Description

Technical area

The invention relates to the technical field of sewage treatment devices. It is an overflow type industrial sewage sedimentation device.

State of the art

With the rapid development of modern society, industry is also developing rapidly. At the same time as the development of industry, industrial sewage is a big problem. The arbitrary discharge of industrial wastewater pollutes the natural environment.

The sedimentation tank is a device for removing suspended matter in water according to the principle of sedimentation. It is often used in wastewater treatment. The cleaning and replacement of the sludge plate in today's sedimentation tanks are usually cumbersome, which often has a negative effect on the wastewater treatment effect.

Content of the invention

The present invention relates to an overflow type sedimentation apparatus for treating industrial waste water. It is intended to help solve the technical problem mentioned above.

The solution concept has the following structure: It comprises a device body in which a sedimentation tank is arranged in the middle. The lower end of the device body is provided with a drain.

In the sedimentation tank, a removable sludge plate is arranged at the bottom, with a spring sitting between the sludge plate and the bottom wall of the sedimentation tank. The lower area of the side walls of the sedimentation tank is each provided with a delimiting bulge which has an arcuate cross section. The mud plate presses the spring down and is held in the lower area of the sedimentation tank by the delimiting bulges. The four corners of the mud plate are each provided with a pull cord, and pull rings for winding up the pull cords are attached to the upper area of the side walls of the sedimentation tank.

An overflow weir is arranged on both sides of the upper end of the sedimentation tank and lies between the sedimentation tank and the device body. A filter element is arranged under each overflow weir.

The mouth end of the sedimentation tank is inclined and the inclination angle is 45 degrees.

The overflow weir is a metal overflow weir.

The two ends of the overflow weir are each firmly connected to the outer wall of the sedimentation tank and the inner wall of the device body.

This connection is made via several fastening blocks which are arranged evenly distributed on the outer wall of the sedimentation tank and the inner wall of the device body.

The overflow weir is firmly connected to the fastening blocks by welding or clamping.

The filter element is funnel-shaped.

1. 1. Die Schlammplatte im Sedimentationstank ist in einer abnehmbaren Art befestigt, wodurch die Reinigung und der Austausch vereinfacht werden. Zum Einbau der Schlammplatte wird sie gegen die Feder nach unten gedrückt, bis sie unter die begrenzenden Aufwölbungen einrastet. Zum Auswechseln wird die Schlammplatte mit den Zugseilen nach oben heraus gezogen. Zu normalen Zeiten werden die Zugseile auf die Zugringe an der Innenwand des Sedimentationstanks aufgewickelt.
2. 2. Das Mündungsende des Sedimentationstanks ist mit einem Winkel von 45 Grad geneigt. Das ist günstig für das Abfließen des Abwassers im Sedimentationstank beim Überlauf auf die ersten Befestigungsblöcke.
3. 3. Die Form des Filterelements ist trichterförmig und das Abwasser kann schnell durch das Filterelement gefiltert werden.

The particular advantages of the invention are listed as follows:

1. 1. The sludge plate in the sedimentation tank is attached in a detachable manner, which makes cleaning and replacement easier. To install the mud plate, it is pressed down against the spring until it snaps under the limiting bulges. To change it, the mud plate is pulled up and out with the pull cords. At normal times, the pull cords are wound onto the pull rings on the inner wall of the sedimentation tank.
2. 2. The mouth end of the sedimentation tank is inclined at an angle of 45 degrees. This is beneficial for the drainage of the waste water in the sedimentation tank when it overflows onto the first mounting blocks.
3. 3. The shape of the filter element is funnel-shaped and the waste water can be quickly filtered through the filter element.

The above description is only an overview of the technical concept of the present invention. In order to more clearly understand the technical methodology of this invention and to practice it in accordance with the content of the specification, the preferred embodiments of this invention will be described in detail below with the accompanying drawings. The specific implementation of this invention is set forth in detail by the following examples and drawings.

Detailed description

The principles and features of the present invention will now be described with reference to the accompanying drawings. The examples given are used only to illustrate this invention and are not intended to limit the scope of the invention. In the following paragraphs the invention is explained in more detail by way of example with reference to the drawings. The following description and the claims for protection are intended to show the advantages and features of this invention even more clearly. It should be noted that the drawings are in a simplified form and are not in exact proportions. They are only used to better explain the embodiments of the present invention.

As in the 1 and 2 As shown, the present invention provides an overflow type sedimentation apparatus for treating industrial waste water. It includes a device body 1 in which a sedimentation tank 101 is arranged in the middle. The lower end of the device body has a drain 109 Mistake.

There is a removable sludge plate in the sedimentation tank 102 placed on the ground, with a spring 103 sits between the sludge plate and the bottom wall of the sedimentation tank. The lower area of the side walls of the sedimentation tank is each with a delimiting bulge 104 provided, which has an arcuate cross-section. The mud plate pushes the spring down and is held in the lower area of the sedimentation tank by the delimiting bulges. The four corners of the mud plate are each with a pull rope 105 provided, and in the upper area of the side walls of the sedimentation tank there are pull rings 106 attached to wind up the pull cords.

There is an overflow weir on either side of the upper end of the sedimentation tank 107 disposed between the sedimentation tank and the device body. There is a filter element under each overflow weir 201 arranged.

The mouth end of the sedimentation tank 101 is tilted and the tilt angle is 45 degrees.

The overflow weir is a metal overflow weir.

The two ends of the overflow weir are each firmly connected to the outer wall of the sedimentation tank and the inner wall of the device body.

This connection is made using several mounting blocks 108 , which are arranged evenly distributed on the outer wall of the sedimentation tank and the inner wall of the device body.

The overflow weir is firmly connected to the fastening blocks by welding or clamping.

The filter element 201 is funnel-shaped.

The working principle and application of the present invention are as follows: the industrial waste water is introduced into the sedimentation tank and the impurities in the industrial waste water are deposited on the sludge plate; As the industrial wastewater continues to drain, it overflows from the top of the sedimentation tank into the overflow weirs; The wastewater is filtered through the filter element to retain the suspended matter therein; The wastewater is passed on to the next treatment via the drain.

Above are only the preferred embodiments of the present invention. They do not limit the invention in any way. Anyone skilled in the industry can implement this invention from the above drawings and description.
