[0023] Example 1

[0024] See also Figure 1-Figure 3The utility model provides a dust removal device for concrete production, comprising a bracket 1 and a dust suction mechanism 2, the dust suction mechanism 2 is mounted on the bracket 1, the dust suction mechanism 2 is used to collect smoke and dust generated when the mixing tank is stirred, the dust suction mechanism 2 comprises a dust suction nozzle 4 and an exhaust fan 5, the dust suction nozzle 4 is connected to the air inlet end of the exhaust fan 5 through a connecting pipe, the dust suction nozzle 4 is fixedly mounted on the bracket 1, and the air outlet end of the exhaust fan 5 is connected to a dust washing mechanism 6;

[0025] The dust cleaning mechanism 6 is used to perform dust removal operation on the air sucked in by the exhaust fan 5 .

[0026] It should be noted that, see Figure 1 The dust suction nozzle 4 is located above the mixing tank, and can immediately remove the generated dust when the mixing tank is working.

[0027] By adopting the above scheme, through the use of the dust collection mechanism 2, during the production of concrete, the dust generated by the mixing tank during the mixing is operated by the exhaust fan 5, so that the dust collection nozzle 4 generates suction, and the raised dust is sucked into the dust washing mechanism 6 for treatment, which can effectively reduce the discharge of dust into the external environment and reduce the harm to the environment.

[0028] In this embodiment, the dust washing mechanism 6 includes a first water tank 7 and a filter 8. The first water tank 7 is connected to the air outlet end of the exhaust fan 5 through an air guide pipe 9. The air outlet end of the air guide pipe 9 runs through the side wall of the first water tank 7. The filter 8 is installed on the air outlet pipe of the first water tank 7. A dust suppression member 10 is installed on the top of the first water tank 7. The dust suppression member 10 is used to perform dust suppression operations on the dust in the first water tank 7.

[0029] The filter element 8 includes a filter screen 14 and a frame 15, wherein the filter screen 14 is fixedly connected to the frame 15, and the frame 15 is detachably mounted on the end of the air outlet pipe of the first water tank 7;

[0030] The inner wall of the frame 15 is provided with an internal thread, and the air outlet pipe of the first water tank 7 is provided with an external thread matching the internal thread;

[0031] The mesh number of the filter screen 14 is set to 460-650 meshes.

[0032] It should be noted that when the air outlet end of the air guide pipe 9 is exhausting, the exhausted air blows onto the water surface in the first water tank 7;

[0033] On the one hand, it can make the dust carried by the exhaust gas adhere to the water surface, thus filtering the dust;

[0034] On the other hand, the air can be blown on the water surface to make the water surface fluctuate, thus preventing the dust absorption effect from being reduced when too much dust is attached to the water surface;

[0035] The external thread and the internal thread are used in combination to facilitate the frame 15 to be removed from the air outlet pipe of the first water tank 7 for cleaning.

[0036] By adopting the above scheme, through the use of the dust washing mechanism 6, when the dust is introduced into the first water tank 7 through the air duct 9, the air introduced by the air duct 9 contacts the water surface in the first water tank 7, and the dust carried in the air adheres to the water surface, and the air blows the water surface to generate ripples, so that the dust adhered to the water surface is wetted and sinks into the water, ensuring that the water surface can continue to adhere to the dust, which can effectively reduce the dust discharged into the external environment;

[0037] By using the filter element 8, when the air in the first water tank 7 is discharged, it is filtered by the filter screen 14, which can effectively reduce the discharge of dust.

[0038] In this embodiment, the dust suppression component 10 includes a water pump 11 and an atomizing nozzle 12. The water outlet of the water pump 11 is connected to the water inlet of the atomizing nozzle 12 through a drain pipe. The water pump 11 is used to provide a water source to the atomizing nozzle 12. The atomizing nozzle 12 is fixedly installed on the inner top of the first water tank 7. The water inlet of the water pump 11 is connected to a second water tank 13.

[0039] By adopting the above scheme, through the use of the atomizing nozzle 12 and the water pump 11, when the air containing dust enters the first water tank 7, the water mist sprayed by the atomizing nozzle 12 contacts the air entering the first water tank 7, and the water mist adheres to the dust and falls into the first water tank 7, so as to clean the air discharged into the external environment, effectively reduce the dust entering the external environment, and reduce the pollution to the environment.

[0040] Working principle: During concrete production, the dust generated during the mixing tank mixing is operated by the exhaust fan 5, so that the dust nozzle 4 generates suction and the raised dust is sucked into the first water tank 7. When the dust enters the first water tank 7, the air introduced by the air duct 9 contacts the water surface in the first water tank 7, and the dust carried in the air adheres to the water surface, and the air blows the water surface to generate ripples, so that the dust adhered to the water surface is wetted and sinks into the water. At the same time, the water mist sprayed by the atomizing nozzle 12 contacts the air entering the first water tank 7, and the dust adhered to the water mist falls into the first water tank 7, which can clean the air discharged into the external environment, effectively reduce the dust entering the external environment, and reduce the pollution to the environment.

[0041] It should be noted that the model specifications of the exhaust fan 5 and the water pump 11 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail.

[0042] The power supply and principle of the exhaust fan 5 and the water pump 11 are clear to those skilled in the art and will not be described in detail here.

[0043] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
