Description

Technical Field

[0001] The utility model relates to the technical field of ball mills, in particular to a ball mill with a feeding dust prevention device. Background Art

[0002] Ball mill is a key equipment for crushing materials after they are broken. It is widely used in mining, building materials, chemical industry and other fields to grind various ores, cement, ceramics and other materials.

[0003] The working principle of the ball mill is as follows: the material is fed into the first chamber of the mill evenly through the feeding device through the hollow feed shaft spiral. The chamber has a stepped liner or a corrugated liner and is filled with steel balls of various specifications. The rotation of the cylinder generates centrifugal force, which brings the steel balls to a certain height and then falls, producing a heavy impact and grinding effect on the material. After the material is coarsely ground in the first chamber, it enters the second chamber through a single-layer partition plate. The chamber is inlaid with a flat liner and contains steel balls to further grind the material. The powder is discharged through the discharge arm plate, completing the grinding operation.

[0004] During the operation of the wet ball mill, an appropriate amount of water will be added at the feed inlet as the material enters, so that the material contains a certain amount of moisture. At this time, the temperature of the grinding process will not rise, the overall grinding efficiency is high, and dust generation during feeding can be avoided. However, in this process, the material powder that has reached the required amount in the material will still be driven by the water flow into the ball mill. Such repeated work leads to power waste. Based on this, in order to achieve the purpose of pre-separating the material powder that has reached the required amount in the material, a ball mill with a feeding dust prevention device is provided.

[0032] The dust removal unit is used to spray water to remove dust from the outside of the filter hopper 104 and to pre-separate the material powder that has reached the required amount;

[0033] The conveying unit is used to transport the separated material powder to the next process;

[0034] The dust removal unit includes a fixing seat 201, an annular seat 202, an arc-shaped blocking block 203, a spray hole 204, and a water inlet pipe 205;

[0035] The fixed seat 201 is fixed to one end of a rotating support seat 101 and is located below the feed hopper 103 and the filter hopper 104. The annular seat 202 is fixed to the top of the fixed seat 201 and is distributed outside the filter hopper 104. The arc-shaped blocking blocks 203 are symmetrically fixed to the bottom of both ends of the outer wall of the annular seat 202.

[0036] The inner side of the upper half of the arc-shaped blocking block 203 is a cavity structure, the spray hole 204 is opened at the inner top of the arc-shaped blocking block 203, and the water inlet pipe 205 is fixed to one side of the outer wall of the arc-shaped blocking block 203, and the spray hole 204, the water inlet pipe 205 and the cavity of the arc-shaped blocking block 203 are conductive;

[0037] Water is sprayed through the water inlet pipe 205, the cavity of the arc-shaped blocking block 203, and the spray hole 204 to realize water spray dust removal on the filter bucket 104. The material powder that has reached the required amount flows through the leakage hole on the filter bucket 104 and falls into the bottom of the fixed seat 201, realizing the separation and collection of the material powder.

[0038] The conveying unit includes a conveying pipe 206, a driven gear 207, and a spiral blade 208;

[0039] The delivery pipe 206 is rotatably connected to the inner sides of the two rotating support bases 101 and completely passes through the two rotating support bases 101, and passes through an arc-shaped blocking block 203 to the inner side of the arc-shaped blocking block 203. The rotating support base 101 is provided with a rotating slot 106 for the delivery pipe 206 to rotate and pass through.

[0040] The driven gear 207 is fixed to the outside of the delivery tube 206 and meshes with the driving gear 105;

[0041] The spiral blade 208 is fixed to the inner side of the delivery pipe 206 and passes through one end of the delivery pipe 206 to the inner side of the arc-shaped blocking block 203;

[0042] The driving gear 105 rotates to drive the driven gear 207, the conveying pipe 206, and the spiral blade 208 to rotate synchronously. The rotating arc-shaped straight groove 209 is used to drive the material powder mixture into the conveying pipe 206 and convey it to the next process.

[0043] In this embodiment, it should be noted that when the ball mill 1 is in use, a corresponding driving device is installed. The output end of the driving device is connected to a driving gear that meshes with the driving gear 105. The driving gear is driven to rotate, and the driving gear drives the driving gear 105 to rotate. The driving gear 105 drives the ball mill cylinder 102 to rotate to perform the ball milling operation. The ball mill is provided with corresponding steel balls. Since this structure is a prior art structure, it is not described in detail.

[0044] During the operation of the ball mill cylinder 102, the material is transported to the interior of the filter hopper 104 through an external transport device (for example, a conveyor belt), and a water pump connected to the water inlet pipe 205 is simultaneously started (it should be noted that the water pump is connected to the external water tank). At this time, water is transported to the interior of the water inlet pipe 205 by the water pump, and is sprayed out to the outside of the filter hopper 104 through the spray hole 204, and enters the inside of the filter hopper 104 through the filter holes of the filter hopper 104, thereby flushing the material. Among them, the material powder that has reached the required amount will pass through the filter holes at the bottom of the filter hopper 104 with the water flow and fall into the bottom of the inner side of the annular seat 204, thereby separating and collecting the material powder that has reached the required amount (it should be additionally noted that the filter hopper 104 rotates synchronously with the ball mill cylinder 102, which can prevent the filter hopper 104 from being blocked);

[0045] At the same time, the rotating driving gear 105 can drive the driven gear 207 to rotate, and the driven gear 207 drives the conveying pipe 206 and the spiral blade 208 to rotate synchronously. The rotating spiral blade 208 can drive the material powder mixture inside the annular seat 204, so that it enters the interior of the conveying pipe 206 and is transported forward along the trajectory of the conveying pipe 206 to the next process;

[0046] Through the coordination of the above multiple parts, the material powder that has reached the required amount can be pre-separated, thus avoiding repeated work and further improving the working efficiency of the ball mill.

[0047] Please refer to Figures 1 to 5An arc-shaped straight groove 209 is formed on the bottom of the inner wall of the arc-shaped blocking block 203 , and the portion of the spiral blade 208 protruding from one end of the conveying pipe 206 is distributed inside the arc-shaped straight groove 209 .

[0048] In this embodiment, the arc-shaped straight groove 209 provides space for the rotation of the spiral blade 208, and at the same time enables the material powder mixture to be better concentrated and taken away by the rotating spiral blade 208. The rotating spiral blade 208 can also stir the mixture to avoid powder deposition.

[0049] Please refer to Figures 1 to 5 There are multiple groups of spray holes 204 arranged in the horizontal direction, each group of spray holes 204 includes multiple spray holes 204 evenly distributed along an arc trajectory, and the distribution trajectory angle of each group of spray holes 204 is greater than one hundred and eighty degrees.

[0050] In this embodiment, this structure and the rotation of the filter bucket 104 can achieve all-round flushing of the filter bucket 104, thereby preventing the filter bucket 104 from being blocked.

[0051] At the same time, the spraying area of ​​the spray hole 204 is larger than the area where the water flows downward through the filter hole, so that a part of the water flow inside the filter bucket 104 can be exposed and enter the ball mill cylinder 102 along with the material, thereby realizing wet ball milling operation.

[0052] Please refer to Figures 1 to 5 The inner wall diameter of the arc-shaped blocking block 203 matches the outer wall diameter of the feed hopper 103 , and the inner wall of an arc-shaped blocking block 203 close to the rotating support seat 101 fits with the outer wall of the feed hopper 103 .

[0053] In this embodiment, the arc-shaped blocking block 203 blocks both ends of the bottom of the annular seat 202, thereby providing a collection space for the material powder mixture. It should also be noted that a seal is provided at the contact portion between the conveying pipe 106 and the arc-shaped blocking block 203 to avoid leakage.

[0054] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
