Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of auxiliary devices for calcium carbide production, specifically to a sampling device for a belt conveyor. Background Technology
[0002] Lime is one of the key raw materials for the production of calcium carbide. Specifically, the production of calcium carbide mainly relies on limestone (whose main component is calcium carbonate, which decomposes into calcium oxide, i.e., quicklime, after heating) and coke or semi-coke. In the calcium carbide furnace, lime (existing in the form of calcium oxide) is smelted together with coke or semi-coke at high temperatures. The electrical energy between the electrodes generates resistance, and the heat energy converted from the electric arc heats the materials, causing a chemical reaction to produce calcium carbide.
[0003] Lime, a raw material for calcium carbide, needs to be sampled before it can be processed into calcium carbide. The purpose of sampling is mainly to ensure the quality and representativeness of the lime, so as to obtain a stable and high-quality product in the subsequent calcium carbide production process. In the calcium carbide production process, a belt conveyor is generally used to continuously transport lime to the next stage of processing equipment. During the transportation process, lime on the belt conveyor needs to be sampled. However, for safety reasons, the belt conveyor needs to be stopped for sampling. The simplest and most direct method is manual sampling, that is, the operator uses a shovel or other tools to shovel the lime off the belt conveyor and put it into a sampling container.
[0004] However, pausing the belt conveyor for manual sampling affects overall work efficiency and slows down the work progress. Therefore, there is an urgent need for a device that can achieve efficient sampling without stopping the belt conveyor, so as to ensure that calcium carbide production maintains high efficiency. Utility Model Content
[0005] The purpose of this invention is to provide a sampling device for belt conveyors to solve the problem of needing to pause the belt conveyor for manual sampling.
[0006] To achieve the above objectives, the basic solution provided by this utility model is as follows: a sampling device for a belt conveyor, comprising a support and a sampler. A geared motor is mounted on the support, and a coupling is mounted on the output shaft of the geared motor. One end of the coupling is a rotating shaft, which is fixedly connected to the support. A bearing seat is mounted on the support, and the rotating shaft is rotatably connected to the bearing seat. The sampler is fixedly connected to the rotating shaft. The sampler is located directly above the belt conveyor, and the belt conveyor is located directly below the support. A chute is mounted on the support, and the chute is located below the material output end of the sampler.
[0007] The principle and beneficial effects of this invention are as follows: By placing a sampler directly above the belt conveyor, and driving it to rotate in place around a rotating shaft by a geared motor, the sampler contacts the material on the belt conveyor when it rotates to a position close to the belt conveyor, and uses the force of rotation to throw the material into the chute. This operation allows for sampling using a rotating sampler without stopping the belt conveyor.
[0008] Option 2, a preferred option of the basic scheme, features two baffles on the support frame. These baffles are fixed to both sides of the chute and positioned below the sampler's output end, near the belt conveyor. To avoid interfering with the belt conveyor's normal operation, a gap exists between the frame and the conveyor. During sampling, the sampler's rotation causes some material to be thrown out of the chute's range, resulting in waste. The baffles effectively collect this thrown-out material, preventing waste.
[0009] Option 3, an optimal choice from the basic option, involves bolting a cover to the support frame. The cover is positioned directly above the support frame and covers the chute and sampler. The cover completely encloses the sampler and chute, preventing operators from being accidentally injured by material ejected from the sampler and enhancing the safety of the sampling operation.
[0010] Option 4, a preferred option of Option 3, features an observation window on the housing. This window allows operators to easily monitor the sampling process of the sampler inside the housing.
[0011] Option 5, an optimal choice from the basic option, involves a counterweight fixed to the feeding end of the sampler. To enable the sampler to more efficiently throw material from the belt conveyor into the chute, the shaft is not connected to the geometric center of the sampler, but rather to a position near the tail end. By fixing the counterweight to the feeding end, the feeding end of the sampler can obtain a greater degree of centrifugal force, increasing the throwing force and thus enabling the sampler to more efficiently throw material from the belt conveyor into the chute.
[0012] Option 6, an optimal choice from the basic option, features a curved feeding end on the sampler. By arranging the feeding end with a certain curvature, it can achieve maximum contact with the material without damaging the conveyor belt. Attached Figure Description

The sampler 2 is located directly above the belt conveyor 7. A counterweight 12 is welded to the feeding end of the sampler 2. The feeding end of the sampler 2 has an arc. The belt conveyor 7 is located directly below the support 1.
[0021] A chute 8 is welded onto the support 1. The chute 8 is located below the material output end of the sampler 2. Two baffles 9 are welded onto the support 1. The two baffles 9 are welded to both sides of the chute 8 respectively. Both baffles 9 are located below the material output end of the sampler 2. The two baffles 9 are located at one end close to the belt conveyor 7. A cover 10 is bolted onto the support 1. The cover 10 is located directly above the support 1. The cover 10 covers the chute 8 and the sampler 2. An observation window 11 is welded onto the cover 10.
[0022] The implementation method of this embodiment is as follows:
[0023] When sampler 2 needs to take a sample, it first drives geared motor 3. Geared motor 3 drives shaft 5 to rotate through coupling 4. Shaft 5 drives sampler 2 to rotate. Sampler 2 throws the material on belt conveyor 7 into chute 8. The material passes through chute 8 and finally enters the sampling container below chute 8.
