Description

Technical Field

[0001] This utility model relates to the field of settling tank cleaning technology, and in particular to a degumming settling tank anti-wall-hanging cleaning device. Background Technology

[0002] Settling tanks are containers used for oil-water separation, primarily in oil extraction and wastewater treatment. They separate oil, water, and sediment through gravity. Settling tanks achieve solid-liquid or liquid-liquid separation based on gravity differences and are commonly used to treat oily wastewater, industrial wastewater, and for sludge thickening. In oil refining, degumming is a key process, primarily removing phospholipids, proteins, and other gum impurities from crude oil to improve its clarity and color. Common methods include alkali refining for deacidification and vacuum distillation. An existing crude oil settling device (announcement number: CN220609211U) lifts the entire cover plate upwards, thereby pulling the rotating shaft connected to the bottom of the motor upwards. When the rotating shaft moves upwards, it drives the support frame and the second mounting frame, which are connected to the outer wall via the connecting bearing, to move upwards. This allows the second mounting frame to scrape off the impurities adhering to the inner wall of the settling tank and drop them onto the filter screen. However, stubborn grease has a strong adhesion to the tank wall. Directly pulling the rotating shaft upwards to drive the second mounting frame to scrape off the impurities is difficult to completely remove the grease, which easily leads to residual oil stains on the tank wall. Furthermore, the scraped grease and impurities are prone to re-adhere to the tank wall due to air flow inside the tank or their own stickiness when falling, requiring repeated cleaning by the staff, which increases the operation steps and labor intensity. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a degumming settling tank anti-wall cleaning device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A degumming settling tank anti-wall-hanging cleaning device includes a support frame and a settling tank body. A water tank is provided on one side of the settling tank body. An installation box is embedded at the bottom of the water tank. A coil is installed inside the installation box. An air outlet pipe is fixed between one end of the coil and the top of the settling tank body. A water inlet pipe is fixed to the outer wall of the water tank. An air jet pipe is installed at the upper inside of the settling tank body by fasteners. A rotating rod is provided at the center of the inner side of the air jet pipe. An annular spray pipe is sleeved at the middle section of the rotating rod. A scraper is fixed to the outer wall of the rotating rod. A rotary joint is provided between the bottom end of the water inlet pipe and the annular spray pipe.

[0005] As a further embodiment of this utility model, a steam generator is provided on the side of the settling tank away from the water tank, and one end of the rotary joint is fixedly connected to the bottom end of the water inlet pipe.

[0006] As a further embodiment of this utility model, the end of the rotary joint away from the water inlet pipe is movably connected to the annular nozzle, and an air inlet pipe is fixed on the steam generator.

[0007] As a further embodiment of this utility model, the end of the air inlet pipe away from the steam generator is connected through to the top of the settling tank and is fixedly connected to the jet pipe.

[0008] As a further embodiment of this utility model, a motor is installed on the top of the settling tank by fasteners, and the motor is fixedly connected to the rotating rod through an output shaft.

[0009] As a further embodiment of this utility model, a drain pipe is fixed to the bottom end of the settling tank, and a drain valve is fixedly installed on the drain pipe.

[0010] As a further embodiment of this utility model, a water pump is fixedly installed on the water inlet pipe, an exhaust valve is fixedly installed on the air outlet pipe, and an extension pipe is fixedly installed at the end of the coil away from the air outlet pipe.

[0011] Compared with the prior art, the present invention has the following beneficial effects: In the cleaning operation of the settling tank, steam is introduced into the annular spray nozzle to evenly spray and cover the tank wall. The high-temperature steam first reduces the adhesion between the grease and the inner wall of the settling tank. After the grease on the wall is fully softened, the motor is started to drive the rotating rod to rotate. The evenly distributed scraper blades on the rotating rod rotate synchronously. Through the physical scraping force of the scraper blades, the softened grease on the tank wall is completely peeled off. At the same time, the residual steam inside the settling tank that has not been completely consumed is introduced into the coil inside the water tank. The waste heat of the steam is used to continue to heat the cold water in the water tank, realizing the secondary utilization of steam energy. With the help of the rotary joint, the heated hot water can flow steadily into the jet pipe that rotates with the rotating rod, and the scraping action of the scraper blades is synchronized to flush the peeled grease to the bottom of the tank, ensuring that the tank wall is clean and free of residue, providing a clean environment for the subsequent degumming operation.

[0017] Reference Figures 1-5A degumming settling tank anti-wall cleaning device includes a support frame 1 and a settling tank 2. A water tank 3 is provided on one side of the settling tank 2. An installation box 301 is embedded at the bottom of the water tank 3. A coil 306 is installed inside the installation box 301. An air outlet pipe 304 is fixed between one end of the coil 306 and the top of the settling tank 2. A water inlet pipe 302 is fixed to the outer wall of the water tank 3. An air jet pipe 6 is installed at the upper inside of the settling tank 2 by fasteners. A rotating rod 203 is provided at the center of the inner side of the air jet pipe 6. An annular spray pipe 206 is sleeved at the middle section of the rotating rod 203. A scraper 204 is fixed to the outer wall of the rotating rod 203. A rotary joint 5 is provided between the bottom end of the water inlet pipe 302 and the annular spray pipe 206.

[0018] The steam generator 4 is started, and the steam it generates is delivered to the jet pipe 6 through the air inlet pipe 401. The steam is then evenly sprayed onto the inner wall of the settling tank 2 through the jet pipe 6 to fully soften the adhering grease. Then, the motor 205 is started, and the motor 205 drives the rotating rod 203 to rotate. The rotating rod 203 drives each set of scraper blades 204 to rotate, and under the action of the rotary joint 5, the rotating rod 203 drives the annular spray pipe 206 to rotate together. With the physical scraping force of the scraper blades 204, the softened grease adhering to the tank wall is completely removed. Then, the residual steam that has not been completely consumed inside the settling tank 2 is discharged through the air outlet pipe. 304 is introduced into coil 306, and the waste heat of steam is used to heat the cold water in water tank 3. After the water temperature in water tank 3 reaches the appropriate temperature for decontamination, water pump 303 is started, so that the heated hot water is delivered to annular spray pipe 206 through inlet pipe 302. The hot water is sprayed directionally onto the tank wall from several oblique spray holes opened in the annular spray pipe 206, keeping pace with the scraping action of scraper 204, so that the grease attached to the wall peeled off by scraper 204 is flushed to the bottom of the tank in time. After the cleaning operation is completed, drain valve 202 is opened to let the grease-containing wastewater be discharged through drain pipe 201, so as to reserve a clean tank environment for subsequent degumming operation.

[0019] In this embodiment, a steam generator 4 is provided on the side of the settling tank 2 away from the water tank 3, and one end of the rotary joint 5 is fixedly connected to the bottom end of the water inlet pipe 302.

[0020] Steam is evenly sprayed out through several exhaust holes on the jet pipe 6, covering the inner wall of the settling tank 2, breaking down the structure of stubborn grease molecules, thereby reducing their adhesion to the metal tank wall and completing the grease softening pretreatment.

[0021] In this embodiment, the end of the rotary joint 5 away from the water inlet pipe 302 is movably connected to the annular nozzle 206, and the steam generator 4 is fixed with an air inlet pipe 401.

[0022] The two ends of the rotary joint 5 are connected and fixed to the water inlet pipe 302 and the annular nozzle 206 respectively, which ensures that the hot water delivered by the water inlet pipe can flow steadily into the annular nozzle 206, and does not hinder the rotating rod 203 from driving the annular nozzle 206 to rotate synchronously.

[0023] In this embodiment, the end of the air inlet pipe 401 away from the steam generator 4 passes through and connects to the top of the settling tank 2, and is fixedly connected to the jet pipe 6.

[0024] The scraper 204 is made of wear-resistant rubber and can rotate under the drive of the rotating rod 203. It can completely remove the grease softened by steam through physical scraping force, while the rubber material can prevent scratching the can wall.

[0025] In this embodiment, a motor 205 is installed on the top of the settling tank 2 by fasteners, and the motor 205 is fixedly connected to the rotating rod 203 through the output shaft.

[0026] The annular nozzle 206 has several water outlets, which are used to flush the inner wall of the settling tank 2 with hot water, thereby washing away the scraped grease and impurities and reducing the secondary adhesion of grease.

[0027] In this embodiment, a drain pipe 201 is fixed to the bottom of the settling tank 2, and a drain valve 202 is fixedly installed on the drain pipe 201.

[0028] The residual steam that is not completely consumed in the settling tank 2 is introduced into the coil 306 through the vent pipe 304, so as to realize the secondary utilization of steam energy and avoid the heat waste caused by the direct discharge of the residual steam after softening the grease.

[0029] In this embodiment, a water pump 303 is fixedly installed on the water inlet pipe 302, an exhaust valve 305 is fixed on the air outlet pipe 304, and an extension pipe 7 is fixed at the end of the coil 306 away from the air outlet pipe 304.

[0030] By utilizing the thermal conductivity of coil 306, the cold water in water tank 3 can be heated, and the excess condensate generated by coil 306 can be discharged through extension pipe 7.

[0031] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: When carrying out the anti-fouling cleaning operation of the settling tank 2, the steam generator 4 is first started, and the steam generated is transported to the jet pipe 6 through the air inlet pipe 401. Then, the steam is evenly sprayed onto the inner wall of the settling tank 2 through the jet pipe 6. After the high-temperature steam acts continuously for a period of time to fully soften the adhering grease, the motor 205 is started, and the motor 205 drives the rotating rod 203 to start rotating. The rotating rod 203 drives each set of scraper blades 204 to rotate, and under the action of the rotary joint 5, the rotating rod 203 drives the annular spray pipe 206 to rotate together. With the help of the physical scraping force of the scraper blades 204, the softened grease adhering to the tank wall is completely peeled off. Next, the exhaust valve 305 is opened to introduce the residual steam that has not been completely consumed inside the settling tank 2 into the coil 306 through the exhaust pipe 304. The residual heat of the steam is used to heat the cold water in the water tank 3. After the water temperature in the water tank 3 reaches the appropriate temperature for decontamination, the water pump 303 is started to deliver the heated hot water through the inlet pipe 302 to the annular spray pipe 206. The hot water is sprayed directionally onto the tank wall from several oblique spray holes on the annular spray pipe 206, keeping pace with the scraping action of the scraper 204. The grease that is peeled off by the scraper 204 is promptly flushed to the bottom of the tank. After the cleaning operation is completed, the drain valve 202 is opened to allow the grease-containing wastewater to be discharged through the drain pipe 201, thus reserving a clean tank environment for the subsequent degumming operation.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
