Double-chamber kiln is mainly suitable for the steel industry using coke oven gas and calcium carbide, and the chemical industry using calcium carbide furnace exhaust gas and other technologies to produce high-quality lime. The finished lime powder is discharged through the discharge port at the bottom of the kiln and enters the cooling equipment. In the cooling equipment, the lime powder is cooled to a suitable temperature and then sent to the storage area via conveying equipment. Pneumatic conveying equipment is usually used to transport the lime powder.

[0003] Pneumatic conveying equipment is usually composed of air source equipment, receiving device, conveying pipeline, separator, air lock, dust collector and control system to realize the conveying of lime powder.

DETAILED DESCRIPTION

[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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0036] Example 1: Please refer to Figure 1 - Fig.10 The present invention provides a technical solution: a double-opening kiln lime powder pneumatic conveying device, comprising a main body mechanism 1, the main body mechanism 1 comprises a fan 11, a first pipeline 12 and a second pipeline 13, the output end of the fan 11 is fixedly connected with the first pipeline 12, the first pipeline 12 and the second pipeline 13 are fixedly connected through a flange 14, a first half box 15 is fixedly sleeved on the surface of the first pipeline 12, a second half box 16 is sleeved on the surface of the second pipeline 13, the first half box 15 and the second half box 16 are fixedly connected by bolts, the first half box 15 and the second half box 16 are respectively fixed in advance on the surfaces of the first pipeline 12 and the second pipeline 13 by welding, and then the flange 14 is installed, and the surfaces of the first pipeline 12 and the second pipeline 13 are provided with a gas leakage detection mechanism 2;

[0037] The gas leakage detection mechanism 2 comprises a whistle unit 21, which is arranged in the inner cavity of the second half box 16, and is used for converting the driving force of the leaked gas into a whistle sound.

[0038] As a further limitation of the air leakage detection mechanism 2 of the present invention, the whistle unit 21 includes two sliding cylinders 2101, both of which are slidably connected to the inner wall of the second half box 16, and the two sliding cylinders 2101 are arranged opposite to each other up and down, one end of the sliding cylinder 2101 is fixedly connected to the first pressure plate 2102, one side of the first pressure plate 2102 is in contact with the surface of the flange 14, the inner cavity of the sliding cylinder 2101 is slidably connected to the piston 2103, one end of the sliding cylinder 2101 passes through the outside of the second half box 16 and is fixedly connected to the whistle cylinder 2104, and the lower surface of the whistle cylinder 2104 is provided with an air outlet 2105, and the whistle cylinder 2104 has an air outlet hole 2105. A wedge block 2106 is fixedly connected at the entrance, and one end of the whistle tube 2104 is sealed; by providing the whistle unit 21, the impact of the gas leaking from the gap between the two flanges 14 can push the piston 2103 to slide in the inner cavity of the sliding cylinder 2101, and the movement of the piston 2103 pushes the air in the inner cavity of the sliding cylinder 2101 into the inner cavity of the whistle tube 2104, forming a whistle sound, thereby attracting the attention of maintenance personnel, providing an auditory warning for the leakage between the first pipeline 12 and the second pipeline 13, and facilitating maintenance personnel to detect gas leakage in time, thereby avoiding continuous loss and waste of air force and improving the transportation efficiency of lime powder.

[0039] Two threaded rods 2107 are threadedly connected to the inner wall of the second half box 16, and one end of the two threaded rods 2107 is rotatably connected to a connecting plate 2108 through a bearing. One side of the connecting plate 2108 is fixedly connected to one side of the first pressure plate 2102, and the other end of the threaded rod 2107 passes through the outer side of the second half box 16 and is fixedly connected to a knob 2109. By setting the threaded rod 2107, the connecting plate 2108 and the knob 2109, after the user completes the installation of the first half box 15 and the second half box 16, the user rotates the knob 2109, and the rotation of the knob 2109 drives the threaded rod 2107 to rotate. The threaded connection relationship between the threaded rod 2107 and the second half box 16 causes the threaded rod 2107 itself to move, driving the connecting plate 2108 and the first pressure plate 2102 to approach the surface of the flange 14 until the first pressure plate 2102 is in close contact with the surface of the flange 14, thereby realizing the positioning of the first pressure plate 2102 on the surface of the flange 14.

[0040] The specific implementation of this embodiment is as follows: before the first pipe 12 and the second pipe 13 are connected, the first half box 15 is fixed on the surface of the first pipe 12 by welding, and then the flange 14 at the end of the first pipe 12 is welded so that the flange 14 and the first half box 15 are kept within the required distance. The second half box 16 is fixed at a suitable position on the surface of the second pipe 13 in the same way, and then the flange 14 at the end of the second pipe 13 is installed, and the two flanges 14 are fixed by bolts to ensure the sealing between the two flanges 14. At this time, the first half box 15 and the second half box 16 are in a tightly fitted state, and the two are fixed by bolts. Then, by turning the knob 2109, the rotation of the knob 2109 drives the threaded rod 2107 to rotate, and the threaded connection relationship between the threaded rod 2107 and the second half box 16 causes the threaded rod 2107 to move itself, driving the connecting plate 2108 and the first pressing plate 2102 to approach the surface of the flange 14 until the first pressing plate 2102 is in close contact with the surface of the flange 14. When the gas leaks from the gap of the flange 14, a closed cavity is formed at the periphery of the gap between the two flanges 14, so as to timely intercept the gas leaking from the gap of the flange 14. If the gas leaks from the gap of the flange 14, the leaked gas enters the closed cavity. As the gas continues to increase, the air pressure in the cavity gradually increases, so that the gas enters the inner cavity of the sliding cylinder 2101, and pushes the piston 2103 to move in the inner cavity of the sliding cylinder 2101. The movement of the piston 2103 pushes the air in the inner cavity of the sliding cylinder 2101, so that the air enters the whistle tube 2104. The wedge block 2106 and the air outlet 2105 in the whistle tube 2104 cooperate to guide and cut the air entering the whistle tube 2104, and resonance is generated in the cavity of the whistle tube 2104, thereby emitting a whistle sound, thereby attracting the attention of the maintenance personnel, providing an auditory warning for the leakage between the first pipeline 12 and the second pipeline 13, and facilitating the maintenance personnel to find the gas leakage in time, thereby avoiding the continuous loss and waste of air force and improving the transportation efficiency of lime powder.

One end of the colored cloth belt 2209 is fixedly connected to a connecting rope 2211, and one end of the connecting rope 2211 is fixedly connected to a counterweight block 2212. By setting a visual warning unit 22, when gas leaks, the piston 2103 is pushed to move. During the movement of the piston 2103, the first magnet block 2201 and the second magnet block 2203 are used in cooperation to convert the moving force of the piston 2103 into an unwinding force of the colored cloth belt 2209, so that the colored cloth belt 2209 is scattered to a certain length, and the gas leakage is converted into a visual display, which attracts the attention of maintenance personnel and facilitates maintenance personnel to promptly discover the gas leakage, thereby avoiding continuous loss and waste of gas power and improving the transportation efficiency of lime powder.

[0043] Two guide blocks 2213 are fixedly connected to the surface of one of the protrusions 2202, and the two protrusions 2202 are arranged opposite to each other in the upper and lower directions. Both ends of the protrusion 2202 are fixedly connected to the limiting plates 2214, and the opposite sides of the two limiting plates 2214 are respectively fixedly connected to the two ends of the two guide blocks 2213, and the second magnet block 2203 is slidably connected to the surface of the guide block 2213; by setting the guide block 2213 and the limiting plate 2214, the moving direction of the second magnet block 2203 can be guided, thereby increasing the stability of the second magnet block 2203 during movement, and the moving distance of the second magnet block 2203 can be limited by the limiting plate 2214.

[0044] A movable hole 2215 is provided at the top of the support plate 2206, and a guide cylinder 2216 is fixedly connected to the top of the support plate 2206. The guide cylinder 2216 and the movable hole 2215 are communicated with each other, and the connecting rope 2211 is slidably connected to the inner cavity of the guide cylinder 2216, and the counterweight block 2212 is slidably connected to the inner cavity of the movable hole 2215; by setting the movable hole 2215, space is provided for the counterweight block 2212 to be stored in the inner cavity of the support plate 2206, and the movement of the connecting rope 2211 is guided and supported by the guide cylinder 2216, and the top surface of the guide cylinder 2216 is flush with the top surface of the lower round block 2208, thereby ensuring the stability of the colored cloth belt 2209 during unwinding and rewinding, and ensuring that the colored cloth belt 2209 will be rewound between the two round blocks 2208 during rewinding.

By setting the shielding shell 2217, the colored cloth tape 2209 can be shielded and protected, and the service life of the colored cloth tape 2209 can be extended. The setting of the first spring 2218 can help the piston 2103 and the first magnet block 2201 to reset through the reaction force of the first spring 2218.

[0046] The specific implementation method of this embodiment is as follows: in order to prevent the maintenance personnel from failing to receive the whistle sound emitted by the whistle tube 2104 in time, during the movement of the piston 2103, the first magnet block 2201 is driven to move, the movement of the first magnet block 2201 drives the second magnet block 2203 to move synchronously, the movement of the second magnet block 2203 drives the extension block 2204 to move, the movement of the extension block 2204 drives the tooth plate 2205 to move, the movement of the tooth plate 2205 causes the gear 2210 to rotate, through the cooperation of the bearing and the support plate 2206, the rotation of the gear 2210 drives the winding rod 2207 to rotate, and in the initial state, the colored cloth belt 2209 is wound on the winding rod 2207 and is located between the two round blocks 2208 When the winding rod 2207 rotates, the colored cloth belt 2209 is unwound. At this time, the counterweight block 2212 stored in the movable hole 2215 begins to fall, driving the connecting rope 2211 to move downward. The connecting rope 2211 is guided by the guide cylinder 2216. The movement of the connecting rope 2211 drives the colored cloth belt 2209 to pass through the guide cylinder 2216 and the movable hole 2215, and gradually moves downward, so that the colored cloth belt 2209 is exposed to the air in a sufficient length. Through the display of the colored cloth belt 2209, the gas leakage situation is more intuitively displayed, which attracts the attention of the maintenance personnel and is convenient for the maintenance personnel to detect the gas leakage in time, thereby avoiding the continuous loss and waste of air force and improving the transportation efficiency of lime powder.

[0047] Example 3: Please refer to Figure 1 - Fig.10 The present invention provides a technical solution: a double-opening kiln lime powder pneumatic conveying device. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The leakage detection mechanism 2 also includes a leak plugging unit 23. The leak plugging unit 23 is used in conjunction with the whistle unit 21 and the visual warning unit 22. The leak plugging unit 23 is used to temporarily plug the leak.

[0048] As a further limitation of the air leakage detection mechanism 2 of the present invention, the leak blocking unit 23 includes a positioning groove 2301, which is opened on the inner wall of the first half box 15, and the number of the positioning grooves 2301 is several. The inner wall of each positioning groove 2301 is fixedly connected with a second spring 2302, and one end of the plurality of second springs 2302 is commonly fixedly connected with a snap ring 2303, and the inner side of the snap ring 2303 is fixedly connected with a sealing ring 2304, and the sealing ring 2304 is used to block the gap between the two flanges 14. The other ends of the two pistons 2103 are fixedly connected with a pull rope 2305, and one end of the pull rope 2305 is fixedly connected to one side of the retaining ring 2303; by setting up the leak-proof unit 23, the driving force of the leaking gas on the piston 2103 is converted into a blocking force of the retaining ring 2303 and the sealing ring 2304 on the gap between the two flanges 14, thereby achieving temporary plugging of the gap, avoiding continuous leakage of gas, gaining sufficient time for maintenance personnel, avoiding continuous loss and waste of gas, and improving the transportation efficiency of lime powder.

[0049] A retaining ring 2306 is fixedly connected to the inner wall of the first half box 15, and a clamping ring 2307 is fixedly connected to one side of the first pressure plate 2102. A clamping groove 2308 is opened on one side of the retaining ring 2306. The surface of the clamping ring 2307 is in close contact with the inner cavity of the clamping groove 2308. The retaining ring 2306 and the clamping ring 2307 are embedded in a closed cavity for intercepting leaked gas in the first time. By setting the retaining ring 2306, the clamping ring 2307 and the clamping groove 2308, during installation, after one side of the first pressure plate 2102 is tightly fitted with the surface of the flange 14, the clamping ring 2307 is simultaneously embedded in the inner cavity of the clamping groove 2308, thereby increasing the tightness of the embedding between the first pressure plate 2102 and the retaining ring 2306.

[0051] The specific implementation of this embodiment is as follows: when the two pistons 2103 have moved most of the distance, the continued movement of the two pistons 2103 generates a pulling force on the two pull ropes 2305. In the initial state, the lengths of the two pull ropes 2305 are in a redundant state, providing sufficient time for the triggering of the whistle unit 21 and the visual warning unit 22. The movement of the two pull ropes 2305 causes the snap ring 2303 to move. In the initial state, the snap ring 2303 is tightly attached to the inner wall of the first half box 15 through a plurality of second springs 2302, and the second springs 2302 are received by the positioning grooves 2301. On the inner wall of the first half box 15, the movement of the retaining ring 2303 drives the sealing ring 2304 to move. The contact surface between the sealing ring 2304 and the flange 14 is set at an inclined surface, until the piston 2103 moves to the extreme position, so that the sealing ring 2304 is pulled to fit tightly with the gap of the flange 14, and at this time, one side of the retaining ring 2303 contacts the first pressure plate 2102, thereby achieving temporary plugging of the leakage, avoiding continuous leakage of air, and gaining enough time for maintenance personnel to perform maintenance, avoiding continuous loss and waste of air, and improving the transportation efficiency of lime powder.
