Description

Technical Field

[0001] This utility model relates to the technical field of tungsten and molybdenum parts production and processing equipment, and in particular to a raw material processing device for tungsten and molybdenum parts production and processing. Background Technology

[0002] In the production and processing of tungsten and molybdenum parts, a pusher-type reduction furnace is usually used to perform hydrogen reduction treatment on oxide raw materials (such as tungsten trioxide and molybdenum trioxide) to produce metal powder. The boat is a key carrier for the raw materials, and its performance directly affects the efficiency and quality of the reduction reaction.

[0003] Currently, most commonly used traditional boats and vessels are flat and shallow, which have the following shortcomings in use: 1. In order to ensure the full reduction of raw materials, only a certain thickness of raw materials can be spread in the boat. This means that when a large amount of raw materials are carried by the boat, the boat needs to be repeatedly loaded and transported when a large-scale reduction process is carried out, resulting in low raw material reduction efficiency. 2. The reducing gas (hydrogen) can only diffuse from the top layer of the raw material, resulting in insufficient reaction at the bottom and center of the material layer, poor reduction uniformity, and serious impact on the quality of subsequent products. 3. Under high temperature conditions, raw materials are prone to sintering and sticking to the bottom surface of the boat, which not only causes raw material loss, but also makes cleaning the boat extremely difficult and easily leads to cross-contamination between different batches of materials. Therefore, there is an urgent need for a raw material processing device for the production and processing of tungsten and molybdenum parts that can overcome the above-mentioned shortcomings. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model discloses a raw material processing device for the production and processing of tungsten and molybdenum parts. This utility model not only enables the reducing gas to diffuse evenly from the bottom of the boat to the top, effectively solving the problem of insufficient reduction at the bottom of the material layer, but also effectively prevents the raw material from sticking to the boat.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A raw material handling apparatus for the production and processing of tungsten and molybdenum parts includes a boat for holding the raw materials, and further includes: Multiple transverse grooves are located on the bottom surface of the vessel and are arranged parallel to each other. Both ends of the transverse grooves are open, forming a through airflow channel. Multiple pores are evenly distributed on the bottom surface of the boat-shaped dish. The multiple pores are connected to the corresponding transverse grooves to guide the reducing gas from bottom to top to the bottom of the raw material. A mesh screen, placed inside the boat, is used to support the raw materials and isolate them from the bottom surface of the boat. The base plate is detachably installed at the bottom of the vessel to support its stable operation and collect any leaked materials.

[0006] Furthermore, the transverse groove is provided with multiple reinforcing ribs spaced apart along its axial direction.

[0007] Furthermore, the bottom surface of the boat is provided with several raised arc surfaces that correspond to and are connected to the transverse grooves. A mesh is provided on the upper part of the raised arc surfaces, and adjacent raised arc surfaces cooperate with the mesh to form cavities. Air holes are provided on the raised arc surfaces and are connected to the adjacent cavities.

[0008] Furthermore, the bottom surface of the cavity is provided with a material feeding passage that penetrates the vessel.

[0009] Furthermore, the bottom surface of the vessel is provided with several longitudinal grooves that are perpendicular to and connected to the transverse grooves, and both ends of the longitudinal grooves are open structures.

[0010] Furthermore, the grid includes a frame and a screen disposed within the frame.

[0011] Furthermore, slots are provided on the lower inner walls at both ends of the vessel, and the two ends of the frame are respectively connected to the adjacent slots.

[0012] Furthermore, a collection groove is provided on the upper surface of the base plate.

[0013] Furthermore, several insertion rods are evenly distributed along the outer edge of the upper surface of the base plate, and insertion holes corresponding to the insertion rods are provided along the outer edge of the bottom surface of the boat.

[0014] Compared with the prior art, the beneficial effects of this utility model are: By setting a horizontal groove at the bottom and vents on the inner bottom surface, the reducing gas can enter from multiple directions at the bottom of the boat and penetrate the bottom layer of raw materials from bottom to top, which greatly shortens the gas diffusion path. This not only effectively solves the problem of insufficient reduction in the center and bottom of the material layer, but also significantly improves the uniformity and efficiency of the reduction reaction. In addition, it can also effectively increase the load of raw materials in the boat and improve the reduction efficiency of the boat. By setting up a mesh with a aperture smaller than that of the raw material particles, the raw material is supported and completely physically isolated from the bottom surface of the boat. This avoids the raw material from sintering and sticking to the boat body at high temperatures, ensuring that the bottom surface of the boat remains clean after unloading. This greatly reduces the difficulty and workload of cleaning and effectively prevents cross-contamination between different batches of materials. By setting up a base plate, not only can leaked fine raw material powder be collected, reducing the waste of valuable raw materials and preventing powder from leaking into the furnace and polluting the environment or damaging the equipment, but it also provides strong support for the smooth transport and operation of the boat. By setting up raised arc surfaces and cavities, the contact area between the reducing gas and the bottom layer of raw materials is greatly increased, thus providing a strong guarantee for the full reduction treatment of the bottom layer of raw materials. By setting longitudinal grooves to cooperate with transverse grooves to form a through airflow channel, reducing gas can enter from multiple directions at the bottom of the boat and penetrate the bottom layer of raw materials from bottom to top. By adding reinforcing ribs, the creep resistance and deformation resistance of the bottom of the boat are significantly enhanced at high temperatures, ensuring that the boat can maintain its shape stability and run smoothly during long-term use, thus extending its service life. This invention not only enables the reducing gas to diffuse evenly from the bottom of the boat upwards, effectively solving the problem of insufficient reduction at the bottom of the material layer, but also effectively prevents the raw material from sticking to the boat, providing strong support for the high-efficiency and high-quality hydrogen reduction treatment of tungsten and molybdenum parts raw materials.

[0017] The technical solution of this utility model will be described below with reference to the accompanying drawings of the embodiments of this utility model. In the description, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" indicating the orientation or positional relationship, they are only corresponding to the drawings of this utility model for the convenience of describing this utility model, and do not indicate or imply that the device or element referred to must have a specific orientation.

[0018] Please refer to the instruction manual appendix. Figure 1-4 This utility model provides a technical solution: Example 1: A raw material processing device for the production and processing of tungsten and molybdenum parts includes a boat 1 for carrying raw materials. The bottom surface of the boat 1 is provided with multiple transverse grooves 1.1, which are arranged along the length of the boat 1. Both ends of the multiple transverse grooves 1.1 are open to form a through airflow channel. The bottom surface of the boat 1 is provided with multiple air holes 1.2, which are arranged in a matrix. Each row of air holes 1.2 is respectively connected to the transverse grooves 1.1 on the bottom surface of the boat 1, for guiding the reducing gas from bottom to top to the bottom layer of raw materials. In order to enable the reducing gas to enter the airflow channel quickly and efficiently, the bottom surface of the boat 1 is provided with several longitudinal grooves 1.4 that are perpendicular to and connected to the transverse grooves 1.1. Both ends of the longitudinal grooves 1.4 are open structures. The transverse grooves 1.1 and the longitudinal grooves 1.4 are used to enable the reducing gas to enter the bottom of the boat 1 from all directions, thereby improving the reduction efficiency of the bottom raw materials. The boat dish 1 is provided with a mesh 2 laid flat on the bottom surface of the boat dish 1. The aperture of the mesh 2 is smaller than the size of the tungsten and molybdenum raw material. The mesh 2 utilizes the simple physical principle of "sieving effect" to not only support the raw material and effectively prevent the raw material from leaking through the pores 1.2, but also to isolate the raw material from the bottom surface of the boat dish 1, avoiding the raw material from sintering and sticking to the bottom surface of the boat dish 1 at high temperature. This effectively solves the problems of easy contamination and difficult cleaning of the boat dish 1. The bottom of the boat 1 is detachably fitted with a base plate 3. Specifically, several insert rods 3.2 are evenly distributed along the outer edge of the upper surface of the base plate 3. The bottom surface of the boat 1 has insertion holes 1.5 that correspond to and fit the insert rods 3.2 one by one along the outer edge. The base plate 3 is set parallel to the boat 1, which does not block the airflow channel at the bottom of the boat 1 and provides strong support for the smooth transport of the boat 1. The upper surface of the base plate 3 is also provided with a collection groove 3.1, which can collect the raw materials that leak through the mesh 2 and the air holes 1.2.

[0019] In Example 2, in order to improve the structural strength of the boat 1 and prevent it from deforming under high temperature conditions, a plurality of reinforcing ribs 1.1.1 are provided in the transverse groove 1.1 at intervals along its axial direction. The reinforcing ribs 1.1.1 can further strengthen the transverse groove 1.1 and effectively prevent the bottom of the boat 1 from sinking and deforming.

[0020] In Example 3, in order to ensure that the bottom layer of the raw material can fully and uniformly contact the reducing gas and improve the reduction quality of the raw material, the bottom surface of the boat 1 is provided with several raised arc surfaces 1.6 that correspond one-to-one with the transverse grooves 1.1 and are connected to the corresponding transverse grooves 1.1. The grid 2 is provided on the upper part of the raised arc surfaces 1.6, and the adjacent raised arc surfaces 1.6 cooperate with the grid 2 to form cavities 1.7. The air holes 1.2 are provided on the raised arc surfaces 1.6 and are connected to the adjacent cavities 1.7. The reducing gas enters the cavity 1.7 through the vent 1.2, and then comes into contact with the bottom layer of raw materials through the mesh 2 at the top of the cavity 1.7. The design of the cavity 1.7 greatly increases the contact area between the reducing gas and the bottom layer of raw materials, thus providing strong support for the full reduction of the bottom layer of raw materials. To prevent some raw materials from falling into the cavity 1.7 through the mesh 2 and accumulating, a feeding passage 1.7.1 penetrating the boat 1 is provided on the bottom surface of the cavity 1.7. The feeding passage 1.7.1 has a structure that is wider at the top and narrower at the bottom. The setting of the feeding passage 1.7.1 not only allows leaked raw materials to fall quickly into the collection tank 3.1 on the bottom plate 3 for collection, but also allows reducing gas to enter the cavity 1.7 through the feeding passage 1.7.1 and fully contact the bottom of the raw materials.

[0021] In Example 4, to facilitate the daily disassembly, cleaning and maintenance of the mesh 2, the mesh 2 includes a frame 2.1 and a screen 2.2 set in the frame 2.1. The lower side of the inner wall of both ends of the boat 1 is provided with a slot 1.3. Both ends of the frame 2.1 are respectively connected to the adjacent slot 1.3. By using the slot 1.3 to connect the two ends of the frame 2.1, the mesh 2 can be disassembled conveniently and efficiently.
