Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of filtration, in particular to a chip removal filter device of a paper belt filter. BACKGROUND

[0002] The paper belt filter is a solid-liquid separator for continuously filtering cutting fluid through filter paper. Specifically, when the cutting fluid penetrates through the filter paper mesh, metal chips and other impurities are intercepted and adsorbed on the filter paper. The conveyor belt continuously transports the filter paper carrying impurities to the chip removal area, and finally rolls the waste chips into the collection box, while the cleaned cutting fluid is recycled.

[0003] During the operation of the paper belt filter, the filter paper and the filter paper conveyor belt adopt a concave structure to achieve liquid retention filtration. When the filter paper carrying the attached impurities moves to the highest point of the conveyor belt discharge outlet, part of the impurities slightly attached to the surface are easily detached from the paper belt due to gravity, and are not discharged with the filter paper, but fall to the bottom area of the filter equipment and accumulate. This phenomenon causes the impurities to re-mix into the liquid to be filtered, ultimately causing a decrease in filtration efficiency and incomplete chip removal, thereby prolonging the overall filtration operation time.

[0031] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0032] Example 1

[0033] A chip removal and filtration device for a paper tape filter, such as Figures 1-6 As shown, the system includes a filter box 1, a liquid level alarm, and an automatic paper feeding system. A drain pipe 101 is connected to the lower left side of the filter box 1 to discharge the filtered cutting fluid. A first filter medium 3 runs horizontally through the filter box 1 from left to right. A conveying assembly 2 is installed on the filter box 1, consisting of a motor-driven roller and a mesh conveyor belt (i.e., "mesh belt"). The mesh conveyor belt conveys the first filter medium 3 to the right. The first filter medium 3 is filter paper (i.e., "paper tape"), which is laid on the mesh conveyor belt as the main filtration layer. A liquid injection pipe 4 is fixed between the front and rear sides in the middle of the filter box 1. The bottom of the liquid injection pipe 4 has two rectangular outlets. A positioning frame 5 is rotatably connected to the liquid injection pipe 4. The first filter medium 3 is located between the conveying assembly 2 and the positioning frame 5, so that the first filter medium 3 is laid in a concave cavity. A set of inclined slide rails 6 is fixed inside the filter box 1. A first mounting block 701 is slidably connected inside the slide rails 6. A mounting frame 7 is slidably connected between 01 and 02. A set of electric push rods 8 is fixedly connected inside the filter box 1. The output end of the electric push rods 8 is fixedly connected to the adjacent first mounting block 701. A laser sensor 801 is fixedly connected inside the filter box 1 near the slide rail 6. It is used to continuously monitor the thickness of the filter cake on the paper tape. The laser sensor 801 is electrically connected to the electric push rods 8 through a controller. A filter frame 9 is installed on the mounting frame 7. An inlet and outlet are provided on the lower right side of the filter frame 9. It is used to collect the fine debris and impurities falling from the highest convex point of the upper right roller of the conveying assembly 2. A collecting plate 10 is fixedly connected to the side of the filter frame 9 near its inlet and outlet. The collecting plate 10 is close to the first filter medium 3 but does not contact it. It is used to better guide the falling fine debris and impurities into the filter frame 9. A second filter medium 11 is laid inside the filter frame 9. The second filter medium 11 is also set as filter paper. It serves as an auxiliary filter layer and is used to filter the fine debris and impurities falling from the highest convex point of the upper right roller of the conveying assembly 2.

[0034] like Figures 7-10As shown, the lower side of each rectangular outlet of the liquid injection pipe 4 is provided with a material guide frame 12, the material guide frame 12 is provided in an inverted V shape, a plurality of material guide grooves 121 are opened on the material guide frame 12 and symmetrically distributed along the length direction of the material guide frame 12, the liquid injection pipe 4 is fixedly connected with guide frames 13 symmetrically distributed in front and back of the rectangular outlet, the guide frames 13 are slidingly connected with second mounting blocks 122, the second mounting blocks 122 are fixedly connected with adjacent material guide frames 12, so that the material guide frame 12 is slidingly connected with the liquid injection pipe 4, the material guide frame 12 is provided with a boundary line 123, the boundary line is arranged between the material guide grooves 121, and the boundary line 123 deviates to the right side, and the second mounting blocks 122 are fixedly connected with springs 14 between adjacent guide frames 13.

[0035] The specific operation of the paper belt filter for chip removal and filtration is as follows: After the large-flow cutting chip liquid discharged by the machining center is coarsely filtered, the cutting chip liquid in the liquid injection pipe 4 is discharged through the rectangular outlet, and then is transported to the first filter medium 3 in the form of a concave cavity paved by the mesh belt along the material guide groove 121 of the material guide frame 12, the solid particle impurities are intercepted on the surface of the first filter medium 3 to form filter cake, and the liquid penetrates the first filter medium 3 and the mesh belt to enter the bottom of the filter box 1, and is discharged through the liquid discharge pipe 101, so that two-stage high-precision filtration is realized, and the recycling of the cutting chip liquid resource of the numerical control machining center is achieved.

[0036] With the deposition of the fine cutting on the surface of the first filter medium 3, the permeability decreases, and the liquid level gradually rises, when the liquid level reaches the set height, the liquid level alarm sends a signal to the automatic paper feeding system of the filter, so that the cutting chip is fed with the first filter medium 3 to the right, and the cutting chip with residue is discharged, at the same time, the clean first filter medium 3 is introduced, and the system returns to the high-efficiency filtration state, realizing automatic, continuous and unattended operation.

[0037] When the first filter medium 3 carrying the attached impurities moves to the highest convex point position of the upper roller on the right side of the conveying assembly 2, part of the impurities slightly attached to the surface are separated from the paper belt due to gravity, in order to prevent the impurities from falling back to the concave point of the first filter medium 3, the filter frame 9 and the material collecting plate 10 are arranged on the left side close to the highest convex point position, and the two form a structure similar to a scoop, which can receive and collect the falling impurities, so that the impurities are intercepted on the surface of the second filter medium 11, thereby ensuring the filtration efficiency and avoiding incomplete chip removal and prolonging the overall filtration operation time.

[0038] With the increase of impurities on the first filter medium 3 (i.e. the filter cake thickens), the aggregate plate 10 should also be translated upward accordingly to ensure the spacing between the filter cake on the first filter medium 3 and the aggregate plate 10, otherwise it will affect the normal transmission of the first filter medium 3. The operation of dynamically adjusting the position of the aggregate plate 10 is as follows: the laser sensor 801 emits a laser pulse and receives a reflected signal, calculates the distance through photoelectric conversion and signal processing, supports high-speed sampling (such as a maximum of 9400Hz), when the paper belt filter machine is running, the impurities form a filter cake layer on the paper belt, the laser sensor 801 continuously monitors its thickness, real-time tracks the thickness change of the filter cake, and sends an electrical signal to the controller, after the controller receives the electrical signal, it controls the electric push rod 8 to adaptively and gradually extend, thereby pushing the first mounting block 701 to slide obliquely and adaptively upward along the slide rail 6, so that the mounting frame 7 drives the aggregate plate 10 to obliquely and adaptively translate upward through the filter frame 9, so as to maintain the spacing between the filter cake and the aggregate plate 10.

[0039] As described above, the guide frame 12 guides the cutting fluid to the first filter medium 3 through the guide groove 121, which can make the cutting fluid evenly distribute, the purpose is to avoid the concentration of cutting fluid distribution affecting the filtering effect, in addition, the guide frame 12 is provided with a partition line 123, which is used to guide the cutting fluid to flow to the left side of the first filter medium 3. Figure 9 As can be seen intuitively, the partition line 123 of the guide frame 12 is more biased to the right side, so that more cutting fluid flows to the left side, the purpose of such arrangement is that the left part of the first filter medium 3 belongs to primary filtration, and the right part belongs to secondary filtration, so the left part of the first filter medium 3 undertakes the main filtering role, and the right part undertakes the auxiliary filtering role, which not only improves the filtering effect, but also comprehensively considers the different filtering capabilities of each part.

[0040] When the weight borne by the left side of the guide frame 12 is too heavy, the guide frame 12 drives the second mounting block 122 to slide downward to the left along the guide frame 13 under the action of gravity, the spring 14 is compressed, so that the partition line 123 shifts to the middle, on the contrary, the spring 14 rebounds, so that the partition line 123 resets to the right, so as to dynamically adjust the distribution amount of the cutting fluid, and avoid too much cutting fluid flowing to the left part of the first filter medium 3.

[0041] Embodiment 2

[0042] Based on embodiment 1, specifically, as shown in Figure 11 and Figure 12 The lower right side of the filter frame 9 is rotationally connected with a baffle 15, a torsional spring 16 is fixedly connected between the filter frame 9 and the baffle 15, a top position frame 17 is slidingly connected to the filter frame 9 in the up-down direction, the bottom of the top position frame 17 is in extrusion fit with the middle left side of the baffle 15, the top of the top position frame 17 is provided with an inclined surface 171, and the inclined surface 171 is in extrusion fit with the lower part of the mounting frame 7.

[0043] In order to prevent the impurities collected in the filter frame 9 from falling out through the outlet when the filter frame 9 is taken off, the outlet of the filter frame 9 is closed by the baffle 15 when taken off, and the baffle 15 is automatically opened when installed, and the specific operation is as follows:

[0044] When the filter frame 9 is installed on the mounting frame 7, the baffle 15 is in the opened state, and the torsion spring 16 is in the deformed state. When the filter frame 9 is taken off from the mounting frame 7, the filter frame 9 is first lifted upward, and since the top of the top position frame 17 is abutted by the mounting frame 7, the filter frame 9 slides upward relative to the top position frame 17, and drives the baffle 15 and the torsion spring 16 on it to move upward. At this time, the baffle 15 is further opened by the abutting action of the top position frame 17, and the torsion spring 16 is further deformed. Then, the filter frame 9 is completely lifted rightward from the mounting frame 7. At this time, the torsion spring 16 is reset, the baffle 15 is reversely reset, and it pushes the top position frame 17 to slide upward relative to the filter frame 9 to reset, so that the baffle 15 closes the outlet of the filter frame 9. During the installation of the filter frame 9, the inclined surface 171 of the top position frame 17 is pressed by the mounting frame 7 to slide downward relative to the filter frame 9. When the top position frame 17 slides downward, it pushes the baffle 15 to rotate upward and open, and then pushes the filter frame 9 downward, which drives the components on it to move downward as a whole, so that the filter frame 9 is hung on the mounting frame 7, and the installation of the filter frame 9 is realized.

[0045] The above is only the preferred embodiment of the present application, and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
