Description

Technical Field

[0001] The utility model relates to a lubricating oil tank device used in underground mine production, in particular to a lubricating oil tank device used for underground exploration drilling rigs. Background Art

[0002] In underground mining exploration, fully hydraulic diamond drills are generally used for drilling. During the drilling process, the lubricating oil needs to be intermittently replenished with the help of a lubricating oil tank. Since the lubricating oil used for underground mining exploration drills is usually recycled and not filtered or only simply deposited, the lubricating oil injected into the drill contains a lot of impurities and dirt. Existing lubricating oil tanks generally do not have a flow stabilizing mechanism. Therefore, during the injection of lubricating oil, the oil flow causes the lubricating oil in the tank to be in motion for a long time, which is not conducive to the deposition of impurities and dirt in the oil.

[0003] The Chinese utility model with announcement number CN205824579U discloses a "cone crusher lubricating oil tank", which includes an oil tank body and a flow stabilizer. A plurality of spaced flow stabilizers are arranged in the oil tank body, and the two ends of the flow stabilizer are fixed on the inner wall of the oil tank body. The upper plane and the lower plane of the flow stabilizer are kept at a certain distance from the inner wall of the oil tank body. The lubricating oil containing dust can be kept relatively still in the lubricating oil tank of the crusher, avoiding the problem that the lubricating oil containing dust is constantly stirred by the impact force of the oil supply and return oil in the lubricating oil tank of the crusher and cannot be precipitated, and the lubricating oil contaminated by dust can be effectively precipitated. Since a certain distance is kept between the lower plane of the flow stabilizer and the bottom plate of the oil tank as an oil passage, there is still a problem of too high flow rate of the lubricating oil, and it is difficult to ensure that the lubricating oil remains relatively still in the oil tank, and the flow stabilization effect does not meet the requirements. Utility Model Content

[0004] The problem to be solved by the utility model is to provide a lubricating oil tank device for underground mining exploration drilling rigs, further reducing the oil flow impact during the oil tank filling process, enhancing the deposition effect of impurities and dirt in the lubricating oil, and providing cleaner lubricating oil for the exploration drilling rig.

[0005] A lubricating oil tank device for an underground mining exploration drill comprises a rectangular parallelepiped oil tank body, the oil tank body being surrounded by a top plate, a left side plate, a right side plate, a bottom plate, a rear side plate and a front side plate, two partitions extending forward and backward are fixedly installed in the oil tank body, and the two partitions divide the space in the oil tank body into an oil inlet chamber, a sedimentation chamber and an oil outlet chamber; the upper end of a first partition between the oil inlet chamber and the sedimentation chamber and the upper end of a second partition between the sedimentation chamber and the oil outlet chamber are respectively connected to the top plate There are a first filter screen and a second filter screen; a through hole communicating with the oil inlet chamber is formed on the top plate, and an oil inlet pipe is installed at the through hole; an oil outlet pipe mounting hole communicating with the oil outlet chamber is formed on the right side plate, and an oil outlet pipe is installed at the oil outlet pipe mounting hole; drain holes communicating with the oil inlet chamber, the sedimentation chamber and the oil outlet chamber respectively are formed on the bottom plate, and a first drain plug, a second drain plug and a third drain plug are respectively installed at the drain holes communicating with the oil inlet chamber, the sedimentation chamber and the oil outlet chamber.

[0006] Preferably, a front support plate and a rear support plate are fixedly connected to the lower side of the bottom plate; the upper side of the support plate is tilted upward from left to right to ensure that the bottom plate is tilted upward from left to right.

[0007] Preferably, the oil inlet pipe is threadedly connected to a fuel tank cap; and the fuel tank cap is provided with a vent hole.

[0008] Preferably, the front side plate is provided with an inspection hole communicating with the deposition chamber, and an inspection hole cover is installed at the inspection hole.

[0009] Preferably, a liquid level tube running up and down is installed on the outer side of the right side plate; both ends of the liquid level tube are respectively connected to a liquid level tube elbow communicating with the oil outlet chamber.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] First, using the lubricating oil tank device of the utility model, the lubricating oil is first added to the oil inlet chamber. After the first sedimentation, the lubricating oil in the oil inlet chamber overflows through the first filter screen into the sedimentation chamber. After the second sedimentation, the lubricating oil overflows through the second filter screen into the oil outlet chamber. The impurities and dirt in the lubricating oil are deposited twice and filtered twice, and the cleanliness is greatly improved. On the other hand, since the lubricating oil transitions between adjacent chambers through overflow, the oil flow impact during the oil tank refueling process is further reduced, and the impurities and dirt in the lubricating oil are deposited more fully.

[0012] Second, the utility model has a vent hole on the oil tank cover to ensure that the gas inside the oil tank is discharged smoothly, so as to ensure that the oil inlet pipe can smoothly supply oil. A liquid level tube is provided on the right side plate, through which the amount of oil in the tank can be timely grasped. A drain plug is provided on the bottom plate, which can discharge impurities and dirt inside the tank through the drain hole to ensure the cleanliness of the tank. A support plate with a certain slope is installed under the bottom plate, which can ensure that the bottom plate is in an inclined state, so that the impurities or dirt inside the tank flow to the side where the drain hole is located by gravity, which is convenient for the discharge of impurities and dirt.
