The utility model relates to the technical field of concrete production, by arranging a block with a certain inclination angle in the feed part, and arranging a fan and a U-shaped cavity containing water at the block to further absorb the dust raised when the concrete is poured.

[0004] The utility model dust-free concrete production device removes dust by vacuuming, but the dust from the concrete will remain on the fan and will also be blocked in the pipe. After a long time, it is easy to cause fan damage and pipe blockage, which seriously affects the dust collection efficiency and cannot meet the use requirements. Therefore, a dust-free concrete production device is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-3 A dust-free concrete production device includes a hopper 2 installed inside a machine body 1, a dust suppression device extending to the inside of the hopper 2 is installed on the side wall of the machine body 1, and a blowing structure used in conjunction with the dust suppression device is installed on the top of the hopper 2; the dust suppression device includes a water tank 3 and a booster pump 4 fixedly installed on the side wall of the machine body 1, a nozzle 5 arranged outside the top of the hopper 2, and a nozzle 6 fixedly connected to the outside of the nozzle 5 and extending to the inside of the hopper 2. The nozzle 6 can be an atomizing nozzle.

[0024] In this embodiment, water pipes 7 are installed at both the output end and the output end of the booster pump 4, and the two water pipes 7 are fixedly connected to the water tank 3 and the nozzle 5 at one end. A clamp 8 for fixing the nozzle 5 is installed on the outer wall of the hopper 2 by bolts, and the number of the clamps 8 is four.

[0025] It should be noted that there are multiple nozzles 6, and the multiple nozzles 6 and the four clamps 8 are arranged equidistantly in a ring shape, and a water level observation window is installed on the front of the water tank 3 to facilitate observation of the water level in the water tank 3. The back of the water tank 3 is fixedly connected with a water inlet pipe and a water outlet pipe, and the ends of the water inlet pipe and the water outlet pipe are threadedly connected with sealing covers.

[0026] The blowing structure includes a gantry 18 mounted on the top of the hopper 2 by bolts and a fan 19 fixedly mounted on the lower surface of the gantry 18. By starting the fan 19, the dust is controlled in the hopper 2, and at this time, water adheres to the dust to make the dust particles fall, effectively preventing respiratory infections of workers caused by dust splashing.

[0027] In this embodiment, the hopper 2 is provided with a feed channel 9, a flow dividing chamber 10 and a discharge channel 11 which are interconnected. The flow dividing chamber 10 is provided with a flow limiting mechanism for limiting the flow of concrete.

[0028] The flow limiting mechanism includes a turntable 12 arranged inside the diversion chamber 10, six partition plates 13 equidistantly installed on the outer surface of the turntable 12, a rotating shaft 14 installed inside the hopper 2 through a bearing and fixed to the turntable 12, and a driving structure arranged outside the hopper 2 for driving the turntable 12.

[0029] The driving structure includes an intermittent motor 15 fixedly mounted on the outer wall of the hopper 2, a transmission gear 16 fixedly mounted on the output shaft of the intermittent motor 15, and a driven gear 17 fixedly mounted on the other end of the rotating shaft 14 and meshing with the transmission gear 16. The size of the six material separators 13 is adapted to the interior of the diverter chamber 10, and a certain gap is left between the material separators 13 and the inner wall of the diverter chamber 10. A rubber scraper can be installed on one side of the material separator 13 close to the inner wall of the diverter chamber 10 to scrape off the concrete material remaining on the inner wall of the diverter chamber 10.

[0030] When this embodiment is in use, the intermittent motor 15 is started, and the turntable 12 is rotated through the transmission cooperation between the transmission gear 16 and the driven gear 17, and the partition plate 13 drives the material to flip. Since the space between the two partition plates 13 is always consistent, the amount of material in the diversion chamber 10 each time remains consistent, thereby achieving quantitative discharging.

[0031] The working principle of the above embodiment is:

[0032] When in use, concrete is introduced into the hopper 2, and the booster pump 4 is started to transport the water in the water tank 3 to the nozzle 5, and the water is sprayed out through the nozzle 6 to achieve the effect of atomization. Then, by starting the fan 19, the dust is controlled in the hopper 2. At this time, the water adheres to the dust and the dust particles fall, which effectively prevents the respiratory tract infection of the staff caused by the dust splashing.

[0033] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.
