Description

Technical Field

[0001] This utility model relates to the field of mining engineering technology, and in particular to an anti-clogging diversion type ball mill feeder used in fluorite flotation. Background Technology

[0002] In fluorite flotation production, the ball mill is a key grinding equipment. The stability of its feeding process directly affects the production efficiency. As the core component connecting the raw material conveying and the ball mill, the feeder needs to ensure the orderly conveying of raw materials and avoid production line interruptions due to poor conveying. This is of great significance for ensuring the continuous and efficient operation of the fluorite flotation process.

[0003] In the existing technology, ball mill feed is mostly carried directly through simple pipes to transport fluorite raw materials. During operation, the raw materials enter through the feed pipe and flow to the ball mill by their own gravity or simple pushing mechanism. Some feeding devices are equipped with fixed screens to initially filter impurities, but the screens are mostly statically set and are not equipped with active auxiliary structures.

[0004] The existing technology has the following drawbacks: the existing feeding method has the problem of easy accumulation and blockage of raw materials. The fluorite raw material particles are of uneven size. During static conveying and screening, the particles are easy to accumulate in the pipes or screens, which leads to blockage of the feed channel. Frequent manual cleaning is required, which not only increases labor costs, but also interrupts the production process and reduces the overall flotation efficiency. Therefore, an anti-blockage diversion type ball mill feeder for fluorite flotation is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an anti-clogging diversion type ball mill feeder for fluorite flotation, aiming to improve the problem of raw materials easily clogging in the feed pipe in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a clogging-resistant, diverting ball mill feeder for fluorite flotation, comprising a feed pipe, a ball mill disposed at the left end of the feed pipe, a support plate fixedly connected to the top end of the feed pipe, a motor I fixedly connected to the top end of the support plate, a rotating rod fixedly connected to the output end of the motor I, a connecting rod fixedly connected to the inner wall of the feed pipe, a screening screen slidably connected through the outer wall of the connecting rod, a movable mechanism disposed at the top end of the screening screen, a motor II fixedly connected to the outer wall of the feed pipe via a support frame, a bracket disposed at the bottom of the feed pipe, a distributor fixedly connected to the output end of the motor II, an extrusion rod fixedly connected to the lower outer wall of the rotating rod, and a dispersing component disposed on the inner wall of the rotating rod; The active mechanism includes a sleeve, which is fixedly connected to the top of the screening screen, and the inner wall of the sleeve is provided with an extrusion groove.

[0007] As a further description of the above technical solution: The dispersing assembly includes a stirring rod, which is inserted into the inner wall of a rotating rod, and a fixing bolt is threaded onto the inner wall of the stirring rod.

[0008] As a further description of the above technical solution: The outer wall of the screening screen is in contact with the inner wall of the feed pipe.

[0009] As a further description of the above technical solution: The rotating rod is movably connected to the inner wall of the sleeve, and the extrusion rod is slidably connected to the inner wall of the extrusion groove.

[0010] As a further description of the above technical solution: The extrusion groove is wavy in shape, and the connecting rod is L-shaped.

[0011] As a further description of the above technical solution: The rotating rod is rotatably connected to the inner wall of the support plate, and the feeder is rotatably connected to the inner wall of the feed pipe.

[0012] As a further description of the above technical solution: The fixing bolt is threaded onto the top of the rotating rod.

[0013] This utility model has the following beneficial effects: 1. In this utility model, after adding ore raw materials, the dual motors are turned on. The motor drives the rotating rod and the extrusion rod to rotate, which, together with the extrusion groove, makes the screening screen move back and forth vertically. This can screen the fluorite raw materials, keep the raw materials active, and avoid accumulation and blockage. After screening, the raw materials can be divided into multiple groups by the distributor blades and evenly fed into the ball mill for grinding.

[0014] 2. In this utility model, the rotating rod drives the stirring rod, and the stirring rod impacts and disperses the fluorite raw material, further preventing accumulation and ensuring smooth feeding. The stirring rod is fixed by a fixing bolt. When replacing it, you only need to manually unscrew the fixing bolt, take out the old rod, insert the new rod, and tighten the fixing bolt. The operation is simple and can reduce the downtime maintenance time of the flotation production line. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-3 This utility model provides an embodiment of an anti-clogging, diversion-type ball mill feeder for fluorite flotation, comprising a feed pipe 1, which serves as the conveying channel for fluorite ore into a ball mill 2. The diameter of the feed pipe 1 is designed to be adapted to the processing capacity of the ball mill 2. The ball mill 2 is located at the left end of the feed pipe 1, and the ball mill 2 and the feed pipe 1 are sealed together by a flange structure to ensure that the ore does not leak during conveying. A support plate 3 is fixedly connected to the top end of the feed pipe 1. The support plate 3 is made of high-strength alloy steel plate and is welded together. The feed pipe 1 is securely connected to the support plate 3, providing support for the motor above. The top of the support plate 3 is fixedly connected to the motor 4, and the output end of the motor 4 is fixedly connected to the rotating rod 5. The inner wall of the feed pipe 1 is fixedly connected to the connecting rod 11, which is symmetrically distributed on both sides of the inner wall of the feed pipe 1. It plays a guiding and supporting role for the screening screen 7. The outer wall of the connecting rod 11 is slidably connected to the screening screen 7. The screening screen 7 is made of wear-resistant stainless steel, and the mesh size can be selected according to the particle size requirements of the fluorite ore. The top of the screening screen 7 is equipped with a movable mechanism.

[0019] Reference Figures 1-3 The outer wall of the feed pipe 1 is fixedly connected to the motor 14 via a support frame. The support frame is made of angle steel and has sufficient load-bearing capacity to firmly fix the motor 14 to the outer wall of the feed pipe 1. A bracket 13 is set at the bottom of the feed pipe 1, which provides bottom support for the entire feeder and keeps the feeder in a horizontal and stable state. The output end of the motor 14 is fixedly connected to the distributor 12. The distributor 12 adopts a ring-shaped blade structure and rotates to distribute materials through the drive of the motor 14. The lower outer wall of the rotating rod 5 is fixedly connected to the extrusion rod 8. The inner wall of the rotating rod 5 is provided with a dispersing component. The movable mechanism includes a sleeve 9, which is fixedly connected to the top of the screening screen 7. The sleeve 9 and the screening screen 7 are detachably connected by bolts for easy maintenance and replacement. The inner wall of the sleeve 9 is provided with an extrusion groove 10.

[0020] Reference Figure 2 and Figure 6 The dispersing component includes a stirring rod 6, which is inserted into the inner wall of a rotating rod 5. The rotating rod 5 has a slot that matches the stirring rod 6. A fixing bolt 15 is threaded onto the inner wall of the stirring rod 6 and threaded onto the top of the rotating rod 5. The fixing bolt 15 securely connects the stirring rod 6 and the rotating rod 5 by tightening, preventing the stirring rod 6 from loosening and falling off during the stirring process.

[0021] Reference Figures 3-5 The outer wall of the screening screen 7 is in contact with the inner wall of the feed pipe 1. The rotating rod 5 is movably connected to the inner wall of the sleeve 9. A wear-resistant bushing is provided between the rotating rod 5 and the sleeve 9 to reduce wear during relative movement. The extrusion rod 8 is slidably connected to the inner wall of the extrusion groove 10. The sliding of the extrusion rod 8 in the extrusion groove 10 is converted into the up-and-down movement of the sleeve 9, which in turn drives the screening screen 7 to vibrate. The shape of the extrusion groove 10 is wavy. This shape design enables the extrusion rod 8 to generate periodic up-and-down driving force when rotating, realizing the reciprocating vibration of the screening screen 7. The shape of the connecting rod 11 is L-shaped. The L-shaped structure not only ensures the connection strength with the inner wall of the feed pipe 1, but also provides a guiding effect for the sliding of the screening screen 7. The rotating rod 5 is rotatably connected to the inner wall of the support plate 3. The distributor 12 is rotatably connected to the inner wall of the feed pipe 1. A sealing element is provided at the contact part between the distributor 12 and the feed pipe 1 to prevent the ore from leaking from the gap, while ensuring the smooth rotation of the distributor 12.

[0022] Working principle: When ore raw materials need to be fed into the ball mill 2, the operator can add ore raw materials into the feed pipe 1, and then turn on motor 4 and motor 14. Motor 4 will drive the rotating rod 5 to start rotating, and the rotating rod 5 will drive the extrusion rod 8 to start rotating. Through the cooperation of the extrusion rod 8 and the extrusion groove 10, the screening screen 7 can move back and forth vertically to screen the raw materials, so that the raw materials that meet the size fall down. At the same time, the raw materials are kept in an active state to avoid the accumulation of raw materials and blockage. After screening, the raw materials will fall into the multiple sets of blades of the distributor 12. Through the separation of the blades, the raw materials are divided into multiple groups and sent into the ball mill 2 for grinding.

[0023] When the rotating rod 5 rotates, it will drive the stirring rod 6 to rotate as well. The stirring rod 6 impacts and breaks up the raw materials to prevent them from piling up. When the stirring rod 6 needs to be replaced, manually unscrew the fixing bolt 15. When the fixing bolt 15 separates from the groove on the rotating rod 5, manually remove the stirring rod 6. Then, align the new stirring rod 6 and insert it into the groove on the rotating rod 5. Manually tighten the fixing bolt 15 to complete the positioning of the stirring rod 6.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
