[0002] When metal granulation uses water quenching to shape the molten metal, the molten metal drips from the melting furnace into the water quenching barrel to cool and shape, and the formed metal particles are discharged from the bottom of the water quenching barrel. The discharged metal particles generally need to be filtered and dried. For the water filtering process, a more common method is to set a drain box under the water quenching barrel, and a filter mesh structure is set at the bottom of the drain box. After water quenching, the metal particles mixed with cooling water fall directly along the bottom of the water quenching barrel into the drain box under the action of gravity, which will produce a large impact force on the filter mesh. Especially for the water quenching method in which the water inlet and outlet of the water quenching barrel are always open, the water flow rate falling into the drain box is large and the impact force is strong, which can easily cause the filter mesh to deform and damage and shorten its service life.

[0022] like Figure 1-Figure 6 As shown, the utility model provides a drain box, which includes a box body 1 and a filter screen 2, the box body 1 is provided with a feed port 13, a drain port 14 and a discharge port 15, the feed port 13 is located at the top of the box body 1, the filter screen 2 is arranged inside the box body 1 and below the feed port 13, the drain port 14 is located at the bottom of the box body 1 and below the filter screen 2, and the discharge port 15 is located at one side of the box body 1, which is used to discharge the drained material. When the drain box is used in the metal granulation water quenching process, the material is metal granules. A buffer plate 3 is also arranged inside the box body 1, the buffer plate 3 is located below the feed port 13 and between the filter screen 2 and the feed port 13, the width of the buffer plate 3 is smaller than the diameter or width of the feed port 13, and there is a gap between the buffer plate 3 and the feed port 13 and the filter screen 2 for the material and cooling water to pass through, so as to ensure that when the material falls on the buffer plate 3, it can be dispersed to the surroundings along the side of the buffer plate 3 and fall onto the filter screen.
[0023] When the drain box is used, since the buffer plate 3 is located below the feed port 13 and the width of the buffer plate 3 is smaller than the diameter or width of the feed port 13, the material mixed with water will first pass through the buffer plate 3 when falling from the top of the drain box along the feed port 13. Under the action of the buffer plate 3, the falling material is dispersed. Specifically, when the falling material passes through the buffer plate 3, part of the material falls on the buffer plate 3 and disperses to the surroundings along the side of the buffer plate 3 under the action of the continuous falling material and falls onto the filter screen 2. The material that does not contact the buffer plate 3 directly falls onto the filter screen 2 along the side of the buffer plate 3, realizing continuous buffering and dispersion of the falling material, reducing the impact force on the filter screen 2, reducing the deformation and damage of the filter screen 2, extending the service life of the filter screen 2, reducing the replacement frequency of the filter screen 2, and reducing the requirements for the material strength and installation support strength of the filter screen 2. Since the material can be dispersed when the material falls, the adhesion and local accumulation between the materials when falling are reduced, which is more conducive to the rapid drainage of water.
[0024] The width of the filter screen 2 is greater than the diameter or width of the feed port 13, ensuring that the dispersed materials can fall on different areas of the filter screen 2. Preferably, the width of the buffer plate 3 is greater than or equal to one third of the diameter or width of the feed port 13, ensuring that it can effectively buffer the dispersed materials.
[0025] The filter screen 2 is box-shaped or barrel-shaped, and an opening is provided on its side, and the opening is arranged toward the discharge port 15. The buffer plate 3 is specifically located in the filter screen 2. Since the filter screen 2 is box-shaped or barrel-shaped, its side wall also has the ability to drain water, and the materials dispersed to the surroundings can quickly drain water through the side wall of the filter screen 2. When the amount of materials discharged at a single time is large, or the materials are discharged continuously for drainage, the drainage speed of the filter screen 2 is faster.
[0026] like Figure 3 , Figure 5 and Figure 6 As shown, the bottom of the filter screen 2 is tilted downward toward the direction of the discharge port 15 to facilitate the drained material to move toward the discharge port 15 under the action of gravity.
[0027] The filter screen 2 includes a filter screen bottom plate 21 and three filter screen side plates 22. The filter screen bottom plate 21 is the bottom of the filter screen 2, that is, the filter screen bottom plate 21 is tilted downward in the direction of the discharge port 15. The three filter screen side plates 22 are correspondingly arranged on three sides of the filter screen bottom plate 21. Figure 5-Figure 6 As shown, the opening is formed between the two filter side plates 22 located on the opposite sides of the filter bottom plate 21 and the side of the filter bottom plate 21 where the filter side plate 22 is not provided, and the distance between the two filter side plates 22 located on the opposite sides of the filter bottom plate 21 gradually decreases from the side away from the opening to the side where the opening is located, so that the filter screen 2 forms a bucket-shaped structure as a whole, which improves the drainage efficiency and facilitates the movement of materials toward the discharge port 15.
[0028] The box body 1 is provided with a bracket 4 inside, and the filter 2 is placed on the bracket 4, for example, the bracket 4 is basket-shaped, and this arrangement can facilitate the disassembly and assembly of the filter 2. Preferably, when the filter 2 is placed on the bracket 4, the opening faces the discharge port 15, and the three filter side plates 22 and the filter bottom plate 21 are spaced from the inside of the box body 1, so that the drained water moves downward.
[0029] The box body 1 includes a box body 11 and a box cover 12, a drain port 14 is arranged at the bottom of the box body 11, a discharge port 15 is arranged at the side of the box body 11, a bracket 4 is arranged inside the box body 11, and after the filter screen 2 is placed on the bracket 4, there is a gap between the bottom of the filter screen 2 and the bottom of the box body 11 to form a drainage cavity. There are two drain ports 14, which are arranged at both sides of the bottom of the box body 11 to speed up the discharge of water and better suit for continuous material discharge and drainage operations. The box cover 12 is detachably arranged at the top of the box body 11, for example, covering the top of the box body 11 or hingedly arranged at the top of the box body 11, a feed port 13 is opened on the box cover 12, and a buffer plate 3 is arranged on the box cover 12, specifically arranged on the side of the box cover 12 facing the inside of the box body 11 through a bracket, and the buffer plate 3 can be moved synchronously after the box cover 12 is opened to prevent the buffer plate 3 from interfering with the disassembly and assembly of the filter screen 2.
[0030] The drain box also includes a baffle 5, which is arranged on one side of the box body 1 where the discharge port 15 is arranged, and the baffle 5 can move on the side of the box body 1 to open or close the discharge port 15. This arrangement can expand the use function of the drain box, and the discharge port 15 can be selected to be normally open or intermittently opened according to actual application requirements. When the amount of material per unit time is small, the discharge port 15 can be selected to be normally open. When the amount of material per unit time is large or it is a continuous material discharge and drainage operation, it is preferably intermittently opened to ensure that the water is drained as much as possible before discharging the material.
[0031] Among them, the baffle 5 is plugged into the box body 11, and specifically includes a driving member 6 for driving the baffle 5 to move. The driving member 6 is specifically any one of a pneumatic cylinder, an oil cylinder, and an electric cylinder. The working frequency is preset by an external controller, that is, it runs once at a fixed time interval, and its cylinder end is fixed to the side of the box body 11, and the moving end is connected to the upper end of the baffle 5 through a fixed block. The baffle 5 is driven to move along the plug-in position through telescopic movement to open the discharge port 15 to achieve intermittent discharge.
[0032] The drain box also includes a guide tube 7, one end of which is connected to the discharge port 15, and the other end of which is extended downward along the height direction of the box body 1. The guide tube 7 is used to guide the material discharged along the discharge port 15, so that the material can be discharged downward when the discharge port 15 is located on the side of the box body 11. Figure 3-Figure 5 As shown, it is a schematic diagram of the baffle 5 closing the discharge port 15, as shown in Figure 6 As shown, it is a schematic diagram of the opening of the discharge port 15 after the baffle 5 moves. At this time, the material guide cylinder 7 is connected with the inside of the filter screen 2, and the material moves downward along the material guide cylinder 7 through the discharge port 15, so that the material falls orderly into other mechanisms below the drain box and enters the next process.
[0033] The utility model also provides a metal granulation water quenching device, which includes a water quenching tank and a drain box as described above, wherein the feed port 13 of the drain box is connected to the discharge port at the bottom of the water quenching tank. The molten metal is poured out or flows out of the smelting furnace, falls into the cooling water in the water quenching tank, and is cooled and formed into metal particles. The metal particles are mixed with cooling water and discharged from the bottom discharge port and enter the drain box along the feed port 13 to drain water. During the drainage process, the buffer plate 3 can realize continuous buffering and dispersion of the falling materials, reduce the impact force on the filter screen 2, reduce the deformation and damage of the filter screen 2, extend the service life of the filter screen 2, reduce the replacement frequency of the filter screen 2, and reduce the requirements for the material strength and installation support strength of the filter screen 2. Since the materials can be dispersed when they fall, the adhesion and local accumulation between the materials when falling are reduced, which is more conducive to the rapid drainage of water.
