Description

Technical Field

[0001] This utility model relates to the field of thickener equipment technology, specifically to a thickener that facilitates overflow control. Background Technology

[0002] A thickener is a solid-liquid separation device based on gravity sedimentation. It can concentrate slurry with a solid content of 10% to 20% into underflow slurry with a solid content of 45% to 55% through gravity sedimentation. With the help of a rake installed inside the thickener and rotating slowly, the thickened underflow slurry is discharged from the underflow port at the bottom of the thickener. The advantages of a thickener are simple structure, convenient operation, low power consumption, and good technical performance.

[0003] Existing thickeners, when operating, are prone to overflow if too much material is fed at once or if pipe blockage occurs, due to excessive liquid accumulation at the top of the thickener. This overflow results in waste, contaminates the equipment, makes subsequent cleaning of the equipment and working environment difficult, increases production costs, and affects work efficiency. Therefore, this solution provides a thickener with easily controllable overflow to address the aforementioned problems. Utility Model Content

An activation switch for activating the alarm is fixedly installed on the installation plate on the upper side of the lifting block.

[0012] Compared with the prior art, this utility model proposes a thickener that facilitates overflow control, and has the following beneficial effects:

[0013] 1. In this utility model, the overflow port of the sedimentation funnel cooperates with the overflow component to realize the directional delivery of the clarified liquid; at the same time, the float of the collection box, driven by the collected overflow liquid, lifts the lifting block through the vertical rod, thereby activating the start switch on the upper mounting plate, thereby triggering the alarm to realize real-time monitoring of the liquid level and triggering the early warning, effectively solving the problem of difficult overflow control and easy overflow of traditional thickeners.

An overflow component 4 is arranged on the outside of the overflow port 301. The lower end of the overflow component 4 is connected to the collection box 6, and a filter component 5 is arranged inside the overflow component 4.

[0029] Furthermore, in this device, the overflow port 301 of the sedimentation funnel 3 cooperates with the overflow component 4 to realize the directional delivery of the clarified liquid; at the same time, the float 603 of the collection box 6, driven by the collected overflow liquid, lifts the lifting block 605 through the vertical rod 604, thereby activating the start switch 607 on the upper mounting plate 606, thereby triggering the alarm 7 to sound an alarm, realizing real-time monitoring of the liquid level and triggering an early warning, effectively solving the problems of difficult overflow control and easy overflow of traditional thickeners.

[0030] Reference Figure 3-5 As shown, specifically in this embodiment, the filter assembly 5 includes a filter plate 501 for filtering. The upper end of the filter plate 501 is inclined and has several sets of filter holes 502 through it. The lower end surface of the filter plate 501 has several sets of filter holes 503 through it. A cleaning component 1 for cleaning is provided on the lower side of the filter hole 502, and a cleaning component 2 for cleaning is provided on the rear side of the filter hole 503.

[0031] Furthermore, the top of the filter plate 501 is inclined, and filter holes 502 are provided on the inclined surface. Filter holes 503 are provided through the lower surface. Since the sedimentation funnel 3 is an open structure, it is easy to carry debris such as fallen leaves during overflow. The overflow port 301 can effectively isolate some large debris. Then, the filter plate 501 can intercept the remaining debris, preventing it from entering the overflow collection box 6 and ensuring the purity of the overflow liquid. At the same time, the inclined structure design makes it easy to concentrate the debris to the side of the filter box 403 for regular cleaning. Meanwhile, the cleaning components 1 and 2 driven by the electric push rod 504 can actively remove the blockage of filter holes 502 and 503, ensuring stable filtration efficiency, reducing equipment failure rate, and effectively reducing the number of equipment maintenance.

[0032] Reference Figure 2 As shown, specifically in this embodiment, the overflow assembly 4 includes an overflow funnel 401 and a filter box 403 fixedly installed on the sedimentation funnel 3. The overflow funnel 401 is located outside the overflow port 301. A first pipe 402 is fixedly installed at the lower end of the overflow funnel 401. The lower end of the first pipe 402 is connected to the upper end of the filter box 403.

A sealing door 405 is rotatably installed at the upper end of the filter box 403, and the filter assembly 5 is located inside the filter box 403.

[0033] Furthermore: the clarified liquid flows out through the overflow port 301 on the right side of the sedimentation funnel 3, while the overflow funnel 401 in the overflow assembly 4 is set outside the overflow port 301 to prevent the clarified liquid from splashing when it overflows; after the clarified liquid enters the overflow funnel 401, it flows into the filter box 403 for filtration through the lower pipe 402; the filtered liquid finally flows into the collection box 6 through the lower pipe 404 of the filter box 403, realizing the closed and orderly transportation of the overflow liquid and reducing pollution and waste.

[0034] The sealing door 405 at the top of the filter box 403 can be opened manually, which facilitates the subsequent cleaning of impurities inside the filter box 403 or the maintenance of the filter assembly 5, thus improving the convenience of equipment maintenance.

[0035] Reference Figure 3-5 As shown, specifically in this embodiment, the cleaning component includes a slide rail 508 symmetrically fixedly installed on the inner wall of the filter box 403. A movable plate 506 is slidably connected inside the slide rail 508. Several sets of top rods 507 matching the filter holes 502 are fixedly connected to the upper end of the movable plate 506. Two sets of springs 509 are symmetrically fixedly connected between the lower end of the movable plate 506 and the filter box 403.

[0036] Furthermore: by pushing the movable plate 506 to slide upward along the slide rail 508, the push rod 507 at the upper end of the movable plate 506 is inserted into the filter hole 502 to push out the impurities blocking the hole; after cleaning, the electric push rod 504 is reset, the spring 509 pulls the movable plate 506 back down, the push rod 507 exits the filter hole 502, and the filtration function is restored.

[0037] Reference Figure 3-5As shown, specifically in this embodiment, the cleaning component two includes two sets of fixing rods 5012 fixedly connected to the filter plate 501. A movable plate 5010 is slidably connected to the fixing rod 5012. Several sets of top rods 5011 adapted to the filter holes 503 are fixedly connected to the movable plate 5010. A fixing plate 5014 is fixedly connected to the rear end of the fixing rod 5012. A spring 5013 sleeved on the fixing rod 5012 is fixedly connected between the fixing plate 5014 and the movable plate 5010.

[0038] Furthermore: by pushing the movable plate 5010 to slide forward along the fixed rod 5012, the top rod 5011 on the movable plate 5010 is inserted into the filter hole 503 to remove the blockage impurities; when the electric push rod 504 is reset, the spring 5013 pulls the movable plate 5010 back, and the top rod 5011 exits the filter hole 503, completing the cleaning and reset.

[0039] Reference Figure 3-5 As shown, specifically in this embodiment, an electric push rod 504 is fixedly installed at the rear end of the filter box 403, and the output shaft of the electric push rod 504 is fixedly connected to a push plate 505 for driving the cleaning component one and the cleaning component two.

[0040] Furthermore: After filtering for a period of time, the electric push rod 504 is activated, which extends and drives the push plate 505 to move. During the movement of the push plate 505, the first moving plate 506 is pushed upward and the second moving plate 5010 slides forward, thereby driving the first cleaning component and the second cleaning component to clean the first filter hole 502 and the second filter hole 503.

[0041] Reference Figure 6 As shown, specifically in this embodiment, the collection box 6 includes a guide frame 601 fixedly installed on the inner wall of the collection box 6, and an mounting plate 606 fixedly installed on the top of the collection box 6. A sliding block 602 is slidably connected inside the guide frame 601. A float plate 603 is fixedly connected to the lower end of the sliding block 602. A vertical rod 604 is fixedly connected to the upper end of the sliding block 602. A lifting block 605 that slides on the collection box 6 is provided on the upper side of the vertical rod 604. A start switch 607 for activating the alarm 7 is fixedly installed on the mounting plate 606 on the upper side of the lifting block 605.

[0042] Furthermore, the collection tank 6 is equipped with a float plate 603 that floats on the surface of the liquid. When the liquid level in the collection tank 6 increases, the float plate 603 floats upward, causing the sliding block 602 connected to it to slide upward along the guide frame 601. The vertical rod 604 at the upper end of the sliding block 602 then rises accordingly, eventually lifting the lifting block 605 to move upward in sync. When the liquid level rises to near the upper limit of the capacity of the collection tank 6, the lifting block 605 moves upward and touches the start switch 607 fixed on the mounting plate 606, thereby activating the alarm 7 to remind the staff to deal with the overflow liquid in the collection tank 6 in time, avoid liquid overflow, realize the active control of the overflow of the collection tank 6, and prevent environmental pollution and material loss.

[0043] The working principle of this utility model is as follows: During use, the clarified liquid flows out through the overflow port 301 on the right side of the sedimentation funnel 3, while the overflow funnel 401 in the overflow assembly 4 is located outside the overflow port 301 to prevent the clarified liquid from splashing when it overflows; after the clarified liquid enters the overflow funnel 401, it flows into the filter box 403 through the lower pipe 402 for filtration treatment.

[0044] The filter assembly 5 is equipped with a filter plate 501. The top of the filter plate 501 is inclined and a filter hole 502 is opened on the inclined surface. A filter hole 503 is opened through the lower surface. Since the sedimentation funnel 3 is an open structure, it is easy to carry fallen leaves and other debris when overflowing. A portion of the large debris can be effectively isolated through the overflow port 301. Then, the filter plate 501 can intercept the remaining debris and prevent it from entering the overflow collection box 6, thus ensuring the purity of the overflow liquid. At the same time, the inclined structure design makes it easy to concentrate the debris to the side of the filter box 403 for regular cleaning.

[0045] After filtering for a period of time, the electric push rod 504 is activated. The electric push rod 504 extends and drives the push plate 505 to move. During the movement of the push plate 505, the moving plate 506 is pushed upward and the moving plate 5010 slides forward, thereby driving the moving plate 506 and the moving plate 5010 of the cleaning component 1 and the cleaning component 2 in a synchronized manner.

[0046] By pushing the movable plate 506 to slide upward along the slide rail 508, the push rod 507 at the upper end of the movable plate 506 is inserted into the filter hole 502 to push out the impurities blocking the hole.

[0047] By pushing the movable plate 5010 forward along the fixed rod 5012, the top rod 5011 on the movable plate 5010 is inserted into the filter hole 503 to remove the blockage impurities.

[0048] When the electric push rod 504 is reset, spring 1 509 pulls the moving plate 1 506 back down, push rod 1 507 exits the filter hole 1 502, spring 2 5013 pulls the moving plate 2 5010 back down, push rod 2 5011 exits the filter hole 2 503, and the cleaning and reset is completed.

[0049] Meanwhile, a float plate 603 is installed inside the collection tank 6, which floats on the surface of the liquid. When the liquid level in the collection tank 6 increases, the float plate 603 floats up, causing the sliding block 602 connected to it to slide upward along the guide frame 601. The vertical rod 604 at the upper end of the sliding block 602 then rises accordingly, eventually lifting the lifting block 605 to move upward in sync. When the liquid level rises to near the upper limit of the capacity of the collection tank 6, the lifting block 605 moves upward and touches the start switch 607 fixed on the mounting plate 606, thereby activating the alarm 7, reminding the staff to deal with the overflow liquid in the collection tank 6 in time, avoiding liquid overflow, realizing active control of the overflow of the collection tank 6, and preventing environmental pollution and material loss.
