Abstract
Description
Technical Field
[0001] This utility model relates to the field of cooling tower technology, and in particular to a foreign object collection device for an open circulating water system. Background Technology
[0002] Cooling towers are structures used to cool water, commonly found in power plants, chemical plants, cement plants, and other factories that require strict water temperature control. Their height is determined by calculations based on heat exchange capacity. Cooling towers are structures that conserve and recycle water. The working principle of a cooling tower is as follows: It utilizes the convection between the incoming air and the water sprayed from above to remove heat. Some of the water evaporates during this convection, carrying away the latent heat of vaporization. This process lowers the water temperature.
[0003] Cooling towers are installed outdoors, and open-type cooling towers are more prone to letting foreign objects, such as willow catkins, into their water tanks. In addition, due to factors such as sunlight, algae can easily grow in the water tanks. Although there is a filter structure at the outlet of the water tank, the filter area is relatively small. When water is supplied, the large water flow can cause foreign objects to crowd into the outlet and clog the filter structure. Utility Model Content
[0004] To address the aforementioned problems, this utility model discloses a foreign object collection device for an open-type circulating water system. The device includes a support frame, which is inclined and has a rotating frame rotatably mounted inside. Inside the rotating frame is a frame with a filter screen fixedly connected to its inner side. A collection trough is located on one side of the filter screen at the lower position of the support frame. A mesh plate is fitted over the upper end of the rotating frame, and the inner side of the mesh plate has several through holes. In use, the device is submerged underwater. The mesh plate protects the filter screen below, while the filter screen traps foreign objects. Due to the inclined design of the support frame and the impact of the water flow, foreign objects are drawn into the collection trough as much as possible.
[0005] Preferably, a number of support legs are fixedly connected to the four lower corners of the support frame. The support legs are used to support the rotating frame.
[0006] Preferably, the rotating frame is internally fixedly connected with several limiting protrusions, and the frame and collecting groove are provided with limiting holes, which cooperate with the limiting protrusions. The limiting protrusions are used to fix the frame and collecting groove, and the frame and collecting groove completely cover the bottom of the rotating frame.
[0007] Preferably, a lever is fixedly connected to the inner wall of the collection tank. The lever allows the collection tank to be easily lifted upwards for easy removal of foreign objects.
[0008] Preferably, the side wall of the rotating frame is provided with a slot, and the edge of the mesh plate is provided with a limiting protrusion, the inner side of which is a through hole. The limiting protrusion and the slot cooperate with each other. The mesh plate is fixed by the limiting protrusion and the slot.
[0009] Preferably, a rope-attaching hole is provided at the center of one side edge of the rotating frame, and the rope-attaching hole is positioned opposite to the rotating side of the frame. A rope is connected to the rope-attaching hole, and the rotating frame is rotated by pulling the rope.
[0010] Preferably, the tilt angle of the support frame is 3 to 7°.
[0011] Preferably, the filter screen is 200 mesh. This ensures that sufficiently small foreign objects can be intercepted.
[0012] The beneficial effects of this utility model are as follows: 1. This device is submerged in the water body, achieving layering of the upper and lower parts of the water tank, with a sufficiently large filtration area. Furthermore, being submerged in the water, it is less prone to clogging due to the impact of falling water, and it also ensures normal cooling of the water.
[0013] 2. The support frame is tilted, and the rotating frame, filter screen, and collection tank on it are also tilted. If foreign objects are trapped, they will enter the collection tank under the impact of falling water, making them easy to clean.
[0014] 3. The rotating frame is installed on the support frame by rotation. By pulling the rope tied to the rope hole, the rotating frame rotates and stands upright. At this time, the screen, filter screen and collection tank can be removed without tools, which has the advantages of cleaning, replacement and maintenance. Attached Figure Description

[0017] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to the directions in the accompanying drawings, and the terms "inner" and "outer" refer to the directions toward or away from the geometric center of a specific component, respectively.
[0018] like Figures 1 to 5 As shown, an open-type circulating water system foreign object collection device includes a support frame 1, which is a rectangular frame composed of several angle steels, and several crossbars are fixedly connected to the bottom. The support frame 1 is inclined, and a rotating frame 2 is rotatably installed inside it. Similarly, the rotating frame 2 is a rectangular frame composed of several angle steels, and several crossbars are fixedly connected to the bottom. One side of the rotating frame 2 is rotatably connected to the lower position of the support frame 1. A frame 7 is set inside the rotating frame 2. The frame 7 has a rectangular structure, and a filter screen 8 is fixedly connected to the inner side of the frame 7 for intercepting foreign objects. A collection trough 6 is set on one side of the filter screen 8, and the collection trough 6 is located at the lower position of the support frame 1. The collection trough 6 is used to temporarily store foreign objects, which enter the collection trough 6 as much as possible along the inclined filter screen 8 and under the impact of the water flow. A mesh plate 3 is covered at the upper end of the rotating frame 2, and several through holes are set on the inner side of the mesh plate 3. The mesh plate 3 is used to protect the filter screen 8 below and prevent excessively large foreign objects from damaging the filter screen 9.
[0019] Several support legs 5 are fixedly connected to the four corners of the lower end of the support frame 1. The support legs 5 are used to support and fix the support frame 1.
[0020] The rotating frame 2 is internally fixedly connected with several limiting protrusions 9. The limiting protrusions 9 are cylindrical. Limiting holes are provided on the frame 7 and the collection groove 6. The limiting holes and the limiting protrusions 9 cooperate to limit the frame 7 and the collection groove 6. At the same time, it is easier to remove them. Just lift the frame 7 and the collection groove 6 upwards.
[0021] A lever 11 is fixedly connected to the inner wall of the collection tank 6. The lever 11 is designed to make it easy to lift the collection tank 6.
[0022] The side wall of the rotating frame 2 is provided with a slot 10, and the edge of the mesh plate 3 is provided with a limiting protrusion 12. The inner side of the limiting protrusion 12 is a through hole. The through hole allows the limiting protrusion 12 to deform in the direction of the through hole, so that the limiting protrusion 12 disengages from the slot 10. The limiting protrusion 12 and the slot 10 cooperate to fix the mesh plate 3 on the rotating frame 2.
[0023] A rope hole 4 is provided in the middle of one side edge of the rotating frame 2, and the rope hole 4 is opposite to the rotating side of the rotating frame 2. The rope hole 4 is provided for binding ropes. When needed, the rope can be pulled to rotate the rotating frame 2 upright.
[0024] The support frame 1 has an inclination angle of 3 to 7 degrees, which is suitable for foreign objects to enter the collection tank 6 under the impact of water flow.
[0025] The filter screen has a mesh size of 200, which meets the water circulation requirements of the cooling tower.
[0026] Working principle: When in use, place the device inside the water tank and completely immerse it in the water. During the operation of the cooling tower, the falling cooling water impacts the water surface, and the resulting waves impact the foreign objects trapped by the filter screen 8. Then the foreign objects enter the collection tank 6. If it is necessary to replace the filter screen 8 or clean the foreign objects in the collection tank 6, the pre-tied rope can be pulled. At this time, the rotating frame 2 rotates and emerges from the water.
[0027] The technical means disclosed in this utility model are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features.
