The invention provides a slag-removal oil remover which can save the working time of grease discharge of cleaning personnel and improve the working efficiency of the cleaning personnel.

In an embodiment of the present invention, as shown in fig. 2 to 4, the slag trap 10 includes: the oil collecting box comprises a box body 100 and an oil collecting box 200, wherein a water inlet 110 and a water outlet 120 are arranged on the box body 100, the oil collecting box 200 is arranged in the box body 100, an oil inlet 250 for oil to flow into is arranged at the top of the oil collecting box 200, an oil outlet is also arranged on the oil collecting box 200, the water inflow rate of the water inlet 110 is larger than the water outflow rate of the water outlet 120, so that the liquid level in the box body 100 rises, and the oil on the upper layer of the liquid level flows into the oil.

Since the slag-separating oil remover 10 provided by the patent comprises the tank 100 and the oil collecting box 200 arranged in the tank 100, oily sewage flowing into the tank 100, such as dish washing water, can be separated due to different densities of grease and water, and the grease floats on the upper layer of the water surface. As the oily sewage continuously flows into the tank 100 through the water inlet 110, water and grease in the tank 100 are continuously separated. And because the water inlet flow of the water inlet 110 is larger than the water outlet flow of the water outlet 120, the grease can reach the position of the oil inlet 250. Hereinafter, the description will be given by taking the dishwashing water as an example.

When the liquid level of the grease layer reaches the oil inlet 250 of the oil collecting box 200, the water inlet flow of the water inlet 110 is larger than the water outlet flow of the water outlet 120, so that the grease can continuously flow into the oil collecting box 200 through the oil inlet 250. Among them, it should be noted that the liquid of the tank body is divided into three layers, grease, a mixture of grease and water, and water. It should be understood that not only the grease but also the water may be mixed in the flowing grease into the sump case, and the grease mixed with the water is still separated again in the sump case 200, so that the separation degree of the grease from the water can be improved.

Through the mode, the separated grease can be guided into the oil collecting box, so that the separation of water and grease in the water tank is realized, the water in the water tank can be discharged without worrying about the outflow of the grease along with the water. The cleaner cleans the grease in the oil collecting box out of the oil collecting box through the oil discharging hole. Like this to the separation of realization grease and water that can be very thorough improves cleanup crew's work efficiency, effectively avoids the grease to take place along with the condition that water flows.

Wherein, the oil discharge port can be an oil discharge valve 260 arranged on the side wall of the oil collecting box 200

A first drain pipe 500 is communicated with the inside of the box body 100, a second drain pipe 600 is communicated with the inside of the oil collecting box 200, and one end of the first drain pipe 500 and one end of the second drain pipe 600 are both communicated with the water outlet 120; the other end of the first drain pipe 500 faces the bottom of the tank 100, and the other end of the second drain pipe 600 faces the bottom of the tank 100; the first and second drain pipes 500 and 600 are lower than the oil inlet 250, and both the first and second drain pipes 500 and 600 are communicated with the outside atmosphere.

Wherein, it should be understood that one end of the first drain pipe 500 is used for liquid outflow and the other end of the first drain pipe 500 is used for liquid inflow; similarly, one end of the second drainage pipe 600 is used for liquid outflow, and the other end of the second drainage pipe 600 is used for liquid inflow. Thus, the liquid in the tank 100 can be left to the water outlet through the first drain pipe 500 and flow out of the tank 100, and the liquid in the oil collection box 200 can be left to the water outlet through the second drain pipe 600 and flow out of the oil collection box 200.

Meanwhile, it should be understood that the liquid entering the first drain pipe 500 is the liquid at the bottom of the middle tank 100, and specifically, when the liquid level of the tank 100 reaches the highest point of the first drain pipe 500, the liquid at the bottom of the tank 100 will flow upward along the first drain pipe 500 to the water outlet and flow out of the tank 100. Similarly, the liquid entering the second drainage pipe 600 is the liquid at the bottom of the oil collecting box 200, and specifically, when the liquid level of the oil collecting box 200 reaches the highest point of the second drainage pipe 600, the liquid at the bottom of the oil collecting box 200 will flow upward along the second drainage pipe 600 to the water outlet and flow out of the oil collecting box 200.

The operation of the lower slag trap 10 will now be explained in detail. After once washing the dishes, when not having water in box 100, the water that washes the dishes gets into box 100, and the water that washes the dishes like this gathers in will box 100, and box 100's liquid level rises, and the water that washes the dishes simultaneously carries out oil water separating in box 100 in step, and the grease floats on the upper strata of the water that washes the dishes, and the bottom of box 100 is the water after the separation grease, and the juncture between grease and water is oil water mixture certainly. It will also be appreciated that the grease floating above the water surface is relatively thin. As the bowl continues to fill, the liquid level in the tank 100 will continue to rise.

When the amount of the dish washing water is less, the liquid level in the box body 100 rises to a certain degree and does not rise, and the liquid level of the box body 100 does not reach the height of the first drain pipe 500 at the moment, so that the first drain pipe 500 cannot discharge the water at the bottom of the box body 100. The next time the dishwashing water is introduced into the tub 100, the liquid level in the tub 100 is then raised. When the amount of the dishwashing water is large, the liquid level in the cabinet 100 exceeds the height of the first drain pipe 500, so that the water at the bottom of the cabinet 100 flows out of the cabinet 100 through the outlet along the first drain pipe 500. However, since the flow rate from the water outlet 120 is less than the flow rate from the water inlet 110, the liquid level in the tank 100 will continue to rise until the liquid level in the tank 100 rises to the oil inlet 250, so that the grease can flow into the oil collecting box 200 from the oil inlet 250. As the water level in the tank 100 continues to rise, water in the tank 100 also enters the oil collecting box 200, and at this time, the oil collecting box 200 contains not only oil but also water, which has a density greater than that of the oil, and the water is located in the lower layer in the oil collecting box 200. At this time, it should be understood that the first drain pipe 500 is lower than the oil inlet 250, so that a large amount of water in the tank 100 is prevented from entering the oil collecting box 200. When the water in the oil collecting box 100 continuously enters the oil collecting box 200, the liquid level in the oil collecting box 200 continuously rises until the liquid level in the oil collecting box 200 is higher than the second water discharging pipe 600, so that the water at the bottom of the oil collecting box 200 can be discharged out of the oil collecting box 200 from the water outlet 120 through the second water discharging pipe 600, the liquid level in the oil collecting box 200 can be prevented from rising to the oil inlet 250, and the grease in the oil collecting box 200 can flow into the box 100 from the oil inlet 250. Of course, when the dishwashing water enters the water tank 100 next time, grease of the dishwashing water enters the oil collecting box 200 in the above-mentioned flow.

When the water in the tank body 100 enters the oil collecting box 200, the liquid level in the oil collecting box 200 is not higher than that in the second drain pipe 600, at this time, the second drain pipe 600 cannot discharge the liquid in the oil collecting box 200 outwards, and after the next dishwashing water enters the tank body 100, grease in the dishwashing water enters the oil collecting box 200.

At this time, it should be understood that the oil trap 200 can collect grease in the dishwashing water several times.

Wherein, the first drain pipe 500 and the second drain pipe 600 are both communicated with the outside atmosphere. In this embodiment, the slag trap 10 further includes a communicating pipe 700, the communicating pipe 700 has a first port, a second port and a third port, the first port is communicated with the first drain pipe 500, the second port is communicated with the second drain pipe 600, and the third port is communicated with the external atmosphere, so that the air pressure in the tank 100 is balanced with the external atmosphere. This prevents the first drain pipe 500 and the second drain pipe 600 from generating a siphon phenomenon to drain the liquid in the tank 100 and the liquid in the sump case 200.

The first drainage pipe 500 is 1mm to 10mm lower than the oil inlet 250; the second drain pipe 600 is 1mm to 10mm lower than the oil inlet 250. Thus, both the first drain pipe 500 and the second drain pipe 600 are just slightly lower than the oil inlet 250. Therefore, the collection of the dish washing water in the box body 100 is facilitated, the oil-water separation is sufficient, and the grease can enter the oil collecting box 200 more conveniently; and also contributes to the stratification of grease and water in the oil collecting box 200, and prevents the water discharged from the second water discharging pipe 600 from containing grease. Wherein, the first drain pipe 500 is lower than 2mm of the oil inlet 250, and the second drain pipe 600 is lower than 2mm of the oil inlet 250.

The first drain pipe 500 and the second drain pipe 600 are both disposed in an inverted U shape. Specifically, the first drainage pipe 500 includes a first connection section extending transversely, and a first water inlet section and a first water outlet section extending downwardly from two ends of the first connection section, respectively; the second water discharging pipe 600 includes a second connection section extending in a transverse direction, and a second water inlet section and a second water outlet section extending downward from both ends of the second connection section, respectively. It will be appreciated that water at the bottom of the housing 100 enters from the first water inlet section, flows up the first water inlet section, then flows along the first connecting section towards the first water outlet section, and finally flows down the first water outlet section to the water outlet 120. Similarly, the second drainage pipe 600 flows in the same manner.

Further, referring to fig. 2 to 4, in order to facilitate the grease in the box 100 to flow into the oil collecting box 200, in this embodiment, the top of the box 100 has a grease gathering area which is contracted from bottom to top, and the oil inlet 250 of the oil collecting box 200 extends into the grease gathering area. When the liquid level in the box body 100 rises continuously and reaches the grease gathering area, the grease gathering area is arranged in a shrinkage shape from bottom to top, and the density of the grease is smaller than that of water, so that the thickness of the grease on the water can be increased. Thus, the more the liquid level of the grease moves upwards, the thicker the grease layer produced by the grease with the same volume is, so that the grease can conveniently flow into the oil collecting box 200 from the grease gathering area when the liquid level of the grease is higher than the oil inlet 250 of the oil collecting box 200.

Further, referring to fig. 2 and 3, the grease accumulation area will now be described in detail. The box 100 includes the diapire, from the lateral wall that the diapire periphery upwards extends and from the oil guide cover plate 130 of the top slope of lateral wall upwards extension, and the diapire and the lateral wall of box 100 enclose and close the water storage tank that forms splendid attire dish washing water, and the below of oil guide cover plate 130 forms grease and gathers the district.

Further, as shown in fig. 3, the structure of the oil pan 130 will now be described in detail. The oil guide cover plate 130 comprises a top cover plate 131 and a side cover plate 132 extending obliquely downwards from the edge of the top cover plate 131, the lower edge of the side cover plate 132 is connected with the top edge of the peripheral side plate, a grease gathering area is formed below the side cover plate 132, and the orthographic projection of the top cover plate 131 on the horizontal plane falls into the top opening of the oil gathering box 200, so that the outer edge of the top opening of the oil gathering box 200 is larger than the outer edge of the top cover plate 131, the top opening of the oil gathering box 200 is overlapped with the orthographic projection of the side cover plate 132 on the horizontal plane, and because the grease gathering area is formed below the side cover plate 132, grease gathered in the grease gathering area can more easily enter the oil gathering box 200 when the top opening of the oil gathering box 200 is overlapped with the orthographic projection of the side cover plate 132 on the horizontal plane.

Further, as shown in fig. 2, in order to facilitate a cleaner to observe the liquid level of the grease in the oil collecting box 200, in an embodiment of the present disclosure, an outer sidewall of the oil collecting box 200 is attached to an inner sidewall of the box 100, and a transparent liquid level observation window 140 is disposed on the inner sidewall corresponding to a position where the oil collecting box 200 is attached, for example, the liquid level observation window 140 may be made of transparent glass, transparent plastic, or the like.

Specifically, referring to fig. 2 and 5, the oil collecting box 200 includes a bottom wall arranged in a rectangular shape, and a first side wall 210, a second side wall 220, a third side wall 230 and a fourth side wall 240 extending upward from the periphery of the bottom wall, wherein the first side wall 210 and the second side wall 220 are spaced and arranged oppositely in a first direction, and the third side wall 230 and the fourth side wall 240 are spaced and arranged oppositely in a second direction; the first sidewall 210 is attached to an inner sidewall of the tank 100, and a transparent liquid level observation window 140 is disposed at a position of the tank 100 corresponding to the first sidewall 210.

Further, in order to increase the oil inlet area of the oil inlet 250, at least two side walls of the oil collecting box 200 are spaced from the side walls of the box 100 to increase the oil inlet area of the oil inlet 250.

In the first embodiment, as shown in fig. 5, the oil collecting box 200 is disposed in the middle of the box 100 in the second direction, the first sidewall 210 of the oil collecting box 200 abuts against the inner sidewall of the box 100, and the second sidewall 220, the third sidewall 230, and the fourth sidewall 240 of the oil collecting box 200 are spaced apart from the inner sidewall of the box 100, so that three sides of the oil collecting box 200 can take oil, which increases the oil taking area, thereby further saving the working time of oil discharge process of cleaning personnel, and improving the working efficiency of the cleaning personnel, and the larger the space of the box 100 for containing water is, so that the box 100 can store more water. .

In the second embodiment, as shown in fig. 6, the oil collecting box 200 is disposed in the middle of the box 100 in the second direction, the first sidewall 210 and the second sidewall 220 of the oil collecting box 200 abut against the inner sidewall of the box 100, and the third sidewall 230 and the fourth sidewall 240 of the oil collecting box 200 are spaced from the inner sidewall of the box 100, so that oil can be fed to both sides of the oil collecting box 200, the oil feeding area is large, the working time of oil discharge process of cleaning personnel can be further saved, and the working efficiency of the cleaning personnel is improved.

Further, in consideration of the risk that a cleaner cannot observe the thickness of the grease layer in the oil collecting tank in time, in this embodiment, the slag and oil separating and removing device 10 further includes an oil layer thickness sensor 300 and a reminding device, the oil layer thickness sensor 300 is used for detecting the thickness of the grease layer in the oil collecting box 200, and the reminding device is started when the grease layer reaches a preset thickness. Specifically, the oil-out prompt signal includes an audio prompt signal and a light prompt signal, and accordingly, the alarm 330, the buzzer, or a combination thereof is used as the prompting device. Thus, after the oil layer thickness sensor 300 detects that the grease in the oil collecting box 200 reaches a certain thickness, that is, the grease amount in the oil collecting box 200 can reach a certain amount, the reminding device informs a cleaner to clean the oil collecting box 200. In this way, the grease in the oil collecting box 200 can be prevented from being accumulated too much, so that the grease flows out from the second drainage pipe 600 or flows into the box body 100; frequent cleaning of the oil collection box 200 to avoid excessive grease build up due to unknown grease levels in the oil collection box 200 can also be avoided.

Specifically, the oil layer thickness sensor 300 includes a floating ball device 310 and a conductive sensor 320, the floating ball device 310 is used for detecting the upper liquid level of the oil layer, and the conductive sensor 320 is used for detecting the lower liquid level of the oil layer. Because the density of the floating ball is less than that of the grease, the floating ball device 310 can float on the grease layer, and the upper liquid level of the grease layer can be detected through the floating ball device 310; because the grease in the oil collecting box 200 contains a small amount of water, the water is at the bottom layer initially, the grease is at the upper layer, and the grease layer is firstly contacted with the conductive sensor 320 along with the rising of the grease liquid level in the oil collecting box 200, and at the moment, the conductive sensor 320 is not conductive. However, the height of the liquid level in the oil collecting box is smaller, and the floating ball device does not detect that the liquid in the oil collecting box reaches the preset liquid level, so that the thickness of the grease in the collecting box is judged to be not larger than the preset thickness. In this embodiment, the floating ball device 310 detects whether the liquid level in the oil collecting box 200 reaches a predetermined thickness, which is the highest liquid level thickness of the oil collecting box 200, and when the liquid level in the oil collecting box 200 is higher than the liquid level thickness, the liquid at the bottom of the oil collecting box 200 is drained through the second drainage pipe 600. As the liquid such as grease and the like continuously flows into the oil collecting box 300, the liquid level in the oil collecting box 300 continuously rises, the floating ball device 310 detects that the liquid level in the oil collecting box 300 reaches the preset liquid level, that is, the liquid level of the upper layer of the grease layer reaches the preset height, but at this time, the liquid level of the lower layer of the grease layer may be located above the conductive sensor 320, and the thickness of the grease in the oil collecting box 200 becomes thicker and thicker as more and more grease in the box 100 enters the oil collecting box 200. Due to the second drain pipe 600, the liquid level in the oil collecting box 200 reaches the preset height and cannot rise continuously, that is, the liquid level of the upper layer of the grease layer cannot rise, and the liquid level of the lower layer of the grease layer can move downwards. The lower level of the layer of grease reaches the conductive sensor 320, and the conductive sensor 320 is located in the grease, and the conductive sensor 320 detects that the liquid at its location is not conductive. That is, it means that the grease layer reaches a predetermined thickness by both the floating ball device 310 and the conductive sensor 320. In this way, when the floating ball device 310 detects that the liquid level of the liquid in the oil collecting box 320 is at the preset height and the conductive sensor 320 detects that the liquid is not conductive, the reminding device is started.
