Description

Technical Field

[0001] The utility model provides ammonium molybdate production screening equipment, belonging to the technical field of ammonium molybdate production. Background Art

[0002] Ammonium molybdate is an inorganic compound composed of ammonium ions and molybdate ions. Ammonium molybdate is usually a colorless crystal or crystalline powder, soluble in water and hot water, but insoluble in alcohol solvents. Ammonium molybdate has a wide range of applications, including catalysis, analytical chemistry and agriculture.

[0003] In the production process of ammonium molybdate, screening and classification of powder particles are essential. Ammonium molybdate is a hygroscopic compound that is prone to agglomeration in a humid environment. For agglomerated ammonium molybdate, the agglomerates need to be broken before they can be screened. However, the agglomerates are often hidden inside the ammonium molybdate powder, and it is often laborious to find the agglomerates and then break them; if the ammonium molybdate powder containing agglomerates is directly crushed, it will cause greater pressure on the crushing structure and be inefficient, affecting the screening efficiency. Utility Model Content

[0004] The utility model provides ammonium molybdate production screening equipment, wherein a movable crushing structure is arranged above the screening structure, and the remaining lumps can be crushed after most of the ammonium molybdate powders are screened, thereby reducing the crushing pressure and improving the crushing efficiency and the screening efficiency.

[0005] In order to solve the above problems, the utility model proposes a technical solution: an ammonium molybdate production screening device, comprising a bottom plate, the bottom plate is connected to a support frame that moves upward, and a screening drum is arranged in the support frame; a lifting plate is arranged in the support frame for sliding up and down, and a crushing motor is arranged on the lifting plate; a rotating shaft located above the screening drum is fixedly connected to the output shaft of the crushing motor, and a crushing rod is fixedly connected to the rotating shaft; a vibration motor is arranged on the screening drum, and a screening net is arranged at the bottom of the screening drum; a fixed column is fixedly connected to the bottom plate upward, and connecting blocks are fixedly connected to both sides of the screening drum; the connecting blocks are slidably sleeved on the fixed columns, and a vibration spring located below the connecting block is sleeved on the fixed columns.

[0006] As an improvement, a lifting motor is provided on the support frame, and a rotating screw located in the support frame is fixedly connected to the output shaft of the lifting motor; a moving plate is threadedly connected to the rotating screw, and a connecting rod fixedly connected to the lifting plate is fixedly connected below the moving plate.

[0007] As an improvement, a limiting rod is fixedly arranged in the support frame, and the movable plate is slidably sleeved on the limiting rod.

[0009] As an improvement, a slide groove is provided in the bottom plate, a receiving box is slidably arranged in the slide groove, and the receiving box is located below the screening cylinder.

[0010] As an improvement, two vibration motors are provided, and two groups of fixing columns and their connecting structures are provided.

[0011] Beneficial effects of the utility model:

[0012] 1. A lifting plate is set up in the support frame to slide up and down, and a crushing motor is set on the lifting plate; by setting the lifting plate, the crushing structure can be easily driven to move up and down. After the screening cylinder has screened the ammonium molybdate powder, a small amount of large particles and agglomerated ammonium molybdate remain in the screening cylinder. At this time, the crushing structure can enter the screening cylinder to crush them, which can reduce the crushing pressure and improve the crushing efficiency and screening efficiency.

[0013] 2. The connecting block is slidably sleeved on the fixed column, and the fixed column is sleeved with a vibration spring located below the connecting block; the setting of the vibration spring can increase the instability of the screening drum during vibration, thereby achieving better screening effect and avoiding clogging of the screening net to a certain extent.

DETAILED DESCRIPTION

[0018] The utility model is further described below in conjunction with the accompanying drawings.

[0019] according to Figure 1-3As shown: The utility model provides a screening device for ammonium molybdate production: comprising a bottom plate 1, the bottom plate 1 is connected with a support frame 2 which moves upward, and a screening drum 7 is arranged in the support frame 2; a lifting plate 5 is arranged in the support frame 2 which slides up and down, and a crushing motor 4 is arranged on the lifting plate 5; a rotating shaft 6 located above the screening drum 7 is fixedly connected to the output shaft of the crushing motor 4, and a crushing rod 3 is fixedly connected to the rotating shaft 6; a vibration motor 16 is arranged on the screening drum 7, and a screening net 18 is arranged at the bottom of the screening drum 7; a fixed column 17 is fixedly connected to the bottom plate 1 upward, and connecting blocks 8 are fixedly connected on both sides of the screening drum 7; the connecting blocks 8 are slidably sleeved on the fixed columns 17, and a vibration spring 20 located below the connecting blocks 8 is sleeved on the fixed columns 17. Two vibration motors 16 are arranged, and two groups of fixed columns 17 and their connecting structures are arranged.

[0020] A movable crushing structure is arranged above the screening structure, which can crush the remaining lumps after most of the ammonium molybdate powders are screened, thereby reducing the crushing pressure and improving the crushing efficiency and the screening efficiency.

[0021] The support frame 2 is provided with a lifting motor 14, and a rotating screw 15 located in the support frame 2 is fixedly connected to the output shaft of the lifting motor 14; a moving plate 12 is threadedly connected to the rotating screw 15, and a connecting rod 11 fixedly connected to the lifting plate 5 is fixedly connected below the moving plate 12. A limit rod 13 is fixedly provided in the support frame 2, and the moving plate 12 is slidably sleeved on the limit rod 13.

[0022] The setting of the limit rod 13 can limit the rotation of the moving plate 12 , thereby converting the rotation of the rotating screw 15 into the movement of the moving plate 12 , and transmitting the movement to the lifting plate 5 through the connecting rod 11 .

[0023] A limiting block 19 fixedly connected to the fixing column 17 is arranged above the connecting block 8 to prevent the connecting block 8 from being separated from the fixing column 17 .

[0024] A chute 10 is provided in the bottom plate 1, and a receiving box 9 is slidably provided in the chute 10, and the receiving box 9 is located below the screening cylinder 7. The setting of the receiving box 9 can play the role of storing the screened ammonium molybdate powder.

[0025] Principle of the utility model

[0026] When the utility model is used, the ammonium molybdate powder with agglomerates is directly added into the screening drum 7, and the vibration motor 16 is started to drive the screening drum 7 to vibrate. The setting of the vibration spring 20 can increase the instability of the screening drum 7, so that the screening effect is better; the ammonium molybdate powder that meets the screening particle size falls into the receiving box 9 through the screening net 18 under the action of vibration; and the larger ammonium molybdate powder particles and agglomerated ammonium molybdate are retained in the screening drum 7.

[0027] When the ammonium molybdate powder in the screening cylinder 7 is basically screened, and only a small amount of large particles, ammonium molybdate and agglomerated ammonium molybdate remain in the screening cylinder 7, turn off the vibration motor 16; start the lifting motor 14, so that the lifting plate 5 moves downward under the drive of the moving plate 12 until the rotating shaft 6 and the crushing rod 3 are inserted into the screening cylinder 7; start the crushing motor 4, so that the crushing rod 3 crushes the ammonium molybdate agglomerates in the screening cylinder 7; since only a small amount of large particles of ammonium molybdate and agglomerated ammonium molybdate remain in the screening cylinder 7 at this time, the crushing resistance of the crushing structure to the ammonium molybdate agglomerates is small, reducing the crushing pressure of the crushing structure, and at the same time, the crushing efficiency is higher and the screening efficiency can be improved. After the agglomerates are crushed, the lifting motor 14 is reversed, the crushing structure is removed from the screening cylinder 7, and the vibration motor 16 is restarted to perform secondary screening on the ammonium molybdate powder.

[0028] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
