Description

Technical Field

[0002] Molybdenum has the advantages of high melting point and boiling point, good high temperature strength, anti-friction and corrosion resistance, high thermal conductivity, small thermal expansion coefficient, and good hardenability, making it widely used in aerospace, weapons, electronics, chemical industry and other fields. Molybdenum oxide can be used as steel additives, lubricants, catalysts, etc. In the process of producing and processing molybdenum compounds, in order to obtain the required type of molybdenum compounds, it is necessary to perform different processing on the molybdenum compounds produced and processed.

[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1 to Figure 2 As shown, a molybdenum compound screening device comprises a movably arranged screening box 1, wherein a screening net for screening produced molybdenum compounds and detachably mounted inside the screening box is installed inside the screening box 1, and the screening net is installed in the middle part of the interior of the screening box 1, and a bellows is connected through the top of the screening box 1, and a screening funnel 2 is connected at one end of the bellows away from the screening box 1, through which molybdenum compounds enter the screening box through the bellows. The screening box 1 is movably installed and connected to a screening bracket 3, and the screening funnel 2 is fixedly connected to the screening bracket 3. The molybdenum compounds to be screened are passed through the screening funnel 2, into the screening box 1 through the bellows expansion tube, and fall onto the screening net installed inside the screening box 1. Then, the screening box 1 is controlled to "vibrate" on the screening support 3, so as to "vibrate screen" the molybdenum compounds on the screening net, and the molybdenum compounds meeting the requirements (particle size) fall from the screening net to the bottom of the screening box 1 for unified collection and treatment.

[0020] Furthermore, in the embodiment, the screening box 1 designed and installed in the screening device is internally installed with a screening mesh for screening the produced molybdenum compounds and detachably installed inside the screening box 1. The screening mesh is installed in the middle part of the interior of the screening box 1. In this way, different screening meshes can be replaced according to the "particle size of the molybdenum compounds" to be screened, so that the molybdenum compounds passing through the screening mesh can meet the needs. At the same time, a bellows expansion tube is connected through the top of the screening box 1, and the end of the bellows expansion tube away from the screening box 1 is connected to a screening funnel 2 for molybdenum compounds to enter the screening box through the bellows expansion tube. The screening box 1 is movably installed and connected to the screening bracket 3, and the screening funnel 2 is fixedly connected to the screening bracket 3; by passing the molybdenum compounds from the screening funnel 2, entering the screening box 1 through the bellows expansion tube, and falling onto the screening net installed inside the screening box 1, and then by controlling the screening box 1 to "vibrate" on the screening bracket 3, the molybdenum compounds on the screening net are "vibrated and screened". In the embodiment, the bottom end of the screening box 1 is provided with a vibration device for driving the screening box 1 to move; and the vibration device includes a vibration motor 4, which is fixedly mounted on the bottom end surface of the screening support bottom plate 5, the screening support bottom plate 5 is connected to the screening bracket 3, and the bottom end of the screening support bottom plate 5 is connected with support columns for supporting and stabilizing the screening support bottom plate 5; the output end of the vibration motor 4 can move through the screening support bottom plate 5 and is connected to the bottom end of the screening box 1 through a movable structure. In this way, by controlling the "vibration movement" of the vibration motor 4, the vibration motor 4 drives the screening box 1 to "vibrate" on the screening bracket 3 through the movable structure, thereby "vibrating and screening" the molybdenum compounds on the screening net.

[0021] Further, in the embodiment, the movable structure of the arrangement includes a movable seat 6, one end of the movable seat 6 is connected to the output end of the vibration motor 4, the other end of the movable seat 6 is connected to the movable ball rod 61 through a ball joint structure, and the other end of the movable ball rod 61 is movably connected to the bottom end of the screening box 1 through the ball joint structure. At the same time, a deformation spring 62 is movably provided on the movable ball rod 61, one end of the deformation spring 62 is connected to the movable seat 6, and the other end of the deformation spring 62 is connected to the bottom end of the screening box 1. In this way, when the vibration motor 4 is controlled to "vibrate and move", the vibration motor 4 drives the movable seat 6 connected to the output end to move, thereby driving the movable ball rod 61 to "movably swing" through the movable seat 6 through the ball joint structure, and the movable ball rod 61 "movably swings" through the screening box 1 connected to the other end through the ball joint structure, thereby driving the screening net installed and connected in the screening box 1 to "vibrate and screen". In the embodiment, in order to ensure that the screening box 1 realizes "movable swing", support structures for supporting the limited screening box 1 are also provided on both sides and one end of the screening box 1. The support structure of the arrangement includes a support rod 11, one end of the support rod 11 is connected to a support beam 31 through a hinge seat, the support beam 31 is installed and connected to the screening bracket 3, and the other end of the support rod 11 is hinged to the lower part of the side wall of the screening box 1 through a hinge seat; and a protection spring 12 is passed through the support rod 11, one end of the protection spring 12 is connected to the hinge seat connected to the support beam 31, and the other end of the protection spring 12 is connected to the end of the support rod 11 away from the support beam. The support rods 11 of the "three" support structures are arranged to "actively hinge" the "three" side walls of the screening box 1, so that the screening box 1 can achieve "active swing" under the drive of the vibration motor 4 and remain stable on the screening bracket 3. When the molybdenum compounds after screening fall from the screening net to the bottom of the screening box 1, in order to facilitate the unified collection and processing of the molybdenum compounds after screening in the screening box 1, an outlet pipe is provided at the bottom of the screening box 1, one end of the outlet pipe is connected to the screening box 1 through-set, and the other end of the outlet pipe is used to connect the bellows telescopic pipe for the molybdenum compounds after screening to pass through. In this way, the molybdenum compounds after screening pass through the outlet pipe, and then are uniformly collected and processed through the bellows telescopic pipe connected to the outlet pipe. From the structural design of the screening device, the screening device is used to perform "closed" screening of the molybdenum compounds that need to be screened, thereby avoiding the waste of molybdenum compounds and protecting the health of processing and production personnel.
