Description

Technical Field

[0001] This utility model relates to the field of mixer technology, and in particular to epoxy mortar mixers. Background Technology

[0002] Epoxy colored sand is a material composed of epoxy resin and quartz sand, used in decorative projects such as tile grouting. A mixer ensures that all components of the epoxy colored sand are thoroughly and evenly mixed. This is because the quality and performance of epoxy colored sand largely depend on the uniformity of its components.

[0003] The epoxy colored sand is stirred by a mixer. The motor drives the stirring blades to stir the components of the epoxy colored sand in the mixing tank, so as to make the components of the epoxy colored sand evenly mixed and prevent uneven mixing of epoxy colored sand.

[0004] However, the components of epoxy colored sand will adhere to the inner wall of the mixing tank, and the stirring blades cannot stir the components of this part of the epoxy colored sand, which will result in uneven mixing of the epoxy colored sand components. Utility Model Content

[0005] The purpose of this invention is to address the problem in the prior art that the stirring blades cannot stir the epoxy colored sand adhering to the inner wall of the mixing tank, and to propose an epoxy mortar mixer.

[0006] The technical solution of this utility model: an epoxy mortar mixer, including a mixing tank, wherein a feed pipe is fixedly installed on the top of the mixing tank and off-center, and a forward and reverse motor is fixedly installed at the center of the top of the mixing tank;

[0007] The mixing component includes a stirring element, a chain, a spur gear, a lead screw, and a scraper ring. The stirring element is disposed inside the mixing tank. Both ends of the stirring element are fitted with chains, and the stirring element is connected to the spur gear through the chains. Both ends of the lead screw are fixedly connected to the spur gear, and the middle of the lead screw is threadedly connected to the scraper ring.

[0008] The stirring component is fixedly connected to the drive shaft of the forward and reverse rotating motor, and the outer arc surface of the scraper ring slides on the inner wall of the mixing tank.

[0009] Optionally, multiple lead screws are provided and distributed in a ring at equal angles along the inner wall of the mixing tank, and the diameter of the spur gear is longer than the diameter of the lead screw.

[0010] Optionally, the chains connected by the multiple lead screws are at different heights, and an isolation layer is fixedly installed inside the mixing tank, with the chains and spur gears located within the isolation layer.

[0011] Optionally, the mixing component includes a mixing shaft, a forward mixing blade, and a reverse mixing blade. The top end of the mixing shaft is fixedly connected to the drive shaft of a forward and reverse rotating motor. A mating gear is fixedly installed on the shaft body of the mixing shaft. The mating gear is connected to a spur gear via a chain. The forward mixing blade and the reverse mixing blade are fixedly installed in the middle of the mixing shaft. The interior of the mixing tank is filled with epoxy mortar. Both the forward mixing blade and the reverse mixing blade are in contact with the epoxy mortar inside the mixing tank.

[0012] Optionally, multiple positive and negative stirring blades are provided, and the multiple positive stirring blades and multiple negative stirring blades are distributed alternately, and the positive stirring blades and negative stirring blades have the same shape.

[0013] Optionally, the scraper ring has inclined surfaces on both the upper and lower sides, and the positive stirring blade penetrates the isolation layer and extends into the interior of the mixing tank.

[0014] Optionally, both the positive and negative stirring blades are provided with cooling components, which include a cavity groove, a guide plate, and an air pump. The air pump is fixedly installed on the top of the mixing tank. Both the positive and negative stirring blades have cavity grooves inside, and a guide plate is fixedly installed in the cavity groove. The guide plate adopts an S-shaped structure.

[0015] Optionally, the portion of the stirring shaft located within the isolation layer has an inlet, the air pump is connected to the cavity through the inlet, and an air outlet pipe is fixedly installed at the end of the guide plate.

[0016] Compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0017] This invention utilizes a reversible motor to drive the stirring shaft and spur gear to rotate, thus the lead screw drives the scraper ring to move up and down reciprocally, scraping away the epoxy colored sand component on the inner wall of the mixing tank, so that the epoxy colored sand component on the inner wall of the mixing tank participates in the stirring, thereby improving uniformity.

[0018] Furthermore, the forward and reverse motors drive the agitator to perform bidirectional mixing. During forward mixing, the epoxy mortar will gather towards the edge of the mixing tank. When mixing in reverse, this epoxy mortar gathered at the edge can be brought back to the central area, thus making the epoxy mortar evenly mixed. Moreover, due to the change in the direction of liquid flow, air bubbles have more opportunities to escape from the liquid, thereby reducing the air bubble content in the epoxy mortar and improving its quality.

[0019] Furthermore, an air pump is used to draw cold air from outside into the interior of the positive and negative mixing blades to exchange heat and reduce the temperature generated during the mixing process. This prevents excessive heat accumulation, which would accelerate the curing reaction of the epoxy mortar and render it unusable. Attached Figure Description

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0026] Example 1

[0027] This embodiment proposes an epoxy mortar mixer, such as Figure 1 As shown, it includes a mixing tank 1, a feed pipe 2 is fixedly installed on the top of the mixing tank 1 off-center, and a forward and reverse motor 3 is fixedly installed at the center of the top of the mixing tank 1.

[0028] like Figure 2 and 3 As shown, a mixing component 4 is installed inside the mixing tank 1. The mixing component 4 includes a stirring element, a chain 44, a spur gear 45, a lead screw 46, and a scraper ring 47. The stirring element is located inside the mixing tank 1, and both ends of the stirring element are fitted with chains 44. The stirring element is connected to the spur gear 45 through the chains 44. Both ends of the lead screw 46 are fixedly connected to the spur gear 45. Multiple lead screws 46 are provided and are distributed in a ring at equal angles along the inner wall of the mixing tank 1. The diameter of the spur gear 45 is longer than the diameter of the lead screw 46. The scraper ring 47 is threadedly connected to the middle of the lead screw 46. The stirring element is fixedly connected to the drive shaft of the forward and reverse reversing motor 3, and the outer arc surface of the scraper ring 47 slides on the inner wall of the mixing tank 1.

[0029] The stirring component is driven to rotate by the reversible motor 3. The stirring component uses the chain 44 and spur gear 45 to rotate the lead screw 46, thereby causing the scraper ring 47 to move along the lead screw 46. Since the reversible motor 3 can rotate in both directions, the scraper ring 47 can move up and down reciprocally to scrape off the epoxy colored sand component on the inner wall of the mixing tank 1, so that the epoxy colored sand component on the inner wall of the mixing tank 1 participates in the stirring to improve uniformity. Since the reversible motor 3 rotates in both directions, the stirring component rotates in both directions.

[0030] Bidirectional mixing can break the tendency of unidirectional aggregation. During forward mixing, epoxy mortar tends to accumulate towards the edge of mixing tank 1. When mixing in reverse, this accumulated epoxy mortar is brought back to the central area, resulting in a more uniform mixture. During mixing, unidirectional mixing easily leads to air entrainment and bubble formation. Bidirectional mixing facilitates the release of these bubbles. When bubbles are generated during forward mixing, they have a greater chance to escape from the liquid during reverse mixing due to the change in liquid flow direction, thus reducing the bubble content in the epoxy mortar and improving its quality.

[0031] Multiple lead screws 46 connect chains 44 at different heights to avoid interference between adjacent chains 44. An isolation layer 48 is fixedly installed inside the mixing tank 1. The chains 44 and spur gears 45 are located inside the isolation layer 48 to prevent epoxy mortar from contacting the chains 44.

[0032] like Figure 2 and 3 As shown, the mixing components include a mixing shaft 41, a forward mixing blade 42, and a reverse mixing blade 43. The top end of the mixing shaft 41 is fixedly connected to the drive shaft of the forward and reverse rotating motor 3. A mating gear is fixedly installed on the shaft of the mixing shaft 41, and the mating gear is connected to the end spur gear 45 via a chain 44. The forward mixing blade 42 and the reverse mixing blade 43 are fixedly installed in the middle of the mixing shaft 41. The interior of the mixing tank 1 is filled with epoxy mortar, and both the forward mixing blade 42 and the reverse mixing blade 43 are in contact with the epoxy mortar inside the mixing tank 1. Multiple forward mixing blades 42 and multiple reverse mixing blades 43 are provided, and the multiple forward mixing blades 42 and multiple reverse mixing blades 43 are staggered. The forward mixing blades 42 and the reverse mixing blades 43 have the same shape. The forward mixing blades 42 guide the epoxy mortar to flow obliquely upward, while the reverse mixing blades 43 guide the epoxy mortar to flow obliquely downward, generating convection and improving the mixing efficiency.

[0033] The scraper ring 47 has inclined surfaces on both the upper and lower sides, and the positive stirring blade 42 penetrates the isolation layer 48 and extends into the interior of the mixing tank 1. The inclined surfaces reduce the accumulation of epoxy mortar on the scraper ring 47. When scraping the epoxy mortar from the inner wall of the mixing tank 1, the epoxy mortar will flow continuously along the inclined surfaces, preventing the epoxy mortar on the scraper ring 47 from remaining stagnant and solidifying for a long time.

[0034] In this embodiment, the forward and reverse motor 3 drives the stirring shaft 41 and the spur gear 45 to rotate in both directions. Therefore, the lead screw 46 drives the scraper ring 47 to move up and down reciprocally to scrape off the epoxy colored sand component on the inner wall of the mixing tank 1, so that the epoxy colored sand component on the inner wall of the mixing tank 1 participates in the stirring to improve uniformity.

[0035] Example 2

[0036] Based on Example 1, this example proposes an epoxy mortar mixer, such as... Figure 4 As shown, both the forward stirring blade 42 and the reverse stirring blade 43 are equipped with cooling components 5. The cooling components 5 include a cavity 51, a guide plate 52, and an air pump 54. The air pump 54 is fixedly installed on the top of the mixing tank 1. Cavities 51 are formed inside both the forward stirring blade 42 and the reverse stirring blade 43, and guide plates 52 are fixedly installed at the cavities 51. The guide plates 52 have an S-shaped structure. The cavities 51 draw air from outside the mixing tank 1, allowing air to enter the stirring shaft 41, the forward stirring blade 42, and the reverse stirring blade 43, thereby reducing the temperature generated during the stirring process and preventing excessive heat accumulation, which could accelerate the curing reaction of the epoxy mortar and render it unusable.

[0037] The stirring shaft 41 located within the isolation layer 48 has an inlet 55. The air pump 54 is connected to the cavity 51 through the inlet 55. An air outlet pipe 53 is fixedly installed at the end of the guide plate 52.

[0038] The cavity 51 and the guide plate 52 work together to extend the residence time of air inside the positive stirring blade 42 and the negative stirring blade 43, so as to carry out sufficient heat exchange. During the rotation of the stirring shaft 41, the inlet 55 is always open, so the air pump 54 can draw air into the cavity 51.

[0039] In this embodiment, an air pump 54 is used to draw external cold air into the interior of the positive stirring blade 42 and the negative stirring blade 43 for heat exchange. The guide plate 52 adopts an S-shaped structure to extend the residence time of air inside the positive stirring blade 42 and the negative stirring blade 43, so as to carry out sufficient heat exchange, thereby reducing the temperature generated during the stirring process and avoiding excessive heat accumulation, which would accelerate the curing reaction speed of the epoxy mortar and make it unusable.

[0040] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
