Description

Technical Field

[0001] This utility model relates to the field of surface spraying equipment, specifically a biomass furnace surface spraying device. Background Technology

[0002] After the biomass furnace is processed, it needs to be coated with anti-rust paint. The anti-rust paint effectively prevents the furnace surface from rusting. When coating the biomass furnace surface, it is necessary to use a spraying equipment to spray evenly. Existing spraying equipment sprays through a single nozzle at a single location, which is slow and cannot achieve effective and even coating.

[0003] According to patent document CN220215377U, a positioning device for metal surface spraying includes a base plate. Vertical plates one and two are welded to both ends of the upper surface of the base plate. A rotatable rotating rod is inserted into vertical plate one, and a frame is fixed to the inner end of the rotating rod one. Two sliding plates that can slide up and down along the frame are provided on the frame, and threaded rods are inserted into the sliding plates. The rotating rod two is connected to the inner side of vertical plate two via a bearing. In use, this technical solution uses a rotatable frame on the inner side of vertical plate one, and a sliding threaded rod on the frame. The threaded rod, in conjunction with an extrusion frame on an extrusion plate, extrudes and fixes the metal sheet, thereby positioning and fixing the metal sheet. However, while this solution achieves the positioning and fixing of the metal sheet, it cannot quickly dry the sprayed sheet during use, causing inconvenience. Utility Model Content

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figures 1 to 6This utility model provides a technical solution: a biomass furnace surface spraying device, including a base 1, a support frame 3 welded on the base 1, a fixed plate 6 fixed on the support frame 3, an injection pipe 7 fixedly installed between the fixed plate 6 and the support frame 3, a ring seat 8 movably installed at the bottom of the ring seat 8, a drive motor 9 fixed between the support frames 3, an output shaft 10 installed on the drive motor 9, a fixed column 11 welded on the output shaft 10, one end of the fixed column 11 welded to the inner wall of the ring seat 8, a support pipe 12 welded to the bottom of the ring seat 8, a support plate 14 welded to the side of the support pipe 12, a fixed pipe 15 fixed to the inner wall of the support pipe 12, a nozzle 16 movably installed on the fixed pipe 15, the nozzle 16 movably installed between the support plates 14, a fixing block 2 welded to the side of the base 1, the fixing block 2 fixes the base 1 to the ground, and the nozzle 16 installed between the support plates 14 effectively avoids damage to the nozzle 16 caused by external collision force.

[0026] In this embodiment, a cleaning seat 13 is rotatably mounted on the bottom of the support tube 12. The cleaning seat 13 is rotatably mounted on the bottom of the support tube 12 via a threaded tube. A movable seat 4 is movably mounted between the bases 1. A DC motor 20 is fixedly mounted inside the movable seat 4. An mounting base 5 is mounted on the DC motor 20. A furnace body is placed on the mounting base 5. A displacement mechanism 18 is fixed on the side of the base 1. A movable column 19 is mounted on the displacement mechanism 18. The movable seat 4 has a positioning hole and a mounting hole inside. The displacement mechanism 18 is movably mounted inside the mounting hole. A positioning column 17 is movably mounted inside the positioning hole. One end of the positioning column 17 is fixed to the base 1. The positioning column 17 and the displacement mechanism 18 cooperate to ensure the horizontal movement of the movable seat 4. The displacement mechanism 18 is a linear reciprocating electric push rod, which provides the necessary power for the movement of the movable seat 4.

[0027] In this embodiment, a movable tube 22 is fixed on the nozzle 16, and an atomizing nozzle 21 is opened between the movable tube 22 and the nozzle 16. A threaded seat 23 and a piston seat 24 are fixed on the movable tube 22 respectively. The threaded seat 23 and the piston seat 24 are movably installed inside the fixed tube 15. A connecting seat 25 is welded on the fixed plate 6. An annular groove 26 is opened on the connecting seat 25. A sealing ring 27 is movably installed inside the annular groove 26. The sealing ring 27 is fixed on the inner wall of the annular seat 8. The threaded seat 23 drives the piston seat 24 to rotate inside the fixed tube 15. After rotating to adjust the position of the nozzle 16, the piston seat 24 completes the sealing, allowing the material to be sprayed out from the atomizing nozzle 16.

[0028] Working principle: When using this device, the drive motor 9 is started to drive the output shaft 10 to rotate. The rotation of the output shaft 10 drives the ring seat 8 to rotate through the fixed column 11. After the ring seat 8 rotates, the support tube 12 moves to the side of the support frame 3. The displacement mechanism 18 is started to push the movable seat 4 to move outward. The bottom of the movable seat 4 is fixed with moving wheels to facilitate the overall movement of the movable seat 4 later. After the movable seat 4 is moved out, one end of the circular furnace body is placed on the mounting base 5. The displacement mechanism 18 is started to retract inward. When the movable seat 4 retracts inward, the furnace body needs to be manually moved inward. After the movable seat 4 returns to its position, paint is supplied to the inside of the injection pipe 7 through the external paint supply device. Oil and gas enter the inside of the ring seat 8, and the gas moves downward through the support tube 12. Before painting, the distance between the spray points needs to be adjusted according to the shape of the furnace body. The spray head 16 is rotated inside the fixed tube 15. As the spray head 16 rotates, the threaded seat 23 drives the movable tube 22 to move inward and outward, moving the position of the atomizing spray hole 21, so as to better paint the furnace body. During painting, the drive motor 9 drives the ring seat 8 to rotate slowly, and the atomizing spray hole 21 sprays paint onto the furnace body. The positions of the atomizing spray hole 21 are opposite in two positions, and the spray head 16 at the opposite points is staggered vertically, so as to complete the rapid painting of different positions of the furnace body. After the painting is completed, the paint supply is turned off, and the drive motor 9 is started to rotate at high speed. The drive motor 9 drives the support plate 14 to rotate, driving the airflow to dry the surface of the furnace body, effectively speeding up the work efficiency.
