Description

Technical Field

[0001] The utility model relates to the technical field of oil separation, in particular to an automatic oil separation device with a cleaning structure. Background Art

[0002] The principle of the oil separator is based on the physical properties of oil-water separation. Through reasonable design and construction, liquids containing grease or fat can be separated and collected, which can effectively purify the liquid, prevent grease or fat from polluting the environment, and improve the reuse rate of the liquid.

[0003] At present, the imported screens and separation tanks on the market need to be cleaned manually regularly. The oil accumulated on the screens over a long period of time will block the screen holes and must be cleaned manually regularly. The large pieces of garbage filtered out are transported to the waste bin through the slag discharger. Due to the uncertainty of the incoming materials, the traditional slag remover is always running, which consumes electricity and causes unnecessary wear. The small particles at the bottom of the sedimentation separation tank will fill up the separation tank over time and have to be stopped for cleaning. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an automatic oil separator with a cleaning structure, which aims to completely save manual cleaning through self-cleaning technology, thereby eliminating the problem of equipment stopping production for cleaning.

[0005] The idea of ​​the utility model is: 1. hot water is used to clean the oil stains on the imported grid to make it melt and fall off; 2. the water flow drives the sediments on the bottom of the separation tank to collect them together and suck them out with a sewage pump; 3. the operation of the slag remover is triggered by material level detection, thereby reducing the power consumption and wear of the slag remover.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an automatic oil separator with a cleaning structure, including a separation tank, a feed cylinder connected to the left side of the top of the separation tank, a filter screen installed in the lower part of the feed cylinder, a nozzle installed above the filter screen in the feed cylinder and connected to a temperature-raising and pressurizing device, a water inlet pipe of the temperature-raising and pressurizing device connected to a sewage tank, a water inlet of the circulation pump connected to the middle of the outer wall of the separation tank for taking water, a water outlet of the circulation pump connected to several drive nozzles through a pipeline, an oil storage cylinder connected to the top of the separation tank, and a U-shaped pipeline connected to the sewage tank on the right side of the top of the separation tank. In the utility model, the driving system composed of the circulation pump, the circulation pipeline and the driving nozzle is started regularly or irregularly to drive the settled fine garbage to the sewage pump and the sewage pump is discharged regularly or irregularly to realize the self-cleaning function. In the utility model, the sewage is connected to the temperature-raising and pressurizing device, the hot water pipe and the hot water nozzle to form a grid hot washing system, which is started regularly or irregularly to wash the grid with hot water to achieve the cleaning purpose.

[0007] The utility model has the following beneficial effects:

[0008] In the utility model, after the primary sewage enters the separation tank through the grid mesh on the feed cylinder, the oil will float up after standing for a period of time, and the sewage will be driven by the driving system composed of a circulation pump, a circulation pipe and a driving nozzle at a regular or irregular time to drive the settled fine garbage to the primary sewage pump, and the primary sewage pump will discharge it through the outlet pipe at a regular or irregular time to achieve a self-cleaning function. The secondary sewage is discharged into the sewage pool through the U-shaped pipe. When the secondary sewage in the sewage pool rises to a certain height, it will be discharged through the outlet pipe by the secondary sewage pump. Then, the secondary sewage is connected to the grid hot washing system composed of a temperature-raising pressurizer, a hot water pipe and a hot water nozzle, which can be started regularly or periodically to perform hot water cleaning on the movable grid mesh and the fixed grid mesh to achieve the cleaning purpose. After detecting that too much large garbage is accumulated on the top of the movable grid mesh, the material level detector will issue an alarm to remind the staff to remove the movable grid mesh and the garbage above through the clamping plate for cleaning.

[0017] Reference Figure 1-4 The utility model provides an embodiment: an automatic oil separator with a cleaning structure, including a separation tank 1, a feed cylinder 5 is provided on the left side of the top of the separation tank 1, a connecting pipe 12 is fixedly connected to the bottom of the left end of the temperature increasing and pressurizing device 16, a sewage tank 2 is fixedly connected to the middle of the outer wall of the connecting pipe 12, an oil storage cylinder 11 is fixedly connected to the inner wall of the middle of the top of the circulating pump 3, a primary sewage pump is fixedly connected to the front of the left bottom end of the inner wall of the separation tank 1, a number of secondary sewage pumps are fixedly connected to the rear side of the inner wall of the bottom end of the sewage tank 2, the tops of the primary sewage pump and the secondary sewage pump are fixedly connected to water outlet pipes, the tops of the water outlet pipes respectively penetrate the outer walls of the separation tank 1 and the sewage tank 2 and extend to the outside, and the right side of the inner wall of the top of the separation tank 1 is connected to the left side of the inner wall of the top of the sewage tank 2 through a U-shaped pipe 8.

[0018] Specifically, the bottom of the U-bend of the U-shaped tube 8 is flush with the top of the oil storage cylinder 11, and the sewage at the bottom of the separation tank 1 is pumped into the sewage tank 2 by natural siphoning while maintaining the water level of the separation tank. The heating and pressurizing device 7 can heat the sewage entering the heating and pressurizing device 7 through the connecting pipe 12, and the first-stage sewage pump can discharge the internal sewage through the outlet pipe. An oil extraction port is provided on the side of the oil storage cylinder 11 for taking out the floating oil.

[0019] Specifically, the hot water nozzle 9 can be fixed by a bracket directly above or above the filter screen 6. In principle, the hot water can be sprayed onto the filter screen 6 to achieve the purpose.

[0020] Specifically, what type of slag remover is used to remove the coarse slag after filtration, such as chain plate, spiral, vacuum, etc., is not within the scope of discussion of this case.

[0021] The water inlet of the circulation pump 3 is connected to the middle of the separation tank 1, and the water outlet of the circulation pump 3 is connected to the circulation pipe 4. The water outlet of the circulation pump 3 is connected to the driving component through the circulation pipe 4. The driving component includes a plurality of driving nozzles 13. The driving nozzles 13 are distributed at the bottom of the separation tank 1 and use water flow to drive the sediment to the first-level sewage pump for discharge. The circulation pipe 4 is not limited to the inside and outside of the separation tank 1, and the driving effect can be achieved.

[0022] Specifically, the driving system composed of the circulation pump 3, the circulation pipe 4 and the driving nozzle 13 is started regularly or irregularly to drive the settled fine garbage to the primary sewage pump for sewage discharge, thereby realizing the self-cleaning function.

[0023] Working principle: First, primary sewage flows in through the feed barrel 5, and large pieces of garbage are filtered out by the filter grid 6. Small pieces of garbage enter the separation tank 1 with the sewage. Due to the different specific gravities of oil and water, the oil floats on the upper part of the liquid surface and eventually enters the oil storage cylinder 11 for regular recovery. As large pieces of garbage accumulate on the filter grid 6, they are detected by the level detector and a signal is given to start the slag discharger to discharge them. The sewage after sedimentation and separation flows into the sewage tank 2 through the U-shaped pipe 8 from the lower part of the separation tank 1. The secondary sewage in the sewage tank 2 accumulates to a certain height and is discharged by the secondary sewage pump. The expulsion system composed of the circulation pump 3, the circulation pipe 4 and the expulsion nozzle 13 is started regularly or irregularly to remove the sediment. The fine garbage that falls is driven to the primary sewage pump for discharge to realize the self-cleaning function. In addition, the secondary sewage is connected to the heating and pressurizing device 7, the hot water pipe 10 and the hot water nozzle 9 to form a grid hot washing system, which is started regularly or irregularly to perform hot water cleaning on the grid to achieve the cleaning purpose. The fine garbage is removed by the separation tank 1 and the sewage in the sewage tank 2 floats up. The upper sewage is pumped out by the secondary sewage pump. The discharged water can be pumped into the heating and pressurizing device 7, and after heating, it is transported to the hot water nozzle 9 through the hot water pipe 10, and sprayed out from time to time to rinse and clean the surface of the filter grid 6 below with hot water to prevent the grid from being uncleaned for a long time and affecting the filtering effect and causing blockage.
