Description

Technical Field

[0001] The invention relates to the technical field of sand making machine impellers, in particular to a high-efficiency six-cavity energy-saving impact type sand making machine impeller. Background Art

[0002] Sand making machine is widely used for the fine crushing and shaping of metal and non-metallic ores, building aggregates, artificial sand and various metal slags. The impeller is a key component of the sand making machine. The impeller made by the existing technology usually includes a cavity, in which there are components such as a dividing cone, a chute plate, a feed port, a discharge port, a throwing head, and a counter block. After the material enters the cavity through the feed port, the dividing cone in the center of the cavity evenly distributes the material to each chute plate of the impeller. Through the rotation of the impeller, the material is ejected through the chute plate and the discharge port.

[0003] The impeller of the sand making machine is the core component of the sand making machine. After the material enters the high-speed running impeller cavity of the sand making machine through the feed port, it impacts the circular impact lining at a very high speed under the action of centrifugal force, forming a crushing effect, while collision and friction between materials are generated at the same time.

[0004] The impeller of the existing sand making machine on the market is a 2-chamber or 3-chamber impeller with low output and high dust. The dividing cone is set inside the impeller with a single structure, which can only evenly divide the incoming sand and gravel, so that the material in the crushing chamber cannot be fully crushed by the cutter head and crushing wall, reducing the crushing rate and thus causing insufficient production capacity. Summary of the invention

[0005] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a high-efficiency six-chamber energy-saving impact sand making machine impeller.

[0006] The purpose of the present invention is achieved through the following technical solutions:

[0007] An efficient six-chamber energy-saving impact sand making machine impeller comprises a crushing tank, a feed barrel is arranged at the upper part of the crushing tank, a material discharge base is arranged at the lower part of the crushing tank, an impeller is arranged in the crushing tank; a feed baffle is arranged in the middle part of the feed barrel, and a feed port is arranged in the middle part of the feed baffle;

[0008] The impeller comprises an upper protective disc and a lower protective disc, six supporting bodies are fixedly arranged between the upper protective disc and the lower protective disc, the six supporting bodies are arranged in a circular array with the feed barrel as the center, and the two ends of the six supporting bodies mutually form a discharge channel;

[0009] The upper wall of the discharge channel is provided with an upper lining plate, and the lower wall is provided with a lower lining plate;

[0010] A first plate hammer is installed at one end of the support body, and a second plate hammer is installed at the other end of the support body. A first alloy cutter head and a second alloy cutter head are arranged between the first plate hammer and the six support bodies, and the second alloy cutter head is arranged close to the support body, and one side of the second plate hammer is arranged toward the first plate hammer;

[0011] A dividing cone is arranged below the feed port and is connected to the feed port via a fixing rod. The dividing cone comprises a first dividing cone and a second dividing cone. The first dividing cone is installed on the upper part of the second dividing cone, and an opening facing the second dividing cone is provided in the middle part of the first dividing cone.

[0012] A further technical solution is that a material guide plate is provided in the middle of the support body, an auxiliary material guide plate is mounted on the material guide plate, the auxiliary material guide plate extends inwardly and is fixedly connected to the support body by bolts.

[0013] A further technical solution is that a side guard plate is provided at the angle formed between the guide plate and the support body, and both ends of the side guard plate are fixedly connected to the guide plate and the support body by welding.

[0014] A further technical solution is that the upper lining plate and the upper guard plate are fixedly fitted together by bolts, and the lower lining plate and the lower guard plate are fixedly fitted together by bolts.

[0015] A further technical solution is that the outer sides of the upper guard plate and the lower guard plate are both provided with impact protrusions, and the impact protrusions are arranged in a ring array with the feed barrel as the center.

[0016] A further technical solution is that the diameter of the feed port is smaller than the inner diameter of the feed barrel.

[0017] A further technical solution is that the six support bodies are all welded and fixed to the upper guard plate and the lower guard plate.

[0018] A further technical solution is that a groove is provided on a side of the second alloy cutter head facing the second hammer.

[0019] A further technical solution is that the second alloy cutter head is shorter than the first alloy cutter head.

[0020] The present invention has the following advantages:

[0021] 1. In the present invention, when sand and stone fall onto the first dividing cone, part of the sand and stone directly fall onto the second dividing cone through the opening, and the other part falls onto the upper part of the impeller through the place other than the opening of the first dividing cone. The impact protrusion on the upper part of the impeller drives the sand and stone to rotate and hit the crushing wall, and then rebounds from the crushing wall to the alloy blade for multiple impact and crushing. By setting the first dividing cone and the second dividing cone, and opening a viewing hole facing the second dividing cone on the first dividing cone, the sand and stone can be impacted in multiple ways, increasing the impact efficiency and reducing the edge angle of the sand and stone.

[0022] 2. By changing the 3-chamber impeller to a 6-chamber impeller, the stone is thrown out by the impeller rotor and thrown onto the crushing wall, and then bounces back to hit continuously. No matter it is stone hitting stone or stone hitting iron, the number of stone hits increases, the frequency is improved, and the sand formation rate is as high as 50%. The sand formation rate of traditional sand making machines is only 20~30%. In this way, the output is increased and the efficiency is improved; when the impeller rotates one circle, the frequency of stone hitting increases, the edges and corners of the sand and gravel decrease, the round particles increase, and the particle shape is better; the sand and gravel produced by the 6-chamber impeller only needs 1 motor, while the traditional sand making machine needs 2 motors, saving about 40% of energy consumption and reducing costs; it solves the problems of low output of sand making machines, low sand formation rate, poor particle shape, unreasonable grading, high energy consumption, etc., greatly improving the performance of the equipment and improving the economic benefits and product quality of the equipment.

[0023] 3. Replace the original single-layer cutter head with a double-layer alloy cutter head, with a total of 12 alloy cutter heads. The second alloy cutter head is shorter than the first alloy cutter head, and a groove is set on the second alloy cutter head to increase the force point. When the first alloy cutter head hits the sand and gravel, the broken sand and gravel hit the second alloy cutter head close to the first alloy cutter head again, increasing the number of collisions and improving the sand-forming rate of sand and gravel.

[0037] like Figures 1 to 5 As shown, an efficient six-chamber energy-saving impact sand making machine impeller comprises a crushing tank 1, a feeding cylinder 3 is arranged on the upper part of the crushing tank 1, a material discharge base 2 is arranged on the lower part of the crushing tank 1, an impeller 100 is arranged in the crushing tank 1, and the material is fed through the feeding cylinder 3 and enters the impeller 100 from the feeding cylinder 3. Through the rotation of the impeller 100, the sand and stone entering the impeller 100 are thrown out at high speed, and the thrown sand and stone hit the crushing wall 101 at high speed to be crushed;

[0038] The impeller 100 includes an upper protective disc 5 and a lower protective disc 8, and six supporting bodies 9 are fixedly arranged between the upper protective disc 5 and the lower protective disc 8. The six supporting bodies 9 are arranged in a circular array with the feed barrel 3 as the center, and the two ends of the six supporting bodies 9 mutually form a discharge channel. Through the high-speed rotation of the impeller 100, sand and stones are thrown out from the discharge channel;

[0039] The upper wall of the discharge channel is provided with an upper lining plate 13, and the lower wall is provided with a lower lining plate 12. The upper and lower lining plates 12 are provided to prevent the sand and stones thrown out at high speed in the discharge channel from rubbing against the upper and lower guard plates 5 and 8, thereby increasing the service life of the upper and lower guard plates 8;

[0040] A first plate hammer 10 is fixedly installed at one end of the support body 9 by bolts, and a second plate hammer 11 is also fixedly installed at the other end of the support body 9 by bolts. A first alloy cutter head 15 and a second alloy cutter head 16 are arranged between the first plate hammer 10 and the six support bodies 9. The second alloy cutter head 16 is arranged close to the support body 9, and one side of the second plate hammer 11 is arranged toward the first plate hammer 10. When the impeller 100 rotates, the first plate hammer 10 first contacts and collides with the sand and stone, and then the second plate hammer 11 collides with the sand and stone. The first plate hammer 10 protects one side of the material ejection outlet, and the second plate hammer 11 protects the other side. While protecting the material ejection outlet, it also collides and crushes the sand and stone during rotation.

[0041] As a preferred embodiment, a material guide plate 14 is provided in the middle of the support body 9, and an auxiliary material guide plate 14 is installed on the material guide plate 14. The auxiliary material guide plate 14 extends inwardly and is fixedly connected to the support body 9 by bolts. Through the setting of the material guide plate 14, the sand and gravel entering the impeller 100 can be quickly guided, so that the sand and gravel can quickly enter the discharge channel and be thrown out.

[0042] As a preferred embodiment, a side guard plate 17 is provided at the angle formed between the guide plate 14 and the support body 9, and both ends of the side guard plate 17 are fixedly connected to the guide plate 14 and the support body 9 by welding. The setting of the side guard plate 17 prevents sand and stones from entering the angle formed between the guide plate 14 and the support body 9, and the side guard plate 17 is arc-shaped, and the convex surface of the arc faces the discharge channel. When the guide plate 14 guides sand and stones into the discharge channel, they can slide out along the arc surface.

[0043] As a preferred embodiment, the upper lining plate 13 is fixed to the upper guard plate 5 by bolts, and the lower lining plate 12 is fixed to the lower guard plate 8 by bolts. The upper and lower lining plates 12 are arranged to prevent the sand and stones thrown out at high speed in the discharge channel from rubbing against the upper guard plate 5 and the lower guard plate 8, thereby increasing the service life of the upper and lower guard plates 8, and are convenient for disassembly by bolt fixing.

[0044] As a preferred embodiment, the outer sides of the upper guard plate 5 and the lower guard plate 8 are both provided with impact protrusions 6, and the impact protrusions 6 are arranged in a circular array with the feed barrel 3 as the center. When the impeller 100 rotates at a high speed, the impact protrusions 6 can also collide with sand and stones. At the same time, multiple equidistant impact protrusions 6 in the circular array can also cause the impacted stones to rotate during the collision, and the high-speed rotating stones collide with the crushing wall 101 again, and the crushing effect is better.

[0045] As a preferred embodiment, a feed baffle 4 is provided in the middle of the feed barrel 3, and a feed port 7 is provided in the middle of the feed baffle to better concentrate the feed. At the same time, the feed port 7 is smaller in diameter than the feed barrel 3 to prevent the sand and stone particles entering the crushing tank 1 from splashing out through the feed port 7, causing waste of materials. At the same time, the splashed sand and stone are difficult to clean, so as to prevent an increase in the cleaning cost.

[0046] As a preferred embodiment, the six support bodies 9 are all welded and fixed to the upper guard plate 5 and the lower guard plate 8 to stabilize the components, reduce bolt fixation, and prevent the upper and lower guard plates 8 from loosening during high-speed rotation to cause accidents.

[0047] As a preferred embodiment, a groove is provided on the side of the second alloy cutter head 16 facing the second plate hammer 11 to increase the collision degree, and the second alloy cutter head 16 is shorter than the first alloy cutter head 15. When sand and stone collide with the first alloy cutter head 15, the crushed sand and stone can collide with the groove again, reducing the force-bearing area and increasing the force degree.

[0048] As a preferred embodiment, a dividing cone is arranged below the feed port 7, and the dividing cone is connected to the feed port 7 through a fixing rod 19, and the dividing cone includes a first dividing cone 181 and a second dividing cone 182, wherein the first dividing cone 181 is installed on the upper part of the second dividing cone 182, and an opening is provided in the middle part of the first dividing cone 181. When sand and gravel fall onto the first dividing cone 181, part of the sand and gravel directly falls onto the second dividing cone 182 through the opening, and the other part falls onto the upper part of the impeller 100 through the place outside the opening of the first dividing cone 181, and the sand and gravel are driven by the impact protrusion 6 on the upper part of the impeller 100 to rotate and hit the crushing wall 101, and then rebound from the crushing wall 101 to the alloy blade for multiple impact and crushing.

[0049] The working process of the present invention is as follows:

[0050] When sand and gravel fall onto the first dividing cone 181, part of the sand and gravel directly falls onto the second dividing cone 182 through the opening, and the other part falls onto the upper part of the impeller 100 through the place outside the opening of the first dividing cone 181. The sand and gravel are driven by the impact protrusion 6 on the upper part of the impeller 100 to rotate and hit the crushing wall 101, and then rebound from the crushing wall 101 to the alloy blade for multiple impact and crushing. The sand and gravel entering the impeller 100 are quickly and evenly guided into the six discharge channels through the setting of the guide plate 14, so that the sand and gravel quickly enter the discharge channel and are thrown out at high speed. The thrown sand and gravel hit the crushing wall 101 at high speed and are crushed.

[0051] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
