Abstract
Description
Technical Field
[0001] This utility model relates to the field of vertical mill technology, and in particular to a material stabilization device for a vertical mill. Background Technology
[0002] A vertical roller mill is a large-scale grinding equipment, often simply referred to as a vertical mill. The grinding process in a vertical roller mill is accomplished by a grinding device (i.e., grinding rollers and a grinding disc), where materials are ground into powder between the rollers and the disc. The movement of the grinding device is driven by the rotation of the grinding disc, which in turn drives the grinding rollers. A stable material layer is one of the important conditions for ensuring the efficient and stable operation of a vertical roller mill.
[0003] Publication number CN219615684U discloses a material stabilizing device for a vertical mill, comprising a material layer body, a hollow push rod installed on the top surface inside the material layer body, and a scraper sleeved on the outer circumferential surface of the push rod. The scraper is equipped with an assembly counterweight component and a limiting component. The assembly counterweight component includes a counterweight block, an assembly protrusion, and a magnetic column. A first assembly groove is formed on the top surface of the scraper, and a first magnetic hole is formed on the bottom wall of the first assembly groove. The counterweight block is movably sleeved on the outer circumferential surface of the push rod and located above the scraper through a circular through-slot at the center of its top surface. One end of the assembly protrusion is fixed at the corner of the bottom surface of the counterweight block, and the other end extends movably into the first assembly groove. The limiting component includes a lead screw, a tray, a hinge rod, and a limiting strip. A strip-shaped through-slot is formed on the outer circumferential surface of the push rod, and the lead screw is movably disposed on the inner wall of the push rod. The tray is threadedly connected to the lead screw. This utility model offers flexible and convenient overall operation and adjustment while maintaining high assembly stability.
[0004] Although the above solution allows for flexible adjustment of the counterweight components on the assembly material layer, the limiting components are prone to displacement, affecting the effect, and the counterweight components are prone to falling off during installation. Therefore, we propose a stabilizing device for the material layer of a vertical mill. Utility Model Content
[0005] The main purpose of this utility model is to provide a stabilizing device for the material layer of a vertical mill. By setting up an assembly unit and a limiting unit, it solves the problems that the limiting component is easy to shift and affect the effect, and the counterweight component is easy to fall off during the installation process.

A strip-shaped mounting groove is opened on the inner walls of the upper and lower sides of the rectangular frame plate. The lead screw is movably mounted on one of the strip-shaped mounting grooves. There are four support blocks in total, divided into two groups. The two groups of support blocks are located on the two strip-shaped mounting grooves respectively. One group of support blocks is respectively matched with the two symmetrically arranged positive and negative threads on the lead screw. An adjusting plate is fixedly installed between every two support blocks located on the same vertical center horizontal plane. A set of positioning grooves is opened on the side surface of the adjusting plate facing the vertical center axis of the rectangular frame plate. Every two plug-in blocks are symmetrically fixed on opposite sides of the counterweight block, and the plug-in blocks extend movably into the positioning grooves.
[0009] Preferably, there are two T-shaped bars, which are symmetrically arranged on the inner wall of the bottom surface of the rectangular frame plate, and the T-shaped through grooves are arranged in a one-to-one correspondence with the T-shaped bars.

[0015] 1. In this utility model, by setting up an assembly unit, when the counterweight is assembled on the scraper on the material layer body, the counterweight can be placed inside the rectangular frame plate. After the T-shaped through groove on the top surface of the counterweight is aligned with the T-shaped strip on the inner wall of the bottom surface of the rectangular frame plate, the counterweight can be sleeved and placed on the outer circumference of the T-shaped strip and the placement angle is determined. All counterweights can be quickly assembled and stacked, and the installation process of the equipment counterweight components is stable and simple.
[0016] 2. In this utility model, by setting a limiting unit, by holding and rotating the screw in both directions outside the rectangular frame, two of the support blocks connected to the screw threadedly move relative to each other under the force, which can help the two adjusting plates adjust the distance inside the rectangular frame. The other two support blocks can slide and translate on the guide rod to cooperate with the adjustment plates and provide auxiliary support. After the two adjusting plates come closer to each other, the plug-in blocks on both sides of all the counterweight blocks can be inserted into the positioning grooves on the adjusting plates, and all the counterweight blocks are locked synchronously. The equipment has high stability in limiting the counterweight components. Attached Figure Description
