Technical Field
[0001] The utility model relates to the field of ball mills for molybdenum tailings, in particular to mixing equipment for molybdenum tailings production. Background Art
[0002] Molybdenum tailings are waste products after molybdenum mining, and their reuse in the form of cement has become an important direction of resource recycling. By adding appropriate amounts of molybdenum tailings into cement production, they can not only improve the crack resistance of cement, but also reduce production costs, achieving a win-win situation in economic and environmental benefits. However, the processing technology of molybdenum tailings is relatively difficult, and the amount of addition needs to be strictly controlled to ensure the quality of cement.
[0003] The inventors of this application have found the following problems in practical use:
[0004] In order to enhance the commercial value of molybdenum tailings, they are usually used as a mixed material for pre-prepared cement. After fine processing such as crushing and grinding, they can reach the particle size standard required for cement production. In this process, the ball mill plays a key role. It can not only grind the molybdenum tailings, but also mix them with other cement raw materials. However, traditional ball mills mostly use spiral blade feeding when feeding. Faced with molybdenum tailings with larger particles, the spiral blades are easily worn and need frequent maintenance and replacement. The problem is that these spiral blades are often fixed to the inner wall of the drum at the ball mill inlet by welding, which greatly increases the difficulty of maintenance and reduces the processing efficiency of molybdenum tailings. Improvements are urgently needed to improve overall production efficiency.
[0005] Therefore, it is necessary to provide a molybdenum tailings production mixing equipment to solve the above technical problems. Utility Model Content
[0006] The technical problem to be solved by the present invention is that the spiral blades of the traditional ball mill are welded and fixed, and rotate synchronously with its drum, which reduces the convenience of maintenance of the spiral conveying blades. In view of the above-mentioned defects of the prior art, a mixing equipment for molybdenum tailings production is provided.
[0007] To achieve the above-mentioned purpose, the technical solution of the utility model is: a mixing equipment for molybdenum tailings production, comprising a base frame, a ball mill drum is arranged on the top of the base frame through a rotating assembly, and a detachable feeding mechanism is arranged on one side of the ball mill drum, the feeding mechanism comprises a feed barrel, a spiral blade is arranged at the central axis of the feed barrel, and a servo motor is installed on one side and is transmission-connected to the spiral blade, a discharge barrel is arranged on the top of the feed barrel, the end of the spiral blade is a protruding structure, and a support frame is arranged below the feed barrel.
[0008] By adopting the technical scheme, when the spiral blade needs to be repaired or replaced, the operator only needs to move the support frame to make the spiral blade separate from the inner side of the connecting cylinder, thereby realizing the detachable connection between the spiral blade and the ball mill, avoiding the complicated process of disassembling a large number of components to repair or replace the spiral blade in the traditional way, and greatly improving the work efficiency.
[0009] Further arrangement, the lower side of the support frame is provided with four groups of rollers for moving and disassembling the feeding mechanism.
[0010] By adopting the technical scheme, when the equipment needs to be maintained or repaired, the operator can easily move the feeding mechanism through the rollers without complicated disassembly process, thereby saving a lot of time and effort.
[0011] Further arrangement, the rotating assembly comprises a connecting cylinder, a fixed ring is fixedly arranged on the outer side of the connecting cylinder, the connecting cylinder is fixedly connected with the ball mill cylinder, and support rollers are arranged on the top of the bottom frame on both sides and abut against the fixed ring.
[0012] By adopting the technical scheme, the fixed connection between the connecting cylinder in the rotating assembly and the ball mill cylinder ensures stable transmission therebetween, avoiding equipment failure caused by loose connection.
[0013] Further arrangement, the protruding structure of the spiral blade is inserted with the connecting cylinder for conveying the raw materials into the inside of the ball mill cylinder through the connecting cylinder.
[0014] By adopting the technical scheme, the insertion of the protruding structure of the spiral blade and the connecting cylinder realizes efficient and continuous conveying of the raw materials, and the insertion structure ensures that the raw materials will not leak during conveying, improving the utilization rate of the raw materials.
[0015] Further arrangement, the end of the support frame is in a stepped sleeve structure with the connecting cylinder, and the contact surfaces are not in contact.
[0016] By adopting the technical scheme, the connection between the support frame and the connecting cylinder is more stable, avoiding equipment shaking or tilting caused by loose connection, and meanwhile, the design that the contact surfaces are not in contact reduces friction and wear, prolonging the service life of the equipment.
[0017] Further arrangement, an opening is formed on one side of the top of the feeding cylinder, and part of the spiral blade is exposed to the outside.
[0018] By adopting the above technical solution, the opening exposes part of the spiral blade to the outside world, which makes it convenient for the operator to conduct intuitive inspection and maintenance of the spiral blade. During the operation of the equipment, the operator can observe the working status of the spiral blade through the opening at any time, and promptly discover and deal with possible problems.
[0019] It is further provided that two sets of mounting plates are fixedly provided on one side of the support frame, the mounting plates are bolted to the base frame, a reduction gearbox and a drive motor are installed on one side of the ball mill drum, and a discharge port is formed.
[0020] By adopting the above technical solution, the two sets of mounting plates fixed on one side of the support frame and the bolt mounting design of the base frame enable the feeding mechanism to be firmly fixed on the equipment, avoiding loosening or displacement caused by vibration or impact.
[0021] Compared with the related art, the mixing equipment for molybdenum tailings production provided by the present invention has the following beneficial effects:
[0022] The utility model provides a mixing device for molybdenum tailings production. Through the design of the feeding mechanism and the roller, the support frame can be easily moved, thereby driving the feeding mechanism and the spiral blade connected thereto to move together. When the spiral blade needs to be repaired or replaced, the spiral blade can be separated from the inner side of the connecting cylinder by moving the support frame, so that it is completely exposed to the outside world. This greatly simplifies the disassembly process of the spiral blade and avoids the tedious steps of disassembling a large number of parts in the traditional method.
[0023] The utility model provides a mixing device for molybdenum tailings production, which adopts a mounting plate to ensure that a feeding mechanism can be firmly fixed on the equipment. By tightening the bolts, a firm connection is formed between the mounting plate and the base frame, so that the feeding mechanism will not loosen or move during the operation of the equipment. This is very important for ensuring the stable operation of the equipment, especially when the equipment is subjected to vibration or impact, and can effectively prevent the feeding mechanism from falling off or being damaged.

DETAILED DESCRIPTION
[0029] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. The drawings show typical embodiments of the present application. EMBODIMENT
[0030] As Figure 1 shown, a kind of mixed equipment for molybdenum tailings production of the present application, including underframe 1, the top of underframe 1 is rotationally provided with ball mill roller 2 by rotating assembly 4, and the side of ball mill roller 2 is provided with detachable feeding mechanism 5, feeding mechanism 5 includes feed cylinder 502, and spiral blade 504 is arranged at the central axis of feed cylinder 502, and servo motor 505 is installed on one side, and is drivingly connected with spiral blade 504, and discharge cylinder 506 is communicatively arranged at the top of feed cylinder 502, the end of spiral blade 504 is in convex structure, support frame 501 is arranged below feed cylinder 502, when needing to overhaul or replace spiral blade 504, operator only needs to move support frame 501, so that spiral blade 504 is separated from the inner side of connecting cylinder 401, to realize the detachable connection between spiral blade 504 and ball mill, avoid the cumbersome process of needing to disassemble a large number of components to overhaul or replace spiral blade 504 in traditional mode, greatly improve work efficiency, at the same time, spiral blade 504 is completely exposed to outside, which provides great convenience for the overhaul and replacement operation of operator, and operator can directly check, clean or replace spiral blade 504 exposed to outside without being limited by the internal space of equipment.
[0031] As Figure 1 , Figure 3 shown, four groups of rollers 507 are installed below support frame 501, for moving and disassembling feeding mechanism 5, when needing to maintain or overhaul equipment, operator can easily move feeding mechanism 5 by roller 507 without complex disassembly process, so that a lot of time and effort are saved, and at the same time, the layout adjustment of equipment on production line becomes more flexible, equipment position can be quickly adjusted according to production demand, production efficiency and flexibility are improved.
[0032] As Figure 4As shown, the rotating assembly 4 includes a connecting cylinder 401, and a fixed ring 402 is fixedly arranged on the outer side of the connecting cylinder 401. The connecting cylinder 401 is fixedly connected with the ball mill roller 2. The top of the chassis 1 is provided with a supporting roller 403 on both sides, and the supporting roller 403 abuts against the fixed ring 402. The fixed connection between the connecting cylinder 401 in the rotating assembly 4 and the ball mill roller 2 ensures stable transmission between the two, avoiding equipment failure caused by loose connection. At the same time, the abutting design of the fixed ring 402 and the supporting roller 403 provides stable support for the ball mill roller 2, effectively reducing the vibration and noise of the equipment during operation, improving the stability and service life of the equipment, and enabling the equipment to operate continuously and stably for a long time, providing a strong guarantee for efficient production.
[0033] As shown in Figure 3 , Figure 4 , the protruding structure of the spiral blade 504 is inserted with the connecting cylinder 401, for conveying the raw materials into the interior of the ball mill roller 2 through the connecting cylinder 401. The insertion of the protruding structure of the spiral blade 504 with the connecting cylinder 401 realizes efficient and continuous conveying of the raw materials. This insertion structure ensures that the raw materials will not leak during conveying, improving the utilization rate of the raw materials. At the same time, the protruding structure enables the spiral blade 504 to generate greater thrust on the raw materials during rotation, facilitating the pushing of the raw materials into the interior of the ball mill roller 2 through the connecting cylinder 401, improving the production efficiency, and facilitating disassembly and installation.
[0034] As shown in Figure 3 , Figure 4 , the end of the supporting frame 501 is in a stepped sleeve structure with the connecting cylinder 401, and the contact surfaces are not in contact with each other, so that the connection between the supporting frame 501 and the connecting cylinder 401 is more stable, avoiding equipment shaking or tilting caused by loose connection. At the same time, the design that the contact surfaces are not in contact with each other reduces friction and wear, prolonging the service life of the equipment. In addition, this structure also makes it easier to install and disassemble the supporting frame 501, reduces maintenance cost, improves the maintainability and usability of the equipment. In some other embodiments, bearings can be assembled at the sleeve joint to reduce friction damage during operation.
[0035] As shown in Figure 3 , Figure 4As shown, an opening 503 is formed on one side of the top of the feed barrel 502, and part of the spiral blade 504 is exposed to the outside. The opening 503 exposes part of the spiral blade 504 to the outside, which is convenient for the operator to visually inspect and maintain the spiral blade 504. During the operation of the equipment, the operator can observe the working status of the spiral blade 504 through the opening 503 at any time, and promptly discover and deal with possible problems. At the same time, it also makes it easier to replace the spiral blade 504 without disassembling the entire feed barrel 502, thereby reducing the difficulty and cost of maintenance. Example
[0036] like Figure 3 As shown, two sets of mounting plates 508 are fixedly provided on one side of the support frame 501, and the mounting plates 508 are bolted to the base frame 1. A reduction gearbox 301 and a drive motor 302 are installed on one side of the ball mill drum 2, and a discharge port 6 is formed. The two sets of mounting plates 508 fixed on one side of the support frame 501 and the bolt installation design of the base frame 1 enable the feeding mechanism 5 to be firmly fixed on the equipment, avoiding loosening or displacement caused by vibration or impact. At the same time, the reduction gearbox 301 and the drive motor 302 installed on one side of the ball mill drum 2 provide a stable power source for the rotation of the drum, ensuring the normal operation of the equipment.
[0037] During implementation, if the spiral blade 504 needs to be repaired or replaced, first, the bolts connecting the mounting plate 508 to the base frame 1 are removed, and then the support frame 501 can be moved by the roller 507 to cause the spiral blade 504 to be separated from the inner side of the connecting cylinder 401, so that the spiral blade 504 is completely exposed to the outside world. In this way, the spiral blade 504 and the ball mill are made into a detachable structure, and the spiral blade 504 is exposed to the outside world, which facilitates the subsequent repair and replacement operations of the spiral blade 504 and improves the convenience of repair and replacement of the spiral blade 504.
[0038] First, the molybdenum tailings and cement raw materials that need to be processed are placed into the inner side of the discharge barrel 506. At the same time, the spiral blade 504 is driven to rotate by the servo motor 505 on one side, thereby driving the molybdenum tailings and other raw materials inside to move in position until the raw materials are transported to the inside of the ball mill drum 2 through the connecting barrel 401. At the same time, the drive motor 302 on one side drives the ball mill drum 2 to rotate, and cooperates with the internal grinding balls to grind the raw materials until they are ground to the required specifications and then discharged from the discharge port 6 on one side, completing the mixed processing of the molybdenum tailings and other raw materials.
[0039] The advantages of this technical solution in practical applications include but are not limited to the following:
[0040] 1. Move the support frame to separate the spiral blade from the connecting tube, which not only realizes the detachable connection between the spiral blade and the ball mill, but also makes the spiral blade completely exposed to the outside world, greatly improving the convenience of maintenance and replacement;
[0041] 2. The bolt installation between the mounting plate and the base frame enables the feeding mechanism to be firmly fixed on the equipment, avoiding loosening or displacement caused by vibration or impact.
[0042] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
