Description

Environment-friendly totally enclosed building material production facility

Technical Field

The invention relates to the technical field of building construction, in particular to environment-friendly fully-closed building material production equipment.

Background

In terms of raw material use, current mortar production equipment can only use dry sand for blanking. Because the discharge hole of the existing mortar production equipment is conical, the blanking area is small, the pressure born by the blanking hole is large, and the blanking hole is easy to be blocked by the blanking of the wet sand, so that the blanking of the wet sand cannot be performed. The ready-mixed mortar is prepared by mixing cement, sand, fly ash and an additive according to a certain proportion, stirring, and then conveying the ready-mixed mortar into a mortar stirring tank at a construction site for use. If any water content of the used raw materials exceeds the standard in the process, the mortar is solidified in a short time and cannot be normally discharged, so that the raw materials cannot contain water before stirring. Therefore, the wet sand is required to be dried in the production process, so that not only is the manpower and material resources wasted, but also the construction cost is increased, and the fuel is used in the drying process, so that the environmental pollution is very easy to cause.

In terms of the production mode of the ready-mixed mortar, domestic production of the ready-mixed mortar mainly depends on plant mixing, and the plant mixing occupies too large area and the transportation and production processes are complicated. Firstly, secondary pulling and transportation exist during the plant-mixed transportation of the ready-mixed mortar, and the generated tail gas emission of the vehicle is extremely easy to cause air pollution. In the early production stage, a large amount of fuel is needed in the drying process of the raw materials, and the existence of the link not only reduces the utilization rate of resources, but also increases the discharge amount of waste. Thirdly, most of the existing building material transport vehicles adopt hydraulic dump trucks, the problem of inaccurate coverage exists in the transport process of the vehicles, the material throwing phenomenon easily occurs along the way, and the raise of dust pollution index is easily caused. And at present, the phenomenon that materials are directly transported to a construction site by a transport vehicle to be stirred exists, so that manpower and material resources are wasted, and pollution to the environment is caused.

In terms of environmental benefits of mortar production equipment, the existing mortar production equipment cannot realize secondary utilization of urban building waste due to the limitation of tank shapes and feed openings. The factors such as various kinds and non-uniform water content during recycling of the construction waste materials, and the like, lead to the fact that the screened raw material ready mixed mortar production factory cannot be directly used. Along with the continuous development of cities, hidden danger of building rubbish pollution is seen, resource utilization of building rubbish in China needs to be improved, and therefore stirring equipment capable of realizing secondary utilization of the building rubbish is designed and used in a trend.

2. The unloading speed is high, 1.2 tons per minute, the unloading time is shortened, and the transportation efficiency is improved; the residual rate is extremely low, namely two parts per million, is close to zero, and saves materials.

3. In order to meet the domestic requirements on the quality management standard of the dry-mixed mortar technology, the lifting type material transportation tank truck is provided with a special sampling device, and the quality of mortar raw materials is guaranteed to be monitored and detected in real time.

4. The hydraulic lifting tank is adopted, and the inclination angle is 45 degrees.

5. The lower half part of the tank body is adhered with a silica gel plate, so that friction resistance is reduced, and wet sand can smoothly slide to the outlet.

6. The tail part of the tank body is changed, so that the wet sand can slide to the lowest position of the tank bottom.

7. The T-shaped discharge hole is additionally formed in the lowest position of the tail part of the tank, so that the discharge is ensured to be satisfied.

By combining the above expressions, the lifting type material transporting tank car meets the transporting condition of wet sand entering the tank.
