Description

Technical Field

[0001] This utility model relates to a screw conveyor for a waste salt melting furnace, specifically a screw conveyor for preventing blockage during feeding into a waste salt melting furnace. Background Technology

[0002] Waste salt melting furnaces utilize screw conveyors to transport waste salt. However, the waste salt sometimes clumps together, and large pieces falling directly into the screw conveyor can cause blockages, necessitating shutdown for maintenance. Currently, most solutions to this problem involve installing de-flaking devices on the screw blades of the conveyor, but this method is not very effective and still easily leads to blockages inside the conveyor. Utility Model Content

[0003] To address the shortcomings of the prior art, this invention provides a screw conveyor for preventing blockage in the feed of a waste salt melting furnace. The screw conveyor is installed at the outlet of the waste salt melting furnace to facilitate the transport of waste salt. A crushing roller assembly and a dispersing plate are installed at the feed inlet of the conveyor to crush and disperse large pieces of waste salt, preventing blockage.

[0004] To achieve the above technical objectives, the present invention adopts the following technical solution: a screw conveyor for preventing blockage of waste salt melting furnace feed, comprising a screw conveyor housing located at the outlet of the waste salt melting furnace, a feed inlet located at the upper part of the screw conveyor housing, a crushing roller assembly and a dispersing plate located inside the feed inlet, the crushing roller assembly located above the dispersing plate, the dispersing plate being inverted V-shaped, and the dispersing plate having multiple dispersing holes.

[0005] The crushing roller assembly includes two rollers, the shafts of which are mounted on the wall of the feed inlet. The outer wall of each roller is provided with a rack, and the racks of the two rollers are staggered. The two rollers rotate relative to each other.

[0006] The dispersion plate is provided with connectors at both ends of the V-shaped junction, and the connectors are used to connect the feed inlet.

[0007] The connector includes an elongated hole, a long bolt, a handle, a spring, and a notch. The elongated hole is arranged along the V-shaped boundary line, and one end penetrates the dispersion plate to form a blind hole. The long bolt passes through the elongated hole and can move within it. The inner end of the elongated hole has the notch that communicates with the outside. The handle is located in the notch and is fixedly connected to the long bolt. When the handle is moved, the long bolt can move, so that its outer end extends out or retracts completely into the elongated hole. The spring is located within the notch.

[0008] The outer edge of the notch is provided with a corrugated sheet.

[0009] In summary, this utility model achieves the following technical effects:

[0010] This invention features a screw conveyor at the outlet of a waste salt melting furnace to facilitate the transport of waste salt. A crushing roller assembly and a dispersing plate at the inlet of the conveyor can crush and disperse large pieces of waste salt, preventing blockage. Attached Figure Description

[0018] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0019] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0021] Example:

[0022] Figure 1 It is a screw conveyor for preventing blockage of waste salt melting furnace feed, including a screw conveyor housing 1 located at the outlet of the waste salt melting furnace, a feed inlet 2 located on the upper part of the screw conveyor housing 1, a crushing roller group 3 and a dispersing plate 4 arranged inside the feed inlet 2, the crushing roller group 3 located above the dispersing plate 4, the dispersing plate 4 being inverted V-shaped, and the dispersing plate 4 having multiple dispersing holes 41.

[0023] This invention features a screw conveyor at the outlet of a waste salt melting furnace to facilitate the transport of waste salt. The crushing roller group 3 and the dispersing plate 4 are designed to crush and disperse large pieces of waste salt, preventing blockage at the feed inlet.

[0024] The crushing roller assembly 3 includes two rollers, the shafts of which are mounted on the wall of the feed inlet 2. The outer wall of the rollers is provided with racks 31, and the racks 31 of the two rollers are staggered, allowing the two rollers to rotate relative to each other.

[0025] Two rollers can break large pieces of waste salt into smaller pieces, reducing the chance of clogging and improving transportation efficiency.

[0026] Figure 2 This is a schematic diagram of a dispersion plate. The dispersion plate 4 has connectors at both ends of the V-shaped junction, and the connectors are used to connect to the feed inlet 2.

[0027] This invention sets the dispersion holes of the dispersion plate to any shape, such as round holes, grid holes, or elongated holes. Round holes and elongated holes can be obtained by direct drilling, and grid holes can be formed by combining multiple horizontal and vertical grids to form a dispersion plate. Figure 2 It is in the form of a round hole. Figure 4 It uses a grid-like perforated design. In this embodiment, a grid-like perforated design is adopted. The thickness of the grid is much smaller than the size of the perforation, which can both disperse waste salt and prevent clogging. Small pieces of waste salt falling on the grid will be further broken up. The small thickness of the grid means that the outermost grid occupies a small area in contact with the feed inlet, preventing waste salt from piling up on the outermost grid.

[0028] Figure 2 and Figure 3 A schematic diagram of the connector is shown. Figure 3 yes Figure 2 A partially enlarged schematic diagram shows that the connector includes an elongated hole 45, a long bolt 46, a handle 42, a spring 47, and a notch 43. The elongated hole 45 is set along the V-shaped boundary line, and one end penetrates the dispersion plate 4 to form a blind hole. The long bolt 46 passes through the elongated hole 45 and can move within it. The inner end of the elongated hole 45 has the notch 43, which communicates with the outside. The handle 42 is located in the notch 43 and is fixedly connected to the long bolt 46. When the handle 42 is moved, the long bolt 46 can move, so that its outer end extends out or retracts completely into the elongated hole 45. The spring 47 is located within the notch 43.

[0029] A corrugated sheet is provided on the outer edge of the notch 43.

[0030] During installation, squeeze the two handles and push them inward so that the long bolt 46 is fully retracted into the long hole 45. Place the dispersing plate 4 from the top of the feed inlet to the designated position, release the two handles, and under the action of the spring, the long bolt 46 extends outward and enters the fixing hole (not shown) on the inner wall of the feed inlet. Then install the two rollers and it is ready for use.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
