Description

Technical Field

[0001] This utility model relates to the field of cyclone preventers, and more specifically to a high-efficiency filtrate cyclone preventer. Background Technology

[0002] A vortex suppressor, also known as a vortex eliminator or vortex inhibitor, is a device used in water treatment systems, fire protection systems, and other liquid transport pipelines. Its main function is to prevent water flow from forming vortices or eddies before entering sensitive equipment (such as water pumps), thereby protecting these devices from damage and ensuring stable system operation.

[0003] Existing vortex preventers, such as "Publication No.: CN204380879U, A Vortex Preventer", use a "circular cover with through holes" to disperse liquid flow and provide filtration through the through holes. However, during the flow process, the liquid continuously impacts the through holes for filtration as it flows through the cover. At this time, impurities of different sizes will continuously accumulate uniformly on the wall of the circular cover, resulting in the disadvantage of rapid accumulation and blockage of the through holes. Utility Model Content

[0004] The purpose of this utility model is to provide a high-efficiency filtrate cyclone preventer in order to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] This utility model proposes a high-efficiency filtrate cyclone preventer, including a through pipe and flanges and a diffuser device fixed to the two ends of the through pipe respectively;

[0007] The diffuser includes an upper plate, a lower plate located below the upper plate, and at least two sets of filtration assemblies fixed between the upper plate and the lower plate. The filtration assemblies are uniformly provided with multiple sets of filter holes.

[0008] Each set of filtration components forms a filtration chamber between the upper plate and the lower plate, that is, the at least two sets of filtration components form at least two sets of filtration chambers;

[0009] The at least two sets of filtrate chambers, one set of which is connected to the through pipe, and the remaining sets of filtrate chambers are arranged in concentric circles around the filtrate chamber connected to the through pipe. That is, the at least two sets of filtrate assemblies are concentric circles and the pore size of the filtrate assembly in the center gradually decreases outward.

[0010] The at least two sets of filtrate chambers, wherein each pair of adjacent filtrate chambers is connected only through filter holes on the filtrate assembly between the two sets of filtrate chambers.

[0011] As a preferred technical solution of this utility model, the filtrate assembly includes an annular mesh with one end fixed to the bottom end of the upper plate, multiple sets of reinforcing strips fixed around the annular mesh, a connecting plate fixed to the bottom end of the reinforcing strips, and several sets of fixing members for fixing and connecting the reinforcing strips and the lower plate. The bottom end of the annular mesh is fixed to the connecting plate, and multiple sets of mesh holes are evenly provided on the annular mesh.

[0012] In a preferred embodiment of this invention, the mesh is a filter mesh.

[0013] As a preferred technical solution of this utility model, the multiple sets of reinforcing strips are evenly distributed in a ring around the periphery of the ring mesh.

[0014] As a preferred embodiment of this utility model, the fixing member is provided in multiple sets and is evenly distributed on the lower plate.

[0015] The beneficial effects of this utility model are as follows:

[0016] By setting at least two sets of filtration chambers, when the fluid enters the innermost filtration chamber through the pipe, it flows through the filtration components and filtration chambers in an alternating manner. During this process, impurities are blocked by the filter holes, and the impurity particles are blocked in the at least two sets of filtration chambers in a concentric circle in descending order of size, thereby dispersing the accumulation of impurities, reducing the clogging rate, and improving the filtration efficiency. Impurity cleaning is also convenient. Attached Figure Description

[0020] like Figures 1-2 As shown, this utility model proposes: a high-efficiency filtrate cyclone preventer, including a through pipe 1 and flanges 2 and a diffuser 3 fixed to the two ends of the through pipe 1 respectively. The pipe ends of the through pipe 1 are oriented vertically. The flange 2 is fixed at the top of the through pipe 1 and the diffuser 3 is fixed at the bottom of the through pipe 1.

[0021] The diffuser 3 includes an upper plate 31, a lower plate 32 disposed below the upper plate 31, and at least two sets of filtration assemblies 33 fixed between the upper plate 31 and the lower plate 32. The filtration assemblies 33 are uniformly provided with multiple sets of filter holes, such as... Figure 2As shown, the filtrate assembly 33 is provided in three sets;

[0022] Each set of filtration components 33 forms a filtration chamber between the upper plate 31 and the lower plate 32, that is, the at least two sets of filtration components 33 form at least two sets of filtration chambers, such as Figure 2 As shown, the filtrate assembly 33 is similar to a ring shape, forming a filtrate chamber between the upper plate 31 and the lower plate 32 and between the ring-shaped filtrate assembly 33. When three sets of filtrate assemblies 33 are provided as described above, three sets of filtrate chambers are provided.

[0023] Of the at least two groups of filtrate chambers, one group is connected to the through pipe 1, and the remaining groups of filtrate chambers are arranged concentrically around the filtrate chamber connected to the through pipe 1, as shown below. Figure 2 As shown, two sets of annular filtrate chambers are arranged in sequence around the filtrate chamber connected to the bottom end of the tube 1, thereby forming multiple continuous spaces;

[0024] That is, the at least two sets of filtrate components 33 are concentric circles and the pore diameter of the filtrate component 33 in the center gradually decreases outwards. According to the above, the three sets of filtrate components 33 are concentric circles, and the pore diameter of the innermost filtrate component 33 gradually decreases outwards.

[0025] The at least two sets of filtration chambers are connected only through filter holes on the filtration assembly 33 between the two sets of filtration chambers. In this way, when the fluid (such as water) enters the innermost filtration chamber through the pipe 1, it flows through the filtration assembly 33 and the filtration chamber in an alternating manner. During this process, impurities are blocked by the filter holes, and the impurity particles are blocked in concentric circles in the three sets of filtration chambers in descending order of size, thereby dispersing the accumulation of impurities, reducing the clogging rate, and improving the filtration efficiency.

[0026] like Figures 1-2 As shown, the specific structure of the filtrate assembly 33 is as follows:

[0027] The filtrate assembly 33 includes an annular mesh 331 whose annular end is fixed to the bottom end of the upper plate 31. The annular mesh 331 can be a stainless steel woven mesh or a stainless steel annular plate, etc. The top end of the annular mesh 331 is fixed to the bottom end of the upper plate 31.

[0028] The ring mesh 331 is uniformly provided with multiple sets of mesh holes, that is, the stainless steel woven mesh is uniformly provided with multiple sets of woven holes or the stainless steel ring plate is uniformly provided with multiple sets of through holes.

[0029] Among them, the mesh is a filter hole, corresponding to the filter hole set above;

[0030] Multiple sets of reinforcing strips 332 are fixed around the periphery of the ring mesh 331. The reinforcing strips 332 with their ends facing up and down are fixed by welding or other means at the outer ring end of the ring mesh 331. The top of the reinforcing strips 332 is fixed to the bottom end of the upper plate 31.

[0031] Among them, multiple sets of reinforcing strips 332 are evenly distributed in a ring around the periphery of the ring mesh 331, and are reasonably distributed in the support position to improve the strength of the overall structure.

[0032] The bottom end of the reinforcing strip 332 is fixed to the connecting plate 333, and the bottom end of the ring mesh 331 is fixed to the connecting plate 333. The bottom ends of the reinforcing strip 332 and the ring mesh 331 are connected and reinforced to further improve the strength of the overall structure.

[0033] And several sets of fasteners 334 for fixing the reinforcing strip 332 and the lower plate 32. The fasteners 334 are bolts, which are threaded through the top and bottom ends of the reinforcing strip 332 and the lower plate 32 to fix the reinforcing strip 332 and the lower plate 32. The lower plate 32 has a recessed groove at the bottom end for the connecting bolts to be inserted. When the bolts are removed, the lower plate 32 can be removed to expose the filtrate chamber for easy cleaning of impurities and the annular mesh 331.

[0034] Among them, the fasteners 334 are provided in multiple sets and are evenly distributed on the lower plate 32 to achieve a uniform connection and improve the overall stability of the fixation.
