Adjustable box-type pulp concentrating device

Abstract

The invention discloses an adjustable box-type pulp concentrating device which comprises a homogenate box and a dewatering screen device, wherein the homogenate box is provided with a pulp inlet pipe; the dewatering screen device is connected with the pulp outlet of the homogenate box; the homogenate box is internally provided with a partition plate used for uniformly adjusting the concentration and distribution of pulp which enters a box body; the pulp outlet of the homogenate box is formed by an adjustable plate movably articulated with the homogenate box and a bottom plate of the homogenate box; and the outer side of the homogenate box is provided with an adjusting bolt used for adjusting the opening angle of the adjustable plate. The adjustable box-type pulp concentrating device disclosed by the invention can realize the high-efficiency concentration of the pulp and is large in adjustable amplitude of concentrated concentration. Compared with the traditional concentration equipment, the adjustable box-type pulp concentrating device disclosed by the invention has the advantages of less equipment input, low energy consumption, convenience for concentration control and high concentration efficiency.

Description

technical field [0001] The invention relates to a solid-liquid two-phase thickening technology, in particular to an adjustable box-type pulp thickening device. Background technique [0002] At present, pulping and papermaking technology mostly operates in a low-consistency (3-5%) state, but in the long-term production and use process, people have discovered many disadvantages of low-consistency papermaking technology, such as: low production efficiency, high power consumption, The product quality is poor, the occupied area is large, etc. In view of this, the pulp and papermaking technology has become an inevitable trend in the development of the paper industry from low-consistency to medium- and high-consistency technology. Papermaking technology can significantly improve product quality, save energy consumption and greatly increase production efficiency. However, when the traditional low-consistency technology is developed into the medium-high consistency technology, the p...

Problems solved by technology

[0003] In terms of current concentration methods and equipment, two concentration methods and equipment, natural dehydration or forced dehydration, are generally used in production. Natural dehydration equipment, such as inclined screens, has the advantages of low energy consumption and simple manufacture. The capacity is relatively small, and the concentration parameters are relatively difficult to control; forced dehydration equipment such as cylinder thickeners, screw dehydrators, belt presses, etc., these dehydration equipment have the advantages of relatively high concentration and large concentration capacity, but forced Concentration methods and equipment have relatively high energy consumption, high equipment investment and operating costs, and difficult maintenance, etc., especially not suitable for many small and medium-sized enterprises.
