Description

Technical Field

[0001] This utility model relates to the field of wool filtration technology, specifically to a wool coarse filtration device. Background Technology

[0002] During the production of sheepskin, the sheepskin is ironed. During the ironing process, some wool will fall off the sheepskin. Since wool is very light, if it is not collected, it will float inside the workshop. The wool floating inside the workshop can be inhaled by the workers, which will affect their health. Therefore, it is necessary to collect the wool.

[0003] Currently, wool collection typically involves connecting a wool extraction device to an ironing machine. This device includes a conveying pipe, one end of which is connected to a filter. The filter filters the wool, thus collecting it. However, when using this method to collect shed wool, the filter cartridge needs to be disassembled for cleaning or replacement after about a week of use. Because the filter cartridge is relatively large, cleaning or replacing it is very cumbersome, and the high frequency of cleaning or replacement increases the workload of the staff. Summary of the Invention

[0004] In view of this, the present invention provides a wool coarse filtration device to solve the problem of frequently disassembling the filter element in the filtration device for cleaning or replacement, which increases the burden on the staff.

[0005] To solve the above-mentioned technical problems, the wool coarse filtration device provided by this utility model adopts the following technical solution:

[0006] A wool coarse filtration device includes a filter box with an air inlet and an air outlet, capable of performing three-stage filtration of wool. The filter box contains a separating filter assembly for dividing its internal space into a first filtration space and a second filtration space. The air inlet communicates with the first filtration space, and the air outlet communicates with the second filtration space. The first filtration space contains a first filter assembly for initial filtration of the wool entering the first filtration space. The separating filter assembly performs secondary filtration of the wool. The second filtration space contains a second filter assembly for tertiary filtration of the wool. The separating filter assembly includes a partition plate longitudinally fixed within the filter box. A plurality of filter holes are formed on the side of the partition plate from top to bottom, with filter units for filtering the wool respectively on each of the filter holes. The filter units are located within the second filtration space.

[0007] Furthermore, the first filter assembly includes a first filter frame inclinedly disposed on the partition plate, the filter frame having a first filter screen for filtering wool, and a downwardly inclined baffle plate fixedly connected to the upward-facing end of the filter frame.

[0008] Furthermore, the second filter assembly includes a second filter frame that is inclined from top to bottom, with one end of the second filter frame fixedly connected to the inner top of the filter box and the other end forming an airflow channel with the inner bottom of the filter box. The second filter frame is provided with a second filter screen for filtering wool.

[0009] Furthermore, the filtration unit is a filter bag.

[0010] Furthermore, the air inlet is located in the lower part of the first filtration space, and the air outlet is located in the upper part of the second filtration space.

[0011] Furthermore, the side of the filter box is provided with a feeding door for taking out wool from the first filter space and the second filter space.

[0012] Furthermore, the top of the filter box is sealed with a removable sealing cover to facilitate cleaning of the first filter assembly, the second filter assembly, and the separator filter assembly inside the filter box.

[0013] Furthermore, the air outlet is provided with an air outlet pipe for discharging the filtered gas.

[0014] The above-mentioned technical solution of this utility model has at least the following beneficial effects: 1. By setting up a first filter component, a second filter component, and a partition filter component, three-stage filtration of wool entering the filter box can be achieved. After the filter box performs three-stage filtration of wool, most of the wool can be effectively filtered out. At this time, a small amount of wool carried in the air enters the existing filter device for filtration, which can extend the service life of the filter element in the filter device. At the same time, it can also reduce the cycle of cleaning or replacing the filter element by the staff, thus reducing the burden on the staff.

[0015] 2. The sealing cover facilitates the maintenance of the first filter assembly, the second filter assembly, and the partition filter assembly. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0019] After the wool is extracted by the wool extraction device, it enters the air carrying the wool through the conveying pipe 16 and blows it into the coarse filter through the air inlet 2. Then it undergoes three stages of filtration through the first filter component, the second filter component and the separation filter component. Finally, it is discharged from the air outlet 3 and the air outlet pipe 15 into the existing filter for further filtration.

[0020] After introducing the basic principles of this utility model, various non-limiting embodiments of this utility model are described in detail below. Any quantity of elements in the accompanying drawings is for illustrative purposes only and not for limitation, and any naming is for distinction only and has no limiting meaning.

[0021] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0022] An embodiment of the wool coarse filtration device provided by this utility model: like Figure 2As shown: The wool coarse filtration device includes a filter box 1 with an air inlet 2 and an air outlet 3, which can perform three-stage filtration of wool. The filter box 1 is provided with a partition filter component for dividing the internal space of the filter box 1 into a first filtration space 4 and a second filtration space 5. The partition filter component is used for secondary filtration of wool. The air inlet 2 is connected to the first filtration space 4, and the air outlet 3 is connected to the second filtration space 5. The air inlet 2 is located in the lower part of the first filtration space 4, and the air outlet 3 is located in the upper part of the second filtration space 5.

[0023] The first filtration space 4 is provided with a first filtration component for initial filtration of wool entering the first filtration space 4, and the second filtration space 5 is provided with a second filtration component for tertiary filtration of wool.

[0024] Furthermore, then refer to Figure 2 As shown, the separation filter assembly includes a partition plate 6 that is longitudinally fixed inside the filter box 1. Several filter holes 7 are provided on the side of the partition plate 6 from top to bottom, and filter units for filtering wool are provided on the several filter holes 7 respectively. The filter units are located in the second filter space 5. The filter unit is a filter bag 8, which is a small spherical filter bag 8.

[0025] Divide the area of ​​the side of partition 6 into five equal parts, and combine... Figure 4 As shown, the top four sections are used to create filter holes 7, and the remaining section is combined with... Figure 2 As shown, the part closest to the bottom of the filter box 1 that does not have filter holes 7.

[0026] Combination Figure 2 and Figure 3 As shown, the first filter assembly includes a first filter frame 9 inclined on the partition plate 6, a first filter screen 10 for filtering wool is provided inside the filter frame, and a downwardly inclined baffle plate 11 is fixed to the upward end of the filter frame.

[0027] After the air containing wool enters the first filter space 4, the airflow can flow upward under the action of the partition plate 6 and will not directly enter the second filter space 5. When the airflow moves upward, the wool in the air will impact the first filter screen 10. Initially, a lot of wool will pass through the first filter screen 10, but as the wool continues to impact the first filter screen 10, the wool will block the mesh of the first filter screen 10. At this time, when the wool impacts the first filter screen 10 again, the wool that was previously attached to the first filter screen 10 will form an adsorption surface on the surface of the first filter screen 10 (that is, the first filter screen 10 makes the initially smooth mesh surface rough, so it will adsorb more wool, thus forming an adsorption surface). Under the action of the adsorption surface, the wool will not easily pass through the first filter screen 10, and most of the wool will adhere to the surface of the first filter screen 10, thus achieving the first filtration of the wool.

[0028] Under the action of the baffle 11, the airflow will not flow away directly along the first filter screen 10, so that some airflow will remain in the first filter space 4 for a longer time, thus achieving better initial filtration of wool.

[0029] Next, as the airflow flows into the second filtration space 5, the separating filter component will perform secondary filtration on the wool. The air after secondary filtration carries a small amount of wool into the second filtration space 5 for a third filtration.

[0030] Next, to achieve a third filtration of the wool, the second filter assembly includes a second filter frame 12 arranged at an angle from top to bottom. One end of the second filter frame 12 is fixedly connected to the inner top of the filter box 1, and the other end forms an airflow channel with the inner bottom of the filter box 1. The second filter frame 12 is provided with a second filter screen (not shown in the figure) for filtering the wool. The filtration principle of the second filter assembly is the same as that of the first filter frame 9 and the first filter screen 10 for filtering wool.

[0031] The airflow impacts the surface of the second filter screen, which filters the wool. Some of the gas passes through the second filter screen and is discharged directly from the air outlet 3, while the other part of the gas passes through the airflow channel and is discharged from the air outlet 3, thus achieving three-stage filtration of the wool.

[0032] like Figure 1As shown, to facilitate the removal of wool filtered from the first filtration space 4 and the second filtration space 5, two access doors 13 are provided at intervals on the side of the filter box 1 for removing wool from the first filtration space 4 and the second filtration space 5, respectively. When the first filter screen 10 and the second filter screen filter wool for a long time, if a large amount of wool is filtered, some wool will fall off from the surface of the first filter screen 10 and the second filter screen. After the equipment stops operating, the fallen wool accumulates at the bottom of the first filtration space 4 and the second filtration space 5, at which point the access doors 13 can be opened for cleaning.

[0033] To facilitate the maintenance of the first filter assembly, the second filter assembly, and the partition filter assembly inside the filter box 1, the top of the filter box 1 is sealed with a removable sealing cover 14.

[0034] To facilitate connection to existing filter devices, an air outlet 3 is provided with an air outlet pipe 15 for discharging the filtered gas.

[0035] It should be noted that, attached Figure 2 The arrows marked in the text indicate the airflow direction as the gas enters the filter box 1.

[0036] Based on the above description in this specification, those skilled in the art will also understand that the following terms used, such as "upper," "lower," "front," "rear," "left," "right," "width," "horizontal," "top," "bottom," "inner," and "outer," are terms indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings of this specification. They are only for the purpose of facilitating the explanation of the present invention and simplifying the description, and do not explicitly or implicitly suggest that the device or element involved must have the specific orientation, or be constructed and operated in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms should not be understood or interpreted as limitations on the present invention.

[0037] In addition, in the description of this specification, "multiple" means at least two, such as two, three or more, etc., unless otherwise expressly and specifically defined.
