Description

Technical Field

[0001] This utility model relates to the field of shrimp oil production, specifically a ventilation device for a shrimp oil production workshop. Background Technology

[0002] Shrimp oil production workshops are used to process shrimp oil. Because shrimp itself has a fishy smell, this smell can easily spread into the workshop during the shrimp crushing and shrimp oil extraction process, affecting the workshop environment. Therefore, ventilation and deodorization treatments are often required in shrimp oil production workshops. Different production workshops have different temperatures and humidity levels. For example, workshops where shrimp oil is extracted often have liquid pools, resulting in high air humidity. After prolonged ventilation, the activated carbon used for deodorization easily becomes damp, reducing its odor adsorption effect and requiring frequent replacement. This significantly increases the frequency of maintenance and repair of the ventilation system, and the replacement of activated carbon is quite complicated, making the use of ventilation systems in workshops with high humidity quite inconvenient. Utility Model Content

[0003] The purpose of this utility model is to provide a ventilation device for shrimp oil production workshops. It can solve the technical problem that ventilation devices in workshops with high humidity are prone to moisture absorption, which affects the deodorization effect and requires frequent replacement. It heats and dehumidifies activated carbon, reducing the situation where activated carbon is affected by moisture and thus reducing the frequency of replacement, simplifying the replacement steps of activated carbon, and improving the convenience of later inspection and maintenance of the ventilation device.

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] A ventilation device for a shrimp oil production workshop includes an air inlet pipe connected to multiple production workshops. Multiple branch pipes are connected to the air inlet pipe, each branch pipe connected to one side of a production workshop. An air outlet pipe is connected to the other side of the production workshop. An installation cylinder is connected to the end of the air outlet pipe, with one end of the installation cylinder extending into the interior of the air outlet pipe. The end of the installation cylinder located inside the air outlet pipe is closed. A filter cylinder is movably connected inside the installation cylinder. Multiple air outlet holes are provided at corresponding positions on the sidewalls of the installation cylinder and the filter cylinder. The interior of the filter cylinder is filled with activated carbon. Multiple exhaust holes are provided at the end of the filter cylinder located outside the air outlet pipe. A heating pipe for heating the activated carbon is provided inside the air outlet pipe.

[0006] Furthermore, one end of the filter cylinder is threadedly connected to the end of the mounting cylinder located inside the air outlet pipe, and the other end of the filter cylinder is provided with a limiting ring.

[0007] Furthermore, the limiting ring is provided with a sealing ring, which is used to seal the gap between the filter cylinder and the mounting cylinder.

[0008] Furthermore, the air intake pipe is provided with a communicating air intake shell, the side wall of the air intake shell is provided with a plurality of side air intake holes, and an inner sleeve for controlling the opening and closing of the side air intake holes is rotatably connected inside the air intake shell.

[0009] Furthermore, the inner sleeve is also provided with multiple side air inlets on its side wall, and the side air inlets on the inner sleeve and the air inlet shell are aligned when the inner sleeve rotates.

[0010] Furthermore, the bottom of the air intake housing is provided with a lower air intake hole, and the inner sleeve is used to control the opening and closing of the lower air intake hole. When the side air intake hole is closed, the lower air intake hole is open.

[0011] Furthermore, the bottom of the inner sleeve is also provided with a lower air inlet hole, and when the inner sleeve rotates, the lower air inlet hole on the inner sleeve and the air inlet shell are aligned.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The structure of this utility model includes an air inlet pipe, on which multiple branch pipes connected to the production workshop are provided. The branch pipes are connected to one side of the production workshop, and an air outlet pipe is provided on the other side of the production workshop. This structure enables multiple production workshops to implement a unified air intake and separate air outlet, so that there is no airflow exchange between multiple production workshops during ventilation, reducing mutual interference on the temperature and humidity of different workshops, and improving the smoothness and efficiency of ventilation.

[0014] 2. An installation cylinder is installed at the end of the air outlet pipe, located inside the air outlet pipe. A filter cylinder is movably connected inside the installation cylinder, and the filter cylinder is filled with activated carbon. Multiple air outlet holes are provided at corresponding positions on the side walls of the installation cylinder and the filter cylinder. A heating tube for heating the activated carbon is installed inside the air outlet pipe. This structure can heat the activated carbon using the heating tube to expel the moisture adhering to the activated carbon in the filter cylinder, ensuring the adsorption effect of the activated carbon and reducing the frequency of activated carbon replacement. On the other hand, when replacing, the filter cylinder only needs to be removed from the installation cylinder, making the replacement of activated carbon simpler and more convenient. This greatly reduces the frequency and difficulty of later maintenance of the ventilation device and improves the convenience of actual use. Attached Figure Description

[0023] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0024] Reference Figure 1 and Figure 2This utility model describes a ventilation device for a shrimp oil production workshop 1. The main structure includes an air inlet pipe 2 connected to multiple production workshops 1. An air intake fan is installed on the air inlet pipe 2 to introduce outside air into the multiple production workshops 1, thereby replacing the fishy-smelling air inside the production workshops 1 and achieving ventilation. Preferably, a filter screen is installed inside the air inlet pipe 2 to filter dust and other impurities in the air, ensuring the cleanliness of the air entering the production workshops 1. Multiple branch pipes 3 are connected to the air inlet pipe 2, each branch pipe 3 connected to one side of a production workshop 1. This structure allows outside air to enter the air inlet pipe 2 and then enter each production workshop 1 through the multiple branch pipes 3, maintaining a clean environment in the multiple production workshops 1. A standardized air intake operation simplifies the complexity of the ventilation system and improves air intake efficiency. An exhaust pipe 4 is connected to the other side of production workshop 1, and an exhaust fan is installed on the exhaust pipe 4 to expel odorous air from the workshop. Each production workshop 1 has a separate exhaust pipe 4, enabling independent ventilation within multiple production workshops 1. There is no airflow exchange of odorous air between multiple production workshops 1, reducing interference with workshop temperature and humidity and ensuring smooth and efficient ventilation. An installation cylinder 5 is connected to the end of the exhaust pipe 4. The diameter of the installation cylinder 5 is smaller than that of the exhaust pipe 4, and one end of the installation cylinder 5 is fixed to the end of the exhaust pipe 4 by welding or integral molding. One end of the installation cylinder 5 extends into the interior of the exhaust pipe 4. The end of the cylinder 5 located inside the exhaust pipe 4 is sealed. This structure prevents the exhaust air from being directly discharged from the exhaust pipe 4; instead, it must pass through the cylinder 5 before being discharged. A filter cylinder 6 is movably connected inside the installation cylinder 5. The filter cylinder 6 is used for deodorizing the exhaust air. Multiple air outlets 7 are provided at corresponding positions on the side walls of both the installation cylinder 5 and the filter cylinder 6. This structure allows the exhaust air to pass through the multiple air outlets 7 on the inner walls of the installation cylinder and the filter cylinder 6 before entering the filter cylinder 6. The filter cylinder 6 is filled with activated carbon. When the air entering the filter cylinder 6 comes into contact with the activated carbon, the odor molecules are adsorbed by the activated carbon, thereby achieving deodorization of the exhaust gas, ensuring the quality of the exhaust air, and reducing odors. Due to the influence of the external environment, the filter cylinder 6 has multiple exhaust holes 8 at the end located outside the air outlet pipe 4. The deodorized air is discharged from the exhaust holes 8 at the end of the filter cylinder 6. The air outlet pipe 4 has a heating tube 9 for heating the activated carbon. Preferably, the heating tube 9 is an electrically heated spiral tube, which is sleeved on the outside of the mounting cylinder 5 to heat the air entering the filter cylinder 6 through the exhaust holes 7. This structure, on the one hand, prevents the activated carbon from absorbing too much moisture and becoming damp due to long-term use, thus reducing its deodorization effect. The heating operation of the heating tube 9 evaporates the moisture inside the activated carbon, thereby ensuring the dryness of the activated carbon, maintaining its odor adsorption effect, and extending the service life of the activated carbon.This design reduces the frequency of later replacement and maintenance. Furthermore, the activated carbon-containing filter cartridge 6 is detachably fixed inside the mounting cylinder 5. During replacement, simply removing the filter cartridge 6 from the mounting cylinder 5 as a whole significantly reduces the difficulty of later inspection and replacement, improving the ease of use of the ventilation system.

[0025] Preferred, refer to Figure 5 and Figure 6 One end of the filter cylinder 6 is threadedly connected to the end of the mounting cylinder 5 located inside the air outlet pipe 4. Specifically, a threaded hole is provided on the closed end of the filter cylinder 6, and one end of the filter cylinder 6 is threaded into the threaded hole, making the disassembly of the filter cylinder 6 simpler and more convenient. The other end of the filter cylinder 6 is fixed with a limiting ring 10 by welding or bolts. The diameter of the limiting ring 10 is larger than the inner diameter of the mounting cylinder 5. The limiting ring 10 is used to limit the length of the filter cylinder 6 during installation, and it is also convenient to directly rotate and disassemble the limiting ring 10 during later disassembly, which improves the convenience of disassembly, assembly and use of the filter cylinder 6.

[0026] Preferably, the limiting ring 10 is provided with a sealing ring, which is used to seal the gap between the filter cylinder 6 and the mounting cylinder 5. After the filter cylinder 6 is installed, the sealing ring on the side of the limiting ring 10 seals the gap between the end of the filter cylinder 6 and the end of the mounting cylinder 5, thereby preventing air from being discharged directly without passing through the filter cylinder 6, and improving the accuracy of purifying and deodorizing the discharged air.

[0027] Preferred, refer to Figure 3 and Figure 4 The air intake pipe 2 is provided with a connected air intake shell 11. The air intake shell 11 and the air intake pipe 2 are fixedly connected by welding or integral molding. Outside air enters the air intake pipe 2 after passing through the air intake shell 11. The side wall of the air intake shell 11 is provided with multiple side air intake holes 12. The inside of the air intake shell 11 is rotatably connected by a bearing to an inner sleeve 13 for controlling the opening and closing of the side air intake holes 12. In rainy or snowy weather, the inner sleeve 13 can be rotated to close the side air intake holes 12 on the air intake shell 11, so that outside air enters the air intake shell 11 from other positions, thereby avoiding the blockage caused by outside rain and snow directly entering the air intake pipe 2 and ensuring smooth ventilation in rainy or snowy weather.

[0028] Preferably, the inner sleeve 13 is also provided with a plurality of side air inlets 12 on its side wall. When the inner sleeve 13 rotates, the side air inlets 12 on the inner sleeve 13 and the air inlet shell 11 are aligned. With this structure, the side air inlets 12 on the inner sleeve 13 can be aligned or misaligned with the side air inlets 12 on the air inlet shell 11 when the inner sleeve 13 rotates, thereby realizing the opening and closing control of the side air inlets 12. The structure is simple and the opening and closing control of the air intake is more convenient and accurate.

[0029] Preferably, the bottom of the air intake housing 11 is provided with a lower air intake hole 14, and the inner sleeve 13 is used to control the opening and closing of the lower air intake hole 14. When the side air intake hole 12 is closed, the lower air intake hole 14 is opened. This structure allows the lower air intake hole 14 at the bottom of the air intake housing 11 to open when the inner sleeve 13 rotates to close the side air intake hole 12. Thus, in rainy or snowy weather, outside air enters from the lower air intake hole 14 at the bottom, allowing outside air to enter from bottom to top. Outside rain and snow are less likely to overcome gravity and enter the air intake pipe 2, ensuring smooth air intake in rainy or snowy weather and further ensuring the smoothness of air intake in rainy or snowy weather.

[0030] Preferably, the bottom of the inner sleeve 13 is also provided with a lower air inlet 14. When the inner sleeve 13 rotates, the lower air inlet 14 on the inner sleeve 13 and the air inlet shell 11 are aligned. When the inner sleeve 13 rotates, the lower air inlet 14 at its bottom can be aligned or misaligned with the lower air inlet 14 at the bottom of the air inlet shell 11, thereby realizing the opening and closing control of the lower air inlet 14. The structure is simple, and the opening and closing control of the lower air inlet 14 is more convenient and accurate.

[0031] Working Principle: The structure of this utility model includes an air inlet pipe 2, with multiple branch pipes 3 connected to production workshop 1. Each branch pipe 3 is connected to one side of production workshop 1, and an air outlet pipe 4 is located on the other side of production workshop 1. This structure allows multiple production workshops 1 to have unified air intake and separate air outlets, thus preventing airflow exchange between the workshops during ventilation, reducing interference with temperature and humidity in different workshops, and improving ventilation smoothness and efficiency. An installation cylinder 5 is located at the end of the air outlet pipe 4, inside which a filter cylinder is movably connected. 6. The interior of the filter cartridge 6 is filled with activated carbon. Multiple air outlets 7 are provided at corresponding positions on the side walls of the mounting cylinder 5 and the filter cartridge 6. The interior of the air outlet pipe 4 is equipped with a heating pipe 9 for heating the activated carbon. This structure can heat the activated carbon using the heating pipe 9 to expel the moisture adhering to the activated carbon inside the filter cartridge 6, ensuring the adsorption effect of the activated carbon and reducing the frequency of activated carbon replacement. On the other hand, when replacing the activated carbon, it is only necessary to remove the filter cartridge 6 from the mounting cylinder 5, making the replacement of activated carbon simpler and more convenient. This greatly reduces the frequency and difficulty of later inspection and maintenance of the ventilation device and improves the convenience of actual use.
