[0001] The present application relates to the technical field of solution tank stirring, and in particular to a solution tank stirrer. BACKGROUND
[0002] In a water treatment system, a solution tank is mainly used for stirring of liquid or slurry and adding of reagents to achieve fully uniform mixing and ensure treatment effect. However, in actual operation, substances in the slurry are prone to sinking and solidifying at the bottom of the solution tank, and adaptive stirring and dissolution need to be performed according to the liquid conditions at different height stages in the solution tank. In addition, in the process of stirring, solid particles such as limestone and mud components are inevitably contained in the solution or reagents, and collide with the stirring blades, so it is necessary to reduce the impact of the collision impact, avoid deformation or damage of the stirring blades, reduce vibration, and enable better dispersion and mixing of the materials, adapt to more different stirring requirements of the materials, and reduce the difficulty of replacement and maintenance.
[0003] Based on this, in order to long-term and high-efficiency stirring, the present application provides a solution tank stirrer. SUMMARY
[0004] Therefore, the technical problem to be solved by the present application is to enable the stirrer to adapt to the slurry conditions at different height stages in the solution tank and reduce the impact caused by the collision of the stirring blades with solid substances.
[0005] The above technical problem is solved by the following technical scheme: the present application provides a solution tank stirrer, which comprises a solution tank, an injection inlet is arranged above the solution tank, and a discharge outlet is arranged on the outer wall of the solution tank; a stirring structure is arranged in the solution tank; the stirring structure comprises a stirring shaft extending from the outside of the solution tank to the inside, and stirring blades are arranged at different height positions of the stirring shaft; the stirring blades can stir the liquid in the solution tank in layers by driving the stirring shaft to rotate.
[0006] In a preferred embodiment of the solution tank stirrer, the stirring blades and the stirring shaft are connected through a rotating disc, the rotating disc is fixedly connected with the stirring shaft, and the rotating disc is movably connected with the stirring blades.
[0007] In a preferred embodiment of the solution tank stirrer, a plurality of clamping grooves are formed in the rotating disc, and an installation shaft is arranged in each clamping groove.
[0008] In a preferred embodiment of the solution tank stirrer, a connecting plate is arranged on the outer wall of the stirring blade, and a clamping block is arranged on the connecting plate.
[0009] In a preferred embodiment of the solution tank stirrer: a through hole is formed in the clamping block; the stirring blade is movably connected with the mounting shaft on the rotating disc through the through hole.
[0010] In a preferred embodiment of the solution tank stirrer: the clamping block is in abutment with the clamping groove; after the abutment of the clamping block and the clamping groove, an active gap is left between the clamping groove and the groove wall of the clamping groove.
[0011] In a preferred embodiment of the solution tank stirrer: the stirring blades are arranged in layers near the bottom of the solution tank and near the middle of the solution tank.
[0012] In a preferred embodiment of the solution tank stirrer: the length of the blade diameter of the stirring blades near the middle of the solution tank is smaller than the length of the blade diameter of the stirring blades near the bottom of the solution tank.

[0021] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.
[0022] The terminology used in this invention is that which is currently widely used in the art in consideration of the function of the invention; however, these terms may vary according to the intent of those skilled in the art, precedent, or new technology in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terms used in this specification should not be construed as simple names, but rather based on their meanings and the overall description of the invention.
[0023] Reference Figure 1 This embodiment provides a solution tank stirrer, including a solution tank 1, with an inlet 11 at the top for injecting liquid or reagent; an outlet 12 on the outer wall of the solution tank 1, from which liquid can be discharged after thorough mixing, the outlet 12 being mainly located on the bottom outer wall of the solution tank 1; and a stirring structure 2 disposed inside the solution tank 1; the stirring structure 2 includes a stirring shaft 21 extending from the outside to the inside of the solution tank 1, with stirring blades 22 disposed at different heights on the stirring shaft 21, the number and size of the stirring blades 22 at each height being adjustable according to actual conditions; by driving the stirring shaft 21 to rotate, the stirring blades 22 mounted on the stirring shaft 21 rotate, thereby enabling stratified stirring of the liquid in the solution tank 1.
[0024] like Figure 2 As shown, the main structure is a double-layer blade structure. Of course, this application does not exclude the possibility of setting multiple layers of blades. At least one layer of stirring blades 22 is located at the bottom of the solution tank 1 to fully mix the slurry settled at the bottom. The diameter of the stirring blades 22 at the bottom is close to the radius of the solution tank 1 to ensure stirring without dead angles as much as possible. The diameter of the stirring blades 22 at the bottom needs to be larger than the diameter of the blades above it to optimize energy efficiency to the greatest extent and to carry out stirring work in layers.
[0025] Further, the solution tank 1 can be in a tank structure or a box structure; by arranging multiple layers of stirring blades 22, the diameter of the stirring blades 22 of each layer is gradually increased from the position of the injection port 11 at the top of the solution tank 1 to the direction of the discharge port 12 at the bottom of the solution tank 1, so that the stirring blades 22 of the upper layer can perform primary stirring to first diffuse the medicament, and the liquid in the upper part is not too serious, and the stirring blades 22 with slightly smaller diameter are arranged to further improve the overall energy efficiency, and the stirring blades 22 arranged below have larger diameter to provide stronger mixing capacity, increase fluidity, reduce solidification, and thus improve the overall dissolution efficiency.
[0026] As an optional embodiment, each layer of the stirring blades 22 is connected with the stirring shaft 21 through a rotating disc 211; the rotating disc 211 is sleeved on the stirring shaft 21 and fixedly connected with the stirring shaft 21; the rotating disc 211 is movably connected with the stirring blades 22, so that the stirring blades 22 can move relative to the rotating disc 211.
[0027] Of course, this arrangement can be made on each layer of the stirring blades 22 according to requirements; or the stirring blades 22 at the bottom layer are arranged in this way, and the stirring blades 22 at the upper layer are fixedly connected with the rotating disc 211; and the adjustment is made as required.
[0028] As an optional embodiment, a plurality of clamping grooves 2111 are circumferentially arranged on the rotating disc 211; the number of the clamping grooves 2111 can be adjusted according to the number of the stirring blades 22, and the clamping grooves 2111 are not penetrated through the rotating disc 211, as shown in the figure, and the mounting shaft 2112 is fixedly installed inside the clamping groove 2111. Figure 4
[0029] The mounting shaft 2112 has a certain length to avoid the stirring blades 22 from being thrown out in extreme cases; and if the stirring blades 22 need to be replaced due to wear, the single disassembly will also be convenient without the need to disassemble the whole.
[0030] As an optional embodiment, the outer wall of the stirring blade 22 is provided with a connecting plate 221, the connecting plate 221 is arranged in an arc shape, and the connecting plate 221 has a space between the stirring blades 22 of each layer to prevent the stirring blades 22 from colliding with each other when swinging; and the inner wall of the connecting plate 221 is provided with a clamping block 2211.
[0031] As an optional embodiment, a through hole 2212 is formed in the clamping block 2211; and the stirring blade 22 is movably connected with the mounting shaft 2112 on the rotating disc 211 through the through hole 2212.
[0032] As an optional embodiment, the clamping block 2211 is in butt joint with the clamping groove 2111, and the clamping block 2211 can be put into the clamping groove 2111 from above; after the clamping block 2211 is in butt joint with the clamping groove 2111, an active gap 2113 is left between the clamping groove 2111 and the groove side wall of the clamping groove 2111, that is, the clamping block 2211 and the clamping groove 2111 are not strictly sealed, and the active gap 2113 is reserved; when the stirring blade 22 collides with impurities in the slurry, the stirring blade 22 can swing, disperse and buffer the impact force; especially in the case of high-speed stirring, better effect can be achieved; and the swing of the stirring blade 22 can reduce the vibration caused by the collision; when the stirring blade 22 collides with solid impurities, the swing can convert part of the energy into rotational motion instead of directly transmitting to the stirring shaft 21, so as to reduce the noise of the stirrer and improve the running stability thereof.
[0033] It should be noted that the size of the active gap 2113 is not specifically limited, and the size of the active gap 2113 can be adaptively adjusted according to the hardness or other characteristics of different materials.
[0034] By setting the active gap 2113 of the stirring blade 22, the stirring structure 2 can better adapt to the high-speed rotating stirrer, reduce the influence of centrifugal force, and to some extent, reduce the vibration.
[0035] As an optional embodiment, the stirring blades 22 are arranged in layers at positions close to the bottom of the solution tank 1 and positions close to the middle of the solution tank 1. Figure 2 As shown in the figure, the stirring blades 22 at the middle positions can be initially stirred, and can also disperse the medicament after the medicament is added; and the stirring blades 22 at the bottom positions have relatively long blade diameters, because in actual application, more deposition is present at the bottom of the solution tank 1, and needs to be fully stirred.
[0036] As an optional embodiment, the blade diameter length of the stirring blades 22 close to the middle positions of the solution tank 1 is smaller than the blade diameter length of the stirring blades 22 close to the bottom positions of the solution tank 1.
[0037] As an optional embodiment, the motor 23 is arranged at one end of the stirring shaft 21 extending to the outside of the solution tank 1; the output end of the motor 23 is connected with the stirring shaft 21, and is mainly used for rotating the stirring shaft 21.
[0038] In the present application, a scheme in which the stirring shaft 21 is rotated by relying on other arrangements is not excluded.
[0039] As an optional embodiment, the outer wall of the discharge port 12 is connected with a discharge pipeline 121, and a control valve 1211 is arranged on the discharge pipeline 121; the control valve 1211 is mainly used for controlling the outflow of the liquid.
[0040] By setting the stirring structure 2, a double-layer blade structure is set, so that the stirring blade 22 at the bottom has a larger blade diameter than the stirring blade 22 at the upper layer, which ensures that the impurities deposited at the bottom can be fully mixed and dissolved, and by leaving the movable gap 2113, the impact of solid materials on the blade can be reduced.
[0041] Finally, it should be noted that the methods and devices described in detail above are only embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present application.
