Description

Technical Field

[0001] This utility model relates to the field of glass production technology, and in particular to a device for recycling precious metal pipes. Background Technology

[0002] Precious metal tubing possesses high melting points and high-temperature strength, along with excellent processing properties. For example, platinum tubing is commonly used in glass melting and casting. To improve resource utilization, precious metal tubing used in glass production needs to be recycled after reaching its service life. Some cooled solid glass inevitably remains on the sidewalls of the used precious metal tubing; this residue must be removed before recycling can be achieved.

[0003] Currently, the common method for removing solid glass residue on the sidewalls of precious metal pipes is to apply hydraulic pressure and vibration to the precious metal pipes, causing the solid glass attached to the sidewalls to break under external force, thereby achieving separation. However, this method is inefficient and can cause some damage to the precious metal pipes. Furthermore, for precious metal pipes with an inner diameter of less than 3mm, the glass removal effect is poor, which is not conducive to the recycling of precious metal pipes. Utility Model Content

[0004] The technical problem solved by this utility model is to provide a recycling device for precious metal pipes with high recycling efficiency and good effect, which is suitable for precious metal pipes with an inner diameter of less than 3mm.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a precious metal pipe recycling device, including a heating component and a pipe vertical positioning component. The heating component includes a heating box, and the pipe vertical positioning component includes a hollow vertical positioning tube. At least one positioning structure is provided in the vertical positioning tube. A precious metal pipe can be vertically positioned in a positioning structure, and the pipe vertical positioning component can be vertically placed in the heating box.

[0006] Furthermore, the vertical positioning tube includes a hollow tube body and a tube cap, with the tube cap being detachably mounted on the tube body.

[0007] Furthermore, the bottom of the tube body is provided with at least one first vertical positioning through hole, the shape of which is a frustum-shaped cone with a larger top and a smaller bottom, and the tube cover is provided with at least one second vertical positioning through hole, the vertical center line of the second vertical positioning through hole and the vertical center line of the first vertical positioning through hole are on the same vertical straight line.

[0008] A positioning structure includes a second vertical positioning through hole and a first vertical positioning through hole corresponding to the upper and lower positions.

[0009] Furthermore, the distance between a second vertical positioning through hole and a first vertical positioning through hole corresponding to the upper and lower positions is less than the length of a precious metal pipe.

[0010] Furthermore, the first vertical positioning through hole is a glass liquid outlet through hole, and also includes a glass liquid receiving tank, in which a glass liquid receiving trough is provided, and the glass liquid receiving trough is located below the first vertical positioning through hole.

[0011] Furthermore, a pipe placement slot is provided in the glass liquid receiving tank, which is connected to the glass liquid receiving tank and is located directly above the glass liquid receiving tank. The cross-sectional diameter of the pipe placement slot is larger than that of the glass liquid receiving tank.

[0012] The vertical positioning tube is matched and set in the tube placement groove.

[0013] Furthermore, it also includes a cabinet, with the heating box located inside the cabinet and situated in the upper middle part of the cabinet;

[0014] The bottom of the heating chamber is equipped with a feed inlet, and the cabinet is equipped with a lifting component. The lifting component is connected to the glass liquid receiving tank through a connecting plate. The lifting component can move the glass liquid receiving tank up and down, thereby driving the glass liquid receiving tank into or out of the heating chamber through the feed inlet.

[0015] Furthermore, the lifting assembly includes a geared motor and a lead screw, which is vertically installed in the cabinet. The output shaft of the geared motor is connected to the lead screw, and a connecting plate is threaded onto the lead screw.

[0019] The beneficial effects of this utility model are as follows: When recycling precious metal pipes, the precious metal pipes are first installed vertically in the vertical positioning tube of the vertical positioning component of the pipe through a positioning structure. Then, the vertical positioning component of the pipe and the precious metal pipes are placed in a heating box. In the heating box, the precious metal pipes are in a vertical state. Finally, the heating box is used to heat the pipes, melting the solid glass on the side wall into liquid glass. The liquid glass flows out along the side wall of the precious metal pipes under its own weight, thereby removing the solid glass from the side wall and realizing the recycling of the precious metal pipes.

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] The directions mentioned below are in the form of Figure 1 The orientation of each component is used as a reference.

[0031] like Figures 1 to 8 As shown, the precious metal pipe recycling device of this utility model includes a heating component and a pipe vertical positioning component. The heating component includes a heating box 1, and the pipe vertical positioning component includes a hollow vertical positioning tube 2. At least one positioning structure is provided in the vertical positioning tube 2. A precious metal pipe 3 can be vertically positioned in a positioning structure, and the pipe vertical positioning component can be vertically placed in the heating box 1.

[0032] When recycling precious metal pipes, the precious metal pipe 3 is first installed vertically in the vertical positioning pipe 2 of the vertical positioning assembly using a positioning structure, such as... Figure 1 , Figure 2 As shown, the vertical positioning assembly and the precious metal pipe 3 are then placed into the heating chamber 1. Inside the heating chamber 1, the precious metal pipe 3 is in a vertical position, as shown... Figure 3 As shown, finally, by operating the heating box 1, the precious metal tube 3 is heated to 1400°C, and the solid glass on the side wall of the precious metal tube 3 is melted into liquid glass. The liquid glass flows out along the side wall of the precious metal tube 3 under its own weight, thereby removing the solid glass on the side wall of the precious metal tube 3 and realizing the recycling of the precious metal tube 3.

[0033] Specifically, to facilitate the use and maintenance of the vertical positioning tube 2, for example... Figures 4 to 7 As shown, the vertical positioning tube 2 includes a hollow tube body 21 and a tube cap 22, with the tube cap 22 detachably mounted on the tube body 21. When maintaining the tube body 21, the tube cap 22 is removed from the tube body 21.

[0034] The function of the positioning structure is to vertically install the precious metal pipe 3 in the vertical positioning tube 2 of the pipe vertical positioning assembly. A preferred embodiment of the positioning structure of this utility model is as follows: (Example...) Figures 4 to 7 As shown, the bottom of the tube body 21 is provided with at least one first vertical positioning through hole 211, which is shaped like a frustum, wider at the top and narrower at the bottom. The tube cover 22 is provided with at least one second vertical positioning through hole 221, and the vertical center line of the second vertical positioning through hole 221 and the vertical center line of the first vertical positioning through hole 211 are on the same vertical straight line. A positioning structure includes a second vertical positioning through hole 221 and a first vertical positioning through hole 211 that are correspondingly positioned vertically. The corresponding vertical positions refer to the second vertical positioning through hole 221 and the first vertical positioning through hole 211 whose vertical center lines are on the same vertical straight line. The second vertical positioning through hole 221 is cylindrical, and its cross-sectional diameter is 1 mm larger than the cross-sectional diameter of the precious metal tube 3. The maximum cross-sectional diameter of the first vertical positioning through hole 211 is also 1 mm larger than the cross-sectional diameter of the precious metal tube 3. When recycling the precious metal tube 3, one precious metal tube 3 is installed in a second vertical positioning through hole 221 and a first vertical positioning through hole 211. The first vertical positioning through hole 211 is shaped like a frustum, which is larger at the top and smaller at the bottom, ensuring that the first vertical positioning through hole 211 can position and fix the precious metal tube 3, and also facilitating the outflow of liquid glass.

[0035] To facilitate the installation and disassembly of the precious metal pipe 3, for example... Figure 4As shown, the distance between a second vertical positioning through hole 221 and a first vertical positioning through hole 211 corresponding to the upper and lower positions is less than the length of a precious metal tube 3. That is, the length of the precious metal tube 3 is greater than the distance between a second vertical positioning through hole 221 and a first vertical positioning through hole 211 corresponding to the upper and lower positions. The precious metal tube 3 protrudes to the upper part of the second vertical positioning through hole 221. The protruding part of the precious metal tube 3 can be used as a handle to facilitate the installation and disassembly of the precious metal tube 3 by the staff.

[0036] To facilitate the collection of molten glass, for example... Figure 4 As shown, the first vertical positioning through-hole 211 is a glass melt outlet through-hole, and also includes a glass melt receiving tank 4, in which a glass melt receiving trough 42 is provided, positioned directly below the first vertical positioning through-hole 211. Liquid glass melt flows into the first vertical positioning through-hole 211 through the side wall of the precious metal pipe 3, and then flows along the first vertical positioning through-hole 211 into the glass melt receiving trough 42 for collection.

[0037] To improve the stability of the vertical positioning components for pipes, for example... Figure 4 , Figure 8 As shown, a tube placement groove 41 is provided in the glass liquid receiving tank 4. The tube placement groove 41 is connected to the glass liquid receiving tank 42, and the tube placement groove 41 is located directly above the glass liquid receiving tank 42. The cross-sectional diameter of the tube placement groove 41 is larger than the cross-sectional diameter of the glass liquid receiving tank 42. The vertical positioning tube 2 is matched and installed in the tube placement groove 41.

[0038] To make the recycling equipment easier to use and improve its safety, for example... Figure 1 , Figure 2 As shown, this utility model also includes a cabinet 5, and a heating box 1 is installed in the cabinet 5 and located in the upper middle part of the cabinet 5.

[0039] A feed inlet is located at the bottom of the heating chamber 1, and a lifting assembly 6 is installed in the cabinet 5. The lifting assembly 6 is connected to the glass melt receiving tank 4 via a connecting plate 61. The lifting assembly 6 can move the glass melt receiving tank 4 up and down, thereby driving the glass melt receiving tank 4 into or out of the heating chamber 1 through the feed inlet. Since the vertical positioning tube 2 is installed on the glass melt receiving tank 4, and the precious metal tube 3 is installed in the vertical positioning tube 2, the lifting assembly 6 moves the glass melt receiving tank 4 up and down, thereby moving the vertical positioning tube 2 and the precious metal tube 3 up and down, so that the precious metal tube 3 can enter or exit the heating chamber 1 through the feed inlet, avoiding direct contact between personnel and the high temperature of the heating chamber 1, and improving safety.

[0040] The function of the lifting assembly 6 is to move the glass melt receiving tank 4 up and down, thereby enabling the precious metal pipe 3 to move up and down. To improve the stability of the lifting assembly 6, a preferred structure of this utility model is as follows: the lifting assembly 6 includes a geared motor and a lead screw. The lead screw is vertically arranged in the cabinet 5. The output shaft of the geared motor is connected to the lead screw, and a connecting plate 61 is threaded onto the lead screw. The working principle of this lifting assembly 6 is as follows: the geared motor rotates its output shaft, which in turn drives the lead screw to rotate. The rotation of the lead screw, under the action of the thread, causes the connecting plate 61 to move up and down, thus moving the glass melt receiving tank 4 up and down. To improve automation and ease of use, the geared motor is a servo motor, and a control panel is provided on the surface of the cabinet 5. The control panel has a controller, which is electrically connected to the geared motor.

[0041] To facilitate the connection between the connecting plate 61 and the glass liquid receiving tank 4, a base is provided between the connecting plate 61 and the glass liquid receiving tank 4.

[0042] To improve the heating and heat preservation effects of heating box 1, for example... Figure 3 As shown, this utility model also includes an insulation board 8, which is detachably mounted at the feed inlet via an insulation board fixing mechanism 9.

[0043] To facilitate maintenance of heating chamber 1, a removable front cover is provided on the front side of heating chamber 1.

[0044] To improve the stability of the entire recycling device, a fixed support base 7 is connected to the bottom of the cabinet 5.

[0045] In summary, compared with existing recycling methods, this method does not damage the precious metal pipe 3, improves recycling efficiency and effectiveness, and is also suitable for precious metal pipes 3 with an inner diameter of less than 3mm, which is conducive to large-scale use.
