Description

Technical Field

[0001] The utility model relates to the technical field of water quality detection, in particular to an automatic water quality detection device. Background Art

[0002] Water quality testing is a means of evaluating water quality in industrial enterprises. It is helpful to evaluate whether the water quality meets the water quality standards, provides a scientific basis for improving water quality, and plays a vital role in industrial or residential water use.

[0003] For some enterprises, according to industrial application requirements, it is often necessary to detect the pH (acidity or alkalinity of a solution or substance, hereinafter referred to as pH), conductivity, chloride ions, temperature, and ORP (oxidation-reduction potential of a solution, hereinafter referred to as ORP) of water. The existing technology is to collect sampled water at the sampling point of the production site and use the sampled water as the water to be tested for testing. The detection means used is direct detection, specifically: direct detection in the diversion trough or a filter is provided in the diversion trough, and the water to be tested is filtered before testing. However, direct detection may cause the water to be tested to contain silt, dirt, and sediment, which will be attached to the sensor probe, making it difficult to accurately detect pH, conductivity, chloride ions, temperature, and ORP, so as to affect the detection accuracy; the filter can only filter a part of the silt, and the smaller particles of silt are still not filtered, which also affects the detection accuracy. If a filter with too high fineness is selected, it will affect the water flow rate and the efficiency of the detection work. Moreover, when the attachments on the sensor probe need to be manually cleaned regularly, the filter also needs to be manually cleaned, which increases the cost and trouble of manual maintenance.

[0004] The above two types of detection have problems of affecting detection accuracy and requiring manual lifting and cleaning, which increases maintenance work and costs. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides an automatic water quality detection device, which automatically processes the water to be detected before detection through a diversion groove, and the detection groove automatically detects the water quality.

[0006] In order to achieve the above object, the utility model is implemented through the following technical solutions:

During this period, a small amount of silt and sediment contained in the water to be tested settles on the bottom wall of the diversion trough, achieving the effect of sedimentation and clarification. The sludge formed after precipitation is discharged from the diversion trough by vibration through an ultrasonic cleaner.

[0018] Further preferably, a fixing part is connected to the transmission line of the water quality sensor, and the fixing part includes:

[0049] The water inlet area 11 is arranged at one end of the guide groove 1 and is used to filter dirt in the water to be tested.

[0050] The overflow area 14 is arranged at the other end of the guide channel 1 and is connected to the water inlet area 11, and is used for settling silt and sediment through low water inlet and high overflow.

[0051] The detection tank 2 is located on one side of the guide tank 1, and is integrally connected to the overflow area 14, and a water quality sensor 4 is arranged on its inner wall. The water quality sensor 4 is detachably connected to the inner wall of the detection tank 2 and the inner wall of the guide tank 1, and the water quality sensor 4 is used to sense the water quality of the water to be tested from the overflow area 14. Specifically, the number of water quality sensors 4 is at least 3, which are used to detect the conductivity, pH, chloride ions, temperature and ORP of water respectively. Furthermore, in this embodiment, the number of water quality sensors selected is 3, which are used to detect chloride ions, ORP and pH in water respectively.

[0052] The dirt, silt and sediment in the water to be tested are removed in the diversion trough 1.

[0053] Specifically, Figure 1 and Figure 2 As shown, the overflow area 14 in this embodiment is respectively provided with:

[0054] The filter cotton 12 is located between the overflow area 14 and the water inlet area 11, and its side wall is connected to the inner wall of the guide groove 1. There is a gap between its bottom wall and the bottom wall in the guide groove 1, which is used to filter the sediment and dirt in the water to be tested. The filtered water to be tested flows into the overflow area 14 through the gap. Specifically, the filter cotton 12 can be PP (polypropylene) filter cotton 12.

[0055] The baffle 13 is arranged on the bottom wall of the guide groove 1 and is located in the overflow area 14 . Its top wall is lower than the top wall of the filter cotton 12 . The bottom wall is integrally connected to the bottom wall of the guide groove 1 to form an overflow space with the filter cotton 12 .

[0057] After most of the silt and dirt in the water to be tested are adsorbed or blocked by the filter cotton 12, the water to be tested flows from the gap into the overflow space, and gradually builds up the liquid level from bottom to top in the overflow space. During this period, a small amount of silt and sediment contained in the water to be tested settles on the bottom wall of the guide groove 1, achieving the effect of sedimentation and clarification.

[0060] There are two card blocks 82 , which are fixed on the back plate 81 and located at the inner side of the detection slot 2 . The two card blocks 82 are located opposite to each other and at a distance from each other.

[0061] The clamping groove 83 is formed on the inner wall of the clamping block 82 and contacts the transmission line 41 , so as to assist the clamping block 82 in holding the transmission line 41 .

[0062] The block 82 clamps the transmission line 41 on the back plate 81 , and the transmission line 41 is clamped on the detection tank 2 through the back plate 81 , so that the water quality sensor 4 is installed on the detection tank 2 .

[0063] Specifically, Figure 3 As shown, in this embodiment, the surface of the slot 83 is a concave curved surface, which can fit tightly with the surface of the transmission line 41. The transmission line 41 is tightened by clamping the block 82, so that the water quality sensor 4 can be hung on the back plate 81.

[0064] Specifically, Figure 3 As shown, in this embodiment, the material of the clamping block 82 is synthetic rubber. The clamping block 82 made of synthetic rubber not only has a certain hardness, but also has good toughness, and can well tighten the transmission line 41.

[0065] Specifically, Figure 5 and Figure 6 As shown, in this embodiment, the distance between the two cards 82 is 0.8 times the diameter of the transmission line 41 , so that the transmission line 41 can be firmly clamped between the cards 82 .

[0066] Specifically, Figure 1 , Figure 2 as well as Figure 4 As shown, it also includes:

[0067] The sewage pipe 10 is respectively arranged on the guide groove 1 and the detection groove 2, and is located on one side of the ultrasonic cleaner 9, and is used to discharge the sediments deposited on the inner bottom wall of the guide groove 1 and the inner bottom wall of the detection groove 2.

[0068] The solenoid valve 6 is arranged on the sewage pipe 10 and is used for automatically discharging the sediment in the guide groove 1 and the detection groove 2 .

[0069] The drain pipe 5, whose inlet portion extends into the detection tank 2, is used to discharge the detected water, and realizes automatic sewage discharge through the solenoid valve 6 and the sewage pipe 10, and then cooperates with the drain pipe 5 to realize automatic water quality detection and automatic drainage.

[0070] Specifically, Figure 5 As shown, the inlet of the drain pipe 5 in this embodiment is higher than the detection end of the water quality sensor 4, ensuring that the drain pipe 5 meets the drainage requirements.

[0071] Specifically, Figure 4 As shown, an overflow hole 20 is opened on the detection groove 2 in this embodiment, and the overflow hole 20 passes through the upper inner wall connecting the detection groove 2 and the guide groove 1, and is used to drain the water to be tested in the overflow area 14 to the detection groove 2, so that the guide groove 1 provides purified water to the detection groove 2, thereby ensuring the detection accuracy of the water quality sensor 4.

[0072] Specifically, Figure 4 As shown, in this embodiment, the solenoid valve 6 is a timer switch solenoid valve to achieve the purpose of automatic sewage discharge within a preset time period.

[0073] Please combine Figure 1-Figure 6 , the automatic cleaning process of this embodiment is described as follows.

[0074] The water to be tested enters the water inlet area 11 of the guide trough 1 from the water inlet pipe 3, and the filter cotton 12 absorbs and blocks the silt in the water to be tested and absorbs dirt, thereby purifying the water to be tested for the first time. The water to be tested enters the overflow area 14 from the gap and gradually establishes a liquid level. When the water level rises to the top surface of the baffle 13, it overflows and flows down to the space between the baffle 13 and the inner wall of the guide trough 1, and gradually forms a liquid level, and a small amount of silt and dirt in the water to be tested can also settle on the bottom wall of the guide trough 1. The ultrasonic cleaner 9 in the guide trough 1 works to vibrate the silt on the bottom wall. After the water level reaches the overflow hole 20, it enters the detection trough 2, and the water quality sensor 4 detects the water quality of the water to be tested, specifically: 3 sensors detect the chloride ions, PH and ORP of the water quality respectively. During this period, the ultrasonic cleaner 9 in the detection trough starts to vibrate the dirt attached to the working probe of the water quality sensor 4, and the ultrasonic cleaner 9 in the guide trough 1 works to vibrate the silt on the bottom wall. The electromagnetic valve 6 opens within a preset time to discharge the water, thereby achieving the purpose of automatically purifying the water to be tested and automatically detecting the water quality. This process reduces the cost and trouble of manual maintenance, and also serves to ensure that the water quality sensor 4 is free of dirt in real time, thereby improving the detection accuracy.

[0075] This specific embodiment is merely an explanation of the utility model, and it is not a limitation of the utility model. After reading this specification, those skilled in the art can make non-creative modifications to the embodiment as needed, but as long as it is within the protection scope of the utility model, it is protected by the patent law.
