Abstract
Description
Technical Field
[0001] This utility model relates to the field of roll gap measurement technology, and in particular to an auxiliary tool for measuring roll gap in a roll press. Background Technology
[0002] In cement production, roller presses extrude and pre-grind lumpy cement raw materials. This pre-grinding process effectively reduces the load on subsequent grinding processes. The size of the roller gap directly affects the extrusion effect of cement particles. A suitable roller gap allows the cement raw materials to be fully extruded, reducing the gaps between particles and increasing the specific surface area of the material. If the roller gap is too large, the material will not receive sufficient extrusion pressure, resulting in a large number of coarse particles in the product, affecting the strength development and other properties of the cement. Conversely, if the roller gap is too small, it may cause over-grinding, producing too much fine powder, which not only increases energy consumption but may also affect the rheological properties and setting time of the cement. Therefore, it is necessary to frequently and effectively measure the size of the roller gap. When measuring, since the radii of the two rollers are known, the size of the roller gap can be obtained by measuring the distance between the highest or lowest points of the two rollers and subtracting the radii of the two rollers.
[0003] Currently, common methods for measuring roll gap include feeler gauge measurement, displacement sensor measurement, and laser ranging. The feeler gauge measurement involves inserting multiple feeler gauges into the roll gap, and the thickness of the inserted feeler gauges represents the roll gap size. This method is inconvenient for measuring roll gaps that are located high up. While the displacement sensor measurement and laser ranging methods are easy to operate, they are more expensive. Furthermore, all of these methods require measuring only one point in the roll gap first, and if multiple points need to be measured, they must be measured separately, which is inconvenient.
[0004] Therefore, based on the above situation, it is necessary to design an auxiliary tool for measuring the roll gap of a roller press to solve the above problems. Utility Model Content
[0005] This invention provides an auxiliary tool for measuring the roll gap of a roller press, in order to solve the problem that existing technologies cannot simultaneously measure multiple points of the roll gap.
[0006] The technical problem solved by this utility model is achieved by the following technical solution:
[0007] An auxiliary tool for measuring the gap between rollers in a roller press includes a receiving plate and a lifting component. The receiving plate is provided with multiple sets of measuring units. Each set of measuring units includes two sets of measuring mechanisms arranged side by side at the same height. Each measuring mechanism includes multiple measuring elements. When one of the measuring elements touches the lowest point of the roller, this measuring element has the shortest length. The distance between the center points of the two rollers is obtained by measuring the distance between the two shortest measuring elements in the same measuring unit. The lifting component is located below the receiving plate and is used to drive the multiple sets of measuring units to move towards the lowest point of the roller.
[0008] Preferably, the measuring element includes a fixed rod connected to the receiving plate and a movable rod frictionally slidably connected inside the fixed rod.
[0009] Preferably, a touch switch is provided on the inner bottom surface of the fixing rod, and an indicator light electrically connected to the touch switch is provided on the receiving plate, with each indicator light corresponding to a measuring component.
[0010] Preferably, the receiving plate is provided with scale lines, and the scale lines correspond one-to-one with the measuring parts.
[0011] Preferably, an auxiliary frame is slidably connected to the receiving plate, and an abutment plate is provided on the movable rod. When the auxiliary frame contacts the abutment plate, it is used to pull the movable rod upward.
[0012] Preferably, the lifting component is equipped with a level.
[0013] The beneficial effects of this utility model are as follows: the lifting component drives the receiving plate to move upward, so that multiple sets of measuring units approach the pressure roller at the same time, and the measuring components on each set of measuring units contact the pressure roller at the same time, measuring different points of the pressure roller simultaneously. After the measurement is completed, observe the positions of the two shortest measuring components and measure the distance between the two shortest measuring components, which is the distance between the center points of the two pressure rollers. Subtract the radius of the two pressure rollers from this distance to obtain the size of the roller gap. The measurement is simple and convenient. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.
[0023] Reference Figures 1-6 As shown, an auxiliary tool for measuring the roll gap of a roller press includes a receiving plate 1 and a lifting component 3 located below the receiving plate 1. The lifting component 3 can be an electric telescopic rod, etc. In use, the roll gap size d1 is obtained by measuring the distance D between the center points of the two rollers and then subtracting the radius d of the two rollers from this distance. The distance between the center points of the two rollers is the distance between the highest or lowest points of the two rollers. Therefore, in actual operation, it can be used above or below the rollers depending on the application scenario. Taking the use below the rollers as an example, the lifting component 3 is placed on the ground, and then the receiving plate 1 is raised. At this time, multiple sets of measuring... The measuring units are positioned close to different locations on the pressure rollers to enable multi-point measurement. Simultaneously, two sets of measuring mechanisms within each measuring unit are positioned close to the two pressure rollers, ensuring that multiple closely arranged measuring elements 2 contact the pressure rollers at varying heights. The two shortest measuring elements 2 among the multiple measuring units represent the lowest points of the two pressure rollers. The distance between the two shortest measuring elements 2 in each measuring unit is measured using a ruler or similar tool. If the distances at all measuring points are the same, this represents the distance between the center points of the two pressure rollers. Subtracting the known radii d of the two pressure rollers from this distance D yields the roll gap size d1. This allows for the determination of roll gap sizes at multiple measuring points, making the operation simple and convenient.
[0024] Reference Figures 1-5 As shown, the measuring component 2 further includes a fixed rod 201 connected to the receiving plate 1 and a movable rod 202 frictionally slidably connected inside the fixed rod 201. During use, when the movable rod 202 contacts the surface of the pressure roller, the lifting action of the lifting component 3 causes the movable rod 202 to slide into the fixed rod 201, and under the action of friction, the movable rod 202 is fixed at this position. After the measurement is completed, the lifting component 3 lowers the receiving plate 1, and the lowered receiving plate 1 facilitates direct measurement of D.
[0025] Among them, such as Figure 5As shown, a touch switch 4 is provided on the inner bottom surface of each fixed rod 201, and an indicator light 5 is provided on the receiving plate 1 that is electrically connected to and corresponds to each touch switch 4. When a certain movable rod 202 first contacts the touch switch 4, the corresponding indicator light 5 lights up to remind the operator that the measurement is over. At this time, the receiving plate 1 can be moved down to stop the measurement, and then the distance between the two indicator lights 5 can be measured directly, which is more convenient.
[0026] Reference Figures 1-3 As shown, furthermore, the receiving plate 1 is provided with scale lines 6, with mm as the smallest unit. The scale on the scale line 6 corresponds one-to-one with the measuring piece 2, which can make the measurement more accurate, reduce measurement errors, and after the measurement is completed, the use of other rulers can be avoided, and the reading can be taken intuitively.
[0027] Reference Figures 1-5 As shown, an auxiliary frame 7 is slidably connected to the receiving plate 1. A handle can be set on the auxiliary frame 7. Then, an abutment plate 8 is provided on the movable rod 202. When the auxiliary frame 7 contacts the abutment plate 8, it is used to pull the movable rod 202 upward so that the height of all measuring parts 2 is restored to the same height, which is convenient for the next use.
[0028] Reference Figures 1-2 As shown, the lifting component 3 is further equipped with a level 9. The level 9 can be set to make it easy to adjust the overall level during use, prevent uneven placement from causing tilting during measurement, and reduce the measurement error of each point.
