Description

Technical Field

[0001] The invention belongs to the field of centrifugal filtration, and in particular relates to a centrifugal filtration device for fecal bacteria treatment. Background Art

[0002] Fecal microbiota transplantation (FMT) is a method of transplanting functional flora from healthy human feces into the gastrointestinal tract of patients to help them rebuild a normal intestinal flora to treat intestinal and extraintestinal diseases. The extraction of intestinal bacteria from feces needs to be achieved through a filtration device.

[0003] In the traditional process of centrifugal filtration for extracting fecal bacteria, the fecal slurry in the fecal liquid is easily adhered to the inner wall of the centrifuge cylinder during the unidirectional spiral centrifugal rotation in the centrifuge cylinder. Not only is it difficult to clean, but when the fecal slurry adheres to a certain thickness, it may block the narrow conical opening at the bottom of the centrifuge cylinder, thereby affecting the centrifugal filtration effect of the centrifuge cylinder on the fecal liquid when the centrifuge cylinder is started.

[0004] In order to avoid the above technical problems, it is necessary to provide a centrifugal filter device for fecal bacteria treatment to overcome the above defects in the prior art. Summary of the invention

[0005] The object of the present invention is to provide a centrifugal filter device for fecal bacteria treatment to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: a centrifugal filter device for fecal bacteria treatment, comprising a centrifugal cylinder, a dirt collection frame is connected to the bottom of the centrifugal cylinder, a rotating ring frame is rotatably provided on the upper surface of the centrifugal cylinder, a discharge pipe is rotatably provided inside the rotating ring frame, a plurality of sliding rods are slidably provided on the rotating ring frame, a fixed ring block is fixedly connected to the top of each sliding rod, a rotating ring block is rotatably provided on the outside of the fixed ring block, a top ring frame is fixedly provided on the upper surface of the rotating ring frame, and the rotating ring block is threadedly connected to the top ring Inside the frame, a plurality of rotating handles are fixedly provided on the rotating ring block, the bottom ends of the plurality of sliding rods are commonly fixedly connected to a cross-shaped telescopic rod member composed of a plurality of telescopic rods, the inner wall of the centrifugal cylinder is provided with a spiral ring, the plurality of telescopic ends on the cross-shaped telescopic rod member are all fixedly connected to the spiral ring, an extension rod is fixedly connected to the central part of the lower surface of the cross-shaped telescopic rod member, a stop block is fixedly provided at the bottom end of the extension rod, a driving mechanism is provided on the centrifugal cylinder, the driving mechanism is drivingly connected to the top ring frame, and a reversing conveying device is provided on one side of the centrifugal cylinder.

[0007] As a preferred embodiment, a bottom rod is eccentrically fixedly provided at the bottom end of the spiral ring, a shift block is provided on the bottom rod, and the bottom rod and the shift block are not located at the same center of a circle.

[0008] As a preferred embodiment, the driving mechanism includes a driving motor, and the driving motor is connected to the outer surface of the centrifugal cylinder.

[0009] As a preferred embodiment, the output shaft of the driving motor is fixedly connected with a gear, and the outside of the top ring frame is fixedly provided with a gear ring.

[0010] As a preferred embodiment, the gear and the gear ring are meshed with each other.

[0011] As a preferred embodiment, the reversing conveying device comprises a reversing valve body, and one side of the reversing valve body is connected and provided with two feed pipes.

[0012] As a preferred embodiment, the two feed pipes are respectively connected to one side of the centrifugal cylinder, and the two feed pipes are located at different eccentric positions before and after the centrifugal cylinder.

[0013] As a preferred embodiment, the rotating ring frame is respectively provided with a first opening and a second opening, there is a certain distance between the first opening and the second opening, and a feed pipe is connected to one side of the reversing valve body.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The present invention arranges a spiral ring in the centrifugal cylinder. When the top ring frame is driven to rotate, the spiral ring is driven to rotate through the rotating ring frame, the sliding rod and the cross-shaped telescopic rod, so that the spiral ring can scrape the feces slurry on the inner wall of the centrifugal cylinder through rotation. At the same time, the spiral ring can synchronously spirally send the feces slurry scraped off the inner wall of the centrifugal cylinder into the dirt collection frame at the bottom of the centrifugal cylinder through the rotation of the spiral pusher, thereby realizing automatic scraping of the inner wall of the centrifugal cylinder. In this process, the rotating ring block can be rotated by rotating the handle, and the thread downward movement of the rotating ring block in the top ring frame can be achieved through the fixed The fixed ring block drives the sliding rod to move downward, and the sliding rod will press the spiral ring through the cross-shaped telescopic rod, so that the conical spiral ring is pressed against the inner wall of the centrifuge cylinder more tightly, which helps to ensure that the spiral ring rotates in the centrifuge cylinder and is scraped more cleanly. At the same time, when the spiral ring is pressed, the cross-shaped telescopic rod will adapt to the ground expansion and contraction, and the block at the bottom of the extension rod can also move downward to poke through the narrow opening at the bottom of the centrifuge cylinder. In summary, the sticky feces slurry on the inner wall of the centrifuge cylinder can be scraped and cleared, and the material can be dropped smoothly, which helps to ensure the centrifugal filtration effect of the centrifuge cylinder on the fecal liquid.

[0016] The present invention, by providing a reversing valve body, can change the discharge positions of the two feed pipes under the operation of the reversing valve body, so that the feces entering from the feed pipe can realize clockwise and counterclockwise centrifugal rotation to feed liquid. In this process, the rotating ring frame will rotate to connect the feed pipe corresponding to one of the first port and the second port, while the other feed pipe is blocked by the outer wall of the rotating ring frame due to the spacing between the first port and the second port, preventing the feces liquid centrifugally transferred from the rotating ring frame to enter the closed feed pipe, thereby making it possible to flush the rotating ring frame and the inner wall of the centrifuge barrel in different directions through the reversing feeding of the two feed pipes, thereby helping to prevent the feces slurry impurities from sticking to the inner wall of the centrifuge barrel during unidirectional centrifugal rotation.

[0017] The present invention provides a bottom rod and a shifting block. When the spiral ring rotates to perform a spiral scraping, the bottom rod and the shifting block will also rotate synchronously. Since the bottom rod and the shifting block are eccentrically arranged at the bottom of the spiral ring, the shifting block can scrape a larger range when rotating, so that the accumulated materials coming out of the bottom of the centrifugal drum and entering the waste collection frame can be leveled, thereby extending the storage time in the waste collection frame and helping to reduce the number of cycles of cleaning the waste collection frame.

At the same time, the spiral ring 11 can synchronously spirally send the slurry scraped off the inner wall of the centrifugal cylinder 1 into the dirt collection frame 2 at the bottom of the centrifugal cylinder 1 through the spiral pusher rotation, thereby realizing automatic scraping of the inner wall of the centrifugal cylinder 1. In this process, the rotating ring block 7 can be rotated by rotating the handle 9, and the downward movement of the thread of the rotating ring block 7 in the top ring frame 8 can drive the slide bar 5 to move downward through the fixed ring block 6 The slide rod 5 will press the spiral ring 11 through the cross-shaped telescopic rod 10, so that the conical spiral ring 11 is pressed against the inner wall of the centrifuge cylinder 1 more tightly, which helps to ensure that the spiral ring 11 rotates in the centrifuge cylinder 1 and scrapes it more cleanly.

The bottom rod 16 and the block 13 are not located at the same center of a circle. By arranging the bottom rod 16 and the shift block 17, when the spiral ring 11 rotates for spiral scraping, the bottom rod 16 and the shift block 17 will also rotate synchronously. Since the bottom rod 16 and the shift block 17 are eccentrically arranged at the bottom of the spiral ring 11, the shift block 17 can scrape a larger range when rotating, so that the accumulated materials coming out of the bottom of the centrifugal drum 1 and entering the waste collection frame 2 can be leveled, thereby extending the storage time in the waste collection frame 2, which helps to reduce the number of cleaning cycles in the waste collection frame 2.

[0029] like Figure 4 As shown, the present invention provides an embodiment, wherein the driving mechanism 14 includes a driving motor 141 , and the driving motor 141 is connected to the outer surface of the centrifugal cylinder 1 .

[0030] like Figure 1 As shown, the present invention provides an embodiment, the output shaft of the driving motor 141 is fixedly connected with a gear 142, and the outside of the top ring frame 8 is fixedly provided with a gear ring 143.

[0031] like Figure 4 As shown, the present invention provides an embodiment in which the gear 142 and the gear ring 143 mesh with each other.

[0032] like Figure 5 As shown, the present invention provides an embodiment, the reversing conveying device 15 includes a reversing valve body 151, and one side of the reversing valve body 151 is connected and provided with two feeding pipes 152.

[0033] like Figure 6 As shown, the present invention provides an embodiment, wherein two feed pipes 152 are respectively connected to one side of the centrifugal cylinder 1 , and the two feed pipes 152 are located at different eccentric positions before and after the centrifugal cylinder 1 .

[0034] like Figure 4As shown, the present invention provides an embodiment, the rotating ring frame 3 is respectively provided with a first opening 153 and a second opening 154, there is a certain distance between the first opening 153 and the second opening 154, one side of the reversing valve body 151 is connected with a feed pipe 155, by setting the reversing valve body 151, the discharge positions of the two feed pipes 152 can be replaced under the operation of the reversing valve body 151, so that the feces entering from the feed pipe 155 can realize clockwise and counterclockwise centrifugal rotation and liquid inlet, in this process, the rotating ring frame 3 The rotation will allow one of the corresponding feed pipes 152 of the first opening 153 and the second opening 154 to be connected, while the other feed pipe 152 is blocked by the outer wall of the rotating ring frame 3 due to the distance between the first opening 153 and the second opening 154, preventing the manure liquid from being centrifuged in the rotating ring frame 3 from entering the closed feed pipe 152, so that the reversing feeding of the two feed pipes 152 can flush the rotating ring frame 3 and the inner wall of the centrifuge cylinder 1 in different directions, thereby helping to prevent the inner wall of the centrifuge cylinder 1 from sticking to the manure slurry impurities during the unidirectional centrifugal rotation.

[0035] The working principle and use process of the present invention are as follows: first, the gear ring 143 is driven to rotate by the gear 142 under the operation of the driving motor 141, and the gear ring 143 drives the top ring frame 8 to rotate. When the top ring frame 8 is driven to rotate, the spiral ring 11 is driven to rotate by rotating the ring frame 3, the sliding rod 5 and the cross-shaped telescopic rod 10, so that the spiral ring 11 can scrape the feces slurry on the inner wall of the centrifugal cylinder 1 through rotation. At the same time, the spiral ring 11 can synchronously spirally send the feces slurry scraped off the inner wall of the centrifugal cylinder 1 into the dirt collection frame 2 at the bottom of the centrifugal cylinder 1 through the spiral pusher rotation, thereby realizing automatic scraping of the inner wall of the centrifugal cylinder 1. In this process, the handle 9 can be rotated to rotate. The rotating ring block 7 can be driven to move downward by the thread of the rotating ring block 7 in the top ring frame 8, and the sliding rod 5 can be driven downward by the fixed ring block 6. The sliding rod 5 will press the spiral ring 11 through the cross-shaped telescopic rod 10, so that the conical spiral ring 11 can be pressed against the ground more tightly by pressing on the inner wall of the centrifuge cylinder 1, thereby helping to ensure that the spiral ring 11 rotates in the centrifuge cylinder 1 and scrapes it more cleanly. At the same time, when the spiral ring 11 is pressed, the cross-shaped telescopic rod 10 will be adaptively extended and retracted, and the block 13 at the bottom end of the extension rod 12 can also poke through the narrow opening at the bottom of the centrifuge cylinder 1 by moving downward. In summary, the sticky feces slurry on the inner wall of the centrifuge cylinder 1 can be scraped and cleared, and the material can be dropped smoothly. A reversing valve body 151 is provided, and the discharge positions of the two feed pipes 152 can be changed under the operation of the reversing valve body 151, so that the feces entering from the feed pipe 155 can realize clockwise and counterclockwise centrifugal rotation to feed liquid. In this process, the rotating ring frame 3 will rotate to connect the feed pipe 152 corresponding to one of the first opening 153 and the second opening 154, while the other feed pipe 152 is blocked by the outer wall of the rotating ring frame 3 due to the spacing between the first opening 153 and the second opening 154, preventing the centrifugal transfer of feces in the rotating ring frame 3 from entering the closed feed pipe 152, thereby enabling the feeding energy of the reversing of the two feed pipes 152 to be increased. It is possible to flush the rotating ring frame 3 and the inner wall of the centrifugal drum 1 in different directions, thereby helping to prevent the inner wall of the centrifugal drum 1 from sticking to the slurry impurities during the unidirectional centrifugal rotation. By arranging the bottom rod 16 and the shift block 17, when the spiral ring 11 performs a spiral scraping rotation, the bottom rod 16 and the shift block 17 will also rotate synchronously. Since the bottom rod 16 and the shift block 17 are eccentrically arranged at the bottom of the spiral ring 11, the shift block 17 can have a larger scraping range when rotating, thereby allowing the accumulated materials coming out of the bottom of the centrifugal drum 1 and entering the waste collection frame 2 to be leveled, thereby extending the storage time in the waste collection frame 2, and helping to reduce the number of cleaning cycles in the waste collection frame 2.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
