Description

Technical Field

[0001] This utility model relates to the field of mechanical seal technology for agitators, specifically a mechanical seal device for agitators that can detect leaks. Background Technology

[0002] Agitators are widely used in chemical, pharmaceutical, and food industries to mix materials. During operation, the agitator shaft and base need to be sealed to prevent material leakage. Currently, the most common sealing method is mechanical seal, which mainly consists of a rotating ring, a stationary ring, and a spring. The seal is achieved through the tight fit between the rotating and stationary rings.

[0003] However, existing mechanical seal devices for agitators are prone to leakage during long-term use due to wear of the dynamic and static rings, spring failure, and other reasons. Leakage is often difficult to detect in a timely manner, which may lead to material loss, environmental pollution, and even safety accidents, equipment damage, and personal injury in some flammable, explosive, or toxic and harmful working conditions. Therefore, those skilled in the art provide a mechanical seal device for agitators that can detect leakage to solve the problems mentioned in the background art. Utility Model Content

[0020] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please see Figures 1-5 In this embodiment of the present invention, a leak-detecting mechanical seal device for an agitator includes a stationary ring assembly 1, an inner ring of which is connected to a rotating ring assembly 2, and an inner ring of the rotating ring assembly 2 is connected to a connecting shaft 3. A detection chamber 4 is formed inside the stationary ring assembly 1, and a leakage channel 5 is formed jointly inside the stationary ring assembly 1 and the rotating ring assembly 2. A pressure sensor 6 is installed on the inner wall of the detection chamber 4, and a wireless transmission module 7 is installed on the inner wall of the detection chamber 4. An intelligent controller 8 is installed on the outer surface of the stationary ring assembly 1. The interior of the stationary ring assembly 1 includes a stationary ring seat 101 and a stationary ring body 102, and the interior of the rotating ring assembly 2 includes a rotating ring seat 201 and a rotating ring body 202. The wireless transmission module 7 can remotely transmit leakage signals to a monitoring terminal for remote real-time monitoring. The intelligent controller 8 can analyze and process the data signals detected by the pressure sensor 6.

[0023] The outer surface of the static ring assembly 1 is connected to a support plate 9. The upper surface of the support plate 9 is connected to the bottom surface of the intelligent controller 8. An audible and visual alarm 10 is installed on the upper surface of the intelligent controller 8. A display screen 11 is installed on the front of the intelligent controller 8. The support plate 9 can support and reinforce the intelligent controller 8, making the connection between the intelligent controller 8 and the device more secure. The audible and visual alarm 10 can generate various alarm modes such as sound and light.

[0024] Sealing discs 12 are connected to the top and bottom of stationary ring assembly 1, as well as the top and bottom of rotating ring assembly 2. Two sets of annularly arranged reinforcing columns 13 are connected to the inner wall of stationary ring seat 101. The sides of the two sets of reinforcing columns 13 that are close to each other are connected to the outer surface of stationary ring body 102. The sealing discs 12 can further enhance the axial sealing performance, reduce the possibility of leakage on non-sealing surfaces, and improve the overall structural reliability and durability of the device. The reinforcing columns 13 provide uniform support for stationary ring assembly 1, reducing its deformation under long-term high-speed operation or pressure impact, and ensuring the fitting accuracy of the sealing surfaces of rotating ring assembly 2 and stationary ring assembly 1.

[0025] The working principle of this utility model is as follows: During normal operation, the moving ring assembly 2 rotates synchronously with the connecting shaft 3, while the stationary ring assembly 1 remains fixed. The contact surface between the moving ring body 202 and the stationary ring body 102 forms the main sealing surface, which prevents leakage of the stirring medium through tight fit. When leakage occurs due to wear, aging, or other reasons, the stirring medium will break through the main sealing surface and flow into the detection chamber 4 through the preset leakage channel 5. As the medium accumulates in the detection chamber 4, the pressure inside the chamber gradually increases. At this time, the pressure sensor 6 on the inner wall of the detection chamber 4 will capture the pressure change in real time and convert the signal into an electrical signal, which is transmitted to the intelligent controller 8. After analyzing and processing the signal, the intelligent controller 8 will promptly trigger the audible and visual alarm 10 to issue a warning, reminding on-site personnel to handle the situation in a timely manner. The above is the complete operation process of this product.
