Description

Technical Field

[0001] The utility model relates to the technical field of rotary RTO, in particular to a rotary RTO which is easy to repair. Background Art

[0002] The rotary RTO is an upgraded RTO device based on the RTO thermal storage combustion, also known as a rotary thermal storage oxidizer. The principle of the rotary RTO is to oxidize the combustible waste gas into the corresponding oxides and water at high temperature, thereby purifying the waste gas and recovering the heat released during the decomposition of the waste gas. The waste gas decomposition efficiency reaches over 99.5%, and the heat recovery efficiency reaches over 97%. When the waste gas concentration is high, a waste heat recovery boiler can be configured to use the waste gas as fuel, turning waste into treasure. Waste heat recovery can be rotated: hot air, hot water, steam and thermal oil;

[0003] A Chinese patent (patent number: CN218011779U, disclosing a rotary RTO that is easy to maintain) discloses a rotary RTO that is easy to maintain. By rotating the round rod, the brush bar physically contacts and cleans the adjacent filter screens, so that the particles adsorbed on the filter mesh are separated from the surface of the filter screen, simplifying the steps for personnel to repair the exhaust pipe on the RTO body, reducing the maintenance time of the personnel, and improving the work efficiency of the personnel. At the same time, the personnel do not need to repeatedly rotate different round rods multiple times, and can drive multiple brush bars to clean the filter screens at the same time, saving the personnel's physical strength.

[0004] However, when the above device is in use, since the brush rod is a roller-shaped structure and the filter is a flat plate structure, when the brush rod rotates, it cannot contact the two sides of the filter, and the closer it is to the two sides, the smaller the friction between the brush and the filter. Therefore, there is a problem that dead corners cannot be cleaned and the cleaning effect is poor. Utility Model Content

[0005] The purpose of the utility model is to provide a rotary RTO which is easy to maintain and has the characteristics that the brush can fully contact with any position of the filter screen, thereby improving the cleaning effect and avoiding the occurrence of dead corners that cannot be cleaned.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a rotary RTO that is easy to maintain, comprising an RTO body, an exhaust device installed on the outer wall of the RTO body, the exhaust device comprising an exhaust pipe, a filter screen fixedly connected to the interior of the exhaust pipe, a rotating shaft rotatably connected to the interior of the exhaust pipe, a cleaning frame fixedly connected to the outer wall of the rotating shaft, brushes fixedly connected to the left and right sides of the cleaning frame, a front end of the rotating shaft extends to the outside of the exhaust pipe and is fixedly connected to a connecting cylinder, the outer wall of the connecting cylinder is fixedly connected to a crank, the outer wall of the connecting cylinder is fixedly connected to a limit rod arranged perpendicular to the crank, the outer wall of the exhaust pipe is fixedly connected to two sliding rods, the outer walls of the two sliding rods are slidably connected to sliders, and a limiting cylinder is fixedly connected between the two sliders.

[0007] In order to expand the cleaning range and improve the cleaning effect, as a preferred rotary RTO that is easy to maintain in the present invention, the filter screen is an arc-shaped structure and the center point of the arc coincides with the rotating shaft.

[0008] In order to facilitate the placement of the brush, as a preferred rotary RTO for easy maintenance of the present invention, the left and right sides of the outer wall of the exhaust pipe are fixedly connected to the expansion cavity, and the two brushes extend into the interior of the two expansion cavities respectively.

[0009] In order to collect particulate impurities, as a preferred embodiment of the present invention as a rotary RTO that is easy to maintain, the bottom of the exhaust pipe is threadedly connected to a collection box.

[0010] In order to facilitate exhaust, as a preferred rotary RTO that is easy to maintain in the present invention, the outer wall of the exhaust pipe is fixedly connected to a connecting pipe that is arranged obliquely, and the other end of the connecting pipe is connected to the RTO body.

[0011] In order to improve the cleaning effect of the brush, as a preferred embodiment of the rotary RTO that is easy to maintain in the present invention, the brush is made of flexible plastic material.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] When inspecting and repairing the work, there is no need to disassemble the exhaust passage. The connecting cylinder is rotated by the external crank handle. The connecting cylinder drives the rotating shaft to rotate. The rotating shaft further drives the cleaning frame on its outer wall to rotate. The cleaning frame drives the side brush to rotate, and the brush can clean the filter so that the particles adsorbed on the filter mesh are separated from the surface of the filter. Since the filter is an arc-shaped structure and the center point of the arc coincides with the rotating shaft, when the cleaning frame is continuously rotated, the brush can fully contact any position of the filter, thereby improving the cleaning effect and avoiding dead corners that cannot be cleaned. When the cleaning work is completed, rotate the connecting cylinder so that the limit rod on its outer wall faces the limit cylinder, and then slide the limit cylinder to the left so that the limit cylinder is sleeved on the outer wall of the limit rod, thereby limiting and fixing the position of the connecting cylinder, thereby fixing the rotating shaft and the cleaning frame, and not affecting the normal exhaust and filtering work.

The exhaust device 2 includes an exhaust pipe 3. A filter screen 4 is fixedly connected to the inside of the exhaust pipe 3. A rotating shaft 5 is rotatably connected to the inside of the exhaust pipe 3. A cleaning frame 6 is fixedly connected to the outer wall of the rotating shaft 5. Brushes 7 are fixedly connected to the left and right sides of the cleaning frame 6. The front end of the rotating shaft 5 extends to the outside of the exhaust pipe 3 and is fixedly connected to a connecting cylinder 10.

A limit cylinder 15 is fixedly connected between the two sliders 14.

[0021] In this embodiment, when performing maintenance, there is no need to disassemble the exhaust duct. The connecting cylinder 10 is rotated by the external crank 11, which drives the rotating shaft 5 to rotate. The rotating shaft 5 further drives the cleaning frame 6 on its outer wall to rotate. The cleaning frame 6 then drives the side brush 7 to rotate, and the brush 7 can clean the filter 4, so that particulate matter adsorbed on the mesh of the filter 4 is separated from the surface of the filter 4. When the cleaning work is completed, the connecting cylinder 10 is rotated so that the limiting rod 12 on its outer wall faces the limiting cylinder 15. The limiting cylinder 15 is then slid to the left so that the limiting cylinder 15 is sleeved on the outer wall of the limiting rod 12, thereby limiting and fixing the position of the connecting cylinder 10, thereby fixing the rotating shaft 5 and the cleaning frame 6, and not affecting the normal exhaust and filtering work.

[0022] As a technical optimization solution of the present invention, the filter screen 4 is an arc-shaped structure and the center point of the arc coincides with the rotating shaft 5 .

[0023] In this embodiment: since the filter screen 4 is an arc-shaped structure and the center point of the arc coincides with the rotating shaft 5, when the cleaning frame 6 is continuously rotated, the brush 7 can fully contact any position of the filter screen 4, thereby improving the cleaning effect and avoiding cleaning dead corners.

[0024] As a technical optimization solution of the present invention, the left and right sides of the outer wall of the exhaust pipe 3 are fixedly connected with expansion cavities 8, and the two brushes 7 extend into the interior of the two expansion cavities 8 respectively.

[0025] In this embodiment, two expansion chambers 8 are provided to accommodate the brush 7 when it is not in use, thereby avoiding squeezing the brush 7 to cause damage and extending its service life.

[0026] As a technical optimization solution of the present invention, the bottom of the exhaust pipe 3 is threadedly connected to a collecting box 9 .

[0027] In this embodiment: the bottom of the exhaust pipe 3 is threadedly connected to a collection box 9, and the particulate matter adsorbed on the mesh of the filter 4 falls down into the collection box 9 after breaking away from the filter 4, which is convenient for collection. The exhaust pipe 3 and the collection box 9 are threadedly connected, and the collection box 9 can be disassembled by rotating it for easy cleaning.

[0028] As a technical optimization solution of the present invention, an outer wall of the exhaust pipe 3 is fixedly connected to a connecting pipe 16 arranged obliquely, and the other end of the connecting pipe 16 is communicated with the RTO body 1 .

[0029] In this embodiment, the other end of the connecting pipe 16 is connected to the RTO body 1, so as to facilitate the gas to enter the exhaust pipe 3 and to facilitate exhaust.

[0030] As a technical optimization solution of the present invention, the brush 7 is made of flexible plastic material.

[0031] In this embodiment, the brush 7 is made of flexible plastic material, which is not easily deformed or damaged and is convenient for cleaning impurities.

[0032] Working principle:

[0033] When inspecting and repairing the exhaust duct, there is no need to disassemble the exhaust duct. The connecting tube 10 is rotated by the external crank 11. The connecting tube 10 drives the rotating shaft 5 to rotate. The rotating shaft 5 further drives the cleaning frame 6 on its outer wall to rotate. The cleaning frame 6 then drives the side brush 7 to rotate. The brush 7 can then clean the filter 4, allowing the particles adsorbed on the mesh of the filter 4 to separate from the surface of the filter 4. Since the filter 4 is an arc-shaped structure and the center point of the arc coincides with the rotating shaft 5, when the cleaning frame 6 is continuously rotated, the brush 7 can fully contact any position of the filter 4, thereby improving the cleaning effect and avoiding missing dead corners. When the cleaning work is completed, the connecting tube 10 is rotated so that the limit rod 12 on its outer wall faces the limit tube 15. Then, the limit tube 15 is slid to the left so that the limit tube 15 is sleeved on the outer wall of the limit rod 12, thereby limiting and fixing the position of the connecting tube 10, thereby fixing the rotating shaft 5 and the cleaning frame 6, and not affecting the normal exhaust and filtering work.
