Description

Technical Field

[0001] This utility model relates to the field of mixing tank cleaning technology, specifically a mixing tank inner wall structure that is easy to clean. Background Technology

[0002] A mixing tank is a device used for stirring, mixing, blending, and homogenizing materials. It is widely used in industries such as coatings, pharmaceuticals, building materials, chemicals, pigments, resins, food, and scientific research. Due to its wide range of applications, mixing tanks are often used for stirring and mixing different materials. Before use, the inside of the mixing tank needs to be cleaned to prevent contamination between different materials.

[0003] Existing technologies, such as the one disclosed in CN220425205U, include a mixing tank that is easy to clean. The cleaning mechanism on the inner wall of the mixing tank has a simple structure, but the cleaning effect of simply using a scraper is poor and cannot be completely cleaned. In addition, the contact area between the scraper and the inner wall of the tank is small, resulting in insufficient cleaning. Furthermore, after rinsing, the existing mixing tank needs to be left to dry, which is slow and results in low production efficiency. Utility Model Content

A three-dimensional rotating nozzle is fixedly connected to the bottom of a water supply pipe and fixedly connected to the top of a vertical rod. A slot is opened on the side wall of the vertical rod. The connection between the three-dimensional rotating nozzle and the water supply pipe is located above the slot and is fixedly connected to the inner wall of the vertical rod through a connecting block. The nozzle of the three-dimensional rotating nozzle extends to the slot and faces the slot direction. A scraper is connected to the vertical rod and is located outside the stirring blade. A drying pipe is provided inside the tank, and a nozzle facing the inner wall of the tank is fixedly connected to the drying pipe. An air pump is fixedly connected to the top of the tank, and an air supply pipe is fixedly connected between the drying pipe and the air pump. A box is fixedly connected to the tank, and the box is filled with desiccant. A connecting pipe connects the air pump and the box, and an air filter is fixedly connected at the connection. Several ventilation openings are opened on the outer wall of the box.

[0006] As mentioned above, there are two scrapers, both of which are T-shaped rubber plates, and the two scrapers are symmetrically distributed on the left and right sides of the vertical rod. The drying tube is annular, and there are several nozzles, which are evenly distributed around the drying tube.

[0007] As described above, a telescopic cylinder is fixedly connected to the top of the tank, and an opening is provided on the top of the tank. The telescopic end of the telescopic cylinder passes through the opening and is fixedly connected to the drying pipe. The gas supply pipe is an elastic spiral gas pipe.

[0008] As described above, the vertical rod is provided with a movable tube, which is sleeved on the outside of the three-dimensional rotating nozzle, and the bottom end of the movable tube is closed. A push-pull cylinder is fixedly connected to the bottom end of the movable tube, and the push-pull cylinder is fixedly connected to the inside of the vertical rod.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1-4 As shown, this utility model provides a technical solution: an easy-to-clean inner wall structure for a mixing tank, including a tank body 1, a stirring rod inside the tank body 1, the stirring rod consisting of a vertical rod 6 and stirring blades, a motor 2 for driving the stirring rod fixedly connected to the top of the tank body 1, an inlet and an outlet with valves respectively provided on the side wall and bottom of the tank body 1, a support plate fixedly connected to the bottom of the tank body 1, the two ends of the vertical rod 6 being movably connected to the top of the tank body 1 and the support plate respectively through bearings, and the top of the vertical rod 6 extending outside the tank body 1, two meshing bevel gears 4 provided at the top of the tank body 1, and the two bevel gears 4 being fixedly connected to the top of the vertical rod 6 and the output end of the motor 2 respectively, the vertical rod 6 being hollow and having an open top through which the bevel gears 4 pass, a water supply pipe 13 provided inside the vertical rod 6, the top of the water supply pipe 13 being fixed to the top of the vertical rod 6. The water supply pipe 13 is fixedly connected to a three-dimensional rotating nozzle 11 at its bottom end. The vertical rod 6 has a slot on its side wall. The connection between the three-dimensional rotating nozzle 11 and the water supply pipe 13 is located above the slot and is fixedly connected to the inner wall of the vertical rod 6 through a connecting block. The nozzle of the three-dimensional rotating nozzle 11 extends to the slot and faces the slot direction. A scraper 8 is connected to the vertical rod 6 and is located outside the stirring blade. A drying pipe 7 is provided inside the tank 1. A nozzle facing the inner wall of the tank 1 is fixedly connected to the drying pipe 7. An air pump 3 is fixedly connected to the top of the tank 1, and an air supply pipe 9 is fixedly connected between the drying pipe 7 and the air pump 3. A box 18 is fixedly connected to the tank 1. The box 18 is filled with desiccant. A connecting pipe is connected between the air pump 3 and the box 18, and an air filter is fixedly connected at the connection. Several ventilation holes are opened on the outer wall of the box 18.

[0023] According to the overall structure of the device, when in use, the device is connected to an external power source, and the top of the water supply pipe 13 is connected to an external water source. Then, the motor 2 is started and water is supplied to the water supply pipe 13. The water is supplied to the three-dimensional rotating nozzle 11 through the water supply pipe 13. The three-dimensional rotating nozzle 11 sprays water onto the inner wall of the tank 1. The three-dimensional rotating nozzle 11 can rotate, which increases the spraying area and coverage of the water flow. At the same time, the motor 2 drives the vertical rod 6 to rotate through the bevel gear 4, which drives the scraper 8 to rotate and scrape off the residue on the inner wall of the tank 1. After that, the flushing water and residue are discharged from the discharge pipe. After the flushing is completed, the air pump 3 is started. The air pump 3 delivers the dried and filtered dry air to the drying pipe 7 and blows it onto the inner wall of the tank 1, thereby drying the inner wall of the tank 1.

[0024] like Figure 2 As shown, there are two scrapers 8, both of which are U-shaped rubber plates, and the two scrapers 8 are symmetrically distributed on the left and right sides of the vertical rod 6. The drying tube 7 is annular, and there are several nozzles, which are evenly distributed around the drying tube 7.

[0025] The two symmetrically distributed scrapers 8 increase the contact surface of the scrapers 8, thereby improving the cleaning efficiency. The rubber plate structure ensures that the scrapers 8 will not damage the tank 1 when they rotate. The annular drying pipe 7 and several nozzles increase the contact surface between the drying air and the inner wall of the tank 1, thereby improving the drying efficiency.

[0026] like Figure 1 , 2 As shown, a telescopic cylinder 5 is fixedly connected to the top of the tank body 1. An opening is provided on the top of the tank body 1. The telescopic end of the telescopic cylinder 5 passes through the opening and is fixedly connected to the drying pipe 7. The gas supply pipe 9 is an elastic spiral gas pipe.

[0027] The extension and retraction of the telescopic cylinder 5 drives the drying tube 7 to move up and down, so that the drying tube 7 can fully and completely dry the inner wall of the tank 1. The elastic spiral cylinder ensures the connection between the drying tube 7 and the air pump 3 during the up and down movement. When moving upward, the air tube can automatically retract, thereby preventing the air tube from falling down and interfering with the rotation of the scraper 8 and the stirring rod.

[0028] like Figure 3 As shown, the vertical rod 6 is provided with a movable tube 16, which is sleeved on the outside of the three-dimensional rotating nozzle 11. The bottom end of the movable tube 16 is closed. A push-pull cylinder 10 is fixedly connected to the bottom end of the movable tube 16, and the push-pull cylinder 10 is fixedly connected to the inside of the vertical rod 6. Sealing rings are sleeved on the outside of the movable tube 16 near both ends.

[0029] The slot is sealed by the movable tube 16, which separates the three-dimensional rotating nozzle 11 from the space inside the tank 1, so that the material will not enter the vertical rod 6 when the mixing tank is performing the mixing operation, thereby preventing the material from entering the vertical rod 6 and clogging the three-dimensional rotating nozzle 11.

[0030] like Figure 3 , 4 As shown, both ends of the scraper 8 are provided with fixing tubes 17 at the connection points with the vertical rod 6. The fixing tubes 17 are fixedly connected to the vertical rod 6, and both ends of the scraper 8 are inserted into the adjacent fixing tubes 17. The lower fixing tube 17 is connected to the interior of the vertical rod 6. The push-pull cylinder 10 is a double-ended cylinder. The top telescopic end of the push-pull cylinder 10 is fixedly connected to the movable tube 16. Its bottom telescopic end is movably connected to two connecting plates 14 through a rotating shaft, and the two connecting plates 14 are movably connected to the bottom ends of the scrapers 8 on both sides through a rotating shaft.

[0031] By using a double-ended cylinder and connecting the bottom of the double-ended cylinder and the scraper 8 via a connecting plate 14, the movement of the movable tube 16 and the scraper 8 is linked. When the extension rod of the push-pull cylinder 10 moves the movable tube 16 downward, the connection between the extension rod of the push-pull cylinder 10 and the connecting plate 14 moves downward synchronously. Because the scraper 8 is restricted at both ends by the fixed tube 17, the connecting plate deflects, thereby pushing the scraper 8 laterally away from the vertical rod 6. This allows the scraper 8 to unfold and fit against the inner wall of the tank 1, so that the scraper 8 can follow the rotation of the vertical rod 6. During the cleaning process, the scraper 8 scrapes off the residue and other materials remaining on the inner wall of the tank 1. At the end of the cleaning, the extension rod of the push-pull cylinder 10 moves upward, and the connecting plate 14 moves the scraper 8 away from the inner wall of the tank 1, thereby retracting the scraper 8 and allowing the drying tube 7 to move smoothly up and down.

[0032] like Figure 3 As shown, a baffle 15 is provided at the end of the fixed tube 17 away from the vertical rod 6, the end of the scraper 8 passes through the baffle 15, and a corrugated pipe 12 is fixedly connected between the baffle 15 and the fixed tube 17.

[0033] The sliding gap between the fixed pipe 17 and the scraper 8 is sealed by the baffle 15 and the corrugated pipe 12 to prevent material from entering the fixed pipe 17 and the vertical rod 6 and causing blockage that affects the movement of the components.

[0034] Working principle: In use, connect the device to an external power source and connect the top of the water supply pipe 13 to an external water source. Then start the motor 2 and the push-pull cylinder 10 to supply water to the water supply pipe 13. The extension end of the push-pull cylinder 10 moves down, causing the movable pipe 16 to move down, exposing the three-dimensional rotating nozzle 11. Water is then supplied from the water supply pipe 13 into the three-dimensional rotating nozzle 11, which sprays water onto the inner wall of the tank 1. The three-dimensional rotating nozzle 11 can rotate, increasing the spray area and coverage of the water flow. At the same time, the extension end of the push-pull cylinder 10 moves down... When the scraper is moved away from the vertical rod 6 through the connecting part, the scraper 8 is pushed to fit against the inner wall of the tank 1. The motor 2 drives the vertical rod 6 to rotate through the bevel gear 4, which in turn drives the scraper 8 to rotate, scraping off the residue on the inner wall of the tank 1. After that, the flushing water and residue are discharged from the discharge pipe. After the flushing is completed, the air pump 3 and the telescopic cylinder 5 are started. The air pump 3 delivers the dried and filtered air into the drying pipe 7 and blows it toward the inner wall of the tank 1. At the same time, the telescopic cylinder 5 drives the drying pipe 7 to move up and down, thereby blowing and drying the inner wall of the tank 1.

[0035] 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.
