Abstract
The utility model relates to a kind of roller dropping testing machine, solves existing roller dropping testing machine and cannot meet frangible biomass granule fuel fall-down test problem.This device comprises cylinder, cylinder bottom both sides are driven by driving wheel and roll, it is characterized in that: described inner wall of rotary drum is circumferentially evenly provided with some folding arms, folding arms towards rotating direction side is working face, fold arms working face root cylinder wall on be provided with screen cloth, the below outside described cylinder is provided with particle collection bucket, and particle collection bucket transverse width is greater than the radial width of cylinder, the lowest part of particle collection bucket is provided with feed opening, is provided with particle box of weighing below feed opening.The utility model arranges and folds arms in cylinder, biomass granule fuel can be taken up and fall; Root of folding arms arranges screen cloth, particle can be sifted out, rolling barrel, and can the loss of Real-Time Monitoring quality of material.
Description
Technical field
The utility model relates to a kind of fall-down test checkout gear, particularly a kind of roller dropping testing machine being suitable for biomass granule fuel.
Background technology
A lot of product, before production definition, needs to carry out anti-collision performance detection, and as mobile phone, draw-bar box etc., the general drop machine that adopts detects.For easy disrupted sample such as biomass granule fuels, need equally to detect biomass fuel pellet anti-collision performance, verify the particle integrity degree of biomass granule fuel under shock condition, improve the quality of products.Existing drum-type drop machine, mainly for the fall-down test of case and bag, mobile phone etc., can not produce tiny particle in this type of product testing process substantially.And for biomass granule fuel, particle in fall-down test process, can be produced, during to lasting test of many times, particle is difficult to remove in cylinder.And for the fall-down test of biomass granule fuel, mass loss rate is as the important indicator evaluated, and general quality and former whole grain mass ratio with remaining larger particles calculates; The particle being less than former particle certain percentage volume will be rejected.And on the other hand, the particle collected in process of the test oppositely can calculate mass loss rate equally.
CN 201233304Y patent application document disclosed in 6 days Mays in 2009 of Patent Office of the People's Republic of China, name is called a kind of trunk drum test machine, and this device carries out trunk drum test by the cylinder of hexagon inwall.This device cylinder both ends open, border seal, if be used for the cylinder fall-down test of biomass granule fuel, particle is difficult to remove, and when test of many times, has a negative impact to result of the test.
Summary of the invention
The purpose of this utility model is that solving existing roller dropping testing machine cannot meet frangible biomass granule fuel fall-down test problem, provides a kind of roller dropping testing machine being suitable for biomass granule fuel.
The utility model solves the technical scheme that its technical problem adopts: a kind of roller dropping testing machine, comprise cylinder, cylinder bottom both sides are driven by driving wheel and roll, described inner wall of rotary drum is circumferentially evenly provided with some folding arms, folding arms towards rotating direction side is working face, fold arms working face root cylinder wall on be provided with screen cloth, below outside described cylinder is provided with particle collection bucket, particle collection bucket transverse width is greater than the radial width of cylinder, the lowest part of particle collection bucket is provided with feed opening, is provided with particle box of weighing below feed opening.Biomass granule fuel is broken under tumbler test constantly clashes into produces particle, particle particle is when being less than screen cloth mesh, drop out outside cylinder from screen cloth, collected by particle collection bucket and fall into particle box of weighing, not only the particle in cylinder can be removed in real time, and can the mass loss rate of Real-Time Monitoring test specimen.
As preferably, described in the fold arms top of working face be provided with protruding block.Certain barrier effect can be played to the material on folding arms, fall after allowing material be taken to higher angle by folding arms, ensureing experiment effect.
As preferably, described screen cloth is dismountable plug in construction.According to the size of biomass fuel pellet, to the requirement of chaff size, screen mesh size can be changed.
As preferably, described drum shaft to two ends outer wall be respectively equipped with the driving raceway of annular protrusion, described driving wheel coordinates with driving rolling path rolling.
As preferably, described in fold arms arrange 3 ~ 5 on inner wall of rotary drum.
The utility model arranges and folds arms in cylinder, biomass granule fuel can be taken up and fall; Root of folding arms arranges screen cloth, particle can be sifted out, rolling barrel, and can the loss of Real-Time Monitoring quality of material.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the utility model.
Fig. 2 is the utility model driving wheel and the schematic side view driving raceway.
In figure: 1. cylinder, 2. drive raceway, 3. driving wheel, 4. fold arms, 5. screen cloth, particle box of 6. weighing, 7. particle collection bucket.
Detailed description of the invention
Also by reference to the accompanying drawings the utility model is further illustrated below by specific embodiment.
Embodiment: a kind of roller dropping testing machine, as shown in Figure 1 and Figure 2.The frame of this device is provided with cylinder 1, drum shaft to two ends outside be respectively equipped with the driving raceway 2 of annular protrusion, drive that the below of raceway is symmetrical is provided with driving wheel 3, driving wheel with drive raceway to coordinate to drive cylinder to rotate.
As shown in Figure 1, the inwall ring week of cylinder is evenly provided with three and folds arms 4, folding arms 4 is working face towards the side of rotating direction, and the upper end in drum functions face is provided with block, is to fold arms biomass granule fuel to be taken up higher angle.The cylinder wall of working face root of folding arms is provided with screen cloth 5, and screen cloth 5 is dismountable plug in construction, can select suitable screen size.Below outside cylinder is provided with particle collection bucket 7, and particle collection bucket 7 lateral dimension is greater than the radial dimension of cylinder.The bottom of particle collection bucket is provided with feed opening, and the below of feed opening is provided with particle box 6 of weighing.
Biomass granule fuel is sent in cylinder and is tested, and the particle produced in process of the test falls into particle collection bucket from screen cloth, then collects particle and weighs in box, can not only remove the particle in cylinder, and the mass loss rate of energy Real-Time Monitoring test material.
