Description

Technical Field

[0001] The utility model relates to the technical field of flameless explosion venting, in particular to a novel flameless explosion venting device. Background Art

[0002] When the flameless explosion venting device operates normally, the explosion venting plate is in a closed state. Once a dust explosion occurs inside the device, the acting force of the explosion overpressure on the explosion venting plate exceeds the opening pressure of the explosion venting plate, and the explosion venting plate will break and open along the seam. The explosion pressure will leak out from the gaps of the flame arrestor net, and the flame will be quenched by the "quenching" effect of the flame extinguishing layer to prevent the explosion pressure and the high temperature generated by the flame from causing harm to surrounding personnel or equipment.

[0003] However, there are some deficiencies in the current flameless explosion venting devices. When the flameless explosion venting device is not in use, there is no protection device at its upper end, which is not conducive to the protection of the flame arrestor net. And when the flameless explosion venting device is in use, the direction of the gas ejected inside it cannot be adjusted as needed. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a novel flameless explosion venting device, which can effectively solve the problems in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A novel flameless explosion venting device, including a device main body, an adjusting frame and an arc-shaped guiding plate. The two side surfaces of the device main body are fixedly installed with the adjusting frame. The front surface of the adjusting frame is movably installed with a support rod. The upper surface of the support rod is movably installed with a clamping block. The arc-shaped guiding plates are movably installed on the upper surface of the device main body and close to both ends.

[0007] Preferably, a lifting groove is longitudinally opened on the front surface of the adjusting frame. The lower surface of the adjusting frame is fixedly installed with an adjusting motor. The output end of the adjusting motor is fixedly installed with a threaded rod, and the upper end of the threaded rod extends into the lifting groove.

[0008] Preferably, a baffle is fixedly installed on the upper surface of the front end of the arc-shaped guiding plate. The rear surfaces on both sides of the baffle are fixedly installed with locking blocks. The lower surface of the front end of the arc-shaped guiding plate and close to both sides are fixedly installed with limiting sliding blocks.

[0009] Preferably, a threaded sleeve block is fixedly installed on the rear surface of the lower end of the support rod. A moving groove is opened on the upper surface of the support rod. A guide rod is fixedly installed inside the moving groove, and a spring is sleeved on the surface of the guide rod.

[0010] Preferably, a sleeve groove is opened on the front surface of the clamping block. Card slots are opened on the two side surfaces inside the sleeve groove. A sliding sleeve is fixedly installed on the lower surface of the clamping block.

[0011] Preferably, limiting sliding grooves are formed in the upper surfaces on both sides of the device main body, the limiting sliders are embedded in the limiting sliding grooves, and the threaded sleeve blocks are sleeved on the surfaces of the threaded rods inside the lifting grooves.

[0012] Preferably, the sliding sleeve is sleeved on the surface of the guide rod, the locking blocks are embedded in the clamping grooves, and the arc-shaped guide plates are movably connected to the device main body through the limiting sliders.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] In the utility model, by arranging the adjusting frame, the arc-shaped guide plates, the support rods and the clamping blocks to cooperate with each other, when the arc-shaped guide plates are not in use, the upper end of the device main body can be shielded and protected by the arc-shaped guide plates. When the flameless explosion venting device is in use, the two arc-shaped guide plates are spliced together. During the movement of the arc-shaped guide plates, the clamping blocks are pulled to both sides. After the two arc-shaped guide plates are spliced together, the external force for pulling the clamping blocks is released, so that the locking blocks of the arc-shaped guide plates are embedded in the clamping grooves. The adjusting motor of the adjusting frame is started by an external device, the adjusting motor controls the threaded rod to rotate, the rotating threaded rod controls the support rod to rise. As the support rod continuously rises, the clamping blocks will drive the two arc-shaped guide plates to rise simultaneously until the arc-shaped guide plates rise to the specified height. When the flameless explosion venting device sprays out, the gas changes the spraying direction under the action of the arc-shaped guide plates. BRIEF DESCRIPTION OF THE DRAWINGS
