Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, and in particular to an automatic steel ball feeding device for a mineral processing plant. Background Technology

[0002] In the early stages of the abrasive grinding and processing industry, traditional manual or semi-manual methods were mainly used to add steel balls to meet the continuous replenishment needs of various specifications during production. However, this method has many drawbacks, such as high labor intensity, limitations imposed by on-site conditions, difficulty in maintaining a high filling rate, and a tendency to cause unreasonable steel ball ratios. Currently, most ball mills in my country's mineral processing plants still use manual ball addition, with various methods, such as using a crane to transport steel balls to the feed end of the ball mill and having workers throw them by hand; adding them with shovels; or setting up a ball addition funnel at the feed end to allow the steel balls to roll directly in. The ball addition system is generally once per shift. However, manual ball addition has the disadvantages of inaccurate ball quantity and untimely ball addition, making it difficult to add steel balls according to the optimal ball ratio.

[0003] Later, with technological advancements, devices for automatically adding steel balls to ball mills emerged, such as disc-type, belt-type, and drum-type ball feeders. However, these devices also share common drawbacks, such as ball jamming, clogging, material overflow, and ball leakage. Some ball feeders add agitation devices inside the ball storage bin or vibration devices outside the bin. However, due to the large mass and high friction of the steel balls inside the bin, the motors of the agitation or vibration devices are prone to overload and burn out. Adding vibration devices outside the bin can sometimes actually compact the steel balls inside.

[0004] Therefore, this application proposes an automatic steel ball adding device, which uses a cantilever crane to automatically remove steel balls from the bucket, reducing manual labor. Utility Model Content

[0005] The purpose of this utility model is to solve the problems in the prior art by proposing an automatic steel ball feeding device for a mineral processing plant.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic steel ball feeding device for a mineral processing plant includes a feeding hopper and a base plate disposed below the feeding hopper. The top and bottom of the feeding hopper are open structures. The base plate is used to seal the bottom of the feeding hopper. A connecting rod is vertically fixed at the center of the base plate. The connecting rod slides vertically on the surface of a support assembly. The support assembly is fixed to the top of the feeding hopper. The connecting rod and the feeding hopper are coaxially arranged.

[0008] In some embodiments, the base plate is circular and its diameter is larger than that of the feeding bucket.

[0009] In some embodiments, the base plate includes an arc-shaped plate and a ring fixed to the outer surface of the arc-shaped plate. The arc-shaped plate is an upwardly convex arc, and the ring is perpendicular to the feeding barrel.

[0010] In some embodiments, a plurality of levers are fixed to the surface of the connecting rod, and the plurality of levers are all located inside the feeding barrel.

[0011] In some embodiments, the support assembly includes a support rod fixed to the top of the feeding hopper and adjusting rods that slide at both ends of the support rod.

[0012] In some embodiments, locking bolts for fixing the two adjusting rods are respectively provided on the upper surfaces of both ends of the support rod.

[0013] In some embodiments, baffles are fixed to the lower surfaces of the two adjusting rods, and the baffles are all close to the end of the adjusting rod away from the feeding barrel.

[0014] In some embodiments, the upper end of the connecting rod is fixed with a pull ring that cooperates with the cantilever crane.

[0015] Compared with the prior art, the present invention provides an automatic steel ball feeding device for a mineral processing plant, which has the following beneficial effects.

[0016] 1. This utility model stores steel balls by setting up a feeding bucket and a bottom plate. After the feeding bucket is transported to the top of the feeding port of the mineral processing equipment, it is supported on both sides of the feeding port by a support component, thereby limiting the height of the feeding bucket. By lowering the connecting rod and the bottom plate, the bottom plate is separated from the feeding bucket, so that the steel balls fall into the mineral processing equipment through the gap between the bottom plate and the feeding bucket, thereby achieving the purpose of automatic material discharge, quickly completing the steel ball feeding work, and reducing manual input.

[0017] 2. This utility model, by setting the base plate as an arc-shaped plate and a ring, allows the steel ball to roll from the center of the base plate to the outer ring after the base plate is separated from the feeding bucket. This allows the steel ball to quickly detach from the feeding bucket and avoids irregularly shaped steel balls that have been worn down over time from remaining on the base plate and unable to roll. By setting multiple levers, when the connecting rod and the base plate move downward, the multiple levers are driven to move downward, breaking the force balance when the steel balls are in contact with each other, so that the steel balls can fall smoothly from the feeding bucket.

[0018] Other advantages, objectives and features of this invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be taught from practice of this invention.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figure 1-6 An automatic steel ball feeding device for a mineral processing plant includes a feeding tank 1 and a base plate 2 disposed below the feeding tank 1. The top and bottom of the feeding tank 1 are open structures. The base plate 2 is used to seal the bottom of the feeding tank 1. A connecting rod 3 is vertically fixed at the center of the base plate 2. The connecting rod 3 slides vertically on the surface of a support assembly 4. The support assembly 4 is fixed to the top of the feeding tank 1. The connecting rod 3 and the feeding tank 1 are coaxially arranged. Both ends of the support assembly 4 extend beyond the range of the feeding tank 1. A pull ring 5 that cooperates with a cantilever crane is fixed at the upper end of the connecting rod 3.

[0029] Under normal conditions, the base plate 2 is placed on the ground, and the feeding bucket 1 rests against the surface of the base plate 2, forming a closed-bottom bucket shape. After the worker fills the feeding bucket 1 with steel balls, the bucket is hooked onto the surface of the pull ring 5 by the hook of the cantilever crane. The feeding bucket 1 and the steel balls inside are lifted together by the connecting rod 3 and the base plate 2 and transported to the feeding port 6 of the mineral processing equipment. By setting up the support component 4, when the feeding bucket 1 descends, the support component 4 supports both sides of the feeding port 6 of the mineral processing equipment, thereby limiting the height of the feeding bucket 1. The connecting rod 3 slides down on the surface of the support component 4, and under the weight of the steel balls, the base plate 2 separates from the feeding bucket 1, so that the steel balls fall into the mineral processing equipment through the gap between the base plate 2 and the feeding bucket 1, thereby completing the purpose of automatic material discharge, quickly completing the steel ball feeding work, and reducing manual input.

[0030] Specifically, the base plate 2 is circular, and its diameter is larger than that of the feeding bucket 1.

[0031] It is understandable that by setting the diameter of the base plate 2 to be larger than the diameter of the feeding barrel 1, the base plate 2 can support the bottom of the feeding barrel 1, so that the feeding barrel 1 can rise and fall with the base plate 2.

[0032] Specifically, the base plate 2 includes an arc plate 201 and a ring 202 fixed on the outer surface of the arc plate 201. The arc plate 201 is an upwardly convex arc shape, and the ring 202 is set perpendicular to the feeding barrel 1. The bottom of the arc plate 201 is fixed with cross-shaped reinforcing ribs 203.

[0033] It is understandable that by setting the base plate 2 as an arc plate 201 and a ring 202, the upwardly protruding arc plate 201 facilitates the steel ball to roll from the center of the base plate 2 outward after the base plate 2 is separated from the feeding barrel 1, so that the steel ball can quickly detach from the feeding barrel 1 and avoid the irregular steel ball that has been worn for a long time from staying on the base plate 2 and not being able to roll. By setting the ring 202, the bottom of the feeding barrel 1 is effectively supported.

[0034] Specifically, multiple levers 301 are fixed on the surface of the connecting rod 3, and all the levers 301 are located inside the feeding barrel 1.

[0035] Understandably, in order to prevent the steel balls from piling up and blocking the feed hopper 1, thus preventing the steel balls from falling out of the feed hopper 1, multiple levers 301 are set up. When the connecting rod 3 and the base plate 2 move downward, the multiple levers 301 are driven to move downward, thereby disturbing the multiple steel balls, breaking the force balance when the steel balls are in contact with each other, and allowing the steel balls to fall smoothly from the feed hopper 1.

[0036] Specifically, the support assembly 4 includes a support rod 401 fixed to the top of the feeding barrel 1 and adjusting rods 402 that slide on both ends of the support rod 401. Locking bolts 403 for fixing the two adjusting rods 402 are respectively provided on the upper surface of both ends of the support rod 401.

[0037] It is understandable that by setting up the support rod 401 and the adjusting rod 402, it is convenient to place the feeding bucket 1 on both sides of the feeding port 6 of the mineral processing equipment; by sliding the two adjusting rods 402 at both ends of the support rod 401, it is convenient to adjust the length of the support rod 401 to adapt to the feeding port 6 of different sizes of mineral processing equipment, and when not in use, the adjusting rod 402 can be retracted into the support rod 401 to reduce its space occupation; by setting up the locking bolt 403, it is convenient to limit the position of the adjusting rod 402.

[0038] Specifically, baffles 404 are fixed to the lower surfaces of the two adjusting rods 402 respectively, and the baffles 404 are close to the end of the adjusting rod 402 away from the feeding barrel 1.

[0039] It is understandable that by setting up the baffle 404, when the adjusting rod 402 is attached to the top of the feed port 6 of the mineral processing equipment, the baffle 404 abuts against the inner wall of the feed port 6 of the mineral processing equipment, thereby improving the stability of the feed bucket 1 when it is mounted on the feed port 6 of the mineral processing equipment, thus preventing the feed bucket 1 from vibrating when the steel ball falls, causing the adjusting rod 402 to disengage from the feed port 6 of the mineral processing equipment.

[0040] In this invention, by setting an adjusting rod 402, the length of the support assembly 4 is adjusted to a suitable length according to the size of the feed port 6 of the mineral processing equipment, and fixed by locking bolts 403. By setting a feed bucket 1 and a base plate 2, after steel balls are filled into the feed bucket 1, they are hooked onto the surface of the pull ring 5 by the hook of the cantilever crane. The feed bucket 1 and the steel balls inside are lifted together by the connecting rod 3 and the base plate 2 and transported to above the feed port 6 of the mineral processing equipment. When the feed bucket 1 descends, the support assembly 4 is supported on the surface of the feed bucket 6. Both sides of the feeding port 6 of the mining equipment simultaneously cause the baffle 404 to abut against the inner wall of the feeding port 6 of the mineral processing equipment, improving the stability of the feeding barrel 1 when it is installed at the feeding port 6 of the mineral processing equipment, limiting the height of the feeding barrel 1, and sliding downward on the surface of the support component 4 through the connecting rod 3. Under the weight of the steel ball, the bottom plate 2 separates from the feeding barrel 1, so that the steel ball falls into the mineral processing equipment through the gap between the bottom plate 2 and the feeding barrel 1, completing the purpose of automatic material discharge, quickly completing the steel ball feeding work, and reducing the input of manual labor.
