Technical Field

[0001] This utility model relates to the field of condenser technology, specifically to a condenser for descaling methyl vinyl silicone rubber. Background Technology

[0002] In the production of methyl vinyl silicone rubber, the removal of low-molecular-weight volatiles, or "low-molecular-weight removal" for short, is a key process. During this process, high-temperature silicon-containing vapors need to be rapidly cooled and recovered by a condenser to ensure product purity and production efficiency. In the long-term operation of existing condensers, minerals such as calcium and magnesium in the cooling water continuously precipitate on the high-temperature pipe walls, forming a dense scale layer that adheres to the outer wall of the condenser pipes, greatly affecting heat exchange efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a condenser for the removal of methyl vinyl silicone rubber, which can clean the condensation pipes in a timely manner and greatly improve the heat exchange effect.

[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a condenser for removing methyl vinyl silicone rubber, comprising a base, a condenser housing fixedly connected to the upper end of the base, a refrigerant input pipe fixedly connected to one side of the condenser housing, a vertically arranged input guide pipe fixedly connected to one end of the refrigerant input pipe extending into the condenser housing, at least one serpentine condensing coil fixedly connected to one side of the input guide pipe, an output guide pipe fixedly connected to the other end of the serpentine condensing coil, and a refrigerant output pipe extending out of the condenser housing fixedly connected to one side of the output guide pipe; the serpentine cooling coil includes at least one vertically arranged horizontal condensing pipe, the upper and lower horizontal condensing pipes being connected end to end by a C-shaped bend, at least one cleaning scraper slidably connected inside the condenser housing, the cleaning scraper having cleaning scraping holes that cooperate with the horizontal condensing pipes, a connecting frame fixedly connected between adjacent cleaning scrapers, and a reciprocating adjustment mechanism for driving the cleaning scraper to slide left and right inside the condenser housing.

[0005] As an improvement, a spray pump is fixedly connected to one side of the condenser housing, and a water supply pipe extending above the serpentine condenser coil is fixedly connected to the output end of the spray pump. A shaped spray pipe is fixedly connected to one end of the water supply pipe inside the condenser housing, and the bottom surface of the shaped spray pipe is provided with at least one evenly arranged spray head.

[0006] As an improvement, a fan is fixedly connected to the upper end of the condenser housing, and air intake grilles are provided on both sides of the lower end of the condenser housing.

[0007] As an improvement, the reciprocating adjustment mechanism includes an adjustment rod fixedly connected to one side of the cleaning scraper, an adjustment frame fixedly connected to one end of the adjustment rod extending to the outside of the condenser housing, a mounting bracket fixedly connected to the outer wall of the condenser housing, a rocker arm rotatably connected to one side of the mounting bracket, an adjustment block slidably connected to one end of the rocker arm, and a motor for driving the rocker arm to rotate fixedly connected to one side of the mounting bracket.

[0008] As an improvement, a spring sleeved on the outer wall of the adjusting rod is fixedly connected between the inner wall of the condenser casing and the adjacent cleaning scraper.

[0009] The advantages of this invention compared to existing technologies are as follows: This invention creatively incorporates a sliding cleaning scraper inside the condenser housing, with cleaning holes that closely engage with the horizontal condenser tubes of the serpentine condenser coil. Driven by a reciprocating adjustment mechanism, the cleaning scraper slides left and right, directly and physically removing scale adhering to the outer wall of the horizontal condenser tubes.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] like Figures 1 to 4 As shown, a condenser for removing methyl vinyl silicone rubber includes a base, a condenser housing 1 fixedly connected to the upper end of the base, a fan 2 fixedly connected to the upper end of the condenser housing 1, air inlet grilles 3 on both sides of the lower end of the condenser housing 1, a refrigerant input pipe 7 fixedly connected to one side of the condenser housing 1, a vertically arranged input guide pipe 8 fixedly connected to one end of the refrigerant input pipe 7 extending into the condenser housing 1, at least one serpentine condensing coil 11 fixedly connected to one side of the input guide pipe 8, an output guide pipe 10 fixedly connected to the other end of the serpentine condensing coil 11, and a refrigerant output pipe 9 fixedly connected to one side of the output guide pipe 10 extending outside the condenser housing 1.

[0017] The serpentine cooling coil includes at least one vertically arranged horizontal condenser tube 21, which is connected end to end by a C-shaped bend 22. At least one cleaning scraper 12 is slidably connected inside the condenser housing 1. The cleaning scraper 12 is provided with cleaning scraping holes 13 that cooperate with the horizontal condenser tube 21. A connecting frame 14 is fixedly connected between adjacent cleaning scrapers 12. The condenser housing 1 is provided with a reciprocating adjustment mechanism that drives the cleaning scraper 12 to slide left and right.

[0018] A spray pump 4 is fixedly connected to one side of the condenser housing 1. A water supply pipe 5 extending above the serpentine condenser coil 11 is fixedly connected to the output end of the spray pump 4. A shaped spray pipe 6 is fixedly connected to one end of the water supply pipe 5 inside the condenser housing 1. The bottom surface of the shaped spray pipe 6 is provided with at least one evenly arranged spray head.

[0019] The reciprocating adjustment mechanism includes an adjustment rod 15 fixedly connected to one side of the cleaning scraper 12. The adjustment rod 15 extends to the outside of the condenser housing 1 and is fixedly connected to an adjustment frame 16. An installation bracket 20 is fixedly connected to the outer wall of the condenser housing 1. A rocker arm 18 is rotatably connected to one side of the installation bracket 20. An adjustment block 19 slidably connected to one end of the rocker arm 18 is rotatably connected to the adjustment block 19 inside the adjustment frame 16. A motor 17 that drives the rocker arm 18 to rotate is fixedly connected to one side of the installation bracket 20.

[0020] A spring 23, sleeved on the outer wall of the adjusting rod 15, is fixedly connected between the inner wall of the condenser housing 1 and the adjacent cleaning scraper 12.

[0021] In practical use, the refrigerant from the de-siliconization process is connected to the condenser inlet through the refrigerant input pipe 7, the water inlet of the spray pump 4 is connected to the water source, the power supply is turned on to the motor 17 and the fan 2, and the fan 2 and the spray pump 4 are started. The high-temperature silicon-containing vapor from the de-siliconization process enters the input guide pipe 8 through the process steam inlet pipe and flows through the inside of the serpentine condenser coil 11. The spray water is pressurized by the spray pump 4 and transported to the F-shaped spray pipe 6 through the water supply pipe 5. It is evenly sprayed by the spray head to cover the outer surface of the serpentine condenser coil 11. The fan 2 works and draws in ambient air from the air intake grilles 3 on both sides of the lower end of the condenser box 1. The forced airflow flows upward through the surface of the serpentine condenser coil 11 that is wetted by the spray water.

[0022] High-temperature refrigerant flows inside the serpentine condenser coil 11, transferring its heat through the coil wall to the spray water film covering the outside of the coil. Air flows over the moist coil surface, causing the spray water film to evaporate. The evaporation process absorbs a large amount of latent heat of vaporization, thus efficiently carrying away the heat of the vapor inside the coil and condensing it into liquid. Some of the spray water that fails to evaporate falls back to the bottom of the casing. The air discharged by the fan 2 is hot and humid air, which is discharged from the top of the casing. Spraying is both a necessary step in cooling and an auxiliary means of cleaning. During normal operation, the spray system operates continuously or intermittently to maintain cooling. When enhanced cleaning is required, the spray water volume can be maintained or increased. When a decrease in heat exchange efficiency is detected or scale removal from the pipe walls is required according to a preset program, the drive motor 17 is activated. The motor 17 drives the rocker arm 18 to rotate, and the adjusting block 19 at the end of the rocker arm 18 slides within the adjusting frame 16, thereby driving the adjusting frame 16 and the adjusting rod 15 to perform reciprocating linear motion. The adjusting rod 15 drives the cleaning scraper 12 connected to it and other scrapers connected through the connecting frame 14 to slide left and right within the condenser housing 1. When the cleaning scraper 12 slides, the edge of its cleaning scraping hole 13 is in close contact with and relative to the outer surface of the condenser horizontal tube 21 of the serpentine condenser coil 11, effectively scraping off the scale adhering to the pipe wall using mechanical force. The scraped scale debris is washed away by the spray water or naturally settles to the bottom of the condenser housing 1. The bottom of the housing should be equipped with a drain port for periodically or automatically discharging wastewater and concentrated circulating water containing scale debris.
