Description

Technical Field

[0001] This utility model relates to the technical field of papermaking equipment, and in particular to a papermaking pressing and dewatering mechanism. Background Technology

[0002] With the development of social productivity, people's requirements for paper quality are constantly increasing. In the papermaking process, pressing is one of the most important links. The forming of paper requires dewatering by a press. Chinese utility model patent document with announcement number CN212925601U discloses a papermaking machine pressing and dewatering system, including a base, a frame, a water collection tank, a pressing and dewatering device, a water suction roller assembly, and a heating and drying device. The pressing and dewatering device, the water suction roller assembly, and the heating and drying device are arranged sequentially from left to right on the frame. The pressing and dewatering device on the left side of the frame removes most of the water from the wet paper. The water suction roller assembly in the middle of the frame can absorb the water that is not easy to drip off during pressing. The number of water suction rollers can be set by the user. The heating and drying device on the right side of the frame further removes the moisture from the wet paper. The aforementioned paper machine pressing and dewatering system cannot effectively collect and filter the pulp wastewater produced during use. Therefore, this utility model proposes a paper pressing and dewatering mechanism that differs from the existing technology to solve the above-mentioned technical problems. Utility Model Content

[0003] In order to improve the problem mentioned above that the pulp wastewater from the press cannot be effectively collected and filtered, this utility model provides a paper press dewatering mechanism.

[0004] This utility model provides a papermaking press dewatering mechanism, which adopts the following technical solution: A paper pressing and dewatering mechanism includes a horizontal plate. A dewatering frame, a wastewater frame, and a mounting frame are respectively installed on the upper surface of the horizontal plate. The mounting frame is located on the outer side of the dewatering frame and the wastewater frame. Multiple sets of dewatering holes are evenly opened on both sides of the upper surface of the dewatering frame. A water filtering unit is installed in the inner cavity of the wastewater frame. A counterweight unit is installed on the upper surface of the mounting frame. Multiple sets of dewatering rollers are evenly installed at the bottom end of the counterweight unit. The height of multiple sets of dewatering rollers is adjusted by a counterweight unit. The dewatering rollers can press the wastewater in the pulp. The wastewater can be drained through multiple sets of dewatering holes. The wastewater pressed from the pulp is filtered through a water filtration unit.

[0005] By adopting the above technical solution, the forming wire carrying wet paper is placed on the upper surface of the dewatering frame. The counterweight unit is activated to drive the dewatering rollers to move down synchronously until multiple sets of dewatering rollers can press against the forming wire carrying wet paper. With the help of the gravity of the counterweight unit, the water in the wet paper can be squeezed out by multiple sets of dewatering rollers. Under the action of multiple sets of dewatering holes, the squeezed water can drip into the inner cavity of the wastewater frame. Under the action of the filtration unit, the pulp wastewater can be automatically filtered.

[0006] Optionally, the counterweight unit includes an electrically controlled winch and a water storage frame.

[0012] By adopting the above technical solution, the water squeezed out can drip into the inner cavity of the wastewater frame under the action of multiple sets of dewatering holes. Under the action of the mesh structure of the dewatering nylon cloth, the pulp wastewater can be automatically filtered. The drive motor is started to drive the rotating vertical shaft and the agitator to rotate, thereby agitating the pulp wastewater and enabling the pulp wastewater to be fully filtered.

[0013] Optionally, multiple sets of drain pipes are installed at the bottom of one side of the outer wall of the wastewater frame.

[0014] By adopting the above technical solution, opening the control valve on the drain pipe allows the wastewater inside the wastewater frame to be discharged.

[0015] In summary, this utility model has at least one of the following beneficial effects: Open the control valve on the water inlet corrugated hose and allow the clean water in the water storage frame to gradually flow into the dehydration frame through the water inlet corrugated hose. Start the submersible pump to extract the clean water in the dehydration frame and return it to the water storage frame through the return corrugated hose. This allows for easy adjustment of the amount of clean water in the dehydration frame, which in turn allows for adjustment of the pressure. Multiple sets of dewatering rollers can press against the forming wire carrying wet paper to squeeze out the water in the pulp. Under the action of multiple sets of dewatering holes, the squeezed water can drip into the inner cavity of the wastewater frame. Under the action of the mesh structure of the dewatering nylon cloth, the pulp wastewater can be automatically filtered, making it convenient to collect and filter the wastewater in the pulp.

Figure 1 and Figure 2 As shown, it can solve the problem of ineffective collection and filtration of pulp wastewater from pressing. It includes a horizontal plate 7, on the upper surface of which a dewatering frame 6, a wastewater frame 26 and a mounting frame 4 are respectively installed. The wastewater frame 26 is located in the inner cavity of the dewatering frame 6, and the mounting frame 4 is located on the outer side of the dewatering frame 6 and the wastewater frame 26. The lateral longitudinal section of the mounting frame 4 is set as an inverted U-shape. A counterweight unit is installed on the upper surface of the mounting frame 4. The counterweight unit includes an electrically controlled winch 19 and a water storage frame 21. The top of the water storage frame 21 is provided with a removable soft plug 18.

[0020] Combination Figure 1 and Figure 2 In this embodiment of the present invention, the electric winch 19 and the water storage frame 21 are both installed on the upper surface of the mounting frame 4. The electric winch 19 is located in the middle of the mounting frame 4. A steel wire rope 20 is installed at the output end of the electric winch 19, which penetrates the top wall of the mounting frame 4. A dewatering frame 15 is installed at the bottom end of the steel wire rope 20. A water-filling corrugated hose 1 extending to the upper end of the inner cavity of the dewatering frame 15 is installed at the bottom end of the water storage frame 21. A control valve is installed on the outside of the water-filling corrugated hose 1. Multiple sets of dewatering rollers 5 are evenly installed at the bottom end of the dewatering frame 15.

[0021] Start the electric winch 19 and stretch the wire rope 20, causing the dewatering frame 15 to move the dewatering roller 5 down to the appropriate position. Open the control valve on the water-filling corrugated hose 1 and inject clean water into the inner cavity of the water storage frame 21 into the inner cavity of the dewatering frame 15. Use multiple sets of dewatering rollers 5 to squeeze out the water from the wet paper.

[0022] Combination Figure 1 and Figure 2 In this embodiment of the invention, submersible pumps 3 are installed at both ends of the bottom of the inner cavity of the dehydration frame 15. The submersible pumps 3 are electrically connected to an external power source via waterproof cables. The output ends of the two sets of submersible pumps 3 are equipped with return water corrugated hoses 2 that extend to the upper end of the inner cavity of the water storage frame 21. When the submersible pumps 3 are started, clean water is drawn from the inner cavity of the dehydration frame 15 and fully returned to the inner cavity of the water storage frame 21 through the return water corrugated hoses 2, which facilitates the adjustment of the clean water volume in the inner cavity of the dehydration frame 15.

[0023] Combination Figure 1 , Figure 3 and Figure 4In this embodiment of the present invention, multiple sets of dehydration holes 14 are evenly opened on both sides of the upper surface of the dehydration rack 6. The multiple sets of dehydration holes 14 are all located directly above the wastewater frame 26. A water filtration unit is installed in the inner cavity of the wastewater frame 26. The water filtration unit includes a support plate 23. Multiple sets of support plates 23 are provided. The longitudinal section of the support plate 23 is set as an inverted T shape. The multiple sets of support plates 23 are respectively installed at the upper end of the periphery of the inner cavity of the wastewater frame 26. A connecting block 22 is provided on the upper surface of the multiple sets of support plates 23. The bottom end of the multiple sets of connecting blocks 22 is provided with an insertion hole 24 that engages with the support plate 23. A dehydration nylon cloth 10 is installed on the outer wall of the multiple sets of connecting blocks 22. A pull ring 25 is installed on the top wall of the multiple sets of connecting blocks 22.

[0024] The multiple sets of dewatering holes 14 allow the pressed water to drip into the inner cavity of the wastewater frame 26, and the mesh structure of the dewatering nylon cloth 10 automatically filters the pulp wastewater.

[0025] Combination Figure 1 and Figure 2 In this embodiment of the invention, multiple sets of vertical tubes 17 are installed at both ends of the upper surface of the mounting frame 4. T-shaped vertical rods 16, which penetrate the top wall of the mounting frame 4, are movably inserted through the inner cavity of each set of vertical tubes 17. The longitudinal section of the T-shaped vertical rods 16 is T-shaped. Both the T-shaped vertical rods 16 and the vertical tubes 17 are positioned on the outer side of the water storage frame 21. The bottom ends of the T-shaped vertical rods 16 are fixed to the upper surface of the dehydration frame 15. When the dehydration frame 15 moves up and down, it can drive the multiple T-shaped vertical rods 16 to move synchronously within the inner cavity of the vertical tubes 17, thereby restricting the movement path of the dehydration frame 15.

[0026] Combination Figure 1 In this embodiment of the invention, a motor frame 8 is installed at the middle position of the top of the inner cavity of the dewatering rack 6. A drive motor 13 is installed at the bottom of the inner cavity of the motor frame 8. A rotating vertical shaft 12 penetrating the bottom wall of the motor frame 8 is installed at the output end of the drive motor 13. An agitator 9 is installed at the bottom of the outer wall of the rotating vertical shaft 12. Starting the drive motor 13 drives the rotating vertical shaft 12 and the agitator 9 to rotate, thereby agitating the pulp wastewater and enabling the pulp wastewater to be fully filtered.

[0027] Combination Figure 1 and Figure 3 In an embodiment of this utility model, multiple sets of drain pipes 11 are installed at the bottom of one side of the outer wall of the wastewater frame 26, and control valves are installed on the outside of the drain pipes 11. Opening the control valves on the drain pipes 11 allows the wastewater inside the wastewater frame 26 to be discharged.

[0028] Working principle: When using this paper pressing and dewatering mechanism, first, the horizontal plate 7 is placed stably in an appropriate position. Then, the forming wire carrying wet paper is placed on the upper surface of the dewatering frame 6. Under the action of the existing papermaking equipment traction mechanism, the forming wire carrying wet paper can be pulled to move. Start the electric control hoist 19 and make the wire rope 20 stretch, so that the dewatering frame 15 drives the dewatering roller 5 to move down synchronously until multiple sets of dewatering rollers 5 can press against the forming wire carrying wet paper. Pull out the soft plug 18 and inject an appropriate amount of clean water into the inner cavity of the water storage frame 21. Open the control valve on the water inlet corrugated hose 1 and let the clean water in the inner cavity of the water storage frame 21 be gradually injected into the inner cavity of the dewatering frame 15 through the water inlet corrugated hose 1. Thus, with the help of the gravity of the clean water in the inner cavity of the dewatering frame 15, the water in the wet paper can be squeezed out by multiple sets of dewatering rollers 5.

[0029] The submersible pump 3 is started to draw clean water from the inner cavity of the dewatering frame 15 and return it to the inner cavity of the water storage frame 21 through the return water corrugated hose 2. This allows for easy adjustment of the amount of clean water in the inner cavity of the dewatering frame 15, which in turn allows for adjustment of the pressing force. When the dewatering frame 15 moves up and down, it can drive multiple sets of T-shaped vertical rods 16 to move synchronously in the inner cavity of the straight vertical pipe 17, thereby restricting the movement path of the dewatering frame 15. Under the action of multiple sets of dewatering holes 14, the pressed water can drip into the inner cavity of the wastewater frame 26. Under the action of the mesh structure of the dewatering nylon cloth 10, the pulp wastewater can be automatically filtered.

[0030] The drive motor 13 is started to rotate the vertical shaft 12 and the agitator 9, thereby agitating the pulp wastewater and enabling it to be fully filtered. The control valve on the drain pipe 11 is opened to discharge the wastewater from the inner cavity of the wastewater frame 26. The pull rings 25 are lifted in sequence to move the connecting block 22 synchronously and separate the insertion hole 24 from the support plate 23, thereby separating the dewatered nylon cloth 10 from the wastewater frame 26, making it easier to clean the filtered debris.
