This process is to carry out process compounding of hazardous waste fly ash, slag coarse sand, talc, coal gangue, dolomite, basalt and other additives to produce ceramic fiber technology.

[0003] Most domestic equipment manufacturers generally adopt bamboo plate linkage pre-pressing or pressure roller linkage pre-pressing molding in the stage of fiber collection to cotton paving and shaping. The bamboo plate linkage pre-pressing has a good effect, but the damage rate is very high and it is difficult to replace. The pressure roller linkage pre-pressing has a poor effect and is prone to cotton squeezing and production stoppage, but it is convenient for maintenance and replacement. According to the current situation, a new pre-pressing system is designed to make the pre-pressed cotton paving flat and smooth, and there is no cotton squeezing or cotton breaking.

[0004] Therefore, we propose a fiber pre-pressing and leveling device. Content of the Utility Model

[0009] As a preferred mode of the utility model, the side plates form a rectangular plate structure. Ear plates are fixedly installed on the same side wall surfaces of the side plates and the frame. A lead screw is threadedly connected to the ear plate on the side of the side plate. The lead screw is rotatably connected to the other ear plate. A motor is fixedly installed at the bottom of the ear plate on the side wall of the frame. The lead screw is fixedly connected to the output shaft of the motor.

[0010] As a preferred embodiment of the present utility model, the first extrusion rollers are linearly distributed, the guiding rollers are distributed along an arc track, the uppermost guiding roller is located obliquely above the first extrusion rollers, and the lowermost guiding roller is on the same axis as the first extrusion rollers.

[0011] As a preferred embodiment of the present utility model, cavities are formed inside both the guiding rollers and the first extrusion rollers. A water tank is provided on the side wall of the side plate. A water pipe is fixedly installed at the end of the first extrusion roller, and the water pipe is communicated with the water tank.

[0017] 1. For this fiber pre-pressing and leveling device, the alligator mouth system formed by multiple guiding rollers can press and collect high-thickness fibers into primary felts that basically meet the model requirements. The kinetic mechanical force is used to forcibly collect and feed the materials. The back-end shaping and pressing formed by multiple first extrusion rollers and second extrusion rollers adopt water cooling, so that the upper fibers are forcibly cooled from the high-temperature stage, which is more conducive to surface shaping without interfering with the middle fibers. Similarly, the upper and lower clamping kinetic energy is used to forcibly feed the materials into the needle punching machine, and the squeezing phenomenon of cotton will not be formed due to the resistance brought by the up and down needle punching of the needle punching machine, reducing the failure shutdown rate and lowering the production cost per ton.

[0032] like Figure 2 As shown, the side plate 11 forms a rectangular plate structure, and the same side walls of the side plate 11 and the frame 10 are fixedly installed with ear plates 20, the ear plate 20 on the side of the side plate 11 is threadedly connected with a screw rod 21, the screw rod 21 is rotatably connected to the other ear plate 20, and a motor is fixedly installed at the bottom of the ear plate 20 on the side wall of the frame 10, and the screw rod 21 is fixedly connected to the motor output shaft.
