Description

Technical Field

[0001] This utility model relates to the technical field of building material slurry mixing equipment, and in particular to a continuous mixing equipment for building material slurry. Background Technology

[0002] In modern construction engineering, various building material slurries, such as cement-based mortar, gypsum slurry, and waterproof coatings, need to be thoroughly mixed according to precise proportions to meet the requirements for workability and final strength. Currently, the preparation process of building material slurries still generally uses intermittent mixing equipment, and its operation process typically includes steps such as feeding, mixing, discharging, and washing.

[0003] As shown in the reference case "Green Building Materials Production Concrete Mixing Equipment" announcement number "CN216803943U", during the use of the mixing equipment, it is impossible to clean the inside of the mixing equipment, which easily causes concrete to adhere to the inner wall of the mixing equipment. After the concrete solidifies, it can easily affect the normal operation of the mixing equipment. This green building materials production concrete mixing equipment has the advantage of being easy to clean, thus improving the stability of the mixing equipment.

[0004] Most existing mixing equipment still consists of a single mixing chamber. After each mixing cycle, the machine must be stopped for material discharge and cleaning, which cannot achieve continuous and uninterrupted slurry output and seriously affects the overall mixing efficiency. Especially in large-scale construction or automated continuous feeding scenarios, this type of structure is difficult to meet the needs of efficient and stable production. Utility Model Content

[0005] Therefore, it is necessary to address the issue that most existing mixing equipment still relies on a single mixing chamber, requiring shutdown for material discharge and cleaning after each mixing cycle. This prevents continuous and uninterrupted slurry output, severely impacting overall mixing efficiency. This is particularly problematic in large-scale construction or automated continuous feeding scenarios, where such structures struggle to meet the demands for efficient and stable production. To address this issue, a continuous mixing equipment for building material slurry is provided, comprising: a storage silo with two mixing chambers on one side, connected by a single switching valve; and a switching mixing mechanism for switching the mixing between the two mixing chambers, located on one side of each mixing chamber. The switching mixing mechanism includes a drive box fixedly installed on one side of the storage silo, with a switching component inside the drive box, and mixing components on one side of each of the two mixing chambers.

[0006] The switching assembly includes a motor fixedly mounted on the top of the drive box, an electric push rod fixedly mounted on the bottom of the drive box, a sleeve rotatably mounted on the output end of the electric push rod, the sleeve being slidably connected to the output end of the motor, a first gear fixedly mounted on the outside of the sleeve, and a second gear provided on both sides of the first gear, with the two second gears being staggered.

[0007] The first gear meshes with the adjacent second gear, and the edges of multiple teeth of the two second gears are all set in an arc shape.

[0008] Both second gears are rotatably mounted inside the drive box. Both mixing chambers are equipped with transmission rods at their tops. One end of each transmission rod extends into the drive box, and the two transmission rods are located on opposite sides of the two second gears. The second gears are connected to the adjacent transmission rods via pulleys.

[0009] The switching valve is configured in a T-shape and is located between the two mixing chambers and the storage chamber.

[0010] The stirring assembly includes a drive rod fixedly installed at the other end of the transmission rod, and stirring blades are fixedly installed on the outer side of the drive rod.

[0011] The stirring blades are configured in a spiral shape, and two drive frames are fixedly mounted on the surface of the drive rod.

[0012] Scrapers are fixedly installed at the bottom of the two drive frames, and shearing plates are fixedly installed on the other side of the scrapers.

[0013] Beneficial effects 1. By switching components, a single drive source can be switched between the two mixing chambers, achieving alternating drive and reducing equipment structural complexity and cost. The two mixing chambers alternately mix and discharge, effectively improving the equipment's continuous operation capability and avoiding the efficiency impact of frequent shutdowns in traditional intermittent mixing. The mixing components improve mixing uniformity, avoid dead zones and sedimentation, and ensure stable slurry mixing quality.

[0014] 2. The mixing blades are designed in a spiral shape, which can apply continuous axial propulsion and radial tumbling force to the building material slurry during the rotation of the drive rod, causing the material inside the mixing chamber to flow simultaneously in the up-down and inside-out directions, thereby accelerating the mixing speed and improving the mixing uniformity. The spiral blade structure is particularly suitable for building material slurries with high viscosity or containing particulate fillers. Attached Figure Description

[0023] The following is combined Figures 1-4 This invention describes a continuous mixing and blending equipment for building material slurry.

[0024] In one embodiment, a continuous mixing device for building material slurry includes: a storage silo 100, two mixing chambers 200 are provided on one side of the storage silo 100, and a common switching valve 210 is fixedly installed between the storage silo 100 and the two mixing chambers 200; a switching mixing mechanism 300 is provided on one side of the two mixing chambers 200 for switching the mixing of the two mixing chambers 200; wherein, the switching mixing mechanism 300 includes a drive box 310 fixedly installed on one side of the storage silo 100, a switching component 320 is provided inside the drive box 310, and a mixing component 330 is provided on one side of each of the two mixing chambers 200.

[0025] In this embodiment, the switching component 320 allows the drive source to switch between the two mixing chambers 200, thus enabling the switching drive of the two mixing chambers 200 to be performed using a single drive source, reducing the overall structural complexity and manufacturing cost. By controlling the switching of the mixing mechanism 300, the two mixing chambers 200 can operate alternately, with one side mixing while the other discharges or feeds material, improving the continuity and efficiency of the overall equipment. The two mixing chambers 200 alternately perform mixing and unloading operations, avoiding the drawbacks of frequent shutdowns due to discharge and cleaning operations in traditional intermittent mixing equipment, ensuring the continuity and stability of the slurry mixing process. The mixing component 330 can improve the mixing effect, avoid mixing dead zones and material deposition, and improve the uniformity and stability of the slurry mixing. It should be noted that existing building material slurry mixing equipment typically includes a storage silo 100, a single mixing chamber 200, a motor 321, a mixing shaft, a paddle assembly, and a discharge valve. The switching valve 210 is installed between the storage silo 100 and the two mixing chambers 200 to control the material to be introduced into either mixing chamber 200 as needed. It has a compact structure and does not change the original material supply path. The switching mixing mechanism 300 is centrally located on one side. The switching component 320 realizes the power transmission between the two mixing chambers 200 from a single drive source without increasing the number of additional drive shafts or drive sources.

[0026] like Figure 2 and Figure 3 As shown, the switching assembly 320 includes a motor 321 fixedly installed on the top of the drive box 310, an electric push rod 322 fixedly installed on the bottom of the drive box 310, a sleeve 323 rotatably installed on the output end of the electric push rod 322, the sleeve 323 being slidably connected to the output end of the motor 321, a first gear 324 fixedly installed on the outside of the sleeve 323, and a second gear 325 provided on both sides of the first gear 324, with the two second gears 325 being staggered.

[0027] In this embodiment, the electric push rod 322 drives the sleeve 323 to slide axially along the output end of the motor 321, enabling the first gear 324 to quickly switch between two second gears 325, thereby completing the alternating drive of the two mixing chambers 200. After the first gear 324 meshes with the selected second gear 325, the output torque of the motor 321 can be transmitted to the mixing component 330 inside the corresponding mixing chamber 200, realizing the switching execution of the mixing function.

[0028] The first gear 324 meshes with the adjacent second gear 325, and the edges of multiple teeth of the two second gears 325 are all set in an arc shape.

[0029] In this embodiment, the first gear 324 meshes with the adjacent second gear 325. Multiple tooth edges of the two second gears 325 are all designed with an arc shape. This arc tooth design allows the first gear 324 to stably transition to the meshing position of any of the second gears 325 during its up-and-down sliding motion. The arc edges provide excellent guidance, reducing meshing jamming or skipping problems caused by positional deviations or inconsistent angles during switching, thus improving the docking accuracy and meshing reliability between gear sets.

[0030] Both second gears 325 are rotatably mounted inside the drive box 310. Both mixing chambers 200 are provided with transmission rods 326 on their tops. One end of each transmission rod 326 extends into the drive box 310, and the two transmission rods 326 are located on opposite sides of the two second gears 325. The second gears 325 and the adjacent transmission rods 326 are connected by a pulley 327.

[0031] In this embodiment, when the first gear 324 meshes with one of the second gears 325 under the action of the switching component 320, the second gear 325 rotates accordingly and transmits power to the corresponding transmission rod 326 through the pulley 327, thereby driving the stirring component 330 in the corresponding stirring chamber 200 to perform stirring operations. By setting two second gears 325 and two corresponding transmission rods 326, the efficient switching of the driving path between the two stirring chambers 200 is achieved, which not only ensures the stability of power switching, but also avoids structural interference caused by space constraints.

[0032] The switching valve 210 is T-shaped and is located between the two mixing chambers 200 and the storage chamber 100.

[0033] In this embodiment, the switching valve 210 is configured in a T-shape and located between the two mixing chambers 200 and the storage chamber 100. It can establish a diversion connection channel between the storage chamber 100 and the two mixing chambers 200. The channel structure inside the switching valve 210 can realize the selection control of the raw material conveying direction. When the switching valve 210 is rotated to different positions, the building material slurry in the storage chamber 100 can be guided into any one of the mixing chambers 200 respectively. It should be noted that the switching valve 210 is designed with a T-shaped structure, specifically including one inlet and two outlets. The inlet is connected to the storage silo 100, and the two outlets are connected to the two mixing chambers 200 respectively. The switching valve 210 can switch channels by rotating the valve core or sliding the baffle, allowing the building material slurry in the storage silo 100 to be introduced into any of the mixing chambers 200 as needed. The valve body has an adjustable flow channel, and the switching action can be controlled by a manual knob, electric actuator, or pneumatic component. It features a compact structure, rapid response, and reliable sealing. The switching valve 210 is preferably made of wear-resistant and corrosion-resistant materials, such as stainless steel or polytetrafluoroethylene composite material, to adapt to long-term flow operations of various high-viscosity or particulate building material slurries, preventing blockage and wear. The valve body connection adopts a flange structure or a quick-locking structure for easy maintenance and replacement. The shape of the internal channel can be designed with a rounded transition according to the actual material flow rate to reduce material residue and dead corners.

[0034] like Figure 2 and Figure 4 As shown, the stirring assembly 330 includes a drive rod 331 fixedly installed at the other end of the transmission rod 326, and stirring blades 332 are fixedly installed on the outer side of the drive rod 331.

[0035] In this embodiment, during the driving process, the transmission rod 326 transmits power to the drive rod 331, which drives the stirring blade 332 to rotate, thereby achieving full mixing of the building material slurry inside the mixing chamber 200.

[0036] The stirring blade 332 is set in a spiral shape, and two drive frames 333 are fixedly mounted on the surface of the drive rod 331.

[0037] In this embodiment, the stirring blade 332 is set in a spiral shape, which can apply continuous axial propulsion force and radial tumbling force to the building material slurry during the rotation of the drive rod 331, causing the material inside the mixing chamber 200 to flow simultaneously in the up and down and inside and outside directions, thereby accelerating the mixing speed and improving the mixing uniformity. The spiral blade structure is particularly suitable for building material slurries with high viscosity or containing particulate fillers.

[0038] Scrapers 334 are fixedly installed on the bottom of the two drive frames 333, and shearing plates 335 are fixedly installed on the other side of the scrapers 334.

[0039] In this embodiment, the scraper 334 runs closely against the inner wall of the mixing chamber 200 during the mixing process, effectively removing slurry residue adhering to the chamber wall and preventing material from clumping due to long-term accumulation. Simultaneously, the shearing plate 335 is positioned on the outer side of the scraper 334, and during rotation, it can forcibly shear the passing slurry, breaking up any agglomerated materials or large particle structures, thus enhancing the crushing and dispersing function of the mixing system. The shearing plate 335 works in conjunction with the spiral-shaped mixing blades 332, ensuring both overall material tumbling and enhanced local shearing, further improving mixing uniformity and flowability. It should be noted that the shear plate 335 is designed in a comb shape, meaning that the shear plate 335 has a strip-shaped main body with multiple parallel, tooth-like comb teeth evenly arranged on one side, and the overall shape is similar to a ruler-shaped comb structure. This comb-shaped structure enables the shear plate 335 to form a multi-point contact, multi-line shearing working mode during rotation. The multiple comb teeth interweave within the flowing slurry during mixing, which can break up and disperse agglomerated materials, locally concentrated areas, or large particle structures, thereby enhancing shear strength and improving mixing uniformity.

[0040] Working principle: During use, the pre-mixed building material slurry raw materials in the storage silo 100 are guided into any one of the mixing chambers 200 via the T-shaped switching valve 210 located in the middle. The switching valve 210 can switch channels as needed, diverting the raw materials to the left or right mixing chamber 200, forming an alternating feeding mode. During mixing, the switching mixing mechanism 300 is activated. The motor 321, as the single drive source, drives the sleeve 323 to slide axially through the switching component 320 under the drive of the electric push rod 322, thereby realizing the selective switching of the first gear 324 between the two second gears 325. When the first gear 324 meshes with one of the second gears 325, power is transmitted from the second gear 325 to the transmission rod 326 at the top of the corresponding mixing chamber 200 via the pulley 327, further driving the mixing assembly 330 to rotate. The mixing assembly 330 is driven by the drive rod 331 to rotate the spiral-shaped mixing blades 332 at high speed, forming continuous axial propulsion and radial tumbling. At the same time, the two drive frames 333 on the drive rod 331 drive the scraper 334 to rotate and scrape the material along the inner wall of the mixing chamber 200, preventing material from sticking to the wall and accumulating. The comb-shaped shearing plate 335 provided on the outer side of the scraper 334 can shear and break up agglomerates and large particles formed in the slurry, improving the uniformity of mixing.

[0041] It should be noted that the motors and switching valves mentioned above are all components with relatively mature existing technologies. The specific models can be selected according to actual needs. At the same time, the motors and switching valves can be powered by built-in power supplies or by mains power. The specific power supply method should be selected according to the situation, and will not be elaborated here.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
