Description

Technical Field

[0001] The utility model relates to the technical field of inorganic fiber board production, in particular to a defibrillation and mixing device with a fiber structure. Background Art

[0002] In the field of inorganic fiber board production equipment, existing defibrillation equipment usually adopts a sealed drum body with ordinary carbon steel protrusions welded thereon, and the fiber mass is defibrillated by the rotation of the drum body. This design has the following main problems:

[0003] Firstly, during the production operation of the existing equipment, due to the airtightness inside the machine case, the ventilation is poor, heat is easily accumulated, and fire accidents are extremely likely to occur. This poses a serious threat to production safety.

[0004] Secondly, since the defibrillation knife group is made of ordinary carbon steel material, its wear resistance is poor and it wears out quickly, resulting in poor defibrillation effect, easy fiber agglomeration and blockage, thus affecting the production efficiency. Frequent replacement of the main components increases the equipment maintenance cost and downtime, and reduces the production efficiency.

[0005] In order to improve the defibrillation effect, the industry usually increases the glue powder application points to mix the fiber mass, but this single-point application method makes the glue powder and fiber mix unevenly, resulting in the need to increase the glue powder dosage to ensure the strength of the fiber board, further increasing the production cost.

[0006] In addition, the design of the existing defibrillation equipment lacks flexibility and cannot be adjusted according to different processing requirements, restricting the application range and production efficiency of the equipment.

[0007] Therefore, how to improve the ventilation of the defibrillation equipment, increase the defibrillation uniformity, enhance the equipment wear resistance, and reduce the fire risk has become the technical problem to be solved by the utility model. Summary of the Utility Model

[0008] The technical problem solved by the utility model is to provide a defibrillation and mixing device with a fiber structure to solve the problems of poor equipment ventilation, uneven defibrillation and insufficient equipment wear resistance as mentioned in the above background art in view of the defects existing in the above prior art.

[0009] To solve the above technical problems, the technical solution adopted by the utility model is as follows:

[0010] A defibrillation and mixing device with a fiber structure includes a defibrillation unit, a machine case and a mixing bin. The defibrillation unit includes a vertical trough-shaped feed inlet, a horizontal trough-shaped discharge outlet, alloy racks, an air inlet impeller, a centrifugal impeller, a sieve hole shaft tube and a spoiler;

[0011] The vertical trough-shaped feed inlet is connected to the top of the machine case and is used for gradually guiding the fiber mass to be defibrillated into the defibrillation equipment;

[0012] The horizontal trough-shaped discharge port is arranged at the bottom of the chassis and is used to discharge the defibrated fibers and mixture;

[0013] The multiple alloy racks are densely arranged on the defibrating unit and correspond to the vertical trough-shaped feed port, and are used to contact and break up the incoming fiber mass;

[0014] The air inlet impeller and the centrifugal impeller are arranged at both ends of the defibrating unit. The air inlet impeller is connected to the outside of the chassis through an air inlet pipe, and the centrifugal impeller is connected to the screen hole shaft pipe, and is used to form a centrifugal negative pressure to extract the mixture of auxiliary materials and air and send it into the mixing bin;

[0015] The screen hole shaft pipe penetrates through the middle of the defibrating unit, and a plurality of small holes are distributed along the axial direction, and are used to disperse the fibers for the first time during the air blowing process;

[0016] The spoiler is installed downstream of the screen hole shaft pipe and is used to disperse the mixture of auxiliary materials and air for the second time when it passes through.

[0017] As a further scheme of the present utility model, the small-caliber dislocation arrangement of the vertical trough-shaped feed port and the horizontal trough-shaped discharge port enables the material to form a pulling force during the feeding and defibrating processes to improve the defibrating effect.

[0018] As a further scheme of the present utility model, the vertical trough-shaped feed port is arranged at the upper part of the defibrating unit and is opposite to the alloy rack.

[0019] As a further scheme of the present utility model, the horizontal trough-shaped discharge port is arranged at the lower part of the defibrating unit and is connected to the screen hole shaft pipe for discharging the defibrated fibers and mixture.

[0020] As a further scheme of the present utility model, the mixing bin in the chassis is in a shape-fitting cooperation with the defibrating unit, and the number of defibrating units is more than 2.

[0021] Compared with the prior art, the beneficial effects of the present utility model are:

[0022] 1. The mixing bin in the chassis is in a shape-fitting cooperation with the defibrating unit, so that the mixing bin and the defibrating unit are closely fitted in shape, thereby realizing more efficient space utilization and structural stability. Due to the shape matching between the mixing bin and the defibrating unit, the voids inside the equipment can be reduced, the fluidity and uniformity of the material during the defibrating and mixing processes can be improved, and it is ensured that the fibers and auxiliary materials are fully mixed in the mixing bin.

[0023] 2. Synergistic effect of spoiler and centrifugal impeller: Through the dual effects of air blast and spoiler, the material is first dispersed after entering the equipment, and then the air volume of the centrifugal impeller and the air inlet impeller is crossed to form a second dispersion, so that the fiber and auxiliary materials can be fully mixed. The centrifugal negative pressure formed by the high-speed rotation of the centrifugal impeller further enhances the mixing uniformity of the mixture of auxiliary materials and air, thereby reducing the amount of auxiliary materials and reducing production costs while maintaining the strength of the inorganic fiberboard.

[0024] 3. The combination of the vertical slot-shaped feed port and the horizontal slot-shaped discharge port forms a higher feed pulling force through the relatively small diameter dislocation, which improves the defibration effect of the material. The vertical design of the feed port ensures that the material enters the equipment gradually, while the horizontal design of the discharge port ensures that the defibration material is finely crushed and uniform, avoiding the problem of uneven material size. This structural design improves the defibration uniformity, reduces the possibility of material blockage and equipment overload, effectively extends the service life of the equipment, and reduces maintenance costs.

Specific implementation manner

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] Please refer to Figure 1 —5. In the embodiments of the present invention, a defibering and mixing device for a fiber structure includes a defibering unit 1, a chassis 2 and a mixing bin 3. The defibering unit 1 includes a vertical trough-shaped feed inlet 4, a horizontal trough-shaped discharge outlet 5, an alloy rack 6, an air inlet impeller 7, a centrifugal impeller 10, a sieve-hole shaft tube 9 and a spoiler 8. The vertical trough-shaped feed inlet 4 is connected to the top of the chassis 2 and is used for gradually guiding the fiber mass to be defibered into the defibering device. The horizontal trough-shaped discharge outlet 5 is arranged at the bottom of the chassis 2 and is used for discharging the defibered fibers and mixtures. The air inlet impeller 7 and the centrifugal impeller 10 are sleeved on the shaft body. During operation, they are driven to rotate through the linkage of the shaft body and the motor, which all belong to the extended implementation manners known to those of ordinary skill in the art.

[0036] The alloy rack 6 is densely arranged on the defibering unit 1 and corresponds to the vertical trough-shaped feed inlet 4, and is used for contacting and dispersing the incoming fiber mass. The air inlet impeller 7 and the centrifugal impeller 10 are arranged at both ends of the defibering unit 1. The air inlet impeller 7 is connected to the outside of the chassis 2 through an air inlet pipe, and the centrifugal impeller 10 is connected to the sieve-hole shaft tube 9 and is used for forming a centrifugal negative pressure to extract the mixture of auxiliary materials and air and send it into the mixing bin 3. The sieve-hole shaft tube 9 penetrates through the middle of the defibering unit 1, and a plurality of small holes 11 are distributed along the axial direction, and are used for dispersing the fibers for the first time during the air blowing process. The spoiler 8 is installed downstream of the sieve-hole shaft tube 9 and is used for dispersing the mixture of auxiliary materials and air for the second time when it passes through.

[0037] The small-diameter arrangement of the vertical trough-shaped feed inlet 4 and the horizontal trough-shaped discharge outlet 5 enables the material to form a pulling force during the feeding and defibering processes to improve the defibering effect. The vertical trough-shaped feed inlet 4 is arranged at the upper part of the defibering unit 1 and corresponds to the alloy rack 6. The alloy rack 6 is made of wear-resistant alloy material, which prolongs the service life of the equipment and reduces the full-cycle use cost. Both the air inlet impeller 7 and the centrifugal impeller 10 are designed as flow-adjustable structures, and the air intake volume and centrifugal force are controlled by adjusting the impeller opening degree, so as to optimize the defibering and mixing effects.

[0038] The air inlet impeller 7 is connected to the sieve hole shaft tube 9, so that the fiber mass and auxiliary materials under the action of wind force are evenly distributed in the mixing bin 3. The mixing bin 3 in the machine case 2 is in a profiling fit with the defibrillation unit 1, and preferably there are 3 defibrillation units 1 to improve the structural efficiency and operation stability of the equipment; the spoiler 8 is fixedly connected to the sieve hole shaft tube 9, and a plurality of spoiler vanes are distributed along the axial direction, which are used to enhance the mixing uniformity of the mixture of auxiliary materials and air.

[0039] Example 1:

[0040] This example provides a specific application scenario and implementation method of an inorganic fiber board defibrillation device to solve the problems of poor ventilation, uneven defibrillation and insufficient abrasion resistance of the device in the background technology.

[0041] During the production process of inorganic fiber boards, it is necessary to disperse and evenly distribute the fiber mass, and at the same time add auxiliary materials to improve the quality and strength of the fiber boards. In the prior art, due to the poor ventilation of the sealed drum body, heat is easy to accumulate, resulting in a high fire risk. In addition, the defibrillation knife group made of ordinary carbon steel material wears quickly, the defibrillation effect is not good, and the fibers are easy to agglomerate and block. To solve these problems, the inorganic fiber board defibrillation device provided by the present invention has the following specific application methods:

[0042] This device includes a vertical trough-shaped feed inlet 4, a horizontal trough-shaped discharge outlet 5, an alloy rack 6, an air inlet impeller 7, a centrifugal impeller 10, a sieve hole shaft tube 9 and a spoiler 8. During the production process, the fiber mass to be defibrillated is gradually introduced into the device through the vertical trough-shaped feed inlet 4. This vertical trough-shaped design ensures the gradual feeding of materials and avoids the problem of equipment overload caused by excessive feeding of materials at one time.

[0043] The fiber mass entering the device first contacts the alloy rack 6, and under the dispersing action of the rack, the fiber mass is dispersed.

[0044] The dispersed fibers are first dispersed through the sieve hole shaft tube 9 under the action of the centrifugal impeller 10. The sieve hole shaft tube 9 penetrates through the middle of the defibrillation unit 1, and a plurality of small holes 11 are distributed along the axial direction to ensure the preliminary dispersion of the fibers during the air blowing process. The centrifugal impeller 10 forms a centrifugal negative pressure during high-speed rotation, extracts the mixture of auxiliary materials and air, and enters the sieve hole shaft tube 9.

[0045] The fiber and auxiliary material mixture entering the sieve hole shaft tube 9 is secondarily dispersed under the action of the spoiler 8. The spoiler 8 is distributed along the axial direction of the sieve hole shaft tube 9, enhancing the mixing effect of the fibers and the auxiliary materials. Through this double dispersion mechanism, the fibers and the auxiliary materials can be fully mixed, improving the mixing uniformity. Thus, while maintaining the strength of the inorganic fiber board unchanged, the amount of auxiliary materials is reduced, and the production cost is lowered.

[0046] The air inlet impeller 7 and the centrifugal impeller 10 are designed with a flow rate adjustable structure. Users can, according to different defibering requirements, control the air inlet volume and centrifugal force by adjusting the opening degree of the impeller, so as to optimize the defibering and mixing effects. This not only improves the applicability of the equipment, but also effectively cools the processing tooth positions, prevents the fire risk caused by heat accumulation, and ensures the safety of production.

[0047] The mixture of defibered fibers and auxiliary materials is discharged through the transverse trough-shaped discharge port 5. The transverse trough-shaped design ensures that the defibered materials are finely and evenly crushed, avoiding the problem of uneven material sizes. Larger material parts will continue to stay in the equipment for defibering until their sizes are small enough to pass through the discharge port, ensuring that the materials finally meet the requirements and saving users the step of secondary defibering.

[0048] Through the specific application of this embodiment, the defibering uniformity can be significantly improved, the durability of the equipment can be enhanced, the production and maintenance costs can be reduced, the problems of high fire risk, uneven defibering, and fast equipment wear existing in the prior art can be effectively solved, and the production efficiency and safety can be significantly improved.
