Description

Technical Field

[0001] The utility model mainly relates to the technical field of solvent recovery machines, and in particular to a solvent recovery machine. Background Art

[0002] The solvent recovery machine uses the principle of distillation: the solvent is evaporated by heating and becomes gaseous, and the vapor enters the cooling system and liquefies and flows out, so that clean organic solvents are recovered, thereby regenerating waste, dirty, and old organic solvents for recycling. The solvent waste generated during the processing of paints, coatings and other materials will be recycled using the solvent recovery machine.

[0003] For example, Chinese patent publication number CN219983916U discloses a solvent recovery machine, including a solvent recovery machine body, a pretreatment tank is fixedly connected to the top of the solvent recovery machine body, a mounting box is fixedly connected to the bottom of the solvent recovery machine body, a treatment tank is fixedly connected to the inside of the solvent recovery machine body, two groups of heating pipes are fixedly connected to the inner wall of the treatment tank, a condensation box is fixedly connected to the outer wall of one side of the solvent recovery machine body, a collecting pipe is fixedly connected to the inside of the condensation box, a condensation pipe is wound around the outer wall of the collecting pipe, a heat sink is fixedly connected to the outer wall of the condensation box, and a heat dissipation fan is fixedly connected to the inside of the heat dissipation box.

[0004] The above application can condense the evaporated solution inside the collection tube through a condensation box, so that the solution is condensed and discharged, and then the heat fan is used to dissipate heat and cool the inside of the condensation box, thereby improving the efficiency of condensing the evaporated solution and avoiding the situation that the evaporated solution cannot be condensed and discharged normally. However, the solvent recovery machines in the prior art all use double-layer stainless steel barrels as the main body of the distillation barrel to heat and distill the dirty and old solvents and then cool them to obtain clean solvents; there is no lifting and stirring device in the distillation barrel. For the dirty and old solvents containing solid and semi-solid materials with high viscosity such as resins, powders, and glues, the steam volatilization rate is slow, which will lead to too long distillation time and high difficulty in cleaning the residue, resulting in low overall recovery efficiency of the machine and fatigue of the operator.

[0031] The stirring and cleaning mechanism 6 comprises a rotating shaft 61 fixed on the output end of the rotating lifting mechanism 5, two mounting rings 62 are concentrically arranged on the outer side of the rotating shaft 61, a plurality of cleaning rollers 65 are arranged equidistantly between the two mounting rings 62, and a connecting column 66 is fixedly arranged at the upper and lower ends of the cleaning roller 65, and the connecting column 66 is rotatably mounted on the mounting ring 62. A connecting ring 67 is fixedly installed at the upper and lower ends of the rotating shaft 61, a plurality of cleaning blocks 68 are equidistantly arranged between the connecting ring 67 and the mounting ring 62, a T-shaped connecting ear 69 is arranged at both ends of the cleaning block 68, and a T-shaped slot connected to the connecting ear 69 is provided on the connecting ring 67 and the mounting ring 62. A supporting ring 63 is fixedly installed on the rotating shaft 61, and a plurality of stirring rods 64 are equidistantly installed on the supporting ring 63, and the stirring rods 64 are arranged obliquely, and one end of the stirring rod 64 is fixed on the supporting ring 63, and the other end is fixed on the mounting ring 62.

[0032] The rotary lifting mechanism 5 includes a driven synchronous pulley 51 rotatably mounted on the barrel cover 3, a spline shaft 55 is slidably mounted up and down at the center of the driven synchronous pulley 51, the lower end of the spline shaft 55 is connected to the rotating shaft 61, and the upper end thereof is rotatably connected to a connecting plate 56, the connecting plate 56 is fixedly connected to an electric push rod 57, and the electric push rod 57 is fixed to the mounting platform 4. A motor 54 is fixedly mounted on the mounting platform 4, and a driving synchronous pulley 52 is fixedly mounted on the output end of the motor 54, and the driving synchronous pulley 52 is connected to the driven synchronous pulley 51 through a synchronous belt 53.

[0033] Working principle:

[0034] The solvent to be recovered is placed in the distillation barrel 2. During the heating process of the distillation barrel 2, the motor 54 is started. The motor 54 drives the driven synchronous pulley 51 to rotate through the active synchronous pulley 52 and the synchronous belt 53. The driven synchronous pulley 51 drives the spline shaft 55 to rotate. The spline shaft 55 drives the rotating shaft 61 to rotate, thereby driving the stirring and cleaning mechanism 6 to rotate.

[0035] The thrust of the electric push rod 57 acts on the connecting plate 56 and pushes the rotating shaft 61 to slide up and down through the spline shaft 55, thereby realizing the lifting movement of the stirring and cleaning mechanism 6.

[0036] As the rotating shaft 61 rotates, the support ring 63 on the rotating shaft 61 drives the stirring rod 64 to rotate, stirring the solvent during the distillation process, thereby stirring the solvent, accelerating the evaporation and mixing of the solvent, and allowing the solvent to be heated more evenly, thereby improving the recovery efficiency. After the recovery is completed, the support ring 63 and the stirring rod 64 can also support and fix the mounting ring 62. During the rotation of the mounting ring 62, the cleaning roller 65 contacts the side of the distillation barrel 2. During the friction with the side of the distillation barrel 2 and under the action of the connecting column 66, the cleaning roller 65 rotates and cleans the side of the distillation barrel 2. The stirring and cleaning mechanism 6 is driven to rise and fall by the rotating lifting mechanism 5, and the side of the distillation barrel 2 is fully cleaned. When the stirring and cleaning mechanism 6 reaches the uppermost and lowermost ends, the cleaning block 68 also cleans the top and bottom of the distillation barrel 2 respectively during the rotation process, thereby removing the residual substances in the distillation barrel 2 and keeping the distillation barrel 2 clean, thereby reducing the influence of dirt and impurities on the recovery effect.

Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
