Description

Technical Field

[0001] This invention relates to the field of microbial agent production technology, specifically to a filtration device for preparing a compound microbial agent that induces agarwood formation. Background Technology

[0002] Chinese Patent Publication No. CN116716168B discloses a stable microbial agent production device, relating to the field of microbial agent production technology. The device includes an inner vessel, a dissolved oxygen component, and a filtration component. An outer vessel is fixed to the outside of the inner vessel, and a heating layer is provided on the inner side wall of the outer vessel. A partition is fixed to the lower inside of the inner vessel. The dissolved oxygen component is installed on one side of the partition, and the filtration component is installed between the partitions. The filtration component includes a bushing, a damping shaft, a support plate, a waterproof motor, a motor shaft, a connecting plate, a screen, a spring, and a baffle. The bushing is fixed to one side of the inner wall of the support plate.

[0003] This invention achieves filtration through a filtration assembly. To prevent screen clogging, a spring is used to connect the screen to the support plate. When the screen is impacted, the spring causes the bacterial agent to vibrate and pass through the screen, thereby changing the position of residual impurities after filtration and preventing screen clogging. During the preparation of the bacterial agent, the cultured bacterial solution needs to be centrifuged before filtration. Before filtration using this equipment, it also needs to pass through a centrifuge. The filter used for bacterial agent filtration is at the micron level. However, since the screen only has the effect of preventing clogging under external force, larger particles in the bacterial culture medium will adhere to the surface of the filter during filtration, affecting the filtration speed.

[0004] Chinese Patent Publication No. CN214715722U discloses an extraction and filtration device for the production of bacteriophage preparations, including an installation chamber. The bottom of the installation chamber is provided with a collection chamber, and the bottom of the collection chamber is provided with a discharge valve extending to the outside of the installation chamber. A filter chamber connected to the inside of the collection chamber is provided in the middle of the installation chamber. The filter chamber is provided with a microfiltration membrane, and the top of the microfiltration membrane is uniformly provided with trapezoidal blocks. The top of the installation chamber is provided with a centrifuge chamber extending to the outside, and the bottom of the centrifuge chamber is uniformly provided with through holes.

[0005] This invention uses impact balls to impact the surface of the microfiltration membrane to increase the filtration speed. However, when using this device to filter bacterial agents, centrifugation is still required before filtration, which involves many preparation steps. Summary of the Invention

[0006] Therefore, in view of the above problems, the present invention provides a filtration device for preparing a compound microbial agent to induce agarwood formation, which solves the problem of multiple preparation steps and slow filtration caused by design defects in existing devices.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0008] A filtration device for preparing a compound microbial inoculant to induce resin formation in agarwood includes:

[0009] frame;

[0010] Outer cylinder, which is mounted on the frame;

[0011] Inner cylinder, which is disposed inside the outer cylinder;

[0012] A filter cartridge is disposed inside the inner cylinder, and the filter cartridge and the inner cylinder are spaced apart to form a filtration zone. The side wall of the filter cartridge is provided with a plurality of filter holes.

[0013] A filter screen, wherein the filter screen is disposed within the filtration zone, and the filter screen has an annular cross-section;

[0014] A shovel blade adjustment device is disposed inside the filter cylinder. The shovel blade adjustment device includes a support plate, a plurality of support rods, a plurality of first connecting parts, a rotating rod, a plurality of second connecting parts, a plurality of adjusting rods, and a plurality of shovel blades.

[0015] The support plate is fixedly connected to the bottom of the filter cylinder, the first end of each support rod is fixedly connected to the edge of the support plate, and the second end of each support rod is rotatably connected to the shovel blade through each of the first connecting pieces;

[0016] The rotating rod is located above the support rod. One end of each of the adjusting rods is rotatably connected to the edge of the support rod through each of the second connecting members, and the other end of each adjusting rod is rotatably connected to the shovel blade through each of the second connecting members. Each adjusting rod rotates with the rotating rod, causing each of the shovel blades to flip along the second end of the support rod.

[0017] Furthermore, the inner diameter of the filter screen is the same as the outer diameter of the filter cartridge. When both the filter screen and the filter cartridge are in a dry state, the filter screen can be fitted onto the outside of the filter cartridge from the top downwards.

[0018] Furthermore, the filter cartridge includes a straight section and a flared section. The straight section is connected to the top of the flared section. The outer diameter of the straight section is consistent. The outer diameter of the flared section gradually increases from the top to the bottom. The height of the filter screen is greater than the height of the straight section.

[0019] Furthermore, it also includes a sealing seat, which is disposed inside the outer cylinder, and the inner cylinder is disposed on top of the sealing seat. The outer cylinder has a liquid outlet on its side wall, which is located above the sealing seat.

[0020] Furthermore, it also includes a fixing plate, which is sleeved on the rotating rod. The bottom of the fixing plate is provided with several third connecting members, and the top of each of the shovel blades is rotatably connected to the fixing plate through each of the third connecting members.

[0021] Furthermore, the cross-section of each of the shovel blades is arc-shaped.

[0022] Furthermore, the top of each of the shovel blades is inclined outward.

[0023] Furthermore, each of the shovel blades is provided with a plurality of liquid guiding grooves, which are spaced apart and located on the inner side of each of the shovel blades.

[0024] Furthermore, the height of the inner cylinder is lower than the height of the outer cylinder.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. The culture medium used in the preparation of the compound microbial agent for inducing agarwood formation contains carbon and nitrogen sources, and the filter screen used for filtration has a pore size between 0.2μm and 0.3μm. This invention, through the structural design of the inner cylinder, filter cylinder, and filter screen, can perform filtration simultaneously with the centrifugation step. The filter cylinder provides support for the filter screen. Compared with traditional filtration, it changes the top-down filtration method to an inside-out filtration method. The filter pores on the surface of the filter cylinder not only allow the bacterial solution to contact the filter screen for filtration, but also limit the effective filtration area, avoiding problems such as prolonged filtration time, mid-process blockage, or even product spoilage that may be caused by an excessively large filtration area.

[0027] 2. When the filter screen at a lower height is clogged by larger particles, affecting the filtration effect, the bacterial solution will carry the larger particles upward to the filter screen at a higher height, without affecting the filtration speed. This invention adjusts the shovel blades through a shovel blade adjustment device, so that the edge of the shovel blade contacts the inside of the filter cartridge to scrape away the blockage and restore the filtration capacity. In addition, it makes it easy to lift the filter screen and rotate it relative to the filter cartridge, placing the unused or insufficiently used part of the filter screen at the filter hole setting to improve filtration efficiency.

[0045] The following will describe in detail the implementation of the present invention with reference to specific embodiments, so that the process of how the present invention uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0046] Example 1

[0047] like Figures 1 to 7 As shown, a filtration device for preparing a compound microbial agent to induce agarwood formation includes:

[0048] A frame 1; an outer cylinder 2 mounted on the frame 1; an inner cylinder 3 located inside the outer cylinder 2, with its height lower than that of the outer cylinder 2; a filter cylinder 4 located inside the inner cylinder 3, forming a filtration zone 43 with the inner cylinder 3 at intervals, and having several filter holes 44 on its sidewall; a filter screen 5 located within the filtration zone 43, with an annular cross-section; and a shovel adjustment device 6 located inside the filter cylinder 4, comprising a support plate 61, several support rods 62, several first connecting parts 63, a rotating rod 64, several second connecting parts 65, several adjusting rods 66, and several shovels. Each of the shovel blades 67 has an arc-shaped cross-section. The support plate 61 is fixedly connected to the bottom of the filter cylinder 4. The first end 621 of each of the support rods 62 is fixedly connected to the edge of the support plate 61. The second end 622 of each of the support rods 62 is rotatably connected to the shovel blades 67 through each of the first connecting members 63. The rotating rod 64 is located above the support rods 62. One end of each of the adjusting rods 66 is rotatably connected to the edge of the support rod 62 through each of the second connecting members 65. The other end of each adjusting rod 66 is rotatably connected to the shovel blades 67 through each of the second connecting members 65. Each adjusting rod 66 rotates with the rotating rod 64, causing each of the shovel blades 67 to flip along the second end of the support rod 62.

[0049] To prevent wear between the edge of the shovel 67 and the inner wall of the filter cylinder 4, rubber protection can be provided on the edge of the shovel 4 on the side that contacts the filter cylinder 4. This is a conventional structural adjustment and will not be described in detail here.

[0050] This application does not specify the exact number of the support rod 62, the first connector 63, the second connector 65, the adjusting rod 66, and the shovel 67; the number may be adjusted according to the actual situation.

[0051] The culture medium used in the preparation of the compound microbial agent for inducing agarwood formation contains carbon and nitrogen sources, and the filter screen used for filtration has a pore size between 0.2μm and 0.3μm. Through the structural design of the inner cylinder 3, filter cylinder 4 and filter screen 5, the present invention can perform filtration simultaneously with the centrifugation step. The filter cylinder provides support for the filter screen 5. Compared with the traditional filtration, it changes the top-down filtration method to an inside-out filtration method. The filter holes 44 on the surface of the filter cylinder 4 not only allow the bacterial liquid to contact the filter screen for filtration, but also limit the effective filtration area, avoiding problems such as prolonged filtration time, mid-process blockage, or even product scrapping that may be caused by an excessively large filtration area.

[0052] When the lower filter screen 5 is clogged by larger particles, affecting the filtration effect, the bacterial solution will carry the larger particles upward to the higher filter screen 5, without affecting the filtration speed. The present invention adjusts the shovel 67 by adjusting the shovel 67 so that the edge of the shovel 67 contacts the inside of the filter cylinder 4 to scrape away the blockage and restore the filtration capacity. In addition, it is convenient to lift the filter screen 5 so that it can rotate relative to the filter cylinder 4, and place the unused or insufficiently used part of the filter screen 5 at the filter hole 44 setting position to improve the filtration efficiency.

[0053] The inner diameter of the filter screen 5 is the same as the outer diameter of the filter cylinder 4. When both the filter screen 5 and the filter cylinder 4 are dry, the filter screen 5 can be sleeved on the outside of the filter cylinder 4 from the top downwards. When the filter screen 5 is wet, the filter screen 5 can rotate relative to the filter cylinder 4.

[0054] The filter cartridge 4 includes a straight cylindrical section 41 and a flared section 42. The straight cylindrical section 41 is connected to the top of the flared section 42. The outer diameter of the straight cylindrical section 41 is uniform, and the outer diameter of the flared section 42 gradually increases from the top to the bottom. The height of the filter screen 5 is greater than the height of the straight cylindrical section 41. When both the filter screen 5 and the filter cartridge 4 are dry, the bottom of the filter screen 5 is located at the flared section 41, which provides a sealing effect. After the filter screen 5 is wetted, it expands slightly and fully fits against the outside of the filter cartridge 4.

[0055] It also includes a sealing seat 21, which is disposed inside the outer cylinder 2, and the inner cylinder 3 is disposed on the top of the sealing seat 21. The outer cylinder 2 has a liquid outlet 22 on its side wall, which is located above the sealing seat 21. It also includes a motor 11, which is disposed on one side of the frame 1. The bottom of the inner cylinder 3 passes through the sealing seat 21 and is driven by the motor 11.

[0056] It also includes a fixing plate 68, which is sleeved on the rotating rod 64. The bottom of the fixing plate 68 is provided with several third connecting members (not shown in the figure). The top of each of the shovel blades 67 is rotatably connected to the fixing plate 68 through each of the third connecting members. The fixing plate 68 stabilizes the top of each of the shovel blades 67, making the shovel blades 67 more stable when rotating.

[0057] Among them, the first connector 63, the second connector 64 and the third connector all adopt the form of connecting post 7 and hook 8, which is simple in structure and low in cost.

[0058] Example 2

[0059] like Figure 8As shown, unlike Embodiment 1, each of the shovel blades 67' is provided with a plurality of liquid guiding grooves 671, and the liquid guiding grooves 671 are arranged at intervals and are located on the inner side of each of the shovel blades 67. The arrangement of each liquid guiding groove 671 enables the bacterial liquid to carry larger particles up the liquid guiding groove to the filter screen 5 at a higher height, which facilitates the uniform distribution of particles in the height direction.

[0060] This application does not specify the number of liquid guiding tanks 671, but may adjust them according to actual circumstances;

[0061] In other preferred embodiments, the top of each of the shovel blades 67 can be tilted outward to further ensure the uniform distribution of particles in the height direction.

[0062] Although the invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the invention without departing from the spirit and scope of the invention as defined in the appended claims, all of which shall be within the scope of protection of the invention.
