Description

Technical Field

[0001] This utility model relates to the field of glass fiber mat technology, specifically to a yarn recycling device for cyclone dust collectors. Background Technology

[0002] Fiberglass mat is a sheet-like product made by bonding continuous or chopped filaments together in an undirected manner using chemical adhesives or mechanical action. During the weaving process, waste or debris is drawn into a recycling and separation tower by wind power for waste recovery.

[0003] In conventional processes, a recovery water tank is set up below the cyclone dust collector. The waste separated by the cyclone dust collector enters the recovery water tank, absorbs water, becomes heavier, and settles in the recovery water tank. Meanwhile, the air is discharged from the exhaust port through the pipe above the cyclone dust collector. However, the waste needs to be carefully dried during the recycling process after absorbing water, which increases the number of steps and wastes a lot of manpower and resources. Furthermore, there are still broken yarns in the airflow separated by the cyclone dust collector, and direct discharge would waste raw materials. Utility Model Content

[0021] Example 1

[0022] This embodiment provides a yarn recovery device for a cyclone dust collector, the purpose of which is to solve the problem of incomplete recovery and separation of waste or fragments in existing recycling and separation towers used in felt weaving processes. (Refer to...) Figures 1-3 The specific structure of this embodiment will be described in detail below.

[0023] A yarn recycling device for a cyclone dust collector includes a first recycling bin 1 and a second recycling bin 2, both of which are hollow inside.

[0024] The inlet of the first recycling box 1 is connected to the ash discharge port below the cyclone dust collector 3, and the air inlet of the second recycling box 2 is connected to the air outlet of the cyclone dust collector 3; a recycling filter assembly is installed between the air inlet and the air outlet of the second recycling box 2.

[0025] In this embodiment, a first recycling box 1 is provided at the ash discharge port of the cyclone dust collector 3. The first recycling box 1 is hollow inside and is used to receive the waste or fragments separated by the cyclone dust collector 3. The waste or fragments can be directly recycled by drying the first recycling box 1 without the need for water absorption and sedimentation, thereby eliminating the step of drying the waste or fragments and saving time and a lot of manpower and resources.

[0026] A second recovery box 2 is installed at the air outlet of the cyclone dust collector 3. A recovery filter assembly is installed inside the second recovery box 2. The recovery filter assembly is connected to the air inlet of the second recovery box 2, so that the separated airflow of the cyclone dust collector 3 is filtered through the recovery filter assembly in the second recovery box 2 to filter the broken yarn in the airflow, thereby improving the recovery function of the separation tower, increasing the recycling rate, and saving raw materials.

[0027] Specifically, the air inlet of the first recycling box 1 is connected to the ash discharge port below the cyclone dust collector 3 through the telescopic pipe 4.

[0028] Both ends of the telescopic pipe 4 are provided with a first connecting flange 41. One first connecting flange 41 is connected to the second connecting flange 31 reserved on the ash discharge port below the cyclone dust collector 3; the other first connecting flange 41 is connected to the third connecting flange 11 reserved at the inlet of the first recycling box 1.

[0029] In this embodiment, the first recycling bin 1 and the cyclone dust collector 3 are connected by a telescopic pipe 4. Both ends of the telescopic pipe 4 are provided with first connecting flanges 41. A second connecting flange 31 is reserved on the ash discharge port below the cyclone dust collector 3, and a third connecting flange 11 is reserved at the inlet of the first recycling bin 1. The two first connecting flanges 41 are respectively connected to the second connecting flange 31 and the third connecting flange 11 by bolts. Thus, the first recycling bin 1 and the cyclone dust collector 3 are connected by the telescopic pipe 4, which facilitates the connection between the first recycling bin 1 and the cyclone dust collector 3.

[0030] Optionally, sealing strips may be provided between the first connecting flange 41 and the second connecting flange 31 and between the first connecting flange 41 and the third connecting flange 11.

[0031] Specifically, a recycling port 12 is provided on the side wall of the first recycling bin 1, and a sealing door 13 is movably installed inside the recycling port 12. A fixed step 14 is provided inside the recycling port 12, and a sealing strip is provided between the fixed step 14 and the sealing door 13.

[0032] In this embodiment, the first recycling bin 1 can be cylindrical, and the recycling opening 12 is rectangular. The rectangular recycling opening 12 is disposed on the side wall of the first recycling bin 1. A sealing door 13 can be hinged to one side of the recycling opening 12, and there is a suitable distance between the other side of the recycling opening 12 and the sealing door 13 so that the sealing door 13 can be opened and closed.

[0033] A fixed step 14 is provided on the inner circumferential side of the recycling port 12, and a sealing strip is provided on the side wall of the sealing door 13, so that the sealing door 13 is sealed when closed.

[0034] Specifically, the recycling filter assembly includes a fourth connecting flange 51 connected to the air inlet of the second recycling box 2, and a fixed bracket 52 installed in the rear section of the second recycling box 2; the fourth connecting flange 51 and the fixed bracket 52 are connected by four connecting rods 53; a first filter screen 54 is provided on the four connecting rods 53 and in the middle of the fixed bracket 52.

[0035] A second filter 55 is provided between the fixed bracket 52 and the air outlet of the second recycling box 2.

[0036] In this embodiment, the fixed bracket 52 consists of four fixed rods arranged in a "well" shape. The ends of the fixed rods of the fixed bracket 52 are fixed to the inner wall of the second recycling box 2. A first filter screen 54 is provided in the middle of the fixed bracket 52. The through hole in the middle of the four connecting flanges 51 is concentrically arranged with the air inlet of the second recycling box 2. The fourth connecting flange 51 is installed inside the air inlet of the second recycling box 2, and the four connecting rods 53 of the fixed bracket 52 are connected to the fourth connecting flange 51. The first filter screens 54 are provided between each pair of the four connecting rods 53. Thus, the separated airflow of the cyclone dust collector 3 entering from the air inlet of the second recycling box 2 passes through the first filter screens 54 to filter the broken yarn in the airflow, trapping the broken yarn in the recycling filter assembly.

[0037] A second filter 55 is provided between the fixed bracket 52 and the air outlet of the second recycling box 2. The mesh size of the second filter 55 is smaller than that of the first filter 54, so that the second filter is filtered a second time to trap the yarn fragments. The separated airflow after trapping the yarn fragments is discharged through the air outlet of the second recycling box 2.

[0038] Although the specific embodiments of the utility model have been described in detail with reference to the accompanying drawings, this should not be construed as limiting the scope of protection of this patent. Various modifications and variations that can be made by those skilled in the art without inventive effort within the scope described in the claims still fall within the scope of protection of this patent.
