Description

Technical Field

[0001] This utility model relates to the field of water-reducing agent production technology, specifically to a centrifugal device for water-reducing agent production. Background Technology

[0002] Water-reducing agents are concrete admixtures that can reduce the amount of mixing water while maintaining the slump of concrete. When added to concrete mixtures, they disperse cement particles, improve workability, reduce unit water consumption, improve the fluidity of concrete mixtures, or reduce unit cement consumption, thus saving cement. Currently, in the production process of water-reducing agents, it is necessary to perform solid-liquid separation from the suspension containing the substance to extract the water-reducing agent.

[0003] A Chinese patent (publication number CN210543768U) discloses a centrifugal device for the production of water-reducing agents. The centrifuge box is driven to rotate at high speed through the output of a motor via a rotating shaft. Under the centrifugal force generated by the rotation of the centrifuge box and the use of a filter screen, the water-reducing agent raw material is rapidly separated into solid and liquid components. While the operator pulls the sealing cap out of the drain port, the fixed rod, the first vertical rod, and the second vertical rod drive the wall scraper to scrape off the fixed impurities adhering to the inner wall of the centrifuge box, so that the solid matter is discharged from the drain port, thus facilitating the cleaning of the fixed impurities adhering to the inner wall of the centrifuge box.

[0004] However, in the centrifuge device for water-reducing agent production designed above, the wall scraper is located on both sides of the inner wall of the centrifuge box. When it is necessary to remove the impurities adhering to the inner wall, the sealing cover needs to be manually pulled out from the drain port. Then, the fixed rod, the first vertical rod and the second vertical rod are manually pulled out to drive the wall scraper to scrape the fixed impurities adhering to the inner wall of the centrifuge box. This scraping method has low cleaning efficiency and requires manual cleaning by the operator, which increases the operation steps and reduces the overall production efficiency.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution: including an installation box 1, a feed inlet 2 fixedly connected to the top of the installation box 1, and a filter screen bucket 4 disposed inside the installation box 1. A cleaning component is provided on the outside of the filter screen bucket 4. The cleaning component includes a driven gear ring 11 rotatably connected to the top of the inner wall of the installation box 1. An installation rod 13 is fixedly connected to one side of the bottom of the driven gear ring 11. A scraper 14 is fixedly installed on the side of the installation rod 13 away from the filter screen bucket 4. A brush 15 is fixedly installed on the side of the installation rod 13 close to the filter screen bucket 4. The brush 15 abuts against the outside of the filter screen bucket 4. A servo motor 7 is fixedly installed on the top of the installation box 1. A rotating shaft is fixedly connected to the drive end of the servo motor 7. A drive gear 10 is fixedly connected to one end of the rotating shaft. The drive gear 10 meshes with the driven gear ring 11. A drain port 16 is fixedly connected to one side of the bottom of the centrifuge bucket 5.

[0023] In practical implementation, when using the device, the operator injects the water-reducing agent raw material into the filter screen barrel 4 through the feed inlet 2, starts the drive motor 3, and the filter screen barrel 4 and centrifuge barrel 5 rotate inside the mounting box 1. During centrifugation, impurities are thrown to the inner wall of the centrifuge barrel 5 through the filter holes on the outer wall of the filter screen barrel 4. The centrifuged water-reducing agent concentrate can flow out through the discharge port 17. After centrifugation, the drive motor 3 can be turned off to remove the precipitated impurities attached to the inner wall of the centrifuge barrel 5 and the residual impurities on the filter holes of the filter screen barrel 4. The servo motor 7 is then started to drive the drive gear 10 to rotate. When the drive gear 10 rotates, it drives the driven gear that meshes with it. When ring 11 rotates, driven gear ring 11 slides in slide groove 19 through connecting block 12. Mounting rod 13 connected to the bottom of driven gear ring 11 rotates synchronously with driven gear ring 11. Mounting rod 13 is located between filter screen barrel 4 and centrifuge barrel 5. Brush plate 15 removes the impurities remaining on filter screen barrel 4, and scraper 14 removes the impurities remaining on the inner wall of centrifuge barrel 5, achieving the effect of cleaning impurities. After cleaning, drain port 16 can be opened so that the cleaned impurities can be discharged from drain port 16. Box door 20 is set on one side of mounting box 1. The impurities discharged from drain port 16 can be treated by opening box door 20.

[0024] See Figure 2 A centrifuge tank 5 is provided on the outside of the filter screen tank 4. The bottom of the filter screen tank 4 is fixedly connected to the centrifuge tank 5. A synchronous wheel 8 is sleeved on the rotating shaft. There are two synchronous wheels 8. The outer sides of the two synchronous wheels 8 are tensioned together by a synchronous belt 9. A protrusion 18 is fixedly connected to the bottom of one of the synchronous wheels 8. The protrusion 18 abuts against the outer side of the centrifuge tank 5.

[0025] By setting the protrusion 18, when the servo motor 7 drives the mounting rod 13 to rotate, the synchronous wheel 8 at the bottom of the servo motor 7 rotates synchronously. There are two synchronous wheels 8. The synchronous belt 9 on the two synchronous wheels 8 is stretched together to make the two synchronous wheels 8 move synchronously. The protrusion 18 connected to the bottom of one of the synchronous wheels 8 moves synchronously. One end of the protrusion 18 is equipped with a compression spring, and the other end of the compression spring is connected to an abutment block. When the protrusion 18 moves, the abutment block abuts against the centrifuge barrel 5, and the compression spring is squeezed. When the abutment block moves with the protrusion 18, it passes through the centrifuge barrel 5, causing the centrifuge barrel 5 to vibrate, which facilitates the falling of impurities on the centrifuge barrel 5.

[0026] See Figure 3 A drive motor 3 is fixedly installed on the top of the mounting box 1. A connecting plate 6 is fixedly connected to the drive end of the drive motor 3. The outer side of the connecting plate 6 is fixedly connected to the inner wall of the filter screen barrel 4.

[0027] By setting up a connecting plate 6, the drive end of the drive motor 3 is connected to the connecting plate 6, so that when the connecting plate 6 rotates, it drives the filter screen bucket 4 to rotate, thereby driving the filter screen bucket 4 and the centrifuge bucket 5 to rotate, realizing the centrifugal operation of water-reducing agent production.

[0028] See Figure 5 The top of the mounting box 1 is provided with a sliding groove 19, and a connecting block 12 is fixedly connected to the top of the driven gear ring 11. The connecting block 12 is slidably connected to the sliding groove 19.

[0029] It should be noted that the cross-section of the connecting block 12 is set to "T" shape, and the cross-sectional shape of the groove 19 is adapted to the cross-section of the connecting block 12.

[0030] By making the connecting block 12 slidably connected to the slide groove 19, the stability of the driven gear ring 11 sliding on the top of the inner wall of the mounting box 1 is improved.

[0031] See Figure 2 The bottom of the filter screen bucket 4 is fixedly connected to the discharge port 17, which is movably connected to the bottom of the mounting box 1.

[0032] By movably connecting the discharge port 17 to the bottom of the mounting box 1, the discharge port 17 can rotate at the bottom of the mounting box 1 as the filter screen barrel 4 and the centrifuge barrel 5 rotate, thus improving the stability of the rotation.

[0033] See Figure 1 The bottom of the mounting box 1 is fixedly connected to a support frame. There are four support frames, which are fixedly connected to the four corners of the bottom of the mounting box 1.

[0034] By setting up a support frame, the installation box 1 is at a certain height above the ground, which facilitates the connection between the receiving device and the discharge port 17 to collect the produced centrifugal devices.

[0035] See Figure 1 A door 20 is movably provided on the outer side of the installation box 1, and a handle is fixedly connected to the outer side of the door 20.

[0036] By setting the door 20, after cleaning is completed, the door 20 can be opened to open the valve of the drain outlet 16 and treat the impurities discharged from the drain outlet 16.

[0037] Working principle: When using the device, the operator injects the water-reducing agent raw material into the filter barrel 4 through the feed port 2, starts the drive motor 3, and the filter barrel 4 and centrifuge barrel 5 rotate inside the mounting box 1. During centrifugation, impurities are thrown to the inner wall of the centrifuge barrel 5 through the filter holes on the outer wall of the filter barrel 4. The centrifuged water-reducing agent concentrate can flow out through the discharge port 17. After centrifugation, the drive motor 3 can be turned off to remove the precipitated impurities attached to the inner wall of the centrifuge barrel 5 and the residual impurities on the filter holes of the filter barrel 4. The servo motor 7 is started to drive the drive gear 10 to rotate. When the drive gear 10 rotates, it drives the driven gear ring that meshes with it. 11 rotates, and the driven gear ring 11 slides in the slide groove 19 through the connecting block 12. The mounting rod 13 connected to the bottom of the driven gear ring 11 rotates synchronously with the driven gear ring 11. The mounting rod 13 is located between the filter screen barrel 4 and the centrifuge barrel 5. The brush plate 15 removes the impurities remaining on the filter holes of the filter screen barrel 4, and the scraper 14 removes the impurities remaining on the inner wall of the centrifuge barrel 5, thereby achieving the effect of cleaning impurities. After cleaning, the drain port 16 can be opened so that the cleaned impurities can be discharged from the drain port 16. The box door 20 is set on one side of the installation box 1. The impurities discharged from the drain port 16 can be processed by opening the box door 20.

[0038] When the servo motor 7 drives the mounting rod 13 to rotate, the synchronous wheel 8 at the bottom of the servo motor 7 rotates synchronously. There are two synchronous wheels 8. The synchronous belt 9 on the two synchronous wheels 8 is stretched together, which makes the two synchronous wheels 8 move synchronously. The protrusion 18 connected to the bottom of one of the synchronous wheels 8 moves synchronously. One end of the protrusion 18 is equipped with a compression spring, and the other end of the compression spring is connected to an abutment block. When the protrusion 18 moves, the abutment block abuts against the centrifuge barrel 5, and the compression spring is squeezed. When the abutment block moves with the protrusion 18, it passes through the centrifuge barrel 5, causing the centrifuge barrel 5 to vibrate, which makes it easier for impurities on the centrifuge barrel 5 to fall off.
