Abstract
The utility model discloses a sample preparationcrusher capable of preventing bonding and blockage phenomena and meeting the requirement for crushed particle sizes. The crusher comprises a box body arranged on a rack, wherein an opening is formed above one end of the box body, a feed hopper is arranged at the opening, and a discharging port is arranged below the other end of the box body. The crusher is characterized in that a central shaft which is arranged horizontally and driven by a power device is arranged in the box body, hammer heads distributedspirally in an equally-divided manner are arranged on the central shaft and inclined, and included angles formed by hammer surfaces of the hammer heads and a central axis of the central shaft are in a range of 135-175 degrees. According to the crusher, a sieve plate structure of an old crusher is omitted, so that the crusher is simple in structure and convenient to maintain, and the problems of bonding and blockage caused by extrusion of materials are solved; the materials are crushed fully and delivered while being crushed, the crusher is continuous and time-saving in working, and the working efficiency is improved.
Description
Technical field
The utility model relates to a kind of industrial sample making apparatus, relates to specifically a kind of crusher for preparing specimens.
Background technology
Sample preparation, object is by the material sample gathering, and is prepared into the analysis sample sample that can represent original material sample through fragmentation, mixing and division supervisor.(national standard or professional standard) method is taked representative sample in accordance with regulations, then carries out sample preparation and analysis.By sample preparation and analysis, to grasp its material characteristic, thereby factory inspection is received and control quality of material provides foundation in order to enter.
A large amount of enterprises that use the materials such as coal, ore such as thermal power generation, metallurgy, chemical industry often need to use sampling machine.Gather and process in the sample course of work entering the materials such as factory's coal, coke, ore, the sample of taking needs sample to carry out fragmentation carrying out before assay, and efficiency and performance requirement to disintegrating machine are higher.And from the actual situation with disintegrating machine, all do not reach the state of actual needs.Entering, sample moisture is too high; When granularity is larger, easily there is sticky stifled situation.Disintegrating machine occurs that sticky stifled phenomenon is much due to for ensureing that particle size after cracking is less than 13mm and is provided with netted sieve plate in disintegrating machine, or increase because wearing and tearing after disintegrating machine use a period of time cause tup and crusher inner chamber spacing, cannot crusher inner chamber and sieve plate effectively be swept and be caused.
Now on market, there is a kind of nothing sieve standing crusher at present, in vertical vertical cylindrical shell, there are vertical shaft and the tup of High Rotation Speed, material is in the time falling in cylindrical shell, because the time of falling bodies is shorter, vertical shaft and tup have little time to smash material, block is just discharged from cylindrical shell below, does not reach the granularity requirements needing after fragmentation, therefore can not meet the on-the-spot object using.
How to ensure particle size after cracking in prescribed limit and the wearing and tearing of the tup of disintegrating machine still can continue to maintain good performance, the life cycle of extension device after shortening.Solve the frequent generation of sticky stifled phenomenon, reduce the on-the-spot maintenance workload using, become industry to be badly in need of the work solving.
Summary of the invention
The purpose of this utility model is to provide a kind of crusher for preparing specimens of avoiding that sticky stifled phenomenon occurs and meeting crushing granularity requirement.
The utility model is to adopt following technical scheme to realize its goal of the invention, a kind of crusher for preparing specimens, it comprises the casing being located in frame, the top of casing one end is provided with opening, and opening part is provided with feed hopper, and the below of the casing other end is provided with discharging opening, in casing, be provided with the horizontally disposed axis being driven by power, axis is provided with and is the tup that spiral decile display distributes, and tup inclination, and the flat side of a hammer of tup becomes 135～175 degree angles with the axis of axis.
The utility model is for abundant fragmentation, and on described axis, in the hand of spiral, adjacent tup partly overlaps in orthographic projection.
The utility model is in order to extend the broken time, and described casing is that Horizontal type is cylindric, long 80 ㎝～150 ㎝ of casing.
The utility model is in order to alleviate maintenance work intensity, to reduce maintenance time, with bolts between tup and axis, and disassembling, assembling and replacing is convenient.
Owing to adopting technique scheme, the utility model has been realized goal of the invention preferably, and it has omitted the sieve-plate structure of old disintegrating machine, simple in structure, easy to maintenance, the sticky stifled problem having caused while having solved material extruding; The broken abundant and limit broken limit conveying of material, work saves time continuously, has improved operating efficiency.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As seen from Figure 1, Figure 2, plant crusher for preparing specimens, it comprises the casing 7 being located in frame 8, the top of casing 7 one end is provided with opening 2, and opening 2 places are provided with feed hopper 1, and the below of casing 7 other ends is provided with discharging opening 6, in casing 7, be provided with the horizontally disposed axis 3 being driven by power 9, axis 3 is provided with and is the tup 4 that spiral decile display distributes, and tup 4 tilts, and the flat side of a hammer 5 of tup 4 becomes 135～175 to spend angles (the present embodiment is 160 degree) with the axis of axis 3.
The utility model is for abundant fragmentation, on described axis 3, in the hand of spiral, adjacent tup 4 (for example partly overlaps in orthographic projection, the present embodiment tup 4 is arranged as 4 groups, be positioned at one group of tup 4 of casing 7 tops and the adjacent one group of projection on the trunnion axis cross section of axis 3 that is tending towards level, the projection section of the two is overlapping).
The utility model is in order to extend the broken time, and described casing 7 is that Horizontal type is cylindric, casing 7 long 80 ㎝～150 ㎝ (the present embodiment is 100 ㎝).
The utility model is in order to alleviate maintenance work intensity, to reduce maintenance time, with bolts between tup 4 and axis 3, and disassembling, assembling and replacing is convenient.
In the utility model when work,, (the present embodiment adopt be motor-driven belt pulley) drives axis 3 High Rotation Speeds in casing 7 to turn on the power 9, drives to be immediately the tup 4 that decile display is distributed in axis 3 and to rotate; Now the sample collecting from material is dropped into from the feed hopper 1 of the opening 2 of casing 7 tops, sample freely falling body is to being positioned under opening 2 on the tup 4 on axis 3, the tup 4 of High Rotation Speed hits broken to material, because tup adjacent on axis 34 partly overlaps in orthographic projection, and casing 7 is that Horizontal type is cylindric, the tube length 80-150 ㎝ (the present embodiment is 100 ㎝) of casing 7, has extended the broken time, therefore can pulverize fully; And the flat side of a hammer 5 of tup 4 becomes 135～175 degree (the present embodiment is 160 degree) angles with horizontal line, the component producing in shattering process is carried to casing 7 other ends in material is hit for more than 4 time by tup, then drop out from the discharging opening 6 of casing 7 other end belows, complete shattering process.Because discharging opening 6 is the unenclosed construction without sieve plate, the sticky stifled problem having caused while having solved material extruding.Meanwhile, tup 4, in larger wear range, still can continue to keep ability to work, the life cycle that has extended disintegrating machine.
