Description

[0001] The utility model relates to the technical field of silkworm pupa protein peptide production, in particular to an extrusion device of a filtering device for silkworm pupa protein peptide production. Background Technique

[0002] In the production process of silkworm pupa protein peptide, the extrusion device of the filtering device plays a crucial role. It is mainly used for solid-liquid separation of the enzymolyzed mixture to extract high-purity protein peptide. In the production of silkworm pupa protein peptide, common extrusion devices of filtering devices may be plate-and-frame filter presses, chamber filter presses, etc. These devices all have high-efficiency and fast filtering and separation capabilities and can meet the needs of large-scale production.

[0003] The existing filtering device is not convenient for replacing the filter net. Therefore, when cleaning or replacing the filter net with different mesh sizes, it is rather inconvenient, reducing the filtering efficiency of the device and having certain defects.

[0004] The existing patent (publication number: CN220989928U) discloses a membrane filtering device for collagen peptide production, including a bottom plate, an ultrafiltration barrel and a filtering box body. The filtering box body is fixedly installed on one side of the top of the bottom plate. The top of the filtering box body is connected with an upper cover. The inside of the upper cover is connected with a filter net. A booster pump is installed in the middle of the top of the bottom plate. The other side of the top of the bottom plate is fixedly connected with an ultrafiltration box body. By opening the upper cover, putting the filter net into the filtering box body and adjusting the position of the filter net so that the positioning holes are at the positions of the positioning rods, and then placing the filter net on the top of the mounting plate and pressing the positioning rods with the overpressure plate, the filter net will not come off the positioning rods, which facilitates the installation and replacement of the filter net and is more convenient to use.

[0005] Aiming at the above problems, although the solution given by the existing patent has the function of pressing the positioning rods with the overpressure plate so that the filter net will not come off the positioning rods, facilitating the installation and replacement of the filter net, it cannot perform multiple filtrations on the raw materials during use, resulting in poor processing effect of the raw materials and low raw material quality.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0026] The present invention provides a technical solution:

[0027] Please refer to Figures 1 to 4, An extrusion device for a filtering equipment used in the production of silkworm pupa protein peptides, comprising a device housing 1. A pressing member 2 is fixed on the upper surface of the device housing 1. A circulating mechanism for circulating and filtering the raw materials is connected to the outer surface of the device housing 1. An extrusion mechanism for filtering the raw materials is fixed at the upper end of the pressing member 2. A conveying mechanism for conveying the raw materials is installed on the outer wall of the device housing 1;

[0028] The circulating mechanism includes a filter pipe 3. The filter pipe 3 is communicated with the outer surface of the device housing 1. The end of the filter pipe 3 is communicated with a circulating pump 31. The output end of the circulating pump 31 is communicated with a circulating pipe 32 that is mutually communicated with the device housing 1. A filter screen 33 is fixed inside the filter pipe 3. A filter plate 5 is fixed inside the device housing 1. The extrusion mechanism includes a driving motor 4. The driving motor 4 is fixed to the upper end of the pressing member 2 by bolts. A lead screw 41 is fixed to the power output shaft of the driving motor 4. A threaded pipe 42 is threadedly connected to the outer surface of the lead screw 41. The lower end of the threaded pipe 42 penetrates through the device housing 1 and is fixed with an extrusion plate 43. A sealing ring 44 that is closely attached to the inner wall of the device housing 1 is sleeved on the outer surface of the extrusion plate 43. A limiting plate 45 is fixed to the upper end of the threaded pipe 42. Two guide rods 46 that are fixed to the inner wall of the pressing member 2 penetrate through the inside of the limiting plate 45.

[0029] By adopting the above technical solution, before using the extrusion device of the filtering equipment for the production of silkworm pupa protein peptides, first place the device housing 1 in a suitable position. The driving motor 4 on the pressing member 2 drives the lead screw 41 to rotate. Due to the limiting plate 45 fixed on the threaded pipe 42, with the cooperation of the guide rods 46, the rotation of the lead screw 41 drives the threaded pipe 42 connected by threads to move vertically, and then drives the extrusion plate 43 inside the device housing 1 to move. And through the sealing ring 44 provided on the extrusion plate 43, a good sealing effect can be achieved, thereby reducing the occurrence of leakage when the raw materials are extruded. When the raw materials are extruded, the liquid in the raw materials is separated, and the filter plate 5 will block the solids in the raw materials, so that the liquid flows downward through the filter plate 5, thereby filtering the raw materials. After the filtering is completed, the driving motor 4 reversely drives the lead screw 41 to rotate, driving the extrusion plate 43 to reset. When the raw materials need to be filtered again, the circulating pump 31 is started to pump out the liquid. When the liquid passes through the filter screen 33 inside the filter pipe 3, smaller impurities in the liquid can be filtered, and then sent into the device housing 1 through the circulating pipe 32 for circulating filtration and extrusion.

[0030] Specifically, as Figures 1 - 2 shown, the conveying mechanism includes a mounting plate 6. The mounting plate 6 is fixed to the outer wall of the device housing 1. A conveying pump 61 is fixed to the upper surface of the mounting plate 6 by bolts. The output end of the conveying pump 61 is communicated with a conveying pipe 62 that is mutually communicated with the device housing 1. The lower end of the outer wall of the device housing 1 is communicated with a discharge pipe 7. A protective door 8 is hinged to the outer surface of the device housing 1.

[0031] By adopting the above technical solution, the input end of the transfer pump 61 on the mounting plate 6 is connected to an external raw material pipeline. The transfer pump 61 pumps in the raw materials, and through the transfer pipe 62, the raw materials are sent into the device housing 1. By opening the valve on the discharge pipe 7, the processed raw materials are discharged to the outside for collection. By opening the protective door 8, the solids blocked on the filter plate 5 can be cleaned, which is convenient for use.

[0032] Working principle: The input end of the transfer pump 61 on the mounting plate 6 is connected to an external raw material pipeline. The transfer pump 61 pumps in the raw materials, and through the transfer pipe 62, the raw materials are sent into the device housing 1. After the raw material transfer is completed, the drive motor 4 on the extrusion member 2 drives the lead screw 41 to rotate. Due to the limit plate 45 fixed on the threaded pipe 42 and in cooperation with the guide rod 46, the rotation of the lead screw 41 drives the threaded pipe 42 connected by threads to move vertically, thereby driving the extrusion plate 43 inside the device housing 1 to move. And through the sealing ring 44 provided on the extrusion plate 43, a good sealing effect can be achieved, thereby reducing the occurrence of leakage when the raw materials are extruded. When the raw materials are extruded, the liquid in the raw materials is separated, and the filter plate 5 blocks the solids in the raw materials, allowing the liquid to flow downward through the filter plate 5, thereby filtering the raw materials. After the filtering is completed, the drive motor 4 drives the lead screw 41 to rotate in the reverse direction, driving the extrusion plate 43 to reset. When the raw materials need to be filtered again, the circulation pump 31 is started to pump out the liquid. When the liquid passes through the filter screen 33 inside the filter pipe 3, smaller impurities in the liquid can be filtered, and then through the circulation pipe 32, it is sent into the device housing 1 for cyclic filtration and extrusion. By opening the valve on the discharge pipe 7, the processed raw materials are discharged to the outside for collection. By opening the protective door 8, the solids blocked on the filter plate 5 are cleaned.

[0033] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
