Technical Field
[0001] The utility model relates to the technical field of sewage sampling, in particular to a sewage sampling device for sewage treatment. Background Technique
[0002] At present, water pollution sampling, also known as water pollution sampling, refers to the process of extracting water samples from polluted water quality according to specified methods and a certain proportion. By detecting and analyzing the extracted water samples, relevant water quality parameters such as the degree of water pollution, the types and contents of pollutants can be determined, so as to guide production activities and take relevant measures to reduce water pollution.
[0003] Among them, with the rapid development of society, although our economic level has been greatly improved, there are also many negative impacts, and environmental damage is one of them. The most obvious is the pollution of rivers, lakes and seas. Therefore, the collection of sewage from rivers, lakes and seas is very important.
[0004] The most common sampling method on the market is to place the sampling box at the sampling site and wait for the sewage to flow into the sampling box automatically. However, during the continuous introduction of sewage into the sampling box, a large amount of silt and impurities will also be introduced into the sampling box, which is very easy to block the sampling port. Therefore, new technical solutions need to be designed to solve this problem, which can avoid the blockage of the sampling box during the sampling process. Content of the Utility Model
[0005] The purpose of the utility model is to provide a sewage sampling device for sewage treatment, which solves the problems raised in the background technique.
[0006] To achieve the above purpose, the utility model provides the following technical solution: a sewage sampling device for sewage treatment, including a sampling tank, a sampling port is opened on one side of the bottom of the sampling tank, a cover is fitted on one side of the sampling port, a limiting ring is fixedly installed in the middle of the bottom side inside the sampling tank, and an anti-blocking mechanism is installed in the limiting ring;
[0007] The anti-blocking mechanism includes a resisting rod movably installed in the limiting ring, a first spring sleeved on one side of the resisting rod, a blade fixedly installed on the other side of the resisting rod, an extrusion air bag fixedly installed at one end of the bottom side of the sampling tank, an air discharge pipe communicated and installed on one side inside the extrusion air bag, and an air inlet pipe communicated and installed on the other side inside the extrusion air bag.

A sealing rubber pad is sleeved on the outer wall of the sealing plate, and a second spring is sleeved on the outer wall of the two groups of limit rods. The two groups of the second springs are respectively fixed to the sealing plate and the side wall of the sampling tank, so as to control the negative pressure inside the sampling tank.
[0011] As an optional solution of the technical solution of the present application, a three-way joint is installed on the top of the side wall of the sampling tank, one component interface of the three-way joint is installed on the inflation pipe, and the other component interface of the three-way joint is installed on the intake pipe.

Repeatedly pulling the blades on the push rod back and forth can prevent the sludge inside the sewage pool from clogging the sampling port, thereby greatly improving the sampling success rate of the sampling tank.
[0015] 2. The technical solution of the present application is to have limit rods fixedly installed at both ends of the top side of the interior of the sampling tank, and sealing plates are movably installed at the other ends of the two sets of limit rods. When the inflation tube is connected to an external air pump, the bottom side of the interior of the sampling tank is continuously filled with gas, and the sealing plate on the limit rod is squeezed to the bottom side of the sampling tank. The upper cover of the sampling port and the solenoid valve on the inflation tube are opened, so that the gas on the top side of the interior of the sampling tank can be discharged and the sealing plate can be pushed to move slowly upward, so that negative pressure is formed on the bottom side of the interior of the sampling tank, and the sewage inside the sewage pool is quickly drawn in, which greatly improves the efficiency of sewage sampling.

The two groups of second springs 32 are fixedly installed on the sealing plate 31 and the side wall of the sampling tank 1 respectively, which can control the negative pressure inside the sampling tank 1.
[0024] In this technical solution, when the charging pipe 34 is connected to an external air pump, the bottom side of the sampling tank 1 is continuously filled with gas, and the sealing plate 31 on the limiting rod 3 is pressed against the bottom side of the sampling tank 1. The cover 12 on the sampling port 11 and the solenoid valve on the charging pipe 34 are opened, the gas on the top side of the sampling tank 1 can be discharged, the sealing plate 31 is pushed to slowly move upward, a negative pressure is formed on the bottom side of the sampling tank 1, and the sewage in the sewage tank is quickly pumped in, greatly improving the efficiency of sewage sampling.

[0030] During use, first, limiting rods 3 are fixedly installed at both ends of the inner top side of the sampling tank 1, and a sealing plate 31 is movably installed at the other ends of the two groups of limiting rods 3. When the charging pipe 34 is connected to an external air pump, the inside of the bottom side of the sampling tank 1 is continuously filled with gas, and the sealing plate 31 on the limiting rod 3 is pushed to the bottom side of the sampling tank 1. By opening the cover 12 on the sampling port 11 and the solenoid valve on the charging pipe 34, the gas on the inner top side of the sampling tank 1 can be discharged, pushing the sealing plate 31 to slowly move upward, creating a negative pressure on the inner bottom side of the sampling tank 1 and quickly pumping the sewage in the sewage tank into it, greatly improving the efficiency of sewage sampling. At the same time, the operator holds the lifting rope 13 of the sampling tank 1 and places the sampling tank 1 in the sewage tank where sampling is required. Meanwhile, the driver controls the solenoid valves on the intake pipe 26 and the discharge pipe 25. This can not only introduce the air on the inner top side of the sampling tank 1 into the extrusion airbag 24 to squeeze the abutting rod 21, but also when the extrusion airbag 24 discharges the gas in cooperation with the discharge pipe 25, the extrusion rod will automatically reset due to the pulling force of the first spring 22. Repeating this process can reciprocally move the blade 23 on the abutting rod 21, preventing the sludge in the sewage tank from blocking the sampling port 11 and greatly increasing the sampling success rate of the sampling tank 1.
