Description
Technical Field
[0001] This utility model belongs to the field of fermentation tank technology, specifically a fermentation tank with solid-liquid separation function. Background Technology
[0002] In food processing, biopharmaceuticals, wastewater treatment, and agricultural waste recycling, fermentation is a core process for converting organic materials. As a key piece of equipment in the fermentation process, the structural design of the fermentation tank directly affects fermentation efficiency, product separation costs, and system operational stability. Traditional fermentation tanks commonly suffer from problems such as "solid-liquid mixed discharge, high energy consumption for subsequent separation," and "solid residue affecting continuous fermentation." Especially in scenarios such as high-concentration organic wastewater treatment and solid-matrix fermentation, incomplete solid-liquid separation leading to resource waste and equipment wear has become a common industry challenge.
[0003] In traditional fermentation tanks, the filter screen is prone to clogging during solid-liquid separation, resulting in poor water permeability and thus affecting separation efficiency.
[0004] Therefore, this utility model provides a fermentation tank with solid-liquid separation function. Utility Model Content
[0005] To overcome the shortcomings of existing technologies and solve at least one of the problems mentioned in the background art, a fermentation tank with solid-liquid separation function is proposed.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A fermentation tank with solid-liquid separation function, comprising a bottom plate; a fermentation tank is fixedly installed on the top of the bottom plate, and a support base is fixedly installed on the bottom of the bottom plate; a snap-fit assembly is provided on the top of the fermentation tank, and a separation assembly is provided on the top of the fermentation tank; a support mechanism is provided on the top of the support plate, and a rotating mechanism is provided on the bottom of the support mechanism; a transmission mechanism is provided on the bottom of the support mechanism, and a stirring mechanism is provided on the bottom of the support mechanism; the snap-fit assembly includes a slot and a block; the slot is opened on both sides of the top of the fermentation tank, and the block is movably snapped onto the inner wall of the top of the fermentation tank through the slot; the cooperation of the slot and the block enables the support plate to remain stable during use, preventing it from shaking, and the slot also allows the user to accurately align the support plate with the fermentation tank.
[0007] Preferably, the separation component includes a support plate and a separation filter. The support plate is fixedly installed on the top of the clamping block, and the bottom of the support plate away from the clamping block is fixedly installed with the separation filter. The separation filter is located on the inner wall of the fermenter. In this scheme, the combined use of the support plate and the separation filter can scoop out the solids inside the fermenter, so that the solid and liquid can be separated, improving the practicality of the equipment.
[0008] Preferably, the support mechanism includes a first U-shaped bracket, a ball bearing, and a second U-shaped bracket. The first U-shaped bracket is fixedly installed on the top of the support plate, and the inner wall of the top of the first U-shaped bracket is rotatably installed with the ball bearing. The second U-shaped bracket is fixedly installed in the middle of the top of the first U-shaped bracket. In this scheme, the cooperation of the first U-shaped bracket and the second U-shaped bracket can provide stable support for the rotating mechanism, ensuring that the rotating mechanism can remain stable during rotation. The ball bearing can reduce the friction between the limiting plate and the support bracket of the support mechanism during rotation, thereby improving its service life.
[0009] Preferably, the rotating mechanism includes a motor, a limiting plate, and a rotating shaft. The motor is fixedly installed on the inner wall of the second U-shaped bracket, and the limiting plate is fixedly installed on the output end of the motor at the bottom. The limiting plate is located above the ball bearing, and the bottom of the limiting plate is fixedly installed with the rotating shaft. The rotating shaft is located on the inner wall of the first U-shaped bracket and is slidably installed with the first U-shaped bracket. In this scheme, the coordinated use of the motor, the limiting plate, and the rotating shaft can drive the transmission mechanism to rotate, providing sufficient power for its use and ensuring that the machine can operate normally.
[0010] Preferably, the transmission mechanism includes connecting rods, a rotating ring, and fixed long rods. Four sets of connecting rods are arranged in a ring and fixedly mounted on the bottom of the rotating shaft surface. The side of the connecting rod away from the rotating shaft is fixedly mounted to the rotating ring. Three sets of fixed long rods are arranged in a ring and fixedly mounted on the bottom of the rotating ring. In this configuration, the coordinated use of the connecting rods, rotating ring, and fixed long rods enables the agitation mechanism to rotate, thus agitating the solids inside the separation filter.
[0011] Preferably, the agitation mechanism includes scrapers, agitating plates, and through holes. Two sets of scrapers are fixedly installed on both sides of a fixed long rod. Three sets of agitating plates are longitudinally fixed on the side of the fixed long rod away from the separating filter screen. Through holes are provided on the surface of each agitating plate. In this design, the scrapers can continuously scrape the inner wall of the separating filter screen by rotating the fixed long rod, preventing material from adhering to the inner wall and causing blockage. The combined use of the agitating plates and through holes can agitate the solid material on the inner wall of the separating filter screen by rotation, preventing material from accumulating at the bottom of the separating filter screen. During the upward movement of the separating filter screen, its filtration efficiency can remain at its optimal state.

On both sides of the top, the locking blocks 42 are movably engaged with the inner wall of the top of the fermenter 2 through the opening of the locking slots 41; the separation assembly 5 includes a support plate 51 and a separation filter 52. The support plate 51 is fixedly installed on the top of the locking blocks 42, and the bottom of the support plate 51 away from the locking blocks 42 is fixedly installed with the separation filter 52. The separation filter 52 is located on the inner wall of the fermenter 2. The support mechanism 6 includes a first U-shaped bracket 61, a ball bearing 62, and a second U-shaped bracket 63. The first U-shaped bracket 61 is fixedly installed on the top of the support plate 51, and the inner wall of the top of the first U-shaped bracket 61 is rotatably installed with the ball bearing 62. The U-shaped bracket 63 is fixedly installed in the middle of the top of the first U-shaped bracket 61. The rotating mechanism 7 includes a motor 71, a limiting plate 72, and a rotating shaft 73. The motor 71 is fixedly installed on the inner wall of the second U-shaped bracket 63. The limiting plate 72 is fixedly installed at the output end of the bottom of the motor 71. The limiting plate 72 is located above the ball bearing 62. The bottom of the limiting plate 72 is fixedly installed with the rotating shaft 73. The rotating shaft 73 is located on the inner wall of the first U-shaped bracket 61 and is slidably installed with the first U-shaped bracket 61. The transmission mechanism 8 includes a connecting rod 81, a rotating ring 82, and a fixed long rod 83. The connecting rod 81 is provided in four sets. 81 is fixedly installed in a ring at the bottom of the surface of the rotating shaft 73. The side of the connecting rod 81 away from the rotating shaft 73 is fixedly installed with the rotating ring 82. Three sets of fixed long rods 83 are provided, and the three sets of fixed long rods 83 are fixedly installed in a ring at the bottom of the rotating ring 82. The stirring mechanism 9 includes scraper 91, stirring plate 92 and through hole 93.

[0027] like Figures 1 to 6As shown, the cooperation of the slot 41 and the block 42 ensures the stability of the support plate 51 during use, preventing it from shaking. The slot 41 also allows the user to accurately align the support plate 51 with the fermentation tank 2. The cooperation of the support plate 51 and the separating filter screen 52 allows for the removal of solids from the fermentation tank 2, enabling solid-liquid separation and improving the equipment's usability. The cooperation of the first U-shaped bracket 61 and the second U-shaped bracket 63 provides stable support for the rotating mechanism 7, ensuring its stability during rotation. The ball bearing 62 reduces friction between the limiting plate 72 and the support mechanism 6 bracket during rotation, extending its service life. The motor 71, the limiting plate 72, and the rotating shaft... The combined use of 73 enables the drive transmission mechanism 8 to rotate, providing sufficient power for its operation and ensuring normal mechanical operation. The combined use of connecting rod 81, rotating ring 82, and fixed long rod 83 enables the agitation mechanism 9 to rotate, thus agitating the solids inside the separation filter screen 52. The scraper 91, through the rotation of the fixed long rod 83, continuously scrapes the inner wall of the separation filter screen 52, preventing material from adhering to the inner wall of the separation filter screen 52 and causing blockage. The combined use of agitator 92 and through hole 93, through rotation, agitates the solid material on the inner wall of the separation filter screen 52, preventing material from accumulating at the bottom of the separation filter screen 52. During the upward process, the filtration efficiency of the separation filter screen 52 can be maintained at its optimal state.
[0028] Working principle: During operation, first place the base plate 1 on a flat surface, then place the material into the separation filter 52, and then pour appropriate amount of water into the fermentation tank 2 for fermentation. When solid-liquid separation is required, first start the motor 71 to drive the limiting plate 72 to rotate. The rotation of the limiting plate 72 will drive the rotating shaft 73 to rotate. The rotation of the rotating shaft 73 will drive multiple sets of connecting rods 81 to rotate. The rotation of the connecting rods 81 will cause the rotating ring 82 to rotate. When the rotating ring 82 rotates, it will drive the fixed long rod 83 to rotate. The rotation of the fixed long rod 83... The stirring plate 92 will agitate the solids inside the separation filter 52, while the scraper 91 will scrape the inner wall of the separation filter 52. When the solids inside the separation filter 52 are scraped, they will float in the water. At this time, the user needs to use a lifting device to lift the support plate 51 upward. Since the solids inside the fermentation tank 2 are not piled up, the water filtration effect of the separation filter 52 will be better when it is lifted. As the separation filter 52 is continuously lifted, the solids inside the fermentation tank 2 will be scooped out, while the liquid will remain inside the fermentation tank 2, thus completing the solid-liquid separation.
