The manual screening platform 26 is a belt conveyor structure. / The processing method of the present invention, that is, the system production process is as follows: · The pulp waste residue is quantitatively fed into the drum screen 2 2 by the weigh feeder 2 1 for preliminary selection, and the sieved small particle impurities fall on the belt conveyor 23 And is sent to the waste bin 24. The roller screen 2 2 sieves out some of the small particle impurities in the pulp residue and then sends it to the magnetic separator 2 5 ' to separate the ferromagnetic impurities in the pulp residue. Then, the sorted pulp waste is sent to the artificial screening platform 26', and large pieces of impurities such as wood and stones are easily picked up by hand.

Then, after passing through the hand k, the slag slag system is then sent to the air separation separator 2 through the belt conveyor 27, and the ventilator will sort the impurities with different specific gravity to the groove with different distance from the air separator. In this way, metal, silt, wood, plastic, etc. can be separated one by one to further reduce the pressure on the subsequent process. Then, the relatively clean pulp waste is sent to the pulverizer 30 through the belt conveyor 29 for pulverization, since the pulverizer 30 does not have large stones, wood,

V. INSTRUCTIONS (15) Cloth, metal and other plastic-free impurities that are easy to lift are separated; as a result, the downstream process can be greatly reduced in energy consumption and in metal or other large blocks of miscellaneous 'It can greatly reduce the energy consumption and wear of the crusher components. Then, the pulverized pulp waste slag enters the first open type separator = the immersed spray water soaking and the screw feed rod stirring after the smashing, the spray water and the screw feed rod are arranged therein. It is possible to separate β into paper fibers (discharged from the bottom screen of the first open separator 31). Machine 32: The stripped pulp residue is sent to the pulper 32, and is dispersed in the liquid in the slurry = crumb paper, and the plastic is modified. When the sandstone or metal in the collapsed concrete sinks to the bottom metal, the sediment is discharged in a large amount, and the liquid is treated with water to treat the inlet of W0B. Thus, it can be escaped - abundance of ice / day, followed by separation has been completed; fiber 2 plastic separation. - The retreat of some paper fiber plastics

PP, PE, 〇pp plastic, need to recycle, 7 flat artichoke 35. The plastic will float on the water surface, while the other weight is less than water, so this part is in the water, so this part of the plastic will be slow = the material is more than a large spiral than the upper part of the trough; The continuous flotation of the horizontal flotation promotes the shedding of the paper fibers, and moves the floating material on the water surface to the outside. The width of the water tank can be changed to a small gradient, and a narrow aggregate is formed. Close to the bottom is the concentration of the bottom; the bottom slab b7 of the collecting trough 357, which can facilitate the sediment to finally sink to the bottom of the flotation cell 栌 =, the scraper transport 353, the trough 357 - end, and The waste from the collecting tank ^ is slowly pushed into the aggregate and then installed in the waste well 358 of the pass-through waste well 358 / ^, followed by the waste into the single-stage hoist 359 - : divided into pulp' and the material along with it. At 35:2, the inevitable concentration of pulp will increase continuously. Into a single level horizontal flotation cell

In order to solve this problem, in this embodiment, two sets of water treatment device 3512 and a water treatment device 3513 are installed for the single-stage horizontal flotation tank, and the crucible is used to reduce the pulp concentration in the single-stage horizontal flotation tank to ensure the production process can be Normally continuous. Subsequently, the plastic floated from the single-stage horizontal flotation cell 35 is fed to the plastic storage bin 39 via the third open separator 38. Finally, a plastic material which can be reused is produced by the granulator 40. That is, the present invention provides the following improvements to the existing system:

1. Magnetic separation is added behind the drum screen in the primary selection process, and ferromagnetic debris is discharged at a relatively small energy cost. 2. The artificial screening platform has been added to separate large pieces of metal, stone, wood, textiles and other impurities as much as possible to reduce the load failure rate of the crusher. '3. After the manual screening platform, a wind selection process is added to separate the light and heavy impurities in the scrap. Further reducing the power and water consumption of the subsequent process, adding a μ 搓揉 rolling screen behind the water hydrating machine (for the well-known technology) can search for scattered plastic fragments; ten:=;: on-chip Paper fiber. The last = material: The burden of the system: excessive paper fiber will increase the granulated plastic raw materials and become waste. After the production is taken out: (1; using the structure of the groove and the flotation process is specifically for the ten/pre-passing tank instead of the multi-stage stepping flotation tank, avoiding

Page 21 1274800 V. Description of the invention (18) The number of high-slap times of the multi-stage stepped trough at the bottom of the isolated sub-tank, the single-stage horizontal flotation pushes the suspension process in the water, the drift affects the working efficiency width to be close to the bottom trough, ie the upper width At the same time, the characteristics of the flotation tank in the collecting tank to the hoist or spiral in the collecting tank have no material accumulation in the water treatment system, and the permeate concentration will increase the flotation efficiency and reduce the system. The problem that the efficiency of the suction operation of the Sydney pulp waste residue having at least the system of the present invention is too low is to cause the wrestling effect of the debris during the falling process, and facilitate the separation of the adhered mixture. In the upper part of the hair trough, a plurality of spiral pendulum propellers are added, and one side of the trough is slowly moved forward in the floating object to solve the problem of the prior art: == the floating object frequently generates on the upstream side of the sub-tank junction; (3) The cross-section of the single-stage horizontal flotation cell of the present invention is gradually reduced, and a slanting form is formed at the bottom of the grazing 卩, and a waste well is provided at the end of the sump. The bottom 4 is equipped with a chain scraper transporter. According to the single-level level, the key scraper transporter can push the milking material to the waste well at a slow speed, and then the bucks transported by the Dantian calendar The machine is taken out to keep the single 弋 '(4) for the water hydrating machine and the single-stage horizontal flotation tank. * It can be used to quickly reduce the water from the slurry machine and the single-stage horizontal flotation tank. The county floats low SS indicator = Qingshui re-send back to single-level horizontal flotation f. At the same time, the water of the single-stage horizontal flotation tank can be used: the water quantity and the sewage discharge amount are used for the clothing. The present invention has the following advantages compared with the prior art: + ^ The main function is to recover the plastic in the pulp waste, then There are two aspects to the benefits of Hengji—the rate of plastic recovery: f: the number of plastics that can be recycled

The process of the present invention and the structure of the related facilities make the recycled water consumption of the prior art technology less. The present invention proposes a: "Pure plastic is more pure" and the energy and the plastic recycling are very strong: : Process and structure, and 1, the energy consumption per ton of pulp waste. The details are as follows. The primary selection stage uses magnetic separation and air selection, so the shell is lower. Since the present invention removes metal debris, sand and stone, and can separate the 1 = smaller energy consumption, the recycled matter is more valuable. Iron and non-ferrous gold in the debris 2. The equipment has a longer life and less maintenance. Before the crushing, the hand selection is increased. Since the present invention is in powder, the load of the pulverizer can be effectively reduced, and: J: The selection of the block debris reduces the maintenance cost. k has a long life of equipment, and 3, the quality of recycled plastic is better.
