Abstract
Description
Technical Field
[0001] This utility model relates to the field of chemical sampling technology, specifically a phosphate solution sampling device. Background Technology
[0002] Phosphates are natural inorganic salt compounds that can be divided into simple phosphates and complex phosphates. Sodium, potassium, and ammonium salts of phosphate, as well as all dihydrogen phosphates, are readily soluble in water, while monohydrogen phosphates and orthophosphates, except for sodium, potassium, and ammonium salts, are generally insoluble in water.
[0003] Before sampling phosphate solutions, ensure that the sampling container is clean and dry. Rinse the container two to three times with a small amount of the solution to be sampled to avoid contamination of the sample by impurities. When sampling, select appropriate tools according to the properties of the solution, such as using a pipette or syringe to measure accurately. If the solution contains precipitate, shake well or filter it before sampling.
[0004] After the phosphate solution is sampled, it needs to be placed inside the sample bottle. Since the phosphate solution is sensitive to temperature, if the temperature of the phosphate solution cannot be kept constant inside the sample bottle, its concentration and chemical form will change with temperature fluctuations, resulting in measurement errors or sample deterioration.
[0005] Therefore, a phosphate solution sampling device is proposed to address the above problems. Utility Model Content

[0023] 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 scope of protection of the present utility model.
[0024] Specific implementation examples are given below.
[0025] like Figures 1 to 5As shown in the embodiment of this utility model, a phosphate solution sampling device includes a constant temperature chamber 1, with a sealing cover 11 on the side wall of the constant temperature chamber 1; a temperature sensor 12 is fixedly connected to the side wall of the constant temperature chamber 1; a support rod 15 is fixedly connected to the bottom inner side of the constant temperature chamber 1; a circulation pipe 13 is fixedly connected to the top of the support rod 15; a water inlet 14 is fixedly connected to the top of the circulation pipe 13; a water outlet 16 is fixedly connected to the bottom of the circulation pipe 13; an electric push rod 17 is fixedly connected to the bottom inner side of the constant temperature chamber 1; a pressure plate 18 is fixedly connected to the top of the electric push rod 17; and multiple placement slots 19 are provided on the bottom inner side of the constant temperature chamber 1. After the phosphate solution is placed into the sampling bottle, hot water can be injected into the water inlet 14. After the hot water is injected, it will begin to circulate inside the circulation pipe 13. During the circulation, the hot water will transfer heat to the surface of the circulation pipe 13. At this time, the sampling bottle can be placed in the placement slot 19. Inside, the placement slot 19 then limits the sampling bottle, and the electric actuator 17 can be activated. The electric actuator 17 will drive the pressure plate 18 to extend and retract. When the pressure plate 18 contacts the sampling bottle cap, the electric actuator 17 stops. At this time, the sampling bottle placed inside the placement slot 19 will be limited by the pressure plate 18. At this time, the amount of hot water injected into the circulation pipe 13 can be selected according to the temperature inside the constant temperature chamber 1 displayed on the temperature sensor 12. The hot water will eventually flow out of the constant temperature chamber 1 through the outlet 16. After the temperature inside the constant temperature chamber 1 reaches a constant temperature, the sealing cap 11 can be placed on the constant temperature chamber 1. By adding the circulation pipe 13, the sampling bottle can be kept at a constant temperature inside the constant temperature chamber 1, reducing the temperature fluctuation of the phosphate solution inside the sampling bottle, which may lead to measurement errors in the phosphate solution, and further improving the integrity of the phosphate solution after sampling.
[0026] like Figures 2 to 4 As shown, a circular hole 22 is provided at the bottom inner side of the constant temperature chamber 1; multiple heat dissipation holes 21 are provided at the bottom of the constant temperature chamber 1; a thermal expansion rod 2 is fixedly connected inside the circular hole 22; a cover plate 23 is fixedly connected to the top of the thermal expansion rod 2; when the internal temperature of the constant temperature chamber 1 is too high, the thermal expansion rod 2 will begin to expand and contract due to the high internal temperature of the constant temperature chamber 1. When the thermal expansion rod 2 expands and contracts, it will push up the cover plate 23, and then air will enter the constant temperature chamber 1 from the outside through the heat dissipation holes 21, which can cool down the inside of the constant temperature chamber 1; by adding the thermal expansion rod 2, the internal temperature of the constant temperature chamber 1 can be cooled down in time when it is too high, reducing the possibility of the phosphate solution deteriorating due to excessively high internal temperature. The thermal expansion rod 2 can keep the inside of the constant temperature chamber 1 at a constant temperature.
[0027] like Figures 2 to 3As shown, a support base 31 is fixed to the inner wall of the constant temperature chamber 1; a telescopic insulation cloth 3 is provided inside the support base 31; a push plate 32 is connected to the end of the telescopic insulation cloth 3; after the temperature inside the constant temperature chamber 1 is suitable, the push plate 32 can be pulled, and then the push plate 32 will drive the telescopic insulation cloth 3 to be pulled out from inside the support base 31, and the telescopic insulation cloth 3 will expand and contract. At this time, the push plate 32 can be pulled to the side wall of the constant temperature chamber 1, thereby fully opening the telescopic insulation cloth 3; by adding the telescopic insulation cloth 3, the temperature inside the constant temperature chamber 1 can be maintained after it becomes constant, and the telescopic insulation cloth 3 can reduce the diffusion of heat and improve the long-term maintenance of temperature inside the constant temperature chamber 1.
[0028] like Figures 2 to 3 As shown, a spring 4 is fixedly connected inside the placement groove 19; a base plate 41 is fixedly connected to the top of the spring 4; when the phosphate solution sampling bottle is placed inside the placement groove 19, the sampling bottle will first contact the base plate 41, and then the base plate 41 will extend and retract. When it is necessary to lift and move the constant temperature chamber 1, the base plate 41 will buffer the phosphate solution sample bottle; by adding the spring 4, the phosphate solution can be buffered when placed inside the placement groove 19, reducing the occurrence of shaking or even breakage of the sample bottle due to external forces inside the placement groove 19.
[0029] like Figure 4 As shown, the inner wall of the constant temperature chamber 1 is provided with a sliding groove 51; a support plate 52 is provided inside the sliding groove 51; the support plate 52 is slidably connected inside the sliding groove 51; a motor 53 is fixedly connected to the top of the support plate 52; a cooling fan 5 is fixedly connected to the output end of the motor 53; after the phosphate solution sample bottle is taken out of the placement slot 19 for use, the sealing cap 11 can be opened, and then the motor 53 can be started. The motor 53 will drive the cooling fan 5 to start rotating, and the cooling fan 5 will quickly cool down the inside of the constant temperature chamber 1; by adding the cooling fan 5, the sample bottle inside the constant temperature chamber 1 can be quickly cooled down after use, which facilitates the continued storage of the phosphate solution sample bottle next time.
[0030] like Figure 5 As shown, a rubber pad 6 is fixed to the bottom of the pressure plate 18; the rubber pad 6 and the pressure plate 18 are correspondingly arranged; when the pressure plate 18 contacts the cap of the phosphate solution sample bottle, the rubber pad 6 will preferentially contact the phosphate solution sample bottle, and the rubber pad 6 can increase the contact area with the phosphate solution sample bottle; by adding the rubber pad 6, the phosphate solution sample bottle can be reduced from being restricted by the pressure plate 18 for a long time, thereby reducing the possibility of damage to the cap of the phosphate solution sample bottle.
[0031] Working principle: After placing the phosphate solution into the sampling bottle, hot water can be injected into the water inlet 14. After the hot water is injected, it will circulate in the circulation pipe 13. During the circulation, the hot water will transfer heat to the surface of the circulation pipe 13. At this time, the sampling bottle can be placed into the placement tank 19. The placement tank 19 will then limit the sampling bottle. At the same time, the electric actuator 17 can be activated. The electric actuator 17 will drive the pressure plate 18 to extend and retract up and down. When the pressure plate 18 contacts the cap of the sampling bottle, the electric actuator 17 is stopped, and the bottle is placed in the placement tank 19. The sampling bottle inside is limited by the pressure plate 18. At this time, the amount of hot water injected into the circulation pipe 13 can be selected according to the temperature inside the constant temperature chamber 1 displayed on the temperature sensor 12. The hot water will eventually flow out of the constant temperature chamber 1 through the outlet 16. After the temperature inside the constant temperature chamber 1 reaches a constant temperature, the sealing cover 11 can be placed on the constant temperature chamber 1. When the temperature inside the constant temperature chamber 1 is too high, the thermal expansion rod 2 will start to expand and contract due to the high temperature inside the constant temperature chamber 1. When the thermal expansion rod 2 expands and contracts, it will push up the cover plate 23. Subsequently, air enters the constant temperature chamber 1 from the outside through the heat dissipation hole 21, cooling the interior of the chamber. Once the interior temperature is suitable, the push plate 32 can be pulled, causing the telescopic insulation cloth 3 to extend from the support base 31. The telescopic insulation cloth 3 then extends and retracts. The push plate 32 can then be pulled to the side wall of the constant temperature chamber 1, fully opening the telescopic insulation cloth 3. When the phosphate solution sampling bottle is placed into the placement slot 19, the sampling bottle will first contact the bottom plate 41, after which the bottom plate 41 will extend and retract. When the constant temperature chamber 1 needs to be lifted and moved, the base plate 41 will act as a buffer for the phosphate solution sample bottle. After the phosphate solution sample bottle is taken out of the placement slot 19 for use, the sealing cap 11 can be opened, and then the motor 53 can be started. The motor 53 will drive the cooling fan 5 to start rotating. At this time, the cooling fan 5 will quickly cool down the inside of the constant temperature chamber 1. When the pressure plate 18 contacts the cap of the phosphate solution sample bottle, the rubber pad 6 will first contact the phosphate solution sample bottle. The rubber pad 6 can increase the contact area with the phosphate solution sample bottle.
