Description

Technical Field

[0001] This utility model relates to the field of settling tank technology, specifically a settling tank for industrial-grade mixed oil production. Background Technology

[0002] Industrial-grade blended oil is produced from waste oils from the catering, food, or slaughtering industries, as well as non-edible oils produced in agriculture. It undergoes dehydration, impurity removal, acid reduction, decolorization, and deodorization processes. It can only be used in chemical production and is prohibited for consumption. It can be used as a feedstock for biodiesel, plasticizers, oleic acid, and anti-caking agents, among other applications in their production and processing. During the production of industrial-grade blended oil, it needs to be poured into settling tanks for sedimentation treatment.

[0003] Currently, after mixed oil settles in a settling tank, the sediment adheres to the inner wall of the tank, making cleaning difficult. If not removed over a long period, it will affect the settling quality of the mixed oil. Therefore, those skilled in the art have provided an industrial-grade settling tank for mixed oil production to solve the problems mentioned in the background art. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a settling tank for industrial-grade mixed oil production, which solves the problem that sediments adhere to the inner wall of the tank, making cleaning difficult and affecting the settling quality of the mixed oil if not removed over a long period of time.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a settling tank for industrial-grade mixed oil production, comprising a tank body, an inlet pipe installed on the upper part of the tank body, a discharge pipe installed on the periphery of the tank body, a connecting pipe installed at the middle of the upper end of the tank body, a water inlet pipe connected to the bottom end of the connecting pipe, a retaining ring installed on the periphery of the bottom end of the connecting pipe, an annular retaining groove opened in the upper end port of the water inlet pipe, a fan blade installed on the inner wall of the water inlet pipe, a guide pipe connected to the periphery of the water inlet pipe, and a scraper provided on one side of the guide pipe.

[0006] Preferably, the connecting pipe is fixedly connected to the tank body, and the upper end of the connecting pipe is connected to a water supply pipe for transporting water.

[0007] Preferably, the retaining ring is rotatably engaged with the annular retaining groove, and the fan blade drives the water inlet pipe to rotate after being impacted by the water source.

[0008] Preferably, ball bearings are installed on the upper and lower inner walls of the annular groove, and the ball bearings contact the upper and lower inner walls of the retaining ring. The ball bearings are used to reduce the friction between the retaining ring and the annular groove.

[0009] Preferably, the end of the guide pipe near the inner wall of the tank is provided with a bend, the water source is sprayed through the guide pipe, and the recoil force of the spray from the guide pipe is in the same direction as the rotation of the inlet pipe due to the impact of the water flow.

[0010] Preferably, a connecting rod is installed on the outer wall of the water inlet pipe, and the water inlet pipe is connected to the scraper through the connecting rod.

[0011] Preferably, the scraper is inclined and fits against the inner wall of the tank, thus reducing resistance and preventing a decrease in the rotation speed of the inlet pipe when cleaning the inner wall of the tank.

[0012] Compared with the prior art, this utility model provides a settling tank for industrial-grade mixed oil production, which has the following beneficial effects:

[0013] Through design, the connecting pipe is rotatably engaged with the annular groove via a retaining ring, and several fan blades are installed below the annular groove. When water is supplied through the water supply pipe, the fan blades, impacted by the water source, drive the inlet pipe to rotate. The water source is sprayed through the guide pipe, and the recoil force of the spray from the guide pipe is in the same direction as the rotation of the inlet pipe due to the impact of the water flow, thereby improving the rotation efficiency of the inlet pipe. During the rotation of the inlet pipe, the guide pipe can clean the inner wall of the tank along with the rotation of the inlet pipe. Furthermore, a scraper is connected to one side of the inlet pipe, which contacts the inner wall of the tank. Due to the inclination of the scraper and its close contact with the inner wall of the tank, the resistance is small, and the rotation speed of the inlet pipe will not decrease when cleaning the inner wall of the tank. This mechanism can clean the inside of the settling tank and avoid problems with the settling quality of the mixed oil. Attached Figure Description

[0021] Please see Figure 1 , Figure 2 , Figure 3 This utility model provides a technical solution: a settling tank for industrial-grade mixed oil production, comprising a tank body 1, an inlet pipe 2 installed on the upper part of the tank body 1, a discharge pipe 3 installed on the periphery of the tank body 1, a connecting pipe 4 installed in the middle of the upper end of the tank body 1, a water inlet pipe 7 connected to the bottom end of the connecting pipe 4, a retaining ring 6 installed on the periphery of the bottom end of the connecting pipe 4, an annular groove 8 opened in the upper end port of the water inlet pipe 7, a fan blade 10 installed on the inner wall of the water inlet pipe 7, a guide pipe 11 connected to the periphery of the water inlet pipe 7, a scraper 13 provided on one side of the guide pipe 11, the connecting pipe 4 fixedly connected to the tank body 1, and a water supply pipe 5 connected to the upper end of the connecting pipe 4 for transporting water. The retaining ring 6 is rotatably engaged with the annular groove 8, and the fan blade 10 drives the water inlet pipe 7 to rotate after being impacted by the water source.

[0022] Please see Figure 2 , Figure 3 , Figure 4The annular groove 8 has ball bearings 9 installed on the upper and lower inner walls. The ball bearings 9 contact the upper and lower inner walls of the retaining ring 6. The ball bearings are used to reduce the friction between the retaining ring 6 and the annular groove 8. The end of the guide pipe 11 near the inner wall of the tank 1 is provided with a bend. Water is sprayed through the guide pipe 11, and the recoil force of the guide pipe 11 is in the same direction as the rotation of the inlet pipe 7 under the impact of the water flow. A connecting rod 12 is installed on the outer wall of the inlet pipe 7. The inlet pipe 7 is connected to the scraper 13 through the connecting rod 12. The scraper 13 is inclined and fits against the inner wall of the tank 1, so the resistance is small. When cleaning the inner wall of the tank 1, the rotation speed of the inlet pipe 7 will not decrease.

[0023] In this utility model, the top of the settling tank 1 is connected to the feed pipe 2, and the bottom side is connected to the discharge pipe 3. A connecting pipe 4 is installed on the top of the tank 1. The upper end of the connecting pipe 4 is connected to the water supply pipe 5, and the bottom of the connecting pipe 4 is connected to the water inlet pipe 7.

[0024] Furthermore, a retaining ring 6 is installed on the bottom periphery of the connecting pipe 4, and an annular groove 8 is opened on the inner side of the upper end port of the water inlet pipe 7. Ball bearings 9 are installed on the upper and lower inner walls of the annular groove 8. The connecting pipe 4 is rotatably engaged with the annular groove 8 through the retaining ring 6. Several fan blades 10 are arranged below the annular groove 8. The fan blades 10 are fixedly installed on the inner wall of the water inlet pipe 7. When water is supplied through the water supply pipe 5, water is injected into the water inlet pipe 7 through the connecting pipe 4. After being impacted by the water source, the fan blades 10 drive the water inlet pipe 7 to rotate.

[0025] A guide pipe 11 is connected to the periphery of the water inlet pipe 7. The outlet end of the guide pipe 11 is close to the inner wall of the tank 1. When the water inlet pipe 7 rotates, water is sprayed through the guide pipe 11. The recoil force of the spray from the guide pipe 11 is in the same direction as the rotation of the water inlet pipe 7 caused by the water flow, which can improve the rotation efficiency of the water inlet pipe 7. During the rotation of the water inlet pipe 7, the guide pipe 11 can clean the inner wall of the tank 1 along with the rotation of the water inlet pipe 7.

[0026] Furthermore, a scraper 13 is connected to one side of the water inlet pipe 7 via a connecting rod 12. The scraper 13 contacts the inner wall of the tank 1. Since the scraper 13 is inclined and fits against the inner wall of the tank 1, the resistance is small. When cleaning the inner wall of the tank 1, the rotation speed of the water inlet pipe 7 will not decrease.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
