Description

Technical Field

[0001] This utility model relates to the field of water quality testing technology, specifically to a pre-screening treatment instrument based on the determination of ammonia nitrogen capacity in water. Background Technology

[0002] Water quality testing encompasses wastewater, pure water, seawater, fishery water, swimming pool water, reclaimed water, bottled purified water, natural mineral drinking water, cooling water, agricultural irrigation water, landscaping water, domestic drinking water, groundwater, boiler water, surface water, industrial water, and laboratory water. Ammonia nitrogen capacity determination is a crucial water quality test item. The commonly used method for ammonia nitrogen capacity determination is Nessler's reagent spectrophotometry. Factors such as calcium, magnesium, and iron ions, sulfides, aldehydes and ketones, color, and turbidity can interfere with the determination. Therefore, water samples need to be pretreated before testing. Flocculation and sedimentation methods have a significant effect on turbidity removal during pretreatment.

[0003] A search (application number: CN202120067251.7) reveals a pre-screening treatment instrument based on ammonia nitrogen capacity determination in water, comprising a flocculation chamber. A liquid inlet hole is provided on one inner wall of the flocculation chamber, and a liquid inlet pipe is fixedly connected to the inner wall of the liquid inlet hole. An installation hole is provided at the bottom of the flocculation chamber, and a rotating shaft is rotatably connected to the inner wall of the installation hole. A stirring blade is fixedly sleeved on the outer wall of the rotating shaft. In the process of developing this utility model, the inventors discovered the following unresolved problem in the prior art: although the device has good screening function, because the filter screen is pressed down from top to bottom, a large portion of suspended matter adheres to the bottom of the filter screen and cannot be removed, affecting the subsequent treatment effect. Utility Model Content

[0004] This invention provides a pre-screening treatment instrument based on the determination of ammonia nitrogen capacity in water, which can overcome some or all the defects of the prior art.

[0005] According to the present invention, a pre-screening treatment instrument based on the determination of ammonia nitrogen capacity in water includes an instrument body, the instrument body including a tank, a flocculation chamber formed inside the tank, a screening component slidably arranged in the vertical direction inside the flocculation chamber, the screening component including a sieve plate, a cleaning component rotatably arranged on the bottom wall of the sieve plate, and a mixing component arranged on the bottom wall of the flocculation chamber. The mixing component is used to mix the solution in the flocculation chamber and drive the cleaning component to clean the bottom wall of the sieve plate.

[0006] In use, this invention presses the sieve plate down to push the suspended matter in the solution to the bottom of the flocculation chamber, so that the cleaning component at the bottom wall of the sieve plate cooperates with the mixing component. Then, the mixing component drives the cleaning component to clean the suspended matter at the bottom wall of the sieve plate, effectively preventing sieve plate blockage, ensuring the screening effect, and avoiding affecting the next filtration effect.

[0007] Understandably, by combining the mixing component and the cleaning component, the mixing component can simultaneously mix and stir the solution while also working with the cleaning component to clean the bottom wall of the sieve plate, thus achieving the dual functions of mixing and cleaning.

[0008] Preferably, a connecting column penetrating the top of the flocculation chamber is provided at the top wall of the sieve plate, a top plate is formed at the top wall of the connecting column, an installation frame is provided at the tank body, a cylinder is provided at the installation frame, and the top plate is located at the telescopic end of the cylinder.

[0010] Preferably, the mixing component includes a rotating shaft that is rotatably disposed at the bottom wall of the flocculation chamber along the axial direction of the sieve plate. A motor is provided at one end of the rotating shaft that passes through the bottom wall of the flocculation chamber. The rotating shaft is provided with stirring blades and scraper arms at the flocculation chamber. The stirring blades are used to stir the solution in the flocculation chamber, and the scraper arms are used to clean the bottom wall of the flocculation chamber.

[0011] By combining the stirring blades and scraper arms, the solution in the flocculation chamber is thoroughly stirred while the bottom wall of the flocculation chamber is cleaned, thereby improving the mixing effect of the solution.

[0012] Understandably, the scraper arm can assist in cleaning slag during slag removal.

[0013] Preferably, an extension arm is formed at the top wall of the scraper arm that contacts the side wall of the flocculation chamber, and the height of the top wall of the extension arm is lower than the height of the top wall of the stirring blade.

[0014] The above structure allows the scraper arm and extension arm to clean the bottom and side walls of the flocculation chamber simultaneously, preventing floating matter from adhering to the side and bottom walls of the flocculation chamber and affecting the next filtration effect.

[0015] Preferably, the cleaning component has a connecting block that is rotatably disposed on the bottom wall of the screen plate along the axial direction of the screen plate, a cleaning arm that contacts the bottom wall of the screen plate is formed on the side wall of the connecting block, and an inwardly recessed spline groove is formed on the bottom wall of the connecting block; an extension shaft is formed on the top wall of the rotating shaft, and a spline that mates with the spline groove is formed on the outer wall of the extension shaft.

[0016] With the above structure, when the screen plate is pressed down, the spline groove at the cleaning part can engage with the spline, thereby driving the cleaning part to rotate and clean the bottom wall of the screen plate. No additional drive is required to drive the cleaning part to rotate.

[0017] Understandably, the engagement of splines and spline slots enables a stable connection and power transmission between the shaft and the cleaning component.

[0018] Preferably, a liquid addition pipe and a pH detection pipe communicating with the flocculation chamber are formed on the outer wall of the tank, and both the liquid addition pipe and the pH detection pipe are located below the sieve plate.

[0019] The above structure ensures that the added solution is located below the sieve plate, preventing suspended matter in the solution from being located above the sieve plate.

[0020] Preferably, a slag discharge pipe communicating with the flocculation chamber is formed at the bottom wall of the tank; a water discharge pipe communicating with the flocculation chamber is formed at the outer wall of the tank, and the water discharge pipe is located above the stirring blades.

[0021] The slag discharge pipe is located at the bottom wall of the tank and is connected to the inside of the flocculation chamber, so that the floating matter formed after the flocculation process is completed can be discharged through the slag discharge pipe.

[0022] Understandably, the water outlet pipe is located above the stirring blades, so that after the sieve plate is engaged with the mixing components, the water outlet pipe is located above the sieve plate, thus allowing the solution filtered through the sieve plate to be discharged again.

[0030] Please see Figure 1-5This embodiment provides a pre-screening treatment instrument based on the determination of ammonia nitrogen capacity in water. It includes an instrument body 100, which includes a tank 110. A flocculation chamber 210 is formed inside the tank 110. A screening component 120 is slidably arranged vertically inside the flocculation chamber 210. The screening component 120 includes a sieve plate 240. A cleaning component 230 is rotatably arranged on the bottom wall of the sieve plate 240. A mixing component 220 is arranged on the bottom wall of the flocculation chamber 210. The mixing component 220 is used to mix the solution in the flocculation chamber 210 and drive the cleaning component 230 to clean the bottom wall of the sieve plate 240.

[0031] This disclosure discloses a pre-screening treatment instrument based on the determination of ammonia nitrogen capacity in water. During use, the sieve plate 240 is pressed down to push the suspended solids in the solution to the bottom of the flocculation chamber 210, so that the cleaning component 230 at the bottom wall of the sieve plate 240 cooperates with the mixing component 220. Then, the mixing component 220 drives the cleaning component 230 to clean the suspended solids at the bottom wall of the sieve plate 240, effectively preventing the sieve plate 240 from clogging, ensuring the screening effect, and avoiding affecting the subsequent filtration effect.

[0032] It is understandable that by combining the mixing component 220 and the cleaning component 230, the mixing component 220 can mix and stir the solution while also working with the cleaning component 230 to clean the bottom wall of the sieve plate 240, thus achieving the dual functions of mixing and cleaning.

[0033] In this embodiment, a connecting column 250 penetrating the top of the flocculation chamber 210 is provided at the top wall of the sieve plate 240, and a top plate 260 is formed at the top wall of the connecting column 250. An installation frame is provided at the tank body 110, and a cylinder 270 is provided at the installation frame. The top plate 260 is located at the telescopic end of the cylinder 270.

[0034] Stable screening is achieved by driving the top plate 260 and screen plate 240 to rise and fall with the cylinder 270, reducing manual operation.

[0035] In this embodiment, the mixing component 220 includes a rotating shaft 410 rotatably disposed at the bottom wall of the flocculation chamber 210 along the axial direction of the sieve plate 240. A motor 420 is provided at one end of the rotating shaft 410 that passes through the bottom wall of the flocculation chamber 210. The rotating shaft 410 is provided with a stirring blade 440 and a scraper arm 430 at the flocculation chamber 210. The stirring blade 440 is used to stir the solution in the flocculation chamber 210, and the scraper arm 430 is used to clean the bottom wall of the flocculation chamber 210.

[0036] By combining the stirring blades 440 and the scraper arm 430, the solution in the flocculation chamber 210 is thoroughly stirred while the bottom wall of the flocculation chamber 210 is cleaned, thereby improving the mixing effect of the solution.

[0037] Understandably, scraper arm 430 can assist in slag removal during slag discharge.

[0038] In this embodiment, an extension arm 431 is formed on the top wall of the scraper arm 430, which contacts the side wall of the flocculation chamber 210. The height of the top wall of the extension arm 431 is lower than the height of the top wall of the stirring blade 440.

[0039] The above structure allows the scraper arm 430 and the extension arm 431 to clean the bottom and side walls of the flocculation chamber 210 simultaneously, preventing floating matter from adhering to the side and bottom walls of the flocculation chamber 210 and affecting the next filtration effect.

[0040] In this embodiment, the cleaning component 230 has a connecting block 310 rotatably disposed on the bottom wall of the screen plate 240 along the axial direction of the screen plate 240. A cleaning arm 320 is formed on the side wall of the connecting block 310 that contacts the bottom wall of the screen plate 240. An inwardly recessed spline groove 330 is formed on the bottom wall of the connecting block 310. An extension shaft is formed on the top wall of the rotating shaft 410. A spline 450 that mates with the spline groove 330 is formed on the outer wall of the extension shaft.

[0041] With the above structure, when the screen plate 240 is pressed down, the spline groove 330 at the cleaning component 230 can cooperate with the spline 450, thereby driving the cleaning component 230 to rotate and clean the bottom wall of the screen plate 240. The cleaning component 230 can be driven to rotate without additional drive.

[0042] Understandably, the engagement of spline 450 and spline groove 330 achieves a stable connection and power transmission between the rotating shaft 410 and the cleaning component 230.

[0043] In this embodiment, a liquid addition pipe 130 and a pH detection pipe 140 communicating with the flocculation chamber 210 are formed on the outer wall of the tank body 110. Both the liquid addition pipe 130 and the pH detection pipe 140 are located below the sieve plate 240.

[0044] The above structure ensures that the added solution is located below the sieve plate 240, preventing suspended matter in the solution from being located above the sieve plate 240.

[0045] In this embodiment, a slag discharge pipe 520 communicating with the flocculation chamber 210 is formed at the bottom wall of the tank body 110; a water discharge pipe 510 communicating with the flocculation chamber 210 is formed at the outer wall of the tank body 110, and the water discharge pipe 510 is located above the stirring blade 440.

[0046] The slag discharge pipe 520 is located at the bottom wall of the tank 110 and is connected to the interior of the flocculation chamber 210, so that the floating matter formed after the flocculation process is completed can be discharged through the slag discharge pipe 520.

[0047] It is understandable that the outlet pipe 510 is located above the stirring blade 440, so that after the sieve plate 240 is engaged with the mixing component 220, the outlet pipe 510 is located above the sieve plate 240, thereby allowing the solution filtered through the sieve plate 240 to be discharged again.

[0048] It is readily understood that those skilled in the art can combine, split, or reorganize the embodiments provided in this application to obtain other embodiments, all of which do not exceed the protection scope of this application.
