Description

Technical Field

[0001] The utility model relates to the technical field of ventilation, in particular to a ventilation structure for a factory. Background Art

[0002] In the production process of preparing lecithin, the cooling of the production space is crucial for ensuring process stability and product quality.

[0003] Currently, the production space mainly relies on natural cooling to maintain an appropriate temperature. However, with the changes in the production method and the increase in production volume in the explosion-proof area, the original natural cooling method can no longer meet the higher cooling requirements. Especially in the case of limited space and explosion-proof requirements, traditional cooling devices are difficult to install and use in the production space. Summary of the Utility Model

[0004] The utility model aims to provide a ventilation structure for a factory, which can effectively improve the cooling effect in the explosion-proof area without increasing the space burden of the explosion-proof area and meeting the explosion-proof requirements, and ensure the safety and stability of the production environment.

[0005] The basic solution provided by the utility model is: a ventilation structure for a factory, including an air conditioner, a fixing ring, and a main pipeline; the air conditioner is installed outside the explosion-proof area; one end of the fixing ring is connected to the air outlet of the air conditioner, and the other end is connected to the main pipeline; at least two groups of branch pipelines are connected to the main pipeline in a communicating manner; an air supply port is connected to the end of the branch pipeline far away from the main pipeline; the main pipeline is laid above the workshop steel platform, and the branch pipeline is laid from above the workshop steel platform through the top of the explosion-proof door pocket to the explosion-proof area, and the air supply port is located above the fixed operation position in the explosion-proof area, so that each group of branch pipelines corresponds to a fixed operation position; the air supply port is provided with a switch for controlling the air outlet and a plurality of louvers for adjusting the wind direction.

[0006] The working principle and advantages of the utility model are as follows: cold air enters the explosion-proof area from the air outlet of the air conditioner through the main pipeline and the branch pipeline, and exits at the fixed operation position in the explosion-proof area, realizing the air supply and cooling of the explosion-proof area.

[0007] Compared with the prior art, in view of the space limitation and explosion-proof requirements in the explosion-proof area, an out-of-area cooling solution is specifically proposed. Cold air is sent from outside the explosion-proof area, through the steel platform in the workshop, into the explosion-proof area; the entire ventilation structure is set outside the explosion-proof area, and only the air supply outlet and some branch pipes enter the explosion-proof area. The pipes can pass through the wall at the top of the explosion-proof door pocket to enter the explosion-proof area, and only drill holes at the top of the explosion-proof door pocket to complete the pipeline layout, minimizing the installation and transformation of the explosion-proof area as much as possible. There are no other ventilation equipment installed and operating in the explosion-proof area. The change in the operating state of the ventilation structure will not cause any impact on the normal operation of the production equipment in the explosion-proof area except for briefly affecting the cooling effect in the explosion-proof area. On the premise of not affecting the normal operation of the explosion-proof area, this solution structure maximally meets the operation safety, explosion-proof requirements and cooling needs of the explosion-proof area at the same time.

[0008] The structure components of this solution are simple, easy to maintain and replace, which can greatly reduce the device cost and maintenance cost; the structure is reasonable, with a high degree of fit with the installation gap in the explosion-proof area, facilitating the installation of the air supply outlet and branch pipes and efficient air supply. The on-site pipeline layout method is simple, and the overall occupied space is small after installation, without interfering with the entry and exit of personnel and normal production; the explosion-proof performance and installation method of the structure components can meet the explosion-proof requirements; the overall layout of the structure can effectively improve the cooling effect without increasing the space burden of the explosion-proof area, ensuring the safety and stability of the production environment.

[0014] The following is a more detailed description through specific embodiments:

[0015] The reference signs in the attached drawings of the specification include: air conditioner 1, air conditioner air outlet 11, fixing ring 2, connecting pipe 3, air supply outlet 4, first side 41, second side 42, flow equalizing plate 43, through hole 431, louver 44, switch 45.

[0016] Embodiment 1

[0017] Basically as shown in the attached Figure 1 , Figure 2 and Figure 3 shown: The ventilation structure for a factory includes an air conditioner 1, and the air conditioner 1 is installed outside the explosion-proof area. Specifically, the air conditioner 1 is mobile. The mobile air conditioner 1 does not require additional installation, reducing the risk of explosion caused by installation operations near the explosion-proof area, and improving safety from the installation aspect; the price of an ordinary air conditioner is much lower than that of an explosion-proof air conditioner. Based on an ordinary air conditioner, with the settings of installation outside the area and being mobile, the explosion-proof requirements can be met, and professional explosion-proof air conditioners do not need to be used, thus reducing costs while meeting the explosion-proof requirements.

[0018] It further includes a fixing ring 2. One end of the fixing ring is connected to the air conditioner air outlet 11, and the other end is connected to the main pipeline 3. Specifically, the fixing ring 2 serves to seal and detachably connect the air conditioner air outlet 11 and the main pipeline 3. The sealed connection ensures that the cold air blown out from the air conditioner air outlet 11 efficiently enters the main pipeline 3, and the detachable connection ensures convenient and safe installation without the need for additional electrically charged equipment for installation operations, reducing the risk of explosion caused by installation and also improving safety from the installation aspect.

[0019] The main pipeline 3 is communicatively provided with at least two groups of branch pipelines; one end of the branch pipeline far from the main pipeline 3 is connected with an air supply outlet.

[0020] Specifically, both the main pipeline 3 and the branch pipelines are made of explosion-proof materials to meet the on-site explosion-proof requirements. The diameter of the main pipeline is larger than that of the branch pipelines, and the diameter of the branch pipelines is adapted to the gap in the explosion-proof area. The entire pipeline is reasonably laid out and the diameter and length are selected according to the on-site situation. Due to the limited space and explosion-proof requirements in the explosion-proof area, in this solution, the main pipeline is laid above the workshop steel platform, and the branch pipelines are laid from above the workshop steel platform through the gap in the explosion-proof area to the explosion-proof area. The air supply outlets are located above the fixed operation positions in the explosion-proof area, so that each group of branch pipelines corresponds to a fixed operation position; this way makes clever use of the gap in the explosion-proof area that can connect the workshop steel platform without any installation transformation of the explosion-proof area, reducing the risk of explosion caused by construction. The pipeline is laid from the steel platform to the explosion-proof area, and the entire pipeline is located at the top of the workshop. The air supply outlets reach the fixed operation positions directly, ensuring the air supply efficiency and minimizing the floor area as much as possible without interfering with the entry and exit of personnel and normal production, which is the most favorable layout method that can be actually applied.

[0021] The branch pipeline includes a connected first branch pipeline 31 and a second branch pipeline 32. One end of the first branch pipeline 31 far from the second branch pipeline 32 is connected to the main pipeline 3, and one end of the second branch pipeline 32 far from the first branch pipeline 31 is connected to the air supply outlet 4. The first branch pipeline 31 and the second branch pipeline 32 are vertically arranged. This branch pipeline method meets the requirements of the actual space layout and is conducive to guiding the air flow.

[0022] The structure of the air supply outlet 4 is a rectangular flat structure. An air outlet opening is formed on the first side 41 of the air supply outlet 4, and an air inlet opening is formed on the second side 42. The air inlet opening is connected to the branch pipeline. Among them, the first side 41 and the second side 42 are parallel, and the air inlet opening is located in the middle of the second side 42, which is conducive to guiding the air flow. The air supply outlet 4 is provided with a switch 45 for controlling the air outlet and a plurality of louvers 44 for adjusting the air direction. The louvers 44 are installed at the air outlet opening. The position of the air supply outlet 4 can be 1 - 1.5 m above the fixed operation position, with a suitable height, facilitating the staff at the fixed operation position to adjust the air outlet.

[0023] During actual use, the air conditioner 1 is placed at a suitable position outside the explosion-proof area. The fixing ring 2 stably seals and detachably connects the air outlet 11 of the air conditioner and the main pipeline 3. The main pipeline 2 and the branch pipeline are laid above the workshop steel platform. Part of the branch pipeline and the air supply outlet enter the explosion-proof area. The overall layout is reasonable, without interfering with normal production work, occupying a small area, and having an obvious cooling effect. As Figure 1 shown by the arrow, the cold air passes through the main pipeline 3 from the air outlet 11 of the air conditioner, enters the interior of the air supply outlet 4 through the air inlet opening on the second side 42 of the air supply outlet 4, and then enters the explosion-proof area through the air outlet opening on the first side 41 of the air supply outlet 4, realizing air supply and cooling for the explosion-proof area.

[0024] The ventilation structure for the factory provided in this embodiment, considering the limitations of the production space and explosion-proof requirements, proposes a cooling supply scheme outside the area, and conducts targeted structural optimization. The cold air is sent into the explosion-proof area from outside the explosion-proof area, through the workshop steel platform and the top of the explosion-proof door pocket. The air conditioner is placed outside the explosion-proof area, and the pipeline is laid from the workshop steel platform through the installation hole at the top of the explosion-proof door pocket to the explosion-proof area. It can be installed and operated without stopping work and with minimal installation modification to the explosion-proof area, achieving the effect of efficiently reducing the temperature in the explosion-proof area. At the same time, through the detachable installation of the components, the construction and installation use of live equipment are minimized as much as possible, reducing the risk of explosion caused by electric sparks and improving the installation safety. Only part of the pipeline and the air supply outlet of the entire structure are located in the explosion-proof area, and the air conditioner and most of the pipeline are located outside the explosion-proof area, minimizing the space occupation in the explosion-proof area as much as possible, and not additionally setting live equipment to operate in the explosion-proof area, improving the operation safety. This ventilation structure scheme, whether it is the components themselves, or the installation and operation processes, all meet the operation safety, explosion-proof requirements and cooling needs of the explosion-proof area to the greatest extent, and is suitable for the existing production workshop layout.

[0025] Example Two

[0026] Different from Example One, the air supply opening 4 and the branch pipe can be detachably connected by threads. Since the air supply opening is inside the explosion-proof area, considering the explosion-proof requirements, the threaded detachable connection method is adopted, which can reduce the construction and installation of live equipment here and reduce the explosion risk caused by construction.

[0027] The air supply opening 4 and the branch pipe can also be connected by a rotatable structure. The rotatable structure is realized by using existing technologies. On the basis of adjusting the wind direction of the louver, the adjustable direction is added to realize the multi-directional adjustment of the air supply opening 4, which is more conducive to the requirements of different workers for the air outlet direction.

[0028] Example Three

[0029] Different from Example One, as Figure 4 shown, the top surface of the air supply opening 4 has an inclined angle, which gradually decreases along the air outlet direction (shown by the arrow in the figure). The inclined angle ɑ can be 3-7 degrees, and the angle range is adapted to the height of the gap. The inclined design can achieve the effect of wind gathering, increasing the speed of the air outlet, avoiding the accumulation of impurities such as dust at the air outlet, and improving the air supply efficiency.

[0030] Example Four

[0031] Different from Example One, as Figure 5 shown, a flow equalizing plate 43 with a number of through holes 431 is provided near the air inlet opening inside the air supply opening 4. The flow equalizing plate 43 is arranged parallel to the air outlet opening of the air supply opening 4 for uniform air outlet; the number of through holes 431 is evenly distributed, and the diameter of the through holes 431 gradually increases from the middle to both sides (shown by the arrow in the figure), so that the gas sent from the branch pipe is evenly distributed inside the air supply opening 4, improving the distribution of the air flow field at the air outlet entering the explosion-proof area. The air volume at each place can be further adjusted through the louver 44, further strengthening the air outlet uniformity of the air supply opening 4.

[0032] The above are only the embodiments of the present utility model. Specific structures and common knowledge such as characteristics that are well-known in the art are not described in detail herein. Those of ordinary skill in the art know all the common general technical knowledge in the technical field to which the utility model belongs before the filing date or the priority date, can know all the prior art in this field, and have the ability to apply the conventional experimental means before this date. Those of ordinary skill in the art can, under the inspiration given in this application, combine their own abilities to complete and implement this solution. Some typical well-known structures or well-known methods should not become obstacles for those of ordinary skill in the art to implement this application. It should be noted that for those skilled in the art, without departing from the structure of the present utility model, several deformations and improvements can still be made, and these should also be regarded as the protection scope of the present utility model, and these will not affect the implementation effect of the present utility model and the practicality of the patent.
