Selection broken arch is installed Handling Precautions

      In a variety of coal storage warehouse, storage of coal due to moisture, the backlog of other reasons, can form different types of bagging clogging. In order to meet the

needs of a variety of situations, broken arch Selection and arrangement of positions should be based on the form of coal, capacity, cross-sectional area, discharge angle, stored

material nature, the environment, etc.

Conditions into account.
A principle of selection
(1) various volume broken arch device type: ① volume 70L or less broken arch is mainly used for dry coal, less impurities, good liquidity, coal storage capacity and the cross-

sectional area smaller occasions, such as: plastic chain conveyor coal preparation plant and so on. ② volume 70L, 170L between the broken arch is mainly used for storage of small general stores

Briquette positions. Such as: underground coal bunker transfer points and so on. ③ volume 170L, 300L between the broken arch, the main condition for the complex coal coal

storage, storage silo capacity and cross-sectional area is not too large, the flow conditions are poor and easily compacted compaction COAL BUNKER on. Such as: all kinds of

medium loading coal bunker, larger capacity

Coal storage, surge bin and so on. ④ volume 500L broken arch, mainly for large storage bunkers, such as: a large centralized coal storage capacity and so on.
(2) coal bunker meet the following situations, to use a larger volume of broken arch device.
 ① highly moist powder coal material; ② with large gangue, coal lump coal mixed material; ③ the consolidation of long-term storage of coal material; ④ bunker exit cone angle

flat or narrow;
(3) For the coal bunker with explosion-proof requirements of the broken arch device should be used in pneumatic or electric control type explosion-proof solenoid valve. I use

mine gas control type.
2 Installation Method
      Bunker structure  roller conveyor  analysis and field observations, in general, most likely bagging, blocked parts of the wall and the vertical position to the lower conical hopper

junction, so cloth emphasis should also be broken arch is in this range. For a variety of situations within easy camber angle at different levels by breaking the arch is

arranged a number of units,

Form a working operating system. In general, cloth broken arch device layer from 0.9 - 1.5 m, spaced about 5 meters staggered with. These are just general selection method. The

exact configuration of a bunker several, sub-layers shall be arranged according to specific circumstances.
      Broken arch uses flange connection, light weight, greater freedom for installation, use the rope hanging or bolted to the coal warehouse wall, can be placed on the

platform or the ground, as long as the safe, reliable, easy maintenance can be. Installation should try to find ways to reduce exhaust airflow resistance

, To reduce power consumption. Its exhaust port should be facing down, into the mouth to prevent the device sewage, debris affect the results. Broken arch drain plug on the

device body should also lower, to maximize the ejector body of water.
3 Operating System
      Broken arch the operation is very flexible and can be manual, pneumatic single control; regular automatic blasters and other control methods. When you first open the

manual valve operation, the gas will automatically enter device body requires blasting, click the Start button, an air signal to the valve. Broken arch device that

Powerful impact ejected through the vent airflow, automatic recovery after energy release inflated state, ready to complete the second work cycle.
4 Note Tong matters
      Broken arch is fully installed, after careful examination, no problem again broken arch is inflated and sealed inspection, after passing the test can be conducted sake of

making criticisms, the test can be used to put a lower pressure test, no problem then gradually rose to the maximum working pressure, safety qualified to be formally

Put into use.
