Description

Technical Field

[0001] This utility model relates to the field of dust collection technology in the production of inoculants, and more specifically, to a dust collection device for the production of environmentally friendly and refined inoculants. Background Technology

[0002] High-strength sulfur-oxygen inoculants can promote graphitization, reduce the tendency of white cast iron, improve the morphology and distribution of graphite, increase the number of eutectic clusters, and refine the matrix structure. In conventional ductile iron production, by adding high-strength sulfur-oxygen inoculants, the microstructure of ductile iron can be made more uniform, the tendency of shrinkage cavities is smaller, and thus the processing performance is better. In the production process of high-strength sulfur-oxygen inoculants, a screening machine is required to screen the finished product.

[0003] Currently, dust is generated during the screening of high-strength sulfur-oxygen inoculants using a screening machine, which necessitates the use of a dust collection device.

[0004] The announcement number CN220696168U proposes a dust collection device that can shake dust off the filter screen. However, manual operation is not convenient enough, and the degree of automation of dust removal needs to be improved. Utility Model Content

[0005] The purpose of this invention is to solve the problems mentioned in the background art and to propose a dust collection device for the production of environmentally friendly fine screening inoculants.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A dust collection device for the production of environmentally friendly fine screening inoculants includes a mounting frame, a collection box, a sealing door, a suction hood, a solenoid valve, a filter screen, a negative pressure dust collection assembly, and a blowing and cleaning assembly.

[0008] The collection box is fixed on the mounting frame and has a rotatable sealed door connected to it.

[0009] The suction hood is connected to the inside of the collection box via a pipeline, and a solenoid valve is installed on the pipeline.

[0010] The filter screen is installed inside the collection box and the outer side of the filter screen is in contact with the inner side of the sealing door;

[0011] The negative pressure dust collection component is connected to the inside of the collection box and is located to the right of the filter screen;

[0012] The backflushing and cleaning assembly connects to the inside of the collection box to perform a large-scale backflushing of the inside of the filter screen.

[0013] Furthermore, the mounting frame has a mounting slot, and a vertical lifting component is installed in the mounting slot. The vertical lifting component is connected to a collection box.

[0014] The above solution can achieve the lifting and lowering of the collection box through the vertical lifting component, thereby adjusting the distance between the suction hood and screening equipment of different specifications to ensure the dust collection effect. At the same time, the lowering of the collection box is also beneficial to the subsequent discharge of the inoculant.

[0015] Furthermore, the collection box is equipped with a telescopic component, which is connected to a limiting plate that contacts the inner wall of the collection box and the inner wall of the sealing door.

[0016] Furthermore, a rubber layer is provided circumferentially on the outer edge of the limiting plate, and the rubber layer is in contact with the inner wall of the collection box and the inner wall of the sealing door.

[0017] The above solution allows the limiting plate to move to the position specified in the instruction manual via a telescopic component before reverse purging and material removal. Figure 4 As shown in the diagram, the inoculant that is subsequently shed during reverse purging will accumulate between the filter and the limiting plate and will not scatter, making it easier to collect later. At the same time, the rubber layer can reduce wear between the limiting plate and the inner wall of the collection box and the inner wall of the sealing door.

[0018] Furthermore, several vibrators are connected to the limiting plate.

[0019] In the above scheme, after the limiting plate moves to the above position, several vibrators can then come into contact with the surface of the filter screen without applying force. The vibration can then further improve the shedding effect of the probiotic.

[0020] Furthermore, the negative pressure dust collection assembly includes a dust collection fan and a dust collection duct. The dust collection fan is fixed on the collection box and connected to the inside of the collection box through the dust collection duct, which is located to the right of the filter screen.

[0021] Furthermore, the purging and cleaning assembly includes an air pump, a nitrogen source, an air blowing box, and nozzles. The air pump and the nitrogen source are both fixed on the collection box. The nitrogen source is connected to the air pump, and the air pump is connected to the air blowing box fixed inside the processing box, which is equipped with several nozzles.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] Compared to existing technologies, this device can use negative pressure to absorb and collect the dust generated during the inoculant sieving process. The dust will then adhere to the filter screen. Once the collection is saturated, the inoculant can be detached by reverse air blowing. During the reverse air blowing process, the collection box is not connected to the external environment. The inoculant can then be recycled by opening the sealed door. The dust collection effect is good and the degree of automation is improved. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0032] like Figure 1 and Figure 2 As shown, a dust collection device for the production of environmentally friendly fine screening inoculants includes a mounting frame 1, a collection box 2, a sealing door 3, a suction hood 4, a solenoid valve 5, a filter screen 6, a negative pressure dust collection assembly 7, and a blowing and cleaning assembly 8.

[0033] The collection box 2 is fixed on the mounting frame 1 and a sealing door 3 is rotatably connected to the collection box 2;

[0034] The suction hood 4 is connected to the inside of the collection box 2 through a pipeline and a solenoid valve 5 (specifically a double diaphragm solenoid valve) is installed on the pipeline. The pipeline is shown in the figure without labels.

[0035] The filter screen 6 is movably installed inside the collection box 2 and the outer side of the filter screen 6 is in contact with the inner side of the sealing door 3 (specifically, the filter screen 6 is inserted into a slot fixed inside the collection box 2. The slot is not numbered in the figure. It should be noted that when the filter screen 6 is inserted into the slot and the sealing door 3 is closed, its position is limited and will not shift during subsequent filtration and back purging).

[0036] The negative pressure dust collection component 7 is connected to the inside of the collection box 2 and is located to the right of the filter screen 6;

[0037] The cleaning assembly 8 is connected to the inside of the collection box 2 to perform a large-scale backflushing of the inside of the filter screen 6.

[0038] Further refinements of the embodiments of this utility model, such as... Figure 1 As shown, the negative pressure dust collection assembly 7 includes a dust collection fan 14 and a dust collection duct 15. The dust collection fan 14 is fixed on the collection box 2 and is connected to the inside of the collection box 2 through the dust collection duct 15. The dust collection duct 15 is located to the right of the filter screen 6.

[0039] Further refinements of the embodiments of this utility model, such as... Figure 1 As shown, the purging and cleaning assembly 8 includes an air pump 16, a nitrogen source, an air blowing box 17, and nozzles 18. The air pump 16 and the nitrogen source are both fixed on the collection box 2. The nitrogen source is connected to the air pump 16, and the air pump 16 is connected to the air blowing box 17 fixed inside the processing box. Several nozzles 18 are provided on the air blowing box 17 (the nitrogen source is not shown in the figure).

[0040] It should be noted that the solenoid valve 5, the vacuum fan 14, and the air pump 16 are all electrically connected to the controller, which is not labeled in the figure.

[0041] The working process of this utility model:

[0042] First, close the sealing door 3, then control the vacuum fan 14 to work through the controller. The dust generated during the inoculant sieving process can then be sucked from the suction hood 4 into the collection box 2. Then, the powdery small particles of inoculant will adhere to the filter screen 6, and the remaining clean air will be discharged back into the surrounding air.

[0043] After the filter screen 6 has been used for a period of time, it will gradually become clogged. Then, the vacuum cleaner fan 14 will be stopped by the controller. At the same time, the solenoid valve 5 will be closed so that the collection box 2 will not be connected to the outside. Then, the air pump 16 will be controlled to work and inject nitrogen into the blowing box 17. Then, the air source will spray out from several nozzles 18 on the blowing box 17 and blow outward from the back side of the filter screen 6 so that most of the small powder particles of inoculant attached to it can be effectively removed. After the reverse blowing is completed and the inoculant has settled, the sealing door 3 will be opened to recycle the inoculant. It should be noted that the small amount of inoculant attached to the filter screen after the reverse blowing is completed is negligible and will not affect the subsequent secondary dust collection process.

[0044] Compared to existing technologies, this device can use negative pressure to absorb and collect the dust generated during the inoculant sieving process. The dust will then adhere to the filter screen. Once the collection is saturated, the inoculant can be detached by reverse air blowing. During the reverse air blowing process, the collection box is not connected to the external environment. The inoculant can then be recycled by opening the sealed door. The dust collection effect is good and the degree of automation is improved.

[0045] In some embodiments, such as Figure 3 As shown, the mounting frame 1 has a mounting slot 9, and a vertical lifting component is installed in the mounting slot 9. The vertical lifting component is connected to a collection box 2.

[0046] In a further refinement of the above embodiment, the vertical lifting component is a screw assembly 10; in this embodiment, the screw assembly 10 can be used to lift the collection box 2 and adjust the distance between the suction hood 4 and screening equipment of different specifications to ensure the dust collection effect. At the same time, the descent of the collection box 2 is also beneficial to the subsequent discharge of the inoculant.

[0047] In other embodiments, such as Figure 4 As shown, the collection box 2 is provided with a telescopic component 11, and the telescopic component 11 is connected to a limiting plate 12 that contacts the inner wall of the collection box 2 and the inner wall of the sealing door 3.

[0048] A further refinement of the above embodiment is that a rubber layer is circumferentially provided on the outer edge of the limiting plate 12, and the rubber layer is in contact with the inner wall of the collection box 2 and the inner wall of the sealing door 3. The rubber layer is not shown in the figure. In this embodiment, the limiting plate 12 can be driven to move to the position specified in the instruction manual by the telescopic member 11 before reverse purging and cleaning. Figure 4 As shown in the figure, the inoculant that is subsequently blown off by the reverse purging will accumulate between the filter screen 6 and the limiting plate 12 and will not scatter everywhere, which facilitates subsequent collection. At the same time, the rubber layer can reduce the wear between the limiting plate and the inner wall of the collection box 2 and the inner wall of the sealing door 3.

[0049] Further optimizations of the above-described embodiments, such as... Figure 5 As shown, a plurality of vibrators 13 are connected to the limiting plate 12; in this embodiment, when the limiting plate 12 moves to the above position, the plurality of vibrators 13 can then come into contact with the surface of the filter screen 6 without applying force, and the vibration can further improve the shedding effect of the probiotic.

[0050] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
