Description

Technical Field

[0001] This utility model relates to the field of dust collectors, and more specifically, to a dust collector filtration structure. Background Technology

[0002] Dust collectors are a general term for all equipment used to remove particulate matter from gases. They can be divided into various types according to different working principles, among which baghouse dust collectors are one type of dust collector.

[0003] The main working principle of a baghouse dust collector is to capture dust through the filtration effect of the fiber fabric. When the dust-laden gas passes through the filter bag, the particles are trapped on the surface and the clean gas is discharged. Therefore, the filter bag made of fiber fabric is the main filtration structure of the baghouse dust collector. The dust-laden gas enters the dust collector inlet and reaches the bottom of the filter bag. After passing through the filter bag, the dust in the gas is trapped on the outer surface of the filter bag. The gas then flows out from the outlet after passing through the filter bag.

[0004] The existing filter bags are fixedly connected to the tube sheet inside the dust collector. The tube sheet has several round holes, and a spring ring is installed at the opening of the filter bag. The elastic tension of the spring ring tightly presses the filter bag opening against the edge of the round hole to prevent short-circuit leakage of dust-laden gas. To prevent the filter bag surface from being blocked by dust, compressed gas is periodically injected into the filter bag to backflush it, thereby washing off the dust on the filter bag surface and ensuring the filtration effect of the filter bag. However, during the backflushing process of compressed gas, the filter bag will undergo overall stretching deformation. After long-term stretching deformation, the filter bag is prone to damage or even falling off. It is quite troublesome to remove the filter bag from the dust collector after it falls off.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a dust collector filter structure.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a dust collector filtration structure, including a dust collector body, a tube sheet inside the dust collector body, a plurality of circular holes on the tube sheet, filter bags inside the circular holes, a spring ring at the opening of the filter bag, a support frame fixedly connected to the lower side of the tube sheet below the circular holes, the support frame including a base plate and a plurality of support rods, the support rods being arranged in a circular array around the center line of the circular holes, the base plate being slidably connected to the support rods, and a skeleton being provided inside the filter bag, the lower end of the skeleton pressing the bottom of the filter bag against the base plate, the skeleton being able to drive the base plate to move along the support rods.

[0008] The present invention is further configured such that: the frame includes a snap ring, a connecting rod and an abutment block, the two ends of the connecting rod are fixedly connected to the snap ring and the abutment block respectively, and the upper side of the flower plate is provided with a convex ring surrounding the circular hole, and the snap ring is snapped into the outer edge of the convex ring.

[0009] The present invention is further configured such that: a magnetic sheet is provided inside the contact block, and the magnetic sheet is used to attract the base plate.

[0010] The present invention is further configured such that: the connecting rods are arranged in a circular array with the center line of the contact block as the axis, and the distance between the connecting rods and the center of the contact block is less than the radius of the contact block.

[0011] The present invention is further configured such that: a reinforcing ring is provided on the support frame, all support rods located on the support frame are welded to the reinforcing ring, and the reinforcing ring is located near the upper end of the support frame.

[0012] The present invention is further configured such that the distance from the connecting rod to the center of the snap ring is equal to the inner diameter of the snap ring.

[0013] In summary, this utility model has the following beneficial effects:

[0014] The frame is installed inside the filter bag, and the lower end of the frame presses the bottom of the filter bag tightly against the base plate, allowing the filter bag to unfold entirely within the support frame. When compressed gas is used for backflushing, the support frame can restrict the filter bag from deforming, thereby reducing the risk of filter bag rupture. Even if the filter bag falls off, it will not fall into the dust collector body, but into the support frame. By moving the base plate upward, the filter bag that has fallen into the support frame can be removed, making it convenient for people to operate. Attached Figure Description

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] A dust collector filter structure, such as Figure 1 , Figure 2 and Figure 3 As shown, the dust collector includes a main body, inside which is a tube sheet 1. The tube sheet 1 has several circular holes arranged in a linear array. Filter bags 2 are placed inside the holes, and spring rings 3 are located at the openings of the filter bags 2. When a filter bag 2 is placed into a hole, the spring rings 3 at the openings are engaged with the inner edge of the hole, thus fixing the filter bag 2 to the tube sheet 1. A support frame located below the holes is fixedly connected to the lower side of the tube sheet 1. The support frame includes a base plate 4 and several support rods 5, arranged in a circular array around the center line of the holes. The base plate 4 is slidably connected to the support rods 5. A frame is also provided inside the filter bags 2. The bottom of the filter bag 2 is pressed against the base plate 4. The frame can move the base plate 4 along the support rod 5. After the filter bag 2 is fixed on the tube sheet 1, the frame is installed inside the filter bag 2. The lower end of the frame presses the bottom of the filter bag 2 against the base plate 4, so that the filter bag 2 unfolds inside the support frame. When compressed gas is used for backflushing, the support frame can restrict the filter bag 2 from deforming, thereby reducing the risk of the filter bag 2 breaking. Even if the filter bag 2 falls off, it will not fall into the dust collector body, but into the support frame. By moving the base plate 4 upward, the filter bag 2 that has fallen into the support frame can be taken out, which is convenient for operation.

[0022] like Figure 2 , Figure 3 and Figure 4 As shown, the frame includes a snap-fit ​​ring 6, a connecting rod 7, and an abutment block 8. The two ends of the connecting rod 7 are fixedly connected to the snap-fit ​​ring 6 and the abutment block 8, respectively. A protruding ring 9 surrounding a circular hole is provided on the upper side of the tube sheet 1. The snap-fit ​​ring 6 snaps onto the outer edge of the protruding ring 9. The snap-fit ​​ring 6 is connected to the abutment block 8 via the connecting rod 7, allowing the movement of the snap-fit ​​ring 6 to drive the movement of the abutment block 8. The snap-fit ​​ring 6 is thus fitted and snapped onto the protruding ring 9, causing the abutment block 8 to press the filter bag 2 firmly onto the base plate 4. A magnetic attraction is provided inside the abutment block 8. The magnetic plate 10 is used to attract the base plate 4, which is made of iron. The magnetic plate 10 attracts the lower end of the frame to move the base plate 4 upward. The connecting rods 7 are arranged in a circular array around the center line of the contact block 8. The distance between the connecting rods 7 and the center of the contact block 8 is less than the radius of the contact block 8. When the frame is put into the filter bag 2, there is a distance between the connecting rods 7 and the inner wall of the filter bag 2, so that the inner wall of the filter bag 2 will not be pressed tightly, thus ensuring the filtration area of ​​the filter bag 2.

[0023] like Figure 3 and Figure 4As shown, a reinforcing ring 11 is provided on the support frame. All the support rods 5 in the support frame are welded to the reinforcing ring 11. The reinforcing ring 11 is located near the upper end of the support frame. The setting of the reinforcing ring 11 increases the connection between each support rod 5, thereby ensuring the overall strength of the support frame. Furthermore, the reinforcing ring 11 is located at the upper end of the support frame, so that there is enough distance below the reinforcing ring 11 for the base plate 4 to slide. The distance from the connecting rod 7 to the center of the snap ring 6 is equal to the inner diameter of the snap ring 6. This can maximize the cavity in the center of the snap ring 6, which facilitates the filling of compressed gas.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
