Description

Technical Field

[0001] The utility model relates to the technical field of dust removal bags, in particular to a foldable bag. Background Art

[0002] Bag dust collector, also known as filter dust collector, is a dry high-efficiency dust collector. It is a dust removal device that uses bag filter elements made of fiber woven fabric to capture solid particles in dust-containing gases. Its working principle is that dust particles are intercepted by colliding with the fibers due to inertia when they pass around the filter cloth fibers. The dust bag is a key part in the operation of the bag dust collector. Usually, the cylindrical filter bag is hung vertically in the dust collector.

[0003] For example, a foldable glass fiber dust bag with the publication (announcement) number CN210448430U belongs to the technical field of dust bag, and includes a fixed cylinder and a first fixed seat, the outer side of the fixed cylinder is provided with a protrusion, the outer side of the dust bag is provided with an extrusion mechanism, the inner sides of the first extrusion plate and the second extrusion plate are provided with grooves, a glass fiber bag is provided on the side of the wear-resistant layer away from the metal wire mesh layer, a first fixing rib is installed on the upper end of the first fixed seat, and a second fixing rib is installed on the upper end of the second fixed seat. The bag is inserted into the groove by the protrusion, so as to squeeze and fold the dust bag to increase the working efficiency and filtering area of ​​the bag, but because the bag is still a single-layer structure after folding, when the gas is dust-filtered, the filtering effect on the gas is limited, and it cannot adapt to the filtering requirements of different gases, which is inconvenient.

[0004] Therefore, a foldable cloth bag has been developed that can fold the filter cloth to form a double-layer structure to adapt to different gas filtration requirements. Utility Model Content

[0005] In order to overcome the shortcomings of the existing cloth bag with a single-layer structure, which has limited filtering effect on the gas when performing dust removal and filtering on the gas and cannot adapt to the filtering requirements of different gases, the utility model provides a foldable cloth bag which can fold the filter cloth to form a double-layer structure to adapt to different gas filtering requirements.

[0006] The technical solution is: a foldable cloth bag, comprising a first connecting plate, a second connecting plate and a first fixing screw, wherein the left part of the first connecting plate is connected to the second connecting plate through a plurality of first fixing screws.

[0007] Furthermore, it also includes connecting rods, rotating rods and fixed rods. The lower sides of the first connecting plate and the second connecting plate are connected to multiple connecting rods, the lower sides of the connecting rods are rotatably connected to the rotating rods, and the lower sides of the rotating rods are rotatably connected to the fixed rods.

[0008] Furthermore, a second fixing screw is included, and the lower part of the fixing rod is clamped with the second fixing screw.

[0009] Furthermore, it also includes a cover plate and third fixing screws. The cover plate is arranged between the lower parts of the fixing rods. The upper part of the cover plate is threadedly connected with a plurality of third fixing screws. The third fixing screws are all in contact with adjacent fixing rods.

[0010] Furthermore, each of the third fixing screws has a slot.

[0011] Furthermore, it also includes a filter cloth, and the filter cloth is connected between the connecting rod, the rotating rod and the fixed rod.

[0012] Beneficial effect: The utility model rotates the connecting rod and the fixed rod to a relatively horizontal state through the rotating rod, so that the rotating rod contacts the cover plate, folds the filter cloth, and then connects the second fixing screw to the first connecting plate and the second connecting plate to fix the fixed rod, thereby achieving the effect of being able to fold the filter cloth to form a double-layer structure to adapt to different gas filtration requirements.

[0019] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention.

[0020] A foldable cloth bag, such as Figure 1-Figure 5As shown, it includes a first connecting plate 1, a second connecting plate 2, a first fixing screw 3, a connecting rod 4, a rotating rod 5, a fixed rod 6, a second fixing screw 7, a covering plate 8, a third fixing screw 9 and a filter cloth 10. The left part of the first connecting plate 1 is connected to the second connecting plate 2 by two first fixing screws 3. Fourteen connecting rods 4 are connected to the lower sides of the first connecting plate 1 and the second connecting plate 2. The lower sides of the connecting rods 4 are rotatably connected to the rotating rods 5. The lower sides of the rotating rods 5 are rotatably connected to the fixed rods 6. The lower parts of the fixed rods 6 are clamped with the second fixing screws 7. A covering plate 8 is provided between the lower parts of the fixed rods 6. Three third fixing screws 9 are threadedly connected to the upper parts of the covering plate 8. The third fixing screws 9 are all provided with slots for easy rotation and tightening. The third fixing screws 9 are in contact with adjacent fixed rods 6. Filter cloth 10 is connected between the connecting rods 4, the rotating rods 5 and the fixed rods 6.

[0021] When using the utility model, first connect the first connecting plate 1 and the second connecting plate 2 by the first fixing screw 3, and then connect the cover plate 8 between the fixing rods 6 by the third fixing screw 9, and then install the first connecting plate 1 and the second connecting plate 2 in the filter dust collector. After the gas passes into the filter dust collector, the filter cloth 10 intercepts the dust particles in the gas, and the gas can only be discharged from the filter cloth 10 through the cover plate 8, so as to ensure the dust removal effect of the gas. When there are many dust particles in the gas, the connecting rod 4 and the fixing rod 6 can be rotated to a relatively horizontal state by the rotating rod 5, so that the rotating rod 5 contacts the cover plate 8, and the filter cloth 10 is folded, and then the second fixing screw 7 is connected to the first connecting plate 1 and the second connecting plate 2, and the fixing rod 6 is fixed, so that the filter cloth 10 can be folded into a double-layer structure to adapt to different gas filtering requirements.

[0022] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
