Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for mechanical processing, and in particular to a three-sided shielded oil mist suction and discharge filtration device. Background Technology

[0002] Both oil and water used in machining are essentially heat transfer media, and their cooling principle is the same: cooling by removing heat from machine tool parts. Because oil has a much higher specific heat capacity than water, it can remove more heat for the same volume, making oil a better heat dissipation medium than water.

[0003] Currently, some oil-cooled machining equipment is prone to generating oil mist during parts processing. The spread of oil mist can seriously harm the operator's health. Therefore, most oil-cooled machining equipment is equipped with an oil mist extraction mechanism to treat the oil mist. In order to reduce the spread of oil mist to the outside, most current oil mist extraction devices are equipped with a certain length of vertical rubber curtains on the rear and left and right sides for blocking. However, when installing the rubber curtains, the traditional method is to fix them with bolts after opening holes at the ends. However, this structure has the following problems: as the width increases, the number of openings increases, and the number of connecting bolts will increase significantly. The subsequent maintenance and disassembly of a single rubber curtain is very inconvenient. Utility Model Content

[0004] The purpose of this utility model is to provide a three-sided shielded oil mist suction and discharge filter device, which aims to solve the problem that when the width of the rubber curtain increases, the number of openings increases significantly, the number of connecting bolts increases significantly, and the subsequent maintenance and disassembly of a single rubber curtain is very inconvenient.

[0005] To achieve the above objectives, this utility model provides a three-sided shielding oil mist suction and discharge filtration device, including a main conveying pipe, which is hoisted and installed in the equipment working area of ​​the workshop by a hoisting bracket, and also includes shielding components;

[0006] The shielding assembly includes a connecting pipe, a processing box, a horn cover, a positioning plate, a positioning pin, a shielding curtain, a fixing plate, and a processing component. The connecting pipe is detachably connected to the main conveying pipe and the processing box. The horn cover is installed on the bottom inlet side of the processing box. The positioning plate is detachably connected to the horn cover. The positioning pin is threaded to the positioning plate and arranged in multiple single-line intervals. The shielding curtain is detachably connected to the positioning pin and is limited by the fixing plate. The fixing plate is detachably connected to the positioning plate. The processing component is located on one side of the processing box.

[0007] The front side of the speaker cover may also be provided with the positioning plate, the positioning pin, the shielding curtain and the fixing plate, but the vertical length of the shielding curtain on this side will be shorter than the length of the shielding curtains on the rear side and the left and right sides of the speaker cover.

[0008] The processing component includes an extraction fan, an inclined baffle, an oil mist filter, and a discharge component. The extraction fan is installed below the air outlet at the top of the processing box. The inclined baffle is welded inside the processing box. The oil mist filter is installed on the top of the processing box, near the highest point of the inclined baffle. The discharge component is located behind the lowest point of the collection cavity formed by the processing box and the inclined baffle.

[0009] The discharge component includes a discharge pipe and an electric valve. The discharge pipe is detachably connected to the processing box and communicates with the collection chamber formed by the processing box and the inclined baffle. The electric valve is installed on the oil outlet side of the discharge pipe and its oil outlet side is connected to an external oil return pipe.

[0010] The three-sided shielded oil mist suction and discharge filtration device also includes a monitoring component, which includes a liquid level sensor and an alarm indicator light. The liquid level sensor is installed on the processing tank, and the alarm indicator light is installed on the processing tank.

[0011] This utility model discloses a three-sided shielding oil mist suction and filtration device. During installation of the shielding curtain, positioning pins are first installed at intervals on the positioning plate at corresponding positions. Furthermore, the mounting holes on the shielding curtain can be directly slidably inserted into the positioning pins, corresponding one-to-one. At this point, the shielding curtain is flush with the stepped portion at the bottom of the positioning plate and the limiting end face on the positioning pin. Then, a fixing plate is fixed with two bolts, with the fixing plate corresponding to each shielding curtain. After installation, the fixing plate abuts against the limiting end face on the positioning pin, thereby limiting the position of a single shielding curtain. When disassembling the corresponding shielding curtain, the two fixing bolts on the fixing plate at the corresponding position are removed, and then the corresponding shielding curtain can be directly removed. This solves the problem that existing oil mist treatment devices, as the width of the curtain increases, require more openings and a significantly increased number of connecting bolts, making subsequent maintenance and disassembly of a single curtain extremely inconvenient.

Detailed Implementation

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] Example 1:

[0020] like Figures 1 to 3 As shown, where Figure 1 This is a schematic diagram of the overall structure of a three-sided shielded oil mist suction and discharge filter device. Figure 2 This is a structural schematic diagram of the fixing plate 108. Figure 3 This is a cross-sectional view of the processing box 103. This utility model provides a three-sided shielded oil mist suction and discharge filtration device: it includes a main conveying pipe 101 and a shielding assembly. The shielding assembly includes a connecting pipe 102, a processing box 103, a horn cover 104, a positioning plate 105, a positioning pin 106, a shielding plastic curtain 107, a fixing plate 108, and processing components. The processing components include an extraction fan 109, an inclined baffle 110, an oil mist filter 111, and a discharge component. The discharge component includes a discharge pipe 112 and an electric valve 113. This solution solves the problem in existing oil mist treatment devices where, as the width of the plastic curtain increases, the number of openings increases significantly, leading to a substantial increase in the number of connecting bolts and making subsequent maintenance and disassembly of a single plastic curtain very inconvenient. It is understood that the aforementioned solution facilitates the installation, disassembly, and maintenance of a single shielding plastic curtain 107.

[0021] In this embodiment, the main conveying pipeline 101 is hoisted and installed in the equipment working area of ​​the workshop by a hoisting bracket. The main conveying pipeline 101 is used to centrally process and convey the oil mist gas extracted by multiple devices.

[0022] The connecting pipe 102 is detachably connected to the main conveying pipe 101 and the processing box 103 respectively. The horn cover 104 is installed on the bottom inlet side of the processing box 103. The positioning plate 105 is detachably connected to the horn cover 104. The positioning pin 106 is threadedly connected to the positioning plate 105 and arranged in multiple single-line intervals. The shielding curtain 107 is detachably connected to the positioning pin 106 and is limited by the fixing plate 108. The fixing plate 108 is detachably connected to the positioning plate 105. The processing component is located on one side of the processing box 103. The flanges on both sides of the connecting pipe 102 are fixed with bolts, forming a ventilation duct structure between the treatment box 103 and the main conveying pipe 101. The positioning plate 105 is fixed to the treatment box 103 with bolts, and a stepped groove is provided at its bottom. The positioning pins 106 are directly installed on the stepped groove by rotating with an Allen wrench and are arranged in a straight line with a diameter consistent with the diameter of multiple mounting holes of the shielding curtain 107. The fixing plate 108 is fixed with two bolts. Because the shielding curtain 107 has a certain length, traditional installations would provide multiple bolt holes at its ends to ensure the sealing of the end fit, and then fix it with bolts. This would result in a large number of bolts for subsequent disassembly. In this structure, the fixing plate 108 is fixed with two bolts, which makes subsequent disassembly more convenient. At the same time, in order to facilitate the disassembly of multiple shielding curtains 107 together, the fixing plate 108 can also be set as an integral structure, with the number of bolts minimized while ensuring stability according to the corresponding length, which will directly facilitate the disassembly of multiple curtains. The treatment component is used to extract and treat oil mist. The shielding curtain 107 is made of oil-resistant rubber.

[0023] Secondly, the front side of the speaker cover 104 can also be provided with the positioning plate 105, the positioning pin 106, the shielding curtain 107, and the fixing plate 108. However, the vertical length of the shielding curtain 107 on this side will be shorter than the length of the shielding curtains 107 on the rear and left and right sides of the speaker cover 104. Since the front of the device needs to be loaded during installation, the above structure can also partially block the front without interfering with loading and unloading the component.

[0024] Then, the extraction fan 109 is installed below the air outlet at the top of the processing box 103; the inclined baffle 110 is welded inside the processing box 103; the oil mist filter 111 is installed on the top of the processing box 103 and near the highest point of the inclined baffle 110; the discharge component is located behind the lowest point of the collection cavity formed by the processing box 103 and the inclined baffle 110. The extraction fan 109 is bolted into the processing box 103. A cable matching hole is provided on the rear side of the processing box 103, and a sealing ring is installed in the hole for sealing and connection, allowing the cable of the extraction fan 109 to pass through. The inclined baffle 110 is welded into the processing box 103. During the processing of the processing box 103, the inclined baffle 110 is welded and fixed first, then the top sealing plate is welded, and finally a maintenance door is provided on its rear side for the installation and maintenance of the extraction fan 109. The oil mist filter 111 is bolted in, and its working part extends into the processing box 103. Specifically, the oil mist filter 111 can adopt existing technology, such as the device disclosed in existing technology CN206609014U, for oil mist filtration. Its oil mist treatment structure and principle are existing technology and will not be described in detail here. The discharge component is used to control the discharge of the collected oil.

[0025] Finally, the discharge pipe 112 is detached from the processing tank 103 and communicates with the collection chamber formed by the processing tank 103 and the inclined baffle 110; the electric valve 113 is installed on the oil outlet side of the discharge pipe 112, and its oil outlet side is connected to the external return oil pipeline. The discharge pipe 112 is I-shaped, the fixing flange is fixed to the processing tank 103 by bolts, the connecting flange is connected to the connecting flange of the electric valve 113 by screws and nuts, the connecting flange of the electric valve 113 is connected to the flange on the external oil conveying pipeline, and the electric valve 113 is connected to the external electrical control cabinet through the power line. The electrical control cabinet is equipped with a control PLC, and the electric valve 113 can be automatically discharged by controlling the timer built into the control PLC to operate.

[0026] To address the problem of existing oil mist treatment devices where the number of openings and connecting bolts increases significantly with the width of the rubber curtain, making subsequent maintenance and disassembly of a single rubber curtain extremely inconvenient, this invention first connects the device accordingly. After setup, the horn cover 104 is positioned above the equipment. During oil mist treatment, the extraction fan 109 is controlled to generate suction, extracting the oil mist generated by the equipment's oil cooling. The oil mist enters the treatment box 103 through the horn cover 104 and is filtered by the oil mist filter 111. Finally, it is input into the main delivery pipe 101 through the connecting pipe 102. When installing the shielding rubber curtain 107, the positioning pins 106 are pre-installed at corresponding positions on the positioning plate 105 in a row. Furthermore, the mounting holes on the shielding rubber curtain 107 can be directly connected to the... The positioning pins 106 are slidably inserted and correspond one-to-one. At this time, the shielding curtain 107, the stepped part at the bottom of the positioning plate 105, and the limiting end face on the positioning pin 106 are all flush. Then, the fixing plate 108 is fixed on by two bolts. The fixing plate 108 is set one-to-one with the shielding curtain 107 and abuts against the limiting end face on the positioning pin 106 after installation, thereby limiting the position of a single shielding curtain 107. When the corresponding shielding curtain 107 is subsequently disassembled, the two fixing bolts of the fixing plate 108 at the corresponding position are removed, and then the corresponding shielding curtain 107 can be directly removed. This solves the problem that when the width of the curtain increases, the number of openings increases significantly, the number of connecting bolts increases significantly, and the subsequent maintenance and disassembly of a single curtain is very inconvenient.

[0027] Example 2:

[0028] like Figure 4 As shown, where Figure 4 This is a schematic diagram of the overall structure of a three-sided shielded oil mist suction and discharge filter device. Based on the first embodiment, this utility model provides a three-sided shielded oil mist suction and discharge filter device, which also includes a monitoring component, including a liquid level sensor 201 and an alarm indicator light 202.

[0029] The liquid level sensor 201 is installed on the processing tank 103; the alarm indicator light 202 is installed on the processing tank 103. The liquid level sensor 201 is used to monitor the liquid level of the oil accumulated inside the processing tank 103 and is connected to an external control PLC. The alarm indicator light 202 is fixed by bolts and is also connected to an external control PLC.

[0030] In this embodiment, when the electric valve 113 malfunctions and cannot be opened, the liquid level sensor 201 monitors the oil level. When the liquid level is high, the control PLC controls the alarm indicator light 202 to light up. When the operator observes that the alarm indicator light is lit, they know that the electric valve 113 is malfunctioning and that the collected oil in the processing tank 103 is about to reach its limit, which facilitates the timely processing of the collected oil in the processing tank 103.

[0031] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
