Technical Field

[0001] This utility model relates to the field of vacuum ball mill jar technology, and in particular to a vacuum stainless steel ball mill jar for ball mills. Background Technology

[0002] Ball mills are commonly used equipment in materials preparation and scientific research, and the grinding jar, as a key component, plays a decisive role in the grinding effect. Vacuum stainless steel ball mill jars are widely used in organic and inorganic acids of different concentrations and temperatures, especially in oxidizing media, where they exhibit good corrosion resistance, excellent high-temperature stress fracture resistance, and high-temperature creep resistance.

[0003] In existing technologies, threaded connections are cumbersome and time-consuming when frequently opening and closing the grinding jar. Threaded connections are also prone to wear and deformation, which can lead to a decrease in sealing performance and poor sealing effect. This makes it difficult to maintain a stable vacuum environment inside the grinding jar, thereby affecting the grinding effect on some environmentally sensitive materials and reducing product quality. Utility Model Content

[0004] The purpose of this invention is to solve the problems of complex operation and unstable sealing performance in the existing technology, and to propose a vacuum stainless steel ball mill jar for ball mills.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a vacuum stainless steel ball mill jar for a ball mill, comprising a fixed base, a vacuum jar body fixedly connected to the top of the fixed base, a jar lid fixedly connected to the top of the vacuum jar body, a first sealing ring fixedly connected to the top of the inner wall of the vacuum jar body, and a second sealing ring fixedly provided at the bottom of the inner wall of the jar lid. The first and second sealing rings cooperate with each other. A fastening structure is provided at the top of the jar lid. Slots are provided at both ends of the top edge of the jar lid. Connecting components are provided inside the slots. A connecting cover is fixedly connected to the center of the top of the jar lid. A groove is provided on the upper surface of the connecting cover. The inside of the groove engages with the bottom end of the fastening structure.

[0006] Furthermore, the connecting assembly includes a fixing bolt, a connecting groove is formed on the outer surface of the bottom of the fixing bolt, a locking block is slidably connected inside the connecting groove, a telescopic spring is fixedly connected to the end of the locking block away from the connecting groove, and a lever is fixedly connected above the locking block, so as to conveniently and quickly achieve the effect of connecting and disassembling the can lid and the can body.

[0007] Furthermore, the fixing bolt is connected through to the edge of the top of the vacuum tank body, and the end of the telescopic spring away from the locking block is fixedly connected to the inner wall of the slot, thus ensuring the stable operation of the connecting components.

[0008] Furthermore, the fastening structure includes a lead screw, a connecting block is fixedly connected to the bottom end of the lead screw, a limit plate is threadedly connected to the outer surface of the lead screw, a positioning bracket is provided above the limit plate, the positioning bracket is threadedly connected to the outer surface of the lead screw, and a turntable is fixedly connected to the top end of the lead screw. The can lid can be fastened and loosened by a simple rotation operation, which effectively improves the sealing performance.

[0009] Furthermore, the fixed base includes an annular plate, and a support plate is fixedly connected to the top edge of the annular plate. The surface of the support plate is provided with a connection port. The support plate has three sets distributed in a circle on the outer surface of the annular plate, which achieves the effect of providing stable support for the vacuum tank body and facilitating connection with the fastening structure.

[0010] Furthermore, the connection port is provided in three sets, and the limiting plate of the fastening structure is engaged inside the connection port, thereby ensuring a stable and reliable fastening operation.

[0011] Furthermore, a vacuum nozzle is connected through the top of the can lid. There are three vacuum nozzles arranged in a circle on the top of the can lid, which improves the vacuuming effect and the grinding quality.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, through the design of the connecting components, by utilizing structures such as fixing bolts, locking blocks and telescopic springs, the connection and disassembly between the can lid and the vacuum can body are realized quickly and conveniently. Compared with the traditional threaded connection method, it greatly saves operation time and labor costs and improves work efficiency.

[0014] 2.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a vacuum stainless steel ball mill jar for a ball mill, including a fixed base 1, a vacuum jar body 2 fixedly connected to the top of the fixed base 1, a jar lid 3 fixedly connected to the top of the vacuum jar body 2, a first sealing ring 21 fixedly connected to the top of the inner wall of the vacuum jar body 2, a second sealing ring 22 fixedly provided at the bottom of the inner wall of the jar lid 3, the first sealing ring 21 and the second sealing ring 22 cooperating with each other, a fastening structure 4 provided at the top of the jar lid 3, slots 31 are provided at both ends of the top edge of the jar lid 3, a connecting component 32 is provided inside the slots 31, a connecting cover body 33 is fixedly connected to the center of the top of the jar lid 3, a groove is provided on the upper surface of the connecting cover body 33, and the inside of the groove is engaged with the bottom of the fastening structure 4.

[0023] The following section will explain the specific settings and functions of its fastening structure 4 and connecting component 32.

[0024] In this embodiment: the connecting component 32 includes a fixing bolt 321, a connecting groove 322 is provided on the outer surface of the bottom of the fixing bolt 321, a locking block 323 is slidably connected inside the connecting groove 322, a telescopic spring 324 is fixedly connected to the end of the locking block 323 away from the connecting groove 322, and a paddle 325 is fixedly connected to the top of the locking block 323.

[0025] The aforementioned components achieve the following effect: When installing the ball mill jar, the jar lid 3 is placed on top of the vacuum jar body 2, aligning the retaining bolt 321 with the corresponding insertion hole on the top edge of the vacuum jar body 2. As the jar lid 3 moves downward, during the insertion of the retaining bolt 321 into the insertion hole, the insertion hole wall of the vacuum jar body 2 presses against the locking block 323, causing it to slide into the connecting groove 322 and compressing the telescopic spring 324. When the retaining bolt 321 is fully inserted, the locking block 323 corresponds to the slot on the vacuum jar body 2. At this time, the telescopic spring 324 rebounds, pushing the locking block 323 into the slot, thereby quickly connecting the jar lid 3 and the vacuum jar body 2 together. The operation is simple and efficient. When it is necessary to remove the can lid 3, by moving the lever 325, the locking block 323 is driven to retract into the connecting groove 322 against the elastic force of the telescopic spring 324, so that the locking block 323 is disengaged from the groove of the vacuum can body 2, and then the fixing bolt 321 can be pulled out from the insertion hole, realizing the separation of the can lid 3 from the vacuum can body 2, which greatly improves the convenience of assembly and disassembly in daily use of the ball mill jar.

[0026] Specifically, the fixing bolt 321 is connected through to the edge of the top of the vacuum tank body 2, and the end of the telescopic spring 324 away from the locking block 323 is fixedly connected to the inner wall of the slot 31.

[0027] In this embodiment: the fastening structure 4 includes a lead screw 41, a connecting block 42 is fixedly connected to the bottom end of the lead screw 41, a limit plate 43 is threadedly connected to the outer surface of the lead screw 41, a positioning bracket 44 is provided above the limit plate 43, the positioning bracket 44 is threadedly connected to the outer surface of the lead screw 41, and a turntable 45 is fixedly connected to the top end of the lead screw 41.

[0028] The effect achieved by the above components is as follows: After the ball mill jar is assembled, rotating the turntable 45 drives the lead screw 41 to rotate. Because the limiting plate 43 is engaged within the connection port 13 of the fixed base 1, the radial movement of the lead screw 41 is restricted. The lead screw 41 can only move up and down under the threaded engagement of the limiting plate 43 and the positioning bracket 44. As the lead screw 41 rotates, the positioning bracket 44 moves downward along the lead screw 41, and the connecting block 42 at the bottom of the lead screw 41 pushes the connecting cover 33, thereby pressing the jar cover 3 tightly onto the vacuum jar body 2. The first sealing ring 21 and the second sealing ring 22 further deform under pressure, filling the tiny gaps between the jar cover 3 and the vacuum jar body 2, significantly enhancing the sealing performance of the ball mill jar, ensuring a stable vacuum environment inside the jar, providing a guarantee for high-quality grinding of materials, and facilitating subsequent operations.

[0029] Specifically, the fixed base 1 includes an annular plate 11, and a support plate 12 is fixedly connected to the top edge of the annular plate 11. The surface of the support plate 12 is provided with a connection port 13, and the support plate 12 is distributed in three groups in a circular pattern on the outer surface of the annular plate 11.

[0030] The aforementioned components achieve the following effects: the annular plate 11 provides a stable support foundation for the entire grinding jar, ensuring that the grinding jar can be placed stably on the worktable without easily shaking. When the fastening structure 4 is in operation, the limiting plate 43 engages with the connecting port 13, limiting the radial displacement of the lead screw 41. This ensures that during the rotation of the lead screw 41, the positioning bracket 44 can stably apply vertical downward pressure to the jar cover 3, making the jar cover 3 fit tightly against the vacuum jar body 2, thereby improving the overall stability and sealing reliability of the grinding jar.

[0031] Specifically, the connection port 13 is provided with three sets, and the limiting plate 43 of the fastening structure 4 is snapped into the inside of the connection port 13.

[0032] Specifically, a vacuum nozzle 34 is connected through the top of the can lid 3, and there are three vacuum nozzles 34 distributed in a circle on the top of the can lid 3.

[0033] Working principle: When preparing to use the ball mill jar, first place the material to be ground into the vacuum jar body 2, then place the jar lid 3 on top of the vacuum jar body 2. Insert the fixing bolt 321 in the connecting assembly 32 into the insertion hole at the top edge of the vacuum jar body 2. With the cooperation of the locking block 323 and the telescopic spring 324, the jar lid 3 is quickly connected to the vacuum jar body 2. Next, rotate the turntable 45 of the fastening structure 4 to rotate the lead screw 41, which drives the positioning bracket 44 to move downward, thereby pressing the jar lid 3 tightly onto the vacuum jar body 2. The first sealing ring 21 and the second sealing ring 22 fit tightly together to ensure good sealing performance.

[0034] Then, a vacuum pump is connected to the three vacuum nozzles 34 arranged in a circle on the top of the can lid 3 to perform a vacuuming operation inside the ball mill can, removing the air inside the can and creating a vacuum environment suitable for material grinding. After the ball milling is completed, first rotate the turntable 45 in the reverse direction to loosen the can lid 3, and then move the lever 325 to retract the locking block 323, pulling the fixing bolt 321 out of the vacuum can body 2, so that the can lid 3 can be opened and the ground material can be taken out.
