Description

Technical Field

[0001] The utility model relates to the technical field related to iron powder production, in particular to a cylindrical iron concentrate dehydration and filtering device. Background Art

[0002] Iron ore concentrate is the main raw material for pelletizing. It is the ore powder made by crushing, grinding and beneficiation of iron ore. The fluctuation of iron content will directly affect the quality of the finished pellets. The iron ore drying stage is actually the dehydration treatment of the iron ore concentrate after magnetic separation, which effectively removes the residual moisture in it to obtain the final iron concentrate and realize its higher economic value. In the mineral processing and metallurgical industry, iron ore concentrate is the main raw material for pelletizing. The moisture index of iron ore concentrate is related to the quality of pelletizing and has a great influence on the metallurgical properties and cost of the pellets. Therefore, a dehydration and filtration device is used to dehydrate the iron ore concentrate. However, when the existing dehydration and filtration device is used to dehydrate and filter the iron ore concentrate, the water-containing iron ore concentrate easily blocks the filter holes of the filter plate, making it impossible for water to quickly pass through the filter plate and fall, resulting in poor dehydration effect. Utility Model Content

[0003] The purpose of the utility model is to solve the problems existing in the above-mentioned background technology, and to propose a cylindrical iron ore concentrate dehydration and filtering device.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a cylindrical iron ore concentrate dehydration and filtration device, comprising a support seat and an outer cylinder, the outer cylinder is fixed in the middle of the upper surface of the support seat, a servo motor and an industrial fan are fixed inside the support seat, a sealing cover is rotatably connected to the upper back of the outer cylinder through a hinge, a blocking ring is fixed above the inner wall of the outer cylinder, a dehydration cylinder is embedded in the interior of the outer cylinder, a chassis plate is fixed at the lower interior of the dehydration cylinder, a limiting ring is fixed above the outer wall of the dehydration cylinder, an exhaust plate is embedded in the interior of the outer cylinder, a drain pipe is horizontally embedded at the lower right side of the outer cylinder, a fixing plate is fixed inside the outer cylinder, and a guide plate is fixed on the outside of the fixing plate.

[0005] Preferably, the interior of the dehydration cylinder and the interior of the disc are both provided with filter holes, the distance between the outer wall of the dehydration cylinder and the outer cylinder body is 1-2 cm, and the liquid inlet end of the drain pipe is connected to the lower interior of the dehydration cylinder.

[0006] Preferably, the interior of the outer cylinder is provided with three exhaust plates arranged vertically and equidistantly in a circular shape, and the exhaust end of the industrial fan is connected to the interior of the exhaust plate through a pipeline.

[0007] Preferably, a strip-shaped exhaust groove is provided at a vertical opening at one end of the exhaust plate close to the middle of the dehydration cylinder, and the exhaust groove is located just outside the filter hole of the exhaust plate.

[0008] Preferably, the upper outer limit ring of the blocking ring is just embedded in the inside of the blocking ring, and the upper outer wall of the dehydration cylinder is in close contact with the blocking ring.

[0009] Preferably, the interior of the outer cylinder is annular and has three fixed plates arranged vertically and equidistantly. The outer walls and bottom ends of the fixed plates and guide plates are respectively in close contact with the inner wall of the dehydration cylinder and the upper surface of the bottom plate.

[0010] 1. When the iron ore powder to be dehydrated is poured into the dehydration cylinder, the servo motor drives the dehydration cylinder to rotate and centrifugally dehydrate the iron ore powder. At this time, the iron ore powder is tightly attached to the inner wall of the dehydration cylinder due to the centrifugal force and rotates with the rotation of the dehydration cylinder. Subsequently, the iron ore powder will hit the guide plate tightly attached to the inner wall of the dehydration cylinder and fall from the inner wall of the dehydration cylinder. After that, due to the centrifugal force of the dehydration cylinder, the iron ore powder is tightly attached to the inner wall of the dehydration cylinder, which prevents the iron ore powder from being tightly attached to the filter holes of the dehydration cylinder for a long time during the dehydration process, causing the filter holes to be blocked. The separated water can quickly pass through the filter holes and fall, and the separated water will also pass through the filter holes of the bottom plate and fall, resulting in a better dehydration and filtration effect.

[0011] 2. After the dehydration of the iron ore concentrate is completed, the hot air generated by the industrial fan is blown toward the dehydration cylinder along the pipe and the exhaust plate, and the iron ore concentrate in the dehydration cylinder is heated by heating the dehydration cylinder. At this time, the servo motor drives the dehydration cylinder to rotate slowly, so that part of the hot air can pass through the filter holes in the dehydration cylinder and enter the interior of the dehydration cylinder to heat and dry the iron ore concentrate. At the same time, this part of the hot air will also blow the iron ore concentrate stuck in the filter holes out of the filter holes, thereby clearing the filter holes and further improving the drying effect of the iron ore concentrate.

[0018] Example 1, with reference to Figure 1-4 , a cylindrical iron ore concentrate dehydration and filtration device comprises a support base 1 and an outer cylinder 101, the outer cylinder 101 is fixed to the middle part of the upper surface of the support base 1, and is characterized in that a servo motor 102 and an industrial fan 103 are fixed inside the support base 1, and a sealing cover 104 is rotatably connected to the upper back of the outer cylinder 101 through a hinge, a blocking ring 2 is fixed above the inner wall of the outer cylinder 101, a dehydration cylinder 201 is embedded in the interior of the outer cylinder 101, a chassis plate 202 is fixed at the lower interior of the dehydration cylinder 201, a limiting ring 203 is fixed above the outer wall of the dehydration cylinder 201, an exhaust plate 204 is embedded in the interior of the outer cylinder 101, a drain pipe 205 is horizontally embedded at the lower right side of the outer cylinder 101, a fixing plate 3 is fixed inside the outer cylinder 101, and a guide plate 301 is fixed on the outer side of the fixing plate 3.

[0019] The interior of the dehydration cylinder 201 and the interior of the disc 202 are both provided with filter holes. The distance between the outer wall of the dehydration cylinder 201 and the outer cylinder 101 is 1-2 cm. The liquid inlet end of the drain pipe 205 is connected to the lower part of the interior of the dehydration cylinder 201.

[0020] After the water in the iron ore concentrate passes through the filter holes of the dehydration cylinder 201 and falls, it will slide along the inner wall of the dehydration cylinder 201 and be discharged through the drain pipe 205;

[0021] The interior of the outer cylinder 101 is annularly and equidistantly arranged vertically with three exhaust plates 204. The exhaust end of the industrial fan 103 is connected to the interior of the exhaust plate 204 through a pipe.

[0022] The exhaust plate 204 is provided with a strip exhaust slot at one end of the vertical opening near the middle of the dehydration cylinder 201, and the exhaust slot is just outside the filter hole of the exhaust plate 204;

[0023] The limiting ring 203 on the upper outer side of the blocking ring 2 is just embedded in the inner part of the blocking ring 2, and the upper outer wall of the dehydration cylinder 201 is in close contact with the blocking ring 2;

[0024] After the iron ore concentrate is dehydrated, the hot air generated by the industrial fan 103 is blown toward the dehydration drum 201 along the pipe and the exhaust plate 204, thereby heating the iron ore concentrate in the dehydration drum 201. At this time, the servo motor 102 drives the dehydration drum 201 to rotate slowly, so that part of the hot air can pass through the filter holes in the dehydration drum 201 and enter the interior of the dehydration drum 201 to heat and dry the iron ore concentrate. At the same time, this part of the hot air will also blow the iron ore concentrate stuck in the filter holes out of the filter holes, thereby clearing the filter holes and further improving the drying effect of the iron ore concentrate.

[0025] The limiting ring 203 on the dehydration cylinder 201 is embedded in the blocking ring 2 to prevent water from splashing onto the inner wall of the outer cylinder 101 during the dehydration process.

[0026] Example 2: Example 2 differs from Example 1 in that, in this example, the interior of the outer cylinder 101 is annular and equidistantly arranged vertically with three fixing plates 3, and the outer walls and bottom ends of the fixing plates 3 and the guide plates 301 are respectively in close contact with the inner wall of the dehydration cylinder 201 and the upper surface of the bottom plate 202;

[0027] During the process of centrifugal dehydration of the iron ore fines by driving the dehydration cylinder 201 to rotate, the iron ore fines in the dehydration cylinder 201 will be tightly attached to the inner wall of the dehydration cylinder 201 due to the centrifugal force and rotate with the rotation of the dehydration cylinder. Subsequently, the iron ore fines will hit the guide plate 301 tightly attached to the inner wall of the dehydration cylinder 201 and fall from the inner wall of the dehydration cylinder 201. After that, these fallen iron ore fines will be tightly attached to the inner wall of the dehydration cylinder 201 again due to the centrifugal force of the dehydration cylinder 201, avoiding the iron ore fines from being tightly attached to and covering the filter holes of the dehydration cylinder 201 for a long time during the dehydration process, causing the filter holes to be blocked, so that the separated water can quickly pass through the filter holes and fall, and the separated water will also pass through the filter holes of the chassis plate 202 and fall, and the dehydration and filtration effect is better.

[0028] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.
