Description

Technical Field

[0001] This invention relates to the field of melt blending technology for energy-saving and sound-insulating building materials, and particularly to a melt blending device and method for energy-saving and sound-insulating building materials. Background Technology

[0002] Melting refers to the process in which the kinetic energy of molecular thermal motion increases with rising temperature, leading to the destruction of crystals and the transformation of a substance from a crystalline phase to a liquid phase; it is a first-order phase transition, with an increase in enthalpy, entropy, and volume; the temperature at which melting occurs is called the melting point or melting temperature; some energy-saving and sound-insulating building materials require the uniform mixing of various raw materials through a melt blending device during the production process to prepare the corresponding energy-saving and sound-insulating building materials.

[0003] In existing energy-saving and sound-insulating building material melt blending devices, multiple raw materials are simultaneously introduced into the processing tank during use. However, the same raw material contains particles of different sizes. Raw materials with larger particles require a longer melting time and a longer time to achieve uniform blending. Compared to large-particle raw materials, small-particle raw materials require much less time. Processing raw materials of different particle sizes in the same processing tank will increase the melt blending time, reduce the finishing efficiency of melt blending, and thus reduce the use value of the melt blending device. Summary of the Invention

[0004] This invention discloses a melt-blending device for energy-saving and sound-insulating building materials, aiming to solve the technical problem that existing melt-blending devices for energy-saving and sound-insulating building materials introduce multiple raw materials into the processing tank at the same time. However, the same raw material contains particles of different sizes. The raw material with larger particles requires a longer melting time and a longer time to achieve uniform blending. Compared with large-particle raw materials, small-particle raw materials require much less time. Placing raw materials of different particle sizes in the same processing tank will increase the melt-blending time and reduce the finishing efficiency of melt-blending.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A melting and blending device for energy-saving and sound-insulating building materials includes a blending box and a separating melting and blending assembly. A heating layer is fixedly connected inside the blending box, and electric heating tubes are fixedly connected at equal intervals inside the heating layer. An upper guide ring and a lower guide ring are fixedly connected to the top and bottom of the heating layer, respectively. The separating melting and blending assembly includes a sieve plate, which is attached to the side wall of the heating layer. A scraper is fixedly connected to the bottom of the sieve plate. An mounting hole is annularly opened on the outer side of the upper guide ring, and a heat-conducting rod is fixedly connected inside each mounting hole. One end of the heat-conducting rod contacts the outer side of the heating layer, and the other end is located near the center point of the sieve plate. Two motor frames are fixedly connected to the outer side of the blending box at the sieve box location, and a forward and reverse motor is fixedly connected to the side of each motor frame facing the sieve plate. The output shafts of the forward and reverse motors are fixedly connected to a rotating shaft via a coupling. A shaft plate is fixedly connected to the outer side of the blending box at the end of the rotating shaft away from the forward and reverse motors, and the rotating shaft is connected to the outer side of the shaft plate via a bearing.

[0007] By incorporating a partitioned melt-blending assembly, during the raw material melt-blending operation, drive motor two is activated, which rotates the screening plate. The rotating screening plate rapidly screens and mixes the raw materials, with larger particles located on the screening plate. During the melt-blending process, each heat-conducting rod directly transfers heat from the heating layer to the material near the center of the screening plate. Compared to the melting and blending of the raw materials below, the heat transfer at the top is faster. Simultaneously, the forward and reverse motors are activated, driving the stirring blades and annular cutting blades to cut and stir the large particles of raw materials in the initial melt state. This ensures that the degree of melt-blending of the large particles above is similar to that of the small particles below, eliminating the need to extend the melt-blending time based on particle size, accelerating the melt-blending process, and enhancing the usability of the melt-blending device.

[0008] In a preferred embodiment, three stirring blades are fixedly connected to the outer side of the rotating shaft, and each of the three stirring blades has cutting teeth on the outer side near the bottom end. Two mounting rods are fixedly connected to the outer side of both ends of the rotating shaft, and the same annular cutting blade is fixedly connected to the outer side of the two mounting rods on one side.

[0009] In a preferred embodiment, a second drive motor is fixedly connected to the top of the mixing box, and a stirring shaft is fixedly connected to the output shaft of the second drive motor via a coupling. A through hole is opened at the center point of the sieve plate, through which the stirring shaft passes. An outer connecting ring is fixedly connected to the stirring shaft near the inner wall of the top of the mixing box.

[0010] In a preferred embodiment, two cylinders are fixedly connected to the top of the outer ring, and the output ends of the two cylinders are fixedly connected to the same lifting ring. Two connecting rods are fixedly connected to the top of the lifting ring, and the two connecting rods are fixedly connected to the bottom inner wall of the screening plate. Lifting rods are distributed in a ring at the bottom of the lifting ring, and stirring rods are fixedly connected at equal intervals to the outer side of the lifting rods.

[0011] In a preferred embodiment, an auxiliary feeding assembly is provided on the outer side of the lifting ring, and the auxiliary feeding assembly includes a feeding auxiliary ring cover. Two fixing rods are fixedly connected to the inner side of the feeding auxiliary ring cover, and both fixing rods are fixedly connected to the top of the lifting ring.

[0012] With the auxiliary feeding component in place, after the building materials are melted and blended, when they are collected, the adjusting cylinder drives the screening plate and the feeding auxiliary ring to move downwards. During the downward movement, the scraper below the screening plate scrapes off the raw materials adhering to the side wall of the heating layer. The second air compressor is started, and the air filtered by the air filter cartridge is introduced into the feeding auxiliary ring and blown out through the blowhole, thereby blowing the molten material below and further accelerating its fall. As the cylinder drives the screening plate to descend, each stirring rod also descends accordingly. The second drive motor is in a continuous working state. During the feeding of the molten material, the stirring rods continuously stir and mix it, improving the uniformity of the melt blending of the building materials while completing the feeding.

[0013] In a preferred embodiment, a mounting bracket is fixedly connected to the outer side of the mixing chamber, and a drive motor is fixedly connected to one side of the mounting bracket. An air filter cartridge is fixedly connected to the output shaft of the drive motor via a coupling. A retaining ring is fixedly connected to the side of the mounting bracket facing the air filter cartridge. The air filter cartridge is inserted into the inner side of the retaining ring. An air compressor is fixedly connected to the top of the mixing chamber. An air inlet pipe is fixedly connected to the air inlet end of the air compressor. One end of the air inlet pipe is connected to the inside of the air filter cartridge via a bearing. An air delivery pipe is fixedly connected to the air delivery end of the air compressor. The air delivery pipe is inserted into the inside of the material feeding auxiliary ring cover. A blowhole is annularly opened on the outer side of the material feeding auxiliary ring cover.

[0014] In a preferred embodiment, a discharge hole is provided at the center of the bottom of the mixing chamber, and a discharge pipe is fixedly connected inside the discharge hole. The discharge pipe is located on the outer side below the mixing chamber and is connected to a discharge valve via a flange. An annular guide plate is fixedly connected to the top of the discharge pipe. The annular guide plate is in contact with the inner wall of the mixing chamber and is located below the heating layer. Grounding brackets are distributed in a ring at the bottom of the mixing chamber.

[0015] In a preferred embodiment, the top of the blending box has a feed hole, and a feed processing assembly is provided at the feed hole. The feed processing assembly includes a feed frame, which is fixedly connected to the inside of the feed hole. Hollow air hoods are fixedly connected to the inner walls of the feed frame near the bottom. Air holes are opened on the outer sides of the two hollow air hoods facing upward. A spin shaft is connected to the inner wall of the feed frame between the two hollow air hoods via a bearing. Dispersing wires are fixedly connected at equal intervals to the outer side of the spin shaft. An air compressor is fixedly connected to the top of the blending box. An air pipe is fixedly connected to the air supply end of the air compressor. A connecting hole is opened on the outer side of the two hollow air hoods. The same connecting pipe is fixedly connected to the inside of the two connecting holes. The air pipe is inserted into the inside of the connecting pipe.

[0016] In a preferred embodiment, connecting rods are fixedly connected to both sides of the feeding frame, and the same hollow dust collection hood is fixedly connected to the outer side of the two connecting rods. The hollow dust collection hood has a dust collection hole on its downward-facing outer side. A support plate is fixedly connected to one side of the feeding frame, and a dust collection box is fixedly connected to the top of the support plate. A dust collection pump is fixedly connected to one side of the dust collection box. An extraction pipe is fixedly connected to the dust collection end of the dust collection pump, and the extraction pipe is inserted into the interior of the hollow dust collection hood. The dust conveying end of the dust collection pump is connected to the interior of the dust collection box through a pipe.

[0017] With the feeding processing component in place, after each raw material is introduced into the feeding frame, the first air compressor is started. The first air compressor blows the raw materials through the air holes on the two hollow air hoods. At the same time, the compressed gas drives the spin shaft to rotate. The dispersing filaments on the outside of the spin shaft stir and disperse the raw materials. The agitation of the compressed gas and the dispersing filaments work together to achieve preliminary mixing between the raw materials. The dispersion of the raw materials causes the dust they carry to be pushed out by the compressed gas. The dust pump is started and collects the dust through the dust suction holes on the hollow dust suction hood to avoid the quality of the melt-blended material being affected by excessive dust content in the raw materials.

[0018] A method of using an energy-saving and sound-insulating building material melt blending device, comprising the following steps:

[0019] Step 1: After each raw material is introduced into the feed box, start the air compressor. The air compressor blows the raw materials through the air holes on the two hollow air vents. At the same time, the compressed gas drives the spin shaft to rotate. The dispersing filaments on the outside of the spin shaft stir and disperse the raw materials. The blowing of the compressed gas and the dispersing filaments work together to achieve the initial mixing of the raw materials.

[0020] Step 2: During the raw material melting and blending operation, start drive motor 2. Drive motor 2 drives the screen plate to rotate. The rotating screen plate quickly screens and mixes the raw materials. Large particles of raw materials are located on the screen plate. At the same time, start the forward and reverse motors. The forward and reverse motors drive the stirring blades and the annular cutting blades to cut and stir the large particles of raw materials in the initial molten state. This makes the degree of melting and blending of the large particles of raw materials above similar to the degree of melting and blending of the small particles of raw materials below. After the melting and blending is completed, start feeding the raw materials.

[0021] Step 3: Adjust the cylinder to move the screening plate and the feeding auxiliary ring cover downwards. During the downward movement, the scraper below the screening plate will scrape off the raw material adhering to the side wall of the heating layer. Start the second air compressor. The second air compressor will introduce the air filtered by the air filter into the feeding auxiliary ring cover and blow it out through the blowhole, thereby blowing the molten material below and further accelerating its fall. After being guided by the annular guide plate, the molten and blended material is discharged through the feeding pipe. The staff collects it and the operation ends.

[0022] As can be seen from the above, the energy-saving and sound-insulating building material melting and blending device provided by the present invention has the following technical effects: when performing raw material melting and blending operation, the second drive motor is started, which drives the screen plate to rotate. The rotating screen plate quickly screens and mixes the raw materials. Large particles of raw materials are located on the screen plate. During the melting and blending process, each heat-conducting rod directly transfers the heat from the heating layer to the material near the center point of the screen plate. Compared with the melting and blending of raw materials below, the heat transfer at the top is faster. At the same time, the forward and reverse motors are started, which drive the stirring blades and the annular cutting blades to cut and stir the large particles of raw materials in the initial melting state. This makes the melting and blending degree of the large particles of raw materials above similar to that of the small particles of raw materials below, eliminating the need to extend the melting and blending time according to the different particles and accelerating the melting and blending progress of raw materials.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] The energy-saving and sound-insulating building material melt blending device disclosed in this invention is mainly applied to the existing energy-saving and sound-insulating building material melt blending device. In the process of using the device, multiple raw materials are introduced into the processing tank at the same time. However, the same raw material contains particles of different sizes. The raw material with larger particles requires a longer melting time and a longer time to be blended evenly. Compared with the raw material with large particles, the raw material with small particles takes much less time. The process of placing raw materials with different particle sizes in the same processing tank will increase the melting and blending time and reduce the processing efficiency of the melt blending.

[0037] In specific application scenarios, when performing raw material melting and blending, drive motor 212 is started, which drives the screening plate 501 to rotate. The rotating screening plate 501 quickly screens and mixes the raw materials. Large particles of raw materials are located on the screening plate 501. During the melting and blending process, each heat-conducting rod 506 directly transfers the heat from the heating layer 4 to the material near the center point of the screening plate 501. Compared with the melting and blending of raw materials below, the heat transfer at the top is faster. At the same time, the forward and reverse motor 503 is started, which drives the stirring plate 509 and the annular cutting plate 508 to cut and stir the large particles of raw materials in the initial melting state. This makes the degree of melting and blending of the large particles of raw materials above similar to that of the small particles of raw materials below. There is no need to extend the melting and blending time according to the different particles, which accelerates the melting and blending progress of raw materials and improves the use value of the melting and blending device.

This makes the degree of melting and blending of the large particles of raw materials above similar to the degree of melting and blending of the small particles of raw materials below. After the melting and blending is completed, the material is fed into the machine.

[0048] Step 3: Adjust cylinder 19 to move screen plate 501 and feeding auxiliary ring cover 708 downward. During the downward movement, scraper 502 below screen plate 501 scrapes off the raw material attached to the side wall of heating layer 4. Start air compressor 2 704. Air compressor 2 704 introduces the air filtered by air filter cartridge 701 into feeding auxiliary ring cover 708 and blows it out through blowhole 709, thereby blowing the molten material below and further accelerating its fall.

After the melting and blending is completed, start feeding it. Step 3: Adjust the cylinder (19) to drive the screening plate (501) and the feeding auxiliary ring cover (708) to move down. During the downward movement, the scraper (502) below the screening plate (501) scrapes off the raw material attached to the side wall of the heating layer (4). Start the second air compressor (704). The second air compressor (704) introduces the air filtered by the air filter cartridge (701) into the feeding auxiliary ring cover (708) and blows it out through the blowhole (709) to blow the molten material below, further accelerating its fall. After the molten and blended material is guided by the annular guide plate (3), it is discharged through the feeding pipe (10). The staff collects it and the operation ends.
