Description

Technical Field

[0001] This utility model relates to the field of mechanical processing technology, specifically to an emulsion collection and leakage monitoring device. Background Technology

[0002] Machine tool emulsions or cutting fluids are widely used in various machining processes such as turning, milling, and grinding. With the explosive advancement of machine tool equipment, especially the upgrading of cutting tools, and the need for high-strength, high-efficiency, and high-standard equipment and parts for cooling, lubrication, and rust prevention, more than 95% of metalworking machine tools use emulsions or cutting fluids during operation to achieve the functions of lubrication, cooling, and rust prevention.

[0003] Traditional emulsion collection devices involve installing a collection box under the tray of the machine tool. When the machine tool processes the parts, the emulsion flows into the collection box, is collected, and then the emulsion inside the collection box is transported to a storage tank through pipelines. However, when the emulsion inside the collection tank is transported to the storage tank, it is connected by two pipes. Over time, the seal between the two pipes will decrease, causing the emulsion to leak out through the gaps in the pipe connection. The leaked emulsion can easily seep into the soil, causing soil pollution. If the emulsion is directly discharged into water bodies, it will also cause serious water pollution, thereby reducing the effectiveness of the collection tank. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Over time, the seal at the connection point between the two pipes will decrease, causing the emulsion to leak out through the gaps in the pipe connection, thereby reducing the effectiveness of the collection box.

[0016] In view of this, the present invention provides an emulsion collection leakage monitoring device. Through the cooperation of a horizontal plate, support column, tray, float, upright, switch and alarm, leakage monitoring is achieved during emulsion collection. This solves the problem that when two pipes are connected for a long time, the sealing of the connection point between the two pipes will decrease, causing the emulsion to leak out through the pipe connection gap, thereby reducing the effectiveness of the collection box.

[0017] Those skilled in the art will connect the electrical components and their compatible power supplies in this case using wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle below, where the electrical components are connected in the order of operation. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without further explanation of electrical control.

[0018] Example 1, by Figure 1-5 As can be seen, the emulsion collection and leakage monitoring device in this case includes a collection box 1, a guide hopper 2 fixedly connected to the top of the collection box 1, a filter screen 4 installed inside the upper part of the collection box 1, an outlet pipe 11 connected to the lower side wall of the collection box 1, and a connecting pipe 12 fixedly connected to the end of the outlet pipe 11 by bolts. A monitoring component is installed outside the collection box 1; the monitoring component includes a horizontal plate 13, a support column 14, a tray 15, a float 16, a vertical pole 17, a switch 18, and an alarm 8; the horizontal plate 13 A support column 14 is fixed to the bottom of the horizontal plate 13 near the liquid outlet pipe 11 on the side wall of the collection box 1. A tray 15 is fixed to the bottom of the side wall of the support column 14 by bolts. A float ball 16 is installed inside the tray 15. A vertical rod 17 is fixed to the top of the float ball 16. The vertical rod 17 passes through the tray 15 and is movably connected to the tray 15. A switch 18 is fixed to the bottom of the horizontal plate 13 by bolts. An alarm 8 is fixed to the other side of the outer wall of the collection box 1 away from the horizontal plate 13 by bolts. In the specific implementation process, it is worth noting that the collection box 1 is designed with an open top and a closed bottom to facilitate the collection of emulsion. It is made of 304 stainless steel. The guide bucket 2 adopts a funnel-shaped structure to expand the receiving area, allowing the emulsion generated during machine tool processing to flow more smoothly and centrally into the collection box 1, reducing splashing and loss of emulsion. It is also made of 304 stainless steel. The float 16 is made of polypropylene (PP) foam material. Polypropylene itself has a lower density than water, and after foaming, the density is further reduced, allowing it to float more easily in the emulsion. At the same time, polypropylene has good chemical stability. It can withstand the corrosion of various chemicals in the emulsion (such as surfactants, rust inhibitors, etc.), and is not prone to aging, deformation or dissolution even after long-term immersion in the emulsion. The pole 17 is made of polystyrene, and the switch 18 can be an OMRON D4N-4120. The filter screen 4 is made of 304 stainless steel wire mesh. The outer wall of the outlet pipe 11 is connected to a delivery pump through a flange, bolts and sealing ring. The model of the delivery pump is selected according to the actual situation to meet the working adjustment. The end of the connecting pipe 12 is connected to the external storage pipe. The alarm 8 is an SG-27 and is electrically connected to the switch 18. When collecting emulsion, the staff installs the collection box 1 under the tray of the machine tool. When the machine tool is working, the emulsion on the machine tool flows through the guide bucket 2 into the filter screen 4 inside the collection box 1 to filter the emulsion. The filtered emulsion flows to the bottom of the collection box 1 for collection. When a certain volume is collected, the staff starts the delivery pump, which delivers the emulsion inside the collection box 1 to the outlet pipe 11, and then through the connecting pipe 12 into the storage pipe for storage, thus realizing the collection and storage of emulsion. Before using the collection box 1, the staff connects the tray 15 to the support column 14 with bolts. If there is a gap at the connection between the outlet pipe 11 and the connecting pipe 12, the emulsion will drip into the tray 15 through the gap. As the emulsion level in the tray 15 rises, the float 16 floats upward under the action of buoyancy. The float 16 drives the upright 17 to move. When the upright 17 rises to a certain height, it will touch the switch 18, causing the switch 18 to close. After the switch 18 closes, the circuit is connected, triggering the alarm 8. The alarm 8 will sound an audible and visual alarm to remind the staff that there is a leak at the connection between the outlet pipe 11 and the connecting pipe 12, and that it needs to be repaired in time. The staff can manually turn off the alarm 8. After the repair is completed, the staff can turn the bolts to disassemble and clean the tray 15, thus realizing leakage monitoring during emulsion collection. Furthermore, a guide assembly is provided inside the tray 15; the guide assembly includes a sleeve 19, a recess 20, and a ball 21; the sleeve 19 is fixed to the inner wall of the tray 15 on the side near the upright 17, the inner wall of the sleeve 19 has a recess 20, the inner wall of the recess 20 is fitted with a ball 21, and the outer wall of the ball 21 is attached to the outer wall of the upright 17. In the specific implementation process, it is worth noting that the sleeve 19 is made of brass, which has good wear resistance and self-lubricating properties, and the ball 21 is made of hard alloy (such as tungsten carbide). Tungsten carbide has high hardness and extremely strong wear resistance, and can be used for a long time without being easily worn. During the movement of the upright 17, the ball 21 inside the sleeve 19 rolls into contact with the outer wall of the upright 17, converting sliding friction into rolling friction, reducing the resistance to the movement of the upright 17, and enabling the upright 17 to move sensitively with the float 16. Furthermore, a pulley 9 is fixed to the bottom of the collection box 1, and a handle 10 is fixed to the front of the collection box 1. In the specific implementation process, it is worth noting that when installing the collection box 1, the staff pushes the handle 10, which moves the collection box 1 and causes the pulley 9 to move into the slideway pre-cut in the machine tool, thus facilitating the installation of the collection box 1.

[0019] Example 2, by Figure 1 and 2 It can be seen that the outer wall of the filter screen 4 is fixedly connected to the frame 3, the outer wall of the frame 3 is inserted into the upper part of the inner wall of the collection box 1, and the bottom of the frame 3 is attached to the support platform 5, which is fixedly connected to the inner wall of the collection box 1. In the specific implementation process, it is worth noting that the filter screen 4 can be connected to the frame 3 by bolts. When installing the filter screen 4, the staff moves the frame 3, and the frame 3 moves the filter screen 4, thereby inserting the frame 3 into the inside of the collection box 1 and making the bottom of the frame 3 contact the support platform 5, thus installing the filter screen 4. The staff can clean the filter screen 4 regularly. When cleaning, the staff lifts the frame 3 and removes the frame 3 from the collection box 1, thereby cleaning the filter screen 4 and realizing the assembly of the filter screen 4. Furthermore, a rubber ring 7 is attached to the outer wall of the frame 3, and the rubber ring 7 is fixed to the inner wall of the collection box 1 on the side near the guide bucket 2. In the specific implementation process, it is worth noting that the rubber ring 7 is made of oil-resistant rubber (such as nitrile rubber). The rubber ring 7 can increase the friction between the frame 3 and the collection box 1 and improve the stability of the filter screen 4. Furthermore, a water level sensor 6 is bolted to the bottom of the support platform 5. In the specific implementation process, it is worth noting that the water level sensor 6 is a non-contact ultrasonic water level sensor, model LX-100. The water level sensor 6 and the external controller use shielded twisted pair cable (model: RVVP2×0.5mm²) as the signal transmission medium. If it is necessary to accurately monitor the real-time liquid level change of the emulsion in the collection tank 1, the 4-20mA analog output terminal of the sensor should be connected to the analog input module of the PLC (such as SM1231) through the shielded twisted pair cable. When wiring, it is necessary to ensure that the positive and negative polarities are consistent, and the shielding layer should be grounded at one end to ensure the accuracy of the liquid level signal transmission (error controlled within ±1mm). The water level sensor 6 is used to monitor the liquid level of the emulsion in the collection tank 1. When the liquid level reaches the preset height, the water level sensor 6 can send a signal to the controller, which then controls the delivery pump to work and store the emulsion, thereby ensuring that the liquid level of the emulsion in the collection tank 1 is within a reasonable range and preventing overflow.
