Description

Technical Field

[0001] This invention relates to the field of thickener technology, specifically to an intelligent thickener underflow discharge device. Background Technology

[0002] A thickener underflow discharge device is a device or system used to discharge material (usually solid particles or sludge) deposited at the bottom of a thickener. Its main function is to ensure that the material deposited at the bottom during the thickening process can be discharged smoothly, thereby maintaining the continuous and efficient operation of the thickener.

[0003] The working principle of a thickener mainly relies on gravity settling and flocculation. During the thickening process, solid particles in the slurry gradually settle to the bottom of the tank under the influence of gravity, forming sediment. The sediment is continuously scraped by an underflow discharge device (such as a rake scraper) to the discharge port in the center of the tank bottom, and then discharged. At the same time, clarified water overflows from the top of the thickener, achieving solid-liquid separation.

[0004] Existing discharge devices typically use an absorption pump to discharge the sediment and underflow after scraping off the sediment. When the sediment concentration is high or the sediment particles are large, the absorption pump is prone to clogging and thus cannot work. In addition, the discharge speed of the absorption pump is fixed. When the underflow flow rate is large, the fixed discharge speed of the absorption pump can easily cause the outlet to become clogged. Summary of the Invention

[0006] This invention can be achieved through the following technical solution: It includes a tank body, inside which a scraping mechanism is provided for scraping the bottom sediment. The tank body also includes a vibration mechanism, which drives the scraping mechanism to vibrate, thereby discharging the scraped sediment from the discharge port. The tank body also includes a closing mechanism, which, when opened, causes the vibration mechanism to vibrate, discharging the material. The closing mechanism includes a conical cylinder, inside which a flow regulating mechanism is provided. This flow regulating mechanism can adjust the speed of bottom sediment discharge and also clear any blockages in the bottom sediment.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The scraping mechanism can scrape off the sediment at the bottom of the tank to prevent the sediment from caking. At the same time, the vibration mechanism is used to drive the scraping mechanism to vibrate, thereby concentrating the scraped sediment along the inclined bottom wall of the tank to the discharge port of the tank.

[0018] 3. The set flow regulation mechanism can control the discharge speed of the underflow according to the actual situation, thereby preventing the underflow from being blocked or discharged too slowly. Attached Figure Description

[0029] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0030] Please see Figure 1-8 As shown, the present invention provides an intelligent concentrator underflow discharge device, including a tank 1, a scraping mechanism 2 is provided inside the tank 1, the scraping mechanism 2 is used to scrape the underflow deposited at the bottom; a vibration mechanism 3 is also provided inside the tank 1, the vibration mechanism 3 is used to drive the scraping mechanism 2 to vibrate, thereby discharging the scraped deposits from the discharge port; a closing mechanism 4 is also provided on the tank 1, when the closing mechanism 4 is opened, the vibration mechanism 3 vibrates, thereby discharging the material, the closing mechanism 4 includes a conical cylinder 41, a flow regulating mechanism 5 is provided inside the conical cylinder 41, the flow regulating mechanism 5 can adjust the speed of underflow discharge and can also clear blocked underflow.

[0031] The scraping mechanism 2 can scrape off the sediment at the bottom of the tank 1 to prevent the sediment from caking. At the same time, the vibration mechanism 3 is used to drive the scraping mechanism 2 to vibrate, thereby concentrating the scraped sediment along the inclined bottom wall of the tank 1 to the discharge port of the tank 1. The vibration mechanism 3 can also prevent the discharge port from being blocked, and discharge the material at the discharge port through vibration.

[0032] The closure mechanism 4 is driven by the vibration mechanism 3 to achieve automatic intermittent discharge of the underflow. Compared with the traditional manual control method, it realizes automated discharge. At the same time, when the vibration mechanism 3 vibrates, the closure mechanism 4 moves synchronously, so as to discharge the sediment that is vibrated down in time and avoid blockage.

[0033] The flow regulation mechanism 5 can control the discharge speed of the underflow according to the actual situation, thereby preventing the underflow from becoming blocked or being discharged too slowly.

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

[0035] The scraping mechanism 2 operates as follows: First, the first motor 21 is started, which drives the rotating shaft 22 to rotate. The rotating shaft 22 further drives the rotating rod 23 on it to rotate. 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 at the same time, due to the rotation of the first motor 21, it obtains centrifugal force, which drives the scraper 24 to adhere to the bottom wall of the tank 1. During the rotation process, the scraper 24 scrapes the bottom wall of the tank 1, thereby removing the hardened deposits.

[0036] Please see Figure 2-4 As shown, the vibration mechanism 3 includes a slide rod 31, a limit rail 38 is provided on the rotating shaft 22, a limit 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 limit rail 38, and the other end of the slide rod 31 is rotatably connected to a pulley 35, which is slidably connected in the limit groove 32. The limit groove 32 is composed of an annular groove and multiple arc grooves.

[0037] Please see Figure 2-4 As shown, a protrusion 33 is fixedly connected to the slide rod 31. The protrusion 33 is in contact with the rotating rod 23. A limit frame 34 is provided on the rotating rod 23. The limit frame 34 and the slide rod 31 are slidably connected.

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

[0039] Driven by the first motor 21, the limiting rail 38 mounted on the rotating shaft 22 rotates synchronously. The slide rod 31 sliding on the limiting rail 38 rotates with the limiting rail 38. At the same time, the pulley 35 on the slide rod 31 is slidably connected in the limiting groove 32. When it rotates to the arc-shaped groove part on the limiting groove 32, the pulley 35 drives the slide rod 31 to descend. At the same time, the protrusion 33 on the slide rod 31 descends synchronously. The protrusion 33 then strikes the rotating rod 23 downwards. The rotating rod 23 then drives the telescopic rod 25 to strike the scraper 24 downwards synchronously. At this time, the first spring 36 is stretched. When the pulley 35 moves to the annular groove part of the limiting 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 back to its original position.

[0040] Please see Figure 6-8As shown, the closing mechanism 4 includes a conical cylinder 41, which is slidably connected to the outlet of the tank 1. A limit 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. A second spring 44 is provided inside the fixed cylinder 43. The second spring 44 is connected to the limit rod 45. A transmission rod 42 is rotatably connected to the limit rod 45. The end of the transmission rod 42 away from the limit rod 45 is rotatably connected to the rotating rod 23.

[0041] When the rotating rod 23 on the vibration mechanism 3 rotates downward, the closing mechanism 4 moves synchronously. When the rotating rod 23 rotates, the transmission rod 42 rotatably connected to the rotating rod 23 rotates. The transmission rod 42 further pushes the limiting rod 45 to move. The limiting rod 45 drives the conical cylinder 41 connected to it to move until the conical cylinder 41 leaves the discharge port of the tank 1. The second spring 44 and the fixed cylinder 43 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, the conical cylinder 41 and the discharge port of the tank 1 are aligned, thus realizing the closure of the tank 1.

[0042] Please see Figure 8 As shown, the flow regulating mechanism 5 includes a second motor 51, which is installed inside a conical cylinder 41. A sealing box is provided inside the conical cylinder 41. A hydraulic cylinder 52 is installed 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. The end of the push rod 54 away from the connecting rod 53 is rotatably connected to the sealing plate 55.

[0043] Please see Figure 7 As shown, a cover 7 is rotatably connected to the conical cylinder 41, a sealing plate 55 is rotatably connected to the cover 7, and a drain rod 6 is fixedly connected to the cover 7.

[0044] Please see Figure 8 As shown, a first telescopic plate 56 is slidably connected inside the sealing plate 55, and 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 7. When the sealing plate 55 rotates into the inside of the conical cylinder 41, the taper changes, so the length of the sealing plate 55 needs to change. The function of the first telescopic plate 56 and the second telescopic plate 57 is to prevent the sealing plate 55 from being too short to complete the seal when it returns to its original position.

[0045] The flow regulating mechanism 5 is activated when the conical cylinder 41 in the closing mechanism 4 moves below the discharge port, thereby further increasing the discharge speed and preventing blockage. Simultaneously, the flow regulating mechanism 5 itself can adjust the flow rate. By activating the second motor 51, the second motor 51 further drives the hydraulic cylinder 52, connecting rod 53, push rod 54, sealing plate 55, and cover 7 to rotate. At this time, the unblocking rod 6 on the cover 7 rotates. The unblocking rod 6 is located at the discharge port of the tank 1, thus unblocking the discharge port and preventing blockage. It can also adjust the underflow discharge speed. By activating the hydraulic cylinder 52, the hydraulic cylinder 52 drives the connecting rod 53, which is fixedly connected to it, to move. The connecting rod 53 further drives the push rod 54 on it to move. At this time, the push rod 54 rotates, causing the sealing plate 55 to rotate. Therefore, the opening size of the sealing plate 55 and the cover 7 can be adjusted according to the rotation amplitude of the sealing plate 55, thereby completing the adjustment of the discharge speed.

[0046] In use, the slurry is first introduced into the tank 1 through an absorption pump. The slurry gradually settles to the bottom of the tank through gravity settling and flocculation, forming sediment. The sediment is scraped off by the scraping mechanism 2, and then discharged from the discharge port of the tank 1 in conjunction with the vibration mechanism 3. The closing mechanism 4, driven by the vibration mechanism 3, operates synchronously to open the discharge port of the tank 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.
