Description

Technical Field

[0001] The invention belongs to the technical field of hydrocarbon cleaning machines, and in particular relates to a hydrocarbon cleaning machine with a solvent recovery device. Background Art

[0002] Hydrocarbon cleaning machines mainly utilize the cavitation effect of ultrasound combined with the chemical decontamination effect of hydrocarbon cleaning agents to perform comprehensive cleaning under vacuum conditions. Specifically, the ultrasonic generator emits a high-frequency oscillation signal, which is converted into high-frequency mechanical oscillations through the transducer and propagated into the cleaning fluid, causing the liquid to flow and generate a large number of bubbles. These bubbles burst after reaching a certain level of air pressure, gradually removing stains on the surface of the object. At the same time, hydrocarbon cleaning agents, as cleaning solvents, have good dissolving power and decontamination ability, and can effectively remove impurities such as oil, dirt, and rust from the surface of the workpiece.

[0003] The hydrocarbon solvent recovery unit is a device specifically designed for treating waste hydrocarbon solvents. It is used to recover and purify waste organic solvents from waste gas or waste liquid to reduce environmental pollution and achieve resource reuse. The organic solvents in the waste gas or waste liquid are separated and purified through a distillation tower, and finally cooled and collected through a condenser to effectively recover and reuse the waste hydrocarbon solvents, reducing waste and environmental load.

[0004] At present, in the process of recycling and treating waste hydrocarbon solvents, hydrocarbon solvent recovery devices will produce some hydrocarbon waste residues in the vacuum distillation tank. These hydrocarbon waste residues are usually composed of impurities, pollutants and solid particles in the solvent. In order to ensure the recovery efficiency and recovery quality of the hydrocarbon solvent recovery device, the generated hydrocarbon waste residues need to be cleaned regularly. However, the existing cleaning methods are mostly manual cleaning, which is cumbersome and labor-intensive. Therefore, a hydrocarbon cleaning machine with a solvent recovery device is needed to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0031] like Figure 1-10 As shown, a hydrocarbon cleaning machine with a solvent recovery device of the present invention includes a cleaning machine body 1, a vacuum distillation tank 10 and a tank cover 11. The vacuum distillation tank 10 is installed inside the cleaning machine body 1, and the tank cover 11 is installed on the upper side of the vacuum distillation tank 10. A plurality of linearly distributed cleaning tanks 12 are provided inside the cleaning machine body 1, a recovery chamber is opened inside the cleaning machine body 1, and a plurality of recovery liquid pipes 13 matching the cleaning tanks 12 are provided inside the cleaning machine body 1. A total liquid inlet pipe 14 matching the plurality of recovery liquid pipes 13 is fixed inside the cleaning machine body 1. The total liquid inlet pipe 14 A liquid inlet pump 15 is provided on the upper side, a first telescopic tube 16 is installed between the main liquid inlet pipe 14 and the tank cover 11, a plurality of steam pipes 17 matching the recovery liquid pipe 13 are provided inside the cleaning machine body 1, a second telescopic tube 18 is provided between one end of the plurality of steam pipes 17 and the tank cover 11, and a condensing spiral tube 19 matching the recovery liquid pipe 13 is provided at the other end of each steam pipe 17. A lifting assembly matching the tank cover 11 is provided in the recovery chamber, a rotating assembly matching the vacuum distillation tank 10 is provided in the recovery chamber, and a cleaning piece matching the vacuum distillation tank 10 is provided in the recovery chamber;

[0032] The cleaning member includes a cover plate 20 that is slidably assembled in the recovery chamber, a long plate 21 that is slidably assembled in the recovery chamber, a round rod 22 that is assembled and rotated together with the long plate 21 and the cover plate 20, a first spring 23 is fixed between the long plate 21 and the cover plate 20, a cleaning disk 24 that matches the vacuum distillation tank 10 is concentrically mounted on the left side of the round rod 22, a screw 25 that matches the long plate 21 is rotatably assembled in the recovery chamber, a mobile motor 26 is installed in the recovery chamber 24, the output shaft of the mobile motor 26 is transmission-connected to the screw 25, and the long plate 21 is provided with a driving member that matches the round rod 22;

[0033] The rotating assembly includes two support columns 30 that match the vacuum distillation tank 10 fixedly provided in the recovery chamber, and rotating shafts that match the support columns 30 are fixedly provided on the front and rear sides of the vacuum distillation tank 10. A first bevel gear 32 is concentrically fixed to the rear rotating shaft. A horizontal shaft 33 is installed in the recovery chamber, and a second bevel gear 34 that meshes with the first bevel gear 32 is installed on the side wall of the horizontal shaft 33. A rotating motor 35 is installed in the recovery chamber, and the output shaft of the rotating motor 35 is drivingly connected to the horizontal shaft 33.

[0034] The lifting assembly includes a lifting plate 36 that is slidably assembled inside the recovery chamber. A plurality of connecting rods 37 that match the tank cover 11 are fixed to the lower side of the lifting plate 36. An electric telescopic rod 38 is fixed to the upper side wall of the recovery chamber. The output end of the electric telescopic rod 38 is fixedly connected to the lifting plate 36.

[0035] When the present invention is in use, the output end of the electric telescopic rod 38 is extended, and the tank cover 11 is closed on the upper side of the vacuum distillation tank 10 through the lifting plate 36 and the connecting rod 37. The liquid inlet pump 15 draws the solvent in each cleaning tank 12 into the main liquid inlet pipe 14 through the recovery liquid pipe 13, and then sends it into the vacuum distillation tank 10 through the main liquid inlet pipe 14. The vacuum distillation tank 10 heats and distills the solvent until it is vaporized. The solvent vapor enters each steam pipe 17 through the second telescopic pipe 18 on the upper side, and then enters the condensation spiral pipe 19. The side wall of the condensation spiral pipe 19 abuts against the side wall of the recovery liquid pipe 13 to perform heat exchange and condense the solvent vapor, thereby liquefying the solvent vapor into a liquid solvent, and then returning it to each cleaning tank 12. No additional condensing device is required, thereby reducing production costs.

[0036] During the use of the present invention, when it is necessary to clean the interior of the vacuum distillation tank 10, the output end of the electric telescopic rod 38 is retracted, and the upper side of the tank cover 11 is pulled by the lifting plate 36 and the connecting rod 37, so that the first telescopic tube 16 and the second telescopic tube 18 are retracted. After the tank cover 11 moves to a certain height, the output shaft of the rotating motor 35 drives the horizontal shaft 33 to rotate, and the horizontal shaft 33 synchronously drives the second bevel gear 34 to rotate, and the second bevel gear 34 drives the first bevel gear 32 to rotate, and the first bevel gear 32 drives the vacuum distillation tank 10 to rotate through the rotating shaft. After the tank 10 is rotated to a horizontal angle, the output shaft of the moving motor 26 drives the screw 25 to rotate, and the screw 25 drives the long plate 21 to move. The long plate 21 pushes the cover plate 20 to move synchronously through the first spring 23. After the cover plate 30 and the opening of the vacuum distillation tank 10 are closed, as the long plate 21 continues to move, the first spring 23 is compressed, and the driving member drives the round rod 22 to rotate. The round rod 22 synchronously drives the cleaning disk 24 to rotate, thereby cleaning the interior of the vacuum distillation tank 10, which can realize automatic cleaning, save labor costs, and improve cleaning efficiency.

[0037] The present invention drives the tank cover to move upward through the lifting component, drives the vacuum distillation tank to rotate through the rotating component, drives the screw to rotate through the moving motor, and synchronously drives the long plate to move, so that the cover plate abuts against the vacuum distillation tank, and the cleaning disk cleans the inside of the vacuum distillation tank under the drive of the driving member, thereby eliminating the need for manual operation and realizing automatic cleaning.

[0038] The driving member includes a circular shaft 40 rotatably assembled with the long plate 21, and a pulley 41 is concentrically fixed to the right side of the circular shaft 40 and the circular rod 22, and a belt 42 is installed between the two pulleys 41. A round block is concentrically fixed to the right side wall of the second bevel gear 34, and a circular groove matching the horizontal shaft 33 is opened inside the round block. A plurality of circumferentially distributed grooves 43 are opened on the side wall of the horizontal shaft 33. The second bevel gear 34 and the inner wall of the round block are fixed with a plurality of blocks matching the grooves 43. A gear ring 44 is concentrically fixed to the right side of the round block, and a gear 45 matching the gear ring 44 is concentrically fixed to the left side of the circular shaft 40. A support rod matching the horizontal shaft 33 is fixed to the side wall of the recovery chamber, and a second spring 46 is installed between the second bevel gear 34 and the support rod.

[0039] When the present invention is in normal use and needs to clean the vacuum distillation tank 10, under the elastic action of the second spring 46, the second bevel gear 34 is always engaged with the first bevel gear 32. After the vacuum distillation tank 10 is rotated to a horizontal angle, the moving motor 26 drives the long plate 21 to move through the screw 25. After the gear 45 on the side wall of the circular shaft 40 is engaged with the ring gear 44, it continues to push the ring gear 44 and the second bevel gear 34 to slide, so that the second bevel gear 34 is disengaged from the first bevel gear 32. The output shaft of the rotating motor 35 continues to drive the horizontal shaft 33 to rotate. The horizontal shaft 33 drives the second bevel gear 34 and the ring gear 44 to continue to rotate through the slot 43, thereby driving the circular shaft 40 to rotate. The circular shaft 40 drives the round rod 22 to rotate through the pulley 41 and the belt 42, so that the cleaning disk 24 cleans the inside of the vacuum distillation tank 10. Using one rotating motor 35 to simultaneously complete the rotation of the vacuum distillation tank 10 and the rotation of the cleaning disk 24 reduces the production cost and use cost of the equipment.

[0040] A vertical limiter matching the vacuum distillation tank 10 is provided in the recovery chamber. The vertical limiter includes two symmetrically distributed support platforms 50 slidably assembled on the lower side of the recovery chamber. An arc-shaped plate 51 matching the vacuum distillation tank 10 is fixed on the upper side of the support platforms 50. A through groove matching the support column 30 is opened on the upper side of the support platforms 25. A long block is fixed on the lower side of the recovery chamber. A plurality of third springs 52 are fixed between the support platforms 50 and the long block. A plurality of linearly distributed square plates 53 are slidably assembled on the front and rear side walls of the recovery chamber. An elliptical rod 54 is rotated together between the square plates 53 and the support platforms 50. A plurality of vertical rods 55 matching the square plates 53 are fixed on the lower side of the lifting plate 36.

[0041] During normal use of the present invention, the output end of the electric telescopic rod 38 is extended, and when the tank cover 11 and the vacuum distillation tank 10 are closed through the lifting plate 36 and the connecting rod 37, the lower side of the vertical rod 55 on the lower side of the lifting plate 36 pushes the square plate 53 to the lowest position. The square plate 53 minimizes the distance between the support platforms 50 on both sides through the elliptical rod 54, causing the third spring 52 to be compressed, thereby allowing the support platforms 50 on both sides and the curved plate 51 to better support and limit the vacuum distillation tank 10, ensuring normal use of the vacuum distillation tank 10;

[0042] When the present invention is in use, when the vacuum distillation tank 10 needs to be cleaned, the output end of the electric telescopic rod 38 drives the tank cover 11 to move upward through the lifting plate 36, and the lifting plate 36 simultaneously drives the vertical rod 55 to move upward. Under the elastic action of the third spring 52, the support platforms 50 on both sides are simultaneously away from the long block, thereby ensuring the normal rotation of the vacuum distillation tank 10 and the smooth use of the device;

[0043] Furthermore, both support columns 30 are provided with elliptical holes matching the rotating shaft, thereby ensuring that the support platform 50 is smoothly inserted into the lower side of the vacuum distillation tank 10 , thereby providing support for the vacuum distillation tank 10 .

[0044] An annular table 60 is fixedly provided in each of the cleaning tanks 12, and a filter plate 61 matching the annular table 60 is installed in each of the cleaning tanks 12; the solvent in the cleaning tank 12 is filtered to prevent impurities from entering the vacuum distillation tank 10, thereby ensuring the purity of the solvent entering the vacuum distillation tank 10.

[0045] A collecting box 65 is fixedly provided on the lower side of the cover plate 20 to collect the cleaned residues.

[0046] The main liquid inlet pipe 14 and the plurality of steam pipes 17 are all arranged at an angle to facilitate the movement of the solvent and steam.

[0047] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
