heating pipe to heat the material in evaporator 1. After heat exchange, the liquefied condensate is discharged through condensate outlet 5. The steam generated during the heat exchange process is discharged from exhaust pipe 14 at the top of tank 1. The heated solid material enters separation box 9 through discharge pipe 8 at the bottom of evaporator 1. Then, it is filtered and separated by solid-liquid separation plate 10. At this time, the solid material will be discharged from discharge pipe 8. Then, the filtered liquid will be pumped back into evaporator 1 for evaporation. Through the separation box 9, solid-liquid separation plate 10, discharge port 11, pump body 12, and circulation pipe 13, the evaporated material can be separated into solid and liquid. If there is still liquid in the evaporated material, the liquid will be pumped back into evaporator 1 for evaporation again, thereby reducing waste and improving the evaporation effect.
