Description

Technical Field

[0001] The utility model relates to the technical field of sintering furnaces, in particular to a rapid cooling sintering furnace. Background Art

[0002] Sintering furnace refers to a special equipment that makes the powder compact obtain the required physical, mechanical properties and microstructure through sintering. Sintering furnace is mainly used to dry the slurry on the silicon wafer, remove the organic components in the slurry, and complete the sintering of aluminum back field and gate line.

[0003] A fast cooling sintering furnace is disclosed in the Chinese utility model patent with the announcement number CN217275622U. The device divides the water in the water storage tank through the condenser assembly, so that the outer shell can be cooled in two directions, thereby improving the cooling efficiency and cooling effect. The rotation of the water impeller can drive the water inside the water storage tank to mix, thereby accelerating the cooling of the water body. With respect to the above-mentioned related technologies, the inventor believes that there are the following defects:

[0004] When the device is actually used, the water in the water tank is constantly circulated and transported, and the rotation of the hydraulic blades drives the water to mix and achieve cooling, which is a time-consuming process. In addition, the temperature generated by the sintering furnace is relatively high, which makes the water temperature inside the condenser tube relatively high. As a result, the water in the water tank is prone to being recycled without being able to lower its temperature in time, thereby reducing the cooling effect of the sintering furnace. For this reason, we provide a fast cooling sintering furnace. Utility Model Content

[0005] In order to solve the problem in the above background technology that the water in the water storage tank is easily unable to reduce the temperature in time and is recycled, which reduces the cooling effect of the sintering furnace, the utility model provides a fast cooling sintering furnace.

[0006] The utility model adopts the following technical scheme to achieve: a rapid cooling sintering furnace, comprising:

[0007] A sintering furnace body, wherein the outside of the sintering furnace body is respectively fixedly sleeved with a spiral cooling pipe 1 and a spiral cooling pipe 2, a water tank is arranged below the sintering furnace body, two groups of submersible pumps are fixedly installed inside the water tank, the water inlet ends of the spiral cooling pipe 1 and the spiral cooling pipe 2 are both fixedly connected with a water inlet pipe, and the two groups of water inlet pipes are respectively connected with the water outlets of the two groups of submersible pumps, and the water outlet ends of the spiral cooling pipe 1 and the spiral cooling pipe 2 are both fixedly connected with a water outlet pipe, and the two groups of water outlet pipes are both connected with the water tank;

[0008] A dust removal and cooling assembly, the dust removal and cooling assembly includes two sets of vertical plates which are sleeved on the outside of the horizontal section of a water outlet pipe, an annular sponge is fixedly connected to the vertical plates, the tops of the two sets of vertical plates are fixedly connected to the same liquid storage tank, the top center of the liquid storage tank is fixedly connected to a liquid injection pipe, one side of the liquid storage tank is symmetrically fixedly connected to a cross bar which is slidably connected to the water tank, a connecting plate is provided inside the water tank and the connecting plate is fixedly connected to the two sets of cross bars at the same time, and a return spring is sleeved on the outside of the cross bar.

[0009] As a further improvement of the above scheme, a stepper motor is fixedly connected to one side of the water tank, a rotating shaft is rotatably connected inside the water tank and one end of the rotating shaft is coaxially fixedly connected to the rotor end of the stepper motor, and a toggle plate is fixedly connected to the outside of the rotating shaft.

[0010] As a further improvement of the above solution, the vertical plate is a hollow structure and is connected to the liquid storage tank.

[0011] As a further improvement of the above solution, leakage holes are evenly arranged at the bottom of the inner cavity of the vertical plate.

[0012] As a further improvement of the above solution, a guide block is fixedly connected to the bottom of the inner cavity of the liquid storage tank, and both sides of the guide block are designed with inclined surfaces and are inclined outward at the same time.

[0013] As a further improvement of the above solution, guide rods are symmetrically fixedly connected to the water tank, and guide blocks are symmetrically fixedly connected to the top of the liquid storage tank and are slidably connected to the guide rods.

[0014] As a further improvement of the above solution, the ends of the two groups of guide rods are fixedly connected to the same limiting plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The utility model drives the rotating shaft to rotate 180 degrees alternately forward and reversely through a stepper motor, so that the toggle plate can be driven to rotate. The rotation of the toggle plate can push the water in the water tank back and forth, so that the water can form waves. The waves moving back and forth can increase the contact area with the air, thereby improving the heat dissipation effect of the water, and the utility model is highly practical.

[0017] 2. The waves formed when the utility model dissipates heat from the water body will also regularly impact the connecting plate. After being impacted, the connecting plate will be displaced and push the liquid storage tank to move horizontally. The movement of the liquid storage tank drives the vertical plate to move. The movement of the vertical plate drives the annular sponge to move outside the horizontal section of the water outlet pipe, thereby removing the dust covering its surface, effectively avoiding the effect of the water outlet pipe on radiating heat to the outside due to dust accumulation, and further improving the practicability of the device.

[0018] 3. In the process of cleaning the dust on the outside of the horizontal section of the water outlet pipe, the volatile liquid in the liquid storage tank will flow into the inside of the vertical plate and penetrate into the inside of the annular sponge through the leakage hole. After the annular sponge absorbs the volatile liquid, it will be smeared on the outside of the horizontal section of the water outlet pipe as it moves. The volatile liquid evaporates and takes away the heat on the pipe, thereby further improving the heat dissipation capacity of the water body, thereby ensuring that the water body can always maintain a good cooling effect.

[0024] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0025] Embodiment 1:

[0026] Please combine Figure 1-3 , a rapid cooling sintering furnace of this embodiment includes:

[0027] A sintering furnace body 1, the outside of the sintering furnace body 1 is respectively fixedly sleeved with a spiral cooling pipe 2 and a spiral cooling pipe 3, a water tank 4 is arranged below the sintering furnace body 1, two groups of submersible pumps are fixedly installed inside the water tank 4, the water inlet ends of the spiral cooling pipe 2 and the spiral cooling pipe 3 are fixedly connected with a water inlet pipe 5, and the two groups of water inlet pipes 5 are respectively connected with the water outlets of the two groups of submersible pumps, the water outlet ends of the spiral cooling pipe 2 and the spiral cooling pipe 3 are fixedly connected with a water outlet pipe 6, and the two groups of water outlet pipes 6 are connected with the water tank 4, one side of the water tank 4 is fixedly connected with a stepping motor, the inside of the water tank 4 is rotatably connected with a rotating shaft 7, and one end of the rotating shaft 7 is coaxially fixedly connected with the rotor end of the stepping motor, and the outside of the rotating shaft 7 is fixedly connected with a toggle plate 8, which can cool the water body;

[0028] The dust removal and cooling assembly includes two sets of vertical plates 101 which are sleeved on the outside of the horizontal section of the water outlet pipe 6, and an annular sponge 102 is fixedly connected to the vertical plates 101. The tops of the two sets of vertical plates 101 are fixedly connected to the same liquid storage tank 103, and the top center of the liquid storage tank 103 is fixedly connected to a liquid injection pipe 104. One side of the liquid storage tank 103 is symmetrically fixedly connected to a cross bar 105, and the cross bar 105 is slidably connected to the water tank 4. A connecting plate 106 is provided inside the water tank 4, and the connecting plate 106 is fixedly connected to the two sets of cross bars 105 at the same time. A reset spring 107 is sleeved on the outside of the cross bar 105, and the two ends of the reset spring 107 are respectively fixedly connected to the outer wall of the water tank 4 and the liquid storage tank 103, and the vertical plate 101 is a hollow structure. The vertical plate 101 is connected to the bottom of the inner cavity of the liquid storage tank 103, and leakage holes 108 are evenly provided to facilitate the volatile liquid inside the vertical plate 101 to penetrate into the annular sponge 102. A guide block 109 is fixedly connected to the bottom of the inner cavity of the liquid storage tank 103. Both sides of the guide block 109 are inclined and tilted outward at the same time, which can prevent the volatile liquid from remaining in the liquid storage tank 103 and ensure that it can flow out completely. The water tank 4 is symmetrically fixedly connected with a guide rod 110, and the top of the liquid storage tank 103 is symmetrically fixedly connected with a guide block 111, which is slidably connected to the guide rod 110, which can play a certain guiding role in the horizontal movement of the liquid storage tank 103.

[0029] The implementation principle of a fast cooling sintering furnace in the embodiment of the present application is: first, start the submersible pump to transport water into the spiral cooling tube 1 2 and the spiral cooling tube 2 3 respectively to cool the sintering furnace body 1, and then start the stepper motor, and drive the rotating shaft 7 to rotate 180 degrees alternately forward and reversely through the stepper motor, so that the toggle plate 8 can be driven to rotate. The rotation of the toggle plate 8 can push the water in the water tank 4 back and forth, so that the water can form waves. The waves moving back and forth can increase the contact area with the air, thereby improving the heat dissipation effect of the water. At the same time, the waves will regularly impact the connecting plate 106. After being impacted, the connecting plate 106 will be displaced and push the liquid storage tank 103 to move horizontally and stretch the reset spring 107. The movement of the box 103 drives the vertical plate 101 to move, and the movement of the vertical plate 101 drives the annular sponge 102 to move outside the horizontal section of the water outlet pipe 6. When the waves move in the opposite direction, the rebound effect of the reset spring 107 will drive the annular sponge 102 to automatically reset, so that the dust covering its surface can be removed, and the volatile liquid inside the liquid storage box 103 will flow into the vertical plate 101 and penetrate into the annular sponge 102 through the leakage hole 108. After absorbing the volatile liquid, the annular sponge 102 will smear it on the outside of the horizontal section of the water outlet pipe 6 as it moves. The volatile liquid evaporates and takes away the heat on the pipeline, thereby further improving the heat dissipation capacity of the water body, thereby ensuring that the water body can always maintain a good cooling effect.

[0030] Embodiment 2:

[0031] Based on the first embodiment, the present embodiment is further improved in that the ends of the two groups of guide rods 110 are fixedly connected with the same limiting plate 112 to prevent the guide blocks 111 from being separated from the guide rods 110 .

[0032] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
