Abstract

The screw press (1) is directed in the direction of the discharge port and inclined upward, and the vertical axis Z forms an angle of about 45 ° to 50 ° with respect to the horizontal direction. This can provide a rather beneficial effect. The load applied in the radial direction of the bearing that rotatably supports the screw can be reduced. The length and height of the device can be reduced. A fairly high-capacity bag or container (S) can be placed below the outlet of the press. The liquid contained in the solid waste can be immediately separated by gravity from the solid waste compressed by the screw (1) and can thereby be kept hygienic.

Description

  The present invention relates to a screw press device that compresses, processes, and separates and collects solid and liquid waste mixed in an initial state discharged from, for example, a restaurant business.

  Known prior art uses a conical screw press with a pointed tip, and the screw has a smaller pitch and a smaller radius toward the discharge direction to compress the waste. Devices of this type are shown for example in DE 3429848A1, EP0239858A1, EP0790122A2 and EP1193045A1.

  All known types of screw press devices are arranged so that their axes are horizontal, require a large space when viewed from the plane, and have sufficient capacity to collect compressed waste Had to be placed at an appropriate distance from the floor in order to be placed below the outlet.

  The screw to be compressed is usually supported at the end driven by the motor so that it protrudes by a bearing, which is due to the weight of the screw when the screw is not supported by the compressed waste. At any time, receive a large force concentrated in the radial direction

  If there is a liquid in the waste to be compressed and a known type of screw press is used, for example, as shown in DE 3429848A1, a screw that is tilted at a point of about 20 ° with a sharp tip is used. However, it is difficult to separate the liquid from the compressed waste by gravity.

Problems to be Solved by the Invention

  The present invention solves these and other disadvantages in the prior art with the following idea to solve.

Means to Solve the Invention

  The screw press is tilted upward together with its discharge port, and its vertical axis is tilted at 10 ° to 80 °, preferably 20 ° or more, for example, 45 ° to 50 ° with respect to the horizontal direction. With this simple solution, the following beneficial effects can be obtained. The screw press occupies a shorter length than the space actually required when viewed from the plane. Since the press outlet will be located at a considerable distance from the floor, the height of the device can also be lower than the known device height. The press is actually placed at a short distance from the floor where the motor is located, so the outlet is a large capacity container for collecting compressed waste at a distance from the floor. It can be provided where it is sufficient to be placed below. The liquid contained in the waste remains at the initial part of the screw due to gravity because it is tilted considerably. In the initial part of the screw, it is easy to provide an opening for discharging and removing the liquid only by the effect of gravity. The liquid is placed in a storage container located below and discharged directly or by a pump into a container with high storage capacity located in the sewage system or on the side of the container storing the compressed waste. Removed. Another beneficial effect is obtained by improving the operating state of the bearing that supports the screw in a protruding state, the weight of the screw being distributed by the shaft component and less radial load, Take on.

  These and other features of the present invention and the benefits derived therefrom are better illustrated by the following description with reference to the two accompanying drawings.

  In FIG. 1, numeral 1 indicates a screw press having a pointed conical shape with a pitch decreasing in the discharge direction. The screw press is rotatably supported by a support member 102 via a bearing 3 disposed at the end. At the end, the screw is rotated by a gear motor 4 attached to the support member 102. The screw, which is rotatably mounted in the initial part, has a larger diameter at the bottom of the hopper 2 and rotates inside the housing 5 attached to the hopper from the side. Mounted on the screw is a discharge port 6 that laterally supports a collar 7 formed of copper or other material suitable for joint operation at the end of the screw. The discharge port 6 supports, at its end, a door 8 that rotates around a strut 108 traversing above and moves in the opposite direction to the elastic adjustment means 9. The elastic adjusting means 9 constitutes a closing means for bringing it into a closed position, and prevents waste from being discharged from the discharge port. Can be compressed. The housing in which the screw rotates has a longitudinal groove 100 that protrudes and / or is recessed, and the groove 100 moves the waste compressed by the recoil to the outlet 6.

  A relief portion 106 having a front arc shape that functions as a dropping member is disposed outside the lower portion of the discharge port 6. The relief 106 is fixed with a tub 206 that is supported by the horizontal frame 10 (see the drawing) and accurately guides the waste discharged from the discharge port to the collection bag S disposed below. A known type of chamber 11 is disposed above the hopper 2, and a side door 111 that is opened / closed automatically, semi-automatically, and manually is disposed in the chamber 11. The side doors 111 adjust corresponding window openings that can guide the waste that is compressed into a shape by a screw press and discharged into the collection bag S to the hopper.

  As described above, the apparatus of the present invention is characterized in that the press is tilted upward together with the discharge port 6, and the vertical axis Z is tilted by an angle A with respect to the horizontal direction. The angle A is 10 ° to 80 °, preferably 20 ° or more, for example 45 ° to 50 °. From this condition, the important beneficial effects shown in the introductory part can be achieved. The beneficial effect is that the radial load of the bearing 3 can be reduced, the length and height of the device can be reduced, and that the appropriate height is provided below the discharge outlet of the press. It is possible to arrange a bag S that can hold a volume, in particular from the solid waste that has been compressed by operating the screw 1 only by gravity (which could not be obtained previously). While being able to isolate | separate a liquid instantly, the connection part with the inside of the chamber 11 and the hopper 2 can also be kept hygienic. In order to separate, the screw 1 is provided with a disk 101 provided with holes and grooves (not shown) in the peripheral direction in the initial portion, and the disk is placed in a discharge path 12 provided at the bottom of the hopper 2. On the other hand, it is disposed at a position having an appropriate gap for discharging the liquid and is also partially engaged with the support member 102. In the embodiment shown in FIG. 1, the discharge from the discharge channel 12 is regulated by a suitable type of shut-off valve 13, and whenever open, a large volume flat where the liquid is placed below by gravity. Is released into a fresh container. In the embodiment shown in FIG. 2, the outlet of the discharge channel 12 is connected to a U-shaped conduit 15, which is arranged on the side of the collection bag S at the end. The compressed waste is discharged into a large capacity container 14 '. In the lower middle part of the conduit, a motor pump 16 is arranged for flowing liquid into the container. For example, a capacity type sensor 17 is disposed at a high portion of the conduit from the discharge path 12 to the pump 16, and the sensor 17 starts the pump when it detects that liquid has accumulated inside the conduit 15. The pump 16 may be directly connected to the discharge path of the discharge path 12, and the sensor 17 may be disposed between the pump along the conduit 15 and the collection container 14 '. If the device is arranged in a position where a discharge channel connected to the sewage system is available, the liquid to be discharged is naturally discharged directly into the discharge channel by the pressure generated by the pump 16, so that the liquid container 14 , 14 'can be removed.

  More preferably, the back S and the containers 14 and 14 ′ can be arranged in a space in the apparatus provided with a door, and are provided with a drawing device that can be pulled out from the side of the apparatus. By providing a drawer, these signals can be removed whenever an appropriate known sensor (not shown) detects that a signal is full or needs to be manipulated, Can be exchanged. According to another solution shown schematically in the drawing, the bag S and the containers 14, 14 'become very heavy when full, so that the bag S is placed on a transport structure 18 that facilitates loading and unloading into the apparatus. In addition, the containers 14 and 14 'can be arranged to facilitate transportation, and the apparatus can be operated continuously in the case of replacement by a spare carrier that carries new bags and containers. Safety means are provided for operating the apparatus so that the loading platform 18 is accurately carried into the apparatus. Connected to the loading platform 18 is an upper portion 19 of the canopy of the device arranged in front of the discharge port of the screw press. The top 19 of the canopy can be removed for easy maintenance of the compression parts 8,9.
