Description

Technical Field

[0001] This utility model relates to the field of manufactured sand processing technology, and in particular to a dewatering device for washing manufactured sand. Background Technology

[0002] Manufactured sand is rock particles with a diameter of less than 4.75mm produced by sand making machines, jaw crushers, vibrating screens, and other equipment. It does not contain soft weathered rock and belongs to the category of artificial sand.

[0003] During the processing of manufactured sand, impurities of varying degrees are often generated, so cleaning is required. After cleaning, dewatering is then carried out. Currently, commonly used dewatering equipment usually adopts a rotating cylindrical structure. After the rotating cylindrical structure is placed vertically, several water outlet holes are opened on the side wall of the cylindrical structure. During the rotation of the cylindrical structure, the manufactured sand is centrifugally dewatered through the water outlet holes.

[0004] However, in current dewatering equipment, because the manufactured sand is directly piled inside the cylindrical structure, the manufactured sand near the inner wall of the rotating cylindrical structure is dewatered faster and better than the manufactured sand in the middle of the cylindrical structure. As a result, the manufactured sand far from the inner wall of the cylindrical structure is dewatered less effectively, leading to uneven overall dewatering of the manufactured sand and affecting the dewatering effect and efficiency. Therefore, a dewatering equipment for washing manufactured sand is proposed to solve the above problems. Utility Model Content

[0010] Preferably, the conical end of the lower end of the inner cylinder is provided with a discharge port, and the discharge port is slidably connected to the end of the discharge pipe away from the inner wall of the outer cylinder, and a valve is installed on the discharge port.

[0011] Preferably, the drive assembly includes a drive motor mounted on the cover plate, the output shaft of the drive motor is fixedly connected to a gear that passes through the outer cylinder, a rack is fixedly connected to the outer surface of the upper end of the inner cylinder, and the rack and the gear are in communication with each other, and a through hole is provided on the inner wall of the upper end of the outer cylinder for the gear to move.

[0012] Preferably, a drain pipe is connected to the outer side of the lower end of the outer cylinder, and the inner bottom wall of the outer cylinder is inclined, while the drain pipe is connected to the workshop sewage pipe network.

This dewatering equipment for washing manufactured sand uses several stirring rods located on the support shaft and air outlets on the stirring rods. When the inner cylinder drives the manufactured sand to rotate, the manufactured sand is dispersed by the stirring rods during the centrifugal dewatering process, making the dewatering of the manufactured sand in the middle of the inner cylinder and near the inner wall more uniform.

[0016] 2. This dewatering equipment for washing manufactured sand uses a rotating shaft to drive the turntables on both sides to rotate. The reciprocating hinge rod pushes and pulls the shaking plate, which in turn drives the inner cylinder, cover plate, and manufactured sand inside the inner cylinder to shake back and forth. This creates gaps in the manufactured sand during the shaking process, making it easier for the water in the manufactured sand near the center of the inner cylinder to be discharged, thereby further improving the dewatering effect and efficiency of the manufactured sand.

[0022] like Figure 1-3 As shown, the present invention proposes a dewatering device for washing machined sand, including an outer cylinder 1, the upper end of the outer cylinder 1 is open, and a cover plate 2 is slidably placed at the opening. The upper surface of the cover plate 2 is provided with a feeding component 4 for feeding materials. The inner walls of the cover plate 2 and the outer cylinder 1 are equipped with dewatering components 3 for dewatering machine-made sand.

[0023] In this invention, the dewatering component 3 on the outer cylinder 1 and the cover plate 2 can break up the machine sand during the dewatering process, while hot air is uniformly conveyed to assist in dewatering.

[0024] It should be noted that the feeding component 4 includes four guide pipes 41 connected in a cross shape on the upper surface of the cover plate 2. The ends of the four guide pipes 41 away from the cover plate 2 are connected to the guide bin 42. The upper surface of the guide bin 42 is connected to the feeding hopper 43. The inner bottom wall of the guide bin 42 is a cone shape with a high center and low perimeter, so that the manufactured sand to be dewatered is fed into the guide bin 42 through the feeding hopper 43. Then, it is evenly guided into the four guide pipes 41 through the cone shape of the inner bottom wall of the guide bin 42, and then introduced into the dewatering component 3 through the guide pipes 41.

[0025] The outer side of the lower end of the outer cylinder 1 is connected to a drain pipe 5, and the inner bottom wall of the outer cylinder 1 is inclined. The drain pipe 5 is connected to the workshop sewage pipe network. The lower part of the inclined inner bottom wall of the outer cylinder 1 is close to the drain pipe 5, so that the water discharged by the dehydration component 3 is discharged through the drain pipe 5.

[0026] In an optional embodiment, the dehydration component 3 includes a support shaft 31 fixedly connected to the middle of the lower surface of the cover plate 2, and the upper end of the support shaft 31 penetrates the cover plate 2. A plurality of annularly distributed stirring rods 32 are fixedly connected to the outer surface of the support shaft 31, and a plurality of equally distributed air outlets 33 are provided below each stirring rod 32. Both the support shaft 31 and the stirring rod 32 are hollow inside, and the hollow parts of the support shaft 31 and the stirring rod 32 are connected to each other. The air outlet 33 on the stirring rod 32 is connected to its hollow part, and the end of the support shaft 31 that passes through the cover plate 2 is connected to the air guide pipe 34. The lower surface of the cover plate 2 is rotatably connected to an inner cylinder 35 that covers the outside of the stirring rod 32. The lower end of the inner cylinder 35 is conical, and the conical end of the inner cylinder 35 is slidably connected to a discharge pipe 37 that passes through the outer cylinder 1. Several permeable nets 36 are fixedly connected to the inner bottom wall of the inner cylinder 35 and are distributed in annular intervals. A support ring 38 extending into the inner wall of the outer cylinder 1 is fixedly connected to the outer surface of the lower end of the inner cylinder 35.

[0027] It should be noted that the cover plate 2 and the inner cylinder 35 are provided with a drive assembly for driving the inner cylinder 35 to rotate axially. The drive assembly drives the inner cylinder 35 to rotate axially at a uniform speed on the cover plate. The inner bottom wall of the outer cylinder 1 is provided with a drive member 6 for driving the inner cylinder 35 to reciprocate and vibrate along the vertical horizontal plane. The drive member 6 drives the inner cylinder 35 to reciprocate and vibrate up and down inside the outer cylinder 1. The lower surface of the cover plate 2 is also fixedly connected with several annularly distributed vertical rods 312, and the lower end of each vertical rod 312 is fixedly connected with a spring 313. The upper end surface of the outer cylinder 1 is provided with several grooves for the vertical rods 312 to slide, so that when the cover plate 2 shakes up and down with the inner cylinder 35, the springs 313 at the lower end of the vertical rods 312 can buffer the cover plate 2. The permeable mesh 36 is made of polypropylene (PP), and the lower end of the permeable pipe 36 covers the conical end of the inner cylinder 35. The air inlet of the air duct 34 is connected to the heat source output end, such as a hot air blower, and the hot air temperature is 200~400°C.

[0028] The inner bottom wall of the outer cylinder 1 is provided with an annular support groove for the support ring 38 to rotate. The height of the support groove from bottom to top is greater than the thickness of the support ring 38. The annular support groove allows the support ring 38 to rotate stably on the inner bottom wall of the outer cylinder 1. The support ring 38 also has room to shake up and down within the support groove.

[0029] Next, a discharge port is provided at the conical end of the lower end of the inner cylinder 35, and the discharge port is slidably connected to the end of the discharge pipe 37 away from the inner wall of the outer cylinder 1. A valve is installed on the discharge port. The valve at the discharge port of the inner cylinder 35 is used to control the discharge of the dehydrated manufactured sand in the inner cylinder 35. The discharge pipe 37 is used to discharge the manufactured sand. At the same time, since the discharge port is slidably connected to the discharge pipe 37, the discharge pipe 37 will not interfere with the up and down shaking of the inner cylinder 35.

[0030] In an optional embodiment, the drive assembly includes a drive motor 310 mounted on the cover plate 2. The output shaft of the drive motor 310 is fixedly connected to a gear 311 that passes through the outer cylinder 1. A rack 39 is fixedly connected to the outer surface of the upper end of the inner cylinder 35, and the rack 39 and the gear 311 are in communication with each other. A through hole is provided on the inner wall of the upper end of the outer cylinder 1 for the gear 311 to move.

[0031] In this embodiment, after the start-up drive motor 310 drives the gear 311 on its output shaft to rotate, it can drive the inner cylinder 35 to rotate axially at a uniform speed in the outer cylinder 1 through the meshing gear 311 and rack 39. The perforation on the outer cylinder 1 provides space for the meshing of the gear 311 and rack 39 to vibrate, and the speed of the drive motor 310 is 330~380 r / min.

[0032] In an optional embodiment, the drive unit 6 includes a dual-axis motor 61 installed in the middle of the inner bottom wall of the outer cylinder 1. The output shafts at both ends of the dual-axis motor 61 are fixedly connected to rotating shafts 66, and the ends of the two rotating shafts 66 are fixedly connected to turntables 62. Two shaking plates 64 are slidably connected to the lower surface of the support ring 38. Each turntable 62 has a hinge rod 63 rotatably connected at one end to the shaking plate 64 at its eccentric position away from the dual-axis motor 61.

[0033] In this embodiment, the shaking amplitude of the shaking plate 64 is controlled between 2 and 8 mm.

[0034] It should be noted that the upper end of the shaking plate 64 is fixedly connected to a slider 65 that extends into the inside of the support ring 38, and the slider 65 is T-shaped. The lower surface of the support ring 38 is provided with an annular groove for the slider 65 to slide, so that the upper end of the shaking plate 64 can slide stably with the support ring 38 through the cooperation of the slider 65 and the annular groove. That is, it will not interfere with the axial rotation of the support ring 38, while the support ring 38 can drive the inner cylinder 35 to shake up and down.

[0035] The working principle in the above embodiments is as follows: The manufactured sand to be dewatered is fed into the feed hopper 42 through the feed hopper 43, and then evenly guided into the four feed pipes 41 through the conical part of the bottom wall of the feed hopper 42. It is then evenly introduced into the inner cylinder 35 through the feed pipes 41. The amount of manufactured sand should not be too much, that is, it should not be flush with the opening at the top of the inner cylinder 35, but should reach two-thirds of the capacity of the inner cylinder 35. After the manufactured sand is added, the drive motor 310 and the dual-shaft motor 61 can be started respectively. The started drive motor 310 drives the inner cylinder 35 to rotate axially through the meshing gear 311 and rack 39. Several stirring rods 32 located on the support shaft 31 can disperse the manufactured sand during the centrifugal dewatering process when the inner cylinder 35 drives the manufactured sand to rotate. This creates gaps in the manufactured sand during the centrifugal dewatering process, allowing the manufactured sand in the middle to be dewatered better. This makes the dewatering of the manufactured sand in the middle and near the inner wall of the inner cylinder 35 more uniform. At the same time, hot air is delivered through the air guide pipe 34 and then blown out evenly from the accumulated manufactured sand through several air outlets 33 on the stirring rods 32. The hot air rising from bottom to top is discharged through the feeding hopper 43 to assist in dewatering. The dual-axis motor 61, once started, drives the turntables 62 on both sides to rotate via the rotating shaft 66. The reciprocating hinge rod 63 then pushes and pulls the shaking plate 64, causing the inner cylinder 35, the cover plate 2, and the manufactured sand inside the inner cylinder 35 to shake back and forth. This creates gaps in the manufactured sand during the shaking process, making it easier for the moisture in the manufactured sand near the center of the inner cylinder 35 to be discharged.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
