Description

Technical Field

[0001] The utility model relates to the technical field of metal fiber processing, in particular to a cutting metal fiber cleaning device. Background Art

[0002] Metal fiber, as an emerging fiber material, is attracting attention from various industries. However, cutting fluids and lubricants are used in the manufacturing process. These fluids can adhere to the metal fiber after processing, affecting subsequent processing quality and product life. Furthermore, during the cutting process, fiber fragments and dirt adhering to the metal fiber surface must be removed to ensure product quality.

[0003] In the existing technology, a water pipe is directly inserted into the bottom of a water bucket, and the metal fiber is placed in the water bucket. The water flow is filled into the water pipe, and the water flow rolls and flushes the fibers in the bucket to clean the broken fibers and impurities. In order to achieve better results, the fibers need to be manually stirred from time to time to increase the flushing force between the water flow and the broken fibers, and to dilute the cutting fluid and lubricant to obtain qualified cutting metal fibers.

[0056] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0057] This embodiment relates to a cutting metal fiber cleaning device. The cleaning device includes a water tank 1, at least two cleaning sections 2 disposed above the water tank 1, a water inlet pipe 3 connected to the cleaning sections 2, a circulation pipe 4 connected to the water tank 1, and a circulation pump 5 on the circulation pipe 4.

[0058] The water inlet pipe 3, water outlet pipe 6, and circulation pipe 4 are each equipped with a valve for opening and closing the pipes. The cleaning section 2 has a cavity within which the metal fiber is located. Each cleaning section 2 is equipped with a filter 8. Clean water enters one cleaning section 2 through the water inlet pipe 3. The flushing water overflows from one cleaning section 2, is filtered by the filter 8, and then enters the water storage tank 1. A circulation pump 5 pumps circulating water from the water storage tank 1 into the circulation pipe 4 and delivers it to the other cleaning section 2.

[0059] The cut metal fiber cleaning device of this embodiment is provided with at least two cleaning sections 2 on the upper portion of a water storage tank 1, and a filter section 8 is provided on each cleaning section 2. Cleaning water enters the cleaning section 2 through a water inlet pipe 3, and cleans the metal fibers in one cleaning section 2. After the water is filtered by the filter section 8, the cleaned fibers are hung on the filter section 8. After the cleaning water overflows, it can be reused to clean the metal fibers in another cleaning section 2 through the circulation pump 5 and the circulation pipe 4. This arrangement not only saves the amount of cleaning water used and reduces water consumption costs, but also enables the alternating circulation of cleaning of multiple metal fibers, improving cleaning efficiency. The cyclic cleaning effect also ensures the cleaning effect and improves the product quality of the metal fibers.

[0060] Based on the above overall introduction, an exemplary structure of the cutting metal fiber cleaning device of this embodiment is as follows: Figures 1 to 3 As shown, the water tank 1 adopts a rectangular box structure with an open upper end, and the overflow tray 9 described below also has a rectangular box structure.

[0063] In addition, a filter 7 is provided on the second circulation line 402. In this embodiment, the filter 7 is a precision filter 7 made of SUS304. By providing the filter 7 on the second circulation line 402, the wash water is filtered again by the filter 7 as it passes through the circulation line 4.

[0065] In this embodiment, an overflow tray 9 is provided below the cleaning section 2, and a leakage hole 901 is provided on the overflow tray 9, which can filter out the broken fibers and larger impurities mixed in the cleaning water again, and prevent the flushed fiber powder from falling into the circulating water and clogging the circulating pump 5 and the filter 7.

[0066] like Figures 1 to 3 As shown, two cleaning sections 2 are positioned above the water tank 1, with overflow trays 9 corresponding to each cleaning section 2. The water tank 1 is divided into a first water storage chamber 101 and a second water storage chamber 102. The first and second water storage chambers 101, 102 are respectively positioned below the two overflow trays 9. In this embodiment, two cleaning sections 2 are provided for alternating cleaning. After one cleaning section 2 completes cleaning, the other cleaning section 2 continues cleaning, allowing metal fibers in the previous cleaning section 2 to be removed and replaced.

[0067] Of course, in other embodiments, multiple cleaning parts 2 can be provided to realize cyclic cleaning one by one by opening and closing the valve, which can not only further save water but also improve the cleaning efficiency.

[0068] For ease of explanation, Figures 1 to 3 As shown, in this embodiment, one cleaning portion 2 is defined as a first cleaning portion A, and the other cleaning portion 2 is defined as a second cleaning portion B. The first cleaning portion A is located above the first water storage chamber 101 , and the second cleaning portion B is located above the second water storage chamber 102 .

[0069] like Figures 4 and 5 As shown, the water inlet pipe 3 is provided with a first water inlet pipe 301 and a second water inlet pipe 302 respectively connected to the two cleaning parts 2. Among them, the first water inlet pipe 301 is connected to the first cleaning part A, and the second water inlet pipe 302 is connected to the second cleaning part B.

[0070] The first circulation pipeline 401 is provided with a first circulation pipe 4011 communicating with the first water inlet pipe 301, and a second circulation pipe 4012 communicating with the second water inlet pipe 302. The second circulation pipeline 402 is provided with a third circulation pipe 4021 communicating with one of its water storage chambers, and a fourth circulation pipe 4022 communicating with the other water storage chamber. The water outlet pipeline 6 is provided with a first water outlet pipe 601 and a second water outlet pipe 602, respectively communicating with the two water storage chambers.

[0071] Furthermore, for ease of implementation, valves are provided on the first water inlet pipe 301, the second water inlet pipe 302, the first circulation pipe 4011, the second circulation pipe 4012, the third circulation pipe 4021, the fourth circulation pipe 4022, the first water outlet pipe 601 and the second water outlet pipe 602. Figures 3 and 4 As shown, the valve on the first water inlet pipe 301 is positioned as J1, the valve on the second water inlet pipe 302 is positioned as J2, the valve on the first circulation pipe 4011 is defined as X1, the valve on the second circulation pipe 4012 is defined as X2, the valve on the third circulation pipe 4021 is defined as X3, and the valve on the fourth circulation pipe 4022 is defined as X4. The valve on the first water outlet pipe 601 is defined as C1, and the valve on the second water outlet pipe 602 is defined as C2.

[0072] In this embodiment, the above-mentioned valves are all electric stop valves. The cutting metal fiber cleaning device is also provided with a controller electrically connected to the electric stop valve. The controller is, for example, a PLC controller. The specific structure is the same as that of the prior art and will not be repeated here.

[0073] Preferably, if Figure 6 and Figure 7 As shown, the cleaning unit 2 includes a main body 201 and a bracket 202 radially inserted into the main body 201. The filter unit 8 uses a filter screen and is mounted on the bracket 202.

[0074] The filter screen of this embodiment is a metal mesh with a mesh diameter of 0.5 to 1 mm. The filter screen and the overflow tray 9 provide a secondary filter for the fiber fragments in the wash water. The filter screen also provides a primary filter for the fiber fragments, preventing them from entering the water storage tank 1 and circulating into the next wash section 2.

[0075] Still Figures 6 and 7 As shown, the body 201 is provided with a through hole for the water inlet pipe 3 to pass through. The end of the water inlet pipe 3 inserted into the body 201 is provided with an "L"-shaped elbow 10, and the water outlet of the elbow 10 faces the side wall of the body 201. By providing the "L"-shaped elbow 10 on the water inlet pipe 3 in the cleaning section 2 and the water outlet of the elbow 10 facing the side wall of the body 201, the water rotates along the side wall and enters, forming a vortex-like cleaning method. The purpose of uniform cleaning is achieved without manual stirring, thus achieving the purpose of automatic cleaning.

[0076] As a specific implementation method, the cleaning process of the cutting metal fiber cleaning device of this embodiment is as follows:

[0077] Initial stage: All valves are closed.

[0078] Phase 1:

[0079] (1) J1 is opened, C1 is opened, water flows through J1 to flush the fibers in the first cleaning section A, overflows to the overflow tray 9, filters out broken fibers, flows to the water storage tank 1, and is discharged to the sewer through C1;

[0080] (2) After about 25 to 30 minutes, J1 continues to be opened, C1 is closed, X2 is opened, and C2 and X3 are opened. Clean water continues to flush the fibers in the first cleaning section A through J1, overflows to the overflow tray 9, filters out broken fibers, flows to the water storage tank 1, passes through X3, and is pumped into the filter 7 by the circulating pump 5. The filtered water passes through X2 to flush the fibers in the second cleaning section B, overflows to the overflow tray 9, filters out broken fibers, flows to the water storage tank 1, and passes through C2 to be discharged to the sewer.

[0081] (3) After about 60 minutes, the machine is stopped, all valves are closed, the fibers in the first cleaning section A are taken out, and the fibers to be cleaned are put in again.

[0082] Phase 2:

[0083] (1) J2 and X1 are turned on, and C1 and X4 are turned on. Clean water flows through J2 to flush the fibers in the second cleaning section B, overflows to the overflow tray 9, filters out broken fibers, flows to the water storage tank 1, passes through X4, and is pumped into the filter 7 by the circulation pump 5. The filtered water flows through X1 to flush the fibers in the first cleaning section A, overflows to the overflow tray 9, filters out broken fibers, flows to the water tank, and passes through C1 to the sewer.

[0084] (2) After about 30 minutes, stop the machine, close all valves, take out the fibers in the second cleaning section B, and put the fibers to be cleaned in.

[0085] (3) Repeat the cycle until the last bucket of fiber is cleaned.

[0086] The third stage: the last bucket of fiber cleaning, no matter J1, C1, or J2, C2 are turned on, no more filtering, the entire cleaning is completed after about 30 minutes.

[0087] As mentioned above, through the first step in the first stage, the water from the first cleaning part A is discharged into the sewer for the first time for 25 to 30 minutes, and then the cleaning water is collected in the water storage tank 1. The cleaning water with less impurities is filtered again by a circulation pump and then used to clean the fibers in the second cleaning part B to avoid secondary contamination.
