Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, and in particular to a filtration device for cooling towers. Background Technology

[0002] In the smelting process, water is a crucial cooling medium, essential for temperature control of equipment such as furnaces and boilers. To conserve resources, the water needs to be cooled and recycled. After a certain period of circulation, the cooling water will contain impurities, causing corrosion to pipes and pumps. Scale will also form on the heating surfaces of the water jacket and at pipe bends, affecting flow rate. Therefore, when using cooling towers, the cooling water needs to be filtered to remove impurities, maintain water quality, and reduce maintenance frequency. In existing filter presses, the filter plates require manual cleaning after a period of use to ensure good filtration performance; however, manual cleaning is inefficient. Utility Model Content

[0003] The purpose of this utility model is to provide a filtration device for cooling towers that can quickly separate and clean the filter frame plates.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A filtration device for a cooling tower includes a filter support groove, which is fixed on a filter support frame. A support frame is provided on the top of the filter support groove. A first sliding limit rod group is provided inside the support frame. A plurality of filter frame plates are slidably locked on the first sliding limit rod group. A pressure supply device is provided on the right side of the support frame. A separation and cleaning device is provided at the top of the support frame. The separation and cleaning device includes a second sliding limit rod group, which is fixed inside the support frame. A first support cross plate and a second support cross plate are slidably provided on the second sliding limit rod group. A first electric hydraulic cylinder is vertically downward on the first support horizontal plate, and a separation plate is fixed on the piston rod of the first electric hydraulic cylinder. A second electric hydraulic cylinder is vertically downward on the first support horizontal plate, and a scraper is fixed on the piston rod of the second electric hydraulic cylinder.

[0008] As an improvement: a filter screen is provided inside the filter support groove, and a drain pipe is provided at the bottom of the filter support groove; A first discharge guide groove and a second discharge guide groove are respectively provided on the left and right sides of the filter support groove.

[0009] In summary, this utility model has the following beneficial effects: 1. When it is necessary to clean the filter frame plate, first separate the filter frame plate with the separation plate, and then push the filter frame plate to the right a certain distance with the first telescopic cylinder so that the scraper can act between the filter frame plates.

[0012] The present invention will now be described in further detail with reference to the accompanying drawings.

[0013] Please refer to Figures 1-2 A filtration device for a cooling tower includes a filter support groove 1, which is fixed on a filter support frame 2. A support frame 3 is provided on the top of the filter support groove 1. A first sliding limit rod group 4 is provided inside the support frame 3. Several filter frame plates 5 are slidably locked on the first sliding limit rod group 4. A pressure supply device is provided on the right side of the support frame 3. A separation and cleaning device is provided at the top of the support frame 3. The separation and cleaning device includes a second sliding limit rod group 6, which is fixed inside the support frame 3. A first support horizontal plate 7 and a second support horizontal plate 8 are slidably provided on the second sliding limit rod group 6. A first electric cylinder 9 is provided vertically downward on the first support horizontal plate 7. A separation plate 11 is fixed on the piston rod of the first electric cylinder 9. A second electric cylinder 10 is provided vertically downward on the first support horizontal plate 7. A scraper 12 is fixed on the piston rod of the second electric cylinder 10.

[0014] In this embodiment, when it is necessary to clean the filter frame plate 5, the filter frame plate 5 is first separated by the separation plate 11, and then the filter frame plate 5 is pushed to the right a certain distance by the first telescopic cylinder 13 so that the scraper 12 can act between the filter frame plates 5. The scraper 12 moves downward to scrape off the impurities on the filter frame plate 5. The above operation can quickly realize the separation and cleaning operation of the filter frame plate 5.

[0015] A first telescopic cylinder 13 is horizontally provided on the left side of the support frame 3, and the piston rod of the first telescopic cylinder 13 is fixedly connected to the first support cross plate 7; a second telescopic cylinder 14 is horizontally provided on the right side of the support frame 3, and the piston rod of the second telescopic cylinder 14 is fixedly connected to the second support cross plate 8.

[0016] A first guide rod assembly 15 is provided vertically upward on the separation plate 11, and the first guide rod assembly 15 is slidably limited within the first support horizontal plate 7; a second guide rod assembly 16 is provided vertically upward on the scraper frame 12, and the second guide rod assembly 16 is slidably limited within the second support horizontal plate 8.

[0017] The pressurizing device includes a pressurizing cylinder 17, which is horizontally mounted on the right side of the support frame 3. A pressurizing head 18 is fixed on the piston rod of the pressurizing cylinder 17, and a guide limiting plate 19 is provided on the piston rod of the pressurizing cylinder 17. The guide limiting plate 19 is slidably engaged with the first sliding limiting rod assembly 4. In this embodiment, the pressurizing cylinder 17 is used to press the filter frame plates 5 together, and at the same time, it plays a supporting role when cleaning the filter frame plates 5.

[0018] A filter screen 20 is provided inside the filter support trough 1, and a drain pipe 21 is provided at the bottom of the filter support trough 1; a first discharge guide trough 22 and a second discharge guide trough 23 are respectively provided on the left and right sides of the filter support trough 1. In this embodiment, the filter screen 20 can prevent the separated impurities from falling into the drain pipe 21, and also facilitates the cleaning of impurities.

[0019] Working principle: Start the first telescopic cylinder 13 to move the separating plate 11 above the gap between the filter frame plates 5. Start the first electric hydraulic cylinder 9 to move the separating plate 11 downward into the gap between the filter frame plates 5, separating the two filter frame plates 5. Then start the first telescopic cylinder 13 again to move the right filter frame plate 5 a certain distance to the right through the separating plate 11. This distance allows the scraper 12 to act precisely between the separated filter frame plates 5.

[0020] During separation, the pressure cylinder 17 drives the pressure head 18 to move a certain distance to the right, which is consistent with the width of the scraper frame 12. Then, the separation plate 11 is pulled out from between the filter frame plates 5 and moved to the left so as not to hinder the operation of the scraper frame 12.

[0021] Then, the second telescopic cylinder 14 is activated to move the scraper 12 to the left, so that it moves above the gap between the separated filter frame plates 5. The second electric hydraulic cylinder 10 is activated to move the scraper 12 downward, so that it acts on the gap between the filter frame plates 5 to perform the scraping operation. After the scraping is completed, the above actions are repeated.

[0022] The impurities generated during the scraping and cleaning process fall onto the filter screen 20, which can be cleaned periodically using external equipment or manually.
