Description

Technical Field

[0001] The utility model relates to the field of thickeners, and in particular to a feeding device for a thickener. Background Art

[0002] Thickener is a solid-liquid separation device based on gravity sedimentation. It is usually a cylindrical shallow tank with a conical bottom made of concrete, wood or metal welded plates as structural materials. It can concentrate slurry with a solid weight of 10% to 20% into an underflow slurry with a solid content of 45% to 55% through gravity sedimentation. With the help of a slow-running (1 / 3 to 1 / 5 r / min) rake installed in the thickener, the thickened underflow slurry is discharged from the underflow port at the bottom of the thickener.

[0003] However, due to the structural arrangement between the feed pipe and the flocculant addition pipe of the existing thickener, during the feeding process, some materials in the feed pipe cannot be fully dispersed when in contact with the flocculant, thereby failing to achieve a sufficient mixing effect.

[0004] Therefore, it is very necessary to invent a feeding device for a thickener. Utility Model Content

[0023] The flocculant feeding pipe includes an inner pipe 2 and an outer pipe 3, and the inner pipe 2 and the outer pipe 3 are fixedly connected, and a U-shaped arrangement is adopted between the inner pipe 2 and the outer pipe 3, and the inner pipe 2 and the outer pipe 3 are connected; the inner pipe 2 is fixedly installed in the transverse pipe inside the L-shaped material pipe 1 through the corner of the L-shaped material pipe 1, and the inner pipe 2 is coaxial with the transverse pipe of the L-shaped material pipe 1, and the arrangement of the inner pipe 2 allows the flocculant to flow out from the center of the L-shaped material pipe 1; the outer pipe 3 is located above the outside of the L-shaped material pipe 1, and the length of the outer pipe 3 is the same as the length of the transverse pipe of the L-shaped material pipe 1, and the outer pipe 3 is arranged in parallel with the transverse pipe of the L-shaped material pipe 1, and is arranged so as to be connected to an external flocculant feeding device;

[0024] A plurality of double-conical tubes 6 are evenly and fixedly installed on the inner tube 2. Through the setting of the double-conical tubes 6, the material inside the L-shaped material tube 1 can be evenly dispersed during the contact with the material inside the L-shaped material tube 1, so that the material can be fully contacted and mixed with the flocculant sprayed from the atomizing nozzle, and the resistance to the flow of the material can be reduced. Each of the double-conical tubes 6 is connected in series with the inner tube 2, and the double-conical tubes 6 are in the horizontal tube of the L-shaped material tube 1, and the double-conical tubes 6 are coaxial with the inner tube 2; a plurality of liquid outlet holes 7 are evenly distributed on the circumference of the double-conical tube 6 facing one end of the vertical tube of the L-shaped material tube 1, and the liquid outlet holes 7 are connected with the inner tube 2. Through the setting of the liquid outlet holes 7 and the double-conical tubes 6, the material inside the L-shaped material tube 1 can be prevented from impacting the liquid outlet holes 7, thereby protecting the atomizing nozzle.

[0025] An integrated frustum head 5 is provided at one end of the inner tube 2 which is inside the horizontal tube of the L-shaped material tube 1. Through the setting of the frustum head 5, during the process in which the material inside the L-shaped material tube 1 contacts the inner tube 2, the material inside the L-shaped material tube 1 can be evenly dispersed, thereby reducing obstruction to the material and reducing the impact of the material inside the L-shaped material tube 1 on the end of the inner tube 2.

[0026] An atomizing nozzle is fixedly installed inside the liquid outlet 7 so as to allow the flocculant to contact and mix evenly with the material in the L-shaped material pipe 1 .

[0027] A bracket 4 is fixedly installed between the outer tube 3 and the transverse tube of the L-shaped material pipe 1; ring sleeves corresponding to the outer tube 3 and the transverse tube of the L-shaped material pipe 1 are fixedly installed at both ends of the bracket 4, and the ring sleeves are fixed on the corresponding outer tube 3 and the transverse tube of the L-shaped material pipe 1; through the setting of the bracket 4, the stability between the outer tube 3 and the L-shaped material pipe 1 can be ensured.

[0028] In this embodiment, when in use, one end of the outer tube 3 is connected to the external flocculant feeding device, and then one end of the horizontal tube of the L-shaped material pipe 1 is connected to the degassing tank of the thickener, and one end of the vertical tube of the L-shaped material pipe 1 is connected to the central feeding barrel of the thickener;

In this way, during the contact between the double cone tube 6 and the material, the material will be dispersed so that the material can be fully mixed and contacted with the flocculant sprayed from the atomizing nozzle, and finally enter the central feeding barrel of the thickener to complete the feeding.
