Problems solved by technology
At present, most of the coarse screens produced in my country adopt the design of a single screen drum and a cylindrical shell structure. During use, it is found that this type of coarse screen has poor screening effect, high energy consumption, low production efficiency, and easy to block the screen holes. Difficult to clean and replace

The invention discloses a novel rough screening device for papermaking. The novel rough screening device comprises a first screen, a second screen, a pulp channel, a pulp inlet and a pulp outlet. The pulp channel is provided with the pulp inlet and the pulp outlet and is distributed obliquely. The pulp inlet is located in the upper portion of the pulp channel. The pulp outlet is located in the lower portion of the pulp channel. Two parallel clamping grooves are formed in the pulp channel and internally provided with the first screen and the second screen respectively. Slag collecting grooves are formed in the first screen and the second screen. A flow velocity measuring instrument is arranged at the pulp outlet. The first screen and the second screen are the same screens. The first screen is located at the upper portion of the second screen. The first screen and the second screen are vertically arranged. The included angle between the pulp channel and the horizontal plane is 5-15 degrees. On the whole, the novel rough screening device has the advantages that the screening effect is good, production efficiency is high, and the screens are easy to replace and clean.
Description
technical field [0001] The invention belongs to the technical field of special equipment for papermaking and pulping, and relates to a novel coarse screen equipment for papermaking. Background technique [0002] In the paper pulping system, the screening and slag removal link is very important. The screening degree of the pulp directly affects the quality of the paper, and then affects the production efficiency and profit of the enterprise. The coarse screen is placed in the fine screen and screen in the pulping system. Commonly used screening equipment before the sieve is used to remove larger impurities in the pulp. At present, most of the coarse screens produced in my country adopt the design of a single screen drum and a cylindrical shell structure. During use, it is found that this type of coarse screen has poor screening effect, high energy consumption, low production efficiency, and easy to block the screen holes. Not easy to clean and replace. Contents of the inven...
