Description

Technical Field

[0001] This utility model relates to the field of coated paper technology, specifically to a coated paper pulp recycling device. Background Technology

[0002] In the production of coated pulp, the recycling and reuse of excess pulp is a crucial step. However, during the cleaning and filtration process, the filter plates are prone to clogging due to prolonged contact with impurities in the pulp, significantly reducing filtration efficiency. To ensure smooth production, frequent manual unclogging is required, which not only increases labor costs but also severely restricts work efficiency. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a coating pulp recycling device that can improve work efficiency.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a coated pulp recycling device, comprising a cylinder, the innovation of which is: a spiral conveying pipe is provided inside the cylinder, with the top of the conveying pipe being the inlet and the bottom being the outlet, and a drain outlet is provided on the cylinder at the lowest point of each section of the conveying pipe; a spiral receiving pipe is provided outside the cylinder, covering the drain outlet and communicating with it, and a filter screen is inserted at the communication point.

[0005] Furthermore, a drain pipe is provided at the lower end of the receiving pipe, and a shut-off valve is provided on the drain pipe.

[0006] Furthermore, a cleaning door is provided at the bottom of the conveying pipe.

[0007] Furthermore, a support leg is provided at the bottom of the conveying pipe, and the support leg is fixedly connected to the inside of the cylinder.

[0008] The beneficial effects of this utility model after adopting the above structure are as follows:

[0009] This utility model separates impurities by setting up a spiral conveying pipe and receiving pipe, and connecting them to a drain port and a filter. At the same time, the filter screen adopts a plug-in structure, which makes it easy to pull out and replace a batch of new filter screens, thereby improving work efficiency. The replaced filter screens can be cleaned and reused. Attached Figure Description

[0013] The present invention will be further described below with reference to the accompanying drawings.

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model.

[0015] See Figure 1 A pulp recycling device includes a cylinder 1, with a spiral conveying pipe 2 inside the cylinder 1. The top of the conveying pipe 2 is a liquid inlet 3, and the bottom is a liquid outlet 4. A drain outlet 5 is opened at the lowest point of each section of the conveying pipe on the cylinder 1. A spiral receiving pipe 6 is provided outside the cylinder 1, covering the drain outlet 5 and communicating with it. A filter screen 7 is inserted at the communication point. Specifically, when the recycled coated pulp needs to be cleaned and filtered, the coated pulp enters the conveying pipe 2 through the inlet 3. As the coated pulp flows along the conveying pipe 2, it is conveyed through the outlet 5 and the filter screen 7 to the receiving pipe 6, and finally output through the receiving pipe. At the same time, as the coated pulp flows, some impurities will accumulate at the bottom of the conveying pipe 2. The filter screen 7 adopts a plug-in structure, and a slot is opened on the receiving pipe 6. The filter screen 7 is inserted into the slot, which makes it easy to pull out and replace a new batch of filter screens, thereby improving work efficiency. The replaced filter screens can be cleaned and reused.

[0016] In this embodiment, a drain pipe 8 is provided at the lower end of the receiving pipe 6, and a shut-off valve 9 is provided on the drain pipe 8. The coated pulp in the receiving pipe 6 is finally discharged from the drain pipe 8, which can be opened and closed by the shut-off valve 9.

[0017] In this embodiment, a cleaning door 10 is provided at the bottom of the conveying pipe 2. By opening the cleaning door, impurities inside the conveying pipe 2 can be cleaned.

[0018] In this embodiment, a support leg 11 is provided at the bottom of the conveying pipe 2, and the support leg 11 is fixedly connected to the inside of the cylinder 1. The support leg 11 supports the conveying pipe 2 and the cylinder 1 at the same time, improving stability.

[0019] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
