Description

Technical Field

[0001] The utility model relates to the technical field of commercial concrete mixing tanks, and particularly relates to a waste water recovery device for cleaning commercial concrete mixing tanks. Background Technique

[0002] During the transportation process, the mixing drum of the commercial concrete mixing tank always rotates to ensure that the transported concrete does not solidify. After transporting the concrete, the inside of the mixing drum is usually washed with water. If the waste water after cleaning is directly discharged, it will not only cause waste of water resources, but also waste of engineering materials because the waste water contains a certain amount of sand and stones. Generally, the waste water is recycled. After retrieval, the patent with the publication number of CN220899722U discloses an overall recovery complete set of equipment for the cleaning waste water of a mixer truck. It can quickly and fully filter the sewage through a circular filter net and a square filter screen, and can quickly clean the remaining sand and stones, so as to facilitate the use of the next filtration, and can also collect the filtered water conveniently and quickly, better and faster ensuring the recovery and treatment of the cleaning waste water of the mixer truck. However, larger gravel in the sewage is easy to accumulate on the circular filter net, resulting in blockage. Therefore, it is necessary to repeatedly pause the filtration of the sewage, remove the larger gravel and then restart the filtration of the sewage, which is more cumbersome to operate. Therefore, a waste water recovery device for cleaning commercial concrete mixing tanks is designed to facilitate the timely cleaning of gravel, avoid the problem of blockage caused by gravel accumulation, and ensure the continuous progress of waste water recovery.

[0021] Embodiment:

[0022] Please refer to Figures 1-4 , a waste water recovery device for cleaning a commercial concrete mixing tank, including a support frame 1, a filter cartridge 2 is arranged on the support frame 1 and a sand and gravel filtration ring belt surrounding the filter cartridge 2, a slag collection trough 7 with an end extending out of the sand and gravel filtration ring belt is arranged below the sand and gravel filtration ring belt, a driving mechanism for driving the sand and gravel filtration ring belt to rotate is arranged on the support frame 1, a sludge filtration mechanism and a dredging mechanism adapted to the sludge filtration mechanism are arranged at the inner top of the filter cartridge 2, and a clean water recovery mechanism is arranged at the bottom of the sludge filtration mechanism.

[0023] Specifically, the sand and gravel filtration ring belt includes a coarse filter screen trough belt 4, and transmission belts 3 are fixedly installed on both sides of the coarse filter screen trough belt 4. Through the coarse filter screen trough belt 4 and the two transmission belts 3, it is convenient to limit the sand and gravel and prevent it from sliding down the side wall of the coarse filter screen trough belt 4.

[0024] Specifically, the driving mechanism includes four transmission rollers respectively arranged at the four corners outside the filter cartridge 2, the two transmission belts 3 are sleeved on the four transmission rollers, a guide roller 5 for guiding the transmission belt 3 is arranged between the two transmission rollers on the same left and right side, and a conveying motor 6 for driving one of the transmission rollers to rotate is also arranged on the support frame 1. Starting the conveying motor 6 is convenient to drive the two transmission belts 3 to rotate, thereby driving the coarse filter screen trough belt 4 to convey. Through the arrangement of the guide roller 5, acute angles are formed on both the left and right sides of the coarse filter screen trough belt 4, so as to facilitate the sand and gravel to fall.

[0025] Specifically, a water collecting hopper 8 is plugged into the top of the filter cartridge 2. Positioning rods 15 are fixedly installed on both sides of the bottom of the water collecting hopper 8. Positioning blocks 16 that are slidably engaged with the positioning rods 15 are fixedly connected to both sides of the top of the filter cartridge 2. Through the setting of the water collecting hopper 8, it is convenient to increase the area for receiving sewage, so that the sewage can fall into the filter cartridge 2 as much as possible. Through the setting of the positioning rods 15 and the positioning blocks 16, it is convenient to disassemble the water collecting hopper 8, so as to conveniently remove the sludge removed by the dredging mechanism from the sludge filtering mechanism.

[0026] Specifically, the sludge filtering mechanism includes a fine filter plate 9 fixedly installed at the inner top of the filter cartridge 2. The dredging mechanism includes a rotating shaft 11 that is hermetically and rotatably connected to the fine filter plate 9. A dredging scraper 10 located above the fine filter plate 9 is fixedly connected to the rotating shaft 11. A dredging motor 12 for driving the rotating shaft 11 to rotate is fixedly connected to the bottom of the filter cartridge 2. Through the fine filter plate 9, it is convenient to filter the sludge in the sewage. By starting the dredging motor 12, it is convenient to drive the rotating shaft 11 and the dredging scraper 10 to rotate synchronously, and the dredging scraper 10 scrapes off the sludge filtered on the fine filter plate 9.

[0028] During use, pour the sewage onto the gravel filtering belt above the filter cartridge 2. The gravel in the sewage is filtered off by the gravel filtering belt, and the remaining sewage falls into the filter cartridge 2. Further filtration is carried out through the sludge filtering mechanism to filter off the sludge in the sewage. The cleaned clean water can be discharged from the filter cartridge 2 through the clean water recovery mechanism. While pouring the sewage, start the driving mechanism to drive the gravel filtering belt to rotate, convey the filtered gravel, and let it fall into the slag collecting tank 7 below. At the same time, start the dredging mechanism to clean the sludge on the sludge filtering mechanism through the dredging mechanism to ensure the continuous progress of wastewater recovery.
