Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 to 12, the energy-saving and environment-friendly crushing device for construction engineering of the present invention comprises a housing 11, a first annular filter screen belt 21, a first crushing assembly, a second annular filter screen belt 22, a second crushing assembly and a discharging belt 13. A feed opening 12 is formed in the right side of the upper end of the shell 11, and a first transmission device and a second transmission device which are vertically arranged are arranged in the shell 11.
The first endless screen belt 21 is mounted to a first drive means to receive the material from the feed opening 12 and is driven by the first drive means to rotate clockwise, the first drive means causing the first endless screen belt 21 to be inclined with the lower left and the higher right, and causing the first endless screen belt 21 to have a tensioned first upper section and a slack first lower section below the first upper section, such that a portion of the material screened by the first upper section falls from the left end of the first upper section, the remainder of the material passes through the first upper section, and the first lower section causes at least a portion of the remainder of the material to collect in the left section of the first lower section and fall through the first lower section. The first crushing assembly is configured to receive and crush material falling from the left end of the first upper section.
The second annular filter screen belt 22 is located below the first annular filter screen belt 21 and the first crushing assembly to receive the material filtered by the first annular filter screen belt 21 and the material crushed by the first crushing assembly, the second annular filter screen belt 22 is mounted on a second transmission device and driven by the second transmission device to rotate anticlockwise, the second transmission device enables the second annular filter screen belt 22 to be obliquely arranged in a left-high-right direction, and enables the second annular filter screen belt to be provided with a second upper section which is tensioned and a second lower section which is loosened and located below the second upper section, so that partial material filtered by the second upper section falls from the right end of the second upper section, and the rest material passes through the second upper section and then is gathered at the left side of the second lower section and falls through the second lower section. The second crushing assembly is configured to receive and crush material falling from the right end of the second upper section.
The material outlet belt 13 is arranged at the bottom in the shell 11 and used for outputting the screened and crushed material.
In this embodiment, material enters through the feed opening 12 and is finally carried out through the discharge belt 13. The material entering the feed opening 12 is firstly filtered by the first annular filter screen belt 21, the material with medium grain size and fine grain size directly falls into the second annular filter screen belt 22 for the next stage of filtering, and the material with coarse grain size falls into the first crushing component from the left side of the first upper section by the transmission of the first annular filter screen belt 21 for the first stage of crushing treatment. Because the first annular filter screen belt 21 is obliquely arranged with a lower left part and a higher right part, the first upper section is tensioned, and the first lower section is loosened, a net bag is naturally formed on the left side of the first lower section, and materials fall from the highest point of the first upper section, naturally slide to the left side of the first lower section after being screened by the first upper section and are gathered in the first upper section, and then fall to the second annular filter screen belt 22 after passing through the first lower section. Because the second annular filter screen belt 22 is obliquely arranged in a left-high and right-low manner, the materials screened by the first annular filter screen belt 21 and crushed by the first crushing assembly just fall on the highest point of the second annular filter screen belt 22. Therefore, the conveying distance of the materials on the first annular filter screen belt 21 and the second annular filter screen belt 22 is ensured to be prolonged as far as possible, so that enough filter time is reserved for the filter of the first annular filter screen belt 21 and the second annular filter screen belt 22, and the phenomenon of over-grinding caused by the fact that the materials fall into a crushing device in advance without effective filter due to untimely filter is avoided. The second upper section of the second annular filter screen belt 22 is tensioned, the second lower section is relaxed (i.e. the structure is the same as that of the first annular filter screen belt 21), after the materials are screened by the second annular filter screen belt 22, the materials with fine particle size naturally slide to the right side of the second lower section, and the materials with medium particle size fall from the right end of the second upper section and enter the second crushing assembly for secondary crushing.
Further, first annular filter screen area 21 clockwise rotation, second annular filter screen area 22 anticlockwise rotation, the direction of operation of filter screen area and the direction of the natural whereabouts of material are opposite promptly to the time of transporting of extension material guarantees the sieve of material on the filter screen area and strains the time, further improves the sieve and strains the effect. And because the first lower section and the second lower section are arranged loosely, the falling of the materials can improve the vibration amplitude of the first lower section and the second lower section, and further improve the screening effect.
It should be noted that the invention is not limited to only two-stage filtration and crushing, and may also be provided with three-stage or four-stage filtration and crushing according to actual needs, and the inclination direction of the next-stage filter screen belt is opposite to the inclination direction of the previous-stage filter screen belt, so as to ensure that the material filtered by the previous-stage filter screen falls on the highest point of the next-stage material. All the filter screen belts are provided with filter holes 211, and the size of the filter holes 211 on each filter screen belt is gradually reduced from top to bottom.
