Description
Technical field
The utility model relates to a kind of car type furnace, relates in particular to a kind of hermetically-sealed construction of car type furnace.
Background technology
Car type furnace is a kind of of industrial furnace.Before the heating, chassis is feeded outside stove, and heating member is placed on the special-purpose parallels, then by haulage gear chassis is drawn in the stove and is heated, by haulage gear chassis is pulled out the outer discharging of stove again after the heating, the workpiece of heating is hung on the forging equipment afterwards or with crane and process.Between the body of heater that comes and goes mobile chassis both sides and fix certain gap will be arranged, when carrying out heating process, fire door falls the stockhole of sealing chassis turnover, and chassis two side clearances also will seal.In heating process, need the pressure that keeps certain in the trolley of gas-fired furnace, to guarantee that heating process is more abundant, the thermal efficiency is higher, and therefore, the sealing of burner hearth concerns heating quality and fuel consumption, is an important requirement.
Chassis two side clearances that generally use now generally are to seal with sand seal.At the bottom of car type furnace, be designed with sand sealing groove, the sand cutter is inserted in the sand launder, be connected as a single entity by sand sealing groove with body of heater at the bottom of making car type furnace, reach body of heater and outside air and isolate, play sealing function.This structure is using the initial stage sealing effectiveness better, but owing to use for a long time, chassis frequently passes in and out body of heater, it rubs with body of heater behind expanded by heating, sealing sand flow in the sand sealing groove loses, and causes body of heater and chassis to damage, and affects the car type furnace whole service life, the sealing of chassis was lost efficacy, reduce the thermal efficiency and the temperature uniformity of car type furnace; And a lot of spaces are arranged between sand grains and the sand grains, extraneous air can enter body of heater by the space between sand grains, makes heated part generation oxidation and decarbonization and affects product quality.
The utility model content
The utility model proposes a kind of long service life, high, the more even and nonabradable car type furnace hermetically-sealed construction of heating of the thermal efficiency for solving the above problem that exists.
For reaching this purpose, the utility model by the following technical solutions:
A kind of car type furnace comprises body of heater, chassis, chassis sand cutter and sand cutter groove, and described chassis is positioned in the body of heater, and chassis contacts the formation contact-making surface with the two sides of body of heater; Be provided with chassis sand cutter on the described chassis, be provided with sand cutter groove on the described body of heater, described sand cutter and the corresponding setting of sand cutter groove, and jointly realize the sealing of furnace sealing face with contact-making surface, the width of the second end of described contact-making surface is slightly larger than the width of first end.
Further, described first end is that chassis is near the position of body of heater inboard.
Further, described the second end is that chassis is near the position of the door side of body of heater.
Further, described chassis comprises wheel, chassis base plate and chassis vehicle body, and described chassis vehicle body top is provided with the chassis base plate, is used for place work piece; Described chassis body bottom is equipped with wheel, is used for the movement of chassis.
Preferably, the base plate of described chassis is inserted in the body of heater.
Preferably, two groups of wheels before and after described chassis is provided with.
Preferably, described car type furnace shell is welded by steel plate and shaped steel.
The beneficial effects of the utility model are: the contact-making surface of the utility model by chassis and body of heater both sides is set to the inclined-plane with certain taper, and namely chassis is slightly larger than chassis near the width of stove inboard near the width of door side position; In body of heater heating process, since the contact-making surface of body of heater and the fitted seal of sand sealing groove and sand cutter, its good sealing effect; Simultaneously, when coming out of the stove, chassis is from the body of heater first end to the second end motion, reduced chassis because of add thermal expansion and cause and the body of heater contact-making surface between friction, effectively prevent the sand seal structural damage, thereby reach the effect of permanently effective sealing, increase the service life.
Description of drawings
Fig. 1 is a kind of car type furnace schematic diagram of the utility model;
Fig. 2 is a kind of car type furnace top view of the utility model.
Among the figure: 1, body of heater; 2, sealing surface; 3, chassis; 4, the first contact-making surface; 5, contact-making surface; 6, first end; 7, the second end; 31, chassis base plate; 32, chassis vehicle body; 33, wheel.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Car type furnace as shown in Figure 1 and Figure 2, it comprises body of heater 1, chassis 3, chassis sand cutter and sand cutter groove; Described chassis 3 is positioned in the body of heater 1, and chassis 3 contacts formation contact-making surface 5 with the two sides of body of heater 1; Be provided with chassis sand cutter on the described chassis 3, be provided with sand cutter groove on the described body of heater 1, described sand cutter and the corresponding setting of sand cutter groove, and with the common sealings that realize furnace sealing faces 2 of contact-making surface 5.
As shown in Figure 1, chassis 3 comprises wheel 33, chassis base plate 31 and chassis vehicle body 32, and its shell is welded by steel plate and shaped steel; Chassis vehicle body 32 tops are provided with chassis base plate 31, are used for place work piece; Its bottom is equipped with wheel 33, is used for the movement of chassis.Preferably, two groups of wheels 33 before and after described chassis 3 is provided with.
In present embodiment, the base plate 31 of chassis 3 is inserted in the body of heater 1.
Among Fig. 2, the contact-making surface of traditional chassis and body of heater is the first contact-making surface 4, and the two ends width of this first contact-making surface 4 is consistent.Behind chassis and body of heater expanded by heating, chassis come out of the stove will with furnace body inside generation serious friction, damage sealing sand, reduce sealing effectiveness, reduce the service life of car type furnace.
And in the utility model, the first end 6 of described contact-making surface 5 is the position of chassis 3 close body of heater 1 inboards, and the second end 7 is the position of the door side of chassis 3 close bodies of heater 1, and the width of the second end 7 is slightly larger than the width of first end 6.Therefore, in body of heater heating process, because the fitted seal with contact-making surface and sand sealing groove and the sand cutter of certain taper of body of heater, its good sealing effect, and it is nearly 15% to improve the efficiency of heating surface, reduction adds thermal losses nearly 10%; Simultaneously; when coming out of the stove; chassis is from the body of heater first end to the second end motion; the gap of chassis and body of heater is increasing, has avoided chassis and body of heater to cause mutual friction because adding thermal expansion, effectively prevents the sand seal structural damage; protected the integrality of chassis and body of heater; thereby reach the effect of permanently effective sealing, 4 times more than of the body of heater of the nearly traditional contact-making surface that increases the service life, and guaranteed the uniformity that body of heater is heated.
The above is preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
