Description

Technical Field

[0001] This utility model mainly relates to the field of emulsion technology, specifically a collection device for emulsion filtration. Background Technology

[0002] In metalworking processes, emulsions are often used as coolants and lubricants to effectively reduce tool wear and improve processing efficiency. However, during the recycling process, emulsions continuously acquire various impurities, especially metal shavings such as copper slag. If these impurities are not removed in time, they will not only affect the performance of the emulsion and reduce its cooling and lubrication effects, but may also damage the processing equipment and shorten its lifespan.

[0003] Existing emulsion collection devices typically use fixed filters for filtration. When these filters become clogged, frequent shutdowns for cleaning or replacement are necessary, increasing maintenance costs, disrupting production, and reducing overall processing efficiency. Furthermore, clogged filters easily overflow from the edges, causing waste and environmental pollution. Therefore, a collection device for emulsion filtration is proposed. Utility Model Content

[0004] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing emulsion collection devices typically use fixed filter screens for filtration.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A collection device for emulsion filtration includes a collection box with symmetrical movable channels on both side walls. Mounting boxes communicating with the movable channels are located on both sides of the outer side of the collection box. A winding roller is rotatably mounted inside each mounting box, and filter cloth is wound on two of the winding rollers. At least one set of cleaning brush assemblies for cleaning the filter cloth surface is located inside each mounting box, and a liquid collection assembly for collecting overflow liquid is located inside the mounting box below the movable channels.

[0007] Preferably, the mounting box has a door on one side, and a collection trough is placed at the bottom inside the mounting box.

[0008] Preferably, a drive assembly for driving the winding roller to rotate is installed on the outside of the mounting box.

[0009] Preferably, a filter screen supporting the filter cloth is installed inside the collection box, located below the filter cloth.

[0010] Preferably, the cleaning brush assembly includes two sets of cleaning brush mechanisms, each including a long-handled cleaning brush. The long-handled cleaning brush is mounted on one side of the positioning plate by several sets of bolts, and the other side of the positioning plate is connected to a support plate inside the mounting box by several sets of elastic components.

[0011] Preferably, the liquid collection assembly includes a liquid collection tank, and the bottom of the liquid collection tank is provided with a drain pipe that communicates with the inside of the collection box.

[0012] Preferably, the winding roller is detachably connected to the interior of the mounting box.

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

[0014] By setting up winding rollers and drive components, the filter cloth is moved, so that the filtration area is continuously renewed, avoiding the problem of reduced filtration flow caused by clogging of fixed filter screens, reducing the number of downtime cleanings, and ensuring filtration continuity.

[0015] By using a collection assembly located below the movable channel inside the mounting box, the collection tank can collect the emulsion overflowing from the movable channel and guide it back into the collection box through a drain pipe, reducing emulsion waste and environmental pollution.

[0016] The present invention will be explained in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0022] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0023] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly associated with those skilled in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] Example 1: Please refer to the appendix for details. Figure 1-3 A collection device for emulsion filtration is provided. The two side walls of the collection box 1 are symmetrically provided with moving channels for the filter cloth 4 to move. The two side edges of the filter cloth 4 pass through the moving channels and are connected to the winding roller 3 in the mounting box 2. A gap of 0.5-1cm is reserved between the moving channels and the filter cloth 4 to ensure that the filter cloth 4 can move freely with the rotation of the winding roller 3 and to reduce the leakage of emulsion along the channel opening. A drain port is provided at the bottom of the collection box 1, and a one-way valve is installed inside the drain port.

[0026] The mounting box 2 has a door on one side, and a collection trough 201 is placed at the bottom inside the mounting box 2. The collection trough 201 can be removed from the mounting box 2 to clean the impurities collected inside. A drive assembly 7 for driving the winding roller 3 to rotate is installed on the outside of the mounting box 2. The drive assembly 7 can be a drive motor. The drive assembly 7 is connected to an external control system to facilitate synchronous control of the drive assembly 7 in the later stage.

[0027] Inside the collection box 1, a filter screen is installed below the filter cloth 4 to support it. The filter screen can be made of metal, such as stainless steel mesh, which has high strength and corrosion resistance and can withstand the impact of emulsion and long-term immersion. Its mesh size can be designed according to actual needs. For example, for impurities such as copper slag in metal processing, a mesh size of 80-120 mesh can be selected. It is mainly used to support the filter cloth 4. The filter cloth 4 can be made of non-woven fabric layer, which is mainly used to filter fine particulate impurities such as fine copper slag and dust.

[0028] At least one set of mounting boxes 2 is equipped with a cleaning brush assembly 5 for cleaning the surface of the filter cloth 4. The cleaning brush assembly 5 includes two sets of cleaning brush mechanisms 501. The two sets of cleaning brush mechanisms 501 can brush the filter cloth 4 multiple times, thereby improving the cleaning effect. The cleaning brush mechanism 501 includes a long-handled cleaning brush 502. The length of the long-handled cleaning brush 502 matches the width of the filter cloth 4. The long-handled cleaning brush 502 is installed on one side of the positioning plate by several sets of bolts. The installation by bolts allows the long-handled cleaning brush 502 to be replaced individually after the bristles wear down, without having to replace the entire cleaning brush mechanism 501. The other side of the positioning plate is connected to the support plate 504 set inside the mounting box 2 by several sets of elastic components 503. The elastic components 503 can be springs or elastic rubber columns. The setting of the elastic components 503 ensures that the long-handled cleaning brush 502 can always be in close contact with the surface of the filter cloth 4.

[0029] Inside the installation box 2, below the movable channel, is a liquid collection assembly 6 for collecting overflow liquid. The liquid collection assembly 6 includes a liquid collection tank, which is a long strip structure with a length matching the length of the movable channel. The bottom of the liquid collection tank is equipped with a drain pipe that is connected to the inside of the collection box 1. During the filtration process, the emulsion may overflow from the movable channel into the installation box 2. The liquid collection tank is located directly below the movable channel, which can catch the overflow liquid in time and guide it back into the collection box 1 through the drain pipe.

[0030] The specific operating procedure is as follows: Pour the emulsion to be filtered from the top of the collection tank 1 or introduce it through an external pipe. When the emulsion flows through the filter cloth 4, the non-woven fabric layer filters out fine particulate impurities such as fine copper slag. The filtered clean emulsion is temporarily stored in the collection tank 1.

[0031] When impurities accumulate to a certain level on the surface of the filter cloth 4, the external control system can be activated by observing the filtration flow rate or by triggering a preset time. This activates the drive assembly 7, which drives the winding roller 3 to rotate, causing the filter cloth 4 to move and allowing the new filtration area to enter the filtration station of the collection box 1.

[0032] During the movement, the two sets of cleaning brush mechanisms 501 inside the installation box 2 clean the surface of the filter cloth 4. The long-handled cleaning brush 502 adheres tightly to the filter surface under the elastic force of the elastic component 503, brushing away the attached impurities. The impurities fall into the collection tank 201 under the action of gravity. The box door of the installation box 2 is opened periodically, the collection tank 201 is taken out, and the impurities collected inside, including copper slag, copper powder and other metal fragments, are poured into the screening equipment such as a vibrating screen. The finer copper powder is separated by the mesh grading such as a 100-mesh screen. After subsequent processing, the copper powder is recycled. At the same time, the cleaning brush mechanism 501 cleans the surface of the filter cloth 4, thereby realizing the recycling of the filter cloth 4.

[0033] Example 2: The difference between this example and Example 1 is that: please refer to the appendix for details. Figure 1-2 The winding roller 3 is detachably connected to the inside of the mounting box 2 via bolts. Filter cloth 4 is wound around the outside of the winding roller 3, and the end of the filter cloth 4 away from the winding roller 3 is connected to another set of installed winding rollers 3. In this embodiment, the structure of the filter cloth 4 is the same as in Embodiment 1, but the filter cloth 4 is designed as a "disposable consumable," meaning that the filter cloth 4 wound on a single set of detachable winding rollers 3 is of a preset length, such as 10-20 meters, which is sufficient to meet the filtration needs for a certain period. When all the filter cloth 4 wound on the outside of the winding roller 3 is used up, the filter cloth 4 is completely released from the detachable winding roller 3 and wound onto another set of winding rollers 3. New winding rollers 3 and filter cloth 4 can be replaced, and the used filter cloth 4 wound on the other set of winding rollers 3 can be removed.

[0034] The rest is the same as in Example 1.

[0035] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
