Description

Technical Field

[0001] The utility model belongs to the technical field of processing equipment and relates to a belt type oil-water separator. Background Art

[0002] The machine tool oil-water separator is a purification treatment device for the cutting fluid of a machine tool. Its main function is to separate oil and water in the cutting fluid, so as to extend the service life of the cutting fluid. At present, the commonly used oil-water separators are: belt type oil-water separator or rotary disk type oil-water separator.

[0003] For example, a belt type oil-water separator disclosed in the Chinese patent document [Publication No.: CN 203741097 U] includes a housing, a treatment liquid tank, a driving motor, a driving pulley, a driven pulley, a lifting belt and a driven pulley connecting rod. A driving pulley scraper is installed below the driving pulley. The driving pulley scraper is attached to the working surface of the driving pulley to scrape off the grease adhered to the surface of the driving pulley in time. The upper end of the driven pulley connecting rod is connected to a lifting belt scraper, and the lifting belt scraper scrapes off the grease adhered to the lifting belt.

[0004] When the lifting belt scraper scrapes oil from the lifting belt, a planing effect will be generated, and the lifting belt is prone to damage, especially the belt made of polymer materials, which will affect the service life. In order to reduce the damage of the belt, the usual method is to replace the lifting belt with a metal material, that is, to replace the belt with a steel belt. For example, a steel belt type vertical oil-water separator with the publication number of CN208641856 U. However, the oil affinity of the metal material is not as good as that of the polymer material, which reduces the oil-water separation effect of the steel belt type oil-water separator. Summary of the Utility Model

[0005] The purpose of the present utility model is to propose a belt type oil-water separator in view of the above problems existing in the prior art, and the technical problem to be solved is how to improve the service life of the belt of the oil-water separator.

[0006] The purpose of the present utility model can be achieved by the following technical solutions:

[0007] A belt type oil-water separator includes an outer cover. A motor and a mounting plate are fixed on the outer cover. A driving wheel connected to the motor is installed inside the outer cover. The lower end of the mounting plate extends out of the outer cover and is connected to a driven wheel. A belt is connected between the driving wheel and the driven wheel. A scraper plate made of metal material and inclined is also fixed on the outer cover. It is characterized in that the upper end of the scraper plate bends towards the lower surface of the scraper plate and forms a abutting part at the bending position. The length of the abutting part is arranged along the axial direction of the driving wheel, and the outer side surface of the abutting part abuts against the outer side surface of the belt.

[0008] After being bent, the oil scraping plate made of metal material will form an arc structure at the bent part, that is, the outer side of the abutting part is an arc surface. In this way, the outer side of the abutting part abuts against the outer side of the belt, that is, the arc surface abuts against the belt, which can greatly reduce the planing effect of the oil scraping plate on the belt, reduce the damage of the belt caused by the planing effect of the oil scraping plate, and improve the service life of the belt. The length of the abutting part is arranged along the axial direction of the driving wheel, which can make the position of the belt abutting against the abutting part receive uniform force, thus avoiding fatigue damage caused by uneven force on the belt and also being beneficial to improving the service life of the belt. Therefore, this belt type oil-water separator can improve the service life of the belt.

[0009] In the above-mentioned belt type oil-water separator, the length of the abutting part is greater than the width of the belt. This can ensure the contact length between the abutting part and the belt, ensure the oil scraping effect; and can further ensure the uniformity of the force on the belt, avoid fatigue damage caused by uneven force on the belt, and is beneficial to improving the service life of the belt.

[0010] In the above-mentioned belt type oil-water separator, a junction box is fixedly connected to the outer side of the outer cover, a control switch for controlling the motor switch is fixedly connected in the junction box, and a switch operating member extending out of the junction box is provided on the control switch.

[0011] In the prior art, the machine tool water tank is generally located at the bottom of the machine tool and extends backward, and the oil-water separator is installed on the water tank of the machine tool at the rear of the machine tool. The control switch of the oil-water separator is generally centrally arranged on the control panel together with the control switches of other mechanisms of the machine tool, and the control panel is arranged on the front of the machine tool. Therefore, when it is necessary to start the oil-water separator for oil removal, it is necessary to first turn on the oil-water separator through the control panel, and then walk from the front of the machine tool to the rear of the machine tool to check whether the oil-water separator is working properly. When it is found that the oil-water separator located at the rear of the machine tool fails and needs to be stopped, it is necessary to walk from the rear of the machine tool to the front of the machine tool, and then turn off the oil-water separator through the control panel. The convenience of controlling the switch of the oil-water separator in the prior art is insufficient.

[0012] In this belt-type oil-water separator, the control switch can be a toggle switch or a rocker switch, and the switch operating member is the toggle on the toggle switch or the rocker on the rocker switch. The outer cover is fixedly connected to the water tank, and the driven wheel is inserted into the water tank. When it is necessary to start the oil-water separator for oil removal, walk to the rear of the machine tool and operate the switch operating member to start the motor. The motor works, the driving wheel rotates, and drives the driven wheel to rotate through the belt. The movement of the belt brings the oil in the cutting fluid to the oil scraping plate, and the oil scraping plate scrapes off the oil. After starting, it is possible to directly observe whether the oil-water separator is working properly without moving. When it is found that the oil-water separator fails and needs to be stopped, directly operate the switch operating member to turn off the motor without moving. Observation and switch operation can be carried out simultaneously without walking back and forth. Therefore, the convenience of switch control of this belt-type oil-water separator is improved. In addition, when the liquid level of the coolant is lower than the driven wheel, dry friction will occur between the oil scraping plate and the belt. After installing the control switch on the outer cover, the operator can only walk to the water tank to start the oil-water separator, so that the coolant condition of the water tank can be detected in time when starting, avoiding dry friction between the oil scraping plate and the belt caused by starting the oil-water separator when the coolant is insufficient, and also being beneficial to improving the service life of the belt.

[0013] In the above-mentioned belt-type oil-water separator, a window is opened on the front side surface of the outer cover, the oil scraping plate extends out from the window, the motor is fixedly connected to the left side surface of the outer cover, the junction box is fixedly connected to the right side surface of the outer cover, and the switch operating member is located on the front side surface of the junction box or on the right side surface of the junction box. The operator stands in front of the outer cover, and the right hand can easily operate the switch operating member and can also easily observe the contact situation between the oil scraping plate and the belt through the window. When it is found that the contact between the oil scraping plate and the belt is abnormal, the right hand can casually operate the switch operating member to turn off the motor. Therefore, such a setting can further improve the convenience of switch control of the oil-water separator and can also timely turn off the oil-water separator to reduce the damage to the belt caused by the abnormal contact between the oil scraping plate and the belt, which is beneficial to improving the service life of the belt.

[0014] In the above-mentioned belt-type oil-water separator, wiring connectors are provided on both the upper end surface and the lower end surface of the junction box. Such a setting separates the wires on the wiring connectors from the switch operating member, avoiding interference of the wires with the switch operating member and affecting the switch operation.

[0015] In the above-mentioned belt-type oil-water separator, a switch mark corresponding to the switch operating member is provided on the outer surface of the junction box. The switch mark can be in Chinese or English, which is convenient for the operator to know the on / off state of the motor and makes the switch operation convenient.

[0016] In the above-mentioned belt-type oil-water separator, a V-shaped plate is fixed below the driving wheel in the outer cover, the V-shaped plate corresponds to the window, and the opening of the V-shaped plate faces upward. The V-shaped plate is used to catch and buffer the oil dripping from the driving wheel, and the condition of the V-shaped plate can also be observed through the window, which is convenient for understanding the working condition of the belt-type oil-water separator.

[0017] Compared with the prior art, the utility model has the following advantages:

[0018] 1. The upper end of the scraper plate is bent toward the lower surface of the scraper plate and abutment is formed at the bend. The length of the abutment is arranged along the axial direction of the driving wheel. The outer side of the abutment abuts against the outer side of the belt, which greatly reduces the planing effect of the scraper plate on the belt, makes the belt evenly stressed, and improves the service life of the belt.

[0019] 2. A junction box is fixed on the outer surface of the outer cover, and a control switch is installed in the junction box. The operating part of the control switch extends from the junction box. The switch and observation of the belt oil-water separator can be carried out at the same time without walking around, which improves the convenience of switch operation. It can also avoid dry grinding between the scraper and the belt caused by opening the oil-water separator when the coolant is insufficient, which is also beneficial to increase the service life of the belt.

[0020] 3. The window is set on the front side of the outer cover, and the junction box is fixed on the right side of the outer cover, which is convenient for observing and switching the oil-water separator. It can also shut down the oil-water separator in time to reduce the damage to the belt caused by abnormal contact between the scraper and the belt, which is beneficial to prolong the service life of the belt.

DETAILED DESCRIPTION

[0026] The following are specific embodiments of the present utility model and, in conjunction with the accompanying drawings, further describe the technical solutions of the present utility model, but the present utility model is not limited to these embodiments.

[0027] Embodiment 1

[0028] As Figure 1 and Figure 2 shown, a belt-type oil-water separator includes an outer cover 1. A motor 2 is fixed on the left side surface of the outer cover 1. A driving wheel 4 is arranged inside the outer cover 1. The rotating shaft of the motor 2 extends into the outer cover 1 and is connected to the driving wheel 4. The lower end of the outer cover 1 is open. An installation plate 3 is fixedly connected inside the outer cover 1. The lower end of the installation plate 3 extends out of the outer cover 1 and is connected to a driven wheel 5. The installation plate 3 is fixedly connected to the left side wall of the outer cover 1 through bolts. The installation plate 3 abuts against the inner side surface of the outer cover 1. A strip-shaped hole is formed in the installation plate 3 along the up-down direction. After the bolt passes through the strip-shaped hole, it is threadedly connected to the outer cover 1, or after the bolt passes through the strip-shaped hole and the outer cover 1, it is threadedly connected to a nut. To facilitate the connection of the installation plate 3, an installation opening is formed on the right side surface of the outer cover 1, and a detachable sealing plate is fixed at the installation opening. The driven wheel 5 is connected to the installation plate 3 through an axially positioned bolt. After the axially positioned bolt passes through the driven wheel 5 and the installation plate 3, it is threadedly connected to a nut. A belt 6 is connected between the driving wheel 4 and the driven wheel 5. The belt 6 is sleeved on the driving wheel 4 and the driven wheel 5 respectively. The rotation of the driving wheel 4 drives the rotation of the driven wheel 5 through the belt 6. The belt 6 is a lipophilic and hydrophobic TPE belt 6 or TPU belt 6. A scraping oil plate 7 that abuts against the belt 6 is also fixed on the outer cover 1. The scraping oil plate 7 is made of a metal material, such as a stainless steel plate or an aluminum alloy plate. The scraping oil plate 7 is inclined. A window 1a is formed on the front side surface of the outer cover 1. The scraping oil plate 7 extends out from the window 1a. The upper end of the scraping oil plate 7 is located inside the outer cover 1, and the lower end of the scraping oil plate 7 is located outside the outer cover 1. A oil receiving box located in front of the outer cover 1 is also arranged below the scraping oil plate 7. The oil receiving box is used for receiving oil. A V-shaped plate 10 is fixed below the driving wheel 4 inside the outer cover 1. The opening of the V-shaped plate 10 faces upward. As Figure 3 shown, the V-shaped plate 10 corresponds to the window 1a, and the V-shaped plate 10 can be observed through the window 1a.

[0029] As Figure 1 and Figure 3 shown, a junction box 8 is fixedly connected to the right side surface of the outer cover 1. The junction box 8 is located above the cover. Combining Figure 2As shown, a control switch 9 for controlling the switch of the motor 2 is fixedly connected inside the junction box 8. The control switch 9 has a switch operating member 9a extending from the junction box 8, and the switch operating member 9a is located on the front side surface or the right side surface of the junction box 8. A switch mark 8a corresponding to the switch operating member 9a is provided on the outer surface of the junction box 8, and the switch mark 8a can be in Chinese or English, such as "ON" and "OFF" or "Open" and "Close". Wiring connectors 8b are provided on both the upper end surface and the lower end surface of the junction box 8, and the wires on the wiring connectors 8b are respectively connected to the motor 2 and the power supply. The wire of the upper wiring connector 8b [not shown in the figure] is connected to the motor 2, and the wire of the lower wiring connector 8b is connected to the power supply.

[0030] As Figure 2 and Figure 4 shown, the upper end of the oil scraping plate 7 bends towards the lower surface of the oil scraping plate 7 and forms an abutting portion 7a at the bending position. The length of the abutting portion 7a is arranged along the axial direction of the driving wheel 4, and the outer side surface of the abutting portion 7a abuts against the outer side surface of the belt 6. The length of the abutting portion 7a is greater than the width of the belt 6, and both ends of the abutting portion 7a protrude beyond the two side edges of the belt 6. Connecting portions are formed by bending both sides of the oil scraping plate 7 upwards, and the connecting portions are fixedly connected to the outer cover by screws. After the oil scraping plate 7 made of metal material is bent, an arc structure will be formed at the bending position, that is, the outer side surface of the abutting portion 7a is an arc surface. In this way, the outer side surface of the abutting portion 7a abuts against the outer side surface of the belt 6, that is, the arc surface abuts against the belt 6, which can greatly reduce the shaving effect of the oil scraping plate 7 on the belt 6, reduce the damage of the belt 6 caused by the shaving effect of the oil scraping plate 7, and improve the service life of the belt 6. And the length of the abutting portion 7a is arranged along the axial direction of the driving wheel 4, which can make the position of the belt 6 abutting against the abutting portion 7a receive uniform force, thus avoiding fatigue damage caused by uneven force on the belt 6 and also being beneficial to improving the service life of the belt 6. Therefore, this belt type oil-water separator can improve the service life of the belt 6.

[0031] The control switch 9 can be a toggle switch or a rocker switch, and the switch operating member 9a is the toggle of the toggle switch or the rocker of the rocker switch. Both the toggle switch and the rocker switch are existing products and can be directly purchased on the market. The wire connection methods of the toggle switch or the rocker switch to the motor 2 and the power supply can refer to the wiring instructions of the toggle switch or the rocker switch.

[0032] The outer cover 1 is fixedly connected to the water tank, and the driven wheel 5 is inserted into the water tank. The control switch 9 is located inside the junction box 8, and the junction box 8 protects the control switch 9, preventing the control switch 9 from coming into contact with substances such as oil and water, which may affect the safety and reliability of the control switch 9. When it is necessary to start the oil-water separator for oil removal, walk to the rear of the machine tool and operate the switch operating part 9a to turn on the motor 2. When the motor 2 is working, the belt 6 moves to bring the oil in the cutting fluid to the oil scraping plate 7. The oil scraping plate 7 scrapes off the oil and guides the oil to slide into the oil receiving box. After starting, it is possible to directly observe whether the oil-water separator is working properly without moving. When it is found that the oil-water separator fails and needs to be stopped, directly operate the switch operating part 9a to turn off the motor 2 without moving. Observation and switch operation can be carried out simultaneously without walking back and forth. Therefore, this oil-water separator improves the convenience of switch control.
