Abstract
Description
Technical Field
[0001] This utility model relates to the field of tea processing technology, and in particular to a tea air separator with good screening effect. Background Technology
[0002] The tea-making process includes picking, sifting, fixing, rolling, and drying. After fixing, the tea leaves need to be sorted to separate the tea leaves, yellow leaves, and broken tea.
[0003] In the existing technology, when sorting tea leaves by air, a blower is usually used for screening. The tea leaves are transported to the air sorting equipment by a feeding conveyor, and the tea leaves fall due to gravity. Then, the air blown by the blower sorts the tea leaves.
[0004] However, after processing, the tea leaves contain a certain amount of moisture and are relatively long and thin. Therefore, when the tea leaves are poured into the feeding hopper and conveyed to the equipment for air separation, they will clump together. This causes the tea leaves to clump together during feeding. Because of their greater weight, the clumps of tea leaves may fall directly without air separation or be blown a greater distance by the fan due to their larger surface area. This results in the tea leaves being mixed in shape, thus affecting the screening effect. Therefore, a tea air separator with good screening effect is proposed to solve the above problems. Utility Model Content

[0029] like Figure 1-4 As shown, the present invention proposes a tea air separator with good screening effect, including a base plate 1, a base 2 fixedly connected to the base plate 1, a screening cylinder 3 provided on the base 2, and air separators 4 for tea air separation provided on the screening cylinder 3 and the base plate 1.
[0030] The base 2 is equipped with a drive component 5 for driving the conical cylinder 410 to rotate.
[0031] In this invention, the air separator 4 located on the screening cylinder 3 can agitate and disperse the tea leaves when they are added. The dispersed tea leaves enter the screening cylinder 3 and rotate with it, which can make the tea leaf screening more thorough and thus improve the tea leaf screening effect.
[0032] In an optional embodiment, the air separator 4 includes a support frame 41 fixedly connected to one side of the base plate 1. A drive motor 42 is fixedly installed on the outer side of the support frame 41. A connecting pipe 44 with one end penetrating and extending to the inner side of the screening cylinder 3 is fixedly connected to the upper end of the support frame 41. A fan 43 is fixedly installed on the inner wall of the upper end of the connecting pipe 44. A feeding hopper 45 is connected to the connecting pipe 44. The output shaft of the drive motor 42 is fixedly connected to a rotating shaft 411 with one end penetrating and extending to the inner side of the connecting pipe 44. A plurality of stirring rods 46 are fixedly connected to the outer side of the rotating shaft 411. A plurality of guide strips 47 are fixedly connected to the inner wall of the screening cylinder 3. A support block 48 is fixedly connected to the outer side of the screening cylinder 3. A conical cylinder 410 is hinged to the end of the screening cylinder 3 away from the support frame 41. An electric push rod 49 with one end hinged to the conical cylinder 410 is hinged to the support block 48. A filter bag 7 is sleeved on one end of the conical cylinder 410.
[0033] In this embodiment, when the tea leaves to be air-sorted are fed into the screening cylinder 3 through the feeding hopper 45, the tea leaves can be stirred and dispersed by the rotating stirring rod 46 to reduce the possibility of the tea leaves easily forming clumps during the feeding process. After the dispersed tea leaves are introduced into the screening cylinder 3 through the connecting pipe 44, they can be continuously turned over by the guide strip 47 inside the screening cylinder 3, so that the tea leaves turned to the top can be blown and screened more thoroughly by the fan 43 during the falling process, thereby improving the tea leaf screening effect.
[0034] It should be noted that several guide strips 47 are distributed in a ring at equal intervals on the inner wall of the screening cylinder 3. The tea leaves introduced into the screening cylinder 3 are driven by the several ring-shaped guide strips 47 to rotate with the screening cylinder 3. The tea leaves that rotate to the top can be blown by the fan 43 during the falling process, and the air separation is continuous. One end of the connecting pipe 44 passes through the screening cylinder 3 and is rotatably connected to the inner wall of the screening cylinder 3 through a sealed bearing, which increases the sealing of the connection between the connecting pipe 44 and the screening cylinder 3.
[0035] The screening cylinder 3 is inclined on the base 2, so that the screening cylinder 3 can guide the tea leaves from right to left and also drive the tea leaves to rotate and turn. A valve is set in the middle of the feeding hopper 45, and the opening and closing of the feeding hopper 45 is controlled by the valve.
[0036] In an optional embodiment, the base 2 is provided with a driving component 5 for driving the conical cylinder 410 to rotate; the driving component 5 includes a support ring 51 fixedly connected to the base 2 and located outside the screening cylinder 3, the base 2 is provided with a mounting groove 53, a dual-axis motor 54 is fixedly installed inside the mounting groove 53, gears 55 are fixedly connected to the output shafts on both the left and right sides of the dual-axis motor 54, and a rack 52 with one end meshing with the gear 55 is fixedly connected to the outside of the screening cylinder 3.
[0037] In this embodiment, the dual-axis motor 54, once started, can drive the screening cylinder 3 to rotate stably on the support ring 51 through the cooperation of the gear 55 and rack 52 at its output shaft.
[0038] It should be noted that a slider with one end extending into the screening cylinder 3 is fixedly connected to the inner side of the support ring 51. An annular groove is provided on the outer side of the screening cylinder 3, and the annular groove is slidably connected to the slider. The stability of the support ring 51 supporting the screening cylinder 3 is improved by the cooperation between the slider inside the support ring 51 and the groove on the screening cylinder 3.
[0039] In an optional embodiment, the mounting component 6 includes two mounting blocks 61 sleeved on the outer side of the end of the conical cylinder 410. The upper and lower ends of the mounting blocks 61 are provided with mounting bolts 62. The inner side of the mounting blocks 61 is fixedly connected with a stop block 63. One end of the conical cylinder 410 is provided with the mounting component 6 for supporting and fixing the filter bag 7.
[0040] In this embodiment, by tightening the mounting bolts 62 at the upper and lower ends of the two mounting blocks 61, the abutment 63 inside the mounting block 61 extends into the conical cylinder 410 to abut and fix the filter bag 7 fitted on the conical cylinder 410. Alternatively, by loosening the mounting bolts 62, the filter bag 7 can be removed to centrally process the filtered impurities and substandard tea leaves.
[0041] It should be noted that the outer side of the tapered cylinder 410 away from the screening cylinder 3 has a groove that matches the abutment block 63, so that the abutment block 63 extending into the groove squeezes the sleeve of the filter bag 7 into a concave shape, thereby improving the stability of the sleeve between the filter bag 7 and the tapered cylinder 410. The mounting block 61 is semi-circular, and the upper and lower ends of the mounting block 61 are L-shaped. The mounting bolt 62 is set on the L end of the mounting block 61.
[0042] All electrical components mentioned in the article are electrically connected to the main controller and power supply. The main controller can be a conventional known device such as a computer that performs control functions, and existing publicly available power connection technologies are not described in detail in the article.
[0043] The working principle in the above embodiments is as follows:
[0044] When the valve on the feeding hopper 45 is opened and the tea leaves to be air-separated are fed into the screening cylinder 3 through the feeding hopper 45, the drive motor 42 can be started to drive the rotating shaft 411 to rotate, so that the stirring rod 46 driven by the rotating shaft 411 can stir and disperse the tea leaves, thereby reducing the possibility of the tea leaves easily forming clumps during the feeding process, and making the tea leaves introduced into the screening cylinder 3 through the connecting pipe 44 more loose. After the dispersed tea leaves are introduced into the screening cylinder 3 through the connecting pipe 44;
[0045] The valve on the feeding hopper 45 can be closed, and then the blower 43 and the dual-shaft motor 54 can be turned on. The started dual-shaft motor 54 can drive the screening cylinder 3 to rotate stably on the support ring 51 through the cooperation of the gear 55 and rack 52 at its output shaft. This allows the guide strip 47 inside the screening cylinder 3 to be continuously turned. The tea leaves turned to the top can be blown by the blower 43 to screen more thoroughly during the falling process. The unqualified tea leaves and impurities are blown into the filter bag 7 for blocking and filtration. After the air screening is completed, the cone cylinder 410 is driven to rotate and open by the started electric push rod 49, and the air-screened tea leaves can be exported.
[0046] By rotating the mounting bolts 62 on the mounting block 61, operators can easily fix or remove the filter bag 7, thereby improving the convenience of subsequent centralized processing of substandard tea leaves and impurities.
[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
