Description

Technical Field

[0001] The invention belongs to the field of machining, and in particular relates to a cutting fluid treatment device. Background Art

[0002] In the field of mechanical processing, cutting fluid plays a vital role in cooling and lubricating cutting tools, thereby improving machining accuracy and extending tool life. However, the effective treatment and recycling of cutting fluid is also an important link that cannot be ignored in the machining process. Among them, the filtration of cutting fluid is a key link to ensure the quality and reusability of cutting fluid.

[0003] Generally, various types of filtration equipment are used in the process of cutting fluid filtration. These traditional filtration devices generally operate based on the principle that the liquid flows through the filter in a specific direction. During the filtration process, when the cutting fluid passes through the filter, the solid particles and impurities in it are intercepted by the filter.

[0004] However, after a period of continuous operation, a significant problem gradually emerged. As the liquid continued to flow in one direction, solid particles gradually accumulated on the filter. Over time, the filter became more and more blocked. Once the filter was blocked, the filtration efficiency of the equipment dropped sharply and eventually it could not maintain normal filtration function. At this point, the only way to restore the filtration function was to shut down the machine. Maintenance personnel then needed to manually remove the accumulated debris and impurities in the filter. This process was not only time-consuming but also labor-intensive.

[0005] Frequent clogging of the filter results in a shorter effective filtration time for traditional filtration equipment. This not only interferes with the continuity of the machining process, but also increases the overall production cost. The interruption of the production line caused by the need to clean the filter reduces production efficiency, while the additional manpower and time invested in maintenance further increase production costs. In addition, improper handling of filtered impurities may also cause environmental pollution problems. Therefore, the industry urgently needs to develop a new cutting fluid filtration device or method to effectively solve the problem of filter clogging and improve the efficiency and stability of cutting fluid filtration. Summary of the invention

[0006] In view of this, the present invention aims to provide a cutting fluid treatment device to solve the problem that the directional flow of liquid causes filter screen clogging and reduces the effective filtration time.

[0007] To achieve the above object, the present invention adopts the following technical solution: a cutting fluid treatment device, comprising: A casing having an inlet end and an outlet end; A filter assembly is provided at the inlet end for filtering the cutting fluid entering the inlet end and leaving the cutting slag inside; The flow disturbance acceleration component is arranged in the casing and is used for disturbing the fluid inside the filter component and accelerating the cutting fluid to flow out from the outlet end.

[0008] Furthermore, the filter assembly is a cylinder with an opening on one side close to the inlet end, a backflow portion protruding from the bottom wall surface is formed on the bottom wall, and filter holes are provided on the wall surface of the cylinder and the wall surface of the backflow portion.

[0009] Furthermore, the cylinder is a hollow truncated cone with an opening side area larger than a bottom wall area, and the reverse flow portion is a hollow truncated cone with a side facing the inlet end smaller in area than a side close to the bottom wall.

[0010] Furthermore, a flow diversion portion is provided on one side of the filter assembly close to the inlet end.

[0011] Furthermore, the turbulence acceleration component includes a rotating shaft rotatably connected to the casing, a first impeller and a second impeller connected to the rotating shaft, the first impeller is used to push the fluid into the filter component through the reverse flow filter hole, and the second impeller is used to push the fluid in the casing to move toward the outlet end.

[0012] Furthermore, the first impeller is a plurality of blades evenly distributed along the circumference of the peripheral wall of the rotating shaft, and is used to push the fluid to move radially along the rotating shaft.

[0013] Furthermore, a fluid acceleration chamber is coaxially sleeved outside the rotating shaft, and the second impeller is arranged in the fluid acceleration chamber.

[0014] Furthermore, the fluid acceleration chamber is a hollow cylinder with openings on both sides for fluid to enter and exit.

[0015] Furthermore, the casing includes a shell and a cover, the cover is rotatably connected to the inlet end of the shell, and a flange pipe for connecting a pipeline is provided on the cover.

[0016] Furthermore, the shell and the cover are locked by a locking part.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. The device is equipped with a flow disturbance acceleration component to disturb the fluid in the filter component, avoid the continuous action of the unidirectional flow of the fluid, and delay the clogging time of the filter component while ensuring the smooth passage of the fluid through the filter component, thereby ensuring long-term effective filtration; 2. This device is provided with a turbulence acceleration component, which forms a turbulence in the filter component and accelerates the fluid near the outlet end, thereby helping the liquid to flow out more quickly, so that the total fluid flow rate will not be reduced by the turbulence, thereby extending the effective filtration time while ensuring the overall flow rate of the fluid.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely explain the technical solutions in the embodiments of the present invention. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict, and the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0021] It should be noted that the descriptions of the present invention regarding directions such as "left", "right", "left side", "right side", "upper", "lower", "top", "bottom", etc. are all defined based on the relationship between the orientations or positions shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the structure described must be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention. In the description of the present invention, the meaning of "multiple" is more than two, unless otherwise clearly and specifically defined.

[0022] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or 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.

[0023] Referring to the accompanying drawings, this embodiment is described, a cutting fluid treatment device, comprising: The casing is provided with an inlet end 3 and an outlet end 4; the inlet end 3 and the outlet end 4 are both provided in the form of flange pipes, and the flange pipe and the casing can be connected in an integral molding or welding manner, and a reasonable selection can be made according to the actual processing means. The inner wall of the casing adopts a streamlined shape as a whole, in order to reduce the resistance of the fluid. In order to cooperate with the movement of the fluid, the casing is overall set in the shape of a rotating body, extending from the inlet end 3 to the outlet end 4, and the radius is set in a gradually decreasing manner, which helps to increase the fluid flow rate.

[0024] The filter assembly 6 is arranged at the inlet end 3 to filter the cutting fluid entering the inlet end 3 and leave the cutting residue inside; the filter assembly 6 is arranged at a position where the fluid enters from the inlet end 3 and is directly filtered through the filter assembly 6, leaving the residue inside the filter assembly 6, and the fluid, that is, the cutting fluid, flows along the filter holes, thereby completing the filtering of the fluid.

[0025] The turbulence acceleration component is arranged in the housing, and is used to turbulent the fluid inside the filter component 6 and accelerate the cutting fluid to flow out from the outlet end 4. The turbulence acceleration component is mainly arranged to avoid that when the fluid flows through the filter component 6, there is only a single flow direction. After the turbulence state is formed, the filter residue can form a non-directional movement in the filter component 6, so that the residue can be prevented from forming a scale blockage effect under the action of the unidirectional fluid, directly blocking the filter screen, and extending the effective filtration time. At the same time, the turbulence acceleration component can also increase the fluid flow rate, thereby compensating for the flow rate reduced by the turbulence effect, thereby ensuring that the overall speed of the fluid is not affected as a whole.

[0026] In this embodiment, the filter assembly 6 is a cylinder with an opening on one side near the inlet end 3, and a backflow portion 8 protruding from the bottom wall surface is formed on the bottom wall, and filter holes are provided on the wall surface of the cylinder and the wall surface of the backflow portion 8. The opening side of the cylinder faces the inlet end 3, which is convenient for filtering. After the fluid enters, the backflow surface can be formed for the backflow of the liquid through the setting of the filtering backflow portion 8, so that the liquid can merge with the fluid that continues to enter from the inlet end 3 after the backflow, and avoid forming a single flow direction of the fluid in the filter assembly 6, thereby reducing the occurrence of blockage.

[0027] In this embodiment, a diverter portion 7 is provided on the side of the filter assembly 6 close to the inlet end 3. The provision of the diverter portion 7 can divert the fluid. On the one hand, it can prevent excessive pressure after the fluid enters from directly acting on the bottom wall of the filter assembly 6 to form a unidirectional flow field. On the other hand, it can be used as a handle to form a better gripping position when disassembling and assembling the filter assembly 6. The diverter portion 7 is specifically provided on the top wall of the reverse flow portion 8, and the connection form can be reasonably selected according to actual conditions. The diverter portion 7 is specifically a connecting rod, and a circular arc diverter surface is provided on the end of the connecting rod close to the inlet end 3.

[0028] In this embodiment, the turbulence acceleration component includes a rotating shaft 9 rotatably connected to the housing, a first impeller 10 and a second impeller 11 connected to the rotating shaft 9, the first impeller 10 is used to push the fluid into the filter assembly 6 through the filter hole of the reverse flow portion 8, and the second impeller 11 is used to push the fluid in the housing to move toward the outlet end 4. The first impeller 10 is a plurality of blades evenly distributed along the circumference of the peripheral wall of the rotating shaft 9, and is used to push the fluid to move radially along the rotating shaft 9. The first impeller 10 is specifically in the shape of a straight plate, and the inclination angle at the edge is the same as that of the diversion portion 7, and the inclination angle may not be set, but the blade itself should be set with a pressure angle that is conducive to the radial movement of the liquid along the rotating shaft 9, and a reasonable setting can be made according to actual conditions. Through the arrangement of the first impeller 10, the fluid can be reversed back into the filter assembly 6 through the filter holes of the reverse flow portion 8, thereby preventing the filter residue from clogging the filter holes under the action of a single fluid. At the same time, thanks to the fact that the cylinder is a hollow truncated cone with an opening side area larger than the bottom wall area, the reverse flow portion 8 is a hollow truncated cone with an area smaller than the bottom wall side toward the inlet end 3, that is, the filtering pressure surfaces are all arranged inclined, and with the action of the turbulent fluid, the complete clogging of the filter holes can be prevented, thereby allowing the filter assembly 6 to operate in an effective filtering state for a long time.

[0029] In this embodiment, the rotating shaft 9 is coaxially sleeved with a fluid acceleration chamber 12, and the second impeller 11 is arranged in the fluid acceleration chamber 12. The fluid acceleration chamber 12 is a hollow cylinder, and openings are arranged on both sides for fluid inlet and outlet. Specifically, the fluid acceleration chamber 12 is arranged as a straight tube pipeline with both ends open, which is fixed to the inner wall of the housing 1 by bolts or other connection methods. When the second impeller 11 rotates, a directional flow pressure can be formed from the inlet end to the outlet end of the fluid acceleration chamber 12. Due to the setting of the fluid acceleration chamber 12 and the high-speed ejection of the directional flow pressure from the fluid acceleration chamber 12, a high-pressure fluid will be formed at the outlet of the fluid acceleration chamber 12, thereby forming an ejection flow effect on the fluid outside the fluid acceleration chamber 12. The fluid on the peripheral side is further accelerated, so that in the entire area of ​​the fluid acceleration chamber 12, the fluid is in a state of accelerated flow, so that the fluid in the filter assembly 6 forms a traction effect, so that the fluid in the filter assembly 6 after the turbulence quickly moves downward again, so that the overall liquid flow rate is increased by about 15%-18% compared with when the fluid acceleration chamber 12 is not arranged.

[0030] In this embodiment, the housing comprises a shell 1 and a cover 2, wherein the cover 2 is rotatably connected to the inlet end of the shell 1, and a flange pipe for connecting a pipeline is provided on the cover 2. The cover 2 is rotatably connected to the shell 1 through a pin shaft.

[0031] In this embodiment, the shell 1 and the cover 2 are locked by the locking part 5. The filter assembly 6 is installed in the shell 1 in a specific snap-fit ​​manner. Specifically, a downward protrusion can be set at the edge of the filter assembly 6, and a slot that matches the protrusion can be set on the end face of the shell 1. When the protrusion and the slot are matched, a sealing ring is matched to achieve the sealing of the connection. At the same time, a sealing ring is also set at the contact point between the shell 1 and the cover 2 to ensure the sealing when the cover 2 and the shell 1 are connected to prevent the fluid from flowing out. The locking part 5 can be specifically set as a bolt group. When the shell 1 and the cover 2 are tightly matched, mutually matching openings are set at the corresponding positions of the two, and the bolt group is inserted into the opening to complete the locking of the shell 1 and the cover 2.

[0032] When in use, open the cover 2 and install the filter assembly 6 in the housing 1, then cover the cover 2 and lock it through the locking part 5, and connect the inlet end 3 and the outlet end 4 of the housing to the corresponding pipelines to ensure the sealing. One end of the rotating shaft 9 is connected to a driving device, such as a motor-driven reducer, and the output end of the reducer is connected to the rotating shaft 9. The specific driving structure can be reasonably selected according to the actual fluid flow rate and pressure. The operating driving device drives the rotating shaft 9 to rotate.

[0033] After the cutting fluid enters from the inlet end 3 with the residue, it flows around under the diversion effect of the diversion part 7, and the fluid enters the shell 1 after being filtered by the filter component 6, and is quickly filled, so that the fluid is in the entire shell 1. At this time, the rotation of the shaft 9 drives the first impeller 10 and the second impeller 11 to rotate synchronously. The first impeller 10 will push laterally, so that the fluid cuts into the filter component 6 from the filter hole of the counterflow part 8 and acts with the subsequent fluid entering from the inlet end 3, forming a certain turbulence effect. After the two flow back, part of the fluid is discharged from the filter hole, and the other part is inclined along the filter component 6 to avoid continuous downward flow, continuously discharged along the filter hole and finally acts on the bottom wall of the filter component 6, and convects with the fluid cut into by the counterflow part 8 close to the bottom wall, and finally flows downward from the filter hole of the bottom wall. This process can effectively activate the residue stuck in individual filter holes to prevent blockage.

[0034] When the second impeller 11 rotates, downward fluid pressure can be formed, which is quickly discharged from the fluid acceleration chamber 12 to form an ejected fluid, helping the fluid in the entire cavity of the shell 1 to flow downward quickly and be discharged from the outlet end 4, thereby increasing the fluid flow rate and improving the overall filtration efficiency.

[0035] The flow turbulence acceleration component can also be replaced as a whole with a high-pressure air pipe, specifically, the high-pressure air pipe sprays the reverse flow part 8 and the high-pressure air pipe sprays downward from the fluid acceleration chamber 12, and the form of the pipeline and the air supply form can be reasonably set according to actual conditions. The above-mentioned flow turbulence and fluid acceleration functions can also be achieved.

[0036] In the above description, the sensors, controllers and control programs that may be involved are all existing technologies and will not be described in detail.

[0037] The embodiments of the present invention disclosed above are only used to help illustrate the present invention. The embodiments do not describe all the details in detail, nor do they limit the invention to the specific implementation methods described. According to the content of this specification, many modifications and changes can be made. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can understand and use the present invention well.
