Embodiment Construction

[0047] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0048] like figure 1 , figure 2 and image 3 As shown, a thickening tank includes a tank body 1, a rotating shaft 2 and a double-headed spiral stirring member.

[0049] In this embodiment, an opening is provided on the upper part of the tank body 1, and a feeding screw 3 is installed for feeding materials. The difference from the tank body of the traditional thickening tank is that in order to adapt to the condition of a relatively high slurry concentration in the straw papermaking process, The bottom of the tank body 1 is provided with an inclined bottom surface 4, and the lower edge of the inclined bottom surface 4 is provided with a discharge notch 5, and the angle between the inclined bottom surface 4 and the horizontal plane is 10-45 de...

Abstract

The invention discloses a thickening tank, which comprises a tank body, a rotating shaft and a double-headed spiral stirring member. The upper part of the tank body is provided with an opening and a dilution screw is installed. The bottom of the tank body is provided with an inclined bottom surface, and the lower part of the inclined bottom surface There is a discharge slot on the edge; a universal joint is installed on the upper end of the rotating shaft, and the power output shaft of the driving equipment is connected by the universal joint. The bottom center of the tank is provided with a seat cover for installing the free end of the rotating shaft. For the movable ball, the free end of the rotating shaft is provided with a groove matching the ball, and the groove is clamped outside the ball so that the free end of the rotating shaft can be adjusted in the remaining space of the seat cover to realize the axis position adjustment; the double-headed spiral stirring piece is composed of Two helical blades with the same direction of rotation are coiled on the rotating shaft. The invention has a reasonable structure, can meet the requirement of high slurry concentration in the straw papermaking process, is easy to discharge, ensures uniform mixing of reagents and slurry in the tank, and improves the quality of the final product.

Description

technical field [0001] The invention relates to papermaking raw material processing equipment, in particular to a thickening tank especially suitable for adding reagents or adjusting the concentration of slurry with relatively high concentration in the straw papermaking process. Background technique [0002] At present, wood is generally used as the main raw material in the paper industry, but with the further deterioration of the environment, this process of using logs as raw materials is gradually being replaced. In order to meet the needs of the paper industry to the greatest extent, there are now gradually emerging The technology of wool grass, cotton stalks, reeds, corn stalks, straw and other grasses as raw materials for pulping not only provides a new fiber source for the paper industry, but also realizes the utilization of waste, changing the original above-mentioned materials that can only be incinerated. Or returning to the field, the comprehensive utilization of r...
