[0002] A furnace soot blower, also called a furnace soot blowing device or soot blower, is a piece of equipment used in a boiler combustion system. Its main function is to periodically clean the ash and slag inside the furnace to prevent the accumulation of ash and slag from affecting combustion efficiency and normal boiler operation.

[0003] Some existing traditional short telescopic furnace sootblowers use a threaded connection to fix the nozzle to the spiral gun barrel. After a period of use, the nozzle will be damaged, which will affect the normal operation of the sootblower. At this time, the nozzle needs to be replaced. However, during use, clumps are easily formed at the connection between the nozzle and the threaded gun barrel, making it difficult to manually disassemble the nozzle connection. Tools are required, making the disassembly and assembly operation time-consuming, laborious, and impractical. Therefore, a new type of furnace sootblower is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a new type of furnace soot blower, which aims to improve the problem that in the prior art, the nozzle of the short telescopic furnace soot blower is prone to forming clumps at the connection between the nozzle and the threaded gun barrel during use. This makes it difficult to manually disassemble the nozzle connection and requires the use of tools, resulting in a time-consuming and laborious disassembly and assembly operation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel furnace soot blower, comprising a shell, characterized in that: a threaded gun barrel is provided in the middle of the shell, a soot blowing assembly is provided at the front of the threaded gun barrel, a wall box is provided at the front of the shell, a front support is provided at the front of the shell, a gear is provided in the middle of the front support, a gooseneck valve is provided at the lower part of the shell, and a reduction motor is installed at the rear of the shell; the soot blowing assembly includes a nozzle, a nozzle head is rotatably connected to the front of the nozzle, cleaning rods are fixedly connected to the upper and lower parts of the outer wall of the nozzle, two air passages are opened in the middle of the nozzle, nozzles are opened at the upper and lower parts of the outer wall of the nozzle, the nozzles are connected to the air passages, a connecting cavity is opened on the side of the air passage near the nozzle, the connecting cavity is connected to the nozzle, and multiple cleaning protrusions are fixedly connected to the inner wall of the cleaning rod.

[0006] As a further description of the above technical solution: The two airways are arranged in opposition.

[0007] As a further description of the above technical solution: The airway is designed to be arc-shaped.

[0008] As a further description of the above technical solution: The rear end of the cleaning rod is provided with an arc surface.

[0009] As a further description of the above technical solution: The front of the threaded gun barrel is fixedly connected to a mounting base, and the front of the mounting base is fixedly connected to a threaded tube. The nozzle is threadedly connected to the threaded tube.

[0010] As a further description of the above technical solution: The front side of the threaded gun barrel is provided with an annular groove, and the rear part of the cleaning rod is movably connected to the annular groove. The inner wall of the annular groove is adapted to the arc surface.

[0011] As a further description of the above technical solution: A gas supply pipe is provided in the middle of the threaded gun barrel, and the two ends of the gas supply pipe are respectively connected to the gooseneck valve and the threaded gun barrel.

[0012] This utility model has the following beneficial effects: 1.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figures 1-2 This utility model provides an embodiment of a novel furnace sootblower, comprising a housing 1, which is a short telescopic furnace sootblower housing used to connect various components. A threaded gun barrel 3 is provided in the middle of the housing 1 for sootblowing operations inside the furnace. A guide rod adapted to the housing 1 is provided inside the housing 1. A sootblowing assembly 7 is provided at the front of the threaded gun barrel 3. A wall box 2 is provided at the front of the housing 1 for installation of the sootblower. A front bracket 6 is provided at the front of the housing 1 for connecting various components. A gear is provided in the middle of the front bracket 6. A gooseneck valve 4 is provided at the lower part of the housing 1 for connection with a gas supply device. An air supply pipe 41 is provided in the middle of the threaded gun barrel 3 for supplying air to the gooseneck valve 4. 41 is connected to the gooseneck valve 4 and the threaded gun barrel 3 at both ends respectively. A reduction motor 5 is installed at the rear of the outer casing 1, which is used to drive the gear in the front bracket 6. The gear is used to drive the threaded gun barrel 3 and the cam set at its rear to move forward along the guide rod. The cam has a guide groove. The threaded gun barrel 3 and the cam rotate in the same direction. The stroke of the threaded gun barrel 3 is predetermined. It can drive the nozzle 72 to move to the set position and perform soot blowing operation by steam. Except for the soot blowing assembly 7 and the structure set at the front of the threaded gun barrel 3, all the above components are the original structure of the short telescopic furnace soot blower. The specific internal component structure and connection and operation relationship of the short telescopic furnace soot blower are determined according to the production situation of the specific equipment. Only a brief description is given here.

[0018] like Figures 3-4As shown, the soot blowing assembly 7 includes a nozzle 71 for conveying steam. A nozzle 72 is rotatably connected to the front of the nozzle 71 for ejecting steam. Cleaning rods 73 are fixedly connected to the upper and lower parts of the outer wall of the nozzle 72 for cleaning the connection between the nozzle 71 and the mounting base 32. Two air passages 722 are provided in the middle of the nozzle 72. The two air passages 722 are arranged opposite each other and are arc-shaped. Nozzles 721 are provided on the upper and lower parts of the outer wall of the nozzle 72. The nozzles 721 are connected to the air passages 722 for ejecting steam. A connecting cavity 723 is provided on the side of the air passage 722 near the nozzle 71. The connecting cavity 723 is connected to the nozzle 71. The flow of steam can drive the nozzle 72 to rotate through the connecting cavity 723, the air passage 722 and the nozzle 721.

[0019] Please see Figures 5-6 The inner wall of the cleaning rod 73 is fixedly connected with multiple cleaning protrusions 731, which are closely attached to the outer surface of the connection between the nozzle 71 and the mounting base 32 to clean the clumps there. The rear end of the cleaning rod 73 is provided with an arc surface 732 to reduce the friction during rotation.

[0020] Furthermore, a mounting base 32 is fixedly connected to the front of the threaded gun barrel 3, which is used to connect various components. A threaded tube 33 is fixedly connected to the front of the mounting base 32, which is used to connect the nozzle 71. The nozzle 71 is threadedly connected to the threaded tube 33. An annular groove 31 is opened on the front side of the threaded gun barrel 3. The rear of the cleaning rod 73 is movably connected to the annular groove 31. The annular groove 31 can prevent the rear of the cleaning rod 73 from lifting or vibrating due to lumps and protrusions. The inner wall of the annular groove 31 is adapted to the arc surface 732 to reduce the friction when the cleaning rod 73 rotates.

[0021] Working principle: During use, the motor drives the gear inside the front bracket 6, which in turn drives the threaded gun barrel 3 and the cam at its rear to move forward along the guide rod. The threaded gun barrel 3 and the cam rotate in the same direction. When the cam rotates to a certain angle, the guide groove on the cam guides the rear pawl and the guide rod, so that the cam and the threaded gun barrel 3 stop rotating and move along the guide rod. The nozzle and the threaded gun barrel 3 will extend into the furnace. When the threaded gun barrel 3 of the soot blower extends to the front limit position, the cam will disengage from the guide rod, driving the threaded gun barrel 3 and the soot blowing assembly 7 at its front to rotate together with the gear. Then the cam will open the valve to perform soot blowing operation in the furnace.

[0022] The cleaning steam is delivered into the gas supply pipe 41 through the gooseneck valve 4, then from the gas supply pipe 41 to the threaded gun barrel 3, and finally out through the nozzle 72 installed at the front of the threaded gun barrel 3. The steam ejected from the nozzle 72 will perform soot blowing in the furnace. After the steam enters the soot blowing assembly 7 from the threaded gun barrel 3, the airflow will be delivered to the nozzle 72 through the nozzle 71. When the steam flows in the nozzle 71, the steam will enter the air passage 722 through the connecting cavity 723, and the airflow will pass through the arc-shaped air passage 722. The joint 72 will rotate accordingly, and the steam will be sent out through the nozzle 721 to achieve the soot blowing operation. When the nozzle 72 rotates, the cleaning rod 73 fixed to the nozzle 72 will be driven to rotate as well. At this time, the rear part of the cleaning rod 73 will rotate in the annular groove 31, and the cleaning protrusions 731 on the inner wall of the cleaning rod 73 will clean the connection between the nozzle 71 and the mounting base 32 to prevent the nozzle 71 from being difficult to detach from the mounting base 32 due to the formation of clumps.

[0023] Once the predetermined number of soot blowing cycles is completed, the motor will drive the threaded gun barrel 3, the soot blowing assembly 7, and the cam to rotate in reverse simultaneously, at which point the valve will close and soot blowing will stop.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
