Abstract
The utility model discloses a dust removal device on a dry powder production line, which comprises a draft induced fan, an upper case, a middle case, a dust hopper and a pulse blowing device. The pulse blowing device consists of a blowing tube and a pulse electromagnetic valve, the electromagnetic valve is arranged above the blowing tube, the blowing tube is arranged in the upper case, a dust discharge hole is arranged below the dust hopper, the upper case and the middle case are sequentially arranged above the dust hopper from bottom to top, the lower end of the middle case is fixed on a support, an air inlet is arranged on a surface of the middle case, filter bags are arranged between the middle case and the upper case horizontally and equidistantly, spring frameworks are disposed in the filter bags, and the draft induced fan is fixed on the outer wall of the upper case. The dust removal device is high in dust removal efficiency, fine in effect and short in blowing period, can blow to remove dust in a continuous air supply state, has high dust removal frequency, and can keep the filter bags in fine ventilating states so as to increase filter air-speed relatively. Moreover, the dust removal device is low in cost, simple in structure and convenient for operation.
Description
Technical field
The utility model belongs to the environment-friendly engineering technical field, is specifically related to a kind of dry mash production line dust arrester.
Background technology
The device that is used for dedusting at present in this area is to adopt common sack cleaner mostly, this common sack cleaner effect when newly installing and using is also apparent in view, but after using a period of time, owing to do not have automatic dust removing apparatus after the dust of cloth bag has been filled, must adopt artificial ash disposal, therefore workload is bigger, but often ash-removal effect is undesirable, speed is slow and complex operation is complicated.
The utility model content
The purpose of this utility model is to address the above problem, and a kind of simple to operate, with low cost and dry mash production line dust arrester that ash-removal effect is fabulous is provided.
The technical solution of the utility model is: a kind of dry mash production line dust arrester, comprise air-introduced machine, upper box, middle casing, ash bucket, and pulse spraying equipment, it is characterized in that: described pulse spraying equipment is made up of winding-up pipe and impulse electromagnetic valve, impulse electromagnetic valve is arranged on winding-up pipe top, the winding-up pipe is arranged in the upper box, described ash bucket below is provided with dust inlet, the ash bucket top is disposed with upper box and middle casing from top to bottom, middle casing lower end is fixed on the support, middle tank surface has air inlet, horizontal spaced set has filter bag between middle casing and the upper box, be provided with the spring skeleton in the filter bag, described air-introduced machine is fixed on the outer wall of upper box.Described filter bag length, footpath are than being (15: 1)～(40: 1).Adopt bolting between casing and the support in described.Have the winding-up aperture of φ 10～φ 30mm on the described winding-up pipe.
Operation principle of the present utility model is: when the grieshoch on the filter bag reaches certain thickness, this moment the starting impulse magnetic valve, compressed air in the gas bag is by the aperture of impulse electromagnetic valve on the winding-up pipe, and eject the injection air-flow of one high speed and high pressure to Venturi tube, and form one and be equivalent to injection airflow volume induced draft doubly, together enter in the filter bag, in bag, form the pressure that is higher than normal condition, under this pressure effect, make to occur the moment malleation in the filter bag, sharply expand; Be wrapped in filter bag on the spring skeleton by the blow pressure blow-up, the dust layer on the filter bag just can deform, rupture and break away from filter cloth, decline landing with the piece bulk, meanwhile, the filter bag internal pressure is not stably to stay in certain normal value, but pressure jumps at the beginning, the filter bag rapid expanding; Owing to be out of shape the drum that rises fiercely, it is big that filter bag inner volume space becomes suddenly, and pressure descends again; And since the coming off of dust layer, the resistance step-down, and the tolerance that enters in the filter bag also increases thereupon, just can in the very brief time, form reciprocally " bulging, flat, drum " wave variation of filter bag, descend thereby influence filter bag top clean gas plenum chamber internal pressure, dust-contained airflow case internal pressure rises.Also producing simultaneously the pressure wave jointly changes.Make the dust releasing that is deposited on the filter bag outside like this, fall in the ash bucket, arrive the deashing purpose.Because the comprehensive function of this high acceleration, vibration and filter bag distortion, thereby reached very high cleaning efficiency.
The short-term winding-up process of the utility model puts on the inboard of filter bag with relative higher residual compression and the duration of pulse jet generally has only 0.1～0.2s, so this device cleaning efficiency height, effect is better, the winding-up time is very very brief again, it can carry out jetting deashing under the state of not blowing-out, the deashing number of times is frequent, thereby keep filter bag often to be in the high ventilation state, filtration velocity also can correspondingly improve; And this installation cost is cheap, and is simple in structure, easy to operate.

Among the figure: 1, air-introduced machine 2, upper box 3, middle casing 4, ash bucket 5, dust inlet 6, support 7, air inlet 8, filter bag 9, winding-up pipe 10, impulse electromagnetic valve
The specific embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is done furtherly, but protection domain of the present utility model is not limited in following embodiment.
As shown in Figure 1: a kind of dry mash production line dust arrester, comprise air-introduced machine 1, upper box 2, middle casing 3, ash bucket 4, and pulse spraying equipment, described pulse spraying equipment is made up of winding-up pipe 9 and impulse electromagnetic valve 10, impulse electromagnetic valve 10 is arranged on winding-up pipe 9 tops, have several apertures on the winding-up pipe 9, winding-up pipe 9 is arranged in the upper box 2, described ash bucket 4 belows are provided with dust inlet 5, ash bucket 4 tops are disposed with upper box 2 and middle casing 3 from top to bottom, middle casing 3 lower ends are adopted and are bolted on the support 6, middle casing 3 surfaces have air inlet 7, horizontal spaced set has filter bag 8 between middle casing 3 and the upper box 2, be provided with the spring skeleton in the filter bag 8, described air-introduced machine 1 is fixed on the outer wall of upper box 2.
Implement by technique scheme, according to the requirement of filtering air quantity, length is set, the footpath is than the filter bag plurality of rows that is (15: 1)～(40: 1), it is 110～200mm that present embodiment adopts diameter, the filter bag of the long 2～9m of bag, be provided with in the filter bag and inhale filter bag flat when the spring skeleton effectively prevents the negative pressure operation, the winding-up aperture that is installed on the winding-up pipe of air-purifying chamber is φ 10～φ 30mm, the winding-up pipe is aimed at the suitable for reading of every filter bag, so that compressed air blows to filter bag when suitable for reading by aperture, the inducing peripheral air enters and carries out deashing in the filter bag, like this each winding-up pipe 3～40m that can jet
2The filter bag area, 5～16 filter bags.If adopt good persuader also can suitably increase filter area and filter bag quantity.
