Abstract

The utility model discloses a scum collecting device of a sewage sedimentation tank and the sewage tank adopting the device, and aims to solve the problems that in the prior art, the scum collecting efficiency is low, scum is easy to disturb and fine classification is difficult to realize. The device includes the support frame, is equipped with elevation structure on the support frame, and the dross collection structure is connected to elevation structure's loose end. The scum collecting structure comprises a scum collecting hopper, and at least one detachable baffle is arranged at two ends of the scum collecting hopper. The key is that a plurality of slag filtering plates are connected in a sliding manner along the lifting direction at intervals, slag filtering holes are formed in each slag filtering plate, the pore diameters of the slag filtering holes of the adjacent slag filtering plates are unequal, and the pore diameter of the slag filtering plate above is preferably larger than that below. The scum collecting hopper is preferably funnel-shaped and is initially positioned at the bottom of the funnel-shaped sedimentation tank, scum enters the hopper due to gravity, and fine classification of waste residues with different particle sizes is realized through the multistage slag filtering plates. After the collection is full, the collection hopper is lifted through the lifting structure, and the classified scum can be taken out respectively by opening the baffle. The utility model does not need the repeated movement of equipment in water, avoids the disorder of scum, realizes the source refined classification treatment of waste residues, and has simple structure and convenient operation.

Description

Sewage sedimentation tank scum collection device and sewage tank Technical Field The utility model relates to the technical field of environmental protection engineering, in particular to a sewage sedimentation tank scum collecting device and a sewage tank. Background Along with the acceleration of industrial development and urban process, the production of various types of sewage is increasingly increased, and huge pressure is caused to the water environment. The sewage treatment is a key link of environmental protection, wherein the effective collection and treatment of floating solids such as scum, suspended solids and the like generated in the sewage are of great importance. If the scum is not removed in time, the normal operation and the treatment effect of the sewage treatment system can be affected, and secondary pollution to the environment can be caused. At present, various technical schemes have been developed for collecting scum in a sewage treatment tank. For example, chinese patent application discloses a sewage treatment tank scum collecting device, which includes a driving assembly disposed on an upper surface of a sewage tank and a collecting assembly disposed on a bottom surface thereof, wherein the collecting assembly is driven to move in the sewage tank by the driving assembly to collect scum, and a cleaning unit is provided to clean the collecting tank. However, when such devices are collected, the collection components thereof need to move in the water, which may cause scum to be disturbed and spread to affect the collection efficiency, and at the same time, the collection tank may be cleaned in an incomplete manner or inconvenient to operate. Another type of dross removal apparatus, such as the one disclosed in the chinese patent application, employs a rail traversing the upper portion of the sedimentation tank, and a scraper driver moving along the rail drives a scraper to scrape and collect dross on the water surface, and pushes the dross to a dross collection device at one side for collection and discharge. This approach is mainly directed to the scraping of surface scum, where the scum collection device is usually located on one side of the sedimentation basin, by pushing the scum in with a scraper. There are also waste water slag separating devices, which include a treatment cabinet, a filtering assembly, a slag removing assembly and a lifting assembly, as shown in the Chinese patent. The filtering component comprises a filtering plate and a collecting box, and the wastewater is subjected to solid-liquid separation through filtering holes in the filtering plate and the collecting box. The device makes the filter and the collection box vertically move through the lifting component to be provided with scraping brushes to scrape the inner wall of the treatment cabinet. Analysis of the above prior art can find that they solve the problem of scum collection to some extent, but there are some improvements: 1. The collection mode and efficiency are that when some movable collection devices operate in water, scum is easy to disturb, collection efficiency is affected, and sinking or moving is difficult due to scum accumulation. 2. The scum classification treatment is mainly focused on the collection and removal of scum in most prior art, and the collected scum is often mixed treatment, and the function of effectively classifying and finely classifying the scum with different particle sizes or properties in the collection stage is lacked. This requires additional sorting steps to add complexity and cost to the subsequent differential treatment or recycling of the waste. 3. The structure and maintenance of the device are complex, the number of moving parts is large, and the maintenance cost is high or the device is easy to damage in a severe sewage environment. Therefore, the sewage sedimentation tank scum collecting device which is more optimized in structure, can realize efficient and low-disturbance collection and can carry out refined classification treatment on scum in the collecting process is developed, has important significance for improving sewage treatment efficiency and promoting resource recycling, and is a continuous exploration direction for technicians in the field. Disclosure of utility model The utility model aims to overcome the defects in the prior art, provides a scum collecting device of a sewage sedimentation tank and a sewage tank comprising the device, and aims to solve the problems that the scum collecting efficiency is low, the scum is difficult to realize refined classification, the structure is complex and the like in the prior art. The utility model discloses a scum collecting device of a sewage sedimentation tank, which comprises a supporting frame, wherein a lifting structure is arranged on the supporting frame, the movable end of the lifting structure is connected with a scum collecting structure, the scum collecting structure comprises a scum collecting buck
