Abstract
Description
Technical Field
[0001] This utility model relates to the field of mineral sorting technology, and in particular to a feed trough for an electrostatic separator with a guide plate. Background Technology
[0002] An electrostatic separator is a device that uses an electric field to separate materials. It is widely used in industries such as mining, metallurgy, chemical, and food. The working principle of an electrostatic separator is based on the difference in conductivity and dielectric constant of different materials. Under the action of an electric field, materials with good conductivity are attracted to the anode, while materials with poor conductivity are attracted to the cathode, thereby achieving the separation of materials.
[0003] Existing feeding methods mostly involve centralized feeding of materials to the electric separator through a feed chute equipped with a guide plate. This presents the following problems in actual operation:
[0004] 1) In order to facilitate the guidance of minerals into the electrostatic separator, inclined guide plates are usually installed on the outside of the discharge port of the feed trough and the feed port of the electrostatic separator. However, since the size of the discharge port of the feed trough is fixed, when a large amount of minerals are fed in at one time, it is easy to cause blockage in the feed trough.
[0005] 2) When minerals are put into the feed trough, the minerals are in direct contact with the feed trough. The long-term impact of the minerals on the feed trough can easily cause deformation of the feed trough outlet, affecting the normal use of the equipment. Utility Model Content
[0006] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.
[0007] Specifically, the technical problem to be solved by this utility model is to provide an electric separator feed trough with a guide plate, so as to solve the technical problem that the current feed trough usually has an inclined guide plate on the outside of the feed trough and the feed inlet of the electric separator. However, since the size of the feed trough's outlet is fixed, when a large amount of minerals are fed in at one time, it is easy to cause blockage in the feed trough.
[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution:
[0009] An electric separator feed trough with a guide plate includes a trough body, a collection hopper is fixedly installed on the top of the trough body, a reinforcing plate is fixedly installed in the trough body and below the collection hopper, and a discharge port is opened on the inner side of the reinforcing plate.
[0010] The trough body contains symmetrically distributed guide plates below the collection hopper. A slider is provided between the guide plate and the reinforcing plate. A dual-axis motor is fixedly installed on one side of the reinforcing plate, and the output shaft of the dual-axis motor is connected to a bidirectional lead screw. The sliders are symmetrically distributed at both ends of the bidirectional lead screw. A guide groove is provided on the side of the reinforcing plate near the bidirectional lead screw to achieve limited sliding of the slider. One end of the slider extends out of the reinforcing plate through the guide groove and is hinged to the guide plate. The other end of the slider extends into the reinforcing plate through the guide groove and is threadedly connected to the bidirectional lead screw.
[0011] As an improved technical solution, the sliders are symmetrically distributed on both sides of the guide plate, and the end of the slider away from the slider is inclined upward. A slide rod parallel to the bidirectional lead screw is also fixedly installed in the guide groove on the side of the reinforcing plate away from the bidirectional lead screw, and both ends of the slide rod extend into the reinforcing plate.
[0012] As an improved technical solution, an auxiliary arm is provided between the guide plate and the reinforcing plate. A connecting shaft is fixedly installed on both sides of the guide plate. One end of the auxiliary arm is hinged to the reinforcing plate, and the other end of the auxiliary arm is hinged to the guide plate through the connecting shaft.
[0013] As an improved technical solution, the bottom of the hopper is provided with an opening that communicates with the trough body. On both sides of the hopper opening and above the reinforcing plate, there are baffle seats distributed in parallel. A first push rod is fixedly installed on one side of the baffle seat. The piston shaft of the first push rod is connected to a first baffle. One end of the first baffle extends into the baffle seat, and the other end of the first baffle is located above the guide plate.
[0014] As an improved technical solution, a second push rod is fixedly installed on the inner side of the baffle seat, and the second push rod is located below the hopper. The piston shaft of the second push rod passes through one end of the baffle seat and is connected to a second baffle. One end of the second baffle is hinged to the end of the baffle seat away from the first baffle. The end of the second baffle near the baffle seat is inclined upward.
[0015] As an improved technical solution, the first baffle is movably connected to both sides of the opening in the hopper via a baffle seat, and the inner side of the first baffle is provided with a sliding groove that is compatible with the second push rod.
[0016] As an improved technical solution, the bottom of the tank body is fixedly installed with fittings, which are symmetrically distributed around the tank body.
[0017] After adopting the above technical solution, the beneficial effects of this utility model are:
[0018] 1. This utility model uses the output shaft of a dual-axis motor to drive a bidirectional lead screw to rotate, causing the slider to move along the axial direction of the slide bar. This increases the distance between the guide plates connected to the slider and the path connecting to the feed inlet of the electrostatic separator, thereby preventing excessive material in the tank body from causing blockage.
[0019] 2. In this utility model, the first baffle connected to the piston shaft of the first push rod descends under the restriction of the baffle seat and moves to the top of the guide plate, thereby facilitating the mineral to be guided into the feed port of the electrostatic separator through the inclined guide plate.
[0020] 3. In this utility model, the second baffle blocks the input minerals, and after being guided by the guide plate, the minerals enter the feed port of the electrostatic separator through the discharge port. This avoids long-term impact on the tank body during the mineral addition process, thereby reducing the probability of damage and deformation to the tank body. Attached Figure Description

[0033] like Figures 1 to 5As shown in the figure, this embodiment provides a feed trough for an electrostatic separator with a guide plate. This feed trough includes a main body 1, a hopper 2 fixedly mounted on the top of the main body 1, a reinforcing plate 3 fixedly mounted in the main body 1 below the hopper 2, a discharge port 4 on the inner side of the reinforcing plate 3, a guide platform 6 symmetrically distributed in the main body 1 below the hopper 2, a slider 5 between the guide platform 6 and the reinforcing plate 3, a dual-axis motor 7 fixedly mounted on one side of the reinforcing plate 3, and a bidirectional lead screw 8 connected to the output shaft of the dual-axis motor 7, with sliders 5 symmetrically distributed at both ends of the bidirectional lead screw 8. A guide groove for limiting the sliding movement of sliders 5 is provided on the side of the reinforcing plate 3 near the bidirectional lead screw 8. One end of slider 5 extends out of the reinforcing plate 3 through the guide groove and is hinged to the guide platform 6; the other end of slider 5 extends into the reinforcing plate 3 through the guide groove and is threadedly connected to the bidirectional lead screw 8. The main body 1 can be installed at the feed inlet of the electrostatic separator through the bottom slot, and the material to be processed is added to the main body 1 through the collection hopper 2. The reinforcing plate 3 is located above the discharge port 4 and fixed in the main body 1, which improves the overall structural strength of the main body 1, so that the main body 1 is not easily damaged or deformed when the material is impacted. The size of the discharge port 4 is fixed, but the size of the path connecting it to the feed inlet of the electrostatic separator depends on the distance between the sliders 5. The inner side of each slider 5 is provided with a thread that is compatible with the bidirectional lead screw 8, and the threads in the symmetrically distributed sliders 5 are opposite in direction. The dual-shaft motor 7 can drive the bidirectional lead screw 8 to rotate in the reinforcing plate 3, which drives the sliders 5 to move linearly in the guide groove in the reinforcing plate 3, and drives the guide plate 6 to move synchronously. When the distance between the sliders 5 is larger, the path connecting the discharge port 4 and the feed inlet of the electrostatic separator is larger, thereby avoiding blockage inside the feed trough when too much mineral is added.
[0034] The sliders 5 are symmetrically distributed on both sides of the guide plate 6, and the end of the slider 5 away from the slider 5 is inclined upward. The guide groove on the side of the reinforcing plate 3 away from the bidirectional lead screw 8 is also fixedly installed with a slide rod 9 arranged parallel to the bidirectional lead screw 8, and both ends of the slide rod 9 extend into the reinforcing plate 3. When the dual-axis motor 7 drives the bidirectional lead screw 8 to rotate, the slider 5 moves in a straight line along the axis of the slide rod 9 in a direction parallel to the bidirectional lead screw 8, and keeps both sides of the guide plate 6 horizontal.
[0035] An auxiliary arm 10 is provided between the guide plate 6 and the reinforcing plate 3. A connecting shaft 11 is fixedly installed on both sides of the guide plate 6. One end of the auxiliary arm 10 is hinged to the reinforcing plate 3, and the other end of the auxiliary arm 10 is hinged to the guide plate 6 through the connecting shaft 11. The auxiliary arm 10 is L-shaped, and there are four auxiliary arms 10, which are symmetrically distributed on both sides of the corresponding guide plate 6. When the guide plate 6 moves with the slider 5, the auxiliary arm 10 provides support for the inclined guide plate 6. As the distance between the sliders 5 increases, the inclination angle of the guide plate 6 with the slider 5 as the center increases, which facilitates the mineral to be guided into the feed port of the electrostatic separator through the inclined guide plate 6.
[0036] The bottom of the hopper 2 is provided with an opening that communicates with the main body 1 of the tank. On both sides of the opening of the hopper 2 and above the reinforcing plate 3, there are baffle seats 12 arranged in parallel. A first push rod 13 is fixedly installed on one side of the baffle seat 12. The piston shaft of the first push rod 13 is connected to a first baffle 14. One end of the first baffle 14 extends into the baffle seat 12, and the other end of the first baffle 14 is located above the guide plate 6. The angle between the baffle seat 12 and the reinforcing plate 3 is ninety degrees. The drive of the output shaft in the first push rod 13 can control the first baffle 14 to move above the guide plate 6 under the restriction of the baffle seat 12, thereby cooperating with the inclined guide plate 6 to guide the minerals entering the main body 1 of the tank.
[0037] A second push rod 15 is fixedly installed on the inner side of the baffle seat 12, and the second push rod 15 is located below the collection hopper 2. The piston shaft of the second push rod 15 passes through one end of the baffle seat 12 and is connected to a second baffle 16. One end of the second baffle 16 is hinged to the end of the baffle seat 12 away from the first baffle 14. The end of the second baffle 16 near the baffle seat 12 is inclined upward. The second push rod 15 can control the extension of the piston shaft to make the second baffle 16 deflect and tilt under the restriction of the baffle seat 12, thereby blocking the minerals entering the tank body 1 through the opening in the collection hopper 2, and preventing the minerals from directly hitting the tank body 1 and causing deformation and damage to the tank body 1.
[0038] The first baffle 14 is movably connected to both sides of the opening in the hopper 2 via the baffle seat 12. The inner side of the first baffle 14 is provided with a sliding groove 17 that is compatible with the second push rod 15. The sliding groove 17 allows the first baffle 14 to move in the baffle seat 12 without affecting the operation of the second push rod 15 which is fixedly installed on the baffle seat 12.
[0039] The bottom of the tank body 1 is fixedly equipped with a fitting 18. The fittings 18 are symmetrically distributed around the tank body 1, and the inner side of each fitting 18 has bolt holes for connecting with the electrostatic separator. There are four fittings 18. The discharge port 4 in the tank body 1 can be connected with the inlet of the electrostatic separator by installing bolts in the fittings 18 and engaging with the slots at the bottom of the tank body 1, thus ensuring the stability of the electrostatic separator's feeding operation.
[0040] In use, the discharge port 4 of the tank body 1 is connected to the inlet of the electrostatic separator by installing bolts in the mounting part 18 to fit the bottom slot of the tank body 1. Minerals are added to the tank body 1 through the collecting hopper 2. After the minerals pass through the opening connecting the collecting hopper 2 and the tank body 1, they fall onto the guide plates 6 on both sides of the reinforcing plate 3. Guided by the inclined guide plates 6, the minerals are fed into the inlet of the electrostatic separator through the discharge port 4. When there are many minerals in the tank body 1, the output shaft of the dual-shaft motor 7 drives the bidirectional lead screw 8 to rotate, so that the threaded slider 5 moves in a straight line along the axis of the slide rod 9, keeping it parallel to the bidirectional lead screw 8. This increases the distance between the guide plates 6 and the path connecting to the inlet of the electrostatic separator, thereby preventing blockage caused by excessive material in the tank body 1. During this process, as... The increased spacing between sliders 5 causes the guide plate 6 above the reinforcing plate 3 to tilt at an angle centered on slider 5 under the support of the auxiliary arm 10. This, combined with the first baffle 14 connected to the piston shaft of the first push rod 13, moves downwards under the constraint of the baffle seat 12, moving above the guide plate 6. This facilitates the minerals being guided into the feed inlet of the electrostatic separator via the tilted guide plate 6. Simultaneously, the extension of the piston shaft of the second push rod 15 pushes the second baffle 16 to deflect and tilt under the constraint of the baffle seat 12. This causes the minerals falling into the hopper 2 to pass through the second baffle 16 before falling onto the guide plate 6. Finally, guided by the guide plate 6, the minerals enter the feed inlet of the electrostatic separator through the discharge port 4. This avoids long-term impact on the tank body 1 during mineral addition, thus reducing the probability of damage and deformation to the tank body 1.
[0041] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
