Abstract
The utility model relates to the field of titanium alloy ingot smelting, and in particular relates to a cooling and energy-saving device for a vacuum self-consuming furnace. The cooling and energy-saving device for the vacuum self-consuming furnace comprises a primary roots pump, a secondary roots pump, slide valve pumps, a diffusion pump and a rotary vane pump, wherein the primary roots pump is connected with a smelting furnace chamber; the secondary roots pump is connected with the primary roots pump; the slide valve pump is connected with the second roots pump; one end of the diffusion pump is connected with the smelting furnace chamber; and the other end is connected with the secondary roots pump and the rotary vane pump. The cooling and energy-saving device has the effects that the rotary vane pump assists the slide valve pumps in maintaining a vacuum state when the diffusion pump is cooled, and the power of the rotary vane pump is much lower than that of the slide valve pumps, so that the electric quantity consumed by the cooling and energy-saving device is greatly saved under the condition of achieving the same cooling effect and the same cooling time.
Description
Technical field
The utility model relates to the titan alloy casting ingot field of smelting, relates in particular to a kind of consumable electrode vacuum furnace cooling and energy conserving device.
Background technique
In the smelting process of titan alloy casting ingot, generally all be to use first the forvacuum of H-8 slide valve pump below 2000Pa, start 600 Roots pumps, after starting the normal operation of 600 Roots pumps, restart 1200 Roots pumps, open 800 diffusion pumps when vacuum is following to 10Pa, this moment, equipment entered normal operation.
Product cools off diffusion pump needs after burning refining, safety to the following guarantee equipment of 60 degree, and employed cooling unit generally all is to utilize slide-valve gear to change the slide valve pump of air aspiration cavity volume in the prior art, continue operation with a H-8 slide valve pump, because H-8 mechanical pump power is 22Kw, generally need cooling could with the temperature cooling of diffusion pump, take very much electricity in three to four hours.
The model utility content
The purpose of this utility model is to provide a kind of consumable electrode vacuum furnace cooling and energy conserving device, and is existing for long cool time to the diffusion pump cooling unit to solve, and needs frequent problem to its maintenance and maintenance.
For addressing the above problem, technical solution adopted in the utility model is:
A kind of consumable electrode vacuum furnace cooling and energy conserving device comprises one-level Roots pump, secondary Roots pump, slide valve pump, diffusion pump and sliding vane rotary pump, and described one-level Roots pump connects smelts furnace chamber, and the secondary Roots pump connects the one-level Roots pump, and slide valve pump connects the secondary Roots pump; Described diffusion pump one end connects smelts furnace chamber, and the other end connects secondary Roots pump and sliding vane rotary pump.
For making the utility model play better technique effect:
Further technological scheme is that above-mentioned one-level Roots pump is 1200 Roots pumps.
Further technological scheme is that above-mentioned secondary Roots pump is 600 Roots pumps.
Further technological scheme is that above-mentioned slide valve pump is the H-8 slide valve pump.
Further technological scheme is that above-mentioned slide valve pump has two or more.
Further technological scheme is that above-mentioned diffusion pump is 800 diffusion pumps.
Above-mentioned 1200,600 and 800 all refer to each pump delivery, are 1200 liters of per minutes such as 1200 Roots pumps.
The beneficial effect that adopts technique scheme to produce is: when diffusion pump is cooled off, utilize sliding vane rotary pump auxiliary pilot valve pump to keep vacuum state, and the power of sliding vane rotary pump is much smaller than slide valve pump, so reaching same cooling effect and in the situation of same cool time, the spent electric weight of the utility model is saved greatly.
