Description

Production site structure for solving counter-flow of spinning and winding airflow

Technical Field

The utility model belongs to the technical field of the chemical fiber production technique and specifically relates to a solve place structure is used in production of spinning and coiling air current countercurrent.

Background

Spinning and winding are indispensable production procedures in the chemical fiber production industry, and normal production can be carried out only in an environment with relatively balanced air pressure. Under the condition of normal air pressure balance, the tows enter a winding floor of a first floor from a spinning floor of a second floor through a passage. The air pressure of the spinning floor is higher than that of the winding floor because the temperature of the spinning floor is higher than that of the winding floor. Therefore, the jitter of the tows is increased and the broken ends are increased from the production process point of view. In order to meet the requirement of air pressure balance, a plurality of fans are designed to continuously perform air draft on the winding floor to reduce the pressure, so that the enterprise cost is increased. This situation is wasteful from the equipment configuration point of view and is not in accordance with the principle of resource saving.

The spinning channel is used as an important device for stably shaping the tows and plays an important role in the production of chemical fibers. The spinneret plate discharges tows, the tows are stretched, after cooling and oiling, the tows enter a channel opening to be stably shaped, in order to shape the tows in a stable environment, the tows preferably are in a state of no wind and no shaking after entering the channel opening, but because the temperature between a spinning floor and a winding floor is different in a normal production process, the pressure difference of the floor is caused, the air pressure of the winding floor is larger than that of the spinning floor, a return air phenomenon can be generated, or a large amount of cold air is blown into the channel opening, so that the tows shake greatly at the channel opening, and the heat loss of the spinning floor is large. The bundle shaking is large, so that the field bundle broken ends are more, the production is unstable, impurities such as broken yarn particles easily fall into the channel and are difficult to clean, and the environmental sanitation is influenced. Therefore, to reduce the positive air pressure from the winding floor to the spinning floor, it is preferable that the spinning floor generates a slight positive pressure to the winding floor.

At present, most of the methods for eliminating the winding wind pressure use a fan. The range of pressure discharge by using the fan is small, the whole production site structure cannot be covered, and the defect of unbalanced air pressure exists. And the continuous use of the fan can also lead to the waste of production energy, can cause the pollution to the environment and increase the production cost of the electric charge. The power of 30 kilowatt of one air returning machine is used at 70%, and the power consumption of one factory is calculated according to the ratio of 11 air returning machines, and the power consumption per year is 30 × 24 × 0.7 × 11 × 365 × 0.63 and is approximately equal to 127.5 ten thousand yuan.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the not enough of above-mentioned technique and providing a solve spinning and production site ground structure against current of coiling air current, the atmospheric pressure that can effectively reduce the coiling floor makes coiling floor and spinning floor atmospheric pressure basic balance.

In order to achieve the purpose, the utility model relates to a solve spinning and production site structure against current of coiling air current, the site structure includes auxiliary assembly floor, fuse-element pipeline floor, spinning floor and coiling floor, and by supreme coiling floor, spinning floor, fuse-element pipeline floor and the auxiliary assembly floor of being in proper order down, be provided with a plurality of tuber pipes at the top of coiling floor, the tuber pipe upwards extends to fuse-element pipeline floor or auxiliary assembly floor or place structure outside, does not communicate between tuber pipe and the spinning floor.

The field structure is a production workshop, and the general production workshop has at least four layers, wherein auxiliary equipment floors are used for installing auxiliary equipment such as a heat medium circulating system, an air conditioning unit and the like; the melt pipeline floor is a spinning assembly used for installing melt conveying pipelines, metering pumps and other equipment and quantitatively conveying the melt to the spinning floor; the spinning floor is used for mounting spinning equipment, the winding floor is used for winding and packaging shaped chemical fiber filaments, the spinning floor is communicated with the winding floor through a channel, and the chemical fiber filaments penetrate through the channel. The temperature of the spinning floor and the winding floor is relatively high, the spinning floor is provided with heat emitted by the box body and the biphenyl heat medium pipeline after the spinning, the winding floor is provided with heat emitted by equipment, and under the basic condition, the temperature of the spinning floor is 33 ℃, and the temperature of the winding floor is 30 ℃. The temperature of the spinning floor is relatively high, so the air pressure is relatively low, air flow in the channel is conveyed from the winding floor to the spinning floor, and the filament direction of the spinning process is from the spinning floor to the winding floor through the channel. The two have conflict in direction, when the airflow from the winding floor to the spinning floor is large, the tows can fly, shake and even break, and the production is seriously influenced. In the above scheme, the upper end of the winding floor is provided with the air pipe, the air pipe upwards extends to the outside of a production workshop or other floors except a spinning floor, and air flow in the winding workshop can be conveyed to the outside of the production workshop or other floors so as to reduce air pressure in the winding workshop, so that the air pressure of the winding floor and the air pressure of the spinning floor tend to be balanced or the air pressure of the spinning floor is slightly larger than the air pressure of the winding floor, and the stability of conveying tows in a channel is ensured.

The specific principle is as follows: when the closed container has a heat source, the pressure of the closed container is naturally increased. The situation is different for the atmosphere, and when the atmospheric temperature in a certain area is increased due to a certain factor, the expansion of the air volume is caused, and the air molecular potential is necessarily diffused to the surrounding area. At high temperatures, the gas molecules will move faster than they are, which will be the factor that promotes the pressure increase. On the other hand, as the temperature increases, gas molecules diffuse to the surroundings, and the number of gas molecules in this region decreases, thereby forming a factor that promotes the pressure decrease. The actual situation is the result of the two opposing factors acting together. As to which of these two factors plays a major role, diffusion plays a major, decisive role in both temperature changes and molecular diffusion in non-enclosed spaces. The kinetic energy among gas molecules can be increased continuously in the closed space as long as the air is heated continuously. Resulting in a continuous increase in gas pressure. In our production workshop, the spinning floor is in a high-temperature state relative to the winding floor because of being in a semi-sealed state. In the actual production process, the diffusion effect of air is obviously larger than the air pressure change caused by the temperature change effect. Therefore, the gas pressure of the spinning floor is lower than that of the winding floor in the diffusion process, so that the gas pressure of the winding floor tends to rise in the shaft.

And among this application technical scheme, through the design of tuber pipe, and the quantity of tuber pipe and the sectional area of tuber pipe can arrange the design according to actual conditions, the design of tuber pipe can be under the condition of the equipment safety of not influencing the spinning floor, the fuse-element pipeline floor, the auxiliary assembly floor and evenly arrange as far as under the condition of workshop intensity, reduce the local air current flow of winding floor, and can all discharge the atmospheric pressure of winding floor to the external world through the tuber pipe, avoid producing the condition of reverse flow in the corridor, promote the stability of spinning process.

As optimization, the air pipe is vertically upwards arranged and extends to the top of the site structure. It is outside in order to let the air current of coiling the floor more smooth and easy carry to place structure through the tuber pipe, so the step-down effect to the coiling floor is more obvious.

And optimally, an air volume control valve is arranged on the air pipe. The air pressure of the floor is not influenced by the arrangement of the air pipes, so that the regional balance between the air pressure of the winding floor and the air pressure of the spinning floor can be realized or the air pressure of the spinning floor is slightly higher than the air pressure of the winding floor by controlling the air pressure of the winding floor, the air flow in a channel is ensured to be in the same direction with the filament bundles, and the filament bundle production is more stable and reliable.

Preferably, the size of the air duct can be a rectangular structure of 100 × 80 cm. When the hole is smaller than 100X 80cm, the air on the winding floor is not easy to be discharged out of the production workshop, and the air pressure is 1043.4hpa to 1027.0 hpa. When the hole is larger than 100 multiplied by 80cm, the air pressure of the winding floor is low, the wind speed at the shaft opening is 2.7 meters per second, and the wind speed is too high, so that the end breakage is easily caused, and the production is unstable. The hot air is naturally discharged through the pipeline, the indoor environment temperature is reduced, the environment fan frequency can be reduced, and the effects of energy conservation and consumption reduction are achieved. Before this system is not used, the hot air is extracted from the chamber by the return fan, which in contrast corresponds to a reduction in the use of 12 return fans, typically at a frequency of 25hz, so that the energy consumption per day is reduced by 25 x 12 x 24=7200 hz. Compared with the reduction of the energy consumption, the energy consumption of reducing the frequency of the environmental fan by 1-2hz is very small. The winding floor after partial hot gas is discharged is negative pressure relative to the spinning floor, and the airflow of the spinning floor can flow towards the winding floor, so that the airflow and the filament bundle are in the same direction, the phenomenon of end breakage is reduced, the waste filament output is reduced, and the yield of finished products is increased.

And a fire-proof valve is arranged in the air pipe within the range of the spinning floor. The setting of fire prevention valve can be in case under the condition of taking place the conflagration, avoid the intensity of a fire to stretch to other floors from the tuber pipe in, so its security is better.

The utility model discloses a rain canopy is used for the tuber pipe tip to shelter from the rainwater, and the shrouding is used for opening and closes the tip buckle of tuber pipe, and the canopy is used for sheltering from the rainwater for the tuber pipe tip. Due to the fact that the temperature changes greatly due to different seasons and weather, part of the air pipes are occasionally stopped, and the outlet can be sealed through the sealing plate in order to prevent sundries from entering.

The air volume adjusting valve can be an electromagnetic valve, sensors for detecting air pressure are respectively arranged in the winding floor and the spinning floor, and the opening degree of the electromagnetic valve is controlled according to the pressure comparison detected by the sensors so as to ensure the air pressure balance between the winding floor and the spinning floor.

The utility model provides a solve production site structure against current of spinning and coiling air current and use, discharge the air current of coiling the floor to the outside site structure through the tuber pipe for the atmospheric pressure of coiling floor and the atmospheric pressure regional balance of spinning floor or coiling floor is less than the atmospheric pressure of spinning floor a little, ensures that the silk bundle is stably carried in the corridor, promotes the silk bundle quality, reduces the condition such as broken end.
