Description

Technical Field

[0001] The utility model belongs to the technical field of stirrers, and in particular relates to a mobile stirrer. Background Art

[0002] In terms of adding chemicals for sewage treatment, agitators are indispensable equipment. Existing solution tanks are generally equipped with an agitator. When adding chemicals, multiple dosing tanks are often used to add chemicals at the same time, which requires multiple agitators, resulting in increased equipment investment. Although movable stirring devices are available on the market, in order to provide stirring stability, their movable brackets are often made bulky, which on the one hand causes high manufacturing costs for the mobile stirring device, and on the other hand poor mobility. For this reason, we designed and proposed a mobile agitator according to the needs. Utility Model Content

[0003] The purpose of the utility model is to solve the disadvantage of the existing technology that the fixed setting of the agitator cannot perform multi-point stirring, and a mobile agitator is proposed. The mobile agitator can be moved for stirring, and can perform stirring operations on multiple dosing tanks, realizing the function of multi-point stirring, which can reduce the investment cost of sewage treatment equipment and also improve the stirring efficiency of the solution.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A mobile stirrer is designed, comprising a traveling frame, the traveling frame is in an "I"-shaped structure, a universal traveling wheel is fixed at the bottom of the traveling frame, a handle is fixed at one end of the traveling frame, a suspension support arm of a single-rod structure is fixed at the center of the traveling frame, the top end of the suspension support arm is bent, and a suspension stirring mechanism is suspended thereon, and a winch lifting mechanism for lifting the suspension stirring mechanism is fixed on the traveling frame;

[0006] The suspension stirring mechanism comprises a suspension, a stirring motor is fixedly arranged on the suspension, a stirring shaft is fixedly arranged on the output rotating shaft of the stirring motor, the stirring shaft is composed of two flat plates in a blade structure, a receiving cavity is formed between the flat plates, a plurality of stirring blades are connected to the two sides of the receiving cavity in a rotational direction along the length direction of the stirring shaft, and the stirring blades hang down in the receiving cavity when the stirring shaft is in a non-rotating state;

[0007] Both sides of the suspension are provided with outwardly extending support mechanisms;

[0008] It also includes an electric control box, which is fixedly arranged on the suspension support arm and is connected to the hoisting lifting mechanism and the suspension stirring mechanism through wires.

[0009] Furthermore, the winch lifting mechanism includes a winch motor, which is fixedly mounted on a traveling frame; a winding disk of the winch motor is provided with a rope for lifting and lowering the suspension stirring mechanism; a support ear for connecting the rope is fixedly mounted on the suspension stirring mechanism; and pulleys for guiding the rope are provided at the end and back of the suspension support arm.

[0010] Furthermore, the stirring blade is connected to the accommodating cavity via a rotating shaft, and the rotating shaft of the stirring blade deviates from the axial position of the stirring shaft.

[0011] Furthermore, the support mechanism includes an extension rod, which is fixed on both sides of the suspension, and a matching sleeve is sleeved on the extension rod. A support plate with a cross-section forming an inverted L-shaped structure is fixedly provided at the bottom of the sleeve, a handle is fixedly provided on the support plate, and a locking bolt is threadedly connected to the sleeve.

[0012] Furthermore, an anti-slip pad is fixedly provided on the outer side of the support plate.

[0013] Furthermore, the bottom of the support plate is in an arc structure.

[0014] The mobile agitator proposed by the utility model has the following beneficial effects:

[0015] (1) The utility model can perform mobile stirring operations on multiple dosing tanks, realize the function of multi-point stirring, reduce the investment cost of sewage treatment equipment, and also improve the stirring efficiency of the solution.

[0016] (2) The utility model adopts a suspension method to realize the lifting and lowering of the suspension stirring mechanism. On the one hand, the position of the suspension stirring mechanism can be manually moved during the lifting process, making it easier to insert it into the smaller tank mouth of the solution tank, which can improve the working efficiency of mobile stirring. On the other hand, the suspension method can also be used for stirring with a larger tank diameter. When the tank diameter of the solution tank is larger than the maximum span of the walking frame, the traditional mobile stirring device cannot stir the solution. The utility model can manually pull the suspension stirring mechanism into the solution tank with a large tank diameter. At the same time, the use of this suspension method can reduce the overall size of the walking frame and reduce the cost of equipment manufacturing. The smaller size also facilitates the movement of the stirrer and improves its flexibility.

[0017] (3) The utility model provides a retractable opening mechanism on both sides of the suspension, so that the suspension stirring mechanism and the solution tank can be fixed together to temporarily form an integral structure, which can improve the stability of stirring. At the same time, the opening mechanism can be adapted to solution tanks of different diameters by adopting this retractable and adjustable manner, making the application more convenient and flexible.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0030] The structural features of the utility model are now described in detail with reference to the accompanying drawings of the specification.

[0031] See also Figure 1-Figure 7 A mobile mixer comprises a traveling frame 1, the traveling frame 1 is in an "I"-shaped structure, a traveling wheel 11 with a universal function is fixed to the bottom of the traveling frame 1, the traveling wheels 11 are respectively at the four corners of the traveling frame 1, a handle 12 is fixed to one end of the traveling frame 1, a suspension support arm 2 of a single-rod structure is fixed at the center of the traveling frame 1, the top of the suspension support arm 2 is bent, and a suspension stirring mechanism 4 is suspended, wherein the top of the suspension support arm 2 is located at the center of the traveling frame 1, which can improve the stability of the suspension stirring mechanism 4 in lifting and lowering, and a winch lifting mechanism for lifting and lowering the suspension stirring mechanism 4 is fixed on the traveling frame 1, and the winch lifting mechanism is used to lift and lower the suspension stirring mechanism 4. The lowering mechanism includes a hoisting motor 3, which is fixedly arranged on the traveling frame 1. A rope 31 for lifting and lowering the suspended stirring mechanism 4 is provided on the winding disk of the hoisting motor 3. A support ear 42 for connecting the rope 31 is fixedly provided on the suspended stirring mechanism 4. A pulley 21 for guiding the rope 31 is provided at the end and back of the suspension support arm 2. The lifting and lowering of the suspended stirring mechanism 4 on the traveling frame 1 can be realized by the hoisting motor 3. The suspended stirring mechanism 4 can be lifted first, and then the traveling frame 1 can be pushed onto the solution tank to be stirred, and then the suspended stirring mechanism 4 can be lowered into the solution tank, and the solution in the solution tank can be stirred.

[0032] The suspension stirring mechanism 4 includes a suspension 41, on which a stirring motor 43 is fixedly provided, and on the output rotating shaft of the stirring motor 43, a stirring shaft 44 is fixedly provided, the stirring shaft 44 is composed of two flat plates in a blade structure, and a receiving chamber 45 is formed between the flat plates, and a plurality of stirring blades 46 are connected to the two sides of the receiving chamber 45 along the length direction of the stirring shaft 44 for rotation, and when the stirring shaft 44 is in a non-rotating state, the stirring blades 46 hang down in the receiving chamber 45, wherein the stirring blades 46 are connected in the receiving chamber 45 through a rotating shaft, and the rotating shaft of the stirring blades 46 deviates from the axial position of the stirring shaft 44, so that the center of gravity of the stirring blades 46 deviates from the stirring shaft 44. The rotating axis of the stirring shaft 44, when the stirring motor 43 drives the stirring shaft 44 to rotate at a high speed, is acted upon by the centrifugal force, and the stirring blades 46 will be unfolded from the accommodating chamber 45. The unfolded stirring blades 46 stir in the solution tank to form a plug flow, so that the upper liquid and the lower liquid in the solution tank flow up and down during the stirring process, which can better stir the solution. When the stirring shaft 44 stops rotating, the stirring blades 46 will re-enter the accommodating chamber 45, and the stirring blades 46 stacked on each other can completely enter the stirring shaft 44, and the stirring blades 46 will not be exposed, making the exterior of the stirring shaft 44 neater and tidy, making it easier for the stirring shaft 44 to pass through the mouth of the solution tank.

[0033] In order to enable the suspended stirring mechanism 4 to operate stably during stirring, a support mechanism 5 extending outward is provided on both sides of the suspension 41, and the support mechanism 5 includes an extension rod 51, which is fixedly arranged on both sides of the suspension 41, and an adaptive sleeve 52 is sleeved on the extension rod 51, and the sleeve 52 can slide on the extension rod 51, and a support plate 53 with an inverted L-shaped cross section is fixedly provided at the bottom of the sleeve 52, and the inverted L-shaped support plate 53 can be well stuck on the tank mouth of the solution tank, and a handle 54 is fixedly provided on the support plate 53, and the handle 54 is used to adjust the support plate 53 to slide outward, and a locking bolt 55 is threadedly connected to the sleeve 52. In specific use, after the stirring shaft 44 enters the solution tank, the support plate 53 is pulled to both sides by the handle 54, so that the support plates 53 on both sides are tightly against the tank mouth, and then the support plates 53 are fixed by the locking bolts 55, so as to realize the fixing of the suspension stirring mechanism 4 on the tank mouth of the solution tank. In order to better fix the support plate 53 and the tank mouth to each other and avoid slipping during fixing, an anti-skid pad 56 can be fixed on the outer side of the support plate 53. In addition, the bottom of the support plate 53 is an arc structure. Such a design can make the bottom of the support plate 53 better fit on the inner wall of the tank mouth, increase the contact area, and improve the stability of fixing. The support plate 53 with slidable adjustment on both sides can be applied to tank mouths of different sizes. By arranging a retractable support mouth mechanism 5 on both sides of the suspension 41, the suspension stirring mechanism 4 can be fixed together with the solution tank to temporarily form an integral structure, which can improve the stability of stirring. At the same time, by adopting this retractable and adjustable method, the support mouth mechanism 5 can be applied to solution tanks of different calibers, and the application is more convenient and flexible.

[0034] It also includes an electric control box 6, which is fixedly arranged on the suspension support arm 2 and is respectively connected to the hoisting lifting mechanism and the suspension stirring mechanism 4 through wires. The electric control box 6 can control the hoisting lifting mechanism to lift the suspension stirring mechanism 4, and can also adjust the stirring speed of the suspension stirring mechanism 4.

[0035] The mobile agitator of the utility model has a lighter structure and is easy to operate and move. On the one hand, it can perform mobile stirring operations on multiple dosing tanks to achieve the function of multi-point stirring. On the other hand, it can reduce the investment cost of sewage treatment equipment when it is put into production and also improve the stirring efficiency of the solution.

[0036] Specifically, when in use, the suspension stirring mechanism 4 is lifted and lowered by a suspension method. On the one hand, the position of the suspension stirring mechanism 4 can be manually moved by the handle 54 during the lifting process, making it easier to insert it into the smaller tank opening of the solution tank, thereby improving the working efficiency of mobile stirring. On the other hand, the suspension method can also be used for stirring with a larger tank diameter. When the tank diameter of the solution tank is larger than the maximum span of the walking frame (such as Figure 6 As shown in the figure), the traditional mobile stirring device cannot stir the solution, while the utility model can send the suspended stirring mechanism 4 into the solution tank with a large tank diameter through manual traction. At the same time, the use of this suspension method can reduce the overall size of the walking frame 1 and reduce the cost of equipment manufacturing. The smaller size also facilitates the movement of the stirrer and can improve its mobility.

[0037] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
