Description

Technical Field

[0001] This utility model relates to the field of lithium bromide solution filtration, specifically a lithium bromide solution circulating filtration device. Background Technology

[0002] Lithium bromide solution is a colorless liquid formed by dissolving lithium bromide (LiBr) in water or organic solvents. It has low global warming potential (GWP) and environmentally friendly characteristics, and is widely used in refrigeration, air conditioning, and industrial fields. However, prolonged use of lithium bromide solution can lead to excessive internal impurities. To facilitate recycling, filtration is necessary, requiring a filtration device. The "Lithium bromide solution filtration device" disclosed in application number "202323384709.X" represents an increasingly mature technology. This device features a reasonable and compact structure, is easy to use, and effectively adsorbs and filters impurities in the lithium bromide solution, thereby purifying the solution and effectively improving the cooling effect of the unit. With the solution completely drained, the device achieves the purpose of filtering impurities from the solution during normal unit operation. It is simple in structure, flexible in movement, and reusable. However, this filtration device has the following drawbacks: while the filter element does effectively filter lithium bromide solution, the filtration effect achieved solely through the aforementioned structure is not significant. Therefore, it is necessary to provide a filtration device that facilitates multiple-cycle filtration and improves filtration efficiency. Furthermore, this filtration device is not conducive to stirring the solution, which may lead to lithium bromide solution deposition, affecting filtration efficiency. Therefore, it is necessary to provide a filtration device that facilitates stirring and improves filtration efficiency. Summary of the Invention

[0003] This invention provides a lithium bromide solution circulating filtration device, which aims to solve the problem that existing lithium bromide solutions are not convenient for multiple circulating filtration.

[0004] To achieve the above objectives, this utility model provides a lithium bromide solution circulating filtration device, including a filtration assembly and a stirring assembly;

[0005] The filter assembly includes a first cavity, a connecting neck fixedly installed at the upper end of the first cavity, a second cavity fixedly installed at the upper end of the connecting neck, a circulation pump installed on one side of the connecting neck, an inlet pipe and an outlet pipe respectively installed at the upper and lower ends of the circulation pump, glass fiber cotton installed inside the connecting neck, a base installed at the lower end of the first cavity, an activated carbon plate installed inside the first cavity, and a filter screen installed inside the second cavity.

[0006] The stirring assembly includes a mounting bracket installed on the upper end of the second cavity, a servo motor mounted on the upper end of the mounting bracket, a drive shaft mounted on the output end of the servo motor, and a plurality of stirring blades detachably mounted on the side surface of the drive shaft.

[0007] As a preferred embodiment of this utility model, a connecting flange is provided on one side of the first cavity and the second cavity, as well as at one end of the inlet pipe and the outlet pipe. The first cavity, the second cavity, the inlet pipe and the outlet pipe are all connected by the connecting flange. A fixing ring is installed on the side surface of the glass fiber cotton, and the fixing ring is installed inside the connecting neck.

[0008] As a preferred embodiment of this utility model, the inner wall of the second cavity is provided with an annular groove, and a retaining ring is fixedly connected to the side surface of the filter screen, the retaining ring being engaged inside the annular groove.

[0009] As a preferred embodiment of this utility model, a plurality of connecting plates are fixedly connected to the side surface of the first cavity, and each of the connecting plates has a screw hole on its surface. A plurality of lead screws are rotatably connected to the upper end of the base, and the lead screws are threaded into the inside of the screw holes.

[0010] As a preferred embodiment of this utility model, a positioning ring is fixedly connected to the upper end of the base, the positioning ring is engaged inside the first cavity, and a sealing groove is provided at the upper end of the base, the first cavity is engaged inside the sealing groove.

[0012] In a preferred embodiment of this invention, the filter screen is made of stainless steel.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. When filtering lithium bromide solution, the lithium bromide solution is first transported from the second chamber. At this time, the lithium bromide solution passes through the filter screen, glass fiber cotton, and activated carbon plate in sequence and falls to the bottom of the first chamber. At this time, the stainless steel filter screen can filter large particles of impurities in the lithium bromide solution, while the glass fiber cotton can filter small particles. Finally, the microporous structure of the activated carbon plate can filter the lithium bromide solution multiple times. When the lithium bromide solution is not completely filtered, the circulation pump is started to extract the solution from the bottom of the first chamber through the outlet pipe and transport it back into the second chamber through the inlet pipe for secondary filtration. Compared with the filtration device in the existing "lithium bromide solution filtration device", this utility model can perform multiple circulation filtration operations on the lithium bromide solution as needed through the above-mentioned structure, thereby improving the filtration quality and enhancing the practicality of the filtration device.

[0015] When stirring the lithium bromide solution, simply start the servo motor to rotate the drive shaft, which in turn rotates several stirring blades on the side surface of the drive shaft. This ensures that the lithium bromide solution is in an active state, prevents sedimentation, and accelerates the filtration process. Compared with the filtration device in the existing "lithium bromide solution filtration device", this invention, through the cooperation of the above structures, facilitates the stirring of the lithium bromide solution, thereby improving the filtration efficiency.

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.

[0022] Example 1

[0023] Please see Figures 1-4 This utility model provides a lithium bromide solution circulation filtration device, including a filtration component 100 and a stirring component 200;

[0024] The filter assembly 100 includes a first cavity 101, a connecting neck 102 fixedly installed at the upper end of the first cavity 101, a second cavity 103 fixedly installed at the upper end of the connecting neck 102, a circulation pump 104 installed on one side of the connecting neck 102, an inlet pipe 105 and an outlet pipe 106 respectively installed at the upper and lower ends of the circulation pump 104, glass fiber cotton 107 installed inside the connecting neck 102, a base 108 installed at the lower end of the first cavity 101, an activated carbon plate 109 installed inside the first cavity 101, and a filter screen 110 installed inside the second cavity 103.

[0025] The stirring assembly 200 includes a mounting bracket 201 mounted on the upper end of the second cavity 103. A servo motor 202 is mounted on the upper end of the mounting bracket 201. A drive shaft 203 is mounted on the output end of the servo motor 202. Several stirring blades 204 are detachably mounted on the side surface of the drive shaft 203.

[0026] In one specific embodiment, the combination of the filter assembly 100 and the stirring assembly 200 not only facilitates multiple cyclic filtration operations of the lithium bromide solution, significantly enhancing the filtration effect and practicality of the filtration device, but also facilitates stirring of the lithium bromide solution, preventing sedimentation and thus improving the filtration efficiency. In use, the lithium bromide solution is first conveyed through the second chamber 103, and then the servo motor 202 is activated to rotate the drive shaft 203 and several stirring blades 204 on its side surface to stir the lithium bromide solution, thereby improving its filtration efficiency. With high filtration efficiency, when the lithium bromide solution passes through the filter screen 110, glass fiber cotton 107, and activated carbon plate 109 in sequence, the filter screen 110 can filter large particles in the lithium bromide solution, while the microporous structure of the glass fiber cotton 107 and activated carbon plate 109 can perform dual filtration of small particles. When the lithium bromide solution is not completely filtered, the circulation pump 104 is started in conjunction with the outlet pipe 106 to extract the lithium bromide solution in the first chamber 101 and re-transport it into the first chamber 101 through the inlet pipe 105 for secondary filtration. Therefore, the filtration quality can be improved and the practicality of the filtration device can be enhanced.

[0027] Please see Figure 2 and Figure 3 A connecting flange 111 is provided on one side of the first cavity 101 and the second cavity 103, as well as at one end of the inlet pipe 105 and the outlet pipe 106. The first cavity 101, the second cavity 103, the inlet pipe 105 and the outlet pipe 106 are all connected by the connecting flange 111. A fixing ring 112 is installed on the side surface of the glass fiber cotton 107. The fixing ring 112 is installed inside the connecting neck 102.

[0028] In one specific embodiment, the connecting flange 111 can enhance the sealing of the connection between the first cavity 101, the second cavity 103 and the liquid outlet pipe 106 and the liquid inlet pipe 105 respectively, ensuring the solution delivery efficiency, while facilitating the quick disassembly of the above structure. The retaining ring 112 can improve the stability of the glass fiber cotton 107 installed in the connecting neck 102.

[0029] Please see Figure 2 and Figure 3 The inner wall of the second cavity 103 is provided with an annular groove 121, and a retaining ring 122 is fixedly connected to the side surface of the filter screen 110. The retaining ring 122 is engaged inside the annular groove 121.

[0030] In one specific embodiment, the retaining ring 122 is engaged inside the annular groove 121, which can improve the ease of disassembly and replacement of the filter screen 110.

[0031] Please see Figure 2 and Figure 3A number of connecting plates 131 are fixedly connected to the side surface of the first cavity 101. Each of the connecting plates 131 has a screw hole 132. A number of lead screws 133 are rotatably connected to the upper end of the base 108. The lead screws 133 are threaded into the inside of the screw hole 132.

[0032] In one specific embodiment, by controlling the lead screw 133 to rotate clockwise or counterclockwise along the screw hole 132, the lifting and lowering of the first cavity 101 can be controlled, thereby cleaning the filter residue deposited on the upper end of the base 108 and improving ease of use.

[0033] Please see Figure 2 and Figure 3 A positioning ring 141 is fixedly connected to the upper end of the base 108. The positioning ring 141 is snapped into the inside of the first cavity 101. A sealing groove 142 is opened at the upper end of the base 108, and the first cavity 101 is snapped into the inside of the sealing groove 142.

[0034] In one specific embodiment, the positioning ring 141 is snapped into the first cavity 101 to improve the installation stability between the base 108 and the first cavity 101, while the sealing groove 142 can enhance the connection sealing between the first cavity 101 and the base 108.

[0035] Please see Figure 4 The output end of the servo motor 202 is fixedly connected to the limiting shaft 211. The upper end of the transmission shaft 203 is provided with a limiting hole 212. The limiting shaft 211 is inserted into the limiting hole 212. Several mounting blocks 213 are fixedly connected to the side surface of the transmission shaft 203. Several stirring blades 204 are inserted into the mounting blocks 213.

[0036] In one specific embodiment, the limiting shaft 211 is inserted into the limiting hole 212. When the servo motor 202 rotates the limiting shaft 211, it can rotate the transmission shaft 203 and several stirring blades 204 on its side surface, thereby stirring the lithium bromide solution.

[0037] Please see Figure 2 and Figure 3 The filter screen 110 is made of stainless steel.

[0038] In one specific embodiment, the stainless steel filter 110 can avoid corrosion by lithium bromide solution, thus extending its service life.

[0039] Working principle: In use, the lithium bromide solution is first conveyed through the second chamber 103. At the same time, the servo motor 202 is started to rotate the drive shaft 203, which in turn rotates several stirring blades 204 on the side surface to stir the lithium bromide solution, thereby improving the filtration efficiency. When the lithium bromide solution passes through the filter screen 110, glass fiber cotton 107 and activated carbon plate 109 in sequence, the filter screen 110 can filter large particles in the lithium bromide solution, while the microporous structure of the glass fiber cotton 107 and activated carbon plate 109 can perform double filtration of small particles. When the lithium bromide solution is not completely filtered, the circulation pump 104 is started in conjunction with the liquid outlet pipe 106 to extract the lithium bromide solution in the first chamber 101 and re-transport it into the first chamber 101 through the liquid inlet pipe 105, thereby performing secondary filtration of the lithium bromide solution, thereby improving the filtration quality and enhancing the practicality of the filtration device.
