Description

Technical Field

[0001] This utility model relates to the field of heating furnace cleaning and maintenance technology, and in particular to a water spray nozzle for cleaning the combustion chamber of an oilfield heating furnace. Background Technology

[0002] In the oilfield extraction and production process, the heating furnace plays a crucial role, its main function being to provide the necessary thermal energy for heating and processing crude oil. The combustion chamber of the heating furnace is its core component, responsible for generating heat. However, with prolonged use, carbon deposits, dust, and other residues gradually accumulate in the combustion chamber. The accumulation of these substances not only reduces the thermal efficiency of the combustion chamber but may also lead to safety hazards, such as localized overheating and incomplete combustion.

[0003] To ensure the efficient operation and safe production of the heating furnace, regular cleaning of the combustion chamber is essential. Water spray nozzles, as specially designed cleaning tools, spray cleaning agents or water at high pressure into the combustion chamber during the cleaning process, effectively removing carbon deposits and dust. This cleaning method not only improves the cleanliness of the combustion chamber but also extends the service life of the heating furnace and reduces maintenance costs.

[0004] The existing technology has the following four limitations:

[0005] First, the existing equipment has a complex structure and is prone to jamming in high-temperature environments, which affects normal operation and increases the difficulty of maintenance.

[0006] Secondly, although the existing device is equipped with multiple nozzles, it is limited to angle changes and lacks rotation function and diverse water spraying modes, resulting in incomplete cleaning.

[0007] Third, the design of the existing equipment's delivery pipeline has defects. The pipeline material and delivery method are not clearly defined. The rubber hose may affect the water jet effect due to lack of pressure, thereby reducing the cleaning quality.

[0008] Finally, existing devices are mainly designed for cleaning the inner wall of the cavity tube, and their applicability to cleaning the combustion chamber of the heating furnace is insufficient, which limits their practical application. Summary of the Invention

[0009] (a) Technical problems to be solved

[0034] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] In the description of this utility model, it is necessary to understand that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "top", and "bottom" are all based on the orientation or positional relationship shown in the accompanying drawings. The purpose is only to facilitate the description of this utility model and simplify the description, and is not intended to indicate or imply that the indicated component must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0036] like Figure 1-4 As shown, this utility model provides a water spray nozzle for cleaning the combustion chamber of an oilfield heating furnace, comprising: a water pipe 1;

[0037] The water pipe 1 is a hollow cylindrical tubular structure. A drive assembly is fixedly connected to the outer wall of the water pipe 1. The drive assembly includes an air pump 2, which is a high-efficiency pneumatic device. The external dimensions of the air pump 2 match the internal diameter of the air inlet 3 to ensure good airtightness. The air pump 2 is in contact with the inside of the air inlet 3. The output end of the air pump 2 is fixedly connected to the outside of the water pipe 1 by means of threads or welding to facilitate the delivery of compressed air to the inside of the water pipe 1.

[0038] The water pipe 1 is provided with an air inlet 3, which is a circular through hole on the outer wall of the water pipe 1. It is equipped with threads around it so that it can be tightly connected to the air pump 2. The position and size of the air inlet 3 have been precisely calculated so as to maximize the use of airflow to assist the jet without interfering with the water flow.

[0039] The water pipe 1 has an internal cavity 4, which is cylindrical and designed to accommodate other components and ensure smooth air pressure. Limiting plates 10 are fixedly connected to the left and right sides of the cavity 4. The limiting plates 10 are annular and made of wear-resistant material to ensure stable position during long-term use. Sleeves 6 are fixedly connected inside the two limiting plates 10. The sleeves 6 are made of metal or rigid plastic tubes and are used to support the rubber tube 8. A grooved plate 5 is slidably connected to the outside of the sleeve 6. The grooved plate 5 has several protrusions that cooperate with the sleeve 6 to allow the sleeve 6 to move within a certain range but prevent it from falling out.

[0040] The outer wall of the sleeve 6 is fitted with an elastic component for providing reaction force. The elastic component includes a spring 7, which is made of high-temperature resistant material and can maintain elasticity in harsh environments. The spring 7 is located inside the cavity 4. A rubber tube 8 is fixedly connected inside the sleeve 6. The rubber tube 8 is made of high-pressure resistant material and has good flexibility and corrosion resistance. It can work stably in high-pressure water flow. Several clamping plates 9 are slidably connected to the outer wall of the sleeve 6. The clamping plates 9 are evenly distributed on the outside of the sleeve 6. The surface of each clamping plate 9 is treated with anti-slip treatment to ensure that it will not slip when subjected to pressure.

[0041] The two limiting plates 10 are the first limiting plate and the second limiting plate, respectively. The first limiting plate is located at the left end of the cavity 4, and the second limiting plate is located at the right end of the cavity 4. A sealing plate 16 is fixedly connected to the left side of the first limiting plate. The sealing plate 16 is circular and can fit tightly with the limiting plate 10 to ensure the sealing of the connection. The sealing plate 16 has a water outlet hole 11 in the center that is connected to the center of the first limiting plate, which is used to control the direction and speed of water flow.

[0042] The outer wall of the sealing plate 16 is provided with a groove 12, which is arc-shaped and used to guide the sliding trajectory of the rotating disk 13. The rotating disk 13 is slidably connected in the groove 12. The rotating disk 13 is a cylindrical structure that can rotate freely. The interior of the rotating disk 13 is provided with a water storage tank 14, which is used to temporarily store a certain amount of liquid to maintain continuous and uniform spraying.

[0043] The outer wall of the rotating disk 13 is uniformly provided with a number of nozzles 15. The nozzles 15 are connected to the water storage tank 14 inside the rotating disk 13. Each nozzle 15 is designed with a fine nozzle to adjust the shape and range of the sprayed water. The card plate 9 is slidably connected to the outer wall of the rubber tube 8. The outer wall of the card plate 9 is in contact with the inner wall of the groove plate 5, so that the card plate 9 can slide smoothly on the rubber tube 8, while contacting the inner surface of the groove plate 5 to increase stability.

[0044] The left end of the spring 7 is fixedly connected to the right end of the first limiting plate, and the right end of the spring 7 is fixedly connected to the left end of the groove plate 5, so that when the spring 7 is compressed or stretched, it can provide a uniform reaction force to the sleeve 6 and the rubber tube 8, thereby ensuring cleaning efficiency.

[0045] The following is a detailed description of the actual working scenario of a water spray nozzle for cleaning the combustion chamber of an oilfield heating furnace.

[0046] In actual operation, by starting the air pump 2, the air pump 2 can fill the cavity 4 with air through the air inlet 3, making the cavity 4 full of negative pressure. Then, through the air pressure, the groove plate 5 can slide on the outside of the sleeve 6, so that the groove plate 5 can compress the spring 7 outside the sleeve 6. When the groove plate 5 slides to the position of the clamping plate 9, the clamping plate 9 can contact the groove inside the groove plate 5.

[0047] By stopping the air pump 2, the air pressure inside the cavity 4 is dissipated through the air inlet 3, causing the two clamping plates 9 to re-squeeze the rubber tube 8, thereby fixing the rubber tube 8 and preventing water from flowing out.

[0048] When the rubber hose 8 is used to transport water, the rubber hose 8 enters the interior of the water storage tank 14 through the water outlet 11, and then the water flow can drive the nozzle 15 to rotate outside the sealing plate 16, and then the rotating disk 13 can rotate under the pressure of the water flow.

[0049] It is understood that the above-mentioned embodiments mentioned in this utility model can be combined with each other to form combined embodiments without violating the principle and logic. Due to space limitations, this utility model will not elaborate further.

The specific execution order of each step should be determined by its function and possible internal logic.

[0051] The present invention provides a cleaning spray nozzle for the combustion chamber of an oilfield heating furnace. By activating the drive assembly, the air pump can fill the cavity with air through the air inlet, making the cavity filled with negative pressure. Then, through the air pressure, the grooved plate can squeeze the spring outside the sleeve. When the grooved plate slides to the position of the clamping plate, the clamping plate can contact the groove inside the grooved plate.
