[0010] Further, the abutment surface of the half-pan body is provided with a clamping groove for accommodating the sealing strip.

[0011] Further, the bottom side of the half-pan body is provided with an ear plate, the two half-pan bodies are connected by bolts, and the sealing strip is pressed.

[0012] Further, the inner side surface of the water pan is coated with an anti-fouling coating.

[0013] The utility model has the beneficial effects that:

[0014] The utility model discloses a two-lip type water pan, and one side half disc body can be independently installed and disassembled during installation and disassembly, and other mechanisms of the pulper do not need to be disassembled.

[0015] Further, the abutting place of the two half disc bodies is provided with a sealing strip, and the sealing strip can be extruded by the pressing force when the two half disc bodies are connected, so that the sealing property of the connecting place is ensured, and water leakage is prevented.

[0016] Further, the inside of the water pan is provided with an antifouling coating, water and dirt are difficult to adhere to the surface of the water pan, cleaning and maintenance are facilitated, corrosion resistance is higher, and the cost of replacing the water pan is reduced.

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art belong to the protection scope of the utility model.

[0024] Embodiments of the utility model:

[0025] As shown in the drawings, Figures 1-4 The utility model discloses a pulper water pan, and the water pan is split type, that is, two-lip type structure, instead of the existing integrated structure, to achieve the purpose of convenient disassembly and assembly. The water pan comprises two half disc bodies 1 that are connected to each other, and the half disc bodies 1 are made of 304 stainless steel.

[0026] The butt joint surface side of the half disc body 1 is provided with a semicircular hole 6, and the semicircular holes 6 of the two half disc bodies 1 are butted to form a mounting clearance hole 5 (a circular hole). That is, during installation, the two half disc bodies 1 are respectively installed from the radial side of the stirring main shaft of the pulper, and after installation, the stirring main shaft passes through the mounting clearance hole 5.

[0027] The bottom of the half disc body 1 is provided with three bolt holes 2, and the bolt holes 2 on the half disc body 1 are distributed around the semicircular hole 6. The half disc body 1 is fixed on the bearing pressure cover (corresponding to the transmission mechanism part described in the background art) by bolts.

[0028] The butt joint surface of the half disc body 1 is provided with a clamping groove 8 for accommodating the sealing strip (not shown in the figure), such as a rubber strip. The bottom side of the half disc body 1 is provided with an ear plate 3 for the bolt to pass through, and the two half disc bodies 1 are connected by bolts. After connection, the sealing strip can be squeezed to ensure the sealing of the butt joint and prevent water leakage. In other embodiments, the half disc body can not be provided with a clamping groove, and the sealing strip is pre-attached to the butt joint surface of one of the half disc bodies.

[0029] The bottom center of the water pan is upwardly convex, and a ring cavity 7 is formed at the edge position. The outer circumferential side of the water pan is provided with a drain port 4, which is close to the lower part of the water pan and communicates with the ring cavity 7. The water received by the water pan flows into the ring cavity 7 along the edge of the convex part, and is discharged through the drain port 4. The drain port 4 shown in the figure is a drain pipe head, which can be further connected to a water pipe to discharge water to a suitable position.

[0030] Further, a stain-resistant coating is applied to the inner side surface of the water pan, which has very low surface tension, so that water and dirt are difficult to adhere to the surface of the water pan, thereby facilitating cleaning and maintenance, and also prolonging the service life of the water pan. The stain-resistant coating is a material in the prior art, and here is only an application.

[0031] During installation and use of the pulper water pan, one of the half disc bodies 1 is connected to the bearing pressure cover (the transmission part of the pulper) by bolts, and a sealing strip is inserted into the clamping groove 8 of the half disc body 1. The length of the sealing strip is enough to cover the end face of the clamping groove 8 of the half disc body 1. Then, the other half disc body 1 is installed, and after butt joint, the other half disc body 1 is fixed on the bearing pressure cover by bolts. Then, the two half disc bodies 1 are butted together and tightly fitted by using two bolts in the two ear plates 3, so that the sealing strip is squeezed, thereby ensuring the sealing.
