Description

Technical Field

[0001] This utility model relates to the field of closed-loop cooling tower technology, specifically a sealed maintenance door for an integrated closed-loop cooling tower unit. Background Technology

[0002] A closed-circuit cooling tower (also called an evaporative air cooler or closed-loop cooling tower) places a tubular heat exchanger inside the tower. Cooling is achieved through heat exchange between circulating air, spray water, and circulating water. Because of the closed-loop circulation, it ensures water quality remains uncontaminated, effectively protecting the main equipment and extending its service life. When the outside temperature is low, the spray water system can be shut off, saving water. With the implementation of national energy conservation and emission reduction policies and the increasing scarcity of water resources, closed-circuit cooling towers have been widely used in industries such as metallurgy, aviation, power, chemical, machinery, petroleum, food, plastics, and rubber in recent years.

[0003] To facilitate the maintenance of closed-circuit cooling tower units, sealed access doors are often installed. Existing sealed access doors are installed using numerous bolts, which is not only time-consuming but also prone to deformation at different locations if the bolts are installed with varying torques. Excessive deformation can degrade the sealing effect of the access door. Therefore, to solve these problems, we propose a sealed access door for closed-circuit cooling tower units. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a sealed maintenance door for an integrated closed cooling tower.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sealed maintenance door for an integrated closed-circuit cooling tower includes a door frame. A retaining ring is connected to the inner wall of the door frame, and a sealing slot is provided on the retaining ring. Positioning grooves are provided on both the top and bottom sides of the inner wall of the door frame. A support block is connected to one end of the inner wall of the positioning groove. A sealed door is placed on one end of the inner wall of the door frame. Two mounting components are installed on both sides of one end of the sealed door and both sides of one end of the door frame. A retaining ring is connected to the other end of the sealed door, and a sealing rubber ring is embedded at one end of the retaining ring. Positioning blocks are connected to both the top and bottom sides of the sealed door. The mounting components include three U-shaped positioning blocks and two bearing blocks. One end of each bearing block is connected to the sealed door. Damping sleeves are connected to opposite sides of each of the two bearing blocks. Damping rods are installed inside the damping sleeves. Rotating shafts are connected to opposite sides of the two damping rods.

[0007] Preferably, the sealed door is inlaid with transparent tempered glass, the outside of the sealed door is in contact with the inner wall of the door frame, and one end of the sealed door and one end of the door frame are on the same plane.

[0008] Preferably, the sealing ring extends into the interior of the sealing slot on the side away from the second retaining ring, and the door frame is connected to the closed-loop cooling tower unit on the side away from the sealing door.

[0009] Preferably, the positioning block extends into the positioning groove from the side away from the sealing door and is suspended outside the support block, and the positioning block has a suspension hole for use with the support block.

[0010] Preferably, one end of the U-shaped positioning block is connected to the door frame, a rotating screw is rotatably connected at the center of the side of the two rotating shafts that are far apart, and guide rods are connected to the top and bottom of the side of the two rotating shafts that are far apart. The rotating screw and the guide rods pass through the U-shaped positioning block on the side of the side of the rotating shafts that are far apart.

[0011] Preferably, a rotating hole is provided at the center of the two rotating shafts on opposite sides, and the outer side of the rotating screw is movably connected to the inner wall of the rotating hole through a bearing.

[0012] Preferably, the rotating screw is threaded with a rotating cylinder, the guide rod is slidably fitted with a guide block, and the top and bottom of the rotating cylinder are connected to a connecting plate, with the side of the connecting plate away from the rotating cylinder connected to the guide block.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention utilizes the installation components. Under the action of force, the rotating connecting plate rotates the shaft, causing the damping rod to rotate. This ultimately causes the rotating screw and guide rod to lock into the groove of the U-shaped positioning block. The forward rotation of the rotating screw causes the rotating screw cylinder to move towards the U-shaped positioning block. Under the action of the connecting plate, the guide block also moves towards the U-shaped positioning block. Ultimately, the rotating screw cylinder and guide block apply pressure to the U-shaped positioning block, preventing the rotating screw and guide rod from disengaging from the U-shaped positioning block, thus completing the installation of the sealing door.

A damping rod 46 is installed inside the damping sleeve 410. A rotating shaft 41 is connected to the opposite side of the two damping rods 46.

[0024] As a technical optimization of this utility model, a transparent tempered glass 3 is embedded in the sealing door 2, the outside of the sealing door 2 is in contact with the inner wall of the door frame 1, and one end of the sealing door 2 and one end of the door frame 1 are on the same plane; through the transparent tempered glass 3, it is convenient to observe the internal situation of the closed cooling tower integrated machine through the sealing door 2.

[0025] As a technical optimization of this utility model, the side of the sealing ring 11 away from the second retaining ring 10 extends into the interior of the sealing slot 7, and the side of the door frame 1 away from the sealing door 2 is connected to the closed cooling tower integrated machine; through the cooperation of the sealing slot 7 and the sealing ring 11, the connection between the second retaining ring 10 and the first retaining ring 6 can be sealed; one end of the second retaining ring 10 is in contact with the first retaining ring 6.

[0026] As a technical optimization of this utility model, the side of the positioning block 9 away from the sealing door 2 extends into the interior of the positioning groove 8 and is suspended on the outside of the support block 5. The positioning block 9 is provided with a hanging hole 12 that cooperates with the support block 5. The hanging hole 12 makes it convenient for the positioning block 9 to be suspended on the support block 5.

[0027] As a technical optimization of this utility model, one end of the U-shaped positioning block 44 is connected to the door frame 1, and a rotating screw 42 is rotatably connected at the center of the side of the two rotating shafts 41 that are far apart. Guide rods 47 are connected to the top and bottom of the side of the two rotating shafts 41 that are far apart. The side of the rotating screw 42 and the guide rod 47 that are far apart from the rotating shafts 41 both pass through the U-shaped positioning block 44.

[0028] As a technical optimization of this utility model, a rotating hole 411 is provided at the center of the two rotating shafts 41 on the side furthest apart. The outer side of the rotating screw 42 is movably connected to the inner wall of the rotating hole 411 through a bearing. The rotating hole 411 facilitates the rotation of the rotating screw 42.
