Description

Technical Field

[0001] This utility model relates to the technical field of condensate collectors for wall-hung boilers, and more particularly to condensate collectors for wall-hung boilers. Background Technology

[0002] A condensate collector for a wall-hung boiler, also known as a condensate neutralizer or condensate treatment device, is a component of the flue system of a condensing wall-hung boiler. Its main function is to collect wastewater from the boiler, such as condensate from the condenser, condensate from the flue, and water generated by abnormal pressure relief from the pressure relief valve, in order to prevent water leakage from the boiler.

[0003] When existing condensate collectors are in use, wastewater often contains a lot of debris. During the process of wastewater being stored in the collector, the debris in the wastewater tends to adhere to the inner wall of the device. The long-term adhesion of numerous debris on the inner wall of the device may lead to corrosion and damage. Furthermore, as the amount of debris increases, it can accumulate into large clumps of debris and flow into subsequent pipelines, which may also cause blockages in the subsequent pipelines. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to provide a condensate collector for wall-hung boilers that can self-clean debris adhering to the inner wall of the water storage tank, so as to avoid corrosion and damage to the water storage tank or blockage of subsequent pipelines.

[0005] To solve the above problems, this utility model provides a wall-hung boiler condensate collector, including: a water storage shell, the top of which is fixedly and through-installed with a water inlet pipe one and a water inlet pipe two, and the bottom ends of the water inlet pipe one and the water inlet pipe two extend to the bottom of the water storage shell. A float plate is slidably installed inside a water storage shell, and both inlet pipe one and inlet pipe two slide through the float plate. Annular grooves are provided on the outer peripheral wall of the bottom of the float plate and at the positions corresponding to inlet pipe one and inlet pipe two. Annular pipes are provided in the annular grooves, and scraper rings are slidably provided in the openings of the annular grooves. The two annular walls of the annular pipes are fixedly connected to the inner annular wall of the corresponding annular groove and the corresponding scraper ring, respectively. The liquid injection mechanism, located at the top inside the float, is used for injecting liquid into the ring pipe.

[0006] Preferably, the water storage shell includes a top shell, a bottom shell, and a threaded cover. The top of the bottom shell is slidably inserted into the top shell, and the threaded cover is rotatably fitted onto the bottom of the bottom shell, and the threaded cover is threadedly connected to the bottom of the top shell.

[0007] Preferably, annular grooves are provided on the outer peripheral wall of the top of the water storage shell and at the positions of the corresponding water inlet pipe 1 and water inlet pipe 2. Sealing rings are slidably installed in the annular grooves, and several sealing rings are in contact with the inner wall of the bottom shell, the outer peripheral wall of water inlet pipe 1, and the outer peripheral wall of water inlet pipe 2, respectively.

[0008] Preferably, an electrically controlled pressure valve is fixedly installed inside the bottom opening of the bottom shell, and the top of the pressure sensor of the electrically controlled pressure valve is fixedly connected to the bottom side of the float plate by an elastic pull rope.

[0009] Preferably, the injection mechanism includes a water storage tank located at the top of the float plate. The water storage tank is arranged in a ring shape and positioned between several annular grooves. The interior of the water storage tank is connected to the interior of several annular pipes through a guide hole. A piston plate is slidably installed inside the water storage tank. Several circular holes are arranged in a circular array on the bottom side of the float plate corresponding to the position of the water storage tank. A circular rod is slidably installed inside the circular holes, and the top end of the circular rod is fixedly connected to the bottom side of the piston plate.

[0010] Preferably, a sealing ring is installed on the inner wall of the circular hole through an annular receiving groove, and the sealing ring is in contact with the outer peripheral wall of the corresponding circular rod. A connecting hole is opened on the top side of the float plate at the position corresponding to the circular hole, and the interior of the connecting hole is connected to the interior of the water storage tank.

[0011] This utility model has the following beneficial effects: This improved wall-hung boiler condensate collector can self-clean the inner wall of the water storage tank as wastewater is discharged, thus preventing the adhesion of a large amount of debris on the inner wall of the water storage tank. This avoids corrosion and damage to the water storage tank caused by the long-term adhesion of numerous debris on the inner wall of the water storage tank, and also prevents debris from accumulating on the inner wall of the water storage tank and flowing into subsequent pipelines, causing blockages in the subsequent pipelines.

[0015] To make the technical solution and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. Example

[0016] Reference Figure 1 , Figure 2 and Figure 3 The present invention discloses a wall-hung boiler condensate collector, comprising: a water storage shell 1, wherein a water inlet pipe 1 2 and a water inlet pipe 2 3 are fixedly installed through the top of the shell, and the bottom ends of the water inlet pipe 1 2 and the water inlet pipe 2 3 extend to the bottom of the water storage shell 1. A float plate 4 is slidably installed inside a water storage shell 1, and both water inlet pipe 1 2 and water inlet pipe 2 3 slide through the float plate 4. Annular grooves 5 are provided on the outer peripheral wall of the bottom of the float plate 4 and at the positions corresponding to water inlet pipe 1 2 and water inlet pipe 2 3. Annular pipes 6 are provided inside the annular grooves 5. Scraper rings 7 are slidably provided inside the opening of the annular grooves 5, and the two annular walls of the annular pipe 6 are fixedly connected to the inner annular wall of the corresponding annular groove 5 and the corresponding scraper ring 7, respectively. The liquid injection mechanism 8 is located at the top of the float plate 4 and is used for injecting liquid into the ring pipe 6.

[0017] In this embodiment, (please refer to...) Figure 1 and Figure 2 As shown, the top of inlet pipe 2 is the condensate inlet, and the top of inlet pipe 3 is Y-shaped, serving as the flue rainwater inlet and the pressure relief valve water inlet, respectively. These inlets are all connected to the corresponding drain outlets of the wall-hung boiler via inlet pipes (for guiding wastewater into the water storage tank 1). When using this improved wall-hung boiler condensate collector, please refer to... Figure 1 , Figure 2 and Figure 3As shown, wastewater flows into the water storage tank 1 through inlet pipe 2 and inlet pipe 3. The water pushes the float plate 4 upward by pushing it and the float plate 4 itself. Due to the water pushing the injection mechanism 8, the injection mechanism 8 draws out some water from the ring pipe 6. A pulling force towards the ring pipe 6 is applied to the scraper ring 7 by various positions of the inner ring wall of the scraper ring 7, so that the scraper ring 7 contracts and deforms and separates from the inner wall of the water storage tank 1 (the scraper ring 7 is a wear-resistant rubber ring). This reduces the friction between the float plate 4 and the inner wall of the water storage tank 1, making it easier for the float plate 4 to move upward. When the water in the water storage tank 1 is discharged, as the wastewater in the water storage tank 1 is lost, due to the friction between the float plate 4 and the inner wall of the water storage tank 1, the wastewater flowing out of the water storage tank 1 will first exert a downward pulling force on the injection mechanism 8, thereby injecting a corresponding amount of water into the ring pipe 6. Then, the scraper ring 7 will be pushed towards the inner wall of the water storage tank 1 by various positions of the inner ring wall of the scraper ring 7, causing the scraper ring 7 to expand and deform and stick tightly to the inner wall of the water storage tank 1. Then, the float plate 4 will be driven to move down, so that the scraper ring 7 and the moving float plate 4 will scrape off the attached substances on the inner wall of the water storage tank 1 and dissolve them in the wastewater and be discharged together. When in use, this improved wall-hung boiler condensate collector can self-clean the inner wall of the water storage tank 1 as wastewater is discharged, thereby preventing the adhesion of a large amount of debris on the inner wall of the water storage tank 1. This avoids corrosion and damage to the water storage tank 1 caused by the long-term adhesion of numerous debris on the inner wall of the water storage tank 1, and also prevents debris from accumulating on the inner wall of the water storage tank 1 and flowing into subsequent pipelines, causing blockages in the subsequent pipelines.

[0018] In a further preferred embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the water storage shell 1 includes a top shell 11, a bottom shell 12 and a threaded cover 13. The top of the bottom shell 12 is slidably inserted into the top shell 11, and the threaded cover 13 is rotatably sleeved on the bottom of the bottom shell 12, and the threaded cover 13 is threadedly connected to the bottom of the top shell 11. In this embodiment, (please refer to...) Figure 1 and Figure 2 As shown, the bottom opening of the bottom shell 12 is a combined condensate drain outlet, to which a pipe is connected to guide the water to the corresponding discharge location. Please refer to... Figure 1 and Figure 2 As shown, when the float plate 4 and scraper ring 7 are aged and damaged, the user unscrews the threaded rod from the top shell 11, then pulls the bottom shell 12 directly out of the top shell 11. After that, a new bottom shell 12, float plate 4 and scraper ring 7 are directly inserted into the top shell 11, and the threaded cover 13 is put back on the bottom shell 12 and screwed onto the bottom of the top shell 11. In this way, the top shell 11, bottom shell 12 and threaded cover 13 can be assembled into a complete water storage shell 1 for use, which facilitates the maintenance of the device.

[0019] In a further preferred embodiment of this utility model, such as Figure 2 , Figure 3 and Figure 4 As shown, annular grooves 9 are provided on the outer peripheral wall of the top of the water storage shell 1 and at the positions of the corresponding water inlet pipe 2 and water inlet pipe 3. Sealing rings 10 are slidably installed in the annular grooves 9, and several sealing rings 10 are in contact with the inner wall of the bottom shell 12, the outer peripheral wall of the water inlet pipe 2 and the outer peripheral wall of the water inlet pipe 3 respectively. In this embodiment, please refer to 2. Figure 3 and Figure 4 As shown, the sealing ring 10 can seal the gaps between the float plate 4 and the inner wall of the bottom shell 12, as well as between the float plate 4 and the water inlet pipe 1 and the water inlet pipe 2, facilitating the pushing and pulling of the float plate 4 by the wastewater in the water storage shell 1.

[0020] In a further preferred embodiment of this utility model, such as Figure 2 As shown, an electrically controlled pressure valve 20 is fixedly installed inside the bottom opening of the bottom shell 12, and the top of the pressure sensor of the electrically controlled pressure valve 20 is fixedly connected to the bottom side of the float plate 4 through an elastic pull rope 21. In this embodiment, please refer to Figure 2 As shown, when the float 4 moves to the corresponding height, a pulling force can be applied to the pressure sensor of the electrically controlled pressure valve 20 by pulling the rope (the electrically controlled pressure valve 20 is mainly composed of: waterproof shell, pressure sensor, electrically controlled valve and controller), so that the electrically controlled pressure valve 20 opens for a corresponding time, so that the wastewater in the water storage tank 1 is automatically discharged after reaching the corresponding amount.

[0021] In a further preferred embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the liquid injection mechanism 8 includes a water storage tank 81, which is opened at the top of the float plate 4. The water storage tank 81 is arranged in a ring and is located between several annular grooves 9. The interior of the water storage tank 81 is connected to the interior of several annular pipes 6 through a guide hole. A piston plate 82 is slidably installed in the water storage tank 81. Several circular holes 83 are opened in a circular array on the bottom side of the float plate 4 corresponding to the position of the water storage tank 81. A circular rod 84 is slidably installed in the circular holes 83, and the top end of the circular rod 84 is fixedly connected to the bottom side of the piston plate 82. In this embodiment, please refer to Figure 2 and Figure 3 As shown, when the wastewater pushes the float plate 4 upward, due to the friction between the float plate 4 and the inner wall of the water storage tank 1, some wastewater flows into the round hole 83, thereby pushing the piston plate 82 upward through the round rod 84 until the piston plate 82 and the inner wall of the water storage tank 81 come into contact with each other, so that some water in the ring pipe 6 is sucked into the water storage tank 81 through the water storage tank 81 and the guide hole, causing the ring pipe 6 to contract and deform. When the water in the water storage shell 1 is discharged, due to the friction between the float plate 4 and the inner wall of the water storage shell 1, the water in the round hole 83 flows out first, thereby pulling the piston plate 82 downward through the round rod 84, so that some water is forced into the ring pipe 6 through the water storage tank 81 and the guide hole, causing the ring pipe 6 to expand and deform.

[0022] In a further preferred embodiment of this utility model, such as Figure 3 and Figure 4 As shown, a sealing ring 85 is installed on the inner wall of the circular hole 83 through an annular receiving groove, and the sealing ring 85 is in contact with the outer peripheral wall of the corresponding circular rod 84. A connecting hole 86 is opened on the top side of the float plate 4 at the position corresponding to the circular hole 83, and the interior of the connecting hole 86 is connected to the interior of the water storage tank 81. In this embodiment, please refer to Figure 4 As shown, the sealing ring 85 can seal the gap between the round rod 84 and the inner wall of the round hole 83 to prevent water in the water storage tank 81 from flowing out through the round hole 83; The connection hole 86 allows the top of the water storage tank 81 to freely exchange gas with the top of the water storage shell 1, thereby preventing the formation of high and low pressure chambers in the top of the water storage tank 81 when the piston plate 82 moves within the water storage tank 81, which would affect the normal use of the device.

[0023] Working principle: When this improved wall-hung boiler condensate collector is in use, wastewater flows into the water storage tank 1 through inlet pipe 2 and inlet pipe 3, thereby pushing the float plate 4 upward. When the height of the float plate 4 reaches the threshold, the electrically controlled pressure valve 20 opens, allowing the wastewater in the water storage tank 1 to be discharged. As the wastewater in the water storage tank 1 is discharged, the float plate 4 moves downward and scrapes off the debris attached to the inner wall of the water storage tank 1 through the expanding scraper ring 7, which dissolves in the wastewater in the water storage tank 1 and is discharged from the water storage tank 1 along with the wastewater.

[0024] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
