Description

A sewage sedimentation tank structure

Technical field:

The invention relates to a sewage sedimentation tank structure.

Background technique:

During the extraction process of stevioside, a large amount of waste water will be generated, and the waste water will be accompanied by plant sediments.

Detailed ways:

The present invention will be further described below in conjunction with the accompanying drawings.

As shown in Fig. 1 to Fig. 3, a kind of sewage sedimentation pond structure of the present invention comprises pond body 1, partition wall 2, filter body 3, filter 4 and overflow pipe 5, and partition wall 2 is arranged in pond body 1, and partition The wall 2 divides the inner cavity of the pool body 1 into a first cavity 11 and a second cavity 12 , and the filter body 3 is arranged in the first cavity 11 . An overflow port is provided on the partition wall 2, and the overflow port is located below the filter body 3, and the first cavity 11 and the second cavity 12 are communicated through the overflow port. The bottom end of the overflow pipe 5 communicates with the overflow port, and the top end extends above the filter body 3 . The filter 4 is disposed in the second cavity 12, and the filter 4 is located above the overflow port.

The filter body 3 in the present invention includes an iron mesh frame and filter cotton, the iron mesh frame is rectangular, and the filter cotton is fixed in the iron mesh frame.

In order to install the filter body 3 in the first cavity 11, the two ends of the iron grid frame are provided with a second post, and the inner wall of the first cavity 11 is provided with a second support platform, and the second post is inserted into the first cavity. connected to the second support platform.

Filter 4 among the present invention comprises mounting plate 41, mounting rod 42, connecting rod 43, filter disc 44, filter screen 45 and steel wool 46, and mounting plate 41 is connected on the inwall of second cavity 12, and several mounting rods 42 Vertically fixed on the lower end face of the mounting plate 41, on each mounting rod 42, a number of connecting rods 43 are layered and fixed, on each connecting rod 43, a filter disc 44 is fixed, and the filter screen 45 is cylindrical, and each A filter screen 45 and several steel wool balls 46 are fixed on the lower end surface of the filter disc 44 , and the steel wool balls 46 are placed in the filter screen 45 .

For the convenience of connecting the steel ball 46 to the filter disc 44 , a plurality of fixed rods 47 are arranged on the lower surface of the filter disc 44 , and the steel ball 46 is fixed on the fixed rod 47 .

In order to install the filter 4 in the second cavity 12, the two ends of the mounting plate 41 are provided with a first post, and the inner wall of the second cavity 12 is provided with a first supporting platform, and the first post is inserted into the second cavity. connected to the first support platform.
