A kind of explosion-proof detection opening device that is used for baking oven, it comprises combustible gas concentration detection apparatus, cylinder, pull bar, last gate stop and the following gate stop that matches with last gate stop, be provided with the combustible gas concentration detection apparatus in the baking oven, described combustible gas concentration detection apparatus connects cylinder, described cylinder links to each other with pull bar, be fixed with gate stop on the described pull bar, the described other end of going up gate stop is fixed on the baking oven doorframe by bearing pin, and described gate stop down is fixed on the oven door by bearing pin.
Detailed technical scheme is: a kind of explosion-proof detection opening device that is used for baking oven, it comprises the combustible gas concentration detection apparatus, cylinder, pull bar, last gate stop and the following gate stop that matches with last gate stop, be provided with the combustible gas concentration detection apparatus in the baking oven, described combustible gas concentration detection apparatus connects cylinder, described cylinder links to each other with pull bar, be fixed with gate stop on the described pull bar, the described other end of going up gate stop is fixed on the baking oven doorframe by bearing pin, described gate stop down is fixed on the oven door by bearing pin, the described gate stop lower end of going up is provided with U type draw-in groove, the draw-in groove position that go up on the gate stop relatively described gate stop down upper end is provided with U type block tongue, is provided with a deflecting roller between cylinder and pull bar, and the piston rod of cylinder links to each other with an end of steel wire, the other end cylinder lever connecting rod of described steel wire, following gate stop is provided with handle.
Than solution of the prior art, the utility model advantage is:
1. the combustible gas concentration detection apparatus taked of the utility model can detect the concentration in the baking oven in real time, when combustible gas excessive concentration in the baking oven reaches default early warning value, the combustible gas concentration detection apparatus sends the signal of telecommunication and triggers cylinder, cylinder pulling pull bar makes that gate stop is thrown off and door is opened up and down, whole process need not manually-operated, improves the security of baking oven;
The explosion-protection equipment that the utility model adopted simple in structure, with low cost, be easy to realize.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
