Detailed Description

For the purpose of explaining the technical solution disclosed in the present invention in detail, the following description is further made with reference to the accompanying drawings and specific embodiments.

The utility model provides heat energy recovery type drying equipment which is mainly suitable for flower dehydration and drying processes of chrysanthemum tea and is also suitable for dehydration treatment of other plants.

To flower stoving preparation demand, prior art includes kiln heating intensification dehydration and adopts drying equipment, but according to the practical application discovery, there are the circumstances such as inhomogeneous of being heated in the current drying equipment, its main reason lies in that the hot gas flow diffusion mode leads to, this factor root cause lies in admitting air, the air flue, it is unreasonable to give vent to anger isotructure, in practice need reduce the temperature, extension stoving time etc. are overcome, it still needs to point out simultaneously, current drying equipment has a large amount of hot gas and arranges the phenomenon outward, lead to phenomenon such as indoor temperature too high, there is the great condition of energy consumption.

Referring to fig. 1 and 2, the heat energy recovery type drying apparatus of the present invention adopts a cabinet design in an overall structure, and includes a cabinet 1, a control room is provided in a middle portion of the cabinet 1 for installing a drying main machine 2, and the drying main machine 2 provides hot air for an air compressing and heating apparatus in the prior art. According to the utility model, a modularized installation mode is adopted to improve the finishing degree of the whole machine, and a control panel is arranged on the outer surface of the machine cabinet 1 for operation and control. The main drying machine 2 sucks air from a fresh air inlet 4 arranged at the top, then enters an air compressor to be pressurized and heated, and then is discharged downwards through a fan structure, and with continuous hot air removal, the pressure in a chamber at the bottom of the main drying machine 2 is increased, and then the hot air is diffused to two sides and the bottom. Located the drying chamber of drying host 2 both sides, figure 1 includes left drying chamber 301 and right drying chamber 302, and in the drying chamber, be close to drying host 2 this side bottom and be equipped with air intake 8, hot-air enters into the bottom of drying chamber by air intake 8, then according to the principle that hot-air upwards spreads to under the pressure effect of constantly carrying hot-air, the steam molecule can constantly upwards move. In the process of hot gas molecule movement, because the hot gas molecule meets the upper-layer low-temperature molecules, heat exchange can be carried out, the temperature is reduced, and further the condition of uneven heating exists, in order to avoid the condition, the bottom of the cabinet 1 is provided with the gas channel 9, the heat generated by the drying main machine 2 can be supplied to the air outlet 10 in the middle of the side wall through the gas channel 9 and is discharged from the air outlet 10, in order to further improve the temperature control and the heating effect, the air outlet 10 is provided with the inclined baffle plate, even if the opening of the inclined baffle plate is upward, the hot air tends to move upward, the hot air is further promoted to move upward, the pressure is enhanced and changed by combining the control of the drying main machine 2, namely, the hot air forms ascending air flow in the drying chamber. Reach the top of drying chamber, because of the drying chamber top does not establish the shrouding, the drying chamber top is equipped with the return air inlet and accesss to stoving host computer 2, and stoving host computer 2 is equipped with the demand that the air inlet was admitted air, and hot-air also can carry out quadratic compression heating along with the cold air that is inhaleed by fresh air inlet 4 enters into stoving host computer 2, constitutes a circulating air current in the drying chamber from this. It is noted that, relatively speaking, the temperature of the air entering the fresh air inlet 4 is relatively low, and the hot air rising to the top is more easily reused under the action of the air intake suction force of the drying main machine 2.

With reference to the airflow path shown in fig. 2, in the bottom of the cabinet 1 in the above embodiment, the sidewall of the drying chamber is only controlled to be vented through the opening, and the other positions of the sidewall gap of the cabinet 1 are sealed by sealing plates. Because different plants are dried under different drying conditions and requirements, through holes can be formed in the inner wall of an interlayer formed by the air channel 9 on the side wall of the cabinet 1, the drying chamber and the cabinet, namely, hot air flowing through the air channel 9 can be transversely diffused into the drying chamber through the through holes.

More specifically, the drying chamber according to the present invention is provided with a door 7 alone. Be equipped with tray support piece 7 on the both sides wall in the drying chamber for place the sieve dish, the sieve dish is used for holding plants such as flowers, holds for the drawer type through tray support piece 7 on the both sides wall, also directly pushes away the drying chamber after putting including adopting to hold the frame. The sieve tray is a porous reticular structure and is arranged in a layer-by-layer stacking mode.
