Description
Technical Field
[0001] This utility model relates to the field of fly ash detection technology, specifically to a fly ash detection and sampling device. Background Technology
[0002] Fly ash is a byproduct of coal combustion, a volcanic ash-like mixture formed after pulverized coal is burned at high temperatures. It is produced in coal-fired power plants by grinding coal into fine particles smaller than 100 micrometers, injecting preheated air into the furnace, and burning it to form a suspension. This produces high-temperature flue gas mixed with a large amount of non-combustible materials. The driven particles in this flue gas are discharged from the coal-fired boiler along with the flue gas, solidifying while suspended in the exhaust gas and collected by electrostatic precipitators or filter bags. Fly ash is a byproduct of thermal power plants and is widely used in the building materials, cement, and concrete industries. To ensure its quality meets national and industry standards and to guarantee the quality and safety of related projects, it must be rigorously tested.
[0003] In the process of fly ash testing, it is essential to sample the fly ash. A utility model patent with application number 202021213138.7 discloses a fly ash sampler for waterproof membrane production. Its method of use involves inserting the sampler into the fly ash to collect samples. However, if multiple samples are to be taken at different depths, this sampler needs to be inserted into the fly ash repeatedly, and the process becomes increasingly laborious with increasing insertion depth, affecting sampling efficiency. Therefore, we have proposed a fly ash testing and sampling device to solve the aforementioned problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-8 This utility model provides a technical solution: a fly ash detection and sampling device, including an outer sampling chamber 1, a conical head 2 fixedly installed at the lower end of the outer sampling chamber 1, a disassembly cylinder 3 installed at the upper end of the outer sampling chamber 1, a handle cylinder 4 installed at the upper end of the disassembly cylinder 3, and a first handle 5 fixedly installed at the end of the handle cylinder 4.
[0026] Furthermore, the conical head 2 is integrated with the external sampling chamber 1, and the lower end of the conical head 2 is hemispherical, which not only facilitates the insertion of the external sampling chamber 1 into the fly ash through the conical head 2, but also ensures the safety of the conical head 2 during use.
[0027] Furthermore, the external sampling chamber 1 and the disassembly cylinder 3, as well as the disassembly cylinder 3 and the handle cylinder 4, are all threaded connections, which facilitates quick assembly and disassembly of the external sampling chamber 1, the disassembly cylinder 3, and the handle cylinder 4. It also allows for changes in the working length of the device, making it suitable for sampling at different depths and increasing the functionality of the device.
[0028] The handle 4 is equipped with a handle rod 7, a second handle 6 is fixed to the end of the handle rod 7, a disassembly rod 8 is connected to the lower end of the handle rod 7, a sampling rod 9 is connected to the lower end of the disassembly rod 8, and disassembly components for quick disassembly and assembly are provided between the handle rod 7 and the disassembly rod 8 and between the disassembly rod 8 and the sampling rod 9.
[0029] Furthermore, the disassembly assembly includes a connecting rod sleeve 11, a button 12, a first spring 13, a locking block 14, and a second spring 15. The connecting rod sleeve 11 is integrally set at the upper end of the disassembly rod 8 and the sampling rod 9. The connecting rod sleeve 11 is sleeved with both the handle rod 7 and the disassembly rod 8 to ensure the stable connection of the connecting rod sleeve 11. The lower ends of the handle rod 7 and the disassembly rod 8 are both equipped with locking blocks 14 and second springs 15. The locking blocks 14 can move back and forth through the second springs 15. The locking blocks 14 are embedded in the connecting rod sleeve 11. The connecting rod sleeve 11 is equipped with a button 12 and a first spring 13. The button 12 is aligned with the locking blocks 14. The button 12 can squeeze the locking blocks 14 to retract into the handle rod 7 or the disassembly rod 8 and hide them, so that the disassembly work can be completed quickly.
[0030] The lower end of the sampling rod 9 is fixed with an inner sampling cavity 10, which is located inside the outer sampling cavity 1.
[0031] Furthermore, the handle 7, disassembly rod 8, sampling rod 9, and inner sampling cavity 10 are inserted into the outer sampling cavity 1, disassembly cylinder 3, and handle cylinder 4. The outer diameter of the inner sampling cavity 10 and the connecting rod sleeve 11 is equal to the inner diameter of the outer sampling cavity 1, disassembly cylinder 3, and handle cylinder 4, ensuring that the inner sampling cavity 10 slides stably back and forth within the outer sampling cavity 1.
[0032] Furthermore, the outer sampling cavity 1 has an opening, and the width of the opening is smaller than the inner diameter of the outer sampling cavity 1. The inner sampling cavity 10 has an opening with the same size as the opening on the outer sampling cavity 1. The inner sampling cavity 10 is a rotatable structure inside the outer sampling cavity 1, which facilitates the entry of fly ash into the inner sampling cavity 10 and also ensures that the inner sampling cavity 10 can rotate stably inside the outer sampling cavity 1.
[0033] Furthermore, the lower end of the inner sampling chamber 10 is inclined to facilitate the removal of fly ash from the outer sampling chamber 1 when the inner sampling chamber 10 moves downward. The inner sampling chamber 10 and the connecting rod sleeve 11 are both provided with planar structures on their sides, so that there are gaps between the inner sampling chamber 10 and the outer sampling chamber 1, the disassembly cylinder 3 and the handle cylinder 4, which makes it easier for the inner sampling chamber 10 to move.
[0034] Working principle: When using this fly ash detection and sampling device, firstly, based on the sampling depth in the fly ash pile, assemble an appropriate length of outer sampling chamber 1, disassembly cylinder 3 and handle cylinder 4, connect an appropriate number of disassembly cylinders 3 to the outer sampling chamber 1 by threaded connection, and finally install the handle cylinder 4.
[0035] Then, based on the working length of the external sampling chamber 1 after assembly, the handle rod 7, disassembly rod 8, and sampling rod 9 are assembled. The lower end of the disassembly rod 8 is inserted into the connecting rod sleeve 11 on the sampling rod 9. The locking block 14 is stably embedded in the connecting rod sleeve 11 under the action of the second spring 15 to ensure the stable connection state of the disassembly rod 8. Then, according to the required length, the number of disassembly rods 8 to be installed is selected. The disassembly rods 8 are also fixedly connected to each other through the connecting rod sleeve 11. Finally, the handle rod 7 is installed on the disassembly rod 8. At the same time, it is necessary to ensure that the length of the handle rod 7, disassembly rod 8, and sampling rod 9 is greater than the length of the external sampling chamber 1, disassembly cylinder 3, and handle cylinder 4 to ensure that the subsequent sampling work can proceed normally.
[0036] After the handle 7, disassembly rod 8 and sampling rod 9 are assembled, the inner sampling chamber 10 is inserted into the outer sampling chamber 1, disassembly cylinder 3 and handle cylinder 4, so that the inner sampling chamber 10 is stably located in the outer sampling chamber 1. Then, the operator holds the first handle 5 on the handle cylinder 4 and inserts the entire device into the fly ash pile to the required sampling depth. Before insertion, the inner sampling chamber 10 must be rotated to the state of blocking the opening on the outer sampling chamber 1.
[0037] During the insertion process, the conical head 2 can be inserted quickly and easily. When a specific depth is reached, the second handle 6 is rotated, and the inner sampling chamber 10 is rotated in conjunction with the handle rod 7, the disassembly rod 8, and the sampling rod 9, so that the upper opening of the inner sampling chamber 10 coincides with the upper opening of the outer sampling chamber 1. In this way, the fly ash at the corresponding depth position will enter the inner sampling chamber 10. Then, the inner sampling chamber 10 is pulled out directly to complete the sampling work.
[0038] Then, the sampler continues to penetrate deeper into the outer sampling chamber 1 to sample fly ash at a deeper location. After the sample is taken out from the inner sampling chamber 10, it can quickly reach a specific depth through the outer sampling chamber 1, disassembly cylinder 3, and handle cylinder 4. During this process, it is necessary to ensure that the upper opening of the inner sampling chamber 10 faces the inside of the outer sampling chamber 1. The inclined surface at the lower end of the inner sampling chamber 10 can dissipate the fly ash in the outer sampling chamber 1. Furthermore, the planar arrangement of the inner sampling chamber 10 and the side of the connecting rod sleeve 11 can effectively allow for ventilation. Therefore, the inner sampling chamber 10 can be easily inserted into the outer sampling chamber 1 for further sampling.
[0039] By increasing the insertion depth of the outer sampling cavity 1 in sequence, sampling at different depths can be completed quickly through the inner sampling cavity 10, ensuring the convenience and efficiency of the sampling work.
[0040] The above describes the usage process of the device. Any content not described in detail in this specification is existing technology known to those skilled in the art.
[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
