Description

The invention relates to the technique of cleaning hollow articles and can be applied in mechanical engineering for cleaning manufactured, completed or process hoses. A washing device is known that contains a hydraulic system for pumping washing liquid, supply and discharge pipes, a pulsator providing alternating accelerations of the washing agent and deformation of its walls. 1J The elastic shell of the pipeline being washed damps the fluctuations of the liquid and the cleaning efficiency is noticeably reduced. In addition, the device is difficult to manufacture and operate. The closest to the present invention is a device containing a hydraulic system for pumping washing liquid, leading to the discharge pipelines, a device for placing the product in the form of an arcuate table with the ability to move G2. The device also does not provide high quality cleaning, as sticking to the wall of the pipeline, they are washed by a viscous laminar layer, the velocity of the liquid in which is non-absorbent and flushed away. The purpose of the invention is to increase the efficiency of cleaning flexible pipelines, simplifying the design of the installation and its operation. This goal is achieved by the fact that in a device for cleaning elastic pipelines, including a system for pumping washing fluid, supply and discharge pipes Q with adapters for connecting to an elastic pipe and means for discharging the elastic pipe, the latter is made in the form of an oval section drum, the generator of which is a helix-shaped bed with a profile corresponding to the profile of an elastic pipeline, and the drum is installed with the possibility of turning the SUBMITTING discharger pipelines relative to the elastic pipeline. FIG. 1 shows the proposed device for cleaning elastic pipes, general view; Fig 2 is a b & raban general view; in fig. 3 - the same, left view. The device contains a skeleton 1, in the rack of which the drum 2 is rotatably & amply fixed on which the washed elastic pipe 3 is wound. The supply pipe 6 and the discharge pipe 7 are connected to the hanging ends of the pipe-running water through adapters 4 and 5. Adapters 4 and 5 provide free rotation of the flushed pipeline around its axis relatively technological pipelines 6 and 7, which, in turn, are connected to stevda 8 for pumping washing liquid by fittings 9. Drum 2 is equipped with a screw-shaped bed A (see fig. 2), whose profile corresponds to the cross section of the pipeline 3. The lodgment may be formed by a profiled rubber tape 10 wound on the drum and attached to it. The drum is kinematically coupled to an 11 eix rotary drive. In the cross section of the drum (fig. 3), the minimum radius corresponds to the maximum permissible bend radius of the elastic pipe being washed. Uglanovka works as follows, Include pumping of liquid through the flushed pipeline (using stand 8). In the process of pumping, the drum 2 is rotated in mutually opposite directions with the aid of the actuator 11, ensuring the movement of the washed elastic pipeline through the drum from the beginning to the end. The number of cycles of movement (rotation) is 5–10, after which it is advisable to turn the pipeline about its axis. In the process of washing, it is desirable to change the direction of the flow of washing liquid to the opposite. Deformed sections of the pipeline contribute to a better separation of contaminants from the walls, especially corrugated pipelines. The rotation of the oval drum provides alternating accelerations of the bostovoda wound around it, which leads to shaking loose ends in the longitudinal and transverse lines. vertically hanging sections of the pipeline contributes to a better leaching of the contaminants, since in them the forces of the contaminants' weight coincide with the direction of flow movement (vertical) and the lawsuit / the secondary suspension of the contaminants in the corrugations of the pipeline. The drum has a comparatively uncomplicated construction, since the cradles for laying the hose are wound with elastic profiled tape.

Pipeline fluctuations during the flushing process are provided by a relatively simple device.

The proposed installation occupies a smaller in comparison with the known production area, since the flushable pipeline is located vertically in it.

The device is easier to operate, the process of flushing is mechanized.

The economic effect of the use of the device is due to the increase in the quality of the elastically, especially chlorinated pipelines, which reduces the cost of repairing products and increases the reliability of their eco-use. In some cases, an emergency situation can be ruled out.
