Description

Concrete Mixing Station Silo Wet Dust Recovery System

technical field

The utility model relates to the field of concrete mixing, in particular to a wet dust recovery system for a silo of a concrete mixing station.

Background technique

Concrete mixing plant is a joint device used to concentrate mixing concrete. It has a high degree of mechanization and automation. With the development of municipal construction, it has great advantages to adopt centralized mixing and provide commercial concrete mixing stations, so it has developed rapidly. In order to promote concrete pumping construction, it can realize mixing, conveying, Create conditions for joint operation of pouring machinery.

Concrete mixing plant is mainly composed of 5 major systems including mixing host, material weighing system, material conveying system, material storage system and control system and other auxiliary facilities. Among them, the exhaust port on the top of the silo of the material storage system, the powder is discharged into the atmosphere and pollutes the environment. Especially in the surrounding areas of the city, the production of the powder ash that is seriously polluted will be banned.

Utility model content

The technical problem to be solved by the utility model is to provide a wet dust recovery system for the silo of a concrete mixing station for dust recovery.

The utility model solves the technical problem of the wet dust recovery system of the silo of the concrete mixing station, including a water tank, a discharge main pipe and an outlet pipe. The mixing end extends into the water tank; one end of the outlet pipe is installed in the water tank, and the other end is the connection end of the mixing main engine.

Further, a water pump is also included, and the water pump is installed on the outlet pipe.

Further, the outlet metering scale is also included, and the outlet metering scale is installed on the outlet pipe and located behind the water pump.

Further, it also includes a stirrer installed in the water tank.

Further, at least two branch pipes are included, all branch pipes are connected to the discharge main pipe, and outlets of all branch pipes are distributed in the water tank.

The beneficial effects of the utility model are: the recovery system uses the discharge main pipe to introduce the dust discharged from the top of the silo into the water tank, so that the dust is mixed with the water in the water tank, thereby avoiding the discharge of dust and greatly reducing pollution; The mixture of dust and water in the mixer can be introduced into the mixing machine, so that the dust can be recycled and good economic benefits can be obtained. The agitator installed in the water tank stirs the mixed liquid of powder and ash in the water tank, and then sends it to the mixing main machine through the water pump for repeated use. This not only completely eliminates air pollution, but also reuses the water and water ash in the water tank, which has a significant impact. social and economic benefits.

Parts, parts and numbers in the figure: water tank 1, discharge main pipe 2, outlet pipe 3, water pump 4, agitator 5.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1, the utility model includes a water tank 1, a discharge main pipe 2 and an outlet pipe 3. The two ends of the discharge main pipe 2 are respectively a mixing end and a powder bin outlet connection end, and the mixing end extends into the water tank 1 Inside: one end of the outlet pipe 3 is installed in the water tank 1, and the other end is the connection end of the stirring host. When in use, the recovery system is installed under the material storage system, as shown in Figure 2, the powder hopper outlet connection end of the discharge main pipe 2 is connected to the powder hopper outlet, and an appropriate amount of water is stored in the water tank 1, The mixing end of the discharge header 2 extends into the water. Install one end of the outlet pipe 3 in the water tank 1, preferably at the bottom of the water tank 1, and then connect the connection end of the outlet pipe 3 to the mixer to provide water for the mixer at any time.

During the use of the concrete mixing plant, the dust discharged from the powder silo of the material storage system enters the water tank 1 through the discharge main pipe 2, thereby mixing with the water in the water tank 1, and the mixed liquid enters the water tank through the outlet pipe 3 In the mixing machine, water is provided for the mixing machine, and the discharged dust also enters the mixing machine with the mixed liquid, which makes the dust recovered, which not only solves the problem of dust pollution, but also recovers the dust, which can be said to kill two birds with one stone.

In order to facilitate the transportation of the dust mixture, as shown in FIG. 1 , a water pump 4 is also included, and the water pump 4 is installed on the outlet pipe 3 . The water pump 4 is beneficial to convey the mixed liquid, and is convenient to provide water for the stirring host.

In order to realize quantitative water supply, as shown in FIG. 1 , an outlet metering scale is also included, and the outlet metering scale is installed on the outlet pipe 3 and behind the water pump 4 . The export metering scale can be used to control the water delivery to meet the requirements of the mixing host.

In order to better mix the dust and water, as shown in FIG. 1 , an agitator 5 is also included, and the agitator 5 is installed in the water tank 1 .

In order to make the dust and water contact better, it also includes at least two branch pipes, all branch pipes are connected with the discharge main pipe 2 , and the outlets of all branch pipes are distributed in the water tank 1 . The branch pipe can increase the contact area between dust and water, so as to obtain a good mixing effect.

After installing this recovery system, a dust recovery system will be added to the concrete mixing plant, and the five major systems will become six major systems. A steel pipe and a water tank dust collection device are used to connect the material storage system and the mixing main engine to form a closed system. Through a closed wet one-way receiving and emptying powder system, the powder ash is absorbed by water, so that the powder is not emptied, reducing air pollution, and the water in the system and the water ash mixed with water can be reused. The product has low investment and obvious implementation effect, which is conducive to popularization.
