Description

Technical Field

[0001] The utility model belongs to the technical field of tubular condenser filtering equipment, and in particular relates to a high-efficiency corrosion-resistant tubular condenser filtering device. Background Art

[0002] Shell and tube condensers are categorized by material: carbon steel, stainless steel, and a combination of carbon steel and stainless steel. They are also classified by form factor into fixed tube sheet, floating head, and U-tube heat exchangers. They are coated or electroplated with an anti-corrosion coating to provide corrosion resistance.

[0003] When water is directly injected into the anti-corrosion shell and tube condenser, the water contains certain impurities, which are easily accumulated inside the high-efficiency anti-corrosion shell and tube condenser. When replacing the filter element of a conventional filter, it is necessary to turn off the water valve first and then replace the filter element, which makes it more troublesome to replace the filter element of the conventional anti-corrosion shell and tube condenser.

[0004] To this end, we proposed a high-efficiency anti-corrosion shell and tube condenser filtration device to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the problem that it is troublesome to replace the filter element of the conventional anti-corrosion shell and tube condenser, and proposes a high-efficiency anti-corrosion shell and tube condenser filtering device.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A high-efficiency, corrosion-resistant shell-and-tube condenser filtering device comprises a water injection nozzle, a shell having a threaded seal installed at the lower portion of the water injection nozzle, a one-way plug movably installed inside the water injection nozzle, a frame fixedly connected to the interior of the shell, a filter cloth sleeve on the frame, and the lower end of the frame pressing against the lower end of the one-way plug through the filter cloth sleeve. The lower end of the frame is connected to the water injection port pipe of the target high-efficiency, corrosion-resistant shell-and-tube condenser, and the water injection nozzle is connected to the water injection pipe; the one-way plug is pushed downward by the frame to keep it open, and after water enters the water injection nozzle, it enters the shell through the water injection nozzle, allowing the water to pass through the filter cloth sleeve and enter the frame, where it is filtered by the filter cloth sleeve, and the filtered water is discharged into the high-efficiency, corrosion-resistant shell-and-tube condenser through the frame; when the water source is not turned off, the shell is unscrewed, causing the lower end of the one-way plug to lose support, and the water pressure acts downward on the one-way plug, causing the one-way plug to block the lower portion of the water injection nozzle, thereby automatically shutting off the water supply when the water source is removed.

[0008] Preferably, the water injection nozzle includes a docking nozzle, a water guide shell, and a first hexagonal rotating ring. The lower end of the water guide shell is evenly hollowed out to form a water inlet. The lower end of the docking nozzle is fixedly connected to the upper end of the water guide shell, and the first hexagonal rotating ring is fixedly connected to the outside of the water guide shell. The water injection nozzle is connected to an external water injection pipe through the docking nozzle. Water enters the water guide shell through the docking nozzle and enters the outer shell through the water inlet, making it convenient to connect the water injection nozzle to the water pipe.

[0009] Preferably, the water injection nozzle further comprises a first anti-slip ring, which is evenly fixedly connected to the outside of the docking nozzle. The first anti-slip ring is used to increase the friction between the water injection nozzle and the water pipe, thereby improving the firmness between the water injection nozzle and the water pipe.

[0010] Preferably, the one-way plug comprises a plug body, a sealing ring, a sliding rod, and a limiting plate, wherein the plug body is fixedly connected to the upper end of the sliding rod, the sealing ring is fixedly connected to the lower end of the plug body, and the limiting plate is fixedly connected to the lower end of the sliding rod. When the lower end of the limiting plate loses support, water pressure acts on the upper end of the plug body, causing the plug body to move downward, thereby pressing the sealing ring against the interior of the water guide housing, thereby facilitating the one-way plug to automatically close the lower portion of the water injection nozzle.

[0011] Preferably, the housing includes a threaded ring, a second hexagonal rotating ring, and a housing, wherein the second hexagonal rotating ring is fixedly connected to the outside of the threaded ring, and the threaded ring is fixedly connected to the upper end of the housing. A wrench is used to tighten the first hexagonal rotating ring, and another wrench is used to tighten the second hexagonal rotating ring. The threaded ring is then removed from the lower portion of the water guide housing through the action of the sealing ring, and then re-screwed onto the water guide housing, thereby facilitating installation or removal of the housing.

[0012] Preferably, the skeleton comprises a top block, a grid and a butt joint, wherein the top block is fixedly connected to the upper end of the grid, and the butt joint facilitates connection to the water inlet pipe of the high-efficiency anti-corrosion shell-and-tube condenser.

[0013] Preferably, the frame further comprises a second anti-slip ring, which is evenly fixedly connected to the lower portion of the butt joint, and is used to increase the friction between the butt joint and the water inlet pipe of the high-efficiency anti-corrosion shell-and-tube condenser.

[0014] In summary, the technical effects and advantages of the utility model are:

[0015] 1. Connect the lower end of the skeleton to the water injection pipe of the target high-efficiency anti-corrosion shell and tube condenser, and connect the water injection nozzle to the water injection pipe; use the skeleton to push the one-way plug downward to keep the one-way plug open. After water enters the water injection nozzle, it enters the shell through the water injection nozzle, allowing the water to pass through the filter cloth cover into the skeleton and filter it with the filter cloth cover. The filtered water is discharged into the high-efficiency anti-corrosion shell and tube condenser through the skeleton; when the water source is not turned off, unscrew the shell to make the lower end of the one-way plug lose support, and use water pressure to act downward on the one-way plug to block the lower part of the water injection nozzle, so that the water supply is automatically cut off during replacement. There is no need to worry about the status of the water valve before replacement, which improves replacement efficiency.

[0016] 2. The water injection nozzle is connected to the water injection pipe through the docking nozzle. Water enters the water guide shell through the docking nozzle and enters the outer shell through the water opening, making it convenient to connect the water injection nozzle to the water pipe.

[0017] 3. When the lower end of the limit plate loses its support, the water pressure is used to act on the upper end of the plug body, causing the plug body to move downward, thereby pressing the sealing ring inside the water guide shell, making it convenient for the one-way plug to automatically close the lower part of the water injection nozzle.

[0018] 4. Use a wrench to tighten the first hexagonal rotating ring, and then use another wrench to tighten the second hexagonal rotating ring. Through the sealing ring, act on the threaded ring and unscrew the threaded ring from the bottom of the water guide shell. Conversely, screw the threaded ring back on the water guide shell to facilitate the installation or removal of the shell. BRIEF DESCRIPTION OF THE DRAWINGS
