Description

Technical Field

[0002] With the rapid development of global industry, especially in the fields of mining, chemical industry, environmental protection, etc., the demand for solid-liquid separation technology is growing. As a highly efficient solid-liquid separation equipment, deep cone thickener has been widely used in many industries due to its advantages such as large processing capacity, small footprint, and high degree of automation. When the deep cone thickener is working, the material enters the central area of ​​the thickener through the feed pipe, and then the material in the thickener settles to the bottom of the thickener under the action of gravity, forming a thick layer of mud cake, while the clear liquid flows out from the overflow port at the top of the thickener, thereby realizing solid-liquid separation. During this period, the rake at the bottom rotates slowly to stir the mud cake to prevent it from being too densely stacked, thereby promoting the separation and discharge of solids and liquids. Finally, the thick slurry after sedimentation and stirring is discharged from the discharge port at the bottom.

[0003] However, when the feed pipe of a traditional deep cone thickener delivers materials into the central area of ​​the thickener, the materials may accumulate directly at the bottom of the thickener, thereby affecting the solid-liquid separation and sedimentation efficiency of the materials.

[0023] See also Figure 8 As shown, the diversion mechanism includes a solenoid valve 1702 and a hose 1701. The two ends of the hose 1701 are respectively connected to the second nozzle 15 and the first water pipe 1602. The hose 1701 is used to divert the clean water in the first water pipe 1602 to the second nozzle 15. The solenoid valve 1702 is installed on the hose 1701.

[0024] See also Figure 6-Figure 8 As shown, the lifting mechanism includes a waterproof motor 1801, a winding drum 1802 and a connecting rope 1803. The waterproof motor 1801 is symmetrically fixedly arranged at the bottom of the bridge frame 2 and located on the left and right sides of the top of the hollow cylinder 10, and the winding drum 1802 is also symmetrically rotated and arranged at the bottom of the bridge frame 2 and located on the left and right sides of the top of the hollow cylinder 10. The winding drum 1802 is located at the front side of the waterproof motor 1801, and the winding drum 1802 is connected to the output shaft of the waterproof motor 1801; the connecting rope 1803 is wound around the winding drum 1802, one end of the connecting rope 1803 is connected to the winding drum 1802, and the other end of the connecting rope 1803 is connected to the sliding frame 14.

[0025] When in use, the material is continuously transported to the storage space in the hollow cylinder 10 through the feeding pipe 11 (the material in the storage space is under the rotating plate 1603). The storage space acts as a buffer for the incoming material. The material in the storage space is then evenly dispersed on the inner side of the tank body 1 and the funnel 3 through the dispersion pipe 12, so that the material naturally settles in the tank body 1 and the funnel 3, so that the concentrated slurry in the material sinks into the funnel 3 under the action of gravity for accumulation, and the clear liquid in the material overflows from the top of the tank body 1 to the overflow trough 101 for collection, and then the clear liquid in the overflow trough 101 is extracted. In this way, the solid-liquid separation of the material can be achieved. When the material is subjected to solid-liquid separation, the driving motor 5 is started at the same time to drive the rotating rod 6, the rake frame 7, the connecting plate 71, the connecting rod 801 and the stirring wire 802 to rotate, so that the rake frame 7, the connecting plate 71 and the stirring wire 802 stir the materials in the tank body 1 and the funnel 3, thereby preventing the materials in the tank body 1 and the funnel 3 from being too densely stacked, thereby promoting the solid-liquid separation in the material. After that, when a certain amount of concentrated slurry is accumulated in the tank body 1 and the funnel 3, the discharge port 4 is opened to discharge the concentrated slurry in the tank body 1 and the funnel 3. During this period, the concentrated slurry in the tank body 1 and the funnel 3 is stirred by the rake frame 7, the connecting plate 71 and the stirring wire 802, which can speed up the discharge of the concentrated slurry in the tank body 1 and the funnel 3. After a certain amount of concentrated slurry in the tank body 1 and the funnel 3 is discharged, the discharge port 4 is closed, and the above operation is repeated to continuously separate the material from solid and liquid.When the solid-liquid separation of all materials is completed, the operator needs to clean the tank body 1 and the funnel 3. The operator continuously delivers clean water to the storage space in the hollow cylinder 10 through the feeding pipe 11, so as to flush the inside of the storage space, and discharge the clean water from the dispersion pipe 12 through the storage space, and flush the dispersion pipe 12 at the same time. After the flushing of the storage space and the dispersion pipe 12 is completed, the water pump 1601 is started to pump the clean water into the first water pipe 1602, so that the clean water flows from the first water pipe 1602 into the storage space in the hollow cylinder 10, and the clean water in the storage space is above the rotating plate 1603, so that the rotating plate 16 03 enters the first spray pipe 13 through the second water pipe 1604, so that the first spray pipe 13 sprays the clean water into the tank body 1 and the funnel 3, and then rinses the tank body 1 and the funnel 3. As the rotating rod 6 and the rake frame 7 drive the sleeve 9, the rotating plate 1603, the second water pipe 1604 and the first spray pipe 13 to rotate, the first spray pipe 13 can spray the clean water evenly into the tank body 1 and the funnel 3, so that the tank body 1 and the funnel 3 are fully rinsed, and the rinsed clean water is discharged through the discharge port 4. When the tank body 1 and the funnel 3 are fully rinsed, the solenoid valve 1702 is controlled to open at the same time, so that the first water pipe 1702 is opened. The clean water in 1602 flows into the second nozzle 15 through the hose 1701, so that the second nozzle 15 sprays the clean water on the outside of the hollow cylinder 10, and then washes the outside of the hollow cylinder 10. After the outside of the hollow cylinder 10 is washed, the waterproof motor 1801 drives the winding drum 1802 to rotate, so that the winding drum 1802 unwinds the connecting rope 1803, so that the connecting rope 1803 releases the sliding frame 14. At this time, the sliding frame 14 and the second nozzle 15 descend under the action of gravity, so that the sliding frame 14 and the second nozzle 15 gradually approach the rake frame 7, so that the second nozzle 15 can spray the clean water on the rake frame 7, from The rake frame 7 is flushed. After the flushing of the rake frame 7 is completed, the waterproof motor 1801 drives the winding drum 1802 to reverse and reset, so that the winding drum 1802 reels the connecting rope 1803, so that the connecting rope 1803 pulls the sliding frame 14 and the second nozzle 15 to rise and reset, and then the solenoid valve 1702 is controlled to be closed. When the tank body 1 and the funnel 3 are fully flushed, the water pump 1601 is turned off, and then the driving motor 5 is turned off to stop the rotating rod 6, the rake frame 7, the connecting plate 71, the connecting rod 801 and the stirring wire 802 from rotating. In this way, the tank body 1 and the funnel 3 can be automatically flushed in an all-round way.

[0026] See also Fig. 9 and Fig.10As shown, the high-efficiency deep cone thickener also includes a perforated circular plate 19, a rotating frame 20 and a toggle plate 21. A perforated circular plate 19 is provided on the cross section of the connection between the tank body 1 and the funnel 3, the bottom end of the rotating rod 6 passes through the perforated circular plate 19 and rotates with the perforated circular plate 19, and a plurality of through holes are evenly arranged on the perforated circular plate 19, and the perforated circular plate 19 is used to block foreign objects falling into the funnel 3. In this embodiment, the rotating frame 20 is rotatably installed in the middle of the perforated circular plate 19 through a bearing, that is, the bearing is installed in the middle of the perforated circular plate 19, the rotating frame 20 is installed in the bearing, the bottom end of the rotating rod 6 passes through the rotating frame 20, and the rotating rod 6 can drive the rotating frame 20 to rotate when it rotates. The top of the rotating frame 20 is connected to the three second water pipes 1604 so that the rotating rod 6, the three second water pipes 1604 and the rotating frame 20 rotate synchronously; a toggle plate 21 is connected to the rotating frame 20, and the bottom of the toggle plate 21 is in sliding contact with the top of the perforated circular plate 19, and the toggle plate 21 is used to push foreign objects that stay on the perforated circular plate 19.

[0027] The present invention provides a perforated circular plate 19. When foreign matter falls into the funnel 3 through the tank body 1 (since the tank body 1 is usually set in the open air, foreign matter from the outside can easily enter the tank body 1), the perforated circular plate 19 can block the foreign matter and make the foreign matter stay on the top of the perforated circular plate 19, thereby preventing the foreign matter from falling into the discharge port 4 and causing blockage, while the material in the tank body 1 is not affected by the perforated circular plate 19, so that the material can normally pass through the perforated circular plate 19 into the funnel 3; when the rotating rod 6 and the rake frame 7 drive the sleeve 9, the rotating plate 1603, the second water pipe 1604 and the first nozzle 13 to rotate, the second water pipe 1604 will drive the rotating frame 20 and the toggle plate 21 to rotate, so that the toggle plate 21 pushes the foreign matter staying on the perforated circular plate 19 to move, thereby preventing the foreign matter from clogging at the same position on the perforated circular plate 19 for a long time, and then making the material in all directions in the tank body 1 pass through the perforated circular plate 19 evenly into the funnel 3.

[0028] See also Fig.11 and Fig.12 As shown, the high-efficiency deep cone thickener also includes a scraping mechanism, which includes a scraper 22, an elastic rope 23 and a connecting pipe 24. A rectangular chute is arranged inside the connecting plate 71 and near the bottom. The scraper 22 is installed in the chute and slides with the chute in the vertical direction. The bottom of the scraper 22 extends downward from the bottom of the connecting plate 71. The scraper 22 is used to scrape the thick slurry remaining on the inner wall of the tank body 1. The elastic rope 23 is arranged in the chute and is located between the top of the chute and the top of the scraper 22. One end of the elastic rope 23 is connected to the top of the chute, and the other end of the elastic rope 23 is connected to the top of the scraper 22. Four elastic ropes 23 are evenly arranged between the top of the scraper 22 and the top of the chute of the connecting plate 71. A connecting pipe 24 is connected to the connecting plate 71. The lower end of the connecting pipe 24 is located at the top of the chute of the connecting plate 71, and the upper end of the connecting pipe 24 is connected to the first nozzle 13.

[0029] When the clean water enters the first nozzle 13, part of the clean water will enter the top of the chute of the connecting plate 71 through the connecting pipe 24, and the clean water will squeeze the scraper 22 in the connecting plate 71 to move downward, and the elastic rope 23 will be deformed, so that the scraper 22 contacts the inner wall of the tank body 1, and then as the rake frame 7 drives the connecting plate 71 and the scraper 22 to rotate in the tank body 1, the scraper 22 can scrape off the thick slurry remaining on the inner wall of the tank body 1 to prevent the thick slurry from remaining on the inner wall of the tank body 1; when the water pump 1601 is turned off, the clean water flowing into the chute of the connecting plate 71 gradually decreases, when the pressure of the clean water on the connecting plate 71 is less than the elastic force of the elastic rope 23, the elastic rope 23 returns to its original state, and the elastic rope 23 drives the scraper 22 in the connecting plate 71 to move upward and reset, so that the scraper 22 is separated from the inner wall of the tank body 1, and when the rake frame 7 stops rotating, the connecting plate 71 and the scraper 22 stop rotating together.

"Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect. The subsequent description of the specification is a preferred embodiment of the present application, but the description is for the purpose of illustrating the general principles of the present application, and is not used to limit the scope of the present application. The scope of protection of the present application shall be determined by the definition of the attached claims.

[0032] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such a product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.

[0033] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0034] The above description shows and describes several preferred embodiments of the present application, but as mentioned above, it should be understood that the present application is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the application concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the present application, and should be protected by the specification attached to the present application.
