Description

Technical Field

[0001] This invention relates to the field of oil shale retorting equipment technology, specifically to a heating furnace for an oil shale retorting equipment. Background Technology

[0002] The main direction of oil shale development and utilization is oil extraction through dry distillation. Dry distillation is divided into aboveground dry distillation and underground dry distillation, and in my country, aboveground dry distillation is still the dominant method. Aboveground dry distillation is further divided into gaseous heat carrier processes and solid heat carrier processes according to different heat transfer methods. Due to its simple process, mature technology, and stable operation, the gaseous heat carrier process has become the mainstream production process for industrialized shale dry distillation.

[0003] In practical use, the gas heat carrier process will generate a large amount of mixed gas containing substances such as methane, olefins, tar, and water vapor, as well as a large number of suspended particles. During the flow of the mixed gas, water vapor and suspended particles will mix and adhere to the outlet gas position. Since the outlet pipe needs to discharge a large amount of mixed gas in a short period of time, this will cause the flow orifice of the outlet pipe to narrow in a short period of time. To address the above problems, the following solutions are proposed. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a heating furnace for an oil shale retorting device, including a base, an insulation layer fixedly connected to the top of the base, a feed pipe fixedly connected to the end of the insulation layer away from the base, an inner shell fixedly connected to the center of the top of the base, and a crusher fixedly connected to the center of the top of the base, and further including: Radiation mechanism, which is fixedly installed on the side wall of the inner shell; Auxiliary mechanism, which is fixedly installed on the inner wall of the inner shell; A rotating mechanism is fixedly installed on the outer wall of the radiation mechanism. During operation, the feed pipe pours the crushed oil shale into the inner shell. Under high temperature, the oil shale produces semi-coke and gas. The semi-coke and gas are refined into combustible gas by the external horizontal rotary distillation kettle integrated preheating kettle and semi-coke combustion furnace through the radiation mechanism. The combustible gas is then returned to the inner shell for combustion through the radiation mechanism to form a stable heat source. The falling oil shale will be completely crushed by the crusher.

[0005] Preferably, the radiation mechanism includes: The transmission component is fixedly installed on the outer wall of the insulation layer; Heating component, which is fixedly installed on the inner wall of the inner shell; The transmission component extracts the semi-coke and gas from the inner shell and feeds them into a horizontal rotary distillation kettle integrated with a preheating kettle and a semi-coke combustion furnace to refine them into combustible gas.

[0006] Preferably, the auxiliary mechanism includes: A separator assembly is fixedly installed at the bottom of the heating assembly; A limiting component is fixedly installed on the inner wall of the inner shell; In this process, combustible gas is transported through a transmission component to the interior of a heating component, a separation component, and a confinement component, forming a stable combustion process.

[0007] Preferably, the rotating mechanism includes: The lifting component is fixedly installed on the inner wall of the heating component; The push component is fixedly mounted on the side wall of the raised component; The rotating mechanism consists of two sets, one set fixedly installed inside the heating component and the other set fixedly installed inside the limiting component.

[0008] Preferably, the transmission assembly includes a discharge pipe fixedly disposed on the side wall of the inner shell, a collection tray fixedly connected to the end of the discharge pipe, and an input pipe fixedly connected to the side wall of the inner shell. The input tube has a single inlet and three outlets.

[0009] Preferably, the heating assembly includes a chamber 1 fixedly connected to the inner wall of the inner shell, a friction groove 1 is provided on the inclined surface of the inner wall of the chamber 1, and a spring telescopic rod 1 is fixedly connected to the inner wall of the central through hole of the chamber 1, with the end of the spring telescopic rod 1 away from the chamber 1 fixedly connected to the inner wall of the collection tray. The inner wall of chamber one is equipped with a combustion chamber. Combustible gas is transmitted to the inside of chamber one through an input pipe and is burned inside chamber one, releasing heat.

[0010] Preferably, the partition assembly includes a spring telescopic rod 2 fixedly connected to the bottom of the chamber 1, and a fan-shaped chamber fixedly connected to the end of the spring telescopic rod 2 away from the chamber 1, and a friction groove 2 is provided on the outer wall of the fan-shaped chamber; Under normal conditions, both spring telescopic rod 2 and spring telescopic rod 1 are in an extended state.

[0011] Preferably, the limiting component includes a second chamber fixedly connected to the inner wall of the inner shell, and a third friction groove is provided on the inclined surface of the inner wall of the second chamber; Combustion chambers are provided on the inner walls of the sector-shaped chamber and the second chamber, and the three output ports of the input pipe are connected to the second chamber, the sector-shaped chamber and the first chamber, respectively.

[0012] Preferably, the lifting assembly includes a polygonal bracket fixedly connected to the inner wall of the friction groove, and a plurality of rotating plates are rotatably connected to the outer wall of the polygonal bracket; Among them, a torsion spring is fixedly connected to the connection position between the polygonal bracket and the rotating plate. Under normal conditions, the torsion spring drives the end of the rotating plate to stick tightly to the outer wall of the friction groove. When the gap between the friction groove and the rotating plate stores excessive oil shale, the rotating plate will be pressed outward.

[0013] Preferably, the pushing assembly includes a fixed plate fixedly connected to the side wall of the rotating plate, a pushing rod rotatably connected to the inner wall of the groove of the fixed plate, and a pressure frame rotatably connected to the end of the pushing rod away from the fixed plate; Among them, the pressure frame in friction groove one is fixedly connected to the sliding end of spring telescopic rod one, and the pressure frame inside chamber two is fixedly connected to the bottom of the sector-shaped chamber.

[0014] The present invention has the following beneficial effects: (1) In view of the problem that the flow diameter of the inner wall of the gas outlet pipe is reduced due to excessive gas flow, the present invention is equipped with a heating component inside the equipment. The design of the first chamber, the fan-shaped chamber and the second chamber is used for outward heat radiation. When the oil shale falls from the feed pipe, the oil shale will spread on the outer wall of the collection plate and fall on the inner wall slope of the first chamber. The oil shale on the inner wall slope of the first chamber falls down to the outer surface of the fan-shaped chamber through the central through hole. Affected by the top slope of the fan-shaped chamber, it falls to the inner wall slope of the friction groove three and finally falls into the crusher to complete the crushing process. Through the application of the above components, compared with the traditional gas heat carrier process, the total amount of gas inside the inner shell will be greatly reduced. (2) The present invention utilizes the characteristics of the oil shale passing through the first chamber, the fan-shaped chamber and the second chamber. Friction groove 1, friction groove 3 and friction groove 2 are set inside the equipment. When the oil shale falls from top to bottom and passes through the above-mentioned positions, it will move downward in the form of rolling due to the friction of friction groove 1, friction groove 3 and friction groove 2. Due to the irregular shape of the oil shale, the oil shale will roll randomly on the outer wall of friction groove 1. Through the application of the above components, the oil shale is heated evenly. (3) In view of the problem that the rolling speed of oil shale is inconsistent, resulting in uneven heating time, the present invention is equipped with a lifting component inside the equipment. When the oil shale passes the outer wall of the collection plate, the oil shale will spread to the surroundings and eventually roll down along the outer wall of the first friction groove. During this process, most of the oil shale will accumulate in the gap between the rotating plate and the first friction groove. As the amount of oil shale below the feed pipe increases, the amount of accumulation will continue to increase, and the rotating plate will also bear more pressure. When the pressure is greater than the rotational force of the torsion spring, the rotating plate will open outward, causing the oil shale to fall down. At the same time, the same lifting component is installed inside the third friction groove. Through the application of the above components, the oil shale is effectively intercepted for a short time, ensuring the heating time of the oil shale. (4) This invention utilizes the characteristic that the oil shale needs to enter the inner shell through the feed pipe. A pushing component is set inside the equipment. When the total amount of material falling through the feed pipe in a short time exceeds the preset total amount, the collecting plate will bear an excessive downward pressure. This pressure will force the spring telescopic rod to contract. The spring telescopic rod will drive the pressure frame to move down synchronously. The pressure frame will drive the rotating plate and the fixed plate polygonal support to rotate clockwise around the center through the pushing rod, so that the end of the rotating plate is away from the outer wall of the friction groove. Similarly, when the sector chamber bears excessive pressure, the sector chamber will force the fixed plate and the rotating plate to open outward around the polygonal support through the pressure frame and the pushing rod. Through the application of the above components, it is ensured that when too much material enters the equipment at one time, the equipment will directly release the material between the rotating plate and the friction groove, preventing the phenomenon of material blockage.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1, please refer to Figure 1 - Figure 9 This invention relates to a heating furnace for an oil shale dry distillation apparatus, comprising a base 13, a heat insulation layer 14 fixedly connected to the top of the base 13, a feed pipe 15 fixedly connected to the end of the heat insulation layer 14 away from the base 13, an inner shell 16 fixedly connected to the center of the top of the base 13, and a crusher 17 fixedly connected to the center of the top of the base 13, and further comprising: Radiation mechanism 1 is fixedly installed on the side wall of the inner shell 16; Auxiliary mechanism 2 is fixedly installed on the inner wall of the inner shell 16; Rotating mechanism 3 is fixedly installed on the outer wall of radiation mechanism 1; During use, the feed pipe 15 pours the crushed oil shale into the inner shell 16. Under high temperature, the oil shale produces semi-coke and gas. The semi-coke and gas are refined into combustible gas by the external horizontal rotary distillation kettle integrated preheating kettle and semi-coke combustion furnace through the radiation mechanism 1. The combustible gas is then returned to the inner shell 16 through the radiation mechanism 1 for combustion, forming a stable heat source. The falling oil shale will be completely crushed by the crusher 17.

[0020] Radiation mechanism 1 includes: Transmission component 11 is fixedly disposed on the outer wall of the heat insulation layer 14; Heating component 12 is fixedly disposed on the inner wall of inner shell 16; The transmission component 11 extracts the semi-coke and gas inside the inner shell 16 and feeds them into the horizontal rotary distillation kettle integrated preheating kettle and semi-coke combustion furnace to refine them into combustible gas.

[0021] Auxiliary mechanism 2 includes: The partition component 21 is fixedly disposed at the bottom of the heating component 12; Restriction component 22 is fixedly disposed on the inner wall of the inner shell 16; In this process, combustible gas is transferred through the transmission component 11 to the interior of the heating component 12, the separation component 21 and the confinement component 22, forming a stable combustion process.

[0022] Rotating mechanism 3 includes: The lifting component 31 is fixedly disposed on the inner wall of the heating component 12; Push component 32 is fixedly mounted on the side wall of the lifting component 31; The rotating mechanism 3 consists of two sets, one set is fixedly installed inside the heating component 12, and the other set is fixedly installed inside the limiting component 22.

[0023] Example 2, please refer to Figure 4 - Figure 11 The present invention is a heating furnace for an oil shale dry distillation device. Based on Example 1, the transmission component 11 includes a discharge pipe 111 fixedly disposed on the side wall of the inner shell 16, a collection tray 112 fixedly connected to the end of the discharge pipe 111, and an input pipe 113 fixedly connected to the side wall of the inner shell 16. The input tube 113 has a single inlet and three outlets.

[0024] The heating assembly 12 includes a chamber 121 fixedly connected to the inner wall of the inner shell 16. A friction groove 122 is provided on the inclined surface of the inner wall of the chamber 121. A spring telescopic rod 123 is fixedly connected to the inner wall of the central through hole of the chamber 121. The end of the spring telescopic rod 123 away from the chamber 121 is fixedly connected to the inner wall of the collection tray 112. First, the equipment is fixed in the required position. Then, the feed pipe 15 pours the crushed oil shale into the inner shell 16. Under high temperature, the oil shale produces semi-coke and gas. The semi-coke and gas are extracted outward through the collection plate 112 and the discharge pipe 111 and enter the horizontal rotary distillation kettle integrated preheating kettle and semi-coke combustion furnace to be refined into combustible gas. The combustible gas is returned to the chamber 121 through the input pipe 113 and undergoes stable combustion. The heat generated will radiate outward and continuously heat the oil shale inside the inner shell 16. Finally, the falling oil shale will be completely crushed by the crusher 17 and discharged outward.

[0025] The partition assembly 21 includes a spring telescopic rod 211 fixedly connected to the bottom of the first chamber 121. The end of the spring telescopic rod 211 away from the first chamber 121 is fixedly connected to a fan-shaped chamber 212. A friction groove 213 is provided on the outer wall of the fan-shaped chamber 212. To address the issue of reduced flow orifice diameter due to excessive gas flow, a heating component 12 is installed inside the equipment. This component features a design that allows for outward heat radiation from three chambers: chamber one 121, fan-shaped chamber 212, and chamber two 221. As the oil shale falls from the feed pipe 15, it diffuses on the outer wall of the collection tray 112 and falls onto the inclined inner wall of chamber one 121. The oil shale on the inclined inner wall of chamber one 121 falls through the central through-hole onto the outer surface of the fan-shaped chamber 212. Influenced by the inclined top of the fan-shaped chamber 212, it falls onto the inclined inner wall of the friction groove three 222 and finally enters the crusher 17, completing the crushing process. By applying the above components, the total amount of gas inside the inner shell 16 is significantly reduced compared to traditional gas heat carrier processes. The limiting component 22 includes a second chamber 221 fixedly connected to the inner wall of the inner shell 16, and a third friction groove 222 is provided on the inclined surface of the inner wall of the second chamber 221. Taking advantage of the characteristics of the oil shale passing through chamber 121, fan-shaped chamber 212, and chamber 221, friction grooves 122, 322, and 213 are provided inside the equipment. When the oil shale falls from top to bottom and passes through the above-mentioned positions, it will roll downwards due to the friction of friction grooves 122, 322, and 213. Due to the irregular shape of the oil shale, it will roll freely on the outer wall of friction groove 122. The application of the above components ensures that the oil shale is heated evenly.

[0026] The lifting assembly 31 includes a polygonal bracket 311 fixedly connected to the inner wall of the friction groove 122, and a plurality of rotating plates 312 rotatably connected to the outer wall of the polygonal bracket 311. To address the issue of uneven heating time caused by inconsistent rolling speed of oil shale, a lifting component 31 is installed inside the equipment. When the oil shale passes the outer wall of the collection plate 112, it spreads outwards and eventually rolls down along the outer wall of the friction groove 122. During this process, most of the oil shale accumulates in the gap between the rotating plate 312 and the friction groove 122. As the amount of oil shale below the feed pipe 15 increases, the accumulation increases, and the rotating plate 312 bears more pressure. When the pressure exceeds the rotational force of the torsion spring, the rotating plate 312 will open outwards, causing the oil shale to fall downwards. At the same time, the friction groove 222 is equipped with the same lifting component 31. Through the application of the above components, the oil shale is effectively intercepted temporarily, ensuring the heating time of the oil shale.

[0027] The pushing assembly 32 includes a fixed plate 321 fixedly connected to the side wall of the rotating plate 312, a pushing rod 322 rotatably connected to the inner wall of the groove of the fixed plate 321, and a pressure frame 323 rotatably connected to the end of the pushing rod 322 away from the fixed plate 321. Taking advantage of the fact that the oil shale needs to enter the inner shell 16 through the feed pipe 15, a pushing component 32 is installed inside the equipment. When the total amount of material falling through the feed pipe 15 in a short period of time exceeds the preset total amount, the collecting plate 112 will be subjected to excessive downward pressure. This pressure will force the spring telescopic rod 123 to contract, and the spring telescopic rod 123 will drive the pressure frame 323 to move downward synchronously. The pressure frame 323, through the pushing rod 322, drives the fixed plate 321 and the rotating plate 312 to move around the polygonal support 311 as the center. The rotating plate 312 rotates clockwise, causing its end to move away from the outer wall of the friction groove 122. Similarly, when the sector chamber 212 is subjected to excessive pressure, the sector chamber 212 forces the fixed plate 321 and the rotating plate 312 to open outward around the polygonal support 311 through the pressure frame 323 and the push rod 322. Through the application of the above components, the equipment will directly release the material between the rotating plate 312 and the friction groove 122 when too much material enters the equipment at one time, thus preventing material blockage.

[0028] A specific application of this embodiment is as follows: Before use, the equipment is fixedly set in the required position. Then, the feed pipe 15 pours the crushed oil shale into the inner shell 16. Under high temperature, the oil shale produces semi-coke and gas. The semi-coke and gas are extracted outward through the collection plate 112 and the discharge pipe 111 and enter the horizontal rotary distillation kettle integrated preheating kettle and semi-coke combustion furnace to refine into combustible gas. The combustible gas is returned to the interior of chamber one 121, fan-shaped chamber 212 and chamber two 221 through the input pipe 113 and undergoes stable combustion. The heat generated will radiate outward and continuously heat the oil shale inside the inner shell 16. Finally, the falling oil shale will be completely crushed by the crusher 17 and discharged outward.

[0029] To address the issue of reduced flow orifice diameter due to excessive gas flow, a heating component 12 is installed inside the equipment. This component features a design that allows for outward heat radiation from three chambers: chamber one 121, fan-shaped chamber 212, and chamber two 221. As the oil shale falls from the feed pipe 15, it diffuses on the outer wall of the collection tray 112 and falls onto the inclined inner wall of chamber one 121. The oil shale on the inclined inner wall of chamber one 121 falls through the central through-hole onto the outer surface of the fan-shaped chamber 212. Influenced by the inclined top of the fan-shaped chamber 212, it falls onto the inclined inner wall of the friction groove three 222 and finally enters the crusher 17, completing the crushing process. By applying the above components, the total amount of gas inside the inner shell 16 is significantly reduced compared to traditional gas heat carrier processes. Taking advantage of the characteristics of the oil shale passing through chamber 121, fan-shaped chamber 212, and chamber 221, friction grooves 122, 322, and 213 are provided inside the equipment. When the oil shale falls from top to bottom and passes through the above-mentioned positions, it will roll downwards due to the friction of friction grooves 122, 322, and 213. Due to the irregular shape of the oil shale, it will roll freely on the outer wall of friction groove 122. The application of the above components ensures that the oil shale is heated evenly.

[0030] To address the issue of uneven heating time caused by inconsistent rolling speed of oil shale, a lifting component 31 is installed inside the equipment. When the oil shale passes the outer wall of the collection plate 112, it spreads outwards and eventually rolls down along the outer wall of the friction groove 122. During this process, most of the oil shale accumulates in the gap between the rotating plate 312 and the friction groove 122. As the amount of oil shale below the feed pipe 15 increases, the accumulation increases, and the rotating plate 312 will bear more pressure. When the pressure exceeds the rotational force of the torsion spring, the rotating plate 312 will open outwards, causing the oil shale to fall downwards. At the same time, the friction groove 222 is equipped with the same lifting component 31. Through the application of the above components, the oil shale is effectively intercepted temporarily, ensuring the heating time of the oil shale. Taking advantage of the fact that the oil shale needs to enter the inner shell 16 through the feed pipe 15, a pushing component 32 is installed inside the equipment. When the total amount of material falling through the feed pipe 15 in a short period of time exceeds the preset total amount, the collecting plate 112 will be subjected to excessive downward pressure. This pressure will force the spring telescopic rod 123 to contract, and the spring telescopic rod 123 will drive the pressure frame 323 to move downward synchronously. The pressure frame 323, through the pushing rod 322, drives the fixed plate 321 and the rotating plate 312 to move around the polygonal support 311 as the center. The rotating plate 312 rotates clockwise, causing its end to move away from the outer wall of the friction groove 122. Similarly, when the sector chamber 212 is subjected to excessive pressure, the sector chamber 212 forces the fixed plate 321 and the rotating plate 312 to open outward around the polygonal support 311 through the pressure frame 323 and the push rod 322. Through the application of the above components, the equipment will directly release the material between the rotating plate 312 and the friction groove 122 when too much material enters the equipment at one time, thus preventing material blockage.
