Description

Technical Field

[0001] This utility model relates to the field of blast furnace ironmaking production technology, specifically to a one-button pulverized coal injection device. Background Technology

[0002] One-button pulverized coal injection devices are used in blast furnace ironmaking. These devices directly inject finely ground anthracite or bituminous coal (or a mixture of both) into the blast furnace tuyeres to replace some of the metallurgical coke, providing heat and acting as a reducing agent. During operation, a blower is used to transport the pulverized coal from the preparation system to the blast furnace tuyeres. This method offers advantages such as good continuity, high capacity, and good sealing, effectively ensuring a stable supply of pulverized coal. However, blowers are typically fixed to pipes with bolts and nuts. Since these bolts and nuts are exposed to air, they are prone to oxidation and corrosion, resulting in poor sealing and significantly affecting the injection effect. This makes the device unsuitable for use and presents certain shortcomings. Therefore, we propose a one-button pulverized coal injection device. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide a one-button coal powder injection device. By setting a first mounting groove, a second mounting groove, a first rubber ring, and a second rubber ring, the device achieves the effect of sealing fasteners without affecting the use of the one-button injection device. This can delay the oxidation time of the fasteners and extend their service life. At the same time, by setting a sealing ring and sealing components, the sealing performance can be greatly improved to facilitate injection.

[0004] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0005] A one-button pulverized coal injection device, comprising:

[0006] The blowpipe is provided with several fasteners, and a first mounting groove is provided on the blowpipe;

[0007] The blower is fixedly connected to the left side of the blow pipe by fasteners, and the blower is provided with a second mounting groove;

[0008] The first rubber ring is inserted through the left side of the blowpipe;

[0009] The second rubber ring is inserted through the left part of the blow pipe, and the inner side of both the second rubber ring and the first rubber ring is provided with a groove.

[0010] A sealing ring is installed on the inner side of the fan;

[0011] A sealing assembly is located on the left side of the blowpipe.

[0012] As a preferred embodiment of the one-button coal powder injection device of this utility model, the top end of the injection pipe is provided with a conveying pipe for conveying coal powder, and the left side of the injection pipe is provided with a first circular hole and a first groove for installing a sealing component, and a plurality of the first circular holes are equidistantly distributed.

[0013] In a preferred embodiment of the one-button coal powder injection device described in this utility model, the fastener is composed of bolts and nuts.

[0014] As a preferred embodiment of the one-button coal powder injection device of this utility model, the right side of the blower is provided with a second circular hole and a second groove for installing a sealing component, and a plurality of the second circular holes are equidistantly distributed.

[0015] In a preferred embodiment of the one-button pulverized coal injection device of this utility model, the second rubber ring has the same structure as the first rubber ring, and the second rubber ring and the first rubber ring are symmetrically distributed.

[0016] As a preferred embodiment of the one-button coal powder injection device of this utility model, the sealing assembly includes a fixing ring placed on the left side of the injection pipe, a plurality of springs arranged on the left side of the fixing ring, a support ring arranged on the left side of the springs, and an O-ring bonded to the left side of the support ring.

[0017] As a preferred embodiment of the one-button coal powder injection device of this utility model, the outer side of the fixing ring is provided with handles, and the four handles are distributed in a circle.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting the first mounting groove, the second mounting groove, the first rubber ring, and the second rubber ring, the sealing effect of the fastener is achieved without affecting the use of the one-button blowing device, which can delay the oxidation time of the fastener and extend its service life. At the same time, by setting the sealing ring and sealing components, the sealing performance can be greatly improved for blowing. In use, the user can align the right side of the blower with the left side of the blowing pipe and connect them, and then pass the bolt of the fastener through the second round hole and the first round hole in sequence, and then rotate the nut to fix it. After fixing, the fastener will be in the first mounting groove. The first rubber ring is then moved horizontally into the second mounting slot until it engages with the blower pipe through the slot, thus sealing the right side of the bolt. Similarly, the second rubber ring can be moved horizontally until it engages with the blower through the slot. This seals the fasteners by using the first and second rubber rings, preventing them from coming into contact with water and dust, which would accelerate corrosion and extend their service life. Furthermore, during blower operation, the sealing rings provide initial sealing, while the spring in the sealing assembly allows the O-ring to adhere tightly to the blower, further enhancing the seal. Thus, the sealing rings and sealing assembly significantly improve the sealing performance for blower operation. Attached Figure Description

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0037] This utility model provides a one-button coal powder injection device. By setting a first mounting groove, a second mounting groove, a first rubber ring, and a second rubber ring, it achieves the effect of sealing fasteners without affecting the use of the one-button injection device. This can delay the oxidation time of the fasteners and extend their service life. At the same time, by setting a sealing ring and sealing components, the sealing performance can be greatly improved to facilitate injection.

[0038] Figure 1-6 The diagram shown is an overall structural schematic of one embodiment of the pulverized coal one-button injection device of this utility model. Please refer to [link / reference]. Figure 1-6 The main body of a one-button pulverized coal injection device according to this embodiment includes: injection pipe 100, blower 200, first rubber ring 300, second rubber ring 400, sealing ring 500 and sealing assembly 600.

[0039] The injection pipe 100 is used for injecting pulverized coal. Specifically, the injection pipe 100 is provided with several fasteners 102, which are composed of bolts and nuts. The injection pipe 100 has a first mounting groove 104. The top end of the injection pipe 100 is provided with a conveying pipe 101 for conveying pulverized coal. The left side of the injection pipe 100 has a first round hole 103 and a first groove 105 for installing the sealing component 600. Several first round holes 103 are equidistantly distributed. In use, the first mounting groove 104 can hide the fasteners 102 to seal the fasteners 102. The conveying pipe 101 can convey pulverized coal. The first round hole 103 is used to install the fasteners 102, and the first groove 105 is used to install the sealing component 600.

[0040] The blower 200 is used to generate airflow to inject pulverized coal. Specifically, the blower 200 is fixedly connected to the left side of the injection pipe 100 by fasteners 102. The blower 200 has a second mounting groove 202. The right side of the blower 200 has a second round hole 201 and a second groove 203 for installing the sealing component 600. Several second round holes 201 are evenly distributed. In use, the blower 200 and the injection pipe 100 can be fixed by the fasteners 102. The second mounting groove 202 can hide the fasteners 102 to seal them. The second round hole 201 is used to install the fasteners 102, and the second groove 203 is used to install the sealing component 600.

[0041] The first rubber ring 300 is used to seal the fastener 102. Specifically, the first rubber ring 300 is inserted into the left part of the blow pipe 100. In use, the first rubber ring 300 can be moved horizontally to the left until the first rubber ring 300 is engaged with the blow pipe 100 through the slot 301, thus sealing the right part of the bolt.

[0042] The second rubber ring 400 is used to seal the fastener 102. Specifically, the second rubber ring 400 is inserted into the left part of the blow pipe 100. The inner side of both the second rubber ring 400 and the first rubber ring 300 is provided with a groove 301. The second rubber ring 400 and the first rubber ring 300 have the same structure and are symmetrically distributed. In use, the second rubber ring 400 can be moved horizontally to the right until it is engaged with the blower 200 through the groove 301. The fastener 102 can then be sealed by the first rubber ring 300 and the second rubber ring 400, preventing the fastener 102 from contacting water and dust, which would accelerate corrosion and extend its service life.

[0043] The sealing ring 500 is used for sealing. Specifically, the sealing ring 500 is arranged inside the fan 200. During use, the sealing ring 500 can provide a preliminary seal to prevent leakage.

[0044] The sealing assembly 600 is used for sealing. Specifically, the sealing assembly 600 is arranged on the left side of the blow pipe 100. The sealing assembly 600 includes a fixing ring 601 placed on the left side of the blow pipe 100, several springs 603 arranged on the left side of the fixing ring 601, a support ring 604 arranged on the left side of the springs 603, and an O-ring 605 bonded to the left side of the support ring 604. A handle 602 is arranged on the outer side of the fixing ring 601. The four handles 602 are arranged in a circle. In use, the fixing ring 601 can be placed in the first groove 105. Then, the support ring 604 can apply an outward force to the O-ring 605 through the several springs 603, so that the O-ring 605 can be pressed tightly against the blower 200 for sealing. The handles 602 can be gripped tightly. After gripping, the sealing assembly 600 can be moved to install and remove the sealing assembly 600.

[0045] Combination Figures 1-6 In this embodiment of the one-button coal powder injection device, during specific use, the user aligns the right side of the blower 200 with the left side of the injection pipe 100 and connects them. Then, the bolt of the fastener 102 is passed through the second round hole 201 and the first round hole 103 in sequence, and the nut is rotated to fix it. After fixing, the fastener 102 will be in the first mounting groove 104 and the second mounting groove 202. Then, the first rubber ring 300 is moved horizontally until the first rubber ring 300 is engaged with the injection pipe 100 through the slot 301, thus sealing the right side of the bolt. Similarly, the second rubber ring 300 can be moved horizontally. The first rubber ring 400 is inserted into the second rubber ring 400 until the second rubber ring 400 engages with the blower 200 through the slot 301. This seals the fastener 102 with the first rubber ring 300 and the second rubber ring 400, preventing the fastener 102 from coming into contact with water and dust, which would accelerate corrosion and extend its service life. At the same time, when the blower 200 is in use, the sealing ring 500 provides an initial seal, and the spring 603 of the sealing component 600 allows the O-ring 605 to adhere tightly to the blower 200, further sealing it. Thus, the sealing performance is greatly improved by the sealing ring 500 and the sealing component 600, which facilitates the blowing process.
