Description

Technical Field

[0001] The utility model relates to the technical field of biological enzyme liquid separation devices, in particular to a centrifugal concentration and separation device for biological enzymes. Background Art

[0002] Enzymes are catalytic organic compounds produced by living cells, mostly proteins, with a small fraction being RNA. They are increasingly used in industries such as medicine, textiles, petroleum, food, and papermaking. In existing enzyme production processes, after cells are broken down to produce an enzyme solution, centrifugation is often used to separate the enzyme solution into solids and liquids, thereby concentrating and separating the enzyme solution.

[0003] For example, in Chinese patent CN202322593725.3, a selenium-enriched yeast hydrolysis enzyme liquid microfiltration purification and separation device is provided, including a shell, a shell cover and a microfiltration membrane. A partition is fixedly provided inside the shell, a motor is fixedly provided at the bottom of the shell, a rotating shaft is fixedly provided at the output end of the motor, the upper end of the rotating shaft extends to the top of the partition and is fixedly provided with a turntable, and the microfiltration membrane is detachably provided on the upper surface of the turntable; the shell cover is located at the top of the shell, and two elastic rods are symmetrically provided on the lower surface of the shell cover, and the rod walls of the two elastic rods are fixed with anti-blocking brushes provided in contact with the inner wall of the microfiltration membrane. The structure for driving the microfiltration membrane to rotate is adopted, and the selenium-enriched yeast hydrolysis enzyme can be centrifugally filtered, and the inner wall of the microfiltration membrane can be cleaned at the same time to avoid clogging of the microfiltration membrane.

[0004] In the above technical solution, the turntable drives the microfiltration membrane to rotate through the elastic rod and the anti-blocking brush. The elastic rod applies elastic force to the anti-blocking brush, so that the anti-blocking brush contacts the inner wall of the microfiltration membrane, thereby cleaning the inner wall of the microfiltration membrane and avoiding clogging of the microfiltration membrane.

[0005] However, simply scraping the inner wall of the microfiltration membrane cannot clean the debris stuck in the microfiltration membrane; moreover, the debris scraped off by the anti-clogging brush always remains inside the inner wall of the microfiltration membrane and cannot be discharged in time, thereby reducing the subsequent working efficiency of the microfiltration membrane.

[0017] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0018] Reference Figure 1 As shown, the embodiment of the present application discloses a centrifugal concentration and separation device for biological enzymes, including: a frame 1; a filter component 2, which is a hollow cylindrical component inside and is rotatably arranged on the frame 1 for storing enzyme liquid; a driving component 3, used to drive the filter component 2 to rotate and centrifugally separate the enzyme liquid; a backflush component, which is arranged on the outside of the filter component 2 and is used to spray water onto the outer wall of the filter component 2; a scraping component, which can make a linear reciprocating motion along the axial direction of the filter component 2 and enter / exit the centrifugal component to scrape off debris on the inner wall of the filter component 2; and a suction component, which is used to suck out debris in the filter component 2.

[0019] In the present invention, the backflushing component can be used to spray water onto the outer wall surface of the filter component to backwash the filter component 2, and the debris blocked in the filter component 2 can be flushed back into the inner wall surface of the filter component 2; in addition, the scraping component can be used to scrape off the debris on the inner wall surface of the filter component 2 to clean the inner wall surface of the filter component 2; and the suction component can be used to suck out the debris in the filter component 2 to ensure the subsequent filtering efficiency of the filter component 2.

[0020] It is understandable that the filter component 2 should be made of a filter capable of performing solid-liquid separation on the enzyme solution, and filter holes are provided on the filter screen; of course, in order to meet different filtering requirements, filter holes of different diameters can be provided on the filter component 2.

[0021] In this embodiment, the driving component 3 can be a servo motor, and the output shaft of the servo motor can be connected to the filter component 2 through a coupling. The filter component 2 can be driven to rotate by rotating the output shaft of the servo motor, thereby centrifuging the enzyme solution and completing the concentration.

[0022] Specifically, the filter component 2 may be rotatably disposed on the main body via a turntable bearing.

[0023] Specifically, the backflush assembly includes: a water supply column 41, which is hollow inside, parallel to the central axis of the filter component 2, and is arranged on the frame 1; a plurality of nozzles 42, which are installed in an array on the water supply column 41 along the central axis of the filter component 2; a water supply pump 43, whose water inlet is connected to the water tank through a pipe, and whose water outlet is connected to the water supply column 41 through a pipe.

[0024] It can be understood that by starting the water supply pump 43, the water in the water tank can be transported toward the water supply column 41, and the water is dispersed by the nozzle 42 and sprayed toward the outer wall surface of the filter component 2 to complete the backwashing work.

[0025] Preferably, when the nozzle 42 is spraying water, the driving component 3 should drive the filter component 2 to rotate, so as to complete the backwashing of the filter component 2 in the circumferential direction.

[0026] Among them, the scraping assembly includes: a telescopic component 51, the main body of the telescopic component 51 is arranged on the frame 1 parallel to the central axis of the filter component 2; a push rod 52, which is arranged concentrically with the filter component 2 and fixedly installed on the piston rod of the telescopic component 51; a push plate 53, which is arranged at one end of the push rod 52 and is used to scrape off debris on the inner wall surface of the filter component 2.

[0027] The piston rod of the telescopic component 51 performs telescopic movement, thereby driving the push plate 53 into the filter component 2 to clean the debris on the inner wall surface of the filter component 2 .

[0028] Preferably, the outer contour of the push plate 53 should be designed according to the inner wall contour of the filter component 2 .

[0029] Specifically, the suction assembly includes: a suction channel, which is opened in the push rod 52 along the axial direction of the push rod 52; a suction head 61, which is connected to the suction channel and is located at the end of the push rod 52 close to the filter component 2; and a water pump 62, which is connected to the end of the suction channel away from the suction head 61 through a pipe.

[0030] When the telescopic component 51 drives the push plate 53 to enter the filter component 2, it can also drive the suction head 61 into the filter component 2. The water pump 62 provides negative pressure to the suction channel to suck out the debris in the filter component 2, reducing the accumulation of debris in the filter component 2 and ensuring the subsequent filtration efficiency of the filter component 2.

[0031] Specifically, the device also includes a base 63, which is arranged in the filter component 2. A downwardly concave arc surface is provided on the base 63 to guide the backwash water flow and debris to flow and gather toward the central axis of the base 63, making it easier for the suction head 61 to suck out debris and reduce debris residue.

[0032] Specifically, the device further includes a cover 7 , which is disposed on the main body and covers the filter component 2 , so that the liquid obtained by centrifugal separation of the enzyme solution is temporarily stored between the cover 7 and the filter component 2 .

[0033] It is understood that an output pipe 81 communicating with the interior of the housing 7 is further provided on the main body. A valve is provided on the output pipe 81. By controlling the opening and closing of the valve, the liquid obtained by centrifuging the enzyme solution can be output.

[0034] Specifically, a bracket 82 is further provided above the cover shell 7 , a ball sleeve 83 is provided on the bracket 82 , and the push rod 52 is slidably provided in the ball sleeve 83 .

[0035] In this embodiment, an input pipe 84 is further provided, and an output pipe 81 passes through the bracket 82 and the push plate 53 and extends toward the inside of the filter component 2 for conveying the enzyme solution to be separated into the filter component 2 .

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention. Clearly, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention.
