Description

Technical Field

[0001] The utility model relates to the technical field of waste gas combustion treatment devices, in particular to waste gas treatment equipment for an oxygen-enriched combustion furnace. Background Art

[0002] Oxygen-enriched combustion is a highly efficient energy-saving combustion technology that uses oxygen-containing gas with a higher oxygen content than air (20.947%) to greatly reduce the amount of nitrogen oxides produced by oxidation of nitrogen in the air during the combustion process, thereby achieving the goal of low nitrogen emissions.

[0003] There are some devices for treating exhaust gas in the prior art, such as a utility model patent document with authorization announcement number "CN219682016U" and patent name "A Gas Filtering Device", which discloses an exhaust gas treatment device, the device includes a filter box, a plurality of filter mechanisms are arranged inside the filter box, and a locking mechanism is arranged on the top of each of the plurality of filter mechanisms. The filter mechanism includes a filter cover, a mounting frame is arranged inside the filter cover, and limit rods are fixedly connected to both sides of the filter cover.

[0004] However, when replacing the filter mechanism of the above-mentioned device, since the filter mechanism needs to be taken out from the filter box, the equipment usually needs to be shut down for the replacement operation, and the shutdown of the equipment will greatly affect the work efficiency; if the device is not shut down, since the filter box is open during the removal process, the process will cause a large amount of gas being filtered to escape, affecting the normal filtering work of the device and reducing its practicality. Utility Model Content

[0005] In view of the deficiencies existing in the prior art, the utility model provides an oxygen-enriched combustion furnace waste gas treatment device, which is used to solve the technical problem that some oxygen-enriched combustion furnace waste gas treatment devices mentioned in the background technology need to take out the filter mechanism from the filter box when replacing the filter mechanism, and usually the equipment needs to be shut down for the replacement operation, and the equipment shutdown will greatly affect the work efficiency; if the equipment is not shut down, since the filter box is open during the removal process, the process will cause a large amount of gas being filtered to escape, affecting the normal filtering work of the device and reducing the practicality.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] An oxygen-enriched combustion furnace waste gas treatment device comprises a filter box and an air inlet pipe and an air outlet pipe which are connected to and penetrated on two sides opposite to the filter box. A filter plate which can slide out of the filter box is arranged in the filter box, and folding baffles are arranged on both sides of each filter plate. The filter plate and the folding baffles are connected by a sliding guide assembly. When the filter plate is pulled out of the filter box, the sliding guide assembly drives the folding baffle to unfold and divide the filter box into multiple spaces. When the filter plate is inserted into the filter box, the sliding guide assembly drives the folding baffle to contract to make the spaces penetrated.

[0008] Working principle:

[0009] When in use, the filtered gas enters the filter box from the air inlet pipe, passes through the filter plate and flows out from the air outlet pipe;

[0010] When the filter plate needs to be replaced, the staff pulls the filter plate. As the filter plate moves, the sliding guide assembly drives the folding baffle to unfold and divide the filter box into multiple spaces. At this time, the gas entering the filter box from the air inlet pipe is blocked by the folding baffle, so the gas will not escape from the filter box in large quantities. Then the staff replaces the filter plate outside the filter box.

[0011] After the replacement is completed, the staff pushes the filter plate into the filter box. At this time, the sliding guide assembly drives the folding baffle to shrink, the space in the filter box is connected, and the filtered gas is filtered through the new filter plate.

[0012] Beneficial effects:

[0013] In this scheme, by setting up a filter box, an air inlet pipe, an air outlet pipe and a filter plate, the filtered gas enters the filter box from the air inlet pipe, flows out from the air outlet pipe after filtering through the filter plate, thereby filtering the gas;

[0014] By setting up a folding baffle and a sliding guide assembly, when replacing the filter plate, the staff pulls the filter plate. As the filter plate moves, the sliding guide assembly drives the folding baffle to unfold and divide the filter box into multiple spaces. At this time, the gas entering the filter box from the air inlet pipe is blocked by the folding baffle, so the gas will not escape from the filter box in large quantities to affect the normal replacement work of the staff. Therefore, there is no need to shut down the equipment, exhaust all the gas and then replace the filter plate. This method reduces the impact on work efficiency to a certain extent and improves practicality. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0022] Example:

[0023] like Figure 1 and Figure 2 As shown, an oxygen-enriched combustion furnace waste gas treatment equipment includes a filter box 1 and an air inlet pipe 18 and an air outlet pipe 19 which are connected to the filter box 1 on both sides opposite to the filter box 1. The filter box 1 is provided with a filter plate 2 which can slide out of the filter box 1. Folding baffles 3 are provided on both sides of each filter plate 2. The filter plate 2 and the folding baffles 3 are connected by a sliding guide assembly; when the filter plate 2 is pulled out of the filter box 1, the sliding guide assembly drives the folding baffles 3 to unfold and divide the filter box 1 into multiple spaces; when the filter plate 2 is inserted into the filter box 1, the sliding guide assembly drives the folding baffles 3 to contract to make the spaces connected.

[0024] In this solution, by setting up a filter box 1, an air inlet pipe 18, an air outlet pipe 19 and a filter plate 2, the filtered gas enters the filter box 1 from the air inlet pipe 18, flows out from the air outlet pipe 19 after filtering by the filter plate 2, thereby filtering the gas; by setting up a folding baffle 3 and a sliding guide assembly, when replacing the filter plate 2, the staff pulls and pulls the filter plate 2, and as the filter plate 2 moves, the sliding guide assembly drives the folding baffle 3 to unfold and divide the filter box 1 into multiple spaces. At this time, the gas entering the filter box 1 from the air inlet pipe 18 is blocked by the folding baffle 3, so the gas will not escape from the filter box 1 in large quantities, affecting the normal replacement work of the staff. Therefore, there is no need to shut down the equipment, exhaust all the gas and then replace the filter plate 2. This method reduces the impact on work efficiency to a certain extent and improves practicality.

[0025] like Figure 1 and Figure 2 As shown, the filter box 1 is formed by a filter chamber and a storage chamber being connected through, the sliding guide assembly comprises two first mounting blocks 4, two second mounting blocks 6, two telescopic rods 8, two fixed shafts 12, a main slide rail 9 and two side slide rails 10 arranged on both sides of the main slide rail 9, the two first mounting blocks 4 are respectively fixedly arranged on both sides of the bottom of the filter plate 2, the first mounting blocks 4 are rotatably mounted with a first rotating shaft 5, the two second mounting blocks 6 are respectively fixedly arranged on the side walls of the two folding baffles 3, the second mounting blocks 6 are rotatably mounted with a second rotating shaft 7, the two telescopic rods 8 are fixedly sleeved between the first rotating shaft 5 and the second rotating shaft 7 on the same side in a one-to-one manner, the fixed shaft 12 is vertically fixedly arranged on the bottom wall of the filter box 1 and passes through the telescopic rod 8, the telescopic rod 8 can rotate relative to the fixed shaft 12, the main slide rail 9 and the two side slide rails 10 are parallel, the filter plate 2 is slidably arranged on the main slide rail 9, and the two folding baffles 3 arranged on both sides of the filter plate 2 are slidably arranged on the two side slide rails 10.

[0026] By arranging two first mounting blocks 4, two second mounting blocks 6, two telescopic rods 8, two fixed shafts 12, a main slide rail 9 and two side slide rails 10 arranged on both sides of the main slide rail 9, when the staff pulls out the filter plate 2, the telescopic rod 8 is extended and retracted and drives the folding baffle 3 to unfold. This method of unfolding the folding baffle 3 in the process of pulling out the filter plate 2 has a linkage effect and improves work efficiency.

[0027] like Figure 1 to Figure 3 As shown, the storage chamber is used to place the folding baffle 3 in the folded state, each of the folding baffles 3 is composed of a plurality of working baffles 20 rotatably connected, and each of the working baffles 20 is rotated by means of hinges. This rotation method belongs to the prior art and will not be repeated here. A mounting shaft 11 is fixed to the bottom of each working baffle 20, and the side slide rails 10 of the filter chamber extend into the storage chamber. The mounting shaft 11 is slidably arranged in the side slide rails 10 of the filter chamber and the storage chamber. A first magnetic block 13 is fixedly arranged at one end of each of the folding baffles 3, and a plurality of second magnetic blocks 14 are fixedly arranged on the inner wall of the storage chamber. The second magnetic block 14 is used to attract the corresponding first magnetic block 13 when the folding baffle 3 is opened.

[0028] By setting the working baffle 20, the storage chamber, the filter chamber, the installation shaft 11, the first magnetic block 13 and the second magnetic block 14, when the folding baffle 3 is unfolded, the working baffle 20 rotates and rotates around the installation shaft 11, and the installation shaft 11 slides along the side slide rail 10. At this time, the unfolded folding baffle 3 is a horizontal plate parallel to the direction of the side slide rail 10, thereby dividing the space in the filter box 1.

[0029] like Figure 4 As shown, the main slide rail 9 of the filter chamber extends into the storage chamber, and the filter plate 2 is a hollow structure. The hollow structure of the filter plate 2 is used to place the filter plate body 16, and the filter plate body 16 is snap-fitted into the hollow structure of the filter plate 2. A handle 15 is provided on the filter plate 2, and the handle 15 is provided on the outside of the filter box 1. By providing the handle 15, it is convenient for the staff to pull out the filter plate 2 by holding the handle 15. Figure 5 As shown, a dust collecting groove 17 is slidably provided at the bottom of the filter plate 2, and both sides of the dust collecting groove 17 are opened upward and the openings face the two sides of the filter plate 2. The dust collecting groove 17 is slidably provided at the bottom of the main slide rail 9 and can slide out of the filter box 1.

[0030] As time goes by, a lot of dust will accumulate on the filter plate 2, and the dust will fall into the filter box 1. By setting up the dust collecting trough 17, the fallen dust can be collected, and the staff does not need to clean the inside of the filter box 1 regularly, thereby reducing the labor intensity of the staff.

[0031] Working principle:

[0032] When in use, the filtered gas enters the filter box 1 from the air inlet pipe 18, and flows out from the air outlet pipe 19 after being filtered by the filter plate 2;

[0033] When the filter plate 2 needs to be replaced, the staff member holds the handle 15 to pull the filter plate 2. As the filter plate 2 moves, the telescopic rod 8 is driven to shrink. The shrinkage of the telescopic rod 8 drives the working baffle 20 connected to the second mounting block 6 to rotate. The mounting shaft 11 rotatably connected to the working baffle 20 slides along the side slide rail 10. The movement of the working baffle 20 drives the other working baffle 20 rotatably connected to the working baffle 20 to move, thereby the folding baffle 3 is unfolded. Finally, the first magnetic block 13 and the second magnetic block 14 attract each other to separate the filter box 1 into multiple spaces. At this time, the gas entering the filter box 1 from the air inlet pipe 18 is blocked by the folding baffle 3.

[0034] Then the staff inserts the new filter plate 2 body into the hollow structure of the filter plate 2;

[0035] Then the staff pushes the filter plate 2 back into the filter box 1 again through the handle 15, which drives the folding baffle 3 to shrink in the process, and the folding baffle 3 shrinks back into the storage chamber. At this time, the space in the filter box 1 is connected, and the filtered gas is filtered through the new filter plate 2 and then flows out from the outlet pipe 19, and the whole operation is completed.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
