[0071] The present invention is further described with reference to the following examples.

[0072] Example 1.

[0073] like Figure 1-5 As shown, a fully automatic cow dung fiber extraction equipment includes a main separation box 1 and a fiber collecting mechanism. The interior of the main separation box 1 is equipped with a feeding ring groove 2, a scattering and falling mechanism, a preliminary separation mechanism and a spiral pressing mechanism from top to bottom. The feeding ring groove 2, the scattering and falling mechanism, the preliminary separation mechanism and the spiral pressing mechanism cooperate with each other. The spiral pressing mechanism passes through the side wall of the main separation box 1 and extends to the outside of the main separation box 1 and cooperates with the fiber collecting mechanism.

[0074] The present application is used for fiber extraction from cow dung. Before entering the main separation box 1, the cow dung needs to be mixed with water to form a mixture of cow dung and water, and then enter from the feed ring groove 2. The surface of the feed ring groove 2 is inclined downward from the outside to the center, and cooperates with the scattering and falling mechanism to facilitate the cow dung to be scattered into the scattering and falling mechanism, and then scatter and preliminarily separated, and cooperates with the spiral pressing mechanism to realize the solid-liquid separation of the cow dung, extract the cow dung fiber, and collect and organize it through the fiber collecting mechanism.

[0075] The fiber collecting mechanism includes a fiber collecting trough body 3, which cooperates with the discharge end of the spiral pressing mechanism. A discharge cleaning component 4 is installed between the top of the side wall of the fiber collecting trough body 3 away from the spiral pressing mechanism and the spiral pressing mechanism, and a hot air pipe 5 is fixedly installed on the fiber collecting mechanism.

[0076] The fiber collecting mechanism loads the cow dung fibers through the fiber collecting trough 3. The discharge end of the spiral pressing mechanism is directly above the fiber collecting trough 3. The cow dung coming out of the spiral pressing mechanism is cow dung fibers. The discharge port is scraped and cleaned by the discharge cleaning component 4 to prevent the cow dung fibers from being blocked at the discharge end. The hot air pipe 5 can further increase the temperature inside the fiber collecting trough 3 and reduce the moisture content of the cow dung fibers.

[0077] The scattering and falling mechanism includes a top cone positioning cylinder 6 fixedly installed inside the main separation box 1 through two support arms 10, a cone portion 7 is provided on the top of the top cone positioning cylinder 6, the cone portion 7 extends to the inside of the feed ring groove 2, and a feed ring opening 8 is provided between the feed ring groove 2 and the cone portion 7. A vibration motor 9 is fixedly installed inside the top cone positioning cylinder 6, and a transmission protection disc 11 is fixedly installed at the output end of the vibration motor 9. A positioning retaining ring 12 is installed on the transmission protection disc 11, and the positioning retaining ring 12 and the bottom of the top cone positioning barrel are movably plugged in.

[0078] The breaking and falling mechanism cooperates with the feeding ring groove 2 through the cone portion 7 of the top cone positioning barrel, so that the cow dung and water mixture falls from the edge of the top cone positioning cylinder 6.

[0079] An annular screen 13 is installed around the outer side of the transmission protection disc 11, and a positioning outer ring 14 is installed around the outer side of the annular screen 13. A movable annular groove 15 is provided on the inner wall of the main separation box 1. The positioning outer ring 14 and the movable annular groove 15 are movably matched. A reset spring 16 is connected between the bottom of the positioning outer ring 14 and the bottom of the movable annular groove 15.

[0080] The output of the vibration motor 9 drives the transmission protection disc 11 to vibrate, and the transmission protection disc 11 drives the positioning retaining ring 12 to vibrate, and can prevent the cow dung and water mixture from entering the interior of the top cone positioning cylinder 6. At the same time, the positioning retaining ring 12 also plays a guiding role. The annular screen 13 can perform preliminary filtering on the cow dung and water mixture that falls from the edge of the top cone positioning cylinder 6. The connection between the positioning outer ring 14 and the reset spring 16 is coordinated inside the movable ring groove 15, so that the vibration motor 9 can drive the entire annular screen 13 to vibrate, further improving the preliminary filtration efficiency of the cow dung and water mixture and reducing the clogging of the annular screen 13.

[0081] The preliminary separation mechanism includes an inclined ring platform 17, a blanking pipe 18 is fixedly installed in the center of the inclined ring platform 17, and the inclined ring platform 17 includes a preliminary liquid collecting tank 19. The inner bottom height of the preliminary liquid collecting tank 19 gradually decreases from the blanking pipe 18 to the edge. A preliminary drainage pipe 20 is installed on the side wall of the preliminary liquid collecting tank 19. The preliminary drainage pipe 20 extends to the outside of the main separation box 1. An inclined ring filter 21 is fixedly installed above the preliminary liquid collection tank 19. The surface height of the inclined ring filter 21 decreases from the edge to the center, and the center of the inclined ring filter 21 is connected to the top edge of the preliminary drainage pipe 20.

[0082] The preliminary separation mechanism performs preliminary filtration on the cow dung and water mixture through the inclined ring platform 17. First, the cow dung and water mixture is preliminarily filtered through the inclined ring filter 21. The cow dung sewage is directly filtered and falls into the interior of the preliminary liquid collection tank 19, and is discharged to the outside of the equipment through the preliminary drainage pipe 20. The cow dung solid fiber can slide into the interior of the blanking pipe 18 using the inclined surface of the inclined ring filter 21 for the next step of processing.

[0083] The screw pressing mechanism includes a screw pressing cylinder 22, which is fixedly mounted on the side wall of the main separation box 1. A driving shaft 23 is rotatably mounted inside the screw pressing cylinder 22, and an auger blade 24 is mounted on the driving shaft 23. A feed hopper 25 is fixedly mounted on the top of the screw pressing cylinder 22, and the feed hopper 25 is docked with the blanking pipe 18. A screw pressing motor 26 is also installed inside the main separation box 1, and the output end of the screw pressing motor 26 is transmission-connected to the driving shaft 23. A screw pressing filter 27 is installed at the bottom of the screw pressing cylinder 22, and a collecting trough 28 is fixedly mounted at the bottom of the spiral pressing filter 27. A liquid collecting box 29 is installed at the bottom of the main separation box 1, and the discharge port of the collecting trough 28 is movably connected to the liquid collecting box 29.

[0084] The screw pressing mechanism introduces the cow dung and water mixture that has been preliminarily filtered into the interior of the screw pressing cylinder 22 through the feed hopper 25, and the screw pressing motor 26 cooperates with the reducer to drive the drive shaft 23 and the auger blade 24 to rotate, so that the cow dung and water mixture continues to move toward the discharge end away from the screw pressing motor 26. The cow dung fiber filtered water inside the screw pressing cylinder 22 can be filtered through the spiral pressing filter 27 and flow into the liquid collection box through the collection tank 28 for collection.

[0085] The discharge cleaning assembly 4 includes a horizontal support column 30 fixedly mounted on the fiber collecting trough body 3, and an extrusion disk 31 is fixedly mounted on the other end of the horizontal support column 30. The driving shaft 23 is rotatably mounted on the other side of the extrusion disk 31, and a pressing area 32 is provided between the spiral pressing cylinder 22 and the extrusion disk 31.

[0086] The cow dung and water mixture in the spiral pressing cylinder 22 can be further squeezed by the cooperation of the auger and the squeezing disk 31 to achieve solid-liquid separation. The squeezing area 32 between the squeezing disk 31 and the spiral pressing cylinder 22 obtains cow dung fibers after squeezing and filtration, and falls directly from the squeezing area 32. The squeezing disk 31 is fixed on the fiber collecting trough 3 through the horizontal support column 30.

[0087] An equipment positioning plate 33 is fixedly mounted on the horizontal support column 30, a discharge cleaning motor 34 is fixedly mounted on the equipment positioning plate 33, a gear ring A 35 is fixedly mounted on the output end of the discharge cleaning motor 34, a gear ring B 36 is rotatably mounted on the horizontal support column 30, gear ring A 35 and gear ring B 36 are engaged with each other, a Z-shaped connecting rod 37 is fixedly mounted on the gear ring B 36, a cleaning rod 38 is mounted on the other end of the Z-shaped connecting rod 37, a plurality of cleaning teeth 39 are mounted on the cleaning rod 38, and the cleaning rod 38 and the cleaning teeth 39 extend to the interior of the pressing area 32.

[0088] The output of the discharge cleaning motor 34 installed on the equipment positioning plate 33 drives the ring gear A 35 and the ring gear B 36 to rotate, and then drives the Z-type connecting rod 37 to rotate. The cleaning rod 38 and the cleaning teeth 39 extend into the pressing area 32. The cleaning rod 38 and the cleaning teeth 39 are driven to rotate by the Z-type connecting rod 37, breaking up the cow dung fibers in the entire pressing area 32, so that the cow dung fibers can fall quickly into the interior of the fiber collecting trough 3, preventing the cow dung fiber discharge from being blocked.

[0089] An auxiliary limiting ring groove 40 is formed on the extrusion disk 31 , and an auxiliary limiting rod 41 is fixedly mounted on the Z-shaped connecting rod 37 . The auxiliary limiting rod 41 is slidably engaged with the auxiliary limiting ring groove 40 .

[0090] The cooperation between the auxiliary limiting ring groove 40 and the auxiliary limiting rod 41 on the extrusion plate 31 can limit the circumferential rotation of the Z-shaped connecting rod 37, making its rotation more stable.

[0091] A material turning main rod 42 is movably installed on the side wall of the fiber collecting trough body 3, and a transverse positioning rod 43 is fixedly installed on one end of the material turning main rod 42. Several material turning rods 44 are installed on the transverse positioning rod 43. The other end of the material turning main rod 42 is connected to a hydraulic device 45 outside the fiber collecting trough body 3.

[0092] The cow dung fibers that fall into the fiber collecting trough 3 can further reduce their moisture content. By outputting the externally connected hydraulic equipment 45, the main turning rod 42, the transverse positioning rod 43 and the turning rod 44 are driven to move in both directions repeatedly, which can turn the fallen cow dung fibers over, increase the area of ​​the cow dung fibers exposed to the outside, further reduce the moisture content of the cow dung fibers, and improve the quality of the cow dung fibers.

[0093] The hot air pipe 5 is installed on the top of the fiber collecting tank 3, and the hot air pipe 5 is connected to an external heat exchange device.

[0094] The turning of the cow dung fibers in conjunction with the hot air pipe 5 can more efficiently reduce the moisture content of the cow dung fibers.

[0095] The present invention uses a breaking and dropping mechanism to break up the cow dung raw material mixed with water, so that the cow dung raw material is loose, and vibration and filtering are performed to achieve preliminary solid-liquid separation. During the squeezing process of the spiral pressing mechanism, the discharge cleaning component 4 is used to surround the cow dung fibers with low moisture content at the discharge port to assist in discharging, so as to prevent the cow dung fibers from being stuck at the discharge port of the spiral pressing mechanism. The moisture content of the cow dung is further reduced by the cooperation of the turning component and the hot air pipe 5, and the cow dung fibers are extracted, thereby realizing fully automated cow dung fiber extraction, reducing blockage, and improving the extraction efficiency of the cow dung fibers.
