Abstract
The invention discloses a closed drain system of a casting shop. The closed drain system of the casting shop comprises a cooling pool (1) and a drain piping system, overflow drain ports (2) are formed in the cooling pool (1), a mixing pool (3) encircling the cooling pool is arranged outside the cooling pool, and overflow drain pipes (4) are arranged on the wall of the mixing pool and connected with the drain piping system through vertical pipes (5). The closed drain system of the casting shop is concise in configuration, water temperature is convenient to control, and sediments are convenient to clean, and the closed drain system solves the problem that potential safety hazards exist in an existing open well gutter drain system.
Description
Technical field
The present invention relates to a kind of foundry drainage system.
Background technology
Common aluminium ingot is by the aluminum ingot continuous-casting machine Foundry Production.The operation principle of continuous casting machine: metal aluminium liquid is emitted from the holding furnace aluminium flowing-out mouth, ship type chute through chute injected water flat continuous casting machine, inject mold and moulding through distributor again, the aluminium ingot of continuous casting machine upper with mold at first through indirect water-cooling but, then the demoulding is sent into the cooling conveyer direct water-cooling but, the last bailing of finished product aluminium ingot.Therefore, continuous casting machine is the finished product aluminium ingot with the metal aluminium liquid Foundry Production cooling procedure is completed by water cooling entirely.
The cooling water of continuous casting machine is supplied with discharging and is completed by foundry's plumbing circulatory system.At present, foundry's continuous casting machine adopts pipe network water supply system and the open well ditch water discharge system of closed.
The collocation form of open well ditch water discharge system is: a side of the length direction of continuous casting machine cooling bay is provided with a plurality of drain stub, every corresponding open Jing Gou of drain stub, adopt water pipe UNICOM between each well ditch, be connected with the workshop drainage pipeline networks more at last.The flow direction of cooling water is: cooling bay-drain stub-open Jing Gou-drainage pipeline networks.
In the aluminium ingot knockout course, may produce the foreign material such as some aluminium slags and enter cooling water.Along with after cooling water enters open Jing Gou, can be deposited in the bottom of open Jing Gou when foreign material, be convenient to concentrate cleaning to draw out.
In whole cooling procedure, cooling water can raise and the generating portion water vapour by a relatively large margin, and the temperature difference can occur, may be over 45 ℃ by water temperature in the well ditch of casting machine head; May adopt open Jing Gou to be convenient to the water vapour discharging less than 45 ℃ by water temperature in the well ditch of casting machine afterbody, make even water temperature, be no more than 45 ℃ to guarantee the cooling water temperature that enters the with no pressure drainage pipeline networks.
Therefore, adopt open well ditch water discharge namely to be convenient to the foreign material of carrying secretly in the continuous casting machine cooling water are drawn out, also be convenient to vent water vapor and control water temperature.But then, open Jing Gou is arranged on and has potential safety hazard on ground surface: the ship shape chute of holding furnace aluminium flowing-out mouth or casting machine and distributor place aluminium liquid may occur and run and leak, aluminium liquid falls in open well ditch, result causes aluminium liquid to meet the major accident that steeping in water for reconstitution is given birth to blast, causes Casting Equipment to be damaged and operating personnel's injures and deaths.In reality, the major accident that meets and blast due to aluminium liquid and cooling water also appearred in foundry.
Summary of the invention
The technical problem to be solved in the present invention: foundry's drainage system that a kind of structure is succinct with configuration and constructability is installed is provided, to guarantee that in whole foundry, ground is dry, eliminates the existing potential safety hazard of existing open well ditch water discharge system.
Technical solution of the present invention: this sealed water discharge system for casting workshop, comprise cooling bay and sewerage system, the Overflow drainage mouth is arranged on cooling bay, cooling bay be provided with outward with its around mixing pit, the mixing pit pool wall is provided with relief sewer, and relief sewer is connected with sewerage system by VERTICAL TUBE.
The Overflow drainage mouth has 6, and is symmetrical along the length direction of cooling bay.Relief sewer has 3.
VERTICAL TUBE is provided with manual pipe valve.
Sewerage system is embedded in underground, and system comprises minute drainpipe of a main drainpipe and corresponding every casting machine, and drainpipe was provided with 3 VERTICAL TUBE of basseting in every minute
Beneficial effect of the present invention:
According to the present invention program, set up outside former cooling bay with its around mixing pit, can increase cooling water inflow, enlarge the backwater area of dissipation, be no more than 45 ℃ to guarantee the cooling backwater temperature that enters the airtight sewerage pipeline network of foundry.
Cooling water enters mixing pit from the Overflow drainage mouth on cooling bay; mixing pit is by the relief sewer draining; the foreign material such as aluminium slag that so just may enter in cooling water are deposited in bottom cooling pond and mixing pit, are convenient to concentrate cleaning to draw out when continuous casting machine is shut down maintenance.
VERTICAL TUBE is provided with manual pipe valve, is convenient to control draining.
The buried foundry of airtight sewerage pipeline network underground, in whole foundry, ground keeps dry, and runs leakage even if occur aluminium liquid in casting process, and the major accident that aluminium liquid is met the water blast can not occur yet.Solved the problem that there is potential safety hazard in existing open well ditch water discharge system.
Description of drawings:
Fig. 1 is drainage system configuration schematic diagram disclosed by the invention.
The specific embodiment:
The common aluminium ingot sealed water discharge system for casting workshop of embodiments of the invention: 200kt/y.
3 16t/h continuous casting machines are selected in design.On every 16t/h continuous casting machine, dispose 1 cooling pond 1,6 Overflow drainage mouths 2,1 cooling backwater mixing pit 3 and 3 parts such as relief sewer 4.
The pre-buried drainage pipeline networks of foundry consists of: 7,3 minutes drainpipes 6 of 1 main drainpipe, and 3 VERTICAL TUBE 5 of drainpipe 6 reservations in every minute are on the ground, and every VERTICAL TUBE 5 is with 1 manual pipe valve.
Two parts are linked into an integrated entity by manual pipe valve by relief sewer 4 and VERTICAL TUBE 5.
The cooling backwater of 16t/h continuous casting machine cooling bay 1 overflows to cooling backwater mixing pit 3 by 6 Overflow drainage mouths 2, after mixing, cooling backwater enters VERTICAL TUBE 5 by 3 relief sewers 4, enter again pre-buried underground minute drainpipe 6 in foundry, import at last main drainpipe 7.In whole drainage procedure, ground is dry, has solved the problem that there is potential safety hazard in existing open well ditch water discharge system.
