Description

Technical Field

[0001] The present invention relates to the field of papermaking, in particular to a pulp-residue separation device after pulping in papermaking. Background Art

[0002] When making paper, wood and other raw materials need to be pulped. The wood pulp fibers are small and can be used for papermaking, but the wood tendons, bark and other waste residues need to be filtered out. However, due to the slender structure of the wood fibers and their interweaving with the waste residue, it is difficult to separate them. Usually, after one filtration, there are still a large amount of usable wood fibers in the waste residue, and a large amount of water is needed to repeatedly impact and filter them to completely separate them. The traditional screening method has low separation efficiency. In addition, since the wood fibers are intertwined with each other, it is easy to form compaction on the filter screen and clog the filter screen. The mesh of the traditional filter screen is square, which is difficult to clean after use. Summary of the Invention

A mounting groove 103 is provided at the left front end of the pulp pipe 1. Threaded rods 105 are fixed at the four corners of the mounting groove 103 on the pulp pipe 1, and hexagonal nuts 106 are connected to the threaded rods 105 through threads. After the screen plate 202 is inserted into the slot 104, the slag pipe 3 of the first cover 102 is passed through the mounting hole 201, and then the hexagonal nut 106 is screwed on the mounting groove 103 to press the sealing plate 2 onto the mounting groove 103 to complete the installation. A slot 104 is provided in the middle of the mounting groove 103 in the pulp pipe 1.

[0028] The filtering mechanism includes a sealing plate 2 and a movable plate 207. The four corners of the sealing plate 2 are respectively provided with mounting holes 201. A sieve plate 202 is fixed to the middle of the rear side surface of the sealing plate 2. No less than thirteen sieve slots 203 are equidistantly provided on the sieve plate 202. Threaded holes 205 are respectively provided at the four corners of the sieve plate 202. A sliding rod 204 is connected to the threaded hole 205 through a thread. The left end of the sliding rod 204 is provided with a thread. When installing the sieve plate 202, the sliding rod 204 can be rotated by a wrench to adjust the length of the sliding rod 204 to facilitate loading and unloading of the sealing plate 2. A clamp 206 is fixed to the right end of the sliding rod 204.

[0029] Sliding holes 208 are respectively opened at the four corners of the movable plate 207, a leakage hole 209 is opened in the middle of the movable plate 207, and no less than thirteen plug plates 210 are fixed at equal intervals on the left side of the movable plate 207.

[0030] The slide rod 204 is slidably connected in the slide hole 208 , and elastic bands 211 are fixed symmetrically on the upper and lower middle parts of the left side of the movable plate 207 . The left end of the elastic band 211 is fixed on the sieve plate 202 , and the fixed position of the insert plate 210 corresponds to the sieve slot 203 .

[0031] The threaded rod 105 is slidably connected in the mounting hole 201 , and the sieve plate 202 is snap-fitted into the slot 104 .

[0032] The power mechanism includes a slag pipe 3 and a feed pipe 307. The slag pipe 3 is connected to the left side of the pulp pipe 1. The middle left side of the slag pipe 3 is connected to the slag discharge pipe 302. The second cover 303 is connected to the slag discharge pipe 302 through a threaded seal. The left end of the slag pipe 3 is vertically connected to the power pipe 301. An electric telescopic rod 304 is fixed to the middle of the top of the power pipe 301. An air hole 305 is provided at the top of the power pipe 301. A piston 306 is fixed to the telescopic end of the lower end of the electric telescopic rod 304. The piston 306 is slidably connected in the power pipe 301. The feed pipe 307 is vertically connected and fixed above the left end of the pulp pipe 1.

[0033] The reflux mechanism includes a vertical reflux pipe 4, which is vertically connected and fixed on the upper right side of the pulp pipe 1. The upper left end of the vertical reflux pipe 4 is vertically connected to a horizontal reflux pipe 401. The left end of the horizontal reflux pipe 401 is connected and fixed on the feed pipe 307. A canvas layer 402 is fixed inside the connection between the vertical reflux pipe 4 and the horizontal reflux pipe 401, and a one-way valve 403 is installed inside the connection between the horizontal reflux pipe 401 and the feed pipe 307.

[0034] The height of the power pipe 301 is the same as that of the feed pipe 307 , and the height of the vertical return pipe 4 is half of the height of the power pipe 301 and the feed pipe 307 .

[0035] A rubber strip is fixed to the rear side of the sealing plate 2 , and a sealing ring is fixed to the side of the piston 306 , so that the piston 306 has better sealing performance when moving up and down in the power tube 301 .

[0036] The pulp-slag separation device after pulping in the papermaking process is described. When in use, the mixture of pulp and waste residue is poured into the feed pipe 307. Since the power pipe 301, the feed pipe 307 and the bottom of the vertical return pipe 4 are connected through the slag pipe 3 and the pulp pipe 1, the pulp-slag mixture will enter the power pipe 301 and the vertical return pipe 4 and maintain the level of the liquid level. When the pulp-slag mixture enters the pulp pipe 1, it will pass through the screen slot 203 on the screen plate 202. The screen slot 203 only allows pulp with a smaller volume to pass through, and the waste residue is blocked on the left side of the screen plate 202. The pulp passing through the screen slot 203 will push the movable plate 207 to move right on the slide bar 204. The elastic belt 211 stretches in this process to absorb elastic potential energy, and then the electric telescopic rod The piston 306 is alternately extended and shortened, driving the piston 306 to alternately rise and fall in the power tube 301. When the piston 306 rises, a negative pressure is formed in the power tube 301, and the liquid level of the pulp-slag mixture in the power tube 301 rises, and the liquid level of the pulp-slag mixture in the feed tube 307 drops. The pulp hydraulic pressure in the pulp tube 1 is stronger than the pressure at the bottom of the feed tube 307. The pulp in the pulp tube 1 has a tendency to flow back, and the left side of the movable plate 207 is no longer pushed by the pulp. The elastic band 211 pulls the movable plate 207 to the left on the slide bar 204, so that the plug 210 fixed on the movable plate 207 is inserted into the screen slot 203, and the pulp blocked in the screen slot 203 is pushed into the feed tube 307 to avoid blockage. When entering the horizontal return pipe 401 and passing through the canvas layer 402, the water in the pulp will enter the horizontal return pipe 401, and the pulp will be isolated in the vertical return pipe 4. Due to the drop of the liquid level in the feed pipe 307, the water in the horizontal return pipe 401 can re-enter the feed pipe 307 through the canvas layer 402 slag pipe 3. When the piston 306 descends, the liquid level of the pulp-slag mixture in the power pipe 301 drops, and the liquid level of the pulp-slag mixture in the feed pipe 307 rises to be higher than the liquid level of the pulp-slag mixture in the vertical return pipe 4. The one-way valve 403 only allows liquid to flow from the horizontal return pipe 401 into the feed pipe 307. At this time, the one-way valve 403 closes the left side of the horizontal return pipe 401, and the pulp-slag mixture at the bottom of the feed pipe 307 re-moves the movable plate 2 07 pushes the slide bar 204 to the right to pull the insert plate 210 out of the screen slot 203, and the pulp enters the pulp pipe 1 through the screen slot 203 and the leakage hole 209. In this way, the piston 306 rises and falls repeatedly, and the pulp-residue mixture can be continuously washed while keeping the screen slot 203 unblocked, so as to completely separate the pulp and waste residue. After that, the staff can open the second cover 303 and the first cover 102, and take out the separated waste residue and pulp through the residue discharge pipe 302 and the pulp discharge pipe 101 respectively. After the separation operation is completed, unscrew the hexagonal nut 106 on the threaded rod 105, and take out the sealing plate 2 and the screen plate 202 together with the movable plate 207 for cleaning. When separating pulp of different volumes, the screen slots 203 of different widths can also be replaced.

Although the present invention is specifically demonstrated and introduced in conjunction with the preferred embodiments, there are many methods and approaches to implement the technical solution.
