Description

Technical Field

[0001] This utility model belongs to the field of heat exchanger technology, specifically relating to a high-efficiency U-tube volumetric heat exchanger. Background Technology

[0002] A volumetric heat exchanger is a heat exchanger that uses the alternating flow of cold and hot fluids across the surface of a heat storage medium in a heat storage chamber to exchange heat. In a volumetric heat exchanger with a partition wall, the cold and hot fluids are separated by a solid partition wall, and heat exchange occurs through this partition wall; therefore, it is also called a surface heat exchanger. The interior of a volumetric heat exchanger typically contains U-shaped tubes. In actual use, operators insert the U-shaped tube bundle into the cylinder through an opening on one side, connect it with a flange, and then reinforce the tank to ensure its airtightness. During heat exchange, the heat medium flows in from one inlet and out from one outlet. Inside the cylinder, the internal heat of the U-shaped tube bundle is transferred to the cold water outside the cylinder, and the resulting hot water flows out from the top of the cylinder.

[0003] Chinese patent publication number CN 219103818 U discloses a high-efficiency U-tube volumetric heat exchanger, including a volumetric heat exchanger body. A connecting pipe is fixedly connected to the outside of the volumetric heat exchanger body, and a cap is provided at the end of the connecting pipe. A mating ring is sleeved on the outside of the cap, and connecting blocks are symmetrically connected on the side of the mating ring away from the volumetric heat exchanger body. Each connecting block has a threaded groove inside, and a threaded rod is inserted into the threaded groove.

[0004] However, the current high-efficiency U-tube volumetric heat exchanger has the following problems: it cannot prevent fluid from entering the U-tube without clogging, and it cannot achieve the anti-clogging effect, which prevents fluid from entering the U-tube. Therefore, we propose a high-efficiency U-tube volumetric heat exchanger. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency U-tube volumetric heat exchanger that can solve the problem in related technologies where fluid cannot enter the U-tube without clogging and cannot achieve an anti-clogging effect, thus preventing fluid from entering the U-tube.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A high-efficiency U-tube volumetric heat exchanger includes a body and a feed pipe. The feed pipe is disposed on the outer surface of the body, and a fixing assembly is disposed on the outer surface of the body. An anti-clogging device is disposed inside the feed pipe. The anti-clogging device includes a fixing plate, a waterproof motor is fixedly inserted through the bottom of the fixing plate, a rotating shaft is fixedly connected to the end of the output shaft of the waterproof motor, a rotating plate is fixedly connected to the circumferential surface of the rotating shaft, a stop block is fixedly connected to the circumferential surface of the rotating plate, a filter plate is slidably connected to the inner wall of the feed pipe, and a force-bearing rod is fixedly connected to the bottom of the filter plate. This design facilitates the rotation of the rotating plate by the rotating shaft.

[0008] Preferably, the inner wall of the feed tube is provided with a groove, and one end of a spring is fixedly connected to the inner wall of the groove. The end of the spring away from the groove is fixedly connected to a slider. This design allows the slider to slide on the inner wall of the groove.

[0009] Preferably, the slider is slidably connected to the inner wall of the groove, the slider is engaged with the circumferential surface of the filter plate, and there are two sliders, which are symmetrical about each other along the vertical central axis of the filter plate. This design is beneficial for the filter plate to filter the fluid entering the feed pipe first.

[0010] Preferably, the feed pipe is provided with an auxiliary device, which includes a baffle that is snapped onto the inner wall of the feed pipe. The top of the baffle has a circular groove and a rectangular groove. One end of a force spring is fixedly connected to the inner wall of the rectangular groove, and an actuating block is fixedly connected to the end of the force spring away from the inner wall of the rectangular groove. This design allows the actuating block to be designed with an arc surface, which enables the actuating block to be pushed.

[0011] Preferably, a cover plate is fixedly connected to the side of the action block, and a rotating rod is snapped onto the circumferential surface of the rotating shaft. This design allows the cover plate to be circular in shape, which can match the circular groove.

[0012] Preferably, one end of the action block is set as an arc surface, the action block is slidably connected to the inner wall of the rectangular groove, and the diameter of the cover plate is larger than the diameter of the circular groove. This design is conducive to the fluid entering the circular groove and falling to the top of the filter plate, so that the filter plate performs filtration first.

[0013] Preferably, the number of the blocking blocks is set to four, in pairs, and symmetrical to each other along the vertical central axis of the rotating plate. One end of the blocking block is set as an arc surface, and one end of the force-bearing rod is set as an arc surface. This design is beneficial to the blocking blocks so that the force-bearing rod can be lifted upward by the force.

[0014] The technical effects achieved by this utility model are as follows:

[0015] This invention, through the setting of an anti-clogging device, enables the spring to use its own elastic force to drive the filter plate and the force rod to reset via the slider, repeating the cycle. This achieves an anti-clogging effect when the filter plate filters and isolates impurities in the fluid, effectively preventing the fluid from getting clogged after entering the U-shaped tube bend and ensuring that the fluid enters the U-shaped tube smoothly.

[0016] This invention, through the setting of an auxiliary device, enables the actuating block to be reset by the elastic force of the force spring, closing the circular groove, repeating the cycle, allowing the fluid to enter the feed pipe intermittently, and when the fluid is completely inside the body, the actuating block closes the circular groove, which can prevent external impurities from entering the interior of the body, enhance the sealing of the body, and allow the fluid to flow into the interior of the feed pipe in an orderly manner.

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figure 1-5As shown, a high-efficiency U-tube volumetric heat exchanger includes a body 1 and a feed pipe 2. The feed pipe 2 is disposed on the outer surface of the body 1, and a fixing assembly 3 is disposed on the outer surface of the body 1. An anti-clogging device 4 is disposed inside the feed pipe 2. The anti-clogging device 4 includes a fixing plate 41, a waterproof motor 42 is fixedly inserted through the bottom of the fixing plate 41, a rotating shaft 43 is fixedly connected to the end of the output shaft of the waterproof motor 42, a rotating plate 44 is fixedly connected to the circumferential surface of the rotating shaft 43, a blocking block 45 is fixedly connected to the circumferential surface of the rotating plate 44, a filter plate 46 is slidably connected to the inner wall of the feed pipe 2, and a force-bearing rod 47 is fixedly connected to the bottom of the filter plate 46. This design is beneficial to force the blocking block 45 to rotate when the rotating plate 44 rotates.

[0026] A cover plate 56 is fixedly connected to the side of the action block 55, and a rotating rod 57 is snapped onto the circumferential surface of the rotating shaft 43. This design makes it easier for the rotating rod 57 to be disassembled by the staff.

[0027] The slider 410 is slidably connected to the inner wall of the groove 48. The slider 410 is engaged with the circumferential surface of the filter plate 46. There are two sliders 410, which are symmetrical about each other along the vertical central axis of the filter plate 46. This design is beneficial to the filter plate 46 moving when the slider 410 slides on the inner wall of the groove 48 under force.

[0028] Based on the above structure, to prevent the fluid from clogging the U-shaped bend, an anti-clogging device 4 needs to be installed inside the feed pipe 2 to preferentially intercept impurities in the fluid. When the worker pours the fluid into the feed pipe 2, the filter plate 46 filters the fluid first. Then, the worker controls the waterproof motor 42 to start through the background control system, forcing the rotating shaft 43 to rotate counterclockwise. This causes the rotating plate 44 fixed on the circumference of the rotating shaft 43 to rotate counterclockwise, causing the stop block 45 to rotate along with the rotating plate 44. When the stop block 45 rotates counterclockwise... When in motion, the blocking block 45 and the force rod 47 come into contact with each other, forcing the force rod 47 to be forced to move the filter plate 46 upward. When the blocking block 45 continues to rotate until it no longer comes into contact with the force rod 47, the force rod 47 loses its thrust. The spring 49 can use its own elastic force to drive the filter plate 46 and the force rod 47 to reset through the slider 410. This cycle repeats, so that the filter plate 46 achieves the anti-clogging effect when filtering and isolating impurities in the fluid, effectively avoiding the situation of clogging after the fluid enters the U-shaped tube bend, and ensuring that the fluid enters the U-shaped tube smoothly.

[0029] like Figure 1-5 As shown, there are four blocking blocks 45, arranged in pairs and symmetrical to each other along the vertical central axis of the rotating plate 44. One end of the blocking block 45 is set as an arc surface, and one end of the force rod 47 is set as an arc surface. This design is beneficial to the force rod 47 being able to drive the filter plate 46 to move when it is under force.

[0030] The inner wall of the feed pipe 2 is provided with a groove 48. One end of a spring 49 is fixedly connected to the inner wall of the groove 48. The end of the spring 49 away from the groove 48 is fixedly connected to a slider 410. This design is beneficial for the spring 49 to use its own elastic force to drive the slider 410 to reset.

[0031] One end of the action block 55 is set as an arc surface. The action block 55 is slidably connected to the inner wall of the rectangular groove 53. The diameter of the cover plate 56 is larger than the diameter of the circular groove 52. This design is conducive to the cover plate 56 intermittently opening the circular groove 52, so that the circular groove 52 can intermittently discharge material.

[0032] An auxiliary device 5 is provided inside the feed pipe 2. The auxiliary device 5 includes a baffle 51, which is snapped onto the inner wall of the feed pipe 2. A circular groove 52 is provided on the top of the baffle 51, and a rectangular groove 53 is provided on the top of the baffle 51. One end of a force spring 54 is fixedly connected to the inner wall of the rectangular groove 53. An action block 55 is fixedly connected to the end of the force spring 54 away from the inner wall of the rectangular groove 53. This design is conducive to the force spring 54 driving the action block 55 to reset on the inner wall of the rectangular groove 53.

[0033] According to the above structure, in the anti-clogging device 4, in order to prevent the components in the anti-clogging device 4 from being damaged by impact or failing to block impurities when the fluid is poured into the feed pipe 2 too quickly, when the rotating shaft 43 rotates counterclockwise, it forces the rotating rod 57 to rotate counterclockwise. The rotating rod 57 and the arc surface of the action block 55 come into contact with each other, so that the action block 55 is forced to drive the cover plate 56 to slide on the inner wall of the rectangular groove 53, thereby opening the circular groove 52, allowing the fluid to enter the feed pipe 2 and flow into the interior of the body 1. When the rotating rod 57 continues to rotate counterclockwise, the rotating rod 57 no longer contacts the action block 55, and the action block 55 can be reset by the elastic force of the force spring 54, closing the circular groove 52. This cycle repeats, allowing the fluid to enter the feed pipe 2 intermittently. When the fluid is completely placed inside the body 1, the action block 55 closes the circular groove 52, which can prevent external impurities from entering the interior of the body 1, enhance the sealing of the body 1, and allow the fluid to flow into the interior of the feed pipe 2 in an orderly manner.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional methods in the field.
