[0002] In industrial production, the ring cooler is an important equipment and is widely used in various process flows. In order to ensure the normal operation and efficiency of the ring cooler, the water seal structure is generally adopted as the sealing form of the ring cooler. The water seal is widely accepted because of its simple and effective sealing effect. However, with the long-term operation of the ring cooler, dust will gradually accumulate in the water seal tank, forming material accumulation and siltation.

[0003] These accumulated materials and silt will not only create resistance to the operation of the annular cooler and reduce its working efficiency, but also may cause equipment failure over time, increasing the cost of maintenance and replacement. In order to solve this problem, the commonly used method is to manually clean the accumulated materials and silt in the water tank. However, this method has obvious limitations, such as large cleaning workload, long time, and difficult to ensure the cleaning effect. What's more serious is that manual cleaning during the operation of the annular cooler has serious safety hazards, which may cause injury to operators and damage to equipment.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail in combination with the embodiments below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0019] See also Figure 1 and Figure 2 A dredging device in a sealed water tank of a ring cooler comprises a sealed water tank 1, a suspension beam 2 is installed above the sealed water tank, a suspension frame 3 is fixedly installed below the suspension beam, an electric screw reclaimer 4 is hingedly installed on the suspension frame through a first pin shaft, a material receiving funnel 5 is provided at the discharge port position at the upper end of the electric screw reclaimer, the lower end of the material receiving funnel is connected to a conveying pipe 6, and the lower end of the conveying pipe extends to a sludge collection box 7.

[0020] The structural advantages of the above technical solution are described below:

[0021] Sealed water tank and suspension structure:

[0022] Advantages: Through the design of suspension beam and suspension frame, the electric screw reclaimer can be flexibly suspended above the sealed water tank, which is convenient for installation, commissioning and maintenance. This structure not only ensures the stability of the reclaimer, but also enables the silt removal device to adapt to sealed water tanks of different sizes and shapes.

[0023] The matching structure of electric screw reclaimer and receiving hopper:

[0024] Advantages: The electric screw reclaimer uses the spiral rotation to remove the accumulated materials and silt in the water tank and collects them centrally through the receiving funnel. This method is both efficient and labor-saving, greatly improving the dredging efficiency. The design of the receiving funnel ensures that the accumulated materials can flow smoothly into the conveying pipe to avoid blockage and scattering.

[0025] The matching structure of the conveying pipe and the sludge collection box:

[0026] Advantages: The accumulated materials and silt are transported to the sludge collection box through the conveying pipe, realizing the centralized treatment of the accumulated materials. This design not only simplifies the dredging process, but also makes the treated sludge easier to handle and utilize in the future.

[0027] Further preferably, the outer side of the reducer housing of the electric screw reclaimer is symmetrically provided with a first pin shaft 3-1, and the center of gravity is particularly offset on the side close to the motor. This technical feature brings the following significant advantages:

[0028] Ensure continuous contact: Due to the offset center of gravity design, the electric screw reclaimer can use its own gravity when working to ensure that the screw reclaiming part always maintains contact with the silt at the bottom of the sealed water tank. This means that no matter how the depth of the silt in the water tank changes, or how the terrain at the bottom of the water tank undulates, the reclaimer can stably carry out the reclaiming operation without interruption or inefficiency caused by poor contact.

[0029] Improve dredging efficiency: Since the electric screw reclaimer is always in contact with the silt, it can continuously reclaim materials, reducing the time required to adjust the position of the reclaimer or re-contact the silt. This continuous operation capability greatly improves the overall efficiency of dredging, making the entire dredging process faster and more efficient.

[0030] Simplified operation and maintenance: Due to the clever design, operators do not need to frequently adjust the position and angle of the reclaimer, which simplifies the operation process. At the same time, this design also reduces the possible failure and wear of the reclaimer during the dredging process, reducing the frequency and cost of maintenance.

[0031] Strong adaptability: Whether facing sludge with high viscosity or loose accumulated materials, this gravity center offset design can ensure that the reclaimer works stably and efficiently. This design enables the dredging device to adapt to the dredging needs in different environments and conditions, improving the versatility and adaptability of the device.

[0032] In summary, the first pin shaft symmetrically arranged on the outer side of the reducer housing of the electric screw reclaimer and the center of gravity offset design close to the motor side not only ensure that the reclaimer always keeps in contact with the silt and improves the dredging efficiency, but also simplifies the operation and maintenance process and enhances the adaptability and stability of the device. This technical feature is an important innovation in the design of dredging devices, which has brought substantial improvements and benefits to the dredging work of the annular cooler sealed water tank.

[0033] Further preferably, a slewing seat 8 is fixedly mounted on the feeding barrel of the electric screw reclaimer, a lead screw 9 is movably mounted on the slewing seat, a shaft head 10 is provided at the lower end of the lead screw, the shaft head is inserted into the through hole of the slewing seat, and a limiting member 11 is provided on the shaft head inside the slewing seat; an electric screw reclaimer lifting beam 12 is provided above the sealed water tank, a lifting seat 13 is fixedly mounted on the lifting beam of the electric screw reclaimer on the lead screw side, a threaded sleeve 14 is hingedly mounted on the lifting seat through a second pin shaft 13-1, the lead screw is inserted into the threaded sleeve, and is threadedly matched with the threaded sleeve. Through the cooperation of the lead screw and the threaded sleeve, the electric screw reclaimer can realize lifting and lowering motion under the guidance of the lifting beam of the electric screw reclaimer, thereby adjusting the feeding depth. This design enables the dredging device to adapt to sealed water tanks of different depths, thereby improving the versatility and adaptability of the device.

[0034] Further preferably, the limiting member is a limiting ring, which is clamped in the limiting ring groove of the shaft head. The limiting member can also be a nut, which is screwed on the shaft head. The design of the limiting ring can ensure the stability of the position of the shaft head in the swivel seat and prevent the screw from axial movement during operation. When the nut is used as the limiting member, the position of the shaft head can be fixed by adjusting the tightness of the nut. This design is simple and practical, ensuring the stability and reliability of the dredging device.

[0035] Preferably, the bottom of the bolt reclaimer is provided with a guide slope. The design of the guide slope helps the accumulated materials and silt to be concentrated at one end in the sealed water tank, so as to facilitate the electric screw reclaimer to collect the materials in a centralized manner. This design improves the dredging efficiency and reduces the omission and scattering that may occur during the dredging process.

[0036] Further preferably, the delivery pipe adopts a flexible corrugated pipe. By adopting a flexible corrugated pipe as the delivery pipe, the direction and angle of the delivery pipe can be easily adjusted to adapt to different installation and use scenarios. At the same time, the flexible corrugated pipe has good wear resistance, corrosion resistance and aging resistance, which can ensure the long-term stable operation of the delivery pipe.

[0037] In summary, the desilting device in the sealed water tank of the annular cooler realizes the automated desilting process by virtue of the efficient desilting capability of its electric screw reclaimer. The structural design is flexible and stable, ensuring the reliability of long-term operation. At the same time, the device focuses on environmental protection and energy saving, reducing the impact on the environment. Simple maintenance operations and low-cost component replacement also bring economic benefits to the enterprise. Overall, the device provides comprehensive guarantees for the normal operation and maintenance of the annular cooler with its advantages of high efficiency, stability, environmental protection and economy.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
