Description

Technical Field

[0001] The invention belongs to the technical field of sludge treatment and relates to a barreled agglomerated sludge unloading device. Background Art

[0002] The main sludge treatment methods include landfill, brick making, incineration, etc. Sludge incineration is the most thorough treatment method. Currently, the most recommended method is to mix sludge with coal to make sludge water-coal slurry for incineration. This thorough sludge treatment eliminates the need for sludge drying and fully utilizes the energy calorific value of a large amount of organic matter in the sludge.

[0003] The reason why chemical synthesis pharmaceuticals cause serious pollution is that the synthesis process is relatively long and there are many reaction steps. The extracts in each process only account for a very small amount of raw material consumption, often only a few percentage points, while auxiliary raw materials account for the vast majority of raw material consumption. Most of these raw materials are converted into "three wastes", so the "three wastes" are produced in large quantities, the waste composition is complex, and the pollution hazards are serious. Pharmaceutical sludge has complex composition, not only containing a large amount of difficult-to-degrade organic matter, but also containing toxic and harmful substances, and the environmental risk is high; how to properly handle it has become one of the environmental issues that have received much attention. Among the many types of sludge treatment, industrial sludge with high heavy metal content and pharmaceutical factory sludge are more difficult to treat. The main components of wastewater generated at different stages of pharmaceutical factories are different, and the quality of wastewater generated by the production of different drugs is also different. Therefore, the final sludge composition is different, which is not easy to control. A large part of it is hazardous waste sludge. Therefore, it is currently very difficult to treat pharmaceutical sludge.

[0004] Since the raw materials of chemical synthetic pharmaceuticals are mainly organic substances such as sugars and starches, and multiple processes require heating, the pharmaceutical sludge coming off the machine has extremely high viscosity and will quickly agglomerate and be difficult to separate, which increases the difficulty of treating pharmaceutical sludge. At present, the pharmaceutical sludge coming off the machine is packed in disposable plastic barrels and sent to sludge treatment sites for unified treatment. There is currently no good way to treat sludge at sludge treatment sites. Simple traditional tools can only be used to cut and hit the sludge clumps together with the plastic barrels, and then crush them separately, which is time-consuming and labor-intensive. The treatment site is dirty and smelly, the working environment is extremely bad, the treatment cost is high, and the treatment effect is very poor. Therefore, the treatment of pharmaceutical sludge is currently a major technical problem in the pharmaceutical industry and the sewage sludge treatment industry. There is a lack of effective treatment technology, and the untreated pharmaceutical sludge will have adverse effects on the environment. Summary of the invention

Figure 7 , Figure 8 As shown in the figure, 8 clamping cylinders 27 are set on the outer baffle strips of the outer channel steel bars. Each station has 2 clamping cylinders 27. When the barrel arrives at each station, the telescopic head of the cylinder supports the outer functional frame of the barrel, while the inner functional frame is blocked by the inner baffle strips, thereby clamping the barrel in place. Figure 5 , Fig. 9 As shown, the upper bucket platform is equipped with multiple active long rollers 30, a positioning baffle 31 is set on the opposite side of the forklift upper bucket, and a barrel positioning cylinder 32 and a position sensor are set on the right side of the upper bucket platform. The upper bucket platform is driven by an explosion-proof motor acceleration and reduction gear, and driven by a chain. The double drive sprocket is equipped with an overrunning clutch, and the conveyor provides manual remote control start and limit switch stop functions. Figure 5 , Fig.10 As shown, the barrel unloading platform includes two roller groups symmetrically arranged on the front and rear sides, each roller group is composed of multiple rollers 23, which are installed in the groove of a channel steel bar 24. The barrel unloading platform includes a slope section L1 and a horizontal section L2, which is convenient for forklifts to unload barrels in the horizontal section. All rollers and rollers are rubber-coated rollers to increase friction, reduce wear on the barrel 1, and reduce noise.

[0038] like Figure 5 , Fig.13 As shown, the unloading rotor mechanism above the four workstations is respectively a drilling spiral rotor 4, a triangular spiral rotor 5, a root cleaning spiral rotor 6, and a flushing rotor 7. Each unloading rotor is fixedly mounted on its rotating shaft. The rotating shafts are each equipped with a hydraulic motor 8, a reducer, a lifting hydraulic cylinder 9, a double cylindrical guide rail 10, a pressure sensor, and a displacement sensor. They are driven to rotate by the hydraulic motor 8 and to move up and down by the lifting hydraulic cylinder 9. The lifting hydraulic cylinder 9 is fixedly mounted on the upper end of the main frame. A water spray port is provided above each unloading rotor. Each water spray port can be provided on the main frame to spray water to the unloading rotor in operation and the sludge in the barrel where the unloading rotor is located. Fig.13As shown, the spiral of the drilling spiral rotor 4 is a constant-diameter spiral with a diameter close to the diameter of the barrel bottom hole 2; the outer diameter of the upper end of the spiral of the triangular spiral rotor 5 is close to the inner diameter of the barrel wall, and the outer diameter of the lower end is close to the diameter of the barrel bottom hole 2; the spiral of the root cleaning spiral rotor 6 is a constant-diameter spiral with a diameter close to the inner diameter of the barrel wall; the cleaning rotor 7 is provided with at least two fan-shaped window-frame cleaning frames evenly distributed along the circumference of the axis, and a wire brush is provided on the outside of the cleaning frame.

[0039] like Figure 5 , Figure 8 As shown, a receiving bin 28 is arranged below the unloading platform, and two crushers are symmetrically arranged below the receiving bin 28 as crushing devices; the receiving bin 28 is V-shaped, and its upper end receives the bottom holes 2 of each barrel 1 located on the workbench, and two discharge holes are symmetrically opened at the lower end to connect the feed ports of the two crushers; the receiving bin 28 is provided with a heating pipe, which is heated by hot water. The crusher is preferably a vertical slurry crusher manufactured by the applicant Ningbo Lingzhi Machinery Technology Co., Ltd., see Chinese patent document CN110142109A for details.

[0040] like Figure 5 , Figure 6 As shown, the material storage pumping device includes a material storage box and a slurry delivery pump arranged next to it, the discharge port of each crusher is connected to the material storage box, and the inlet of the slurry delivery pump is connected to the bottom of the material storage box.

[0041] like Fig.12 As shown, the barreled agglomerated sludge unloading device of the present invention is composed of surrounding stainless steel wall panels, inspection doors, automatic inlet and outlet doors, hydraulic motor flexible shields, material receiving bins, etc. to form a closed space, and the top seal of the barrel divides the working space into upper and lower areas to prevent materials and wastewater from contaminating the periphery of the barrel.

[0042] During the working process of the barreled agglomerated sludge unloading device of the present invention, each water spray port is connected to the water source, and the barrels 1 filled with sludge are placed on the upper barrel platform in turn by a forklift. It should be noted that the barrels 1 need to be placed by the positioning baffle 31 and the positioning cylinder 32 to achieve the set positioning requirements. Each barrel 1 is driven by the active long roller 30 to move to the right in turn. Before moving to the first station, it encounters the opening vertical rod 18. The opening vertical rod 18 moves the inner rod 17 of the angle ruler rotating rod 14 at the bottom of the barrel 1 in motion, and the angle ruler rotating rod 14 rotates, and the barrel bottom cover 3 is opened. When entering the station section, it is driven by two groups of rollers symmetrically arranged on the front and rear sides of the main frame, and stays at each station for a set time. The stay time at each station is realized by the two clamping cylinders 27 at the station to realize the positioning and clamping of the barrel 1. When staying at the first station, the drilling spiral rotor 4 drills through the barreled sludge under water spray to form a perforated hole with a diameter equivalent to the bottom hole of the barrel. When it stops at the second station, the triangular spiral rotor expands the perforation under water spray, forming a V-shaped hole with the upper outer diameter close to the inner diameter of the barrel wall and the lower outer diameter close to the barrel bottom hole. When it stops at the third station, the root cleaning spiral rotor expands the V-shaped hole under water spray to knock down the remaining sludge. When it stops at the fourth station, the cleaning rotor 7 cleans the inner wall of the barrel and flushes the inner wall and bottom wall of the barrel with spray water to prepare for next reuse. The shape changes during the unloading process of barreled sludge are as follows Fig.14 As shown. All the unloaded sludge and the spray water are passed through the receiving bin 28 to form slurry, then enter the crusher for crushing, and then enter the storage box for temporary storage, and then transported away by the slurry delivery pump. After being treated by the barreled agglomerated sludge unloading device of the present invention, it can be mixed with coal to form sludge water-coal slurry for incineration. The sludge is treated thoroughly, the sludge drying treatment is omitted, and the energy calorific value of a large amount of organic matter in the sludge is fully utilized.
