Description

The invention relates to installations for applying filtering material to drainage pipes and can be used in the field of land improvement. A device d is known, pipe wrappers are filtered by a material, containing mechanisms for moving the pipe and applying filtering material to it, profile prikatochnye rollers, winding faceplate, and a mechanism for automatically controlling the degree of tension of the belt ij. The disadvantage of the device is its complexity, caused by the necessity of fixing the filter material on the pipe by winding it. Closest to the invention is a plant for the manufacture of plastic drainage pipe filters, holding a bunker, equipped with a rack and pinion valve to control the thickness of the peat layer carried by the belt conveyor, which simultaneously serves as the movable bottom of the bunker, a polystyrene tape drum that is a wrapping material for a peat filtering layer; a drum with uninsulated plastic drainage. a pipe and rollers with a pipe, rollers, a filtering layer of peat compacted on a tape, forming a cone, which ensures that the drainage pipe is wrapped with a filtering material along its perimeter, fur-. the bottom of the winding fixing the filtering material with a tape on the drain pipe, a pull mechanism pulling the tube forming a cone, a drum for receiving insulated pipes and drive mechanisms 2. A disadvantage of the known devices is the poor quality of the applied insulation due to uneven distribution of the filter material around the perimeter of the drainage pipe. The aim of the invention is to improve the quality of the applied insulation. This goal is achieved by the fact that the installation for applying filtering fiber material to a plastic drain pipe consisting of a hopper with filter material of conveyors, pipe guiding rollers, a pull mechanism and drums is provided with an additional hopper with a hollow screw installed in it, the conical part of which located in a sealing cone with a removable glass mounted on its output cone, on the outer surface of which a mesh plastic stocking is stretched, and a trailing mechanism is installed Dr. hopper with a hollow screw. FIG. 1 shows the installation, general view; in fig. 2 shows section A-A in FIG. one; FIG. 3 is a section bb of FIG. 2; in fig. 4 shows a section B-B in FIG. 3; in fig. 5 — node 1 in FIG. 3. A plant for applying filtering fiber material to a plastic drain pipe contains a drum 1 rotating on a vertical axis with a drain pipe 2, vertical 3 and horizontal 4 pipe guiding rollers mounted in pairs at the ends of the frame 5, a traction mechanism 6 and its drive 7. Following the traction mechanism on the frame 5 there is a feeder with a forming mechanism consisting of a hopper 8 with filtering material with a movable bottom 9, an inclined needle conveyor 10, an eccentric ridge 11 dz of removal of excess material A needle conveyor 12 for removing material and a guide chute 13. The forming mechanism includes a hopper 14, a hollow screw 15 installed therein with an opening for passing a drainage pipe inside it, a screw drive 16 and a sealing cone 17 with internal longitudinal slots 18. At the output end of the sealing cone 17 a removable cup 19 is installed, on the outer cylindrical surface of which the warm plastic mesh stocking 20 is heated, the conical part of the cup 19 is mounted inwards towards the outlet part of the sealing cone 17 s. with a dye. necessary for the passage of the mesh plastic stocking. The receiving drum 21 has a drive 22 with a friction clutch 23. The installation works as follows. The filter material from the hopper 8 is supplied by a movable bottom 9 to the inclined needle conveyor 10.. The latter is filled with a fibrous material and lifts it to the forming mechanism. The excess material is removed by the eccentric ridge 11. The conveyor is unloaded using a needle conveyor 12 and a guide tray 13. Before starting the entire installation, the plastic drain pipe coil is fed into the drum 1, the end of the pipe 2 passes between the vertical 3 and the horizontal 4 pipe guides using rollers and with the drive traction mechanism 6, it is pushed through the hollow auger 15. A mesh plastic stocking 20, length 20, is strung onto the outer surface of the removable cup 19 which is commensurate with the length of the drainage pipe in the bay. The end of the stocking 20 goes to the pipe 2, is fixed

on it and is passed inside the glass 19.

In the course of the installation operation, the fibrous material withdrawn by the feeder is captured by the screw 15 from the hopper 14, compacted and along the longitudinal grooves 18 of the sealing cone 17 is evenly distributed around the perimeter of the drainage pipe 2. The compacted material is caught by the corrugations moving The drainage pipe 2 and the cells of the plastic stocking 20 are pulled through the cup 19 to help maintain the shape of the insulating layer and stabilize the position of the plastic stocking. Upon exiting the cup 19, the compressed filter material is pa; the plastic plastic stocking 20 expands and stretches. Drainage pipe 2, insulated with fibrous filtering material, evenly distributed around its perimeter and held on it by a tensioned plastic mesh stocking, as well as corrugated drainage pipe,

comes through the vertical 3 and horizontal 4 pipe guiding rollers to the receiving drum 21. The actuator 22 of the receiving drum 21 has a friction clutch 23, which serves to change the angular velocity of rotation of the drum as the diameter of the coil of the insulated drain pipe increases.

Introduction to the installation for applying a filtering fiber material to a plastic drain pipe of a hollow screw installed in a bunker, placing its conical part inside a sealing cone, at the outlet of which is placed a glass with mesh plastic stockings on its outer surface, as well as placing a pulling mechanism in front of the bunker with a hollow screw allows the filtering material to be evenly distributed around the perimeter of the drainage pipe and thereby improve the quality of the applied insulation. The latter leads to an increase in the service life of drainage to silting by 1.5–2 times.
