[0001] This utility model relates to the field of sludge treatment technology, specifically to an urban sludge treatment device that integrates belt filter press and sludge drying. Background Technology

[0002] The core of urban sludge treatment is to achieve reduction, stabilization, harmlessness, and resource utilization. The mainstream technology is mainly based on the combination of "pretreatment + end-of-pipe treatment". Resource utilization has become the core direction, such as sludge co-incineration power generation, anaerobic digestion to produce biogas, composting to produce organic fertilizer, etc. The technology is transforming towards "low carbon" to reduce energy consumption and carbon emissions in the treatment process and promote new energy-driven treatment systems.

[0003] Currently, belt filter press and drying integrated treatment devices are used in the treatment of urban sludge. In the feeding stage of the belt filter press and drying integrated treatment, the sludge itself has a high water content and high viscosity, and it is prone to agglomeration due to static settling during temporary storage and transportation. These agglomerated sludge cloggings the conical feed pipes will hinder the smooth entry of subsequent sludge and cause large fluctuations in the feed rate. This will prevent the belt filter press unit of the integrated device from fully exerting its treatment efficiency, reduce the overall treatment efficiency, and affect the use of the sludge treatment device.

[0024] 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.

[0025] Please see Figure 1-4 This utility model provides a new technical solution:

[0026] The sludge treatment integrated device 1 serves as the core of the overall treatment, integrating belt filter press and sludge drying functions. All components are assembled around it to complete the integrated treatment of sludge dewatering and drying.

[0027] The conical feed pipe 2 is fixedly connected to the upper left surface of the sludge treatment integrated device 1. It has a conical structure, with the upper end being the feed port and the lower end communicating with the inside of the integrated device. It is used to guide the sludge into the treatment device in a directional manner.

[0028] The discharge pipe 3 is fixedly connected to the right end of the front surface of the sludge treatment integrated device 1, serving as the discharge channel for the treated dry sludge and realizing the centralized collection of the treated products.

[0029] A circular hole 4 is opened on the upper surface of the conical feed pipe 2 to provide an interface for the installation of the sealing plate 8, and at the same time facilitates the subsequent maintenance of the auxiliary mechanism inside the pipe.

[0030] The rotating rod 5 is rotatably installed on the lower inner wall of the conical feed pipe 2. Its upper end is inserted into the circular groove 15 of the sealing plate 8, and its lower end is fixedly connected to the output end of the motor 7. It is used to drive the push plate 6 to rotate and transmit power.

[0031] The pusher plate 6 is fixedly connected to the outer surface of the rotating rod 5 in a ring array. As the rotating rod 5 rotates, it stirs, disperses and pushes the sludge in the conical feed pipe 2. Rectangular plates or trapezoidal plates can be selected to adapt to different sludge scenarios.

[0032] The motor 7 is fixedly installed on the lower surface of the conical feed pipe 2. The output end rotates through the inside of the pipe and is fixed to the rotating rod 5, providing power for the rotation of the rotating rod 5 and the push plate 6.

[0033] The sealing plate 8 is inserted into the inside of the circular hole 4 and fixed by the connecting screw 14. It is used to seal the upper opening of the conical feed pipe 2, and at the same time, the circular groove 15 provides limiting support for the upper end of the rotating rod 5.

[0034] The annular plate 9 is rotatably installed in the annular groove 10 on the lower inner wall of the conical feed pipe 2, and its upper end is fixedly connected to the rotating rod 5, which provides radial support for the rotating rod 5 and reduces the shaking during rotation.

[0035] The annular groove 10 is formed on the lower inner wall of the conical feed pipe 2, providing space for the installation and rotation of the annular plate 9, and working with the annular plate 9 to ensure the stable operation of the rotating rod 5;

[0036] The protective box 11 is fixedly installed on the lower surface of the tapered feed pipe 2, with an opening at the top to enclose the motor 7 inside, preventing sludge from splashing or external collisions from damaging the motor 7;

[0037] Wiring hole 12 is provided on the lower surface of protective box 11 for the wires of motor 7 to pass through, which facilitates the connection of motor 7 to power supply and reduces the risk of sludge entering the interior of protective box 11.

[0038] The connecting grooves 13 are arranged in a ring array on the upper surface of the sealing plate 8, and the lower end extends into the conical feed pipe 2 to provide an installation channel for the connecting screw 14;

[0039] The connecting screw 14 is threaded into the inside of the connecting groove 13, and the sealing plate 8 is firmly fixed to the tapered feed pipe 2 through the threaded engagement to ensure the sealing effect.

[0040] A circular groove 15 is formed on the lower surface of the sealing plate 8 and is inserted into the upper end of the rotating rod 5. It plays a role in positioning and limiting the upper end of the rotating rod 5 to prevent the rotating rod 5 from deviating when it rotates.

[0041] The handle 16 is fixedly connected to the upper surface of the sealing plate 8, providing a gripping point for the operator to disassemble the sealing plate 8, and facilitating quick opening of the circular hole 4 for inspection or cleaning.

[0042] Furthermore, the sealing plate 8 is connected to the circular hole 4 of the conical feed pipe 2 via the connecting screw 14. The upper end of the rotating rod 5 is inserted into the circular groove 15 of the sealing plate 8. The motor 7 is located inside the protective box 11 and is connected to the power supply through the wiring hole 12. The sludge enters from the upper end of the conical feed pipe 2. The motor 7 is started, and the motor 7 drives the rotating rod 5 to rotate. The four rectangular push plates 6 on the outer surface of the rotating rod 5 rotate in a ring with the rotating rod 5. During the rotation, the push plates 6 stir and push the sludge entering, so that the sludge flows evenly and quickly into the sludge treatment integrated device 1. After passing through the belt filter press and sludge drying treatment in the sludge treatment integrated device 1, the sludge is finally discharged from the discharge pipe 3. If maintenance or cleaning is required, the connecting screw 14 can be unscrewed through the handle 16 to remove the sealing plate 8 and maintain the inside of the conical feed pipe 2 and the push plates 6.

[0043] The motor 7 drives the rotating rod 5 to rotate, causing the rectangular pusher plate 6 to rotate with the rotating rod 5. This stirs and pushes the sludge, breaking up sludge clumps, reducing feeding resistance, and allowing the sludge to enter the treatment device quickly, thus improving feeding efficiency. The annular array distribution and rotational motion of the pusher plate 6 make the sludge more evenly distributed in the conical feed pipe 2, ensuring the stability of subsequent pressure filtration and drying treatments, thereby improving the performance of the sludge treatment device.

[0044] Example 1 (for reference) Figure 3 )

[0045] When the pusher plate 6 is a rectangular plate, the planar structure of the rectangular pusher plate forms a uniform shearing and pushing force on the sludge when rotating, which can quickly break up the flocculent clumps in the sludge and make the sludge enter the belt filter press and drying integrated device in a uniform fluid state. Its regular shape is also easy to process and manufacture.

[0046] Example 2 (for reference) Figure 4 )

[0047] When the pusher plate 6 is a trapezoidal plate, the inclined side design of the trapezoidal pusher plate has a guiding effect on pushing the sludge during rotation, which can concentrate the sludge towards the center of the pipe. At the same time, the shearing force of the inclined side can more efficiently break up sludge clumps containing impurities.

[0048] 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.
