Description

Technical Field

[0001] The present invention relates to the technical field of concrete production, and more particularly to a UHPC ultra-high performance concrete production line. Background Art

[0002] Ultra-high performance concrete, abbreviated as UHPC, also known as reactive powder concrete, is the most innovative cement-based engineering material in the past three decades, achieving a major leap in the performance of engineering materials. The design theory of ultra-high performance concrete is the maximum packing density theory. The particles of different particle sizes in its constituent materials are packed most densely in the optimal proportion, that is, the gaps between the stacked millimeter-level particles are filled with micron-level particles, and the gaps between the stacked micron-level particles are filled with submicron-level particles. Steel fibers are doped inside to increase the high mechanical properties, ultra-high durability, wear resistance and thermal insulation properties of ultra-high performance concrete.

[0003] The ultra-high performance concrete production line mainly consists of a steel fiber vibrating feeder, a cement feeder, a microbead feeder conveyor, a silica fume feeder conveyor and a mixing feeder. It is mainly used for batch production of UHPC ultra-high performance concrete to improve production efficiency.

[0004] The existing ultra-high performance concrete production line still has the following problems: During use, steel fibers are added to the ultra-high performance concrete to reduce the brittleness of the concrete. At that time, the steel fibers will cross and agglomerate, and a steel fiber vibrating feeder is needed to shake and feed the steel fibers. However, the shaking feeding efficiency of the existing steel fiber vibrating feeder is poor. In addition, since a shaking screen is used for screening during shaking, the shaking screen has to bear a large weight when there are too many steel fibers, which greatly affects the shaking amplitude and may cause damage to the shaking screen.

[0005] Secondly, most existing ultra-high performance concrete production lines add steel fiber, cement, water, microspheres or silica fume into a mixing device in sequence, which requires a lot of waiting time during mixing, which greatly affects the efficiency of ultra-high performance concrete production.

[0006] During the transportation of raw materials, the conveyor belt needs to transport multiple materials into the mixing barrel for mixing. At this time, multiple materials will stick to the conveyor belt. The adhesion of these materials will first cause the conveyor belt to fall during repeated transportation, resulting in a poor working environment. Secondly, excessive adhesion of materials will also cause plate formation.

[0007] In addition, during the mixing process of concrete, the concrete may stick to the inner wall of the mixing barrel and form a lump, which is troublesome to clean. In addition, some concrete may not be fully mixed, affecting the quality of ultra-high performance concrete.

[0008] In view of this, we propose a UHPC ultra-high performance concrete production line. Summary of the Invention

[0023] 3. Beneficial effects

[0024] Compared with the prior art, the advantages of the present invention are that: when the steel fibers are discharged, the steel fibers can be placed inside the feed barrel and the shaking motor can be used to drive the metal screen plate and the screen to perform double vibration, so that the steel fibers first pass through the metal screen plate for preliminary load-bearing and shaking, and then gradually pass through the screen to be shaken and fall into the discharge hopper, providing a certain buffer for the screen, thereby preventing a large amount of steel fibers from entering the screen at the same time and shaking to increase the load on the screen, affect the shaking frequency and cause damage to the screen. When the steel fibers fall into the screen, the shaking motor 1 and the shaking motor 2 can be used to vibrate simultaneously to improve the discharge efficiency and at the same time transport the steel fibers through the discharge hopper into the pre-mixing barrel;

[0025] When steel fiber, micro beads and silica fume enter the pre-mixing barrel at the same time, the rotating motor can be used to drive the rotating mixing frame to rotate slowly. During the rotation process, the rotating stirring rod can be used to evenly mix the steel fiber, micro beads and silica fume. When the mixture is rotated to more than 90 degrees, it will be transported from the feed curve plate to the conveyor belt by gravity, and then transported to the mixing barrel for mixing, which effectively reduces the mixing time and improves the production efficiency of concrete.

[0026] When the conveyor belt is conveying, the hopper can be used to guide the material into the mixing barrel. During the guidance, the rubber scraper will scrape off the material adhering to the surface of the conveyor belt because the conveyor belt is in a moving state, and the cleaning block will be used to clean the conveyor belt to avoid material loss or waste or the conveyor belt from becoming brittle.

[0027] During the mixing process, the mixing motor can be used to drive the mixing main rod to fully mix the concrete. During the mixing, the mixing scraper will clean the inner wall of the mixing barrel to prevent the concrete from sticking to the inner wall of the mixing barrel and forming a plate.

[0064] Working principle: First, when feeding steel fibers, the steel fibers can be placed inside the feed barrel 110 and the shaking motor 130 and the shaking machine can be used to drive the metal screen plate 120 and the screen 164 to perform double vibrations, so that the steel fibers first pass through the metal screen plate 120 for preliminary load-bearing and shaking, and then gradually pass through the screen 164 for shaking and fall into the discharge hopper 163, providing a certain buffer for the screen 164 to avoid a large number of steel fibers from entering the screen 164 at the same time and shaking, which increases the load of the screen 164 and affects the shaking frequency and causes damage to the screen.
