Description

Technical Field

[0001] The invention relates to the technical field of cell wall crushing and processing, in particular to a biological cell wall pre-treatment crushing and filtering system. Background Art

[0002] In biological applications, there are some cases where it is necessary to destroy the cell wall to release substances inside the cell or to perform further experimental operations. For example, the preparation of protoplasts: protoplasts refer to the liquid part of the cytoplasm after the cell membrane and cell wall are broken.

[0003] Studies have found that during the brewing process, waste yeast cells undergo a process of rupture and dissolution, releasing the cell contents into the liquid to form protoplasts. Further studies have found that during the brewing process, about 100 tons of waste yeast are produced for every 10,000 tons of beer produced. Since waste beer yeast is rich in various nutrients such as protein, ribonucleic acid, B vitamins, lipids, polysaccharides and enzymes, and has multiple physiological functions, it can be used to make feed. However, since yeast has a relatively solid cell wall, the substances in its cells are not easy to release, so it cannot be well absorbed and utilized by animals as feed. Therefore, before making waste beer yeast into feed, it is necessary to perform a pre-treatment process to break the cell wall of the waste beer yeast.

[0004] The researchers found that currently, common equipment uses a grinding and wall-breaking device to grind the yeast slurry of waste brewer yeast, and then performs filtrate treatment on the broken cell solution to eliminate residual substances. However, most grinding devices have a low crushing rate and poor crushing effect, and are unable to fully break up the cell walls of the yeast, resulting in the substances in the yeast not being fully released. Moreover, when pouring, the yeast slurry easily adheres to the barrel wall of the device and is difficult to pick out, resulting in waste. Summary of the invention

The specific connection methods of each part all adopt conventional means such as mature bolts, rivets, welding, and bonding in the prior art, which will not be described in detail here.

[0039] Embodiment 1:

[0040] like Figure 1-Figure 13 As shown, Embodiment 1 of the present invention provides a biological cell wall pre-treatment crushing and filtering system, including a flow guide frame 1, a support frame 2, an electric guide rail 31, an electric slider 32, a grinding and crushing mechanism, a liquid discharge mechanism and other mechanisms;

[0041] The two sides of the guide frame 1 are connected to the support frame 2 by bolts, the tops of the two support frames 2 are connected to the electric guide rails 31 by bolts, the two electric guide rails 31 are slidably connected to the electric sliders 32, a grinding and crushing mechanism is provided between the two electric sliders 32, and the liquid discharge mechanism is provided on the grinding and crushing mechanism. The guide frame 1 is provided with a liquid outlet.

[0042] The biological cell wall pre-treatment crushing and filtering system provided by the embodiment of the present invention adopts a semi-open structure design for its main structure. The semi-open structure design of the grinding half frame is conducive to the installation and maintenance of various mechanisms; at the same time, air circulation is increased to avoid the continued fermentation of the crushed cell mud caused by long-term closed stirring;

[0043] The grinding and crushing mechanism includes a support plate 41 (the support plate 41 and the electric guide rail 31 are mainly made of aluminum profiles), a motor 42, a threaded long rod frame 43, a grinding sheet 44, a first wall-breaking tooth 45 and a gear ring 46. The two electric sliders 32 are connected with a support plate 41 by bolts, and the motor 42 is connected to the upper part of the support plate 41 by bolts, that is, the main function of the support plate 41 is to support and fix the motor 42 (the motor 42 preferably uses a stepping motor structure, and the motor 42 needs to undergo special explosion-proof and moisture-proof treatment); the threaded long rod frame 43 is fixedly connected to the output shaft of the motor 42 (the two are coaxially arranged, for example, coaxial rotation connection is achieved through splines, etc.), the threaded long rod frame 43 is vertically arranged, and the lower part of the threaded long rod frame 43 is rotatably connected to two grinding sheets 44 (or grinding parts);

[0044] The outer edges of the two grinding sheets 44 are fixedly connected with first wall-breaking teeth 45 , and the gear ring 46 is connected to the lower part of the support plate 41 by bolts. The two first wall-breaking teeth 45 are both located in the gear ring 46 , and the two first wall-breaking teeth 45 are both meshed with the gear ring 46 .

[0045] The liquid discharge mechanism includes a bent pressure rod 51, a rack long rod 52, a return spring 53, a grinding half frame 54, a gear three 55, a torsion spring one 56 and a cell filter membrane 57;

[0046] The bent pressure rod 51 is slidably connected to the support plate 41, and the bent pressure rod 51 is threadedly connected to the threaded long rod frame 43. The lower parts of the two electric guide rails 31 are slidably connected with rack long rods 52. The bent pressure rod 51 is located above the two rack long rods 52. A reset spring 53 is connected between the rack long rod 52 and the electric guide rail 31. The two support frames 2 are rotatably connected with grinding half frames 54, and the two grinding half frames 54 are in contact; the two grinding half frames 54 are located above the guide frame 1, and the two grinding half frames 54 are connected with gear three 55 through flat keys. The rack long rod 52 is meshed with gear three 55. A torsion spring one 56 is connected between the grinding half frame 54 and the support frame 2, and the cell filter membrane 57 is fixedly connected in the guide frame 1.

[0047] Analysis of the main structure of the above biological cell wall pre-treatment crushing and filtration system shows that:

[0048] In actual operation, the staff first pours yeast slurry of waste beer yeast into the two grinding half frames 54 so that the yeast slurry just covers the inner bottom of the two grinding half frames 54, and then starts the electric guide rail 31, which drives the two electric slide blocks 32 to move downward, thereby driving the supporting plate 41, the motor 42, the threaded long rod frame 43 and other component structures to move downward together;

[0049] At the same time, during the downward movement of the threaded long rod frame 43, the threaded long rod frame 43 will drive the grinding sheet 44, the first wall-breaking teeth 45 and the gear ring 46 to move downward together. When the grinding sheet 44 moves downward to contact the inner side of the grinding half frame 54, the electric guide rail 31 is closed and the motor 42 is started. The rotation of the output shaft of the motor 42 (i.e., the stepping motor) will drive the threaded long rod frame 43 to rotate. The rotation of the threaded long rod frame 43 will drive the two grinding sheets 44 and the two first wall-breaking teeth 45 to rotate together. Under the stirring action of the two grinding sheets 44 themselves and the friction between the teeth of the grinding sheets 44 and the gear ring 46, the brewing yeast cells in the grinding half frame 54 will be crushed (therefore, this structural design has a dual function). The single stirring function is realized by the rotation of the grinding disc 44, and the double wall breaking refers to the inter-tooth friction wall breaking function between the grinding disc 44 and the gear ring 46, and the wall breaking function of the internal and external gear grinding disc 47 cooperating with the grinding disc 44), which breaks the cell walls of the yeast cells, releases the substances in the yeast cells, and dissolves them in the solution. The two first wall-breaking teeth 45 rotate along the gear ring 46 while rotating, and the rotation of the first wall-breaking teeth 45 drives the grinding disc 44 to rotate. The rotation of the two grinding discs 44 and the rotation with the gear ring 46 can fully grind the yeast cells, and then fully break the cell walls of the yeast cells, thereby achieving a better wall breaking effect.

[0050] However, in a further technical solution, in order to enhance the grinding and wall-breaking effect and wall-breaking efficiency of the above-mentioned grinding sheet, the above-mentioned grinding sheet actually adopts a composite wall-breaking structure design; the composite wall-breaking structure is a grinding sheet 44 installed at the upper position and an inner and outer tooth grinding sheet 47 installed at the lower position, thereby forming a multi-tooth wall-breaking structure; the structure of the inner and outer tooth grinding sheet is detailed in Example 2;

[0051] Subsequently, the threaded long rod frame 43 moves downward and drives the curved pressure rod 51 to move downward. When the threaded long rod frame 43 rotates, the curved pressure rod 51 continues to move downward. The curved pressure rod 51 continues to move downward and contacts with the rack long rod 52, and pushes the two rack long rods 52 to move downward. The reset spring 53 is compressed, and the rack long rod 52 moves downward to drive the gear three 55 to rotate. The rotation of the gear three 55 drives the grinding half frame 54 to swing downward. The torsion spring one 56 is twisted, and the two grinding half frames 54 swing downward to pour the ground yeast mud into the guide frame 1. The cell filter membrane 57 filters the yeast cell solution, filters out the remaining residue of the yeast cell solution, and clarifies the filtrate. The filtered filtrate is discharged from the liquid outlet of the guide frame 1.

[0052] The staff then adjusts the output shaft of the motor 42 to rotate in the opposite direction, so that the threaded long rod frame 43 rotates in the opposite direction and drives the curved pressure rod 51 to move upward. The upward movement of the curved pressure rod 51 will disengage from the rack long rod 52, and the reset spring 53 will reset and drive the rack long rod 52 to move upward. The upward movement of the rack long rod 52 will drive the gear three 55 to rotate in the opposite direction. The reverse rotation of the gear three 55 will drive the grinding half frame 54 to swing upward, and the torsion spring one 56 will reset. Then the staff turns off the motor 42 and starts the electric guide rail 31. The electric guide rail 31 will drive the two electric sliders 32 to reset upward, thereby driving the support plate 41, the motor 42 and the threaded long rod frame 43 to reset upward together. The upward reset of the threaded long rod frame 43 will drive the grinding plate 44 and the inner and outer tooth grinding plates 47, the first wall-breaking teeth 45, the gear ring 46 and the curved pressure rod 51 to reset upward together.

[0053] Embodiment 2:

[0054] On the basis of Example 1, Figure 3-Figure 7 As shown, Embodiment 2 of the present invention provides a biological cell wall pre-treatment crushing and filtering system, including a flow guide frame 1, a support frame 2, an electric guide rail 31, an electric slider 32, a grinding and crushing mechanism, a liquid discharge mechanism and other mechanisms;

[0055] At the same time, it also has the same other structural designs as embodiment 1. Unlike embodiment 1, embodiment 2 also has a unique structural design;

[0056] That is, the grinding and crushing mechanism further includes an internal and external gear grinding disc 47; the internal and external gear grinding disc 47 is arranged below the grinding disc 44, because the grinding disc 44 is connected to the bottom of the threaded long rod frame through a rotating shaft 48 (the rotating shaft 48 in the embodiment of the present invention is actually a rotatable sleeve structure); the internal and external gear grinding disc 47 is installed on the inner wall of the rotating shaft through the above-mentioned smooth bearing, and the internal and external gear grinding disc 47 and the grinding disc 44 realize coaxial rotation (however, the "coaxial but different speed" rotation mode in the embodiment of the present invention means that the above-mentioned grinding and crushing mechanism adopts the "coaxial but different speed" wall breaking design concept for the first time);

[0057] In Embodiment 2 of the present invention, the internal and external tooth grinding disc 47 in the grinding and crushing mechanism has at least two significant design structural features and technical advantages.

[0058] The first aspect: although the internal and external toothed grinding disc 47 is a wall-breaking disc, it has the structure of internal and external wall-breaking blade teeth, that is, the edge of the internal and external toothed grinding disc 47 is provided with a plurality of inclined tooth pieces, and each tooth piece is sharpened to form a blade tooth structure (i.e., forming the second wall-breaking teeth 471); at the same time, an inner through hole is also provided at the center, and a circle of inclined tooth pieces (also multiple, i.e., forming the third wall-breaking teeth 472) is provided on the edge of the inner wall of the inner through hole, and each tooth piece is also sharpened to form a blade tooth structure; the use of blade tooth structures both inside and outside can significantly improve the wall-breaking effect of the internal and external toothed grinding disc 47;

[0059] The second aspect: the internal and external gear grinding disc 47 and the grinding disc 44 realize coaxial rotation, but the two may rotate relative to each other at "coaxial but different speeds", that is, "coaxial but different speeds". However, it should be noted that the "coaxial" mentioned here does not strictly mean using the same rotating shaft, but coaxial rotation. The specific scheme is as follows:

[0060] In the specific structural design, a bearing step 473 is provided above the surface between the inner through hole and the outer edge of the internal and external gear grinding disc 47; the bearing step is installed on the inner wall of the rotating shaft 48 through a smooth bearing (i.e., a deep groove ball bearing), that is, a bearing step is provided below the internal and external gear grinding disc 47, and the bearing step is installed on the inner wall of the rotating shaft 48 through a smooth bearing (the outer wall of the above-mentioned bearing step 473 and the inner ring of the smooth bearing are interference fit to achieve a tight installation, and a small hammer can be used to knock the assembly during the installation process), but the relative rotation of the rotating shaft does not drive the internal and external gear grinding discs. The grinding disc 47 rotates synchronously; because the internal and external gear grinding disc 47 is driven by a separate motor (i.e., the grinding disc drive motor) to realize rotation, different speed outputs of the two can be achieved as long as the output speed of the grinding disc drive motor is kept different from the rotation of the grinding disc 44; the grinding disc drive motor is fixedly installed at the top position of the inner cavity of the rotating shaft 48, that is, the inner wall cavity design of the rotating shaft 48 is actually (i.e., the rotating shaft 48 is a sleeve structure), and a separate drive motor, i.e., the grinding disc drive motor, is hidden and fixedly connected at the top of the inner wall cavity of the rotating shaft 48;

[0061] At the same time, the output shaft of the grinding disc driving motor extends outwardly through the rotating shaft 48 and continues to extend downward to be key-connected with the inner and outer gear grinding disc 47 at the bottom; therefore, strictly speaking, the motor output shaft of the grinding disc driving motor driven by the inner and outer gear grinding disc 47 and the rotating shaft 48 driven by the grinding disc 44 are not really one axis (one rotating axis), but are coaxial (coaxial), thereby forming a so-called "coaxial but different speed" grinding structure;

[0062] Generally speaking, there is no specific speed design. The speeds of the rotating shaft and the motor output shaft of the grinding disc driving motor are different most of the time. The reason for adopting the above-mentioned structural design is that it was found in the further research process that the "coaxial but different speed" grinding of the internal and external tooth grinding discs 47 and the grinding discs 44 further improves the wall breaking effect. Generally speaking, the grinding disc 44 located in the upper position has the function of stirring and wall breaking, so that the cell wall in the grinding half frame is broken as much as possible, and a stirring vortex with a larger diameter is formed from the top of the grinding half frame. However, if the internal and external tooth grinding discs 47 also adopt completely coaxial and same speed rotation, the cell wall breaking effect is not good. However, the output of the internal and external tooth grinding discs 47 with different speeds will cause the lower part of the grinding half frame to form vortex disorder or form a vortex with a smaller diameter. The two vortices rub against each other to enhance the fluidity of the yeast mud, and at the same time, the cell wall breaking effect is also enhanced.

[0063] Since the internal and external gear grinding disc is installed below the grinding disc, the moving distance will be limited when the threaded long rod frame moves downward to prevent the second wall-breaking teeth 471 of the internal and external gear grinding disc from crushing the half-frame mesh cloth and causing a conflict between the two.

[0064] Embodiment 3:

[0065] On the basis of Example 1, Figure 1-Figure 13 As shown, Embodiment 3 of the present invention provides a biological cell wall pre-treatment crushing and filtering system, further comprising a liquid guiding mechanism, the liquid guiding mechanism being arranged on a threaded long rod frame 43, the liquid guiding mechanism comprising a supporting right-angle rod 61, a rotating wheel 62, a collar 63 and a spiral plate 64;

[0066] The supporting right-angle rod 61 is connected to the bottom of the threaded long rod frame 43 by bolts. The supporting right-angle rod 61 is located between the two grinding plates 44. Both sides of the supporting right-angle rod 61 are rotatably connected to rotating wheels 62. Both sides of the supporting right-angle rod 61 are rotatably connected to rings 63. The rings 63 are fixedly connected to the rotating wheels 62. Spiral plates 64 are fixedly connected to the outer walls of the two rings 63.

[0067] Analysis of the specific structure of the above-mentioned liquid guiding mechanism shows that the above-mentioned threaded long rod frame 43 moves downward and drives the supporting right-angle rod 61 to move downward, and the supporting right-angle rod 61 moves downward and drives the rotating wheel 62, the collar 63 and the spiral plate 64 to move downward together, and the rotating wheel 62 and the spiral plate 64 move downward and contact the inner bottom of the grinding half frame 54, and the threaded long rod frame 43 rotates and drives the supporting right-angle rod 61 to rotate;

[0068] The rotation of the supporting right-angle rod 61 will drive the rotating wheel 62, the collar 63 and the spiral plate 64 to rotate together. The rotating wheel 62 will rotate along the inner bottom of the grinding half frame 54 while rotating. The rotation of the rotating wheel 62 will drive the collar 63 and the spiral plate 64 to rotate together. Since the rotation of the two grinding sheets 44 will squeeze the yeast cells to the middle of the two grinding half frames 54, the rotation of the two spiral plates 64 will guide the yeast cell solution in the middle of the two grinding half frames 54 to the surroundings, and then spread the yeast cells concentrated in the middle of the two grinding half frames 54, so that the two grinding sheets 44 can grind the yeast cells more fully when rotating, break the cell walls of the yeast cells more thoroughly, and release the substances in the yeast cells more fully, thereby effectively improving the cell wall breaking effect of the yeast cells.

[0069] At the same time, the upward resetting of the threaded long rod frame 43 will drive the supporting right-angle rod 61 to reset upward, and the upward resetting of the supporting right-angle rod 61 will drive the rotating wheel 62, the ring 63 and the spiral plate 64 to reset upward together, and the upward resetting of the rotating wheel 62 and the spiral plate 64 will disengage from the grinding half frame 54.
