[0004] Aiming at the deficiencies of the prior art, the present invention provides a device for automatically adjusting the amount of pulp entering during the working process of the pressure screen, which can automatically detect whether the flow of pulp in the positive and negative pressure areas is balanced, so as to automatically adjust the pulp inlet Rotate the opening degree of the valve, so that the pulp flow in the positive and negative pressure areas is balanced, without manual adjustment, which saves time and improves efficiency, and does not affect the filtering effect. Whether the flow of pulp in the positive and negative pressure areas formed by the pressure screen rotor is balanced to automatically adjust the size of the incoming pulp, resulting in unbalanced pulp in and out of the positive and negative pressure areas, causing blockage, affecting the filtering effect, and manual adjustment is time-consuming and laborious The problem

The invention relates to the technical field of pressurized screens, and discloses a device for automatically adjusting the amount of pulp entering a pressurized screen in a working process. The device comprises a screen drum, wherein a rotor is arranged on the left side of the screen drum; a matching groove is formed in the screen drum; a permeation plate is slidably connected to the interior of the matching groove; a sliding bin is fixedly connected to the surface of the permeation plate; a dielectric plate is arranged in the sliding bin; and a positive plate is arranged on the upper side of the dielectric plate. According to the device for automatically adjusting the amount of the pulp entering the pressurized screen in the working process, through cooperative use of the screen drum, the rotor, the matching groove, a reel, a pull wire and the like, whether flowing of paper pulp in positive and negative pressure areas is balanced or not can be automatically detected, the opening degree of a pulp inlet rotating valve is automatically adjusted, and therefore, flowing of the paper pulp in the positive and negative pressure areas is balanced; and manual adjustment is not needed, so time is saved, efficiency is improved, and filtering effect is not affected.
Description
technical field [0001] The invention relates to the technical field of pressure sieves, in particular to a device for automatically adjusting the amount of slurry entering during the working process of the pressure sieve. Background technique [0002] In the process of paper making and pulping, the pressure screen is often used to filter the impurities in the pulp, but the existing pressure screen cannot be automatically controlled according to whether the flow of the pulp in the positive and negative pressure areas formed by the pressure screen rotor is balanced during the working process. Adjusting the size of the incoming pulp will result in unbalanced pulp flow in and out of the positive and negative pressure areas, causing blockage and affecting the filtering effect, and manual adjustment is time-consuming and laborious. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the present invention provide...
