Description
Technical field
The utility model belongs to safety equipment field, more particularly, to a kind of nonflame bleeder.
Background technology
With the continuous enhancing of domestic enterprise's safe production awareness, the demand of nonflame bleeder is also constantly expanding, choosing
It is first demand of the pendulum in face of each attention safety in production enterprise with up-to-standard nonflame bleeder.It is simple under normal circumstances
More or less a variety of problems occur in single be used in series spark arrester and rupture disk, it is necessary to consider flame barrier
The various aspects of performance such as performance, efficiency of releasing and maintainability can just meet the standard of zero tolerance.
Chinese patent CN202079064U discloses a kind of anti-explosion separator, it is possible to achieve nonflame is released, and it includes cylinder
Shape cylinder, cylinder upper end are provided with flange gas outlet, and lower end is provided with air inlet, prevented inside cylindrical tube equipped with cellular arrangement
Quick-fried barrier filler, the anti-explosion blocking filler are copper or copper alloy, and it uses the anti-explosion blocking filler of cellular arrangement, may tool
Standby preferable flame barrier property, but when the obstructing instrument is applied to dust, the obstruction of anti-explosion blocking filler is easily caused, seriously
Efficiency of releasing is reduced, and when the device blocks, maintainable extreme difference.
It is indispensable that nonflame bleeder must take into account efficiency of releasing, flame barrier property and maintainability, three.For
Solve this problem, meet the needs of market and client, it is necessary to develop a kind of nonflame bleeder suitable for actual condition.
The content of the invention
The purpose of this utility model is exactly to provide a kind of nonflame the defects of overcoming above-mentioned prior art to exist and release
Device.
The purpose of this utility model can be achieved through the following technical solutions：
A kind of nonflame bleeder, for being connected to by protection equipment, including flame obstructing instrument, gasket seal and flat board
Dust rupture disk, described flame obstructing instrument include a body with entrance and exit, flame cleaning element are provided with body,
Described panel dust rupture disk is arranged on the porch of body, and gasket seal is arranged on entrance and the panel dust explosion of body
Between piece.
Preferably, described body, gasket seal and panel dust rupture disk are connected by fastening bolt, and tight by this
Fixing bolt is connected to by protection equipment.
Preferably, described body is the rectangular tubular structure in cross section, and entrance section goes out perpendicular to the axis of body
The axis of mouth section and body is obliquely installed in 30~60 ° of angles.
Preferably, described flame cleaning element is arranged on the wire netting in the support body including support body and multilayer, described
The outer shape of support body and the interior shape of body match, each layer wire netting is parallel with the outlet of body.
Preferably, the lateral wall of the port of export of support body is arranged with high-temperature resistant rubber sealing ring.
Preferably, described support body is fixedly connected with body by the bolt being located on this body sidewall.
Preferably, the exit of described body is provided with dismountable outlet flase floor.
Operation principle of the present utility model is：
In use, the nonflame bleeder is connected to by protection equipment, when dust concentration is exceeded simultaneously in protection equipment
When there is dodging quick-fried phenomenon, panel dust rupture disk explosion, to release immediately, caused flame is controlled in flame baffling device,
And superpressure medium can continue through flame baffling device and release.
One of necessary condition required for burning seeks to reach certain temperature, i.e. ignition point, and temperature is less than ignition point
When, burning will stop.According to this principle, as long as the temperature of combustible substance is dropped to below its ignition point, it is possible to prevent
The sprawling of flame.It will become some tiny flames after many thin channel of the flame by flame baffling device.Design
During flame cleaning element inside flame baffling device, then expand the contact area of tiny flame and conduit wall as far as possible, strengthen
Heat transfer, makes flame temperature drop to below ignition point, so as to prevent propagation of flame.
Compared with prior art, the utility model has the advantages that：
(1) by gasket seal and high-temperature resistant rubber sealing ring, it ensure that the sealing property of device.High-temperature resistant rubber seals
Circle is arranged on the port of export of support body, and this is in order at the consideration of durability, because by the effect of multiple layer metal net, discharge-end temperature
Than relatively low, high-temperature resistant rubber sealing ring is set in this place, durability is more preferable.
(2) axis of the outlet of body and body is obliquely installed in 30~60 ° of angles, can effectively be increased outlet and be cut
Face, so as to improve efficiency of releasing.
(3) it is each layer wire netting is parallel with the outlet of body, also increase the contact surface of release material and wire netting
Product, flame barrier property are more preferable.
(4) due to releasing medium during releasing, can be attached on flame cleaning element, therefore, by setting support body,
And flame cleaning element is arranged on support body, it is necessary to when cleaning, bolt and outlet flase floor are dismantled, from going out for body
Mouth takes out support body, maintainable good so as to easily be cleaned to it.
Brief description of the drawings
Fig. 1 is diagrammatic cross-section of the present utility model.
In figure, 1 is panel dust rupture disk, and 2 be gasket seal, and 31 be body, and 32 be support body, and 33 be wire netting, and 34 are
Flase floor is exported, 35 be high-temperature resistant rubber sealing ring, and 36 be bolt.
