Abstract
Description
Technical Field
[0001] This invention belongs to the field of waste solvent recycling and treatment technology, specifically an organic waste solvent recycling and treatment device. Background Technology
[0002] In the automotive painting process, after applying the clear coat, it is essential to clean the spray guns, paint lines, and automatic painting equipment with organic solvents to prevent residual paint from hardening and clogging the equipment. This process generates waste solvents containing volatile organic compounds (VOCs) such as benzene, toluene, xylene, and acetone. These solvents are not only flammable and explosive but also highly toxic. Long-term exposure may damage the respiratory tract, nervous system, and skin health, and may even cause chronic poisoning. Cleaning the waste solvents requires hazardous waste disposal, and the cleaning agents used are also a significant expense. In existing technologies, waste solvents are usually purified by distillation and recycled. However, since waste solvents contain a large amount of resin, curing agent and their cross-linking products, direct distillation or slurrying results in low purification efficiency and poor quality. Furthermore, the solid residues (paint residue, solid particles, etc.) and clarified liquid separated from the waste solvents are still harmful substances and cannot be directly discharged. In addition, the solid residues need to be processed through multiple purification equipment, making the entire recycling and purification process too time-consuming. Moreover, residues are easily left in the sedimentation and separation tank.
[0003] Therefore, a new design is needed that can improve recycling efficiency and minimize residue. Summary of the Invention

[0008] Preferably, the inner wall of the support plate and the residue tank are fixedly connected, and a T-shaped rod is eccentrically fixedly connected to the top of the tooling wheel away from the motor. A rectangular groove plate is slidably connected between the T-shaped rod and the outer wall of the tooling wheel top away from the motor. A crossbar is fixedly connected to the outer walls of both ends of the rectangular groove plate, and an L-shaped stirring rod is fixedly connected to the body of each of the two crossbars. A stirring head is fixedly connected to the bottom end of each of the two L-shaped stirring rods.
[0009] Preferably, each of the two L-shaped stirring rods is fixedly connected to an L-shaped bracket, and two long sliding grooves are provided on the top tank body and the support plate of the residue tank. The two long sliding grooves on the support plate are in close contact with the two L-shaped stirring rods, and the two long sliding grooves on the top tank body of the residue tank are in close contact with the two L-shaped brackets. An electric heating tube is fixedly connected to the inner wall of the residue tank to keep the inside of the residue tank at a high temperature. A conical cover is also fixedly connected to the plate of the support plate. The belt in the synchronous belt and the rods of the two crossbars all pass through the conical cover, and the two crossbars and the belt are slidably connected to the conical cover.
[0010] Preferably, the translational top conveying structure includes a double-headed inclined plate fixedly connected to the L-shaped bracket. Both the upper and lower ends of the double-headed inclined plate are fitted with arc-shaped plates. A striking rod is fixedly connected to one of the opposite symmetrical ends of the two arc-shaped plates.

[0014] Preferably, both the waste solvent tank and the residue tank are fixedly connected to the bottom of the tank body with support brackets.
[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention incorporates a guide plate and a baffle plate within the separation tank. The guide plate ensures a smooth and rapid flow of waste solvent, quickly introducing it into a laminar flow state and preventing eddies / turbulent flow from carrying away residues. This guarantees effective gravity settling from the source. The baffle plate divides the separation tank into a sedimentation zone and a clarification zone. In conjunction with the semi-circular filter plate in the clarification zone, the rising clarified liquid undergoes secondary sieving, effectively preventing fine particulate impurities from flowing out with the clarified liquid. This significantly improves the purity of the recovered clarified liquid, laying a high-quality raw material foundation for subsequent solvent distillation and regeneration. This invention employs an integrated grinding and extraction processing structure for the separated solid residue. First, the residue is ground and crushed by an eccentrically rotating grinding rod and then precisely sieved through a grinding sieve plate to ensure that the residue particles meet the standard specifications, significantly increasing the contact area between the residue and the extractant. Simultaneously, an electric heating tube is installed in the residue tank to provide a high-temperature environment. Combined with the reciprocating translational stirring of the L-shaped stirring rod, the adsorbed / encapsulated organic solvent in the residue is fully dissolved into the extractant under the principle of "like dissolves like," significantly improving the extraction and recovery efficiency of the organic solvent, realizing the resource regeneration of waste solvent, improving resource utilization, and reducing treatment costs. This invention uses an L-shaped bracket to drive a double-headed inclined panel, an arc panel, and a striking rod to form an automated tank impact vibration mechanism. Without the need for additional power equipment, it can achieve synchronous impact vibration on the bottom of the separation tank and the sides of the residue tank. The vibration force can effectively break the adhesion and friction between the residue and the tank wall, causing the attached / accumulated residue to fall off quickly and converge towards the slag discharge port. This completely solves the industry problem of easy residue adhesion in the conical section and dead corner of the conical tank / separation tank, greatly reducing the frequency and operational risks of manual cleaning in confined spaces, and reducing equipment maintenance time and costs.

[0018] 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.
[0019] like Figures 1 to 8 As shown, the present invention provides an organic waste solvent recycling and treatment device, including a waste solvent tank 1, a pneumatic diaphragm pump 101, and a separation tank 104. A suction pipe 102 and a delivery pipe 103 are respectively installed on the pump body of the pneumatic diaphragm pump 101. The pipe bodies of the suction pipe 102 and the delivery pipe 103 away from the pneumatic diaphragm pump 101 are respectively fixedly connected to the waste solvent tank 1 and the separation tank 104. A partition 105 is fixedly connected in the inner wall of the separation tank 104. The partition 105 is used to separate the solid residue and the clarified liquid in the waste solvent. A semi-circular filter plate 107 for filtering the clarified liquid is fixedly connected below the side of the partition 105 away from the delivery pipe 103. A purification treatment section 2 is provided below the separation tank 104. A residue tank 201 is provided in the purification treatment section 2. An observation window is installed on the tank body of the separation tank 104. A guide plate 106 is fixedly connected to one end of the transfer pipe 103 located in the inner wall of the separation tank 104, which is used to smoothly discharge the waste solvent passing through the transfer pipe 103. A liquid guide pipe 108 is fixedly connected to the tank body of the separation tank 104 and the transfer pipe 103, which are symmetrically positioned. An inclined pipe is fixedly connected to the bottom conical tank body of the separation tank 104, and a water valve for discharging waste liquid is also fixedly connected to the inclined pipe body. A clarified liquid recovery tank 109 is provided below the liquid guide pipe 108. One-way valves for controlling the unidirectional flow of fluid are installed on the suction pipe 102, the transfer pipe 103 and the guide plate 106. The bottom tank bodies of the waste solvent tank 1 and the residue tank 201 are fixedly connected to the support frame.
[0020] The above solution is adopted: such as Figure 1 and Figure 2 , Figure 3As shown, by starting the pneumatic diaphragm pump 101, the waste solvent in the waste solvent tank 1 is drawn through the suction pipe 102, and then introduced into the separation tank 104 through the delivery pipe 103. The guide plate 106 installed in the separation tank 104 allows the waste solvent to flow into the separation tank 104 smoothly. The waste solvent flows from the top of the separation tank 104 into the settling area, rather than directly into the tank. The tank space is used to achieve a sudden drop in flow velocity, avoiding the disturbance of the liquid phase in the tank by the eddies and turbulence formed by the high-speed fluid. This allows the waste solvent to quickly enter the laminar flow state (low-speed, stable flow state). Turbulence will cause the residue that has already begun to settle to be re-entrained by the liquid flow, while laminar flow can ensure that the residue continues to settle stably under the action of gravity. This is the key prerequisite for gravity settling (the settling process is most afraid of liquid flow disturbance). The waste solvent entering separator 104 causes a significant density difference between the clarified liquid phase (organic solvent mixture) and the solid residue (paint residue, solid particles, etc.) (the residue density is much greater than that of the organic solvent). When the waste solvent is in a low-speed, stable flow state, gravity will create a "separation force" on substances of different densities. Under the action of gravity, the solid residue overcomes the buoyancy and viscous resistance of the organic solvent and undergoes accelerated downward settling motion, eventually settling in the sludge zone at the bottom of the equipment. The less dense clarified liquid is affected by gravity. The small volume of liquid, combined with the spatial displacement effect of the sinking residue, creates a slow upward flow, ultimately achieving solid-liquid separation. The baffle 105 installed in the separation tank 104 divides the tank into two parts: a waste solvent flow sedimentation zone and a clarification zone. When the separated clarified liquid is in the clarification zone, it is also screened by the semi-circular filter plate 107 installed on the baffle 105 to prevent particulate impurities from moving upward with the clarified liquid. Finally, the liquid guide pipe 108 guides the liquid into the clarified liquid recovery tank 109 for collection. When the waste solvent undergoes precipitation to separate solids and liquids, the solid residue will settle to the bottom of the separator 104 by gravity. After all the clarified liquid is discharged, the waste liquid in the same chamber as the solid residue can be discharged directly through the inclined pipe by manually opening the water valve installed on the inclined pipe. This avoids the waste liquid carrying too much waste liquid affecting the extraction effect when the sludge is discharged later. The observation window installed on the separator 104 is used to observe the accumulation position of the sludge. When the sludge reaches the upper limit of the observation window, the solenoid valve installed at the bottom of the separator 104 is opened to discharge the sludge to the lower limit of the observation window.
[0021] like Figure 4 and Figure 5 , Figure 6 , Figure 9As shown, the purification treatment unit 2 includes a grinding disc 208 disposed inside the residue tank 201 for holding solid residue. A support disc 209 is fixedly connected to the bottom of the grinding disc 208. A grinding rod 207 is rotatably connected to the grinding disc 208 and the support disc 209 for crushing the solid residue. A grinding sieve plate is fixedly connected to the center of the support disc 209 for directly feeding the qualified ground solid residue. Below the separator 104 is a drive structure that drives the grinding rod 207 to rotate eccentrically. The drive structure has two translational top conveying structures to cause the separator 104 and the residue tank 201 to vibrate. The residue tank 201 has a material plug tightly clamped to its body. A motor 202 is fixedly connected to the body of the residue tank 201 near the top. A synchronous belt 203 is fixedly connected to the output shaft of the motor 202. The synchronous belt 203 consists of two tooling wheels and a belt that fits and connects to the two tooling wheels. The belt passes through the body of the residue tank 201 and is slidably connected to the belt and the residue tank 201. A rotating rod 204 is fixedly connected to the bottom end of the tooling wheel away from the motor 202. A support plate 205 passes through the rod body of the rotating rod 204. The rotating rod 204 and the support plate 205 are rotatably connected. The plate body of the support plate 205 is fixedly connected to the inner wall of the residue tank 201. A bending plate 206 is fixedly connected to the bottom end of the rotating rod 204. The grinding rod 207 is fixedly connected to one side of the bending plate 206. The support plate 209 is fixedly connected to the inner wall of the residue tank 201.
[0022] A T-shaped rod 210 is eccentrically fixed to the top of the tooling wheel away from the motor 202. A rectangular groove plate 211 is slidably connected between the T-shaped rod 210 and the outer wall of the tooling wheel top away from the motor 202. A crossbar 212 is fixedly connected to the outer wall of both ends of the rectangular groove plate 211. An L-shaped stirring rod 213 is fixedly connected to the body of each of the two crossbars 212. An L-shaped bracket 214 is fixedly connected to the body of each of the two L-shaped stirring rods 213.
[0023] The top tank body of the residue tank 201 and the support plate 209 are both provided with two long sliding grooves 215. The two long sliding grooves 215 on the support plate 209 are in close contact with two L-shaped stirring rods 213. The two L-shaped stirring rods 213 are fixedly connected to the bottom end of the support plate 209. The two long sliding grooves 215 on the top tank body of the residue tank 201 are in close contact with two L-shaped supports 214. The two L-shaped supports 214 extend from the long sliding grooves 215 on the top of the residue tank 201 to the outside of the residue tank 201.
[0024] An electric heating tube is fixedly connected to the inner wall of the residue tank 201 to keep the inside of the residue tank 201 at a high temperature. It should be noted that the high temperature described in this embodiment refers to a temperature suitable for grinding waste residue, not an extremely high temperature that could damage the internal parts of the residue tank 201.
[0025] A conical cover is also fixedly connected to the plate body of the support plate 205. The tooling wheel for connecting the timing belt 203 and the various components on the tooling wheel are all located below the conical cover. The belt in the timing belt 203 and the rods of the two crossbars 212 pass through the conical cover, and the two crossbars 212 and the belt are slidably connected to the conical cover.
[0026] Using the above scheme: the discharged solid residue (the sludge in the separator 104 is not completely discharged) will fall into the residue tank 201, and the falling sludge will enter the grinding disc 208 after passing through the conical hood set in the residue tank 201. like Figure 5 and Figure 6 As shown, the starting motor 202 drives the two tooling pulleys and belt in the synchronous belt 203 to rotate, thereby driving the rotating rod 204 and the bending plate 206 to rotate synchronously. The rotating bending plate 206 drives the connected grinding rod 207 to rotate eccentrically in the grinding disc 208, thus grinding and crushing the sediment in the grinding disc 208. The crushed sediment is directly screened through the grinding screen plate installed on the support plate 209, ensuring that the sediment particles meet the standard crushing specifications, and then discharged into the residue tank 201. The sediment particles will be mixed with the same clean organic solvent (such as using fresh acetone to extract waste acetone residue) placed in the tank. The sediment particles are crushed and ground to increase the contact area with the extractant (organic solvent). The electric heating tube installed in the inner wall of the residue tank 201 is started together with the motor 202 to keep the residue tank 201 at a high temperature so that the waste solvent in the sediment can be fully dissolved in the extractant. Through the principle of "like dissolves like", the waste solvent such as acetone and xylene adsorbed / encapsulated in the solid residue is extracted, realizing the recycling and regeneration of organic solvent.
[0027] During the passive transmission process of the synchronous belt 203, the T-shaped rod 210 fixed on the tool wheel will also rotate. The T-shaped rod 210 slides against the inner wall of the rectangular groove plate 211 in a passive state, causing the rectangular groove plate 211 to move horizontally back and forth. This drives the horizontal bar 212 and L-shaped stirring rod 213 installed at both ends to move horizontally back and forth. The passive movement of the L-shaped stirring rod 213 will cause the fixed L-shaped bracket 214 to move synchronously. The passive movement of the L-shaped stirring rod 213 and the L-shaped bracket 214 will pass through the long sliding groove 215 opened on the residue tank 201 and the support plate 209, which will guide the translation. Then, the passively reciprocating L-shaped stirring rod 213 and the stirring head fixed at the bottom will stir and mix the solid particle residue and the extractant, so that the waste solvent in the residue can be fully dissolved into the extractant.
[0028] The horizontal conveying structure includes a double-headed inclined plate 216 fixedly connected to an L-shaped bracket 214. Arc-shaped plates 217 are fitted onto both the upper and lower ends of the double-headed inclined plate 216. A striking rod 218 is fixedly connected to the opposite symmetrical end of each of the two arc-shaped plates 217. The upper striking rod 218 can be fitted to the bottom of the separation tank 104, and the lower striking rod 218 can be fitted to the side of the residue tank 201. The arc-shaped plates 217 are fixed with… A T-shaped block 219 is connected to the tank body of the separation tank 104. A rod seat 110 is fixedly connected to the rod body on both sides of the rod seat 110. T-shaped T-slot plates 220 are fixedly connected to the T-shaped block 219. A spring 221 is fixedly connected between the T-shaped block 219 and the T-shaped T-slot plate 220. A centrifugal separator 222 is provided below the residue tank 201. Solenoid valves are installed at the bottom of both the separation tank 104 and the residue tank 201 to control the material discharge.
[0029] Using the above scheme: After the waste solvent and extractant in the residue have been extracted for 1 to 2 hours, the solenoid valve installed on the residue tank 201 can be opened to feed it into the centrifugal separator 222. The centrifugal separator 222 separates the extract from the desolventized residue. Subsequently, the extract is sent to the existing distillation column for purification and regeneration into industrial-grade solvent for reuse. The desolventized residue after separation is vacuum-dried at low temperature to remove the extractant residue on the surface of the residue, so that the organic solvent content in the residue is ≤0.5%, eliminating flammability / volatility. The inorganic residue after desolventization, such as metal scraps and inorganic fillers in coatings, can be disposed of as general industrial solid waste, such as metal scrap recycling and inorganic filler brick making. During the feeding of solid residue, solid residue will inevitably adhere to / remain inside the separator 104 and the residue tank 201, especially in the conical section of the conical shroud. This is a common industrial phenomenon caused by gravity settling combined with conical tank slag discharge. Figure 7 and Figure 8 As shown, when the L-shaped bracket 214 passively moves, it simultaneously drives the double-headed inclined panel 216 to move, causing it to contact the corresponding two arc panels 217 during the movement. Each arc panel 217, under pressure, will cause the striking rod 218 and the T-shaped block 219 to move in opposite directions within the groove of the T-shaped T-slot plate 220. During the movement, the T-shaped block 219 compresses the spring 221, causing it to contract and deform under pressure. The installation of the spring 221 facilitates the subsequent movement of the arc panel 217 when it is not under pressure. The moving arc panel 217 automatically resets, while the two passively moving strikers 218 impact the bottom of the separator 104 and the top of the residue tank 201 respectively, causing impact vibration on both tanks. The mechanical vibration generated by the impact breaks the molecular adsorption force, viscous resistance and accumulation friction between the residue and the tank wall, allowing the attached / accumulated residue to fall off the tank wall and converge towards the slag discharge port under gravity, and be discharged with the slag discharge liquid, reducing the residue residue on the tank wall from the source and reducing the frequency of subsequent manual cleaning.
[0030] One point to add is that the residue tank 201 is made entirely of transparent material, allowing for real-time observation of the internal residue processing. The feed plug on the residue tank 201 is used to add new extract before feeding the crushed and ground solid residue, making the feeding process convenient and quick. The upper surface of the belt in the synchronous belt 203 is equipped with a protective cover to wrap the belt and prevent contact with the solution. The belt is also corrugated to prevent slippage between it and the tooling wheel, thus ensuring the coefficient of friction between the two.
