[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] Reference Figures 1 to 5 As shown, the embodiment of the utility model provides an air intake filter device for a burner, including an air intake box 1, one side of the air intake box 1 is fixedly connected with a pipe 2, the pipe 2 conveys air to the inside of the burner to facilitate gas transmission, and a filter box 3 is installed on the other side of the pipe 2, the filter box 3 is used to filter the gas passing through, and an air intake groove 4 is arranged on the side of the filter box 3, the air intake groove 4 is opened to the inside of the filter box 3, and a baffle 5 is installed on the upper part of the air intake groove 4, the baffle 5 is used to protect the upper end of the outside of the air intake groove 4, and a box door 6 is installed at the front end of the filter box 3, and the box door 6 is opened to the inside of the filter box 3 to facilitate inspection and replacement of components in the filter box 3. A mounting base 7 is connected, and a partition plate 8 is fixedly connected to the upper part of the mounting base 7. The partition plate 8 separates and fixes the positions of a coarse filter 9 and a fine filter 10. A coarse filter 9 is installed on the side of the partition plate 8. The coarse filter 9 pre-filters the gas. The fine filter 10 is installed in the middle of the upper end of the mounting base 7. The fine filter 10 precisely filters impurities. A dust box 11 is fixedly connected to the lower part of the suction box 1. The dust box 11 absorbs impurities generated after filtration. A guide pipe 12 is fixedly connected to the lower part of the mounting base 7. The guide pipe 12 connects the gas flows to each other. A discharge pipe 13 is arranged inside the mounting base 7. The discharge pipe 13 discharges impurities generated after filtration.
[0023] like Figure 1 As shown, a pushing device is installed inside the pipeline 2, and an exhaust hole is provided outside the air suction box 1. The pushing device transports the gas to the burner inside the pipeline 2. When the burner is used, the dust generated is discharged from the exhaust hole.
[0024] like Figure 3 As shown, the coarse filter 9 is installed between the air intake groove 4 and the partition plate 8. Specifically, the coarse filter 9 is installed on the outer side of the partition plate 8, and the coarse filter 9 is located on the inner side of the air intake groove 4. After the air intake groove 4 transports the gas to the interior of the filter box 3, the gas is transported to the interior of the coarse filter 9 through the air intake groove 4. The coarse filter 9 absorbs the passing gas and pre-filters the large particle impurities contained in the gas.
[0025] like Figure 3As shown, the fine filter 10 is circular, and a plurality of fine filters 10 are provided and are evenly arranged inside the mounting seat 7. After the gas is transported to the inside of the partition plate 8, the fine filter 10 filters the pre-filtered gas again, that is, after the gas is filtered for the first time, the large particle impurities contained in the re-filtered gas are reduced. The fine filter 10 improves the filtration efficiency by filtering the gas again, and prevents large particle impurities from entering the fine filter 10 and damaging the fine filter 10, thereby increasing the service life.
[0026] like Figure 1 As shown, a protective net is installed on the outside of the air inlet groove 4, and the air inlet groove 4 is installed on both sides of the filter box 3. The protective net is installed on the outside of the air inlet groove 4 to protect from the influence of the external environment and prevent external debris from being sucked into the filter box 3 and affecting safety.
[0027] like Figure 1 As shown, the baffle 5 covers the top of the air inlet groove 4, the box door 6 is connected to the inside of the filter box 3, and the baffle 5 is installed on the top of the air inlet groove 4, thereby protecting the outside of the air inlet groove 4 from the problem of rainwater entering the inside of the filter box 3.
[0028] like Figure 4 and Figure 5 As shown, holes are provided inside the mounting base 7 and at the inner bottom of the coarse filter 9, and the two ends of the flow guide pipe 12 are respectively installed on both sides of the partition plate 8. The coarse filter 9 transports the pre-filtered gas to the inner side of the partition plate 8 through the flow guide pipe 12, and improves the filtering efficiency of the gas when transmitting the gas.
[0029] The working principle of the utility model is as follows:
[0030] When in use, start the air intake box 1, drive the air intake box 1 to absorb gas and generate suction, and then the gas is transported to the inside of the filter box 3 through the air intake groove 4. The coarse filter 9 is installed on the inner side of the air intake groove 4 and pre-filters the gas entering the air intake groove 4. The pre-filtered gas is transported to the inside of the partition plate 8 through the guide tube 12. The fine filter 10 installed in the partition plate 8 ensures sufficient air filtration by filtering the gas again, ensures air filtration efficiency, and avoids direct delivery of gas to the inside of the fine filter 10, thereby avoiding large particles of impurities directly passing through the inside of the fine filter 10 to damage the fine filter 10, thereby improving the problem of easy entry of impurities into the air intake device of the burner during use, ensuring the safety of the burner and improving the service life.
