Abstract
Description
Technical Field
[0001] This utility model relates to the field of elastic modulus technology, and in particular to a device for measuring the elastic modulus of biomass pellet fuel. Background Technology
[0002] The elastic modulus measuring device for biomass pellet fuel is used to measure the ability of biomass pellets to deform after an external force is applied, thereby determining their elastic modulus (also known as Young's modulus). As a renewable energy material, the mechanical properties of biomass pellet fuel (such as wood pellets, straw pellets, etc.) have an important impact on combustion efficiency, transportation, and storage.
[0003] However, when using smaller measuring devices for elasticity testing, the excessive amount of material placed inside the device can lead to excessive amplitude during measurement, resulting in inaccurate data.
[0004] To address the above problems, we propose a device for measuring the elastic modulus of biomass pellet fuel. Utility Model Content
[0005] The purpose of this invention is to solve the problems in the background art by proposing a device for measuring the elastic modulus of biomass pellet fuel.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a device for measuring the elastic modulus of biomass pellet fuel, comprising a placement plate, a displacement sensing plate on the top of the placement plate, a measuring device body fixedly connected to the top of the displacement sensing plate, a force sensor fixedly disposed at the bottom of the measuring device body, a placement ring placed on the outer side of the placement plate, a limiting ring located outside the measuring device body above the placement ring, a plurality of springs fixedly connected to the top of the placement ring, the tops of the plurality of springs being fixedly connected to the bottom of the limiting ring, a plurality of limiting rods fixedly connected to the top of the placement ring, the tops of the plurality of limiting rods being slidably connected to the bottom of the limiting ring.
[0007] In the above-mentioned device for measuring the elastic modulus of biomass pellet fuel, a second spring is fixedly connected to the top of the placement plate, the top of the second spring is fixedly connected to the bottom of the displacement sensing plate, two fixing rods are fixedly connected to the top of the placement plate, and an elastic block is fixedly connected to the top of each of the two fixing rods. The top of the elastic block is fixedly connected to the bottom of the displacement sensing plate.
[0008] In the above-mentioned device for measuring the elastic modulus of biomass pellet fuel, a plurality of springs are evenly arranged on the top of the placement ring, and a plurality of limiting rods are evenly arranged on the top of the placement ring.
[0009] In the above-mentioned device for measuring the elastic modulus of biomass pellet fuel, the second spring is located between two fixed rods, and the two fixed rods are located on the left and right sides of the top of the placement plate.
[0010] In the above-mentioned device for measuring the elastic modulus of biomass pellet fuel, a rotating cover is rotatably provided on the top of the main body of the measuring device.
[0011] In the aforementioned apparatus for measuring the elastic modulus of biomass pellet fuel, the elastic block is made of rubber.
[0012] Compared with existing technologies, the advantages of this biomass pellet fuel elastic modulus measuring device are:
[0013] When the measuring device body of this utility model is being tested, it can be used with other components to speed up and improve the testing speed. However, the measuring device body may tilt or shake too much, causing problems in the test. At this time, the measuring device body will contact the limiting ring, so that the test will not be affected by the excessive amplitude. After the limiting ring contacts, it will be translated by the limiting rod, but will then be pulled back to its original position by the spring, so as to continue to limit and protect the measuring device body during the test.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0019] Reference Figures 1-3A device for determining the elastic modulus of biomass pellet fuel includes a placement plate 1, a displacement sensing plate 2 on the top of the placement plate 1, a measuring device body 3 fixedly connected to the top of the displacement sensing plate 2, a force sensor 9 fixedly installed at the bottom of the measuring device body 3, a placement ring 5 placed on the outer side of the placement plate 1, a limiting ring 6 located outside the measuring device body 3 above the placement ring 5, multiple springs 7 fixedly connected to the top of the placement ring 5, the tops of the multiple springs 7 being fixedly connected to the bottom of the limiting ring 6, multiple limiting rods 8 fixedly connected to the top of the placement ring 5, the tops of the multiple limiting rods 8 being slidably connected to the bottom of the limiting ring 6, multiple springs 7 being evenly distributed on the top of the placement ring 5, multiple limiting rods 8 being evenly distributed on the top of the placement ring 5, and a rotating cover 4 rotatably mounted on the top of the measuring device body 3. When the main body 3 is working, it will generate elastic vibration for testing. At this time, the measuring device main body 3 will vibrate through the displacement sensing plate 2, which will transmit force to the elastic block 11 and the second spring 12. The elastic block 11 and the second spring 12 will vibrate due to the rubber properties and increase the vibration force to improve the detection speed of the measuring device main body 3. The force sensor 9 is used to accurately measure the external force applied to the biomass pellet. The force sensor 9 usually needs to have high precision and a large range to adapt to biomass pellets of different sizes and hardness. The displacement sensing plate 2 is used to measure the deformation (displacement) of the biomass pellet. Commonly used displacement sensors include laser displacement sensors, capacitive displacement sensors, etc. By measuring the deformation of the pellet, the strain can be obtained (the displacement sensing plate 2, force sensor 9, and measuring device main body 3 are all existing technologies and will not be described in detail here).
[0020] A second spring 12 is fixedly connected to the top of the placement plate 1. The top of the second spring 12 is fixedly connected to the bottom of the displacement sensing plate 2. Two fixed rods 10 are fixedly connected to the top of the placement plate 1. An elastic block 11 is fixedly connected to the top of each of the two fixed rods 10. The top of the elastic block 11 is fixedly connected to the bottom of the displacement sensing plate 2. The second spring 12 is located between the two fixed rods 10. The two fixed rods 10 are located on the left and right sides of the top of the placement plate 1. The elastic block 11 is made of rubber. When the measuring device body 3 is being tested, it can speed up the test by cooperating with other components. However, the measuring device body 3 may tilt and shake too much, causing test problems. At this time, the measuring device body 3 will contact the limiting ring 6, so that the test will not be affected by the excessive amplitude. After the limiting ring 6 contacts, it will be translated by the limiting rod 8, but will then be pulled back to its original position by the first spring 7, so as to continue to perform the limiting protection test on the measuring device body 3.
[0021] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.
[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
