Description

Technical Field

[0001] The utility model relates to the technical field of production equipment, and particularly relates to an iron removal device for the discharge port of a ball mill. Background Technique

[0002] A ball mill is a key device for crushing materials and then pulverizing them. A certain number of steel balls or ceramic balls are loaded into the cylinder body of the ball mill as grinding media. During the rotation of the cylinder body, the grinding media impact and crush the materials, and at the same time, play a certain grinding role.

[0003] When the existing ball mill operates, materials containing iron substances or iron filings may be mixed. Under the action of centrifugal force and friction, together with the steel balls or ceramic balls installed in the cylinder, they reach a certain height along with the cylinder body. When their own gravity is greater than the centrifugal force, they break away from the inner wall of the cylinder body and fall or roll down by projection. The steel balls break the materials due to the impact force, and may further release impurities such as iron substances or iron filings in the materials. Larger-sized steel fragments and iron impurities are separated by the cylinder sieve, and smaller-sized steel fragment and iron impurities will sink to the bottom of the chute. These small-sized steel ball fragments will have an adverse impact on the subsequent processes.

[0004] In the patent document with the publication number CN218423355U, an iron removal device for the discharge port of a ball mill is disclosed. By hierarchically arranging magnetic rods in the shell, the iron filings in the iron-filing-containing materials passing through the shell are adsorbed by the magnetic rods, and then the iron filings in the materials are removed. The magnetic rods form a magnetic structure body, so that the magnetic rods in the hierarchy are arranged neatly, and it is convenient to take out the magnetic structure body from the shell for iron filing recovery and cleaning.

[0005] However, when this iron removal device for the discharge port of a ball mill is in use, the iron filings adsorbed on the magnetic rods need to be cleaned frequently. Otherwise, the adsorption effect will be reduced, and the frequent cleaning will reduce the working efficiency and affect the production quality. Therefore, an iron removal device for the discharge port of a ball mill needs to be proposed. Content of the Utility Model

[0027] On the basis of the first embodiment, a screening mechanism is arranged inside the screening box 1. The screening mechanism includes a fixing frame 101, a screening plate 102, an upper baffle 103, a lower baffle 104, a connecting rod 105, a connecting plate 106, a first motor 107, rollers 108, a blanking inclined plate 109 and a collection box 110. The fixing frame 101 is fixedly connected to the inner wall of the screening box 1. An installation groove is formed through one side of the screening box 1, and the fixing frame 101 is fixedly connected to the bottom of the inner wall of the installation groove. The screening plate 102 is movably connected to the top of the fixing frame 101. The upper baffle 103 is fixedly connected to the top of the screening plate 102. The lower baffle 104 is fixedly connected to the bottom of the screening plate 102. The lower baffle 104 is to prevent the material from falling and some splashing to get stuck in the rollers 108. The connecting rod 105 is rotatably connected to one side of the upper baffle 103. The connecting plate 106 is rotatably connected to one side of the connecting rod 105. The first motor 107 is arranged on the top of the fixing frame 101. The rollers 108 are arranged at the bottom of the screening plate 102. Four rollers 108 are evenly distributed on both sides of the bottom of the screening plate 102 respectively. The rollers 108 are to reduce the friction when the screening plate 102 moves. The blanking inclined plate 109 is fixedly connected to the inner wall of the screening box 1. The collection box 110 is arranged at the bottom left of the fixing frame 101. When the material enters the screening box 1 from the feeding port 3, the iron filings with larger volume will pass through the screening plate 102 and then be screened out. The first motor 107 drives the connecting plate 106 to rotate, and then drives the connecting rod 105 to rotate. The screening plate 102 shows a linear reciprocating motion, which can avoid the accumulation of iron filings on the top of the screening plate 102 causing the screening plate 102 to be blocked, and can also make the iron filings on the top of the screening plate 102 be shaken and pushed into the collection box 110 for collection.

[0028] A feeding port 3 is arranged at the top of the screening box 1. A discharge port 4 is arranged at the bottom of the iron removal box 2. Four feet 5 are fixedly connected to the bottom of the iron removal box 2, and the feet 5 are evenly distributed at the bottom of the iron removal box 2.

[0029] Working principle:

[0030] First of all, through the arranged screening mechanism, the equipment is installed at the discharge port of the ball mill. When the material enters the screening box 1 from the feeding port 3, the iron filings with larger volume will pass through the screening plate 102 and then be screened out. After starting the first motor 107, it drives the connecting plate 106 to rotate, and then drives the connecting rod 105 to rotate. At this time, the screening plate 102 shows a linear reciprocating motion, which can avoid the accumulation of iron filings on the top of the screening plate 102 causing the screening plate 102 to be blocked, and can also make the iron filings on the top of the screening plate 102 be shaken and pushed into the collection box 110 for collection.

[0031] Furthermore, the screened material will fall into the iron removal box 2 through the two blanking inclined plates 109.

[0032] Further, by means of the iron removal mechanism provided, after the second motor 204 is started, it drives the rotation of two meshing gears inside the gear box 203. At this time, the first magnetic roller 201 and the second magnetic roller 202 rotate counterclockwise and clockwise respectively. The material output from the screening box 1 to the iron removal box 2 will pass through the first magnetic roller 201 and the second magnetic roller 202, and the iron filings inside the material will be magnetically adsorbed by the first magnetic roller 201 and the second magnetic roller 202.

[0033] Furthermore, the spring 208 in the compressed state will generate a resilience force under the action of its own restoring force and act on one side of the connecting block 206, so that the scraper 209 fixedly connected to one side of the connecting block 206 is pressed against the outer surface of the first magnetic roller 201. When the first magnetic roller 201 rotates counterclockwise, the iron filings adsorbed on its surface will be scraped off by the scraper 209. Working in this way, the iron filings will accumulate on the top of the scraper 209, facilitating the cleaning by the staff.
