Description

Technical Field

[0001] The utility model relates to a waste oil collection device for a papermaking workshop, in particular to a waste oil collection device used for collecting leaked oil products and oil-gas mixtures in a papermaking workshop. Background Art

[0002] The papermaking machine has unsealed oil contact areas that can cause splashing and leakage of oil and oil-gas mixtures. During the shutdown maintenance and normal operation of the papermaking machine, oil and oil-gas mixtures will continue to leak.

[0003] Papermaking machines are usually placed on the second floor, and some of the leaked oil is condensed by the hot air at the outlet of the second-layer shield and carried to the first floor along the pipeline. The existing method is to build a cofferdam with cement just below the first floor corresponding to the papermaking machine to enclose the leaked oil and oil-gas mixture.

[0004] However, due to its proximity to the ditch, waste oil inevitably mixes with wastewater. In addition, the use of thin oil felt during cleaning produces solid waste that is difficult to separate from the collected oil and oil-gas mixture.

[0005] Therefore, there is still a need to further improve the structure of the existing waste oil collection device. Utility Model Content

[0006] In view of the above problems in the prior art, the purpose of the utility model is to provide a waste oil collection device for a papermaking workshop, which is placed on the first floor corresponding to various leakage locations of the papermaking machines placed on the second floor to collect leaked oil and oil-gas mixture.

[0007] In a first example of the waste oil collection device, the waste oil collection device includes: a side wall; a bottom plate, the bottom plate is sealingly engaged with the side wall at the bottom of the side wall, and the bottom plate and the side wall define a fluid collection space V open upward; a first outlet, the first outlet is arranged on the side wall and adjacent to the bottom plate, and a first valve is arranged at the first outlet, allowing the first outlet to be selectively controlled to be opened and closed; a second outlet, the second outlet is arranged above the first outlet, and a second valve is arranged at the second outlet, allowing the second outlet to be selectively controlled to be opened and closed.

[0008] In a second example of the waste oil collection device, optionally including the first example, the side wall includes a first side wall portion, a second side wall portion opposite to the first side wall portion, a third side wall portion and a fourth side wall portion adjacent to the first side wall portion and the second side wall portion and opposite to each other, wherein the cross-sectional shape of the fluid collection space V on the horizontal plane is a rectangle.

[0009] In a third example of the waste oil collection device, optionally including one or more of the first and second examples, the first side wall portion, the second side wall portion, the third side wall portion, and the fourth side wall portion of the side wall are all inclined and gradually shrink from the top of the side wall to the bottom of the side wall, so that the fluid collection space V is an inverted truncated tetrahedral cone shape.

[0010] In a fourth example of the waste oil collection device, optionally including one or more of the first to third examples, the bottom plate is straight and inclined, and a portion of the bottom plate close to the first outlet is lower than a portion of the bottom plate far from the first outlet.

[0011] In a fifth example of the waste oil collection device, which optionally includes one or more of the first to fourth examples, the first outlet is connected to the ditch through a pipeline, and the second outlet is connected to the oil collection container through a pipeline.

[0012] In a sixth example of the collection device, optionally including one or more of the first to fifth examples, the waste oil collection device further includes a filter screen, which covers the top of the fluid collection space V from above.

[0013] In the seventh example of the waste oil collection device, one or more of the first to sixth examples may be optionally included, and the waste oil collection device further includes: a supporting foot, which is arranged below the bottom plate.

[0014] In an eighth example of the waste oil collection device, optionally including one or more of the first to seventh examples, the support legs have casters and caster locking devices.

[0015] The waste oil collection device of the utility model can collect waste oil and oil-gas mixture during shutdown and normal operation, and the fluid collection space is designed as a waste oil storage tank to prevent waste oil from overflowing.

[0016] The advantage of this device over the cofferdam is that it does not require manual handling and can also reduce the use of thin oil felt rags and other solid waste problems. Regular cleaning is simple and does not generate solid waste. Using a collection device to collect waste oil can also avoid contaminating the ground and reduce the risk of employees slipping when passing by.

[0017] This device can separate waste oil for reuse, and waste oil of poor quality can be avoided from being discharged into the wastewater ditch. This device has the characteristics of environmental protection and safety.

[0018] The entire collection device is designed to be movable. When a large-scale oil leak occurs in the second-layer paper machine equipment at other locations, if the oil leaks to the first layer, the device can be used to collect and move the oil to the location for collection, so as to prevent the leaked oil from flowing into the ditch and the wastewater treatment plant, and to avoid environmental accidents caused by oil leakage. A filter screen is added to the top surface to prevent paper pieces from mixing in and clogging. BRIEF DESCRIPTION OF THE DRAWINGS
