Description

Technical Field

[0001] The utility model relates to the technical field of rock wool production, in particular to a centrifuge glue spraying structure for producing rock wool boards. Background Art

[0002] In the building materials industry, rock wool, as a high-quality thermal insulation material, is highly sought after for its excellent fire resistance, sound insulation, and environmental friendliness. Rock wool board, as an important form of rock wool product, is widely used in a variety of applications, including exterior wall insulation, roof insulation, and pipe insulation. Glue spraying is a crucial step in the production of rock wool board, directly impacting the board's bond strength, overall performance, and service life. Glue spraying involves evenly applying a specific glue to the rock wool fibers to promote interfiber bonding, resulting in a structurally stable, high-performance rock wool board.

[0003] Currently, centrifuge glue spraying technology is widely used in the production of rock wool boards. The basic working principle of this technology is as follows: first, carefully selected rock raw materials are melted at high temperatures. The molten rock is then ejected through a high-speed centrifuge, forming fine rock wool fibers. These fibers are ejected under the influence of centrifugal force. Simultaneously, a glue spraying device is installed in the fiber ejection path, spraying a pre-mixed glue in the form of a mist evenly onto the flying rock wool fibers. As the fibers and glue are thoroughly mixed, they fall onto the forming plate below. After subsequent processes such as compaction and curing, the rock wool board is finally formed.

[0004] While existing centrifuge glue spraying technology has played an important role in rock wool board production, it still has some significant drawbacks. Since the glue spraying devices are typically located around the centrifuge, the glue is sprayed from the periphery toward the center. This method of glue spraying can easily lead to uneven mixing of the rock wool fibers and the glue, especially at the edges of the fiber bundle, where insufficient or excessive glue coverage often occurs. Furthermore, due to the high-speed rotation of the centrifuge and the directionality of the fiber spraying, the glue can be disturbed by airflow during the spraying process, further affecting the glue spraying effect, resulting in inconsistent localized bond strength in the rock wool board and affecting the overall quality. Utility Model Content

[0005] In order to overcome the disadvantage of uneven glue spraying, the utility model provides a centrifuge uniform glue spraying structure for producing rock wool boards.

[0006] A centrifuge glue spraying structure for producing rock wool boards includes a centrifuge and a fiber nozzle. The centrifuge is used to throw out molten rock to form fine rock wool fibers. The centrifuge is provided with multiple fiber nozzles for spraying rock wool fibers. The centrifuge also includes a glue spraying component and a protective component. The centrifuge is provided with a glue spraying component for dispersing and spraying glue and uniformly mixing it with the rock wool fibers. The glue spraying component is provided with a protective component for protecting the glue spraying component.

[0007] As a further preferred solution, the glue spraying assembly includes a glue spraying shell, a glue line tube, a diverter tube and a conical plug. Multiple glue spraying shells are installed on the centrifuge. The glue spraying shells rotate at high speed with the rotating parts of the centrifuge. A glue line tube is provided in the glue spraying shell. The outer end of the glue line tube is connected to the diverter tube. A conical plug is installed in the diverter tube port. In order to optimize the structure and reduce weight, the glue spraying shell is designed with a structural cavity inside while ensuring sufficient structural strength.

[0008] As a further preferred solution, the protective component includes a dust shell A, a dust shell B, a rotating lower seat, a rotating upper seat, an anti-slip rope and a pin. The dust shell A and the dust shell B are respectively connected to the rotating lower seat and the rotating upper seat at one end, and the rotating lower seat and the rotating upper seat are hinged to each other. The cavity formed by the dust shell A and the dust shell B is used to wrap the diversion pipe, and the cylindrical sleeve formed by the other end of the dust shell A and the dust shell B is arranged on the rubber circuit pipe. The lower end of the dust shell is connected to the anti-slip rope, and the other end of the anti-slip rope is connected to the pin. When the dust shell A and the dust shell B are merged, the pin is slidably connected to both sides of the cylinder of the dust shell A and the dust shell B.

[0009] As a further preferred solution, a camera is also included. A camera is installed on the top of the centrifuge. The camera is installed on the top of the centrifuge, and its viewing angle is aimed at the main spraying area of ​​the rock wool fiber, so as to monitor the mixing of the fiber and glue in real time.

[0010] As a further preferred solution, it further comprises a lifting ring, and a plurality of lifting rings are installed on both sides of the centrifuge.

[0011] As a further preferred solution, it further comprises a storage hanger, and the centrifuge is connected to the storage hanger.

[0012] As a further preferred solution, it further includes a counterweight block, and a plurality of counterweight blocks are arranged at the bottom of both sides of the centrifuge.

[0013] Compared with the prior art, the utility model has the following advantages:

[0014] 1. Through the glue spraying assembly, the glue enters the diversion pipe and is impacted by the conical plug, realizing multi-stage dispersion and atomization of the glue, so that the glue can be sprayed evenly and finely on the rock wool fiber, achieving the effect of fully and evenly mixing the glue and the rock wool fiber. The setting of multiple glue pipes further enhances the uniformity of the glue spraying, and finally achieves the purpose of uniform glue spraying.

[0015] 2. The dustproof shell A and dustproof shell B provide a protective barrier for the shunt pipe and its internal structure, preventing external factors such as dust and impurities from entering the shunt pipe, avoiding the risk of clogging or contamination of the shunt pipe, effectively extending the service life of the spraying component, ensuring the normal operation of the spraying system, and indirectly promoting the uniformity of the spraying.

DETAILED DESCRIPTION

[0023] The following further illustrates the technical solution with reference to specific embodiments. It should be noted that terms such as "up," "down," "left," and "right" used herein to indicate directions refer only to the positions of the structures depicted in the corresponding drawings. Component numbers, such as "first" and "second," are used solely to distinguish the components being described and do not convey any sequential or technical meaning. References to "connected" and "coupled" in this application, unless otherwise specified, include both direct and indirect connections (couplings).

[0024] Example: A centrifuge glue spraying structure for producing rock wool board, such as Figure 1-Figure 5 As shown, it includes a centrifuge 1 and a fiber nozzle 2. The centrifuge 1 is used to throw out the molten rock to form fine rock wool fibers. The centrifuge 1 is provided with multiple fiber nozzles 2 for spraying rock wool fibers. It also includes a glue spraying component and a protection component. The centrifuge 1 is provided with a glue spraying component for dispersing and spraying glue and uniformly mixing it with the rock wool fibers. The glue spraying component is provided with a protection component for protecting the glue spraying component.

[0025] like Figure 2-Figure 4As shown, the glue spraying assembly includes a glue spraying shell 3, a glue line tube 5, a diverter tube 6 and a tapered plug 7. Four glue spraying shells 3 are installed on the centrifuge 1. The glue spraying shells 3 rotate at high speed with the rotating parts of the centrifuge 1. A glue line tube 5 is provided in the glue spraying shell 3. The outer end of the glue line tube 5 is connected to the three-channel diverter tube 6. A tapered plug 7 is installed in the end of each diverter tube 6. The end of the tapered plug 7 facing the glue line tube 5 is tapered. When the glue passes through the tapered plug 7, it will diffuse to the surroundings. In order to optimize the structure and reduce the weight, the glue spraying shell 3 is designed with a structural cavity 4 inside while ensuring sufficient structural strength.

[0026] like Figure 1 and Figure 5 As shown, the protection component includes a dustproof shell A8, a dustproof shell B9, a rotating lower seat 10, a rotating upper seat 11, an anti-slip rope 12 and a pin 13. One end of the dustproof shell A8 and the dustproof shell B9 are respectively connected to the rotating lower seat 10 and the rotating upper seat 11, and the rotating lower seat 10 and the rotating upper seat 11 are hinged to each other. The cavity formed by the dustproof shell A8 and the dustproof shell B9 is used to wrap the diversion pipe 6. The cylindrical sleeve formed by the other end of the dustproof shell A8 and the dustproof shell B9 is arranged on the rubber pipe 5. The lower end of the dustproof shell is connected to the anti-slip rope 12, and the other end of the anti-slip rope 12 is connected to the pin 13. When the dustproof shell A8 and the dustproof shell B9 are merged, the pin 13 is slidably connected to both sides of the cylinder of the dustproof shell A8 and the dustproof shell B9.

[0027] When the fiber nozzle 2 sprays the rock wool fiber, the glue spraying shell 3 drives the glue line pipe 5 to rotate at high speed, and the glue discharging device fills the glue line pipe 5 with glue. After passing through the glue line pipe 5, the glue is dispersed for the first time and directly hits the tapered plug 7 along the diversion pipe 6. The glue is dispersed for the second time, and the glue spraying shell 3 rotates at a rotating speed to achieve the purpose of atomizing the glue, and sprays the glue from the center to the surrounding areas. The glue can be evenly distributed on the rock wool fiber, thereby achieving better bonding effect and higher product quality. Multiple glue spraying shells 3 and glue line pipes 5 are provided, and a multi-nozzle design is adopted to further improve the uniformity and efficiency of glue spraying, so as to achieve the purpose of uniform glue spraying;

[0028] The diameter of the shunt pipe 6 is small, so when it is not working, take out the dustproof shell A8 and the dustproof shell B9, and put the dustproof shell A8 and the dustproof shell B9 on the shunt pipe 6. The dustproof shell A8 and the dustproof shell B9 can rotate with each other by rotating the lower seat 10 and the upper seat 11. After being put on the rubber tube 5, the pin 13 is inserted into the dustproof shell A8 and the dustproof shell B9 to fix the dustproof shell A8 and the dustproof shell B9, protecting the shunt pipe 6, preventing external factors such as dust and impurities from entering the inside of the shunt pipe 6, and avoiding the risk of blockage or contamination of the shunt pipe 6. When work is needed, remove the pin 13, and the anti-slip rope 12 connected to the pin 13 can prevent it from being lost, which is convenient for subsequent direct use.

[0029] like Figure 1and Figure 6 As shown, a camera 14 is also included. The camera 14 is installed on the top of the centrifuge 1. The camera 14 is installed on the top of the centrifuge 1, and its viewing angle is aimed at the main spraying area of ​​the rock wool fiber to monitor the mixing of the fiber and the glue in real time.

[0030] Camera 14 is used to capture the fusion of glue and rock wool fibers. Modern rock wool board production lines also introduce intelligent monitoring systems to monitor the status of rock wool fibers in real time and provide timely and accurate information feedback to production managers.

[0031] like Figure 1 and Figure 6 As shown, the centrifuge 1 further includes a lifting ring 15 , and a plurality of lifting rings 15 are installed on both sides of the centrifuge 1 .

[0032] In order to facilitate the movement and transportation of the centrifuge 1 , lifting rings 15 are designed on both sides of the centrifuge 1 . These lifting rings 15 help to keep the centrifuge 1 horizontal during transportation, thereby ensuring the stability of the device.

[0033] like Figure 6 As shown, the centrifuge 1 further includes a storage hanger 16 , and the storage hanger 16 is connected to the centrifuge 1 .

[0034] The storage hanger 16 can be used to place the dustproof shell A8 and the dustproof shell B9, which are used in conjunction with the centrifuge 1 and are convenient to take out when in use.

[0035] like Figure 1 and Figure 6 As shown, the centrifuge 1 further includes a counterweight 17 , and a plurality of counterweights 17 are provided at the bottom of both sides of the centrifuge 1 .

[0036] When centrifuge 1 rotates at high speeds, various factors may generate unbalanced forces, causing it to wobble. Adding counterweights 17 on both sides of centrifuge 1 can offset these unbalanced forces, allowing centrifuge 1 to achieve dynamic balance. Furthermore, depending on the wobble of centrifuge 1, multiple counterweights 17 can be used on both sides to coordinate with each other to achieve balance. The number of counterweights can vary, ultimately reducing the vibration amplitude of centrifuge 1 during operation and improving the stability of the device.

[0037] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
