Description

Technical Field

[0001] This application relates to the field of papermaking machine technology, and in particular to a water-blocking device for the press section of a papermaking machine. Background Technology

[0002] A paper machine is a general term for a complete set of equipment that links different parts of the pulp to form a paper web. It includes main components such as the headbox, wire section, press section, dryer section, calender, winding machine, and drive section, as well as auxiliary systems such as steam, water, vacuum, lubrication, and heat recovery.

[0003] Currently, during the pressing process, the internal water in the pulp is continuously squeezed out. Although most of the water is squeezed out and falls directly into the collection box for collection during pressing, there are still cases where water splashes out due to the compression of the pulp. This not only causes pollution in the processing area but also affects surrounding equipment. Therefore, a water-blocking device for the pressing section of a paper machine has been designed to solve the above-mentioned problems. Utility Model Content

[0004] To address this problem, this application provides a water-blocking device for the press section of a paper machine.

[0009] Preferably, the width of the cleaning brush is adapted to the water baffle, and the cleaning brush is in contact with the side wall of the water baffle.

[0010] Preferably, the slider is threadedly connected to a reciprocating lead screw, and the lower end of the reciprocating lead screw is rotatably connected to the side wall of the support frame.

[0011] Preferably, a throttle is fixedly connected to the upper end of the reciprocating screw, and the throttle is located at the upper end of the support frame.

[0012] Preferably, the slider is fixedly connected to one side of the slide plate, and the slide plate is slidably connected to the side wall of the support frame.

[0021] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0022] This application discloses a water-blocking device for the press section of a paper machine. (Refer to...) Figure 1-3 A water-blocking device for the press section of a paper machine includes a press component 1, a collection box installed at the lower end of the press component 1, and water-blocking components installed on one side and at the front and rear of the press component 1.

[0023] The water-blocking component includes a support frame 2, a slider 4 is slidably installed on one side of the support frame 2, the slider 4 is threadedly connected to a reciprocating screw 3, the lower end of the reciprocating screw 3 is rotatably connected to the side wall of the support frame 2, a water-blocking plate 5 is fixedly connected to one side of the slider 4, a collection frame 10 is fixedly connected to the lower end of the water-blocking plate 5, several discharge pipes 11 are fixedly connected to the lower end of the collection frame 10, and a water collection frame 12 is fixedly connected to the upper end of one side of the support frame 2, the water collection frame 12 is located directly below the collection frame 10.

[0024] When the pressing component 1 presses and dewaters the pulp, the water that is pressed out will fall directly into the collection box set at the lower end of the pressing component 1. Some water will splash directly due to the pressure and splash onto the baffle plate 5, which will block the splashing. After being blocked, the water will fall down along the side wall of the baffle plate 5 into the collection frame 10. The water in the collection frame 10 will drip into the water collection frame 12 through the feed pipe 11 and be filtered by the filter screen 13 to remove impurities, seasonings and additives from the water for subsequent water treatment.

[0025] By adopting the above technical solution, the upper end of the reciprocating screw 3 is fixedly connected to the handle 31, which is located at the upper end of the support frame 2, so as to drive the reciprocating screw 3 to rotate and drive the slider 4 to move. In order to make the slider 4 move smoothly, the slide plate 41 is also fixedly connected to one side of the slider 4, and the slide plate 41 is slidably connected to the side wall of the support frame 2.

[0026] The rotatable handle 31 drives the reciprocating screw 3 to rotate, which in turn drives the slider 4 to move. The slider 4 then moves the baffle 5, thereby adjusting the height of the baffle 5. This allows the baffle 5 to be adjusted according to the pressure requirements of the pressing component 1 when pressing the pulp, thus preventing water from splashing.

[0027] By adopting the above technical solution, the splashed water contains impurities and additives, and some of the impurities in the water will directly adhere to the water baffle 5. If they continue to accumulate, they will affect the water-blocking effect of the water baffle 5. The uneven surface of the water baffle 5 will cause water to splash again after contact with it, thus weakening the water-blocking effect of the water baffle 5. Therefore, the upper end of the water baffle 5 is fixedly connected to the multi-stage electric push rod 6, the output end of the multi-stage electric push rod 6 is fixedly connected to the mounting plate 7, the lower end of the mounting plate 7 is fixedly connected to the mounting block 8, and a cleaning brush 9 is fixedly connected to one side of the mounting block 8. The width of the cleaning brush 9 is adapted to the water baffle 5, and the cleaning brush 9 is in contact with the side wall of the water baffle 5.

[0028] The multi-stage electric push rod 6 drives the mounting plate 7 to descend, the mounting plate 7 drives the mounting block 8 to descend, and the mounting block 8 drives the cleaning brush 9 to descend, so that the cleaning brush 9 cleans away the impurities adhering to the baffle plate 5 and makes them fall down the feed pipe 11 onto the filter screen 13 for collection and centralized processing, ensuring that the surface of the baffle plate 5 is flat.

[0029] A filter screen 13 is fixedly installed inside the water collection frame 12 to filter out impurities in the water, facilitating subsequent water treatment.

[0030] The implementation principle of a water-blocking device for the press section of a paper machine according to an embodiment of this application is as follows: Figure 1 To illustrate, the three support frames 2 are pushed to one side and back and forth of the pressing component 1, so that the baffle plate 5 faces the pressing component 1. When the pressing component 1 is used to press and dewater the pulp, the water that is pressed out will fall directly into the collection box set at the lower end of the pressing component 1. Some water will splash directly due to the pressure and splash onto the baffle plate 5, which will block it and prevent splashing. After being blocked, the water will fall down along the side wall of the baffle plate 5 into the collection frame 10. The water in the collection frame 10 will drip into the water collection frame 12 through the feed pipe 11 and be filtered by the filter screen 13 to remove impurities, seasonings and additives from the water for subsequent water treatment.

[0031] Some impurities in the water will directly adhere to the baffle plate 5. If they continue to accumulate, they will affect the water-blocking effect of the baffle plate 5. The uneven surface of the baffle plate 5 will cause water to splash again after contact with it, thus weakening the water-blocking effect of the baffle plate 5. Therefore, when using the baffle plate, the multi-stage electric push rod 6 can be activated to drive the mounting plate 7 to descend. The mounting plate 7 drives the mounting block 8 to descend, and the mounting block 8 drives the cleaning brush 9 to descend. This allows the cleaning brush 9 to clean the impurities adhering to the baffle plate 5 and let them fall down the discharge pipe 11 onto the filter screen 13 for collection and centralized processing, ensuring that the surface of the baffle plate 5 is flat.
