Description

Technical Field

[0001] This utility model relates to the field of conductive fine material transportation, and specifically refers to a fine particle material atomization and spraying device. Background Technology

[0002] Conductive concrete is a new type of concrete. Its basic principle is to replace some or all of the ordinary aggregate in concrete with conductive materials. It is a special type of concrete with specified electrical and mechanical properties. It possesses the ability to sense and convert heat and electricity, which makes it not only usable as a building load-bearing material, but also play an important role in antistatic applications, electric heaters, building floor heating, and road de-icing and snow melting. Therefore, research on conductive concrete has received increasingly widespread attention.

[0003] Currently, conductive materials such as graphene particles or carbon black particles are added when making conductive concrete. These fine particles are added by feeding through a conveyor belt, causing them to agglomerate in the concrete and become unevenly distributed. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a fine particulate material atomization and spraying device.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a fine particulate material atomization spraying device, comprising a feeding bin, a spiral conveying assembly connected to the feeding inlet and the feeding outlet of the feeding bin at the bottom of the feeding bin, and a nozzle assembly connected to the feeding inlet and the feeding outlet of the spiral conveying assembly for uniformly spraying conductive fine materials; the nozzle assembly includes a material storage cylinder located at the feeding end of the feeding cylinder and connected to the feeding outlet of the feeding cylinder, a nozzle located on the material storage cylinder and connected to the feeding outlet of the material storage cylinder, a blower located at the other end of the feeding cylinder, and an air supply pipe connected at one end to the air outlet of the blower and at the other end to the air inlet of the material storage cylinder.

[0006] Preferably, the spiral conveying assembly includes a feeding cylinder with an inlet connected to the outlet of the discharge bin, and a feeding screw rotatably disposed inside the feeding cylinder.

[0007] Preferably, the inner wall of the material storage cylinder is provided with a plurality of annular air guide grooves arranged at intervals and inclined towards the material storage cylinder outlet, a plurality of air outlets arranged at intervals in the plurality of annular air guide grooves, and an air supply duct that connects the air outlets with the plurality of air outlets and the air inlet with the air supply pipe.

[0008] Preferably, the diameter of the material storage cylinder gradually increases from the inlet to the outlet, forming a funnel shape.

[0009] Preferably, the air supply end of the blower is on the same axis as the feeding screw, and the feeding and air supply are driven simultaneously by an external driving device.

[0010] Preferably, the nozzle is provided with a plurality of discharge holes.

[0011] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0012] This invention utilizes a combination of a feeding hopper, a spiral conveying assembly, and a nozzle assembly to allow fine particulate materials to be fed directly from above, reducing conveying distance and time, resulting in higher efficiency. The large, well-sealed feeding hopper also minimizes material loss during conveying, saving costs and reducing environmental impact. The spiral conveying mechanism initially disperses the fine particulate material before the nozzles evenly disperse it, reducing agglomeration, solidification, and settling at the bottom, thus improving the strength and conductivity of the conductive concrete. The evenly sprayed fine particulate material achieves high dispersibility and mixing ability, enhancing the uniform distribution after mixing. Furthermore, its microporous structure enables cross-linking of cement and filler fibers, improving the overall seismic resistance, crack resistance, and corrosion resistance of the conductive concrete structure. The structure is also modular, easy to maintain, and cost-effective. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] Appendix Figure 1-3The fine particulate material atomizing and spraying device of this utility model includes a feeding bin 1, a spiral conveying assembly 2 connected to the feed inlet and the discharge outlet of the feeding bin 1, and a nozzle assembly 3 for uniformly spraying conductive fine materials through a feed inlet connected to the discharge outlet of the spiral conveying assembly 2. The nozzle assembly 3 includes a material storage cylinder 31 located at the discharge end of the feeding cylinder 21 with its feed inlet connected to the discharge outlet of the feeding cylinder 21, a nozzle 32 located on the material storage cylinder 31 and connected to its discharge outlet, a blower 33 located at the other end of the feeding cylinder 21, with one end connected to the outlet of the blower 33 and the other end connected to the inlet of the material storage cylinder 31. The air supply pipe 34; the spiral conveying assembly 2 includes a feeding cylinder 21 with the inlet connected to the outlet of the discharge bin 1, and a feeding screw 22 rotatably disposed in the feeding cylinder 21; a plurality of annular air guide grooves 35 are arranged in a ring at intervals on the inner wall of the material storage cylinder 31 and the openings are inclined towards the outlet of the material storage cylinder 31; a plurality of air outlets 36 are arranged at intervals in the plurality of annular air guide grooves 35; and an air supply duct 37 is connected to the air outlet and the plurality of air outlets 36 and the air inlet is connected to the air supply pipe 34; the air supply end of the blower 33 is on the same axis as the feeding screw 22 and is driven by an external drive device to simultaneously drive the feeding and air supply.

[0020] Furthermore, the diameter of the material storage cylinder 31 gradually increases from the inlet to the outlet, forming a funnel shape, so that the conductive fine material diffuses before being sprayed out to prevent blockage.

[0021] Furthermore, the nozzle 32 is provided with a plurality of discharge holes 4 to prevent a single discharge hole 4 from becoming blocked.

[0022] In use: First, the conductive fine material is stored in the feeding hopper 1. Then, the external drive equipment is driven to simultaneously rotate the feeding screw 22 in the feeding cylinder 21 to feed the material and the blades in the blower 33 to blow air. Then, the feeding screw 22 initially disperses the conductive fine material that falls from the feeding hopper 1 into the feeding cylinder 21 and transports the dispersed conductive fine material into the material storage cylinder 31. At the same time, the blower 33 delivers air to the material storage cylinder 31 through the air pipe 34. When the conductive fine material is transported into the material storage cylinder 31, the air sprayed from the air outlet 36 in the material storage cylinder 31 blows the conductive fine material up. Since the outlet of the annular air guide trough 35 is inclined towards the outlet of the material storage cylinder 31, the air sprayed from the air outlet 36 blows the conductive fine material toward the outlet of the material storage cylinder 31. Then, the conductive fine material is blown into the nozzle 32 by the air and sprayed evenly from several outlet holes 4 of the nozzle 32, falling onto the concrete and mixing with the concrete.

[0023] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
