Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of wax model processing technology, and in particular relates to a wax model wax water filtering and purifying device. Background Art
[0002] Casting is a common way to produce industrial accessories. Wax casting is not only environmentally friendly, but also suitable for casting workpieces with complex structures and high precision requirements.
[0003] The wax casting workpiece first needs to be prepared with the materials for making the wax model, which is specifically obtained by mixing organic glue (including organic materials such as latex, polymethacrylate, silane coupling agent, etc.) with inorganic materials (including refractory materials such as manganese oxide powder and silicon oxide powder) to obtain the slurry for making the wax model. By adding refractory inorganic materials, the stability of the wax model is improved.
[0004] After the wax model slurry (i.e. wax water) is prepared, the slurry needs to be filtered to intercept the large-particle materials that cannot be dissolved in the wax model (the wax water contains organic glue with greater bonding properties. During the preparation process, if it cannot be mixed evenly with the inorganic material in time, the slurry contains inorganic materials and glue inclusions formed during the dissolution and stirring process, which are lumpy in shape. The particle size of the inclusions varies depending on the degree of inclusion). However, during the filtration process, since the wax water contains high-density inorganic materials, the high-density inorganic materials are easily separated from the slurry during the filtration process, which seriously damages the uniformity of the wax water slurry.
[0005] In the actual working process, after the wax water is filtered from the filter structure, the inclusions in the wax water are retained, resulting in a lower concentration of the wax water slurry (the wax water becomes thinner than before filtration). After the concentration of the slurry system changes, the high-density inorganic materials settle out of the slurry. In order to keep the slurry homogenized again, it is necessary to stir and disperse it again. However, it is obvious that this method not only leads to an extra step in the production process of the wax water, but also requires many steps such as loading into the barrel, stirring, and unloading to stir and disperse the wax water again. The process is complicated and the efficiency is greatly reduced. Utility Model Content

[0030] The utility model has the following beneficial effects:
[0031] 1.

The above device is used to realize that when the slurry passes through the long filter tube, the slurry pushes the spiral pushing structure. When the spiral pushing structure is driven by the slurry, the slurry passes in a spiral downward flow manner. The spiral downward flow manner can stir the slurry to ensure that different systems in the slurry are kept mixed during the filtering process. Secondly, during the filtering, because the slurry is in a large flow state, the upper layer of the slurry will not be stationary on the filter screen plate. Therefore, this method further avoids the stratification of the slurry.
[0032] 2.

In this way, the particle size gradually becomes smaller and is dissolved and dispersed in the system. In this way, the system before and after filtration is kept similar, further ensuring that the system will not change due to excessive concentration of the material system, and the inorganic materials with high density will not precipitate.

[0044] Example 1
[0045] like Figure 1-6 As shown, a wax model wax water filtering and purification device includes a wax water pre-filtration refinement mechanism, and the wax water discharge end is connected to a wax water vortex filtering mechanism. The wax water vortex filtering mechanism is used to filter and push the wax water in a spiral manner during the wax water process, and a stirring force is formed during the spiral pushing of the wax water, thereby increasing the fluidity of the wax water fluid, thereby avoiding the stratification of high-density inorganic materials (refractory materials) and organic materials in the wax water.
[0046] Specifically, the wax water cyclone filtering mechanism includes a long filter tube 2 (the long filter tube 2 is installed at the bottom of the wax water refining cylinder of the wax water pre-filtering refining mechanism by threaded connection, which is convenient for subsequent disassembly and cleaning). At the same time, a plurality of filter screens 34 spaced apart from each other are fixedly connected in the long filter tube 2 (the filter screens 34 are made of thin steel plates, and filter holes are provided on the filter screens 34 in order to filter the wax water).
[0047] At the same time, the wax-water vortex filtration mechanism also includes a spiral pusher assembly 3 for promoting the filtration of wax water, and the spiral pusher assembly 3 includes a mesh plate 31 spaced apart from each other (a plurality of through holes 311 are provided on the mesh plate 31, and the slurry passes through the through holes 311, and the mesh plate 31 is fixedly installed in the lumen of the long filter tube 2), and a rotating shaft 32 is rotatably connected between the mesh plates 31 (according to the existing conventional method, a bearing is installed at the center of the mesh plate 31, and the rotating shaft 32 rotates on the bearing), and at the same time, the rotating shaft 32 passes through the filter mesh plate 34 (in actual work, a through hole matching the rotating shaft 32 is provided at the center of the filter mesh plate 34, and the rotating shaft 32 is rotatably connected to the through hole at the center of the filter mesh plate 34. At the same time, in order to allow the rotating shaft 32 to rotate freely, a gap is maintained between the rotating shaft 32 and the through hole, and the size of the gap is smaller than the hole gap of the filter holes on the mesh plate 31).
[0048] The rotating shaft 32 is fixedly connected to a plurality of spiral propulsion structures 33 spaced apart from each other in an upper and lower direction (the spiral propulsion structure 33 is installed in the following manner: a spiral blade is passed through the rotating shaft 32 and welded to the rotating shaft 32. In actual processing, a spiral propulsion structure 33 is welded, a filter screen plate 34 is inserted into the rotating shaft 32, and inserted into the long filter tube 2. The filter screen plate 34 is pre-cooled by thermal expansion and contraction, and then driven into the long filter tube 2. This process is repeated to form a multi-layer filtering structure in the upper and lower layers). The spiral propulsion structures 33 are respectively located above the filter screen plates 34.
[0049] During the filtering process, the slurry is pushed onto the spiral pushing structure 33 . Under the push of the spiral pushing structure 33 , the rotating shaft 32 rotates, and the slurry is kept uniform under the spiral stirring of the spiral pushing structure 33 .
[0050] Under the action of the filter screen plates 34 distributed up and down, layer-by-layer filtration is achieved. In the actual working process, in order to increase the filtration speed, the aperture size of the filter holes on the filter screen plates 34 can be set in a gradient distribution manner. Specifically, the aperture of the upper filter screen plate 34 is large, and the aperture of the lower filter screen plate 34 is small.
[0051] During the filtration process, as the materials included in the slurry are gradually retained, the dilution of the slurry becomes larger. During the filtration process, under the action of gravity, the high-density inorganic materials in the slurry are easily separated from the slurry, resulting in poor uniformity of the slurry. The above-mentioned device is used to realize that when the slurry passes through the long filter tube 2, the slurry pushes the spiral pushing structure 33. When the spiral pushing structure 33 is driven by the slurry, the slurry passes in a spiral downward manner. The spiral downward manner can, on the one hand, stir the slurry to ensure that different systems in the slurry remain mixed during the filtration process. On the other hand, during filtration, because the slurry is in a relatively large flow state, the upper layer of the slurry will not remain stationary on the filter mesh plate 34. Therefore, this method further avoids stratification of the slurry.
[0052] According to the conventional method, the upper end of the long filter tube 2 is connected with a valve.
[0053] Example 2
[0054] like Figure 1-6 As shown, based on the structure of Example 1, in order to further refine the slurry before filtration, improve the uniformity of the slurry, and avoid excessive changes in slurry concentration during filtration, which leads to serious stratification of the system, the top of the above-mentioned wax water refining cylinder 1 is detachably assembled and connected with a top material cover (the method is: a number of screws are fixed to the mouth of the wax water refining cylinder 1, which pass through the top material cover and are tightened with nuts), and the wax water pre-filtration refinement mechanism also includes a wax water slurry refinement component 4.
[0055] Specifically, the wax water slurry refinement assembly 4 includes a rotating motor 41 fixedly mounted at the top center of the top material cover. According to the existing conventional method, the rotating motor 41 is equipped with a stirring shaft rotatably connected to the wax water refinement cylinder 1 (the stirring shaft is rotatably connected to the bottom center of the wax water refinement cylinder 1 and staggered with the discharge hole at the bottom), and the stirring shaft is fixedly connected to a plurality of slurry abrasive components spaced apart from each other.
[0056] The slurry abrasive components are used to stir the slurry and to impact, rub and refine the coarse particles (mostly inorganic materials) and agglomerated particles in the slurry.
[0057] Specifically, the slurry abrasive component includes a plurality of grinding rods 42 assembled and connected to the stirring shaft (the grinding rods 42 are preferably made of lightweight aluminum alloy, and their outer surfaces are subjected to friction roughening treatment, and the roughened surfaces are used to contact the material slurry to achieve impact and uniform grinding of the material slurry).
[0058] Specifically, a plurality of connecting tubes 411 are welded on the stirring shaft, and a connecting screw is fixedly connected to the inner end of the grinding rod 42 , and the connecting screw is threadedly connected to the connecting tube 411 .
[0059] During the working process, after the slurry is pumped, the slurry is refined under the action of the high-speed rotating multi-layer grinding rod 42, especially the wrapped materials that are not fully dissolved, refined and dispersed in the slurry are gradually reduced in particle size and dissolved and dispersed in the system. In this way, the system before and after filtration is kept similar, further ensuring that the system is not changed due to excessive concentration of the material system, and the inorganic materials with high density are not precipitated.
[0060] The top material cover is connected with a plurality of pumping elbows for pumping materials, specifically, the first pumping elbow 11 and the second pumping elbow 12 on both sides are used for pumping materials.
[0061] Example 3
[0062] like Figure 1-6 As shown, in this embodiment, based on the structure of embodiment 2, the outer end of the grinding rod 42 is fixedly connected with a resistance rolling member, and the resistance rolling member includes a rolling ball seat 43 fixedly connected to the grinding rod 42, and the upper limit of the rolling ball seat 43 is provided with a resistance rolling ball 431. The resistance rolling member is used to keep the grinding rod 42 under resistance (reduce its gravity load) during the rotation process. Specifically, an inner filter cylinder 44 (the slurry abrasive component is located in the inner filter cylinder 44) is fixedly connected to the wax water refinement cylinder 1, and the resistance rolling ball rolls on the inner side wall of the inner filter cylinder 44. The inner filter cylinder 44 realizes the filtration of the entire system. It is made of stainless steel and maintains a spacing of 2 cm between it and the inner side wall of the wax water refinement cylinder 1, which is convenient for removing the slurry.
[0063] Specifically, the bottom of the inner filter cartridge 44 is sealed, and a plurality of slurry through holes are provided on the outer wall of the inner filter cartridge 44. At the same time, the inner filter cartridge 44 is suspended and installed in the wax water thinning cartridge 1, and a ring-shaped mounting plate is fixedly connected to the top of the inner filter cartridge 44, and a plurality of L-shaped mounting plates 441 are welded and connected to the annular mounting plate, and the mounting plates 441 are fastened to the inner wall of the wax water thinning cartridge 1 by bolts. According to the existing conventional method, the stirring shaft passes through the wax water thinning cartridge 1, and the stirring shaft is rotatably connected to the bottom center position of the wax water thinning cartridge 1.
[0064] During the working process, the slurry is distributed in the wax water refining cylinder 1 and the inner filter cylinder 44 , while the wrapped and agglomerated materials that cannot be refined are retained in the wax water refining cylinder 1 .
[0065] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
