Description

Technical Field

[0001] The utility model relates to the technical field of cement production, in particular to a waterproof mineral powder stable external admixture device. Background Art

[0002] The main raw materials of mineral powder, slag and fly ash, are solid wastes. After being ground, they are added to cement to improve the later strength of cement and achieve the purpose of reducing the clinker consumption ratio. In the prior art, the materials are usually transported to the disc weighing scale by connecting a double-screw conveying pressure reamer. The mineral powder weighing scale and the air conveying chute are conveying equipment. The mineral powder is directly transported into the cement mill hopper through the air conveying chute, thereby completing the metering and adding of the mineral powder.

[0003] Patent announcement number CN213084736U discloses an air conveying chute including a chute body, a feeding port and a discharging port are arranged on the chute body, a conveying fan is arranged on the higher side of the chute body, an output pipe connected to the chute body is arranged on the conveying fan, an air inlet pipe is arranged on the conveying fan, and a drying unit and a filtering unit are arranged on the air inlet pipe. By arranging the drying unit and the filtering unit on the air inlet pipe, the air entering the conveying fan can be dried and filtered, so that the dried air can be passed into the chute body, so as to prevent the powder in the chute body from being damp and hardened, and improve the conveying quality of the material.

[0004] Although the prior art CN213084736U has many benefits during use, it still has the following problems: although it heats the humid air, the moisture in the air still exists, which will increase the humidity in the air, and water droplets during rain can also easily enter the air inlet pipe, causing the material to become damp. Utility Model Content

[0005] The utility model aims to provide a device for stabilizing external addition of waterproof mineral powder to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a waterproof mineral powder stabilization external admixture device, comprising a shell, a fixed block, a connecting block and a fixed plate, a ventilation pipe is plugged and installed on one side of the outer wall of the upper end of the shell, and corrugated plates equidistantly and parallelly distributed are installed on the inner wall of the shell, and fixed blocks are installed on both sides of the outer wall of the lower end of the shell, a screw body is arranged inside the fixed block, a connecting block is arranged on the outer wall of one side of the screw body, and support blocks equidistant and parallelly distributed are installed on the upper outer wall of the connecting block, and a fixed plate is installed on the upper outer wall of the support block.

[0007] When using a waterproof mineral powder stable external admixture device in the technical solution, the fan body drives the air flow, so that the gas passes through the inside of the ventilation pipe between the corrugated plates until it is discharged through the fan body. The moisture in the gas collides with the outer wall of the corrugated plate and gathers, thereby achieving the purpose of reducing the moisture in the air. The motor body drives the screw body to rotate, driving the connecting block, the supporting block, the fixed plate and the scraper to move horizontally. The scraper can push and move the water droplets and foreign matter on the outer wall of the corrugated plate to separate the water droplets and foreign matter.

[0008] Preferably, the ventilation pipe is connected to the inside of the housing, and a fan body is arranged on the outer wall of one end of the ventilation pipe. The fan body drives the airflow to flow, so that the outside air enters the ventilation pipe through the housing.

[0009] Preferably, the screw body passes through the outer wall of one end of the fixing block and is provided with a motor body, the motor body is connected to the outer wall of the fixing block, and the motor body drives the screw body to work.

[0010] Preferably, the size of the fixing plate is smaller than the spacing between the corrugated plates, and the fixing plate is located between the corrugated plates.

[0011] Preferably, scrapers are fixed to the outer walls on both sides of the fixed plate, and the scrapers are in contact with the outer wall of the corrugated plate. The scrapers scrape and clean the outer wall of the corrugated plate.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the utility model achieves the effect of reducing air humidity by arranging a screw body, a scraper and a corrugated plate; the fan body drives the air to flow, so that the gas passes through the inside of the ventilation pipe between the corrugated plates until it is discharged through the fan body; the moisture in the gas collides with the outer wall of the corrugated plate and gathers thereby achieving the purpose of reducing the moisture in the air and preventing the material from getting damp; and the motor body drives the screw body to rotate, driving the connecting block, the supporting block, the fixing plate and the scraper to move horizontally; the scraper can push and move the water droplets and foreign matter on the outer wall of the corrugated plate, so that the water droplets and foreign matter are separated and the cleanliness of the outer wall of the corrugated plate is ensured.
