Description

Technical Field

[0001] The utility model embodiment relates to the field of equipment disinfection, and in particular to a nitrogen filling device. Background Art

[0002] The production equipment of cigarette factories has a complex structure. During the cigarette production process, tobacco and smoke will accumulate inside the equipment. The location where the tobacco and smoke accumulate is difficult to clean, such as being unable to be disassembled or being difficult to clean at a tricky angle. Once tobacco worms breed in the accumulated tobacco or smoke, they will directly infect the tobacco, reduce the quality of cigarettes, and cause complaints about the quality of worm-infected cigarettes.

[0003] At present, tobacco insect pest control and insect prevention are usually carried out by combining cleaning and maintenance with chemical disinfecting. For example, taking advantage of the opportunity of the whole factory stopping production, the production equipment of the cigarette factory is firstly cleaned and maintained, and then the production equipment of the cigarette factory is completely disinfected with chemical agents.

[0004] However, in order to avoid the adverse effects of smoke and chemicals on employees during cleaning and maintenance, this method of combining cleaning and maintenance with chemical disinfection requires the entire factory to stop production, which seriously affects normal production progress and reduces production efficiency. In addition, the locations where tobacco and smoke accumulate cannot be fully covered by chemicals, and there will be omissions and incomplete disinfection. It can be seen that this method of combining cleaning and maintenance with chemical disinfection is time-consuming and labor-intensive and cannot guarantee effective disinfection.

[0030] Embodiment 1

[0031] Figure 1 Schematic diagram of the structure of a nitrogen filling device provided in the first embodiment of the utility model. The nitrogen filling device provided in this embodiment is applied to a tobacco cigarette making machine and can be applied to the case where nitrogen is filled in the area wrapped by the wrapping layer. Figure 1 As shown, the nitrogen filling device includes: a first wrapping layer, a second wrapping layer, a nitrogen generator, an exhaust pipe, and a nitrogen filling pipeline connected to the nitrogen generator.

[0032] Among them, the first wrapping layer is used to wrap the tobacco cigarette making machine; the second wrapping layer is used to wrap the target frame, and the target frame including the second wrapping layer fully surrounds the tobacco cigarette making machine; the target frame is fixed on the ground at one end to fully surround the tobacco cigarette making machine when the target frame is in the target state; the exhaust pipe includes at least one pipeline, and at least one pipeline includes at least one ventilation pipe opening, which penetrates into the interior of the first wrapping layer and / or passes into the second wrapping layer, and is used to extract air in the first wrapping layer and / or the second wrapping layer; the nitrogen filling pipeline includes at least two nitrogen filling pipe openings, which penetrate into the interior of the first wrapping layer and / or into the second wrapping layer, and are used to fill the area wrapped by the first wrapping layer and / or the second wrapping layer with nitrogen when the nitrogen generator is in working state; the nitrogen generator is used to fill the area wrapped by the first wrapping layer and the second wrapping layer with nitrogen, so that the tobacco cigarette making machine is in a nitrogen environment.

[0033] Among them, the tobacco cigarette making machine may refer to a cigarette production device. The tobacco cigarette making machine can be used to produce cigarettes. The first wrapping layer may refer to a wrapping layer that wraps the tobacco cigarette making machine. The first wrapping layer may be configured based on the size and shape of the wrapped device, thereby reducing the amount of nitrogen filling in the excess space. The first wrapping layer has the ability to deform. In the case of no nitrogen filling and no air extraction, there may be a certain distance between the first wrapping layer and the tobacco cigarette making machine. After the nitrogen filling device starts working, the first wrapping layer can completely fit the tobacco cigarette making machine, and then in this environment, sufficient sterilization and insect removal can be carried out. The second wrapping layer may refer to a wrapping layer that wraps the tobacco cigarette making machine and the area where the tobacco cigarette making machine is located. The second wrapping layer may be configured based on the size of the area where the wrapped device is located, thereby reducing the amount of nitrogen filling in the excess space. For example, the second wrapping layer may cover the tobacco cigarette making machine and the area within one meter around the tobacco cigarette making machine. The target frame may refer to a frame that supports the second wrapping layer. The target frame may have a variety of structures. The target frame may be, but is not limited to, a splicing structure and a telescopic structure. For example, if the target structure is a splicing result, the shape and size of the target frame can be adjusted based on the different shapes and sizes of each device, so that various types of devices can be wrapped in a targeted manner, further reducing the amount of nitrogen filling in the excess space. The target state can refer to a state in which the target frame completely surrounds the device to be filled with nitrogen.

[0034] Among them, the exhaust pipe can be connected to the first package layer and the second package layer respectively through two ventilation pipe openings on the same pipeline. The exhaust pipe is also connected to the first package layer through the ventilation pipe opening on one pipeline, and connected to the second package layer through the ventilation pipe opening on another pipeline. Each package layer can correspond to at least one pipeline and at least one ventilation pipe opening on each pipeline. For example, if the volume of the wrapped equipment is too large, making the package layer too large, multiple pipelines can be used to communicate with the package layer, and the gas in the package layer can be extracted at the same time to further improve the gas extraction efficiency. The nitrogen generator may refer to a device for manufacturing nitrogen. The nitrogen filling pipeline of the nitrogen generator includes at least two nitrogen filling pipe openings. Each package layer corresponds to at least one nitrogen filling pipe opening. The nitrogen environment may refer to an environment where tobacco worms cannot survive for a long time. For example, the nitrogen environment may refer to an environment filled with a certain concentration of nitrogen in the package layer.

[0035] Specifically, a nitrogen filling plan is determined based on the insect situation of the tobacco cigarette machine to be filled with nitrogen. For example, the nitrogen filling plan may include a first nitrogen filling concentration to be achieved in the first wrapping layer, a first duration of the first nitrogen filling concentration, a second nitrogen filling concentration to be achieved in the second wrapping layer, and a second duration of the second nitrogen filling concentration. The size of the target frame, the size of the first wrapping layer, and the size of the second wrapping layer are determined based on the size of the tobacco cigarette machine to be filled with nitrogen. The tobacco cigarette machine is wrapped with the first wrapping layer. The target frame is surrounded by the tobacco cigarette machine wrapped with the first wrapping layer. The first wrapping layer and the second wrapping layer are wrapped with a second wrapping layer. The portions where the first wrapping layer and the second wrapping layer contact the ground are sealed with adhesive.

[0036] Exemplarily, in order to simplify the nitrogen filling device as much as possible, an exhaust pipe with a pipeline can be used, and there are two ventilation pipe openings on the pipeline, and a nitrogen generator with two nitrogen filling pipe openings is used. A ventilation pipe opening on the exhaust pipe is deeply inserted into the interior of the first package layer, and the air in the first package layer is extracted by the ventilation pipe opening. Another ventilation pipe opening on the exhaust pipe is passed into the second package layer, and the air in the second package layer is extracted by the ventilation pipe opening. A nitrogen filling pipe opening of the nitrogen generator is deeply inserted into the interior of the first package layer, and when the nitrogen generator is in working condition, the area wrapped by the first package layer is filled with nitrogen. Another nitrogen filling pipe opening of the nitrogen generator is deeply inserted into the second package layer, and when the nitrogen generator is in working condition, the area wrapped by the second package layer is filled with nitrogen, so that the tobacco cigarette making machine is in a nitrogen environment. When the nitrogen concentration in the first wrapping layer reaches the first nitrogen filling concentration, the first nitrogen filling concentration is maintained for a first duration; when the nitrogen concentration in the second wrapping layer reaches the second nitrogen filling concentration, the second nitrogen concentration is maintained for a second duration to complete the nitrogen filling plan, achieve effective pest control, and improve the tobacco insect pest control effect. In addition, regional nitrogen filling pest control is adopted, and the areas are reasonably divided according to different insect conditions. Different nitrogen filling concentrations and filling times are adopted for different areas, which saves equipment energy consumption and improves the insecticidal effect.

[0037] The technical solution of the embodiment of the utility model is that the nitrogen filling device is applied to a tobacco cigarette making machine, and the nitrogen filling device includes: a first wrapping layer, a second wrapping layer, a nitrogen generator, an exhaust pipe and a nitrogen filling pipeline connected to the nitrogen generator; the first wrapping layer is used to wrap the tobacco cigarette making machine; the second wrapping layer is used to wrap on a target frame, and the target frame including the second wrapping layer fully surrounds the tobacco cigarette making machine; one end of the target frame is fixed to the ground to fully surround the tobacco cigarette making machine when the target frame is in a target state; thereby, the tobacco cigarette making machine and the area where the tobacco cigarette machine is located are respectively configured with wrapping layers, and accurate division of the area and equipment to be filled with nitrogen is achieved based on the wrapping layers, so that single wrapping or combined wrapping can be performed for different nitrogen filling plans. The exhaust pipe includes at least one pipeline, at least one pipeline includes at least one ventilation pipe opening, the ventilation pipe opening penetrates into the interior of the first wrapping layer and / or passes into the second wrapping layer, and is used to extract air from the first wrapping layer and / or the second wrapping layer; the nitrogen filling pipe includes at least two nitrogen filling pipe openings, the nitrogen filling pipe openings penetrate into the interior of the first wrapping layer and / or penetrate into the second wrapping layer, and are used to fill nitrogen into the area wrapped by the first wrapping layer and / or the second wrapping layer when the nitrogen generator is in working state; thereby, the exhaust pipe is used to extract air to reduce the air content in the area wrapped by the wrapping layer, and the nitrogen generator is used to fill nitrogen to increase the nitrogen content in the area wrapped by the wrapping layer, and then the exhaust pipe and the nitrogen generator are used to dynamically adjust the gas ratio in the area wrapped by the wrapping layer, realize automatic nitrogen filling in the area, and put the tobacco cigarette making machine in a nitrogen environment.

[0038] On the basis of the above technical solution, the nitrogen filling device is used to remove dust, bacteria and insects from the tobacco cigarette making machine.

[0039] Among them, the nitrogen device can use nitrogen to fill the wrapping layer to kill insects, and make full use of the normal equipment idleness caused by changes in production arrangements to carry out fixed-point disinfection, avoid large-scale shutdowns and affect normal production scheduling, and further improve disinfection accuracy and production volume.

[0040] On the basis of the above technical scheme, the target frame is an aluminum alloy frame, the frame body of the aluminum alloy frame is a fixed structure, and the frame body of the aluminum alloy frame completely surrounds the tobacco cigarette making machine; or, the frame body of the aluminum alloy frame is a folding structure, one end of which is fixed on the ground, and the frame body of the aluminum alloy frame completely surrounds the tobacco cigarette making machine by stretching the other end of the frame.

[0041] Among them, the target frame made of aluminum alloy has the advantages of corrosion resistance, high hardness, light weight and easy handling. The advantage of the target frame being a fixed structure is that the frame can be customized for each nitrogen-filled equipment to obtain a target frame suitable for each nitrogen-filled equipment. The advantage of the target frame being a folding structure is that the size of the target frame can be adjusted based on the size of the nitrogen-filled equipment, so that one target frame can be used to surround nitrogen-filled equipment of various sizes.

[0042] For example, the target frame may be formed by splicing aluminum alloy frames, and the aluminum alloy frames are fixed with locks. After assembly, the target frame is overall stable and does not shake, thus ensuring safety.

[0043] On the basis of the above technical solution, an exhaust valve is also provided on the exhaust pipe, which is connected to the negative pressure dust removal system. It is used to extract air in the area wrapped by the first wrapping layer and the second wrapping layer when the negative pressure dust removal system is in working state to control the oxygen content in the wrapping area.

[0044] The exhaust valve may refer to a control valve. The exhaust valve can change the exhaust force and the exhaust wind speed in the pipeline by adjusting the valve opening. The negative pressure dust removal system may refer to a system that uses the negative pressure principle to remove dust and exhaust air from the exhaust pipe.

[0045] Specifically, when the negative pressure dust removal system is in working state, the negative pressure dust removal system can extract the air in the area wrapped by the first wrapping layer and the second wrapping layer through the exhaust pipe. The exhaust valve on the exhaust pipe can control the exhaust force by adjusting the valve opening, so as to achieve the purpose of controlling the oxygen content in the wrapped area, and then personalized valve opening can be used for different areas to adjust the oxygen content in the wrapped area in a personalized manner.

[0046] On the basis of the above technical solution, the exhaust pipe includes a first regulating valve corresponding to the area wrapped by the first wrapping layer, and a second regulating valve in the area wrapped by the second wrapping layer. The first regulating valve and the second regulating valve are used to adjust the exhaust volume in the corresponding wrapping area; the nitrogen filling pipeline includes a third regulating valve in the area wrapped by the first wrapping layer, and a fourth regulating valve in the area wrapped by the second wrapping layer. The third regulating valve and the fourth regulating valve are used to adjust the nitrogen filling volume in the corresponding wrapping area.

[0047] The first regulating valve is used to adjust the amount of air extracted in the area wrapped by the first wrapping layer. The third regulating valve is used to adjust the amount of nitrogen filled in the area wrapped by the first wrapping layer. The second regulating valve is used to adjust the amount of air extracted in the area wrapped by the second wrapping layer. The fourth regulating valve is used to adjust the amount of nitrogen filled in the area wrapped by the second wrapping layer. The advantage of this arrangement is that the amount of air extracted and the amount of nitrogen filled in each wrapping area can be adjusted independently, and the gas concentration in each wrapping area can also be adjusted independently, further improving the control accuracy of the gas concentration in each area, thereby achieving precise nitrogen filling.

[0048] On the basis of the above technical solution, the first wrapping layer and the second wrapping layer are made of film materials with sealing properties. The advantage of this arrangement is that the film materials with strong sealing properties can be used to enhance the sealing properties of the first wrapping layer and the second wrapping layer, reduce nitrogen leakage loss, and further reduce the scope of the cordon set around the second wrapping layer, reduce the floor space occupied by the nitrogen filling equipment, or, while the scope of the cordon set around the second wrapping layer remains unchanged, further ensure the safety of personnel outside the cordon.

This embodiment further refines the tobacco cigarette making machine based on the above embodiments. The explanations of the terms that are the same or corresponding to the above embodiments are not repeated here. Figure 2 As shown, the device is applied to a tobacco cigarette making machine, and the device includes: a first wrapping layer, a second wrapping layer, a nitrogen generator, an exhaust pipe, and a nitrogen filling pipe connected to the nitrogen generator; the tobacco cigarette making machine includes a packaging machine and a rolling machine, the packaging machine and the rolling machine are connected, the first wrapping layer includes at least two, used to seal the rolling machine and the packaging machine, one of the first wrapping layers is used to seal the rolling machine, and the other first wrapping layer is used to seal the packaging machine.

[0051] Among them, the second wrapping layer is used to wrap around the target frame, and the target frame including the second wrapping layer fully surrounds the tobacco cigarette making machine; the target frame is fixed on the ground at one end to fully surround the tobacco cigarette making machine when the target frame is in the target state; the exhaust pipe includes at least one pipeline, and at least one pipeline includes at least one ventilation pipe opening, which penetrates into the interior of the first wrapping layer and / or passes into the second wrapping layer, and is used to extract air in the first wrapping layer and / or the second wrapping layer; the nitrogen filling pipeline includes at least two nitrogen filling pipe openings, which penetrate into the interior of the first wrapping layer and / or into the second wrapping layer, and are used to fill the area wrapped by the first wrapping layer and / or the second wrapping layer with nitrogen when the nitrogen generator is in working state; the nitrogen generator is used to fill the area wrapped by the first wrapping layer and the second wrapping layer with nitrogen, so that the tobacco cigarette making machine is in a nitrogen environment.

[0052] According to the technical solution of the embodiment of the utility model, the tobacco cigarette-making machine includes a packaging machine and a rolling machine, the packaging machine and the rolling machine are in a connected state, the first wrapping layer includes at least two, for sealing the rolling machine and the packaging machine, one of the first wrapping layers is used to seal the rolling machine, and the other first wrapping layer is used to seal the packaging machine, thereby refining the tobacco cigarette-making machine, and adopting a more refined regional nitrogen filling insecticide for the refined equipment, reasonably dividing the areas according to different insect conditions, adopting different nitrogen filling concentrations and nitrogen filling times for different areas, further saving equipment energy consumption, and carrying out targeted nitrogen filling to improve the insecticidal effect.

[0053] On the basis of the above technical solution, an oxygen content detection device is also provided on the outer wall of the packaging machine and the coiling machine, and the oxygen content detection device is used to detect the oxygen content of the packaging machine and the coiling machine in a sealed state. The advantage of such a setting is that the oxygen content in the area wrapped by each wrapping layer can be measured in real time, and the accuracy of nitrogen filling in the area can be further improved.

[0054] Based on the above technical solution, the device also includes a central control console; the central control console is used to receive the oxygen content and, when it is determined that the oxygen content is higher than a preset content threshold, generate a control signal and send it to the nitrogen generator, the pipeline valve of the nitrogen filling pipeline connected to the nitrogen generator, and the exhaust valve corresponding to the exhaust pipe.

[0055] The oxygen content may refer to the oxygen content in the area detected by the oxygen content detection device. The preset content threshold may refer to the minimum oxygen content value at which tobacco insects can survive. The control signal is used to increase the nitrogen filling amount and the air extraction amount.

[0056] Exemplarily, the oxygen content detection device can also detect in real time the oxygen content of the packaging machine and the rolling machine in a sealed state, as well as the oxygen content in the area wrapped by the second wrapping layer. The central control console monitors the oxygen content of each device and area, and compares it with the preset content threshold of each corresponding device and the preset content threshold of each corresponding area. When it is determined that the oxygen content is higher than the preset content threshold, a control signal is generated and sent to the nitrogen generator, the pipeline valve of the nitrogen filling pipeline connected to the nitrogen generator, and the exhaust valve corresponding to the exhaust pipe. The nitrogen generator enters the working state based on the control signal. Increase the opening difference between the pipeline valve and the exhaust valve so that the nitrogen filling amount is greater than the air extraction amount, and realize automatic nitrogen replenishment, thereby reducing the oxygen content to below the preset content threshold, and ensuring that the oxygen content continues to be stable below the preset content threshold, ensuring the nitrogen filling effect, and improving the insecticidal effect.

[0057] On the basis of the above technical solution, the central control console communicates with the nitrogen generator and the negative pressure dust removal system respectively, and is used to send a control signal to the nitrogen generator and / or the negative pressure dust removal system based on the received oxygen content, so that the negative pressure dust removal system and / or the nitrogen generator can work. The advantage of such a setting is that the central control console can send a control signal to the nitrogen generator and / or the negative pressure dust removal system that needs to be operated based on the comparison result of the oxygen content, so that the negative pressure dust removal system and / or the nitrogen generator can work, thereby realizing automatic control of the nitrogen generator and / or the negative pressure dust removal system based on the oxygen content.

[0059] Among them, following the above example, the first preset value can be the first nitrogen filling concentration in the nitrogen filling plan, the first duration can be the first duration in the nitrogen filling plan, the second preset value can be the second nitrogen filling concentration in the nitrogen filling plan, and the second duration can be the second duration in the nitrogen filling plan.

Area C does not include areas A and B in the area. The insect situation in area A is more serious than that in area B, and insect control is more difficult. The insect situation in area B is more serious than that in area C. In combination with the insect situation in each area, the exhaust duct and nitrogen filling pipeline in the nitrogen filling equipment are connected to the area. A cordon is set up around area C for safety protection. Nitrogen is filled in area A to reduce the oxygen concentration to (K-K2)%, and the duration is N+N2 days. Nitrogen is filled in area B to reduce the oxygen concentration to (K-K1)%, and the duration is N+N1 days. Nitrogen is filled in area C to reduce the oxygen concentration to K%, and the duration is N days. The oxygen content in each area is detected by an oxygen content detection device, and nitrogen is supplemented at any time. For example, when the oxygen content detected in area A is higher than (K-K2)%, the central console generates a signal for nitrogen supplementation in area A and sends it to the corresponding equipment for nitrogen supplementation. After disinfection is completed, the nitrogen filling equipment can be disassembled quickly and conveniently.
