Description

Technical Field

[0001] This application relates to the field of mixing equipment technology, and in particular to a tank mixing device. Background Technology

[0002] Currently, in coal chemical ash water tanks, ash water settling tanks, wet desulfurization towers, and other storage tanks, there are no mixing facilities, or the mixing facilities are improperly located, causing bottom material to accumulate and block the material inlet pipeline. The bottom material is not fully mixed, resulting in insufficient inlet suction of the material conveying pump, which in severe cases affects the normal material conveying, causing material overflow or other accidents. In addition, some storage tanks have small volumes, so the investment in installing a mixer is large and the operation and maintenance costs are high. Side-drainage mixers with openings in the side wall of the storage tank are selected, which are very prone to material leakage at the rotating parts. Utility Model Content

[0003] This application aims to solve at least one of the technical problems existing in the prior art. To this end, this application proposes a tank stirring device that enables convection and circumferential rotation of materials inside the tank, achieving an all-round stirring effect, effectively removing sediment from the tank, and reducing stirring costs.

[0004] This application provides a storage tank stirring device, including: a storage tank, an annular disturbance pipeline, a first material conveying pipeline, a second material conveying pipeline, a material circulation pipeline, a circulating liquid pump, and multiple sinking jet mechanisms;

[0005] The annular disturbance pipeline and the plurality of the sinking injection mechanisms are all located inside the storage tank, and the annular disturbance pipeline and the plurality of the sinking injection mechanisms are all located near the bottom of the storage tank. The plurality of the sinking injection mechanisms are evenly distributed at the bottom of the annular disturbance pipeline, and each of the sinking injection mechanisms is connected to the annular disturbance pipeline.

[0006] One end of the first material conveying pipeline is connected to the input end of the circulating liquid pump, and the other end of the first material conveying pipeline passes through the side wall of the storage tank. The first material conveying pipeline is located near the bottom of the side wall of the storage tank. One end of the second material conveying pipeline is connected to the output end of the circulating liquid pump. The material circulation pipeline is connected to the second material conveying pipeline, and the connection between the material circulation pipeline and the second material conveying pipeline is located near the other end of the second material conveying pipeline. The diameter of the material circulation pipeline is smaller than the diameter of the first material conveying pipeline. The end of the material circulation pipeline away from the second material conveying pipeline extends into the interior of the first material conveying pipeline and connects to the annular disturbance pipeline.

[0007] The circulating fluid pump is used to pressurize the material in the storage tank so that the material delivered to the second material conveying pipeline is transported from the material circulation pipeline to the annular disturbance pipeline and sprayed out through the multiple sinking injection mechanisms connected to the annular disturbance pipeline.

[0008] According to some embodiments of this application, each of the sinking injection mechanisms includes a connecting pipeline and a sinking nozzle assembly. The connecting pipeline corresponds one-to-one with the sinking nozzle assembly. One end of each connecting pipeline is connected to the annular disturbance pipeline, and the other end of each connecting pipeline is connected to the corresponding sinking nozzle assembly.

[0009] According to some embodiments of this application, the submerged nozzle assembly includes two submerged nozzles, both of which are connected to the corresponding connecting pipeline.

[0010] According to some embodiments of this application, flow-limiting orifice plates are respectively provided in the connecting pipeline near the two sinking nozzles.

[0011] According to some embodiments of this application, the tank stirring device further includes a first material control valve, which is located on the material circulation pipeline.

[0012] According to some embodiments of this application, the tank stirring device further includes a second material control valve, which is located on the first material conveying pipeline and is positioned close to the circulating liquid pump.

[0013] According to some embodiments of this application, the tank stirring device further includes a third material control valve, which is located on the second material conveying pipeline, and the connection between the material circulation pipeline and the second material conveying pipeline is located between the third material control valve and the circulating liquid pump.

[0014] According to some embodiments of this application, the side wall of the storage tank is provided with a port corresponding to the first material conveying pipeline near the bottom, and the first material conveying pipeline is connected to the storage tank through the port.

[0015] The beneficial effects of this application are reflected in the fact that the circulating liquid pump is used to pump the material in the storage tank through the first material conveying pipeline to the second material conveying pipeline, and from the second material conveying pipeline to the next process. The circulating liquid pump is also used to pressurize the material in the storage tank so that the material conveyed to the second material conveying pipeline is conveyed from the material circulation pipeline to the annular disturbance pipeline, and is ejected through multiple sinking spray mechanisms connected to the annular disturbance pipeline. The sinking spray mechanisms are arranged in a ring, and the material ejected by the sinking spray mechanisms washes and breaks up the storage tank within a certain range. The material circulation system effectively removes sediment accumulated at the bottom of the tank, causing convection and circumferential rotation within the tank, resulting in comprehensive agitation. The material is then discharged through a first and a second material conveying pipeline, thus effectively removing the sediment. The output end of the material circulation pipeline is fitted inside the first material conveying pipeline, preventing tank wall degradation due to re-opening the side wall or material leakage due to welding quality issues. Furthermore, using the existing material conveying pump as the circulating fluid pump saves electricity and reduces costs compared to using an agitator. This design enables convection and circumferential rotation of the material within the tank, achieving comprehensive agitation and effectively removing sediment while reducing agitation costs.

[0026] Currently, in coal chemical ash water tanks, ash water settling tanks, wet desulfurization towers, and other storage tanks, there are no mixing facilities, or the mixing facilities are improperly located, causing bottom material to accumulate and block the material inlet pipeline. The bottom material is not fully mixed, resulting in insufficient inlet suction of the material conveying pump, which in severe cases affects the normal material conveying, causing material overflow or other accidents. In addition, some storage tanks have small volumes, so the investment in installing a mixer is large and the operation and maintenance costs are high. Side-drainage mixers with openings in the side wall of the storage tank are selected, which are very prone to material leakage at the rotating parts.

[0027] To address the aforementioned problems, this application proposes a tank stirring device. The embodiments of this application will be further described below with reference to the accompanying drawings.

[0028] Reference Figure 1This application provides a tank stirring device, including a tank 100, an annular disturbance pipeline 110, a first material conveying pipeline 210, a second material conveying pipeline 220, a material circulation pipeline 230, a circulating liquid pump 200, and multiple submerged jetting mechanisms. The annular disturbance pipeline 110 and the multiple submerged jetting mechanisms are all located inside the tank 100, and are positioned close to the bottom of the tank 100. The multiple submerged jetting mechanisms are evenly distributed at the bottom of the annular disturbance pipeline 110, and each submerged jetting mechanism is connected to the annular disturbance pipeline 110. One end of the first material conveying pipeline 210 is connected to the input end of the circulating liquid pump 200, and the other end of the first material conveying pipeline 210 passes through the side wall of the tank 100, with the first material conveying pipeline 210 positioned close to the bottom of the side wall of the tank 100. The system is configured such that one end of the second material conveying pipeline 220 is connected to the output end of the circulating liquid pump 200, and the material circulation pipeline 230 is connected to the second material conveying pipeline 220. The connection point of the material circulation pipeline 230 and the second material conveying pipeline 220 is located near the other end of the second material conveying pipeline 220. The diameter of the material circulation pipeline 230 is smaller than the diameter of the first material conveying pipeline 210. The end of the material circulation pipeline 230 away from the second material conveying pipeline 220 extends into the interior of the first material conveying pipeline 210 and connects to the annular disturbance pipeline 110. The circulating liquid pump 200 is used to pressurize the material in the storage tank 100 so that the material conveyed to the second material conveying pipeline 220 is conveyed from the material circulation pipeline 230 to the annular disturbance pipeline 110 and sprayed out through multiple sinking injection mechanisms connected to the annular disturbance pipeline 110.

[0029] In this embodiment, four sinking jet mechanisms are provided. In other embodiments, other numbers of sinking jet mechanisms may be provided according to the stirring effect required by the storage tank 100, and are not limited to the embodiments of this application.

[0030] In this application, the circulating liquid pump 200 is used to pump the material in the storage tank 100 through the first material conveying pipeline 210 to the second material conveying pipeline 220, and then from the second material conveying pipeline 220 to the next process. The circulating liquid pump 200 is also used to pressurize the material in the storage tank 100 so that the material conveyed to the second material conveying pipeline 220 is conveyed from the material circulation pipeline 230 to the annular disturbance pipeline 110, and sprayed out through multiple sinking spray mechanisms connected to the annular disturbance pipeline 110. The sinking spray mechanisms are arranged in a ring, and the material sprayed by the sinking spray mechanisms washes and breaks up the storage tank 100 within a certain range. The sediment accumulated at the bottom of tank 100 is stirred up by convection, creating a circumferential rotational motion within the tank, thus achieving a comprehensive stirring effect. The material is then discharged through the first material conveying pipeline 210 and the second material conveying pipeline 220, effectively removing the sediment from storage tank 100. The output end of the material circulation pipeline 230 is fitted inside the first material conveying pipeline 210, avoiding the risk of tank wall degradation due to re-opening the side wall of storage tank 100 or material leakage due to welding quality issues. Furthermore, using the existing material conveying pump as the circulating liquid pump 200 saves electricity and reduces costs compared to using an agitator. This design enables convection and circumferential rotation of the material within the tank, achieving a comprehensive stirring effect to effectively remove sediment from storage tank 100 while reducing stirring costs.

[0031] Reference Figure 1 It is understood that each sinking injection mechanism includes a connecting line 120 and a sinking nozzle 130 assembly. The connecting line 120 corresponds one-to-one with the sinking nozzle 130 assembly. One end of each connecting line 120 is connected to the annular disturbance line 110, and the other end of each connecting line 120 is connected to the corresponding sinking nozzle 130 assembly.

[0032] Reference Figure 1 It is understood that the submerged nozzle 130 assembly includes two submerged nozzles 130, both of which are connected to the corresponding connecting line 120.

[0033] In some embodiments, other numbers of submerged jet mechanisms and other numbers of submerged nozzles 130 may be selected to be provided according to the stirring effect required by the storage tank 100, and are not limited to the embodiments of this application.

[0034] It is understandable that flow-limiting orifice plates are installed in the connecting pipeline 120 near the two submerged nozzles 130.

[0035] In some embodiments, the connecting line 120 includes a first line and a second line corresponding to each of the two submerged nozzles 130. The number of the second lines corresponds to the number of the submerged nozzles 130. One end of the first line is connected to the annular disturbance line 110, and the other end of the first line is connected to the input ends of the two second lines respectively. The output end of the second line is connected to the corresponding submerged nozzle 130.

[0036] In some embodiments, the number of flow-limiting orifice plates corresponds to the number of second pipelines. The flow-limiting orifice plates are set in the corresponding second pipelines. By setting the flow-limiting orifice plates, it is ensured that the pressure and flow rate delivered to each submerged nozzle 130 are equivalent, preventing the accumulation of material on the side of the bottom sediment. Under the action of the liquid sprayed by the submerged nozzle 130, the sediment at the bottom of the tank is fully flushed and broken up. The stirring intensity of the entire storage tank 100 is basically consistent, leaving no dead corners, and the stirring effect is good.

[0037] Reference Figure 1 It is understood that the tank stirring device also includes a first material control valve 231, which is located on the material circulation pipeline 230.

[0038] It should be noted that by setting the first material control valve 231, the first material control valve 231 can be opened when it is necessary to stir the sediment at the bottom of the storage tank 100, and closed when it is not necessary to stir the sediment at the bottom of the storage tank 100. The intensity of stirring the sediment at the bottom of the storage tank 100 can also be determined by controlling the opening degree of the first material control valve 231.

[0039] Reference Figure 1 It is understood that the tank stirring device also includes a second material control valve 211, which is located on the first material conveying pipeline 210 and is located near the circulating liquid pump 200.

[0040] Reference Figure 1 It is understood that the tank stirring device also includes a third material control valve 221, which is located on the second material conveying pipeline 220, and the connection between the material circulation pipeline 230 and the second material conveying pipeline 220 is located between the third material control valve 221 and the circulating liquid pump 200.

[0041] It should be noted that the opening and closing of the second material control valve 211 and the third material control valve 221 are used to control whether the circulating liquid pump 200 pumps material from the storage tank 100.

[0042] It is understandable that the storage tank 100 has a pipe opening near the bottom on its side wall, which corresponds to the first material conveying pipeline 210. The first material conveying pipeline 210 is connected to the storage tank 100 through the pipe opening.
