Description

Technical Field

[0001] This utility model specifically relates to the field of flame retardant addition technology, and more specifically to a flame retardant addition device for sheet processing. Background Technology

[0002] The purpose of mixing flame retardants with fibers is to give the fiber materials good flame-retardant properties after subsequent processing into finished products (such as fiberboard, fire-resistant fabrics, etc.). By uniformly dispersing the flame retardant, it is ensured that all parts of the finished product can effectively delay the spread of fire and inhibit combustion when exposed to a fire source, thereby improving the overall fire safety level of the product.

[0003] Existing flame retardant addition devices use screw feeders to transport flame retardants, but this requires the flame retardant addition equipment and fiber addition equipment to be placed close together, making long-distance transmission impossible. Furthermore, each fiber addition device requires a separate flame retardant addition device, which increases the company's production costs and occupies a significant amount of space. Utility Model Content

[0004] The purpose of this invention is to provide a flame retardant adding device for sheet processing. One flame retardant adding device can dispense flame retardant to two fiber material adding devices, which not only reduces the number of flame retardant adding devices used, but also helps enterprises reduce costs; thus solving the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A flame retardant addition device for sheet metal processing includes a flame retardant addition mechanism. A pneumatic conveying pipe is provided below the flame retardant addition mechanism. A feeding fan is installed at one end of the pneumatic conveying pipe, and a bend is connected to the air outlet of the feeding fan. A first inclined pipe is connected through the bend. The first inclined pipe is also connected to a second inclined pipe through the bend.

[0007] A mixing pipe is connected to the middle of the second inclined pipe, and the other end of the mixing pipe is connected to the first fiber adding mechanism; a mixer is connected to the end of the second inclined pipe away from the bend; the bottom of the mixer has a discharge port, and its upper end is connected to the second fiber adding mechanism.

[0008] As a further technical solution of this utility model, the flame retardant adding mechanism includes a support frame, on which a silo is mounted; the bottom of the silo is connected to a connecting flange, and an inclined feeder is connected to the connecting flange.

[0009] As a further technical solution of this utility model, a quantitative feeder is connected to the bottom of the discharge end of the inclined feeder; the lower end of the quantitative feeder is connected to the pneumatic conveying pipe.

[0010] As a further technical solution of this utility model, the end of the wind-powered conveying pipe connected to the inclined feeder is L-shaped, and the end is also integrally provided with an air inlet pipe.

[0011] As a further technical solution of this utility model, the mixing pipe has a J-shaped pipe, the two ends of which are respectively connected to a second inclined pipe and a first fiber adding mechanism, wherein a first insert valve is provided at the end of the J-shaped pipe near the second inclined pipe; a discharge pipe is welded to the bend of the J-shaped pipe, and a second insert valve is provided on the discharge pipe.

[0012] The second inclined tube is equipped with a third slide valve at one end near the mixer.

[0013] As a further technical solution of this utility model, both the first fiber adding mechanism and the second fiber adding mechanism include a hopper cylinder, and a screw feeder is provided at the bottom of the hopper cylinder.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In use, the flame retardant adding mechanism, which stores the flame retardant, transports the flame retardant to the pneumatic conveying pipe. Under the pneumatic conveying of the feeding fan, the flame retardant is transported through the first and second inclined pipes to the mixing pipe or mixer, thereby achieving the mixing of the fiber material output by the first or second fiber adding mechanism with the flame retardant. This effectively reduces the number of flame retardant adding mechanisms required and lowers the enterprise's production costs. Furthermore, the pneumatic conveying method enables long-distance transmission.

In this utility model, flame retardant is stored in a silo, and the flame retardant can be conveyed by an inclined feeder set at the bottom; the setting of quantitative feeder and inclined feeder can realize precise quantitative discharge of flame retardant, strictly ensure the mixing ratio of flame retardant and fiber material, and improve the mixing effect.

[0017] 3. In this utility model, one flame retardant adding mechanism can achieve the coordinated use of two fiber adding mechanisms. Compared with traditional technology, this effectively reduces the number of flame retardant adding mechanisms used and lowers the production cost for enterprises; and it can be transported over long distances by means of wind power.

[0027] Please see Figure 1-5 In this embodiment of the present invention, a flame retardant adding device for sheet metal processing includes a flame retardant adding mechanism 1. A pneumatic conveying pipe 2 is provided below the flame retardant adding mechanism 1. A feeding fan 3 is installed at one end of the pneumatic conveying pipe 2, and a bend is connected to the air outlet end of the feeding fan 3. A first inclined pipe 4 is connected through the bend. The first inclined pipe 4 is also connected to a second inclined pipe 5 through the bend.

[0028] The second inclined tube 5 is connected to a mixing tube 6 at the middle position, and the other end of the mixing tube 6 is connected to the first fiber adding mechanism 8; the end of the second inclined tube 5 away from the bend is connected to a mixer 7; the bottom of the mixer 7 has a discharge port, and its upper end is connected to the second fiber adding mechanism 9.

[0029] By adopting the above technical solution, when in use, the flame retardant adding mechanism 1, which stores the flame retardant, transports the flame retardant to the pneumatic conveying pipe 2. Under the pneumatic conveying of the feeding fan 3, the flame retardant is transported through the first inclined pipe 4 and the second inclined pipe 5 to the mixing pipe 6 or the mixer 7, thereby realizing the mixing of the fiber material output by the first fiber adding mechanism 8 or the second fiber adding mechanism 9 with the flame retardant.

[0030] One flame retardant adding mechanism 1 can achieve the coordinated use of two fiber adding mechanisms. Compared with traditional technology, it effectively reduces the number of flame retardant adding mechanisms used and lowers the production cost of enterprises; and it can be transported over long distances by means of wind power.

[0031] In this embodiment, the flame retardant adding mechanism 1 includes a support 11, on which a silo 12 is mounted; the bottom of the silo 12 is connected to a connecting flange 13, and an inclined feeder 14 is connected to the connecting flange 13. A quantitative feeder 15 is connected to the bottom of the discharge end of the inclined feeder 14; the lower end of the quantitative feeder 15 is connected to the pneumatic conveying pipe 2.

[0032] By adopting the above technical solution, flame retardant is stored in silo 12, and the flame retardant can be conveyed by the inclined feeder 14 set at the bottom; the setting of quantitative feeder 15 and inclined feeder 14 can realize the precise quantitative discharge of flame retardant and strictly ensure the mixing ratio of flame retardant and fiber material.

[0033] In this embodiment, the end of the wind-powered conveying pipe 2 connected to the inclined feeder 14 is L-shaped, and the end is also integrally provided with an air inlet pipe 10.

[0034] By adopting the above technical solution, the air inlet pipe 10 is set up to facilitate the entry of external air when the feeding fan 3 is working, so as to quickly transport the flame retardant by air.

[0035] In this embodiment, the mixing pipe 6 has a J-shaped pipe 61, the two ends of which are connected to the second inclined pipe 5 and the first fiber adding mechanism 8, respectively. A first insert valve 62 is provided at the end of the J-shaped pipe 61 near the second inclined pipe 5.

[0037] By adopting the above technical solution, when the flame retardant is mixed with the fiber material in the first fiber adding mechanism 8, the third insert valve 64 is closed and the first insert valve 62 and the second insert valve 63 are opened. The flame retardant will enter the J-shaped pipe 61 through the second inclined pipe 5 and mix with the fiber material output from the first fiber adding mechanism 8, and then be discharged through the discharge pipe 65.

[0038] When the flame retardant is mixed with the fiber material in the second fiber adding mechanism 9, the third insert valve 64 is opened and the first insert valve 62 and the second insert valve 63 are closed.

[0040] The working principle of this utility model is as follows: When in use, the flame retardant adding mechanism 1, which stores the flame retardant, transports the flame retardant to the pneumatic conveying pipe 2. Under the pneumatic conveying of the feeding fan 3, the flame retardant is transported through the first inclined pipe 4 and the second inclined pipe 5 to the mixing pipe 6 or the mixer 7, thereby realizing the mixing of the fiber material output by the first fiber adding mechanism 8 or the second fiber adding mechanism 9 with the flame retardant.

[0041] When the flame retardant is mixed with the fiber material in the first fiber adding mechanism 8, the third insert valve 64 is closed and the first insert valve 62 and the second insert valve 63 are opened. The flame retardant will enter the J-shaped pipe 61 through the second inclined pipe 5 and mix with the fiber material output from the first fiber adding mechanism 8, and then be discharged through the discharge pipe 65.

[0042] When the flame retardant is mixed with the fiber material in the second fiber adding mechanism 9, the third insert valve 64 is opened and the first insert valve 62 and the second insert valve 63 are closed. The flame retardant will enter the mixer 7 through the second inclined pipe 5 and mix with the fiber material in the second fiber adding mechanism 9.

[0043] In this invention, one flame retardant adding mechanism 1 can achieve the coordinated use of two fiber adding mechanisms. Compared with traditional technology, this effectively reduces the number of flame retardant adding mechanisms used and lowers the production cost for enterprises. Furthermore, it can be transported over long distances via wind power.
