Description

Sack cleaner

The utility model relates to a kind of environmental protection equipment, and specifically a kind of each cloth bag can take out separately, and the deduster of rapping rod is set in cloth bag.

In the dust pelletizing system of the coal handling system in thermal power plant, boiler, thickness powder piece-rate system, all there is the problem of dust polluting environment to some extent, the mankind's physical and mental health is caused very big injury.For this reason, people have designed various dedusters, and are so that eliminate these dust, wherein commonly used with sack cleaner especially.

The operation principle of sack cleaner is the suction that utilizes centrifugal fan to produce, dust-contained airflow is collected dirt pocket, at dirt pocket the orderly cloth bag filter screen of arrangement is arranged, when dust-contained airflow rises, dust is wherein blocked by cloth bag, clean air enters in the cloth bag through between the cloth bag fabric, drains in the atmosphere again, reaches the purpose of dedusting.

But because existing these deduster structures are unreasonable, its result of use is unsatisfactory.Conclude get up mainly to exist following some: 1, do not have the rapping rod in the cloth bag, after operation a period of time, amass dust at the cloth bag outer wall and can stop up gap between the cloth bag fabric, influence passing through smoothly of air-flow, maintenance workload is increased, and make motor and the long-term overload operation of fan, shorten its service life; Secondly in the wall, it was inhomogeneous to conduct heat around heater was installed in, long-time heating, and heater strip blows easily, and as untimely replacing, Shi dust is bonded on the cloth bag excessively, and easy-clear performs practically no function its heating facility; The 3rd, owing to do not have the primary filter net at the inlet of cloth bag, foreign material such as the cloth sheet of carrying secretly in the air-flow, plastic tape are adsorbed to the cloth bag surface, influence dust removing effects, can't remove again; The 4th, the cloth bag constructions is a monolithic construction, just must change all cloth bags in the time of changing certain sheet cloth bag, both bothers, and influences normal dedusting again.

The purpose of this utility model is a kind of rational in infrastructure, replacing of design and sack cleaner easy to maintenance, good dedusting effect.

Its main technical schemes comprises wind sucting chamber and dirt pocket, uniform cloth bag in dirt pocket, it is characterized in that in the dirt pocket whole cloth bag by one by one mutually discrete cloth bag combine, the V-shape that the cross section of each cloth bag is all big up and small down, this shape both can increase the flow section of cloth bag, and the dust that is bonded on the cloth bag wall is dropped; A fixed frame that has slot is arranged in the top, at one group of fixed mount that has slot of the upper end of dirt pocket inner wall even distribution, and, each fixed frame inserts one by one in the fixed mount accordingly, when needs are changed certain cloth bag, one of them cloth bag extraction is got final product, more convenient; One vibration body that can impact the cloth bag wall is respectively arranged in the lower end of each cloth bag, the upper end of each vibration body extends the middle part of cloth bag, the shape of vibration body can be rectangular frame component, it also can be its horizontal respectively I-shaped in both sides up and down, one transportable installing rack is arranged in dirt pocket, uniform groove on installing rack, the bottom of cloth bag lays respectively in the groove, the drive installation frame, just can drive cloth bag bottom and vibration body thereof and move together, the upper end of vibration body be produced rock and impact cloth bag; One horizontally disposed snakelike infrared heating pipe is arranged below dirt pocket,, make it be easy to when the vibration beating cloth bag, drop, remove from the cloth bag wall so that heating is bonded at the dust on the cloth bag; Air inlet place in the deduster bottom is provided with anti-network blocking, so that remove some bigger fabric fibres and plastics class foreign material, in order to avoid these foreign material are adsorbed on the cloth bag wall, influences dust removing effects; In the bottom of deduster the dodge gate of being made up of geometrical clamp, coupling shaft and lock dirt door is set, when needing heating, promptly closes this dodge gate, in order to avoid moist air stream enters, influence adds thermal effect; There is the air compartment that is positioned at the wind sucting chamber bottom in wind sucting chamber on be positioned at dirt pocket and is positioned at the blower fan on wind sucting chamber top, the air inlet of blower fan is communicated with air compartment and dirt pocket, the dividing plate of band bloop is set in the sidewall outer of blower fan, filling glass silk between the shell of dividing plate and wind sucting chamber is to abate the noise.

Outstanding advantage of the present utility model is to be convenient to replacing and to safeguard, because each cloth bag is all separate, when finding which cloth bag need be changed, this cloth bag extraction is got final product, and need not change whole cloth bag, and both handled easily was saved material again; Secondly, in cloth bag, vibration body is set after, help removing the dust on cloth bag surface, increase work efficiency, or the like.
