Embodiment 1

[0059] Manufacture of a device for the additive manufacturing of rigid insulation tile blanks, such as figure 1 shown. The device for additively manufacturing a rigid heat-insulating tile body includes a feeding system, a filter container, a drain pipe, a pressurizing device and an automatic control system (PLC controller, a first displacement sensor, a second displacement sensor, a pressure sensor and solenoid valve).

[0060] The filter container includes a peripheral wall, a bottom plate, a bottom net (30 mesh steel wire mesh), 3 lath-shaped reinforcing ribs arranged in parallel (through holes are provided on the reinforcing ribs) and a liquid collecting tank arranged below the reinforcing ribs. part, the liquid outlet of the liquid collection part communicates with the liquid discharge pipe, and the liquid discharge pipe includes a main liquid discharge pipe and a secondary liquid discharge pipe. Wherein, a pulley is arranged on the bottom plate, and a slide rail matched...

Embodiment 2

[0068] A device for additively manufacturing a rigid heat-insulating tile body was manufactured that was basically the same as in Example 1, except that the distance between the centers of every two adjacent through holes was 8mm.

[0069] The device in this example was used to manufacture the rigid heat-insulating tile body in the same manner as in Example 1, and the density test was carried out on the 7 layers of slurry included in the manufactured rigid heat-insulating tile body. The results are shown in Table 1 .

Embodiment 3

[0071] A device for additively manufacturing a rigid heat-insulating tile body was manufactured that was basically the same as in Example 1, except that the distance between the centers of every two adjacent through holes was 12 mm.

[0072] The device in this example was used to manufacture the rigid heat-insulating tile body in the same manner as in Example 1, and the density test was carried out on the 7 layers of slurry included in the manufactured rigid heat-insulating tile body. The results are shown in Table 1 .

Abstract

The invention relates to a device for additive manufacturing of rigid thermal insulation tile bodies. The device comprises a filter container capable of being operated to move in the horizontal direction, a liquid discharging pipe communicated with a liquid outlet of the liquid collecting part, a feeding system for feeding materials into the filter container as well as a pressurizing device located on one side of the spray head and used for pressurizing materials in the filter container, wherein the filter container comprises a bottom plate comprising openings in the peripheral walls and the middle, a bottom net at the lower part of an inner cavity defined by the peripheral walls, reinforcing ribs for supporting the bottom net and a liquid collecting part below the reinforcing ribs; the feeding system comprises a storage chamber, a feeding pipe, a spray head communicated with an outlet end of the feeding pipe and a perforated plate arranged below the spray head and having a hole array,holes in the hole array are through holes, and the through holes correspond to nozzles of the spray head and are used for supporting and fixing the nozzles; the pressurizing device comprises a pressure head, a pressure arm fixedly connected with the pressure head and a driving device for driving the pressure arm to vertically stretch and retract. The device can manufacture the rigid thermal insulation tile bodies with uniform density and accurate thickness and has the advantages of simple structure, low manufacturing cost and the like.

Description

technical field [0001] The invention belongs to the technical field of rigid heat-insulation tile manufacturing, and in particular relates to a device for additively manufacturing a rigid heat-insulation tile body. Background technique [0002] At present, there is a problem of uneven density in the manufacturing process of the rigid heat insulation tile body. [0003] The manufacturing process of rigid thermal insulation tiles generally includes placing the slurry containing short fibers and sintering aids in a container with filtering function to filter out the water in it, and then obtain the rigid thermal insulation tile green body (filter cake), and then The rigid thermal insulation tile body is dried and sintered in sequence to obtain the rigid thermal insulation tile; however, in this method, there will be uneven density of the rigid thermal insulation tile blank body in all directions, especially in the thickness direction, resulting in manufacturing There is anisot...
