Description

Technical Field

[0001] This utility model relates to the field of tank sealing technology, and in particular to an electric heating end cap with good sealing performance. Background Technology

[0002] In industrial production, food processing, chemical reaction, and warehousing and transportation, tanks are core equipment for material storage, reaction, or transportation. Their end sealing and temperature control directly affect production efficiency, product quality, and operational safety.

[0003] However, traditional tank end cap designs focus only on mechanical sealing functions and lack heating capabilities. This results in the inability to continuously provide heat when handling easily solidified media (such as oils, resins, and liquid sulfur), materials requiring constant temperature reactions (such as fermentation broth and polymer synthesis raw materials), or low-temperature refrigerated materials (such as dairy products and biological agents). This can easily lead to undesirable changes in the stored materials and affect subsequent production. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing an electric heating end cap with good sealing performance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a well-sealed electric heating end cap, comprising a connecting mechanism, a flip-top mechanism, and a heating mechanism. The connecting mechanism is fixedly connected to the can opening, the flip-top mechanism is disposed on the upper side of the connecting mechanism, and the heating mechanism is installed on the lower side of the flip-top mechanism and located in the middle of the connecting mechanism. The heating mechanism is located at the can opening. The heating mechanism includes a mounting shell, electrical components, connecting terminals, a resistance ring, and an inner shell. The electrical components are fixedly connected inside the mounting shell and connected to the connecting terminals via wires. The connecting terminals are fixedly connected to both ends of the connecting terminals. The resistance ring is adhered to the inner side of the inner shell, and the inner shell is threadedly connected to the lower end of the mounting shell.

[0006] Preferably, the connecting mechanism includes a connecting disc and a convex ring, wherein the convex ring is fixedly connected to the upper middle part of the connecting disc.

[0007] Preferably, the flip-top mechanism includes a cover locking assembly, a cover body, and a cover sealing assembly. The cover locking assembly is disposed above the cover body, the cover sealing assembly is disposed below the cover body, and the mounting shell is fixedly connected to the lower side of the cover body.

[0008] Preferably, the cover sealing assembly includes a spring and a rubber ring, and an annular groove is provided on the lower side of the cover body. Multiple sets of springs are fixedly connected inside the annular groove, and the rubber ring is fixedly connected to the lower end of the multiple sets of springs.

[0009] Preferably, the rubber ring has a groove on its lower side to accommodate the protruding ring, and the mounting shell is located inside the rubber ring.

[0010] Preferably, the cover locking assembly includes a pressure rod, a handle, a threaded rod, and a sleeve rod. One end of the pressure rod is rotatably connected to one end of the connecting plate, the cover body is rotatably connected to the middle of the pressure rod, and the other end of the pressure rod abuts against the lower side of the handle.

[0011] Preferably, the threaded rod is fixedly connected to the upper end of the sleeve rod, the sleeve rod is rotatably connected to the other end of the connecting plate, the handle is threadedly connected to the upper end of the threaded rod, and the threaded rod is engaged in the notch at the other end of the pressure rod.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, external power is applied to the resistance ring through electrical components and connecting terminals, causing it to generate heat. An aerogel felt is pasted inside the mounting shell. Its thermal conductivity is extremely low, and its excellent heat insulation performance can prevent heat from being conducted to the outside. Instead, it is conducted to the inner shell made of stainless steel, thereby spreading to the can opening and heating the inside of the can, controlling the temperature within a suitable range, and thus maintaining the stability of the material state.

[0014] 2. In this utility model, when sealed storage is required, the threaded rod is locked in the notch at the end of the pressure rod, and the ring groove below the rubber ring locks the convex ring. By continuously rotating the handle, the handle presses down on the end of the pressure rod, and the pressure rod presses down on the cover, thereby squeezing multiple sets of springs to deform and generate elastic force. Under the action of elastic force, the rubber ring tightly fits the convex ring, improving the sealing effect. Attached Figure Description

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a well-sealed electric heating end cap, including a connecting mechanism 1, a flip-top mechanism 2, and a heating mechanism 3. The connecting mechanism 1 is fixedly connected to the can opening, the flip-top mechanism 2 is disposed on the upper side of the connecting mechanism 1, and the heating mechanism 3 is installed on the lower side of the flip-top mechanism 2 and located in the middle of the connecting mechanism 1. The heating mechanism 3 is located at the can opening. The heating mechanism 3 includes a mounting shell 31, an electrical component 32, a connecting terminal 33, a resistance ring 34, and an inner shell 35. The electrical component 32 is fixedly connected inside the mounting shell 31 and is connected to the connecting terminal 33 through a wire. The connecting terminal 33 is fixedly connected to both ends of the connecting terminal 33. The resistance ring 34 is bonded to the inner side of the inner shell 35, and the inner shell 35 is threadedly connected to the lower end of the mounting shell 31. The connecting mechanism 1 includes a connecting plate 11 and a convex ring 12, and the convex ring 12 is fixedly connected to the upper middle part of the connecting plate 11.

[0023] The specific setup and function of this embodiment are described below: Electrical component 32 is connected via a power cord, and electrical component 32 is connected to two sets of connection terminals 33 via wires. External power is applied to the resistance ring 34 through electrical component 32 and connection terminals 33, causing it to generate heat. Aerogel felt is pasted inside the mounting shell 31. Its thermal conductivity is extremely low, and its excellent heat insulation performance can prevent heat from being conducted to the outside. Instead, it is conducted to the inner shell 35 made of stainless steel, thereby spreading to the can opening and heating the inside of the can, controlling the temperature within a suitable range, and thus maintaining the stability of the material state.

[0024] Example 2: Figure 1 - Figure 3As shown, the flip-top mechanism 2 includes a cover locking assembly, a cover body 25, and a cover sealing assembly. The cover locking assembly is located above the cover body 25, and the cover sealing assembly is located below the cover body 25. The mounting shell 31 is fixedly connected to the lower side of the cover body 25. The cover sealing assembly includes a spring 27 and a rubber ring 28. An annular groove 26 is formed on the lower side of the cover body 25. Multiple sets of springs 27 are fixedly connected inside the annular groove 26, and the rubber ring 28 is fixedly connected to the lower end of the multiple sets of springs 27. A groove for accommodating a protruding ring 12 is formed on the lower side of the rubber ring 28. The housing 31 is located inside the rubber ring 28. The cover locking assembly includes a pressure rod 21, a handle 22, a threaded rod 23, and a sleeve rod 24. One end of the pressure rod 21 is rotatably connected to one end of the connecting plate 11. The cover 25 is rotatably connected to the middle of the pressure rod 21. The other end of the pressure rod 21 abuts against the lower side of the handle 22. The threaded rod 23 is fixedly connected to the upper end of the sleeve rod 24. The sleeve rod 24 is rotatably connected to the other end of the connecting plate 11. The handle 22 is threadedly connected to the upper end of the threaded rod 23. The threaded rod 23 is locked in the notch at the other end of the pressure rod 21.

[0025] The overall effect of this embodiment is as follows: by passing multiple sets of bolts through the edge holes of the connecting plate 11, the connecting plate 11 and the sealing gasket are installed at the can opening. When it is necessary to store materials, the handle 22 is loosened and pushed outward, so that the handle 22 gradually disengages from the pressure rod 21. The threaded rod 23 is pulled out from the end notch of the pressure rod 21, releasing the lock on the cover 25. Pressing the end of the pressure rod 21 to lift it up allows the cover 25 to be separated from the convex ring 12. Materials are injected into the can through the convex ring 12. When it is necessary to seal the storage, the threaded rod 23 is locked in the end notch of the pressure rod 21, and the annular groove below the rubber ring 28 locks the convex ring 12. By continuously rotating the handle 22, the handle 22 presses down on the end of the pressure rod 21, and the pressure rod 21 presses down on the cover 25, thereby compressing multiple sets of springs 27 to deform and generate elastic force. Under the action of elastic force, the rubber ring 28 tightly fits the convex ring 12, improving the sealing effect.

[0026] The usage and working principle of this device are as follows: By installing the connecting plate 11 and the sealing gasket at the tank opening, when it is necessary to store materials, loosen and pull the handle 22 outward to pull the threaded rod 23 out from the notch at the end of the pressure rod 21, releasing the lock on the cover 25. Pressing the end of the pressure rod 21 will lift it up, separating the cover 25 from the convex ring 12. Materials can be injected into the tank through the convex ring 12. When it is necessary to seal the storage, the threaded rod 23 is locked in the notch at the end of the pressure rod 21, and the annular groove below the rubber ring 28 locks the convex ring 12. Continuously rotating the handle 22 will press down the end of the pressure rod 21, pressing... The rod 21 presses down on the cover 25, thereby compressing multiple sets of springs 27 to deform and generate elastic force. Under the action of elastic force, the rubber ring 28 tightly fits the convex ring 12, improving the sealing effect. At the same time, the power cord passes through the cover 25 to connect to the electrical component 32. The electrical component 32 is connected to two sets of connection terminals 33 through wires. External power acts on the resistance ring 34 through the electrical component 32 and the connection terminals 33, causing it to generate heat. The heat is conducted to the inner shell 35 made of stainless steel, thereby spreading to the can opening and heating the inside of the can, controlling the temperature within a suitable range, and thus maintaining the stability of the material state.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
