Description

Technical Field

[0001] The utility model belongs to the technical field of oil sludge treatment, and in particular relates to a floating oil removal device for an oil sludge treatment pool. Background Art

[0002] During the development and production of oil and gas fields, a large amount of oily sludge will be generated due to various reasons, such as ground sludge, tank cleaning sludge, scum sludge, three-separator sludge, oil spill sludge caused by production accidents, etc. These oily sludges are directly discharged into the environment without treatment, which will seriously endanger environmental safety and human health. Therefore, it is necessary to use sludge treatment equipment to treat the sludge before discharge. When treating the sludge, the sludge is first pre-treated and separated in the sludge treatment pool.

However, the oil removal component is not easy to scrape off the floating oil on the inner wall of the treatment tank and can only perform one-way oil removal operations, which reduces the efficiency of removing floating oil.

The screw rod and the sliding rod are respectively arranged in the two installation grooves. The motor is fixedly arranged on the outer wall of the processing tank body. The output end of the motor is fixed to the screw rod. Connecting plates are fixedly arranged on both sides of the first oil pushing plate. The screw rod is threadedly connected to a connecting plate, and the sliding rod is slidably matched with a connecting plate.

[0008] Preferably, the two first oil pushing plates are respectively slidably fitted with the inner wall of the treatment tank body.

[0009] Preferably, a through hole for the output shaft of the cylinder to pass through is opened on the side wall of the treatment tank body, and a sealing ring is arranged in the through hole on the side wall of the treatment tank body.

[0010] Preferably, a guide slope is provided at the inner bottom of the collection tank.

[0011] Preferably, a first valve is disposed inside the oil outlet pipe, and a second valve is disposed inside the oil discharge pipe.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The motor drives the screw to rotate, and then drives the two first oil push plates to move toward each other through the connecting plate. The two first oil push plates push the floating oil on the inner liquid surface of the treatment tank to the middle, and then the output shaft of the cylinder drives the second oil push plate to move forward. The second oil push plate gathers the floating oil to one side, and then the floating oil flows out through the oil outlet pipe, which not only facilitates two-way oil removal operations, but also improves the efficiency of removing floating oil.

[0014] 2. By providing an oleophobic layer on the surfaces of the two first oil pushing plates and the second oil pushing plates, the floating oil can be minimized from adhering to the surfaces of the two first oil pushing plates and the second oil pushing plates. BRIEF DESCRIPTION OF THE DRAWINGS
