Description

Technical Field

[0001] The invention relates to the technical field of concrete sand and gravel drying, in particular to a concrete sand and gravel drying machine with an automatic cooling function. Background Art

[0002] Concrete sand and gravel dryer is a drying equipment that processes large amounts of materials. It is widely used in the concrete production industry due to its reliable operation, great operational flexibility, strong adaptability and large processing capacity. The common dryers on the market are generally composed of a drying drum and a support wheel. The support wheel can support the drying drum and drive it to rotate, and bearings are installed at both ends of the support wheel.

[0003] A Chinese patent discloses a concrete sand and gravel dryer (authorization announcement number CN 210773178 U). When the patented technology is working, the rotating support wheel drives the guide ring and the drying drum to rotate, and at the same time, the heat-conducting wheels at both ends of the support wheel rotate synchronously. The heat-conducting wheels contact the coolant in the cooling tank to complete heat exchange, reducing the temperature of the heat-conducting wheels, and then reducing the temperature of the support wheels and bearings, reducing maintenance costs. However, although the patent can dry the material, it cannot cool the dried material, which will affect subsequent use, and the drying effect of the patent is poor. Therefore, those skilled in the art provide a concrete sand and gravel dryer with an automatic cooling function to solve the problems raised in the above background technology.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention adopts a dual setting of a drying drum and a drying box. After the material enters the drying drum, the spiral blades are rotated by the first motor, and the drying hot air is introduced through the first drying pipe, thereby drying the material inside the drying box. At the same time, the dried material can be introduced into the drying box through the connecting pipe, and the hot air is passed through the second drying pipe to perform a secondary drying on it, which will achieve a better drying effect.

[0018] 2. It is installed inside the drying box by using the mounting plate, and a baffle is installed inside the mounting plate through a connecting shaft. When the material falls, the baffle will rotate, so that when the material drops, it will come into full contact with the hot air introduced by the second drying pipe, thereby improving the drying effect. And by the operation of the second motor, the screw can be rotated, and then the moving plate can move inside the drying box, so as to disperse the material falling on the upper surface of the conveyor belt, and thus the drying effect can be better.

[0019] 3. The cooling box can be installed by using fastening bolts. There is coolant inside the water tank. When the water pump works, the coolant will flow through the cooling pipe connected by the installation pipe, so that under the action of the cooling fan, the cooling air generated by the cooling pipe can be blown onto the material on the surface of the conveyor belt to cool the material. And through the setting of the conduit, the material can be dispersed, so that the cooling effect can be better. This setting can quickly cool the material, and has a simple structure, and can also play a circulating role. Brief Description of the Drawings

Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1 to 6 , in the embodiment of the present invention, a concrete sand and gravel dryer with an automatic cooling function includes a drying box 1. A connecting pipe 8 is provided on the upper surface of the drying box 1. The upper end of the connecting pipe 8 is connected to a drying cylinder 3. A first motor 6 is provided on one side of the drying cylinder 3. The driving end of the first motor 6 is connected to a rotating shaft 2. A spiral blade 4 is provided outside the rotating shaft 2. A first drying pipe 5 is provided above the first motor 6 on one side of the drying cylinder 3. A feed inlet is provided at a position on the upper surface of the drying cylinder 3 close to the first drying pipe 5. And the discharge port of the drying cylinder 3 is communicated with the connecting pipe 8. The present invention adopts the double setting of the drying cylinder 3 and the drying box 1. After the material enters the inside of the drying cylinder 3, the spiral blade 4 can be rotated by the operation of the first motor 6, and the drying hot air can be introduced through the first drying pipe 5, so that the material inside the drying box 1 can be dried. At the same time, the dried material can be introduced into the inside of the drying box 1 through the connecting pipe 8, and the second drying pipe 7 can pass hot air to perform secondary drying on it, which will make the drying effect better.

[0029] In Figure 1 , Figure 2 , Figure 3 and Figure 4In the dryer 1, a mounting rack 14 is installed through the interior. Inside the mounting rack 14, a conveyor belt 15 is provided. On one side of the dryer 1, a second drying pipe 7 is provided. And at a position inside the dryer 1 near the second drying pipe 7, a mounting plate 9 is installed. Inside the mounting plate 9, connecting shafts 16 are equidistantly arranged. Outside the connecting shafts 16, baffles 17 are sleeved and installed. On one side of the mounting plate 9, clamping blocks 19 are symmetrically arranged. Inside the dryer 1, clamping grooves that are engaged with the clamping blocks 19 are provided. Above the conveyor belt 15 inside the dryer 1, a moving plate 11 is provided. On the lower surface of the moving plate 11, connecting rods 10 are equidistantly arranged. At the rear surface inside the dryer 1, a second motor 21 is installed. The driving end of the second motor 21 is connected to a screw rod 18. The screw rod 18 is externally provided with the moving plate 11. At the middle position of the moving plate 11, a threaded hole 20 is provided. The connecting rods 10 are equidistantly arranged on the lower surface of the moving plate 11 at least in ten groups. And the upper surface of the connecting rods 10 is in contact with the upper surface of the conveyor belt 15. The mounting plate 9 is installed inside the dryer 1, and the baffles 17 are installed inside the mounting plate 9 through the connecting shafts 16. In this way, when the material falls, the baffles 17 will rotate, so that when the material drops, it will fully contact the hot air introduced by the second drying pipe 7, thereby improving the drying effect. And by the operation of the second motor 21, the screw rod 18 can be rotated, and then the moving plate 11 can be moved inside the dryer 1. In this way, the material that has fallen onto the upper surface of the conveyor belt 15 can be dispersed, so that the drying effect can be better.

[0030] In Figure 1 , Figure 5 and Figure 6In the Chinese version: On one side of the drying box 1, a cooling box 12 is installed outside the mounting bracket 14. A water tank 13 is arranged on one side of the cooling box 12. Fastening bolts 24 are provided on both the front surface and the rear surface of the cooling box 12. Fixing holes threadedly connected to the fastening bolts 24 are provided on both the front surface and the rear surface of the mounting bracket 14. A cooling fan 23 is arranged on the upper surface of the cooling box 12. A water pump 26 is arranged inside the water tank 13. The water outlet end of the water pump 26 is connected to a mounting pipe 27. One end of the mounting pipe 27 is connected to a cooling pipe 28. The end of the cooling pipe 28 is connected to the inside of the water tank 13. Cooling fins 25 are equidistantly arranged inside the water tank 13. A liquid level sensor is arranged inside the water tank 13 near the water pump 26. Guide pipes 29 are symmetrically arranged on the lower surface of the cooling pipe 28. The lower ends of the guide pipes 29 are in contact with the upper surface of the conveyor belt 15. The cooling pipe 28 is arranged in an "S" shape. The cooling box 12 can be installed by using the fastening bolts 24. A coolant is arranged inside the water tank 13. In this way, when the water pump 26 works, the coolant will flow through the cooling pipe 28 connected by the mounting pipe 27. Thus, under the action of the cooling fan 23, the cooling air generated by the cooling pipe 28 can be blown onto the materials on the surface of the conveyor belt 15, so as to cool the materials. And through the arrangement of the guide pipes 29, the materials can be dispersed, so that the cooling effect can be better. This setting can quickly cool the materials, and has a simple structure, and can play a circulating role at the same time.

[0031] The working principle of the present invention is as follows: When in use, the material to be dried enters through the feed port opened on the upper surface of the drying cylinder 3, and the drying hot air is introduced through the first drying pipe 5. At the same time, through the operation of the first motor 6, the rotating shaft 2 connected to the driving end of the first motor 6 can be rotated. A spiral blade 4 is arranged outside the rotating shaft 2, so that the material can be initially dried inside the drying cylinder 3. The dried material will enter the inside of the drying box 1 through the connecting pipe 8. An installation plate 9 is arranged inside the drying box 1. The installation plate 9 is engaged with the card slots opened on the inner side of the drying box 1 through the clamping blocks 19, so that the installation plate 9 can be installed. A connecting shaft 16 is arranged inside the installation plate 9, and a baffle 17 is sleeved outside the connecting shaft 16. When the material falls, the baffle 17 will be turned over, so that a part of the material falls each time. In this way, when the second drying pipe 7 introduces the drying gas into the drying box 1, the material will fully contact the drying gas when falling, making the drying effect better. And after drying, it will fall onto the conveyor belt 15. When the conveyor belt 15 is transported and the second motor 21 works, the screw 18 will rotate, and the moving plate 11 sleeved outside the screw 18 will also move. A connecting rod 10 is arranged on the lower surface of the moving plate 11, so that the material falling onto the upper surface of the conveyor belt 15 can be dispersed, making the drying effect better. After being transported by the conveyor belt 15, the material will enter the inside of the cooling box 12. A water tank 13 is arranged on one side of the cooling box 12, and a coolant is arranged inside the water tank 13. In this way, when the water pump 26 works, the coolant will flow through the cooling pipe 28 connected by the installation pipe 27. Thus, under the action of the cooling fan 23, the cooling gas generated by the cooling pipe 28 can be blown onto the material on the surface of the conveyor belt 15 to cool the material. And through the arrangement of the conduit 29, the material can be dispersed, making the cooling effect better. This setting can quickly cool the material, and has a simple structure and can play a circulating role at the same time.
