Description

Technical Field

[0001] The utility model relates to the technical field of low-temperature evaporators, in particular to a split low-temperature evaporator for wastewater treatment. Background Art

[0002] A low-temperature evaporator is an efficient evaporation device. It separates and recovers the solvent in the solution by adopting a low-temperature environment and specific evaporation technologies. The low-temperature evaporator has the advantages of low energy consumption, simple operation, and little impact on heat-sensitive substances. It is widely used in industrial wastewater treatment, pharmaceuticals, chemical engineering and other fields, which can effectively reduce wastewater discharge, reduce environmental pollution, and at the same time recover valuable solutes. For example, in the pharmaceutical industry, it can be used to concentrate medicinal liquids and retain active ingredients; in wastewater treatment, it can remove harmful substances and realize the reuse of water resources. The low-temperature evaporator provides strong support for energy conservation, emission reduction and resource recovery in many industries.

[0003] The prior art such as the utility model with the publication number of CN220449850U discloses a split low-temperature evaporator for wastewater treatment. This patent adopts a main body component; the main body component includes an evaporation tank arranged, a concentrated liquid outlet connected to the lower end of the evaporation tank; an acceleration component; the acceleration component includes a flange pipe connected to the concentrated liquid outlet, a first sealing ring connected to the flange pipe, multiple groups of bolts for fixing the flange pipe, an opening formed in the middle of the flange pipe, a second sealing ring and an arc-shaped cover plate connected to the opening, a motor connected to the side of the arc-shaped cover plate, a rotating shaft connected to the motor, a stirring rod connected to the rotating shaft, and multiple groups of first through holes formed in the stirring rod; by setting the acceleration component to cooperate with the main body component, during use, the stirring rod is driven to rotate by the motor to accelerate the flow rate of the concentrated liquid at the concentrated liquid outlet, avoiding the occurrence of blockage. On the other hand, the rapid circulation of the concentrated liquid can reduce the corrosion of the concentrated liquid outlet, solving the problem that when wastewater is input into the evaporation tank, under a vacuum state, the boiling point decreases, the evaporated water vapor forms condensed water and is discharged through the condensation tank, and the concentrated liquid left after the water is evaporated needs to be discharged from the concentrated liquid outlet at the lower end of the evaporation tank. However, at this time, the concentrated liquid is relatively thick and has a slow flow rate, which is easy to cause blockage of the concentrated liquid outlet, and the concentrated liquid has strong corrosiveness and causes great damage to the concentrated liquid outlet.

[0004] In the process of treating wastewater with the help of a low-temperature evaporator, there is a problem that existing low-temperature evaporators such as the above-mentioned one, in order to solve the problem of waste liquid blocking the pipeline, an acceleration component is arranged in the waste liquid pipeline to accelerate the flow efficiency of the waste material in the pipeline. However, because the installation position of the acceleration component is in the vertical area of the waste liquid pipe, when the waste liquid enters the horizontal area of the waste liquid pipe, the waste liquid will still reduce the flow efficiency in the waste liquid pipe due to its own state, and then cause the waste liquid pipe to be blocked again. Summary of the Utility Model

[0010] Preferably, the three-way pipe is communicated with the discharge port of the evaporation tank, and the inner walls of the three-way pipe and the waste liquid pipe are communicated. Through the three-way pipe, the discharge port of the evaporation tank and the waste liquid pipe can be connected, and at the same time, it is convenient for the staff to install the driving structure.

[0011] Preferably, the sealing disk is in a T shape, and the maximum diameter of the sealing disk is larger than the outer diameter of the three-way pipe. Through the sealing disk, the installation end of the three-way pipe can be sealed, so as to ensure the guiding effect of the three-way pipe on the waste.

[0012] Preferably, the threaded feed rod is located on the inner wall of the tee pipe and on the inner wall of the waste liquid pipe.

[0027] Specifically, an installation cavity 615 is formed on the side surface of the sealing disc 612. The threaded feeding rod 614 is rotatably connected to the inner wall of the installation cavity 615. A sealing ring 616 is installed on the inner wall of the installation cavity 615 where the sealing disc 612 is located. The sealing ring 616 is sleeved on the surface of the threaded feeding rod 614. Through the sealing ring 616, the sealing performance of the connection part between the sealing disc 612 and the threaded feeding rod 614 can be increased to reduce the probability of waste liquid leakage.

[0028] Specifically, the tee pipe 611 is communicated with the discharge port of the evaporation tank 1 and the inner wall of the waste liquid pipe 4.

[0029] In this embodiment: Through the tee pipe 611, the discharge port of the evaporation tank 1 and the waste liquid pipe 4 can be connected, and at the same time, it is convenient for the staff to install the driving structure.

[0030] Specifically, the sealing disc 612 is in a T shape, and the maximum diameter of the sealing disc 612 is greater than the outer diameter of the tee pipe 611. Through the sealing disc 612, the installation end of the tee pipe 611 can be sealed, so as to ensure the guiding effect of the tee pipe 611 on the waste.

[0036] Working principle: When the equipment is working, the wastewater is pumped into the evaporation tank 1 through a pipeline. The evaporation pipes work to heat the wastewater, causing the water in the wastewater to turn into water vapor. The water vapor enters the condensation tank 3 through the connecting pipe 2. The condensation tank 3 works to change the state of the water vapor into condensed water. The condensed water is discharged through the drain pipe 5. At the same time, the waste liquid in the evaporation tank 1 is discharged through the waste liquid pipe 4. When the evaporation tank 1 discharges the waste liquid, the servo motor 613 works.

While the connecting turntable 621 is rotating, it cooperates with the inclined guiding groove to reciprocally drive the connecting convex block 623. During the movement of the connecting convex block 623, it cooperates with the bracket to drive the linkage shaft 625. Under the action of the L-shaped bracket 624, the linkage shaft 625 reciprocally drives the top feeding frame 626 up and down. While the top feeding frame 626 is moving, it accelerates the flow rate of the waste liquid in the discharge port of the evaporation tank 1. When the waste liquid flows into the tee pipe 611, the threaded feeding rod 614 located in the tee pipe 611 accelerates the flow rate of the waste liquid in the tee pipe 611 and the waste liquid pipe 4 to improve the discharge efficiency of the waste liquid. By setting the auxiliary component 6, the equipment can accelerate the flow rate of the waste liquid both vertically and horizontally, thereby reducing the problem that when the equipment only accelerates vertically, the flow rate of the waste liquid will still decrease and block when it enters the horizontal area, and further improving the discharge efficiency of the waste liquid of the equipment.
