DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-5 A high-efficiency delayed coke calcining furnace comprises a body 1, an opening and closing door 2 is provided on the outer wall of the body 1, a furnace pipe 8 is penetrated through the outer wall of the body 1, a feed box 3 is fixedly installed at the end of the furnace pipe 8, a motor 4 is fixedly installed on the outer wall of the feed box 3, a collecting hopper 7 is fixedly installed on the top of the feed box 3, a furnace pipe 8 is opened on the top of the collecting hopper 7, a feeding pipe 9 is penetrated on the top of the collecting hopper 7, a sealing shell 6 is rotatably connected to the inner wall of the furnace pipe 8, a fixed platform 15 is provided on the top of the sealing shell 6, a motor 2 5 is fixedly installed on the top of the fixed platform 15, a gear 14 is fixedly sleeved on the output shaft of the motor 2 5, a transmission belt 16 is rollingly connected to the middle part of the gear 14, a rotating wheel 13 is rollingly connected to the end of the transmission belt 16, a rotating rod 10 is fixedly installed on the bottom of the gear 14, a connecting rod 12 is fixedly installed on the outer wall of the rotating rod 10, and a scraper 11 is fixedly installed on the end of the connecting rod 12.

[0022] In the above structure, by setting the motor 2 5, fixed platform 15, gear 14, transmission belt 16, rotating wheel 13, feeding tube 9, and sealing shell 6 structure, during the operation of the calcining furnace, the user can drive the gear 14 to rotate through the motor 2 5, so that the protrusion on the rotating wheel 13 engages with the tooth groove, thereby rotating the sealing shell 6, allowing the position of the circular hole 1 to coincide with the feeding tube 9, so that the user can pour the material into the collecting hopper 7. During the operation of the equipment, the circular hole 1 is misaligned with the feeding tube 9, so that the motor 1 4 and the threaded feeding rod are used to achieve the effect of automatic feeding, which not only improves the sealing of the calcining furnace, but also improves the automation of the calcining furnace.

[0023] In a preferred embodiment: circular hole one and circular hole two are provided at the top of the sealing shell 6, the top of the inner wall of the sealing shell 6 is rotatably connected to the top of the feeding tube 9, and the diameter of circular hole one is adapted to the diameter of the feeding tube 9, a limiting groove is provided on the inner wall of circular hole two, and the limiting groove and the inner wall of circular hole two are both rotatably connected to the outer wall of the fixed platform 15.

[0024] In the above structure, by setting the circular hole one and circular hole two structures, the circular hole one is overlapped with the feeding tube 9, which is convenient for the user to perform the feeding operation. After the feeding operation, the user can rotate the sealing shell 6 through the activity space provided by the circular hole two, so as to ensure that the contact time of the feeding tube 9 with the outside world is reduced to a minimum, thereby reducing the loss of heat energy and achieving the effect of sealing the calcining furnace. At the same time, the circular hole two and the limit groove can limit the fixed table 15, thereby ensuring the stability of the motor two 5 during the operation.

[0025] In a preferred embodiment, the inner wall of the sealing shell 6 is provided with a tooth groove, the outer wall of the rotating wheel 13 is fixedly equipped with a protrusion, and the outer wall of the protrusion is meshed with the inner wall of the tooth groove.

[0026] In the above structure, by setting the tooth groove and protrusion structure, the motor 2 5 can not only drive the rotating rod 10 to rotate during operation, but also cooperate with the transmission effect of the transmission belt 16 to enable the rotating wheel 13 to drive the sealing shell 6 to rotate, so that the circular hole 1 can be misaligned with the feeding pipe 9, thereby improving the energy utilization rate of the calcining furnace.

[0027] In a preferred embodiment, the outer wall of the scraper 11 is rotatably connected to the inner wall of the collecting hopper 7 , the number of the scraper 11 is three, and the three scraper 11 are evenly distributed along the inner wall of the collecting hopper 7 .

[0028] In the above structure, through the scraper 11 and the collecting hopper 7 structure, the collecting hopper 7 can store the input material, so that the threaded feed rod can transport the material to the main body 1 for calcination, and the scraper 11 can scrape the inner wall of the collecting hopper 7 when the motor 2 5 is operating, thereby ensuring that the material cannot stagnate in the collecting hopper 7, thereby improving the material transportation effect of the calcining furnace.

[0029] In a preferred embodiment: the output shaft of the motor 4 is fixedly sleeved with a threaded feed rod, the inner wall of the main body 1 is fixedly equipped with a furnace, and the furnace is made of alumina ceramic fiber, the inner wall of the main body 1 is also fixedly equipped with a heating element, and the heating element is made of high-temperature straight high-quality silicon carbon in the shape of a rod.

[0030] In the above structure, through the setting of the furnace and heating element structure, the overall heating zone length of the main body 1 is 1500 mm, and the specification of the furnace tube 8 is about Φ60×2300 mm, so that the calcining furnace can be divided into three areas for heating operations in different temperature ranges to ensure the calcination effect of the material. The alumina ceramic fiber has extremely high thermal conductivity and heating shrinkage rate, which reduces the loss of heat energy during the calcination process and further reduces the calcination cost of the calcining furnace.

[0031] In a preferred embodiment, the bottom of the gear 14 is rotatably connected to the top of the fixed platform 15 , a support rod is fixedly mounted on the bottom of the fixed platform 15 , and the bottom end of the support rod is fixedly mounted on the top of the collecting hopper 7 .

[0032] In the above structure, by setting up the fixed platform 15 and the support rod structure, the fixed platform 15 is fixedly connected to the collecting hopper 7 under the action of the support rod, so that the motor 2 5 can stably drive the gear 14 and the rotating rod 10 to rotate after installation, thereby realizing the effect of automatic feeding and automatic cleaning of bonded materials, thereby improving the precision of the calcining furnace.

[0033] Working principle: first, after the user assembles the calcining furnace, the gear 14 is driven to rotate by the motor 2 5 so that the position of the circular hole 1 and the feeding pipe 9 are in a state of overlap, and then the material is fed into the collecting hopper 7 through the feeding pipe 9, and then the rotating rod 10 is driven to rotate by the motor 2 5 again, so that the scraper 11 scrapes the inner wall of the collecting hopper 7 to ensure that the material cannot stick to the inner wall of the collecting hopper 7, and at the same time, the threaded feeding rod is driven by the motor 1 4 to transport the fallen material to the main body 1 for calcination, thereby realizing the effect of automatic feeding. During the calcination process, the heat will gradually be transferred to the furnace tube 8, so that part of the heat is transferred to the inside of the collecting hopper 7. At this time, the feeding pipe 9 will be sealed during the rotation of the sealing shell 6, thereby ensuring that the heat cannot escape to the outside in large quantities, thereby improving the sealing effect of the calcining furnace.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
