Description

Technical Field

[0001] This application relates to the field of wolfberry processing technology, specifically to a high-speed processing equipment and filtration device for wolfberry pulp. Background Technology

[0002] The processing of goji berry pulp involves washing, feeding, crushing, and pulping. After crushing, the goji berries need to be filtered to retain the residue, which is then discharged. For example, Chinese patent CN217854973U discloses a goji berry pulp filtration device, which includes a pulp collection tank. A filter cylinder is fixedly connected to the top of the pulp collection tank. A shaft is rotatably connected to the inner bottom surface of the filter cylinder. A propeller blade is fixed to the outer wall of the shaft inside the filter cylinder. The propeller blade has a through-hole. A liquid outlet hole is opened through the outer wall of the bottom end of the filter cylinder. A liquid inlet is provided at the top of the filter cylinder. Multiple liquid inlet pipes, each connected to and inserted into the filter cylinder, are evenly connected and fixed to the bottom surface of the liquid inlet. A connecting pipe is fixedly connected to the top of the liquid inlet. A driving mechanism is provided between the connecting pipe and the filter cylinder. An inlet pipe is fixedly connected to the top of the connecting pipe. An impurity collection box is embedded and fixed at the bottom of the open end of the filter cylinder. This patent utilizes rotating paddles to simultaneously filter and remove slag. The filtered slurry flows downwards into a collection tank, while the filter residue is conveyed to an impurity collection tank by the rotating paddles. However, the slurry to be filtered in this device is prone to clogging in structures such as the infusion nozzle, infusion pipe, and connecting pipe. This is especially true for slurry made from crushed goji berries, which has a certain viscosity and is more prone to clogging. Therefore, its practicality is insufficient and it is not suitable for industrial processing. Analysis of existing solutions and related technologies reveals the following problems in the raw slurry processing: firstly, insufficient slurry filtration and slow filtration efficiency; secondly, slow overall processing speed; and thirdly, the filter residue carries a large amount of slurry, resulting in a low slurry yield.

[0003] In view of this, the present invention provides a high-speed processing equipment and filtration device for wolfberry pulp to optimize the deficiencies in the aforementioned prior art. Summary of the Invention

[0004] This utility model provides a high-speed processing equipment and filtration device for wolfberry pulp. By optimizing the feeding mechanism and the filtration and slag removal mechanism, it solves the technical problems of low processing rate of existing wolfberry pulp, insufficient pulp filtration, and low pulp yield.

[0005] In a first aspect, this utility model provides a high-speed processing device for wolfberry pulp, including a feeding hopper, a crushing mechanism, a filtration chamber, a pulp collection box, and a filter residue collection box. The feeding hopper is connected to the crushing mechanism, the filtration chamber is located at the upper end of the crushing mechanism, and the pulp collection box and the filter residue collection box are connected to the outlet pipe and the slag removal pipe of the filtration chamber. The feeding hopper is equipped with a stirring mechanism with a central axis, and the crushing mechanism includes a pair of crushing rollers. The filtration chamber includes a filtration section and a pressing section. The filtration section has a variable diameter and is equipped with perforated spiral blades for filtering the pulp. The pressing section is a cylindrical structure of equal diameter and is equipped with a propeller with variable-pitch blades inside. The rotation center of the perforated spiral blades and the rotation center of the propeller are set at a preset angle to each other. The outlet pipe is located at the preset angle, and the slag removal pipe is located at the end of the propeller.

[0006] Optionally, the stirring mechanism includes a central shaft and an angular stirring arm welded to the central shaft.

[0007] Optionally, a spiral feeding plate is provided on the central shaft, and the feeding plate is an arc-shaped plate.

[0008] Optionally, the gap between the edge of the perforated helical blade and the inner wall of the outer shell is larger as it gets closer to the pressing section.

[0009] Optionally, a groove is provided at the junction of the filtration section and the pressing section, and the liquid outlet pipe is screwed to the bottom end of the groove.

[0010] Optionally, the closer the blades on the propeller are to the adjacent layer of blades in the slag removal pipe, the smaller the spacing between them.

[0011] Optionally, in a set of crushing rollers, two of the crushing rollers may be equipped with different drive motors, or only one of the crushing rollers may be equipped with a drive motor.

[0012] Optionally, the outlet of the liquid outlet pipe is detachably connected to a filter assembly, the filter assembly including a housing, the housing having a C-shaped groove, the C-shaped groove being used for inserting the filter into the housing.

[0013] Secondly, this utility model provides a filtration device for filtering a mixture of pulp residue after crushing.

[0014] The principle and beneficial effects of this utility model are as follows:

[0015] In the high-speed processing equipment for wolfberry pulp provided by this utility model, wolfberries are poured into a feeding hopper and then crushed by paired crushing rollers in a crushing mechanism. The crushed pulp residue mixture enters a filtration chamber, which filters the pulp into a pulp collection box and discharges the wolfberry residue into a filter residue collection box. The structure of the filtration chamber achieves the following: First, the stirring mechanism in the feeding hopper increases the feeding rate while preventing material jamming; second, the variable diameter setting of the filtration section creates gradual compression, increasing the pressure on the material by reducing the chamber size, which helps to improve the filtration rate of the pulp. Furthermore, this variable diameter design increases the filtration area, allowing for faster and more complete pulp separation; third, the filter residue is squeezed and discharged, ensuring that the pulp in the filter residue is fully screened out, increasing the pulp yield. In addition, the filtration device provided by this utility model improves the filtration speed and filtration quality of wolfberry pulp. Attached Figure Description

[0020] The technical solutions in the embodiments of the application will now be clearly and completely described with reference to the accompanying drawings. Furthermore, the phrases "in one embodiment" or "in one embodiment" appearing throughout this specification do not necessarily refer to the same embodiment. Moreover, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0021] The processing of wolfberry pulp involves processes such as washing, feeding, crushing, and pulping. The existing pulp processing equipment has the following problems: First, the pulp filtration is insufficient and the filtration efficiency is slow; second, the overall processing rate is slow; and third, the filter residue carries a lot of pulp, resulting in a low pulp yield.

[0022] In one aspect, this utility model provides a high-speed processing equipment and filtration device for wolfberry pulp. The high-speed processing equipment for wolfberry pulp includes a feeding hopper 1, a crushing mechanism, a filtration chamber 3, a pulp collection box 2, and a filter residue collection box 4. The feeding hopper 1 is connected to the crushing mechanism, the filtration chamber 3 is located at the upper end of the crushing mechanism, and the pulp collection box 2 and the filter residue collection box 4 are connected to the outlet pipe and the slag removal pipe of the filtration chamber 3. The feeding hopper 1 is equipped with a stirring mechanism 5 with the center as the axis, and the crushing mechanism includes a pair of crushing rollers. The filtration chamber 3 includes a filtration section 31 and a pressing section 32. The filtration section 31 is configured with a variable diameter and is equipped with perforated spiral blades 311 for filtering the pulp. The pressing section 32 is a cylindrical structure with a constant diameter and is equipped with a propeller 321 with variable pitch blades. The rotation center of the perforated spiral blades 311 and the rotation center of the propeller 321 are set at a preset angle to each other. The outlet pipe is located at the preset angle, and the slag removal pipe is located at the end of the propeller 321.

[0023] Reference Figure 1 and Figure 2 As shown, in use, the high-speed processing equipment provided by this utility model involves pouring goji berries into the feeding hopper 1, where they are then crushed by paired crushing rollers in the crushing mechanism. The crushed slurry and residue mixture enters the filtration chamber 3, which filters the slurry into the slurry collection box 2 and discharges the goji berry residue into the filter residue collection box 4. The structure of the filtration chamber 3 achieves the following: First, the stirring mechanism 5 in the feeding hopper 1 increases the feeding rate while preventing material jamming; second, the variable diameter setting of the filtration section 31 creates progressive compression, increasing the pressure on the material by reducing the chamber size, which helps to improve the filtration rate of the slurry. Furthermore, this variable diameter design increases the filtration area, allowing for faster and more complete slurry extraction; third, the filter residue is squeezed out, ensuring that the slurry in the residue is fully screened out, thus increasing the slurry yield. It should be noted that the "preset angle" formed between the aforementioned filtration section 31 and pressing section 32 is an obtuse angle. One of the angles cannot be parallel to the horizontal plane, as this would cause backflow when there is excessive slurry. The angle between the filtration section 31 and the pressing section 32 and the horizontal plane is controlled to ensure that all the slurry flows towards the outlet pipe. However, the angle with the horizontal plane cannot be too large, as this would cause some goji berry residue to accumulate, affecting the slurry discharge efficiency. The specific angle can be adjusted according to the actual dimensions of the filtration section 31 and the pressing section 32.

[0024] Specifically, the stirring mechanism 5 includes a central shaft 51 and an angled stirring arm 52 welded to the central shaft 51. A spiral feeding plate, which is an arc-shaped plate, is mounted on the central shaft 51. Figure 3As shown, the motor driving the central shaft 51 controls its rotation, causing the angled stirring arm 52 welded to the central shaft 51 to rotate. This stirring arm can clear the goji berry material in the feeding hopper 1. Simultaneously, the feeding plate on the central shaft 51, during its rotation, can evenly distribute the goji berries to the discharge port of the feeding hopper 1, ensuring that the goji berries fall evenly into the stirring mechanism 5 below the discharge port, preventing blockage and affecting the overall processing speed. Furthermore, the curved plate, meaning its surface has a certain curvature, allows the stirred goji berry material to gather towards the central shaft 51, increasing the guiding effect of the discharge. Figure 3 The dashed lines in the diagram represent the shape of the feeding hopper 1, and are used to show the internal stirring mechanism 5. Additionally, the angular stirring arm 52 is a triangular stirring structure formed by welding or hinged one end of two circular tubes together, and then welding the other end of each tube to the central shaft 51.

[0025] Additionally, it should be noted that the gap between the edge of the perforated spiral blade 311 within the filter section 31 and the inner wall of the outer shell increases as it approaches the pressing section 32. A groove is provided at the junction of the filter section 31 and the pressing section 32, and the liquid outlet pipe is screwed to the bottom end of the groove. That is, in this embodiment, as the diameter of the perforated spiral blade 311 used for filtering slurry and conveying wolfberry residue gradually decreases along the axial direction, the gap between the blade and the inner wall of the outer shell gradually increases towards the pressing section 32. This increased gap facilitates slurry flow and helps prevent clogging at the small-diameter blade locations.

[0026] It should also be noted that the spacing between the blades of the propeller 321 in the aforementioned pressing section 32 and the adjacent blades of the slag removal pipe is smaller. The reduced spacing between adjacent blades near the slag removal pipe can compress the wolfberry residue, forcing the slurry in the residue to be fully released and flow into the liquid outlet pipe, thereby achieving thorough slurry filtration and increasing the yield of wolfberry slurry.

[0027] Additionally, it should be noted that this embodiment includes... Figure 1 The propeller 321 and the perforated helical blade 311 are not shown in the figure. According to common sense, the power for the rotation of this structure can be provided by an electric motor, or by combining gears to build a simple transmission mechanism, etc. This embodiment will not be described in detail.

[0028] In some embodiments, in the aforementioned crushing mechanism, a group of crushing rollers may have different drive motors installed on two of the crushing rollers simultaneously, or only one of the crushing rollers may have a drive motor. That is, in this embodiment, two different drive motors may be installed on the two crushing rollers simultaneously to drive the two crushing rollers to rotate in opposite directions, or only one drive motor may be installed on the crushing roller, and the active crushing roller may drive the opposing crushing roller to rotate by friction with the goji berries.

[0029] In other embodiments, a filter assembly is detachably connected to the outlet of the aforementioned liquid outlet pipe. The filter assembly includes a housing with a C-shaped groove for inserting the filter. In this embodiment, the filter assembly at the outlet of the liquid outlet pipe further filters any elusive goji berry residue from the slurry, thereby improving the filtration quality. To facilitate filter replacement and cleaning, the filter is inserted into the C-shaped groove on the housing for easy insertion and removal.

[0030] Secondly, this utility model also provides a filtration device for filtering the mixture of pulp residue after crushing. The filtration device includes the filtration chamber 3 in any of the aforementioned high-speed processing equipment for wolfberry pulp, and also includes a feeding conveying mechanism, a discharging conveying mechanism, and a liquid collection tank. The feeding conveying mechanism is connected to the inlet of the filtration chamber 3, the discharging conveying mechanism is connected to the slag outlet of the filtration chamber 3, and the liquid collection tank is connected to the liquid outlet of the filtration chamber 3.

[0031] In this embodiment, based on the aforementioned filter chamber 3, a feeding conveyor mechanism is provided to transport the wolfberry pulp and residue mixture into the filter chamber 3, a discharging conveyor mechanism is provided to transport the filtered wolfberry residue out, and a slurry collection tank is provided to collect the pulp, forming an automated filtration device with automatic feeding and discharging, thereby improving the filtration speed and filtration quality of the wolfberry pulp. Specifically, the feeding and discharging conveyor mechanisms can be implemented using belt conveyors.

[0032] Finally, this utility model provides a high-speed processing equipment and filtration device for wolfberry pulp. The processing equipment includes a feeding hopper 1, a crushing mechanism, a filtration chamber 3, a pulp collection box 2, and a filter residue collection box 4. The feeding hopper 1 is connected to the crushing mechanism, the filtration chamber 3 is located at the upper end of the crushing mechanism, and the pulp collection box 2 and the filter residue collection box 4 are connected to the outlet pipe and the slag removal pipe of the filtration chamber 3. The feeding hopper 1 is equipped with a stirring mechanism 5 with the center as the axis. The crushing mechanism includes a pair of crushing rollers. The filtration chamber 3 includes a filtration section 31 and a pressing section 32. The filtration section 31 is configured with a variable diameter and is equipped with perforated spiral blades 311 for filtering the pulp. The pressing section 32 is a cylindrical structure with a constant diameter and is equipped with a propeller 321 with variable pitch blades. The rotation center of the perforated spiral blades 311 and the rotation center of the propeller 321 are set at a preset angle to each other. The outlet pipe is located at the preset angle, and the slag removal pipe is located at the end of the propeller 321. This embodiment improves the processing rate of goji berry pulp by optimizing the feeding mechanism and the filtration and slag removal mechanism, and also achieves full filtration of the pulp, thereby increasing the yield of goji berry pulp.
