Technical Field
[0001] The utility model relates to the technical field of removal and treatment of combustion products or combustion residues, in particular to a flow guide device at an inlet of a dust collector ash hopper. Background Art
[0002] There is a large amount of dust in the flue gas, which will pollute the environment if discharged directly into the atmosphere. Therefore, dust reduction is required before discharging it into the atmosphere. When performing dust reduction, there is a method of allowing the flue gas to fall into the filter bag through the dust collector ash hopper for dust reduction.
[0003] However, this method of directly letting the flue gas fall into the filter bag through the dust collector hopper for dust reduction has the following problems:
[0004] 1. The flue gas in the ash hopper is relatively chaotic and prone to eddy current disturbance, which can easily cause scouring and damage the upper filter bags.
[0005] 2. Directly discharging the flue gas into the filter bag will put a heavy burden on the filter bag, thereby reducing the service life of the filter bag. Utility Model Content
[0006] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a guide device for the inlet of the ash hopper of a dust collector, which can solve the problem that the smoke in the inner cavity of the ash hopper is relatively chaotic and prone to eddy disturbances and the smoke is directly discharged into the filter bag, which puts a heavy burden on the filter bag.
[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a flow guide device for the inlet of a dust collector hopper, comprising a dust collector hopper;
[0008] A shielding component capable of reducing the load on the filter bag is arranged in the dust removal hopper, and the shielding component includes guide plates, and all four guide plates are L-shaped;
[0009] A limit assembly for preventing the guide plate from falling off is arranged in the dust hopper. The limit assembly includes a top plate, a spring, a sliding groove, a second slot, a first slot, and a third slot. Multiple third slots are all arranged on the dust hopper, and multiple first slots are all arranged on the dust hopper.
[0010] Preferably, the plurality of second card slots are all arranged inside the dust removal hopper, and the plurality of second card slots are all connected to the corresponding first card slots.
[0011] Preferably, the sliding groove is arranged on the guide plate, the three springs are welded on the top plate, and the other ends of the three springs are welded inside the sliding groove.
[0012] Preferably, three third magnets are adhered to both sides of the guide plate.
[0013] Preferably, the surface of the dust removal hopper is provided with four first grooves, the insides of the four first grooves are provided with first connecting pieces, the insides of the four first connecting pieces are adhered with multiple first magnets, and the multiple first magnets pass through both sides of the corresponding first connecting pieces.
[0014] Preferably, the surface of the dust hopper is provided with four second grooves, the interiors of the four second grooves are rotatably connected with second connecting pieces, the surfaces of the four second connecting pieces are adhered with a plurality of second magnets, and the plurality of second magnets pass through both sides of the corresponding second connecting pieces.
[0015] Preferably, an air inlet pipe is welded on the surface of the dust removal hopper.
[0016] Compared with the prior art, the beneficial effects of the utility model are:
[0017] (1) The guide device at the inlet of the dust collector hopper is provided with four guide plates in the shielding assembly, and the four guide plates are arranged at appropriate positions inside the dust collector hopper. The four guide plates are arranged at appropriate positions inside the dust collector hopper, which can make the smoke entering the inner cavity of the dust collector hopper more balanced, reduce the scouring of the wall plate of the dust collector hopper, and the scouring of the upper filter bag, and avoid the eddy current disturbance in the dust collector hopper chamber to affect the upper filter bag. At the same time, the four guide plates are arranged at appropriate positions inside the dust collector hopper, which can slow down the flow rate of the smoke. The large particles of dust contained in the smoke hit the guide plates and settle into the lower hopper, and at the same time reduce the load of the filter bag, thereby extending the service life of the filter bag.
[0018] (2) The guide device at the dust collector hopper inlet increases the strength of the guide plates in the dust collector hopper by setting four guide plates in an L shape, thereby improving the service life of the four guide plates.
[0019] (3) The guide plate of the dust collector at the ash hopper inlet is prone to dust accumulation on its surface due to the long-term collision between the guide plate and the flue gas. To prevent the dust from accumulating on the surface of the guide plate for a long time, which would affect the effect of the guide plate on the flue gas and thus endanger the upper filter bags, a plurality of first magnets and third magnets are arranged to attract each other and drive the corresponding guide plates to move upward to disassemble and clean the guide plates. The guide plates are regularly disassembled and cleaned to avoid the problem of dust accumulation on the guide plates affecting the effect of the guide plates, thereby ensuring that the guide plates can accurately protect the upper filter bags.
[0020] (4) In the guide device at the inlet of the ash hopper of the dust collector, the flue gas flows on the guide plate for a long time, which may cause the guide plate to shake. The shaking of the guide plate will affect the effect of the guide plate setting. The guide plate is set in an L-shaped groove through the second slot in the limit assembly to limit the movement of the guide plate. Compared with only limiting the position of the guide plate inside the third slot, adding a restriction can improve the stability of the guide plate and reduce the probability of the guide plate moving.

[0035] See also Figure 1-8 , the utility model provides a technical solution: a flow guide device at the inlet of a dust collector ash hopper, comprising a dust collector ash hopper 2;
[0036] A shielding component capable of reducing the load on the filter bag is arranged in the dust removal hopper 2, and the shielding component includes a guide plate 8, and the four guide plates 8 are all L-shaped;
[0037] A limit assembly for preventing the guide plate 8 from falling off is arranged in the dust hopper 2, and the limit assembly includes a top plate 6, a spring 7, a sliding groove 16, a second card slot 5, a first card slot 1, and a third card slot 9. Multiple third card slots 9 are all arranged on the dust hopper 2, and multiple first card slots 1 are all arranged on the dust hopper 2.
[0038] The plurality of second slots 5 are all disposed inside the dust removal hopper 2 , and the plurality of second slots 5 are all connected to the corresponding first slots 1 .
[0039] The sliding groove 16 is arranged on the guide plate 8 , the three springs 7 are all welded on the top plate 6 , and the other ends of the three springs 7 are all welded inside the sliding groove 16 .
[0040] Three third magnets 15 are bonded to both sides of the guide plate 8 .
[0041] The surface of the dust hopper 2 is provided with four first grooves 4 , each of which is provided with a first connecting piece 10 . Each of the four first connecting pieces 10 is adhered with a plurality of first magnets 11 , which pass through both sides of the corresponding first connecting piece 10 .
[0042] Four second grooves 14 are formed on the surface of the dust hopper 2 , and the second connecting members 12 are rotatably connected inside the four second grooves 14 . A plurality of second magnets 13 are adhered to the surfaces of the four second connecting members 12 , and the plurality of second magnets 13 pass through both sides of the corresponding second connecting members 12 .
[0043] An air inlet pipe 3 is welded to the surface of the dust removal hopper 2 .
[0044] When it is necessary to install the four guide plates 8 to the appropriate position, first, place the four top plates 6 inside the corresponding first slots 1, and place the four guide plates 8 inside the corresponding third slots 9. At this time, the multiple first magnets 11 are attracted to the corresponding third magnets 15, and then drive the multiple first connecting members 10 to move downward. The downward movement of the multiple first connecting members 10 drives the corresponding guide plates 8 to move downward. During the downward movement of the four guide plates 8, the four top plates 6 gradually enter the interior of the guide plates 8. Finally, the four guide plates 8 move to the corresponding positions corresponding to the second slots 5. Then, the four first connecting members 10 are rotated so that the multiple first magnets 11 and the corresponding third magnets 15 repel each other. At the same time, the multiple second magnets 13 attract the corresponding third magnets 15 to move. Under the action of the multiple first magnets 11 and the multiple second magnets 13, the guide plate 8 enters the interior of the corresponding second slot 5 for limiting.
[0045] It should be noted that the guide plate 8 is also inside the corresponding third slot 9 when it enters the second slot 5 .
[0046] When it is necessary to disassemble and clean the four guide plates 8, first, rotate the four second connecting members 12 and the four first connecting members 10 so that the first magnet 11 attracts the third magnet 15, and the second magnet 13 repels the third magnet 15. The third magnet 15 moves to drive the guide plate 8 to move out of the corresponding second slot 5, and then drives the four first connecting members 10 to move upward to a suitable position, and then disassemble the four guide plates 8 and the four top plates 6 for cleaning.
[0047] By setting four guide plates 8 in the shielding assembly and setting the four guide plates 8 at appropriate positions inside the dust hopper 2, the four guide plates 8 at appropriate positions inside the dust hopper 2 can make the flue gas entering the inner cavity of the dust hopper 2 more balanced, reduce the scouring of the wall panels of the dust hopper 2 and the upper filter bag, and avoid the eddy current disturbance in the chamber of the dust hopper 2 to affect the upper filter bag. At the same time, the four guide plates 8 at appropriate positions inside the dust hopper 2 can slow down the flow rate of the flue gas, and the large particles of dust contained in the flue gas will settle into the lower hopper after hitting the guide plates, thereby reducing the load of the filter bag and extending the service life of the filter bag.
[0048] By arranging the four guide plates 8 to be L-shaped, the strength of the guide plates in the dust removal hopper 2 is increased, and the service life of the four guide plates 8 is improved.
[0049] Since the guide plate 8 collides with the flue gas for a long time, dust is easily accumulated on its surface. To avoid the dust accumulating on the surface of the guide plate 8 for a long time, which would affect the effect of the guide plate 8 on the flue gas and thus endanger the upper filter bag, a plurality of first magnets 11 and third magnets 15 are arranged to attract each other and drive the corresponding guide plate 8 to move upward to disassemble and clean the guide plate 8. Regularly disassembling and cleaning the guide plate 8 can avoid the problem of dust accumulating on the guide plate 8 and affecting the effect of the guide plate 8, thereby ensuring that the guide plate 8 accurately protects the upper filter bag.
[0050] When smoke flows on the guide plate 8 for a long time, the guide plate 8 may be caused to shake. The shaking of the guide plate 8 will affect the setting effect of the guide plate 8. The guide plate 8 is set in an L-shaped groove through the second slot 5 in the limiting assembly to limit the movement of the guide plate 8. Compared with only limiting the position of the guide plate 8 inside the third slot 9, adding a restriction can improve the stability of the guide plate 8 and reduce the probability of the guide plate 8 moving.
[0051] Working principle:
[0052] When it is necessary to install the four guide plates 8 to the appropriate position, first, place the four top plates 6 inside the corresponding first slots 1, and place the four guide plates 8 inside the corresponding third slots 9. At this time, the multiple first magnets 11 are attracted to the corresponding third magnets 15, and then drive the multiple first connecting members 10 to move downward. The multiple first connecting members 10 drive the corresponding guide plates 8 to move downward. During the downward movement of the four guide plates 8, the four top plates 6 gradually enter the interior of the guide plates 8. Finally, the four guide plates 8 move to the corresponding positions corresponding to the second slots 5. Then, the four first connecting members 10 are rotated so that the multiple first magnets 11 and the corresponding third magnets 15 repel each other, and the multiple second magnets 13 attract the corresponding third magnets 15 to move. Under the action of the multiple first magnets 11 and the multiple second magnets 13, the guide plates 8 enter the interior of the corresponding second slots 5.
[0053] When the four guide plates 8 need to be disassembled and cleaned, the four second connecting members 12 and the four first connecting members 10 are rotated so that the first magnet 11 attracts the third magnet 15, and the second magnet 13 repels the third magnet 15. The third magnet 15 moves to drive the guide plate 8 to move out of the corresponding second slot 5, and then drives the four first connecting members 10 to move upward.
[0054] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
