Description

Technical Field

[0001] This utility model relates to a drying device and belongs to the technical field of drying equipment. Background Technology

[0002] Drying is a crucial step in tea processing. Its main functions are to remove moisture from the tea leaves, set their shape, and enhance their aroma. The quality of the drying directly affects the quality of the raw tea. However, traditional drying methods generally use wood, coal, diesel, etc., as heating energy sources, which not only causes significant environmental pollution and energy waste, but also makes it difficult to effectively control the drying time, resulting in inconsistent tea drying quality. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a drying device that solves the problem that the existing drying methods generally use wood, coal, diesel and other materials as heating energy, which not only causes great pollution to the environment and wastes a lot of energy, but also makes it difficult to effectively control the drying time of tea, resulting in difficulty in guaranteeing the drying quality of tea.

[0004] The technical problem to be solved by this utility model is achieved by the following technical solution: A drying device includes a support plate, a heating shell is provided on the support plate, the heating shell is a cavity structure, an air inlet communicating with the cavity structure is provided on the heating shell, an air outlet communicating with the cavity structure is provided on the heating shell, a motor is fixedly provided on the outside of the heating shell, a rotating shaft is poweredly connected to the output end of the motor, one end of the rotating shaft extends into the interior of the cavity structure and an impeller is fixedly provided thereon, and a shock-absorbing structure is provided on the support plate, the shock-absorbing structure is used to buffer and dampen the heating shell.

[0005] By adopting the above technical solution, when using this device, the heating shell is first moved to a suitable drying position. Then, the motor is connected to an external power source to provide power to the motor. The motor is then started to drive the rotating shaft to rotate, which in turn drives the impeller to rotate. The rotation of the impeller generates an air pressure difference. At this time, external air is drawn into the cavity structure through the air inlet. The air is heated by friction between the impeller 7 and the air. The heated air is then blown out through the air outlet 4 to heat and dry the tea leaves. This device heats the drawn-in air and blows it out by driving the impeller to rotate with the motor, achieving a relatively efficient air circulation heating process. Compared with traditional methods, it can make fuller use of energy and reduce energy waste. By controlling the start and stop of the motor and its speed, the drying time can be precisely controlled, which helps to improve the drying quality.

[0006] The present invention is further configured such that: the shock absorption structure includes a positioning groove formed on the support plate, a positioning frame is fixedly set on the heating shell, a positioning plate is fixedly set on the positioning frame, the positioning plate and the positioning groove are slidably connected, a plurality of dampers are set between the positioning plate and the positioning groove, and springs are sleeved on the outer surface of the plurality of dampers, and the two ends of the springs are fixedly connected to the positioning groove and the positioning plate respectively.

[0007] By adopting the above technical solution, during the drying process, the operation of the motor may cause vibration of the heating shell. At this time, the heating shell will transmit the vibration to the positioning frame, causing it to drive the positioning plate to slide in the positioning groove. During the sliding process, the positioning plate compresses the damper and spring. The compression of the damper and spring absorbs the vibration generated during the operation, thereby improving the stability of the device.

[0008] The present invention is further configured such that a movable wheel is rotatably mounted on the support plate, and a limit structure is provided on the support plate. A mounting plate is fixedly mounted on the support plate, and a threaded rod is threaded on the mounting plate. A limit plate is rotatably mounted on one end of the threaded rod, and a rotating block is fixedly mounted on the other end of the threaded rod.

[0009] By adopting the above technical solution, the entire device can be easily moved by the moving wheels to adapt to different drying scenarios. When it is moved to a suitable position, the rotating block drives the threaded rod to rotate, and then the threaded rod drives the limiting plate to move towards the ground and abut against the ground, thus preventing the moving wheels from moving accidentally during the drying process.

[0010] The present invention is further configured such that: two protective frames are fixedly installed on the support plate, the two protective frames are used to protect the heating shell, and a filter structure is provided between the two protective frames, the filter structure is used to filter the air adsorbed by the air inlet.

[0011] By adopting the above technical solution, the heating shell is protected by a protective frame during the drying process. The protective frame can act as an isolation device, preventing operators from accidentally coming into contact with the high-temperature heating shell and reducing the risk of burns. During the movement process, the protective frame can prevent external objects from directly contacting the heating shell, thus extending the service life of the device.

[0012] The present invention is further configured such that: the filter structure includes a guide groove opened on the protective frame, a guide block is slidably arranged inside the guide groove, a filter plate is fixedly arranged between the guide blocks, the filter plate can abut against the air inlet, a handle is provided on the filter plate, and a fixing bolt is threaded on the protective frame, one end of the fixing bolt extends into the interior of the guide groove and abuts against the guide block.

[0013] By adopting the above technical solution, when the air inlet draws in air, the filter plate filters out dust and impurities in the air, ensuring that the incoming air is clean and further improving the quality of the tea. When the filter plate may become clogged after a long time, first, turn the fixing bolt to remove the limit of the guide block, and then pull the handle to move the filter plate. Then, the filter plate drives the guide block to slide in the guide groove, which can quickly drive the filter plate to be replaced and cleaned.

[0014] The beneficial effects of this invention are as follows: When using this device, firstly, the heating shell is moved to a suitable drying position. Then, the motor is connected to an external power source to provide power. Starting the motor drives the rotating shaft to rotate, which in turn drives the impeller to rotate. The rotating impeller generates a pressure difference, at which point external air is drawn into the heating shell through the air inlet for heating. The heated air is then blown out through the air outlet to heat and dry the tea leaves. This device achieves a relatively efficient air circulation heating process by using a motor to drive the impeller to heat and blow out the air. Compared to traditional methods, this method makes fuller use of energy and reduces energy waste. By controlling the start / stop and speed of the motor, precise control of the drying time can be achieved, which helps improve the drying quality. Attached Figure Description

[0020] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this utility model, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0021] like Figures 1 to 3 As shown, a drying device includes a support plate 1, a heating shell 2 mounted on the support plate 1, the heating shell 2 being a cavity structure 201, an air inlet 3 communicating with the cavity structure 201, an air outlet 4 communicating with the cavity structure 201, a motor 5 fixedly mounted on the outside of the heating shell 2, the motor 5 being connected to an external power source to provide power, a frequency converter mounted on the motor 5, and a temperature sensor mounted on the air outlet 4. The temperature sensor and the frequency converter are electrically connected. The motor 5 is controlled by a temperature sensor and a frequency converter. Based on real-time temperature feedback, the air intake ratio is dynamically adjusted to form a closed-loop temperature control logic, which accurately controls the drying temperature fluctuation within ±10℃, and achieves precise and adaptive adjustment of the drying chamber temperature. The output end of the motor 5 is connected to a rotating shaft 6. One end of the rotating shaft 6 extends into the cavity structure 201 and is fixedly equipped with an impeller 7. The air inlet 3 intakes air along the axial direction of the rotating shaft 6, and the air outlet 4 delivers air along the tangential direction of the rotating shaft 6. A shock-absorbing structure is provided on the support plate 1.

[0022] like Figure 4 As shown, the damping structure includes a positioning groove 1011 vertically formed on the support plate 1. A positioning frame 1012 is fixedly mounted on the heating shell 2, and a positioning plate 1013 is fixedly mounted on the positioning frame 1012. The positioning plate 1013 and the positioning groove 1011 are slidably connected. The positioning plate 1013 reciprocates along the opening direction of the positioning groove 1011. A plurality of dampers 1014 are arranged between the positioning plate 1013 and the positioning groove 1011. The outer surface of the plurality of dampers 1014... A spring 1015 is fitted onto the heating housing. The two ends of the spring 1015 are fixedly connected to the positioning groove 1011 and the positioning plate 1013, respectively. The direction of the spring force of the spring 1015 is the same as the sliding direction of the positioning plate 1013. When the heating housing 2 and the support base 1 are not on the same plane under different working environments, the shock absorption structure can also be set as a support frame and a buffer pad. The heating housing 2 is supported by the support frame to make it parallel to the support base 1. Then, a buffer pad is filled between the support frame and the heating housing 2 to buffer the heating housing.

[0023] like Figure 2As shown, a movable wheel 1021 is rotatably mounted on the support plate 1, which facilitates the movement of the entire device. A mounting plate 1031 is fixedly mounted on the support plate 1. There are two mounting plates 1031, which are fixedly mounted on opposite sides of the support plate 1. A threaded rod 1032 is threaded onto the mounting plate 1031. A limit plate 1033 is rotatably mounted on one end of the threaded rod 1032. The limit plate 1033 is used to contact the ground to provide limit support for the entire device. A rotating block 1034 is fixedly mounted on the other end of the threaded rod 1032, which allows the threaded rod 1032 to be rotated easily.

[0024] like Figure 1 As shown, two protective frames 1041 are fixedly installed on the support plate 1. The two protective frames 1041 are used to protect the heating shell 2, and a filter structure is provided between the two protective frames 1041.

[0025] like Figure 4 As shown, the filter structure includes a guide groove 1051 opened on the protective frame 1041. The guide groove 1051 is vertically opened, and a guide block 1052 is slidably arranged inside the guide groove 1051. The guide block 1052 slides along the opening direction of the guide groove 1051. A filter plate 1053 is fixedly arranged between the guide blocks 1052. The filter plate 1053 can move synchronously with the guide blocks 1052. The filter plate 1053 can abut against the air inlet 3. The filter plate 1053 is used to filter impurities in the air. A handle 1054 is provided on the filter plate 1053. A fixing bolt 1055 is threaded on the protective frame 1041. The fixing bolt 1055 can limit the position of the filter plate 1053 to prevent accidental movement. One end of the fixing bolt 1055 extends into the interior of the guide groove 1051 and abuts against the guide block 1052.

[0026] When using this device, first move the heating housing 2 to a suitable drying position, then connect the motor 5 to an external power source to power the motor 5. Then, start the motor 5 to drive the rotating shaft 6 to rotate, and the rotating shaft 6 drives the impeller 7 to rotate. The rotation of the impeller 7 generates an air pressure difference. At this time, external air is drawn into the cavity structure 201 through the air inlet 3. The air is heated by friction between the impeller 7 and the air. The heated air is then blown out through the air outlet 4 to heat and dry the tea leaves. This device heats the drawn-in air and blows it out by driving the impeller 7 with the motor 5, achieving a relatively efficient air circulation heating process. Compared with traditional methods, it can make fuller use of energy and reduce energy waste. By controlling the start, stop and speed of the motor 5, the drying time can be precisely controlled, which helps to improve the drying quality.

[0027] During the drying process, the operation of the motor 5 may cause vibration of the heating shell 2. At this time, the heating shell 2 will transmit the vibration to the positioning frame 1012, which will drive the positioning plate 1013 to slide in the positioning groove 1011. During the sliding process, the positioning plate 1013 compresses the damper 1014 and the spring 1015. The compression of the damper 1014 and the spring 1015 absorbs the vibration generated during the operation, thereby improving the stability of the device.

[0028] The moving wheels 1021 allow the entire device to be moved easily to adapt to different drying scenarios. Once the device is in the right position, the rotating block 1034 drives the threaded rod 1032 to rotate. Then, the threaded rod 1032 drives the limiting plate 1033 to move towards the ground and make contact with the ground, thus preventing the moving wheels 1021 from moving accidentally during the drying process.

[0029] During the drying process, the heating shell 2 is protected by the protective frame 1041. The protective frame 1041 can act as an isolation device to prevent operators from accidentally coming into contact with the high temperature heating shell 2, thus reducing the risk of burns. During the movement process, the protective frame 1041 can prevent external objects from directly contacting the heating shell 2, thus extending the service life of the device.

[0030] When the air inlet 3 draws in air, it filters dust and impurities from the air through the filter plate 1053 to ensure that the incoming air is clean and further improve the quality of the tea. If the filter plate 1053 becomes clogged after a long period of time, firstly, the guide block 1052 can be removed by rotating the fixing bolt 1055. Then, the filter plate 1053 can be moved by pulling the handle 1054. The filter plate 1053 then drives the guide block 1052 to slide in the guide groove 1051, which allows for quick replacement and cleaning of the filter plate 1053.
