Description
Technical Field

[0002] The spiral filter centrifuge is a solid-liquid separation equipment that combines centrifugal force and transfer principles. When in use, it forces solid particles to move toward the outer wall of the centrifuge under the action of centrifugal force through high-speed rotation. Then, due to the difference in sedimentation rates between solid particles and liquid substances, the spiral blades can push the settled solid particles to move toward the discharge port of the centrifuge, thereby reducing the probability of blockage events through the self-discharge of materials.

[0017] Working principle: When in use, the differential assembly is driven by the driving motor to rotate, and then the connecting seat and the baffle can rotate at the same time through the differential assembly. The connecting seat rotates at a relatively high speed, while the baffle rotates at a relatively low speed. When the connecting seat and the baffle rotate at a uniform speed, the solid-liquid mixture is injected into the drum through the feed pipe. At this time, the connecting seat is connected to the turntable, and centrifugal force can be applied to the solid-liquid mixture in contact with it under the support of the evenly distributed fixed plates, so that the solid particles can quickly settle along the inclined surface inside the drum under the cooperation of gravity, and further leave the drum through the evenly distributed through slots, and are The baffle plate and the spiral blade driven by the drum can move toward the rear of the barrel body. When the solid particles pass through the evenly distributed through grooves on the baffle plate surface, they can contact the evenly distributed slide plates. Then, when the slide plates rotate with the baffle ring, the centrifugal force can be used to keep each slide plate in contact with the inner wall of the barrel body. At this time, the solid particles can be pushed by the slide plates and move up along the inner wall of the barrel body until the slide plates rotate to the area where the through opening is located. The solid particles can slide along the slide plates into the extrusion chamber under the action of centrifugal force, and as the slide plates contact the upper arc surface of the T-shaped plate, the T-shaped plate can move toward the inside of the extrusion chamber along the cross plate under the push of the slide plates. At this time, The solid particles inside the extrusion bin can be squeezed by the T-shaped plate, so that part of the liquid material sucked in can re-enter the barrel through the orifice plate, preventing the liquid material from being wasted directly with the solid particles. As the slide plates continuously send the solid particles into the extrusion bin, when the solid particles above the cross plate reach a certain amount, as the slide plate separates from the T-shaped plate again, and the T-shaped plate is moved away from the cross plate by the spring, the solid particles can exert a thrust on the baffle plate to make the baffle plate rotate downward to overcome the resistance exerted by the rotating plate and the slider. As the solid particles pass through the gap after the baffle plate rotates and the discharge port reserved at the bottom of the extrusion bin, When the slide plate contacts the T-shaped plate again, the T-shaped plate can push the slider, the rotating plate and the baffle plate back to the initial position, so as to prepare for the subsequent extrusion of solid particles. In addition, when the solid particles are moved backward by the spiral blades, most of the liquid substances can flow to the front area of the drum through the orifice plate 2, and the evenly distributed arc plates can increase the scouring force of the liquid on the surface of the orifice plate 2 to prevent the solid particles from adhering to the surface of the orifice plate 2. After the liquid passes through the orifice plate 2 and the evenly distributed drainage holes on the surface of the disc, it can be discharged from the corresponding pipe at the front of the barrel body to achieve the purpose of continuous automatic separation.
[0018] The present invention provides a continuous automatic separation type spiral filtering centrifuge. It has the following beneficial effects:
[0019] 1. The present invention can discharge solid and liquid from the front and rear sides respectively through the separation mechanism, and then cooperate with the extrusion mechanism to apply pressure to the collected solid particles in batches to squeeze out the liquid substances contained in them, so as to prevent the liquid substances from being wasted when discharged with the solid particles, and the squeezed solid particles can be actively discharged after gathering to a certain amount, so as to maintain the continuous operation of the separation operation.
[0020] 2. The present invention can utilize centrifugal force and the flushing force of the liquid to clean the two surfaces of the orifice plate by itself through the liquid discharge mechanism, and can prevent solid particles from gathering in large quantities on the two surfaces of the orifice plate in conjunction with the internal contour of the drum, thereby ensuring stable discharge of liquid substances and reducing the probability of blockage by solid particles.

DETAILED DESCRIPTION
[0029] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.
[0030] Please see attached Figure 1 , Attachment Figure 3 , Attachment Figure 5 and attached Figure 7 The embodiment of the present invention provides a continuous automatic separation spiral filtering centrifuge, comprising a base 1, a driving motor 2 is fixedly connected to the rear of the top of the base 1, the output end of the driving motor 2 passes through a barrel 3 and is provided with a separation mechanism 4, a squeezing mechanism 5 is provided at the rear of the barrel 3, and a liquid discharge mechanism 6 is provided at the front of the barrel 3;
[0031] The separation mechanism 4 includes a differential assembly 401, the rear end of the differential assembly 401 is fixedly connected to the rear end of the barrel body 3, the output end of the drive motor 2 is arranged at the rear end of the differential assembly 401, and the front end of the differential assembly 401 is respectively provided with a connecting seat 402 and a baffle 403, the outer rear part of the connecting seat 402 is rotatably connected to the inner side of the baffle 403, the outer front part of the connecting seat 402 is rotatably connected to the drum 404, a feed pipe 405 is arranged in the middle part of the drum 404, the front end of the feed pipe 405 passes through the barrel body 3, a plurality of through grooves 1 406 are arranged in the rear part of the drum 404, a spiral blade 407 is fixedly connected to the front end of the baffle 403, and a plurality of through grooves 2 408 are opened on the outer side of the baffle 403.
[0032] The barrel body 3 can accommodate the separation mechanism 4, the extrusion mechanism 5, and the drainage mechanism 6, and then the differential assembly 401 can be used to make the connecting seat 402 and the baffle plate 403 rotate at different speeds, wherein the connecting seat 402 can generate a large centrifugal force when rotating at a high speed, so that the solid-liquid mixture entering the drum 404 from the feed pipe 405 is thrown to the inner wall of the drum 404, wherein the sedimentation rate of the solid particles is faster, so the solid particles can enter the barrel body 3 from the drum 404 through the evenly distributed through grooves 1 406, and the spiral blades 407 connected to the baffle plate 403 can be driven by the baffle plate 403 to continuously push the solid particles entering the barrel body 3 to the rear part of the barrel body 3, and then enter the rear side of the baffle plate 403 through the evenly distributed through grooves 2 408 on the surface of the baffle plate 403 for subsequent processing, while most of the liquid substances can remain in the drum 404 and flow to the inner front side of the barrel body 3 along the inclined surface of the inner front part of the drum 404, thereby achieving the purpose of continuous separation of solid and liquid.
[0033] Please see attached Figure 4 The inner side of the spiral blade 407 is fixedly connected to the outer side of the rotating drum 404 , the outer side of the spiral blade 407 is rotatably connected to the inner side of the barrel body 3 , and the outer side of the baffle plate 403 is rotatably connected to the rear part of the barrel body 3 .
[0034] The rotating drum 404 and the barrel body 3 can ensure that the spiral blades 407 can effectively push the solid particles to move, and the barrel body 3 can provide support and limit for the connecting seat 402, the baffle plate 403, etc. to prevent horizontal displacement.
[0035] Please see attached Figure 4 and attached Figure 7A turntable 409 is fixedly connected to the front end of the connecting seat 402 , and a plurality of fixing plates 410 are fixedly connected to the outer side of the turntable 409 . The ends of the plurality of fixing plates 410 away from the turntable 409 are all slidably connected to the inside of the rotating drum 404 .
[0036] The turntable 409 can cooperate with the baffle plate 403 to enhance the centrifugal force on the solid-liquid mixture, so that the solid particles can be dispersed more evenly inside the drum 404, avoiding that some areas inside the drum 404 are continuously affected by the solid particles. At the same time, the turntable 409 can be supported by the evenly distributed fixing plates 410 to prevent it from shaking when rotating.
[0037] Please see attached Figure 2 , Attachment Figure 3 , Attachment Figure 5 and attached Figure 6 The extrusion mechanism 5 includes a baffle ring 501, the front end of which is fixedly connected to the outer side of the rear end of the baffle plate 403, and a plurality of slide plates 502 are slidably connected inside the baffle ring 501. A through opening 503 is opened at the rear part of one side of the barrel body 3, and an extrusion bin 504 is fixedly connected to one side of the barrel body 3. A horizontal plate 505 is fixedly connected inside the extrusion bin 504, and a T-shaped plate 506 is slidably connected to the bottom end of the horizontal plate 505. A baffle plate 507 is rotatably connected inside the horizontal plate 505, and a rotating plate 508 is rotatably connected to the bottom end of the baffle plate 507, and a slider 509 is rotatably connected to the bottom end of the rotating plate 508.
[0038] The baffle ring 501 can obtain the rotational force output by the baffle plate 403, so that the slide plates 502 evenly distributed inside thereof can approach the inner wall of the barrel body 3 along the corresponding slide grooves inside the slide plates 502 under the action of centrifugal force. At this time, the solid particles entering the rear area of the baffle plate 403 can rotate with the baffle ring 501 under the action of each slide plate 502, until the slide plate 502 approaches the area where the through port 503 is located, the solid particles can slide toward the extrusion chamber 504 under the action of the centrifugal force, and then the slide plate 502 can move along with the baffle ring 501. The slide plate 502 rotates and contacts the upper arc surface of the T-shaped plate 506, and under the action of centrifugal force, the slide plate 502 can exert a certain thrust on the T-shaped plate 506 to move the T-shaped plate 506 along the transverse plate 505 toward the inside of the extrusion chamber 504. At this time, the solid particles falling into the extrusion chamber 504 can be squeezed to a certain extent under the action of the transverse plate 505 and the T-shaped plate 506, thereby preventing a large amount of liquid substances from being directly wasted after being absorbed by the solid particles and discharged with the solid particles. Under the continuous action of the slide plate 502, the transverse plate 50 The solid particles on the top of the slide plate 502 may gather to a certain amount. When the slide plate 502 separates from the T-shaped plate 506 again, the T-shaped plate 506 may move away from the horizontal plate 505 under the push of the solid particles. At this time, the baffle plate 507 in the middle of the horizontal plate 505 is no longer supported by the T-shaped plate 506. Therefore, under the action of relatively large pressure, the baffle plate 507 can push the slider 509 through the rotating plate 508 to overcome the friction between it and the extrusion chamber 504 and move toward the direction of the T-shaped plate 506. The baffle plate 507 can It rotates accordingly so that the solid particles can be discharged through the gap left after its movement and the discharge port reserved at the bottom of the extrusion bin 504. As the subsequent slide 502 pushes the T-shaped plate 506 back again, the T-shaped plate 506 can contact the slider 509 and push the slider 509, the rotating plate 508, and the baffle 507 back to the initial position to ensure that the subsequent solid particles can continue to be extruded. The sliding of the slide 502 along the baffle ring 501 can also reduce the rigid impact between it and the T-shaped plate 506 to a certain extent.
[0039] Please see attached Figure 6 A perforated plate 510 is fixedly connected inside the T-shaped plate 506 , and the front and rear sides of the T-shaped plate 506 are slidably connected to the front and rear sides of the extrusion chamber 504 , respectively, and the through opening 503 faces the extrusion chamber 504 .
[0040] Through the orifice plate 1 510 , the liquid material squeezed out of the solid particles can leave the squeezing chamber 504 and flow back into the barrel body 3 , and the through port 503 faces the squeezing chamber 504 to ensure that the solid particles enter the squeezing chamber 504 from the barrel body 3 .
[0041] Please see attached Figure 6 The front and rear sides of the closed end inside the extrusion chamber 504 are fixedly connected with springs 511, and the front and rear side springs 511 are fixedly connected to the lower part of one side of the T-shaped plate 506 close to the retaining ring 501, and the bottom end of the slider 509 is slidably connected to the bottom end inside the extrusion chamber 504.
[0042] The spring 511 can push the T-shaped plate 506 to move toward the barrel body 3 when there are fewer solid particles inside the extrusion bin 504, so as to prevent the T-shaped plate 506 from staying inside the extrusion bin 504 and being unable to continue to receive other solid particles. The extrusion bin 504 can be used to guide the movement direction of the slider 509. In addition, the slider 509 is relatively heavy to ensure that it has sufficient friction in the contact area with the extrusion bin 504.
[0043] Please see attached Figure 3 and attached Figure 6 The rear end of the retaining ring 501 is rotatably connected to the rear end of the barrel body 3 , and the retaining ring 501 is located outside the differential assembly 401 .
[0044] The retaining ring 501 can cooperate with the corresponding sealing ring to shield the differential assembly 401 to prevent it from contacting with liquid substances.
[0045] Please see attached Figure 3 , Attachment Figure 4 and attached Figure 7 The discharge mechanism 6 includes a second orifice plate 601, the outer side of the second orifice plate 601 is fixedly connected to the inside of the drum 404, a plurality of arc plates 602 are fixedly connected to the rear end of the second orifice plate 601, a disc 603 is fixedly connected to the front end of the drum 404, and a plurality of discharge holes 604 are opened inside the disc 603.
[0046] The internal inclined surface of the drum 404 can prevent a large number of solid particles from gathering in the area where the orifice plate 601 is located, and the orifice plate 601 can prevent solid particles from entering the front part of the drum 404 from the rear part. At the same time, the evenly distributed arc plates 602 can enhance the scouring of the surface of the orifice plate 601 by the liquid when the orifice plate 601 rotates with the drum 404, thereby reducing the probability of solid particles adhering to the surface of the orifice plate 601. In addition, the disc 603 and the evenly distributed drainage holes 604 can cooperate with the drum 404 to further filter substances with a certain sedimentation property, thereby ensuring that the liquid substances separated and discharged from the front area of the drum 404 meet the composite requirements.
[0047] Please see attached Figure 4 The outer side of the disc 603 is fixedly connected with a hole plate 3 605, and the outer side of the hole plate 3 605 is rotatably connected to the front part of the barrel body 3.
[0048] The front of the drum 404 can be supported by the orifice plate 3 605 and the barrel body 3 . At the same time, the orifice plate 3 605 can also be used to separate and collect liquid substances that move to the outside of the drum 404 along with the solid particles to a certain extent.
[0049] Please see attached Figure 1The front and rear parts of the outer side of the barrel body 3 are fixedly connected with fixing frames 7, the bottom ends of the front and rear fixing frames 7 are fixedly connected to the top of the base 1, and the upper front end of the barrel body 3 is fixedly connected with a transparent observation window 8.
[0050] The barrel body 3 can be fixed by the fixing frame 7, so that the driving motor 2 can stably drive the moving parts inside the barrel body 3, and the transparent observation window 8 is used to facilitate observation of the separation situation inside the barrel body 3.
[0051] 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.
