Description
Technical field
The utility model belongs to dedusting field of explosion, more specifically to a kind of tobacco dedusting explosion-proof apparatus.
Background technique
Dust explosion refers to combustible dust within the scope of explosion limit, encounters heat source (open fire or high temperature), and flame moment passes
It is sowed at entire mixed dust space, forms very high temperature and very big pressure, there is very strong destructive power.The three of dust explosion
A condition:
1, combustible dust is suspended in air with concentration appropriate；
2, there are sufficient air and oxidant；
3, there are fire source or higher temperature；
A possibility that tobacco dust belongs to combustible dust, and there are dust explosions, tobacco dedusting air hose is for collecting conveying
The capital equipment of (wind energy conveying) tobacco dust can have a large amount of dust in equipment in-service pipeline, once reach condition
Dust explosion consequence is unimaginable.
Utility model content
The utility model is that the temperature controlled in pipeline combines dust concentration, it is ensured that temperature and dust in pipeline
Concentration be far smaller than dust explosion needed for temperature value.
To achieve the goals above, the utility model is achieved through the following technical solutions: the tobacco dedusting wind
Pipe explosion-proof apparatus includes Electric Actuator 1, control instrument 2, secondary air channel 3, temp probe 4, and the temp probe 4 is installed on dedusting
Inside air hose, 4 output end of temp probe is connect with control instrument 2, and 2 output end of control instrument is connect with Electric Actuator 1, electronic
Actuator 1 is installed on secondary air channel 3, and for opening or closing secondary air channel 3, secondary air channel 3 is connect with manufacturer's inner fan air outlet.
Preferably, the secondary air channel 3 and Electric Actuator 1 are installed on dedusting air hose by punching bolt.
Preferably, the temp probe 4 uses 18B20, and control instrument 2 uses SN-4KW micro-computer temperature control cabinet.
The utility model the utility model has the advantages that
The utility model is that the temperature controlled in pipeline combines dust concentration, it is ensured that temperature and dust in pipeline
Concentration be far smaller than dust explosion needed for temperature value, prevent from exploding.
Detailed description of the invention
Fig. 1 is the utility model structure chart；
In figure, 1- Electric Actuator, 2- control instrument, 3- secondary air channel, 4- temp probe.
Specific embodiment
Below in conjunction with the utility model embodiment and attached drawing, the technical scheme in the embodiment of the utility model is carried out clear
Chu is fully described by, it is clear that described embodiment is only the utility model a part of the embodiment, rather than whole implementation
Example.Based on the embodiments of the present invention, those of ordinary skill in the art are obtained without making creative work
The every other embodiment obtained, all category scope of protection of the utility model.
The tobacco dedusting air hose explosion-proof apparatus includes Electric Actuator 1, control instrument 2, secondary air channel 3, temp probe 4,
The temp probe 4 is installed on inside dedusting air hose, and 4 output end of temp probe is connect with control instrument 2, and control instrument 2 is defeated
Outlet is connect with Electric Actuator 1, and Electric Actuator 1 is installed on secondary air channel 3, for opening or closing secondary air channel 3, secondary air channel
3 connect with manufacturer inner fan air outlet.
The secondary air channel 3 and Electric Actuator 1 is installed on dedusting air hose by punching bolt.
The temp probe 4 uses 18B20, and control instrument 2 uses SN-4KW micro-computer temperature control cabinet.
Dedusting air hose explosion-proof apparatus cardinal principle is that the temperature controlled in pipeline combines dust concentration, it is ensured that in pipeline
Temperature and dust concentration be far smaller than dust explosion needed for temperature value.
Utility model works principle: dedusting air hose explosion-proof apparatus is by Electric Actuator 1, control instrument 2, secondary air channel 3 and temperature
4 composition of degree probe, temp probe 4 is mounted in air hose, Electric Actuator 1 and secondary air channel 3(DN150) punching is mounted on dedusting wind
Guan Shang, 1 output end of Electric Actuator are connect with the valve of secondary air channel 3.Temperature and soot density are in air hose when normal work
One relative constant value (30 DEG C), the steady state value set the setting value for mending wind cooling as 40 DEG C, when in air hose as working value
When soot density or temperature are changed more than 40 DEG C, Electric Actuator 1 can open wind-supplying mouth, to supplementing in dedusting air hose
Fresh air is to reduce temperature and soot density, so that it is guaranteed that the temperature in dedusting air hose is not achieved needed for dust explosion forever
Temperature value.
Finally, it is stated that preferred embodiment above is merely to illustrate the technical solution of utility model, although rather than limiting
The utility model is described in detail by above preferred embodiment, but it should be understood by those skilled in the art that can
To make various changes to it in the form and details, without departing from the protection scope of the utility model.
