Description

Technical Field

[0001] The utility model relates to the technical field of green production, in particular to an environmentally friendly commercial concrete aggregate silo dust reduction device. Background Art

[0002] Commercial concrete aggregate refers to a main raw material used in concrete preparation, usually a mixture of gravel, sand, cement and other ingredients. Commercial concrete aggregate plays a supporting and filling role in concrete, which can increase the strength and durability of concrete. Commercial concrete aggregate will generate dust when stored, which needs to be treated for dust reduction;

[0003] For example, the Chinese utility model patent with publication number CN219906204U discloses a dust suppression device for aggregate silo, which includes a support frame, a fixing mechanism and a cleaning mechanism. The support frame is arranged on the partition wall of the silo through the fixing mechanism, and the support frame is arranged along the length direction of the partition wall of the silo. The cleaning mechanism includes a water tank, a water pump, a water pipe, a spray plate and a plurality of spray heads. The spray plate is arranged on the support frame, and a cavity is formed inside the spray plate. The spray head is connected and arranged on the spray plate. One end of the water pipe is connected to the cavity, and the other end is arranged in the water tank through the water pump. The water pump is used to pump water in the water tank into the cavity.

[0004] There are some problems with the above-mentioned device. When in use, the device can support the spray plate by setting up a support frame on the outer wall of the silo, and the support frame can support the spray plate. By adjusting the water pump, the water pump can draw the dust reduction water in the water tank into the cavity. Under the action of the nozzle, the nozzle can carry out dust reduction treatment in the silo, which can reduce the dust overflow into the air and provide a certain protection for the processing personnel. However, during the modification, since the dust reduction components are arranged on the top of the silo body, it is impossible to carry out all-round dust reduction inside the silo. At the same time, it is necessary to continuously supply water to the dust reduction device, which easily leads to overflow of water resources and waste.

[0005] Therefore, we propose an environmentally friendly commercial concrete aggregate silo dust reduction device to solve the above-mentioned problems. Utility Model Content

[0009] As a preferred technical solution of the utility model, the side of the second water tank is connected to a water supply pipe; the water supply pipe connects the second water tank and the atomizing nozzle.

[0010] As a preferred technical solution of the utility model, the end surface of the commutator close to the first water tank is directly fixedly connected to the screw rod.

[0011] As a preferred technical solution of the utility model, a movable block is arranged on the screw rod; the movable block is matched with the screw rod; an atomizing nozzle is arranged below the movable block; and the atomizing nozzle is connected to the water supply pipeline.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The device is provided with a first water tank and a second water tank. When the device is in use, the first water tank is connected to an external water source to store water and the water is transported to the second water tank through a water supply pipe. The U-shaped tube at the bottom of the second water tank ensures the water level balance between the two second water tanks. At the same time, the water level between the first water tank and the second water tank also needs to be balanced. Under the principle of communicating vessels, the first water tank continuously supplies water to the inside of the second water tank. At the same time, the water level monitor inside the first water tank monitors the water level information inside the first water tank in real time. When the water level reaches the set highest point, the external water source is stopped from transporting the excess water to the inside of the first water tank, thereby ensuring that the water source inside the second water tank is always in a sufficient state during use to prevent the occurrence of water shortage. At the same time, when not in use, the water level monitor inside the first water tank controls the switch of the first throttle valve to stop the external water source from supplying water to the inside, thereby ensuring that the water source in the device will not be wasted due to overflow due to overfilling;

[0016] 2. The device is provided with a dual-axis motor and a commutator. Through the connection between the motor shafts and the commutator at both ends of the dual-axis motor, each motor shaft drives the two movable shafts to rotate. The rotation of the movable shaft drives the steering gear above to rotate synchronously, and then the steering gear drives the lead screw to rotate, and then the movable block moves synchronously on the lead screw, so that the atomizing nozzle moves back and forth at the top of the bin body, so that the device can perform dust reduction processing without dead angles when performing atomization and dust reduction on the bin body, thereby improving the dust reduction performance of the device.
