Description

Technical Field

[0001] This utility model relates to the field of kitchen waste sludge mixing technology, and in particular to a mixing device for kitchen waste sludge treatment. Background Technology

[0002] Traditional methods for treating food waste and sludge are not only inefficient but also prone to causing secondary pollution. To improve treatment efficiency, reduce environmental pollution, and achieve resource utilization, it's crucial to understand that food waste and sludge contain a large amount of organic matter, which can be transformed into useful resources such as bio-fertilizers and biogases through appropriate treatment. However, food waste and sludge typically contain a high amount of moisture and have complex compositions, making direct treatment often ineffective. Therefore, pretreatment is necessary to ensure the food waste and sludge are thoroughly mixed and their physicochemical properties are adjusted to meet the requirements of subsequent treatment processes.

[0003] Most food waste and sludge mixing equipment currently on the market suffers from problems such as uneven mixing, inconvenient operation, and difficult cleaning. Cleaning is particularly problematic; due to the complex internal structure of the mixing equipment, residual substances are difficult to remove completely. This not only affects the equipment's lifespan but may also adversely impact subsequent processing. Therefore, it is necessary to propose solutions to this technical problem. Summary of the Invention

[0004] The technical problem to be solved by this utility model is that uneven mixing of kitchen waste sludge makes it difficult to clean the inside of the equipment.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a mixing device for treating kitchen waste sludge, including a mixing tank fixed on a support platform, a feeding pipe and a discharging mechanism connected to the mixing tank, a slot provided on the top of the mixing tank, a top cover for sealing the mixing tank being lifted and installed on the slot, a fastening mechanism between the top cover and the mixing tank, a stirring mechanism and a heating mechanism installed at the bottom of the top cover, and a dispensing pipe connected to the top cover.

[0006] Preferably, the fastening mechanism includes a fastening groove at the bottom of the top cover, a fastening plate that is horizontally slidably disposed in the fastening groove, an inclined groove at the top of the mixing tank, an inclined block adapted to the inclined groove on one side of the bottom of the fastening plate, and a telescopic mechanism for driving the fastening plate to move is installed on the top cover. When the telescopic mechanism is in the retracted state, the fastening plate is located on one side of the fastening groove and the inclined block is located in the inclined groove.

[0007] Preferably, a fixed box is installed on the top of the top cover, the fastening plate and the telescopic mechanism are both located inside the fixed box, an iron plate is fixedly installed on the top of the inner side of the fastening groove, and an electromagnetic lock is installed on the top of the fastening plate.

[0008] Preferably, the mixing tank is provided with lifting mechanisms on both sides, and the top of the lifting mechanism is connected to the top cover.

[0009] Preferably, the stirring mechanism includes a linkage box vertically arranged on the top cover, a stirring motor installed on the top cover, and a stirring shaft installed at the bottom of the linkage box. The stirring motor and the stirring shaft are connected by a drive through the linkage box. The stirring shaft is located below the top cover, and stirring blades are evenly arranged on the stirring shaft.

[0010] Preferably, the heating mechanism is a heating tube that is vertically fixed on the top cover, and the heating tubes are evenly distributed on both sides of the top cover.

[0011] Preferably, the discharge mechanism includes a discharge pipe connected to the bottom of the end wall of the mixing tank and a valve installed on the discharge pipe.

[0012] This utility model provides a mixing device for treating kitchen waste sludge. The mixing device supplies kitchen waste and sludge through two feed pipes, which can achieve precise material ratio and ensure full contact and uniform distribution of the two raw materials during the mixing process. By adding necessary regulators and nutrients through the feed pipe, the physicochemical properties of the mixture can be effectively improved, making it more suitable as a raw material for subsequent processing.

[0013] By using the locking and telescopic mechanisms in combination, the locking of the fastening plate can be easily released, allowing the top cover to automatically detach from the slot at the top of the mixing tank. This design greatly simplifies the cleaning process and improves work efficiency. After the top cover is opened, personnel can directly observe and rinse the inside of the mixing tank to ensure no residue remains, guaranteeing the cleanliness of the mixing tank and avoiding cross-contamination and equipment corrosion caused by residues. After cleaning, by controlling the operation of the lifting and telescopic mechanisms, the top cover can quickly reset and be firmly fixed to the top of the mixing tank, ensuring the safety and stability of the equipment operation.

[0020] Please see Figure 1-4This utility model relates to a mixing device for treating kitchen waste sludge, comprising a mixing tank 1, a support platform 2 at the bottom of the mixing tank 1, two inlet pipes 3 and a discharge mechanism on the mixing tank 1, a slot at the top of the mixing tank 1, a top cover 4 on the slot, a stirring mechanism, a heating mechanism and a dispensing pipe 5 on the top cover 4, the dispensing pipe 5 connecting to the top cover 4, fixed boxes 20 on both sides of the top cover 4, a lifting mechanism 6 between the fixed boxes 20 and the support platform 2, and a fastening mechanism between the fixed boxes 20 and the slot. The system includes a fastening groove and an inclined groove 7. The inclined groove 7 is formed on the slot, and the fastening groove is formed inside the fixed box 20, extending into the interior of the top cover 4. A through groove is formed between the fastening groove and one side of the top cover 4. A fastening plate 8 is provided on the fastening groove, and an inclined block 9 is provided on one side of the fastening plate 8, which abuts against the inclined groove 7. A telescopic mechanism 10 is provided between the interior of the fixed box 20 and the fastening plate 8, and a locking mechanism is provided between the fastening plate 8 and the fastening groove. In this embodiment, kitchen waste and sludge are supplied through two feed pipes 3, and then through a dispensing pipe. 5. Feed in ingredients, such as adjusting the pH value and adding necessary nutrients, then mix them using a stirring mechanism. A heating mechanism ensures the mixture is within a suitable temperature range for mixing. Finally, the mixed material is discharged using a discharge mechanism and sent to the next processing stage, such as an anaerobic digester or aerobic composting pile, for easy recycling. Before shutdown, any remaining material inside the mixing tank 1 needs to be cleaned. At this time, the locking mechanism in the fastening system is used to release the locking of the fastening plate 8, and then the output end of the telescopic mechanism 10 is controlled to move the fastening plate 8. The fastening plate 8 moves within the fastening groove, and the inclined block... 9. Following the movement of the fastening plate 8, the inclined block 9 leaves the inclined groove 7. Then, the two lifting mechanisms 6 are controlled to move the top cover 4 upward in sync, so that the top cover 4 automatically disengages from the slot at the top of the mixing tank 1. Personnel can easily observe and rinse the inside of the mixing tank 1 through the slot, thereby ensuring the cleanliness of the mixing tank 1 and facilitating its next use. After cleaning, the lifting mechanism 6 is controlled to reset the top cover 4, and the top cover 4 rests against the slot. At this time, the inclined block 9 is aligned with the inclined groove 7. The output end of the telescopic mechanism 10 is controlled to move the fastening plate 8, so that the inclined block 9 rests against the inclined groove 7. The downward force is generated by the tilt angle, so that the top cover 4 is more firmly fixed in the slot.

[0021] In this solution, the locking mechanism includes an iron plate 11 and an electromagnetic lock 12. The iron plate 11 is installed at the top of the fastening groove, and the electromagnetic lock 12 is installed at the top of the fastening plate 8. By opening the electromagnetic lock 12 at the top of the fastening plate 8, the electromagnetic lock 12 attracts the iron plate 11, thereby firmly fixing the fastening plate 8. By closing the electromagnetic lock 12, the electromagnetic lock 12 stops attracting the iron plate 11, thereby releasing the locked state and facilitating the use of the telescopic mechanism 10.

[0022] In this solution, the mixing mechanism includes a mixing motor 13 and a linkage box 14. Both the mixing motor 13 and the linkage box 14 are mounted on the top cover 4. The linkage box 14 extends to the bottom of the top cover 4. The output end of the mixing motor 13 is connected to the input end of the linkage box 14. The output end of the linkage box 14 is provided with a mixing shaft 15. The mixing shaft 15 is provided with a mixing blade 16. When the mixing motor 13 is turned on, the linkage box 14 drives the mixing shaft 15 to rotate. The mixing shaft 15 can drive the mixing blade 16 to rotate inside the mixing tank 1. The mixing blade 16 can quickly mix the food waste and sludge.

[0023] In this solution, the heating mechanism includes a heating tube 17, which is installed at the top of the top cover 4 and extends to the bottom of the top cover 4. The heating tube 17 heats the inside of the mixing tank 1, which facilitates the mixing of kitchen waste and sludge within a suitable temperature range.

[0024] In this scheme, multiple heating tubes 17 are provided, and the heating efficiency of the mixing tank 1 can be improved by using multiple heating tubes 17.

[0025] In this solution, the discharge mechanism includes a discharge pipe 18, which is installed at one end of the mixing tank 1. The discharge pipe 18 is equipped with a valve 19, which allows the mixed material to be discharged easily by opening the valve 19.

[0026] In this solution, both the lifting mechanism 6 and the telescopic mechanism 10 are cylinders. Cylinders have the characteristics of high movement accuracy and good stability, thereby improving the movement accuracy of the lifting mechanism 6 and the telescopic mechanism 10.

[0027] In this design, the stirring motor 13 is a servo motor, which has the characteristic of high rotational accuracy, thereby improving the rotational accuracy of the stirring motor 13.
