Most of the pre-soaking devices in the prior art are spiral pre-soaking devices or scraper pre-soaking devices with curved sections.

[0049] In the following description of the utility model, the terms "upper", "lower", "front", "back", "left", "right", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the utility model and simplifying the description, and do not mean that the device must have a specific direction.

[0050] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below with reference to specific figures. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them.

[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0052] like Figures 1 to 10 As shown, the flat scraper inclined prepreg device of the utility model includes a flat shell 4, the top wall and the bottom wall of the flat shell 4 are parallel to each other and extend along a plane inclined to the ground, and the bottom of the flat shell 4 is supported on the ground by adjustable legs 19. The inclination angle of the flat shell 4 can be adjusted according to different materials. For white bean slices, the inclination angle of the flat shell 4 is usually 10-12°.

[0053] The upper end of the flat shell 4 is the head end, and the lower end is the tail end. The head end is equipped with a head shaft 7 along the width direction, and a pair of head shaft sprockets 7a are symmetrically installed on the head shaft 7; the tail end is equipped with a tail shaft 8 along the width direction, and a pair of tail shaft sprockets 8a are symmetrically installed on the tail shaft 8. A conveying chain 9 is wrapped between the head shaft sprocket 7a and the tail shaft sprocket 8a on the same side, and a partition is provided below the upper chain. The upper chain of the machine head is the machine head partition 4n, and the upper chain of the main body is the middle partition 4m. Multiple material pusher scrapers 10 are evenly fixed along the length direction of the conveying chain 9.

[0055] An upwardly erected prepreg feed port 4a is provided on the upper portion of the top wall of the flat shell 4. The prepreg feed port 4a extends along the full width direction and a solvent inlet 4b is connected to the side wall. An impeller feeder 3 is installed above the prepreg feed port 4a, and an upwardly extending storage box 1 is installed above the impeller feeder 3.

[0056] The material storage box 1 is in a trapezoidal shape with a narrow top and a wide bottom, and a new material inlet 1a is provided at the top center, and a material level sensor interface 1b is provided on one side of the new material inlet 1a for installing the material level sensor. A material distribution device 2 is provided below the new material inlet 1a, and a material distribution cone 1c is provided below the material distribution device 2. The material distribution cone 1c forms a hollow triangle at the upper center of the material storage box 1.

[0057] like Figure 4As shown, the material dividing plate 2a is erected upward, and the lower end of the material dividing plate 2a is fixed on the material dividing shaft 2b, and the material dividing shaft 2b extends along the length direction of the flat shell 4. One end of the material dividing shaft 2b is connected to an adjustment arm 2c perpendicular to the axis of the material dividing shaft 2b, and the free end of the adjustment arm 2c is connected to an adjustment arm pin shaft, and the adjustment arm pin shaft passes through the arc groove of the arc bracket 2e and is provided with a locking wrench 2d at the free end. The two ends of the arc bracket 2e are fixed to the shell of the storage box 1. The free end of the adjustment arm 2c can slide along the arc groove of the arc bracket 2e, driving the material dividing shaft 2b and the material dividing plate 2a to rotate, so that the materials entering the two channels of the storage box are basically uniform. After proper adjustment, the adjustment arm 2c and the material dividing plate 2a are fixed by the locking wrench 2d.

[0058] The material from the chute enters the upper end of the storage box 1 from the new material inlet 1a, and is evenly divided into the storage channels on both sides of the width direction by the dividing plate 2a and the dividing cone 1c, thereby increasing the material distribution capacity in the width direction. The width of the equipment can be more than 4 meters, and the material layer thickness along the width direction is relatively uniform.

[0059] like Figure 5 As shown, the impeller 3b of the impeller feeder 3 extends along the full width direction of the flat shell 4, the feeder shell 3a is adapted to the outer circle of the impeller 3b, and multiple shell reinforcement ribs 3c are provided along the outer wall of the feeder shell 3a in the length direction.

[0061] The material column of the storage box 1 plays the role of storing materials and isolating them. The feeding motor 3e drives the impeller 3b to rotate continuously, and the white bean slices are uniformly discharged downward. At the same time, a sufficiently uniform solvent enters from the solvent inlet 4b to mix with the materials, and then the white bean slices are evenly spread on the middle partition 4m. The explosion-proof motor 5 drives the head shaft 7 to rotate through the planetary reducer 6, and the head shaft sprocket 7a drives the tail shaft sprocket 8a to rotate through the conveying chain 9. The conveying chain 9 drives the material pusher 10 to move forward. The upper material pusher 10 pushes the white bean slices to move horizontally along the middle partition 4m to the tail end, and reaches below the soaking line to enter the solvent for soaking. After crossing the tail shaft sprocket 8a, the lower material pusher 10 pushes the soaked white bean slices to move upward along the bottom wall until the white bean slices are higher than the soaking line. The long gap between the adjacent grate bars 10a is used for the solvent to flow back in the draining area, and finally discharged from the discharge port 4d below the head end. By controlling the chain speed of the conveying chain 9, it is ensured that the material has sufficient residence time, so that the required pre-soaking effect is achieved before the material enters the extractor.

The overflow port 4e on the rear side is located above the upper chain, and the overflow port 4e in the middle section is located below the partition, which jointly control the height of the solvent immersion line to prevent the solvent from being carried out with the material.

[0063] A gas phase port 4c is provided on the top wall of the flat shell 4 at a position above the solvent soaking line. Usually, gas phase ports 4c are provided on both sides of the prepreg feed port 4a to discharge gas before operation or maintenance.

The chain flushing port 4h is symmetrically arranged in the width direction of the top wall. The chain flushing port 4h is connected to a fresh solvent pipe for cleaning the conveying chain 9 passing over the machine head.

[0068] like Fig. 9 , Fig.10 As shown, a sealing mounting seat 11 is fixed to the outer wall of the wall panel at the tail end, the tail shaft 8 passes through the sealing mounting seat 11, a bearing seat 12 is fixed to the outer wall of the sealing mounting seat 11, and an O-ring is used to seal the bottom of the bearing seat 12 and the outer wall of the sealing mounting seat 11. The inner wall of the bearing seat 12 near the root is provided with a bearing seat inner step, and two skeleton oil seals 13 are provided between the bearing seat inner step and the sealing mounting seat 11.
