Description

Technical Field

[0001] This invention relates to the field of food processing technology, and in particular to a slurry separator for cooked pulp processing. Background Technology

[0002] The cooking process is one of the core steps in soy milk production. The key is to effectively separate the cooked soy pulp from the soy milk. Commonly used pulp separation equipment includes centrifugal screens, vibrating screens, and extrusion separators. Because the cooked pulp material is quite viscous, like a paste, many machines tend to pile it up in one place when feeding it, resulting in uneven distribution. As a result, some soybean residue is discharged before it has been fully squeezed, leaving a lot of pulp residue in the residue, which leads to a low pulp yield. Summary of the Invention

[0003] The purpose of this invention is to provide a slurry separator for cooked pulp processing, which improves the yield of cooked pulp material.

[0004] This invention provides a slurry separator for cooked pulp processing, comprising a frame, on which a conical roller is mounted. A spiral rib is fixedly arranged on the outer circumference of the conical roller, and an annular rib is provided at the larger end of the conical roller to prevent the outflow of soybean pulp. One end of the conical roller is connected to a first pulley, and the other end passes through a discharge shell and is rotatably connected to the frame. A woven mesh is wrapped around the outside of the conical roller, and the woven mesh is connected to the frame via a fixing component, which clamps and fixes the two side edges of the woven mesh. A guide shell is provided at the bottom of the woven mesh. A motor frame is provided on the frame, and a power mechanism for driving the conical roller to rotate is mounted on the motor frame. The power mechanism includes a motor and a belt drive assembly, and the power mechanism also has an adjustment structure for adjusting the belt tension. A support plate is also provided on the motor frame, and a pulp inlet funnel is fixed on the support plate, the pulp inlet funnel being located above the open end of the woven mesh.

[0005] Preferably, the fixing component includes an arc-shaped bracket, the bottom end of which is fixedly connected to the frame and located on one side of the large end of the conical roller; two inclined rods are fixed on the arc-shaped bracket, both of which are inclined along the taper direction of the conical roller and fixedly connected to the feed shell.

[0006] Preferably, each of the inclined rods has an outwardly inclined upright fixed at both ends, and a connecting rod is provided between adjacent uprights. A stop bar is provided on the back of the connecting rod, and a bolt for tightening the woven mesh is installed in the stop bar.

[0007] Preferably, the two sides of the woven mesh pass through the gap between the tapered roller and the inclined bar and extend upward into the gap between the connecting rod and the stop bar, and the end of the bolt abuts against the surface of the woven mesh.

[0008] Preferably, the power mechanism includes a sliding plate, a crossbar fixed to one side of the sliding plate, two crossbars being inserted into a motor frame, a threaded rod hinged to one side of the sliding plate relative to the crossbar, the threaded rod being threadedly connected to the motor frame; the motor is fixed to the upper surface of the sliding plate, and a second pulley is fixed to the output end of the motor, the second pulley being connected to the first pulley via a belt.

[0009] Preferably, the flow guide shell is inclined and detachably connected to the frame.

[0010] Preferably, the bottom of the feeding shell is provided with a soybean residue discharge port.

[0011] Preferably, the annular stirrup is located at the end face of the large end of the conical roller, and its height is higher than that of the spiral stirrup.

[0012] Preferably, the larger end of the conical roller is close to the first pulley, and the smaller end extends into the interior of the feed housing.

[0013] Preferably, the inclined rod is arranged parallel to the outer circular surface of the conical roller.

[0014] The slurry separator for cooked pulp process provided by this invention has the following beneficial effects: The outlet of the pulp inlet funnel is aligned with the opening of the woven mesh, and the funnel is positioned slightly higher than the woven mesh. The pulp can flow down naturally by its own weight, preventing pulp accumulation. At the same time, the woven mesh forms a conical space around the conical roller, allowing the pulp to spread naturally along the inclined surface of the roller after falling in, further reducing accumulation. As the conical roller rotates, the spiral ribs on its surface push the soybean residue from the smaller end. During this process, the soybean residue is gradually squeezed towards the inner wall of the woven mesh, and the pulp seeps out through the mesh holes after being squeezed. Because the conical roller becomes thinner towards the smaller end, the space becomes narrower, and the pressure on the soybean residue increases as it moves forward. Finally, the soybean residue coming out from the smaller end is compressed to be drier, reducing the amount of pulp residue in the residue and increasing the pulp yield. Attached Figure Description

[0021] In this embodiment, as Figure 1 and Figure 2 As shown, the slurry separator for cooked pulp process includes a frame 1, on which a conical roller 2 is mounted. Spiral ribs 3 are fixedly arranged on the outer surface of the conical roller 2, and annular ribs 4 are provided at the large end of the conical roller 2 to prevent the outflow of soybean pulp. One end of the conical roller 2 is connected to a first pulley 5, and the other end passes through a discharge shell 6 and is rotatably connected to the frame 1. A woven mesh 7 is wrapped around the outside of the conical roller 2. The woven mesh 7 is connected to the frame 1 via a fixing component 8, which clamps and fixes the two side edges of the woven mesh 7. A guide shell 9 is provided at the bottom of the woven mesh 7. A motor frame 10 is provided on the frame 1, and a power mechanism for driving the conical roller 2 to rotate is mounted on the motor frame 10. The power mechanism includes a motor 14 and a belt drive assembly, and also has an adjustment structure for adjusting the belt tension. A support plate 17 is also provided on the motor frame 10, and a pulp inlet funnel 18 is fixed on the support plate 17. The pulp inlet funnel 18 is located above the open end of the woven mesh 7. Specifically, the height of the annular hoop 4 is higher than that of the spiral hoop 3, which can prevent the soy milk from flowing out from the large end. The small end of the conical roller 2 extends into the inside of the feed shell 6, so that the soybean residue can smoothly enter the feed shell 6 and be discharged. The slurry funnel 18 is fixed on the support plate 17 and is located above the opening end of the mat-shaped mesh 7, so that the slurry falls into the working area between the conical roller 2 and the mat-shaped mesh 7. The motor 14 is equipped with a speed controller, allowing operators to adjust its speed according to actual filtration requirements. For example, when a finer slurry is needed or the fine residue content in the slurry is reduced, the speed of the motor 14 can be reduced, causing the conical roller 2 to rotate slowly and extending the residence time of the material in the mesh 7, thereby improving filtration accuracy. When the throughput is large or the fineness of the slurry is not critical, the speed can be appropriately increased to improve production efficiency. In addition, the woven mesh 7 can be flexibly replaced according to the actual filtration mesh count requirements. The operator can loosen the bolts 86 in the fixing assembly 8 to release the pressure on the edge of the woven mesh 7, and then pull the original woven mesh 7 out of the gap between the conical roller 2 and the inclined rod 82. Then, it can be replaced with a woven mesh 7 with a higher mesh count (smaller mesh) or a lower mesh count (larger mesh), and then tightened again with bolts 86.

[0022] In some embodiments, such as Figure 1 and Figure 3 As shown, the fixing component 8 includes an arc-shaped bracket 81. The bottom end of the arc-shaped bracket 81 is fixedly connected to the frame 1 and located on one side of the large end of the conical roller 2. Two inclined rods 82 are fixed on the arc-shaped bracket 81. Both inclined rods 82 are inclined along the taper direction of the conical roller 2 and are fixedly connected to the feed shell 6.

[0023] Specifically, the arc-shaped bracket 81 provides support for the two inclined rods 82. The inclined rods 82 are arranged along the taper direction of the tapered roller 2, so that the gap between the woven mesh 7 and the outer surface of the tapered roller 2 is uniform. The inclined rods 82 are fixedly connected to the feed shell 6, which enhances the stability of the fixing component 8. The design of both diagonal bars 82 being inclined along the taper direction of the tapered roller 2 makes the opening formed at the top of the woven mesh 7 also tapered; In some embodiments, such as Figure 3 As shown, each diagonal bar 82 has an outwardly inclined upright bar 83 fixed at both ends, and a connecting bar 84 is provided between adjacent upright bars 83. A stop bar 85 is provided on the back of the connecting bar 84, and a bolt 86 for pressing the mat-type mesh 7 is installed in the stop bar 85. Specifically, the outward tilt of the upright 83 allows the top of the woven mesh 7 to be supported in a certain space for the introduction of slurry. The stop rod 85 is parallel to the connecting rod 84, and the two ends of the stop rod 85 are welded to the connecting rod 84. The bolts 86 on the stop rod 85 are used to directly abut against the edge of the woven mesh 7 to prevent the woven mesh 7 from loosening or shifting during operation. In some embodiments, such as Figure 1 As shown, the two sides of the woven mesh 7 pass through the gap between the tapered roller 2 and the inclined bar 82 and extend upward into the gap between the connecting rod 84 and the stop bar 85, and the end of the bolt 86 abuts against the surface of the woven mesh 7. Specifically, the two sides of the woven mesh 7 are guided into the gap between the connecting rod 84 and the stop rod 85. The bolts 86 are tightened so that the ends of the bolts press against the surface of the woven mesh 7, thereby tensioning and fixing the woven mesh 7. There are multiple bolts 86, which are evenly distributed based on the stop rod 85. To further address the issue that the woven mesh 7, due to its relatively hard material, is difficult to tightly adhere to the outer surface of the conical roller 2, this embodiment also includes an auxiliary fixing and adjustment structure: fixed circular tubes arranged axially are fixed at both ends of the frame 1, and the fixed circular tubes are mounted above both ends of the frame 1 via brackets; three stainless steel pull wires are fixed at three different positions on the outer side of the woven mesh 7, and each pull wire extends downward after passing around the corresponding fixed circular tube, and is stretched and adjusted by a tensioner installed on the outer side of the frame 1; By adjusting the tension of the tensioner, the circumferential tension of the woven mesh 7 and its coverage and fit with the conical roller 2 can be changed, ensuring that the woven mesh 7 forms a uniform and stable conical filtration space on the surface of the conical roller 2, and avoiding a decrease in filtration effect due to mesh loosening or offset.

[0024] In some embodiments, such as Figure 2 As shown, the power mechanism includes a sliding plate 11, a crossbar 12 fixed on one side of the sliding plate 11, two crossbars 12 being inserted into the motor frame 10, a threaded rod 13 hinged to one side of the sliding plate 11 relative to the crossbar 12, and the threaded rod 13 being threadedly connected to the motor frame 10; a motor 14 is fixed on the upper surface of the sliding plate 11, a second pulley 15 is fixed to the output end of the motor 14, and the second pulley 15 is connected to the first pulley 5 through a belt 16; Specifically, the sliding plate 11 is connected to the motor frame 10 via the crossbar 12 and can slide along the motor frame 10; (two crossbars are designed) the threaded rod 13 passes through a part of the motor frame 10 and is hinged to the sliding plate 11; when the threaded rod 13 is rotated, the sliding plate 11 and the motor 14 can be moved, thereby adjusting the center distance between the second pulley 15 and the first pulley 5, and adjusting the tension of the belt 16.

[0025] In some embodiments, such as Figure 1 and Figure 4 As shown, the flow guide shell 9 is tilted and detachably connected to the frame 1.

[0026] Specifically, the guide shell 9 is inclined so that the collected slurry can automatically flow to the lower end under the action of gravity, which facilitates the discharge of the slurry; the guide shell 9 is detachably connected to the frame 1, which facilitates disassembly, cleaning and maintenance. In addition, a slurry outlet is provided at the bottom of the guide shell 9, which can be used to directly place a container to collect the slurry.

[0027] In some embodiments, such as Figure 5 As shown, the bottom of the feeding shell 6 is provided with a soybean residue discharge port; Specifically, the feeding shell 6 is wrapped around the small end of the conical roller 2. The soybean residue enters the feeding shell 6 under the push of the spiral ribs 3. The downward tilt of the soybean residue outlet makes it easy for the soybean residue to be discharged from the soybean residue outlet by gravity.

[0028] In some embodiments, such as Figure 2 As shown, the annular stirrup 4 is located at the end face of the large end of the conical roller 2, and its height is higher than that of the spiral stirrup 3. Specifically, the tapered roller 2 has an annular rib at its large end, which is higher than the spiral rib. This design effectively prevents the soy milk from flowing out of the large end, allowing the soy milk to seep out only through the mat-shaped mesh 7.

[0029] In some embodiments, such as Figure 2 As shown, the large end of the conical roller 2 is close to the first pulley 5, and the small end extends into the interior of the feed housing 6; Specifically, the first pulley 5 is installed at the large end of the conical roller 2, which facilitates power input; the small end of the conical roller 2 extends into the inside of the feed shell 6, which facilitates the soybean residue to enter the feed shell 6 and be discharged smoothly.

[0030] In some embodiments, such as Figure 1 As shown, the inclined bar 82 is arranged parallel to the outer circular surface of the conical roller 2; Specifically, the inclined bar 82 is parallel to the outer circular surface of the conical roller 2, so that the gap between the woven mesh 7 and the conical roller 2 is uniform along the axial direction, which is beneficial for the material to be subjected to uniform extrusion and propulsion during the separation process.

[0031] The working principle of this application is illustrated below with a preferred embodiment: First, start the motor 14. The motor 14 drives the second pulley 15 to rotate. The second pulley 15 drives the first pulley 5 and the conical roller 2 to rotate through the belt 16. Since the large end of the conical roller 2 is connected to the first pulley 5 and the small end extends into the material feeding shell 6, when the cooked pulp mixture to be separated is evenly fed into the opening end of the mat-shaped mesh 7 through the pulp feeding funnel 18, the cooked pulp mixture falls into the space between the conical roller 2 and the mat-shaped mesh 7. Through the spiral ribs 3 fixed on the surface of the conical roller 2, the spiral ribs 3 exert a force on the material to push it towards the small end during the rotation of the conical roller 2, thereby achieving the extrusion and conveying of the soybean residue. During the rotation of the conical roller 2, the soy milk slurry flows out through the woven mesh 7 under the action of centrifugal force and gravity, and falls into the bottom guide shell 9. A container is placed at the discharge end of the guide shell 9 to collect the slurry; while the soybean residue is pushed by the spiral ribs 3 to the small end of the conical roller 2, enters the discharge shell 6, and is finally discharged from the soybean residue outlet at the bottom of the discharge shell 6. During installation, the two sides of the woven mesh 7 are clamped and fixed by the fixing components 8, and the bolts 86 are pressed against the mesh surface to keep the mesh surface taut and stable. The bottom of the woven mesh 7 wraps around the bottom of the conical roller 2. When it is necessary to adjust the tension of belt 16, since motor 14 is mounted on sliding plate 11, it is only necessary to rotate threaded rod 13. Threaded rod 13 drives sliding plate 11 to move laterally away from first pulley 5, and thus the tension of belt 16 can be adjusted by threaded rod 13.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
