Description

Technical Field

[0001] This invention relates to the field of washing equipment technology, and specifically to a washing equipment for crude adipic acid slurry. Background Technology

[0002] In the chemical industry, adipic acid, as an important organic chemical raw material, is widely used in the production of products such as nylon and polyurethane. However, due to technological limitations, traditional adipic acid production processes often result in high levels of nitrates and pseudonitric acid. The presence of these impurities not only affects product purity but can also lead to increased breakage rates during nylon salt polymer spinning and decreased viscosity and yellowing during thermoplastic polyurethane rubber production. These problems limit the application of adipic acid in high-end markets and increase production costs for companies.

[0003] Therefore, adipic acid needs to be washed. In the existing technology, adipic acid and washing water are mixed and stirred in a stirrer to wash adipic acid. However, conventional stirring and washing devices, such as the lithium carbonate crude product washing device disclosed in CN210411763U, have problems such as insufficient stirring and mixing, incomplete washing, and low washing efficiency when stirring and washing raw materials.

[0022] Furthermore, multiple stirring units are arranged vertically at intervals, and the distance between the lowest stirring unit and the bottom of the washing tank is equal to the length of the stirring blade in the radial direction of the support rod. When the stirring frame moves to the lowest position, during the process of the stirring blade switching from the second state to the first state, the stirring blade has a moment of contact with the bottom of the washing tank, thereby stirring up the adipic acid that has settled at the bottom of the washing tank. This solves the problem of incomplete washing caused by adipic acid settling at the bottom of the washing tank, further optimizing the washing effect. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] like Figures 1 to 10 As shown, the washing device for crude adipic acid slurry provided in this embodiment of the invention includes a washing tank 100, a stirring mechanism 200, a driving component 400, a guiding component 500, and an adjusting component.

[0037] The washing tub 100 is installed vertically; a top cover 110 is provided on top of the washing tub 100;

[0038] The stirring mechanism 200 includes a stirring frame 210 and at least two stirring units 220. The stirring frame 210 is coaxially disposed within the washing tub 100 via a support assembly 300, and can rotate relative to the washing tub 100 and move vertically relative to the washing tub 100. Multiple stirring units 220 are spaced apart along the vertical direction. Each stirring unit 220 includes at least three support rods 224 and at least three stirring blades 221. The multiple support rods 224 are evenly distributed circumferentially around the stirring frame 210, fixedly connected to the stirring frame 210, and connected end-to-end. Multiple stirring blades 221 are rotatably mounted on the multiple support rods 224. The stirring blades 221 have a first state and a second state. The stirring blades 221 are divided into two parts along their length by the support rods 224, with one part being longer than the other. When the stirring blades 221 are in the first state, the longer part is located outside the stirring frame 210. Figure 5 When the stirring blade 221 is in the second state, the longer part is located inside the stirring frame 210, as shown in the reference. Figure 10 ;

[0039] The drive assembly 400 is used to drive the stirring rack 210 to rotate around its own axis;

[0040] The guide assembly 500 is used to drive the stirring frame 210 to move back and forth up and down relative to the washing tub 100 when the stirring frame 210 rotates around its own axis, and after changing the direction of movement, it accelerates to move a preset distance and then moves at a constant speed, so that the stirring blade 221 rotates around the support rod 224 during the accelerated movement.

[0041] The adjustment component is used to rotate the stirring blade 221 by 180° during each acceleration movement of the stirring frame 210, thereby switching the state of the stirring blade 221.

[0042] In use, adipic acid and washing water are fed into the washing tub 100. The drive assembly 400 is activated, causing the stirring frame 210 to rotate around its own axis. Initially, the stirring frame 210 is located in the middle of the washing tub 100, and the stirring blades 221 are in the first state. As the stirring frame 210 rotates around its own axis, the stirring blades 221 rotate synchronously around the axis of the stirring frame 210, mixing the adipic acid and washing water to complete the washing of the adipic acid. Simultaneously, the guide assembly 500 moves the stirring frame 210 upwards relative to the washing tub 100. After reaching the highest position, under the action of the guide assembly 500, the stirring frame 210 changes its direction of movement to accelerate downward movement a preset distance. During this accelerated movement, the stirring blades 221 experience increased thrust from the water, causing them to rotate around the axis of the connected support rod 224. Simultaneously, under the action of the adjustment assembly, the stirring blades 221 rotate 180°, moving from the initial position... Figure 4The first state shown switches to as follows Figure 5 The second state shown;

[0043] Afterwards, the stirring rack 210 begins to move downwards at a constant speed; when the stirring rack 210 reaches its lowest position, under the action of the guide component 500, the stirring rack 210 changes its direction of movement and begins to move upwards, accelerating the movement of a preset distance. During the acceleration of the stirring rack 210, the stirring blade 221 is subjected to increased thrust from the water, and the stirring blade 221 rotates around the axis of the connected support rod 224, causing it to flip. At the same time, under the action of the adjustment component, the stirring blade 221 switches from the second state to the first state; subsequently, the stirring blade 221 moves upwards at a constant speed.

[0044] The above process is then repeated, with the stirring rack 210 moving up and down repeatedly inside the washing tank 100. This causes the solution inside the washing tank 100 to flow from top to bottom inside the stirring rack 210, and the solution outside the stirring rack 210 to flow from bottom to top, thus creating a circulation of the solution inside the washing tank 100. This ensures that adipic acid continues to come into contact with the washing water, effectively washing the adipic acid and solving the problem of incomplete washing.

[0045] In a further embodiment, such as Figure 1 , Figure 2 , Figure 3 and Figure 6 , Figure 7 As shown; multiple support legs 103 are evenly distributed around the lower end of the washing tub 100, and a top cover 110 is provided on the top of the washing tub 100. By providing the top cover 110, adipic acid and washing water are prevented from splashing out of the washing tub 100 during the washing process.

[0046] In a further embodiment, such as Figure 3 , Figure 5 , Figure 6 , Figure 8 , Figure 10As shown, the top cover 110 and the washing tub 100 define a washing chamber; the guide assembly 500 includes a guide sleeve 510, which is fixedly connected to the top cover 110 and located inside the washing chamber. A guide groove 520 is formed on the inner wall of the guide sleeve 510. The guide groove 520 includes a first spiral groove 521, a second spiral groove 522, a third spiral groove 523, and a fourth spiral groove 524. The second spiral groove 522 and the fourth spiral groove 524 have the same length and pitch, but opposite directions of rotation. Both extend vertically. The upper part of the fourth spiral groove 524... The first spiral groove 521 is lower than the upper end of the second spiral groove 522; the two ends of the first spiral groove 521 are connected to the upper ends of the second spiral groove 522 and the fourth spiral groove 524 respectively, and the spiral direction of the first spiral groove 521 is the same as that of the second spiral groove 522, and the pitch of the first spiral groove 521 is greater than that of the second spiral groove 522; the two ends of the third spiral groove 523 are connected to the lower ends of the second spiral groove 522 and the fourth spiral groove 524 respectively, and the spiral direction of the third spiral groove 523 is the same as that of the fourth spiral groove 524, and the pitch of the third spiral groove 523 is greater than that of the fourth spiral groove 524.

[0047] The stirring rack 210 includes a main rod 211 and multiple auxiliary rods 213 evenly distributed around the main rod 211. Both the main rod 211 and the auxiliary rods 213 are vertically arranged. The auxiliary rods 213 are fixedly connected to the main rod 211 by horizontally arranged connecting rods 212. A slider 530 is rotatably connected to the main rod 211. The axis of rotation of the slider 530 extends radially along the main rod 211. The slider 530 is slidably installed in the guide groove 520. During the rotation of the stirring rack 210, when the slider 530 is located in the first spiral groove 521 and the second spiral groove 522, the stirring rack 210 moves upward. When the slider 530 is located in the third spiral groove 523 and the fourth spiral groove 524, the stirring rack 210 moves downward. Multiple support rods 224 are respectively arranged between two adjacent auxiliary rods 213. The support rods 224 are horizontally arranged and their two ends are fixedly connected to the two auxiliary rods 213 respectively.

[0048] In the initial state, the stirring rack 210 is located in the middle of the washing tank 100. At this time, the slider 530 is located in the second spiral groove 522, and the stirring blade 221 is in the first state, with the longer part of the stirring blade 221 located on the outside of the stirring rack 210. After the drive mechanism is started, the drive mechanism drives the stirring rack 210 to rotate, and the slider 530 rotates in the second spiral groove 522 and moves upward at a constant speed in the vertical direction. The stirring rack 210 drives the stirring blade 221 to rotate around the axis of the stirring rack 210 and move upward at the same time, so that the solution between the stirring rack 210 and the washing tank 100 flows upward.

[0049] After the stirring frame 210 moves upward a preset distance, it reaches its highest position. Then, the slider 530 disengages from the second spiral groove 522 and enters the third spiral groove 523. Subsequently, as the stirring frame 210 rotates, the slider 530 rotates within the third spiral groove 523. The stirring frame 210 changes its direction of movement. Because the pitch of the third spiral groove 523 is greater than that of the second spiral groove 522, when the slider 530 slides within the third spiral groove 523, the stirring frame 210 begins to accelerate downward. The stirring blades 221 rotate around the support rod 224 under the influence of inertia and the thrust of the water. The stirring blades 221 move from... Figure 4 The first state shown is switched to Figure 5 In the second state shown, the longer portion rotates to the inside of the stirring rack 210.

[0050] After the stirring rack 210 moves downward a preset distance, the slider 530 disengages from the third spiral groove 523 and enters the fourth spiral groove 524. The stirring rack 210 moves downward at a constant speed. The stirring rack 210 drives the stirring blade 221 to rotate around the axis of the stirring rack 210 while moving downward, so that the solution inside the stirring rack 210 flows downward.

[0051] The stirring frame 210 continues to move downwards. After reaching the lowest position, the slider 530 disengages from the fourth spiral groove 524 and enters the first spiral groove 521. Subsequently, as the stirring frame 210 rotates, the slider 530 rotates within the first spiral groove 521. The stirring frame 210 changes its direction of movement and begins to accelerate upwards. Under the influence of inertia and the thrust of the water, the stirring blades 221 rotate around the support rod 224. The position of the stirring blades 221 returns to its initial state. Figure 5 The second state shown is switched to Figure 4 The first state is shown.

[0052] The above process is repeated. When the stirring blade 221 is in the first state, the solution between the stirring rack 210 and the washing tank 100 flows upward. When the stirring blade 221 is in the second state, the solution in the stirring rack 210 flows downward, so that the solution in the washing tank 100 is in a continuous circulation state, so that the adipic acid and the washing water are fully in contact, and the adipic acid is washed, thus solving the problem of incomplete washing.

[0053] In a further embodiment, such as Figure 3 , Figure 4 , Figure 9As shown; the stirring blade 221 includes a sleeve body 222 and a blade body 223; the sleeve body 222 is axially movable and rotatably sleeved on the support rod 224; the adjustment assembly includes multiple adjustment blocks 610 and multiple adjustment springs 620, the number of which is the same as the number of stirring blades 221; the adjustment blocks 610 and adjustment springs 620 are coaxially mounted on the support rod 224 and are located on both sides of the axial direction of the sleeve body 222, respectively; the adjustment blocks 610 are fixedly mounted on the support rod 224; the adjustment springs 620 have a tendency to move the sleeve body 222 toward the adjustment blocks 610; the end face of the adjustment block 610 facing the stirring blade 221 is provided with a wave-shaped annular track 611, the wave... The wavy annular track 611 includes two alternating peaks 612 and two troughs 613. The two peaks 612 are located on the upper and lower sides of the adjusting block 610, respectively. The distance between the peaks 612 and the sleeve body 222 is less than the distance between the troughs 613 and the sleeve body 222. The two troughs 613 are located on the inner and outer sides of the adjusting block 610, respectively. A protruding rod 630 is fixedly connected to one end of the sleeve body 222 facing the adjusting block 610. The axis of the protruding rod 630 is parallel to the axis of the support rod 224. The protruding rod 630 is slidably installed in the wavy annular track 611. The lengths of the first spiral groove 521 and the second spiral groove 522 allow the stirring blade 221 to rotate 90° around the axis of the support rod 224.

[0054] Initially, the stirring blade 221 is in the first state, and the protruding rod 630 is at the trough 613. When the stirring frame 210 moves to its highest position, as the stirring frame 210 rotates, the slider 530 enters the third spiral groove 523. While the stirring frame 210 rotates, it accelerates downwards. Under the influence of inertia and the thrust of the water, the stirring blade 221 rotates 90° around the axis of the support rod 224. During this rotation, the protruding rod 630 moves from the trough 613 to the crest 613. 12 moves, causing the sleeve body 222 to compress the adjusting spring 620. When the convex rod 630 passes the crest 612, the sleeve body 222 no longer compresses the adjusting spring 620, and the adjusting spring 620 returns to its initial state. The adjusting spring 620 pushes the sleeve body 222 to move towards the adjusting block 610, and the convex rod 630 moves from the crest 612 to the trough 613. The stirring blade 221 switches from the first state to the second state. After that, the slider 530 slides in the fourth spiral groove 524.

[0055] When the stirring rack 210 moves to its lowest position, as the stirring rack 210 rotates, the slider 530 enters the first spiral groove 521. The stirring rack 210 accelerates upward, and the stirring blade 221 rotates around the axis of the support rod 224 under the action of inertia and the thrust of the water. During the rotation of the stirring blade 221, the protruding rod 630 moves from the trough 613 to the crest 612, thereby causing the sleeve body 222 to compress the adjusting spring 620. When the protruding rod 630 passes the crest 612, the sleeve body 222 no longer compresses the adjusting spring 620, and the adjusting spring 620 returns to its initial state. The adjusting spring 620 pushes the sleeve body 222 to move towards the adjusting block 610, and the protruding rod 630 moves from the crest 612 to the trough 613. The stirring blade 221 switches from the second state to the first state and returns to its initial state. After that, the slider 530 slides in the second spiral groove 522.

[0056] In a further embodiment, such as Figure 2 , Figure 7 , Figure 8 As shown, the drive assembly 400 includes a motor 410 and a drive gear 420, with the drive gear 420 mounted on the output end of the motor 410. A transmission gear rod 430 is fixedly connected to the upper end of the main rod 211, and the transmission gear rod 430 meshes with the drive gear 420 for transmission. After the motor 410 is started, it drives the drive gear 420 to rotate synchronously. The drive gear 420, through the transmission gear rod 430, drives the main rod 211 to rotate around its own axis, thereby driving the stirring mechanism 200 to rotate around the axis of the washing tub 100.

[0057] In a further embodiment, such as Figure 3 , Figure 4 As shown, multiple stirring units 220 are arranged at intervals along the vertical direction, and the distance between the lowest stirring unit 220 and the bottom of the washing tank 100 is equal to the length of the longer part of the stirring blade 221 in the radial direction of the support rod 224. When the stirring frame 210 moves to the lowest position, during the process of switching from the second state to the first state, the stirring blade 221 has a moment of contact with the bottom of the washing tank 100, thereby stirring up the adipic acid that has settled at the bottom of the washing tank 100, thus solving the problem of incomplete washing caused by the adipic acid settling at the bottom of the washing tank 100, and optimizing the washing effect of adipic acid.

[0058] In a further embodiment, such as Figure 2 , Figure 7As shown, the support assembly 300 includes a fixed base 340, a fixed plate 310, multiple telescopic rods 320, and multiple support springs 330; the fixed base 340 is located on the top cover 110 and is fixedly installed on the top cover 110; the fixed plate 310 is movably disposed above the top cover 110, and the main rod 211 is rotatably connected to the fixed plate 310; the telescopic rods 320 extend vertically, and the upper and lower ends of the telescopic rods 320 are fixedly connected to the fixed plate 310 and the fixed base 340, respectively; the multiple support springs 330 are respectively fitted onto the multiple telescopic rods 320.

[0059] In the initial state, the support spring 330 is in its natural state. When the stirring rack 210 moves upward relative to the initial state, the telescopic rod 320 extends and the support spring 330 is stretched. When the stirring rack 210 moves downward relative to the initial state, the telescopic rod 320 shortens and the support spring 330 is compressed.

[0060] In a further embodiment, such as Figure 1 , Figure 2 , Figure 6 As shown, the top cover 110 has a feed inlet 111, and the washing tub 100 has a discharge outlet 101 at the bottom, with the discharge outlet 101 connected to a discharge pipe 102. When washing begins, adipic acid and washing water are injected into the washing tub 100 through the feed inlet 111; after washing is completed, the adipic acid is discharged through the discharge pipe 102.

[0061] In a further embodiment, such as Figure 8 As shown, a telescopic column 531 is fixedly installed on the main rod 211 in the radial direction.
