DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] As attached Figures 1 to 4 The centrifuge drum discharge mechanism shown includes a centrifuge body 1, a bubble elimination assembly 4, and a rotating shaft 6. A feed inlet 2 is provided on the left side of the upper end surface of the centrifuge body 1. The bubble elimination assembly 4 is disposed in the inner cavity of the centrifuge body 1. The rotating shafts 6 are respectively disposed on both sides of the centrifuge body 1. Fixed piles 5 are disposed on both sides of two sets of rotating shafts 6. A second motor 7 is disposed at the center of one side of one set of fixed piles 5.

[0025] The bubble elimination component 4 includes a drum mechanism 401, which is arranged in the inner cavity of the centrifuge body 1. A microporous filter 402 is provided on the outer surface of the drum mechanism 401, and a transmission rod 403 is provided at the center of the inner cavity of the drum mechanism 401. The lower end of the transmission rod 403 is connected to a first motor 404.

[0026] When the device starts to work, the material is put into the drum mechanism 401 in the centrifuge body 1 through the feeding port 2, and then the drum mechanism 401 is driven to rotate by the second motor 7. When the drum mechanism 401 rotates at high speed, the centrifugal force pushes the solid particles in the mixture outward, so that the solid particles are deposited on the inner wall of the drum mechanism 401. The microporous filter screen 402 can effectively separate the liquid and the solid particles, so that the solid particles are effectively retained under the action of the centrifugal force, and the liquid can flow out freely. When the centrifuge body 1 is working, the two groups of rotating shafts 6 are movably installed between the two groups of fixed piles 5. When shaking is needed, the centrifuge body 1 can be shaken back and forth by driving one group of rotating shafts 6 by the second motor 7, so as to realize the shaking function. The liquid and the solid particles separated by the centrifugal force can be more uniformly shaken, so as to prevent deposition and avoid stratification. Then, the foam generated in the centrifugal process due to strong rotation is effectively filtered by the microporous filter screen 402 before flowing out, so as to ensure that the flowing liquid does not contain excess gas or foam.

[0027] Example 2

[0028] Based on the embodiment 1, the scheme in the embodiment 1 is further refined based on the following specific working modes, as shown in the following: Figures 1 to 4 The details are described below.

[0029] As a preferred embodiment, the outer surface of the upper end of the feeding port 2 is provided with a sealing cover 3, and the feeding port 2 is threadedly connected with the sealing cover 3. Further, the sealing cover 3 is threadedly connected with the feeding port 2. Only the sealing cover 3 is rotated along the thread to rotate out, so as to open or seal the feeding port 2.

[0030] As a preferred embodiment, the left side of the lower end of the centrifuge body 1 is provided with a liquid discharge pipe 9, and the center of the liquid discharge pipe 9 is provided with an electric valve 10. The bottom of the inner cavity of the centrifuge body 1 is inclined to the liquid discharge pipe 9. Further, the liquid discharged by the high-speed rotation of the drum mechanism 401 flows along the inner wall of the centrifuge body 1 to the bottom, and then flows to the liquid discharge pipe 9 through the inclined bottom surface in the centrifuge body 1, and is discharged by automatically opening the electric valve 10.

[0031] As a preferred embodiment, the transmission rod 403 penetrates the drum mechanism 401 and the lower end surface of the centrifuge body 1 in sequence, and the output end of the first motor 404 is connected with the transmission rod 403. The surface of the microporous filter screen 402 is provided with a plurality of micropores. Further, the first motor 404 drives the first motor 404 to rotate, so as to drive the drum mechanism 401 to rotate at the same time, generate centrifugal force, and then filter the solid-liquid and gas-foam through the microporous filter screen 402.

[0032] As a preferred embodiment, the output end of the second motor 7 is connected to one of the groups of rotating shafts 6 by passing through one of the groups of fixed piles 5, the two groups of fixed piles 5 correspond to each other in a mirror manner, and the lower end of the fixed piles 5 is installed with a load-bearing seat 8; further, the two groups of fixed piles 5 correspond to each other and are connected to the centrifuge body 1 through two groups of rotating shafts 6, and then one of the groups of rotating shafts 6 drives the centrifuge body 1 to swing back and forth through the rotational force driven by the second motor 7 to achieve the shaking function.

[0033] As a preferred embodiment, a group of spaces are formed between the centrifuge body 1 and the drum mechanism 401, and the microporous filter 402 is installed around the outer surface of the drum mechanism 401; further, the space formed by the centrifuge body 1 and the drum mechanism 401 is used for the flow and discharge of liquid, and the microporous filter 402 comprehensively filters the liquid thrown out by the drum mechanism 401.

[0034] The working process of the present invention is as follows: when the device starts to work, the material is put into the drum mechanism 401 inside the centrifuge body 1 through the feed port 2, and then the sealing cover 3 only needs to be rotated along the thread to seal the feed port 2, and then the first motor 404 drives the transmission rod 403 to rotate, thereby driving the drum mechanism 401 to rotate. When the drum mechanism 401 rotates at high speed, the centrifugal force will cause the solid particles in the mixture to be pushed outward, thereby pushing the solid to be deposited on the inner wall of the drum mechanism 401. The microporous filter 402 can effectively separate the liquid and solid particles, ensuring that the solid matter is effectively retained under the action of centrifugal force, while the liquid can flow out freely. When the centrifuge body 1 is performing centrifugal work, it is movably installed between the two groups of fixed piles 5 through two groups of rotating shafts 6. When it needs to be shaken and swung, the two groups of fixed piles 5 correspond to each other, and the bottom increases the contact area through the load-bearing seat 8. , connected to the centrifuge body 1 through two sets of rotating shafts 6, and then one set of rotating shafts 6 drives the centrifuge body 1 to swing back and forth to achieve the shaking function. It is only necessary to drive one set of rotating shafts 6 through the second motor 7 to drive the centrifuge body 1 to swing back and forth to achieve the shaking function, so that the liquid and the solid particulate matter separated by centrifugal force can be shaken more evenly to prevent sedimentation. Then, the foam generated by the strong rotation during the centrifugal process before outflow is effectively filtered through the microporous filter 402 to ensure that the outflowing liquid does not contain excess gas or foam. Then, the liquid thrown out by the high-speed rotation of the drum mechanism 401 flows to the bottom along the inner wall of the centrifuge body 1, and then flows to the drain pipe 9 through the inclined bottom surface inside the centrifuge body 1, and is automatically opened and discharged by controlling the electric valve 10. The above is the working principle of this centrifuge drum discharge mechanism.

[0035] Finally: the above described is only the preferred embodiment of the utility model, and does not limit the utility model, and any modification, equivalent replacement, improvement etc. that is made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
