Description

Technical Field

[0001] This utility model relates to the technical field of Raymond mills, and in particular to a Raymond mill with shock absorption effect. Background Technology

[0002] The Raymond mill is a high-fineness powder processing machine used in industries such as mining, chemical, and construction. The entire machine has a vertical structure, occupies a small area, and is highly integrated, forming an independent production system from the initial processing of raw materials to conveying, powdering, and final packaging.

[0003] When using a Raymond mill to grind materials, the equipment itself generates vibrations. However, the situation becomes more complex when the material being ground contains hard objects. These hard objects interact with the grinding components inside the mill, significantly increasing the vibration amplitude. Prolonged exposure to this intense vibration will subject various components of the Raymond mill to additional stress and impact. For example, critical components such as the mill's main shaft and bearings may fail prematurely due to excessive wear; connecting bolts may loosen or even break; and cracks may appear in the mill's cylinder. This ultimately affects the overall performance and lifespan of the mill, increasing maintenance costs and downtime, and negatively impacting production. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] Therefore, one objective of this utility model is to provide a Raymond mill with shock absorption effect. A shock absorption mechanism is set at the bottom of the Raymond mill to buffer the force generated by the vibration caused by the operation of the mill and the crushing of materials, and at the same time to release the remaining vibration energy in other directions in a reasonable manner, so as to avoid excessive concentration of vibration energy on the key components of the mill and damage to them.

[0006] To achieve the above objectives, the first aspect of this utility model proposes a Raymond mill with shock absorption effect, comprising: a Raymond mill, a conveying pipe, a discharge pipe, and a shock absorption mechanism, wherein the conveying pipe is disposed on the Raymond mill; the discharge pipe is disposed on the outer wall of the Raymond mill; the shock absorption mechanism includes multiple sets of telescopic rods, multiple sets of first springs, a base plate, and two sets of force relief components, wherein the multiple sets of telescopic rods are equidistantly disposed on the bottom wall of the Raymond mill, and the upper wall of the base plate is connected to the other end of the multiple sets of telescopic rods; the multiple sets of first springs are respectively sleeved on the outside of the corresponding telescopic rods, and one end of the multiple sets of first springs is connected to the bottom wall of the Raymond mill, and the base plate is connected to the other end of the multiple sets of first springs; the two sets of force relief components are symmetrically disposed between the base plate and the bottom wall of the Raymond mill.

[0007] In addition, the Raymond mill with shock absorption effect proposed above according to this utility model may also have the following additional technical features:

[0008] Specifically, the pressure relief assembly includes two sets of mounting plates, two sets of connecting blocks, two push plates, and a second spring. The two sets of mounting plates are respectively mounted on the Raymond mill and the base plate. One end of each of the two sets of connecting blocks is pivotally connected to the mounting plate, and the other end of each of the two push plates is pivotally connected to the corresponding connecting block. The two ends of the second spring are respectively connected to the side walls of the two push plates.

[0009] Specifically, a first connecting plate is provided at one end of the conveying pipe; a second connecting plate is provided at one end of the discharging pipe.

[0010] Specifically, the outer wall of the Raymond mill is equipped with a maintenance component, which includes a sealing door, two fixing plates, two fixing blocks, and two threaded bolts. The outer wall of the Raymond mill has an opening; the sealing door is pivotally connected to the outer wall of the Raymond mill; the two fixing plates are respectively set on the side wall of the sealing door; the two fixing blocks are respectively set on the outer wall of the Raymond mill; and the two threaded bolts pass through the corresponding fixing plates and are threadedly connected to the corresponding fixing blocks.

[0011] Specifically, the bottom wall of the base plate is equipped with rubber pads.

[0012] Compared with existing technologies, this invention has the following advantages: A shock-absorbing mechanism is installed at the bottom of the Raymond mill to buffer the forces generated by vibrations during mill operation and material crushing. Simultaneously, the remaining vibration energy is released in other directions, preventing excessive concentration of vibration energy on critical components of the mill and avoiding damage. This effectively reduces vibration damage to the Raymond mill's structure, extends its service life, lowers the frequency of equipment failures due to excessive vibration, reduces maintenance costs and downtime, and ensures stable and efficient milling production.

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0021] The Raymond mill with shock absorption effect according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0022] like Figures 1-4 As shown, the Raymond mill with shock absorption effect according to this utility model embodiment includes: Raymond mill 1, conveying pipe 2, discharge pipe 3 and shock absorption mechanism 4.

[0023] The conveying pipe 2 is installed on the Raymond mill 1, and the discharge pipe 3 is installed on the outer wall of the Raymond mill 1.

[0024] The shock absorption mechanism 4 includes multiple sets of telescopic rods 41, multiple sets of first springs 42, a base plate 43, and two sets of force relief components 44.

[0025] Multiple sets of telescopic rods 41 are equidistantly arranged on the bottom wall of Raymond mill 1. The upper wall of the bottom plate 43 is connected to the other end of the multiple sets of telescopic rods 41. Multiple sets of first springs 42 are respectively sleeved on the outside of the corresponding telescopic rods 41, and one end of the multiple sets of first springs 42 is connected to the bottom wall of Raymond mill 1. The bottom plate 43 is connected to the other end of the multiple sets of first springs 42. Two sets of pressure relief components 44 are symmetrically arranged between the bottom plate 43 and the bottom wall of Raymond mill 1.

[0026] The pressure relief assembly 44 includes two sets of mounting plates 441, two sets of connecting blocks 442, two push plates 443, and a second spring 444.

[0027] Two sets of mounting plates 441 are respectively installed on the Raymond mill 1 and the base plate 43. One end of the two sets of connecting blocks 442 is pivotally connected to the mounting plate 441. The two push plates 443 are pivotally connected to the other end of the corresponding connecting blocks 442. The two ends of the second spring 444 are respectively connected to the side walls of the two push plates 443.

[0028] Specifically, when the Raymond mill vibrates during the grinding process, the vibrations are transmitted to multiple sets of first springs 42 at the bottom. During this compression, the telescopic rod 41 limits the movement of the first springs 42. As the first springs 42 compress, the mounting plate 441 at the bottom of the Raymond mill 1 moves downwards, thereby pushing the push plate 443 via the connecting block 442 to compress the second spring 444. The compressed second spring 444 then pushes the push plate 443 back to its original position, releasing the vertical force generated by the vibration of the Raymond mill 1 to the left and right.

[0029] In one embodiment of this application, such as Figure 1 , Figure 3 and Figure 4 As shown, a first connecting plate 21 is provided at one end of the conveying pipe 2, and a second connecting plate 31 is provided at one end of the discharge pipe 3.

[0030] Specifically, the user can connect the conveying pipe 2 to the external device through the first connecting plate 21, thereby conveying the material into the Raymond mill 1. Then, the user can connect the recycling device through the second connecting plate 31, thereby outputting the crushed material to the recycling device through the discharge pipe 3.

[0031] In one embodiment of this application, such as Figure 1 and Figure 3 As shown, the outer wall of the Raymond mill 1 is equipped with a maintenance component 5.

[0032] The maintenance component 5 includes a sealing door 52, two fixing plates 53, two fixing blocks 54, and two threaded bolts 55.

[0033] The outer wall of the Raymond mill 1 has an opening 51, the sealing door 52 is pivotally connected to the outer wall of the Raymond mill 1, two fixing plates 53 are respectively set on the side wall of the sealing door 52, two fixing blocks 54 are respectively set on the outer wall of the Raymond mill 1, and two threaded bolts 55 pass through the corresponding fixing plates 53 and are threadedly connected to the corresponding fixing blocks 54.

[0034] Specifically, when maintenance and repairs are required inside the Raymond mill 1, the user can rotate the two threaded bolts 55 to remove them from inside the fixing block 54, and then rotate the sealing door 52, allowing the operator to enter the Raymond mill 1 through the opening 51. After maintenance, the operator can rotate the sealing door 52 to close the opening 51, and then rotate the two threaded bolts 55 in sequence. The threaded bolts 55 pass through the fixing plate 53 and are threadedly connected to the fixing block 54, thereby fixing the sealing door 52 to the Raymond mill 1.

[0035] In one embodiment of this application, such as Figure 1 As shown, a rubber pad 6 is provided on the bottom wall of the base plate 43.

[0036] Understandably, the rubber pad 6 installed on the bottom wall of the base plate 43 can increase the friction between the Raymond mill 1 and the ground, thereby preventing the Raymond mill 1 from shifting due to vibration.

[0037] In summary, by installing a shock-absorbing mechanism at the bottom of the Raymond mill, the force generated by the vibration caused by the operation of the mill and the crushing of materials can be buffered, and the remaining vibration energy can be released in other directions in a reasonable manner, so as to avoid excessive concentration of vibration energy on the key components of the mill and causing damage to them.
