Abstract
Description
Technical Field
[0001] The invention relates to flow detection of metallurgical raw materials (block material, granular material, powdery material) such as iron ore and coal coke during conveyance by a belt, and in particular to a wear-resistant device for detecting the flow of ore on a belt. Background Art
[0002] With the continuous increase of automatic sampling equipment in metallurgical enterprises, in order to ensure the smooth sampling of samples on the belt, it is necessary to rely on the belt flow detection device to detect the material flow on the belt. The flow detection heads of the belt flow detection equipment used in general factories are all made of ordinary carbon steel or wear-resistant steel. Due to the impact of materials such as iron ore and coal coke, the flow detection heads wear quickly and have a short service life, resulting in frequent stopping of the belt to replace the flow detection heads.
[0003] It is easy to cause the following problems: 1. If the flow head is severely worn, the material flow cannot be detected, and the material flow detection equipment cannot transmit the incoming material signal to the automatic sampler, causing the automatic sampler to fail to start due to no material flow signal and miss the sample; 2. The flow detection head needs to be replaced by stopping the belt, and frequent replacement will affect the production progress.
[0004] Therefore, it is necessary to develop a new type of wear-resistant device for detecting the ore flow on the belt to extend the service life of the material flow detection head. Summary of the invention
[0005] Purpose of the invention: In view of the shortcomings and defects of the prior art, the present invention provides a wear-resistant device for detecting the ore flow on the belt, and replaces a belt flow detection head made of wear-resistant ceramic material to achieve the goals of reducing the wear rate of the flow detection head, extending its service life, reducing the frequency of replacement, and saving costs.
[0006] Technical solution: The present invention is a wear-resistant device for detecting the flow of ore on a belt, characterized in that a 400mm*100mm*100mm wear-resistant ceramic detection head is drilled and fixed at the contact position between the belt flow detection equipment and the material to detect the flow of the transported material on the main belt. The flow of the transported material on the main belt is transmitted to the automatic sampling equipment through the material flow detection equipment, and the automatic sampling equipment determines whether to start sampling through the incoming material signal.
[0007] Wherein, after the wear-resistant ceramic detection head is drilled, it is connected to the belt flow detection equipment through a bolt passing through the hole body.
[0008] Wherein, a swing arm is provided on the side of the wear-resistant ceramic detection head.
[0009] Wherein, the swing arm corresponds to the proximity switch on its side.
[0010] Wherein, the belt flow detection device is located between the side pillars of the gantry.
[0011] Wherein, the main belt is located between the side pillars of the gantry and is also located below the wear-resistant ceramic detection head.
[0012] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: The present invention solves the problems of fast wear speed, short service life and frequent replacement of the material flow detection head by replacing a material flow detection head made of wear-resistant ceramic material. It is suitable for material flow detection equipment for block materials, granular materials, powder materials and other materials transported by belts at the production site of metallurgical enterprises. After the material of the material flow detection head is changed from wear-resistant steel to wear-resistant ceramic material, the replacement frequency caused by wear will be significantly reduced, the service life will be increased, and direct economic benefits will be generated. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] Figure 1 It is a structural schematic diagram of the present invention;
[0014] In the figure, 1 is the gantry; 2 is the proximity switch; 3 is the swing arm; 4 is the wear-resistant ceramic detection head; and 5 is the main belt. DETAILED DESCRIPTION
[0015] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.
[0016] The wear-resistant device for detecting the ore flow on the belt of the present invention drills a 400mm*100mm*100mm wear-resistant ceramic detection head 4 and fixes it at the contact position between the belt flow detection equipment and the material to detect the flow of the transported material on the main belt 5. The flow of the transported material on the main belt 5 is transmitted to the automatic sampling equipment through the material flow detection equipment, and the automatic sampling equipment determines whether to start sampling through the incoming material signal.
[0017] Among them, after the wear-resistant ceramic detection head 4 is drilled, it is connected to the belt flow detection device by a bolt passing through the hole body. A swing arm 3 is provided on the side of the wear-resistant ceramic detection head 4. The swing arm 3 corresponds to the proximity switch 2 on its side. The belt flow detection device is located between the side pillars of the gantry 1. The main belt 5 is located between the side pillars of the gantry 1 and is also located below the wear-resistant ceramic detection head 4.
[0018] The present invention controls the wear rate, replacement frequency and cost of the flow detection head by replacing the material of the flow detection head. The present invention uses wear-resistant ceramics as the flow detection head at the contact point between the flow detection device and the material, and fixes it on the flow detection device with screws after manual drilling. The wear rate of the flow detection head is reduced by the wear resistance of the wear-resistant ceramics, avoiding the automatic sampler from failing to start and missing samples due to excessive wear, and achieving the goal of controlling its replacement frequency, reducing the adverse effects on production caused by replacing the flow detection head, and saving costs.
[0019] After testing, it was found that the replacement frequency of the material flow detection head due to wear was significantly reduced from the original 3 days / time to the current 180 days / time. The wear-resistant steel belt material flow detection head is about 80 yuan / piece, and the wear-resistant ceramic belt material flow detection head is about 340 yuan / piece, so the economic benefit generated is 9,000 yuan / year.
