Description

Technical Field

[0001] This utility model relates to the field of material leveling equipment technology, and in particular to a tailings leveling device. Background Technology

[0002] Material leveling is a common operation in industrial production, aimed at flattening and spreading out excessively piled materials for use in subsequent processes. For example, in a continuous cooking production line of a chemical pulping plant, the wastewater from washing and filtering fibrous materials such as bagasse and eucalyptus shavings contains a large amount of fine fibers, sand, and other solid residues. The production process requires this fine fiber material to be filtered and pressed using a belt filter press for recycling. Currently, the tailings from the filter screen, due to insufficient moisture content, cannot naturally spread on the filter press screen. The tailings clump together in small piles as they are pressed and concentrated, easily causing uneven stress on the press rollers and filter screen, leading to damage to these components and uneven moisture content in the pressed tailings. Therefore, it is necessary to invent a tailings leveling device that can be integrated into the continuous cooking production line of a chemical pulping plant to solve these problems. Summary of the Invention

[0003] The purpose of this utility model is to provide a tailings leveling device to address the above-mentioned problems, thereby solving the technical problem that the traditional continuous cooking production line of chemical pulping plants does not have a tailings leveling device, which easily leads to uneven stress on the press rollers and filter screens, easy damage to the press rollers and filter screens, and uneven moisture content of the tailings after pressing.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A tailings leveling device includes a housing, a distributing screw shaft, leveling rollers, a drive unit, and a transmission structure. The upper part of the housing is provided with a feed inlet, and the lower part of the housing is provided with a discharge outlet. The distributing screw shaft is horizontally and rotatably mounted inside the housing, and the leveling rollers are parallel to the distributing screw shaft and rotatably mounted inside the housing. The drive unit drives the distributing screw shaft and the leveling rollers to rotate through the transmission structure.

[0005] Furthermore, spiral plates are respectively provided on the outer periphery of both ends of the material distribution spiral shaft, and the spiral plates at both ends have opposite spiral directions.

[0006] Furthermore, several flat plates are evenly distributed on the outer peripheral wall of the flat roller, and the flat plates extend outward in a radial direction.

[0007] Furthermore, it also includes a mounting bracket, which is fixedly mounted on the outer wall of the housing, and the drive device is mounted on the mounting bracket.

[0008] Furthermore, the transmission structure includes a first chain transmission structure and a second chain transmission structure. The driving device drives the material distribution screw shaft to rotate through the first chain transmission structure, and the material distribution screw shaft is linked with the flat roller through the second chain transmission structure.

[0009] Furthermore, the driving device is a cycloidal pinwheel reducer motor.

[0010] Furthermore, it also includes an adjustable gate, with a side opening provided on the rear side of the housing, and the adjustable gate is installed on the rear side of the housing in an adjustable height.

[0011] Furthermore, an installation rod is provided on the upper part of the side opening, and several adjusting screws are provided on the upper part of the adjustable gate plate. The adjusting screws are mounted on the installation rod by several nuts.

[0012] Due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: 1. This utility model is used in conjunction with a continuous cooking production line in a chemical pulping plant. The tailings enter through the feed inlet at the top of the machine casing. The drive unit starts, and the first chain transmission structure rotates the distributing screw shaft. Because the spiral plates at both ends of the distributing screw shaft rotate in opposite directions, they evenly convey the incoming tailings to both sides of the feed inlet. Simultaneously, the distributing screw shaft drives the leveling rollers to rotate through a second chain transmission structure. The leveling plates evenly distributed on the outer circumference of the leveling rollers extend radially outwards, leveling the tailings during rotation. Through the combined action of the distributing screw shaft and the leveling rollers, the processed tailings are discharged smoothly from the outlet at the bottom of the machine casing. This solves the technical problem of traditional continuous cooking production lines in chemical pulping plants lacking a tailings leveling device, which easily leads to uneven stress on the press rollers and filter screens, damage to the press rollers and filter screens, and uneven moisture content in the pressed tailings.

[0013] 2. By setting an adjustable gate, this utility model can control the discharge height of tailings when it is necessary to adjust the discharge height of the material. The adjustable gate installed on the rear side of the machine casing can be adjusted.

[0014] 3. By setting up a first chain drive structure and a second chain drive structure, this utility model enables a single drive device to drive the material distribution screw shaft and the leveling roller to rotate simultaneously, thus saving the need for a separate drive device.
