The fire extinguishing device can effectively eliminate sound and reduce noise as well as guarantee a safe, clean and sanitary production environment; furthermore, quenching oil in the oil bath can be prevented from being sputtered, so that the occurrence rate of fire is reduced; and when fire occurs, the oil bath can be sealed, and fire extinguishing can be performed quickly.
Description
Technical field
The present invention relates to a kind of oil quenching bath of heat treatment, especially a kind of extinguishing device being applied to heat-treatment quenching oil sump.
Background technology
At present, when producing the high-abrasive material such as steel ball, abrasion-proof backing block quenching, need to process material, wherein one is exactly quenching, usual employing be oil quenching, the heat treatment mode of oil quenching refers to and adopts from high temperature austenitic tagma the type of cooling of oil to cool down rapidly to obtain a certain specific cryo tissue steel.The equipment carrying out oil quenching is present glowing furnace and oil sump, namely heats in glowing furnace, then enters oil sump cooling.
Existing oil sump is open, and in the cooling procedure of workpiece, because the temperature of the workpiece after Quench heating is very high, higher than the burning-point of oil, oil sump surface there will be moment nature, when the quenching oil in oil sump splashes, and easy initiation fire.Mode traditional at present adopts fire extinguishing gas cylinder directly to carry out spraying the device carrying out putting out a fire, the weak effect of fire extinguishing from periphery to oil sump, and personnel safety is not high yet.And not closed oil sump, also large at the noise carrying out producing in the process of foundry goods cooling, cause the bad environments of production.
Summary of the invention
In order to overcome the above-mentioned deficiency of prior art, the invention provides a kind of heat-treatment quenching oil sump extinguishing device, this extinguishing device defines enclosing to oil quenching bath, can noise elimination noise reduction and ensure the safe clean hygiene of production environment effectively, more can prevent the quenching oil in oil sump from splashing, reducing the probability of happening of fire, can oil sump be sealed again when there is the condition of a fire, reach the object of fire extinguishing rapidly.
The technical scheme that the present invention solves the employing of its technical problem is: comprise the casing be fixedly connected on oil quenching bath opening, the bottom of casing is provided with a pair dodge gate relative with glowing furnace fire door, a pair dodge gate realizes being elevated by steel wire rope, pulley and the hoist engine that is placed on casing top simultaneously, when quenching, dodge gate is opened, and when fire extinguishing, dodge gate is closed.
A kind of heat-treatment quenching oil sump extinguishing device of the present invention, oil quenching bath opening is fixedly connected with a casing, and a pair dodge gate relative with glowing furnace fire door is provided with in the bottom of casing, a pair dodge gate passes through steel wire rope, pulley realizes being elevated with the hoist engine being placed on casing top simultaneously, when quenching, dodge gate is opened, workpiece in glowing furnace after heating enters in oil quenching bath and cools, due to the existence of peripheral casing, the noise reduction produced in high temperature work-piece cools process can be made, and can prevent the quenching oil in oil sump from splashing, reduce the probability of happening of fire, ensure the safe clean hygiene of production environment, when fire extinguishing, dodge gate is closed, oil quenching bath and oxygen are isolated, thus reach the object of fire extinguishing rapidly.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the structural representation of one embodiment of the invention.
In figure, 1, oil quenching bath, 2, crane, 3, dodge gate, 4, casing, 5, upper jack, 6, hoist engine, 7, carbon dioxide cylinder, 8, oil pump.
Detailed description of the invention
For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to protection scope of the present invention.
Fig. 1 shows the structural representation of the present invention's preferred embodiment, a kind of heat-treatment quenching oil sump extinguishing device in figure, comprise the casing 4 be fixedly connected on oil quenching bath 1 opening, oil quenching bath 1 is usually at the pond body structure (as shown in Figure 1) that below ground is formed, and the concrete structure of casing 4 is not limit, it can be the body structure that one or more superposition is communicated with, a kind of concrete structure of casing 4 has been shown in Fig. 1, be bilevel structure, and upper strata box volume is less than lower layer box body, the bottom of casing 4 is provided with a pair dodge gate 3 relative with glowing furnace fire door, a pair dodge gate 3 passes through steel wire rope, pulley realizes being elevated with the hoist engine 6 being placed on casing 4 top simultaneously, a pair dodge gate 3 is linked together by steel wire rope, then by being jointly connected on hoist engine 6 after some grades of pulleys, hoist engine 6 can make two dodge gates 3 be elevated simultaneously, steel wire rope can be the both sides, top (as shown in Figure 1) being connected to dodge gate 3, it can also be the centre being only connected to dodge gate 3 top, also or other positions (being such as connected to bottom or the sidepiece of dodge gate 3) and quantity arrange, as long as can realize drawing dodge gate 3 comparatively securely to move up and down, when quenching, dodge gate 3 is opened, when fire extinguishing, dodge gate 3 is closed.
The concrete connected mode of dodge gate 3 described in the present embodiment and casing 4 is, dodge gate 3 in both sides and casing 4 grafting, and on top by steel wire rope, pulley and hoist engine about 6 opening and closing being placed on casing 4 top.
The dodge gate 3 that alternatively can realize opening and closing function with casing 4 syndeton is, described dodge gate 3 top and casing 4 hinged, and in bottom by steel wire rope, pulley and hoist engine 6 opening and closing being placed on casing top.
As further improvement of this embodiment scheme be, also comprise the crane 2 of about one turnover oil quenching bath 1, workpiece is placed on crane 2, upper jack 5 oscilaltion of crane 2 by setting firmly above it, the side jack that crane 2 is also arranged by its side rocks, the cylinder body of upper jack 5 and side jack is all fixed on casing 4, and upper jack 5 and side jack are all connected by piston rod and crane 2.The major function of crane 2 is the workpiece after holding heating, and sent into oil quenching bath 1 and lower the temperature, after again it is taken out from oil quenching bath 1, crane 2 realizes lifting by the upper jack 5 being fixed on top, and the side jack that crane 2 side is arranged makes crane 2 create to rock, object accelerates workpiece cooling, increases work efficiency.The jack that can automatically control all preferably selected by upper jack 5 and side jack, such as hydraulic jack or Pneumatic jack.
Further Curve guide impeller on the inwall of described casing 4, is provided with breather line, breather line has gas outlet again, and breather line is communicated with by the carbon dioxide cylinder 7 of transfer pipeline with casing 4 outside.When occurring in oil quenching bath 1 and the condition of a fire occurring, not only can take the measure by casing 4 seal isolation, can also pass into carbon dioxide further, thus complete fire extinguishing more rapidly and efficiently, safety coefficient improves again.
Further improving is arrange an oil-out in the bottom of described oil quenching bath 1, and arrange an oil-in at its top, oil-out and oil-in are by forming closed circuit between connection oil pump 8 and oil quenching bath 1.Closed circuit can make the oil circulation in oil quenching bath 1 flow, and impels the fluid acceleration temperature exchange that there is temperature difference in oil quenching bath 1, thus cools workpiece more fully.
