Description

[0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] COD (chemical oxygen demand), ammonia nitrogen, total phosphorus and total nitrogen are common pollutant indicators in sewage treatment. In the water treatment process, the detection of the above pollutants in water quality is essential. Under the current circumstances, water samples are generally sucked from the corresponding position and transferred to the liquid level detection container. When the water volume rises and reaches the specified liquid level, the quantitative water sample is transferred to the digestion detection container through the pump body for high-temperature digestion. After the digestion is completed, it is necessary to wait for the water sample to cool down to room temperature. After that, the pump body will absorb the reagent and inject it into the water sample for mixing. The mixed water sample is detected by the detection equipment to detect the color change of the mixed water sample, and then the various indicators of pollutants in the water are detected.

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-7 The present invention discloses a water quality detection device, including a first box body 1 and a second box body 2, the second box body 2 is installed on the first box body 1, the first box body 1 and the second box body 2 are connected up and down, the first box body 1 is filled with cooling water, and a cooling component for dissipating heat from the cooling water is installed on the first box body 1, the cooling component is used to transfer the heat in the cooling water to the outside of the device, and at the same time, the cooling component belongs to the common knowledge in the field, so the specific structure and working principle thereof will not be described in detail in this article.

[0035] In one embodiment, the device also includes a digestion component 6, which can be slid up and down in the first box body 1. The digestion component 6 has two detection chambers 62 distributed on the left and right and independent of each other. The digestion component 6 is used to perform liquid level detection and heating digestion on the water sample in the corresponding detection chamber 62. The first box body 1 is provided with a conveying component 4, which is used to absorb the test water sample or reagent into the corresponding detection chamber 62. The digestion component 6 is provided with a drainage component 7, which is used to discharge the water sample in the corresponding detection chamber 62.

[0036] At the same time, a driving component is also provided on the first box body 1, which is used to drive the digestion component 6 to perform lifting and lowering movements, so that the digestion component 6 moves back and forth between the first box body 1 and the second box body 2. When the digestion component 6 descends to the inside of the first box body 1, it is cooled by the cooling water inside the first box body 1. A detection component 9 is provided in the second box body 2, and the detection component 9 is used to detect the water sample in the digestion component 6. A transmission component 8 is also provided in the first box body 1. The transmission component 8 is used to drive the detection component 9 to move left and right when the driving component controls the digestion component 6 to rise. When the digestion component 6 is located inside the second box body 2, the detection component 9 is used to detect the water sample in the corresponding detection chamber 62.

[0037] In the specific implementation, in the initial state of the device, the digestion component 6 is located in the second box 2. First, the conveying component 4 is controlled to absorb the water sample and transmit it to one of the detection chambers 62 on the digestion component 6. When the digestion component 6 detects that the water level has reached a specified height, the conveying component 4 is controlled to stop delivering water, and then the digestion component 6 is started to heat the digestion component 6 and digest the water sample. After the digestion is completed, the digestion component 6 still has a high temperature. At this time, the driving component drives the digestion component 6 to descend into the first box 1, and the cooling water in the first box 1 is used to cool the digestion component 6. During the process, a second portion of cooling water is injected into another detection chamber 62 on the digestion component 6 through the conveying component 4 in the above manner, and then the digestion component 6 is driven to rise to the first box body 1 through the driving component, and a reagent is injected into one of the detection chambers 62 on the digestion component 6 through the conveying component 4. The color of the reagent changes after mixing with the digested water, and the detection component 9 moves left and right and aligns with the corresponding detection chamber 62 when the digestion component 6 rises to the inside of the second box body 2, thereby detecting the water that has changed color in the corresponding detection chamber 62, so that the index of pollutants in the water can be obtained.

[0038] It should be noted that, after the water sample in one of the detection chambers 62 on the digestion component 6 has been detected, the drainage component 7 is controlled to open to discharge the water sample in the corresponding detection chamber 62. At this time, the digestion component 6 can be controlled to perform high-temperature digestion on the second portion of cooling water in another detection chamber 62, and continue to process in the above manner. The detection equipment does not need to repeatedly transport and process the water samples when testing multiple batches of water samples, and can actively cool the digested water, so it can effectively save unnecessary processing time, thereby improving the detection efficiency, and the above-mentioned equipment can be automatically controlled and remotely monitored by the controller, and the corresponding control and detection methods are common knowledge in the field, so the working principle will not be described in detail in this article.

[0039] In one embodiment, the digestion component 6 includes a processing container 61 with a cylindrical shape, two detection chambers 62 are respectively opened on the left and right sides of the processing container 61, and the processing container 61 also has two unconnected conveying channels 63, the output ends of the two conveying channels 63 are respectively connected to the two detection chambers 62, and the input ends of the two conveying channels 63 are connected to the conveying component 4. A transparent detection window 64 is embedded on the side wall of the processing container 61, and the detection window 64 is used to cooperate with the detection component 9 to detect the water sample in the corresponding detection chamber 62. A liquid level sensor 65 is installed on the processing container 61, and the liquid level sensor 65 is used to detect the liquid level height in the corresponding detection chamber 62. The two corresponding detection chambers 62 of the processing container 61 are both installed with independent heaters 66, and the heater 66 It is used to heat and digest the water sample in the corresponding detection chamber 62. Two liquid outlet holes are set at the bottom of the processing container 61, and the drainage component 7 is a three-way valve. The two liquid outlet holes correspond to the two input ends of the drainage component 7 respectively. The drainage component 7 includes a valve body 71. The valve body 71 has a drain port 73 and two water inlets 72. The two water inlets 72 are respectively connected to the two liquid outlet holes, and each water inlet 72 on the two valve bodies 71 is in a normally closed state. A drainage pipe 11 is installed at the drain port 73. The output end of the drainage pipe 11 is located outside the first box body 1 and the second box body 2, and it is used to guide the detection water to be discharged outside each box body. The two input ends of the drainage component 7 can be in a closed state or an open state. When the corresponding input end is opened, it is used to discharge the liquid in the corresponding detection chamber 62 from the drain port 73.

[0040] In the specific implementation, each drainage port 73 on the drainage component 7 is initially in a closed state, and the staff controls the conveying component 4 to start, which absorbs the water sample and transmits it to the corresponding conveying channel 63. During this process, the water is transmitted to the corresponding detection chamber 62 through the output end of the corresponding conveying channel 63. As the conveying component 4 continues to work and deliver water, the water level in the detection chamber 62 gradually rises, and the liquid level sensor 65 detects the water level. When the height reaches the threshold, the conveying component 4 is controlled to stop, and then the corresponding heater 66 is started to heat the water in the corresponding detection chamber 62 to digest the water at high temperature. Moreover, when the water and the reagent are mixed, the liquid level will reach the detection window 64. Since the detection window 64 is transparent and semi-circular, the detection component 9 can directly detect the water in the detection chamber 62 through the overlapping part of the two arc edges of the detection window 64. This method will not make the light at the detection point too dark and affect the detection accuracy, thereby facilitating actual use.

[0041] It should be noted that after the detection is completed, the corresponding drain port 73 of the drain component 7 is controlled to open so that the water in the corresponding detection chamber 62 can be discharged from the drain port 73 of the drain component 7.

[0042] In one embodiment, the conveying component 4 includes a transmission pump 41 installed on the first box body 1, and the transmission pump 41 has two input ports 42. The two input ports 42 are respectively connected to the detection water sample source and the reagent source through pipelines. The two input ports 42 respectively cooperate to absorb the detection water sample or reagent and transport it to the output end of the transmission pump 41 when the transmission pump 41 is started. A guide component 43 and two one-way valves 44 are installed in the first box body 1. The guide component 43 is a three-way valve, which has two output ends and one input end. Its input end is connected to the output end of the transmission pump 41, and the two output ends of the guide component 43 are respectively connected to the input ends of the two one-way valves 44. The output ends of the two one-way valves 44 are both connected with a hose 45. The other ends of the two hoses 45 away from the one-way valve 44 are respectively connected to the input ends of the two conveying channels 63, so that the detection water sample or reagent enters the corresponding conveying channel 63.

[0043] In a specific implementation, when the transfer pump 41 is started, it cooperates with one of the input ports 42 to absorb water or reagents and transfers them to the guide component 43, and the guide component 43 can select one of the output ends to open through electric control, so that the water or reagent is transferred to the corresponding hose 45. As the delivery continues, the water or reagent will pass through the corresponding delivery channel 63 and be transferred to the detection chamber 62 connected thereto, thereby completing the delivery of the water sample or reagent. The transfer pump 41 with two input ports 42 and the ability to select one of the input ports 42 to absorb liquid is common knowledge in the field, so the specific working principle thereof will not be described in detail in this article.

[0044] In one embodiment, the driving assembly includes a motor 3 installed on the first housing 1, and the moving end of the motor 3 is equipped with a screw 5 extending into the first housing 1 and the second housing 2 in sequence. The screw 5 is dynamically sealed with the first housing 1. The screw 5 is located at the center of the digestion assembly 6 and is threadedly engaged with it. The motor 3 is used to drive the screw 5 to rotate and move the digestion assembly 6 up and down along the setting direction of the screw 5.

[0045] In a specific implementation, the digestion component 6 is slidably matched with the first box body 1 and the second box body 2, and can only move up and down but cannot rotate. Therefore, when the motor 3 is started, the screw 5 rotates clockwise or counterclockwise, which will drive the digestion component 6 to move up or down, thereby moving the digestion component 6 into the first box body 1 or the second box body 2.

[0046] In one embodiment, the transmission assembly 8 includes a first transmission wheel group 81, a rotating shaft 82 is vertically installed in the first box body 1 and the second box body 2, the first transmission wheel group 81 includes two transmission wheels and a transmission belt arranged on the two transmission wheels, and the two transmission wheels are coaxially installed on the lead screw 5 and the rotating shaft 82, so when the lead screw 5 rotates, the rotating shaft 82 can be driven to rotate synchronously with the first transmission wheel group 81; the other end of the rotating shaft 82 away from the first transmission wheel group 81 is provided with a second transmission wheel group 83 with the same structure as the first transmission wheel group 81, and a rotating rod is rotatably installed vertically on the inner top wall of the second box body 2, and the two transmission wheels in the second transmission wheel group 83 are coaxially installed on the rotating shaft 82 and the rotating rod, respectively, and the rotating shaft 82 When rotating, it cooperates with the second transmission wheel group 83 to drive the rotating rod to rotate synchronously. An adjusting rod 84 is rotatably installed horizontally in the second box body 2, and a bevel gear group 85 is arranged at the bottom of the rotating rod, wherein the bevel gear group 85 is composed of two bevel gears meshing with each other, and the two bevel gears are coaxially installed on the rotating rod and the adjusting rod 84 respectively. An inner ratchet assembly 86 is installed at the end of the adjusting rod 84 away from the bevel gear group 85, and a reciprocating screw 87 is installed at the end of the inner ratchet assembly 86 away from the bevel gear group 85; a guide rod 10 is installed on the top of the detection component 9, and a horizontally arranged and strip-shaped guide groove is opened on the inner top wall of the second box body 2, and the top of the guide rod 10 extends into the guide groove, and the detection component 9 is threadedly matched with the reciprocating screw 87.

[0047] In a specific implementation, when the digestion component 6 moves upward and the shaft 82 rotates in one direction, the inner ratchet component 86 cooperates with the reciprocating screw 87 to rotate, and when the shaft 82 rotates in the other direction, the inner ratchet component 86 will not drive the reciprocating screw 87 to move. The setting of the inner ratchet component 86 makes the reciprocating screw 87 rotate together only when the shaft 82 rotates in the direction that drives the digestion component 6 to rise. Specifically, in the initial state, when the digestion component 6 is located in the second housing 2 and there is water in the detection chamber 62 on the left side, the detection component 9 is aligned with the detection chamber 62 on the right side. When the digestion component 6 is driven to descend to the inside of the first housing 1, the detection component 9 will not move. After cooling is completed and the reagent is injected, the digestion component 6 is driven to rise into the second box body 2. During this process, the internal ratchet component 86 will drive the reciprocating screw 87 to rotate, thereby causing the detection component 9 to move laterally to the left. When the digestion component 6 is completely raised into the second box body 2, the detection component 9 moves to align with the detection window 64 on the left side. At this time, the detection end of the detection component 9 can detect the water in the detection chamber 62 on the left side through the detection window 64. After the detection is completed, the water in the detection chamber 62 on the left side has been discharged, and there is a second water sample in the detection chamber 62 on the right side. Therefore, the water sample in the detection chamber 62 on the right side can be detected by continuing to work in the above manner. This method can be cyclically operated to repeat the detection.

[0048] In one embodiment, a water removal component 12 is disposed in the second housing 2 , and the water removal component 12 is used to remove water from the digestion component 6 that rises from the first housing 1 to the second housing 2 .

[0049] With such a design, since there is cooling water in the first box body 1, when the digestion component 6 rises from the first box body 1 to the inside of the second box body 2, if there is a lot of moisture on the surface of the digestion component 6, it will affect the detection accuracy of the detection component 9. Therefore, through the setting of the dehydration component 12, when the digestion component 6 rises to the inside of the second box body 2, the dehydration component 12 wipes its surface, thereby effectively ensuring the detection accuracy of the detection component 9.

[0050] In one embodiment, the dewatering component 12 includes a wiping brush 121. When the digestion component 6 rises and enters the interior of the second box body 2, it contacts the wiping brush 121. The wiping brush 121 is used to wipe the moisture at the corresponding detection window 64 of the digestion component 6. An opening 122 is opened on the side wall of the second box body 2. A blowing device is also provided in the second box body 2. The blowing end of the blowing device faces the digestion component 6 and is used to dry the detection window 64.

[0051] In a specific implementation, the wiping brush 121 can be provided with a horseshoe-shaped wiping brush 121, which has a missing portion, which corresponds to the sliding fit between the digestion component 6 and the first box body 1 and the second box body 2. Therefore, when the digestion component 6 rises and falls, the sliding connection between it and each box body will not be stuck by the wiping brush 121. When the digestion component 6 rises to the inside of the second box body 2, the wiping brush 121 will wipe the surface of the digestion component 6, and the blowing device will blow air to the digestion component 6, so that the surface of the digestion component 6 wiped by the wiping brush 121 will be cleaned. The moisture still existing on the surface of the detection window 64 is blown away, thereby ensuring the detection accuracy. In addition, the device also includes an air outlet (not shown in the figure), which is opened on the side wall of the first box body 1, and the setting height of the air outlet is higher than the liquid level of the cooling water inside the first box body 1. The cooling water will not flow out of the first box body 1 from the air outlet. The wind used to dry the detection window 64 will pass through the wiping brush 121 and enter the first box body 1, and it will eventually be blown out from the air outlet, thereby taking away the moisture on the wiping brush 121.
