Description

Technical Field

[0001] The present application relates to the field of catering wastewater treatment equipment, and more particularly to an integrated vacuum oil separator and pump station. Background Art

[0002] With the growth of population and the improvement of residents' living standards, my country's catering industry is also developing rapidly. What comes with it is the increase in the mountains of kitchen waste. To effectively treat the kitchen waste, the food residues can be separated and filtered from the oil and water. The food residues can be treated as fertilizer, and the filtered oil and water also need to be separated in time. The methods of separating oil and water include heating separation, centrifugal separation, static separation, etc., and static separation is usually used for the treatment of oily wastewater.

[0003] In the related art, the oil separation device includes an oil separator and a collecting tank. The lower end of the oil separator is connected to the collecting tank through a pipeline. When in use, the oily wastewater first enters the oil separator. At this time, the oil is in the upper layer and the water is in the lower layer. Then the water in the lower layer enters the collecting tank, thereby realizing oil-water separation.

[0004] Regarding the above-mentioned related technologies, there is a method of combining an oil separator and a collection tank to achieve oil-water separation. The equipment is large in size and occupies a lot of space. At the same time, a pump is required between the oil separator and the collection tank to achieve water transfer, which leads to the defect of high cost of the oil separation device. Summary of the invention

[0005] In order to make the oil separation equipment small in size, occupy less space and have low cost, the present application provides an integrated vacuum oil separator and pump station.

[0006] In the first aspect, the present application provides an integrated vacuum oil-tight tank, which adopts the following technical solution: An integrated vacuum oil-tight tank, comprising: A tank body is provided with a liquid storage cavity; A chamber partition, arranged in the liquid storage chamber, for dividing the chamber into an oil separation area and a wastewater discharge area; An oil-separating baffle is connected to a side of the chamber partition close to the oil-separating area, and a wastewater transfer chamber with an inlet facing downward is formed between the oil-separating baffle and the chamber partition; A transfer connecting piece, arranged on the chamber partition, the transfer connecting piece is connected to the wastewater transfer chamber, and the position of the transfer connecting piece is higher than the inlet of the wastewater transfer chamber; A vacuum tube has one end connected to the liquid storage chamber and the other end used to be connected to an external power source.

[0007] By adopting the above technical scheme, when working, the liquid storage chamber is first placed in a negative pressure state through a vacuum tube to allow the oil-containing wastewater to enter the oil separation area, and then the oil separation baffle will separate the oil in the upper layer and allow the wastewater in the lower layer to enter the wastewater transfer chamber from bottom to top, and then flow into the wastewater discharge area through the transfer connecting piece, thereby realizing oil-water separation. In summary, the wastewater discharge area and the oil separation area are combined in one tank body with the help of the oil separation baffle, and the wastewater can enter the wastewater discharge area by overflow, so there is no need to set up an additional pump to realize the transfer of wastewater, so that the equipment is small in size, occupies little space and has low cost. In addition, there is no need for a pump to send the oil-containing wastewater into the tank body, which can also avoid damage to the pump and reduce maintenance costs.

[0008] Preferably, there is a distance between the chamber partition and the upper inner wall of the liquid storage chamber.

[0009] By adopting the above technical solution, compared with the method of completely dividing the liquid storage chamber into two areas by a dividing partition, this design method can better maintain the pressure balance between the oil separation area and the wastewater discharge area when negative pressure treatment is performed through a vacuum tube, and subsequent wastewater can more smoothly enter the wastewater discharge area by overflow.

[0010] Preferably, the vacuum tube is rotatably arranged, the vacuum tube penetrates into the oil separation area from bottom to top, and the vacuum tube is provided with a stirring blade at a position lower than the inlet of the wastewater transfer chamber.

[0011] By adopting the above technical solution, the oily wastewater will be divided into three layers in the oil separation area, namely oil, water and mud from top to bottom. Therefore, by slowly rotating the vacuum tube and letting the stirring blades slowly stir the mud in the lower layer, it is possible to prevent the mud in the lower layer from solidifying, thereby facilitating the subsequent direct extraction of the oil and mud.

[0012] Preferably, an oil-water inlet is provided on the upper side of the tank body, the oil-water inlet is connected with the oil separation area, and the oil-water inlet is close to the vertical side wall of the liquid storage chamber; a drainage baffle is provided on the inner wall of the liquid storage chamber, and a splash-proof cavity is formed between the drainage baffle and the inner wall of the liquid storage chamber, the splash-proof cavity is tubular, and the splash-proof cavity is coaxially connected with the oil-water inlet.

[0013] By adopting the above technical solution, the oily wastewater enters the oil separation area vertically and enters the splash-proof cavity, which can avoid splashing or impact that causes the precipitated stratified liquid to shake, so the oily wastewater can be mixed more smoothly with the stratified liquid in the tank body to achieve a better separation effect.

[0014] Preferably, a drainage float and a warning float are provided in the wastewater discharge area, the warning float is located above the drainage float, and the warning float is located below the transfer connecting piece.

[0015] By adopting the above technical solution, when the wastewater level reaches the position of the drainage float, drainage work can be carried out, and when the wastewater level reaches the position of the warning float, drainage work will be forced to be carried out, and an alarm will be sounded to remind the management personnel that maintenance is required.

[0016] Preferably, a water-blocking baffle is provided on one side of the chamber partition close to the wastewater drainage area, and a wastewater transfer chamber with an outlet facing downward is formed between the water-blocking baffle and the chamber partition.

[0017] By adopting the above technical solution, due to the setting of the water-blocking baffle, when wastewater enters the wastewater discharge area, the water flows downward, so the wastewater is prevented from impacting the drainage float or the warning float, thereby preventing the drainage work from being started by mistake.

[0018] Preferably, the transfer connecting piece is a through hole arranged on the chamber partition.

[0019] By adopting the above technical solution, the communication between the wastewater transfer chamber and the wastewater discharge area can be achieved through a simple structure.

[0020] Preferably, the transfer connecting member includes a working turntable and a rotating driving member, the working turntable is rotatably installed on the chamber partition, the working turntable is non-coaxially provided with a liquid transfer hole, and the rotating driving member is drivingly connected to the working turntable.

[0021] By adopting the above technical solution, during the working process, the mud in the lower layer will gradually accumulate and the oil in the upper layer will gradually accumulate, so the liquid level of the wastewater will continue to change. Therefore, the overflow height can be changed by rotating the working turntable, so as to fully transfer more wastewater to the wastewater discharge area.

[0022] Preferably, the transfer connecting member includes a mounting base, a working slide and a sliding drive member, the mounting base is penetrated on the dividing chamber partition, the mounting base is provided with a mounting cavity, the mounting cavity is provided with a main through hole, the main through hole is extended in the vertical direction, and the main through hole is connected with the oil separation area or the wastewater discharge area; the working slide is vertically slidably arranged in the mounting cavity, the working slide cuts off the connection between the main through hole and the mounting cavity, the working slide is provided with a liquid transfer hole connected with the main through hole, and a plurality of the working slides are distributed in the horizontal direction; the sliding drive member is built into the mounting base, and the sliding drive member is connected with the working slide.

[0023] By adopting the above technical solution, the thickness of the mud in the lower layer is different at different locations, so the thickness of the water in the middle is also different. Therefore, different working slides can be placed at different heights through sliding driving parts, so the overflow heights at different locations can be changed according to the thickness of the water at different locations, so that the wastewater can be more fully transferred to the wastewater discharge area.

[0024] In a second aspect, the present application provides a pump station, which adopts the following technical solution: A pump station includes an integrated vacuum oil-trap tank, a bracket, a vacuum pump and a sewage pump. The bracket is used for installing the vacuum oil-trap tank, the vacuum pump is connected to the vacuum pipe, and the sewage pump is connected to the oil-trap area and the wastewater discharge area.

[0025] By adopting the above technical solution, the vacuum pump realizes negative pressure on the tank body so that oil and water can flow into the tank body, and the sewage pump is used to discharge sewage or a mixture of oil and sludge.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. During operation, the liquid storage chamber is first placed in a negative pressure state through a vacuum tube, 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 chamber from bottom to top, and then flows into the wastewater discharge area through the transfer connecting piece, thereby achieving oil-water separation. In summary, the wastewater discharge area and the oil separation area are combined and arranged in a tank body with the help of the oil separation baffle, and the wastewater can enter the wastewater discharge area by overflow, so there is no need to set up an additional pump to transfer the wastewater, so that the equipment is small in size, occupies less space and has low cost. In addition, there is no need for a pump to send the oily wastewater into the tank body, which can also avoid damage to the pump and reduce maintenance costs; 2. The oily wastewater enters the oil separation area vertically and enters the splash-proof chamber, which can avoid splashing or impact that causes the precipitated stratified liquid to shake, so the oily wastewater can be mixed with the stratified liquid in the tank more smoothly to achieve a better separation effect; 3. Due to the setting of the water-blocking baffle, when the wastewater enters the wastewater discharge area, the water flows downward, so the wastewater is prevented from impacting the drainage float or the warning float, thereby preventing the drainage work from being started by mistake.

[0036] The following is combined with Figure 1-8 This application is described in further detail.

[0037] The embodiment of the present application discloses an integrated vacuum oil-tight tank.

[0038] Example 1 Reference Figure 1 and Figure 2The integrated vacuum oil-tight tank includes a tank body 1, a chamber partition 2, an oil-isolating baffle 3, a transfer connecting piece 4 and a vacuum tube 5. The tank body 1 has a liquid storage chamber 11; the chamber partition 2 is arranged in the liquid storage chamber 11 to divide the liquid storage chamber 11 into an oil-isolating area 21 and a wastewater discharge area 22; the oil-isolating baffle 3 is connected to the side of the chamber partition 2 close to the oil-isolating area 21, and a wastewater transfer chamber 31 is formed between the oil-isolating baffle 3 and the chamber partition 2, and the inlet of the wastewater transfer chamber 31 faces downward, that is, water needs to enter the wastewater transfer chamber 31 from bottom to top; the transfer connecting piece 4 is a through hole arranged on the chamber partition 2, the transfer connecting piece 4 is connected to the wastewater transfer chamber 31, and the position of the transfer connecting piece 4 is higher than the inlet of the wastewater transfer chamber 31; one end of the vacuum tube 5 is connected to the liquid storage chamber 11, and the other end is connected to an external power source, so that the liquid storage chamber 11 can be in a negative pressure state.

[0039] Reference Figure 1 and Figure 2 The working process is as follows: first, the liquid storage chamber 11 is placed in a negative pressure state through the vacuum tube 5 to allow the oily wastewater to enter 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 chamber 31 from bottom to top; then the wastewater flows into the wastewater discharge area 22 through the transfer connecting piece 4, thereby achieving oil-water separation. In summary, the wastewater discharge area 22 and the oil separation area 21 are combined in one tank body 1 through the oil separation baffle 3; at the same time, the wastewater enters the wastewater discharge area 22 by overflow, so there is no need to set up a pump to achieve this, thereby having a small size, small footprint and low cost; in addition, because there is no need for a pump to deliver the oily wastewater into the tank body 1, damage to the pump can be avoided and maintenance costs can be reduced.

[0040] Reference Figure 1 and Figure 2 Considering that the wastewater is transferred from the oil-separating area 21 to the wastewater discharge area 22 by overflow, and the present application allows the oily wastewater to enter the tank body 1 by placing the tank body 1 under negative pressure, in order to allow the wastewater to flow smoothly from the oil-separating area 21 into the wastewater discharge area 22, the dividing partition 2 will not completely separate the liquid storage chamber 11 into two unconnected areas, but will partially separate them. Specifically, the dividing partition 2 and the upper inner wall and distance of the liquid storage chamber 11, so when negative pressure treatment is performed through the vacuum tube 5, the pressure between the oil-separating area 21 and the wastewater discharge area 22 can be better balanced, and subsequent wastewater can flow more smoothly into the wastewater discharge area 22 by overflow.

[0041] Reference Figure 1 and Figure 2In order to prevent the oily wastewater from entering the oil separation area 21 and greatly stirring the already settled stratified liquid, the following settings are correspondingly arranged: an oil-water inlet 12 is arranged on the upper side of the oil tank, and the oil-water inlet 12 is connected to the oil separation area 21, and the oil-water inlet 12 is close to the vertical side wall of the liquid storage chamber 11. At the same time, a drainage baffle 6 is arranged on the inner wall of the liquid storage chamber 11, and a splash-proof cavity 61 is formed between the drainage baffle 6 and the inner wall of the liquid storage chamber 11. The splash-proof cavity 61 is tubular, and the splash-proof cavity 61 is coaxially connected to the oil-water inlet 12. The oily wastewater will vertically enter the oil separation area 21 and also enter the splash-proof cavity 61, so that splashing or impact that causes the settled stratified liquid to shake can be avoided, so that the oily wastewater can be mixed with the stratified liquid in the tank body 1 more smoothly, thereby achieving a better separation effect.

[0042] Reference Figure 1 and Figure 2 In this embodiment, a drainage float 221 and a warning float 222 are also provided in the wastewater drainage area, wherein the warning float 222 is located above the drainage float 221, but the warning float 222 is located below the transfer connecting piece 4. When the water level of the wastewater reaches the position of the drainage float 221, the drainage work can be started, and when the water level of the wastewater reaches the position of the warning float 222, the drainage work will be forced to be carried out, and an alarm will be sounded to remind the management personnel that maintenance is required.

[0043] Reference Figure 1 and Figure 2 In order to prevent the wastewater from directly impacting the drainage float 221 and the warning float 222 when entering the wastewater discharge area 22, and mistakenly starting the drainage work, a water-proof baffle 7 is provided near the wastewater drainage area of ​​the chamber partition 2, and a wastewater transfer chamber 71 with an outlet facing downward is formed between the water-proof baffle 7 and the chamber partition 2. When the wastewater enters the wastewater discharge area 22, the water flows downward, so the wastewater is prevented from impacting the drainage float 221 or the warning float 222, thereby preventing the drainage work from being mistakenly started.

[0044] The implementation principle of an integrated vacuum oil-water separator in an embodiment of the present application is as follows: when working, the liquid storage chamber 11 is first placed in a negative pressure state through the vacuum tube 5 to allow the oil-containing wastewater to enter the oil-water separator area 21, and then the oil-water separator baffle 3 separates the oil in the upper layer and allows the wastewater in the lower layer to enter the wastewater transfer chamber 31 from bottom to top, and then flows into the wastewater discharge area 22 through the transfer connecting piece 4, thereby realizing oil-water separation. In summary, the wastewater discharge area 22 and the oil-water separator area 21 are combined and arranged in one tank body 1 with the help of the oil-water separator baffle 3, and the wastewater can enter the wastewater discharge area 22 by overflow, so there is no need to set up an additional pump to realize the transfer of wastewater, so that the equipment is small in size, occupies little space and has low cost. In addition, there is no need for a pump to send the oil-containing wastewater into the tank body 1, which can also avoid damage to the pump and reduce maintenance costs.

[0045] Example 2 Reference Figure 3 , which is different from Example 1 in that: the transfer connecting member 4 includes a working turntable 41 and a rotating driving member, the working turntable 41 is rotatably penetrated on the chamber partition 2, the working turntable 41 is non-coaxially provided with a liquid transfer hole 8, and the rotating driving member is connected to the working turntable 41. During the working process, the mud in the lower layer will gradually accumulate, and the oil in the upper layer will also gradually accumulate, so the liquid level of the wastewater will also change continuously. At this time, the overflow height can be changed by rotating the working turntable 41, so as to fully transfer more wastewater to the wastewater discharge area 22.

[0046] Example 3 Reference Figure 4 , which is different from Example 1 in that: the transfer connecting member 4 includes a mounting base 42, a working slide 43 and a sliding drive member, the mounting base 42 is penetrated on the dividing chamber partition 2, the mounting base 42 is provided with a mounting cavity 421, the mounting cavity 421 is provided with a total through hole 422, one mounting cavity 421 has two total through holes 422, one total through hole 422 is connected to the oil separation area 21, and the other is connected to the wastewater discharge area 22, and multiple mounting cavities 421 are distributed in the horizontal direction; the working slide 43 is vertically slidably arranged in the mounting cavity 421, one working slide 43 corresponds to one mounting cavity 421, the working slide 43 will completely cut off the connection between the total through hole 422 and the mounting cavity 421, and the working slide 43 is provided with a liquid transfer hole 8 connected to the total through hole 422; the sliding drive member is built into the mounting base 42, the sliding drive member is connected to the working slide 43, and the sliding drive member is used to drive the working slide 43 to move up and down.

[0047] Reference Figure 4 During the working process, since the thickness of the lower layer is different at different positions, the thickness of the water in the middle is also different. Therefore, the different working slides 43 can be placed at different heights through the sliding drive parts. Therefore, the overflow heights at different positions can be changed according to the thickness of the water at different positions, so that the wastewater can be more fully transferred to the wastewater discharge area 22.

[0048] Example 4 Reference Figure 5 The difference from Example 1 is that, in order to prevent the mud in the lower layer from solidifying, the vacuum tube 5 penetrates into the liquid storage chamber 11 from bottom to top, and the vacuum tube 5 is provided with a stirring blade 51 at a position lower than the entrance of the wastewater transfer chamber 31. During the working process, the vacuum tube 5 can be rotated slowly to prevent the mud from solidifying, thereby facilitating the subsequent direct extraction of the oil and mud.

[0049] The embodiment of the present application also discloses a pump station.

[0050] Reference Figure 6The pump station includes the integrated vacuum oil-water separator, bracket 9, vacuum pump 91 and sewage pump 92 in the aforementioned embodiment. The overall shape of the oil-water separator is cylindrical. The bracket 9 is provided for the installation of the vacuum oil-water separator. The vacuum pump 91 is connected to the vacuum pipe 5. The sewage pump 92 is connected to the oil-water separator area 21 and the wastewater discharge area 22. In the embodiment of the present application, the oil-water separator is vertically arranged, and a vacuum pump 91 is provided. The vacuum pump 91 is horizontally arranged below the oil-water separator, so the vacuum pipe 5 penetrates into the oil-water separator from bottom to top. There is a sewage pump 92, and the sewage pump 92 is vertically arranged on the side of the oil-water separator.

Secondly, the vacuum pump 91 may be horizontally arranged below the oil separator, and the sewage pump 92 may be vertically arranged on the side of the oil separator, and multiple vacuum pumps 91 and sewage pumps 92 may be arranged.
