Abstract
The utility model discloses a lower side plate for a high-pressure roller mill. The lower side plate comprises a lower side plate matrix, wherein a plurality of studs are assembled in stud holes formed in the left end surface of the lower side plate matrix and fixedly connected with the lower side plate matrix in a clearance fit manner; a support plate is fixedly connected to the upper side of the right end surface of the lower side plate matrix; the upper surface of the support plate is parallel to and level with the upper end surface of the lower side plate matrix; connection holes are formed in the upper end surface of the support plate. The studs processed by high-strength wear-resistant hard alloy are embedded into the lower side plate matrix, and the lower side plate matrix is made from a wear-resistant material, the wearing resistance is greatly increased.
Description
Technical field
The utility model belongs to the high-pressure roller mill technical field, relates in particular to a kind of high-pressure roller mill lower side panel.
Background technology
At present, high-pressure roller mill is as a kind of novel energy-conserving milling equipment, be widely used in the Metal mining exploitation, its at decrease in energy resource consumption, also realized how broken few the mill.The groundwork principle of high-pressure roller mill be by two compression rollers that rotate in opposite directions under the hydraulic system effect, produces huge extruding force with crushing material, the compression roller Life Relation of high-pressure roller mill arrives operation rate and maintenance cost.In order to improve roll-in efficiency, prevent that material screws out in cavity, must be in the side of two roller shells with the encircle a city cavity of a relative sealing of two side shields and lower side panel.the lower side panel of conventional roll press adopts the overall structure of built-up welding formula, utilize bolt to be connected with side shield, lower side panel, side shield and two compression rollers form confined space, making material have certain material in extrusion process presses, material enters next process through extruding along with the rotation of compression roller, equipment operation a period of time, because compression roller side and lower side panel are matched in clearance, certain wearing and tearing appear in lower side panel and compression roller side, and during the fine powder in operation process in material enters, make lower side panel wearing and tearing aggravation, pinch roller and side shield and lower side panel excesssive gap, thereby make side leak material, the local material of side is pressed not, the phenomenons such as the product squeezing effect is undesirable.Will aggravate the wearing and tearing of compression roller roller side after the lower side panel wearing and tearing, be unfavorable for the sustainable use of roller shell,, in case roller shell may wear to a certain degree, even whole roller shell will be scrapped, increase the duration and cost of maintenance of equipment.
Summary of the invention
The problem that exists for solving prior art; the purpose of this utility model is to provide a kind of high-pressure roller mill lower side panel; it is high that this lower side panel has hardness; wearability is good, and the characteristics such as long service life effectively improve operation rate; product granularity is produced active influence; simultaneously can also indirect protection roller shell side, slow down its rate of wear, limited extension device service life.
For achieving the above object, the utility model adopts technical scheme as described below:
A kind of high-pressure roller mill lower side panel, comprise the lower side panel parent, be fitted with several studs in the stud hole of offering on lower side panel parent left side, be fixedly connected with by gap fiting mode between stud and lower side panel parent, the upside of the right side of lower side panel parent is fixedly connected with gripper shoe, the upper surface of gripper shoe is concordant with the upper surface of lower side panel parent, offers connecting hole on the upper surface of gripper shoe.
Further, be filled with bonding agent between described stud and stud hole.
Further, the connecting hole on described gripper shoe is waist-shaped hole.
Further, be installed with brace rod on the lower surface of described gripper shoe.
Further, described stud adopts the high-strength wearable carbide alloy to make.
, owing to adopting technical scheme as above, the utlity model has following superiority:
The utility model is by inlay the stud that adopts the high-strength wearable carbide alloy to be processed on the lower side panel parent, and the employing high-abrasive material has increased wearability greatly as the lower side panel parent; In addition, connecting hole on gripper shoe adopts mounting hole, can regulate at the laggard line position of lower side panel parent wearing and tearing, guarantee between lower side panel parent and compression roller end face to keep enough little distance, the material that effectively prevents larger particles enters therebetween, and the wearing and tearing of aggravation lower side panel parent and roller end surface, and effectively prevent gap become large after, material presses the product particle that makes not after extruding larger herein.Lower side panel of the present utility model can effectively increase the service life, and indirect protection roller shell side, slow down its rate of wear, and product granularity is produced active influence.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is perspective view of the present utility model.
In figure: the 1-stud; 2-lower side panel parent; The 3-gripper shoe; The 4-connecting hole.
The specific embodiment
In conjunction with Fig. 1, Fig. 2 and Fig. 3, a kind of high-pressure roller mill lower side panel, comprise lower side panel parent 2, be fitted with the stud 1 that several adopt the high-strength wearable carbide alloy to be processed in the stud hole of offering on lower side panel parent 2 left sides, be equipped with by gap fiting mode between stud and stud hole, and be filled with bonding agent between stud and stud hole, be used for fastening stud, prevent the activity of stud; The upside of the right side of lower side panel parent is fixedly connected with gripper shoe 3, the upper surface of gripper shoe is concordant with the upper surface of lower side panel parent 2, offer connecting hole 4 on the upper surface of gripper shoe 3, be installed with brace rod on the lower surface of gripper shoe 3, be used for strengthening the support strength of gripper shoe.
Connecting hole 4 on described gripper shoe 3 is waist-shaped hole, be used for regulating at the laggard line position of lower side panel parent wearing and tearing, guarantee between lower side panel parent and compression roller end face to keep enough little distance, the material that effectively prevents larger particles enters therebetween, and the wearing and tearing of aggravation lower side panel parent and roller end surface, and effectively prevent gap become large after, material presses the product particle that makes not after extruding larger herein.
Described stud adopts the high-strength wearable carbide alloy to make.
During work; the wear-resisting lower side panel that is formed by hard alloy stud and lower side panel parent; during comminuting matter; owing between roller side and side shield and lower side panel, certain gap being arranged; in use, more tiny material enters wherein, thereby wearing and tearing are very fast; the hard alloy stud lower side panel, because its superior anti-wear performance will effectively be protected compression roller roller side, guarantees due material pressure and squeezing effect.The roller side also protection to a certain extent, thereby the life-span of compression roller is extended, thereby improve the service life of complete machine.
