[Prior Art] The damper is a commonly used device in industrial processes. It can be seen that the damper chamber is mostly a single-pass structure. For example, the damper disclosed in the Republic of China Patent No. M389170 is a typical example, which mainly includes a casing and Blade baffle. The support plate is installed in the casing, and is inserted into the pipe body at both ends to form a state in which the pipe body can rotate. The above-mentioned conventional damper structure has several shortcomings, including: 1. The basic structure is a single passage and cannot be split. If the bypass function is to be provided, it must be assembled and combined with a special pipeline such as a tee, and the additional material cost. And the necessary assembly steps are obviously a burden. ' 2. There are at least 8 degrees c in the structure of the incinerator damper. The internal high temperature often causes the shell raft and the baffle to deform, so the airtight effect cannot be achieved when the baffle is closed. The creator has completed the creation of the case in view of the above shortcomings. [New content] The main purpose of this creation is to provide a high temperature resistant airtight damper. 俾3 M421467 can easily change the direction of the gas flow and is applied to high temperature gas. There are no concerns about leaks. In order to achieve the above object, the damper structure of the present invention comprises a casing, a refractory mud lining and a baffle. The housing defines a first chamber, a second chamber and a communication port therein, wherein the first chamber and the second chamber are respectively located on opposite sides by a communication port. The first chamber extends to an outer surface of the housing to form a damper inlet and a first damper outlet, and the second chamber extends to an outer surface of the housing to form a second damper outlet. The refractory mud lining is attached to the wall surface of the first chamber and the wall surface of the second chamber. The baffle comprises a cooling chamber, wherein the cooling chamber is designed to be cooled by forced circulation of the cooling liquid, and the baffle is pivoted in the first chamber through a rotating shaft, and the communication port or the first damper is selectively covered. Export. The rotating shaft is connected to the baffle and rotatably penetrates the housing. The rotating shaft defines a rotating shaft chamber therein to communicate with the cooling chamber, and the rotating shaft chamber extends to the outer surface of the rotating shaft to form a turn for the coolant to enter and exit. A shaft inlet and a shaft outlet. With the above damper structure design, not only the gas outlet direction can be changed to meet various industrial requirements, but also when the high temperature gas is used, the damper casing or the baffle can be prevented from leaking due to high temperature deformation. In particular, the damper of the creation is simple in structure, convenient in maintenance and repair, and low in cost. Since the rotating shaft is formed with the rotating shaft inlet and the rotating shaft outlet, a coolant can be injected through the rotating shaft inlet to flow through the cooling chamber, and finally exit the rotating shaft outlet to achieve the cooling effect of the rotating shaft and the cooling chamber. The damper structure may further include a hand hole cover, and the first chamber and the second cavity M421467 - the chamber form a hand hole on the outer surface of the casing, and the hand hole cover removably covers the hand hole to facilitate maintenance of the maintenance personnel. The damper structure may further include a fixing base and a driving motor, wherein the fixing seat is fixed on the outer surface of the housing and supports the driving motor, and the driving motor is coupled to the baffle to drive the same. The above casing may be made of heat-resistant steel material SB410, and the baffle may be made of SUS310 or alloy steel. The outer side of the casing is covered with a heat-resistant rock wool insulation, which can reduce the heat loss of the mussels and avoid the burns when the temperature is wrong. The damper structure may further include a rotating shaft coupled to the baffle, the rotating shaft being rotatably disposed through the housing, such that the baffle changes the covering position within the housing by the rotating shaft. A gap between the baffle and the rotating shaft may be provided with a first notch and a second notch. The first notch communicates with the cooling chamber and the front channel, and the second notch communicates with the cooling chamber and the rear channel. The shaft can be respectively disposed outside the two ends of the casing, and each shaft seal is internally provided with a heat-resistant ceramic fiber cotton, which is tightly wound around the gap between the shaft seal and the rotating shaft to reduce the gas generated by the necessary rotation gap inside the damper. The external leakage Φ 情情>. Each shaft seal can be provided with a gas inlet, thereby injecting a gas higher than the pressure in the damper, so that the polluting gas transported inside the duct is completely leak-free, ensuring that untreated gas pollutes the environment. [Embodiment] Referring to Figs. 1 to 4, a perspective view, a perspective cross-sectional view, and a plan sectional view of a damper of a first preferred embodiment are shown. Figure _ shows a rectangular damper, mainly comprising a casing 11 and a baffle 16 assembled in the casing ,. In this example, the M421467 t casing is made of SB410 heat-resistant steel. The housing 11 defines a first chamber 12 and a second chamber 13 therein. The two chambers are disposed in the present embodiment such that the first chamber 12 is below the second chamber 13. The boundary between the first chamber 12 and the second chamber 13 is a communication port 14', that is, the two chambers communicate with each other through the communication port 14. The first chamber 12 extends to the outer surface of the casing 11 to form a damper inlet 121, a first damper outlet 122 and a hand hole 123. The second chamber 13 also extends to the outer surface of the casing 11 to form a second damper outlet 131. And a hand hole 132. The two hand holes 123, 132 are respectively covered with a removable hand hole cover 30, and the main function is to facilitate maintenance. In particular, inside the casing 11, that is, the wall surface of the first chamber 12 and the wall surface of the second chamber 13 are also provided with a gas-fired mud. In this embodiment, the type CA-16 is used for the fire. Refractory mortar. Further, an outer surface of the casing 11 is further covered with an insulating thermal insulation rock wool 21. The support plate 16 is a hollow structure, and a cooling chamber 161' is defined therein. The baffle 16 is pivotally disposed in the first chamber 12. The baffle 16 is selectively covered by the pivoting movement to cover the communication port 14 or the first A damper exit 122. The heat-resistant pottery vibrating material is provided as a heat-resistant sealing sandwich layer 162 at the communication interface 14 and the first damper outlet 122 and the baffle 16 covering contact surface, so that the baffle 16 achieves a high airtight effect when the shunt is closed. In this example, the baffle 16 is pivotally disposed inside the casing n by being rotatably disposed through a rotating shaft 17 of the casing 11. The rotating shaft 17 defines a rotating shaft chamber therein, and the rotating shaft 17 defines a rotating shaft inlet 174 and a rotating shaft outlet 175' respectively on the outer exposed section of the rotating shaft 17 outside the casing 11. The rotating shaft M421467 chamber 171 includes a respective one of the front louver passages ι72 and a rear passage 173, wherein the front passage 172 is in communication with the shaft inlet 174, and the rear passage 173 is in communication with the shaft outlet 175. At the interface between the baffle 16 and the rotating shaft 17, there are two notches 161a, 161b, and the front passage 172 and the cooling chamber 161 communicate with each other through the first notch w1. The rear passage 173 and the cooling chamber ι61 communicate with each other through the second notch 16?. The damper shaft 17 is driven by a drive motor 19. In detail, a fixing seat 18 is fixed to the outer surface of the casing 11, and the driving motor 19 is supported and fixed by the fixing seat 18. The motor 19 is driven and coupled to the rotating shaft 17 to rotate. In particular, the shaft 17 is disposed through a shaft seal 2 贯穿 outside the two ends of the housing π. The inside of each shaft seal 20 is first tightly wound with the heat-resistant ceramic fiber cotton 21 at the front end and the shaft 17 (refer to FIG. 5 at the same time. A partial enlarged view showing one of the shaft seals 20) reduces the leakage of gas inside the damper due to the necessary rotation gap, and opens a gas inlet 22 on the outer surface of the shaft seal 20 to inject a gas higher than the pressure in the damper. The polluting gas transported inside the duct is completely leak-free, ensuring that untreated gas pollutes the environment. It can be seen from the above that the present invention can selectively cover the communication port 14 or the first damper exit port 22 by the arrangement of the damper inner baffle 16, so that the gas in the damper is from the first damper outlet 122 or the second damper outlet 131. Flow out to achieve the purpose of changing the direction of the gas passage. Of course, depending on the actual need, the baffle 16 can also be rotated until the communication port 14 and the first damper outlet 22 are not covered, so that the gas flows out simultaneously from the damper outlets 122, 13 1 . In addition, due to the configuration of the refractory mud lining 15, the temperature of the internal gas during the use of the damper is not easily transmitted to the casing 丨丨, so the entire damper structure is not easily deformed, thereby improving the service life and ensuring industrial safety. Of course, the fire resistant mud will change the type and thickness of the material due to the temperature of use. The baffle 16 is designed as a hollow diversion type, so that the coolant can be injected to enhance the cooling, avoiding the deformation of the main body of the plate, and also has the effect of improving the service life of the damper, as shown by the arrow in Fig. 2, the flow direction of the coolant. The use of the heat-resistant ceramic fiber cotton as the heat-resistant sealing sandwich layer 162 allows the baffle 16 to achieve a high airtight effect due to the soft and hard surface of the baffle 16 when the shunt is closed. Even if the baffle 16 is slightly deformed by high temperature, it does not affect the airtightness. The present invention also allows the cooling fluid to be injected into the rotating shaft 17 and into the cooling chamber 161 of the baffle 16 by designing the rotating shaft for interlocking the baffle to have a hollow state with an inlet and an outlet, thereby also cooling the rotating shaft and avoiding turning. The shaft deformation effect also has the effect of improving the service life of the damper. In summary, this creation develops a special high-temperature-resistant airtight damper structure, which also has the function of channel switching, and has the characteristics of novelty and progress. In this creation, the driving motor power can be hydraulic, electric, pneumatic, and the like. The transmission part can also be a linear rotation or a connecting rod to make the baffle rotate 90 degrees. The above-described embodiments are merely examples for convenience of description, and the scope of the claims is intended to be based on the scope of the patent application, and is not limited to the above embodiments.
