Problems solved by technology

[0003] At present, the floating sludge and floating objects on the surface of the sewage treatment pool are generally cleared manually. Manual clearing is not only very inconvenient to operate and requires a lot of manpower, but also has low processing and working efficiency, which is not conducive to the sewage treatment. At the same time, it is impossible or difficult to clean up the floating sludge and floating objects in the treatment tanks of different depths, which has high limitations; and the floating sludge and floating objects that are currently picked up may contain relatively large impurities and waste, which cannot be treated Will affect the subsequent work process

Embodiment 1

[0032] Please refer to the attached Figure 2-5 As shown, this embodiment is an easy-to-clean sewage treatment tank scum edge collection device, including a storage box 1, the upper and lower walls of the inner cavity of the storage box 1 are respectively fixed with a first partition 2 and a second partition Plate 3, a crushing assembly 4 is provided between the first partition 2 and the right wall of the storage box 1, a guide plate 5 is provided between the upper end of the second partition 3 and the right wall of the inner cavity of the storage box 1, and the left end of the storage box 1 A cleaning door 6 is hinged, the upper end of the material storage box 1 is connected to the right side with a feed hopper 7, the middle part of the upper end of the material storage box 1 is fixedly connected with a pillar 8, and the upper end of the pillar 8 is fixedly connected with a support cross bar 9, and the lower end of the support cross bar 9 is on the right side A vertical plate...

Embodiment 2

[0043] Please refer to the attached figure 1 As shown, on the basis of Embodiment 1, two first hydraulic cylinders 18 are provided on the top of the inner chamber of the material storage box 1, and the telescopic end of the first hydraulic cylinder 18 is provided with a pressure plate 19, and the right end of the second partition 3 is provided with a second The hydraulic cylinder 20 and the telescopic end of the second hydraulic cylinder 20 move through the second partition plate 3 and are fixedly connected with a second push plate 21 , and a plurality of crushing teeth 22 are fixedly connected with the left end of the second push plate 21 and the lower end of the pressure plate 19 .

[0044] Start the first hydraulic cylinder 18 to drive the pressure plate 19 down to squeeze the floating mud and floating objects in the vertical direction, which can reduce its volume, not only reduce the occupied space, but also facilitate subsequent processing, and then pass the second hydraul...

Embodiment 3

[0046] Please refer to the attached figure 1 As shown, on the basis of Embodiment 1, a filter plate 23 is provided between the second partition 3 and the left wall of the inner cavity of the material storage box 1 , and a drain pipe 24 is communicated with the lower wall of the material storage box 1 .

[0047] The floating mud and floating matter will fall on the filter plate 23 for storage, and the residual sewage and waste liquid in the floating mud and floating matter will fall through the filtering plate 23, and then be discharged through the liquid discharge pipe 24, realizing the cleaning of the floating mud and floating matter. The solid-liquid separation of objects is beneficial to the subsequent treatment of floating sludge and floating objects.

Abstract

The invention relates to an easy-to-clean floating sludge collecting device for a sewage treatment tank. The easy-to-clean floating sludge collecting device comprises a storage box, wherein a crushing assembly is arranged between a first partition plate and the right wall of the storage box, a moving assembly is arranged between a vertical plate and a supporting column, a lifting assembly is arranged at the lower end of a connecting plate, and a collecting frame is connected to the lower end of the lifting assembly. The collecting frame is driven by the moving assembly to move rightwards to the designated collecting distance, the floating sludge collecting distance can be adjusted according to the actual situation, the collecting frame is driven by the lifting assembly to descend to a certain distance in a pond, the descending height of the collecting frame can be adjusted according to treatment ponds with different depths, manual cleaning and fishing are not needed, and the collecting efficiency is improved. Floating sludge and floaters are crushed into small-particle waste through the crushing assembly, follow-up treatment is facilitated, a pressing plate can vertically extrude the floating sludge and the floaters, follow-up treatment is facilitated while occupied space is reduced, then a second push plate transversely extrudes the floating sludge and the floaters, the size is further reduced, the floating sludge and the floaters can be pushed out through the second push plate, and time and labor are saved.

Description

technical field [0001] The invention relates to the technical field of auxiliary equipment for sewage treatment, in particular to an edge-collecting device for floating sludge in a sewage treatment tank that is easy to clean. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. The current sewage treatment plants generally use sewage treatment tanks to treat sewage. In the process of sewage treatment, there are often floating sludge and floating objects on the surface of sewage treatment tanks, which will have a certain impact on the subsequent treatment of sewage. It needs to be cleaned up s...
