Description

Technical Field

[0001] This utility model relates to the field of food fermentation tank technology, and in particular to a food fermentation tank that facilitates solid-liquid separation. Background Technology

[0002] Food fermentation tanks are key pieces of equipment used in microbial fermentation processes and are widely used in the food, beverage, and pharmaceutical industries. They provide a suitable growth environment for microorganisms, enabling them to carry out metabolic activities under controlled conditions, thereby producing various products with specific functions.

[0003] Publication (Announcement) No.: CN221166511U discloses a food fermentation tank with solid-liquid separation function. This food fermentation tank with solid-liquid separation function, through the setting of the observation component, allows the liquid and solid mixture produced by fermentation to enter the connecting pipe through the pressure generated by stirring during the operation of the fermentation tank, and then enter the storage pipe. The fermentation situation inside the tank can be observed through the visual observation window, so as to facilitate timely processing and improve the intuitive understanding of the fermentation situation.

[0004] Currently, in some food fermentation tanks, after food fermentation, the liquid is filtered downwards from the internal filter screen. At this point, the liquid is drawn away through a pipe at the bottom of the tank for more detailed solid-liquid separation. However, the internal filter screen is prone to clogging after repeated use. For clogged filter screens, the solid waste is usually washed away and diluted before being pumped out for cleaning. However, stubborn dirt often remains in the many mesh openings of the filter screen and is difficult to clean quickly. As a result, cleaning the internal filter screen of the food fermentation tank often requires a long rinsing time. Therefore, we propose a food fermentation tank that facilitates solid-liquid separation. Utility Model Content

[0005] The main objective of this invention is to provide a food fermentation tank that facilitates solid-liquid separation. A cleaning mechanism is installed on the tank body near the filter screen. This mechanism consists of three sets of single-ended arched tubes extending into the tank. A T-shaped guide plate carries an ultrasonic vibrator, which transmits ultrasonic waves to the filter screen, which is immersed in clean water, through the single-ended arched tubes. The ultrasonic cavitation effect accelerates the removal of dirt from the filter screen surface, thereby improving the cleaning efficiency of the fermentation tank body and ensuring the cleanliness and efficiency of the filter screen inside the fermentation tank. Furthermore, when the single-ended arched tubes transmit ultrasonic vibrations, a screen pressing frame precisely transmits the vibration energy to the filter screen surface, avoiding blind spots in cleaning and significantly improving the solid-liquid separation and cleaning efficiency of the dirt on the filter screen. This effectively solves the problems in the prior art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A food fermentation tank for easy solid-liquid separation includes a fermentation tank body. A filter screen is installed on the inner wall of the fermentation tank body near its bottom drain pipe. The tank also includes a screen cleaning mechanism, which comprises a liner plate, an outer plate, a single-mouth arched cylinder, a T-shaped guide plate, an ultrasonic vibrator, and a screen pressing frame. Liner plates and outer plates are welded to both sides of the fermentation tank body above the filter screen, respectively. The inner arc surface of the liner plate has protruding lining claws that are welded into the interior of the fermentation tank body. The surface of the outer plate is welded with inserts for the fermentation tank. The main body has a single-hole arched cylinder inside, and the cylinder body of the single-hole arched cylinder is welded to the fermentation tank body. The outer cylinder body of the single-hole arched cylinder away from the outer connecting plate is pressed and welded to the lining claw surface of the insert plate. The straight inner cylinder wall of the single-hole arched cylinder is recessed and has a T-shaped guide groove for mounting a T-shaped guide plate. The surface of the T-shaped guide plate is welded with studs for screwing and installing ultrasonic vibrators. A lifting and inserting post is inserted between the T-shaped guide plate and the groove wall of the T-shaped guide groove. A pressing frame that presses against the surface of the filter screen is welded to the bottom cylinder wall of the single-hole arched cylinder.

[0008] Furthermore, the main frame plate of the pressing frame is welded to the bottom of the single-arch cylinder, and support plates are symmetrically welded on both sides of the main frame plate of the pressing frame. A through groove is opened between the main frame plate and the support plate of the pressing frame.

[0009] By adopting the above technical solution, the single-hole arch cylinder can press the main frame plate and support plate of the screen pressing frame onto the filter screen to transmit ultrasonic waves, and the main frame plate and support plate of the screen pressing frame have through grooves through which liquid can pass.

[0010] Furthermore, a top corner bracket plate is welded between the vertical cylinder walls of the single-arch cylinder away from the T-shaped guide plate, and the top corner plate head of the top corner bracket plate is welded to the inner arc wall of the single-arch cylinder.

[0011] By adopting the above technical solution, a top corner support plate is welded between the vertical cylinder wall and the inner arc wall inside the single-arch cylinder to provide internal support, thereby improving the deformation resistance of the single-arch cylinder.

[0012] Furthermore, a gap higher than that between the inner corner surface of the top corner bracket plate and the upper plate surface of the T-shaped guide plate is reserved, and the bottom block surface of the ultrasonic vibrator presses against the surface of the T-shaped guide plate.

[0013] By adopting the above technical solution, when the T-shaped guide plate slides into the single-port arch cylinder along the T-shaped guide groove, the ultrasonic vibrator can pass between the top corner support plate and the T-shaped guide plate.

[0014] Furthermore, a fixed hole is vertically opened between the plate and the groove near the opening of the single-mouth arch cylinder of the T-shaped guide plate and the T-shaped guide groove, and a column of the lifting and inserting column is inserted into the fixed hole. An L-shaped handle is welded to the top of the column of the lifting and inserting column.

[0015] By adopting the above technical solution, after the T-shaped guide plate and the T-shaped guide groove are slidably inserted, a lifting post can be inserted at the fixed hole of both for insertion and positioning, preventing the T-shaped guide plate and the T-shaped guide groove from separating. The lifting post has an L-shaped handle that can be hooked by hand, making it convenient to lift and pull up the lifting post.

[0016] Furthermore, the fermenter body surface above the outer plate has three door slots at three points, and three sets of dome cylinders with single-mouth arched cylinders are inserted into the slots.

[0017] By adopting the above technical solution, the three sets of dome cylinders of the single-mouth arch cylinder can be inserted into the fermentation tank body at the three-door slot and supported by the lining plate for welding. Then, the single-mouth arch cylinder can be welded and sealed to the slot wall of the three-door slot.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This invention features a cleaning mechanism installed on the tank body near the filter screen of the fermenter. The cleaning mechanism consists of three sets of single-ended arched tubes that extend into the tank. Then, a T-shaped guide plate carries an ultrasonic vibrator to transmit ultrasonic waves to the filter screen, which is immersed in clean water, through the single-ended arched tubes. The ultrasonic cavitation effect accelerates the removal of dirt from the surface of the filter screen, thereby improving the cleaning efficiency of the fermenter body and ensuring the cleanliness and efficiency of the filter screen inside the fermenter body.

[0020] Furthermore, when the single-port arched cylinder transmits ultrasonic vibrations, the vibration energy is precisely transferred to the filter screen surface of the filter screen plate through the pressure screen frame, avoiding cleaning blind spots and significantly improving the solid-liquid separation and cleaning efficiency of dirt at the filter screen plate.

Detailed Implementation

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figure 1-3 As shown, a food fermentation tank for easy solid-liquid separation includes a fermentation tank body 1. A filter screen 2 is installed on the inner wall of the fermentation tank body 1 near the bottom drain pipe. The tank also includes a screen cleaning mechanism 3, which comprises a liner plate 4, an outer plate 5, a single-mouth arched cylinder 7, a T-shaped guide plate 9, an ultrasonic vibrator 11, and a screen pressing frame 15. Liner plates 4 and outer plates 5 are welded to both sides of the fermentation tank body 1 above the filter screen 2. The inner arc surface of the liner plate 4 has protruding lining claws that are welded into the interior of the fermentation tank body 1. The surface of the outer plate 5 is welded with inserts for the fermentation tank... The single-mouth arched cylinder 7 is located inside the main body 1, and the cylinder body of the single-mouth arched cylinder 7 is welded to the fermentation tank main body 1. The outer cylinder body of the single-mouth arched cylinder 7 away from the outer connecting plate 5 is pressed and welded to the lining claw surface of the insert plate 4. The straight inner cylinder wall of the single-mouth arched cylinder 7 is recessed and provided with a T-shaped guide groove 8 for mounting a T-shaped guide plate 9. The plate surface of the T-shaped guide plate 9 is arranged and welded with studs 10 for screwing and installing an ultrasonic vibrator 11. A lifting and inserting post 13 is inserted between the T-shaped guide plate 9 and the groove wall of the T-shaped guide groove 8. A pressing frame 15 is welded to the bottom cylinder wall of the single-mouth arched cylinder 7 to press against the surface of the filter screen 2.

[0027] The main frame plate of the pressing frame 15 is welded to the bottom of the single-arch cylinder 7, and the main frame plate of the pressing frame 15 is symmetrically welded with support plates on both sides. A through groove is opened between the main frame plate and the support plate of the pressing frame 15.

[0028] By adopting the above technical solution, the single-hole arch cylinder 7 can press the main frame plate and the support plate of the screen pressing frame 15 onto the filter screen 2 to transmit ultrasonic waves, and the main frame plate and the support plate of the screen pressing frame 15 have through grooves through which liquid can pass.

[0029] Among them, a top corner bracket plate 14 is welded between the vertical cylinder wall of the single-mouth arch cylinder 7 away from the T-shaped guide plate 9, and the top corner plate head of the top corner bracket plate 14 is welded to the inner arc wall of the single-mouth arch cylinder 7.

[0030] By adopting the above technical solution, a top corner bracket plate 14 is welded between the vertical cylinder wall and the inner arc wall inside the single-arch cylinder 7 for internal support, thereby improving the deformation resistance of the single-arch cylinder 7.

[0031] Wherein, the inner corner surface of the top corner bracket plate 14 and the upper plate surface of the T-shaped guide plate 9 are reserved with a distance higher than that of the ultrasonic vibrator 11, and the bottom block surface of the ultrasonic vibrator 11 presses against the surface of the T-shaped guide plate 9.

[0032] By adopting the above technical solution, when the T-shaped guide plate 9 slides into the single-mouth arch cylinder 7 along the T-shaped guide groove 8, the ultrasonic vibrator 11 can pass between the top corner support plate 14 and the T-shaped guide plate 9.

[0033] Wherein, a fixed hole 12 is vertically opened between the plate and the groove of the T-shaped guide plate 9 and the T-shaped guide groove 8 near the opening of the single-mouth arch cylinder 7, and a column of the lifting and inserting column 13 is inserted into the fixed hole 12, and an L-shaped handle is welded to the top of the column of the lifting and inserting column 13.

[0034] By adopting the above technical solution, after the T-shaped guide plate 9 and the T-shaped guide groove 8 are slidably inserted, the lifting post 13 can be inserted and positioned at the fixed hole 12 of both to prevent the T-shaped guide plate 9 and the T-shaped guide groove 8 from separating. The lifting post 13 has an L-shaped handle that can be hooked by hand to facilitate lifting and pulling up the lifting post 13.

[0035] Among them, the fermentation tank body 1 above the outer plate 5 has three door slots 6 at three points on its surface, and three sets of dome cylinders with single-mouth arch cylinders 7 are inserted into the slots of the three door slots 6.

[0036] By adopting the above technical solution, the three sets of dome cylinders of the single-mouth arch cylinder 7 can be inserted into the fermenter body 1 at the three-door slot 6 and supported by the insert plate 4 for welding. Then, the single-mouth arch cylinder 7 can be welded and sealed to the slot wall of the three-door slot 6.

[0037] It should be noted that this utility model is a food fermentation tank that facilitates solid-liquid separation. A screen cleaning mechanism 3 is installed on the tank body above the filter screen 2 inside the fermentation tank body 1. When the ultrasonic vibrator 11 is screwed onto the surface of the T-shaped guide plate 9 of the screen cleaning mechanism 3 using studs 10, adhesive can be applied between the ultrasonic vibrator 11 and the T-shaped guide plate 9 to strengthen the bond. Subsequently, under the guidance of professional electrical technicians, the ultrasonic vibrator 11 on the surface of the T-shaped guide plate 9 can be connected to an external ultrasonic generator and a matching controller via a long wire. Then, the T-shaped guide plate 9 can slide into the T-shaped guide groove 8, and the lifting and inserting post 13 is used to secure the T-shaped guide plate 9 to the T-shaped guide groove 8. A pin is inserted and stopped at the fixed hole 12 of the guide groove 8. After the fermented food enters the fermentation tank 1 through the feed pipe at the top of the fermentation tank body 1 for fermentation, the fermentation liquid can flow downwards through the filter screen 2 into the bottom of the fermentation tank body 1. The bottom drainage pipe of the fermentation tank body 1 can be pre-connected with two sets of electric hydraulic valves using a three-way connector. A liquid pump pipe is installed at one set of electric hydraulic valves. When this set of electric hydraulic valves is opened, the liquid in the fermentation tank body 1 can be pumped away. Then, this set of electric hydraulic valves is closed. The other set of electric hydraulic valves is connected to the sewage treatment equipment pipe and opened. Then, cleaning water can be flushed into the fermentation tank body 1 from top to bottom to remove some of the dirt remaining on the surface of the filter screen 2. After being flushed away, the wastewater is discharged through the pipeline to the sewage treatment equipment for further processing. During the internal flushing of the fermentation tank 1, the electric hydraulic valve for wastewater discharge can be closed. As the tank fills with liquid, the ultrasonic vibrator 11 can be activated under the control of an external ultrasonic generator and its controller. The core of the ultrasonic vibrator 11 is a piezoelectric ceramic plate. Under the action of a high-frequency electrical signal, it generates periodic stretching and contracting vibrations due to the inverse piezoelectric effect. The vibration is amplified and transmitted to the water through the T-shaped guide plate 9, the single-hole arch cylinder 7, and the pressure mesh frame 15, forming ultrasonic mechanical waves. The ultrasonic vibration creates instantaneous negative pressure between water molecules, forming tiny vacuum bubbles that produce a cavitation effect, thereby effectively... The filter screen 2 is cleaned by removing bacteria, protein impurities, and other dirt. Technicians can operate it multiple times and set appropriate frequencies and power to ensure improved cleaning efficiency while reducing mechanical wear. With the assistance of ultrasonic cleaning, the dirt on the filter screen 2 is quickly removed. At this time, the electric hydraulic valve for sewage discharge can be opened to pump out the sewage from the fermentation tank body 1. Then, the fermentation tank body 1 can be rinsed, as can the electric hydraulic valve for discharging the fermentation liquid. The electrical components of this invention can be tested multiple times under the guidance of experienced professional electrical technicians to adjust to the appropriate operating time and method.
