Definitions

  • the present invention relates to a cleaning nozzle used in automatic cleaning of inside of particulate material manufacturing equipment, tanks, chutes or the like in high temperature water or other fluid.
  • various cleaning nozzles of this sort have been known, for example, the cleaning nozzle for rotating a rotary element assembled in a cylinder by the fluid flow flowing in the cylinder connected to a cleaning fluid feed pipe, and injecting the cleaning fluid from an injection pipe while swiveling the injection pipe through a reduction gear train by rotation of this rotary element, the cleaning nozzle for injecting the cleaning fluid from the injection pipe while forcing to swivel the injection pipe assembled in the lower part of the cylinder, by driving motor mounted on the upper part of the cylinder, through a drive shaft penetrating through the inside of the cylinder, and the cleaning nozzle for rotatably disposing the injection pipe arranged on the circumference centered around the axial center of the cylinder, and rotating the injection pipe around the axial center of the cylinder by the reaction force of the jet flow injected from the injection pipe.
  • the mechanism is complicated or increase in size by the reduction gear train, and compressed air and electric power are required aside from the cleaning fluid.
  • the greatest demerit of the conventional cleaning nozzles is that the nozzle main body is clogged with the particulate material when treating the particulate material inside the particulate manufacturing equipment, tank or chute because it is installed in the projected state inside the particulate manufacturing equipment, tank or chute, possibly resulting in inability of rotation mechanically, inability of cleaning when cleaning, inability of stable operation of the equipment due to closure or sticking phenomenon of particulate material by the cleaning nozzle, or decrease of production capacity or lowering of product quality as the case may be.
  • each manufacturing line unit and in each machine, or also in each manufacture if necessary, it may be considered to control sequentially by programming the cleaning cycle [for example, 1. primary washing in tap water (cleaning with detergent, 2. finish washing by deionized water or distilled water, 3. drying by hot air], and cleaning conditions [for example, 1. washing pressure, 2. washing temperature, 3. washing speed, 4. hot air temperature, 5. washing time or water volume, 6. hot air drying time, etc.].
  • cleaning cycle for example, 1. primary washing in tap water (cleaning with detergent, 2. finish washing by deionized water or distilled water, 3. drying by hot air
  • cleaning conditions for example, 1. washing pressure, 2. washing temperature, 3. washing speed, 4. hot air temperature, 5. washing time or water volume, 6. hot air drying time, etc.
  • a cleaning nozzle comprises a cylinder tube in an intemal tubular form, having a piston slidably inserted inside, and a piping opening for connection of cleaning water feed pipe provided at the rear end thereof, and also having a rod cover possessing an internal stopper for defining the forward position of the piston inserted and fixed inside the front end part thereof, a hollow piston rod slidably inserted in the rod cover and integrally affixed to the piston, a pressure spring compressed and placed between the piston and rod cover, and always pulling the piston rod rearward, an injection nozzle affixed to the front end of the piston rod, and injecting cleaning water while rotating by the injection pressure of the cleaning water itself, and a poppet valve affixed to the front end of the injection nozzle, and closing flush a front end opening part of a cylindrical housing extended and mounted on the front end of the cylinder tube by the pressure spring.
  • the injec- lion nozzle is pushed out of the mounting plane by the pressure of the cleaning water, and injects the deaning water while rotating, thereby cleaning the necessary parts by the cleaning water.
  • the injection nozzle stops injecting the cleaning water, and is at the same time retracted into the housing, thereby closing the mounting part by the poppet valve.
  • numeral 1 is a cylindrical cylinder tube having a piston 2 slidably inserted inside by way of a seal member 3, and a piping opening 4 for connection of cleaning water feed pipe is screw-fitted to the rear end part (the left end part in Fig. 1), and a cylindrical housing 5 is screw-fitted to the front end part (the right end part in Fig. 2), and an expanding valve seat 5a is formed at the front end face of this housing 5.
  • Numeral 6 is a rod cover inserted and fixed inside of the front end of the cylinder tube 1, and an interval stopper 7 in a cylindrical form is integrally formed at the rear end face, and the forward position of the piston 2 is defined as the piston 2 abuts against this internal stopper 7.
  • the forward position of the piston 2 may be adjusted by varying the length of the intemal stopper 7.
  • Numeral 8 is a hollow piston rod slidably inserted in the rod cover 6 by way of a seal member 9, and the piston 2 is integrally affixed to its rear end part, and it moves back and forth together with the piston 2.
  • Numeral 10 is a pressure spring compressed and placed between the piston 2 and the rod cover 6, and it always pulls backward the piston rod 8 through the piston 2.
  • Numeral 11 is an injection nozzle mounted on the front end of the piston rod 8, and a rotary head 11b, although not shown, forming multiple slits toward the tangential direction in the outer circumferential surface is rotatably disposed on a feed pipe 11 a of the injection nozzle 11, and the cleaning water flowing into the feed pipe 11 a from the piping opening 4 through the piston rod 8 is injected from the slits in the rotary head 11 toward the tangential direction, and the nozzle 11 is rotated in the reverse direction of the injection direction of the cleaning water by the reaction of the cleaning water injected from the slits.
  • Numeral 12 is a poppet valve affixed to the front end of the injection nozzle 11 concentrically with the housing 5, and it is pulled backward by the pressure spring 10 through piston 2, piston rod 8 and injection nozzle 11 and is pressed tightly against the valve seat 5a of the housing 5 to be flush with the front end face of the housing 5, and the front end opening of the housing 5 is closed at the same time.
  • Numeral 13 is a cylindrical tube stand affixed on an outer wall 14 of particulate manufacturing equipment, tank, chute or the like so that its inner face and its front end face may be flush with the outer wall 14, and a cylindrical sleeve 15 is fused butt to butt to the rear end, and a mounting flange 15a is integrally formed at the rear end of this cylindrical sleeve 15.
  • Numeral 16 is a mounting flange affixed on the outer circumferential surface of the housing 5, and the housing 5 is inserted into the tube stand 13 and cylindrical sleeve 15 so that its front end face may be flush with the front end face of the tube stand 13, and by fitting into the mounting flange 15a of the cylindrical sleeve 15 through a clamp 17, the cylinder tube 1 and housing 5 are attached to the outer wall 14.
  • the piston 2 moves forward, resisting the pressure spring 10 by the pressure of the cleaning water, and the injection nozzle 11 and poppet valve 12 are pushed out from the front end face of the housing 5 through the piston rod 8, and the cleaning water is simultaneously passed into the injection nozzle 11 through the piston rod 8, and the injection nozzle 11 injects cleaning water while rotating.
  • the injection nozzle 11 is inserted inside of the particulate manufacturing equipment, tank, chute or the like in a stroke until the piston 2 abuts against the internal stopper 7, and the cleaning parts, that is, the inside parts of the outer wall 14 are cleaned by the cleaning water injected from the slits.
  • the injection nozzle 11 stops injection of compressed air, and the injection nozzle 11 and poppet valve 12 are retracted into the housing 5, and the front end opening part of the housing 5 is closed by the poppet valve 12. Then, the particulate manufacturing equipment, tank, chute or the like will treat the particulate material.
  • the invention is not limited to the above embodiment alone, and, for example, the poppet valve 12 and the valve seat 5a of the housing 5 may contact with a spherical surface, or by varying the length of the internal stopper 7, the stroke of the injection nozzle 11 may be adjusted, and furthermore by varying the slit shape, dimensions, number of slits and other conditions of the injection nozzle 11, the optimum cleaning condition for the object to be cleaned may be obtained.
  • the cleaning nozzle of the invention is not projecting from the inside of the equipment mounting part while not cleaning, and the equipment mounting part is completely dosed by the poppet valve, and since the inside of the equipment mounting part is flat, the movement of the particulate material is not impeded even when the particulate material is treated, and problems of contamination and others may be avoided.
  • the injection nozzle is rotated by the injection pressure of the deaning water itself when cleaning, it is possible to feed in all directions of 360 degrees.
  • the cleaning equipment may be installed in a place which is not easily accessible by the workers.
