Description

Technical Field

[0001] This invention belongs to the field of dehydration technology, and particularly relates to a material dehydrator. Background Technology

[0002] A dewatering machine is a type of washing machinery, generally used to remove water from textiles, agricultural products, and other items after washing. After dewatering, a dryer is used for further drying to achieve a thorough drying effect. Traditional dewatering machines use an electric motor to drive the inner drum at high speed. The water in the material being dewatered undergoes centrifugal motion under high-speed rotation, splashing out of the inner drum through holes around its perimeter, thus achieving dewatering. Chinese patent (CN210830298U) discloses a material dewatering machine where the material to be dewatered rises with an auger to centrifuge the water within the material. However, the contact surface between the auger and the material has no resistance, resulting in low centrifugal efficiency and overall low dewatering efficiency. Summary of the Invention

[0003] In view of this, the present invention provides a material dewatering machine that can squeeze and centrifuge the material to be dewatered, thereby improving the dewatering efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A material dewatering machine includes: a squeezing barrel, a rotary squeezing device, and a support frame. The squeezing barrel has multiple drainage holes distributed on its side wall. The rotary squeezing device includes a squeezing plate, squeezing bars, and a threaded shaft. The squeezing bars are evenly distributed circumferentially at the top of the squeezing plate. The threaded shaft is fixedly installed at the bottom of the squeezing plate. The squeezing plate is clearance-fitted with the inner wall of the squeezing barrel. The threaded shaft passes through the bottom of the squeezing barrel and is threadedly engaged with the bottom of the squeezing barrel.

[0006] Furthermore, it also includes a drive device, which includes a first motor and a turbine. The turbine is installed at the output end of the first motor and meshes with the threaded shaft. A support plate is provided on the support frame, and the first motor is installed on the support plate.

[0007] Furthermore, it also includes a feeding device, which includes a feeding funnel and a first rotating plate. A feeding port is provided on the top side wall of the extrusion barrel, and a first rotating groove is provided at the top of the extrusion barrel. The first rotating plate is slidably connected in the first rotating groove, and the feeding funnel is installed on the top side wall of the extrusion barrel, corresponding to the feeding port.

[0008] Furthermore, the feeding device also includes a second motor, a first gear, and a first rack. The second motor is installed at the top of the extrusion barrel, the first gear is installed at the output end of the second motor, and the first rack is installed on the side wall of the first rotating plate. The first gear meshes with the first rack.

[0009] Furthermore, it also includes a discharge device, which includes a discharge pipe and a second rotating plate. A discharge port is provided on the top side wall of the extrusion barrel, and a second rotating groove is provided at the top of the extrusion barrel. The second rotating plate is slidably connected in the second rotating groove, and the discharge pipe is installed on the top side wall of the extrusion barrel, corresponding to the discharge port.

[0010] Furthermore, the unloading device also includes a third motor, a second gear, and a second rack. The third motor is installed at the top of the extrusion barrel, the second gear is installed at the output end of the third motor, and the second rack is installed on the side wall of the second rotating plate. The second gear meshes with the second rack.

[0011] Furthermore, it also includes a water receiving bucket, which is fixedly installed on the outside of the extrusion bucket, and a drain outlet is provided on the bottom side wall of the water receiving bucket.

[0012] The beneficial effects of this invention are as follows:

[0013] In this invention, a threaded shaft is threadedly connected to the bottom of the extrusion barrel. Rotation of the threaded shaft drives the extrusion plate to rotate and move up and down. The rotation of the extrusion plate and the extrusion strips improve the efficiency of centrifugation of the material to be dewatered. The rising extrusion plate directly extrudes and dewaters the material, resulting in high dewatering efficiency. A second motor drives the meshing of the first gear and the first rack, causing the first rotating plate to rotate within the extrusion barrel, thus connecting the feeding hopper and the extrusion barrel for feeding. A third motor drives the meshing of the second gear and the second rack, causing the second rotating plate to rotate within the extrusion barrel, thus connecting the discharge pipe and the extrusion barrel for unloading. A water receiving bucket collects the water flowing from the extrusion barrel and discharges through the drain outlet for unified collection. Attached Figure Description

The first rotating plate 52 rotates around the center of the extrusion barrel 10 in the first rotating groove 13 at the top of the extrusion barrel 10, enabling the feeding port 12 to be opened or closed.

[0031] A material dewatering machine also includes a water receiving tank 70, which is fixedly installed on the outside of the extrusion tank 10. A drain outlet 71 is provided on the bottom side wall of the water receiving tank 70.

[0032] Example

[0033] The second motor 53 drives the first gear 54 to rotate in the forward direction. Through the meshing of the first gear 54 and the first rack 55, the first rotating plate 52 slides in the first rotating groove 13, and the feed port 12 opens. At this time, the material to be dehydrated is fed into the extrusion barrel 10 through the feed funnel 51. Then, the second motor 53 drives the first gear 54 to rotate in the reverse direction. Through the meshing of the first gear 54 and the first rack 55, the first rotating plate 52 slides in the first rotating groove 13, and the feed port 12 closes. Then, the first motor 41 drives the turbine 42 to rotate forward. The turbine 42 meshes with the threaded shaft 23, which rotates and rises at the bottom of the extrusion barrel 10, driving the extrusion plate 21 to rotate inside the extrusion barrel 10. At this time, in conjunction with the extrusion strip 22, the material to be dewatered rotates and centrifugally dewaters inside the extrusion barrel 10. The extrusion plate 21 continues to rise until it squeezes the material to be dewatered together with the top of the extrusion barrel 10. At this time, the material to be dewatered is twisted at the top of the extrusion barrel 10, resulting in high dewatering efficiency. Then, the first motor 41 rotates in the reverse direction, the turbine 42 meshes with the threaded shaft 23, and the threaded shaft 23 rotates and descends at the bottom of the extrusion barrel 10, driving the extrusion plate 21 to rotate inside the extrusion barrel 10. Within the extrusion barrel 10, as the extrusion plate 21 descends, the material to be dehydrated continues to rotate and centrifugally dehydrate within the extrusion barrel 10. After the extrusion plate 21 descends to a certain height, the first motor 41 rotates forward, repeating the centrifugal and extrusion dehydration of the material to be dehydrated during the ascent process. After the extrusion plate 21 rises or falls multiple times, the third motor 63 drives the second gear 64 to rotate forward. Through the meshing of the second gear 64 and the second rack 65, the second rotating plate 62 slides in the second rotating groove 15, opening the discharge port 14. At this time, the first motor 41 continues to rotate forward, throwing the dehydrated material out through the centrifugal action of the extrusion plate 21 and extrusion strip 22 from the discharge port 14 and discharge pipe 61. The water extracted from the material to be dehydrated within the extrusion barrel 10 by centrifugal and extrusion action enters the water receiving tank 70 through the drain hole 11 and flows out uniformly from the drain outlet 71.
