Problems solved by technology

[0002] At present, during the brick-making process of brick-making machinery, due to the high extrusion force during use, the reamer sleeve and the mud cylinder bushing in the mixing box of the vacuum extruder will be worn. The increase of the reamer sleeve and the mud cylinder liner will be deformed due to long-term wear and tear, which cannot increase the extrusion line enough and affect the quality of the manufactured bricks
The reamer and mud cylinder liner of the existing vacuum extruder are cast iron materials produced by conventional manufacturing methods. Although they can achieve normal mixing functions, objectively there are problems of fast wear and easy deformation

Embodiment Construction

[0011] Such as figure 1 As shown, 1 represents the mud cylinder bushing, 2 represents the reamer sleeve, and 3 represents the reamer.

[0012] The stirring box of the vacuum extruder is provided with a feed inlet, which is used to add raw materials, and the raw materials are stirred evenly in the stirring box and extruded from the outlet. The inner wall of the mixing box is provided with a mud cylinder liner 1, and the surface of the mud liner 1 is uniformly provided with a high chromium alloy layer. There is a reamer 3 in the inner cavity of the mixing box, and a reamer outer sleeve is fixed on the outside of the reamer 3. 2. The surface of the reamer casing 2 is also provided with a uniform layer of high chromium alloy. The thickness of the high chromium alloy layer on the reamer outer shell 2 and the mud cylinder liner 1 is 2 mm.

[0013] What is described above is only the preferred embodiment of the present invention. For those skilled in the art, without departing from...

Abstract

A stirred tank of a vacuum extruder comprises a reamer and a barrel bush on the inner wall of the stirred tank. A reamer jacket is sleeved on the surface of the reamer. The surfaces of the reamer jacket and the barrel bush are provided with high-chromium alloy layers.

Description

technical field [0001] The invention relates to a stirring box, in particular to a high-strength stirring box of a vacuum extruder. Background technique [0002] At present, during the brick-making process of brick-making machinery, due to the high extrusion force during use, the reamer sleeve and the mud cylinder bushing in the mixing box of the vacuum extruder will be worn. The increase of the reamer sleeve and the mud cylinder liner will be deformed due to long-term wear and tear, and cannot increase the extrusion line enough to affect the quality of the manufactured bricks. The reamer and the mud cylinder liner of the existing vacuum extruder are cast iron materials produced by conventional manufacturing methods. Although they can achieve normal stirring functions, they objectively have the problems of fast wear and easy deformation. Contents of the invention [0003] Aiming at the problems existing in the prior art, the object of the present invention is to provide a...
