Abstract

This utility model discloses a rotary decanter, characterized in that a float is welded to one end of a fixed baffle plate, and a decanting weir is installed at the other end via a float shaft. Three water collection branch pipes are welded to the lower end of the decanting weir, and the other ends of the branch pipes are welded to a main water collection pipe. One end of the main water collection pipe is fixed to the bottom of the pool via an underwater shaft, and the other end passes through a packing seal chamber on the pool wall. One end of the outlet pipe is fitted with a spring telescopic tube and is fixedly connected to the main water collection pipe via a packing gland installed in the packing seal chamber. One end of the connecting rod and the hoist push rod are respectively mounted on a push pulley via a shaft, and the other end of the connecting rod is fixed to the water collection branch pipe via a shaft. With the above configuration, this utility model can effectively block impurities in the supernatant in the pool, ensuring the overflow of the supernatant and reducing the pressure on the next process caused by overflowing impurities. Moreover, it is simple and convenient to install, reducing installation costs.

Description

a rotary decanter

technical field

The utility model relates to a water decanter for treating sewage, in particular to a water decanter with a rotatable bottom and easy installation.

Background technique

At present, the outflow of the supernatant in the sewage treatment adopts the method of overflowing the overflow weir, but due to the influence of the pool, the pool body is generally constructed in the open air, so there are some impurities in the pool body during the overflow process. The overflow weir enters the next sewage treatment process, and the overflowing impurities bring pressure to the next process. In addition, because the installation accuracy of the outlet rotary joint of the ordinary decanter is very high, the cost of the equipment is too high and the investment is too high.

Contents of the invention

The purpose of the utility model is to provide a decanter which is easy to install and has less impurities in the overflow.

In order to achieve the above purpose, the utility model welds the buoy at one end of the buoy fixed baffle, and installs a decanter weir through the buoy shaft at the other end, and welds three branch pipes communicating with it at the lower end of the decanter weir respectively. The other end of the water collection branch pipe is welded on the water collection main pipe and communicated with the water collection main pipe. One end of the water collection main pipe is fixed on the bottom of the pool through an underwater rotating shaft, and the other end passes through the packing seal chamber on the pool wall. The outlet pipe One end of the spring is set with a spring telescopic tube, and is fixedly connected to the water collection main pipe through the packing gland installed in the packing sealing chamber, the push pulley rail is installed on the side wall of the pool, and the opening and closing is installed on the pool above the push pulley rail Machine, the push pulley is installed in the slideway of the push pulley rail, and one end of the connecting rod and the gate hoist push rod is respectively installed on the push pulley through the rotating shaft, and the other end of the connecting rod is fixed on the water collecting branch pipe through the rotating shaft.

Through the above settings, the utility model can effectively block the impurities in the supernatant in the pool, ensure the overflow of the supernatant in the pool, reduce the pressure brought by the overflow impurities to the next process, and the installation is simple and convenient. Reduced installation costs.

Detailed ways

As shown in Figures 1, 2, and 3, the utility model welds the buoy 2 at one end of the buoy fixed baffle 1, and installs the decanting weir groove 4 through the buoy rotating shaft 3 at the other end, and welds the lower ends of the decanting weir groove 4 respectively. Three water collection branch pipes 5 communicating with it, the other end of the water collection branch pipe 5 is welded on the water collection main pipe 6 and communicated with the water collection main pipe 6, and one end of the water collection main pipe 6 is fixed on the bottom of the pool by an underwater rotating shaft 7 8. The other end passes through the packing sealing chamber 9 on the wall of the pool 8, and one end of the outlet pipe 10 is fitted with a spring telescopic tube 11, and is fixedly connected to the water collection main pipe 6 through the packing gland 12 installed in the packing sealing chamber 9 , the push pulley rail 13 is installed on the side wall of the pool 8, the hoist 14 is installed on the pool 8 above the push pulley rail 13, the push pulley 15 is installed in the slideway of the push pulley rail 13, the connecting rod 16 is connected with the headstock One end of machine push rod 17 is installed on the push pulley 15 by rotating shaft respectively, and the other end of connecting rod 16 is fixed on the water collecting branch pipe 5 by rotating shaft.

Through the above settings, the up and down movement of the hoist push rod 17 of the hoist 14 drives the push pulley 15 to slide up and down in the slideway of the push pulley rail 13, and then drives the connecting rod 16 to make the water collecting branch pipe 5 rotate around the underwater shaft 7. Rotational movement, during this process, the buoyancy of the buoyancy drum 2 rotates around its buoy shaft 3 to always block the impurities at the periphery of the decanting weir tank 4, reducing the impurities overflowing into the water in the decanting weir tank 4, and the packing is sealed The chamber 9 is used in conjunction with the spring telescopic tube 11, which not only ensures the airtightness of the output end of the pool 8, but also reduces the installation accuracy requirements and facilitates installation.
