Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a wastewater treatment device and method for cleaning nitrile gloves before demolding. Background Technology

[0002] Nitrile gloves are a type of protective glove widely used in medical, industrial, and household cleaning fields, and are favored for their excellent oil and corrosion resistance. In the production process of nitrile gloves, the cleaning step before demolding is crucial to ensure product quality. The wastewater generated during the cleaning process contains harmful chemicals such as acrylonitrile, sulfides, and ammonia nitrogen, which pose potential environmental hazards. Therefore, effective treatment is essential to ensure that the wastewater meets discharge standards.

[0003] When treating wastewater, treatment reagents are generally added to the reaction tank, and then mechanical stirring is used to mix them, which promotes the reaction between the treatment reagents and harmful chemicals in the wastewater and reduces the toxicity of the wastewater.

[0004] However, mechanical stirring is limited by the type, location, speed, and tank structure of the stirrer, which can easily lead to excessively high or low stirring intensity in certain areas. Insufficient stirring can cause uneven mixing of the treatment reagents and wastewater, resulting in excessively high or low concentrations in some areas. This can lead to a series of problems, such as uneven distribution of Fenton's reagent, where excess hydrogen peroxide can easily decompose and be wasted, and ferrous ions can easily form recalcitrant complexes with organic matter; uneven distribution of oxalic acid and hydrogen peroxide can lead to oxalic acid easily reacting with metal ions to form oxalate precipitates, and hydrogen peroxide easily oxidizing organic matter into organic peroxides; uneven distribution of potassium permanganate can easily over-oxidize organic matter into recalcitrant organic acids, or react with chloride ions to produce toxic chlorine gas. These problems increase the difficulty of treatment, reduce efficiency, and even pose safety hazards. Summary of the Invention

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for illustrative purposes and do not represent the only implementation.

[0050] Please refer to Figures 1-11 In the embodiments of the present application, a wastewater treatment device for cleaning before demolding of nitrile glove includes a support 1 and a cylinder 2 provided on the support 1, and further includes:

[0051] The first disc body 3, the second disc body 4 and the third disc body 5 are distributed from top to bottom in the cylinder 2, the first disc body 3 and the second disc body 4 are provided in the cylinder 2, the upper part of the first disc body 3 forms a premixing area, and the second disc body 4 and the third disc body 5 form a liquid storage area for storing wastewater;

[0052] The third disc body 5 is sealingly and slidingly attached to the inner wall of the cylinder 2 and can be driven by a power mechanism installed on the support 1 to move upward in the cylinder 2, and the wastewater in the liquid storage area is discharged onto the first disc body 3;

[0053] The follower pipe 15 is provided in the premixing area and is connected with a scraper 24 capable of synchronous rotation, the scraper 24 can perform flattening treatment on the wastewater on the first disc body 3 to form a thin liquid layer on the first disc body 3;

[0054] The spray head 27 is connected with the follower pipe 15 and is used for spraying treatment reagent to the surface of the thin liquid layer, the scraper 24 can also scrape the wastewater and the treatment reagent on the first disc body 3, and a plurality of transfer mechanisms provided on the cylinder 2 are used to pump the wastewater and the treatment reagent into the bottom of the cylinder 2.

[0055] It should be noted that the cylinder 2 is also provided with a liquid inlet (not shown in the figure) communicating with the liquid storage area, in actual work, the wastewater with treatment is introduced into the liquid storage area through the liquid inlet, and a gas valve is further provided at the upper part of the cylinder 2, which is used to control the pressure inside the cylinder 2 during the work of the device;

[0056] Secondly, the processing agent is not specifically limited in the present application, and can be selected according to actual needs.

[0057] Please refer again to Figure 3 With Figure 4 , a gap is reserved between the first disc body 3 and the second disc body 4, and the center of the two is fixedly connected with a communication pipe 6, the communication pipe 6 is communicated with the liquid storage area, and the upper end is flush with the annular protrusion 301 formed on the first disc body 3, so that the annular liquid tank is formed on the first disc body 3;

[0058] The power mechanism includes a hydraulic cylinder 30 arranged on the support 1 and a stand column 31 fixedly connecting the movable end of the hydraulic cylinder 30 and the third disc body 5, the stand column 31 penetrates the first disc body 3 and the second disc body 4, and is sealingly and slidingly connected with the first disc body 3 and the second disc body 4.

[0059] Further, in working, the movable end of the hydraulic cylinder 30 is intermittently elongated, so that the third disc body 5 is driven to intermittently rise in the cylinder body 2 through the stand column 31, and the wastewater in the liquid storage area is lifted every time the third disc body 5 rises, so that the wastewater flows out from the upper end of the communication pipe 6 and falls into the annular liquid tank formed by the communication pipe 6 and the annular protrusion 301 on the first disc body 3;

[0060] Then, the follow-up pipe 15 and the scraper 24 rotate, and the scraper 24 can spread the wastewater concentrated near the communication pipe 6 to all directions, so that the wastewater forms a thin liquid layer in the annular liquid tank;

[0061] The nozzle 27 will spray the processing agent on the thin liquid layer, so that the processing agent reacts with the wastewater in the thin liquid layer;

[0062] The present application sets the first disc body 3, the second disc body 4 and the third disc body 5 in the cylinder body 2, uses the third disc body 5 to send the wastewater to the first disc body 3, and uses the scraper 24 to form a thin liquid layer on the first disc body 3, so as to effectively increase the contact area of the wastewater and the processing agent, so that the processing agent can be more uniformly mixed with the wastewater, and the thoroughness of wastewater treatment is ensured, and the wastewater in the thin liquid layer is beneficial to the more rapid and uniform dispersion of the processing agent in the wastewater, so that the processing agent can more rapidly contact and react with the harmful substances (such as acrylonitrile and sulfide) in the wastewater, thereby accelerating the overall processing speed.

[0063] In addition, by controlling the elongation amount of the movable end of the hydraulic cylinder 30 each time, the amount of wastewater on the first disc body 3 can be accurately controlled, and correspondingly, by controlling the spraying amount of the nozzle 27, the proportion control of the wastewater and the processing agent can be realized, which can effectively avoid the problem of reagent waste while ensuring the processing effect.

[0064] Please refer to Figure 10 With Figure 11 The length direction of the scraper 24 is perpendicular to the axial space of the communication pipe 6, and the two ends of the scraper 24 are respectively in sealing sliding fit with the outer wall of the communication pipe 6 and the inner wall of the annular protrusion 301. The scraper 24 is connected to the follower pipe 15 through a plurality of elastic members, and the follower pipe 15 is further connected to a driving member installed in the cylinder 2.

[0065] Please refer to the accompanying Figure 11 When the third disc 5 rises, the wastewater flowing out of the upper end of the communication pipe 6 is difficult to be evenly distributed in the annular liquid holding groove by its own flow. To this end, since the length direction of the scraper 24 is perpendicular to the axial space of the communication pipe 6, when the wastewater is spread and the wastewater in the annular liquid holding groove is scraped with the treatment reagent, the driving member drives the follower pipe 15 to drive the scraper 24 to rotate clockwise in the annular liquid holding groove through the elastic members, and the scraper 24 can drive the wastewater in a direction away from the communication pipe 6.

[0066] Specifically, when the wastewater is spread, there is a gap between the bottom of the scraper 24 and the first disc 3, so as to form a thin liquid layer in the annular liquid holding groove.

[0067] After the spraying of the treatment reagent is completed, the follower pipe 15 drives the scraper 24 to move downward, the elastic members store elastic potential energy, the gap between the bottom of the scraper 24 and the first disc 3 is eliminated, and the scraper 24 rotates clockwise, so as to drive the wastewater and the treatment reagent in a direction away from the communication pipe 6, so that the transfer mechanism transfers the wastewater and the treatment reagent to the bottom of the cylinder 2.

[0068] It should be pointed out that a sufficient space is reserved between the third disc 5 and the bottom wall of the cylinder 2 in advance, and this part of the space forms a mixing area. After the wastewater and the treatment reagent are transferred to the mixing area by the transfer mechanism, further mixing treatment is performed. Specifically, stirring blades are arranged in the mixing area, and details are not described herein.

[0069] Please refer to Figure 10 The driving member includes a driving motor 12 installed on the cylinder 2 and a stand pipe 14 connected to the output end of the driving motor 12. The stand pipe 14 is in sealing sliding fit with the follower pipe 15, and the follower pipe 15 is rotatably installed with a transmission sleeve 16. The inner wall of the cylinder 2 is hinged with a gas cylinder 17, and the movable end of the gas cylinder 17 is hinged with the transmission sleeve 16. A strip-shaped protrusion 1401 is formed on the outer wall of the stand pipe 14, and a strip-shaped groove 1501 is arranged on the inner wall of the follower pipe 15.

[0070] In detail, the strip-shaped protrusion 1401 and the strip-shaped groove 1501 are parallel to the central axis of the stand pipe 14 and the follower pipe 15.

[0071] Specifically, the driving motor 12 drives the stand pipe 14 to rotate, so that the stand pipe 14 drives the follower pipe 15 to rotate through the strip-shaped protrusion 1401 and the strip-shaped groove 1501, and the follower pipe 15 drives the scraper 24 to rotate in the annular liquid tank through a plurality of elastic members, so that the wastewater near the communication pipe 6 which is difficult to spread around by itself is driven, and finally a thin liquid layer is formed in the annular liquid tank, the contact area with the treatment reagent is increased, and the reaction rate is accelerated.

[0072] After the treatment reagent is sprayed on the thin liquid layer, the movable end of the air cylinder 17 is elongated, so that the follower pipe 15 is driven to slide downward on the stand pipe 14 through the transmission sleeve 16, correspondingly, the height of the scraper 24 is lowered, until the elastic member stores elastic potential energy, the gap between the bottom of the scraper 24 and the first disc body 3 is eliminated, and the scraper 24 can drive the wastewater and the treatment reagent away from the communication pipe 6, so as to facilitate the transfer mechanism to transfer the wastewater and the treatment reagent to the bottom of the barrel 2.

[0073] Please refer to Figure 10 , the follower pipe 15 is fixedly connected with an assembly arm 20, the elastic member includes a guide cylinder 21 arranged on the assembly arm 20 and a telescopic column 22 slidably sleeved with the guide cylinder 21, a spring 23 is arranged in the guide cylinder 21, two ends of the spring 23 are connected with the first end of the telescopic column 22 and the inner wall of the guide cylinder 21 respectively, and the tail end of the telescopic column 22 is fixed with the scraper 24.

[0074] During the process that the movable end of the air cylinder 17 is elongated and the follower pipe 15 is driven to slide downward on the stand pipe 14 through the transmission sleeve 16, the scraper 24 will contact the first disc body 3, and with the continuous sliding of the follower pipe 15, the guide cylinder 21 and the telescopic column 22 will relatively slide, so that the spring 23 is compressed, and then under the elastic support of the spring 23, the tightness between the scraper 24 and the first disc body 3 can be ensured, so that when the scraper 24 rotates, the wastewater and the treatment reagent on the first disc body 3 can be effectively driven, and the problem of accumulation of the wastewater and the treatment reagent on the first disc body 3 is avoided.

[0075] Please refer to Figure 8 , Figure 10 and Figure 11, the first disc body 3 is provided with a plurality of through holes 302 equidistantly along the circumference, and the transmission sleeve 16 is connected with a plurality of groups of follow-up structures capable of switching the through holes 302 between the open and closed states; the follow-up structure comprises a branch arm 18 fixedly connected to the transmission sleeve 16 and a sealing element 19 arranged at the end of the branch arm 18 away from the transmission sleeve 16, and the sealing element 19 is matched with the through holes 302.

[0076] The wastewater and the treatment reagent in the annular liquid tank need to be discharged through the through holes 302, so that when the transfer mechanism transfers the wastewater and the treatment reagent to the bottom of the cylinder 2, the movable end of the air cylinder 17 is elongated, the follow-up pipe 15 is driven to slide downward on the stand pipe 14 through the transmission sleeve 16, correspondingly, the branch arm 18 drives the sealing element 19 to move downward, and then the sealing element 19 is separated from the through holes 302, so that the through holes 302 are open, and the cooperation of the scraper 24 and the surface of the first disc body 3 in the state of being kept in close contact and rotating can drive the wastewater and the treatment reagent to the through holes 302, so that the wastewater and the treatment reagent are discharged to the transfer mechanism through the through holes 302.

[0077] Further, the branch arm 18 is arranged in an “L” shape and is in sliding connection with the first disc body 3, and the through holes 302 are located at the position of the annular liquid tank away from the communication pipe 6 and close to the annular protrusion 301.

[0078] Please refer again to Figure 5 and Figure 7 , the transfer mechanism comprises a receiving hopper 7 arranged in the gap between the first disc body 3 and the second disc body 4, and the receiving hopper 7 is communicated with a containing cylinder 8 arranged on the outer wall of the cylinder 2.

[0079] The cylinder 2 is also provided with a pump body 9, the water inlet of the pump body 9 is communicated with the containing cylinder 8, the water outlet is connected with an arc-shaped pipe 10, adjacent two arc-shaped pipes 10 are communicated, and the arc-shaped pipes 10 are communicated with the cylinder 2 through a conduit 11, and the pump body 9 can pump the liquid in the containing cylinder 8 into the chamber between the third disc body 5 and the bottom wall of the cylinder 2 through the arc-shaped pipes 10 and the conduit 11.

[0080] Specifically, the position of the receiving hopper 7 corresponds to the position of the through holes 302, and when the through holes 302 are open, the wastewater and the treatment reagent on the first disc body 3 will be discharged to the receiving hopper 7 through the through holes 302 under the action of the scraper 24, and then flow into the containing cylinder 8, and when the amount of liquid in the containing cylinder 8 reaches a certain amount, the pump body 9 works to pump the liquid into the cylinder 2 through the arc-shaped pipes 10 and the conduit 11 for further mixing and treatment until the required reaction time is reached.

[0081] When the wastewater and the treatment reagent pass through the arc-shaped pipe 10, the wastewater and the treatment reagent are diverted and the flow state is changed due to the guiding effect of the wall of the arc-shaped pipe 10, centrifugal force and rotational flow effect are generated, which is helpful to further mix the treatment reagent and the wastewater, strengthen the mass transfer process, and make the reactants contact and react more fully.

[0082] Please refer again to Figure 9 With Figure 10 The follower pipe 15 is fixedly connected with a follower arm 25, a sliding block 26 is slidably arranged on the follower arm 25, and the spray head 27 is arranged on the sliding block 26. The sliding block 26 is connected with a sliding cooperation structure. When the follower pipe 15 drives the follower arm 25 to rotate, the sliding cooperation structure can drive the sliding block 26 to drive the spray head 27 to move along the radial direction of the first disc body 3. The spray head 27 is connected with the follower pipe 15 and the vertical pipe 14 through the telescopic bellows 28. The sleeve pipe 13 is also sealingly and rotatably arranged on the vertical pipe 14. The sleeve pipe 13 is connected with the liquid inlet pipe 1301 and is connected with the vertical pipe 14 through a plurality of liquid inlets 1402 which are equidistantly distributed in the circumferential direction of the vertical pipe 14.

[0083] When working, the treatment reagent can be pumped into the vertical pipe 14 and the follower pipe 15 through the liquid inlet pipe 1301, the sleeve pipe 13 and the liquid inlets 1402. Then, the treatment reagent can reach the spray head 27 through the telescopic bellows 28 and be sprayed onto the thin liquid layer in the annular liquid tank by the spray head 27, so that the treatment reagent and the wastewater are more fully mixed, the reaction completeness is improved, and the effect of wastewater treatment is improved.

[0084] The sliding cooperation structure includes a limiting disc 29 fixed with the support arm 18 and a protruding column 2601 arranged on the sliding block 26. The bottom of the limiting disc 29 is provided with a groove body matched with the protruding column 2601. The protruding column 2601 extends into the groove body and is slidably connected with the limiting disc 29. The groove body includes a plurality of V-shaped grooves 2901 equidistantly distributed in the circumferential direction and an arc-shaped groove 2902 connecting adjacent two V-shaped grooves 2901.

[0085] During the spraying process of the treatment reagent, the follower pipe 15 drives the follower arm 25 to rotate, so that the spray head 27 makes circumferential motion above the annular liquid tank. During this process, the protruding column 2601 slides along the V-shaped groove 2901 and the arc-shaped groove 2902. When the protruding column 2601 passes through the V-shaped groove 2901, the protruding column 2601 and the limiting disc 29 are slidably matched, so that the sliding block 26 drives the spray head 27 to move in the length direction of the follower arm 25 (i.e. the radial direction of the first disc body 3). In combination with the circumferential motion of the spray head 27, it can be ensured that the spraying of the treatment reagent can cover the entire annular liquid tank.

[0086] It should be noted that the V-shaped groove 2901 and the arc-shaped groove 2902 have a certain depth. Before the treatment reagent is sprayed, the cylinder 17 will drive the transmission sleeve 16 to rise an appropriate distance, so that there is some space between the bottom of the scraper 24 and the thin liquid layer to accommodate the treatment reagent. If the scraper 24 maintains its original height, as the treatment reagent is added, the scraper 24 will rotate, causing the treatment reagent to be driven away from the connecting pipe 6, thereby reducing the contact area between the treatment reagent and the thin liquid layer, resulting in uneven distribution of the treatment reagent on the surface of the thin liquid layer.

[0087] As another embodiment of the present invention, a wastewater treatment method for washing nitrile gloves before demolding is also proposed, using the aforementioned treatment device, including the following steps:

[0088] Step 1: Pass the wastewater to be treated into the storage area;

[0089] Step 2: The power mechanism drives the third disc 5 to rise, and the scraper 24 rotates, so that a thin layer of wastewater is formed on the first disc 3.

[0090] Step 3: The scraper 24 is raised and the nozzle 27 sprays the treatment reagent onto the surface of the thin liquid layer;

[0091] Step 4: The scraper 24 moves down and comes into contact with the surface of the first disc 3. The scraper 24 scrapes the wastewater and treatment reagent off the first disc 3, and the transfer mechanism pumps the wastewater and treatment reagent into the bottom of the cylinder 2.

[0092] Step 5: Wastewater and treatment reagents enter the bottom of cylinder 2 and are mixed until the reaction is complete.

[0093] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0094] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
