DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0023] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0024] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , a fermentation liquid filtering device; comprising a box body 1 and a plurality of supporting legs 2 fixedly mounted on the lower surface of the box body 1, the upper portion of the box body 1 is open, a drainage mechanism is provided at the left bottom of the box body 1, the drainage mechanism comprises a discharge port 3 and a plug 19, the discharge port 3 is fixedly mounted at the left lower portion of the box body 1, a plug 19 is matched and mounted on the discharge port 3, the plug 19 is used to block the discharge port 3 and control the on and off of the discharge port 3.

[0025] A motor 4 is fixedly installed on the outer wall of the front side of the box body 1. The motor 4 is a reversible motor with the function of forward and reverse rotation. Two belts 5 are installed on the transmission sleeve on the output shaft of the motor 4. Two lead screws 7 are rotatably installed in the box body 1, and one end of the lead screw 7 extends through the box body 1 and is connected to the belt 5. The two lead screws 7 are arranged up and down and are located on the same vertical line. Two polished rods 9 are fixedly installed in the box body 1, and the two polished rods 9 are arranged one by one with the two lead screws 7. The installation height of the polished rod 9 is consistent with the installation height of the corresponding lead screw 7, and the polished rod 9 and the lead screw 7 are respectively arranged on both sides of the inside of the box body 1.

[0026] Two scrapers 11 are arranged at intervals in the upper and lower parts of the box body 1. The scrapers 11 include a support arm 111, a guide sleeve 112, a scraper protrusion 113, a scraper plate 114, a scraper spring 115 and a baffle guide rod 116. One end of the support arm 111 is fixedly sleeved in the middle of the guide sleeve 112. The guide sleeve 112 has a certain length, and both ends of the guide sleeve 112 protrude from the support arm 111. The lead screw 7 is threadedly sleeved with the guide sleeve 112, and the other end of the support arm 111 is slidably installed with the polished rod 9. The polished rod 9 plays a guiding role to prevent the support arm 111 from rotating under the drive of the lead screw 7. When the lead screw 7 rotates, the support arm 111 moves axially along the lead screw 7.

[0027] There are multiple scraper springs 115, which are spaced between the support arm 111 and the scraper plate 114. The upper end of the scraper spring 115 is fixedly mounted on the support arm 111, and the lower end of the scraper spring 115 is fixedly mounted on the scraper plate 114. A sliding column 117 is sleeved inside the scraper spring 115. The top end of the sliding column 117 is fixedly mounted on the support arm 111, and the bottom end of the sliding column 117 is movably plugged with the scraper plate 114. The sliding column 117 plays a guiding role to limit the mutual movement between the support arm 111 and the scraper plate 114 in the horizontal direction.

[0028] The scraper protrusion 113 is fixedly mounted on the bottom surface of the support arm 111, and the scraper protrusion 113 and the guide sleeve 112 are located at the same end of the support arm 111. There are two baffle guide rods 116, which penetrate the scraper plate 114 and are fixedly mounted thereon. The two ends of the baffle guide rods 116 extend out of the scraper plate 114. In the initial state, the support arm 111 is not at the limit position at both ends of the lead screw 7, the baffle guide rods 116 do not contact the baffle 16, and the baffle 16 is in a closed state. Top springs 14 are fixedly mounted on the four corners of the inner wall of the box body 1 below the scraper plate 114, and a screen 12 is fixedly mounted on the top of the top spring 14. A screen protrusion 121 is fixedly mounted on one side of the upper surface of the screen 12 at intervals. The screen protrusion 121 and the scraper protrusion 113 are arranged on the same side of the box body 1, and the lower end of the scraper protrusion 113 and the upper end of the screen protrusion 121 are both in the shape of arc surfaces. In the initial state, the screen 12 is in close contact with the scraper plate 114, the scraper protrusion 113 is in contact with the screen 12, and the scraper spring 115 is in a compressed state. When the scraper protrusion 113 moves, the scraper protrusion 113 will contact the screen protrusion 121. When the lowest point of the scraper protrusion 113 contacts the highest point of the screen protrusion 121, the scraper protrusion 113 will press the screen protrusion 121, and the top spring 14 will be in a compressed state, so that the screen 12 drops. When the scraper protrusion 113 continues to move, the lowest point of the scraper protrusion 113 gradually separates from the highest point of the screen protrusion 121, and the top spring 14 rebounds, and the screen 12 is reset. When the scraper protrusion 113 continues to move and contacts the next screen protrusion 121, the cycle repeats. During this process, the scraper protrusion 113 moves at a relatively fast speed, and the scraper protrusion 113 can quickly contact different screen protrusions 121, thereby driving the screen 12 to move up and down quickly and produce a vibration effect. When the lowest point of the scraper protrusion 113 contacts the highest point of the screen protrusion 121, the screen 12 moves downward relative to the initial position, and the compressed scraper spring 115 stretches and pushes the scraper plate 114 to move downward, so that the scraper plate 114 is close to the screen 12 and moves downward with the screen 12. Since the scraper protrusion 113 and the screen protrusion 121 are small in size, the stroke of the screen 12 moving up and down during the vibration process is also small, which makes the scraper plate 114 always close to the screen 12.

[0029] Two discharging mechanisms are provided on both sides of the box body 1, and the discharging mechanisms include a slag outlet 15, a baffle 16 and a rotating shaft 17. There are four slag outlets 15, and the slag outlets 15 are fixedly installed in the middle of the left and right sides of the box body 1. In the initial state, the bottom surface of the slag outlet 15 is flush with the upper surface of the screen 12, and the baffle 16 is hinged to the slag outlet 15 through the rotating shaft 17. A torsion spring is provided between the baffle 16 and the rotating shaft 17, so as to realize the elastic hinge of the baffle 16 and the slag outlet 15. In the normal state, the baffle 16 is close to the slag outlet 15 to prevent the fermentation liquid from flowing out directly from the slag outlet 15.

[0030] Two scrapers 11 are provided, and two screens 12 cooperating with the support arm 111 are also provided, and the two screens 12 are arranged one above and one below. The aperture of the upper screen 12 is larger than that of the lower screen 12. The lower screen 12 filters more finely, and the fermentation liquid is double-filtered, which improves the filtering accuracy.

[0031] When in use, first plug the discharge port 3 with the plug 19, and pour in an appropriate amount of fermentation liquid to be filtered. Start the motor 4, which drives the lead screw 7 to rotate through the belt 5. The lead screw 7 rotates and drives the guide sleeve 112 to move axially along the lead screw 7. The support arm 111 fixedly mounted with the guide sleeve 112 drives the scraper plate 114 to scrape the fermentation liquid on the screen 12 and move it. At the same time, the scraper protrusion 113 gradually contacts the screen protrusion 121 and drives the screen 12 to vibrate. Under the vibration of the screen 12, the liquid is accelerated to pass through the screen 12, and the remaining fermentation liquid residue is scraped and pushed by the scraper plate 114. As the scraper plate 114 moves, the fermentation liquid residue is scraped by the scraper plate 114 to the slag discharge port 15 on one side of the box body 1. When the scraper plate 114 is a certain distance away from the slag outlet 15, the baffle guide rod 116 on the scraper plate 114 pushes the baffle plate 16 away. After the baffle plate 16 is pushed away, the fermentation liquid residue is discharged from the outside of the box body 1 through the slag outlet 15 as the scraper plate 114 pushes. When the scraper plate 11 as a whole reaches one side of the box body 1, the rotation direction of the motor 4 is adjusted, the scraper plate 11 moves in the opposite direction, and the screen 12 vibrates again. At this time, new fermentation liquid is poured into the box body 1. The device as a whole repeats the above actions to perform a new round of filtration.

[0032] After several filtrations, when the filtrate is stored to a certain amount, the plug 19 is pulled out and the filtrate is discharged from the discharge port 3.

[0033] By coordinating the lead screw 7, the scraper 11, the screen 12 and the top spring 14, the scraper plate 114 pushes the fermentation liquid for filtration while the screen 12 generates vibration to accelerate the filtration of the fermentation liquid, thereby improving the filtration efficiency. The device can simultaneously push, scrape and vibrate the fermentation liquid only by rotating the motor 4, and can quickly complete the filtration work only by a single power source. The setting of a single power source makes the structure of the device itself simpler and the cost lower. At the same time, the single power source reduces the probability of failure of the device during operation, improves durability, and improves the degree of automation of the device.

[0034] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
