Description

Technical Field

[0001] The invention belongs to the field of natural science experiments, and in particular relates to an experimental device for studying the attenuation law of sodium hypochlorite. Background Art

[0002] During the operation of the water supply network, sodium hypochlorite needs to be added to specific places to disinfect the tap water. Since the concentration of free chlorine produced by the hydrolysis of sodium hypochlorite will decay over time, the chlorate produced by the disproportionation reaction will gradually increase over time, the disinfection effect will be greatly reduced and there will be water quality risks. The decomposition and disproportionation rates of sodium hypochlorite are affected by the storage temperature.

[0003] Prior art includes an invention named "Sodium Hypochlorite Concentration Detector", the patent number of which is US9435760B2. This invention designs a detector for detecting the concentration of sodium hypochlorite, including a first electrode, a second electrode and a processing unit. The first electrode and the second electrode are arranged opposite to each other and immersed in the detected sodium hypochlorite solution. An electrical path is formed between the first electrode, the sodium hypochlorite solution and the second electrode. The processing unit is electrically connected to the first electrode and the second electrode, measures multiple ions in the sodium hypochlorite solution transmitted in the electrical path to obtain the conductivity of the sodium hypochlorite solution, and calculates the concentration of the sodium hypochlorite solution accordingly. This invention not only has a low production cost, but also can immediately obtain the measured concentration without the need for analysis by an external computer. However, this invention cannot achieve the decomposition and disproportionation rates of sodium hypochlorite at various ambient temperatures. Summary of the invention

[0004] The invention aims to provide an experimental device for studying the attenuation law of sodium hypochlorite with stable ambient temperature and adjustable multiple temperatures.

[0005] The technical solution adopted by the present invention to achieve the above-mentioned purpose is:

[0006] An experimental device for studying the attenuation law of sodium hypochlorite comprises a water bath body, a sodium hypochlorite box is arranged in the water bath body, a plurality of electric heating elements are arranged in the water bath body, a heat exchange tank is arranged on one side of the water bath body, a heat exchange component is arranged in the heat exchange tank, and the heat exchange component is used for regulating the temperature in the water bath body.

[0007] The present invention can heat the liquid in the water bath body on demand through the multiple electric heating elements in the water bath body through the overall design of an experimental device for studying the attenuation law of sodium hypochlorite, that is, adjust the temperature of the water body inside the water bath body according to the required experimental temperature, strictly control the experimental conditions, and ensure the reliability of the experimental results. The setting of the heat exchange tank and the heat exchange component can realize the input and / or output of the water body inside the water bath body, and the heat exchange tank can realize rapid heat exchange of the water body inside it, resulting in a temperature difference between the water bath body and the water body inside the heat exchange tank, and then achieve the effect of quickly adjusting the water temperature by mixing water bodies of different temperatures; in this process, by controlling the flow rate and flow rate of the water body, the water temperature can be accurately controlled.

[0008] In addition, by setting up a water exchange tank, the flow of water inside the water bath tank is achieved, which helps to improve the thermal balance of the sodium hypochlorite box and reduce the temperature difference between various positions in the sodium hypochlorite box during the experiment, thereby improving the reliability of the experimental results.

[0009] Furthermore, a temperature sensor is provided in the water bath body, through which real-time temperature monitoring of the water body inside the water bath body can be achieved, and then the temperature sensor can be used to provide feedback to the electric heating element. When it is detected that the water temperature exceeds the preset temperature, the power supply to the electric heating element is stopped, that is, the heating of the water body in the water bath body is stopped; when it is detected that the water temperature is lower than the preset temperature, the power supply to the electric heating element can be continued, that is, the water body in the water bath body can be continued to be heated, so that the water temperature is raised to the preset temperature, thereby ensuring the accuracy of the experimental conditions.

[0010] According to an embodiment of the present invention, the heat exchange component is connected to the water bath body through a connecting pipe; a pump body is provided on the connecting pipe.

[0011] According to an embodiment of the present invention, the connecting pipe includes an inlet pipe and an outlet pipe, and the pump body is arranged on the inlet pipe or the outlet pipe; the inlet pipe and the outlet pipe are used to form a closed loop structure between the heat exchange component and the water bath tank body.

[0012] Through the above design, the flow rate and flow rate of water exchange between the water bath body and the heat exchange tank can be controlled in real time according to experimental needs by using the cooperation of the pump body and the connecting pipe, thereby adjusting the water temperature inside the water bath body and ensuring the water mixing effect.

[0013] In addition, the pump body is started according to the experimental needs. If the experimental purpose does not require the constancy of the water temperature inside the water bath body, there is no need to start the pump body.

[0014] According to an embodiment of the present invention, the heat exchange assembly includes a hollow heat exchange base, a rotating shaft is coaxially arranged in the heat exchange base, a plurality of barrier floating plates are arranged on the rotating shaft at intervals, and a plurality of rotating plates are arranged in parallel between adjacent barrier floating plates.

[0015] According to an embodiment of the present invention, one side of the rotating shaft extends through the heat exchange component, and a fan is disposed at the end of the rotating shaft.

[0016] In this way, when the water from the water bath body enters the heat exchange matrix through the inlet pipe, it impacts the heat exchange matrix, thereby prompting the barrier float and the rotating plate to rotate inside the heat exchange matrix, thereby driving the water near them to operate to form a vortex, thereby increasing the contact probability between the water and the inner wall of the heat exchange matrix, which helps to improve the heat exchange effect of the water, especially helps to achieve rapid heat dissipation and rapid cooling of the water; in addition, the impact of the water can be absorbed by the barrier float and the rotating plate, and when the water flows out of the heat exchange matrix from the outlet pipe, it ensures that the water flow rate is stable and there is no turbulence inside, thereby preventing the formation of large turbulence when the water enters the water bath body, causing the water to shake.

[0017] In addition, the heat exchange component cooperates with the fan. When the water drives the heat exchange matrix to rotate, the rotating shaft drives the fan to rotate synchronously, thereby causing the flow of gas near the heat exchange groove. The airflow can take away the heat from the surface of the heat exchange matrix, which helps to improve the heat exchange effect and enhance the regulation effect of the water temperature inside the heat exchange matrix.

[0018] The cooperation of the barrier float and the rotating plate helps to improve the swirl effect of the water body; the two are set vertically, which can block the water body from different angles and realize the diversion and mixing of local water bodies. In addition, the barrier float and the rotating plate can also drive part of the water body to turn synchronously with them during the rotation process, thereby increasing the contact probability between the water body and the inner wall of the heat exchange matrix.

[0019] According to one embodiment of the present invention, a plurality of electric heating elements are arranged in parallel and at intervals on the bottom side of the water bath body, a plurality of guide components are arranged between adjacent electric heating elements, the top side of the guide component is arranged higher than the electric heating element, and the top side of the guide component abuts the bottom side of the sodium hypochlorite box.

[0020] The top of the flow guide component supports the sodium hypochlorite tank. Through the above design, the flow guide component is used to separate the sodium hypochlorite tank from the electric heating element, so that a certain distance is formed between the two, thereby avoiding overheating of the bottom of the sodium hypochlorite tank, that is, causing uneven temperature inside the sodium hypochlorite tank. In addition, the flow guide component has a guiding effect on the water at the bottom of the water bath tank, and can guide the lateral flow of the bottom water body, thereby avoiding the overheated water at the bottom of the water bath tank heated by the electric heating element directly impacting the bottom of the sodium hypochlorite tank, and achieving uniform heating of the sodium hypochlorite tank.

[0021] According to one embodiment of the present invention, the guide assembly includes a rotating shaft, and a plurality of fan blades and vertical plates are arranged around the outer side of the rotating shaft, and the fan blades and the vertical plates are arranged at staggered heights; the bottom side of the rotating shaft is rotatably connected to the bottom side of the water bath body through a first bearing, and a support plate is arranged on the top side of the rotating shaft, and the top side of the rotating shaft is rotatably connected to the support plate through a second bearing, and the support plate is used to abut the bottom side of the sodium hypochlorite box.

[0022] Furthermore, the support plate is fixedly connected to the bottom of the sodium hypochlorite box.

[0023] The above technical solution is adopted to realize effective spacing control between the sodium hypochlorite box and the water bath body, and to avoid uneven heating of the sodium hypochlorite box due to uneven upper and lower temperatures inside the water bath body. The rotating shaft in the diversion component drives the fan blades and the vertical plates to rotate, thereby causing the superheated water attached to the electric heating element to disperse, which can prevent the bottom water from being too concentrated and reduce the probability of the bottom superheated water directly exchanging heat with the bottom of the sodium hypochlorite box. In this process, the diversion effect of the diversion component can reduce the impact of the bottom water on the bottom of the sodium hypochlorite box, thereby improving the stability of the sodium hypochlorite box and ensuring the smooth progress of the experiment; and the fan blades and the vertical plates rotate with the rotating shaft to promote the flow of water, which helps to promote the temperature of the upper and lower layers of water to tend to balance.

[0024] In addition, when the water inside the water bath body is input and / or output through the cooperation of the pump body and the connecting pipe, some fast-flowing water can affect the rotation of the fan blades and vertical plates on the guide assembly at the bottom of the water bath body, increase the rotation speed, and thus help the flow of water at the bottom of the water bath body. In addition, the cooperation of the guide assembly and the heat exchange assembly can accelerate the mixing of the water inside the heat exchange tank and the water inside the water bath body, thereby helping to make the water temperature tend to be balanced, and the water inside the water bath body (especially the bottom) is neutralized by the water with a lower temperature from the inside of the heat exchange tank, thereby avoiding excessive water temperature and ensuring the stability of the experimental temperature.

[0025] According to an embodiment of the present invention, a plurality of auxiliary parts are provided on the inner wall of the water bath body. The auxiliary parts include a first rod body and a second rod body arranged crosswise, and the first rod body and the second rod body are rotatably connected.

[0026] Furthermore, an extension mesh plate is provided on the first rod body or the second rod body, and the extension mesh plate is arranged perpendicular to the inner wall of the water bath body where the auxiliary part is located.

[0027] Through the above scheme, the water inside the water bath body flows under the influence of the heat exchange component and the guide component, which will affect the state of the auxiliary parts. One rod body is rotatably connected to the second rod body, so under the action of the flowing water body, the two swing alternately, thereby prompting the extended mesh plate to swing. In this way, the fluidity of the water body near the side of the water bath body can be improved, thereby promoting the mixing between the middle water body and the peripheral water body in the water bath body, and improving the balance of water temperature. On the other hand, the setting of the auxiliary parts, especially the swingable extended mesh plate, can be used to intercept the flowing water body, thereby reducing the impact of the water body on the sodium hypochlorite tank, avoiding uneven force on the sodium hypochlorite tank during the water exchange between the water bath body and the heat exchange tank, thereby improving stability, avoiding high-frequency displacement, shaking or flipping of the sodium hypochlorite tank, etc., causing the solution in the sodium hypochlorite tank to shake and cause inaccurate experimental tests.

[0028] Furthermore, the plurality of first rods and the plurality of second rods are arranged alternately in a stepped shape, so that the working space of the auxiliary component can be expanded.

[0029] According to one embodiment of the present invention, a cover is provided on the upper part of the water bath body, a pressure relief member is provided on the cover, and an insulation layer is provided on the outer wall of the water bath body. The cover and the insulation layer can prevent the temperature of the water inside the water bath body from being lost, thereby saving energy.

[0030] Furthermore, a sealing ring is arranged between the lower surface of the cover body and the top surface of the water bath body.

[0031] Furthermore, the cover body is provided with a pressure relief through hole, and the pressure relief member can be movably embedded in the interior of the pressure relief through hole.

[0032] Therefore, the pressure relief part can be used to regulate the air pressure inside the water bath, avoiding excessive air pressure caused by evaporation of water, etc., and ensuring the stability of experimental conditions. When the heating element heats the water bath, some of the gas remaining in the water will escape, and the overflowing gas will increase the internal pressure. By regulating the internal pressure through the pressure relief part and reducing the gas content in the water, the purity of the water can be improved, and then the thermal conductivity of the water can be improved to ensure the efficiency of the water in receiving heat and exchanging heat.

DETAILED DESCRIPTION

[0047] The technical solution of the present invention is further described in detail below in conjunction with specific implementations and drawings:

[0048] Embodiment 1:

[0049] like Figure 1-Figure 10 As shown, an experimental device for studying the attenuation law of sodium hypochlorite includes a water bath body 1, a sodium hypochlorite box 2 is arranged in the water bath body 1, a plurality of electric heating elements 11 are arranged in the water bath body 1, a heat exchange tank 12 is arranged on one side of the water bath body 1, a heat exchange component 3 is arranged in the heat exchange tank 12, and the heat exchange component 3 is used to control the temperature in the water bath body 1.

[0050] The present invention can heat the liquid in the water bath body 1 on demand through the multiple electric heating elements 11 in the water bath body 1, that is, adjust the temperature of the water inside the water bath body 1 according to the required experimental temperature, strictly control the experimental conditions, and ensure the reliability of the experimental results through the overall design of an experimental device for studying the attenuation law of sodium hypochlorite. The heat exchange tank 12 and the heat exchange component 3 are arranged to input and / or output the water inside the water bath body 1, and the heat exchange tank 12 can realize rapid heat exchange of the water inside it, resulting in a temperature difference between the water bath body 1 and the water inside the heat exchange tank 12, and then the water temperature is quickly adjusted by mixing water bodies of different temperatures; in this process, the water temperature can be accurately controlled by controlling the flow rate and flow rate of the water body.

[0051] In addition, by setting up the water exchange tank, the flow of water inside the water bath tank body 1 is achieved, which helps to improve the thermal balance of the sodium hypochlorite box 2 and reduce the temperature difference between various positions of the upper, lower, left and right inside the sodium hypochlorite box 2 during the experiment, thereby improving the reliability of the experimental results.

[0052] Furthermore, a temperature sensor is provided in the water bath body 1, and real-time temperature monitoring of the water body inside the water bath body 1 can be achieved through the temperature sensor. Then, the temperature sensor can be used to provide feedback to the electric heating element 11. When it is detected that the water temperature exceeds a preset temperature, the power supply to the electric heating element 11 is stopped, that is, the heating of the water body in the water bath body 1 is stopped; when it is detected that the water temperature is lower than a preset temperature, the power supply to the electric heating element 11 can be continued, that is, the water body in the water bath body 1 can be continued to be heated, so that the water temperature is raised to the preset temperature, thereby ensuring the accuracy of the experimental conditions.

[0053] The heat exchange assembly 3 is connected to the water bath body 1 through a connecting pipe; a pump body 15 is provided on the connecting pipe.

[0054] The connecting pipe includes an inlet pipe 13 and an outlet pipe 14 , and a pump body 15 is arranged on the inlet pipe 13 or the outlet pipe 14 ; the inlet pipe 13 and the outlet pipe 14 are used to form a closed loop structure between the heat exchange component 3 and the water bath tank body 1 .

[0055] Through the above design, the pump body 15 and the connecting pipe can be used to control the flow rate and flow rate of water exchange between the water bath body 1 and the heat exchange tank 12 in real time according to experimental needs, thereby adjusting the water temperature inside the water bath body 1 and ensuring the water mixing effect.

[0056] In addition, the pump body 15 is started according to the experimental needs. If the experimental purpose does not require the constancy of the water temperature inside the water bath tank body 1, the pump body 15 does not need to be started.

[0057] The heat exchange assembly 3 includes a hollow heat exchange base 31 , in which a rotating shaft 32 is coaxially arranged, a plurality of barrier floating plates 33 are arranged at intervals on the rotating shaft 32 , and a plurality of rotating plates 34 are arranged in parallel between adjacent barrier floating plates 33 .

[0058] One side of the rotating shaft 32 extends through the heat exchange assembly 3 , and a fan 35 is disposed at the end of the rotating shaft 32 .

[0059] In this way, when the water from the water bath tank body 1 enters the heat exchange matrix 31 through the inlet pipe 13, it impacts the heat exchange matrix 31, thereby prompting the barrier float 33 and the rotating plate 34 to rotate inside the heat exchange matrix 31, thereby driving the water near them to operate to form a vortex, thereby increasing the contact probability between the water and the inner wall of the heat exchange matrix 31, which helps to improve the heat exchange effect of the water, especially helps to achieve rapid heat dissipation and rapid cooling of the water; in addition, the impact of the water can be absorbed by the barrier float 33 and the rotating plate 34, and when the water flows out of the heat exchange matrix 31 from the outlet pipe 14, it ensures that the water flow rate is stable and there is no turbulence inside, thereby preventing the water from forming a large turbulence when entering the water bath tank body 1, causing the water to shake.

[0060] In addition, the heat exchange component 3 cooperates with the fan 35. When the water drives the heat exchange base 31 to rotate, the rotating shaft 32 drives the fan 35 to rotate synchronously, thereby causing the flow of gas near the heat exchange groove 12. The airflow can take away the heat from the surface of the heat exchange base 31, which helps to improve the heat exchange effect and enhance the effect of regulating the water temperature inside the heat exchange base 31.

[0061] The cooperation between the barrier float 33 and the rotating plate 34 helps to improve the swirl effect of the water body; the two are arranged vertically, and can block the water body from different angles to achieve the diversion and mixing of the local water body. In addition, the barrier float 33 and the rotating plate 34 can also drive part of the water body to turn synchronously with them during the rotation process, thereby increasing the contact probability between the water body and the inner wall of the heat exchange substrate 31.

[0062] A plurality of electric heating elements 11 are arranged in parallel and at intervals on the bottom side of the water bath body 1 , a plurality of guide components 4 are arranged between adjacent electric heating elements 11 , the top side of the guide component 4 is arranged higher than the electric heating element 11 , and the top side of the guide component 4 abuts against the bottom side of the sodium hypochlorite tank 2 .

[0063] The top of the flow guide component 4 supports the sodium hypochlorite tank 2. Through the above design, the flow guide component 4 is used to separate the sodium hypochlorite tank 2 from the electric heating element 11, so that a certain distance is formed between the two, thereby avoiding overheating of the bottom of the sodium hypochlorite tank 2, that is, causing uneven temperature inside the chlorine acid tank. In addition, the flow guide component 4 has a guiding effect on the water body at the bottom of the water bath tank 1, and can guide the lateral flow of the bottom water body, thereby avoiding the overheated water heated by the electric heating element 11 at the bottom of the water bath tank 1 directly impacting the bottom of the sodium hypochlorite tank 2, and achieving uniform heating of the sodium hypochlorite tank 2.

[0064] The flow guide component 4 includes a rotating shaft 41, and a plurality of fan blades 42 and vertical plates 43 are arranged around the outer side of the rotating shaft 41, and the fan blades 42 and the vertical plates 43 are arranged at staggered heights; the bottom side of the rotating shaft 41 is rotatably connected to the bottom side of the water bath tank body 1 through a first bearing 44, and a support plate 45 is arranged on the top side of the rotating shaft 41, and the top side of the rotating shaft 41 is rotatably connected to the support plate 45 through a second bearing, and the support plate 45 is used to abut the bottom side of the sodium hypochlorite tank 2.

[0065] Furthermore, the support plate 45 is fixedly connected to the bottom of the sodium hypochlorite tank 2 .

[0066] By adopting the above technical solution, effective spacing control between the sodium hypochlorite tank 2 and the water bath body 1 is achieved, and uneven heating of the sodium hypochlorite tank 2 caused by uneven temperatures in the upper and lower parts of the water bath body 1 is avoided. The rotating shaft 41 in the flow guide component 4 drives the fan blades 42 and the vertical plate 43 to rotate, thereby causing the superheated water body attached to the electric heating element 11 to disperse, which can prevent the bottom water body from being too concentrated and reduce the probability of the bottom superheated water body directly exchanging heat with the bottom of the sodium hypochlorite tank 2. In this process, the diversion effect of the flow guide component 4 can reduce the impact of the bottom water body on the bottom of the sodium hypochlorite tank 2, thereby improving the stability of the sodium hypochlorite tank 2 and ensuring the smooth progress of the experiment; and the fan blades 42 and the vertical plate 43 rotate with the rotating shaft 41 to promote the flow of water, which helps to promote the temperature of the upper and lower layers of water to tend to be balanced.

[0067] In addition, during the process of inputting and / or outputting the water inside the water bath body 1 through the cooperation of the pump body 15 and the connecting pipe, some of the fast-flowing water can affect the rotation of the fan blades 42 and the vertical plate 43 on the guide assembly 4 at the bottom of the water bath body 1, increase the rotation speed, and thus help the flow of the water at the bottom of the water bath body 1. In addition, the cooperation of the guide assembly 4 and the heat exchange assembly 3 can accelerate the mixing of the water inside the heat exchange tank 12 and the water inside the water bath body 1, thereby helping to make the water temperature tend to be balanced, and the water inside the water bath body 1 (especially the bottom) is neutralized by the water with a lower temperature from the inside of the heat exchange tank 12, thereby avoiding excessive water temperature and ensuring the stability of the experimental temperature.

[0068] Embodiment 2:

[0069] like Figure 2 and Fig.11 As shown, an experimental device for studying the attenuation law of sodium hypochlorite according to another embodiment of the present invention is different from Example 1 in that a plurality of auxiliary parts 5 are provided on the inner wall of the water bath body 1, and the auxiliary parts 5 include a first rod body 51 and a second rod body 52 arranged crosswise, and the first rod body 51 and the second rod body 52 are rotatably connected.

[0070] Furthermore, an extended mesh plate 53 is provided on the first rod body 51 or the second rod body 52 , and the extended mesh plate 53 is arranged perpendicular to the inner wall of the water bath body 1 where the auxiliary component 5 is located.

[0071] Through the above scheme, the water inside the water bath body 1 flows under the influence of the heat exchange component 3 and the guide component 4, which will affect the state of the auxiliary component 5. The first rod body is rotatably connected to the second rod body 52, so under the action of the flowing water body, the two swing alternately, thereby prompting the extended mesh plate 53 to swing. In this way, the fluidity of the water body near the side of the water bath body 1 can be improved, thereby promoting the mixing between the middle water body and the peripheral water body in the water bath body 1, and improving the water temperature balance. On the other hand, the setting of the auxiliary component 5, especially the swingable extended mesh plate 53, can be used to intercept the flowing water body, thereby reducing the impact of the water body on the sodium hypochlorite tank 2, avoiding uneven force on the sodium hypochlorite tank 2 during the water exchange between the water bath body 1 and the heat exchange tank 12, thereby improving stability, avoiding high-frequency displacement, shaking or flipping of the sodium hypochlorite tank 2, etc., causing the solution in the sodium hypochlorite tank 2 to shake and cause inaccurate experimental tests.

[0072] Furthermore, the plurality of first rods 51 and the plurality of second rods 52 are alternately arranged in a stepped shape, so that the working space of the auxiliary component 5 can be expanded.

[0073] Embodiment 3:

[0074] like Fig.12 and Fig.13 As shown, an experimental device for studying the attenuation law of sodium hypochlorite according to another embodiment of the present invention is different from Example 1 in that a cover 6 is provided on the upper part of the water bath body 1, a pressure relief member 61 is provided on the cover 6, and an insulation layer 62 is provided on the outer wall of the water bath body 1. The arrangement of the cover 6 and the insulation layer 62 can prevent the temperature of the water inside the water bath body 1 from being lost, thereby saving energy.

[0075] Furthermore, a sealing ring is arranged between the lower surface of the cover body 6 and the top surface of the water bath body 1 .

[0076] Furthermore, the cover body 6 is provided with a pressure relief through hole, and the pressure relief member 61 is movably embedded in the pressure relief through hole.

[0077] Thus, the air pressure inside the water bath body 1 can be regulated by the pressure relief member 61 to avoid excessive air pressure caused by evaporation of water, etc., and ensure the stability of the experimental conditions. When the heating element heats the water bath body 1, some of the gas remaining in the water will escape, and the overflowing gas will increase the internal pressure. By regulating the internal pressure through the pressure relief member 61 and reducing the gas content of the water, the purity of the water can be improved, and then the thermal conductivity of the water can be improved to ensure the efficiency of the water in receiving heat and exchanging heat.
