Description

Technical Field

[0001] This utility model relates to a device for reducing the temperature of dry distillation, and belongs to the field of dry distillation technology. Background Technology

[0002] Dry distillation is a reaction process in which solids or organic substances are heated and decomposed under air-isolated conditions. The result of dry distillation is the production of various gases, vapors, and solid residues. The mixture of gases and vapors is separated into gases and liquids after cooling. Dry distillation is a production process that humans have been familiar with and used for a long time. For example, dry distilling wood to make charcoal also yields wood spirits (methanol), wood acetic acid, etc.

[0003] Chinese Patent Publication No. CN 205115375 U discloses a dry distillation apparatus, characterized by comprising a heating furnace body, a furnace cylinder, at least one heat-conducting partition plate, a furnace cover, and a gas collecting pipe. The purpose of this invention is to provide a dry distillation apparatus that uses at least one heat-conducting partition plate to separate the substances to be dry distilled within the furnace cylinder. The partition plate contacts the side wall of the furnace cylinder, allowing heat from the heating furnace body and furnace cylinder to be transferred through multiple pathways via the partition plate, ultimately reaching the substances to be dry distilled on both sides of each partition plate. This design significantly increases the heat transfer rate and heat conduction area, effectively improving heat transfer efficiency and enabling the dry distillation process to proceed rapidly and efficiently, greatly improving the efficiency of oil and gas production. The pyrolysis oil and gas generated during the dry distillation process are quickly discharged to the outside of the furnace cylinder through multiple gas collecting holes inside the furnace cylinder, shortening the residence time of the oil and gas within the dry distillation apparatus, reducing secondary cracking of tar, and effectively improving the quality of the oil and gas.

[0004] The aforementioned device is not equipped with a cooling device. After the dry distillation is completed, the internal temperature of the furnace is high. At this time, it is not possible to directly discharge the dry distilled material inside. Waiting for it to cool naturally will take a lot of time. At the same time, during the dry distillation of materials such as oil sludge, high bituminous biomass, and oil-bearing shale, the materials are prone to softening, melting, or coking during the pyrolysis process and adhering to the inner wall of the furnace, which may affect the heat transfer and make it inconvenient for operators to use.

[0005] Therefore, a device for lowering the distillation temperature is proposed. Utility Model Content

[0006] In view of this, the present invention provides an apparatus for reducing the distillation temperature to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial alternative.

[0007] The technical solution of this utility model is implemented as follows: a device for reducing the temperature of dry distillation includes a dry distillation furnace. The top of the dry distillation furnace is provided with a furnace cover. A vacuum valve is fixedly installed on the left side of the top of the furnace cover, and a one-way air inlet valve is fixedly installed on the right side of the top of the furnace cover. A discharge valve is fixedly installed at the bottom of the dry distillation furnace. Support rods are fixedly installed around the bottom of the dry distillation furnace. A heating chamber is opened on the inner surface of the dry distillation furnace. A heating tube is fixedly installed in the inner cavity of the heating chamber. A cleaning assembly is provided on the top of the dry distillation furnace. The cleaning assembly includes a drive motor and a linkage gear. The drive motor is fixedly installed on the surface of the furnace cover. The linkage gear is movably connected to the top of the furnace cover. A rotating frame is fixedly installed at the bottom of the linkage gear. Vertical rods are fixedly installed at the bottom of each of the three vertical rods. Scrapers are provided on the outer sides of each of the three vertical rods. The scrapers are attached to the inner wall of the dry distillation furnace.

[0008] More preferably, the output end of the drive motor is fixedly connected to a mounting shaft, and a transmission gear is fixedly mounted on the front side of the mounting shaft, the surface of the transmission gear meshing with the surface of the linkage gear.

[0009] More preferably, each of the three vertical rods has a slot on its surface, the inner side of each of the three scrapers is engaged in the inner cavity of the three slots, and each of the three vertical rods has a threaded mounting bolt on its surface, the outer side of the mounting bolt being threaded to the inner surface of the scraper.

[0010] More preferably, the surface of the mounting shaft is movably connected to a support plate via a bearing, and the bottom of the support plate is fixedly mounted to the top of the furnace cover.

[0011] More preferably, the top of the furnace cover is threaded with fixing bolts, and the bottom of the fixing bolts is threaded to the inner surface of the dry distillation furnace.

[0012] More preferably, a pressure sensor is fixedly installed on the right side of the top of the furnace cover, and the detection end of the pressure sensor extends into the inner cavity of the dry distillation furnace.

[0013] More preferably, a temperature sensor is fixedly installed on the left side of the top of the furnace cover, and the detection end of the temperature sensor extends into the inner cavity of the dry distillation furnace.

[0014] The present invention has the following advantages due to the adoption of the above technical solution:

[0015] I. This utility model, by setting up a cleaning component, a vacuum valve, and a one-way air inlet valve, uses the output of a drive motor to cause the linkage gear to drive the scraper to move in a circular motion. The scraper can scrape off the material adhering to the inner wall of the dry distillation furnace, preventing the material from affecting the heat conduction of the heating tube. At the same time, through the cooperation of the vacuum valve and the one-way air inlet valve, the vacuum valve extracts the air from the inner cavity of the dry distillation furnace, and the reduced pressure will significantly lower the boiling point of the liquid. This allows volatile products to evaporate and escape at a lower temperature, and also lowers the temperature of the material in the inner cavity of the dry distillation furnace, thus achieving the goal of reducing the dry distillation temperature.

[0016] II. This utility model, by setting a slot and mounting bolts, allows for the replacement of the scraper after prolonged use, improving the ease of scraper disassembly and assembly. The support plate provides support for the mounting shaft, preventing it from falling off after extended use. The fixing bolts securely install the furnace cover onto the top of the distillation furnace, facilitating maintenance and repair of components within the furnace cavity. The pressure sensor allows for pressure monitoring within the furnace cavity, enabling operators to understand the pressure levels. Similarly, the temperature sensor allows for temperature monitoring within the furnace cavity, also providing operators with accurate temperature information.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] Example 1

[0028] like Figure 1-5 As shown, this utility model embodiment provides a device for reducing the temperature of dry distillation, including a dry distillation furnace 1. A furnace cover 3 is provided on the top of the dry distillation furnace 1. A vacuum valve 4 is fixedly installed on the left side of the top of the furnace cover 3, and a one-way air inlet valve 5 is fixedly installed on the right side of the top of the furnace cover 3. A discharge valve 6 is fixedly installed at the bottom of the dry distillation furnace 1. Support rods 7 are fixedly installed around the bottom of the dry distillation furnace 1. A heating chamber 11 is formed on the inner surface of the dry distillation furnace 1, and a heating tube 12 is fixedly installed in the inner cavity of the heating chamber 11. A cleaning assembly 2 is provided on the top of the dry distillation furnace 1. The cleaning assembly 2 includes a drive motor 201 and a linkage gear. The wheel 204 and drive motor 201 are fixedly installed on the surface of the furnace cover 3. The linkage gear 204 is movably connected to the top of the furnace cover 3. The bottom of the linkage gear 204 is fixedly installed with a rotating frame 205. The bottom of the rotating frame 205 is fixedly installed with vertical rods 206. Scrapers 207 are provided on the outer side of the three vertical rods 206. The scrapers 207 are attached to the inner wall of the dry distillation furnace 1. The output end of the drive motor 201 is fixedly connected with a mounting shaft 202. A transmission gear 203 is fixedly installed on the front side of the mounting shaft 202. The surface of the transmission gear 203 meshes with the surface of the linkage gear 204.

[0029] By setting up cleaning component 2, vacuum valve 4, and one-way air inlet valve 5, the output of drive motor 201 causes linkage gear 204 to drive scraper 207 to move in a circle. Scraper 207 can scrape off the material adhering to the inner wall of the dry distillation furnace 1, avoiding the impact of material adhesion on the heat conduction of heating tube 12. At the same time, through the cooperation of vacuum valve 4 and one-way air inlet valve 5, vacuum valve 4 extracts air from the inner cavity of dry distillation furnace 1. The reduced pressure will significantly lower the boiling point of liquids such as tar and water produced by pyrolysis. This allows volatile products to evaporate and escape at a lower temperature, and also reduces the temperature of the material in the inner cavity of dry distillation furnace 1, thereby achieving the work of reducing the dry distillation temperature.

[0030] Example 2

[0031] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in one embodiment, the surfaces of the three vertical rods 206 are all provided with slots 208, the inner sides of the three scrapers 207 are all engaged in the inner cavities of the three slots 208, the surfaces of the three vertical rods 206 are all threaded with mounting bolts 209, the outer sides of the mounting bolts 209 are threaded to the inner surfaces of the scrapers 207, the surface of the mounting shaft 202 is movably connected to a support plate 210 through a bearing, the bottom of the support plate 210 is fixedly installed on the top of the furnace cover 3, the top of the furnace cover 3 is threaded with fixing bolts 10, the bottom of the fixing bolts 10 is threaded to the inner surface of the dry distillation furnace 1, a pressure sensor 8 is fixedly installed on the right side of the top of the furnace cover 3, the detection end of the pressure sensor 8 extends into the inner cavity of the dry distillation furnace 1, and a temperature sensor 9 is fixedly installed on the left side of the top of the furnace cover 3, the detection end of the temperature sensor 9 extends into the inner cavity of the dry distillation furnace 1.

[0032] By setting the slot 208 and mounting bolt 209, the scraper 207 can be replaced after long-term use, improving the convenience of disassembly and assembly of the scraper 207. By setting the support plate 210, the mounting shaft 202 can be supported, preventing the mounting shaft 202 from falling off after long-term use. By setting the fixing bolt 10, the furnace cover 3 can be firmly installed on the top of the dry distillation furnace 1, and at the same time, it is convenient to maintain and repair the components in the inner cavity of the dry distillation furnace 1. By setting the pressure sensor 8, the pressure in the inner cavity of the dry distillation furnace 1 can be detected, making it convenient for operators to understand the pressure in the inner cavity of the dry distillation furnace 1. By setting the temperature sensor 9, the temperature in the inner cavity of the dry distillation furnace 1 can be detected, making it convenient for operators to understand the temperature in the inner cavity of the dry distillation furnace 1.

[0033] In operation, this invention controls the pressure inside the furnace 1 by coordinating the outputs of the vacuum valve 4 and the one-way inlet valve 5. This pressure significantly lowers the boiling point of the material inside the furnace 1, thus reducing the distillation temperature. This allows volatile products to evaporate at a lower temperature. The drive motor 201 outputs power, and the mounting shaft 202 drives the transmission gear 203 to rotate. This causes the linkage gear 204 to drive the rotating frame 205 to rotate. The vertical rod 206 and the scraper 207 move circumferentially. The scraper 207 scrapes off the material adhering to the inner wall of the furnace 1, thus cleaning the inner wall of the furnace 1.

[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
