Description

Technical Field

[0001] The utility model relates to a screening device, and more specifically, to an ore waste screening device. Background Technique

[0002] One of the recovery operations of ore waste is to crush the ore waste and then add water to form a pulp. While flowing out, a magnetic screening operation is carried out on the pulp, so that the ore and magnetic substances can be well separated.

[0003] The existing operation method is as follows: using the magnetic field system of the magnetic separation mechanism, which uses the magnetic field to generate attraction or repulsion on the magnetic components in the material, so as to realize the separation of the material. When the material passes through the magnetic field area, the magnetic components will be attracted or repelled by the magnetic force and thus separated. The non-magnetic material will continue to move along the flow direction and be excluded.

[0004] The existing devices are divided into: a magnetic field system, a feeding device, a sorting area, and a collecting device. Among them, the magnetic field system is usually composed of a permanent magnet or an electromagnet. The permanent magnet magnetic separator uses magnetic poles made of permanent magnetic materials (such as neodymium iron boron, ferrite, etc.) to generate a constant magnetic field, while the electromagnet magnetic separator generates an adjustable magnetic field by passing an electric current through a coil.

[0005] However, the existing products have the following problems: 1. When the pulp flow rate is too large, if the distance between the magnetic separation mechanism and the bottom of the cavity is too small, the magnetic separation efficiency will be too low; 2. When the pulp flow rate is too small, if the magnetic separation mechanism is too far from the bottom of the cavity, the magnetic separation effect on the ore at the bottom will be poor, affecting the screening effect. Content of the Utility Model

[0006] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide an ore waste screening device, which can adjust the pulp flow rate and at the same time adjust the distance between the magnetic separation mechanism and the pulp, so as to ensure both the magnetic separation efficiency and the magnetic separation effect.

[0007] To achieve the above purpose, the utility model provides the following technical solution: an ore waste screening device, including a box body, a magnetic separation mechanism and a feeding box. The feeding box is installed on one side of the box body. An inlet is opened between the box body and the feeding box. An adjusting seat is arranged in the box body. Both ends of the adjusting seat are provided with sliding grooves extending upwards. The magnetic separation mechanism is slidably connected in the sliding grooves and forms a flowing space for the pulp to flow through with the bottom of the box body;

[0008] Both ends of the adjusting seat are provided with adjusting mechanisms for driving the magnetic separation mechanism to move up and down. At least two groups of limiting components are arranged in the sliding grooves.

[0009] The present utility model is further configured as follows: The adjusting mechanism includes an adjusting motor, a lead screw, and a guide rod. The adjusting motor is connected to the lead screw and is used to drive the lead screw to rotate;

[0010] The magnetic separation mechanism includes a moving seat. Threaded holes screwed with the lead screw and guide holes cooperating with the guide rod are provided at both ends of the moving seat.

[0011] The present utility model is further configured as follows: The two limiting components are respectively an upper limiting ring and a lower limiting ring, and the upper limiting ring and the lower limiting ring are respectively fixedly installed on the guide rod.

[0012] The present utility model is further configured as follows: The guide rod includes a middle rod portion and end rod portions.

[0013] The present utility model is further configured as follows: A sealing mechanism is provided at the feed inlet, and the sealing mechanism is used to adjust the opening size of the feed inlet.

[0014] The present utility model is further configured as follows: The sealing mechanism includes a sealing plate, a sealing motor, a lifting rod, a ball nut, and a rotating rod. The sealing motor is connected to the rotating rod. A stroke groove is provided at one end of the lifting rod. The lifting rod is arranged in cooperation with the rotating rod through the ball nut. The sealing plate is arranged at the end of the lifting rod facing away from the rotating rod.

[0015] The present utility model is further configured as follows: It further includes a controller, and the controller is electrically connected to the sealing mechanism and the adjusting mechanism respectively.

[0016] To sum up, the present utility model has the following beneficial effects: When the magnetic force of the magnetic separation mechanism is constant, the height position of the magnetic separation mechanism can be adjusted, so that the height position between the magnetic separation mechanism and the bottom of the box body changes, and the height of the flow space and the penetrable space can be controlled.

Specific embodiments

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the accompanying drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" refer to the directions towards or away from the geometric center of a specific component, respectively.

[0023] Refer to Figures 1 to 4 As shown, to achieve the above object, the present invention provides the following technical solution: An ore waste screening device includes a box body 1, a magnetic separation mechanism 2 and a feed box 3. The feed box 3 is installed on one side of the box body 1. A feed inlet 11 is provided between the box body 1 and the feed box 3. An adjusting seat 4 is arranged inside the box body 1. Sliding grooves 41 extending upward are arranged at both ends of the adjusting seat 4. The magnetic separation mechanism 2 is slidably connected in the sliding grooves 41 and forms a flowing space for the ore pulp to flow through with the bottom of the box body 1.

[0024] Adjusting mechanisms 5 are arranged at both ends of the adjusting seat 4. The adjusting mechanisms 5 are used to drive the magnetic separation mechanism 2 to move up and down. At least two groups of limiting components 6 are arranged in the sliding grooves 41.

[0025] With the design of the present invention, when the magnetic force of the magnetic separation mechanism 2 is constant, the height position of the magnetic separation mechanism 2 can be adjusted, so that the height position between the magnetic separation mechanism 2 and the bottom of the box body 1 changes, and the height of the flowing space and the passing space can be controlled, so that the magnetic separation mechanism 2 can fully provide magnetic force to the ore pulp during rotation, ensuring the ore pulp flow rate while ensuring the magnetic separation effect.

[0026] The design of the two groups of limiting components 6 can limit the upward and downward strokes of the magnetic separation mechanism 2, avoiding poor magnetic separation effect caused by excessive strokes.

[0027] The core of the magnetic separation mechanism 2 is an internal electromagnet and an externally rotating cylinder. The magnetic attraction range of the electromagnet can be designed to be 120° according to the positions of the feed inlet 11 and the discharge outlet. When exceeding the position, the magnetic force disappears, and the magnetic substances on the cylinder fall out from the discharge outlet to complete the screening operation.

[0028] The adjusting mechanism 5 includes an adjusting motor 51, a screw rod 52 and a guide rod 53. The adjusting motor 51 is connected to the screw rod 52 to drive the screw rod 52 to rotate.

[0029] The magnetic separation mechanism 2 includes a movable seat 21 , and both ends of the movable seat 21 are provided with threaded holes threadedly connected to the screw rod 52 and guide holes matched with the guide rod 53 .

[0030] With this structural design, when the adjusting motor 51 drives the screw rod 52 to rotate, the movable seat 21 moves up and down along the axial direction of the guide rod 53 through the threaded hole that cooperates with the screw rod 52, thereby achieving a stable lifting and lowering effect.

[0031] The two sets of limiting components 6 are respectively an upper limiting ring 61 and a lower limiting ring 62, and the upper limiting ring 61 and the lower limiting ring 62 are respectively fixedly mounted on the guide rod 53. The upper limiting ring 61 and the lower limiting ring 62 can limit the moving distance of the moving seat 21 on the guide rod 53.

[0032] like Figure 2 As shown, the movable seat 21 is only a part, and the complete movable seat 21 includes a connecting portion located in the middle, which is in a "冂" shape, and sliding portions located on both sides of the connecting portion. The design of this structure can ensure the installation of the magnetic separation mechanism 2.

[0033] The guide rod 53 includes a middle rod portion 531 and an end rod portion 532. The end rod portion 532 is provided with two groups and is respectively arranged at the two ends of the middle rod portion 531. The diameter length of the middle rod portion 531 is larger than the diameter length of the end rod portion 532. The upper limit ring 61 and the lower limit ring 62 are respectively installed at the connection between the middle rod portion 531 and the end rod portion 532.

[0034] A sealing mechanism 7 is provided at the feed inlet 11 , and the sealing mechanism 7 is used to adjust the opening size of the feed inlet 11 .

[0035] The sealing mechanism 7 includes a sealing plate 71, a sealing motor 72, a lifting rod 73, a ball nut and a rotating rod 74. The sealing motor 72 is connected to the rotating rod 74. A travel groove is provided at one end of the lifting rod 73. The lifting rod 73 is matched with the rotating rod 74 through a ball nut. The sealing plate 71 is arranged at one end of the lifting rod 73 facing away from the rotating rod 74.

[0036] With this structural design, when the sealing motor 72 is started, the rotating rod 74 is driven to rotate, and under the action of the ball nut, the lifting rod 73 performs linear motion.

[0037] A controller is also included, which is electrically connected to the sealing mechanism 7 and the adjusting mechanism 5. The design of the controller can synchronously control the opening size of the feed port 11 and the height of the magnetic separation mechanism 2.

[0038] The above are only the preferred embodiments of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. Any technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as within the protection scope of the present utility model.
