Description
Technical Field
[0001] This application relates to the technical field of roll repair, and particularly to a device for concentrating tank liquid. Background Art
[0002] During electroplating, due to different plating types and electroplating processes, the wastewater generated during production mainly includes several categories such as oily wastewater, wastewater containing different complexing and refractory substances, acid-base copper-nickel-zinc wastewater, chromium-containing wastewater, and cyanide-containing wastewater.
[0003] The main components of chromium-containing wastewater are sulfuric acid and Cr 6+ , and also include a small amount of other metal ions such as Cu 2+ , Ni 2+ , Co 2+ , Fe 3+ , Zn 2+ , Fe 2+ , Cr 3+ , Ca 2+ and one or more impurities such as etc. The common treatment method for chromium-containing plating solution is membrane treatment and concentration. Due to the high concentration and high corrosiveness of the tank liquid, the membrane material is easily damaged, affecting the concentration efficiency. Utility Model Content
[0004] In order to reduce the adverse impact on the concentration efficiency, this application provides a device for concentrating tank liquid.
[0005] The device for concentrating tank liquid provided by this application adopts the following technical solution:
[0006] A device for concentrating tank liquid includes a housing. One side of the housing is plugged and fixedly connected with a liquid inlet pipe that communicates with the inside of the housing. Dilute tank liquid enters the housing through the liquid inlet pipe. The end of the liquid inlet pipe inserted into the housing is equipped with a downward-facing atomizing nozzle. The lower side of the housing is plugged and fixedly connected with a liquid outlet pipe, and an air suction component for driving the evaporation of water in the dilute tank liquid is provided on the upper side of the housing.
[0007] By adopting the above technical solution, the dilute tank liquid is introduced into the housing through the liquid inlet pipe. At this time, the atomizing nozzle at the end of the liquid inlet pipe atomizes the dilute tank liquid, thereby increasing the contact area between the dilute tank liquid and the air in the housing. At this time, the air suction component drives the air outside the housing to enter the housing and extracts the air inside the housing, thereby forming a flowing air current in the housing, facilitating the volatilization of the water in the dilute tank liquid, and then gradually forming concentrated tank liquid and flowing out through the liquid outlet pipe, facilitating the concentration of the tank liquid and reducing the adverse impact on the concentration efficiency.
[0008] Optionally, the air suction assembly includes an air suction shell installed at one end of the upper side of the housing and communicating with the inside of the housing. A plurality of uniformly distributed air inlet holes are formed in the air suction shell. At one end of the upper side of the housing away from the air suction shell, a suction pipe communicating with the inside of the housing is fixedly connected. A blower for extracting the air in the housing is installed on the suction pipe.
[0009] By adopting the above technical solution, the blower extracts the air inside the housing through the suction pipe. At this time, the air outside the housing enters the housing through the air inlet holes on the air suction shell, so that a flowing air current is formed inside the housing. And the uniformly distributed air inlet holes on the air suction shell enable the outside air to enter the housing uniformly along one end of the housing close to the air suction shell, further increasing the contact area between the air inside the housing and the atomized dilute bath solution, facilitating the volatilization of the water in the dilute bath solution, and reducing the adverse impact on the concentration efficiency.
[0010] Optionally, a receiving plate perpendicular to the height direction of the housing and located below the atomizing nozzle is fixedly connected inside the housing. The receiving plate is located above the liquid outlet pipe and a plurality of through holes are formed in the receiving plate. A filler is laid on the receiving plate, and the dilute bath solution is sprayed onto the upper side of the filler through the atomizing nozzle.
[0011] By adopting the above technical solution, the atomizing nozzle atomizes and sprays the dilute bath solution onto the upper side of the filler. At this time, the filler further increases the area of the dilute bath solution in the direction perpendicular to the height of the housing, thereby increasing the contact area between the dilute bath solution and the flowing air in the housing, enabling the water in the dilute bath solution to volatilize further. And the concentrated bath solution formed after volatilization passes through the filler and the receiving plate and moves to the bottom wall inside the housing, facilitating discharge from the housing through the liquid outlet pipe, and reducing the adverse impact on the concentration efficiency.
[0012] Optionally, a rotating shaft arranged along the width direction of the housing is rotatably connected to the upper side of one end of the housing close to the air suction shell. A plurality of sticky plates uniformly distributed along the circumferential direction of the rotating shaft are fixedly connected to the outside of the rotating shaft. A dust removal layer for adhering impurities is sleeved and fixedly connected to each sticky plate. A rotating member for driving the rotating shaft to rotate is provided inside the housing.
[0013] By adopting the above technical solution, the rotating member drives the rotating shaft to drive the sticky plates to rotate. At this time, the dust removal layer on the sticky plates contacts the air entering the housing and separates the impurities carried in the air from the air, reducing the possibility of impurity contamination of the bath solution. And when the sticky plates rotate, it further promotes air flow, facilitating the evaporation of the water in the bath solution, and reducing the adverse impact on the concentration efficiency.
[0014] Optionally, the rotating member includes a motor fixedly connected to the side wall of the housing. The motor is installed at one end of the rotating shaft and drives the rotating shaft to rotate.
[0015] By adopting the above technical solution, the motor drives the rotating shaft to drive the sticky plate to rotate, thereby facilitating the adhesion of impurities during the rotation process and reducing the possibility of impurity contamination of the bath solution.
[0016] Optionally, a maintenance opening is provided on the side of the housing away from the motor. An installation plate for blocking the maintenance opening is provided on the housing. One end of the rotating shaft away from the motor is inserted into the installation plate and rotatably connected to the installation plate. The installation plate is fixedly connected to the housing by bolts.
[0017] By adopting the above technical solution, the rotating shaft is rotatably connected to the housing through the motor and the installation plate. When the impurities adhered to the dust removal layer need to be cleaned, the installation plate is removed from the housing, and the rotating shaft is pulled out from the maintenance opening, which facilitates the cleaning of the impurities and further reduces the possibility of impurity contamination of the bath solution.
[0018] Optionally, a plurality of atomizing nozzles are provided and are evenly distributed along the cross-sectional direction of the housing. One end of the liquid inlet pipe inserted into the housing is fixedly connected to a connecting pipe arranged along the length direction of the housing. A plurality of mounting pipes perpendicular to the connecting pipe are fixedly connected and communicated on one side of the connecting pipe. The atomizing nozzles are evenly installed on the lower side of the mounting pipes and are communicated with the mounting pipes.
[0019] By adopting the above technical solution, the dilute bath solution in the liquid inlet pipe flows to each atomizing nozzle through the connecting pipe and the mounting pipe, and is sprayed onto the packing through the atomizing nozzles. Thus, while facilitating the uniform spraying of the dilute bath solution on the packing, it reduces the adverse effect of the atomizing nozzles on the contact between the flowing air and the dilute bath solution, and further reduces the adverse effect on the concentration efficiency.
[0020] Optionally, the lower side inside the housing is provided as an inclined surface that slopes downward and toward the side close to the liquid outlet pipe.
[0021] By adopting the above technical solution, the inclined surface on the bottom wall inside the housing facilitates driving the concentrated bath solution to flow to the liquid outlet pipe and discharging it through the liquid outlet pipe, which is convenient for collecting the concentrated bath solution.
[0022] In summary, the present application includes at least one of the following beneficial technical effects:
[0023] 1. The dilute bath solution is introduced into the housing through the liquid inlet pipe. At this time, the atomizing nozzle at the end of the liquid inlet pipe atomizes the dilute bath solution, thereby increasing the contact area between the dilute bath solution and the air in the housing. At this time, the air outside the housing is driven into the housing by the air suction assembly, and the air inside the housing is extracted, thereby forming a flowing air current in the housing, facilitating the volatilization of the moisture in the dilute bath solution, and then gradually forming a concentrated bath solution and flowing out through the liquid outlet pipe, which is convenient for concentrating the bath solution and reducing the adverse effect on the concentration efficiency;
[0024] 2. The atomizing nozzle atomizes the dilute trough liquid and sprays it onto the upper side of the packing. At this time, the packing further increases the area of the dilute trough liquid in the direction perpendicular to the height of the housing, thereby increasing the contact area between the dilute trough liquid and the air flowing in the housing, causing the moisture in the dilute trough liquid to further volatilize and reducing the adverse impact on the concentration efficiency.
[0025] 3. The rotating member drives the rotating shaft to drive the sticky plate to rotate. At this time, the dust removal layer on the sticky plate contacts the air entering the housing and separates the impurities carried in the air from the air, reducing the possibility of impurities contaminating the trough liquid. Moreover, when the sticky plate rotates, it further promotes air flow, facilitating the evaporation of moisture in the trough liquid and reducing the adverse impact on the concentration efficiency.

[0030] The following further describes the present application in detail with reference to the drawings.
[0031] The embodiment of the present application discloses a device for concentrating trough liquid. Refer to Figure 1 and Figure 2 , a device for concentrating trough liquid includes a vertical housing 1, and a liquid inlet pipe 2 communicating with the inside of the housing 1 is inserted and fixedly connected to one side of the housing 1. One end of the liquid inlet pipe 2 inserted into the housing 1 is fixedly connected and communicated with a horizontal connecting pipe 21 arranged along the length direction of the housing 1. The end of the liquid inlet pipe 2 is located in the middle of the connecting pipe 21, and three installation pipes 22 perpendicular to the connecting pipe 21 and evenly distributed along the length direction of the connecting pipe 21 are fixedly connected to the side of the connecting pipe 21 away from the liquid inlet pipe 2.
[0032] Refer to Figure 1 and Figure 2, five atomizing nozzles 23 which are evenly distributed and arranged downward are fixedly connected and communicated to the lower side of the installation pipe 22, and an installation pump 24 is installed on the liquid inlet pipe 2. A receiving plate 11 which is horizontal and located below the atomizing nozzles 23 is fixedly connected in the housing 1. The receiving plate 11 is located above the liquid outlet pipe 12, and a plurality of through holes 111 which are evenly distributed are formed in the receiving plate 11.
[0033] A filler (not shown in the figure) is laid on the upper side of the receiving plate 11. In the embodiment of the present application, it is set as titanium shavings. The dilute trough liquid is sprayed onto the filler through the atomizing nozzles 23. A liquid outlet pipe 12 is inserted and fixedly connected to the lower side of the housing 1, and the bottom wall inside the housing 1 gradually slopes downward in the direction close to the liquid outlet pipe 12. An air suction assembly 3 for driving the air flow inside the housing 1 is arranged on the upper side of the housing 1.
[0034] The dilute trough liquid is introduced into the housing 1 through the liquid inlet pipe 2 by the installation pump 24. The dilute trough liquid in the liquid inlet pipe 2 flows to each atomizing nozzle 23 through the connecting pipe 21 and the installation pipe 22, and is sprayed onto the filler through the atomizing nozzles 23. At this time, the atomizing nozzles 23 atomize the dilute trough liquid, increasing the contact area between the dilute trough liquid and the air in the housing 1, and reducing the adverse influence of the atomizing nozzles 23 on the contact between the flowing air and the dilute trough liquid. The filler further increases the area of the dilute trough liquid in the direction perpendicular to the height of the housing 1. The air suction assembly 3 drives the air outside the housing 1 to enter the housing 1 and extracts the air inside the housing 1, so as to form a flowing air flow in the housing 1, facilitating the volatilization of the water in the dilute trough liquid. And the concentrated trough liquid formed after volatilization passes through the filler and the through holes 111 on the receiving plate 11 and moves to the bottom wall inside the housing 1. The inclined surface on the bottom wall inside the housing 1 drives the concentrated trough liquid to flow to the liquid outlet pipe 12 and is discharged through the liquid outlet pipe 12, completing the concentration and collection of the trough liquid.
[0035] Refer to Figure 1 and Figure 2 , the air suction assembly 3 includes an air suction housing 31 fixedly connected to the upper side outside the housing 1. The air suction housing 31 is located at one end on the upper side of the housing 1 and is arranged along the width direction of the housing 1. A plurality of uniformly distributed air inlet holes 311 are formed in the side wall of the air suction housing 31, and the lower side of the air suction housing 31 is communicated with the inside of the housing 1. An air suction pipe 32 is installed at one end on the upper side outside the housing 1 and far away from the air suction housing 31. A frame body 321 which is vertical and used for supporting the air suction pipe 32 is fixedly connected to the upper side of the housing 1, and a fan 33 for extracting the air inside the housing 1 is installed on the air suction pipe 32.
[0036] The fan 33 extracts the air inside the housing 1 through the suction pipe 32. At this time, the air outside the housing 1 enters the housing 1 through the air inlet holes 311 on the air suction housing 31, thereby forming a flowing air current inside the housing 1. The uniformly distributed air inlet holes 311 on the air suction housing 31 enable the outside air to enter the housing 1 uniformly along one end of the housing 1 close to the air suction housing 31, facilitating the volatilization of the moisture in the dilute trough liquid.
[0037] Refer to Figure 2 and Figure 3 As shown in and, at the upper end of the inner side of the housing 1 close to the air suction housing 31, a rotating shaft 4 is provided horizontally and along the width direction of the housing 1. Four dust - sticking plates 41 evenly distributed circumferentially along the rotating shaft 4 are fixedly connected to the outside of the rotating shaft 4. A dust - removing layer 411 for adhering impurities is sleeved and fixedly connected to each of the dust - sticking plates 41. In the embodiment of the present application, it is set as a dust - removing sticky cloth.
[0038] An inspection opening 13 adapted to the rotating shaft 4 and the dust - sticking plates 41 is provided on one side of the housing 1. An installation plate 5 for blocking the inspection opening 13 is provided on the housing 1. The installation plate 5 is fixedly connected to the housing 1 by bolts. One end of the rotating shaft 4 close to the inspection opening 13 is inserted into the installation plate 5 and rotatably connected to the installation plate 5, and the other end passes through the side wall of the housing 1 and is rotatably connected to the housing 1. A rotating member for driving the rotating shaft 4 to rotate is provided on the side of the housing 1 away from the inspection opening 13. In the embodiment of the present application, the rotating member is set as a motor 42 fixedly connected to the side wall of the housing 1 and installed at one end of the rotating shaft 4 away from the inspection opening 13.
[0039] The motor 42 drives the rotating shaft 4 to drive the dust - sticking plates 41 to rotate. At this time, the dust - removing layer 411 on the dust - sticking plates 41 contacts the air entering the housing 1 and separates the impurities carried in the air from the air, reducing the possibility of impurity contamination of the trough liquid. Moreover, when the dust - sticking plates 41 rotate, it further promotes air flow, facilitating the evaporation of the moisture in the trough liquid.
[0040] The rotating shaft 4 is rotatably connected to the housing 1 through the motor 42 and the installation plate 5. When the impurities adhered to the dust - removing layer 411 need to be cleaned, the installation plate 5 is removed from the housing 1, and the rotating shaft 4 is pulled out from the inspection opening 13, facilitating the cleaning of the impurities.
[0041] The implementation principle of the device for concentrating tank liquid in the embodiments of this application is as follows: The dilute tank liquid flows through the liquid inlet pipe 2 to each atomizing nozzle 23 and is sprayed onto the packing material. Atomization increases the contact area between the dilute tank liquid and the air in the housing 1. The packing material further increases the area of the dilute tank liquid in the horizontal direction. The fan 33 extracts the air inside the housing 1 through the air suction pipe 32. At this time, the air outside the housing 1 enters the housing 1 through the air inlet holes 311 on the air suction housing 31, thereby forming a flowing air current inside the housing 1, facilitating the volatilization of the water in the dilute tank liquid. The concentrated tank liquid formed passes through the packing material and the through holes 111 on the receiving plate 11 and moves to the bottom wall inside the housing 1. The inclined surface on the bottom wall inside the housing 1 drives the concentrated tank liquid to flow to the liquid outlet pipe 12 and is discharged through the liquid outlet pipe 12, completing the concentration and collection of the tank liquid.
[0042] The above are all the preferred embodiments of this application. The protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
