Description

  The present invention relates to a volume reducing device for heat and cold waste materials that can clear the dimensional and weight constraints and has the ability to reduce the volume of heat and cold waste materials containing asbestos into a predetermined shape.

  Regarding the volume reduction treatment of heat insulation and cooling waste materials containing asbestos or heat preservation and cold waste materials not containing asbestos, intermediate treatment at another location away from the demolition and removal site is acceptable from the viewpoint of the harmfulness of this heat insulation and cold waste material to the human body. It has not been.

  In addition, when loading or unloading a volume reduction device for asbestos-containing thermal insulation waste material or non-asbestos-containing thermal insulation waste material, for example, when loading or unloading it to the site of demolition and removal of buildings, etc., this volume reduction device is loaded on an industrial elevator. However, at this time, the maximum height of the volume reduction device is 2 m or less, the weight is 2 tons or less, and there is a restriction that it must be movable by a caster or a carriage.

  This type of volume reduction device includes a conventional volume reduction device that compresses heat insulation and cold waste in the vertical direction using a hydraulic cylinder drive system, and a volume reduction device that compresses heat insulation and cold waste material in a horizontal direction using a hydraulic cylinder drive method. It has been known.

  However, in the case of a volume reduction device configured to compress in the vertical direction, the hydraulic cylinder is arranged vertically in the upper part of the casing constituting the compression part of the heat insulation and cooling waste material, so that the restriction in the height direction is cleared. I can't do that.

  Further, in the case of a volume reduction device configured to compress in the horizontal direction, the hydraulic cylinder is arranged in the horizontal and horizontal direction of the casing that constitutes the compressed portion of the heat insulation and cooling waste material, so that the protruding portion of the hydraulic cylinder is an industrial elevator. When it hits the inner wall of the door or the inner wall of the door, it will not be possible to clear the horizontal dimension constraint.

Next, as the performance required for this type of volume reduction device, as shown in FIG. 8, in order to reduce the thickness of the heat insulation waste material to 1/2, the compression force of 8 kg / cm ² , 1/3 In order to achieve this, a compressive force of 21 kg / cm ² is required, and in order to achieve a quarter, a compressive force of 36 kg / cm ² is required. At this time, if the flat area of the compression chamber is set to 650 mm × 450 mm in accordance with the standard dimensions of the heat and insulation waste material, the required pressing force is 23 tons in order to reduce the thickness of the heat and insulation waste material to 1/2. In order to obtain 1/3, 61 tons, and to 1/4, 106 tons. In the case of the above-described conventional volume reducing device for asbestos-containing heat insulation and cooling waste, in order to achieve such a high pressing force, the large volume reducing device is disassembled into a state that can satisfy structural constraints such as dimensions and weight. After the volume reduction work is completed, the volume reduction device must be disassembled and removed, and the volume reduction device must be disassembled and removed. It took a lot of labor to carry in and out.

Further, examples of the pressing force of the ball screw pressure pressing means 20 against the heat insulation and waste material 60 include 40 tons (20 tons × 2). At this time, since the area of the pressing surface 21a of one pressing body 21 is set to 332 mm × 468 mm, the compressive force that can be applied to the heat and cold waste material 60 is 12.9 kg / cm ² . This corresponds to a compressive force that can reduce the thickness of the heat insulation waste material to 2/5.

  The effect of the volume reduction apparatus 1 of the heat insulation and cooling waste material 60 containing asbestos or the like according to the present embodiment described above will be described below.

  In the volume reduction device 1 for the heat insulation and cooling waste material 60 according to this embodiment, first, the asbestos-containing heat insulation and cooling waste material 60 or the asbestos-free heat insulation and cooling waste material is introduced into the pressurizing chamber 11 in the main casing 3 from the inlet 12. 60 is input.

Rotation drive is performed, each pressurizing member 21 is lowered by the rotation of the ball screw 22, and a compressive force is individually applied to the heat insulation and cold waste material 60, and the heat insulation and cold waste material 60 is individually compressed and reduced in volume.

  Of course, the drive motors 32 can be synchronously rotated to simultaneously compress and reduce the volume by applying a compressive force to the heat insulation and cooling waste 60 by the two rows of pressurizing bodies 21.

  FIG. 7 shows the form of the heat insulation and cooling waste material 60 before volume reduction and after volume reduction.

  In the case of the volume reduction device 1 for the heat and cold waste material 60 according to the present embodiment, the bulk volume of the heat and cold waste material 60 is reduced after the volume reduction by one compression and volume reduction operation with respect to the heat and cold waste material 60.

  Thus, according to the volume reduction device 1 of the heat insulation and cooling waste material 60 according to the present embodiment, the required dimensional and weight restrictions can be cleared, and there is no inconvenience in carrying in and taking out the building to the demolition removal site. In addition, it is possible to realize the performance of reducing the volume of the heat and cold waste 60 into a predetermined shape.

  Further, when the above-mentioned heat insulation and cooling waste material 60 is compressed and reduced in volume, the exhaust means 51 with the dust collection mechanism is operated to suck and exhaust the dust generated in the main casing 3, thereby bringing the pressure chamber 11 into a negative pressure. By doing so, leakage of harmful dust to the outside of the apparatus can be prevented, and contamination of the work environment can be avoided.

  Next, the discharge port 13 is opened, and the discharge pusher mechanism 41 is operated, so that the heat insulation waste 60 compressed and reduced in the pressurizing chamber 11 by the discharge pusher 44 is moved outward from the discharge port 13. Extrude and move to the subsequent process.

  As a result, the compressed and volume-retained thermal insulation waste material 60 can be automatically discharged out of the apparatus and transferred to the next step.

  Further, if the hermetic sealing member 59 is disposed on the outer periphery of each of the ball screws 22 and their associated elements as shown in FIG. 5 described above, the dust etc. of each of the ball screws 22 and their associated elements, etc. There is an advantage that it is possible to prevent wear due to rusting and prevent rusting due to washing and washing in the main casing 3 after work.

  In the volume reduction device 1 for the heat insulation and cooling waste material 60 according to the present embodiment, hooks (not shown) can be attached to the lower casing 2, the main casing 3, the discharge pusher casing 4 and the like, and can be suspended by a unic or crane. It is also possible to adopt the configuration as follows.

  Further, in the volume reduction device 1 for the heat and cold waste material 60 according to the present embodiment, the pressurizing body 21, the ball screw 22, and the ball screw rotation drive mechanism portion 31 constituting the ball screw pressurizing press means 20 are arranged in two rows. However, the present invention is not limited to this, and a three-row arrangement, a four-row arrangement, or the like is also possible.

  The present invention is widely applicable as a compression press apparatus that is limited in terms of dimensions and weight and that requires a large compressive force to be compressed.
