Description

Technical Field

[0001] The invention relates to the technical field of wastewater circulation purification and reuse, and in particular to a wastewater circulation purification and reuse device for a steam boiler. Background Art

[0002] During the use of steam boilers, they need to be supplied with water continuously. The water introduced into the steam boiler carries impurities such as mud and sand. The long-term accumulated mud and wastewater need to be treated regularly. When treating them, they are discharged from the steam boiler. The mud and sand contained in the sediment contain a lot of water, and direct discharge will cause great losses. Therefore, it is necessary to purify it through a wastewater recycling purification and reuse device.

[0003] During use, the existing wastewater recycling purification and reuse device for steam boilers generally removes sediments by natural sedimentation or filter filtration. In order to improve the purification efficiency, filter filtration is adopted. The particle sizes contained in the sediments are different. The more precise the filter, the easier it is to be damaged. Larger particle sediments can easily cause serious damage to this type of filter. At the same time, large particle sediments accumulate on the filter, reducing the utilization rate of the filter, thereby affecting the progress of wastewater recycling purification and reducing the use value of the device.

[0048] Working principle: When in use, when filtering and purifying wastewater, the wastewater is introduced from the top of the purification cylinder 5, and passes through the filter layer 1 301, the filter layer 2 302 and the filter layer 3 303 in turn. The filter holes of the filter layer 1, the filter layer 2 302 and the filter layer 3 303 are gradually reduced from top to bottom, so as to achieve hierarchical filtration of the wastewater. After the wastewater is filtered by the filter layer 1 301, it is introduced into the filter layer 2 302. The electric guide rail 2301 is turned on, and the electric guide rail 2301 drives the long rod 2303 to move, and the scraper 2304 scrapes and separates the static sediment in the wastewater, and the stirring thin rod 2305 and the sediment in the wastewater are stirred.

The separated water enters the bottom of the purification cylinder 5, and the circulation pump 2 is started. The circulation pump 2 re-introduces the purified water into the steam boiler for reuse. After the purification and reuse device has been used for a period of time, the drive motor 4 is started, and the drive motor 4 drives the scraper 14 to rotate. The slag discharge component 19 on the scraper 14 runs accordingly, thereby introducing the precipitated impurities on the filter layer 301 into the slag receiving frame 8. The slag discharge component 19 removes some small particles accumulated on the filter layer 301 during operation. The granular sediment is pushed into the filter layer 2 302 below, and the auxiliary filter component 23 above the filter layer 2 302 starts to work, so as to classify the fallen sediment impurities again. After the classification is completed, the electromagnet 22 is energized, and the electromagnet 22 is adsorbed with the iron block 21. The scraper 2 15 rotates with the rotating shaft 304. The scraper 2 15 pushes the sediment impurities accumulated above the filter layer 2 302 into the slag receiving frame 8. The scraper 3 16 pushes the sediment impurities above the filter layer 303 into the slag receiving frame 8, and the collection of the sediment impurities is quickly completed. After the accumulated sediment is collected, the wastewater is continued to be recycled, purified and reused.
