Abstract
Description
Technical Field
[0001] This utility model relates to the field of ventilation equipment technology, and more specifically, to a special air conditioning control system for air showers. Background Technology
[0002] In clean production scenarios, before goods enter the clean area from the non-clean area, they need to be air-showered to remove dust, hair and other particles attached to their surface. At the same time, it is necessary to ensure that the temperature and humidity of the environment in which the goods are located are consistent with those of the clean area to prevent quality problems such as moisture (e.g., food goods) or condensation (e.g., electronic components) caused by temperature and humidity changes.
[0003] The existing integration of air shower equipment with air conditioning systems has significant drawbacks: the airflow diffusion range and concentration at the air conditioning outlets are fixed, making dynamic adjustment impossible based on the air conditioning output temperature. For example, when the air conditioning outputs low-temperature cold air, excessive airflow diffusion can lead to excessively low local temperatures in the air shower area, causing condensation to form on the surfaces of electronic components; conversely, when the air conditioning outputs high-temperature hot air, excessive airflow concentration can lead to excessively high local temperatures in the air shower area, causing food products to lose moisture or spoil. Furthermore, the existing equipment's airflow guiding structure is mostly a fixed design, unable to flexibly adjust the airflow direction according to the size and conveying speed of the goods, further reducing the dust removal efficiency and temperature and humidity control accuracy of the air shower. Therefore, a dedicated air conditioning control system for air showers is proposed. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a special air conditioning system for air showers, which aims to solve the problems mentioned in the background art.
[0005] This utility model provides the following technical solution: a special air conditioning regulation system for air showers, including a guide pipe installed at the air outlet of the air conditioner, and a regulation component is provided at one end of the guide pipe; The control component includes a connecting ring disposed at the end of the guide tube, a first mounting shell disposed in the middle of the connecting ring, and a second mounting shell disposed on one side of the first mounting shell. The outer side of the second mounting shell is provided with several angle-adjustable guide vanes, and each guide vane is provided with a limiting shaft at the end away from the second mounting shell. The limiting shaft abuts against the inner wall of the connecting ring and is rotatably connected to the connecting ring.
[0006] Optionally, in one possible implementation, a turntable is rotatably connected between the first mounting shell and the second mounting shell. The turntable has toothed grooves, and a plurality of gears are provided on the top. Each gear meshes with a toothed groove. One end of each of the plurality of gears passes through the second mounting shell and extends to one end of the corresponding turntable. The gears are rotatably connected to the second mounting shell. Optionally, in one possible implementation, a protective cover is provided on the side of the second mounting shell away from the first mounting shell. The protective cover is shaped like a frustum. A motor is provided in the middle of the protective cover. The output end of the motor passes through the protective cover and the second mounting shell and extends to the turntable. A crossbar is provided in the middle of the connecting ring. The first mounting shell is mounted on the crossbar by bolts. The technical effects and advantages of this utility model are as follows: By synchronously adjusting the guide vanes driven by the motor, the dynamic switching between air volume concentration and diffusion can be achieved. The airflow distribution in the air shower area can be flexibly adapted according to the air conditioner output temperature to avoid local temperature and humidity fluctuations and reduce the risk of food getting damp and electronic components condensing. The angle adjustment of the guide vanes can change the airflow speed and coverage area, and adjust the airflow direction for goods of different sizes, such as small electronic components and large food packaging, to ensure that the airflow acts evenly on the surface of the goods.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0014] A special air conditioning control system for air showers includes a guide pipe 1 installed at the air outlet of the air conditioner, and a control component is provided at one end of the guide pipe 1 to adjust the direction and diffusion range of the airflow output by the air conditioner; As attached Figure 1 Appendix Figure 3 As shown, the control component includes a connecting ring 2 located at the end of the guide pipe 1. The connecting ring 2 is a circular ring structure, and its inner diameter is adapted to the outer diameter of the guide pipe 1. It is fixed to the guide pipe 1 by welding or flange connection to ensure that the airflow can flow stably from the guide pipe 1 into the interior of the connecting ring 2. A crossbar 12 is horizontally arranged in the middle of the connecting ring 2. The two ends of the crossbar 12 are welded and fixed to the inner wall of the connecting ring 2, and a bolt hole is opened in the middle of the crossbar 12. A first mounting shell 3 is installed in the middle of the connecting ring 2 through the crossbar 12. The first mounting shell 3 is a cylindrical hollow structure, and its outer wall is detachably connected to the crossbar 12 by bolts, which facilitates later maintenance and component replacement. As attached Figure 1 Appendix Figure 4 As shown, a second mounting shell 4 is provided on one side of the first mounting shell 3. The second mounting shell 4 and the first mounting shell 3 are coaxial cylindrical structures, and the inner diameter of the second mounting shell 4 is slightly larger than the outer diameter of the first mounting shell 3. The two are rotatably connected by a bearing to ensure that the second mounting shell 4 can rotate around the axis of the first mounting shell 3. A turntable 5 is provided between the first mounting shell 3 and the second mounting shell 4. The center of the turntable 5 is provided with a through hole that matches the first mounting shell 3, and the outer wall of the turntable 5 is provided with annularly distributed toothed grooves 6. The tooth pitch of the toothed grooves 6 is uniform and is used to transmit rotational power. As attached Figure 1 Appendix Figure 2 Appendix Figure 4As shown, several angle-adjustable guide vanes 7 are evenly arranged on the outer side of the second mounting shell 4 along the circumferential direction. The number can be adjusted according to the diameter of the guide pipe 1 and the air volume requirements. Each guide vane 7 is an arc-shaped plate structure, and its curvature is adapted to the curvature of the inner wall of the connecting ring 2 to ensure that the airflow can flow smoothly along the surface of the guide vane 7. The end of each guide vane 7 near the second mounting shell 4 is rotatably connected to the second mounting shell 4 through a rotating shaft. The axis of the rotating shaft is consistent with the radial direction of the second mounting shell 4. The end of each guide vane 7 away from the second mounting shell 4 is respectively welded and fixed with a limiting shaft 9. The limiting shaft 9 is a cylindrical structure, and its axis is collinear with the axis of rotation of the guide vane 7. The inner wall of the connecting ring 2 is provided with an annular limiting groove adapted to the limiting shaft 9. The end of the limiting shaft 9 away from the guide vane 7 is embedded in the annular limiting groove and rotatably connected to the annular limiting groove. Through the cooperation of the limiting shaft 9 and the annular limiting groove, the rotation trajectory of the guide vane 7 is restricted, and the guide vane 7 is prevented from deviating or falling off under the impact of airflow. As attached Figure 4 As shown, the inner wall of the second mounting shell 4 is provided with a number of gears 8 corresponding to the positions of each guide vane 7. Each gear 8 is rotatably connected to the second mounting shell 4 through a bearing, and one end of each gear 8 passes through the side wall of the second mounting shell 4 and extends to the shaft of the guide vane 7, where it is welded and fixed to the shaft of the guide vane 7. The tooth surface of each gear 8 meshes with the tooth groove 6 on the outer wall of the turntable 5. When the turntable 5 rotates around the axis of the first mounting shell 3, the tooth groove 6 can drive all gears 8 to rotate synchronously, thereby driving each guide vane 7 to rotate around its own shaft, so as to realize the synchronous adjustment of the angle of all guide vanes. As attached Figure 1 Appendix Figure 4 As shown, a protective cover 10 is provided on the side of the second mounting shell 4 away from the first mounting shell 3. The protective cover 10 is shaped like a frustum and is made of stainless steel with anti-corrosion treatment. It can effectively block dust and debris from entering the control component and prevent the airflow from forming eddies at the end of the second mounting shell 4. A motor 11 is fixedly installed in the middle of the protective cover 10. The motor 11 is a servo motor, and its output shaft is set along the axis of the protective cover 10. The output end of the motor 11 passes through the small diameter end of the protective cover 10 and the end of the second mounting shell 4 and extends to the center of the turntable 5, and is fixedly connected to the turntable 5 by a coupling. The motor 11 can drive the turntable 5 to rotate clockwise or counterclockwise by forward and reverse rotation, thereby controlling the angle adjustment direction of the guide vanes 7.
[0015] The specific working principle is as follows: connect the power supply and control circuit of motor 11, and connect the motor 11 to the main controller of the air shower system, such as a PLC controller. The main controller can automatically control the forward and reverse rotation angle of motor 11 according to the signal from the temperature sensor output by the air conditioner.
[0016] When the air conditioner outputs cold air at a low temperature, such as below 15℃, the temperature sensor transmits a signal to the main controller, which then controls motor 11 to rotate forward. The output shaft of motor 11 drives turntable 5 to rotate clockwise, and the tooth grooves 6 on the outer wall of turntable 5 synchronously drive each gear 8 to rotate counterclockwise. Gear 8 drives the guide vanes 7 to rotate counterclockwise around their own axis, causing each guide vane 7 to gradually tilt towards the axis of the connecting ring 2, such as the radial angle between the guide vane 7 and the connecting ring 2 decreasing from 30° to 10°. After the tilt angle of the guide vane 7 is reduced, the air conditioning airflow is concentrated near the axis of the connecting ring 2, forming a concentrated airflow bundle, which avoids excessive diffusion of cold air and causes the local temperature in the air shower area to be too low; at the same time, the concentrated airflow bundle can enhance the blowing force on the surface of the goods, improve the dust removal effect, and prevent condensation from appearing on the surface of electronic components due to low temperature.
[0017] When the air conditioner outputs hot air, such as at a temperature higher than 28°C, the temperature sensor transmits a signal to the main controller, which then controls motor 11 to reverse. The output shaft of motor 11 drives turntable 5 to rotate counterclockwise, and the tooth grooves 6 on the outer wall of turntable 5 synchronously drive each gear 8 to rotate clockwise. Gear 8 drives the guide vanes 7 to rotate clockwise around their own axis, causing each guide vane 7 to gradually tilt toward the inner wall of the connecting ring 2, such as the radial angle between the guide vane 7 and the connecting ring 2 increasing from 10° to 30°. After the tilt angle of the guide vane 7 increases, the air conditioning airflow is dispersed to the entire circumference of the connecting ring 2, forming a uniform diffused airflow. This avoids excessive hot air concentration, which can cause the local temperature in the air shower area to be too high. At the same time, the diffused airflow can cover a larger area of the goods surface, ensuring that all parts of the goods are heated evenly and preventing food goods from spoiling or losing moisture due to local high temperatures.
[0018] When the air conditioner outputs ambient air at a temperature between 15-28℃, the main controller controls the motor 11 to stop running, and the guide vane 7 remains at its initial angle, such as a radial angle of 20° with the connecting ring 2. At this time, the airflow is in a moderately diffused state, which can meet the airflow intensity requirements of the air shower dust removal and ensure the temperature and humidity stability of the air shower area.
[0019] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
