Abstract

PURPOSE:To have an arrangement in which stored objects are exhausted under precision control, by preventing effectively occurrence of the arching phenomenon in the storing container by means of rotation of the container and by controlling the falling position and revolving speed of the container with a specific precision control means. CONSTITUTION:In order to put the objects in a storing container 1, a turning device 7 is operated to turn the container 1 up and down so that the input opening 2 becomes the storing point. In order to exhaust the input objects to the downflow facilities in a certain fixed quantity, the turning device 7 is operated to turn for an angle smaller than 120 deg., and then the rotational device 10 is operated to let the container 1 rotate. The objects stored in the container 1 begin the action specifically actuated by the friction against the internal surface of the container and also by rotational motion to fall down little by little from the input opening 2. The level of exhausted objects on the shoot 11 of the downflow facilities is sensed by a level sensing device 12, and the signal obtained is sent to the drive motor 14 for the rotational device and the one 13 for the turning device, and on the basis of the signal therefrom the turning speed and rotational speed and controlled for adjustment of the attitude of the container 1.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to an improvement in a device suitable for storing and discharging a quantity of water.

Conventionally, dehydrated sludge. A mixture of sludge and cement.

As a device for temporarily storing and quantitatively supplying highly sticky substances such as a mixture of gp ash and cement.

As shown in Figures 1 and 2, Honopa casing 01
An apparatus is used in which a two-axis screw conveyor 02 is attached to the bottom of the conveyor belt. In this device, a sticky substance is introduced into a hopper casing 01 from the upper part of the hopper casing 01, and is then discharged from a lower discharge port 03 by a scree conveyor 02.

However, with such equipment, arching tends to occur within the hopper casing, and sticky substances tend to adhere to the spriller conveyor.

Therefore, smooth discharge is difficult, and in the case of cement mixtures, the residue in the hopper solidifies, causing problems in continuous use.

The present invention proposes a device capable of temporary storage and quantitative discharge that eliminates the above-mentioned drawbacks. means for inverting the storage container around a substantially horizontal transverse axis; means for rotating the storage container around a longitudinal axis;
The storage container is characterized by being equipped with a support base that supports the storage container so that it can be turned over and rotated, and a control means that controls the overturning position and rotational speed of the storage container in order to keep the amount of stored material discharged from the receiving port constant. Provides a temporary storage and discharge device.

The device of the present invention has the above configuration, and in order to put the stored material into the storage container, the container is turned over by operating the tipping device so that the receiving port is at the top.

After receiving the stored material, operate the tipping device and rotating device to overturn the storage container so that the receiving port is gradually positioned downward, and at the same time rotate the storage container to discharge the stored material from the receiving port. let

Therefore, according to the device of the present invention, since the stored material is discharged while rotating the storage container, even when handling highly adhesive substances, the arching phenomenon does not occur and smooth discharge work can be performed, and the stored material can be discharged smoothly. When discharging the stored material, the overturning position and rotational speed of the storage container are appropriately controlled while gradually discharging the stored material, resulting in extremely high precision quantitative discharging performance.

Next, a third embodiment of the device of the present invention will be explained based on the drawings.
~ In Figure 5, 1 is a storage container.

It has a receiving port 2 that also serves as a discharge port at one end, and an opening 3 at the bottom of the other end, and a lid plate 4 is attached to the opening 3 so that it can be opened and closed with one touch.

Reference numerals 5 and 6 are support stands for the storage container l, and an overturning device 7 is installed on the support stands 5 and 6, and a cylindrical body 8 surrounding the storage container 1 is fixed to the overturning device 7 via a horizontal rotation shaft 9. has been done.

Reference numeral 10 denotes a rotating device mounted on the cylindrical body 8. On the outer surface of the central cylindrical portion facing the inner surface of the cylindrical body 8 of the storage container l, there is a driven gear (not shown) for rotational movement or the same function as a gear. A chain is attached to the cylindrical body 8 over the entire circumference, and a plurality of rollers (not shown) for supporting and guiding the trench storage container 1 are in contact with the outer surface of the storage container 1.
is attached to the inside of the

Note that the rotating device 10 is fixed on the cylindrical body 8, and the relative position between the rotating device 10 and a driven gear (not shown) attached to the outer surface of the storage container 1 remains unchanged regardless of the overturning angle of the storage container 1. It is.

In such a device, in order to put the stored product into the storage container 1, the overturning device 7 is operated to overturn the storage container 1 so that the receiving opening 2 becomes the fish storage area. After receiving the stored material,
In order to discharge a fixed amount to downstream equipment, the overturning device 7 is driven once to overturn it to an angle smaller than 120°, and then the rotation device 10 is driven to rotate the storage container 1.

The stored material in the storage container 1 causes a kiln action due to rotational movement and friction on the inner surface of the storage container, and spills out little by little from the receiving port 2. As the amount spilled from the receiving port 2 gradually decreases, the overturning angle is increased to maintain quantitative discharge performance.

After all the accumulated material has been discharged, return to the tipping position.

Prepare to receive new stored material. In addition, if quantitative discharge is not required, cover plate 4 can be removed.

The entire amount may be discharged through the opening 3.

FIG. 6 shows a control means for quantitative discharge in this apparatus, in which the level of discharged substances on the sheet 11 of the downstream equipment is detected by the level detection device 12.

The detection signal is sent to the drive motor 13 of the overturning device and the drive motor 14 of the rotating device, and based on the signal, the overturning speed and rotation speed are controlled to adjust the attitude of the storage container l.

Therefore, according to this device, the arching phenomenon within the container can be effectively prevented by rotating the storage container.

In addition, since the stored material is discharged while precisely controlling the overturning position and rotational speed of the storage container by the control means, extremely high precision quantitative discharge performance is achieved.

In addition, an opening is provided at the bottom of the storage container, and the lid plate can be attached and removed in a single manner, making maintenance management such as internal cleaning easier. In addition, when a fixed amount of discharge is not required, the opening can be opened to easily dispense the entire amount. It can also be discharged.

As described above, according to the apparatus of the present invention, a good quantitative discharge function can be obtained, and it is particularly suitable for substances that are difficult to handle, such as highly adhesive substances.

As a component of cement solidification equipment for sludge, BP ash, etc.
It is suitable as a device for temporarily receiving and discharging kneaded material from a patch mixer, and as a component of a sludge mixing device, a sludge supply tank to a patch mixer, a device for temporarily receiving and discharging kneaded material from a patch mixer, etc.
