Description

Technical Field

[0001] The utility model relates to the technical field of bentonite processing, in particular to a bentonite sodium modification device. Background Art

[0002] Methods for sodiumization of calcium bentonite include suspension, dry mixing, wet stacking, and wet extrusion. Common sodiumization agents include soda ash and caustic soda. The mechanism of action is to exchange the calcium cations between the montmorillonite interlayers through an ion exchange reaction (ion exchange adsorption), resulting in a positive charge deficit that is neutralized by exchangeable cations adsorbed on the outer surface of the crystals and between the interlayers.

[0003] In the dry mixing method, soda ash is placed in a mixing box and thoroughly stirred with bentonite for modification. However, when all the soda ash is added to the bentonite at once, a diaphragm is formed on the surface of the bentonite that comes into contact with the soda ash first, affecting the subsequent mixing and modification. In addition, the existing single rotation stirring and mixing efficiency is not high.

[0004] Therefore, it is necessary to provide a new bentonite sodium modification device to solve the above technical problems. Utility Model Content

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0030] See also Figures 1 to 4 The present invention provides a sodium bentonite modification device, which comprises:

[0031] A workbench 1, wherein a discharge chute 101 is provided in the middle of the workbench 1;

[0032] There are two sets of linear guide rails 11, which are installed on the workbench 1 and symmetrically distributed based on the discharge chute 101;

[0033] There are two groups of sliding frames 2. The two groups of sliding frames 2 are respectively slidably mounted on two groups of linear guide rails 11, and the bottom ends of the two groups of sliding frames 2 are installed with connecting arms 3. The top ends of the two groups of sliding frames 2 are installed with raw material boxes 5. A partition assembly 51 is provided in the raw material box 5. A mixing drum 6 is installed in the middle of the two groups of sliding frames 2. A discharge port is provided at the bottom end of the mixing drum 6. A transfer box 52 for material guide communication is provided between the raw material box 5 and the mixing drum 6. An electric telescopic rod 31 is symmetrically mounted on the connecting arm 3. The telescopic end of the electric telescopic rod 31 is installed with a sealing plate 61 that seals the discharge port at the bottom end of the mixing drum 6.

[0034] A lead screw 4 is rotatably mounted in the middle of the workbench 1, and a transmission block 41 is threadedly mounted on the lead screw 4. The transmission block 41 is fixedly connected to the middle of the bottom end of the connecting arm 3. A servo motor 42 is mounted on the workbench 1 to drive the lead screw 4 to rotate;

[0035] There are two groups of support frames 7, which are symmetrically mounted on the workbench 1. The upper rack plate 71 and the lower rack plate 72 are respectively mounted on the two groups of support frames 7;

[0036] The unloading mechanism 8 is provided in the discharge port of the raw material box 5, and the unloading mechanism 8 is in transmission cooperation with the upper rack plate 71;

[0037] The stirring mechanism 9 is disposed in the stirring drum 6 , and the stirring mechanism 9 is in transmission cooperation with the lower rack plate 72 .

[0038] The partition assembly 51 includes a screw 511, which is rotatably mounted on the top of the raw material box 5. A partition plate 512 is threadedly mounted on the screw 511. The partition plate 512 is slidably engaged with the inner arm of the raw material box 5. One end of the screw 511 passes through the raw material box 5 and is mounted with a handwheel 513.

[0039] The transfer box 52 is higher at both ends and lower in the middle, and a through hole 501 communicating with the mixing drum 6 is opened in the middle of the transfer box 52 .

[0040] It should be noted that: when in use, the screw 511 is driven to rotate by turning the handwheel 513, and the screw 511 drives the partition plate 512 to move in the raw material box 5, thereby dividing the raw material box 5 into two parts. The volume ratio of the partition is adjusted according to the dosage ratio of soda ash. After the bentonite and soda ash are placed in the raw material box 5 respectively, the servo motor 42 is started to drive the screw 4 to rotate, so that when the screw 4 rotates, the connecting arm 3 is driven by the transmission block 41 to drive the sliding frame 2 to slide along the linear guide rail 11. When sliding, the servo motor 42 is controlled to rotate alternately forward and reverse, thereby driving the sliding frame 2 to slide back and forth. When sliding, the upper rack plate 71 and the lower rack plate 72 are used to drive the unloading mechanism 8 and the stirring mechanism 9 to unload and stir synchronously, so that the raw materials in the raw material box 5 are introduced into the mixing drum 6 through the transfer box 52, so that the sodium-modified mixing and stirring are more uniform and efficient.

[0041] In the embodiments of the present invention, please refer to Figure 1 and Figure 2 A sealing cover 53 is engaged at the top of the raw material box 5 .

[0042] It should be noted that after the soda ash and bentonite raw materials are placed in the raw material box 5, the sealing cover 53 is tightly closed to prevent the raw materials from splashing when the materials are unloaded.

[0043] In the embodiments of the present invention, please refer to Figure 1 and Figure 4 The unloading mechanism 8 includes a shaft rod 81, which is rotatably mounted on two sets of sliding frames 2, and both ends of the shaft rod 81 pass through the sliding frames 2 and are equipped with gears 82, which are engaged with the upper rack plate 71. The shaft rod 81 extends into the raw material box 5 and is equipped with a unloading impeller 83, and the outer wall of the unloading impeller 83 slides with the inner wall of the unloading end of the raw material box 5.

[0044] It should be noted that when the unloading mechanism 8 is in use, when the sliding frame 2 slides along the linear guide rail 11, the gear 1 82 engages with the upper rack plate 71, thereby driving the shaft 1 81 to rotate, and the shaft 1 81 drives the unloading impeller 83 to rotate, thereby unloading synchronously during sliding.

[0045] In the embodiments of the present invention, please refer to Figure 1 and Figure 4 The stirring mechanism 9 includes a second shaft 91, which is rotatably mounted in the mixing drum 6, and two ends of the second shaft 91 pass through the sliding frame 2 and are equipped with a second gear 92, which is engaged with the lower rack plate 72. The second shaft 91 extends into the side wall of the mixing drum 6 and is equipped with a wheel frame 93. The outer wall of the wheel frame 93 is equipped with a scraper 94, and the inner wall of the scraper 94 is equipped with a plurality of stirring rods 95;

[0046] The outer wall of the scraper 94 is slidably fitted with the inner wall of the mixing drum 6 .

[0047] It should be noted that: similarly, when the sliding frame 2 moves, the gear 2 92 engages with the lower rack plate 72, thereby driving the shaft 2 91 to rotate. The rotation of the shaft 2 91 starts several wheel frames 93 to rotate synchronously. When the wheel frames 93 rotate, they drive the scraper 94 and the stirring rod 95 to stir in the mixing drum 6, so that the soda ash and bentonite are fully mixed, and the mixing and stirring are uniform and efficient.

[0048] The working principle of the bentonite sodium modification device provided by the utility model is as follows:

[0049] When in use, the screw 511 is driven to rotate by rotating the hand wheel 513, and the screw 511 drives the partition plate 512 to move in the raw material box 5, thereby dividing the raw material box 5 into two parts. The volume ratio of the partition is adjusted according to the dosage ratio of soda ash. After the bentonite and soda ash are placed in the raw material box 5 respectively, the servo motor 42 is started to drive the screw 4 to rotate, so that when the screw 4 rotates, the connecting arm 3 is driven by the transmission block 41 to drive the slide 2 to slide along the linear guide rail 11. When sliding, the servo motor 42 is controlled to rotate forward and reverse alternately, thereby driving the slide 2 to slide back and forth. When the slide 2 slides along the linear guide rail 11, the gear One 82 is engaged with the upper rack plate 71, thereby driving the shaft rod one 81 to rotate, and the shaft rod one 81 drives the unloading impeller 83 to rotate, so that the material is unloaded synchronously during sliding, and the raw material in the raw material box 5 falls into the transfer box 52 during sliding, and then falls into the mixing drum 6 from the through hole 501 of the transfer box 52. Then, when the sliding frame 2 moves, the gear two 92 is engaged with the lower rack plate 72, thereby driving the shaft rod two 91 to rotate. The rotation of the shaft rod two 91 starts several wheel frames 93 to rotate synchronously. When the wheel frames 93 rotate, they drive the scraper 94 and the stirring rod 95 to stir in the mixing drum 6, so that the soda ash and bentonite are fully mixed, and the mixing and stirring are uniform and efficient.

[0050] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.
