[0002] In the traditional pulp residue separation technology, the common equipment often adopts the bottom pulp grinding design, and the core grinding unit and the separation area are highly integrated. This design easily leads to the early mixing of the raw materials and the separation medium in the crushing process, so that the effective components need to migrate or penetrate through the dense impurity layer for a long distance, which not only increases the flow resistance, but also reduces the separation precision. In the traditional pulp grinding equipment, the grinding and separation spaces overlap, and the pulp residue mixing phenomenon is serious, which further reduces the pulp yield and the residue separation effect. Although part of the improved technology attempts to optimize the separation path, it fails to fundamentally realize the spatial decoupling of the grinding and separation processes, and it is difficult to break through the efficiency bottleneck.

DETAILED DESCRIPTION

[0026] The utility model will be further explained in detail in combination with the drawings and specific embodiments.

[0027] Embodiment one:

[0028] As Figure 1As shown, the bottom plate center sleeve of the grinding head shell 1 is rotatably provided with a first coupling 2, and a first horizontal support plate 11 of the first coupling 2 is located in the grinding head shell 1. An upper surface of the first horizontal support plate 11 is connected with a separation basket 3, and the separation basket 3 is limited on the first horizontal support plate 11 by a first pin 12. A filter screen 4 is arranged on an inner wall of the separation basket 3. A plurality of leakage holes 10 are formed in the circumferential side wall and the bottom plate of the separation basket 3. In other embodiments, the separation basket 3 can only retain a basic frame and retain a filtering and blocking function through the filter screen 4. In this embodiment, the diameter of the first horizontal support plate 11 is smaller than the bottom plate of the separation basket 3, and the leakage holes 10 in the bottom plate of the separation basket 3 are located outside the first horizontal support plate 11. In other embodiments, the diameter of the first horizontal support plate 11 is the same as that of the separation basket 3, and the first horizontal support plate 11 is provided with a hole that is aligned with the leakage hole 10.

[0029] A first vertical shaft 13 of the first horizontal support plate 11 is downwardly sleeved on a rotating shaft 14 of a motor, and the rotating shaft 14 is transitionally connected with the first vertical shaft 13. The first vertical shaft 13 of the first horizontal support plate 11 penetrates through a center hole of the separation basket 3 upwardly, and a second coupling 5 is sleeved on the first vertical shaft 13 inside the separation basket 3. A second vertical shaft 15 of the second coupling 5 is transitionally connected with the first vertical shaft 13. The rotating shaft 14, the first coupling 2 and the second coupling 5 are coaxially connected, and are threadedly connected on the rotating shaft 14 through a fixing bolt 16 along a common center hole of the first coupling 2 and the second coupling 5.

[0030] The second coupling 5 is coaxially and rotatably arranged in a separation space of the separation basket 3. A second horizontal support plate 17 of the second coupling 5 is axially away from the circumferential side wall and the bottom plate of the separation basket 3 through the second vertical shaft 15. An upper surface of the second horizontal support plate 17 is connected with a lower grinding wheel 6. The lower grinding wheel 6 is limited on the second horizontal support plate 17 by a second pin 18. Figure 2 As shown, the lower grinding wheel 6 is higher than the bottom of the separation basket 3, and leaves a space at the bottom of the separation basket 3. An inlet channel 7 is arranged at an upper center position of the grinding head shell 1. The inlet channel 7 extends downwardly from the top to the opening of the separation basket 3. An upper grinding wheel 8 is connected with the lower end of the inlet channel 7. The upper grinding wheel 8 is axially aligned with the lower grinding wheel 6. A flow collecting cover 9 is connected with the lower end of the inlet channel 7. The flow collecting cover 9 is spacedly sleeved on the periphery of the upper grinding wheel 8 and the lower grinding wheel 6, and is away from the circumferential side wall and the bottom plate of the separation basket 3.

[0031] A slag outlet 19 and a slurry outlet 20 are arranged on the side wall of the grinding head shell 1. The slag outlet 19 is located at the upper part of the side wall of the grinding head shell 1 for discharging bean dregs. The slurry outlet 20 is located at the lower part of the side wall of the grinding head shell 1 for discharging soybean milk.

[0032] The utility model discloses a work time, motor drive pivot 14 is driven separation basket 3 rotation through the No. 1 coupling 2, simultaneously through the No. 2 coupling 5 linkage lower grinding wheel 6 and upper grinding wheel 8 form shearing refining zone, soybean enters after from feed channel 7, is pulverized into slag slurry mixture under the shearing force of high speed rotation of upper and lower grinding wheels.

[0033] The raised lower grinding wheel, the upper grinding wheel and the collector together form a high-position refining unit, which is located in the middle and upper part of the separation basket and connects the feed channel and the lower part of the separation basket in the axial position. Compared with the traditional method of prepositioning the lower grinding wheel at the bottom of the separation basket, the slag slurry separation path is optimized. In the traditional technology, the lower grinding wheel is located at the bottom of the separation basket, and the slag slurry mixture after crushing needs to be separated at the bottom of the side wall of the separation basket. The slurry needs to penetrate from the bottom upwards or outward, and the path of the slurry to the slurry outlet at the bottom of the grinding head shell is long. During the separation process, the slag slurry may be accumulated or mixed, which may interfere with the separation of the slurry. Conversely, the mixed slag slurry also affects the centrifugal action of the dregs, and the dregs mixed with water need to overcome greater gravity to rise from the bottom to the high-position dregs outlet. This disadvantage is caused by the overlapping of the refining and separation spaces, which causes the slag slurry to mix and affect each other during the slag slurry separation process. Not only does this result in low slurry output efficiency, but also low slurry output rate. In the utility model, the soybeans are crushed under the rotating shearing force of the upper and lower grinding wheels to form a slag slurry mixture. The collector surrounds the lower grinding wheel and the upper grinding wheel externally. Since the collector has a lower opening, the slag slurry mixture can be guided to fall vertically along the axial direction into the space formed at the bottom of the separation basket after the raised grinding wheel. Under the action of gravity, the slurry in the slag slurry mixture penetrates the filter screen and further enters the lower cavity of the grinding head shell through the leakage hole. The dregs are trapped in the inner circle of the separation basket. The coarse dregs after preliminary water filtration continue to adhere to the inner wall of the separation basket under the centrifugal force, forming a "dregs layer" and spirally rising along the inner wall. During this process, the slag slurry mixing degree is low due to the preliminary filtration, and the spiral rising speed is significantly accelerated. The slag slurry separation process is decoupled to the greatest extent, thereby forming a slag slurry separation path decoupling innovative design in the separation basket, which includes medium-high position crushing, medium-low position slurry discharge and medium-high position dregs discharge.

[0034] In summary, the present embodiment raises the lower grinding wheel to the middle and upper part of the separation basket to form an independent high-position crushing area and a low-position separation area, achieving spatial decoupling of the slag slurry generation and separation process. Compared with the slag slurry mixing interference caused by the traditional bottom refining, the slurry output efficiency is greatly improved, and the water content of the dregs is greatly reduced.

[0035] Embodiment two:

[0036] As Figure 3As shown, unlike Embodiment 1, the second coupling 5 is fitted with a crushing rotor 21, which extends upward into the feed channel 7. A crushing stator 22 is fitted on the inner wall of the feed channel 7 corresponding to the position of the crushing rotor 21, and the crushing rotor 21 is simultaneously rotated within the crushing stator 22. In this embodiment, the motor drives the rotating shaft 14 to rotate the separation basket 3 via the first coupling 2, while simultaneously, the second coupling 5 links the lower grinding wheel 6 and the upper grinding wheel 8 to form a wall-breaking zone. After the soybeans enter through the feed channel 7, they are crushed into a slurry mixture under the shearing force of the high-speed rotation of the upper and lower grinding wheels, and the mixture is collected. Cover 9 guides the mixture tangentially into the inner ring of separation basket 3; under centrifugal force, the slurry penetrates the filter screen and sinks through the holes to the bottom of the grinding head shell 1, and is discharged from the slurry outlet 20. Meanwhile, the soybean residue forms a spiral-rising residue layer on the inner wall of separation basket 3 under centrifugal force. After dehydration, it is discharged through the high residue outlet 19, forming an axial three-in-one integrated function of cell wall breaking, grinding, and residue-slurry separation. By breaking the cell wall first and then grinding, the pressure impact during the grinding process is reduced, which reduces the damage to the soybean skin fiber structure and the crude fiber content of the slurry, thus improving the taste of soybean products. At the same time, combined with the effect of Example 1, the grinding efficiency is further improved.

[0037] Example 3:

[0038] like Figure 4 As shown, a pulper includes a pulp-sludge separation component for high-level pulping and low-level filtration, as described in Embodiment 1 or Embodiment 2. The bottom outer periphery of the separation basket 3 has an impeller 23 with blades evenly distributed circumferentially. The impeller 23 can be fitted with the bottom outer periphery of the separation basket 3 via an annular connecting plate, or it can be integrally formed on the bottom outer periphery of the separation basket 3. The purpose of the impeller 23 is that when the separation basket 3 rotates, the circumferential blades of the impeller 23 generate a combined effect of centrifugal force and axial thrust, propelling the slurry to diffuse rapidly radially along the bottom of the separation basket 3, facilitating rapid slurry discharge, improving discharge efficiency, and shortening the separation cycle. Simultaneously, the thrusting effect of the impeller 23 outside the separation basket 3 breaks the laminar flow of the slurry, reducing the risk of filter clogging caused by excessively high local concentrations. Therefore, it is particularly suitable for processing high-fiber raw materials.

[0039] In summary, the utility model relates to a kind of pulp residue separation assembly of high-position pulping low-position filtering and pulping machine, belong to food processing machinery technical field.Aiming at the problem such as residue pulp mixing, low separation efficiency caused by the space overlap of pulping and filtering in traditional pulp residue separation equipment, the scheme realizes space decoupling by structural innovation: the lower grinding wheel is lifted to the upper part of separation basket, and forms high-position pulping unit with upper grinding wheel and collecting cover, raw materials are vertically dropped into the bottom of separation basket after high-speed shearing and crushing, and pulp is quickly sunk to low-position pulp outlet and discharged by filter screen and leakage hole, and dregs are spirally raised along inner wall by centrifugal force and discharged by high-position dregs outlet.This design optimizes residue pulp separation path, reduces mutual interference, significantly improves pulp discharge efficiency and reduces dregs moisture content.Further by adding crushing rotor and stator (embodiment two), realize first wall breaking then pulping, reduce fiber damage and improve pulp quality;Separation basket bottom is equipped with impeller (embodiment three), accelerate pulp diffusion and reduce filter screen clogging risk, especially suitable for high-fiber raw materials.The scheme has the advantages of compact structure, stable transmission, energy saving and high efficiency, and is suitable for high-fiber food processing such as bean products, breaks through the efficiency bottleneck of traditional technology, and provides innovative solution for pulp residue separation field.
