Example Embodiment

[0024] Example 1:

[0025] A method for forming a refractory fiber product, as shown in Figures 2 and 3, includes a mold 2 that can rotate around a fixed axis and a pressure roller 1 that cooperates with the mold 2 to roll. The mold 2 is provided with an adsorption surface 22 for adsorption There are several suction holes 23 connected to the negative pressure source distributed on the surface 22, according to the following steps:

[0026] 1) Pouring-the mold 2 is turned forward, the negative pressure source is turned on, and the prepared refractory fiber suspension slurry is poured on the adsorption surface 22 of the mold 2; among them, the refractory fiber suspension slurry The solvent water is separated by suction filtration through a negative pressure source, and the refractory fiber mixture in the refractory fiber suspension slurry is adsorbed on the adsorption surface 22 of the mold 2;

[0027] 2) Forming——After pouring the refractory fiber suspension slurry for many times, t...

Abstract

The invention discloses a method for molding a refractory fiber product and special equipment thereof. With the method, filtering molding can be realized by rotating a mould and pouring a refractory fiber suspension material, even interlacement and absorption of the fiber can be ensured through manually selecting and regulating the pouring position timely; a bore surface of a molded product is molded depending on an absorption surface of the mould; the periphery of the molded product is molded through rolling of the periphery of a compression roller, thereby ensuring the specification of the appearance of the molded product; and rapping of the molded product can be conveniently realized through rotating the mould positively and negatively under the pressure of the compression roller, thereby avoiding the problem of rapping difficulty by the prior method. The technical proposal has the advantages of simple mould, convenient operation, high production efficiency, easy rapping, even interlacement of product fiber, good rupture strength and the like.

Description

technical field [0001] The invention belongs to the technical field of forming refractory fiber products, and in particular relates to a forming method and special equipment for manufacturing a refractory fiber product in the shape of a spiral body with an inner hole. Background technique [0002] When manufacturing refractory fiber products in the prior art, the vacuum suction filter molding process is usually adopted. The traditional method is: in the negative pressure source for suction filter-mold combination, the negative pressure source is at the bottom, and there is a layer of suction filter mesh in the middle. Finally, a mold is used; the process is: using refractory fiber as the main raw material, adding a certain amount of binder to make a suspension slurry, pouring it into the mold from top to bottom, and separating the solvent water through vacuum suction filtration, refractory fiber The mixture is adsorbed in a mold of a certain shape, and after drying, felts, b...
