Description

Technical Field

[0001] The invention belongs to the technical field of wax mold recovery and separation, and in particular relates to a wax recovery and processing device for valve casting. Background Art

[0002] At present, the valve casting wax mold is first made into a model of the valve casting to be made with wax material, and the model is welded to the gate rod with the same material to form a module. The surface of the module is dipped in refractory coating. After it is dried and solidified, the module is heated to remove the wax from the gate to form an empty shell. The empty shell is roasted to make it a solid mold shell, and liquid metal is poured from the gate. After condensation, it becomes a metal casting. When separating the wax material, the wax material is generally placed in a heating pool for heating, and the wax material is automatically removed after being heated. However, the wax model is placed in the heating pool by manual feeding. Due to the high temperature of the heating pool, it is not easy to collect the melted wax.

[0003] The existing Chinese patent document with publication number CN111992668A proposes to solve the above problem by using a heating box to heat the wax inside the wax model to completely melt the wax, which flows into the bottom of the wax storage pool. After reaching the wax recovery work station, the wax is sucked into the wax storage box with a special pump. However, if the wax is directly recovered after it is melted, it will contain impurities such as metal fragments, sand, and soil, and the purity of the recovered wax will be insufficient.

[0004] Therefore, the present invention proposes a wax recovery and processing device for valve casting, which solves the problem in the prior art that the wax will contain impurities such as metal fragments, sand, and soil when directly recovered after being melted, resulting in insufficient purity of the recovered wax. The wax is heated to melt, filtered to remove impurities, and then evaporated and purified to achieve the purpose of recovering high-purity wax for secondary use. Summary of the invention

DETAILED DESCRIPTION

[0030] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] For example, see Figures 1 to 12The present invention provides a technical solution: it includes a wax mold heating and melting barrel 1, a sealing cover 2 is arranged on the top of the wax mold heating and melting barrel 1, a guide cover 3 is arranged inside the wax mold heating and melting barrel 1, a liquid wax evaporation recovery barrel 4 is arranged on one side of the wax mold heating and melting barrel 1, a spray cooling component 5 is arranged above the liquid wax evaporation recovery barrel 4, a cooling liquefied metal cover 6 is fixedly installed above the inner surface of the liquid wax evaporation recovery barrel 4, a sealing groove matched with the sealing ring above the wax mold heating and melting barrel 1 is arranged on the lower surface of the sealing cover 2, a motor 21 is fixedly installed on the top of the sealing cover 2, and a rotating clamping joint 211 is rotatably installed in the middle of the lower surface of the sealing cover 2. The upper end of the rotating shaft of the rotating card joint 211 is fixedly connected to the output shaft of the motor 1 21, and the heating coil 22 is fixedly installed on the lower surface of the motor 1 21. A mounting guide column 33 is provided in the middle of the air guide cover 3, and the bottom end of the mounting guide column 33 is rotatably connected to the bottom of the inner surface of the liquid wax storage inner barrel 11. The top of the mounting guide column 33 is provided with a mounting card groove adapted to the rotating card joint 211. A wax mold placement rack 31 is provided above the air guide cover 3, and the middle inner wall of the wax mold placement rack 31 is clamped with the outer surface of the mounting guide column 33. A filter cover net 32 ​​is clamped and installed below the air guide cover 3, and the middle of the filter cover net 32 ​​is provided with a mounting card groove adapted to the rotating card joint 211. The wax mold heating and melting barrel 1 is provided with a movable groove adapted to the column 33; in the present embodiment, the liquid wax storage inner barrel 11 inside the wax mold heating and melting barrel 1 is used to store liquid wax, and the wax mold placement rack 31 is clamped and installed on the upper outer surface of the installation guide column 33, and the valve casting module is placed upside down on the inverted column 311 to make it evenly arranged on the wax mold placement rack 31, and then the sealing cover 2 is used to close the wax mold heating and melting barrel 1 to ensure that the rotating clamping joint 211 and the installation guide column 33 are accurately clamped, and the motor 21 and the heating coil 22 are started. The motor 21 drives the rotating clamping joint 211 to rotate so that the wax mold placement rack 31 rotates along with the installation guide column 33, and the heating coil 22 The valve casting module on the wax model placement rack 31 is roasted from above to melt the wax model and flow out. The wax model placement rack 31 rotates to use centrifugal force to make the wax liquid flow out faster. The guide cover 3 is funnel-shaped to centrally guide the wax liquid so that it passes through the filter cover net 32 ​​clamped inside the guide cover 3 for filtering, and most of the impurities are filtered out. The wax liquid enters the liquid wax storage barrel 11 for storage. After opening the sealing cover 2 and taking out the wax model placement rack 31, the filter cover net 32 ​​can be taken out to clean it, which is convenient to use. This solves the problem in the prior art that the wax is directly recovered after it is melted and contains impurities such as metal fragments, sand, and soil, resulting in insufficient purity of the recovered wax.

[0032] For example 2, please refer to Figures 1 to 12On the basis of the first embodiment, in order to make it easier for the wax liquid to flow out completely when it melts and reduce the loss, the present embodiment further proposes that arc-shaped scrapers are added on both sides of the inverted column 311, and the middle part of the arc-shaped scraper is movably connected by a quadrilateral metal rod, and a spring piston and an extrusion column are arranged at the upper and lower ends of the middle connection of the quadrilateral metal rod; in the present embodiment, when the valve casting module is installed, the quadrilateral metal rod is deformed so that the spring piston is squeezed out of the extrusion column, and at this time, the arc-shaped scraper shrinks inwardly to facilitate the inverted installation of the valve casting module on the inverted column 311, and the valve casting module is installed. The influence of gravity squeezes the extrusion column to reset the spring piston and squeeze the quadrilateral metal rod inward so that the arc scraper contacts the inner wall of the valve casting module. As the wax mold placement rack 31 rotates, relative friction and rotation occur between the valve casting module and the inverted column 311. At this time, the arc scraper will scrape the inner wall of the valve casting module to make the wax liquid melt and easier to discharge, thereby reducing the loss of wax recovery and improving the efficiency of wax liquid discharge. This further solves the problem in the prior art that the wax contained impurities such as metal fragments, sand, and soil when directly recovered after melting, resulting in insufficient purity of the recovered wax.

[0033] For example 3, please refer to Figures 1 to 12 On the basis of the second embodiment, in order to make the installation guide column 33 drive the wax model placement rack 31 to rotate more smoothly, this embodiment also proposes to add a ball on the upper inner wall of the air deflector 3, and the ball is movably installed on the upper inner wall of the air deflector 3, and at the same time, a slide rail compatible with the ball is added on the outer side of the lower surface of the wax model placement rack 31; in this embodiment, when the installation guide column 33 drives the wax model placement rack 31 to rotate on the air deflector 3, the ball rolls in the slide rail, and the sliding friction between the air deflector 3 and the wax model placement rack 31 is converted into rolling friction, so that the rotation of the wax model placement rack 31 is smoother, the energy consumption of the motor 21 is reduced, and it is easier to use centrifugal force to throw out the wax liquid, which further solves the problem in the prior art that the wax is directly recovered after it is melted, and the impurities such as metal fragments, sand, and soil inside will result in insufficient purity of the recovered wax.

[0034] Example 4, please refer to Figures 1 to 12On the basis of the third embodiment, in order to further purify the wax liquid, the present embodiment further proposes that a liquid wax storage inner barrel 11 is provided inside the wax mold heating and melting barrel 1, a waste heat recovery water channel 12 is provided between the outer surface of the liquid wax storage inner barrel 11 and the inner surface of the wax mold heating and melting barrel 1, a drain pipe 121 is fixedly installed at the bottom of the waste heat recovery water channel 12, a liquid wax discharge pump 13 is provided below the liquid wax storage inner barrel 11, the upper outer surface of the extraction pipe of the liquid wax discharge pump 13 is fixedly connected to the bottom inner wall of the liquid wax storage inner barrel 11, a wax liquid receiving plate 41 is fixedly installed in the middle of the liquid wax evaporation recovery barrel 4, a wax liquid discharge pipe 42 is provided at the lowest point of the wax liquid receiving plate 41, one end of the wax liquid discharge pipe 42 is fixedly connected to the inner wall of the wax mold heating and melting barrel 1, an evaporation heating device 43 is provided below the liquid wax evaporation recovery barrel 4, an evaporation pot 431 is provided inside the evaporation heating device 43, a slag discharge pipe is provided at the bottom rear side of the evaporation pot 431, and a spray nozzle is provided at the bottom of the evaporation recovery barrel 4. The shower cooling assembly 5 includes a motor 2 51 fixedly mounted on one side of the upper surface of the liquid wax evaporation recovery barrel 4, a driving gear 511 is fixedly mounted on the lower end of the output shaft of the motor 2 51, a rotating spray pipe 52 is rotatably mounted on the middle part of the top of the liquid wax evaporation recovery barrel 4, a gear 2 521 matched with the driving gear 511 is fixedly mounted on the outer surface of the rotating spray pipe 52, a water pump 53 is fixedly mounted on the other side of the upper surface of the liquid wax evaporation recovery barrel 4, the output pipe end of the water pump 53 is movably sleeved with the inner surface of the rotating spray pipe 52, a spray branch pipe 522 is fixedly mounted on the lower inner side wall of the rotating spray pipe 52, and the spray branch pipe 522 is arranged above the cooling liquefied metal cover 6, a sealing ring 61 matched with the liquid wax evaporation recovery barrel 4 is fixedly mounted on the outer surface of the lower end of the cooling liquefied metal cover 6, a waste hot water discharge pipe 62 is fixedly mounted on the rear of the side wall of the liquid wax evaporation recovery barrel 4, and the lower end of the waste hot water discharge pipe 62 is fixedly connected to the side wall of the wax mold heating and melting barrel 1;In this embodiment, the liquid wax discharge pump 13 works to transport the wax liquid stored in the liquid wax storage barrel 11 to the evaporator 431 through the pipeline. The evaporation heating device 43 continues to heat the evaporator 431 to increase the temperature of the evaporator 431 to evaporate the wax liquid. The steam rises and is covered by the cooling liquefied metal cover 6. At this time, the water inlet pipe of the water pump 53 is connected to the water supply pipe to supply cold water to the filter cover net 32. The motor 51 drives the driving gear 511 to rotate. Because the driving gear 511 is meshed with the gear 521, the rotating spray pipe 52 rotates accordingly to cause the spray branch pipe 522 to spray and cool the top of the cooling liquefied metal cover 6, so that the steam is liquefied and attached to the lower surface of the cooling liquefied metal cover 6, and the wax liquid is highly purified. Because the structure of the cooling liquefied metal cover 6 The metal ring is an inner fold, so the liquid wax drips along the two sides of the cooling and liquefied metal cover 6 and collects on the wax receiving plate 41. The wax receiving plate 41 is tilted to facilitate the discharge of the liquid wax through the evaporation and heating device 43. The sealing ring 61 increases the sealing of the cooling and liquefied metal cover 6 to prevent water penetration. At the same time, the water sprayed on the cooling and liquefied metal cover 6 absorbs the heat of steam and enters the waste heat recovery waterway 12 through the waste hot water discharge pipe 62. The waste heat recovery waterway 12 is spiral, and the waste heat release preheats the liquid wax storage inner barrel 11 to achieve the purpose of waste heat recovery and reduce losses. It further solves the problem in the prior art that the wax will contain impurities such as metal fragments, sand, and soil when it is directly recovered after melting, resulting in insufficient purity of the recovered wax. ;

[0035] For example 5, please refer to Figures 1 to 12On the basis of the fourth embodiment, in order to make the wax heating steam generate and scrape and fall faster, the present embodiment further proposes that a stirring rod 523 is fixedly installed at the bottom of the rotating spray pipe 52, a stirring impeller 1 7 and a stirring impeller 2 71 are arranged inside the evaporator 431, the stirring impeller 2 71 is arranged below the stirring impeller 1 7, the inner wall of the stirring impeller 2 71 and the stirring impeller 1 7 are respectively fixedly connected to the outer surface of the stirring rod 523, a clamping plate 524 is fixedly installed on the upper outer surface of the stirring rod 523, a triangular ball support frame 5241 is fixedly installed on the upper surface of the clamping plate 524, a wax scraping plate 5242 is movably installed in the middle of the triangular ball support frame 5241, springs are arranged on both sides of the wax scraping plate 5242, an oblique support plate 5243 is movably installed below the wax scraping plate 5242, and a sliding ball matched with the clamping plate 524 is sleeved on the lower end of the oblique support plate 5243; in the present embodiment, the stirring impeller 1 7 is a folded edge design, which increases The turbulent fluid and the folded surface increase the shear force mixing and promote evaporation. The stirring impeller 71 is turbine-shaped to form a vortex, which improves the gas-liquid interface and is conducive to vaporization. The combined use can increase the evaporation rate. The stirring rod 523 rotates with the rotating spray pipe 52, and the clamping plate 524 plays the role of fixing the triangular ball support frame 5241. The wax scraping plate 5242 is supported by the oblique direction of the oblique support plate 5243. When rotating with the clamping plate 524, the liquid wax beads condensed on the lower surface of the cooling liquefied metal cover 6 are scraped and diverted to make them flow into the wax liquid receiving plate 41. The upper end of the wax scraping plate 5242 is movably connected with the triangular ball support frame 5241 and can be flexibly offset in conjunction with the inner folded surface of the cooling liquefied metal cover 6. The oblique support plate 5243 slides under the clamping plate 524 for limited cooperation, which further solves the problem in the prior art that the wax is directly recovered after melting, which contains impurities such as metal fragments, sand, and soil, and the purity of the recovered wax is not enough.
