Abstract
The utility model embodiment discloses a kind of pulse control instrument, the pulse control instrument includes panel, shell and terminal box, the shell is explosion-proof casing, the terminal box is anti-explosion terminal box, the explosion-proof casing is Stainless Steel Shell, the panel is connected through a screw thread flange installation on the housing, and sealing ring is equipped under the threaded connection flange.The sealing ring is rubber seal.The utility model embodiment uses the explosion-proof casing of stainless steel, and terminal box uses anti-explosion terminal box, thus realizes that the integrated explosion proof system of pulse control instrument shell can greatly improve security performance in the working environment of pulsed jet cloth filter.
Description
Technical field
The utility model is related to pulse control instrument field more particularly to a kind of Pulse Width Controls with shell explosion prevention function
Instrument.
Background technology
In Grain Logistics System, grain transmission process will produce a large amount of dust, not only result in environmental pollution, but also
The danger of dust explosion can be caused, in order to prevent such dangerous generation, it can be by the powder of dust pelletizing system for the grain depot of transfer class
Dirt flows back, and warehouse can be recycled dust, then handles anyway, since existing equipment does not have substantially
Explosion prevention function does not have dust-proof anti-especially for the pulse control instrument that can lead to explosion due to not having Explosion-proof Design substantially
Quick-fried function, if there is gas or dust explosion, these pulse control instruments are often seriously destroyed, and influence to use.
Therefore, the prior art need to be further improved.
Invention content
In view of the above technical problems, the utility model embodiment provides a kind of pulse control instrument, solves existing pulse control
Instrument processed does not have the technical issues of shell explosion prevention function.
The utility model adopts the following technical solution：
A kind of pulse control instrument, the pulse control instrument include panel, shell and terminal box, and the shell is explosion-proof shell
Body, the terminal box are anti-explosion terminal box.
The pulse control instrument, wherein the explosion-proof casing is Stainless Steel Shell.
The pulse control instrument, wherein the panel is connected through a screw thread flange installation on the housing, the spiral shell
Sealing ring is installed under line connecting flange.
The pulse control instrument, wherein the sealing ring is rubber seal.
In the pulse control instrument technical solution that the utility model embodiment provides, the explosion-proof shell of stainless steel is used
Body, and terminal box uses anti-explosion terminal box, the integrated explosion proof system of pulse control instrument shell is thus realized, in bag pulse dedusting
In the working environment of device, security performance can be greatly improved.
Description of the drawings
Fig. 1 is the front view of pulse control instrument in the utility model embodiment.
Fig. 2 is the side view of pulse control instrument in the utility model embodiment.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those skilled in the art are obtained without creative efforts
The every other embodiment obtained, shall fall within the protection scope of the present invention.
It please refers to Fig.1 and Fig. 2, one embodiment of pulse control instrument, pulse control instrument, institute in the utility model embodiment
It includes panel 1, shell 2 and terminal box 5 to state pulse control instrument, and panel 1 is connected through a screw thread flange 4 and is fixed on shell 2, this reality
The shell 2 for applying example is explosion-proof casing, and Stainless Steel Shell specifically may be used, and terminal box 5 is anti-explosion terminal box.In this way, pulse control
Instrument processed has all carried out Explosion-proof Design on the whole, it is made integrally to have explosion prevention function, in the working environment of pulsed jet cloth filter,
Security performance can be greatly improved.
Meanwhile in order to realize that dust explosion protection function, the present embodiment are also equipped with sealing ring 3 in the case where being threadedly coupled flange 4.It is close
Seal 3 can be good at the infiltration for completely cutting off external dust, ensures pulse control instrument inner clean, plays dust explosion protection effect.
Preferably, the sealing ring 3 of the present embodiment be rubber seal, structure be it is O-shaped, certainly, sealing ring 3 limit to and
Rubber seal, other materials can realize sealing effect.
Above example is only to illustrate the technical solution of the utility model, rather than its limitations；Although with reference to aforementioned reality
Example is applied the utility model is described in detail, it will be understood by those of ordinary skill in the art that：It still can be to preceding
The technical solution recorded in each embodiment is stated to modify or equivalent replacement of some of the technical features；And these
Modification or replacement, the spirit and model of various embodiments of the utility model technical solution that it does not separate the essence of the corresponding technical solution
It encloses.
