Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and in particular relates to a pre-buried base for silt flushing and silting execution equipment. Background Art

[0002] In the water treatment sector, especially in systems such as negative pressure diversion chambers that require precise water level control and maintain a negative pressure environment, silt flushing and desilting equipment is a key component. Its performance and stability directly impact the overall system's operational efficiency and safety. This equipment generates a powerful vacuum effect, raising the water level. Once the vacuum is lost, the elevated water rapidly flushes under its own weight, effectively desilting the sump.

[0003] However, existing installation methods for flushing and silting actuators primarily rely on pre-buried flange connections. While this traditional method meets basic connection requirements to a certain extent, it presents numerous drawbacks in practical applications. First, due to the limited sealing performance between the flange and the pre-buried foundation, air leakage often occurs around the flushing and silting actuators after activation. This not only directly leads to the loss of negative pressure, compromising flushing effectiveness and water level control accuracy, but also increases the system's energy consumption and maintenance costs.

[0004] Secondly, traditional embedded seats often overlook strength in their structural design, making them unable to withstand the challenges of long-term operation and complex environments. Over time, the embedded seats may deform or damage due to material fatigue, corrosion, or external impact, affecting the stable operation of the flushing and silting equipment and the overall safety of the system.

[0005] Given these issues, the market urgently needs a new pre-buried base for flushing and silting equipment to address the air leakage and structural deficiencies of existing installation methods. This new base should have excellent sealing properties to ensure that the flushing and silting equipment can maintain a stable negative pressure environment after startup. At the same time, it should also have sufficient structural strength to cope with the various challenges brought by long-term operation and complex environments, ensuring the long-term stable operation of the system. Utility Model Content

[0006] In view of the problems existing in the prior art, the utility model provides a pre-buried base for silt flushing and silting execution equipment.

[0007] The present utility model is implemented as follows: a pre-buried base for silt flushing and silt execution equipment comprises a cylinder with a circular structure, and is characterized in that an upper connecting flange is welded at the upper end of the cylinder for connecting the silt flushing and silt execution equipment, a waterproof wing ring is welded at the outer wall of the lower end of the cylinder for preventing water vapor from communicating upward and downward at the fitting surface between the pre-buried foundation and the outer wall of the cylinder, and a vertical air stop plate is welded at the lower end face of the waterproof wing ring along the circumferential direction.

[0008] Preferably, two vertical air-stop plates are provided along the circumferential direction, and the two vertical air-stop plates are arranged in radial symmetry.

[0009] Preferably, a connecting hole is provided on the side wall of the cylinder in a direction perpendicular to the two air-stop plates. The connecting hole does not pass through the cylinder and is used to connect a connecting pipe.

[0010] Preferably, the center of the communicating hole and the center of the waterproof wing ring are located on the same plane.

[0011] Preferably, a lower suspension flange is welded to the inner wall of the lower end of the cylinder for mounting a detection and control element support plate.

[0012] Preferably, the waterproof wing ring is located in the lower middle part of the cylinder.

[0013] The advantages and technical effects of the present invention are as follows: the embedded base of the silt flushing and silt removal equipment adopts a circular structural design. This unique configuration gives it good symmetry and uniformity, allowing the base to withstand uniform pressure from all directions, thereby significantly improving the overall structural strength and stability. The upper end of the base is cleverly welded with an upper connecting flange. This design not only facilitates the connection between the silt flushing and silt removal equipment and the base, but also ensures the stability and sealing of the connection between the two. As a mature and reliable connection method, flange connection enables the silt flushing and silt removal equipment to remain stable during operation without fear of external interference.

[0014] To further enhance the base's waterproof and leak-proof properties, the designers welded a waterproof wing ring to the outer wall of the lower end of the cylinder. This ingenious design effectively prevents moisture from flowing upwards and downwards between the embedded foundation and the outer wall of the cylinder, preventing moisture from penetrating the base. This protects the base and the silt flushing and desilting equipment from water erosion, extending their service life. Furthermore, a vertical air-stop plate is welded circumferentially to the lower end of the waterproof wing ring. This design further enhances the base's sealing performance, effectively preventing leaks and ensuring that the silt flushing and desilting equipment maintains a stable negative pressure environment after activation, improving the overall performance of the system.

[0015] In addition, this technology connects two independent flushing chambers through the connecting holes and connecting pipes on the base, enabling the desilting execution equipment to complete secondary flushing at the same time, significantly improving work efficiency, optimizing resource utilization, enhancing flushing effects, and improving the flexibility and maintainability of the equipment. It also helps promote technological innovation in related fields. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] Example 1, please refer to Figures 1 to 6, a pre-buried base for silt flushing and silt removal equipment, the pre-buried base is cast on the top plate of the vacuum negative pressure water diversion chamber, and is used to install the silt flushing and silt removal equipment 6, including a cylinder 1 with a circular structure. The circular structure has good symmetry and uniformity, can withstand uniform pressure from all directions, and improves the overall structural strength of the base. At the same time, the circular design is also convenient for processing and installation, reducing manufacturing costs and construction difficulty. An upper connecting flange 2 is welded to the upper end of the cylinder. The design of the upper connecting flange enables the silt flushing and silt removal equipment to be easily connected to the base, ensuring the stability and sealing of the connection. Flange connection is a mature connection method that can withstand large tension and pressure, ensuring the stability of the silt flushing and silt removal equipment during operation. The outer wall of the lower end of the cylinder is welded with a waterproof wing ring 3. The design of the waterproof wing ring effectively prevents water vapor from flowing up and down at the joint surface between the embedded foundation and the outer wall of the cylinder, prevents moisture from penetrating into the interior of the base, protects the base and the silt flushing and silt flushing execution equipment from moisture erosion, extends the service life, and improves the sealing effect. The lower end surface of the waterproof wing ring is welded with a vertical air stop plate 4 along the circumferential direction; the design of the vertical air stop plate further enhances the sealing performance of the base and effectively prevents the occurrence of air leakage. The air stop plate can prevent gas from leaking along the gap between the outer wall of the cylinder and the embedded foundation, ensuring that the silt flushing and silt flushing execution equipment can maintain a stable negative pressure environment after startup, thereby improving the overall performance of the system.

[0028] Preferably, two vertical air-stop plates are provided along the circumference, arranged radially symmetrically. This symmetrical design ensures a balanced blocking effect when preventing gas leakage, effectively blocking gas from any direction. Furthermore, the presence of the two air-stop plates increases the contact area between the base and the embedded foundation, improving overall stability and sealing. This more effectively maintains the negative pressure environment after the silt flushing and desilting equipment is activated, enhancing the overall performance and stability of the system.

[0029] Preferably, a lower suspension flange 5 is welded to the inner wall of the lower end of the cylinder for mounting a support plate for the detection and control element. The support plate is sealed to the lower suspension flange 5 to ensure sealing with the flushing chamber. A control valve for breaking the vacuum state of the flushing chamber and a liquid level detector are mounted on the support plate, thereby achieving efficient flushing of the flushing chamber using the flushing water sucked up by vacuum.

[0030] Preferably, the waterproof wing ring is located in the lower middle portion of the cylinder. Placing the waterproof wing ring in the lower middle portion of the cylinder makes the overall structural layout of the base more rational. This layout not only ensures waterproof performance, but also takes into account the coordination and cooperation with other components (such as the upper connecting flange and vertical air stop plate), making the base more functional.

[0031] Example 2, please refer to Figures 7 to 11A connecting hole is provided on the side wall of the cylinder in a direction perpendicular to the two air-stop plates. The connecting hole does not pass through the cylinder and is used to connect a connecting pipe.

[0032] This technology connects two independent flushing chambers through the connecting holes and connecting pipes on the base, enabling the silt flushing and desilting execution equipment to complete secondary flushing at the same time, significantly improving work efficiency, optimizing resource utilization, enhancing flushing effects, and improving the flexibility and maintainability of the equipment. It also helps promote technological innovation in related fields.

[0033] Preferably, the center of the connecting hole and the center of the waterproof wing ring are located on the same plane, and the alignment of the connecting hole and the center of the waterproof wing ring makes the entire structure present a symmetrical layout in the vertical direction, which helps to enhance the overall stability of the structure and reduce stress concentration caused by asymmetry.

[0034] In summary, the embedded base of the utility model adopts a circular structural design, which gives good symmetry and uniformity, and significantly improves the overall structural strength and stability. Secondly, the upper connecting flange welded on the upper end of the base ensures the stability and sealing of the connection between the equipment and the base, so that the equipment remains stable during operation. Furthermore, the design of the waterproof wing ring and the vertical air stop plate effectively prevents moisture penetration and air leakage, thereby extending the service life. In addition, this technology can realize the construction of a pump station that can complete secondary flushing at the same time, significantly improving work efficiency and resource utilization, enhancing the flushing effect, and improving the flexibility and maintainability of the equipment.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
