[0002] Zinc concentrate is generally an ore with a relatively high zinc content meeting national standards produced by processes such as crushing, ball milling, and froth flotation of lead-zinc ore or zinc-containing ore. Zinc concentrate is the main raw material for producing metallic zinc, zinc compounds, etc.

[0003] At present, zinc concentrate needs to be produced by processes such as crushing lead-zinc ore or zinc-containing ore by a crusher, ball milling, and froth flotation. The product after being crushed by the crusher needs to be transported to a vibrating screen by a conveyor for screening. The top of the screen of the existing screening device for lead-zinc ore or zinc-containing ore in zinc concentrate beneficiation often needs to bear the impact force of the material falling from the discharge end of the conveyor onto the screen, making the screen prone to deformation and damage. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an efficient screening device for zinc concentrate beneficiation, which is used to solve the problem that the top of the screen of the existing screening device often needs to bear the impact force of the material falling from the discharge end of the conveyor onto the screen, making the screen prone to deformation and damage.

[0005] To solve the above problems, the utility model provides an efficient screening device for zinc concentrate beneficiation, including a chassis and a screen frame. Two supports are respectively fixed on both sides of the screen frame. The four corners of the top of the chassis are respectively fixedly installed with the lower sides of the corresponding supports through vibrating screen springs. Two inclined support plates are fixedly installed inside the screen frame. A detachable screen is arranged on the support plates. A sliding seat is slidably connected between the two support plates. Two mounting seats are fixed inside the screen frame. A groove is formed on one side of the mounting seat. A detachable cylinder is arranged in the groove. A screen plate is fixed between the two cylinders. One side of the screen plate is fixedly installed with the sliding seat through a positioning bolt. An arc plate is arranged above the screen plate. A plurality of strip holes are formed in the arc plate.

[0006] The efficient screening device for zinc concentrate beneficiation provided by the utility model further has the following technical features:

[0007] Further, both sides of the arc plate are respectively connected with the inner wall of the screen frame through fixing bolts. The bottom of the arc plate is located above the top of the screen. A vibrating motor is fixedly installed on the lower side of the screen frame.

[0008] Further, both the screen and the screen plate are provided with screen holes, and the sizes of the screen holes on the screen and the screen holes on the screen plate are the same.

[0009] Further, an L-shaped block is fixed at the bottom of the support plate. The screen is located between the L-shaped block and the sliding seat. A pressing block is fixed on one side of the sliding seat, and the lower side of the pressing block can be in contact with the upper side of the screen.

[0010] Further, one side of the sieve frame is threadedly connected with a stud, and one end of the stud is rotatably connected to the sliding seat.

[0011] Further, a discharge plate is fixedly installed on the lower side of the support plate, and a discharge port is provided on one side of the bottom of the sieve frame.

[0012] The utility model has the following beneficial effects: The product after being crushed by the crusher is transported to the top of the device by the conveyor and then falls. Through the arrangement of the arc plate, it plays a role in guiding and buffering, so that part of the crushed material falls onto the sieve plate through the strip holes and is screened by the sieve plate, and another part of the material falls onto the sieve mesh after being buffered by the arc plate and is screened by the sieve mesh. The screened small-particle material passes through the sieve mesh or the sieve plate and then falls into the sieve frame and is discharged through the discharge port, while the large-particle material can slide along the sieve mesh to the bottom of the sieve mesh and be discharged. The sieve plate plays a role in supporting and screening the falling material, avoiding the large impact of the material on the sieve mesh and preventing the sieve mesh from being damaged, and the sieve plate is convenient for disassembly and replacement.

Two supports 3 are respectively fixed on both sides of the screen frame 2. The four corners of the top of the chassis 1 are respectively fixedly installed with vibrating screen springs on the lower sides of the corresponding supports 3. Two inclined support plates 4 are fixedly installed inside the screen frame 2. A detachable screen mesh 5 is arranged on the support plates 4. A sliding seat 6 is slidably connected between the two support plates 4. Two mounting seats 7 are fixedly installed inside the screen frame 2. A groove is formed on one side of the mounting seat 7. A detachable cylinder 8 is arranged in the groove. A screen plate 9 is fixed between the two cylinders 8. One side of the screen plate 9 is fixedly installed with the sliding seat 6 through a positioning bolt. By unscrewing the positioning bolt, it is convenient to disassemble the screen plate 9 from the groove of the mounting seat 7, and then it is convenient to clean or replace the screen plate 9. An arc plate 10 is arranged above the screen plate 9. A plurality of strip holes are formed on the arc plate 10. The products after being crushed by a crusher are transported to the top of the device by a conveyor and then fall. Through the arrangement of the arc plate 10, it plays a role of guiding and buffering, so that some of the crushed materials fall onto the screen plate 9 through the strip holes and are screened by the screen plate 9, and the other part of the materials fall onto the screen mesh 5 after being buffered by the arc plate 10 and are screened by the screen mesh 5. The screened small-particle materials pass through the screen mesh 5 or the screen plate 9 and then fall into the inside of the screen frame 2 and are discharged through the discharge port 15, while the large-particle materials can slide along the screen mesh 5 to the bottom of the screen mesh 5 and be discharged. The screen plate 9 plays a role of supporting and screening the falling materials, avoiding a large impact on the screen mesh 5 by the materials. The screen plate 9 is convenient to disassemble and replace.
