Description

Technical Field

[0001] The utility model relates to the technical field of tea production auxiliary equipment, in particular to an exhaust type cooling and lifting device. Background Art

[0002] In the process of tea production, it is usually necessary to use various conveying devices to transport tea between multiple processes, such as conveying devices and lifting devices. For example, after the tea leaves are withered, a lifting device is needed to lift them to the feeding port of the next process. The lifting device is generally an inclined conveyor. The lower end of the conveyor is located below the discharge end of the withering device. After the material is connected, it is lifted to the higher end and then falls to the next process below. In the actual production process, the tea leaves after withering have a higher temperature. After being lifted to the next process, it needs to be cooled to avoid the high temperature affecting the normal processing of the next process. However, this leads to the lengthening of the process and takes up more time. At the same time, it also makes the processing production line occupy a larger area, which ultimately leads to an increase in the overall production cost. Utility Model Content

Therefore, there is no need to perform cooling operations after lifting (or the length of the cooling operation process can be shortened), which solves the problem in the prior art that a cooling process needs to be added, resulting in a larger production line area and longer processing time.

[0021] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0022] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0023] In an exemplary embodiment, Figure 1-4 As shown, this embodiment provides an exhaust-type cooling and lifting device, which includes a hoist 1, a top fixed cover of the hoist 1 is provided with a protective cover 2, a plurality of exhaust fans 3 are fixedly connected inside the protective cover 2, and the exhaust fans 3 are arranged equidistantly in sequence in the lifting direction of the hoist 1, and a protective net 4 located above the exhaust fans 3 is also installed on the protective cover 2; a plurality of arc rods 5 are also provided inside the protective cover 2, which are located below the exhaust fans 3 and whose two ends are respectively fixedly connected to the inner walls of both sides of the protective cover 2, and all the arc rods 5 are equidistantly arranged from one end of the protective cover 2 to the other end.

[0024] In the above embodiment, during the lifting process of the material (i.e., tea leaves), the exhaust fan 3 is started to assist in dissipating the heat in the material to the outside, thereby achieving the purpose of cooling. Therefore, there is no need to perform cooling operation after lifting (or the length of the cooling operation process can be shortened), which solves the problem in the prior art that the cooling process needs to be added, resulting in a larger production line area and longer processing time; Figure 2 As shown in the figure, the arrow is a schematic diagram of the airflow direction when the exhaust fan 3 is running. In this way, during the material lifting process, the heat will pass through the exhaust fan 3 and the protective net 4 upward with the airflow, and then leave the protective cover 2, and the temperature of the material can be reduced; the arc rods 5 are set up because there are small intervals between these arc rods 5, which do not block the airflow, but can prevent some materials from being sucked up by the exhaust fan 3 and then accidentally sucked into the exhaust fan 3. At the same time, Figure 1 , 3 As shown, these arc rods 5 can also be used for the attachment of wires 7 to smoothly supply power to each exhaust fan 3 through an external power supply; in a more specific solution, mounting bars 6 are fixedly connected to the inner walls on both sides of the protective cover 2, and both ends of all the arc rods 5 are fixedly connected to the two mounting bars 6 respectively. A unified installation base is provided for the arc rods 5 through two mounting rods 13, which can improve the stability of the arc rods 5.

[0025] In a further exemplary embodiment, Figure 1 , 2As shown in Figures 3 and 4, a mounting frame 8 is provided on the top surface of the protective cover 2, and the protective net 4 is installed in the mounting frame 8. Accordingly, the mounting frame 8 is a long strip extending from the lower end of the protective cover 2 to the higher end, and the cross section is also arc-shaped. The surroundings of the protective net 4 are against the inner wall of the mounting frame 8, thereby covering the mounting frame 8. At the same time, all exhaust fans 3 have a vertical projection on the protective net 4, so that when the exhaust fan 3 is running, the exhaust air can be smoothly discharged through the protective net 4, and the set protective net 4 can prevent external impurities from falling into the protective cover 2, thereby preventing external impurities from entering the elevator 1 or falling into the exhaust fan 3.

[0026] In a more detailed exemplary embodiment, Figure 1 , 2 As shown in Figure 3, both ends of the protective net 4 are connected to the protective cover 2 through a plurality of Z-shaped connectors. Specifically, the Z-shaped connector includes a first connecting plate 9, an intermediate plate 10 and a second connecting plate 11 that are fixedly connected in sequence. The first connecting plate 9 is connected to the outer wall surface of the protective cover 2, the second connecting plate 11 is connected to the outer wall surface of the protective net 4, and the intermediate plate 10 is against the inner wall of the mounting frame 8. In this way, the protective net 4 can be located within the mounting frame 8 on all sides, and the installation is more stable and the covering effect is better. Furthermore, the second connecting plate 11 can be directly fixed to the protective net 4, such as by welding, and the first connecting plate 9 can be detachably connected, such as by connecting to the protective cover 2 through screws. This makes it convenient to disassemble and assemble the protective net 4 and facilitate subsequent maintenance and installation.

[0027] In a more detailed exemplary embodiment, Figure 1-4 As shown, the protective cover 2 is also fixedly connected with a plurality of mounting frames located between the arc rod 5 and the protective net 4, each mounting frame is for mounting a row of fans 3, and the mounting frame includes a mounting ring 12 fixedly surrounding the outside of the discharge machine, and at least one pair of mounting rods 13 fixedly connected to the outside of the mounting ring 12, and the two mounting rods 13 are respectively fixedly connected to the inner walls on both sides of the protective cover 2, and each row of fans 3 can be installed separately through the mounting frame, which is convenient for subsequent separate disassembly and maintenance.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
