Detailed ways

Calcium oxide from raw material bin 1 in batches is measured by electronic weighing scale 2 and then enters crusher 4 for crushing treatment. The calcium oxide is crushed to a size below 5-10mm, and then lifted to belt conveyor 5 by hoist 3, and the belt The conveyor 5 is transported to the corresponding raw material bins 7, 8, and 9 according to the quality of different batches of calcium oxide, and is stored for use. When the downstream needs high-quality raw materials, the electronic weighing scale 6 and the belt conveyor 12 are used to measure and delivery. When the downstream needs ordinary raw materials, turn on the electronic weighing scale 10 and the belt conveyor 12 to measure and transport, or turn on the electronic weighing scale 6 and 11 at the same time, and then measure and transport them to the belt conveyor at the same time according to the test results. 12. When the raw materials of poor quality products are needed in the downstream, the electronic weighing scale 11 and the belt conveyor 12 are turned on for measuring and conveying. After the test results are matched in a certain proportion, they are simultaneously measured and transported to the belt conveyor 12 to complete the transport. the

When there are high-quality (calcium oxide) raw materials, the method of producing high-quality calcium hydroxide fine powder is to first open the PCL automatic control system, adjust the ratio of the raw material flow in the electronic metering scale 6 to the water flow through the water injection valve 34, and then automatically Open, the raw materials measured by the electronic measuring scale 6 are transported to the first-level digestion machine 13 by the belt conveyor 12, and at the same time, the water injection valve 34 is opened to directly inject water into the first-level digestion machine 13 to react with the raw materials, depending on the reaction degree of digestion and aging. The frequency converter is used to adjust the motor speed of the primary, secondary, and tertiary motors to control the reaction time and process. The high-temperature and high-humidity dust generated by the digestion machine is collected by the dust collector 16 and conveyed by the scraper together with the powder digested by the digestion machine. The machine 18 is transported to the cyclone powder separator 19 for powder selection. The qualified powder (fineness is generally greater than 325 mesh or even higher) enters the elevator 27 by the scraper conveyor 26, and is lifted by the elevator 27 to the scraper conveyor. After 30, it directly enters the fine powder finished product warehouse 28 for storage, and finally there is a packing machine 31 to pack and leave the factory. After the powder is selected, the unqualified coarse powder or particles fall into the scraper conveyor 21, and then the hoist 20 is lifted to the secondary digestion storage. Silo 22 performs redigestion and storage. the

When producing ordinary grade calcium hydroxide powder, first turn on the PCL automatic control system, adjust the ratio of the raw material flow in the electronic weighing scale 10 to the water flow through the water injection valve 34, and then open it automatically. The raw materials are transported to the first-level digestion machine 13 by the belt conveyor 12, or the electronic measuring scales 6 and 11 are matched according to the test results and adjusted to the water flow ratio of the water injection valve 34, and then opened automatically. The raw materials measured by the electronic weighing scales 6 and 11 are transported to the first-level digestion machine 13 by the belt conveyor 12, and at the same time, the water injection valve 34 is opened to directly inject water into the first-level digestion machine 13 to react with the raw materials, depending on the reaction degree of digestion and aging There is a frequency converter to adjust the motor speed of the first, second and third stages respectively to control the reaction time and process. The high-temperature and high-humidity dust generated by the digestion machine is collected by the dust collector 16 and the powder digested by the digestion machine is equipped with a scraper. Conveyor 18 transports to Raymond mill 24 for powder selection. At this time, the rollers of Raymond mill 24 are placed in an idle state without extrusion or grinding, and the fineness and whiteness meet the requirements (generally 150 Mesh-300 mesh), after being absorbed by the negative pressure of the dust collector 25, it is directly lifted by the hoist 27 to the scraper conveyor 30, and then enters the ordinary finished product warehouse 29 for storage. The coarse powder outlet is opened at the bottom of the powder mill 24 to discharge (if there is none, a new discharge outlet needs to be opened at the bottom), and the hoist 20 enters the secondary digestion storage bin 22 for further digestion and standby. the

The method of producing calcium hydroxide powder that does not require high quality and poor quality is to first open the PCL automatic control system, adjust the ratio of the raw material flow in the electronic metering scale 11 to the water flow through the water injection valve 34, and then automatically open it. The raw materials measured by the measuring scale 11 are transported to the first-level digestion machine 13 by the belt conveyor 12, and at the same time, the water injection valve 34 is opened to directly inject water into the first-level digestion machine 13 to react with the raw materials. When the requirements are met, the electronic weighing scales 10 and 11 can also be turned on at the same time according to the test results and a certain ratio is adjusted to adjust the water flow ratio with the water injection valve 34. After the ratio is automatically opened, the raw materials measured by the electronic weighing scales 10 and 11 respectively The belt conveyor 12 transports it to the first-level digestion machine 13, and at the same time, the water injection valve 34 is opened to directly inject water into the first-level digestion machine 13 to react with the raw materials. Depending on the reaction degree of digestion and aging, there are frequency converters to adjust the first-level and second-level respectively. The motor speed controls the reaction time and process, because most poor calcium hydroxide powders do not have high requirements on the degree of ripening and digestion time, so the three-stage digestion machine can not participate in the work at this time, and is in a stopped state (favorable reduce power consumption and energy consumption), the powder after primary and secondary digestion will fall directly into the scraper conveyor 18 through the unloading valve 14 at the tail of the secondary digestion machine (if there is no need to open a new discharge port at the bottom), there is The scraper conveyor 18 is directly transported to the Raymond mill 24 for grinding and powder selection. The high-temperature and high-humidity dust generated by the digestion machine is collected by the dust collector 16 and the powder digested by the digester is also sent by the scraper conveyor 18 Transport to the Raymond mill 24 for powder selection. At this time, the rollers of the Raymond mill 24 are placed in the working state, and the incoming materials are squeezed, ground and powder-selected, and stored in the secondary digestion storage bin 22. Coarse powder materials at various stages after long-term digestion are measured by the electronic weighing scale 23 and then evenly transported to the Raymond mill 24 in proportion to be ground and selected, and the fineness meets the requirements (generally 50 mesh-150 mesh) mesh), after being absorbed by the negative pressure of the dust collector 25, the hoist 27 is lifted to the scraper conveyor 30, and enters the poor finished product warehouse 32, and finally the bulk tanker 33 is loaded to leave the factory, and the unqualified coarse powder also enters the second The secondary digestion storage bin is then digested and circulated for standby, and finally until it is all recycled to the poor finished product bin 32. the
