Description

Technical Field

[0001] This utility model relates to the field of mechanical breakers, and more specifically to a mechanical breaker for aqueduct demolition. Background Technology

[0002] In traditional aqueduct demolition operations, mechanical breakers are widely used to break concrete structures. However, existing mechanical breakers generate a large amount of dust during operation, which not only affects the safety of the construction environment but also poses a potential threat to the health of workers. The spread of dust reduces the air quality at the construction site, and prolonged exposure to dust may lead to health problems such as respiratory diseases and lung infections.

[0003] Currently, most hydraulic breaker operating environments lack effective dust collection and control devices. While dust suppression can be achieved by installing atomizing nozzles on the outside of the construction site, the dust generated during the crushing process still tends to disperse throughout the site. As a result, the dust cannot be effectively cleaned up and absorbed in a timely manner, leading to dust permeating the air and workers being exposed to harmful environments for extended periods, thus increasing safety hazards. Utility Model Content

[0004] In view of this, the present invention provides a mechanical breaker for aqueduct demolition, aiming to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A mechanical breaker for aqueduct demolition, comprising:

[0007] Crusher;

[0008] Dust collection assembly; the dust collection assembly includes a connecting frame fixedly connected to the bottom of the outer side of the crusher, the connecting frame having a ventilation hole inside, a centrifugal suction fan installed on the outer side of the crusher, and a suction pipe fixedly connected to the input end of the centrifugal suction fan;

[0009] A water spray assembly; the water spray assembly includes an air inlet pipe fixedly connected to the output end of the connecting frame, a water storage tank fixedly connected to the end of the air inlet pipe away from the vent, and a water outlet pipe fixedly connected to the bottom end of the water storage tank.

[0010] Preferably, a filter screen is fixedly connected to one end of the suction pipe near the connecting frame, and the outer side of the suction pipe is fixedly connected to the connecting frame.

[0011] Preferably, atomizing nozzles are fixedly connected to both sides of the bottom end of the water outlet pipe, and a water inlet is fixedly connected to the outer end of the water storage tank away from the centrifugal fan.

[0012] Preferably, the inner side of the water storage tank is fixedly connected to the outer side of the connecting frame.

[0013] Preferably, the inner side of the water outlet pipe is fixedly connected to the outer side of the connecting frame.

[0014] Preferably, a crushing head is installed at the bottom of the inside of the crusher, and the outer side of the crushing head passes through the connecting frame and extends to the top to connect with the crusher.

[0015] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a mechanical breaker for aqueduct demolition, which has the following beneficial effects:

[0016] This invention involves the operator starting the crusher. Simultaneously, as the crushing head begins crushing the aqueduct, a centrifugal suction fan activates. Negative pressure is generated within the connecting frame via the suction pipe, drawing in dust generated by the crushing head and through a filter screen into the centrifugal suction fan. From the fan's output, air is transported to a water storage tank. Operating in a closed environment, the tank uses a bottom-mounted water spray assembly to deliver air to the outside. Atomizing nozzles spray liquid from the tank, forming a water barrier to reduce dust dispersion. This design, through the negative pressure generated by the centrifugal suction fan, effectively draws in dust generated during crushing operations and cleans it through the filter screen, significantly reducing dust concentration in the working environment. Furthermore, the water storage tank and atomizing nozzle design cover the crushing head's working area with a layer of spray, further reducing airborne dust dispersion and achieving environmentally friendly dust reduction.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1 As shown, this embodiment provides a technical solution: a mechanical breaker for aqueduct demolition, comprising;

[0028] Crusher 1, with a crushing head 2 installed at the bottom of its interior;

[0029] As the core equipment of the entire hydraulic breaker, the crusher 1 crushes the trough through its internal crushing head 2. The crushing head 2 is installed at the bottom of the inside of the crusher 1 and is the part that directly contacts and crushes the trough.

[0030] like Figure 1 - Figure 4 As shown, the dust collection assembly 3 includes a connecting frame 31 fixedly connected to the bottom of the outer side of the crusher 1. The outer side of the crushing head 2 passes through the connecting frame 31 and extends to the top to connect with the crusher 1. A ventilation hole 32 is opened inside the connecting frame 31. A centrifugal suction fan 33 is installed on the outer side of the crusher 1. A suction pipe 34 is fixedly connected to the input end of the centrifugal suction fan 33. A filter screen 35 is fixedly connected to one end of the suction pipe 34 near the connecting frame 31. The outer side of the suction pipe 34 is fixedly connected to the connecting frame 31.

[0031] The connecting frame 31 is fixed to the bottom of the outer side of the crusher 1, providing structural support for the dust collection component 3. The outer side of the crushing head 2 passes through the connecting frame 31 to ensure a stable connection between the dust collection component 3 and the crusher 1, resulting in better dust collection. The vent 32 is opened inside the connecting frame 31 to guide airflow, making the dust collection process smoother and improving dust collection efficiency. The centrifugal fan 33 is installed on the outside of the crusher 1 and sucks in the dust generated during the crushing process through the suction pipe 34. The strong suction can collect dust in time and reduce dust diffusion. The suction pipe 34 connects the centrifugal fan 33 and the filter screen 35 to ensure gas flow in the connecting frame 31. The filter screen 35 is fixedly connected to the end of the suction pipe 34 near the connecting frame 31 to filter the sucked air, effectively intercepting dust and preventing it from entering the fan, thus extending the service life of the equipment.

[0032] like Figure 1 - Figure 4 As shown, the water spray assembly 4 includes an air inlet pipe 41 fixedly connected to the output end of the connecting frame 31. A water storage tank 42 is fixedly connected to the end of the air inlet pipe 41 away from the air vent 32. The inner side of the water storage tank 42 is fixedly connected to the outer side of the connecting frame 31. A water outlet pipe 43 is fixedly connected to the bottom end of the water storage tank 42. The inner side of the water outlet pipe 43 is fixedly connected to the outer side of the connecting frame 31. Atomizing nozzles 44 are fixedly connected to both sides of the bottom end of the water outlet pipe 43. A water inlet 45 is fixedly connected to the outer side of the water storage tank 42 away from the centrifugal fan 33.

[0033] The air inlet pipe 41 connects the vent 32 to the water storage tank 42, providing an airflow channel for the water storage tank 42. The air pressure provided by the centrifugal suction fan 33 ensures that the water in the water storage tank 42 can be smoothly sprayed out under pressure, enhancing the atomization effect of the water spray and improving the dust reduction efficiency. The water storage tank 42 stores water for water spraying and dust reduction, and can continuously supply water to ensure the stable operation of the water spraying component 4 during the crushing process and reduce dust diffusion. The water outlet pipe 43 delivers the water in the water storage tank 42 to the atomizing nozzle 44 to realize the water spraying function. The atomizing nozzle 44 atomizes the water flow and sprays it out, directly acting on the crushing area. The atomized water can effectively reduce the dust generated during the crushing process, reduce the harm to the environment and the health of operators, and the design of the atomizing nozzle 44 can expand the water spraying coverage area and improve the dust reduction efficiency. The water inlet 45 replenishes water to the water storage tank 42, making it convenient for operators to replenish the water source at any time and extend the continuous operation time of the equipment.

[0034] Working principle:

[0035] like Figure 1 - Figure 4 As shown:

[0036] In operation: First, the operator needs to start the crusher 1. At this time, the crushing head 2 will begin crushing the aqueduct. Simultaneously, the centrifugal suction fan 33 will also start. During the start-up process of the centrifugal suction fan 33, the air inside the connecting frame 31 will be negatively pressured through the suction pipe 34. Dust generated by the crushing head 2 during the crushing operation will pass through the negative pressure environment inside the connecting frame 31 and then flow in through the vent 32. This dust will remain in the connecting frame 31 due to the isolation effect of the filter screen 35, and the air will be drawn in by the centrifugal suction fan 33. The air enters the air intake pipe 41 and is then transported through the air intake pipe 41 connected to the output end of the centrifugal fan 33 to the interior of the water storage tank 42. Since the water storage tank 42 is in a closed environment during operation, as the internal air pressure increases, it will be transported to the outside through the water spray component 4 of the crusher 1 at the bottom. In this way, the liquid inside the water storage tank 42 is sprayed out through the atomizing nozzle 44, and the atomized nozzle 44 sprays out into the working area of ​​the crusher head 2, forming a water barrier, thereby further reducing the spread of dust and achieving the effect of environmental protection.
