Description

Technical Field

[0001] The invention relates to the technical field of wax melting furnaces, in particular to a high-temperature material discharge pipe structure for a wax melting furnace. Background Art

[0002] During the shipbuilding process, wax melting furnaces are mostly used for launching ships from the slipway after they are built. When the ship is launched by gravity,

[0003] The longitudinal oiled slideway launch is a launching facility that integrates a slipway and a slipway. It has a long history and is durable. During the launching operation, a certain thickness of grease is first applied to the slipway to reduce friction. This grease was previously mostly made of butter, but is now often made from varying proportions of paraffin, stearic acid, and rosin. The ship then uses its own weight to move onto the slipway and slide, slides into the water along the slipway, and floats on the water surface due to its own buoyancy, completing the launch.

[0004] When using a wax melting furnace to melt wax, the temperature of the wax liquid can reach as high as 200 degrees Celsius. Ordinary wax melting furnaces use a discharge pipe connected to the side wall of the wax melting furnace to discharge the wax liquid. The discharge pipe is a hollow pipe, so when the high-temperature wax liquid is discharged, the material is easy to splash out and cause injuries to employees; secondly, due to the influence of the wax liquid level inside the wax melting furnace, the discharge speed of the wax liquid will also be different. That is, when the internal liquid level of the wax melting furnace is high, the static pressure in the bottom discharge pipe is high, so the flow rate of the wax liquid is faster when it is discharged, which is more likely to cause dangerous situations such as wax liquid bursting; conversely, when the wax liquid level in the wax melting furnace is low, the static pressure at the discharge pipe is low, and the initial discharge speed is relatively slow, which is relatively safer.

[0005] Because workers cannot easily observe the wax level when discharging the wax from the wax melting furnace, they cannot predict the wax discharge rate from the discharge pipe. Without sufficient experience in discharging and barreling, dangerous situations such as wax splashing and inaccurate discharging can easily occur during operation, causing unnecessary injuries to employees and product losses. In this context, it is necessary to propose a wax melting furnace high-temperature material discharge pipe structure to solve the above problems, ensuring discharge efficiency while also ensuring the personal safety of employees. Summary of the Invention

[0006] The purpose of the present invention is to solve the above technical problems and to provide a high-temperature material discharge pipe structure for a wax melting furnace.

[0007] To achieve the above objectives, the present invention adopts the following technical solutions: a wax melting furnace high-temperature material discharge pipe structure, comprising a wax melting furnace body, a discharge pipe connected to one side of the lower part of the wax melting furnace body, the end of the discharge pipe having a vertical pipe portion, and a swirl throttling structure provided in the vertical pipe portion;

[0008] The swirl throttling structure includes a fixed flow hole and a flip adjustment part. The flip adjustment parts are arranged at mirror-symmetrical positions on both sides of the vertical tube cross section. The gap formed by the distance between the two flip adjustment parts is the fixed flow hole.

[0009] The flip adjustment portion includes a flip plate, which is in the shape of a semicircular plate. The arc radius of the flip plate is the same as the radius of the vertical tube portion. The flip plate has a round side surface and a flat side surface. The round side surface is tightly attached to the inner wall of the vertical tube portion. The flat side surface has a flow clearance distance from the axis of the vertical tube portion. A sleeve shaft portion is provided perpendicular to the center of the flat side surface. The flip plate rotates along the axis of the sleeve shaft portion.

[0010] The flat side surfaces of the flip plates on both sides are arranged parallel to each other. When the flip plates are in a horizontal position, the flow gap distance between the two flat side surfaces is added together to form a fixed flow hole.

[0011] The cross rotation driving mechanism controls the flip plates on both sides to rotate in opposite directions with their respective sleeve shafts as axes, and when the two flip plates rotate, the planes where they are located are in a cross shape.

[0012] Furthermore, a liquid level signal acquisition mechanism is provided in the wax melting furnace body, the liquid level signal acquisition mechanism is connected to the input end of the controller, and the output end of the controller is connected to the cross-rotation mechanism.

[0013] Furthermore, the liquid level signal acquisition structure includes a signal float and a signal receiver coordinated with the signal float; the signal float includes a guide rod, a float, and a magnet, the guide rod is vertically fixed on the side of the wax melting furnace body close to the inner wall, the float is sleeved and slidably connected to the guide rod, the magnet is arranged on the outer side of the float, and the signal receiver is vertically fitted on the side wall of the wax melting furnace body to capture the magnetic field signal of the magnet and convert it into liquid level data and send it to the controller.

[0014] Furthermore, the vertical tube portion is provided with a fixed shaft along its diameter direction, and the two flip plates are rotatably connected to the fixed shaft through their respective sleeve shaft portions, and the two sleeve shaft portions are provided with driven bevel gears at one end close to each other.

[0015] Furthermore, the cross-rotation drive mechanism includes a drive shaft, a drive bevel gear, and a servo motor. The swirl throttling structure is arranged at the upper end of the vertical pipe portion near the elbow of the discharge pipe. A drive shaft is provided along the axis of the vertical pipe portion, and a shaft seat is provided at the midpoint of the fixed shaft. One end of the drive shaft is rotatably connected and placed in the shaft seat, and the other end of the drive shaft extends out of the outer wall of the elbow. A mounting platform is provided on the outer wall of the elbow. The servo motor is arranged on the mounting platform, and the output end of the servo motor is connected to the drive shaft. A drive bevel gear is fixed to the lower end of the drive shaft, and the two sides of the drive bevel gear are respectively meshed and connected with two driven bevel gears.

[0016] Furthermore, the upper end of the vertical tube portion is connected to the horizontal tube portion, the other end of the horizontal tube portion is connected to the wax melting furnace body, and the length direction of the fixed flow hole is perpendicular to the axial direction of the horizontal tube portion.

[0017] Furthermore, the vertical tube portion is provided with a swirl guide belt on the lower side of the swirl throttling structure.

The multiple swirl guide belts are centrally symmetrically arranged with respect to the axis of the vertical tube portion.

[0018] Furthermore, one end of the horizontal pipe portion is connected to the wax melting furnace body and a U-shaped continuous folding portion is provided in the wax melting furnace body.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. When the flip adjustment part of the present invention is in a horizontal state to form a fixed flow hole, the narrow long hole can form a throttling and speed-limiting effect on the vertical pipe part, which is used to limit the flow of the released high-temperature wax liquid when the liquid level in the wax melting furnace is high, thereby improving the safety of use.

[0021] 2. The length direction of the fixed flow hole is perpendicular to the horizontal pipe, which can deflect and reduce the speed of the wax liquid passing through the outer wall of the elbow at a high speed, thereby preventing the high-temperature wax liquid from directly flowing out through the fixed flow hole at a high speed, causing the risk of high-temperature wax liquid splashing.

[0022] 3. The flip plates on both sides are controlled by the cross-rotation drive mechanism to open in a cross shape at opposite angles, so that the two flip plates have a diversion effect on the passing wax liquid, promoting the wax liquid to rotate and fall close to the side wall of the vertical pipe.

[0023] 4. When the wax liquid level in the wax melting furnace is low, the discharge speed decreases, and the cross-rotation drive mechanism controls the flip plates on both sides to be in a vertical state, which greatly reduces the resistance in the pipeline and allows the wax liquid to flow out smoothly.

[0024] 5. The continuous return part can make the wax liquid flow back and forth in the tube, thereby reducing the impact force of the liquid during flow. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] Example 1:

[0034] A wax melting furnace high temperature material discharge pipe structure, such as Figure 1 As shown, it includes a wax melting furnace body 1, a drain pipe 2 is connected to one side of the lower part of the wax melting furnace body 1, and the drain pipe 2 includes a horizontal pipe part 21 and a vertical pipe part 3. The end of the drain pipe 2 is the vertical pipe part 3, and a swirl throttling structure 5 is provided in the vertical pipe part 3;

[0035] The swirl throttling structure 5 includes a fixed flow hole 4, a flip adjustment part, such as Figure 4 As shown, flip adjustment parts are provided at mirror-symmetrical positions on both sides of the cross section of the vertical pipe part 3, and the gap formed by the distance between the two flip adjustment parts is a fixed flow hole 4. It can be understood that the fixed flow hole 4 is formed by the flip adjustment parts on both sides being spaced a certain distance apart from each other. Different from the general regulating valve, the fixed flow hole 4 can make the vertical pipe part 3 of the discharge pipe 2 have at least a liquid flow channel of the size of the fixed flow hole 4, and as the flip adjustment part is controlled to rotate, the liquid flow rate of the vertical pipe part 3 can increase or decrease accordingly.

[0036] like Figure 2As shown, the flip adjustment portion includes a flip plate 6, which is in the shape of a semicircular plate. The arc radius of the flip plate 6 is the same as the radius of the vertical tube portion 3. In actual use, the arc side wall of the flip plate 6 in the horizontal state fits in with the inner wall of the vertical tube portion 3, so that the fitting place of the arc side and the vertical tube portion 3 can prevent the wax liquid from flowing through. The flip plate 6 has a round side surface and a flat side surface; the flat side surfaces of the flip plates 6 on both sides are arranged parallel to each other. When the flip plate 6 is in the horizontal position, the flat side surface has a flow gap distance from the axis of the vertical tube portion 3, and the flow gap distance between the two flat side surfaces is added to form a fixed flow hole 4; the fixed flow hole 4 is always kept in a normal state;

[0037] The round side surface is in close contact with the inner wall of the vertical tube 3. As the flip plate 6 rotates, it can be turned from a horizontal state ( Figure 3 (shown in a) to the vertical position ( Figure 3 As shown in c), it can be understood that when the flip plate 6 is in a horizontal state, the circular side wall fits the vertical tube portion 3; during the rotation process, the gap between the circular side wall and the side wall of the vertical tube portion 3 gradually increases and can be used for the wax liquid to pass through, and finally rotates to Figure 3 In the state shown in middle c, the flip adjustment part is fully opened, at which time the obstruction to the wax liquid is minimal, so that the discharge pipe 2 is close to the liquid flow rate of the cylindrical hollow pipe. Furthermore, the rotation angle of the flip adjustment part can be adjusted according to the height of the wax liquid level in the wax melting furnace body 1.

[0038] Example 2:

[0039] A sleeve shaft portion 7 is provided perpendicularly to the center of the flat side surface of the flip plate 6, and the flip plate 6 rotates along the axis of the sleeve shaft portion 7; further, the cross-rotation drive mechanism 8 controls the flip plates 6 on both sides to rotate in opposite directions with their respective sleeve shaft portions 7 as the axis, such as Figure 3 As shown in b, the two flip plates 6 rotate so that their respective planes intersect. That is, the two flip plates 6 open in opposite directions, thereby achieving a diversion effect on the passing wax liquid. In conjunction with the cylindrical inner wall of the vertical pipe section, the combined force causes the passing wax liquid to rotate around the axis of the vertical pipe section.

[0040] Specifically, such as Figure 3 、 Figure 5As shown, the vertical tube portion 3 is provided with a fixed shaft 14 along its diameter direction, and the two flip plates 6 are rotatably connected to the fixed shaft 14 through their respective sleeve shaft portions 7. The two sleeve shaft portions 7 are each provided with a driven bevel gear 15 at one end close to each other. The cross-rotation drive mechanism 8 includes a drive shaft 16, a drive bevel gear 17, and a servo motor 18. The swirl throttling structure 5 is provided at the upper end of the vertical tube portion 3 near the elbow of the discharge pipe 2. The drive shaft 16 is provided along the axis of the vertical tube portion 3. A shaft seat 19 is provided at the midpoint of the fixed shaft 14. One end of the drive shaft 16 is rotatably connected and placed in the shaft seat 19. The other end of the drive shaft 16 extends out of the outer wall of the elbow. A mounting platform 20 is provided on the outer wall of the elbow. The servo motor 18 is provided on the mounting platform 20. The servo motor 18 outputs The output end is connected to the driving shaft 16, and a driving bevel gear 17 is fixed to the lower end of the driving shaft 16. The two sides of the driving bevel gear 17 are respectively meshed and connected with the two driven bevel gears 15; in actual use, the servo motor 18 can accurately control the rotation angle of the driving shaft 16 and the driving bevel gear 17; the two sides of the driving bevel gear 17 are respectively meshed with the two driven bevel gears 15, which can form an effect of the driven bevel gears 15 on both sides rotating in opposite directions, thereby controlling the two flip plates 6 to rotate in opposite directions to open and maintain the opening.

[0041] The swirl throttling structure 5 has the function of limiting the outflow speed and flow rate of the wax liquid, so as to achieve the safe collection of high-temperature wax liquid. Secondly, it uses the internal flip plate 6 to guide the passing wax liquid, thereby applying a rotational torque to the wax liquid during the passing process, so that the wax liquid flows out with a certain rotational angular velocity. Since the wax liquid is driven by the flip plate 6 to rotate and flow out when flowing out, the outflow shape of the wax liquid is relatively concentrated, so there will be no dangerous situation where the wax liquid droplets flow in the discharge pipe 2 due to high-speed turbulence and splash laterally when flowing out of the pipe mouth.

[0042] Example 3:

[0043] The rotation angle of the flip plate 6 in the flip adjustment part is adjusted by the wax liquid level in the wax melting furnace. When the wax liquid level is high, the static pressure in the discharge pipe 2 is high and the wax liquid flow rate is fast. On the contrary, when the liquid level is low, the static pressure is low and the flow rate is slow. According to this principle, a liquid level signal acquisition mechanism is provided in the wax melting furnace body 1. The liquid level signal acquisition mechanism is connected to the input end of the controller 9. The output end of the controller 9 is connected to the cross rotation mechanism. When the wax liquid level is at a high level, the flip plate 6 in the flip adjustment part is controlled to be in a horizontal state, such as Figure 3 As shown in a; as the wax liquid is used, when the liquid level is about to reach the middle, the flip plates 6 on both sides can be controlled to open at a certain angle according to the liquid level signal, as shown in FIG. Figure 3 When the wax liquid level is low, the wax liquid static pressure is low and the flow rate tends to decrease, so at this time the control flip plate 6 is as shown in FIG. Figure 3As shown in the vertical state, the flip adjustment part greatly reduces the resistance to the wax liquid, which is the same as a cylindrical empty tube, making it easier for the wax liquid to flow out, thereby realizing the control of the liquid level height of the wax liquid; the liquid level signal acquisition mechanism can use an ultrasonic liquid level sensor to collect the liquid level data of the wax liquid and transmit it to the controller 9.

[0044] Furthermore, the liquid level signal acquisition structure can also be designed as the following structure, specifically, including a signal float and a signal receiver 13 coordinated with the signal float; the signal float includes a guide rod 10, a float 11, and a magnet 12, the guide rod 10 is vertically fixed on the side of the wax melting furnace body 1 close to the inner wall, the float 11 is sleeved and slidably connected on the guide rod 10, the magnet 12 is arranged on the outer side of the float 11, and the signal receiver 13 is vertically fitted on the side wall of the wax melting furnace body 1 to capture the magnetic field signal of the magnet 12 and convert it into liquid level data and send it to the controller 9. It can be understood that in actual use, the signal receiver 13 can adopt a Hall element, which can sense the height position of the magnet 12 by using the Hall effect Hall element, and convert it into an electrical signal and send it to the controller 9. The controller 9 controls the cross-rotation drive mechanism 8 according to the signal to control the rotation of the flip plates 6 on both sides according to the preset action mechanism.

[0045] Example 4:

[0046] The upper end of the vertical pipe portion 3 is connected to the horizontal pipe portion 21, and the other end of the horizontal pipe portion 21 is connected to the wax melting furnace body 1. Figure 4As shown, the length direction of the fixed flow hole 4 is perpendicular to the axial direction of the horizontal pipe part 21. It can be understood that when the wax liquid level in the wax melting furnace is at a high level, the static pressure at the bottom drain pipe 2 is relatively high. When the employee opens the discharge valve to take the wax liquid, the wax liquid rushes out from the horizontal pipe part 21 and passes through the guide of the elbow. Under the action of centrifugal force, the wax liquid must first adhere to the inner wall of the vertical pipe part 3 away from the wax melting furnace and flow downward. In this embodiment, as shown in the figure, the length direction of the fixed flow hole 4 is perpendicular to the axial direction of the horizontal pipe part 21. According to the above embodiment, when the wax liquid level in the wax melting furnace body 1 is high, the two flip plates 6 are controlled to be in a horizontal position. Therefore, the wax liquid rushing out at high speed will first collide with the flip plate 6 at the outer end after turning through the elbow, thereby deflecting the high-temperature wax liquid. After the deflection, the wax liquid rebounds or turns, which will backwash the subsequent wax liquid flowing out near the inside of the elbow, thereby forming a deceleration effect on the wax liquid in the entire vertical pipe part 3, and since the setting of the fixed flow hole 4 can form a stable downward flow rate, it can achieve better speed and flow limiting effects when the wax liquid is at a high liquid level; of course, on the contrary, the fixed flow hole 4 can also be set to be at an acute angle to the axis of the horizontal pipe part 21, or even parallel to it. Taking the extreme case as an example, when the fixed flow hole 4 is parallel to the axis of the horizontal pipe part 21, at a high liquid level, the wax liquid turns downward from the elbow, and a part of it can be directly sprayed downward through the fixed flow hole 4. Although the flow of the wax liquid passing through the fixed flow hole 4 is limited, the flow rate has not decreased at all. There is still a greater probability of safety risks after rushing out at high speed.

[0047] Embodiment 5:

[0048] The vertical pipe portion 3 is provided with a swirl guide belt 22 on the lower side of the swirl throttling structure 5. Figure 6 As shown, there are multiple swirl guide belts 22, which are spirally wound on the inner wall of the vertical tube portion 3 in a convex shape, and the multiple swirl guide belts 22 are centrally symmetrically arranged with the axis of the vertical tube portion 3; multiple swirl guide belts 22 can assist in driving the passing wax liquid, especially the wall-adhering layer of the wax liquid, to have a better driving rotation effect, and assist in promoting the rotation and outflow of the passing wax liquid.

[0049] Further, such as Figure 1 As shown, the horizontal pipe portion 21 is connected to one end of the wax melting furnace body 1 and a U-shaped continuous return portion 23 is provided inside the wax melting furnace body 1; the continuous return portion 23 can have a better buffering effect on the passing wax liquid when the liquid level is high.

[0050] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
