Description

Technical Field

[0001] The utility model relates to a dust collector which is suitable for a fluff stripping process. Background Art

[0002] In the depilation process, fans are widely used to provide power for material transportation in the depilation process, so as to transport the materials to the corresponding places. While the fan provides power, some fine materials will inevitably flow to the fan through the discharger, and then enter the fan through the fan suction port, and then be discharged from the fan outlet.

[0003] In the depilation process, some of the fine materials discharged by the fan are mainly composed of dust and short fibers. In order to protect the environment of workshops and factories and to meet the relevant national standards for atmospheric emissions, corresponding dust removal equipment is required to filter the materials discharged by the fan.

[0004] Since the fine materials discharged by the fan in the depilation process contain short fibers, the dust removal of the impurity gas discharged by the fan is generally carried out by a bag filter (usually a pulse bag filter). However, the short fibers are very easy to get stuck on the bag and are difficult to be removed by the bag filter's own dust removal action. Therefore, as the short fibers accumulate, the bag filter will often fail in a relatively short period of time.

[0005] In view of this, in the traditional depilation process, it is often necessary to set up a cyclone dust collector in the front stage of the bag filter to separate the short lint and some dust particles with relatively large specific gravity through sedimentation, so as to avoid the failure of the bag filter due to excessive accumulation of short lint. However, there is a lack of research on how to set up a cyclone in the front stage of the bag filter and the configuration of the cyclone, and the cleaning effect of short lint needs to be further improved. Utility Model Content

[0006] In view of this, the purpose of the utility model is to provide a dust collector suitable for a stripping process which is more suitable for separating short fibers.

[0007] In an embodiment of the utility model, a dust collector suitable for a depilation process is provided, the dust collector comprising:

[0008] A plurality of Shakers, the cut-in pipes of the plurality of Shakers are connected to the corresponding main air ducts of the fans;

[0009] The bag filter is equipped with an exhaust manifold for introducing gas, and the air inlet end of the exhaust manifold is used to be connected to the exhaust pipe of the Shaklon; and

[0010] The ash discharge auger receives the ash hopper of the ash separator to discharge the ash separated by the ash separator.

[0011] Optionally, the number of the shakrons is an even number, no more than eight and no less than two.

[0012] Optionally, the Shakrons are arranged in a row-column matrix;

[0013] A collecting hopper with a larger top and a smaller bottom is provided at the lower side of the row and column matrix, and the upper end of the collecting hopper is used to directly receive the ash hopper;

[0014] The discharge port at the lower end of the collecting hopper is connected with the inlet of the debris removal auger.

[0015] Optionally, the shaker is a shaker with a diffusion box at the lower end.

[0016] Optionally, the angle of the lower cone of the diffusion box is 50°~60°, the height of the diffusion box is 1200~1280 mm, and the large base diameter of the lower cone of the diffusion box is 1550~1650 mm.

[0017] Optionally, the inlet diameter of the diffusion box is 1.2 times the outlet diameter.

[0018] Optionally, the height of the barrel of the Shakron is smaller than the height of the cone.

[0019] Optionally, the barrel height of the Shakron is 0.73 to 0.75 times the cone height.

[0020] Optionally, the height of the cylinder is 1.34 times the diameter of the cylinder.

[0021] Optionally, the bag dust collector is a pulse bag dust collector.

[0022] After research, it was found that relatively small-sized shakrons are more likely to separate small and light components. Relatively speaking, short fibers are components with large specific surface areas. Traditional dust collectors suitable for depilation processes are generally equipped with only one shakron, resulting in relatively more short fibers entering the bag filter. Short fibers are precisely the materials that cannot be automatically removed by the bag filter, which may cause the bag filter to fail in a relatively short period of time and also lose a certain amount of short fibers. In view of this, in an embodiment of the utility model, multiple shakrons are provided. Under the same flow rate, the monomer specifications of multiple shakrons used in parallel can be relatively small, thereby making it easier to separate short fibers. When the short fiber content in the exhaust gas is further reduced, the bag filter can have a longer service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Since both the Shaklon 5 and the bag dust collector are conventional configurations in this field, their working principles are not described in detail. In the embodiments of the utility model, emphasis is placed on the selection of the Shaklon 5 and the adaptation of its quantity.

[0029] Compared with the situation of using a single shaker 5 in the prior art, a plurality of shakers 5 are provided in the embodiment of the utility model. If the processing air volume is 33,956 cubic meters per hour, when processed by a single shaker 5, the processing air volume of the single shaker 5 needs to be no less than 33,956 cubic meters per hour. If four shakers 5 connected in parallel are used for processing, the processing volume of each shaker 5 only needs to be no less than 8,489 cubic meters per hour. Shackles 5 of relatively smaller specifications can be selected. Based on the consideration of suitability, it is easier to separate relatively fine materials, such as short fibers. This has been explained in the previous text and will not be repeated here.

[0030] In view of this, in the embodiment of the utility model, a plurality of relatively small-sized Shakrons 5 are used to better separate the short fibers, which can reduce the impact on the subsequent stages such as the pulse bag dust collector 9 on the one hand, and further separate more short fibers from the recycled materials on the other hand.

[0031] It should be noted that since the Shakron 5 is connected through a pipeline, the parallel connection of the Shakron 5 conforms to the general configuration of the pipeline components in implementation. Figure 3 and Figure 4 As shown in the figure, the Shaklong 5 has three openings, two of which are located on the cylinder 12 at the upper part of the Shaklong 5, wherein the cut-in pipe 6 is its air inlet pipe, and the exhaust pipe 7 generally penetrates into the cylinder 12 to a certain extent, which has a definite purpose in this field and is defined as the exhaust pipe insertion depth.

[0032] The parallel connection is the parallel connection of the aforementioned cut-in pipe 6 on the intake pipe side, such as Figure 1The main air duct 4 shown in the figure is a main pipe connected in parallel. The exhaust pipe 7 is connected in parallel through the exhaust main pipe 8. After the connection, the airflow of the main air duct 4 is split, so that the processing capacity of each shakron 5 is greatly reduced compared with the processing capacity of a single shakron 5 traditionally configured in the dust collector. If the number of shakrons 5 is defined as n, the processing capacity of each shakron 5 is currently one nth of the shakron 5 traditionally configured in the dust collector.

[0033] Correspondingly, the bag dust collector configured at the rear stage of Shaklong 5 is equipped with an exhaust main pipe 8 for introducing gas, and the air inlet end of the exhaust main pipe 8 is used to be connected in parallel with the exhaust pipe of Shaklong 5.

[0034] In addition, the third port of the shaker 5 is located at the lower end and is often named as the gray port. Therefore, it is necessary to provide a debris removal device for the gray port so that the material separated by the shaker 5 can be discharged to a certain position. The debris removal device is usually a debris removal auger 2. The upper side of the debris removal auger 2 has a pipe interface, which is connected to the gray port by a flange connection.

[0035] The part of the ash outlet provided by the ash extractor 5 is often called an ash hopper. Therefore, in terms of components, the ash extraction auger 2 receives the ash hopper, so that the ash separated by the ash extractor 5 can be delivered to a predetermined location.

[0036] The number of Shakrons 5 is at least two. The fewer the number, the greater the processing capacity of a single Shakron 5, and a relatively larger Shakron 5 is needed. The number of Shakrons 5 should not be too many. Too many will not only take up a larger space, but also make piping very difficult. Therefore, the number of Shakrons 5 should not exceed eight.

[0037] from Figure 2 It can be seen from the illustrated structure that it is relatively easy to configure when the number of shakers 5 is an even number. There are four shakers 5 in the figure, which are divided into two rows and two columns. The cut-in pipes 6 of the two shakers 5 in the left column are arranged adjacent to each other, while the cut-in pipes 6 of the two shakers 5 in the right column are biased outward, which is conducive to the four shakers 5 being connected to the main air duct 4.

[0038] When the arrangement is in a row-column matrix, due to the particularity of the position of the cut-in pipe 6, the above method can be used to avoid the position interference of the relevant pipelines. However, for the exhaust pipe 7, when the Shakron 5 is arranged in a regular matrix, the exhaust pipe 7 coaxial with the cylinder 12 will also present a regular matrix arrangement, so that Figure 1 In the illustrated structure, the exhaust pipes 7 in the same row are connected by a header pipe, which is located above the exhaust pipes 7 to facilitate the configuration of the header pipes. All the header pipes are then connected to the exhaust main pipe 8.

[0039] Furthermore, in order to optimize the configuration of the debris removal auger 2, a collecting hopper 3 with a larger top and a smaller bottom is provided on the lower side of the row and column matrix. The larger top and the smaller bottom is a typical configuration of the collecting hopper 3, with a wide mouth on the top to connect the gray mouths of all the shakers 5, and a narrowed mouth on the bottom to be flange-connected to the inlet of the debris removal auger 2.

[0040] The collecting hopper 3 is generally a cone or a quadrangular pyramid structure, and accordingly, for example, a cone, the bottom is at the top.

[0041] The shaker 5 is a shaker 5 with a diffusion box 10 at the lower end, which has a better effect of separating fine components.

[0042] The following table shows the basic parameters of the preferred Shaklon 5. For the reference numbers in the parameters, please refer to Figure 3 and Figure 4 .

[0043]

[0044] The parameters in the above table are the optimal parameters when equipped with four Shaklon 5. These parameters can be adjusted, but the adjustment amount should not be too large. For example, the lower cone angle B of the diffusion box 10 is 50°~60°, the height h3 of the diffusion box 10 is 1200~1280mm, and the large bottom diameter of the lower cone of the diffusion box 10, that is, its maximum diameter dmax is 1550~1650mm.

[0045] Since some parameters are correlated to a certain extent, the above table can also be referred to. For example, the inlet diameter of the diffusion box 10 is 1.2 times the outlet diameter, that is, the diffusion box inlet D1 and the diffusion box outlet a1 in the table.

[0046] In addition, the cylinder height of Shaklon is smaller than the cone height. Referring to the outer cylinder height h1 in the table, that is, the height of the cylinder 12, and the cone barrel height h2, that is, the height of the cone, it can be seen from the figure that the outer cylinder height h1 is smaller than the cone barrel height h2.

[0047] As an option, the barrel height of the Shaklon is 0.73 to 0.75 times the cone height.

[0048] The height of the cylinder 12 is more closely related to the diameter of the cylinder. In a preferred embodiment, the height of the cylinder is 1.34 times the diameter of the cylinder.
