Description

Technical Field:

[0001] The present invention belongs to the technical field of drying equipment, and particularly refers to a multifunctional dryer. Background Art:

[0002] In the field of post-harvest processing of crops, especially the drying treatment of cash crops such as peppers, traditional drying methods mostly use fixed brackets for sun drying or simple ovens for hot air drying. This is because peppers are crops with thin skins, high moisture content, and easy to mildew, and their drying process requires good ventilation conditions and a uniformly heated environment. The drying equipment for cereal crops mainly uses ovens, in which the grains are directly stacked in the oven for drying and heat preservation, and it is difficult to take into account the hanging drying needs of crops such as peppers that need to be thinly spread. It can be seen that drying equipment with different container structures needs to be used separately for drying economic crops such as peppers that need to be sun-dried and cereal crops, and its scope of application is narrow and the equipment cost is high. At the same time, the flow direction of the hot air in the existing dryer always remains unchanged, so the hot air drying direction received by the crops remains unchanged, and there is a phenomenon of uneven heating. Summary of the Invention:

[0003] The purpose of the present invention is to provide a multifunctional dryer, which effectively changes the flow direction of hot air in the drying chamber by means of a valve assembly, and the support base of the combined bracket is detachably connected to the bracket assembly or the oven assembly, so that it can be replaced according to the actual needs of the crops to be dried, meeting the requirements of different drying placement methods.

[0027] The present invention will be further described below with specific embodiments. Refer to Figure 1 —9:

[0028] A multifunctional dryer includes a housing 1 having a drying chamber. An air intake passage 2 and an exhaust passage 3 are provided on the housing 1. Both the air intake passage 2 and the exhaust passage 3 have two inner ports and are respectively communicated with the top and bottom of the drying chamber. Valve assemblies are respectively provided on the air intake passage 2 and the exhaust passage 3 to block one of their two inner ports. The outer port of the air intake passage 2 is connected in series with an air supply fan 4 and a heat source device 5 through a pipeline, and the outer port of the exhaust passage 3 is communicated with the outside. Among them, the valve assemblies on the air intake passage 2 and the exhaust passage 3 can respectively switch and block one of their two inner ports, so that the hot air flow can have four flow directions in the drying chamber: flowing from top to bottom, flowing from bottom to top, flowing only in the upper part, and flowing only in the lower part. In addition, the heat source device 5 can adopt a common existing biological boiler.

[0029] One or more combined supports 6 are distributed horizontally in the drying chamber. Each combined support 6 includes a support base 7. A bracket assembly or an oven assembly is detachably connected to the support base 7. The bracket assembly includes a support body 8. A plurality of layers of storage space layers are vertically spaced on the support body 8. Storage objects for placing crops to be dried are arranged in the storage space layers. The oven assembly includes an oven body 9 surrounded by a plurality of plates and having an upward opening, and the oven body 9 is used for stacking grains to be dried.

[0030] The present invention effectively changes the flow direction of the hot air in the drying chamber by means of the valve assembly, so that the hot air drying and relative humidity in the drying chamber are kept uniform, and the bracket assembly or the oven assembly can be detachably connected to the support base 7 of the combined support 6, so that it can be replaced according to the actual needs of the crops to be dried, meeting the requirements of different drying placement methods.

[0031] Furthermore, in this embodiment, the specific positions of the intake passage 2 and the exhaust passage 3 on the housing 1 are as follows: both the intake passage 2 and the exhaust passage 3 are provided on one side wall of the housing 1. The intake passage 2 is located in the middle of the corresponding side wall of the housing 1. There are two exhaust passages 3, which are respectively located on both sides of the intake passage 2.

[0032] Correspondingly, in order to facilitate the placement of the combined bracket 6 into the drying chamber, the other side of the housing 1 is a placement port communicating with the drying chamber. A placement door body 10 capable of covering and sealing the placement port is hinged at the placement port. This placement port is the access passage for the combined bracket 6 to enter and exit the drying chamber.

[0033] In order to facilitate the pushing or pulling of the combined bracket 6 into or out of the drying chamber, guiding outer plates 11 are transversely arranged on the wall surfaces of the drying chamber on both sides of the combined bracket 6, and a guiding slideway 12 is transversely arranged on the bottom surface of the drying chamber. A guiding inner plate 13 that is vertically misaligned and cooperates with the guiding outer plates 11 is arranged on the side wall of the combined bracket 6, and a moving roller 14 that is rotationally connected to the bottom of the combined bracket 6 and rolls on the guiding slideway 12 is provided.

[0034] Based on the horizontal side-by-side distribution and placement of the combined brackets 6, in order to enable hot air to flow fully and widely in the drying chamber, the inner port of the intake passage 2 is connected to a ventilation duct 15 located in the drying chamber. The ventilation duct 15 is transversely arranged above or below the combined brackets 6, and a plurality of ventilation windows 16 communicating with the drying chamber are axially opened on the ventilation duct 15.

[0035] Among them, the valve assembly can adopt a common flip-type valve structure, that is, a flip-type valve structure is provided at each inner port, and the flip-type valve structures at the two inner ports of the intake passage 2 and the exhaust passage 3 are controlled to open and close asynchronously. In this embodiment, in order to effectively control the equipment cost, the valve assembly includes a push rod motor 17 arranged on the corresponding passage. The push rod 18 of the push rod motor 17 is arranged vertically, and moving valve plates 19 that are vertically slidably matched with the corresponding passage are arranged at both ends of the push rod 18. The moving valve plates 19 are driven by the push rod motor 17 to move up and down, and when the moving valve plates 19 move up or down to the extreme values, the moving valve plates 19 can block the corresponding inner ports.

[0036] Furthermore, in order to improve the moving stability of the moving valve plate 19 sliding vertically on the housing 1, a vertical slide rail 20 is vertically erected on the outer wall of the intake passage 2 or the exhaust passage 3. A valve strip hole is axially opened on the wall surface of the intake passage 2 or the exhaust passage 3 along the axis of the vertical slide rail 20. The moving valve plate 19 is slidably connected to the vertical slide rail 20 and penetrates and cooperates with the valve strip hole.

[0037] In addition, the detachable connection structure between the support base 7 and the bracket assembly or the oven assembly may be: a locking hook is provided at the top of the support base 7, and a locking buckle capable of cooperating with the locking hook is provided at the bottom of the bracket assembly or the oven assembly.

[0039] Furthermore, the specific structure of the bracket assembly is: the bracket main body 8 includes two or more frames 21 distributed horizontally and a horizontal connecting rod 22 connecting adjacent two frames 21. A plurality of longitudinal support plates 23 distributed vertically are arranged on the opposite side walls of adjacent two frames 21 along the longitudinal direction, and the longitudinal support plates 23 of adjacent two frames 21 located on the same horizontal plane form the storage space layer. The objects placed in each storage space layer are trays 24 with their left and right ends supported on the corresponding longitudinal support plates 23. The tray 24 can adopt a mesh breathable tray structure to facilitate the smooth circulation of hot air.

[0040] Moreover, the objects placed can also be hanging rods 25 with several arranged longitudinally and their left and right ends supported on the corresponding longitudinal support plates 23.

[0041] Correspondingly, the hanging rod 25 can be directly welded to the longitudinal support plate 23. However, considering that the tray 24 or the hanging rod 25 can be placed in the storage space layer according to actual needs, the connection and cooperation structures between the tray 24 and the hanging rod 25 and the longitudinal support plate 23 are both detachable connection structures. Therefore, in this embodiment, the connection and cooperation structure between the hanging rod 25 and the longitudinal support plate 23 is: a vertical plug 26 is provided at the end of the hanging rod 25, and a connection through hole for inserting the vertical plug 26 is formed in the longitudinal support plate 23.

[0042] In order to facilitate the discharge of the grains stacked in the oven main body 9 to the outside, the oven main body 9 has a lower port, and a turning valve 27 capable of completely covering the lower port is hinged at the lower port of the oven main body 9. A driving assembly for driving the turning valve 27 to rotate up and down is provided on the oven main body 9.

[0043] Furthermore, the drive assembly can be an automated drive achieved by a motor driving a lead screw to rotate. However, in this embodiment, the drive assembly adopts a manual structure. Two flipping valves 27 are oppositely arranged to form a double-door structure. The drive assembly includes a valve support 28 connected to the oven main body 9. A drive screw 29 is rotatably connected to the valve support 28 in the vertical direction. A drive handle 30 is sleeved on the upper end of the drive screw 29. A drive seat 31 is screwed to the lower end of the drive screw 29. Both ends of the drive seat 31 are respectively hinged and cooperated with the two flipping valves 27 through drive connecting rods 32.

[0044] The above embodiments are only one of the preferred embodiments of the present invention, and do not limit the scope of implementation of the present invention. Therefore, all equivalent changes made according to the shape, structure, and principle of the present invention should be covered within the protection scope of the present invention.
