Description

Technical Field

[0001] The invention relates to the technical field of steel slag processing equipment, in particular to a vertical steel slag hot stuffy reaction tank. Background Art

[0002] At present, the main steel slag treatment processes at home and abroad include hot pouring method, water quenching method, granulation method and hot stuffing method. Since the hot stuffing method has the advantages of good stability of the treated steel slag, high pulverization rate, and sufficient slag and iron separation, it can achieve zero discharge of steel slag, so the hot stuffing method has a wide range of applications. As one of the hot stuffing process treatment equipment, the hot stuffing reactor plays a vital role.

[0003] The Chinese invention patent application No. 202010789290.8 discloses a large-diameter vertical steel slag pressurized hot tank, which can realize the frequent opening and closing function of the hot hot tank cover, and can realize the pressure-maintaining function when combined with a sealing device. However, when the hot hot tank is in use, it drives the tank cover to rotate around its central axis through the tank cover locking device so that the teeth of the tank cover flange and the teeth of the tank body flange change from overlap to separation or separation to overlap, so as to realize the opening and closing sealing of the tank cover. Since the tank cover itself weighs several tons, the tank cover locking device is required to have a sufficiently high driving force. At the same time, when the hot hot tank cover is closed and pressure maintained, in order to ensure the sealing, the tank cover locking device is required to provide a continuous driving force to ensure the locking state of the tank cover and the tank body. Therefore, the driving mechanism of the tank cover locking device includes two or three sets of oil cylinders, which leads to a high cost of the hot hot tank. At the same time, complex structures are required to cooperate and link between multiple oil cylinders to provide a higher driving force. Therefore, it not only occupies a large space, but also it is difficult to ensure the stability of the driving force, and there is a risk of poor sealing. Summary of the invention

[0004] In view of the problem that the existing pressurized hot stuffy tanks need to be used in conjunction with a sufficiently high driving force, resulting in high cost, complex structure, large space occupation and risk of poor sealing, the present invention provides a vertical steel slag hot stuffy reaction tank, the sealing of the tank body and the tank cover requires a small driving force, low cost, and good stability, thereby improving the sealing reliability and reducing the risk of poor sealing.

[0005] The technical solution is as follows: a vertical steel slag hot stuffy reaction tank, comprising a tank body and a tank cover, wherein the port position of the tank cover is provided with external teeth, and the characteristics are: a tank cover opening and closing mechanism connected to the tank cover is provided on the tank body, and the tank cover is driven to be opened or closed by the tank cover opening and closing mechanism;

[0006] A flange ring is sleeved at the mouth position of the tank body in a rotatable connection. An internal tooth that mates with the external teeth of the tank cover is provided on the inner wall of the flange ring. An unlocking mechanism that is in power cooperation with the flange ring is further provided outside the tank body. The flange ring is driven to rotate by the unlocking mechanism, so that the internal teeth thereon coincide or are arranged alternately with the external teeth of the tank cover.

[0007] It is further characterized in that: the unlocking mechanism includes a locking cylinder installed outside the tank body. A gear is sleeved outside the piston rod of the locking cylinder. A rack that is meshed and connected with the gear is installed on the outer wall of the flange ring;

[0008] An upper flange interface is connected to the mouth of the tank cover. The external teeth are arranged along the lower outer edge of the upper flange interface. A lower flange interface that mates with the upper flange interface is provided at the mouth of the tank body. The cross section of the flange ring is in a "U" shape. The internal teeth are arranged along the inner wall of the upper end port of the flange ring. The lower edge of the flange ring is in a rotatable connection with the flange of the lower flange interface. The internal teeth on the upper edge of the flange ring enclose the external teeth of the tank cover inside and are arranged in an overlapping or alternating manner in cooperation with each other;

[0009] A sealing ring that protrudes outwards is installed circumferentially along the lower flange interface;

[0010] A roller that contacts the lower end surface of the flange ring is further installed outside the tank body;

[0011] A roller that contacts the outer wall of the tank body is installed on the lower end surface of the flange ring;

[0012] The opening and closing mechanism of the tank cover includes an oil cylinder installed outside the tank body. The piston rod of the oil cylinder is hinged to the outer side surface of one end of a rotating arm. The inner side surface of one end of the rotating arm is connected to the outer wall of the tank body through a hinge seat. The other end of the rotating arm is connected to the tank cover;

[0013] A limiting mechanism is further provided on the tank body. The limiting mechanism is connected to the flange ring to prevent rotation. The limiting mechanism includes a limiting cylinder connected to the tank body through a mounting plate. The cylinder body of the limiting cylinder is connected to the mounting plate through a hinge seat. The piston rod of the limiting cylinder is connected with a limiting pin through a hinge seat. A matching limiting sleeve is provided on the mounting plate in the moving direction of the limiting pin. A clamping sleeve that mates with the limiting pin is provided on the outer wall of the flange ring.

[0014] After adopting the above structure, since an opening and closing mechanism of the tank cover that is connected to the tank cover is provided on the tank body, the tank cover is driven to be opened or closed by the opening and closing mechanism of the tank cover, and the operation is convenient;

[0015] At the same time, since a rotatably connected flange ring is provided on the tank body, after the tank cover and the tank body are closed, the flange ring is driven to rotate by the tank cover locking mechanism, so that the internal teeth thereon coincide with or are arranged alternately with the external teeth of the tank cover, thereby achieving a sealing and locking function. Since the present invention adopts a driving mechanism to drive the movably connected flange ring to achieve the sealing purpose, not only the required driving force is small and the cost is low, but also the stability can be ensured, the sealing reliability is improved, and the risk of poor sealing is reduced.

The inner wall of the flange ring 3 is provided with an internal tooth 5 that matches the external tooth 4 of the tank cover 2. The outside of the tank body 1 is also provided with a tank cover locking mechanism that is dynamically matched with the flange ring 3. The flange ring 3 is driven to rotate by the tank cover locking mechanism, so that the internal tooth 5 thereon coincides with the external tooth of the tank cover 2 or is arranged in an interlaced manner, so that the tank body 1 and the tank cover 2 are locked and sealed or unlocked.

[0025] Preferably, the lid locking mechanism includes a locking cylinder 6 installed outside the tank body 1. The cylinder block of the locking cylinder 6 is connected to the outer wall of the tank body 1 through a mounting seat. A gear 7 is sleeved outside the piston rod of the locking cylinder 6. An arc-shaped rack 8 meshing with the gear 7 is installed on the outer wall of the flange ring 3. During operation, the locking cylinder 6 drives the flange ring 3 to rotate relative to the tank body 1 through the meshing gear 7 and rack 8, so that the flange ring 3 locks or unlocks the tank lid 2.

[0026] Preferably, an upper flange interface 9 is connected to the mouth of the tank lid 2. The external teeth 4 are arranged along the lower outer edge of the upper flange interface 9. The external teeth 4 can be integrally formed with the upper flange interface 9. A lower flange interface 10 matching the upper flange interface 9 is provided at the mouth of the tank body 1. The cross-section of the flange ring 3 is in a "U" shape. The internal teeth 5 are arranged along the inner wall of the upper end port of the flange ring 3. The lower edge of the flange ring 3 is rotationally connected to the flange of the lower flange interface 10 in a matching manner. The internal teeth 5 on the upper edge of the flange ring 3 enclose the external teeth 4 of the tank lid 2 inside and cooperate with each other, and are arranged in an overlapping or staggered manner.

[0027] Preferably, a sealing ring 11 protruding outwards is embedded along the circumference of the lower flange interface 10. Through the setting of the sealing ring 11, the tank lid 2 and the tank body 1 are sealed and pressurized.

[0028] Preferably, a roller 12 contacting the lower end surface of the flange 3 ring is also installed outside the tank body 1. The roller 12 can include two, symmetrically arranged relative to the tank body 1. Through the setting of the roller 12, it not only supports the flange ring 3, but also provides an auxiliary force when the flange ring 3 rotates, so that it can rotate flexibly and prevent the flange ring 3 from getting stuck abnormally.

[0029] Preferably, a roller 13 contacting the outer wall of the tank body 2 is installed on the lower end surface of the flange ring 3. The setting of the roller 13 also ensures the flexibility of the rotation of the flange ring 3.

[0030] Preferably, the lid opening and closing mechanism includes an oil cylinder 14 installed outside the tank body 1. The cylinder block of the oil cylinder 14 is rotatably connected to the outer wall of the tank body 1. The piston rod of the oil cylinder 14 is hinged to the outer side surface of one end of the rotating arm 15. The inner side surface of one end of the rotating arm 15 is connected to the outer wall of the tank body 1 through a hinge seat. The other end of the rotating arm 15 is fixedly connected along the radius of the tank lid 2. During operation, the oil cylinder 14 drives the tank lid 2 to open or close.

[0031] Preferably, the tank body 1 is also provided with a limiting mechanism, which includes two and symmetrically arranged. By adjusting the limiting mechanism to connect with the flange ring 3 and prevent it from rotating, the stability of the flange ring 3 in the locked state is ensured. Specifically, the limiting mechanism includes a limiting cylinder 16 connected to the tank body 1 through a mounting plate, the cylinder body of the limiting cylinder 16 is connected to the mounting plate through a hinge seat, the piston rod of the limiting cylinder 16 is connected to the limiting pin 17 through a hinge seat, a matching limiting sleeve 18 is provided on the mounting plate corresponding to the moving direction of the limiting pin 17, and the outer wall of the flange ring 3 is provided with a clamping sleeve 19 matching the limiting pin 17. The limiting cylinder 16 drives the limiting pin 17 to extend into the limiting sleeve 18 and clamp and connect with the clamping sleeve 19 on the flange ring 3, thereby limiting the flange ring 3 to prevent the flange ring 3 from rotating, and cooperating with the tank cover locking mechanism to lock the flange ring 3, ensuring that the tank body 1 and the tank cover 2 are sealed and locked after closing.

[0032] The working principle of the present invention is as follows:

[0033] The tank cover 2 and the tank body 1 are driven to open or close by the tank cover opening and closing mechanism, which facilitates the operation of the hot stuffy reaction tank. After the tank cover 2 is closed, the flange ring 3 is driven to rotate by the tank cover locking mechanism so that the inner teeth 5 thereon coincide with the outer teeth of the tank cover 2 or are arranged in a staggered manner. When staggered, the tank cover 1 and the flange ring 3 are in a locked and sealed state, which not only reduces the driving force required for adjustment and reduces the cost of use, but also has a stable and reliable sealing structure, which also ensures the safety of the hot stuffy reaction tank in use; and then the flange ring 3 is connected with the limiting mechanism to further ensure the locking of the tank cover 1 and the flange ring 3, and ensure the stability of the locking of the flange ring 3 and the tank cover 2.
