Description

Technical Field

[0001] The utility model relates to the technical field of evaporator defoaming, in particular to an evaporator defoaming device which is convenient to disassemble. Background Art

[0002] Evaporators are devices that convert liquid substances into gaseous substances. Evaporators are commonly used in the food, pharmaceutical, chemical and other industries. Evaporators are mainly composed of two parts: a heating chamber and an evaporation chamber. The heating chamber provides the liquid with the heat required for evaporation, causing the liquid to boil and vaporize, and the evaporation chamber completely separates the gas and liquid phases. The vapor generated in the heating chamber carries a large amount of liquid foam. After reaching the larger evaporation chamber, the liquid is separated from the vapor by its own condensation or the action of a defoamer.

[0003] In the prior art, there is an evaporator defoaming device disclosed in patent CN205516569U, in which multiple layers of defoaming screens are staggered on the inner wall of the evaporation chamber. When the steam in the evaporation chamber flows toward the outlet of the evaporation chamber and encounters the defoaming screens, the steam changes the airflow route through the multiple layers of defoaming screens, so that the crystals mixed in the steam are intercepted by the multiple layers of defoaming screens to achieve defoaming.

[0004] However, there are still some problems in the actual use of the above-mentioned defoaming equipment. For example, the defoamer will produce dirt after a period of use and needs to be disassembled and cleaned regularly. The existing defoaming equipment is not convenient for disassembling and replacing the defoamer, so it needs to be improved. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1 As shown, the evaporator defoaming device that is easy to disassemble in this embodiment includes a defoaming component 3 and a driving component 4. The shell 1 is provided with a corresponding heating component and an evaporating component. Both of them adopt the existing technology, and neither of them belongs to the content discussed in this application, so they are not described here. The end cover 2 is hinged on the top of the shell 1, the defoaming component 3 is arranged inside the shell 1 through the quick release component 5, the driving component 4 is arranged on the end cover 2 and is connected to the defoaming component 3, and the side wall at the bottom of the shell 1 is also provided with a support leg 6.

[0021] The driving assembly 4 includes a first motor 41, a second motor 42 and a connecting frame 43. The first motor 41 is arranged on the top of the end cover 2, the second motor 42 is arranged above the defoaming assembly 3 and is coaxially connected to the connecting shaft 34, and the first motor 41 and the second motor 42 are connected through the connecting frame 43.

[0022] like Figure 2 As shown, the defoaming assembly 3 includes a fixed ring 31, a rotating ring 32 and a plurality of defoaming screens 33. The rotating ring 32 is rotatably arranged on the inner side of the fixed ring 31. A connecting shaft 34 is provided at the center position of the rotating ring 32. The plurality of defoaming screens 33 are movably arranged on the rotating ring 32 along the circumferential direction. The outer wall of the connecting shaft 34 is connected to the defoaming screens 33 by a connecting rope 35. A return spring 36 is provided on the outer side of the connecting rope 35.

[0023] Among them, the foam removing screen 33 has a fan-shaped structure, and the two ends of the return spring 36 are respectively abutted against the outer wall of the connecting shaft 34 and the inner wall of the foam removing screen 33. A plurality of slideways 37 are radially spaced on the rotating circle 32, and the bottom of the foam removing screen 33 is slidably connected to the slideway 37.

[0024] The upper side of the connecting frame 43 is connected to the main shaft of the first motor 41, and the two sides are respectively connected to the upper end faces of the rotating circle 32. The first motor 41 drives the rotating circle 32 to rotate through the connecting frame 43, and the second motor 42 further drives the connecting shaft 34 to rotate. During the rotation of the connecting shaft 34, the connecting rope 35 is wound around its outer wall and the return spring 36 is compressed, so that the foam removing screen 33 moves toward the center of the rotating circle 32 along the slide 37. At the same time, because the first motor 41 drives the rotating circle 32 to rotate, the foam removing screen 33 performs a compound motion of linear + rotation.

[0025] When the second motor 42 rotates reversely, the return spring 36 stretches to pull the connecting rope 35 out of the connecting shaft 34, thereby realizing the reciprocating motion of the foam removal screen 33 through the forward and reverse rotation of the second motor 42, which can effectively remove the liquid foam in the evaporator.

[0026] like Figure 3 As shown, the quick-release assembly 5 includes a connecting rod 51, a pin 52, a rotating arm 53 and a block 54. The connecting rod 51 is arranged on both sides of the fixing ring 31, and the bottom of the rotating arm 53 is connected to the connecting rod 51 through the pin 52. The block 54 is arranged on the upper part of the rotating arm 53, and the inner wall of the shell 1 is provided with a slot 11 matching the block 54.

[0027] When the defoaming assembly 3 needs to be disassembled, the rotating arm 53 is pulled to disengage the block 54 from the groove 11. At this time, the defoaming assembly 3 can be disassembled from the shell 1, which is convenient for subsequent replacement and cleaning, and improves the maintenance efficiency of the defoaming assembly 3.
