[0039] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0040] like Figure 1-5 As shown, this utility model discloses a recycling and separation device for used fiberglass cooling sheets, comprising a housing 1, a pot 2, a heating element 3, a screening mechanism 4, and a collection element 5. The housing 1 has a window 100 on one side; the pot 2 is located inside the housing 1, with one end extending outward through the window 100; the heating element 3 is located inside the housing 1 and is used to heat the pot 2 to separate the cooling sheets from the copper base; the screening mechanism 4 is located inside the pot 2 and is spaced apart from the inner wall of the pot 2, and is used to vibrate and screen the cooling sheets; the collection element 5 is detachable on the side of the housing 1 away from the window 100 and is positioned corresponding to the pot 2, and is used to collect the screened cooling sheets.

[0041] It should be noted that the cooling plate and the copper base are usually connected together by brazing. The heating element 3 is set inside the box 1 to heat the pot 2. When the temperature inside the pot 2 rises to a certain level, the brazing material begins to melt, causing the connection between the cooling plate and the copper base to gradually weaken. Through continuous heating, the cooling plate and the copper base eventually separate. The screening mechanism 4 screens the separated cooling plate and copper base by vibration. The screened cooling plate falls into the collection device 5 for collection. The collection device 5 is detachably connected to the box 1 for regular cleaning of the internal cooling plate. The combination of the heating element 3, screening mechanism 4 and collection device 5 can heat, separate and vibrate the cooling plate and copper base, and collect the cooling plate, achieving efficient separation and recycling of the cooling plate and copper base, improving resource recycling and reducing production costs.

[0042] In a preferred embodiment, the box 1 in this embodiment includes a shell 11, a cover plate 12, and a partition plate 13. The shell 11 is hollow inside and has an opening 110 on one side. The cover plate 12 is fixed to the opening side of the shell 11 by bolts. The window 100 is opened on the cover plate 12 and is located at the center. The partition plate 13 is disposed inside the shell 11 and has a placement hole 130 on the partition plate 13 that is coaxial with the window 100. The pot body 2 abuts between the placement hole 130 and the window 100, and the position of the pot body 2 is fixed by the cover plate 12.

[0043] It should be noted that the outer contour of the pot body 2 is divided into two gradient lines. The diameter of the first section gradually increases from the top port of the pot body 2 to the dividing line, and the diameter of the second section gradually decreases from the dividing line to the bottom port of the pot body 2. The pot body 2 is inserted into the placement hole 130, and its outer wall abuts against the inner wall of the placement hole 130. Furthermore, the diameter of the window 100 is smaller than the diameter at the dividing line, so that when the cover plate 12 is threaded to the shell 11, the first section of the pot body 2 extends through to the outside of the window 100, and the cover plate 12 abuts against the outer wall of the first section of the pot body 2, thereby completing the fixation of the position of the pot body 2.

[0044] In a preferred embodiment, the heating element 3 is a heating coil, which is wound around the outside of the pot body 2 for heating the pot body 2.

[0045] It should be noted that the heating coil, as a resistance wire, generates heat directly due to its resistance when current is applied. This heat is transferred to the pot body 2 through thermal conduction, causing its temperature to rise. The heating coil is wound around the outside of the pot body 2, which ensures that the pot body 2 is heated evenly and avoids local overheating or undercooling. It also helps the brazing filler between the cooling plate and the copper base to melt evenly, improving separation efficiency.

[0046] This embodiment also includes a control box 6, which is located on one side of the box body 1 and contains a heating drive circuit for controlling the heating element 3.

[0047] In a preferred embodiment, the heating drive circuit includes a positive power supply terminal, a negative power supply terminal, resistors R1 and R2, Zener diodes D1 and D2, thyristors T1 and T2, capacitor C1, coil L1, and coil L2. The positive power supply terminal is electrically connected to one end of coil L2, and the other end of coil L2 is electrically connected to coil L1. One end of coil L1 is electrically connected to capacitor C1, the drain of thyristor T1, and the positive terminal of Zener diode D2. The other end of coil L1 is electrically connected to the other end of capacitor C1, the drain of thyristor T2, and the positive terminal of Zener diode D1. The base of thyristor T1 is electrically connected to the negative terminal of Zener diode D1 and resistor R1. The base of thyristor T2 is electrically connected to the negative terminal of Zener diode D2 and resistor R2. The sources of thyristors T1 and T2 are grounded. The other ends of resistors R1 and R2 are connected to the common negative power supply terminal.

[0048] It should be noted that when thyristor T1 is on and thyristor T2 is off, the current flows from the positive terminal of the power supply through thyristor T1, coils L1 and L2, and Zener diode D2 back to the negative terminal of the power supply, forming a positive current loop. At this time, coils L1 and L2 are heated. The connection contacts of coils L1 and L2 can slide, thereby adjusting the resistance of the circuit and regulating the heating temperature. Zener diodes D1 and D2 act as freewheeling diodes. When thyristor T1 or T2 is suddenly turned off, the current in the load can continue to flow through Zener diodes D1 or D2, preventing high voltage spikes from damaging the switching elements. Resistors R1 and R2 are current-limiting resistors used to limit the current flowing into the gates of thyristors T1 and T2. By controlling the gate voltages of thyristors T1 and T2, precise control of the heating process can be achieved.

[0049] This embodiment also includes a surrounding panel 7 and an insulation layer 8. The surrounding panel 7 is disposed inside the housing 1 and is located between the shell 11 and the heating element 3. The insulation layer 8 is disposed in the gap between the surrounding panel 7 and the shell 11 and is used to keep the heat insulated.

[0050] It should be noted that by setting up the enclosure 7 and the insulation layer 8, heat loss and transfer can be reduced, allowing more heat to concentrate around the heating element 3, thereby improving heating efficiency. At the same time, the isolation effect of the enclosure 7 can prevent the heating element 3 from directly heating the shell 11, avoiding overheating of the shell 11 and causing safety hazards.

[0051] Specifically, in this embodiment, the insulation layer 8 is insulation asbestos.

[0052] The screening mechanism 4 in this embodiment includes a grid plate 41, a piston rod 42, a drive member 43, a cam 44, and a spring assembly 45. The grid plate 41 is located inside the pot body 2 and is spaced apart from the inner wall of the pot body 2. One end of the piston rod 42 passes through the control box 6 and the surrounding plate 7 in sequence and extends into the pot body 2 and is fixedly connected to the grid plate 41. The other end of the piston rod 42 is fixedly connected to the spring assembly 45. The drive member 43 is located inside the control box 6. The cam 44 is fixed on the output shaft of the drive member 43, and the outer side of the cam 44 abuts against the other end of the spring assembly 45 to drive the grid plate 41 to reciprocate linearly.

[0053] It should be noted that the mesh plate 41 is provided with sieve holes to separate the cooling fins from the copper base. When the drive component 43 drives the cam 44 to rotate, it will periodically compress the spring assembly 45. When the spring assembly 45 is compressed by the cam 44, it will undergo elastic deformation and store energy. When the compression force of the cam 44 decreases, the spring assembly 45 will release energy and push the piston rod 42 and the mesh plate 41 to move in opposite directions. Thus, through the continuous rotation of the cam 44 and the elastic action of the spring assembly 45, the piston rod 42 and the mesh plate 41 will achieve reciprocating linear motion, causing the cooling fins on the mesh plate 41 to vibrate, thereby achieving screening and improving screening efficiency.

[0054] The spring assembly 45 in this embodiment includes a sleeve 451, an elastic element 452, and a telescopic element 453. The other end of the piston rod 42 is fixedly connected to the end face of the sleeve 451. The elastic element 452 is disposed inside the sleeve 451. The telescopic element 453 is slidably connected inside the sleeve 451, with one end extending outward through the sleeve 451 and abutting against the outer wall of the cam 44, and the other end abutting against the elastic element 452.

[0055] In this embodiment, the spring assembly 45 achieves elastic support and reciprocating motion drive for the piston rod 42 through the coordinated action of the sleeve 451, the elastic element 452, and the telescopic element 453.

[0056] In this embodiment, the partition 13 divides the interior of the shell 11 into an upper cavity and a lower cavity. The pot body 2 is located in the upper cavity. The shell 11 has a sliding opening 150 connected to the lower cavity on the side away from the control box 6. The collecting component 5 is slidably connected in the sliding opening 150, and the end face of the collecting component 5 abuts against the partition 13.

[0057] It should be noted that the heating element 3 heats the pot body 2, causing the brazing material between the cooling plate and the copper base to melt. The melted brazing material and any fragments of the cooling plate that may fall off will fall into the lower cavity. Once a certain amount of material has accumulated in the lower cavity, the operator can push the collecting element 5 to slide it outward along the sliding opening 150, which can clean or further process the material in the collecting element 5.

[0058] Working principle:

[0059] Pour the old fiberglass cooling sheet into the furnace body 2, start the heating drive circuit in the control box 6 to make the heating element 3 start working and heat the pot body 2. When the temperature inside the pot body 2 rises to a certain level, the brazing material begins to melt, which gradually weakens the connection between the cooling sheet and the copper base. Through continuous heating, the cooling sheet and the copper base eventually separate, and the mixture of the separated cooling sheet and the copper base falls onto the grid plate 41.

[0060] The drive unit 43 is activated, causing the cam 44 to rotate and periodically compress the spring assembly 45, causing the piston rod 42 and the grid plate 41 to reciprocate linearly. This causes the mixture of cooling plates and copper base to vibrate and be separated from the copper base through the sieve holes on the grid plate 41. The cooling plates fall into the lower cavity through the sieve holes. After a certain amount of cooling plates have accumulated in the lower cavity, the operator can push the collection unit 5 to slide it outward along the slide 150 to clean the cooling plates in the collection unit 5 and remove impurities and residues.

[0061] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
