In existing technologies, it is difficult to effectively remove small impurities from waste oil during waste oil regeneration filtration, resulting in poor waste oil regeneration quality.
A material formula for a waste oil recycling filter cartridge made of pulp is adopted, which includes virgin wood pulp paper, adhesive materials, long-staple cotton and cotton nylon, etc. By controlling the material ratio and the use of adhesive materials, a filter cartridge with small pores is formed to filter out smaller impurities in waste oil.
It effectively filters solid waste larger than 3μm from waste oil, improving the quality of waste oil regeneration. In particular, impurities larger than 0.8μm are stored on the filter element, increasing the purity of the regenerated waste oil.
Abstract
Description
Technical Field
[0001] This invention relates to the field of filter element processing technology, and more specifically to a material formula for a pulp die-cast filter element for waste oil regeneration filtration. Background Technology
[0002] Statistical analysis shows that 80% of transmission failures are caused by oil contamination, primarily consisting of metals, dust, sand, and rubber. Oil degradation also produces impurities such as resin, oxide residues, and water. Therefore, to increase transmission safety and lifespan, frequent oil changes are necessary, generating substantial amounts of waste oil. Other industrial manufacturing processes also produce significant amounts of waste oil, which needs to be filtered and recycled to effectively protect the environment. However, current waste oil recycling technologies only filter out larger impurities using sieves, resulting in poor-quality recycled oil.
[0003] Therefore, how to provide a material formulation for a pulp die-cast filter element for waste oil regeneration that can filter out smaller impurities in waste oil and effectively improve the quality of the regenerated waste oil is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention
[0004] In view of this, the present invention provides a material formulation for a pulp die-casting filter element for waste oil regeneration filtration, aiming to solve the problems in the background art mentioned above, to filter out smaller impurities in waste oil, and to improve the quality of waste oil after regeneration.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a material formula for a pulp die-casting filter element for waste oil regeneration filtration, wherein the material formula for the pulp die-casting filter element for waste oil regeneration filtration comprises, by weight, the following: 60-95 parts of virgin wood pulp paper, 5-25 parts of adhesive material, 10-25 parts of long-staple cotton, 15-35 parts of cotton nylon velvet, 15-30 parts of environmentally friendly adhesive, and 250-350 parts of water.
[0006] Furthermore, the proportions of each raw material are as follows: 95 parts virgin wood pulp paper, 15 parts adhesive material, 15 parts long-staple cotton, 25 parts cotton nylon, 30 parts environmentally friendly adhesive, and 300 parts water.
[0007] Furthermore, the proportions of each raw material are as follows: 70 parts virgin wood pulp paper, 25 parts adhesive material, 25 parts long-staple cotton, 15 parts cotton nylon, 15 parts environmentally friendly adhesive, and 330 parts water.
[0008] Furthermore, the adhesive material is wood cellulose.
[0009] Furthermore, the adhesive material is polyamine.
[0010] Furthermore, the adhesive material is a polyurethane adhesive.
[0011] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a material formula for a pulp die-casting filter element for waste oil regeneration filtration. By setting adhesive materials and environmentally friendly adhesives to bond virgin wood pulp paper, long-staple cotton, and cotton nylon, the virgin wood pulp paper, long-staple cotton, and cotton nylon can be die-cast and fixed to form a filter element. This filter element has small gaps, allowing pure machine oil to pass through, while impurities in waste oil can be separated out, thereby achieving filtration of smaller impurities in waste oil and improving the quality of waste oil after regeneration. Attached Figure Description
[0012] none Detailed Implementation
[0013] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0014] This invention discloses a material formula for a pulp-cast filter element used in waste oil regeneration filtration. The material formula for the pulp-cast filter element includes, by weight, the following components: The composition consists of 60-95 parts virgin wood pulp paper, 5-25 parts adhesive material, 10-25 parts long-staple cotton, 15-35 parts cotton-nylon blend, 15-30 parts environmentally friendly adhesive, and 250-350 parts water. In this embodiment, the porosity of the filter element after die-casting can be controlled by adjusting the proportions of virgin wood pulp paper. A higher proportion of virgin wood pulp paper results in smaller pores, while a lower proportion results in larger pores. After mixing and die-casting, water will be partially extracted into the die-cast filter element. Higher contents of long-staple cotton and cotton-nylon blend result in smaller pores, and vice versa. In use, by controlling the precise proportions, filter elements with pore sizes of 3μm-60μm can be die-cast.
[0015] By bonding virgin wood pulp paper, long-staple cotton, and cotton nylon with adhesive materials and environmentally friendly glue, the virgin wood pulp paper, long-staple cotton, and cotton nylon can be die-cast and fixed to form a filter element. This filter element has small gaps, allowing pure machine oil to pass through while separating impurities in waste oil. This enables the filtration of smaller impurities in waste oil. In use, it can filter solid waste larger than 3μm from waste oil. 98.7% of the solid waste in waste oil is greater than or equal to 3μm, and 50% of impurities larger than 0.8μm can be stored on the filter element as it passes through, thus improving the quality of the recycled waste oil.
[0016] Virgin wood pulp paper is made from high-quality virgin wood through pulping, cooking, and other processes. It is characterized by its fine texture, softness, smooth surface, and good toughness, and it tears easily without leaving burrs or paper dust. Inferior products may contain residual fluorescent whitening agents and have a rough, porous texture with many holes and poor tensile strength, leaving paper dust when wiped and affecting usability.
[0017] The environmentally friendly adhesive is a recycled adhesive that is pollution-free, radiation-free, non-permeable, and free of substances harmful to the human body. It can effectively increase the safety of the production process of this formula and the safety of the filter cartridges produced by this formula.
[0018] In this embodiment, the adhesive material includes one or a combination of at least two of wood cellulose, polyamine, and polyurethane adhesives.
[0019] To illustrate that the filter element produced by the material formulation of the waste oil regeneration filter pulp die-casting filter element provided by the present invention can achieve good filtration effect, the following practical example is used for illustration: Example 1
[0020] In this embodiment, the proportions of each raw material are as follows: 95 parts of virgin wood pulp paper, 15 parts of adhesive material, 15 parts of long-staple cotton, 25 parts of cotton nylon, 30 parts of environmentally friendly adhesive, and 300 parts of water; in this embodiment, the pore size of the die-cast filter element is 58μm.
