Rotary drum type screening joint machine

Abstract

The invention relates to a rotary drum type screening joint machine, and belongs to the field of papermaking concentration filtering equipment. The rotary drum type screening joint machine comprises a base, the base is provided with a motor and a cylinder, a rotating shaft is fixedly arranged in the cylinder, the bottom of the rotating shaft is connected with the motor through a belt, the top of the rotating shaft is connected with a rotating plate through a connecting piece, the rotating plate is connected with the top of a screen cylinder, the screen cylinder is arranged on the outer side of a rotating shaft sealing device in a sleeving mode, a fixing rib is arranged on the inner side of the screen cylinder, the fixing rib is fixed to the rotating shaft sealing device through a fastener, a guiding connecting piece is arranged corresponding to the bottom of the screen cylinder and connected with a fixing ring at the lower portion of the cylinder, a lower cavity is formed by the guiding connecting piece, the fixing ring and the lower portion of the cylinder, the lower cavity is communicated with a pulp outlet, an upper cavity is formed by the guiding connecting piece, the fixing ring, the screen cylinder and the upper portion of the cylinder, and the upper cavity is communicated with a pulp inlet and a slag outlet. The rotary drum type screening joint machine is compact in structure, easy to operate, low in energy consumption, thorough in rough slag screening and free of the rough slag winding phenomenon.

Description

technical field [0001] The invention relates to a rotary drum screen section machine, which belongs to the field of paper-making thickening and filtering equipment. Background technique [0002] At present, thickening and filtering equipment has become a crucial link in papermaking and pulping equipment, but the coarse slag rate of ordinary sieve drum equipment is relatively high, and impurities such as gravel and metal blocks are difficult to completely remove during equipment operation. Clearing will seriously affect the pulping quality of the subsequent equipment. During the operation of the equipment, the screen drum is very prone to blockage, which will not only increase the current of the motor, but also cause the pressure of the pulp outlet pipe to drop. Contents of the invention [0003] According to the deficiencies in the prior art above, the problem to be solved by the present invention is to provide a rotary drum screen section machine with compact structure, s...
