Technical Field

[0001] The utility model relates to the technical field of water quality monitoring, in particular to an online ammonia nitrogen analyzer. Background Art

[0002] The online ammonia nitrogen analyzer can monitor the concentration of ammonia nitrogen in sewage, surface water or municipal water online. When using the online ammonia nitrogen analyzer, it is often necessary to filter the water. The online ammonia nitrogen analyzer can monitor the flow of ammonia nitrogen to calculate the pollutant flux.

[0003] The patent document with publication number CN 205620205 U discloses an online ammonia nitrogen analyzer filtration system, including a filtration system and an online analyzer, the filtration system including a submersible pump and an overflow pipe, the submersible pump is connected to a three-way interface through a water pipe, one end of the three-way interface is connected to a first regulating valve through a water pipe, the other end of the three-way interface is connected to a second regulating valve through a water pipe, a Y-type filter is provided on the first pipeline, the Y-type filter is connected to a one-way stop valve, the one-way stop valve is connected to an oil-free air compressor, the first pipeline is connected to the second pipeline, a third regulating valve and a sampling cup are provided on the second pipeline, and the sampling cup is connected to the online analyzer.

[0004] The above patent documents still have the following deficiencies in practical application:

[0005] When testing water quality, there may be impurities and other garbage in the water. The device needs to be cleaned from time to time to prevent the water quality from being contaminated, which will affect the final test results. However, there are many irregular shapes inside the device, which is easy to be missed during the cleaning process and cannot be cleaned thoroughly. Based on this, an online ammonia nitrogen analyzer is proposed. Utility Model Content

[0006] The purpose of the utility model is to provide an online ammonia nitrogen analyzer to solve the problems raised in the above background technology.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] An online ammonia nitrogen analyzer comprises an analysis box, a base is installed at the bottom end of the analysis box, an analysis inner box is arranged inside the analysis box, a support plate is connected to one side of the base, a contact rod is arranged at the top of the base, a display screen is installed at the top of the support plate, a water inlet pipe is arranged on one side of the analysis box, a fixing plate is connected to one side of the analysis inner box, a threaded column is connected to one side of the fixing plate, one end of the threaded column is connected to the output end of a fixed motor, and a sliding plate is installed on the other side of the analysis box.

[0009] Preferably, a processing terminal is provided inside the base, the contact rod passes through the analysis box and the inner analysis box, and the display screen is electrically connected to the base via a circuit inside the support plate.

[0010] Preferably, the water inlet pipe passes through the inner analysis box, a groove is provided at the top of the analysis box, the size of the groove matches the fixed plate, the sliding plate is symmetrically arranged, and a convex groove is provided on the opposite side, which is the same shape as the fixed plate.

[0011] Preferably, a fixing block is installed on one side of the fixed motor, and the fixed motor is fixedly connected to the sliding board via the fixing block.

[0012] Preferably, a handle is installed on the top of the analysis inner box, a rotating shaft is provided on one side of the analysis inner box, and a clamping plate is provided inside the analysis box.

[0013] Preferably, the clamping plate and the rotating shaft are symmetrically arranged, and the clamping plate and the rotating shaft are clamped with each other to form a rotational connection relationship.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. By turning on the fixed motor, the fixed motor drives the threaded column at the output end to rotate, and the fixed plate threadedly connected to the threaded column is restricted by the sliding plates on both sides and cannot rotate synchronously with the threaded column, so the fixed plate moves horizontally along the extension direction of the threaded column, and when the fixed plate moves to the end toward the analysis inner box, the analysis inner box will be fixed, otherwise the fixing effect of the analysis inner box will be cancelled, because the threaded column and the analysis inner box do not contact each other. Then, when the operator tests the next batch of water quality samples, the fixing effect of the analysis inner box can be cancelled, and the analysis inner box can be replaced with a new one, while the old analysis inner box is taken for cleaning, thereby preventing the analysis inner box from being not cleaned thoroughly and affecting the final water quality test results, thereby ensuring the rigor and accuracy of the test results.

[0016] 2. By rotating the connecting plates and the rotating shaft on both sides of the analysis inner box, the rotating shaft rotates along the connecting plates. The analysis inner box can be directly lifted out by pulling the handle on the top of the connecting plate and replaced with a new one. This increases the convenience of the device, saves the operator's time and energy in replacing the analysis inner box, and improves the overall work efficiency of the replacement operation.
