Description

Technical Field

[0001] This utility model relates to the field of evaporator technology, and in particular to a foam removal device for evaporator steam pipes. Background Technology

[0002] An evaporator is a heat exchange device, along with a compressor, condenser, and expansion valve, collectively known as the four major components of refrigeration equipment. Its working principle is that when the refrigerant liquid vaporizes within it, it absorbs heat from the object being cooled, thus achieving the purpose of refrigeration. An evaporator mainly consists of a liquid evaporation zone, a steam inlet, a heating surface, and a secondary steam outlet. Based on the properties of the object being cooled, it can be classified into three types: liquid evaporators, air evaporators, and contact evaporators. According to whether the material circulates, it can be further divided into single-pass evaporators and circulating evaporators. Evaporators have wide applications in industries such as chemical, food, and pharmaceuticals, where they can be used to concentrate dilute solutions to produce products, recover solvents, or obtain pure solvents. In refrigeration equipment such as air conditioners and refrigerators, the evaporator is an important component for outputting cooling capacity, lowering indoor or refrigerator temperatures to create a comfortable environment or preserve food. In addition, there are high-efficiency and energy-saving evaporators such as MVR evaporators, which recover and utilize the latent heat of secondary steam, demonstrating significant advantages in areas such as wastewater evaporation treatment, and featuring energy saving, environmental protection, and ease of operation.

[0003] In the evaporation and concentration process, some materials often have high viscosity. This is due to the inherent properties of the material or changes in composition during concentration. When such materials reach their boiling point, due to their high viscosity, the gas has difficulty diffusing smoothly in the liquid and is not easy to escape, thus generating a large number of bubbles. These bubbles approach and overlap due to the high liquid resistance. As evaporation continues, the bubbles accumulate energy and rise. Eventually, they overcome various resistances and leave from the evaporator pipes. If this phenomenon is not controlled, it may cause problems such as material spraying, affecting production efficiency and product quality. To address this technical problem, this application proposes a defoaming device for evaporator steam pipes. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a foam removal device for evaporator steam pipes. The device uses a stepper motor to drive the connecting pipe to rotate in both directions. When rotating in the forward direction, the winding reel rotates to wind up the first pull rope, which in turn pulls the rotating rod to rotate the cleaning plate. When rotating in the reverse direction, the winding reel reverses, causing the torsion spring to drive the cleaning plate to rotate in the reverse direction to remove foam.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A foam removal device for evaporator steam pipes includes a pipe, an outer shell fixedly connected to the outer wall of the pipe, a limiting groove formed on the front side of the outer shell, a filter screen inserted into the inner wall of the limiting groove, a rotating rod connected to the inner wall of the filter screen via a torsion spring, a cleaning plate fixedly connected to the right side of the rotating rod, a winding reel rotatably connected to the inner wall of the filter screen, a first pull rope fixedly connected to the outer wall of the winding reel, the rear end of the first pull rope being fixedly connected to the outer wall of the rotating rod, two fixing grooves formed on the right side of the limiting groove, limiting blocks slidably connected to the inner wall of the fixing grooves, the left side of the limiting blocks being inserted into the right side of the filter screen, and the right sides of the two limiting blocks being connected via a limiting assembly for adjusting the sliding of the limiting blocks.

[0007] Furthermore, the limiting component includes a second pull rope fixedly connected to the right side of the limiting plug, and a limiting handle is fixedly connected to the front ends of the two second pull ropes.

[0008] Furthermore, a second spring is fixedly connected to the inner wall of the fixing groove, and the left end of the second spring is fixedly connected to the right side of the limiting block.

[0009] Furthermore, a pulley is rotatably connected to the right side of the inner wall of the fixing groove, and the outer wall of the pulley abuts against the outer wall of the second pull rope.

[0010] Furthermore, a stepper motor is fixedly connected to the front side of the housing, a connecting tube is fixedly connected to the drive end of the stepper motor, a rotating tube is slidably connected to the inner wall of the connecting tube, and the right side of the outer wall of the rotating tube is inserted into the inner wall of the winding reel.

[0011] Furthermore, a first spring is fixedly connected to the left side of the inner wall of the connecting tube, and the right end of the first spring is fixedly connected to the left end of the rotating tube.

[0012] Furthermore, the inner wall of the filter screen is rotatably connected with multiple balls, and the top of the balls abuts against the bottom side of the outer wall of the first pull rope.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the connecting tube is driven to rotate forward and backward by starting a stepper motor. When rotating forward, the take-up reel rotates to take up the first pull rope, and the first pull rope pulls the rotating rod to rotate, causing the cleaning plate to rotate. When rotating backward, the take-up reel rotates in reverse, thereby causing the torsion spring to drive the cleaning plate to rotate in reverse to remove foam.

[0015] 2. In this utility model, by pulling the limit handle, the second pull rope pulls the limit block to slide, releasing the fixation of the filter screen. Pressing the rotating tube causes the rotating tube to retract into the connecting tube, releasing the limit on the winding reel, and cleaning the filter screen. Attached Figure Description

The stepper motor 3 rotates in both directions using existing technology. A connecting tube 5 is fixedly connected to the drive end of the stepper motor 3. A rotating tube 6 is slidably connected to the inner wall of the connecting tube 5. The stepper motor 3 drives the connecting tube 5 to rotate in both directions, and the rotation of the connecting tube 5 causes the rotating tube 6 to rotate. The right side of the outer wall of the rotating tube 6 is inserted into the inner wall of the winding reel 9. The rotation of the rotating tube 6 causes the winding reel 9 to rotate, and the winding reel 9 rotates to wind up the first pull rope 13. A first spring 8 is fixedly connected to the left side of the inner wall of the connecting tube 5. The right end of the first spring 8 is fixedly connected to the left end of the rotating tube 6. The first spring 8 releases its elastic force to push the rotating tube 6 to slide. Multiple ball bearings 14 are rotatably connected to the inner wall of the filter screen 4. The top of the ball bearings 14 abuts against the bottom side of the outer wall of the first pull rope 13, making the movement of the first pull rope 13 smoother.

[0025] Reference Figure 1 , Figure 4 and Figure 5 Two fixing grooves are provided on the right side of the limiting groove, and the inner wall of the fixing groove is slidably connected to the limiting block 10, as shown in the figure. Figure 2 The left side of the limiting block 10 is inserted into the right side of the filter screen 4, limiting the movement of the filter screen 4.
