Example one

As shown in fig. 1 to 4, the present invention relates to a hydrogen regulating oil tank for reducing hydrogen gas entering into a vacuum oil tank along with sealing oil, so as to save cost.

As shown in fig. 1, the hydrogen regulating oil tank comprises an oil tank body 1, an oil inlet pipe 2, a hydrogen recovery pipe 3, an oil outlet pipe 4, an oil level switch 5, a switch valve 6 and a filter screen 7; the oil inlet pipe 2 and the hydrogen recovery pipe 3 are both arranged at the upper part of the oil tank body 1, and the switch valves 6 are arranged on the oil inlet pipe 2 and the hydrogen recovery pipe 3; the filter screen 7 is located in the oil tank body 1, just the filter screen 7 separation in go out the oil inlet of oil pipe 4 with advance between oil pipe 2 and the hydrogen recovery pipe 3, be equipped with on going out oil pipe 4 oil level switch 5.

The utility model discloses in, through setting up the separation of filter screen 7 in go out oil pipe 4 the oil inlet with advance oil pipe 2 with between the hydrogen recovery pipe 3, and then advance oil pipe 2 and pour into the sealing oil and advance when in the oil tank body 1, the sealing oil process filter screen 7 to partial hydrogen bubble in the sealing oil is by filter screen 7 blocks, makes partial hydrogen bubble can not get into to going out oil pipe 4 along with sealing oil in, leads to the hydrogen loss.

In this embodiment, the oil level switch 5 is a float valve so that when the sealing oil reaches a set water level, the float valve opens the oil outlet pipe 4 to allow the sealing oil to enter the oil outlet pipe 4.

The filter screen 7 is in a flat plate shape, four sides of the filter screen 7 are correspondingly fixed on the inner side walls of four sides of the oil tank body 1, and the oil inlet of the oil outlet pipe 4 is positioned below the filter screen 7; through setting up flat filter screen 7 to separate and locate advance oil pipe 2 with go out between the oil pipe 4, guarantee advance the sealed oil that oil pipe 2 was irritated and pass through filter screen 7 before getting into out oil pipe 4 and filter, make partial hydrogen bubble can be kept off by filter screen 7 to float out sealed oil and carry out the recovery of hydrogen through hydrogen recovery pipe 3 after 1 upper portion of oil tank body, avoided the waste of hydrogen, saved the cost of preparation hydrogen.

In this embodiment, the filter 7 is horizontally disposed in the oil tank body 1 and located in the lower region of the oil tank body 1 to block hydrogen bubbles in the sealing oil and recycle hydrogen.

As shown in fig. 2, in other embodiments, the filter screen 7 is obliquely arranged in the fuel tank body 1, so that hydrogen bubbles blocked on the filter screen 7 have a tendency to rise upwards, and the loss of hydrogen can be reduced more; simultaneously, filter screen 7 slope sets up and can increase filter screen 7's area to block more hydrogen bubbles, improve the efficiency of hydrogen recovery, and reduce the influence to the sealing oil velocity of flow.

Preferably, the upper part of the filter screen 7 is provided with a plurality of air guide rods 8 with smooth surfaces, and the air guide rods 8 are arranged along the inclined direction of the filter screen 7, so that hydrogen bubbles blocked on the filter screen 7 easily rise along the air guide rods 8, thereby facilitating the recovery of hydrogen.

Further, air guide rod 8's cross section is semicircular, air guide rod 8's plane is fixed in filter screen 7 upper portion, and then block hydrogen bubble on filter screen 7 upper portion can move to along air guide rod 8's arc surface top to make and fuse at the arc surface top at a plurality of hydrogen bubbles, increase hydrogen bubble's volume is followed sooner air guide rod 8 rises to 1 upper portion of oil tank body, perhaps directly breaks away from again air guide rod 8 rises to 1 upper portion of oil tank body is favorable to improving the efficiency that hydrogen was retrieved.

In this embodiment, filter 7 is metal filter 7, and then guarantees the firmness of filter 7 structure is in order to guarantee filter 7 can block hydrogen bubble smoothly, guarantees the normal recovery of hydrogen.

In other embodiments, the screen 7 may also be a screen 7 made of a composite material, to be specifically selected according to the needs.

Example two

The difference between the second embodiment and the first embodiment is the structure of the filter screen 7.

As shown in fig. 3, the filter screen 7 is an inverted cylinder, and the filter screen 7 covers the oil inlet area of the oil outlet pipe 4, so that the size of the filter screen 7 is reduced on the premise of blocking hydrogen bubbles from entering the oil outlet pipe 4, thereby saving cost.

EXAMPLE III

The difference between the third embodiment and the first embodiment is the structure of the filter screen 7.

As shown in fig. 4, the filter screen 7 is horizontally arranged in the oil tank body 1, the filter screen 7 is wavy, and the oil inlet of the oil outlet pipe 4 is located below the filter screen 7; on the first hand, the hydrogen bubbles blocked by the upper part of the filter screen 7 can rise along the gradient of the filter screen 7, and can be fused with other hydrogen bubbles at the top of the wavy filter screen 7 to form hydrogen bubbles with larger volume, and the hydrogen bubbles can quickly rise to the upper part of the oil tank body 1, so that the hydrogen recovery efficiency can be accelerated; in the second aspect, the filter screen 7 is wavy, which is beneficial to increase the area of the filter screen 7 so as to block more hydrogen bubbles and improve the hydrogen recovery efficiency.

To sum up, for prior art, the utility model discloses a in the case of transferring hydrogen, will filter screen 7 set up in the oil tank body 1 to play the effect of retrieving hydrogen, and then avoid setting up special hydrogen eduction gear again in the case outside of transferring hydrogen and collect hydrogen, lead to occuping too many spaces and increase equipment cost.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
