Description

Technical Field

[0001] The utility model relates to the field of separation and purification equipment, in particular to a separation and purification equipment for potassium and sodium in MVR output salt. Background Art

[0002] Mechanical Vapor Recompression technology is a highly efficient, energy-saving and environmentally friendly technology, referred to as MVR. The separation of potassium and sodium mostly adopts the method of evaporation and crystallization.

[0003] However, during evaporation and crystallization, when the evaporation and concentration device is passed through steam circulation for evaporation, especially when evaporating a medium containing inorganic salts, crystal scaling will appear on the inner wall of the evaporator. If it is not scraped off in time, a layer of crystal scaling will accumulate inside the evaporator, thereby affecting the normal use of the evaporator. When using a traditional evaporator, the crystal scaling is handled by stopping the machine for cleaning after it accumulates to a certain extent. In this way, when cleaning and scraping off the crystal scaling, the crystal scaling is too thick and difficult to remove, which can easily cause scratches on the evaporator.

[0004] It is now necessary to develop a separation and purification equipment for potassium and sodium in the MVR output salt that can clean the inside of the evaporator in time. Utility Model Content

[0005] In order to overcome the shortcoming that the inside of the evaporator cannot be cleaned in time, the utility model provides a separation and purification device for potassium and sodium in MVR output salt which can clean the inside of the evaporator in time.

A feed port is opened on the outer side of the top of the evaporator, a sealing plug is installed outside the feed port, an MVR steam compressor is installed on the outer side of the top of the evaporator, a collecting frame is slidably installed on the lower side of the inside of the evaporator, a first clamping block is slidably installed on the top side of the outside of the collecting frame, the first clamping block is used to limit the collecting frame, a first motor is installed on the top of the evaporator, a rotating rod is connected to the bottom of the first motor, and a plurality of scraping blocks are evenly installed on the bottom of the rotating rod.

[0007] Preferably, a heat insulating sleeve is also included, and the heat insulating sleeve is installed outside the collection frame.

DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0022] Example 1

[0023] A separation and purification device for potassium and sodium in MVR output salt, such as Figure 1-Figure 6 As shown, it includes an evaporator 1, a feed port 101, a sealing plug 2, an MVR steam compressor 3, a collecting frame 4, a first clamping block 6, a first motor 7, a rotating rod 8 and a scraping block 9. A feed port 101 is opened on the outer side of the top of the evaporator 1, and a sealing plug 2 is installed outside the feed port 101. An MVR steam compressor 3 is installed on the outer side of the top of the evaporator 1. The steam generated by the reaction returns to the evaporator 1 through the MVR steam compressor 3, and the steam is recycled. A collecting frame 4 is slidably installed on the lower side of the inside of the evaporator 1, and a first clamping block 6 is slidably installed on the top side of the outside of the collecting frame 4. The first clamping block 6 is used to limit the collecting frame 4. A first motor 7 is installed on the top of the evaporator 1, and a rotating rod 8 is connected to the bottom of the first motor 7. A plurality of scraping blocks 9 are evenly installed on the bottom of the rotating rod 8, and three scraping blocks 9 are evenly installed, and the inner wall of the evaporator 1 is scraped and cleaned by rotating at the same time.

[0024] When workers need to separate and purify potassium and sodium in the output salt, separation and purification equipment is required, but it is not convenient to clean the evaporator 1 of the equipment, so this equipment can be used to separate and purify potassium and sodium in the output salt. First, open the sealing plug 2, pour the solution into the evaporator 1 through the feed port 101, close the sealing plug 2, and the equipment starts working. Since the steam will float upward during the evaporation and crystallization process, the crystals in the steam will be cooled and precipitated and adhere to the inner wall, so the top inner wall needs to be cleaned, and then turn on the first motor 7. The first motor 7 rotates to drive the rotating rod 8 to rotate, so that the scraper block 9 on the rotating rod 8 rotates, and the scraper block 9 scrapes the inner wall to scrape off the crystals attached to the inner wall.

[0025] Example 2

[0026] On the basis of Example 1, Figure 1-Figure 6As shown, it also includes a heat insulation sleeve 5, a filter screen 10, a second motor 11, a gear set 12, a stirring block 13, a connecting rod 14, a stopper 15, a second clamping block 17, a spring 18 and a discharge pipe 16. The heat insulation sleeve 5 is installed on the outside of the collection frame 4 to facilitate pulling the collection frame 4 to avoid burns. A partition is installed at the bottom of the collection frame 4, and a second motor 11 is installed at the bottom of the partition. The gear set 12 is installed on the top of the second motor 11. A partition is provided on the top of the gear set 12 to prevent crystals from falling into the gear set 12 and affecting the normal operation of the gear set 12. A plurality of stirring blocks 13 are installed through the top of the gear set 12, and the stirring blocks 13 stir the solution to increase the speed. Reaction speed, the end of the gear group 12 away from the second motor 11 is cylindrical, and a filter screen 10 is installed on the top of the cylinder. A discharge pipe 16 is provided at the bottom of the block 15. The cylinder is connected to the discharge pipe 16. The filter screen 10 can prevent crystals from falling into the discharge pipe 16. A connecting rod 14 is slidably connected to the front side of the bottom of the evaporator 1. A stopper 15 is slidably installed at the bottom of the end of the gear group 12 away from the second motor 11. A notch is provided on the block 15. When the notch on the block 15 is aligned with the discharge pipe 16, the solution is discharged through the discharge pipe 16. A second clamping block 17 is installed on the outside of the connecting rod 14, and a spring 18 is sleeved on the second clamping block 17.

[0027] Since there is more solution, the evaporation speed is slow. Therefore, this device can be used when you want to increase the evaporation speed. First, pour the solution through the feed port 101, the device starts working, and then turn on the second motor 11. The rotation of the second motor 11 drives the gear to rotate, so that the stirring block 13 installed on the gear rotates, and the reactants in the container are stirred, so that the solution is fully heated, which can increase the reaction speed.

[0028] The above-mentioned embodiments only express the preferred implementation of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications, improvements and substitutions can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
