[0027] The bag-type dust collector device for preparing iron phosphate has the following advantages:

[0028] In the present application, by the arrangement of the continuous separation mechanism, when one separation inner box is blocked, the air inlet switching head slides on the switching mounting and communicates with another separation inner box, so that the gas can enter the separation inner box, and the dust cloth bag in the separation inner box continues to separate the gas. In addition, when the air inlet switching head is separated from one separation inner box, the separation inner box can be quickly depressurized, and the air inlet switching head moves through the adapter support to drive the dust removal switching plate to separate from the inner dust removal pipe, realizing the purpose of automatic dust removal. Through the design logic of double-zone cycle switching, it is ensured that the cloth bags in the two separation inner boxes can alternately filter and clean, the overall operation stability and reliability of the equipment are greatly improved, and the air inlet pipe is switched at the same time.

[0029] Further, in the present application, by the arrangement of the blocking switching mechanism, when the dust cloth bag in one separation inner box is blocked in a large area, the gas pressure in the separation inner box will quickly rise, pushing the high-pressure push plate to move, and then the switching rack moves to drive the switching gear to rotate, and the switching gear drives the rotating switching rod to rotate, realizing the switching of the air inlet switching head. The rising gas pressure generated by the cloth bag blockage is used as the driving source of the air inlet switching head, without the need for additional electric or pneumatic driving devices, which reduces the equipment manufacturing cost and operating energy consumption, and simplifies the equipment structure.

[0030] Further, in the present application, by the arrangement of the knocking separation mechanism, when the high-pressure push plate retracts, it pulls the linkage pull frame to move, so that the linkage pull frame drives multiple push-pull frames to move, and the push-pull frames drive multiple active extrusion plates to contact the passive push plate in turn. When the active extrusion plate extrudes the passive push plate, the passive push plate drives the reciprocating slider to move, so that the reciprocating slider drives the knocking separation plate to knock the dust cloth bag, and then the particles on the dust cloth bag are actively separated. In addition, when the active extrusion plate contacts the passive push plate in turn, the dust cloth bag is knocked multiple times, thereby ensuring the separation effect and being discharged through the inner dust removal pipe, realizing the purpose of automatic cleaning when the separation inner box is switched, and enabling the other separation inner box to continue switching when it is blocked, so that the dust collector body can continue to work, and then triggering the knocking separation mechanism simultaneously when the pressure relief action is performed, realizing the linkage efficient dust removal, which not only ensures complete pressure relief, but also timely removes the blocked dust on the surface of the cloth bag, improves the dust removal effect, and prolongs the service life of the cloth bag.

Figures 7-10 The bag filter dust collector device for preparing ferric phosphate provided in this embodiment of the invention further includes a striking separation mechanism 9, which is installed on a blockage switching mechanism 8 and is used to strike and remove dust from multiple dust collector bags 5.

[0061] Specifically, the impact separation mechanism 9 includes multiple impact separation plates 901, and multiple connecting seats 902 are installed inside the dust collector body 1. The multiple impact separation plates 901 are movably installed in the multiple connecting seats 902 respectively. It should be noted that, in this embodiment of the invention, when the dust collector bags 5 inside the separation inner box 703 are blocked, causing the high-pressure push plate 808 to retract, the multiple impact separation plates 901 are driven to repeatedly impact the multiple dust collector bags 5, thereby actively separating the particles on the dust collector bags 5.

[0063] More specifically, in this embodiment of the invention, a passive push plate 905 is movably mounted on the connecting seat 902, and the passive push plate 905 is mounted on the reciprocating slider 903. Furthermore, a linkage pull bracket 908 is mounted on the high-pressure push plate 808, and multiple push-pull brackets 906 are mounted on the linkage pull bracket 908, with multiple active squeezing plates 907 mounted on the push-pull brackets 906. It should be noted that in this embodiment of the invention, when the high-pressure push plate 808 retracts, it pulls the linkage pull bracket 908 to move, causing the linkage pull bracket 908 to move the multiple push-pull brackets 906. The movement of the push-pull brackets 906 causes the multiple active squeezing plates 907 to sequentially contact the passive push plate 905. When the active squeezing plate 907 squeezes the passive push plate 905, the passive push plate 905 causes the reciprocating slider 903 to move, and the reciprocating slider 903 causes the striking separation plate 901 to strike the dust collector bag 5, achieving the purpose of cleaning the dust collector bag 5 by striking.

[0064] In summary, the working principle of the bag filter device for preparing iron phosphate provided by the embodiment of the application is as follows:

[0065] When the gas enters into the dust collector body 1 through the gas inlet pipe 2, the gas first enters into a separation inner box 703, and then passes through the filtration of a plurality of dust removal cloth bags 5, so that the waste gas is discharged through the gas outlet pipe 4. In this process, the gas enters into the separation inner box 703 through the gas inlet pipe 2 and the gas inlet switching head 702. If the dust removal cloth bags 5 in the separation inner box 703 are blocked in a large area, the gas pressure in the separation inner box 703 will rapidly increase, thereby driving the high-pressure push plate 808 to move. The movement of the high-pressure push plate 808 drives the outer push sliding rod 809 to move, and causes the reset spring 810 to be stressed. Meanwhile, the movement of the outer push sliding rod 809 drives the wedge-shaped push block 805 to move, so that the wedge-shaped push block 805 is pressed to drive the switching column 804 to move. The movement of the switching column 804 drives the switching rack 803 to move. The switching rack 803 slides in the transverse movement limiting slot 806, and the movement of the switching rack 803 drives the switching gear 801 to rotate. The switching gear 801 drives the rotating switching rod 708 to rotate, and simultaneously drives the outer push-pull rod 813 to rotate and disengage from a positioning clamping groove 814. The outer push-pull rod 813 is pressed to be retracted into the outer push sliding groove 812, and the outer push spring 815 is stressed. Therefore, when the switching gear 801 rotates into another positioning clamping groove 814, the outer push-pull rod 813 is clamped in the other positioning clamping groove 814 under the resilience of the outer push spring 815, so that the position of the rotating switching rod 708 after rotation can be fixed, and thus the position of the gas inlet switching head 702 can be fixed.

[0066] Further, when the rotating switching rod 708 rotates, the switching driving shaft 710 drives the switching driving rod 709 to move, and the switching driving shaft 710 slides in the switching driving rod 709. The movement of the switching driving rod 709 drives the gas inlet switching head 702 to move, so that the gas inlet switching head 702 slides on the switching mounting frame 701, and is limited by the limiting baffle 707 after the gas inlet switching head 702 moves to the position, so that the gas inlet switching head 702 communicates with another separation inner box 703, and thus the gas can enter into the separation inner box 703, and the dust removal cloth bags 5 in the separation inner box 703 continue to separate the gas. In addition, when the gas inlet switching head 702 is separated from a separation inner box 703, the separation inner box 703 can be rapidly depressurized, and the gas inlet switching head 702 moves through the adapter support 711 to drive the dust removal switching plate 706 to be separated from the inner dust removal pipe 705, so that the dust removal is automatically realized.

[0067] Further, when the high-pressure push plate 808 retracts, the linkage pull frame 908 is pulled to move, so that the linkage pull frame 908 drives the plurality of push-pull frames 906 to move, and the movement of the push-pull frame 906 drives the plurality of active extrusion plates 907 to sequentially contact the passive push plate 905; when the active extrusion plate 907 extrudes the passive push plate 905, the passive push plate 905 drives the reciprocating slider 903 to move, and the reciprocating slider 903 drives the knocking separation plate 901 to knock the dust cloth bag 5, thereby actively separating the particles on the dust cloth bag 5; in addition, when the active extrusion plate 907 sequentially contacts the passive push plate 905, the dust cloth bag 5 is knocked multiple times to ensure the separation effect, and is discharged through the inner dust outlet pipe 705, so that the dust collector body 1 can continue to work when another separation inner box 703 is blocked.

[0068] The above merely describes the preferred embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can make equivalent replacements or changes to the technical solutions and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered by the protection scope of the present application.
