Description

Technical Field

[0001] This invention relates to the field of filter press technology, and in particular to a filter press and filtration method for producing magnetic materials. Background Technology

[0002] A filter press is a mechanical device that uses pressure to extract liquid from a material. It is a commonly used solid-liquid separation device. A filter press can directly extract liquid and water by applying pressure to the raw material in the filter screen.

[0003] Existing filter press equipment for magnetic materials has the following problems: During the production of magnetic materials, the press can quickly remove liquid moisture from the magnetic materials. However, because the magnetic materials themselves are magnetic, there is a repulsive force between them during feeding, which creates voids in the middle of the material pile. Therefore, due to the inherent characteristics of the magnetic materials, voids exist inside the material during feeding. Water easily accumulates in these voids during filtration, resulting in a decrease in filtration efficiency. Existing filter press technology cannot easily solve this problem. Therefore, there is an urgent need for filter presses and filtration methods for magnetic material production to solve the above problems. Summary of the Invention

[0004] Based on the inherent characteristics of magnetic materials, which cause internal voids during feeding, this invention proposes a filter press and a filter pressing method for producing magnetic materials.

Horizontally fixed sliding frames are bolted to the top and bottom of the inner walls on both sides of the main unit housing. Three filtration mechanisms are formed between the six fixed sliding frames at the top and bottom. A feeding mechanism is provided at the top of each filtration mechanism. Each filtration mechanism includes a filter cylinder. A buffer ring is fixed to the top circumference of the filter cylinder. A horizontally arranged cylinder fixing frame is bolted to the inner circumference of the buffer ring. A material handling cylinder is bolted to the bottom of the cylinder fixing frame, and the axis of the material handling cylinder coincides with that of the cylinder fixing frame.

The feeding cylinder is made of soft rubber material.

[0007] Preferably, the displacement mechanism includes a sliding end seat hinged to both ends of a fixed end shaft, and an end seat slider is welded to the bottom of the sliding end seat. The displacement mechanism also includes an end seat groove opened at the top of a fixed slide, and the end seat slider is slidably engaged with the end seat groove. A horizontally arranged transverse lead screw is fixed between the two sides of the fixed slide at the middle position of the end seat groove through a bearing, and the transverse lead screw is threaded and fixed to the internal thread of the end seat slider. A drive motor is fixed to the inner wall of one side of the fixed slide.

[0008] Preferably, the inner circumferential wall of the filter press cylinder is fixed with circumferentially arrayed segmented inner plates by bolts. The outer wall of the segmented inner plates is in contact with and sealed to the material handling cylinder. The outer wall of the material handling cylinder and the inner wall of the filter press cylinder form a closed filter press chamber with the segmented inner plates on both sides. The filter press cylinder has a rectangular slot at the position of the filter press chamber, and an extrusion panel is sealed and fixed at the position of the rectangular slot on the outer wall of the filter press cylinder. The surface layer of the extrusion panel is provided with drainage filter holes.

[0009] Preferably, the material feeding cylinder is provided with a material feeding mechanism inside. The material feeding mechanism includes a lifting screw fixed between the inner wall of the top and the inner wall of the material feeding cylinder by a bearing, and a discharge slot is opened at the bottom of the material feeding cylinder. A drive motor fixed to the top of the lifting screw is fixed to the inner wall of the top of the material feeding cylinder. An electromagnetic sliding box slide rod is fixed between the top and bottom of the inner circumference of the material feeding cylinder by bolts, and an electromagnetic sliding box is slidably engaged with the outer circumference of the electromagnetic sliding box slide rod. An electromagnet is fixed inside the electromagnetic sliding box by bolts.

[0010] Preferably, the outer circumferential wall of the lifting screw is threaded with a horizontally arranged lifting slip ring, and the outer circumferential wall of the lifting slip ring is fixed to the electromagnetic sliding box at the circumferential position by bolts with two horizontally arranged multi-stage sleeve rods.

[0011] Preferably, a lifting and pressing mechanism is provided at the middle position between the top and bottom fixed slides. The lifting and pressing mechanism includes a fixed vertical frame that is fixed between the two fixed slides by bolts. A lifting slider is slidably sleeved at the middle position of the fixed vertical frame. An inner slot is opened at the middle of the top and bottom of the lifting slider, and the inner slot is sleeved with the fixed vertical frame.

[0012] Preferably, lifting grooves are provided on both sides of the fixed vertical frame, and vertically arranged side racks are fixed to the inner wall of the lifting grooves by bolts. Motors are fixed to the inner walls of both sides of the lifting slider by bolts, and a second gear is sleeved and fixed to the output shaft of the motor. The circumference of the second gear meshes with the side rack.

The first gear meshes with the second gear.

[0014] The beneficial effects of this invention are as follows:

[0015] 1. The filter press and filtration method for producing magnetic materials: The lifting slip ring inside the material feeding cylinder drives the lifting screw to rotate through the top drive motor, causing it to move up and down, which in turn causes the electromagnetic sliding box at the circumference to rise and fall. After the electromagnet inside the electromagnetic sliding box conducts electricity, it magnetically attracts the magnetic material at the outer wall of the circumference, and the magnetic material inside the filter press hopper is fed so that the internal gaps are also filled with magnetic material.

[0016] 2. The filter press and filtration method for producing magnetic materials use a top and bottom displacement mechanism to make the filter cylinder stand in a vertical position. The motor fixed at the fixed end of the shaft rotates, causing the filter cylinder to rotate rapidly, which can centrifugally dehydrate the magnetic material at the circumference.

[0017] 3. The filter press and filtration method for producing magnetic materials involves the top of the extrusion panel contacting the extrusion arc claw, with the bottom of the extrusion panel closer to the extrusion arc claw. The gradual descent of the lifting slider causes the extrusion arc claw and extrusion panel to press against each other, thus filtration of the magnetic material in the internal filter hopper. The closer to the bottom, the stronger the pressing effect and the better the filtration result. During the filtration process, the meshing of the first and second gears causes the eccentric flywheel to rotate, which in turn presses one side of the extrusion arc claw via a rotating connecting rod. This reciprocating pressing further enhances the filtration effect between the extrusion arc claw and the extrusion panel. Attached Figure Description

[0037] When using this invention, the steps are as follows:

[0038] Feeding: The magnetic material to be filtered is fed into the inside of the collection hopper 4. The magnetic material is introduced into the inside of the filter cylinder 16 through the feed cylinder 2. The magnetic material is placed in the pressure hopper 18 distributed in a circle. The magnetic material is distributed in a circle by the dividing inner plate 17.

[0039] Material handling: The lifting slip ring 19 inside the material handling cylinder 13 drives the lifting screw 23 to rotate through the top drive motor, causing it to move up and down, which in turn drives the electromagnetic sliding box 21 at the circumference position to rise and fall. After the electromagnet inside the electromagnetic sliding box 21 conducts electricity, it magnetically attracts the magnetic material at the outer wall of the circumference, and also handles the magnetic material inside the filter press hopper 18 so that the internal gaps are also filled with magnetic material.

[0040] Water removal: The displacement mechanism drives the top and bottom transverse screws to rotate and move the sliding end seats 11 at the top and bottom positions respectively. Through the top and bottom displacement mechanisms, the filter press cylinder 16 is made to be in a vertical position. The motor fixed at the fixed end shaft 10 rotates, making the filter press cylinder 16 rotate quickly, which can centrifugally dewater the magnetic material at the circumference.

[0041] Filtration: During the centrifugal process, most of the water in the magnetic material is centrifuged out. During the filtration process, the overall posture of the filtration mechanism is kept tilted by the control of the top and bottom displacement mechanisms. The top position of the extrusion panel 8 on the side of the filter cylinder 16 contacts the extrusion claw 6, and the bottom position of the extrusion panel 8 is closer to the extrusion claw 6. As the lifting slider 7 gradually descends, the extrusion claw 6 and the extrusion panel 8 are squeezed, which filters the magnetic material in the internal filter cylinder 18. The closer to the bottom, the closer the extrusion panel 8 and the extrusion claw 6 are, the stronger the squeezing effect and the better the filtration effect. During the filtration process, the eccentric flywheel 26 is rotated by the meshing of the first gear 27 and the second gear 29. The rotating connecting rod 28 squeezes one side of the extrusion claw 6. The reciprocating squeezing makes the filtration effect of the extrusion claw 6 and the extrusion panel 8 better.

[0042] Discharge: After contact during the filter pressing process, the top and bottom of the displacement mechanism keep the filter press cylinder 16 in a vertical position. The rotation of the lifting screw 23 causes the electromagnetic sliding box 21 at the circumference to move up and down. Through the conduction and de-energization of the internal electromagnet, the magnetic material after filter pressing is loosened. Then, the rotation of the filter press cylinder 16 loosens the magnetic material in the filter press hopper 18. After the rotation stops, the material is discharged through the bottom of the filter press cylinder 16.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

8. A filter press method for producing magnetic materials, utilizing a filter press for producing magnetic materials according to any one of claims 1-7, comprising the following steps: Feeding: The magnetic material to be filtered is fed into the inside of the collection hopper (4). The magnetic material is fed into the inside of the filter cylinder (16) through the feed cylinder (2). The magnetic material is placed in the pressure hopper (18) distributed in a circle. The magnetic material is distributed in a circle by dividing the inner plate (17). Material handling: The lifting slip ring (19) inside the material handling cylinder (13) drives the lifting screw (23) to rotate through the top drive motor, causing it to move up and down, which in turn causes the electromagnetic sliding box (21) at the circumference to rise and fall. After the electromagnet inside the electromagnetic sliding box (21) conducts electricity, it magnetically attracts the magnetic material at the outer wall of the circumference and handles the magnetic material inside the filter press bin (18), so that the internal gaps are also filled with magnetic material. Water removal: The displacement mechanism drives the top and bottom transverse screws to rotate and move the sliding end seats (11) at the top and bottom positions respectively. Through the displacement mechanism at the top and bottom, the filter press cylinder (16) is made to be in a vertical position. The motor fixed at the fixed end shaft (10) rotates, causing the filter press cylinder (16) to rotate rapidly and centrifugally dewater the magnetic material at the circumference position.

During the filtration process, the eccentric flywheel (26) is rotated by the meshing of the first gear (27) and the second gear (29). The extrusion claw (6) is squeezed by the rotating connecting rod (28). The reciprocating squeezing makes the filtration effect of the extrusion claw (6) and the extrusion panel (8) better. Discharge: After contact during the filter pressing process, the filter press cylinder (16) is kept vertical by the movement of the top and bottom of the displacement mechanism. The rotation of the lifting screw (23) causes the electromagnetic sliding box (21) at the circumference to move up and down. The magnetic material after filter pressing is loosened by the conduction and de-energization of the internal electromagnet. Then, the magnetic material in the filter press hopper (18) is loosened by the rotation of the filter press cylinder (16). After the rotation stops, the material is discharged through the bottom of the filter press cylinder (16).
