Description

Technical Field

[0001] This utility model relates to the field of heat exchanger cleaning, and in particular to a shell-and-tube heat exchanger cleaning device. Background Technology

[0002] Shell-and-tube heat exchangers are the most widely used, oldest, and most technologically mature type of heat exchanger. Their core design concept is to use tube bundles as heat transfer surfaces, allowing two fluids at different temperatures to flow and exchange heat through the tube walls.

[0003] During long-term operation, scale, oil, and other impurities easily accumulate on the inner wall of shell-and-tube heat exchangers, leading to a significant decrease in heat exchange efficiency and affecting production safety. Therefore, it is necessary to clean the impurities inside the tube wall regularly to avoid affecting production. Currently, most traditional methods for cleaning shell-and-tube heat exchangers involve manual rotation using tools to clean the inner wall, which is not only inefficient but also labor-intensive. To address this issue, a shell-and-tube heat exchanger cleaning device is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a shell-and-tube heat exchanger cleaning device, which aims to improve the current traditional shell-and-tube heat exchanger cleaning method, which is mostly manual cleaning of the inner wall by manually rotating the tube with tools, which is not only inefficient but also labor-intensive.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a shell-and-tube heat exchanger cleaning device, comprising a first mounting plate, a groove formed on the outer wall of the first mounting plate, a sliding rod slidably connected in the groove, a rack fixedly connected to the front side of the sliding rod, and multiple gears meshing on the lower side of the rack, and multiple cleaning pipes rotatably connected through and piercing the middle of the first mounting plate, the cleaning pipes being fixedly connected through and piercing the gears, and a rotating joint rotatably connected to the front end of the multiple cleaning pipes.

[0006] As a further description of the above technical solution: a second mounting plate is fixedly connected to the upper part of the first mounting plate, and a cylinder is installed on the front side of the second mounting plate.

[0007] As a further description of the above technical solution:

[0008] A sliding rod is fixedly connected to the left side of the cylinder via an output rod, and the lower end of the sliding rod is fixedly connected to a rack.

[0009] As a further description of the above technical solution:

[0010] A handle is fixedly connected to the front side of the No. 1 mounting plate.

[0011] As a further description of the above technical solution:

[0012] The cleaning tube has multiple holes arranged in a regular pattern.

[0013] As a further description of the above technical solution:

[0014] The cleaning tube is fitted with a brush strip, which is spiral in shape.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, by installing a gear at the front end of the cleaning tube and setting a cylinder on the upper part of the mounting plate, the cylinder drives the gear to rotate through the output rod and the sliding rod, so that the cleaning device can move and rotate by itself without manual rotation of the cleaning tube, making cleaning more time-saving and labor-saving.

[0017] 2. In this utility model, by opening regular-shaped holes in the cleaning pipe, water can better enter the inner wall, and by installing spiral brush strips on the outer wall of the cleaning pipe, the pipe can be cleaned more thoroughly through cooperation with the holes.

[0023] 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.

[0024] Reference Figure 1 - Figure 3This utility model provides an embodiment of a shell-and-tube heat exchanger cleaning device, including a first mounting plate 1. A groove 14 is provided on the front side of the first mounting plate 1 for mounting a sliding rod 13. The sliding rod 13 is slidably connected within the groove 14 for connection between a rack 11 and the first mounting plate 1. A rack 11 is fixedly connected to the front side of the sliding rod 13. Multiple gears 4 mesh with the lower side of the rack 11. Multiple cleaning pipes 6 are rotatably connected through the middle of the first mounting plate 1. The cleaning pipes 6 are fixedly connected to the gears 4. This device can clean the inner walls of multiple pipes at once, saving time. Multiple cleaning pipes 6 are rotatably connected to the front end of a rotating joint 12, and the cleaning pipes 6 are connected to the rotating joint 12. During cleaning, water can be introduced through the rotating joint 12. A second mounting plate 2 is fixedly connected to the upper part of the first mounting plate 1 to cooperate in installing the cylinder 3. The cylinder 3 is installed on the front side of the second mounting plate 2 to provide rotational power for the cleaning pipes 6. A sliding rod 10 is fixedly connected to the left side of the cylinder 3 through an output rod. The lower end of the sliding rod 10 is fixedly connected to the rack 11 to drive the rack 11 to push and pull.

[0025] The front of the No. 1 mounting plate 1 is fixedly connected to a handle 5, which makes it easier for users to operate and move the cleaning equipment during cleaning. The cleaning pipe 6 has multiple holes 61 for water to enter when cleaning the inner wall of the pipe. The multiple holes 61 are arranged in a regular manner so that water can enter the inner wall when it flows through the cleaning pipe 6 for better cleaning. The outer wall of the cleaning pipe 6 is equipped with a brush 62, which is made of wear-resistant and corrosion-resistant nylon. The brush 62 is spiral-shaped. When the equipment is running and cleaning, the gear 4 drives the cleaning pipe 6 to rotate so that the brush 62 can clean the inner wall of the pipe evenly.

[0026] Working principle: When using the cleaning device, the user can lift the device using handle 5, align the cleaning tube 6 with the pipe to be cleaned, connect the high-pressure water pump to the rotary joint 12 via a hose connector, and then open the cylinder 3. The cylinder 3 will drive the sliding rod 10 to move left and right. Since the bottom end of the sliding rod 10 is connected to the rack 11, the sliding rod 10 will drive the rack 11 to move left and right. The gear 4 will be driven to rotate by the movement of the rack 11. Because the cleaning tube 6 is connected through the middle of the gear 4, the cleaning tube 6 will rotate. Since the cleaning tube 6 has a large number of regular holes 61 and is equipped with spiral brush strips 62 on the outside, water will enter the cleaning tube 6 after the high-pressure water pump is turned on, and then enter the inner wall of the pipe through the holes 61. As the cleaning tube 6 rotates, the spiral brush strips 62 will also rotate and clean the inner wall of the pipe. The holes 61 and the brush strips 62 work together to clean the heat exchanger.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
