Technical Field
The utility model relates to a compound explosion-proof filter core.
Background
The conventional filter element is only provided with a single folded filter element outside the central rod, and under special working conditions of high temperature, high pressure, strong corrosion, strong oxidation and the like, the folded structure of the conventional filter element is easily damaged, particularly, the edge sealing part is easily burst, so that the filter element is leaked, and a great deal of inconvenience and economic loss are brought to customers.
SUMMERY OF THE UTILITY MODEL
The utility model discloses shortcoming to prior art exists provides a compound explosion-proof filter core, makes the whole leakage that can not take place of filter core, improves the stability in use, avoids causing customer's economic loss.
Therefore, the utility model adopts the following technical proposal: the utility model provides a compound explosion-proof filter core, includes well core rod, its characterized in that well core rod's outside sets gradually security personnel filter layer, folding filter layer and exoskeleton, exoskeleton both ends set up the end cover, security personnel filter layer be the winding arrangement filter membrane, folding filter layer be the folding arrangement filter membrane, the material of winding arrangement filter membrane and folding arrangement filter membrane unanimous, the filtration efficiency of winding arrangement filter membrane be not less than the folding arrangement filter membrane.
The precision of the filter membrane with the winding structure is smaller than that of the filter membrane with the folding structure, and the filter membrane with the winding structure is of a winding three-layer structure.
The winding structure filter membrane and the folding structure filter membrane are subjected to end welding in a hot melting welding mode.
The folding structure filter membrane adjusts folding parameters according to the outer diameter of the winding structure filter membrane, and is tightly arranged between the outer framework and the security filter layer.
The central rod is a high-strength injection molding part or a metal punching pipe.
The utility model discloses increasing winding arrangement in that the filter core is inside and as security personnel filter layer, making winding arrangement filtration efficiency unanimous with beta structure, even beta structure takes place to burst, winding arrangement still can play the filterable effect of security personnel, and the filter core is whole can not take place to leak to avoid causing customer's economic loss.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The composite type explosion-proof filter element shown in fig. 1-2 comprises a central rod 5, wherein a security filter layer 4, a folding filter layer 3 and an outer framework 2 are sequentially arranged outside the central rod, end covers 1 are arranged at two ends of the outer framework, the security filter layer is a winding structure filter membrane, the folding filter layer is a folding structure filter membrane, the winding structure filter membrane and the folding structure filter membrane are made of the same material, and the filtering efficiency of the winding structure filter membrane is not less than that of the folding structure filter membrane.
The precision of the filter membrane with the winding structure is smaller than that of the filter membrane with the folding structure, and the filter membrane with the winding structure is of a winding three-layer structure. The end welding is carried out on the winding structure filter membrane and the folding structure filter membrane in a hot melting welding mode. The folded structure filter membrane adjusts the folding parameter according to the external diameter of winding structure filter membrane, and the folded structure filter membrane is closely installed in the middle of outer skeleton and security personnel filter layer. The central rod is a high-strength injection molding part or a metal punching pipe.
The utility model discloses the implementation as follows: through verifying, winding structure filter membrane adopts the same material filter membrane that reduces a precision level than the beta structure filter membrane, and 3 layers of winding can reach the same filtration efficiency with beta structure. And determining the folding height of the folding structure according to the outer diameter of the winding structure, debugging folding parameters to assemble the winding structure and the folding structure together, and performing end welding in a hot melting welding mode. 100% integrity test of filter element welded at opposite ends
The utility model adopts the winding structure as the security filter, which can avoid leakage and economic loss after the folding structure bursts; the filtration efficiency of the winding part is consistent with that of the folding part, and the overall filtration effect of the filter element is not influenced; and (4) carrying out integrity test on 100% of the filter element to ensure that the requirement of a customer is met.
The utility model discloses increasing winding arrangement in that the filter core is inside and as security personnel filter layer, making winding arrangement filtration efficiency unanimous with beta structure, even beta structure takes place to burst, winding arrangement still can play the filterable effect of security personnel, and the filter core is whole can not take place to leak to avoid causing customer's economic loss.
The above description is only an example of the preferred embodiment of the present invention, and is not intended to limit the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
