Description

Technical Field

DETAILED DESCRIPTION

[0025] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] Reference Figure 1-Figure 4 A fine aggregate processing device for concrete production, comprising a shell 1 and a cooling device 2; the cooling device 2 comprises a feeding device 21, a first rotary driver 22, a transmission device 23, a sprinkler 24, a refrigerator 25, a flip device 26, a discharge device 27 and a conveying device 28; the feeding device 21 is arranged at the upper part of the shell 1, the feeding device 21 contains fine aggregate, and the feeding device 21 can quantitatively feed the fine aggregate into the shell 1; the first rotary driver 22 is arranged at one side of the feeding device 21, and the first rotary driver 22 is used to drive the feeding device 21 to operate; the conveying device 28 is arranged below the feeding device 21, and the conveying device 28 is arranged along the length direction of the shell 1; the transmission device The two sides of 23 are respectively connected to the first rotary driver 22 and the conveying device 28, and the first rotary driver 22 drives the conveying device 28 to operate through the transmission device 23; the turning device 26 is arranged on one side of the end of the conveying device 28, and the conveying device 28 conveys the fine aggregate to the turning device 26 for turning; the sprayer 24 is arranged on the upper part of the conveying device 28, and the sprayer 24 sprays atomized water vapor on the fine aggregate in the conveying device 28; the refrigerator 25 is arranged on the upper part of the turning device 26, and the refrigerator 25 blows cold air to the turning device 26; the discharge device 27 is arranged at one end of the turning device 26 away from the conveying device 28, and the discharge device 27 is used to discharge the fine aggregate dropped out of the turning device 26.

[0027] The first rotary driver 22 is preferably a servo motor. When the device starts to run, the first rotary driver 22 is started, and the first rotary driver 22 drives the feeding device 21 to feed quantitatively. The feeding device 21 puts the fine aggregate into the conveying device 28. The first rotary driver 22 drives the conveying device 28 to run through the transmission device 23, so that the conveying device 28 conveys the fine aggregate to the turning device 26. When the fine aggregate is conveyed by the conveying device 28, the sprayer 24 sprays the fine aggregate in the conveying device 28 to make the outer surface of the fine aggregate wet. Then the conveying device 28 discharges the wet fine aggregate into the turning device 26, and the refrigerator 25 blows cold air to the turning device 26, so that the fine aggregate is gradually cooled. At the same time, the water on the surface of the fine aggregate will take away the heat of the fine aggregate itself when evaporating. The turning device 26 turns the fine aggregate, so that the fine aggregate is evenly cooled and the cooling speed can be accelerated. Then it can be discharged by the discharge device 27. It is worth noting that the discharge device 27 makes the side of the turning device 26 close to the discharge device 27 in a closed state, ensuring the cooling effect of the refrigerator 25. In this way, after the equipment is started, the fine aggregate can be discharged continuously, ensuring the output of the fine aggregate after cooling, and at the same time improving the cooling speed.

[0028] Reference Figure 3 and Figure 4 The conveying device 28 includes a conveying pipe 281, a conveying shaft 282, a spiral blade 283 and a drainage hole 284; the conveying pipe 281 is fixedly arranged inside the shell 1 along the length direction of the shell 1; the conveying shaft 282 is rotatably arranged in the conveying pipe 281 along the axial direction of the conveying pipe 281, and the first rotary driver 22 drives the conveying shaft 282 to rotate through the transmission device 23; the spiral blade 283 is fixedly arranged on the side wall of the conveying shaft 282 along the axis of the conveying shaft 282; the drainage holes 284 are evenly opened at the bottom of the conveying pipe 281 along the axis of the conveying pipe 281.

[0029] When the first rotary driver 22 is started, the first rotary driver 22 drives the conveying shaft 282 to rotate through the transmission device 23, and the conveying shaft 282 drives the spiral blade 283 to rotate. Since the feeding device 21 is a quantitative feeding, the feeding device 21 will not discharge a large amount of fine aggregate at one time, but will feed it in batches. The spiral blade 283 drives the fine aggregate to flip in the conveying pipe 281 and also makes the fine aggregate move toward the flipping device 26. The sprayer 24 sprays the atomized water vapor on the fine aggregate, and the excess water will be discharged from the drainage hole 284 at the bottom of the conveying pipe 281.

[0030] Reference Figure 3 and Figure 4The flipping device 26 includes a flipping barrel 261, a flipping shaft 2622121, a connecting rod 263 and a universal joint 264; the flipping barrel 261 is tiltably arranged on one side of the end of the conveying pipe 281; the flipping shaft 2622121 is arranged inside the flipping barrel 261 along the axis of the flipping barrel 261; the two ends of the connecting rod 263 are fixedly connected to the flipping shaft 2622121 and the flipping barrel 261 respectively; the two sides of the universal joint 264 are respectively connected to the end of the flipping shaft 2622121 and the end of the conveying shaft 282, and the conveying shaft 282 drives the flipping shaft 2622121 to rotate synchronously through the universal joint 264.

[0031] When the conveying shaft 282 rotates, the conveying shaft 282 drives the flip shaft 2622121 to rotate through the universal joint 264. Since the flip shaft 2622121 and the flip barrel 261 are fixedly connected by the connecting rod 263, when the flip shaft 2622121 rotates, the flip shaft 2622121 drives the flip barrel 261 to rotate through the connecting rod 263, so that the fine aggregate falling into the flip barrel 261 rolls. When the fine aggregate rolls in the flip barrel 261, each surface will fully contact with the cold air blown out by the refrigerator 25. The cold air will take away the moisture on the surface of the fine aggregate. As the moisture evaporates, the fine aggregate can be cooled faster.

[0032] Reference Figure 1 , Figure 4 and Figure 5 : The transmission device 23 includes a first bevel gear 231214 and a second bevel gear 232214; the first bevel gear 231214 is arranged below the first rotation driver 22 along the axis of the output shaft of the first rotation driver 22, and the first rotation driver 22 can drive the first bevel gear 231214 to rotate; the second bevel gear 232214 is rotatably arranged on one side of the first bevel gear 231214 along the length direction of the housing 1, the first bevel gear 231214 and the second bevel gear 232214 are meshed with each other, and the second bevel gear 232214 is fixedly connected to the end of the conveying shaft 282.

[0033] After the first rotary driver 22 is started, the first bevel gear 231214 is driven to rotate by the first rotary driver 22, and the second bevel gear 232214 meshing with the first bevel gear 231214 rotates, so that the conveying shaft 282 fixedly connected to the second bevel gear 232214 is driven to rotate.

[0034] Reference Figure 2 , Figure 5 , Figure 6 and Figure 7The feeding device 21 includes a fixed plate 211, a follower plate 212, a gear ring 213, a gear 214 and a feed shell 215; the feed shell 215 is vertically fixedly arranged on the upper part of the outer shell 1, and the feed shell 215 and the conveying pipe 281 are connected to each other; the fixed plate 211 is a circular structure, and the fixed plate 211 is fixedly arranged in the feed shell 215 along the axis of the feed shell 215, and a first leakage hole is provided on the fixed plate 211; the gear ring 213 is rotatably arranged on the feed shell 215 along the axis of the feed shell 215; the follower plate 212 is a circular structure, and the follower plate 212 is fixedly arranged on the inner ring of the gear ring 213 along the axis of the gear ring 213, and a second leakage hole is provided on the follower plate 212; the gear 214 is fixedly arranged on the output end of the first rotary driver 22, and the gear 214 and the gear ring 213 are meshed with each other.

[0035] When the first rotary driver 22 is started, the gear 214 is driven to rotate by the first rotary driver 22. Since the gear 214 and the gear ring 213 are meshed with each other, the gear 214 drives the gear ring 213 to rotate and causes the follower plate 212 fixed on the gear ring 213 to rotate. When the second leakage hole on the follower plate 212 intersects with the first leakage hole on the fixed plate 211, the fine aggregate above the fixed plate 211 will enter the conveying pipe 281 through the first leakage hole and the second leakage hole. When the first leakage hole and the second leakage hole do not intersect at all, the fine aggregate cannot fall into the conveying pipe 281.

[0036] Reference Figure 5 : The feeding device 21 also includes a rotating shaft 2121 and a stirring rod 2122; the rotating shaft 2121 is fixedly arranged on the upper part of the following plate 212 along the axis of the following plate 212; a plurality of stirring rods 2122 are arranged, and the stirring rods 2122 are fixedly arranged on the side wall of the rotating shaft 2121 around the axis of the rotating shaft 2121.

[0037] When the follower plate 212 is driven to rotate, the rotating shaft 2121 fixed on the follower plate 212 will also rotate, so that the stirring rod 2122 arranged on the rotating shaft 2121 will also rotate synchronously and stir the fine aggregate in the feed shell 215.

[0038] Reference Figure 1-Figure 3The discharge device 27 includes a rotating disk 271, a receiving hole 2711, a second rotating driver 272, a supporting plate 273 and a discharge hole 274; the rotating disk 271 is rotatably arranged below the lowest position of the overturning barrel 261; the second rotating driver 272 is vertically arranged on the rotating disk 271, and the second rotating driver 272 can drive the rotating disk 271 to rotate; a plurality of receiving holes 2711 are arranged, and the plurality of receiving holes 2711 are evenly arranged on the rotating disk 271 around the axis of the rotating disk 271, and the receiving holes 2711 penetrate the rotating disk 271 along the axis of the rotating disk 271; the supporting plate 273 is a circular structure, and the supporting plate 273 is located below the rotating disk 271; the discharge hole 274 is vertically penetrated and opened on the part of the supporting plate 273 located on the outside of the shell 1.

[0039] The second rotating driver 272 is preferably a servo motor, and the rotating disk 271 itself can seal one side of the outer shell 1, and can also rotate under the drive of the second rotating driver 272, so that the fine aggregate in the flip barrel 261 falls into the receiving hole 2711 on the rotating disk 271. As the rotating disk 271 rotates, the receiving hole 2711 on the rotating disk 271 is driven to rotate, and the fine aggregate in the receiving hole 2711 can be taken out of the outer shell 1. When the receiving hole 2711 and the discharge hole 274 intersect, the fine aggregate is discharged from the discharge hole 274 on the supporting plate 273.

[0040] Reference Figure 1 and Figure 3 The discharging device 27 further includes a protective plate 275; the protective plate 275 is an arc-shaped structure, and the protective plate 275 is disposed on one side of the rotating disk 271, and the protective plate 275 is used to limit the fine aggregate on the rotating disk 271 from falling into the housing 1.

[0041] If the protective plate 275 is not provided, some of the fine aggregate will not fall on the receiving hole 2711, but will slide from the rotating disk 271 into the housing 1.

[0042] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
