Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example: Figure 1-4 As shown, this utility model provides an automatic filtration device, including a housing 1. A door 11 is hinged to one side of the housing 1. A waste liquid collection tank 12 is installed on the bottom wall of the housing 1. By setting up the waste liquid collection tank 12, the waste liquid generated after filtration and the waste liquid generated during cleaning can be collected in the waste liquid collection tank 12. A waste discharge pipe 13 is installed at the bottom of the waste liquid collection tank 12. A third control valve 14 is installed on the waste discharge pipe 13. An actuator is installed on the third control valve 14. The third control valve 14 is a V-type ball valve, which can allow impurities to pass through. By setting up the waste discharge pipe 13 and the third control valve 14, the third control valve 14 can control the opening and closing of the waste discharge pipe 13. The waste liquid in the waste liquid collection tank 12 can be discharged through the waste discharge pipe 13. A filter assembly 2 and a cleaning assembly 4 are respectively provided on the housing 1. By setting up the filter assembly 2, the filter assembly 2 can filter the treated pyrophosphate. The cleaning assembly 4 can clean the filter assembly 2.

[0027] Filter assembly 2 includes heating cylinders 21 and funnels 23. The heating cylinders 21 are electrically heated. Six heating cylinders 21 and six funnels 23 are arranged in a ring array on the equipment housing 1. The six funnels 23 are detachably installed inside the equipment housing 1 by bolts. The detachability of the funnels 23 allows operators to easily remove the entire funnel 23, thus extracting the pyrophosphate inside. The six funnels 23 are positioned below the six heating cylinders 21, and the inner walls of each heating cylinder 21 are fitted with sample containers. The inner walls of tube 22 and six funnels 23 are all equipped with filter screens 26. By setting up six heating cylinders 21, six sample tubes 22 and six funnels 23, six pyrophosphate sample filtration stations can be provided. When the pyrophosphate sample to be filtered is added into the sample tube 22, the heating cylinder 21 heats the pyrophosphate sample in the sample tube 22 by electric heating and boils it. By setting the filter screen 26 in the funnel 23, when the boiled pyrophosphate sample enters the funnel 23, it is filtered by the filter screen 26.

[0028] Each of the six heating cylinders 21 is equipped with a liquid guide tube 24 at its bottom. One end of the liquid guide tube 24 is connected to the inner cavity of the sample tube 22, and the other end of the liquid guide tube 24 is located above the funnel 23. Each of the six liquid guide tubes 24 is equipped with a first control valve 25, which is equipped with an actuator. The first control valve 25 is a V-type ball valve that can allow impurities to pass through. By setting up the liquid guide tubes 24 and the first control valve 25, the first control valve 25 can control the opening and closing of the liquid guide tubes 24. When the liquid guide tube 24 is in the open state, the pyrophosphate sample in the sample tube 22 can enter the funnel 23 through the liquid guide tube 24.

[0029] The inner wall of the equipment housing 1 is equipped with a collection tank 27, which is located below the six funnels 23. A detection sensor 28 is installed on one side of the collection tank 27. The detection sensor 28 is a phosphate detection sensor. The probe of the detection sensor 28 is connected to the inner cavity of the collection tank 27. By setting up the collection tank 27 and the detection sensor 28, the liquid filtered by the funnels 23 can flow into the collection tank 27 (including the liquid generated during the cleaning operation). The detection sensor 28 can detect the liquid in the collection tank 27 to detect whether the liquid contains phosphate and display the data results on its display screen.

[0030] The bottom of the collection tank 27 is equipped with a connecting pipe 29. One end of the connecting pipe 29 is connected to the inner cavity of the waste liquid collection tank 12. A second control valve 3 is installed on the connecting pipe 29. An actuator is installed on the second control valve 3. The second control valve 3 is a V-type ball valve that can allow impurities to pass through. By setting the connecting pipe 29 and the second control valve 3, the second control valve 3 can control the opening and closing of the connecting pipe 29. The liquid in the collection tank 27 can enter the waste liquid collection tank 12 through the connecting pipe 29.

[0031] The cleaning assembly 4 includes a heating tank 41, which is mounted on the equipment housing 1. The heating tank 41 is electrically heated. An inner tank 42 is installed inside the heating tank 41 to store cleaning water. The heating tank 41 heats and boils the cleaning water in the inner tank 42 using electric heating. A filling pipe 421 is installed at the top of the heating tank 41 to facilitate the addition of cleaning water to the inner tank 42 by operators. A liquid pump 43 is mounted on the upper surface of the equipment housing 1. A liquid extraction pipe 44 is installed at the inlet of the liquid pump 43, and one end of the liquid extraction pipe 44 is connected to the inner cavity of the inner tank 42. The outlet of the pump 43 is equipped with a drain pipe 45, and the upper surface of the equipment housing 1 is equipped with a diversion pipe 46. One end of the drain pipe 45 is connected to one end of the diversion pipe 46. The diversion pipe 46 is equipped with six branch pipes 47 arranged in a ring array. One end of each of the six branch pipes 47 is equipped with a nozzle 48. The nozzle 48 is located above the sample tube 22. By starting the pump 43, the pump 43 can draw the cleaning water in the inner tank 42 through the pump pipe 44, and deliver the drawn cleaning water to the nozzle 48 through the drain pipe 45, the diversion pipe 46 and the branch pipes 47. The cleaning water is sprayed into the sample tube 22 from the nozzle 48 to clean the sample tube 22.

[0032] Working principle: When it is necessary to filter the processed pyrophosphate, the operator first transfers the processed and diluted pyrophosphate sample into six sample tubes 22, and heats the pyrophosphate sample in the six sample tubes 22 through six heating cylinders 21 until it boils. At the same time, cleaning water is added into the inner tank 42 through the filling pipe 421, and the cleaning water in the inner tank 42 is heated through the heating tank 41 until it boils.

[0033] Then, the actuators on the six No. 1 control valves 25 are activated to open the six No. 1 control valves 25. The pyrophosphoric acid boiled in the six sample tubes 22 flows into the corresponding funnels 23 through the six liquid guide tubes 24. The filter screens 26 in the six funnels 23 filter the boiled pyrophosphoric acid. The waste liquid generated by filtration enters the waste liquid collection tank 12 through the connecting pipe 29 and is then discharged through the waste discharge pipe 13.

[0034] After the pyrophosphate samples in the six funnels 23 have been filtered, the pump 43 is started. The pump 43 draws the cleaning water from the inner tank 42 through the pump pipe 44. The drawn cleaning water is then transported to the six nozzles 48 through the drain pipe 45, the diversion pipe 46 and the branch pipe 47. The cleaning water is sprayed from the six nozzles 48 into the corresponding sample tubes 22 to clean the six sample tubes 22. The filter screens 26 and residues in the six sample tubes 22 and the six funnels 23 are rinsed and filtered until the detection sensor 28 on the collection tank 27 shows no phosphate ions. The cleaning then stops automatically, and the process is complete.

[0035] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
