The filter screen is a cylindrical filter screen with an opening at one end. The filter screen is sleeved on the outside of the first frame through the opening. The second frame is located on the outside of the filter screen, and the second frame is threadedly connected to the first frame.

[0007] Furthermore, the first frame includes an annular connecting sleeve.

[0008] Furthermore, a plurality of first reinforcing rods for supporting the filter screen are fixedly connected to the top of the connecting sleeve.

[0009] Furthermore, a plurality of the first reinforcing rods are evenly distributed on the top of the connecting sleeve, and ends of the plurality of the first reinforcing rods away from the connecting sleeve are connected to each other.

[0010] Furthermore, the second frame includes a connecting ring sleeved on the outside of the connecting sleeve.

[0011] Furthermore, the inner side of the connecting ring and the outer side of the connecting sleeve are both provided with mutually matching threads.

[0012] Furthermore, the connecting sleeve and the connecting ring are connected to each other via threads.

[0013] Furthermore, a plurality of evenly distributed second reinforcing rods are fixedly mounted on the top of the connecting ring.

[0014] Furthermore, a plurality of the second reinforcing rods are connected to each other at one end away from the connecting ring.

[0015] Furthermore, the first reinforcement rod and the second reinforcement rod are both L-shaped reinforcement rods.

[0016] The beneficial technical effects of the present invention are as follows: according to the discharge screen for a sand mill of the present invention, the filter screen can be clamped between the first frame and the second frame through the threaded connection, and the second frame can be rotated to remove it from the outside of the first frame during use, thereby facilitating the removal of the filter screen on the outside of the first frame, cleaning or replacing the filter screen, and making it more convenient to use. At the same time, the arrangement of the first frame and the second frame can improve the supporting strength of the filter screen. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is described in further detail below with reference to embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0025] like Figures 1-6 As shown, the discharge screen for the sand mill provided in this embodiment includes a first frame 1 and a second frame 3, and a filter screen 2 installed between the first frame 1 and the second frame 3. The filter screen 2 is a cylindrical filter screen 2 with an opening at one end. The filter screen 2 is sleeved on the outside of the first frame 1 through the opening. The second frame 3 is located on the outside of the filter screen 2, and the second frame 3 is threadedly connected to the first frame 1. The filter screen 2 can be clamped between the first frame 1 and the second frame 3 by the threaded connection, and the second frame 3 can be rotated to remove it from the outside of the first frame 1 during use, thereby facilitating the removal of the filter screen 2 on the outside of the first frame 1, cleaning or replacing the filter screen 2, and making it more convenient to use. At the same time, the arrangement of the first frame 1 and the second frame 3 can improve the support strength of the filter screen 2.

[0026] Filter screen 2. A discharge screen for a sand mill according to the first frame 1 of claim 1, the first frame 1 including an annular connecting sleeve 101, the second frame 3 including a connecting ring 301 sleeved on the outside of the connecting sleeve 101, the inner side of the connecting ring 301 and the outer side of the connecting sleeve 101 are provided with mutually matching threads, the connecting sleeve 101 and the connecting ring 301 are connected to each other through threads, the setting of the threads 303 can facilitate the connection between the connecting sleeve 101 and the connecting ring 301, and the setting of the limit bar 103 can support and limit the connecting ring 301 during use.

[0027] The top of the connecting sleeve 101 is fixedly connected with a plurality of first reinforcing rods 102 for supporting the filter screen 2. The plurality of first reinforcing rods 102 are evenly distributed on the top of the connecting sleeve 101, and the plurality of first reinforcing rods 102 are interconnected at one end away from the connecting sleeve 101. The top of the connecting ring 301 is fixedly installed with a plurality of evenly distributed second reinforcing rods 302, and the plurality of second reinforcing rods 302 are interconnected at one end away from the connecting ring 301.
