Description

Technical Field

[0001] This utility model relates to the field of self-leveling cement technology, and in particular to a multi-stage mixing device for processing self-leveling cement. Background Technology

[0002] Currently, most self-leveling cement production uses a single mixing chamber structure, and its mixing mechanism is usually only a fixed type or a simple rotating type, which has obvious functional limitations.

[0003] In actual mixing processes, powder raw materials are prone to forming "fish-eye" shaped clumps due to insufficient wetting. At the same time, fixed mixing blades are difficult to effectively disrupt the laminar flow of materials, resulting in mixing dead zones and poor slurry uniformity. Conventional equipment lacks a dedicated guiding structure below the feed hopper, and the vertical impact of the mixing components on the liquid surface can easily trap air and cause powder to splash. Introducing air bubbles will directly affect the flatness and strength of the final shaped surface. To address the mixing efficiency issue, some equipment attempts to use multiple motors to drive different mixing components separately. Although this can achieve staged mixing, the structure is complex, the cost is high, and the coordination control is difficult. Utility Model Content

[0004] The purpose of this invention is to solve at least one of the technical problems existing in the prior art, and to provide a multi-stage mixing device for self-leveling cement processing. Through the sliding cooperation of the rotating rod, sliding rod, and the limiting rod with a spherical end at the top with the inclined limiting ring groove, the rotational power of a single motor is cleverly used to drive the mixing rod to generate axial reciprocating lifting and lowering motion while revolving, and to ensure that it is in an inclined downward posture when it runs under the feed hopper, thereby effectively bringing the powder into the liquid surface, avoiding material splashing and air entrainment caused by the vertical impact of the mixing rod, and fundamentally solving the problems of agglomeration and bubble formation. The large transmission wheel at the bottom of the rotating rod drives the small transmission wheel through the transmission belt, and transmits the power to another high-speed mixing plate through the bevel gear pair, forming a graded mixing system composed of the large-scale macro-mixing of the mixing rod and the high-speed local shearing of the mixing plate, which significantly improves the efficiency of breaking up powder agglomerates and dissolving polymers.

[0005] This utility model also provides a multi-stage mixing device for self-leveling cement processing, comprising: a tank body, a feed hopper at the top, a discharge port at the bottom, and a support on the lower surface;

[0006] A partition, located in the middle of the tank, divides the interior of the tank into upper and lower parts;

[0007] The drive unit is located at the top of the tank.

[0008] The stirring component is located directly above the partition and is driven by a driving component;

[0009] The precision-machined components are located directly below the partition and are driven by a drive component.

[0010] The limiting ring, located at the top of the tank, can limit the movement of the stirring components.

[0011] This utility model also has the following technical features:

[0012] In one embodiment of this utility model, the bottom end of the feed hopper is connected to the inside of the tank, the discharge port and the inside of the feed hopper are provided with valves, the side surface of the partition is fixedly connected to the inner side wall of the tank, the partition is provided with a material valve, the limiting ring is inclined, and the groove inside the limiting ring is inclined upward with one end facing the back of the tank.

[0013] In one embodiment of this utility model, the driving component includes a motor, a rotating rod, a large transmission wheel, a transmission belt, a small transmission wheel, a straight bevel gear, and a helical bevel gear. The output end of the motor is fixedly connected to the top of the rotating rod, the bottom end of the rotating rod is fixedly connected to the inner wall of the large transmission wheel, the side surfaces of the large and small transmission wheels are connected to the inner wall of the transmission belt, the lower surface of the small transmission wheel is fixedly connected to the upper surface of the straight bevel gear, and the side surface of the straight bevel gear meshes with the side surface of the helical bevel gear.

[0014] In one embodiment of this utility model, the lower surface of the motor is fixedly connected to the upper surface of the tank, the top and bottom ends of the rotating rod are rotatably connected to the top of the tank and the inner sidewall of the partition, respectively, and the large transmission wheel, transmission belt, small transmission wheel, straight bevel gear and helical bevel gear are rotatably connected to the inner sidewall of the partition.

[0015] In one embodiment of this utility model, the stirring component includes a limiting rod, a sliding rod, and a stirring rod. The side surface of the sliding rod is fixedly connected to the end of the stirring rod. The stirring rod is inclined. The top end of the sliding rod is fixedly connected to the end of the limiting rod. The end of the limiting rod away from the sliding rod is spherical, and the spherical end of the limiting rod is located inside the limiting ring.

[0016] In one embodiment of the present invention, there are several stirring rods and slide rods arranged in an array on the side surface of the rotating rod, and the inner side wall of the slide rod is slidably connected to the side surface of the rotating rod.

[0017] In one embodiment of this utility model, the fine grinding component includes a rotating shaft and a stirring plate. The end of the stirring plate is fixedly connected to the side surface of the rotating shaft, and the end of the stirring plate away from the rotating shaft will not contact the inner wall of the tank.

[0018] In one embodiment of this utility model, the end of the rotating shaft is fixedly connected to the inner wall of the helical bevel gear, and the two ends of the rotating shaft are rotatably connected to the inner wall of the partition and the bottom of the tank, respectively.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The device is equipped with a rotating rod that drives the sliding rod and the stirring rod on its side surface to rotate. Since the sliding rod and the rotating rod are slidably connected, and a spherical limiting rod is set at the top of the sliding rod, when the rotating rod drives them to rotate, the spherical end of the limiting rod will be restricted by the limiting ring. The limiting groove inside the limiting ring is inclined, which can drive the limiting rod, the sliding rod and the stirring rod to move up and down back and forth. The stirring rod is inclined so that when the stirring rod rotates to the bottom of the feed hopper, it tilts downwards to bring the added raw material into the water, without entraining air into the raw material. This prevents the stirring rod from vertically impacting the liquid surface and powder, causing material splashing, and effectively disrupts the laminar flow to ensure thorough mixing. Through the up and down movement of the inclined stirring rod, it can effectively break up powder clumps and cut polymer long chains to make them fully dissolve. Moreover, it only requires a single motor to achieve automatic lifting and stirring effect, and the structure is compact and reliable.

[0021] 2. When the motor rotates the rotating rod, the large transmission wheel at the bottom of the rotating rod can transmit the rotational power to the small transmission wheel through the transmission belt, and transmit the rotational power to the inclined rotating shaft through the straight bevel gear and the helical bevel gear, which can drive the stirring plate on its side surface to rotate. Since the large transmission wheel is larger than the small transmission wheel, the stirring plate can perform shearing and stirring of the material more quickly than the stirring rod. The staged stirring further improves the mixing effect of the material. Attached Figure Description

[0034] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0035] It should be noted that the existing multi-stage mixing equipment for self-leveling cement processing has the following core defects: air bubbles are easily trapped when the powder is added to water, resulting in agglomeration and mixing dead zones during the mixing process; a single mixing mechanism cannot simultaneously handle macroscopic mixing and microscopic shearing; and the multi-motor drive leads to complex structure and inconvenient control. To address these issues, a multi-stage mixing equipment for self-leveling cement processing is proposed, comprising: a tank 1 with a feed hopper 11 at the top, a discharge port 12 at the bottom, and a support 13 on the lower surface; a partition 2 located in the middle of the tank 1, dividing the interior of the tank 1 into upper and lower parts; a drive component 3 located at the top of the tank 1; a mixing component 4 located directly above the partition 2 and driven by the drive component 3; a fine grinding component 5 located directly below the partition 2 and driven by the drive component 3; and a limiting ring 6 located at the top of the tank 1, which can limit the movement of the mixing component 4.

[0036] In one embodiment, see Figure 1 and Figure 3 The bottom end of the feed hopper 11 is connected to the inside of the tank body 1. The discharge port 12 and the inside of the feed hopper 11 are equipped with valves 14. The side surface of the partition plate 2 is fixedly connected to the inner wall of the tank body 1. The partition plate 2 is equipped with a material valve 21. The limiting ring 6 is inclined. The groove inside the limiting ring 6 is inclined upward with one end facing the back of the tank body 1.

[0037] Specifically, it is convenient for staff to open valve 14 to inject material into tank 1 through feed hopper 11, stir on the upper surface of partition 2, and after stirring, open feed valve 21 to inject material into the lower part of partition 2 for fine stirring. Finally, open valve 14 in discharge port 12 to discharge it. The limit ring 6 can control the stirring component 4 to rotate and reciprocate.

[0038] In one embodiment, see Figure 2 The driving component 3 includes a motor 31, a rotating rod 32, a large transmission wheel 33, a transmission belt 34, a small transmission wheel 35, a straight bevel gear 36, and a helical bevel gear 37. The output end of the motor 31 is fixedly connected to the top of the rotating rod 32, the bottom end of the rotating rod 32 is fixedly connected to the inner wall of the large transmission wheel 33, the side surfaces of the large transmission wheel 33 and the small transmission wheel 35 are connected to the inner wall of the transmission belt 34, the lower surface of the small transmission wheel 35 is fixedly connected to the upper surface of the straight bevel gear 36, and the side surface of the straight bevel gear 36 is meshed with the side surface of the helical bevel gear 37.

[0039] Specifically, the starter motor 31 can rotate the rotating rod 32, which drives the large transmission wheel 33 to rotate. The rotational power is transmitted to the small transmission wheel 35 through the transmission belt 34, causing the small transmission wheel 35 to drive the straight bevel gear 36 to rotate, which in turn drives the helical bevel gear 37 to rotate. Since the large transmission wheel 33 is larger than the small transmission wheel 35, the helical bevel gear 37 can rotate rapidly.

[0040] In one embodiment, see Figure 2 and Figure 3 The lower surface of the motor 31 is fixedly connected to the upper surface of the tank 1. The top and bottom ends of the rotating rod 32 are rotatably connected to the top of the tank 1 and the inner wall of the partition 2, respectively. The large transmission wheel 33, the transmission belt 34, the small transmission wheel 35, the straight bevel gear 36 and the helical bevel gear 37 are rotatably connected to the inner wall of the partition 2.

[0041] Specifically, the motor 31 is fixed to allow the rotating rod 32, the large transmission wheel 33, the transmission belt 34, the small transmission wheel 35, the straight bevel gear 36, and the helical bevel gear 37 to rotate stably.

[0042] In one embodiment, see Figure 4 The stirring component 4 includes a limiting rod 41, a sliding rod 42, and a stirring rod 43. The side surface of the sliding rod 42 is fixedly connected to the end of the stirring rod 43. The stirring rod 43 is inclined. The top of the sliding rod 42 is fixedly connected to the end of the limiting rod 41. The end of the limiting rod 41 away from the sliding rod 42 is spherical. The spherical end of the limiting rod 41 is located inside the limiting ring 6.

[0043] Specifically, the slide rod 42 can drive the stirring rod 43 to rotate. Since the end of the limiting rod 41 away from the slide rod 42 is spherical, and the limiting groove inside the limiting ring 6 is inclined, the slide rod 42 can synchronously drive the limiting rod 41, the slide rod 42 and the stirring rod 43 to reciprocate up and down when rotating. Since the stirring rod 43 is inclined, when the stirring rod 43 rotates to directly below the feed hopper 11, it can tilt downwards to bring the raw material falling to the liquid surface into the water, without entraining air into the raw material. This prevents the stirring rod 43 from vertically impacting the liquid surface and powder, causing material splashing, and effectively disrupts the laminar flow to ensure thorough mixing. Through the up and down movement of the inclined stirring rod 43, it can effectively break up powder clumps and cut polymer long chains to make them fully dissolve.

[0044] In one embodiment, see Figure 4 The stirring rod 43 and the slide rod 42 are several and arranged in an array on the side surface of the rotating rod 32, and the inner side wall of the slide rod 42 is slidably connected to the side surface of the rotating rod 32.

[0045] Specifically, setting up several slide bars 42 and stirring rods 43 can improve the stirring efficiency of materials, allowing the rotating rod 32 to drive the slide bars 42 to rotate, and the slide bars 42 can reciprocate up and down through the limiting rod 41 and the limiting ring 6 when rotating.

[0046] In one embodiment, see Figure 2 The precision grinding component 5 includes a rotating shaft 51 and a stirring plate 52. The end of the stirring plate 52 is fixedly connected to the side surface of the rotating shaft 51, and the end of the stirring plate 52 away from the rotating shaft 51 will not contact the inner wall of the tank 1.

[0047] Specifically, the rotating shaft 51 can drive the stirring plate 52 to rotate, so as to stably stir the material inside the tank 1.

[0048] In one embodiment, see Figure 2 and Figure 3 The end of the rotating shaft 51 is fixedly connected to the inner wall of the helical bevel gear 37, and the two ends of the rotating shaft 51 are rotatably connected to the inner wall of the partition plate 2 and the bottom of the tank body 1, respectively.

[0049] Specifically, the bevel gear 37 enables the rotating shaft 51 to stir more quickly relative to the stirring rod 43, ensuring that the materials can be mixed stably.

[0050] Working Principle: When using the equipment, open valve 14 in feed hopper 11 to inject material into tank 1. Start motor 31 to rotate rotating rod 32. Rotating rod 32 drives sliding rod 42 and stirring rod 43 on its side surface to rotate. Limiting rod 41 at the top of sliding rod 42 is restricted by limiting ring 6. Since the end of limiting rod 41 away from sliding rod 42 is spherical, and the limiting groove inside limiting ring 6 is inclined, it can drive limiting rod 41, sliding rod 42 and stirring rod 43 to move up and down reciprocally. The inclined setting of stirring rod 43 can ensure that when stirring rod 43 rotates to directly below feed hopper 11, it tilts downwards to carry the raw material falling to the liquid surface into the water, preventing air from entering the raw material. This prevents stirring rod 43 from vertically impacting the liquid surface and powder, causing material splashing, and effectively disrupts laminar flow to ensure thorough mixing. The up-and-down movement of rod 43 effectively breaks up powder clumps and cuts polymer chains to ensure complete dissolution. It utilizes a single motor 31 to achieve automatic lifting and stirring, resulting in a compact and reliable structure. After initial stirring, opening the material valve 21 allows the material to flow directly below the partition plate 2. At this point, the rotating rod 32 drives the large transmission wheel 33 at its bottom to rotate. The rotational power is transmitted to the small transmission wheel 35 via the transmission belt 34, and then to the inclined rotating shaft 51 via the straight bevel gear 36 and the helical bevel gear 37. This drives the stirring plate 52 on its side surface to rotate. Because the large transmission wheel 33 is larger than the small transmission wheel 35, the stirring plate 52 can more quickly shear and stir the material relative to the stirring rod 43. This staged stirring further improves the mixing effect. Finally, opening the valve 14 inside the discharge port 12 discharges the material.

[0051] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
