Description

Technical Field

[0001] This utility model relates to the field of combustion furnace technology, and in particular to a combustion furnace with exhaust gas purification function. Background Technology

[0002] As living standards continue to improve, most households have gradually transitioned from using ordinary coal stoves to environmentally friendly and less polluting appliances such as natural gas stoves and induction cookers. However, in rural areas and on the outskirts of cities, incinerators are still widely used, heating cookware by burning combustibles such as wood, leaves, dry grass, straw, and cow dung. Announcement No. CN210345540U discloses a combustion furnace, including a furnace body, a combustion chamber, and an ash collection chamber connected to the combustion chamber; a pipe connected to the furnace body for discharging smoke from the furnace body; a flue on the furnace body connected to the pipe for allowing smoke from the furnace body to enter the pipe; a first smoke inlet on the furnace body connected to the flue for allowing some smoke from the combustion chamber to enter the flue; and at least one second smoke inlet on the furnace body connected to the flue for allowing another portion of smoke from the combustion chamber to enter the flue. This invention, by setting up a flue, a first smoke inlet, and a second smoke inlet, allows the airflow in the combustion chamber to be evenly diverted from the first and second smoke inlets into the flue. The fire in the combustion chamber is driven by the airflow in both directions, causing the flame, which was originally concentrated in one place, to separate, thus allowing the flame to heat the pot body evenly. However, during the use of the above technology, the device does not have the function of filtering and purifying the combustion exhaust gas. The combustion furnace produces a large amount of gas when the fuel is burned. The gas contains a large amount of particulate matter and soot. The gas will be discharged into the atmosphere through pipes, which will pollute the air and affect the air quality. Therefore, it needs to be improved. Utility Model Content

[0004] This utility model adopts the following technical solution: a combustion furnace with exhaust gas purification function, including a furnace body, a door fixedly connected to the surface of the furnace body, a square plate fixedly connected to the surface of the furnace body, an air inlet on the surface of the square plate, a partition fixedly connected between the inner walls of the furnace body, the partition dividing the interior of the furnace body into a combustion chamber and an ash removal chamber, a first exhaust pipe fixedly connected to the surface of the furnace body, a second exhaust pipe fixedly connected to one end of the first exhaust pipe, a purification component fixedly connected to one end of the second exhaust pipe, the purification component including a first shell, a second shell, and a filter screen, the filter screen being fixed inside the first shell and the second shell, a mounting base and a mounting block fixedly connected to the surfaces of the first shell and the second shell respectively, the mounting block engaging with the mounting base, a square groove being formed on the surface of the mounting block, and a fixing component being disposed inside the square groove.

[0005] Preferably, the fixing component includes a first insert block, a first spring fixedly connected to the surface of the first insert block, a second insert block fixedly connected to the other end of the first spring, a first pressure rod fixedly connected to the surface of the first insert block, and a second pressure rod fixedly connected to the surface of the second insert block. This facilitates the disassembly and assembly of the first and second housings, making it easier to clean accumulated impurities inside the first and second housings later.

[0006] Preferably, the surface of the card holder has a slot located directly below the square slot. This facilitates the insertion of the first and second insert blocks into the slot.

[0007] Preferably, the surface of the first housing has a slot, and a disc is fixedly connected to the surface of the second exhaust pipe, the disc being slidably connected inside the slot. Here, the first and second housings, which are fixedly connected to the second exhaust pipe, can be limited and fixed to prevent them from falling off the second exhaust pipe.

[0008] Preferably, a limiting groove is formed on the inner surface of the first housing, and the filter screen is inserted into the limiting groove. Here, the filter screen placed in the first and second housings can be limited to prevent it from shaking or shifting during use, so as not to affect the filtration and purification effect on the gas.

[0011] Preferably, one end of the second exhaust pipe is fixedly connected to a connecting pipe, which is inserted inside one end of the first exhaust pipe. A sleeve is fixedly connected to the surface of the first exhaust pipe, and a slider is slidably connected inside the sleeve. A rod and a pull rod are fixedly connected to the surface of the slider, and a second spring is fitted onto the surface of the pull rod. An insertion hole is formed on the surface of the connecting pipe, and the rod is inserted into the insertion hole. This facilitates the disassembly and assembly of the second and first exhaust pipes, making daily cleaning and inspection of both pipes easier. It also reduces the space occupied by the furnace body when it is not in use and is stored, as the second exhaust pipe can be removed.

[0012] Preferably, a guide groove is formed on the inner wall of one end of the first exhaust pipe, and a guide rod is fixedly connected to the surface of the connecting pipe, the guide rod being slidably connected inside the guide groove. This serves as a guide and limiter when installing and fixing the second exhaust pipe to the first exhaust pipe, allowing the insertion rod to be quickly inserted into the insertion hole and fixing the second exhaust pipe.

First, the filter screen is locked in the limiting groove on the No. 1 shell. Then, the disc at one end of the No. 2 exhaust pipe is locked in the locking groove on the No. 1 shell. Then, the No. 2 shell is closed and the first and second pressure rods on both sides of the No. 2 shell are pressed, so that the first and second insert blocks slide in the square groove in the locking block and squeeze the No. 1 spring. Then, the No. 1 spring is... The first and second insert blocks are inserted into the slots on the card holder. Then, the first and second pressure rods are released, and the first and second insert blocks are locked together with the slots under the action of the first spring. This allows the gas produced by the combustion of the furnace to be filtered and purified by setting the first shell, the second shell, and the filter screen, preventing particulate matter and smoke in the gas from being directly discharged into the air. This can greatly reduce particulate matter emissions and reduce environmental pollution. It also makes it easy to open and close the first and second shells, facilitates the cleaning of impurities accumulated in the first and second shells, and allows for quick replacement of the filter screen that has been damaged after long-term use.

[0026] Example 1

[0027] Please see Figure 1-6This utility model provides a technical solution: a combustion furnace with exhaust gas purification function, including a furnace body 1, a door 3 fixedly connected to the surface of the furnace body 1, a square plate 33 fixedly connected to the surface of the furnace body 1, an air inlet 34 opened on the surface of the square plate 33, a partition 5 fixedly connected between the inner walls of the furnace body 1, the partition 5 dividing the interior of the furnace body 1 into a combustion chamber 2 and an ash removal chamber 6, a first exhaust pipe 8 fixedly connected to the surface of the furnace body 1, a second exhaust pipe 9 fixedly connected to one end of the first exhaust pipe 8, and a purification component fixedly connected to one end of the second exhaust pipe 9, the purification component including a first shell 10, a second shell 12 and a filter screen 23, the filter screen... 23 is fixed inside the first housing 10 and the second housing 12. A retainer 14 and a retaining block 13 are respectively fixedly connected to the surfaces of the first housing 10 and the second housing 12. The retaining block 13 engages with the retainer 14. A square groove 35 is formed on the surface of the retaining block 13, and a fixing component is disposed inside the square groove 35. The fixing component includes a first insert 24, a first spring 25 is fixedly connected to the surface of the first insert 24, and a second insert 26 is fixedly connected to the other end of the first spring 25. A first pressure rod 27 is fixedly connected to the surface of the first insert 24, and a second pressure rod 28 is fixedly connected to the surface of the second insert 26. This facilitates the connection between the first housing 10 and the second housing 12. The first housing 10 and the second housing 12 are disassembled and reassembled for easy cleaning of accumulated impurities. The surface of the card holder 14 has a slot 15 located directly below the square groove 35, facilitating the insertion of the first insert 24 and the second insert 26. The surface of the first housing 10 has a slot 17. A disc 11 is fixedly connected to the surface of the second exhaust pipe 9, slidingly connected inside the slot 15. This provides a limiting and fixing mechanism for the first housing 10 and the second housing 12, preventing them from detaching from the second exhaust pipe 9. The first housing 10... A limiting groove 16 is provided on the internal surface of the chamber, and the filter screen 23 is inserted into the limiting groove 16. This groove limits the filter screen 23 placed in the first housing 10 and the second housing 12, so that it will not shake or shift during use, thus avoiding affecting the filtration and purification effect on the gas. An observation window 4 is embedded in the surface of the door 3. The observation window 4 is made of high temperature resistant transparent glass, which facilitates the observation of the fuel combustion in the combustion chamber 2 and allows for timely fuel replenishment. A collection box 7 is slidably connected inside the ash removal chamber 6, which can collect the fuel residue after complete combustion, facilitating the subsequent centralized treatment of the fuel residue.

[0028] Example 2

[0029] Please see Figure 1-6One end of the second exhaust pipe 9 is fixedly connected to a connecting pipe 19, which is inserted into the interior of one end of the first exhaust pipe 8. A sleeve 18 is fixedly connected to the surface of the first exhaust pipe 8, and a slider 29 is slidably connected inside the sleeve 18. An insertion rod 30 and a pull rod 32 are fixedly connected to the surface of the slider 29, and a second spring 31 is fitted onto the surface of the pull rod 32. An insertion hole 21 is opened on the surface of the connecting pipe 19, and the insertion rod 30 is inserted into the insertion hole 21. This facilitates the disassembly and assembly of the second exhaust pipe 9 and the first exhaust pipe 8, making it convenient for daily operation of the first exhaust pipe 8 and the second exhaust pipe. Cleaning and inspecting pipe 9 becomes easier, and it also reduces the space occupied by the second exhaust pipe 9 when the furnace body 1 is not in use and is stored. A guide groove 22 is provided on the inner wall of one end of the first exhaust pipe 8. A guide rod 20 is fixedly connected to the surface of the connecting pipe 19. The guide rod 20 is slidably connected inside the guide groove 22. This can play a guiding and limiting role when installing and fixing the second exhaust pipe 9 and the first exhaust pipe 8, so that the insertion rod 30 can be quickly inserted into the insertion hole 21 and fixed to the second exhaust pipe 9.

[0030] Working principle: During use, first place the furnace body 1 in the designated position, then assemble the exhaust pipe of the furnace body 1. The first housing 10 and the second housing 12, along with the filter screen 23, need to be installed at one end of the second exhaust pipe 9. First, insert the filter screen 23 into the limiting groove 16 on the first housing 10. Then, insert the disc 11 on one end of the second exhaust pipe 9 into the slot 17 on the first housing 10. Next, close the second housing 12 and press the first pressure rod 27 and the second pressure rod 28 on both sides of the second housing 12, causing the first insert block 24 and the second insert block 26 to slide in the square groove 35 within the locking block 13 and compress the first spring 25. Then, insert the first insert block 24 and the second insert block 26 into the square groove 35 within the locking block 13. The two insert blocks 26 are inserted into the slots 15 on the card holder 14. Then, the first pressure rod 27 and the second pressure rod 28 are released. The first insert block 24 and the second insert block 26 are then engaged with the slots 15 under the action of the first spring 25. This achieves the filtration and purification of the gas generated by combustion in the furnace body 1 through the first housing 10, the second housing 12, and the filter screen 23. This prevents particulate matter and smoke from being directly discharged into the air, significantly reducing particulate matter emissions and environmental pollution. It also facilitates the opening and closing of the first housing 10 and the second housing 12, allowing for the cleaning of accumulated impurities and addressing damage caused by prolonged use. When quickly replacing the filter 23, and then fixing the No. 2 exhaust pipe 9 to the No. 1 exhaust pipe 8, first pull the lever 32 on the sleeve 18 outwards. The lever 32 causes the slider 29 and the insertion rod 30 to slide inside the sleeve 18. Then, insert the connecting pipe 19 on the No. 2 exhaust pipe 9 into one end of the No. 1 exhaust pipe 8. The guide rod 20 on the connecting pipe 19 will be locked in the guide groove 22 on the inner wall of the No. 1 exhaust pipe 8. Then, release the lever 32. Under the action of the No. 2 spring 31, the insertion rod 30 quickly inserts into the insertion hole 21 on the connecting pipe 19, thus fixing the No. 2 exhaust pipe 9 and achieving the connection between the No. 2 exhaust pipe 9 and the No. 1 exhaust pipe 8. The process of disassembling and assembling the furnace body 1 makes it easier to clean and inspect the No. 1 exhaust pipe 8 and the No. 2 exhaust pipe 9 on a daily basis. It also reduces the space occupied by the furnace body 1 when it is not in use and is stored. Then, the fuel is placed in the combustion chamber 2 inside the furnace body 1 and ignited. The door 3 is then closed, and the combustion of the fuel can be observed through the observation window 4 on the door 3. During the combustion process, outside air can enter the interior of the furnace body 1 through the air inlet 34 on the square plate 33 to assist the combustion of the fuel. When the fuel is fully burned, the fuel residue will fall from the partition 5 into the collection box 7 in the ash removal chamber 6.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
