Description

Technical Field

[0001] The utility model relates to the field of papermaking equipment, and particularly relates to a pulper. Background Art

[0002] In a papermaking system, in order to ensure the quality of the width of the produced paper, it is often necessary to cut off the redundant paper edges according to a preset standard. To improve the utilization rate, these waste paper edges will fall into the steel pulping pool of the waste paper pulper and be shredded and pulped again. The pulping pools of traditional waste paper pulpers are divided into models such as one pool for one machine or one pool for two machines according to the number of machine heads. Among them, for the pulping pool of one pool for two machines, during the operation of the main machine, since the two main machines share one pulping pool, eddies will be generated at the cutter heads of the two main machines respectively. In actual work, the eddies at the two places will cause the flow of the slurry to obstruct each other, affect the flow of the slurry, and reduce the shredding efficiency. Content of the Utility Model

[0003] The purpose of the utility model is to provide a pulper to solve the problem of low cracking efficiency caused by the generation of eddies during the operation of two main machines sharing one pulping pool.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A pulper includes a pulping pool with an upper opening. There are two flange holes on the right side of the pulping pool, which are respectively used for installing a main machine cutter head. The two flange holes are arranged at intervals front and back. A baffle is arranged in the pulping pool. The baffle is arranged vertically. The bottom of the baffle is fixed on the bottom of the pulping pool. The upper part of the baffle is higher than the main machine cutter head. The baffle is located between the two main machine cutter heads.

[0006] Further, the cross-section of the baffle is in a "human" shape.

[0007] Further, the baffle is of a hollow structure and has a cover at the top.

[0008] Further, a spoiler is arranged at the corner inside the pulping pool. The spoiler extends upward from the bottom of the pulping pool along the corner.

[0009] Further, the spoiler is of a hollow structure and has a cover at the top.

[0010] Further, a dilution water injection port and a maintenance manhole are arranged on the left side of the pulping pool.

[0011] Further, a sewage discharge port is arranged at the bottom of the pulping pool, and the sewage discharge port is connected with a sewage discharge pipe.

[0012] Further, an overflow port is arranged on one side of the top of the pulping pool.

[0013] Further, a circulating pulp inlet is arranged above the flange hole on the right side of the pulping pool.

[0014] Furthermore, a liquid level detection port is provided on the right side of the slurry pool, next to the flange hole.

[0015] The beneficial effects of this utility model are:

[0016] A baffle plate is installed in the slurry tank, vertically positioned between the two main cutter heads. The bottom of the baffle plate is fixed to the bottom of the slurry tank, and the top of the baffle plate is higher than the main cutter heads. By placing the baffle plate in this position, the mutual obstruction of eddies when the two main cutter heads are working simultaneously is avoided, thus solving the problem of poor slurry flow. Each main cutter head forms an independent cracking zone, which does not affect each other. At the same time, the slurry in the slurry tank can circulate and crack as a whole, improving the cracking effect and efficiency.

[0017] To further improve the fluidity of the slurry, a baffle plate is installed at the corner inside the slurry tank, extending upward from the bottom of the slurry tank along the corner. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0023] Embodiments of this utility model:

[0024] like Figures 1-2As shown, a pulper includes a pulp tank 1 with an open top. Two flange holes 2 are provided on the right side of the pulp tank 1 for mounting a main cutter head (not shown), the main shaft of which is horizontally positioned. Four support parts 3 are located at the four corners of the bottom of the pulp tank 1. Each support part 3 includes a connecting plate and is fixed to the ground using bolts. The left side wall of the pulp tank 1 is arc-shaped, extending to the bottom of the pulp tank 1. A dilution water inlet 11 is provided on the left side of the pulp tank 1 for adding water to dilute the pulp inside. Near the center, there is also a maintenance manhole 10 for inspection and maintenance.

[0025] The bottom of the slurry tank 1 is equipped with a sewage outlet, which is connected to a sewage pipe 9.

[0026] A circulating slurry inlet 7 is provided on the right side of the slurry tank 1 above the flange hole 2, so that the slurry can be circulated under the action of the material pump.

[0027] A liquid level detection port 6 is provided on the right side of the flange hole 2. The height of the liquid level detection port 6 is set as needed to install a liquid level sensor to detect the liquid level in the slurry tank 1.

[0028] An overflow outlet 12 is provided on one side of the top of the slurry tank 1.

[0029] Two flange holes 2 are spaced apart. A baffle plate 8 is installed in the slurry tank 1. The baffle plate 8 is vertically arranged, with its bottom fixed to the bottom of the slurry tank 1 and its upper part higher than the main cutter head. The baffle plate 8 is located between the two main cutter heads and does not interfere with the rotation of the cutter heads. By setting the baffle plate 8 at this position, the mutual interference of eddies when the two main cutter heads work simultaneously is avoided. Each main cutter head forms an independent cracking area that does not affect the others. At the same time, the slurry in the slurry tank 1 can circulate and crack as a whole, improving the fluidity of the slurry and thus improving the cracking effect.

[0030] The cross-section of the baffle 8 is in the shape of a "V" (human-shaped), but this approximate shape is not an absolute limitation. One side of the baffle 8 is fixed to the inner wall of the slurry tank 1, and the other side has a certain curvature. In other embodiments, a triangular prism profile with a triangular cross-section can also be used; in other embodiments, a circular tube can also be used. The baffle 8 has a hollow structure, and the top of the baffle 8 has a cap 5 to prevent slurry from entering the interior of the baffle 8.

[0031] Furthermore, to improve the slurry flow effect, a baffle plate 4 is provided at the corner inside the slurry tank 1, extending upward from the bottom of the slurry tank 1 along the corner. The baffle plate 4 is a hollow structure, and the top of the baffle plate 4 has a cover 5. The baffle plate can be a rectangular strip, vertically arranged and welded to the corner of the slurry tank 1 (approximately a right-angle structure), or an arc-shaped strip can be used to form an arc-shaped surface or transition plane at the corner, replacing the right-angle structure.
