TECHNICAL FIELD
[0001] The application relates to the technical field of concrete mixing dust removal, and in particular to an environment-friendly dust removal device for a concrete mixing station. BACKGROUND
[0002] Concrete production refers to mixing cement, sand, gravel (coarse aggregate), water and other necessary additives in a certain proportion, and then performing processes such as stirring, pouring and curing. A concrete mixing station is a facility specially used for producing and stirring concrete. It is usually composed of a concrete mixer, a batching machine, a control system and the like. A mixing station main building produces a large amount of dust in the production process, which easily pollutes the surrounding ecological environment and also has a certain harm to the health of workers.
[0003] At present, most dust removal devices adopt a mode of sucking dust into a water tank to remove the dust by water. This dust removal mode seriously affects the subsequent dust removal effect because the dust is mostly floating on the liquid surface of water, and the effect is poor. Therefore, further improvement can be made. CONTENT OF THE INVENTION

The dust removal filter screen is installed in the dust removal tank and arranged horizontally to separate the dust removal tank into an upper tank chamber and a lower tank chamber. An air inlet pipe is installed at the top of the dust removal tank, one end of the air inlet pipe is communicated with the upper tank chamber, and the other end is used to be communicated with the mixing station main building. An air outlet pipe is installed at the bottom of the dust removal tank and communicated with the lower tank chamber. The dust suction unit is used to suck the dust filtered on the dust removal filter screen and transport the dust to the dust collection unit for compaction and collection.

In this process, the rotation of the suction arm forms a full-surface cleaning mode, which can more fully and completely clean the dust on the dust removal filter screen, so as to ensure the dust cleaning effect.
[0014] Optionally, the driving unit comprises a driving motor, and the driving motor drives the suction arm to rotate through the belt and pulley mode.

[0033] With reference to Figure 2 , in the actual working process, the dust generated by the main building of the mixing plant is input into the upper box chamber 11 of the dust removal box 1 through the air inlet pipe 13 by the fan, flows to the lower box chamber 12 after passing through the dust removal filter screen 2, and is finally discharged through the air outlet pipe 14 to perform dust removal treatment on the dust generated by the main building of the mixing plant. At the same time, the dust filtered on the dust removal filter screen 2 can be sucked by the dust suction unit 3 and transported to the dust collection unit 4 for compaction and collection treatment, so as to prevent the dust from accumulating on the dust removal filter screen 2 and affecting the subsequent dust filtering effect, thereby guaranteeing the dust removal effect.

[0036] Referring to Figure 2 Specifically, in the embodiment, the dust removal unit 3 comprises a dust removal pipeline 31, a suction arm 32 and a dust removal fan 33. Wherein, the dust removal pipeline 31 is fixedly installed in the upper chamber 11, the top end of the dust removal pipeline 31 extends out of the dust removal box 1, and the bottom end of the dust removal pipeline 31 extends and suspends above the dust removal filter screen 2. The suction arm 32 is rotatably installed at the bottom end of the dust removal pipeline 31 and is driven to rotate by a driving unit 34, the top of the suction arm 32 is connected with the dust removal pipeline 31, and the bottom of the suction arm 32 is provided with a suction nozzle 35 along the length direction of the suction arm 32, the suction nozzle 35 is connected with the suction arm 32, and the suction nozzle 35 faces the screen surface of the dust removal filter screen 2.

In this process, the rotation of the suction arm 32 is used to form a full-surface cleaning mode, which can more fully and completely remove the dust on the dust removal filter screen 2, thereby guaranteeing the dust cleaning effect.
[0038] In the embodiment, the driving unit 34 comprises a driving motor, and the driving motor drives the suction arm 32 to rotate through a belt and pulley mode, which will not be described here.
