Description

Technical Field

[0001] This utility model relates to the field of dust removal technology for steel slag conveying, and more specifically, to a dust removal device for an environmentally friendly steel slag conveyor. Background Technology

[0002] With the rapid development of the steel industry, steel slag, as a major byproduct of steel production, has become a pressing issue in terms of its treatment and utilization. Traditional steel slag treatment methods often cause significant environmental pollution and waste substantial resources. Therefore, adopting advanced steel slag treatment technologies to achieve the recycling and reuse of steel slag resources is of great significance for promoting the sustainable development of the steel industry.

[0003] Currently, steel slag powder needs to be fed into other equipment via belt conveyors for further processing. However, a lot of dust is generated during the feeding and transportation of steel slag powder onto the belt conveyor. If not treated, this will pollute the surrounding environment, which is inconsistent with the concept of green environmental protection. Utility Model Content

[0004] The purpose of this utility model is to solve the problems mentioned in the background art and to propose an environmentally friendly dust removal device for steel slag conveyors.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A dust removal device for an environmentally friendly steel slag conveyor includes a belt conveyor body, a housing, a feeding assembly, a suction assembly, a main conveying pipe, branch conveying pipes, a first solenoid valve, a second solenoid valve, a filter assembly, a dust pump, a three-way pipe, a third solenoid valve, a fourth solenoid valve, and a connecting pipe.

[0007] The housing is mounted on the belt conveyor body and has a discharge port at its end;

[0008] The feeding assembly is mounted on the housing and communicates with the interior of the housing;

[0009] The suction assembly is arranged along the length of the housing and is distributed parallel to the conveyor belt of the belt conveyor body;

[0010] The main delivery pipe is located on the outside of the housing and is connected to the suction assembly;

[0011] The conveying branch pipe is connected to the conveying main pipe, and the conveying main pipe and the conveying branch pipe are respectively equipped with a second solenoid valve and a first solenoid valve.

[0012] The bottoms of the two filter units are respectively connected to the main conveying pipe and the branch conveying pipe;

[0013] The vacuum pump is installed on one of the filter components and is connected to two connecting pipes through a three-way pipe. A third solenoid valve and a fourth solenoid valve are installed on the two pipes of the three-way pipe, respectively.

[0014] One end of each of the two connecting pipes is connected to the top of one of the two filter components.

[0015] Furthermore, the feeding assembly includes a feeding hopper, a feeding pipe, and a powder conveying pump. The feeding hopper is provided on the housing, and the feeding hopper is connected to the powder conveying pump through the feeding pipe. The powder conveying pump is connected to the steel slag powder silo.

[0016] In the above scheme, the powder conveying pump can immediately draw powder from the steel slag powder silo, and then inject the steel slag powder from the feed hopper. Finally, the steel slag powder falls onto the conveyor belt of the belt conveyor body and moves with the conveyor belt. Due to the existence of the shell, the amount of dust drifting into the external environment can be reduced.

[0017] Furthermore, a star-shaped unloader is provided between the feed hopper and the feeding pipe.

[0018] The above solution uses a star-shaped unloader to achieve uniform feeding of steel slag powder onto the belt conveyor body.

[0019] Furthermore, the suction assembly includes a suction tube and branch tubes. The suction tube is disposed inside the housing and connected to the main delivery tube. Several branch tubes connected to the interior of the suction tube are equidistantly arranged on the suction tube.

[0020] Furthermore, the filtration assembly includes a filter box and a filter element. The bottoms of the two filter boxes fixed on the housing are respectively connected to the main conveying pipe and the branch conveying pipe, and a filter element is movably installed inside each filter box. The dust pump is installed on one of the filter boxes, and one end of the two connecting pipes is respectively connected to the top of the two filter boxes.

[0021] Furthermore, the ends of the housing and the belt conveyor body are provided with inclined discharge channels, which are connected to the discharge port.

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

[0023] Compared to existing technologies, this device can significantly reduce the amount of dust generated during the feeding of steel slag powder onto the belt conveyor and subsequent transport and transfer, which then diffuses into the external environment. At the same time, it can effectively adsorb and collect the dust, and the filter can be replaced later. Meanwhile, another set of filter components can be started during the replacement of the filter components, so the dust removal process during the steel slag transport process will not be interrupted. The dust removal effect of the steel slag powder transport equipment is excellent and the degree of pollution to the surrounding environment is greatly reduced. Attached Figure Description

[0034] The conveying branch pipe 24 is connected to the conveying main pipe 23, and the conveying main pipe 23 and the conveying branch pipe 24 are respectively equipped with a second solenoid valve and a first solenoid valve 25 (the second solenoid valve is not labeled in the figure).

[0036] The vacuum pump 34 is installed on one of the filter components and is connected to two connecting pipes 37 through a three-way pipe 35. A third solenoid valve 36 and a fourth solenoid valve (the fourth solenoid valve is shown in the figure but is not labeled) are respectively installed on the two pipes of the three-way pipe 35.

[0037] One end of each of the two connecting pipes 37 is connected to the top of the two sets of filter components.

[0038] Further refinements of the embodiments of this utility model, such as... Figure 1 As shown, the feeding assembly includes a feeding hopper 12, a feeding pipe 13, and a powder conveying pump. The feeding hopper 12 is provided on the housing 11. The feeding hopper 12 is connected to the powder conveying pump through the feeding pipe 13. The powder conveying pump is connected to the steel slag powder silo. The powder conveying pump (which is existing technology and will not be improved) and the steel slag powder silo are not shown in the figure.

[0039] In a further optimization of the above embodiment, a star-shaped unloader 14 is provided between the feed hopper 12 and the feeding pipe 13.

[0040] Further refinements of the embodiments of this utility model, such as... Figure 1 and Figure 2 As shown, the suction assembly includes a suction tube 21 and branch tubes 22. The suction tube 21 is disposed inside the housing 11 and connected to the main delivery tube 23. Several branch tubes 22 connected to the interior of the suction tube 21 are equidistantly arranged on the suction tube 21.

[0041] Further refinements of the embodiments of this utility model, such as... Figure 1 and Figure 2 As shown, the filter assembly includes a filter box 31 and a filter element 32. The bottoms of the two filter boxes 31, which are fixed on the housing 11, are respectively connected to the main conveying pipe 23 and the branch conveying pipe 24. Each filter box 31 is movably equipped with a filter element 32 (specifically a filter screen). The dust pump 34 is installed on one of the filter boxes 31. One end of each of the two connecting pipes 37 is connected to the top of the two filter boxes 31.

[0042] Further refinements of the embodiments of this utility model, such as... Figure 1 As shown, the ends of the housing 11 and the belt conveyor body 1 are provided with inclined feeding channels 3 and the feeding channels 3 are connected to the discharge port 111. This design realizes the feeding process to the feed hopper of other steel slag powder processing equipment through the feeding channels 3.

[0043] It should be noted that the powder conveying pump, the rotary valve 14, the dust pump 34, the first solenoid valve 25, the second solenoid valve, the third solenoid valve 36, and the fourth solenoid valve are all electrically connected to the controller, which is not shown in the figure.

[0044] The working process of this utility model:

[0045] First, the controller controls the powder conveying pump to work and then draws powder from the steel slag powder silo. Then, the steel slag powder is injected from the feed hopper 12. Finally, the steel slag powder falls on the conveyor belt of the belt conveyor body 1 and moves with the conveyor belt. Due to the existence of the shell 11, the amount of dust drifting into the external environment can be reduced. At the same time, the star-shaped unloader 14 can achieve uniform feeding of steel slag powder onto the belt conveyor body 1.

[0046] While the steel slag powder is being fed onto the belt conveyor, the controller controls the dust pump 34 to work. At the same time, the second solenoid valve on the main conveyor 23 is opened, the first solenoid valve 25 on the branch conveyor 24 is closed, the fourth solenoid valve on the lower side of the three-way pipe 35 is opened, and the third solenoid valve 36 on the right side of the pipe is closed. Then the dust generated during the feeding and conveying of the steel slag powder will be sucked into the filter box 31 connected to the main conveyor 23, and the dust will then adhere to the filter element 32.

[0047] After a period of dust removal process, the controller is manually operated to close the second solenoid valve on the main conveying pipe 23, open the first solenoid valve 25 on the branch conveying pipe 24, close the fourth solenoid valve on the lower side of the three-way pipe 35, and open the third solenoid valve 36 on the right side of the pipe. The dust will then be drawn into the filter box 31 connected to the branch conveying pipe 24 for dust filtration and adsorption. This ensures that the dust removal process during the conveying of steel slag powder is not interrupted. During the period of alternating dust removal in the filter box 31, the filter element 32 in the other filter box 31 can be replaced. At the same time, the filter element 32 can extend the service life of the dust pump 34. The suction power of the dust pump 34 is controllable and will not suck up the steel slag powder.

[0048] Compared with existing technologies, this device can greatly reduce the amount of dust generated during the feeding of steel slag powder onto the belt conveyor and subsequent conveying and transfer process, which is then diffused into the external environment. At the same time, it can effectively adsorb and collect the dust, and the filter element 32 can be replaced later. Meanwhile, another set of filter components can be started during the replacement of filter element 32, so the dust removal process during the steel slag conveying process will not be interrupted. The dust removal effect of the steel slag powder conveying equipment is excellent and the degree of pollution to the surrounding environment is greatly reduced.

[0049] 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.
