Problems solved by technology

High-quality waste paper recycling technology has not yet been fully developed and matured in my country, and the imported production equipment has a complex structure and high price, which cannot fully adapt to the production environment in my country
The difficulty of waste paper recycling lies in the pulping process of waste paper. Due to the lack of suitable supporting equipment, the existing technology cannot convert waste paper into fine pulp with high efficiency and high quality, and ultimately the quality of the recycled paper cannot be guaranteed.

Embodiment 2

[0070] like figure 1 and 5 As shown, the present invention also includes a slurry flow device. The slurry flow device is arranged in the right end standpipe of the fine slurry channel; the slurry flow device includes a flow slurry stirring motor, and the motor shaft of the flow slurry stirring motor is connected to a lifting agitating channel, and the lifting agitating channel is vertically arranged In the standpipe at the right end of the fine slurry channel; on the left side wall of the standpipe at the right end of the fine slurry channel, the first flow bar hole, the second flow bar hole and the third flow bar hole are sequentially opened from top to bottom. The first flow slurry guide tube, the second flow slurry guide tube and the third flow slurry guide tube are installed in the right order of the first flow slurry bar hole, the second flow slurry bar hole and the third flow slurry bar hole; The slurry guide pipe, the second slurry guide tube and the third slurry guid...

Embodiment 3

[0075] In this embodiment, the first water source is a clean tap water source.

[0076] The second water source is a water source that is reused after filtration of recycled water in the papermaking process; the recycled water in the papermaking process includes filtered water after pulp washing and drained water from the papermaking net blanket. like figure 1 As shown, the draining water of the papermaking net blanket is temporarily stored in the draining recovery tank, and the draining outlet is opened in the draining recovery tank, and the water inlet end of the draining outlet pipe is installed at the draining outlet, and the draining outlet pipe is connected to the water spray pipe through the draining outlet pump. The water inlet, the water inlet of the power outlet pipe and / or the water inlet of the pulp wash flush pipe.

[0077] The filtered water after pulp washing is transported to the top of the vibrating sieve through the pulp washing and filtering water recycling...

Abstract

The invention relates to an efficient environment-friendly papermaking production line, belonging to the technical field of papermaking mechanical equipment. The efficient environment-friendly papermaking production line is characterized by comprising pulping equipment, wherein a feeding device of the pulping equipment can feed waste paper raw materials into a coarse crushing device; the coarse crushing device can crush the waste paper raw materials into coarse paper pulp; the coarse paper pulp is conveyed into a screening device through water flow assistance; the coarse paper pulp enters a pulp washing device after being screened and filtered by the screening device; and the pulp enters a fine grinding device after being cleaned by the pulp washing device, and enters a storage device after being finely ground by the fine grinding device. According to the invention, fine paper pulp can be finally obtained through automatic feeding, coarse crushing, paper material circulating and infiltrating, screening and paper scrap grinding and refining, and is stored for papermaking operation.

Description

technical field [0001] The invention relates to a high-efficiency and environment-friendly papermaking production line, which belongs to the technical field of papermaking machinery and equipment. Background technique [0002] Waste paper is an important renewable resource, and the recycling of waste paper is an effective way to solve the three major problems faced by the paper industry, such as shortage of raw materials, energy shortage and serious pollution. High-quality waste paper is also called secondary fiber. Recycling secondary fiber as a raw material for papermaking can reduce the use of a large amount of wood and is conducive to environmental protection. Generally speaking, 1 ton of high-quality waste paper can produce about 800 kg of paper, save 2-3 tons of wood, save electricity by 1000 kW·h, and save water by 50 m 3 . High-quality waste paper recycling technology has not yet been fully developed and matured in my country, and the imported production equipment ...
