Description

Technical Field

[0001] This utility model relates to the field of screening equipment, specifically a screening equipment with dust prevention effect. Background Technology

[0002] The process of separating bulk materials into different particle sizes by passing them through one or more screens is called screening. A screening machine is a vibrating screening device that uses the relative motion between the bulk material and the screen surface to allow some particles to pass through the screen holes, separating materials such as sand, gravel, and crushed stone into different grades according to particle size. The screening process is generally continuous. After the raw material is fed onto the screening machine (referred to as the screen), materials smaller than the screen hole size pass through the screen holes and are called undersize products; materials larger than the screen hole size are continuously discharged from the screen surface and are called oversize products. Existing screening machines generally have their screens directly exposed, thus generating a large amount of dust during vibrating screening. Therefore, we have proposed a screening device with dust-preventing effects. Utility Model Content

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides a screening device with dust-prevention effect, which has the following beneficial effects:

[0014] 1. This dust-proof screening equipment works by pouring the material into the box through the feed inlet when screening is required.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 A dust-preventing screening device includes a housing 1, one side of which is open. A screen 10 is installed inside the housing 1, positioned at an angle. A hinged door 2 is connected to the top of the open side of the housing 1. A storage drawer 5 is located at the bottom of the housing 1, corresponding vertically to the screen 10. A vibration component is installed on the inner wall of the housing 1, and a connecting component is installed at the corner of the inner wall of the housing 1 corresponding to the screen 10. The connecting component is connected to the screen 10. A feed inlet 6 is located at the top of the housing 1. When screening is required, the material is poured into the housing 1 through the feed inlet 6 and falls onto the screen 10. The vibration component is activated, causing the screen 10 to vibrate. The screened material falls into the storage drawer 5. After screening, the door 2 is opened, and the unscreened material is removed from the screen 10. This device effectively keeps the screening process inside the housing 1, preventing dust from being stirred up.

[0024] Furthermore, two inclined rubber blocks 8 are fixedly installed on the inner walls of both sides of the feed inlet 6. When the material is poured into the feed inlet 6, the inclined rubber blocks 8 will tilt and deform. When the material is stopped being poured in, the two inclined rubber blocks 8 will return to their original positions and their closest ends will fit together to keep the feed inlet 6 sealed and prevent dust from overflowing.

[0025] Furthermore, side grooves 3 are provided on the inner walls of both sides of the box 1, and side protrusions 4 are integrally formed on the storage drawer 5 corresponding to the side grooves 3. When screening, the screened material will fall into the interior of the storage drawer 5. The material can be taken out by pulling out the storage drawer 5, which is simple and convenient.

[0026] Furthermore, handles are fixedly installed on the outside of both the hinged door 2 and the storage drawer 5.

[0027] Furthermore, the vibration assembly includes a motor 7 and a cam 9. The motor 7 is fixedly installed on the side of the housing 1, and the output shaft of the motor 7 extends into the interior of the housing 1. The cam 9 is fixedly installed on the output shaft of the motor 7. The cam 9 is located below the screen 10. When screening is required, the motor 7 starts and drives the cam 9 to rotate. Then, when the protruding end of the cam 9 contacts the screen 10, it will push the screen 10 upward. Then the connecting assembly is stretched. When the protruding end of the cam 9 is no longer in contact with the screen 10, the connecting assembly is pulled back, driving the screen 10 to reset. Then the screen 10 reciprocates in this way, generating vibration and performing screening.

[0028] Furthermore, the connecting assembly includes a fixed rectangular block 12 and an insert rod 11. The fixed rectangular block 12 is fixedly installed on the inner wall of the housing 1, and the insert rod 11 is movably inserted into the fixed rectangular block 12. One end of the insert rod 11 is fixedly connected to the bottom of the screen 10. A limit block 13 is fixedly installed on the insert rod 11. A tension spring 14 is provided between the limit block 13 and the fixed rectangular block 12. When the protruding end of the cam 9 contacts the screen 10, it will push the screen 10 upward. Then the insert rod 11 moves upward, and the tension spring 14 is stretched. When the protruding end of the cam 9 is no longer in contact with the screen 10, the tension spring 14 resets and pulls the limit block 13, causing the insert rod 11 to pull back.

[0029] Working principle: When materials need to be screened, the materials are poured into the inside of the box 1 through the feed port 6 and then fall onto the screen 10. The motor 7 starts and drives the cam 9 to rotate. When the protruding end of the cam 9 contacts the screen 10, it will push the screen 10 upward. Then the insertion rod 11 moves upward, and the tension spring 14 is stretched. When the protruding end of the cam 9 is no longer in contact with the screen 10, the tension spring 14 returns to its original position and pulls the limit block 13, causing the insertion rod 11 to pull back. Then the screen 10 moves back and forth in this way, generating vibration and performing screening.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
