Abstract
The utility model discloses a device for oil purification in the shield construction, which comprises an oil tank. A bottom part of the oil tank is provided with an oil inlet. The oil inlet is connected with an oil pump through an oil pipe. The oil pump is communicated with an oil return hole on a top part of the oil tank through an oil return pipe. The top part of the oil tank is provided with anoil unloading hole. The oil unloading hole is connected with the oil pipe through an oil unloading pipe. The oil pipe is connected with an oil cleaner. The product adopts a concept of non-stop oil filtering, and carries out bypass cyclic purification on the most key position of the oil tank in a shield machine so as to guarantee oil quality, satisfy the requirement of the shield construction andavoid the shutdown oil filtering. Moreover, the product has the advantages of high filtering precision, no effect on the viscosity of hydraulic oil in the purification process, no effect on the quality of the hydraulic oil, low operation cost, no wearing parts, no need of replacing a filter element, less power consumption and large capacity, and can also work under the condition of accommodating vast impurities so as to be widely applied to the oil purification in the shield construction.
Description
Technical field
The utility model relates to a kind of purification oil product device, is specifically related to be used to purify the oil product device in a kind of shield-tunneling construction.
Background technique
In shield-tunneling construction, shield machine is because its distinctive construction process, motivational drive all is to be undertaken by hydraulic system basically, hydraulic system is equivalent to the heart of shield equipment, be directly connected to normally carrying out of shield-tunneling construction, especially at the tunneling operation environment comparatively under the condition of severe, be in the condition of high temperature for a long time, can produce a large amount of impurity such as copper scale, iron filings and greasy filth in the hydraulic oil, filter core is stopped up in serious meeting, influence the stability of hydraulic system, must change hydraulic oil at set intervals, otherwise hydraulic system is easy to generate fault.
Can hydraulic system stable operation be directly connected to the operating rate that the shield structure is produced, according to past construction experiences, the fault of hydraulic system has considerable part to be because the unholiness of hydraulic oil causes, therefore improve the turbidity test grade of hydraulic oil, be the key that guarantees hydraulic system stable operation, promptly need to change hydraulic oil at set intervals.
In construction in the past, all be regularly to detect the shield machine oil product, after discovery can't be satisfied the shield-tunneling construction requirement, promptly shut down oil strain, or directly change hydraulic oil, it is longer to expend time in, and cost of material is higher simultaneously.
Summary of the invention
In order to overcome the deficiencies in the prior art; the purpose of this utility model provides a kind of stability of guaranteeing the shield machine hydraulic system; significantly reduced the consumption of hydraulic oil and hydraulic system related accessory; reduced equipment downtime; saved the construction period; increase social benefit and economic benefit, guaranteed the purification oil product device of the progress and the safety of engineering.
The technological scheme that its technical problem that solves the utility model adopts is:
Be used to purify the oil product device in a kind of shield-tunneling construction, comprise fuel tank, described fuel tank bottom is provided with oil inlet hole, oil inlet hole is connected with oil pump by oil pipe, oil pump communicates by the spill port of return tube with the fuel tank top, the top of described fuel tank is provided with unloads oilhole, unloads oilhole and is connected with oil pipe by oil discharge pipe, connects oil cleaning device on the described oil pipe;
As improvement of the technical scheme, described oil pipe is provided with oiling valve; Described return tube is provided with scavenger valve; Described oil discharge pipe is provided with oil drain valve;
As further improvement in the technical proposal, described oil pipe is provided with pressure gauge.
The beneficial effects of the utility model are: this product adopts the notion of not shutting down oil strain; fuel tank position at the shield machine most critical; carrying out bypass circuit purifies; guaranteed oil quality; satisfy the shield-tunneling construction needs, avoided the shutdown oil strain, this product is because filler opening is arranged on the fuel tank bottom; return opening helps the circulation of hydraulic oil at the fuel tank top.In addition, do not influence the hydraulic pressure oil viscosity in the filter precision height of this product, the purification process, do not influence the quality of hydraulic oil, and operating cost is low, does not have easily damaged parts, more renew cartridge, power consumption seldom, capacity is big, holds a lot of impurity and also can work, thereby can be widely used in the oil purification in the shield-tunneling construction.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Embodiment
With reference to Fig. 1, be used to purify the oil product device in a kind of shield-tunneling construction, comprise fuel tank 1, described fuel tank 1 bottom is provided with oil inlet hole, oil inlet hole is connected with oil pump 3 by oil pipe 2, and oil pump 7 communicates by the spill port of return tube 4 with fuel tank 1 top, and the top of described fuel tank 1 is provided with unloads oilhole, unload oilhole and be connected with oil pipe 2, connect oil cleaning device 6 on the described oil pipe 2 by oil discharge pipe 5.
The rotating shaft of a double-spraying type is arranged in the oil cleaning device 6 that this product uses, the pressure-driven rotating shaft high speed rotating that utilizes hydraulic oil to produce, its rotating speed can reach more than 6000 rev/mins, and the centrifugal force that is produced is about more than 2000 times of gravity.Mechanical admixture is separated (fluid is different with impurity proportion) from hydraulic oil under powerful centrifugal action, thereby increases substantially the turbidity test of hydraulic oil.
This product also oil pipe 2 is provided with oiling valve 21 and pressure gauge 22, and described return tube 4 is provided with scavenger valve 41, and described oil discharge pipe 5 is provided with oil drain valve 51.During operation, open oiling valve 21 and pressure-relief valve 51, start oil pump 3, confirm oil pump 3 proper functioning, observe pressure gauge 22 readings, confirm that pipeline is unobstructed, then open scavenger valve 41, observe pressure gauge 22 readings, this moment, oil cleaning device 6 began to rotate; After treating oil cleaning device 6 stability of rotation, shut pressure-relief valve 51, observe pressure gauge 22 readings, confirm that oil cleaning device 6 is working properly.Close when purifying the oil product device when needs, open pressure-relief valve 51 earlier, observe pressure gauge 22 readings, treat oil cleaning device 6 stability of rotation after, close oil pump 3, after oil cleaning device 6 stops operating, close oiling valve 21, scavenger valve 41 and pressure-relief valve 51.
The working principle of this product is: by oil pump 3 with hydraulic oil from fuel tank 1 bottom sucking-off, send in the oil cleaning device 6.Oil cleaning device 6 turning barrels high speed rotating under the effect of pressure oil produces powerful centrifugal force oil that proportion is different and impurity and separates, and hydraulic oil flow oil sump tank 1, impurity are stayed on the inwall of turning barrel.
This product adopts the notion of not shutting down oil strain; fuel tank 1 position at the shield machine most critical; carrying out bypass circuit purifies; guaranteed oil quality; satisfy the shield-tunneling construction needs, avoided the shutdown oil strain, this product is because filler opening is arranged on fuel tank 1 bottom; return opening helps the circulation of hydraulic oil at fuel tank 1 top.In addition, do not influence the hydraulic pressure oil viscosity in the filter precision height of this product, the purification process, do not influence the quality of hydraulic oil, and operating cost is low, does not have easily damaged parts, more renew cartridge, power consumption seldom, capacity is big, holds a lot of impurity and also can work, thereby can be widely used in the oil purification in the shield-tunneling construction.
