[0021] In the following description, embodiments of the papermaking pulp pressing equipment of the present invention will be described with reference to the accompanying drawings.

[0022] Figure 1-5 This invention illustrates a paper pulp pressing device according to an embodiment of the present invention. It includes a support frame 1, a pressing roller 2 fixedly mounted on the top left side of the support frame 1, a discharge port 3 connected to the left side of the pressing roller 2, a water tank 4 installed at the bottom of the inner cavity of the support frame 1, two symmetrical support legs 5 fixedly connected to the bottom of the water tank 4, the two support legs 5 being fixedly connected to the lower base plate of the support frame 1, two symmetrical fixing plates 6 fixedly connected to the top of the inner cavity of the support frame 1, two symmetrical connecting plates 7 fixedly connected to the opposite side of each of the two fixing plates 6, a collecting mesh 8 installed on the opposite side of each of the two connecting plates 7, L-shaped plates 9 fixedly connected to the left and right sides of the collecting mesh 8, the opposite sides of the two L-shaped plates 9 fitting against the two fixing plates 6, and two symmetrical limiting bolts 10 penetrating through the top of each of the left and right connecting plates 7. The limiting bolt 10 extends through the surface of the L-shaped plate 9 and fits against the bottom connecting plate 7. The limiting bolt 10 limits the L-shaped plate 9 fixedly connected to both sides of the collecting net 8, preventing the pressing roller 2 from vibrating during operation and causing the collecting net 8 to shift out of the two connecting plates 7, thus improving the stability of the collecting net 8. A water inlet trough 11 is installed on the right side of the top of the water tank 4. The front and rear ends of the water inlet trough 11 are suspended from the top of the water tank 4. A filter screen 12 is installed at the central axis at the bottom of the water inlet trough 11. A collecting box 13 is set at the bottom of the discharge port 3. The collecting box 13 is fixedly connected to the left side of the support frame 1. A push plate 14 is slidably connected to the bottom of the collecting box 13. A water pipe 15 is connected to the bottom of the front side of the water tank 4. A valve 16 is fixedly installed on the front side of the water pipe 15. The rear end of the valve 16 extends through the inner cavity of the water pipe 15.

[0023] Working Principle: In use, the pulp raw material to be pressed enters the press drum 2 through the feed inlet. The drive system drives the press drum 2 to rotate. The squeezing action between the drums achieves solid-liquid separation of the pulp. During the pressing process, the pulp flows through the gaps in the press drum or the gaps in the pulp to the water tank 4 below. Simultaneously, some potentially leaking pulp falls onto the collection screen 8 under gravity and the inertia of the equipment. The collection screen 8 is installed in a support structure composed of a fixed plate 6 and a connecting plate 7. The collection screen 8 intercepts leaking pulp, preventing the raw material from flowing directly with the liquid. The intercepted pulp is temporarily retained on the surface of the collection screen. Later, the collection screen 8 is removed and the pulp is contained within it. The raw materials are collected in the collection bin 13 to achieve recycling and reuse. Before the separated liquid falls into the water tank 4, it will pass through the filter screen 12, which is installed at the water inlet trough 11. Since the filter screen 12 is removable, it can be removed for cleaning when the collection of impurities is slow. The liquid is filtered to remove residual fibers and impurities, ensuring the cleanliness of the liquid flowing into the water tank 4, which is convenient for subsequent water resource recycling. The filtered liquid is stored in the water tank 4 and can be transported to the designated stage as needed through the control of the water pipe 15 and the valve 16 to achieve secondary utilization of water resources and reduce discharge and waste. The pressed pulp is discharged through the discharge port 3 and enters the inner cavity of the collection bin 13.

[0024] In summary, this paper pulp pressing equipment uses a pressing drum 2 to squeeze and press the raw material, a filter screen 12 to filter the liquid flowing out of the pressing drum 2, a water tank 4 to store the filtered liquid, a fixed plate 6, a connecting plate 7, and a collecting net 8 to collect the pulp left over during the pressing process, and finally a collecting bin 13 to collect the pulp. This achieves the goals of integrating raw material recovery and water resource recycling, intercepting leaked pulp to avoid waste, recovering and separating liquid for secondary use, and stabilizing the pressing process to ensure production quality.
