Description

Technical Field

[0001] The present invention belongs to the technical field of sludge treatment, and particularly relates to a device for treating printing and dyeing wastewater sludge. Background Art

[0002] Printing and dyeing wastewater mainly comes from the printing and dyeing of cotton, hemp, chemical fibers and their blended fabrics, as well as silk and other materials, and the dyeing and finishing of wool fabrics, including wastewater discharged from multiple processes such as desizing, scouring, bleaching, mercerizing, dyeing, printing and after-finishing. These wastewaters have the characteristics of complex and diverse components, deep color, strong alkalinity, difficult biochemical treatment and significant water quality fluctuations. There are a wide variety of pollutants in printing and dyeing wastewater, with complex compositions, mainly including colored wastewater containing salts and organic substances; chlorinated and brominated wastewater; organic wastewater containing slightly acidic and slightly alkaline substances; colored wastewater containing cations such as copper, lead, chromium, manganese, mercury, etc.; and organic wastewater containing sulfur. Therefore, the printing and dyeing wastewater sludge treatment device is an important part of the printing and dyeing wastewater treatment system, used to treat the sludge generated during the treatment of printing and dyeing wastewater, reduce the environmental pollution risk, and ensure that the final disposal of the sludge meets environmental protection requirements.

[0003] However, most of the existing printing and dyeing wastewater sludge treatment devices are plate-and-frame filter presses and belt filter presses. However, the plate-and-frame filter press has limited processing capacity and relatively small throughput, unable to meet the needs of large-scale sludge treatment. The dehydration effect of the belt filter press is relatively poor, and the moisture content of the treated filter cake is relatively high, usually about 85%, unable to reach the low moisture content like that of the plate-and-frame filter press, which may lead to an increase in subsequent treatment costs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a device for treating printing and dyeing wastewater sludge.

[0006] Further, the sludge treatment component includes a double-tube cylinder, a second motor is fixedly connected to one end of the double-tube cylinder, a filter cylinder is fixedly connected to the inner side of the double-tube cylinder near the second motor end, a limiting conveying cylinder is rotatably connected to the end of the filter cylinder away from the second motor, a drying cylinder is fixedly connected to the end of the limiting conveying cylinder away from the second motor, an extrusion cylinder is fixedly connected to the end of the drying cylinder away from the limiting conveying cylinder, and a plurality of partition plates are fixedly connected to the middle part of the double-tube cylinder, and the partition plates are located at the connection parts between the filter cylinder, the limiting conveying cylinder, the drying cylinder and the extrusion cylinder.

[0007] Through the above technical solution, the setting of the filter cylinder can effectively perform preliminary filtration on the sludge and remove most of the moisture and impurities therein. Subsequently, the sludge enters the limiting conveying cylinder, which further conveys and compresses the sludge. Subsequently, through the heating effect of the drying cylinder, the residual moisture in the sludge is further evaporated, which greatly reduces the moisture content of the mud cake and improves the processing efficiency. Finally, the sludge enters the extrusion cylinder, and after high-intensity extrusion, it finally forms a mud cake with extremely low moisture content, which is convenient for subsequent transportation and disposal.

[0008] Furthermore, a liquid outlet is provided at the bottom end of the double-tube barrel near the second motor, a material outlet is provided at the end of the bottom end of the double-tube barrel away from the liquid outlet, the material outlet is located in the middle of the extrusion barrel, an air intake pipe is fixedly connected to the middle of the double-tube barrel, one end of the air intake pipe is connected to the space where the drying barrel inside the double-tube barrel is located, a drying plate is installed at the middle end of the air intake pipe away from the drying barrel, an air intake fan is installed at the middle end of the air intake pipe close to the drying barrel, a filter port is provided in the middle of the filter barrel, a large spiral rod is rotatably connected to the inner side of the filter barrel, and one end of the large spiral rod is fixedly connected to the power output end of the second motor.

[0009] Through the above technical scheme, the setting of the liquid outlet allows the excess liquid generated during the filtration process to be discharged smoothly, avoiding the accumulation of liquid and ensuring the continuity and efficiency of sludge treatment. The discharge port is located in the middle of the extrusion cylinder, which is convenient for the collection and output of the mud cake. The introduction of the air intake duct provides the necessary heat source for the drying cylinder. Through the drive of the air intake fan, hot air can evenly enter the interior of the drying cylinder to heat and dry the sludge. The drying plate effectively prevents external wet air from entering the drying cylinder, ensuring the drying effect. At the same time, the filter port in the middle of the filter cylinder and the large spiral rod rotatably connected thereto, in conjunction with the drive of the second motor, can efficiently stir and filter the sludge, further improving the effect and efficiency of sludge treatment.

[0011] Through the above technical scheme, the double-port leakage plate is combined with the multi-port leakage rotating plate to form a staggered leakage, which can further refine the sludge and evenly disperse it in the synthetic pipe. At the same time, the moving sludge can drive the rotary blade rod to rotate, continuously forming staggered leakage, improving the extrusion effect, and further improving the continuity and efficiency of sludge treatment.

[0012] Furthermore, a sealing cover and a discharge plate are fixedly connected at both ends of the drying cylinder, a plurality of small spiral rods are rotatably connected between the sealing cover and the discharge plate, a plurality of the small spiral rods are fixedly connected to third gears at the through ends close to the sealing cover, a plurality of the third gears are meshingly connected to gear rings on the outer sides, the gear rings are rotatably connected to the sealing cover, a third motor is rotatably connected to the middle part of one of the third gears, a power output end of the third motor is fixedly connected to the third gear, and the third motor is fixedly connected to the limiting conveying cylinder.

[0013] Through the above technical solution, the third motor drives the third gear and the small spiral rod meshing therewith to rotate synchronously. The rotational movement of the multiple small spiral rods in the drying cylinder can not only cut the sludge and squeeze it into balls, but also assist the hot air to penetrate and dry the sludge more deeply, thereby ensuring the drying quality of the sludge, realizing dynamic treatment of the sludge during the drying process, and enhancing the practicability and treatment effect of the device.

[0014] Furthermore, the extrusion cylinder is rotatably connected with a dividing plate on both sides near one end of the drying cylinder, a servo motor is installed on the rotating end of the dividing plate, a sliding rod is slidably connected to the middle of the extrusion cylinder, a pressure plate is provided at one end of the sliding rod, and the sliding rod is slidably connected with a slide groove at one end away from the pressure plate, the slide groove is fixedly connected to the extrusion cylinder, the sliding end of the sliding rod located inside the slide groove is rotatably connected with a long pull plate, the long pull plate is rotatably connected with a short pull plate away from one end of the sliding rod, and the end of the short pull plate away from the connecting end is rotatably connected to a fourth motor, and the power output end of the fourth motor is fixedly connected to the short pull plate.

[0015] Through the above technical scheme, the servo motor drives the dividing plate to rotate, and distributes the sludge entering the extrusion cylinder, so that the sludge can be evenly distributed in the extrusion cylinder, avoiding poor treatment effect caused by sludge accumulation or uneven distribution, and the combined dividing plate is convenient for pressing the sludge. The pressing plate on the sliding rod is driven by the servo motor to slide back and forth through the linkage action of the slide groove and the long pull plate, the short pull plate and the fourth motor to squeeze the sludge, thereby further reducing the volume and moisture content of the sludge.

[0016] Furthermore, the bottom end of the treatment tank is fixedly connected to a supporting base frame, one side of the treatment tank is fixedly connected to a medicine tank, the side of the treatment tank away from the medicine tank is fixedly connected to a second inlet box, the second inlet box is connected to the interior of the treatment tank, the bottom end of the second inlet box is fixedly connected to a material guide pipe, the second inlet box is fixedly connected to the sludge treatment component through the material guide pipe, the middle part of the inner side of the treatment tank is fixedly connected to a water inlet cylinder, the bottom end of the water inlet cylinder is connected to the treatment tank, and the through end of the water inlet cylinder is fixedly connected to the main connecting pipe.

[0017] Through the above technical scheme, the medicine tank is used to store and treat the medicines required for sludge. By accurately controlling the amount of medicine added, the efficiency and quality of sludge treatment can be effectively improved. The material guide pipe serves as a bridge connecting the second inlet box and the sludge treatment component, ensuring that the wastewater can smoothly and orderly enter the treatment component for further treatment. The design of the water inlet cylinder allows the sludge to be directly injected into the treatment tank. The structure of the entire sludge treatment device is more reasonable and the functions are more complete, which can meet the needs of different printing and dyeing wastewater sludge treatment.

[0018] Furthermore, a secondary connecting pipe is fixedly connected to one side of the medicine water tank, one end of the secondary connecting pipe is opened and located at the bottom end of the medicine water tank, a pump is fixedly connected to the bottom end of the inner side of the medicine water tank, a diversion pipe is fixedly connected to the water outlet end at the top of the pump, and the diversion pipe is fixedly connected to the stirring assembly at one end away from the pump.

[0019] Through the above technical scheme, the deposition and waste of the agent in the medicine tank are avoided. The pump, as the power source for agent extraction, can adjust the agent extraction speed as needed, thereby realizing precise control of the agent dosage. The diversion pipe evenly transports the agent extracted by the pump to the stirring component for full mixing with the sludge, thereby improving the reaction efficiency between the agent and the sludge and ensuring the effect of sludge treatment.

[0020] Furthermore, the stirring assembly includes a top frame, the four top corners of the top frame are fixedly connected to the top opening of the processing tank, the top center of the top frame is fixedly connected to a first motor, the power output end of the first motor is fixedly connected to a first gear, the first gear is evenly meshed and transmission-connected with a plurality of second gears around it, the bottom ends of the plurality of second gears are respectively fixedly connected to an upper triangular rotating plate, the bottom end of the upper triangular rotating plate is rotatably connected to a plurality of cross dial plates, the bottom ends of the plurality of cross dial plates are rotatably connected to a lower triangular rotating plate, the bottom end of the lower triangular rotating plate is rotatably connected to the processing tank, the middle part of the second gear is rotatably connected to a rotating interface, the top end of the rotating interface is fixedly connected to the top frame through and through, the through end of the rotating interface is rotatably connected to a diversion pipe, the bottom end of the rotating interface is fixedly connected to a spray cartridge, the spray cartridge is located between the plurality of cross dial plates, and the upper and lower ends of the spray cartridge are rotatably connected to the upper triangular rotating plate and the lower triangular rotating plate respectively.

[0021] Through the above technical solution, when the stirring component is started, the first motor drives the first gear to rotate. Since the first gear is evenly meshed with several second gears for transmission connection, the second gears will rotate synchronously and drive the upper triangular rotating plate, the cross dial plate and the lower triangular rotating plate to move in coordination, which not only increases the uniformity of stirring, but also enables the sludge and the agent to be more fully mixed. At the same time, the spray barrel is rotatably connected to the diversion pipe through a rotating interface. As the second gear rotates, the spray barrel can evenly spray the agent in the sludge, thereby improving the utilization rate of the agent and the sludge treatment effect. In addition, the rotating connection design of the upper triangular rotating plate, the cross dial plate and the lower triangular rotating plate makes the stirring component more stable during operation, reduces the failure rate, and improves the operating efficiency of the entire treatment device.

[0022] The beneficial effects of the present invention are as follows: 1. The present invention realizes efficient treatment and low-water content output of sludge through the filter cylinder, extrusion cylinder, limiting conveying cylinder and drying cylinder in the sludge treatment component and the grouping structure therein. The filter cylinder performs preliminary filtration on the sludge to remove most of the moisture and impurities, providing a good foundation for subsequent sludge treatment. The limiting conveying cylinder further conveys and compresses the sludge to ensure that the sludge can smoothly enter the drying cylinder. The drying cylinder evaporates the residual moisture in the sludge through heating, greatly reducing the moisture content of the mud cake and improving the treatment efficiency. Finally, the sludge enters the extrusion cylinder and, after high-intensity extrusion, finally forms a mud cake with extremely low moisture content, which is convenient for subsequent transportation and disposal.

[0023] 2. The present invention integrates a stirring component with a spraying mechanism, and through the drive of a first motor, the first gear in the stirring component is evenly meshed with a plurality of second gears for transmission, thereby driving the upper triangular rotating plate, the cross plate and the lower triangular rotating plate to rotate cooperatively. This rotational motion not only enhances the stirring effect of the wastewater, but also promotes the full mixing of the sludge and the agent in the wastewater, thereby improving the treatment efficiency. At the same time, the spraying barrel evenly sprays the agent in the wastewater as the second gear rotates, ensuring that the agent can be evenly covered, increasing the degree of sludge coagulation, and further improving the sludge treatment effect.

[0036] The working principle of this embodiment is as follows: When in use, first start the pump 104, the pump 104 draws out the medicine in the medicine tank 103 through the secondary connecting pipe 109, and transports it to the spray barrel 206 in the stirring component 2 through the shunt pipe 105.

Through the action of the air inlet fan 602 and the drying plate 601, the residual moisture in the sludge is evaporated, and the evaporated moisture is discharged through the liquid outlet 309, while the dried sludge enters the extrusion cylinder 302.

[0038] In the extrusion cylinder 302, the servo motor 325 drives the material distribution plate 318 to rotate to adjust the input amount of the sludge. The fourth motor 326 drives the pressing plate 319 to strongly press the sludge through the transmission of the short pull plate 329, the long pull plate 328 and the sliding rod 320, and finally forms a mud cake with a very low water content. The mud cake is discharged through the discharge port 308 and finally falls into the sludge collection pool 5 for subsequent transportation and disposal. The wastewater generated during the extrusion process is refluxed to the liquid collection pool 4 for further treatment through the design of the sludge treatment component 3.

[0039] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
