Description

Technical Field

[0001] This invention relates to the field of high-temperature liquid recovery technology, and more specifically, to a high-temperature liquid recovery control device. Background Technology

[0002] Hydraulic actuators offer higher output thrust than pneumatic and electric actuators, and their output torque can be precisely adjusted as required, reflected by hydraulic instruments. Hydraulic actuators provide smoother and more reliable transmission, with buffering and no impact, making them suitable for environments with high transmission requirements. They also offer high adjustment precision and fast response, enabling high-accuracy control. However, during the use of hydraulic actuators, the used liquid is typically collected in a tank and periodically pumped back into the system for reuse. However, due to the long residence time of the liquid in the tank, it easily deteriorates, and the large system size increases the likelihood of contamination, resulting in almost complete discharge and excessively high recycling costs. Therefore, we propose a high-pressure hydraulic control recycling device to improve the quality of stored liquid and eliminate the need for additional power for auxiliary recycling operations.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0035] Example

[0036] like Figure 1-12As shown, the high-pressure liquid control recovery device includes a housing 1. A door 2 is installed at the front end of the housing 1 via a hinge. A connecting valve 3 and a solenoid valve 7 are respectively installed at both ends of the upper surface of the housing 1. The input end of the connecting valve 3 and the output end of the solenoid valve 7 are connected to each other via a connecting pipe. The input end of the solenoid valve 7 is connected to the output end of the condensate pump 12 via a connecting pipe. The condensate pump 12 is installed at the rear of the housing 1. A water tank 4 is installed inside the housing 1 via a positioning and installation mechanism 5. Placement plates 101 are respectively installed at both ends of the lower surface of the housing 1. The 101 are relatively parallel to each other. The upper and lower ends of the first placement plate 101 are respectively equipped with shaft-assisted drain pipe 9 and shaft-assisted water seal cylinder 10. The shaft-assisted drain pipe 9 and shaft-assisted water seal cylinder 10 are parallel to each other vertically. A condenser 11 is installed on one side of the box body 1. The water tank 4, shaft-assisted drain pipe 9, shaft-assisted water seal cylinder 10 and condenser 11 are connected to each other through pipes. The upper end of the water tank 4 is equipped with a sliding cleaning mechanism 6. The output end of the connecting valve 3 is connected to the drain pipe 8. The lower end of the drain pipe 8 is installed through the upper end of the box body 1 and is parallel to the water tank 4 vertically.

[0037] In the specific setup, a handle 201 is installed on the front surface of the tank door 2, away from the hinge. An overflow pipe 13 is installed on the upper rear side of the inside of the water tank 4. A sealing cover 401 is snapped onto the upper end of the water tank 4. A drain pipe 15 is installed on the lower rear side of the inside of the water tank 4. The rear ends of the overflow pipe 13 and the drain pipe 15 are respectively installed through the rear side of the tank body 1. A valve 14 is installed inside the drain pipe 15. In the working state, the sealing cover 401 snaps onto the water tank 4 to maintain the sealing performance inside the water tank 4. When it is necessary to clean the inside of the water tank 4 later, the sealing cover 401 is removed, and then the inner surface of the water tank 4 is cleaned by scraper 603 and scraper 604. During use, the user opens the solenoid valve 7, allowing the condensate pump 12 to inject hydraulic water into the upper part of the piston inside the connecting valve 3, quickly forming a pressure zone, and then pushing the piston and valve rod downwards quickly. The valve core is quickly closed and the bypass is connected, so that even if the water supply to and from the high-pressure heater is cut off, the water flow will still ensure the water supply demand through the bypass. Then the user closes the solenoid valve 7 and the condensate pump 12 to stop the hydraulic water from entering. Then the hydraulic water in the upper part of the piston falls into the lower part through the small hole on the piston, and enters the water tank 4 through the drain pipe 8. After the water flows into the water tank 4, it enters the shaft heater drain pipe 9 and the shaft heater water seal cylinder 10 through the pipes respectively, and finally enters the condenser 11 through the shaft heater water seal cylinder 10.

[0038] In its specific configuration, the positioning and installation mechanism 5 includes several support plates 501. Each support plate 501 is fixedly installed at both ends of the middle of the tank body 1. The lower end of the water tank 4 is placed on the upper surface of the support plate 501. A positioning plate 502 is fixedly installed at the rear end of the upper surface of each support plate 501. The water tank 4 is positioned and installed through the cooperation between the limiting plate 506 and the positioning plate 502, making the water tank 4 more stable during operation and facilitating the user's disassembly and maintenance of the water tank 4 in the future, making it simpler and more convenient.

[0039] In the specific setup, each positioning plate 502 is fitted to the rear side of the water tank 4. Each positioning plate 502 has a groove 504 on its upper surface front end, and a connecting groove 505 extends through the lower surface of each groove 504, near the end closest to the water tank 4. The positioning plates 502 are used to limit the position of the water tank 4, ensuring that the water tank 4, along with the sealing cover 401, is vertically parallel to the drain pipe 8, making it easier for the user to install the drain pipe 8.

[0040] In the specific setup, a limiting plate 506 is movably installed inside each connecting slot 505. The upper end of each limiting plate 506 is in contact with the water tank 4. A rubber pad 503 is provided on the opposite side of each limiting plate 506 and the positioning plate 502. The limiting plate 506 is used to cooperate with the support frame 512 and the positioning plate 502 to push and fix the water tank 4, making the water tank 4 more stable during operation and preventing shaking. The rubber pad 503 can reduce wear between the positioning plate 502, the limiting plate 506 and the water tank 4, and also make the positioning plate 502, the limiting plate 506 and the water tank 4 more tightly connected.

[0041] In the specific design, each limiting plate 506 has a guide groove 507 at its lower internal end. A guide rod 508 is movably installed through each guide groove 507. Each guide rod 508 is fixedly installed inside a groove 504 and is vertically parallel to the connecting groove 505. Users can use the guide groove 507 and guide rod 508 to engage or disengage the limiting plate 506 from the connecting groove 505 for positioning the water tank 4 or for later removal of the water tank 4, making the installation process simpler, more convenient, and improving the efficiency of water tank 4 installation.

[0042] In the specific setup, each limiting plate 506 has a locking block 509 fixedly installed on the side away from the water tank 4. Each groove 504 has a movable groove 510 on its inner lower surface and at the end away from the water tank 4. A fixing rod 511 is fixedly installed at one end of each movable groove 510. A support frame 512 is movably installed through the outer side of each fixing rod 511. The upper end of each support frame 512 is engaged with the locking block 509. When the user positions the limiting plate 506 around the water tank 4 using the guide groove 507 and guide rod 508, the support frame 512 rotates around the fixing rod 511, causing the upper end of the support frame 512 to engage with the locking block 509, thus assisting in the positioning of the limiting plate 506.

[0043] In its specific configuration, the sliding cleaning mechanism 6 includes a guide slider 601 and a primary scraper 603. The guide slider 601 is fixedly installed in the middle of the upper surface of the water tank 4. The primary scraper 603 is L-shaped and is movably installed inside the water tank 4, fitting snugly against the inner surface of the water tank 4. The user uses the primary scraper 603 to scrape and remove impurities accumulated on the inner surface of the water tank 4 due to long-term operation, preventing water pollution and reducing the operating cost of the device.

[0044] In the specific setup, the upper end of the guide slider 601 is respectively engaged with the movable frame 602. The end of the movable frame 602 near the overflow pipe 13 is connected to the upper end of the first scraper 603. The upper end of the first scraper 603 is connected to the second scraper 604 via a hinge. The interior of the second scraper 604 and the end of the first scraper 603 away from the drain pipe 15 is respectively provided with a placement groove 605. The interior of the placement groove 605 is respectively equipped with a magnet 606, and the magnets 606 are magnetically attracted to each other. The user inserts the movable frame 602 into the upper end of the guide slider 601, so that the first scraper 603 is in contact with the inner surface of the water tank 4. Then, the user slides the movable frame 602 on the upper end of the guide slider 601, so that the first scraper 603 scrapes and cleans the inner surface of the water tank 4 as the movable frame 602 moves. At the same time, the user can rotate the second scraper 604 through the hinge to extend the length of the first scraper 603 and increase the cleaning speed of the water tank 4. Then, when the second scraper 604 is not in use, the magnetic attraction between the magnets 606 makes the second scraper 604 and the first scraper 603 tightly connected.

[0045] Working principle of the high-pressure liquid control recovery device:

[0046] In use, the user first installs the water tank 4 using the positioning and installation mechanism 5, then snaps the sealing cover 401 onto the upper part of the water tank 4 to form a whole. Next, the internal components of the tank body 1 are assembled. After installation, the user opens the solenoid valve 7, allowing the condensate pump 12 to inject hydraulic water into the upper part of the piston inside the connecting valve 3, quickly creating a pressure zone. This pushes the piston and valve stem downwards, rapidly closing the valve core and connecting the bypass. The user then closes the solenoid valve 7 and the condensate pump 12, stopping the hydraulic water from entering. The hydraulic water in the upper part of the piston then falls through a small hole in the piston to the lower part, and then enters the water system through the drain pipe 8. The water flows into the interior of tank 4, and then through pipes into the shaft-adding drain pipe 9 and shaft-adding water seal cylinder 10 respectively. Finally, it enters the condenser 11 through shaft-adding water seal cylinder 10. When the water level inside tank 4 is higher than the overflow pipe 13, the excess water will be discharged through the overflow pipe 13. When the user needs to clean tank 4 later, the drain pipe 15 can be opened through valve 14 to allow the water to be discharged through the drain pipe 15. Then, the pipe at the lower end of the interior of tank 4 can be blocked with a wooden plug or other items to prevent impurities generated during cleaning from entering the shaft-adding drain pipe 9 and shaft-adding water seal cylinder 10 through the pipe.

[0047] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
