Description
Technical Field
The utility model relates to a ceramic powder processing equipment technical field, especially a screen assembly of broken granulation equipment of pottery pug.
Background
In order to solve the problems of high energy consumption, serious pollution and high production cost caused by drying ceramic slurry by using a spray drying tower, the Chinese patent application with the application number of 2019102196264 discloses a ceramic wet-method low-temperature powder preparation process, and the process sequentially carries out dehydration treatment, low-temperature drying treatment, crushing and granulation treatment on the slurry to obtain dry powder particles with the characteristic of low water content.
The process comprises the steps of firstly, preparing ceramic slurry into a square filter cake with the side length of about 2m and the thickness of about 4cm through a filter press, then, preliminarily dividing the filter cake into small mud blocks with the side length of 5 cm-20 cm, then, cutting the small mud blocks into small mud materials with the grain diameter of less than 3cm, then, drying the small mud materials by using the waste heat of a kiln, and finally, crushing and granulating the dried small mud materials to form powder particles with the grain diameter meeting the requirements, thereby solving the problem of high energy consumption caused by the adoption of a spray drying tower in the traditional process.
In the technical scheme provided by the invention, the small pug is crushed and granulated by adopting ceramic pug crushing and granulating equipment. The principle is as follows:
the dried mud falls into a crushing bin of the equipment from a feed inlet above the equipment; the dried mud is broken into large particles falling into the circular arc-shaped screen mesh by the breaking hammers rotating at high speed in the breaking bin, the large particles are driven to circularly shed above the circular arc-shaped screen mesh by the continuous circumferential rotation of the plurality of breaking hammers and the large particles sinking on the circular arc-shaped screen mesh, and the large particles are gradually broken into small particles with small particle sizes by collision; in addition, when the breaking hammer rotates to the position above the circular arc-shaped screen, small particles with small particle sizes on the circular arc-shaped screen are extruded into a friction gap between the breaking hammer and the circular arc-shaped screen by the rotating extrusion of the breaking hammer, the small particles extruded into the friction gap rub through holes in the circular arc-shaped screen, so that the small particles are rubbed to form powder particles with ultra-small particle sizes, and finally the powder particles meeting the particle size requirements penetrate through the through holes in the circular arc-shaped screen through the crushing and friction granulation, fall onto a discharge belt and are transported out.
In production, in order to ensure the crushing efficiency, the friction gap between the circular arc-shaped screen and the crushing hammer is not too large, and only needs to be slightly larger than the particle size of the required powder particles. The friction gap is generally 1 to 1.5mm, so that the requirement on the shape of the installed circular arc screen is very high. The existing structure is that a plurality of strip-shaped semi-circular arc-shaped ribs with the same size are uniformly arranged in a crushing bin along the axial direction of a rotating shaft, and then a stainless steel wire net with the wire diameter of about 0.2mm is fixed on the mounting ribs to form an arc-shaped screen.
However, this structure has the following problems:
1. because the mounting ribs are in a semicircular arc shape, and one end of each mounting rib is in an open state, the mounting ribs are easy to deform under stress in the mounting process, so that the screen is deformed after mounting, the requirement on coaxiality cannot be met, the screen is easy to interfere with a breaking hammer, and the structure is time-consuming and labor-consuming in mounting and low in precision;
2. the steel wire in the stainless steel net is easy to displace in the friction process in the use process, so that the aperture is enlarged, the steel wire is easy to break, the service life is short, and the circular arc-shaped screen is required to be frequently replaced.
Therefore, it is necessary to improve the structure.
SUMMERY OF THE UTILITY MODEL
