Description
Technical Field
The invention relates to the field of rice polishing equipment, in particular to a large belly polishing shaft with a self-suction effect.
Background
As the prior art, the rice polishing machine is widely applied to the rice processing industry at present and is used for improving the appearance and the quality guarantee period of rice.
The core part of the rice polishing machine is a polishing roller, and the mainstream rice polishing rollers on the market at present have two types: one is a sleeve roller type, namely, a polishing roller and a transmission shaft are manufactured respectively, and then the polishing roller is sleeved on the transmission shaft; the other is to make the polishing roller and the transmission shaft into a whole; in the polishing roller, the main shaft is hollow, air needs to be sucked from the main shaft hole and then is sprayed out from the air spraying hole on the polishing roller, so that materials in the polishing chamber are suspended and supported by air flow, and ground rice flour in the polishing process is taken away by the air flow; the air flow also carries a polishing agent (purified water) for auxiliary polishing into the polishing chamber to mix with the rice.
However, due to the limitation of factors such as processing means and polishing process requirements, the existing common polishing roller or polishing shaft has the following defects:
1. mechanical assembly limitation: the size of the shaft hole of the polishing shaft with the same model is limited by a bearing or a driving belt wheel, so that the size of the shaft hole cannot be too large; this results in a limitation in the amount of air flow drawn into the polishing chamber.
2. During the rice polishing process, a large amount of heat is generated due to mutual friction of rice grains, the heat needs to be taken away by air flow assistance, otherwise, during the processing process, the rice temperature is too high, and the quality of a rice finished product is affected; therefore, it is desirable to maximize the flow of air into the polishing chamber; because the size of the shaft hole is limited, the performance of the induced draft fan can be improved only by improving the airflow to increase the air quantity; therefore, the air speed of the air flow entering the polishing chamber is greatly increased, but the air speed is too high, so that the air resistance of the system is increased and the energy consumption is increased, and on the other hand, the high air speed can increase the loss of the rice processing process, increase the broken rice rate, increase the flour yield and the like, and is not beneficial to the society and the economy.
3. In order to increase the area of an air inlet, the polishing shaft and the polishing roller are integrated, so that the air inlet area of the polishing chamber can be effectively increased, and the trouble of the problems is well reduced; however, there is still a problem of the upper limit of ventilation; in addition, the method requires larger bearings and assembly fittings compared with a sleeve type polishing machine in terms of the polishing machine of the same model, and undoubtedly increases the manufacturing cost of the equipment.
Venturi effect: when gas or liquid flows inside the venturi, at the narrowest point of the duct, the dynamic pressure (head of velocity) reaches a maximum, the static pressure (resting pressure) reaches a minimum, and the velocity of the gas (liquid) rises as the cross-sectional area of the flow decreases. The entire inrush current is subjected to the pipe reduction process at the same time, and the pressure is reduced at the same time. Thereby creating a pressure differential that is used to measure or provide an external suction to the fluid.
In conclusion, how to provide a rice polishing machine which is economical and cheap and can supply enough air quantity to a polishing chamber of the rice polishing machine without increasing energy consumption is a technical problem in the industry of the rice polishing machine.
