Description

Technical Field

[0001] The present invention relates to a fully automatic dewaxing system, in particular to a fully automatic dewaxing system applied to the technical field related to steam dewaxing. Background Art

[0002] The steam dewaxing kettle is used for steam dewaxing of mold shells. It consists of a steam generator and an integrated dewaxing chamber. The steam generator is insulated both inside and outside, and it dissipates heat to the walls of the dewaxing chamber (dewaxing liner), so that the dewaxing chamber does not need to be heated separately. In this process, steam enters the dewaxing chamber directly within a few seconds. Since the mold shell has a high heat capacity, the hot steam quickly melts the wax before it expands.

[0003] The specification of Chinese patent CN104889324B discloses a steam dewaxing kettle and a dewaxing method based on the device. However, in the patent, when the dewaxing equipment is filled with steam, it is directly filled into the cavity, which is easy to cause direct blowing to the shell to be dewaxed. Not only is it easy to cause local damage to the shell, but also because the steam diffuses from point to body after entering the working chamber, the steam diffusion speed is slow, making it difficult to quickly and evenly distribute in the working chamber, resulting in uneven dewaxing of the shell as a whole, low dewaxing efficiency and other problems. Summary of the invention

DETAILED DESCRIPTION

[0017] Three implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0018] The first implementation method: Figure 1-2The figure shows a fully automatic dewaxing system, including an outer frame 11, a dewaxing kettle body 2 located in the outer frame 11, a condensed water treatment system 12, an automatic water replenishment system 13, a wax collection system 14 and a kettle door switch hydraulic station 15. The upper end of the outer frame 11 is fixedly connected with an exhaust hood 16, and the exhaust hood 16 is located just above the mouth of the dewaxing kettle body 2. The dewaxing kettle body 2 includes a steam generating chamber 21, a dewaxing liner 23 located in the steam generating chamber 21, and a sealing cover 22 rotatably mounted at the mouth of the steam generating chamber 21. The steam generating chamber 21 is also provided with a heating system for heating water and generating steam. The mouth of the dewaxing liner 23 is connected to the steam generating chamber 21. The mouth of the steam generating chamber 21 is fixed, and multiple water inlet holes 201 are fixedly connected to the outer ends of the steam generating chamber 21. The water inlet holes 201 are communicated with the automatic water replenishment system 13 through a water pipe. An energy recovery system 17 is also installed on the upper end. The upper end of the dewaxing liner 23 is communicated with the energy recovery system 17 through a steam outlet pipe. The steam outlet pipe is fixedly connected to the steam generating chamber 21. Two steam pipes 24 are fixedly connected to the upper end of the sealing cover 22. The ends of the two steam pipes 24 are respectively located on the front and rear sides of the sealing cover 22, and the ends of the steam pipes 24 are fixedly connected to the steam generating chamber 21 and are fixedly connected to the corresponding positions of the dewaxing liner 23. Figure 3 , the dotted arrow in the figure indicates the running direction of the steam, the front and rear inner walls of the dewaxing liner 23 are fixedly connected with steam guide strips 4, the two steam pipes 24 correspond to the middle parts of the two steam pipes 24 respectively, and the inner wall of the dewaxing liner 23 is fixedly connected with a wax liquid container 3, and the wax liquid container 3 is located below the two steam guide strips 4; like Figure 4 The lower end of the steam generating chamber 21 is fixedly connected with an external drain pipe 204, the bottom of the dewaxing inner tank 23 is fixedly connected with an internal drain pipe 203, the internal drain pipe 203 and the external drain pipe 204 are respectively connected with the condensate treatment system 12 through the liquid guide pipe, and the bottom of the wax liquid container 3 is fixedly connected with a wax drain pipe 202, and the wax drain pipe 202 is connected with the wax collection system 14 through the wax guide pipe; When in use, the mold shell is transported to the dewaxing kettle body 2 by the mold shell transport trolley and placed on the wax liquid container 3. The automatic water replenishment system 13 automatically replenishes water into the steam generating chamber 21. Under the action of the heating system, steam is generated. The steam enters the dewaxing inner tank 23 along the two steam pipes 24. Under the action of the steam, the wax on the mold shell is melted and falls off, and falls into the wax liquid container 3, and then discharged along the wax drain pipe 202 to the wax collection system 14 for storage. At the same time, the condensed water generated in the dewaxing inner tank 23 is discharged along the internal drain pipe 203 to the condensed water treatment system 12 for storage, and some of the unliquefied steam goes up to the energy recovery system 17 for heat recovery.

[0019] like Figure 5The steam guide strip 4 includes a redirecting cover 41, two end covers 42 fixedly connected to the two ends of the redirecting cover 41, and a steam dividing strip 43 fixedly connected to the inner wall of the middle part of the redirecting cover 41. The middle part of the steam dividing strip 43 is directly facing the mouth of the external drainage pipe 204. When the steam reaches the dewaxing liner 23 along the external drainage pipe 204, it will directly impact the steam dividing strip 43. Under the action of the steam dividing strip 43, the steam is dispersed to both sides. The horizontal cross-section of the steam dividing strip 43 is a triangle, and one of the ridges of the steam dividing strip 43 is perpendicular to the central axis of the mouth of the external drainage pipe 204. Figure 6 , the end surface of the redirecting cover 41 close to the dewaxing liner 23 is cut, and the inclined surface formed after the cut does not contact the inner wall of the dewaxing liner 23, so there is a gap between the redirecting cover 41 and the dewaxing liner 23, so that the steam dispersed on both sides of the steam dividing strip 43 can overflow along the gap along the inner wall of the dewaxing liner 23, thereby realizing the rapid dispersion of the steam, so that the initial overflow range in the dewaxing liner 23 is larger, which is a surface-body diffusion. Compared with the point-body diffusion of the prior art, the uniform distribution of the steam in the dewaxing liner 23 is greatly accelerated, so that the dewaxing efficiency and uniformity are significantly improved; like Figure 7 The wax liquid container 3 includes a liquid storage bin 31, a sieve plate 32 fixedly connected to the upper port of the liquid storage bin 31, and connecting strips 33 fixedly connected to the front and rear ends of the liquid storage bin 31. The cross-section of the connecting strip 33 is a broken line, and the ends of the two connecting strips 33 away from each other are fixedly connected to the corresponding inner walls of the dewaxed liner 23, respectively. The liquid storage bin 31 is in the shape of a boat, and the liquid storage bin 31 does not contact the inner wall of the dewaxed liner 23, so that there is a gap between the two, which is convenient for the water condensed in the dewaxed liner 23 to flow to the bottom and be discharged through the internal drain pipe 203. The left and right edges of the liquid storage bin 31 are fixedly connected with liquid blocking strips 301, and the distance between the two steam guide strips 4 is not less than the distance between the horizontal sections of the two connecting strips 33, which effectively ensures that when the mold shell is placed on the wax liquid container 3, the redirection cover 41 is not easy to block the mold shell.

[0020] In the above-mentioned fully automatic dewaxing system, through the setting of the steam guide strip 4, the steam can be effectively guided to overflow along the wall of the dewaxing inner tank 23. Compared with the existing technology, the occurrence of direct blowing can be effectively avoided. At the same time, the steam can be effectively diffused, and the diffusion of steam in the dewaxing inner tank 23 can be accelerated, so that the steam in the dewaxing inner tank 23 can be more quickly evenly distributed, effectively improving the uniformity and efficiency of dewaxing.

[0021] The second implementation method: Based on the first embodiment, this embodiment adds a wall-mounted steam dissipation fan 6, and the rest of the parts are consistent with the first embodiment.

[0022] Figure 8As shown in the figure, the black arrow represents the flow path of the wax liquid, b represents the mold shell to be dewaxed, an air gathering hood is fixedly connected between the upper end inclined surface of the steam guide strip 4 and the inner wall of the dewax liner 23, and two wall-attached steam dispersion fans 6 are also fixedly connected to the inner wall of the dewax liner 23. The two wall-attached steam dispersion fans 6 are respectively fixed to and communicated with the two air gathering hoods, and the two are symmetrical about the vertical center line of the wax liquid container 3.

[0023] like Figure 9-10 The wall-mounted steam dissipation fan 6 includes a hollow wall-mounted arc piece 61 fixed to the inner wall of the dewaxed inner tank 23 and a plurality of hollow overlapping arc pieces 62 respectively fixedly connected to the hollow wall-mounted arc piece 61 on the surface of the central axis of the dewaxed inner tank 23. The hollow wall-mounted arc piece 61 and the hollow overlapping arc piece 62 are both arc-shaped, and the widths of the ends of the two gradually decrease from top to bottom. Among the two adjacent hollow overlapping arc pieces 62, the lower end of the upper hollow overlapping arc piece 62 is fixedly extended to the interior of the lower hollow overlapping arc piece 62. The hollow overlapping arc piece 62 is provided with two openings, one opening is located at the contact point between the hollow overlapping arc piece 62 and the hollow wall-mounted arc piece 61, and the other opening is located at the upper end of the hollow overlapping arc piece 62. After the steam enters the steam guide strip 4, part of the steam flows along the bottom of the steam guide strip 4 and the dewaxed inner tank 23. The gaps between the wax inner liner 23 and the holes on the end cover 42 diffuse into the dewaxing inner liner 23, while another part of the steam goes up along the gas collecting hood and enters the wall-attached steam dissipation fan 6, and overflows from a plurality of arc-shaped hollow overlapping arc pieces 62 along the wall-attached steam dissipation fan 6. Since the hollow overlapping arc pieces 62 are arc-shaped and attached to the surface of the dewaxing inner liner 23, the steam overflowing from the wall-attached steam dissipation fan 6 is arc-shaped and inclined upward as a whole, so that direct blowing is not likely to occur between the mold shell, and the overflow range of the steam is further expanded. At the same time, the steam overflowing from the external drain pipe 204 overflows through a plurality of wall-attached steam dissipation fans 6 again, and the speed and impact force of the steam are buffered during the redirection process, so that the instantaneous impact force when it is ejected is greatly reduced, thereby effectively avoiding damage to the adjacent mold shell.

[0024] The part of the hollow overlapping arc piece 62 that does not overlap with the adjacent hollow overlapping arc piece 62 is provided with a variable mouth piece 621, and a variable layer 622 is fixedly connected between the variable mouth piece 621 and the hollow overlapping arc piece 62. The variable layer 622 is made of a flexible material, and the variable mouth piece 621 is made of metal iron. The part corresponding to the hollow overlapping arc piece 62 and the variable mouth piece 621 is installed with an electromagnetic sheet. There is an adsorption force between the electromagnetic sheet and the variable mouth piece 621 after power is turned on. When actually needed, multiple electromagnetic sheets can be controlled to be powered on and adsorbed. The variable mouth piece 621 causes the variable layer 622 to deform accordingly until the variable mouth piece 621 contacts the hollow overlapping arc piece 62. At this time, the mouth of the hollow overlapping arc piece 62 is blocked. By controlling whether multiple electromagnetic pieces are energized, the number of hollow overlapping arc pieces 62 that can overflow steam can be effectively controlled. Based on this, the initial diffusion range of the steam and the pressure when the steam is ejected are regulated. The more hollow overlapping arc pieces 62 with open mouths are, the smaller the pressure when the steam is ejected is and the larger the initial diffusion range is.

[0025] In summary, through the setting of the steam guide strip 4, the steam can be diverted and effectively guided to overflow along the wall of the dewaxing liner 23. Compared with the prior art, the direct blowing phenomenon can be effectively avoided, and at the same time, the initial distribution range of the steam can be effectively increased, so that the diffusion of the steam presents a surface-body state. Compared with the point-body diffusion in the prior art, the diffusion of steam in the dewaxing liner 23 is effectively accelerated, so that the steam distribution quickly tends to be uniform, and the uniformity and efficiency of dewaxing are effectively improved; in addition, with the setting of the wall-attached steam dispersion fan 6, the range of steam overflow along the wall can be further increased, and the uniform distribution speed of the steam can be further accelerated. At the same time, the impact force of the steam when entering the dewaxing liner 23 can be effectively reduced, and the influence of the impact force generated by the steam on the mold shell can be further reduced, thereby ensuring the rapid, efficient and uniform dewaxing of the mold shell.

[0026] The third implementation method: This embodiment is based on the second embodiment, and a monitoring middle strip 5 is added, and the rest of the parts are consistent with the second embodiment.

[0027] like Figure 11-13 The cross section of the sieve plate 32 is concave, and a monitoring middle strip 5 is fixedly embedded in the middle of the sieve plate 32. The monitoring middle strip 5 includes multiple monitoring strips 51, a liquid separation strip 52 fixedly connected between adjacent monitoring strips 51, and a liquid separation strip 52 installed inside the monitoring strip 51. The middle cross section of the liquid separation strip 52 is triangular, and liquid drop holes 302 are drilled at both ends of the liquid separation strip 52. The laser rangefinder 53 corresponds to the top of the liquid separation strip 52 and is higher than the top of the liquid separation strip 52, and the emission ends of the multiple laser rangefinders 53 are all facing the same direction.

[0028] In the present embodiment, as steam dewaxing proceeds, part of the wax liquid will gather in the middle of the sieve plate 32, filling the gap between the two monitoring strips 51 with the wax liquid. At this time, the distance data obtained by the laser rangefinder 53 is relatively small. As the dewaxing time increases, the wax liquid and the mold shell are gradually separated, and the gap between the two monitoring strips 51 gradually cannot be blocked. At this time, the data obtained by multiple laser rangefinders 53 increase and tend to be consistent. The maximum data is the distance between two adjacent laser rangefinders 53. Based on this, the overall progress of dewaxing can be roughly judged, effectively avoiding incomplete dewaxing or dewaxing is completed but steam dewaxing is still continuing, which not only effectively ensures efficiency, but also effectively reduces energy consumption.

[0029] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
