Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, in particular to a dust removal device for a dust collector. Background Art

[0002] As society's environmental protection requirements become increasingly stringent, dust removal equipment is also constantly developing. The dust removal device is an important component of the dust collector, used to remove dust from the dust collector. The conventional dust removal device includes a cone-shaped dust hopper. When in use, the dust is discharged from the dust removal port of the dust hopper by relying on its own fluidity.

[0003] The existing ash hopper often encounters the following problems when discharging ash: as the ash is discharged, the ash temperature in the ash hopper drops and the fluidity of the ash decreases, resulting in difficulty in discharging the ash, a long ash discharging time, or even no ash discharging at all; in addition, the height of the ash in the ash hopper varies. For areas with higher ash accumulation, the ash near the ash discharge port is subjected to greater pressure, causing this part of the ash to become compacted and unable to be discharged.

[0004] In order to solve the problem of difficulty in discharging dust from the ash hopper, some ash unloading devices are equipped with stirring blades on the side wall of the ash hopper. When working, the stirring blades stir the dust in the ash hopper to enhance the fluidity of the dust. However, this method has a small stirring range and there are dead corners for dust accumulation, which cannot fundamentally solve the problem of difficulty in discharging dust.

[0043] Reference Figure 1 The utility model provides a dust removal device for a dust collector, which comprises a dust hopper 1, a sweeper 2 and a driving mechanism 3;

[0044] An ash discharge port 121 is provided at the bottom of the ash hopper 1, and a sweeper 2 is rotatably arranged at the bottom of the ash hopper 1, and the rotation axis of the sweeper 2 coincides with the center of the ash discharge port 121; a driving mechanism 3 is used to drive the sweeper 2 to rotate;

[0045] The sweeper 2 extends from the ash discharge port 121 toward the side wall of the ash hopper 1 .

[0046] During operation of the above-mentioned device, the driving mechanism 3 drives the sweeper 2 to rotate in the ash hopper 1 around the center of the ash discharge port 121; since the sweeper 2 extends from the ash discharge port 121 to the side wall of the ash hopper 1, the sweeper 2 will clean and stir the dust at the bottom of the ash hopper 1 during the rotation, thereby improving the overall fluidity of the ash in the ash hopper, preventing the ash at the bottom of the ash hopper 1 from becoming compacted, and accelerating the discharge of dust; in addition, the sweeper 2 will gradually gather the dust on the periphery of the bottom of the ash hopper 1 to the ash discharge port 121 during the rotation, preventing the accumulation of dust on the periphery of the bottom of the ash hopper 1, thereby further accelerating the discharge of dust.

[0047] Reference Figure 2 and Figure 3 The driving mechanism 3 includes a driving source 31 and a transmission assembly, wherein: the driving source 31 is arranged on the outer wall of the ash hopper 1; one end of the transmission assembly is connected to the output end of the driving source 31, and the other end of the transmission assembly extends into the interior of the ash hopper 1 and is connected to the sweeper 2.

[0048] In this embodiment, the transmission assembly includes a worm gear reducer 32, a first transmission shaft 33 and a second transmission shaft 34, wherein: one end of the first transmission shaft 33 is connected to the output end of the driving source 31, and the other end of the first transmission shaft 33 extends into the interior of the ash hopper 1; the worm gear reducer 32 is connected between the first transmission shaft 33 and the second transmission shaft 34; and the end of the second transmission shaft 34 away from the worm gear reducer 32 is connected to the sweeper 2.

[0049] In the above structure, the driving source 31 is arranged on the outside of the dust hopper 1, which avoids dust from directly contacting the driving source 31 and can improve the service life of the driving source 31; in addition to the conventional deceleration and torque transmission functions, the worm gear reducer 32 can also change the transmission direction, so that the first transmission shaft 33 and the second transmission shaft 34 are perpendicular, and the torque of the driving source 31 is transmitted to the sweeper 2.

[0050] Based on the above structure, refer to Figure 3 A crossbeam is connected between the two opposite side walls of the ash hopper 1, and a worm gear reducer 32 is installed on the crossbeam; a first transmission shaft 33 is parallel to the crossbeam, and its two ends are respectively connected to the driving source 31 and the worm gear reducer 32; a second transmission shaft 34 is perpendicular to the crossbeam and is coaxially arranged with the ash discharge port 121, and its two ends are respectively connected to one end of the sweeper 2 and the worm gear reducer 32; the other end of the sweeper 2 extends toward the side wall of the ash hopper 1.

[0051] In this embodiment, the driving source 31 is a variable frequency motor, which is fixed to the outer wall of the dust hopper 1 through a mounting plate and fasteners. The variable frequency motor can adjust the speed according to the amount of dust, thereby speeding up or slowing down the cleaning speed, making the device more controllable and convenient for users to operate.

[0052] Reference Figure 4 The sweeper 2 includes a fixed portion 21 and a rotating rod 22 which are connected to each other, wherein: the fixed portion 21 is connected to the driving mechanism 3; the rotating rod 22 extends from the fixed portion 21 to the side wall of the ash hopper 1.

[0053] Specifically, the fixing part 21 is a cylindrical structure, which is sleeved on the second transmission shaft 34; a plurality of fasteners (such as bolts) are provided through the side wall of the fixing part 21, and the fixing part 21 is fixed to the second transmission shaft 34 by the fasteners. One end of the rotating rod 22 is fixed to the fixing part 21 by welding or screwing, and the other end thereof extends toward the side wall of the ash hopper 1. When the above device is working, the second transmission shaft 34 rotates, driving the fixing part 21 and the rotating rod 22 to rotate synchronously.

[0054] Figure 4 In the illustrated embodiment, the rotating rod 22 extends linearly from the fixing portion 21 toward the side wall of the ash hopper 1. Figure 5 , Figure 5 In the illustrated embodiment, the rotating rod 22 extends in an arc shape from the fixed portion 21 to the side wall of the ash hopper 1. Compared with the rotating rod 22 having a linear structure, the rotating rod 22 having an arc structure has a better dust collection effect and is more conducive to the dust moving toward the ash discharge port 121.

[0055] Continue to refer to Figure 4 and Figure 5 The cleaner 2 further includes a plurality of cleaning plates 23, which are sequentially connected to the lower part of the rotating rod 22 along the extension direction of the rotating rod 22. The cleaning plates 23 can be fixed to the rotating rod 22 by welding or detachable connection, and the cleaning plates 23 can rotate synchronously with the rotating rod 22 to clean the dust at the bottom of the ash hopper 1 and collect it to the ash discharge port 121.

[0056] In this embodiment, each cleaning plate 23 is set at an angle to the rotating rod 22. The angle between the two is set according to actual usage requirements and is not limited here.

[0057] On the basis of the above structure, the cleaning plate 23 is rotatably connected to the rotating rod 22, and a locking structure for fixing the cleaning plate 23 is also provided on the rotating rod 22. In normal use, the cleaning plate 23 is fixed to the rotating rod 22 by the locking structure; when the angle between the cleaning plate 23 and the rotating rod 22 needs to be adjusted, the locking structure is loosened so that the cleaning plate 23 can rotate relative to the rotating rod 22, and the angle between the two is adjusted to a suitable size; then, the cleaning plate 23 is fixed to the rotating rod 22 again by the locking structure. Through the above process, the angle between the cleaning plate 23 and the rotating rod 22 can be adjusted to a suitable size, thereby improving the cleaning and collection effect of the cleaner 2 on dust.

[0058] Reference Figure 6 , the number of the sweepers 2 is one or more; when the number of the sweepers 2 is more than one, the multiple sweepers 2 are sequentially arranged around the center of the ash discharge port 121. Optionally, the multiple sweepers 2 may share the same fixing portion 21. The multiple sweepers 2 can improve the cleaning efficiency of the accumulated ash and further accelerate the discharge of the dust.

[0059] Reference Figure 7 and Figure 8 The ash hopper 1 includes a barrel 11 and a bottom plate 12 arranged at the bottom of the barrel 11, and an ash discharge port 121 is opened on the bottom plate 12; the distance between the sweeper 2 and the bottom plate 12 is in the range of 2 to 3 mm.

[0060] In the above structure, the sweeper 2 is spaced apart from the bottom plate 12 to avoid the problem of the sweeper 2 scratching the bottom plate 12 and causing the sweeper 2 to get stuck; the distance between the sweeper 2 and the bottom plate 12 is in the range of 2 to 3 mm. For example, the distance between the two can be 2 mm or 2.5 mm or 3 mm. This distance can prevent the dust on the bottom plate 12 from being compacted, thereby achieving the purpose of effective dust removal.

[0061] Further, the barrel 11 is funnel-shaped; optionally, the barrel 11 is cone-shaped or pyramid-shaped as a whole. In this embodiment, the barrel 11 is pyramid-shaped as a whole, and the outer contour of the cross section of the barrel 11 is rectangular.

[0062] Reference Figure 7 and Figure 8 The bottom plate 12 is funnel-shaped or flat-plate-shaped, and the outer contour of the cross section of the bottom plate 12 is circular. Figure 7 In the illustrated embodiment, the bottom plate 12 is in the shape of a conical funnel; Figure 8 In the illustrated embodiment, the bottom plate 12 is in the shape of a circular flat plate. Of the two types of bottom plates 12, the funnel-shaped bottom plate 12 is more conducive to improving the fluidity of dust at the bottom of the dust hopper 1, and facilitates the dust to flow toward the center.

[0063] In the above structure, the taper of the bottom plate 12 is smaller than that of the barrel 11, the top of the ash hopper 1 is a tetrahedral pyramid with a larger slope, and the bottom is a cone with a smaller slope, and the upper and lower transitions form an irregular conical ash hopper. Compared with the conical ash hopper with a smooth transition as a whole in the prior art, the side wall of the ash hopper 1 in this embodiment is steeper and the side walls are smoothly transitioned so that dust is not easily accumulated, which further increases the fluidity of dust and facilitates the dust to flow to the bottom plate 12; the outer contour of the cross section of the bottom plate 12 is circular, so that the cleaning range of the sweeper 2 can cover the entire bottom plate 12, completely eliminating the dead corners of dust accumulation.

[0064] For conventional ash hoppers with a smooth transition as a whole, if the taper is too small, the dust will have poor fluidity and poor dust discharge effect; if the taper is too large, the height of the dust collector will be greatly increased, which will increase the space it occupies and fail to meet the use requirements of places with limited space. Compared with the existing ash hoppers, the height of the ash hopper 1 in this embodiment is greatly reduced due to the provision of the bottom plate 12, thereby reducing the overall height of the dust collector and meeting the use requirements of more space; during operation, the dust on the bottom plate 12 is cleaned and gathered toward the center by the sweeper 2 to prevent dust accumulation on the bottom plate 12 and accelerate the discharge of dust.

[0065] Continue to refer to Figure 7 and Figure 8 The cleaning plate 23 includes a horizontal portion and a vertical portion connected in an L-shape, wherein: the horizontal portion is welded or detachably connected to the lower end surface of the rotating rod 22; the upper end of the vertical portion is connected to the horizontal portion, and the distance between the lower end surface of the vertical portion and the bottom plate 12 is in the range of 2 to 3 mm. Figure 7 In the embodiment where the barrel 11 is funnel-shaped, the height of the vertical portions of the plurality of cleaning plates 23 decreases from the ash discharge port 121 to the side wall of the ash hopper 1 .

[0066] During operation of the above-mentioned device, the driving mechanism 3 drives the sweeper 2 to rotate around the center of the ash discharge port 121, and the rotating rod 22 drives the cleaning plate 23 to rotate synchronously; the multiple cleaning plates 23 can gradually clean the dust accumulated on the periphery of the bottom plate 12 and collect it to the ash discharge port 121, thereby improving the overall fluidity of the dust inside the ash hopper 1 and accelerating the discharge of the accumulated dust; the configuration of the bottom plate 12 ensures that the sweeper 2 has no dead corners to clean during operation, completely solving the problem of difficulty in discharging dust from the ash hopper 1.

[0067] The device provided by the utility model has a flexible and reliable operation mode, is easy for personnel to operate and maintain, and has a high degree of equipment operation safety; in addition, the device has a simple structure, few parts, a low damage rate, a small amount of maintenance, and a low after-sales cost.

[0068] In the device provided in the present application, a vibrator can also be arranged on the side wall of the ash hopper 1 to further enhance the fluidity of the dust; and / or, a screw conveyor or a star-shaped discharger or other structure can be arranged at the bottom of the ash hopper 1 to prevent the ash discharge port 121 from being blocked, thereby further accelerating the discharge of dust.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
