[0019] The present invention will be further described below in detail with reference to the accompanying drawings and specific embodiments, but the scope of implementation of the present invention is not limited thereto.

[0020] like Figures 1 to 2As shown, a fume purification device for a die-casting machine described in this embodiment includes a device body 1, a purification channel is provided in the device body 1, an air inlet 11 connected to one end of the purification channel is provided on one side of the device body 1, an air outlet 12 connected to the other end of the purification channel is provided on the top of the device body 1, and an exhaust fan (not shown in the figure) is provided near the exhaust port 12 of the device body 1; a primary filter 2 is provided near the air inlet 11 of the device body 1;

[0021] A low-pressure purification electric field 3 and a high-pressure purification electric field 4 are arranged above the primary filter 2 along the trajectory of the purification channel in the equipment body 1, and the equipment body 1 is provided with a spray cleaning mechanism above the low-pressure purification electric field 3 and above the high-pressure purification electric field 4.

[0022] Specifically, when the die-casting machine fume purification equipment of this embodiment is actually used, the exhaust fan works to continuously generate airflow in the purification channel, so that the fume generated by the die-casting machine enters the purification channel through the air inlet 11. The fume entering the purification channel first passes through the primary filter 2, which filters the fine particulate matter, dust, odor, harmful gases and bacteria in the fume. Then the fume enters the high-voltage purification electric field 4, which adsorbs the larger oil particles in the fume, and at the same time makes the fine particles in the fume carry an electric charge, and a small number of micro particles are removed. Small oil particles are adsorbed onto the plates of the high-voltage purification electric field 4 under the action of the electric field force and the airflow. At the same time, the high-voltage purification electric field 4 degrades some of the tiny oil particles into carbon dioxide and water, and generates ozone in the air within the high-voltage purification electric field 4, thereby removing most of the odor in the flue gas. The flue gas then enters the low-voltage purification electric field 3, which adsorbs the tiny oil particles in the flue gas, which can be as small as 0.01 microns, thereby purifying the flue gas and obtaining purified clean air. The purified clean air is discharged from the exhaust port 12.

[0023] When the oil particles adsorbed on the plates of the low-pressure purification electric field 3 and the high-pressure purification electric field 4 accumulate to a certain extent, the plates of the low-pressure purification electric field 3 and the high-pressure purification electric field 4 are spray-cleaned by the spray cleaning mechanism respectively to remove the oil and dirt adsorbed in the electric field, so as to ensure the adsorption capacity of the low-pressure purification electric field 3 and the high-pressure purification electric field 4.

[0024] This embodiment achieves multi-stage purification by arranging a low-pressure purification electric field 3 and a high-pressure purification electric field 4 spaced apart in the purification channel, thereby improving the purification efficiency and purification effect of the flue gas, and arranging a spray cleaning mechanism above the low-pressure purification electric field 3 and above the high-pressure purification electric field 4, respectively, so that the low-pressure purification electric field 3 and the high-pressure purification electric field 4 can be automatically cleaned by the spray cleaning mechanism to ensure the adsorption capacity of the low-pressure purification electric field 3 and the high-pressure purification electric field 4 for long-term use, thereby improving the adsorption effect and reducing the maintenance cost of the purification equipment.

[0025] like Figure 1 and Figure 2 As shown, in some embodiments of the die-casting machine fume purification equipment described in this embodiment, the spray cleaning mechanism includes a waterway pipe 51 and a plurality of spray nozzles 52 spaced apart along the length of the waterway pipe 51. Specifically, during use, a high-pressure water flow is delivered to each spray nozzle 52 through the waterway pipe 51, and the high-pressure water flow is ejected from the spray nozzles 52 toward the low-pressure purification electric field 3 or the high-pressure purification electric field 4, thereby cleaning the low-pressure purification electric field 3 and the high-pressure purification electric field 4. Manual disassembly and cleaning are unnecessary, which helps reduce the maintenance cost of the purification equipment.

[0026] like Figure 1 As shown, a die-casting machine fume purification device described in this embodiment, in some embodiments, a circulating water tank 6 and a circulating water pump 7 are provided at the bottom of the device body 1; the circulating water tank 6 is located below the primary filter 2, and the circulating water pump 7 is arranged on one side of the circulating water tank 6, the water inlet end of the circulating water pump 7 is connected to the circulating water tank 6, and the water outlet end of the circulating water pump 7 is connected to the waterway pipe 51.

[0027] Specifically, this embodiment sets up a circulating water tank 6 to store cleaning water, and pumps the cleaning water in the circulating water tank 6 into the water pipe 51 through the circulating water pump 7, and then sprays it out through each spray nozzle 52, thereby realizing the cleaning process. The liquid after cleaning falls back into the circulating water tank 6 under its own weight, so that the cleaning water can be recycled, which is more economical and environmentally friendly.

[0028] In some embodiments of the die-casting machine fume purification device described in this embodiment, the electrode plates of the low-voltage purification electric field 3 and the electrode plates of the high-voltage purification electric field 4 are both made of stainless steel. This arrangement ensures uniform discharge between the low-voltage purification electric field 3 and the high-voltage purification electric field 4.

[0029] In some embodiments of the die-casting machine fume purification device described in this embodiment, the device body 1 is provided with oil drainage channels (not shown in the figure) below the electrode plates of the low-voltage purification electric field 3 and below the electrode plates of the high-voltage purification electric field 4, respectively. The oil drainage channels are connected to an oil collection pan (not shown in the figure) fixedly mounted on the device body 1. In this embodiment, the oil collection pan and the oil drainage channels are provided so that oil and dirt adsorbed on the electrode plates of the low-voltage purification electric field 3 and the high-voltage purification electric field 4 fall into the oil drainage channels under their own weight. The oil is then guided by the oil drainage channels and flows into the oil collection pan for collection, allowing the user to centrally process the oil.

[0030] In some embodiments of the die-casting machine fume purification device described in this embodiment, the primary filter 2 includes a particulate filter (not shown) and a gaseous pollutant filter (not shown). By providing the particulate filter and the gaseous pollutant filter, this embodiment filters out fine particles, dust, odors, harmful gases, and bacteria in the fume, thereby discharging clean air.

[0031] In some embodiments of the die-casting machine fume purification device described in this embodiment, the particle filter includes a coarse filter (not shown) and a fine particle filter (not shown). This embodiment uses the coarse filter and the fine particle filter to filter particles of different sizes in the fume, thereby improving the filtration effect.

[0032] like Figure 1 and Figure 2 As shown, in some embodiments of the die-casting machine fume purification device described in this embodiment, support legs 13 are fixedly installed at the four corners of the bottom of the device body 1. In this embodiment, the support legs 13 are provided to support the purification device so that the purification device can be fixedly placed on an external mounting surface.

[0033] like Figure 2 As shown, in some embodiments of the die-casting machine fume purification device described in this embodiment, the device body 1 is provided with an electric control box 8 corresponding to the low-voltage purification electric field 3 and the high-voltage purification electric field 4. In this embodiment, the electric control box 8 is provided to facilitate user control of the low-voltage purification electric field 3 and the high-voltage purification electric field 4.

[0034] The above is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, features and principles described in the scope of the present invention patent application are included in the scope of protection of the present invention patent application.
