Description

Technical Field

[0001] This utility model relates to the field of wastewater purification, specifically to an antifoaming spray device. Background Technology

[0002] Wastewater treatment is the process of removing pollutants from urban wastewater, mainly including domestic sewage and some industrial wastewater. It uses physical, chemical, and biological processes to remove pollutants and produce treated wastewater that can be safely released into the environment. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly becoming a part of ordinary people's daily lives. Currently, the use of reverse osmosis membrane technology in wastewater treatment is becoming more and more widespread, mainly because it has a large treatment capacity and produces less high-concentration wastewater. After use, the chemical cleaning of the reverse osmosis membrane is relatively quick and convenient. However, when the cleaning agent is used for aeration and neutralization, it often produces a lot of polluting foam. Because of its light weight, it has strong wind diffusion and can easily pollute nearby water bodies and the environment. Existing devices are not convenient for staff to eliminate the foam inside the wastewater tank in a timely manner.

[0003] In view of this, the inventors of this case conducted in-depth research on the above-mentioned problems, which led to the creation of this case. Utility Model Content

[0024] Reference Figures 1 to 3 :

[0025] A defoaming spray device includes a filter tank 1, a scraping mechanism and a spraying mechanism disposed within the filter tank 1, and a drive mechanism for moving the scraping mechanism and the spraying mechanism within the filter tank 1. Fasteners 11 are respectively engaged on both sides of the filter tank 1. It is worth noting that in this embodiment, the filter tank 1 is open at the top and closed at the bottom.

[0026] The scraping mechanism includes a scraper 21 connected at both ends to fasteners 11 for wiping and cleaning scum from the surface of the filter tank 1, and a filter plate 22 connected to the scraper 21. Specifically, the filter plate 22 includes an L-shaped filter section 221 and a connecting section 222. A plurality of mesh openings are evenly distributed on the filter section 221. Both the filter section 221 and the connecting section 222 are made of high-strength, high-toughness, and corrosion-resistant 304 stainless steel. Specifically, the filter section 221 has a fine mesh with a pore size of 20 meshes and a thickness of 2mm. The filter section 221 is arranged horizontally and above the scraper 21, while the connecting section 222 is arranged vertically. The stainless steel connecting section 222 can be locked to the fasteners 11 with bolts or fixed in other ways to facilitate subsequent replacement, providing both fixation and convenient replacement.

[0027] Furthermore, the scraper 21 includes a first scraper 211 and a second scraper 212. The first scraper 211 is detachably mounted on the fastener 11, and the second scraper 212 is made of high-temperature resistant, wear-resistant, wrinkle-resistant, and highly flexible silicone sheet. The angle between the first scraper 211 and the second scraper 212 is 135-165 degrees. The first scraper 211 is set vertically, and the end of the second scraper 212 that contacts the surface of the liquid in the filter tank 1 is an inclined surface. The silicone second scraper 212 removes impurities that failed to defoam. The first scraper 211 can be locked to the fastener 11 with bolts or fixed in other ways for easy replacement later.

[0028] The spraying mechanism includes a spray pipe 31 connected to two fasteners 11 at both ends, a water inlet pipe 32 mounted on the spray pipe 31, and several nozzles 33 mounted on the spray pipe 31 for spraying and cleaning the foam on the surface of the filter tank 1. The nozzles 33 are arranged at equal intervals along the length of the spray pipe 31. Each nozzle 33 can be controlled by an independent manual valve, which can control the flow rate of the corresponding nozzle 33 as needed, thereby controlling the water pressure of that nozzle 33.

[0029] Furthermore, slide rails 12 are provided on both sides of the filter pool 1 for the fasteners 11 to slide and connect. The two fasteners 11 are movably mounted on the corresponding slide rails 12, so that the fasteners 11, filter plates 22 and scraper plates 21 can be driven by the drive mechanism to move back and forth on the slide rails 12 to clean the surface impurities of the liquid in the filter pool 1.

[0030] Furthermore, the drive mechanism is located on the outside of the filter tank 1. The drive mechanism includes a drive motor 41, a connecting rod 42 connected to the output shaft of the drive motor 41, drive wheels 43 located at both ends of the connecting rod 42, driven wheels 44 located on both sides of the other end of the frame 1, and a transmission belt 45 wound between the drive wheels 43 and the driven wheels 44. Specifically, the drive motor 41 is a bidirectional motor, and the rotation direction of the drive motor 41 can be changed by a switch, thereby controlling the forward and backward movement of the fasteners 11, filter plates 22, and scraper plates 21. The two fasteners 11 are respectively connected to the corresponding transmission belts 45. The drive motor 41 drives the connecting rod 42 and the drive wheels 43 to rotate, thereby driving the transmission belt 45 and the fasteners 11 located on the transmission belt 45 to move. Preferably, the fasteners 11 and the transmission belt 45 are connected by a snap-fit ​​clamp 46, which is fixedly connected to the fasteners 11 by bolts for easy replacement.

[0031] To further reduce the spraying area, air pipes 5 are horizontally installed inside both ends of the filter tank 1, and several air holes are opened on each air pipe 5. The scraping mechanism and the spraying mechanism are located between the two air pipes 5.

[0032] During operation, the bidirectional drive motor 41, connected to an external switch control panel, drives the fastener 11 forward and backward via a selector switch. The filter disc 22 with mesh and the scraper 21 reciprocate on the predetermined slide rail 12, cleaning the undefoamed sludge on the surface of the filter tank 1. Simultaneously, the inlet pipe 32 injects defoaming chemicals into the spray pipe 31 at a certain pressure, and the manual valves of each nozzle 33 are opened. The impact force of the chemicals eliminates the foam on the liquid surface. The flow rate of the nozzle 33 is adjusted according to the amount of foam on the liquid surface corresponding to each nozzle 33, thereby adjusting the water pressure to an appropriate level.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
