Embodiment Construction

[0013] l. Press start key 1, valve f1 opens, valve 2 opens. 2. Tap water enters 1 and 4. When the liquid level of 5 reaches b, valve f1 automatically closes and an alarm informs the operator to add material. When the liquid level of 6 reaches c, valve f2 is automatically closed. 3. Start 2, start 4, add the powder in the bag from the feeding port, due to the vacuum formed by the jet, the powder that floats into the air during the feeding process is drawn into the ejector, mixed with the water in the ejector, and then taken Enter 8. 4. After the feeding is completed, press the start button 2, 3 to start, 3 is a submerged pump with a frequency modulation motor, set the flow rate through the inverter controlled by PLC, and feed to the feeding point or 13, when the liquid level of 5 drops To a, stop at 3, stop feeding to the feeding point, and stop at 2. 5. Valve f4 is closed, valve f3 is opened, water in 8 enters 1, when the liquid level of 6 drops to d, valve f3 is closed, an...

Abstract

The invention relates to a small powder water slurry preparation / feeding apparatus and intelligent control. According to the present invention, lime, active carbon powder and other solid powders with a particle size of more than 200 mesh are added with water, and stirred to prepare a water slurry having a solid content of 5-20%, and the water slurry is conveyed to a wastewater treatment feeding point by using a submerged pump, a hose pump, a separation membrane pump, a rotor pump and the like to treat wastewater so as to achieve the multi-point discharge of the wastewater treatment slurry, the long-distance precise metering transportation and the dust-free powder-to-slurry; and the apparatus has characteristics of high automation degree, precise feeding control, safety, cleanliness and the like.

Description

technical field [0001] The invention relates to a solid slurry preparation / dosing device and an intelligent control method for a small wastewater treatment station. Background technique [0002] Wastewater treatment needs to be prepared and added various solid powder agents, such as activated carbon, lime powder, etc. The powder fineness is greater than 200 mesh, and it is easy to float into the air during the feeding process to form dust pollution, which not only harms various electrical equipment in the wastewater treatment station , It also endangers the health of operating workers. At present, large-scale wastewater treatment stations use large-scale mechanical transmission and bulk powder transport vehicles to feed materials, and add water to prepare slurry in a mixing system equipped with large-scale equipment such as fans and dust removal devices, and use pumps to transport materials to various feeding points to solve this problem. [0003] For the preparation and tr...
