Description

Technical Field

[0001] The utility model belongs to the technical field of bulk dry-mixed mortar, in particular to a bulk dry-mixed mortar dust collecting device. Background Art

[0002] Dry-mixed mortar, also known as premixed mortar, is a new type of material that is made by mixing sand, cement, fly ash, additives and other materials in a certain proportion according to certain strength requirements in advance. Compared with mortar mixed on site, it has many advantages.

[0003] When loading dry-mixed mortar, a bulk loader is needed. Since a lot of dust is generated during the bulk loading process, the bulk loader needs to be equipped with a dust removal device during use. A common method is to set a retractable pipe near the bulk loader's discharge port that can rise and fall with the bulk loader's discharge port, and at the same time, use fans and other equipment to create negative pressure in the pipe, thereby sucking away the dust generated during the loading process and reducing the amount of dust. Since most of the retractable pipes currently used for dust removal are corrugated pipes, during the dust removal process, some of the dust will adhere to the inner wall when passing through the inside. Since no negative pressure is generated inside the bulk loader when it is not in use, the dust attached to the inner wall will fall directly from the bottom opening, thereby polluting the environment and affecting the health of the staff.

The bottom end of the dust conveying pipe 6 passes into the bellows 5, and a plurality of connecting frames 10 are arranged in an array on the outer side of the bottom end of the dust conveying pipe 6. The outer ends of the multiple connecting frames 10 are commonly connected to a cleaning ring 11, and a brush 12 is arranged on the outer side of the cleaning ring 11. The brush 12 is used to brush off the dust on the inner wall of the bellows 5. A dust conveying auger 13 is also installed on the inner side of the dust conveying pipe 6, and the bottom end of the dust conveying auger 13 passes through the bottom end of the dust conveying pipe 6. During the rotation of the dust conveying auger 13, the dust can be transported.

[0024] Among them, the dust collecting hopper 8 is in the shape of an inverted truncated cone, so that the inner wall of the dust collecting hopper 8 is inclined. After the dust conveying auger 13 enters the interior thereof, the dust in the dust collecting hopper 8 will slide toward the dust conveying auger 13, and the size of the top opening is larger than the size of the bottom opening of the bellows 5, so that the dust scraped off the inner wall of the bellows 5 can fall in easily.

[0030] Specific working principle:

[0031] Before using the utility model, firstly, the top of the discharge port 14 in the utility model is connected with the discharge port of the dry-mixed mortar storage bin, and the external power supply and control panel of the utility model are connected, and the operation of the utility model is controlled by the external control panel. During the use of the utility model, first, the vehicle transporting the dry-mixed mortar is moved under the dust collecting hood 4, and then the hoist 16 in the utility model is started. After the wire rope is released by the hoist 16 to make the dust collecting hood 4 fall to a position close to the cargo compartment of the vehicle, the storage bin is controlled to discharge. During the discharge process, the fan 21 in the utility model is started at the same time, and a negative pressure is formed in the bellows 5 through the fan 21, so that the dust generated during the discharge of the dry-mixed mortar is sucked into the dust collecting box 19 through the bellows 5, the dust collecting branch pipe 3, and the dust collecting main pipe 2. After entering the dust collecting box 19, the dust is intercepted by the filter 22 The dust collecting hood 4 is stopped, thereby collecting the dust. After the loading is completed, the discharge of the storage bin is stopped. After that, the fan 21 is kept running, and the winch 16 is controlled to raise the dust collecting hood 4. During the rising process of the dust collecting hood 4, the bellows 5 contracts. During the contraction process, the inner wall of the bellows 5 is scraped against the brush 12 located on the outer side of the bottom end of the dust conveying pipe 6. The dust attached to the inner wall of the bellows 5 is brushed down by the brush 12 and falls into the dust collecting hopper 8 until the bottom end of the dust conveying auger 13 enters the dust collecting hopper 8. After that, the motor 24 of the utility model is started, and the dust conveying auger 13 is driven to rotate by the motor 24, so that the dust falling into the dust collecting hopper 8 is transported to the ash conveying inclined pipe 9 located at the top of the dust conveying pipe 6, until it enters the dust collecting box 19 under the action of gravity potential energy and the wind force of the fan 21, and then the operation of the utility model is stopped.
