Description

Technical Field

[0001] This utility model relates to a cooling tower sewage discharge structure, belonging to the field of cooling towers. Background Technology

[0002] Cooling towers are used for heat dissipation in circulating water systems. During operation, water evaporation and the entry of dust and debris can lead to an increase in the concentration of impurities and salts in the circulating water, affecting the normal operation of the system. A small amount of wastewater is continuously discharged through a drain valve installed in the circulating water system, while fresh water is added to maintain stable water quality. Connecting pipes are installed on the surface of the cooling tower's bottom trough using flanges and bolts. These connecting pipes are equipped with shut-off valves and drain valves. The former connects to the circulating water pump to ensure normal water circulation, while the latter opens after the shut-off valve is closed, forming an independent drain channel for efficient wastewater discharge. However, the connecting bolts, constantly exposed to humid air and water mist, are highly susceptible to oxidation and corrosion. Over time, corrosion not only weakens the bolt's tightening performance but can also cause the threads to seize, greatly increasing the difficulty of disassembling and replacing the connecting pipes. This difficulty in disassembly may even affect the maintenance efficiency and lifespan of the entire cooling tower system. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a cooling tower sewage discharge structure to solve the problems mentioned in the background technology. This utility model optimizes and improves the connection between the connecting pipe and the bottom trough of the cooling tower, reducing the difficulty of disassembling the connection between the connecting pipe and the bottom trough of the cooling tower later.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cooling tower sewage discharge structure, comprising:

[0005] A cooling tower bottom trough, wherein a protrusion is installed on the outer surface of the cooling tower bottom trough, and a flange is installed on the outer surface of the protrusion, the flange being connected to a water flow channel formed inside the protrusion;

[0006] A connecting pipe is provided on the side of the flange away from the protrusion. A shut-off valve for connecting a circulating water pump is installed at the end of the connecting pipe away from the flange. A drain valve is installed at the middle of the outer surface of the connecting pipe. A mating ring that mates with the flange is installed at the end of the connecting pipe away from the shut-off valve.

[0007] A pressure ring is provided on the side of the mating ring away from the flange. Multiple plug rods are evenly installed on the side of the pressure ring facing the mating ring, and the plug rods pass through the mating ring and the flange.

[0008] Connecting plates: Two connecting plates are symmetrically installed on the annular side of the pressure ring, and the connecting plates have a Z-shaped structure;

[0009] The thickened portion has two thickened portions symmetrically arranged about the flange installed on the outer surface of the protrusion, and the connecting plate is connected to the thickened portions by screws.

[0010] Furthermore, the thickened portion includes:

[0011] The connector has two symmetrically arranged connectors about the flange mounted on the outer surface of the protrusion. A support plate is mounted on the side of the connector away from the protrusion. The end of the support plate away from the connector contacts the side of the connecting plate mounting screw. Both connectors have connector grooves on their opposite sides. Both connectors have notches on the side away from the protrusion. The notches communicate with the connector grooves. The opening ends of the two notches face opposite directions.

[0012] The plug-in block is installed in the plug-in slot. One side of the plug-in block has a screw hole that mates with a screw. The side of the connecting plate facing the notch has a small hole. One end of the screw passes through the small hole and the notch and is threaded into the screw hole.

[0013] Furthermore, the cross-section of the plug block is rectangular, and the cross-section of the plug slot is rectangular.

[0014] Furthermore, a chassis is provided on the lower side of the connecting pipe, and the drain valve and shut-off valve are both located directly above the chassis. A pipe joint for connecting the drain pipe is installed on one side of the chassis, and two hanging plates are installed at the upper part of one side of the chassis. The screw passes through the hanging plate and the connecting plate and connects to the thickened part.

[0015] Furthermore, a branch pipe is installed at the middle of the outer surface of the connecting pipe, and the end of the straight pipe away from the connecting pipe is connected to the drain valve.

[0016] Furthermore, one side of the flange is provided with a plurality of first pin holes at equal intervals in an annular shape, and one side of the mating ring is provided with a plurality of second pin holes at equal intervals in an annular shape that mate with the first pin holes. The insertion rod is inserted into the channel formed by the first pin holes and the second pin holes, and a sealing gasket is provided between the mating ring and the flange.

[0017] Furthermore, a cooling tower cylinder is provided directly above the cooling tower bottom trough, and multiple columns are installed in a ring at equal intervals between the cooling tower cylinder and the cooling tower bottom trough, with multiple arc-shaped rods arranged vertically at equal intervals between adjacent columns.

[0018] Furthermore, the bottom of the cooling tower trough is provided with multiple supports installed in a ring at equal intervals, and the supports and the cooling tower trough are integrally formed.

[0019] The beneficial effects of this utility model are:

[0020] 1. Insert the plug rod on the pressure ring through the mating ring and flange, then insert the plug block into the plug groove. Screw one end of the screw through the connecting plate and notch and into the screw hole to assemble the connecting pipe and the protrusion. With the support of the support plate, part of the screw is exposed. When the screw cannot be disassembled normally due to rust, use the space formed by the plug seat, support plate and connecting plate to cut off the screw. Then remove the plug block with part of the screw remaining from the plug groove and replace it. This optimizes and improves the connection between the connecting pipe and the cooling tower bottom tank, reducing the difficulty of disassembling the connection between the connecting pipe and the cooling tower bottom tank later.

[0021] 2. After the screw passes through the hanging plate and connecting plate, it is threaded to the plug block in the plug slot. This allows the screw to restrict the position of the chassis, thereby reducing the amount of screws used. When the shut-off valve and drain valve leak water due to seal failure, the leaked water drips into the chassis. Subsequently, the leaked water flows into the collection container through the channel formed by the pipe joint and the drain pipe, preventing the leaked water from dripping and flowing randomly.

Detailed Implementation

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] Please see Figure 1 and Figure 3 This utility model provides a technical solution: a cooling tower drainage structure, including a cooling tower bottom trough 3, a protrusion 6 installed on the outer surface of the cooling tower bottom trough 3, a flange 20 installed on the outer surface of the protrusion 6, the flange 20 communicating with the water flow channel formed inside the protrusion 6; a cooling tower cylinder 1 is provided directly above the cooling tower bottom trough 3, and multiple columns 4 are installed in a ring at equal intervals between the cooling tower cylinder 1 and the cooling tower bottom trough 3, and multiple arc-shaped rods 2 arranged vertically at equal intervals are installed between two adjacent columns 4. The arc-shaped rods 2 and the columns 4 serve to connect the cooling tower bottom trough 3 and the cooling tower cylinder 1, and at the same time provide a channel for air circulation. Multiple support legs 5 are installed in a ring at equal intervals at the bottom of the cooling tower bottom trough 3. The support legs 5 are integrally formed with the cooling tower bottom trough 3, and the support legs 5 provide balanced support for the cooling tower bottom trough 3.

[0030] See Figures 1-4 A connecting pipe 11 is provided on the side of the flange 20 away from the protrusion 6. A shut-off valve 8 for connecting a circulating water pump is installed at the end of the connecting pipe 11 away from the flange 20. A branch pipe 19 is installed at the middle of the outer surface of the connecting pipe 11. A drain valve 9 is installed at the end of the branch pipe 19 away from the connecting pipe 11. A mating ring 27 that mates with the flange 20 is installed at the end of the connecting pipe 11 away from the shut-off valve 8. A sealing gasket is provided between the mating ring 27 and the flange 20. The side of the mating ring 27 away from the flange 20 A pressure ring 17 is provided, and multiple plug rods 26 are evenly installed on the side of the pressure ring 17 facing the mating ring 27. The plug rods 26 pass through the mating ring 27 and the flange 20. The flange 20 has multiple first pin holes 21 equidistantly arranged in a ring on one side, and the mating ring 27 has multiple second pin holes 25 equidistantly arranged in a ring on one side, which cooperate with the first pin holes 21. The plug rods 26 are inserted into the channel formed by the first pin holes 21 and the second pin holes 25, so that the relative position of the flange 20 and the mating ring 27 remains unchanged.

[0031] See Figures 1-4Two connecting plates 18 are symmetrically installed on the annular side of the pressure ring 17. The connecting plates 18 have a Z-shaped structure. Two plug-in seats 15 are symmetrically arranged about the flange 20 on the outer surface of the protrusion 6. A support plate 16 is installed on the side of the plug-in seat 15 away from the protrusion 6. The end of the support plate 16 away from the plug-in seat 15 is in contact with the side of the connecting plate 18 where the screw 13 is installed. Both plug-in seats 15 have plug-in grooves 22 on their opposite sides. The cross-section of the plug-in grooves 22 is rectangular. Both plug-in seats 15 have notches 24 on their opposite sides from the protrusion 6. The notches 24 communicate with the plug-in grooves 22. The opening ends of the two notches 24 face opposite directions. A plug-in block 14 is inserted into the plug-in groove 22. The cross-section of the plug-in block 14 is rectangular. One side of the plug-in block 14 has a screw hole 23 that mates with the screw 13. The side of the connecting plate 18 facing the notch 24 has a small hole. One end of the screw 13 passes through the small hole and the notch 24 and is threaded into the screw hole 23. When assembling the connecting pipe 11 and the protrusion 6 of the cooling tower bottom groove 3, first pass the plug rod 26 on the pressure ring 17 through the pin holes on the mating ring 27 and the flange 20 in sequence to complete the initial positioning. Next, insert the plug block 14 into the plug groove 22 of the plug seat 15, aligning the small hole on the connecting plate 18, the notch 24 of the plug seat 15, and the screw hole 23 of the plug block 14. Then, pass one end of the screw 13 through the connecting plate 18 and the notch 24, and screw it into the screw hole 23 of the plug block 14 to fix the pressure ring 17, the mating ring 27, and the flange 20, thus achieving a stable assembly of the connecting pipe 11 and the protrusion 6.

[0032] Supported by the support plate 16, only a portion of the screw 13 is exposed on the outside of the connecting plate 18. When the screw 13 becomes corroded due to long-term exposure to a humid environment, making normal disassembly impossible, the corroded screw 13 can be cut off using the operating space formed between the plug-in connector 15, the support plate 16, and the connecting plate 18. After cutting, simply remove the plug-in block 14 with the remaining screw 13 from the plug-in slot 22 and replace it with a new plug-in block 14 to quickly complete the disassembly and repair of the connection. This design replaces the traditional all-bolted connection with a modular plug-in structure, moving the easily corroded screw 13 from the dense flange connection area to an easily accessible external space. Furthermore, the replaceability of the plug-in block 14 significantly reduces the disassembly difficulty caused by screw corrosion, improving the ease of maintenance and reliability of the cooling tower's drainage structure.

[0033] See Figure 1 and Figure 2A base plate 7 is located below the connecting pipe 11. The drain valve 9 and shut-off valve 8 are both positioned directly above the base plate 7. A pipe connector 10 for connecting the inlet / outlet pipe is installed on one side of the base plate 7. Two hanging plates 12 are installed at the upper part of one side of the base plate 7. Screws 13 pass through the hanging plates 12 and connecting plates 18 and connect to the plug-in socket 15. By threading the screws 13 through the hanging plates 12 and connecting plates 18 to the plug-in block 14 in the plug-in slot 22, the position of the base plate 7 is effectively restricted. This design reduces the number of screws 13 used while ensuring the base plate 7 is securely installed. When leakage occurs due to sealing failure at the shut-off valve 8 or drain valve 9, the dripping water will collect in the base plate 7 and then flow orderly into the collection container through the channel formed by the pipe connector 10 and the inlet / outlet pipe. This design prevents leaked water from dripping and flowing randomly, maintaining the cleanliness of the surrounding environment and effectively collecting leaked liquid for subsequent treatment, thus improving the system's reliability and environmental friendliness.
