[0002] Compound fertilizer is a kind of fertilizer that contains two or more of the main nutrients such as nitrogen (N), phosphorus (P), potassium (K), etc. Compound fertilizer has the advantages of high nutrient content, few by-components and good physical properties. It can supply the nutrients needed by crops in a relatively balanced and long-term manner, and improve the effect of fertilization and yield increase. In order to avoid the adverse effects of internal magnetic impurities on the quality and performance of fertilizers, affect the nutrient content and distribution uniformity of fertilizers, and cause damage to crops during the fertilization process, the raw material slurry of compound fertilizers needs to be demagnetized during the processing of compound fertilizers.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention facilitates more thorough adsorption and filtration of iron impurities in the slurry by arranging the coordination of structures such as a spray pipe, a high-pressure water pump, an arc plate, and a magnetic plate, thereby increasing the contact area. The slurry inside the box is sprayed out along the spray pipe by using a high-pressure water pump. Since the spray pipe presents a conical hole shape, when the fluid enters the wider part of the conical bucket, the flow rate slows down, and then accelerates in the narrower part of the conical bucket. Due to the continuity principle of the fluid, the increase in flow rate will lead to a decrease in pressure, and at the outlet of the bucket, due to the sudden increase in the flow channel, the pressure As the slurry becomes wider, the flow rate slows down and the pressure increases accordingly, thereby achieving a pressurization effect and further enhancing the spraying range, so that the slurry is sprayed along the spray pipe, and the sprayed slurry contacts and collides with the arc plate on the top cover to form water mist, which breaks up the slurry and allows the iron in it to fall more evenly on the magnetic plates on both sides for adsorption, solving the problem that the slurry cannot fully contact with the magnetic roller during the adsorption of iron in the slurry by the magnetic roller in the existing magnetic filtration and separation equipment, making it difficult to fully filter the magnetic impurities in the slurry, affecting the iron removal effect, and the like.

[0020] The present invention facilitates the rapid flipping of the magnetic plate by setting up the cooperation of structures such as the driving component, the mounting plate and the magnetic plate. The motor is used to drive the connecting rod to rotate, thereby driving the two worm gears on the surface to rotate synchronously. Since the two worm gears are arranged in opposite directions, the two worm gears and the driving rod can be driven to flip in opposite directions, so that the magnetic plates on both sides of the mounting plate are quickly flipped to ensure the adsorption effect. During the flipping process, the driving rod drives the first crank to rotate, thereby driving the second crank to rotate synchronously. Since the driving rods on both sides rotate in opposite directions, the collection boxes on both sides can be driven to move toward each other, and the boxes are kept away from each other during the rotation process to avoid affecting the rotation of the mounting plate. After the rotation is completed, the two boxes are close to each other for resetting, which solves the problem that the magnetism of the magnetic plate is reduced due to long-term use, thereby affecting the magnetic attraction effect.

[0021] The present invention facilitates the rapid cleaning of the used magnetic plate by arranging the cooperation of the electric push rod scraper and the guide plate and other structures. The electric push rod is used to drive the scraper to slide along the bottom magnetic plate to scrape off the iron on the surface of the magnetic plate. The scraped iron contains water stains, which can flow along the guide plate into the collection box for collection, thereby achieving the cleaning effect, facilitating reuse and improving resource utilization.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figures 1 to 8 As shown, the present invention provides a slurry magnetic filtering device for compound fertilizer processing, comprising a box body 1, a spray box 11 is fixedly connected to the top center of the box body 1, a water collection tank 111 is provided on the top of the spray box 11, the spray box 11 is connected to the box body 1, the interior of the box body 1 is filled with slurry, a mounting box 2 is fixedly connected to the top of the box body 1, a top cover 21 is fixedly connected to the top of the mounting box 2, the top cover 21 is composed of two inclined plates, and the two inclined plates are inclined to both sides to present a triangular shape, a plurality of arc plates 211 are fixedly connected to the inner wall of the top cover 21, and the arc plates 211 are in contact with the sprayed slurry, a feed pipe 12 is fixedly connected to the side of the box body 1, the feed pipe 12 is L-shaped, a hopper 121 is fixedly arranged on the top of the feed pipe 12, a discharge pipe 13 is fixedly connected to the side of the box body 1 away from the feed pipe 12, and the discharge pipe 13 is fixedly connected to the discharge pipe 13. A control valve 131 is provided on the tube 13, the top of the spray box 11 is designed in an arc surface, with convex ends and a concave center; a spray mechanism 3 is provided inside the spray box 11, mounting plates 4 are provided on both symmetrical sides of the spray box 11, the two mounting plates 4 are inclined and funnel-shaped with the top surface of the spray box 11, the top and bottom of the mounting plates 4 are fixedly connected with magnetic plates 41 for adsorbing iron, and a driving assembly 44 for driving the mounting plates 4 to perform horizontal flipping is provided inside the box body 1; the spray mechanism 3 includes a spray pipe 31, the surface of the spray pipe 31 is provided with a plurality of through holes 311 distributed in a circular array, the cross-sections of the through holes 311 and the spray pipe 31 are both larger at the top and smaller at the bottom, a high-pressure water pump 32 is provided at the bottom of the spray pipe 31, and the high-pressure water pump 32 is fixedly connected to the inner wall at the center of the spray box 11.

[0033] The above scheme is adopted: the slurry to be filtered is poured into the interior of the box body 1 along the feed pipe 12 through the hopper 121, and the slurry inside the box body 1 is sprayed out along the spray pipe 31 by using the high-pressure water pump 32. Since the spray pipe 31 is in the shape of a conical hole, the pressure is increased by changing the flow speed and direction of the fluid. When the fluid enters the wider part of the conical hopper, the flow rate slows down, and then accelerates in the narrower part of the conical hopper. Due to the continuity principle of the fluid, the increase in flow rate will lead to a decrease in pressure. At the outlet of the hopper, the flow channel suddenly widens, the flow rate slows down, and the pressure increases with The increase in pressure can achieve a boosting effect, further enhancing the spraying range, so that the slurry is sprayed along the spray pipe 31, and the sprayed slurry contacts and collides with the arc plate 211 on the top cover 21 to form water mist, which breaks up the slurry and allows the iron therein to fall more evenly on the magnetic plates 41 on both sides for adsorption. The adsorbed slurry falls into the interior of the box body 1 along the water trough 111, thereby reciprocating operation to make the filtration more thorough, and finally the filtered slurry is discharged along the discharge pipe 13 by opening the control valve 131, thereby achieving magnetic filtration of the slurry.

[0034] like Figure 2 As shown, the driving assembly 44 includes two driving rods 441, the two driving rods 441 are fixedly connected to the centers of the two mounting plates 4, one end of the two driving rods 441 is fixedly connected to a worm wheel 442, the two worm wheels 442 are meshed with a worm 443, the centers of the two worm wheels 443 are fixedly connected to a connecting rod 444, the connecting rod 444 runs through the box body 1 and is rotatably connected to both sides of the box body 1, one end of the connecting rod 444 is fixedly provided with a motor 445, the motor 445 is fixedly connected to the box body 1, and the two worm wheels 443 are arranged in opposite directions to drive the two The worm gears 442 rotate in opposite directions, and the top of the box body 1 is located on both sides of the spray box 11 and is fixedly connected to two symmetrical slideways 14. Collection boxes 42 are slidably arranged inside the two slideways 14. A cleaning assembly 43 for scraping iron filings on the surface of the magnetic plate 41 is arranged inside the collection box 42. The two collection boxes 42 are hinged with a second crank 422 on one side away from the worm gear 442, and the two second cranks 422 are hinged with a first crank 421 on one end away from the collection box 42. The first crank 421 is hinged to the side of the driving rod 441 away from the worm gear 442.

[0035] The above scheme is adopted: by using the driving component 44 to drive the two mounting plates 4 to flip 180°, when one side of the magnetic plate 41 has been used for a long time, in order to avoid the problem of its magnetism being reduced and affecting the magnetic attraction effect, the motor 445 can be used to drive the connecting rod 444 to rotate, thereby driving the two worm gears 443 on the surface to rotate synchronously. Since the two worm gears 443 are arranged in opposite directions, the two worm gears 443 and the driving rod 441 can be driven to flip 180° in the opposite direction, and the magnetic plates 41 on both sides of the mounting plate 4 are quickly flipped to ensure the adsorption effect. During the flipping process, the driving rod 441 drives the first crank 421 to rotate, thereby driving the second crank 422 to rotate synchronously. Since the driving rods 441 on both sides rotate in opposite directions, the collection boxes 42 on both sides can be driven to move toward each other, and they are kept away from each other during the rotation process to avoid affecting the rotation of the mounting plate 4. After the rotation is completed, the two are close to each other for reset, thereby completing the entire adjustment. The flipped magnetic plate 41 is cleaned by using the cleaning component 43 for subsequent use.

[0036] like Figure 5 As shown, the cleaning assembly 43 includes an electric push rod 431, which is fixedly connected to the side wall of the collection box 42. The end of the electric push rod 431 away from the inner wall of the collection box 42 is fixedly connected to a scraper 432. The top of the scraper 432 and the magnetic plate 41 are inclined at an angle to the box body 1 and are in sliding contact with the magnetic plate 41. The side of the scraper 432 away from the electric push rod 431 is inclined and fixedly connected to a guide plate 4321.

[0037] The above scheme is adopted: by using the electric push rod 431 to drive the scraper 432 to slide along the bottom magnetic plate 41, the iron on the surface of the magnetic plate 41 is scraped off. The scraped iron contains water stains, which can flow into the collection box 42 along the guide plate 4321 for collection, thereby achieving the cleaning effect, facilitating reuse, and improving resource utilization.

[0038] The working principle and use process of the present invention are as follows: when using the device, the slurry to be filtered is poured into the interior of the box body 1 through the hopper 121, and the slurry in the box body 1 is sprayed out along the spray pipe 31 by the high-pressure water pump 32, so as to further enhance the spraying range, so that the slurry is sprayed out along the spray pipe 31, and the sprayed slurry contacts and collides with the arc plate 211 on the top cover 21 to form water mist, which breaks up the slurry, so that the iron therein can fall more evenly on the magnetic plates 41 on both sides for adsorption, and the adsorbed slurry falls into the interior of the box body 1 along the water trough 111. In order to avoid the problem of reduced magnetism of the magnetic plate 41 after long-term use, the motor 44 is used. 5 drives the connecting rod 444 to rotate, and then drives the two worms 443 on the surface to rotate synchronously. Since the two worms 443 are arranged in opposite directions, the two worms 443 and the driving rod 441 can be driven to flip 180 degrees in the opposite direction, and the magnetic plates 41 on both sides of the mounting plate 4 are quickly flipped to ensure the adsorption effect. The flipped magnetic plates 41 drive the scraper 432 to slide along the bottom magnetic plate 41 by the electric push rod 431 to scrape off the iron on the surface of the magnetic plate 41, thereby achieving a cleaning effect and facilitating its reuse. Finally, the slurry after filtration is discharged along the discharge pipe 13 by opening the control valve 131, thereby achieving magnetic filtration of the slurry.
