Embodiment 1

[0032] refer to figure 1 , in the open sewage treatment tank, one end of the sewage treatment tank is provided with a sewage inlet, and the other end is provided with a water outlet; the top of the sewage treatment tank is provided with an oil scraping system, and the oil scraping system is composed of a transmission bracket and a transmission bracket The connected oil scraping combs are connected; the sewage inlet is equipped with a deflector, one end of the deflector is the automatic end, and the other end is connected to one side of the transmission bracket. The setting of the deflector can make it enter the sewage treatment The sewage in the pool is turned from bottom to top, which is conducive to the oil in the sewage being pushed up to the water surface, so that the subsequent degreasing work can be carried out smoothly.

[0033] Preferably, the transmission device includes a transmission roller and a belt matched with the transmission roller, the belt is provided with a...

Embodiment 2

[0035] refer to image 3 and Figure 4 It is a schematic diagram of the specific structure and a schematic diagram of the dispersed structure of the oil scraping device. The oil scraping device described here is connected by an upper elastic extrusion part and a lower comb structure, and a set of springs is arranged below the elastic extrusion part.

[0036] At the same time, there is an oil collecting tank under the oil scraping device. There is an angle of 5 degrees between the fixed bracket and the oil scraping platform, which is conducive to the scraping and falling of grease. One side of the fixed bracket frame is wrapped with an oil-absorbing blanket, and the other side is equipped Oil scraping roller; the comb tooth structure is composed of a comb tooth bar on the bottom plate. hole.

[0037] Further, the oil scraping device and the support frame are rotatably connected, and limit stops are provided on both sides of the bottom plate, and a downward pressure limit bar ...

Embodiment 3

[0040] see figure 1 Among them, an angle of 50 degrees is formed between the fixed bracket and the belt, so that the oil-absorbing felt can be used to absorb oil to the maximum extent, and the oil-absorbing area is expanded at the same time. There are two driving rollers, and the height difference between the two driving rollers is two 1 / 5 of the linear distance between the rollers, the slow lifting here is conducive to the adsorption of grease and the firmness after adsorption.

[0041] Furthermore, a belt bracket is provided between the two driving rollers, and the belt is divided into a first belt working platform and a second belt working platform after being divided by the belt bracket, and the angle between the first belt working platform and the horizontal plane is 3 -10 degrees, the angle between the second belt working platform and the horizontal plane is 40-60 degrees. Setting two different angles here is also to ensure the strength and effect of grease adsorption ...

Abstract

The invention relates to a deoiling and scumming device for a sewage treatment plant. The deoiling and scumming device mainly comprises an open sewage treatment tank and is characterized in that one end of the sewage treatment tank is provided with a sewage inlet while the other end of the sewage treatment tank is provided with a water outlet; an oil scraping system is arranged at the top of the sewage treatment tank and formed by connection of a transmission support and an oil scraping comb connected with the transmission support. The deoiling and scumming device has advantages that a flow guide area can be set according to oil residue quantity, oil absorption felts are arranged in a flow guide area to realize oil isolation, a guide plate is lifted and rotates to a position above an oil residue collection tank along a set time after oil collection is finished, the guide plate is fixedly connected with springs, and an extrusion space is obtained. By the external sleeve type oil scraping comb on the guide plate, oil and scum can be directly filtered into the oil residue collection tank, and accordingly land saving and oil removal are effectively realized. In addition, due to direct transporting, manual salvaging cost is reduced.

Description

technical field [0001] The invention relates to the technical field of oil removal devices, in particular to an oil removal and scum removal device used in sewage treatment plants. Background technique [0002] At present, oil slicks in the steel cutting process, animal and vegetable oils in catering and domestic sewage, and grease scum in petroleum enterprise sewage are all organic pollutants that are difficult to remove and degrade, requiring special hydrolysis acidification tanks, BAF filters, demulsification devices, Large-scale professional equipment such as air flotation pools are used for processing, but each of the above-mentioned facilities covers a large area, high engineering cost, and requires a large amount of labor. If it involves standard upgrading and renovation, the entire treatment system will be required for the renovation process. Long-term outage is quite difficult for the established sewage treatment facilities. At present, there is no land-saving neste...
