Described heating tube body, comprises the air inlet near heating tube body bottom, near the gas outlet of heating tube body upper end, is built in the heating tube in heating tube body, heating tube fixed head and netted inner bag;
Described heating tube, is built-in with heater strip and is filled in the insulating materials around heater strip;
Described heating tube fixed head, be oblate column, the axis along described heating tube is uniformly distributed, quantity be two and more than, it has through hole, and described heating tube passes in described through hole, and the outer wall of described heating tube is fixedly connected with the inwall of described through hole respectively;
Described netted inner bag is hollow, and for cylindric, the axis along described heating tube is uniformly distributed, and surrounds described heating tube, and its lower edges is fixedly connected with respectively with corresponding heating tube fixed head, and its sidewall is distributed with mesh.
Further, described heating tube fixed head is fixedly connected with mode with described heating tube, and the lower edges of described netted inner bag respectively be fixedly connected with mode with corresponding heating tube fixed head and be and weld.
Further, described netted inner bag, its quantity be one and more than.
Further, described netted inner bag, the mesh that its sidewall distributes is that direction is consistent.
The advantage that the present invention has and good effect are:
Because the present invention adopts as above technical scheme, i.e. a kind of anti-explosion heater, comprises junction block and heating tube body; Described junction block, is built-in with connection circuitry, also comprises upper flange and lower flange, and junction block connects with the control cabinet of anti-explosion heater by described upper flange, and junction block connects with heating tube body by described lower flange; Described heating tube body, comprises the air inlet near heating tube body bottom, near the gas outlet of heating tube body upper end, is built in the heating tube in heating tube body, heating tube fixed head and netted inner bag; Described heating tube, is built-in with heater strip and is filled in the insulating materials around heater strip; Described heating tube fixed head, be oblate column, the axis along described heating tube is uniformly distributed, quantity be two and more than, it has through hole, and described heating tube passes in described through hole, and the outer wall of described heating tube is fixedly connected with the inwall of described through hole respectively; Described netted inner bag is hollow, and for cylindric, the axis along described heating tube is uniformly distributed, and surrounds described heating tube, and its lower edges is fixedly connected with respectively with corresponding heating tube fixed head, and its sidewall is distributed with mesh.
In the process that reality uses, when air stream is after the air inlet near heating tube body bottom enters heating tube body, it can produce motion upwards under the effect of the pressure, next will contact with described heating tube, because described heating tube is surrounded by described netted inner bag, the air force and velocity of a current must come in contact with netted inner bag, and then partial air flow will pass through the mesh that on described netted inner bag, direction is consistent, so just can increase the contact area of air stream and heating tube, improve the efficiency of heating surface of air, described mesh can be planned the path of air stream, and then keep the movement velocity of air-flow.
