Description

Technical Field

[0001] The present invention relates to the technical field of raw material purification, and specifically to a deep eutectic solvent purification device for raw materials produced from waste polyester textiles. Background Art

[0002] The raw materials of waste polyester textiles mainly include polyester fiber textiles, auxiliary materials, impurities, adhesives or binders. After these raw materials are recycled and processed, they can be used to produce new fibers, plastic particles, etc. The purification of the raw materials of waste polyester textiles is mainly used to remove impurities, including dyes, oil stains, additives, impurity fibers, etc. Moreover, purification can improve the purity of recycled polyester and ensure the performance consistency and quality stability of recycled products. The purification by deep eutectic solvent of raw materials refers to using deep eutectic as a solvent to purify the raw materials. This process can help remove impurities and obtain purer raw materials. Therefore, using deep eutectic solvent for purification is a very important purification method.

[0003] A composite plastic paper recycling dissolution and separation device with the patent publication number of CN110000964A heats the air inside the feeding barrel through a heating plate. When the paper attached with plastic enters the feeding barrel, it will deform due to heat, thereby reducing the contact area between the plastic and the paper. After the raw materials enter the dissolution tank, the paper can be quickly dissolved, improving the operation efficiency. The dissolution liquid in the bearing tank is input into the dissolution tank through an input pipe, and at the same time, the dissolution liquid in the dissolution tank is input into the bearing tank through an output pipe, so that the dissolution liquid in the dissolution tank can flow continuously, thus avoiding the phenomenon of accumulation of raw materials in the dissolution tank below the feeding barrel. At the same time, by pressing the raw materials with a pressing plate, the raw materials can be completely immersed in the dissolution liquid, thereby ensuring the dissolution effect on the paper.

[0004] When purifying waste polyester bottle chips with the above and similar technical solutions, the stains on the waste polyester bottle chips will gradually spread throughout the container during the rinsing process and mix with the deep eutectic solvent. When the content of stains in the deep eutectic solvent is relatively high, it will affect the purification result of the waste polyester bottle chips and reduce the purification accuracy of the waste polyester bottle chips. At the same time, due to the different types of impurities on the waste polyester bottle chips, the stains mixed in the deep eutectic solvent will also be different. When recycling, purifying and reusing the deep eutectic solvent, the deep eutectic solvent contains different types of stains. At this time, adopting a fixed distillation temperature is likely to cause side reactions. Summary of the Invention

[0005] The purpose of the present invention is to provide a deep eutectic solvent purification device for raw materials produced from waste polyester textiles, so as to solve the problems raised in the above background art.

[0006] To achieve the above object, the present invention provides the following technical solution: a deep eutectic solvent purification device for the raw materials of waste polyester textiles, including a main body assembly and a rotating assembly for rinsing waste polyester bottle chips. A bearing assembly for storing waste polyester bottle chips is arranged in the rotating assembly. An emission assembly for discharging the deep eutectic solvent is arranged on the main body assembly. A shaking assembly for accelerating purification and an impact assembly for screening the deep eutectic solvent are arranged on the rotating assembly; The main body assembly includes a main cylinder and a main shaft arranged in the main cylinder. The rotating assembly includes a rotating cylinder arranged on the main shaft. The bearing assembly includes a plurality of bearing boxes arranged in the rotating cylinder. A driving motor for driving the rotating cylinder to rotate is arranged at the bottom of the main cylinder. A plurality of first through holes are formed in the rotating cylinder, and a plurality of second through holes corresponding to the first through holes are formed in the bearing boxes. The emission assembly includes a first absorption plate and a second absorption plate, which are respectively arranged above and below the main shaft; Deep eutectic solvent is poured into the main cylinder, and the waste polyester bottle chips to be purified are placed in the bearing box. The driving motor drives the rotating cylinder to rotate, and the deep eutectic solvent enters the bearing box through the first through hole and the second through hole to purify the waste polyester bottle chips. The deep eutectic solvent doped with impurities enters the rotating cylinder through the second through hole. The deep eutectic solvents doped with different impurities have different densities and are respectively located in the upper and lower layers of the rotating cylinder, and are respectively absorbed by the first absorption plate and the second absorption plate.

[0007] Furthermore, a guide plate is arranged on the rotating cylinder, and the guide plate respectively covers the surface of the first through hole. The guide plate is an arc-shaped semi-sealed structure. The rotating cylinder rotates counterclockwise, and the guide plate guides the deep eutectic solvent in the main cylinder into the rotating cylinder to prevent the deep eutectic solvent mixed with impurities from overflowing from the first through hole.

[0008] Furthermore, a first limiting ring and a second limiting ring are respectively arranged in the main cylinder. The first limiting ring and the second limiting ring are rotationally connected with the main shaft. A plurality of guide vanes are fixedly connected to the top of the main shaft. When the main shaft rotates, the guide vanes rotate simultaneously with the main shaft, generating a downward guiding force on the deep eutectic solvent in the main cylinder to prevent the deep eutectic solvent mixed with impurities from overflowing from the top of the bearing box.

[0009] Furthermore, a plurality of top plates are arranged on the top of the rotating cylinder, a plurality of clamping blocks are arranged on the top plates, a plurality of clamping grooves adapted to the clamping blocks are formed in the bearing box, and a pull rod is arranged on the bearing box. The bearing box is taken and placed through the pull rod, the bearing box is limited through the clamping block, and the deep eutectic solvent doped with impurities entering the rotating cylinder through the second through hole is in the adjacent area of the bearing box.

[0010] Furthermore, the impact assembly includes a plurality of rotating disks. The rotating disks are arranged at the bottom of the rotating cylinder. The rotating disks are connected to the rotating cylinder by sealed bearings. Impact vanes are arranged on the rotating disks. Driving disks are fixedly connected to the bottoms of the rotating disks. A fixed gear ring is arranged at the bottom of the main cylinder. The driving disks are engaged with the fixed gear ring. When the rotating cylinder rotates, the rotating disks rotate simultaneously with the rotating cylinder and rotate self-driven under the action of the fixed gear ring, driving the rotating disks to rotate. The impact vanes rotate with the rotation of the rotating disks, generating an upward impact force to impact the deep eutectic solvent mixed with impurities, promoting the stratification of the deep eutectic solvent.

[0011] Furthermore, the shaking assembly includes a shaking plate. The shaking plate is arranged at the bottom of the bearing box. A bottom plate is fixed to the bottom of the bearing box. A return spring is fixedly connected between the bottom plate and the shaking plate. A lifting rod is arranged at the bottom of the shaking plate. The bottom of the lifting rod is arranged in an inclined structure. A fixing plate is arranged at the bottom of the main cylinder. A plurality of guiding platforms are arranged on the fixing plate. The tops of the guiding platforms are all arranged in an inclined structure. Ball bearings are arranged on the tops of the guiding platforms. When the bearing box rotates with the rotation of the rotating cylinder, it will drive the lifting rod to rotate and make the lifting rod contact with the guiding platforms in turn. Since the bottoms of the lifting rods and the tops of the guiding platforms are both arranged in an inclined structure, the guiding platforms will cause the lifting rods to rise and drive the shaking plate to shake, accelerating the purification of waste polyester bottle chips. The ball bearings reduce the wear between the lifting rods and the guiding platforms.

[0012] Furthermore, a first confluence pipe and a second confluence pipe are arranged in the main shaft. The first absorption plate communicates with the first confluence pipe. The second absorption plate communicates with the second confluence pipe. A discharge platform is arranged on the main cylinder. A connecting pipe is arranged on the discharge platform. The connecting pipe communicates with the first confluence pipe and the second confluence pipe respectively. A discharge head is arranged on the discharge platform. The upper first absorption plate absorbs the deep eutectic solvent with low density doped with impurities. The lower second absorption plate absorbs the deep eutectic solvent with high density doped with impurities, which are respectively transported to the discharge platform through the first confluence pipe and the second confluence pipe and are independently discharged through the discharge head.

[0013] Furthermore, a rotating gear disk is arranged at the bottom of the main shaft. The driving motor is fixed to the bottom of the fixing plate. One end of the output shaft of the driving motor is provided with a main gear disk engaged with the rotating gear disk. When the driving motor starts, it drives the main gear disk to rotate, further driving the rotating gear disk and the main shaft to rotate.

[0014] Furthermore, a feed pipe is arranged at the top of the main cylinder.

[0015] Compared with the prior art, the beneficial effects of the present invention are: The deep eutectic solvent purification device for the raw materials of waste polyester textiles, through the rotation of the rotating cylinder, the deep eutectic solvent on the periphery of the main cylinder will enter the bearing box through the first through hole and the second through hole, and pour the deep eutectic solvent that has undergone the purification reaction in the bearing box into the adjacent area of the bearing box. Since the deep eutectic solvents doped with different impurities have different densities, the deep eutectic solvent with a smaller density will float on the upper half, and the deep eutectic solvent with a larger density will sink to the bottom. At this time, the first absorption plate and the second absorption plate located on the upper and lower layers of the rotating cylinder will respectively absorb the deep eutectic solvent with a smaller density and the deep eutectic solvent with a larger density, thus realizing the screening and absorption effect of the deep eutectic solvent, and at the same time preventing the deep eutectic solvent from overflowing to the periphery of the main cylinder, ensuring the purity of the deep eutectic solvent.

[0016] At the same time, when the rotating cylinder rotates, under the action of the fixed gear ring, the rotating disk is driven to rotate, and the impact blades rotate with the rotation of the rotating disk, generating an upward impact force to impact the deep eutectic solvent mixed with impurities. Under the action of the impact force, the deep eutectic solvent with a smaller density floats on the upper half at a faster speed, and the intensity of the impact force is relatively low and will not affect the automatic sinking of the deep eutectic solvent with a larger density. Therefore, it can promote the stratification of the deep eutectic solvent. Brief Description of the Drawings

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Deep eutectic solvents are widely used in the purification process of waste PET bottle chips. However, stains will spread throughout the solvent system during the rinsing process and mix with the deep eutectic solvents, thus affecting the purification effect and the recycling of deep eutectic solvents. When using deep eutectic solvents to purify waste PET bottle chips, the stains fall off the bottle chip surface and spread in the rinsing solution. When the stain concentration in the deep eutectic solvent is high, it will interfere with the dissolution, washing, and separation processes of PET. The stains may interact with PET molecules to form complexes that are difficult to remove, thereby affecting the purity of PET. In particular, some pigment and glue residues are extremely difficult to separate from PET, which will lead to a decrease in the hue and transparency of recycled PET and reduce its application value. Moreover, the stains may reduce the dissolution ability of deep eutectic solvents for PET, prolong the purification time, and increase energy consumption. Secondly, due to the wide sources of waste PET bottle chips and the variety of impurities, the stains mixed in the deep eutectic solvents are also different. Traditional solvent purification methods such as distillation often have difficulty effectively removing all types of stains, especially when the deep eutectic solvent contains multiple complex components. Different types of stains have different thermal stabilities, and some stains may undergo decomposition, polymerization, or carbonization reactions at the distillation temperature, generating new impurities and increasing the difficulty of purification. However, for the technical solution provided in this application, through the purification reaction between the deep eutectic solvent and the waste polyester bottle chips, since the deep eutectic solvents doped with different impurities have different densities, the deep eutectic solvent with a smaller density will float on the upper part, and the deep eutectic solvent with a larger density will sink to the bottom. At this time, the first absorption plate and the second absorption plate at different heights will respectively absorb the deep eutectic solvent with a smaller density and the deep eutectic solvent with a larger density, thus achieving the screening and absorption effect of the deep eutectic solvent and preventing the deep eutectic solvent from overflowing to the periphery, ensuring the purity of the deep eutectic solvent.

[0021] Device for purifying deep eutectic solvent as raw material for producing waste polyester textiles, such as Figure 1-10As shown in the figure, it includes a main body component 1 and a rotating component 3 for rinsing waste polyester bottle chips. A loading component 4 for storing waste polyester bottle chips is arranged in the rotating component 3. An emission component 2 for discharging deep eutectic solvent is arranged on the main body component 1. A shaking component 5 for accelerating purification and an impact component 6 for screening deep eutectic solvent are arranged on the rotating component 3. The main body component 1 includes a main cylinder 101 and a main shaft 105 arranged inside the main cylinder 101. The rotating component 3 includes a rotating cylinder 301, and the rotating cylinder 301 is arranged on the main shaft 105. The loading component 4 includes a plurality of loading boxes 401, and the loading boxes 401 are arranged inside the rotating cylinder 301. A driving motor 306 for driving the rotation of the rotating cylinder 301 is arranged at the bottom of the main cylinder 101. A plurality of first through holes 305 are formed on the rotating cylinder 301, and a plurality of second through holes 403 corresponding to the first through holes 305 are formed on the loading boxes 401. The emission component 2 includes a first absorption plate 204 and a second absorption plate 205, and the first absorption plate 204 and the second absorption plate 205 are respectively arranged above and below the main shaft 105. Deep eutectic solvent is poured into the main cylinder 101, and the waste polyester bottle chips to be purified are put into the loading boxes 401. The driving motor 306 drives the rotation of the rotating cylinder 301, and the deep eutectic solvent enters the loading boxes 401 through the first through holes 305 and the second through holes 403 to purify the waste polyester bottle chips. The deep eutectic solvent doped with impurities enters the rotating cylinder 301 through the second through holes 403. The deep eutectic solvents doped with different impurities have different densities and are respectively located in the upper and lower layers of the rotating cylinder 301, and are respectively absorbed by the first absorption plate 204 and the second absorption plate 205.

[0022] It should be noted that after pouring deep eutectic solvent into the main cylinder 101, the waste polyester bottle chips are put into the loading boxes 401, and the loading boxes 401 are put into the rotating cylinder 301. The loading boxes 401 are distributed diagonally, so there will be gaps in the adjacent areas of the loading boxes 401. Since the main cylinder 101 is filled with deep eutectic solvent, and the deep eutectic solvent will purify the waste polyester bottle chips. At this time, with the rotation of the rotating cylinder 301, the deep eutectic solvent on the periphery of the main cylinder 101 will enter the loading boxes 401 through the first through holes 305 and the second through holes 403, and the deep eutectic solvent that has undergone purification reaction in the loading boxes 401 will be poured into the adjacent areas of the loading boxes 401. Since the deep eutectic solvents doped with different impurities have different densities, the deep eutectic solvent with a smaller density will float on the upper part, and the deep eutectic solvent with a larger density will sink to the bottom. At this time, the first absorption plate 204 and the second absorption plate 205 respectively located in the upper and lower layers of the rotating cylinder 301 will respectively absorb the deep eutectic solvent with a smaller density and the deep eutectic solvent with a larger density, thus realizing the screening and absorption effect of the deep eutectic solvent, and at the same time preventing the deep eutectic solvent from overflowing to the periphery of the main cylinder 101 and ensuring the purity of the deep eutectic solvent.

[0023] AsFigure 3 and Figure 5 As shown in Figure 5 , a guide plate 302 is provided on the rotating cylinder 301. The guide plate 302 covers the surface of the first through hole 305 respectively. The guide plate 302 is an arc-shaped semi-sealed structure. The rotating cylinder 301 rotates counterclockwise, and the guide plate 302 guides the deep eutectic solvent in the main cylinder 101 into the rotating cylinder 301.

[0024] It should be noted that since the guide plate 302 is an arc-shaped semi-sealed structure with one end open and the upper, lower and the other end sealed, when the rotating cylinder 301 rotates counterclockwise, the deep eutectic solvent will enter the first through hole 305 from the open end of the guide plate 302, and the deep eutectic solvent that has undergone the purification reaction will be poured into the adjacent area of the carrier box 401 through the second through hole 403, preventing the deep eutectic solvent mixed with impurities from overflowing from the first through hole 305.

[0025] As Figure 2 and Figure 3 shown, a first limiting ring 103 and a second limiting ring 104 are respectively provided in the main cylinder 101. The first limiting ring 103 and the second limiting ring 104 are rotationally connected to the main shaft 105. A plurality of guide vanes 304 are fixedly connected to the top of the main shaft 105.

[0026] It should be noted that when the main shaft 105 rotates, the guide vanes 304 rotate simultaneously with the main shaft 105. Since the main cylinder 101 is filled with deep eutectic solvent, the inclined guide vanes 304 will generate a downward guiding force on the deep eutectic solvent in the main cylinder 101, and the deep eutectic solvent is used to pour the deep eutectic solvent that has undergone the purification reaction into the adjacent area of the carrier box 401 through the second through hole 403, preventing the deep eutectic solvent mixed with impurities from overflowing from the top of the carrier box 401.

[0027] As Figure 6 shown, a plurality of top plates 303 are provided on the top of the rotating cylinder 301. A plurality of clamping blocks are provided on the top plates 303. A plurality of clamping grooves adapted to the clamping blocks are formed on the carrier box 401. A pull rod 402 is provided on the carrier box 401.

[0028] It should be noted that the carrier box 401 can be pulled out from the rotating cylinder 301 and is aligned and limited under the action of the clamping blocks. The carrier box 401 is taken and placed through the pull rod 402, and the carrier box 401 is limited through the clamping blocks. The deep eutectic solvent doped with impurities that enters the rotating cylinder 301 through the second through hole 403 is in the adjacent area of the carrier box 401.

[0029] As Figure 4 、 Figure 6 、 Figure 8-Figure 9As shown, the impact assembly 6 includes a plurality of rotating disks 601. The rotating disks 601 are arranged at the bottom of the rotating cylinder 301. The rotating disks 601 are connected to the rotating cylinder 301 by sealed bearings. Impact vanes 602 are arranged on the rotating disks 601. Driving disks 604 are fixedly connected to the bottoms of the rotating disks 601. A fixed gear ring 603 is arranged at the bottom of the main cylinder 101. The driving disks 604 are engaged with the fixed gear ring 603.

[0030] It should be noted that when the rotating cylinder 301 rotates, the rotating disks 601 rotate simultaneously with the rotating cylinder 301 and rotate self - clockwise under the action of the fixed gear ring 603, driving the rotating disks 601 to rotate. The impact vanes 602 rotate with the rotation of the rotating disks 601, generating an upward impact force to impact the deep eutectic solvent mixed with impurities. Since the deep eutectic solvents doped with different impurities have different densities, the deep eutectic solvents with smaller densities will float in the upper part, and the deep eutectic solvents with larger densities will sink to the bottom. Therefore, under the action of the impact force, the deep eutectic solvents with smaller densities float in the upper part at a faster speed, and the intensity of the impact force is relatively low and will not affect the automatic sinking of the deep eutectic solvents with larger densities. Therefore, the stratification of the deep eutectic solvent can be promoted.

[0031] As Figure 7 , Figure 9-Figure 10 As shown, the jitter assembly 5 includes a jitter plate 501. The jitter plate 501 is arranged at the bottom of the bearing box 401. A bottom plate 404 is fixed to the bottom of the bearing box 401. A return spring 503 is fixedly connected between the bottom plate 404 and the jitter plate 501. A lifting rod 502 is arranged at the bottom of the jitter plate 501. The bottom of the lifting rod 502 is set as an inclined structure. A fixing plate 504 is arranged at the bottom of the main cylinder 101. A plurality of guiding platforms 505 are arranged on the fixing plate 504. The tops of the guiding platforms 505 are all set as inclined structures. Ball bearings 506 are arranged on the tops of the guiding platforms 505.

[0032] It should be noted that when the bearing box 401 rotates with the rotation of the rotating cylinder 301 and further drives the lifting rod 502 to rotate, and when the lifting rod 502 rotates, it will come into contact with the guiding platforms 505 in sequence. Since the bottom of the lifting rod 502 and the tops of the guiding platforms 505 are both set as inclined structures, when the lifting rod 502 contacts the guiding platforms 505, the guiding platforms 505 will cause the lifting rod 502 to rise under the extrusion force and drive the jitter plate 501 to rise. When the lifting rod 502 misses the contact with the guiding platforms 505, under the action of the return spring 503, the jitter plate 501 will be pulled down. Thus, during the rotation of the rotating cylinder 301, the jitter plate 501 will vibrate in a reciprocating up - and - down manner, accelerating the purification of waste polyester bottle chips. The ball bearings 506 reduce the wear between the lifting rod 502 and the guiding platforms 505.

[0033] As Figure 2 , Figure 6and Figure 8 As shown in Figure 8 , a first confluence pipe 206 and a second confluence pipe 207 are arranged in the main shaft 105. The first absorption plate 204 communicates with the first confluence pipe 206, and the second absorption plate 205 communicates with the second confluence pipe 207. A discharge platform 201 is arranged on the main cylinder 101, a connecting pipe 203 is arranged on the discharge platform 201, the connecting pipe 203 communicates with the first confluence pipe 206 and the second confluence pipe 207 respectively, and a discharge head 202 is arranged on the discharge platform 201.

[0034] It should be noted that due to the different densities of deep eutectic solvents doped with different impurities, the deep eutectic solvent with a smaller density will float in the upper part, and the deep eutectic solvent with a larger density will sink to the bottom. Therefore, the upper first absorption plate 204 will absorb the deep eutectic solvent doped with impurities with a small density, and the lower second absorption plate 205 will absorb the deep eutectic solvent doped with impurities with a large density, and they will be respectively transported to the discharge platform 201 through the first confluence pipe 206 and the second confluence pipe 207, and further independently discharged through the discharge head 202. At this time, the types of pollutants in the discharged deep eutectic solvent are different, and different recovery schemes can be adopted, which is more convenient for recovery.

[0035] As Figure 5 、 Figure 9-Figure 10 As shown in Figure 9-Figure 10 , a rotating gear disk 308 is arranged at the bottom of the main shaft 105, the driving motor 306 is fixed at the bottom of the fixing plate 504, and a main gear disk 307 meshing with the rotating gear disk 308 is arranged at one end of the output shaft of the driving motor 306.

[0036] It should be noted that when the driving motor 306 starts, it drives the main gear disk 307 to rotate, and further drives the rotating gear disk 308 and the main shaft 105 to rotate.

[0037] As Figure 1 As shown in Figure 1 , a feed pipe 102 is arranged at the top of the main cylinder 101.

[0038] It should be noted that deep eutectic solvent can be added into the main cylinder 101 through the feed pipe 102, and a discharge valve is also arranged on the main cylinder 101. Through the discharge valve, the deep eutectic solvent in the main cylinder 101 can be thoroughly cleaned, which is convenient for cleaning the equipment.

[0039] It should be noted that the deep eutectic solvent can be added into the main cylinder 101 through the feed pipe 102. After filling the deep eutectic solvent into the main cylinder 101, the waste polyester bottle chips are placed in the carrier box 401, and the carrier box 401 is placed into the rotating cylinder 301. The deep eutectic solvent will purify the waste polyester bottle chips. The driving motor 306 is started to drive the main gear disk 307 to rotate, further driving the rotating gear disk 308 and the main shaft 105 to rotate. The deep eutectic solvent outside the main cylinder 101 will enter the carrier box 401 through the first through hole 305 and the second through hole 403, and pour the deep eutectic solvent that has undergone the purification reaction in the carrier box 401 into the adjacent area of the carrier box 401. When the rotating cylinder 301 rotates counterclockwise, the deep eutectic solvent will enter the first through hole 305 from the opening of the guide plate 302, and pour the deep eutectic solvent that has undergone the purification reaction into the adjacent area of the carrier box 401 through the second through hole 403. The first absorption plate 204 and the second absorption plate 205 located in the upper and lower layers of the rotating cylinder 301 will absorb the deep eutectic solvent with a smaller density and the deep eutectic solvent with a larger density respectively, and are transported to the discharge platform 201 through the first confluence pipe 206 and the second confluence pipe 207 respectively, and are further independently discharged through the discharge head 202. When the main shaft 105 rotates, the guide vane 304 rotates simultaneously with the main shaft 105. Since the main cylinder 101 is filled with the deep eutectic solvent, the inclined guide vane 304 will generate a downward guiding force on the deep eutectic solvent in the main cylinder 101. When the rotating cylinder 301 rotates, the rotating disk 601 rotates simultaneously with the rotating cylinder 301 and rotates around its own axis under the action of the fixed gear ring 603, driving the rotating disk 601 to rotate. The impact vane 602 rotates with the rotation of the rotating disk 601, generating an upward impact force to impact the deep eutectic solvent mixed with impurities. The carrier box 401 will rotate with the rotation of the rotating cylinder 301, and further drive the lifting rod 502 to rotate. When the lifting rod 502 rotates, it will contact the guide platform 505 in turn, and the shaking plate 501 will shake in a reciprocating up-and-down manner, accelerating the purification of the waste polyester bottle chips. The ball 506 reduces the wear between the lifting rod 502 and the guide platform 505.
