Description

Technical Field

[0001] The invention relates to the technical field of granulators, in particular to a chute turning mechanism for a granulator. Background Art

[0002] In the prior art, the stability of the working of the pellet mill as the core equipment of feed production is of self-evident importance to the quality of the finished feed product, and the chute that guides the feed also plays an important role in the stability of the working of the pellet mill.

[0003] Defects and shortcomings of the existing technology:

[0004] Existing pelletizer chute Figure 1 and Figure 2 As shown, the flap 3 is rotatably connected in the chute to block the feed port 11 and the bypass outlet 12. When the powder entering from the feed port 11 does not need to enter the granulator pressing chamber, but needs to be discharged from the bypass outlet 12, this structure will result in most of the material being discharged from the bypass outlet 12, and a small part of the material entering the granulator pressing chamber from the granulation inlet 13 along the flow plate 2. This will cause some problems, such as the need to add steam to the material before starting the machine. The material will form lumps due to the presence of steam. Once the lumped wet material enters the pressing chamber, it will cause the granulator to slip when started, which will seriously block the machine and affect normal production. In addition, when the formula needs to be changed and the cleaning process is required, a large amount of material does not need to be granulated and needs to flow into the next process through the bypass. Since it cannot be sealed, a large amount of material enters the pressing chamber. It will take a lot of manpower time to clean the pressing chamber the next time the machine is started. Once the cleaning is forgotten, the machine may not be able to start. Summary of the invention

[0005] In order to solve the problem in the prior art that part of the material enters the granulation pressing chamber during bypass discharge, the present invention provides a granulator chute flipping mechanism that realizes the mutual independence of the material channel entering the pressing chamber and the material channel entering the bypass outlet.

[0006] The technical solution adopted by the present invention to solve its technical problem is:

[0007] A granulator chute turning mechanism, comprising:

[0008] A machine body, a feed inlet arranged above the machine body, a bypass outlet arranged below the machine body, and a granulation inlet arranged on the side of the machine body and connected to a granulator pressing chamber;

[0009] A first channel, wherein the first channel connects the feed inlet with the granulation inlet;

[0010] a second channel, wherein the second channel connects the feed inlet with the bypass outlet;

[0011] The flip door is arranged inside the machine body and is rotatably connected to the machine body to realize the connection switching between the first channel and the second channel.

[0012] Furthermore, the flip door is connected to a rotating shaft, and the rotating shaft extends from the body and is connected to a driving mechanism for driving the rotating shaft.

[0013] Furthermore, the driving mechanism includes a cylinder fixed on the body, a swivel arm is connected between the piston rod of the cylinder and the rotating shaft, the first end of the swivel arm is fixedly connected to the rotating shaft, and the second end of the swivel arm is hinged to the piston rod of the cylinder.

[0014] Furthermore, a hinge seat is fixed to the end of the piston rod, and the second end of the rotating arm is connected to the hinge seat.

[0015] Furthermore, a front baffle and a rear baffle are provided in the body, and when the first channel is fully connected, the upper end of the flip door abuts against the rear baffle, and when the second channel is fully connected, the upper end of the flip door abuts against the front baffle.

[0016] Furthermore, a limit plate is provided in the machine body, and the limit plate extends obliquely from the lower end of the granulation inlet, and when the first channel is connected, the flip door is closely attached to the lower side of the limit plate.

[0017] Furthermore, the rear baffle includes a first baffle fixed on the machine body. When the first channel is fully connected, the edge of the flip door is in close contact with the surface of the first baffle; and the angle between the flip door panel and the first baffle panel is an acute angle. The angle between the flip door panel and the first baffle panel is an acute angle, so that the flip door and the first baffle are clamped. In the circumferential direction of the flip door, due to the acute angle, the flip door cannot continue to rotate. The flip door is held by the first baffle in the radial direction. In addition, the limiting effect of the limiting plate provides a good overall limiting effect of the flip door.

[0018] Furthermore, the rear baffle further comprises a second baffle, one end of the second baffle is fixedly connected to the machine body, and the other end of the second baffle is fixedly connected to the first baffle. The second baffle is connected between the first baffle and the machine body to increase strength.

[0019] Furthermore, the upper surface of the flip door is bent upward, and the bending centerline is located at the rotation center of the flip door. The bending design of the flip door can, on the one hand, match the shape of the limit plate and the first baffle and fit them together, and on the other hand, the upwardly bent flip door has a larger load-bearing capacity, which prevents the flip door from being bent due to the long-term impact of the material on the flip door, causing a gap between the flip door and the front baffle or the rear baffle, resulting in the first channel and the second channel being unable to be completely independent.

[0020] Furthermore, a reinforcing rib plate is provided at the lower end of the flip door, which increases the overall strength of the flip door and improves the bearing capacity of the flip door.

[0021] Beneficial effects:

[0022] (1) The present invention separates the first channel and the second channel by setting a flip door, thereby realizing two independent channels so that the materials enter the pressing chamber and flow out from the bypass outlet respectively, and there will be no cross flow of materials;

[0023] (2) The independent first channel and the second channel are switched by a flip door, which is convenient to switch. The flip door presses against the front baffle or the rear baffle and the limit plate at the same time to achieve separation and limit. There will be no crossover of materials, and the machine can be started quickly. BRIEF DESCRIPTION OF THE DRAWINGS
