Description

Technical Field

[0001] The utility model relates to the technical field of crushing equipment, in particular to a raw material crusher for granulation. Background Art

[0002] The raw material crusher is one of the essential equipment used in the raw material granulation process, which can crush the granulated raw materials to facilitate the subsequent granulation process. Most of the existing raw material crushers do not have a separation mechanism. The granulated raw materials are directly discharged from the outside of the machine body after a crushing operation by the raw material crusher, resulting in the need to collect and screen the crushed raw materials again, and then pour the unqualified large particle crushed materials screened out back into the raw material crusher for crushing to obtain qualified quality raw material crushed materials, making the crushing of granulation raw materials more cumbersome, time-consuming and labor-intensive, and inconvenient to use.

[0003] Application No. 202222768221.6 discloses a raw material crusher for granulation, which can screen the crushed uneven coarse and fine crushed materials through a separation mechanism, so that the crushed materials with larger particle diameters remain on the filter screen, and the qualified crushed materials are directly discharged and collected. At the same time, the circular frame with the filter screen is convenient to be directly extracted, so that the crushed materials with larger particle diameters can be quickly poured back into the equipment for secondary crushing, which simplifies the operation steps and improves the convenience of use. Although the raw material crusher for granulation can meet daily use, it has shortcomings. The main problem is that the circular frame with the filter screen is convenient to be directly extracted. When performing secondary crushing, it is necessary to shut down or temporarily stop feeding, which affects work efficiency. When the separation mechanism is used, the filter screen will have a clogging problem, and the extraction and cleaning frequency can only be increased, which is bound to have an adverse effect on production efficiency.

[0023] In order to have a clearer understanding of the technical features, purposes and effects of the present utility model, the specific implementation methods of the present utility model are now described in detail with reference to the accompanying drawings.

[0024] like Figure 1-6 As shown, the raw material crusher for granulation comprises a crushing bin 1, a feed port 2 arranged at the upper part of the crushing bin 1, a discharge port 3 arranged at the lower part of the crushing bin 1, a crushing roller pair 4 arranged in the crushing bin 1, and a filtering mechanism 5 arranged at the lower part of the crushing roller pair 4;

[0025] The filtering mechanism 5 includes a driving roller 51 arranged in the crushing bin 1, an annular filter screen 52 wound around the driving roller 51, a driving mechanism for driving the driving roller 51 to rotate, a cleaning brush roller 54 arranged on the inner side of the annular filter screen 52, and a storage bin 55 located outside the crushing bin 1 on one side of the filtering mechanism 5. The storage bin 55 includes a bin body and an openable and closable discharge port 551 arranged on the bin body.

[0026] The raw material crusher for granulation has an annular filter screen 52 wound around the driving roller 51, and cooperates with a cleaning brush roller 54 and a storage bin 55, so that when large particles on the annular filter screen 52 accumulate to a certain extent or the annular filter screen 52 needs to be cleaned, the driving roller 51 is driven to rotate so that the large particles on the annular filter screen 52 are sent to the storage bin 55 on one side, and the annular filter screen 52 can be effectively cleaned under the action of the cleaning brush roller 54. The utility model does not need to stop the machine or suspend feeding when the filter screen is blocked during discharging and cleaning, which can effectively improve production efficiency and effectively prevent blockage.

[0027] In this embodiment, the transmission roller 51 includes a rotating shaft and toothed rings at both ends of the rotating shaft, and transmission toothed belts are arranged on the inner walls of both sides of the annular filter 52, and the transmission toothed belts are connected to the toothed rings. Of course, in some other embodiments, the transmission structure can be directly matched with the transmission roller 51 and the ring, such as drawing on the connection method of the conventional conveyor belt, and the annular filter 52 can be driven by the transmission roller 51 to rotate after the driving mechanism is turned on.

[0028] The cleaning brush roller 54 includes a brush roller shaft, bristles 541 arranged on the brush roller shaft, and a driving member arranged at one end of the brush roller shaft for driving the brush roller shaft to rotate. The driving member can be independently arranged, such as a motor, etc., and of course, it can also be connected to the driving mechanism through a transmission member. When the driving roller 51 is in motion, the cleaning brush roller 54 cleans the annular filter 52. When the driving roller 51 stops, the brush roller shaft can be in a stopped state.

[0029] A cleaning baffle 6 and a guide plate 7 are provided below the annular filter 52. The guide plate 7 extends to the outside of the crushing bin 1 and extends into the storage bin 55. The cleaning baffle 6 is used to prevent large particles from being carried during the rotation of the annular filter 52. The filter plate can perform secondary cleaning on the annular filter 52. Preferably, a material-blocking brush 61 is provided at the upper end of the cleaning baffle 6. The blocked large particles are sent into the storage bin 55 through the guide plate 7.

[0030] An inclined baffle 11 is provided on the inner wall of the crushing bin 1, and the bottom of the inclined baffle 11 is inclined toward the center of the crushing bin 1. The setting of the inclined baffle 11 can make the material relatively concentrated and will not fall into the junction of the annular filter 52 and the crushing bin 1, and can prevent the material from falling directly into the guide plate 7.

[0031] Finally, it should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0032] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
