Description

Technical Field

[0001] This utility model belongs to the field of machine tools, specifically relating to an automatic liquid collection mechanism and machine tool. Background Technology

[0002] If leaked liquids in industrial cleaning equipment, automatic spraying systems, or liquid circulation devices are not recovered in a timely manner, it will not only waste resources, but may also cause slippery floors, equipment corrosion, environmental pollution, or even safety accidents.

[0003] In existing technologies, leaked liquids are usually handled by manual cleaning and setting up drip trays. However, drip trays often only serve as temporary storage and still need to be emptied manually. In addition, manual cleaning is inefficient and untimely, which can easily lead to liquid overflow. Meanwhile, independent suction pumps and other equipment have a complex overall structure, high energy consumption, and high cost, which is not conducive to widespread industrial application. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing an automatic liquid collection mechanism and machine tool that is simple in structure, achieves efficient and automatic liquid collection, and improves the stability and reliability of equipment operation.

[0005] The objective of this utility model can be achieved by addressing the following technical problem: proposing an automatic liquid collection mechanism, comprising: a housing;

[0006] A spray pump is installed on the chassis, and the output end of the spray pump is connected to a spray pipe fitting. The spray pump is used to draw liquid from the chassis and deliver it to the spray pipe fitting.

[0007] A reflux assembly, comprising a flow regulating valve and a reflux pipe, wherein one end of the reflux assembly is connected between the spray pipe fitting and the output end of the spray pump, and the other end is connected to the reflux pipe, and the reflux pipe is connected to the chassis; the flow regulating valve is used to regulate the flow rate of liquid flowing into the reflux pipe;

[0008] A siphon assembly is located outside the chassis, with one end of the siphon assembly connected to a liquid suction tray and the other end connected to the return pipe;

[0009] When the spray pump is running, flowing liquid is formed in the return pipe. A negative pressure zone is generated at the connection point between the siphon assembly and the return pipe, so that external leaked liquid is sucked in through the suction plate and transported into the chassis through the return pipe.

[0010] In the above-mentioned automatic liquid collection mechanism, the siphon assembly further includes a siphon tube and a liquid receiving box. The outer wall of the return pipe has a liquid inlet. One end of the siphon tube is connected to the liquid suction plate, and the other end is connected to the liquid inlet. The liquid suction plate is placed inside the liquid receiving box.

[0011] In the aforementioned automatic liquid collection mechanism, a filter screen is also formed inside the liquid suction tray.

[0012] In the aforementioned automatic liquid collection mechanism, the end of the reflux assembly is connected to a T-shaped port, and the two ends of the T-shaped port are used to connect the spray pipe fitting and the output end of the spray pump.

[0013] In the aforementioned automatic liquid collection mechanism, the spray pipe fitting includes a quick-connect pipe and a control valve, and the T-shaped port and the quick-connect pipe are connected by the control valve.

[0014] In the aforementioned automatic liquid collection mechanism, a liquid pipeline is also connected between the T-shaped port and the flow regulating valve.

[0015] In the aforementioned automatic liquid collection mechanism, several plugs are also installed on the casing.

[0016] In the aforementioned automatic liquid collection mechanism, the chassis is further provided with a mounting bracket, the top of the mounting bracket is provided with a connecting pipe, the top of the return pipe is connected to an inlet pipe, one end of the connecting pipe is connected to the inlet pipe, and the other end is connected to the flow regulating valve.

[0017] In the aforementioned automatic liquid collection mechanism, the bottom of the mounting bracket is provided with a connecting plate, and the connecting plate has an oblong hole through which fasteners pass to fix the connecting plate to the chassis.

[0018] The technical solution adopted by this utility model to solve its technical problem is to also propose a machine tool, including one of the above-mentioned automatic liquid collection mechanisms.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) The present invention provides an automatic liquid collection mechanism and machine tool by connecting the siphon assembly into the return pipeline of the spray pump and using the flow of the return liquid to form a local negative pressure at the connection point. Without the need for additional vacuum pump or independent suction device, it can achieve efficient collection of leaked liquid outside the machine box. The overall structure is simple, energy-saving, environmentally friendly, safe and reliable, ensuring the stability and reliability of equipment operation.

[0021] (2) The connecting pipe connects the inlet pipe of the return pipeline to the flow regulating valve, realizing the centralized installation and fixation of key components of the return assembly, making the pipeline route clear and the layout regular, reducing pipeline bends and stress concentration, and improving connection reliability.

[0022] (3) The filter screen can effectively intercept particulate impurities (such as metal shavings, dust, etc.) mixed in the leaked liquid, preventing them from entering the siphon pipe and return pipe with the liquid, thereby avoiding pipe blockage or valve jamming and ensuring long-term stable operation of the system.

[0029] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0030] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0031] like Figure 1 As shown, this solution mainly describes an automatic liquid collection mechanism for use on machine tools. However, this automatic liquid collection mechanism is not limited to use in machine tools, but can also be applied to other equipment that requires liquid collection.

[0032] like Figures 1 to 2 As shown, an automatic liquid collection mechanism includes a housing 1, a spray pump 2, a return flow assembly 3, and a siphon assembly 4.

[0033] The spray pump 2 is mounted on the casing 1, and its output end is connected to the spray pipe fitting 20. The spray pump 2 is used to draw liquid from the casing 1 and transport it to the spray pipe fitting 20. The return assembly 3 includes a flow regulating valve 30 and a return pipe 31. One end of the return assembly 3 is connected between the spray pipe fitting 20 and the output end of the spray pump 2, and the other end is connected to the return pipe 31, which is connected to the casing 1. The flow regulating valve 30 is used to regulate the flow rate of liquid flowing into the return pipe 31. The siphon assembly 4 is located outside the casing 1. One end of the siphon assembly 4 is connected to the suction plate 40, and the other end is connected to the return pipe 31. When the spray pump 2 is running, flowing liquid is formed in the return pipe 31. A negative pressure zone is generated at the connection point between the siphon assembly 4 and the return pipe 31, so that externally leaked liquid is sucked in through the suction plate 40 and transported into the casing 1 through the return pipe 31.

[0034] like Figures 1 to 2 As shown, when the equipment is started, the spray pump 2 begins to work, drawing liquid from the casing 1 and delivering it to the spray pipe fitting 20 through its output end to perform normal spray cleaning or cooling operations. During this process, some liquid is diverted to the return assembly 3. After the flow rate is regulated by the flow regulating valve 30, the diverted liquid enters the return pipe 31 and eventually returns to the inside of the casing 1, forming a stable return cycle (i.e., the liquid in the return pipe 31 maintains a certain flow rate under the drive of the spray pump 2). Furthermore, because the return pipe 31 is also connected to the siphon assembly 4, the flowing liquid formed in the return pipe 31 during the operation of the spray system creates a negative pressure zone, driving the siphon assembly 4 to automatically suck in external leaked liquid and return it to the casing 1. This structure eliminates the need for an additional independent suction pump or vacuum device, achieving automatic collection of leaked liquid, significantly reducing equipment costs and energy consumption, and improving the system's integration and automation level. Meanwhile, the flow regulating valve 30 can precisely control the return flow rate, thereby adjusting the negative pressure intensity to ensure the siphon function is stable and reliable, adapting to the liquid recovery needs under different working conditions.

[0035] The siphon assembly 4 also includes a siphon tube 41 and a liquid receiving box 42. The outer wall of the return pipe 31 has a liquid inlet 310. One end of the siphon tube 41 is connected to the liquid suction plate 40, and the other end is connected to the liquid inlet 310. The liquid suction plate 40 is placed inside the liquid receiving box 42.

[0036] like Figure 1 and Figure 2As shown, based on the above, by setting a siphon pipe 41 to connect the liquid suction plate 40 and the liquid inlet 310 on the return pipe 31, and placing the liquid suction plate 40 inside the liquid receiving box 42, the external leaked liquid first collects in the liquid receiving box 42, and then is sucked into the return pipe 31 by siphon action. At the same time, the liquid inlet 310 is located on the outer wall of the return pipe 31, which facilitates installation and maintenance, has a compact structure, and is conducive to the optimization of the overall layout. It should be noted that the liquid receiving box 42 in this embodiment can be an oil receiving box or used to store cutting fluid or other liquids. Furthermore, the return pipe 31 in this embodiment has an overall funnel-shaped design (i.e., the large end connects to the chassis 1, and the small end is close to the connection between the siphon pipe 41 and the return pipe 31; the entire structure has a diffuser design, not shown in the figure). Because of this, when the liquid flows from the return assembly 3 into the return pipe 31, a negative pressure is generated due to the collision phenomenon caused by the throat structure (i.e., the small end inlet of the return pipe). This negative pressure draws in the leaking liquid from the liquid receiving box 42, which, along with the driving liquid originally flowing into the return channel, flows together into the chassis 1. The formation of this negative pressure and the structure and working principle of the siphon phenomenon can be found in existing technologies and will not be described in detail here.

[0037] Preferably, this embodiment also provides a filter screen inside the liquid suction tray 40, which can effectively intercept particulate impurities (such as metal shavings, dust, etc.) mixed in the leaked liquid, preventing them from entering the siphon pipe 41 and return pipe 31 with the liquid, thereby avoiding pipe blockage or valve jamming, ensuring long-term stable operation of the system. In addition, the filter screen has a simple structure, is easy to disassemble and clean, and is convenient to maintain, further improving the reliability and service life of the equipment.

[0038] The end of the reflux assembly 3 is connected to a T-shaped port 32, and the two ends of the T-shaped port 32 are used to connect the spray pipe fitting 20 and the output end of the spray pump 2.

[0039] like Figure 2 As shown, in this embodiment, a T-shaped port 32 is provided at the end of the return assembly 3 to achieve a three-way connection between the output end of the spray pump 2 and the spray pipe fitting 20, so that a portion of the liquid is diverted into the return pipe 31 to form a stable return path. The T-shaped port 32 has a simple structure, low fluid resistance, and reliable connection, which is conducive to maintaining the pressure balance between the main spray circuit and the return siphon circuit, ensuring that the spray operation and liquid recovery function do not interfere with each other and operate synchronously and efficiently.

[0040] The sprinkler fitting 20 includes a quick-connect pipe 200 and a control valve 201. The T-port 32 and the quick-connect pipe 200 are connected by the control valve 201.

[0041] like Figure 2As shown, in this embodiment, a control valve 201 is added between the T-shaped port 32 and the quick-connect pipe 200, which can realize precise control of the liquid flow during spraying. At the same time, the design of the quick-connect pipe 200 supports quick disassembly and assembly of the spray pipe fittings 20, improving maintenance efficiency. In addition, the combined use of the control valve 201 and the T-shaped port 32 enhances the system's operational flexibility and safety.

[0042] like Figure 1 and Figure 2 As shown, in this embodiment, a liquid pipe 33 is added between the T-shaped port 32 and the flow regulating valve 30, realizing a flexible or standardized connection between the components of the reflux assembly 3. This facilitates layout adjustments based on the actual installation space and reduces assembly difficulty. The liquid pipe 33 can be in the form of a flexible hose or a rigid pipe, offering strong adaptability. It also helps to mitigate fluid pulsation, reduce system vibration and noise, and improve operational stability.

[0043] The chassis 1 is also equipped with a mounting bracket 11. The top of the mounting bracket 11 is equipped with a connecting pipe 12. The top of the return pipe 31 is connected to the liquid inlet pipe 311. One end of the connecting pipe 12 is connected to the liquid inlet pipe 311, and the other end is connected to the flow regulating valve 30.

[0044] like Figure 2 As shown, in this embodiment, by setting a mounting bracket 11 on the chassis 1 and a connecting pipe 12 on its top, the liquid inlet pipe 311 of the return pipe 31 is connected to the flow regulating valve 30, realizing the centralized installation and fixation of the key components of the return assembly 3. This structure makes the pipeline route clear and the layout regular, reduces pipe bends and stress concentration, and improves connection reliability. At the same time, the mounting bracket 11, as an independent module, is easy to assemble and disassemble as a whole, which is conducive to improving production efficiency and convenience of later maintenance.

[0045] The bottom of the mounting bracket 11 is provided with a connecting plate 110, and the connecting plate 110 has an oblong hole 110a for fasteners to pass through, so as to fix the connecting plate 110 to the chassis 1.

[0046] Furthermore, such as Figure 1 and Figure 2 As shown, in this embodiment, a connecting plate 110 with a waist-shaped hole 110a is provided at the bottom of the mounting bracket 11. This allows the mounting bracket 11 to be adjusted to fit the installation position after fine-tuning by locking the fasteners at different positions of the waist-shaped hole 110a. This adapts to different specifications of the chassis 1 or on-site installation errors, ensuring that the return pipe 31 is accurately aligned with other components. This design improves the assembly tolerance and structural adaptability, and enhances the versatility and ease of installation of the equipment.

[0047] Preferably, this embodiment also provides several plugs 10 on the chassis 1 to seal unused interfaces or reserved holes, prevent external contaminants from entering the interior of the chassis 1, and keep the interior clean; at the same time, the plugs 10 can be removed to connect new components when the equipment is upgraded or its functions are expanded, which improves the versatility and scalability of the chassis 1; the plugs 10 have a simple structure, good sealing performance, low cost, and are easy to mass-produce and configure on site.
