Problems solved by technology

People in the industry usually use glue to seal, but the operation is difficult
Similarly, the adhesive layer is easy to fall off, which cannot fundamentally solve the problem of dust discharge channels in the gaps of the cloth, and the cost is relatively high
[0009] 3. The existing technology for making the bottom of the dust filter bag is difficult to realize the mechanized production line operation
Due to the complex structure of the bag bottom of the dust filter bag, this method cannot be applied to the bottom of the bag, so the microporous belt only covers the needle seams of the bag body and the bag mouth, and cannot solve the problem of dust removal from the needle holes and cloth seams at the bottom of the bag

Embodiment 1

[0074] Such as image 3 , 4 As shown, the port 2 at the bottom end of the cylindrical bag body 1 is tightly gathered into a pinch 2' in the middle by external force, and then a C-shaped buckle 8 made of metal is used to cover the gathered filter material. The C-shaped buckle 8 used in this embodiment is spiral-shaped when viewed from the side. Then use a strong external force to make the inner diameter of the C-shaped buckle 8 shrink inwardly to produce larger plastic deformation, and its two ends are staggered and overlapped, and the bottom port 2' of the bag body after being gathered into a pinch is tightly locked. After the buckle 3 after plastic deformation loses the external force and recovers part of the deformation, it forms a stable shape that can resist a certain external force, and can still maintain the state of tightly squeezing the gathered filter materials together to ensure that the dust does not pass through channel. In addition, the tightness should also e...

Embodiment 2

[0076] Such as Figure 10 As shown, when the cutting edge 22 of the shearing device cuts out the port of the bag body that is used as the bottom of the bag, the walking mechanism (also called a trolley) of the equipment described in this patent moves synchronously in the forward direction according to the moving speed of the filter material of the production line, and the right poly Pinching template 23 and left gather pinching template 24 at distance bag body port 2-5cm place, relative movement advances to the middle part, until tubular bag body filter material is tightly squeezed into a pinch. The degree of tightness is based on the impermeability of dust and the fact that the filter bag will not fall off under working conditions. It can be realized by presetting the maximum propulsion force of the transmission mechanism. The transmission mechanism can be various transmission forms such as air cylinders, hydraulic cylinders, and electric motors.

[0077] The spring 9 in th...

Embodiment 3

[0079] Such as Figure 9 As shown, different from Embodiment 2, there is no upper press-lock push head 13 in this embodiment, and the left and right press-lock push heads are composed of two sets of press-lock action cylinders 11 and a press-lock roller 12 respectively. Each set of press-lock action cylinders can realize all-round continuous extrusion of the buckle 8 through the hinge connection and movement of the push rod, and finally complete the locking.

Abstract

A method for making the bottom of a dust-removing filter bag. The filter material at the port at the end of the cylindrical bag body (1) to be made into the bag bottom, including the cylindrical filter material connected and extended to the filter material of the bag body, is tightly Gather into a pinch to form an airtight bag bottom. At the same time, it provides the corresponding special equipment for making the bottom of the bag, as well as the corresponding buckle and seal the bottom of the bag.

Description

technical field [0001] The invention relates to a method for making the bottom of a dust removal filter bag and a filter bag produced by the method, belonging to the field of environmental protection and dust removal. The special equipment for making the bag bottom of the invention belongs to the field of special machinery for making dust removal equipment. Background technique [0002] Baghouse dust collection is an older dust collection technology. As early as the 1880s, foreign countries have begun to use it, and it has a history of more than 200 years. In the mid-1980s, under the influence of a series of environmental incidents in developed countries, my country began to pay attention to its own environmental protection, and the bag dust removal industry began to sprout in our country. With the continuous advancement of technology, the efficiency of bag dust removal has gradually increased, and it can adapt to most dust removal conditions. The processing air volume is ...
