Description
Technical Field
[0001] This utility model relates to the field of evaporator technology, specifically an evaporator with automatic descaling function. Background Technology
[0002] Evaporation is a physical process in which a liquid is transformed into a gas. Generally speaking, an evaporator is an object that transforms a liquid substance into a gas. There are a large number of evaporators in industry. They pass low-temperature condensed liquid through the evaporator to exchange heat with the outside air, and the liquid vaporizes and absorbs heat to achieve evaporation.
[0003] During the use of an evaporator, scale or residue will be left inside the heat exchange tubes of the evaporator as the liquid to be evaporated. The existing descaling method is to stop the evaporator from working, then disassemble the evaporator, and then use special tools to descale the inner cavity of the heat exchange tubes. This descaling method is not only cumbersome to operate, but also requires stopping the operation of the evaporator during descaling, which affects the orderly use of the evaporator.
[0004] Therefore, this utility model provides an evaporator with automatic descaling function to solve the above problems. Utility Model Content
[0005] This utility model provides an evaporator with automatic descaling function. The baffle allows water entering the main shell to flow evenly into the liquid guide tube. The liquid guide tube is wider at the left and right and narrower in the middle, which increases the flow rate of the water entering the liquid guide tube. The increased flow rate drives the fan blades inside the liquid guide tube to rotate. The rotation of the fan blades causes the rotating rod to rotate, thereby allowing the bristles to descale the inner wall of the heat exchange tube.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] An evaporator with automatic descaling function includes a main shell. A first sub-shell is fixedly installed on the left side of the main shell, and a drain pipe is fixedly inserted into the side of the first sub-shell. A second sub-shell is fixedly installed on the right side of the main shell, and an inlet pipe is fixedly inserted into the side of the second sub-shell. An exhaust pipe is fixedly inserted into the top of the main shell, and a throttling valve is fixedly inserted into the bottom of the main shell. Sealing plates are fixedly installed on both sides of the inner cavity of the main shell, and multiple evenly distributed heat exchange tubes are fixedly installed between the two sealing plates. A partition is fixedly installed inside the second sub-shell, and multiple liquid guide pipes connected to the heat exchange tubes are fixedly inserted into the side of the partition. A descaling component is installed inside the liquid guide pipes to descal the inner cavity of the heat exchange tubes.
[0008] As a further optimization, the descaling assembly includes two crossbars fixedly installed on both sides of the inner wall of the liquid guide tube, a ring fixedly installed between the two crossbars, a rotating rod rotatably installed inside the ring via a waterproof bearing, the rotating rod extending into the corresponding heat exchange tube, and brush bristles tightly attached to the inner wall of the heat exchange tube fixedly installed on the side of the rotating rod, and a fan blade fixedly installed at the end of the rotating rod located inside the liquid guide tube.
[0009] As a further optimization, both the crossbar and the ring are tapered on the side closest to the fan blade.
[0010] As a further optimization, the side of the liquid guide tube is flush with the side of the partition.
[0011] As a further optimization, the inner cavity of the liquid guide tube has a structure that is thicker at both ends and thinner in the middle.
[0012] As a further optimization, a flange ring is provided at one end of the drain pipe, inlet pipe, vent pipe, and throttle valve.
[0013] As a further optimization, the surfaces of the fan blades and the rotating rod are coated with an anti-rust layer.
[0014] Compared with the prior art, the beneficial effects of this application are as follows:
[0015] A baffle and a liquid guide pipe are installed at one end of the heat exchange tube. The baffle allows water entering the main shell to flow evenly into the liquid guide pipe. The liquid guide pipe is wider at the left and right and narrower in the middle, which increases the flow rate of the water entering the liquid guide pipe. The increased flow rate drives the fan blades inside the liquid guide pipe to rotate. The rotation of the fan blades causes the rotating rod to rotate, thereby allowing the bristles to descale the inner wall of the heat exchange tube, improving the efficiency of the device. Moreover, the descaling of the device is carried out during the use of the device and does not require external machine power, saving the operating cost of the device. Attached Figure Description

[0021] 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.
[0022] This utility model provides an evaporator with automatic descaling function, such as... Figures 1 to 4 As shown, in one embodiment, the evaporator includes a main shell 1, a first auxiliary shell 2 fixedly installed on the left side of the main shell 1, a drain pipe 4 fixedly inserted into the side of the first auxiliary shell 2, a second auxiliary shell 3 fixedly installed on the right side of the main shell 1, an inlet pipe 5 fixedly inserted into the side of the second auxiliary shell 3, an exhaust pipe 6 fixedly inserted into the top of the main shell 1, a throttling valve 7 fixedly inserted into the bottom of the main shell 1, sealing plates 9 fixedly installed on both sides of the inner cavity of the main shell 1, a plurality of evenly distributed heat exchange tubes 8 fixedly installed between the two sealing plates 9, a partition plate 10 fixedly installed inside the second auxiliary shell 3, a plurality of liquid guiding pipes 11 fixedly inserted into the side of the partition plate 10 and respectively connected to the heat exchange tubes 8, and a descaling component is provided in the liquid guiding pipe 11 for descaling the inner cavity of the heat exchange tubes 8.
[0023] Based on the above embodiments, the descaling assembly includes two crossbars 14 fixedly installed on both sides of the inner wall of the liquid guide tube 11, a ring 15 fixedly installed between the two crossbars 14, a rotating rod 12 rotatably installed inside the ring 15 via a waterproof bearing, the rotating rod 12 extends into the corresponding heat exchange tube 8, and bristles 13 tightly attached to the inner wall of the heat exchange tube 8 are fixedly installed on the side of the rotating rod 12, and a fan blade 16 is fixedly installed at one end of the rotating rod 12 located inside the liquid guide tube 11.
[0024] Furthermore, the crossbar 14 and the ring 15 in the descaling assembly are both tapered on the side near the fan blade 16. The tapered design can prevent the crossbar 14 and the ring 15 from blocking the water flow.
[0025] Preferably, the side of the liquid guide tube 11 is flush with the side of the partition 10.
[0026] The inner cavity of the liquid guide tube 11 is thicker at both ends and thinner in the middle, which allows the water flow to increase its velocity inside the liquid guide tube 11 after entering from the right side.
[0027] To facilitate the connection of the various components, a flange ring is provided at one end of the drain pipe 4, the inlet pipe 5, the vent pipe 6, and the throttle valve 7.
[0028] Preferably, the surfaces of the fan blade 16 and the rotating rod 12 are coated with an anti-rust layer to prevent the fan blade 16 and the rotating rod 12 from rusting and affecting the normal use of the device.
[0029] Working principle:
[0030] First, the main housing 1 is installed in the designated position. Then, water flows into the main housing 1 through the inlet pipe 5. After that, coolant is introduced into the main housing 1 through the throttle valve 7. During this process, as the water flows through the heat exchange tube 8, the coolant absorbs the heat from the heat exchange tube 8 and forms steam. The steam is discharged from the exhaust pipe 6. In this process, after the water flows into the second sub-housing 3, the water flow is first intercepted by the baffle 10. Then, the water flows into the guide pipe 11 one by one. The water entering the guide pipe 11 will have its flow rate increased due to the size of the guide pipe 11, thereby driving the fan blade 16 to rotate. The rotation of the fan blade 16 can drive the rotating rod 12 to rotate. The rotation of the rotating rod 12 can allow the bristles 13 to scrub the inner wall of the heat exchange tube 8, so that scale will not accumulate in the heat exchange tube 8 and thus no blockage will occur.
[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
