(Field of Industrial Application) This invention relates to a tube inner surface cleaning device that is directly connected to a saw cutting line and cleans the inner surface of a tube on-line. (Prior Art) As conventional pipe inner surface cleaning devices, there are, for example, those shown in (1) to (4) below. (1) Batch type immersion cleaning equipment This device stores a solvent in a cleaning tank and immerses the object to be cleaned in the solvent to perform batch cleaning. (2) Batch-type immersion steam cleaning equipment This is a batch method that performs steam cleaning in addition to the above-mentioned immersion. Solvent vapor is condensed on the surface of the object to be cleaned, and the condensate dissolves oils and fats and washes them away. , which is dried after draining. (3) Continuous cleaning device This is a device that continuously cleans one or many objects to be cleaned, and processes in the order of immersion, steam, draining, and drying. (4) Pipe inner surface treatment device using blasting This device treats the inner surface of a tube by sucking air and abrasive into the tube by adjusting negative pressure. (Problem that this invention attempts to solve) However, among these conventional cleaning devices, in the case of the batch method shown in (1) and (2), cleaning is performed offline, which reduces the number of man-hours for transportation and cleaning. There were problems in that it took a lot of man-hours and also caused scratches during handling during transportation. Furthermore, there was a problem in that chips on the inner surface of the tube accumulated in the tank, making it necessary to replace the liquid to remove the chips before the liquid deteriorated. Next, in the case of continuous cleaning shown in (3), due to the mechanism of material transport and cleaning capacity, the processing capacity is a maximum of 150 pieces/hour for short pipes and 20 pieces/hour for long pipes, and eventually However, there were problems in that the processing capacity was low and it was difficult to dispose of chips. In particular, in the case of pipes with large lengths and inner diameters, there was a problem that the draining and drying processes were poor. Finally, in the case of tube inner surface treatment by blasting as shown in (4), online processing is possible and is effective in improving the roughness of the tube inner surface, but it cannot achieve the desired effect in cleaning the tube inner surface. There was a problem that there was no. (Means for Solving the Problems) This invention was made in view of these conventional problems, and it can greatly improve the cleaning processing capacity and reliably collect chips. The purpose of the present invention is to provide a tube inner surface cleaning device that can clean the inside of a tube. To achieve this purpose, this invention includes a liquid supply section that heats a solvent liquid and supplies it to the inner surface of the tube of the workpiece, and a liquid supply section that clamps and seals the workpiece and is movable according to the length of the workpiece. a workpiece handling section, a suction section that sucks the liquid through the inner surface of the pipe of the workpiece, a liquid recovery section that collects the sucked waste liquid, and an exhaust gas recovery section that exhausts the mist-like waste liquid below a permissible concentration. and a distillation regeneration unit that cleans the waste liquid and returns it to the liquid supply unit. (Function) In this invention, an organic solvent is used as the cleaning liquid, and this is passed through the inner surface of the workpiece tube using a suction method to process it online.
The cleaning processing capacity can be greatly improved, and the inner surface of the tube can be reliably cleaned. Also,
Chips remaining on the inner surface of the tube can be reliably collected. (Example) Hereinafter, an example of this invention will be described based on the drawings. 1 to 4 are diagrams showing an embodiment of this invention. First, to explain the configuration, in Figure 1, 1
is a liquid tank (liquid supply part), and this liquid tank 1
An organic solvent (hereinafter simply referred to as liquid) 2, such as perchlorethylene, is stored inside. The liquid 2 is supplied to the inner surface of a pipe 3 (hereinafter referred to as a workpiece), which is an object to be cleaned, via a valve 4, and the amount of the liquid is regulated by the opening time and degree of opening of the valve 4. A heater 5 is provided in the liquid tank 1.
By heating the liquid 2 to a temperature below its boiling point, the liquid 2 remaining in the workpiece 3 is accelerated to vaporize, thereby shortening the cleaning time. Both ends of the workpiece 3 are clamped and sealed by seals 6 and 7 to prevent the liquid 2 from leaking outside and contaminating the environment.
The seal portions 6 and 7 are formed in a V-shape, and have a sufficient sealing effect with a simple structure. 8 is a vacuum pump as a suction part, and when the valve 4 is opened after confirming that the vacuum pressure is generated by the gauge 9, a certain amount of liquid is applied to the inner surface of the tube of the workpiece 3 by the suction force of the vacuum pump 8. Pass. As a result, the inner surface of the tube of the workpiece 3 is cleaned. The liquid 2 that has passed through the inner surface of the pipe of the workpiece 3 is generated during saw cutting, and is sucked into a collection tank (liquid collection section) 10 together with chips remaining on the inner surface of the pipe, and the chips are collected by a strainer 11 for collecting chips. be done. After supplying a certain amount of liquid, the valve 4 is closed, the other valve 12 is opened, and the liquid 2 remaining on the inner surface of the tube is removed by air blowing by introducing the atmosphere 13. The sucked liquid 2 falls into the recovery tank 10, but the mist-like perclean is sent from the exhaust side of the vacuum pump 8 to the waste gas recovery section 14, as shown in FIG. The sent percrene is adsorbed by activated carbon in the waste gas recovery section 14 so that its concentration is below a permissible level, and is exhausted outdoors as waste gas. In addition, since the liquid 2 used for cleaning has increased oil content, the distillation regeneration section 15 is used to clean it.
The liquid is purified in the distillation regeneration unit 15 and then returned to the liquid supply unit 1 as a new liquid via the intermediate tank 16 (see FIG. 2). Next, based on FIG. 3 and FIG.
7 will be explained in detail. In FIG. 3, numeral 3 is the workpiece, and both ends thereof have seal portions 6 and 7 having nozzles 18 and 19.
It is sealed with. Here, seal part 7 on the liquid suction side
is movable according to the length of the workpiece 3. That is, the workpiece 3 is moved to V by the transfer device 20.
It is supplied onto the roll 21 (see Fig. 4), and after being supplied, the cylinder 22 is activated and the entire V-roll 21 is raised by the lifter 23 (see arrow A), thereby separating the center of the workpiece 3 and the nozzles 18, 19. The centers of the two will coincide with each other. Here, work 3
If the length of the V-roll 21 is changed, there is a risk that the V-roll 21 and the seal portion 7 on the liquid suction side may interfere with each other.
(see arrow B). Next, the action will be explained. Experimental data for cleaning 10 workpieces 3 (12φ x 8.5φ) at the same time is shown in the attached table. In addition, the attached table shows the workpiece, liquid volume per die, cleaning time (total time of liquid supply + air blow), and liquid temperature, respectively. According to the cleaning results obtained from the experiment, the amount of residual oil before cleaning was 770 to 780 mg/m 2 , but after cleaning, the amount of residual oil was significantly reduced to 5 to 13 mg/m 2 . When 10 workpieces 3 of 12φ x 3000mm were processed at the same time in a 42 second cleaning cycle, 857 pieces per hour were processed.
I was able to clean and process the book. In this way, this apparatus can significantly increase the cleaning processing capacity of the workpiece 3. Note that in this experimental example, 10 lines were processed at the same time, but the process is not limited to this, and it is also possible to process 20 or 30 lines at the same time. Further, in the conventional example, the inner surface of a workpiece having a long length and a large inner diameter could not be cleaned satisfactorily, but this problem can be solved in this embodiment. Moreover, chips remaining on the inner surface of the tube can be reliably collected and can be prevented from being mixed into the liquid. Furthermore, since cleaning is performed by suction, both ends of the workpiece 3 can be sealed with a simple configuration, and leakage of liquid to the outside can be prevented. Furthermore, cleaning time can be shortened by heating the liquid, and there is no need for transportation, and no scratches occur during transportation or handling.
