Description

Technical Field

[0001] The utility model relates to the field of concentrated evaporation crystallization equipment, and particularly relates to a waste water concentrated evaporation crystallization equipment. Background Technique

In the prior art, a Chinese utility model patent with the publication document number: CN215479840U discloses a desulfurized wastewater evaporation crystallization equipment. By setting a connecting piece and a connecting cylinder, the vibration generated by the large-displacement water entering the water storage tank can be reduced. By setting a rotating cylinder, the start and stop of the air outlet for exhausting gas are controlled. While evaporating and crystallizing the wastewater, the pollution of the vapor generated by the wastewater to the environment is avoided, and it has high environmental protection performance.

[0003] However, in this document, the heater is located at the bottom position of the main body inner cavity. The evaporation speed of the wastewater is related to the surface area of the liquid. When heating the wastewater in this document, the change in the surface area of the wastewater is small, and the evaporation efficiency is slow. Moreover, the upper position in this document is far from the lower position where the heater is located, and the heat receiving efficiency is easily reduced as the distance increases, making it easy for the upper position to lose heat, which is not conducive to the rapid evaporation of the wastewater in the upper position. Therefore, improvement is needed. Summary of the Invention

[0021] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Such as Figure 1 , Figure 2 , Figure 4 and Figure 5As shown in the figure, a wastewater concentration evaporation crystallization device includes an evaporation tank 1. A tank cover 3 is fixedly connected to the evaporation tank 1. An electric heater 9 is fixedly connected to the bottom surface of the evaporation tank 1. An evaporation assembly 6 is movably installed on the evaporation tank 1 and the tank cover 3. The evaporation assembly 6 includes a first connecting plate 601, a first rotating rod 603, a stirring blade 604, a second connecting plate 605, a second rotating rod 608, a heat preservation sleeve 611 and a discharge pipe 615. The first connecting plate 601 is fixedly connected in the evaporation tank 1. The first rotating rod 603 is movably installed on the first connecting plate 601. The stirring blade 604 is fixedly connected to one end of the first rotating rod 603. The second connecting plate 605 is fixedly installed on the outer side of the evaporation tank 1. The second rotating rod 608 is movably installed with the evaporation tank 1. Support feet 2 are fixedly connected to the bottom surface of the evaporation tank 1. The electric heater 9 is located at the center of the support feet 2. A discharge pipe 4 is fixedly connected to the evaporation tank 1 at the side position of the electric heater 9. A valve 5 is movably installed on the discharge pipe 4. The tank cover 3 and the evaporation tank 1 are fixedly connected by bolts 7 and nuts 8. The evaporation assembly 6 further includes a first bearing 602, a second bearing 607 and a stepping motor 606. The first rotating rod 603 is movably installed with the first connecting plate 601 through the first bearing 602. The second rotating rod 608 is movably installed with the evaporation tank 1 through the second bearing 607. The stepping motor 606 is fixedly connected to the second connecting plate 605. One end of the second rotating rod 608 is fixedly connected to the output shaft of the stepping motor 606 through a coupling. The evaporation assembly 6 further includes a first transmission gear 609 and a second transmission gear 610. The first transmission gear 609 is fixedly connected to the first rotating rod 603. The second transmission gear 610 is fixedly connected to the other end of the second rotating rod 608. The first transmission gear 609 and the second transmission gear 610 are movably installed. The stepping motor 606 rotates the second rotating rod 608. The second rotating rod 608 drives the first rotating rod 603 to rotate synchronously through the second transmission gear 610 and the first transmission gear 609. The stirring blade 604 on the first rotating rod 603 rotates synchronously. The stirring blade 604 stirs the liquid in the evaporation tank 1, causing large liquid fluctuations, increasing the liquid surface area, thereby improving the liquid evaporation efficiency. At the same time, the stirring blade 604 stirring the liquid can make the heat exchange between the upper and lower layers of the liquid more frequent, and the water temperatures of the upper and lower layers of the liquid are more uniform, which is conducive to the evaporation of the upper layer of the liquid.

[0023] As Figure 1 , Figure 2 and Figure 3As shown in the figure, the heat preservation sleeve 611 is fixedly connected to the outer side of the evaporation box 1 and is located above the second rotating rod 608. The outlet pipe 615 is fixedly connected to the box cover 3. The evaporation assembly 6 further includes an inlet pipe 612, a sealing ring 613, and a discharge pipe 614. The inlet pipe 612 is fixedly connected to the upper surface of the heat preservation sleeve 611. The sealing ring 613 is fixedly connected inside the inlet pipe 612. The outer end of the outlet pipe 615 is inserted and connected into the sealing ring 613. The discharge pipe 614 is fixedly connected to the bottom surface of the heat preservation sleeve 611. Steam evaporates from the solution, and the steam contains a large amount of heat. Therefore, through the outlet pipe 615, the steam is re-introduced into the inlet pipe 612. The sealing ring 613 prevents steam leakage. The steam enters the heat preservation sleeve 611 through the inlet pipe 612, thereby heating the heat preservation sleeve 611, keeping the temperature inside the heat preservation sleeve 611 high, facilitating the heating of the evaporation box 1 at the inner side position, and at the same time, keeping the high temperature inside the heat preservation sleeve 611 is conducive to reducing the heat dissipation efficiency of the upper layer of the evaporation box 1 to the outside, making the upper layer of liquid inside it not easy to dissipate heat outward and easier to maintain the temperature, thereby improving the efficiency of evaporation crystallization and liquid concentration.

[0024] It should be noted that the present utility model is a waste water concentration evaporation crystallization device. The waste water is introduced into the evaporation box 1, and then the box cover 3 is closed. The box cover 3 and the evaporation box 1 are fixedly closed by bolts 7 and nuts 8. The outlet pipe 615 is inserted into the heat preservation sleeve 611 of the inlet pipe 612, and then the electric heater 9 is started to heat the liquid in the box from the bottom position of the evaporation box 1. The stepping motor 606 is started, so that the second rotating rod 608 rotates in the second bearing 607. Through the meshing rotation of the second transmission gear 610 and the first transmission gear 609, the first rotating rod 603 rotates synchronously. The stirring blades 604 on the first rotating rod 603 stir the liquid, causing large liquid fluctuations, increasing the surface area of the liquid, and accelerating the efficiency of liquid evaporation crystallization and liquid concentration. After the solution boils, the water vapor moves upward and enters the outlet pipe 615 of the box cover 3. The outlet pipe 615 introduces the water vapor into the inlet pipe 612, and through the inlet pipe 612, the water vapor is introduced into the heat preservation sleeve 611. Using the large amount of heat contained in the water vapor, the space inside the heat preservation sleeve 611 is heated. The heat preservation sleeve 611 is located at the upper part of the evaporation box 1. After the heat preservation sleeve 611 obtains a high temperature, it can heat the upper part of the evaporation box 1, and through the high temperature of the heat preservation sleeve 611, the heat dissipation efficiency of the upper part of the evaporation box 1 to the outside is reduced. The upper layer of solution in the evaporation box 1 at the position where the heat preservation sleeve 611 is located is not easy to lose heat outward, and is heated by the heat inside the heat preservation sleeve 611, making the upper layer of liquid easier to evaporate crystallize and concentrate the liquid.
