Technical Field

[0001] The utility model relates to the technical field of ditch floating oil treatment, in particular to a ditch floating oil removing device. Background Art

[0002] The existing rainwater ditch of petrochemical plants generally does not have an oil removal device. When it rains, the oil in the plant will be discharged into the rainwater ditch. If it is not discovered and treated in time, it will cause oil pollution to the environment. In order to avoid oil pollution, the existing operation method is to manually carry oil absorption felt to cover the rainwater ditch when it rains to absorb the floating oil on the surface of the ditch. This method has the problems of untimely and incomplete coverage. Utility Model Content

DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings.

[0021] In one embodiment of the utility model, a device for removing floating oil from a ditch includes a floating frame 1 and a fixed frame 2 arranged at the upper edge of the ditch; one end of the floating frame 1 is hinged on the fixed frame 2, and the other end extends into the ditch 8, and relies on buoyancy to form an inclination angle a of 10 to 80° with the water surface of the ditch; an oil-absorbing felt 4 is arranged on the lower surface of the floating frame; the oil felt absorbs oil but not water and has stable chemical properties, so it can be placed in the ditch for a long time, and can absorb the leaked oil in time when oil leakage occurs.

[0022] In one embodiment of the utility model, one end 41 of the oil-absorbing felt extends to the fixing frame and is fixed to the fixing frame 2 by a clip 7, so that the clip 7 fixes the oil-absorbing felt 4; the other end 42 of the oil-absorbing felt extends out of the floating frame 1, so as to more comprehensively absorb the leaked oil.

[0023] In one embodiment of the utility model, the fixed frame 2 includes a pair of support seats 21, a rotating shaft 5 is fixed to one end of the floating frame 1, and a bearing 6 is provided at both ends of the rotating shaft 5, and the bearing 6 is correspondingly arranged on the support seat 21; so that the floating frame 1 can float on the water surface according to the size of the water flow in the ditch.

[0024] In the above embodiment, a panel 22 for cooperating with the clip 7 to clamp the oil-absorbing felt 4 is disposed above the support seat 21 , so as to facilitate the clip 7 to clamp the oil-absorbing felt 41 and fix it on the fixing frame 2 .

[0025] In one embodiment of the present invention, the width d1 of the floating frame is 10-20 mm smaller than the width d2 of the ditch, ensuring that the floating frame will not be stuck by the edge of the ditch after installation and that the floating frame can float freely up and down.

[0026] In one embodiment of the utility model, the width of the oil-absorbing felt 4 is 5-10 mm greater than the width d2 of the water ditch, ensuring that the oil-absorbing felt 4 can still cover the water ditch laterally after being clamped by the clamp.

[0027] In one embodiment of the present invention, the length L of the floating frame is greater than the height h from the hinge center to the bottom of the ditch, ensuring that the floating frame 1 can still contact the water surface when the water flow is extremely small.

[0028] In one embodiment of the present invention, the floating frame 1 is ladder-shaped and is formed by splicing PVC pipes 11 to ensure that the floating frame 1 can float on the water.

[0029] In the above embodiment, a bottom plate 14 is provided on the lower surface of the floating frame 1, and the bottom plate 14 is one of aluminum sheet and plywood; so that the oil-absorbing felt 4 can better fit under the floating frame 1 and the oil-absorbing felt can be better spread out.

[0030] In one embodiment of the utility model, the floating frame 1 is connected horizontally and vertically by a plurality of PVC pipes 11, and adjacent PVC pipes are connected by a tee 12 or a PVC elbow 13 to form a ladder-shaped floating frame. The floating frame is hinged on one end of the fixed frame 2 and is sleeved with a rotating shaft 5, and both ends of the rotating shaft 5 are fixed in the bearing 6; the rotating shaft 5 is sleeved instead of directly fixing the PVC pipe to the bearing 6, which greatly reduces the wear of the PVC pipe when the bearing 6 rotates, thereby increasing the service life of the floating frame.

[0031] In one embodiment of the present invention, the bearing 6 is arranged horizontally to prevent the floating frame from being stuck with the edge of the ditch due to the deflection direction when floating up and down.

[0032] In actual application, the device is arranged in multiple layers on the ditch when it is not raining. The floating frame floats up and down with the size of the water flow. When oil leaks, the oil-absorbing felt arranged under the floating frame contacts the oil layer to absorb the oil. When the oil-absorbing effect of the oil-absorbing felt deteriorates, the clamp is removed and the oil-absorbing felt is replaced to ensure the oil-absorbing efficiency next time.

[0033] The implementation modes of the present invention are provided for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
