Abstract
The invention provides a decompression dust remover for a stirring system, comprising a dust removing bag and a trapezoid member. The decompression dust remover is characterized in that the upper part of the dust removing bag is in a closed-top cylindrical shape, and the lower part thereof is in a conical shape with a downward opening; the dust removing bag is a big bag the opening of which faces downwards; the trapezoid member is made of iron sheet and arranged under the dust removing bag, one end with a small opening of the trapezoid member is connected with the opening of the dust removing bag, and the other end thereof is connected with two air pressure exhaust pipes. The decompression dust remover for the stirring system of the invention has the advantages of obtaining stable measuring value when a stirring machine works, achieving no dust overflow, ensuring accurate measurement, effectively controlling dust emission, and strengthening protection around a stirring station and working environment.
Description
Technical field
The present invention relates to a kind of dust arrester, specifically, is a kind of decompression dust remover for stirring system.
Background technology
Along with the development of society, people have the shortening construction period to the continuous growth of skyscraper, subway, tunnel pre-stress concrete goods demand, save cement, and the Commercial Concrete that can satisfy engineering property and quality requirement demonstrates extremely great vitality.Therefore, the quality control of construction-engineering project concrete also just becomes most important with management.But be the quality of control concrete in the concrete production process, the powder that is added must could add mixer after the filler weigher metering, filler weigher also can produce certain negative pressure when proportioning meter, as unreasonable eliminating, then cause the scale value drift, directly influence the accurate rate of filler weigher metering, thus the quality of influence control concrete; And in the concrete production process, the negative pressure that coarse aggregate and powder produce when throwing in mixer can a part of powder along with negative pressure emission outside mixer, environment is polluted.
Known diameter is that the cylindrical cloth bag depression dust-removing volume of the high 150CM of 50CM is too small, and the air pressure exit angle is unreasonable, and dust is piled up serious.Fig. 1 is the schematic diagram of the right-angle type air pressure exit angle of known technology.When mixer was worked, the negative pressure of generation was greater than the elimination ability of deduster self, the excessive flour dust overflow that causes of negative pressure.The stream pressure that produces when not satisfying mixer work directly influences the metering of electronic scale.Negative pressure is easily returned after being discharged to dust settling pocket in a large number, can not fully discharge, and causes weighing value drift instability, influences quality of concrete.Dust is piled up and excessive surrounding environment is caused has a strong impact on.
Therefore known stirring system depression dust-removing system exists above-mentioned all inconvenience and problem.
Summary of the invention
Purpose of the present invention is to propose a kind of decompression dust remover for stirring system that can reduce negative pressure again can dedusting.
For achieving the above object, technical solution of the present invention is:
A kind of decompression dust remover for stirring system comprises a dedusting bag and a trapezoid part, it is characterized in that:
The top of described dedusting bag is the cylindrical of top closure, and the bottom is the taper shape that Open Side Down, and described dedusting bag is a big pocket that sack is downward;
Described trapezoid part is to be made by iron sheet, is arranged on the below of described dedusting bag, and osculum one end of described trapezoid part is connected with the sack of described dedusting bag, and its other end is connected with two exhaust pressure pipelines.
Decompression dust remover for stirring system operation principle of the present invention: respectively get a circular hole at mixer with above the filler weigher, be connected on the pipeline that leads to the depression dust-removing device with the mechanism that is flexible coupling, when producing concrete, mixing the negative pressure that machine and filler weigher produce all is transported in the depression dust-removing device by pipeline, negative pressure is removed simultaneously, dust is back to the machine of mixing, and has solved dust and has leaked and the influence of negative pressure to Weighing system.
After adopting technique scheme, decompression dust remover for stirring system of the present invention has the following advantages:
1. the weighing value stabilization of electronic scale when mixer is worked, dust is not excessive, guarantees that metering is correct.
2. controlled the discharging of dust effectively, strengthened reaching the protection of working environment around the mixing plant.

Fig. 1 is the prior art constructions schematic diagram;
Fig. 2 is the left view of Fig. 1;
The structural representation front view of Fig. 3 one embodiment of the invention;
Fig. 4 is the left view of Fig. 3;
The structural representation of Fig. 5 another embodiment of the present invention.
Wherein: 1 dedusting bag, anti-rain chambers 2,3 filler weighers, 4 mixers, 5 trapezoid parts, 6 workbenches, 7 pipelines.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing thereof the present invention is illustrated further.
Now see also Fig. 3 and Fig. 4, the structural representation front view of Fig. 3 one embodiment of the invention, Fig. 4 are the left view of Fig. 3.As shown in the figure, the top of described dedusting bag 1 is the cylindrical of top closure, and the bottom is the taper shape that Open Side Down, and described dedusting bag is a big pocket that sack is downward;
Described trapezoid part 5 is to be made by iron sheet, is arranged on the below of described dedusting bag.Osculum one end of described trapezoid part is connected with the sack of described dedusting bag, and its other end is connected with two exhaust pressure pipelines 7.
The structural representation of Fig. 5 another embodiment of the present invention.As shown in the figure, described dedusting bag 1 is arranged in the anti-rain chamber 2, the top of dedusting bag 1 is connected, fixes by rope with the top of anti-rain chamber 2, and a circular hole is respectively got on the top of mixer 4 and filler weigher 3, and mechanism is connected on the exhaust pressure pipeline 7 that leads to the depression dust-removing device with being flexible coupling.One end of described trapezoid part 5 is connected with the sack of dedusting bag 1, and the other end is connected with exhaust pressure pipeline 7.When producing concrete, the negative pressure that mixer 4 and filler weigher 3 are produced all is transported in the depression dust-removing bag 1 by exhaust pressure pipeline 7, and negative pressure is removed simultaneously, and dust is back to mixer 4, has solved dust and has leaked and the influence of negative pressure to Weighing system.
Above embodiment is only for the usefulness that the present invention is described, but not limitation of the present invention, person skilled in the relevant technique under the situation that does not break away from the spirit and scope of the present invention, can also be made various conversion or variation.Therefore, all technical schemes that are equal to also should belong to category of the present invention, should be limited by each claim.
