Description

Deashing sack cleaner voluntarily

The utility model relates to a kind of deduster of filtered air dust.

In the prior art, sack cleaner is of a great variety, domestic representative have pulse bag type dust collector, rotary counter-blowing flat bag deduster, horizontal flat bag reversed bay-type deduster and downflow type flat bag filter etc., these dedusters all filter ash disposal with filter cloth, but when deashing, all need to use external force, for example vibration or beating make dust come off from the cloth bag inwall and enter ash bucket, so the dedusting inconvenience.

The purpose of this utility model is to provide a kind of and does not use external force and the sack cleaner of automatic ash removing.

The technical solution of the utility model is: it comprises the upper box that is connected with the inlet (dust contained gas), be used for the casing that vertical direction is provided with cloth bag, the ash bucket that is positioned at the cloth bag below, described cloth bag upper oral part is connected with upper box, and described cloth bag infraoral is connected with ash bucket; Bottom half is provided with discharge in described, and described discharge is connected with blast pipe; Be provided with the deashing pipe of rotatable end sealing in the described discharge, the other end of this deashing pipe is connected with pressure gas source; Have the air port on the casing in described, have air outlet on the wall of described deashing pipe, described air port in turn with the deashing pipe on air outlet, the inner chamber of discharge be connected.

The utility model compared with prior art has following advantage:

When the deashing pipe rotates, air port on the middle casing is communicated with deashing pipe, discharge in turn, when deashing Guan Yuzhong casing was communicated with by the air port, the air-flow that the deashing pipe blows out was flattened the cloth bag in the casing in this, in dust just can be automatically come off ash bucket below entering from the cloth bag inwall; And the air port on the middle casing is when being communicated with discharge, and cloth bag is in the dust removal by filtration state, so dust removal by filtration and deashing take turns to operate, and deashing is timely.

The utility model will be further described below in conjunction with drawings and Examples:

Accompanying drawing 1 is a structural front view of the present utility model; Wherein:

[1]. upper box; [2]. cloth bag; [3]. dividing plate; [4]. the air port; [5]. air outlet; [6]. motor; [7]. the deashing pipe; [8]. discharge; [9]. ash bucket; [10]. ash ejector; [11]. backwind tube; [12]. dedusting fan; [13]. blast pipe; [14]. middle casing.

Embodiment: referring to accompanying drawing, comprise the upper box [1] that is connected with the inlet (dust contained gas), be used for the casing [14] that vertical direction is provided with cloth bag [2], the ash bucket [9] that is positioned at cloth bag [2] below, described cloth bag [2] upper oral part is connected with upper box [1], and described cloth bag [2] infraoral is connected with ash bucket [9]; It is characterized in that: casing [14] bottom is provided with discharge [8] in described, and described discharge [8] is connected with blast pipe [13]; Be provided with the deashing pipe [7] of rotatable end sealing in the described discharge [8], the other end of this deashing pipe [7] is connected with pressure gas source; Have air port [4] on the casing [14] in described, have air outlet [5] on the wall of described deashing pipe [7], described air port [4] in turn with deashing pipe [7] on air outlet [5], the inner chamber of discharge [8] be connected.Be separated at least two case chambers with vertical dividing plate [3] in the casing [14] in described, each case chamber all is provided with air port [4], and described deashing pipe [7] is provided with the air outlet [5] identical with the number of case chamber.Be connected by backwind tube [11] between described deashing pipe [7] and the blast pipe [13].Rotating shaft is equipped with at the place, axle center of described deashing pipe [7], is connected with motor [6] in this rotating shaft.Each air outlet [5] on the described deashing pipe [7] staggers mutually.Be provided with dedusting fan [12] in the described blast pipe [13], the air inlet of this dedusting fan [12] is connected with discharge [8].An oral area of described backwind tube [11] is connected on the air outlet place of the dedusting fan [12] of blast pipe [13].

During work, dust laden air is entered in the upper box [1] by blast pipe, diffusion profile is in each cloth bag [2] then, through the cloth bag filtration, concentrate on cleaned air in the middle casing [14] through the air port [4] and discharge [8], enter atmosphere by dedusting fan [12] and blast pipe [13], thereby finish whole purification process.The upper and lower port of cloth bag [2] is opened, and during dust releasing on adhering to cloth bag [2] inwall, dust can fall in the ash bucket [9] from the end opening of cloth bag [2] because of deadweight, and drains into the deduster outside through screw machine [10] or other ash exhauster.Start dedusting fan [12] and deashing pipe motor [6], then deashing pipe [7] and top air outlet [5] thereof will rotate in discharge [8], when air outlet [5] is aimed at air port [4], the malleation wind of being discharged by dedusting fan [12] will in backwind tube [11], deashing pipe [7], air outlet [5], air port [4] enter accordingly in the casing [14], shrivel cloth bag [2] thereby form buffer brake.When air port [4] was left in air outlet [5] rotation, this raising middle flask chamber [14] was connected with discharge [8] again, is in the dedusting state again.So constantly rotation of deashing pipe [7], then cloth bag [2] just is in dedusting, deashing, dedusting, deashing ... in the running status of going round and beginning again.The middle casing [14] on the left side shown in the figure is at deashing, and casing in the right [14] is in dedusting work.
