Description

Tea vibrating screen

Technical Field

The invention belongs to the technical field of tea processing, and particularly relates to a tea vibrating screen.

Background

In the course of working of tealeaves, can often use shale shaker equipment, tealeaves is put on the shale shaker, has the sieve mesh on the shale shaker, and through continuous vibration, tealeaves disperses, and the garrulous being removed by the sieve mesh of tealeaves wherein makes the tealeaves that finally obtains more even.

The existing vibrating screen equipment generally has only the function of screening tea dust, and the function is single.

Disclosure of Invention

The invention aims to provide a tea vibrating screen, which aims to solve the problem of single function of the existing tea vibrating screen.

The tea vibrating screen comprises a frame, wherein an inclined screen plate and a vibration exciter for driving the screen plate to vibrate are arranged on the frame, a plurality of screen holes are formed in the screen plate, a roller capable of freely rotating and a motor for driving the roller to rotate are arranged below the screen plate, the roller is obliquely arranged, the central axis of the roller is parallel to the screen plate, a fan is arranged at one end of the roller, and a plurality of ventilation holes are formed in the roller; the utility model discloses a screen plate, including the screen plate, the screen plate is equipped with the baffle in length direction's both sides, the screen plate is equipped with stop gear in higher end department, stop gear includes backup pad and limiting plate, the backup pad has two, connects in the both sides of screen plate respectively, be equipped with rectangular shape slide hole in the backup pad, the both ends of limiting plate all are equipped with the bolt, and two bolts pass the slide hole of two backup pads respectively, are fixed in the backup pad through the nut, the limiting plate is located the top of screen plate.

The working principle and the beneficial effects of the invention are as follows:

when the vibrating screen is used, the vibrating screen not only can be used for screening common tea, but also can be used for tea with higher leaf temperature just after drying or de-enzyming, and when the vibrating screen is used for the type of high Wen Chashe, the vibrating screen not only has the function of vibrating screening, but also has the function of quickly cooling the tea. The specific principle is as follows: the tealeaves of high temperature gets into the sieve from the higher section of sieve, and on the basis of sieve slope and constantly vibrating, can slide to lower end, owing to there is the cylinder below of sieve, and there is the fan one end of cylinder, and when the fan blows the wind to the cylinder, wind can blow out from the ventilation hole on the cylinder, because the axis of cylinder is parallel with the sieve, consequently the wind that the ventilation hole blown out can spread over whole sieve, then blows to tealeaves from the sieve mesh department on the sieve, takes away the heat of tealeaves, plays the effect of rapid cooling. And when the tea leaves vibrate, larger gaps are reserved between the tea leaves, wind energy flows between the tea leaves better, more heat is taken away rapidly, and the cooling effect is better.

In the application, the baffle plate plays a role in preventing tea leaves from sliding off the sieve plate in the process of vibration. The limiting plate is used for limiting the thickness of the tea on the sieve plate, and because the thicker the tea is, the less ideal the effect of screening or cooling is, and the limiting plate is positioned above the sieve plate, so that the thicker tea can be spread to be thin, and the thickness of the tea is uniform. And the distance between the limiting plate and the sieve plate can be adjusted, when thicker tea leaves are needed, the nut is unscrewed, the toggle bolt moves upwards in the sliding hole, the limiting plate moves upwards along with the toggle bolt, and then the nut is screwed up to achieve the effect of adjusting the height of the limiting plate.

Further, the bottom of frame is equipped with the gyro wheel, when needs remove the shale shaker like this, promote its removal can, need not to move, more laborsaving.

Further, the frame below is equipped with the telescopic link, is equipped with the spring lock and the lockhole that are used for fixed on the telescopic link, and spring lock and lockhole phase-match because the shale shaker is when the vibration, if the below is supported by the gyro wheel, lets the gyro wheel damage easily, reduces its life. The effect of this design lies in, when needs remove the shale shaker, shortens the telescopic link, utilizes the gyro wheel to support to remove, when needs use the shale shaker, with the telescopic link extension, the spring lock inserts in the lockhole, and is fixed with the telescopic link, and the height of telescopic link is greater than the gyro wheel this moment, supports the shale shaker because the telescopic link, has avoided the gyro wheel to support, can effectively improve the life of gyro wheel.

Further, the below of the lower end of sieve is equipped with the deceleration strip, the deceleration strip is fixed in the frame, and the tealeaves that drops downwards from the lower end of sieve hits the deceleration strip in the sky, causes temporary deceleration, increases the time of tealeaves in the sky, lets the cooling effect of tealeaves better.

Detailed Description

The invention is described in further detail below by way of specific embodiments:

reference numerals in the drawings of the specification include: frame 1, sieve 2, vibration exciter 3, first motor 4, cylinder 5, second motor 6, fan 7, baffle 8, backup pad 9, slide opening 10, limiting plate 11, bolt 12, nut 13, gyro wheel 14, telescopic link 15, deceleration strip 16.

As shown in fig. 1 and 2, the invention provides a tea vibrating screen, which comprises a frame 1, wherein an inclined screen plate 2 and a vibration exciter 3 for driving the screen plate 2 to vibrate are arranged on the frame 1, the vibration exciter 3 is connected with a first motor 4, a plurality of screen holes are formed in the screen plate 2, a roller 5 capable of freely rotating and a second motor 6 for driving the roller 5 to rotate are arranged below the screen plate 2, the roller 5 is obliquely arranged, the central axis of the roller 5 is parallel to the screen plate 2, one end of the roller 5 is provided with a fan 7, and a plurality of ventilation holes are formed in the roller 5; the screen plate 2 is equipped with baffle 8 in length direction's both sides, and screen plate 2 is equipped with stop gear in higher end department, and stop gear includes backup pad 9 and limiting plate 11, and backup pad 9 has two, connects respectively in the both sides of screen plate 2, is equipped with rectangular shape slide hole 10 in the backup pad 9, and the both ends of limiting plate 11 all are equipped with bolt 12, and two bolts 12 pass the slide hole 10 of two backup pads 9 respectively, are fixed in backup pad 9 through nut 13, and limiting plate 11 is located the top of screen plate 2. The bottom of frame 1 is equipped with gyro wheel 14, and frame 1 below is equipped with telescopic link 15, is equipped with latch and lockhole that are used for fixed on the telescopic link 15, and latch and lockhole assorted are equipped with deceleration strip 16 below the lower end of sieve 2, and deceleration strip 16 is fixed in on the frame 1.

In the concrete implementation of the invention, high-temperature tea leaves enter the sieve plate 2 from the higher section of the sieve plate 2, slide towards the lower end on the basis of the inclination and continuous vibration of the sieve plate 2, and because the roller 5 is arranged below the sieve plate 2, a fan 7 is arranged at one end of the roller 5, when the fan 7 blows air to the roller 5, the air can be blown out from the ventilation holes on the roller 5, and because the central axis of the roller 5 is parallel to the sieve plate 2, the air blown out from the ventilation holes can spread over the whole sieve plate 2, and then the tea leaves are blown from the sieve holes on the sieve plate 2, so that the heat of the tea leaves is taken away, and the effect of rapid cooling is achieved. And when the tea leaves vibrate, larger gaps are reserved between the tea leaves, wind energy flows between the tea leaves better, more heat is taken away rapidly, and the cooling effect is better.
