Problems solved by technology

The receiving box of the lower unit uses a continuous auger to push the mud forward, and the auger only has a screw propulsion function and does not have an exhaust function, so it cannot further discharge the gas in the mud
The above factors lead to the fact that the vacuum degree of the mud material cannot meet the production requirements of bricks and blocks in the plateau area. It is very difficult to form the mud material, and the product cracks and blooms, which cannot be produced normally.
[0003] In addition, the mold seat with a continuous and gradual compression structure at the extruder mouth cannot fully release the internal stress generated by the mud during the compression process. When the mud comes out of the extruder mouth, it is easy to cause product cracking

Embodiment 1

[0030] Such as Figure 1-5 As shown, the plateau brick machine of the present invention includes a superior unit and a lower unit, and the superior unit includes a mixing box 5, a blanking box 8 and a driving device 1, and the blanking box 8 is connected to the outlet end of the mixing box 5, and the dropping box A vacuum chamber is set in the material box 8, a feed inlet 2 is set at the rear of the stirring box 5, and a stirring propulsion assembly is arranged in the stirring box 5, and the stirring propulsion assembly includes the stirring shaft 5 and the stirring knife 4, the spiral twisting shaft installed on the stirring shaft 5 in turn. Knife 6, mixing knife 4 and stirring shaft 3 form a stirring part to stir the mud, and the spiral reamer 6 and stirring shaft 3 form a propulsion part to push the mud forward, and the stirring shaft 3 is connected to the driving device 1. A sieve plate 7 is installed at the discharge port of the stirring box 5, and several sieve holes 15 ...

Embodiment 2

[0036] Such as Figure 6 As shown, the mold base 11.3 is sequentially provided with the first compression cavity 11.2, the first expansion cavity 11.4, and the extrusion cavity 11.5 along the axial discharge direction. The first expansion cavity 11.4 is a gourd cavity or a waist drum cavity, and the extrusion cavity 11.5 The diameter gradually decreases along the axial discharge direction, and the rest are the same as in Example 1.

Embodiment 3

[0038] Such as Figure 7 As shown, the mold base 11.3 is sequentially provided with a first compression chamber 11.2, a first expansion chamber 11.4, a second compression chamber 11.7, a second expansion chamber 11.8, and an extrusion chamber 11.5 along the axial discharge direction. The diameters of the first compression chamber 11.2 and the second compression chamber 11.7 gradually decrease along the axial discharge direction, the first expansion chamber 11.4 and the second expansion chamber 11.8 are cylindrical cavities with equal diameters, and the extrusion chamber 11.5 is a cylinder with equal diameters cavity.

Abstract

The invention relates to a brick machine, in particular to a plateau brick machine applied to plateau sections. The plateau brick machine comprises an upper-level unit and a lower-level unit, wherein the upper-level unit comprises a stirring box, the front portion of the stirring box is connected with a feeding box, the feeding box is connected with a material collecting box in the lower-level unit, the front end of the material collecting box is connected with an extruder opening, a stirring thrust assembly is disposed in the stirring box, a discharging opening of the stirring box is provided with a sieve plate, a plurality of sieve holes are formed in the sieve plate, an extrusion shaft is arranged in the material collecting box, a paddle is arranged on the front portion of the extrusion shaft, and a spiral vane is disposed on the rear portion of the extrusion shaft. By means of the arrangement of the sieve plate and the paddle, pug is high in fragmentation degree in the upper-level stirring and crushing stage, is high in vacuum degree after being vacuumized and is stirred and crushed again in the lower-level extrusion process, so that gas in the pug overflows and is exhausted completely, the vacuum degree of the pug can meet production requirements of products in the plateau sections, and product quality and the yield are improved.

Description

technical field [0001] The invention relates to a brick machine, in particular to a plateau brick machine used in plateau areas. Background technique [0002] In the brick and tile industry, the double-stage vacuum brick machine is the most commonly used brick-making equipment, which is mainly composed of an upper-level unit and a lower-level unit. Vacuum degree is a key parameter in the production process of the double-stage vacuum brick machine. For the plateau area with an altitude of more than 1000m, due to the thin air, the pressure difference between the inside and outside of the brick machine is small, so the forming performance and vacuum degree of the brick machine are greatly affected. The requirements are high. The upper unit of the existing two-stage vacuum brick machine mostly installs a crushing trowel at the outlet of the mixing box, and cuts the mud by rotating the trowel. However, in actual production, due to manufacturing and life factors Due to the consi...
