Description

Technical Field

[0001] The utility model relates to the technical field of cement processing, in particular to a feeder for a limestone crushing system. Background Art

[0002] Limestone materials are prone to be adhered to a large amount of clay or impurities during blasting and loading and transportation. When limestone materials are crushed, the above-mentioned adhered soil and impurities are directly fed into the crushing chamber through the plate feeder, and will adhere to the inside of the crushing chamber, the hammer disc, and the grate plate, causing material accumulation, resulting in blockage of the crushing chamber and the discharge grate plate, thereby reducing the production capacity of the crusher. In addition, the soil and impurities adhered to the crushing chamber will cause wear of parts such as the hammer head, hammer disc, and liner, shortening the service life of the above parts, thereby increasing the cost of crushing equipment. In addition, the higher the soil content in the limestone material, the greater the impact on the crusher, especially in rainy and snowy weather, and even the crushing motor may be overloaded and tripped, seriously reducing production capacity.

[0031] In the utility model, limestone material enters the feeder housing 1 through a conveying device, a driving motor 4 drives the first screening device 2 to rotate, and another driving motor 4 drives the second screening device 3 to rotate. The first screening device 2 screens the limestone material, clay, and impurities with a smaller volume, and conveys the material with a larger volume to the second screening device 3. The second screening device 3 screens the limestone that meets the crushing requirements, and at the same time conveys the limestone that does not meet the crushing requirements to the limestone material storage area. Such an arrangement can prevent bulk clay and impurities from entering the crusher, and the clay and impurities adhere to the inside of the crushing chamber and the hammer disc and the grate plate, causing material accumulation, resulting in blockage of the crushing chamber and the discharging grate plate, and the crushing motor overload tripping. At the same time, the second screening device 3 can screen the limestone material that meets the crushing requirements, thereby preventing larger limestone materials from entering the crusher and affecting the crushing efficiency of the crusher.

[0032] The utility model has two drive motors which are arranged on the feeder housing 1 and are respectively connected to the first screening device 2 and the second screening device 3.

Specifically, the drive motor 4 drives the first active roller 21 to rotate, and the first active roller 21 drives the first driven roller 22 to rotate through the first transmission structure 23. Moreover, the gap between the first active roller 21 and the first driven roller 22 is used to screen the limestone material.

[0089] The discharging mechanism 7 includes a screening discharge port 63 opened at the bottom of the feeder housing 1 and adapted to the first screening device 2, a crushing discharge port 71 opened at the bottom of the feeder housing 1 and adapted to the second screening device 3, and a discharge port 72 arranged at the rear end of the feeder housing 1 and adapted to the second screening device 3; a discharging guide plate 73 is arranged in the feeder housing 1 and located between the crushing discharge port 71 and the discharge port 72.

[0090] This embodiment 10 provides a more preferred structure of the discharge mechanism 7 on the basis of embodiment 9, specifically: the discharge mechanism 7 includes a screening discharge port 63 opened at the bottom of the feeder housing 1 and adapted to the first screening device 2, a crushing discharge port 71 opened at the bottom of the feeder housing 1 and adapted to the second screening device 3, and a discharge port 72 provided at the rear end of the feeder housing 1 and adapted to the second screening device 3; a discharge guide plate 73 is provided in the feeder housing 1 between the crushing discharge port 71 and the discharge port 72.

[0091] The screening discharge port 63 of the utility model is arranged at the bottom of the feeder housing 1 and is adapted to the first screening device 2. The screening discharge port 63 can facilitate the discharge of the limestone material screened by the first screening device 2. The crushing discharge port 71 is arranged at the bottom of the feeder housing 1 and is adapted to the second screening device 3, so as to facilitate the limestone that meets the crushing requirements screened by the second screening device 3 to be put into the crusher. The discharge port 72 can discharge the limestone that does not meet the crushing requirements of the crusher into the feeder housing 1 under the action of the second screening device 3, thereby avoiding the accumulation of limestone in the feeder housing 1 and causing blockage.

[0092] The discharge guide plate 73 of the utility model is arranged in the feeder housing 1 and is located between the crushing discharge port 71 and the discharge port 72. The discharge guide plate 73 can guide the limestone material that does not meet the crushing requirements so that it can fall into the limestone material accumulation area.

[0093] The working principle of this utility model:

[0094] When in use, the limestone material is transported to the feeder housing 1 through the feeding port 61 by the conveyor belt, and the drive motor 4 is started. The drive motor 4 drives the first screening device 2 and the second screening device 3 to rotate respectively. When the limestone is on the first screening device 2, the first screening device 2 will screen the smaller limestone material, soil and impurities. After the screening is completed, the limestone material is transported to the second screening device 3. The second screening device 3 will put the limestone that meets the crushing requirements into the crusher through the crushing discharge port 71 for crushing, and send the limestone that does not meet the requirements to the limestone accumulation area, thereby preventing the smaller limestone material, soil, impurities and the larger limestone from entering the crusher and affecting the crushing efficiency.

[0095] The driving motor 4, conveyor belt and crusher used in the present invention are all prior art, so the structures and principles of the first motor 41, conveyor belt and crusher are not described in detail here.

[0096] Finally, it should be noted that the above embodiments are only preferred embodiments of the present invention to illustrate the technical solution of the present invention, rather than limiting it, and certainly not limiting the patent scope of the present invention; although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention; that is to say, any changes or embellishments made to the main design concept and spirit of the present invention that have no substantive significance, and the technical problems they solve are still consistent with the present invention, should be included in the protection scope of the present invention; in addition, the direct or indirect application of the technical solution of the present invention in other related technical fields is also included in the patent protection scope of the present invention.
