[0042] The working principle of the material storage bin distributing device is as follows:

[0043] Material sealed storage and feeding control

[0044] 1. Sealed feeding mechanism: material is fed through the material guide hopper on the sealed cover 211, and the electric butterfly valve at the lower end of the material guide hopper can accurately control the feeding amount - when the material level meter detects that the material in the sealed bin 210 reaches the preset height, the electric butterfly valve automatically closes to prevent material overflow; the tight fit of the sealed cover 211 and the sealed bin 210 and the sealing structure of the electric butterfly valve can prevent the material from being damp, dusty or externally contaminated.

[0045] 2. Bin height adaptation: the support 240 of the outer wall of the sealed bin 210 adopts a "sleeve + support rod" lifting structure, which can adjust the height of the sealed bin 210 up and down along the support rod by loosening the inner hexagonal studs on the side wall of the sleeve, and adapt to different heights of downstream drying equipment; after adjustment, tighten the inner hexagonal studs to achieve rigid locking through the resistance of the studs to the surface of the support rod, ensuring the stability of the bin.

[0046] Two-way stirring material homogenization mechanism

[0047] 1. Stirring power transmission: the reversible motor 221 is fixed in the protective cover outside the sealed bin 210, and the gear 224 coaxially fixed with the driving shaft of the reversible motor 221 is engaged with the toothed disc 223 at the top of the sealed bin 210, driving the toothed disc 223 to rotate, and the ball between the bottom of the toothed disc 223 and the protrusions on the inner wall of the sealed bin 210 reduces the rotational friction; the stirring rod 222 is fixedly connected with the toothed disc 223 and rotates synchronously with the toothed disc 223 to stir the material in the sealed bin 210 in the circumferential direction, breaking the material agglomeration and initially achieving homogenization.

[0048] 2. Up-and-down circulation enhanced material homogenization: the upper end of the feeding auger 232 is fixed coaxially with the toothed disc 223 and rotates synchronously with the toothed disc 223. When the reversible motor 221 operates in the forward direction, the feeding auger 232 rotates in the forward direction, and the material at the bottom of the sealed bin 210 enters the inside of the material guide cylinder through the material guide channel 233 on the side wall of the material guide cylinder 231, and is discharged from the top of the material guide cylinder 231 under the push of the auger helical blade, and falls back to the upper part of the sealed bin 210 - in combination with the circumferential stirring of the stirring rod 222, forming a three-dimensional material homogenization mode of "circumferential stirring + up-and-down circulation", ensuring that the material in the bin is uniformly consistent in composition.

[0049] Lifting-adjusted material distribution control mechanism

[0050] 1. Material distribution mode switching: when material distribution is needed, the reversible motor 221 is switched to operate in the reverse direction, the feeding auger 232 rotates in the reverse direction, the material in the material guide cylinder 231 is discharged from the lower end of the material guide cylinder 231 under the push of the auger, and enters the downstream drying equipment; the shaft radial limiting block 234 is slidingly connected in the limiting groove of the guide pipe 213, which not only limits the radial rotation of the material guide cylinder 231, but also limits the sliding amount of the material guide cylinder 231 in the axial direction.

[0051] 2. The rate of distribution is adjusted: the upper end of the electric push rod 235 is fixed with the discharge hopper 212, and the lower end is connected with the shaft radial limiting block 234. Starting the electric push rod 235 can drive the guide cylinder 231 to slide up and down: when the guide cylinder 231 moves up, the exposed area of the guide channel 233 in the sealed warehouse 210 increases (the opening of the channel expands the contact range with the material), the amount of material entering the guide cylinder 231 per unit time increases, and the distribution rate increases; when the guide cylinder 231 moves down, the exposed area of the guide channel 233 decreases, the distribution rate decreases, and the accurate control of the distribution amount is realized.

[0052] Liquid accumulation filtering mechanism of discharge hopper

[0053] 1. The double-layer structure separates water: the discharge hopper 212 adopts a double-layer structure of "filtering hopper 2121 + guide hopper 2122". The upper surface of the filtering hopper 2121 is located in the sealed warehouse 210, and its filter screen structure can filter the free water in the material (such as accumulated water in damp material and liquid impurities carried by the material); the filtered water falls into the lower guide hopper 2122, gathers along the hopper wall to the bottom liquid discharge interface 214, is transported to the waste liquid collection device through the pipeline, and realizes solid-liquid separation.

[0054] 2. Anti-blocking design: the rotation of the stirring rod 222 can bring the material to slide slightly on the surface of the filtering hopper 2121, reducing the accumulation of material on the filter screen and ensuring stable filtering efficiency.

[0055] It should be noted that the electric butterfly valve, the forward and reverse motor 221, and the electric push rod 235 all support PLC remote control, and cooperate with the material level meter to realize the full-process automation of "automatic feeding-automatic material uniformization-automatic distribution-automatic liquid discharge". The specific model and specification of the forward and reverse motor 221 and the electric push rod 235 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method uses the existing technology in the art, so it will not be described in detail.

[0056] The power supply of the forward and reverse motor 221 and the electric push rod 235 and its principle are clear to those skilled in the art, and will not be described in detail here.

[0057] The above only describes the embodiments of the present application and does not limit the protection scope of the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application. It should be noted that similar reference numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.
