Description

Technical Field

[0001] This utility model belongs to the field of mixing device technology, and in particular relates to a mixing device for concrete waterproofing and densifying agent. Background Technology

[0002] Concrete waterproofing and densifying agent is an admixture that improves the impermeability, crack resistance, and waterproofing performance of concrete. It is used in waterproofing projects to reduce leakage. In existing technologies, the preparation of concrete waterproofing and densifying agents requires the use of a mixing device to stir and mix the raw materials. However, existing mixing devices use rotating stirring components to stir the raw materials, lacking the function of vertical stirring, resulting in poor mixing efficiency.

[0003] In existing technologies, a spiral stirring rod is used to stir the raw materials, causing the raw materials at the bottom of the mixing tank to move upwards. This method lacks pre-mixing of the raw materials, resulting in a longer mixing time and reduced stirring efficiency. Another method uses a spring and a mesh plate to block the raw materials falling into the tank. The impact of the raw materials dropped into the mesh plate through the gap causes the mesh plate to vibrate up and down, thus achieving preliminary mixing. However, this method requires an additional intermittent feeding device to provide power for the preliminary mixing of the raw materials. It fails to combine the stirring mechanism to achieve pre-mixing of the raw materials, increasing costs. Utility Model Content

[0004] The purpose of this invention is to propose a concrete waterproofing and densifying agent mixing device to solve the problem that traditional technologies require additional intermittent feeding equipment to provide power for the initial mixing of raw materials, and fail to combine with a mixing mechanism to achieve premixing of raw materials, thus increasing costs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A concrete waterproofing and densifying agent mixing device includes:

[0007] A mixing drum, the top of which is connected to a feed hopper;

[0008] A stirring mechanism, comprising a stirring motor mounted on the top of a stirring drum, the output end of the stirring motor being sealed through the stirring drum and coaxially fixedly connected to a stirring rod, and a stirring component being connected to the stirring rod;

[0009] The premix assembly includes a receiving tray connected to the top of the mixing drum. The bottom end of the feed hopper is connected to a guide pipe. The bottom end of the guide pipe is inclined and located above the receiving tray. The receiving tray is located above the mixing element and has multiple discharge ports at its bottom, which are coaxially connected to the mixing rod. A dispersing rod is fixedly connected to the mixing rod and abuts against the upper surface of the receiving tray.

[0010] Preferably, the stirring component includes a first blade and a second blade coaxially fixedly connected to the stirring rod, wherein the first blade is located at the top of the stirring rod and the second blade is located at the bottom of the stirring rod.

[0011] Preferably, both the first blade and the second blade are helical blades, and the helical output direction is directed towards the middle of the stirring rod.

[0012] Preferably, the stirring component further includes a stirring frame fixedly connected to the stirring rod, the gap between the first blade and the second blade is located inside the stirring frame, and a scraper is fixedly connected to the outside of the stirring frame. The scraper is made of rubber and the side away from the stirring frame abuts against the inner wall of the stirring drum.

[0013] Preferably, a plurality of connecting rods are fixedly connected to the top of the receiving tray, and a plurality of connecting grooves are opened in the top of the mixing drum. The plurality of connecting rods are slidably connected in the plurality of connecting grooves in a one-to-one correspondence. A buffer spring is fixedly connected between the top of the connecting rod and the top of the connecting groove. A toggle block is fixedly connected to the bottom of the dispersing rod.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In this utility model, by setting up a stirring mechanism and a premixing component, the stirring motor works and drives the stirring component to rotate through the stirring rod, so as to stir and mix the raw materials in the stirring drum; at the same time, the stirring rod drives the dispersing rod to rotate, and the dispersing rod performs preliminary stirring and mixing of the raw materials falling on the receiving tray, and evenly puts the premixed raw materials into the stirring drum, saving mixing time and improving stirring efficiency.

[0017] 2. In this utility model, by setting a buffer spring and a toggle block, when the dispersing rod rotates, it drives the toggle block to strike the edge of the discharge port. With the cooperation of the buffer spring, the receiving plate vibrates up and down, further improving the premixing effect of the raw materials in the receiving plate.

[0018] 3. In this utility model, by setting a first blade and a second blade, the rotation of the first blade can quickly convey the premixed raw materials downward, and the rotation of the second blade can convey the raw materials at the bottom of the mixing drum upward.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-4 A concrete waterproofing and densifying agent mixing device, comprising:

[0026] A mixing drum 1 is connected to a feed hopper 2 at the top.

[0027] Different raw materials are fed into the mixing drum 1 through the feed hopper 2 to prepare the concrete waterproofing and densifying agent.

[0028] The stirring mechanism includes a stirring motor 4 installed on the top of the stirring drum 1. The output end of the stirring motor 4 is sealed through the stirring drum 1 and is coaxially fixedly connected to a stirring rod 5. A stirring component is connected to the stirring rod 5.

[0029] When the stirring motor 4 is working, its output end drives the stirring rod 5 to rotate, and the stirring rod 5 drives the stirring component to rotate, thus stirring and mixing the raw materials in the stirring drum 1.

[0030] The stirring component includes a first blade 13 and a second blade 14 coaxially fixedly connected to the stirring rod 5. The first blade 13 is located at the top of the stirring rod 5, and the second blade 14 is located at the bottom of the stirring rod 5.

[0031] Both the first blade 13 and the second blade 14 are spiral blades, and the spiral output direction is directed towards the middle of the stirring rod 5.

[0032] When the first blade 13 and the second blade 14 rotate with the stirring rod 5, while mixing the raw materials inside the stirring drum 1, the first blade 13 pushes the raw materials at the top of the stirring drum 1 downwards, and the second blade 14 pushes the raw materials at the bottom of the stirring drum 1 upwards. The opposing movements of the two blades further improve the mixing effect of the raw materials, and complete the full mixing of the raw materials at the top and bottom of the stirring drum 1.

[0033] The mixing component also includes a mixing frame 15 fixedly connected to the mixing rod 5. The first blade 13 and the second blade 14 are both located inside the mixing frame 15. The mixing frame 15, in conjunction with the first blade 13 and the second blade 14, further mixes the raw materials in the mixing drum 1.

[0034] A scraper 16 is fixedly connected to the outside of the mixing frame 15. The scraper 16 is made of rubber and the side away from the mixing frame 15 abuts against the inner wall of the mixing drum 1.

[0035] When the scraper 16 rotates with the mixing frame 15, it scrapes the inner wall of the mixing drum 1, effectively preventing raw materials from adhering to the inner wall of the mixing drum 1, reducing raw material loss, and improving the discharge effect.

[0036] The premix assembly includes a receiving plate 9 connected to the top of the mixing drum. The bottom end of the feed hopper 2 is connected to a guide pipe 3. The bottom end of the guide pipe 3 is inclined and located above the receiving plate 9. The receiving plate 9 is located above the mixing component and has multiple discharge ports 10 at the bottom, which are coaxially connected to the mixing rod 5. A dispersing rod 11 is fixedly connected to the mixing rod 5 and abuts against the upper surface of the receiving plate 9.

[0037] The raw materials inside the feed hopper 2 fall into the receiving plate 9 through the guide pipe 3. When the stirring rod 5 rotates, it drives the dispersing rod 11 to rotate and sweep across the surface of the receiving plate 9, performing preliminary mixing of the raw materials falling into the receiving plate 9, and sweeping some of the raw materials into the discharge port 10, so that the raw materials fall into the mixing drum 1 through multiple discharge ports 10, performing pre-mixing treatment of the raw materials, and uniformly feeding the pre-mixed raw materials into the mixing drum 1, saving mixing time and improving mixing efficiency.

[0038] Multiple connecting rods 7 are fixedly connected to the top of the material receiving tray 9. Multiple connecting grooves 6 are opened in the top of the mixing drum 1. The multiple connecting rods 7 are slidably connected in the multiple connecting grooves 6. A buffer spring 8 is fixedly connected between the top of the connecting rod 7 and the top of the connecting groove 6. A toggle block 12 is fixedly connected to the bottom of the dispersing rod 11. The toggle block 12 is elastic, and part of the discharge port 10 is located on the rotation path of the toggle block 12.

[0039] When the dispersing rod 11 rotates, it drives the agitator 12 to sweep across the discharge port 10. The agitator 12 strikes the edge of the discharge port 10. Under the elastic force of the buffer spring 8, the receiving plate 9 vibrates up and down, further improving the premixing effect of the raw materials in the receiving plate 9.

[0040] The bottom of the mixing drum 1 is connected to a discharge pipe 17, and a valve is installed on the discharge pipe 17.

[0041] After mixing the different raw materials and preparing the concrete waterproofing and densifying agent, open the valve and discharge the prepared concrete waterproofing and densifying agent through the discharge pipe 17.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
