Problems solved by technology

In addition, coffee machines, tofu machines, fruit juice machines, and oil presses generally use filter materials such as stainless steel mesh, cloth, and paper. Although these filter elements can play a certain role in filtering, they cannot filter very cleanly, that is, they cannot Completely separate the two-phase objects, resulting in poor drinking taste and poor appearance of the liquid part

Embodiment 1

[0036] This embodiment provides a kind of ceramic filter, and this filter is made up of several ceramic granules, and several micropores are all formed inside the ceramic granules and between the adjacent ceramic granules, and the pore size inside the ceramic granules is 0.5-10.5 μm, The diameter of the ceramic particles is 0.02-2.5 mm; the average value of the micropores between adjacent ceramic particles is 10-60 μm.

[0037] Wherein, the shape of the ceramic particle is a rhombus, ellipsoid, cuboid, cube or cylinder; the ceramic particle is a mixture of silicon carbide, feldspar powder, quartz powder and kaolin.

Embodiment 2

[0039] This embodiment provides a method for preparing a ceramic filter, at least including the following steps:

[0040] The first step is to mix raw materials: mix silicon carbide, feldspar powder, quartz powder, kaolin, and wood chips according to the mass ratio of (0.1-1): (0.2-5): (0.4-7): 1: (0.01-0.1) Evenly, then add a small amount of water so that the dry powder will not fly randomly, and keep the humidity of the raw material between 5%RH-40%RH, it can not become liquid, and the raw material mixture is obtained;

[0041] The second step, shaping: first use clay or plaster to make the required size and shape of the product through carving or plastic 3D printing;

[0042] The third step, solidification: use silica gel to make a soft mold according to the product shape (the soft mold is easy to disassemble the semi-finished product), and then set a plaster mold outside the soft mold (easy to solidify), and put the raw material mixture obtained in the first step into the ...

Embodiment 3

[0062] This embodiment provides a kind of ceramic filter of the present invention in soybean milk machine, coffee machine, teapot, tea set, tea tofu machine, fruit juice machine, rice washing device, vegetable washing device, fruit bowl, tea maker, hot pot bottom material separation , halogen separator, oil press, brewing equipment, plating solution precious metal separation equipment, industrial oil refining equipment, building ventilation equipment, environmental protection pool filtration equipment, battery electrolyte decomposition and filtration equipment, chemical solid and liquid primary separation or secondary separation equipment, Application in industrial sound insulation equipment and breathable products.

Abstract

The invention belongs to the technical field of ceramic filter parts, and particularly relates to a ceramic filter. The filter is composed of several ceramic particles. Several micro pores are formedin the insides of ceramic particles and between adjacent ceramic particles, the size of the pores inside the ceramic particles is 0.5-10.5 micrometers, and the diameter of the ceramic particles is 0.02-2.5 mm; the average of the pores between the adjacent ceramic particles is 10-60 micrometers. Compared with the prior art, the plasticity is high, products of any size and specifications can be prepared, no any chemical additives are added, the ceramic filter is more environmentally friendly, the food grade of utensils can be achieved, the filtering speed is high, pressure from other equipment is not required, flowing gravitational force of liquid can be used for fully separating solid and liquid, meanwhile cleaning is convenient, solid stays on the surface of a microporous filtration element, and the ceramic filter can be cleaned by direct flushing.

Description

technical field [0001] The invention belongs to the technical field of ceramic filter elements, and in particular relates to a ceramic filter and its preparation method and application. Background technique [0002] There are various filter materials in the prior art. For example, the filter part used as a tea strainer is generally made of stainless steel, and some holes of uniform size are set on it by mechanical punching; The material is generally a porous netted paper or fiber material; the filter parts equipped with soybean milk machines are generally stainless steel porous filters and the like. In addition, coffee machines, tofu machines, fruit juice machines, and oil presses generally use filter materials such as stainless steel mesh, cloth, and paper. Although these filter elements can play a certain role in filtering, they cannot filter very cleanly, that is, they cannot The two-phase objects are completely separated, resulting in poor drinking taste and poor appear...
