Description

Technical Field

[0001] The utility model relates to the technical field of concrete production, in particular to an aggregate dust removal device for concrete production. Background Art

[0002] At present, concrete aggregate refers to the granular loose materials that play a role of skeleton or filling in concrete. It is divided into coarse aggregate and fine aggregate. Coarse aggregate refers to pebbles, crushed stones, etc., and fine aggregate refers to natural sand, artificial sand, etc. Aggregates with a particle size greater than 4.75mm are called coarse aggregates, commonly known as stones. Commonly used are crushed stones and pebbles. Crushed stones are rock particles with a particle size greater than 4.75mm made by natural rocks or rocks through mechanical crushing and screening. Pebbles are rock particles with a particle size greater than 4.75mm formed by natural weathering, water flow transportation, sorting, and accumulation. Therefore, a large amount of dust will be generated when the aggregate is unloaded, which will affect the surrounding environment and operators.

[0003] Existing aggregate dust removal devices for concrete production mostly use the method of spraying aggregates to remove dust. However, after the dust is scattered and sprayed, the water adsorbs the dust and adheres to the inner wall of the mixing tank. The area near the nozzle cannot be rinsed due to the limited spraying range, making subsequent cleaning more troublesome. Utility Model Content

[0004] In order to solve the technical problem that after the dust is sprayed, the water absorbs the dust and adheres to the inner wall of the mixing tank, and the area near the nozzle cannot be rinsed due to the limitation of the spraying range, making subsequent cleaning more troublesome, the utility model provides an aggregate dust removal device for concrete production.

[0005] The utility model is implemented by the following technical scheme: an aggregate dust removal device for concrete production, comprising a tank body, a feed port is arranged on the top of the tank body, a dust removal mechanism is arranged at the bottom of the feed port, and is used to prevent aggregate dust from being raised during concrete production; a discharge pipe corresponding to the dust removal mechanism is arranged inside the tank body, a spiral discharge rod is rotatably installed inside the discharge pipe, and a cleaning mechanism is arranged on the top of the tank body, and is used to scrape off dust on the inner wall of the tank body near the spray mechanism.

[0006] As a further improvement of the above scheme, the cleaning mechanism includes a motor fixedly mounted on the outside of the tank body, the output end of the motor is transmission-connected to the first transmission assembly, the first transmission assembly is transmission-connected to the second transmission assembly, the top of the second transmission assembly is transmission-connected to a rotating shaft, the top of the rotating shaft is fixedly connected to a connecting rod, and one end of the connecting rod is fixedly connected to a scraper corresponding to the inner wall of the tank body.

[0007] As a further improvement of the above solution, the spray mechanism includes a spray box fixedly mounted on the top inner wall of the tank body, the top of the spray box is connected to a water inlet pipe, and the bottom of the spray box is connected to a spray head.

[0008] Through the above technical solution, when feeding aggregate, the spraying method is adopted to reduce dust, and at the same time the aggregate is washed to remove soil, thereby improving the quality of concrete during production.

[0009] As a further improvement of the above solution, a first baffle and a second baffle are arranged inside the tank body, the first baffle and the second baffle are both arranged obliquely, and the second baffle is located below the first baffle.

[0010] Through the above technical solution, the dust is completely dispersed by blocking the first baffle and the second baffle, thereby improving the flushing effect.

[0011] Through the above technical solution, during the aggregate dust removal and cleaning process, the dust on the inner wall of the tank near the nozzle can be scraped off, eliminating the trouble of subsequent processing and reducing labor intensity.

[0012] As a further improvement of the above scheme, the first transmission assembly includes a belt and a pulley, the second transmission assembly includes a transmission shaft and a bevel gear set transmission-connected to the pulley, the rotating shaft is transmission-connected to the bevel gear set, and the rotating shaft passes through the first baffle.

[0013] As a further improvement of the above solution, one end of the spiral discharge rod is connected to the output end of the motor, a screen is provided at the bottom of the discharge pipe, and a sewage pump is provided on one side of the tank body.

[0014] Through the above technical solution, the sewage from aggregate washing falls from the screen, is discharged through the sewage pump, and can be connected to the filtering device to save the use of water resources.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The utility model feeds concrete aggregate into the material inlet, and opens a nozzle to spray the aggregate to remove dust on the surface of the aggregate, and finally the aggregate falls into a discharge pipe, and a motor drives a spiral discharge rod to rotate, so that the cleaned aggregate is transported to a concrete mixing box for production. When the motor rotates, the first transmission component and the second transmission component drive the rotating shaft to rotate, so that the rotating shaft drives the scraper to rotate through the connecting rod, so as to scrape the inner wall of the tank that cannot be washed by the nozzle. In the process of aggregate dust removal and cleaning, the design cleans the inner wall of the processing equipment at the same time, avoids the trouble of subsequent cleaning, and reduces labor intensity.
