Timely lubricate the friction surface to ensure the normal operation of the biomass crusher and extend the service life. The lubricating grease used in the biomass crusher should be determined based on the application conditions, temperature and other conditions of the equipment. Generally, calcium-based, calcium-based or Calcium-sodium based lubrication. When adding lubricating grease, the lubricating grease in the roller bearing box accounts for 50-70% of its body size. It needs to be replaced every 3 months. When changing the engine oil, please use clean gasoline or kerosene to clean the rollers The raceway of the bearing. Before the operation of the biomass grinder, the toggle plate and toggle plate contacts must be filled with grease.
Ash removal method of biomass crusher:
1. Gravity dust removal: It can handle coarse particles of about 100 μm, and is used for coarse dust removal and other fine dust pretreatment. The operation mode is to introduce dust-containing gas into a large-space gravity drop pool, reduce the gas pressure, and use gravity to The particles fall and separate from the gas.
2. Centrifugal dust removal: The inertial force caused by the rotational movement of the gas (hundreds to thousands of times greater than the gravity of the particles) is used to make the solid particles fall along the peripheral wall. The equipment used is a dust collector, and the general entrance speed is 10- 20m\/s, the small particle size that can be captured is 5μm or smaller.
3. Inertial dust removal: It is more suitable for the separation of particles and gases around 5 μm. During the directional baffle period, the smoke gas will impact the baffle of the inertial dust removal equipment, and due to the inertial effect, the particles will be captured. In order to avoid collision Due to the scattering effect, high flow rates cannot be applied.
4. Cleaning and dust removal: Make the gas contact the spray water to trap the solid particles in it. The common spray dust removal tower for biomass grinders introduces gas from the bottom, and sprays water into the mist from the top for countercurrent cleaning and removal. Ash.
5. Electrostatic precipitator: The solid particles in the gas are charged and then attracted to oppositely charged electrodes to achieve the purpose of dust removal. The electrostatic precipitator releases tens of thousands of volts of DC voltage between the metal discharge electrodes, causing 2 Gas ionization between electrodes. When negatively ionized gas collides with solid particles, the solid particles are also negatively charged, attracted to the positive electrode, and fall after neutralizing the charge.
Dust will not only appear on the surface of the biomass grinder, but may also enter the interior. Due to work reasons, dust will also be sucked into the interior, so when removing dust, pay attention to keeping it clean.
