Description

Technical Field

[0001] The utility model belongs to the technical field of vibrating feeders and relates to a sealing device for a vibrating feeder. Background Art

[0002] Vibrating feeder is a device used for conveying, feeding and discharging granular materials, commonly found in docks, mines, building materials, chemicals, metallurgy and other industries. It transports materials to the desired location or equipment by vibration.

[0003] During the feeding process of the vibrating feeder, granular materials or dust are likely to overflow from the edge of the feeder. In order to reduce the impact of dust on the surrounding environment, the vibrating feeder needs to be sealed.

[0004] In industrial production, feeders are generally sealed with a single-layer soft connection. This type of seal is generally installed using bolts and pressure plates. The structure is complex and replacement is time-consuming and labor-intensive. In addition, when granular materials frequently rush outward, the soft seal structure can easily be broken, resulting in loss of sealing effect.

[0005] How to improve the sealing performance of vibrating feeder is an urgent problem to be solved. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a vibrating feeder sealing device with scientific and reasonable structure design, time-saving and labor-saving installation, long service life, good sealing effect and easy implementation.

[0007] The utility model solves the technical problem by adopting the following technical solutions:

[0008] A vibrating feeder sealing device, characterized in that it includes a primary sealing mechanism and a secondary sealing mechanism disposed outside the primary sealing mechanism, wherein the primary sealing mechanism includes a bracket, a sealing plate, a pressure plate, and a clamp, wherein sealing plates are mounted on both sides of the outer wall of the vibrating feeder hopper via the bracket, the sealing plates extending toward the inner side of the hopper and abutting against the outer wall of the chute, the pressure plate being pressed onto the sealing plates, and a clamp being mounted on the outer side of the sealing plates and clamped to the pressure plate and the bracket;

[0009] The secondary sealing mechanism includes a mounting plate, an upper U-shaped groove, a lower U-shaped groove, an anti-overflow skirt and a top screw. A mounting plate is horizontally installed at the lower part of the upper bracket of the vibrating feeder hopper. The lower U-shaped groove is installed on the mounting plate with its opening facing upward. An upper U-shaped groove with its opening facing outward is installed on the outer wall of the chute. An anti-overflow skirt is installed between the upper U-shaped groove and the lower U-shaped groove through a top screw.

[0010] Moreover, the bracket is an inverted L-shaped structure, the vertical portion of the L-shaped structure is installed on the outer wall of the vibrating feeder hopper, and the upper end surface of the horizontal portion of the L-shaped structure is flush with the upper end surface of the vibrating feeder hopper.

[0011] Moreover, the clamp includes a horizontally arranged U-shaped groove and a top screw. The U-shaped groove is clamped on the horizontal part of the pressure plate and the bracket. A top screw hole is provided on the upper end groove wall of the U-shaped groove. A top screw that is connected to the pressure plate is threaded in the top screw hole.

[0012] The advantages and positive effects of the utility model are:

[0013] The sealing device of the vibrating feeder, the sealing plate, the pressure plate and the clamp form a primary sealing mechanism between the chute and the vibrating feeder hopper, which can effectively prevent the overflow of granular materials and dust;

[0014] The upper and lower U-shaped grooves and overflow-proof skirt form a secondary sealing mechanism between the chute and the vibrating feeder hopper, which can provide a secondary seal for dust overflow from the primary sealing mechanism, improving sealing performance. The sealing structure of this utility model is fixed with a screw structure, which can be quickly installed and removed, improving maintenance efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] 1-chute; 2-hopper; 3-upper U-shaped groove; 4-top screw; 5-anti-overflow skirt; 6-clamp; 7-pressing plate; 8-sealing plate; 9-bracket; 10-lower U-shaped groove; 11-mounting plate. DETAILED DESCRIPTION

[0018] The following is a further description of the embodiments of the present invention with reference to the accompanying drawings:

[0019] A sealing device for a vibrating feeder is installed between a hopper 2 and a chute 1 of the vibrating feeder to prevent granular materials from overflowing from between the hopper and the chute of the vibrating feeder.

[0020] A bracket 9 is installed on the outside of the vertical wall of the vibrating feeder hopper. The bracket is an inverted L-shaped structure. The vertical portion of the L-shaped structure is installed on the outer wall of the vibrating feeder hopper, and the upper end surface of the horizontal portion of the L-shaped structure is flush with the upper end surface of the vibrating feeder hopper. A sealing plate 8 is installed above the bracket, and a pressure plate 7 is installed above the sealing plate. The sealing plate and pressure plate are fixed to the bracket via the jackscrew 4 on the clamp 6.

[0021] An upper U-shaped groove 3 is provided on the outer wall of the chute, a mounting plate 11 is provided on the vibrating feeder hopper, a lower U-shaped groove 10 with an upward opening is installed on the mounting plate, and an anti-overflow skirt plate 5 is provided between the upper U-shaped groove and the lower U-shaped groove.

[0022] Using this technical solution, the sealing plate, pressure plate, and clamp form a primary seal between the chute and the vibrating feeder hopper. The sealing plate is a rubber sheet that fits tightly against the chute's outer wall and is secured from above by the pressure plate and clamp. This prevents overflowing particulate matter from dislodging the sealing plate and effectively suppresses dust generated during the feeding process. A clearance between the pressure plate and the chute's outer wall—2-3 mm in this embodiment—is reserved to prevent interference between the pressure plate and the chute during the vibrating feeder's vibrations.

[0023] By adopting the above technical solution, a secondary sealing mechanism is formed between the chute and the vibrating feeder hopper through the overflow prevention skirt, the upper U-shaped groove and the lower U-shaped groove, which can perform secondary sealing on the dust overflowed from the primary sealing mechanism and improve the sealing performance.

[0024] The clamp is provided with a top screw, which enables quick disassembly and assembly of the sealing plate and the pressure plate. At the same time, the top screw on the clamp can fix the sealing plate and the pressure plate, effectively overcoming the force of the overflowed solid particulate material on the sealing plate, thereby protecting the second flexible sealing structure.

[0025] The upper and lower U-shaped grooves are both provided with top screws, which can realize the quick disassembly and assembly of the overflow prevention skirt. Compared with the traditional bolt connection, the structure of the U-shaped groove and top screw is simpler and more practical, and improves maintenance efficiency.

[0026] Although the embodiments and drawings of the present invention are disclosed for illustrative purposes, those skilled in the art will understand that various replacements, changes and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
