Description

Technical Field

[0001] The utility model belongs to the technical field of discharging devices, and in particular relates to a discharging device with an explosion-proof valve. Background Art

[0002] The existing calcining furnace is designed to be a high-capacity calcining furnace with a large discharge volume, high production capacity and high volatile matter. It is easy to have incomplete combustion of volatile matter, and the volatile matter moves down to the discharge system. At present, when the calcining furnace is in full load production, there is frequent blasting in the discharger system, resulting in damage to the seal at the sealing connection between the discharger and the lower water jacket and the discharge chute, and the conveyor soft connection canvas is broken due to blasting, resulting in poor sealing in various places and flying dust. Although the blasting is reduced by reducing the load production, it cannot meet the downstream production needs, and it is necessary to purchase calcined coke, which increases the production cost.

[0003] At present, the original factory did not design and install explosion-proof holes on the discharge chute of the discharge system, resulting in some internal pressure that cannot be released. This does not meet the production requirements of the calcining furnace and there are shortcomings in full-load production. Utility Model Content

[0004] The utility model aims to provide a discharging device with an explosion-proof valve. The explosion-proof valve is installed on the material chute of the discharging system to release the internal pressure, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a discharging device with an explosion-proof valve, comprising an explosion-proof steel pipe, which is generally inclined and whose bottom end is connected to a discharging chute with an inclined surface; an explosion-proof valve cover, which is arranged on the top of the explosion-proof steel pipe; an axial hinge, whose two ends are respectively fixed to the explosion-proof steel pipe and the explosion-proof valve cover; wherein the explosion-proof valve cover rotates around the axis of the axial hinge; the explosion-proof steel pipe, the explosion-proof valve cover and the axial hinge constitute an explosion-proof valve; and also includes a discharging chute, which is an isosceles trapezoid, and the explosion-proof valve is arranged on one of the side surfaces of the discharging chute, which is mainly used to realize discharging.

[0006] Preferably, the bottom end of the explosion-proof steel pipe is cut to form a slope, and the slope has the same inclination as the slope of the unloading chute.

[0007] Preferably, a notch equal to the inner diameter of the explosion-proof valve cover is opened on the side of the discharge chute, and the bottom end of the explosion-proof valve cover is welded and fixed to the discharge chute. In installing the explosion-proof valve on the discharge chute shell, the size is first measured to determine the installation position, and the discharge chute shell is cut by gas cutting to form a notch, and then electric welding is used to complete the installation of the explosion-proof valve on the discharge chute.

[0008] Preferably, the inner diameter of the explosion-proof valve cover is larger than the outer diameter of the explosion-proof steel pipe, so that the explosion-proof steel pipe can be better covered, and the top port of the explosion-proof steel pipe can be quickly and stably closed after the pressure is released. The explosion-proof valve cover and the center of the explosion-proof steel pipe are on the same straight line.

[0009] Preferably, a spring is fixed at the inner edge of the explosion-proof valve cover, and the spring is in contact with the top surface of the explosion-proof steel pipe. After the pressure relief is completed, the explosion-proof valve cover will fall due to gravity. At this time, the spring can be used for buffering to reduce the noise generated during use, and can also reduce the damage caused by the collision between the explosion-proof steel pipe and the explosion-proof valve cover.

[0010] Preferably, a polyester fiber sound-absorbing panel is further provided inside the explosion-proof valve cover, and a notch is provided at the surface edge of the polyester fiber sound-absorbing panel, and the spring is located in the notch, thereby reserving a placement space for the spring.

[0011] Preferably, screw holes are provided around the explosion-proof valve cover, and limiting bolts are screwed into at least two of the screw holes. The limiting bolts abut against the bottom end surface of the polyester fiber sound-absorbing board, thereby supporting the polyester fiber sound-absorbing board and preventing the polyester fiber sound-absorbing board from falling.
