[0002] Cutting fluid is an industrial liquid used in the process of metal cutting and grinding to cool and lubricate tools and workpieces. Cutting fluid is scientifically compounded with a variety of super-functional additives. It has good cooling performance, lubrication performance, rust prevention performance, oil removal and cleaning functions, anti-corrosion function and easy dilution. Cutting fluid is an important factor in ensuring the normal operation of machine tools, machining centers and other equipment. During the process of parts processing, metal debris will be mixed into the cutting fluid. In order to recycle the cutting fluid, it is usually necessary to use a filtration system to filter out the aforementioned metal debris. During the recycling process, the cutting fluid stored in the equipment is gradually lost, so it is necessary to regularly add cutting fluid to ensure the normal operation of the equipment.

[0003] In the prior art, cutting fluid is usually mixed with stock liquid and water on site in the workshop, and the filling method is usually to use a filling bucket with facilities such as a trolley to fill the equipment with cutting fluid. However, for a machining workshop equipped with a large number of machine tools and machining centers, the aforementioned cutting fluid filling method has problems such as low filling efficiency and untimely filling. In summary, it is necessary to develop and design a cutting fluid mixing and filling system for machining workshops. Utility Model Content

[0021] In order to further understand the content, features and effects of the present invention, the following embodiments are given to explain in detail.

[0022] Embodiment 1

[0023] See also Figure 1 and Figure 2The cutting fluid mixing and filling system of the utility model includes a proportioning pump 21 and an explosion-proof filter bottle 24. The outlet of the explosion-proof filter bottle 24 is connected to the first inlet of the proportioning pump 21 through a pipeline. The inlet of the explosion-proof filter bottle 24 is connected to a water source pipeline 23. A raw liquid pipeline 28 is installed on the second inlet of the proportioning pump 21 and a flow switch 20 is installed on the raw liquid pipeline 28. An output pipeline 27 is installed on the outlet of the proportioning pump 21 and a flow meter 29 is installed on the output pipeline 27.

[0024] The proportioning pump 21 is a pump that extracts and mixes two media in proportion. The explosion-proof filter bottle 24 is used to filter the input water source, filter out the particulate impurities that are potentially contained in the water source, improve the cleanliness of the water source, and improve the quality of the cutting fluid. By installing a flow switch 20 on the stock liquid pipeline 28, the extraction flow of the stock liquid can be continuously monitored when the mixing and filling system is running. When the extraction flow measured by the flow switch 20 is significantly reduced or even zero, it means that the stock liquid has been drained. At this time, the mixing and preparation of the cutting fluid and the filling should be stopped in time to avoid damage to the mixing and filling system. By installing a flow meter 29 on the output pipeline 27, the flow of the cutting fluid after mixing and preparation is measured, and the technical effect of quantitative filling is achieved.

[0025] The water source pipeline 23 is connected to the water source 15 through the water source extraction pipe 11, the discharge port of the explosion-proof filter bottle 24 is connected to the sewage collecting barrel 14 through the discharge pipe 10, the raw liquid pipeline 28 is connected to the raw liquid barrel 12 through the raw liquid extraction pipe 6, and the supply main pipeline 7 is connected to the output pipeline 27, and the mixed and prepared cutting fluid is supplied to the outside through the supply main pipeline 7.

[0026] Among them, the stock liquid barrel 12 is obtained through external purchase, and a high-concentration cutting fluid stock liquid is stored in the barrel, and the end of the stock liquid extraction tube 6 is inserted into the bottom of the inner cavity of the stock liquid barrel 12. The water source 15 is a water supply network, and a pressure transmitter 25 and an electric ball valve 22 are installed on the water source pipeline 23. The purpose of setting the pressure transmitter 25 is to monitor the water pressure of the water supply network. The normal operation of this mixing and filling system is based on the premise that the water supply network has a suitable water source pressure. When the water pressure in the water supply network is lower than the set value or higher than the set value, the system will not be able to operate normally. At this time, the mixing and preparation of the cutting fluid and the filling should be stopped in time. The purpose of setting the electric ball valve 22 is to control the on-off of the water source pipeline 23. As mentioned above, when the water pressure in the water supply network exceeds the set water pressure range, the electric ball valve 22 can shut off the water source pipeline 23.

[0027] A manual ball valve 26 is installed on the sewage outlet of the explosion-proof filter bottle 24. When sewage discharge needs to be opened, the manual ball valve 26 is opened. When the mixing and filling system is in operation, the manual ball valve 26 is usually in a closed state.

[0028] It also includes a controller 19, a proportioning pump 21, a flow switch 20 and a flow meter 29 connected to the controller 19, and a pressure transmitter 25 and an electric ball valve 22 connected to the controller 19. The controller 19 is constructed based on a PLC chip and is used to provide system control functions.

[0029] In this embodiment, a wall-mounted box body 1 is also included. A box door 2 with a door lock 4 is installed on the front of the wall-mounted box body 1. A vertical box partition 16 is installed inside the wall-mounted box body 1. The controller 19 is located on the left side of the box partition 16. The proportioning pump 21, the explosion-proof filter bottle 24, the water source pipeline 23, the output pipeline 27 and the raw liquid pipeline 28 are located on the right side of the box partition 16. As shown in the figure, a leakage protection switch 17 and a transformer 18 are also installed on the left side of the box partition 16. The leakage protection switch 17 can be used to control the power on / off of the mixing and filling system. The transformer 18 is used to convert the city power into a suitable power supply required by the system, and each electrical component is connected to the transformer 18.

[0030] The purpose of setting the partition 16 in the box is to isolate the leakage protection switch 17, the transformer 18 and the controller 19 from the proportioning pump 21, the explosion-proof filter bottle 24 and the related pipelines and accessories on the right side. In this way, even if the components on the right side leak during operation, no cutting fluid / water source will splash onto the leakage protection switch 17, the transformer 18 and the controller 19, thereby achieving a safe isolation effect.

[0031] In this embodiment, a water source interface 33, a sewage interface 32, a raw liquid interface 30 and an output interface 31 are installed on the bottom wall of the wall-mounted box 1. The water source interface 33 connects the water source pipeline 23 with the water source extraction pipe 11, the sewage interface 32 connects the port of the manual ball valve 26 with the sewage pipe 10, the raw liquid interface 30 connects the raw liquid pipeline 28 with the raw liquid extraction pipe 6, and the output interface 31 connects the output pipeline 27 with the supply main pipeline 7.

[0032] A display screen 3 and a control button 5 are also installed on the box door 2, and the display screen 3 and the control button 5 are connected to the controller 19. The display screen 3 is used to display the working condition information of the mixing and filling system, such as flow information, alarm information, etc., for on-site operation and maintenance personnel to consult. The control button 5 is used to control the operation of the mixing and filling system. The control button 5 may include an emergency stop button to perform an emergency stop operation when an abnormal emergency occurs in the system.

[0033] By providing a wall-mounted box 1 with a water source interface 33, a sewage interface 32, a raw liquid interface 30 and an output interface 31 and installing the main components inside the wall-mounted box 1, an integrated box-type cutting fluid mixing and filling device is formed, so that the box-type cutting fluid mixing and filling device can be conveniently arranged in a machine workshop in an integrated form, thereby improving the flexibility of application.

[0034] Figure 1 The cutting fluid mixing and filling system shown in is in a working mode. In this working mode, the mixed cutting fluid is directly supplied and filled to each cutting fluid application equipment 13 in the machining workshop through a pipeline, and the supply main line 7 is laid along the layout path of the cutting fluid application equipment 13 in the machining workshop.

[0035] It also includes a plurality of supply branch lines 8 connected to the main supply line 7, and a solenoid valve 9 is installed on each supply branch line 8, each supply branch line 8 is respectively connected to a plurality of cutting fluid application devices 13, and each solenoid valve 9 is connected to a controller 19. In this application mode, a signal cable can be used to send a cutting fluid level signal generated by the cutting fluid application device 13 to the controller 19 of the present mixing and filling system. When the controller 19 receives the cutting fluid level information of the cutting fluid application device 13 and determines that the device needs to be filled with cutting fluid, the controller 19 controls the solenoid valve 9 on the corresponding supply branch line 8 to open, and starts the proportioning pump 21 at the same time, and the proportioned cutting fluid is injected into the cutting fluid storage tank of the cutting fluid application device 13 through the main supply line 7 and the supply branch line 8, until the cutting fluid storage tank is filled to a suitable liquid level, the controller 19 controls the solenoid valve 9 on the supply branch line 8 to close and the proportioning pump 21 to stop running.

[0036] Embodiment 2

[0037] Figure 2 and Figure 3 Another working mode of the cutting fluid mixing and filling system is given in the figure. Different from the working mode in Example 1, in this working mode, the mixing and filling system fills the mixed cutting fluid into a ton barrel 34 for storage. After that, the cutting fluid can be taken from the ton barrel 34 and transferred to the cutting fluid application equipment 13 by using tools such as a filling vehicle / filling barrel.

[0038] In this embodiment, a ton barrel 34 is also included. The supply main line 7 is connected to the ton barrel 34 and a solenoid valve 9 is installed on the supply main line 7. A high and low liquid level sensor 35 is installed on the ton barrel 34. The high and low liquid level sensor 35 is connected to the controller 19.

[0039] The high and low liquid level sensors 35 are used to detect the liquid level height of the cutting fluid in the ton barrel 34, so as to determine whether it is necessary to mix and prepare the cutting fluid and replenish it in the ton barrel 34. When the cutting fluid level in the ton barrel 34 is lower than the liquid level sensor at the low position, the controller 19 controls the solenoid valve 9 on the supply main line 7 to open and the proportioning pump 21 to start operation. After the cutting fluid is mixed and prepared, it is added to the ton barrel 34 through the supply main line 7, and the internal liquid level gradually increases. When the cutting fluid level in the ton barrel 34 is higher than the liquid level sensor at the high position, the controller 19 controls the solenoid valve 9 on the supply main line 7 to close and the proportioning pump 21 to stop operation.

[0040] A discharge pipe with a valve is provided at the bottom of the side wall of the ton barrel 34. When a filling vehicle / filling barrel or other tool is needed to take the cutting fluid, the valve on the discharge pipe is opened and then closed after the cutting fluid is taken.
