Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of production equipment, relates to the field of concrete production, especially relates to a spraying dust-settling device for concrete preparation. BACKGROUND

[0002] Concrete is a kind of composite material prepared by mixing cement, water, sand (fine aggregate), stone (coarse aggregate) and, if necessary, admixture and mineral admixture in a certain proportion, and then stirring, molding and curing.

[0003] The cement, sand (fine aggregate) and stone (coarse aggregate) used for preparing concrete are respectively stacked, and when preparing concrete, a forklift is usually used to shovel the raw materials such as sand and stone and shovel them into a receiving pit for mixing.

[0004] The commonly used fog gun machine atomizes water flow through an atomizing nozzle, uses air flow to blow the mist droplets outward, adsorbs dust particles in the air, and carries the dust particles to settle, thereby achieving the purpose of dust settling. SUMMARY

[0005] The utility model discloses a spraying dust-settling device for concrete preparation, which can solve the technical problem of dust scattering caused by dust settling of the fog gun machine and improve dust settling efficiency and effect.

[0006] The utility model discloses a spraying dust-settling device for concrete preparation, which can solve the technical problem of dust scattering caused by dust settling of the fog gun machine and improve dust settling efficiency and effect.

[0007] When shoveling raw materials, the suction fan and water pump are activated. The suction fan draws the dust raised during the shoveling process towards the wall panel, thus suppressing the dust dispersion. The water pump draws water from the lower chamber of the water tank to the outlet pipe, where it flows out through the long outlet, forming a water curtain on the front of the wall panel. This absorbs the dust on the front of the wall panel and collects it into the upper chamber of the water tank. The filter baffle in the water tank filters the mixture of water and dust, allowing the water to be reused and improving resource utilization. At the same time, the water pump sends water from the lower chamber to the manifold pipe, and the atomizing nozzles on the spray pipe spray water mist onto the top of the raw material pile, thereby capturing the floating dust. After settling, the dust is drawn into the water curtain by the suction fan, improving dust suppression efficiency and effect.

[0008] To further optimize this technical solution, the wall panel is tightened and fixed to the rear wall of the water tank with studs, and the left and right sides and the top side of the wall panel are fixedly connected to the enclosure. The front of the enclosure protrudes from the front of the wall panel, and the two ends of the water outlet pipe protrude from the sides of the enclosure respectively. The manifold is assembled to the top surface of the enclosure with the help of connectors.

[0009] The enclosure can reduce water splashing when it flows out of the long outlet and reduce dust scattering when it is blown to the front of the wall panel, thus ensuring the water flow's dust capture effect.

[0010] To further optimize this technical solution, the connector includes a connecting strip that is fixedly installed on the top surface of the enclosure. A slot is provided at the top of the connecting strip, and a manifold is inserted into the slot. The two ends of the manifold protrude from the two ends of the connecting strip, respectively.

[0011] The slots on the connecting strip facilitate the installation and removal of the manifold, increasing its flexibility of use.

[0012] To further optimize this technical solution, the suction fan includes a power structure and fan blades; the power structure is fixedly installed on the back of the wall panel, the output shaft of the power structure passes through the wall panel and is rotatably installed in a sealed manner with the wall panel, and the output shaft of the power structure is assembled with the fan blades.

[0013] The power structure of the suction fan is installed on the back of the wall panel to avoid direct contact with dust, reduce dust damage to the power structure, and extend the service life of the power structure.

[0014] To further optimize this technical solution, the suction fan also includes a protective ring disposed around the fan blades and a support ring rotatably sleeved on the output shaft; a first arm is evenly disposed circumferentially on the outer ring wall of the protective ring, and the first arm is fixedly connected to the wall plate; and a second arm is evenly disposed circumferentially on the inner ring wall of the protective ring, and the second arm is fixedly connected to the support ring.

[0015] The first arm, fixed to the wall panel, supports the protective ring around the fan blades, thus protecting them. The second arm on the inner wall of the protective ring coaxially supports the support ring within the protective ring and supports the output shaft of the suction fan, thereby ensuring the coaxiality of the output shaft and guaranteeing operational reliability.

[0016] To further optimize this technical solution, the external cover of the power structure is equipped with a protective cover, which is sealed and fixedly installed with the wall panel.

[0017] The protective cover enhances the protection of the power structure and ensures operational safety.

[0018] To further optimize this technical solution, the filter baffle includes an outer frame that is inserted into the water tank, the outer frame is filled with filter media, and filter screens are fixedly connected to the top and bottom surfaces of the outer frame.

[0019] The outer frame is inserted into the water tank to support the filter screen and filter media, and to filter the water flow. It has a simple structure and is flexible and reliable in use.

[0020] To further optimize this technical solution, a limiting strip is provided on the inner side wall of the water tank, and the bottom surface of the outer frame abuts against the limiting strip.

[0021] The limiting strip inside the water tank positions and supports the outer frame, making it flexible and reliable to use.

[0022] To further optimize this technical solution, water pumps are installed at both the left and right ends of the outer side of the water tank, and the water pumps are respectively connected to both ends of the outlet pipe and both ends of the manifold through pipelines.

[0023] Water pumps are installed on both sides of the water tank and connected to the two ends of the outlet pipe and the manifold pipe through pipelines, thereby improving the pumping efficiency and dust reduction efficiency.

[0024] The beneficial effects of this utility model are as follows:

[0025] 1. The water pump draws water from the water tank to the water outlet pipe on the front of the wall panel, and the water is discharged from the long outlet on the water outlet pipe, thus forming a water curtain on the front of the wall panel. The suction fan draws the dust raised during the material removal process into the water curtain to absorb the dust, suppress the dust dispersion, and ensure the dust reduction effect.

[0026] 2. The water pump synchronously pumps the water from the water tank into the manifold and then into the spray pipe. After being atomized by the atomizing nozzle, the water is sprayed out. The upward tilt of the spray pipe and its protrusion from the front of the wall panel increase the spray area, which captures the upward-floating dust. The dust is then carried into the airflow area driven by the suction fan and sucked into the water curtain, thereby collecting the dust.

[0027] 3. After the water curtain carries the dust back into the water tank, the filter baffle in the water tank filters and screens the water flow. The purified water flows into the lower chamber and is pumped by the water pump for recycling, which improves energy saving. The dust left in the upper chamber can be easily cleaned by removing the filter baffle, making it flexible to use.

[0028] 4. The power structure of the exhaust fan is installed on the back of the wall panel and protected by a protective cover to prevent dust from damaging the power structure and extend its service life. The far end of the output shaft driven by the power structure is supported by a support ring to ensure coaxiality and operational reliability. Attached Figure Description

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0037] Please see the appendix Figures 1-3A dust suppression spraying device for concrete preparation includes an open water tank 1. The water tank 1 is divided into an upper cavity 101 and a lower cavity 102 by a filter partition 2. A wall panel 4 is fixedly installed on the top of the rear wall of the water tank 1. The wall panel 4 is tightened and fixed to the rear wall surface inside the water tank 1 by studs. A suction fan 7 is mounted on the front of the wall panel 4. A gap is provided between the suction fan 7 and the wall panel 4 to ensure the airflow of the suction fan 7 during operation. After the water tank 1 is placed next to the raw material pile, the suction fan 7 sucks up the dust raised during the raw material shoveling process.

[0038] Please see the appendix Figure 2 Appendix Figure 4 The suction fan 7 includes a power structure 701 and fan blades 702. The power structure 701 is fixedly installed on the back of the wall panel 4. The power structure 701 can be a conventional servo motor. The output shaft of the power structure 701 passes through the front of the wall panel 4. The output shaft can be rotatably installed on the wall panel 4 with the help of matching bearings and shaft seals, ensuring the sealing of the assembly between the output shaft and the wall panel 4. The fan blades 702 are fixedly installed with the output shaft. In addition, to ensure the stability of the output shaft rotation, the suction fan 7 also includes a protective ring 703 disposed around the fan blades 702. The outer ring wall of the protective ring 703 is evenly provided with first support arms 705 along the circumferential direction. The first support arms 705 are all fixedly connected to the wall panel 4, thereby supporting the protective ring 703. The inner ring wall of the protective ring 703 is evenly provided with first support arms 705 along the circumferential direction. A second support arm 706 is uniformly provided, and each second support arm 706 is fixedly connected to a support ring 704. The support ring 704 is rotatably sleeved with the output shaft of the power structure 701. Thus, the protective ring 703 and the support ring 704 support the output shaft, ensuring the stability of the output shaft and the rotation of the fan blade 702. The protective ring 703 also protects the fan blade 702, enhancing the safety of the fan blade 702 in use. After the fan blade 702 is driven to rotate, it sucks up the dust and blows the dust to the front of the wall panel 4. The wall panel 4 intercepts the dust, thereby preventing the dust from damaging the power structure 701. The power structure 701 is covered with a protective cover 707, which is sealed and fixedly installed with the wall panel 4 to further enhance the safety of the power structure 701.

[0039] Please see the appendix Figure 1 Appendix Figure 5When the dust blown by the suction fan 7 reaches the front of the wall panel 4, a water outlet pipe 5 is installed at the top of the front of the wall panel 4. The water outlet pipe 5 is connected to the water pump 3 on the water tank 1 via a pipeline. The water pump 3 is connected to the lower cavity 102 on the water tank 1. The water pump 3 draws water from the water tank 1 into the water outlet pipe 5. The water pump 3 can be a dry water pump 3. In order to improve the pumping efficiency, water pumps 3 can be installed on both sides of the water tank 1 and connected to both ends of the water outlet pipe 5 via pipelines, so that water flows into the water outlet pipe 5. A long water outlet 501 is opened on the side wall of the water outlet pipe 5. After the water flows out from the long water outlet 501, a water curtain is formed on the front of the wall panel 4. The water curtain captures the dust drawn by the suction fan 7 and falls into the upper cavity 101 of the water tank 1 to achieve the dust reduction effect.

[0040] Please see the appendix Figure 1 Appendix Figure 2 Appendix Figure 4 The wall panel 4 is fixedly connected to three sides of the left and right sides and the top side of the wall panel 4. The front of the wall panel 401 protrudes from the front of the wall panel 4. The wall panel 401 can reduce the splashing of water when it flows out of the long water outlet 501 and reduce the dust from being blown to the front of the wall panel 4 and the dust from being scattered outward, thus ensuring the dust capture effect of the water flow and the water recycling effect.

[0041] Please see the appendix Figure 1 Appendix Figure 6 While the water outlet 5 forms a water curtain to absorb dust through the elongated water outlet 501, the top surface of the wall panel 4 is equipped with a manifold 6. The manifold 6 can be assembled to the top surface of the enclosure 401 with the aid of connectors. The connectors include a connecting strip 8 that is fixedly installed to the top surface of the enclosure 401. The top end of the connecting strip 8 has a slot 801, and the manifold 6 is inserted into the slot 801. Both ends of the manifold 6 protrude from the ends of the connecting strip 8, which facilitates connection with the water pump 3 through a pipeline, so that water can also be injected into the manifold 6. Spray pipes 601 are evenly arranged on the manifold 6 and are inclined upwards. The spray pipe 601 is connected to the manifold 6 and protrudes from the front of the wall panel 4. Atomizing nozzles 602 are evenly connected to the spray pipe 601. Water is pumped into the spray pipe 601 through the manifold 6 and sprayed outward from the atomizing nozzles 602 on the spray pipe 601. Due to the outward extension of the spray pipe 601, the atomizing nozzles 602 capture the dust floating upward from the raw material pile after spraying the water mist, increasing the dust capture area. During the process of the water mist carrying the dust to settle, it is carried and sucked onto the wall panel 4 by the airflow blown by the suction fan 7, which facilitates the collection and treatment of dust and the recycling and reuse of water mist.

[0042] Please see the appendix Figures 1-3After the water and dust mixture falls into the upper cavity 101 of the water tank 1, the filter baffle 2 filters the mixture of water and dust. The filtered water flows into the lower cavity 102 for water recycling. The filter baffle 2 includes an outer frame 201 inserted into the water tank 1. The top and bottom surfaces of the outer frame 201 are fixedly connected to filter screens 202. The outer frame 201 is filled with filter media, such as sponge or glass fiber, to perform multi-stage filtration of the water and ensure the filtration effect. The inner side wall of the water tank 1 is provided with a limiting strip 103, which abuts against the bottom surface of the outer frame 201 to support the outer frame 201.

[0043] The working principle of the dust suppression spraying device for concrete preparation is as follows: A water tank 1 is placed beside the raw material pile, and water is poured into the tank. When shoveling raw materials, a water pump 3 and a suction fan 7 are activated. The suction fan 7 drives airflow over the raw material pile, thereby drawing the dust upwards onto the wall panel 4. Simultaneously, the water pump 3 pumps the water from the tank 1 to the outlet pipe 5 on the front of the wall panel 4, and discharges it through the elongated outlet 501, thus forming a water curtain on the front of the wall panel 4 to absorb the dust blown onto it. The water pump 3 also simultaneously pumps the water from the tank 1 to the manifold 6 and then to the spray pipe 601, where it is atomized by the atomizing nozzle 602 and sprayed out. The upward tilt and protrusion of the spray pipe 601 onto the front of the wall panel 4 increase the spray area, thereby capturing the upward-blown dust and causing it to settle. During the settling process, the water mist that absorbs dust falls into the airflow area driven by the suction fan 7 and is carried by the airflow to the front of the wall panel 4, thereby collecting the dust. The water curtain on the front of the wall panel 4 and the sprayed water mist simultaneously absorb the raised dust, improving dust reduction efficiency and effect; the water flow and water mist that absorb dust fall back into the water tank 1. The water flowing back into the water tank 1 is filtered and purified by the filter baffle 2 before flowing into the lower cavity 102 of the water tank 1, where it is absorbed again by the water pump 3, realizing the recycling of water resources and improving energy-saving effect.
