Description

Technical Field

[0001] The utility model relates to the technical field of coal sample weighing and detection, in particular to a coal sample detection auxiliary device. Background Art

[0002] Coal analysis is the process of analyzing the physical and chemical properties of coal samples. As an important energy resource, the quality and properties of coal have a significant impact on combustion efficiency, environmental pollution, etc. Therefore, it is necessary to conduct a detailed analysis of coal. In coal analysis, the sample needs to be weighed and tested. The surrounding environment during the weighing and testing process, as well as the timeliness of the sample analysis are crucial.

[0003] In the prior art, when coal is weighed and tested, the sample bottles containing the coal samples are directly sorted and placed side by side. Each sample completes a routine (moisture, ash, volatile matter, total sulfur, calorific value) test and elemental analysis test, which requires at least 6 times of picking and placing. The high-frequency picking and placing method can easily cause the samples to be scattered and the sample bottles to be placed in the wrong order, which in turn causes distortion of the test data, poses quality risks, and affects the test efficiency. In the process of coal weighing and testing, there are strict requirements on the surrounding temperature and humidity, but the thermometer and hygrometer in the prior art are all set at a fixed position in the sample weighing room and are set in a single manner. It is not easy to detect when the temperature and humidity around the sample changes. The change in temperature and humidity can easily affect the properties of the coal sample itself and thus affect the accuracy of coal weighing and testing. At the same time, in the prior art, the sample bottles will be manually marked before and after the weighing of each test item to distinguish whether the weighing of different test items has been completed, but when the sample volume is large and busy, marking each sample bottle can easily lead to repeated marking or missed marking, resulting in repeated weighing and testing of samples or missed weighing and testing.

[0036] like Figure 1-Figure 4As shown, the present application provides a coal sample detection auxiliary device, which is provided with a body 1, an identification button assembly and a thermometer and hygrometer 5. The body 1 is provided with a plurality of sample bottle placement positions 11, and the sample bottle placement positions 11 are used to place sample bottles containing coal samples. Specifically, the sample bottle placement position 11 is a placement hole, and the bottom diameter of the placement hole is 70 mm, which is convenient for inserting and placing the sample bottle. At the same time, the sample bottle placement position 11 abuts and limits the sample bottle to ensure the stability of the sample bottle placement. Preferably, the sample bottle is a 250 ml sample bottle for holding a 0.2 mm coal sample. Each sample bottle placement position 11 corresponds to an identification button assembly, and the identification button assembly is used to identify the state of the detection item of the sample in the sample bottle placed in each sample bottle placement position 11. The thermometer and hygrometer 5 is provided on the body 1, and the thermometer and hygrometer 5 is used to detect the temperature and humidity of the surrounding environment. Specifically, the thermometer and hygrometer 5 can detect the temperature and humidity in the environment around the sample bottle in real time. Since it is set on the machine body and is close to the sample bottle, it can better control the temperature and humidity of the sample in the sample bottle, so that the sample can be weighed and tested when the temperature and humidity displayed by the thermometer and hygrometer 5 are suitable for the weighing and testing environment, thereby preventing the properties of the coal sample from being changed due to inappropriate temperature and humidity, thereby affecting the accuracy of the coal sample weighing and testing. Furthermore, an arc-shaped protrusion is provided at the bottom end of the placement hole, which is close to the peripheral wall of the sample bottle, for better limiting the sample bottle. The arc-shaped protrusion abuts and limits the outer side of the sample bottle to ensure the stability of the sample bottle placement.

[0037] like Figure 1 As shown, in this embodiment, the coal sample detection auxiliary device also includes a weighing component, and each sample bottle placement position 11 is correspondingly provided with a weighing component, and the weighing component includes a weighing device 21 and a weighing display screen 22. The weighing device is arranged at the bottom of the sample bottle placement position 11, and is used to weigh the weight of the sample bottle placed in the sample bottle placement position 11. The weighing display screen is arranged on the side of the body, and the weighing device is connected to the weighing display screen for communication. Specifically, the weighing device 21 weighs and obtains the weight information data of the sample bottle, and the controller processes the data and transmits the processed data to the weighing display screen 22 for display, so that the inspector can directly observe whether the coal sample retained in the sample bottle meets the weighing requirements of the next time (or the remaining test items). Furthermore, the information obtained by the weighing device 21 is the total weight of the sample bottle and the sample, and the weight of the coal sample remaining in the sample bottle can be obtained when the weight of the sample bottle itself is known.

[0038] In this embodiment, the identification button assembly is arranged on the side of the body 1, and the identification button assembly includes a plurality of identification buttons 3 and a plurality of signal lights, and the plurality of identification buttons 3 and the plurality of signal lights are arranged in a one-to-one correspondence. Each identification button 3 corresponds to a detection item, and the identification button 3 is used to control the switch of the signal light. Specifically, in this embodiment, the identification button 3 and the signal light are combined to form a backlight identification button. When the coal sample in the sample bottle completes a weighing test, the backlight identification button corresponding to the weighing test item in the identification button assembly corresponding to the sample bottle placement position 11 where the sample bottle is located is pressed to change its light state, which can remind the inspector whether the test is completed, avoid repeated weighing or missing weighing of the sample, and play a role in process control. Furthermore, the initial state of the signal light controlled by the identification button 3 is off, and after the identification button 3 is pressed, the signal light controlled by the identification button 3 becomes lit.

[0039] In this embodiment, the coal sample detection auxiliary device also includes a power switch 4, which is arranged on the side of the body 1. The power switch 4 is used to control the power-on state of the thermometer and hygrometer 5, the identification button assembly and the weighing assembly. Specifically, the power switch 4 can control the power-on state of the thermometer and hygrometer 5, the identification button assembly and the weighing assembly with one click. When the coal sample detection auxiliary device is not in use, one click can be used to turn off the power to save energy. When the coal sample detection auxiliary device is to be used, one click can also be used to put the thermometer and hygrometer 5, the identification button assembly and the weighing assembly into working state, which is convenient and quick.

[0040] Furthermore, the body 1 in this embodiment includes a cavity, and the thermometer and hygrometer 5, the identification button assembly, and the weighing assembly are connected to the power supply through a power supply line, and the power supply line is arranged in the cavity of the body 1. Specifically, the power switch 4 controls the power-on state of the thermometer and hygrometer 5, the identification button assembly, and the weighing assembly by changing the on-off state of the power supply line. The power supply line is arranged in the cavity to reasonably use the space, while avoiding unsafe electricity use caused by the exposure of the power supply line.

[0041] like Figure 2-Figure 4As shown, the body 1 in this embodiment is in the shape of a rectangular parallelepiped, and a plurality of sample bottle placement positions 11 are evenly spaced along the length direction of the body 1. Setting the body 1 in the shape of a rectangular parallelepiped also facilitates arranging a plurality of coal sample detection auxiliary devices in a row along the length direction or in a row along the width direction, so that the inspector can control multiple groups of coal samples easily, which helps to increase the number of samples weighed and tested by the inspector and improve the weighing and testing speed of the inspector. Specifically, the body 1 is 360 mm long, 100 mm wide, and 100 mm high, and the shortest distance between the sample bottle placement positions 11 at both ends and the short side of the body 1 is 25 mm. Specifically, there are four sample bottle placement positions 11, and the center distance between the bottom centers of the four sample bottle placement positions 11 is 80 mm. The thickness of the groove wall between two adjacent sample bottle placement positions 11 is 10 mm, so there are also four weighing devices 21, which are respectively arranged at the bottom of the groove of each sample bottle placement position 11. Of course, in other embodiments, the body 1 may also be configured to be a circular shape or other shapes, and a plurality of sample bottle placement positions 11 are arranged at intervals along the circumference of the circular body 1 .

[0042] In this embodiment, the body 1 is further provided with a thermometer and hygrometer installation groove 12, which is arranged at the center of the plurality of sample bottle placement positions 11, and the thermometer and hygrometer 5 is arranged in the thermometer and hygrometer installation groove 12. Specifically, the thermometer and hygrometer installation groove 12 is arranged at the center of the four sample bottle placement positions 11; the thermometer and hygrometer installation groove is a mounting hole, and the bottom diameter of the mounting hole is 9 mm, which is less than the groove wall thickness of 10 mm between two adjacent sample bottle placement positions 11, so it can be arranged in the groove wall between two adjacent sample bottle placement positions 11 in the middle.

[0043] like Figure 4 As shown, the weighing display screen 22 and the identification button 3 in this embodiment are arranged on the same long side of the body 1. Specifically, the weighing display screen 22 is located above the long side, and the identification button 3 is arranged below the long side, so that the inspector can simultaneously observe the weight information of the sample in the sample bottle and the test items that have been carried out. Specifically, since the weighing display screen 22 is arranged corresponding to the weighing device 21, and the weighing device 21 is arranged corresponding to the sample bottle placement position 11, the weighing display screen 22 is also provided with four, and the four weighing display screens are evenly distributed along the length direction of the body 1 on the side where they are located, so that the inspector can observe them. The power switch 4 is arranged on one side of the long side where the weighing display screen 22 is located above the short side of the body 1, so as to facilitate the inspector to control the power supply toward the long side where the weighing display screen 22 is arranged. Specifically, the power switch 4 is rectangular, with a length of 32.77 mm and a width of 11.94 mm. At the same time, since the weighing display screen 22 only needs to display weight data, the liquid crystal display screen, the electronic paper screen, etc. can achieve this effect, and no more restrictions are made on the specific model of the weighing display screen 22.

[0044] like Figure 2-Figure 4 As shown, in this embodiment, support members 6 are provided at the four corners of the bottom of the body 1. Specifically, the support members 6 can be of conventional shapes such as cylindrical or rectangular. The support members 6 can be provided to raise the height of the body 1, so that the inspector can grasp the bottom of the body 1 and the operator can take and put the coal sample detection auxiliary device; at the same time, the support members 6 can also improve the overall stability of the coal sample detection auxiliary device. Furthermore, the support member 6 is a cylindrical structure with a diameter of 8 mm. The distance between the center of the two support members 6 close to the long side of the weighing display screen 22 and the long side is 22 mm; the distance between the center of the two support members 6 close to the long side without the weighing display screen 22 and the long side is 20 mm.

[0045] Specifically, the identification button assembly in this embodiment includes at least two of a moisture identification button, an ash identification button, a volatile matter identification button, a calorific value identification button, a total sulfur identification button, and an element weighing identification button. Specifically, each time a weighing test of a coal sample in a sample bottle is completed, the corresponding identification button in the identification button assembly corresponding to the sample bottle placement position 11 where the sample bottle is located is pressed to indicate that the coal sample in the sample bottle in this sample bottle placement position 11 has completed the weighing test. Therefore, each sample bottle placement position 11 has six corresponding identification buttons 3, and the six identification buttons 3 are distributed in two rows and three columns. A single identification button 3 is a circle with a diameter of 5 mm, and each identification button 3 is marked with text or symbols corresponding to the test item.

[0046] Specifically, the body 1 in this embodiment is made of acrylic plate. The body 1 made of acrylic plate can reduce the overall weight of the coal sample detection auxiliary device, and at the same time can prevent the detection personnel from getting electric shock due to touching the shell, thereby improving safety during use.

[0047] The specific use process of the coal sample detection auxiliary device in this embodiment is as follows: place the sample bottle containing the coal sample in the sample bottle placement position 11, and then turn on the power switch 4. The device will display the weight, temperature and humidity of each sample, and the test weighing and detection status of each test in real time (the indicator light corresponding to the identification button 3 is off at this time). After the inspector A weighs the corresponding test item, he presses the corresponding button (the indicator light corresponding to the identification button 3 is on at this time). After a group of samples are all weighed, other inspectors can take the group of samples that are idle in the coal sample detection auxiliary device of inspector A to weigh other items. After weighing, other inspectors press the corresponding test item. After a group of samples are all weighed, other inspectors return the coal sample detection auxiliary device to the position where inspector A placed it. Through this structural design and its application in coal sample weighing and detection, it is easy to operate when weighing coal samples, simple and convenient, protects samples, prevents affecting detection accuracy, and makes the detection sequence clearer, improves the detection process, saves detection costs, reduces detection risks, and improves detection efficiency. Preferably, the coal sample with a specification of 0.2 mm is weighed and tested. At the same time, the sample bottle is placed in the coal sample detection auxiliary device in this embodiment, so that when the coal sample is weighed and tested, the coal sample detection auxiliary device can be directly taken and placed. For example, 20 samples are tested in the same batch, and a conventional (water content, ash content, volatile matter, total sulfur, calorific value) test and element analysis test are completed, which only requires 30 times of taking and placing. When the coal sample detection auxiliary device is not used, each sample bottle where the 20 samples are located needs to be taken and placed 6 times, that is, a total of 120 times of taking and placing of the sample bottle. The use of the coal sample detection auxiliary device improves the efficiency of the test, and the sample bottle placement positions 11 arranged in sequence can also support the sample bottle to limit it, making the sample bottle easy to take and place and difficult to confuse.

Parts and consumables that are not available on the market can be customized according to the instructions and the drawings. The specific connection methods of various parts and consumables adopt conventional means such as mature bolts and high-strength glue in the prior art.

[0049] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention.
