Problems solved by technology

[0004] At present, the production method of cement board is mainly molding by pressing machine. This production method is difficult to realize the production of multi-layer board. It is difficult to produce cement boards on similar assembly lines, let alone the production of lightweight multi-layer boards made of sludge and cement-based materials

Embodiment 1

[0042] Such as figure 1 A production line for forming cement-based composite river silt multi-layer boards is shown, including three-layer mounting frame, microwave processing equipment, core material mixer, first fabric mixer, second fabric mixer, core material hopper, first fabric hopper, Second fabric hopper and conveying and laying equipment;

[0043] The layer installation frame includes the first installation platform, the second installation platform and the third installation platform arranged in sequence from top to bottom; the microwave processing equipment is installed on the first installation platform; the core material mixer, the first fabric mixer and the second fabric mixer are all installed on the second installation platform; the feed ports of the core material hopper, the first fabric hopper and the second fabric hopper are all installed on the second installation platform; the conveying and laying equipment is installed on the third installation platform, a...

Embodiment 2

[0048] On the basis of Example 1, the following improvements have been further made: the feeding ends of the first pressing material spreading equipment, the second pressing material spreading equipment and the third pressing material spreading equipment are respectively provided with two vibrating rods, Each diameter is 20mm, the vibration amplitude is 20mm, and the vibration frequency is 150 times / minute, which helps the material flow evenly.

Embodiment 3

[0050] On the basis of Example 2, further improvements are made as follows: a leveling device is provided upstream of the second pressing and spreading device, and the feed end of the second pressing and spreading device is arranged upstream of the leveling device. Because the thickness of the core material layer is relatively thick, a screw leveling device is arranged upstream of the second pressing and spreading equipment.

[0051] Utilize above-mentioned production line, prepare cement-based composite river silt multi-layer board, comprise the following steps:

[0052] 1) Add cement (Albo 525 white cement) and water with a mass ratio of 3.33:1 to both the first fabric mixer and the second fabric mixer, and stir. The mixing speeds of the first fabric mixer and the second fabric mixer are both 350 revs / min, the single mixing time (stirring time of one feeding) of the first fabric mixer and the second fabric mixer is 4 minutes, gets cement mixture;

[0053] 2) Add river silt ...

Abstract

The invention discloses a production line and a molding method for forming cement-based composite river silt multilayer boards. The production line includes microwave processing equipment, a core material mixer, a first fabric mixer, a second fabric mixer, a core material hopper, a first fabric hopper, The second fabric hopper and conveying and laying equipment; the conveying and laying equipment includes a conveyor belt, and the first pressing and spreading equipment, the second pressing and spreading equipment, the third pressing and spreading equipment and leveling and scraping are arranged on the conveying belt equipment; the materials in the first and second fabric mixers are transported to the feed end of the first and second pressing and spreading equipment through the first and second fabric hoppers respectively; the materials in the core material mixer are transported to the The feed end of the second pressing and spreading equipment; the discharge port of the microwave processing equipment is connected to the feed port of the core material mixer. The invention improves the production efficiency and solves the problem of river dredging and mud treatment; the board obtained is light in weight, sound-proof and heat-proof, and has high strength and good weather resistance.

Description

technical field [0001] The invention relates to a production line and a molding method for forming cement-based composite river silt multilayer boards, belonging to the field of board preparation from river silt. Background technique [0002] River dredging projects are very common at present, and the disposal of the sludge from dredging has not been very satisfactory. The main method is incineration, but incineration requires corresponding power plants / cement plants, which pollutes the environment during transportation, and the transportation cost is high and polluting Risk, if the dredged sludge can be produced into products nearby, it will greatly improve the efficiency of river dredging and save costs. [0003] At present, the country is vigorously promoting prefabricated buildings in terms of building materials. In prefabricated buildings, partition walls, especially cement panels with decorative effects that can be used on exterior walls, are in great demand and have a...
