Description

Technical Field

[0001] The utility model relates to tea processing equipment, in particular to an iron removal device before tea extraction. Background Art

[0002] Tea extraction requires a large amount of fresh tea leaves. In order to improve tea picking efficiency and reduce costs, fresh tea leaves are often picked by machines, and tea is increasingly processed by machines. Therefore, during the process of tea picking, tea making and transportation, iron parts such as screws, wires and springs may fall into the tea leaves. If these iron parts are not removed, they may be packaged in. These iron parts will scratch or damage the extraction equipment, and the presence of these iron parts will also affect the sensory quality and drinking safety of the finished tea. Therefore, further removing the iron parts mixed in the tea leaves before extraction is conducive to avoiding equipment losses and product quality problems caused by iron parts.

[0003] The existing iron removal device for tea leaves generally simply allows the tea leaves to pass through the permanent magnet for adsorption, which results in uneven iron removal and makes it difficult to clean the finer iron filings adsorbed on the permanent magnet, which can easily affect the subsequent iron removal effect. The iron removal device combined with the vibrating screen will also cause the light tea leaves to move in the opposite direction of the discharge port when the number of tea leaves is large, and manual intervention is required, which greatly reduces the work efficiency. Therefore, the improvement of the vibration device has become a very important topic. Summary of the invention

[0004] The purpose of the utility model is to provide an iron removal device before tea extraction in view of the defects existing in the prior art. The utility model comprises a base 1, a vibrating device 2, a feeding device 3 and a discharging device 4, wherein the vibrating device 2 is fixed on the base 1, a base 9 is provided in the vibrating device 2 and connected to the base 1 through a spring 10, a vertical direction vibrator 11, a horizontal direction vibrator 12 and a front-to-back direction vibrator 13 are respectively installed on the base 9, and the vertical direction vibrator 11, the horizontal direction vibrator 12 and the front-to-back direction vibrator 13 are respectively connected to a pneumatic generator 14 through pipelines, a feeding device 3 is provided on the upper part of the vibrating device 2, a discharging device 4 is provided at the end of the feeding device 3, a discharging port 5 is provided at the tail end of the discharging port 4, a magnet array 7 is provided on the discharging port wall 6 of the discharging port 5, and a protruding ring 8 is provided at the discharging port of the discharging device 4.

[0005] The vibration amplitudes of the vibration device 2 in the vertical direction, horizontal direction and front-to-back direction are adjusted by the vertical direction vibrator 11, the horizontal direction vibrator 12 and the front-to-back direction vibrator 13. Thus, the amplitudes in the vertical direction, horizontal direction and front-to-back direction are changed.

[0006] The electromagnet on the discharge port wall 6 is a magnet array 7, which is a replaceable electromagnet sheet and is equipped with magnet array replacement parts of different densities, so as to fully remove iron pieces in tea leaves of different mesh sizes while ensuring work efficiency.

[0007] The magnet array 7 loses its magnetism after power is turned off, causing the iron parts adsorbed thereon to fall off, making it easier to clean.

[0008] The utility model has the advantages of fully removing iron from tea leaves of different mesh sizes through the vibration device and the electromagnet arrays of different densities, greatly improving the work efficiency; at the same time, the cloth bag at the discharge port can fully collect the tea leaves after iron removal and reduce environmental pollution; the magnetism of the electromagnet disappears after power is cut off, the adsorbed iron parts fall off, and the electromagnet array is detachable for easy cleaning.
