Description

Technical Field

[0001] The utility model relates to the technical field of sludge recycling, in particular to a printing and dyeing sludge mixed fuel preparation device. Background Art

[0002] The moisture content of dyeing sludge is usually in the range of 65% to 70%. Traditionally, this sludge is dehydrated by using steam heating in a disc dryer to reach a moisture content of 50% to 55%. However, this process is often accompanied by a large amount of low-pressure steam consumption, resulting in a relatively high unit cost for drying dyeing sludge.

[0003] In order to improve energy efficiency and reduce costs, the current mixing technology directly mixes printing and dyeing sludge with combustible materials with low moisture content, which can produce mixed fuel with moisture content also controlled at 50% to 55%. This mixed fuel can not only replace the traditional disc dryer and reduce the dependence on low-pressure steam, but also further reduce the dependence on auxiliary fuels such as coal by adding fuel with a certain calorific value, thus optimizing energy consumption.

[0004] In addition, by mixing printing and dyeing sludge with biomass materials such as sawdust, waste branches, or SRF (solid recovered fuel) with high calorific value and low moisture content, it can not only meet the moisture content standard of the fuel entering the furnace, but also effectively replace the traditional thermal drying technology. The preparation of this mixed fuel significantly improves the overall calorific value of the fuel by introducing high calorific value biomass fuel or SRF, thereby reducing the dependence on auxiliary fuels such as coal and natural gas to a certain extent, and realizing the cost savings of auxiliary fuels.

[0005] In summary, this hybrid technology not only improves the efficiency of printing and dyeing sludge treatment and reduces treatment costs, but also makes positive contributions to environmental protection and sustainable development. It is an important step for the printing and dyeing industry to move towards green transformation.

The discharge hopper 7 is closed and has only one outlet located below the inclined conveyor belt 4.

[0028] The feeding module includes an inclined conveyor belt 28 and a receiving hopper 9 fixedly connected to the frame of the inclined conveyor belt 28. The horizontal height of the discharge end of the inclined conveyor belt 28 is greater than the horizontal height of the feed end. The receiving hopper 9 is located below the outlet, and the receiving hopper 9 is an annular plate structure with open top and bottom surfaces. An inverted U-shaped frame is welded on the frame of the inclined conveyor belt 28. The receiving hopper 9 is welded on the receiving hopper 9, and the cross-sectional area from the upper end opening to the lower end opening gradually decreases. The cross-section is specifically trapezoidal. The bottom surface of the receiving hopper 9 is fitted with the belt surface of the inclined conveyor belt 28, and the receiving hopper 9 is provided with an open groove 10 on the side of the receiving hopper 9 facing the discharge end of the inclined conveyor belt 28.

[0029] The mixing module includes a bracket 11, a mixing barrel 14 horizontally fixedly connected to the bracket 11, and a stirring guide assembly. The mixing barrel 14 is closed at one end and open at the other end, and the stirring guide assembly is arranged at the open end of the mixing barrel 14. An inlet groove connected to the interior of the mixing barrel 14 is arranged on the outer peripheral wall, and a receiving plate 19 located below the inlet groove is welded on the outer peripheral wall of the mixing barrel 14, and the inlet groove can be opened and closed. Specifically, the opening and closing method is that both ends of the mixing barrel 14 are fixedly connected to a mounting plate, and a cylinder 21 is fixedly connected to the mounting plate. The piston rod of the cylinder 21 is fixedly connected to a sealing door 20 arranged in contact with the outer peripheral wall of the mixing barrel 14, and the sealing doors 20 on both sides can close the inlet groove.

[0030] The cross-sectional area of ​​the closed end of the mixing barrel 14 is gradually reduced, and an outlet pipe 22 communicating with the interior of the closed end of the mixing barrel 14 is fixedly connected to the smallest cross-sectional area, and the outlet pipe 22 is connected to a valve 23.

[0032] During the actual operation of the present invention, auxiliary materials are put into the crusher 2, which will crush the auxiliary materials into a smaller volume, and then fall onto the grille 6 through the feed hopper 3. Auxiliary materials of suitable volume can pass through the grille 6 and fall onto the belt surface of the inclined conveyor belt 4, which is driven by the inclined conveyor belt 4 to rise up, and when leaving, it can be blocked by the discharge hopper 7 so that the materials can only leave through the outlet, thereby ensuring that the materials can fall into the receiving hopper 9. Since the bottom surface of the receiving hopper 9 is open, when the materials fall into it, they will eventually still contact the belt surface of the inclined conveyor belt 8, and then leave through the open slot 10 until they enter the mixing barrel 14 through the inlet slot. During the feeding process, the receiving plate 19 is The materials discharged are taken over. In addition, the printing and dyeing sludge is directly conveyed into the mixing barrel 14 through the feeding hopper 13. When the feeding amount on both sides reaches the standard, the feeding can be stopped, and then the cylinder 21 works to drive the sealing door 20 to displace in contact with the outer wall of the mixing barrel 14, thereby closing the inlet groove. At the same time, the valve 23 also needs to be closed to ensure that the outlet pipe 22 is blocked, and then the driving motor 16 drives the turntable 17 to rotate, and the reinforcing plate 18 ensures the structural strength of the turntable 17 itself. When the turntable 17 rotates, it will drive a number of threaded plates to stir the sludge and auxiliary materials therein. When its rotation speed is faster, the sludge and materials are subjected to a larger centrifugal force, thereby adhering to the inner wall of the mixing barrel 14. The setting of the threaded plates can more effectively stir these sludge and materials.

[0033] After the final thorough mixing, the valve 23 is opened and the driving motor 16 continues to work, so that it continues to generate centrifugal force on the material. Due to the threaded shape of the threaded plate, while generating centrifugal force on the material, it also generates a certain force in the direction of the outlet pipe 22. In this way, the material discharge work can be completed. Afterwards, the sealing door 20 is driven to move by the cylinder 21, and the initial action is repeated to complete the fuel production work in batches. It can achieve the effect of reusing printing and dyeing sludge, and can also be produced and processed in an integrated manner, thereby improving the overall production efficiency.
