Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a mixer anti-floating material device. Background Art

[0002] When producing mixtures such as putty powder, in addition to manual stirring with an electric drill, it is common to use equipment with a stirring roller driven by a motor. The reactor is more widely used in the production of chemical materials because it has the feature of adjusting the shell temperature of the material during stirring.

[0003] When using a reactor for stirring production, sometimes there are some materials that will react violently in direct contact. At this time, the operator will stir the reaction of one of the reactants according to the properties of the reactants. After the reactant is completely converted, another reactant that does not react violently with the product of the previous reactant will be added to reduce the risk of stirring.

[0004] However, the raw materials stirred by the existing reactors include solids and liquids placed in the reaction chamber at the same time. Although the solid-liquid mixing can be achieved through repeated stirring by the stirring roller, there are also a small number of reactants that float on the surface of the mixture because they have not yet reacted completely. After the specific reactants are added, they come into direct contact with them and react violently, causing production safety accidents when the operator feeds the materials through the feeding port due to close contact with the reacting reactants.

[0005] In view of the above problems, a technical solution for a mixer is proposed which can effectively reduce accidents caused by floating materials. Utility Model Content

[0006] The utility model aims to solve the problems in the prior art and proposes a mixer anti-floating material device.

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. Obviously, the embodiments described are only some embodiments of the present invention, rather than all embodiments.

[0022] Mixer anti-floating device, such as Figure 1 As shown, it includes a shell 1, a stirring shaft and several groups of fan blades for stirring materials. A reaction chamber 12 for accommodating materials is opened in the shell 1. The stirring shaft and several groups of fan blades are arranged in the reaction chamber 12. A feeding cover 2 is detachably connected to the shell 1. The specific connection method is a threaded connection. Each group of fan blades is fixedly and evenly arranged around the circumference of the stirring shaft. An electric drive mechanism for driving the stirring shaft to rotate is fixedly arranged outside the shell 1. A pressing component is arranged on the shell 1 for pressing the material floating on the surface of the material under the feeding cover 2 to sink it into the inside of the material.

[0023] Practical effect: The reactants floating on the surface of the material below the feeding cover 2 are pressed into the material by the material pressing member, thereby greatly reducing the situation where the floating material that is not completely stirred directly reacts chemically with the reactants added later, and effectively improving the safety of the reactor.

[0024] like Figures 2 to 6The cam 12 is provided with a plurality of camming holes 31 for holding the cam 12 in a closed position, and the cam 12 is provided with a plurality of camming holes 32 for holding the cam 12 in a closed position.

[0025] The pressing piece 3 is formed with a slide groove 32 for accommodating the telescopic rod 4 to slide along it, and the groove wall of the slide groove 32 is provided with a plurality of guide grooves 321. The telescopic rod 4 is formed with a guide block 41 embedded in the guide groove 321, and the guide block 41 slides along the guide groove 321. The upper end of the guide groove 321 is extended to form a first transverse groove structure for the guide block 41 to abut against the pressing block and move toward the groove opening of the slide groove 32, and the lower end of the guide groove 321 is extended to form a second transverse groove structure for restricting the sliding of the pressing block. In this specific embodiment, the guide grooves 321 are two and symmetrically arranged along the axis of the slide groove 32.

[0026] In the initial state, the telescopic rod 4 is embedded in the slide groove 32, and the guide block 41 is located in the second transverse groove structure, and the telescopic rod 4 abuts against the outer wall of the housing 1;

[0027] When the material in the reaction chamber 12 is small, the telescopic rod 4 is rotated to make the guide block 41 disengage from the second transverse groove structure. At this time, the material pressing piece 3 falls naturally under the influence of gravity. Then, the telescopic rod 4 is rotated in the same direction again to make the guide block 41 enter the first transverse groove structure. At this time, the telescopic rod 4 can be pulled up and down, so that the plate-like structure of the material pressing piece 3 is continuously immersed in the material.

[0028] When resetting, the pressing piece 3 is pulled up and the telescopic rod 4 is lifted up, and then the telescopic rod 4 is rotated in the opposite direction. The telescopic rod 4 falls down due to its own weight, and the telescopic rod 4 is rotated in the opposite direction again until the telescopic rod 4 is reset to the second transverse groove structure.

[0029] like Figure 1 As shown, in order to prevent the pressing piece 3 from being blocked by the fan blades when pressing down, a gap is formed between adjacent fan blades to accommodate the pressing piece 3 passing through, and when the stirring shaft stops rotating, the gap between adjacent fan blades is aligned with the feeding cover 2;

[0030] In order to prevent the material added into the reactor from being mainly poured onto the pressing member, the shell 1 is provided with a clearance groove 11 for guiding the pressing member to slide away from the bottom of the feeding cover 2, and the pressing member is movably connected with a shield plate 5 which slidably covers the clearance groove 11. In this specific embodiment, the pressing member 3 slides against the lower end surface of the shield plate 5, and the telescopic rod 4 is movably connected to the shield plate 5. The maximum angle of rotation of the pressing member by the clearance groove 11 is 120 degrees.

[0031] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-limiting from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
