Description

Technical Field

[0001] This invention relates to the field of flash evaporator technology, and more specifically to a flash evaporator for washing solvents. Background Technology

[0002] In the industrial manufacturing and processing sector, flash tanks are common equipment. They are devices where high-pressure saturated liquids enter a relatively low-pressure container, and due to the sudden drop in pressure, these saturated liquids transform into a portion of the container's saturated vapor and saturated liquid under the container's pressure.

[0003] Flash tanks can be categorized by function into vacuum flash tanks, washing solvent flash tanks, etc., and by size into small, medium, and large flash tanks. Large flash tanks also vary significantly in height, reaching tens of meters. Large flash tanks are expensive and have a long service life. Because they are installed outdoors, their outer surfaces must undergo rust-proofing treatment. However, over time, the rust-proofing layer gradually ages and loses its effectiveness. Therefore, flash tanks installed outdoors often develop rust, especially in acid rain areas, where the rust is particularly noticeable, significantly reducing their lifespan.

[0004] To address the aforementioned issues, the current solution is to redo the rust-proofing layer. However, existing flash tanks only have vertical climbing frames for later maintenance and repair. The absence of winding climbing frames or ladders makes comprehensive rust prevention treatment of the flash tanks extremely difficult, requiring additional lifting devices. Furthermore, existing lifting devices have limited height capabilities and are unsuitable for large flash tanks. Even if flash tanks are equipped with winding climbing frames or ladders, the climbing path is long, and manual climbing with tools is extremely inefficient, resulting in difficult and time-consuming repairs. Summary of the Invention

[0005] To address the shortcomings of existing technologies and reduce climbing difficulty, improve subsequent maintenance efficiency, and lower repair costs, this invention provides a flash evaporation tank for washing solvents, comprising a tank body, a track, and an electric balancing scooter; the track is distributed spirally upwards around the outside of the tank body, the track is fixedly connected to the tank body, and the track has grooves on its upper and lower surfaces respectively;

[0006] The electric balance scooter includes a frame, a telescopic motor, and a roller assembly; the roller assembly is provided in two sets, which are connected to the track one in front of the other, and each set of roller assemblies is connected to the underside of the frame through the telescopic motor;

[0007] Both sets of roller assemblies include an upper roller, a lower roller, a roller frame, a rotary motor, and limit fasteners;

[0008] There are two upper rollers that roll in a groove on the track; there are two lower rollers that roll in a groove below the track; the two upper rollers and the two lower rollers are opposite each other, and each pair of upper and lower rollers is connected by a longitudinal crossbeam. There are four crossbeams, two of which are located on both sides of a pair of upper and lower rollers, and the other two are located on both sides of another pair of upper and lower rollers; the two crossbeams on the same side are hinged together by a hinge rod, so that the two crossbeams on the same side can swing relative to each other in the vertical plane.

[0009] Each crossbeam is hinged to the roller frame via a fixed rod. The limiting fastener is fixedly connected to the bottom of the roller frame via a connecting rod and is locked in the track to limit the swing amplitude of the roller frame relative to the crossbeam.

[0010] Each roller frame is equipped with a rotary motor. The housing of the rotary motor is fixed to the corresponding roller frame, and the rotating shaft of the rotary motor is connected to one of the upper rollers of the roller frame through a belt drive assembly. By rotating the two motors synchronously, the electric balance vehicle can move up or down along the track.

[0011] The beneficial effects of this equipment are reflected in:

[0012] 1. Using electric balance vehicles instead of manual climbing greatly reduces physical exertion, especially when carrying tools, which reduces the difficulty of maintenance, shortens the maintenance cycle, and thus reduces the labor cost of maintenance.

[0013] 2. The upper and lower rollers are engaged with the upper and lower tracks to prevent derailment and tipping. The overall structure is simple, and the electric balance vehicle has high reliability and low failure rate.

[0014] 3. Due to the spiral shape of the track, two telescopic motors are used to compensate for the height difference between the front and rear ends of the inclined track frame in order to keep the frame level. Additionally, the two fixed rods, roller frame, and hinge rod of the same roller assembly form a planar four-bar linkage. The two pairs of upper and lower rollers on the same frame will also swing as the track changes, and the hinge rod between the two crossbeams will swing to accommodate the swing amplitude between the upper and lower rollers. The swing between the upper and lower rollers will cause the roller frame to deflect. To prevent excessive deflection of the roller frame, limiting fasteners are used to limit the maximum deflection angle of the roller frame. Finally, the changes in the track are transformed into the frame swinging forward or backward within a reduced swing range.

[0015] Preferably, the cross-sectional thickness of the track is the same at any point. Since the distance between the upper roller and the corresponding lower roller is fixed, a track with a constant thickness is required to allow the roller assembly to slide back and forth.

[0016] Preferably, the upper and lower ends of each fixed rod are hinged to the roller frame and the corresponding crossbeam, respectively.

[0017] Preferably, the upper and lower bottom walls of the track are provided with two parallel grooves extending along the corresponding grooves, and the upper and lower rollers are provided with wheel bodies corresponding to the two grooves.

[0018] Preferably, the two wheel bodies of the upper roller and the two wheel bodies of the lower roller are integrated into one piece.

[0019] Preferably, the belt drive assembly includes a synchronous belt and a drive synchronous pulley, the drive synchronous pulley being coaxially fixed with the shaft of the corresponding rotary motor; the upper roller connected to the rotary motor has a driven synchronous pulley in the middle, and the synchronous belt is connected between the corresponding drive synchronous pulley and the driven synchronous pulley.

[0020] Preferably, an annular groove is provided between the two wheel bodies of the upper roller, and the driven synchronous pulley is located in the annular groove, with the two wheel bodies being integral with the corresponding driven synchronous pulley. The annular groove serves to restrict the synchronous belt, reducing the possibility of the synchronous belt slipping off.

[0021] Preferably, the outer surface of the limiting fastener is provided with a limiting groove parallel to the track, and the upper edge of the limiting groove is higher than the upper edge of the track and the lower edge of the limiting groove is lower than the lower edge of the track, thereby forming a movable gap between the limiting groove and the track. When the crossbeam swings forward or backward in the direction of travel, the frame will tilt forward or backward accordingly. To prevent the frame from tilting too much and affecting safety, the upper edge of the limiting groove contacts the upper edge of the track or the lower edge of the limiting groove contacts the lower edge of the track, thereby limiting the maximum angle of the electric balance vehicle's swing.

[0022] Preferably, the frame includes a level sensor, a button circuit board, a controller, and a power supply. The controller's input is electrically connected to the level sensor, the button circuit board, and the power supply, and its output is electrically connected to two telescopic motors and two rotary motors. The level sensor detects the angle between the frame and the horizontal plane in real time and feeds it back to the controller. The controller uses a microcontroller processor. After analyzing the angle changes, the microcontroller controls the extension and retraction of the two telescopic motors to balance the forward or backward tilt of the frame. This electric compensation method is used to maintain the balance of the electric self-balancing vehicle. The button circuit board includes function buttons for forward, backward, start / stop, and pause. Attached Figure Description

[0030] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0031] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by those skilled in the art to which this invention pertains.

[0032] like Figure 1 , Figure 2As shown, this embodiment provides a flash evaporation tank for washing solvents, including a tank body 1, a track 2, and an electric scooter 3. The track 2 is distributed spirally upwards around the outside of the tank body 1, and is fixedly connected to the tank body 1. The track 2 has grooves 4 on its upper and lower surfaces. The electric scooter 3 includes a frame 5, a telescopic motor 6, and roller assemblies. Two sets of roller assemblies are provided, one in front of the other, and are connected to the track 2. Each set of roller assemblies is connected to the lower part of the frame 5 via the telescopic motor 6. Both sets of roller assemblies include upper rollers 7, lower rollers 8, roller frames 9, a rotary motor 10, and limiting fasteners 11. There are two upper rollers 7, which roll on the grooves 4 on the track 2. There are two lower rollers 8, which roll on the grooves 4 below the track 2.

[0033] The specific connection relationships between the upper roller 7 and the lower roller 8 and the slide groove 4 are as follows:

[0034] like Figure 3 As shown, the bottom walls of both the upper and lower slide grooves 4 of the track 2 are provided with two parallel grooves 12 extending along the corresponding slide grooves 4. The upper roller 7 and the lower roller 8 are each provided with a wheel body 13 corresponding to the two grooves 12. The two wheel bodies 13 of the upper roller 7 and the two wheel bodies 13 of the lower roller 8 are integral.

[0035] like Figure 3 , Figure 4 As shown, in this embodiment, two upper rollers 7 and two lower rollers 8 are opposite each other, and each pair of upper rollers 7 and lower rollers 8 is connected by a longitudinal crossbeam 14. There are four crossbeams 14, with two located on either side of one pair of upper rollers 7 and lower rollers 8, and the other two located on either side of another pair of upper rollers 7 and lower rollers 8. The cross-sectional thickness of any point on the track 2 is the same. Since the distance between the upper roller 7 and the corresponding lower roller 8 is fixed, a track 2 with a constant thickness is required to allow for the forward and backward sliding of the roller assembly. Two crossbeams 14 located on the same side are hinged together by a hinge rod 20, allowing them to swing relative to each other in the vertical plane. Each crossbeam 14 is hinged to the roller frame 9 by a fixed rod 15, with the upper and lower ends of each fixed rod 15 hinged to the roller frame 9 and the corresponding crossbeam 14, respectively.

[0036] like Figure 2As shown, this embodiment uses a rotary motor 10 to replace manual climbing. Each roller frame 9 is equipped with a rotary motor 10. The housing of the rotary motor 10 is fixed to the corresponding roller frame 9, and the rotating shaft of the rotary motor 10 is connected to an upper roller 7 of the roller frame 9 via a belt drive assembly. By the synchronous rotation of the two motors, the electric balance vehicle 3 moves up or down along the track 2. The belt drive assembly includes a synchronous belt 16 and a drive synchronous pulley 17. The drive synchronous pulley 17 is coaxially fixed to the rotating shaft of the corresponding rotary motor 10. A driven synchronous pulley 18 is provided in the middle of the upper roller 7, which is connected to the rotary motor 10. The synchronous belt 16 is connected between the corresponding drive synchronous pulley 17 and the driven synchronous pulley 18. An annular groove 19 is provided between the two wheel bodies 13 of the upper roller 7. The driven synchronous pulley 18 is located in the annular groove 19, and the two wheel bodies 13 are integrated with the corresponding driven synchronous pulley 18. The annular groove 19 restricts the synchronous belt 16 and reduces the possibility of the synchronous belt 16 falling off.

[0037] like Figure 2 , Figure 5 As shown, the track 2 is spiral-shaped. To keep the frame 5 horizontal, the two fixed rods 15, roller frame 9, and hinge rod 20 of the same roller assembly form a planar four-bar linkage. The two pairs of upper rollers 7 and lower rollers 8 of the same frame 5 will also swing as the track 2 changes, causing these two sets of upper rollers 7 and lower rollers 8 to swing. The hinge rod 20 between the two crossbeams 14 swings to adapt to the swing amplitude between the upper rollers 7 and lower rollers 8. The swing between the upper rollers 7 and lower rollers 8 will cause the roller frame 9 to deflect. To prevent the roller frame 9 from deflecting too much, a limiting fastener 11 is used to limit the maximum deflection angle of the roller frame 9. Finally, the change of the track 2 is transformed into the frame 5 swinging forward or backward within a reduced swing range.

[0038] To limit the maximum swing amplitude of the frame 5 forward or backward, the limiting fastener 11 in this embodiment is fixedly connected to the lower part of the roller frame 9 via the connecting rod 24 and is engaged with the track 2, thereby limiting the swing amplitude of the roller frame 9 relative to the crossbeam 14. Specifically, the outer side of the limiting fastener 11 is provided with a limiting groove 21 parallel to the track 2, and the upper side of the limiting groove 21 is higher than the upper side of the track 2 and the lower side of the limiting groove 21 is lower than the lower side of the track 2, thereby forming an movable gap 22 between the limiting groove 21 and the track 2. When the crossbeam 14 swings forward or backward in the direction of travel, the frame 5 tilts forward or backward accordingly. To avoid excessive tilting of the frame 5 affecting safety, the upper side of the limiting groove 21 contacts the upper side of the track 2 or the lower side of the limiting groove 21 contacts the lower side of the track 2, thereby limiting the maximum swing angle of the electric balance vehicle 3.

[0039] To ensure smoother operation of the electric self-balancing scooter 3, a level sensor 23, a button circuit board, a controller, and a power supply are installed on the frame 5. The controller's input is electrically connected to the level sensor 23, the button circuit board, and the power supply, while its output is electrically connected to two telescopic motors 6 and two rotary motors 10. The level sensor 23 detects the angle between the frame 5 and the horizontal plane in real time and feeds it back to the controller. The controller uses a microcontroller processor, which analyzes the angle changes and controls the extension and retraction of the two telescopic motors 6 to balance the forward or backward tilt of the frame 5. This electric compensation method maintains the balance of the electric self-balancing scooter 3. The button circuit board includes function buttons for forward, backward, start / stop, and pause.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
