Description

Technical Field

[0001] This invention relates to the technical field of organic material recycling, and in particular to an organic material recycling device for hydrofluoric acid preparation. Background Technology

[0002] Hydrofluoric acid is an aqueous solution of hydrogen fluoride gas. It is a clear, colorless, fuming, corrosive liquid with a strong, pungent odor. Hydrofluoric acid is a weak acid with extremely strong corrosiveness, capable of severely corroding metals, glass, and silicon-containing materials. During the processing of hydrofluoric acid, it is necessary to mix hydrofluoric acid with other solvents to extract the organic matter, which requires the use of organic material recovery devices.

[0003] In existing organic material recovery devices, there are first filter plates, stirring rods, fixed plates, hydraulic rods, and scrapers. After extraction, the organic matter is easily agglomerated after being cooled by a refrigerator. A second motor drives the stirring rod to break it up, so that smaller organic crystals pass through the first filter plate and fall onto the fixed plate. The hydraulic rod drives the scraper to scrape the smaller organic matter to the second discharge port, while the larger organic matter slides down to the first discharge port for discharge. This facilitates the sorting of organic crystals and makes subsequent processing easier.

[0004] However, in actual processing, using the rotation of the stirring rod to break up organic crystals has a poor breaking effect. Furthermore, when too many crystals accumulate on the filter plate, the stirring rod is prone to jamming. Moreover, when the broken crystals are discharged from the second outlet, blockages are likely to occur, leading to a gradual increase in the amount of crystals accumulating on the filter plate, which will affect the normal recycling of organic materials.

[0033] The following is in conjunction with the appendix Figures 1-10 The present invention will be described in further detail below.

[0034] Reference Figures 1-10This invention discloses an organic material recovery device for hydrofluoric acid preparation, comprising a recovery box body 1, a support base 2, and a filter plate 9. A discharge port is provided on the lower left side of the recovery box body 1. The bottom of the recovery box body 1 is mounted on the support base 2. A feed pipe is connected to one side of the top of the recovery box body 1. An exhaust pipe is connected to the upper part of the inner wall of the rear side of the recovery box body 1. A stirring structure is provided at the top of the recovery box body 1. Feed hoppers 3 are installed on both the left and right sides of the recovery box body 1 near the top, and the feed hoppers 3 are equipped with a material feeding structure. The upper part of the inner walls on both sides of the recycling box 1 is provided with a first feed port 6 that communicates with the top of the feed hopper 3. The middle part of the inner walls on both sides of the recycling box 1 is provided with a second feed port 7 that communicates with the bottom of the feed hopper 3. The inner walls on both sides of the recycling box 1 are provided with a discharge port 4 that is located below the feed hopper 3. The discharge port 4 is provided with an anti-clogging structure. The recycling box 1 is provided with a filtering and crushing structure. The upper part of the recycling box 1 is provided with a partition 5. The top of the inner walls on both sides of the recycling box 1 is provided with a heater.

[0035] The filtration and crushing structure includes an electric telescopic rod 8 installed in the middle of the inner wall of the recycling box 1. A filter plate 9 is installed at the top of the output shaft of the electric telescopic rod 8. The side of the filter plate 9 is close to the inner wall of the recycling box 1. A first fixing plate 10 is provided directly above the filter plate 9. The first fixing plate 10 is fixedly installed on the inner wall of the recycling box 1. The first fixing plate 10 is located between the second feed inlet 7 and the partition 5. Both the first fixing plate 10 and the filter plate 9 are V-shaped. Multiple crushing rods 11 with pointed bottom ends are connected to the bottom of the first fixing plate 10.

[0036] The stirring structure includes a second motor 27 installed on the top of the recycling tank 1. The bottom end of the output shaft of the second motor 27 is connected to a rotating shaft 29 inserted into the recycling tank 1. Multiple stirring rods 28 are connected to the rotating shaft 29. Hydrofluoric acid mixture is added into the recycling tank 1 through the feed pipe. The mixture is heated by a heater, and the second motor 27 is started to drive the rotating shaft 29 and stirring rods 28 to rotate and stir the mixture, causing the mixture to evaporate. Organic crystals are produced on the partition plate 5. Under the action of the feeding structure, the organic crystals are fed into the feed hopper 3, and the crystals are fed onto the filter plate 9 by the feed hopper 3. The electric telescopic rod 8 is started to drive the filter plate 9 to move up and down as a whole, which works with the crushing rod 11 to crush the crystals. The up and down movement of the filter plate 9 can better filter small crystal particles from the filter plate 9, realizing the function of classified collection.

[0037] See Figures 1-3A lifting plate 12 is fixedly installed on the inner wall of the recycling box 1 above the first fixed plate 10. A connecting rod 15 is connected to the middle of the lower part of the lifting plate 12. The connecting rod 15 moves through the bottom end of the first fixed plate 10 and is connected to the filter plate 9. Multiple unblocking blocks 14 are connected to the lower part of the lifting plate 12. The first fixed plate 10 has a through groove 13 for the unblocking blocks 14 to pass through. When the filter plate 9 moves down after the crystal is crushed, it can move the unblocking blocks 14 on the lifting plate 12 down through the first fixed plate 10, thereby unblocking the crystals stuck on the crushing rod 11.

[0038] See Figure 1 , Figure 7 , Figure 8 and Figure 9 The anti-clogging structure includes fixing strips 16 embedded in the lower part of the inner wall on both sides of the discharge port 4. At both ends of each set of two fixing strips 16, there are rotating rods 17. Each set of two rotating rods 17 is fitted with a conveyor belt 18. Multiple anti-clogging plates 19 are connected to the conveyor belt 18. The multiple anti-clogging plates 19 are evenly distributed on the conveyor belt 18. When the rotating rods 17 drive the conveyor belt 18 and the anti-clogging plates 19 to rotate as a whole, large particles of crystal that fall off the filter plate 9 can be sent out from the discharge port 4. In addition, the movement of the anti-clogging plates 19 can also play a role in clearing blockages at the discharge port 4, ensuring the smooth operation of the work.

[0039] A mounting plate 20 is connected to the right side of the front of the recycling bin 1 near the rotating rod 17. A first motor 21 is mounted on the mounting plate 20. A first gear 22 is fitted on the output shaft of the first motor 21. A second gear 23 is fitted on one end of a rotating rod 17 near the first gear 22. The second gear 23 meshes with the first gear 22. A third gear 24 is fitted on one end of the output shaft of the first motor 21. A fourth gear 26 is fitted on one end of another rotating rod 17 near the first motor 21. A transmission belt 25 is fitted on the fourth gear 26 and the third gear 24. The inner wall of the transmission belt 25 is provided with teeth that mesh with the third gear 24 and the fourth gear 26. When the first motor 21 is started, the first gear 22 and the second gear 23 drive one set of rotating rods 17 and the conveyor belt 18 to rotate. Through the third gear 24, the transmission belt 25 and the fourth gear 26, the other set of conveyor belts 18 can be driven to rotate at the same time, realizing the automatic material discharge function.

[0040] See Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 10The feeding structure includes a cylinder 30 installed above the two feed hoppers 3 on opposite sides. The output shaft of the cylinder 30 is inserted into the feed hopper 3 and connected to a feeding plate 31 through a movable connection structure. When the cylinder 30 is activated, it drives the feeding plate 31 to move back and forth, which can pull the crystals on the partition 5 into the feed hopper 3 for feeding. During the heating and stirring process, the activation can drive the feeding plate 31 to move and press against the inner wall of the first feed port 6 to block the feed hopper 3.

[0041] The movable connection structure includes a push-pull block 40 connected to one end of the output shaft of the cylinder 30. U-shaped strips 41 are connected to the edges of both the front and rear sides of the push-pull block 40. A vertical groove 42 is provided on the material-feeding plate 31 for the push-pull block 40 and the U-shaped strips 41 to pass through. A fixing rod 43 is connected between the inner walls of the upper and lower ends of the U-shaped strip 41. Two second springs 44 are sleeved on the fixing rod 43, with both ends of each second spring 44 connected to the U-shaped strip 41 and the material-feeding plate 31 respectively. A rod is fixedly inserted through the material-feeding plate 31 along its length. 32. A second fixing plate 33 is fixedly embedded in the inner walls of both the front and rear sides of the recycling bin 1 at the position of the feeding plate 31. A groove 36 is provided on the second fixing plate 33, and the end of the insertion rod 32 is inserted into the groove 36. Guide plates 34 are provided on both sides of the inner wall of the groove 36, and both ends of the guide plates 34 are inclined. The two guide plates 34 in the groove 36 are symmetrically arranged. Guide grooves 35 are provided on both ends of the groove wall of the groove 36. (The shapes of the groove 36, guide plates 34, and guide grooves 35 are as follows...) Figure 10 As shown), when the starting cylinder 30 moves the material-dispensing plate 31 into the recycling box 1, the sliding of the insert rod 32 on the guide plate 34 can move the material-dispensing plate 31 upward to disengage from the partition plate 5, thus preventing the material-dispensing plate 31 from pushing the crystals back onto the partition plate 5. When the material-dispensing plate 31 moves into the feeding hopper 3, the sliding of the insert rod 32 on the guide plate 34 can move the material-dispensing plate 31 downward to fit onto the partition plate 5, so as to smoothly drag the organic crystals on the partition plate 5 into the feeding hopper 3 for unloading, making the unloading of the crystals on the partition plate 5 more thorough.

[0042] A slot 37 is provided on the bottom surface of the feeding plate 31. A retaining strip 38 is inserted into the slot 37. A first spring 39 is connected between the retaining strip 38 and the upper wall of the slot 37. When the feeding plate 31 moves into the recycling box 1, it can lift the feeding plate 31 and the retaining strip 38 as a whole. When the feeding plate 31 moves into the feed hopper 3, it can drive the retaining strip 38 to press against the partition plate 5, so as to smoothly discharge the material. When one end of the insert rod 32 slides in the guide groove 35, the elastic force of the second spring 44 pushes the retaining strip 38 down to press against the lower inner wall of the first feed port 6, which plays a blocking role at the first feed port 6, preventing the mixed liquid in the recycling box 1 from flowing directly into the feed hopper 3.

[0043] The implementation principle of an organic material recovery device for hydrofluoric acid preparation according to an embodiment of the present invention is as follows: First, hydrofluoric acid mixture is added into the recovery tank 1 through the feed pipe. The heater and the second motor 27 are started. The second motor 27 drives the stirring rod 28 on the rotating shaft 29 to rotate and stir the mixture inside the recovery tank 1. The heater heats the mixture inside the recovery tank 1 to evaporate it, obtaining organic crystals. Then, the cylinder 30 is started to move the feeding plate 31 into the recovery tank 1, opening the feed hopper 3 and driving... The insertion rod 32 slides from the guide groove 35 into the groove 36. Guided by the inclined surface of one end of the guide plate 34, one end of the insertion rod 32 slides on the top of the guide plate 34, causing the material-pulling plate 31 to move upward on the push-pull block 40. This causes the second spring 44 to deform, and also causes the material-pulling plate 31 and the abutment strip 38 to move upward as a whole, separating from the partition plate 5. When the material-pulling plate 31 moves to the end of the groove 36 away from the cylinder 30, the spring of the second spring 44 acts to spring the material-pulling plate 31 and the abutment strip 38 as a whole. After fixing, the cylinder 30 drives the material-pushing plate 31 to move in the opposite direction. Guided by the inclined surface of the other end of the guide plate 34, the insertion rod 32 slides below the guide plate 34, causing the material-pushing plate 31 and the clamping strip 38 to move downward as a whole. This causes the second spring 44 to deform, making the clamping strip 38 stick to the partition 5 and move towards one side of the feed hopper 3, pulling the organic crystals on the partition 5 into the feed hopper 3. The material is then discharged from the feed hopper 3 onto the filter plate 9. Then, the electric telescopic rod 8 is activated to move the filter plate 9 up and down. Organic crystals are driven by filter plate 9 to crush rod 11. Small crystal particles are filtered off filter plate 9, while large crystal particles are shaken off to discharge port 4. At the same time, the first motor 21 is started, driving the two sets of rotating rods 17, conveyor belt 18, and anti-blocking plate 19 to rotate as a whole. This smoothly sends the large organic crystal particles out of discharge port 4 and collects the filtered organic crystals from the discharge port, achieving the function of classified collection. In this way, the recycling of organic materials can be completed.

[0044] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
