Abstract

The present invention relates to a crusher composed of three-axis circular (saw) blades, wherein the shaft of the crushing blade can move elastically up and down when foreign substances mixed with combustible waste are introduced. More preferably, when combustible waste, such as household waste, industrial waste, landfill sorting waste, and marine waste including fishing nets and metals mixed in ropes, is sorted and fed through the inlet of the crushing device and compressed into the crushing housing by a piston of a cylinder, and then crushed by the crushing blades formed by three-axis circular (saw) blades installed at the top and bottom, the rotating shaft equipped with the crushing blades is configured to move up and down due to the pressure of the foreign substances to prevent the crushing and discharge of foreign substances (metal, stones, substances that place a load on the motor) remaining in the combustible waste from placing a load on the crushing blades, thereby enabling discharge. Additionally, by installing a height adjustment plate to allow height adjustment when the upper circular saw blade wears out, the expensive circular saw blades can be replaced The present invention relates to a crusher composed of a three-axis circular saw that allows the crushing blade axis to move elastically up and down when foreign matter mixed in combustible waste is introduced, so as to enable economical use and prevent damage to the crushing blade, and to enable continuous crushing without stopping work.

Description

Combustible waste wave crusher using the triaxial circular (saw) blade The present invention relates to a combustible waste crushing device using a three-axis circular (saw) blade, wherein the shaft of the crushing blade can move elastically up and down when foreign substances mixed with combustible waste are introduced. More preferably, when combustible waste, such as household waste, industrial waste, landfill sorting waste, and marine waste including fishing nets and metals mixed in ropes, is introduced through the inlet of the crushing device and then fed into the crushing housing by a piston of a cylinder and crushed by the crushing (saw) blades installed at the top and bottom, the device is configured such that the rotating shaft at the bottom, equipped with the crushing (saw) blade, moves downward due to the pressure of foreign substances (metal, stones, substances that place a load on the motor) remaining in the combustible waste to prevent crushing and discharge, thereby preventing the crushing (saw) blade from being overloaded, and thus preventing damage to the crushing (saw) blade and enabling continuous crushing without stopping operations. This relates to a combustible waste crushing device using a 3-axis circular (saw) blade. Generally, methods for pre-treating combustible waste such as waste vinyl used for agricultural purposes in rural areas, combustible waste discarded from households and industrial sites, combustible waste sorted from landfill waste, fishing nets, and hops include, first, burying the combustible waste underground; second, incinerating the combustible waste; and third, melting the combustible waste for recycling. The first method described above has the advantage of disposing of combustible waste at the lowest cost, but it has the disadvantage of acting as a factor that contaminates the soil because it takes a very long time for ordinary combustible waste to naturally decompose and be absorbed. In addition, while the second method allows for the fastest disposal of combustible waste, it has the disadvantage of causing air pollution and incurring high processing costs because various pollutants are released into the atmosphere during the incineration process. Considering these issues, methods for recycling combustible waste are being utilized recently. The government has established the principle of waste reuse, recycling, incineration, and landfilling, and is actively supporting the recycling of combustible waste. As described above, in order to recycle combustible waste, it is first cut and crushed using a shredder. The shredder is equipment that performs a process to make the size of the shredded waste relatively uniform by crushing the waste to make it smaller than its original form. In most cases, the volume is reduced after crushing, and it is commonly used to increase the efficiency of recycling by reducing the volume of the material and standardizing the waste. The process for crushing and recycling combustible waste involves a pretreatment process for the collected combustible waste. This pretreatment process is divided into a sorting process to remove soil, stones, and metal materials, a cutting (crushing) process to cut the combustible waste into sizes suitable for recycling, and a drying process in a drying oven to remove moisture contained in the combustible waste. Regarding the process of cutting combustible waste for drying in the above-mentioned drying oven, Korean Registered Patent No. 10-0740192, titled "Hydraulic Cutting Device for Industrial Waste," was disclosed; however, since the above configuration cuts combustible waste only vertically using a vertically moving blade, its productivity is low. Furthermore, because the combustible waste is cut into long horizontal lengths without uniform length, air pressure is generated in the combustible waste when fed into the drying oven's hopper, causing difficulties in feeding and requiring manual feeding. In other words, since combustible waste is cut only vertically, the cutting specifications are inconsistent during vertical cutting, and furthermore, combustible waste gets stuck between the vertical moving cutting (saw) blade and the fixed blade, resulting in the cutting work not being completed perfectly and the work being interrupted due to the load being placed on the cutting (saw) blade, thus failing to achieve work continuity and causing a decrease in work efficiency. In addition, the "Waste Vinyl Cutter" disclosed in Korean Registered Patent No. 10-0922615 was introduced. However, although the configuration involves installing multiple fixed blades vertically and then pushing combustible waste with a compressor to cut it, this also had the problem of consuming a large amount of energy. Furthermore, since the combustible waste cut between the fixed blades had inconsistent cutting dimensions and was cut only into long vertical strips, air pressure was generated in the combustible waste when fed into the dr
