Description

Charcoal rod making machine

technical field

The utility model relates to equipment for producing charcoal, in particular to a charcoal rod making machine.

Background technique

With the rapid development of the national economy, the demand for charcoal in my country is increasing year by year. According to expert estimates, the annual demand for charcoal in the domestic chemical and metallurgical industries is 7 million tons, and the annual demand for charcoal in the food industry is about 5 million tons. And the machine-made sticks needed by the district heating boilers in the unit area are just as much as 4 million tons as fuel. In recent years, the Chinese government has put ecological environment protection and construction on the agenda. During the "Ninth Five-Year Plan" period, the natural forest protection project has been implemented, and the use of natural forests to produce charcoal is strictly restricted. Mechanism charcoal using renewable energy has broad market prospects. The advantages of this kind of mechanism charcoal are complete combustion, high calorific value, and no harmful gases such as sulfur dioxide in the exhaust gas, which has the effect of environmental protection and energy saving. The main raw materials of machine-made charcoal are crop straw, sawdust, rice husk and some rural renewable fuels. my country is a large agricultural country with a large amount of renewable energy. Many resources are wasted due to unreasonable utilization. Such as sawdust, straw, cotton stalks, etc. If they are reused and made into machine-made charcoal, it will be a considerable source of environmentally friendly energy. The production of machine-made charcoal has the following characteristics: First, the investment is small. Generally, it only needs about 100,000 yuan to build a machine-made charcoal factory, which is suitable for the investment of rural individuals. Second, the return is fast. For manufacturers with a scale of 100,000 yuan, according to the domestic and international market prices (the domestic market price is generally 1700-2500 yuan/ton, and the international market price is generally 2800-4200 yuan/ton.) One year In addition to the input, the production volume can make a net profit of 80,000 to 100,000 yuan. Third, this kind of charcoal is environmentally friendly and energy-saving. The current market demand is in short supply, and the investment risk is small. The production of charcoal requires corresponding machinery and equipment. From this point of view, the most critical rod making machine for mechanism charcoal also has broad market prospects. At present, the main component of the domestically produced charcoal rod making machine - the screw propeller is very easy to wear, the maintenance is very frequent, and the maintenance cost is quite high. It costs almost 40 yuan for the maintenance cost of producing one ton of charcoal.

Contents of the invention

The purpose of the utility model is to improve the shortcomings and problems existing in the background technology, and provide an energy-saving, high-efficiency, low-cost, fully automatic control, and easy-to-operate charcoal rod making machine.

The frame and the motor, transmission mechanism, speed change mechanism, feeding mechanism, screw propulsion mechanism, heating mechanism, discharge mechanism and electric control cabinet arranged on the frame; wherein the motor is pivotally connected to the transmission mechanism, the speed change mechanism, and the symmetrically arranged The screw propulsion mechanism, the discharge mechanism is connected to the end of the screw propulsion mechanism, the heating mechanism is arranged on the discharge mechanism, and the feeding mechanism is arranged above the screw propulsion mechanism.

After more than one year of research and testing, the utility model adopts the Cr12MoV material for the propeller, and its service life is increased by 4-5 times, the maintenance cost is reduced, and the economic benefit is improved. It will save 35,000 to 40,000 yuan in maintenance costs, which means that each set of equipment will increase the net profit of 35,000 to 40,000 yuan. In addition, the traditional charcoal rod making machine is changed from a single discharge barrel to a double discharge barrel, and the belt and gear are used for two-stage reduction transmission. When the motor power is increased by 15.9%, the output is doubled. Improve the efficiency of the equipment. Thus this new type of charcoal rod making machine has considerable economic value.
