Description

Technical Field

[0001] The utility model relates to the technical field of carbon slurry adsorption beneficiation, in particular to a double-impeller leaching stirring tank rotary carbon separation device. Background Art

[0002] The carbon separator in the existing process is a cylindrical screen, the end of which is bolted to the overflow port of the mixing tank through a flange. The slurry enters the body of the cylindrical screen through the mesh of the carbon separator, and then flows into the overflow port through the end. The activated carbon is blocked by the mesh in the mixing tank to continue to adsorb gold particles. This method is simple and practical in design, but in actual production, the mesh will be blocked due to the adhesive properties of the slurry and a small amount of debris. The mesh is a 30-mesh fine screen, which reduces the overflow of slurry and causes the liquid level to rise. The operator must be aware of the problem at any time. Generally, vibration and knocking are used to remove debris from the net, which increases manual maintenance. Utility Model Content

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0029] Reference Figure 1-10 The utility model discloses a rotary carbon separation device for a double-impeller leaching stirring tank, comprising a rotating screen drum 1, one end of which is connected to a slurry outlet pipe 5, a sealing mechanism 2 is arranged outside the slurry outlet pipe 5, and the slurry outlet pipe 5 is rotatably installed at the slurry outlet of the stirring tank through the sealing mechanism 2.

[0030] The rotating screen drum 1 includes a cylindrical frame located inside, with circular plates on both end circular surfaces of the cylindrical frame, a screen installed on the circumferential surface of the cylindrical frame, and a slurry outlet pipe 5 is coaxially arranged with the rotating screen drum 1. When cleaning is required, the screen can be directly flushed with clean water to reduce the difficulty of cleaning.

[0031] In the present application, the rotating screen drum 1 is driven by an external driving source 8, which is a motor. A gear ring 6 is installed at one end of the rotating screen drum 1 close to the sealing mechanism 2, or a sprocket 7 is installed on the outside of the slurry discharge pipe 5, and a driving gear is installed at the working end of the motor. The driving gear meshes with the gear ring 6 to drive the rotating screen drum 1 to rotate, or a driving sprocket is installed at the working end of the motor, and the driving sprocket and the sprocket 7 are connected by a chain, which can also drive the rotating screen drum 1 to rotate.

[0032] The sealing mechanism 2 comprises a sealing box 201 , and a detachable sealing plate 202 is arranged inside the sealing box 201 . The sealing plate 202 is wrapped around the outside of the pulp outlet pipe 5 along the circumferential direction.

[0033] The outside of the slurry outlet pipe 5 is mirror-finished, and the sealing plate 202 can be made of brake band, which is cheap and has good wear resistance.

[0034] When installing the sealing mechanism 2, specifically, the sealing box 201 is fixedly connected to the side wall of the stirring tank, and then the slurry outlet pipe 5 and the sealing plate 202 are rotationally sealed to prevent slurry leakage.

[0035] A clamping groove plate 205 is disposed inside the sealing box 201 , and a fixing plate 204 matched with the clamping groove plate 205 is disposed outside the sealing plate 202 . The fixing plate 204 is slidably connected to the clamping groove plate 205 .

[0036] The groove plate 205 is fixedly connected to the inner wall of the sealing box 201, the inner side of the groove plate 205 is a groove, the fixed plate 204 is located in the groove, the gap between the fixed plate 204 and the groove plate 205 is sealed, and the sealing plate 202 is detachably installed in the sealing box 201 through the sliding sealing connection between the fixed plate 204 and the groove plate 205. Since the sealing plate 202 and the outer wall of the slurry outlet pipe 5 are in sliding friction contact, the sealing plate 202 itself is a wearing part, and the detachable connection facilitates the replacement of the sealing plate 202.

[0037] The sealing box 201 and the fixing plate 204 are both square, and the fixing plate 204 is square outside and round inside.

[0038] A hoop 203 is provided between the sealing plate 202 and the fixing plate 204 . The outer wall of the hoop 203 is connected to the fixing plate 204 , and the inner wall of the hoop 203 is connected to the outer wall of the sealing plate 202 .

[0039] The sealing plate 202 and the hoop 203 are both annular. The hoop 203 is mainly a steel hoop, which supports the sealing plate 202 and is used to press the sealing plate 202 so that the sealing plate 202 is in close contact with the slurry outlet pipe 5.

[0040] The circular hoop 203 and the sealing plate 202 are fixed by rivets, and the circular hoop 203 and the fixing plate 204 are fixed by welding.

[0041] A partition plate 501 is fixedly connected to the circumferential surface of the slurry outlet pipe 5, and the partition plate 501 is also in a circular ring shape. A sealing groove 502 is formed between the two partition plates 501. In the present application, there are multiple sealing grooves 502, and the same set of sealing plates 202, circular hoops 203 and fixed plates 204 are all located in the same sealing groove 502. The sealing plate 202 is in close contact with the bottom of the sealing groove 502, and the bottom of the sealing groove 502 is mirror-finished to reduce friction. A labyrinth groove 9 with a Z-shaped cross-section is formed between the partition plate 501 and the clamping groove plate 205, and multiple sets of sealing plates 202 are installed in the labyrinth groove 9 to improve the sealing effect of the sealing mechanism 2.

[0042] There are two sealing boxes 201 , sealing plates 202 , circular hoops 203 , fixing plates 204 , and clamping groove plates 205 . The two sealing boxes 201 , sealing plates 202 , circular hoops 203 , fixing plates 204 , and clamping groove plates 205 are symmetrical about the radial axis of the slurry outlet pipe 5 .

[0043] This structure can reduce the difficulty of installing the sealing mechanism 2. Specifically, during installation, the sealing box 201 of the lower part can be welded to the slurry outlet of the mixing tank first, and then the sealing plate 202, the circular hoop 203, and the fixed plate 204 of the lower part can be installed into the sealing box 201, and then the slurry outlet pipe 5 of the rotating screen drum 1 can be directly placed into the sealing plate 202, and finally the sealing box 201, the sealing plate 202, the circular hoop 203, the fixed plate 204, and the clamping groove plate 205 of the upper part can be buckled together with the sealing box 201, the sealing plate 202, the circular hoop 203, the fixed plate 204, and the clamping groove plate 205 of the lower part.

[0044] The sides of the two sealing boxes 201 are both provided with screw-connecting ear plates 206 .

[0045] A through hole is processed on the screw-joined ear plate 206 . When the two sealed boxes 201 are buckled together, bolts are used to connect the two sealed boxes 201 through the screw-joined ear plate 206 .

[0046] In the present application, an installation box 3 can also be installed on the outside of the sealing mechanism 2. The installation box 3 is a box body structure with openings on the top and one end, and a disassembly groove 301 is processed on the other end of the installation box 3. The disassembly groove 301 is a U-shaped groove with an opening on the top, and the shape of the slurry outlet of the double-impeller leaching stirring tank is also a U-shaped groove with a similar structure to the disassembly groove 301. When in use, the two U-shaped grooves on the installation box 3 and the stirring tank are matched, and the sealing box 201 of the lower half is welded and fixed to the bottom of the U-shaped groove.

[0047] In the present application, the slurry level in the mixing tank generally reaches near the circumferential center line of the rotating screen drum 1, that is, during the operation of the rotating screen drum 1, its upper half leaks out of the slurry surface. The structure of the disassembly groove 301 facilitates the lifting of the rotating screen drum 1 and the sealing mechanism 2, thereby facilitating the replacement of the sealing plate 202.

[0048] A tail support mechanism 4 is provided on one end of the rotary screen drum 1 away from the sealing mechanism 2 , one end of the tail support mechanism 4 is rotatably connected to the rotating shaft of the rotary screen drum 1 , and the other end is fixedly connected to the stirring tank.

[0049] The tail support mechanism 4 is mainly rotatably connected to the rotating shaft of the rotating screen drum 1 through structures such as bearings or rings, wherein the bearings are sealed and installed. The tail support mechanism 4 is a rotating support mechanism at both ends of the circumferential center line direction of the rotating screen drum 1, which facilitates the smooth operation of the rotating screen drum 1.

[0050] A watering mechanism is arranged above the rotary screen drum 1 .

[0051] The watering mechanism sprays water on the screen of the rotating screen drum 1. When slurry particles and sundries and impurities stick to the screen and leak out of the slurry liquid surface as the screen rotates, the watering mechanism sprays water on the surface of the screen to effectively wash away these particles and impurities, thereby further reducing the particles and impurities on the screen, reducing blockages and reducing manual maintenance work.

[0052] Working principle: When in use, the device is installed at the slurry outlet of the double-impeller leaching and stirring tank. The rotating screen drum 1 and the slurry outlet pipe 5 rotate synchronously. The slurry enters the rotating screen drum 1 through the sieve holes of the rotating screen drum 1, and then flows out through the slurry outlet pipe 5, while the activated carbon particles are blocked in the stirring tank by the sieve holes.

[0053] When the sealing plate 202 needs to be replaced, the upper part of the sealing mechanism 2 is first removed, and then the rotary screen drum 1 is hoisted. After the sealing plate 202 is replaced, the rotary screen drum 1 can be reinstalled.
