Description
Technical field
The utility model relates to a kind of Aluminum overhead traveling crane special-purpose air compressor, particularly a kind of air compressor that comprises tracing system.
Background technique
Modern aluminum industry is produced the general cryolite-aluminium oxide molten salt electrolysis that adopts.In this electrolysis method, molten cryolitic is a solvent, and aluminium oxide is as solute, and as anode, aluminium liquid is as negative electrode with carbon body, feed powerful direct current after, under 950 ℃-970 ℃, carry out electrochemical reaction, both electrolysis on the two poles of the earth in electrolytic bath.Chemical reaction mainly carries out through this equation: 2Al
2O
3==4Al+3O
2, anode reaction: 2O
2--4e-=O
2↑; Cathode reaction: Al
3++ 3e-=Al.Anodic product mainly is carbon dioxide and CO gas, wherein contains harmful gas and solid dusts such as a certain amount of hydrogen fluoride.Therefore, electrolytic aluminium factory is distributed in the extremely low positions of crowd density such as Qinghai, Ningxia, Inner Mongol more.And this reaction is generally carried out on overhead traveling crane, and the air compressor that is used on the overhead traveling crane uses under this environment, can have following problem:
The ambient temperature waviness is bigger, and ambient temperature is generally-15 ℃-65 ℃.The Applicable temperature of conventional exhaust end base of oil injection threaded bolt air compressor is not higher than 40 ℃, therefore, generally the ambient temperature upper limit is done the specific aim design; Promptly strengthen the heat exchange area of air compressor chillers; And increased complete machine internal coolant capacity and circulating load, and installed the thermostat valve assembly additional, increased the performance of cooling system in the air compressor; Keeping complete machine when ambient temperature and intake temperature are 65 ℃, the main frame inside temperature can not surpass 120 ℃ and the negative and positive rotor produced damage.And when complete machine moves in lower ambient temperature, also can keep the moisture of air to exceed freezing and freezing mixture is devalued.Yet in Qinghai, northern area such as Ningxia, Inner Mongol; Winter, temperature was extremely low when arriving, and outdoor temperature often can reach-30 ℃ even lower; And the electrolytic aluminium workshop is because can produce harmful gas and solid dust such as hydrogen fluoride; Must keep the well-ventilated, therefore, room temperature also tends to be low to moderate-15 ℃.In this case; Exhaust end base of oil injection threaded bolt air compression chance takes place owing to temperature is crossed the low situation that causes freezing mixture to freeze, in case freezing mixture freezes, then oil circulation stops; Freezing mixture in the pilot line such as loading hydraulic cylinder also freezes, and air compressor can't normally start.
To this situation, the air compressor that has adopts the method for selecting the lower freezing mixture of pour point.But the freezing mixture that pour point is lower can not be suitable for higher temperature again.Because in case the electrolytic bath in electrolytic aluminium workshop is started working; Temperature in the electrolytic aluminium workshop sharply rises; The temperature of coolant temperature in screw host can be enhanced 120 ℃; At this moment, adverse consequencess such as coking, carbon deposit can take place in the freezing mixture that pour point is lower, bring very big influence for the life-span of screw host.
The model utility content
The utility model purpose is to provide a kind of air compressor that comprises tracing system; Existing air compressor adopts the lower freezing mixture of selection pour point in the existing technology to solve; This freezing mixture is when high temperature environment; Adverse consequencess such as coking, carbon deposit can take place, and bring the technical matters of very big influence for the life-span of screw host.
The utility model purpose realizes through following technological scheme:
A kind of air compressor that comprises tracing system; At least comprise deaerator, return filter, air compression machine host, oil strainer, thermostat valve and oil cooler; Said deaerator, said return filter, said air compression machine host, said oil strainer, said thermostat valve and said oil cooler are in turn connected to form first oil circuit; Said deaerator and said thermostat valve are connected to form second oil circuit, and said first oil circuit and said second oil circuit are provided with tracing system.
Further; Also comprise air intake control valve, inverse proportion valve, unloading/loading hand behaviour's valve and atmospheric valve; Said air intake control valve is connected with said air compression machine host; Said air intake control valve, said inverse proportion valve, said unloading/loading hand behaviour valve, said atmospheric valve and said deaerator are in turn connected to form first gas circuit, and said first gas circuit is provided with tracing system.
Further, said tracing system comprises heating tape and heating resistance collar, and said heating tape is arranged on said first oil circuit, said second oil circuit and said first gas circuit, and said heating resistance collar is set on the said deaerator.
Compared with prior art; The tracing system of the utility model can prevent that the freezing mixture of air compressor from freezing; Make air compressor under low temperature environment, not adopt the lower freezing mixture of pour point also can normally start, can avoid selecting the lower freezing mixture of pour point and the problem brought occurs.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing, specify the utility model.
See also Fig. 1; A kind of air compressor that comprises tracing system of the utility model; At least comprise deaerator 5, return filter 6, air compression machine host 1, oil strainer 2, thermostat valve 3 and oil cooler 4; Deaerator 5, return filter 6, air compression machine host 1, oil strainer 2, thermostat valve 3 and oil cooler 4 are in turn connected to form first oil circuit, and deaerator 5 is connected to form second oil circuit with thermostat valve 3, and first oil circuit and second oil circuit are provided with tracing system.
Further; Also comprise air intake control valve 7, inverse proportion valve 8, unloading/loading hand behaviour's valve 9 and atmospheric valve 10; Air intake control valve 7 is connected with air compression machine host 1; Air intake control valve 7, inverse proportion valve 8, unloading/loading hand behaviour valve 9, atmospheric valve 10 and deaerator 5 are in turn connected to form first gas circuit, and first gas circuit is provided with tracing system.
Further, tracing system comprises heating tape and heating resistance collar, and heating tape is wrapped on first oil circuit, second oil circuit and first gas circuit, and heating resistance collar is set on the deaerator.
When air compressor work or ambient temperature were higher, heating tape on first oil circuit, second oil circuit and first gas circuit and the heating resistance collar that is set on the deaerator were in closed condition.When ambient temperature was low, after air compressor quit work, heating tape and heating resistance collar were opened automatically, and kept working state, can guarantee that freezing mixture can not freeze, in case after the normal startup of air compressor, heating tape and heating resistance collar are closed automatically.At this moment, freezing mixture relies on the heat of pressurized air conduction to heat up the air compressor proper functioning rapidly.
The tracing system of the utility model can prevent that the freezing mixture of air compressor from freezing, and makes air compressor under low temperature environment, not adopt the lower freezing mixture of pour point also can normally start, and can avoid selecting the lower freezing mixture of pour point and the problem brought occurs.
More than the disclosed several specific embodiments that are merely the application, but the application is not limited thereto, any those skilled in the art can think variation, all should drop in the application's the protection domain.
