Description

Technical Field

[0001] The utility model relates to the technical field of water purification, in particular to a seawater filter screen. Background Art

[0002] Power plants near rivers, lakes and the coast generally draw surface water from nature for physical cooling of condensate. The surface water is physically cooled by being drawn through a pipeline, absorbs heat, and after the temperature is increased by 5 - 10 °C, it is discharged back to the extraction location and reused after natural heat dissipation.

[0003] Common surface water contains a large amount of organic matter and plankton. After being stirred by a water pump and flowing through a pipeline, suspended foam will be generated. After being discharged into nature, the foam floats on the water surface, affecting the environment and not meeting the working requirements of water purification. For this reason, a seawater filter screen is proposed. Content of the Utility Model

[0004] (1) Technical Problems to be Solved

[0005] In view of the deficiencies of the prior art, the utility model provides a seawater filter screen to solve the technical problem that suspended foam will be generated after being stirred by a water pump and flowing through a pipeline, and the foam floats on the water surface after being discharged into nature, affecting the environment.

[0006] (2) Technical Solutions

[0007] To achieve the above object, the utility model provides the following technical solution: A seawater filter screen, comprising:

[0008] A filter screen and the ground. The top of the filter screen is connected to the bottom of the ground through a bearing, and an installation frame is installed on the right side of the top of the ground;

[0009] A hinge ear is installed at the lower right of the filter screen. A reel is installed inside the installation frame through a rotating shaft. A traction rope is sleeved outside the hinge ear, and the upper part of the traction rope is wound around the outer circumference of the reel;

[0010] A driving motor is installed on the right side of the installation frame. The right end of the reel penetrates through the corresponding position of the installation frame, and a second gear is coaxially installed at the right end of the reel. The rotor of the driving motor is coaxially connected to the right side of the second gear.

[0011] Preferably, the filter screen is made of 2520 stainless steel, which improves the corrosion resistance of the filter screen. The aperture of the filter screen is set to 4 mm, and a space is reserved between the bottom end of the filter screen and the bottom of the downstream culvert.

[0012] Preferably, a lead screw is installed above the reel on the left side inside the mounting bracket through a ball bearing. A slider is screwed onto the outside of the lead screw. The bottom end of the towing rope passes through the inside of the slider. The added slider avoids the problem of the towing rope being wound or knotted during the retraction and extension process.

[0013] Preferably, a guide rod is installed above the lead screw inside the mounting bracket. The guide rod passes through the upper side inside the slider, which can limit the slider and enable the slider to move left and right when the lead screw rotates.

[0014] Preferably, the right end of the lead screw passes through the corresponding position on the right side of the mounting bracket. A first gear is coaxially installed at the right end of the lead screw. The first gear meshes with the second gear, which facilitates the rotation of the lead screw driven by the first gear when the driving motor drives the second gear to rotate.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the present utility model provides a seawater filter, which has the following beneficial effects:

[0017] For this seawater filter, after installing the filter screen at the downstream culvert opening, the foam floating on the surface of the cooling water is blocked by the filter screen. After the foam is blocked in the pool and irradiated by sunlight, the surface of the foam dehydrates and disappears. The foam in the pool finally stabilizes at a certain thickness layer and no longer increases. This design has a low cost. By adding a filter screen, the surface of the cooling water can be cleaned. And because there is a reserved space between the bottom of the filter screen and the bottom of the downstream culvert, the cooling water discharge will not be reduced due to the filter screen. At the same time, the foam cannot flow out from the bottom, which enhances the purification effect of the cooling water. At the same time, the driving motor can drive the rotation of the reel, and thus the filter screen can be driven to tilt by the towing rope, which facilitates adjusting the tilt angle of the filter screen, making it easier to adjust the filter screen according to the amount and characteristics of the foam, and also facilitating regular cleaning and maintenance.

A second gear 10 is coaxially installed at the right end of the reel 5, and the rotor of the drive motor 11 is coaxially connected to the right side of the second gear 10. Please refer to Figure 3 and Figure 4, after installing the filter net 1 at the downstream culvert opening, the foam floating on the surface of the cooling water is blocked by the filter net 1. After the foam is blocked in the pool and irradiated by sunlight, the surface of the foam dehydrates and disappears. The foam in the pool finally stabilizes at a certain thickness layer and no longer increases. This design has a low cost. By adding a filter net, the surface of the cooling water can be cleaned. And because there is a reserved space between the bottom of the filter net 1 and the bottom of the downstream culvert, the filter net 1 will not reduce the drainage volume of the cooling water. At the same time, the foam cannot flow out from the bottom, which enhances the purification effect of the cooling water. At the same time, the driving motor 11 can drive the rotation of the reel 5, so that the filter net 1 can be driven to tilt by the traction rope 4, which facilitates the adjustment of the tilt angle of the filter net 1, making it easier for the filter net 1 to be adjusted according to the amount and characteristics of the foam, and is also convenient for regular cleaning and maintenance. Please refer to Figure 2 , on the left side inside the mounting frame 2, a lead screw 6 is installed through a ball bearing at a position above the reel 5. A slider 7 is screwed onto the outside of the lead screw 6. The bottom end of the traction rope 4 passes through the inside of the slider 7. A guide rod 8 is installed inside the mounting frame 2 at a position above the lead screw 6. The guide rod 8 passes through the upper side inside the slider 7. The right end of the lead screw 6 passes through the corresponding position on the right side of the mounting frame 2. A first gear 9 is coaxially installed at the right end of the lead screw 6. The first gear 9 meshes with the second gear 10.

[0028] In this solution, after installing the filter net 1 at the downstream culvert opening, the foam floating on the surface of the cooling water is blocked by the filter net 1. After the foam is blocked in the pool and irradiated by sunlight, the surface of the foam dehydrates and disappears. The foam in the pool finally stabilizes at a certain thickness layer and no longer increases. This design has a low cost. By adding a filter net, the surface of the cooling water can be cleaned. And because there is a reserved space between the bottom of the filter net 1 and the bottom of the downstream culvert, the filter net 1 will not reduce the drainage volume of the cooling water. At the same time, the foam cannot flow out from the bottom, which enhances the purification effect of the cooling water. At the same time, the driving motor 11 can drive the rotation of the reel 5, so that the filter net 1 can be driven to tilt by the traction rope 4, which facilitates the adjustment of the tilt angle of the filter net 1, making it easier for the filter net 1 to be adjusted according to the amount and characteristics of the foam, and is also convenient for regular cleaning and maintenance.
