Description

Technical Field

[0001] The utility model relates to the technical field of evaporator descaling, in particular to an evaporator descaling component. Background Art

[0002] Evaporator descaling components usually refer to components used to remove accumulated dirt and scale inside the evaporator. The design of these components aims to ensure the long-term operation of the evaporator and maintain high efficiency.

[0003] In the prior art, a flexible hose is inserted into the evaporator pipe, and the dirt is removed by continuously flushing with an acidic cleaning solution.

[0004] The inventor of the present utility model has found that although the above-mentioned descaling method in the prior art can achieve rapid descaling, the entire process requires flushing with an acidic cleaning solution. This method not only consumes a large amount of acidic cleaning solution, but also the acidic cleaning solution is prone to overflow or splash during the flushing process, which easily causes corrosion of other components of the equipment and affects the operation of the equipment.

[0005] Therefore, we propose an evaporator descaling component. Content of the Utility Model

[0006] The present utility model mainly solves the technical problems existing in the above-mentioned prior art, and provides an evaporator descaling component.

[0007] To achieve the above object, the present utility model adopts the following technical solution. An evaporator descaling component includes a main pipe made of a hard material. The lower end of the main pipe is connected with a cleaning head for extending into the evaporator pipe. The lower end of the cleaning head is connected with an isolation sponge. The isolation sponge is a disc-shaped structure made of sponge material with the edge bent upward. An adapter pipe is fixedly connected inside the cleaning head. The main pipe is connected to the inside of the cleaning head and connected to the adapter pipe and communicated to the lower end of the cleaning head through the adapter pipe.

[0008] Preferably, six springs are installed on the outer wall surface of the adapter pipe. Every two corresponding to the same vertical position form a pair. All the springs are directed towards the central position of the adapter pipe column. The ends of the two groups of springs at the same vertical position away from the adapter pipe are connected with a support scraper. The support scraper extends to the outside of the cleaning head through a groove opened on the surface of the cleaning head.

[0009] Preferably, the position where the support scraper contacts the evaporator pipe is pointed.

[0010] Preferably, three groups of scraper groups are fixedly connected to the outer wall surface of the top of the cleaning head at an angle of 120 degrees. Each scraper group consists of a connecting rod and an arc-shaped scraper. The scraper is in close contact with the inner wall of the evaporator pipe.

[0011] Preferably, edges are connected to the upper and lower edges of the scraping blades of the scraping blade group.

[0012] Preferably, a water storage box with a hollow interior is fixedly connected to the top position of the cleaning head. The water storage box is connected to an external water pump through a water inlet pipe, and multiple groups of nozzles are fixed at the edge of the water storage box. The water outlet positions of a part of the nozzles correspond to the positions of the scraping blades of the scraping blade group.

[0013] Beneficial effects

[0014] The present utility model provides a scale removal component for an evaporator, having the following beneficial effects:

[0015] This scale removal component for an evaporator can ensure that the acidic cleaning liquid only contacts the interior of the evaporator pipes, and neither contacts other parts of the evaporator during injection nor during discharge.

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Embodiment 1: A scale removal assembly for an evaporator, as Figures 1 to 4 shown, includes a main pipeline 1 made of hard material. The lower end of the main pipeline 1 is connected with a cleaning head 2 for extending into the inner part of the evaporator pipeline. The lower end of the cleaning head 2 is connected with an isolation sponge 3. As Figure 2 shown, the isolation sponge 3 is a disc-shaped structure made of sponge material with the edge bent upward. An connecting pipe 4 is fixedly connected inside the cleaning head 2. The main pipeline 1 is connected to the inside of the cleaning head 2 and connected with the connecting pipe 4 and communicated to the lower end of the cleaning head 2 through the connecting pipe 4.

[0027] During cleaning, the lower end of the evaporator pipeline to be cleaned is blocked. The scale removal assembly is inserted from the upper end of the evaporator pipeline to be cleaned. The isolation sponge 3 blocks the upper end of the evaporator pipeline to be cleaned. By setting the isolation sponge 3 to have a shape with the edge bent upward, it is convenient for the installation of the entire scale removal assembly and makes it easier to enter the evaporator pipeline. After the scale removal assembly is installed, an acidic cleaning solution is injected into the evaporator pipeline through the main pipeline 1 and left standing for a period of time. The acidic cleaning solution reacts chemically with the dirt to dissolve the dirt. At this time, the upper end of the main pipeline 1 is connected to a sewage collection box through a hose and the main pipeline 1 is repeatedly pushed downward. The main pipeline 1 drives the isolation sponge 3 to move downward to increase the pressure inside the evaporator pipeline, so that the solution after reacting with the dirt can be discharged out along the main pipeline 1 under the action of pressure and accurately collected. This device can ensure that the acidic cleaning solution only contacts the inside of the evaporator pipeline and will not contact other parts of the evaporator during its injection and discharge processes, which not only reduces the consumption of the cleaning agent but also protects other parts from corrosion.

[0028] Embodiment 2:

[0029] On the basis of the above embodiment, as Figures 3 to 4As shown in the figure, six springs 6 are installed on the outer wall surface of the connecting pipe 4. Every two springs corresponding to the same vertical position form a pair. All the springs 6 are oriented towards the center position of the cylinder of the connecting pipe 4. At the ends of the two groups of springs 6 at the same vertical position that are far away from the connecting pipe 4, a supporting scraping plate 5 is connected. The supporting scraping plate 5 passes through the groove formed on the surface of the cleaning head 2 and extends to the outside of the cleaning head 2.

[0030] By setting the supporting scraping plate 5 and the springs 6, it can ensure that the entire descaling component remains in a stable state when entering the inner part of the evaporator pipeline. The three groups of supporting scraping plates 5 expand outwards under the elastic force of the springs 6 and form a supporting state with the inner wall of the evaporator pipeline, ensuring the sealing performance at the contact position between the isolation sponge 3 and the evaporator pipeline, and preventing the descaling component from tilting after entering the inner part of the evaporator pipeline, thus avoiding the leakage of the acidic cleaning liquid.

[0031] The position where the supporting scraping plate 5 contacts the evaporator pipeline is pointed. The pointed supporting scraping plate 5 can reduce the contact area with the inner wall of the evaporator pipeline. When pulling the main pipeline 1 to move the cleaning head 2 up and down inside the evaporator pipeline, slightly rotating the main pipeline 1 will drive the supporting scraping plate 5 to move and rotate inside the evaporator pipeline to scrape off stubborn dirt.

[0032] Embodiment 3:

[0033] Based on the above embodiment, as Figures 3 to 5 shown in the figure, three groups of scraper groups 7 are fixedly connected to the outer wall surface of the top of the cleaning head 2 at an angle of 120 degrees. The scraper group 7 is composed of a connecting rod and an arc-shaped scraper. The scraper is in close contact with the inner wall of the evaporator pipeline. When pulling the main pipeline 1 to move the cleaning head 2 up and down inside the evaporator pipeline, the scraper group 7 can scrape the inner wall of the evaporator pipeline to remove stubborn dirt. At the upper and lower edges of the scraper of the scraper group 7, a cutting edge 8 is connected. Adding the cutting edge 8 can more efficiently remove the attached dirt that has not been dissolved on the evaporator pipeline.

[0034] A water storage box 9 with a hollow interior is fixedly connected to the top position of the cleaning head 2. The water storage box 9 is connected to an external water pump through a water inlet pipe 11. Multiple groups of nozzles 10 are fixedly connected to the edge of the water storage box 9. The water outlet positions of a part of the nozzles 10 correspond to the positions of the scrapers of the scraper group 7.

[0035] High-pressure clean water is injected into the interior of the water storage box 9 through the water inlet pipe 11. The clean water is sprayed out through the nozzles 10 to wash the positions of the scrapers of the scraper group 7 to make the dirt fall off. Finally, the entire main pipeline 1 is pulled upwards to move the isolation sponge 3 upwards to take out all the fallen dirt and the washed clean water, realizing the final cleaning. After the clean water and dirt are discharged, they are collected separately, and the clean water will not corrode other components of the equipment.

[0036] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above-mentioned embodiments. What is described in the above-mentioned embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements fall within the scope of the present utility model claimed.
