Description

Technical Field

[0001] The utility model relates to a drying device, in particular to a drying device for processing bamboo sticks. Background Art

[0002] During the production of bamboo sticks, the processed bamboo sticks need to be dried in order to increase the hardness and strength of the bamboo, prevent the bamboo from mildew and decay, and reduce the weight and volume of the bamboo.

[0003] During conventional drying work, bamboo sticks are usually placed in batches on a tray or a bracket, and then the tray or the bracket is placed in a high-temperature oven for baking at a fixed time and temperature. During this process, the bamboo sticks are in a stationary state. If the existing drying equipment is to achieve an ideal drying effect, it is necessary to avoid stacking of the bamboo sticks to reduce the shading caused by the stacking of the bamboo sticks during baking. In this case, the bamboo sticks need to be manually placed neatly on the tray or the bracket. Such operation requires a large amount of labor and time costs, and compared with stacking the bamboo sticks, the flat placement method requires a larger area, and the number of bamboo sticks baked and dried at one time will be limited.

[0010] Furthermore, it also includes a supporting block, and the supporting blocks are symmetrically arranged on the front and rear sides of the lower inner part of the base.

[0011] Compared with the prior art, the utility model has the following advantages: the utility model creates a drying station in the drying drum through the high temperature provided by the heating device, and during the drying process, bamboo sticks are placed by the continuously swinging circular drum, and there is no need to place them neatly. More bamboo sticks can be placed in the drum, and the bamboo sticks in the drum are always in a state of movement and rolling. In this case, the bamboo sticks will not maintain a long-term contact and adhesion state, and the heat flow can effectively contact the surface of the bamboo sticks, reducing the influence of mutual shielding of the bamboo sticks on drying, eliminating the process of artificially placing and laying the bamboo sticks, and having higher efficiency.

[0012] The utility model drives the flexible belt to rotate at a high speed through a driving motor, stirs the accumulated bamboo sticks, and at the same time makes surface contact with the bamboo sticks rolling in the drum, so as to clean up a certain amount of bamboo chips remaining on the surface of the bamboo sticks after grinding. Moreover, the airflow generated when the flexible belt rotates will disturb the heat flow transmitted from the heating device, so that the heat flow movement in the drying cylinder is more active, avoiding the accumulation of heat flow in a certain area in the drying cylinder, balancing the distribution state of the heat flow in the drying cylinder, and improving the drying effect.

[0013] The utility model connects the external dry air flow through the air duct and blows it to the inside of the blanking frame. The blown air flow can pre-cool the bamboo sticks with relatively high residual temperature received on the baffle plate after drying, so as to avoid the bamboo sticks being directly in contact with the external atmosphere to cool down and absorb heat, and water molecules in the atmosphere being attached to the bamboo sticks, causing the dried bamboo sticks to be contaminated with moisture, thus affecting the drying effect.

Selected positional descriptions in the description, such as top, bottom, lateral, etc., also refer to the directly described and shown figures and are transferred to the new positions in the case of a change in position.

[0021] Embodiment 1: A drying device for bamboo skewers, such as Figure 1-5As shown, it includes a base 1, a connecting frame 2, a drying cylinder 3, a cover plate 30, a support frame 31, a roller 32, a transmission motor 33, a gear set 34, a heating device 4 and a blanking frame 6. The base 1 is made of a relatively hard metal. A fixing hole is provided at the bottom of the base 1 for easy installation of the equipment. The upper part of the base 1 is fixedly connected with the connecting frame 2. The drying cylinder 3 is fixedly provided between the upper parts of the connecting frame 2. The drying cylinder 3 is made of an alloy material and has good internal thermal insulation performance. A wrapped heat insulation layer is provided on the outside of the drying cylinder 3. An arc-shaped opening is provided on the upper part of the drying cylinder 3. A cover plate 30 is slidably provided on the inner side of the opening at the top of the drying cylinder 3. The cover plate 30 is arc-shaped. 0 rotates inside the drying cylinder 3 to completely cover the opening of the drying cylinder 3, and the sealing between the two is better. When the cover plate 30 completely covers the opening of the drying cylinder 3, the inside of the drying cylinder 3 is a drying processing space with a closed upper part. The cover plate 30 is made of the same material as the drying cylinder 3 and has good thermal insulation performance. Similarly, a thermal insulation layer is arranged on the outside of the cover plate 30. The purpose of wrapping the cover plate 30 and the drying cylinder 3 with thermal insulation material is to avoid the high temperature in the drying cylinder 3 from being transmitted out, reduce direct contact with people, and cause injuries; support frames 31 are fixedly welded on the left and right sides of the drying cylinder 3, and the upper part of the support frame 31 is an arc-shaped support plate A roller 32 is rotatably provided between the inner sides of the arc-shaped support plates of the two support frames 31, on which bamboo sticks can be placed in batches during drying. The roller 21 can rotate smoothly in the support frame 31, and the wall of the roller 32 is hollowed out to facilitate the heat flow to enter the interior of the roller 32. The hollowed-out holes are slightly smaller than the bamboo sticks that need to be dried. When the bamboo sticks are in the roller 32, they will not fall out. The roller 32 is provided with a vacant opening for feeding and discharging: when feeding, the opening of the roller 32 needs to face the upper position, and the cover plate 30 should be in a sliding open state. When the openings of the drying cylinder 3 and the roller 32 are facing the same direction, the bamboo sticks that need to be dried are placed in the roller 32; the drying cylinder A transmission motor 33 is installed on the lower inner side of the right part. The transmission motor 33 provides rotational power to the drum 32 through a gear set 34. The gear set 34 consists of a gear plate installed on the right side of the drum 32 and a pinion installed on the output shaft of the transmission motor 33. The gear plate and the pinion are meshed with each other. When the transmission motor 33 is working, the gear set 34 controls the drum 32 to rotate alternately clockwise and counterclockwise, and the rotation amplitude is small. The bamboo sticks in the drum 32 will roll in the rotating drum 32. While ensuring that the bamboo sticks can roll with the rotation of the drum 32, it is necessary to prevent the bamboo sticks from falling from the opening of the drum 32.A heating device 4 is provided on the left side of the drying cylinder 3. The heating device 4 is used to generate heat flow during the drying process and send it into the drying cylinder 3. The high temperature provided by the heating device 4 creates a drying station in the drying cylinder 3. It does not need to be neatly arranged. More bamboo sticks can be placed in the drum 32. During the drying process, the bamboo sticks are always in a state of movement and rolling. In this case, the bamboo sticks will not maintain a long-term contact and fit state. The heat flow can effectively contact the surface of the bamboo sticks, reducing the influence of mutual shielding of the bamboo sticks on the drying process. The process of artificially placing and flattening the bamboo sticks is eliminated, and the efficiency is high. The lower part of the drying cylinder 3 is connected and connected to the blanking frame 6. When the drying work is completed, the control transmission motor 33 drives the drum 32 to rotate to the state with the opening downward. The bamboo sticks in the drum 32 will fall from the drying cylinder 3 to the blanking frame 6 along the opening under the action of gravity, and fall out of the equipment from the blanking frame 6. ;

[0022] How it works

[0023] Embodiment 2: Based on embodiment 1, Figure 2-4 As shown, it also includes a driving motor 7, a rotating shaft 71 and a flexible belt 72. A driving motor 7 with a high speed is installed on the inner side of the right part of the drying cylinder 3 through a motor bracket. The output shaft of the driving motor 7 is fixedly connected with the rotating shaft 71. The rotating shaft 71 penetrates into the inner side of the drum 32 from the center of the right end of the drum 32. A plurality of groups of flexible belts 72 are evenly spaced outside the rotating shaft in the drum 32. The number of each group of flexible belts 72 is not less than four. When the driving motor 7 drives the rotating shaft 71 to rotate at a high speed, the flexible belt 72 will stretch out under the action of centrifugal force. When the drum 3 in the drying cylinder 3 is When there are bamboo sticks inside for drying processing, the flexible belt 72, driven by the driving motor 7, will rotate and beat the bamboo sticks in the drum 32, stirring the accumulated bamboo sticks while making surface contact with the bamboo sticks rolling in the drum 32, and a certain amount of bamboo chips remaining on the surface of the bamboo sticks after grinding processing will be cleaned off, and the airflow generated by the rotation of the flexible belt 72 will disturb the heat flow transmitted from the heating device 4, making the heat flow movement in the drying cylinder 3 more active, avoiding the accumulation of heat flow in a certain area in the drying cylinder 3, balancing the distribution state of the heat flow in the drying cylinder 3, and improving the drying effect.

[0024] In a preferred embodiment: Figure 1-5 As shown, it also includes a heat-conducting block 8. No less than four semi-annular heat-conducting blocks 8 are evenly spaced on the inner wall of the drum 32. The heat-conducting blocks 8 have a good heat transfer effect. When the drying process is performed, the heat flow generated by the heating device 4 can be transferred to the drum 32 more quickly and continuously through the heat-conducting blocks 8, thereby improving the baking efficiency.

[0025] In a preferred embodiment: when it is necessary to clean the bamboo shavings cleaned by the flexible belt 72, as shown in FIG. Figure 1-4As shown, it also includes a vacuum cleaner 9, a vacuum duct 10, a baffle 121 and a torsion spring 13. A vacuum cleaner 9 with a dust removal function is fixedly installed on the front part of the base 1. The vacuum cleaner 9 is connected and communicated with the vacuum duct 10. The vacuum duct 10 is communicated with the inside of the blanking frame 6 through an air hole. When the vacuum cleaner 9 is working, a large suction force will be generated around the vacuum duct 6 to suck away the bamboo chips that fall from the roller 32 into the blanking frame 6. A rotating rod 12 is rotatably provided at the rear side of the lower part of the blanking frame 6. A baffle 121 that can receive the debris to prevent the unsucked bamboo chips from falling out of the device is fixedly connected to the rotating rod 12. The baffle 121 is horizontally placed in the blanking frame 6. Torsion springs 13 are wound around the front and rear sides of the rotating rod 12. The two ends of the torsion spring 13 are respectively connected to the rotating rod 12 and the blanking frame 6.

[0026] Under the action of the torsion spring 13, the baffle 121 will maintain a horizontal state, dividing the space in the blanking frame into upper and lower parts. The dividing part of the baffle 121 is not completely closed, and there is a gap for gas circulation. The baffle 121 can close the connecting space between the drying cylinder 3 and the blanking frame 6 while receiving the bamboo chips, effectively avoiding the heat flow escape during drying, reducing heat waste, and reducing the processing energy consumption of the heating device 4. When the bamboo sticks in the drum 32 are dried and fall downward, the baffle 121 receives the bamboo sticks. When the accumulated amount of bamboo sticks reaches a certain mass, the torsional stress of the torsion spring 13 will be less than the weight of the bamboo sticks. At this time, the baffle 121 is pushed downward, the channel in the blanking frame 6 is opened, and the bamboo sticks fall down in a concentrated manner.

[0027] In a preferred embodiment: Figure 2 and Figure 4 As shown, it also includes an air duct 11. The rear part of the blanking frame 6 is provided with the air duct 11. The rear part of the air duct 11 is connected with an air inlet joint, and the air inlet joint is used to connect an external relatively dry air source to the air duct 11. No less than three pipes are arranged on the air duct 11 at intervals, and the pipes all penetrate into the interior of the blanking frame 6. The air duct 11 is connected with the interior of the blanking frame 6. When the air duct 11 is connected to the external air source, the air flow will blow into the interior of the blanking frame 6. The blown air flow can pre-cool the bamboo sticks with relatively high residual temperature after drying and carried by the baffle 121, so as to avoid the bamboo sticks directly contacting with the outside atmosphere to cool down and absorb heat, and the water molecules in the atmosphere will adhere to the bamboo sticks, causing the dry bamboo sticks to be contaminated with moisture, affecting the drying effect.

[0028] In a preferred embodiment: Figure 1-2 As shown, it also includes a support block 14. The front and rear sides of the lower part of the base 1 are symmetrically provided with support blocks 14 that can carry square trays. People can place the tray for collecting dried bamboo sticks on the support block 14, and the bamboo sticks dropped from the blanking frame 6 can be directly collected through the tray, which is more convenient.
