Description

Technical Field

[0001] This utility model relates to the field of cooling towers, and more specifically, to a cooling tower for waste heat treatment. Background Technology

[0002] In modern industrial production, various processes inevitably generate a large amount of waste heat. Taking steel smelting as an example, in the high-temperature steelmaking and rolling stages, a considerable amount of waste heat is generated for every ton of steel produced. If this waste heat is not properly treated, it will cause a series of serious problems. On the one hand, excessively high temperatures will damage production equipment, greatly shorten its service life, increase equipment maintenance costs and downtime, and thus affect production efficiency. On the other hand, allowing waste heat to be released unchecked will lead to an increase in the surrounding ambient temperature, disrupt the thermal balance of the ecosystem, and cause environmental problems such as the heat island effect.

[0003] In existing technologies, such as the high-efficiency cooling tower disclosed in patent CN216558391U, the device accelerates the cooling of wastewater and shortens the cooling time by adding a heat exchange radiator. However, this device has significant drawbacks in actual operation. External dust, particulate matter, and other impurities easily enter the cooling tower in large quantities through the ventilation openings. These impurities mix with the circulating water in the cooling tower and eventually flow into the collection tank. More problematic is that the impurities in the collection tank are tightly attached to the tank walls and bottom, making them difficult to remove using conventional methods. Currently, manual cleaning or high-pressure water jet washing is the only option. This not only consumes a lot of manpower and resources but also greatly reduces the efficiency of sewage discharge, increases equipment maintenance costs and operating burden, and hinders the efficient and stable operation of the entire waste heat cooling process.

[0004] Therefore, a new cooling tower for waste heat treatment needs to be designed to address the aforementioned issues. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a cooling tower for waste heat treatment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0012] In a preferred embodiment, the scraping device includes a drive shaft, which is fixedly installed at the bottom end of the motor output shaft. Two fixing rods are symmetrically fixedly installed on the outer wall of the drive shaft.

Two first scrapers are symmetrically fixedly installed on the outer wall of the bottom end of the drive shaft, and the two first scrapers contact the inner bottom wall of the cooling tower.

[0013] In a preferred embodiment, the upper surface of the filter plate is inclined, and the cleaning plate is fitted with the inclined surface.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figure 1-3 A cooling tower for waste heat treatment includes a cooling tower 1. A sliding groove 3 and an outlet groove 2 are formed on the outer wall of the cooling tower 1. An installation groove 7 is formed on the inner top wall of the outlet groove 2, and a blocking device is provided in the installation groove 7. A filter plate 10 is fixedly installed on the inner wall of the cooling tower 1. A collection groove 11 is formed on the upper surface of the filter plate 10. A through groove 12 is formed on the outer wall of the collection groove 11, and the position of the through groove 12 corresponds to the position of the outlet groove 2. Multiple support rods 6 are fixedly installed on the inner wall of the cooling tower 1. The ends of the multiple support rods 6 away from the inner wall of the cooling tower 1 are jointly fixedly connected to a protective box 5. A motor 13 is fixedly installed inside the protective box 5. A cleaning device is provided on the output shaft of the motor 13, and the output end of the cleaning device contacts the upper surface of the filter plate 10. The output shaft of the motor 13 passes through the upper surface of the filter plate 10 and extends to install a scraping device, and the output end of the scraping device contacts the inner wall of the cooling tower 1.

[0022] By incorporating a motor 13, a cleaning device, a filter plate 10, a collection tank 11, and a scraping device, the filter plate 10 can filter dust and impurities entering the cooling tower 1, thereby ensuring the cleanliness of the circulating water at the bottom of the cooling tower 1. The motor 13 can drive the cleaning device and the scraping device to work synchronously, thereby scraping the impurities on the filter plate 10 into the collection tank 11 of the filter plate 10, maintaining the filtration performance of the filter plate 10. The scraping device can also scrape away impurities from the inner wall of the cooling tower 1, preventing impurities from adhering to the inner bottom wall and inner wall of the cooling tower 1, preventing impurities from accumulating for a long time, ensuring the cleanliness of the inside of the cooling tower 1, maintaining the efficient operation of the cooling tower 1, and extending the service life of the equipment.

[0023] The blocking device includes two springs 8, which are symmetrically fixedly installed on the inner top wall of the mounting groove 7. The ends of the two springs 8 away from the inner top wall of the mounting groove 7 are fixedly installed with a stop block 9, which is slidably connected in the mounting groove 7. The bottom end of the stop block 9 is in contact with the inner bottom wall of the outlet groove 2. A connecting block 4 is fixedly installed on the outer wall of the stop block 9, and the connecting block 4 is slidably locked in the slide groove 3. The elastic properties of the two springs 8 can keep the stop block 9 in contact with the bottom wall of the outlet groove 2.

[0024] The bottom wall of the outlet channel 2 is provided with an inclined channel, which allows impurities in the collection channel 11 to be better cleaned to the outside through the inclined channel.

[0025] The cleaning device includes a fixing sleeve 14, which is fixedly installed on the output shaft of the motor 13. Multiple cleaning plates 15 are fixedly installed around the outer wall of the fixing sleeve 14, and the bottom end of each cleaning plate 15 is in contact with the upper end face of the filter plate 10. An installation block 16 is fixedly installed on the end of each cleaning plate 15 away from the fixing sleeve 14, and the installation block 16 is located in the collection tank 11.

[0026] The scraping device includes a drive shaft, which is fixedly installed at the bottom end of the output shaft of the motor 13. Two fixed rods 18 are symmetrically fixedly installed on the outer wall of the drive shaft. A second scraper 19 is fixedly installed at the end of each fixed rod 18 away from the drive shaft, and the second scraper 19 contacts the inner wall of the cooling tower 1. Two first scrapers 17 are symmetrically fixedly installed on the outer wall of the bottom end of the drive shaft, and the two first scrapers 17 contact the inner bottom wall of the cooling tower 1.

[0027] The upper surface of the filter plate 10 is inclined, and the cleaning plate 15 cooperates with the inclined surface. The inclined surface allows the impurities scraped off by the cleaning plate 15 to enter the collection tank 11 more quickly through the inclined surface.

[0028] When this utility model is in use, the motor 13 is started, and its output shaft drives the fixed sleeve 14 and the cleaning plate 15 to rotate, which efficiently cleans the impurities attached to the surface of the filter plate 10. The filter plate 10 is designed with an inclined surface, and the impurities that are cleaned off slide down and are directly scraped into the collection tank 11. While the cleaning plate 15 is operating, the mounting block 16 in the collection tank 11 rotates synchronously with it, separating the impurities that fall into the collection tank 11.

[0029] Next, the sliding connecting block 4 will drive the stop block 9 to move within the mounting slot 7. During the movement of the stop block 9, the spring 8 is compressed until it no longer blocks the outlet slot 2. At this time, the impurities in the collection slot 11 can be smoothly discharged to the outside through the through slot 12 and the outlet slot 2.

[0030] When the output shaft of motor 13 rotates, it also drives the transmission shaft to rotate. The rotation of the transmission shaft further drives the fixed rod 18 to rotate synchronously. When the fixed rod 18 rotates, the second scraper 19 begins to scrape the inner wall of the cooling tower 1, cleaning the impurities attached to the inner wall. At the same time, the first scraper 17 rotates with the transmission shaft to clean the impurities on the inner bottom wall of the cooling tower 1, ensuring that the interior of the cooling tower 1 is clean in all directions.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
