Technical Field

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

[0002] Low temperature vacuum evaporator is a special type of evaporator that performs evaporation under low temperature vacuum conditions. The principle of low temperature vacuum evaporator mainly relies on the vacuum pump to extract the air in the container to keep the container in a negative pressure state. Under negative pressure environment, volatile materials can easily diffuse into the container and evaporate by heating through electric heating elements and metal heat transfer surfaces. The evaporated solvent vapor is then collected by condensers, conduits, filters, flame arresters and other equipment, and can be sent to heat source equipment or recycled.

[0003] Salt-containing wastewater contains a large amount of suspended matter, impurities and other insoluble substances. If these substances enter the evaporator directly, it will affect the normal operation and evaporation efficiency of the evaporator, and even damage the evaporator. Therefore, there is an urgent need for a low-temperature vacuum evaporator that can filter impurities at the water inlet. Utility Model Content

[0007] In addition, a preferred structure is that a filter screen is arranged in the middle of the filter assembly, and the filter screen is arranged in multiple layers.

[0008] In addition, a preferred structure is that the diameter of the mounting ring is the same as the diameter of the filter assembly, and the outer side wall of the mounting ring is provided with an external thread.

[0009] In addition, a preferred structure is that the height of the mounting member is greater than the height of the filter assembly, and sub-screw grooves are provided on the inner side walls of the mounting member to correspond to the external threads.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-6 A low-temperature vacuum evaporator for treating saline wastewater comprises a low-temperature vacuum evaporator body 1, a feed channel 2 is installed on the low-temperature vacuum evaporator body 1, a feed hopper 21 is arranged on the top of the feed channel 2, and a detachable filter assembly 4 is assembled inside the feed channel 2. A plurality of installation cavities 3 are vertically opened on the inner wall of the feed channel 2, and installation parts 42 adapted to the installation cavities 3 are fixedly arranged on the outer side wall of the filter assembly 4, and a mounting ring 5 for fixing the filter assembly 4 is installed on the top of the filter assembly 4.

[0022] The low-temperature vacuum evaporator body 1 includes a series of components such as a condenser, and its specific structure and working mode are all existing technologies currently disclosed on the market. They are all common knowledge known to technical personnel in this field, and are not the main technical problems to be solved in this technical solution. Therefore, they are not elaborated in this utility model.

[0023] The filter assembly 4 is provided with a filter screen 41 in the middle, and the filter screen 41 is a multi-layered arrangement. The filter screen 41 can filter the saline wastewater entering the low-temperature vacuum evaporator body 1, and the specific structure of the filter screen 41 is prior art, so it is not described in detail.

[0024] The diameter of the mounting ring 5 is the same as the diameter of the filter assembly 4, and the outer wall of the mounting ring 5 is provided with an external thread 51. By providing the mounting ring 5, the filter assembly 4 can be pressed and thus installed.

[0025] Among them, the height of the mounting member 42 is greater than the height of the filter assembly 4, and the inner side wall of the mounting member 42 is adapted to open a sub-screw groove 52 corresponding to the external thread 51. The inner side wall of the feed channel 2 is adapted to open a female screw groove 53 corresponding to the external thread 51, and the female screw groove 53 is adapted to the sub-screw groove 52. A positioning column 6 is fixed vertically upward at the bottom of a mounting cavity 3 in the feed channel 2, and a positioning cavity 61 is adapted to open on the side mounting member 42 corresponding to the positioning column 6. Through the setting of the positioning column 6 and the positioning cavity 61, the installation position of the filter assembly 4 can be positioned, so that when the mounting member 42 is inserted into the mounting cavity 3, the sub-screw groove 52 and the female screw groove 53 can be adapted and spliced.

[0026] In this embodiment, when the user needs to use the low-temperature vacuum evaporator body 1 to treat saline wastewater, the user only needs to pour the saline wastewater from the feed hopper 21 into the low-temperature vacuum evaporator body 1 for treatment. And the filter assembly 4 installed in the feed channel 2 can filter the saline wastewater entering the low-temperature vacuum evaporator body 1, thereby preventing a large amount of impurities from entering the low-temperature vacuum evaporator body 1 along with the saline wastewater.

[0027] Furthermore, when the user needs to assemble the filter assembly 4, it is only necessary to insert the mounting members 42 on the outside of the filter assembly 4 into the mounting cavity 3 in the feed channel 2. In addition, during the insertion of the mounting members 42, it is necessary to insert a mounting member 42 with a positioning cavity 61 into the mounting cavity 3 with a positioning column 6. This ensures that the filter assembly 4 is installed at a correct angle.

[0028] Furthermore, when the filter assembly 4 is installed, the sub-screw groove 52 on the mounting member 42 and the female screw groove 53 on the inner wall of the feed channel 2 are adapted and spliced ​​together. The user can then rotate the mounting ring 5 through the outer thread 51 on the outside thereof and clamp it on the top of the filter assembly 4, so that the mounting ring 5 can be used to press the filter assembly 4, thereby achieving fixed installation of the filter assembly 4.

[0029] In the utility model, the low-temperature vacuum evaporator body 1 can be used to treat saline wastewater. By setting the mounting cavity 3 and the mounting ring 5, the filter assembly 4 can be installed in the feed channel 2. In this way, the filter assembly 4 can be used to filter and pre-treat the saline wastewater entering the low-temperature vacuum evaporator body 1, thereby preventing a large amount of impurities in the saline wastewater from entering the low-temperature vacuum evaporator body 1, so as to ensure the normal operation of the low-temperature vacuum evaporator body 1.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
