[0001] The present application relates to the field of catering wastewater treatment equipment, in particular to an integrated vacuum oil separation tank and pump station. BACKGROUND

[0002] With the growth of population and the improvement of residents' living standards, the catering industry in China is also developing rapidly, which leads to the increase of kitchen waste accumulation. Effective treatment of kitchen waste can be achieved by separating and filtering food residues and oil-water. Food residues can be treated as fertilizer, and filtered oil-water also needs to be separated in time. The separation methods of oil-water include heating separation, centrifugal separation and static separation. For the treatment of oil-containing wastewater, static separation is usually used.

[0003] In related technologies, the oil separation device includes an oil separation tank and a collection tank. The lower end of the oil separation tank is connected to the collection tank through a pipeline. During use, oil-containing wastewater first enters the oil separation tank, at which time the oil is on the upper layer and the water is on the lower layer. Then the water on the lower layer enters the collection tank, thereby realizing oil-water separation.

[0004] For the related technologies in the above, the oil-water separation is realized by combining the oil separation tank with the collection tank, which has the defects of large equipment volume, large occupation area, and the need to set a pump between the oil separation tank and the collection tank to realize water transfer, thereby leading to high cost of the oil separation device.

[0013] By adopting the technical scheme, in working, the liquid storage cavity is in a negative pressure state through the vacuum pipe, so that the oily wastewater enters the oil separation area, then the oil separation baffle separates the oil in the upper layer and allows the wastewater in the lower layer to enter the wastewater transfer cavity from bottom to top, and then flows into the wastewater discharge area through the transfer communication piece, so that the oil-water separation is realized. In summary, the oil separation baffle is used to combine the wastewater discharge area and the oil separation area in one tank body, and the wastewater can enter the wastewater discharge area by overflow, so that an additional pump is not needed to realize the transfer of the wastewater, thereby the device is small in size, occupies less space and is low in cost, and in addition, a pump is not needed to send the oily wastewater into the tank body, and the damage of the pump can be avoided to reduce the maintenance cost.

[0014] Preferably, the cavity separation baffle is spaced apart from the upper inner wall of the liquid storage cavity.

[0015] By adopting the technical scheme, compared with the way that the cavity separation baffle completely separates the liquid storage cavity into two regions, in the negative pressure treatment through the vacuum pipe, the pressure between the oil separation area and the wastewater discharge area can be better balanced, and the subsequent wastewater can flow more smoothly into the wastewater discharge area by overflow.

[0017] By adopting the technical scheme, the oily wastewater is divided into three layers in the oil separation area from top to bottom, namely oil, water and mud, so that the vacuum pipe is slowly rotated and the stirring blades slowly stir the mud in the lower layer, so that the solidification of the mud in the lower layer can be prevented, thereby facilitating the subsequent direct removal of the oil and mud.

[0022] Preferably, the side of the sub-cavity partition plate close to the wastewater drainage area is provided with a waterproof baffle, and a wastewater transfer-in cavity with downward outlet is formed between the waterproof baffle and the sub-cavity partition plate.

[0023] By adopting the above technical scheme, because the waterproof baffle is arranged, when the wastewater enters the wastewater drainage area, the water flows downward, so that the wastewater is prevented from impacting the drainage floating ball or the warning floating ball, thereby preventing the drainage work from being started by mistake.

[0029] By adopting the technical scheme, the mud in the lower layer is different in thickness at different positions, so the thickness of the water in the middle is also different, and therefore the different working slides can be placed at different heights by the sliding driving member, so the overflow height at different positions can be changed according to the thickness of the water at different positions, and thus the waste water can be more fully transferred to the waste water discharge area.

[0030] In a second aspect, the application provides a pump station, which adopts the following technical scheme:

[0033] In summary, the application has at least one of the following beneficial technical effects:

[0034] 1. In operation, the liquid storage cavity is first placed in a negative pressure state through the vacuum pipe, so that the oil-containing waste water enters the oil separation area, then the oil separation baffle separates the oil in the upper layer and allows the waste water in the lower layer to enter the waste water transfer cavity from bottom to top, and then flows into the waste water discharge area through the transfer communication member, so as to realize oil-water separation. In summary, the waste water discharge area and the oil separation area are combined and arranged in one tank body by means of the oil separation baffle, and the waste water can enter the waste water discharge area by overflow, so that an additional pump is not needed to realize the transfer of waste water, thereby the device is small in size, occupies less space and is low in cost.

[0036] 3.

DETAILED DESCRIPTION

[0046] The following will be described in detail with reference to the accompanying drawings. Figures 1-8 The present application will be further described in detail.

[0047] The present application discloses an integrated vacuum oil separation tank.

[0048] Embodiment 1

[0049] Reference will be made to Figure 1 and Figure 2The integrated vacuum oil separation tank comprises a tank body 1, a cavity separation plate 2, an oil separation baffle 3, a transfer communication piece 4 and a vacuum pipe 5. The tank body 1 has a liquid storage cavity 11. The cavity separation plate 2 is arranged in the liquid storage cavity 11 to divide the liquid storage cavity 11 into an oil separation area 21 and a wastewater discharge area 22. The oil separation baffle 3 is connected to one side of the cavity separation plate 2 close to the oil separation area 21. An wastewater transfer cavity 31 is formed between the oil separation baffle 3 and the cavity separation plate 2. The inlet of the wastewater transfer cavity 31 faces downward, that is, water needs to enter the wastewater transfer cavity 31 from bottom to top. The transfer communication piece 4 is a through hole arranged on the cavity separation plate 2. The transfer communication piece 4 is in communication with the wastewater transfer cavity 31. The position of the transfer communication piece 4 is higher than the inlet of the wastewater transfer cavity 31. One end of the vacuum pipe 5 is in communication with the liquid storage cavity 11, and the other end is in communication with an external power source, so that the liquid storage cavity 11 can be in a negative pressure state.

[0050] With reference to Figure 1 and Figure 2 , the working process is as follows. First, the liquid storage cavity 11 is in a negative pressure state through the vacuum pipe 5, so that the oil-containing wastewater enters the oil separation area 21. Then, the oil separation baffle 3 separates the oil in the upper layer and allows the wastewater in the lower layer to enter the wastewater transfer cavity 31 from bottom to top. Then, the wastewater flows into the wastewater discharge area 22 through the transfer communication piece 4, so that oil-water separation can be realized. In summary, the oil separation baffle 3 is used to combine the wastewater discharge area 22 and the oil separation area 21 in one tank body 1. The wastewater enters the wastewater discharge area 22 by overflow, so a pump is not needed, thereby reducing the volume, saving the land occupation and lowering the cost. In addition, since the pump is not needed to send the oil-containing wastewater into the tank body 1, the damage of the pump can be avoided, thereby reducing the maintenance cost.

[0051] With reference to Figure 1 and Figure 2 , considering that the wastewater is transferred from the oil separation area 21 to the wastewater discharge area 22 by overflow, and the oil-containing wastewater enters the tank body 1 by allowing the tank body 1 to be in a negative pressure state, in order to make the wastewater flow smoothly from the oil separation area 21 to the wastewater discharge area 22, the cavity separation plate 2 does not completely separate the liquid storage cavity 11 into two regions that are not in communication with each other, but partially separates the liquid storage cavity 11. Specifically, the cavity separation plate 2 is spaced apart from the upper inner wall of the liquid storage cavity 11. Therefore, when the negative pressure treatment is performed through the vacuum pipe 5, the pressure between the oil separation area 21 and the wastewater discharge area 22 can be better balanced, and the subsequent wastewater can flow more smoothly into the wastewater discharge area 22 by overflow.

[0052] With reference to Figure 1 and Figure 2In order to prevent the oil-containing wastewater from entering the oil separation area 21 and greatly stirring the already precipitated layered liquid, the following is provided: the upper side of the oil tank is provided with an oil-water inlet 12, the oil-water inlet 12 is in communication with the oil separation area 21, the oil-water inlet 12 is close to the vertical side wall of the liquid storage cavity 11, meanwhile, the inner wall of the liquid storage cavity 11 is provided with a drainage baffle 6, the drainage baffle 6 and the inner wall of the liquid storage cavity 11 form a splash-proof cavity 61, the splash-proof cavity 61 is tubular, the splash-proof cavity 61 is coaxially communicated with the oil-water inlet 12, then the oil-containing wastewater will enter the oil separation area 21 vertically and also enter the splash-proof cavity 61, so that splashing or impact to make the precipitated layered liquid shake can be avoided, so that the oil-containing wastewater can be more gently mixed with the layered liquid in the tank body 1, and a better separation effect can be achieved.

[0053] With reference to Figure 1 and Figure 2 In the embodiment, the wastewater drainage area is further provided with a drainage float ball 221 and an alarm float ball 222, wherein the alarm float ball 222 is located above the drainage float ball 221, but the alarm float ball 222 is located below the transfer communication piece 4, when the water level of the wastewater reaches the position of the drainage float ball 221, the drainage work can be started, when the water level of the wastewater reaches the position of the alarm float ball 222, the drainage work is forced to be carried out, and the management personnel is prompted to overhaul.

[0054] With reference to Figure 1 and Figure 2 In order to prevent the wastewater from directly impacting the drainage float ball 221 and the alarm float ball 222 when entering the wastewater drainage area 22, and misstarting the drainage work, the water-blocking baffle 7 is arranged close to the wastewater drainage area of the cavity separation plate 2, the water-blocking baffle 7 and the cavity separation plate 2 form a wastewater transfer-in cavity 71 with the outlet downward, when the wastewater enters the wastewater drainage area 22, the water flows downward, so that the wastewater is prevented from impacting the drainage float ball 221 or the alarm float ball 222, thereby the misstarting of the drainage work can be prevented.

[0055] The implementation principle of the integrated vacuum oil separation tank in the embodiment is as follows: in the working process, the liquid storage cavity 11 is first in a negative pressure state through the vacuum pipe 5, so that the oil-containing wastewater enters the oil separation area 21, then the oil separation baffle 3 separates the oil in the upper layer and makes the wastewater in the lower layer enter the wastewater transfer-out cavity 31 from bottom to top, and then flows into the wastewater drainage area 22 through the transfer communication piece 4, so that the oil-water separation is realized, in summary, the wastewater drainage area 22 and the oil separation area 21 are combined and arranged in the tank body 1 by means of the oil separation baffle 3, and the wastewater can enter the wastewater drainage area 22 in the form of overflow, so that an additional pump is not needed to realize the transfer of the wastewater, thereby the equipment is small in size, occupies less land, and is low in cost, in addition, a pump is not needed to send the oil-containing wastewater into the tank body 1, and the damage of the pump can be avoided, thereby the maintenance cost is reduced.
