Description

Technical Field

[0001] This utility model relates to the field of oil storage technology, and in particular to a storage tank rotary jet agitator and its mixing and blending system. Background Technology

[0002] Liquid mixtures stored in tanks in industries such as petroleum, chemicals, wastewater treatment, food, and nuclear power often experience sedimentation at the bottom. The longer the storage time, the more sediment settles, leading to uneven liquid composition, substandard quality, raw material loss, and reduced tank capacity. Furthermore, the sediment at the bottom can undergo qualitative changes over time, affecting the overall quality of the liquid mixture. In some tanks with heating coils, sediment covering the coils can prevent heat dissipation, resulting in inadequate heating and even coking.

[0003] To address the issue of sediment settling in storage tanks, methods typically involve periodic tank shutdowns for manual cleaning or the installation of agitators. However, manual cleaning is time-consuming, labor-intensive, and costly. Discarding the settled material after cleaning is wasteful and can also pollute the environment. While rotary jet agitators are available, their impeller shaft directly transmits power to the worm gear, which in turn drives the worm wheel. This design results in excessively high rotational speeds for the worm gear and worm, leading to wear and a limited lifespan. Utility Model Content

[0004] This invention aims to provide a tank rotary jet agitator and a mixing and blending system, which reduces the speed of the first set of worm gears, reduces wear, extends service life, and effectively solves the problem of settling to the bottom.

[0005] To achieve the above objectives, the present invention provides the following technical solution: It includes a housing, a box, and a transmission assembly. The housing contains a sealed box, and the remaining parts of the housing form a vertically penetrating channel. The transmission assembly is installed within the box. It also includes an impeller and a main shaft. The lower end of the main shaft is connected to the impeller, and the upper end of the main shaft extends into the sealed box and is installed and meshed with the transmission assembly. The liquid mixture drives the impeller and the main shaft to rotate, and the main shaft drives the transmission assembly to rotate. Furthermore, it includes a cover and a nozzle. The transmission assembly meshes with the cover, and the transmission assembly drives the cover to rotate. It also includes a nozzle, with at least two nozzles symmetrically mounted on the cover. The cover drives the nozzles to rotate, and the liquid mixture flows through the channel and is ejected from the nozzles. The transmission assembly includes a first gear, a first worm, and a second gear. The first gear is mounted on the main shaft, the first worm is vertically arranged, and the second gear is mounted on the first worm. The first gear and the second gear mesh.

[0006] In a preferred embodiment of the present invention, the transmission assembly further includes a transmission rod, which is connected to the first worm gear, and a third gear is provided at the top of the transmission rod, which meshes with the cover.

[0007] In a preferred embodiment of this utility model, the cover includes a housing and an internal gear. The internal gear is fixed on the housing, and the third gear meshes with the internal gear, thereby driving the housing to rotate.

[0008] In a preferred embodiment of this utility model, the transmission assembly further includes a second worm, a third worm, a first worm wheel, a second worm wheel, and a third worm wheel. The second worm is horizontally arranged and perpendicular to the first worm, the third worm is horizontally arranged and perpendicular to the second worm, and the transmission rod is vertically arranged and perpendicular to the third worm. The first worm wheel is mounted on the second worm and meshes with it. The second worm wheel is mounted on the third worm and meshes with it.

[0009] In a preferred embodiment of this utility model, the cover includes a main gear and a second bearing. The main gear is fixedly installed inside the cover, and the second bearing is installed between the main gear and the cover. When the cover rotates, the main gear remains stationary.

[0010] In a preferred embodiment of the present invention, the cover further includes a second sealing element, which is fitted onto the second bearing.

[0011] In a preferred embodiment of this utility model, the nozzle is meshed with the main gear.

[0012] In a preferred embodiment of the present invention, the nozzle includes a spray pipe, a rotating gear, and a spray port. One end of the spray pipe is connected to the rotating gear, which is located inside the housing and meshes with the main gear. The other end of the spray pipe is connected to the spray port. The spray pipe is bent to form a bent section, and the spray port is installed on the bent section.

[0013] In a preferred embodiment of the present invention, the rotary jet agitator further includes a sealing assembly, which is fitted onto the main shaft. The sealing assembly includes a mechanical seal and a first bearing. The mechanical seal is fitted onto a section between the impeller and the housing, and the first bearing is fitted onto a section of the main shaft that passes through the housing.

[0014] In a preferred embodiment of the present invention, the rotary jet mixer further includes a housing, and the box is disposed inside the housing, forming a sealed space separated by the housing, with other areas inside the housing being open to each other.

[0025] To make the objectives and technical solutions of the present utility model embodiments clearer, the following will be described in conjunction with the accompanying drawings of the present utility model embodiments. Figure 1 -Appendix Figure 5 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] like Figure 1 As shown, a tank rotary jet agitator 1 includes a housing 11 and a flange 12. The flange 12 is provided at the lower end of the housing 11 and is used to connect the housing 11 to other components.

[0027] like Figure 2 As shown, the rotary jet mixer 1 also includes a housing 13 and a transmission assembly 14. The housing 13 is a sealed space separately separated within the shell 11. The other parts of the shell 11 are vertically connected channels through which the liquid mixture flows. The transmission assembly 14 is installed inside the housing 13.

[0028] like Figure 2 As shown, the rotary jet mixer 1 also includes a main shaft 15 and an impeller 16. The upper end of the main shaft 15 extends into the housing 13 and is installed therein. The main shaft 15 is meshed with the transmission assembly 14. The impeller 16 is fixedly installed at the lower end of the main shaft 15, and the impeller 16 drives the main shaft 15 to rotate. The liquid mixture pushes the impeller 16 to rotate, and the main shaft 15 follows the rotation of the impeller 16. The main shaft 15 then transmits power to the transmission assembly 14.

[0029] like Figure 2 As shown, the rotary jet agitator 1 also includes a sealing assembly 17, which is mounted on the main shaft 15 and located above the impeller 16. The sealing assembly 17 is used to prevent the liquid mixture from entering the transmission assembly 14 along the main shaft 15 and affecting the operation of the transmission assembly 14.

[0030] like Figure 1 As shown, the rotary jet agitator 1 further includes a cover 18 and nozzles 19. The cover 18 is rotatably connected to the housing 11, and at least two nozzles 19 are rotatably mounted on the cover 18. Multiple nozzles 19 are symmetrically arranged, such as... Figure 2 As shown, the cover 18 is engaged with the nozzle 19, and the transmission assembly 14 is engaged with the cover 18. The transmission assembly 14 drives the cover 18 to rotate, and the cover 18 drives the nozzle 19 to rotate.

[0031] like Figure 2 As shown, the transmission assembly 14 includes a first gear 141, a first worm gear 142, and a second gear 143. The first gear 141 is mounted on the main shaft 15, as shown. Figure 3 As shown, the first worm gear 142 is vertically installed inside the housing 13. The threaded teeth of the first worm gear 142 are provided on the upper end of the first worm gear 142. The second gear 143 is mounted on the first worm gear 142, and the second gear 143 and the first gear 141 are meshed and connected.

[0032] like Figure 3 As shown, the transmission assembly 14 further includes a second worm 144 and a first worm wheel 145. The second worm 144 is horizontally installed inside the housing 13 and is perpendicular to the first worm 142. One end of the second worm 144 is fitted with the first worm wheel 145, and the other end of the second worm 144 is provided with threaded teeth. The first worm wheel 145 is meshed with the first worm 142, and the first worm wheel 145 and the first worm 142 form a worm gear structure.

[0033] like Figure 3 As shown, the transmission assembly 14 further includes a third worm 146 and a second worm wheel 147. The third worm 146 is horizontally installed inside the housing 13 and is perpendicular to the second worm 144. One end of the third worm 146 is fitted with the second worm wheel 147, and the other end of the third worm 146 is provided with threaded teeth. The second worm wheel 147 is meshed with the second worm 144, and the second worm wheel 147 and the second worm 144 form a worm gear structure.

[0034] like Figure 3 As shown, the transmission assembly 14 also includes a transmission rod 148 and a third worm gear 149. The transmission rod 148 is vertically installed inside the housing 13. The top of the transmission rod 148 extends out of the housing 13 and engages with the cover 18. The third worm gear 149 is fitted on the transmission rod 148. The third worm gear 149 engages with the third worm 146. The third worm 146 and the third worm gear 149 form a worm gear structure.

[0035] Specifically, the top of the transmission rod 148 is gear-shaped, designated as the third gear 1481, as shown below. Figure 2 As shown, the third gear 1481 is meshed with the cover 18.

[0036] Furthermore, the main shaft 15 extends into and is installed in the housing 13. Compared to the traditional main shaft 15, it is longer and can be used in larger storage tanks 2. The main shaft 15 also has better stability. At the same time, the transmission assembly 14 adds a set of gears, the first gear 141 and the second gear 143, for initial speed reduction, making the rotational speed of the entire worm gear structure slower and improving the service life of the worm gear structure. In addition, the first gear 141 and the second gear 143 prevent the main shaft 15 from directly driving the first worm 142, preventing the first worm 142 and the first worm wheel 145 from directly driving at too high a speed and reducing wear.

[0037] like Figure 2 As shown, the sealing assembly 17 includes a mechanical seal 171, a first bearing 172, and a first sealing element 173. The mechanical seal 171 and the first bearing 172 are sleeved on the lower end of the main shaft 15. The mechanical seal 171 is sleeved on a section between the impeller 16 and the housing 13. The first bearing 172 is sleeved on a section of the main shaft 15 that passes through the housing 13. The first sealing element 173 is sleeved on the first bearing 172. The mechanical seal 171 and the first sealing element 173 are used to seal the housing 13, preventing liquid mixtures from entering the housing 13 along the main shaft 15. The first bearing 172 is used to assist the rotation of the main shaft 15.

[0038] like Figure 2 As shown, the cover 18 includes a housing 181 and an internal gear 182. The internal gear 182 is fixedly mounted on the bottom of the housing 181, as shown. Figure 3 As shown, the internal gear 182 is meshed with the third gear 1481. The rotation of the third gear 1481 drives the internal gear 18 to rotate, and the internal gear 182 drives the entire cover 181 to rotate.

[0039] like Figure 2 As shown, the cover 18 also includes a main gear 183, a second bearing 184, and a second seal 185. The main gear 183 is positioned above the internal gear 182. The second bearing 184 is disposed between the main gear 183 and the cover 181, supporting rotational movement. The second seal 185 is fitted onto the second bearing 184. The main gear 183 meshes with the nozzle 19. The main gear 183 does not rotate, but the cover 181 rotates. The rotation of the cover 181 drives the nozzle 19 to rotate. Figure 4 As shown, the nozzle 19 is meshed with the internal gear 182, and the nozzle 19 rotates along the internal gear 182.

[0040] like Figure 4 As shown, the nozzle 19 includes a spray pipe 191, a rotating gear 192, and a spray port 193. The spray pipe 191 extends out of the housing 181. One end of the spray pipe 191 is connected to the rotating gear 192, which is located inside the housing 181. The other end of the spray pipe 191 is connected to the spray port 193. The spray pipe 191 is bent to form a bent section, and the spray port 193 is mounted on the bent section. Driven by the rotation of the housing 181, the rotating gear 192 meshes with the main gear 183, causing the nozzle 19 to rotate in a circle, thus increasing the spray range and improving the stirring effect.

[0041] Specifically, the main gear 183 and the rotating gear 192 are precision-cast, non-equidistant sawtooth gears. If there are particles or impurities in the liquid mixture, it will not affect the main gear 183 and the rotating gear 192, making it suitable for complex scenarios. However, if gears with smaller tooth pitch are used, impurities or particles in the liquid mixture can easily get stuck between the teeth, causing the gears to fail to mesh properly and the rotary agitator 1 to malfunction.

[0042] like Figure 5 As shown, this utility model also provides a stirring and blending system, including the rotary jet mixer 1. The stirring and blending system also includes a storage tank 2, a circulation pipe 3, and a circulation pump 4. The rotary jet mixer 1 is installed in the storage tank 2. The storage tank 2 is connected to the circulation pipe 3. One end of the circulation pipe 3 extends into the storage tank 2, and the rotary jet mixer 1 is installed on that end. The other end of the circulation pipe 3 is connected to the storage tank 2. Multiple circulation pumps 4 are connected to the circulation pipe 3. The circulation pumps 4 are used to make the liquid mixture in the storage tank 2 flow along the circulation pipe 3 and pump the liquid mixture into the rotary jet mixer 1. The rotary jet mixer 1 stirs the liquid mixture in the storage tank 2.

[0043] Specifically, the specific structure of the circulation pipe 3 is known to those skilled in the art and will not be described in detail here.

[0044] The specific working process of the rotary jet agitator 1 in the mixing and blending system is as follows: The circulation pump 4 pumps the liquid mixture in the storage tank 2 into the circulation pipe 3 and flows along the circulation pipe 3. After the liquid mixture is pumped into the rotary jet agitator 1, the impeller 16 rotates under the impact of the liquid mixture. The main shaft 15 transmits the rotation to the transmission assembly 14. After the transmission assembly 14 decelerates, it drives the internal gear 182 to rotate. The internal gear 182 drives the cover 181 to rotate. The cover 181 rotates with the nozzle 19 installed on the cover 181. Further, the rotating gear 192 meshes with the main gear 183 and rotates. The nozzle 19 rotates in a circle. The liquid mixture flows from the housing 11 into the cover 18 and is sprayed out from the nozzle 19, stirring the liquid mixture in the storage tank 2.

[0045] The specific working process of the transmission assembly 14 is as follows. Since the helical directions of the helical teeth of the first worm 142, the second worm 144, and the third worm 146 are not specified, the rotation direction will not be specifically described in the following description; only the transmission process will be explained. The main shaft 15 drives the first gear 141 to rotate, the first gear 141 drives the second gear 143 to rotate, and the second gear 143 rotates synchronously with the first worm 142. The helical teeth of the first worm 142 drive the first worm wheel 143 to rotate, and the first worm wheel 143 rotates synchronously with the second worm 144. The helical teeth of the second worm 144 drive the second worm wheel 147 to rotate, and the second worm wheel 147 rotates synchronously with the third worm 146. The helical teeth of the third worm 146 drive the third worm wheel 149 to rotate, and the third worm wheel 149 rotates synchronously with the transmission shaft 148. The third gear 1481 at the upper end of the transmission shaft 148 meshes and rotates with the internal gear 182, and the internal gear 182 drives the cover 18 to rotate.

[0046] This utility model provides a tank rotary jet agitator that adds a reduction stage through the first and second gears, lowering the speed of the first worm gear. This avoids the problem of excessively high worm gear speed and easy wear caused by direct transmission between the first worm gear and the main shaft, thus extending its service life. Furthermore, by replacing the main gear and rotating gear with large-clearance sawtooth gears, it effectively avoids jamming caused by particles or impurities in the liquid mixture blocking the tooth gaps, making the transmission more reliable. The mixing and blending system including this tank rotary jet agitator can more thoroughly agitate the liquid mixture in the tank, effectively solving the problem of sedimentation and improving the utilization rate of the liquid mixture.

[0047] Although the present invention has been disclosed above by way of embodiments, it is not intended to limit the present invention. Anyone skilled in the art can make some modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
