Detailed Description

FIG. 1 is a schematic illustration of a water oil separation system according to one embodiment of the present application. An oil-water separation system comprising: a residue removing apparatus 100 for removing solid residues in the mixed liquid introduced into the oil-water separation system; and the oil-water separation equipment 200 is connected with the deslagging equipment 100 and is used for carrying out oil-water separation on the liquid filtered by the deslagging equipment 100. Wherein, slag removal equipment 100 includes: a diversion bin 110, a sewage collecting device 120 and a slag collecting bin 140. One end of the diversion bin 110 is provided with a liquid inlet 111, the liquid inlet 111 is connected with the oil-water separation equipment 200 and is used for guiding liquid into the oil-water separation equipment 200, the other end of the diversion bin is provided with a slag discharge port 112, and the slag discharge port 112 is connected with the slag collection bin 140.

The dirt collecting device 120 is rotatably disposed in the diversion bin 110 for collecting solid residue in the mixed liquid, and the first end surface 1201 of the dirt collecting device 120 is disposed above the residue collecting bin 140 for dumping the solid residue in the dirt collecting device 120 into the residue collecting bin 140.

The dirt collecting device 120 is an inverted cone-shaped bucket-shaped container, and the bottom surface 1203 of the dirt collecting device 120 is an inclined surface.

As described in the background, in the oil-water separation system, the design of the dirt collecting device is particularly important. Wherein, dirty device of collection is used for collecting the solid residue in the mixed liquid to be used for empting the solid residue to in receiving the sediment storehouse. If the sewage collecting device is not properly designed, the residue in the residual bottom of the pot cannot be effectively deposited, thereby still causing the blockage of the sewer pipe and even the drainage pipe. Therefore, how to design a dirt collecting device capable of effectively depositing the residue in the residual pan bottom becomes a problem to be solved by the current container.

Based on this, referring to fig. 2A to 2D, the applicant proposes a sewage collecting device 120 for use in an oil-water separation system. Referring to fig. 1, the sewage collecting device 120 is used for collecting solid residues in the mixed liquid and pouring the solid residues into the residue collecting bin by rotating to a position 120'.

In order to effectively deposit the residue in the residual pan bottom, the dirt collecting device 120 is configured as a hopper-shaped container with an inverted cone shape, as shown in fig. 2A to 2D. And the bottom surface 1203 of the dirt collection device 120 is a sloped surface. Thus, with this configuration, the residue in the bottom of the pan can be effectively deposited on the bottom of the dirt collecting device 120 (e.g., the vertex 1207), so that the residue in the remaining bottom of the pan can be prevented from entering the subsequent oil-water separation device 200.

Alternatively, referring to fig. 2A, a second end surface 1202 of the dirt collection device 120 opposite to the first end surface 1201, a bottom surface 1203 of the dirt collection device 120, and side surfaces 1204, 1205 of the dirt collection device 120 are all triangular. And the second end face 1202, the bottom face 1203 and the side faces 1204, 1205 have the same vertex 1207.

Referring to fig. 2A, the second end 1202, the bottom 1203 and the sides 1204, 1205 of the dirt collection device 120 have the same apex 1207. Therefore, the bottom surface 1203 and the side surfaces 1204 and 1205 of the dirt collecting device 120 are all inclined inwards, so that the structure is more favorable for depositing the residues in the bottom of the pan, and the residues in the residual bottom of the pan can be effectively deposited on the dirt collecting device 120.

Alternatively, as shown with reference to fig. 2B, the bottom surface 1203 of the dirt collecting device 120 is disposed to be inclined downward in a direction from the bottom of the first end surface 1201 to the bottom of the second end surface 1202. This configuration further facilitates the sliding of residue falling onto the bottom surface 1203 down to the apex 1207, thereby allowing the residue in the remaining pan bottom to be effectively deposited on the dirt collection device 120.

Alternatively, as shown with reference to fig. 2A, 2C, and 2D, the bottom surface 1203 of the dirt collecting device 120 is disposed to be inclined downward in a direction from the bottom of the first end surface 1201 to the bottom of the second end surface 1202. This configuration further facilitates the sliding of debris falling onto sides 1204 and 1205 down to apex 1207, thereby allowing debris from the remaining bottom of the pan to be effectively deposited on the collection device 120.

Optionally, the oil-water separation system further comprises a frame structure 400 disposed outside the deslagging apparatus 100 and the oil-water separation apparatus 200. Wherein, the dirt collecting device 120 is disposed inside the diversion bin 110, and the first end surface 1201 of the dirt collecting device 120 is connected with the frame structure 400 through the connecting shaft 122.

Therefore, the first end surface 121 of the slag collecting device 120 is connected with the frame structure 400 through the connecting shaft 122, when the amount of the residue in the slag collecting device 120 reaches a certain amount, the slag collecting device 120 rotates around the connecting shaft 122 to reach the position of the slag collecting device 120', so that the residue in the slag collecting device 120 enters the slag collecting barrel 141 which is arranged in the slag collecting bin 140 in advance through the slag discharging port 112. Through the mode, the filtered residues are not poured by people, so that the residues are more simply and quickly cleaned.

Filtered residues enter the residue collecting channel 141, so that uniform replacement is facilitated.

Preferably, the filtering apparatus 100 further comprises: and a filtering device 130, wherein the filtering device 130 is arranged at the liquid inlet 111 and is used for further filtering the residue in the liquid.

Specifically, the mixture in the pod 110 is heated by the heating plate 113. Because there is often already solidified oil in the mix, such as tallow in the remaining liquid mix of a chafing dish, and easily solidified sheeting. If the oil is not heated, the hardened oil will block the slag collecting device 120 and the filtering device 130, so that the slag collecting device 120 cannot filter. The solid oil in the mixture is melted by the heating plate 113, so that the slag collecting device 120 is not blocked, and the filtering efficiency is increased.

Preferably, the slag collection bin 140 is provided with a first bin door (not shown) for replacing the slag collection bucket 141. The design of the first bin door is convenient for replacing the slag collecting barrel 141, and simultaneously, the sealing environment of the slag collecting bin 140 is ensured, so that the slag collecting bin is safer and more sanitary. The slag collecting bin 140 may be of a drawer type design, so that the replacement of the slag collecting barrel 141 is more labor-saving and convenient.

Preferably, the oil-water separator further comprises a control device 300, wherein the control device 300 is connected with an oil-water sensor 240 pre-selected and arranged inside the oil-water separator 200; the oil water sensor 240 is used to measure the type of the medium fixed in position within the oil water separating device 200 and transmit the measurement result to the control device 300; the control device 300 controls the oil-water separation device 200 to discharge oil or water based on the measurement result.

Specifically, an oil-water sensor 240 is provided inside the oil-water separating device 200, and the oil-water sensor 240 determines whether the medium is oil or water by measuring the dielectric constant of the liquid medium. Because the oil water sensor 240 is located at a fixed location within the oil water separator device 200, the result measured by the oil water sensor 240 is the type of media at that fixed location. For example, the result of the measurement may be that the medium at the fixed location is water. The oil-water sensor 240 is connected to the control device 300, and the oil-water sensor 240 transmits the measured result to the control device 300. The control device 300 controls the oil-water separation system 200 to discharge oil or water based on the measurement result of the oil-water sensor 240. For example, if the result measured by the oil-water sensor 240 is water, it indicates that the fixed position of the oil-water separation device 200 has water, and the control device 300 controls the oil-water separation device 200 to discharge water; if the oil-water sensor 240 measures oil, the control device 300 controls the oil-water separation device 200 to discharge oil.

In the prior art, an oil-water separation system cannot monitor liquid discharged after separation, so that the effect of oil-water separation cannot be effectively guaranteed. In this way, oil discharge or drainage is controlled according to the measurement result of the oil-water sensor 240, so that accurate active drainage and oil discharge are realized, and the oil collection purity is ensured. The technical problem is solved, and the monitoring of the oil-water separation effect is realized.

Specifically, since the oil-water separation device 200 is internally filled with oil-water mixed liquid, if the temperature is too low, the oil in the oil-water separation device 200 may be solidified, so that the oil and water are mixed together, which may affect the accuracy of the measurement result of the oil-water sensor 240. In this embodiment, the control device 300 starts the oil-water sensor only when the temperature reaches the threshold value. Through the linkage of the temperature sensor 230 and the oil-water sensor 240, the accuracy of the measurement result of the oil-water sensor 240 is ensured, and the purity of the oil or water discharged from the oil-water separation device 200 is further ensured.

The technical problem is solved, and the detection of the oil-water separation effect is realized.

Preferably, the oil-water separating apparatus 200 further includes: an oil-water separation bin 210; the oil drain port 212 is disposed on a side surface of the oil-water separation bin 210; the water outlet 211 is disposed at the bottom of the oil-water separation bin 210; the temperature sensor 230 and the oil-water sensor 240 are disposed inside the oil-water separation chamber 210, and the oil-water sensor 240 is disposed below the oil drain port 212.

Specifically, in this embodiment, the solid residue in the mixed liquid is filtered out by the filtering device 100, so that the oil-water mixed liquid enters the oil-water separating device 200, and the oil-water separating bin 210 in the oil-water separating device 200 performs oil-water separation by using the difference in density of oil and water.

Further, a drain port 211 is provided at the bottom of the oil-water separation chamber 210, and an oil drain port 212 is provided at the upper portion of the oil-water separation chamber 210. The water separated from the oil is discharged through the drain port 211, and the oil is discharged through the drain port 212.

Specifically, a heat radiation lamp 220 is disposed in the oil-water separation chamber 210, and can heat the liquid in the oil-water separation chamber 210. Because the mixed liquid contains oil and water, the oil is easy to solidify at low temperature, which is not beneficial to oil-water separation, and the heat radiation lamp 200 can realize rapid heating, so that the hardened or solidified oil can be rapidly melted. The constant temperature heating plate 250 has the functions of heat preservation and heating, not only can keep warm to the oil-water separation bin 210, but also can play a role in further heating, and the constant temperature heating plate 250 is attached to the inner surface of the oil-water separation bin 210, so that the contact area with liquid is increased, the heating is more uniform, and the liquid in the oil-water separation bin 210 is further kept at a certain temperature, so that the oil is kept in a liquid state, and the oil-water separation is facilitated.

In this embodiment, the heat radiation lamp 220 is fixed to the top of the oil-water separation chamber 210, and the liquid inside the oil-water separation chamber 210 is heated by the heat radiation lamp. The heat radiation lamp 220 does not directly contact with the liquid, thereby solving the hidden trouble caused by immersion heating in the prior art. In addition, in the oil-water separation chamber 210, oil is the most heated portion, and since the oil has a lower density than water and is thus located at the upper portion of the oil-water separation chamber 210, the oil is heated by the top radiation lamp, and the oil is heated more efficiently.

Further, the constant temperature heating plate 250 plays a role in heat preservation and heating of the oil-water separation bin 210, and the internal temperature of the oil-water separation bin 210 is more effectively kept by adopting a dual heating mode, so that energy is saved.

In addition, the temperature sensor 230 measures the temperature of the liquid in the oil-water separation bin 210, and sends the measured temperature value to the control device 300, and when the measured temperature value is smaller than the lower limit temperature value, the constant temperature heating plate 250 is started to heat the liquid in the oil-water separation device 200. The temperature sensor 230 is controlled by the control device 300, so that the thermostatic heating plate 250 is activated only when the temperature of the liquid in the oil-water separation chamber 210 is lower than a preset value. When the temperature value measured by the temperature sensor 230 is greater than the upper limit temperature value, the control device 300 turns off the constant temperature heating plate 250. When the constant temperature heating plate is in failure or the equipment stops for a period of time and then starts, the temperature sensor 300 feeds back the set temperature, when the temperature exceeds the low limit value, the heat radiation and the like start to quickly heat the hardened grease, so that the hardened grease is quickly melted and then is smoothly discharged. Therefore, the power consumption of the heat radiation lamp can be saved, the temperature of the liquid in the oil-water separation bin 210 is kept within a certain range, and the oil-water separation effect is guaranteed.
