Description

Technical Field

[0001] This invention belongs to the field of magnesium sulfate production technology, specifically a device for removing impurities from magnesium sulfate solution. Background Technology

[0002] Magnesium sulfate is a magnesium-containing compound, a colorless or white crystal or powder. Adding magnesium sulfate heptahydrate to nickel plating solution can improve the conductivity of the solution and make the plating layer white and soft. In the environmental protection industry, magnesium sulfate heptahydrate is used directly as a wastewater treatment agent or as a raw material for wastewater treatment. It is used for industrial wastewater treatment, and plays a role in coagulation and sedimentation of waste liquids and sewage.

[0003] Currently, magnesium sulfate is mostly produced using potassium chloride byproducts as raw materials, which are mixed with magnesium-containing mother liquor from bromine production in a certain proportion. The mixture is then heated, filtered, impurity removed, and cooled to crystallize, thus producing industrial magnesium sulfate. In existing technologies, the filtration and impurity removal of magnesium sulfate solutions mostly involves passing the solution through a container containing a filter screen. The filter screen intercepts impurities in the solution. However, as the filter screen traps impurities for a long time, they accumulate on one side, easily causing blockage and affecting the subsequent filtration efficiency. Therefore, the filter screen needs to be periodically removed from the container for cleaning. This process interrupts the filtration process, further impacting the filtration efficiency.

[0017] A slider is provided at the end of the support shaft away from the filter cylinder. The slider slides in cooperation with the guide rail. The first limiting seat is connected to the slider through an elastic element, which provides elastic support for the slider.

[0018] As a further improvement of the present invention: the elastic element is a spring or a metal sheet.

[0019] As a further improvement of the present invention: the end of the support shaft away from the filter cylinder is rotatably connected to the slider.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows: In the embodiments of the present invention, when it is necessary to filter and remove impurities from a magnesium sulfate solution, the magnesium sulfate solution can be introduced into the impurity removal chamber. After the magnesium sulfate solution enters the impurity removal chamber, it acts on the upper part of several filter cylinders. At this time, the magnesium sulfate solution passes through the filter cylinders from top to bottom through the filter holes on the filter cylinders and falls to the bottom of the impurity removal chamber. Meanwhile, the impurities in the magnesium sulfate solution are intercepted at the upper part of several filter cylinders, thereby achieving the filtration and removal of impurities from the magnesium sulfate solution. In the above process, the magnesium sulfate solution falling to the bottom of the impurity removal chamber is lifted to the rinsing component by the lifting component, and then output by the rinsing component. At the same time, the driving component drives the rinsing component, the pushing component, and the collecting component to move in a circular motion. During the cycle, several filter cartridges are pushed upwards sequentially, causing them to move upwards in sequence. When a certain group of filter cartridges moves upwards, it separates from the adjacent filter cartridges, creating a gap. At this time, the magnesium sulfate solution output from the rinsing component acts on the filter cartridge, thereby rinsing away the impurities trapped on the upper part of the filter cartridge. The rinsed impurities fall through the gap and enter the collection component, thus cleaning and collecting the impurities. This avoids excessive impurities trapped on the upper part of several filter cartridges, which could lead to filter cartridge blockage, and improves the filtration efficiency of magnesium sulfate solution. Compared with existing technologies, this method can automatically clean and collect impurities on the filter cartridges online when filtering magnesium sulfate solution, thereby improving the filtration efficiency of magnesium sulfate solution.

[0043] Please see Figure 1 , Figure 2 as well as Figure 3 This embodiment provides a magnesium sulfate solution impurity removal device, including an impurity removal chamber 10, a drive assembly 20, filter cylinders 30, a rinsing assembly 40, a pushing assembly 50, a collecting assembly 60, and a lifting assembly 70. Several groups of filter cylinders 30 are arranged in a ring inside the impurity removal chamber 10, with the filter cylinders 30 sequentially attached to each other. Each group of filter cylinders 30 has several evenly distributed filter holes 301 on its cylinder body. The rinsing assembly 40 is positioned above the filter cylinders 30, and the collecting assembly 60 is positioned below the filter cylinders 30. Corresponding to the rinsing assembly 40, the lifting assembly 70 is disposed at the bottom inner side of the impurity removal box 10, and is used to lift the magnesium sulfate solution at the bottom inner side of the impurity removal box 10 to the rinsing assembly 40. The driving assembly 20 is installed on the side wall of the impurity removal box 10, and is used to drive the rinsing assembly 40, the pushing assembly 50 and the collecting assembly 60 to move in a circular motion. The pushing assembly 50 is installed at one end of the collecting assembly 60. When the pushing assembly 50 moves in a circular motion, it can push several filter cylinders 30 upward in sequence, so that several filter cylinders 30 move upward in sequence.

[0044] When it is necessary to filter and remove impurities from a magnesium sulfate solution, the magnesium sulfate solution can be introduced into the impurity removal chamber 10. Once inside the chamber 10, the solution acts on the upper part of several filter cylinders 30. The solution then passes through the filter holes 301 on the filter cylinders 30 from top to bottom and falls to the bottom of the inner side of the chamber 10. Impurities in the solution are trapped at the top of the filter cylinders 30, thus achieving the filtration and removal of impurities. During this process, the lifting component 70 lifts the magnesium sulfate solution that has fallen to the bottom of the chamber 10 to the rinsing component 40, from which it is then output. Simultaneously, the driving component 20 drives the rinsing component 40... The pushing component 50 and the collecting component 60 move in a circular motion. When the pushing component 50 moves in a circular motion, it pushes several filter cylinders 30 upward in sequence, causing the filter cylinders 30 to move upward in sequence. When a certain group of filter cylinders 30 moves upward, the filter cylinder 30 separates from the adjacent filter cylinders 30 and a gap is created. At this time, the magnesium sulfate solution output by the rinsing component 40 acts on the filter cylinder 30, thereby rinsing the impurities intercepted on the upper part of the filter cylinder 30. The rinsed impurities fall through the gap and enter the collection component 60, thereby cleaning and collecting the impurities, avoiding excessive impurities intercepted on the upper part of several filter cylinders 30 and causing the filter cylinders 30 to become clogged, and improving the filtration and impurity removal efficiency of the magnesium sulfate solution.

[0045] Please see Figure 1 as well as Figure 5In one embodiment, each group of filter cartridges 30 is distributed radially along the impurity removal chamber 10. A support shaft 303 is fixedly mounted at one end of each group of filter cartridges 30. A pusher 302 is fixedly mounted on the outside of the support shaft 303. The drive assembly 20 includes a motor 201 and a rotating shaft 202. The motor 201 is fixedly mounted on the top of the impurity removal chamber 10. One end of the rotating shaft 202 is connected to the output end of the motor 201, and the other end extends into the interior of the impurity removal chamber 10 and is supported by several filter cartridges 302. The collection assembly 60, which passes vertically through the center position, includes a collection box 601 located below the plurality of filter cylinders 30 and fixedly connected to the rotating shaft 202. The collection box 601 is radially distributed along the impurity removal box 10. The push assembly 50 includes a support rod 501 and a push rod 502. The support rod 501 is fixedly disposed at one end of the collection box 601, and one end of the push rod 502 is fixedly connected to the support rod 501, while the other end extends to the outer side of the ends of the plurality of filter cylinders 30.

[0046] As the magnesium sulfate solution passes through the filter cylinder 30 from top to bottom through the filter holes 301, the motor 201 drives the rotating shaft 202 to rotate. The rotating shaft 202 drives the collection box 601, support rod 501, and push rod 502 to move in a circular motion. When the push rod 502 moves, it can act on the push rollers 302 at one end of several filter cylinders 30 in sequence, thereby pushing the push rollers 302 and causing several filter cylinders 30 to move upward in sequence. When a group of filter cylinders 30 moves upward, it separates from the adjacent filter cylinders 30. At this time, a separation occurs between the filter cylinder 30 and the adjacent filter cylinders 30. The magnesium sulfate solution, lifted by the lifting component 70 to the rinsing component 40, acts on the filter cylinder 30 to rinse the impurities on the filter cylinder 30, allowing the impurities to pass through the gap and fall into the collection box 601, thus realizing the automatic cleaning and collection of impurities on the upper part of the filter cylinder 30. As the push rod 502 moves in a circular motion, when the push rod 502 separates from the push wheel 302 at one end of a certain group of filter cylinders 30, the filter cylinder 30 moves down and reset under the action of gravity, so as to continue filtering the magnesium sulfate solution that subsequently enters the impurity removal box 10.

[0047] Please see Figure 5 In one embodiment, the collection box 601 has a plurality of evenly distributed through holes 602 on its body.

[0048] When the magnesium sulfate solution output by the rinsing component 40 flushes the debris on the upper part of the filter cartridge 30 into the collection box 601, the magnesium sulfate solution can pass through the through hole 602 and fall back to the bottom of the inner side of the impurity removal box 10, while the debris is intercepted inside the collection box 601, thus achieving smooth collection of the debris. This avoids the situation where as more magnesium sulfate solution enters the collection box 601, the debris overflows from the upper part of the collection box 601 and falls back to the bottom of the inner side of the impurity removal box 10, thereby affecting the filtration and impurity removal effect of the magnesium sulfate solution.

[0049] Please see Figure 5 In one embodiment, vertically distributed guide rails 104 are fixedly arranged on the inner wall of the impurity removal box 10. A first limiting seat 103 is fixedly arranged at the upper end of the guide rail 104, and a second limiting seat 106 is fixedly arranged at the bottom of the guide rail 104. A slider 304 is arranged at the end of the support shaft 303 away from the filter cylinder 30. The slider 304 slides with the guide rail 104. The first limiting seat 103 and the slider 304 are connected by an elastic element 105, which provides elastic support for the slider 304.

[0050] When the filter cartridge 30 filters the magnesium sulfate solution, the elastic element 105 provides elastic support for the slider 304, so that the slider 304 acts on the upper part of the second limiting seat 106. At this time, several filter cartridges 30 are on the same horizontal plane and attached to each other, thereby preventing the debris intercepted on the upper part of the filter cartridges 30 from leaking between adjacent groups of filter cartridges 30. When the push rod 502 acts on the push wheel 302 at one end of a certain group of filter cartridges 30 and pushes the filter cartridge 30 to move upward, the filter cartridge 30 drives the slider 304 to slide upward along the guide rail 104 through the support shaft 303. The elastic element 105 is compressed by force. When the push rod 502 separates from the push wheel 302, the elastic element 105 can push the slider 304 to slide down quickly along the guide rail 104, thereby driving the support shaft 303, push wheel 302 and filter cartridge 30 to move downward quickly, realizing the rapid reset of the filter cartridge 30.

[0051] In one embodiment, the elastic element 105 can be a spring or a metal sheet, and there is no limitation on this.

[0052] In one embodiment, the end of the support shaft 303 away from the filter cylinder 30 is rotatably connected to the slider 304.

[0053] When the push rod 502 acts on a set of push rollers 302 and pushes the corresponding filter cylinder 30 upward, the friction between the push rod 502 and the push roller 302 can drive the push roller 302 to rotate. The push roller 302 drives the support shaft 303 and the filter cylinder 30 to rotate relative to the slider 304. During the rotation of the filter cylinder 30, the flushing action can be combined to improve the cleaning effect of the debris on the filter cylinder 30.

[0054] Please see Figure 1 as well as Figure 4 In one embodiment, the end of the rotating shaft 202 away from the motor 201 extends to the bottom of the inner side of the impurity removal box 10. The rotating shaft 202 has a lifting channel 203 inside, and the lifting assembly 70 communicates with the lifting channel 203. The rinsing assembly 40 includes an arc-shaped cover 401, a spray pipe 402, and a nozzle 403. The spray pipe 402 is located above a plurality of filter cylinders 30 and is fixedly connected to the rotating shaft 202. The spray pipe 402 is radially distributed along the impurity removal box 10. One end of the spray pipe 402 communicates with the lifting channel 203. The arc-shaped cover 401 is fixedly disposed outside the spray pipe 402. A plurality of nozzles 403 are provided, and the plurality of nozzles 403 are fixedly disposed at the bottom of the spray pipe 402 and spaced apart along the length direction of the spray pipe 402.

[0055] As the rotating shaft 202 rotates, driving the collection box 601 and the push rod 502 to move in a circular motion, the rotating shaft 202 can also drive the nozzle 402 and the arc-shaped cover 401 to move in a synchronous circular motion directly above the collection box 601. When the push rod 502 pushes a certain group of filter cartridges 30 upwards, the lifting assembly 70 lifts the magnesium sulfate solution at the bottom of the inner side of the impurity removal box 10 into the lifting channel 203, then into the nozzle 402 through the lifting channel 203, and finally sprays it out through several nozzles 403 to spray the filter cartridges 30. The impurities are rinsed and fall into the collection box 601 through the gaps between the filter cylinders 30, thus collecting the impurities. When the arc-shaped cover 401 moves in a circular motion, the upward-pushing filter cylinders 30 can be covered inside. At this time, the magnesium sulfate solution subsequently introduced into the impurity removal box 10 acts on the arc-shaped outer wall of the arc-shaped cover 401 and is guided by the arc-shaped outer wall of the arc-shaped cover 401 to the upper part of other filter cylinders 30, preventing the magnesium sulfate solution from falling into the bottom of the impurity removal box 10 without filtration, thereby improving the filtration effect of the magnesium sulfate solution.

[0056] Please see Figure 6 as well as Figure 7In one embodiment, a lifting port 204 is provided on the side wall of the rotating shaft 202. The lifting assembly 70 includes a support plate 701, a transmission gear 702, an internal gear ring 703, a drive gear 704, a ring plate 705, and a lifting auger 707. One end of the lifting auger 707 is rotatably connected to the inner bottom wall of the impurity removal box 10, and the other end extends into the lifting channel 203. The ring plate 705 is arranged around the outside of the lifting auger 707, and the inner wall of the ring plate 705 is connected to the lifting auger 707 by several connecting rods 706. 07 Fixed connection, the drive gear 704 is fixedly mounted on the outer wall of the rotating shaft 202, the internal gear ring 703 is fixedly mounted on the inner wall of the ring plate 705, one end of the support plate 701 is fixedly connected to the inner bottom wall of the impurity removal box 10, and the other end extends to the top of the ring plate 705, the transmission gear 702 is rotatably mounted on the bottom of the support plate 701, the transmission gear 702 is located between the drive gear 704 and the internal gear ring 703 and meshes with the drive gear 704 and the internal gear ring 703.

[0057] After the magnesium sulfate solution passes through the filter hole 301 and falls to the bottom of the inner side of the impurity removal box 10, part of the magnesium sulfate solution enters the lifting channel 203 from the lifting port 204. When the rotating shaft 202 rotates, it drives the collection box 601, the top rod 502 and the nozzle 402 to rotate in a circular motion. At the same time, the rotating shaft 202 can also drive the drive gear 704 to rotate. When the drive gear 704 rotates, it drives the transmission gear 702 to rotate through meshing with the transmission gear 702. When the transmission gear 702 rotates, it drives the ring plate 705 to rotate through meshing with the internal gear ring 703. The ring plate 705 drives the lifting auger 707 to rotate through several connecting rods 706. When the lifting auger 707 rotates, it can continuously lift the magnesium sulfate solution that has entered the lifting channel 203 upward, so that the magnesium sulfate solution enters the nozzle 402 from the lifting channel 203 and is then sprayed out by several nozzles 403 to rinse the filter cylinder 30 that is pushed upward, thereby cleaning the filter cylinder 30.

[0058] Please see Figure 1 as well as Figure 2 In one embodiment, the impurity removal box 10 has a liquid inlet 101 at the top and a liquid outlet pipe 102 at the lower part of the side wall of the impurity removal box 10. A valve (not shown in the figure) is provided inside the liquid outlet pipe 102.

[0059] Initially, the valve inside the outlet pipe 102 is closed. During the filtration and impurity removal of the magnesium sulfate solution, as the magnesium sulfate solution enters the impurity removal chamber 10 through the inlet 101, the solution level at the bottom of the chamber gradually rises. When the solution level exceeds the lift port 204, the motor 201 is started. The motor 201 drives the rotating shaft 202 to rotate, which in turn drives the collection box 601, the push rod 502, and the spray nozzle 402 to move in a circular motion, thereby cleaning the impurities on the filter cartridge 30. Meanwhile, the valve inside the outlet pipe 102 is opened, and the magnesium sulfate solution at the bottom of the inner side of the impurity removal box 10 is continuously released through the outlet pipe 102. The magnesium sulfate solution that subsequently enters the impurity removal box 10 continuously falls into the bottom of the inner side of the impurity removal box 10, so that the level of the magnesium sulfate solution at the bottom of the inner side of the impurity removal box 10 is always maintained above the lifting port 204, thereby ensuring that the lifting auger 707 can continuously lift the magnesium sulfate solution into the nozzle 402, so as to continuously clean the impurities on the filter cartridges 30.

[0060] In one embodiment, the filter cartridge 30 may also be a mesh cylinder structure, which is not limited here.

[0061] In this embodiment of the invention, when it is necessary to filter and remove impurities from a magnesium sulfate solution, the magnesium sulfate solution can be introduced into the impurity removal chamber 10. After entering the chamber 10, the magnesium sulfate solution acts on the upper part of several filter cylinders 30. At this time, the magnesium sulfate solution passes through the filter holes 301 on the filter cylinders 30 from top to bottom and falls to the bottom of the inner side of the impurity removal chamber 10. Impurities in the magnesium sulfate solution are intercepted at the upper part of the filter cylinders 30, thereby achieving the filtration and removal of impurities from the magnesium sulfate solution. During this process, the lifting component 70 lifts the magnesium sulfate solution that has fallen to the bottom of the inner side of the impurity removal chamber 10 to the rinsing component 40, and then outputs it from the rinsing component 40. Simultaneously, the driving component 20 drives the rinsing component 40, the pushing component 50, and the collecting component 60 to rotate in a circular motion. During the circular motion of the pushing component 50… A series of filter cartridges 30 are pushed upwards in sequence, causing them to move upwards sequentially. When a certain group of filter cartridges 30 moves upwards, it separates from the adjacent filter cartridges 30, creating a gap. At this time, the magnesium sulfate solution output by the rinsing component 40 acts on the filter cartridge 30, thereby rinsing away the impurities trapped on the upper part of the filter cartridge 30. The rinsed impurities fall through the gap and enter the collection component 60, thus cleaning and collecting the impurities. This avoids excessive impurities trapped on the upper part of the filter cartridges 30, which could cause blockage, and improves the filtration efficiency of the magnesium sulfate solution. Compared with the prior art, when filtering magnesium sulfate solution, the impurities on the filter cartridges 30 can be automatically cleaned and collected online, thereby improving the filtration efficiency of the magnesium sulfate solution.

[0062] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
