Description

Technical Field

[0001] The utility model relates to the technical field of crushers, in particular to a particle material crusher. Background Art

[0002] The grinder can be used for micro-grinding of granular raw materials, such as corn, wheat, rice, beans and various types of dried potatoes. It is also suitable for micro-grinding and use in the pharmaceutical, alcohol and other industries.

[0003] The pulverizer consists of a housing and a rotating shaft. The shaft rotates within the housing, and hammers are mounted on its outer wall to strike the pellets. A feed inlet is located at the top of the housing, and a discharge outlet is located on one side of the housing, with a safety door at the outlet. Rotating the shaft causes the hammers to strike the pellets. Once the pellets are crushed, the safety door opens and the powder is discharged.

[0004] After use, the crusher requires regular cleaning of the interior to prevent the accumulation of old material. Traditionally, workers open the safety door and flush the interior of the crusher with a hose. However, the crusher contains rotating shafts, hammers, and other mechanical components, which can easily cause the cleaning fluid to splash onto workers, making cleaning inconvenient.

[0019] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0020] The present application discloses a granular material crusher, referring to Figure 1 、 Figure 2 and Figure 3 , comprising a shell 1 and a rotating shaft 2, the rotating shaft 2 is rotatably arranged in the shell 1, and the axis of the rotating shaft 2 is horizontal. A plurality of hammers 21 for hitting the granular material are installed on the outer wall of the rotating shaft 2, and a feed port is provided at the top of the shell 1, and a cover plate 3 is installed at the feed port. A mounting plate 4 for extending into the interior of the shell 1 is installed on the cover plate 3, and a plurality of nozzles 41 for spraying cleaning liquid are installed on the mounting plate 4. The nozzles 41 are connected to a water supply tank (not shown in the figure) through a soft water pipe, and the water supply tank has a built-in water pump. A discharge port is provided on one side of the shell 1, and a safety door 5 is installed at the discharge port. A first driving member 6 for driving the rotating shaft 2 to rotate is installed on the outer wall of the shell 1.

[0021] In this embodiment of the present application, when cleaning the interior of the housing 1, a worker installs the cover plate 3 at the feed port of the housing 1, inserts the mounting plate 4 and nozzle 41 into the interior of the housing 1, and then activates the water pump to spray cleaning fluid into the interior of the housing 1 through the nozzle 41. After the interior of the housing 1 is completely flushed, the safety door 5 is opened to drain the cleaning fluid. This method prevents the cleaning fluid from splashing onto the worker, making cleaning the interior of the grinder more convenient.

[0022] Furthermore, the mounting plate 4 slides vertically on the cover plate 3. A second actuator 7 is mounted on the cover plate 3 to drive the movement of the cover plate 3. The second actuator 7 comprises a cylinder 71 and a movable plate 72. Cylinder 71 is vertically mounted on top of the cover plate 3. The piston rod of cylinder 71 moves through the cover plate 3 and is bolted to the movable plate 72. The mounting plate 4 is mounted on the side of the movable plate 72 facing away from the cover plate 3. Both the cover plate 3 and the movable plate 72 have through-holes for the water supply pipe to pass through.

[0023] In the embodiment of the present application, after the cover plate 3 is installed at the feed port of the shell 1, the movable plate 72 can be driven downward by the cylinder 71, and the nozzle 41 moves downward therewith, which can further improve the cleaning effect on the inside of the shell 1.

[0024] Because the water pipe moves with the movable plate 72, it will wear and tear with the angular friction of the through hole. In order to solve this problem, the through hole is embedded with a protective cover 8 for movable contact with the water pipe outer wall.

[0025] In the embodiment of the present application, the protective cover 8 is made of PVC material, and both ends of the inner wall of the protective cover 8 are provided with arc-shaped chamfers. The protective cover 8 can reduce the wear and tear on the water pipe, thereby increasing the service life of the water pipe.

[0026] Furthermore, the mounting plate 4 is rotatably arranged on the movable plate 72 , and a third driving member 9 for driving the mounting plate 4 to rotate is provided on the movable plate 72 , and the axis of the rotating shaft of the mounting plate 4 is horizontal.

[0027] In this embodiment of the present application, the third drive member 9 can be used to drive the mounting plate 4 to rotate, thereby increasing the flushing range of the nozzle 41 and improving the flushing effect of the nozzle 41. During the rotation of the mounting plate 4, the rotation angle of the mounting plate 4 must be controlled to prevent the nozzle 41 from flipping over and causing the cleaning liquid to flow onto the movable plate 72 and cover plate 3. This also prevents the water pipe from bending excessively. Both the first drive member 6 and the third drive member 9 can utilize drive motors to drive the corresponding components.

[0028] In order to further increase the flushing range of the nozzle 41, the nozzle 41 adopts a rotating nozzle.

[0029] In the embodiment of the present application, the cleaning liquid can be transported to the rotating nozzle by starting the water pump. Under the water pressure of the cleaning liquid, the rotating nozzle can rotate by itself while spraying the cleaning liquid, further improving the cleaning effect on the inside of the shell 1.

[0030] Furthermore, a plurality of guide rods 721 are vertically welded to the movable plate 72. The end of the guide rod 721 away from the movable plate 72 is movable through the cover plate 3 and welded with a stopper 722. A spring 10 is sleeved on the outer wall of the guide rod 721 on the cover plate 3 to drive the stopper 722 away from the cover plate 3.

[0031] In the embodiment of the present application, when cleaning the interior of housing 1, the piston rod of cylinder 71 extends out of the cylinder body and overcomes the elastic force of spring 10 to drive movable plate 72 downward. After cleaning the interior of housing 1, the piston rod retracts into the cylinder body and drives movable plate 72 upward. During this process, the spring 10, under its elastic force, cooperates with cylinder 71 to drive movable plate 72 upward. In addition, when the piston rod retracts into the cylinder body, spring 10 remains in a compressed state, which allows spring 10 to share some of the weight of movable plate 72, mounting plate 4, and nozzle 41, thereby reducing the load on cylinder 71.

[0032] Furthermore, the cover plate 3 is detachably connected to the opening of the housing 1. A protrusion is integrally fixed to the edge of the opening. The cover plate 3 is provided with a groove for accommodating the protrusion. A plurality of stoppers 20 are movably provided along the circumference of the groove edge for contacting the bottom of the protrusion to prevent the cover plate 3 from separating from the housing 1. One end of the stopper 20 is frictionally rotated on the cover plate 3, and the other end of the stopper 20 is in movable contact with the protrusion.

[0033] In the embodiment of the present application, after the cover plate 3 is installed at the opening of the shell 1, the limit plate 20 is rotated and one end of the limit plate 20 is brought into contact with the protrusion, so as to prevent the cover plate 3 from separating from the shell 1, thereby improving the installation stability of the cover plate 3 on the shell 1.

[0034] The working principle of a pellet mill according to the embodiment of the present application is as follows: when cleaning the interior of housing 1, a worker installs cover plate 3 at the feed inlet of housing 1, inserts mounting plate 4 and nozzle 41 into housing 1, and then activates the water pump to spray cleaning fluid into housing 1 through nozzle 41. After flushing the interior of housing 1, safety door 5 is opened to drain the cleaning fluid. This method prevents splashing of cleaning fluid onto workers, making cleaning the interior of the mill more convenient.

Therefore, the appended claims are intended to be interpreted as encompassing the preferred embodiments and all changes and modifications that fall within the scope of the present invention.
