Abstract
The utility model relates to a heating furnace, which comprises a furnace body and a furnace door. Vertical sliding grooves are arranged at two sides of the furnace port of the furnace body. A groove inclined inward is respectively arranged on upper and lower parts of the sliding groove. A guide wheel is respectively arranged on and behind both side edges of the furnace door. The distances between upper and lower grooves and upper and lower guide wheels are adoptive, and the internal diameter of the groove is adoptive to the radius of the guide wheel. The heating furnace with the structure can use the component force produced by the inclined groove of the sliding groove, so that the furnace door and the furnace port are closed and kept in the pressure sealing state, thereby sealing the heating furnace.
Description
Technical field
The utility model relates to a kind of heating furnace.
Background technology
The application of heating furnace is very extensive, comprises aging furnace, preheating furnace, boiler, electric furnace, oil oven, steam stove.Being mainly used in spray-painting production line, food production line, oven dry, machine adds, welds, eliminates stress etc.As long as we can say the place of factory heating furnace is just arranged basically, the structure of the fire door of heating furnace mainly contains structures such as door leaf formula, lift, opposite opened, but there is complex structure in these fire doors, sealing is poor, the cost height, deficiencies such as maintenance difficult, Chinese patent specification CN2220593Y discloses a kind of fire door.This fire door cylindrical shell and door closure cooperate section gradient, have characteristics such as good airproof performance, but because the end face of the cooperation of fire door and body of heater is the inclined-plane, increased the volume of fire door and body of heater, structure is also comparatively complicated, the cost height, especially heavier for fire door weight, as to need electrical equipment to promote fire door, more powerful electric block must be set increases lifting force, both increase cost, also increased the space of hold facility.
The utility model content
The purpose of this utility model is: the Compaction of Heating Furnace Door that a kind of simple in structure, easy for operation, good sealing effect is provided.
The purpose of this utility model realizes by implementing following technical proposals:
A kind of heating furnace, comprise body of heater and fire door, it is characterized in that: the fire door both sides of body of heater are provided with vertical chute, the upper and lower of chute is respectively arranged with an intilted groove, the dual-side of fire door respectively is provided with directive wheel up and down, the distance of last low groove and the distance of directive wheel is suitable up and down, the internal diameter size of groove and the radius of directive wheel are suitable.
The gradient α of described groove is the 15-20 degree.
Described door upper part is provided with the electric hoist stove gate device.
Described fire door is provided with suspension ring, is provided with electric block at the body of heater of door upper part.
Described fire door both sides also are provided with directional wheel.
Adopt the Compaction of Heating Furnace Door of above structure, the end face that fire door cooperates with the fire door of body of heater still is the vertical parallel face, but respectively be provided with an inclined groove in the chute top and the bottom of fire door, when fire door in chute to lower slider when the groove, under the gravity effect, the directive wheel of fire door rolls in groove, to the back stop motion of fitting fully of fire door and fire door, utilize the gravity self-locking principle, fire door and stove gate are closed and be the wiper seal state, thereby play sealing effectiveness heating furnace.When needs are opened fire door, fire door upwards to be mentioned, directive wheel skids off from groove, and moves upward along chute and to expose fully up to fire door.When fire door is heavier, can also electric lifting device be set in door upper part, so that carry out the operation of fire door folding, further, be suspension ring to be set at fire door, utilize the electric block that is arranged on door upper part that fire door is lifted by crane.On the fire door side directional wheel is set, can makes fire door in the process of sliding, operate steadily, can in chute, not swing back and forth.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model.
Fig. 2 is that the groove A of fire door one side of Fig. 1 is to schematic diagram.
Fig. 3 is the B portion enlarged drawing of Fig. 2.
Mark among the figure: 1 is body of heater, and 2 is fire door, and 3 is chute, and 4 is inclined groove, and 5 is directive wheel, and 6 is suspension ring, and 7 is electric block, and 8 is directional wheel.
The specific embodiment
Heating furnace as shown in Figure 1, 2, 3 and groove structure thereof, comprise body of heater 1 and fire door 2, the fire door both sides are provided with vertical chute 3, the upper and lower of chute is respectively arranged with an intilted groove 4, gradient α is the 15-20 degree, and the dual-side of fire door respectively is provided with directive wheel 5 up and down, and the fire door both sides also are provided with directional wheel 8, the distance of last low groove and the distance of directive wheel is suitable up and down, the internal diameter size of groove and the radius of directive wheel are suitable.Fire door is provided with suspension ring 6, and the body of heater of door upper part is provided with electric block 7.
Adopt the heating furnace of above structure, when fire door in chute to lower slider when the groove, under the gravity effect, the directive wheel of fire door rolls in groove, to the back stop motion of fitting fully of fire door and fire door, the gravity F that this moment, fire door produced in groove produces F1 and two component of F2 respectively with vertical direction in the horizontal direction, wherein horizontal component F1 and fire door, fire door are vertical, utilize the gravity self-locking principle on inclined-plane, fire door and stove gate are closed and be the wiper seal state, thereby play excellent sealing effect heating furnace.
