detailed description

In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in this application will be clearly and completely described below in conjunction with embodiments.

As shown in Figures 1-3, the present invention discloses a combined pretreatment device, including a pipeline main body 1; the pipeline main body 1 includes a main pipeline 2 and two branch pipelines 3, and the two branch pipelines 3 are respectively The first branch pipeline 31 and the second branch pipeline 32; the main pipeline 2 includes several connecting pipes 21, three-way joints A22, three-way joints B23 and three-way joints C24 arranged from bottom to top, and the three-way joints A , B, C, that is, the labels 22-24 are respectively connected through the connecting pipe 21; the first branch pipeline 31 is connected to the tee joint A22, and the second branch pipeline 32 is connected to the tee joint C24, which runs through the tee There is a float 4 inside the joints B and C, the float can float up and down inside the three-way joint B, that is, the label 23, and the float 4 is supported on the connecting pipe 21 located on the upper part of the three-way joint C24 through the plug cap 41 and the nut 42; The three-way joint B23 is provided with a sampling port 231 and a first backwash port 232 .

The device has a simple structure, not only has sampling and washing functions, but also has an alarm function. The float installed on the upper part of the device is equipped with a sensor. The sensor interacts with the external information collection center by collecting the movement information of the float to judge whether the device is working normally.

The upper end of the tee joint B23 is sequentially connected to the lower end of the tee joint C24 through the bushing 25 and the connecting pipe 21 .

The water outlet of the three-way joint B23 is provided with a plug 233 , and the water inlet of the plug 233 is provided with a filter 234 , and the sampling port 231 and the first backwash port 232 are provided through the plug 233 .

The filter 234 is fixed on the plug 233 through the steel mesh fixing piece 235, and the setting of the filter is mainly for filtering and extracting sundries in the water sample.

The upper part of the three-way joint A22 is connected to the lower end of the three-way joint B23 through the connecting pipe 21 , the large and small joints 26 and the second connecting pipe 27 respectively.

The size joint 26 is provided with a second backwash port 261, and the second backwash port 261 is used for flushing the entire pipeline.

The first branch pipeline 31 is provided with a ball valve 311 for controlling the flow of water, and the ball valve 311 controls the amount of water in the branch pipeline so that it flows to the upper part of the main pipeline 2 .

The sampling port 231 , the first backwash port 232 and the second backwash port 261 are respectively provided with a pagoda joint 5 connected to the outside.

The float 4 is provided with a sensor, and the sensor is connected to an external information collection center by signal.

As shown in Figure 4, it is a flow diagram of the liquid in the device. In this figure, the orientation of the processing device is: in a vertical state, point A faces the ground, and point E faces the sky.

The direction of water flow is:

(1) When sampling: point A is the water inlet for pretreatment, the water flows into point B along the direction of the arrow, and after reaching point B, it flows to point C, and the ball valve at point C controls the flow of water to force the water to flow in the direction of point D , after arriving at point D, it flows to port F through the filter screen 234, and water samples are taken into the device through port F, most of the water flows through point D and continues to point E, and finally flows away from the second branch pipeline 32.

(2) When sampling is stopped: the water flow flows away from the first and second pipelines 31 and 32, that is, flows out from the direction of point C and point E in the figure until there is no water in the pipe.

The alarm system is: when the equipment is in operation, when the water flow reaches or is higher than point D, the float at point D rises due to buoyancy, and the information about the normal operation of the pretreatment can be transmitted to the information center, indicating normal operation; when the water flow is lower than At point D, the float does not float up. There are two possibilities. One is that the sampling stage is not at this time, and the other is that the preprocessing fails.

The cleaning system is: when the equipment is not sampling, the first backwash port 232 and the second backwash port 261 are flushed with a water pump and an air pump, that is, the G port and the H port in the figure, and the G port flushes the filter screen to keep the filter screen clean , try not to affect the next sampling measurement value, the H port flushes the entire pipeline, blows away impurities, keeps the tube clean, and tries not to affect the next sampling measurement value.

The combined pretreatment device of the present invention has a simple and clear structure, is easy to maintain, and is not easy to cause blockage; moreover, a float is added to the pretreatment pipeline, which is convenient for maintenance personnel to monitor whether the pretreatment device is running; the simple and reasonable structure makes the maintenance cost and manufacturing cost They are all greatly reduced, and are easy to install, without restrictions on construction conditions.

The described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
