Description

Technical Field

[0001] The utility model relates to the technical field of ball mills, in particular to a discharging and filtering device for a ball mill. Background Art

[0002] A ball mill uses the rotation of the cylinder to drive the internal steel balls to roll, toss, collide, and rub, etc., to crush and grind the materials into finer particles. After the ball milling is completed, the powder needs to be poured out. Patent 202220799004.0 discloses a filtering component for the discharging port of a ball mill, which avoids the steel balls from being poured out with the materials by setting a filter screen at the discharging port. However, in the actual operation process, the ball milling medium steel balls will become smaller and smaller due to long-term wear. When the diameter of the steel balls is smaller than the gap of the discharging screen mesh, they will mix into the abrasive discharged below through the screen gap. In actual production, the steel balls mixed into the fine powder abrasive are removed by manual sieving. However, this production method not only has low efficiency, but also inevitably causes dust pollution and material waste, and further improvement is urgently needed. Summary of the Utility Model

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a discharging and filtering device for a ball mill that can automatically screen during ball mill discharging to completely remove the fine steel balls mixed into the abrasive.

[0004] The purpose of the utility model is realized by the following technical solutions: A discharging and filtering device for a ball mill, including a square-round pipe joint, a quick clamp, a sieve cylinder, a sieve mesh, and a micro vibration motor. The upper inlet of the square-round pipe joint is square and is provided with an outward-turned flange. The lower outlet of the square-round pipe joint is a circular flanged pipe. The sieve mesh is located at the bottom of the sieve cylinder. The upper part of the sieve cylinder is a flanged pipe matching the lower diameter of the square-round pipe joint. The quick clamp is provided with a sealing groove. The quick clamp fixedly connects the square-round pipe joint and the sieve cylinder through the sealing groove. The micro vibration motor is fixedly connected to the sieve mesh.

[0005] Further, the bottom of the sieve cylinder is provided with an annular groove, the sieve mesh is located in the annular groove, and a gap for vibrating the sieve mesh up and down is provided in the annular groove.

[0006] Further, a rubber pad is provided on the flange.

[0007] Further, a plurality of impact balls are provided on the sieve mesh.

[0008] Further, the sieve mesh is a standard sieve of 10 mesh stainless steel material.

[0009] The utility model has the following advantages: Through the square-to-round pipe joint installed at the outlet of the discharge hopper of the ball mill, the stainless steel screen, and the micro vibration motor fixed thereon for auxiliary screening, it can automatically screen out the fine steel balls or other impurities with a size larger than 2 mm mixed in the micro powder abrasive while the ball mill is discharging, avoiding the problems of low efficiency, dust pollution, and material waste in the traditional manual screening method; there is no need to frequently disassemble and remove the steel balls because a small amount of steel balls can assist the screening effect; the setting of the stainless steel quick clamp enables the stainless steel screen to be quickly taken out and cleaned, which is convenient, fast, and easy to operate.
