Description

Technical Field

[0001] The utility model relates to the technical field of fermentation tanks, and in particular to a solid-liquid separation type fermentation tank. Background Art

[0002] Fermentation tanks are widely used in beverage, chemical, food, dairy, condiments, brewing, pharmaceutical and other industries. The products obtained after fermentation of the fermented substances are mostly solid-liquid mixtures. The solid-liquid mixture in the fermentation tank needs to be separated. Usually, the staff installs a filter at the outlet at the bottom of the fermentation tank. The liquid in the fermentation tank is discharged from the fermentation tank after passing through the filter. The solids accumulate above the filter. The staff needs to open the slag discharge door that closes the slag discharge port and clean the solid residue on the filter, which is a cumbersome operation.

[0003] In this regard, the Chinese patent publication number CN219449653U discloses "a solid-liquid separation fermentation tank, comprising: a tank body, a bottom wall of which is provided with a discharge hole; a turntable, horizontally rotatably connected to the bottom of the tank body, and the top surface is sealed and in contact with the bottom wall of the tank body; the turntable is provided with a sealing part, a discharge part and a filter part, and the sealing part, the discharge part and the filter part are distributed at intervals around the rotating shaft of the turntable; a driving part is provided on the tank body, and the output end is connected to the rotating shaft."

[0004] The above patent drives the turntable to rotate by a driving member, and adjusts the turntable to a liquid discharge state in which the filter part is aligned with the discharge hole. The liquid in the tank body flows out of the tank body after passing through the filter part. After the liquid is discharged, the driving member drives the turntable to rotate again, and adjusts the turntable to a solid discharge state in which the discharge part is aligned with the discharge hole. At this time, the solids accumulated at the bottom of the tank body are discharged from the tank body through the discharge hole under the action of their own gravity. However, when the filter part filters the material, the solids will accumulate on the filter screen, which can easily cause the filter screen to be blocked, which makes it impossible to completely discharge the liquid. Even after multiple filtrations, it is impossible to determine whether the solids and liquid are completely separated. It is easy to cause the solids to be discharged together with the liquid, thereby causing waste of liquid materials.

[0005] In view of this, the utility model proposes a solid-liquid separation fermentation tank. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figures 1 to 6 As shown, this embodiment proposes a solid-liquid separation fermentation tank, including a tank body 1, a discharge assembly 2 is provided at the outlet end of the tank body 1, a mounting frame 3 is fixedly connected to the outside of the tank body 1, a solid-liquid separation mechanism 4 is provided on the inside of the mounting frame 3, and the solid-liquid separation mechanism 4 includes a rotating shaft 41, the rotating shaft 41 is rotatably connected to the inside of the mounting frame 3, the bottom end of the rotating shaft 41 is fixedly connected to a rotating seat 42, and the outer edge of the rotating seat 42 is slidably connected to a plurality of movable plates 43 distributed at equal angles around the rotating seat 42. If One end of the top of the dry movable plate 43 is fixedly connected to a filter plate 44, which contacts the outlet end of the discharge component 2 to drive the discharge component 2 to guide the material to the filter plate 44 for solid-liquid separation. The bottom of the mounting frame 3 is fixedly connected to an arc-shaped protrusion 45, and the bottom of the movable plate 43 is provided with a top pressure piece 46 which contacts the arc-shaped protrusion 45 to drive the filter plate 44 to contact the outlet end of the discharge component 2. The top of the rotating shaft 41 is provided with a driving piece 47 for driving the rotating shaft 41 to rotate intermittently.

[0028] The driving member 47 drives the rotating shaft 41 to rotate intermittently, so that the rotating seat 42 drives all the movable plates 43 to rotate intermittently in the circumferential direction. When one of the movable plates 43 rotates to the position of the outlet end of the discharge component 2, the top pressure member 46 and the arc pressure head 463 come into conflict, which makes the filter plate 44 come into conflict with the outlet end of the discharge component 2, so that the discharge component 2 guides the material to the filter plate 44 for solid-liquid separation.

[0029] Furthermore, the discharging assembly 2 includes a discharging hopper 21, the bottom end of the inner side of the discharging hopper 21 is fixedly connected to a bracket 22, the middle part of the bracket 22 is slidably connected to a slide bar 23 that passes through the bracket 22, the top of the slide bar 23 is fixedly connected to a baffle plate 24 for sealing the outlet end of the discharging hopper 21, and the bottom of the slide bar 23 is fixedly connected to a pressure block 25, which drives the baffle plate 24 to disengage from the outlet end of the discharging hopper 21 by contacting any one of the filter plates 44, and a first spring 26 is sleeved on the slide bar 23, the top end of the first spring 26 contacts the bracket 22, and the bottom end of the first spring 26 contacts the pressure block 25. The discharging hopper 21 is a frustum structure that is wide at the top and narrow at the bottom, and the diameter of the pressure block 25 is smaller than the inner diameter of the outlet end of the discharging hopper 21. By acting upward on the pressing block 25, the slide rod 23 moves upward, which enables the material blocking plate 24 to move upward and disengage from the outlet end of the discharge hopper 21, so that the outlet end of the discharge hopper 21 can discharge the material, allowing the filter plate 44 to filter the material to separate the solid and liquid.

[0030] Furthermore, the movable plate 43 has an L-shaped structure. The filter plate 44 is fixedly connected to the horizontal section of the movable plate 43. A slider 431 is fixedly connected to one side of the vertical section of the movable plate 43. A sliding groove 421 that matches the slider 431 is formed on the outer side of the rotating base 42. The slider 431 is slidably connected to the inner wall of the corresponding sliding groove 421. The slider 431 guides the movable plate 43 by sliding along the sliding groove 421, so that the movable plate 43 can move stably.

[0031] Furthermore, the pressing member 46 includes a fixed plate 461, which is fixedly connected to the bottom of the rotating seat 42. The outer edge of the rotating seat 42 is slidably connected to a number of top rods 462 that pass through the rotating seat 42. The number of top rods 462 corresponds one-to-one to the number of movable plates 43. The top ends of the number of top rods 462 are fixedly connected to the corresponding movable plates 43. The bottom ends of the number of top rods 462 are all fixedly connected to the arc-shaped pressure heads 463. The arc-shaped pressure heads 463 intermittently conflict with the arc-shaped protrusions 45 by cooperating with the rotation of the rotating seat 42. The number of top rods 462 are all provided with second springs 464. The top ends of the number of second springs 464 conflict with the fixed plate 461, and the bottom ends of the number of second springs 464 conflict with the arc-shaped pressure heads 463.

[0032] The rotation of the rotating shaft 41 can make the rotating seat 42 rotate, so that all the movable plates 43 rotate circumferentially. At the same time, the fixed plate 461 rotates synchronously with the rotating seat 42, which makes all the ejector rods 462 drive the arc-shaped pressure heads 463 to rotate circumferentially. When one of the movable plates 43 rotates to the position of the outlet end of the discharge assembly 2, the arc-shaped pressure head 463 corresponding to the movable plate 43 conflicts with the arc-shaped protrusion 45, which makes the arc-shaped pressure head 463 move upward under the action of the arc-shaped protrusion 45. At this time, the second spring 464 is compressed to accumulate potential energy, which makes the ejector rod 462 drive the arc-shaped pressure head 463 to rotate circumferentially. The movable plate 43 is moved upward, so that the filter plate 44 on the movable plate 43 comes into contact with the outlet end of the discharge component 2, so that the discharge component 2 guides the material to the filter plate 44 for solid-liquid separation, and the solid will remain on the top of the filter plate 44; when the arc-surface pressure head 463 is disengaged from the arc-shaped protrusion 45, the second spring 464 releases potential energy, so that the movable plate 43 moves downward to the initial position, and the filter plate 44 is disengaged from the outlet end of the discharge component 2 and staggered with the outlet end of the discharge component 2, so that the filter plate 44 brings out the solid, thereby facilitating the cleaning of the solid on the filter plate 44.

[0033] Furthermore, the driving member 47 includes a rotating plate 471, which is fixedly connected to the top of the rotating shaft 41. The outer edge of the rotating plate 471 is provided with a plurality of docking grooves 472 corresponding to the movable plate 43. A motor 473 is fixedly installed on the inner side of the mounting frame 3. The output shaft of the motor 473 is fixedly connected to an incomplete rotating wheel 474. The top of the incomplete rotating wheel 474 is fixedly connected to a connecting plate 475. One end of the bottom of the connecting plate 475 is fixedly connected to a docking block 476. The docking block 476 intermittently slides with any one of the docking grooves 472 by cooperating with the rotation of the connecting plate 475. The incomplete rotating wheel 474 is tangent to the outer wall of the rotating plate 471, and the diameter of the incomplete rotating wheel 474 is larger than the diameter of the rotating plate 471.

[0034] Working principle: First, the motor 473 drives the incomplete rotating wheel 474 to rotate, which makes the connecting plate 475 drive the docking block 476 to rotate circumferentially. When the docking block 476 slides with one of the docking grooves 472, the rotating plate 471 rotates. When the docking block 476 disengages from the docking groove 472, the rotating plate 471 stops rotating. When the docking block 476 slides with the next docking groove 472, the rotating plate 471 rotates the same angle again. In this cycle, the rotating plate 471 can rotate intermittently, which makes the rotating shaft 41 rotate intermittently, so that the rotating seat 42 drives all the movable plates 43 to rotate intermittently circumferentially, so that the fixed plate 461 follows the rotating seat 42 to rotate synchronously and intermittently, so that all the ejector rods 462 drive the arc surface pressure head 463 to rotate intermittently.

[0035] When the second spring 464 is compressed and the potential energy is accumulated, the push rod 462 drives the movable plate 43 to move upward, thereby making the filter plate 44 on the movable plate 43 contact the pressure block 25 at the outlet end of the discharge hopper 21. The pressure block 25 is driven by the pressure to drive the slide bar 23 to move upward, which makes the baffle plate 24 move upward and disengage from the outlet end of the discharge hopper 21. At this time, the first spring 26 is compressed and the potential energy is accumulated, which makes the outlet end of the discharge hopper 21 able to discharge the material, so that the filter plate 44 filters the material to separate the solid and liquid, and the solid will remain on the top of the filter plate 44.

[0036] When the rotating plate 471 rotates, the movable plate 43 rotates synchronously and deviates from the outlet end of the discharge hopper 21, and the arc pressure head 463 disengages from the arc-shaped protrusion 45, so that the second spring 464 releases the potential energy, which causes the arc pressure head 463 to drive the push rod 462 to move downward, so that the movable plate 43 moves downward, and also causes the filter plate 44 to move downward and disengage from the pressure block 25. At this time, the first spring 26 releases the potential energy to cause the slide bar 23 to move downward, thereby causing the baffle plate 24 to cooperate with the outlet end of the discharge hopper 21 to block the material from being discharged. In this way, the filter plate 44 can be completely deflected and disengaged from the outlet end of the discharge hopper 21, and it is convenient to clean the solids on the top of the filter plate 44. In this cycle, all filter plates 44 can intermittently conflict with the outlet end of the discharge hopper 21 for solid-liquid separation, and then the separated solids are taken out for cleaning. The whole process will not cause the problem of liquid and solid being discharged together, which greatly improves the solid-liquid separation effect.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
