Description

Technical Field

[0001] This utility model relates to the field of graphite crucible production technology, specifically to a graphite crucible cooling water extrusion device. Background Technology

[0002] In the production and use of graphite crucibles, the cooling process is crucial. Traditional crucible cooling methods often employ spray cooling. After cooling, the crucible is usually filled with cooling water. If some of this cooling water is not drained, it can easily overflow from the top of the crucible during subsequent transport, polluting the production environment. Therefore, existing cooling equipment typically has a cooling water extrusion device at the outlet to squeeze out some of the cooling water from the crucible, preventing overflow during transport. The crucible is then transferred to a tilting device to pour the remaining water into a water tank. The extrusion device has a simple structure, mainly consisting of a cylinder mounted on a frame and a water-squeezing head on the cylinder's output rod. When the crucible arrives below the water-squeezing head via the conveyor, the cylinder drives the water-squeezing head to move down and insert into the crucible, thereby squeezing out most of the cooling water inside the crucible. However, during the extrusion of cooling water, the cylinder's output rod cannot move too fast, otherwise the cooling water will fly out from the gap between the water-squeezing head and the crucible, easily causing the cooling water to fly out of the equipment and pollute the production environment. Reducing the movement speed of the cylinder's output rod will greatly reduce the extrusion efficiency of the cooling water, thereby reducing the crucible's production efficiency.

[0003] To address this issue, we have designed a graphite crucible cooling water extrusion device. Utility Model Content

[0012] Compared with the prior art, the present invention provides a graphite crucible cooling water extrusion device, which has the following beneficial effects: Compared to existing cooling water extrusion devices, this graphite crucible cooling water extrusion device can appropriately increase the movement speed of the cylinder output rod, thereby improving the extrusion efficiency of the crucible cooling water.

[0015] 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.

[0016] Example 1: Please refer to Figures 1-5A graphite crucible cooling water extrusion device includes an extrusion structure. A cover 1 in the extrusion structure is mounted on top of a chain conveyor 9. The cover 1 has inlets and outlets at the front and rear. A vertically mounted cylinder 2 is installed on its top, connected to an external cylinder control system. The output rod of the cylinder 2 is located inside the cover 1 and connected to a connecting rod 3. A baffle 5 is fixed near the top of the connecting rod 3, and an extrusion head 4 is fixed at its bottom. The extrusion head 4 is a cylindrical shell made of aluminum alloy, covered with a rubber pad to prevent accidental scratching of the crucible body 14. The outer radius of the extrusion head 4 is smaller than the inner radius of the crucible body 14. The cylinder 2 drives the extrusion head 4 at the bottom of the connecting rod 3 to move up and down, facilitating insertion of the extrusion head 4 into the crucible body 14. 4. The water-squeezing head 4 is inserted into the crucible body 14, thereby squeezing out the water inside. A downward-facing water-retaining cover 6 is provided outside the water-squeezing head 4. The water-retaining cover 6 is made of aluminum alloy and has a waterproof coating to protect it and prevent rust. The inner radius of the water-retaining cover 6 is larger than the outer radius of the crucible body 14. A through hole for the connecting rod 3 to pass through is provided on the water-retaining cover 6. A sealing ring is fixed inside the through hole to seal the gap between the through hole and the connecting rod 3. When the water-squeezing head 4 moves downward, the water-retaining cover 6 moves downward with it. When the water-squeezing head 4 is inserted into the crucible body 14, the water-retaining cover 6 covers the crucible body 14, preventing water inside the crucible body 14 from splashing out of the cover 1 from the inlet and outlet. Four rectangular... The support columns 8 are arranged in a shaped array. A rubber pad is attached to the bottom of each support column 8. A spring 7 is fitted onto the connecting rod 3. The spring 7 is located between the baffle 5 and the water-blocking cover 6 and is always under compression. When the squeezing head 4 and the water-blocking cover 6 descend to a certain height, the support column 8 contacts the top of the crucible body 14, restricting the water-blocking cover 6 from moving further downwards. The squeezing head 4 and the connecting rod 3 can then continue to move downwards until the squeezing head 4 is completely inside the crucible body 14. During this process, the spring 7 is compressed. This design ensures sufficient space between the top of the crucible body 14 and the top of the inner cavity of the water-blocking cover 6 for water drainage, preventing the top of the inner cavity of the water-blocking cover 6 from covering the top opening of the crucible body 14 and affecting drainage. When the squeezing head 4 moves upwards, the water-blocking cover... Under the combined action of its own weight and the elastic force of spring 7, the water shield 6 will return to its inner cavity top and contact the top of the squeezing head 4. Four vertically arranged guide rods 11 are fixed on the top of the squeezing head 4 in a circular array. The top of the water shield 6 is provided with guide holes for these four guide rods 11 to pass through. The arrangement of the guide rods 11 can ensure the stability of the water shield 6 sliding on the connecting rod 3. A sealing ring is fixed inside each guide hole to seal the gap between the guide hole and the guide rod 11. The crucible body 14 can be placed on the top of the conveyor chain of the chain conveyor 9. The crucible body 14 can be conveyed forward by the chain conveyor 9 and pass through the inlet and outlet of the cover 1. A water tank 10 is installed on the bottom plate of the chain conveyor 9. Four support legs 12 arranged in a rectangular array are fixed at the bottom of the water tank 10.A drain outlet 13 is provided at the bottom of the water tank 10, which is connected to a drainage pipe. Water squeezed out of the crucible body 14 falls into the water tank 10 through the conveyor chain of the chain conveyor 9, and finally drains into the drainage pipe through the drain outlet 13 at the bottom of the water tank. A position sensor for monitoring the position of the crucible body 14 is installed on the inside of the cover 1. The control system of the cylinder 2, the chain conveyor 9, and the position sensor inside the cover 1 are all connected to an external controller. When the position sensor detects that the crucible body 14 has moved directly below the squeezing head 4, it transmits a signal to the controller. The controller immediately shuts down the chain conveyor 9 and starts the cylinder 2, which drives the squeezing head 4 to move downward to complete the squeezing operation. Then, the controller controls the cylinder 2 to reset and restart the chain conveyor 9.

[0017] Operating Procedure: When using this graphite crucible cooling water extrusion device, the crucible body 14, after being cooled by cooling water, is fed into the cover 1 via a chain conveyor 9. When the displacement sensor inside the cover 1 detects that the crucible body 14 has moved directly below the extrusion head 4, the chain conveyor 9 stops working. At the same time, the cylinder 2 at the top of the cover 1 starts, driving the connecting rod 3 to move the extrusion head 4 and the water baffle 6 downwards together until the extrusion head 4 is completely inside the crucible body 1. During this process, after the extrusion head 4 moves downwards into the crucible body 14... The water squeezes out most of the water inside the crucible body 14, while the water baffle 6 always covers the crucible body 14, which can effectively prevent the squeezed water from splashing outward. The squeezed water will fall into the water tank 10 through the chain plate of the chain conveyor 9, and finally be discharged through the drain outlet and drain pipe at the bottom of the water tank 10. After the water squeezing work is completed, the cylinder 2 is started again, driving the connecting rod 3 to move the water squeezing head 4 and the water baffle 6 upward together until they return to their original positions. Then the chain plate conveyor 9 is started again to send the crucible body 14, which has completed the water squeezing, out of the cover 1.

[0018] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
