Description

Technical Field

[0001] The utility model relates to the technical field of rock wool production, in particular to a homogenizer and a rock wool injection device. Background Art

[0002] Rock wool is a building material with excellent sound insulation, heat preservation, fireproof and other properties. It is widely used in construction, shipbuilding, petrochemical and other fields. The main raw materials of rock wool are basalt and quartz sand, and some additives and binders need to be added. During production, basalt and quartz sand are first mixed in a certain proportion, and appropriate amounts of additives and binders are added and stirred evenly. The mixed raw materials are sent to a high-temperature electric furnace for melting treatment. At high temperature, the raw materials gradually melt and form a liquid substance. Finally, the liquid substance is sprayed out through a rotary spinneret, and it is stretched into slender fibers at the nozzle with a high-speed airflow.

[0003] In the existing injection device for producing rock wool, the rotary spinner is directly connected to the liquid mortar, and it is inevitable that some mortar raw materials will be unevenly distributed after melting, resulting in uneven quality of the injected fibrous rock wool. Therefore, it is necessary to improve the structure of the existing injection device. Utility Model Content

[0004] The utility model aims to propose a homogenizer and a rock wool injection device to solve the deficiencies of the prior art, so as to make the molten mortar raw materials more uniform and improve the quality of the injection-molded rock wool.

[0005] The technical solution to achieve the purpose of this utility model is:

[0006] A homogenizer comprises a distributor, a first slurry feeder, a diffuser and a second slurry feeder which are arranged from bottom to top and are sequentially connected to each other. The distributor is provided with a plurality of distribution pipes, and a plurality of diffusion pipes which are evenly distributed in the diffuser are greater in number than the number of the distribution pipes.

[0007] Furthermore, the number of the distribution pipes is N1, the number of the diffusion pipes is N2, and N2=(5-30)N1 is satisfied.

[0008] Furthermore, the diffuser is a conical structure with an inner diameter at the upper end being larger than an outer diameter at the lower end.

[0009] Furthermore, the diffusion tubes are distributed in multiple rows and columns, and the diffusion tubes in adjacent rows are staggered.

[0010] Furthermore, the upper end of the distributor and the upper and lower ends of the first slurry feeder, the diffuser and the second slurry feeder are all provided with mounting plates extending outwards, and adjacent mounting plates are detachably fixedly connected by bolts.

[0011] Furthermore, a plurality of reinforcing ribs are evenly distributed on the outer wall of the second pulp feeder.

[0012] Furthermore, the outer wall of the lower end of the distribution pipe is provided with a mounting thread.

[0013] A rock wool injection device comprises a base and a rotary spinneret fixedly mounted on the base, wherein the above-mentioned homogenizer is installed at the inlet of the rotary spinneret, and a distribution pipe of the homogenizer is connected to molten mortar raw materials.

[0016] (2) The number of diffusion tubes of the utility model is 5 to 30 times the number of distribution tubes, which can ensure uniform slurry and prevent congestion in the flow channel due to excessive number of diffusion tubes, thereby affecting the flow rate of the mortar.

[0018] (4) The diffuser tubes in adjacent rows of the utility model are staggered, so that the diffuser tubes are arranged more compactly and the diffuser has a more compact appearance.

[0019] (5) The utility model realizes a detachable connection between the distributor, the first slurry feeder, the diffuser and the second slurry feeder through a mounting plate and a bolt structure, which not only ensures a firm connection but also facilitates assembly, disassembly and maintenance.

[0020] (6) The outer wall of the second pulp feeder of the utility model is additionally provided with reinforcing plate ribs to improve the structural strength of the second pulp feeder.

[0021] (7) The outer wall of the lower end of the distribution pipe of the utility model is provided with a mounting thread, which makes it easier to connect the pipeline.

[0036] (Example 1)

[0037] like Figures 1 to 5 The rock wool injection device shown comprises a symmetrically arranged base 1 and a rotary spinneret 2 fixedly mounted between the two bases 1, and a homogenizer 3 is installed at the bottom entrance of the rotary spinneret 2. The homogenizer 3 comprises a distributor 3-1, a first slurry feeder 3-2, a diffuser 3-3 and a second slurry feeder 3-4 arranged from bottom to top and sequentially connected to each other, the distributor 3-1 is provided with a plurality of distribution pipes 3-1-1, each distribution pipe 3-1-1 is connected to the molten mortar raw material, a plurality of diffusion pipes 3-3-1 are uniformly distributed in the diffuser 3-3, and the number of diffusion pipes 3-3-1 is greater than the number of distribution pipes 3-1-1, and the mortar transported from the distribution pipe 3-1-1 to the first slurry feeder 3-2 is re-homogenized, so that the mortar raw materials flowing into the second slurry feeder 3-4 are more evenly fused, thereby improving the quality of the rock wool injected by the rotary spinneret 2.

[0038] Specifically, the distribution pipe 3-1-1 is evenly provided with 7 slurry inlet pipes along the length direction of the distributor 3-1. The diffusion pipes 3-3-1 are distributed in multiple rows and columns. In this embodiment, four rows are provided, and the diffusion pipes 3-3-1 in adjacent rows are staggered, so that the arrangement between the diffusion pipes 3-3-1 is more compact, and the diffuser 3-3 is more compact. The number of diffusion pipes 3-3-1 in the first and third rows is 31, and the number of diffusion pipes 3-3-1 in the second and fourth rows is 30, and the total number is 122, which is about 17 times the number of distribution pipes, which can ensure uniform slurry and will not cause congestion in the flow channel due to too many diffusion pipes 3-3-1, affecting the flow rate of the mortar.

[0039] The diffuser 3-3-1 is a conical structure with an inner diameter at the upper end larger than an outer diameter at the lower end, wherein the inner diameter D1 at the upper end of the diffuser is 50 mm, and the inner diameter D2 at the lower end is 40 mm, so that the mortar flowing through the diffuser 3-3-1 is naturally diffused, ensuring smooth flow of the mortar.

[0040] In order to facilitate assembly, the upper end of the distributor 3-1 of this embodiment and the upper and lower ends of the first slurry feeder 3-2, the diffuser 3-3 and the second slurry feeder 3-4 are all provided with mounting plates 4 extending outward, and adjacent mounting plates 4 are detachably fixedly connected by bolts. In addition, the outer wall of the lower end of the distribution pipe 3-1-1 is provided with mounting threads, which is more convenient for connecting the pipeline. In order to improve the structural strength, the outer wall of the second slurry feeder 3-4 of this embodiment is also evenly distributed with a plurality of reinforcing plate ribs 3-4-1.
