Description

Technical Field

[0001] The utility model relates to the field of cooling tower water storage structures, in particular to a water storage tank at the bottom of a cooling tower. Background Art

[0002] Cooling towers are used in conjunction with the refrigeration host of air conditioning systems. They are used in various types of factories to cool down the high-temperature circulating water or circulating liquid generated by the factory's production process. The temperature difference of the process cooling ranges from 5 degrees to 40 degrees, for example, from 42 degrees to 32 degrees. The maximum temperature can also be reduced from 90 degrees to 60 degrees, and so on. Cooling towers used for process cooling require a water reservoir directly below the cooling tower. The volume of the water reservoir needs to range from more than 10 cubic meters to several hundred cubic meters, such as the existing small cube water collection tray and cement water reservoir (reference Figure 1 As shown in the figure, the water storage volume of the conventional cooling tower small water collection pan is too small, and it is easy to overflow, which will cause a waste of water resources. If the water storage volume is too small, it will be emptied by the water pump. If the water is not replenished in time, it will affect the normal operation of the system and even cause system failure. Large water reservoirs are conventionally made of cement, which is not environmentally friendly, has low manufacturing precision and takes a long time. The production of cement water reservoirs is all manual. The production process requires cement from the cement factory, and molds must be made before pouring cement. After pouring, it takes time to wait for the cement to solidify, so cement water reservoirs are time-consuming and costly. Therefore, we designed a water reservoir that comes with the cooling tower itself. Utility Model Content

[0003] The purpose of the utility model is to provide a water storage tank at the bottom of a cooling tower in order to solve the above problems.

[0004] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0005] A water storage tank at the bottom of a cooling tower comprises a bottom plate and a top frame, wherein a plurality of first columns are arranged between the top frame and the two sides of the bottom plate in the length direction, the first columns are evenly arranged along the length direction of the bottom plate, and a water baffle is fixedly connected between two adjacent first columns; a plurality of second columns are arranged on both sides of the bottom plate in the width direction, the second columns are evenly arranged along the width direction of the bottom plate, and a water baffle is also fixedly connected between two adjacent second columns, and the height of the second columns is equal to the height of the water baffle;

[0006] The bottom plate is provided with a sewage outlet, and the water retaining plate is provided with an overflow pipe, a manual water supply pipe, an automatic water supply pipe, a balance pipe and a water outlet pipe.

[0007] Preferably, the bottom plate is formed by splicing a plurality of panels, and a reinforcement frame is provided under the bottom plate.

[0008] Preferably, the reinforcement frame includes a square frame, a plurality of transverse support columns and a plurality of longitudinal support columns, the frame is fixedly connected to the edge below the base plate, the transverse support columns and the longitudinal support columns are vertically crossed and fixedly installed below the base plate, and both ends of the transverse support columns and the longitudinal support columns are fixedly connected to the frame.

[0009] Preferably, a plurality of oblique supports are connected between the bottom plate and the water retaining plates on the four sides to form a triangular support structure, and a distance between two adjacent oblique supports is 200 mm.

[0010] Preferably, the four sides of the water retaining plate are provided with bent edges, the width of the bent edges is 50 mm, and the water retaining plate is fixedly connected to the first column or the second column by bolts.

[0011] Preferably, the first column, the second column, the transverse support column and the longitudinal support column all adopt channel steel structure.

[0012] Preferably, the openings of the water outlet pipe located on the inner side of the water reservoir are connected to an anti-vortex filter.

[0013] Preferably, the anti-vortex filter includes a square frame and an anti-vortex plate, the three side plates of the square frame are equipped with filter screens, and one side is open, and the open side is fixedly connected to the pipe mouth of the balance pipe or the outlet pipe; the lower side of the square frame is fixedly connected to the bottom plate of the water tank, and the anti-vortex plate is installed on the upper side.

[0014] The beneficial effects are: 1. The cooling tower itself has a large water storage pan, which saves the cement water storage tank, and the production time is short, error-free, and the cost is greatly reduced. The cooling tower's all-steel water storage tank is machined and manufactured with high precision and high speed.

[0015] 2. Cement water tanks need to be cleaned frequently because they are prone to algae and fungi and are difficult to clean. If the cooling tower has its own large water tank, it will not breed algae and fungi because the water tank is made of all steel.

[0016] 3. The cement water tank needs to be drained regularly. The drainage port of the cement water tank can only be opened on the side, so the drainage is inconvenient and not thorough. The cooling tower has its own steel super-large water tank, and the drainage port can be opened at the bottom of the water tank. The drainage valve is installed. As long as the valve is opened, the sewage is automatically discharged under the action of its own weight, and there is no dead corner for drainage. It is simple, convenient and practical.

[0017] 4. The cooling tower has its own water reservoir, which saves space. The original need for a cement water reservoir is no longer necessary. Instead, the entire bottom of the cooling tower can be made into a water reservoir, which can save a lot of space.

[0018] 5. The water reservoir under the cooling tower increases the height of the cooling tower foundation, which increases the difficulty of installing the cooling tower, increases the installation time, increases the cost, and reduces the safety during installation. After the cooling tower has its own water reservoir, the gap at the bottom of the cooling tower foundation can be used to install the inlet and outlet pipes, saving the floor space of the water pipes. If a cement water reservoir is to be made, the inlet and outlet pipes can only be installed next to the cooling tower, not at the bottom of the cooling tower, which increases the floor space.

[0033] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0034] See also Figure 2-Figure 11 As shown, the utility model provides a water reservoir at the bottom of a cooling tower, including a bottom plate 1 and a top frame 5, a plurality of first columns 3 are arranged between the top frame 5 and the two sides of the bottom plate 1 in the length direction, these first columns 3 are evenly arranged along the length direction of the bottom plate 1, and a water retaining plate 2 is fixedly connected between two adjacent first columns 3, the length and width of the water reservoir are consistent with the cooling tower, the bottom plate 1 and the outer facade of the cooling tower share the first column 3, and the height of the water reservoir is proportional to the required water storage capacity, which needs to be calculated. For example, if 40 cubic meters of water storage capacity is required, the length * width of the cooling tower is 5.8 meters * 8 meters, then the height of the water tank is x = 40 ÷ 5.8 ÷ 8 = 0.86 meters, then the height of the cooling tower storage water tank is about 0.9 meters.

[0035] A plurality of second columns 4 are arranged on both sides of the width direction of the base plate 1, and these second columns 4 are evenly arranged along the width direction of the base plate 1. A water retaining plate 2 is also fixedly connected between two adjacent second columns 4, and the height of the second columns 4 is equal to the height of the water retaining plate 2. A sewage outlet 7 is provided on the base plate 1, and an overflow pipe 8, a manual water replenishing pipe 9, an automatic water replenishing pipe 10, a balance pipe 11 and a water outlet pipe 12 are provided on the water retaining plate 2.

[0036] Preferably, the base plate 1 is formed by splicing a plurality of panels, and a reinforcement frame is provided under the base plate 1 .

[0037] The reinforced frame includes a square frame 13, a plurality of transverse support columns 14 and a plurality of longitudinal support columns 15. The frame 13 is fixedly connected to the edge below the base plate 1. The transverse support columns 14 and the longitudinal support columns 15 are vertically crossed and fixedly installed below the base plate 1, and both ends of the transverse support columns 14 and the longitudinal support columns 15 are fixedly connected to the frame 13. The first column 3, the second column 4, the transverse support columns 14 and the longitudinal support columns 15 are all made of channel steel structure. Because the water output of the water tank must be more than 10 cubic meters, which is converted into a weight of at least 10 tons, the frame force structure of the water tank must be calculated according to the actual force, and the force of all water tank frame components is much greater than the conventional ones. The frame of the super-large water tank in this application adopts No. 10 channel steel (see Fig. 9 ) structure or 150*50*4mm steel section, and welded connecting pieces every 500mm to increase the overall structural strength. In this way, the above profiles are used to greatly improve the stress level and structural strength of the overall frame of the water tank, and it will not deform or leak due to the large amount of water storage. The bottom plate 1 of the water tank is made of No. 10 channel steel structure or 150*50*4mm steel section to form a 500*500 square grid. This design has a strong stress structure, uniform stress, and strong compressive resistance.

[0038] Furthermore, the four sides of the water retaining plate 2 are provided with bending edges, i.e., flanges. The width of the bending edges is 50 mm, and the water retaining plate 2 is fixedly connected to the first column 3 or the second column 4 by bolts. Holes are reserved every 200 mm on the flanges, and are connected to the columns by 304 stainless steel bolts. A butyl waterproof black rubber strip is sealed between the plates, and the sealant is always in a semi-cured state, permanently maintaining its inherent viscosity, not peeling off from the metal, not soluble in water, not affected by the external water temperature, and has excellent sealing performance to prevent water leakage. At the same time, on top of the first layer of sealant, a Changlu brand neutral glass glue is used for sealing, which prevents water leakage for a long time.

[0039] Preferably, a plurality of inclined supports 6 are connected between the bottom plate 1 and the water retaining plates 2 on the four sides to form a triangular support structure, and the spacing between two adjacent inclined supports 6 is 200 mm. This design prevents the joints from deforming under pressure, causing cracks and water leakage. After the triangular connection is adopted, the entire water tank is completely a whole, strong and durable. The water storage capacity has no effect on the water tank.

[0040] like Fig.11As shown, the opening of the outlet pipe 12 located on the inner side of the water reservoir is connected to an anti-vortex filter 16. The anti-vortex filter 16 includes a square frame 16b and an anti-vortex plate 16a. The three side plates of the square frame 16b are all installed with a filter screen 16c, and one side is open, and the open side is fixedly connected to the pipe mouth of the balance pipe 11 or the outlet pipe 12; the lower side of the square frame 16b is fixedly connected to the bottom plate 1 of the water reservoir, and the anti-vortex plate 16a is installed on the upper side. One of the functions of the anti-vortex plate 16a is to block the trajectory of the water's own weight to a certain extent. The anti-vortex plate 16a will not be flooded, and the anti-vortex plate 16a can also prevent fallen leaves from falling into the filter.

[0041] If the customer needs to increase the water storage capacity during the use of the cooling tower, then a water baffle 2 of a certain height can be added above the water baffle 2 on the side of the cooling tower. This can increase the overall water storage capacity of the cooling tower without increasing any cost or changing the tower shape and usage function of the cooling tower.

[0042] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
