Problems solved by technology

[0003] The current domestic production of smoke filter elements can be summed up in three aspects of technical defects: first, the product design structure shape is unreasonable; second, there are safety hazards in the selection of materials; , among them, the large amount of small canisters used by the people, because of their small installation size, the contradiction is particularly prominent
[0012] The original "folded and bonded combination" design structure of the smoke filter element was a realistic choice before the reform and opening up with backward economy and technology, due to the abundance of low-cost labor
However, this kind of design can only be completed by manual labor, which limits the adoption of many modern technological means, resulting in low efficiency, waste of resources, and a lot of industrial waste.
Product quality control is difficult. With the rising labor costs, the development of enterprises is difficult.

Embodiment

[0059] Such as Figure 1-Figure 3 As shown, a filter element provided in this embodiment includes a smoke filter element body 1 placed in the canister. function, the equation of its revolving generatrix is: y=f(x); and each mass point on the entity of the smoke filter element body 1 is all on the concentric circles that rotate around the central axis of the canister cylinder, that is, the OX axis; then according to The following formula between the number n of corrugations of the smoke filter element body 1 and the inner diameter of the tank finally determines the number n of corrugations of the smoke filter element body 1:

[0060]

[0061] in:

[0062] D—the outer diameter of the smoke filter element body 1, which is equal to the inner diameter of the canister;

[0063] d—the diameter of the process space reserved in the middle part of the smoke filter element body 1;

[0064] t—the fluctuating cycle value of the 1st rotary busbar of the smoke filter element body, that...

Abstract

The invention discloses a filtering element and a preparation method of the filtering element. The filtering element comprises a smoke filtering element body arranged in a toxicant filtering tank, wherein the smoke filtering element body is in a shape of a space revolution surface; a revolution bus is a digital function of a sine wave; an equation of the revolution bus is as follows: y is equal to f(x); all particles on an entity of the body are located on a concentric circle rotating around a cylindrical central axis, namely an OX axis, of the toxicant filtering tank; and therefore, a dimension of a smoke filtering element or a forming grinding tool of the smoke filtering element is calculated according to the following formula which is as shown in the specification during a detailed design. According to the filtering element and the preparation method of the filtering element, the filtering element is convenient to machine, good in stability, ageing resistance, corrosion resistance and water resistance, and low in cost, and improves and increases efficiency and a safety degree of a prefilter.

Description

technical field [0001] The invention relates to an anti-virus smoke filter element, in particular to a filter element and a preparation method thereof. Background technique [0002] The anti-virus smoke filter element (commonly known as smoke filter paper or smoke filter layer in the industry) is a necessary pre-basic filter element for filtering respiratory protective equipment. Its function is to greatly reduce the transmission rate of inhaled air poisoning smoke first, so as to ensure that the special filter material filled thereafter can fully exert its effective effect. The design of the smoke filter element should form the largest effective flow area and minimize the inhalation resistance under the premise of ensuring the transmission rate reaches the standard, so as to meet the respiratory physiological safety requirements of the wearer. Therefore, the materials selected for design should be non-toxic, harmless and non-irritating, and maintain physical and chemical s...
