Description

Aerated grit chamber provided with fine grid

Technical Field

The present application relates to the technical field of aerated grit chambers, and in particular to an aerated grit chamber provided with fine grids.

Background Art

Grit chambers are usually set before pump stations or initial sedimentation tanks to remove particles with larger particle sizes to protect pipes, valves and other facilities from wear and blockage. Aerated grit chambers are a common type of grit chamber. Through aeration, organic particles in wastewater are often suspended. Sand particles rub against each other and withstand the shear force of aeration. Organic pollutants attached to sand particles can be removed, which is conducive to obtaining relatively pure sand particles. Sand particles fall into the grit chamber and are separated from water by a gantry truck pump suction sand suction machine and a sand-water separator.

A fine screen is usually installed inside the aerated grit tank to filter out debris in the sewage. However, when the fine screen is filtering debris, some lighter and softer waste (such as plastic bags, cloth, etc.) can easily hang on the fine screen, causing blockage of the fine screen, reducing the filtering effect of the fine screen and affecting the use of the aerated grit tank.

Therefore, there is an urgent need for an aerated grit chamber provided with a fine grid to solve the problem that the fine grid is easily blocked by lighter and softer wastes.

Utility Model Content

In view of the shortcomings of the prior art, the present application provides an aerated grit chamber provided with a fine grid, which has the advantage of being easy to scrape away debris and solves the problem that light and soft waste easily clogs the fine grid.

To achieve the above-mentioned purpose, the present application provides the following technical solutions: an aerated grit chamber provided with a fine grid, comprising an aerated grit chamber body, a fine grid body and an aeration pipe, wherein the fine grid body and the aeration pipe are arranged inside the aerated grit chamber body, a scraping mechanism is arranged on the front of the fine grid body, and a stirring mechanism is arranged inside the aerated grit chamber body;

The scraping mechanism includes a driving motor, a connecting rod, a connecting ring and a scraping rod. The driving motor is arranged on one side of the fine grid body. One end of the connecting rod is fixedly connected to the output end of the driving motor, and the other end of the connecting rod is rotatably connected to the inner side of the fine grid body plate. Several groups of connecting rings are welded to the outer surface of the connecting rod, and three groups of scraping rods are welded to the outer surface of the connecting ring.

When the connecting rod rotates, the scraper rod is driven to rotate through the connecting ring. When the scraper rod rotates, the debris hanging on the fine screen body is scraped off, making it difficult for lighter and softer waste to adhere to the outside of the fine screen body and cause blockage of the fine screen body, thereby reducing the debris in the sewage.

Preferably, several groups of connecting rings are linearly distributed on the outer surface of the connecting rod.

Preferably, the connecting rod is connected to the plate body of the aerated grit chamber body through a bearing.

Preferably, the stirring mechanism includes a support plate, a second drive motor, a connecting column and a stirring rod, three groups of the support plates are welded to the inner side of the aeration grit chamber body, the second drive motor is arranged in the middle position of the top of the support plate, one end of the connecting column is fixedly connected to the output end of the second drive motor, and several groups of the stirring rods are welded to the outer surface of the connecting column.

Preferably, several groups of stirring rods are evenly distributed on the outer surface of the connecting column.

Preferably, the three groups of support plates are linearly distributed on the inner side of the aerated grit chamber body.

In summary, the present application includes at least one of the following beneficial effects:

1. In the aerated grit tank provided with a fine grid, when the connecting rod rotates, the scraper rod is driven to rotate through the connecting ring. When the scraper rod rotates, the debris hanging on the fine grid body is scraped off, so that lighter and softer waste is not easy to adhere to the outside of the fine grid body and cause blockage of the fine grid body, thereby reducing the debris in the sewage and allowing the aerated grit tank body to better settle sand.

2. The aerated grit tank equipped with a fine grid stirs the sewage by rotating the stirring rod driven by the connecting column, so that the bubbles generated by the aeration pipe are separated by the stirring rod, making the bubbles more dispersed, so that the aerated grit tank body can better remove impurities attached to the sand, allowing the aerated grit tank body to be better used.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

Please refer to Figures 1-4, an aerated grit tank equipped with a fine grid includes an aerated grit tank body 1, a fine grid body 2 and an aeration pipe 3, the fine grid body 2 and the aeration pipe 3 are arranged on the inner side of the aerated grit tank body 1, a scraping mechanism is arranged on the front side of the fine grid body 2, and a stirring mechanism is arranged on the inner side of the aerated grit tank body 1.

Through the above technical solution, the sewage entering the aerated grit tank body 1 has the sand in the sewage removed by the aeration generated by the aeration pipe 3, and the debris in the sewage is filtered by the fine grid body 2, so that the aerated grit tank body 1 completes the treatment of the sewage.

Specifically, the scraping mechanism includes a driving motor 111, a connecting rod 112, a connecting ring 113 and a scraping rod 114. The driving motor 111 is arranged on one side of the fine screen body 2. One end of the connecting rod 112 is fixedly connected to the output end of the driving motor 111, and the other end of the connecting rod 112 is rotatably connected to the inner side of the plate body of the fine screen body 2. Several groups of connecting rings 113 are welded to the outer surface of the connecting rod 112. The connecting rod 112 is connected to the plate body of the aerated grit chamber body 1 through a bearing. Three groups of scraping rods 114 are welded to the outer surface of the connecting ring 113. Several groups of connecting rings 113 are located on the outer surface of the connecting rod 112 and are linearly distributed.

Through the above technical solution, when the fine screen body 2 is filtering debris in sewage, when lighter and softer waste is hung on the fine screen body 2, the staff can start the driving motor 111, and the driving motor 111 drives the connecting rod 112 to rotate, and the connecting rod 112 drives the scraper rod 114 to rotate through the connecting ring 113. When the scraper rod 114 rotates, the debris hanging on the fine screen body 2 is scraped off, so that the lighter and softer waste is not easy to adhere to the outside of the fine screen body 2 and cause blockage to the fine screen body 2, thereby reducing the debris in the sewage and allowing the aerated grit tank body 1 to better settle sand.

Specifically, the stirring mechanism includes a support plate 211, a second drive motor 212, a connecting column 213 and a stirring rod 214. Three groups of support plates 211 are welded to the inner side of the aeration grit chamber body 1. The second drive motor 212 is arranged in the middle position of the top of the support plate 211.
