Description

Technical Field

[0001] The invention relates to the technical field of concrete mixing, and in particular to a water circulation dust removal device for a concrete mixing plant. Background Art

[0002] Concrete is abbreviated as concrete: it is a general term for engineering composite materials that are cemented into a whole by cementitious materials. The term concrete usually refers to cement as a cementitious material, sand and stone as aggregates; mixed with water (which may contain admixtures and additives) in a certain proportion, and then mixed to obtain cement concrete, also known as ordinary concrete, which is widely used in civil engineering.

[0003] During the coagulation production and mixing process, a large amount of dust will be generated. If the dust is not treated, it will not only pollute the factory environment, but also easily affect the health of the workers. Most of the existing dust removal devices spray a large amount of water into the air, so that the water mist absorbs the dust in the air to remove the dust. However, some of the existing dust removal devices are only responsible for spraying water mist and are unable to recycle the waste water, thereby resulting in a large waste of water resources and easily making the factory floor wet. Not only does it pose a safety hazard, but the sewage mixed with dust will move with the workers and pollute the environment of the entire factory. Therefore, the present application provides a water circulation dust removal device for a concrete mixing plant to meet the needs. Summary of the invention

[0013] Compared with the prior art, the present invention has at least the following beneficial effects: 1. Start the first water pump to send the clean water in the water tank to the spray head through the water outlet pipe and perform dust removal. Then start the rotating motor at the bottom of the mounting plate to drive the rotating plate to rotate through the driving shaft. Since the driving block is eccentrically arranged at the bottom of the rotating plate and the driving shaft is inside the empty slot, the driving shaft will drive the inner end of the mounting rod to reciprocate. The inner end of the mounting rod drives the outer end of the mounting rod to move in the opposite direction synchronously through the first rotating shaft, thereby driving the spray head to reciprocate through the outer end of the mounting rod. This design enables the spray head to perform dust removal over a larger range.

[0014] 2. By providing a recovery component, during the dust suppression operation, the connecting rod moves synchronously with the inner end of the connecting rod. Since the bottom of the connecting rod is fixedly connected to both sides of the inner end of the water receiving bucket, the inner end of the water receiving bucket moves synchronously with the inner end of the connecting rod, so that the water receiving bucket is always directly below the spray head. At this time, the sewage sprayed by the spray head after dust suppression will be caught by the water receiving bucket and flow into the sewage tank. Before falling into the sewage tank, the sewage passes through the first filter plate and the second filter plate inside the drawer to filter the solid impurities in the sewage. At the same time, the linear motor can be used to drive the slider to move on the surface of the slide rod, so that the slider drives the moving plate to move, and the bottom plate and the cleaning brush at the bottom of the moving plate are moved to clean the surface of the first filter screen to prevent impurities in the sewage from clogging the filter screen. At this time, starting the second water pump can pump the clean water on the top layer of the sewage into the water storage tank through the water inlet pipe. This design can recycle the sewage generated by dust suppression and reuse it after sedimentation, effectively reducing the waste of resources.

[0015] 3. When the device is performing dust removal work, the ground will inevitably be damp. At this time, the hot air blower is started to generate hot air. The hot air dries the ground through the hot air outlet pipe and the hot air outlet to make the ground dry without affecting the movement of people. The exhaust fan is started to generate suction inside the condensation box through the suction pipe, so that negative pressure is generated in the condensation box. The hot air containing water vapor generated by drying is sucked into the condensation box by the exhaust pipe and the exhaust port. The hot and humid air contacts the condenser, and the temperature drops rapidly to reach the dew point. The humid air begins to condense. As the air flows forward, water vapor is continuously precipitated through condensation. The precipitated water is collected through the water collection port and filtered through the third filter screen, and finally pumped out through the third water pump, and returned to the water storage tank through the reflux pipe for collection, thereby performing water circulation, reducing the waste of water resources, and ensuring the dryness of the ground of the concrete mixing plant.
