Description

Technical Field

[0001] This utility model relates to the field of phosphate rock processing technology, and in particular to a multi-stage filtration and purification device for phosphate rock. Background Technology

[0002] Phosphate rock filtration and purification equipment is a multi-separation device designed for phosphate rock. It uses chemical reagent reactions to enrich the useful components and efficiently remove impurities from the phosphate rock, so as to meet the purity requirements of raw materials in subsequent phosphate chemical production.

[0003] Most existing filtration and purification devices directly put the material into chemical reagents for reaction and extraction. However, some substances can be directly removed. If all chemical treatment is used, it will lead to excessive use of chemical reagents, resulting in high costs. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of existing technologies and propose a multi-stage filtration and purification device for phosphate rock. The technical solution adopted by this utility model is as follows:

A screw feeder is installed on the left side of the housing assembly, and a filtration and purification assembly is installed on the left side of the screw feeder. The filtration and purification assembly includes a housing, a first outlet, a second outlet, an inclined filter plate, a second motor, a rotating rod, a magnetic mesh plate, a baffle plate, a lifting plate, and an electromagnet. The first outlet and the second outlet are installed sequentially from top to bottom on the left side of the housing. An inclined filter plate is installed inside the housing, and a second motor is installed on the top of the housing. The rotating end of the second motor is connected to a rotating rod, and the lower end of the rotating rod is connected to a magnetic mesh plate. A baffle plate is installed above one side of the magnetic mesh plate, and a lifting plate is installed below the magnetic mesh plate. An electromagnet is installed below the lifting plate.

[0006] As an improvement, the housing assembly includes a housing, an inlet, and an outlet, with the inlet installed at the upper front of the housing and the outlet installed on the right side of the housing.

[0007] As an improvement, a power assembly is installed at the lower end of the interior of the housing assembly, and an upper spray assembly is installed at the upper end of the power assembly. A discharge auxiliary assembly is installed at the upper end of the interior of the housing assembly.

[0008] As an improvement, the discharge auxiliary component includes a lifting cylinder, a traction rod, a rotating connector, and a filter screen. The lower end of the lifting cylinder is connected to the traction rod, the lower end of the traction rod is connected to the rotating connector, and the lower end of the rotating connector is connected to the filter screen.

[0009] As an improvement, the power assembly includes a support frame, a first motor, a threaded rod, a carbon fiber auxiliary sealing block, and a piston plate. The first motor is mounted on the right side of the support frame, and the rotating end of the first motor is connected to the threaded rod.

[0010] As an improvement, the upper spray assembly includes a partition plate, an inlet pipe, a first one-way valve, an outlet pipe, a second one-way valve, a connecting plate, and a nozzle. The partition plate is sequentially connected to the outlet pipe and the inlet pipe from the middle to the left and right sides.

The upper end of the connecting plate has a nozzle.

[0011] The beneficial effects of this utility model are as follows:

[0012] This utility model is based on a multi-stage filtration and purification device for phosphate rock. During operation, an electromagnet imparts magnetism to the magnetic mesh plate, thereby performing primary purification on the material passing through the magnetic mesh plate and screening out the iron ore in the mineral, thus reducing the consumption of chemical reagents during subsequent chemical purification. A second motor drives the magnetic mesh plate to rotate continuously, thereby scraping off the iron ore adsorbed on the magnetic mesh plate, thus facilitating the continuous operation of the magnetic mesh plate.

[0013] This invention utilizes the reciprocating motion of the piston plate to draw liquid into the spacer below the inlet pipe, then transports the liquid through the outlet pipe to the connecting plate, where it is sprayed out from the nozzle. This impacts the material on the filter screen, facilitating full contact between the liquid and the material and promoting efficient reaction. Simultaneously, the impact causes the material to tumble, altering the contact surface between the material and the liquid, allowing for a more thorough reaction and optimizing the purification effect.

[0018] To make the content of this utility model easier to understand, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0019] like Figure 1 and Figure 3 As shown, the outer casing assembly 1 has a screw feeder 5 on its left side, and a filter and purification assembly 6 is installed on the left side of the screw feeder 5. The filter and purification assembly 6 includes a housing 601, a first outlet 602, a second outlet 603, an inclined filter plate 604, a second motor 605, a rotating rod 606, a magnetic mesh plate 607, a baffle plate 608, a lifting plate 609, and an electromagnet 610. The first outlet is installed sequentially from top to bottom on the left side of the housing 601. The housing 601 has an inlet 602 and a second outlet 603. An inclined filter plate 604 is installed inside the housing 601. A second motor 605 is installed on the top of the housing 601. A rotating rod 606 is connected to the rotating end of the second motor 605. A magnetic mesh plate 607 is connected to the lower end of the rotating rod 606. A baffle plate 608 is provided on the upper side of one side of the magnetic mesh plate 607. A lifting plate 609 is provided below the magnetic mesh plate 607. An electromagnet 610 is installed below the lifting plate 609.

[0020] During operation, the electromagnet 610 imparts magnetism to the magnetic mesh plate 607, thereby performing primary purification on the material passing through the magnetic mesh plate 607, screening out the iron ore in the minerals, thus reducing the consumption of chemical reagents during subsequent chemical purification. The second motor 605 drives the magnetic mesh plate 607 to rotate continuously, thereby scraping off the iron ore adsorbed on the magnetic mesh plate 607, thus facilitating the continuous operation of the magnetic mesh plate 607.

[0021] like Figure 1 As shown, the outer casing assembly 1 includes a casing 101, a feed inlet 102 and a discharge outlet 103, with the feed inlet 102 installed at the front of the upper end of the casing 101 and the discharge outlet 103 installed on the right side of the casing 101.

[0022] like Figure 1 and Figure 2 As shown, a power assembly 3 is installed at the lower end of the interior of the outer shell assembly 1, and an upper spray assembly 4 is installed at the upper end of the power assembly 3. A discharge auxiliary assembly 2 is installed at the upper end of the interior of the outer shell assembly 1.

[0023] like Figure 2 As shown, the discharge auxiliary component 2 includes a lifting cylinder 201, a traction rod 202, a rotating connector 203, and a filter screen 204. The lower end of the lifting cylinder 201 is connected to the traction rod 202, the lower end of the traction rod 202 is connected to the rotating connector 203, and the lower end of the rotating connector 203 is connected to the filter screen 204.

[0024] like Figure 2 As shown, the power assembly 3 includes a support frame 301, a first motor 302, a threaded rod 303, a carbon fiber auxiliary sealing block 304, and a piston plate 305. The first motor 302 is installed on the right side of the support frame 301. The rotating end of the first motor 302 is connected to the threaded rod 303. The carbon fiber auxiliary sealing block 304 and the piston plate 305 are installed on the outside of the threaded rod 303 from right to left.

[0025] The carbon fiber auxiliary sealing block 304 will seal the connection between the threaded rod 303 and the housing 101, preventing concentrated sulfuric acid from leaking out.

[0026] like Figure 2 As shown, the upper spray assembly 4 includes a partition plate 401, an inlet pipe 402, a first one-way valve 403, an outlet pipe 404, a second one-way valve 405, a connecting plate 406, and a nozzle 407. The partition plate 401 is sequentially connected to the outlet pipe 404 and the inlet pipe 402 from the middle to the left and right sides. The first one-way valve 403 is installed at the lower end of the inlet pipe 402, and the second one-way valve 405 is installed at the lower end of the outlet pipe 404. The upper end of the outlet pipe 404 is connected to the connecting plate 406, and the nozzle 407 is opened at the upper end of the connecting plate 406.

[0027] The reciprocating motion of the piston plate 305 draws liquid into the spacer below the partition plate 401 through the inlet pipe 402, and then transports the liquid through the outlet pipe 404 to the connecting plate 406, where it is sprayed out from the nozzle 407. This impacts the material on the filter screen 204, facilitating full contact between the liquid and the material and promoting the reaction of the equipment. Simultaneously, the impact causes the material to tumble, changing the contact surface between the material and the liquid, allowing the liquid to fully react with the material and achieving the best purification effect.

[0028] During use, firstly, a sufficient amount of concentrated sulfuric acid is added to the inside of the housing 101 through the feed inlet 102. Then, the crushed phosphate rock is added to the housing 601 through the feed inlet on the housing 601. At this time, the electromagnet 610 will work and will transmit the magnetism through the lifting plate 609 to the magnetic mesh plate 607, making the magnetic mesh plate 607 magnetic. When the phosphate rock passes through the magnetic mesh plate 607, the magnetism will attract the iron ore in the phosphate rock. Then, the second motor 605 drives the rotating rod 606 to rotate, thereby causing the magnetic mesh plate 607 to rotate. At this time, the iron ore attracted on the magnetic mesh plate 607 will be blocked by the baffle plate 608 and accumulate at the first outlet 602. When the accumulation reaches a certain level, the iron ore will be discharged from the first outlet 602. The phosphate rock without iron ore will continue to fall onto the inclined filter plate 604 for filtration, thereby filtering out larger particles of mud and other impurities. The removed impurities will be discharged from the second outlet 603.

[0029] After two purification processes, the phosphate rock falls below the housing 601. At this time, the screw conveyor 5 is in operation, lifting the phosphate rock above the housing 101, causing it to fall onto the filter screen 204 and react with concentrated sulfuric acid. Simultaneously, the first motor 302 is in operation, driving the threaded rod 303 to rotate, causing the piston plate 305 to move. During the movement of the piston plate 305, the inlet pipe 402 draws concentrated sulfuric acid from the partition plate 401 to one side of the piston plate 305, while the other side of the piston plate 305 squeezes the concentrated sulfuric acid below the partition plate 401, forcing it out of the outlet pipe 404. The phosphate rock is pressed into the connecting plate 406 and sprayed out from the nozzle 407, thus impacting the phosphate rock on the filter screen 204, facilitating the contact reaction between the phosphate rock and concentrated sulfuric acid. After the equipment has been working for a period of time, the lifting cylinder 201 can lift the traction rod 202, thereby causing the filter screen 204 to move the reacted phosphate rock residue upwards and remove it from the notch on the shell 101. At the same time, the reacted liquid can be discharged through the discharge port 103 for collection and phosphorus extraction. When the discharge port 103 is working, the piston plate 305 will continue to work, thereby discharging the liquid under the partition plate 401.

[0030] The above are merely preferred embodiments of this utility model patent and are not intended to limit this utility model patent. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
