Description

Technical Field

[0001] This utility model relates to the field of dispersion tank technology, specifically a dispersion tank for loading chemical materials. Background Technology

[0002] In chemical production processes, materials such as powders, liquids, or slurries typically require temporary storage and handling in containers during loading, mixing, and transportation. Existing chemical dispersion containers often feature mechanical stirring blades or simple rotary stirring devices inside the container. A motor drives the blades to rotate, creating a stirring flow field in a localized area to achieve mixing and dispersion of the material.

[0003] However, traditional stirring structures have significant shortcomings in practical applications: First, mechanical paddle stirring is a localized agitation with a limited flow field, which can easily lead to material deposition at the bottom of the tank and uneven mixing between upper and lower layers, making it difficult to meet the high requirements for uniform material dispersion; second, the shear force driven by the paddles is relatively singular, resulting in poor dispersion for materials with high viscosity or a large number of particles; third, some dispersion tanks only have a single outlet, requiring gravity flow for material discharge, which results in low operating efficiency and makes it impossible to switch flow paths when cyclic mixing and dispersion are required.

[0004] In addition, most existing dispersion tanks adopt a fixed inlet or outlet structure, lacking flexible flow control, and cannot achieve material circulation and directional discharge according to process requirements; at the same time, some mixing tanks fail to form multi-point dispersion flow inside the tank, resulting in more dead zones in the mixing, longer dispersion time, and higher energy consumption.

[0005] In summary, existing chemical dispersion tanks have shortcomings in terms of material mixing uniformity, flow direction switching flexibility, and discharge convenience. Therefore, there is an urgent need to provide a chemical material loading dispersion tank with a rationally improved structure, capable of forming multi-point dispersion flow within the tank, and enabling switching between circulating mixing and directional discharge, in order to solve the aforementioned problems in the existing technology. Utility Model Content

[0006] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0007] Therefore, the technical solution adopted by this utility model is as follows: a dispersion tank for loading chemical materials, including a main tank body, a cap, a liquid outlet valve head, a centrifugal pump unit, and a stirring rod. The centrifugal pump unit drives material circulation, and in conjunction with the flow direction switching of the reversing valve and the dispersion effect of the stirring rod, rapid and uniform mixing and multi-mode discharge of materials within the tank are achieved. The centrifugal pump unit is installed at the bottom of the main tank body cavity and includes a pump casing, a motor, and a centrifugal impeller; the bottom surface of the pump casing has several liquid inlet grooves, and the surface of the pump casing has a liquid outlet port. The centrifugal impeller is rotatably installed inside the pump casing and connected to the motor for drive.

[0008] Specifically, this structure allows material at the bottom of the barrel to smoothly enter the pump casing and be accelerated out by the impeller, ensuring continuous circulation of the material and improving dispersion efficiency.

[0009] In a preferred example, the outlet port is connected to a reversing valve, and the reversing valve is connected to the outlet valve head and the agitator.

[0010] Specifically, this design allows for flexible switching of material flow paths, enabling both external discharge and return to the agitator for secondary dispersion, resulting in more diverse operating modes.

[0011] In a preferred example, a cap is installed at the upper port of the main barrel, and the cap is detachable for opening or closing the barrel.

[0012] Specifically, the design ensures ease of loading and cleaning, while maintaining a sealed barrel during operation to prevent material spillage.

[0013] In a preferred embodiment, the discharge valve head is located on the bottom outer side of the main tank and is connected to the discharge port of the centrifugal pump unit via a reversing valve.

[0014] Specifically, this structure allows materials to be discharged quickly according to process requirements, simplifying operation and improving discharge efficiency.

[0015] In a preferred example, the liquid inlet grooves are arranged uniformly in a circumferential direction and are flush with the bottom surface of the inner cavity of the main tank.

[0016] Specifically, this design ensures that the material at the bottom of the tank can enter the pump unit evenly, avoiding material sedimentation and blockage, and improving suction efficiency.

[0017] In a preferred example, the motor is fixedly installed inside the centrifugal pump assembly to drive the centrifugal impeller to rotate.

[0018] Specifically, the structure provides a stable power source, enabling materials to maintain continuous flow and dispersion during the circulation process.

[0019] In a preferred example, the agitator is vertically arranged inside the main tank and connected to the centrifugal pump unit through a reversing valve. Multiple convection holes are evenly distributed on the agitator along the height direction.

[0020] Specifically, this structure creates a multi-point jet flow when the material passes through the agitator, causing the fluid inside the barrel to form a uniform, dispersed, circulating flow field, thereby achieving efficient mixing of the material.

[0021] The beneficial effects achieved by this utility model are as follows:

[0022] 1. In this invention, a centrifugal pump unit is installed at the bottom of the main tank. A motor drives the centrifugal impeller to rotate, causing the material inside the tank to enter the pump casing through the inlet tank and be discharged through the outlet port. The flow direction is then switched via a reversing valve, allowing the material to be directed either to the outlet valve head for directional discharge or to the agitator for internal circulation and dispersion. The agitator has multiple convection holes evenly distributed along its height. When material is ejected through the agitator, it creates a multi-point dispersion flow field within the tank, effectively enhancing convection and mixing, and significantly improving the dispersion efficiency and uniformity of the material.

[0023] 2. In this invention, the reversing valve can flexibly switch the flow direction to meet different operational needs; the outlet valve head enables convenient discharge of materials outside the container. Through the above structural design, this invention not only improves the efficiency and reliability of mixing and dispersion, but also simplifies the operation process, has strong adaptability, and has good industrial application value.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0032] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0033] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a dispersion tank for loading chemical materials.

[0034] Combination Figures 1-4 As shown, the present invention provides a dispersion tank for loading chemical materials, including a main tank body 100, a cover 110, a liquid outlet valve head 200, a centrifugal pump set 300, and a stirring rod 400.

[0035] The main tank 100 has a cylindrical structure and is equipped with multiple casters at the bottom for easy movement in different locations. The upper end of the main tank 100 can be sealed with a cover 110, which has a detachable installation structure for easy loading or cleaning.

[0036] The centrifugal pump assembly 300 is installed at the bottom of the inner cavity of the main tank 100. The centrifugal pump assembly 300 includes a pump casing 310, a motor 320, and a centrifugal impeller 330. Several inlet grooves 311 are evenly distributed on the bottom surface of the pump casing 310, flush with the bottom surface of the inner cavity of the main tank 100, to ensure that materials inside the tank can smoothly enter the pump casing 310. An outlet port 312 is provided on the outer wall of the pump casing 310, connected to a reversing valve 420. The centrifugal impeller 330 is rotatably mounted inside the pump casing 310 and is connected to the motor 320 for drive. When the motor 320 operates, it drives the centrifugal impeller 330 to rotate, thereby creating a suction and discharge effect.

[0037] The reversing valve 420 is installed on the outside of the liquid outlet port 312. The input end of the reversing valve 420 is connected to the liquid outlet port 312, and its output end is connected to the liquid outlet valve head 200 on one hand for external discharge; on the other hand, it is connected to the agitator bar 400 for secondary material circulation. The liquid outlet valve head 200 is fixedly installed on the bottom outside of the main tank 100, and the directional discharge of material is achieved by opening and closing the valve.

[0038] The stirring bar 400 is vertically arranged inside the main tank 100. The bottom of the stirring bar 400 is connected to the reversing valve 420, thereby receiving the fluid output from the centrifugal pump unit 300. Multiple convection holes 410 are evenly distributed along the height direction on the stirring bar 400. When material enters the stirring bar 400 under pumping pressure, it can be ejected through the convection holes 410, forming a multi-point dispersion flow arranged vertically, promoting the circulation and convection of material inside the tank, and enhancing the dispersion and mixing effect.

[0039] In this embodiment, the cover 110 has a screw-on or snap-on structure, which can achieve quick opening and sealing closure; the liquid inlet trough 311 is arranged in a ring and evenly distributed, so as to ensure that the material is not easily blocked when entering the centrifugal pump set 300; the motor 320 is fixed to the outer wall of the pump casing 310 and adopts a protective sealing structure to ensure long-term operational stability; the diameter and spacing of the convection holes 410 can be adjusted according to the viscosity of the material so as to form an ideal dispersed flow field under different material conditions.

[0040] In the operation of this embodiment, the chemical material to be dispersed is first added into the main tank 100, and the upper port is sealed by the cap 110. When the motor 320 drives the centrifugal impeller 330 to rotate, the material in the tank enters the pump casing 310 through the inlet tank 311 and is discharged through the outlet port 312 under the action of centrifugal force. By adjusting the reversing valve 420, the material can be discharged directly out of the tank through the outlet valve head 200, or it can enter the tank again for recirculation through the agitator 400. When the material flows through the agitator 400, it is sprayed out from multiple points through the convection holes 410, which promotes the dispersion and mixing of the fluid in the tank, thereby achieving rapid and uniform dispersion of the chemical material.

[0041] In summary, this invention achieves rapid mixing and dispersion of materials within the container through the power circulation of the centrifugal pump unit 300, the flow direction switching of the reversing valve 420, and the multi-point dispersion effect of the agitator 400. It also allows for the discharge of materials outside the container as needed, offering flexible operation and strong applicability. This structural design not only improves dispersion efficiency and mixing uniformity but also simplifies the operation process, demonstrating significant practical value.

[0042] Working principle and usage process of this utility model:

[0043] This utility model discloses a dispersion tank for loading chemical materials. In use, the chemical materials to be processed are first loaded into the main tank body 100, and the tank opening is sealed by the cap 110 to prevent material leakage.

[0044] When it is necessary to disperse and agitate the material inside the barrel, the centrifugal pump unit 300 is started. The centrifugal pump unit 300 is installed at the bottom of the inner cavity of the main barrel 100, and its pump casing 310 has several inlet grooves 311 on its bottom surface. The inlet grooves 311 are flush with the bottom surface of the inner cavity of the main barrel 100 to ensure that the material inside the barrel can smoothly enter the pump casing 310. Driven by the motor 320, the centrifugal impeller 330 rotates at high speed, generating a negative pressure suction effect, which causes the material inside the barrel to be sucked into the pump casing 310 through the inlet grooves 311.

[0045] The sucked-in material is discharged along the liquid outlet port 312 under the action of centrifugal force and enters the reversing valve 420 connected thereto. By adjusting the reversing valve 420, the material flow direction can be selected to enter the liquid outlet valve head 200 to be discharged outside the tank, or to flow into the agitator bar 400 for secondary circulation.

[0046] When the reversing valve 420 is switched to the agitator bar 400, the material enters the interior of the agitator bar 400 under the action of pumping pressure, and is ejected along the height direction through multiple convection holes 410 distributed on the agitator bar 400, forming a multi-point dispersed flow field. This dispersed flow interacts with other flowing materials in the space inside the barrel, forming vortices and convection, thereby achieving a uniform mixing and dispersion effect of the material.

[0047] If it is necessary to discharge the material inside the barrel directly, the material can be guided to the liquid outlet valve head 200 by the reversing valve 420, which can realize the external conveying of the barrel and is easy to operate.
