Description

Technical Field

[0001] This utility model relates to the field of cement production technology, specifically to a feeding device that can adjust the direction of cement clinker. Background Technology

[0002] In modern industrial production systems, the efficiency of material conveying and processing directly affects overall production efficiency. This is especially true in the manufacturing of heavy building materials such as cement, where clinker, as a core processing material, is crucial for the stability of its feeding process, which is essential for subsequent key processes such as grinding and pulverizing. As cement production shifts towards large-scale, high-efficiency, and low-consumption operations, traditional feeding devices are gradually revealing their inadequacy.

[0003] When the grinding speed of cement clinker is greater than the conveying speed, the cement clinker will directly impact the grinding roller. Existing technology uses the adjustment of the clinker direction to avoid the clinker directly impacting the grinding roller. However, all the clinker impacting the inner wall of the feed hopper causes great wear to the inner wall, and the life of the feed hopper is greatly reduced. Utility Model Content

[0004] In order to solve the technical problem that the existing technology uses the method of adjusting the clinker direction to avoid the clinker directly impacting the grinding roller, but all the clinker impacts the inner wall of the feed hopper, resulting in large wear on the inner wall and a significant reduction in the life of the feed hopper, this utility model provides a feeding device that can adjust the direction of cement clinker.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable cement clinker feeding device, comprising: a feeding hopper, two mirror-arranged guide plates connected to the middle of the feeding hopper, a discharge hopper connected to the lower end of the feeding hopper, the discharge port formed by the two guide plates being opposite to the discharge port of the discharge hopper, a grinding roller provided at the lower part of the discharge hopper, a distribution plate connected to the inner wall of the feeding hopper between the two guide plates, the lower end of the distribution plate being hinged to the upper end of the two guide plates, a bidirectional cam provided between the two guide plates, the bidirectional cam being connected to a rotating shaft, the rotating shaft being rotatably connected to the side wall of the feeding hopper, the rotating shaft being connected to the output end of a servo motor, and the bidirectional cam being able to synchronously lift the two guide plates when rotating.

[0006] Preferably, the two guide plates have a rotating shaft groove and a cam groove on their opposite surfaces, with the bidirectional cam located in the cam groove and the rotating shaft located in the rotating shaft groove.

[0007] Preferably, the upper end of the material distribution plate is provided with a symmetrical beveled edge.

[0008] Preferably, the lower side wall of the feed hopper is connected to two symmetrically arranged roller receiving cylinders. The side wall of the roller receiving cylinder is rotatably connected to a roller shaft, and a roller is connected to the roller shaft inside the roller receiving cylinder. The roller contacts the inner wall of the roller receiving cylinder, and when the guide plate is lifted, it can guide the clinker to directly hit the roller.

[0009] Preferably, the bidirectional cam is magnetic, and the guide plate is made of ferromagnetic metal.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] The clinker discharged from the guide plate is divided into two by the dividing plate. During normal production, it is consistent with the downward discharge method of existing technology. When the grinding speed is greater than the conveying speed, the bidirectional cam is rotated 90° by the servo motor. The two guide plates are simultaneously lifted by the bidirectional cam and guided to the inner wall of the feed hopper on both sides. By diverting the clinker, the impact and wear on the inner wall of the feed hopper are greatly reduced, and the service life of the feed hopper is extended.

[0012] A rotating roller was added, and the guide plate guides the cement clinker to the rotating roller. The rotating roller rotates and the impact point changes continuously, which avoids impact on the inner wall of the feed hopper and extends the service life of the rotating roller. Moreover, the replacement of the rotating roller is more convenient than the replacement of the feed hopper. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] The rotary connection described in this device refers to the axial fixation of the bearing by mounting the bearing on the shaft, with a spring retaining ring groove provided on the shaft or shaft hole, and the rotation achieved by locking the elastic retaining ring in the retaining ring groove; the hinge connection refers to the connection method that allows movement through connecting parts such as hinges, pins, and short shafts.

[0019] The present invention will now be described in detail with reference to the accompanying drawings.

[0020] The following is in conjunction with the appendix Figure 1-3 This embodiment describes an adjustable cement clinker feeding device, comprising: a feeding hopper 1, with two mirror-image guide plates 2 connected to the middle of the feeding hopper 1, a discharge hopper 3 connected to the lower end of the feeding hopper 1, the discharge port formed by the two guide plates 2 being opposite to the discharge port of the discharge hopper 3, a grinding roller being provided at the lower part of the discharge hopper 3, a distribution plate 4 being connected to the inner wall of the feeding hopper 1 between the two guide plates 2, the lower end of the distribution plate 4 being hinged to the upper end of two guide plates 5, a bidirectional cam 6 being provided between the two guide plates 5, the bidirectional cam 6 being connected to a rotating shaft 7, the rotating shaft 7 being rotatably connected to the side wall of the feeding hopper 1, and the rotating shaft 7 being connected to the output end of a servo motor, the bidirectional cam 6 being able to synchronously lift the two guide plates 5 when rotating.

[0021] Clinker is injected from the top of the feed hopper 1. The clinker discharged from the guide plate 2 is divided into two by the dividing plate 4. During normal production, it is consistent with the downward discharge method of the existing technology. When the grinding speed is greater than the conveying speed, the clinker is directly shot into the grinding roller. At this time, the servo motor drives the rotating shaft 7 to rotate. The rotating shaft 7 drives the bidirectional cam 6 to rotate 90°. The bidirectional cam 6 drives the two guide plates 5 to rotate around the upper hinge shaft. The two guide plates 5 are simultaneously lifted by the bidirectional cam 6, guiding the clinker to the inner wall of the feed hopper 1 on both sides. By diverting the clinker, the impact wear on the inner wall of the feed hopper 1 is greatly reduced, and the service life of the feed hopper 1 is extended.

[0022] Two guide plates 5 have a rotating shaft groove 8 and a cam groove 9 on their opposite sides. The bidirectional cam 6 is located in the cam groove 9, and the rotating shaft 7 is located in the rotating shaft groove 8.

[0023] The bidirectional cam 6 and the rotating shaft 7 are accommodated in corresponding slots, so that the opposite surfaces of the two guide plates 5 can fit together, reducing the space occupied by the bidirectional cam 6.

[0024] The upper end of the material distribution plate 4 is provided with a symmetrical beveled chamfer 10.

[0025] This prevents clinker from accumulating on the upper part of the distribution plate 4.

[0026] The lower side wall of the feed hopper 1 is connected to two symmetrically arranged roller receiving cylinders 11. The side wall of the roller receiving cylinder 11 is rotatably connected to a roller shaft 12. A roller 13 is connected to the roller shaft 12 inside the roller receiving cylinder 11. The roller 13 is in contact with the inner wall of the roller receiving cylinder 11. When the guide plate 5 is lifted, it can guide the clinker to be directly injected into the roller 13.

[0027] The guide plate 5 guides the cement clinker to the rotating roller 13. The power is transmitted through the rotating roller shaft 12 to drive the rotating roller 13 to rotate. The rotating roller 13 rotates and continuously changes the impact point, which avoids the inner wall of the feed hopper 1 from being impacted, while extending the service life of the rotating roller 13. Moreover, the replacement of the rotating roller is more convenient than the replacement of the feed hopper.

[0028] The bidirectional cam 6 is magnetic, and the guide plate 5 is made of ferromagnetic metal.

[0029] The magnetic connection prevents the guide plate 5 from shaking during material feeding, thus avoiding interference with the feeding process.
