Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and in particular relates to a sewage oil removal device. Background Art

[0002] Sewage refers to the discharged water from life and production that is polluted to a certain extent. Floating oil in industrial production and animal and plant oils in catering sewage are organic pollutants in sewage that are difficult to remove and degrade. Before sewage is discharged, it needs to be treated. Due to the different densities of oil and water, stratification will occur when oil and water are mixed. The current oil removal device uses the principle that oil will solidify when it is cooled. An ice-water mixture is passed into the oil suction roller to lower the temperature. The floating oil on the surface of the sewage will solidify when it contacts the oil suction rod, thereby achieving oil-water separation. When this method is used to remove oil, a large amount of sewage will not be mixed in the oil, and the oil and water are separated thoroughly, but the oil removal efficiency is slow, which affects the efficiency of sewage treatment.

The installation basket 61 is installed with a branch pipe 2 63 connected to the groove of the liquid storage block 62;

[0021] The oil removal mechanism 7 includes an electric telescopic rod 71, a motor 72, a refrigeration plate 73, an electric threaded rod 74, a mounting frame 75 and an oil storage tank 76. The oil storage tank 76 and the mounting frame 75 are provided on both sides of the liquid storage mechanism 6. A scraper is provided on the inner wall of the oil storage tank 76. The electric threaded rod 74 is installed on the mounting frame 75. The electric telescopic rod 71 is installed on the electric threaded rod 74. The cross bar of the mounting frame 75 passes through the electric telescopic rod 71. The electric telescopic rod 71 is installed with a motor 72, and the refrigeration plate 73 is installed on the motor 72.

[0022] The electric auger 2 can send the solid matter in the sewage sent into the storage tank 1 into the solid storage tank 3, and the filter screen 32 can filter out the liquid attached to the solid. The holes on the electric auger 2 ensure that the liquid can enter the drainage tank 11. The heating plate 5 installed inside the drainage tank 11 will heat the sewage. When the sewage is heated, the oil in the sewage will float up. The fan 4 can send hot air into the drainage tank 11 through the branch pipe 41. A valve is installed on the pipe mouth of the branch pipe 41 to prevent the sewage in the drainage tank 11 from leaking. The oil in the sewage will rise rapidly under the action of the hot air. As the sewage flows, the liquid separator 12 will move the water body The part of the sewage located above the liquid separation plate 12 will enter the liquid storage block 62 with the oil, and the rest of the sewage will leave the drainage tank 11 through the infusion channel 13. The liquid storage block 62 can be moved by moving the bottom plate 64, so as to change the top surface groove of the liquid storage block 62 for collecting the sewage with oil, so as to ensure that the liquid storage block 62 can continue to collect sewage when the oil removal mechanism 7 removes the oil in the sewage. The installation basket 61 is used to install the liquid storage block 62, which can avoid the leakage of sewage during the movement of the liquid storage block 62, and ensure the working effect of the liquid storage mechanism 6. The sewage after the oil is removed will be discharged from the top surface groove of the liquid storage block 62 through the branch pipe 2 63;

[0023] When the cooling plate 73 comes into contact with the oil floating on the water surface, the oil will adhere to the surface of the cooling plate 73, which is convenient for the user to collect the oil. The position of the cooling plate 73 can be controlled by the electric telescopic rod 71, which is convenient for the user to process the oil in the sewage. The electric telescopic rod 71 is installed on the electric threaded rod 74 through a thread. When the electric threaded rod 74 rotates, the electric telescopic rod 71 starts to move under the action of the thread. The electric telescopic rod 71 is penetrated by the cross bar of the mounting frame 75 to prevent the electric telescopic rod 71 from rotating during the movement, thereby ensuring the stability of the electric telescopic rod 71 during the movement. The motor 72 can rotate with the cooling plate 73, and the oil on the cooling plate 73 can be scraped off the cooling plate 73 through the cooperation of the inner wall scraper of the oil storage tank 76 and the rotating cooling plate 73, thereby realizing the collection of the oil. The position of the oil storage tank 76 reduces the moving distance of the cooling plate 73 with oil stains attached, thereby improving the efficiency of the oil storage tank 76 in collecting oil.

[0024] Specifically, a groove communicating with the drainage groove 11 is provided on the top surface of the liquid storage block 62 , the bottom surface of the groove communicating with the drainage groove 11 is an inclined surface, and a groove communicating with the drainage groove 11 is provided on the side wall of the mounting basket 61 .

[0025] The cooperation between the side wall groove of the mounting basket 61 and the groove connecting the liquid storage block 62 with the drainage trough 11 ensures that the sewage can enter the top surface groove of the liquid storage block 62. The bottom surface shape of the top surface groove of the liquid storage block 62 ensures that the sewage with oil can smoothly enter the top surface groove of the liquid storage block 62. The top of the inclined bottom surface of the liquid storage block 62 is on the same plane as the bottom surface of the side wall groove of the mounting basket 61, ensuring the working effect of the side wall groove of the mounting basket 61 and the groove connecting the liquid storage block 62 with the drainage trough 11.

[0026] Specifically, a heating plate is installed inside the scraper of the oil storage tank 76 .

[0027] The heating plate installed inside the scraper of the oil storage tank 76 can heat the scraper. The heated scraper can easily scrape off the oil stains attached to the refrigeration plate 73, thereby ensuring the working effect of the scraper.

[0028] Specifically, the second branch pipe 63 is installed between the installation basket 61 and the liquid storage block 62 and is connected via a hose, and a valve is provided on the branch of the second branch pipe 63 .

[0029] The hose ensures that the moving liquid storage block 62 will not affect the working effect of the branch pipe 2 63 , and the valve provided on the branch of the branch pipe 2 63 facilitates the user to discharge the sewage inside the top surface groove of the liquid storage block 62 .

[0030] Specifically, the heating plate 5 installed on the drainage trough 11 is divided into two layers. The heating plate 5 located at the bottom is installed on the bottom surface of the drainage trough 11, and the heating plate 5 located at the top is shaped like a cuboid with its edge facing downward.

[0031] By setting up two layers of heating plates 5, the heating effect of the heating plates 5 is guaranteed, and the efficiency of the heating plates 5 in heating sewage is improved. The shape of the upper heating plates 5 ensures that the upper heating plates 5 will not hinder the movement of oil stains, thereby ensuring the working effect of the device.

[0032] Specifically, the upper feeding channel 31 is inclined toward the solid storage tank 3 , the position where the upper feeding channel 31 communicates with the storage tank 1 is higher than the feed port of the storage tank 1 , and the lower feeding channel 31 is inclined toward the storage tank 1 .

[0033] The shape of the feeding channel 31 ensures that the movement of solids and sewage will not be affected, thereby ensuring the working effect of the solid storage tank 3. The position of the upper feeding channel 31 installed on the side wall of the storage tank 1 ensures that when the electric auger 2 rises with solids, the holes on the electric auger 2 can separate the sewage from the accumulated solids on the blades of the electric auger 2, thereby reducing the amount of sewage entering the solid storage tank 3.

[0034] Specifically, a filter is installed on the hole of the electric auger 2.

[0035] The filter screen arranged on the hole of the electric auger 2 improves the working effect of the electric auger 2 and prevents small solid impurities from entering the drainage tank 11 through the hole of the electric auger 2 .

[0036] The working principle and use process of the utility model are as follows: start the electric auger 2, the fan 4 and the heating plate 5, and send the sewage into the storage tank 1 through the drainage trough 11. The electric auger 2 will send the solid debris in the sewage to the solid storage tank 3, and the sewage enters the drainage trough 11. The sewage entering the drainage trough 11 is heated by the hot air sent from the heating plate 5 and the fan 4. The oil in the sewage will float to the water surface under the action of the hot air. During the flow of sewage, the sewage without oil will leave the drainage trough 11 through the infusion channel 13, and the water with oil will enter the top surface groove of the storage block 62. After the water inside the top surface groove of the storage block 62 reaches a certain amount, start the movable bottom plate 64, replace the top surface groove of the storage block 62 connected to the drainage trough 11, start the electric threaded rod 74, and the electric telescopic rod 71 with the control The cold plate 73 moves to the top of the groove on the top surface of the liquid storage block 62 that is not connected to the drainage trough 11, and the heating plates inside the scrapers of the cold plate 73 and the oil storage tank 76 are started, and the electric telescopic rod 71 is controlled to extend, and the cold plate 73 contacts the water surface with oil stains, and the oil solidifies on the cold plate 73. The cold plate 73 enters the oil storage tank 76 through the cooperation of the electric telescopic rod 71 and the electric threaded rod 74, and the cold plate 73 contacts the scraper of the oil storage tank 76, and the motor 72 is started. The cold plate 73 starts to rotate under the action of the motor 72, and the oil attached to the cold plate 73 is scraped into the inside of the oil storage tank 76 through the cooperation of the scraper of the oil storage tank 76 and the rotating cold plate 73. The above actions are repeated until the oil in the sewage is cleaned up, and then the valve on the branch pipe 2 63 and the connected branch is opened to discharge the cleaned sewage.
