[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Example 1
[0028] In existing technologies, the fixed agitation range makes it difficult to ensure sufficient heating of sand and gravel, thus reducing drying efficiency. This embodiment provides a raw sand drying device for concrete production. Please refer to [reference needed]. Figures 1-5 This method expands the agitation range of sand and gravel, allowing the material to be fully heated, thus improving the drying effect and enhancing the quality of concrete production. The raw sand drying equipment for concrete production includes a drying cylinder 2 rotatably connected to a support 1. An electromagnetic valve is installed inside the feed inlet of the drying cylinder 2 for easy control of material entry and exit. The drying cylinder 2 is equipped with an agitation mechanism 3 for agitating the material and a feeding mechanism 4 for filtering impurities. The agitation mechanism 3 expands the agitation range and also drives the drying cylinder 2 to rotate, thereby improving the drying effect. The feeding mechanism 4 filters the material, improving the quality of concrete production.
[0029] In the concrete production process, in order to expand the range of material mixing, so that the material can be fully heated and the drying efficiency of the material can be improved, the stirring mechanism 3 includes a drive motor 31 installed on the drying cylinder 2. The output end of the drive motor 31 is connected to the stirring element 32. A toothed disc 33 is installed inside the drying cylinder 2. An installation plate 34 is installed on the stirring element 32. A rotating shaft 35 is rotatably connected to the installation plate 34. A gear 36 that meshes with the toothed disc 33 is installed on the rotating shaft 35. A connecting rod 37 is installed on the rotating shaft 35. The connecting rods 37 are symmetrically distributed on both sides inside the drying cylinder 2, thereby expanding the range of mixing of sand and gravel materials and improving the drying efficiency of sand and gravel materials. Several sets of stirring rods 38 are installed on the connecting rods 37. A self-rotating component 301 that drives the drying cylinder 2 to rotate is provided on the support 1. The operation of the drive motor 31 drives the agitator 32 to rotate, which in turn drives the mounting plate 34 to rotate. With the cooperation of the gear 36 and the gear disc 33, the rotating shaft 35 rotates, which in turn drives the connecting rod 37 to rotate. This allows the agitator 38 to fully agitate the sand and gravel material, ensuring that the sand and gravel material is fully heated and improving the drying efficiency of the sand and gravel material.
[0030] In the process of drying sand and gravel materials, in order to ensure that the sand and gravel materials are fully heated and dried, thereby improving the production quality of concrete, the self-rotating component 301 includes a rotary motor 3011 mounted on a support 1. A gear 3012 is connected to the output end of the rotary motor 3011. A gear ring 3013 meshing with the gear 3012 is mounted on the drying cylinder 2. A support ring 3014 adapted to the drying cylinder 2 is mounted on the support 1. The operation of the rotary motor 3011 drives the gear 3012 to rotate. With the connection of the gear ring 3013, the drying cylinder 2 rotates under the limiting support of the support ring 3014, thereby improving the drying efficiency of the sand and gravel materials.
[0031] Example 2
[0032] Based on Example 1, such as Figures 1-5 As shown, the existing technology has the problem that the sand and gravel are not easily heated due to the fixed agitation range, which reduces the drying efficiency. However, the existing technology does not easily filter the sand and gravel materials, which makes it easy for unwanted impurities to exist in the sand and gravel materials, thereby reducing the production quality of concrete. Therefore, the device is also equipped with a structure for filtering sand and gravel materials.
[0033] In the process of drying sand and gravel materials, in order to remove impurities from the sand and gravel materials and improve the production quality of concrete, the feeding mechanism 4 includes a connecting frame 41 installed on the support ring 3014. Two sets of dust collectors 42 are installed on the connecting frame 41, and the dust collectors 42 are symmetrically distributed on both sides of the feed inlet of the drying cylinder 2, so as to absorb the dust around the feed inlet and play a dust removal role. A feeding box 43 is installed on the connecting frame 41, and the discharge port of the feeding box 43 is at the same vertical position as the feed inlet of the drying cylinder 2. The feed box 43 is flat, facilitating precise material conveying after filtration. Two sets of guide plates 44 are installed inside the feed box 43, staggered to provide a buffering effect. Several sets of fixing components 45 are installed on the feed box 43, with buffer springs 46 connected to each component. The buffer springs 46 are symmetrically distributed in pairs at the bottom of the filter screen 47, improving the filtration effect on sand and gravel. The other end of the buffer springs 46 is connected to the filter screen 47, which is compatible with the fixing components 45. The guide plates 44 reduce the material feeding pressure, and the elasticity of the buffer springs 46 gives the filter screen 47 a certain degree of extensibility, thus filtering the sand and gravel and improving the production quality of concrete.
