The invention provides a novel sealing device for a heating furnace. The novel sealing device comprises a trolley, rear sealing devices and side sealing devices. Each rear sealing device comprises a first box iron, a first sealing block, a first sealing groove and a first sand tool; the first box iron is arranged, in a C-shaped manner, on the outer side of a face plate of the trolley; the first sealing groove is embedded in the first box iron and is located at the bottom of the first box iron; the first sand tool is fixed on a rear wall; the first sealing block is fixed on the rear wall and the first sand tool; the first sand tool has two bent ends; the bent portion of one end of the first sand tool points to the first sealing groove and is not connected with the first sealing groove. The rear seal of the trolley is double-tool seal, and triple seal is formed for furnace gas, so that the thermal insulation effect is good, energy is saved, the installation is simple, the service life is long and the maintenance is convenient.
Description
Technical field
The present invention relates to mechanical processing industry corollary equipment technical field, be specifically related to the seal arrangement of oven.
Background technique
Industrial furnace is the heat utilizing fuel combustion or electric energy conversion in the industrial production, by the equipment of material or workpiece heat.So, be a very important job to the Seal Design of industrial furnace.The sealing of traditional industrial furnace generally adopts mechanical sealing, such as spring sealed, cylinder-pressing sealing etc., owing to being subject to high-temperature baking, the service life of mechanical sealing is not grown and easily damages, sealing effect is declined, heat in industrial furnace is easy to leak, thus more increases the use of fuel and electric energy, is unfavorable for industrialized production.Time subsequently, the side sealing of oven employs two sand seal as its main sealing means, and have a better effect, but this improves the effect of oven side sealing, do not have overall improvement to the sealing effect of oven, thus the rear sealing of oven also becomes a problem in oven using process.And also two sand seal is not become more meticulous further, thus better heat preservation and energy conservation effects can not be reached.
Therefore, the problems referred to above should be paid attention to and the problem solved in the design and use process of sealing means of oven.
Summary of the invention
For above-mentioned Problems existing, the invention provides oven new type sealing device.
Technical solution of the present invention is: oven new type sealing device, comprise chassis, rear seal arrangement and side-sealing device, described rear seal arrangement comprises the first channel-section steel, first sealing block, first sealing groove and the first sand cutter, described first channel-section steel is that " C " set up of character patt ern is in described chassis panels outside, described first sealing groove is embedded in described first channel-section steel, be positioned at the bottom of described first channel-section steel, described first sand cutter is fixed on rear wall, described first sealing block is fixed on rear wall and described first sand cutter, described first sand cutter is two ends kink shapes, and the bending place of one end of described first sand cutter is pointed to described first sealing groove and is not connected mutually with described first sealing groove,
Described rear seal arrangement has two, in upper and lower laid out in parallel between described chassis and rear wall.
Further improvement of the present invention is: described side-sealing device comprises the second channel-section steel, the second sealing block, the second sealing groove and the second sand cutter, described second channel-section steel is that " C " set up of character patt ern is in described chassis both sides panels outside, described second sealing groove is embedded in described second channel-section steel, be positioned at the bottom of described second channel-section steel, described second sand cutter is fixed on side wall, described second sealing block is fixed on described second sand cutter, described second sand cutter is two ends kink shapes, and the bending part of one end of described second sand cutter inserts in described second sealing groove.
Further improvement of the present invention is: described side-sealing device has two, in being arranged between described chassis and side wall up and down.
Oven new type sealing device of the present invention, adopt the combination of the first channel-section steel, the first sealing block, the first sealing groove and the first sand cutter, chassis is made to enter in body of heater, chassis and rear wall form mazy type double-pole and seal, adopt the combination of the second channel-section steel, the second sealing block, the second sealing groove and the second sand cutter, the two sand seal of mazy type is formed, after chassis enters body of heater to the side sealing of chassis, sand cutter on body of heater side wall inserts in the sealing groove on chassis, thus forms the effect of side sealing.
The invention has the beneficial effects as follows: the rear sealing of oven and side sealing are improved, all adopt labyrinth sealed form, after chassis, sealing adopts double-pole sealing, can form three seals to furnace gas, high insulating effect, energy-conservation and simple, long service life is installed, maintenance is convenient.The two sand seal of plug-in type is adopted to side sealing, there is good using effect.And to the form that rear sealing and side sealing adopt two devices to be arranged above and below, stop on chassis car face with the gas flow under car.The invention enables the rear sealing of chassis and side sealing all to have good heat insulation effect, in the using process of oven, effectively prevent heat in chassis from leaking, thus more decrease the use of fuel and electric energy, meet the requirement of industrialized production.
