Description

Technical Field

[0001] The utility model relates to the technical field of stirring construction, in particular to a stirring and mixing device. Background Art

[0002] In the construction fields of buildings, flooring, etc., when constructing the solidified material layer, the raw materials need to be mixed, and then the mixed materials are sent to the area to be solidified for solidification. The mixing of these materials and slurries often requires a mixer or manual mixing, and then manual feeding. The splashing of slurries makes the construction environment very messy, which is not conducive to clean construction; especially for floor paving construction, before floor paving construction, various raw materials need to be mixed and then paved on the ground. Due to the different functional and structural requirements of the floor, the required raw materials are also quite different. For example, the raw materials of the floor in the production workshop and the floor of the outdoor stadium runway are quite different, and the difference in materials will cause the mixing tools to need to be cleaned frequently. On the one hand, it increases the difficulty of paving construction, and for manual mixing, it also significantly increases the labor intensity; on the other hand, the residual materials left by unclean cleaning affect the final construction quality, and the replacement of mixing tools will also greatly increase the construction cost.

[0003] The Chinese utility model patent (patent number: 202221117721.7) discloses a mixing device for hybrid plastic track construction, which solves the problem that the current mixing device is inconvenient to move, and the material is easily affected by the transportation time and condensed after mixing, causing inconvenience in subsequent laying. It includes a frame, and the four corners of the lower end of the frame are connected to support legs, and the inner side of the support legs is connected to a moving component, the upper end of the frame is connected to a mixing drum, and the two sides of the lower end of the mixing drum are symmetrically connected to a support seat, and the support seat is connected to the frame. In the utility model, through the setting of the moving component, the first motor drives the rotating shaft to rotate, so that the extension mechanism can extend and drive the moving wheel to support and lift the device, thereby facilitating the movement of the device. Through the above structure, the device can move to the corresponding position according to the change of the runway laying position, avoiding the inconvenience of subsequent laying caused by the long-term influence and condensation of the mixed material on the transfer vehicle.

[0004] It can be seen that in the above-mentioned prior art, although it also has a mixing drum, a first motor and other mechanisms to realize automatic mixing of raw materials, and can be conveniently moved on the floor, it is still difficult to solve the problem that the raw materials still need to be poured into the mixing drum by manpower, the work intensity is still relatively large, and it cannot adapt to the situation where the mixing drum needs to be cleaned when the raw materials are replaced. In addition, solid accumulation in the mixing drum is often produced due to solidification or chemical reaction, which adheres to the inner wall of the mixing drum, causing cleaning difficulties or affecting the quality of the next raw material mixing. Utility Model Content

DETAILED DESCRIPTION

[0024] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0025] like Figure 1-3 The stirring and mixing device shown includes a mixing paddle 1, a stirring shaft 2, a rotating power mechanism 3 and a stirring cylinder 4 for containing mixed materials. The rotating power mechanism 3 is connected to the stirring shaft 2 to drive the stirring shaft 2 to rotate; the stirring shaft 2 is pivotally connected to the stirring cylinder 4, and the stirring shaft 2 penetrates the stirring cylinder 4 along the longitudinal direction of the stirring cylinder 4; there are a plurality of mixing paddles 1, which are arranged at intervals along the axial direction of the stirring shaft 2, one end of the mixing paddle 1 is connected to the stirring shaft 2, and the other end of the mixing paddle 1 extends toward the inner wall of the stirring cylinder 4, and the other end of at least one mixing paddle 1 is detachably connected to a scraper 5, and the scraper 5 is against the inner wall of the stirring cylinder 4.

[0026] The rotary power mechanism 3 provides rotary power to drive the stirring shaft 2, the mixing paddle 1 and the scraper 5 to rotate around the axis of the stirring shaft 2. In this way, while the mixing paddle 1 stirs the raw materials (i.e., the mixed materials) in the stirring cylinder 4, the scraper 5 also scrapes the inner wall of the stirring cylinder 4 due to the friction with the stirring cylinder 4 during its rotation. In this way, the raw materials cannot adhere to the inner wall of the stirring cylinder 4 that is frictionally frictioned by the scraper 5, thereby achieving self-cleaning of the stirring cylinder 4 during the stirring process. The utility model is different from the convenient maintenance and replacement of conventional technologies by configuring a flexible disassembly method of the scraper 5. It is more suitable for replacing scrapers 5 of different thicknesses and sizes to adapt to raw materials of different viscosities and solidification speeds. In addition, for raw materials that are not easy to adhere to the inner wall or the situation where the stirring shaft 2 needs to be rotated at a high speed, the utility model is also suitable for removing the scraper 5 or shrinking the scraper 5 without abutting against the inner wall of the stirring cylinder 4 through a detachable structure. In this way, it can be suitable for various raw materials to be stirred.

[0027] The rotating power mechanism 3 may be a servo motor or a hydraulic motor, etc. The stirring shaft 2 penetrates the stirring cylinder 4 to obtain stable support, and more mixing paddles 1 can be arranged in the stirring cylinder 4 to fully mix the raw materials. The shape and size of the mixing paddle 1 are configured according to the stirring requirements, preferably a hard rod, and the number of the mixing paddles 1 can also be flexibly configured.

[0028] In order to allow more of the inner wall of the mixing cylinder 4 to be abutted by the scraper 5, thereby achieving a larger area of ​​self-cleaning capability, the inner wall surface of the mixing cylinder 4 of the present embodiment is a semicircular arc surface, the mixing shaft 2 is located on the central axis of the inner wall surface of the mixing cylinder 4, and the scraper 5 has a scraping edge 51 for scraping the inner wall surface of the mixing cylinder 4, so that the mixing cylinder 4 within the circumferential range of rotation of the scraper 5 can be scraped by the scraping edge 51 to increase the self-cleaning area.

[0029] In order to enhance the stability of the scraper 5 in scraping off adhered impurities, the two mixing paddles 1 of the present embodiment are connected to the scraper 5. Of course, the mixing paddle 1 and the scraper 5 may be appropriately fixedly connected to avoid excessive shaking of the scraper 5 when scraping the wall of the mixing tank 4. The scraper 5 has a side extending along the longitudinal direction of the mixing tank 4. The scraper 5 is against the inner wall of the mixing tank 4 through its side. By configuring the extended side of the scraper 5, the side at more positions can scrape the inner wall of the mixing tank 4. At the same time, this configuration makes the side of the scraper 5 always smoothly tangent to the inner wall of the mixing tank 4, and the force is more balanced, thereby preventing the inner wall of the mixing tank 4 from being scratched and damaged.

[0030] In order to make the scraper 5 more flexible to replace according to needs, the stirring and mixing device of this embodiment also includes a base plate 6 and a clamping plate 7. The scraper 5 is clamped between the base plate 6 and the clamping plate 7. The base plate 6 is detachably fixed to the mixing paddle 1 by fasteners. The clamping plate 7 is fixed to the base plate 6. The fasteners can be fastened by screws and nuts. The scraper 5 is clamped between the base plate 6 and the clamping plate 7, so that the installation position of the scraper 5 is flexibly adjustable and suitable for different scraping needs.

[0031] For raw materials with higher viscosity, the stirring and mixing ability of the mixing paddle 1 with an ordinary regular shape is more preferred. Preferably, the other end of the mixing paddle 1 of this embodiment is connected with a beating piece 8, and the beating piece 8 intersects with the mixing paddle 1 at different surfaces. In this way, more bending points are formed, correspondingly more stirring contact surfaces are formed, and staggered stirring layers are formed, which is more conducive to mixing raw materials.

[0032] As a preferred embodiment, since the stirring and mixing device of this embodiment requires almost no additional manual cleaning of the stirring cylinder 4, the labor intensity is reduced. In order to further reduce the labor intensity, prevent the raw materials in the stirring cylinder 4 from overflowing or splashing due to stirring and mixing, and solve the problem of material accumulation at the mouth of the stirring cylinder 4 and the need to clean the periphery of the mouth, the stirring and mixing device of this embodiment includes a bracket 9, the top of the stirring cylinder 4 is an opening 10, and the periphery of the opening 10 is connected to a baffle 11, which is used to restrain the mixed raw materials overflowing or splashing in the stirring cylinder 4, and the baffle 11 and the stirring cylinder 4 are both fixed to the bracket 9.

[0033] Since overflowed or splashed raw materials are also likely to accumulate at the joints, the bottom of the enclosure 11 of this embodiment has a first mounting edge 12 extending laterally, and the top of the mixing tank 4 has a second mounting edge 13 extending laterally. The first mounting edge 12 and the second mounting edge 13 are butted against each other, so that the enclosure 11 and the mixing tank 4 are connected at the outer wall, and the inner wall of the enclosure 11 is smoothly connected with the inner wall of the mixing rod, which effectively reduces the accumulation of mixed materials and avoids labor-intensive cleaning.

[0034] In order to further reduce the labor intensity and realize the automated operation of mixing, the bracket 9 of this embodiment is installed with a first moving mechanism 14 and a second moving mechanism 15. The first moving mechanism 14 includes at least two moving output rods, and the moving output rods are respectively connected to the suction pipes 20; the output end of the second moving mechanism 15 is drivingly connected to the first moving mechanism 14, and is used to drive the first moving mechanism 14 to rise and fall. In this way, different raw materials can be sucked in through different suction pipes 20, and driven by the first moving mechanism 14 and the second moving mechanism 15, they can be lifted and lowered and opened and closed, so that the raw materials can be gathered and injected into the mixing tank 4. Among them, the second moving mechanism 15 can adopt a chain sprocket transmission mechanism to provide sufficient lifting and lowering load-bearing capacity; the first moving mechanism 14 can adopt a hydraulic cylinder or a pneumatic cylinder, and the corresponding output rod is a hydraulic rod or a pneumatic rod; of course, the first moving mechanism 14 and the second moving mechanism 15 can also adopt a belt transmission mechanism to realize the corresponding reciprocating linear movement. Figure 1 , Figure 4 As shown, preferably, a screw pump 16 is provided in the suction pipe 20 to realize the joint movement of the pumping mechanism and the suction pipe 20. The suction inlet of the suction pipe 20 of this embodiment faces downward, and the outlet of the suction pipe 20 faces the cylinder mouth of the mixing cylinder 4, so that the raw materials sucked by the suction pipe 20 fall into the mixing cylinder 4 from above the mixing cylinder 4, so that the raw materials are more fully and evenly dispersed and mixed.

[0035] As a more preferred fixing method for raw material output, the output end of the second moving mechanism 15 of this embodiment is driven and connected to the first moving mechanism 14 through a base 21, and a cantilever beam 17 is fixed on the base 21. The free end of the cantilever beam 17 is connected to a first hook 18, and the outlet of the suction pipe 20 can be connected to the conveying pipe and the raw materials are delivered after being mounted by the first hook 18; the first hook 18 can also be mounted with a spray gun or other spraying device so that the raw materials can be accurately sprayed and spread or high-speed spraying can be achieved to enter the mixing tank 4 for mixing; the back of the bracket 9 is provided with a second hook 19 for mounting on an external frame, and the second hook 19 is convenient for mounting and connecting with the main body, so that the stirring and mixing device of the utility model can be disassembled and replaced as a whole.

[0036] The implementation methods of the present invention are not limited to these. According to the above-mentioned embodiments of the present invention, by using conventional technical knowledge and customary means in the field, without departing from the above-mentioned basic technical ideas of the present invention and without conflict, the above-mentioned preferred embodiments may also be modified, replaced or combined in various other forms, and the other embodiments obtained all fall within the scope of protection of the present invention.
