The outer edge of the auxiliary screen frame is of a trapezoidal structure, and the spoke screen frame is provided with bolt holes.
The outer edge of the auxiliary screen frame is matched with the middle frame hole, and the main screen arc-shaped frame forming the middle frame hole and the main screen middle frame are provided with mounting holes corresponding to the bolt holes in the screen frame.
The arc-shaped frame of the main screen and the arc-shaped frame of the auxiliary screen are arc-shaped steel plates or flat steel.
The side frames of the main screen, the middle frame of the main screen and the side frames of the auxiliary screen are rectangular steel plates or flat steels.
Compared with the prior art, the arc-shaped sieve plate provided by the utility model has the advantages that the structure is simple, the manufacturing cost is low, and the arc-shaped sieve plate is detachably arranged in the main sieve frame, so that the arc-shaped sieve plate is convenient to replace, maintain and clean; the middle part of the auxiliary screen is protruded, so that the impact resistance of the auxiliary screen to a fed medium is improved, and the durability of the arc-shaped sieve plate is enhanced; the detachable auxiliary screen realizes local replacement, greatly saves the production cost of enterprises, and realizes considerable economic benefit for the enterprises.

Detailed Description
In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The present invention will be described in detail with reference to the accompanying drawings, in an embodiment of the present invention, an arc-shaped screen plate includes a curved main screen and a curved auxiliary screen, the main screen includes a main screen 11 and a main screen frame 12, the main screen frame 12 is composed of a main screen arc frame 121, a main screen side frame 122 and a main screen middle frame 123 which are symmetrical to each other, two left and right frame holes composed of the main screen arc frame 121, the main screen side frame 122 and the main screen middle frame 123 which are symmetrical to each other are formed, and a middle frame hole composed of the main screen arc frame 121 and the main screen middle frame 123 which are symmetrical to each other is formed; the main screen 11 is fixed in the frame holes at the left and right sides of the main screen frame 12; the auxiliary screen comprises an auxiliary screen 21 and an auxiliary screen frame 22, the auxiliary screen frame 22 consists of an auxiliary screen arc-shaped frame 221 and an auxiliary screen side frame 222 which are symmetrical to each other, and the auxiliary screen 21 is fixed in the auxiliary screen frame 22; the middle part of the auxiliary screen 21 protrudes towards the arc concave surface of the arc-shaped screen plate, and the thickness of the screen at the protruding part is twice of that of the other parts of the auxiliary screen 21. The outer edge of the auxiliary screen frame 22 is of a trapezoidal structure, and the amplitude screen frame 22 is provided with bolt holes; the outer edge of the auxiliary screen frame 22 is matched with the middle frame hole, and mounting holes corresponding to the bolt holes in the screen frame 22 are formed in the main screen arc-shaped frame 121 and the main screen middle frame 123 which form the middle frame hole.
The auxiliary sieve and the main sieve are made of the same material, and the main screen 11 and the auxiliary screen 21 are made of stainless steel; because the auxiliary screen 21 is arranged at the position where the fed media are washed away, the washing force of the media can be effectively resisted, and the shock resistance of the auxiliary screen 21 is enhanced due to the arrangement of the convex structure in the middle of the auxiliary screen 21. When the secondary screen 21 is damaged due to the fact that the scouring force of the medium is too large, the secondary screen is detached and replaced by detaching bolts connected between the secondary screen frame 22 and the main screen frame 12, and therefore the integrity of the main screen 11 is guaranteed.
The present invention has been described above with reference to the accompanying drawings, but the technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
