Description

Technical Field

[0001] The invention relates to the technical field of forage drying equipment, and in particular to an infrared heating forage drying machine and a temperature control system. Background Art

[0002] High-quality forage is the cornerstone of the development of modern animal husbandry and the key to utilizing my country's abundant grassland resources. Scientific management is required for each link of forage planting, field management, harvesting and processing. Drying, as an important link in the post-harvest processing of forage, is of great significance to the yield, quality and storage time of forage.

[0003] At present, the most widely used forage drying at home and abroad are hot air drying equipment, solar drying equipment, high temperature and fast drying equipment, etc. The existing hot air drying equipment is mainly used for drying loose grass or bales, which is suitable for drying grass with low moisture content, but the energy consumption is high, and the drying speed of the hot air drying equipment is affected by factors such as hot air temperature, equipment size, and structure. Solar drying equipment mainly uses clean energy solar energy for drying, and has the advantages of simple structure and low equipment cost. However, since the temperature of the drying medium is greatly affected by the external environment, the temperature changes greatly, and the drying time is long, it is not suitable for short-term and large-scale drying of grass. High-temperature hot air drying equipment mainly dries cut grass with a length of less than 10 cm after harvesting by the grass harvester. With high-temperature hot air as the drying medium, it can dry grass with a high moisture content and has the advantages of fast drying rate, but the energy utilization rate of high-temperature hot air drying equipment is low, the equipment occupies a large area, and there are many supporting equipment. The cost required for drying grass is high, which limits the industrial promotion and application of grass drying.

[0004] Infrared radiation technology is a new type of pollution-free drying technology that is highly efficient, energy-saving and meets environmental protection requirements. It mainly transmits energy through electromagnetic wave radiation. In the drying of agricultural products, it mainly uses infrared rays in the long-wave band of 25 to 1000 μm to penetrate the surface of the material. When the atoms and molecules of agricultural products encounter infrared rays to absorb their energy, it will cause the particles to move more rapidly, causing the vibration energy level of the molecules to change, thereby causing the internal temperature of the material to rise. Due to the continuous evaporation of water and heat absorption, the external temperature decreases, forming a temperature gradient with high inside and low outside. According to the laws of thermodynamics, it is possible to heat the material from the inside, allowing the energy of infrared radiation to directly couple with water, thereby increasing the drying rate of the material. Due to the characteristics of low energy consumption, good drying quality and high drying efficiency, infrared drying has been widely used in the drying of agricultural products such as edible fungi, grain and oil crops, fruits and vegetables. However, the application of infrared drying technology in forage drying is still limited to experimental devices such as drying test benches, and continuous drying operations cannot be achieved, which does not meet the needs of industrial production of forage.

[0005] In view of the above technical defects, a solution is now proposed. Summary of the invention

The outer surface of the vibration hammer 23 is in active contact with the bottom end surface of the flexible material guide pad 17. ‌‌

[0042] Here’s how it works:

[0043] The forage grass to be processed is conveyed to the feed hopper 4 through the chain conveyor, and is introduced into the material guide channel 3 through the feed hopper 4. The two pressing roller shafts 9 are driven by the second motor 8 to rotate relative to each other, so that a rotating material guide groove is formed between the two pressing roller shafts 9. The forage grass to be processed is rolled into the material guide groove by the pressing roller shaft 9, and the forage grass to be processed is integrated and concentrated by the pressing roller shaft 9. At the same time, the hydraulic pump 14 drives the hydraulic push rod 15 to output driving force, driving the movable push plate 11 to reciprocate in the movable groove 10, thereby driving the two cutting knives 12 to reciprocate, and the forage grass to be processed is cut into segments by the two mutually staggered cutting knives 12;

[0044] The cut grass enters the feed channel 2, and the first motor 6 drives the threaded push rod 7 to rotate, thereby pushing the cut grass into the housing 1 and falling onto the flexible material guide pad 17. A plurality of infrared heating tubes 18 arranged in parallel are provided on both sides of the flexible material guide pad 17. The heating elements in the infrared heating tubes 18 generate infrared radiation through electric energy. Infrared radiation has a strong thermal effect and can quickly penetrate the heated object, causing the interior and surface of the object to be heated at the same time, thereby realizing efficient heating of the grass segments distributed on the flexible material guide pad 17.

[0045] The third motor 19 drives the rotating roller 20 to rotate, and the rotating roller 20 drives the vibrating hammer 23 to rotate synchronously, so that the vibrating hammer 23 is constantly in contact with the bottom of the flexible material guide pad 17, so that the flexible material guide pad 17 is constantly vibrating, thereby driving the grass segment above the flexible material guide pad 17 to vibrate accordingly, and the light grass segment is thrown upward, and the heavy grass segment is retained at the bottom and closer to the infrared heating tube 18, so that the light grass segment and the heavy grass segment are evenly heated, and the moisture content is consistent after drying;

[0046] Since the flexible material guide pad 17 is arranged to be tilted downward, the dried grass segments are guided downward along the flexible material guide pad 17 and moved to the guide channel 5, thus completing the whole process of drying the grass.

[0047] Embodiment 2:

[0048] like Figure 5 As shown, a temperature control system of an infrared heating forage dryer includes a data acquisition unit, a material analysis unit, a central management unit and a control unit;

[0049] The material acquisition unit is used to obtain relative humidity data in the feed channel 2 through a humidity sensor arranged in the feed channel 2, and simultaneously obtain the variety information of the forage grass through the operation panel on the housing 1, and send the variety information and relative humidity data of the forage grass to the material analysis unit;

[0050] Forage grass species information includes corn grass, sweet elephant grass, royal bamboo grass and ryegrass;

[0051] The material analysis unit is used to obtain and process the variety information and relative humidity data of the forage grass, obtain the leaf size data and moisture content data of the forage grass from the network database according to the variety information of the forage grass, and calculate the drying influence coefficient of the forage grass based on the relative humidity data, and then calculate the drying efficiency coefficient of the forage grass and send it to the central management unit;

[0052] The specific process of calculating the drying efficiency coefficient of forage is as follows:

[0053] S1, obtaining blade size data and water content data W% of forage grass, wherein the blade size data of forage grass includes blade width data B and blade thickness data T;

[0054] S2. Obtain the relative humidity data RH and calculate the drying influence coefficient ki of the grass according to the following formula: , where Si is the cross-sectional area of ​​the material guiding channel 3, H is the height of the material guiding channel 3, and e1 is a preset proportional coefficient;

[0055] S3. Calculate the drying efficiency coefficient Ei of the grass according to the following formula: , where e2 and e3 are preset weight coefficients, where L is the length data of the grass segment, and the L value is determined according to the output frequency of the hydraulic pump 14.

[0056] The central management unit includes an efficiency analysis module and a parameter setting module. The efficiency analysis module is configured with a primary heating mode, a secondary heating mode and a tertiary heating mode based on the heating efficiency of the infrared heating tube 18. After obtaining the drying efficiency coefficient, the corresponding heating mode is matched according to the coefficient value of the efficiency drying coefficient, and the selection of the heating mode is sent to the parameter setting module. The parameter setting module is configured with corresponding parameter data for the current of the infrared heating tube 18 and the speed of the third motor 19 according to the primary heating mode, the secondary heating mode and the tertiary heating mode, and the corresponding parameter data is output to the control unit according to the selection of the heating mode;

[0057] The drying efficiency coefficient Ei is used to indicate the drying temperature and turning frequency required for the grass. The larger the drying efficiency coefficient Ei is, the higher the drying temperature of the grass is and the higher the turning frequency is. On the contrary, the smaller the drying efficiency coefficient Ei is, the lower the drying temperature of the grass is and the lower the turning frequency is. Therefore, the drying temperature corresponding to the first-level heating mode, the second-level heating mode and the third-level heating mode increases step by step, and the turning frequency also increases step by step.

[0058] The control unit is used to obtain parameter data and then automatically adjust the current of the infrared heating tube 18 and the rotation speed of the third motor 19, so that the grass in the casing 1 is dried efficiently.

[0059] The present invention obtains leaf size data and water content data of forage grass from a network database according to the variety information of the forage grass, calculates the drying influence coefficient of the forage grass based on the relative humidity data, and then calculates the drying efficiency coefficient of the forage grass, matches the corresponding heating mode according to the coefficient value of the efficiency drying coefficient, obtains parameter data, and then automatically adjusts the current of the infrared heating tube 18 and the speed of the third motor 19, so that the forage grass in the casing 1 is efficiently dried.

[0060] The size of the interval and threshold is set to facilitate comparison. The size of the threshold depends on the amount of sample data and the number of bases set by technical personnel in this field for each group of sample data; as long as it does not affect the proportional relationship between the parameter and the quantized value.

The formula is a formula obtained by collecting a large amount of data and performing software simulation to obtain the most recent real situation. The preset parameters in the formula are set by technicians in this field according to actual conditions.
