High-purity isopropyl alcohol has the characteristics of being colorless, transparent, volatile, low in toxicity, having a high flash point, and being non-flammable. High-purity isopropyl alcohol can be used to manufacture a variety of chemical products such as surfactants, plastics, coatings, bactericides, and pharmaceutical raw materials. It is also widely used in the cleaning and maintenance of semiconductor and electronics industries, precision instruments, and optical instruments.

[0003] At present, ultra-clean high-purity isopropyl alcohol is usually purified and refined from industrial-grade isopropyl alcohol as raw material. In the preparation process of high-purity isopropyl alcohol, it is necessary to treat the metal impurities and anions therein to meet industrial requirements. Specifically, a complexing agent is added to the industrial-grade isopropyl alcohol raw material, the mixture is allowed to stand to form a sedimentation, and the upper liquid is taken out; the upper liquid can be taken out by suction, and the upper liquid close to the lower liquid will cause disturbance to the sediment in the lower liquid during the suction process, thereby causing the sediment to remix with the remaining upper liquid, resulting in the discharged upper liquid containing a large amount of sediment, which affects the purity of the prepared isopropyl alcohol.

[0004] In view of this, in order to overcome the above technical problems, the present invention proposes a device for preparing high-purity isopropanol, which solves the above technical problems. Summary of the invention

[0013] Preferably, the clamping member is a plate-shaped object; the surfaces of the two clamping members close to each other are corrugated surfaces; and the crests and troughs of the corrugated surfaces on the two clamping members correspond one to one.

[0014] Preferably, surfaces of the two clamping members that are close to each other are provided with rotation grooves; a No. 1 rotating rod is rotationally connected between the two groove walls of the rotation groove on one of the clamping members, and a No. 2 rotating rod is rotationally connected between the two groove walls of the rotation groove on the other clamping member; the No. 1 rotating rod and the No. 2 rotating rod are staggered with each other.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] like Figures 1 to 8 As shown, a high-purity isopropanol preparation device according to the present invention comprises:

[0035] Shell 1; the shell 1 comprises a top plate 11, a side plate 12 and a bottom plate 13 connected in sequence from top to bottom; the lower end of the bottom plate 13 is connected to a bracket 14; the center of the top plate 11 is fixedly connected to an upper tube 15; the center of the bottom plate 13 is fixedly connected to a lower tube 16; valves are provided in the upper tube 15 and the lower tube 16;

[0036] Reaction capsule 2; the reaction capsule 2 is located inside the housing 1; the reaction capsule 2 is made of a flexible transparent material; the upper port of the reaction capsule 2 is connected to the upper tube 15, and the lower port of the reaction capsule 2 is connected to the lower tube 16;

[0037] Frame 3; the frame 3 is located inside the shell 1 and surrounds the reaction capsule 2; two opposite inner walls of the frame 3 are provided with a slide groove 31; both ends of the slide groove 31 are slidably connected to the slider 32; a No. 1 screw 33 is rotatably connected between the two groove walls of one of the slide grooves 31; the threads of the two ends of the No. 1 screw 33 are arranged oppositely; the two ends of the No. 1 screw 33 are threadedly connected with the corresponding slider 32; the outer side of the frame 3 is fixedly connected to a No. 1 motor 34; the No. 1 motor 34 is fixedly connected to one end of the No. 1 screw 33;

[0038] Clamping member 4; there are two clamping members 4; the clamping member 4 is connected between the two slide grooves 31 and the end portion is connected to the corresponding slider 32;

[0039] Controller; the controller is used to control the automatic operation of the preparation device;

[0040] At work, currently ultra-clean high-purity isopropyl alcohol is usually purified and refined from industrial-grade isopropyl alcohol as a raw material. In the preparation process of high-purity isopropyl alcohol, it is necessary to treat the metal impurities and anions therein to meet industrial requirements. Specifically, a complexing agent is added to the industrial-grade isopropyl alcohol raw material, the mixture is allowed to stand to form a sedimentation, and the upper liquid is taken out; the upper liquid can be taken out by suction, and the upper liquid close to the lower liquid will cause disturbance to the sediment in the lower liquid during the process of being drawn away, thereby causing the sediment to remix with the remaining upper liquid, resulting in the discharged upper liquid containing a large amount of sediment, which affects the purity of the prepared isopropyl alcohol;

[0041] Therefore, the staff of the present invention closes the valve of the lower tube 16 and opens the valve inside the upper tube 15 through the controller, and adds the industrial-grade isopropyl alcohol raw material into the upper tube 15. After the isopropyl alcohol raw material enters the reaction capsule 2 along the upper tube 15, the reaction capsule 2 changes from the original deflated state to the bulging state. Then the staff controls the No. 1 motor 34 to rotate back and forth in the forward and reverse directions through the controller. The rotating No. 1 motor 34 drives the No. 1 screw 33 to rotate back and forth synchronously. During the back and forth rotation of the No. 1 screw 33, the two sliders 32 in the same slide trough 31 will be driven to approach and move back and forth. The two clamping members 4 move away from each other, so that the two clamping members 4 move back and forth towards and away from each other under the drive of the corresponding sliders 32, so that the two clamping members 4 hit the outer wall of the reaction capsule 2 back and forth, and the reaction capsule 2 shakes under the action of the clamping members 4. During the shaking process of the reaction capsule 2, the complexing agent is added to the inner side of the reaction capsule 2 along the upper tube 15, and the upper tube 15 is closed. The shaking reaction capsule 2 will drive the isopropyl alcohol raw material and the complexing agent inside to shake, thereby achieving mixing. After the isopropyl alcohol raw material and the complexing agent are mixed for a period of time and left to stand for a period of time, the upper tube 15 is opened, and the pump is removed. One end of the liquid pump's liquid extraction tube passes through the upper tube 15 and extends to the inside of the reaction capsule 2. Then the controller controls the No. 1 motor 34 to rotate only in the forward direction. The No. 1 motor 34 drives the two clamping members 4 to approach each other through the No. 1 screw 33. The two clamping members 4 squeeze the reaction capsule 2 during the movement of approaching each other until the two clamping members 4 clamp the reaction capsule 2, that is, the inner walls of the reaction capsule 2 overlap. The position where the inner walls of the reaction capsule 2 overlap is the position where the upper liquid layer is separated from the lower liquid layer. In this way, by clamping the reaction capsule 2, the upper liquid layer and the lower liquid layer are disconnected. In this way, the liquid extraction pump is in the upper While the layer liquid is being sucked, the staff controls the lower tube 16 to open, so as to collect the lower layer liquid coming out of the lower tube 16. After the upper and lower layer liquids are discharged, the staff controls the No. 1 motor 34 to rotate in the opposite direction. The rotating No. 1 motor 34 drives the two clamping parts 4 to move away from each other, so as to loosen the reaction capsule 2. Then the staff closes the lower tube 16, opens the upper tube 15, and adds the industrial-grade isopropyl alcohol raw material again. The upper layer liquid originally extracted from the upper tube 15 will be dehydrated and filtered, and then distilled to obtain high-purity isopropyl alcohol.

[0042] The present invention uses two clamping members 4 to separate the inner upper layer liquid from the lower layer liquid from the outside of the reaction capsule 2, so that the upper layer liquid and the lower layer liquid will not cause mutual disturbance during the process of being taken out, thereby reducing the difficulty of subsequent processes and improving the purity of isopropyl alcohol.

[0043] As an embodiment of the present invention, the square frame 3 is slidably connected to the inner side of the side plate 12; a No. 2 screw 17 is rotatably connected between the top plate 11 and the bottom plate 13; a No. 2 motor 18 is fixedly connected to the upper end of the top plate 11; an output shaft of the No. 2 motor 18 is fixedly connected to one end of the No. 2 screw 17; the No. 2 screw 17 passes through the square frame 3 and is threadedly connected to the frame 3;

[0044] During operation, before the staff adds industrial-grade isopropyl alcohol into the reaction capsule 2, the controller will first control the No. 2 motor 18 to rotate, and the rotating No. 2 motor 18 will drive the No. 2 screw 17 to rotate. The No. 2 screw 17 is threadedly connected to the frame 3, so the rotation of the No. 2 screw 17 will drive the frame 3 to move up until the frame 3 moves up to the limit position. Then, when the upper tube 15 is closed and the lower tube 16 is opened, the controller controls the two clamping members 4 to approach each other, so that the part of the reaction capsule 2 close to the top plate 11 is clamped by the two clamping members 4, so that the inner walls of the reaction capsule 2 overlap and fit tightly. Then, the controller drives the frame 3 to move down through the No. 2 motor 18, and the frame 3 drives the two clamping members 4 to clamp the outer wall of the reaction capsule 2 at the same time. The two clamping members 4 are moved downward step by step, so that the gas inside the reaction capsule 2 is discharged along the lower tube 16 through the two clamping members 4, and the impurities on the inner wall of the reaction capsule 2 are scraped away under the squeezing of the two clamping members 4. At the same time, the impurities are discharged from the lower tube 16 under the action of the gas being discharged from the lower tube 16, thereby ensuring the cleanliness of the inner wall of the reaction capsule 2. Then the staff closes the lower tube 16 and controls the two clamping members 4 to move away from each other. Then the staff opens the upper tube 15 and adds industrial-grade isopropyl alcohol from the upper tube 15 to the inner side of the reaction capsule 2. The industrial-grade isopropyl alcohol contained in the reaction capsule 2 is not in a full state. Then the staff drives the frame 3 to move upward and close to the top plate 11 through the No. 2 motor 18. Then the controller controls the No. 1 motor 34 to drive the two clamping members 4 to move closer to each other and The reaction capsule 2 is clamped. In the present invention, "clamping" means that the inner walls of the reaction capsule 2 are overlapped to separate the upper and lower spaces, while "pinching flat" in the present invention means that the clamped part of the reaction capsule 2 is flat, but the upper and lower spaces are ventilated by a gap. In the present invention, the upper and lower spaces formed after the reaction capsule 2 is clamped by two clamping members 4 are an upper chamber and a lower chamber, respectively. In this way, when the upper part of the reaction capsule 2 is clamped, the complexing agent can only fall into the upper chamber after being added from the upper tube 15. Then the upper tube 15 is closed. After the complexing agent contacts the metal impurities and anions in the isopropanol in the upper chamber to form a precipitate, the staff controls the box 3 to move downward, and controls the two clamping members 4 to change from the clamped state to the pinning state. During the downward movement of the two clamping members 4, The liquid in the lower chamber enters the upper chamber, making the space of the upper chamber larger. After the square frame 3 stops moving, the two clamping members 4 change from the clamping state to the clamping state, so that the square frame 3 is controlled to move downward in sequence until it moves downward to the limit position, so that the metal impurities and anions in the reaction capsule 2 are processed in sequence, thereby avoiding the problem of incomplete treatment of metal impurities and anions in the isopropanol caused by the complexing agent in the prior art directly settling to the lower part without completely contacting with the upper liquid; the sedimentation state of the sediment inside the reaction capsule 2 is observed by observing the transparent side plate 12 and the transparent reaction capsule 2, and the reaction capsule 2 is given a pressure in the process of squeezing the reaction capsule 2 by the two clamping members 4, thereby accelerating the sedimentation speed of the sediment in the reaction capsule 2;While waiting for the sediment inside the reaction capsule 2 to stand still, the two clamping pieces 4 are away from each other and do not contact the reaction capsule 2. After standing still for a period of time, the sediment inside the reaction capsule 2 settles to form an upper layer of liquid and a lower layer of liquid. Then the staff will control the box 3 to move up or down, and cooperate with the two clamping pieces 4 to approach each other. At the same time, through observation or other methods, the two clamping pieces 4 are controlled to clamp at the boundary between the upper layer of liquid and the lower layer of liquid. Then, there is no need to use a liquid pump, but directly open the upper tube 15, and connect the upper tube 15 to the collection bucket. The box 3 is controlled to move down to drive the two clamping pieces 4 to move up in a clamped state, so as to pull out the upper layer of liquid. After the upper layer of liquid is pulled out, the lower tube 16 is opened and the box 3 is controlled to move down. The box 3 will drive the two clamping pieces 4 to move down in a clamped state, so as to pull out the lower layer of liquid from the lower tube 16, and at the same time, the impurities attached to the inner wall of the reaction capsule 2 will be pulled out together to avoid affecting the next reaction. ;

[0045] As an embodiment of the present invention, the clamping member 4 is a plate-shaped object; the surfaces of the two clamping members 4 close to each other are corrugated surfaces; the crests and troughs of the corrugated surfaces on the two clamping members 4 correspond to each other one by one;

[0046] During operation, when the two clamping members 4 approach each other to achieve a clamping state for the reaction capsule 2, since the surfaces of the two clamping members 4 that are close to each other are corrugated surfaces, and the crests of the corrugated surface on one of the clamping members 4 are aligned with the troughs of the corrugated surface on the other clamping member 4, after the reaction capsule 2 is clamped by the two clamping members 4, the clamped portion of the reaction capsule 2 is in a corrugated clamping state when viewed from the side. Therefore, compared with the original straight and flat clamping state, the corrugated clamping state has a better isolation effect on the upper chamber and the lower chamber, thereby preventing the liquid inside the upper chamber and the lower chamber from flowing through, and also preventing the upper layer of liquid from passing through the two clamping members 4 to flow to the lower layer of liquid.

[0047] As an embodiment of the present invention, the surfaces of the two clamping members 4 close to each other are both provided with a rotation groove 41; a first rotating stick 5 is rotationally connected between the two groove walls of the rotation groove 41 on one of the clamping members 4, and a second rotating stick 6 is rotationally connected between the two groove walls of the rotation groove 41 on the other clamping member 4; the first rotating stick 5 and the second rotating stick 6 are staggered with each other;

[0048] During operation, the two clamping members 4 approach each other under the action of the controller, one of the clamping members 4 drives the No. 1 rotating stick 5 to move synchronously during the movement, and the other clamping member 4 drives the No. 2 rotating stick 6 to move synchronously during the movement, and the No. 1 rotating stick 5 and the No. 2 rotating stick 6 will squeeze the reaction capsule 2 during the movement of approaching each other, so that the reaction capsule 2 is deformed after being squeezed, and since the No. 1 rotating stick 5 and the No. 2 rotating stick 6 are staggered with each other, after the No. 1 rotating stick 5 and the No. 2 rotating stick 6 clamp the reaction capsule 2, the No. 1 rotating stick 5 is located between the two adjacent No. 2 rotating sticks 6, and the No. 2 rotating stick 6 is located between the adjacent No. 2 rotating sticks 6. The rod 6 is located between two adjacent No. 1 rotating rods 5, so that the reaction capsule 2 is in a corrugated clamping state from the side after being clamped. The No. 1 rotating rod 5 and the No. 2 rotating rod 6 realize that the surfaces of the two clamping members 4 that are close to each other are corrugated surfaces. More importantly, during the up and down movement of the two clamping members 4 after the box 3 controls the two clamping members 4 to clamp the reaction capsule 2, the No. 1 rotating rod 5 and the No. 2 rotating rod 6 will both rotate in the corresponding rotating groove 41, so that the sliding friction between the clamping member 4 and the reaction capsule 2 is converted into rolling friction, thereby reducing the degree of wear of the outer wall of the reaction capsule 2 by the clamping member 4 and the movement resistance.

[0049] As an embodiment of the present invention, the outer walls of the No. 1 rotating stick 5 and the No. 2 rotating stick 6 are both provided with a strip groove 61; the strip groove 61 is provided along the length direction of the No. 1 rotating stick 5; the inner ends of the strip groove 61 are both slidably connected with two push blocks 62; the two push blocks 62 are connected by an outwardly arched spring piece 63; the push blocks 62 protrude from the strip groove 61;

[0050] During operation, when the two clamping members 4 are clamped on the reaction capsule 2, the frame 3 drives the two clamping members 4 to move up and down. Since the outer walls of the No. 1 rotating stick 5 and the No. 2 rotating stick 6 are both provided with strip grooves 61, and the strip grooves 61 have spring pieces 63 arched outward, the friction between the No. 1 rotating stick 5 and the outer wall of the reaction capsule 2 is increased, and the friction between the No. 2 rotating stick 6 and the outer wall of the reaction capsule 2 is also increased. In this way, the No. 1 rotating stick 5 and the No. 2 rotating stick 6 rotate in the corresponding rotating grooves 41 under the friction of the outer wall of the reaction capsule 2. The No. 1 rotating stick 5 and the No. 2 rotating stick 6 will drive the corresponding spring pieces 63 to rotate during the rotation process, and the middle part of the spring pieces 63 will be close to the strip grooves 61 under the extrusion of the reaction capsule 2. As the bottom of the strip groove 61 moves, the arched shape of the spring piece 63 will become slower, and the push block 62 protrudes from the strip groove 61. Therefore, when the arched part in the middle of the spring piece 63 is squeezed by the reaction capsule 2, the two push blocks 62 are in contact with the surface of the reaction capsule 2 and move away from each other. Therefore, under the action of the two push blocks 62 pushing outward from the middle, the edge part of the reaction capsule 2 to be clamped by the clamping member 4 is spread out, avoiding the wrinkles and flanging of the edge of the reaction capsule 2 affecting the clamping effect of the two clamping members 4. At the same time, the spring piece 63 is pressed and driven by the rotating rod to move into the corresponding rotating groove 41, and the spring piece 63 in the rotating groove 41 is cyclically exposed to achieve continuous smoothing of the edge of the reaction capsule 2.

[0051] As an embodiment of the present invention, a first spring 64 is provided on the side away from each other of the two push blocks 62 in the same strip groove 61; the other end of the first spring 64 is connected to the groove wall of the strip groove 61;

[0052] During operation, the central axis of the reaction capsule 2 is located in the middle of the strip groove 61. In order to prevent the spring sheet 63 from being compressed and driving the two push blocks 62 to smooth the edge of the reaction capsule 2 beyond the range of the reaction capsule 2, a No. 1 spring 64 is arranged between the push block 62 and the groove wall of the strip groove 61. The two No. 1 springs 64 in the strip groove 61 will give the two push blocks 62 a force to approach each other, and the two No. 1 springs 64 will transfer the force to the spring sheet 63, thereby pushing the spring sheet 63 to the middle of the strip groove 61, so that the outer wall position of the middle part of the spring sheet 63 squeezed by the reaction capsule 2 is consistent with the middle position of the reaction capsule 2 after being compressed, so that the two push blocks 62 can smooth the edge of the flat reaction capsule 2 without exceeding the range of the edge of the reaction capsule 2.

[0053] As an embodiment of the present invention, a guide belt 65 is sleeved on the outer side of the rotating roller; the inner side of the guide belt 65 is connected to the middle part of the spring piece 63;

[0054] During operation, the rotating stick rotates under the friction of the reaction capsule 2, and the rotation of the rotating stick will drive the guide belt 65 to rotate. The guide belt 65 serves to limit the middle part of the spring piece 63 to prevent the spring piece 63 from arching and bending. More importantly, when the rotating stick rotates to move into the inner side of the rotating groove 41, the middle part of the spring piece 63 is squeezed by the guide belt 65, so that the spring piece 63 is in a gentle state and moves into the rotating groove 41, while the other spring pieces 63 will bounce toward the reaction capsule 2 to vibrate after moving out of the rotating groove 41 as the rotating stick rotates. The spring pieces 63 will pull the guide belt 65 in the process of popping out to the outside, so that the middle parts of the other spring pieces 63 are further retracted to the corresponding strip groove 61 under the pulling of the guide belt 65, thereby reducing the movement resistance in the rotating groove 41 caused by the arching of the spring piece 63 and improving the smoothness of the rotation of the rotating stick.

[0055] As an embodiment of the present invention, a groove 66 is provided on a side of the push block 62 close to the reaction capsule 2; an extension block 67 is slidably connected in the groove 66; the extension block 67 is connected to the bottom of the groove 66 via a second spring 68;

[0056] During operation, when the rotating rod rotates under the friction of the outer wall of the reaction capsule 2, the rotating rod will drive the strip groove 61 to move out of the rotating groove 41, and the strip groove 61 will drive the middle part of the spring 63 to contact the reaction capsule 2. At the same time, the extension block 67 also contacts the outer wall of the reaction capsule 2 under the action of the No. 2 spring 68, so that the reaction capsule 2 is supported. As the middle part of the spring is deformed, the two extension blocks 67 will be driven away from each other. During the process of the extension blocks 67 moving away from each other, the edges of the reaction capsule 2 will be smoothed. In this embodiment, through the action of the No. 2 spring 68, the rigid smoothing of the reaction capsule 2 by the push block 62 is changed into flexible smoothing, thereby avoiding the wear of the reaction capsule 2 caused by the rigid smoothing. At the same time, the flexible smoothing can also be used to smooth the surface of the reaction capsule 2 when the surface is uneven due to impurities mixed inside.
