Abstract

The utility model relates to a chambered inverse aspiration pocket type ash separator, which is applicable for smoke and dust treatment in metallurgy, cement, power generation, heat supply and other industries, belonging to environmental conservation equipment technical field. The chambered inverse air draught pocket type ash separator mainly comprises an upper box body, a flue-dust retainer, an air inlet, a discharge pipe, a inverse aspiration channel, more than one reversing service composed of a discharge valve and a inverse aspiration valve, a inverse aspiration control valve, an access door and an ash exhauster. The upper box body is provided inside with a dust filtration chamber which is provided inside with a filter bag, the upper portion of the filter bag is fixed on a sealing plate through a suspension linkage, and the lower portion of the filter bag is fixed on a figure pattern card through a bar clasp. The chambered inverse aspiration pocket type ash separator is mainly characterized in that the upper box body employs square structure, the air inlet is opened on one side of the flue-dust retainer, the reversing services are arranged in straight line shape, which makes the dust filtration chamber in the box body have more available volume, with simple manufacture, convenient installment and transportation. The chambered inverse aspiration pocket type ash separator is more convenient for maximization and product forming of a dust-cleaning apparatus, with lower running cost.

Description

Locellus back suction wind sleeve formula deduster

Technical field: the utility model relates to a kind of sack cleaner, is used for flue dust, the treating flour dust of industries such as metallurgy, cement, generating, heat supply, belongs to the environment protection equipment technical field.

Background technology: existing back suction wind sleeve formula deduster, its upper box shape mostly is circular, intake method is last air intake or tangential up and down air intake mode, exhaust and back suction wind switching device shifter are multiangular and arrange, said structure only is applicable to small-sized cleaner, be not easy to maximization, the commercialization of cleaner, make troubles for making, install, transporting, and operating cost be higher.

Summary of the invention: the purpose of this utility model is to overcome above-mentioned shortcoming and defect part, provides a kind of manufacturing simple, installation, convenient transportation, and operating cost is low, is convenient to the maximization of cleaner, the back suction wind sleeve formula deduster of commercialization.

Main solution of the present utility model is achieved in that it mainly comprises upper box, flue-dust retainer, air inlet, blast pipe, back suction airduct, the switching device shifter of being made up of air bleeding valve and back suction air-valve more than, back suction wind control valve, access door, ash exhauster, be provided with dust chamber in the upper box, filter bag is arranged in the dust chamber, filter bag top is fixed on the sealing plate by suspension arrangement, the bottom is fixed on the card with clip, is characterized in: upper box adopts square structure; Air inlet is opened the side in flue-dust retainer; It is arranged in a straight line that switching device shifter is " one " font.

Because employing said structure characteristics make the available volume of the interior dust chamber of casing increase, manufacturing is simple, installation, convenient transportation, and the maximization of the cleaner of being more convenient for, commercialization, and operating cost is lower.

Description of drawings: the utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is structure of the present utility model and working state schematic representation;

Fig. 2 is the utility model filter bag suspension arrangement structural representation;

Fig. 3 is the utility model plan structure schematic diagram;

Fig. 4 is a back suction wind control principle schematic diagram of the present utility model.

The specific embodiment: as shown in the figure, upper box 12, the flue-dust retainer 3 made by metal material are arranged on the support, upper box 12 tops do not have access door, but access door 21 is arranged on the side of upper box 12, can make so the disposable installation of fixing hoop under filter bag 5, suspension arrangement 7 and the filter bag is installed, make Operation and maintenance more quick.Suspension arrangement 7 be with interior filter bag 5 tops that keel 6 are arranged with spring 19 and link up with 18 and fixedly be fixed on the sealing plate 20, in the time of can making back suction wind deashing so good vibratility is arranged, ash-removal effect is better, the bottom is fixed on the card 13 with clip.Upper box 12 is a square structure, can be divided into some separate unit in the upper box 12 as required as dust chamber 4, and the casing volume is big more certainly, and open ended dust chamber is also many more.Some filter bags 5 are arranged in each dust chamber 4, each dust chamber's 4 corresponding row's air draught switching device shifter 26, each switching device shifter 26 comprises an air bleeding valve 8 and a back suction air-valve 10, directly links to each other with back suction airduct 9 with blast pipe 11 by them, and does not need to establish in addition air-purifying chamber.As shown in Figure 3, it is arranged in a straight line to be " one " font between a plurality of switching device shifters.

This deduster is the bottom air inlet, air inlet 2 is opened in the middle and lower part of flue-dust retainer 3 one sides, dusty gas enters deduster air inlet 2 through process pipeline, enter flue-dust retainer 3 tops through deflector 1 by the bottom, the part bulky grain is because inertia is fallen below the flue-dust retainer 3, and all the other dusty gases enter filter bag 5, and the gas after the filtration directly enters dust chamber 4, by air bleeding valve 8, blast pipe 11, control valve 16, enter atmosphere then by blower fan 17.Deashing is after deduster moves a period of time, and when filter bag 5 inner surfaces capture dust resistance reached certain value, PLC control system control back suction wind control device was promptly by back suction wind control valve 22 control switching device shifters 26.As shown in Figure 4, under the effect of electric pushrod 23, adjustment screw mandrel 24, connecting rod 25, self-timing is opened back suction air-valve 10, close air bleeding valve 8 simultaneously, originally the filter bag 5 that expands is inhaled flat distortion, vibration under the back suction wind action, make it reach the purpose that filter bag 5 inner surface dust are eliminated, make this chamber filter bag drop into operate as normal again, and, finish whole deduster deashing process successively to next dust chamber deashing.The dust of disposing falls into flue-dust retainer 3, gets rid of through conveying worm 14 reamers and separation wheel 15 blanking devices, is transported to the appointed place.
