Description

Technical Field

[0001] This utility model relates to the field of boiler scale cleaning, specifically an automatic scale cleaning structure for electric boilers. Background Technology

[0002] An electric boiler is an industrial device that converts electrical energy into heat energy to heat water into pressurized hot water or steam. Typically, as the boiler is used for a longer period of time, varying degrees of scale will accumulate on its inner wall, requiring workers to clean the scale.

[0003] According to publicly available patent CN219414728U, a boiler inner wall scale cleaning device includes a boiler body, a top cover, a lifting ring, a servo motor, and a rotating shaft. The top surface of the boiler body is provided with a top cover, and a lifting ring is fixedly connected to the top surface of the top cover. A servo motor is fixedly connected to the top surface of the top cover, and the extension shaft of the servo motor is fixedly connected to the rotating shaft. A telescopic rod is fixedly connected to the surface of the rotating shaft. This invention solves the problem of low cleaning efficiency of boiler inner wall scale when the boiler has been used for a long time, which affects the actual use effect, by using a telescopic rod and a cleaning roller. By activating the servo motor, the servo motor drives the telescopic rod to rotate, which in turn drives a concave block to rotate, which in turn drives the cleaning roller to rotate, thus cleaning the boiler inner wall and improving work efficiency.

[0004] In the process of developing this utility model, the inventors discovered that at least the following problems remain unresolved in the existing technology: 1. Traditional automatic boiler scale cleaning devices utilize a scraping structure to rub against the inner wall of the boiler to remove scale. However, as cleaning work continues, the scraping structure is prone to wear and tear, requiring replacement. Traditional cleaning structures are inconvenient for operators to replace quickly, making operation difficult. 2. In most automatic boiler scale cleaning devices, due to the large size of the boiler, the inner wall is often quite long, resulting in a correspondingly long scraping structure. This longer scraping structure is more prone to deformation at its end during rotation, leading to torsion and reducing its lifespan and overall strength. Therefore, a new technical solution is needed to address these issues. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an automatic scale removal structure for electric boilers to solve the technical problem that the scraping structure in the current cleaning device is inconvenient to repair and replace.

[0006] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: An automatic scale cleaning structure for an electric boiler is designed, including a motor, a boiler mounted on the side of the motor, an output shaft mounted on the side of the motor, a strip plate mounted on the other end of the output shaft, a fixing rod fixedly connected to the outside of the strip plate, a sleeve sleeved around the outside of the fixing rod, a scraper mounted on the outside of the sleeve, a limiting strip fixedly connected to the side of the scraper, a shaped groove opened inside the sleeve, the limiting strip inserted into the shaped groove, a screw rod at the end of the fixing rod, and a fastening nut connected to the outside of the screw rod by a thread, the fastening nut being pressed against the outside of the limiting strip.

[0007] Preferably, the sleeves are symmetrically distributed, and anti-torsion rings are fixedly connected between the sleeves. Reinforcing rods are fixedly connected between the anti-torsion rings, and there are two reinforcing rods.

[0008] Preferably, a mounting bracket is fixedly connected to the side of the motor, and mounting holes are opened inside the mounting bracket, which is located at the four corners of the motor.

[0009] Preferably, the output shaft is provided with a bearing seat on the outside, the bearing seat is embedded in the side of the boiler, and the output shaft is located inside the boiler.

[0010] Preferably, a threaded rod is fixedly connected to the outside of the output shaft, a slot is opened at the center of the strip plate, a locking block is fixedly connected to the outside of the threaded rod, the locking block is embedded in the inside of the slot, and an anti-loosening nut is connected to the outside of the threaded rod by a thread.

[0011] Preferably, a fixing groove is formed inside the sleeve, and the fixing rod is embedded inside the fixing groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model features a sleeve with an insertable scraper on the outside and a limiting strip at the bottom of the scraper. A groove is formed inside the sleeve to allow for insertion with the limiting strip. A fastening nut is installed on the outside of the screw of the fixing rod. This fastening nut simultaneously tightens and secures the sleeve and the limiting strip. When the worn scraper needs repair or replacement, simply unscrew the fastening nut to remove the scraper and replace it with a new one. The entire process is relatively simple, requiring no disassembly or replacement of other parts of the cleaning structure, facilitating quick repairs and demonstrating strong practicality.

[0014] 2. This utility model adds an anti-torsion ring to the outside of the sleeve and fixes a reinforcing rod between the anti-torsion rings. This can improve the strength between the two sleeves and form a hollow, cylindrical shape between the sleeve and the anti-torsion ring. As the two sleeves rotate, the ends of the sleeves will not easily twist or deform. The anti-torsion ring and the reinforcing rod can effectively improve the connection strength and have strong functionality. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0023] Example 1: An automatic scale removal structure for an electric boiler (see [reference]). Figures 1 to 6The system includes a motor 1, a boiler 20 mounted on the side of the motor 1, an output shaft 4 mounted on the side of the motor 1, a strip plate 9 mounted on the other end of the output shaft 4, a fixing rod 10 fixedly connected to the outside of the strip plate 9, a sleeve 19 sleeved on the outside of the fixing rod 10, and a scraper 13 mounted on the outside of the sleeve 19. Since there are two scraper 13s, the scraping operation inside the boiler 20 can be accelerated. A limiting strip 14 is fixedly connected to the side of the scraper 13. A groove 15 is formed inside the sleeve 19, and the limiting strip 14 is inserted into the groove 15. A screw 11 is provided at the end of the fixing rod 10, and a fastening nut 12 is threadedly connected to the outside of the screw 11, pressing the fastening nut 12 against the limiting strip 1. Externally, a sleeve 19 is provided, and an insertable scraper 13 is provided on the outside of the sleeve 19. A limiting strip 14 is installed at the bottom of the scraper 13. An irregular groove 15 is opened inside the sleeve 19 to connect with the limiting strip 14 for insertion. At the same time, a fastening nut 12 is installed on the outside of the screw 11 of the fixing rod 10. This fastening nut 12 can simultaneously press and fix the sleeve 19 and the limiting strip 14. When it is necessary to repair or replace the worn scraper 13, simply unscrew the fastening nut 12, and the scraper 13 can be pulled out and replaced with a new scraper 13 structure. The whole process is relatively easy to operate.

[0024] For details, see Figures 1 to 6 The sleeves 19 are symmetrically distributed, and anti-torsion rings 16 are fixedly connected between the sleeves 19. Reinforcing rods 18 are fixedly connected between the anti-torsion rings 16. There are two reinforcing rods 18. Since anti-torsion rings 16 are added to the outside of the sleeves 19 and reinforcing rods 18 are fixedly connected between the anti-torsion rings 16, the strength between the two sleeves 19 can be improved, so that a hollow, cylindrical shape can be formed between the sleeves 19 and the anti-torsion rings 16. In this way, as the two sleeves 19 rotate, the ends of the sleeves 19 will not easily twist or deform. The anti-torsion rings 16 and reinforcing rods 18 can effectively improve the connection strength.

[0025] Further, see Figures 1 to 6 The mounting bracket 2 is fixedly connected to the side of the motor 1. The mounting bracket 2 has mounting holes inside. The mounting bracket 2 is located at the four corners of the motor 1. When installing this cleaning structure, you only need to attach the mounting bracket 2 to the side of the boiler 20 and then install the fasteners to complete the installation. The whole installation process is relatively simple and convenient.

[0026] It is worth noting that, see Figures 1 to 6 The output shaft 4 is provided with a bearing seat 3 on the outside, which is embedded in the side of the boiler 20. The output shaft 4 is located inside the boiler 20. Due to the bearing seat 3, the stability of the output shaft 4 can be improved during operation.

[0027] It is worth noting that, see Figures 1 to 6 The output shaft 4 is externally fixedly connected to a threaded rod 5. A slot 8 is opened at the center of the strip plate 9. The threaded rod 5 is externally fixedly connected to a locking block 7, which is embedded in the slot 8. The threaded rod 5 is externally connected to an anti-loosening nut 6 via a thread. Since the locking block 7 is embedded in the strip plate 9 on the output shaft 4, when installing or removing the strip plate 9, it is only necessary to unscrew the anti-loosening nut 6 and then pull out the strip plate 9 to complete the disassembly work, which is simple and convenient to operate.

[0028] It is worth mentioning that, see Figures 1 to 6 The sleeve 19 has a fixing groove 17 inside, and the fixing rod 10 is embedded in the fixing groove 17. Since the sleeve 19 is fitted onto the fixing rod 10, it is convenient for workers to assemble it, and it is highly practical.

[0029] When using the automatic scale removal structure, since the entire structure is located inside the boiler 20, and the motor 1, a component of it, is located at one end of the boiler 20, operation only requires starting the motor 1 to drive the output shaft 4 to rotate. Simultaneously, the output shaft 4 drives the strip plate 9 and its surface sleeve 19 to rotate. At this time, the scraper 13 located outside the sleeve 19 can move along the inner wall of the boiler 20. Because the scraper 13 makes a circular motion, the scale adhering to the inner wall of the boiler 20 will be cleaned away by the scraper 13, thus achieving... The automatic cleaning effect is achieved. During the operation of this cleaning structure, an anti-torsion ring 16 is added to the outside of the sleeve 19, and a reinforcing rod 18 is fixedly connected between the anti-torsion rings 16. This increases the strength between the two sleeves 19, allowing a hollow, cylindrical shape to be formed between the sleeves 19 and the anti-torsion rings 16. Thus, as the two sleeves 19 rotate, the ends of the sleeves 19 will not easily twist or deform. The anti-torsion rings 16 and the reinforcing rods 18 effectively improve the connection strength. The cleaning structure has strong functionality. However, as the cleaning structure is used for a longer period, when the scraper 13 wears down, leading to a decrease in cleaning effectiveness, the cleaning structure inside the boiler 20 can be opened to replace the scraper 13. This is achieved by installing a sleeve 19 on the outside of the fixing rod 10, with a plug-in scraper 13 on the outside of the sleeve 19, and a limiting strip 14 installed at the bottom of the scraper 13. A groove 15 is formed inside the sleeve 19 to allow for plug-in installation with the limiting strip 14. Simultaneously, the fixing rod 10... A fastening nut 12 is installed on the outside of the screw 11. This fastening nut 12 can simultaneously tighten and fix the sleeve 19 and the limiting strip 14. When starting maintenance and replacement, simply unscrew the fastening nut 12, and then the scraper 13 can be pulled out separately. Then, take out the new scraper 13 and insert it back into the irregular groove 15 to complete the replacement of the scraper 13. The whole process is easy to operate and does not require disassembly or replacement of other parts of the cleaning structure, which facilitates quick maintenance by the staff and is highly practical.
