Description

Technical Field

[0001] This utility model relates to the field of sludge treatment, and more specifically, to a high-viscosity sludge mixing and conditioning device. Background Technology

[0002] Currently, sludge dewatering systems requiring 60% sludge dewatering necessitate the addition of chemical agents to condition the sludge, altering its chemical properties before it can operate in the dewatering equipment. The sludge conditioning process involves uniformly mixing the sludge with liquid chemical agents. This is typically done by injecting the sludge and chemicals into a conditioning tank or container and then stirring them together. Sludge needs to be as fluid as a liquid to easily mix evenly with chemicals. For example, Chinese utility model patent CN211972092U discloses a multi-stage mixing process device for sludge chemical conditioning. In use, the activated carbon box purifies wastewater, allowing for reuse and improving the device's energy recycling capacity. The air pump and placement tank evenly disperse chemicals into the sludge, increasing the efficiency of chemical conditioning and reducing processing time, thus improving the device's working efficiency. Furthermore, the electric motor ensures more thorough mixing of chemicals with the sludge. The separation plate separates branches from the sludge, preventing them from entering the device and causing damage during mainboard rotation. The baffle also prevents branches from sliding down the gaps between the toothed structures at the bottom of the separation plate during collection, reducing the possibility of injury during manual collection.

[0003] In existing sludge dewatering systems, sludge conditioning requires the sludge to have a certain degree of fluidity; that is, it can only condition fluid sludge with a high water content. Non-fluid sludge with a low water content (e.g., sludge with a water content below 85%) needs to be diluted with water before conditioning and modification, and only after conditioning can the sludge undergo secondary dewatering. This method results in low process efficiency and waste of water and electricity in processing low-moisture sludge.

[0004] Therefore, it is necessary to redesign a high-viscosity sludge mixing and conditioning device to address the above-mentioned problems. Utility Model Content

[0005] To overcome the aforementioned shortcomings of the prior art, embodiments of this utility model provide a high-viscosity sludge mixing and conditioning device. The technical problem to be solved by this utility model is that existing devices can only condition and modify sludge with high water content and good flowability. If sludge with low water content, poor flowability, and high viscosity needs further dewatering, a conditioning tank cannot be used; water must be added to dilute the sludge, making it flowable again before conditioning and modification. This is time-consuming, labor-intensive, and inefficient.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-viscosity sludge mixing and conditioning device includes a box body. A bottom support plate is fixedly installed at the bottom end of the box body. A drive shaft and a driven shaft are symmetrically rotatably connected to the inner side wall of the box body. Multiple toothed blades are provided circumferentially at equal intervals on the outer walls of the drive shaft and the driven shaft. Square bearing seats are installed at both ends of the drive shaft and the driven shaft, respectively, through the inner side wall of the box body and extending outward. The square bearing seats are fixedly connected to one side of the box body. A transmission gear is fixedly connected to one end of the drive shaft and the driven shaft, and the two transmission gears mesh with each other.

[0008] In a preferred embodiment, a gear reduction motor is fixedly installed on the upper surface of the bottom support plate, and the gear reduction motor is fixedly connected to a transmission gear in a corresponding position via a coupling.

[0009] In a preferred embodiment, each of the square bearing housings is provided with a sealed bearing between itself and the housing.

[0010] In a preferred embodiment, the upper end face of the box is provided with a feed inlet.

[0011] In a preferred embodiment, the upper surface of the housing has a plurality of through holes at equal intervals, each through hole is provided with a protective cover plate above it, and each protective cover plate is provided with an observation cover plate.

[0012] In a preferred embodiment, a gearbox protective cover is fixedly installed on the upper end face of the bottom support plate, and the coupling rotates through the gearbox protective cover, with both transmission gears located inside the gearbox protective cover.

[0013] In a preferred embodiment, the bottom end of the box is provided with a discharge port, and an auxiliary adjustment plate is provided inside the discharge port.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention incorporates a drive shaft, a driven shaft, toothed blades, and a gear reducer motor. The gear reducer motor drives the transmission gears to rotate, which in turn drives the toothed blades to crush and propel the sludge in the same direction. Simultaneously, liquid or solid conditioning agents are added and dispersed by the toothed blades, uniformly mixing the agents into the semi-solid sludge to achieve conditioning and modification. This solves the problem of sludge conditioning characterized by low moisture content, poor fluidity, and high viscosity. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figure 1-2 A high-viscosity sludge mixing and conditioning device includes a box body 1. A bottom support plate 2 is fixedly installed at the bottom end of the box body 1. A drive shaft 3 and a driven shaft 4 are symmetrically rotatably connected to the inner side wall of the box body 1. Multiple toothed blades are provided circumferentially at equal intervals on the outer walls of the drive shaft 3 and the driven shaft 4. It should be noted that the toothed blades have a certain angle. Square bearings 13 are installed at both ends of the drive shaft 3 and the driven shaft 4, respectively, through the inner side wall of the box body 1 and extending outward. The square bearings 13 are fixedly connected to one side of the box body 1. A transmission gear 11 is fixedly connected to one end of the drive shaft 3 and the driven shaft 4, and the two transmission gears 11 mesh with each other.

[0021] A gear reducer motor 12 is fixedly installed on the upper end face of the bottom support plate 2. The gear reducer motor 12 is fixedly connected to the corresponding transmission gear 11 through a coupling 14.

[0022] Each square bearing 13 is provided with a sealed bearing 5 between itself and the housing 1.

[0023] The upper surface of the housing 1 is provided with a feed inlet 7, which provides a channel for the entry of high-viscosity sludge and conditioning agent. The design of the feed inlet 7 facilitates the rapid and smooth entry of materials into the housing 1, avoids material blockage or spillage during the feeding process, improves feeding efficiency, and ensures the continuity of the mixing and conditioning process.

[0024] Multiple through holes are evenly spaced on the upper surface of the chamber 1. Each through hole is topped with a protective cover 8, and each protective cover 8 is fitted with an observation cover 9. The through holes on the upper surface of the chamber 1, together with the protective cover 8 and the observation cover 9, provide operators with convenient operating and observation windows. The protective cover 8 prevents debris from falling into the chamber and also acts as a seal when no conditioning agent is added, reducing odor emissions. The observation cover 9 is made of transparent material, allowing operators to observe the mixing state of the sludge inside the chamber 1, the addition of conditioning agent, and the stirring effect at any time without opening the protective cover 8. This facilitates timely adjustments to operating parameters and ensures optimal mixing and conditioning results.

[0025] A gearbox protective cover 6 is fixedly installed on the upper surface of the bottom support plate 2, and the coupling 14 rotates through the gearbox protective cover 6. Both transmission gears 11 are located inside the gearbox protective cover 6. The gearbox protective cover 6 encloses the transmission gears 11 and the coupling 14, providing comprehensive protection for these critical transmission components. It effectively prevents external dust, debris, moisture, etc., from entering the gearbox, avoiding wear or damage to the transmission components due to contamination. At the same time, it also provides a certain degree of sound insulation and safety protection, reducing the noise generated during the operation of the device and protecting the safety of the operators.

[0026] A discharge port is provided at the bottom of the housing 1, and an auxiliary regulating plate 10 is installed inside the discharge port. The discharge port at the bottom of the housing 1 is used to discharge the conditioned sludge, while the auxiliary regulating plate 10 can flexibly control the discharge speed and flow rate of the sludge. By adjusting the position of the auxiliary regulating plate 10, the discharge volume can be precisely controlled according to the needs of subsequent processing steps, ensuring the smooth connection of the sludge treatment process and improving the operating efficiency of the entire sludge treatment system.

[0027] In use, sludge, liquid, and solid conditioning agents enter the housing 1 through the inlet 7 and fall between the drive shaft 3 and the driven shaft 4. Then, the gear reducer motor 12 on the bottom support plate 2 starts operating, transmitting power to the connected transmission gear 11 via the coupling 14. Since the two transmission gears 11 mesh, when one gear 11 rotates, it drives the other gear 11 to rotate simultaneously, thereby driving the drive shaft 3 and the driven shaft 4 to rotate respectively. When the two shafts rotate, the toothed blades on the shafts insert into the sludge, continuously cutting and breaking up the semi-solid sludge. The modified liquid agent also seeps into the semi-solid sludge along the toothed blades for conditioning and mixing. Simultaneously, the toothed blades, with a certain angle, continuously squeeze and push the sludge towards the outlet during rotation, constantly mixing it with the conditioning agent during this process, ultimately achieving a uniform mixture.

[0028] The square bearing 13 provides stable support for the drive shaft 3 and the driven shaft 4, while the sealed bearing 5 prevents impurities such as sludge from entering the bearing, ensuring smooth shaft rotation. The gearbox protective cover 6 protects the transmission gear 11 and the coupling 14 from external interference or damage, ensuring stable operation of the device.

[0029] After the sludge and conditioner are fully mixed and conditioned, the discharge speed and flow rate of the conditioned sludge can be controlled by adjusting the auxiliary regulating plate 10 in the discharge port at the bottom of the box 1, and the sludge can be transported to the subsequent treatment process.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
