Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust removal equipment technology, and in particular to a dust removal equipment with a function of preventing liquid splashing. Background Technology
[0002] Dust removal equipment mainly consists of a fan and a filtration mechanism. The function of the fan is to generate flowing gas, which transports dust in the air to the filtration mechanism. The filtration mechanism usually adsorbs dust through filter screens, cloth bags, or aqueous solutions.
[0003] In existing technologies, when dust is transported into an aqueous solution, the gas impacts the solution. The violent disturbances caused by the transfer of gas kinetic energy to the liquid and the energy released by the bursting of bubbles cause the aqueous solution to splash. If the aqueous solution splashes out of the pool, the liquid level in the pool will gradually drop, reducing the dust collection capacity of the aqueous solution. Therefore, water needs to be added to the pool, increasing resource consumption and thus increasing the cost of dust removal. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dust removal device with a function to prevent liquid splashing.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a dust removal device with a function to prevent liquid splashing, including a filter box, a dust suction mechanism connected to the side of the filter box, a dust collection pool provided below the filter box, two layers of mesh plates inside the filter box, a plurality of stacked PVC multi-faceted hollow spheres between the two layers of mesh plates, and a plurality of first exhaust pipes installed through the bottom of the filter box, the bottom ends of the plurality of first exhaust pipes extending into the dust collection pool.
[0006] Preferably, a second exhaust pipe is installed at the bottom of each of the first exhaust pipes, the second exhaust pipe is located in the dust collection water tank, and a perforated plate is matched and installed at the bottom of the second exhaust pipe.
[0007] Preferably, the interior of the second exhaust duct is equipped with multiple baffles, which are arranged sequentially from top to bottom.
[0008] Preferably, a fixing ring is installed at the top of the second exhaust duct, and a rubber sealing gasket is provided at the top of the fixing ring, with the top of the rubber sealing gasket contacting the bottom of the second exhaust duct.
[0009] Preferably, the dust collection mechanism includes a fan, the exhaust pipe of which is installed through the side of the filter box, the air inlet pipe of which is connected to an air duct, and multiple dust collection hoods are installed through the surface of the air duct.
[0010] Compared with the prior art, the present invention has the following beneficial effects:
[0011] This solution involves placing multiple PVC hollow spheres in the filter box, positioned along the gas flow path. The numerous blades of these spheres create resistance to the gas flow, slowing its velocity and reducing the impact of the gas on the water solution. This reduces the disturbance caused by the gas impact, thus mitigating bubble formation and lowering the likelihood of wastewater spraying out of the tank. This allows the water solution to remain stably in the dust collection tank, thereby reducing dust removal costs. Attached Figure Description

[0015] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.
[0016] like Figure 1 The dust removal device shown includes a filter box 5 with a dust collection mechanism connected to the side of the filter box 5. The dust collection mechanism includes a fan 8, the exhaust pipe of the fan 8 is installed through the side of the filter box 5, and the air inlet pipe of the fan 8 is connected to a duct 6. Multiple dust collection hoods 7 are installed through the surface of the duct 6. The dust collection hoods 7 can effectively control the diffusion of dust-laden airflow during the air extraction process of the fan 8, preventing dust from spreading to the production workshop and the atmosphere. The duct 6 is used to collect the dust-laden airflow conveyed by the multiple dust collection hoods 7, which facilitates the concentration of the dust-laden airflow and its delivery to the filter box 5 through the fan 8. The fan 8, as the power source for the gas flow, is an important driving component.
[0017] Below the filter box 5 is a dust collection water tank 9, in which the aqueous solution stored is used to finally adsorb dust in the gas.
[0018] The filter box 5 has two layers of mesh plates 3 inside, and multiple stacked PVC multifaceted hollow spheres 4 are placed between the two layers of mesh plates 3. Multiple first-row air ducts 1 are installed through the bottom of the filter box 5. The two layers of mesh plates 3 play a role in stabilizing the position of the multiple PVC multifaceted hollow spheres 4 and preventing the PVC multifaceted hollow spheres 4 from falling out of the multiple first-row air ducts 1. During the process of gas friction on the surface of PVC multifaceted hollow spheres 4, static electricity is generated on the surface of PVC multifaceted hollow spheres 4. Static electricity will attract charged dust particles in the gas, thereby achieving a preliminary dust removal effect.
[0019] The bottom ends of multiple first exhaust ducts 1 extend into the dust collection water tank 9, so that the dust-laden airflow is dispersed and discharged into the aqueous solution of the dust collection water tank 9 through multiple first exhaust ducts 1, achieving the final dust removal effect.
[0020] Each of the first-row air ducts 1 has a second-row air duct 10 installed at its bottom end. The top end of the second-row air duct 10 has a first thread inside, and the bottom end of the first-row air duct 1 has a second thread outside. The first thread and the second thread are connected to each other, which makes it easy to install and disassemble the second-row air duct 10 and the first-row air duct 1, and facilitates the operation of the staff.
[0021] The second exhaust duct 10 is located in the dust collection water tank 9. A perforated plate 11 is installed at the bottom of the second exhaust duct 10. When the gas in the second exhaust duct 10 is discharged into the aqueous solution through multiple holes in the perforated plate 11, it disperses a large airflow into multiple airflows and delivers them into the aqueous solution, thereby generating multiple fine bubbles. The small bubbles have a larger specific surface area, their rising speed is slower than that of the large bubbles, they stay in the liquid for a longer time, and release less energy when they burst, further reducing the possibility of splashing of the aqueous solution.
[0022] The second-row air duct 10 has multiple baffles 12 installed inside. The baffles 12 are arranged from top to bottom and are truncated cone-shaped. The radial dimension of the inner cavity of the baffle 12 gradually increases from top to bottom. As the gas flows through the inner cavity of the baffle 12, the flow space gradually expands, which gradually slows down the gas flow rate and is used to further control the gas flow rate.
[0023] A fixing ring 13 is installed at the top of the second exhaust duct 10. A rubber sealing gasket 2 is provided at the top of the fixing ring 13. The top of the rubber sealing gasket 2 contacts the bottom of the second exhaust duct 10. The rubber sealing gasket 2 increases the sealing between the second exhaust duct 10 and the first exhaust duct 1, preventing gas from leaking from the gap between the second exhaust duct 10 and the first exhaust duct 1, and improving the stability of gas flow in the second exhaust duct 10 and the first exhaust duct 1. The fixing ring 13 fixes the position of the rubber sealing gasket 2, improving the tightness of the contact between the rubber sealing gasket 2 and the first exhaust duct 1.
[0024] Working principle: When performing dust removal, the fan 8 is first powered on. Dust from the external environment is transported to the filter box 5 by the flowing gas through the dust collection hood 7, the air duct 6 and the fan 8. During the friction of multiple gases on the surface of the PVC multifaceted hollow sphere, static electricity is generated on the surface of the PVC multifaceted hollow sphere. The static electricity will adsorb charged dust particles in the gas, thus performing preliminary dust removal. At the same time, because the PVC multifaceted hollow sphere has many blades, it creates resistance to the gas and initially slows down the gas flow rate.
[0025] The dust-laden airflow in the filter box 5 is discharged into multiple second-stage air ducts 10 through multiple first-stage air ducts 1. During the flow of the gas in the inner cavity of the baffle 12, the flow space gradually expands, causing the gas flow rate to gradually slow down, which is used to further control the flow rate of the dust-laden airflow. When the dust-laden airflow is finally discharged into the aqueous solution through multiple holes in the perforated plate 11, a large dust-laden airflow is dispersed into multiple airflows and transported into the aqueous solution, thereby generating multiple fine bubbles. The small bubbles have a larger specific surface area, their rising speed is slower than that of the large bubbles, they stay in the liquid for a longer time, and release less energy when they burst, further reducing the possibility of aqueous solution splashing. This ensures the stability of the liquid level in the dust collection pool, avoids the waste of water resources, and reduces the cost of dust removal.
