Description

Technical Field

[0001] This utility model relates to the technical field of tea production equipment, specifically a tea dust separation device for tea processing. Background Technology

[0002] During processing, storage, and transportation, tea leaves become fragile and easily broken due to moisture evaporation. These broken tea leaves can mix with whole tea leaves, affecting their quality. Therefore, it is necessary to separate these tea leaves from the tea leaves. The existing method for removing tea leaves is mainly manual. People hold a winnowing basket or tray and toss the roasted tea leaves in the basket or tray to separate the tea leaves from the tea leaves. This manual sorting method is inefficient.

[0003] The existing publication number CN219210627U discloses a tea and tea dust separation device, including a box body with a feed inlet, a filter plate inside the box body, a vibrating screen inside the box body, and a vibrating device on the box body to drive the vibrating screen. Tea leaves are put into the box body through the feed inlet, and the filter plate performs a first filtration. The filtered tea leaves fall onto the vibrating screen, while the filtered tea dust falls into the box body. The vibrating device drives the vibrating screen to vibrate, performing a second filtration of the tea leaves. The filtered tea leaves are carried out of the box body through the discharge outlet, while the tea dust falls into the box body and is conveyed out of the box body by a conveying device. No manual filtration of the tea leaves is required.

[0004] Existing technology filters tea leaves by vibration, but this process can easily damage the whole tea leaves again. In addition, the existing technology uses a planar conveying method, which makes it difficult for the tea leaves to tumble. This causes the tea leaves to get stuck and not easily shaken off, resulting in incomplete removal of the leaves. Utility Model Content

[0005] The purpose of this invention is to provide a tea dust separation device for tea processing, which solves the problem that the existing technology filters tea dust by vibration, but the vibration process can easily damage the whole tea leaves again. In addition, the existing technology uses a planar conveying method, which makes it difficult for the tea leaves to tumble, causing the tea dust to be stuck and not easily shaken off, resulting in incomplete removal of the tea dust.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a tea dust separation device for tea processing, comprising a processing body and a rotating motor disposed above the processing body, a conveying roller connected to the rotating motor being disposed inside the processing body, a plurality of inwardly recessed material grooves being provided on the circumferential surface of the conveying roller, ventilation holes being provided in the material grooves, a collection cover being disposed above the conveying roller, the collection cover being connected to an air pump, a dust removal fan being disposed inside the conveying roller, the dust removal fan facing the circumferential surface of the conveying roller, a belt feeder being connected to one side of the processing body, and a belt discharger being connected to the other side, the belt feeder being located above the conveying roller, and the belt discharger being located below the conveying roller.

[0007] Furthermore, the collection cover covers the portion above the transverse axial surface of the conveying roller.

[0008] Furthermore, the top of the terminal fan is provided with an air diffuser, which faces the circumference of the conveying roller.

[0009] Furthermore, the conveying roller has a connecting plate on one side and an opening on the other side. The processing machine body has a support frame inside, which extends into the conveying roller through the opening and has a gap with the inner circumferential surface of the conveying roller to support the desiccant fan.

[0010] Furthermore, the output end of the rotary motor is connected to the connecting plate.

[0011] Furthermore, the upper end of the belt feeder is located above the transverse axial surface of the conveying roller and close to the circumferential surface of the conveying roller.

[0012] Furthermore, a support base is provided at the bottom of the processing machine body.

[0013] Furthermore, a safety door is hinged to one side of the processing machine body.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] The rotating motor drives the conveyor roller to rotate, and the tea leaves are transported to the material trough by the belt feeder. As the tea leaves and leaf dust are transported on the conveyor roller, the dust removal fan inside the conveyor roller blows the leaf dust in the material trough and carries it out of the processing machine through the collection cover and the air pump. The material trough is opened on the circumference of the conveyor roller, and the arc surface of the conveyor roller is used as the conveyor line. In the limited space of the processing machine, the dust removal time of the tea leaves through the arc conveyor line is longer than that of the straight conveyor line, which makes reasonable use of space and removes leaf dust for a longer and cleaner time. At the same time, the inwardly recessed material trough on the circumference of the conveyor roller allows the tea leaves carried by the belt feeder to fall onto the circumference of the conveyor roller, and the tea leaves will not slip off the circumference of the conveyor roller, realizing the combination of the conveyor roller and the belt feeder.

[0016] This invention solves the problem of damage to tea leaves caused by vibration in existing technologies for removing tea leaves. By installing a leaf removal fan in the conveying roller, and a collection cover and air pump above it, the tea leaves are transported by the rotation of the conveying roller, and the leaf removal fan removes leaf dust. The air pump, in conjunction with the leaf removal fan, carries the leaf dust blown out of the tea leaves out of the processing machine. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0025] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0026] like Figures 1 to 5 As shown, this utility model provides a tea dust separation device for tea processing, including a processing body 1, which is made of rectangular sheet metal. One side of the processing body 1 is closed and the other side is open. A rotating motor 2 is located above the processing body 1, installed on the closed side of the processing body 1 and in the middle of the processing body 1. A conveying roller 3 connected to the rotating motor 2 is provided inside the processing body 1. The circumference of the conveying roller 3 has multiple inwardly recessed material grooves 31, which are circular. The material grooves 31 have ventilation holes 32 inside. A collection cover 4 is provided above the conveying roller 3, which is connected to a vacuum pump 41. A dust removal fan 5 is provided inside the conveying roller 3, facing the circumference of the conveying roller 3. A belt feeder 6 is also connected to one side of the processing body 1, and a belt discharger 7 is connected to the other side. The belt feeder 6 is located above the conveying roller 3, and the belt discharger 7 is located below the conveying roller 3.

[0027] The rotating motor 2 drives the conveyor roller 3 to rotate, and the tea leaves are conveyed to the material trough 31 by the belt feeder 6. When the tea leaves and leaf dust are conveyed on the conveyor roller 3, the leaf dust removal fan 5 inside the conveyor roller 3 blows the leaf dust in the material trough 31 and carries it out of the processing machine body 1 through the collection cover 4 and the air pump 41. The material trough 31 is opened on the circumference of the conveyor roller 3, and the arc surface of the conveyor roller 3 is used as the conveyor line. In the limited space inside the processing machine body 1, the leaf dust removal time of the tea leaves through the arc conveyor line is longer than that of the straight conveyor line. This makes reasonable use of space and the leaf dust removal time is longer and cleaner. Meanwhile, this utility model has an inwardly recessed material trough 31 on the circumference of the conveyor roller 3, which allows the tea leaves carried by the belt feeder 6 to fall onto the circumference of the conveyor roller 3 without slipping off. This achieves the integration of the conveyor roller 3 and the belt feeder 6. When the tea leaves are conveyed with the conveyor roller 3, the circular material trough 31 will have different tilt angles, and the tea leaves will tumble in the material trough 31. This solves the problem that the tea leaves will not tumble during the conveying process of the parallel conveyor belt, which would cause the tea leaves to be pressed down and the dust removal fan 5 to be unable to blow away the pressed tea leaves, resulting in incomplete cleaning.

[0028] This invention solves the problem of damage to tea leaves caused by vibration in the prior art of removing tea leaves by setting a leaf removal fan 5 in the conveying roller 3, and setting a collection cover 4 and an air pump 41 above it. The rotation of the conveying roller 3 drives the tea leaves to be transported, and the leaf removal fan 5 removes leaf dust. The air pump 41, in conjunction with the leaf removal fan 5, carries the leaf dust blown out of the tea leaves out of the processing machine body 1.

[0029] like Figure 1 and Figure 2 As shown, the collection cover 4 covers the part above the transverse axis of the conveying roller 3, that is, the collection cover 4 just covers the air outlet of the dust removal fan 5. Similarly, the tea leaves are conveyed in the upper part of the conveying roller 3. The collection cover 4 makes the air force of the dust removal fan 5 more concentrated, which can better remove the tea dust in the tea leaves.

[0030] The top of the de-fan 5 is provided with an air diffuser 51, which faces the circumferential surface of the conveying roller 3. The air diffuser 51 can effectively increase the area of ​​the air outlet. When the de-fan 5 is running, the air blown out from the fan blades is diffused to the circumferential surface of the conveying roller 3 through the air diffuser 51. Compared with the case without the air diffuser 51, the air diffuser 51 allows the blown air to cover a wider area.

[0031] like Figure 1 , 3 and Figure 4As shown, the conveyor roller 3 has a connecting plate 33 on one side and an opening on the other side. The processing machine body 1 has a support frame 35 inside. The support frame 35 extends into the conveyor roller 3 through the opening and has a gap with the inner circumferential surface of the conveyor roller 3 to support the de-icing fan 5. The conveyor roller 3 is closed on one side by the connecting plate 33 and has an open opening on the other side. The connecting plate 33 is used to connect with the rotating motor 2 so that the rotating motor 2 can drive the conveyor roller 3 to rotate. The open side facilitates the installation of the de-icing fan 5. The de-icing fan 5 is fixed in the conveyor roller 3 by the support frame 35. The support frame 35 consists of two rectangular plates placed horizontally inside the conveyor roller 3. The two de-icing fans 5 are vertically installed on the two support frames 35. The periphery of the support frame 35 is not connected to the conveyor roller 3. The support frame 35 is suspended in the conveyor roller 3. The support frame 35 is fixed by two extended support rods. The two support rods are installed on the processing machine body 1 by bolts.

[0032] like Figure 2 and Figure 5 As shown, the upper end of the belt feeder 6 is located above the transverse axial surface of the conveying roller 3 and close to the circumferential surface of the conveying roller 3. The belt feeder 6 is used to transfer unprocessed tea leaves into the processing machine body 1. The end of the belt feeder 6 that extends into the processing machine body 1 must be higher than the upper part of the transverse circumferential surface of the conveying roller. When the conveying roller rotates, the material trough 31 located above the transverse circumferential surface is tilted upwards, so that when the tea leaves pushed out from the belt feeder 6 enter the material trough 31, they will not fall out of the material trough 31.

[0033] The bottom of the processing machine body 1 is equipped with a support base 8. Located at the bottom of the processing machine body 1, the support base 8 primarily provides stable support for the entire tea dust separation device. It bears the weight of the processing machine body 1 and all internal components, ensuring the entire device can be placed stably on the ground or operating platform. A safety door 9 is hinged to one side of the processing machine body 1. During tea processing, there may be some moving parts inside the device (such as separation rollers, transmission devices, etc.). It is dangerous for personnel to touch these parts while the device is running. The safety door 9 acts as a protective barrier. When properly closed, it prevents operators from accidentally touching dangerous moving parts inside, avoiding accidents. Simultaneously, it also prevents external dust and debris from entering the processing machine body 1, ensuring a relatively clean environment for tea dust separation and improving the quality and efficiency of tea dust separation.

[0034] This utility model provides a tea dust separation device for tea processing. It features a conveyor roller 3 with a circular material trough 31, driven by a rotating motor 2. The curved surface of the conveyor roller 3 serves as the conveyor line, extending the tea dust removal time. The material trough 31 is designed to prevent tea leaves from slipping and to agitate them, solving the problem of incomplete dust removal caused by tea leaves not agitating on parallel conveyor belts. A dust removal fan 5 is installed inside the conveyor roller 3, with a collection hood 4 and an air pump 41 above it, preventing damage to the tea leaves from vibration-induced dust removal. The collection hood 4 concentrates airflow to improve the dust removal effect, and the air diffuser hood 51 increases the air outlet area. The dust removal fan 5 is installed and supported by a connecting plate 33, an opening, and a support frame 35. The specific positioning design of the belt feeder 6 ensures that the tea leaves accurately fall into the material trough 31, improving the efficiency and quality of tea dust separation. This device demonstrates excellent practicality and innovation.

[0035] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
