Description

Technical Field

[0001] This invention belongs to the field of wastewater detection technology, and in particular relates to an industrial wastewater detection device. Background Technology

[0002] With the development of industrialization and urbanization, wastewater discharge is increasing. In order to avoid wastewater from affecting the environment, it is necessary to treat the wastewater. The treated wastewater can only be discharged after it has been tested and meets the standards, so as to avoid the discharge of substandard wastewater that will affect the environment.

[0003] Currently, when treating wastewater in wastewater treatment plants, it is necessary to use sensors and other detection instruments to detect the wastewater at various stages in order to adjust the wastewater treatment measures based on the detection results. For example, an industrial wastewater detection device disclosed in patent publication number CN116559402B can sample and detect wastewater at different locations, increasing the representativeness of the wastewater detection results. However, this detection device is mainly suitable for detection during the wastewater treatment process. After the wastewater is treated, the purified water also needs to be strictly tested before discharge (to determine whether the purified wastewater meets the discharge requirements). Because the purified water is continuously discharged and the contact time with the water quality detection probe on the pipeline is short, some trace pollutants, such as heavy metal ions such as mercury and chromium, are difficult to detect. If these water bodies containing trace pollutants are directly discharged, they will still cause serious pollution to the environment. In addition, the complex flow state of the water body during discharge will make the pollutants not concentrated enough, affecting the accuracy of the detection results. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned problems by providing an industrial wastewater detection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an industrial wastewater detection device, comprising a base and a housing disposed above the base, wherein a gantry frame is installed on the top of the housing, and an electrical control unit is installed on the side wall of the gantry frame, and further comprising: An annular groove is formed on the top of the box body.

[0008] Preferably, the water detection mechanism includes an electric push rod fixedly inserted into the end face of the turntable, and a mounting plate is installed on the telescopic end of the electric push rod. A water quality detector is inserted into the end face of the mounting plate, and the water quality detector has at least one water quality detection probe. The water quality detection probe can detect pollutants in the water and feed the detection results back to the electrical control unit via the water quality detector. The electric push rod is electrically connected to the electrical control unit, and the water quality detector is set inside the annular groove.

[0009] Preferably, each of the heat convection units includes a sealing cover fixedly installed at the bottom of the housing, and the sealing cover can seal the water storage hole. A heating rod is fixedly installed on the top of the sealing cover, and an insulating heat-conducting cover is fitted on the outside of the heating rod. The insulating heat-conducting cover is fixedly installed on the top of the sealing cover, and the interior of the insulating heat-conducting cover is filled with a heat-conducting medium. The heating rod is electrically connected to the electrical control unit. A flow guide sleeve is fitted on the outer wall of the insulating heat-conducting cover, and the flow guide sleeve is fixedly installed on the top of the sealing cover. Multiple liquid passage holes are opened at the lower end of the side wall of the flow guide sleeve. A conical mounting sleeve is fixedly installed between the top of the flow guide sleeve and the hole wall of the water storage hole, and a detachable conical sleeve filter membrane assembly is inserted into the side wall of the conical mounting sleeve.

[0010] Preferably, the air flotation unit includes an annular cover fitted onto the upper end of the outer wall of the tank. An annular partition is fixedly installed between the inside of the annular cover and the side wall of the tank. An air pump is fixedly installed on one side of the top of the annular partition, and the air outlet of the air pump extends to the bottom of the annular partition. Multiple air injection pipes are fixedly inserted into the groove wall of the annular groove at the position below the annular partition.

Both the normally open and normally closed solenoid valves are electrically connected to the electronic control unit.

[0013] Compared with existing technologies, the advantages of an industrial wastewater detection device are: 1. Through the coordinated operation of the base, housing, gantry, electrical control unit, annular groove, water storage hole, drain pipe, electrical control valve, turntable, rotary drive mechanism, water injection mechanism, and water detection mechanism, water is stored in multiple storage zones and detected step by step. This eliminates the need to detect flowing water, ensuring sufficient contact between the water detection mechanism and the water body, as well as ensuring sufficient contact time. This reduces the possibility of pollutants not being detected and also avoids continuous impact of flowing water on the detection probe, reducing the possibility of probe damage.

[0014] 2. By setting up multiple thermal convection units, the water can be appropriately heated after it is injected. The heat convection generated by the heating drives the pollutants in the water to move upward, thereby increasing the concentration of pollutants near the water testing agency to a certain extent. Secondly, heating can increase the thermal movement of pollutants, which is conducive to the rapid and thorough detection of pollutants by the water testing agency.

[0015] 3. The air flotation unit, in conjunction with the thermal convection unit, helps suspended solids in the water to move upward. Secondly, heating accelerates the volatilization of organic pollutants in the water, and the gas detection mechanism detects the waste gas generated by the volatilization of pollutants, thus determining the pollutants in the water. This allows for a more comprehensive assessment of whether the water is polluted. Attached Figure Description

[0021] The water quality testing mechanism 12 is installed on the turntable 9. The water quality testing mechanism 12 is used to test the water quality in the water storage hole 6.

[0022] Each heat convection unit 13 includes a sealing cover 131 fixedly installed at the bottom of the housing 2, and the sealing cover 131 can seal the water storage hole 6. An electric heating rod 132 is fixedly installed on the top of the sealing cover 131, and an insulating heat-conducting cover 133 is sleeved on the outside of the electric heating rod 132.

A conical mounting sleeve 136 is fixedly installed between the top of the flow guide sleeve 134 and the hole wall of the water storage hole 6. A detachable conical sleeve filter membrane assembly 137 is inserted into the side wall of the conical mounting sleeve 136. The heat generated by the electric heating rod 132 is conducted to the water body through the heat conduction medium and the insulating heat conduction cover 133. The sealing cover 131 is used to fix the box 2 and the base 1.

[0023] The air flotation unit 14 includes an annular cover 141 sleeved on the upper end of the outer side wall of the housing 2. An annular partition 142 is fixedly installed between the inside of the annular cover 141 and the side wall of the housing 2. An air pump 143 is fixedly installed on the top side of the annular partition 142, and the air outlet of the air pump 143 extends to the bottom of the annular partition 142. Multiple air injection pipes 144 are fixedly inserted into the groove wall of the annular groove 5 at the position below the annular partition 142. A hollow ring 145 is fixedly provided between the hole wall of each water storage hole 6 and the outer side wall of the guide sleeve 134. Each air injection pipe 144 is connected to the corresponding hollow ring 145. Multiple vent holes connected to the guide sleeve 134 are opened on the inner ring wall of the hollow ring 145. The air pump 143 is electrically connected to the electrical control unit 4.

[0024] A gas detection mechanism 15 is installed at the air intake end of the air flotation unit 14. The gas detection mechanism 15 is used to detect gases volatilized from the water. The gas detection mechanism 15 includes a retaining ring 151 fixedly installed at the bottom of the turntable 9, and the retaining ring 151 is located inside the annular groove 5. A return hole 152 is opened on the side of the annular groove 5 away from the air pump 143, and the return hole 152 is connected to the inside of the annular cover 141. The return hole 152 is located on the upper side of the annular partition 142. A hollow plate is provided inside the annular cover 141 above the annular partition 142. 153. At least one gas detection probe 154 is installed on the end face of the hollow plate 153. An air inlet 155 is opened at one end of the hollow plate 153. An air suction pipe 156 is fixedly connected to the side wall of the hollow plate 153 away from the air inlet 155. The air suction pipe 156 is connected to the air suction end of the air pump 143. The gas detection probe 154 is electrically connected to the electrical control unit 4. The gas detection probe 154 can be selected according to the volatile pollutants that may exist in the wastewater. Multiple mounting holes are left on the surface of the hollow plate 153 for installing the gas detection probe 154.

[0025] Each air injection pipe 144 has a shunt pipe 16 fixedly inserted into its wall. The shunt pipe 16 is located on one side of the water quality detection probe 124. A normally closed solenoid valve 17 is installed inside the shunt pipe 16. A normally open solenoid valve 18 is installed inside the air injection pipe 144 below the shunt pipe 16. Both the normally open solenoid valve 18 and the normally closed solenoid valve 17 are electrically connected to the electronic control unit 4. After the electric push rod 121 drives the water quality detector 123 to move back to its original position, the electronic control unit 4 controls the normally closed solenoid valve 17 and the normally open solenoid valve 18 on that side to be energized. At this time, some airflow will be discharged through the shunt pipe 16, which can dry the water on the surface of the water quality detection probe 124, which is beneficial to improving the accuracy of subsequent detection by the water quality detection probe 124. When the drive motor 103 works again, the electronic control unit 4 controls the normally closed solenoid valve 17 and the normally open solenoid valve 18 to be de-energized.

[0026] The operating principle of the present invention is explained as follows: Connecting pipe 112 to an external water pump, when treating wastewater, the electronic control unit 4 is activated. After activation, the electronic control unit 4 controls the external water pump to operate. The external water pump can extract the water discharged after treatment by the wastewater treatment system and transport it into the connecting pipe 112. Subsequently, the water passes through the water cover 111 and the water injection pipe 113 into the water storage hole 6 on that side, thereby allowing water to be injected into the water storage hole 6. After activation, the electronic control unit 4 controls the drive motor 103 every 30 seconds. When the drive motor 103 works once, it can drive the rotating shaft 101 to rotate a certain angle through the gear transmission assembly 104, thereby driving the turntable 9 to rotate a certain angle (this angle is determined based on the number of water storage holes 6 set. Taking 6 water storage holes 6 as an example, the rotation angle of the turntable 9 is 60°). After the drive motor 103 finishes working once, the turntable 9 drives the water injection pipe 113 to move above the next water storage hole 6. At this time, the water discharged from the water injection pipe 113 will enter the next water storage hole 6. In the initial stage of the start-up of the electronic control unit 4, since there is no water in the water storage hole 6 below the water quality detector 123, the electronic control unit 4 will not start the water detection work at this stage. After the turntable 9 rotates 180°, the electronic control unit 4 will control the electric push rod 121 to extend for 3 seconds. The electric push rod 121 will push the mounting plate 122 to move the water quality detector 123 down. After the electric push rod 121 finishes working, the water quality detection probe 124 at the bottom of the water quality detector 123 will be inserted into the water. Then the electronic control unit 4 will control the water quality detector 123 to work. The water quality detector 123 will detect pollutants in the water through the water quality detection probe 124 and send an electrical signal back to the electronic control unit 4 when the pollutants exceed the standard. The detection time range of the water quality detection probe 124 is 20 seconds. That is, after the electric push rod 121 extends, the water quality detection probe 124 will complete the detection work within 20 seconds. Then the electronic control unit 4 will control the electric push rod 121 to move back to its original position. When water is injected into the water storage hole 6 through the water injection pipe 113, the electrical control unit 4 controls the electric heating rod 132 in the corresponding water storage hole 6 to operate. The electric heating rod 132 can generate heat when energized, with a heating temperature of 55°C. The heat is conducted to the water body through the heat transfer medium and the insulating heat transfer cover 133. As the lower side of the water body is heated, the temperature of the lower side water body rises, and the lower side water body begins to flow upward along the guide sleeve 134 (the water body at the upper temperature flows downward along the outside of the guide sleeve 134 through the conical sleeve filter membrane assembly 137, and finally replenishes the guide sleeve 134 through the liquid passage hole 135). This drives the pollutants that may be deposited on the lower side of the water body to move upward, causing them to move to the upper side of the water body, and the pollutants are filtered by the conical sleeve filter membrane assembly 137. 37 is trapped on the upper side of the water body (the conical filter membrane assembly 137 includes a conical ultrafiltration membrane, an annular pressing structure and other components), thereby increasing the pollutant concentration at the water quality detection probe 124, so as to facilitate the detection of trace heavy metal ions and other pollutants by the water quality detection probe 124 and improve the accuracy of the detection results. After the water quality detector 123 finishes detecting the water in the water storage hole 6 on this side, the electrical control unit 4 controls the electric heating rod 132 in the water storage hole 6 to stop working until the water injection pipe 113 injects water into the water storage hole 6 again. At the same time, the electrical control unit 4 will control the electric control valve 8 in the drain pipe 7 on this side to be energized and opened until the water injection pipe 113 injects water into the water storage hole 6 again, and the electric control valve 8 will be de-energized and closed. Simultaneously, after startup, the electrical control unit 4 controls the air pump 143 to operate. The air pump 143 delivers air below the annular baffle 142. The air is injected into the hollow ring 145 inside each water storage hole 6 through the air injection pipe 144, and finally discharged into the guide sleeve 134 through each vent hole. Subsequently, the airflow escapes upward through the water body. Under the action of the airflow, suspended solids and other pollutants will also accumulate on the upper side of the water body. This, combined with the heating effect, further increases the concentration of pollutants on the upper side of the water body, further reducing the possibility of pollutants being missed. Secondly, since heating can accelerate the volatilization of volatile pollutants in the water body (for example, chloroform, a common volatile organic pollutant, volatilizes faster when heated, thus escaping from the water body), the volatile gases escaping from the water body will enter the annular tank 5. Since the air pump 143's suction end passes through the inner ring of the return hole 152, A negative pressure suction is generated inside the groove 5, so the discharged volatile gas will enter the annular cover 141 through the return hole 152 (the gap between the groove wall of the annular groove 5 and the outer wall of the baffle ring 151 is within 0.1 mm, thus ensuring that the return gas flows back through the return hole 152), and enters the air inlet 155 through the air inlet 155 at the end of the hollow plate 153, and is finally drawn back by the air pump 143 through the suction pipe 156. When the gas passes through the inside of the hollow plate 153, the gas detection probe 154 at the hollow plate 153 will detect the harmful gas in the return gas, and when harmful gas is detected, it will send an electrical signal back to the electronic control unit 4, thus indicating that there are volatile organic pollutants in the water (the gas detection probe 154 can be selected according to the volatile pollutants that may be present in the sewage, and the surface of the hollow plate 153 has multiple mounting holes for installing multiple different gas detection probes 154). After the water quality analyzer 123 or the gas detection probe 154 sends an electrical signal to the electrical control unit 4, the electrical control unit 4 will send an alarm message to the personnel (e.g., via wireless communication, audible alarm, etc.). At the same time, the electrical control unit 4 will control the external water pump to stop working and control the electrical control valves 8 in each drain pipe 7 to keep them de-energized, so that the water storage hole 6 stores the water sample. After receiving the alarm message, the personnel should promptly take a sample through the water storage hole 6, inspect the water body, and promptly find the cause of water pollution. After the water pump stops working, the water body will not continue to enter the water storage hole 6, ensuring that the water sample will not be diluted. Secondly, injecting water into the water storage hole 6 through the external water pump can ensure a fixed amount of water injected at one time. In order to ensure that there is enough storage space for the purified water discharged from the sewage treatment system, a water storage tank or the like can be set at the suction end of the external water pump for temporary storage of the purified water discharged from the sewage treatment system.
