Description

Technical Field

[0001] The utility model relates to the field of cutting fluid purification, in particular to a cutting fluid purification treatment device. Background Art

[0002] Cutting fluid is an industrial liquid used in metal cutting and grinding processes to cool and lubricate tools and workpieces. It has good cooling performance, lubrication performance, rust prevention performance, oil removal and cleaning function, anti-corrosion function, and easy dilution characteristics. In mechanical processing, cutting fluid is needed to cool the workpiece and tool. With the recycling of the cutting fluid, debris and external dust generated by the workpiece processing will accumulate inside the cutting fluid, forming impurities, which will affect the normal use of the cutting fluid. In order to recycle the cutting fluid, the cutting fluid will be purified and reused, thereby reducing the cost of the cutting fluid and reducing the impact of waste emissions on the environment. In the prior art, when filtering and purifying the cutting fluid, it is necessary to manually remove the impurities accumulated on the filter to prevent the impurities from clogging the filter, resulting in a reduction in the purification speed of the cutting fluid, affecting the use of the cutting fluid.

[0003] A Chinese patent with announcement number CN220834309U discloses a processing device, which can perform secondary filtration on cutting fluid by setting a first filter cartridge and a second filter cartridge to make the filtration effect better. The turbine can drive the turbine to rotate when the cutting fluid passes through the first filter cartridge. When the turbine rotates, it drives the rotating shaft to rotate. The cleaning block drives the cleaning brush to clean the impurities such as iron filings attached to the surface of the filter. While filtering the cutting fluid, the filter plate is cleaned at the same time, and the staff does not need to manually clean the filter plate. It can collect iron filings and reduce the amount of attachment to the filter, but the iron filings and cutting fluid will enter the collection box together and still need to be filtered. In other words, this solution only solves the cleaning of the filter, and does not consider other structures, such as the treatment of cutting fluid entering the collection box.

[0004] That is to say, the cutting fluid treatment equipment in the prior art has the problems of being inconvenient to use and having poor effect. Utility Model Content

[0005] The utility model aims to provide a cutting fluid purification treatment device to solve the problems of inconvenience in use and poor effect of the cutting fluid treatment device in the prior art.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0023] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figures 1 to 4 As shown, the cutting fluid purification treatment equipment of this embodiment includes a housing 1, one end of which is provided with a liquid inlet pipe 2, and the other end of which is provided with a liquid outlet pipe 13. A liquid storage cavity is provided in the housing 1, and the liquid outlet pipe 13 is connected to the liquid storage cavity through a connecting pipe 11; a rotating filter screen 3, which is wheel-shaped in this embodiment, is rotatably arranged in the housing 1, arranged below the liquid inlet pipe 2, and located above the liquid storage cavity; a collecting member 16, which is detachably arranged in the housing 1, arranged on one side of the rotating filter screen 3, and is used to receive iron filings on the rotating filter screen 3. By rotating the wheel-shaped rotating filter screen 3, the iron filings are rotated to the collecting member 16, and the filtrate flows down from the mesh of the rotating filter screen 3. Since the wheel-shaped filter screen has a large contact area, it can effectively ensure filtration, and at the same time, it is not easy to cause the filter screen to be blocked.

[0026] The inner wall of the rotating filter screen 3 is rotatably mounted on the outer shell 1, the outer wall of the rotating filter screen 3 is fixedly connected with the inner connecting sleeve 4, the outer connecting sleeve 7 is mounted outside the inner connecting sleeve 4, a driving belt 8 is arranged on the outer connecting sleeve 7, a support rod 5 is rotatably connected inside the inner connecting sleeve 4, a locking member 6 is arranged on one side of the support rod 5, the locking member 6 is threadedly connected to the inside of the outer shell 1, and one end of the driving belt 8 is connected to a driving wheel 9. The rotating filter screen 3 can be rotated under the action of an external force, and the driving belt 8 drives the outer connecting sleeve 7 to transmit power from the inner connecting sleeve 4 to the rotating filter screen 3. The inner and outer connecting sleeves are connected by a key connection or a pin connection. A bearing is arranged outside the support rod 5 so that the inner connecting sleeve 4 can rotate, and the position of the rotating filter screen 3 is fixed by the locking member 6 to prevent it from falling during rotation.

[0027] An electric water pump 12 is provided in the connecting pipe 11, and an impeller 10 is provided in the connecting pipe 11. The electric water pump 12 drives the liquid to move so that the impeller 10 rotates. Although the cutting fluid is recovered by gravity, it needs power to be extracted. In this embodiment, the electric water pump 12 is used to extract the liquid. In order to reduce the setting of the power mechanism, the water flow power generated by the electric water pump 12 drives the impeller 10 to rotate. A rotating rod is connected to the outside of the impeller 10, and a driving wheel 9 is connected to the outside of the rotating rod, so that the rotation of the impeller 10 drives the rotation of the driving wheel 9. Then the rotating filter 3 is driven to rotate. The size of its transmission wheel and the tension adjustment of the transmission belt are conventional technologies, which are not detailed here.

[0028] A filter screen 14 is provided above the liquid storage chamber and below the rotating filter screen 3. In order to further improve the filtering effect, an additional filter screen 14 is provided to filter finer iron filings. The filter screen structure may include a fixed screen, and a disposable filter screen may also be provided on the fixed screen. The filter screen is filtered by regularly replacing the disposable filter screen. In order to facilitate replacement, a drawer structure may be provided on the housing. The housing may also be disassembled as a whole for easy overall inspection and cleaning.

[0029] A fixing member 17 is inserted into one side of the collecting member 16, and the fixing member 17 is detachably mounted on the housing 1. The collecting member 16 is inserted into the housing 1 through the fixing member 17, and the fixing member 17 is threadedly connected to the housing 1. The collecting member 16 can be removed by removing the fixing member 17.

[0030] When the equipment needs to be used, first connect the cutting fluid pipeline with the liquid inlet pipe 2, and connect the cutting fluid nozzle with the liquid outlet pipe 13, so that the cutting fluid that needs to be filtered and purified can be discharged into the shell 1 through the liquid inlet pipe 2, and then the cutting fluid discharged into the shell 1 is initially filtered by the rotating filter 3. After the larger impurities such as debris are initially filtered out, the cutting fluid will fall onto the filter 14 and be filtered for the second time by the filter 14 to filter out the smaller impurities in the cutting fluid. Finally, the filtered cutting fluid will fall into the liquid storage chamber in the shell 1. When the staff needs to reuse the filtered cutting fluid in the liquid storage chamber, the electric water pump 12 can be turned on to allow the electric water pump 12 to extract the filtered cutting fluid in the housing 1 through the connecting pipe 11, and then the cutting fluid is discharged into the cutting fluid nozzle through the liquid outlet pipe 13, and the cutting fluid nozzle is allowed to spray the cutting fluid to cool the workpiece and tool being processed. In the process of the cutting fluid passing through the connecting pipe 11, the cutting fluid will drive the impeller 10 to rotate, so that the impeller 10 is driven by the driving wheel 9 and the driving belt 8 to rotate, and then the driving belt 8 drives the outer connecting sleeve 7 to rotate, and the outer connecting sleeve 7 drives the inner connecting sleeve 4 to rotate, so that the inner connecting sleeve 4 drives The rotating filter 3 rotates inside the outer shell 1. The rotating filter 3 will continuously pass through the collecting piece 16 when it rotates, so that the larger impurities accumulated on the rotating filter 3 are scraped off and collected by the collecting piece 16, so as to achieve the effect of automatically cleaning and collecting the impurities, and prevent excessive impurities from clogging the rotating filter 3, resulting in a reduction in the filtering speed of the cutting fluid and affecting the purification of the cutting fluid by the equipment. At the same time, by setting the rotating filter 3 and the filter 14 to filter and purify the cutting fluid twice, the service life of the filter 14 is extended, and the filter 14 only filters smaller impurities, preventing the filter 14 from being quickly blocked by larger impurities, thereby extending the service life.

[0031] The structure of the outer shell 1 may include a cover plate and two side plates. The specific design is adjusted according to its use requirements. When cleaning the collecting member 16, the cover plate is removed, and then the fixing member 17 is taken out, and the collecting member 16 can be removed and cleaned.

[0032] When it is necessary to perform maintenance and repair on the interior, the fixing member 17 is taken out, the locking member 6 is taken out, the cover plate and a side plate are disassembled, and the internal structure can be taken out for maintenance and repair, which is convenient to use.

[0033] The above is only an embodiment of the utility model, and the common sense such as the known specific structure and characteristics in the scheme is not described too much here. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model. Any figure mark in the claims should not be regarded as limiting the claims involved.
