Description

Technical Field

[0001] The utility model relates to the technical field of magnetic separators, in particular to a material collecting structure at a discharge port of a magnetic separator. Background Art

[0002] A magnetic separator, also known as magnetic separation equipment, is a mechanical device that uses magnetic properties to separate magnetic materials from other materials. It is primarily used in the production and screening of magnetic minerals such as magnetite, as well as to remove magnetic impurities from various materials to improve product quality. A wet magnetic separator, also known as a water-washing magnetic separator, separates magnetic and non-magnetic materials by utilizing the different magnetic properties of these materials in a magnetic field. It is classified as mineral processing equipment and is one of the mainstream high-strength magnetic separators. A wet magnetic separator primarily consists of a cylinder, brush roller, magnetic system, tank, transmission, and electromagnet. The cylinder is welded from 2-3 mm thick stainless steel sheets, with end caps made of cast aluminum or workpieces, connected to the cylinder with stainless steel screws. The magnetic system utilizes high-quality ferrite or a composite with rare earth magnets to ensure a strong magnetic field.

[0003] The material screened by the wet magnetic separator is discharged through the discharge port. The discharged material has a high water content and is easy to stick to the inside of the equipment, resulting in unstable equipment operation and reduced production efficiency. The material sticking to the inside of the equipment will increase equipment wear and shorten the service life of the equipment. Therefore, a material collection structure for the discharge port of a magnetic separator is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a material collecting structure for a discharge port of a magnetic separator, so as to solve the problem of high water content of the discharged material in the prior art.

[0005] The conveyor belt conveyor is provided with a collecting box, and a collecting box is provided with a collecting box.

[0006] Preferably, a positioning bracket is provided on the reciprocating push rod, and the reciprocating push rod is fixed to the extrusion tube through the positioning bracket. The reciprocating push rod can push the piston pressure plate to move back and forth.

[0007] Preferably, the piston pressing plate is provided with an installation notch, and the filter is installed on the piston pressing plate through the installation notch, and the filter can filter out moisture in the material.

[0008] Preferably, the extrusion tube is connected to the bottom of the collecting funnel through the feed tube, the piston pressure plate is movably installed in the extrusion tube through a reciprocating push rod, and the shielding piece is movably installed in the extrusion tube through the piston pressure plate, and the shielding piece can block the feed tube.

[0009] Preferably, the sealing plugging cover is provided with connecting legs, and the sealing plugging cover is connected to the telescopic rod via the connecting legs, and the telescopic rod can drive the sealing plugging cover to move forward and backward.

[0010] Preferably, a movable hole is provided at the front end of the positioning sleeve, and the telescopic rod extends out of the positioning sleeve through the movable hole, and the telescopic rod can slide in the positioning sleeve.

[0011] Preferably, one end of the return spring is connected to the armature slider, and the other end of the return spring is connected to the bottom of the positioning sleeve. One end of the telescopic rod is fixed to the armature slider, and the other end of the telescopic rod is fixed to the connecting leg. The return spring provides elastic force for the armature slider, so that the armature slider has a tendency to move forward.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. In this application, the reciprocating push rod drives the piston plate forward. This forward movement squeezes the material, allowing moisture within it to be discharged through the filter screen, thereby reducing the moisture content of the material and ensuring stable operation of the equipment. The shielding plate follows the forward and backward movement of the piston plate, thereby blocking the feed pipe and preventing material from entering the extrusion pipe.

[0014] 2. In this application, turning off the electromagnet releases the armature slider. The return spring then pushes the armature slider forward, which in turn drives the telescopic rod forward. This in turn drives the sealing cover forward, allowing the cover to move away from the extrusion tube, facilitating material discharge. Activating the electromagnet attracts the armature slider, causing the sealing cover to block the front end of the extrusion tube, facilitating material extrusion. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0021] like Figure 1 and Figure 2 As shown, the utility model provides a technical solution for the material collection structure of the discharge port of a magnetic separator, including an equipment bracket 1, a screening trough body 2 is fixedly installed on the equipment bracket 1, a magnetic separation roller 3 is provided in the screening trough body 2, a driving motor 4 is fixedly installed on one side of the screening trough body 2, a collecting funnel 5 is fixedly installed on the screening trough body 2, an extrusion mechanism 6 is installed on the collecting funnel 5, and a sealing mechanism 7 is provided at the end of the extrusion tube 603. Through the coordinated use of the extrusion mechanism 6 and the sealing mechanism 7, the material can be squeezed to dehydrate the material and reduce the water content of the material.

[0022] like Figure 2 and Figure 3As shown, the extrusion mechanism 6 includes a feed pipe 605 fixedly mounted on the end of the collecting funnel 5, an extrusion tube 603 is fixedly mounted on the feed pipe 605, a reciprocating push rod 601 is fixedly mounted in the extrusion tube 603, a piston pressure plate 604 is fixedly mounted on the output end of the reciprocating push rod 601, a shielding piece 602 is fixedly mounted on the upper end of the piston pressure plate 604, a filter screen 607 is provided on the piston pressure plate 604, a positioning bracket 606 is provided on the reciprocating push rod 601, the reciprocating push rod 601 is fixed to the extrusion tube 603 through the positioning bracket 606, an installation notch is opened on the piston pressure plate 604, and the filter screen 607 is installed on the piston pressure plate 604 through the installation notch.

[0023] Specifically, the reciprocating push rod 601 can drive the piston pressure plate 604 to move forward. After the piston pressure plate 604 moves forward, it will squeeze the material, so that the moisture in the material is discharged through the filter 607, thereby reducing the moisture content of the material and ensuring stable operation of the equipment. The shielding piece 602 will follow the piston pressure plate 604 to move back and forth, thereby blocking the feed pipe 605 and preventing the material from entering the extrusion tube 603 at will.

[0024] like Figure 2 and Figure 4 As shown, the sealing mechanism 7 includes a positioning sleeve 701 fixedly mounted on the end of the extrusion tube 603, a return spring 702 is provided in the positioning sleeve 701, an electromagnet 707 is fixedly mounted in the positioning sleeve 701, a telescopic rod 704 is movably mounted in the positioning sleeve 701, a sealing plug 705 is fixedly mounted on one end of the telescopic rod 704, an armature slider 703 is fixedly mounted on the other end of the telescopic rod 704, a connecting leg 706 is provided on the sealing plug 705, the sealing plug 705 is connected to the telescopic rod 704 through the connecting leg 706, a movable hole is opened at the front end of the positioning sleeve 701, and the telescopic rod 704 extends out of the positioning sleeve 701 through the movable hole.

[0025] Specifically, after the electromagnet 707 is turned off, it will release the armature slider 703. At this time, the return spring 702 will push the armature slider 703 to move forward. After the armature slider 703 moves forward, it will drive the telescopic rod 704 to move forward. After the telescopic rod 704 moves forward, it will drive the sealing cover 705 to move forward, so that the sealing cover 705 leaves the extrusion tube 603, which is convenient for unloading. After starting the electromagnet 707, it will adsorb the armature slider 703, so that the sealing cover 705 is blocked at the front end of the extrusion tube 603, which is convenient for extruding materials.

[0026] Working principle: the material screened out by the wet magnetic separator will be collected by the collecting funnel 5, and the material collected by the collecting funnel 5 will fall into the squeezing tube 603. After the material falls into the squeezing tube 603, the reciprocating push rod 601 can be started. After starting the reciprocating push rod 601, it will drive the piston pressure plate 604 to move forward. After the piston pressure plate 604 moves forward, it will squeeze the material, so that the moisture in the material is discharged through the filter screen 607, thereby reducing the moisture content of the material and ensuring stable operation of the equipment. After the moisture in the material is squeezed out, the electromagnet 707 can be turned off. After turning off the electromagnet 707, it will release the armature slider 703. Since one end of the return spring 702 is connected to the armature On the iron slider 703, the other end of the return spring 702 is connected to the bottom of the positioning sleeve 701, one end of the telescopic rod 704 is fixed on the armature slider 703, and the other end of the telescopic rod 704 is fixed on the connecting leg 706, so the return spring 702 will push the armature slider 703 to move forward. After the armature slider 703 moves forward, it will drive the telescopic rod 704 to move forward. After the telescopic rod 704 moves forward, it will drive the sealing plug cover 705 to move forward, so that the sealing plug cover 705 leaves the extrusion tube 603. After the sealing plug cover 705 leaves the extrusion tube 603, the reciprocating push rod 601 can be controlled to continue moving forward, thereby discharging the material with a lower water content.

[0027] 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 present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
