Description

Technical Field

[0002] A steam-heated hot plate is a heating device that uses steam as a heat source. It is usually made of metal sheet and has steam channels or cavities inside. When in operation, high-temperature steam enters the interior of the hot plate through pipes, transferring heat to the metal plate surface and raising the plate surface to the set temperature. This allows for the heating, drying, or heat preservation of materials placed on the plate. Steam-heated hot plates have advantages such as uniform heating, fast heating speed, and low cost, and are widely used in food processing, industrial production, and other fields.

[0003] Some steam heating plates have internal threads at the inlet and outlet of the steam channels to connect with the steam conveying pipes. In practical applications, there are cases where the assembly ring of the steam conveying pipe is too long or too short. When these situations occur, there are problems of mismatch and reduced sealing strength. Therefore, it is necessary to improve the internal steam channel structure of the steam heating plate to solve these problems. Utility Model Content

[0039] 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.

[0040] This utility model provides, for example Figure 1-4The steam channel structure inside the steam heating plate shown includes the hot plate body 1, the double circulation channel 2, and two assembly mechanisms 3. The double circulation channel 2 is opened inside the hot plate body 1. The design of the double circulation channel 2 completes the mutual compensation of the high and low steam temperatures at both ends of the steam heating plate, avoiding the phenomenon of high temperature at the steam inlet end and low temperature at the steam return end, thus improving accuracy. The two assembly mechanisms 3 are set at both ends of the double circulation channel 2. The assembly mechanisms 3 are used to improve the applicability of the connection between the steam heating plate and the steam pipeline. The two assembly mechanisms 3 have the same structure.

[0041] The assembly mechanism 3 includes a circular groove 31, an assembly hole 32, a wide-diameter hole 33, a narrow-diameter hole 34, an outer sealing component, and an inner sealing component. The circular groove 31 is located on the front side of the hot plate body 1. The assembly hole 32 is located on one side of the inner wall of the circular groove 31. The inner wall of the assembly hole 32 has evenly distributed internal threads. The assembly hole 32 is used to connect with the assembly ring of the steam pipe to complete the assembly work. The wide-diameter hole 33 is located inside the hot plate body 1. The diameter of the wide-diameter hole 33 is larger than that of the assembly hole 32, and the length of the wide-diameter hole 33 is larger than that of the assembly ring. The specific dimensions can be changed according to actual needs. The wide-diameter hole 33 is connected to the assembly hole 32. The narrow-diameter hole 34 is located between the wide-diameter hole 33 and the double circulation channel 2. The narrow-diameter hole 34 changes the diameter of the hole. The outer sealing component is located on the front side of the assembly hole 32. The outer sealing component is used to improve the sealing strength of the connection between the steam heating hot plate and the steam pipe. The inner sealing component is located on the back side of the assembly hole 32. The inner sealing component is used to improve the sealing strength of the connection between the steam heating hot plate and the steam pipe.

[0042] The outer sealing assembly includes an outer sealing ring 35, multiple slots, and multiple locking blocks 36. The outer sealing ring 35 is disposed in the inner cavity of the circular groove 31. The multiple slots are arranged in a ring array on the inner wall of the circular groove 31. The multiple locking blocks 36 are movably sleeved in the inner cavity of the corresponding slots. The multiple locking blocks 36 are all fixedly connected to the outer wall of the outer sealing ring 35. The locking blocks 36 and the outer sealing ring 35 are made of the same material. The locking blocks 36 and the slots are used to improve the stability of the outer sealing ring 35.

[0043] The inner sealing assembly includes a limiting sleeve 37, two connecting blocks 313, a limiting slide rod 38, an anti-detachment ball 314, a mounting ring 39, a crossbar 310, an inner sealing ring 311, and a compression spring 312. The limiting sleeve 37 is located inside the wide-diameter hole 33. The two connecting blocks 313 are symmetrically fixedly connected to the outer wall of the limiting sleeve 37, and both connecting blocks 313 are fixedly connected to the inner wall of the wide-diameter hole 33. The limiting slide rod 38 is slidably sleeved inside the limiting sleeve 37. The limiting sleeve 37 and the limiting slide rod 38 are used to limit the movement trajectory of the inner sealing ring 311 and improve the smoothness of the movement of the inner sealing ring 311. The anti-detachment ball 314 is fixedly connected to the top of the limiting slide rod 38 and is used to prevent the limiting slide rod 38 from detaching from the limiting sleeve. 37. The outer diameter of the anti-detachment ball 314 is larger than the inner diameter of the limiting sleeve 37. The mounting ring 39 is located below the limiting sleeve 37. The crossbar 310 is fixedly connected to the inner cavity of the mounting ring 39. The top of the crossbar 310 is fixedly connected to the bottom end of the limiting slide bar 38. The inner sealing ring 311 is fixedly connected to the bottom of the mounting ring 39. The inner diameter of the inner sealing ring 311 is larger than the inner diameter of the assembly ring but smaller than the outer diameter of the assembly ring. The compression spring 312 is sleeved on the outside of the limiting slide bar 38. The top of the compression spring 312 is fixedly connected to the bottom of the limiting sleeve 37. The bottom end of the compression spring 312 is fixedly connected to the top of the crossbar 310. The compression spring 312 can undergo elastic deformation, thereby driving the mounting ring 39 and the inner sealing ring 311 to automatically perform a reset movement.

[0044] Working principle of this utility model:

[0045] During the assembly of the steam heating plate and the steam pipe, the assembly ring of the steam pipe is inserted into the assembly hole 32 from the outer sealing ring 35. Then, the assembly ring is rotated clockwise. As the assembly ring rotates clockwise in the assembly hole 32, it gradually enters the wide-diameter hole 33, which exerts a compressive force on the inner sealing ring 311. As the assembly ring continues to enter the wide-diameter hole 33, the inner sealing ring 311 gradually moves towards the narrow-diameter hole 34 under the compression of the assembly ring. During this process, under the action of the compression spring 312, the inner sealing ring 311 will fit tightly against the end of the assembly ring. When the outer sealing ring 35 is compressed by the steam pipe and can no longer rotate the assembly ring, the assembly of the steam heating plate and the steam pipe is completed. This allows the steam channels of the steam heating plate to be connected to assembly rings of steam pipes of different lengths, ensuring sealing strength while improving applicability.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
