Description

Technical Field

[0001] The utility model relates to the technical field of sewage sludge storage, in particular to a movable oilfield sewage sludge storage device. Background Art

[0002] With the development of the times, people have built more and more oil fields. Oil fields refer to specific areas of crude oil production, and sometimes they are the general term for oil layers accumulated underground in a specific area. During the mining process, oil fields will produce oilfield wastewater and sludge. Oilfield wastewater and sludge contain toxic substances. In order to protect the environment from pollution, it is necessary to strengthen the control of the discharge standards and locations of oilfield wastewater and sludge. Therefore, a movable oilfield wastewater and sludge storage device is needed.

[0003] Most existing oilfield sewage and sludge storage devices use storage tanks to store and transport the sewage and sludge generated in the oilfield together for treatment, and are unable to separate the sewage and sludge. Oilfield sewage and sludge also need to be treated separately after being transported to the treatment site, which causes inconvenience in the treatment of oilfield sewage and sludge. Utility Model Content

[0004] The purpose of the present invention is to provide a movable oilfield sewage sludge storage device to solve the problem that the existing storage tanks proposed in the above background technology cannot separate sewage and sludge, and the oilfield sewage and sludge need to be treated separately after being transported to the treatment site, which causes inconvenience in the treatment of oilfield sewage and sludge. In order to achieve the above purpose, the present invention provides the following technical solutions: A movable oilfield sewage sludge storage device, including a storage frame, a screening assembly is provided inside the storage frame, a discharge assembly is provided inside the storage frame, the screening assembly includes a feed bin, the feed bin is opened inside the storage frame, a separation bin is provided on one side of the feed bin, a water storage bin is provided at the bottom of the separation bin, a first slot is provided inside the feed bin, a primary filter screen is connected to the inside of the first slot, a second slot is provided at the bottom of the separation bin, a secondary filter screen is connected to the inside of the second slot.

[0005] Further preferably, the sub-screening assembly also includes a lifting ring, which is fixedly connected to the top of the primary filter screen, and a pull-out handle is fixedly connected to one side of the secondary filter screen. By installing the sub-screening assembly, the oilfield sewage and sludge mixture can be filtered by the primary filter screen in the first slot to remove large particles after entering the feed bin, and then the mixture enters the separation bin. At this time, due to the action of gravity, the sewage will pass through the secondary filter screen in the second slot into the water storage bin, while the fine sludge will be blocked by the secondary filter screen, thereby separating the oilfield sewage and sludge, and providing convenience for purification treatment after being transported to the treatment site.

[0006] Further preferably, the discharge assembly includes a pushing bin, two of the pushing bins are fixedly connected to one side of the storage frame, a pushing rod is installed on one side of the pushing bin, and the other end of the pushing rod is fixedly connected to a mud pushing plate, and the discharge assembly also includes a closed door, which is movably connected to one side of the storage frame, and a mud guide inclined plate is fixedly connected below the closed door. By installing the discharge assembly, the pushing bin can provide power to the pushing rod, so that after the oilfield sewage and sludge are screened in the storage frame, the pushing rod can push the mud pushing plate to discharge the sludge retained inside, and after opening the closed door, the pushed out sludge will fall from the mud guide inclined plate, thereby improving practicality.

[0007] Further preferably, the top of the storage frame is fixedly connected to a feed pipe, one side of the feed pipe is movably connected to a cover plate, and one side of the storage frame is fixedly connected to a water outlet pipe. By installing the feed pipe, the cover plate can be opened to allow the oilfield sewage and sludge mixture to enter, and then the sewage after screening will enter the water storage tank for storage. When it needs to be discharged, the normally closed water outlet pipe can be opened and connected to the external water pipe, thereby preventing leakage of oilfield sewage and sludge.

[0008] Further preferably, an observation window is provided on the top of the storage frame, a mobile bin is provided on the bottom of the storage frame, and a connecting piece is installed on the front of the storage frame. By installing the observation window, the staff can use the observation window to check the sludge accumulation in the separation bin. The mobile bin facilitates the movement of the entire device and can be connected to the vehicle using the connecting piece, thereby facilitating the transportation of oilfield sewage sludge.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] In the utility model, by installing the screening component, it can be achieved that after the oilfield sewage and sludge mixture enters the feed bin, it will first be filtered by the primary filter in the first slot to remove large particles, and then the mixture enters the separation bin. At this time, due to the effect of gravity, the sewage will pass through the secondary filter in the second slot into the water storage bin, while the fine sludge will be blocked by the secondary filter, thereby separating the oilfield sewage and sludge, and then providing convenience for purification treatment after being transported to the treatment site.

[0011] In the present invention, by installing the discharge assembly, the pushing bin can provide power to the pushing rod, so that after the oilfield sewage and sludge are screened in the storage frame, the pushing rod can push the mud pushing plate to discharge the sludge remaining inside, and after the closed door is opened, the pushed out sludge will fall from the mud guide inclined plate, thereby improving practicality.
