Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tea production process equipment, in particular to an iron removal device of a mesh belt type tea drying machine. Background Art
[0002] In the tea production process, the first thing to do is to make the fresh tea leaves into primary processed tea. After the fresh tea leaves are processed into green tea, black tea and oolong tea through different primary processing techniques, they must also be dried through a drying process to control the moisture content in them within a reasonable range to facilitate the preservation of the primary processed tea.
[0003] The traditional tea processing does not include iron removal. However, in order to catch up with the picking season, improve tea picking efficiency, reduce costs and the labor intensity of tea farmers, fresh tea leaves are increasingly picked by machine. During the picking and transportation process, iron parts such as screws and nuts may fall into the picked fresh tea leaves. If the primary tea does not go through the iron removal process, the iron parts mixed in the tea during the machine picking process and the subsequent transportation process may be packaged together in the primary tea bag. Since the dried primary tea still contains a certain amount of moisture (generally about 6%), these iron parts will react with the moisture in the tea and the oxygen in the tea bag to produce rust, which will pollute the tea and affect the safety of drinking tea. Therefore, we propose a deironing device for a mesh belt tea dryer to solve the above problem. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model provides an iron removal device for a mesh-belt type tea drying machine, which is used to solve the above problems.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A deironing device for a mesh-belt tea dryer comprises a mesh-belt tea dryer body, a conveying device is arranged on the mesh-belt tea dryer body, a plurality of mounting frames are fixedly mounted on one side of the mesh-belt tea dryer body, a same discharging device is fixedly mounted on the plurality of mounting frames, the discharging device is composed of a feed hopper, a spiral conveying pipe and a discharging box, a magnet is fitted on the spiral conveying pipe, and elastic lifting mechanisms for the magnets are arranged on the two corresponding mounting frames.
[0007] Preferably, the feed hopper is located directly below the discharge end of the conveying device, and the feed hopper is arranged in a frustum structure.
[0008] Preferably, the magnet is arranged in a semicircular spiral structure, and the magnet is adapted to the spiral conveying tube. When the magnet is attached to the spiral conveying tube, the iron pieces in the primary tea will be adsorbed by the magnet on the top wall of the spiral conveying tube.
[0009] Preferably, the elastic lifting mechanism includes a cylinder, an inner chamber, a circular plate, a spring and a connecting rod, the cylinder is fixedly mounted on the bottom side of the mounting frame, an inner chamber is opened in the cylinder, a circular plate is movably mounted in the inner chamber, one end of the spring is fixedly mounted on one side of the circular plate, the other end of the spring is fixedly mounted on the top inner wall of the inner chamber, one end of the connecting rod is fixedly mounted on the other side of the circular plate, the other end of the connecting rod is movably penetrated to the outside of the cylinder and is fixedly connected to the magnet, and the two elastic lifting mechanisms are used to facilitate the up and down adjustment of the magnet.
[0010] Preferably, the spring and the connecting rod are located above and below the circular plate respectively, and the cross-sectional dimension of the spring is smaller than the cross-sectional dimension of the inner chamber.
[0011] Preferably, a collecting box is placed on one side of the mesh-belt tea drying machine body, and the collecting box is located just below the discharge end of the discharge box, and the primary processed tea after the iron pieces are removed is collected through the collecting box.
[0012] The beneficial effect of the utility model is that the iron removal device of the mesh-belt tea dryer can adsorb the iron pieces in the primary processed tea to the top wall of the spiral conveying tube by the magnet attached to the spiral conveying tube. When the iron pieces adsorbed on the inner wall of the spiral conveying tube need to be removed, the two elastic lifting mechanisms can be used to adjust the magnet to be separated from the spiral conveying tube, so that the adsorbed iron pieces can slide out through the spiral conveying tube and the discharge box. The operation is very simple. The method in this case is convenient for removing iron pieces in the primary processed tea, avoids the contamination of tea leaves, and ensures the safety of tea drinking.

[0019] Furthermore, the feed hopper 5 is located directly below the discharge end of the conveying device 2, and the feed hopper 5 is arranged in a truncated cone structure.
[0020] Furthermore, the magnet 8 is arranged in a semicircular spiral structure, and the magnet 8 is adapted to the spiral conveying tube 6. When the magnet 8 is attached to the spiral conveying tube 6, the iron pieces in the primary tea will be adsorbed by the magnet 8 on the top wall of the spiral conveying tube 6.
[0021] Furthermore, the spring 12 and the connecting rod 13 are respectively located above and below the circular plate 11 , and the cross-sectional dimension of the spring 12 is smaller than the cross-sectional dimension of the inner chamber 10 .
[0022] Furthermore, a collecting box 14 is placed on one side of the mesh-belt tea drying machine body 1. The collecting box 14 is located just below the discharge end of the discharge box 7. The primary processed tea after the iron pieces are removed is collected through the collecting box 14.
[0023] During use: the dried primary tea is conveyed to the feed hopper 5 through the conveying device 2 on the mesh-belt tea dryer body 1, and then enters the spiral conveying tube 6. The iron pieces in the primary tea will be adsorbed by the magnet 8 on the top wall of the spiral conveying tube 6. Then, the primary tea with the iron pieces removed falls into the collecting box 14 through the discharging box 7. The collecting box 14 collects the primary tea with the iron pieces removed; when it is necessary to remove the iron pieces adsorbed on the inner wall of the spiral conveying tube 6, the magnet 8 is adjusted to move upward to separate from the spiral conveying tube 6. At this time, the two circular plates 11 on the two connecting rods 13 slide upward in the corresponding inner chambers 10 respectively. At this time, the two springs 12 are subjected to force to produce deformation and compression. When the magnet 8 separates from the spiral conveying tube 6, the adsorbed iron pieces slide out through the spiral conveying tube 6 and the discharging box 7.
