Description

Technical Field

[0001] This utility model relates to the field of fireproof aerogel insulation cotton production technology, specifically to a mixing machine for producing fireproof aerogel insulation cotton. Background Technology

[0002] With increasingly stringent global requirements for building energy efficiency, the demand for building insulation materials is growing significantly. Traditional insulation materials have limitations in both fire resistance and overall insulation performance. Fire-resistant aerogel insulation cotton has emerged to address this need, providing excellent insulation while effectively preventing the spread of flames, thus meeting the construction industry's demand for high-performance fire-resistant insulation materials. The mixing machine, as a key piece of equipment in the production of fire-resistant aerogel insulation cotton, is being developed in response to the building insulation industry's need for high-quality material production.

[0003] Traditional fire-retardant aerogel insulation cotton mixing machines are not meticulous enough in screening impurities in raw materials. They do not use different filters to vibrate and screen impurities in different raw materials, resulting in a large number of impurities remaining in the produced fire-retardant aerogel insulation cotton. This greatly affects the uniformity of the fire-retardant aerogel insulation cotton and reduces the thermal insulation performance of the product. During the mixing process, no equipment is used to dry the fire-retardant aerogel insulation cotton, resulting in a high moisture content in the raw materials. The accumulation of a large amount of fire-retardant aerogel insulation cotton can easily lead to internal chemical changes or microbial growth, reducing the effective service life of the product. Utility Model Content

[0004] The purpose of this utility model is to provide a mixing machine for producing fire-retardant aerogel insulation cotton, solving the following technical problems: Traditional fire-retardant aerogel insulation cotton mixing machines do not screen impurities in raw materials carefully enough, and do not use different filters to vibrate and screen impurities in different raw materials, resulting in a large number of impurities remaining in the produced fire-retardant aerogel insulation cotton. This has a significant impact on the uniformity of the fire-retardant aerogel insulation cotton and reduces the thermal insulation performance of the product. During the mixing process, no equipment is used to dry the fire-retardant aerogel insulation cotton, resulting in a high moisture content in the raw materials. The accumulation of a large amount of fire-retardant aerogel insulation cotton can easily lead to internal chemical changes or microbial growth, reducing the effective service life of the product.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A mixing machine for producing fire-retardant aerogel insulation cotton includes a housing. A filtering mechanism is installed at the upper end of the housing. The filtering mechanism removes impurities and metal fragments from the fire-retardant aerogel insulation cotton using a vibrating screen. The filtering mechanism includes a first filter screen movably fitted inside the housing. The first filter screen filters the aerogel powder raw material. A vibrating motor is fixed to the bottom of the first filter screen. A support rod is fixed to the middle of the lower end of the first filter screen. A reciprocating device is fixed to the end of the support rod, which drives the first filter screen to move horizontally back and forth. A second filter screen is installed at the lower end of the first filter screen. The second filter screen filters the fire-retardant aerogel insulation cotton fiber raw material. The second filter screen has the same structure as the first filter screen. A first feed inlet is opened on one side of the housing, a second feed inlet is opened at the upper end of the housing, and a discharge outlet is opened at the lower end of the housing.

[0007] As a further embodiment of this utility model: the translational reciprocating device includes a first servo motor, a lead screw, and a first slider. The first servo motor drives the first slider to move horizontally and reciprocally on the lead screw, and the upper end of the first slider is fixedly connected to the support rod.

[0008] As a further embodiment of this utility model: a through hole is provided at the upper end of the outer side of the box, and a slide rail is provided at both the upper and lower ends of the through hole. A baffle is slidably installed on the slide rail. The baffle moves horizontally on the slide rail to facilitate the vibration motor sliding out of the box. A moving rod is fixed in the middle of the baffle.

[0009] As a further embodiment of this utility model: a second servo motor is symmetrically fixedly installed on the outer side of the box, a stirring shaft is fixed on the output shaft of the second servo motor, a first stirring blade and a fixing rod are fixed on the upper surface of the stirring shaft, and a second stirring blade is fixed on the fixing rod.

[0010] As a further embodiment of this utility model: heating plates are symmetrically fixedly installed on the inner side of the box, and a protective shell is fixed on the outer side of the heating plates. The protective shell has multiple ventilation holes for ventilation and heat dissipation of the heating plates.

[0011] As a further embodiment of this utility model: an inclined plate is fixed to the bottom of the box body, and bearing boxes are symmetrically fixed to both ends of the bottom of the box body. A push-pull rod is movably installed inside the bearing box, and a second slider is fixedly connected to the end of the push-pull rod. A feed plate is fixed to the upper part of the second slider.

[0012] As a further embodiment of this utility model: a brush is fixedly provided on the outer side of the box at the upper end of both the first and second filter screens, and the brush is used to remove impurities remaining on the filter screens after the vibrating screen.

[0013] As a further embodiment of this utility model: a base is fixed to the bottom of the box, and ventilation holes are provided on the side of the box.

[0014] The beneficial effects of this utility model are:

[0015] (1) The fireproof aerogel insulation cotton mixing machine of this utility model drives the first slider to move back and forth on the screw via the first servo motor, thereby driving two different filter screens to move back and forth. The filter screens are vibrated by the vibrating motor, so that different filter screens are used to filter different raw materials of fireproof aerogel insulation cotton when they are fed, avoiding the accumulation of raw materials around impurities, which would lead to inconsistent insulation performance in different parts and reduce product quality.

[0016] (2) The raw materials of fireproof aerogel insulation cotton mixture are dried by heating plates fixedly installed on both sides of the box to ensure the moisture content at the time of discharge. This avoids the increase in thermal conductivity and reduction in insulation effect of the fireproof aerogel insulation cotton due to the high moisture content. At the same time, it prevents chemical changes or microbial growth inside the large amount of fireproof aerogel insulation cotton due to the high moisture content, which would reduce the effective service life of the product.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: Please refer to Figure 1-4 As shown, this utility model is a mixing machine for producing fire-retardant aerogel insulation cotton, including a housing 1. A filtering mechanism is installed at the upper end of the housing 1. The filtering mechanism removes impurities and metal fragments mixed in the fire-retardant aerogel insulation cotton through a vibrating screen. The filtering mechanism includes a first filter screen 2 movably fitted inside the housing 1. The first filter screen 2 is used to filter the aerogel powder raw material. The diameter of the first filter screen 2 is selected according to the diameter of the aerogel powder. A vibrating motor 4 is fixed at the bottom of the first filter screen 2. A support rod 3 is fixed at the middle of the lower end of the first filter screen 2. A reciprocating motion is fixed at the end of the support rod 3. Device 5, the translational reciprocating device 5 is used to drive the first filter screen 2 to move horizontally back and forth. The lower end of the first filter screen 2 is equipped with a second filter screen 6. The second filter screen 6 is used to filter the fireproof aerogel insulation cotton fiber raw material. The diameter of the second filter screen 6 is selected according to the diameter of the fiber raw material. The second filter screen 6 has the same structure as the first filter screen 2. A first feed port 7 is opened on one side of the box body 1. The first feed port 7 is used for feeding flame retardants and adhesives. A second feed port 8 is opened at the upper end of the box body 1. The second feed port 8 is used for feeding aerogel powder and fiber raw materials. An outlet 9 is opened at the lower end of the box body 1.

[0025] The translational reciprocating device 5 includes a first servo motor 10, a lead screw 11, and a first slider 12. The first servo motor 10 drives the first slider 12 to reciprocate on the lead screw 11, and the first slider 12 drives the support rod 3 to reciprocate horizontally. It can quickly select different mixed raw material filter screens and also quickly remove impurities remaining on the filter screen. The upper end of the first slider 12 is fixedly connected to the support rod 3.

[0026] A through hole 13 is provided at the upper end of the outer side of the box 1. A slide rail 14 is provided at both the upper and lower ends of the through hole 13. A baffle 15 is slidably installed on the slide rail 14. The baffle 15 moves left and right on the slide rail 14 so that the vibration motor 4 is not blocked by the box 1 when it slides out of the box 1. A moving rod 16 is fixed in the middle of the baffle 15. The moving rod 16 can realize the sliding baffle 15 sliding left and right on the slide rail 14.

[0027] A second servo motor 17 is symmetrically fixedly installed on the outer side of the housing 1. A stirring shaft 18 is fixed on the output shaft of the second servo motor 17. A first stirring blade 19 and a fixing rod 20 are fixed on the upper surface of the stirring shaft 18. A second stirring blade 21 is fixed on the fixing rod 20. The second stirring blade 21 is set with different sizes. When the stirring shaft 18 rotates, the raw materials being stirred can form different stirring paths, so that the raw materials are fully stirred and the uniformity of the output is guaranteed.

[0028] The system employs a graded feeding design. Aerogel powder is first poured in through the second feed inlet 8. At this time, the vibration motor 4 is activated to vibrate and screen the first filter screen 2, removing impurities trapped within the aerogel powder. The aerogel powder falls into the housing 1, where the first servo motor 10 drives the first slider 12 to move horizontally on the lead screw 11, thereby moving the first filter screen 2 horizontally. A brush 30 fixed to the housing 1 cleans any remaining impurities from the first filter screen 2. Then, fiber material is poured in through the second feed inlet 8, and the vibration motor 4 is activated to vibrate and screen the second filter screen 6, removing fibers. Impurities and metal fragments mixed in the material are removed. Simultaneously, the second servo motor 17 is activated, which drives the stirring shaft 18 to rotate, thereby driving the first stirring blade 19 and the second stirring blade 21 to rotate, so as to mix the aerogel powder at the bottom and the fiber material falling from the top, so that the two are initially mixed. After the initial mixing, flame retardants, adhesives, etc. are added through the first feed port 7, so that the liquid raw materials can better penetrate into the initially mixed solid raw materials, improve the uniformity of the mixture, and then rotate fully to ensure that the raw materials are fully mixed and ensure the uniformity of the fireproof aerogel insulation cotton.

[0029] Example 2: Please refer to Figure 1-4 As shown, based on Embodiment 1, heating plates 22 are symmetrically fixedly installed on the inner side of the box 1. The heating plates 22 are used to quickly dry the mixed raw materials to avoid the fireproof aerogel insulation cotton from having too high a moisture content, which would increase the thermal conductivity and reduce the insulation performance. A protective shell 23 is fixed on the outer side of the heating plate 22. The protective shell 23 has multiple ventilation holes 24. The multiple ventilation holes 24 are used for ventilation and heat dissipation of the heating plate 22 to avoid local overheating of the heating plate 22 and damage to the equipment.

[0030] An inclined plate 25 is fixed to the bottom of the box 1. Fireproof aerogel insulation cotton is fed along the inclined plate 25. Bearing boxes 26 are symmetrically fixed at both ends of the bottom of the box 1. A push-pull rod 27 is movably installed inside the bearing box 26. A second slider 28 is fixedly connected to the end of the push-pull rod 27. A feeding plate 29 is fixed to the upper part of the second slider 28. The two feeding plates 29 can be spliced ​​together to complete the sealing of the feeding of the mixer. By moving the symmetrical push-pull rod 27, the second slider 28 is moved, thereby moving the feeding plates 29 at both ends. The feeding speed can be strictly controlled to avoid waste caused by feeding too much material at once.

[0031] A brush 30 is fixedly installed on the outer side of the housing 1 at the upper end of the first filter screen 2 and the second filter screen 6. When the filter screen moves horizontally, the brush 30 removes the impurities remaining on the filter screen after being vibrated.

[0032] The bottom of the box 1 is fixed with a base 31, and the side of the box 1 is provided with a ventilation hole 32.

[0033] The moisture content of the raw materials mixed with fire-retardant aerogel insulation cotton is tested. When raw materials with high moisture content enter the chamber 1, the mixture is dried by heating plates 22 fixed on both sides of the chamber 1. The heating plates 22 are cooled by ventilation holes 24 to avoid local heat concentration. The high moisture content of the fire-retardant aerogel insulation cotton leads to an increase in the thermal conductivity of the product and a decrease in its insulation performance. At the same time, when a large amount of fire-retardant aerogel insulation cotton is piled up, it is easy to cause chemical reactions or microbial growth, which reduces the service life of the product. After drying, the second slider 28 is moved by moving the symmetrical push-pull rod 27, which in turn moves the material feeding plates 29 at both ends. The feeding speed can be strictly controlled to avoid waste caused by feeding too much material at once.

[0034] The working principle of this utility model is as follows: A filtration mechanism installed inside the housing 1 removes impurities and metal fragments from the fire-resistant aerogel insulation cotton. A first feed inlet 7 and a second feed inlet 8 at the top of the housing 1 allow for graded feeding, enabling the aerogel powder, fiber raw materials, flame retardant, and adhesive to be added in batches, avoiding uneven mixing caused by uniform addition of raw materials. A second servo motor 17 drives the first stirring blade 19 and the second stirring blade 21 to rotate, thoroughly mixing the aerogel powder and the fiber material falling from the top. After initial mixing, the flame retardant and adhesive are added through the first feed inlet 7, allowing the liquid raw materials to better penetrate the initially mixed solid raw materials, improving the uniformity of the mixture. Simultaneously, the mixture is dried according to its initial moisture content to prevent chemical reactions or microbial growth caused by high moisture content, which could reduce the product's lifespan.

[0035] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
