Abstract
The invention relates to a device for assisting a filter material to be folded into a filter element and a folding method. The device is used for assisting the filter material made of soft materials to be folded into a filter element, comprises a conical central fixing column and is used for fixing an inner tube of the folded filter element; a plurality of support rods are uniformly arranged on the outer ring by taking the central fixed column as a center, and the diameter of a ring formed by the support rods is matched with the inner diameter of the shell of the folding filter element; one end of the metal sheet is fixed on a support rod and forms a ring around the inner side of the support rod, and the other end of the metal sheet is either fixed or freely extended. The folded filter material is stuffed layer by layer from the opening of the ring, when the number of the inlet layers meets the requirement, the end sealing can be carried out at the opening of the ring, and then the filter material is compressed; and then sleeving one end of the annular filter material on the shell, forcibly filling the annular filter material into the shell from the other end, and finally welding an end cover of the shell to form the complete folded filter element.
Description
Technical Field
The invention relates to a device and a method for assisting filter materials to be folded into filter elements, and belongs to the field of processing of folded filter elements.
Background
The filter material stiffness in ordinary folding filter core is higher, and pleating back non-deformable can easily must fill in the skeleton and form the filter core. However, some very soft thin filter materials still deform easily after being pleated, and in order to achieve the purpose of a higher filtering area, the more the pleats of the filter materials in the framework are required to be, the better the more the pleats are, so that when the pleated filter materials are plugged into the framework, a plurality of problems occur, such as bending of the filter materials plugged into the framework or uneven phenomenon occur, or the more the pleats are, cliff breaking phenomenon occurs, and the filter materials cannot be plugged into the framework.
Disclosure of Invention
The invention relates to a device for assisting a filter material to be folded into a filter element and a folding method. The device is used for assisting the filter material of soft material to fold into the filter core, solves the various problems that appear when the filter material after pleating is filled in the skeleton, also can fill in the skeleton with the higher filter material of pleat number simultaneously, forms high filter area's folding filter core.
The invention discloses a device for folding auxiliary filter materials into filter elements, which comprises the following parts:
a device for assisting filter materials to be folded into filter elements comprises a conical central fixing column and an inner tube, wherein the inner tube is used for fixing the folded filter elements; one end of the metal sheet is fixed on one support rod, a ring is formed around the inner sides of the support rods, and the other end of the metal sheet is either fixed or freely extended.
Preferably, the metal sheet has a width in the range of nine tenths to one half of the width of the filter material.
Preferably, the number of the supporting rods is more than four.
Preferably, two or more circles of support rods are arranged according to the different diameters of the processed folding filter element.
The invention also discloses a method for folding the filter material, wherein the folded filter material is stuffed layer by layer from the opening of the ring, when the number of layers reaches the requirement, the end sealing can be carried out at the opening of the ring, and then the filter material is compressed; and then sleeving one end of the annular filter material on the shell, forcibly filling the annular filter material into the shell from the other end, and finally welding an end cover of the shell to form the complete folded filter element.
The device can enable the soft film material to be more easily arranged in the framework material, the soft film material is not easy to deform in the process of being arranged in the framework material, the effective area of the material is increased, the filter material with higher pleat number can be conveniently processed into a filter element product, and the working efficiency of workers is improved.

Detailed Description
A device for assisting filter materials to be folded into filter elements comprises a conical central fixing column 1 for fixing an inner tube of the folded filter elements, a plurality of supporting rods 2 are uniformly arranged on an outer ring by taking the central fixing column 1 as a center, and the diameter of a ring enclosed by the supporting rods 2 is matched with the inner diameter of a shell of the folded filter elements; one end of the metal sheet 3 is fixed on one support rod 2 and forms a ring around the inner sides of a plurality of support rods 2, and the other end of the metal sheet 3 is either fixed or freely extended.
Wherein the width of the metal sheet 3 ranges from nine tenths to one half of the width of the filter material. The number of the support rods 2 is more than four. According to the different diameters of the folding filter element, two or more circles of support rods 2 are arranged.
The invention also discloses a method for folding the filter material, wherein the folded filter material 4 is stuffed layer by layer from the opening of the ring, when the number of layers reaches the requirement, the end sealing can be carried out at the opening of the ring, and then the filter material is compressed; and then sleeving one end of the annular filter material on the shell, forcibly filling the annular filter material into the shell from the other end, and finally welding an end cover of the shell to form the complete folded filter element.
A conical central fixing column 1 is arranged on a fixing frame, and an inner tube of the folding filter element is fixed, and the diameter of the inner tube is 25 mm. The internal diameter of the shell of the folding filter element is 60mm, so 6 support rods 2 are arranged according to a circle with the diameter of 60mm, the width of the filter element is 300mm, one section of a 250mm metal sheet 3 is fixed on one support rod 2, a ring is formed around the periphery along the inner side of the support rod 2, and the other section of the metal sheet is freely extended. The pleated filter material 4 is plugged into the opening of the ring layer by layer from the opening of the ring, the filter material can be compacted by a tool in the plugging process, after the number of layers reaches the requirement, the end is sealed at the opening of the ring, then the filter material is compressed, the annular filter material at one end of the shell is sleeved, the annular filter material is completely plugged into the shell by force from the other end, and finally the end cover of the shell is welded to form the complete folded filter element.
