Description

A kind of more partial size screening pulverizers
Technical field
The utility model belongs to experiment pulverizer technical field, and in particular to a kind of more partial sizes screening pulverizers.
Background technique
With the propulsion of Chinese Urbanization and modernization, energy shortage problem is got worse, to guarantee China's energy In sustainable development state, seeking new material becomes the inexorable trend of social development instead of traditional material.In new material Before investment application, it is necessarily required to carry out experimental study to its physical and chemical performance, the mechanism of action, function and effect etc..For Novel solid materials can nearly all be related in process of experimental crushing, screening process.Then, experiment pulverizer and sieve The presence of net is just particularly important, and is widely used in the laboratory of the departments such as coal, mine, chemical industry, environmental protection, geology, scientific research The laboratory and.
Laboratory disintegrator will be larger by modes such as cutting, shock, extruding using the interaction of moving knife and material Volume crushing material is at granular material.It is by structure compositions such as feed inlet, pulverizing chamber, Material collecting box for harvesting.Material is knocked down from feeding port Pulverizing chamber sorts through sieve after being crushed by high-speed rotating moving knife and stationary knife, falls into Material collecting box for harvesting, to obtain granular material.
Laboratory disintegrator is broadly divided into three classes: laboratory seal jaw crusher, laboratory sealing beater grinder and The sealed Double roll crusher in laboratory.Laboratory seal the coarse crushing of jaw crusher energy, in the broken lower material of compression strength, and grain Degree is uniform, discharging-material size is adjustable;But its crush efficiency is low, attrition is bigger.Laboratory seals beater grinder powder Broken ratio is big, efficiency, low energy consumption, and product granularity is uniform;But its structure is complex so that maintenance work also becomes complicated, and price compared with It is expensive.The sealed Double roll crusher crush efficiency in laboratory is high, and discharging-material size is adjustable, low noise when use;But it can not be crushed Hard material, discaling roll is easy to wear, and production efficiency is lower.In addition, these three types of laboratory disintegrators cannot screen material Classification, and be frequently necessary to carry out sifting sort to smashed material in an experiment for studying, so that experimentation is a bit numerous It is trivial.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned the deficiencies in the prior art, a kind of collection sound insulation, crushing, screening etc. are provided Multiple functions screen pulverizer in more partial sizes of one.
The above-mentioned purpose of the utility model is realized by the following technical solutions: more partial sizes screen pulverizer, It includes grinding barrel, matches at the top of grinding barrel and is set with lid and forms a confined space therewith, on the central axes of grinding barrel Shaft is installed, Disintegrating knife is installed in shaft;The shaft is connected to motor by being installed on the bearing of grinding barrel bottom, Motor is installed on the pedestal under grinding barrel, and pedestal is equipped with time switch and air overload protective device;In grinding barrel For the installation of Disintegrating knife lower part there are three the sieve of different pore size, three sieves are in same level, with described turn Axis in axis line is the concentric loop in the center of circle, and the aperture of three sieves from the inside to the outside is sequentially increased;It is corresponding under three sieves to set There are three the screening slots of circular ring shape, for receiving the comminuting matter under three different pore size sieve screenings respectively.
Specifically, the sieve of three different pore sizes, the partial size that sieve from the inside to the outside is sieved is respectively: 150~ 200 mesh, 100~150 mesh, 50~100 mesh.
Compared with prior art, the utility model has the beneficial effects that by being arranged below Disintegrating knife with a variety of The circular ring shape sieve of mesh size and the screening slot to match with sieve, so that the material after Disintegrating knife crushed is being centrifuged It gets rid of under power effect to each position of sieve and is sieved, and then enter corresponding screening slot, to obtain different-grain diameter Material eliminates subsequent screening step.Also, the utility model structure is simple, and crush efficiency is high, makes full use of Disintegrating knife The centrifugal force size generated to material gets rid of the material of different-grain diameter to the sieve of different mesh sizes, and screening effect is good, energy consumption It is low.
Detailed description of the invention
Fig. 1 is the integral outer structural schematic diagram of the utility model embodiment.
Fig. 2 is the inside top figure of Fig. 1.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples.
Referring to Fig. 1, Fig. 2, the present embodiment includes grinding barrel 2, the top of grinding barrel 2 be set with lid 1 and with 1 shape of lid At a closed space.Shaft 3 is installed on the central axes of grinding barrel 2, Disintegrating knife 4 is installed in shaft 3.Shaft 3 Bearing 11 by being installed on 2 bottom of grinding barrel is connect with motor 12, and motor 12 is installed on the pedestal 15 under grinding barrel 2, Pedestal 15 is equipped with time switch 14 and air overload protective device 13.It can be seen in fig. 2 that under the Disintegrating knife 4 in grinding barrel 2 There are three the sieves of different pore size for portion's installation, it may be assumed that sieve 5, sieve 6, sieve 7.Sieve 5, sieve 6, sieve 7 are in same water In plane, using the central axes of shaft 3 as the concentric loop in the center of circle, the aperture of three sieves from the inside to the outside is sequentially increased, sieve 5, The partial size that sieve 6, sieve 7 are sieved is respectively: 150~200 mesh, 100~150 mesh, 50~100 mesh.Sieve 5, sieve 6, sieve The corresponding screening slot set there are three circular ring shape under net 7, it may be assumed that screening slot 8, screening slot 9, screening slot 10, for receiving respectively Comminuting matter under sieve 5, sieve 6, the screening of sieve 7.It is the plane of screening slot 8,9,10 and the flat shape of sieve 5,6,7, big It is small identical, it is split to form by thickness iron hoop identical with thin iron bandwidth.Material after Disintegrating knife 4 crushed from It is got rid of under mental power function to each position of sieve 5,6,7 and is sieved, and then enter corresponding screening slot 8,9,10, to obtain Obtain the material of different-grain diameter.
The primary structure composition, implementation principle and main feature of the utility model has been shown and described above.The industry Technical staff is it should be appreciated that the present utility model is not limited to the above embodiments, and described in the above embodiment and specification It is to illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model can also There are various change and improvement, these changes and improvements are both fallen in the range of the requires of the utility model protection.The utility model is wanted Protection scope is asked to be defined by the appending claims and its equivalent thereof.
