Description

Technical Field

[0001] The utility model relates to the field of papermaking machinery, in particular to a novel high-efficiency extrusion tearing machine. Background Art

[0002] The main raw materials for paper are plant fibers, such as wood pulp, straw pulp, and cotton pulp. Wood pulp is the most commonly used raw material in modern paper production. The extrusion tearing machine is the primary equipment used in pulping lines in the papermaking industry. The screw shaft's diameter gradually increases along the discharge direction, decreasing the space between the screw shaft and the outer filter drum. During operation, material enters the feed inlet and is transported forward by the screw shaft. The screw shaft and the outer filter drum squeeze and tear the wood chips, removing moisture, air, and some water-soluble substances from the chips.

[0003] A search revealed that Chinese patent publication number CN214782882U discloses a spiral extrusion and tearing machine, comprising a base, a cover, a transmission mechanism, an extrusion and tearing mechanism, a feed port, a discharge port, a flushing water pipe, and a filter drum. The transmission mechanism is mounted slightly to the left of the top center of the base, the cover is connected to the right end of the transmission mechanism, the extrusion and tearing mechanism is mounted within the cover, the feed port is mounted on the left of the top of the cover, the discharge port is mounted on the right end of the cover, a flushing water pipe is mounted on the top of the cover to the right of the feed port, and a filter drum is mounted between the extrusion and tearing mechanism and the inner wall of the cover. The high-pressure spiral in this utility model is a detachable structure that can adjust the spiral compression ratio according to the customer's slurry. This not only extends the service life of the original integrated spiral shaft but also significantly reduces the customer's cost of use.

[0004] This technical solution can improve the squeezing and tearing effects of wood chips by adjusting the spiral compression ratio. However, in actual use, it is more complicated to increase the squeezing and tearing effects by replacing the high-pressure spiral. It is necessary to shut down the equipment, replace it, and then debug it, which is more troublesome to use. Therefore, a new type of high-efficiency squeezing and tearing machine is proposed to solve the above problems. Utility Model Content

The outer periphery of the variable diameter rotating shaft 6 passes through and is rotatably connected to the left side of the extrusion bin 2. The diameter of the variable diameter rotating shaft 6 gradually increases from left to right, and the inner diameter of the extrusion bin 2 remains unchanged, so that the internal space of the extrusion bin 2 becomes smaller as it goes to the right, and the wood chips will be squeezed inside the extrusion bin 2. The outer periphery of the variable diameter rotating shaft 6 is fixedly connected to a transmission auger 7, which can transmit the material from the left end of the extrusion bin 2 to the right end. The outer periphery of the variable diameter rotating shaft 6 is fixedly connected to a crushing part 23 for crushing the extruded tanned wood.

[0032] Reference Figure 2-Figure 3, the extrusion seat 10 is slidably connected to a connecting sliding block 11, and the extrusion seat 10 limits the connecting sliding block 11 to move left and right only along the inner wall of the extrusion seat 10.

The left side of the connecting sliding block 11 is fixedly connected to an extrusion plug 12, and the side of the extrusion plug 12 is set to an inclined surface. The extrusion plug 12 contacts the inner wall of the left end opening of the extrusion bin 2. When the extrusion plug 12 moves to the left, the outer wall of the side of the extrusion plug 12 will be tightened along the inclined surface with the inner wall of the side of the extrusion bin 2. The right side of the connecting sliding block 11 is elastically connected to an adjusting round block 14 through an extrusion spring 13. When the connecting sliding block 11 is not under force, the extrusion spring 13 will push the connecting sliding block 11 to the left.

[0033] Reference Figure 1 and Figure 4 A material receiving bin 19 is fixedly connected to the inner wall of the bottom end of the fixed base 1. The opening position of the top of the material receiving bin 19 is opposite to the position of the discharge port 9. The wood discharged from the discharge port 9 will fall directly into the inside of the material receiving bin 19. A filter screen 20 is fixedly connected to the inside of the material receiving bin 19. The filter screen 20 can leak the liquid in the wood. The filter screen 20 is set to be high on the left and low on the right to facilitate the discharge of wood. A slope block 21 is fixedly connected to the inner wall of the bottom end of the material receiving bin 19. The slope block 21 is high at the back and low at the front. The falling liquid will be discharged forward under the action of gravity. A drain outlet 22 is opened on the front of the material receiving bin 19. The inner wall of the bottom end of the drain outlet 22 is opposite to the lowest end of the slope block 21, so that the liquid can be discharged smoothly from the drain outlet 22.

[0034] Working principle: When you want to conveniently adjust the extrusion and crushing effect, turn the knob 16, the knob 16 drives the threaded column 15 to move to the left, the threaded column 15 drives the adjusting block 14 to move to the left, the adjusting block 14 squeezes the extrusion spring 13, so that the extrusion spring 13 generates elastic potential energy, and increases the force of the extrusion spring 13 pushing the connecting sliding block 11 to the left. At this time, put the wood into the feeding port 3, the feeding port 3 is transported to the right end of the extrusion bin 2 by the transmission auger 7, and is squeezed and tanned by the extrusion bin 2 and the variable diameter rotating shaft 6. Then, the wood fibers are crushed into wood fibers at the crushing member 23, and the wood fibers accumulate at the right end outlet of the squeezing bin 2, pushing the squeezing plug 12 to the right. When the wood fibers are continuously crushed and squeezed, and the density of the wood fibers accumulated at the right end outlet of the squeezing bin 2 increases, the wood fibers will be able to push the squeezing plug 12 to the right, so that the wood fibers can be discharged from the discharge port 9. As the force of the squeezing spring 13 continues to increase, the greater the force the wood fibers need to push the squeezing plug 12, the longer the squeezing and crushing time of the wood fibers inside the transmission auger 7 is, thereby improving the squeezing and crushing effect. When it is desired to conveniently separate the discharged wood fibers and the liquid, the wood fibers fall from the discharge port 9, fall into the inside of the receiving bin 19, and fall on the filter screen 20. The liquid passes through the filter screen 20 and falls on the slope block 21, and is discharged from the drain outlet 22 along the slope. The wood fibers are discharged along the slope of the filter screen 20, thereby conveniently separating the wood fibers from the liquid.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
