Abstract

The utility model relates to a steel shell furnace, and belongs to metal melting equipment. The steel shell furnace comprises a furnace body and a cooling system which is connected onto the furnace body, wherein the cooling system comprises a water inlet pipe and a water outlet pipe, and joints are connected onto the water inlet pipe and the water outlet pipe; the joints are rotatably connected with the water inlet pipe and the water outlet pipe in a sealing way, and the rotatable seal connection between the joints as well as the water inlet pipe and the water outlet pipe adopts the following structure that: bushes are welded on the water inlet pipe and the water outlet pipe, and fixing rings are sleeved on the bushes; circular bulges for preventing the fixing rings from falling off are arranged on the outer circumferential walls of the bushes, and one end of each joint is welded with a rotating sleeve; and the rotating sleeve is sleeved outside the bush and is connected with the fixing ring, and a sealing ring is arranged between the rotating sleeve and the bush. Under the condition that the tuning of the furnace body is not impeded, a steel pipe is connected between the cooling system and an external water source.

Description

The box hat stove

Technical field:

The utility model relates to a kind of apparatus for melting metal, specifically is a kind of box hat stove.

Background technology:

The box hat stove is a kind of of medium-frequency induction furnace, and it utilizes electromagnetic induction principle to heat usually and melts the metal derby of putting into its body of heater inner chamber, in the process of heatable metal block; Be installed in cooling system on the body of heater and can be in real time the yoke of pressing close to place, molten bath, body of heater center and furnace bottom assembly etc. be cooled off, be connected with two flexible pipes between cooling system and the external water source usually, one-in-and-one-out; Yet flexible pipe is prone to season cracking in the long-time back of using, as long as flexible pipe one is aging; The direct labor just need change it, goes down for a long time, unavoidably can some trouble; Though can use steel pipe to solve the problem of above-mentioned season cracking; But steel pipe can hinder body of heater upset, causes the molten metal after the fusing in body of heater, to pour out.

The utility model content:

The technical problem that the utility model will solve is, provides a kind of under the situation that does not hinder the body of heater upset, can between cooling system and external water source, be connected the box hat stove of steel pipe.

The technical solution of the utility model is; A kind of box hat stove with following structure is provided: comprise body of heater and be connected the cooling system on the body of heater; Cooling system comprises water inlet pipe and outlet pipe; All be connected with joint on water inlet pipe and the outlet pipe, wherein, joint is connected with the outlet pipe rotatable sealing with water inlet pipe.

The described box hat stove of the utility model; Wherein, joint is connected specifically with the outlet pipe rotatable sealing with water inlet pipe and can adopts following structure: all be welded with a lining on water inlet pipe and the outlet pipe, be with retainer plate on the lining; Be useful on the annular protrusion that stops that retainer plate is deviate from the lining periphery wall; Joint one end is welded with rotary sleeve, and rotary sleeve is enclosed within the lining outside and is connected with retainer plate, is provided with sealing ring between rotary sleeve and the lining.

After adopting above structure, compared with prior art, the utility model box hat stove has the following advantages: can hinder the body of heater upset with prior art being connected steel pipe between cooling system and the external water source; Cause the molten metal after the fusing in body of heater, to pour out difference; Joint in the utility model box hat stove is connected with the outlet pipe rotatable sealing with water inlet pipe, and the joint of this connected mode can remain steel pipe straight down with after steel pipe is connected; Promptly when body of heater overturns; Steel pipe will no longer rotate with body of heater, has so just avoided steel pipe to hinder the body of heater upset, therefore; The utility model box hat stove is not hindering under the situation of body of heater upset, can between cooling system and external water source, be connected steel pipe.

Description of drawings:

Fig. 1 is the plan structure sketch map of the utility model box hat stove;

Fig. 2 is the broken section structure for amplifying sketch map of the utility model box hat stove center tap when being connected on the water inlet pipe.

The specific embodiment:

Below in conjunction with the accompanying drawing and the specific embodiment the utility model box hat stove is done further explain:

As depicted in figs. 1 and 2, in this specific embodiment, the utility model box hat stove comprises body of heater 1 and is connected the cooling system on the body of heater 1; Cooling system comprises water inlet pipe 5 and outlet pipe 6; All be connected with joint 2 on water inlet pipe 5 and the outlet pipe 6, joint 2 is connected with outlet pipe 6 rotatable sealings with water inlet pipe 5, and this rotatable sealing connects the concrete following structure that adopts: all be welded with a lining 7 on water inlet pipe 5 and the outlet pipe 6; Be with retainer plate 4 on the lining 7; Be useful on the annular protrusion 10 that stops that retainer plate 4 is deviate from lining 7 periphery walls, joint 2 one ends are welded with rotary sleeve 3, and rotary sleeve 3 is enclosed within the lining 7 outside lugs that also pass through and is connected with retainer plate 4 with bolt; Rotary sleeve 3 inner chambers have annular groove 8, are provided with sealing ring 9 in the annular groove 8.

Above-described embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that those of ordinary skills make the technical scheme of the utility model all should fall in the definite protection domain of the utility model claims.
