Description

Technical Field

[0001] This invention belongs to the field of microbial culture technology, specifically relating to a recyclable biological fermentation broth filtration and separation device. Background Technology

[0002] Microbial inoculants are live bacterial preparations made by industrially producing and propagating target microorganisms (effective bacteria) and then using porous materials as adsorbents (such as peat moss and vermiculite) to adsorb the fermentation broth containing the bacteria. These inoculants are used for seed dressing or root dipping and have the effects of directly or indirectly improving soil, restoring soil fertility, preventing soil-borne diseases, maintaining the balance of rhizosphere microbial flora, and degrading toxic substances. The proper use of agricultural microbial inoculants can increase agricultural yield, improve agricultural product quality, reduce fertilizer use, reduce costs, improve soil, and protect the ecological environment. After the fermentation of microbial inoculants is completed, the fermentation broth contains a large number of bacteria and solid substrates, so it is necessary to use appropriate filtration and separation equipment to separate the solid and liquid components.

[0003] In existing technologies, the filter components inside the filtration and separation device are mostly fixed inside the equipment, making them difficult to clean. As a result, the filter components become clogged after repeated use, making it difficult to continue filtration. This leads to a low number of cycles and a short lifespan for existing filtration and separation devices. Furthermore, existing filtration devices mostly rely on the natural flow of the solution for filtration, which takes a long time and is inefficient. Utility Model Content

[0004] The purpose of this invention is to provide a recyclable biological fermentation broth filtration and separation device that allows for the disassembly and cleaning of the filter screen to maintain its good permeability, effectively increasing the number of cycles and extending the overall service life of the device. At the same time, the rapid rotation of the filter cylinder quickly discharges the solution, effectively improving the filtration efficiency.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A recyclable biological fermentation broth filtration and separation device includes a collection cylinder, the upper end of which is threadedly connected to a threaded cover plate. The middle part of the threaded cover plate is rotatably connected to an injection pipe via a sealed bearing. The bottom surface of the threaded cover plate is fixedly connected to the upper end of a pressure ring. The bottom end of the pressure ring contacts the upper end of a filtration mechanism. The filtration mechanism is disposed inside the collection cylinder. The middle part of the bottom end of the collection cylinder is fixedly connected to the upper end of a drain pipe.

[0007] Furthermore, a drain valve is provided inside the drain pipe, and the bottom of the outer side of the liquid collecting cylinder is simultaneously fixedly connected to the upper ends of multiple support legs.

[0008] Furthermore, the filtration mechanism includes a filter cylinder, the upper end of the outer side of the filter cylinder being rotatably connected to the inner side of a fixing ring via a bearing, and the outer side of the fixing ring being fixedly connected to the upper ends of multiple insert plates.

[0009] Furthermore, the bottom ends of the plurality of insert plates are respectively inserted into a plurality of slots, and the plurality of slots are all opened on the upper surface of the support ring, and the outer side of the support ring is fixedly connected to the inner wall of the liquid collecting cylinder.

[0010] Furthermore, the upper end of the outer side of the filter cartridge is fixedly connected to the inner side of the external gear ring, and the external gear ring is meshed with a gear.

[0011] Furthermore, the gear is fixedly mounted on the motor output shaft, and the motor is fixedly connected to the retaining ring via a mounting base.

[0012] Furthermore, the upper surfaces of the two insert plates on the front and rear sides are fixedly connected to the front and rear sides of the bottom end of the limiting frame, and the upper surface of the limiting frame overlaps with the bottom surface of the pressure ring.

[0013] Furthermore, the bottom end of the filter cylinder is threadedly connected to a threaded plug plate, and multiple through grooves are provided inside the cylinder wall of the filter cylinder.

[0014] Furthermore, the bottom end of each of the through slots is connected to the bottom surface of the filter cylinder, and a filter screen is fitted inside each of the through slots. The two vertical end faces of each filter screen are fixedly connected to the opposite ends of the two connecting plates, respectively.

[0015] Furthermore, the opposite ends of the two connecting plates are respectively inserted into the two connecting slots, which are respectively opened at both ends of the through groove. Each connecting slot is fixedly provided with a sealing gasket that fits tightly against the connecting plate. The bottom end of each connecting plate and the filter screen is in contact with the bottom end of the threaded plug plate.

[0016] The technical effects achieved by this utility model are as follows:

[0017] This invention mounts the filter cylinder onto a support ring by setting a fixing ring, insert plate, and slot. The filter cylinder wall has a through groove and a connecting groove that connects to the filter screen and connecting plate. After filtering the bio-fermentation broth using this device, the filter cylinder can be removed from the collection cylinder, and the connecting plate and filter screen can be removed from the connecting groove and through groove respectively. This facilitates cleaning of the filter screen, ensuring good permeability, increasing the number of times the filter screen can be reused, and extending the overall service life of the device.

[0018] This invention connects the motor and the filter cylinder by setting an external gear ring and gears. After the solution to be filtered is added to the filter cylinder through the injection pipe, the motor, gears, and external gear ring can drive the filter cylinder to rotate rapidly. The centrifugal force generated when the filter cylinder rotates will throw the fermentation liquid through the filter screen and into the collection cylinder, so that impurities are retained on the inside of the filter screen, thereby effectively shortening the filtration time and improving the filtration efficiency.

[0026] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0027] like Figure 1-5As shown, a recyclable biological fermentation broth filtration and separation device includes a collection cylinder 1. The upper end of the collection cylinder 1 is threadedly connected to a threaded cover plate 4. The middle part of the threaded cover plate 4 is rotatably connected to an injection pipe 5 through a sealed bearing. The bottom surface of the threaded cover plate 4 is fixedly connected to the upper end of a pressure ring 7. The bottom end of the pressure ring 7 contacts the upper end of a filter mechanism 6. The filter mechanism 6 is located inside the collection cylinder 1. The middle part of the bottom end of the collection cylinder 1 is fixedly connected to the upper end of a drain pipe 3. By providing a pressure ring 7 at the bottom of the threaded cover plate 4, after connecting the threaded cover plate 4 to the upper end of the collection cylinder 1, the bottom end of the pressure ring 7 can contact the upper surface of a limiting frame 611. Thus, the pressure ring 7 and the threaded cover plate 4 restrict the vertical movement of the filter cylinder 61, effectively improving the stability of the filter cylinder 61 during rotation.

[0028] A drain valve is installed inside the drain pipe 3, and the bottom of the outer side of the collection cylinder 1 is simultaneously fixedly connected to the upper ends of multiple support legs 2.

[0029] The filter mechanism 6 includes a filter cylinder 61. The upper end of the outer side of the filter cylinder 61 is rotatably connected to the inner side of the fixing ring 66 via a bearing. The outer side of the fixing ring 66 is also fixedly connected to the upper end of a plurality of insert plates 613.

[0030] The bottom ends of multiple insert plates 613 are respectively inserted into multiple slots 64. Multiple slots 64 are all opened on the upper surface of the support ring 65. The outer side of the support ring 65 is fixedly connected to the inner wall of the liquid collecting cylinder 1. By opening slots 64 on the support ring 65 and setting insert plates 613 on the fixing ring 66 to be inserted into slots 64, the filter cylinder 61 is supported and fixed by the insertion of insert plates 613 and slots 64, and the filter cylinder 61 is also easy to be quickly disassembled and assembled.

[0031] The upper end of the outer side of the filter cartridge 61 is fixedly connected to the inner side of the external gear ring 69, and the external gear ring 69 is meshed with the gear 68.

[0032] Gear 68 is fixedly mounted on the output shaft of motor 67. Motor 67 is fixedly connected to fixed ring 66 via mounting base. After the solution to be filtered is added to filter cylinder 61 through injection pipe 5, motor 67, gear 68 and external gear ring 69 can drive filter cylinder 61 to rotate rapidly. The centrifugal force generated when filter cylinder 61 rotates will throw the fermentation liquid through filter screen 63 into collection cylinder 1, so that impurities are retained on the inside of filter screen 63, thereby effectively shortening filtration time and improving filtration efficiency.

[0033] The upper surfaces of the two insert plates 613 on the front and rear sides are fixedly connected to the bottom front and rear sides of the limit frame 611, respectively, and the upper surface of the limit frame 611 overlaps with the bottom surface of the pressure ring 7.

[0034] The bottom end of the filter cylinder 61 is threadedly connected to the threaded plug plate 62. Multiple through grooves 610 are provided inside the cylinder wall of the filter cylinder 61. By providing the threaded plug plate 62 at the bottom end of the filter cylinder 61, the threaded plug plate 62 is used to limit and fix the connecting plate 614 and the filter screen 63, and it is also convenient to disassemble and assemble the filter screen 63.

[0035] The bottom end of each through groove 610 is connected to the bottom surface of the filter cylinder 61. Each through groove 610 is fitted with a filter screen 63. The two vertical end faces of each filter screen 63 are fixedly connected to the opposite ends of the two connecting plates 614 respectively.

[0036] The opposite ends of the two connecting plates 614 are respectively inserted into the two connecting grooves 612. The two connecting grooves 612 are respectively opened at both ends of the through groove 610. Each connecting groove 612 is fixedly provided with a sealing gasket that fits tightly against the connecting plate 614. The bottom end of each connecting plate 614 and the filter screen 63 is in contact with the bottom end of the threaded plug plate 62.

[0037] The working principle of this utility model is as follows: When using this device to filter and separate biological fermentation liquid, the user can connect the injection pipe 5 to the outlet pipe of the fermentation device, and inject the biological fermentation liquid into the filter cylinder 61 through the injection pipe 5. At the same time, the motor 67 is controlled to work. When the motor 67 works, it drives the filter cylinder 61 to rotate rapidly through the gear 68 and the external gear ring 69. At this time, the centrifugal force generated by the rotation of the filter cylinder 61 throws the fermentation liquid out through the filter screen 63, so that the fermentation liquid flows into the collection cylinder 1. The impurities in the fermentation liquid are left on the inside of the filter screen 63. During filtration, the drain valve can be opened so that the solution in the collection cylinder 1 is discharged through the drain pipe 3.

[0038] After filtration is complete, the user can rotate the threaded cover 4 to remove it from the top of the collection cylinder 1. At this time, the user can pull the filter cylinder 61 upward to disengage the insert plate 613 from the slot 64 and remove the filter cylinder 61 from the collection cylinder 1. Then, rotate the threaded plug 62 to separate the threaded plug 62 from the filter cylinder 61. At this time, pull the filter screen 63 downward to disengage the filter screen 63 from the connecting plate 614 from the through groove 610 and the connecting groove 612 respectively. Then, the filter screen 63 can be cleaned.

[0039] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
