A lime pulping and mixing device

Abstract

The utility model relates to the technical field of slurry stirring, more particularly to a lime pulping stirring device, which comprises a container, a stirring mechanism connected to the container, a stirring execution end of the stirring mechanism extending into the container, and a blocking structure arranged in the internal chamber of the container, wherein the fluid in the container can come into contact with the blocking structure when the stirring execution end is stirring. When the stirring member rotates to drive the slurry to flow, the fluid comes into contact with and impacts the blocking structure, thereby generating turbulence and "wave" effect and improving the problem of circulation dead angle.

Description

Technical Field

[0001] This utility model relates to the field of slurry mixing technology, and more specifically to a lime slurry mixing device. Background Technology

[0002] Lime slurry mixing devices mostly rely on the rotation of a single mixing blade to drive fluid movement. Due to the certain density and agglomeration characteristics of the slurry, relying solely on the direct push of the mixing blade can easily create "circulation dead zones" inside the container. The slurry near the inner wall of the container or the center of the mixing shaft is difficult to be fully stirred, resulting in the need to improve the compatibility of the raw materials.

[0003] To improve mixing uniformity, some devices increase the diameter of the mixing blades or the motor speed. However, larger diameter blades need to overcome greater fluid resistance during rotation, increasing the motor load. Some mixing devices, in pursuit of better mixing results, also incorporate complex internal components or excessively narrow gaps between the mixing parts and the container's inner wall. This design creates numerous cleaning dead zones inside the equipment, allowing lime slurry to easily adhere to the component surfaces and gradually solidify into lumps during mixing. Cleaning requires disassembling multiple components, making the process cumbersome and time-consuming. Furthermore, the narrow gaps between components can cause equipment malfunctions due to foreign objects getting stuck, further increasing maintenance difficulty. Utility Model Content

[0004] This utility model provides a lime slurry mixing device, the purpose of which is to improve the problem of dead zones in circulation.

[0005] The above objectives are achieved through the following technical solutions:

[0006] A lime slurry mixing device includes a container with a mixing mechanism connected to it. The mixing end of the mixing mechanism extends into the container to mix the contents of the container. A blocking structure is provided in the internal cavity of the container so that the fluid being mixed in the container can come into contact with the blocking structure when the mixing end is mixing.

[0007] The container's longitudinal inner wall is cylindrical.

[0008] The stirring mechanism includes a support fixed to the upper end of the container, a motor fixed to the upper end of the support, and a stirring component fixed to the output shaft of the motor and extending into the container. The stirring component is the stirring execution end.

[0009] The top of the agitator has a socket into which an additional blade fixed to the agitator is inserted.

[0010] The blocking structure includes a longitudinally extending flow-blocking element, which is fixed to the support element.

[0011] The flow-blocking component has longitudinally distributed openings.

[0012] The mouth is round.

[0013] The flow-blocking component has notches on both sides facing the container and away from the container to form a flow passage structure, and a wave-blocking component is fixed to the top of the flow-blocking component.

[0014] There is a gap between the stirring actuator and the blocking structure.

[0015] The barrier structure has a gap with the longitudinal inner wall of the container.

[0016] The beneficial effects of this utility model lime slurry mixing device are as follows:

[0017] The device uses longitudinally extending flow-blocking elements inside the container. When the agitator rotates and drives the slurry to flow, the fluid comes into contact with and impacts the flow-blocking elements, generating turbulence and a "wave" effect. This turbulence can improve the "circulation dead zone".

[0018] Since the turbulence generated by the flow-blocking element can replace part of the direct pushing action of the stirring blades, there is no need to increase the diameter of the stirring blades to improve the stirring effect. Smaller diameter stirring blades overcome less fluid resistance when rotating, which can significantly reduce the load on the motor.

[0019] The device is designed with a clear spacing between the mixing end and the blocking structure, and between the blocking structure and the longitudinal inner wall of the container, forming a smooth flow channel. During the mixing process, the flowing slurry can naturally wash the inner wall of the container and the surface of the flow-blocking components, reducing the adhesion and solidification of lime slurry on the surface of the components, thus reducing cleaning dead zones from the source.

[0020] The flow-blocking component features a simple design with perforated square sheet material and notches on both sides, which prevents excessive splashing of the slurry. Attached Figure Description

[0026] A lime slurry mixing device includes a cylindrical container 1. A circular flange is fixed to the top of the container 1, and a crossbeam is fixed to the flange to form a support 2. A power source, such as a geared motor 3, is mounted on the crossbeam, with the output shaft of the motor 3 facing vertically downwards. A mixing element 4 is fixed to the output shaft of the motor 3, extending into the container 1, thereby allowing the motor 3 to drive the mixing element 4 to rotate. An improvement is the inclusion of a flow-blocking element 51, positioned between the mixing element 4 and the inner wall of the container 1. When the mixing element 4 rotates to agitate the lime slurry in the container 1, the fluid contacts and impacts the flow-blocking element 51, creating turbulence and a wave-like effect. This eliminates the need for a large-diameter mixing element 4, reducing the load on the motor 3. It also allows for the creation of a space between the mixing element 4 and the flow-blocking element 51, facilitating the maintenance of both the container 1 and the mixing element 4.

[0027] Furthermore, the flow obstruction element 51 has a gap with the inner wall of the container 1 to form a flow channel, which facilitates fluid flushing, reduces the dead corners of dirt caused by the setting of the flow obstruction element 51, and reduces the difficulty of maintenance.

[0028] A longitudinal opening 52 is provided on the flow-blocking component 51 to facilitate smooth flow and avoid generating high liquid waves, thus preventing slurry from splashing everywhere. Similarly, longitudinally distributed notches are formed on the inner wall of the phase container 1 and on both sides of the agitator 4 of the flow-blocking component 51. The notches can be toothed or arc-shaped. To reduce production costs, the openings 52 can be formed by punching holes in square sheet metal, with the corners of the square sheet longitudinally distributed, and adjacent metal square sheets can be welded together. However, this will create sharp protrusions. If possible, it is recommended to avoid creating sharp protrusions on the inner wall of the phase container 1 and on both sides of the agitator 4 of the flow-blocking component 51.

[0029] Alternatively, the top of the agitator 4 can be formed into a radially extending beam-like structure with cuts, and additional blades 5 in the cuts can be inserted to increase the central stirring capacity, allowing the fluid to flow smoothly in the container 1. The overall shape of the agitator 4 is a trapezoidal frame structure to form a frame or anchor structure, facilitating the welding of additional stirring blades. Considering processing costs and versatility, welding and bolt-nut assembly methods are preferred for fixing the various accessories. A wave-blocking member 54 extending horizontally is fixed to the top of the flow-blocking member 51, which not only facilitates fixing to the support member 2 but also prevents waves generated by the flow-blocking member 51 from splashing out of the container 1.
