Description

Technical Field

[0001] The utility model belongs to the technical field of cooling towers and relates to a high-efficiency sewage discharge device for cooling towers. Background Art

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from the system and discharge it into the atmosphere to lower the water temperature. Its cooling principle is to use the contact between water and air to exchange heat and generate steam. The steam evaporates and takes away the heat to achieve evaporative heat dissipation, convection heat transfer, and radiation heat transfer. It dissipates the waste heat generated in industry or refrigeration and air conditioning to lower the water temperature through evaporative heat dissipation to ensure the normal operation of the system. The device is generally barrel-shaped, hence the name cooling tower.

[0003] However, most of the cooling water in the cooling tower contains calcium, magnesium ions and acid carbonates. When the cooling water flows through the inner surface of the cooling tower, carbonates are produced. In addition, the oxygen dissolved in the cooling water will cause corrosion of the tower body and form scale. Due to the generation of scale, the heat exchange effect of the cooling tower is reduced.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] The following is combined with Figure 1-3 The specific implementation methods of the present utility model are further described in detail.

[0018] In this embodiment, by Figure 1-3 As shown, the utility model includes a motor 2 fixed on a tower body 1, a rotating cylinder 3 located in the tower body 1 is fixed to the output end of the motor 2, a filter plate 4 is fixed in the tower body 1, an auxiliary cylinder 5 coaxial with the rotating cylinder 3 is rotatably connected to the filter plate 4, a scraping assembly is installed on the rotating cylinder 3, a flushing assembly is installed in the tower body 1, the scraping assembly is used to drive the flushing assembly to flush the inner wall of the tower body 1, a water inlet pipe 6 is connected to the tower body 1, a water outlet pipe 7 is connected to the bottom of the tower body 1, and a cleaning door 20 is opened on the tower body 1;

[0019] The motor 2 is connected to an external industrial computer through a wire. The operation of the motor 2 drives the rotating drum 3 to rotate, and the rotating drum 3 drives the scraping component to operate to scrape and clean the inner wall of the tower body 1. At the same time, the scraping component can drive the cleaning component to clean the inner wall of the tower body 1, thereby improving the scraping efficiency and quality. After the scraping is completed, the cleaning door 20 is opened to clean out the sediment, and the outlet pipe 7 is controlled by a valve.

[0020] In this embodiment, by Figure 2-3 As shown, the scraping assembly includes a plurality of limiting rods 8 inserted into the rotating drum 3. The limiting rods 8 are square rods. A first scraper 9 and a second scraper 10 are fixed to the plurality of limiting rods 8 respectively. A track ball 11 is fixed to the first scraper 9 and the second scraper 10. A first track 12 and a second track 13 are opened on the inner wall of the tower body 1. The first scraper 9 and the second scraper 10 are slidably connected to the first track 12 and the second track 13 respectively through the track ball 11.

[0021] The first scraper 9 is slidably connected to the first track 12 through the track ball 11, and the second scraper 10 is slidably connected to the second track 13 through the track ball 11. The first track 12 and the second track 13 both undulate in a wavy pattern, and the lowest point of the first track 12 and the highest point of the second track 13 are on the same vertical line, and the highest point of the first track 12 and the lowest point of the second track 13 are on the same vertical line, so that the scraping ranges of the first scraper 9 and the second scraper 10 are different, and the inner wall of the tower body 1 is scraped;

[0022] The rotation of the rotating drum 3 drives the limiting rod 8 to rotate, and the limiting rod 8 drives the first scraper 9 and the second scraper 10 to rotate. During the rotation of the first scraper 9 and the second scraper 10, the first scraper 9 and the second scraper 10 will move up and down on the first track 12 and the second track 13 through the track ball 11, thereby improving the scraping efficiency of the inner wall of the tower body 1 and better scraping the inner wall of the tower body 1;

[0023] The number of the limiting rods 8 can be set according to requirements.

[0024] In this embodiment, by Figure 2-3 As shown, a plurality of first scrapers 9 and second scrapers 10 are distributed around the center of the motor 2 at equal intervals.

[0025] In this embodiment, by Figure 2-3 As shown, the flushing assembly includes a sleeve 14 fixed on the bottom wall of the tower body 1, a pressure plate 15 is provided above the sleeve 14, and the pressure plate 15 is fixed to the limiting rod 8. The sleeve 14 passes through the tower body 1 and is connected to a circulation pipe 16 located outside the tower body 1. The circulation pipe 16 is connected to an external pipe 17 through a ball valve 21. The water outlet end of the circulation pipe 16 is connected to an annular pipe 18 located inside the tower body 1. The annular pipe 18 is connected to a plurality of nozzles 19, and each nozzle 19 is distributed equidistantly around the center of the motor 2.

[0026] The ball valve can be a three-way ball valve with model Q45F46;

[0027] When the limiting rod 8 rotates with the rotating cylinder 3, the first scraper 9 and the second scraper 10 move up and down in a circular motion through the track block, so that the limiting rod 8 also moves up and down when rotating. The limiting rod 8 moves up and down while rotating, driving the pressing plate 15 to move up and down, thereby squeezing the water in the sleeve 14, so that the water in the sleeve 14 enters the annular pipe 18 from the circulation pipe 16, and is then sprayed out from the nozzle 19 to wash the inner wall of the tower body 1;

[0028] The cross sections of the pressing plate 15 and the sleeve 14 are both circular, and the diameter of the pressing plate 15 is equal to the inner wall diameter of the sleeve 14. The pressing plate 15 is a rubber sleeve with elasticity. When the pressing plate 15 moves downward to squeeze the water in the sleeve 14 and spray it out, the pressing plate 15 rises and deforms, so that the water in the tower body 1 continues to flow into the sleeve 14, repeatedly squeezing and flushing the inner wall of the sleeve 14. The scraping work of the inner wall of the tower body 1 can be well completed by scraping and flushing in one. When the scraping is completed, the ball valve 21 can be switched to allow the water in the sleeve 14 to flow out from the external pipe 17;

[0029] The external pipe 17 and the outlet pipe 7 are both controlled to open and close by an electric valve of model Q911F-16P;

[0030] The electric valve and the motor 2 are both connected to an external industrial computer through wires.

[0031] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
