Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment equipment, in particular to an environmentally friendly sludge and garbage cleaning device for sewage treatment. Background Art

[0002] Wastewater treatment and reuse are effective measures for developing and utilizing water resources. Wastewater reuse involves treating municipal and industrial wastewater through biodegradation reactors and other equipment before using it for non-potable purposes such as landscaping, flushing, and replenishing ornamental water bodies. With rapid economic development in recent years and the continuous improvement of people's living standards, the pollution of domestic, industrial, and industrial water has gradually increased with the development of urban construction, making wastewater treatment crucial. During the sewage treatment process, sludge must be separated from the wastewater and purified accordingly. Sludge and other waste also have corresponding treatment methods.

[0003] Chinese invention publication number CN111138001A discloses a sewage treatment equipment with rapid cleaning and continuous filtration. A motor is fixed on one side of the treatment tank.

DETAILED DESCRIPTION

[0026] See also Figures 1 to 7 In an embodiment of the present invention, an environmentally friendly sludge and garbage cleaning device for sewage treatment includes a shell 1, an upper cover 2 is assembled and connected to the upper end of the shell 1, a water inlet 3 is penetrated on the upper cover 2, a water outlet 4 is penetrated at the bottom of the shell 1 and relative to the water inlet 3, a filter plate 5 is fixedly connected to the middle part of the shell 1, a stirring and cleaning mechanism is cooperatively connected to the lower part of the filter plate 5, a pollution guide mechanism is rotatably connected to the upper part of the filter plate 5, and the pollution guide mechanism and the stirring and cleaning mechanism are both transmission-connected to the driving mechanism.

[0027] Furthermore, the filter plate 5 is an arc-shaped filter structure, and the surface of the filter plate 5 is covered with filter cloth. The front and rear sides of the filter plate 5 and the front and rear side walls of the shell 1 are movably opposed to each other, and the two ends of the filter plate 5 are fixedly connected to the two sides of the shell 1. The first sewage pipe 9 is symmetrically penetrated above the end of the filter plate 5 on both sides of the shell 1. The first sewage pipe 9 is provided with a valve. When the sewage passes through the filter plate 5 during treatment, the water passes through the filter plate 5, and the silt impurities are dispersed through the two sides of the filter plate 5 and can be discharged through the first sewage pipe 9.

[0028] In order to ensure the efficiency of cleaning sludge, the stirring and cleaning mechanism includes a first rotating shaft 6 rotatably connected between the front and rear side walls of the shell 1, and a plurality of stirring blades 7 and cleaning blades 8 are fixedly connected to the periphery of the first rotating shaft 6. The stirring blades 7 and the cleaning blades 8 are staggered, and the ends of the stirring blades 7 and the cleaning blades 8 are movably fitted with the lower surface of the filter plate 5. The stirring blades 7 and the cleaning blades 8 are both arc-shaped thin plate structures, and the ends of the cleaning blades 8 are evenly distributed with a plurality of groups of bristles. The first rotating shaft 6 is connected to the driving mechanism in a transmission manner. After the driving mechanism is started, the first rotating shaft 6 can be driven to rotate, thereby stirring the water body through the stirring blades 7 and the cleaning blades 8, and the stirring of the water flow is used to avoid the clogging of the silt on the surface of the filter plate 5 and affecting the passage of the water body. At the same time, the shape of the filter plate 5 can also promote the silt to move to both sides when the water flow impacts, and the cleaning of the cleaning blades 8 can also avoid the adhesion of impurities. These factors combined can better improve the sludge collection efficiency.

[0029] Furthermore, in order to improve the efficiency of clearing blockages, the first rotating shaft 6 includes an outer sleeve 61 and an inner core tube 62 located in the outer sleeve 61, the axes of the outer sleeve 61 and the inner core tube 62 coincide, the stirring blades 7 and the cleaning blades 8 are distributed in a circular array on the periphery of the outer sleeve 61, the end of the outer sleeve 61 is transmission-connected to the driving mechanism, the end of the inner core tube 62 is fixedly connected to the inner wall of the shell 1, the end of the inner core tube 62 is connected to an air pump (not shown in the figure), and a plurality of groups of ventilation holes 63 are provided on the side of the inner core tube 62 facing the filter plate 5, and an air guide groove 71 is provided in the middle of the stirring blade 7, one end of the air guide groove 71 penetrates the end of the stirring blade 7 away from the outer sleeve 61, and the other end of the air guide groove 71 is connected to the inner wall of the outer sleeve 61. In this way, when the drive mechanism drives the outer sleeve 61 to rotate, it can drive the stirring blade 7 and the cleaning blade 8 to rotate synchronously, thereby facilitating the stirring of the water body and also facilitating the cleaning of the sludge block on the filter plate 5. After the air pump is started, air can be inflated into the outer sleeve 61 through the inner core tube 62 and the ventilation holes 63, and the air is discharged through the end of the air guide groove 71. This prevents the adhesion of sludge impurities through the air flow surge, and facilitates the better guidance of sludge to both sides of the filter plate 5. To further prevent the sludge block from clogging, the outer core tube 62 is fixedly provided with a sealing pad 64 on the periphery of the inner core tube 62. The sealing pad 64 slides and fits with the inner wall of the outer sleeve 61. The sealing pad 64 has a notch on the side facing the filter plate 5, and the notch corresponds to the position of the ventilation holes 63. This arrangement can concentrate the airflow on the air guide groove 71 that rotates closer to the filter plate 5, while the air guide groove 71 that rotates away from the filter plate 5 is blocked by the sealing pad 64 and no airflow is discharged, thus not affecting the filtered water body. To prevent sludge and impurities from adhering to and entangled in the filter plate 5, rollers 72 are rotatably connected to the ends of the stirring blades 7. The surfaces of the rollers 72 are radially provided with a plurality of strip-shaped ridges arranged in a circular array. As the stirring blades 7 rotate, the strip-shaped ridges on the rollers 72 scrape the bottom of the filter plate 5, causing it to vibrate. This, combined with the air flow from the air guide grooves 71, effectively prevents sludge and dirt from adhering to and clogging the filter plate.

[0030] To prevent a large amount of sludge from falling directly onto the filter plate 5 and affecting the anti-clogging process, which may result in the inability to quickly and comprehensively clean the blockage due to excessive sludge, the sewage guide mechanism includes a guide assembly and a cleaning assembly. The guide assembly is rotatably connected to the top of the filter plate 5, and one side of the guide assembly and the cleaning assembly are movably opposed to each other. The cleaning assembly is movably assembled and connected to the inside of the shell 1, and a second sewage pipe 15 is provided through the side wall of the shell 1 above the cleaning assembly. The second sewage pipe 15 is provided with a valve. The sewage can initially filter the sludge through the guide assembly. After passing through the guide assembly, the water continues to pass through the filter plate 5. Such multiple sludge interception treatments can improve the efficiency and effectiveness of sludge treatment, while also minimizing the problem of clogging.

[0031] Furthermore, the guide assembly includes two sets of flush and radially rotatably connected second shafts 10 between the front and rear side walls of the housing 1. The outer periphery of the second shafts 10 is fixedly mounted with a transmission wheel shaft 11. The outer periphery of the transmission wheel shaft 11 is mounted with a filter cloth belt 12. A protective block 13 is fixedly mounted on the side of the housing 1 away from the second sewage pipe 15. The protective block 13 is correspondingly arranged with the set of second shafts 10 away from the second sewage pipe 15, and the protective block 13 is movably engaged with the surface of the filter cloth belt 12. The second shafts 10 are in transmission connection with the drive mechanism. After startup, the second shafts 10 can drive the transmission wheel shaft 11 to rotate, so that the filter cloth belt 12 can guide the retained sludge to the side of the cleaning assembly during rotation, and then be discharged from the second sewage pipe 15 after cleaning. This can maintain the filtration effect. A small amount of sludge that has been missed can also be filtered again by the filter screen 5. Both can reduce the processing burden, facilitate improving processing efficiency, effectively reduce the risk of blockage, and ensure the stability of continuous operation.

[0032] Furthermore, the cleaning assembly includes a cleaning block 14, one end of which is slidably engaged and connected to the inner wall of the shell 1 below the second sewage pipe 15, and the other end of the cleaning block 14 is tilted, and the end extends to the transmission wheel shaft 11 for movably adapting. A limiting blind hole 141 is embedded in the lower end of the cleaning block 14 near the inner wall of the shell 1, and a ferromagnetic gasket 142 is embedded in the top of the limiting blind hole 141. A limiting pin 143 is slidably engaged in the limiting blind hole 141, and the top of the limiting pin 143 and the ferromagnetic gasket 142 are movably adapted and magnetically adsorbed. The lower part of the limiting pin 143 is vertically slidably embedded in the inner wall of the shell 1, and the lower end of the limiting pin 143 and the shell 1 are connected by a spring. The cleaning block 14 is easy to disassemble, so that the limit pin 143 can be pressed into the inner wall of the shell 1 during assembly and removal. When assembling and fixing, the limit blind hole 141 and the limit pin 143 can be aligned. At this time, the stable clamping of the cleaning block 14 can be maintained. At the same time, the movable adaptation of one end of the cleaning block 14 and the transmission wheel shaft 11 can ensure that the silt transported on the surface of the filter cloth belt 12 can be scraped by the cleaning block 14 and conveniently discharged through the second sewage pipe 15. The overall use is flexible and convenient, and the interception is efficient.

[0033] The drive mechanism includes a first transmission belt 16 sleeved and fixed to the outer periphery of the end of the second rotating shaft 10, and a second transmission belt 17 sleeved and fixed to the outer periphery of the ends of a set of second rotating shafts 10 and the first rotating shaft 6. The two sets of second rotating shafts 10 drive the upper surface of the filter cloth belt 12 via a drive shaft 11, gradually approaching the second sewage pipe 15. The first rotating shaft 6 and the motor can be connected for transmission, or the motor can drive the rotation of the set of second rotating shafts 10. Once started, the second rotating shafts 10 and the outer sleeve 61 of the first rotating shaft 6 can be driven synchronously, thereby achieving simultaneous sludge conveying and internal cleaning and anti-clogging, mutually reinforcing and improving treatment efficiency.
