Description

Technical Field

[0001] This utility model relates to a multi-seal structure for a cooling tower water collection tank, belonging to the field of cooling tower water collection tank sealing technology. Background Technology

[0002] With the expansion of industrial production scale and the upgrading of equipment quality requirements, all-steel cooling towers, with their advantages of high structural strength, excellent corrosion resistance, short installation cycle, and adaptability to complex working conditions, have gradually replaced traditional concrete and fiberglass cooling towers, becoming the core equipment of circulating water cooling systems in industries such as chemical, power, metallurgy, and pharmaceutical. Among these components, the water collection tank, as a key water storage component of the cooling tower, primarily functions to collect the circulating cooling water falling from the packing layer, ensuring a stable flow of water into the circulating water pump. Its sealing performance directly determines the operating efficiency and maintenance costs of the cooling tower; any leakage in the base plate will directly affect the stability of the entire cooling system.

[0003] Currently, the water collection tank of all-steel cooling towers is generally formed by splicing multiple metal steel plates. The conventional splicing process is as follows: the edges of two adjacent steel plates are overlapped, bolt holes are opened at intervals in the overlap area, and stainless steel bolts are used to achieve mechanical fastening. At the same time, an elastic sealing strip is sandwiched between the overlap surfaces of the two steel plates to prevent water leakage. For example, Chinese utility model patent application number 2023210570400 discloses a cooling tower water storage basin. The sheet metal structure layer of the water storage basin is composed of multiple sheet metal plates spliced ​​together and connected and fixed by bolts that vertically penetrate the sheet metal plates. In practical applications, this conventional splicing structure has significant defects: First, the processing precision of steel plates is difficult to be completely uniform, and the overlapping surfaces are prone to forming tiny gaps due to flatness deviations, making it impossible for the sealing strip to fit completely; Second, the circulating cooling water is in a temperature range of 30-50℃ for a long time, and some industrial circulating water contains trace amounts of corrosive media, which will accelerate the aging and deformation of the sealing strip, leading to a gradual decline in sealing performance; Third, bolt perforation will damage the integrity of the steel plate, and the thread gap between the bolt and the hole wall is prone to forming a water seepage channel. Even with the use of sealing rings to assist in sealing, it is difficult to prevent water from seeping along the thread gap. The aforementioned problems ultimately lead to frequent leaks at the steel plate joints and bolt holes during the operation of the water collection tank. This not only reduces customer trust in the equipment brand but also requires additional manpower and resources for on-site repairs, increasing operation and maintenance costs. More seriously, long-term leaks can corrode the steel structure support below the water collection tank, shortening the overall lifespan of the cooling tower. In low-temperature winter environments, the leaking water may even freeze, potentially causing structural safety hazards. Therefore, it is urgent to optimize and improve the splicing and sealing structure of the water collection tank to solve the leakage problem. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a multi-seal structure for cooling tower water collection tanks, thereby improving sealing performance and effectively preventing water leakage from the bottom plate of the water collection tank.

[0005] The technical solution of this utility model is: a multi-seal structure for a cooling tower water collection tank, including a water collection tank bottom plate assembly, the water collection tank bottom plate assembly including a plurality of adjacent bottom plate units, the bottom plate unit including a bottom plate body and a connecting structure a and a connecting structure b symmetrically arranged at both ends of the bottom plate body, the connecting structure a and the connecting structure b of adjacent bottom plate units are sealed and connected by a sealing structure. The connecting structure a includes a connecting plate a that is vertically connected to the base plate body, and a reinforcing rib a that is vertically connected to the bottom of the connecting plate a; The connecting structure b includes a connecting plate b that is vertically connected to the base plate body, and a reinforcing rib b that is vertically connected to the bottom of the connecting plate b.

[0006] The sealing structure includes a rubber sealing strip, a bolt assembly, structural sealant, and waterproof tape. The rubber sealing strip is disposed between connecting plate a and connecting plate b. The bolts of the bolt assembly pass through the rubber sealing strip, connecting plate a, and connecting plate b and are tightened with nuts to ensure a tight seal between the two sides of the rubber sealing strip and connecting plate a and connecting plate b. Structural sealant is provided at the top of the rubber sealing strip and is adhered to the top between connecting plate a and connecting plate b. Waterproof tape is provided above the structural sealant and is sealed and adhered at both ends to the base plate body of the adjacent base plate unit.

[0007] The bolt assembly passes through the center of the rubber sealing strip, connecting plate a, and connecting plate b.

[0008] The structural sealant is a silicone structural sealant.

[0009] The structural sealant is located below the center of the waterproof tape.

[0010] The upper surfaces of adjacent base plates are coplanar.

[0011] The beneficial effects of this utility model include: 1. The connection between adjacent base plate units is located at the bottom outside the water collection tank, that is, the bolt assembly and bolt holes are located at the bottom outside the water collection tank, which replaces the connection method of bolts passing through the bottom of the water collection tank to fix the base plate of the water collection tank in the prior art, effectively preventing water leakage from the bolt holes.

[0012] 2. Rubber sealing strips are installed around the bolts, and structural sealant is applied to the top of the rubber sealing strips to prevent water leakage at the joints between adjacent base plates.

[0013] 3. Apply waterproof tape over the structural sealant. The waterproof tape isolates the rubber sealing strip and structural sealant from water, extending their service life and also providing a seal.

[0014] 4. Improved sealing of the water collection tank bottom plate reduces the frequency of sealing tests, increases cooling tower efficiency, reduces maintenance costs, and reduces water waste.

[0015] 5. A triple seal is achieved through rubber sealing strips, structural sealant, and waterproof tape, effectively preventing water leakage at the connection points of the base plate. Attached Figure Description

[0018] The following is in conjunction with the appendix Figure 1 Further explanation of this utility model: A multi-seal structure for a cooling tower water collection tank includes a water collection tank bottom plate assembly. The bottom plate assembly includes several adjacent bottom plate units. Each bottom plate unit includes a bottom plate body 1 and connecting structures a and b symmetrically arranged at both ends of the bottom plate body 1. The upper surfaces of adjacent bottom plate bodies 1 are coplanar to ensure the flatness of the bottom surface inside the water collection tank. The connecting structures a and b of adjacent bottom plate units are sealed together by a sealing structure. The connecting structure a includes a connecting plate a2 vertically connected to the bottom plate body 1, and a reinforcing rib a3 vertically connected to the bottom of the connecting plate a2. The connecting structure b includes a connecting plate b4 vertically connected to the bottom plate body 1, and a reinforcing rib b5 vertically connected to the bottom of the connecting plate b4. The reinforcing rib can enhance the rigidity of the connecting plate and avoid the impact on the sealing performance caused by the deformation of the connecting plate at the connection.

[0019] The sealing structure includes a rubber sealing strip 8, a bolt 6 assembly, a structural sealant 9, and a waterproof tape 10. The structural sealant 9 is a silicone structural sealant. The rubber sealing strip 8 is disposed between the connecting plate a2 and the connecting plate b4. The bolts 6 of the bolt 6 assembly pass through the center of the rubber sealing strip 8, the connecting plate a2, and the connecting plate b4 and are tightened by nuts 7, so that the two sides of the rubber sealing strip 8 are tightly fitted with the connecting plate a2 and the connecting plate b4 to achieve a seal. The top of the rubber sealing strip 8 is provided with structural sealant 9, which is adhered to the top between the connecting plate a2 and the connecting plate b4. The waterproof tape 10 is provided above the structural sealant 9, and the structural sealant 9 is located below the center of the waterproof tape 10. The two ends of the waterproof tape 10 are respectively sealed and adhered to the base plate body 1 of the adjacent base plate unit.

[0020] During assembly of the water collection tank bottom plate unit, the rubber sealing strip 8 is sandwiched between two connecting plates (i.e., connecting plate 2 and connecting plate b4) and tightened with bolts to provide pressure for the elastic deformation of the rubber sealing strip 8. Before applying the structural sealant 4, ensure that the surfaces of the parts are free of oil and dust. After applying the sealant, smooth the structural sealant 4. After the structural sealant 4 is completely dry, apply a layer of waterproof tape 5. Through the rubber sealing strip, structural sealant, and waterproof tape, a triple seal is achieved, effectively preventing water leakage at the joints of the bottom plate body.
