Problems solved by technology

The traditional ceramic filter is extruded in an extruder, and then punctured by a needle to form a hole. This device that forms first and then forms a hole brings a problem, that is, when the hole is pierced, the overall shape will be deformed due to the pressure. Deformation, seriously affecting the yield

Embodiment 1

[0014] like figure 1 The shown extruding device for preparing ceramic filters includes a propulsion rod 2 driven by a mechanical arm 1. The end of the propulsion rod 2 is fixed with a cylindrical extruding head 3, and the bottom of the extruding head 3 is provided with a center at the center A cylindrical barrel 4 on the same straight line, the barrel 4 is provided with a cavity that can accommodate the displacement of the extrusion head 2; the bottom end of the barrel 4 is connected with a discharge cylinder 5, and the bottom end of the discharge cylinder 5 is A discharge mold 6 is connected; the bottom end of the cylinder body 4 has the same diameter as the top end of the discharge cylinder 5, and the bottom end of the cylinder body 4 and the top end of the discharge cylinder 5 are connected and fixed by a flange ring; the 6 ends of the discharge mold There are several metal needle-like structures on the top.

Embodiment 2

[0016] Referring to Example 1, the cylindrical barrel 1 is hoisted by the bracket 7, and there is a distance from the ground or the operating table, which is convenient for the operator to pick up the material at the discharge mold.

Embodiment 3

[0018] Referring to Example 1, the outer circumference of the extrusion head 2 is equal to the inner circumference of the barrel 1 .

Abstract

The invention discloses a squeezing device for preparing a ceramic filter. The squeezing device comprises a propelling rod driven by a mechanical arm, a cylindrical squeezing head is fixedly arrangedat the end of the propelling rod, a cylindrical barrel with the circle center on a same straight line with that of the squeezing head is arranged at the bottom of the squeezing head, a cavity allowingthe squeezing head to move inside is formed in the barrel, the bottom end of the barrel is connected with a discharging barrel, and the bottom end of the discharging barrel is connected with a discharging die. The squeezing device is scientific and reasonable in structural design and capable of meeting continuous production needs, and molding and hole forming are performed at the same time, so that the problem that conventional industry is too low in yield is avoided.

Description

technical field [0001] The invention belongs to the field of refractory materials, and in particular relates to an extruding device for preparing ceramic filter sheets. Background technique [0002] Ceramic filter is widely used in metallurgy and foundry industry to filter molten metal. It adopts mullite (cordierite) ceramic material, high-quality and high-density straight hole mesh, so that the product has high resistance to thermal shock and high-temperature casting Temperature characteristics, straight hole design ensures the balance between flow and strength, effectively removes impurities and slag particles, etc., greatly improving the mechanical properties, surface quality and product qualification rate of castings. The ceramic filter is mainly used to filter out the inclusions in the casting, reduce the gas in the casting, reduce the degree of turbulence during the filling of the metal liquid flow, reduce the surface defects of the casting, and significantly reduce th...
