Description

Technical Field

[0001] The utility model relates to the technical field of magnetic separation feeding, in particular to a magnetic separation feeding tool for processing high-purity quartz sand. Background Art

[0002] The magnetic separator uses magnetic equipment to separate magnetic materials from other materials based on the magnetic characteristics of the materials. Quartz sand is quartz particles made by crushing quartz stone. It is a non-metallic mineral and belongs to silicate minerals. The size of quartz sand particles will vary. When the quartz sand particles are larger, the force exerted by the quartz sand particles on the magnetic separator is relatively large. Long-term collision will affect the magnetic separator. Therefore, the magnetic separation feed tooling needs to be screened and crushed before the quartz sand enters the magnetic separator.

[0003] For example, an anti-clogging feed device for a magnetic separator, disclosed in publication number CN113058323A, comprises a screening assembly comprising a first screening element disposed within a first feed channel. The first screening element comprises a fixed frame disposed horizontally within the first feed channel, wherein a plurality of parallel connecting rods are rotatably connected within the fixed frame, with adjacent connecting rods spaced uniformly apart. A flipping assembly comprises a rotating rod disposed horizontally on the centerline of an opening, wherein the axis of the rotating rod coincides with the plane of the opening, and the ends of the rotating rod are rotatably connected to the inner sidewall of the feed bin. The adjacent sides of the fixed frame of the first screening element and the fixed frame of the second screening element are simultaneously fixed to the rotating rod.

[0004] The above-mentioned magnetic separation feeding tooling is used to block the larger quartz sand on the rotating rod. The blocked quartz sand is then dropped onto the crusher through the flipping assembly. The crushed quartz sand then enters the magnetic separator. Since the position of the rotating rod changes during the rotation, quartz sand cannot be continuously added to the feeding position during the flipping process. The feeding position must be flipped after all the quartz sand has fallen. When quartz sand accumulates on the rotating rod, it blocks the gap between adjacent rotating rods. Quartz sand that continues to be added from above will all be blocked above and cannot be screened. Therefore, the amount added each time needs to be controlled. Utility Model Content

[0005] The purpose of the utility model is to provide a magnetic separation feeding tool for high-purity quartz sand processing, so as to solve the problem raised in the above background technology that the magnetic separation feeding tool on the current market can only be turned over after all the quartz sand has fallen off. When the quartz sand accumulates on the rotating rod, it blocks the gap between adjacent rotating rods. The quartz sand that continues to be input from above will be blocked on the top and cannot be screened, so the amount input each time needs to be controlled.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a magnetic separation feeding tool for high-purity quartz sand processing, comprising a feeding tool body and a feeding port, the feeding port being arranged on the feeding tool body, and an adjusting mechanism being installed inside the feeding tool body, by which the quartz sand is limited and quartz sand of different volumes can be separated.

[0007] Preferably, a crushing roller is provided at the bottom of the feeding tool body, and the bottom of the feeding tool body is opened.

[0008] Preferably, a hydraulic cylinder is installed on the side of the feeding tool body, and a baffle is installed on the output end of the hydraulic cylinder, and the upper end of the baffle is flush with the lower end of the feeding port.

[0009] Preferably, the adjustment mechanism includes a guide rod, a fixed rod, a through hole and a movable slot, the guide rod is mounted on the end of the baffle away from the hydraulic cylinder, the guide rod is provided with a movable slot, and a limiting rod is inserted into the movable slot;

[0010] The fixing rod is installed on the inner side of the feeding tool body close to the guide rod.

[0011] Preferably, a mounting plate is installed at the other end of the guide rod, a through hole is opened inside the mounting plate, and the fixing rod is arranged in a "Z"-shaped structure, and the fixing rod passes through the inside of the through hole.

[0012] Preferably, the depth of the through hole is greater than the height of the fixing rod, and the upper end of the mounting plate fits with the lower end of the loading port.

[0013] Preferably, the guide rod is arranged in a palm structure, the end of the limiting rod exceeds the side of the guide rod, and the bottom of the limiting rod contacts the top of the fixing rod.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The utility model is provided with a guide rod, a fixed rod and a movable groove. When the guide rod moves to the side, the fixed rod limits the guide rod, and the guide rod slides inside the movable groove. Since the guide rod is a palm structure, the distance between adjacent guide rods changes during the up and down movement of the guide rod. The quartz sand blocked by the guide rod can be dropped by changing the distance between the guide rods. At the same time, large-volume quartz sand can be limited, and larger quartz sand can be crushed later to prevent the larger quartz sand from falling into the magnetic separator and causing a large impact on the machine, thereby protecting the magnetic separator.

[0016] 2. The utility model is provided with a baffle and a mounting plate. The setting of the baffle and the mounting plate limits the quartz sand. The baffle blocks the quartz sand inside the feeding port to prevent the quartz sand from not being screened. The mounting plate can prevent smaller quartz sand from rolling to the crushing roller and prevent more quartz sand from falling on the crushing roller together, thereby protecting the crushing roller. There is no need to wait until all the quartz sand in the magnetic separation feeding tooling has fallen off before putting in the quartz sand, and there is no need to control the amount of quartz sand put in.

[0022] 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.

[0023] See also Figure 1-Figure 4 , the utility model provides the following technical solutions:

[0024] A magnetic separation feeding tool for processing high-purity quartz sand includes a feeding tool body 1 and a feeding port 2. The feeding port 2 is arranged on the feeding tool body 1. A crushing roller 7 is arranged at the bottom of the feeding tool body 1. The bottom of the feeding tool body 1 is an opening. A hydraulic cylinder 3 is installed on the side of the feeding tool body 1, and a baffle 4 is installed at the output end of the hydraulic cylinder 3. The upper end of the baffle 4 is flush with the lower end of the feeding port 2.

[0025] The quartz sand is placed inside the feeding port 2, and the quartz sand inside the feeding port 2 falls above the limit rod 11. The larger volume of quartz sand stays above the limit rod 11, and the smaller volume of quartz sand falls through the gap between the two adjacent limit rods 11. The setting of the baffle 4 and the mounting plate 6 prevents the quartz sand from rolling to both sides and limits the falling direction of the quartz sand. When more quartz sand accumulates on the limit rod 11, the hydraulic cylinder 3 is controlled to move the baffle 4 to the side away from the hydraulic cylinder 3. During the movement of the baffle 4, the mounting plate 6 and the guide rod 5 are driven to move synchronously. During the movement of the baffle 4, the lower end of the feeding port 2 is limited to block the quartz sand.

[0026] An adjusting mechanism is installed inside the feeding tooling body 1. The quartz sand is limited by the adjusting mechanism, and quartz sand of different volumes can be separated. The adjusting mechanism includes a guide rod 5, a fixed rod 8, a through hole 9 and a movable groove 10. The guide rod 5 is installed on the end of the baffle 4 away from the hydraulic cylinder 3. A movable groove 10 is provided on the guide rod 5, and a limiting rod 11 is inserted into the inside of the movable groove 10; the fixed rod 8 is installed on the inner side of the feeding tooling body 1 close to the guide rod 5, and a mounting plate 6 is installed on the other end of the guide rod 5. A through hole 9 is provided inside the mounting plate 6. The fixed rod 8 is arranged in a "Z" shape. The fixed rod 8 passes through the inside of the through hole 9. The depth of the through hole 9 is greater than the height of the fixed rod 8. The upper end of the mounting plate 6 is in contact with the lower end of the feeding port 2.

[0027] When the limit rod 11 moves away from the hydraulic cylinder 3, when the limit rod 11 moves to the turning point position with the fixed rod 8, the limit rod 11 separates from the fixed rod 8, and the limit rod 11 moves downward by its own weight. The limit rod 11 slides inside the moving groove 10 until the limit rod 11 falls down to the horizontal position of the fixed rod 8. After the quartz sand on the limit rod 11 falls completely, the hydraulic cylinder 3 moves in the opposite direction, and the limit rod 11 moves to one side of the hydraulic cylinder 3. When the limit rod 11 moves the fixed rod 8 to the turning point, the fixed rod 8 pushes the limit rod 11, so that the limit rod 11 moves upward synchronously during the horizontal movement. When the limit rod 11 moves upward, the distance between the two adjacent limit rods 11 gradually becomes smaller, so that the distance between the two adjacent limit rods 11 is restored to its original position.

[0028] The guide rod 5 is arranged in a palm structure, the end of the limiting rod 11 exceeds the side of the guide rod 5, and the bottom of the limiting rod 11 contacts the top of the fixing rod 8.

[0029] Due to the structure of the guide rod 5, the distance between adjacent limit rods 11 increases during the downward sliding of the limit rod 11, and the quartz sand engaged above the limit rod 11 falls down through the distance between two adjacent limit rods 11, and the quartz sand falls onto the crushing roller 7. The crushing roller 7 crushes the larger quartz sand, and the crushed quartz sand then enters the magnetic separator, preventing the larger quartz sand from directly acting on the magnetic separator, thereby protecting the magnetic separator.

[0030] Working principle: When using the magnetic separation feeding tooling for high-purity quartz sand processing, first of all, the contents not described in detail in this specification belong to the existing technology well known to professional and technical personnel in this field.
