Description

Technical Field

[0001] The utility model relates to the technical field of vacuum evaporation, in particular to a dirt environmentally friendly treatment structure for vacuum evaporation drying. Background Art

[0002] Vacuum evaporation is an evaporation operation performed under vacuum. In the vacuum evaporation process, the solution (including domestic sewage, chemical wastewater and other industrial sewage) is in a vacuum state, and the solution generates secondary steam due to the heat conduction of steam. However, since the steam fails to effectively contact the solution, the solution is heated unevenly, which affects the evaporation and drying effect.

[0003] Therefore, the current vacuum evaporation drying process has the problem of uneven heating of the solution, slow heat conduction, and low evaporation efficiency. Utility Model Content

[0004] The utility model aims at the technical problems existing in the prior art and provides a dirt environmental protection treatment structure of vacuum evaporation drying to solve the problems of uneven heating of the solution, slow heat conduction and low evaporation efficiency.

[0005] The utility model solves the above technical problems with the following technical solutions: A vacuum evaporation and drying dirt environmental protection treatment structure, comprising:

[0006] Vacuum tank;

[0007] A stirring assembly, the stirring assembly comprising a main shaft, a plurality of stirring rods, and a plurality of rotating blades, one end of the main shaft is rotatably connected to the side wall of the vacuum tank through a rotating shaft, the plurality of rotating blades surround the outer side of the main shaft along the circumference of the main shaft, and the plurality of stirring rods are sequentially distributed at both ends of the main shaft along the axis of the main shaft;

[0008] The heating part is arranged below the vacuum tank and is used to generate steam, wherein the heating part includes an introduction component connected to the vacuum tank to introduce the generated steam into the vacuum tank and spray it toward the rotating blades.

[0009] The beneficial effects of the utility model are:

[0010] 1) The device sets a rotatable main shaft and rotating blades in the vacuum tank, and introduces steam into the vacuum tank through an introduction component and sprays it toward the rotating blades. The rotating blades are driven by the power of the steam spray, thereby driving the main shaft to rotate. At the same time, the rotating main shaft drives the stirring rod to rotate, so that the solution and the steam are effectively stirred and mixed, and the solution and the steam are fully mixed, which effectively improves the uniformity of the solution being heated, accelerates the heat conduction process, and thus improves the evaporation efficiency. In summary, the device uses steam as a driving force instead of using energy to drive, drives the steam to stir and mix with the material in the vacuum tank, while saving energy consumption and accelerating the drying rate of the material.

[0011] On the basis of the above technical solution, the present invention can also be improved as follows.

[0012] Furthermore, the introduction component is composed of a metal tube that is continuously bent at right angles in the shape of a Chinese character "bow", and extends to the area below the rotating blades.

[0013] Further, the axis of the metal tube deviates from the axis of the main shaft.

[0014] The beneficial effect of adopting the above further scheme is that by allowing the axis of the metal tube to deviate from the axis of the main shaft, it is ensured that the steam ejected from the metal tube can deviate from the axis of the main shaft, so that the ejected steam can contact the rotating blades more effectively, thereby driving the rotating blades to rotate. The rotation of the rotating blades will further drive the main shaft to rotate, thereby achieving a more complete mixing of the material and the steam, improving the uniformity of heating of the material and the evaporation efficiency, and accelerating the drying process of the solution.

[0015] Furthermore, a plurality of nozzles are arranged on the outer side of one end of the metal tube close to the rotating blades, and the nozzles are arranged toward the rotating blades respectively.

[0016] The beneficial effect of adopting the above further scheme is that by arranging a plurality of nozzles on the outer side of one end of the metal tube close to the rotating blades and ensuring that these nozzles are respectively arranged toward the rotating blades, the contact between the steam and the rotating blades is effectively enhanced, thereby increasing the force of the steam to drive the rotating blades to rotate.

[0017] Furthermore, the metal tube is a copper tube.

[0018] The beneficial effect of adopting the above further scheme is that the copper tube is continuously bent at right angles in the shape of a "bow" and extends to the area below the rotating blades. During the process of the copper tube conveying steam, the temperature of the surface of the copper tube increases due to heat conduction, so that the heat is transferred to the material in the vacuum tank through the copper tube, so that the material in the vacuum tank can be preheated in advance, effectively accelerating the heating and drying process of the material. Through the heat conduction of the copper tube, the material can begin to be heated before it comes into contact with the steam, thereby improving the efficiency and uniformity of heating.

[0019] Furthermore, the number of the stirring rods is four, wherein two of the stirring rods are arranged at one end of the main shaft, and the other two of the stirring rods are arranged at the other end of the main shaft.

[0020] Furthermore, both sides of each rotating blade are provided with a blocking structure, and the blocking structure is a resistance groove.

[0021] The beneficial effect of adopting the above-mentioned further scheme is that by opening resistance grooves on both sides of the rotating blades, the steam can stay in the resistance grooves when contacting the blades, thereby increasing the force of the steam on the rotating blades, increasing the contact time and surface area of ​​the steam and the blades, and helping to drive the main shaft to rotate more effectively.

[0027] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0028] Vacuum evaporation is an evaporation operation performed under vacuum. In the vacuum evaporation process, the solution (including domestic sewage, chemical wastewater and other industrial sewage) is in a vacuum state, and the solution generates secondary steam due to the heat conduction of steam. However, since the steam fails to effectively contact the solution, the solution is heated unevenly, which affects the evaporation and drying effect.

[0029] Therefore, the current vacuum evaporation drying process has problems such as uneven heating of the solution, slow heat conduction, and low evaporation efficiency. The utility model proposes a vacuum evaporation drying dirt environmental protection treatment structure to solve the above problems.

[0030] The utility model provides the following preferred embodiments

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, a vacuum evaporation and drying dirt environmental protection treatment structure comprises:

[0032] Vacuum tank 100;

[0033] A stirring assembly 200, the stirring assembly 200 comprises a main shaft 201, a plurality of stirring rods 202, and a plurality of rotating blades 203, one end of the main shaft 201 is rotatably connected to the side wall of the vacuum tank 100 through a rotating shaft, the plurality of rotating blades 203 surround the outer side of the main shaft 201 along the circumference of the main shaft 201, and the plurality of stirring rods 202 are sequentially distributed at both ends of the main shaft 201 along the axis of the main shaft 201;

[0034] The heating part 300 is disposed below the vacuum tank 100 and generally uses a heating pipe to heat water to generate steam, wherein the heating part 300 includes an introduction component connected to the vacuum tank 100 to introduce the generated steam into the vacuum tank 100 and spray it toward the rotating blades 203;

[0035] By arranging a rotatable main shaft 201 and a rotating blade 203 in the vacuum tank 100, and introducing steam into the vacuum tank 100 through an introduction component and spraying it toward the rotating blade 203, the rotating blade 203 is driven by the power of the steam spray, thereby driving the main shaft 201 to rotate. At the same time, the rotating main shaft 201 drives the stirring rod 202 to rotate, so that the solution and the steam are effectively stirred and mixed, and the solution and the steam are fully mixed, which effectively improves the uniformity of the solution being heated, accelerates the heat conduction process, and thus improves the evaporation efficiency. In summary, the device uses steam as a driving force instead of using energy to drive, drives the steam to stir and mix with the material in the vacuum tank 100, while saving energy consumption and accelerating the drying rate of the material.

[0036] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the axis of the metal tube deviates from the axis of the main shaft 201. By allowing the axis of the metal tube to deviate from the axis of the main shaft 201, it is ensured that the steam ejected from the metal tube can deviate from the axis of the main shaft 201, so that the ejected steam can more effectively contact the rotating blades 203, thereby driving the rotating blades 203 to rotate. The rotation of the rotating blades 203 will further drive the main shaft 201 to rotate, thereby achieving a more complete mixing of the material and the steam, improving the uniformity of the heating of the material and the evaporation efficiency, and accelerating the drying process of the solution.

[0037] In this embodiment, Figure 1 , Figure 2 and Figure 3As shown, a plurality of nozzles 311 are provided on the outer side of one end of the metal tube close to the rotating blade 203, and the nozzles 311 are respectively arranged toward the rotating blade 203. By providing a plurality of nozzles 311 on the outer side of one end of the metal tube close to the rotating blade 203 and ensuring that these nozzles 311 are respectively arranged toward the rotating blade 203, the contact between the steam and the rotating blade 203 is effectively enhanced, thereby enhancing the force of the steam to drive the rotating blade 203 to rotate.

[0038] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the introduction component is composed of a metal tube that is continuously bent at right angles in the shape of a "bow" and extends to the area below the rotating blade 203. The metal tube is a copper tube 310. The copper tube 310 is continuously bent at right angles in the shape of a "bow" and extends to the area below the rotating blade 203. During the process of the copper tube 310 conveying steam, the temperature of the surface of the copper tube 310 increases due to heat conduction, so that the heat is transferred to the material in the vacuum tank 100 through the copper tube 310, so that the material in the vacuum tank 100 can be preheated in advance, effectively accelerating the heating and drying process of the material. Through the heat conduction of the copper tube 310, the material can be heated before it comes into contact with the steam, thereby improving the efficiency and uniformity of heating.

[0039] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the number of the stirring rods 202 is four, wherein two of the stirring rods 202 are arranged at one end of the main shaft 201 , and the other two of the stirring rods 202 are arranged at the other end of the main shaft 201 .

[0040] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, each of the rotating blades 203 is provided with an obstruction structure on both sides, and the obstruction structure is a resistance groove 400. By opening the resistance groove 400 on both sides of the rotating blade 203, the steam can stay in the resistance groove 400 when contacting the blade, thereby increasing the force of the steam on the rotating blade 203, increasing the contact time and surface area of ​​the steam and the blade, and helping to drive the main shaft 201 to rotate more effectively.

[0041] The specific working process of the utility model is as follows:

[0042] By allowing the axis of the metal tube to deviate from the axis of the main shaft 201, it is ensured that the steam ejected from the metal tube can deviate from the axis of the main shaft 201, so that the ejected steam can more effectively contact the rotating blades 203, thereby driving the rotating blades 203 to rotate. The rotation of the rotating blades 203 will further drive the main shaft 201 to rotate, thereby achieving a more complete mixing of the material and the steam.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
