DETAILED DESCRIPTION

[0027] Clearly and completely describe the technical scheme in the embodiments of the utility model with reference to the drawings in the embodiments of the utility model, obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0028] Embodiment: refer to Figures 1-4 The dust control device for powder spraying pipeline shown in the figure, including dust removal fan body 1, the output end of dust removal fan body 1 is installed with the dust collection box 2 of built-in filter structure, wherein, the filter structure adopts the existing conventional dust filter structure, for example, the conventional dust cloth bag, the end portion of dust collection box 2 away from dust removal fan body 1 is fixedly connected with transparent cover 3, the upper end of dust collection box 2 is detachably installed with sealing cover plate 4, which is convenient for dismounting and replacing the filter structure inside dust collection box 2.

[0029] Among them, the inner side of transparent cover 3 is installed with prompting mechanism, prompting mechanism includes prompting part 5, fixed frame 6 and elastic expansion piece 7, specifically, fixed frame 6 is installed on the inner wall of transparent cover 3, one end of elastic expansion piece 7 is fixed with fixed frame 6, the other end of elastic expansion piece 7 is connected with prompting part 5.

[0030] Through the cooperation of prompting part 5, elastic expansion piece 7 and transparent cover 3, when normal dust removal, the air permeability of filter structure is strong, the airflow through transparent cover 3 is large, at this time, prompting part 5 is affected by the large airflow and makes elastic expansion piece 7 in the stretched state, prompting part 5 is located on the side close to transparent cover 3 away from dust collection box 2; when the filter structure is used for a period of time, the airflow passing property is poor, the airflow passing is small, at this time, prompting part 5 moves to the side of dust collection box 2 under the action of the elastic force of elastic expansion piece 7, the operator can know the blocking condition of filter structure by observing the position of prompting part 5 inside transparent cover 3.

[0031] Among them, about elastic expansion piece 7, specifically, as shown in Figure 4 Elastic expansion piece 7 includes sleeve 71, square rod 72 and tension spring 73, one end of sleeve 71 is fixed with fixed frame 6, the other end of sleeve 71 is slidably sleeved on the outside of square rod 72, tension spring 73 is fixed between fixed frame 6 and square rod 72, prompting part 5 is connected to the end of square rod 72 away from sleeve 71, the end of square rod 72 close to fixed frame 6 is fixed with limit sliding block 74, the inside of sleeve 71 is provided with limit sliding groove 7101 slidably matched with limit sliding block 74, which can effectively prevent the tension spring 73 from overstretching when the airflow is too large.

[0032] The prompt member 5 is a fan blade structure, and is rotatably installed at the end of the square rod 72; when the air flow passes, the fan blade structure is driven to rotate, and the greater the air flow, the faster the fan blade structure rotates, and vice versa; the operator can also know the clogging condition of the filter structure by observing the rotating speed of the fan blade structure.

[0033] In order to prevent external sundries from entering the transparent cover 3 in the shutdown state to cause the rotating failure of the prompt member 5, a protective net 11 is installed at the end of the transparent cover 3 away from the dust collecting box 2.

[0034] In addition, the end of the transparent cover 3 close to the square rod 72 is fixed with a warning rod 8, a plurality of plectrums 10 are equidistantly fixed on the outer circumferential surface of the end of the sleeve 71 close to the prompt member 5, and the end of the warning rod 8 away from the prompt member 5 is fixed with a hemispherical block 9; when the filter structure is gradually clogged, the prompt member 5 moves to the side of the dust collecting box 2 under the elastic force of the elastic expansion member 7; the plectrum 10 rotating with the prompt member 5 is poked by the hemispherical block 9, and a sound is emitted to better prompt the operator.

[0035] In addition, the more serious the clogging of the filter structure, the closer the prompt member 5 to the dust collecting box 2; by arranging the plurality of plectrums 10 in multiple circles on the sleeve 71 and arranging the number of plectrums 10 close to the fixed frame 6 to be greater than the number of plectrums 10 close to the prompt member 5, the above arrangement can ensure that the frequency of the hemispherical block 9 poking the plectrum 10 is not too small as the clogging becomes more and more serious, thereby ensuring that the operator can successfully find out.

[0036] It should be further explained that the hemispherical block 9 will contact and poke the plectrum 10 in a short time to emit a sound when the dust control device starts and stops; since the time is short, the operator will not be misinformed.

[0037] The working principle of the utility model is as follows: when normal dust removal, the air permeability of the filter structure is relatively strong, the air flow passing through the transparent cover 3 is relatively large; at this time, the prompt member 5 is in a stretched state under the action of the relatively large air flow, the prompt member 5 is located on the side close to the transparent cover 3 away from the dust collecting box 2, and the hemispherical block 9 does not contact the plectrum 10 at this time.

[0038] When the filter structure is used for a period of time, the air flow passing property is poor, and the air flow passing through is small; at this time, the prompt member 5 moves to the side of the dust collecting box 2 under the elastic force of the elastic expansion member 7; the plectrum 10 rotating with the prompt member 5 is poked by the hemispherical block 9, and a sound is emitted to better prompt the operator.

[0039] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
