Description

Technical Field

[0001] The invention relates to the technical field of concentrators, and in particular to an underflow discharge device for an intelligent concentrator. Background Art

[0002] The underflow discharge device of the concentrator refers to the equipment or system used to discharge the materials (usually solid particles or sludge) deposited at the bottom of the concentrator. Its main function is to ensure that the materials deposited at the bottom during the concentrating process can be discharged smoothly, so as to maintain the continuous and efficient operation of the concentrator.

[0003] The working principle of the concentrator mainly relies on gravity sedimentation and flocculation. During the concentration process, the solid particles in the slurry gradually settle to the bottom of the pool under the action of gravity to form sediment. The sediment is continuously scraped and collected by the bottom flow discharge device (such as a rake scraper) to the discharge port in the center of the pool bottom, and then discharged. At the same time, clarified water overflows from the upper edge of the concentration tank to achieve solid-liquid separation.

[0004] After the existing discharge device scrapes off the sediment, it usually uses an absorption pump to discharge the sediment and the underflow. When the concentration of the sediment is high or the sediment particles are large, it is easy to cause the absorption pump to be blocked and thus unable to work. In addition, the discharge speed of the absorption pump is fixed. When the flow rate of the underflow is large, it is easy to cause the discharge port to be blocked at the fixed discharge speed of the absorption pump. Summary of the invention

DETAILED DESCRIPTION

[0029] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0030] See also Figure 1-8 As shown, the present invention provides an underflow discharge device for an intelligent concentrator, comprising a tank body 1, a scraping mechanism 2 is arranged in the tank body 1, and the scraping mechanism 2 is used to scrape the underflow deposited at the bottom; a vibrating mechanism 3 is also arranged in the tank body 1, and the vibrating mechanism 3 is used to drive the scraping mechanism 2 to vibrate so as to discharge the scraped sediment from the discharge port; a closing mechanism 4 is also arranged on the tank body 1, and when the closing mechanism 4 is opened, the vibrating mechanism 3 just vibrates to discharge the material, and the closing mechanism 4 comprises a conical cylinder 41, and a flow regulating mechanism 5 is arranged in the conical cylinder 41, and the flow regulating mechanism 5 can adjust the speed of underflow discharge and can also dredge the blocked underflow.

[0031] The scraping mechanism 2 is capable of scraping off the sediment at the bottom of the tank body 1 to prevent the sediment from hardening. The vibrating mechanism 3 is also capable of driving the scraping mechanism 2 to vibrate, thereby concentrating the scraped sediment along the inclined bottom wall of the tank body 1 to the discharge port of the tank body 1. The vibrating mechanism 3 can also prevent the discharge port from being blocked, and discharge the material at the discharge port by vibration.

[0032] The closing mechanism 4 is driven by the vibration mechanism 3 to realize automatic interval discharge of the bottom flow. Compared with the traditional manual control method, automatic discharge is realized. At the same time, when the vibration mechanism 3 vibrates, the closing mechanism 4 acts synchronously, so that the sediment vibrated down can be discharged in time, thereby avoiding blockage.

[0033] The flow regulating mechanism 5 can control the discharge speed of the underflow according to the actual situation, so as to prevent the underflow from being blocked or being discharged too slowly.

[0034] See also Figure 2-4As shown, the scraping mechanism 2 includes a first motor 21, which is installed above the tank body 1. The output end of the first motor 21 is fixedly connected to a rotating shaft 22, and a rotating rod 23 is rotatably connected to the rotating shaft 22. A telescopic rod 25 is rotatably connected to the rotating rod 23, and a scraper 24 is connected to the end of the telescopic rod 25 away from the rotating rod 23. The scraper 24 is in sliding contact with the conical surface of the tank body 1.

[0035] The operation process of the scraping mechanism 2 is as follows: first start the first motor 21, the first motor 21 drives the rotating shaft 22 to rotate, the rotating shaft 22 further drives the rotating rod 23 thereon to rotate, and the telescopic rod 25 and the scraper 24 connected to the rotating rod 23 rotate synchronously. Since the scraper 24 is connected to the rotating rod 23 through the telescopic rod 25 and the rotating rod 23, and at the same time due to the rotation of the first motor 21, centrifugal force is obtained, driving the scraper 24 and the bottom wall of the tank body 1 to fit together. During the rotation process, the bottom wall of the tank body 1 is scraped, thereby scraping off the compacted sediment.

[0036] See also Figure 2-4 As shown, the vibration mechanism 3 includes a slide rod 31, a limiting rail 38 is arranged on the rotating shaft 22, a limiting groove 32 is opened on the inner wall of the tank body 1, one end of the slide rod 31 is slidably connected in the limiting rail 38, and the other end of the slide rod 31 is rotatably connected to a pulley 35, and the pulley 35 is slidably connected in the limiting groove 32, and the limiting groove 32 is composed of an annular groove and a plurality of arc grooves.

[0037] See also Figure 2-4 As shown, a protrusion 33 is fixedly connected to the slide bar 31 , and the protrusion 33 contacts the rotating bar 23 . A limit frame 34 is provided on the rotating bar 23 , and the limit frame 34 is slidably connected to the slide bar 31 .

[0038] See also Figure 2 As shown, a mounting plate 37 is fixedly connected to the rotating shaft 22 , and a first spring 36 is arranged between the mounting plate 37 and the rotating rod 23 .

[0039] Driven by the first motor 21, the limit rail 38 installed on the rotating shaft 22 rotates synchronously, and the sliding rod 31 sliding on the limit rail 38 rotates along with the limit rail 38. At the same time, the pulley 35 on the sliding rod 31 is slidably connected in the limit groove 32. When it rotates to the arc groove part on the limit groove 32, the pulley 35 drives the sliding rod 31 to descend, and at the same time, the protrusion 33 on the sliding rod 31 descends synchronously, and the protrusion 33 thereby knocks the rotating rod 23 downward, and the rotating rod 23 thereby drives the telescopic rod 25 to knock the scraper 24 downward synchronously. At this time, the first spring 36 is stretched, and when the pulley 35 moves to the annular groove part of the limit groove 32 and the protrusion 33 no longer acts on the rotating rod 23, the first spring 36 restores its elastic deformation and pulls the rotating rod 23 to move to its original position.

[0040] See also Figure 6-8As shown, the closing mechanism 4 includes a conical cylinder 41, which is slidably connected to the discharge port of the tank body 1, and a limiting rod 45 is fixedly connected to the top of the conical cylinder 41. A fixed cylinder 43 is fixedly connected to the rotating shaft 22, and a second spring 44 is arranged in the fixed cylinder 43. The second spring 44 is connected to the limiting rod 45, and a transmission rod 42 is rotatably connected to the limiting rod 45. The end of the transmission rod 42 away from the limiting rod 45 is rotatably connected to the rotating rod 23.

[0041] The closing mechanism 4 moves synchronously when the rotating rod 23 on the vibrating mechanism 3 rotates downward. When the rotating rod 23 rotates, the transmission rod 42 connected to the rotating rod 23 rotates, and the transmission rod 42 further pushes the limit rod 45 to move. The limit rod 45 drives the conical cylinder 41 connected thereto to move until the conical cylinder 41 leaves the discharge port of the tank body 1. The second spring 44 and the fixed cylinder 43 are arranged, which can pull the conical cylinder 41 back to its original position when the transmission rod 42 does not act on the conical cylinder 41, that is, overlap the conical cylinder 41 and the discharge port of the tank body 1, thereby realizing the closure of the tank body 1.

[0042] See also Figure 8 As shown, the flow regulating mechanism 5 includes a second motor 51, which is installed in the conical cylinder 41. A sealing box is provided in the conical cylinder 41. The second motor 51 is installed in the sealing box. A hydraulic cylinder 52 is provided on the sealing box. A connecting rod 53 is fixedly connected to the telescopic end of the hydraulic cylinder 52. A sealing plate 55 is rotatably connected to the conical cylinder 41. The connecting rod 53 drives the sealing plate 55 to rotate. A push rod 54 is rotatably connected to the connecting rod 53. One end of the push rod 54 away from the connecting rod 53 is rotatably connected to the sealing plate 55.

[0043] See also Figure 7 As shown, the conical cylinder 41 is rotatably connected to a cover body 7 , the sealing plate 55 is rotatably connected to the cover body 7 , and the cover body 7 is fixedly connected to a dredging rod 6 .

[0044] See also Figure 8 As shown, a first telescopic plate 56 is slidably connected inside the sealing plate 55, an elastic component is provided inside the sealing plate 55, the elastic component is connected to the first telescopic plate 56, and a second telescopic plate 57 is elastically connected inside the cover body 7. When the sealing plate 55 rotates to the inside of the conical cylinder 41, the taper changes, so the length of the sealing plate 55 needs to change. The purpose of the first telescopic plate 56 and the second telescopic plate 57 is to prevent the sealing plate 55 from being insufficient in length when returning to its original position, thereby failing to complete the sealing.

[0045] The flow regulating mechanism 5 is used to start the flow regulating mechanism 5 after the conical cylinder 41 in the closing mechanism 4 moves to the bottom of the discharge port, so as to further increase the discharge speed and prevent it from being blocked. At the same time, the flow regulating mechanism 5 itself can adjust the flow rate. By starting the second motor 51, the second motor 51 further drives the hydraulic cylinder 52, the connecting rod 53, the push rod 54, the sealing plate 55 and the cover body 7 to rotate. At this time, the dredging rod 6 on the cover body 7 rotates. The dredging rod 6 is located at the discharge port of the tank body 1, so that the discharge port can be dredged to avoid blockage of the discharge port. At the same time, the bottom flow discharge speed can also be adjusted. By starting the hydraulic cylinder 52, the hydraulic cylinder 52 drives the connecting rod 53 fixedly connected thereto to move, and the connecting rod 53 further drives the push rod 54 thereon to move. At this time, the push rod 54 rotates, driving the sealing plate 55 to rotate, so that the opening size of the sealing plate 55 and the cover body 7 can be adjusted according to the rotation amplitude of the sealing plate 55, thereby completing the adjustment of the discharge speed.

[0046] When the present invention is in use, the slurry is first introduced into the tank body 1 through the absorption pump. The slurry gradually settles to the bottom of the pool through gravity sedimentation and flocculation to form sediment. The sediment is scraped off by the scraping mechanism 2, and then the scraped sediment is discharged from the discharge port of the tank body 1 in cooperation with the vibration mechanism 3. The closing mechanism 4 is driven by the vibration mechanism 3 to synchronously operate to open the discharge port of the tank body 1, thereby discharging the material. The flow regulating mechanism 5 can adjust the discharge speed as needed to prevent the discharge speed from being too slow and causing blockage.

Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
