Abstract
The utility model relates to the technical field of safety protection equipment of explosive detection, and provides a safety protection device for an explosive brisance test. The safety protection device comprises an explosion chamber, wherein the explosion chamber adopts a cylindrical structure; an operation port is arranged on one side of the explosion chamber; a protection door is mounted at the operation port; a chimney is arranged at the top of the explosion chamber; and an exhaust fan is arranged at the upper part of the chimney. The closed explosion chamber is arranged, so that when the explosive brisance test is performed, an explosive explodes in the explosion chamber, four major dangers caused by explosive explosion are greatly reduced; and after the explosion, the exhaust fan is opened, so that gas produced after the explosion is exhausted rapidly, time required by emission of the gas produced after the explosion is greatly shortened, potential safety hazards are eliminated, and the test efficiency is improved.
Description
Technical field
The utility model relates to the safety protection equipment technical field of explosive detection, relates in particular to a kind of safety device of explosive brisance test.
Background technology
Brisance is one of important indicator of explosion properties, and it has objectively reflected the quality of explosive finished product.Explosive brisance is also one that in the explosion properties testing, must survey.
During the test explosive brisance, in general environment in the open, carry out, this certainly exists four harm greatly that explosive charge brings, and dust, vibrate noise, slungshot.For explosive production enterprise, the test of brisance is the work of normalization, and therefore, the safety device of inventing a kind of explosive brisance test just extremely is necessary.
The utility model content
The purpose of this utility model is to provide a kind of safety device of explosive brisance test, is intended to solve the problem of the potential safety hazard all caused in environment because of explosive brisance test of the prior art in the open.
The utility model is to realize like this, the safety device of explosive brisance test comprises explosion chamber, described explosion chamber is columnar structured, one side of described explosion chamber is provided with gathering hole, on described gathering hole, protective door is installed, the top of described explosion chamber is provided with chimney, and the top of described chimney is provided with vent fan.
As a kind of improved plan, the top of described chimney is provided with protective cover.
The safety device of the explosive brisance test that the utility model provides, because it is provided with the explosion chamber of sealing, when carrying out the explosive brisance test, explosive, in the explosion chamber implode, has lowered four harm greatly that explosive charge brings greatly.After blast, open vent fan, explosion gases is discharged rapidly, greatly shortened the gas that produces after the explosive charge and distributed the required time, not only eliminated potential safety hazard but also improved testing efficiency.
The accompanying drawing explanation
Fig. 1 is the structural representation front view of the safety device of the explosive brisance test that provides of the utility model;
Fig. 2 is the vertical view of Fig. 1;
In figure: 1-explosion chamber, 11-gathering hole, 2-protective door, 3-chimney, 4-vent fan, 5-protective cover.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
The safety device of the explosive brisance test that the utility model provides comprises explosion chamber, this explosion chamber is columnar structured, and a side of explosion chamber is provided with gathering hole, and protective door is installed on gathering hole, the top of explosion chamber is provided with chimney, and the top of chimney is provided with vent fan.
The structural representation of the safety device that the explosive brisance that Fig. 1 and Fig. 2 show the utility model jointly to be provided is tested, for convenience of explanation, this figure only provides the structure division relevant with the utility model.
The safety device of explosive brisance test comprises explosion chamber 1, and explosion chamber 1 is columnar structured, and a side of explosion chamber 1 is provided with gathering hole 11, and protective door 2 is installed on gathering hole 11, and the top of explosion chamber 1 is provided with chimney 3, and the top of chimney 3 is provided with vent fan 4.During the test explosive brisance, at first open protective door 2, by Explosive roll and after surveying detonator, lead block that brisance uses and installing by the assay method requirement, put into explosion chamber 1, close protective door 2, with firing, device detonates, after explosive charge, open vent fan 4 gas produced after explosive charge and the dust exploded are discharged, beat afterwards and make protective door 2, take out lead block, measure explosive brisance.Make explosive in explosion chamber 1 implode, not only greatly lowered four harm greatly that explosive charge brings, also greatly shortened the gas that produces after the explosive charge and distributed the required time, not only eliminated potential safety hazard but also improved testing efficiency.
In this embodiment, at the top of chimney 3, be provided with protective cover 5, can when sleety weather, prevent that rainwater from entering in explosion chamber 1, affects test effect.
The safety device of the explosive brisance test that the utility model provides, because it is provided with the explosion chamber of sealing, when carrying out the explosive brisance test, explosive, in the explosion chamber implode, has lowered four harm greatly that explosive charge brings greatly.After blast, open vent fan, explosion gases is discharged rapidly, greatly shortened the gas that produces after the explosive charge and distributed the required time, not only eliminated potential safety hazard but also improved testing efficiency.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
