Description

Technical Field

[0001] This utility model relates to the field of mixer technology, and in particular to a vertical mixer with a filter screen for pellet production. Background Technology

[0002] One of the important methods for pelletizing ore powder is to first add an appropriate amount of water and binder to the ore powder to form green pellets with uniform viscosity and sufficient strength. After drying and preheating, the green pellets are roasted in an oxidizing atmosphere to agglomerate and form pellets. The raw materials used for pelletizing are an important step that affects the quality of the pellets. If the existing raw materials are directly added to the mixer, large pieces or clumps of impurities will enter the mixer, increasing the mixing burden on the mixer and resulting in insufficient mixing of the mixture, which will affect the quality of the pellets. Therefore, the raw materials need to be screened and filtered before being added to the inside of the mixer.

[0003] An existing vertical mixer for pellet production with a filter screen (publication number: CN216827054U) has at least the following drawbacks:

[0004] In the aforementioned patent, the raw materials are screened by the cooperation of a filter mechanism and a pusher plate. Large or clump-like impurities are pushed by the pusher plate and fall from the discharge trough into the collection box for collection. However, the top surface of the circular plate of the filter mechanism is relatively flat, making it difficult for the raw materials to spread out and turn quickly. At the same time, the raw materials may clog the circular holes and prevent them from being filtered out. The rotating pusher plate carries large or clump-like impurities and raw materials out of the discharge trough, resulting in waste of raw materials and poor screening effect, which has certain limitations. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a vertical mixer with a filter screen for pellet production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A vertical mixer for pellet production with a filter screen includes a support frame, a mixer is disposed on one side of the support frame, a PLC controller is fixedly installed on the outer circular wall of the mixer, and a screening component for screening raw materials is also included. The screening component is disposed inside the support frame and includes a screening chamber disposed inside the support frame.

[0008] As a further embodiment of this utility model, the screening assembly further includes two first fixing plates fixedly installed on both sides of the screening chamber and both sides inside the support frame. The support frame has a plurality of ball-head rods inside. A spherical groove is formed on the top surface of the first fixing plate, and the spherical groove is movably sleeved with the ball-head rod.

A support pipe frame 14 is fixedly installed inside the support frame 1. A rotating frame 15 is movably sleeved on the inner circular wall of the support pipe frame 14. A second fixed pipe 16 is fixedly installed on the bottom surface of the screening bin 3. The second fixed pipe 16 is movably sleeved with the rotating frame 15.

[0028] In this embodiment, a hopper 23 is fixedly installed on one side of the support frame 1, a storage hopper 24 is provided on one side of the support frame 1, a number of support pads 25 are fixedly installed on the bottom surface of the support frame 1, a number of connecting plates 21 are fixedly installed on the outer circular wall of the mixer 2, the connecting plates 21 are fixedly installed with the support frame 1, a first fixing tube 10 is fixedly sleeved on the inner circular wall of the support hole 26, and grease is coated between the spherical groove 5 and the ball head rod 6.

[0029] From the above description, it can be seen that the above-described embodiments of this utility model achieve the following technical effects: When the user needs to screen large or clump-like impurities in the raw material using the support frame 1, the user starts the drive motor 17 to drive the first pulley 18 to rotate, which in turn drives the transmission belt 20, the second pulley 19, and the rotating frame 15 to rotate. The rotating frame 15 then drives the second fixed pipe 16 and the screening chamber 3 to perform circular motion. Simultaneously, the ball-head rod 6 and the first fixed plate 4 suspend the screening chamber 3, causing it to swing under the influence of the rotating frame 15. The user then feeds the raw material into the top left side of the screening mesh frame 7. The top surface of the screening mesh frame 7 has a certain slope, causing the raw material to spread out and be sieved on the top surface of the screening mesh frame 7, gradually moving downwards along the slope. This allows for the screening of larger impurities. Impurities are screened out and discharged downwards through the collection bin 11 and discharge hole 12 into the collection hopper 23 and stored in the storage hopper 24. The raw material falls downwards onto the top surface of the inclined plate 9, which also has a certain slope. Thus, the raw material gradually flows downwards into the fixed bin 8 and flows into the feed inlet on the top surface of the mixer 2 through the first fixed pipe 10. This completes the screening of the raw material. Therefore, starting the mixer 2 can mix the raw material, thereby achieving the effect of screening the raw material. The constantly swaying screening frame 7 can make the raw material spread out and turn over quickly, avoiding the accumulation of raw material and blockage. This allows the raw material to be fully screened and fall onto the top surface of the inclined plate 9 into the mixer 2. It is not carried away by large impurities and is discharged through the discharge hole 12, avoiding waste of raw material. This makes it convenient to use and quite practical.
