Description

Technical Field

[0001] This utility model relates to the technical field of sand filling devices, specifically to a square copper tube induction coil sand filling device. Background Technology

[0002] A copper tube induction coil is an electrothermal element made using the principle of induction heating. When a high-frequency alternating current is applied to the induction coil, it vibrates due to electromagnetic force. Therefore, sand (usually quartz sand) needs to be poured into the copper tube induction coil to increase its mass and fill internal gaps, effectively damping vibrations and reducing mechanical noise during operation. Simultaneously, the sand filling makes the stress inside the copper tube more uniform, reducing the risk of deformation or twisting caused by high-frequency current. Currently, the commonly used sand-pouring method is manual sand filling, which is inefficient and cannot guarantee the uniformity of sand filling inside the copper tube induction coil.

Detailed Implementation

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0017] A square copper tube induction coil sand-filling device, such as Figures 1 to 2 As shown, it includes a base 1, on which a sand storage tank mounting bracket 2 and a clamping mechanism for clamping the copper tube induction coil 15 are mounted. A sand storage tank 3 with its top facing downward is mounted at the center of the sand storage tank mounting bracket 2. A discharge pipe 4 is mounted on the top of the sand storage tank 3, and a switch valve 5 is mounted on the discharge pipe 4.

[0018] In this embodiment, the switch valve 5 is a manual switch valve, and the sand filling operation is performed by manually opening and closing the valve. In other embodiments, an electric valve can also be used to control the opening and closing of the discharge pipe.

[0019] The bottom of the sand storage tank 3 is equipped with a vent. When the sand storage tank is inverted on the sand storage tank mounting frame, the vent at the bottom of the sand storage tank can ensure the balance of pressure inside and outside the sand storage tank during sand filling, and prevent the sand storage tank from deforming due to pressure imbalance inside the sand storage tank after sand discharge.

[0020] The base 1 is equipped with a sand collection cylinder 14 to collect excess sand that overflows. The sand collection cylinder 14 is located below the clamping mechanism and is coaxially arranged with the sand storage tank mounting frame 2.

[0021] The clamping mechanism includes two clamping blocks 6 arranged opposite each other. The opposite sides of the clamping blocks 6 are provided with slots 7 for clamping the square copper tube induction coil 15. In this embodiment, the slots 7 are in the shape of isosceles right triangles, and the two slots 7 are spliced ​​together to form a square structure.

[0022] Anti-slip pads are provided around the seven sides of the bayonet, which can increase the friction between the bayonet and the square copper tube induction coil, ensuring the stability between the bayonet and the square copper tube induction coil.

[0023] The other end of the clamping block 6 is connected to the hinge seat 8. The hinge seat 8 is set perpendicular to the line connecting the two clamping blocks 6. The two ends of the hinge seat 8 are respectively hinged to the connecting rod 9. The other end of the connecting rod 9 is hinged to the moving plate 10. The moving plate 10 is threadedly connected to the lead screw 11. The lead screw 11 is connected to the motor 13. The motor 13 drives the lead screw 11 to rotate. The two moving plates 10 move in opposite directions along the axis of the lead screw. The clamping and releasing of the clamping block 6 is realized through the cooperation of the moving plate 10 and the connecting rod 9.

[0024] The lead screw 11 is mounted on the lead screw mounting bracket 12, which is located on the outside of the sand storage tank mounting bracket 2. A motor bracket for mounting the motor 13 is provided on one side of the lead screw mounting bracket 12.

[0025] When in use, first place the sand storage tank 3 with the top facing down onto the sand storage tank mounting bracket 2, and then control the motor to separate the two clamping blocks 6.

[0026] Then, place the square copper tube induction coil 15 between the two clamping blocks and align it with the bayonet 7. After that, start the motor and control the motor to reverse so that the two clamping blocks 6 clamp the square copper tube induction coil 15.

[0027] Next, open the switch valve 5 to allow the sand in the sand storage tank 3 to fall from the discharge pipe 4 into the square copper tube induction coil 15. After the sand filling is completed, control the two clamping blocks to move away from each other and remove the square copper tube induction coil.

[0028] Once the sand in the sand collection cylinder has accumulated to a certain amount, the sand collection cylinder is removed and replaced with a new one. After processing, the collected sand can be reused.

[0029] This utility model provides a sand-filling device for a square copper tube induction coil. Through the cooperation of a sand storage tank mounting frame, a sand storage tank, and a clamping mechanism, it achieves uniform sand filling of the square copper tube induction coil, solving the problem of low efficiency of manual sand filling, improving sand filling efficiency, ensuring the uniformity of sand filling, and collecting excess sand at the bottom by setting a sand collection cylinder to facilitate the use of sand and save costs.
