Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to a wastewater treatment device for photoinitiator production. Background Art

[0002] Photoinitiators are a type of compound that can absorb energy in the ultraviolet or visible light region and then produce free radicals, cations, etc., to initiate monomer polymerization and cross-linking curing. They are widely used in many fields such as photocurable coatings, inks, photoresists, etc. However, in the production process of photoinitiators, a large amount of wastewater with complex components and extremely difficult treatment will be generated. This type of wastewater not only contains high concentrations of salt, but also contains a variety of organic impurities, such as unreacted raw materials, reaction intermediates, and by-products. These organic impurities are complex and diverse in composition, some of which are highly toxic, and the biodegradability of the wastewater is poor. If it is discharged directly without effective treatment, it will cause serious pollution to the surrounding water bodies, soil and other ecological environments, destroy the ecological balance, and affect the survival and reproduction of plants and animals.

[0003] Existing wastewater treatment devices also have obvious deficiencies in terms of treatment efficiency, treatment effect, and degree of automation. Most devices are not convenient for multiple treatment of wastewater, resulting in incomplete wastewater filtration, which easily causes unqualified wastewater to be discharged, affecting the reuse of water resources. Moreover, due to the presence of a large amount of turbid and colored substances in the wastewater, it is difficult to treat. At the same time, a large number of solid particles generated in the treated wastewater are prone to precipitation, causing pipe blockage and hindering further treatment of the wastewater.

[0016] The beneficial effects of the present invention compared with the prior art are as follows:

[0017] 1. The present invention is provided with a floating object fishing component, and the core structure of the floating object fishing component includes a rotatable connecting shaft. A connecting frame is fixedly connected to the connecting shaft, and a filtering frame is detachably installed on the connecting frame. In practical applications, driven by the first rotation driving member, the connecting shaft can rotate, thereby driving the filtering frame to perform a rotational movement in the wastewater. This design enables the filtering frame to effectively fish out the suspended substances in the wastewater, realizing the preliminary separation of floating objects. More importantly, when the suspended substances accumulated in the filtering frame reach the saturation state, the user can conveniently remove the filtering frame from the connecting frame for replacement or cleaning, thereby ensuring the continuous and efficient operation of the fishing component.

[0018] 2. To further improve the treatment effect of wastewater, the present invention provides electrode plates in the precipitation chamber. The electrode plates are composed of two plate bodies respectively connected to the positive and negative poles of the power supply. When the wastewater enters the precipitation chamber, heavy metal ions will flocculate and precipitate under the action of the electric field. The electrode plates are stacked by multiple metal sheets to increase the contact area between the electrode plates and the wastewater. This physico-chemical process significantly improves the precipitation efficiency, effectively removing heavy metal ions in the wastewater. At the same time, the present invention is also equipped with a sewage pump. When the sediment accumulates to a certain extent, by starting the sewage pump, the sediment can be quickly discharged from the precipitation chamber to keep the precipitation chamber clean and operate efficiently.

[0019] 3. The present invention provides a cleaning component. The cleaning component includes a cleaning member, a water pump, and a transmission system composed of a pulley and a belt. In actual operation, the water pump pumps water into the cleaning member, and the cleaning member sprays high-pressure water jets to backwash the coarse filter screen and the fine filter screen. This backwashing method can effectively remove the clogging impurities attached to the filter screen. At the same time, driven by the second rotation driving member, the pulley rotates, and then drives the belt to move, enabling the cleaning member to move up and down. This movement method ensures that all parts of the coarse filter screen and the fine filter screen can be fully cleaned, thereby extending the service life of the filter screen and improving the efficiency of wastewater treatment.

[0020] 4. In the final purification chamber, the present invention provides multi-stage fillers including activated carbon filler, zeolite filler, and gravel filler. These fillers have their own characteristics and act together on the wastewater to achieve deep purification of the wastewater. The activated carbon filler has excellent adsorption performance and can remove organic substances and odors in the wastewater; the zeolite filler has good ion exchange capacity and can further remove metal ions in the wastewater; while the gravel filler plays a role in filtration and support, ensuring the stability and purification effect of the fillers. The design of this multi-stage filler not only improves the purification efficiency of the wastewater but also reduces the treatment cost, having significant economic and environmental benefits.

DETAILED DESCRIPTION

[0030] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] Reference Figures 1 - 8As shown, the present invention provides a wastewater treatment device for photoinitiator production, comprising a main body 1, wherein a sewage buffer chamber 11, a sedimentation chamber 12, a first filter chamber 13, a second filter chamber 14 and a final purification chamber 15 are sequentially arranged inside the main body 1 along the direction of water flow; a dosing component 2, which is arranged on one side of the main body 1 and can inject a purification liquid into the first filter chamber 13 for reacting with organic matter in the wastewater in the first filter chamber 13; an electrode plate 3, which is arranged inside the sedimentation chamber 12 and has two, wherein one electrode plate 3 is connected to the positive electrode of a power source, and the other electrode plate 3 is connected to the negative electrode of the power source; a floating The object salvaging component 4 is arranged inside the first filter chamber 13 and is used to collect floating objects floating on the wastewater surface; the filter component 5 is arranged in the second filter chamber 14 and is used to filter impurities in the wastewater again; the cleaning component 6 is arranged inside the second filter chamber 14, and there are two of them, and can remove impurities on the filter component 5; the purification component 7 is arranged inside the final purification chamber 15 and is used to perform final purification on the wastewater; the filler discharge component 8 is arranged at the bottom of the final purification chamber 15 and is used to discharge the purification component 7; the sewage discharge component 9 is arranged at the bottom of the main body 1 and is used to discharge the sediment in the sedimentation chamber 12.

[0032] The wastewater first enters the sewage buffer chamber 11, which plays a role in buffering and preliminarily regulating the wastewater flow, so that the wastewater can smoothly enter the subsequent treatment stage. Then the wastewater flows into the sedimentation chamber 12. Under the action of the electric field generated by the electrode plate 3, the ions in the wastewater move in a directional manner, causing some substances to precipitate, realizing solid-liquid separation, and the precipitate is discharged through the sewage discharge component 9. After that, the wastewater enters the first filter chamber 13, and the dosing component 2 injects the purification liquid into it, which reacts chemically with the organic matter in the wastewater to remove organic pollutants. At the same time, the floating object salvage component 4 collects floating objects floating on the surface of the wastewater. The wastewater treated by the first filter chamber 13 enters the second filter chamber 14, and the filter component 5 filters the wastewater again to remove fine suspended matter and particulate matter. The cleaning component 6 cleans the impurities on the filter component 5 in time to ensure the filtering effect. Finally, the wastewater enters the final purification chamber 15, and the purification component 7 performs the final purification of the wastewater to remove residual pollutants so that the wastewater meets the discharge or reuse standards. When the purification component 7 fails, it is discharged through the filler discharge component 8 and replaced with a new purification component 7, ensuring the continuous and stable operation of the entire wastewater treatment device.

[0033] The electrode plate 3 is formed by stacking a plurality of metal sheets to increase the contact area between the electrode plate 3 and the wastewater. This design greatly increases the contact area between the electrode plate 3 and the wastewater. Compared with a single integral electrode plate 3, the stacked structure enables the electrode plate 3 to have a larger surface area within a limited space, and can directly contact more wastewater. When direct current is passed through the electrode plate 3, the heavy metal ions aggregate and precipitate under the action of the electric field.

[0034] When direct current is applied to the electrode plate 3, a stable electric field is formed around the electrode plate 3. Under the action of the electric field, the heavy metal ions in the wastewater will move in a directional manner. According to the principle of electrochemistry, in a direct current electric field, positively charged heavy metal cations will move toward the electrode plate 3 connected to the negative pole of the power supply, and negatively charged heavy metal anions (such as some heavy metal complex anions) will move toward the electrode plate 3 connected to the positive pole of the power supply. When these heavy metal ions move to the vicinity of the electrode plate 3, due to the electrode reaction and the interaction between ions, they will gradually lose their original ionic state, aggregate and eventually precipitate.

[0035] The sewage discharge assembly 9 includes a sewage discharge pump 91 disposed at the bottom of the main body 1 , a first sewage discharge pipe 92 connected to the discharge end of the sewage discharge pump 91 , and a second sewage discharge pipe 93 connecting the sewage discharge pump 91 and the sedimentation chamber 12 .

[0036] When the sediment in the sedimentation chamber 12 needs to be discharged, the sewage pump 91 is started. After the sewage pump 91 starts working, a certain negative pressure is formed in the sedimentation chamber 12, and the sediment in the sedimentation chamber 12 is sucked into the sewage pump 91 through the second sewage pipe 93 under the action of the pressure difference. Subsequently, the sewage pump 91 lifts or transports the sucked sediment, and discharges the sediment to a designated location through the first sewage pipe 92, thereby completing the discharge process of the sediment in the sedimentation chamber 12, ensuring that the sedimentation chamber 12 can continue to work normally, and avoiding excessive accumulation of sediment that affects the wastewater treatment effect.

[0037] The floating object salvage assembly 4 includes a filter frame 42, at least two of which are used to collect floating objects in the wastewater; a connecting shaft 41, which is vertically arranged in the first filter cavity 13 and can rotate in the first filter cavity 13, and a connecting frame 411 for supporting the filter frame 42 is connected to the first filter cavity 13, and the filter frame 42 is detachably connected to the connecting frame 411. The floating object salvage assembly 4 also includes a first rotating driving member 43 for driving the connecting shaft 41 to rotate.

[0038] After the wastewater enters the first filter chamber 13, the floating object salvage assembly 4 starts to work. The first rotating drive member 43 is started to drive the connecting shaft 41 to rotate in the first filter chamber 13. When the connecting shaft 41 rotates, it drives the connecting frame 411 to rotate together, and then the filter frame 42 installed on the connecting frame 411 also rotates. During the rotation of the filter frame 42, part of the filter frame 42 will be immersed in the wastewater, intercepting and collecting the floating objects in the wastewater. As the connecting shaft 41 continues to rotate, the filter frame 42 that has collected the floating objects will gradually leave the water surface and take the floating objects out of the wastewater. When the filter frame 42 rotates to a suitable position, the staff can remove the filter frame 42 from the connecting frame 411 and clean the floating objects therein. After the cleaning is completed, the filter frame 42 is reinstalled on the connecting frame 411 to continue the salvage of the floating objects.

[0039] The dosing component 2 includes a dosing box 21, which is fixed to the side of the main body 1, and the dosing box 21 also stores a liquid medicine that can react with organic matter in the wastewater; a dosing pump 22, which is arranged at the bottom of the dosing box 21 and can pump the liquid medicine in the dosing box 21 into the first filter chamber 13, and the dosing pump 22 is connected to a connecting pipe 24, and one end of the connecting pipe 24 extends into the first filter chamber 13; an electromagnetic valve 23, which is arranged at the drug outlet end of the dosing pump 22, and is used to control the liquid medicine to enter the first filter chamber 13.

[0040] When it is necessary to perform dosing treatment on the wastewater in the first filter chamber 13, the dosing pump 22 is started, and the dosing pump 22 starts to work to extract the liquid medicine in the dosing tank 21. Under the pressure generated by the dosing pump 22, the liquid medicine is transported to the solenoid valve 23 through the connecting pipe 24. At this time, according to the pre-set program, the solenoid valve 23 is opened, and the liquid medicine passes through the solenoid valve 23 and enters the first filter chamber 13 along the connecting pipe 24 to be fully mixed with the wastewater. In the first filter chamber 13, the liquid medicine reacts chemically with the organic matter in the wastewater to remove the organic pollutants in the wastewater.

[0041] A plurality of slide grooves 141 are arranged on the inner wall of the second filter chamber 14 ; the filter assembly 5 includes a coarse filter 51 and a fine filter 52 , and the coarse filter 51 and the fine filter 52 can slide in the slide grooves 141 respectively, and the coarse filter 51 is arranged in front of the fine filter 52 .

[0042] The wastewater flows into the second filtration chamber 14 after being treated in the first filtration chamber 13. First, the wastewater passes through the coarse filter screen 51. With its relatively large pore size, the coarse filter screen 51 intercepts the larger particulate impurities in the wastewater, preventing these impurities from entering the subsequent filtration area. The wastewater that has been preliminarily filtered by the coarse filter screen 51 continues to flow towards the fine filter screen 52. The fine filter screen 52 has a smaller pore size and can further intercept the smaller particles and colloidal substances in the wastewater, performing a deep filtration of the wastewater. After being filtered by the coarse and fine filter screens, the impurity content in the wastewater is significantly reduced, and the water quality is remarkably improved.

[0043] The cleaning assembly 6 includes a cleaning member 61 which can move up and down, and a water passing groove is formed along the length direction of the cleaning member 61; a water pump 62 is arranged in the second filtration chamber 14, the water outlet end of the water pump 62 is connected with a hose 621, and one end of the hose 621 is connected with the cleaning member 61; a belt pulley 63 is arranged on the inner wall of the second filtration chamber 14 through a bracket, and a belt 631 is wound around the belt pulley 63, and one strand of the belt 631 is connected with the cleaning member 61; a second rotation driving member 632 is arranged on the bracket of the belt pulley 63, and the output end of the second rotation driving member 632 is connected with the belt pulley 63.

[0044] When it is necessary to clean the filtration assembly 5, start the water pump 62 and the second rotation driving member 632. The water pump 62 starts to work, extracts the wastewater from the second filtration chamber 14, and conveys the wastewater to the cleaning member 61 through the hose 621, so that water flows out from the cleaning member 61. At the same time, the second rotation driving member 632 is started to drive the belt pulley 63 to rotate. When the belt pulley 63 rotates, the belt 631 wound around the belt pulley 63 starts to move. Since one strand of the belt 631 is connected with the cleaning member 61, the movement of the belt 631 drives the cleaning member 61 to move up and down. During the up and down movement of the cleaning member 61, the water flow ejected from it flushes the impurities on the surface of the filtration assembly 5.

[0045] The purification assembly 7 includes gravel packing 73 arranged at the bottom of the final purification chamber 15 for intercepting impurities again; zeolite packing 72 arranged on top of the gravel packing 73 for adsorbing the impurities dissolved in the wastewater; activated carbon packing 71 is arranged above the zeolite packing 72; a water outlet pipe is also connected to the final purification chamber 15, and the water outlet pipe is arranged at the position of the activated carbon packing 71. The wastewater overflows upward from the bottom of the final purification chamber 15, and finally the wastewater is discharged from the water outlet pipe.

[0046] The wastewater enters from the bottom of the final purification chamber 15 and first comes into contact with the gravel packing 73. With its relatively large particle size and pores, the gravel packing 73 intercepts the larger particulate impurities in the wastewater, causing these impurities to remain in the gravel packing 73 layer, and initially purifying the wastewater. The wastewater that has been initially purified by the gravel packing 73 continues to flow upward and reaches the zeolite packing 72 layer. Utilizing its unique pore structure and chemical properties, the zeolite packing 72 adsorbs the dissolved impurities in the wastewater, such as heavy metal ions, ammonia nitrogen, etc., through physical adsorption and ion exchange, etc., further reducing the content of pollutants in the wastewater. Subsequently, the wastewater continues to flow upward into the activated carbon packing 71 layer. With its rich microporous structure and strong adsorption capacity, the activated carbon packing 71 adsorbs pollutants such as organic matter, odor, pigment, etc. in the wastewater, and conducts in-depth purification treatment on the wastewater. After the wastewater has been in-depth purified by the activated carbon packing 71, the water quality has reached a relatively high standard. At this time, the wastewater overflows upward to the position of the outlet pipe and is discharged from the final purification chamber 15 through the outlet pipe, completing the entire wastewater purification process. Through this purification method with multiple layers of packing, the advantages of various packings can be fully utilized to achieve comprehensive and efficient purification of the wastewater.

[0047] The packing discharge assembly 8 includes a hopper 81 which is arranged at the bottom of the main body 1 and is communicated with the final purification chamber 15; a baffle 82 which is rotatably arranged on the hopper 81 and is used to control the discharge of the purification assembly 7 from the final purification chamber 15; and a telescopic driving member 83 which is rotatably arranged on the main body 1, and the output end of the telescopic driving member 83 is movably connected to the baffle 82.

[0048] When it is necessary to replace or clean the packing in the purification assembly 7, the telescopic driving member 83 is started. The telescopic driving member 83 begins to contract, and its output end drives the baffle 82 to rotate, causing the baffle 82 to gradually open the channel between the hopper 81 and the final purification chamber 15. As the channel is opened, the activated carbon packing 71, zeolite packing 72, and gravel packing 73 in the final purification chamber 15 sequentially fall into the hopper 81 under the action of gravity. The packing accumulates in the hopper 81, and then the packing can be discharged from the main body 1 through the outlet at the bottom of the hopper 81 or other conveying devices, completing the packing discharge operation.

[0049] The above embodiments only represent one or several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
