Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to sewage treatment equipment and technology for producing wax blends. Background Art

[0002] Wastewater from formulated wax production is wastewater generated during the production process of formulated wax. Wastewater from formulated wax production usually contains pollutants such as grease, suspended matter, and organic matter. In order to ensure that the wastewater meets the discharge standards or reuse requirements, it is necessary to take treatment steps such as pretreatment, primary treatment, intermediate treatment, biological treatment, and deep treatment.

[0003] The main purpose of the primary treatment of wastewater for wax production is to remove floating oil, heavy oil and suspended matter in the wastewater by gravity. In the prior art, when removing floating oil, heavy oil and suspended matter in wastewater, the wastewater is first injected into a sedimentation tank for sedimentation. The heavy oil and large particles of suspended matter sink to the bottom of the sedimentation tank by gravity, and the small particles of suspended matter and floating oil float to the surface of the wastewater. In this process, flotation equipment is usually used. Subsequently, the suspended matter and floating oil suspended on the surface of the wastewater are removed, and then the wastewater is discharged from the sedimentation tank. The treatment of suspended matter in the wastewater is completed. However, the prior art usually uses wind pushing to remove suspended matter and floating oil suspended on the surface of the wastewater. The wind pushing method blows a large amount of suspended matter and floating oil to the sewage outlet of the sedimentation tank for removal. After discharge, some suspended matter and floating oil will remain, and the wind pushing to discharge suspended matter and floating oil is usually accompanied by the discharge of wastewater, resulting in a reduction in the amount of wastewater treated at a single time. The discharged wastewater needs to be treated again, which reduces the efficiency of wastewater treatment. Summary of the invention

In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0037] See also Figure 1-Figure 3 A wastewater treatment device for the production of modulated wax includes a treatment box 1 with a cubic structure, a protrusion is integrally formed on the upper left end of the treatment box 1, a discharge opening is opened on the upper end of the right side wall of the treatment box 1, a material guide frame 11 is installed at the discharge opening of the right side wall of the treatment box 1, and a drain pipe 12 with a valve is installed on the vertical side wall of the treatment box 1.

[0038] During specific operation, the treatment box 1 is hoisted to the working position by the existing hoisting equipment, and then the treatment box 1 is installed and fixed at the working position. Initially, the valve on the drain pipe 12 is in a closed state, and then the sewage filtered through the grid is poured into the treatment box 1 through the existing sewage pipe until the sewage liquid level in the treatment box 1 is flush with the bottom wall of the discharge opening, and then the injection of sewage is stopped, and then it is left to stand for a period of time, and the large particles of suspended matter and heavy oil in the sewage are precipitated.

[0039] See also Figure 1 The wastewater treatment equipment for the production of formulated wax also includes an air flotation device 2, which is connected to the treatment box 1 and is used to assist the floating of suspended matter in the wastewater.

[0040] See also Figure 1 , Figure 4 and Figure 8The flotation device 2 includes a plurality of air inlet pipes 21 evenly distributed horizontally and installed through any vertical side wall of the processing box 1, a plurality of nozzles 22 evenly distributed horizontally and located in the processing box 1 are installed on the upper end of the air inlet pipe 21, a plurality of the air inlet pipes 21 are installed together at one end located outside the processing box 1 and are connected to a ventilation pipe 23, and an anti-blocking mechanism 24 is commonly provided on the upper ends of the plurality of nozzles 22.

[0041] See also Figure 1 , Figure 4 and Figure 8 The anti-blocking mechanism 24 includes a plurality of anti-blocking rods 241 evenly distributed and respectively arranged above the plurality of the air inlet pipes 21, the lower ends of the anti-blocking rods 241 are in close contact with the corresponding upper ends of the plurality of the nozzles 22, two connecting strips 242 are installed between two adjacent connecting strips 242, a traction rod 243 is installed at one end of one outer anti-blocking rod 241 away from the connecting strip 242, the traction rod 243 and the corresponding anti-blocking rod 241 are vertically distributed, the end of the traction rod 243 away from the anti-blocking rod 241 slides through the corresponding vertical side wall of the processing box 1, a sealing sleeve 244 is installed on the annular surface of the traction rod 243, and the sealing sleeve 244 is fixedly connected to the inner end surface of the vertical side wall corresponding to the processing box 1.

[0042] During specific work, the ventilation pipe 23 is connected to the existing air pump before treatment, and multiple anti-blocking rods 241 are respectively located at the upper ends of the corresponding multiple nozzles 22, which effectively block the nozzles at the upper ends of the nozzles 22 to prevent suspended matter from entering the nozzles during the sedimentation process, thereby preventing the nozzles from being blocked. After the sewage has been statically settled for a period of time, the traction rod 243 is pulled, and the traction rod 243 drives the corresponding anti-blocking rod 241 to move horizontally. The multiple anti-blocking rods 241 move simultaneously through the multiple connecting strips 242, thereby removing the obstruction to the nozzles at the upper ends of the multiple nozzles 22, and then the existing air pump is started, and the air pump injects air into the ventilation pipe 23. The air in the ventilation pipe 23 enters the multiple air inlet pipes 21 respectively, and the air in the air inlet pipes 21 is ejected through the multiple nozzles 22 to form multiple bubbles. The bubbles combine with the suspended matter or oil droplets in the sewage to form a flotation body, which quickly floats to the water surface.

[0043] See also Figure 1 , Figure 4 and Figure 6 The wastewater treatment equipment for the production of modulated wax also includes a sewage discharge device 3, which is connected to the treatment box 1. The sewage discharge device 3 includes two driving mechanisms 31 respectively connected to the front and rear side walls of the treatment box 1. The driving mechanism 31 includes a sliding through hole 311 opened on the side wall of the treatment box 1. A guide rod 312 is installed in the sliding through hole 311, and an electric slider 313 is slidably connected to the guide rod 312.

[0044] During specific operation, the two electric sliders 313 are connected to the existing power supply before treatment. After the sewage is ventilated for a period of time, the two electric sliders 313 are started, and the electric sliders 313 slide back and forth on the guide rods 312 .

[0045] See also Figure 1 , Figure 4 and Figure 6 A pushing mechanism 32 is commonly connected between the two driving mechanisms 31, and the pushing mechanism 32 includes two L-shaped rods 321 respectively connected to the front and rear driving mechanisms 31. The electric slider 313 is fixedly connected to the horizontal section of the L-shaped rod 321. A cylindrical rod 322 is commonly installed at the opposite ends of the two L-shaped rods 321, and a connecting plate 323 is rotatably connected to the middle surface of the cylindrical rod 322.

[0046] During specific operation, when the two electric sliders 313 move toward the discharge opening direction, they drive the two L-shaped rods 321 to move, the two L-shaped rods 321 drive the cylindrical rods 322 to move, and the cylindrical rods 322 drive the connecting plates 323 to move.

[0047] See also Figure 1 , Figure 4 , Figure 5 and Figure 6 The pushing mechanism 32 is connected to a pushing mechanism 33, and the pushing mechanism 33 includes a pushing plate 331 connected to the connecting plate 323. The inner end surfaces of the front and rear side walls of the processing box 1 are provided with guide branches 333 for guiding the movement trajectory of the pushing plate 331. The sliding through hole 311 is located above the guide branch chain 333. The front and rear ends of the pushing plate 331 are rotatably connected with a slide rail column 332 with a torsion spring. The two slide rail columns 332 are respectively located in the two guide branches 333. The pushing mechanism 33 also includes a rotating opening 334 opened on the pushing plate 331, and a connecting column 335 is installed in the rotating opening 334. The connecting column 335 is rotatably connected to the connecting plate 323. Rectangular through holes 336 are symmetrically opened on the front and rear of the pushing plate 331, and a filter screen 337 is installed in the rectangular through hole 336.

[0048] See also Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7The guide branch chain 333 includes a first guide groove 3331 which is opened on the inner wall of the processing box 1 and has an L-shaped structure. The bending section of the first guide groove 3331 is an arc structure. The lower end of the first guide groove 3331 is provided with a second guide groove 3332 which is opened on the inner wall of the processing box 1. The structure of the second guide groove 3332 is consistent with that of the first guide groove 3331. A third guide groove 3333 which is opened on the inner wall of the processing box 1 and is in an inclined state is provided between the left end of the horizontal section of the second guide groove 3332 and the horizontal section of the first guide groove 3331. The two ends of the third guide groove 3333 are respectively connected with the first guide groove 3331 and the second guide groove 3332.

[0049] During specific operation, the filter screen 337 is an existing device with different specifications. Two filter screens 337 of corresponding specifications are selected and installed in the two rectangular through holes 336. Initially, the two slide rail columns 332 are respectively located on the horizontal sections of the two first guide grooves 3331, and the connecting plate 323 is in a horizontal state. The two slide rail columns 332 drive the push plate 331 to be in an inclined state through the torsion spring, and the sewage liquid level is located in the middle of the push plate 331. During operation, the connecting plate 323 drives the push plate 331 to move along the horizontal section of the first guide groove 3331 through the connecting column 335, and the push plate 331 pushes the suspended matter and oil stains floating on the water surface, and the sewage passes through the filter screen 337 and flows through the rectangular through hole 336, so as to avoid the sewage liquid level rising in the pushing direction of the push plate 331 during the pushing process, resulting in sewage overflow. The phenomenon of outflowing is avoided, thereby avoiding the reduction of sewage treatment volume. The push plate 331 pushes the suspended matter and oil stains to move under the guidance of the first guide groove 3331. When the push plate 331 moves to the arc bending section of the first guide groove 3331, the lower end of the push plate 331 first contacts the side wall of the treatment box 1, and then the connecting plate 323 continues to push the push plate 331. During the sliding process of the push plate 331 in the arc bending section of the first guide groove 3331 through the two slide rail columns 332, due to the blocking of the push plate 331 by the side wall of the treatment box 1, the push plate 331 gradually rotates from an inclined state to a vertical state and fits with the side wall of the treatment box 1. In this process, the push plate 331 discharges all the suspended matter and oil stains from the discharge opening, and the guide frame 11 guides the extruded suspended matter and oil stains and guides them into the existing collection equipment.

[0050] See also Figure 1 , Figure 4 and Figure 6 The pushing mechanism 32 also includes a U-shaped plate 324 with an opening facing left and an open end fixedly connected to the two vertical sections of the L-shaped rods 321. A rectangular plate 325 is installed at one end of the connecting plate 323 away from the pushing plate 331, and a return spring 326 is installed between the rectangular plate 325 and the middle section of the U-shaped plate 324.

[0051] During specific operation, the reset spring 326 is initially in a compressed state, and the reset spring 326 presses down the U-shaped plate 324, and the U-shaped plate 324 drives the connecting plate 323 to be in a horizontal state. After the push plate 331 moves to the arc bending section of the first guide groove 3331, as the push plate 331 moves, the push plate 331 drives the connecting plate 323 to rotate around the cylindrical rod 322, and the rotating connecting plate 323 drives the U-shaped plate 324 to rotate and squeeze the reset spring 326.

[0052] See also Figure 4 and Figure 7 The bending section of the second guide groove 3332 is connected to the vertical section of the first guide groove 3331, and a support plate 3334 in an inclined state is hinged at the connection point through a hinge rod with a torsion spring.

[0053] The push plate 331 is pressed against the top of the first guide groove 3331 to push the two guide rails 332. The push plate 331 is pressed against the top of the first guide groove 3331 to push the two guide rails 332. The push plate 331 is on the material plate 331, thereby preventing the suspended matter from returning to the sewage again. The push plate 331 drives the two slide rail columns 332 to move downward in the vertical section of the first guide groove 3331 and push the two stop plates 3334. The two stop plates 3334 are rotated under the force and release the obstruction to the two slide rail columns 332. The two slide rail columns 332 drive the push plate 331 to enter the bending section of the second guide groove 3332. After the slide rail columns 332 continue to move downward and separate from the stop plates 3334, the stop plates 3334 are reset by the torsion spring.

[0054] Then, the two electric sliders 313 move away from the discharge opening, and the electric slider 313 drives the push plate 331 away from the discharge opening through the pushing mechanism 32. The push plate 331 drives the two slide rails 332 to move in the bending section of the second guide groove 3332. At the same time, the two stop plates 3334 guide the two slide rails 332 so that the two slide rails 332 move to the horizontal section of the second guide groove 3332. At this time, the push plate 331 is reset to an inclined state by the torsion spring and is located below the sewage liquid surface. When the push plate 331 moves, the sewage hits a small amount of residual water on the filter screen 337. The suspended solids are washed to separate them from the filter screen 337 and float on the sewage surface again, and then discharged again, which further reduces the residual suspended solids in the sewage and improves the sewage treatment effect. When the push plate 331 drives the two slide rail columns 332 to move to the end of the horizontal section of the second guide groove 3332, the two slide rail columns 332 enter the two third guide grooves 3333, and the push plate 331 gradually moves upward through the two third guide grooves 3333 to guide the two slide rail columns 332 upward and re-enters the horizontal section of the first guide groove 3331, so as to realize the reset of the push plate 331 (such as Fig. 9 As shown), the pushing plate 331 repeats the cyclic pushing work until all the suspended matter in the sewage is discharged, the two electric sliders 313 and the air pump are closed, and then the valve on the drain pipe 12 is opened, and the treated sewage is discharged through the drain pipe 12 and moved to the next treatment position, and the treatment of the suspended matter in the sewage is completed.

[0055] In addition, the present invention also provides a process for treating wastewater for wax production, which specifically includes the following steps: S1: fix the treatment box 1 in the working position, then connect the flotation device 2 to the existing air pump, and then connect the drive mechanism 31 to the existing power supply.

[0056] S2: Pour the sewage into the treatment box 1 through the existing sewage pipe until the sewage liquid level in the treatment box 1 is flush with the bottom wall of the discharge opening, then stop injecting the sewage and let it stand for a while.

[0057] S3: Start the existing air pump, which discharges air from the air flotation device 2 and floats the fine suspended matter in the sewage.

[0058] S4: After step S3 continues for a period of time, the driving mechanism 31 is started. The driving mechanism 31 drives the pushing mechanism 33 through the pushing mechanism 32 to push the fine suspended matter on the liquid surface of the sewage so that it is discharged through the discharge opening. Then the driving mechanism 31 drives the pushing mechanism 33 to reset through the pushing mechanism 32.

[0059] S5: Repeat step S4 until all the fine suspended matter on the surface of the sewage is cleaned up, and the sewage suspended matter treatment is completed.
