Description

Technical Field

[0001] The present invention relates to the technical field of waste liquid treatment equipment, and in particular to an environmentally friendly electroplating post-treatment equipment. Background Art

[0002] Electroplating is a process that uses chemical methods to decorate, protect and acquire certain new properties on metal and non-metal surfaces. Before electroplating, the dirt on the surface of the coating is thoroughly cleaned so that the plated part has a smooth surface and is firmly bonded to the base layer. After plating, the attached liquid on the surface of the coating is rinsed clean, which will produce a large amount of electroplating wastewater.

[0003] There are currently many ways to treat electroplating wastewater, among which flotation is a common method for treating electroplating wastewater. It mainly introduces air into the wastewater and uses tiny bubbles precipitated from the water as carriers of pollutants. Pollutants such as oil and tiny suspended particles in the wastewater float to the water surface through bubbles, thereby achieving the purpose of separating impurities. Therefore, it is applicable to environmental protection requirements.

[0004] However, in actual use, when the tiny bubbles precipitate and carry away pollutants such as oil and tiny suspended particles in the water, the bubbles stir the water flow, which makes it difficult for some heavier tiny heavy metal particles to settle to the bottom of the pool. As a result, they are easily brought to the water surface by the bubbles and further scraped away by the scraper together with the floating flocs. This will not only reduce the metal recovery rate, but also easily cause secondary pollution to the environment during the subsequent treatment of the floating flocs due to the presence of more heavy metals in the floating flocs.

[0005] In response to the above problems, Figure 2 As shown, the Chinese invention patent with patent number CN111018165B discloses an electroplating wastewater treatment device, comprising a tank body 100 and an isolating ring 110 arranged on the inner wall of the tank body 100 and cooperating with the tank body 100 to form an annular open groove structure, the isolating ring 110 is provided with a drain pipe 120 for discharging the treated electroplating wastewater, and an isolating pipe 130 arranged coaxially with the isolating ring 110 is connected to the isolating ring 110 through a bracket, and a pipe 130 is provided at one end of the isolating pipe 130 toward the bottom of the tank body 100 for separating dissolved air from the electroplating wastewater. The mixing assembly 140 for mixing and discharging water guides the bubbles precipitated in the water through the collecting plate 150. During this process, the bubbles come into contact with the collecting plate 150, so that the heavy metal particles can be separated from the bubbles and settled. A guide plate 180 is positioned on the collecting plate 150, and the collecting plate 150 can further guide the heavy metal particles from the isolation ring 110 or the isolation plate 170 to the bottom of the tank 100 for collection. While accelerating the sedimentation of the flocs, it can also effectively avoid the presence of a large amount of heavy metal components in the floating flocs, which may lead to the problem of secondary pollution when treating the floating flocs.

[0006] However, when the above-mentioned electroplating wastewater treatment device is actually used: metal particles are easy to clog in the through holes on the isolation ring 110 and the isolation tube 130, and it is inconvenient to clean and unclog these places (once clogged, the operation of the entire equipment needs to be stopped, and these places need to be cleaned and unclogged manually with a handheld nozzle or soft rod); and the above-mentioned scheme cannot adjust the angle of the collection plate 150 in time for different batches of wastewater with different concentrations, and has poor applicability. Summary of the Invention

[0007] The embodiment of the present application solves the technical problems in the prior art of the electroplating wastewater treatment device, such as the opening for conveying metal particles is easily clogged and difficult to clean, and the poor applicability caused by the inability to adjust the angle of the collecting plate, by providing an electroplating environmentally friendly post-processing equipment. The technical effect of the opening for conveying metal particles in the electroplating environmentally friendly post-processing equipment being easy to clean and having strong applicability is achieved.

[0023] Preferably, when the upper ring group of the plate expands, one or two of the annular rubber bags in the lower ring group of the plate that are closest to the isolation ring shrink, so that the lower soft plate of the wall-adhering guide ring body forms an annular pit near the isolation ring, so that the floating bubbles can stay in the pit for a short time, thereby preventing the bubbles from floating up quickly when the wall-adhering guide ring body is deformed, affecting the sewage treatment effect.

[0036] Preferably, when treating wastewater, the adsorption electromagnet is controlled to be frequently turned on and off so that the end of the wall-adhering guide ring body close to the adsorption electromagnet swings, thereby breaking up the flocs flowing to the edge of the wall-adhering guide ring body, thereby obtaining a better separation effect.

[0037] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

The delivery holes 131 are arranged in a circular pattern on the side walls of the isolation tube 130 and the isolation ring 110. The delivery holes 131 in the same row are of equal height. The number of rows of delivery holes 131 on the isolation tube 130 is greater than or equal to one, and the number of rows of delivery holes 131 on the isolation ring 110 is greater than or equal to two.

[0057] like Figure 3 As shown, the collection guide assembly includes a wall-adhering guide ring 210, a tube-adhering guide ring 220, and a medium pumping assembly 230; the number of the wall-adhering guide ring 210 is greater than 1, the number of the tube-adhering guide ring 220 is greater than 2, and the wall-adhering guide ring 210 and the tube-adhering guide ring 220 are alternately arranged;

[0058] The outer edge of the wall-adhering guide ring 210 is fixed on the isolation ring 110 and is annular. The overall cross section is in the shape of an "eight", and the left and right halves of the overall cross section are approximately acute-angled triangles.

[0059] The wall-adhering guide ring body 210 includes a supporting annular plate 211, an upper soft plate 212, a lower soft plate 213 and a shaping expansion and contraction ring group 214;

[0060] The supporting annular plate 211 is an annular hard plate body, the outer ring of which is fixed on the side wall of the isolation ring 110, and the cross section is an "eight" shape, which plays the role of supporting, positioning and shaping the expansion and contraction ring group 214;

[0062] The upper soft plate 212, the lower soft plate 213 and the isolation ring 110 together form a closed annular space, which is normally in a negative pressure state (the internal pressure is lower than the standard atmospheric pressure);

[0063] like Figure 4 As shown, the shaping expansion and contraction ring group 214 is a combination of multiple annular rubber bags, including an upper plate ring group 215 and a lower plate ring group 216; the upper plate ring group 215 includes three or more annular rubber bags of different diameters, which are positioned on the top surface of the supporting annular plate 211 and abut against the lower surface of the upper soft plate 212; the lower plate ring group 216 also includes three or more annular rubber bags of different diameters, which are positioned on the bottom surface of the supporting annular plate 211 and abut against the upper surface of the lower soft plate 213; the axes of all supporting annular plates 211 coincide.

[0064] The basic structure and deformation principle of the tube-adhering guide ring body 220 are the same as those of the wall-adhering guide ring body 210. Its cross section is in the shape of an inverted figure eight and is fixed to the side wall of the isolation tube 130. The left and right halves of the overall cross section are both approximately acute-angled triangles. The tube-adhering guide ring body 220 includes an inverted support annular plate, an inverted upper soft plate, an inverted lower soft plate, and an inverted shaping expansion and contraction ring group. The inverted support annular plate is an annular hard plate body, the inner ring of which is fixed to the side wall of the isolation tube 130. The cross section is in the shape of an inverted figure eight, which serves to support and position the inverted shaping expansion and contraction ring group.

[0065] The inverted upper soft plate and the inverted lower soft plate are both soft plates made of polyvinyl fluoride (PTFE), and both are annular plates; the cross-sections of the inverted upper soft plate and the inverted lower soft plate are both in the shape of an inverted "eight", the inverted upper soft plate is located above the inverted support annular plate, the inner ring is fixed to the side wall of the isolation tube 130, and the edge of the outer ring is fixed together with the edge of the outer ring of the inverted lower soft plate; the fixing point of the inverted upper soft plate on the isolation tube 130 is located below the conveying through hole 131 close to the inverted upper soft plate, and the edge of the inverted upper soft plate coincides with the edge of the conveying through hole 131; the inverted lower soft plate is located below the inverted support annular plate, and the inner ring is fixed to the side wall of the isolation tube 130; the distance between the fixing point of the inverted upper soft plate on the isolation tube 130 and the fixing point of the inverted lower soft plate on the isolation tube 130 is greater than 10 cm;

[0066] The inverted upper soft plate, the inverted lower soft plate and the isolation tube 130 together form a closed annular space, which is in a negative pressure state under normal conditions;

[0067] The inverted shaping expansion and contraction ring group is a combination of multiple annular rubber bags, including an inverted plate upper ring group and an inverted plate lower ring group; the inverted plate upper ring group includes three or more annular rubber bags of different diameters, which are positioned on the top surface of the inverted support annular plate and abut against the lower surface of the inverted upper soft plate; the inverted plate lower ring group includes three or more annular rubber bags of different diameters, which are positioned on the bottom surface of the inverted support annular plate and abut against the upper surface of the inverted lower soft plate; the axes of all the annular rubber bags coincide.

[0068] The main body of the medium pumping assembly 230 is a combination of a pump, a valve and a delivery pipe. Under the control of the control unit, the amount of medium in each annular rubber bag is controlled, thereby controlling the expansion and contraction of each annular rubber bag, thereby shaping the collection guide assembly.

[0069] Preferably, the medium pumped by the medium pumping component 230 is gas or water.

[0070] Preferably, the medium in the partial annular rubber bag is air, and the medium in the partial annular rubber bag is water.

[0071] Preferably, the conveying through hole 131 is an arc-shaped through groove, and the length direction is perpendicular to the height direction of the tank body 100.

[0072] The lower soft plate 213 is densely covered with wavy lines, and the length direction of the lines is the same as the width direction of the lower soft plate 213. These lines are used to guide the movement direction of the bubbles.

[0073] The power assembly is used to provide power for the operation of various components of the electroplating environmentally friendly post-processing equipment of this application, and the control unit plays a role in controlling the coordinated operation of various components of the electroplating environmentally friendly post-processing equipment. Both are existing technologies and will not be described in detail here.

[0074] Preferably, the control unit is a combination of a programmable logic controller and control buttons.

[0075] When treating wastewater (for the sake of convenience, only the use process of the wall-attached guide ring 210 is given here. The use process of the tube-attached guide ring 220 is similar to that of the wall-attached guide ring 210 and is not described in detail here):

[0076] The bubbles come into contact with the collection guide assembly, allowing the heavy metal particles to separate from the bubbles and settle;

[0077] like Figure 5 As shown, the ring group 215 on the plate expands periodically (preferably every 10 to 60 minutes) so that the particles accumulated at the conveying through hole 131 are squeezed into the conveying through hole 131, thereby avoiding clogging of the conveying through hole 131;

[0078] During use, the inclination of the lower soft plate 213 can be changed by controlling the expansion and contraction of the shaping expansion and contraction ring group 214 to obtain different wastewater treatment effects (making the bubble movement speed different).

[0079] The wall-adhering guide ring body 210 and the tube-adhering guide ring body 220 are deformed alternately.

[0080] Preferably, Figure 6 As shown, when the upper ring group 215 of the plate expands, one or two of the annular rubber bags in the lower ring group 216 closest to the isolation ring 110 shrinks, so that the lower soft plate 213 of the wall-adhering guide ring body 210 forms an annular pit near the isolation ring 110, so that the floating bubbles can stay in the pit for a short time, thereby preventing the bubbles from floating up quickly when the wall-adhering guide ring body 210 is deformed and affecting the sewage treatment effect.

[0081] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0082] The invention solves the technical problems in the prior art that the opening for conveying metal particles in the electroplating wastewater treatment device is easily clogged and difficult to clean, and the poor applicability caused by the inability to adjust the angle of the collecting plate, and achieves the technical effect that the opening for conveying metal particles in the electroplating environmentally friendly post-processing equipment is easy to clean and has strong applicability.

[0083] Example 2

[0084] Considering that the tank body 100 in the prior art and the above-mentioned embodiments needs to be disassembled regularly for relatively thorough cleaning and maintenance (curing), and even manual entry into the tank body 100 is required for cleaning and maintenance during curing, the process is complicated, labor-intensive, and takes a long time for wastewater treatment; in order to solve the above problems, the embodiment of the present application gives the tank body 100 a self-cleaning function on the basis of the above-mentioned embodiment, thereby further improving the practicality of the present application, specifically:

[0085] The supporting annular plate 211 and the inverted supporting annular plate are both made of soft rubber material;

[0086] like Figure 7 and Figure 8 As shown, the electroplating environmentally friendly post-treatment equipment also includes a liquid spray cleaning assembly 300, which is used to spray water toward the top of the wall guide ring body 210 and the tube guide ring body 220, and includes a liquid pump 310 and a water spray ring 320; the liquid pump 310 transports water to the water spray ring 320, and the water spray ring 320 is fixed to the isolation ring 110 and the isolation tube 130, and is a hollow tube body with a plurality of water ejection holes 323 densely distributed thereon; the water ejection holes 323 are through holes, all facing the top of the wall guide ring body 210 or the tube guide ring body 220;

[0087] During cleaning and maintenance, the liquid inside the tank body 100 is first emptied, and then the operation of the liquid spray cleaning component 300 is controlled while the operation of the medium pumping component 230 is controlled so that the shapes of the wall guide ring 210 and the tube guide ring 220 are continuously changed; the water column sprayed by the liquid spray cleaning component 300 falls on the wall guide ring 210 and the tube guide ring 220 to form an annular water curtain to flush the inner wall of the tank body 100.

[0088] Furthermore, the water spray ring 320 has two specifications, namely a first water spray ring 321 and a second water spray ring 322 ; the first water spray ring 321 is sleeved on the isolation tube 130 , and the second water spray ring 322 is fixed on the isolation ring 110 and is coaxial with the first water spray ring 321 .

[0089] like Figure 9 and Figure 10As shown, considering that the internal space of the isolation ring 110 and the isolation tube 130 is inconvenient to clean, in order to obtain a better cleaning effect and reduce the cleaning dead angle; preferably, the inner circle of the upper soft plate 212 is less than 5 cm away from the isolation tube 130 under normal conditions; an iron powder capsule 219 is positioned at the connection position of the upper soft plate 212 and the lower soft plate 213 in the annular space; the iron powder capsule 219 is annular and has iron powder built in; the isolation tube 130 is fixed with multiple annular adsorption devices controlled by the control unit at a position close to the upper soft plate 212 Electromagnet 132; one or more cleaning holes 111 are provided on the top of the isolation ring 110, and a sealing plug 112 is fixed to the cleaning hole 111; the cleaning hole 111 is a through hole, and the sealing plug 112 is fixed to the cleaning hole 111 in the non-cleaning state to seal the cleaning hole 111; a tube body cover 133 is positioned on the top of the isolation tube 130, and the tube body cover 133 serves to seal the isolation tube 130; each inlet and outlet channel on the tank body 100 is provided with a valve body for controlling on and off;

[0090] During the actual cleaning process: first, the liquid inside the tank body 100 is emptied, and then the medium pumping assembly 230 is controlled to operate so that the upper soft plate 212 and the lower soft plate 213 are as close to the supporting annular plate 211 as possible (at this time, the entire wall-adhering guide ring body 210 is more likely to be bent); the liquid spray cleaning assembly 300 is controlled to operate, and water is accumulated on the wall-adhering guide ring body 210. The wall-adhering guide ring body 210 is bent under the influence of water pressure and then closely adheres to the isolation tube 130; at this time, the adsorption electromagnet 132 is controlled to be energized to maintain the state of the wall-adhering guide ring body 210 being close to the isolation tube 130; and then the liquid spray cleaning assembly 300 is controlled to operate continuously. Liquid is continuously pumped into the internal space of the tank body 100 below the wall guide ring body 210, and liquid is continuously pumped into the internal space of the tank body 100 above the wall guide ring body 210; the inlet and outlet of the internal space of the tank body 100 below the wall guide ring body 210 are closed by using the valve body, the tube cover 133 and the sealing plug 112, leaving only one channel (except the delivery through hole 131), so that all liquids that need to be output in the internal space of the tank body 100 below the wall guide ring body 210 are output from this channel, and then the channel is flushed and cleaned during output; then the open channel is replaced and cleaning is continued.

[0091] Preferably, Figure 11 As shown, in the wastewater treatment state, the adsorption electromagnet 132 can be controlled to frequently switch on and off so that the end of the wall-adhering guide ring 210 close to the adsorption electromagnet 132 can swing, thereby breaking up the flocs flowing to the edge of the wall-adhering guide ring 210, thereby obtaining a better separation effect.
