Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical engineering, and in particular relates to a rapeseed drying device. Background Art

[0002] In the whole process from planting to finished product of rapeseed, the most important problem is the drying problem after rapeseed is harvested. Due to weather or poor performance, most drying equipment has the following problems: if high temperature is used in the drying process, it is easy to cause rapeseed oil spill; if low temperature is used in the drying process, the drying time is long and the drying efficiency is low. Therefore, a reasonable drying temperature should be adjusted in the process of rapeseed drying. If the temperature is too low, precipitation will be slow; if the temperature is too high, it will cause oil spillage, which is not conducive to drying and may also cause fire. At present, typical dryers on the market mainly include drum dryers, fluidized bed dryers, etc. Most dryers use hot air as the drying medium. Hot air drying is instantaneous drying with relatively high temperature, which can easily cause uneven thermal stress on the internal structure of rapeseed, resulting in bursting. Therefore, the drying effect is often poor, and insufficient drying can easily lead to moisture absorption, sprouting, mildew and other problems. Rapeseed has a strong hydrophilic ability, so rapeseed drying equipment should have good sealing performance to ensure the air humidity inside the drying equipment. The existing technology mentions reducing the pressure through vacuum drying technology to further reduce the temperature required for rapeseed drying, thereby ensuring drying efficiency while improving drying quality. However, most rapeseed vacuum dryers have complex structures and require external power supplies, which is not conducive to energy saving and has limited actual application scenarios.

The utility model can realize independent energy supply without the need for an external power supply, so it has high flexibility, is easy to move, and has a wide range of application scenarios.

Preferably, the light intensity value detected by the photosensitive sensors 113 can be set accurately to the unit digit, for example: the light intensity values ​​detected by the photosensitive sensors on the sides are all 113, thereby concluding that the light intensity values ​​detected by the photosensitive sensors on the sides are basically consistent, so that the sunlight can be vertically incident on the Fresnel lens 111 in the solar frequency-divided electric heat and power cogeneration module 1 in real time.

[0082] The above scheme specifically includes the following steps:

[0083] Step S1: Fig.12 , Fig.13As shown, when working, when all the photosensors 113 detect that the light intensity reaches the preset value, the control device controls the a port of the first electromagnetic reversing valve 281 to be connected with the b port, the a port of the second electromagnetic reversing valve 282 to be connected with the c port, the a port of the third electromagnetic reversing valve 56 to be connected with the c port, and the circulation pump 25 is energized.

At this time, the fifth connecting pipeline 245 and the third connecting pipeline 243 are in a disconnected state, the sixth connecting pipeline 246, the fourth connecting pipeline 244, and the third connecting pipeline 243 are in a connected state, and the sunlight is converted into electrical energy and light energy through the solar frequency division electric heat and power generation module 1, and the electrical energy is stored in the solar cell panel 16, and the solar cell The board 16 supplies power to the control device, the vacuum low-temperature drying module 5 and the driving steering gear 13. The heat energy is transmitted to the heat storage buffer element 29 through the heat conduction of the copper tube 21 built into the concave lens. The heat storage buffer element 29 provides heat for the pipeline circulation system 2. The control device turns on the electric heating belt. The temperature sensor in the vacuum low-temperature drying module 5 transmits the detected temperature to the control device in real time. The control device compares the temperature value with the preset value, thereby controlling the heating temperature of the electric heating belt, so that the temperature in the vacuum box 51 of the vacuum low-temperature drying module 5 is kept constant within the preset range, so that the temperature in the vacuum box 51 is always within the optimal rapeseed drying temperature range;

[0086] Step S4: When not working, when all the photosensors 113 detect that the light intensity does not reach the preset value, the first electromagnetic reversing valve 281, the second electromagnetic reversing valve 282, the third electromagnetic reversing valve 56, and the circulation pump 25 are powered off.
