Description

Technical Field

[0001] This utility model relates to the field of ingredient tank technology, specifically to an ingredient mixing tank with a rapid cleaning function. Background Technology

[0002] Mixing tanks with cleaning functions are key equipment in the chemical, food, and pharmaceutical industries for mixing, reacting, and batching materials. After processing a batch of materials, residual materials often adhere to the inner wall of the tank, the stirring shaft, and the stirring components. To prevent cross-contamination between different batches of materials and to ensure product quality and production safety, the inside of the mixing tank must be cleaned.

[0003] Currently, most existing mixing tanks with cleaning functions employ a combined cleaning method of fixed spray balls and agitation. Typically, one or more fixed spray heads or spray balls are installed on the top or side wall of the tank. During cleaning, a certain amount of cleaning solution is injected into the tank, and an external pump is activated to pressurize the solution and spray it into the tank through the spray heads. Simultaneously, the agitator shaft is driven to rotate, causing the agitator blades to rotate, agitating the cleaning solution inside the tank, causing it to flow and flush the internal space, thereby achieving the cleaning purpose.

[0004] However, this method has obvious drawbacks in actual use: because the cleaning fluid needs to fill the entire tank to achieve full coverage, the amount of cleaning fluid used is large; at the same time, relying on the stirring blades to drive the liquid flow for cleaning is not only inefficient, but also has cleaning dead spots, especially the cleaning effect on the tank wall, stirring shaft and complex components is not good; in addition, the whole cleaning process takes a long time, which seriously affects the equipment utilization rate and production efficiency.

[0005] To address the problems of low cleaning efficiency, incomplete cleaning, and high resource consumption in existing technologies, this utility model provides a batching and mixing tank with a rapid cleaning function, which achieves efficient, rapid, and thorough cleaning through structural innovation. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a mixing tank with a rapid cleaning function, which solves the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A mixing tank with a quick-cleaning function, including:

[0009] The mixing tank shell has an inlet at the top and a outlet at the bottom;

[0010] A stirring shaft is vertically and rotatably mounted on the top of the mixing tank shell, with its bottom end extending into the interior of the mixing tank shell. A stirring unit is symmetrically mounted on the outer wall of the end of the stirring shaft that extends into the interior of the mixing tank shell. The stirring unit includes a stirring sleeve rod fixedly mounted on the stirring shaft in a vertical linear array. A drive cavity is opened at the end of the stirring sleeve rod away from the stirring shaft. A stirring connecting rod is horizontally movably inserted through the stirring sleeve rod and located in the drive cavity. The cross-section between the outer wall of the stirring connecting rod and the inner wall of the stirring sleeve rod is in contact. Multiple stirring connecting rods located on the same side of the stirring sleeve rod are fixedly mounted at their ends and are in contact with the inner wall of the mixing tank shell. A linear actuator for driving the stirring connecting rod to slide is fixedly mounted on the stirring sleeve rod located in the middle and located in the drive cavity.

[0011] The central water supply pipe is vertical and extends through the top of the batching tank shell. A ring spray pipe is fixedly connected to the bottom of the central water supply pipe and inside the batching tank shell. The central water supply pipe and the top of the ring spray pipe are connected through each other. The outer and inner walls of the ring spray pipe are arranged in a ring array with multiple spray holes that are connected to the inside. There is a gap between the outer wall of the ring spray pipe and the inner wall of the batching tank shell. When the scraper is attached to the end of the stirring sleeve, the scraper is located inside the ring spray pipe.

[0012] The lifting mechanism is installed on the shell of the mixing tank and connected to the annular spray pipe. The lifting mechanism is used to make the annular spray pipe slide along the central water supply pipe or stop sliding.

[0013] The bottom valve mechanism is installed on the shell of the batching tank and is used to block or unblock the discharge port.

[0014] This invention provides a mixing tank with a rapid cleaning function. Compared with the prior art, it has the following advantages:

[0015] 1. By designing a central water supply pipe, annular spray pipe, and lifting mechanism, the inner wall of the main tank, as well as the surfaces of the stirring shaft, stirring sleeve, scraper, and stirring rod, are flushed. This replaces the existing method of injecting cleaning fluid into the main tank, causing the stirring shaft to rotate and the stirring blades to rotate, allowing the cleaning fluid in the main tank to flow and clean the inside of the mixing tank, thereby improving the cleaning efficiency of this mixing tank.

[0016] 2. Through the design of the sealing ring gasket, when the valve plate fits against the bottom of the mixing tank shell to block the discharge port, the sealing ring gasket forms contact with the bottom of the mixing tank shell, increasing the fit between the valve plate and the mixing tank shell and increasing the sealing performance between the valve plate and the mixing tank shell.

[0017] 3. During cleaning, the lid can rotate relative to the main tank. During the cleaning process, the lid drive motor is turned on, driving the active bevel gear to rotate. This causes the driven bevel gear to rotate the lid on the main tank. At the same time, the stirring drive motor is turned on, causing the stirring shaft to rotate in opposite directions on and between the lid. This allows the annular spray pipe to move downwards along the central water pipe, thus more thoroughly rinsing the inner wall of the main tank and the surfaces of the stirring shaft, stirring sleeve, scraper, and stirring rod, further improving the cleaning effect.

[0027] Example

[0028] To address the technical problems in the background section, the following batching and mixing tank with rapid cleaning function is provided:

[0029] like Figure 1 As shown, the mixing tank with rapid cleaning function provided by this utility model includes:

[0030] The mixing tank shell 1 has a feed inlet at the top and a discharge outlet at the bottom;

[0031] A stirring shaft 2 is vertically and rotatably mounted on the top of the mixing tank shell 1. A stirring drive motor is fixedly mounted on the top of the mixing tank shell 1. A bevel gear 1 is coaxially fixed to the output shaft of the stirring drive motor. A bevel gear 2 that meshes with bevel gear 1 is coaxially fixed to the stirring shaft 2. When in use, the stirring drive motor is turned on, and the stirring drive motor drives the stirring shaft 2 to rotate through bevel gear 1 and bevel gear 2. The bottom end of the stirring shaft 2 extends into the interior of the mixing tank shell 1. A stirring unit is symmetrically mounted on the outer wall of the end of the stirring shaft 2 that extends into the interior of the mixing tank shell 1. The stirring unit includes stirring sleeve rods 3 that are fixedly mounted on the stirring shaft 2 in a vertical linear array.

[0032] In this embodiment, such as Figure 5As shown, there are three stirring sleeve rods 3. A drive cavity 31 is opened at the end of the stirring sleeve rod 3 away from the stirring shaft 2. A stirring connecting rod 32 is horizontally movably inserted through the stirring sleeve rod 3 and located in the drive cavity 31. The cross section between the outer wall of the stirring connecting rod 32 and the inner wall of the stirring sleeve rod 3 is in contact. Multiple stirring connecting rods 32 located on the same side of the stirring sleeve rod 3 are fixedly installed at their ends, and scraper plates 33 are in contact with the inner wall of the mixing tank shell 1. A linear actuator 34 for driving the stirring connecting rod 32 to slide is fixedly installed on the stirring sleeve rod 3 located in the middle and located in the drive cavity 31. The two linear actuators 34 are synchronously controlled by an external controller.

[0033] A central water supply pipe 4 is vertical and extends through the top of the mixing tank shell 1. In this embodiment, a corrugated hose is fixedly installed on the top of the central water supply pipe 4, and the central water supply pipe 4 is connected to the outlet of the external cleaning liquid delivery pump through the corrugated hose. An annular spray pipe 41 is fixedly connected to the bottom of the central water supply pipe 4 and inside the mixing tank shell 1. The central water supply pipe 4 and the top of the annular spray pipe 41 are connected through each other. The outer and inner walls of the annular spray pipe 41 are arranged in an annular array with multiple spray holes 42 that are connected to the inside of the annular spray pipe 41. There is a gap between the outer wall of the annular spray pipe 41 and the inner wall of the mixing tank shell 1. When the scraper 33 is attached to the end of the stirring sleeve 3, the scraper 33 is located inside the annular spray pipe 41.

[0034] The lifting mechanism 5 is installed on the mixing tank shell 1 and connected to the annular spray pipe 41. The lifting mechanism 5 is used to make the annular spray pipe 41 slide along the central water supply pipe 4 or stop sliding.

[0035] Bottom valve mechanism 6 is installed on the shell 1 of the batching tank. Bottom valve mechanism 6 is used to block or unblock the discharge port.

[0036] like Figure 1 , Figure 4 As shown, the top of the mixing tank shell 1 has a through hole. The lifting mechanism 5 includes a vertically oriented lifting screw 51 that moves through the through hole. The bottom of the lifting screw 51 is fixedly connected to the top of the annular spray pipe 41. A threaded sleeve 52 is threaded onto the outside of the lifting screw 51, and the threaded sleeve 52 is rotatably connected to the top of the mixing tank shell 1. A lifting drive motor 53 is fixedly installed on the top of the mixing tank shell 1. The output shaft of the lifting drive motor 53 is connected to the threaded sleeve 52 through a bevel gear assembly 54. The bevel gear assembly 54 includes two meshing bevel gears. One bevel gear is coaxially fixedly connected to the output shaft of the lifting drive motor 53, and the other bevel gear is coaxially fixedly connected to the threaded sleeve 52. The lifting drive motor 53 drives the threaded sleeve 52 to rotate, converting the rotational motion into a precise and smooth linear lifting motion of the lifting screw 51. The threaded drive has self-locking properties, which allows the annular spray pipe 41 to stop at any required height and perform effective rinsing without sliding down due to water pressure or gravity.

[0037] like Figure 6 As shown, the bottom valve mechanism 6 includes a valve seat bracket 61 fixedly installed on the mixing tank shell 1. A valve plate 62, which can be attached to the bottom of the mixing tank shell 1, is hinged to the valve seat bracket 61 via a valve plate rotating shaft 621. When the valve plate 62 is attached to the bottom of the mixing tank shell 1, the valve plate 62 blocks the discharge port. A valve plate drive assembly 63 is installed on the valve seat bracket 61 to drive the valve plate rotating shaft 621 to rotate or stop rotating. The hinged valve plate 62 realizes the opening and closing of the discharge port, which is simple and reliable. When closed, it is attached to the bottom of the mixing tank shell 1 to block, and when opened, it opens the passage to facilitate discharge.

[0038] Furthermore, the valve plate drive assembly 63 includes a worm gear 631 coaxially fixed to the valve plate shaft 621. A worm 632 meshing with the worm gear 631 is rotatably mounted on the valve seat bracket 61. A handwheel is coaxially fixed to the end of the worm 632, and the transmission ratio of the worm gear and worm is 8:1. In use, the operator can rotate the handwheel to drive the worm 632 to rotate, thereby driving the valve plate shaft 621 to rotate on the valve seat bracket 61 through the worm gear 631. The operation is simple. Since the meshing of the worm gear 631 and the worm 632 has a self-locking property, the position of the valve plate shaft 621 can be fixed when the worm 632 is not rotated, which is convenient for use.

[0039] Furthermore, such as Figure 2 As shown, a sealing ring groove 622 is provided on the side of the valve plate 62 near the bottom of the mixing tank shell 1 and outside the discharge port. A sealing ring gasket 623 is inserted in the sealing ring groove 622 and engages with the valve plate 62. The sealing ring gasket 623 is made of rubber. When the valve plate 62 is in contact with the bottom of the mixing tank shell 1, the sealing ring gasket 623 abuts against the bottom of the mixing tank shell 1. Through the design of the sealing ring gasket 623, when the valve plate 62 is in contact with the bottom of the mixing tank shell 1 to block the discharge port, the sealing ring gasket 623 abuts against the bottom of the mixing tank shell 1, thereby increasing the fit between the valve plate 62 and the mixing tank shell 1 and increasing the sealing performance between the valve plate 62 and the mixing tank shell 1.

[0040] like Figure 1 As shown, an electric slip ring 7 is fixedly installed on the top of the mixing tank shell 1 and directly above the stirring shaft 2 via a bracket. The electric slip ring 7 is model DHS039-23. A connecting cavity 1 is opened on the top of the stirring shaft 2, and a connecting cavity 2 is opened on the stirring sleeve 3 in the middle. The connecting cavity 1 is connected to the driving cavity 31 through the connecting cavity 2. The electric slip ring 7 is connected to the linear actuator 34 wire via a wire. The other end of the electric slip ring 7 is connected to the external power supply cabinet via a connecting wire. The design of the electric slip ring 7 is such that when the stirring shaft 2 rotates on the tank cover 12, the electric slip ring 7 rotates with it, effectively avoiding the wire tangling caused by the rotation of the stirring shaft 2.

[0041] Furthermore, a feed hopper 8 connected to the feed inlet is fixedly installed on the top of the mixing tank shell 1. The design of the feed hopper 8 facilitates the addition of materials into the main tank 11 through the feed inlet. Multiple stirring rods 331 are fixedly installed on the side of the scraper plate 33 close to the stirring shaft 2 and below the multiple stirring sleeve rods 3. The design of multiple stirring rods 331 increases the stirring area of ​​the materials in the mixing tank shell 1 and improves the stirring effect.

[0042] like Figure 1 - Figure 3 As shown, the mixing tank shell 1 includes a main tank 11 with an open top. A tank cover 12 is rotatably mounted on the top of the outer side wall of the main tank 11. A driven bevel gear 13 is coaxially fixed to the outer side wall of the tank cover 12. A tank cover drive motor 14 is fixedly mounted on the main tank 11. The output shaft of the tank cover drive motor 14 is coaxially fixed to a drive bevel gear 15 that meshes with the driven bevel gear 13. During cleaning, the tank cover 12 can rotate relative to the main tank 11. During the cleaning process, the tank cover drive motor 14 is turned on, driving the drive bevel gear 15 to rotate. This causes the driven bevel gear 13 to drive the tank cover 12 to rotate on the main tank 11. The stirring drive motor is also turned on, causing the stirring shaft 2 to rotate in opposite directions between the tank cover 12 and the main tank 11. When the annular spray pipe 41 moves downward along the central water supply pipe 4, it can more thoroughly rinse the inner wall of the main tank 11 and the surfaces of the stirring shaft 2, stirring sleeve 3, scraper 33, and stirring rod 331, further improving the cleaning effect. Among them, the valve seat bracket 61 and the discharge port are located on the main tank 11, and the threaded sleeve 52, stirring shaft 2, stirring drive motor, bracket, lifting drive motor 53, central water supply pipe 4, and feed hopper 8 are all installed on the tank cover 12. This equipment is powered by an external power source. It is worth noting that the cleaning and lubrication cycle of each component of this equipment is set by the staff according to the application scenario, and the cleaning and lubrication methods of each component are existing technologies, which are known to those skilled in the art and will not be described in detail here.

[0043] Working principle and usage process of this utility model:

[0044] During installation, the main tank 11 is fixed to the external mounting bracket, so that there is a gap between the bottom of the main tank 11 and the ground, which does not affect the opening and closing of the valve plate 62 around the valve plate pivot 621;

[0045] During the mixing of raw materials, the raw materials are fed into the main tank 11 through the feed hopper 8 according to the proportion. After feeding, the stirring drive motor is turned on. The stirring drive motor drives the stirring shaft 2 to rotate on the tank cover 12 through bevel gear one and bevel gear two. Multiple stirring sleeve rods 3 rotate around the stirring shaft 2, thereby driving multiple stirring connecting rods 32 to rotate around the stirring shaft 2, which improves the mixing effect of the raw materials inside the main tank 11. During this process, the operator can control two linear actuators 34 through an external controller to make the two stirring connecting rods 32 located in the middle rotate along the two stirring sleeve rods 3. Sliding outwards from the drive cavity 31, both scraper blades 33 are in contact with the inner wall of the main tank 11. At this time, when multiple stirring rods 32 rotate around the stirring shaft 2, they drive both scraper blades 33 to rotate around the stirring shaft 2 to scrape and clean the inner wall of the main tank 11, effectively preventing the powder in the raw materials from adhering to the inner wall of the main tank 11 and affecting the mixing of the raw materials inside the main tank 11. Furthermore, when the scraper blades 33 rotate around the stirring shaft 2, they drive multiple stirring rods 331 to rotate around the stirring shaft 2, increasing the stirring area of ​​the materials in the mixing tank shell 1 and improving the stirring effect.

[0046] After the raw materials are mixed, the operator can rotate the handwheel to drive the worm gear 632 to rotate. The worm wheel 631 drives the valve plate shaft 621 to rotate on the valve seat bracket 61, so that the valve plate 62 rotates around the valve plate shaft 621 to remove the blockage of the discharge port, allowing the mixed raw materials in the main tank 11 to be discharged through the discharge port.

[0047] Based on the above technical concept, it can be understood that when cleaning the inside of the main tank 11, the two linear actuators 34 are controlled to move the stirring connecting rod 32 into the drive cavity 31, so that the two scraper plates 33 respectively fit with the stirring sleeve rods 3 located on both sides of the stirring shaft 2, and the external cleaning liquid delivery pump is controlled to deliver the cleaning liquid to the corrugated hose under high pressure, thereby delivering it to the annular spray pipe 41 through the central water supply pipe 4.

[0048] The cleaning solution is then discharged outward through multiple spray holes 42 on the outer and inner walls of the annular spray pipe 41, so that the cleaning solution is sprayed onto the inner wall of the main tank 11 and the surfaces of the stirring shaft 2, stirring sleeve 3, scraper 33 and stirring rod 331. At this time, the lifting drive motor 53 is turned on, and the threaded sleeve 52 is driven to rotate on the top of the tank cover 12 through the bevel gear assembly 54, so that the lifting screw 51 is moved downward along the perforation, which drives the annular spray pipe 41 to move downward, thereby achieving the effect of rinsing the inner wall of the main tank 11 and the surfaces of the stirring shaft 2, stirring sleeve 3, scraper 33 and stirring rod 331.

[0049] Instead of the existing method of injecting cleaning fluid into the main tank 11 and then rotating the stirring shaft 2 to drive the stirring blades, which in turn causes the cleaning fluid in the main tank 11 to flow and clean the inside of the mixing tank, the cleaning efficiency of the mixing tank is improved. During this process, the tank cover drive motor 14 is opened, which drives the active bevel gear 15 to rotate. This causes the driven bevel gear 13 to drive the tank cover 12 to rotate on the main tank 11. The stirring drive motor is also opened, causing the stirring shaft 2 to rotate in opposite directions on the tank cover 12. This allows the annular spray pipe 41 to move downward along the central water pipe 4, thus more thoroughly rinsing the inner wall of the main tank 11 and the surfaces of the stirring shaft 2, stirring sleeve 3, scraper 33, and stirring rod 331, further improving the cleaning effect.

[0050] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
