Description
Technical field
The present invention relates to emulsion field, be specifically related to the explosion venting device of a kind of powdery emulsifying explosive substrate pump.
Background technology
Pumping procedure is requisite important component part in continuous emulsifying explosive production technique, is again the process being relatively prone to accidents in Emulsion Explosive Production.Pumping procedure inevitably produces certain mechanism to material medium, and research shows, emulsifying base is inevitably present the bubble produced because of mechanism in preparation process, and these are all preferably blasts " focus ".In pumping procedure, when running into severe friction, by high temperature, extrude, the mechanism such as collision time, then it may happen that blast.For forbidding that powdery emulsifying explosive substrate pump superpressure is run, equipment is installed and was installed venting of dust explosion sheet at its outlet conduit originally, and when manifold pressure reaches capacity, venting of dust explosion sheet ruptures, and substrate moment discharges.The explosion venting device of substrate pump in the market all lacks substrate when venting of dust explosion sheet ruptures and collects container, and owing to venting of dust explosion sheet moment ruptures, the substrate temperature of discharge is high, and be difficult to predict when eliminating, splash when substrate is discharged to ground and come, easily produce security incident, operator are damaged.
For eliminating potential potential safety hazard, making a shielding container with Thin Stainless Steel steel plate, bottom is detachable, is placed in venting of dust explosion sheet and issues, even if substrate is discharged, is also collected in this container, and easy cleaning.
After installation, field ground is clean,.
Summary of the invention
It is an object of the invention to provide the explosion venting device of a kind of powdery emulsifying explosive substrate pump, the explosion venting device of this substrate pump overcomes the deficiencies in the prior art, simple in construction, easy installation and removal, easy to clean, eliminates the potential injury to operator, safe and reliable.
For reaching above-mentioned purpose, the technical solution adopted for the present invention to solve the technical problems is: the explosion venting device of a kind of powdery emulsifying explosive substrate pump, including the pressure release assembly being arranged on powdery emulsifying explosive substrate pump, described pressure release assembly includes positive arch form venting of dust explosion sheet, the upper clamper installing positive arch form venting of dust explosion sheet and lower gripper, upper clamper and lower gripper are fixed by upper flange and lower flange, it is characterized in that: the explosion venting device of this substrate pump also includes the substrate collection assembly being arranged on below pressure release assembly；Described substrate collection assembly is made up of outer cylinder, the inner cylinder of upper and lower side opening, flange and hopper, it is tightly connected between upper end and the upper end of inner cylinder of described outer cylinder, the height of described inner cylinder is less than the height of outer cylinder, inner cylinder communicates with the inner chamber of outer cylinder, in the lower end of outer cylinder, hopper is installed, by Flange joint between described outer cylinder and hopper, described outer cylinder matches with the size shape of hopper, and the internal diameter of inner cylinder upper end is more than the diameter of pressure release assembly discharging opening.
Preferentially, the height of described inner cylinder be outer cylinder height 1/3 1/4.
In technique scheme, the substrate delivery side of pump end at conveying material installs venting of dust explosion sheet, and when pressure deviates setting value within a certain period of time, venting of dust explosion sheet is with regard to spalling, thus discharges the pressure in pump, it is to avoid the generation of accident；For eliminating potential potential safety hazard, in technical scheme, a substrate collection assembly is made with stainless-steel sheet, it is made up of upper and lower two parts, the hopper of bottom is detachable, it is placed in below venting of dust explosion sheet, when substrate is discharged, it is collected in this container, after installation, field ground is clean, and easy cleaning, additionally, in the substrate collection assembly of the present invention, inner cylinder it is provided with in outer cylinder, and the upper end of outer cylinder and inner cylinder seals, substrate is discharged in this device, barrier effect due to inner cylinder, effectively prevent substrate and be splashed to outside, eliminate the potential injury to operator, safety is greatly improved.
Accompanying drawing explanation
Fig. 1 is the structural representation of the explosion venting device of the present invention a kind of powdery emulsifying explosive substrate pump.
Detailed description of the invention
The explosion venting device of powdery emulsifying explosive substrate pump a kind of to the present invention with embodiment is described in further detail below in conjunction with the accompanying drawings.The accompanying drawing constituting the application is used for providing a further understanding of the present invention, and the schematic description and description of the present invention is used for explaining the present invention, is not intended that inappropriate limitation of the present invention.
As seen from Figure 1, the explosion venting device of a kind of powdery emulsifying explosive substrate pump of the present embodiment by the pressure release assembly being arranged on powdery emulsifying explosive substrate pump and is arranged on the substrate collection assembly below pressure release assembly and forms.Pressure release assembly includes positive arch form venting of dust explosion sheet 1, the upper clamper 2 installing positive arch form venting of dust explosion sheet 1 and lower gripper 3, upper clamper 2 and lower gripper 3 are fixed by upper flange 4 and lower flange 5, the charging aperture of pressure release assembly upper end communicates with powdery emulsifying explosive substrate pump, and its lower end is provided with discharging opening.In the present embodiment, substrate collection assembly is arranged on the lower section of pressure release assembly discharging opening, is made up of outer cylinder 6, the inner cylinder 7 of upper and lower side opening, flange 8 and hopper 9；Being tightly connected between upper end and the upper end of inner cylinder 7 of outer cylinder 6, the height of inner cylinder 7 is less than the height of outer cylinder 6, and in the present embodiment, the height of inner cylinder 7 is the 1/3 of the height of outer cylinder 6.Described inner cylinder 7 communicates with the inner chamber of outer cylinder 6, in the lower end of outer cylinder 6, hopper 9 is installed, being connected by flange 8 is fixing between outer cylinder 6 with hopper 9, outer cylinder 6 matches with the size shape of hopper 9, and the internal diameter of inner cylinder 7 upper end is more than the diameter of pressure release assembly discharging opening.In the present embodiment, outer cylinder 6, inner cylinder 7 and hopper 9 in substrate collection assembly are made by corrosion resistant plate.
