Description

Technical Field

[0001] The invention relates to the technical field of air filtering equipment, in particular to an air intake purification device for a duck food processing workshop. Background Art

[0002] During duck meat processing, air quality in the workshop plays a crucial role in the quality and safety of duck products. Unclean air can carry pollutants such as dust, bacteria, and viruses. Once these pollutants adhere to the duck meat or processing equipment, they can easily lead to microbial growth, causing the duck meat to spoil, affecting product quality, and even endangering consumer health.

[0003] Existing air purification devices have shortcomings in terms of purification efficiency, effectiveness, and adaptability to air with varying degrees of pollution. Some devices can only filter large dust particles and are ineffective in removing tiny bacteria and viruses.

DETAILED DESCRIPTION

[0032] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0033] As a specific embodiment of the present invention, the air intake purification device for a duck meat food processing workshop recorded mainly includes filter devices for filtering particulate impurities, pathogens and odors in the air. These filter devices include a filter component 1 for filtering large particulate impurities in the air, and an ionization component 2, an electrostatic adsorption component 3, an ultraviolet sterilization component 4, an activated carbon adsorption component 5, and a fresh air mixing component 6 connected in sequence to the air outlet end of the filter component 1. The ionization component 2 is composed of high-voltage electrodes, which can partially ionize the air flowing through and charge the tiny particles in the air. Specifically, the ionization component 2 is an ionization module and can be arranged after the above-mentioned filter component 1 as an air preliminary filtration function module. The ionization component 2 can be composed of several high-voltage electrodes, and its function is to partially ionize the air that has passed the primary filtration, so that the tiny particles in the air are charged, which is convenient for subsequent collection and removal. In this embodiment, the electrostatic adsorption component 3 is designed to include multiple electrode plates 205. Under the action of an electric field, the electrode plates 205 can adsorb charged microparticles in the passing air. In specific manufacturing, multiple electrode plates 205 can be included to work in conjunction with the ionization component 2. Under the action of the electric field, the electrode plates 205 can adsorb charged microparticles, further removing pollutants such as dust and pollen from the air, with a purification efficiency of over 95%. The ultraviolet sterilization component 4 uses an ultraviolet lamp to fully irradiate the passing air, killing microorganisms in the air. For example, a high-intensity ultraviolet lamp is used to fully irradiate the air after electrostatic adsorption. Ultraviolet rays can destroy the DNA structure of bacteria and viruses, effectively killing microorganisms in the air, with a sterilization rate of over 99%. The activated carbon adsorption component in this embodiment includes activated carbon filled in the adsorption pipe to adsorb the residual odor and harmful gases in the air passing through. The activated carbon adsorption component utilizes the porous structure of the activated carbon to adsorb the residual odor and harmful gases (such as formaldehyde, benzene, etc.) in the air, ensuring that the air entering the workshop is fresh and odorless. Figure 1As shown, the fresh air mixing assembly 6 in this embodiment includes a fresh air output pipe 601, a return air pipe 602, an outlet pipe 603, a suction pump, a solenoid valve, and a temperature and humidity sensor. One end of the fresh air output pipe 601 is connected to the outlet of the adsorption pipe, and the other end thereof is connected to the inlet of the outlet pipe 603 together with the return air pipe 602, and the inlet of the return air pipe 602 is located inside the processing workshop; the temperature and humidity sensor is also installed in the processing workshop, and the solenoid valve adjusts its opening and closing degree according to the detection value of the temperature and humidity sensor so that the temperature and humidity of the air output from the air pipe 603 are within a set range compared with the temperature and humidity maintained in the processing workshop. In specific implementation, the purified air can be mixed with part of the return air in the workshop, and by adjusting the return air ratio, the temperature and humidity of the air entering the workshop can be made more suitable for the environmental requirements of duck food processing. At the same time, this embodiment is also specially equipped with a temperature and humidity sensor, which can monitor the temperature and humidity parameters of the air in real time and feedback to the corresponding control system for precise adjustment. In the above embodiments, as for the control system, it specifically refers to the responsibility for monitoring and adjusting the operation of the entire air intake purification device. It can automatically adjust the working parameters of the aforementioned components according to the feedback information of the above-mentioned temperature and humidity sensors configured in the workshop, as well as the adaptively selected air quality sensors, such as the voltage of the ionization component 2, the irradiation time of ultraviolet sterilization, the return air ratio of the fresh air mixing component 6, etc., to ensure that the purification effect is always in the best state.

[0034] In the above embodiment, a filter assembly 1 can be optionally installed at the inlet of the return air duct 602 to filter out some impurities generated in the workshop before mixing the original air in the duck food processing workshop with the fresh air. Figure 2 As shown, the electrostatic adsorption component 3 also includes an insulating cylinder 201, a carrying ring 206, an end face gear ring 207, a cylindrical gear 202, a screw 203, and a conductive shell 204. Specifically, the insulating cylinder 201 itself is insulated, and the wind tunnel diameters at both ends are much smaller than the cylinder diameter itself, so that when the air flows through, it can more fully contact the internal electrode plate 205. In more detail, the cylindrical gear 202 is mounted on the tooth end face of the end face gear ring 207 in a meshing transmission manner, and the end face gear ring 207 is rotatably mounted on the end face of a carrying ring 206 fixed to the outside of the insulating cylinder 201. It should be noted that the end face gear ring 207 here is a hollow end face gear, which is different from the commonly seen circular gears. Its gear teeth are arranged on the end face, and the rotating shafts of the two gears that mesh with each other are not parallel, but can mesh with gears that are perpendicular to their axes. In this embodiment, as Figure 2 and Figure 7As shown, the cylindrical gear 202 is made from a shorter shaft blank, with the gear teeth on its surface extending to one end face of the shaft, and the other end being a smooth shaft section. A sleeve 210 is coaxially mounted on the smooth shaft section. This sleeve 210 serves as a mounting bearing for the cylindrical gear 202 and is fixedly mounted via a connecting crank arm 213 to support and mount the rotatable cylindrical gear 202. Figure 7 The cylindrical gear 202 is coaxially sleeved with the screw rod 203, that is, the end of the screw rod 203 without a thread is axially slidably installed in the shaft hole 20201 of the cylindrical gear 202, and is slidably connected to the sliding key 211 fixed on the inner wall of the shaft hole 20201 through the sliding key groove 212, so that when the cylindrical gear 202 rotates in place, it not only penetrates the wall of the insulating tube 201 with the screw rod 203 threadedly, but also allows the screw rod 203 to be fed axially. An arc-shaped conductive shell 204 is fixed to one end of the lead screw 203 located inside the insulating tube 201. Inside the conductive shell 204, there are several electrode plates 205. All of the above-mentioned cylindrical gears 202 are engaged with the end face gear ring 207 in a ring array to achieve synchronous movement of all electrode plates 205 to adjust the ionization effect. When all the electrode plates 205 are closer to each other, the air flow in the axial direction of the wind tunnel will be slower, but the contact time with the electrode plates 205 will be longer, and the ionization will be more complete.

[0035] In this embodiment, Figure 2-Figure 3 As shown, a central plate located on the symmetry axis is installed on the inner wall of each conductive shell 204, and a number of side plates are symmetrically installed on both sides of the central plate to more fully contact with the air flowing through. Figure 2 A micro motor 208 is also fixed to the outer arm of the insulating cylinder 201. A transmission gear 209 driven by the micro motor 208 is engaged with the end face gear ring 207 to drive all cylindrical gears 202 to rotate synchronously, and then adjust the positions of all electrode plates 205.

[0036] In this embodiment, Figure 4-Figure 5As shown, the filter assembly 1 includes a filter pipe 101 and a filter plate assembly 103. The filter plate assembly 103 slides axially and horizontally within the filter chamber 102 of the filter pipe 101. A slide groove is linearly provided on the lower side wall of the filter chamber 102. A slide beam 105 on the bottom side of the filter plate assembly 103 slides in cooperation with the slide groove to achieve sliding installation of the filter plate assembly 103. A slide hole 104 is specifically provided on the upper side wall of the filter chamber 102, facing away from the air inlet, for the filter plate assembly 103 to fall. The filter plate assembly 103 falls through the slide hole 104 and then slides down into the filter chamber 102 in an upright state so as to be transferred by the driving block 109 mentioned later and then overlapped on several existing filter plate assemblies 103 to improve filtering performance. In addition, in this embodiment, a sliding bin is provided below the chute, and a driving block 109 is provided in the sliding bin for horizontal movement. The driving block 109 can drive the filter plate assemblies 103 that slide down into the filter bin 102 one by one to the end of the filter bin 102 near the inlet and place them in an overlapping manner. For example, Figure 4 The filter plate assembly 103 on the far left is translated onto a plurality of filter plate assemblies 103 stacked on the right side for combination, thereby increasing the filtering level.

[0037] In the above embodiment, the slide beam 105 is made of a viscomagnetic material and can be attracted by the drive block 109 and move with it in a specific position. Specifically, a plurality of mounting slots are arranged horizontally at intervals at the bottom of the chute. Each mounting slot is supported by a return spring 108 and connected to a slider 106 that protrudes from the bottom of the chute. This slider 106 is a cubic structure, and the edge of the top of the slider 106 facing the outlet of the filter chamber 102 is processed into a rounded corner 107.

[0038] When making specific Figure 5 As shown, the driving block 109 includes a mounting base 10901, and a first magnet 10903 and a second magnet 10902 mounted in the mounting base 10901 one after the other. The first magnet 10903 is closer to the air inlet side of the filter chamber 102. That is, if the first magnet 10903 is closer to the air inlet side of the filter chamber 102, the first magnet 10903 is closer to the air inlet side of the filter chamber 102. Figure 4In the figure, the first magnet 10903 is on the right, and the second magnet 10902 is on the left. Both magnets must each move below the slider 106 to completely draw the slider 106 into the mounting slot. That is, both the first magnet 10903 and the second magnet 10902 can only fully draw the slider 106 into the mounting slot when they move to near the bottom of the slider 106, or to the bottom of the mounting slot, allowing the corresponding filter plate assembly 103 to slide freely and unimpeded. In practice, as one feasible and recommended design, the slider 106 can be completely retracted when the first magnet 10903 is about to move directly below the slider 106, while the slider 106 can only be completely retracted when the second magnet 10902 moves exactly to the bottom of the slider 106. In addition, the first magnet 10903 needs to move to the bottom of the sliding beam 105 in order to move with the sliding beam 105. When it is close to the bottom of the sliding beam 105, it is not enough to drive the sliding beam 105 or the filter plate assembly 103.

[0039] In this embodiment, when the driving block 109 moves with the filter plate assembly 103 toward the air inlet side of the filter chamber 102, the sliding beam 105 can start to press the slider 106 from the rounded corner 107, that is, press the slider 106 into the installation groove, so that the filter plate assembly 103 can move forward normally. However, when the driving block 109 moves in the opposite direction to the stacked final filter plate assembly 103, for example, when it moves to the left, Figure 4-Figure 5 When the filter plate assembly 103 is in the position shown, the first magnet (10903) completely absorbs the corresponding slider 106 into the installation slot to move the final filter plate assembly 103 toward the air outlet of the filter chamber 102. However, at this time, the slider 106 closest to the left cannot be retracted into the installation slot where it is located; the driving block 109 and the filter plate assembly 103 continue to move left, and when the left side of the slide beam 105 is in contact with the filter plate assembly 103, the first magnet (10903) completely absorbs the corresponding slider 106 into the installation slot to move the final filter plate assembly 103 toward the air outlet of the filter chamber 102. Figure 5 When the top side wall of the leftmost slider 106 contacts the second magnet 10902, the second magnet 10902 moves to the bottom of the slider 106, thereby completely sucking the slider 106 into the installation slot. Then the driving block 109 continues to move left, and the filter plate assembly 103 attracted by it continues to move to the left, and continues to retreat to the left. Similarly, it can slide over a series of sliders 106 until it moves to the left to the limit, open the above-mentioned sliding hole 104, and take out the filter plate assembly 103, thereby reducing the number of filter plate assemblies 103 and reducing the number of filtration stages. On the contrary, the number of filter plate assemblies 103 can be increased and the filtration stage can be improved. In addition, there is another key purpose, which is to facilitate daily maintenance and cleaning. The filter plate assemblies 103 can be taken out one by one for cleaning to avoid clogging of the filter plate assemblies 103 due to long-term use.

[0040] In this embodiment, Figure 4As shown, the slide bin is a rectangular cavity, which can be a relatively shallow cavity, and the first magnet 10903 and the second magnet 10902 are both bar magnets parallel to the slide beam 105. However, as shown in FIG. Figure 6 As shown, the first magnet 10903 here specifically includes three magnets connected by an insulating rod 1090301. The magnet in the middle is the same as the first magnet 10903 and is horizontally opposite to each other, so that the first magnet 10903 and the second magnet 10902 each need to move to the bottom of the slider 106 before they can be completely sucked into the mounting groove. The purpose of this design is, first, to prevent the second magnet 10902 from magnetically moving back to the left and the corresponding filter plate assembly 103 from being directly moved by the second magnet 10902. Three magnets are required to drive the filter plate assembly 103 to move; second, to prevent the driving block 109 from completely sucking in the slider 106 before it moves to the bottom of the slider 106 when it moves to the left. Therefore, a relatively independent magnet with the same size as the second magnet 10902 is designed to mainly achieve the function of attracting the slider 106, and to try to avoid the influence of the attraction of the other two magnets. In practice, as shown in FIG. Figure 4 In theory, it is possible to directly design the first magnet 10903 and the second magnet 10902 to be of different sizes. However, in actual production, it is more difficult to grasp the range of the size difference between them. In other words, it is not easy to intuitively grasp the difference in magnetic magnitude, and it is difficult to determine how far the first magnet 10903 can move forward to contact the top sidewall of the other slider 106 when it is attracted to the corresponding slider 106. This can easily lead to the filter plate assembly 103 driven by the slider 106 being blocked when the driving block 109 moves leftward or the second magnet 10902 has already attracted the slider 106 at the bottom of the final filter plate assembly 103 before the driving block 109 moves to the final filter plate assembly 103, causing the driving block 109 to mistakenly move both filter plate assemblies to the left at once. As for the matching structure of the above-mentioned slider 106, a rectangular cross-section socket 10501 can be provided along the length of the bottom of the slide beam 105 to match the design of the slider 106 when it adopts a bar structure. As for the elastic telescopic installation of the slider 106, Figure 5 The cross section of this mounting groove is rectangular, and several return springs 108 are evenly spaced along its length. A cover plate 112 is horizontally slidably installed at the upper end of the sliding hole 104. The cover plate 112 is connected to the electric telescopic rod 113 to achieve complete exposure and closure of the sliding hole 104.

[0041] In this embodiment, Figure 4-Figure 5As shown, the drive block 109 is threadedly mounted on a screw 111 through a threaded sleeve 110. The screw 111 is rotatably installed in the sliding bin near the bottom of the bin. The screw 111 is connected to the main shaft of the drive motor (not shown in the figure) to move the drive block 109 back and forth horizontally in the sliding bin, thereby realizing the transportation when the filter plate assembly 103 is increased or decreased.

[0042] Based on the above embodiments, another embodiment will be described in detail regarding an air purification method for a duck meat food processing workshop. This method also primarily utilizes the aforementioned air purification device for duck meat food processing workshops to purify the air. In actual operation, air pretreatment is first performed. External air first enters filter assembly 1. As a preliminary filtration step, the filter material within filter assembly 1, for example, is filtered through a metal mesh to intercept and filter out large impurities, thereby initially purifying the air. Pre-ionization is then performed. The pre-filtered air enters ionization assembly 2. High-voltage electrodes within ionization assembly 2 ionize the air, charging the fine particles. The airflow is then fed into electrostatic adsorption assembly 3 for electrostatic adsorption purification. Specifically, the charged air enters electrostatic adsorption assembly 3. Under the action of the corresponding electric field, the charged particles are adsorbed onto the charged electrode plate 205, achieving further purification. Subsequently, ultraviolet disinfection is performed. The air, which has undergone electrostatic adsorption, enters ultraviolet disinfection assembly 4, where it is irradiated with high-intensity ultraviolet light to fully kill bacteria and viruses. After the above process, the air is deodorized by activated carbon adsorption, and then enters the activated carbon adsorption component to remove residual odors and harmful gases. The air that comes out of the activated carbon adsorption component can be called fresh air, that is, clean air. However, considering the stability of the existing set environment in the duck meat food processing workshop, it is also necessary to use a fresh air mixing and adjustment component to mix and reform the new and old air. The purified clean external air and the air in the workshop that is kept within the set temperature and humidity range (herein referred to as return air) are mixed in the fresh air mixing component 6 in an appropriate proportion. After adjusting the temperature and humidity of the air, it is finally output to the workshop. During the entire purification process, in order to achieve the greatest extent of automated control, the purification process of the incoming air can be monitored and adjusted in real time. The control system is designed in a targeted manner.
