Definitions

  • the present invention relates to a vibration sieve device, and more particularly to a vibration sieve device that includes a chute for discharging a material screened by the vibration sieve device.
  • a sieve that includes a net having a predetermined mesh is used. That is, the mixture can be screened by putting the mixture in the sieve and by swinging or vibrating the sieve.
  • the vibration sieve device includes: a supply part configured to supply a mixture; a screen (net) disposed horizontally or slightly obliquely; a vibration part configured to vibrate the net; a discharge part configured to discharge a screened material; and an oversize material discharge part configured to discharge a material remaining on the screen.
  • a discharge chute is used in general as the oversize material discharge part configured to discharge a material remaining on the screen from the vibration sieve device.
  • the discharge chute has an inclined inner bottom surface. With the supply of a material from one end of the discharge chute onto the inner bottom surface, the material slides or rolls on the inner bottom surface so that the material can be discharged from the other end of the discharge chute.
  • Patent Document 1 JP-UM- A-7-25975
  • a material is supplied to the discharge chute by letting the material fall onto the inner bottom surface of the discharge chute from the oversize material discharge part of the vibration sieve device.
  • the material discharged from the oversize material discharge part has a certain degree of size. Accordingly, an impact generated when the material falls onto the inner bottom surface of the discharge chute is large and hence, there may be case where the inner bottom surface of the discharge chute is deformed or damaged due to the impact. When such damage occurs, the movement of the material on the inner bottom surface of the discharge chute becomes difficult. In a worst case, there is a possibility that the discharge chute is clogged with a material. Accordingly, when the inner bottom surface of the discharge chute is damaged, maintenance such as repair becomes necessary so as to maintain the movement of the material.
  • a method is considered where a wall thickness of a material used for forming the discharge chute is increased or a material property of such a material is changed.
  • a discharge chute is formed using an iron plate made of carbon steel or the like, the increase in a wall thickness of the material gives rise to drawbacks such as lowering of treatment ability or acceleration of the occurrence of cracks due to the increase in a weight of the vibration sieve device.
  • drawbacks such as lowering of treatment ability or acceleration of the occurrence of cracks due to the increase in a weight of the vibration sieve device.
  • a discharge chute is manufactured using a raw material that is light-weight and has high durability compared to an iron plate, there is a possibility that a burden on cost for the manufacture and the maintenance of the vibration sieve device becomes high. Further, it is not always the case that such a material is superior to an iron plate with respect to a repeatedly applied stress.
  • vibration generated by the vibration sieve device cannot be used for moving a material and hence, it is necessary to smoothly supply the material from the vibration sieve device to the fixed chute.
  • the material supplied to the fixed chute from the vibration sieve device must be smoothly moved on the fixed chute.
  • a method for smoothly moving the material on the fixed chute considered is a method where a difference in elevation that the material falls from the vibration sieve device to the fixed chute is increased or a method where inclination of an inner bottom surface of the fixed chute is increased or the like, for example.
  • a difference in elevation or an inclination angle is limited because of restriction imposed on the connection with a succeeding step, an installation space or the like and hence, it is not always possible to ensure a proper difference in elevation or a proper inclination angle. Further, when a difference in elevation is increased, an impact generated when the material falls on an inner bottom surface of the fixed chute is increased and hence, impact resistance is lowered even when vibration resistance is increased.
  • the present invention has been made in view of the above-mentioned circumstances, and it is an object of the present invention to provide a vibration sieve device capable of preventing the occurrence of damage to a chute while maintaining discharge of a material using the chute.

  • a vibration sieve device is the vibration sieve device according to the first, the second, the third or the fourth invention, characterized in that a layer made of ultrahigh molecular weight polyethylene is formed on the inner bottom surface of the discharge chute.
  • the case and the discharge chute are not fixed to each other, when the case, which is vibrating, is brought into contact with the discharge chute, vibration of the case can be transmitted to the discharge chute.
  • vibration of the case can be converted into a force that moves a residual material in the discharge chute and hence, the residual material can be smoothly moved in the discharge chute.
  • vibration applied to the discharge chute can be decreased and hence, the occurrence of damage to the discharge chute due to vibration can be prevented.

  • ultrahigh molecular weight polyethylene or the like can be used.
  • the layer 11p exhibits small friction and becomes slippery and hence, stagnation of a residual material MR can be easily prevented. Further, when the sheet is damaged, the sheet can be exchanged individually and hence, it is possible to acquire an advantageous effect that an operation time for maintenance or the like can be shortened.
  • the bottom plate 11 may be formed of a planar member, or may be formed of a groove-shaped member having an approximately U-shaped cross section or the like.
  • the bottom plate 11 of the discharge chute 10 may be formed of one sheet. However, from a viewpoint of enhancing rigidity of the discharge chute 10, it is desirable that the bottom plate 11 have the duplicate structure as shown in Fig. 2 and, further, a reinforcing frames 10f be formed on side walls of the discharge chute 10. With such a configuration, it is possible to increase rigidity of the discharge chute 10 per se against vibration.
