[0035] like Figure 1 to Figure 6As shown, this embodiment proposes a furnace top material blocking spherical structure, including: a containing box 1 having a symmetrically arranged feed port 101 and a discharge port 102, and a containing cavity 103 located between the feed port 101 and the discharge port 102, and the discharge port 102 is used to connect to the furnace body; a first shell 2 is swingably set in the containing cavity 103, and after the first shell 2 swings, it blocks or cancels blocking the discharge port 102.

[0036] In this embodiment, the container box 1 is designed as a symmetrical structure, with a feed port 101 and a discharge port 102, respectively. The feed port 101 is used to receive raw materials transported from the outside, and the discharge port 102 is directly connected to the inside of the furnace body, and is used to put materials into the furnace. The container box 1 has a spherical receiving cavity 103 inside. After the material enters from the feed port 101, it is temporarily stored in the receiving cavity 103, and finally sent to the furnace body through the discharge port 102; the first shell 2 can swing around a certain pivot or hinge to achieve the blocking or cancellation of the discharge port 102. When the first shell 2 is swung to a specific position, the discharge port 102 is completely or partially blocked, restricting the material from entering the furnace body; conversely, when the first shell 2 is swung open, the discharge port 102 is unobstructed, and the material can smoothly enter the furnace. The operator can control the swing angle of the first shell 2 to increase or decrease the size of the discharge port 102 to control the speed and quantity of materials entering the furnace body; when the first shell 2 is worn, the operator can directly replace the first shell 2, which saves costs compared to replacing the material flow regulating and blocking valve.

[0037] Optionally, it also includes: the second shell 3 is swingably disposed in the accommodating cavity 103 and is hingedly connected to the first shell 2 , and after the first shell 2 and the second shell 3 swing relatively, the discharge port 102 is blocked or unblocked.

[0038] In this embodiment, the second shell 3 is swingably set in the accommodating cavity 103, and is connected to the first shell 2 by a hinge, so that the second shell 3 and the first shell 2 can swing relatively independently. When the first shell 2 swings clockwise and the second shell 3 swings counterclockwise, the first shell 2 and the second shell 3 move away from each other, canceling the blocking of the discharge port 102, and increasing the flow rate of the material at the discharge port 102; when the first shell 2 swings counterclockwise and the second shell 3 swings clockwise, the first shell 2 and the second shell 3 move closer to each other, blocking the discharge port 102, and reducing the flow rate of the material at the discharge port 102. Through the coordinated swinging between the first shell 2 and the second shell 3, a more precise opening and closing control of the discharge port 102 is achieved to meet different charging requirements. At the same time, when the first shell 2 or the second shell 3 is used for a long time and wears out, the operator can directly replace it, which saves costs compared to replacing the material flow regulating and blocking valve.

[0039] Optionally, both the first shell 2 and the second shell 3 have a material passage opening 203 , and after the first shell 2 and the second shell 3 swing, a material passage space 4 is formed between the two material passage openings 203 , and the material passage space 4 is connected to the discharge opening 102 .

[0040] In this embodiment, both the first shell 2 and the second shell 3 are designed with a material passage 203. When the first shell 2 is docked with the second shell 3, the two material passages 203 are aligned with each other to form a continuous material passage space 4, which is directly connected to the discharge port 102 to ensure that the material can pass through the material passage space 4 and enter the furnace body. When the first shell 2 swings counterclockwise and the second shell 3 swings clockwise, that is, when the first shell 2 and the second shell 3 overlap, the two material passages 203 approach each other, so that the material passage space 4 formed between the two material passages 203 is reduced, thereby limiting the flow rate of the material entering the furnace body.

[0041] Optionally, the first shell 2 has a baffle 201 and a connecting seat 202 , the baffle 201 is disposed on the connecting seat 202 , the material passage 203 is located on the baffle 201 , and the connecting seat 202 is hingedly connected to the containing box 1 .

[0042] The material passage 203 is located on the baffle 201; the baffle 201 is in a spherical shell shape; the baffle 201 is made of wear-resistant material and can adapt to high temperature environments; the connecting seat 202 is connected to the baffle 201 by bolts; the operator can replace the baffle 201 with a new one according to the wear of the baffle 201. The baffle 201 and the connecting seat 202 are detachably connected, which is convenient for the operator to replace and repair compared to the integral molding of the baffle 201 and the connecting seat 202.

[0043] Optionally, the first shell 2 and the second shell 3 have the same structure, and the connecting seat 202 in the first shell 2 is hingedly connected to the connecting seat 202 in the second shell 3 .

[0044] In this embodiment, the first shell 2 and the second shell 3 have the same structure, that is, the first shell 2 and the second shell 3 both include a baffle 201, a connecting seat 202, and a material passage 203 provided on the baffle 201. In addition, the connecting seat 202 in the first shell 2 and the connecting seat 202 in the second shell 3 are connected to each other by a hinged manner to form a linked double shell system. The design of the same structure of the first shell 2 and the second shell 3 simplifies the manufacturing process, is conducive to reducing costs, and at the same time ensures the consistency and coordination of the two shells during the swinging process.

[0045] Optionally, it further includes: a first swing rod 5 is swingably arranged at one side of the accommodating box 1; and two ends of the first transmission connecting rod 6 are respectively hingedly connected to the first swing rod 5 and the connecting seat 202 of the first shell 2.

[0046] Optionally, it also includes: the second swing rod 7 has a swing direction opposite to that of the first swing rod 5, the second swing rod 7 is swingably arranged on the other side of the accommodating box 1, and is symmetrically arranged with the first swing rod 5; the two ends of the second transmission connecting rod 8 are respectively hingedly connected to the second swing rod 7 and the connecting seat 202 of the second shell 3.

[0047] Optionally, it further includes: a driving member 9 is arranged on the containing box 1, and the driving member 9 is used to drive the first swinging rod 5 and the second swinging rod 7 to swing.

[0048] In this embodiment, the synchronous swing control form of the first shell 2 and the second shell 3 is as follows: the operator can operate the driving member 9 to make the first swing rod 5 and the second swing rod 7 swing respectively. It should be noted that the swinging directions of the first swing rod 5 and the second swing rod 7 are opposite. Then the first transmission connecting rod 6 and the second transmission connecting rod 8 respectively transmit the swinging motion of the first swing rod 5 and the second swing rod 7 to the first shell 2 and the second shell 3, so that the first shell 2 and the second shell 3 swing relative to each other, so that the material blocking spherical structure can be driven by the driving member 9 to quickly and accurately adjust the opening and shape of the material passing space 4 to adapt to different working conditions and operation requirements, thereby improving the automation level and control accuracy of the furnace top loading system.

[0049] In this embodiment, the first swing arm 5 and the second swing arm 7 are usually made of high-strength material, have a certain rigidity and toughness, and can withstand stress and impact during the swinging process; the design of the first transmission link 6 and the second transmission link 8 should ensure the rationality of the length, rigidity and hinge point position to ensure the smoothness, accuracy and efficiency of the first shell 2 and the second shell 3 when swinging; the first swing arm 5 and the second swing arm 7 are symmetrically arranged so that the swinging of the first swing arm 5 and the second swing arm 7 can be balanced with each other, reducing the eccentric torque on the containing box 1 and improving the stability of the entire structure; the driving member 9 can be a power source such as an electric motor, a hydraulic cylinder, a pneumatic cylinder, etc., and the power is transmitted to the first swing arm 5 and the second swing arm 7 respectively through a transmission mechanism such as: gears, racks, chains, belts.
