Abstract
The utility model discloses a furnace door structure for a tunnel furnace, which comprises a furnace door and a furnace door lifting mechanism, wherein both sides of the furnace door are provided with a support; the upper end of the support is connected with a cross beam; the cross beam is provided with the furnace door lifting mechanism; the furnace door lifting mechanism comprises a motor, drive sprockets and driven sprockets; the drive sprockets are respectively connected with both ends of an output shaft of the motor; the drive sprockets are respectively and mutually connected with the driven sprockets through chains; one ends of the chains are mutually connected with a balance hoisted weight arranged below the cross beam; the other ends of the chains are mutually connected with the upper end of the furnace door; the lower end of the furnace door is provided with a bulge; and the bulge is matched with a groove of a furnace mouth. According to the furnace door structure for the tunnel furnace, the furnace door is opened and closed by adopting a vertical lifting mode. The furnace door structure for the tunnel furnace not only is simple in structure and is easy to realize but also is good in seal effect.
Description
Technical field
The utility model relates to a kind of tunnel kiln, relates in particular to a kind of tunnel kiln and uses door structure.
Background technology
Door structure plays important effect for the sealing of tunnel kiln; The conventional tunnel kiln adopts and to be articulated and connected, and this structure owing to be articulated and connected is fixed, so fire door is when closing; The gap appears between fire door and the fire door easily; It is poorly sealed to cause fire door to close the back, and oven door sealing sternly can not produce very big negative effect for the performance of tunnel kiln, influences the quality of product in the stove.
The utility model content
The purpose of the utility model is to provide a kind of tunnel kiln to use door structure to the problems referred to above, closes gapped, the poorly sealed problem in back with the fire door that solves traditional tunnel kiln.
The purpose of the utility model is to realize through following technical scheme:
A kind of tunnel kiln is used door structure, comprises fire door and fire door elevating mechanism, and said fire door both sides are provided with support; Said support upper end is connected with crossbeam, and the fire door elevating mechanism is installed on the said crossbeam, and said fire door elevating mechanism comprises motor, drive sprocket and driven sprocket; The two ends of said motor output shaft all are connected with drive sprocket; Said drive sprocket is connected with corresponding driven sprocket respectively through chain, and an end of said chain is connected with the balance crane weight that is arranged on the crossbeam below, and the other end is connected with the upper end of fire door; The lower end of said fire door is provided with convexity, and the groove of said convexity and fire door is suitable.
Special, said fire door inboard is provided with reinforcement.
Special, on the said balance crane weight limit switch is installed.
The beneficial effect of the utility model does, said tunnel kiln adopts the vertical lift mode to open and close fire door with door structure, and is not only simple in structure, be easy to realize, and good sealing effect.
Description of drawings
According to accompanying drawing and embodiment the utility model is done further explain below.
Fig. 1 is the structural representation of the utility model tunnel kiln with door structure.
Among the figure:
1, support; 2, fire door; 3, chain; 4, crossbeam; 5, driven sprocket; 6, drive sprocket; 7, motor; 8, limit switch; 9, balance crane weight; 10, convexity.
The specific embodiment
Please with reference to shown in Figure 1, Fig. 1 is the structural representation of the utility model tunnel kiln with door structure; In present embodiment, a kind of tunnel kiln is used door structure, comprises fire door 2 and fire door elevating mechanism; Said fire door 2 both sides are provided with support 1; Said support 1 upper end is connected with crossbeam 4, on the said crossbeam 4 the fire door elevating mechanism is installed, and said fire door elevating mechanism comprises motor 7, drive sprocket 6 and driven sprocket 5; The two ends of said motor 7 output shafts all are connected with drive sprocket 6; Said drive sprocket 6 is connected with corresponding driven sprocket 5 respectively through chain 3, and an end of said chain 3 is connected with the balance crane weight 9 that is arranged on crossbeam 4 belows, and the other end is connected with the upper end of fire door 2; It is suitable with the groove of fire door that the lower end of said fire door 2 is provided with convexity 10, said protruding 10.
Special, said fire door 2 inboards are provided with reinforcement.
Special, on the said balance crane weight 9 limit switch 8 is installed.
During work, motor 7 drives drive sprocket 6 and rotates, and drive sprocket 6 drives driven sprocket 5; And the chain 3 that drives on it moves up and down, because chain 3 is connected with fire door 2 upper ends, thus the vertical lift of realization fire door 2; When fire door 2 lifting open or the process of closing that descends in because the weight of fire door 2 and balance lift heavy thing 9 is equal basically, make fire door 2 can rest in the up-down the optional position; When fire door 2 declines were closed, the convexity 10 of fire door 2 lower ends was inserted in the groove of fire doors, and fire door 2 is close to fire door; Above-mentioned tunnel kiln adopts the vertical lift mode to open and close fire door 2 with door structure, and is not only simple in structure, be easy to realize, and good sealing effect.
Claims (3)
1. a tunnel kiln is used door structure, comprises fire door and fire door elevating mechanism, it is characterized in that: said fire door both sides are provided with support; Said support upper end is connected with crossbeam, and the fire door elevating mechanism is installed on the said crossbeam, and said fire door elevating mechanism comprises motor, drive sprocket and driven sprocket; The two ends of said motor output shaft all are connected with drive sprocket; Said drive sprocket is connected with corresponding driven sprocket respectively through chain, and an end of said chain is connected with the balance crane weight that is arranged on the crossbeam below, and the other end is connected with the upper end of fire door; The lower end of said fire door is provided with convexity, and the groove of said convexity and fire door is suitable.
