Description

Technical Field

[0001] The utility model belongs to the technical field of chemical wastewater detection and relates to a device for detecting the content of heavy metal ions in chemical wastewater. Background Art

[0002] After use, purified water changes its physical or chemical properties, becoming wastewater containing various impurities. Chemical wastewater is wastewater discharged from chemical production, including process wastewater, cooling water, exhaust gas scrubbing water, and equipment and site flushing water. If discharged without treatment, these wastewaters can cause varying degrees of contamination, endangering human health and impacting industrial and agricultural production. Therefore, wastewater discharged from chemical production typically requires treatment until it meets discharge or use standards before it can be discharged or used.

[0003] Heavy metals are one of the main pollutants in chemical wastewater. During the chemical wastewater treatment process, heavy metals must be removed to reduce the heavy metal ion content within the required range. Chemical production units typically collect and store chemical wastewater in sewage treatment tanks for centralized treatment. However, the wastewater stored in these tanks can have varying levels of contamination. Therefore, during the chemical wastewater treatment process, heavy metal ion content testing is required for chemical wastewater at different depths to more accurately confirm the treatment effect, thereby reducing the probability and risks of discharging or using substandard water.

[0004] Therefore, it is necessary to provide a device for detecting the heavy metal ion content of chemical wastewater, which is convenient for detecting the heavy metal ion content of sewage at different depths in the sewage treatment pool, so as to understand the heavy metal treatment status of chemical wastewater. Utility Model Content

[0006] In order to achieve the above purpose, the present invention is implemented through the following technical solutions:

[0007] The device includes a bracket 1, an electric push rod 2, a water entry rod 3, a fixing ring 4, and a heavy metal ion detection sensor 5. The fixed section of the electric push rod 2 can be detachably installed on the bracket 1, and the bracket 1 is installed on the edge of the sewage treatment pool. The end of the telescopic section of the electric push rod 2 can be detachably connected to the water entry rod 3. The fixing ring 4 is fixed on the water entry rod 3, and the heavy metal ion detection sensor 5 can be detachably installed in the fixing ring 4.

[0008] Preferably, the device also includes a water-blocking tube 6, which is fixedly mounted on the bracket 1, and the axis of the water-blocking tube 6 coincides with the axis of the telescopic section of the electric push rod 2. The bottom of the water-blocking tube 6 is closed and the top is open. The extension direction of the telescopic section of the electric push rod 2 is toward the top opening of the water-blocking tube 6. The water entry rod 3 is a U-shaped structure and its two parallel rods are of unequal lengths, wherein the shorter one is the short rod 301 and the longer one is the long rod 302. The end of the short rod 301 is threadedly connected to the end of the telescopic section of the electric push rod 2 through a threaded sleeve 8 and the side wall of the short rod 301 is in contact with the side wall of the telescopic section of the electric push rod 2. The fixing ring 4 is fixedly set on the long rod 302, and the long rod 302 is located outside the water-blocking tube 6.

[0009] Preferably, the bracket 1 includes an L-shaped vertical frame 101 and an L-shaped side mounting plate 102. A top mounting plate 7 is fixedly arranged on the fixed section of the electric push rod 2. One end of the L-shaped vertical frame 101 is bolted to the top mounting plate 7, and the other end of the L-shaped vertical frame 101 is fixedly connected to the L-shaped side mounting plate 102. The L-shaped side mounting plate 102 is horizontally arranged and one end thereof is fixedly connected to a water-blocking tube 6. The other end of the L-shaped side mounting plate 102 is installed on the edge of the sewage treatment tank.

[0010] Preferably, a through hole is provided on the L-shaped side mounting plate 102, and the L-shaped side mounting plate 102 is installed at the edge of the sewage treatment tank by screws passing through the through hole and nailing the L-shaped side mounting plate 102 into the edge of the sewage treatment tank.

[0011] Preferably, there is at least one fixing ring 4 . When there are multiple fixing rings 4 , different fixing rings 4 are arranged at different heights, and a heavy metal ion detection sensor 5 is installed in each fixing ring 4 .

[0014] Beneficial effects of the utility model:

[0015] 1. The utility model drives the water entry rod to descend or rise by extending and retracting the telescopic section of the electric push rod, thereby driving the heavy metal ion detection sensor to descend or rise in the water. When the electric push rod stops extending and retracting, the heavy metal ion detection sensor can stay in the water at different depths to detect the heavy metal ion content, thereby facilitating the detection of heavy metal ion content in water bodies at different depths.

[0016] 2. The utility model provides a water entry rod and installs a heavy metal ion detection sensor on the water entry rod. When the liquid level in the sewage treatment pool is low, the telescopic section of the electric push rod is prevented from being immersed in sewage, which causes the sewage to corrode the telescopic section of the electric push rod, causing damage to the telescopic section of the electric push rod, thereby extending the service life of the electric push rod.

[0017] 3. The utility model sets a water-blocking cylinder. When the liquid level in the sewage treatment pool is high, the telescopic section of the electric push rod is separated from the water body by the water-blocking cylinder, so as to prevent the sewage water body from corroding the telescopic section of the electric push rod and accelerating the damage of the telescopic section of the electric push rod. At the same time, the bottom of the water-blocking cylinder is closed and the top is open. The telescopic section of the electric push rod can be telescoped inside the water-blocking cylinder. During the telescopic process, the telescopic section of the electric push rod will not come into contact with the sewage water body.

[0018] 4. The utility model sets multiple fixing rings at different heights on the water entry rod. After installing heavy metal ion detection sensors in the fixing rings, the heavy metal ion content in water bodies of different depths at the same water body position can be detected simultaneously, which is beneficial to improving detection efficiency.

[0019] 5. The utility model is provided with a wire clamping device, which can clamp the wires of the heavy metal ion detection sensor into the wire clamping device to avoid the wires from being tangled. On the one hand, it is convenient for disassembly and assembly of the heavy metal ion detection sensor. On the other hand, it can also reduce the damage of the heavy metal ion detection sensor caused by the wires being caught and pulled by other components.

[0020] 6. The utility model has a simple structure, low use cost and is suitable for industrial application. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The present invention will be described in further detail below with reference to the accompanying drawings.

[0026] like Figure 1-3As shown, the device includes a bracket 1, an electric push rod 2, a water entry rod 3, a fixing ring 4, and a heavy metal ion detection sensor 5. The fixed section of the electric push rod 2 can be detachably mounted on the bracket 1, and the bracket 1 is mounted on the edge of the sewage treatment pool. The end of the telescopic section of the electric push rod 2 can be detachably connected to the water entry rod 3. A fixing ring 4 is fixed on the water entry rod 3, and the heavy metal ion detection sensor 5 can be detachably mounted in the fixing ring 4.

[0027] When chemical wastewater detection is required, first install the electric push rod 2 on the bracket 1, then install the water entry rod 3 at the end of the telescopic section of the electric push rod 2, and then install the heavy metal ion detection sensor 5 in the fixing ring 4. The electric push rod 2 can be installed on the bracket 1 by bolts or clips, and the water entry rod 3 can be installed at the end of the telescopic section of the electric push rod 2 by bolts or clips. The heavy metal ion detection sensor 5 can be installed in the fixing ring 4 by clipping or threading with the fixing ring 4. The bracket 1 can be installed on the edge of the sewage treatment pool by nailing, screwing or using a riding card. After the device is installed, start the electric push rod 2. When the liquid level in the sewage treatment pool is low and the telescopic section of the electric push rod 2 is in the shortest state, the heavy metal ion detection sensor 5 may not be immersed in the sewage water body. At this time, first control the electric push rod 2 to extend. The extension of the electric push rod 2 drives the water entry rod 3 to descend, so that the heavy metal ion detection sensor 5 installed in the fixed ring 4 descends and is immersed in the water body. Afterwards, when the heavy metal ion detection sensor 5 is at a depth in the water body where the heavy metal ion content needs to be detected, control the electric push rod 2 to stop, and the heavy metal ion detection sensor stops moving and stays at the required depth to detect the heavy metal ion content. If the liquid level in the sewage treatment pool is high, after the device is installed, the heavy metal ion detection sensor 5 has been immersed in the sewage water body, then it is only necessary to start the electric push rod 2 to drive the heavy metal ion detection sensor 5 down to the required depth to detect the heavy metal ion content at the corresponding depth. If it is necessary to drive the heavy metal ion detection sensor 5 up, the telescopic section of the electric push rod 2 can be controlled to shorten. Since the heavy metal ion detection sensor 5 is installed on the water entry rod 3 through the fixing ring 4, if the wastewater level in the sewage treatment pool is low, the electric push rod 2 does not need to be immersed in the water body, and only the water entry rod 3 needs to be immersed in the water body. If the telescopic section of the electric push rod 2 is damaged, the electric push rod 2 needs to be replaced, which requires a higher cost. The water entry rod 3 is detachably connected to the telescopic section of the electric push rod 2. After the water entry rod 3 is damaged, it is convenient to replace. At the same time, the electric push rod 2 is detachably connected to the bracket 1, and the heavy metal ion detection sensor 5 is detachably connected to the fixing ring 4, which is convenient for replacing the electric push rod 2 and the heavy metal ion detection sensor 5.

[0028] Since the utility model has a simple structure and is easy to install and use, the utility model device can be installed at different positions on the edge of the sewage treatment pool, and then the heavy metal ion detection sensors at different positions can be adjusted to different depths in the water body for detection. The heavy metal ion content of multiple sites and multiple water depths can be detected at the same time, which helps to improve the detection efficiency.

[0029] The device also includes a water-blocking tube 6, which is fixedly mounted on the bracket 1. The axis of the water-blocking tube 6 coincides with the axis of the telescopic section of the electric push rod 2. The bottom of the water-blocking tube 6 is closed and the top is open. The telescopic section of the electric push rod 2 is extended in the direction toward the top opening of the water-blocking tube 6. The water entry rod 3 is a U-shaped structure and its two parallel rods are of unequal lengths, wherein the shorter one is the short rod 301 and the longer one is the long rod 302. The end of the short rod 301 is threadedly connected to the end of the telescopic section of the electric push rod 2 through a threaded sleeve 8 and the side wall of the short rod 301 is in contact with the side wall of the telescopic section of the electric push rod 2. The fixing ring 4 is fixedly set on the long rod 302, and the long rod 302 is located outside the water-blocking tube 6.

[0030] When the amount of wastewater in the sewage treatment pool is large and the liquid level is high, after the device is installed, the telescopic section of the electric push rod 2 may inevitably be immersed in the sewage water body. The water-blocking cylinder 6 can separate the sewage water body from the telescopic section of the electric push rod 2. The telescopic section of the electric push rod 2 is telescoped in the water-blocking cylinder 6 and does not contact the sewage water body, thereby avoiding damage to the electric push rod 2 by the sewage water body. It is only necessary to pay attention to the extension distance of the electric push rod 2 to avoid collision between the water-entry rod 3 and the water-blocking cylinder 6.

[0031] The bracket 1 includes an L-shaped vertical frame 101 and an L-shaped side mounting plate 102. A top mounting plate 7 is fixedly arranged on the fixed section of the electric push rod 2. One end of the L-shaped vertical frame 101 is bolted to the top mounting plate 7, and the other end of the L-shaped vertical frame 101 is fixedly connected to the L-shaped side mounting plate 102. The L-shaped side mounting plate 102 is horizontally arranged and one end thereof is fixedly connected to a water-blocking tube 6. The other end of the L-shaped side mounting plate 102 is installed on the edge of the sewage treatment tank.

[0032] The structure of the bracket 1 is relatively simple and easy to manufacture.

[0033] The L-shaped side mounting plate 102 is provided with a through hole, and the L-shaped side mounting plate 102 is screwed through the through hole and nailed into the edge of the sewage treatment tank to install the L-shaped side mounting plate 102 at the edge of the sewage treatment tank.

[0034] The L-shaped side mounting plate 102 is easy to install. When disassembling, the L-shaped side mounting plate 102 can be removed by simply unscrewing the screws out of the edge of the sewage treatment tank. At the same time, the entire device is also removed from the edge of the sewage treatment tank, making it easy to move the device.

[0035] There is at least one fixing ring 4 . When there are multiple fixing rings 4 , different fixing rings 4 are arranged at different heights, and a heavy metal ion detection sensor 5 is installed in each fixing ring 4 .

[0036] Heavy metal ion detection sensors 5 are installed in multiple fixed rings 4 at different height positions. When the telescopic section of the electric push rod 2 stops telescoping, the heavy metal ion detection sensors 5 at different height positions will stay at different depths in the water body, so that water bodies at different depths at the same position can be detected simultaneously, which is beneficial to improving detection efficiency.

[0037] The device further comprises a line-gripping device 9 , which is fixedly mounted on the water entry rod 3 and is located directly above the fixing ring 4 . The number of the line-gripping devices 9 is the same as the number of the fixing rings 4 .

[0038] The wire-holding device 9 includes a wire-holding tube 901 and a connecting plate 902 . The wire-holding tube 901 is fixedly mounted on the water entry rod 3 via the connecting plate 902 .

[0039] The heavy metal ion detection sensor 5 may have its own wires. When the wires of the heavy metal ion detection sensor 5 are electrically connected to the control system, the heavy metal ion detection sensor 5 transmits the detection results to the control system for storage. The staff obtains the detection results through the control system. Therefore, the wires electrically connecting the heavy metal ion detection sensor 5 and the control system can be clamped into the wire clamping tube 901 to avoid random and disorderly interweaving of the wires, entanglement or hanging with other components, etc., which affects the use and disassembly of the heavy metal ion detection sensor 5.

[0040] The working process of the utility model is as follows: the various components of the utility model are installed, and then the bracket is installed at the edge of the sewage treatment pool, the electric push rod is started, and the heavy metal ion detection sensor is driven to rise and fall. When the heavy metal ion detection sensor is located at the required depth in the water body, the electric push rod is stopped, and the heavy metal ion detection sensor detects the water body at the depth at which it stays, and transmits the detection results to the control system and other equipment, so that the staff can obtain the detection results.

[0041] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
