Description

Technical Field

[0001] The utility model belongs to the field of emulsions, relates to emulsion filtering technology, and specifically is an emulsion filtering device. Background Art

[0002] Emulsion is a high-performance semi-synthetic metalworking fluid that is widely used in industries such as machining, metal rolling, and automobile manufacturing.

The recovered emulsion can be input into the filter barrel through a one-way valve. The one-way valve can prevent the backflow of the emulsion. When the liquid level of the emulsion reaches the pressure ring, the filter screen on the surface of the pressure ring can filter the sludge impurities in the emulsion. The purified emulsion can be discharged through the output pipe. The precipitated impurities are concentrated to the drain valve under the action of gravity and can be discharged uniformly later.

[0004] However, when implementing the above technical solution, there are the following problems: the device in the above solution is difficult to apply to the emulsion filtration and recovery under certain conditions; the filtered emulsion in the above device will be discharged from the top of the filter barrel, and the emulsion contains an aqueous phase and an oil phase. Under normal circumstances, the two are mixed evenly, or after the two are separated, due to the density difference, the oil is suspended on the surface of the emulsion. The above device will discharge the oil and emulsion simultaneously, but when the emulsion is used many times, when the oil content therein is too high, it may lead to reduced lubrication performance, weakened cooling effect and reduced rust prevention performance. In this case, it is necessary to separate the oil in the emulsion separately.

[0027] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] like Figure 1-5 As shown, an emulsion filtering device includes a filter box 1, wherein a filtering mechanism is provided inside the filter box 1, and the filtering mechanism includes:

[0029] An inlet 21 and a discharge port 22, wherein the inlet 21 is opened at the top of the filter box 1, and the discharge port 22 is opened on the side of the filter box 1 near the bottom, and the inlet 21 and the discharge port 22 are located on different vertical lines;

[0030] A drain outlet 23 is provided at the bottom of the filter box 1. The height of the drain outlet 23 is lower than that of the discharge outlet 22. The end of the drain outlet 23 near the filter box 1 contacts the end of the discharge outlet 22 near the filter box 1. There is partial contact between the drain outlet 23 and the discharge outlet 22, so that the height of the drain outlet 23 near the filter box 1 is the same as the height of the discharge outlet 22 away from the filter box 1. The emulsion inside the filter box 1 can be selectively discharged through the drain outlet 23 and the discharge outlet 22.

[0031] A plurality of barrier blocks 24 are fixedly connected to the discharge port 22 and the sewage outlet 23 through fixing components. A filter screen 25 is fixedly provided inside the discharge port 22 through a fixing component. The barrier blocks 24 inside the discharge port 22 are close to the filter box 1.

[0032] An observation block 26 is fixedly connected to the filter box 1 and is made of a material such as glass. The observation block 26 is transparent and allows for direct observation of the interior of the filter box 1. The height of the end of the observation block 26 away from the sewage outlet 23 is lower than the height of the end of the discharge port 22 away from the sewage outlet 23. The transparent observation blocks 26 are provided at the discharge port 22 and the sewage outlet 23, so that the state of the emulsion, the amount of impurities, and the boundary between the emulsion and the oil can be observed during the emulsion discharge process, making it easier to control and reduce the discharge of oil after separation on the emulsion surface.

[0033] In actual use, the emulsion filtering device is configured such that the emulsion is poured in from above and discharged from below through an inlet 21 provided at the top of the filter box 1 and a discharge port 22 near the bottom of the filter box 1. After the emulsion has settled, the oil is located above the emulsion, which can directly ensure that the oil is not discharged at the same time as the emulsion. A sliding barrier block 24 and a filter screen 25 are provided inside the discharge port 22, and a sewage outlet 23 is provided at the bottom of the filter box 1, thereby flexibly controlling the discharge of the emulsion and directly discharging impurities downward. At the same time, observation blocks 26 are provided at the two discharge positions, which allow for intuitive understanding of the discharge process and control of the separate discharge of the emulsion and oil. The discharge conditions of the oil and emulsion can be more flexibly controlled, thereby ensuring the quality of the filtered emulsion.

[0034] In some specific embodiments, the fixing assembly includes a sliding block 31, which is slidably connected to the inside of the blocking block 24. A locking groove 32 is provided inside the sewage outlet 23 or the discharge outlet 22, and the locking groove 32 is adapted to the blocking block 24; two fixing columns 33 are slidably connected to the inside of the blocking block 24, and the opposite surfaces of the two fixing columns 33 are fixedly connected to fixing springs 34. A connecting belt 35 is fixedly connected between the fixing columns 33 and the sliding block 31. A plurality of fixing grooves 36 are provided inside the sewage outlet 23 and the discharge outlet 22, and the fixing grooves 36 are adapted to the fixing columns 33;

[0035] In a further embodiment, there are at least four fixing grooves 36 inside the sewage outlet 23 and the discharge outlet 22, and the fixing grooves 36 are divided into two groups. The two groups of fixing grooves 36 are arranged at intervals inside the sewage outlet 23 and the discharge outlet 22; thus, the fixing column 33 can contact and approach the fixing grooves 36 at different positions, thereby fixing the blocking block 24 at different positions on the sewage outlet 23 or the discharge outlet 22;

[0036] In some specific embodiments, a motor 41 is fixedly connected to the top of the filter box 1, and the motor 41 is electrically connected to an external power supply. One end of the output shaft of the motor 41 is fixedly connected to a coupling (not shown in the figure). A stirring paddle 42 is rotatably connected to the inside of the filter box 1, and one end of the stirring paddle 42 is fixedly connected to the coupling (not shown in the figure). A feeding trough 43 is provided on the surface of the filter box 1; a certain amount of demulsifier can be added to the interior of the filter box 1 through the feeding trough 43. Through the stirring of the demulsifier and the stirring paddle 42, the demulsifier and the oil in the emulsion can be combined to form flocs, which will float on the surface of the emulsion, further advancing the oil inside the emulsion;

[0037] The working principle of the utility model is as follows: before use, the blocking blocks 24 inside the sewage outlet 23 and the discharge port 22 are first inserted into the inside, and the blocking blocks 24 inside the sewage outlet 23 and the discharge port 22 prevent the sewage from being discharged downward;

[0038] During use, the emulsion is poured into the filter box 1 from the input port 21. After a certain amount is poured in, the operation is stopped and the filter box 1 is allowed to stand. Alternatively, a certain amount of demulsifier is added from the feeding trough 43. After the demulsifier is added, the motor 41 is started. The motor 41 drives the stirring paddle 42 to rotate, causing the oil in the emulsion to mix with the demulsifier to form flocs. After stirring for a period of time, the stirring is stopped and the filter box is allowed to stand. After a period of time, the filter screen 25 is inserted into the discharge port 22, and the sliding block 31 inside the blocking block 24 at the discharge port 22 is pulled. The sliding of the sliding block 31 pulls the fixed columns 33 closer to each other through the connecting belt 35, and the fixed columns 33 are separated from the fixed groove 36. Then the blocking block 24 is pulled to allow the discharge port 22 to discharge the emulsion. The discharged emulsion passes through the filter screen 25 and is discharged to block impurities.

[0039] If oil separation is required, observe the separation line of oil and emulsion at the position of observation block 26 and reset the blocking block 24 in time; after the emulsion and oil are completely discharged, slide the blocking block 24 at the position of the drain outlet 23 to discharge impurities from the drain outlet 23.

[0040] The above embodiments are only used to illustrate the technical method of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
