[0050] The usage status of the present invention is: the present invention solves the technical problem by adopting the following technical scheme: an electric flocculation purifier used in the catering industry is directly placed in the operation room or near the operation room of the catering store to purify the swill in the operation room; the electric flocculation purifier looks like a file cabinet, and there are four parts of the device inside the box body 1, which are also four modules, namely the electronic control part 2, the sewage pretreatment part 3, the purification part 4 and the sewage storage part. The sewage is put into the filter 6, and the filter basket in the filter box can filter out the particulate matter in the sewage. The sewage after the coarse residue is filtered enters the sewage pretreatment part 3, and the sewage after passing through the sewage pretreatment part 3 flows into the purification part 4. The impurities generated after purification enter the sewage storage part, and the purified water can be discharged.

[0051] The sewage pretreatment part 3 includes a first pre-purification part 31 and a second pre-purification part 32, which are connected by a guide pipe. A baffle 312 is provided in the first pre-purification part 31, and there is a gap between the top of the baffle 312 and the top of the first pre-purification part 31. The sewage enters the first pre-purification part 31 after being filtered for coarse residue through the filter 6. The baffle 312 can separate the first pre-purification part 31. The sewage is further purified by precipitating impurities in the first pre-purification part 31 and close to the water inlet. The sewage after the impurities are precipitated flows into the other side of the baffle 312 of the first pre-purification part 31 through the gap at the top of the baffle 312, and the water level is sensed by the liquid level sensor and the filtering function is judged to be normal, and then it is sucked into the second pre-purification part 32 through the guide pipe. According to the high water level, water is automatically added and the height difference between the water tank and the purification part 4 is used to control the flow rate of water discharged from the water tank, and the sewage flows into the purification part 4.

[0052] A foam scraping device 41 is provided on the top of the purification part 4, and the foam scraping sewage air washing device is located above the electric flocculation purification cabinet. When the point flocculants generated by the electric flocculation purification cabinet float up and accumulate, the motor starts to drive the connecting belt to move, thereby driving the scraper to start. During the movement of the scraper, the flocculated foam is moved from the rear stage to the front stage of the purification device through the scraper on the conveyor belt to cut the scraping layer and convey it to the water inlet. The water foam is separated on the filter net above the water inlet, and the separated sewage is returned to the water inlet for secondary treatment. After the dry foam is compressed by the fan to break the bubbles, it enters the storage container 51 along the sewage discharge channel. After the dirt adhering to the scraper is washed by the wind, it is guaranteed to be discharged cleanly.

[0053] The electrocoagulation purification cabinet is composed of at least one partition board and electrode plate groups respectively arranged between the partition boards. Sewage flows into the space between the partition boards through the first gap, and after passing through the electrode plate groups, it flows into the next pipeline and continues to be purified by the next group of electrode plate groups. The sewage foam generated by electrocoagulation purification is cleaned and discharged by the foam scraping device 41. The impurities precipitated after flowing through the pipeline fall to the bottom of the electrocoagulation purification cabinet. There are multiple partition boards and multiple electrode plate groups in the electrocoagulation purification cabinet. The electrocoagulation purifier can purify swill in multiple stages according to the pipeline type, and sub-partition boards can be set. By obliquely setting the sub-partition boards, the electrode plate groups can be placed obliquely on the sub-partition boards to facilitate further purification of sewage. The pipeline direction of the pipeline-type electrocoagulation purifier is vertically upward, which is convenient for discharging the electrocoagulation flocs with a specific gravity smaller than that of water generated by the electrode plates, and is discharged through the above-mentioned foam scraping and sewage discharging system.

[0054] The water outlet is arranged on one side of the bottom of the box body 1 and is communicated with the electrocoagulation purification cabinet. The purified sewage can be discharged through the water outlet.

[0055] The dirt storage part 5 is located at the bottom of the electrocoagulation purifier. The stored dirt is the waste after water-foam separation and bubble compression by blowing. Its structure is a drawer with bottom wheels, and the dirt is cleaned regularly.

[0056] The dirt storage part 5 has an opening at the bottom or a side opening of the box body 1. The opening method and direction are not limited as long as it is convenient for pushing and pulling the drawer.

[0057] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention.
