This achieves the effect of cleaning the surface of the two sets of filter plates, reducing the need for frequent disassembly and cleaning of the filter plates, and improving the efficiency of the condensate recovery and utilization device.

Description

Technical Field

[0001] This utility model relates to the field of papermaking technology, specifically to a condensate recovery and utilization device for papermaking. Background Technology

[0002] In the papermaking process, wet paper webs are generally dried by sticking them to the surface of the drying cylinder. Inside the drying cylinder, hot steam is passed through, and the heat of the steam is conducted to the surface of the drying cylinder to heat and dry the wet paper web. The condensate formed after the steam releases heat is discharged through the siphon pipe inside the drying cylinder. Because the condensate contains certain impurities, it needs to be filtered through a recycling device before it can be discharged into other equipment for reuse.

[0003] Existing condensate recovery devices typically collect condensate by filtering it in a container with a filter plate. However, the filter plate often gets clogged due to the accumulation of impurities, requiring frequent disassembly, cleaning, and replacement. The replacement process is cumbersome, resulting in low condensate recovery efficiency.

[0004] According to CN219185879U, a papermaking condensate recovery device includes a tank, a fastening element, a filter element, and a bonding element. The fastening element is provided on one side of the outer end of the tank. The filter element is provided inside the tank, and the bonding element is provided at the bottom of the filter element. The bonding element includes a second filter screen, a positioning block, and a positioning groove. The positioning block is provided at the bottom of the second filter screen, and the positioning groove is provided on the side of the second filter screen.

[0005] According to the papermaking condensate recovery device described above, considering that the filter screen is prone to clogging, the tank is designed as an assembly type to facilitate cleaning of the filter screen after opening. However, this solution also suffers from the aforementioned problem of needing to frequently disassemble the filter plate for cleaning and replacement, and the replacement of the filter plate is quite cumbersome. Opening the tank requires large equipment, resulting in low condensate recovery efficiency. Therefore, we need to propose a papermaking condensate recovery and utilization device.

[0023] 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.

[0024] Please see Figure 1-5This utility model provides a papermaking condensate recycling device, including a filter box 1. The filter box 1 includes a box body 11. The inner cavity of the box body 11 is divided into a filter chamber 13 and a collection chamber 14 by a partition plate 12. Two sets of filter plates 2 are movably inserted inside the filter chamber 13 for easy disassembly. The surface of the filter plates 2 is provided with a cleaning component 3 for cleaning impurities. The cleaning component 3 includes two sets of screw rods 36 that are installed through the box body 11. Each of the two sets of screw rods 36 is threadedly connected to a set of scrapers 37 in the middle of the filter chamber 13. The bottom of the two sets of scrapers 37 is respectively attached to the top of a set of filter plates 2. The middle of the partition plate 12 is provided with two sets of discharge ports 17 for discharging impurities.

[0025] In use, the filter box 1 is divided into a filter chamber 13 and a collection chamber 14 by a partition plate 12, which facilitates isolated operation of filtering and cleaning impurities. The two sets of filter plates 2 installed inside the filter chamber 13 perform dual filtration of condensate, improving filtration efficiency. At the same time, the cleaning component 3 rotates the two sets of screws 36 to drive the two sets of scrapers 37 to move and adhere to the surfaces of the two sets of filter plates 2, thereby scraping off impurities from the surface of the filter plates 2 and discharging them into the collection chamber 14 through the discharge port 17. This achieves the effect of quickly cleaning the surface of the filter plates 2, preventing the filter plates 2 from becoming clogged and reducing the need for frequent disassembly and cleaning of the filter plates 2. The filter plates 2 are also easy to install and remove.

[0026] A motor 31 is bolted to one side of the housing 11, and two sets of support plates 32 are fixedly installed on one side of the housing 11. A rotating rod 33 is rotatably mounted through the inner side of the two sets of support plates 32. The output shaft of the motor 31 is keyed to the bottom end of the rotating rod 33. Two sets of driving wheels 34 are fixedly fitted in the middle of the rotating rod 33. Driven wheels 35 are fixedly installed at one end of each of the two sets of lead screws 36. The outer sides of the two sets of driving wheels 34 are respectively engaged with the outer sides of one set of driven wheels 35. When the motor 31 is started, it drives the two sets of rotating rods 33 to rotate stably inside the fixed plates. Simultaneously, the rotating rods 33 drive the driving wheels 34 to rotate, and the driving wheels 34 rotate synchronously... The two driven wheels 35 drive a set of driven wheels 35 to rotate, and each set of driven wheels 35 drives a set of lead screws 36 to rotate inside the filter chamber 13. The synchronous scraper 37 moves on the outer arc surface of the lead screw 36. By controlling the stroke and rotation direction of the motor 31, the two sets of scrapers 37 can be controlled to move left and right on the top of a set of filter plates 2. When it is necessary to clean the surface of the filter plate 2, the two sets of scrapers 37 are controlled to move from right to left. After cleaning, the scrapers 37 are controlled to move to the right and reset to prepare for the next cleaning. When the scrapers 37 move, the filter plate 2 is always inserted into the concave groove 15 and will not move.

[0027] The filter chamber 13 has four sets of sliding grooves 16 symmetrically arranged on its inner side. A set of sliders 38 are fixedly installed at both ends of the two sets of scrapers 37. The four sets of sliders 38 are slidably installed inside the set of sliding grooves 16. Through the connection between the filter chamber 13, the sliding grooves 16, the scrapers 37 and the sliders 38, the scrapers 37 move on the top of the filter plate 2 while driving the sliders 38 to slide inside the sliding grooves 16. The sliders 38 limit the movement of the scrapers 37 and improve the stability of the movement of the scrapers 37.

[0028] One end of the housing 11 has two sets of concave grooves 15 that extend to the inner wall of the filter chamber 13. One end of each of the two sets of filter plates 2 is movably inserted into the interior of the filter chamber 13 through a set of concave grooves 15. Through the connection between the housing 11, the filter chamber 13, the concave grooves 15, and the filter plates 2, the filter plates 2 can be quickly and easily installed inside the filter chamber 13 through the concave grooves 15, achieving the effect of quick installation and removal of the filter plates 2, and facilitating the cleaning or replacement of the filter plates 2.

[0029] A drawer 18 extending through to the bottom of one side of the housing 11 into the collection chamber 14 is provided. A drawer box 19 is movably inserted inside the drawer 18. Through the connection between the housing 11, the collection chamber 14, the drawer 18, and the drawer box 19, impurities are discharged into the collection chamber 14 through the discharge port 17 under the push of the scraper 37. Finally, the impurities fall into the drawer box 19, and the drawer box 19 can be quickly pulled out through the drawer 18 for easy cleaning of impurities.

[0030] A water inlet pipe 4 is installed through the top of the housing 11. One end of the water inlet pipe 4, located inside the filter chamber 13, is connected to a water distribution cover 5. Several sets of drainage holes 6 are opened through the bottom of the water distribution cover 5. A drain pipe 7 connecting the filter chamber 13 is provided at the bottom of the outer side of the housing 11. Condensate is discharged through the water inlet pipe 4 into the interior of the water distribution cover 5 and finally discharged through the drain holes 6. This increases the contact area between the condensate and the filter plate 2, improving the filtration efficiency. At the same time, the drain pipe 7 at the bottom of the housing 11 is used to discharge the filtered condensate to other equipment for reuse, achieving the effect of condensate recycling.

[0031] In practical use, the condensate is first evenly discharged into the filter chamber 13 through the inlet pipe 4. After double filtration by two sets of filter plates 2, it is discharged to the bottom of the filter chamber 13. Finally, the condensate is discharged to other equipment through the drain pipe 7, realizing the effect of recycling the filtered condensate. When impurities accumulate on the top of the filter plate 2, the motor 31 is started to indirectly drive the scraper 37 to move from the top of the filter plate 2 from right to left, pushing the impurities from the top of the filter plate 2 to the collection chamber 14, thereby achieving the effect of quickly cleaning the filter plate 2, so that the filter plate 2 can maintain a high-efficiency filtration effect, reduce the frequent disassembly of the filter plate 2 due to clogging, and improve the efficiency of the condensate recycling device.

[0032] 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.
