Description

Technical Field

[0001] This utility model relates to the field of magnesium sulfate heptahydrate preparation technology, and in particular to a filtration device for producing magnesium sulfate heptahydrate. Background Technology

[0002] Magnesite flotation tailings yield a significant amount of magnesium carbonate. Magnesium sulfate heptahydrate can be produced from this magnesium carbonate through processes such as dissolution, filtration, evaporation, concentration, and crystallization. Filtration is a crucial step, removing insoluble impurities such as silt and ore from the magnesium carbonate solution. Existing filtration devices use filter cloths; however, after a period of use, insoluble impurities accumulate on the filter cloth, causing blockages. This requires manual removal and cleaning, which is cumbersome. Therefore, there is an urgent need to develop a filtration device with a self-cleaning function for producing magnesium sulfate heptahydrate, offering greater convenience and overcoming current shortcomings to meet specific needs. Utility Model Content

[0003] The purpose of this invention is to provide a filtration device for producing magnesium sulfate heptahydrate, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A filtration device for producing magnesium sulfate heptahydrate includes a filter box, baffles, an auxiliary rinsing mechanism, and a self-cleaning filtration mechanism. The filter box has an inlet at its upper end and an outlet at its lower end. The self-cleaning filtration mechanism includes a support shell, a connecting shell, an ultrasonic vibrator, filter cloth, and water-permeable holes. Two support shells are fixed inside the filter box, and a filter cloth is fixed to the upper side of each support shell. The support shells are inclined with the left side higher than the right. The two support shells are fixed and connected by the connecting shell. Both the support shells and the connecting shell are filled with water. An ultrasonic vibrator is installed on the connecting shell and inserted therein. The supporting shell is provided with multiple water-permeable holes. The auxiliary flushing mechanism includes: a main tube, nozzles, a booster pump, and a conduit. The main tube is rotatably connected to the filter box. Multiple nozzles are installed on the main tube. The main tube passes through a supporting shell and is rotatably connected to the supporting shell. The booster pump is fixed on the filter box. The outlet of the booster pump is fixedly connected to a conduit. The upper end of the main tube is inserted into the conduit and rotatably connected to it. The filter box is equipped with a rotating mechanism for driving the main tube to rotate.

[0006] Preferably, the filter box is provided with two waste discharge channels, each of which is located at the lower right end of a support shell, and the filter box is detachably installed with a baffle for blocking the waste discharge channel by screws.

[0007] Preferably, a sealing strip is fixed on the baffle, and the sealing strip is used to fit against the outer wall of the filter box.

[0008] Preferably, the angle between the support shell and the horizontal plane is 20°.

[0009] Preferably, the rotating mechanism includes a drive motor, a first gear, and a second gear. The drive motor is fixed to the filter box, and the first gear is fixed on the output shaft of the drive motor. A second gear is provided on one side of the first gear to mesh with it, and the second gear is fixed to the main tube.

[0010] The beneficial effects of this utility model are as follows: This filtration device for producing magnesium sulfate heptahydrate involves adding the raw material solution through the inlet. The solution undergoes double filtration through two filter cloths, effectively removing insoluble impurities. The filtered solution is then discharged from the outlet. Furthermore, the support shell is tilted to the left and right to allow impurities accumulated on the filter cloth to slide downwards and to the right. After a period of use, the filter cloth is cleaned. During cleaning, the baffle is removed, and an ultrasonic vibrator is activated to vibrate the support shell and the water inside the connecting shell. The support shell transmits the vibration to the filter cloth, causing the accumulated impurities to slide downwards. Simultaneously, a booster pump delivers high-pressure water to the main pipe, which sprays water through nozzles to rinse the filter cloth. A drive motor rotates the first and second gears, which in turn rotate the main pipe and nozzles, ensuring more thorough rinsing of the filter cloth. Impurities on the filter cloth are discharged from the waste discharge tank with the water flow. In summary, this utility model features double filtration, resulting in better performance and a self-cleaning function for the filter cloth, making it more convenient to use.

The filter box 1 has an inlet 101 at its upper end and an outlet 102 at its lower end. Material enters through the inlet 101 and exits through the outlet 102. The self-cleaning filtration mechanism 5 includes a support shell 501, a connecting shell 502, an ultrasonic vibrator 503, a filter cloth 504, and water-permeable holes 505. Two support shells 501 are fixed inside the filter box 1, and a filter cloth 504 is fixed to the upper side of each support shell 501. The filter box 1 is inclined from left to right, with the angle between the support shell 501 and the horizontal plane being 20°, so that impurities accumulated on the filter cloth 504 can slide down to the lower right. The two support shells 501 are fixed and connected by a connecting shell 502. Both the support shell 501 and the connecting shell 502 are filled with water. An ultrasonic vibrator 503 is installed inside the connecting shell 502. The support shell 501 is provided with multiple water permeable holes 505. The water permeable holes 505 are not connected to the inside of the support shell 501, that is, water inside the support shell 501 will not flow out through the water permeable holes 505. The filter box 1 is provided with two waste discharge troughs 103. All 103 are located at the lower right end of a support shell 501. A baffle 2 for blocking the waste discharge trough 103 is detachably installed on the filter box 1 by screws. A sealing strip 201 is fixed on the baffle 2, and the sealing strip 201 is used to fit against the outer wall of the filter box 1. The auxiliary flushing mechanism 3 includes: a main tube 301, nozzles 302, a booster pump 303, and a conduit 304. The main tube 301 is rotatably connected to the filter box 1. Multiple nozzles 302 are installed on the main tube 301. The main tube 301 passes through a support shell 501 and is rotatably connected to the support shell 501. The support shell 501 is provided with a baffle for blocking the waste discharge trough 103. The main tube 301 passes through a hole that is not connected to the interior of the support shell 501. A sealing ring (not shown in the figure) is provided at the joint between the main tube 301 and the support shell 501 to prevent external water from seeping in. The booster pump 303 is fixed on the filter box 1 and is connected to an external water source through a pipe. The outlet of the booster pump 303 is fixedly connected to a conduit 304. The upper end of the main tube 301 is inserted into the conduit 304 and rotatably connected to it. A sealing ring (not shown in the figure) is provided at the joint between the main tube 301 and the conduit 304 to prevent water leakage. A rotating mechanism 4 is installed on the filter box 1 to drive the main tube 301 to rotate.

[0023] The rotating mechanism 4 includes a drive motor 401, a first gear 402, and a second gear 403. The drive motor 401 is fixed to the filter box 1. The first gear 402 is fixed on the output shaft of the drive motor 401. A second gear 403 meshes with the first gear 402 on one side. The second gear 403 is fixed to the main tube 301. In use, the drive motor 401 drives the first gear 402 and the second gear 403 to rotate. The second gear 403 drives the main tube 301 and the nozzle 302 to rotate, so that the nozzle 302 can rinse the filter cloth 504 more thoroughly.

[0024] The switches for booster pump 303, drive motor 401, and ultrasonic vibrator 503 are all mounted on filter box 1 (not shown in the figure).

[0025] Working Principle: This filtration device for producing magnesium sulfate heptahydrate involves adding the raw solution through the inlet 101. The solution undergoes double filtration through two filter cloths 504 to thoroughly remove insoluble impurities. The filtered solution is then discharged through the outlet 102. The support shell 501 is tilted to the left, allowing impurities accumulated on the filter cloths 504 to slide and accumulate to the lower right. After a period of use, the filter cloths 504 are cleaned. During cleaning, the baffle 2 is removed, and the ultrasonic vibrator 503 is activated to vibrate the water inside the support shell 501 and the connecting shell 502. The support shell 501 transmits vibration to the filter cloth 504, causing the impurities accumulated on the filter cloth 504 to slide downwards. At the same time, the booster pump 303 delivers high-pressure water to the main tube 301, and the water is sprayed out through the nozzle 302 to rinse the filter cloth 504. The drive motor 401 drives the first gear 402 and the second gear 403 to rotate. The second gear 403 drives the main tube 301 and the nozzle 302 to rotate, so that the nozzle 302 rinses the filter cloth 504 more thoroughly. The impurities on the filter cloth 504 are discharged from the waste discharge tank 103 with the water flow.
