Description

Technical Field

[0001] The utility model relates to the technical field of processing devices, in particular to a dust treatment device for construction projects. Background Art

[0002] In the field of construction projects, dust treatment has always been an important environmental protection issue. In order to effectively reduce the dust pollution at construction sites, the fog cannon, as an efficient and environmentally friendly dust treatment device, has been widely used.

[0003] In the actual use process, the fog cannon also faces some challenges. Since the output end (i.e., the barrel) of the fog cannon generally tilts upwards during operation to better cover the dust area, however, this design also leads to a problem that after long-term operation, a large amount of water droplets will accumulate at the fog outlet. Under the action of gravity, these water droplets are extremely likely to flow down along the machine shell into the fan. As a key component of the fog cannon, once the internal circuit of the fan comes into contact with water droplets, it may cause faults such as short circuits and insulation damage of the circuit, seriously affecting the normal operation and service life of the fog cannon. Therefore, a dust treatment device for construction projects is needed to solve the above problems. Summary of the Utility Model

[0004] The purpose of the present utility model aims to solve at least one of the above technical defects.

[0005] To this end, an object of the present utility model is to provide a dust treatment device for construction projects to solve the problems mentioned in the background art and overcome the deficiencies existing in the prior art.

[0006] To achieve the above object, an embodiment of one aspect of the present utility model provides a dust treatment device for construction projects, including a fan housing, a fan is fixedly installed inside the fan housing, one end of the fan housing is fixedly connected to a fog pipe through bolts, the end of the fog pipe far from the fan housing is fixedly connected to an annular frame, a flow guide ring is fixedly connected to the inner wall of the annular frame, a plurality of nozzles are fixedly connected to the outer side of the flow guide ring, a water collection frame is fixedly connected to the inner wall of the fog pipe, a support ring is fixedly connected to the end of the fan housing close to the fog pipe, the top surface of the support ring is in contact with the bottom surface of the water collection frame, and a plurality of drain holes are formed through the outer surface of the fog pipe, and the drain holes are communicated with the water collection frame.

[0007] Preferably, a protective net is fixedly connected to the end of the fan housing far from the fog pipe, and the protective net corresponds to the fan.

[0008] Preferably, a sealing ring is fixedly connected to the bottom surface of the water collection frame, a sealing groove is formed on the top surface of the support ring, and the sealing ring is slidably connected to the support ring through the sealing groove.

[0009] Preferably, according to any of the above solutions, a plurality of water troughs are provided on the inner wall of the fog pipe, and the output ends of the water troughs are communicated with the water collecting frame.

[0010] Preferably, according to any of the above solutions, an air outlet cylinder is fixedly connected to the inner wall of the support ring. The air outlet cylinder is located inside the fog pipe and corresponds to the air blower.

[0011] Preferably, according to any of the above solutions, an avoidance groove is formed through the bottom of the annular frame, and a water inlet hose is fixedly connected to the bottom of the diversion ring. The water inlet hose is located inside the avoidance groove.

[0012] Compared with the prior art, the advantages and beneficial effects of the present utility model are as follows:

[0013] When using the fog cannon machine to carry out the treatment operation of construction dust, the blower housing can be installed on the machine table, and the water inlet hose can be connected to the output end of an external water pump. Through the water pump, water can be pumped into the diversion ring through the water inlet hose and sprayed out from the nozzle. Then, the blower is turned on to blow air into the air cylinder. Through the diversion of the air cylinder, the wind speed can be greatly increased. When the flowing air flow sprays out from the fog pipe, it will collide with the sprayed water flow, and the water flow can be broken up into mist, achieving the purpose of removing dust. Moreover, the water droplets accumulated at the output end of the fog pipe will flow to the inner wall of the fog pipe under the action of gravity and flow into the water collecting frame through the water trough. The water collecting frame can collect the refluxed water and will not flow into the blower housing, which can reduce the impact on the blower circuit. In addition, the water accumulated in the water collecting frame will flow out of the fog pipe through the drain hole, which is convenient for the water flow to be discharged.

Detailed implementation manner

[0020] The following further describes the present utility model with reference to the accompanying drawings, but the protection scope of the present utility model is not limited to the following.

[0021] As Figures 1 to 5 shown, a dust treatment device for construction engineering includes a fan housing 1. A fan 2 is fixedly installed inside the fan housing 1. One end of the fan housing 1 is fixedly connected to a mist pipe 3 by bolts. One end of the mist pipe 3 far from the fan housing 1 is fixedly connected to an annular frame 4. A deflector ring 5 is fixedly connected to the inner wall of the annular frame 4. A plurality of nozzles 6 are fixedly connected to the outer side of the deflector ring 5. A water collection frame 7 is fixedly connected to the inner wall of the mist pipe 3. One end of the fan housing 1 close to the mist pipe 3 is fixedly connected to a support ring 8. The top surface of the support ring 8 is in contact with the bottom surface of the water collection frame 7. A plurality of drain holes 9 are formed through the outer surface of the mist pipe 3. The drain holes 9 are communicated with the water collection frame 7.

[0022] As an alternative technical solution of the present utility model, a protective net 10 is fixedly connected to one end of the fan housing 1 far from the mist pipe 3. The protective net 10 corresponds to the fan 2. The setting of the protective net 10 plays a protective role and improves the safety performance of the fog cannon machine.

[0023] As an alternative technical solution of the present utility model, a sealing ring 11 is fixedly connected to the bottom surface of the water collection frame 7. A sealing groove 12 is formed on the top surface of the support ring 8. The sealing ring 11 is slidably connected to the support ring 8 through the sealing groove 12. The setting of the sealing ring 11 can increase the sealing performance between the fan housing 1 and the mist pipe 3 and prevent air flow from flowing out of the connection between the two.

[0024] As an alternative technical solution of the present utility model, a plurality of water tanks 13 are formed on the inner wall of the mist pipe 3. The output end of the water tank 13 is communicated with the water collection frame 7. The setting of the water tank 13 can play a role in guiding the flow, so that the water droplets inside the mist pipe 3 flow into the water collection frame 7.

[0025] As an alternative technical solution of the present utility model, an air outlet pipe 14 is fixedly connected to the inner wall of the support ring 8. The air outlet pipe 14 is located inside the mist pipe 3 and corresponds to the fan 2. When the fan 2 is turned on to blow air towards the air outlet pipe 14, the wind speed can be greatly increased through the diversion of the air outlet pipe 14. When the flowing air flow sprays out from the mist pipe 3, it will collide with the sprayed water flow, and the water flow can be broken into mist.

[0026] A dust treatment device for construction projects has the following working principle:

[0027] 1): When using a fog cannon to carry out the treatment operation of construction dust, the blower housing 1 can be installed on the machine table, and the water inlet hose 16 is connected to the output end of an external water pump. Through the water pump, water can be pumped into the inside of the diversion ring 5 through the water inlet hose 16 and sprayed out from the nozzle 6.

[0028] 2): Turn on the blower 2 to blow air into the air duct 14. Through the diversion of the air duct 14, the wind speed can be greatly increased. When the flowing air current sprays out from the fog pipe 3, it will collide with the sprayed water flow, and the water flow can be broken up into mist, achieving the purpose of removing dust.

[0029] 3): The water droplets accumulated at the output end of the fog pipe 3 will flow to the inner wall of the fog pipe 3 under the action of gravity and flow into the water collection frame 7 through the water tank 13. The water collection frame 7 can collect the recycled water.

[0030] In summary, for this dust treatment device for construction projects, when using a fog cannon to carry out the treatment operation of construction dust, the blower housing 1 can be installed on the machine table, and the water inlet hose 16 is connected to the output end of an external water pump. Through the water pump, water can be pumped into the inside of the diversion ring 5 through the water inlet hose 16 and sprayed out from the nozzle 6. Then turn on the blower 2 to blow air into the air duct 14. Through the diversion of the air duct 14, the wind speed can be greatly increased. When the flowing air current sprays out from the fog pipe 3, it will collide with the sprayed water flow, and the water flow can be broken up into mist, achieving the purpose of removing dust. Moreover, the water droplets accumulated at the output end of the fog pipe 3 will flow to the inner wall of the fog pipe 3 under the action of gravity and flow into the water collection frame 7 through the water tank 13. The water collection frame 7 can collect the recycled water and will not flow into the inside of the blower housing 1, which can reduce the impact on the blower circuit. And the accumulated water inside the water collection frame 7 will flow to the outside of the fog pipe 3 through the drain hole 9, which is convenient for the water flow to be discharged.
