Description

New intelligent biomass pellet fuel pelletizing equipment

technical field

The utility model relates to biomass energy equipment, in particular to a novel intelligent biomass particle fuel granulation equipment.

Background technique

Biomass is a storage form of solar energy. Various organisms produced by photosynthesis directly or indirectly from land, water and air, that is, all living organic substances that can grow are collectively referred to as biomass. Useless biomass and biomass waste, such as straw, straw, rice husk, peanut husk, corn cob, camellia husk, cottonseed husk, etc., and "three leftovers" can be used to generate energy, that is, biomass energy.

The research and development of bio-energy technology has become one of the major hot topics in the world. Many countries have formulated corresponding development and research plans, such as the Sunshine Project in Japan, the Green Energy Project in India, and the Energy Farm in the United States. Among them, the development and utilization of bio-energy occupy a considerable share. Taking the United States, Sweden and Austria as examples, the application scale of bioenergy accounts for 4%, 16% and 10% of the country's primary energy consumption respectively. China also attaches great importance to the development and utilization of bio-energy. Since the 1980s, the Chinese government has always listed the research and application of biomass energy utilization technology as a key scientific and technological project, and carried out research and development of new technologies for biomass energy utilization, which has further improved biomass energy technology.

Biomass fuel molding technology is an important aspect of bioenergy technology research and development. Biomass fuel manufacturing equipment mainly includes biomass fuel briquetting equipment and biomass fuel pelletizing equipment. The main equipment plus crushing equipment, drying equipment, packaging equipment and other auxiliary equipment constitute the entire complete equipment system. Because granular biomass fuel has the advantages of convenient transportation and full combustion compared with briquetting, most companies use biomass pellet fuel pelletizing equipment as the main engine.

At present, most of the production of biomass pellet fuel is done by feed ring die pellet mill instead, which causes a lot of problems. Due to the different characteristics of feed pellets and sawdust pellets, the pressure of the feed pellet mill is relatively small, the opening rate of the ring die is relatively high, and the stainless steel molds used are relatively expensive, resulting in many broken molds when manufacturing biomass pellet fuel, and the main shaft of the host machine has It is easy to break, and the production cost is very expensive. About one-third of the cost is equipment maintenance and spare parts procurement costs, which is much higher than the 5% of feed.

In order to adapt to the characteristics of wood pellets, most of the feed pellet mills are modified through the following methods. One is to strengthen the structure of the original feed pellet mill, such as replacing the motor with a higher power, the main shaft, and the rigid design of the body. The feed ring die is changed from stainless steel to alloy steel, which reduces the cost of mold manufacturing and the loss when it breaks. However, since the whole mechanism is still applied to the feed pellet machine, there is no overall mechanism improvement for wood pellets, and there are still the following problems: because the pressure of the wood chips is too high, the main components such as the main shaft and the ring die are replaced frequently, and the cost is very high. For a new machine, the main shaft will need to be replaced in the second year, about 20,000 yuan each, and will need to be replaced once or twice a year after that; high power consumption; low unit output (most models are less than 1 ton/hour), etc. question.

Another automatic biomass fuel granulation equipment is disclosed by CN201988365U. The granulator is fixed with a roller shaft under the silo, and two tapered rollers are fixed at both ends of the roller shaft. The tapered flat template has a plurality of die holes on the slope of the tapered flat template, and the tapered flat template is fixed on the output shaft of the motor reducer. After the material is fed into the granulator, the powdered material falls on the conical flat plate, and the conical flat plate rotates in the horizontal direction under the drive of the motor reducer, driving the conical roller to drive on the conical flat plate. According to different materials and the degree of wear between the tapered roller and the tapered flat plate, the gap between the tapered roller and the tapered flat plate can be adjusted through the adjustment screws at both ends of the roller shaft. The material enters the tapered flat plate under the extrusion of the tapered roller. The die hole of the formwork; when the extruded continuous material reaches the cutter, it is cut into particles by the cutter. However, since the conical flat plate is fixed on the output shaft of the motor reducer, when the high extrusion force of the tapered rollers is unbalanced, the force on the conical flat plate is likely to be uneven, and the conical flat plate shakes, thereby damaging the main shaft and even the motor.

Utility model content

In order to overcome the defects of the prior art, the utility model provides a novel intelligent biomass pellet fuel pelletizing equipment.

The novel intelligent biomass particle fuel granulation equipment of the utility model includes a main shaft, a transmission disc, a ring die, a pressure roller and a control module, and is characterized in that the transmission disc is arranged on the main shaft, and the ring die and the press roller are arranged on the transmission disc. The pressure roller shaft is placed on the machine cover, and the pressure roller is close to the inner wall of the ring die; the control module is connected to the power switch and the motor detection sensor installed at the motor end to detect the motor load, and is used to process the motor collected by the motor detection sensor. load data, and issue instructions to control the power switch action according to the processing results.

In the prior art, the structure obtained by reforming the feed ring die granulator is that the main shaft drives the pressure roller, and there is an empty shaft outside the main shaft, which is used to drive the transmission disc. The ring die is installed on the transmission disc, and the motor drives the empty shaft to rotate. , the ring die is active, and the pressure roller is driven. Because there is a gap between the main shaft and the hollow shaft, and the extrusion force of wood pellets is much greater than that of feed pellets, and there are more impurities inside, it is easier to press foreign objects, so it often shakes, resulting in excessive pressure on the main shaft at an instant, until it breaks. The utility model adopts a completely different structure, the pressure roller is separated from the main shaft, and the ring die and the pressure die are separated and installed. Without the empty shaft, the main shaft directly drives the ring die to rotate. The ring die is the active one and the pressure roller is the driven one. But because there is no gap in the main shaft, it can withstand greater pressure and is not easy to break. Moreover, the motor detection sensor can detect the load of the motor and sense the instantaneous pressure of the main shaft during the pelletizing process of biomass pellet fuel. Stop rotation to better protect the spindle.

The technical scheme of the utility model solves the problems of the prior art and realizes the purpose of the utility model.

Further improvements to the above technical solutions or selections and equivalent replacements of technical features include:

In order to make the installation and operation of the pressing roller stable and stable, the two ends of the pressing roller shaft are placed on the machine cover and the assembly gland respectively. Since the machine cover and assembly gland are located at both ends of the ring die, the position of the pressure roller in the ring die can be more determined and run stably.

In order to protect the ring die and make the rotation of the ring die more stable, a wear-resistant sleeve is set between the transmission disc and the ring die.

Using different raw materials and producing products of different specifications, in order to extrude the powder more smoothly, appropriate pressure is required, so it is necessary to adjust the distance between the pressing roller and the ring die. Therefore, the utility model is set for Roller adjustment device for adjusting the position of the roller shaft.

Preferably, the pressure roller adjustment device is arranged outside the machine cover for easy operation.

As a way to facilitate the adjustment of the positional relationship between the pressure roller and the ring die, it is very simple and effective to choose the eccentric axis of the pressure roller.

Through experiments, the production of biomass pellet fuel with sawdust trial machine has been successful. The biomass particle fuel granulation equipment of the utility model greatly increases machine stability, greatly reduces maintenance time, the main shaft can withstand greater pressure, and the feeding speed can be increased. The output per hour can be 1.5-2 times that of traditional machinery; the main shaft has not been replaced in three years, the consumption of wearing parts such as ring dies has been reduced by more than 20%, and the power consumption can also be reduced by about 10%.
