AI Technical Summary
The existing automatic sludge discharge device at the bottom of the thickener cannot adjust the feeding speed, resulting in low discharge stability when the sludge volume is large, which can easily lead to pipeline blockage and affect the thickener's processing efficiency.
By adopting a photoelectric sensor and cylinder linkage design, the sludge is dynamically matched with the sludge accumulation height. Combined with the pressure sensor and cylinder control of the baffle plate and pressing plate, the sludge is stably discharged, preventing blockage.
It improves the emission stability and treatment efficiency of the thickener under high load conditions, prevents pipeline blockage, and ensures the normal operation of the equipment.

Technical Field
[0001] This utility model relates to the field of automatic discharge technology for bottom sludge from thickeners, and in particular to an automatic discharge device for bottom sludge from thickeners. Background Technology
[0002] A thickener introduces a suspension of liquid containing solid particles, and uses gravity to cause the heavier solid particles to settle in the settling zone, while the lighter water is discharged through an overflow or outlet. As the settling process continues, the concentrated solid particles form a sludge layer at the bottom of the thickener. This sludge needs to be discharged periodically or automatically to maintain the normal operation of the thickener.
[0003] The existing automatic sludge discharge device at the bottom of the thickener cannot adjust the feeding speed. When there is a lot of sludge, the discharge stability is not high, which can easily cause blockage of the discharge pipeline and affect the thickener's processing efficiency. Summary of the Invention
[0004] In order to overcome the shortcomings of existing automatic sludge discharge devices at the bottom of thickeners, which are prone to pipe blockage when the sludge volume is large due to the inability to adjust the feeding speed, thus affecting the thickener's processing efficiency, this utility model can provide an automatic sludge discharge device for thickeners.

A baffle plate is fitted inside the other end of each positioning seat. The rear end of the baffle plate is rotatably connected to the inner wall of the feeding hopper. A control panel is located on the front side of the processing box. A photoelectric sensor is located on the inner wall of the feeding hopper. The photoelectric sensor is electrically connected to the control panel.
[0006] Furthermore, it also includes a connecting plate, a second cylinder, a pressing plate, a pad, and a grid plate. The connecting plate is located inside the processing box, and the second cylinder is located in the middle of the connecting plate.

Detailed Implementation
[0017] 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.
[0018] An automatic discharge device for thickener sludge, such as Figures 1-4As shown, the system includes a processing box 1, a feeding hopper 2, a first cylinder 3, a moving column 4, a connecting rod 5, a positioning seat 6, a baffle plate 7, a photoelectric sensor 16, and a control panel 17. The feeding hopper 2 is located on the inner side of the top of the processing box 1. The first cylinder 3 is located on the front side of the feeding hopper 2. The moving column 4 is connected to the telescopic rod of the first cylinder 3. Two connecting rods 5 are rotatably connected to the outer side of the moving column 4. Two positioning seats 6 are located on the front side of the feeding hopper 2. The end of the connecting rod 5 away from the moving column 4 is hinged to the positioning seat 6. At one end, baffle plates 7 are fitted inside the other end of the two positioning seats 6. The bottom of the two baffle plates 7 is opened with through grooves 15. When the two baffle plates 7 are closed, the two through grooves 7 are aligned to form a continuous channel, allowing a small amount of sludge to pass through. The rear end of the baffle plates 7 is rotatably connected to the inner wall of the feeding hopper 2. A control panel 17 is provided on the front side of the processing box 1. A photoelectric sensor 16 is provided on the inner wall of the feeding hopper 2. The photoelectric sensor 16 is electrically connected to the control panel 17. A feed pipe 19 is provided on the top of the feeding hopper 2.
[0019] like Figure 2 As shown, it also includes a connecting plate 9, a second cylinder 10, a pressing plate 11, a pad 12, and a grid plate 13. The connecting plate 9 is provided inside the treatment box 1. The second cylinder 10 is located in the upper middle part of the connecting plate 9. The pressing plate 11 is connected to the telescopic rod of the second cylinder 10. The pad 12 is provided inside the bottom of the treatment box 1. The pad 12 is located directly below the second cylinder 10. A through hole is opened on the left side of the treatment box 1. The grid plate 13 is provided in the through hole. A drain pipe 18 is provided on the left side of the grid plate 13. A pressure sensor is connected between the treatment box 1 and the pad 12. The pressure sensor is electrically connected to the control panel 17. The pressure sensor continuously monitors the pressure on the top of the pad 12. When the pressure value exceeds the preset value, the pressure sensor controls the second cylinder 10 to start through the control panel 17. The second cylinder 10 drives the pressing plate 11 to move up and down reciprocally to crush larger or clumped sludge, so that the sludge is discharged through the grid plate 13 from the drain pipe 18, preventing sludge blockage.
[0020] like Figure 4 As shown, it also includes a guide rail 14, and the front side of the feeding hopper 2 is provided with a guide rail 14 for the linear movement of the moving column 4.
[0021] like Figure 2 As shown, it also includes an inclined block 8. An inclined block 8 is provided on the inner side of the bottom of the treatment box 1. The inclined block 8 is located below the feeding hopper 2. The inclined block 8 is used to guide the sludge falling from the feeding hopper 2 to the bottom of the treatment box 1.
[0022] Sludge is fed into the hopper 2 through the feed pipe 19. At this time, the baffle plate 7 is closed. The sludge will first accumulate on the top of the baffle plate 7, and a small amount of sludge will fall into the processing box 1 through the through groove 15 at the bottom of the baffle plate 7. The height of the sludge will continue to rise during the accumulation. When the height of the sludge rises to the same height as the photoelectric sensor 16, the photoelectric sensor 16 controls the first cylinder 3 to retract through the control panel 17. The extension rod of the first cylinder 3 drives the moving column 4 to move upward, thereby driving the positioning seat 6 to rotate through the connecting rod 5, thereby driving the baffle plate 7 to rotate to open the baffle plate 7 and let the sludge accumulated on the top of the baffle plate 7 fall down. After a preset time, the control panel 17 controls the first cylinder 3 to extend to close the baffle plate 7 again.
[0023] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
