Description

An automatic flocculation sedimentation diversion device for a concentrator Technical Field

[0001] This invention relates to the field of thickener technology, specifically to an automatic flocculation sedimentation and diversion device for a thickener. Background Technology

[0002] Thickeners are widely used in industries such as metallurgy, chemical industry, coal, non-metallic mineral processing, and environmental protection. High-efficiency thickeners are not actually simple sedimentation equipment, but a new type of dewatering equipment that combines the filtration characteristics of mud layers.

[0003] In the prior art, Chinese utility model publication CN209596620U discloses a concentrator for preparing bamboo sap, belonging to the technical field of concentrators for bamboo sap preparation. The concentrator includes a concentrator body, an electric motor mounted on the upper end of the concentrator body, the output end of the electric motor penetrating the inner wall of the concentrator body and fixedly connected to a receiving rod, multiple stirring rods fixedly connected to the outer end of the receiving rod, and a flow guide located above the multiple stirring rods. The flow guide includes a flow guide plate and an annular mounting plate, the annular mounting plate contacting the multiple stirring rods located on the uppermost side, and multiple compression springs fixedly connected between the flow guide plate and the annular mounting plate. The multiple compression springs are evenly distributed in a ring on the surface of the flow guide plate and the annular mounting plate. The flow guide plate is slidably connected to the receiving rod, which can reduce the falling speed of raw materials and flocculants entering the concentrator body, making them less likely to affect particles that have already settled or are settling, thus improving the concentration efficiency.

[0004] In the above technology, raw materials and flocculants are poured into the thickener body through the feed pipe and flocculant pipe respectively. The motor drives the receiving rod and the stirring rod to stir the two, so that they can react fully. However, the raw materials and flocculants may clump together during storage. When the clumped raw materials and flocculants are directly added into the thickener body, they are difficult to mix fully. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic flocculation and sedimentation diversion device for a thickener to solve the problem of difficulty in mixing agglomerated raw materials and flocculants.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0018] Preferably, a through hole is provided between the first storage slot and the third storage slot, and a matching pull rope is provided inside the through hole. The two ends of the pull rope are respectively connected to the extrusion plate and the top block.

[0019] The elastic force of the third elastic element is greater than that of the second elastic element.

[0020] Preferably, a matching limiting plate is fixedly provided on the inner wall of the crushing cylinder at the end position of the crushing rod. Multiple sets of the limiting plates are provided, and the multiple sets of the limiting plates are evenly spaced in a circumferential state.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] This invention filters raw materials and flocculants through a filter screen inside the crushing cylinder. While filtering, the second rotating shaft drives the crushing rod to rotate, concentrating the agglomerated raw materials and flocculants below the extrusion plate.

During rotation, it can clean the filter screen and prevent raw materials and flocculants from clogging the filter screen pores. At the same time, the rotating turntable can quantitatively feed raw materials or flocculants into the thickener body through the quantitative holes. Attached Figure Description

A matching cleaning plate 21 is inserted into the second storage groove 24, and a first elastic member 25 is provided between the cleaning plate 21 and the second storage groove 24.

[0053] The crushing rod 13 has a third storage groove 27 on one side wall facing the rotation direction of the second rotating shaft 15. A matching extrusion plate 26 is inserted into the third storage groove 27, and multiple sets of spaced second elastic members 28 are provided between the extrusion plate 26 and the third storage groove 27.

[0058] The raw materials and flocculants are filtered through the filter screen inside the crushing cylinder 5. While filtering, the second rotating shaft 15 drives the crushing rod 13 to rotate, concentrating the agglomerated raw materials and flocculants below the extrusion plate 26. When the elastically set top block 22 collides with the limiting plate 12, the elastically set extrusion plate 26 will no longer be limited by the tension of the pull rope 30 and will move downward, thereby crushing the agglomerated raw materials and flocculants. The cleaning plate 21 is designed to always be in contact with the surface of the filter screen through the first elastic element 25. During rotation, it can clean the filter screen and prevent the raw materials and flocculants from clogging the filter screen apertures.

[0059] Example 3:

[0060] As shown in Figures 3 and 4, the automatic flocculation sedimentation and diversion device for the thickener disclosed in Embodiment 3 of the present invention has a structure that is basically the same as that in Embodiment 2, except that:

[0061] The bottom of the crushing cylinder 5 is provided with a connecting pipe 20, and a fixed cylinder 6 is fixedly provided at one end of the connecting pipe 20 away from the crushing cylinder 5. A relief groove 16 is provided inside the fixed cylinder 6, and the crushing cylinder 5 is connected to the relief groove 16 through the connecting pipe 20.

[0062] The interior of the relief groove 16 is provided with a matching turntable 17, and the turntable 17 is provided with a metering hole 18 at the position corresponding to the connecting pipe 20. The bottom of the relief groove 16 is provided with a matching discharge port 19 at the position corresponding to the metering hole 18.

[0063] A second motor 11 is fixedly installed at the center of one side wall of the fixed cylinder 6, and the output end of the second motor 11 is fixedly connected to the side wall of the turntable 17.

[0064] The filtered raw material will be stored inside the connecting pipe 20, and the rotating turntable 17 can drive the metering hole 18 to rotate, storing the raw material and flocculant inside the connecting pipe 20 inside the metering hole 18. Then, through the cooperation of the metering hole 18, the raw material or flocculant is metered into the thickener body 1, so that it can automatically flocculate and settle.

[0065] Specifically, the solution is as follows: raw materials and flocculants are placed inside the thickener body 1 through the raw material inlet 3 and the flocculant inlet 4. The raw materials and flocculants are discharged into the connecting pipe 20 through the filter of the crushing cylinder 5, while the agglomerated raw materials and flocculants are stored inside the crushing cylinder 5. At this time, the third motor 14 is started, and the third motor 14 drives the second rotating shaft 15 to rotate. During the rotation of the second rotating shaft 15, the crushing rod 13 is driven to rotate, concentrating the agglomerated raw materials and flocculants below the extrusion plate 26. When the elastically set top block 22 collides with the limiting plate 12, the elastically set extrusion plate 26 will no longer be limited by the tension of the pull rope 30 and will move downward, thereby realizing the crushing and crushing of the agglomerated raw materials and flocculants. In addition, the cleaning plate 21 can always be in contact with the surface of the filter screen through the first elastic element 25. During the rotation, the filter screen can be cleaned to prevent the raw materials and flocculants from clogging the filter screen aperture.

[0066] Then the second motor 11 is started, and the second motor 11 drives the turntable 17 to rotate. When the metering hole 18 coincides with the connecting pipe 20, the flocculant or raw material enters the interior of the metering hole 18. When the metering hole 18 rotates to coincide with the discharge port 19, the raw material or flocculant falls into the surface of the guide plate 8 and the interior of the guide groove 9. Through the guiding cooperation of the rotating first rotating shaft 7, it is evenly sprinkled into the interior of the thickener body 1, so that the interior of the thickener body 1 automatically flocculates and settles.
