Description

Technical Field

[0001] This utility model relates to the technical field of grinding sound analyzers, specifically a grinding sound analyzer. Background Technology

[0002] The grinding sound analyzer collects the sound or vibration signals generated by the collision of steel balls and materials inside the ball mill. Combined with spectrum analysis technology, it quantitatively assesses the mill load status (such as material filling amount and the ratio of grinding media to materials) and outputs control signals (such as 4-20mA current) to adjust the raw material flow rate, thereby achieving the goals of energy saving, consumption reduction, and stable production.

[0003] Existing grinding sound analyzers include a grinding sound probe and a main unit. The two transmit signals through a shielded cable. When installing, the grinding sound probe is generally installed in the lower half of the ball mill cylinder (at the 4 o'clock position) by a bracket. The main unit is located in the central control room and is connected to the DCS system through a 4-20mA current signal.

[0004] As can be seen from the above, existing grinding sound analyzers have the following drawbacks in use: When maintenance or other operations are required on the ball mill cylinder, the grinding sound probe usually needs to be removed first to avoid interference or damage during the maintenance process. However, if the grinding sound probe is directly removed, its position needs to be readjusted during subsequent reinstallation, which not only increases the workload but also affects the convenience of operation. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a grinding sound analyzer that makes the storage of grinding sound probes more convenient.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a grinding sound analyzer, comprising a grinding sound probe, a universal adjustment rod connected to the bottom of the grinding sound probe, and a main unit connected to one side of the grinding sound probe. The bottom of the universal adjustment rod is connected to a telescopic storage structure, which includes a first rod, a second rod, and a third rod. The second rod is slidably connected to the inner side wall of the top of the first rod, and the third rod is slidably connected to the inner side of the top of the second rod. The top of the third rod is fixedly installed to the bottom of the universal adjustment rod. The first rod, the second rod, and the third rod are all rectangular rods. The outer walls of the first rod and the second rod are connected to a pressing member for limiting the second rod and the third rod.

[0007] Furthermore, the extrusion member includes a first extrusion rod and a second extrusion rod. The first extrusion rod is threadedly connected to a first rod, and one end of the first extrusion rod passes through the first rod and abuts against the outer wall of the second rod. The second extrusion rod is threadedly connected to the second rod, and one end of the second extrusion rod passes through the second rod and abuts against the outer wall of the third rod.

[0008] Furthermore, the outer ends of both the first extrusion rod and the second extrusion rod are fixedly connected with anti-slip rotating bosses.

[0009] Furthermore, a base plate is connected to the outer wall of the first rod, and a protective cover for housing the grinding sound probe is fixedly connected to the top surface of the base plate.

[0010] Furthermore, the protective cover is a bellows cover.

[0011] Furthermore, a top cover is hinged to one side of the top of the protective cover.

[0012] Furthermore, a wire groove is provided on the top of the top cover.

[0013] Furthermore, a weight-reducing groove is provided inside the third rod.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention optimizes the original round rod support into a rectangular first rod, second rod, and third rod, so that the first rod, second rod, and third rod only need to be raised and lowered without adjusting the angle of the grinding probe. Moreover, the height of the retracted support will not obstruct the maintenance of the ball mill cylinder. The structure is simple, easy to operate, and highly practical. Attached Figure Description

[0021] 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.

[0022] like Figures 1 to 4As shown, a grinding sound analyzer includes a grinding sound probe 1, a universal adjustment rod 3 connected to the bottom of the grinding sound probe 1, and a main unit 2 connected to one side of the grinding sound probe 1. The bottom of the universal adjustment rod 3 is connected to a telescopic storage structure, which includes a first rod 4, a second rod 5, and a third rod 6. The second rod 5 is slidably connected to the inner side wall of the top of the first rod 4, and the third rod 6 is slidably connected to the inner side of the top of the second rod 5. The top of the third rod 6 is fixedly installed to the bottom of the universal adjustment rod 3. The first rod 4, the second rod 5, and the third rod 6 are all rectangular rods. The outer walls of the first rod 4 and the second rod 5 are connected to a pressing member for limiting the second rod 5 and the third rod 6.

[0023] like Figures 1 to 4 As shown, when the grinding sound analyzer of this utility model is in use and maintenance of the ball mill is required, the extrusion part can be opened, so that the first rod 4, the second rod 5 and the third rod 6 retract in stages, so that the second rod 5 slides into the first rod 4 and the third rod 6 slides into the second rod 5. This reduces the height of the grinding sound probe 1 and avoids the grinding sound probe 1 being located at the cylinder wall of the ball mill and causing obstruction.

[0024] Furthermore, since the first rod 4, the second rod 5, and the third rod 6 are all rectangular rods, there is no need to adjust the angle of the grinding sound probe 1 when it is lowered. After the grinding sound probe 1 is raised again, the rectangular rods ensure that the grinding sound probe 1 can only be raised and lowered vertically, so the angle of the grinding sound probe 1 after it is raised does not need to be adjusted again.

[0025] By optimizing the original round rod support into a rectangular arrangement of the first rod 4, the second rod 5, and the third rod 6, the first rod 4, the second rod 5, and the third rod 6 can be raised and lowered without adjusting the angle of the grinding sound probe 1, and the height of the retracted support will not obstruct the maintenance of the ball mill cylinder.

[0026] like Figure 1 and Figure 4 As shown, the extrusion component includes a first extrusion rod 7 and a second extrusion rod 8. The first extrusion rod 7 is threadedly connected to the first rod 4, and one end of the first extrusion rod 7 passes through the first rod 4 and abuts against the outer wall of the second rod 5. The second extrusion rod 8 is threadedly connected to the second rod 5, and one end of the second extrusion rod 8 passes through the second rod 5 and abuts against the outer wall of the third rod 6.

[0027] Specifically, in order to facilitate the limitation of the adjusted height of the second rod 5 and the third rod 6, the first pressing rod 7 can be threadedly connected to the first rod 4, so that the end of the first pressing rod 7 passes through the first rod 4 and abuts against the outer wall of the second rod 5. Through friction, the position of the second rod 5 is limited. Similarly, the position of the third rod 6 can be limited by operating the second pressing rod 8, so that its end is threadedly connected to the second rod 5. After the second pressing rod 8 passes through the second rod 5, its end will abut against the outer wall of the third rod 6, thereby using friction to limit the position of the third rod 6.

[0028] like Figure 1 and Figure 4 As shown, the outer ends of the first extrusion rod 7 and the second extrusion rod 8 are both fixedly connected to anti-slip rotating bosses.

[0029] Specifically, the anti-slip rotating boss makes the rotation operation of the first extrusion rod 7 and the second extrusion rod 8 more convenient.

[0030] like Figure 2 and Figure 3 As shown, the outer wall of the first rod 4 is connected to a base plate 9, and a protective cover 10 for housing the grinding sound probe 1 is fixedly connected to the top surface of the base plate 9.

[0031] Specifically, after the grinding sound probe 1 descends, it can enter the protective cover 10. The protective cover 10 and the base plate 9 can protect the grinding sound probe 1 and prevent minor impacts from damaging it during maintenance.

[0032] like Figure 2 and Figure 3 As shown, the protective cover 10 is a bellows cover. The bellows cover design of the protective cover 10 makes it easy to lower and store the protective cover 10, expose the first pressing rod 7, facilitate the operation of the first pressing rod 7, and reduce the overall area of ​​the protective cover 10 when not in use.

[0033] like Figure 2 and Figure 3 As shown, a top cover 11 is hinged to one side of the top of the protective cover 10. The top cover 11 is provided to further improve the protective effect of the protective cover 10.

[0034] It should be noted that the top of the protective cover 10 and the bottom of the top cover 11 are magnetically connected by magnetic plates and iron plates, ensuring that the top cover 11 will not be easily opened by the pulling force of the protective cover 10 (i.e., the accordion cover).

[0035] like Figure 2 and Figure 3 As shown, a wire groove 12 is provided on the top of the top cover 11. The wire groove 12 is provided to facilitate the exposure of the data cable of the grinding sound probe 1.

[0036] like Figure 4 As shown, a weight-reducing groove 13 is provided inside the third rod 6. The weight-reducing groove 13 reduces the weight of the third rod 6, making it easier to carry and transport.

[0037] 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.
