Hydraulic direct pushing type refining mud machine and method thereof

Abstract

A hydraulic direct pushing type refining mud machine comprises a rack and is characterized in that a vertical refining mud machine cylinder body is fixed to the rack, a mud inlet is formed in the upper end of the vertical refining mud machine cylinder body, and a mud outlet is formed in the lower end of the vertical refining mud machine cylinder body; a first hydraulic piston is arranged above the vertical refining mud machine cylinder body, a second hydraulic piston is arranged below the vertical refining mud machine cylinder body, the first hydraulic piston and the second hydraulic piston reciprocate through an oil pump, the outline of the first hydraulic piston is matched with the inner wall of the vertical refining mud machine cylinder body, the outline of the second hydraulic piston is larger than the outline of the mud outlet, an exhaust hole is formed in the side wall of the upper portion of the vertical refining mud machine cylinder body, and the exhaust hole is connected with a vacuum pump; and the hydraulic direct pushing type refining mud machine has the beneficial effects that the friction force is small, the defects of mud heating and too high water evaporation speed are overcome, layering peeling of the interior and the exterior of the mud cannot happen, various kinds of mud can be produced, mud compaction is uniform, the volume of an inner chamber is small, and the applicability of the refining mud machine is g realty improved.

Description

technical field [0001] The invention relates to the technical field of mud refining equipment, in particular to a hydraulic direct-push mud refining machine and a method thereof. Background technique [0002] Ceramic manufacturing generally has main processes such as mud making, mud refining, molding, drying, and roasting. The performance of the mud directly affects the molding and subsequent product performance. The mud with good performance will produce products with fewer internal defects and better physical and chemical properties. Stable, high mechanical strength and other advantages. [0003] In order to improve the compactness, plasticity and other properties of the mud, in addition to improving the mud formula, mud moisture content and process environment, the refining of the mud is also very important. In most wet-formed ceramic production fields, especially the production of honeycomb ceramics, practicing The mud process is an indispensable process link. A good mu...

Problems solved by technology

The mud refining machine of this structure has the advantages such as mature technology and good continuity; but the mud refining machine of the above-mentioned structure still has the following disadvantages: (1) the mud material is pushed forward with the rotation of the stirring blade (spiral blade), and the mud refining machine The material will be twisted and squeezed multiple times during the advancing process, and shearing will generate friction, which will easily heat up the mud. Once the mud heats up, the water will evaporate faster, making the mud dry. The resistance will increase, the heat will be more serious, and a vicious circle; (2) The shear torque and friction force exerted by the spiral blades on the mud in the equipment are relatively different from the inside and outside, and the stress applied to the mud is very uneven. The cross-sectional direction of the mud section is prone to the phenomenon that the middle protrusion is similar to the thread shape. In severe cases, the inner and outer layers of the mud material will be peeled off and the purpose of dense and uniform mud material will not be achieved, which will bring difficulties to subsequent production; (3) for poor fluidity , the mud with relatively high viscosity and hardness will have defects such as mud heating, insufficient extrusion power, and uneven compactness of the mud; (4) For soft and slippery mud, it cannot be squeezed because the mud is too soft The thrust provided by the screw or the helical blade is transmitted to the mud material in front of it, and the thrust itself cannot be transmitted to the longitudinal direction, so it has to overflow laterally to the periphery, and the mud material will stick to the screw rod, the helical blade, and the wall of the inner chamber of the mud refining machine. In this situation, it is equivalent to the fact that the mud material makes a circular motion on the same circular plane in the mud refining machine or sticks to a certain point in the inner bore and cannot achieve the purpose of mud refining; (5) The traditional mud refining machine has a relatively large span and the inner The chamber volume is large, and a large amount of mud is required to be filled when it is used without load. Once the mud drill fails or is replaced with other mud, it is necessary to disassemble the mud drill equipment to remove the residual mud in the inner chamber, because The bore volume is large, the equipment is complex, and there are supporting equipment such as trowels, mud tanks, sieve plates, screws, spiral blades, etc., the workload of disassembly and cleaning is huge, which seriously affects production efficiency
