Description

Technical Field

[0001] This utility model belongs to the field of cleaning device technology, and in particular relates to a steam boiler inner wall flushing and cleaning device. Background Technology

[0002] A boiler is an energy conversion device. The energy input to a boiler can be in the form of chemical energy from fuel, electrical energy, or thermal energy from high-temperature flue gas. After conversion by the boiler, steam, high-temperature water, or organic heat carriers with a certain amount of thermal energy are output. After a long period of use, the inner wall of the boiler needs to be cleaned to facilitate subsequent use.

[0003] To make cleaning the inner wall of boilers easier, boilers are currently generally cleaned using mechanical equipment. This typically involves a rotating shaft that drives a brush plate to rotate and scrape around the inner wall of the boiler. However, this mechanism currently has some drawbacks in actual use. The distance between the brush plate and the rotating shaft is fixed and cannot be adjusted, making it difficult to clean boilers of different diameters. Furthermore, when encountering smaller boilers, it is difficult to insert or remove the cleaning mechanism from the boiler. Utility Model Content

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0018] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0019] This utility model provides a steam boiler inner wall flushing and cleaning device, such as... Figure 1-3As shown, the system includes a base plate 1, a support base 2 mounted on the upper end of the base plate 1, a bracket 3 mounted on the top of the support base 2, a fixed shaft 5 rotatably mounted on the top of the bracket 3, a motor 6 mounted on the top of the bracket 3, and the bracket 3 extending above the top of the bracket 3. A set of meshing bevel gears 7 are mounted on the output shaft of the motor 6 and the surface of the bracket 3. A first fixing block 8 is mounted below the fixed shaft 5. A first connecting rod 9 is hinged to the side of the first fixing block 8. The other end of the first connecting rod 9 is connected to a connecting plate 10. A sliding groove is formed on the surface of the connecting plate 10, and a slider 11 is slidably connected thereto. The other end of the first connecting rod 9 is hinged to the slider 11. A connecting sleeve 12 is slidably sleeved on the surface of the fixed shaft 5. A second connecting rod 13 is hinged to the side of the connecting sleeve 12. A second fixing block 14 is mounted on the side of the connecting plate 10. The connecting rod 13 is hinged to the second fixing block 14. A brush plate 15 is installed on the outer side of the connecting plate 10. When using this device, the steam boiler to be cleaned can be placed above the bottom plate 1. Then, the motor 6 is started. The motor 6 drives the fixed shaft 5 to rotate through a bevel gear 7. The fixed shaft 5 drives the connecting plate 10 to rotate through the first connecting rod 9 and the second connecting rod 13. At this time, the brush plate 15 on the outer side of the connecting plate 10 scrapes and cleans the inner wall of the boiler. When it is necessary to clean boilers of different diameters, the distance between the brush plate 15 and the fixed shaft 5 can be adjusted by pulling the connecting sleeve 12 up and down. When encountering a boiler with a small opening, the brush plate 15 can be placed close to the fixed shaft 5 and then put in and taken out. This device can adapt to boilers of different sizes by flexibly adjusting the position of the brush plate 15, thereby effectively improving the applicability of the device.

[0020] The bracket 3 is slidably mounted on the top of the support base 2. The support base 2 is equipped with a hydraulic cylinder 4. The output shaft of the hydraulic cylinder 4 is connected to the bracket 3. By setting the left and right hydraulic cylinders 4, after the hydraulic cylinders 4 are started, the fixed shaft 5 is raised or lowered through the bracket 3. This setting makes it easy to put the brush plate 15 into the boiler or take it out of the boiler.

[0021] A water tank cleaning device 16 is installed on the top of the bracket 3. A water pump is installed inside the water tank 16. The water outlet pipe of the water tank 16 is connected to the fixed shaft 5 through a sealed bearing 17. The fixed shaft 5 has a hollow structure inside and a spray nozzle 18 on its surface. With the water tank 16 installed, the water in the water tank 16 is transferred to the fixed shaft 5 by the water pump and sprayed onto the inner wall of the boiler from the spray nozzle 18 on the surface of the fixed shaft 5. This setup can accurately rinse the inner wall of the boiler, thereby improving the cleaning effect of the device.

[0022] A hanger 19 is installed on the top of the connecting sleeve 12. A limiting sleeve 20 is connected to the top of the hanger 19. The limiting sleeve 20 is sleeved on the surface of the fixed shaft 5. A groove is opened on the front side of the limiting sleeve 20, and a pull rod 21 is slidably inserted into the groove. A locking block 22 is connected to the inner end of the pull rod 21, and a spring 23 is sleeved on the outside of the pull rod 21. The surface of the fixed shaft 5 has slots that are adapted to the locking block 22, which are evenly spaced from top to bottom. By setting the limiting sleeve 20, the limiting sleeve 20 is fixed by the cooperation of the spring 23 and the locking block 22. The connecting sleeve 12 is positioned in this way. This fixing method is simple and easy to operate, which improves the convenience of adjusting the brush plate 15. At the same time, placing the limiting sleeve 20 close to the top of the fixed shaft 5 can improve the convenience of operation.

[0023] The outer wall of the connecting plate 10 has a groove. The rear end of the brush plate 15 is inserted into the groove of the outer wall of the connecting plate 10 and is limited by the pin 24. The brush plate 15 is installed on the side of the connecting plate 10 by sliding insertion and is limited by the pin 24. The brush plate 15 is made detachable to facilitate cleaning and replacement later.

[0024] Two sets of brush plates 15 are provided. The two sets of brush plates 15 have the same installation structure and are symmetrically distributed around the fixed axis 5. By setting two sets of brush plates 15, the cleaning can be more efficient and can be closely attached to the inner wall of the boiler to improve the cleaning effect.
