Description

Technical Field

[0001] This utility model relates to the field of pulp concentration technology, specifically to a recycled pulp inclined wire concentration device. Background Technology

[0002] Pulp thickening is a common operation in papermaking, aiming to treat the pulp to meet the requirements for papermaking. While maintaining paper quality and paper production standards, higher concentrations are generally better. However, the entire papermaking process constantly seeks to find a balance between production needs and cost minimization. Pulp thickening is crucial for the paper industry, as it not only reduces pulp volume and lowers transportation and storage costs but also improves the efficiency of subsequent processes. For example, the concentration for deinking flotation can only reach around 1%. If the concentration is too low, although the effect is good, the volume of pulp processed is too large, consuming excessive energy; if the concentration is too high, although it can increase output, the high concentration can cause fibers to block the ink from floating, resulting in poor deinking. Therefore, the selected pulp is often dehydrated to achieve the concentration required for the next process. Existing patent, patent publication number CN216765410U, discloses an improved multi-wire pulp thickener. The filtration device includes an upper filter, a middle filter, and a lower filter, which are connected end to end and installed at an incline on the frame from top to bottom. The inclination direction of the middle filter is opposite to that of the upper filter, while the inclination direction of the upper filter is the same as that of the lower filter. The filtration accuracy of the upper filter is less than that of the middle filter, and the filtration accuracy of the middle filter is less than that of the lower filter. The pulp collection device is equipped with at least three pulp collection boxes, which are respectively installed below the upper filter, the middle filter, and the lower filter. The pulp collection box installed below the upper filter is located on the same side of the upper filter as the pulp supply device. Triple filtration ensures high concentration, faster pulp supply, and better concentration results. It also reduces filter clogging and the frequency of filter cleaning. The filter is backwashed via a backwashing device, eliminating the need for disassembly and making it more convenient to use.

[0003] Regarding the aforementioned technologies, the inventors believe that the following drawbacks exist: In practical applications, although the filter screen can be backwashed, the equipment needs to be shut down during the backwashing process. If the backwashing operation is not stopped, the filtered pulp will be diluted during the backwashing process, thus affecting the pulp concentration effect. If the filter screen is cleaned after stopping the machine, it will affect the concentration process of the device. Therefore, we propose a regenerated pulp inclined screen concentration device to solve the above-mentioned problems. Utility Model Content
