Description

An all-in-one machine for dehydrating and crushing fuel of banana pseudostem

technical field

The utility model relates to a banana pseudostem processing equipment, in particular to a banana pseudostem dehydration, pulverization and fuel forming integrated machine.

Background technique

Banana belongs to the Musa plant of the Musa family and is a common plant in subtropical regions of my country. Its plant is a large herb, and a 3-6 meter long pseudo-stem is formed from the rhizome to the lower part of the leaf sheath. There are many varieties of bananas, and the length and cross-sectional diameter of the pseudo-stems of different types of bananas will vary. Bananas reproduce mainly by root transplantation.

The banana industry is a pillar industry in the subtropical region of my country. The banana production areas in my country are mainly distributed in Guangdong, Guangxi, Fujian, Taiwan, Yunnan and Hainan. At present, the banana industry has basically realized the mechanized production and treatment of important production links such as plowing, land preparation, planting, irrigation, fertilization, plant protection, and harvesting. However, the follow-up mechanized treatment of bulky banana straw is still in the research and exploration stage, which has restricted The large-scale development of the banana industry and its sideline business.

Banana straw (false stems and leaves) are the main by-products of bananas and are of considerable value for recycling. However, there are still few mature technologies for the resource utilization of banana straw in China, which has been perplexing the development of the banana industry and its by-products. At present, the common way to deal with banana straws is to manually cut and excavate the bananas after harvesting, and move the straws to the edge of the field for stacking or transporting them away for burning. The utilization rate of cultivated land seriously pollutes the ecological environment inside and outside the banana orchard. Therefore, it is of great practical significance to study a device that effectively recycles banana stalks.

The two rollers rotate and bring the false stem into the dehydration guide rail at the same time, and at the same time crush the false stem to a certain extent, and the water that comes out flows into the sump below the dehydration area. Then the pseudostems are successively dehydrated under the action of rolling and conveying by the second, third, fourth, ... stage rollers. The flat pseudostem obtained after rolling and dehydration is sent to the hob cutting mechanism with the assistance of the feeding wheel. The pseudostem is cut into sections, and the sectioned pseudostems are thrown into the kneading and crushing mechanism. The two kneading shafts rotate relative to each other, driving the rotating hammer on the shaft to crush and strike the section-shaped pseudostem, tearing the epidermis and stem nodes of the pseudostem cut by the blade. It is squeezed and rubbed in the middle to form soft filaments and achieve secondary crushing. In addition, the kneading hammers distributed in a spiral shape make the crushed filiform pseudostems be transmitted from the front end of the kneading and crushing mechanism to the rear end, and enter the extrusion chamber of the screw extrusion molding mechanism through the collecting hopper. The filiform pseudostem advances axially under the push of the rotating blades on the forming extrusion screw. During the advancing process, the filiform pseudostem forms a huge extrusion force under the action of the gradually changing pitch screw, making the filiform pseudostem Under the action of external force, it is continuously compressed and sent to the stirring device. A small amount of water generated during the screw extrusion and mixing process is filtered through the filter screen, and then flows from the drain pipe to the sump and is treated by the drainage system before being discharged. The pseudostem after stirring and secondary dehydration is extruded in a columnar shape from the discharge hole of the screw extrusion molding mechanism, and the extruded columnar material is cut into small cylindrical material blocks under the action of the shearing device.

The beneficial effect of the utility model is that the banana pseudostems can be dehydrated, crushed, and extruded to be organically combined, and the complete banana pseudostems can be completely processed at one time, which not only solves the problem that a large number of banana pseudostems occupy a large area , pollute the environment and other intractable problems, and provide energy and fuel, and also automate the process of banana pseudostem processing and production as fuel, reduce labor costs and improve production efficiency. Simultaneously, the volume of the pseudo-stem of the banana becomes smaller, which is convenient for transportation.
