Description

Technical Field

[0001] This utility model relates to the field of polyester-cotton yarn processing technology, specifically to a dust removal device for conveying polyester-cotton yarn. Background Technology

[0002] Polyester fiber has high strength. When blended with cotton yarn, polyester-cotton yarn becomes even stronger than pure cotton yarn. This makes fabrics made from polyester-cotton yarn more durable and less prone to damage, and therefore it is widely used.

[0003] A search revealed a functional dust removal device for conveying polyester-cotton yarn, disclosed in Chinese Patent Publication No. CN216006166U. This device involves sequentially passing the blended yarn through a dust collection tube, a conveying pipe, and a bladeless fan body. The yarn enters the conveying pipe via a guide tube, and the airflow generated by the fan assembly in the bladeless fan body is discharged from the exhaust port of the airflow nozzle, effectively blowing dust from all directions onto the yarn. This significantly improves the dust removal effect.

[0004] However, similar to the above-mentioned functional polyester-cotton yarn conveying dust removal device, which uses the bag filter principle, when the dust passes through the filter bag, it is blocked on the outer surface of the filter bag, and the purified gas is discharged from the outlet. In the dust removal and filtration process, larger particles and impurities will clog the filter bag, causing an increase in filtration resistance, which will affect the filtration effect and the service life of the device. Therefore, a new solution is needed to solve this problem. Utility Model Content

[0005] The aforementioned background technology addresses the shortcomings and defects of existing technologies, such as the common use of bag filters which easily leads to clogging, affecting filtration efficiency and the lifespan of the device.

[0006] The dust removal device for conveying polyester-cotton yarn disclosed in this utility model includes a first outer shell, a second outer shell installed on one side of the first outer shell, a dust removal component installed on the first outer shell, an air outlet pipe installed on the second outer shell, a filter bag installed at the lower end of the air outlet pipe, a filter screen installed above the filter bag, the filter screen being slidably disposed with the air outlet pipe via a sliding shell, a limit plate being installed above the sliding shell, an elastic component being disposed between the limit plate and the air outlet pipe, and a baffle being slidably disposed at the upper end of the air outlet pipe.

[0007] Furthermore, the elastic component includes a fixing block, which is installed on the outer wall of the air outlet duct. The fixing block is connected to the limiting plate by a telescopic rod, and the telescopic rod is fitted with a spring.

[0008] Furthermore, guide rods are symmetrically arranged on both sides of the telescopic rod. One end of the guide rod is installed on the limiting plate, and the other end of the guide rod passes through the fixing block. The guide rod is slidably arranged with the fixing block.

[0009] Furthermore, a fixing bolt is provided on the sliding shell, the fixing bolt passes through the filter screen, and a nut is provided on the fixing bolt, the nut being threadedly connected to the fixing bolt.

[0010] Furthermore, the filter bag is provided with a collar at its upper end, and a sealing gasket is provided on the inner side of the collar. The collar is fitted onto the air outlet pipe, and a retaining plate is rotatably installed on the air outlet pipe. The retaining plate is engaged with the collar.

[0011] Furthermore, push plates are provided on both sides of the sliding shell, and an elastic component two is provided between the push plate and the air outlet pipe. The elastic component two has the same structure as the elastic component one.

[0012] Furthermore, the dust removal component includes a fan, which is mounted on the outer casing, and an air guide shroud is installed on the inner wall of the outer casing at the position corresponding to the fan.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by incorporating components such as a filter screen, a sliding shell, and a limiting plate, blows dust and impurities off the polyester-cotton yarn during operation. The dust then enters the outlet duct. Through the cooperation of the filter screen, sliding shell, and limiting plate components, the filter screen is confined inside the outlet duct. The filter screen performs preliminary filtration of the dust-laden gas, removing larger particles and impurities, reducing the burden on the filter bag, thereby improving the overall dust removal efficiency and extending the service life of the filter bag.

[0015] 2. This utility model is equipped with a second elastic component, a push plate, a nut, and a fixing bolt. During operation, the operator drives the limiting plate component to separate from the sliding shell. At this time, the second elastic component and the push plate component cooperate with each other, thereby pushing the sliding shell component to slide automatically on the air outlet pipe, which facilitates the operator to move the sliding shell. The filter screen is installed on the sliding shell by the cooperation between the nut and the fixing bolt. By removing the nut, the filter screen is released from fixation, so that the filter screen can be disassembled and replaced. Attached Figure Description

Detailed Implementation

[0023] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0024] Please see Figure 1 , Figure 5 The dust removal device for conveying polyester-cotton yarn of this utility model includes a first outer shell 1, a second outer shell 2 installed on one side of the first outer shell 1, a sealing gasket between the second outer shell 2 and the first outer shell 1, one end of the second outer shell 2 and the first outer shell 1 being rotatably connected by a hinge, and the other end being fixedly connected by a buckle, a dust removal component being provided on the first outer shell 1, an air outlet pipe 5 being installed on the second outer shell 2, a filter bag 6 being provided at the lower end of the air outlet pipe 5, a filter screen 9 being provided above the filter bag 6, and the filter screen 9 being slidably connected to the air outlet pipe 5 via a sliding shell 10. A sealing gasket is provided between the sliding shell 10 and the air outlet pipe 5. A limiting plate 14 is provided above the sliding shell 10. The lower end of the limiting plate 14 is chamfered. An elastic component 16 is provided between the limiting plate 14 and the air outlet pipe 5. A baffle 13 is slidably provided at the upper end of the air outlet pipe 5. A sealing ring is provided between the baffle 13 and the air outlet pipe 5. By driving the baffle 13 to move downward, the air outlet pipe 5 can be closed. By driving the baffle 13 to move upward, the air outlet pipe 5 can be opened, allowing air to circulate.

[0025] During operation, the dust and impurities on the polyester-cotton yarn are blown away by the dust removal components and then enter the air outlet duct 5. First, the dust and impurities pass through the filter screen 9, which blocks larger particles and impurities. Then, the smaller impurities and dust enter the filter bag 6 for secondary filtration, and the impurity-free air is discharged.

[0026] like Figure 1 , Figure 2 As shown, the elastic component 16 includes a fixing block 161, which is installed on the outer wall of the air outlet duct 5. The fixing block 161 is connected to the limiting plate 14 by a telescopic rod 164. The telescopic rod 164 is fitted with a spring 162. When the filter screen 9 needs to be cleaned, the operator drives the limiting plate 14 to move upward and separate it from the sliding shell 10, thereby releasing the restriction on the sliding shell 10. Then the sliding shell 10 is pulled out, and the filter screen 9 inside the sliding shell 10 can be cleaned. For installation, the sliding shell 10 can be pushed directly into the air outlet duct 5.

[0027] In this embodiment, guide rods 163 are symmetrically arranged on both sides of the telescopic rod 164. One end of the guide rod 163 is installed on the limiting plate 14, and the other end of the guide rod 163 passes through the fixing block 161. The guide rod 163 is slidably arranged with the fixing block 161. The guide rod 163 restricts the movement direction of the limiting plate 14, thereby improving the stability of the limiting plate 14 during operation.

[0028] Combination Figure 1 , Figure 5 As shown, multiple air outlet pipes 5 are provided, and the distance between multiple air outlet pipes 5 is greater than the length of the sliding shell 10. A fixing bolt 12 is provided on the sliding shell 10. The fixing bolt 12 passes through the filter screen 9. A nut 11 is provided on the fixing bolt 12. The nut 11 is threadedly connected to the fixing bolt 12. After the operator pulls out the sliding shell 10, he drives the nut 11 on the fixing bolt 12 to rotate and separate it from the fixing bolt 12, thereby releasing the restriction on the filter screen 9 and realizing the removal of the filter screen 9. Then, by reversing the operation, a new filter screen 9 can be installed on the sliding shell 10.

[0029] The filter bag 6 is provided with a collar 7 at the upper end, and a sealing gasket is provided on the inner side of the collar 7. The collar 7 is fitted onto the air outlet pipe 5. A retaining plate 8 is rotatably installed on the air outlet pipe 5. The retaining plate 8 is engaged with the collar 7. By driving the retaining plate 8 to rotate upward and separate it from the collar 7, the restriction on the collar 7 can be released, and the filter bag 6 can be removed for replacement.

[0030] like Figure 1 , Figure 2As shown, push plates 15 are provided on both sides of the sliding shell 10. An elastic component 2 17 is provided between the push plate 15 and the air outlet pipe 5. The elastic component 2 17 has the same structure as the elastic component 16. When the limiting plate 14 releases the restriction on the sliding shell 10, the elastic component 2 17 drives the push plate 15 to move. The push plate 15 pushes the sliding shell 10 to move. When the operator drives the sliding shell 10 to close, the sliding shell 10 pushes the push plate 15 to move. The push plate 15 pushes the elastic component 2 17 to store force.

[0031] Combination Figure 1 , Figure 3 , Figure 4 As shown, the dust removal component includes a fan 3, which is mounted on the outer casing 1. A guide hood 4 is installed on the inner wall of the outer casing 1 at the corresponding position of the fan 3. The fan 3 is controlled to blow air to the guide hood 4, which guides the air onto the polyester-cotton yarn and blows away the dust and impurities on the polyester-cotton yarn, thus achieving a cleaning effect.
