DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0018] like Figure 1-4 As shown, one of the purposes of the present invention is to provide a cleaning agent waste liquid treatment device, including a waste liquid treatment tank 100, wherein the waste liquid treatment tank 100 is divided into an oil collecting chamber 110, a first stirring chamber 120, a second stirring chamber 130 and a reagent chamber 140 by three partitions 200, and the oil collecting chamber 110, the first stirring chamber 120, the second stirring chamber 130 and the reagent chamber 140 are connected by the three partitions 200, wherein: The first stirring chamber 120 and the second stirring chamber 130 are respectively provided with stirring components 400 for disturbing the waste liquid, and the waste liquid flowing from the oil collecting chamber 110 is separated into oil and water by the stirring components 400, and the treatment agent in the reagent chamber 140 and the precipitation of harmful components in the waste liquid are accelerated; The top of the oil collecting chamber 110 is connected to a conveying component 500 for conveying cleaning agent waste liquid and collecting oil, and the top of the oil collecting chamber 110 is also connected to an oil extraction component 300 for sucking out the oil on the surface of the waste liquid. The top of the reagent chamber 140 is connected to another conveying component 500 for conveying the treatment agent.

[0019] The present invention is specifically as follows Figure 1 As shown, in order to process the cleaning agent waste liquid and realize safe discharge or recycling of the waste liquid, first, the cleaning agent waste liquid is introduced into the oil collecting chamber 110 through a conveying assembly 500, and when the partition 200 connects the oil collecting chamber 110, the first stirring chamber 120, the second stirring chamber 130 and the reagent chamber 140, the waste liquid will flow from the oil collecting chamber 110 into the first stirring chamber 120, the second stirring chamber 130 and the reagent chamber 140 in sequence; In the initial stage, the waste liquid is input from the discharge point into the oil collecting chamber 110 through a conveying assembly 500 and is left to stand for a period of time so that the heavier impurities in the waste liquid are initially precipitated in the oil collecting chamber 110; In the oil-water separation stage, the waste liquid flows from the oil collecting chamber 110 into the first stirring chamber 120 and the second stirring chamber 130 in sequence through the partition 200. The stirring assembly 400 stirs the waste liquid in the first stirring chamber 120 and the second stirring chamber 130 synchronously, thereby increasing the contact area between water and oil, making it easier for oil molecules to escape from water molecules. Since the density of water is greater than that of oil, the oil floats on the upper surface of the waste liquid, which facilitates the subsequent suction of the floating oil by the oil pumping assembly 300 to achieve water-oil separation. In the harmful component treatment stage, the treatment agent is transported to the inside of the agent chamber 140 through another transport component 500, and the waste liquid is stirred by the stirring component 400, so that the agent in the agent chamber 140 flows into the second stirring chamber 130 and the first stirring chamber 120 in sequence for mixing, thereby accelerating the mixing effect, allowing the harmful components to be quickly precipitated under the action of the treatment agent, thereby improving the treatment efficiency, and achieving that the water resources above the precipitation layer are the treated water resources, which is convenient for subsequent recycling; For example, an alkaline reagent such as sodium hydroxide, lime, etc. is transported into the reagent chamber 140 to adjust the pH value so that the aluminum ions form aluminum hydroxide precipitates, and a precipitation layer is formed by standing. After the precipitation layer is discharged from the water resources, it can be cleaned out of the waste liquid treatment tank 100 with the help of other cleaning equipment, so that the waste liquid treatment tank 100 can be used again next time. This is something that people in the field of technology can easily think of and will not be elaborated here.

[0020] On the basis of the above, the specific structure is disclosed in detail: First, the two conveying assemblies 500 are used to convey the cleaning agent waste liquid into the oil collecting chamber 110 and the treatment agent into the reagent chamber 140. Figure 1 As shown, the structure of the conveying component 500 is further disclosed, so that the conveying component 500 at least includes a conveying pump 510 fixed on the outer wall of the waste liquid treatment tank 100, the output end of the conveying pump 510 is connected to a conveying pipe 520, the input end of the conveying pump 510 is connected to the cleaning agent waste liquid discharge end and the treatment agent storage chamber, the conveying pipe 520 is set on the outer wall of the waste liquid treatment tank 100, and is connected to the inside of the oil collecting chamber 110 through an end of the conveying pipe 520, so that the corresponding input end of the conveying pump 510 is connected to the cleaning agent waste liquid discharge end, and under the drive of the conveying pump 510, the waste liquid is discharged from the input end to the output end, and then enters the oil collecting chamber 110 along the conveying pipe 520, and the heavier impurities in the waste liquid fall Inside the oil collecting chamber 110, when the waste liquid in the oil collecting chamber 110 flows to the first stirring chamber 120, the probability of the impurities flowing with the water into the first stirring chamber 120 is reduced under the action of the impurities' own gravity, thereby achieving preliminary precipitation of the impurities. Another delivery pipe 520 is placed on the edge of the waste liquid treatment tank 100, so that the output end of the delivery pipe 520 is connected to the inside of the agent chamber 140, and its input end is connected to the treatment agent storage chamber. Driven by the delivery pump 510, the treatment agent is introduced from the input end to the output end, and then discharged into the agent chamber 140, so that the agent is mixed with the waste liquid under the action of the stirring component 400, so as to facilitate subsequent agent treatment, precipitate harmful substances in the waste liquid, and achieve chemical treatment of the waste liquid.

[0021] Then, in order to make the stirring assembly 400 assist in the separation of water and oil on the one hand, and accelerate the mixing reaction of the waste liquid and the chemical agent on the other hand, and improve the efficiency of the precipitation treatment, as shown in FIG. Figure 2 As shown, the specific structure of the stirring assembly 400 is further disclosed, so that the stirring assembly 400 at least includes a plurality of longitudinal brackets 420 installed on the top of the waste liquid treatment tank 100, and two transverse brackets 421 are installed between the tops of the plurality of longitudinal brackets 420. The transverse brackets 421 are respectively located at the tops of the first stirring chamber 120 and the second stirring chamber 130, and support brackets 422 are installed on the tops of the support brackets 422. A support plate 424 is installed on the tops of the support brackets 422; A motor 411 housing is fixedly installed on the top of the support plate 424, and the output shaft of the motor 411 rotates and penetrates the surface of the support plate 424, and is fixedly connected with a stirring rod 410. The two stirring rods 410 are respectively rotatably arranged inside the first stirring chamber 120 and the second stirring chamber 130, so that the stirring rods 410 are driven by the output shaft of the motor 411 to rotate, and the two stirring rods 410 are respectively stirred inside the first stirring chamber 120 and the second stirring chamber 130. On the one hand, it is beneficial to stir and perform oil-water separation operations, and on the other hand, it is beneficial to mix the treatment agent with the waste liquid to precipitate and separate the aluminum ions, thereby improving the utilization rate of the stirring component 400 and saving costs.

[0022] Specifically, in order to facilitate the disassembly of the transverse bracket 421, thereby adjusting the transverse position of the supporting stirring rod 410, Figure 4 As shown, a groove is provided at the bottom of the horizontal bracket 421, and the groove is plugged and matched with the surface of the vertical bracket 420; The support frame 422 adopts a telescopic structure at both ends. By lifting the horizontal support 421 upward, the groove is separated from the surface of the longitudinal support 420, and the position and spacing of the two horizontal supports 421 are adjusted so that the support frame 422 can be telescopically supported between the two horizontal supports 421, thereby changing the horizontal position of the support frame 422 and the support plate 424 with the stirring rod 410.

[0023] In order to facilitate the disassembly of the connection between the support frame 422 and the transverse support 421, thereby adjusting the longitudinal position of the stirring rod 410 and improving the stability during assembly, Figure 4 As shown, the piston rod end of the support frame 422 is fixedly connected with a bent plate 423, and the outer wall of the bent plate 423 is threadedly connected with a fastening screw 4230, and the bent plate 423 is fitted into the outer wall of the transverse bracket 421, so that the end of the fastening screw 4230 is squeezed and fitted into the transverse bracket 421, and after the fastening screw 4230 is screwed down, the bent plate 423 is lifted upward along with the support frame 422 to achieve disassembly, which is convenient for subsequent maintenance and replacement. During assembly, the piston rod of the support frame 422 extends outward until the bent plate 423 fits the outer wall of the transverse bracket 421, and then the fastening screw 4230 is screwed inwardly until its end abuts against the transverse bracket 421, which is conducive to the stable connection between the support frame 422 and the transverse bracket 421.

[0024] It is worth noting that after oil-water separation, the oil floats on the upper layer and needs to be discharged so that the water resources under the oil can be recovered, such as Figure 3As shown, the structure of the oil pumping assembly 300 is further disclosed, so that the oil pumping assembly 300 at least includes an oil pump 330, the input end of the oil pump 330 is connected to an oil pipe 331, the output end is connected to an oil storage tank, and the oil pipe 331 is set on the edge of the waste liquid treatment tank 100, when the oil inside the oil collecting chamber 110 floats on the upper layer, the oil pipe 331 is extended into the oil collecting chamber 110, and the end is inserted into the oil layer, and the oil pump 330 is driven to discharge the oil along the oil pipe 331 to the inside of the oil storage tank. The oil pipe 331 is made of a hose material and can be pulled at will to change the length of the oil pipe on the edge of the waste liquid treatment tank 100, so as to be regulated according to the depth of the oil layer to ensure that the oil is fully collected.

[0025] Specifically, although the oil collecting chamber 110, the first stirring chamber 120, the second stirring chamber 130 and the reagent chamber 140 are connected by the partition 200, the floating oil usually forms an irregular distribution, and it is necessary to constantly change the collection position to cover the oily area more evenly, thereby improving the collection efficiency and ensuring that no oil is missed, especially those gathered at the edge or inaccessible places. Therefore, again as Figure 3 As shown, the oil extraction assembly 300 also includes a slide frame 310 fixed on the outer wall of the waste liquid treatment tank 100, and a slider 320 is slidingly provided inside the slide frame 310. The top of the slider 320 is fixedly connected to a limit frame 321, and the inside of the limit frame 321 is adapted to the outer wall contour of the oil pipe 331 and penetrates through the limit, and the bottom of the slider 320 is fixedly connected to a connecting frame 322, and the outer shell of the oil pump 330 is fixed on the outer wall of the connecting frame 322, and the oil pipe 331 is inserted into the inside of the limit frame 321 to limit the position of the oil pipe 331, so that when the slider 320 slides inside the slide frame 310, it can drive the oil pipe 331 and the oil pump 330 to move together, change the position of oil extraction, and improve the oil collection effect.

[0026] The second object of the present invention is to provide a cleaning agent waste liquid treatment process, which is applied to any of the above cleaning agent waste liquid treatment equipment, comprising the following steps: S1, when the oil collecting chamber 110, the first stirring chamber 120, the second stirring chamber 130 and the reagent chamber 140 are connected by the partition 200, a conveying assembly 500 introduces the cleaning agent waste liquid into the oil collecting chamber 110, and the waste liquid flows from the oil collecting chamber 110 into the first stirring chamber 120, the second stirring chamber 130 and the reagent chamber 140 in sequence; S2, using two stirring assemblies 400 to synchronously stir the waste liquid in the first stirring chamber 120 and the second stirring chamber 130 respectively to achieve water-oil separation, and sucking out the oil on the surface of the waste liquid through the oil pumping assembly 300; S3. Another conveying component 500 conveys the treatment agent to the inside of the reagent chamber 140, and stirs the waste liquid through the stirring component 400, so that the reagent in the reagent chamber 140 flows into the second stirring chamber 130 and the first stirring chamber 120 in turn for mixing, thereby accelerating the mixing effect and allowing the harmful components to quickly precipitate under the action of the treatment agent. Example 2

[0027] In the above-mentioned embodiment 1, the oil collecting chamber 110, the first stirring chamber 120, the second stirring chamber 130 and the reagent chamber 140 are always connected by the partition 200, resulting in limited efficiency of stirring oil-water separation and stirring and mixing to produce sediment. Figure 5-Figure 8 As shown, the present embodiment is different from the embodiment 1 in that the partition 200 includes at least a partition frame 210, a flow frame 220 is slidably provided inside the partition frame 210, and telescopic fitting members 230 are provided at the top and bottom of the flow frame 220. The telescopic fitting members 230 are used to make the liquid flow only from the inside of the flow frame 220 when the flow frame 220 slides up and down to change the connection position, which is conducive to driving the flow frame 220 to slide inside the partition frame 210, changing the height of the connection between the two areas, and realizing that when the flow frame 220 is higher than the liquid level, the two areas can be disconnected; As for the driving force of the flow rack 220, an adjusting screw 221 can be rotated on the inner wall of the partition rack 210, and the convex plate on the outer wall of the flow rack 220 is threadedly connected with the adjusting screw 221. By manually driving the adjusting screw 221 to rotate, the convex plate drives the flow rack 220 to move up and down, and the height of the connection between the two areas is changed. At this time, the telescopic fitting member 230 is composed of a multi-stage sliding frame, and an elastic member is fixedly connected between two adjacent sliding frames. Through the elastic force of the elastic member, the position of the flow rack 220 can be adapted to maintain the closed partition above and below the flow rack 220 (note that the end of the sliding frame and the end of the flow rack 220 are both sealed and fitted to the inner wall of the partition rack 210 for sliding); A transfer pump 240 is provided on the top of the partition frame 210. The output end and the input end of the transfer pump 240 are respectively connected to transfer pipes 241. Driven by the transfer pump 240, the liquid in the area where the two transfer pipes 241 extend can be transferred and flowed, specifically including the following postures; Posture 1: When the first stirring chamber 120, the second stirring chamber 130 and the reagent chamber 140 are separated by the partition 200, the partition 200 of the second embodiment is provided between the oil collecting chamber 110 and the first stirring chamber 120. Before the conveying assembly 500 drives the cleaning waste liquid into the oil collecting chamber 110, the flow rack 220 between the two is raised to the highest point, that is, when the telescopic fitting member 230 at the bottom of the flow rack 220 is extended to the longest position, the cleaning waste liquid is conveyed to the oil collecting chamber 110, so that the waste liquid is only allowed to stand in the oil collecting chamber 110, so that large particles of impurities in the waste liquid are first precipitated to form an initial precipitation layer, thereby improving the standing effect and preventing water flow from affecting the initial precipitation. After the initial precipitation is completed, the flow rack 220 is driven to move downward, at least the flow rack 220 is located at the top of the initial precipitation layer, so that the waste liquid in the oil collecting chamber 110 flows from the flow rack 220 to the inside of the first stirring chamber 120. When the free flow reaches the highest value, the waste liquid on the initial precipitation layer is transported completely into the inside of the first stirring chamber 120 through the transfer pipe 241 of the transfer pump 240; Posture 2: When the oil collecting chamber 110, the first stirring chamber 120 and the medicine chamber 140 are separated by the partition 200, with respect to the partition 200 between the first stirring chamber 120 and the second stirring chamber 130, before the waste liquid flows from the oil collecting chamber 110 to the inside of the first stirring chamber 120, the flow rack 220 between the two is located at the lowest point, that is, when the telescopic fitting member 230 on the top of the flow rack 220 is extended to the longest position, the waste liquid is evenly distributed and flows in the first stirring chamber 120 and the second stirring chamber 130, and the waste liquid can also be assisted to be transported by the transfer pump 240 between the two; Then, the flow rack 220 between the two is driven to move upward to exceed the liquid surface, so that the first stirring chamber 120 and the second stirring chamber 130 are completely separated, so that the two stirring rods 410 can concentrate on stirring the waste liquid in the first stirring chamber 120 and the second stirring chamber 130, respectively, to improve the water-oil separation efficiency; Posture 3: For the partition 200 between the second stirring chamber 130 and the reagent chamber 140, during the stirring process for water-oil separation, the flow rack 220 between the two is located at the highest point, so that the second stirring chamber 130 and the reagent chamber 140 are not connected, and the reagent is transported to the inside of the reagent chamber 140 by the conveying component 500 until the water-oil separation is completed, and after the floating oil is extracted by the oil extraction component 300, the flow rack 220 is driven to move downward, so that the reagent can flow into the second stirring chamber 130. Under the stirring action of the stirring rod 410, the reagent is mixed with the waste liquid in the second stirring chamber 130 and the first stirring chamber 120 respectively, so as to improve the reaction effect of the reagent; The reagents in the second stirring chamber 130 flow directly, and the reagent concentration is relatively high, and the mixed precipitation and the formation of the aluminum ion precipitation layer have the best effect. The first stirring chamber 120 and the second stirring chamber 130 can also be blocked by the separator 200, and the waste liquid in the first stirring chamber 120 can be completely transported to the second stirring chamber 130 through the transfer pump 240 and the transfer pipe 241 to fully mix with the treatment agent. Alternatively, the waste liquid in the second stirring chamber 130 may be mixed and reacted first, and after the reaction generates a precipitate, the precipitate and separated water resources are discharged, and then the first stirring chamber 120 and the second stirring chamber 130 are connected, and the treatment agent is re-delivered for reaction to improve the quality of the chemical precipitation.
