Abstract

The invention provides a vacuum box body of a vacuum touch roll for a papermaking machine. The vacuum box body has the advantages of simple structure, convenient maintenance, and stable and good dehydration effect. The vacuum box body comprises a vacuum box which is arranged inside a roll body; two ends of the vacuum box are respectively connected with a vacuum box head; and one end of one side of vacuum box heads is connected with a vacuum suction port. The vacuum box body is characterized in that a plurality of water suction ports are uniformly and axially arranged on the vacuum box; the vacuum box close to the inner wall end of the roll body is provided with sealing devices which can enclose the water suction ports and cooperate with the vacuum box to form a vacuum chamber; the vacuum box comprises a semi-circular top part and a semi-hexangular bottom part; the side wall of the vacuum box is provided with water jets used for spraying water to the inner wall of the roll body; the water jets are respectively arranged on two side walls of the bottom part of the vacuum box; water-jet pipes are arranged on an operation-side vacuum box head and connected with water jets; and a rolling wheel device is arranged under the bottom part of the vacuum box.

Description

Technical field [0001] The invention relates to the technical field of papermaking equipment, in particular to a vacuum box of a vacuum roller of a papermaking machine. Background technique [0002] After the pulp is uniformly processed in the papermaking process, due to the large amount of moisture in the pulp, the paper needs to be pressed to remove the moisture during the forming process of the paper product. The vacuum roll is a commonly used part of the paper machine for dehydration, which affects the paper forming, dehydration and paper machine The speed of the vehicle plays a decisive role, and also plays a key role in the physical properties, optical properties, and printability of the paper. The existing vacuum box of the vacuum roll has the following problems: the structure of the vacuum box is complicated due to the provision of multiple vacuum zones, the manufacturing and use costs are expensive, and the vacuuming effect is not satisfactory. Summary of the invention ...
