Description

Technical Field

[0001] The invention relates to the field of agricultural equipment, and more particularly to a straw recycling device. Background Art

[0002] Straw is the general term for the stems and leaves of mature crops. It usually refers to the remaining parts of wheat, rice, corn, potatoes, rapeseed, cotton, sugarcane and other crops after harvesting seeds. More than half of the products of crop photosynthesis are present in straw. Straw is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, and is a multi-purpose renewable biological resource. Straw is also a roughage. It is characterized by a high crude fiber content and contains lignin. Although lignin cellulose cannot be used by pigs and chickens, it can be absorbed and used by ruminants such as cattle and sheep.

[0003] At present, straw is generally processed by composting or direct burning. Direct burning will produce a lot of harmful gases and smoke, which has a serious impact on the air environment. If it is directly piled up, it is also very inconvenient and occupies a large space, which is not convenient for storage. How to deal with straw is a big problem for farmers after the harvest. Summary of the invention

[0004] 1. Technical issues to be solved

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide a straw recycling equipment, which first collects straw and other forage through a forage crusher, then crushes them, and transports them to the inside of a carbonization furnace by a first conveying cage. The burner sprays fire to the inside of the incineration chamber, and when the temperature of the carbonization furnace rises to 700-800 degrees Celsius, the crushed straw can be carbonized. When the burner is burning, the heat recovery pipe arranged at the upper end of the combustion furnace can transport the rising hot air into the interior of the forage crusher to preheat and dry the forage, which facilitates the forage to enter the carbonization furnace for carbonization, thereby improving the carbonization efficiency.

[0015] 3. Beneficial effects

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] (1) This scheme first collects straw and other forage through a forage crusher, then crushes them, and transports them to the interior of a carbonization furnace using a first conveying cage. The burner sprays fire into the interior of the incineration chamber. When the temperature of the carbonization furnace rises to 700-800 degrees Celsius, the crushed straw can be carbonized. When the burner is burning, a heat recovery pipe arranged at the upper end of the combustion furnace can transport the rising hot air into the interior of the forage crusher to preheat and dry the forage, making it convenient for the forage to enter the carbonization furnace for carbonization, thereby improving the carbonization efficiency. The straw forage is carbonized into charcoal sticks, which can be reused, forming a sustainable development effect and avoiding the stacking of forage straw to occupy more space.

[0018] (2) The condensed smoke is discharged into the demister. If the smoke sensor detects that there is a lot of smoke, the fan is started and the smoke is discharged into the combustion chamber through the smoke return pipe. The smoke is burned out in the combustion chamber and becomes hot air that is discharged into the forage grinder to dry the forage. If the smoke sensor detects that there is less smoke, the fan is not started and the smoke passes through the purification pipe into the plasma smoke eliminator for purification and then is discharged through the exhaust port. This will not cause air pollution, greatly increasing the environmental protection effect of the equipment and is suitable for wide promotion and application. BRIEF DESCRIPTION OF THE DRAWINGS
