Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment agent spreading device. Background Technique

[0002] Sewage treatment is a process of purifying sewage to meet the water quality requirements for discharging into a certain water area or reusing it. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, and catering, and is also increasingly entering the daily lives of ordinary people. In sewage treatment systems using various inorganic coagulants and flocculants such as aluminum salts and iron salts, the sedimentation effect can also be significantly improved.

[0003] Referring to a sewage treatment agent spreading device disclosed in a patent application with a publication number of CN116750851B, when sewage passes through blade one and blade two in this spreading device, when passing through blade two, the sewage drives blade one, blade two, and the shaft body to rotate, thereby realizing the utilization of potential energy. The sliding rod is compressed by the centrifugal force to compress spring two, and the sliding rod moving outward enables the pipe seat to communicate with the rectangular slot hole, facilitating the realization of the sewage treatment agent flowing out along the deep groove for spreading.

[0004] The above-mentioned spreading device can complete the spreading work after recovering the dynamic potential energy of the sewage. However, recovering the dynamic potential energy of the sewage requires providing sewage with a sufficient flow rate to complete the rotation of blade one, and this spreading device relies on the centrifugal force received by the sliding rod to complete the spreading. In this state, blade one needs to provide a certain rotational speed to overcome the pressure exerted by the spring to complete the spreading work, resulting in a large spreading interruption period, unable to quickly start the spreading action, unable to continuously complete the spreading of the sewage treatment agent, and being unfavorable for accurately controlling the dosage of the sewage treatment agent. Content of the Utility Model

A circulating spreading mechanism is installed inside the spreading pipe. The circulating spreading mechanism is composed of a power unit and a spreading unit. The circulating spreading mechanism continuously sends the sewage treatment agent into the spreading pipe to contact with the sewage to complete the spreading action, and a cleaning mechanism is combined and installed on the circulating spreading mechanism. The cleaning mechanism is linked with the circulating spreading mechanism. When the circulating spreading mechanism spreads continuously, the cleaning mechanism is synchronously linked to move to complete the active cleaning work of the circulating spreading mechanism.

A power rod 6 is fixedly installed at the center of the top of the piston head 5. The top of the power rod 6 correspondingly slides through the end cover and the spreading pipe 1, and the power rod 6 correspondingly slides through the top cover. A first inlet pipe 7 is connected and installed at the top of one side of the piston sleeve 4. A first one-way valve for unidirectionally introducing the sewage treatment agent into the piston sleeve 4 is installed at the end of the first inlet pipe 7. A first outlet pipe 8 is connected and installed at the other side of the top of the piston sleeve 4. A second one-way valve for unidirectionally discharging the sewage treatment agent from the piston sleeve 4 is installed at the end of the first outlet pipe 8. A second inlet pipe 9 is connected and installed at the bottom of one side of the piston sleeve 4.

An annular frame 19 is installed concentrically and at intervals outside the annular spray chamber 11. The two synchronous rods 18 correspondingly slide through the top of the spreading pipe 1 and are fixedly connected to the annular frame 19. An annular scraping plate 20 is rotatably installed on the inner wall of the annular frame 19. The annular scraping plate 20 contacts the nozzle 12 to complete scraping and cleaning. An arc-shaped guiding groove 21 is spirally arranged on the inner wall of the spreading pipe 1, and the starting interval range of the arc-shaped guiding groove 21 on the inner wall of the spreading pipe 1 is larger than the starting interval of the up-and-down reciprocating movement of the annular scraping plate 20 to avoid movement interference.

An annular seat is fixedly sleeved on the outer bottom end of the spreading pipe 1, and a plurality of through holes are arranged in a circular array around the annular seat;

[0029] It should be noted that during cleaning: by providing a cleaning mechanism, when the power rod 6 reciprocates up and down, it acts on the two synchronous rods 18 through the pressing plate 17. The annular frame 19 and the annular scraping plate 20 are driven by the two synchronous rods 18 to move up and down synchronously. The annular scraping plate 20 is used to complete the reciprocating scraping and cleaning of the nozzle 12, reducing the subsequent cleaning difficulty. At the same time, when the annular scraping plate 20 moves up and down, under the guidance of the arc-shaped guiding groove 21 and the slider 22, the slider 22 slides under the guidance of the track line of the arc-shaped guiding groove 21, so that the annular scraping plate 20 obtains a rotating effect and can rotate and scrape the nozzle 12, improving the cleaning accuracy of the annular scraping plate 20 for the nozzle 12.

Then, the sewage inlet pipe 13 is connected to the sewage source, and the sewage outlet pipe 14 is connected to the next-stage treatment equipment to ensure the subsequent flow of sewage. By installing a circulating spreading mechanism in the spreading pipe 1, the electric push rod 15 is used to push the piston head 5 to reciprocate up and down. Under the reciprocating action of the piston head 5, the sewage treatment agent is continuously pushed into the annular spray chamber 11 and sprayed out, so that the sewage treatment agent is fully mixed and contacted with the sewage introduced into the spreading pipe 1. Subsequently, the spread sewage is sent out, thus completing the continuous and uninterrupted spreading work of the sewage. At the same time, with the assistance of the cleaning mechanism, the annular scraping plate 20 and the synchronous rod 18 complete linkage, so that the annular scraping plate 20 reciprocates up and down following the power rod 6, thereby completing the scraping and cleaning of the nozzle 12, avoiding the problem that the nozzle 12 is blocked by impurities in the sewage, reducing the subsequent maintenance workload and the maintenance difficulty.
