Description

Movable weighing hopper trapping cover

Technical Field

The utility model relates to an environmental protection equipment technical field specifically is a remove weighing hopper entrapment cover.

Background

A movable weighing hopper is a common charging device in the metallurgical industry. A large amount of dust is generated in the blanking process and drifts in an operation area. Because the weighing hopper is movable and corresponds to a plurality of or dozens of bins, the operation range is large and unfixed.

The conventional dedusting scheme is to seal the entire blanking area. The dust removal of the scheme can not effectively prevent the dust from overflowing even if the operation space is too large and the air volume is large, and the internal operation environment is worse due to the airtight space.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a remove weighing hopper entrapment cover to solve the problem that provides among the background art.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a remove weighing hopper entrapment cover, includes the weighing hopper, sets up the last suction inlet entrapment cover in weighing hopper side top, sets up the last suction inlet branch pipe in last suction inlet entrapment cover top, sets up the lower suction port entrapment cover in the weighing hopper below, sets up the lower suction port branch pipe in lower suction port entrapment cover both sides, sets up fixed branch pipe, switching valve, the fixed house steward that removes in last suction inlet branch pipe, lower suction port branch pipe the place ahead.

As a preferred embodiment of the utility model, go up suction inlet dust removal branch pipe import with go up suction inlet entrapment cover open-top intercommunication, lower suction inlet dust removal branch pipe have two, respectively with lower suction inlet entrapment cover both sides side opening intercommunication, go up suction inlet branch pipe, the synthetic export of lower suction inlet branch pipe convergence, along with the removal of weighing hopper with fixed branch pipe butt joint.

As a preferred embodiment of the utility model, fixed branch is provided with a plurality ofly, fixed branch is through switching over valve and fixed dust removal house steward intercommunication.

As a preferred embodiment of the present invention, the weighing hopper is disposed on a hopper car.

As an optimized implementation manner of the utility model, the utility model also comprises a weighing hopper trolley track matched with the weighing hopper trolley.

Compared with the prior art, the utility model provides a remove weighing hopper entrapment cover possesses following beneficial effect:

this remove scale fill entrapment cover, install on the scale fill through the entrapment cover that removes dust, move along with the scale fill, guarantee the scale fill no matter operation can both realize good dust removal effect under which feed bin, no dust is escaped outward, the total two suction inlets of entrapment cover, there is a suction inlet above the scale fill, a dust removal when being used for the feed of upper portion feed bin to the scale fill, a suction inlet below the scale fill, a dust removal when being used for the scale fill to connect the feed of hopper to fork truck, the dirty gas of two suction inlets gets into the dust remover through the pipeline and handles, whole entrapment device and scale fill integrated design, when not influencing normal production, the amount of wind is little, the installed capacity is little, reduce the energy consumption, save the working costs, workman's operational environment has also been improved greatly in addition.

Detailed Description

In order to better understand the purpose, structure and function of the present invention, the following description will be made in detail with reference to the accompanying drawings.

As shown in fig. 1-3, the utility model provides a technical solution: a movable weighing hopper collecting cover comprises an upper suction port collecting cover 1, an upper suction port dedusting branch pipe 2, a lower suction port collecting cover 3, a lower suction port branch pipe 4, a fixed branch pipe 5, a switching valve 6 and a fixed dedusting main pipe 7, wherein the other end of the fixed dedusting main pipe 7 is connected with a deduster;

the movable weighing hopper 10 is arranged on the weighing hopper trolley 9 and can move on a weighing hopper trolley track 11 along with the weighing hopper trolley 9; the upper suction port collecting cover 1 is arranged above the side of the movable weighing hopper 10 and is used for dust removal when the upper storage bin 8 supplies materials to the movable weighing hopper 10, and the lower suction port collecting cover 3 is arranged below the movable weighing hopper 10 and is used for dust removal when the movable weighing hopper 10 supplies materials to the forklift receiving hopper; the upper suction port collecting cover 1, the upper suction port dedusting branch pipe 2, the lower suction port collecting cover 3 and the lower suction port branch pipe 4 can move along with the movable weighing hopper 10;

under the negative pressure state, when the movable weighing hopper 10 is positioned below the stock bin 8 to receive materials, the switching valve 6 corresponding to the stock bin 8 is opened, the switching valve 6 of the fixed branch pipe 5 corresponding to other stock bins 8 is closed at the same time, the dusty smoke enters the upper suction port branch pipe 2 and the lower suction port branch pipe 4 through the upper suction port trapping cover 1 and the lower suction port trapping cover 3, and enters the dust remover through the fixed branch pipe 5, the switching valve 6 and the fixed dust removal main pipe 7 after being gathered.
