Description

Technical Field

[0001] The utility model relates to the field of sintering machine head ash processing equipment, in particular to a sintering machine head ash feeding device. Background Art

[0002] Sintering machine head ash: refers to the dust captured by the electrostatic precipitator when the sintering flue gas passes through the large flue during the sintering process.

[0003] In recent years, both the steel industry and the environmental protection industry have been looking for new ways to utilize sintering machine head ash, mainly including leaching to extract potassium chloride to make potash fertilizer, magnetic separation to select iron, flotation to extract lead, high-temperature reduction to separate iron and chloride, gravity separation + magnetic separation to extract iron, and the combined use of various processes, and have achieved some results.

[0004] At present, before the mixing process of the sintering machine head ash is carried out, the powder needs to be loaded first (the mixing is completed by a twin-shaft mixer). However, the existing loading is completed by a loader. Since the top of the twin-shaft mixer is open, dust will be generated during the loading process and a large amount of dust will overflow into the surrounding environment. In addition, after the sintering machine head ash is loaded, water needs to be injected into the twin-shaft mixer through another water supply component so that the sintering machine head ash and water are mixed and stirred into a slurry. The injection of powder and the addition of water are completed by two sets of devices, and the operation is not convenient enough. Utility Model Content

[0005] The purpose of the utility model is to solve the problems raised in the above background technology, and then proposes a sintering machine head ash feeding device.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] A sintering die head ash feeding device comprises a biaxial stirring device body, a pneumatic conveying device, a sealing plate, a first hose, a powder conveying pump, a sintering die head ash storage bin, a transmission shell, a water injection assembly, a connecting rod and a drive assembly;

[0008] The sealing plate is arranged on the feed hopper of the pneumatic conveying equipment;

[0009] One end of the first hose passes through the sealing plate and is connected to the feed hopper of the pneumatic conveying equipment, and the other end of the first hose is connected to the powder conveying pump, which is connected to the ash storage bin of the sintering machine head;

[0010] The transmission shell is connected to the end of the pneumatic conveying equipment;

[0011] The transmission shell is located above the main body of the dual-shaft mixing equipment and is consistent in size and in contact with it to reduce the amount of dust overflow during the loading process;

[0012] The water injection assembly is arranged on the transmission housing;

[0013] The two connecting rods are respectively arranged on the pneumatic conveying equipment and the transmission shell and are respectively connected to two groups of driving components arranged on the ground.

[0014] Furthermore, the water injection assembly includes a suction pump, a tee pipe, a delivery pipe, a water injection pipe and a branch pipe.

[0015] The suction pump is arranged on the transmission housing and an input end of the suction pump is connected to the water tank through a second hose;

[0016] One pipe of the tee pipe is connected to the output end of the suction pump and the remaining two pipes are connected to the delivery pipe respectively;

[0017] One end of the two delivery pipes is respectively connected to the water injection pipes symmetrically arranged inside the transmission shell;

[0018] The water injection pipe is provided with a plurality of branch pipes.

[0019] Furthermore, a plurality of nozzles are equidistantly arranged on the branch pipe.

[0020] The above solution uses an integrated water injection component on the transmission shell to directly add water to the main body of the dual-shaft mixing equipment after the powder loading is completed. A set of equipment can successively complete the two processes of loading the sintering machine head ash and adding water during the subsequent mixing process, and effectively settle the dust generated inside the transmission shell during the water adding process.

[0021] Furthermore, the driving assembly includes a ground rail and a multi-stage electric push rod.

[0022] The ground rail is slidably matched with the two connecting rods respectively;

[0023] The two multi-stage electric push rods are respectively connected to the two connecting rods.

[0024] The above solution realizes the coordinated movement of the transmission shell and the pneumatic conveying equipment through the drive component, thereby significantly reducing the amount of dust overflow during the loading process, while not hindering the subsequent maintenance and inspection of the internal components of the dual-axis mixing equipment body and the transmission shell.

[0025] Furthermore, the main body of the biaxial stirring device is symmetrically provided with a limit plate, and the inner side of the limit plate is provided with a rubber pad.

[0026] Furthermore, a distance sensor electrically connected to the multi-stage electric push rod is provided on the limit plate.

[0027] The above scheme can improve the accuracy of the movement position of the transmission shell when it blocks the top of the biaxial stirring equipment body through the limit plate, rubber pad and distance sensor. At the same time, the distance sensor can further limit the movement position of the transmission shell away from the biaxial stirring equipment body, thereby accurately limiting the reciprocating movement distance of the transmission shell.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] Compared with the existing technology, this device can significantly reduce the phenomenon of dust overflow during the process of feeding the sintering machine head ash into the double-axis mixing equipment. The transmission shell realizes effective sealing of the top of the double-axis mixing equipment and is matched with a powder conveying pump and pneumatic conveying equipment to realize automatic feeding. In addition, the feeding of the sintering machine head ash and the water adding process during the mixing process can be integrated and completed on this device, which is more convenient to operate and does not hinder the subsequent maintenance and inspection of the internal components of the double-axis mixing equipment and the transmission shell.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. The present invention is further described in conjunction with the drawings and embodiments:

[0037] The sealing plate 21 is provided on the feed hopper of the pneumatic conveying device 2;

[0038] One end of the first hose 22 passes through the sealing plate 21 and is connected to the feed hopper of the pneumatic conveying device 2. The other end of the first hose 22 is connected to the powder conveying pump, which is connected to the ash storage bin of the sintering die head (the powder conveying pump and the ash storage bin of the sintering die head are not shown in the figure);

[0039] The transmission shell 23 is connected to the end of the pneumatic conveying device 2;

[0040] The transmission shell 23 is located above the biaxial mixing equipment body 1 and is consistent in size with and in contact with it to reduce the amount of dust overflow during the loading process;

[0041] The water injection assembly is provided on the transmission housing 23;

[0042] Two connecting rods 31 are respectively arranged on the pneumatic conveying device 2 and the transmission shell 23 and are respectively connected to two groups of driving components arranged on the ground.

[0043] Further refinement of the embodiment of the present invention is as follows: Figure 1 and Figure 2 As shown, the water injection assembly includes a suction pump 24, a tee pipe 25, a delivery pipe 26, a water injection pipe 27 and a branch pipe 28.

[0044] The suction pump 24 is provided on the transmission housing 23 and the input end of the suction pump 24 is connected to the water tank (the water tank is not shown in the figure) through a second hose;

[0045] One of the three-way pipes 25 is connected to the output end of the suction pump 24 and the remaining two pipes are connected to the delivery pipe 26 respectively;

[0046] One end of the two delivery pipes 26 is respectively connected to the water injection pipes 27 symmetrically arranged inside the transmission shell 23;

[0047] The water injection pipe 27 is provided with a plurality of branch pipes 28 .

[0048] As a further optimization of the above embodiment, a plurality of nozzles are equidistantly arranged on the branch pipe 28 (the nozzles are not shown in the figure).

[0049] Further refinement of the embodiment of the present invention is as follows: Figure 1 and Figure 2 As shown, the driving assembly includes a ground rail 32 and a multi-stage electric push rod 33.

[0050] The ground rail 32 is slidably engaged with the two connecting rods 31 respectively;

[0051] The two multi-stage electric push rods 33 are respectively connected to the two connecting rods 31 .

[0052] It should be noted that the pneumatic conveying equipment 2, the powder conveying pump, the suction pump 24 and the multi-stage electric push rod 33 are all electrically connected to the controller, which is not shown in the figure.

[0053] The workflow of this utility model:

[0054] In the initial state, the controller controls the two multi-stage electric push rods 33 to move synchronously, thereby driving the transmission shell 23 to move just above the double-axis mixing equipment body 1. At this time, the transmission shell 23 contacts the upper surface of the double-axis mixing equipment body 1 to achieve sealing, and then the multi-stage electric push rod 33 stops working (in this process, since the fixed powder conveying pump is connected to the sealing plate 21 through the first hose 22, the movement of the transmission shell 23 is not hindered). Then the controller controls the powder conveying pump to work and extract the sintering machine head ash from the sintering machine head ash storage bin and inject it into the pneumatic conveying equipment 2, and then the sintering machine head Under the action of the pneumatic conveying device 2, the ash moves along its pipeline and is finally transported to the inside of the double-shaft mixing device body 1. During the process of loading the sintering head ash into the double-shaft mixing device body 1, the controller controls the double-shaft mixing device body 1 to start stirring. At the same time, the suction pump 24 is controlled to work and water can be drawn from the water tank and injected into the two water injection pipes 27 at the same time. Finally, water is sprayed outward from multiple branch pipes 28 at the same time to add water to the sintering head ash during the stirring process. At the same time, the dust generated inside the transmission shell 23 during the early feeding process can also be effectively settled during the water adding process.

[0055] When the sintering machine head ash is stirred and discharged, the controller controls the two multi-stage electric push rods 33 to move synchronously, thereby driving the transmission shell 23 to move away from the top of the double-axis mixing equipment body 1. Then, the internal components of the double-axis mixing equipment body 1 or the internal components of the transmission shell 23 can be inspected and maintained. After the maintenance is completed, a new round of sintering machine head ash processing can be started;

[0056] Compared with the existing technology, this device can significantly reduce the phenomenon of dust overflow during the process of feeding the sintering head ash into the double-axis stirring equipment. The transmission shell 23 realizes effective blocking of the top of the double-axis stirring equipment and is matched with the powder conveying pump and the pneumatic conveying equipment 2 to realize automatic feeding. In addition, the feeding of the sintering head ash and the water adding process during the stirring process can be integrated and completed on this device, which is more convenient to operate and does not hinder the subsequent maintenance and inspection of the internal parts of the double-axis stirring equipment body 1 and the internal parts of the transmission shell 23.

[0057] In some embodiments, as Figure 3 As shown, a limit plate 4 is symmetrically provided on the main body 1 of the biaxial stirring device, and a rubber pad is provided on the inner side of the limit plate 4, which is not shown in the figure;

[0058] In a further optimization of the above embodiment, a distance sensor 5 electrically connected to the multi-stage electric push rod 33 is provided on the limit plate 4; this embodiment can improve the accuracy of the movement position of the transmission shell 23 when it blocks the top of the biaxial stirring equipment body 1 through the limit plate 4, the rubber pad and the distance sensor 5. At the same time, the distance sensor 5 can also further limit the movement position of the transmission shell 23 away from the biaxial stirring equipment body 1, thereby accurately limiting the reciprocating movement distance of the transmission shell 23.
