Background

Traditional oil storage tank adopts the mode that sets up defeated oil pipe in oil storage tank bottom to carry out oiling and oil discharge, and this has certain drawback to the oil depot that stock solution quality requires highly, the defeated operation of transferring frequently just requires liquid sedimentation operation short.

The floating oil outlet device can effectively avoid the defects, and because impurities such as moisture are deposited under the action of the gravity field, moisture and impurities in the upper-layer fuel oil are always lower than a bottom oil layer, so that the floating oil outlet device is used for extracting the upper-layer oil, and cleaner oil can be discharged, and the service life of downstream purification equipment is prolonged.

The oil outlet end of the floating oil outlet device is connected to an oil outlet short pipe at the bottom of the oil tank, the oil inlet end is suspended below the liquid level through a floating plate and floats up and down along with the lifting of the liquid level, and the floating oil outlet device is usually provided with a support at the bottom of the inner wall of the oil tank so as to support an oil discharge pipe arm. In the folding oil outlet device, the oil outlet arm is longer, and can be contacted with the bottom of the oil storage tank when no floating disc provides buoyancy, so that the oil suction end is damaged, and when the oil in the oil storage tank is completely discharged, the floating disc can be pressed on the oil outlet arm because of no buoyancy support, so that the oil outlet arm bears pressure, and the oil outlet arm is bent and damaged.

To those skilled in the art, the specific meanings of the above terms in the present invention can be understood in light of the present general concepts, in connection with the specific context of the scheme.

Example one

A floating oil discharge type oil storage tank is shown in figures 1-5 and comprises a tank body 1, an oil outlet pipe 2, a folding oil discharge arm 3 and a floater 4.

In this embodiment, the axis of rotation of the first oil discharge pipe 31 with respect to the oil outlet pipe 2 and the axis of rotation of the first oil discharge pipe 31 with respect to the second oil discharge pipe 32 are both horizontal and parallel to each other. For example, the first oil dump line 31, the second oil dump line 32 and the production line 2 are all connected to the swivel joint 34 via a 90 ° elbow 35. By the arrangement, the first oil discharge pipe 31 and the second oil discharge pipe 32 are limited to move in a vertical plane, so that the shape of the tank body 1 which is vertically installed can be better adapted. It is understood that the above-mentioned elbow 35 can be obtained by bending the first oil discharge pipe 31 and the second oil discharge pipe 32, and correspondingly, the oil discharge elbow 33 can also be obtained by bending the second oil discharge pipe 32, that is, the elbow 35 and the oil discharge elbow 33 are integrally formed on the first oil discharge pipe 31 or the second oil discharge pipe 32.

In this embodiment, a connecting plate 36 is fixedly mounted on the oil discharge elbow 33, and the float 4 is connected to the connecting plate 36 through a connecting rod 37, the connecting plate 36 is horizontal when the protection plate 5 is bottomed, and the connecting rod 37 is vertical, so as to maintain the position of the float 4. In addition, the support frame 6 is provided to include a support base 61 and a support rod 62, the top end of the support rod 62 is fixed to the float 4, and the support rod 62 is parallel to the connecting rod 37, and the support base 61 is fixed to the bottom end of the support rod 62 so as to play a role of improving stability by increasing a contact area. It will be understood that the connecting rod 37 is provided at the center of the float 4, and the supporting brackets 6 are arranged in plural and symmetrically on both sides of the connecting rod 37, for example, the supporting brackets 6 are configured in two, one on each side of the connecting rod 37.

When in use, under the buoyancy action of the floater 4, the folding oil unloading arm 3 is in an unfolded state, the oil unloading bent pipe 33 floats and is positioned at a position close to the liquid level of oil, the oil unloading port is not positioned below the liquid level, and at the moment, the oil unloading operation can be carried out through the oil outlet pipe 2; along with the descending of the oil liquid level, the folding oil unloading arm 3 starts to fold, but the oil unloading port of the oil unloading elbow 3 is always positioned below the oil liquid level, so that the normal operation of oil unloading is ensured; after oil has been taken out (or impurity such as oily water has been arranged through blow off pipe 10), float 4 descends and contacts the bottom of the jar body 1 through support frame 6 to obtain supporting, avoid float 4 to unload oil pipe 32 to cause the pressure loss to the second after losing buoyancy, in addition, the existence of protection plate 5 can avoid unloading the bottom that the hydraulic fluid port on the oil return bend 33 directly touched jar body 1, thereby prevent to unload the hydraulic fluid port and appear the damage.
