Description

Technical Field

[0001] The invention relates to the technical field of waste liquid detection, and more specifically to a detection and separation device for acid and alkali waste liquid after decontamination treatment of guardrail fasteners. Background Art

[0002] During the processing of guardrail fasteners such as bolts, the bolts can be pickled or alkaline washed to remove residual dirt on the surface of the guardrail fasteners. However, acid and alkaline liquids cannot be discharged at will, so the waste liquid needs to be centrally treated, and the mixture of acidic waste liquid and alkaline waste liquid will react violently. If toxic gases are generated, it will also endanger the workers, so acid and alkaline waste liquids need to be stored separately. At present, the detection and separation of acid and alkaline waste liquids are all done manually; when manually detecting and separating acid and alkaline waste liquids, acid and alkaline measuring devices and acid and alkaline waste liquid storage boxes are required. After the acid and alkalinity of the waste liquid are detected by the acid and alkaline measuring device, the acid and alkaline waste liquids are separated and poured into the acid waste liquid storage box and the alkaline waste liquid storage box according to the activity of hydrogen ions in the waste liquid, so that the acid waste liquid and the alkaline waste liquid are stored separately.

[0003] However, manual detection of acid and alkali waste liquid has the following shortcomings:

[0004] First, after each detection of the acidity and alkalinity of the waste liquid, waste liquid will remain inside the acid-base measuring device. When acidic waste liquid remains inside the measuring device, the acid-base waste liquid will react unpredictably during the subsequent alkaline waste liquid detection, causing adverse effects. Therefore, at present, after the acidity and alkalinity of the waste liquid are measured, the staff will use clean water to rinse the detection device to prevent the residual waste liquid in the detection device from reacting with the waste liquid measured later, resulting in low efficiency of manual measurement of acid-base waste liquid and delaying work time;

[0005] Secondly, manual testing of acid and alkali waste liquid needs to be carried out strictly according to the steps. After the waste liquid after the reaction is collected, the acid-base measuring device is inserted into the waste liquid. After the result is obtained, the liquid is poured into the corresponding storage box, and then the container for collecting the waste liquid and the measuring device are cleaned. The steps are relatively cumbersome, which makes it easy for the staff to make mistakes when separating the acid and alkali waste liquid.

[0006] Therefore, there is an urgent need for a detection and separation device for acid and alkali waste liquid after decontamination treatment of guardrail fasteners, which can automatically separate and collect the poured waste liquid. Summary of the invention

All other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0033] Reference Figure 1 and Figure 2 The present invention provides a detection and separation device for acid and alkaline waste liquid after decontamination treatment of guardrail fasteners, comprising a waste liquid collecting device 1, a waste liquid detecting device 3 for detecting the acidity and alkalinity of the waste liquid is fixedly connected to the bottom of the waste liquid collecting device 1, a waste liquid storing device 4 for storing acidic and alkaline waste liquids separately is movably connected to the bottom of the waste liquid detecting device 3, a separation device 6 located at the top of the waste liquid storing device 4 is movably connected to the bottom of the waste liquid detecting device 3, injection devices 2 for adding acidic and alkaline solutions are fixedly connected to both sides of the waste liquid collecting device 1, a cleaning device 7 is fixedly connected to the back of the waste liquid storing device 4, a spraying device 5 is fixedly connected to the top of the cleaning device 7, and an injection device 2 located at the bottom of the spraying device 5 is fixedly connected to the side of the waste liquid collecting device 1.

[0034] In this embodiment, it needs to be specifically explained that the cleaning device 7 transmits water to the spraying device 5, and the spraying device 5 cleans the inner wall of the injection device 2 by spraying water to remove the residual waste liquid, and the water flow flushes the internal waste liquid of the entire device from top to bottom. The waste liquid detection device 3 measures the acidity and alkalinity of the waste liquid flowing out of the waste liquid collection device 1 by detecting the hydrogen ion activity, and the pouring device 6 pours the acid and alkaline waste liquids into different containers in the waste liquid storage device 4 respectively to avoid the acid and alkaline waste liquids from mixing and reacting.

[0035] Reference Figure 3 and Figure 4The waste liquid collecting device 1 comprises a waste liquid cup 101, a fixing ring 102 is fixedly connected to the middle of the outer surface of the waste liquid cup 101, arc-shaped conduits 206 for transmitting acid and alkali solutions located above the fixing ring 102 are fixedly connected to both sides of the waste liquid cup 101, and a hand wheel 208 is movably connected to one side of the two arc-shaped conduits 206, a protrusion 106 for improving sealing is movably connected to the top of the waste liquid cup 101, a cup cover 104 is fixedly connected to the top of the protrusion 106, and a limiting ring 105 located on the outside of the protrusion 106 but not in contact with the protrusion 106 is fixedly connected to the outer side of the bottom of the cup cover 104, and the waste liquid A straight conduit 103 is fixedly connected in the middle of the bottom of the cup 101, a collecting cup 201 for adding acid and alkali solutions is fixedly connected to the top of the arc conduit 206, a fixing ring 202 is fixedly connected to the outer surface of the collecting cup 201, a sealing ring 203 located outside the arc conduit 206 is fixedly connected to the bottom of the collecting cup 201, a support rod 204 is fixedly connected to one side of the fixing ring 202, a connecting rod 205 is fixedly connected to one side of the bottom of the support rod 204, a valve 207 is fixedly connected to one side of the handwheel 208, and the fixing ring 202 and the connecting rod 205 are fixedly connected via the support rod 204.

[0036] In this embodiment, it needs to be specifically explained that the acid and alkali solutions enter the waste liquid cup 101 respectively through two arc-shaped conduits 206, react fully in the waste liquid cup 101, and then the remaining waste liquid flows out through the straight conduit 103 after being processed by the staff. The gap distance between the protrusion 106 and the limiting ring 105 is the same as the thickness of the side wall of the waste liquid cup 101. The waste liquid cup 101 is movably connected in the gap between the protrusion 106 and the limiting ring 105. The protrusion 106 prevents the solution inside the waste liquid cup 101 from leaking out. The hand wheel 208 is turned to control the on and off of the arc-shaped conduit 206, thereby controlling the time for the solution in the collection cup 201 to flow into the waste liquid collection device 1.

[0037] Reference Figure 5 and Figure 6The waste liquid detection device 3 includes a support 301, a detection device 303 is fixedly connected to the middle part of the support 301, a display panel 305 for displaying the pH value of the waste liquid is fixedly connected to one side of the detection device 303, a data line 608 is fixedly connected to the other side of the detection device 303, a detection tube 304 is fixedly connected to the inside of the detection device 303, both sides of the detection device 303 are fixedly connected to the connecting tube 302, one end of the data line 608 is fixedly connected to the controller 607, one side of the controller 607 is fixedly connected to the external movable rod 606, and the external movable rod 606 is fixedly connected to the external movable rod 606. An inner movable rod 605 is internally movably connected, one end of the inner movable rod 605 is fixedly connected to a connecting block 604, one side of the connecting block 604 is fixedly connected to a second liquid baffle plate 603 for preventing waste liquid from leaking out from the side of the triangular block 601, one side of the second liquid baffle plate 603 is fixedly connected to a triangular block 601 for diverting waste liquid, the two inclined surfaces of the triangular block 601 are respectively used for diverting acid and alkali waste liquids, which is convenient for separation, one side of the triangular block 601 is fixedly connected to a first liquid baffle plate 602, and both sides of the triangular block 601 are respectively fixedly connected to the first liquid baffle plate 602 and the second liquid baffle plate 603.

[0038] In this embodiment, it is necessary to explain in detail that the bottoms of the two inclined surfaces of the triangular block 601 are both provided with notches, and guide strips are installed on both sides of the triangular block 601, the purpose of which is to reduce the amount of waste liquid remaining on the triangular block 601. When the waste liquid flows to the surface of the triangular block 601, the first liquid baffle plate 602 and the second liquid baffle plate 603 limit the waste liquid to the top of the triangular block 601 to prevent the waste liquid from leaking from the side of the triangular block 601. The inner movable rod 605 pushes and pulls the connecting block 604 to drive the triangular block 601 to move, and the detection device 303 changes the triangular block 601 by detecting the acidity and alkalinity of the waste liquid. The waste liquid flows down through different slopes on the top of the triangular block 601, so that the acid and alkaline waste liquids are stored separately. The solution injected into the collection cup 201 is directly allowed to enter the detection device 303 through the connecting pipe 302 by controlling the valve 207, or the solution is allowed to react in the waste liquid collection device 1 before entering the detection device 303. The acid and alkaline solutions are directly processed and enter the inner storage box 401 when not needed. The connecting pipe 302 is connected to the detection tube 304. The detection device 303 is used to detect the acidity and alkalinity of the waste liquid passing through the detection tube 304 and control the on-off of the detection tube 304.

[0039] Reference Figure 7 and Figure 8The waste liquid storage device 4 includes an inner storage box 401, a top of the inner storage box 401 is fixedly connected with an opening and closing plate 406 for preventing waste liquid from spilling, one side of the inner storage box 401 is fixedly connected with two drag handles 402, the outer side of the inner storage box 401 is movably connected with an outer storage box 408, a partition plate 407 is fixedly connected to the middle of the inner part of the outer storage box 408, the top of the partition plate 407 is fixedly connected with a support plate 410, the top of the support plate 410 is fixedly connected with a cover plate 409, one side of the outer storage box 408 is movably connected with a box door 404, and one side of the inner storage box 401 is fixedly connected with a nameplate 403, a handle 405 is fixedly connected to one side of the box door 404, the opening and closing plate 406 is movably connected to two movable plates 4061 inside, one end of the movable plate 4061 is fixedly connected to a long rod 4062, the nameplate 403 and the drag handle 402 are located on the same side of the inner storage box 401, and the nameplate 403 is located above the drag handle 402, the two movable plates 4061 are respectively located on both sides of the inside of the opening and closing plate 406, the partition 407 divides the inside of the outer storage box 408 into two cavities of the same size, and the two inner storage boxes 401 are respectively located in the two cavities inside the outer storage box 408.

[0040] In this embodiment, it needs to be specifically explained that the two inner storage boxes 401 are respectively used to store acidic waste liquid and alkaline waste liquid, and a square hole is opened on the top of the cover plate 409. The width of the square hole on the top of the cover plate 409 is four centimeters larger than the width of the triangular block 601. The waste liquid flows down the inclined surface of the triangular block 601, passes through the square hole on the top of the cover plate 409 and falls into the inner storage box 401. The two nameplates 403 respectively display the type of waste liquid in the inner storage box 401 connected thereto to avoid confusion between acidic waste liquid and alkaline waste liquid. The dragging handle 402 facilitates the removal of the inner storage box 401 when dumping the waste liquid. The movable plate 4061 moves horizontally inside the opening and closing plate 406. The purpose is to close the hole of the opening and closing plate 406 when dumping the waste liquid to prevent the internal waste liquid from spilling out. The support plate 410 supports the triangular block 601.

[0041] Reference Fig. 9 and Fig.10 The spraying device 5 includes a top plate 501, two sprinklers 502 are fixedly connected to the bottom of the top plate 501, a nozzle 503 for spraying residual waste liquid in the clean water cleaning device is fixedly connected to the bottom of the sprinkler 502, a rotating rod 505 is fixedly connected to one side of the top plate 501, and a water pipe 504 for transmitting water is fixedly connected to the bottom of the top plate 501. The cleaning device 7 includes a water tank 701, a pump 702 for making water flow in the water pipe 504 is fixedly connected to the inside of the water tank 701, a fixing plate 703 is fixedly connected to one side of the water tank 701, and a fastening bolt 704 is fixedly connected to the top of the fixing plate 703.

[0042] In this embodiment, it needs to be specifically explained that the fixed plate 703 transmits water to the sprinkler 502 through the water pipe 504, so that the water is sprayed out from the bottom of the nozzle 503 to clean the residual waste liquid inside the equipment, prevent the service life of the equipment from being affected, and prevent the residual waste liquid from reacting with the waste liquid detected later. The top plate 501 adjusts the angle through the rotating rod 505, and will not block the collection cup 201 and make it difficult to inject the solution. The water tank 701 stores clean water inside for clearing the residual waste liquid inside the device, and the fastening bolt 704 over-tightens the fixed plate 703 and the rotating rod 505.

[0043] The specific problem to be solved in this embodiment is to increase the efficiency of acid and alkali waste liquid detection and separation and avoid the danger caused by mistakes in manual waste liquid treatment. Therefore, the principles of each part of the device are as follows:

[0044] The working principle of each part of the present invention is as follows: the acid and alkali solutions are respectively injected into the two collection cups 201, and the solutions flow into the waste liquid collection device 1 from the arc-shaped conduit 206. The sealing ring 203 prevents the solution from leaking from the interface between the collection cup 201 and the arc-shaped conduit 206. The valve 207 is a three-way valve. By turning the hand wheel 208 to control the valve 207, the solution in the collection cup 201 enters the waste liquid collection device 1 or directly enters the waste liquid detection device 3.

[0045] The acid and alkali waste liquids enter the waste liquid cup 101 from the two arc-shaped conduits 206 respectively. After sufficient reaction and treatment, the waste liquid cup 101 collects the waste liquid inside. The cup cover 104, the limiting ring 105 and the protrusion 106 are used to seal the waste liquid cup 101 so that the liquid in the waste liquid cup 101 will not overflow. The waste liquid flows into the waste liquid detection device 3 through the straight conduit 103;

[0046] It plays the role of supporting the waste liquid cup 101 and protecting the detection device 303. When the waste liquid flows into the detection tube 304 from the straight conduit 103 or the connecting tube 302, the detection tube 304 is not opened. After the detection device 303 detects the acidity and alkalinity of the waste liquid, the detection tube 304 is opened, and the detection device 303 controls the controller 607 through the data line 608 to make the inner movable rod 605 push and pull the connecting block 604, driving the triangular block 601 to move in translation. The acidity and alkalinity of the waste liquid determine the moving direction of the triangular block 601. When the acidic waste liquid falls from the detection tube 304, the first liquid baffle plate 602 aligns one side of the inclined surface with the outlet of the detection tube 304, and the waste liquid slides from the inclined surface to an inner storage box 401; when the alkaline waste liquid falls from the detection tube 304, the first liquid baffle plate 602 aligns the other side of the inclined surface with the outlet of the detection tube 304, and the waste liquid slides from the inclined surface to another inner storage box 401, so as to realize the separate storage of acidic and alkaline waste liquids;

[0047] After storing enough waste liquid, the box door 404 is opened by the handle 405, and the two long rods 4062 are closed to close the opening and closing plate 406 to prevent the waste liquid from leaking out during transportation. Then, the inner storage box 401 is pulled out by dragging the handle 402 for subsequent waste liquid treatment. The support plate 410 drags the triangular block 601 to keep the triangular block 601 moving horizontally at all times.

[0048] After the acid and alkali waste liquids are tested and separated, the pump 702 transfers the water in the water tank 701 to the top plate 501 through the water pipe 504, and finally sprays the water into the collection cup 201 through the nozzle 503 to clean up the residual waste liquid to avoid affecting the next test. The fastening bolt 704 over-tightens the rotating rod 505 and the fixed plate 703, so that the friction between the rotating rod 505 and the fixed plate 703 is much greater than the gravity of the top plate 501. After adjusting the angle of the top plate 501, the top plate 501 is still relatively still with the fixed plate 703, which is convenient for adjusting the angle of the top plate 501 and injecting the solution into the collection cup 201.
