Embodiment Construction
[0019] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the words "inner" and "outer ” refer to directions toward or away from the geometric center of a particular part, respectively.
[0020] As shown in the figure, a negative pressure dust removal equipment includes a negative pressure chamber 1, a baffle 2, a partition 3, a differential pressure valve 6, and a filter bag 5. The baffle 2 separates the negative pressure chamber 1 into independent Negative pressure chamber, the partition board 3 divides the negative pressure chamber into two negative pressure a...

The invention discloses a negative pressure dedusting device. The negative pressure dedusting device comprises a negative pressure chamber, a baffle plate, separation plates, pressure differential valves and filter bags. The negative pressure chamber is divided into independent negative pressure capsules by the baffle plate. Each negative pressure capsule is equally divided into two negative pressure air channels by the separation plate. The pressure differential valves are arranged on the separation plates respectively. Each pressure differential valve has two air openings. The air openings are located in the negative pressure air channels at two sides. A movable cover is arranged on each air opening. The filter bag is arranged in the air channel, and the opening of the filter bag is located under the air channel. When the filter bag is blocked, the negative pressure increases, the cover is sucked into the air channel, and the cover is opened. If the covers at two sides are both opened, but certain differential pressure exists, air at one side with a low negative pressure value flows to one side with a high negative pressure value, air flow is formed, the filter bag is blown, the shape of the filter is changed, and thus dust falls off. Collected dust of the filter bags in adjacent air channels are cleaned at intervals through a negative pressure principle, labor and material resources are saved, the maintenance cost is saved, and the maintenance cycle is prolonged.
Description
technical field [0001] The invention belongs to the field of equipment dust removal, and in particular relates to negative pressure dust removal equipment. Background technique [0002] At present, the product collection silo usually uses negative pressure to suck the product material through the pipeline, and a filter bag is installed on the top of the silo to collect product dust. However, if the negative pressure works for a long time, the filter bag needs to be replaced and cleaned frequently, which is usually found manually. After the filter bag is clogged, it needs to be disassembled and cleaned or electronic equipment is needed for monitoring, which brings complicated maintenance and follow-up work, resulting in a waste of manpower and material resources. Contents of the invention [0003] In order to solve the above problems, the present invention discloses a negative pressure dedusting device, which is used to solve the problem of the negative pressure chamber. ...
