Description

Technical Field

[0001] The invention relates to the technical field of centrifugal equipment, in particular to a flat plate closed scraper bottom discharge centrifuge. Background Art

[0002] The flat plate closed scraper bottom discharge centrifuge is a solid-liquid separation equipment. When in use, it generally generates centrifugal force through high-speed rotation, so that the solid particles can be deposited on the inner wall of the barrel under the action of centrifugal force, while the liquid can flow outward through the tiny holes on the surface of the barrel. Because the process is a closed operation, it can prevent the leakage or evaporation of harmful substances. Therefore, it is often used in chemical, pharmaceutical, food, environmental protection and other industries.

[0003] After a certain period of use, in order to prevent the solid particles deposited on the inner wall of the barrel from affecting the subsequent separation operation, the barrel rotation speed is usually reduced and the scraper is used to gradually scrape from top to bottom. However, for the solid particles gathered in the holes on the surface of the barrel, the cleaning effect may be relatively poor. In addition, in order to remove some relatively tightly attached solid particles, it is usually necessary to increase the force between the scraper and the barrel wall.

[0017] Working principle: When in use, the servo motor drives the driving wheel to rotate, and then the engagement between the driving wheel and the driven wheel causes the rotating rod to drive the swash plate to rotate at high speed, so as to break up the mixture entering the separation bin from the feed pipe, and then the material can be thrown into the separation bin under the action of centrifugal force. At this time, the solid particles can be intercepted by the separation bin, while the liquid material can pass through the separation bin and fall into the inner barrel, and can be further discharged from the inner barrel through the corresponding pipeline. In addition, as the driving wheel rotates, the gear ring can also drive the evenly distributed U-shaped frame, knocking hammer, vertical plate, etc. to rotate through the rotating drum and connecting ring. At this time, due to the servo The output speed of the servo motor is relatively high, and the centrifugal force is relatively large. Therefore, the vertical plate can overcome the elastic force of the spring and move away from the knocking hammer with the cooperation of the counterweight block, so as to prevent the knocking hammer from colliding with the vertical plate under the action of centrifugal force. On the contrary, as the separation is completed, when the servo motor drives the rotating rod, rotating drum, etc. to rotate at a low speed and prepares to cooperate with the scraper assembly to clean the solid particles on the inner wall of the separation bin, due to the reduction of centrifugal force, the spring can push the vertical plate and the counterweight block close to the knocking hammer, so that the vertical plate can collide with the knocking hammer. At this time, under the guidance of the U-shaped frame, the knocking hammer can approach the direction of the separation bin, and when the knocking hammer After contacting the separation bin, the hammer can approach the vertical plate again under the action of centrifugal force and the thrust generated during collision, so as to achieve the purpose of destroying the overall stability of the solid particles on the inner surface of the separation bin through multiple knocks of the hammer, avoiding the need to increase the degree of compression between the scraper assembly and the separation bin to ensure the cleaning effect. At the same time, with the use of the scraper assembly, the vibration generated by the knocking of the hammer can cause the solid particles in the holes inside the separation bin to shift, so as to make up for the shortcomings of the scraper assembly when scraping, and improve the overall cleaning effect. In addition, since the servo motor and the rotating rod are The rotation speed of the rotating drum is relatively low, so it will not have a significant impact on the overall stability of the centrifuge. In addition, when the driven wheel rotates, the disc one can also drive the evenly distributed rotating plate one, the arc-shaped protrusions, and the rotating plate two to rotate through the transmission rod. At the same time, under the cooperation of centrifugal force and the disc two, the guide ring, and the guide rod, the evenly distributed arc-shaped protrusions can contact each slider, and then push the slider to move outward along the support frame, so as to increase the bottom support area of ​​the centrifuge when it is in use and improve the overall stability. When it is not in use, the evenly distributed sliders can be pushed inward along the support frame to avoid occupying too much space.

[0018] The present invention provides a flat plate closed scraper bottom discharge centrifuge. It has the following beneficial effects:

[0019] 1. The present invention can utilize centrifugal force to continuously knock on the separation bin when separation is completed and the inner wall of the separation bin is ready to be cleaned through the setting of the cleaning mechanism, so as to destroy the stability of the solid particles and the strength of their connection with each other through vibration, thereby avoiding the need for the scraper assembly to fit the surface of the separation bin with a large force to clean the solid particles, reducing the wear between the scraper assembly and the separation bin, and the solid particles in the holes inside the separation bin can also be displaced due to the vibration, thereby cooperating with the scraper assembly to improve the cleaning effect of the solid particles. In addition, during solid-liquid separation, the knocking hammer can be moved away from the separation bin by the centrifugal force to prevent the stability of the centrifuge from being affected by the knocking during high-speed rotation.

[0020] 2. The present invention can actively increase the contact area between the centrifuge and the ground by setting the support mechanism when the centrifuge is in use, thereby lowering the center of gravity of the centrifuge and improving its stability during rotation. After the separation is completed, the slider can be pushed back into the support frame to avoid it occupying too much space. BRIEF DESCRIPTION OF THE DRAWINGS

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 2 , Attachment Figure 3 , Attachment Figure 5 and attached Figure 7 The embodiment of the present invention provides a flat closed scraper bottom discharge centrifuge, comprising an outer barrel 1, a top cover 2 is arranged on the top of the outer barrel 1, a cleaning mechanism 3 is arranged inside the outer barrel 1, and a supporting mechanism 4 is arranged on the bottom of the outer barrel 1;

[0031] The cleaning mechanism 3 includes a servo motor 301, the top of the servo motor 301 is fixedly connected to the front of the bottom end of the outer barrel 1, the output end of the servo motor 301 passes through the outer barrel 1 and is fixedly connected to a driving wheel 302, the rear of the driving wheel 302 is meshed with a driven wheel 303, the top of the driven wheel 303 is fixedly connected to a rotating rod 304, the outer bottom of the rotating rod 304 is rotatably connected to the inner barrel 305, the outer lower part of the rotating rod 304 is rotatably connected to a separation bin 306, the front of the driving wheel 302 is meshed with a toothed ring 307, the toothed ring 307 A rotating drum 308 is fixedly connected to the top, a connecting ring 309 is fixedly connected to the top of the rotating drum 308, a plurality of U-shaped frames 310 are fixedly connected to the connecting ring 309 on the side close to the rotating rod 304, a vertical plate 311 is slidably connected inside the plurality of U-shaped frames 310, a spring 312 is fixedly connected to the middle of the plurality of vertical plates 311 away from the rotating rod 304, a knocking hammer 313 is rotatably connected to the bottom end of the plurality of U-shaped frames 310 on the side close to the rotating rod 304, and a scraper assembly 314 is arranged on the top side inside the top cover 2.

[0032] The servo motor 301 can drive the driving wheel 302, the driven wheel 303, and the rotating rod 304 to rotate at a high speed, so as to break up the solid-liquid mixture entering the separation bin 306 from the feed pipe and throw it into the separation bin 306, wherein the solid particles can be intercepted by the separation bin 306, and the liquid material can pass through the separation bin 306 and fall into the inner barrel 305, and then be discharged through the corresponding pipeline. At the same time, the meshing between the driving wheel 302 and the gear ring 307 allows the rotating drum 308 to be evenly distributed through the connecting ring 309. The U-shaped frame 310 of the cloth rotates, and the vertical plates 311 and the knocking hammers 313 inside each U-shaped frame 310 can move away from the separation chamber 306 under the action of centrifugal force. When the mixture is separated, as the speed output by the servo motor 301 decreases, the spring 312 can push the vertical plates 311 to overcome the centrifugal force and return to the initial position, so that the vertical plates 311 can collide with the knocking hammers 313, and the knocking hammers 313 can overcome the centrifugal force and approach the separation chamber 306, and the knocking hammers 313 can be pressed. After colliding with the separation bin 306, the hammer 313 can be moved back to the vertical plate 311 by the thrust generated by the collision and the centrifugal force. In summary, the hammer 313 can continuously strike the separation bin 306 under the action of the spring 312, centrifugal force, etc., so as to achieve the purpose of destroying the overall stability of the solid particles on the inner wall of the separation bin 306 through the vibration generated by the striking. At the same time, the vibration can also reduce the adhesion between the solid particles and the separation bin 306, so as to avoid the need for the subsequent scraper assembly 314 to apply a large force to the surface of the separation bin 306 when used, thereby reducing the wear between the separation bin 306 and the scraper assembly 314. As the solid particles on the surface of the separation bin 306 are scraped off by the scraper assembly 314, the solid particles in the holes inside the separation bin 306 can also be displaced by the vibration, and can then be separated from the separation bin 306 to cooperate with the scraper assembly 314 to achieve the purpose of improving the cleaning effect. In addition, the scraped solid particles can be discharged through the corresponding pipe at the bottom of the separation bin 306 along with the cleaning liquid.

[0034] The driving wheel 302, the driven wheel 303 and the gear ring 307 can be limited by the limiting ring 1 315, the limiting ring 2 316 and the limiting ring 317 respectively to ensure that they will not be displaced, thereby preventing the normal meshing between them from being affected by the misalignment.

[0036] The fixing ring 318 can be used to separate the solid particles and liquid substances separated by the separation bin 306 to prevent them from contacting each other again. At the same time, the fixing ring 318 can improve the connection strength between the separation bin 306 and the inner barrel 305. In addition, the multiple cylindrical supporting feet at the bottom of the inner barrel 305 can avoid the driving wheel 302, the driven wheel 303, and the gear ring 307 while ensuring that the inner barrel 305 and the outer barrel 1 can be effectively connected.

[0046] The transmission rod 401 can drive the disk 1 402 to rotate, and then the evenly distributed rotating plate 1 403, the arc-shaped protrusion 404, and the disk 2 406 can rotate with the cooperation of the disk 2 406. At the same time, under the action of centrifugal force, the rotating plate 1 403 and the disk 2 406 can be deflected to push the arc-shaped protrusion 404 to approach the area where the slider 408 is located, and then the evenly distributed sliders 408 can move outward along the support frame 407 to increase the contact area between the centrifuge and the ground, reduce its overall center of gravity, and achieve the purpose of improving the stability of the centrifuge during rotation. In addition, when the centrifuge is not in use, each slider 408 can be pushed into the support frame 407 to avoid it occupying too much space.
