Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater treatment device with a waste gas collection mechanism. Background Technology

[0002] Organic wastewater is wastewater mainly composed of organic pollutants. Organic wastewater easily causes eutrophication of water quality, which is quite harmful. Existing organic wastewater treatment devices generally only treat the wastewater to solve the problem of eutrophication pollution. However, the organic waste gas generated by the volatilization of volatile organic solvents is not treated at all and is released into the air, which can easily cause air pollution. At the same time, the waste gas generated during the wastewater treatment process carries a certain amount of heat.

[0003] A search revealed a utility model patent with publication number CN217391940U, which discloses an organic wastewater treatment device with a waste gas treatment mechanism. The device includes a hollow treatment chamber containing a wastewater treatment room and a waste gas treatment channel surrounding the exterior of the wastewater treatment room. The top of the wastewater treatment room is flush with the top of the inner cavity of the treatment chamber. Inlet and outlet pipes are connected to opposite side walls of the wastewater treatment room. An induced draft fan is installed on the top of the treatment chamber. This utility model integrates wastewater treatment and waste gas treatment into the same chamber. The waste gas treatment channel surrounds the wastewater treatment room, significantly reducing the equipment's footprint. This allows the waste gas generated during wastewater treatment to be promptly cleaned by the waste gas treatment components within the waste gas treatment channel. Furthermore, the heat carried by the waste gas during the cleaning process heats the exterior wall of the wastewater treatment room, improving the wastewater treatment effect and fully utilizing the heat in the waste gas.

[0004] The aforementioned patent merely integrates wastewater treatment and exhaust gas treatment into the same enclosure, allowing the exhaust gas generated during wastewater treatment to be promptly cleaned by the exhaust gas treatment components within the exhaust gas treatment channel. Furthermore, the heat carried by the exhaust gas during this cleaning process heats the outer wall of the wastewater treatment chamber, improving the wastewater treatment effect. However, this fully utilizes the heat in the exhaust gas. It cannot adequately clean or replace the filter components within the wastewater treatment chamber. Traditional methods for cleaning filter components involve disassembling and replacing the entire filter assembly, increasing costs and requiring compatible cleaning components of the same model, which hinders improvements in the filter components' effectiveness in wastewater treatment.

[0005] Therefore, it is necessary to invent a wastewater treatment device with a waste gas collection mechanism to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a wastewater treatment device with a waste gas collection mechanism. Through the arrangement of a cleaning plate and a lifting rod, the repeated lifting and pressing of the lifting rod drives the cleaning plate to scrape the inner and outer sides of the filter screen and the inner side of the activated carbon fiber plate, effectively cleaning the adhering and accumulated particulate impurities on their surfaces and within the filter holes. This improves the wastewater treatment effect of the filter screen and activated carbon fiber plate while significantly reducing the frequency of cleaning and replacement, thus extending their service life. This addresses the problems of existing technologies that cannot adequately clean or replace the filter components within the wastewater treatment chamber. Furthermore, traditional methods of cleaning filter components involve disassembling and replacing the entire filter assembly, leading to increased costs and requiring compatible cleaning components of the same model, which hinders the improvement of the filter components' wastewater treatment effectiveness.

This improves the wastewater treatment effect of filter screen one and activated carbon fiber plate one, while greatly reducing the number of times filter screen one and activated carbon fiber plate one need to be cleaned and replaced, thus extending the service life of filter screen one and activated carbon fiber plate one.

[0015] 2. The expansion of the tension spring keeps the locking block engaged with the slot for a long time. When the guide block slides along the guide groove to assist the rotating block in stable rotation, the locking block will release from the slot and compress the tension spring. The connecting plate that loses its locking effect can be detached as a whole, along with the filter screen, activated carbon fiber board and positioning slot, for easy replacement later.

[0032] The working principle of this practical application is as follows:

[0033] Wastewater enters the wastewater treatment tank 2 through inlet 18 for treatment. The treatment of organic wastewater is existing technology in this field and will not be described in detail here. After treatment, the wastewater is discharged through outlet 19. The filter screen 4 and activated carbon fiber plate 5 are used to filter and treat debris and impurities in the wastewater. Subsequently, the cleaning plate 6 can be used to clean the surface and pores of the filter screen 4 and activated carbon fiber plate 5 by repeatedly applying force to the lifting rod 7. Alternatively, the rotating block 10 can be manually rotated to release the locking block 14 from the locking slot 1. The snap-fit ​​function of 5 allows for the detachment of the connecting plate 3, filter screen 4, and activated carbon fiber plate 5 for easy replacement. When the exhaust pipe 28 is started, it can draw the waste gas generated in the wastewater treatment tank 2 into the waste gas treatment channel 24. The heat of the waste gas can heat the wastewater treatment tank 2, which can effectively improve the wastewater treatment effect in the wastewater treatment tank 2. The waste gas will be filtered and treated by the filter screen 25 and activated carbon fiber plate 26 in the waste gas treatment channel 24. After treatment, it will be discharged through the exhaust port 23.
