Description

Technical Field

[0001] The utility model belongs to the technical field of magnetic separators, and in particular relates to a lifting bracket for a magnetic separator. Background Art

[0002] Drum magnetic separators are widely used in the fields of magnetic ore beneficiation, heavy medium recovery in coal preparation plants, and magnetic seed recovery in purified water. According to the direction of rotation of the drum and the internal structure of the tank, they are usually divided into downstream magnetic separators, countercurrent magnetic separators, and semi-countercurrent magnetic separators. This type of equipment has large processing capacity per unit, simple structure, simple operation, stable operation, and few operating parameters that affect the production process. Drum magnetic separators are mainly composed of magnetic separation drums, separation tanks, frames, driving components, and feed tanks. The magnetic separation drum is fixed to the upper part of the frame through bearing seats installed on both sides of the main shaft of the drum. There is no connection or interference between the separation tank and the drum.

[0003] When delivering materials, some magnetic separators in the prior art usually use a lifting mechanism to deliver the materials to be screened into the magnetic separator for magnetic separation. At present, when the lifting mechanism on one side is delivering materials, the materials often stick to the lifting mechanism, resulting in that the materials cannot all fall into the magnetic separator during transportation. Some of the materials fall to the ground during the lifting process, and some of them remain stuck to the lifting mechanism, resulting in reduced efficiency in material transportation. Utility Model Content

[0004] The utility model aims to provide a lifting bracket for a magnetic separator, so as to solve the problem in the prior art that materials to be magnetically separated adhere to the lifting device and cannot be removed.

[0005] The technical solution of the utility model is as follows:

[0006] A lifting bracket for a magnetic separator includes: a lifting device, the lifting device includes a conveyor belt arranged obliquely upward, the conveyor belt is provided with a plurality of baffle plates, a receiving plate is rotatably provided on the lifting device, the receiving plate contacts the downward side of the conveyor belt, and the other end extends into the magnetic separator, an elastic member is installed between the lifting device and the receiving plate on the receiving plate, a comb plate is provided above the receiving plate and can slide back and forth along the length direction of the receiving plate, and a gap exists between the bottom of the comb plate and the top surface of the receiving plate to ensure the passage of materials.

[0007] The beneficial effects are: the material to be transported by the lifting device can be effectively removed, avoiding the material adhering to the conveyor belt or falling on the ground, affecting the transmission efficiency of the conveyor belt; the material on the receiving plate can be flattened and evenly lifted into the magnetic separator, improving the effect of magnetic separation of the material.

[0008] In order to enable the utility model to support the material baffle plate and the conveyor belt, the lifting device further includes a support frame, the material baffle plate is rotatably arranged on the support frame, and the elastic member is installed between the material baffle plate and the support frame.

[0009] In order to enable the utility model to avoid interference between the material receiving plate and the material blocking plate, further, the elastic member is a torsion spring, one end of the torsion spring is connected to the material receiving plate, and the other end is connected to the support frame. When the material blocking plate contacts the material receiving plate, it pushes the material receiving plate to rotate, and the torsion spring is twisted.

[0010] In order to enable the utility model to drive the comb plate to move back and forth in a straight line, further, a reciprocating motion mechanism for driving its reciprocating motion is installed on the comb plate, the reciprocating motion mechanism is a screw mechanism, the comb plate is installed on the screw nut of the screw mechanism, and the support frame is also equipped with a guide assembly for making the screw nut run along a straight line, the guide assembly includes a mounting plate installed on the support frame, a guide groove is opened in the mounting plate, a slider is slidably arranged in the guide groove, and the slider is fixedly connected to the screw nut.

[0011] In order to enable the utility model to drive the reciprocating motion mechanism to operate, further, a driving mechanism is installed on the reciprocating motion mechanism, and the driving mechanism includes a driving wheel, a driven wheel and a belt. The driving wheel is installed on the rotating shaft of the conveyor belt, the driven wheel is connected to the screw of the screw mechanism, and the belt transmission is connected between the driving wheel and the driven wheel.

[0012] In order to enable the utility model to reduce the friction between the material receiving plate and the conveyor belt, further, the end of the material receiving plate in contact with the conveyor belt is provided with a scraper portion, and the scraper portion is in contact with the conveyor belt.

[0013] In order to make the scraper plate of the utility model wear-resistant, further, the scraper part is made of hard wear-resistant material.

[0014] In order to prevent the objects to be screened from adhering to the comb plate, the bottom of the comb plate is made of a soft brush.

[0015] The beneficial effects of the utility model are:

[0016] 1. Place the material to be magnetically separated on the conveyor belt, and transport it to the magnetic separator through the conveyor belt. The material to be magnetically separated on the conveyor belt falls on the receiving plate. When the conveyor belt is running, the driving mechanism and the reciprocating motion mechanism drive the comb plate to reciprocate in a straight line. When the material falling on the receiving plate has uneven thickness, the comb plate will contact with the material and flatten it during the reciprocating motion. When the material with uniform thickness falls into the magnetic separator, the magnetic separation effect is better.

[0017] 2. When there is material adhering to the conveyor belt, since one end of the receiving plate contacts the downward side of the conveyor belt, the material adhering to the conveyor belt is scraped off by the scraping part of the receiving plate and falls onto the receiving plate, thereby keeping the conveyor belt clean and preventing the material on the conveyor belt from falling off and contaminating the ground, or from adhering to the conveyor belt all the time and affecting the conveying efficiency of the conveyor belt.

[0018] 3. When the receiving plate receives materials for a long time, there may be a situation where the material adheres to the receiving plate. When the baffle plate contacts the scraper part, the receiving plate deflects. When the receiving plate is reset under the action of the torsion spring, it will collide with the conveyor belt. The vibration generated by the collision causes the material on the receiving plate to fall off, thus avoiding the accumulation of materials on the receiving plate.

[0019] 4. When the comb plate is in contact with the material, the material may stick to it. When the comb plate rotates to the maximum angle, since the comb plate is a soft brush, it bends when it contacts the receiving plate, causing the material stuck on the comb plate to fall off.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] like Figure 1-3As shown, the lifting bracket for magnetic separator includes a lifting device 1, the lifting device 1 includes a conveyor belt 11 arranged obliquely upward, and a plurality of baffle plates 12 are arranged on the conveyor belt 11, a receiving plate 2 is rotatably arranged on the lifting device 1, the receiving plate 2 contacts the downward side of the conveyor belt 11, and the other end extends into the magnetic separator, an elastic member 3 is installed between the lifting device 1 and the receiving plate 2, and a comb plate 4 is provided above the receiving plate 2 that can slide back and forth along the length direction of the receiving plate 2, and there is a gap between the bottom of the comb plate 4 and the top surface of the receiving plate 2 to ensure the passage of materials. The lifting device 1 also includes a support frame 13, the baffle plate 12 is rotatably arranged on the support frame 13, and the elastic member 3 is installed between the baffle plate 12 and the support frame 13; the conveyor belt 11 and the receiving plate 2 are supported by the support frame 13.

[0028] The elastic member 3 is a torsion spring, one end of which is connected to the material receiving plate 2, and the other end is connected to the support frame 13. When the material baffle plate 12 contacts the material receiving plate 2, it pushes the material receiving plate 2 to rotate, and the torsion spring twists; when the material receiving plate 2 contacts the material baffle plate 12, the material baffle plate 12 will push the material receiving plate 2 to deflect the moving angle so that the material receiving plate 2 can move with the conveyor belt 11, thereby avoiding interference between the material baffle plate 12 and the material receiving plate 2.

[0029] A reciprocating mechanism 6 for driving the reciprocating motion of the comb plate 4 is installed on the comb plate 4, and the reciprocating mechanism 6 is a screw mechanism. The comb plate 4 is installed on the screw nut of the screw mechanism. A guide assembly 8 for making the screw nut run along a straight line is also installed on the support frame 13. The guide assembly 8 includes a mounting plate installed on the support frame 13, and a guide groove 81 is opened in the mounting plate. A slider 82 is slidably arranged in the guide groove 81, and the slider 82 is fixedly connected to the screw nut; the screw rotates to make the screw nut slide along the screw and under the action of the guide assembly 8, the screw nut drives the comb plate 4 to reciprocate. When material falls on the receiving plate 2, the reciprocating motion of the comb plate 4 flattens the material.

[0030] In other embodiments, the comb plate 4 may be driven to perform reciprocating linear motion by a driving member such as an electric telescopic rod or an electric hydraulic rod.

[0031] A driving mechanism 7 is installed on the reciprocating motion mechanism 6, and the driving mechanism 7 includes a driving wheel 71, a driven wheel 72 and a belt 73. The driving wheel 71 is installed on the rotating shaft of the conveyor belt 11, the driven wheel 72 is connected to the screw of the screw mechanism, and the belt 73 is transmission-connected between the driving wheel 71 and the driven wheel 72; when the conveyor belt 11 moves, the driving wheel 71 rotates, and then drives the driven wheel 72 to rotate through the belt 73, and the rotation of the driven wheel 72 drives the screw mechanism to operate, thereby driving the comb plate 4 to reciprocate linearly.

[0032] The end of the receiving plate 2 in contact with the conveyor belt 11 is provided with a scraper portion 5, and the scraper portion 5 is in contact with the conveyor belt 11; the scraper portion 5 is in contact with the conveyor belt 11 to reduce the friction between the receiving plate 2 and the conveyor belt 11, so as to reduce the power consumption of the lifting device 1.

[0033] The scraper part 5 is made of a hard and wear-resistant material. Since the scraper part 5 is in contact with the conveyor belt 11 all the time, the scraper part 5 is prevented from wearing out quickly. At the same time, when the receiving plate 2 passes over the baffle plate 12, the scraper part 5 is made of a hard and wear-resistant material and can hit the conveyor belt 11. If the material on the receiving plate 2 is adhered, the vibration generated by the impact will cause the material on the receiving plate 2 to fall off.

[0034] The bottom material of the comb plate 4 is a soft brush. When the receiving plate 2 is deflected to the maximum angle, the receiving plate 2 contacts the soft brush and can bend the soft brush. By setting the soft brush, when the receiving plate 2 is deflected and the soft brush is bent, the material in the brush will fall off. If only the comb plate 4 is set, the side of the comb plate 4 that contacts the material will also be stuck with the material.

[0035] The working principle of this utility model:

[0036] The material to be magnetically separated is placed on the conveyor belt 1, and the material to be magnetically separated is transported to the magnetic separator through the conveyor belt 1. The material to be magnetically separated on the conveyor belt 11 falls on the receiving plate 2. When the conveyor belt 11 is running, the driving mechanism 7 and the reciprocating mechanism 6 drive the comb plate 4 to reciprocate in a straight line. When the material falling on the receiving plate 2 has uneven thickness, the comb plate 4 will contact with the material and flatten the material during the reciprocating motion. When the material with uniform thickness falls into the magnetic separator, the magnetic separation effect is better; when there is material adhering to the conveyor belt 11, since one end of the receiving plate 2 contacts the downward side of the conveyor belt 11, the material adhering to the conveyor belt 11 is scraped by the scraper part 5 on the receiving plate 2 and falls onto the receiving plate 2, thereby keeping the conveyor belt 11 clean. The material on the conveyor belt 11 is prevented from falling off and polluting the ground, or from being stuck on the conveyor belt 11 all the time, thus affecting the conveying efficiency of the conveyor belt 11; when the receiving plate 12 receives material for a long time, there may be a situation where material sticks to the receiving plate 5. When the baffle plate 12 contacts the scraper portion 5, the receiving plate 2 is deflected. When the receiving plate 2 is reset under the action of the torsion spring, it will collide with the conveyor belt 11. The vibration generated by the collision causes the material on the receiving plate 2 to fall off, thus avoiding the accumulation of material on the receiving plate 2; the comb tooth plate 4 may also adhere to the material during the process of contacting with the material. When the comb tooth plate 4 rotates to the maximum angle, since the comb tooth plate 4 is a soft brush, the comb tooth plate 4 bends when it abuts against the receiving plate 2, causing the material stuck on the comb tooth plate 4 to fall off.

[0037] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0038] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
