[0003] The bag-type pulse dust collector is mainly composed of a box body, a filtration system and a blowing system. The filtration system mainly includes filter bags and bag cages. The filter bags are used to filter dust and other impurities in the gas. After the pulse dust collector has been working for a period of time, the dust on the surface of the filter bags continues to increase, causing the equipment resistance to increase.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] Embodiment 1

[0035] like Figure 1-8 As shown, a pulse dust collector according to an embodiment of the present invention comprises a housing 1, a filtering mechanism, a pulse spraying mechanism 3 and an ash discharge mechanism 4, wherein the housing 1 is provided with an air inlet 11 and an air outlet 12, wherein the filtering mechanism comprises a plurality of filter bags 2 arranged in the housing 1, wherein the plurality of filter bags 2 are arranged in a rectangular shape, wherein the pulse spraying mechanism 3 is used for pulse spraying and cleaning the filter bags 2, wherein the gas to be treated enters the housing 1 through the air inlet 11, and the impurities in the gas are filtered by the filter bags 2 and fall into the ash discharge mechanism 4, and the filtered gas is discharged from the housing 1 through the air outlet 12, and the ash discharge mechanism 4 is used for discharging the impurities from the housing 1; and further comprises a plurality of isolation mechanisms 5 and a control mechanism 6 arranged in a rectangular shape;

[0036] The isolation mechanism 5 is arranged between two adjacent rows of filter bags 2, and the isolation mechanism 5 comprises: a fixed enclosure 51 fixedly connected to the inside of the box body 1; two movable enclosures 52 respectively arranged on both sides of the fixed enclosure 51; after the fixed enclosures 51 on both sides of a single filter bag 2 rotate in the opposite direction, the two groups of fixed enclosures 51 and the movable plates form an enclosure structure and cover the outside of the filter bag 2;

[0037] The control mechanism 6 is used to control the movement of the movable enclosure 52 .

[0038] Specifically, the box body 1, the filtering mechanism, the pulse dust removal mechanism and the dust unloading structure adopt the relevant structures in the existing pulse bag dust collector. The filter bag 2 is made of filtering material, such as polyester fiber, glass fiber, PPS polyphenylene sulfide, etc. The filtering mechanism also includes a plurality of bag cages arranged inside the box body 1. The bag cages are used to support the filter bag 2 so that it maintains its shape during the filtering process.

[0039] The pulse spray system includes a pulse valve, a spray pipe and an air bag. The air bag is used to provide an air source, and the pulse valve is used to control the high-pressure air in the air bag to be sprayed into the filter bag 2 via the spray pipe; the pulse valve is used to receive the signal of the control unit in the dust collector, open and close at appropriate times, and spray high-pressure air into the filter bag 2 to remove the dust accumulated on the filter bag 2; the spray pipe is connected to the pulse valve to spray the high-pressure air evenly to each filter bag 2, and the spray pipe is provided with spray holes, and the number and position of the spray holes are designed according to the arrangement of the filter bag 2 to ensure that each filter bag 2 can be effectively cleaned; the air bag is used to store high-pressure air to provide a stable air source for the pulse valve.

[0040] The ash unloading mechanism 4 includes an ash hopper and a discharger. The ash hopper is arranged at the bottom end of the box body 1 . The discharger is used to discharge impurities in the ash hopper to the outside of the box body 1 .

[0041] Initially, the states of the fixed panel 51 and the movable panel 52 are as follows: Figure 2 and Figure 6 As shown, the fixed enclosure 51 and the movable enclosure 52 are straight and do not surround the filter bag 2. The airflow flowing inside the box 1 can flow normally and contact the filter bag 2 normally, and the filter bag 2 can filter the gas; when the gas is subjected to dust removal treatment, the gas to be treated is sent into the box 1 through the air inlet 11 and contacts the filter bag 2, and the dust and other impurities in the gas are filtered by the filter bag 2. The filtered clean gas is discharged from the outside of the box 1 through the air outlet 12, and the impurities in the gas are filtered by the filter bag 2 and fall into the ash hopper, and the impurities in the ash hopper are discharged through the discharger.

[0042] After the dust collector has been working for a period of time, when the filter bag 2 needs to be cleaned, the movable baffles 52 are started to rotate, and the movable baffles 52 on the front and rear sides of a single filter bag 2 rotate in the opposite direction. After the two sets of movable baffles 52 rotate, they move closer to each other and surround the outside of the filter bag 2. The movable baffles 52 are Figure 6 becomes Figure 8The state of the filter bag 2 is isolated by the isolation mechanism 5 to prevent the airflow in the box body 1 from contacting the filter bag 2, and the pulse valve is started to spray high-pressure air into the filter bag 2. The high-pressure air is used to perform an instantaneous pulse impact on the filter bag 2 to make the dust impurities on the surface of the filter bag 2 fall off to improve the self-cleaning degree of the filter bag 2. After cleaning, the movable enclosure 52 is started to rotate to the initial state, and the filter bag 2 can continue to perform filtering work. In this way, the function of cleaning the filter bag 2 without stopping the machine is realized; when the pulse dust collector is in use, each filter bag 2 can be cleaned alternately, which greatly reduces the impact on the airflow in the box body 1 and improves the problem that the traditional pulse dust collector needs to isolate all the filter bags 2 in a single filter chamber during cleaning, which has a greater impact on the airflow.

[0043] It should be noted that, under the premise of reducing the impact of airflow, some filter bags 2 can also be cleaned at the same time as needed. In addition, the surface conditions of each filter bag 2 inside the dust collector are not necessarily exactly the same, so not all filter bags 2 need to be cleaned. The traditional solution of dividing the pulse dust collector into multiple filter chambers for cleaning still has the problem of unnecessary increase in cleaning work. When the pulse dust collector is in use, it can also detect the pressure of each filter bag 2, so as to perform targeted cleaning on each filter bag 2 to improve this problem.

[0044] like Figure 2-6 As shown, the fixed baffle 51 is located at the center of the front and rear rows of filter bags 2, and the two movable baffles 52 in the same group are symmetrically distributed about the fixed baffle 51, and the fixed baffle 51 and the movable baffle 52 are arranged in a straight line.

[0045] Specifically, initially, the movable enclosure panels 52 and the fixed enclosure panels 51 in the same row are in a straight line to reduce the impact on the gas flow inside the box body 1 .

[0046] like Figure 2-8 As shown, the control mechanism 6 includes: a magnetic conductive plate 61 fixedly connected to the movable enclosure 52; a plurality of electromagnets 62 arranged inside the box body 1, and the electromagnets 62 are respectively located on both sides of the movable enclosure 52; and a reset torsion spring arranged on the movable enclosure 52.

[0047] Specifically, the electromagnet 62 can be arranged inside the box body 1 or on the fixed enclosure 51. Initially, the electromagnet 62 is not energized, and the movable enclosure 52 maintains a straight line with the fixed enclosure 51 under the action of the reset torsion spring; when the filter bag 2 is cleaned, the electromagnet 62 close to the side of the filter bag 2 is started and energized. After being energized, the electromagnet 62 has magnetism and is attracted to the magnetic plate 61, driving the movable enclosure 52 to rotate until it surrounds the outside of the filter bag 2; after cleaning, the electromagnet 62 is de-energized, and the movable enclosure 52 automatically rotates to the initial state.

[0048] By controlling the alternating power supply of the multiple groups of electromagnets 62 , the function of isolating the filter bags 2 alternately can be achieved, so that each filter bag 2 can be cleaned separately.

[0049] like Figure 2-8 As shown, the movable enclosure 52 includes: a rotating plate 521 rotatably connected to the fixed enclosure 51; a telescopic plate 522 slidably arranged inside the rotating plate 521; and a tension spring 523 for driving the telescopic plate 522 to retract inside the rotating plate 521.

[0050] Specifically, the return torsion spring is arranged on the rotating shaft of the rotating plate 521, and a slide groove for accommodating the telescopic plate 522 is arranged inside the rotating plate 521; when the distance between two adjacent filter bags 2 is small, in order to prevent the movable enclosing plate 52 from touching the filter bags 2 during the rotation process, the movable enclosing plate 52 is set to a telescopic structure. Figure 6 In the process, initially, the telescopic plate 522 is retracted inside the rotating plate 521, so that the rotating plate 521 can rotate close to the filter bag 2 to be cleaned, and the movable enclosure 52 does not touch the filter bag 2. After the rotating plate 521 approaches the filter bag 2 to be cleaned, the telescopic plate 522 extends outward. Figure 8 In the embodiment, after the two sets of telescopic plates 522 are extended, they surround the periphery of the filter bag 2 together with the rotating plate 521 and the fixed enclosing plate 51 .

[0051] like Figure 4-5 As shown, after the rotating plate 521 rotates, the magnetic conductive plate 61 contacts the electromagnet 62, and the control mechanism 6 further includes: a magnetic block 63 fixedly connected to the telescopic plate 522, the magnetic conductive plate 61 is aligned with the magnetic block 63, and the two ends of the magnetic conductive plate 61 extend to the two sides of the rotating plate 521 respectively.

[0052] Specifically, the two ends of the tension spring 523 are connected to the slide slot and the telescopic plate 522 respectively, and the magnetic conductive plate 61 passes through the slide slot of the rotating plate 521, and the magnetic conductive plate 61 is horizontally aligned with the magnetic block 63. Initially, the electromagnet 62 is not energized, and the telescopic plate 522 shrinks inside the rotating plate 521 under the pull of the tension spring 523; when the filter bag 2 is cleaned, the electromagnet 62 is energized, attracts the magnetic conductive plate 61 and drives the rotating plate 521 to rotate. After the rotating plate 521 rotates, the magnetic conductive plate 61 contacts the electromagnet 62 and is magnetized. After the magnetic conductive plate 61 is magnetized, the magnetic properties of the side opposite to the magnetic block 63 are the same, and the telescopic plate 522 is pushed outward under the action of the same repulsive force. The repulsive force between the magnetized magnetic conductive plate 61 and the magnetic block 63 is greater than the force of the tension spring 523 on the telescopic plate 522.

[0053] like Figure 2-3 As shown, the control mechanism 6 is arranged at the end of the isolation mechanism 5 .

[0054] Specifically, the control mechanism 6 is disposed at the top end of the isolation mechanism 5 to reduce the impact on the gas flow in the box 1. Depending on the specific situation, the control mechanism 6 can also be disposed at the bottom end of the isolation mechanism 5.

[0055] Embodiment 2

[0056] like Figure 2-7 As shown, compared with Example 1, another embodiment of the present invention is: it also includes a plurality of positioning mechanisms 7 for positioning the movable enclosure 52, and the positioning mechanism 7 includes: a rotating rod 71 rotatably arranged on the fixed enclosure 51; support rings 72 respectively fixedly connected to the two ends of the rotating rod 71; a positioning plate 73 fixedly connected to the support ring 72, and the rotating plate 521 is clamped between the two positioning plates 73.

[0057] Specifically, in the initial state, the positioning plate 73 is stuck on the front and rear sides of the rotating plate 521 to prevent the rotating plate 521 from rotating, so that the rotating plate 521 and the fixed enclosure 51 can stably maintain a straight line, thereby improving the problem that the rotating plate 521 rotates to affect the airflow inside the box 1 when dust is not cleaned.

[0058] like Figure 4-7 As shown, the positioning mechanism 7 also includes: a limiting rod 74 fixedly connected to the support ring 72; a blade 75 fixedly connected to the support ring 72, when the gas inside the box body 1 flows, the blade 75 is blown to rotate, and drives the positioning plate 73 to be stuck on the outside of the rotating plate 521; the positioning plate 73 is stuck on the outside of the rotating plate 521 under the action of the center of gravity of the positioning mechanism 7.

[0059] Specifically, the positioning mechanism 7 is an eccentric structure as a whole. Initially, the positioning mechanism 7 rests on the rotating plate 521 under the action of the center of gravity. At this time, the limiting rod 74 is against the top of the rotating plate 521, and the positioning plate 73 is stuck on the outside of the rotating plate 521. When filtering the gas, the airflow inside the box 1 contacts the blade 75 and pushes the blade 75 and the support ring 72 to rotate, further making the limiting rod 74 against the rotating plate 521, thereby ensuring that the positioning plate 73 stably sticks to the rotating plate 521 and prevents the rotating plate 521 from rotating. Through the center of gravity design of the positioning mechanism 7, coupled with the cooperation of the blade 75 and the airflow, the position stability of the rotating plate 521 during the filtration process is improved.

[0060] like Figure 4-7 As shown, the control mechanism 6 further includes a magnetic strip 64 fixedly connected to the support ring 72 , and the magnetic strip 64 is in an arc shape. When the electromagnet 62 is energized, the suction force between the magnetic strip 64 drives the positioning plate 73 to rotate.

[0061] Specifically, when the filter bag 2 is cleaned, the electromagnet 62 is started and energized. After being energized, the electromagnet 62 is attracted to the magnetic strip 64, thereby driving the support ring 72 and the positioning plate 73 to rotate, so that the positioning plate 73 rotates to separate from the rotating plate 521. After losing the restraint of the positioning plate 73, the suction force between the electromagnet 62 and the magnetic strip 61 can drive the rotating plate 521 to rotate.

[0062] by Figure 4 Taking the positioning mechanism 7 on the middle right as an example, after the electromagnet 62 is energized, the left end of the electromagnet 62 is attracted to the magnetic strip 64, driving the support ring 72 to rotate counterclockwise, so that the positioning plate 73 rotates to the top of the rotating plate 521, and the right end of the electromagnet 62 is attracted to the magnetic plate 61 on the rotating plate 521, driving the rotating plate 521 to rotate.

[0063] It should be noted that a gap may be left between the magnetic conductive strip 64 and the electromagnet 62 , or a slot for the magnetic conductive strip 64 to move may be provided in the electromagnet 62 .

[0064] like Figure 7 As shown, a slope is provided at the bottom end of the positioning plate 73, and when the rotating plate 521 rotates and resets, the positioning plate 73 is pushed to rotate by the slope.

[0065] Specifically, during dust cleaning, the rotating plate 521 rotates and covers the outside of the filter bag 2. At this time, the positioning plate 73 may be reset to its initial state. After dust cleaning is completed, the rotating plate 521 rotates and contacts the slope on the positioning plate 73, pushing the positioning plate 73 to rotate, and then the rotating plate 521 can rotate back to its initial position.

[0066] Working principle: When the gas is subjected to dust removal treatment, the gas to be treated is sent into the box 1 through the air inlet 11 and contacts with the filter bag 2. The dust and other impurities in the gas are filtered by the filter bag 2. The filtered clean gas is discharged from the outside of the box 1 through the air outlet 12. The impurities in the gas are filtered by the filter bag 2 and fall into the ash hopper. The impurities in the ash hopper are discharged through the discharger.

[0067] After the dust collector has been working for a period of time, when the filter bag 2 needs to be cleaned, the electromagnet 62 is started and energized. After the electromagnet 62 is energized, it is attracted to the magnetic strip 64, thereby driving the support ring 72 and the positioning plate 73 to rotate, so that the positioning plate 73 rotates to separate from the rotating plate 521. After the positioning plate 73 is lost, the suction force between the electromagnet 62 and the magnetic plate 61 drives the rotating plate 521 to rotate, so that the rotating plate 521 is close to the filter bag 2 to be cleaned. After the rotating plate 521 rotates, the magnetic plate 61 contacts the electromagnet 62 and is magnetized. The magnetism of one side of the opposite side of the magnetic block 63 is the same, and the telescopic plate 522 is pushed outward under the action of the same repulsive force; the movable enclosure plates 52 on the front and rear sides of the single filter bag 2 rotate in the opposite direction, and after the two sets of telescopic plates 522 are extended, they surround the surrounding side of the filter bag 2 together with the rotating plate 521 and the fixed enclosure plate 51, and isolate the filter bag 2 to prevent the airflow in the box body 1 from contacting the filter bag 2; the pulse valve is started to spray high-pressure air into the filter bag 2, and the high-pressure air is used to perform an instantaneous pulse impact on the filter bag 2, so that the dust impurities on the surface of the filter bag 2 fall off, so as to improve the self-cleaning degree of the filter bag 2;

[0068] After cleaning, the electromagnet 62 is powered off, and the telescopic plate 522 shrinks inside the rotating plate 521 under the pull of the tension spring 523. The rotating plate 521 rotates back to its initial state, and the positioning plate 73 re-locks the rotating plate 521, so that the rotating plate 521 and the fixed enclosure 51 remain stably in a straight line, and the filter bag 2 can continue to perform filtering work. In this way, the function of cleaning the filter bag 2 without stopping the machine is realized.

[0069] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
