Description

Technical Field

[0001] This utility model relates to the field of industrial water heater technology, specifically to a self-cleaning mechanism for an industrial water heater. Background Technology

[0002] With the rapid development of the clean energy industry, photovoltaic manufacturing, as a key link, places higher demands on the stability, cleanliness, and energy efficiency of auxiliary equipment in the production process. Industrial hot water heaters are widely used in processes such as silicon wafer cleaning, pure water preheating, and equipment insulation in the photovoltaic industry. Their core function is to provide high-temperature hot water with stable temperature and clean quality. However, during long-term continuous operation, the inside of the water tank of industrial hot water heaters, especially the bottom area, is prone to particulate matter sedimentation due to trace impurities in the water, the precipitation of metal ions, or the deposition of corrosion products from pipes.

[0003] These deposits typically include calcium carbonate, metal oxides, silicate particles, and suspended solids from the water supply system. Because traditional industrial hot water heaters often have closed tank structures and lack effective self-cleaning mechanisms, once particulate matter settles to the bottom of the tank, it is difficult to completely remove it through conventional drainage methods. Over time, the deposit layer thickens, not only reducing the effective volume and heat exchange efficiency of the tank but also potentially becoming a breeding ground for microorganisms, thus contaminating the hot water. In applications such as photovoltaic manufacturing, where extremely high water purity is required, this type of contamination directly affects the cleaning effect on silicon wafer surfaces, leading to decreased cell conversion efficiency or even product failure.

[0004] Furthermore, while some existing water heaters are equipped with drain outlets, they can only discharge a portion of suspended solids, offering limited effectiveness in cleaning sediment adhering to the bottom of the tank or accumulating in clumps. Thorough cleaning often requires stopping the machine, disassembling the tank, and manual rinsing, which is not only cumbersome and time-consuming but also disrupts the production line, impacting overall capacity.

[0005] Therefore, it is necessary to provide a self-cleaning mechanism for industrial water heaters to solve the above problems. Utility Model Content

[0006] Based on the aforementioned problems in the existing technology, the purpose of this utility model is to provide a self-cleaning mechanism for an industrial water heater to solve the problems mentioned in the background technology.

[0007] The technical solution adopted by this utility model to solve its technical problem is: a self-cleaning mechanism for an industrial hot water machine, including a water storage tank with a receiving cavity, the water storage tank having an inlet pipe, an outlet pipe and a waste discharge pipe communicating with the receiving cavity, the bottom of the receiving cavity having a receiving surface, a discharge surface and a platform surface, the discharge surface and the platform surface being located on one side of the receiving surface, and the waste discharge pipe being located above the platform surface; The cavity also contains a scraper unit that scrapes the receiving surface.

[0008] Furthermore, the inner wall of the receiving cavity is provided with grooves on both sides along the long side direction; The scraper unit includes a connecting rod and a silicone plate, the silicone plate being located below the connecting rod, and both ends of the connecting rod being located within a groove; The bottom edge of the silicone plate extends to the surface of the receiving surface.

[0009] Furthermore, it also includes a linear push rod, one end of which is sealed to the water tank. The linear push rod has a telescopic primary push rod and a secondary push rod inside. The secondary push rod is located outside the primary push rod, and the end of the secondary push rod is fixedly connected to the connecting rod.

[0010] Furthermore, the scraper unit also includes an arc-shaped guide plate located above the connecting rod, the guide plate having a filter screen.

[0011] Furthermore, the inlet pipe and outlet pipe are located on opposite sides of the water storage tank, and the waste discharge pipe is located on the same side as the inlet pipe and below the inlet pipe.

[0012] Furthermore, the upper surface of the receiving surface gradually decreases in height from the side closer to the water outlet pipe to the side farther away from the water outlet pipe, and the upper surface of the discharge surface gradually decreases from the end farther away from the platform surface to the side closer to the platform surface, and the upper surface of the platform surface is a plane.

[0013] The beneficial effects of this utility model are as follows: The self-cleaning mechanism of the industrial water heater provided by this utility model, by setting the bottom of the receiving cavity with staggered slopes, causes particles to roll down along the slopes to the position closest to the waste discharge pipe. The scraper unit scrapes off the particles that remain on the receiving surface, which improves the efficiency of the mechanism in cleaning particles and prevents particles from accumulating at the bottom of the water tank. It solves the technical problem that although most industrial water heaters are equipped with basic drain valves or manual cleaning ports, they are limited by structural design and it is difficult to thoroughly clean the dead corner area at the bottom of the water tank. By incorporating a baffle plate, particles floating at the bottom can be intercepted as the scraper unit moves, preventing them from scattering throughout the containment cavity.

[0014] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The present utility model will now be described in further detail with reference to the figures. Attached Figure Description

[0016] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0018] like Figure 1-6 As shown, the present invention provides a technical solution: a self-cleaning mechanism for an industrial hot water machine, including a water storage tank 1 with a receiving cavity 101, an inlet pipe 2, an outlet pipe 3 and a waste discharge pipe 4 communicating with the receiving cavity 101, the bottom of the receiving cavity 101 having a receiving surface 102, a discharge surface 103 and a platform surface 104, the discharge surface 103 and the platform surface 104 being located on one side of the receiving surface 102, and the waste discharge pipe 4 being located above the platform surface 104; A scraper unit 6 for scraping the receiving surface 102 is also slidably connected inside the receiving cavity 101.

[0019] The inner wall of the receiving cavity 101 is provided with grooves 11 on both sides along the long side; The scraper unit 6 includes a connecting rod 61 and a silicone plate 63. The silicone plate 63 is located below the connecting rod 61, and both ends of the connecting rod 61 are located in the groove 11. The bottom edge of the silicone plate 63 extends to the surface of the receiving surface 102.

[0020] It also includes a linear push rod 5, one end of which is sealed to the water tank 1. The linear push rod 5 has a telescopic primary push rod 51 and a secondary push rod 52 inside. The secondary push rod 52 is located outside the primary push rod 51, and the end of the secondary push rod 52 is fixedly connected to the connecting rod 61.

[0021] The scraper unit 6 also includes an arc-shaped guide plate 62 located above the connecting rod 61, and the guide plate 62 has a filter screen.

[0022] The inlet pipe 2 and outlet pipe 3 are located on opposite sides of the water storage tank 1, and the waste discharge pipe 4 is located on the same side as the inlet pipe 2 and below it. This arrangement keeps the waste discharge pipe 4 away from the outlet pipe 3, preventing the outlet pipe 3 from interfering with the waste discharge pipe 4, and allowing particulate matter to be discharged from the waste discharge pipe 4.

[0023] The height of the upper surface of the receiving surface 102 gradually decreases from the side closer to the water outlet pipe 3 to the side farther away from the water outlet pipe 3, and the upper surface of the discharge surface 103 gradually decreases from the end farther away from the platform surface 104 to the side closer to the platform surface 104. The upper surface of the platform surface 104 is a plane.

[0024] In one embodiment, this organization performs descaling operations.

[0025] Specifically, water enters the water storage tank 1 from the inlet pipe 2 and is discharged from the outlet pipe 3. The water is concentrated in the receiving cavity 101. The particles in the water fall onto the receiving surface 102 under the influence of gravity. Some of the larger particles fall onto the discharge surface 103 along the slope of the receiving surface 102. At this time, there are still smaller particles attached to the discharge surface 103. When the linear push rod 5 is activated, the linear push rod 5 extends the first-stage push rod 51 and the second-stage push rod 52 in sequence, which drives the connecting rod 61 to move along the slide groove 11. At this time, the silicone plate 63 moves along the upper surface of the receiving surface 102 towards the discharge surface 103. The silicone plate 63 scrapes the small particles on the receiving surface 102 into the discharge surface 103, and the guide plate 62 can prevent the particles from floating up. When the silicone plate 63 reaches the discharge surface 103, the particles are attached to the discharge surface 103 and the platform surface 104. At this time, the water pump of the waste discharge pipe 4 is turned on. Affected by the water flow, the particles adsorbed on the discharge surface 103 and the platform surface 104 are extracted from the receiving cavity 101 along the waste discharge pipe 4.

[0026] In summary, by setting the bottom of the receiving cavity 101 with staggered slopes, the particles can roll down the slopes to the position closest to the waste discharge pipe 4. The scraper unit 6 scrapes off the particles remaining on the receiving surface 103, and the cleaning can be completed without stopping the machine. This improves the efficiency of the mechanism in cleaning particles, prevents particles from accumulating at the bottom of the water tank 1, and solves the technical problem that thoroughly cleaning the receiving cavity 101 often requires stopping the machine, disassembling the tank and manually rinsing, which is not only cumbersome and time-consuming, but also causes production line interruption and affects the overall production capacity. By providing the guide plate 62, the particles floating at the bottom can be intercepted when the scraper unit 6 moves, preventing the particles from drifting around in the receiving cavity 101.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
