Description

A kind of noise reducing type tea drying device
Technical field
The application is related to drying unit field, specially a kind of noise reducing type tea drying device.
Background technology
In some drying mechanical fields, especially in the mechanical field of drying tea leaves, often dried using blowing with incite somebody to action Moisture, which is blown away, to be left near tealeaves.In order to ensure that tealeaves is equably dried, often in the whole circumference of drying unit comprehensively Blow openings are uniformly arranged, to purge the whole periphery of tealeaves conveyer belt.
But, for tealeaves in the overall drying process, its moisture distribution often it is uneven, this for More times are often wasted for the drying unit uniformly blown by whole drying tea leaves.Moreover, this uniform Air blowing is often difficult to cause for tealeaves in the upset towards some preferential direction, it is difficult to directly turn over the side or bottom surface of tealeaves It is dynamic.
Be additionally, since air-flow operation characteristic and gas channel quantity it is more the features such as, the resistance of this gas channel Plug situation tends to occur but is not easy to be found, or is not easy to be overcome or corrected at once.This gives what is be carried out continuously Production brings mass defect.And shut down and safeguarded, production efficiency can be reduced and extra production cost is brought.
The content of the invention
It is an object of the invention to provide a kind of noise reducing type tea drying device, it can overcome of the prior art above-mentioned Defect.
According to the present invention, a kind of noise reducing type tea drying device, including symmetrical drying airflow blow dress in structure Put, it is described drying airflow blow include be provided with the annular body portion of axially extending cylindric air blowing drying channel with And it is supported on the annular body portion and accommodates the annular outer cover part of the annular body portion by radial struts, Be provided with the annular body portion in the axial direction equally distributed a plurality of radial direction air blowing air flue with by air-flow along institute The radial direction input of cylindric air blowing drying channel is stated, the air blowing drying channel is used for the net formula conveyer belt for carrying tealeaves Pass through, be the distribution of air flow chamber of annular between the annular outer cover part and the annular body portion, for receiving air-flow Input and by distribution of air flow to a plurality of radial direction air blowing air flue, the left and right ends of the distribution of air flow chamber respectively symmetrically are set Revolvable two air-flows input closed-loop of the mutual specular in structure is equipped with, wherein, described two air-flow input envelopes The air-flow input channel of an axial direction is provided with each in closed loop, and closed-loop is inputted for described two air-flows For the air-flow input closed-loop on middle right side, pass through between the left end and the annular body portion of the air-flow input closed-loop The connection of left side bearing and passing on left left side rotation inner seal ring and seal cooperations in the left side bearing, the air-flow is inputted Exterior seal ring is rotated by left side between closed-loop and the annular outer cover part and cooperation is sealed;The drying airflow blow dress The left and right sides put respectively symmetrically is fixedly connected with two that include main body ring part of the mutual specular in structure Air-flow input channel component, for the air-flow input channel component on the right side in described two air-flow input channel components, Its left side is fixedly installed convex extension part and is used to stretch out so as to the air-flow input channel component towards the air blowing drying channel Each in positioning, described two air-flow input channel components is respectively arranged with gas in the periphery around the main body ring part Cavity shell so as between the air cavity housing and the main body ring part formed with air-flow input port annular air cavity, for For the air-flow input closed-loop on the right side in described two air-flow input closed-loops, its right-hand member extend into the annular air cavity In, it is connected and is revolved on the right side of the right bearing by right side by right bearing between the outer circumference surface of the main body ring part Turn inner seal ring sealing cooperation, and exterior seal ring is rotated by right side with the inner peripheral surface of the air cavity housing and seals and matches somebody with somebody Close;Symmetrical two motors, the drive are respectively arranged with the left and right ends of the drying airflow blow Dynamic motor includes outer rotor and the inner stator being arranged in the outer rotor, and the inner stator is fixed on the annular outer cover portion Divide the upside with the air cavity housing, the outer rotor is fixed between the annular outer cover part and the air cavity housing simultaneously And the periphery of the outer rotor is provided with rotor gear to accordingly with being fixedly installed in the middle part of the air-flow input closed-loop Gear part engagement, the motor periphery is coated with one layer of silencing cotton, and the silencing cotton is to reduce the motor The noise operationally produced, each air-flow input channel component is provided with tea leaf delivery channel along central axial direction To be connected with the air blowing drying channel and supply the net formula conveyer belt to pass through;Thus, air-flow is defeated by each air-flow Entrance input so as to via the air-flow input closed-loop in the air-flow input channel and in the distribution of air flow chamber that arrives, And then via a plurality of radial direction air blowing air flue to being carried on the net formula conveyer belt in the air blowing drying channel that arrives Tealeaves carry out air blowing drying, the outer rotor of each motor can drive corresponding air-flow input closed-loop rotation from And change the circumferential position of the air-flow input channel.
By the present invention, due to inputting closed-loop there is provided the symmetrical air-flow that can be rotated, it can use list One gas channel and the circumferential position for being rotated to the single gas channel and selecting air-flow to supply, thereby, it is possible to be formed Reinforcement air-flow on a certain preferential direction, that is, in the circumferential close to the single gas channel insufflation channel often have compared with Air volume, carries out emphasis purging, moreover, using this selected direction so as to region heavier to moisture as needed Reinforcement air-flow, tealeaves slightly can be measured in prolonged technical process stirs, thus be easy to its bottom surface or Side is dried up.And the symmetrical this air-flow input closed-loop that can be rotated in left and right ends is set, it can be ensured that air-flow is in axial direction Flow loss on direction is minimum, and enables to two this single gas channels to be transported in same phase or out of phase OK, with the purging comprehensive to the tealeaves progress in same distance segment.And can then improve tea using penetrating net formula conveyer belt Permeability of the leaf on bottom surface, coordinates this comprehensive air blowing purging drying.The gas not blocked to little obstruction or completely Circulation road carries out selective close and its windage loss is compensated, thus, it is possible to the even property of circumferential asymmetry for correcting air-flow. Maintenance phase, the rotation of closed-loop can be inputted by the air-flow and rapid purging is carried out to a plurality of radial direction air blowing air flue, To remove the bits shape thing or floccule that wherein remain.The air-flow input channel component discrete by setting, enables to the air-flow Input closed-loop is easily installed and safeguarded, and is easily installed motor.The setting of outer rotor causes compact conformation, and can Transmission link is reduced, is adapted to the driving that the air-flow inputs closed-loop.Whole device stabilized structure is reliable, and performance is stablized and is easy to Safeguard.
