Description

Technical Field

[0001] The present invention relates to the technical field of mud squeezing devices, and more specifically, to a mud squeezing device for producing energy-saving materials. Background Art

[0002] Mud extrusion devices are widely used in the production of energy-saving and thermal insulation materials, such as bricks, refractory materials, and furnace linings. The device primarily consists of a barrel and an extrusion screw. A motor drives the screw to rotate, and the screw's blades form a sealed cavity with the barrel's inner wall. The mud material moves axially under the propulsion of the blades. The depth of the screw groove gradually becomes shallower or the pitch decreases, compressing the mud material and gradually increasing the pressure. The high-pressure mud material is then extruded through a mold (die head) to form a continuous green body of a specific shape.

[0003] During the operation of the slurry extruder, the lining wears, and the degree of wear varies at different angles along the circumference due to the asymmetric flow of the slurry and the effects of centrifugal force and gravity. Furthermore, due to the varying degrees of slurry compression in the conveying, compression, and extrusion sections, the wear of the lining varies. Replacing the entire lining is costly, and replacing it entirely simply because a portion is severely worn and unusable is wasteful. Summary of the Invention

[0061] The cylinder 1 includes a cylinder body 1.3 with a bottom opening and a bottom cover 1.4 capable of closing the bottom opening. The first arc-shaped inner liner 4.1 has a first positioning hole 4.4, and the second arc-shaped inner liner 5.1 has a second positioning hole 5.4.

[0062] There are six mounting holes; the cross-section of each mounting hole is circular, and the angle between the axis of the mounting hole and a vertical plane passing through the axis of the extrusion screw is less than 10 degrees. The strip-shaped through-slot 1.5 is provided with three transparent baffles 1.6, each facing a rotating liner, with one end of the transparent baffle 1.6 flush with the side of one of the curved ridges 6.3, and the other end flush with the side of another curved ridge 6.3. The bottom opening is provided with two first strip ridges 1.3.1. The bottom cover 1.4 includes a curved bottom plate and two second strip ridges 1.4.1 fixedly connected to the bottom plate. The corresponding first and second strip ridges are fixedly connected by bolts and nuts. The barrel 1.3 is provided with an exhaust pipe 11. One of the second curved liners 5.1 of the intermediate fixed liner has a through-hole portion 5.5 connected to the exhaust pipe 11. The exhaust pipe 11 is connected to a vacuum unit.

[0063] Working principle: The mud squeezing device of the present application has fixed liners at two ends and two middle fixed liners, and the three rotating liners are limited by the two adjacent fixed liners, and under the drive of the gear, the gear can drive the arc-shaped tooth portion (the three arc-shaped tooth portions are combined into a gear ring), so that the gear can drive the rotating liner to rotate (the rotation can be set to rotate at a very small angle (for example, 10 degrees-120 degrees) every set time (for example, one day or one hour), so that the degree of wear of the rotating liner is basically consistent in the entire circumferential direction. And by opening the bottom cover (and loosening the locking bolts), the first arc-shaped liner and the second arc-shaped liner can be disassembled, so that the first arc-shaped liner, the second arc-shaped liner and the third arc-shaped liner can be replaced according to the module, so that the maintenance and replacement cost is low, maintenance is convenient, and maintenance is convenient.

[0064] The curved teeth are each provided with curved ridges on both sides, shielding and protecting them from mud (which is actually quite rare due to the stickiness of the mud material) entering the curved teeth through the gaps and becoming stuck. Furthermore, the contact head of the pressure sensor can abut the curved grooves, allowing the pressure sensor to detect changes in its readings (normally, the pressure sensor's readings remain constant as the liner rotates) and determine whether the liner is rotating normally or experiencing any anomalies.

[0065] Furthermore, the translation seat can translate, so as to observe the interior of the barrel along the entire length of the strip observation window, thereby collecting visual images to determine whether the rotating liner is working properly. Furthermore, during the mud squeezing process, even if a small amount of mud residue leaks from the gap of the modular liner to between the liner unit and the barrel, it will fall into the strip bottom box as the rotating liner rotates, so that whether the liner is working properly can be determined based on the amount of mud residue in the strip bottom box. In addition, when there is a lot of mud residue that hinders the image acquisition unit from acquiring images, the mud residue can be blown away (or sucked away) through the two pipe parts using a blowing device (or a negative pressure suction device), and the position of the transparent baffle just blocks the gear ring, so that when the mud residue is blown away or sucked away, the mud residue will not enter the space where the gear ring is located.

[0066] Although the present invention has been illustrated and described with respect to the preferred embodiments, it will be understood by those skilled in the art that various changes and modifications may be made to the present invention without departing from the scope of the present invention as defined by the claims.
