Technical Field
[0001] The utility model relates to the field of material crushing, in particular to a fine crusher for the production of composite inoculants. Background Art
[0002] An inoculant is a substance that can promote graphitization, reduce the tendency of white mouth, improve the morphology and distribution of graphite, increase the number of eutectic groups, and refine the matrix structure. During the production process, the inoculant needs to be turned into powder, so it is necessary to crush the inoculant material into powder. Currently, most crushers used for crushing are jaw crushers. However, after the existing jaw crushers crush the material, the crushed material is usually directly discharged without screening and filtering, resulting in a relatively low overall crushing effect of the crusher and the need for manual screening of the crushed material, which greatly increases the labor intensity of the staff. Content of the Utility Model
[0003] The utility model aims to overcome the drawbacks in the above-mentioned prior art, namely, the crushed material is usually directly discharged without screening and filtering, resulting in a relatively low overall crushing effect of the crusher and the need for manual screening of the crushed material, which greatly increases the labor intensity of the staff.
[0004] A fine crusher for the production of composite inoculants is proposed, which includes a box body, a feeding port, a fixed jaw plate, a movable jaw plate, a discharging port, a second installation cavity, a storage chamber, a collection box and a pumping device. The top plate of the box body is provided with a feeding port. The fixed jaw plate and the movable jaw plate are horizontally connected inside the box body. The discharging port is opened on the bottom plate of the box body. The second installation cavity is located at the bottom of the box body. The storage chamber is located on the bottom plate inside the second installation cavity and is fixed at the discharging port position of the box body. The collection box is located on one side of the storage chamber and is fixed inside the second installation cavity. The pumping device is located on the other side of the collection box and is connected to the bottom plate inside the second installation cavity.
[0005] When the material crushed by the fixed jaw plate and the movable jaw plate falls into the interior of the storage chamber through the discharging port in this technical solution, it will first be filtered and screened by a filter plate. The inoculant that does not reach the required particle size will fall into the interior of the collection box after being guided by the filter plate, and then be pumped into the interior of the box body by the pumping device for secondary crushing to improve the overall crushing effect of the crusher. Moreover, the inoculant that has been filtered and screened by the filter plate will be conveyed outside the device by a screw conveyor after reaching the required particle size, greatly reducing the labor intensity of the staff, so as to solve the drawbacks in the above-mentioned prior art, namely, the crushed material is usually directly discharged without screening and filtering, resulting in a relatively low overall crushing effect of the crusher and the need for manual screening of the crushed material, which greatly increases the labor intensity of the staff.
[0006] For the optimization of the technical solution of the present utility model, a hinge shaft is provided at the top of the fixed jaw plate. The fixed jaw plate is hinged to the box body through the hinge shaft. The fixed jaw plate can rotate forward or backward with the hinge shaft as the center. When the fixed jaw plate rotates forward, the distance between the fixed jaw plate and the movable jaw plate becomes smaller. When the fixed jaw plate rotates backward, the distance between the fixed jaw plate and the movable jaw plate becomes larger. Correspondingly, the size of the discharge port will also be adjusted according to the position of the fixed jaw plate.
[0007] For the optimization of the technical solution of the present utility model, two adjusting cylinders are provided on the inner side plate of the box body, one above the other. The movable part at the front end of the adjusting cylinder is connected to the fixed jaw plate. When the output end of the adjusting cylinder extends forward, it will push the fixed jaw plate forward to adjust the distance between the fixed jaw plate and the movable jaw plate, so that the horizontal position of the fixed jaw plate can be adjusted according to the size of the material, thereby improving the crushing efficiency of the inoculant.
[0008] For the optimization of the technical solution of the present utility model, the storage chamber is provided with a filter plate and a screw feeder. The filter plate is horizontally fixed in the storage chamber. A notch is provided on the side plate of the storage chamber close to the collection box. The screw feeder is located at the bottom of the filter plate and is fixed on the bottom plate inside the storage chamber. The screw feeder feeds evenly, uses a variable-frequency motor for speed regulation, is flexible and suitable for the conveying requirements of the inoculant, and has a good sealing effect.
[0009] For the optimization of the technical solution of the present utility model, a valve is provided at the outlet of the screw feeder. The valve used is a butterfly valve. The butterfly valve is convenient and quick to open and close, labor-saving, has a small fluid resistance, can be operated frequently, and can achieve good sealing under low pressure, ensuring that the crushed inoculant powder will not spill out after the butterfly valve is closed.
[0010] For the optimization of the technical solution of the present utility model, the collection box is located on one side of the storage chamber, and a collection port corresponding to the notch on the side plate of the storage chamber is provided on one side plate of the collection box.
[0011] For the optimization of the technical solution of the present utility model, a weight detector is further provided on the bottom plate inside the collection box, and the weight detector is electrically connected to the pumping pump. When the weight detector detects that the inoculant inside the collection box reaches a certain weight, it starts the pumping pump to re-convey the inoculant to the inside of the device.
[0012] For the optimization of the technical solution of the present utility model, the two ends of the pumping pump are connected with a conveying pipe. One end of the conveying pipe passes through the side plate of the collection box and is connected inside the collection box. The other end of the conveying pipe passes through the box body and is arranged above the feeding port. The inoculant that does not reach the required particle diameter falls into the collection box under the action of gravity after being filtered by the filter plate, and then is re-conveyed to the position of the feeding port through the conveying pipe at the other end under the action of the pumping pump, and falls into the box body for secondary crushing.
[0013] For the optimization of the technical solution of the present utility model, universal wheels are provided at the bottom of the box body to improve the flexibility and mobility of the device, and the use position can be changed according to the usage requirements.
[0014] The beneficial effects of the present utility model compared with the prior art are as follows:
[0015] When the present utility model crushes materials, after the crushed materials are screened, they are screened in the storage chamber. The inoculant that does not reach the required particle diameter falls into the collection box and is then transported to the box body by a feeding pump for secondary crushing to improve the overall crushing effect. And after the crushed materials still pass through the screening of the filter plate, the inoculant that reaches the required particle diameter is transported out of the device by a screw conveyor, greatly reducing the labor intensity of the staff.

Detailed Description of the Invention
[0021] Next, the technical solutions in the embodiments of the present utility model will be described in detail in conjunction with the attached Figures 1-4 , in the embodiments of the present utility model.
[0022] Such as Figures 1-4As shown in the figure, a refined crusher for the production of compound inoculants includes a box body 1, a feeding port 2, a fixed jaw plate 3, a movable jaw plate 4, a discharge port 5, a second installation cavity 6, a storage chamber 7, a collection box 8 and a pumping pump 9. A feeding port 2 is opened on the top plate of the box body 1. The fixed jaw plate 3 and the movable jaw plate 4 are both horizontally arranged inside the box body 1, and the fixed jaw plate 3 and the movable jaw plate 4 are respectively located on both sides of the feeding port 2. Therefore, the inoculant put into the box body 1 through the feeding port 2 will directly fall into the crushing cavity formed by the fixed jaw plate 3 and the movable jaw plate 4 due to its own gravity.
[0023] As Figures 1-4 shown, and then after being crushed by the fixed jaw plate 3 and the movable jaw plate 4, a discharge port 5 is opened on the bottom plate of the box body 1, and the discharge port 5 and the feeding port 2 are perpendicular to each other. Therefore, the inoculant crushed by the fixed jaw plate 3 and the movable jaw plate 4 can fall out of the box body 1 due to its own gravity after reaching the required particle size. The second installation cavity 6 is located at the bottom of the box body 1, and the second installation cavity 6 is fixedly connected to the bottom plate of the box body 1 by screws. The storage chamber 7 is vertically arranged inside the second installation cavity 6 perpendicular to the discharge port 5, and the storage chamber 7 is fixedly connected to the bottom plate of the second installation cavity 6 by screws.
[0024] As Figures 1-4 shown, the collection box 8 is located on one side of the storage chamber 7 and is fixedly connected to the bottom plate of the second installation cavity 6 by screws. A notch is opened on the side plate of the storage chamber 7, and a notch is also opened at the position corresponding to the notch on the side plate of the storage chamber 7 on the collection box 8. Therefore, the inoculant with unqualified particle size falling into the storage chamber 7 can fall into the collection box 8 through the opening on the side plate of the storage chamber 7. The pumping pump 9 is located on one side of the collection box 8 and is fixedly connected to the bottom plate of the second installation cavity 6 by screws, and the feeding port of the pumping pump 9 is connected to the collection box 8 through a pipeline.
[0025] As Figures 1-4 shown, when the horizontal height of the inoculant flowing into the collection box 8 is higher than the height of the feeding port of the pumping pump 9, the pumping pump 9 can pump out the inoculant in the collection box 8 through the pipeline. A delivery pipe 91 is inserted into the outlet of the pumping pump 9. One end of the delivery pipe 91 is inserted into the pumping pump 9, and the other end of the delivery pipe 91 passes through the box body 1 and is arranged above the feeding port 2. There are two groups of adjusting cylinders 11, both of which are located inside the box body 1 and are perpendicularly arranged on the side plate of one side of the box body 1. One end of each of the two groups of adjusting cylinders 11 is hinged to the side plate of the box body 1, and the other end of each of the two groups of adjusting cylinders 11 is hinged to the fixed jaw plate 3.
[0026] As Figures 1-4As shown in the figure, a hinge shaft 31 is provided at the top of the fixed jaw plate 3. The hinge shaft 31 is fixedly connected to the fixed jaw plate 3, and the fixed jaw plate 3 is rotationally connected to the inside of the box body 1 through the hinge shaft 31 at its top. The movable jaw plate 4 is movably connected to the inside of the box body 1 through an eccentric shaft, thus forming a jaw crusher. The fixed jaw plate 3 is horizontally arranged inside the box body 1, and the top of the fixed jaw plate 3 is hinged inside the box body 1 through the hinge shaft 31. Therefore, the fixed jaw plate 3 can rotate forward or backward with the hinge shaft 31 as the center. Therefore, when the cylinder 11 is started and the output end of the cylinder 11 extends forward, the fixed jaw plate 3 will rotate counterclockwise with the hinge shaft 31 as the center under the action of the output end of the cylinder 11.
[0027] As Figures 1-4 shown, similarly, when the output end of the cylinder 11 retracts backward into the cylinder 11, the output end of the cylinder 11 will drive the fixed jaw plate 3 to rotate clockwise with the hinge shaft 31 as the center. When the output end of the cylinder 11 drives the fixed jaw plate 3 to rotate clockwise or counterclockwise, the position of the movable jaw plate 4 will not change. Therefore, when the output end of the cylinder 11 extends forward and drives the fixed jaw plate 3 to rotate counterclockwise with the hinge shaft 31 as the center, the gap of the crushing cavity between the fixed jaw plate 3 and the movable jaw plate 4 will become smaller and smaller, and the size of the discharge port 5 at the bottom of the crushing cavity will also become smaller and smaller.
[0028] As Figures 1-4 shown, similarly, when the output end of the cylinder 11 retracts backward and drives the fixed jaw plate 3 to rotate clockwise with the hinge shaft 31 as the center, the gap of the crushing cavity between the fixed jaw plate 3 and the movable jaw plate 4 will become larger and larger, and the size of the discharge port 5 at the bottom of the crushing cavity will also become larger and larger. Therefore, the particle size of the final product produced by the crusher can be controlled by adjusting the size of the discharge port 5.
[0029] As Figures 1-4 shown, the storage chamber 7 is provided with a filter plate 71 and a screw conveyor 72. The filter plate 71 is horizontally connected inside the storage chamber 7 and is clamped on the side plate of the storage chamber 7. The screw conveyor 72 is located at the bottom of the filter plate 71 and is arranged inside the storage chamber 7 in the width direction of the box body 1. The screw conveyor 72 is fixed to the bottom plate inside the storage chamber 7 by screws. A collection port 73 is opened on the side plate of the storage chamber 7 close to the collection box 8. The inoculant falling into the storage chamber 7 through the discharge port 5 will first be filtered by the filter plate 71. The inoculant with qualified particle size will pass through the filter plate 71 and fall below the filter plate 71, and then be conveyed out of the box body 1 by the screw conveyor 72.
[0030] As Figures 1-4As shown, the inoculant with unqualified particle size will fall on the filter plate 71, roll off the filter plate 71 by its own gravity, and enter the interior of the collection box 8 through the collection port 73. An electric valve 74 is provided at the outlet of the screw discharger 72, and the electric valve 74 used is a butterfly valve. When the screw discharger 72 outputs the inoculant from the box body 1, the electric valve 74 will be opened. When the screw discharger 72 stops working, the electric valve 74 will close to prevent the inoculant falling into the storage chamber 7 from falling out of the outlet. The collection box 8 is located on one side of the storage chamber 7, and a notch corresponding to the collection hole on the side plate of the storage chamber 7 is provided on the side plate of the collection box 8 close to the storage chamber 7.
[0031] As Figures 1-4 shown, a weight detector 81 is also provided on the bottom plate inside the collection box 8, and the weight detector 81 is electrically connected to the pumping pump 9. When the inoculant flowing into the collection box 8 reaches a certain amount, the weight detector 81 is triggered, and the weight detector 81 turns on the pumping pump 9 to convey the inoculant in the collection box 8 to the inside of the device through the feeding pipe for secondary crushing. Universal wheels 12 are provided at the bottom of the box body 1. Therefore, when it is necessary to move the box body 1, the position of the box body 1 can be adjusted through the universal wheels 12.
[0032] Movement process of this embodiment: Before the device is started, adjust the position of the fixed jaw plate 3 according to the usage requirements by adjusting the cylinder 11, and adjust the distance between it and the movable jaw plate 4. Then start the device. The inoculant is put into the device through the feeding port, and the jaw crusher starts to perform the crushing work. The crushed inoculant falls into the storage chamber 7 through the discharge port 5 under the action of gravity, and starts to be filtered on the filter plate 71. The inoculant that does not meet the standard falls into the collection box 8 through the collection port 73, and the inoculant that meets the standard falls into the storage chamber 7 after being filtered by the filter plate 71.
[0033] When needed, open the electric valve 74 and start the screw discharger 72 to push the inoculant out of the device. The electric valve 74 has a certain sealing property itself, so the inoculant will not spill out from the inside of the box body 1 when it is closed. When the inoculant that does not meet the standard reaches a certain amount, the weight detector 81 is triggered, and the weight detector 81 turns on the pumping pump 9 to convey the inoculant in the collection box 8 to the inside of the device through the feeding pipe for repeated crushing until the required size of the inoculant is reached.
[0034] The above embodiments are only used to illustrate the technical idea of the present invention, and the protection scope of the present invention cannot be limited by this. Any modification made on the basis of the technical solution according to the technical idea proposed by the present invention falls within the protection scope of the present invention.
