Description

A kind of tea drying device with airflow filtering net
Technical field
This application involves drying unit field, specially a kind of tea drying device with airflow filtering net.
Background technique
In some drying machinery fields, especially in drying tea leaves machinery field, often using blow drying with incite somebody to action Moisture, which is blown away, to be left near tealeaves.In order to guarantee that tealeaves is equably dried, often in the whole circumference of drying unit comprehensively Blow openings are uniformly arranged, to purge the entire periphery of tealeaves conveyer belt.
But for tealeaves in the overall drying process, the distribution of moisture is often non-uniform, 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 overturning towards some preferential direction, it is difficult to directly turn over the side of tealeaves or bottom surface It is dynamic.
Moreover, because the features such as operation characteristic of air-flow and more quantity of airflow channel, the resistance of this airflow channel Plug situation tends to occur still to be not easy to be found, or is not easy to be overcome or corrected at once.This is carried out continuously Production brings mass defect.And shut down and safeguarded, production efficiency can be reduced and bring additional production cost.
Summary of the invention
The purpose of the present invention is to provide a kind of tea drying devices with airflow filtering net, can overcome existing skill Drawbacks described above in art.
According to the present invention, a kind of tea drying device with airflow filtering net, including symmetrical drying in structure Airflow blow, the drying airflow blow includes the annular for being provided with axially extending cylindric air blowing drying channel Body part and the ring that the annular body portion is supported on the annular body portion and accommodated by radial struts Shape casing part, be provided in the annular body portion in the axial direction equally distributed a plurality of radial air blowing air flue with will Air-flow is inputted along the radial direction of the cylindric air blowing drying channel, and the air blowing drying channel is used for for carrying tealeaves Net formula conveyer belt passes through, and is the distribution of air flow chamber of annular between the annular outer cover part and the annular body portion, uses It is inputted in receiving air-flow and by distribution of air flow to a plurality of radial air blowing air flue, the left and right ends of the distribution of air flow chamber are divided It is not symmetrically provided with revolvable two air-flows input closed-loop of the mutual mirror symmetry in structure, wherein described two The air-flow input channel an of axial direction is provided in each of air-flow input closed-loop, and for described two air-flows It inputs for the air-flow input closed-loop on right side in closed-loop, the left end of the air-flow input closed-loop and the annular body portion / connected by left side bearing and inner seal ring is rotated by left side in the left side of the left side bearing and seal cooperation, institute It states and cooperation is sealed by left side rotation exterior seal ring between air-flow input closed-loop and the annular outer cover part;The drying What the left and right sides of airflow blow respectively symmetrically was fixedly connected in structure mutual mirror symmetry includes main ring Two air-flow input channel components in shape portion, for the air-flow input channel on the right side in described two air-flow input channel components For component, left side is fixedly installed convex extension part to stretch out to input the air-flow towards the air blowing drying channel Channel component positioning, each of described two air-flow input channel components are in the periphery difference around the main body ring part Air cavity shell is provided with to form the annular with air-flow input port between the air cavity shell and the main body ring part Air cavity is provided with airflow filtering net to filter out biggish particle and dust in air-flow, the gas in the air-flow input port Strainer is flowed through to be made of metal material, for described two air-flows input closed-loop in right side air-flow input closed-loop and Speech, right end extend into the annular air cavity, connect between the outer circumference surface of the main body ring part by right bearing and Lead on the right side of the right bearing by the sealing cooperation of right side rotating interior seal circle, and with the inner peripheral surface of the air cavity shell It crosses right side rotation exterior seal ring and seals cooperation;Left and right is respectively arranged at the left and right ends of the drying airflow blow Symmetrical two driving motors, the driving motor include outer rotor and the inner stator that is arranged in the outer rotor, it is described in Stator is fixed on the upside of the annular outer cover part Yu the air cavity shell, and it is outer that the outer rotor is fixed on the annular Between the shell parts and the air cavity shell and periphery of the outer rotor is provided with rotor gear accordingly to set with fixation The gear part engagement in the middle part of air-flow input closed-loop is set, each air-flow input channel component is along central axis side To being provided with tea leaf delivery channel to be connected to the air blowing drying channel and the net formula conveyer belt is supplied to pass through;Gas as a result, Stream is by each air-flow input port input to input the air-flow input channel in closed-loop via the air-flow To in the distribution of air flow chamber, and then via a plurality of radial air blowing air flue and in the air blowing drying channel that arrives to holding The tealeaves being loaded on the net formula conveyer belt carries out air blowing drying, and the outer rotor of each driving motor can drive corresponding Air-flow input closed-loop rotation is to change the circumferential position of the air-flow input channel.
Through the invention, closed-loop is inputted due to the provision of the symmetrical air-flow that can be rotated, is able to use list One airflow channel and the circumferential position that air-flow supply is rotated and selected to the single airflow channel, thereby, it is possible to be formed in Reinforcement air-flow on a certain preferential direction, that is, in the circumferential close to the insufflation channel of the single airflow channel often have compared with Air volume, so as to carry out emphasis purging to the heavier region of moisture as needed, moreover, using this selected direction Reinforcement air-flow, what can slightly be measured to tealeaves in prolonged technical process stirs, thus be easy to its bottom surface or Side drying.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 two this single airflow channels is enabled to transport in same phase or out of phase Row, to carry out comprehensive purging to the tealeaves in same distance segment.And it then can be improved tea using penetrating net formula conveyer belt Permeability of the leaf on bottom surface cooperates this comprehensive air blowing to purge drying.The gas not blocked to little obstruction or completely Circulation road is carried out selective close and is compensated to its windage loss, and thus, it is possible to correct the even property of the circumferential asymmetry of air-flow.? Maintenance phase, the rotation that closed-loop can be inputted by the air-flow carry out rapid purging to a plurality of radial air blowing air flue, To remove wherein remaining bits shape object or floccule.By the way that discrete air-flow input channel component is arranged, the air-flow is enabled to Input closed-loop is easily installed and safeguards, and is easily installed driving motor.The setting of outer rotor, and can so that compact-sized Transmission link is reduced, the driving of air-flow input closed-loop is adapted to.Whole device stabilized structure is reliable, and performance is stable and is convenient for Maintenance.
