Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of elastic felt processing equipment, in particular to a kind of powdering machine for elastic felt processing. BACKGROUND

[0002] With the development needs of today's society, the application field of natural gas is also more and more extensive. At room temperature, the volume of LNG (liquefied natural gas) is only 1 / 625 of that in gaseous state, and it is stored in LNG low-temperature storage tanks in liquefied form at a temperature of about -162℃. Elastic felt has outstanding advantages in LNG storage application. It not only ensures the structural integrity and safety of the storage tank, but also improves its thermal insulation and fireproof performance, and adapts to extreme working environments. In order to improve the thermal insulation effect of elastic felt, a binder is added during the preparation of glass fiber cotton to improve the thermal insulation effect of elastic felt.

[0003] The traditional binder layout structure uses a brush scraping method during layout. The binder is swept onto the guide plate by the brush and then falls onto the glass fiber. Although this method can achieve the purpose of adding binder to the glass fiber and improving its thermal insulation strength, the falling is not uniform, which can easily lead to uneven thermal insulation area during the forming stage. The existing technology sets the entire material spreading device on a horizontally moving structure to improve the uniformity of material spreading. However, on the one hand, the moving material spreading device cannot adapt to the glass fiber which is also in a moving state, which can still lead to uneven material distribution. On the other hand, the moving material spreading device is difficult to control in terms of direction, and the direction of the falling particles is difficult to control, which cannot achieve precise control. SUMMARY

[0004] The utility model provides a kind of powdering machine for elastic felt processing, can the binder particle evenly dispersed to each area of glass fiber felt, and during spreading material, it can guarantee that particle enters the inside of glass fiber felt and not overflow in this process, even in the later stage of web formation, it can guarantee that the whole surface is evenly felt structure, can effectively solve the above problems.

[0005] The utility model is implemented as follows:

[0006] A kind of powdering machine for elastic felt processing is arranged above the belt scale, the upper end of the belt scale is provided with a mounting bracket, comprising:

[0007] Front and rear section distribution structure, the front and rear section distribution structure includes a powdering cylinder arranged on the mounting bracket, the powdering cylinder is divided into several chambers, all chambers of the powdering cylinder are connected to a transmission cavity, the transmission cavity is connected to a division cylinder, the front and rear ends of the division cylinder are provided with several equal division pipes, the chambers on the powdering cylinder input particles to the transmission cavity, and the particles are evenly divided into each equal division pipe on the division cylinder through the transmission cavity, so that all the equal division pipes evenly sprinkle particles on the glass fiber;

[0008] The structure comprises an arc-shaped material guiding hopper arranged outside the equal distribution pipe, two powder guiding cavities arranged at the two ends of the inner side of the arc-shaped material guiding hopper, and a wind guiding pipe arranged at the middle part of the arc-shaped material guiding hopper, and the end position of the wind guiding pipe is connected with a dispersing piece arranged at the bottom end of the arc-shaped material guiding hopper.

[0009] As a further improvement, the equal distribution cylinder is a cylinder structure, and the equal distribution cylinder comprises a solid base, a material distribution shovel integrally formed above the solid base, and a material distribution cavity connected to the outer side of the solid base.

[0010] As a further improvement, the equal distribution pipe comprises a material storage cavity connected with the solid base, a dosing piece arranged at the front end of the material storage cavity, and a material distribution cavity pipe connected with the rear end of the material storage cavity.

[0011] As a further improvement, the dosing piece comprises a rotating shaft movably inserted into the material storage cavity, a turnover plate connected to the outer side of the rotating shaft, and a rotating motor arranged outside the material storage cavity and used for driving the turnover plate, and a time relay is arranged on the rotating motor.

[0012] As a further improvement, the material distribution cavity pipe is a V-shaped structure, the top end of the V-shaped structure is communicated with the material storage cavity, and the two openings of the material storage cavity are communicated with the powder guiding cavities.

[0013] As a further improvement, the arc-shaped material guiding hopper comprises an outer extension plate connected with the top outer edge of the material distribution cavity, an arc-shaped surface connected below the outer extension plate, and two sealing plates connected with the arc-shaped surface at the two ends of the arc-shaped surface.

[0014] As a further improvement, the arc-shaped surface is provided with a Venturi structure, the Venturi structure comprises a flow passage section connected with the wind guiding pipe and a converging section, the converging section is communicated with the powder guiding cavities, and when the input wind is input into the converging section through the flow passage section, part of the powder in the powder guiding cavities is sucked and directly sprayed into the interior of the glass fiber.

[0015] As a further improvement, the dispersing piece comprises an elongated frame connected with the powder guiding cavities and the lower end of the arc-shaped material guiding hopper, a middle section inclined plate arranged at the middle part of the inner side of the elongated frame, and side direction inclined plates arranged at the two sides of the middle section inclined plate and connected with the elongated frame.

[0016] The beneficial effects of the utility model are as follows:

[0017] In the existing adhesive discharging structure, a brush is usually used to scrape the adhesive downward, so as to realize uniform dispersion of the adhesive. However, the adhesive is mostly in the form of powder, and the powder is easy to splash when scraped downward by the brush, resulting in loss and uneven distribution of the powder. Therefore, the present application divides the whole powder scattering process into two stages by the front and rear section material distribution structure. After the powder enters the powder scattering cylinder and the transmission cavity, it is stored in the front and rear two equal distribution pipes. After the equal distribution pipes are filled with powder, the first scattering is performed by the equal distribution pipe at the front end position. The glass fiber after the first scattering moves to the equal distribution pipe at the rear end position by the belt scale, and the second scattering is performed by the equal distribution pipe at the rear end position. The positions of the two scattering are staggered, so as to ensure the uniformity of the powder scattering.

[0018] When the powder enters the equal distribution cylinder, it needs to be discharged uniformly in two directions, so the present application is provided with a material distribution shovel on the equal distribution cylinder. The material distribution shovel divides the powder falling in the middle into two parts, so that the equal distribution pipes at both ends can store enough powder, and the powder can be discharged multiple times to avoid the phenomenon of being concentrated in a certain area.

[0019] During the discharging process of the equal distribution pipe, the belt scale needs to be measured at all times, so the discharging amount of each equal distribution pipe in each area is fixed. Therefore, the present application is provided with a quantitative part on each equal distribution pipe. The design of the quantitative part enables each equal distribution pipe to output a fixed amount of powder, so as to fix the amount of powder in each area, thereby promoting the uniform distribution of the adhesive in each area.

[0020] The powder after the quantitative process needs to be input into the flow guide flushing structure. In order to directly cooperate with the two powder guide cavities, the present application sets the cloth distribution cavity pipe into a V-shaped structure. The powder after the quantitative process is guided out into the flow guide flushing structure by the bifurcated middle section, so as to ensure that the powder can be segmented to cooperate with the glass fiber, and the powder can be more uniformly distributed in the glass fiber.

[0021] Although the powder discharged from the equal distribution pipes at both ends can realize secondary scattering of the powder and as much as possible uniform coverage, the powder is still easy to splash in the air and fly around. Moreover, the scattered powder can only float on the surface of the glass fiber, and is extremely easy to be separated in the later web forming process and float inside the airflow web forming box, resulting in poor thermal insulation performance of the formed elastic felt. Therefore, the present application is provided with a flow guide flushing structure on the basis of the front and rear section material distribution structure. The powder in the equal distribution pipes enters the powder guide cavities at both ends to be naturally distributed. At the same time, the air inlet pipe introduces air into the arc-shaped material guide hopper to produce a Venturi effect to suck part of the powder in the powder guide cavities, so that part of the powder can penetrate into the deep part of the glass fiber, thereby making the adhesive of the glass fiber more uniformly distributed, and further improving the production quality.

[0022] Since the whole flow guide material flushing structure needs to be ventilated and the powder material needs to be distributed, the space in the whole flow guide material flushing structure needs to be closed, therefore, the arc-shaped material guide hopper is first arranged as an arc-shaped surface, facilitating the material to be discharged, and the arc-shaped surface is closed at the outer side and the top, and is closed by the outer extension plate and the sealing plate, so that the whole arc-shaped material guide hopper is closed and arranged, and only the area at the bottom is discharged, so that a uniform falling surface can be formed, and overflow from the side direction is avoided.

[0023] In the process of the powder sliding down from the arc-shaped material guide hopper, the powder is divided into two sections for sliding down, one section is the sliding down of the powder guide cavity itself, and the other section is the accelerated sliding down in the Venturi structure of the arc-shaped surface. Since the air duct is connected to the Venturi structure and the diameter of the air duct changes, part of the powder in the powder guide cavity can be sucked into the air duct, so that part of the powder is input into the interior of the glass fiber in a high kinetic energy mode, so that the adhesive is distributed in the interior and the exterior of the glass fiber. Even in the air-laid box, on the basis that the adhesive is already distributed relatively uniformly, the formation of the thick felt is more favorable.

[0024] Regardless of the powered powder or the unpowered powder, the powder is finally output from the bottom of the arc-shaped material guide hopper, and in order to ensure uniformity, the dispersion member at the bottom of the arc-shaped material guide hopper is divided into a middle section inclined piece and a lateral inclined piece. The middle section inclined piece corresponds to the position of the Venturi structure, so that the accelerated powder can be smoothly output, and the lateral inclined piece corresponds to the naturally falling powder in the powder guide cavity, so that the naturally falling powder is more uniformly distributed under the guidance, and a uniform adhesive distribution surface is formed.

[0035] In the embodiment, the glass fibers used are not a single type, but a mixture of two types of glass fibers. Both types of glass fibers are added to the bale opener 10, and after multiple processing steps, the elastic felt is obtained.

[0036] The binder and the powder mentioned in the embodiment are both phenolic resin, which is a commonly used binder. In this case, the binder is in powder form, and it will completely dissolve in the glass fibers during the heating stage after the thick felt is formed.

[0038] In the existing adhesive discharging structure, a brush is usually used to scrape the adhesive downward, so as to realize uniform dispersion of the adhesive, but the adhesive is mostly in the form of powder, and the powder is easy to splash when scraped downward by the brush, so that the powder is lost and not uniformly dispersed, therefore, the present application divides the whole powder scattering process into two stages by the front and rear section material distribution structure 71, stores the powder in the front and rear two equal distribution pipes 714 after the powder enters the powder scattering cylinder 711 and the transmission cavity 712, and first carries out the first powder scattering through the equal distribution pipe 714 at the front end position after the equal distribution pipe 714 stores the full powder, the glass fiber after the first powder scattering reaches the equal distribution pipe 714 at the rear end position after moving on the belt scale 60, and carries out the second powder scattering through the equal distribution pipe 714 at the rear end position, and the positions of the two powder scatterings are staggered, so as to ensure the uniformity of the powder scattering.

[0039] When the powder enters the equal division cylinder 713, the powder needs to be evenly divided into two parts because it needs to be discharged in two directions, therefore, the equal division cylinder 713 of the embodiment is a cylinder structure, the equal division cylinder 713 comprises a solid base 7131, the solid base 7131 is integrally formed with a material distribution shovel 7132 above, the solid base 7131 is connected with a material distribution cavity 7133 outside, the material distribution shovel 7132 divides the material distribution cavity 7133 into two chambers in front and rear, the equal division cylinder 713 is provided with the material distribution shovel 7132, the powder falling in the middle is divided into two parts by the material distribution shovel 7132, so that the equal distribution pipe 714 at both ends can store enough powder, and the powder can be discharged multiple times to avoid the phenomenon of being concentrated in a certain area.

[0040] In the discharging process of the equal distribution pipe 714, the belt scale 60 needs to be measured at all times, so the discharging amount of the equal distribution pipe 714 in each area is fixed, therefore, the equal distribution pipe 714 of the embodiment comprises a storage cavity 7141 connected with the solid base 7131, the front end of the storage cavity 7141 is provided with a dosing device 7142, and the rear end of the storage cavity 7141 is connected with a cloth distribution cavity pipe 7143, each equal distribution pipe 714 is provided with the dosing device 7142, the dosing device 7142 allows each equal distribution pipe 714 to output a fixed amount of powder, so that the powder amount in each area is fixed, thereby promoting the uniform distribution of the adhesive in each area.

[0041] The quantitative piece 7142 is quantified according to the time of powder passing during quantification, specifically, the quantitative piece 7142 comprises a rotating shaft 71421 movably inserted in the storage cavity 7141, the rotating shaft 71421 is connected with a turnover plate 71422 on the outside, the turnover plate 71422 is driven by a rotating motor 71423 arranged outside the storage cavity 7141, the rotating motor 71423 is provided with a time relay, the time relay starts timing after each rotation of the rotating motor 71423, so that a fixed amount of powder can be released in a cycle, thereby realizing more accurate material control.

[0042] The quantified powder needs to be input into the flow guide flushing structure, in order to directly cooperate with the two powder guide cavities 722, the material distribution cavity pipe 7143 of the embodiment is a V-shaped structure, the top end of the V-shaped structure is communicated with the storage cavity 7141, and the two openings of the storage cavity 7141 are communicated with the powder guide cavities 722, the material distribution cavity pipe 7143 is arranged in a V-shaped structure, the quantified powder is guided out into the flow guide flushing structure in a bifurcated manner, so that the powder can be segmented and cooperated with the glass fiber, and the powder is more evenly distributed in the glass fiber.

[0043] The powder discharged from the two-end distribution pipe 714 can realize secondary powder scattering and as evenly cover as possible, but it is still easy to splash in the air and fly around, and the scattered powder can only float on the surface of the glass limit, and is extremely easy to be separated in the later web forming process and float in the internal of the air-laid box 80, resulting in poor thermal insulation performance of the formed elastic felt, therefore, the utility model sets the flow guide flushing structure on the basis of the front and rear segment distribution structure 71, the powder of the distribution pipe 714 enters the powder guide cavities 722 from both ends and is naturally distributed, at the same time, the air duct 723 introduces air and makes the air enter the arc-shaped material guide hopper 721 to generate a Venturi effect to suck part of the powder in the powder guide cavities 722, so that part of the powder can be deeply inserted into the glass fiber, thereby making the adhesive of the glass fiber more evenly distributed, and further improving the production quality.

[0044] Since the whole flow guide and material flushing structure needs to be ventilated and the powder material needs to be distributed, the space in the whole flow guide and material flushing structure needs to be closed. Therefore, the arc-shaped material guide hopper 721 of the embodiment comprises an outer extension plate 7211 connected with the top outer edge of the material distribution cavity 7133. The lower side of the outer extension plate 7211 is connected with an arc-shaped surface 7212.

First, the arc-shaped material guide hopper 721 is arranged as the arc-shaped surface 7212 to facilitate the material to be discharged. The outer side and the top of the arc-shaped surface 7212 are closed. The whole arc-shaped material guide hopper 721 is closed through the outer extension plate 7211 and the sealing plates 7213, so that the material is discharged only from the bottom area, thereby forming a uniform falling surface and avoiding overflow from the side direction.

[0045] In the process of the powder sliding down from the arc-shaped material guide hopper 721, a Venturi structure 7214 is arranged in the arc-shaped surface 7212.

When the air input through the flow-through section 72141 into the converging section 72142, part of the powder in the powder guide cavity 722 is sucked and directly sprayed into the interior of the glass fiber. The powder is divided into two sections to slide down. One section is the sliding down of the powder guide cavity 722 itself, and the other section is the accelerated sliding down in the Venturi structure 7214 of the arc-shaped surface 7212. The air is input into the Venturi structure 7214 through the air guide pipe 723. Due to the change of the pipe diameter and the communication with the powder guide cavity 722, part of the powder in the powder guide cavity 722 is sucked, so that a part of the powder is input into the interior of the glass fiber in a high kinetic energy mode, thereby enabling the interior and the exterior of the glass fiber to have the distribution of the adhesive. Even in the air-laid box 80, on the basis of the relatively uniform distribution of the adhesive itself, it is more conducive to the formation of the thick felt.

[0046] Regardless of the powered powder or the unpowered powder, finally, the powder is output from the bottom of the arc-shaped material guide hopper 721. In order to ensure uniformity, the dispersing member 724 comprises an elongated frame 7241 connected with the powder guide cavity 722 and the lower end of the arc-shaped material guide hopper 721.

The middle inclined piece 7242 corresponds to the position of the Venturi structure 7214, so that the accelerated powder can be smoothly output. The lateral inclined piece 7243 corresponds to the naturally falling powder in the powder guide cavity 722, so that the naturally falling powder is more uniformly distributed under the guidance, thereby forming a uniform adhesive distribution surface.
