Description

Portable High Temperature Shredder

technical field

The invention belongs to the field of office supplies and relates to a portable high-temperature paper shredding machine.

Background technique

The paper shredders in the prior art mainly shred the paper through a pair of hobs. The shredding efficiency is low, and only a small amount of paper can be shredded each time, and it takes a long time to destroy a large amount of paper materials in a short time. , and the noise is large, and limited by the power supply, generally only suitable for 220V mains, so it is not suitable for carrying. In addition, the paper is shredded and fragmented. In a sense, its confidentiality is not good, because for paper documents As far as the data become fragmented, it is a waste, not a complete destruction in the true sense. Especially for non-paper documents such as tapes, CDs, etc., it is difficult to waste them with the shredders in the prior art. cannot be completely destroyed.

Contents of the invention

Technical issues solved:

Provide a high-temperature paper destroying machine, which can overcome the deficiencies in the prior art. After using high-temperature burning and baking to carbonize and coke the paper, it is then crushed with a shredder. Therefore, it is not only a waste of paper documents , and can be completely destroyed, high efficiency, good effect, no noise, not only can be used to destroy paper, but also can be used to destroy non-paper information materials such as tapes, CDs, AC and DC power supply, easy to use, easy to carry , and can be used as a safe for information materials, and the stored materials can be quickly destroyed in an emergency.

The technical solution adopted:

Portable high-temperature paper shredding machine, including a high-temperature heat-insulated box shell with a cover and a side door, a paper shredding mechanism and a circuit control system. After being burnt and roasted at high temperature by a high-temperature paper destroyer to be charred or burnt and embrittled, it is then pulverized by a pulverizer;

The structure of the high-temperature paper destroyer is that it has a heating tube with a 220V AC power supply and a "W"-shaped plane body. There are three "U"-shaped gaps on the plane body. Each heating tube is placed vertically, and the plane of each heating tube The main bodies are parallel to each other, equidistant and fixed in a single row on the base connected to the power supply. The base is detachably mounted on the rear wall of the box shell. The supporting board is installed on the rear and front wall boards of the box shell, and the information materials are vertically placed in the gap between the heating tubes and supported on the horizontal supporting board. The heating tubes are energized one by one, the relay is started and Heating at regular intervals, generating and releasing high temperature, burning, roasting, and carbonizing or scorching and embrittlement of information;

The structure of the shredder is that it has a power drive mechanism. The structure is that the vertical shaft of the motor installed on the bottom plate of the box shell passes through the heat shield and is equipped with gears. The gears are located under the horizontal supporting plate. The periphery is fixedly connected with the inner wall of the box shell. The heat shield divides the inner cavity of the box shell into an upper high-temperature working area and a lower low-temperature control area. The left shredded cardboard is fixed together, and the other one is fixedly connected with the right shredded board by its right end; the left and right shredded boards are matched with each other and are respectively located outside the left and right ends of the single row of heating pipes.
