Description

Technical Field

[0001] The present invention relates to the technical field of equipment for making fertilizer from household waste, and in particular to a kitchen waste composting device based on freezing, and the specific international patent classification number that may be involved is C09F9 / 02. Background Art

[0002] At present, with the improvement of environmental awareness, kitchen waste composters have begun to enter the C-end user market. Existing kitchen waste composters use a low-speed, high-torque crushing device driven by a reduction motor to crush the garbage, and at the same time heat and dry the garbage, and finally crush the kitchen waste, dry it, and oxidize it into fertilizer. This way of crushing garbage has a large enough torque to crush hard bones or plastic garbage, but it is easy to cause entanglement and is not easy to crush fiber-containing garbage. In addition, due to the need for high torque, the speed of the crushing arm is very low, which takes a long time and the crushed particles are large in size. The smaller the particle size, the more conducive it is for kitchen waste fertilizer to be decomposed by microorganisms in the soil and converted into small molecular nutrients that can be absorbed by plants. In the field of mechanical processing, since some metals cannot be fixed and adsorbed by the magnetic base of the lathe, a frozen base is used. It sprays water on the base, and then freezes the parts to be processed to the base through a cooling device. It is an efficient fixing method. The present invention aims to utilize the freezing principle to freeze the kitchen waste first and then grind it layer by layer from top to bottom. The waste will not escape or get entangled during the grinding process, and freezing will cause the kitchen waste to become brittle, so the grinding efficiency is higher and the particle size is finer. Summary of the invention

[0019] When the motor drive mechanism drives the grinding disc 3 to rotate, due to the deadweight of the grinding disc 3, as the frozen garbage is ground, the grinding disc 3 will slowly drop. The cross section of the guide rod 4 can be set to a polygonal shape, that is, it is linked with the power output end of the motor drive mechanism and is axially slidably connected thereto. The motor drive mechanism can be composed of a drive motor 14, a reduction box 15, and a power output end with a transmission hole 16.

[0020] The kitchen waste put into the grinding cylinder 1 can be dry waste or wet waste. In order to freeze it firmly, water can be added to the grinding cylinder 1. After the cooling device works, the kitchen waste will be frozen and brittle in water or under highly humid conditions. The grinding end 17 of the grinding disc 3 can be set as a consumable that can be disassembled and replaced. The greater the roughness of the grinding end, the larger the particle size after grinding, and vice versa.

[0022] The soft auger blade 6 is frictionally matched with the inner wall of the grinding cylinder 1.

[0028] As an optimization of the above embodiment, travel switches 11 are installed at the positions of the grinding cylinder 1 that match the highest and lowest travels of the guide rod 4; the travel switch 11 located at the lower position is used to give a signal for the motor drive mechanism to rotate in the opposite direction when the grinding disc 3 reaches the bottom surface of the grinding cylinder 1; the travel switch 11 located at the higher position is used to give a signal for the motor drive mechanism to stop rotating when the grinding disc 3 reaches the highest position from bottom to top.
