Description

Technical Field

[0001] The utility model belongs to the technical field of rock wool production, and particularly relates to a flushing device for the side wall of a cotton collecting chamber in rock wool production. Background Art

[0002] Rock wool is an outstanding building thermal insulation material. Rock wool has properties such as heat preservation, sound absorption, heat insulation, fire prevention, and air permeability. As an inorganic non-combustible material, rock wool belongs to Class A non-combustible thermal insulation materials.

[0003] With the continuous expansion of rock wool production capacity, energy conservation and consumption reduction have become the top priorities for enterprise development. Rock wool products all use high-quality basalt, dolomite, etc. as the main raw materials. After being melted at a high temperature of over 1450°C, they are centrifuged into fibers at high speed by an internationally advanced four-axis centrifuge. At the same time, a certain amount of binder, dust-proof oil, and water-repellent agent are sprayed in, and then collected by a cotton collecting machine. Through the pendulum method process, they are then solidified and cut to form rock wool products of different specifications and uses.

[0004] During the rock wool production process, after the centrifuge forms fibers, they pass through the cotton collecting chamber and are collected by the cotton collecting machine. In this process, some fibers, slag balls, and binders will accumulate on both side walls of the cotton collecting chamber. Due to the relatively high temperature in the cotton collecting chamber, the accumulated substances will solidify within a few minutes to form water-insoluble substances, resulting in difficult cleaning. Some insoluble substances are at the gap between the mesh plate of the cotton collecting machine and the side wall, and at the same time, excessive scaling forms a mound, blocking the mesh plate and causing cotton to fall. The existing method for cleaning the side wall is during the period of pouring molten iron or shutting down the furnace for maintenance. Because the binder solidifies relatively quickly, it cannot be processed during production, and the effect is relatively poor. Content of the Utility Model

[0005] In order to overcome the deficiencies of the prior art, the utility model provides a flushing device for the side wall of a cotton collecting chamber in rock wool production, which includes a spraying mechanism arranged on the top of the cotton collecting machine. The spraying mechanism includes a water inlet pump and a water spraying pipeline connected thereto. It also includes a water return tank, a feeding centrifuge connected to the water return tank, and a cement block-making device and a binder preparation tank respectively connected to the feeding centrifuge.

[0006] Preferably, the water spraying pipeline of the spraying mechanism includes a water spraying pipe and spray heads on the water spraying pipe located inside the cotton collecting machine.

[0007] Further, the distance between the spray heads is 10 - 20 cm, the water outlet pressure is 2 - 5 kPa, and the angle between the spray heads and the side wall 9 of the cotton collecting chamber is 0 - 10 degrees.

[0008] The motor power of the water inlet screw pump is 5 - 20 kw.

[0009] Preferably, the water return tank is arranged at the bottom of the cotton collecting machine. The width of the water return tank is 1 - 20 cm, and a spiral feeding device is installed in the water return tank; as a typical embodiment, the spiral feeding device is a spiral auger.

[0010] In an embodiment of the present utility model, the blanking centrifuge is a flat scraper blanking centrifuge.

[0011] In an embodiment of the present utility model, the water inlet pump is a screw pump.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] The structure provided by the present utility model can ensure the cleanliness of the side wall of the cotton collecting chamber. At the same time, solid-liquid separation is carried out by using a scraper blanking centrifuge. The solid can be used to make bricks with cement as raw materials for the production line; the liquid can be used when preparing the binder. The design of this process solves the problems of glue and scale formation on both sides of the cotton collecting chamber in rock wool production, which ultimately affects the normal operation of the cotton collecting machine. At the same time, it avoids scale formation from blocking the mesh plate of the cotton collecting machine, resulting in cotton dropping and low cotton formation rate. This solution is convenient to use, has a simple structure, and all the flushing water is recycled. BRIEF DESCRIPTION OF THE DRAWINGS
