Description

Technical Field

[0001] This utility model relates to the field of hydrophilic colloid production technology, and to a crushing device for wet fibers after alcohol precipitation. Background Technology

[0002] Currently, hydrophilic colloids (such as carrageenan and pectin) are commonly extracted in industrial production using alcohol precipitation, which involves using organic solvents such as ethanol and isopropanol to precipitate the colloids from aqueous solutions, forming wet fibrous alcohol precipitates (80-90% water content). This process is simple to operate and produces high purity, and is widely used in the food, pharmaceutical, and daily chemical industries. However, after extrusion, the alcohol precipitate forms hard, lumpy or clump-like precipitates (50-60% water content). Due to the residual alcohol-water mixture on the surface and its own hydrophilic properties, traditional crushing techniques easily cause these precipitates to adhere to the blades, screens, or inner walls of the crushing equipment. The wet fibers have a dense internal structure, making it difficult for traditional mechanical shearing forces to effectively separate the fiber bundles, often resulting in a phenomenon where the surface is broken but the interior remains in large pieces, affecting the uniformity of subsequent drying.

[0003] Traditional crushers with a single-row blade structure cannot achieve multi-dimensional shearing, resulting in large materials needing to be crushed multiple times; the energy utilization rate of material-blade collisions during high-speed rotation is low, generating excessive ineffective frictional heat; insufficient axial conveying power easily causes material accumulation and blockages; and unreasonable design of the distance between the blades and the housing leads to increased equipment vibration and shortened service life. Utility Model Content

[0004] This invention provides a crushing device for wet fibers after alcohol precipitation, in order to solve the problems of the prior art.

[0005] The objective of this utility model can be achieved through the following technical solution: a crushing device for wet fibers after alcohol precipitation, comprising a support frame, a crushing chamber disposed on the support frame, a crushing module disposed within the crushing chamber, and a driving mechanism disposed on the side of the crushing chamber. The crushing chamber has a feed inlet at its upper end and a discharge outlet at its lower end. The crushing module includes a rotating shaft rotatably disposed within the crushing chamber and blades fixedly disposed on the rotating shaft. The blades are arranged in three rows at equal intervals in a ring along the radial direction of the rotating shaft and form a preset angle with the axial direction of the rotating shaft, so that the blades, when rotating, have the function of crushing wet fibers and pushing the crushed fibers toward the discharge outlet. The output end of the driving mechanism is connected to the rotating shaft for driving the rotating shaft to rotate.

[0006] In a further improvement, the drive mechanism includes a drive motor, a drive wheel, a driven wheel, and a transmission component. The drive wheel is fixedly connected to the output shaft of the drive motor, the driven wheel is fixedly connected to one end of the rotating shaft, and the transmission component is wound around the drive wheel and the driven wheel.

[0007] As a further improvement, a protective shell is provided on the outside of the drive mechanism, and the protective shell is fixedly connected to the side wall of the crushing chamber.

[0008] In a further improvement, the pulverizing chamber is provided with a cleaning port, and the cleaning port is provided with a sealing cover. One side of the sealing cover is hinged to the pulverizing chamber by a hinge, and the other side is fastened to the pulverizing chamber by a buckle.

[0009] A further improvement is that a sealing gasket is provided between the edge of the sealing cap and the opening edge of the cleaning port.

[0010] In a further improvement, the two ends of the rotating shaft are rotatably connected to the crushing chamber via bearings, and a limiting ring is provided at both ends of the rotating shaft located on the blade. The limiting ring is fixed coaxially with the rotating shaft to restrict the axial movement of the rotating shaft.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. The blades of this utility model are arranged in three rows along the axis of rotation, forming coarse, medium and fine crushing zones to ensure that wet fibers are fully crushed and to prevent large pieces of material from falling before being crushed. The blades are designed with a 120° angle to the axis, which combines crushing and propulsion functions and reduces material residue in the crushing chamber. 2. The outer protective shell of the drive mechanism of this utility model isolates the high-speed transmission components, which not only prevents operators from accidentally touching and injuring themselves, but also prevents blocky wet fibers from falling into the transmission components and causing blockage. 3. The cleaning port of the pulverizing chamber of this utility model is equipped with a sealing cover, with a hinge and buckle design, which makes it easy to open and clean the internal residue. The sealing gasket on the edge of the sealing cover can prevent the alcohol precipitate from the wet fibers from seeping out from the gap, thus avoiding pollution of the equipment and the environment.

[0016] The following is a description of the embodiments and appendices. Figures 1-3 The technical solution of this utility model will be further described below.

[0017] Example 1 A crushing device for wet fibers after alcohol precipitation includes a support 1, a crushing chamber 2 disposed on the support 1, a crushing module 3 disposed in the crushing chamber 2, and a drive mechanism 4 disposed on the side of the crushing chamber 2. The crushing chamber 2 has a feed inlet 21 at its upper end and a discharge outlet 22 at its lower end. The crushing module 3 includes a rotating shaft 31 rotatably disposed in the crushing chamber 2 and blades 32 fixedly disposed on the rotating shaft 31. Multiple sets of blades 32 are equidistantly arranged in a ring along the axial direction of the rotating shaft 31 and form a preset angle with the axial direction of the rotating shaft 31, so that the blades 32 have the function of crushing wet fibers and pushing the crushed fibers toward the discharge outlet when rotating. The output end of the drive mechanism 4 is connected to the rotating shaft 31 for driving the rotating shaft 31 to rotate.

[0018] like Figures 1-3 As shown, the blades 32 of this invention are distributed in an axial advancing manner, with three blades in each group. The angle between each group of blades 32 and the axial direction is 120°, and the interval between adjacent blades 32 is 50mm. In actual use, The blades are arranged in three rows along the axial direction of the rotating shaft 31, with an axial spacing of 50mm between adjacent rows of blades 32. This allows the crushing chamber to form coarse, medium, and fine crushing zones from top to bottom, ensuring thorough crushing at each stage and preventing excessively large materials from falling to the lower area, thus avoiding incomplete crushing. At the same time, each blade 32 is also at a preset angle of 120° to the axial direction of the rotating shaft 31 to prevent material residue during the advancement process.

[0019] As a further preferred embodiment, the drive mechanism 4 includes a drive motor 41, a drive wheel 42, a driven wheel 43, and a transmission component 44. The drive wheel 42 is fixedly connected to the output shaft of the drive motor 41, the driven wheel 43 is fixedly connected to one end of the rotating shaft 31, and the transmission component 44 is wound around the drive wheel 42 and the driven wheel 44.

[0020] As a further preferred embodiment, the drive mechanism 4 is provided with a protective shell 45 on its outer side, and the protective shell 45 is fixedly connected to the side wall of the crushing chamber 2.

[0021] Specifically, the protective shell 45 can isolate the high-speed rotating transmission components, preventing operators from accidentally touching and injuring themselves, while also preventing clumps of wet fibers from accidentally falling into the transmission components and causing blockages.

[0022] As a further preferred embodiment, the pulverizing chamber 2 is provided with a cleaning port, and the cleaning port is provided with a sealing cover 23. One side of the sealing cover 23 is hinged to the pulverizing chamber 2 by a hinge, and the other side is fastened and fixed to the pulverizing chamber 2 by a buckle.

[0023] Specifically, when it is necessary to clean the inside of the crushing chamber 2, simply flip the sealing cover 23 upwards, and use a brush or high-pressure water gun to reach into the cleaning port for easy equipment maintenance.

[0024] As a further preferred embodiment, a sealing gasket is provided between the edge of the sealing cap 23 and the opening edge of the cleaning port, and the sealing gasket is used to seal the gap and prevent the alcohol precipitate from the wet fiber from seeping out from the gap between the sealing cap and the cleaning port.

[0025] As a further preferred embodiment, the two ends of the rotating shaft 31 are rotatably connected to the crushing chamber 2 via bearings, and a limiting ring 51 is provided at both ends of the blade 32 on the rotating shaft 31. The limiting ring 51 is coaxially fixed with the rotating shaft 31 to restrict the axial movement of the rotating shaft 31.

[0026] Specifically, the axial movement of the rotating shaft 31 is restricted by the limiting ring 51 during operation to avoid uneven crushing and fiber conveying jams caused by blade spacing deviation.

[0027] In summary, the working principle of this utility model is as follows: First, start the drive mechanism 4, which drives the rotating shaft 31 in the crushing chamber 2 to rotate through the transmission component, and the blades 32 on the rotating shaft 31 rotate together. Secondly, the wet fibers after alcohol precipitation are fed into the feed port 21 at the top of the crushing chamber 2. After the wet fibers enter the crushing chamber 2, they are crushed by the high-speed rotating blades 32. At the same time, the angle design between the blades 32 and the axial direction pushes the crushed fibers to move towards the bottom of the crushing chamber 2. Secondly, the crushed wet fibers are discharged from the discharge port 22 at the lower end of the crushing chamber 2 under the pushing action of the blade 32, and are collected by downstream equipment for subsequent processes; Finally, after the crushing operation is completed, turn off the drive mechanism 4, wait for the rotating shaft 31 and the blade 32 to stop completely, unfasten the buckle of the sealing cover 23, turn the sealing cover 23 around the hinge, clean the wet fibers remaining in the crushing chamber 2, and then fasten the sealing cover 23 again after cleaning.

[0028] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
