Description

Technical Field

[0001] The utility model belongs to the technical field of underground chambers, and in particular relates to a stepped temporary oil storage chamber with an independent air return duct. Background Art

[0002] A large mine in western my country has difficulty in transporting materials due to incomplete system construction. In particular, when transporting fuel, mining trucks cannot reach the site directly and need to be transferred via the middle section road. This is not only laborious and time-consuming, but also the temporary storage of fuel mostly uses existing chambers or connecting roads, which poses certain safety hazards.

[0003] At present, most of the existing temporary storage chambers for oil have the following shortcomings: barreled oil is transported to various middle sections by mining trucks, which require manual loading and unloading, and then transported to various mining work points by flatbed trucks; this method has the disadvantages of high labor intensity and poor working environment. Utility Model Content

[0004] The utility model provides a stepped temporary oil storage chamber with an independent air return duct, aiming to improve the problem of poor storage conditions of the existing temporary oil storage chamber.

[0005] To this end, the utility model adopts the following technical solutions:

[0006] A stepped temporary oil storage chamber with an independent return air duct comprises a ramp, a middle return air duct, a discharge connecting passage and a temporary oil storage chamber, wherein the discharge connecting passage is connected to the temporary oil storage chamber, the head end of the discharge connecting passage is connected to the ramp, and the tail end of the temporary oil storage chamber is connected to the interrupted return air duct; the discharge connecting passage and the temporary oil storage chamber are distributed in a stepped shape, the discharge connecting passage is lower than the temporary oil storage chamber, and the bottom plate of the temporary oil storage chamber forms a temporary oil storage platform; fresh air enters the discharge connecting passage through the ramp, and dirty air flows into the middle return air duct through the temporary oil storage chamber; oil drums are unloaded to the temporary oil storage platform and stored on both sides of the chamber.

[0007] Furthermore, there is a fixed height difference between the bottom plate of the unloading connecting channel and the temporary oil storage platform, which is convenient for manually unloading the oil barrels from the mining truck to the temporary oil storage platform.

[0008] Furthermore, a step is provided between the unloading connecting channel and the temporary oil storage platform.

[0009] Furthermore, the bottom plate of the temporary oil storage chamber is provided with an oil collecting pit to collect spilled oil.

[0010] Furthermore, steel fire doors are provided at both ends of the unloading communication channel and the temporary oil storage chamber.

[0011] The beneficial effects of the utility model are:

[0012] 1. The utility model adopts the mode of combining the unloading connecting channel with the temporary oil storage platform. The unloading connecting channel is connected with the ramp. Fresh air enters the unloading connecting channel through the ramp, and the polluted air flows into the middle return air channel through the unloading platform, thereby forming a through air flow, effectively avoiding the safety hazards caused by poor air flow, and realizing the inherent safety management of the oil chamber with an independent return air channel;

[0013] 2. The utility model leaves a fixed height difference between the unloading liaison road and the temporary oil storage platform. After the mining truck is poured into the unloading liaison road, the bottom of the car body is flush with the temporary oil storage platform, which is convenient for loading and unloading oil barrels, not only saving labor, but also improving the safety of loading and unloading;

[0014] 3. The utility model sets steel fire doors on both sides of the temporary oil storage chamber to prevent the disaster from further expanding in the event of a fire. An oil collection pit is set on the temporary oil storage platform to collect spilled oil, thereby achieving standardized on-site management and further reducing the risk of fire.

[0018] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0019] like Figure 1 and 2 As shown, a stepped temporary oil storage chamber with an independent return air duct includes a discharge liaison channel 3 and a temporary oil storage platform 4. The discharge liaison channel 3 is connected to a ramp 1 and is supported by a double-layer sprayed anchor net. The bottom is poured with concrete with a thickness of 300 mm. A steel fire door 8 is installed at the entrance of the discharge liaison channel 3. The steel fire door serves to prevent the spread and expansion of fire. Fresh air enters the stepped temporary oil storage chamber composed of the discharge liaison channel 3 and the temporary oil storage platform 4 through the ramp 1.

[0020] There is a fixed height difference between the unloading liaison 3 and the temporary oil storage platform 4. On one side of the unloading liaison 3, it is connected to the temporary oil storage platform 4 through a step 5, and the staff can enter the temporary oil storage platform 4 through the step 5. The bottom plate of the temporary oil storage platform 4 is provided with an oil collection pit 6, which can collect spilled oil. The upper part of the oil collection pit 6 is covered with a 4mm thick patterned steel plate. Oil barrels 10 are placed on both sides of the temporary oil storage platform 4. The unloading liaison 3 and the temporary oil storage platform 4 are both supported by double-layer sprayed anchor nets, and the thickness of the support body 7 is 100mm.

[0021] Working principle of this embodiment: After the construction of the main ramp project is completed, the unloading liaison road 3 and the temporary oil storage platform 4 are excavated between the main ramp 1 and the middle return air duct 2. The support method adopts double-layer sprayed anchor net support, and the bottom plate is cast with concrete with a thickness of 300mm. Fresh air enters the unloading liaison road 3 and the temporary oil storage platform 4 through the main ramp 1, and enters the main return air system through the middle air duct 2 after cleaning the chamber. The mining truck 9 enters the unloading liaison road 3 through the ramp, unloads the oil to the temporary oil storage platform 4, and then drives out of the unloading liaison road 3 and returns to the surface through the ramp 1.
