Abstract
Description
Technical Field
[0001] This utility model relates to the field of heating rod processing technology, specifically to a magnesium oxide filling device that is easy to maintain. Background Technology
[0002] The magnesium oxide filling inside the heating element is a common insulating and thermally conductive material. Its high insulation, high temperature resistance (melting point up to 2800℃), and good thermal conductivity effectively isolate the heating wire from the metal casing, preventing leakage while rapidly transferring heat. After being compacted under high pressure, the magnesium oxide powder also enhances the mechanical strength of the heating element, making it adaptable to high-temperature expansion and vibration environments. It is widely used in electric water heaters, ovens, and other appliances to ensure safe and stable heating performance.
[0003] In current applications, magnesium oxide particles are typically filled into heating tubes using a filling machine. However, during this process, some magnesium oxide particles inevitably leak from the upper end of the heating tube. These leaked particles often accumulate in the gaps between the mechanical parts of the filling machine, leading to wear and tear. This wear necessitates frequent maintenance, increasing costs and impacting production efficiency. Therefore, to reduce magnesium oxide particle leakage and the resulting wear, existing filling machines need improvement, or new filling technologies need to be developed to enhance filling efficiency and equipment durability. To this end, a magnesium oxide filling device with easy maintenance is proposed. Utility Model Content
[0004] The purpose of this invention is to provide a magnesium oxide filling device that is easy to maintain, so as to solve the problems in the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a magnesium oxide filling device that is easy to maintain, comprising a device base, a support bracket fixedly installed on the device base, a limit groove provided on the support bracket, a magnesium oxide storage tank fixedly installed on the top of the support bracket, a lifting mechanism provided on the outside of the support bracket, the lifting mechanism comprising a drive screw rotatably installed on the outside of the support bracket, a screw nut threaded on the drive screw, an ear seat fixedly installed on the screw nut, a spring provided on the ear seat, and a filling mechanism connected to the spring.
[0006] Preferably, a worm gear is fixedly installed at the lower end of the drive screw, a worm is rotatably installed on one side of the worm gear, a linkage shaft is fixedly installed on the worm, and a handwheel is fixedly installed on the linkage shaft.
[0007] Preferably, the equipment base is provided with a retainer, and the linkage shaft is rotatably mounted in the equipment base through the retainer.
[0008] Preferably, the worm is rotatably mounted on one side of the worm wheel via a linkage shaft, and the worm wheel and worm are meshed together. The lug on the lead screw nut is slidably mounted on the support bracket via a limiting groove. The equipment base is provided with a bearing, and the drive lead screw is rotatably mounted on the equipment base via the bearing.
[0009] Preferably, the filling mechanism includes a filling funnel fixedly installed at the bottom of the equipment base and a receiving groove connected to the upper end of the spring. A silicone plate is fixedly installed on the filling funnel. A bolt is provided on one side of the receiving groove. A bayonet is provided on the receiving groove. A sealing ring is provided in the bayonet. A heating tube is connected in the bayonet. A recycling tank is provided at both ends of the receiving groove. A vibration motor is fixedly installed at the bottom of the receiving groove. An installation port is provided at the bottom of the magnesium oxide storage tank. The filling funnel is installed at the bottom of the magnesium oxide storage tank through the installation port. A gate is provided at the bottom of the magnesium oxide storage tank.
[0010] Preferably, the bottom of the receiving trough is provided with a threaded opening, and the recycling tank is connected to the bottom of the receiving trough through the threaded opening.
[0011] Preferably, one end of the spring is fixed to the lug of the lead screw nut, and the other end of the spring is fixed in the receiving groove.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. In this application, the linkage shaft rotates under the drive of the handwheel, which in turn drives the worm gear to rotate. The rotation of the worm gear drives the worm wheel to rotate, which in turn drives the lead screw to rotate. The rotation of the lead screw causes the lead screw nut to move axially, thereby pushing the receiving groove upward. This movement causes the receiving groove to contact the bottom of the silicone plate, forming a closed filling environment, effectively preventing magnesium oxide particles from penetrating into the gaps of the mechanical parts.
[0014] 2. In this application, the filling funnel can be inserted into the heating tube. Subsequently, the gate at the bottom of the magnesium oxide storage tank can be opened to allow magnesium oxide particles to fill the heating tube. During the filling process, the activation of the vibration motor will promote the vibration of the heating tube, thereby ensuring the magnesium oxide particles inside the tube are tightly packed. Because the receiving trough is designed with a high center and low sides, during vibration, magnesium oxide particles scattered in the receiving trough will be vibrated into the recovery tank, thus achieving the recycling of the magnesium oxide particles.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a magnesium oxide filling device that is easy to maintain. It includes a device base 1, a support bracket 3 fixedly installed on the device base 1, a limit groove 4 opened on the support bracket 3, a magnesium oxide storage tank 5 fixedly installed on the top of the support bracket 3, a lifting mechanism 6 provided on the outside of the support bracket 3, and a filling mechanism 7 connected to a spring 608. The cooperation of the lifting mechanism 6 and the filling mechanism 7 can prevent magnesium oxide particles from falling into the gaps between mechanical parts and can recover the scattered magnesium oxide particles.
[0022] like Figure 2 and Figure 3 As shown, the lifting mechanism 6 includes a drive screw 601 rotatably mounted on the outside of the support bracket 3. A screw nut 602 is threaded onto the drive screw 601. An ear seat 603 is fixedly mounted on the screw nut 602. A spring 608 is provided on the ear seat 603. A worm gear 604 is fixedly mounted on the lower end of the drive screw 601. A worm 606 is rotatably mounted on one side of the worm gear 604. A linkage shaft 607 is fixedly mounted on the worm 606. A handwheel 605 is fixedly mounted on the linkage shaft 607. A retainer is provided inside the equipment base 1. The linkage shaft 607 is rotatably mounted inside the equipment base 1 through the retainer.
[0023] Specifically, the rotation of handwheel 605 is transmitted to linkage shaft 607, causing linkage shaft 607 to rotate. The rotation of linkage shaft 607 is further transmitted to worm gear 606, causing worm gear 606 to also rotate. The rotation of worm gear 606 drives the meshing worm wheel 604 to rotate. The rotation of worm wheel 604 continues to transmit, causing drive screw 601 to rotate. The rotation of drive screw 601 ultimately causes screw nut 602 to move upward, which in turn causes receiving groove 703 to move upward. After receiving groove 703 moves upward to a certain position, it contacts the bottom of silicone plate 702, thus forming a closed filling environment. In this closed environment, the upper end of heating tube 2 is completely surrounded, effectively preventing magnesium oxide particles from scattering and thus avoiding potential damage to mechanical parts caused by magnesium oxide particles.
[0024] like Figure 2 and Figure 4 As shown, the filling mechanism 7 includes a filling funnel 701 fixedly installed at the bottom of the equipment base 1 and a receiving groove 703 connected to the upper end of the spring 608. A silicone plate 702 is fixedly installed on the filling funnel 701. A bolt 706 is provided on one side of the receiving groove 703. A bayonet 707 is provided on the receiving groove 703. A sealing ring 708 is provided inside the bayonet 707. A heating tube 2 is connected inside the bayonet 707. A recovery tank 704 is provided at both ends of the receiving groove 703. A vibration motor 705 is fixedly installed at the bottom of the receiving groove 703. An installation port is provided at the bottom of the magnesium oxide storage tank 5. The filling funnel 701 is installed at the bottom of the magnesium oxide storage tank 5 through the installation port. A gate is provided at the bottom of the magnesium oxide storage tank 5. A threaded port is provided at the bottom of the receiving groove 703. The recovery tank 704 is connected to the bottom of the receiving groove 703 through the threaded port.
[0025] Specifically, after the receiving trough 703 contacts the bottom of the silicone plate 702, the filling funnel 701 is guided into the heating tube 2. Once the filling funnel 701 successfully extends into the heating tube 2, the next step is to open the gate at the bottom of the magnesium oxide storage tank 5, allowing the magnesium oxide particles to smoothly fill the heating tube 2. During the filling process, the vibration motor 705 can be activated. Once activated, the vibration motor 705 will cause the heating tube 2 on the receiving trough 703 to vibrate. This vibration helps to make the magnesium oxide particles in the heating tube 2 more compact. In addition, the receiving trough 703 is designed to be higher in the middle and lower on both sides. This design allows the magnesium oxide particles that fall into the receiving trough 703 during vibration to be shaken into the recycling tank 704. In this way, the scattered magnesium oxide particles can be effectively recycled.
[0026] Working principle: In use, first connect the upper end of the heating tube 2 into the bayonet 707, then tighten the bolt 706 to fix the upper end of the heating tube 2 into the bayonet 707. After the upper end of the heating tube 2 is fixedly installed in the bayonet 707, the handwheel 605 can be turned. Turning the handwheel 605 will drive the linkage shaft 607 to rotate. After the linkage shaft 607 rotates, it will drive the worm gear 606 to rotate. After the worm gear 606 rotates, it will drive the worm wheel 604 to rotate. After the worm wheel 604 rotates, it will drive the drive screw 601 to rotate. After the drive screw 601 rotates, it will drive the screw nut 602 to move upward. After the screw nut 602 moves upward, it will drive the receiving groove 703 to move upward and abut against the bottom of the silicone plate 702, so that the upper end of the heating tube 2 is in a closed filling environment, preventing magnesium oxide particles from falling into the gaps between mechanical parts. After the receiving trough 703 comes into contact with the bottom of the silicone plate 702, the filling funnel 701 will extend into the heating tube 2. After the filling funnel 701 extends into the heating tube 2, the gate at the bottom of the magnesium oxide storage tank 5 can be opened, allowing magnesium oxide particles to fill into the heating tube 2. During the filling process, the vibration motor 705 can be started. After the vibration motor 705 is started, it will drive the heating tube 2 on the receiving trough 703 to vibrate, making the magnesium oxide particles in the heating tube 2 compact. The receiving trough 703 is higher in the middle and lower on both sides. During the vibration of the receiving trough 703, the magnesium oxide particles scattered in the receiving trough 703 will be shaken into the recovery tank 704, realizing the recovery of scattered magnesium oxide particles.
