Method for producing concrete building block and special equipment thereof

Abstract

A method for producing the building blocks with concrete includes such steps as conveying the raw materials to stirrer communicated with shaping machine, stirring to obtain concrete clinker, and direct shaping by shaping machine. Its advantages are no layering and long service life of mould.

Description

technical field [0001] The invention relates to a production method and equipment of a wall block, in particular to a production method of a concrete block and special equipment thereof. Background technique [0002] The production method of existing a kind of concrete block is generally to adopt raw materials such as cement, sand, gypsum, crushed stone, coal cinder, blowing agent, filler to produce, and the role played by various raw materials after mixing is different, and crushed stone, coal cinder Such large particles play the role of supporting the aggregate in the concrete block, sand and other fillers play the role of filling, the foaming agent plays the role of reducing the weight of the unit block, and the cement plays the role of bonding and curing. All kinds of raw materials must be fully mixed and evenly , in order to play its due role, but because the volume, weight and specific gravity of various raw materials are different, how to achieve and maintain the idea...

AI Technical Summary

Problems solved by technology

In industrial production, after various raw materials are added to the mixing equipment, they are usually mixed and pre-mixed when they are in a dry state, and then water is added to make concrete clinker, in order to achieve an ideal mixing state. It should be solid materials of various particle sizes. The state of uniform mixing with liquid should be maintained until the concrete clinker arrives in the processing mold and is processed. Keeping has different effects. In small-scale production, manual feeding is generally used. Concrete clinker can be processed near the main machine, and manually added to the main machine quickly. There is only one pouring process, which basically has little effect on the maintenance of its mixing state. , but because of its low production efficiency, it cannot be applied to the requirements of large-scale industrial production

Large and medium-sized production units generally use belt transportation to transport concrete clinker from the mixing equipment to the main machine for forming. During this process, there are at least two discharges from the mixer hopper to the belt and from the belt to the main machine hopper. The method has the following disadvantages: in the process of pouring, the concrete clinker needs to be greatly deformed. When pouring, the volume, weight and specific gravity of various raw materials are different, and the falling speed is also different. The original concrete clinker The uniform mixing state is seriously affected, resulting in the phenomenon that the concrete clinker that finally reaches the mold will inevitably have the phenomenon of peeling off, delamination and fragmentation of raw materials with different specific gravity, which is quite different from the uniform mixing state in the mixing equipment.

At the same time, because the horizontal gap between the hopper and the corresponding caliber of the distribution box of the main machine is too large, when the concrete clinker falls into the mold from the distribution box, the distribution around the mold will be dissatisfied, and the produced blocks will not be compacted and have insufficient strength. And other quality problems, even if it is forced to meet the requirements, it will increase power consumption and seriously shorten the service life of the main engine and molds. Usually, it needs to be replaced after producing 50,000 to 60,000 pieces. The equipment failure rate is high, frequent shutdowns, and low production efficiency.

At the same time, because the concrete clinker is easily bonded to the belt, the loss of raw materials is high, and the belt is easy to age and damage
