Description

Technical Field

[0001] This utility model relates to the technical field of mixing equipment, and in particular to a modifier mixing equipment with a rotary spray mixing structure. Background Technology

[0002] Currently, in the field of modifier production, the mixers used typically consist of a base, a cylinder, a main shaft, and a drive motor that drives the main shaft to rotate. The top of the cylinder is equipped with a cover, and the bottom of the cylinder is equipped with stirring blades. During operation, the drive motor drives the main shaft to rotate, causing the stirring blades to rotate at high speed. This causes the material to float upwards along the inner wall of the cylinder, forming a vortex. Due to centrifugal force, a central cavity is formed inside the cylinder. The material above is guided to the central space of the cylinder and falls onto the stirring blades. Then, it moves upwards along the inner wall of the cylinder in all directions. Through this cyclical motion, the material is mixed.

[0003] In the process of material mixing, the materials to be added generally exist in two forms. For powdery raw materials, a screw conveyor is usually used to lift them and allow them to fall smoothly into the inside of the cylinder from the top opening; while liquid materials, such as liquid additives, are directly fed into the top opening of the cylinder and fall into the inside of the cylinder to participate in the mixing.

[0004] However, the above-mentioned mixer still has significant drawbacks when adding and mixing materials in two forms:

[0005] Firstly, during the feeding process, the cylinder cover needs to be opened and the drive motor needs to be stopped. During this process, the addition of powdery raw materials can easily cause dust to be generated, which can then be dispersed into the surrounding production environment, polluting the working environment and potentially affecting the health of the operators. Secondly, when liquid materials are added, they tend to mix and agglomerate rapidly with localized powdery raw materials, making it impossible to achieve uniform dispersion. This seriously affects the uniformity and efficiency of material mixing during the production of the modifier.

[0006] In view of this, the inventors specifically designed a modifier mixing device with a rotary spray mixing structure, which led to this invention. Utility Model Content

[0007] To solve the above problems, the technical solution of this utility model is as follows:

[0008] A modifier mixing device with a rotary spray mixing structure includes a base, a cylinder, a main shaft, a drive motor for driving the main shaft to rotate, and a screw conveyor. The top of the cylinder is provided with a top cover and the bottom of the cylinder is provided with stirring blades that are driven by the main shaft. It also includes a liquid material adding device located above the cylinder. One side of the top cover is rotatably connected to the top opening of the cylinder and the upper end of the top cover is provided with a guide tube that communicates with the inner cavity of the cylinder. The liquid material adding device includes a storage container, a connecting hose, and a disperser. The disperser is connected to the bottom of the storage container through the connecting hose and is vertically installed at the top of the inner cavity through the guide tube. The top cover has a feeding port, and the discharge port of the screw conveyor is provided with a flexible conduit that can pass through the feeding port.

[0009] Preferably, the screw conveyor includes a hopper, a screw pipe, and a feeding motor. The feeding motor is located at the top of the screw pipe, and the screw pipe is provided with screw feeding blades that are connected to the feeding motor for transmission. The bottom of the hopper is connected to the bottom of the screw pipe.

[0010] Preferably, the flexible conduit is a cylindrical structure made of canvas or plastic film, with openings on the upper and lower sides.

[0011] Preferably, the upper opening of the flexible catheter is larger than its lower opening.

[0012] Preferably, the disperser is a spiral nozzle and is fitted onto the lower end of the connecting hose.

[0013] Preferably, the connecting hose is a rubber hose.

[0014] Preferably, the inner side of the guide cylinder is provided with a guiding structure, and the guiding structure has a guiding hole through the middle for the connecting hose to slide through.

[0015] Preferably, the guiding structure is annular and is snapped and fixed in the extension direction of the inner side of the guide cylinder, and the inner ring wall of the guiding structure is embedded with a plurality of spherical guiding structures for rolling contact with the connecting hose.

[0016] Preferably, at least two of the guiding structures are provided along the guide cylinder.

[0017] Preferably, the upper cover is provided with a through mounting hole, the mounting hole including a connecting section that fits into the guide cylinder and a guide section located at the lower end of the connecting section with a gradually increasing opening, the guide section having an inclined guide surface.

[0018] The beneficial effects of this utility model are as follows:

[0019] This invention features a feeding port on the top cover, allowing the conveying of powdery raw materials via a flexible conduit without opening the cover, thus effectively preventing dust dispersion. Simultaneously, a guide tube guides the connecting hose and disperser of the liquid material addition device, ensuring the disperser is positioned vertically at the top of the inner cavity. This allows for thorough dispersion of the liquid material, and when combined with the start-up of the drive motor, further enhances the uniformity and efficiency of the liquid material mixing.

[0020] In addition, the top cover and the cylinder are rotatably connected. When the cover is opened by lateral rotation, the flexible guide tube will automatically be misaligned with the feed port. At the same time, due to the fixed length of the connecting hose, the disperser will retract into the guide cylinder for temporary storage under its pulling force, thereby avoiding the above structure from affecting the opening process of the top cover and facilitating the feeding or maintenance of the main material.

[0021] In particular, the guiding structure inside the guide tube allows the connecting hose to slide smoothly and remain centered within the guide tube, facilitating the opening and closing process of the top cover.

[0022] In addition, the segmented design of the mounting hole can use the guide surface to guide the disperser, allowing it to smoothly enter the guide cylinder and preventing the disperser from getting stuck in the opening of the mounting hole during the opening of the top cover.

[0032] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0033] Please see Figures 1 to 5 This is a modified agent mixing device with a rotary spray mixing structure, which is the preferred embodiment of the present utility model. It includes a base 100, a cylinder 200, a main shaft 300, a drive motor 400 for driving the main shaft 300 to rotate, and a screw conveyor 500. The top of the cylinder 200 is provided with a top cover 210 and the bottom of the cylinder is provided with stirring blades (not shown in the figure) that are driven by the main shaft 300.

[0034] Specifically, the drive motor 400, main shaft 300, and cylinder 200 are all mounted and fixed on the base 100. The drive motor 400 and main shaft 300 are connected by a transmission structure (not shown in the figure) inside the base 100, such as a transmission belt. The main shaft 300 then transmits power along the bottom of the cylinder 200 to the stirring blades at the bottom of the cylinder, thus realizing the overall driving process. Generally, a feeding device 250 controlled by a cylinder 251 is also designed on one side of the cylinder 200 to facilitate the output of the stirred product.

[0035] like Figure 1 , 2As shown, it also includes a liquid material adding device 600 located above the cylinder 200. One side of the upper cover 210 is rotatably connected to the top opening of the cylinder 200, and its upper end is vertically provided with a guide cylinder 220 that communicates with the inner cavity 260 of the cylinder 200. The liquid material adding device 600 includes a storage container 610, a connecting hose 620, and a disperser 630. The disperser 630 is connected to the bottom of the storage container 610 through the connecting hose 620 and is vertically installed at the top of the inner cavity 260 through the guide cylinder 220. The upper cover 210 has a feeding port 240, and the discharge port 540 of the screw conveyor 500 is provided with a flexible conduit 550 that can pass through the feeding port 240.

[0036] Specifically, such as Figure 2 As shown, one side of the top cover 210 is rotatably connected to the upper end of the cylinder 200 via a cover-opening motor 230 fixed to the top of the side wall of the cylinder 200, and the opening state of the top cover 210 is controlled by the cover-opening motor 230.

[0037] In this embodiment, the storage container is mounted and fixed to the upper part of the wall or base by a bracket to achieve the setting on the upper side of the cylinder.

[0038] Preferred, such as Figure 1 As shown, the screw conveyor 500 includes a hopper 510, a screw pipe 520, and a feeding motor 530. The feeding motor 530 is located at the top of the screw pipe 520. The screw pipe 520 is provided with screw feeding blades that are connected to the feeding motor 530 for transmission. The bottom of the hopper 510 is connected to the bottom of the screw pipe 520. The upper end of the screw pipe 520 and the side away from the feeding motor 530 are provided with a discharge port 540.

[0039] Thus, the powdery raw material in the hopper 510 is spirally lifted by the spiral feed pipe 520 and the feeding motor 530, so that it falls stably from the discharge port 540 directly down the flexible guide tube 550 into the feed port 240 of the upper cover 210 and enters the inner cavity 260 of the cylinder 200.

[0040] Preferred, such as Figure 2 As shown, the flexible conduit 550 is a cylindrical structure made of canvas or plastic film, with openings on both the upper and lower sides. The upper opening of the flexible conduit 550 is larger than its lower opening.

[0041] In this embodiment, the flexible conduit 550 is a cylindrical structure made of canvas. In addition, in order to avoid the adhesion of powdery raw materials, an anti-adhesion film can be laminated on the inner wall of the flexible conduit 550, so that the powdery raw materials can be fed smoothly.

[0042] Preferred, such as Figure 3 , 4 As shown in Figure 5, the disperser 630 is a spiral nozzle and is sleeved on the lower end of the connecting hose 620, which is a rubber tube.

[0043] Combination Figure 5 The spiral nozzle includes a threaded connection end 631, a base 632, and a spiral nozzle 633. The spiral nozzle 633 is spiral-shaped, wider at the top and narrower at the bottom. It is connected to the bottom of the connecting hose 620 via the threaded connection end 631, making the spiral nozzle 633 integrated with the entire connecting hose 620 and the storage container 610. In this embodiment, the storage container 610 is also funnel-shaped, wider at the top and narrower at the bottom. Thus, when liquid material is added to the storage container 610, it can be conveyed along the connecting hose 620 to the position of the spiral nozzle, where it is guided to... Figure 5 Within the range shown, the liquid material is evenly sprayed into the interior of the cylinder 200.

[0044] Preferred, such as Figure 2 , 3 As shown, a guiding structure 700 is provided on the inner side of the guide cylinder 220. A guiding hole 710 is formed through the middle of the guiding structure 700 for the connecting hose 620 to slide through. The guiding structure 700 is annular and is locked and fixed in the extension direction of the inner side of the guide cylinder 220. Several spherical guiding structures 720 are embedded in the inner ring wall of the guiding structure 700 for rolling contact with the connecting hose 620.

[0045] Preferably, there are two guide structures 700 along the guide cylinder 220 and distributed on the upper and lower sides of the guide cylinder 220. The guide structure 700 located on the lower side should satisfy the requirement that when the upper cover 210 is opened, the disperser 630 can be smoothly retracted into the guide cylinder 220.

[0046] Preferably, the top cover 210 is provided with a mounting hole 270, which includes a connecting section 271 that fits into the guide cylinder and a guide section 272 located at the lower end of the connecting section 271 with a gradually increasing opening. The guide section 272 has an inclined guide surface 273.

[0047] The beneficial effects of this utility model are as follows:

[0048] This invention utilizes a feeding port 240 on the top cover 210 to transport powdered raw materials conveyed by the screw conveyor 500 without opening the cover, thus effectively preventing dust dispersion. Simultaneously, a guide tube 220 guides the connecting hose 620 and the disperser 630 of the liquid material adding device 600, allowing the disperser 630 to be smoothly and vertically positioned at the top of the inner cavity 260. This enables the disperser 630 to fully disperse the liquid material, and when the drive motor 400 is turned on, the uniformity and efficiency of the liquid material mixing are further improved.

[0049] In addition, the top cover 210 is rotatably connected to the cylinder 200. When the cover is opened by lateral rotation, the flexible conduit 550 will automatically be misaligned with the feed port 240. At the same time, due to the fixed length of the connecting hose 620, the disperser 630 will retract into the guide cylinder 220 for temporary storage under its pulling force, thereby avoiding the above structure from affecting the opening process of the top cover 210 and facilitating the feeding or maintenance of the main material.

[0050] In particular, the guiding structure 700 inside the guide tube 220 allows the connecting hose 620 to slide smoothly within the guide tube and remain centered, facilitating the opening and closing process of the cover 210.

[0051] In addition, the segmented design of the mounting hole 270 can guide the disperser 630 using the guide surface 273, allowing it to smoothly enter the guide cylinder 220, and preventing the disperser 630 from getting stuck in the opening of the mounting hole 270 during the opening of the cover 210.

[0052] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
