Description

Technical Field

[0001] The utility model relates to the technical field of nitrocotton alcohol-based solid alcohol production, in particular to automated production equipment for nitrocotton alcohol-based solid alcohol. Background Art

[0002] The traditional nitrocellulose alcohol-based solid alcohol production process involves multiple steps from preparing the nitrocellulose stock solution to the finished product: adding methanol, adding nitrocellulose, soaking, stirring, adding coarse methanol for stirring, pouring into a large mold, preparing a release agent, soaking the shaping mold in release agent, inserting the shaping mold into the large mold, transferring to the water-cotton exchange area, spraying once, spraying twice (or even three times), lifting out the shaping mold, transferring the formed round (square) strip semi-finished product to the packaging machine, manually removing it and placing it on the slicer, packaging, weighing, and finally finishing it. This process is complex and outdated, resulting in complex production equipment. Furthermore, due to the numerous production links, the process is long, and there are significant breakpoints between each link, leaving significant room for improvement in production continuity.

[0003] Similarly, CN112552974A, a method for preparing nitrocellulose-based solid alcohol, comprises the following steps: first, mixing methanol having a mass concentration of 97% or more with nitrocellulose, allowing the mixture to stand and stir for 30 minutes to completely dissolve the nitrocellulose; then adding methanol having a mass concentration of 85% or more and stirring until the mixture is completely dissolved again; then pouring the mixture into a cylindrical permeable membrane, sealing the mixture, and soaking it in water to solidify it; then removing the resulting cylindrical solid alcohol from the permeable membrane, slicing it, and packaging the flaky solid alcohol into bags. This method also has low production continuity and low production capacity. Utility Model Content

[0015] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0016] like Figure 1 and 2 As shown, an automated production equipment for nitrocellulose alcohol-based solid alcohol includes an alcohol storage tank 1, the outlet of the alcohol storage tank 1 is connected to the inlet of a stirred reactor 2 through a pipeline, a nitrocellulose feeding box 3 is provided on the top of the stirred reactor 2, the air outlet of the stirred reactor 2 is connected to the air inlet of a condenser 4 through a pipeline, the reflux port of the condenser 4 is connected to the inlet of a crude alcohol metering tank 5 through a pipeline, the crude alcohol metering tank 5 is connected to the reflux port of the stirred reactor 2 through a pipeline, and the discharge port of the stirred reactor 2 is connected to a solid alcohol forming device 6 through a pipeline.

[0017] Preferably, the solid alcohol forming device 6 comprises a forming mold 6.1 and a soaking and shaping tank 6.2, and a water spray head 6.3 is provided above the forming mold 6.1. The water spray head 6.3 can pre-condense the outer surface of the nitrocellulose alcohol.

[0018] Preferably, the forming mold 6.1 includes an outer forming cup body 6.1.1 and an inner foam brick layer 6.1.2. The foam brick layer 6.1.2 can absorb some water. In this way, the water sprayed by the water spray head 6.3 not only reaches the top of the nitrocellulose alcohol, but also penetrates through the foam brick layer 6.1.2 into the bottom and sides of the nitrocellulose alcohol in the forming cup body 6.1.1, so that the top, bottom, and sides of the nitrocellulose alcohol can all be exposed to water and begin to condense and form.

[0019] Preferably, the forming mold 6.1 is installed on the surface of the conveyor device 6.4, an immersion and shaping pool 6.2 is provided on the lower side of the conveyor device 6.4, and a material box 6.5 is provided on the upper side of the conveyor device 6.4. The injection molding and demoulding processes can be carried out continuously through the conveyor device 6.4, specifically: the conveyor device 6.4 can drive the forming mold 6.4 to rotate in a circular manner, first spraying an appropriate amount of water into the forming mold 6.4 through the water spray head 6.3, so that the nitrocellulose alcohol can be solidified and the demoulding process can be facilitated; then the forming mold 6.4 located on the upper side of the conveyor device 6.4 receives the nitrocellulose alcohol from the material box 6.5, and after continuing to spray an appropriate amount of water into the forming mold 6.4 through the water spray head 6.3, the water can be sprayed along the foam The brick layer 6.1.2 penetrates into the bottom and sides of the nitrocellulose alcohol in the forming cup body 6.1.1, allowing the top, bottom, and sides of the nitrocellulose alcohol to come into contact with water and begin to condense and form. As the conveyor belt device 6.4 rotates, the forming mold 6.4 on the upper side of the conveyor belt device 6.4 rotates to the lower side. The nitrocellulose alcohol initially formed in the forming mold 6.4 is separated from the mold by gravity and enters the immersion and setting tank 6.2 (which contains 70-80% methanol solution), thereby completing full setting.

[0020] Preferably, a bucket elevator is also provided on one side of the immersion and shaping tank 6.2. The bucket elevator can continuously lift and transport the solidified nitrocellulose alcohol solids in the immersion and shaping tank 6.2, and then send them to the packaging line via a subsequent conveyor belt to complete the packaging and whole-box packaging. In addition, to facilitate the lifting process of the bucket elevator, a horizontal conveyor belt can also be provided at the bottom of the immersion and shaping tank 6.2 to transport the shaped nitrocellulose alcohol solids to the starting point of the bucket elevator and then lift and transport them out. A circulating pump can also be provided at the bottom of the immersion and shaping tank 6.2, with the inlet and outlet of the circulating pump located at both ends of the immersion and shaping tank 6.2, so that a one-way flow is formed in the tank, and the alcohol solids are transported from one end to the inlet of the bucket elevator through the flow in the tank.

[0021] Preferably, there are two stirred reactors 2. The production capacity can be further increased by providing two stirred reactors 2.

[0022] Preferably, the liquid outlet of the soaking and setting tank 6.2 is also connected to the inlet of the crude alcohol metering tank 5 via a reflux line 7. The soaking and setting tank 6.2 itself is filled with 70-80% methanol solution. If there is too much 70-80% methanol solution in the soaking and setting tank 6.2, it can be passed to the crude alcohol metering tank 5 through the reflux line 7 for reuse.

[0023] More preferably, a closed shell structure can be set on the outside of the solid alcohol forming device 6 to minimize the volatilization of alcohol, improve the utilization rate of raw materials and reduce safety seals. The closed shell is provided with a transparent observation hole to facilitate observation of the production process.

[0024] The working principle of this embodiment is as follows:

[0025] The raw materials for making solid alcohol fuel are stored in the alcohol storage tank 1. During production, the alcohol fuel (mainly methanol) is first transported to the stirred reactor 2 through a feed pump. The stirred reactor 2 is provided with a stirring device. After the liquid level in the stirred reactor 2 meets the requirements, the corresponding weight of nitrocellulose is gradually added into the stirred reactor 2 through the nitrocellulose feeding box 3 at the upper end of the stirred reactor 2. During the operation of the stirred reactor 2, part of the alcohol fuel will evaporate and then enter the condenser 4, thereby condensing and recovering the gas after the alcohol fuel evaporates. The condensed liquid is passed into the crude alcohol metering tank 5 for accumulation, further improving the utilization rate of the raw materials. The crude alcohol fuel in the metering tank 5 can be added into the stirred reactor 2 in an appropriate amount to realize the recycling of raw materials. After the nitrocellulose and the alcohol fuel in the stirred reactor 2 are fully and evenly blended under the action of the stirring device, the nitrocellulose alcohol-based alcohol stock solution is sent into the material box 6.5 through the discharge pump; the injection molding and demoulding process can be continuously carried out through the conveyor device 6.4. Specifically, the conveyor device 6.4 can drive the forming mold 6.4 to rotate in a cycle, and first spray an appropriate amount of water into the forming mold 6.4 through the water spray head 6.3 to facilitate the demoulding process after the nitrocellulose alcohol-based alcohol is solidified; then the conveyor device 6.4 is located on the upper side of the conveyor device 6.4. The forming mold 6.4 receives the nitrocellulose alcohol from the material box 6.5, and after the water spray head 6.3 continues to spray an appropriate amount of water to the forming mold 6.4, the water can penetrate into the bottom and side of the nitrocellulose alcohol in the forming cup body 6.1.1 along the foam brick layer 6.1.2, so that the top, bottom and side positions of the nitrocellulose alcohol can all contact with the water and begin to condense and form; as the conveyor belt device 6.4 rotates, the forming mold 6.4 on the upper side of the conveyor belt device 6.4 rotates to the lower side, and the nitrocellulose alcohol initially formed in the forming mold 6.4 is separated from the mold due to gravity and enters the soaking The shaping tank 6.2 (which contains 70-80% methanol solution) is used to fully shape the solidified nitrocellulose alcohol solids in the immersion and shaping tank 6.2. The solidified nitrocellulose alcohol solids in the immersion and shaping tank 6.2 can be continuously lifted and transported out by a bucket elevator, and then sent to the packaging line through a subsequent conveyor belt to complete the packaging and whole-case packaging. In addition, in order to facilitate the lifting process of the bucket elevator, a circulation pump can also be set at the bottom of the immersion and shaping tank 6.2. The inlet and outlet of the circulation pump are respectively located at both ends of the immersion and shaping tank 6.2, so that a unidirectional flow is formed in the tank. Through the flow in the tank, the alcohol solids reach the inlet end of the bucket elevator from one end, and then are lifted and transported out.
