Description

Technical Field

[0001] The utility model belongs to the technical field of PCD raw material production, and particularly relates to a grinding device for PCD raw material production. Background Art

[0002] PCD is polycarbonate diol, which is a polymer with hydroxyl groups at both ends of the molecule. Compared with the polyols used in the past, the heat resistance, weather resistance and friction resistance of the urethane produced with it as raw material are all improved. Diamond polycrystalline PCD is made by sintering fine-grained diamond single crystals under high temperature and high pressure. This product has excellent wear resistance, thermal stability, compressive strength and impact toughness, and is widely used in geological exploration, oil extraction, natural gemstone processing, and mechanical processing and finishing tools. The processing of polycrystalline diamond PCD requires diamond powder and nickel powder as raw materials, and grinding is required during the production of PCD raw materials. In the existing technology, ball milling is generally carried out through a horizontal grinding cylinder, which has a slow grinding speed, a long grinding time and low efficiency. Therefore, a new type of grinding device is needed. Utility Model Content

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide a grinding device for producing PCD raw materials, thereby solving the problems in the above-mentioned background technology.

[0004] The present invention achieves its objectives by providing a grinding device for producing PCD raw materials, comprising a grinding barrel, a feed assembly disposed at the upper end of the grinding barrel, a discharge assembly disposed at the lower end of the grinding barrel, and a grinding assembly disposed within the grinding barrel. The grinding assembly comprises an inner barrel disposed within the grinding barrel, the inner barrel having a plurality of through-holes formed in its peripheral sidewalls, a plurality of grinding balls disposed within the inner barrel, a vertically upwardly extending connecting shaft fixedly connected to the inner bottom surface of the inner barrel, and a drive assembly connected to the upper end of the connecting shaft. A baffle is rotatably sleeved on the outer wall of the connecting shaft, the baffle being slidably connected to the connecting shaft and connected to an auxiliary assembly. During use, raw materials are poured into the feed assembly through the previous process, and the raw materials flow into the inner barrel after passing through the feed assembly. The drive assembly drives the connecting shaft to rotate, thereby driving the inner barrel. During the rotation of the inner barrel, the grinding balls within the inner barrel move and collide with the raw materials to grind them. Simultaneously, during the rotation of the inner barrel, the ground raw materials are thrown out of the inner barrel by centrifugal force. Once the diameter of the raw material is reduced to a size smaller than the through-hole, centrifugal force forces it through the through-hole into the grinding barrel. The material then flows through the discharge assembly to the next process step. A baffle prevents the material or grinding balls from accidentally leaking out of the inner barrel during rotation. This device reduces grinding time by one-third during PCD material grinding, resulting in high efficiency.

[0005] Furthermore, the auxiliary assembly includes a vertical plate fixedly connected to the upper sidewall of the inner drum and extending upward. The upper end of the vertical plate is fixedly connected to a horizontal plate. The lower surface of the horizontal plate is fixedly provided with an electric push rod, and the lower end of the electric push rod is connected to the baffle. During use, the baffle moves upward or downward along the connecting axis by extending or contracting the electric push rod. When adding raw materials to the inner drum, the baffle moves upward. When grinding, the baffle moves downward to block the upper end of the inner drum, effectively preventing the raw materials or grinding balls from accidentally splashing out of the inner drum.

[0006] Furthermore, the driving assembly includes a front vertical plate and a rear vertical plate fixedly connected to the upper end of the grinding barrel, and the front vertical plate and the rear vertical plate are arranged corresponding to each other, the upper ends of the front vertical plate and the rear vertical plate are connected through a supporting plate, and a motor with an output shaft extending downward is fixedly provided on the lower surface of the supporting plate, and the output shaft of the motor is connected to the upper end of the dormitory connecting shaft.

[0007] Furthermore, the feeding assembly includes an inclined channel fixedly connected to the upper end of the grinding barrel, a cache groove is fixedly provided at the upper end of the inclined channel, and the interior of the cache groove is connected to the interior of the tilting plate channel.

[0008] Furthermore, an extension plate is fixedly provided at the lower end of the inclined channel, and the lower end of the extension plate faces the inner direction of the inner tube.

[0009] Furthermore, the discharge assembly includes a discharge pipe arranged at the bottom of the grinding barrel, a negative pressure device is provided inside the discharge pipe, and the outer end of the discharge pipe is connected to the next process.

[0010] Furthermore, an annular groove is provided on the inner bottom surface of the grinding barrel, and a guide protrusion is fixedly provided on the outer bottom surface of the inner cylinder. The guide protrusion is slidably connected in the annular groove. Through the mutual cooperation between the guide protrusion and the annular groove, the inner cylinder is more stable during rotation.

[0011] The beneficial effects of this utility model include: the interaction between the guide protrusion and the annular groove ensures greater stability during rotation of the inner drum. The extension or contraction of the electric push rod drives the baffle plate upward or downward along the connecting shaft. When adding raw materials to the inner drum, the baffle plate moves upward; when grinding, the baffle plate moves downward to block the upper end of the inner drum, effectively preventing the raw materials or grinding balls from accidentally spilling out. Raw materials are poured into the feed assembly during the previous process, passing through the feed assembly and then flowing into the inner drum. The drive assembly rotates the connecting shaft, which in turn drives the inner drum. This rotation drives the grinding balls inside the drum, which collide with the raw materials, grinding them. Simultaneously, centrifugal force propels the ground raw materials out of the drum during rotation. When the diameter of the raw materials is reduced to a value smaller than the diameter of the through-hole, centrifugal force forces the raw materials out of the inner drum, through the through-hole, and into the grinding barrel. The raw materials then flow through the discharge assembly to the next process. The baffle plate prevents the raw materials or grinding balls from accidentally spilling out of the inner drum during rotation. The utility model has a short grinding time during the process of grinding PCD raw materials, shortening the grinding time by one third, and has high working efficiency.
