Problems solved by technology

[0003] Considering that the products produced by the traditional method have disadvantages such as poor fiber interweaving structure and uneven hardness, the patent document with the publication number CN1124192C discloses a "vacuum suction molding process for refractory fiber products", which is based on the traditional method. , using the negative pressure source on the top, the mold suction port is immersed in the material liquid to form the suction filter, the vacuum suction filter area adopts multi-cavity and multi-stage distributed settings, and the suction filter is also set in multi-layer superimposition, so as to make the negative The distribution of the press area is uniform and reasonable, eliminating the disadvantages of poor fiber interweaving structure and uneven hardness, and improving the overall structural performance and surface smoothness of the product
[0004] But above-mentioned method is mainly suitable for the refractory product of felt, plate class, can't be used for making the refractory product of tubular shape or energy-saving cover etc. that have the larger inner hole surface and the refractory shape of outer peripheral surface, and its main problem is that adsorption is uneven and Difficult to demould

Embodiment 1

[0025] A method for forming refractory fiber products, such as figure 2 , image 3 As shown, it includes a mold 2 that can rotate around a fixed axis and a pressure roller 1 that is rolled in cooperation with the mold 2. The mold 2 is provided with an adsorption surface 22, and several suction surfaces connected to a negative pressure source are distributed on the adsorption surface 22. Hole 23, follow the steps below:

[0026] 1) Watering—the mold 2 rotates forward, turns on the negative pressure source, and pours the prepared refractory fiber suspension slurry on the adsorption surface 22 of the mold 2; wherein, the refractory fiber suspension slurry The solvent water is separated by suction and 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, the refractor...

Embodiment 2

[0035] Such as figure 1 The above-mentioned special equipment for the forming method of refractory fiber products includes a rotating shaft 3 connected to the mold 2, and the air suction hole 23 on the mold 2 communicates with the filter tank 8 through the air suction channel 13 provided on the rotating shaft 3 , the filter tank 8 is connected with the vacuum pump 10, and the rotating shaft 3 is connected with the motor 11 through the gearbox 7; The sealed cavity 12 connected by the air channel 13, the sealed cavity 12 communicates with the water filter tank 8, and the rotating shaft 3 is sealed and connected with the rotating shaft seat 4 through the sealing ring 5; the above-mentioned filtered water tank 8 is provided with a drain tap, and a sink 9 is placed under the drain tap ; The motor 11, the gearbox 7 and the shaft seat 4 are installed on the frame 14.

[0036] In this embodiment, the vacuum pump 10 is the negative pressure source described in Embodiment 1.

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...
