Description

Technical Field

[0001] This application relates to evaporation equipment, and more particularly to a folding evaporation curtain and evaporation curtain assembly. Background Technology

[0002] Evaporation equipment is a device that concentrates salts by increasing the contact area between water and air. In related technologies, the evaporation curtains used in evaporation equipment have a planar structure. These curtains have a small evaporation area, and the liquid stays on them for a short time, resulting in low evaporation efficiency. Summary of the Invention

[0003] In view of this, this application provides a foldable evaporation curtain and evaporation curtain assembly, which can increase the evaporation area and the residence time of the liquid on the evaporation curtain.

[0004] To achieve the above objectives, this application employs the following technical solution:

[0005] A folding evaporation curtain, characterized in that: it includes a main body, the main body including a plurality of fixedly connected folding blades, each folding blade forming an alternating concave-convex corrugated shape in the vertical direction.

[0006] The aforementioned folded evaporation curtain of this application features a corrugated body, which increases the evaporation area and extends the residence time of the liquid on the curtain, thereby improving evaporation efficiency. Furthermore, the folded evaporation curtain, due to its folds, acts as a stacking guide when it descends and touches the bottom of the evaporation tank, making it less prone to wrinkling compared to a flat evaporation curtain.

[0007] In some embodiments, the main body has a porous structure, and the included angle α between two adjacent folded blades of the main body is 10°-15°. When the main body has a porous structure and the included angle between two adjacent folded blades is selected to be 10°-15°, due to the surface tension of water, the water adheres to the pores, so the liquid hardly flows, thereby increasing the residence time of the liquid on the evaporation curtain.

[0008] In some embodiments, the folding evaporator curtain also includes a straight section integrally connected to the main body. On the left and right sides of the straight section, there is a mounting component for fixing the evaporator curtain and facilitating its installation onto the bracket. When the two mounting components are installed onto the bracket, the straight section can be pulled flat from the left and right sides, and the tension can be adjusted using nuts on the mounting components. In this way, the straight section acts as a load-bearing beam, supporting the evaporator curtain and preventing it from bending downwards.

[0009] In some embodiments, the mounting assembly includes a first clamp and a second clamp disposed on the front and rear sides of the straight section. The first clamp has a plurality of pins, and the second clamp has a plurality of insertion holes for receiving the pins. The first and second clamps clamp the straight section from the front and rear sides. The pins pass through the holes in the straight section and extend into the insertion holes, thereby fixing the straight section. The first and second clamps are fixedly connected by a locking mechanism. One of the first and second clamps is provided with a connector for easy installation onto a bracket. The pins, when inserted into the evaporation curtain, can secure the evaporation mesh.

[0010] In some embodiments, the locking mechanism is a snap-fit ​​structure or a bolt structure. Preferably, there are two or more snap-fit ​​mechanisms.

[0011] In some embodiments, the connector is a screw fixedly connected to the first and second clamping plates, and the screw is secured to the bracket by a nut.

[0012] In some embodiments, one of the first and second clamping pieces is provided with a guide pin, and the other of the first and second clamping pieces is provided with a guide hole that mates with the guide pin. The engagement between the guide pin and the guide hole primarily serves to guide the installation process.

[0013] In some embodiments, the main body is provided with connecting ropes passing through each folding blade. These connecting ropes have several spaced-apart nodes or fasteners, thus forming a folding unit by assembling the same number of folding blades. The nodes are formed by knotting the connecting ropes, or by attaching fasteners, such as metal wires, to the connecting ropes. The function of these nodes or fasteners is to hold the corresponding folding blades in place. Preferably, ten folding blades are tied together at one node, thus forming multiple folding units. These folding units are relatively independent, preventing the evaporator curtain from bending downwards. The support between each unit relies on the ropes rather than the curtain itself, improving the lifespan of the evaporator curtain. The included angle between the upper and lower folding blades of the evaporator curtain can be maintained at 10-15°.

[0014] In some embodiments, the upper end of the connecting rope is fixedly connected to the mounting assembly. There are two connecting ropes, located on the left and right sides of the main body, respectively. As the two connecting ropes extend downwards, they gradually incline towards the center line of the main body. Since the center of gravity of the evaporator curtain is in the center, the folding blades are more likely to bend as they move downwards. Therefore, the lower part of the connecting rope is inclined towards the center line, which can further reduce the possibility of the evaporator curtain bending.

[0015] This application also provides an evaporation curtain assembly, characterized in that: it includes a bracket and a plurality of the above-mentioned folding evaporation curtains, the bracket including two side rods spaced apart on the left and right and a crossbar for fixing the two side rods together, the folding evaporation curtains being mounted on the two side rods by mounting components on their left and right sides, the two mounting components straightening the straight portion of the folding evaporation curtains.

[0016] The bracket uses a combination of two side bars and a crossbar, so that there is almost no obstruction above the evaporation curtain, resulting in high evaporation efficiency. Moreover, the straight section is straightened by two mounting components, which forms a beam-like structure that prevents the evaporation curtain from bending downwards.

[0017] In some embodiments, a heat-absorbing net is provided above each folded evaporation curtain, and multiple capillary tubes located between two adjacent folded evaporation curtains and extending into the evaporation pool are fixedly connected to the heat-absorbing net.

[0018] The capillary tubes have a capillary effect, which can guide the liquid in the evaporation tank below to the heat absorption net for auxiliary evaporation. They can also make the most of the space between the two folded evaporation curtains. The heat absorption net is coated with a heat absorption layer, which has a high temperature and can increase the upward airflow, further improving the evaporation effect.

[0019] As can be seen from the above technical solution, this application has at least the following advantages and positive effects:

[0020] This application discloses a folded evaporation curtain, in which the main body of the evaporation curtain is designed with a corrugated shape, which increases the evaporation area and prolongs the residence time of the liquid on the evaporation curtain, thereby improving evaporation efficiency. Furthermore, when the folded evaporation curtain descends and contacts the bottom of the evaporation tank, causing accumulation, the guiding effect of the folds makes it less prone to wrinkling compared to a flat evaporation curtain.

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the application will be described in further detail below with reference to the accompanying drawings. The terminology used in the embodiments section of this application is only for explaining specific embodiments and is not intended to limit the application.

[0031] Example 1

[0032] See Figures 1 to 5 This application provides a folding evaporation curtain 5, which includes a main body 1. The main body 1 includes a plurality of fixedly connected folding blades 11, and each folding blade 11 forms an alternating corrugated shape in the vertical direction.

[0033] The folded evaporation curtain 5 has a corrugated body 1, which increases the evaporation area and prolongs the residence time of the liquid on the evaporation curtain, thus improving evaporation efficiency. Furthermore, the folded evaporation curtain, due to its folds, acts as a stacking guide when it descends and touches the bottom of the evaporation tank, making it less prone to wrinkling compared to a flat evaporation curtain.

[0034] The main body 1 has a porous structure, and the included angle α between two adjacent folded blades 11 of the main body 1 is 10°-15°. When the main body 1 has a porous structure and the included angle between two adjacent folded blades 11 is selected to be 10°-15°, due to the surface tension of water, the water adheres to the pores, so the liquid hardly flows, thereby increasing the residence time of the liquid on the evaporation curtain.

[0035] The folding evaporator curtain 5 also includes a straight section 2 integrally connected to the main body 1. On the left and right sides of the straight section 2, there is an installation component 3 for fixing the evaporator curtain and facilitating its installation onto the bracket 6. When the two installation components are installed onto the bracket, the straight section can be pulled flat from the left and right sides, so that the straight section acts as a load-bearing beam, supporting the evaporator curtain and preventing it from bending downwards.

[0036] The mounting assembly 3 includes a first clamping piece 31 and a second clamping piece 32 respectively located on the front and rear sides of the straight section 2. The first clamping piece 31 has multiple pins 311, and the second clamping piece 32 has multiple insertion holes 321 for accommodating the pins 311. The first clamping piece 31 and the second clamping piece 32 clamp the straight section 2 from the front and rear sides. The pins 311 pass through the holes in the straight section 2 and extend into the insertion holes 321, thereby fixing the straight section 2. The first clamping piece 31 and the second clamping piece 32 are fixedly connected by a locking mechanism. One of the first clamping piece 31 and the second clamping piece 32 is provided with a connector for easy installation onto the bracket 6. When the pins 311 are inserted into the evaporation curtain, they can fix the evaporation mesh.

[0037] The locking mechanism is either a snap-fit ​​structure (322) or a bolt structure. There may be two or more snap-fit ​​mechanisms.

[0038] The connector is a screw 312 fixedly connected to the first clamp 31 and the second clamp 32. The screw 312 is fixed to the bracket 6 by a nut 7. The tension of the straight section can be adjusted by rotating the nut.

[0039] One of the first clamping piece 31 and the second clamping piece 32 is provided with a guide pin 323, and the other of the first clamping piece 31 and the second clamping piece 32 is provided with a guide hole 313 that mates with the guide pin 323. The mate between the guide pin 323 and the guide hole 313 mainly serves to guide the installation.

[0040] The main body 1 is equipped with connecting ropes 4 that pass through each folding blade 11. Several spaced nodes 41 or fasteners are provided on the connecting ropes 4, thus forming a folding unit by assembling the same number of folding blades 11. The nodes 41 are formed by knotting the connecting ropes 4, or by attaching fasteners, such as metal wires, to the connecting ropes 4. The function of these nodes or fasteners is to hold the corresponding folding blades 11 in place. Preferably, ten folding blades 11 are tied together at one node 41, thus forming multiple folding units. These folding units are relatively independent, preventing the evaporation curtain from bending downwards. Simultaneously, the included angle of the folding blades remains between 10° and 15° under the influence of gravity from the folding curtain and the attached water.

[0041] The upper end of the connecting rope 4 is fixedly connected to the mounting component 3. There are two connecting ropes 4, which are located on the left and right sides of the main body 1. As the two connecting ropes 4 extend from top to bottom, they gradually tilt towards the center line 12 of the main body 1. Since the folding blades 11 of the evaporator curtain are more prone to bending at the lower end, the connecting ropes 4 are tilted towards the center line 12 at the lower end to further reduce the possibility of the evaporator curtain bending.

[0042] Example 2

[0043] See Figures 6 to 7 This illustrates another embodiment of the present application, an evaporation curtain assembly, including a bracket 6 and a plurality of the aforementioned folding evaporation curtains 5. The bracket 6 includes two side rods 61 spaced apart from each other and a crossbar 62 that fixes the two side rods 61 together. The folding evaporation curtains 5 are mounted to the two side rods 61 via mounting components 3 on their left and right sides. The two mounting components 3 straighten the straight portion 2 of the folding evaporation curtain 5. The screws 312 on the mounting components 3 are connected to nuts 7.

[0044] The bracket 6 adopts a combination of two side rods 61 and a crossbar 62, so that there is almost no obstruction above the evaporation curtain, resulting in high evaporation efficiency. Moreover, by straightening the straight part 2 through two mounting components 3, the straight part 2 forms a beam-like result, which can prevent the evaporation curtain from bending downward.

[0045] Example 3

[0046] See Figure 8 This illustrates another embodiment of the present application, which differs from Embodiment 2 in that:

[0047] A heat-absorbing net 8 is provided above each folded evaporation curtain 5, and multiple capillary tubes 9 located between two adjacent folded evaporation curtains 5 and extending into the evaporation pool 10 are fixedly connected to the heat-absorbing net 8.

[0048] The capillary tubes have a capillary effect, which can guide the liquid in the evaporation tank below to the heat absorption net for auxiliary evaporation. They can also make the most of the space between the two folded evaporation curtains. The heat absorption net is coated with a heat absorption layer, which has a high temperature and can increase the upward airflow, further improving the evaporation effect.
