Description

Technical Field

[0001] This utility model belongs to the technical field of opening equipment, and in particular relates to an opening device for slag wool. Background Technology

[0002] In the field of building materials technology, utilizing metallurgical industrial waste slag to prepare slag wool, and then processing the slag wool into inorganic fiberboard, is an important technological path to achieve resource recycling. After being processed by an opening device, the slag wool fibers need to be evenly applied to the fiber surface through an adhesive application system, and then processed through laying and molding processes to produce inorganic fiberboard with specific density and strength. Agglomerated fibers are not easy to mix evenly with resin adhesive, thus affecting the material uniformity and strength of the board. It is necessary to loosen the agglomerated fibers to increase the contact area with the resin adhesive and improve the uniformity of adhesive application. When the slag ball content is high, it is easy to mix into the already loosened slag wool, affecting the subsequent board molding and board performance indicators, and needs to be removed in time.

[0003] Existing slag wool opening devices mainly consist of a conveyor belt assembly for conveying slag wool, a roller assembly for feeding the slag wool into the opening area, a beater assembly for opening, and a protective shell to prevent slag wool leakage. To reduce fiber loss and dispersion, the roller assembly and beater assembly are located inside the protective shell. Slag balls will splash and fall as the beater assembly strikes the wool. However, due to the fineness of the slag wool fibers and the splashing of slag balls, some fine fibers and slag balls will mix into the loose slag wool, thus affecting subsequent processing. Utility Model Content

[0004] The technical problem to be solved by this invention is that existing slag wool opening devices cannot clean and filter out the fiber fragments after the slag wool has been opened.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a slag wool opening device, including a conveyor belt assembly for conveying slag wool, a roller assembly for feeding slag wool into the opening area, a beater assembly for opening, and a protective shell to prevent slag wool from leaking out, wherein the roller assembly and the beater assembly are located inside the protective shell;

[0006] The bottom surface of the protective housing is provided with a dust removal trough plate located behind the beater assembly. Several friction protrusions are provided above the dust removal trough plate, and a detachable storage trough for storing slag balls and fine slag fibers is provided below the dust removal trough plate. Several cleaning shaft brushes for cleaning slag fibers are provided behind the beater assembly, and a cleaning motor for controlling the rotation of the cleaning shaft brushes is provided at the outer wall end of the protective housing.

[0007] As an improvement, the roller assembly includes a roller located behind the conveyor belt assembly and a roller motor that drives the roller to rotate, with the roller's shaft passing through both sides of the protective housing.

[0008] As an improvement, the beater assembly includes a loosening roller located behind the roller and several corner nails welded above the loosening roller.

[0009] As an improvement, the output shaft of the roller and the loosening roller are connected to the output shaft of the roller motor, and the cleaning motor and the cleaning shaft brush are all connected by a pulley structure.

[0010] As an improvement, the bottom surface of the protective housing uses a dust removal slot that is slidably connected to the detachable storage slot.

[0011] As an improvement, several air supply nozzles passing through the top surface of the protective housing are provided between the cleaning shaft brush and the loosening roller.

[0012] The advantages of this invention compared to the prior art are as follows: This device has a dust removal trough plate installed behind the beater assembly, and friction protrusions are set on the upper part of the dust removal trough plate. This ensures that after the sweeping shaft brush washes the loose slag wool, the small debris will slide into the gaps between the friction protrusions and gradually move into the gaps of the dust removal trough plate as the sweeping shaft brush washes, and finally fall into the detachable storage slot below. Each sweeping shaft brush is driven by a sweeping motor. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings.

[0019] As per the instruction manual Figure 1 , 2As shown in Figures 3 and 4, the current opening device structure includes a conveyor belt assembly 1 for conveying slag wool, a roller assembly 2 for feeding slag wool into the opening area, a beater assembly 3 for opening, and a protective shell 4 to prevent slag wool from leaking out. The roller assembly 2 and the beater assembly 3 are located inside the protective shell 4 to prevent slag balls and slag wool fibers from leaking out and to ensure the safety of the operators. The conveyor belt assembly 1 is usually made of rubber.

[0020] The roller assembly 2 includes a roller 21 located behind the conveyor belt assembly 1 and a roller motor 22 that drives the roller 21 to rotate. The shaft of the roller 21 passes through both sides of the protective housing 4. The beater assembly 3 includes an opening roller 31 located behind the roller 21 and several angle nails 32 welded above the opening roller 31. The rotation of the opening roller 31 drives the angle nails 32 to quickly strike the slag wool, causing the slag wool to be torn into small pieces. In order to ensure improved transmission efficiency, the output shaft of the roller 21 and the opening roller 31 are connected in parallel with the output shaft of the roller motor 22 using a pulley structure. The rotation speed of the roller 21 and the opening roller 31 is controlled by the diameter of the pulley.

[0021] To remove the slag wool fibers scattered by the beater assembly 3, the bottom surface of the protective housing 4 is provided with a dust removal trough plate 41 located behind the beater assembly 3. Several friction protrusions 411 are provided on the upper part of the dust removal trough plate 41. The friction protrusions 411 prevent large pieces of slag wool from clogging the dust removal trough plate 41 while ensuring the normal transmission of the slag wool. Below the dust removal trough plate 41, there is a detachable storage slot 42 for storing slag balls and fine slag fibers. To facilitate the retrieval and placement of the detachable storage slot 42, the bottom surface of the protective housing 4 uses a dust removal slot 421 that is slidably connected to the detachable storage slot 42.

[0022] The fine fibers and slag balls of the slag wool are cleaned by several cleaning shaft brushes 5 behind the beater assembly 3. The outer wall of the protective shell 4 is equipped with a cleaning motor 51 that controls the rotation of the cleaning shaft brushes 5. In order to ensure the synchronization of the cleaning shaft brushes 5, pulleys are used to connect the various cleaning shaft brushes 5 in parallel. In order to ensure the stability of transmission, the belt drive structure of the pulleys is alternately fitted on the pulleys on different end faces. The cleaning shaft brush 5 is a structure in which multiple brushes are installed on the cleaning roller.

[0023] To prevent the loosening roller 31 from rotating too fast, which would cause the loosened slag wool to fly directly over the cleaning shaft brush 5, multiple air gun nozzles 6 are made on the top surface of the protective housing 4. High-pressure airflow is then directed through the high-pressure air gun pipe to impact the cleaning shaft brush 5, ensuring that all the slag wool passes under the cleaning shaft brush 5, thus ensuring that all the slag wool is filtered and washed.

[0024] In specific implementation, the slag wool is placed on the conveyor belt assembly 1, which transports it to the inlet of the roller assembly 2. The roller motor 22 is started, and the roller 21 pulls the slag wool into the impact area of ​​the corner nail 32. After being impacted by the corner nail 32, the slag wool is broken up. The slag wool floating above the cleaning shaft brush 5 is blown onto the cleaning shaft brush 5 by the strong wind from the air gun nozzle 6. As the cleaning shaft brush 5 rotates, it enters the area below the cleaning shaft brush 5, causing the slag wool to move and be brushed on the dust removal trough plate 41. The slag balls and broken fibers will fall into the gaps of the friction protrusions 411 and fall into the detachable storage trough 42 through the through hole below the dust removal trough plate 41. After being brushed, the slag wool will fall from the outlet behind the cleaning shaft brush 5 under the push of the cleaning shaft brush 5. In order to avoid the slag wool scattering too widely, the outlet is usually opened downwards to facilitate the receiving of the cloth bag.

[0025] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
