Description

Technical Field

[0001] The invention relates to the technical field of rock wool production, and in particular to a pre-pressing device and method for rock wool production. Background Art

[0002] Rock wool, also known as mineral wool or rock wool, is a material made by melting natural rocks at high temperatures and then centrifugally or by blowing them into fibers. It has good thermal insulation, fireproofing, sound insulation and environmental protection properties and is commonly used in the construction industry and industry.

[0003] The production process of rock wool is roughly as follows: first select high-quality natural rock and flux mixture and put them into a high-temperature furnace, melt them at high temperature to form liquid magma, and then process them through centrifugation, blowing or spraying to form long and thin fibers. Then, collect the fibers and condense them together through a specific process to form a thick plate or felt-like material. Finally, cut them into different specifications and shapes according to needs; among them, in the process of fiber aggregation and solidification, the fibers need to be pre-pressed to pre-press the fluffy fibers into a plate-like structure. During pre-pressing, the fibers are gradually pre-pressed into shape by transmission through upper and lower pressure rollers. This pre-pressing form can only pre-press the fluffy fibers. After pre-pressing, the liquid content inside is relatively high, resulting in a longer subsequent solidification time, which affects the overall production efficiency of the rock wool.

[0016] A method for using a pre-pressing device for rock wool production comprises the following steps:

[0017] Step 1: connecting the excess waste heat in the high-temperature furnace used to melt the natural rock and flux mixture through the output port of the heat transfer pump system and the first flow guide pipe, the second flow guide pipe, the third flow guide pipe and the fourth flow guide pipe;

[0018] Step 2: After the rock wool raw materials are stacked, they are transferred to one end of the bottom support mechanism, and one of the feed rollers is controlled to rotate, and the transmission of the sprocket transmission group is coordinated to drive the other multiple feed rollers to rotate synchronously, so as to continuously support and transfer the pre-pressed rock wool raw materials;

[0019] The plurality of side fixed rollers on both sides are used for limiting, and the plurality of third auxiliary transport members and the plurality of fourth auxiliary transport members form an open structure at one end of the bottom support mechanism, so that the fluffy rock wool fibers can completely enter between the bottom support mechanism and the top pressure mechanism;

[0020] Step 3: Before entering the plurality of second auxiliary transport parts for pre-pressing, control the telescopic cylinder to telescopically drive the side pressure bracket to reciprocate horizontally, thereby squeezing the side end of the rock wool raw material through the side pressure bracket, so that the side end of the rock wool raw material is automatically squeezed into the inner position of the rock wool raw material, preventing the rock wool raw material at the side end from overflowing and causing resource waste;

[0021] The fluffy rock wool fibers are gradually moved to the bottom of the third auxiliary transport pieces and the fourth auxiliary transport pieces, and the upper end of the fluffy rock wool fibers are transmitted and squeezed in coordination with the rotation of the second auxiliary transport piece, so that the rock wool fibers are automatically and gradually pre-pressed and formed;

[0022] When the rock wool raw material is continuously supported, transmitted and pre-pressed, the heat transfer pump system is controlled to start, and the remaining waste heat flow in the high-temperature furnace is introduced into the feed rollers corresponding to the first auxiliary feed piece, the second auxiliary feed piece, the third auxiliary feed piece and the fourth auxiliary feed piece through the first guide pipe, the second guide pipe, the third guide pipe, the fourth guide pipe and the connecting elbow pipe. Since an outer casing with a drainage opening is provided, the heat flow in the feed roller is evenly discharged through the slow flow bin and the drainage opening, and is introduced into the rock wool raw material that is continuously supported, transmitted and pre-pressed, so as to perform primary drying treatment on the liquid substance in the rock wool raw material, thereby reducing the subsequent curing time;

[0023] Among them, the bottom baffle and the top baffle can limit the side ends of the rock wool raw materials during pre-compression, so as to prevent the rock wool raw materials from overflowing during the side pre-compression and causing blockage and entanglement of the feed roller.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. By setting up a bottom support mechanism and using a top pressure mechanism, the rock wool raw materials to be pre-pressed can be continuously supported and transmitted for pre-pressing. At the same time, the remaining waste heat flow in the high-temperature furnace can be introduced into the rock wool raw materials that are being continuously supported and transmitted for pre-pressing, and the liquid substances in the rock wool raw materials can be primarily dried, thereby reducing the subsequent curing time and improving the overall processing efficiency of the rock wool raw materials.

[0026] 2. By setting up a side pressure mechanism, the side pressure bracket is driven to move back and forth horizontally to squeeze the side end of the rock wool raw material, so that the side end of the rock wool raw material is automatically squeezed into the inner position of the rock wool raw material, preventing the rock wool raw material at the side end from overflowing and causing waste of resources, and increasing the compactness of the subsequent pre-compression of the rock wool, thereby improving the overall processing quality of the rock wool.

[0027] 3. By setting a side fixing mechanism, the stacked rock wool raw materials are limited, so that the rock wool raw materials can completely enter between the bottom support mechanism and the top pressure mechanism, and the rock wool raw materials are effectively pre-pressed, further improving the overall processing quality of the rock wool.

[0028] 4. By setting the bottom baffle and the top baffle, the rock wool raw material can be limited at the side during pre-compression to prevent the rock wool raw material from overflowing during pre-compression at the side, causing blockage and entanglement of the feed roller.

[0062] When the rock wool raw material is continuously supported, transmitted and pre-pressed, the heat transfer pump system is controlled to start, and the remaining waste heat flow in the high-temperature furnace is introduced into the feed roller 64 corresponding to the first auxiliary feed piece 6, the second auxiliary feed piece 311, the third auxiliary feed piece 321 and the fourth auxiliary feed piece 331 through the first guide pipe 22, the second guide pipe 313, the third guide pipe 322 and the fourth guide pipe 332 and the first guide branch pipe 221, the second guide branch pipe 314, the third guide branch pipe 323, the fourth guide branch pipe 333, and the connecting elbow pipe 67. Since the outer casing 62 with the drainage opening 601 is provided, the heat flow in the feed roller 64 is evenly discharged through the slow flow bin 602 and the drainage opening 601, and is introduced into the rock wool raw material that is continuously supported, transmitted and pre-pressed, so as to perform primary drying treatment on the liquid substance in the rock wool raw material and reduce the subsequent curing time;

[0063] Among them, the bottom baffle 23 and the top baffle 312 can limit the side ends of the rock wool raw material during pre-pressing, so as to prevent the rock wool raw material from overflowing during pre-pressing and causing blockage and entanglement of the feed roller 64.
