Description

Technical Field

[0001] This utility model relates to the field of barley flour processing technology, and in particular to a filter for barley grinding. Background Technology

[0002] During the processing of barley flour, iron grinding devices are inevitably used. These devices inevitably produce iron filings and other iron-containing substances in the barley flour. The presence of iron filings affects the quality of the barley flour. Therefore, an adsorption magnet is usually installed in the conveying pipeline to adsorb the iron-containing substances. However, due to the limited adsorption capacity of the magnet, and the fact that the barley flour forms a powder flow that aggregates when it is discharged, it is not easy to adsorb the iron filings and iron-containing substances within it, resulting in poor removal of iron filings and iron-containing substances. Utility Model Content

[0003] This utility model provides a filter for grinding highland barley to overcome the shortcomings of the prior art and solve the problem of poor removal effect of iron-containing substances and iron filings, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted: A filter for grinding highland barley includes a feed pipe, a first ring at the lower end of the feed pipe, a second ring below the first ring, a filter tube welded to the inner circumference of the second ring, a third ring welded to the lower end of the filter tube, a fourth ring below the third ring, a discharge pipe welded to the inner circumference of the fourth ring, multiple fixing screws passing through the first, second, third, and fourth rings, and fixing nuts connected to the two ends of the fixing screws by threads to fix the first, second, third, and fourth rings, and multiple magnetic rods welded to the inner circumference of the filter tube.

[0005] Furthermore, the magnetic rod includes an inclined upper rod, which is welded to the inner circumference of the filter tube. The inner end of the upper rod extends downward at an incline. A vertical rod is formed at the lower end of the upper rod, and a horizontal rod is formed at the lower end of the vertical rod by bending inward. The horizontal rod is welded to the inner circumference of the filter tube.

[0006] Furthermore, a fifth ring is provided between the first ring and the second ring. A lower extension ring is welded to the inner circumference of the fifth ring, and a conical bucket is welded to the lower end of the lower extension ring. The lower end of the conical bucket is open, and the open end is the small end.

[0007] Furthermore, a lower plate is provided between the third and fourth rings. The lower plate has multiple holes and a lower end plate is fixed to it by bolts. A mounting ring is fixed to the lower end plate by bolts. An inner tube is welded to the outer circumference of the mounting ring. There is an annular gap between the inner tube and the inner wall of the filter tube. The magnetic rod is located in the annular gap. A fixing ring with an L-shaped longitudinal section is welded to the upper end of the inner tube. An upper end plate is fixed to the fixing ring by bolts. A rotating shaft is rotatably provided on the upper end plate. A pair of bearings are provided on the rotating shaft. The bearing at the upper end is fixed to the upper end plate, and the bearing at the lower end is fixed to the lower end plate. A conical head is provided at the upper end of the rotating shaft. The upper part of the outer circumference of the conical head has a conical structure, and multiple spiral blades are welded to the outer circumference of the conical head.

[0008] Furthermore, the inner wall of the inner tube is fixed to the fixed base, and a motor is fixed on the fixed base. The output shaft of the motor is connected to a drive gear, which meshes with a driven gear. The driven gear is fixed to the lower end of the rotating shaft. Holes are opened on the inner tube and the filter tube. The power supply line of the motor passes through the hole and is covered with a protective tube.

[0009] The advantages of the above technical solution are: In this invention, when adsorbing iron filings, the barley flour is first collected through a conical hopper. The collected barley flour impacts the conical head, and its conical structure breaks up the flour. The broken barley flour is then discharged outwards. During the discharge process, the barley flour passes through the annular gap between the inner tube and the filter tube, and the magnetic rod adsorbs the iron-containing substances or iron filings in the barley flour. This adsorption method can improve the adsorption capacity of iron-containing substances.

[0010] Alternatively, a motor can be used to drive the conical head to rotate, and during the rotation, the barley flour can be broken up and thrown out through the spiral blades on it, which can further enhance the adsorption capacity and effect of iron-containing substances in the flour.
