Abstract

The utility model relates to an iron removal device used in a refining of Keemun black tea. The device comprises magnets which are arranged above a tea conveyer belt, wherein two ends of the magnets are respectively fixed on fixed parts on both sides of the conveyor belt, a distance between the lower surface of the magnets and the tea conveyer belt satisfies requirements of the magnets for absorbing iron filings on the tea conveyer belt. The device uses a multilayer screen surface to screen the tea, is high in screening efficiency, greatly reduces labor intensity of workers, and substantially increases impurity removing rate at the same time. The screened tea is uniform in thickness. By arranging the magnets and using the magnets to absorb the iron filings in the tea, the iron filings in the tea can be removed conveniently, and quality of the tea can be improved.

Description

The equipment for removing ferric ion that uses in a kind of Keemun black tea subtractive process

Technical field

The utility model relates to a kind of equipment for removing ferric ion, relates in particular to the equipment for removing ferric ion that uses in a kind of Keemun black tea subtractive process.

Background technology

Tealeaves fine finishining is a very numerous and diverse job, each tealeaves monomer generally will be through the quality of tens roads even more operation guarantee final finished, each procedure all will carry out complicated processing in process equipment, and tea-processing equipment basically all ferrous materials make, so having a large amount of iron filings in the Tea Processing process is mingled in the tealeaves, iron filings can badly influence the quality of tealeaves, greatly reduce the grade of tealeaves, therefore must remove the iron filings that exist in the tealeaves, particularly when producing high-grade tealeaves, even considerably less iron filings, not unallowed, by screening the iron filings in the tealeaves are removed, but this kind method de-ironing efficiency is lower, working strength is larger, and the method de-ferrous effect is also undesirable in addition.

The utility model content

The purpose of this utility model is to provide a kind of equipment for removing ferric ion of using in the Keemun black tea subtractive process of de-ferrous effect of guaranteeing.

The purpose of this utility model is achieved through the following technical solutions; The equipment for removing ferric ion that uses in a kind of Keemun black tea subtractive process, comprise magnet, magnet is arranged at tealeaves conveyer belt top, the two ends of magnet are separately fixed on the fixture on both sides of conveyer belt, and the distance of the lower surface of magnet and tealeaves conveyer belt satisfies magnet can be with the requirement of the iron adsorption on the tealeaves conveyer belt.

Further, described magnet is that some the bar shaped permanent magnetic irons that are parallel to each other or electromagnet form.

Further, described magnet is a tabular whole permanent magnetic iron.

Further, described magnet is arranged on the end of conveyer belt.

Further, the lower surface of described magnet is 3-6cm apart from the distance of tealeaves conveyer belt.

The advantage of the equipment for removing ferric ion that uses in the Keemun black tea subtractive process that the utility model provides is: by magnet is set, utilize the iron filings in the magnet sucking-off tealeaves, can remove very easily the iron filings in the tealeaves, guarantee the Iron in Tea bits, promote the quality of tealeaves.

Description of drawings

Fig. 1 is the structural representation of the equipment for removing ferric ion that uses in the utility model Keemun black tea subtractive process.

Fig. 2 is that the utility model is assemblied in the overall structure schematic diagram on the production line.

The specific embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.

See also Fig. 1 and Fig. 2, wherein Fig. 1 is the structural representation of the equipment for removing ferric ion that uses in the utility model Keemun black tea subtractive process, and Fig. 2 is that the utility model is assemblied in the overall structure schematic diagram on the production line.

As shown in Figure 1, the equipment for removing ferric ion that uses in a kind of Keemun black tea subtractive process of the utility model embodiment comprises magnet 64, described magnet 64 is a tabular whole permanent magnetic iron, described magnet 64 is arranged on the end of conveyer belt 61, magnet 64 is arranged at tealeaves conveyer belt 61 tops, the two ends of magnet 64 are separately fixed on the fixture on both sides of conveyer belt 61, the lower surface of described magnet 64 is 3-6cm apart from the distance of tealeaves conveyer belt 61, the distance of the lower surface of described magnet 64 and tealeaves conveyer belt 61 also can be according to magnet 64 magnetic force size, the actual conditions such as tealeaves paving thickness are adjusted, can be with the requirement of the iron adsorption on the tealeaves conveyer belt 61 but must satisfy magnet 64.It is not very important that the utility model is selected the magnet of which kind, as long as have the magnetic force that satisfies condition, can select native magnet, also can select artificial magnet, but the permanent magnetic iron that recommendations for selection is artificial, in addition, described magnet can also select some the bar shaped permanent magnetic irons that are parallel to each other or electromagnet to form except selecting above-mentioned tabular whole permanent magnetic iron.

As shown in Figure 1, tealeaves moves with conveyer belt 61 on conveyer belt 61, when tealeaves moves to magnet 64 below, because magnet 64 has magnetic force, magnet 64 with the iron adsorption that mixes in the tealeaves on magnet 61, namely finish the iron removal of tealeaves, tealeaves continues to move to the conveyer belt end with conveyer belt 61 and falls in the hopper 62 of conveyer belt end, by the discharge nozzle 63 that connects on the hopper 62 tealeaves is exported again.

Fig. 2 is that the utility model is assemblied in the overall structure schematic diagram on the production line, this production line comprises drying plant 1, even heaping equipment 5, equipment for removing ferric ion 6, screening plant 8 and weighing-appliance 7, be connected by transfer tube 2 or transport tape 3 between equipment and the equipment, in process of production, tealeaves is dried by drying plant 1 first, by transfer tube 2 it is transferred on the transport tape 3 after the oven dry, transport tape 3 is delivered to pan feeding hole interior 4 with tea leaf conveying, by transfer tube 2 it is transferred in the even heaping equipment 5 again, through being transported on the equipment for removing ferric ion 6 by transport tape 3 again after the even heaping equipment 5 even heaps, through after the deironing, tea leaf is crossed transfer tube 2 and is transferred on the screening plant 8 and sieves, rear being transferred on the weighing-appliance 7 by transfer tube 2 of screening weighed, and packs afterwards warehouse-in.

The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
