Description
Technical Field
[0001] This utility model relates to the technical field of electroplating wastewater recycling and treatment, and in particular to a fastener electroplating wastewater recycling tank. Background Technology
[0002] Fasteners are a wide range of mechanical parts used for fastening connections. They can be found in various types of machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, chemicals, meters, and supplies. They are the most widely used basic mechanical components.
[0003] With the continuous development of the national economy, advanced manufacturing, represented by large aircraft, large power generation equipment, automobiles, high-speed trains, large ships, and large complete sets of equipment, will also enter an important development direction. As a result, the use of high-strength fasteners will increase rapidly. In order to improve the wear resistance and corrosion resistance of fasteners, electroplating is required. During the electroplating process, a large amount of wastewater is generally generated, which requires the use of wastewater recycling tanks for treatment.
[0004] When existing equipment recycles and treats wastewater, staff usually need to add specific flocculants to the sedimentation tank according to the type of wastewater. However, when pouring the flocculant into the sedimentation tank, some sedimentation tanks are quite large, making it difficult for staff to pour the flocculant evenly. This results in the flocculant not reacting fully with the wastewater, which in turn directly affects the purification of the wastewater to some extent. Utility Model Content
[0005] To address the problem mentioned above where existing devices require workers to pour flocculants into sedimentation tanks during wastewater recycling, and because some sedimentation tanks are quite large, it is difficult for workers to pour the flocculants evenly into the tanks, resulting in the flocculants not reacting fully with the wastewater, this invention provides a fastener electroplating wastewater recycling tank.
[0006] This utility model provides a fastener electroplating wastewater recovery tank, which adopts the following technical solution:
[0007] A fastener electroplating wastewater recycling tank includes a recycling tank body. A vertical plate is installed inside the recycling tank body. A transition hole is opened at the upper end of the vertical plate. A filter screen plate is connected to the left side of the transition hole. A sedimentation chamber is provided at the left end of the vertical plate. A slag discharge port is opened at the bottom left side of the sedimentation chamber. A processing chamber is provided at the right end of the vertical plate. A liquid outlet pipe is connected to the bottom right side of the processing chamber. A stirring mechanism is provided inside the processing chamber. A transmission mechanism is provided on the right side of the processing chamber, and the left end of the transmission mechanism is connected to the right end of the stirring mechanism. A transverse reciprocating mechanism is provided at the top of the processing chamber. A chemical storage tank is installed between the transverse reciprocating mechanisms. An inlet is opened at the top of the chemical storage tank. A spraying mechanism is provided at the bottom of the chemical storage tank.
[0008] By adopting the above technical solution, electroplating wastewater is added into the interior of the recycling tank through the opening at the top of the tank body for sedimentation. After a period of time, large particles of impurities settle inside the recycling tank. As the water level rises, the wastewater, after initial sedimentation, enters the treatment chamber through the transition hole. When the wastewater passes through the filter screen, small particles of impurities in the water are intercepted. The liquid spraying mechanism sprays the liquid from the liquid storage tank into the treatment chamber, and the transmission mechanism drives the stirring mechanism to stir and mix the liquid and wastewater. During the mixing process, the transverse reciprocating mechanism drives the liquid storage tank to move back and forth from side to side, thereby evenly spraying the liquid into the treatment chamber and improving the wastewater treatment efficiency.
[0009] Optionally, a positioning mechanism is provided between the filter screen and the vertical plate. The positioning mechanism includes four sets of positioning posts, which are respectively installed at the four corners on the right side of the filter screen. The left side of the vertical plate has positioning holes that are inserted and matched with the positioning posts.
[0010] By adopting the above technical solution, the filter screen can be positioned by the insertion and cooperation of the positioning column and the positioning hole, so that the filter screen and the vertical plate fit together better.
[0011] Optionally, the top of the filter plate is provided with a locking mechanism, which includes a protective shell. The protective shell is installed on the upper left side of the vertical plate. A sliding plate is installed on the inner bottom wall of the protective shell. A movable rod is connected to the top of the sliding plate. The top of the movable rod extends out of the protective shell and is equipped with a rubber ball. A positioning spring is sleeved on the outer side of the movable rod. The positioning spring is located between the sliding plate and the inner top wall of the protective shell. An insertion rod is connected to the bottom of the sliding plate. The top of the filter plate has an insertion hole for insertion and engagement with the insertion rod.
[0012] By adopting the above technical solution, when it is necessary to release the fixing effect of the insertion rod on the filter screen, pull the rubber ball upward. The rubber ball drives the sliding plate to move upward through the movable rod and compresses the positioning spring. The upward movement of the sliding plate drives the insertion rod to move upward until the insertion rod separates from the insertion hole.
[0013] Optionally, the transverse reciprocating mechanism includes two sets of support plates, which are respectively installed on the top of the vertical plate and the recovery tank body. A one-way threaded column is rotatably connected between the front ends of the two sets of support plates. A servo motor for driving the one-way threaded column to rotate is installed on the outer side of the right support plate. A threaded sleeve is screwed onto the outer wall of the one-way threaded column. A smooth rod is connected between the rear ends of the two sets of support plates. A movable sleeve is slidably sleeved on the outer side of the smooth rod. The threaded sleeve and the movable sleeve are fixedly connected to the front and rear ends of the medicine storage tank on their respective sides.
[0014] By adopting the above technical solution, when the servo motor is working, it drives the one-way threaded column to rotate. Under the sliding cooperation of the guide rod and the movable sleeve, the rotation of the one-way threaded column drives the threaded sleeve to move left and right. The movement of the threaded sleeve drives the liquid storage tank to move back and forth left and right, thereby enabling the liquid to be evenly sprayed inside the treatment chamber, which improves the wastewater treatment efficiency.
[0015] Optionally, the spraying mechanism includes a liquid guide tube connected to the bottom of the liquid storage tank, a spray holder installed at the bottom of the liquid guide tube, and a plurality of spray nozzles connected to the bottom of the spray holder.
[0016] By adopting the above technical solution, the liquid medicine enters the interior of the spray holder through the liquid guide pipe, and the spray holder sprays the liquid medicine into the interior of the treatment chamber through the nozzle, so that the liquid medicine mixes with the wastewater and reacts.
[0017] Optionally, a solenoid valve is installed inside the liquid guide pipe, a control valve is installed on the liquid outlet pipe, a pH detector is installed on the inner bottom wall of the processing chamber, a controller is installed on the right side of the recovery tank body, the output end of the pH detector is electrically connected to the input end of the controller, and the output end of the controller is electrically connected to the input ends of the solenoid valve and the control valve respectively.
[0018] By adopting the above technical solution, when the pH detector detects that the pH value of the electroplating wastewater in the treatment chamber has reached the set pH value, it transmits a signal to the controller. The controller controls the solenoid valve to close and the control valve to open, so that the treated wastewater can be discharged through the outlet pipe.
[0019] Optionally, the stirring mechanism includes a first horizontal shaft and a second horizontal shaft, both of which are rotatably connected to the inner cavity of the processing chamber. The second horizontal shaft is located above the first horizontal shaft. A plurality of first stirring blades are connected to the top and bottom of the first horizontal shaft, and a plurality of second stirring blades are connected to the top and bottom of the second horizontal shaft. The plurality of first stirring blades and second stirring blades are arranged alternately in sequence.
[0020] By adopting the above technical solution, the first horizontal shaft rotates, driving the first stirring blade to rotate, and the second horizontal shaft rotates, driving the second stirring blade to rotate, thereby stirring the medicine and wastewater, making them fully mixed, and thus accelerating the reaction speed of the wastewater.
[0021] Optionally, the transmission mechanism includes a support frame installed on the right side of the processing chamber. A stirring motor is installed inside the support frame. A drive rod is installed at the power output end of the stirring motor. A drive gear is sleeved on the outer wall of the drive rod. A linkage gear is meshed at the bottom of the drive gear. A driven rod is connected to the left end of the linkage gear. The end of the driven rod away from the linkage gear is fixedly connected to the right end of the first horizontal shaft. The end of the drive rod away from the stirring motor is fixedly connected to the right end of the second horizontal shaft.
[0022] By adopting the above technical solution, when the stirring motor is working, the driving rod drives the driving gear to rotate, the driving gear drives the linkage gear to rotate, the linkage gear drives the driven rod to rotate, the driven rod drives the first horizontal shaft to rotate, and the driving rod drives the second horizontal shaft to rotate.
[0023] In summary, this utility model has at least one of the following beneficial effects:
[0024] The combination of the spraying mechanism and the transverse reciprocating mechanism enables the liquid storage tank to move back and forth, facilitating the even spraying of the liquid inside the storage tank onto the inside of the treatment chamber. The combination of the stirring mechanism and the transmission mechanism ensures that the liquid and wastewater react fully, thereby improving the wastewater treatment efficiency of the recovery tank.
[0025] With the combined use of the horizontal reciprocating mechanism and the positioning mechanism, when the filter screen needs to be disassembled, the positioning mechanism releases the fixing effect on the filter screen, making it convenient for staff to remove the filter screen from one side of the vertical plate for cleaning or replacement, thus minimizing the risk of clogging due to prolonged use.

[0036] Please refer to the attached diagram in the instruction manual. Figure 1 and Figure 2A transverse reciprocating mechanism 14 is provided at the top of the processing chamber 5. A medicine storage tank 11 is installed between the transverse reciprocating mechanisms 14. The transverse reciprocating mechanism 14 includes two sets of support plates 1404. The two sets of support plates 1404 are respectively fixedly installed on the top of the vertical plate 3 and the recovery tank body 1. A one-way threaded column 1402 is rotatably connected between the front ends of the two sets of support plates 1404. A servo motor 1401 for driving the one-way threaded column 1402 to rotate is installed on the outer side of the right support plate 1404. A threaded sleeve 1403 is screwed onto the outer wall of the one-way threaded column 1402. A smooth rod 1405 is horizontally connected between the rear ends of the two sets of support plates 1404. A movable sleeve 1406 is slidably sleeved on the outer side of the smooth rod 1405. The threaded sleeve 1403 and the movable sleeve 1406 are respectively fixedly connected to the front and rear ends of the medicine storage tank 11 on the side that is close to each other. When the servo motor 1401 is working, it drives the one-way threaded column 1402 to rotate. Under the sliding cooperation of the smooth rod 1405 and the movable sleeve 1406, the rotation of the one-way threaded column 1402 drives the threaded sleeve 1403 to move left and right. The movement of the threaded sleeve 1403 drives the liquid storage tank 11 to move back and forth, thereby evenly spraying the liquid into the inside of the treatment chamber 5, which improves the wastewater treatment efficiency.
[0037] Please refer to the attached diagram in the instruction manual. Figure 1 The top of the liquid storage tank 11 is provided with a liquid inlet 10, and the bottom of the liquid storage tank 11 is provided with a spraying mechanism 9. The spraying mechanism 9 includes a liquid guide pipe 903, which is fixedly connected to the bottom of the liquid storage tank 11. A spray base 902 is fixedly installed at the bottom of the liquid guide pipe 903, and several nozzles 901 are fixedly connected to the bottom of the spray base 902. The liquid medicine enters the interior of the spray base 902 through the liquid guide pipe 903, and the spray base 902 sprays the liquid medicine into the interior of the treatment chamber 5 through the nozzles 901, so that the liquid medicine mixes with the wastewater and reacts.
[0038] Please refer to the attached diagram in the instruction manual. Figure 1 The liquid guide pipe 903 is equipped with a solenoid valve 9031, and the liquid outlet pipe 7 is equipped with a control valve 701. A pH detector 4 is installed on the inner bottom wall of the treatment chamber 5, and a controller is installed on the right side of the recovery tank body 1. The output terminal of the pH detector 4 is electrically connected to the input terminal of the controller, and the output terminal of the controller is electrically connected to the input terminals of the solenoid valve 9031 and the control valve 701 respectively. When the pH detector 4 detects that the pH value of the electroplating wastewater in the treatment chamber 5 reaches the set pH value, it transmits a signal to the controller. The controller controls the solenoid valve 9031 to close and the control valve 701 to open, so that the treated wastewater can be discharged through the liquid outlet pipe 7.
[0039] Working principle: When in use, electroplating wastewater is added into the interior of the recycling tank body 1 through the opening at the top of the recycling tank body 1 for sedimentation. After a period of time, large particles of impurities settle inside the recycling tank body 1. As the water level rises, the wastewater after preliminary sedimentation enters the interior of the treatment chamber 5 through the transition hole 12. When the wastewater passes through the filter screen 13, it can intercept small particles of impurities in the water.
[0040] Then, the staff opens the solenoid valve 9031, and the medicine stored in the medicine storage tank 11 enters the interior of the spray holder 902 through the liquid guide pipe 903 and is sprayed downward through the nozzle 901. At the same time, the stirring motor 803 is turned on. When the stirring motor 803 is working, it drives the driving gear 805 to rotate through the driving rod 804. The rotation of the driving gear 805 drives the linkage gear 802 to rotate. The rotation of the linkage gear 802 drives the driven rod 801 to rotate. Thus, the driving rod 804 drives the second horizontal shaft 604 to rotate, and the driven rod 801 drives the first horizontal shaft 601 to rotate. When the second horizontal shaft 604 rotates, it drives the second stirring blade 603 to rotate. When the first horizontal shaft 601 rotates, it drives the first stirring blade 602 to rotate, thereby stirring and mixing the medicine and wastewater.
[0041] During the mixing process, the servo motor 1401 is turned on. When the servo motor 1401 is working, it drives the one-way threaded column 1402 to rotate. The rotation of the one-way threaded column 1402 drives the threaded sleeve 1403 to move. When the threaded sleeve 1403 moves, it drives the liquid storage tank 11 to move horizontally. When the liquid storage tank 11 moves, it drives the movable sleeve 1406 to slide left and right along the smooth rod 1405, thereby ensuring that the liquid storage tank 11 always moves back and forth left and right, so that the liquid can be evenly sprinkled inside the treatment chamber 5, improving the wastewater recycling efficiency.
[0042] When a large amount of impurities accumulate on the surface of the filter screen 13, the operator pulls up the rubber ball 1601. The rubber ball 1601 moves the sliding plate 1605 upward through the movable rod 1602, compressing the positioning spring 1603. The upward movement of the sliding plate 1605 moves the insertion rod 1606 upward until the insertion rod 1606 separates from the insertion hole 1607, releasing the fixing effect of the insertion rod 1606 on the filter screen 13. At this time, the filter screen 13 is pulled to the left until the positioning post 1501 separates from the positioning hole 1502. The filter screen 13 can then be removed from one side of the vertical plate 3 for cleaning or replacement, preventing the filter screen 13 from becoming clogged and affecting the wastewater flow rate.
[0043] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
