Description

Technical Field

[0001] This utility model belongs to the technical field of rod mill equipment and relates to a rod mill disordered rod detection device. Background Technology

[0002] Rod mills are key equipment in rod milling systems for fine material grinding, and their stable operation is crucial. The main function of the steel rods in a rod mill is to crush ore materials through a falling and grinding process, driven by the mill. When the steel rods fall from a height, they generate a large impact force, directly crushing the material. When the material is between the steel rods or between the steel rods and the mill body, it is further crushed by the compression and friction of the steel rods, helping to grind the material to a qualified particle size. When rod entanglement occurs in the rod mill, it is usually impossible to stop the mill immediately, leading to steel rod entanglement inside the mill, making subsequent maintenance difficult and prolonging the repair time. Utility Model Content

[0003] The purpose of this invention is to address the problem in the prior art that the disordered rod phenomenon in rod mills cannot be detected in a timely manner, and to provide a rod mill disordered rod detection device.

[0004] Therefore, the present invention adopts the following technical solution:

[0005] A rod mill disorder detection device includes a rod mill body, a cylinder on the rod mill body, a feed inlet at one end of the cylinder, a bracket on one side of the feed inlet, a rotatable rubber detection rod on the bracket, the rubber detection rod extending into the feed inlet, a lever fixed to the outer end of the rubber detection rod, a proximity switch on one side of the lever, the proximity switch fixed to the bracket, and a controller connected to the proximity switch and the rod mill body.

[0006] Furthermore, the lever is set perpendicular to the rubber detection rod.

[0007] Furthermore, the bracket is provided with a rotating shaft, and the rubber detection rod is fixed on the rotating shaft and can rotate with the rotating shaft.

[0008] Furthermore, the bracket is provided with a support rod, and the outer end of the rubber detection rod abuts against the support rod.

[0009] Furthermore, a limiting rod is provided above the support rod, and the rubber detection rod is located between the support rod and the limiting rod.

[0010] Furthermore, a detection block is provided at the end of the lever away from the rubber detection rod.

[0011] The beneficial effects of this utility model are as follows: a rotatable rubber detection rod is set at the feed inlet of the rod mill cylinder. When the rod disorder occurs, the grinding rod moves to the vicinity of the feed inlet of the cylinder and collides with the rubber detection rod, causing the rubber detection rod to rotate and be detected by the proximity switch. The detection is fast and accurate; the structure is simple, the cost is low, and the use is convenient. Attached Figure Description

[0016] The present invention will now be described in detail with reference to the accompanying drawings:

[0017] like Figure 1-3 As shown, a rod mill disorder detection device includes a rod mill body 1, a cylinder 2 on the rod mill body 1, and a feed inlet 3 at one end of the cylinder 2. The rod mill body 1 is a conventional rod mill body. The rod mill body 1 drives the cylinder 2 to rotate, grinding the material inside the cylinder 2. During use, material and grinding rods are added to the rod mill body 1 through the feed inlet 3. After grinding, the material and grinding rods inside the cylinder 2 are poured out through the feed inlet 3. A bracket 4 is provided on one side of the feed inlet 3, and a rotatable rubber detection rod 5 is provided on the bracket 4. The rubber detection rod 5 is made of rubber rod and has good elasticity. Specifically, a horizontally arranged rotating shaft 6 is provided on the bracket 4, located outside the feed inlet 3, and the rubber detection rod 5 is fixed. The rubber detection rod 5 is mounted on the rotating shaft 6 and can rotate with the rotating shaft 6 in a vertical plane. One end of the rubber detection rod 5 extends into the feed inlet 3. When the rod malfunctions, the magic rod reaches the feed inlet 3 and touches the rubber detection rod 5, causing the rubber detection rod 5 to rotate. A lever 7 is fixed to the outer end of the rubber detection rod 5 and is perpendicular to the rubber detection rod. A proximity switch 8 is provided on one side of the lever 7 and is fixed on the bracket 4. A detection block 9 is provided at the end of the lever 7 away from the rubber detection rod 5. When the rubber detection rod 5 rotates, it can drive the lever 7 to rotate, thereby causing the detection block 9 to be detected by the proximity switch 8. The proximity switch 8 is connected to a controller 10, which is connected to the rod mill body 1. The controller 10 can control the rod mill body 1 to stop running.

[0018] In addition, the lever 7 and the detection block 9 also act as counterweights. Therefore, the bracket 4 is equipped with a support rod 11. The support rod 11 and the rotating shaft 6 are located on the same horizontal plane. The outer end of the rubber detection rod 5 abuts against the support rod 11. With the support of the support rod 11, the rubber detection rod 5 rotates in an inclined state under the gravity of the lever 7 and the detection block 9, and cannot properly extend into the feed port 3 for detection. A limiting rod 12 is provided above the support rod 7. The rubber detection rod 5 is located between the support rod 7 and the limiting rod 12. The limiting rod 12 can limit the rotation angle of the rubber detection rod 5 to prevent the rubber detection rod 5 from rotating too much, causing the detection block 9 to collide with the proximity switch 8 and cause damage.

[0019] The method of using this utility model is as follows:

[0020] When the rod mill is running, if rod misalignment occurs, the grinding rods inside the cylinder 2 move towards the feed inlet 3. When the rubber of the grinding rod collides with the detection rod 5, whether the collision occurs downwards above or upwards below the detection rod 5, the inner end of the detection rod 5 will rotate downwards due to its good elasticity (an upward collision causes the outer end of the detection rod 5 to be squeezed against the support rod 11, and then the inner end of the detection rod 5 rotates downwards under the elastic force). This causes the lever 7 to rotate, bringing the detection block 9 close to the proximity switch 8, which can quickly and timely detect the rod misalignment. The proximity switch 8 sends a signal to the controller 10, and the controller 10 controls the rod mill body 1 to stop running in time for maintenance to prevent accidents.
