All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] Embodiment:

[0029] Please refer to Figures 1-3 , this embodiment provides a ball screening device, which includes a ball screening box 1. A fixed plate 11 is fixedly connected to the bottom end inside the ball screening box 1. A cleaning chamber and a ball screening chamber are formed inside the ball screening box 1 through the fixed plate 11. A ball screening mechanism 4 is installed inside the ball screening box 1. The ball screening mechanism 4 is placed inside the cleaning chamber and the ball screening chamber. The ball screening mechanism 4 is used to screen the steel balls of the ball mill into different size specifications. A cleaning unit is arranged in the cleaning chamber, and the cleaning unit is used to clean the steel balls of the ball mill to be screened. A ball guiding unit is arranged in the ball screening chamber, and the ball guiding unit is used to classify and guide the steel balls of the ball mill after screening. A ball inlet hopper 5 is fixedly connected to the top of the ball screening box 1.

[0030] As an implementation manner of this embodiment, as shown in Figure 2 and Figure 3 , the ball screening mechanism 4 includes two ball screening rods 41 fixedly connected to the inside of the ball screening box 1. The ball screening rods 41 are divided into parallel rod segments 411 and expanding rod segments 412. The parallel rod segments 411 of the two ball screening rods 41 are placed in the cleaning chamber and the distance between them is equal. The expanding rod segments 412 of the two ball screening rods 41 are placed in the ball screening chamber and the distance between them gradually increases. The ball screening rods 41 are inclined. The ball screening rods 41 are inclined downward along the parallel rod segments 411 towards the expanding rod segments 412. A ball inlet pipe is fixedly connected to the bottom of the ball inlet hopper 5. The ball inlet pipe can accommodate one steel ball of the ball mill. The ball inlet pipe is located above the parallel rod segments 411 of the ball screening rods 41. By placing the steel balls of the ball mill into the ball inlet hopper 5 and transporting them to the ball screening rods 41 through the ball inlet pipe, the steel balls of the ball mill roll between the two ball screening rods 41. By rolling on the parallel rod segments 411 of the ball screening rods 41, the impurities on their surfaces are cleaned by the cleaning unit. After being cleaned, the steel balls of the ball mill move to the expanding rod segments 412 of the ball screening rods 41. Due to the gradually increasing distance between them, the steel balls of different diameters fall from different positions of the ball screening rods 41, and the ball guiding unit classifies and conveys and collects the steel balls of different specifications.

[0031] In this embodiment, as shown in Figure 3As shown in the figure, anti - detachment plates 42 are fixedly connected to the outer sides of both the parallel rod section 411 and the expanding rod section 412 of the screening ball rod 41. The anti - detachment plates 42 are of arc - shaped structure and are arranged in multiple groups along the length direction of the screening ball rod 41. By setting the anti - detachment plates 42, the steel balls of the ball mill moving on the screening ball rod 41 can be blocked, preventing the steel balls of the ball mill from detaching from the screening ball rod 41.

[0032] As an implementation manner of this embodiment, as Figure 1 and Figure 2 shown in the figure, the bottom of the screening ball bin is designed to be open. The ball guiding unit includes a ball guiding plate 12 fixedly connected to the bottom of the screening ball bin and arranged obliquely. The ball guiding plate 12 is divided into multiple ball guiding cavities by partitions. The width of the ball guiding cavity gradually increases from the parallel rod section 411 to the expanding rod section 412. Support rods 2 are fixedly connected to both sides of the screening ball box 1. The bottom of the support rods 2 is fixedly connected to the same bottom plate 3. A collection box 13 is installed on the top of the bottom plate 3. The collection box 13 corresponds to the position of the ball guiding plate 12. A plurality of collection cavities are provided in the collection box 13. The number of collection cavities is the same as that of the ball guiding cavities and they correspond one by one. By setting the support rods 2 and the bottom plate 3, the screening ball box 1 is stably supported. After screening by the screening mechanism 4, the steel balls of the ball mill with different diameter specifications fall onto the ball guiding plate 12 and then into the corresponding ball guiding cavities, and are transported to the collection box 13 through the ball guiding plate 12 and fall into the corresponding collection cavities, realizing the classified screening process of the steel balls of the ball mill. The operation is convenient and the screening efficiency is high.

[0033] As an implementation manner of this embodiment, as Figure 1 and Figure 2 shown in the figure, the cleaning unit includes a cleaning water tank 7 installed on the top of the bottom plate 3, a water pump 8 installed on the outer wall of the screening ball box 1, and a cleaning spray head 9 installed at the top end inside the cleaning bin. The water inlet of the water pump 8 is connected to the cleaning water tank 7 through a water inlet pipe, and the water outlet of the water pump 8 is connected to the cleaning spray head 9 through a water delivery pipe. A plurality of cleaning spray heads 9 are provided and are located above the parallel rod section 411 of the screening ball rod 41. By the operation of the water pump 8, the cleaning liquid in the cleaning water tank 7 is transported to the cleaning spray head 9 and sprayed out by the cleaning spray head 9 to clean the steel balls of the ball mill moving on the parallel rod section 411 of the screening ball rod 41, effectively removing the impurities on their surfaces, so that the screened steel balls of the ball mill can be quickly put into use.

[0034] In this embodiment, as Figure 2 shown in the figure, a drain port is provided between the cleaning bin and the cleaning water tank 7. A filter screen 10 is installed at the drain port. The filter screen 10 is used to filter the impurities in the cleaning liquid. The filtered cleaning liquid can be recycled back into the cleaning water tank 7, making the cleaning liquid recycled and saving resources. A maintenance door 6 is hingedly installed at the position of the filter screen 10 on one side of the screening ball box 1. By setting the maintenance door 6, it is convenient to clean the filter screen 10.

[0035] Working principle: Place the steel balls of the ball mill into the ball inlet hopper 5, and convey them to the ball screening rods 41 through the ball inlet pipe, so that the steel balls of the ball mill roll between the two ball screening rods 41. The steel balls of the ball mill roll on the parallel rod segments 411 of the ball screening rods 41. The water pump 8 works to convey the cleaning liquid in the cleaning water tank 7 into the cleaning nozzle 9, and the cleaning liquid is sprayed out through the cleaning nozzle 9 to clean the steel balls of the ball mill moving on the parallel rod segments 411 of the ball screening rods 41, effectively removing the impurities on their surfaces. After being cleaned, the steel balls of the ball mill move to the expanding rod segments 412 of the ball screening rods 41. As the distance between the expanding rod segments 412 gradually increases, the steel balls of the ball mill with different diameters fall from different positions of the ball screening rods 41, so that the steel balls of the ball mill with different diameter specifications fall onto the ball guiding plate 12 and into the corresponding ball guiding cavities, and are conveyed to the collection box 13 through the ball guiding plate 12 and fall into the corresponding collection cavities, realizing the classification and screening treatment of the steel balls of the ball mill. The operation is convenient and the screening efficiency is high.

[0036] The above embodiments are the preferred implementation schemes of the present utility model. In addition, the present utility model can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present utility model.
