Description

Technical Field

[0001] The invention relates to the field of sodium bentonite, and more specifically to a sodium bentonite modification treatment device. Background Art

[0002] Bentonite is also called bentonite, soap clay or bentonite. Bentonite is a non-metallic mineral with montmorillonite as the main mineral component. The montmorillonite structure is a 2:1 type crystal structure composed of two silicon oxygen tetrahedrons sandwiching a layer of aluminum oxygen octahedron. Due to its special properties, such as swelling, adhesion, adsorption, catalysis, thixotropy, suspension and cation exchange, it is widely used in various industrial fields.

[0003] The process of sodiumization of bentonite can be divided into two categories: dry method and wet method. However, the traditional dry sodiumization cannot effectively carry out ion exchange reaction between calcium ions in bentonite and sodium ions in sodium salt, so the sodiumization effect is poor. The Chinese patent with publication number CN110422852B discloses a sodium bentonite device, wherein bentonite is poured into a feed shell, sodium salt is placed on the lower end wall of the base space, a first motor is started, and a first rolling roller and a second rolling roller are driven to rotate to crush the bentonite, and at the same time, a first fan is driven to rotate to blow the sodium salt upward, a crushing wheel crushes the crushed bentonite, and at the same time, the centrifugal force of the crushing wheel drives the bentonite fragments to splash around, so that the splashed bentonite fragments and the blown sodium salt contact, thereby playing a pre-mixing role, so as to facilitate subsequent mixing more fully and evenly, but when the device mixes the bentonite and the sodium salt in a two-splashing manner, when the bentonite is mixed and falls, the accumulated bentonite will cover part of the sodium salt, making it impossible to splash, resulting in uneven mixing, and this method has a slow mixing efficiency. Summary of the invention

[0004] The purpose of the present invention is to provide a sodium-modified bentonite treatment device in view of the shortcomings of the prior art. After the bentonite is transported between the cylinder and the fixed cylinder, a push plate pushes the bentonite out while a scraper flattens the bentonite along the surface of the fixed cylinder. Subsequently, the bentonite is stirred by a soil turning component while sodium salt is added thereto, so that the bentonite and the sodium salt are fully contacted and mixed.

[0005] The technical solutions of the present invention are as follows:

[0006] A sodium-modified bentonite treatment device comprises a base, a fixed cylinder is fixedly arranged on the base, a guide assembly and a bulldozer assembly driven by the guide assembly are arranged inside the fixed cylinder, a rotating cylinder is rotatably arranged outside the fixed cylinder, a scraper assembly and a soil turning assembly are arranged on the rotating cylinder, a shell is arranged outside the rotating cylinder, a loading assembly and a unloading assembly are arranged on the shell, the bulldozer assembly is used to push the bentonite into the rotating cylinder with the cooperation of the guide assembly, the scraper assembly is used to scrape the bentonite flat on the surface of the fixed cylinder when it is pushed out, the soil turning assembly is used to stir the bentonite, the loading assembly is used to add sodium salt into the bentonite while stirring the bentonite, and the unloading assembly is used to unload the sodium-modified bentonite.

[0009] Preferably, the scraping assembly comprises a plurality of scrapers fixedly arranged on the inner wall of the rotating cylinder and through holes formed on the scrapers, and the scrapers are arranged as an inclined structure.

[0010] Preferably, the soil turning assembly includes a second motor fixedly mounted on a base, racks fixedly mounted at both ends of a rotating cylinder, a plurality of augers rotatably mounted in the rotating cylinder, and gears fixedly mounted at both ends of the augers, wherein the gears are meshed with the racks, and the rotating cylinder is fixedly connected to an output shaft of the second motor.

[0011] As a preference, the feeding assembly comprises a leakage hole opened along the circumferential direction of the shell, a discharge port opened on the rotating cylinder and a salt storage box arranged on the shell, and the leakage hole cooperates with the discharge port.

[0015] The beneficial effects of the present invention are:

[0016] 1. The present invention is provided with a guide assembly and a bulldozer assembly. After the delivery pipe delivers bentonite to the fixed cylinder and the cylinder body and fills them, the first motor drives the boss to rotate. During the rotation of the boss, the push rod pushes up the push plate when passing through the protrusion, and the baffle slides into the fixed cylinder. The push plate drives the bentonite above the push plate to move toward the opening, so that the bentonite is smoothly pushed out.

The rotating cylinder drives the scraper to pass through the opening, drives the bentonite to move along the upper surface of the fixed cylinder and the bentonite is scraped on its surface. The gear rotates under the action of the rack while revolving. The gear drives the auger to rotate. The auger can stir the bentonite when passing through the bentonite. While stirring, the discharge port and the leakage hole just correspond to each other. Sodium salt falls out of the salt storage box and is evenly sprinkled on the bentonite. After the auger stirs, it is fully and evenly mixed with the bentonite. In addition, the scraper can drive the unmixed bentonite to move and can push the mixed bentonite to the bottom of the rotating cylinder, and it is stirred by other augers to ensure its mixing effect. When the bentonite in the rotating cylinder is fully mixed and reaches a certain amount, the rotating cylinder rotates to the position corresponding to the discharging port and the opening and closing plate. Then the switch controls the opening and closing plate to open, and the bentonite in the rotating cylinder is discharged.

[0018] In summary, the present invention has the advantages of good sodiumization effect and uniform mixing, and is suitable for the field of bentonite sodiumization. BRIEF DESCRIPTION OF THE DRAWINGS

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0032] like Figures 1 to 8 As shown, a sodium-modified bentonite treatment device comprises a base 1, on which a fixed cylinder 2 is fixedly arranged, a guide assembly 3 and a bulldozer assembly 4 driven by the guide assembly 3 are arranged inside the fixed cylinder 2, a rotating cylinder 5 is rotatably arranged outside the fixed cylinder 2, a scraper assembly 6 and a tiller assembly 7 are arranged on the rotating cylinder 5, a shell 8 is arranged outside the rotating cylinder 5, and a loading assembly 9 and a unloading assembly 10 are arranged on the shell 8, the bulldozer assembly 4 is used to push the bentonite into the rotating cylinder 5 with the cooperation of the guide assembly 3, the scraper assembly 6 is used to scrape the bentonite flat on the surface of the fixed cylinder 2 when it is pushed out, the tiller assembly 7 is used to stir the bentonite, the loading assembly 9 is used to add sodium salt into the bentonite while stirring the bentonite, and the unloading assembly 10 is used to unload the sodium-modified bentonite.

[0033] like Figure 3 As shown, the guide assembly 3 includes a first motor 31 fixedly mounted on the base 1, a guide cylinder 32 fixedly connected to the output shaft of the first motor 31, a boss 33 fixedly arranged along the circumferential direction of the guide cylinder 32, and a guide groove 34 opened on the boss 33.

[0034] like Figure 4 and Figure 7As shown, the bulldozer assembly 4 includes a cylinder 41 fixedly arranged on the base 1, a push rod 42 slidably arranged on the cylinder 41, and a push plate 43 fixedly arranged on the push rod 42. The bottom of the push rod 42 is set to be spherical and matched with the guide groove 34. The push plate 43 is set to be an arc structure and the inner wall is matched with the outer wall of the cylinder 41. An opening 44 is opened on the fixed cylinder 2 and a baffle 21 is slidably arranged on the inner wall of the fixed cylinder 2. The baffle 21 matches the opening 44, and the opening 44 matches the push plate 43. Among them, bentonite conveying pipes are arranged on the cylinder 41 and the rotating cylinder 5. When the bentonite is pushed out, the conveying pipe is automatically filled, so that the bentonite between the cylinder 41 and the rotating cylinder 5 is always in a filled state, and the baffle 21 is slidably arranged on the inner wall of the fixed cylinder 2. The baffle 21 matches the opening 44, and the opening 44 matches the push plate 43. The door 21 is an automatic electric door, and its initial state is at the opening 44, so that the fixed cylinder 2 is a closed space. When the push plate 43 starts to slide, the baffle door 21 automatically slides into the fixed cylinder 2. When in use, the first motor 31 drives the boss 33 to rotate. During the rotation of the boss 33, the push rod 42 pushes up the push plate 43 when it passes through the protrusion, and the baffle door 21 slides into the fixed cylinder 2. The push plate 43 drives the bentonite above the push plate 43 to move toward the opening 44 so that the bentonite can be taken out. When the push rod 42 passes through the groove and drives the push plate 43 to retreat for reset, the baffle door 21 slides out to the opening 44 and closes the opening 44. Subsequently, the delivery pipe delivers the bentonite to between the fixed cylinder 5 and the cylinder body 41 until it is filled.

[0035] like Figure 7 As shown, the scraper assembly 6 includes a plurality of scrapers 61 fixedly arranged on the inner wall of the rotating cylinder 5, and a through hole 62 opened on the scraper 61. The scraper 61 is arranged as an inclined structure. When in use, when the bentonite is pushed out, the rotating cylinder 5 drives the scraper 61 through the opening 44, drives the bentonite to move toward the upper surface of the fixed cylinder 2 and the bentonite is scraped flat on its surface. In addition, the bentonite that falls into the angle between the scraper 61 and the rotating cylinder 5 can fall out through the through hole 62.

[0036] like Figures 5 to 7 As shown, the soil turning assembly 7 includes a second motor 71 fixedly arranged on the base 1, racks 72 fixedly arranged at both ends of the rotating cylinder 5, a plurality of augers 73 rotatably arranged in the rotating cylinder 5, and gears 74 fixedly arranged at both ends of the augers 73. The gears 74 are meshed with the racks 72, and the rotating cylinder 5 is fixedly connected to the output shaft of the second motor 71. When in use, the scraper 61, the augers 73, and the gears 74 rotate along with the rotating cylinder 5. The gears 74 rotate on their own under the action of the racks 72 while revolving. The gears 74 drive the augers 73 to rotate. After the scraper 61 flattens the bentonite, the augers 73 can stir the bentonite when passing through the bentonite. At this time, the push plate 43 pushes the bentonite to the opening 44 again. The latter group of scrapers 61 and augers 73 perform the same work, and when the scraper 61 drives the unmixed bentonite to move, the mixed bentonite can be pushed down to the bottom of the rotating cylinder 5 and stirred by other augers 73 to ensure its mixing effect.

[0037] like Figure 7 As shown, the feeding assembly 9 includes a leakage hole 91 opened along the circumferential direction of the shell 8, a discharge port 92 opened on the rotating cylinder 5, and a salt storage box 93 arranged on the shell 8. The leakage hole 91 cooperates with the discharge port 92. When in use, when the auger 73 stirs the bentonite, the discharge port 92 corresponds to the leakage hole 91, and the sodium salt falls out from the salt storage box 93, is evenly sprinkled on the bentonite, and is fully and evenly mixed with the bentonite after being stirred by the auger 73.

[0038] like Figure 8 As shown, the unloading component 10 includes a unloading port 101 opened on the rotating drum 5 and an opening and closing plate 102 rotatably set on the shell 8, the unloading port 101 cooperates with the opening and closing plate 102, wherein the opening and closing plate 101 is set as an automatic opening and closing structure, and is electrically connected to an external switch. When in use, when the bentonite in the rotating drum 5 is fully mixed and reaches a certain amount, the rotating drum 5 rotates to the position corresponding to the unloading port 101 and the opening and closing plate 102, and then the switch controls the opening and closing plate 102 to open, and the bentonite in the rotating drum 5 is unloaded.

[0039] like Figure 3 As shown, the guide groove 34 is a wave-shaped groove structure, which drives the push plate 43 to move up and down.

[0040] like Figure 7 As shown, a baffle 11 is fixedly arranged between the cylinder 41 and the push plate 43 and the baffle 11 is arranged as a telescopic structure. When the push plate 43 pushes out the bentonite above the push plate, the baffle 11 is pulled up to prevent the bentonite from entering under the push plate 43 and hindering the push plate 43 from resetting.

[0041] Embodiment 2

[0042] like Figure 2 As shown, the components that are the same or corresponding to those in the first embodiment are marked with the corresponding figure marks in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The difference between the second embodiment and the first embodiment is that the opening 44 is set as a fan-shaped structure.

[0043] Here, in this embodiment, the opening 44 is configured as a fan-shaped structure, so that the bentonite can be pushed out better.

[0044] Working process:

[0045] After the operator conveys the bentonite to the fixed cylinder 2 and the cylinder body 41 through the conveying pipe and fills them, the first motor 31 drives the boss 33 to rotate. During the rotation of the boss 33, the push rod 42 lifts the push plate 43 when passing the protrusion, and the baffle 21 slides into the fixed cylinder 2. The push plate 43 drives the bentonite above the push plate 43 to move toward the opening 44. At the same time, the rotating cylinder 5 drives the scraper 61 to pass through the opening 44, driving the bentonite to move to the upper surface of the fixed cylinder 2 and the bentonite is scraped flat on its surface. The gear 74 rotates under the action of the rack 72 while revolving, and the gear 74 drives the auger 73 to rotate. The auger 73 can stir the bentonite when passing through the bentonite. While stirring, the discharge port 92 corresponds to the leakage hole 91, and the sodium salt falls out of the salt storage box 93, is evenly sprinkled on the bentonite, and is stirred by the auger 73. Then it is fully and evenly mixed with bentonite. During this process, when the bentonite on the push plate 43 is taken away, the push plate 43 is reset, and the baffle 21 slides out to the opening 44 to close the opening 44. Subsequently, the conveying pipe conveys the bentonite to between the fixed cylinder 2 and the cylinder body 41 until it is filled. Then the push plate 43 pushes the bentonite to the opening 44 again, and the latter group of scrapers 61 and auger 73 perform the same work, and the scraper 61 drives the unmixed bentonite to move and can push the mixed bentonite to the bottom of the rotating cylinder 5, and is stirred by other augers 73 to ensure its mixing effect. When the bentonite in the rotating cylinder 5 is fully mixed and reaches a certain amount, the rotating cylinder 5 rotates to the corresponding position of the discharge port 101 and the opening and closing plate 102, and then the switch controls the opening and closing plate 102 to open, and the bentonite in the rotating cylinder 5 is discharged.
