[0025] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.
[0026] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They 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. Therefore, they should not be construed as limitations on this utility model.
[0027] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.
[0028] An embodiment of this utility model provides a steam heating device, such as... Figure 1-3 As shown, the device includes a heating chamber 100, a steam pipe 200, a support 300, and a feed hopper 400. The heating chamber 100 is filled with water, and the water level is pre-set by those skilled in the art according to the needs of the feed hopper 400. The heating chamber 100 has an opening at the top, through which the feed hopper 400 is placed into or removed from the heating chamber 100. The top of the heating chamber 100 is provided with an openable and closable cover 110. When the cover 110 is opened, the opening is exposed; when the cover 110 is closed, it provides a certain degree of sealing, reducing heat loss.
[0029] A support bracket 300 is fixed to the inner bottom wall of the heating chamber 100, and the support bracket 300 includes a top plate 310 located on top of it. A material tank 400 is used to hold the additive to be heated, and the material tank 400 is placed on the top plate 310. The top plate 310 can stably support the material tank 400, and at the same time, a space is reserved below the top plate 310 for the installation of a steam pipe 200. The steam pipe 200 extends from the outside of the heating chamber 100 into the heating chamber 100, and the steam pipe 200 includes a steam outlet pipe 210 located below the top plate 310. The surface of the steam outlet pipe 210 is provided with multiple vent holes 211, and the steam pipe 200 can be connected to a steam generator.
[0030] When using the steam heating device of this embodiment, place the drum 400 loaded with the auxiliary agent to be heated on the top plate 310, close the cover 110, and then transport steam through the steam pipe 200. The steam enters the water through the air outlet 211, and then heats the water in the heating box 100. Then, the hot water transfers heat to the auxiliary agent in the drum 400 to preheat the auxiliary agent. In this way, safety accidents are basically not likely to occur, and the safety is higher.
[0031] At the same time, the drum 400 and the steam outlet pipe 210 form a layout similar to a stacked structure through the bracket 300. This layout can reduce the bottom area of the entire heating box 100 and reduce the occupation of the ground space.
[0032] It should be noted that when using the steam heating device of this embodiment, the steam introduced should have a certain pressure so that the steam can overcome the water pressure in the heating box 100 and smoothly discharge from the air outlet 211.
[0033] In some embodiments, the bracket 300 further includes two support plates 320. The two support plates 320 are respectively located at both ends in the length direction of the top plate 310. The bottoms of the two support plates 320 are both connected to the inner bottom wall of the heating box 100, and the tops of the two support plates 320 are respectively connected to both ends in the length direction of the top plate 310.
[0034] This structure makes the cross-section of the bracket 300 form a structure similar to a "U" shape. The top plate 310 is lifted by the support plates 320, and there is enough space between the two support plates 320 to install the steam outlet pipe 210. Among them, the bottoms of the two support plates 320 can be welded and fixed on the inner bottom wall of the heating box 100.
[0035] Furthermore, guide plates 330 are connected to both ends in the width direction of the top plate 310. The guide plates 330 are arranged obliquely upward, and in the direction in which the two guide plates 330 are away from each other, the height of the guide plates 330 gradually increases.
[0036] Since support plates 320 are provided at both ends in the length direction of the top plate 310, the support plates 320 will block the steam. The steam mainly escapes from both ends in the width direction of the top plate 310. Due to the presence of the guide plates 330, the bubbles will flow upward along the guide plates 330. On the one hand, this can extend the flow path of the bubbles, thereby improving the heat exchange efficiency. On the other hand, this structure makes the bubbles relatively far away from the drum 400, and the bubbles are not easily attached to the outer wall of the drum 400, avoiding the accumulation of bubbles.
[0037] The angle between the guide plate 330 and the horizontal direction can be determined by those skilled in the art according to the actual situation. For example, it can be 45 degrees.
[0038] Furthermore, the top of the guide plate 330 is also connected to an upwardly extending upper baffle 340, which can prevent the bubbles from approaching the material barrel 400 during their upward movement, making it less likely for the bubbles to adhere to the outer wall of the material barrel 400.
[0039] In this embodiment, the top plate 310 and the support plate 320 can be integrally formed, the guide plate 330 and the upper baffle 340 can be integrally formed, and the guide plate 330 can be welded and fixed to the top plate 310.
[0040] In some embodiments, the steam outlet pipe 210 is arranged in a serpentine pattern, which makes the distribution of the vent holes 211 relatively uniform and improves the heating effect on the water. Both support plates 320 are provided with through holes 321 for the steam outlet pipe 210 to pass through. The support plates 320 can support both sides of the entire steam outlet pipe 210 and position the steam outlet pipe 210.
[0041] Furthermore, a bracket 220 is fixed to the bottom of the steam outlet pipe 210. The bracket 220 is connected to the inner bottom wall of the heating box 100, providing support for the middle part of the steam outlet pipe 210 and reducing deformation of the steam outlet pipe 210. A clamp is fitted on the outside of the steam outlet pipe 210, which is connected to the top of the bracket 220. The bottom of the bracket 220 is welded and fixed to the inner bottom wall of the heating box 100.
[0042] In some embodiments, a support rod 350 is also fixed to the bottom of the top plate 310, and the support rod 350 is connected to the inner bottom wall of the heating box 100. The support rod 350 provides support for the top plate 310, reducing the deformation of the top plate 310, and the bottom of the support rod 350 can be welded and fixed to the inner bottom wall of the heating box 100.
[0043] In some embodiments, the top surface of the top plate 310 is provided with an upwardly protruding limiting ring 360, and the bottom of the material bucket 400 is placed inside the limiting ring 360. The limiting ring 360 can restrict the material bucket 400 from sliding laterally on the top plate 310, so that the material bucket 400 remains stable.
[0044] In some embodiments, the steam pipe 200 is connected to a steam control valve 230. By operating the steam control valve 230, the steam pipe 200 can be opened or closed, and the steam flow rate can be adjusted to control the water temperature.
[0045] In some embodiments, a water supply pipe 120 and an overflow pipe 130 are connected to the side wall at the top of the heating box 100, and a drain pipe 140 is connected to the side wall at the bottom of the heating box 100. The water supply pipe 120 is connected to a water supply switch valve 121, and the drain pipe 140 is connected to a drain switch valve 141.
[0046] Water can be added to the heating tank 100 through the water supply pipe 120. When the water level in the heating tank 100 exceeds the overflow pipe 130, the overflow pipe 130 can discharge the excess water, and the drain pipe 140 can be used to empty the water in the heating tank 100.
[0047] The terms and words used in the foregoing description and claims are not limited to their literal meaning, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, those skilled in the art should understand that the foregoing description of various embodiments of the present invention is for illustrative purposes only, and not intended to limit the present invention as defined by the appended claims and their equivalents.
