Description

Biological cell wall pretreatment crushing and filtering system

Technical Field

The invention relates to the technical field of cell wall crushing processing, in particular to a biological cell wall pretreatment crushing and filtering system.

Background

In biological applications, there are cases where it is necessary to destroy the cell wall in order to release the intracellular material or to perform further experimental procedures. For example: preparation of protoplasts: where protoplasts refer to the liquid fraction of the cytoplasm after rupture of the cytoplasmic membrane and cell wall.

It has been found that during brewing, spent yeast cells undergo a process of disruption and lysis, releasing the cell contents into the liquid to form protoplasts. Further studies have found that approximately 100t spent yeast is produced per 10000t of beer produced during beer brewing. The waste beer yeast contains rich protein, ribonucleic acid, vitamin B group, lipid, polysaccharide, enzyme and other nutritious components and has several physiological functions, so that it may be used in producing feed. However, since yeast has relatively firm cell walls, and substances in cells are not easily released, they cannot be well absorbed and utilized by animals as a feed, and therefore, a pretreatment process for disrupting the cell walls of spent beer yeast is required before the spent beer yeast is produced into a feed.

Researchers find that at present, common equipment can use grinding broken wall device to grind the yeast mud of beer waste yeast, then carry out filtrate treatment with broken cell solution to eliminate the residual material, but most grinding device breakage rate is lower, and the crushing effect is not good, can't fully break the cell wall of yeast, leads to the material in the yeast not fully released, and the yeast mud is very easy to adhere in the section of thick bamboo wall of device when empting moreover, is difficult for digging out, can cause the waste.

The main structure of the biological cell wall pretreatment crushing and filtering system is analyzed as follows:

In actual operation, the staff firstly pours the yeast slurry of the waste beer yeast into the two grinding half frames 54, so that the yeast slurry just covers the bottoms of the inner sides of the two grinding half frames 54, then starts the electric guide rail 31, and the electric guide rail 31 drives the two electric sliding blocks 32 to move downwards, so as to drive the supporting plate 41, the motor 42, the threaded long rod frame 43 and other component structures to move downwards together;

simultaneously, in the process of moving down the screw thread long rod frame 43, the screw thread long rod frame 43 can drive the grinding sheet 44, the first broken wall teeth 45 and the gear ring 46 to move down together, when the grinding sheet 44 moves down to be in contact with the inner side of the grinding half frame 54, the electric guide rail 31 is closed, and the motor 42 is started, an output shaft of the motor 42 (namely, a stepping motor) rotates to drive the screw thread long rod frame 43 to rotate, the screw thread long rod frame 43 rotates to drive the two grinding sheets 44 and the two first broken wall teeth 45 to rotate together, brewing yeast cells in the grinding half frame 54 can be crushed under the self-rotation stirring action of the two grinding sheets 44 and the inter-tooth friction action between the grinding sheets 44 and the gear ring 46 (therefore, the structural design has double wall breaking and double stirring functions, wherein the single stirring function is realized through the inter-tooth friction wall breaking function between the grinding sheets 44 and the gear ring 46, and the inner and outer broken wall breaking action of the inner and outer broken wall teeth 47 matched with the grinding sheets 44), the material in the yeast cell wall is crushed, the material in the yeast cell wall is released from the cell wall is fully crushed, and the first broken wall 45 rotates along the first broken wall 45 and the rotation effect of the gear ring 46, and the cell wall is fully ground, and the cell wall is fully rotated and the rotation and the cell wall is fully ground by the rotation of the first broken wall and the rotation wall and the gear wall is fully rotates.

However, in a further technical scheme, in order to enhance the wall breaking efficiency and the wall breaking efficiency of the grinding sheet, the grinding sheet actually adopts a structural design of a composite wall breaking mode; a composite wall-broken structure, namely an upper-mounted grinding sheet 44 and a lower-mounted inner and outer teeth-twisted grinding sheet 47, thereby forming a multi-tooth wall-broken structure; see example 2 for details regarding the structure of the inner and outer teeth wear plates;

Subsequently, the screw long rod frame 43 moves downwards and drives the bent compression rod 51 to move downwards, the screw long rod frame 43 rotates and drives the bent compression rod 51 to move downwards, the bent compression rod 51 moves downwards and contacts the rack long rods 52 to push the two rack long rods 52 to move downwards, the reset spring 53 is compressed, the rack long rods 52 move downwards and drive the three gears 55 to rotate, the three gears 55 rotate and drive the grinding half frame 54 to swing downwards, the torsion spring I56 is twisted, the two grinding half frames 54 swing downwards and pour the grinded yeast mud into the guide frame 1, the cell filter membrane 57 filters the yeast cell solution, residual residues of the yeast cell solution are filtered, filtrate is clarified, and the filtered filtrate is discharged from a liquid outlet of the guide frame 1.

Example 2:

On the basis of the embodiment 1, as shown in fig. 3-7, the embodiment 2 of the invention provides a biological cell wall pretreatment crushing and filtering system, which comprises a flow guiding frame 1, a supporting frame 2, an electric guide rail 31, an electric sliding block 32, a grinding and crushing mechanism, a liquid discharging mechanism and other mechanisms;

While also having other structural designs identical to those of embodiment 1, embodiment 2 also has a unique structural design, unlike embodiment 1;

I.e. the grinding and crushing mechanism further comprises inner and outer teeth grinding plates 47; the inner and outer teeth grinding sheets 47 are arranged below the grinding sheets 44, and the grinding sheets 44 are connected below the threaded long rod frame through the rotating shafts 48 (the rotating shafts 48 in the embodiment of the invention are actually rotatable sleeve structures); the inner and outer teeth grinding sheets 47 are mounted on the inner wall of the rotating shaft through the smooth bearing, and the inner and outer teeth grinding sheets 47 and the grinding sheets 44 realize coaxial rotation (but the rotation mode of "coaxial different speeds" in the embodiment of the invention means that the grinding and crushing mechanism adopts the "coaxial different speeds" wall breaking design concept for the first time);

In embodiment 2 of the present invention, there are at least two significant design structural features and technical advantages for the inner and outer teeth grinding sheets 47 in the grinding and crushing mechanism;

First aspect: the inner and outer teeth grinding disc 47 is a wall breaking disc, but the inner and outer teeth grinding disc 47 has an inner and outer wall breaking cutter tooth structure, that is, the edges of the inner and outer teeth grinding disc 47 are provided with a plurality of obliquely arranged tooth sheets, and each tooth sheet is edged to form a cutter tooth structure (that is, form a second wall breaking tooth 471); meanwhile, an inner through hole is arranged in the center of the inner wall of the inner through hole, a circle of obliquely arranged tooth sheets (a plurality of tooth sheets are also formed into a third broken wall tooth 472), and each tooth sheet is edged to form a cutter tooth structure; the wall breaking effect of the inner and outer tooth grinding sheets 47 can be obviously improved by adopting a cutter tooth structure inside and outside the machine;

Second aspect: the inner and outer teeth grinding sheets 47 and 44 realize coaxial rotation, but the two may generate relative rotation of 'coaxial different speeds', namely 'coaxial different speeds'; however, it should be noted that the "coaxial" is not strictly a same rotation axis, but a coaxial rotation, and the specific scheme is as follows:

In a specific structural design, a bearing step 473 is provided above the surface between the inner through hole and the outer edge of the inner and outer tooth wear plates 47; the bearing step is arranged on the inner wall of the rotating shaft 48 through a smooth bearing (namely a deep groove ball bearing), namely, the bearing step is arranged below the inner and outer tooth grinding disc 47 and is arranged on the inner wall of the rotating shaft 48 through the smooth bearing (the outer wall of the bearing step 473 is in interference fit with the inner ring of the smooth bearing to realize fastening installation, and small hammer striking assembly can be used in the installation process), but the relative rotation of the rotating shaft does not drive the inner and outer tooth grinding disc 47 to synchronously rotate; because the inner and outer teeth grinding sheets 47 are driven to rotate by separate motors (namely grinding sheet driving motors), different rotation speed outputs of the grinding sheet 44 can be realized as long as the output rotation speed of the grinding sheet driving motor is kept different from the rotation speed of the grinding sheet driving motor; the grinding disc driving motor is fixedly arranged at the top of the inner cavity of the rotating shaft 48, namely the rotating shaft 48 is actually designed into an inner wall cavity (namely the rotating shaft 48 is of a sleeve structure), and the top of the inner wall cavity of the rotating shaft 48 is fixedly connected with an independent driving motor in a hidden manner, namely the grinding disc driving motor;

Simultaneously, the output shaft of the grinding disc driving motor extends outwards and penetrates out of the rotating shaft 48 to extend downwards continuously to be connected with the inner tooth grinding disc 47 at the bottommost part in a key way; thus, strictly speaking, the motor output shaft of the abrasive sheet drive motor in which the inner and outer teeth abrasive sheets 47 are driven and the rotating shaft 48 in which the abrasive sheets 44 are driven are not exactly one shaft (one rotating shaft), but are in coaxial relationship (coaxial relationship), thereby forming a so-called "coaxial different-speed" abrasive structure;

generally, no special rotation speed design exists, the rotation speeds of the rotation shaft and the motor output shaft of the grinding disc driving motor are different for most of time, and the structural design is found in the further research process that because the inner and outer tooth grinding discs 47 and the grinding discs 44 rotate at different rotation speeds, the wall breaking effect is further improved, generally, the grinding discs 44 positioned at the upper position have stirring and wall breaking effects, so that the cell wall in the grinding half frame is broken as much as possible, a stirring vortex with larger diameter is formed from the top of the grinding half frame, however, if the inner and outer tooth grinding discs 47 also rotate at the same rotation speed completely and coaxially, the cell wall breaking effect is poor, but the output of the inner and outer tooth grinding discs 47 with different rotation speeds can cause vortex turbulence or smaller vortex to be formed at the lower part of the grinding half frame, and the vortex is rubbed with each other, so that the flowability of the yeast mud is enhanced, and the wall breaking effect of the cell wall is also enhanced.

Because the internal and external teeth grinding piece is arranged below the grinding piece, the movement distance can be limited when the screw thread long rod frame moves downwards, and the mesh cloth of the half frame is prevented from being broken by the second wall breaking teeth 471 of the internal and external teeth grinding piece, so that the two mesh cloths are in conflict.

Example 3:

on the basis of the embodiment 1, as shown in fig. 1-13, the embodiment 3 of the invention provides a biological cell wall pretreatment crushing and filtering system, which further comprises a liquid guide mechanism, wherein the liquid guide mechanism is arranged on a threaded long rod frame 43 and comprises a supporting right angle rod 61, a rotating wheel 62, a lantern ring 63 and a spiral plate 64;

The support right angle pole 61 is connected at the bottom of screw thread long pole frame 43 through the bolt, the support right angle pole 61 is located between two abrasive sheets 44, the both sides of support right angle pole 61 all are connected with the rotation wheel 62 in a rotating way, the both sides of support right angle pole 61 all are connected with the lantern ring 63 in a rotating way, lantern ring 63 and rotation wheel 62 fixed connection, two all fixedly connected with screw plate 64 on the outer wall of lantern ring 63.

As can be seen from an analysis of the specific structure of the liquid guiding mechanism, the long threaded rod frame 43 moves downward and drives the supporting right angle rod 61 to move downward, 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, the rotating wheel 62 and the spiral plate 64 move downward and contact with the bottom of the inner side of the grinding half frame 54, and the long threaded rod frame 43 rotates and drives the supporting right angle rod 61 to rotate;

The rotation of the supporting right-angle rod 61 drives the rotating wheel 62, the lantern ring 63 and the spiral plate 64 to rotate together, the rotating wheel 62 rotates and rotates along the bottom of the inner side of the grinding half frame 54, and the rotating wheel 62 rotates and drives the lantern ring 63 and the spiral plate 64 to rotate together; since the rotation of the two grinding sheets 44 can squeeze the yeast cells to the middle of the two grinding half frames 54, the two spiral plates 64 automatically guide the yeast cell solution in the middle of the two grinding half frames 54 to the surroundings, so that the yeast cells concentrated in the middle of the two grinding half frames 54 are spread out, the two grinding sheets 44 can grind the yeast cells more fully when rotating, the cell walls of the yeast cells are crushed more thoroughly, and substances in the yeast cells are released more fully, so that the cell wall crushing effect of the yeast cells is effectively improved;

At the same time, the upward reset of the long threaded rod frame 43 drives the supporting right angle rod 61 to upward reset, the upward reset of the supporting right angle rod 61 drives the rotating wheel 62, the lantern ring 63 and the spiral plate 64 to upward reset together, and the upward reset of the rotating wheel 62 and the spiral plate 64 is separated from contact with the grinding half frame 54.

Example 4:

On the basis of the embodiment 2, as shown in fig. 1-10, the vibration device is further included, and the vibration devices are arranged on both the supporting frames 2;

The vibration mechanism comprises a hammer head rod 71, a torsion spring II 72, a sawtooth plate 73 and a mandril 74; the two support frames 2 are rotatably connected with hammer head rods 71, the hammer head rods 71 are located below the grinding half frame 54, torsion springs II 72 are connected between the hammer head rods 71 and the support frames 2, the lower portions of the two rack long rods 52 are fixedly connected with sawtooth plates 73, the two hammer head rods 71 are connected with ejector rods 74 through hinges, and the sawtooth plates 73 are located above the ejector rods 74.

As can be seen from analyzing the specific structure and working principle of the vibration mechanism, the rack long rod 52 moves downwards and drives the serration plate 73 to move downwards, the serration plate 73 moves downwards and drives the ejector rod 74 to swing downwards, the ejector rod 74 swings downwards and drives the hammer head rod 71 to swing downwards, the torsion spring II 72 is twisted, the serration plate 73 moves downwards and does not push the ejector rod 74 any more, the torsion spring II 72 resets and drives the hammer head rod 71 and the ejector rod 74 to swing upwards together, at the moment, the two grinding half frames 54 also swing downwards, the hammer head rod 71 swings upwards rapidly and strikes the bottom of the grinding half frame 54, and the serration plate 73 continues to move downwards and pushes the ejector rod 74 to swing downwards again;

Repeatedly, the bottom of the grinding half frame 54 is continuously knocked, and residual yeast cells in the grinding half frame 54 are continuously vibrated, so that some residual yeast cells adhered in the grinding half frame 54 flow into the flow guiding frame 1 along with the solution, and waste of yeast mud is avoided; the rack bar 52 continuously pushes the ejector pin 74 to swing upward when moving upward, and is out of contact with the ejector pin 74.
