Description

Technical Field

[0001] This utility model relates to the field of steam generator technology, specifically a steam generator with a cleaning structure. Background Technology

[0002] Steam plays an indispensable role as a vital energy medium in numerous fields, including industrial production, energy supply, healthcare, and food processing. As the core equipment for generating steam, the stability and reliability of steam generators directly impact the efficiency and quality of related production processes. Traditional steam generators face several pressing problems during long-term operation. One prominent issue is the accumulation of scale and impurities on the surface of the heating column. During the heating process, calcium and magnesium ions in the water gradually precipitate, forming scale that adheres to the surface of the heating column. This scale has low thermal conductivity, severely hindering heat transfer between the heating column and the water, leading to a significant decrease in heating efficiency. To achieve the same steam output, more electricity is required, increasing production costs.

[0003] The prior art provides a steam generator (publication number: CN222578208U), which includes a housing, an isolation device disposed within the housing and used to divide the inner cavity of the housing into a first cavity and a second cavity, a first heating device disposed within the first cavity, a second heating device disposed within the second cavity, a water inlet pipe connected to the first cavity, and a steam outlet pipe connected to the second cavity and the outside. The first heating device is used to evaporate the liquid in the first cavity, and the second heating device is used to heat the steam entering the second cavity.

[0004] However, the device still has the following drawbacks:

[0005] The device was not cleaned of scale during use. The accumulation of scale caused the local temperature of the heating column to become too high, which accelerated the aging and damage of the heating column, shortened its service life, and increased the maintenance and replacement costs of the equipment. Therefore, we need to propose a steam generator with a cleaning structure. Utility Model Content

[0006] The purpose of this invention is to provide a steam generator with a cleaning structure, which solves the problems mentioned in the background art by providing a cleaning component for cleaning the surface of the electric heating column.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A steam cylinder, the upper end of which is provided with a sealing cover, a fixing rod is fixedly connected inside the steam cylinder, an electric heating column is fixedly connected to the upper end of the fixing rod, the electric heating column is in contact with the sealing cover, and a cleaning component for cleaning the surface of the electric heating column is provided inside the sealing cover.

[0010] The sealing cover is equipped with an anti-dry-burning component to prevent the heating column from burning dry.

[0011] Preferably, the cleaning assembly includes an inlet pipe, a fixed housing, a nozzle, and a water channel;

[0012] The sealing cover has an inlet pipe fixedly connected inside, and a fixed shell is fixedly connected to the lower end of the sealing cover. The fixed shell has multiple nozzles arranged in a ring inside, and a water channel is opened inside the fixed shell.

[0026] 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.

[0027] Please see Figure 1-4 This utility model provides a technical solution:

[0028] A steam generator with a cleaning structure includes:

[0029] A steam cylinder 1 is provided with a sealing cover 2 at its upper end. A fixing rod 4 is fixedly connected inside the steam cylinder 1. An electric heating column 5 is fixedly connected to the upper end of the fixing rod 4. The electric heating column 5 is in contact with the sealing cover 2. A cleaning component 7 for cleaning the surface of the electric heating column 5 is provided inside the sealing cover 2.

[0030] The inside of the sealing cover 2 is equipped with an anti-dry-burning component 8 to prevent the heating column 5 from burning dry.

[0031] For example, the recommended model of the heating column 5 is Watlow. F3A series.

[0032] The cleaning component 7 includes an inlet pipe 71, a fixed housing 72, a nozzle 73, and a water channel 74;

[0033] The sealing cover 2 is fixedly connected to the liquid inlet pipe 71, and the lower end of the sealing cover 2 is fixedly connected to the fixing shell 72. The fixing shell 72 is provided with multiple nozzles 73 arranged in a ring. The fixing shell 72 is provided with a water passage groove 74, which is connected to the liquid inlet pipe 71 and the multiple nozzles 73 respectively.

[0034] For example, the inlet pipe 71 is connected to an external cleaning fluid supply system, and the cleaning fluid supply system can inject the cleaning fluid into the cleaning component 7 with a certain pressure. The lower end of the sealing cover 2 is fixedly connected to the fixing shell 72. The nozzle 73 is connected to the inlet pipe 71 through the water channel 74. When the cleaning fluid enters the water channel 74 inside the fixing shell 72, it will be sprayed out through the nozzle 73 to form a water flow, which will rinse the surface of the electric heating column 5 and clean the scale.

[0035] The anti-dry-burning component 8 includes a lifting rod 81, a float 82, a lifting plate 84, a first control button 85, a guide frame 86, and a second control button 87;

[0036] The sealing cover 2 has a sliding connection to a lifting rod 81, a float plate 82 fixedly connected to the lower end of the lifting rod 81, a sealing ring 83 fixedly connected to the upper end of the sealing cover 2, the sealing ring 83 and the lifting rod 81 being slidably connected, a lifting plate 84 fixedly connected to the upper end of the lifting rod 81, a first control button 85 contacting the lower end of the lifting plate 84, the first control button 85 being fixedly connected to the sealing cover 2, a guide frame 86 slidingly connected inside the lifting plate 84, the guide frame 86 being fixedly connected to the sealing cover 2, and a second control button 87 being provided on the inner top of the guide frame 86.

[0037] For example, the density of the float plate 82 is less than that of water, so it can float on the water surface. The function of the sealing ring 83 is to prevent steam from leaking from the gap between the lifting rod 81 and the sealing cover 2. The lifting plate 84 is used to trigger the control button. When the lifting plate 84 presses the first control button 85, the first control button 85 sends a signal to control the solenoid valve to open and add water to the steam cylinder 1. The function of the guide frame 86 is to limit the movement direction of the lifting plate 84 and ensure that the lifting plate 84 can accurately trigger the control button. The inner top of the guide frame 86 is provided with a second control button 87. When the water level rises, the lifting plate 84 rises to contact the second control button 87. The second control button 87 sends a signal to cut off the solenoid valve, stop adding water, keep the water level within a safe range, and prevent the electric heating column 5 from dry burning.

[0038] A water inlet pipe 3 equipped with a solenoid valve is fixedly connected to the inside of the side wall of the steam cylinder 1. The solenoid valve is electrically connected to the first control button 85 and the second control button 87 respectively.

[0039] For example, when the water level drops to a certain level, the first control button 85 is triggered, the solenoid valve opens, and water enters the steam cylinder 1 through the water inlet pipe 3 to replenish the water level. When the water level returns to normal, the float 82 rises, and the second control button 87 is triggered, the solenoid valve closes, stopping the water intake. This control method can automatically adjust the water intake according to the water level change to ensure that the water level in the steam cylinder 1 is always within a safe range. The recommended model of the solenoid valve is Bürkert 6011 (normally closed type).

[0040] The upper end of the sealing cover 2 is fixedly connected to an exhaust pipe 6 for discharging steam.

[0041] For example, the steam outlet pipe 6 is the steam output channel of the steam generator. When the water in the steam cylinder 1 is heated to boiling by the electric heating column 5 and steam is generated, the steam will be discharged through the steam outlet pipe 6.

[0042] The lower end of the steam cylinder 1 is fixedly connected to a waste liquid pipe 9 for discharging cleaning waste liquid.

[0043] For example, the waste liquid pipe 9 is the discharge channel for the waste liquid generated after the cleaning component 7 cleans the surface of the electric heating column 5. During the cleaning process, the cleaning liquid will mix with the scale and impurities on the surface of the electric heating column 5 to form waste liquid. The waste liquid will accumulate at the bottom of the steam cylinder 1 and be discharged through the waste liquid pipe 9. A valve can be installed on the waste liquid pipe 9 to control the discharge time and flow rate of the waste liquid. After the cleaning is completed, the valve is opened to discharge the waste liquid and ensure the cleanliness of the steam cylinder 1.

[0044] Working principle: When using this utility model, open the water inlet pipe 3 to inject water into the steam cylinder 1, turn on the electric heating column 5, the electric heating column 5 heats the water, and the generated steam is discharged from the steam outlet pipe 6.

[0045] When water is injected, the water causes the float plate 82 to rise, the float plate 82 causes the lifting rod 81 to rise, the lifting rod 81 causes the lifting plate 84 to rise, and when the lifting plate 84 contacts the second control button 87, it controls the solenoid valve on the water inlet pipe 3 to close. Similarly, when water is consumed, the float plate 82 causes the lifting rod 81 and the lifting plate 84 to fall, and when the lifting plate 84 contacts the first control button 85, the first control button 85 controls the solenoid valve on the water inlet pipe 3 to open.

[0046] After a period of use, the cleaning solution (acidic cleaning agent) is injected into the interior of the fixed shell 72 through the liquid inlet pipe 71. The cleaning solution is sprayed onto the surface of the heating column 5 through the nozzle 73 to clean the scale on the surface of the heating column 5. The cleaning solution at the upper end of the heating column 5 slowly descends to clean the surface of the lower end of the heating column 5. After the scale is cleaned, an alkaline liquid is injected through the liquid inlet pipe 71 to neutralize the waste liquid. The waste liquid is discharged from the waste liquid pipe 9. After cleaning, clean water is injected to rinse the surface of the heating column 5 with the cleaning solution.

[0047] The control method of the electric heating column 5, the first control button 85, and the second control button 87 in this application is automatic control by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Furthermore, this application is mainly used to protect the structure, shape, and their combination, so this application will not explain the control method and circuit connection in detail. The device is powered by a built-in power supply or an external power supply.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
