Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrode hot water boiler technology, and in particular to a phase change heat transfer submerged electrode hot water boiler. Background Technology
[0002] With the continuous development of society, in recent years, people have had increasingly higher requirements for heating and a greater pursuit of energy efficiency. Submersible electric hot water boilers have been widely used in industrial production, commercial building heating, and domestic hot water supply due to their clean, non-combustible, and highly efficient characteristics. Their working principle is mainly based on the conductivity of water to achieve heating. Electrodes are directly immersed in water. When a power source is connected to the electrodes, current flows from the electrodes into the water. Since water itself has a certain resistance, when the current passes through the water, electrical energy is converted into heat energy, thereby raising the water temperature.
[0003] Since submerged electrode hot water boilers mainly utilize the resistance of water for heating, they have high requirements for water quality. Scale formed by calcium and magnesium ions in the water will reduce heat transfer efficiency, increase energy consumption, and may also cause electrode corrosion. Filter plates are usually installed, but existing hot water boilers may not be able to replace the filter plates quickly, which will affect the work efficiency of the staff to some extent. At the same time, the water level inside the boiler may change, while the heating electrode position is usually fixed, which may lead to dry burning, affecting heating efficiency and even causing safety accidents. Utility Model Content
[0004] The purpose of this invention is to provide a phase-change heat exchange submerged electrode hot water boiler, which allows workers to quickly replace filter plates, improving their work efficiency. At the same time, it allows the heating electrodes to adjust their height according to the water level, improving their heating efficiency and reducing the probability of safety accidents.
[0005] To achieve the above objectives, a phase-change heat exchange submerged electrode hot water boiler is provided, comprising a furnace body, a top cover at the upper end of the furnace body, a first pipe fixedly connected to the upper surface of the top cover, a second pipe fixedly connected to the upper surface of the first pipe, a filter plate movably placed inside the first pipe, a fixing plate fixedly connected to the upper surface of the top cover, a support shaft provided inside the furnace body and the top cover, and a sleeve rotatably sleeved on the upper outer surface of the support shaft.
[0006] According to the aforementioned phase change heat transfer submerged electrode hot water boiler, a sliding cylinder is fixedly connected to the outer surface of the sleeve, a toggle plate is fixedly connected to the upper surface of the sliding cylinder, a sliding rod is slidably connected to the inside of the sliding cylinder, a limit rod is fixedly connected to the outer surface of the sliding rod, a groove is opened on the outer surface of the fixed plate, a second hole is opened inside the groove, and the inside of the second hole and the outer surface of the limit rod are movably sleeved.
[0007] According to the aforementioned phase change heat transfer submerged electrode hot water boiler, a support plate is fixedly connected to the outer surface of the first pipe, and a first hole is opened inside the support plate. A limit box is fixedly connected to the upper surface of the filter plate, and a spring is provided inside the limit box. Sliding plates are fixedly connected to both ends of the spring, and a locking rod is fixedly connected to the outer surface of the sliding plate. The outer surface of the locking rod is movably connected to the inside of the first hole.
[0008] According to the aforementioned submerged electrode hot water boiler with phase change heat transfer, the bottom surface of the boiler body is fixedly connected to a support leg, and the bottom surface of the support leg is fixedly connected to a rubber pad.
[0009] According to the aforementioned submerged electrode hot water boiler with phase change heat transfer, the outer surface of the boiler body is fixedly connected with lifting lugs, and the outer surface of the lifting lugs is rounded.
[0010] According to the aforementioned submerged electrode hot water boiler with phase change heat transfer, a water outlet pipe is fixedly connected to the bottom surface of the boiler body, and an air outlet is fixedly connected to the upper surface of the top cover.
[0011] According to the phase change heat transfer submerged electrode hot water boiler, a support frame is fixedly connected to the bottom end of the support shaft, and a heating electrode is fixedly connected to the bottom surface of the support frame.
[0012] According to the aforementioned submerged electrode hot water boiler with phase change heat transfer, a first limiting plate is fixedly connected to the top of the support shaft, and a second limiting plate is fixedly connected to the outer surface of the support shaft.
[0013] Beneficial effects:
[0014] 1. The operator holds the top of the two sliding plates with one hand and compresses the spring, causing the two sliding plates to slide the locking rod inside the limiting box until the locking rod is completely disengaged from the first hole. At the same time, the other hand pulls the filter plate inside the first pipe outward. When a new filter plate needs to be inserted, the operator first holds the top of the two sliding plates to compress the spring, then pushes the filter plate into the first pipe. After the filter plate is fully inside the first pipe, the operator releases the two sliding plates. The release of the spring force will push the sliding plates to slide the locking rod outward, allowing the locking rod to enter the first hole. This allows the filter plate and support plate to be quickly pulled out and locked, enabling the operator to quickly install and replace the filter plate, reducing the difficulty of operation and improving the operator's work efficiency to a certain extent.
[0015] 2. When the water level inside the furnace needs to be changed, the operator needs to pull the actuating plate to make the sliding cylinder rotate around the support shaft, thereby causing the sliding rod and the limiting rod to completely disengage from the support shaft. Then, the sliding rod is slid to the desired position. At this time, the actuating plate is pulled again to make the sliding cylinder rotate around the support shaft, so that the limiting rod on the outer surface of the sliding rod completely enters the interior of the support shaft. This achieves the purpose of moving the position of the heating electrode inside the furnace, allowing the operator to reasonably control the position of the heating electrode according to different water levels, reducing the probability of dry burning, improving the heating efficiency of the electrode hot water boiler to a certain extent, and reducing the probability of safety accidents.

[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0025] Reference Figure 1-4 This utility model discloses a phase-change heat transfer submerged electrode hot water boiler, which includes a furnace body 1, a top cover 11 at the upper end of the furnace body 1, a first pipe 2 fixedly connected to the upper surface of the top cover 11, a second pipe 10 fixedly connected to the upper surface of the first pipe 2, a filter plate 3 movably placed inside the first pipe 2, a fixing plate 19 fixedly connected to the upper surface of the top cover 11, a support shaft 12 provided inside the furnace body 1 and the top cover 11, and a sleeve 13 rotatably sleeved on the upper outer surface of the support shaft 12.
[0026] Specifically: Through the cooperation of the top cover 11, the first pipe 2, and the filter plate 3, the furnace body 1 can filter water and reduce impurities entering the furnace body. At the same time, the cooperation between the fixed plate 19, the support shaft 12, and the sleeve 13 allows the support shaft 12 to move up and down.
[0027] A slide cylinder 28 is fixedly connected to the outer surface of the sleeve 13. A toggle plate 16 is fixedly connected to the upper surface of the slide cylinder 28. A slide rod 17 is slidably connected inside the slide cylinder 28. A limit rod 18 is fixedly connected to the outer surface of the slide rod 17. A slot 20 is opened on the outer surface of the fixed plate 19. A second hole 21 is opened inside the slot 20. The inside of the second hole 21 is movably connected to the outer surface of the limit rod 18.
[0028] Specifically: Due to the design of the actuating plate 16 on the upper surface of the slide cylinder 28, it is easier for the operator to grip the slide cylinder 28 when rotating it. Through the movable cooperation of the limiting rod 18 on the outer surface of the sliding rod 17 and the groove 20 on the outer surface of the fixing plate 19, the up and down positions of the sliding rod 17 and the slide cylinder 28 can be controlled.
[0029] A support plate 4 is fixedly connected to the outer surface of the first pipe 2. A first hole 5 is opened inside the support plate 4. A limit box 6 is fixedly connected to the upper surface of the filter plate 3. A spring 7 is installed inside the limit box 6. Sliding plates 8 are fixedly connected to both ends of the spring 7. A locking rod 9 is fixedly connected to the outer surface of the sliding plate 8. The outer surface of the locking rod 9 is movably connected to the inside of the first hole 5.
[0030] Specifically: the spring 7 inside the limiting box 6 can push the sliding plate 8 and the locking rod 9 to slide through elastic contraction and elastic expansion, so that the outer end of the locking rod 9 can be inserted into and detached from the first hole 5, thereby achieving quick fixation and detachment between the filter plate 3 and the support plate 4.
[0031] The bottom surface of the furnace body 1 is fixedly connected to a support leg 25, and the bottom surface of the support leg 25 is fixedly connected to a rubber pad 26.
[0032] Specifically: the design of the support legs 25 and the rubber pads 26 makes the operation of the electrode hot water boiler more stable and enhances its insulation performance.
[0033] The outer surface of the furnace body 1 is fixedly connected with a lifting lug 29, and the outer surface of the lifting lug 29 is rounded.
[0034] Specifically, the design of the lifting lugs makes the electrode hot water boiler easier to install and reduces its sharp edges, thus lowering the probability of workers being bumped and injured.
[0035] A water outlet pipe 24 is fixedly connected to the bottom surface of the furnace body 1, and an air outlet 27 is fixedly connected to the upper surface of the top cover 11.
[0036] Specifically: The design of the water outlet pipe 24 and the air outlet 27 makes it more convenient for the electrode hot water boiler to discharge wastewater and hot steam.
[0037] A support frame 22 is fixedly connected to the bottom end of the support shaft 12, and a heating electrode 23 is fixedly connected to the bottom surface of the support frame 22.
[0038] Specifically: Through the design of the support frame 22 and the heating electrode 23, the heating inside the furnace body 1 is more uniform, and the heating electrode 23 has stronger support and will not easily shake.
[0039] A first limiting plate 14 is fixedly connected to the top of the support shaft 12, and a second limiting plate 15 is fixedly connected to the outer surface of the support shaft 12.
[0040] Specifically, the design of the first limiting plate 14 at the top of the support shaft 12 and the second limiting plate 15 on the outer surface of the support shaft makes the support shaft 12 more stable during up and down movement, reducing the probability of it coming off.
[0041] Working principle: The operator holds the tops of the two sliding plates 8 with one hand, compressing the spring 7. This causes the two sliding plates 8 to slide the locking rod 9 inside the limiting box 6 until the locking rod 9 is completely disengaged from the first hole 5. Simultaneously, the other hand pulls the filter plate 3 outward from the first pipe 2. When a new filter plate needs to be inserted, the tops of the two sliding plates 8 are first held, compressing the spring 7. The filter plate 3 is then pushed into the first pipe 2. After the filter plate 3 is fully inside the first pipe 2, the two sliding plates 8 are released. The release of the spring 7 pushes the sliding plates 8, causing the locking rod 9 to slide outward simultaneously. The locking rod 9 enters the first hole 5, allowing the filter plate 3 and the support plate 4 to be quickly pulled out and locked. When the water level inside the furnace body 1 needs to be changed, the operator needs to pull the actuating plate 16 to make the sliding cylinder 28 rotate around the support shaft 12, thereby causing the sliding rod 17 and the limiting rod 18 to completely disengage from the support shaft 21. Then, the sliding rod 17 is slid to the required position. At this time, the actuating plate 16 is pulled again to make the sliding cylinder 28 rotate around the support shaft 12, thereby causing the limiting rod 18 on the outer surface of the sliding rod 17 to completely enter the interior of the support shaft 21, achieving the purpose of moving the heating electrode 23 inside the furnace body 1.
[0042] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
