The present invention relates to a device for separating and removing contaminants and sand contained in sewage, wastewater, and manure, and in particular, automatic discharge of centrifugal separation and sediment having a screw press installed in a cyclone separator, and proper pipe installation between each treatment device. By the present invention relates to an apparatus for automatically processing a fines, which can be effectively separated and degreased.

In general, manure is purified in a purification plant and discharged into the stream. Various manures (dirt) are contained in the manure, and these must be separated by appropriate methods. These contaminants or soils include sediment, such as sand, which are relatively heavy, and floating soils such as residues of various fruits and residues discharged from restaurants. These should be removed by appropriate means.

In order to remove these floats or deposits, it is common by screen and centrifugal dehydration.

This screen system is provided with an inlet, a waste sorting plate, a simple circular screen, and a separation between the screens. The waste is introduced from the waste inlet and sorted into the respective sizes on the sorting plate, and then small particles of contaminants and waste water are separated by the rotation of the screen. Only waste is transported into the dehydrator through the separation to allow dehydration.

Conventionally, the automatic processing device for contaminants including manure having such a structure attempts to separate the filth and the filth by a circular screen which rotates, and thus the filthy and the separated filth are transported between the separations installed on the upper side. There was a disadvantage of poor separation efficiency, that is, work efficiency.

In addition, there is a problem in that separation between the separation and separation that cannot be separated on the screen, due to the large amount of transfer, has a problem that the original function cannot be performed between the separation.

In addition, the conventional apparatus for automatically processing a contaminant requires several devices for each process. For example, several devices are needed, such as a debris treatment device including a dehydration device, a sediment handler, a float treatment device for separating floating contaminants, a cyclone device using a centrifugal action, and a plurality of storage tanks using a sedimentation effect.

Therefore, there is a problem in that the purification cost is high and wastes manpower because it goes through several processes by various devices.

In general, a cyclone separator (cyclone dust collector) uses centrifugal force to move solid particles suspended in the swirling air in the direction of the wall by the action of centrifugal force. Finally, the cyclone separator collides with the cyclone wall and is separated from the liquid airflow. It refers to a device using the cyclone principle that is collected at the bottom and discharged continuously or intermittently by mechanical means.

The cyclone separator is used for pretreatment and purification of various dust removal devices and industrial waste.

Conventional cyclone separators are applied to suspended sewage treatment plants for treating various wastewaters, in which case solids are filtered out, and solids (carriers or tangibles) of this type are discharged through an outlet formed under the cyclone separator. It was the way it was discharged.

This is a problem that the sand is precipitated by the cyclone action and the waste water is discharged together with the sand when discharged to the outside.

The screw conveyor at the front of the screw press is a conveying screw with a screw-shaped wing attached to its shaft to rotate various kinds of packages, for example grain grains, coal, ore, etc. by rotating in a gutter. In recent years, the package has been widely applied to all industrial fields such as environmental pollution prevention facilities and waste treatment facilities in each factory.

One of the drawbacks of the present invention is the combination of the screw press and the cyclone principle. Therefore, by applying the screw press-attached cyclone separator by the combination of the two devices to the apparatus for processing the fine matter, it attempts to solve the above-mentioned problems.

The present invention has been made in view of the above problems, and an object of the present invention is to provide an apparatus for automatically treating a contaminant for removing effluent and sediment in filthy water with a single device.

In order to achieve the above object, according to the present invention, the automatic sewage treatment device of the present invention comprises: a sewage treatment device for separating manure filthy water and sewage from the contaminant; and a primary separation tank provided with an inclined screen connected to at least two supply pipes. And cyclone separators for supplying sewage and sediment at a suitable flow rate to the cyclone separators, a screw press-attached cyclone separator having a screw press, and a primary separation tank and the screw press-attached cyclone separators. It is characterized by consisting of a secondary separation tank for filtering again.

In the above configuration, the primary separation tank may include an inclined screen installed inside, a plurality of guide plates provided on the lower side of the screen, and an inclined plate inclined in the opposite direction to the screen on the lower side of the guide plate. Preferably, the screw press is a cylindrical body, a screw shaft installed in the cylindrical body, a screw having a cut portion is installed in the screw shaft and the support is provided in the upper and lower parts to support the screw shaft to rotate smoothly, Preferably, the secondary separation tank is composed of a sediment filtration tank and a discharge tank compartment by partition walls, and the sediment filtration tank is provided with a barrier wall, an inclined plate, and a motor for transporting the sedimentation mole. Preferably, a pump driving motor is installed below the discharge tank.

Therefore, according to the above-mentioned method for automatically processing the contaminant, the large contaminant walks in the contaminant treatment machine and precipitates the remaining seeds or other contaminants such as heavy sand by the flow rate and separation plate flowing in the primary separation tank and pumps the sediment seeds. When the pressure is dropped to the secondary tank, and then sent to the cyclone, the fine cyclone is again precipitated according to the specific gravity in the cyclone, and the separated foreign matter is separated by transfer compression through a screw press and completely separated.

The effluent filtered in the next cyclone is again discharged to the discharge tank through the final sedimentation filtration tank, and if there is sand or other foreign matter in the sedimentation filtration tank, it is designed to send only the foreign matter back to the auxiliary tank for reprocessing. It can be separated and processed automatically, and the whole process can be done automatically, and there is almost no failure due to process shortening, which can reduce the budget for the workforce and management operation, and also reduce the manufacturing cost.

With the inlet to the primary separation tank 20 through the supply pipe (16).

The sewage introduced into the primary separation tank 20 is first filtered out of the settling mole on the screen 22 and is deposited on the inclined plate 26 by the guide plate 24.

The deposited precipitate is pumped by the motor M1 and is transferred to the auxiliary tank 30 through the transfer pipe 28. In the auxiliary tank 30, since the first and second inclined plates 32 and 34 are installed in the opposite directions for the effective sedimentation of the sediment, the sediment such as sand is subjected to the first and second purification. It is supplied to the cyclone main body 42 through the transfer pipe 36 connected to the separator 40 side.

Sediment and sewage introduced into the cyclone body 42 of the cyclone separator 40 are separated by centrifugal action. At this time, the sand particles 3㎛ or more is precipitated and dropped in the lower portion of the cyclone body (42). That is, the sewage separated from the sediment is moved to the upper side and supplied to the secondary separation tank 50 through the discharge pipe 48, and the sediment is deposited under the cyclone body 42. The deposited precipitate is conveyed upward by the screw press 46, and is accumulated in an external loading box not shown.

The sewage that reaches the secondary discharge chamber 54 is already purified by clean water because of the above process, and is discharged to the outside through the drain pipe 58 provided on the side wall of the secondary discharge chamber 54.

On the other hand, the motor (M3) is again by bypassing the deposit deposited on the bottom of the primary settling chamber 53 of the secondary separation tank 50 to the auxiliary tank 30 side through the bypass pipe (60). Purification process is required. Therefore, the degree of purification of the final drained water is increased.

In addition, the sediment deposited on the bottom of the secondary discharge chamber 54 by the motor M4 is bypassed to the contaminant treatment unit 10 through the bypass pipe 62, and is subjected to the purification process again. Therefore, the degree of purification of the final drained water is increased.
