Description

Technical Field

[0001] This utility model relates to the field of evaporator technology, and in particular to an automatic cleaning evaporator. Background Technology

[0002] Evaporation is a physical process in which a liquid transforms 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, among which the evaporator used in refrigeration systems is one type. The evaporator is a very important component of the four major components of refrigeration. Low-temperature condensed liquid passes through the evaporator and exchanges heat with the outside air, vaporizing and absorbing heat to achieve the cooling effect. The evaporator mainly consists of two parts: a heating chamber and an evaporation chamber. The heating chamber provides the heat required for evaporation to the liquid, causing the liquid to boil and vaporize; the evaporation chamber completely separates the gas and liquid phases.

[0003] In practical applications, wastewater contains complex components, including impurities such as salt deposits, colloids, and oil stains. These substances easily form an adhesion layer on the inner wall of the heat exchange tubes, significantly reducing heat exchange efficiency. Traditional cleaning methods mainly rely on manual cleaning or chemical solvent rinsing to remove dirt from the inside of the tubes.

[0004] However, while existing automated solvent flushing methods can effectively remove dirt from inside the tubes, their long cleaning cycle inevitably affects the normal operation of the equipment. In addition, the continuous deposition of dust carried by external airflow on the surface of the heat exchange tubes will further deteriorate the heat exchange performance. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the existing technology where the method of rinsing the inner cavity of the heat exchange tube with chemical solution is too time-consuming, and the adhesion of impurities when external dust-laden gas is blown onto the heat exchange tube will also reduce its heat exchange performance. Therefore, an automatic cleaning evaporator is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic cleaning evaporator includes an evaporator tank and heat exchange tubes fixedly installed inside the evaporator tank. It further includes: a support frame fixedly connected to the heat exchange tubes, wherein a first threaded sleeve is fixedly installed on the support frame, a first lead screw is threadedly connected to the first threaded sleeve, and a cleaning brush head is fixedly connected to one end of the first lead screw, the cleaning brush head being located above the water inlet of the heat exchange tubes; a pushing member disposed on the evaporator tank, wherein when the pushing member moves, the cleaning brush head tends to penetrate deeper into the inner cavity of the heat exchange tubes; and a scraper sleeved on the heat exchange tubes, wherein the scraper is provided with a driving member, and when the driving member operates, the scraper moves vertically along the heat exchange tubes.

[0008] In order to drive the cleaning brush head to move into the inner cavity of the heat exchange tube, preferably, the pushing component includes an electric telescopic rod fixedly installed on the evaporator, the telescopic end of the electric telescopic rod passing through the evaporator and fixedly connected to a fixing plate, and the side of the fixing plate away from the electric telescopic rod being rotatably connected to a first lead screw.

[0009] To further guide and limit the fixed plate, a limiting sleeve is fixedly connected to the fixed plate, and a limiting rod is slidably connected inside the limiting sleeve. The two ends of the limiting rod are fixedly connected to the evaporator and the heat exchange tube, respectively.

[0010] To drive the scraper to move along the outer wall of the heat exchange tube and clean the adhering impurities, preferably, the driving component includes: a second threaded sleeve fixedly connected to the scraper, wherein the inner cavity of the second threaded sleeve is threadedly connected to a second lead screw, and the two ends of the second lead screw are rotatably connected to the evaporator and the heat exchange tube respectively; a positioning frame fixedly connected to the evaporator, wherein a motor is fixedly installed on the positioning frame, the output end of the motor passes through the evaporator and is fixedly connected to a first bevel gear, and a second bevel gear fixedly connected to the second lead screw is meshed on the first bevel gear.

[0011] To guide and limit the movement of the scraper, preferably, a sliding sleeve is fixedly connected to the scraper, and a sliding rod is slidably connected inside the sliding sleeve. The two ends of the sliding rod are fixedly connected to the evaporator and the heat exchange tube, respectively.

[0012] To achieve cleaning of the outer wall of the heat exchange tube, preferably, the scraper consists of a circular plate and a sleeve, with the sleeve fitted over the outside of the heat exchange tube.

[0013] To further improve the cleaning quality of the heat exchange tube outer wall, both ends of the sleeve are tapered.

[0014] To improve the cleaning quality of the inner wall of the heat exchange tube, the cleaning brush head is preferably conical in shape.

[0015] Compared with the prior art, this utility model provides an automatic cleaning evaporator, which has the following beneficial effects:

[0016] 1. This automatic cleaning evaporator, through the setting of the pushing component, when the electric telescopic rod drives the fixed plate to move downward, the first lead screw and the first threaded sleeve form a helical pair transmission, causing the cleaning brush head to rotate and sweep in the inner cavity of the heat exchange tube, effectively removing the dirt attached to the inner wall of the heat exchange tube, thereby ensuring its high-efficiency heat transfer performance.

[0017] 2. This automatic cleaning evaporator, through the setting of the driving component, when the output end of the motor drives the first bevel gear to rotate, the second threaded sleeve drives the scraper to move along the surface of the heat exchange tube, thereby removing the impurities adhering to the surface and effectively improving the heat exchange efficiency of the heat exchange tube.

[0018] 3. This automatic cleaning evaporator features a tapered cleaning brush head with a smaller diameter at the front and a larger diameter at the rear, creating a mechanical structure that guides the flow of dirt from the front and presses it back. The front end contacts the dirt layer first and begins to peel it off, while the rear end increases the contact area to achieve secondary cleaning, effectively preventing dirt residue.

[0019] The parts not mentioned in this device are the same as or can be implemented using existing technology. This utility model drives the first lead screw to feed axially through the pusher, so that the cleaning brush head can move axially along the inner cavity of the heat exchange tube while rotating, realizing a dynamic cleaning process and significantly improving the removal effect of dirt on the inner wall of the heat exchange tube. At the same time, the drive unit controls the scraper to scrape along the outer wall of the heat exchange tube, which can efficiently remove impurities attached to the outer wall, realizing an integrated operation of simultaneous cleaning of the inner and outer walls of the heat exchange tube.

[0028] Example:

[0029] Reference Figures 1-5 An automatic cleaning evaporator includes an evaporator tank 1 and heat exchange tubes 2 fixedly installed inside the evaporator tank 1. It also includes a support frame 3 fixedly connected to the heat exchange tubes 2. A first threaded sleeve 4 is fixedly installed on the support frame 3. A first lead screw 5 is threadedly connected to the inner cavity of the first threaded sleeve 4. A cleaning brush head 6 is fixedly connected to one end of the first lead screw 5. The cleaning brush head 6 is located above the water inlet of the heat exchange tubes 2. The cleaning brush head 6 is conical in shape. The conical design results in a smaller diameter at the front end and a larger diameter at the rear end, forming a mechanical structure of front-leading and rear-pressure. The front end first contacts the dirt layer and initially peels it off. The rear end achieves secondary cleaning by increasing the contact area, effectively avoiding dirt residue; the pusher set on the evaporator 1, when the pusher moves, the cleaning brush head 6 tends to penetrate deeper into the inner cavity of the heat exchange tube 2; the scraper 8, sleeved on the heat exchange tube 2, is composed of a circular plate 81 and a sleeve 82. The sleeve 82 is sleeved on the outside of the heat exchange tube 2, and both ends of the sleeve are conical. When the scraper 8 moves on the heat exchange tube 2, the conical sleeve can effectively remove impurities adhering to the surface of the heat exchange tube 2. The scraper 8 is equipped with a drive component. When the drive component works, the scraper 8 moves vertically along the heat exchange tube 2.

[0030] Specifically, the first lead screw 5 is driven to feed axially by the pusher, so that the cleaning brush head 6 can move axially along the inner cavity of the heat exchange tube 2 while rotating, thus realizing a dynamic cleaning process and significantly improving the removal effect of dirt on the inner wall of the heat exchange tube 2. At the same time, the scraper 8 is controlled by the drive to scrape along the outer wall of the heat exchange tube 2, which can efficiently remove impurities attached to the outer wall, realizing an integrated operation of simultaneous cleaning of the inner and outer walls of the heat exchange tube 2.

[0031] The pushing component includes an electric telescopic rod 7 fixedly installed on the evaporator 1. The telescopic end of the electric telescopic rod 7 passes through the evaporator 1 and is fixedly connected to a fixing plate 71. The side of the fixing plate 71 away from the electric telescopic rod 7 is rotatably connected to the first lead screw 5. A limiting sleeve is fixedly connected to the fixing plate 71. A limiting rod is slidably connected inside the limiting sleeve. The two ends of the limiting rod are fixedly connected to the evaporator 1 and the heat exchange tube 2, respectively. Through the cooperation of the limiting sleeve and the limiting rod, the fixing plate 71 can be vertically limited.

[0032] Specifically, by setting up the pusher, when the electric telescopic rod 7 drives the fixed plate 71 to move downward, the first lead screw 5 and the first threaded sleeve 4 form a helical pair transmission, causing the cleaning brush head 6 to rotate and clean the inner cavity of the heat exchange tube 2, effectively removing the dirt attached to the inner wall of the heat exchange tube 2, thereby ensuring its efficient heat transfer performance.

[0033] The driving component includes: a second threaded sleeve 9, which is fixedly connected to the scraper 8. The inner cavity of the second threaded sleeve 9 is threadedly connected to a second lead screw 91, and the two ends of the second lead screw 91 are rotatably connected to the evaporator 1 and the heat exchange tube 2, respectively; a positioning frame 92 fixedly connected to the evaporator 1, and a motor 93 fixedly installed on the positioning frame 92. The output end of the motor 93 passes through the evaporator 1 and is fixedly connected to a first bevel gear 94. A second bevel gear 95, which is fixedly connected to the second lead screw 91, is meshed on the first bevel gear 94.

[0034] Specifically, by setting the driving component, when the output end of the motor 93 drives the first bevel gear 94 to rotate, the second threaded sleeve 9 drives the scraper 8 to move along the surface of the heat exchange tube 2, thereby removing the impurities adhering to its surface and effectively improving the heat exchange efficiency of the heat exchange tube 2.

[0035] A sliding sleeve is fixedly connected to the scraper 8, and a sliding rod is slidably connected inside the sliding sleeve. The two ends of the sliding rod are fixedly connected to the evaporator 1 and the heat exchange tube 2, respectively.

[0036] Specifically, the vertical movement of the scraper 8 can be limited by the cooperation of the sliding sleeve and the sliding rod, thereby improving its movement stability.

[0037] Working principle: When cleaning the inner wall of the heat exchange tube 2, the staff uses an external control switch to start the electric telescopic rod 7. When the telescopic end of the electric telescopic rod 7 moves, it drives the fixed plate 71 to move. When the fixed plate 71 moves, it drives the first lead screw 5 to move. When the first lead screw 5 moves in the inner cavity of the first threaded sleeve 4, it drives the cleaning brush head 6 to rotate. Because the front end of the cleaning brush head 6 is small and the rear end is large, the front end contacts the dirt layer first and initially peels it off. The rear end achieves secondary cleaning by increasing the contact area, effectively avoiding dirt residue.

[0038] When cleaning impurities on the outer wall of heat exchange tube 2, the staff starts motor 93 using an external control switch. When the output end of motor 93 rotates, it drives the first bevel gear 94 to rotate. When the first bevel gear 94 rotates, it drives the second bevel gear 95 to rotate. When the second bevel gear 95 rotates, it drives the second lead screw 91 to rotate. When the second lead screw 91 rotates, it drives the second threaded sleeve 9 to move. When the second threaded sleeve 9 moves, it drives the scraper 8 to move. The sleeve on the scraper 8 can effectively remove the impurities adhering to the outer wall of heat exchange tube 2.

[0039] Using scraper 8 and cleaning brush head 6 to clean the inner and outer walls of heat exchange tube 2 simultaneously not only significantly improves the heat transfer efficiency of heat exchange tube 2, but also extends the service life of heat exchange tube 2.

[0040] 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.
