Abstract
Description
Technical Field
[0001] The utility model belongs to the field of beer brewing auxiliary equipment, and in particular relates to an air filtering device. Background Art
[0002] In the beer brewing process, people usually pay much attention to the aseptic treatment of production equipment. Therefore, whether it is the production of raw materials or the process of pumping oxygen for yeast fermentation, aseptic operations are generally carried out, and the air used is filtered. However, in the production workshop, dust will inevitably be generated in the process of adding raw materials, or some external dust will be brought into the workshop during the entry and exit of personnel, causing dust pollution in the workshop environment. Although the pollution of this type of dust to the production raw materials will be minimal, the dust in the working environment will still have a certain degree of impact on the staff there. Utility Model Content
[0003] In order to solve the above technical problems, the utility model provides an air filtering device, by setting a base of the filtering device, inserting filter cotton into the upper cavity of the suction cavity therein, and the switching plate covering the suction cavity can realize two different suction air flow rates by covering / opening the upper cavity, thereby realizing slow / fast air filtering effect, and the filter cotton can be easily replaced after the filtering is completed, thereby realizing air filtering of the internal environment of the workshop.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0005] An air filter device comprises an inhalation assembly, a filter assembly and a bracket, wherein the inhalation assembly comprises a base, an inhalation port and a switching plate, wherein an inhalation cavity is arranged in the base, the inhalation port is arranged at the side opening of the inhalation cavity, the inhalation cavity is divided into an upper cavity and a lower cavity by a horizontal partition plate, filter cotton is placed in the upper cavity, a plurality of through holes which pass through the upper and lower cavities are arranged on the partition plate, the switching plate is slidably connected to the opening of the inhalation cavity and reciprocally covers the upper cavity or the lower cavity, and when the switching plate covers the upper cavity, there is a gap between the upper end of the switching plate and the conversion head, so that the inhalation cavity is filled with a filter. A limit head and a limit plate are provided at the bottom of the switching plate. The limit head passes through from the outside to the inside and can be movably connected to the switching plate. The end of the limit head is connected to the limit plate. A accommodating hole is provided on the partition plate, and the accommodating hole cooperates with the limit plate; the filter assembly includes a conversion head, an elbow and a blower. The lower end of the conversion head is connected to the upper end opening of the suction chamber. The lower end surface of the conversion head is provided with a plurality of filter holes connected to the inner cavity. One end of the elbow is connected to the conversion head, and the other end of the elbow is provided with a flange connected to the blower; the bracket is detachably connected to the base.
[0006] The air filter device adopts this structure, and a suction chamber for air to flow into is provided on the base body, and a bracket is detachably connected to the outside of the base body, and the bracket can be installed at any position in the workshop to realize air filtering at that position; a suction port for convenient air introduction is provided at the side opening of the suction chamber, and a conversion head is covered at the upper end of the suction chamber, and the filter holes at the lower end of the conversion head are respectively connected to the suction chamber and the inner cavity of the conversion head, and an elbow is connected to the upper end of the conversion head, and the end of the elbow is connected to the blower through a flange. During the operation of the blower, air enters the suction chamber from the suction port, and enters the conversion head through the filter holes at the upper end of the suction chamber, and finally the air is sucked out by the blower after passing through the elbow. In order to realize the filtering function, filter cotton can be placed in the suction chamber, and the air is blocked by the filter cotton when entering the suction chamber, so that the dust in the air can be adsorbed in the filter cotton to complete the filtration. However, this method will cause the effective distance between the filter cotton in the suction chamber and the filter holes on the conversion head to be short, so the air can only be filtered on the filter cotton at the connection between them.
[0007] Therefore, a partition plate is provided in the suction chamber to divide the suction chamber into an upper chamber and a lower chamber, and a switching plate which can movably cover the upper chamber and the lower chamber respectively is covered at the opening of the suction chamber. After the filter cotton is placed in the upper chamber, the switching plate is pushed upward to cover the upper chamber. At this time, since a number of through holes are provided on the switching plate, after the blower is started, the air will first pass through the lower chamber. After passing through the through holes, the air needs to pass through the entire filter cotton before entering the inner chamber of the conversion head. Therefore, after separating the upper and lower chambers, the effective filtering distance of the filter cotton can be extended. However, this method has a disadvantage. If the filter cotton is full of dust and blocks the air flow, and the blower continues to operate but cannot suck in air, it may easily cause the blower to burn out. Therefore, after the switching plate covers the upper cavity, a gap is reserved between the upper end of the switching plate and the conversion head. The gap is very short to the filter hole. Once a large amount of dust has accumulated on the filter cotton, resulting in poor air flow, some air can still enter the filter hole at the gap, avoiding the possibility of the blower burning out. Moreover, the total opening area of the gap is smaller than the through hole. Under normal operation, most of the air will still enter the through hole.
[0008] When the limiter is pulled outward by a hand, the limiter plate is pulled and abutted against the inner side surface of the switch plate. At this time, the switch plate can be pulled downward. After the limiter plate passes through the accommodating hole, the switch plate can be moved to cover the opening of the lower chamber. At this time, it is convenient to replace the filter cotton in the upper chamber. At the same time, the upper chamber that is opened can directly enter the filter cotton at the opening of the upper chamber, and then filter the air through the filter hole. Compared with covering the upper chamber and allowing the air to enter the filter cotton from the through hole for filtration, the flow rate will be much faster, thereby achieving two air filtration effects with different flow rates.
[0009] Furthermore, the filter assembly also includes a gas flow sensor. The conversion head is provided with a mounting hole, and the gas flow sensor is connected to the mounting hole.
[0010] Compared with the prior art, the utility model has the advantages that: by dividing the suction chamber into an upper chamber and a lower chamber, filter cotton is placed in the upper chamber, when the switching plate covers the upper chamber, air enters from the lower chamber and is slowly filtered through the filter cotton, and when the switching plate covers the lower chamber, the switching plate blocks the lower chamber, so that air enters from the opening of the upper chamber into the filter cotton for rapid filtration. The air filtering device can realize air filtration at different positions in the workshop by installing a bracket. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Furthermore, the filter assembly 2 also includes a gas flow sensor 23 . The conversion head 21 is provided with a mounting hole 212 , and the gas flow sensor 23 is connected to the mounting hole 212 .
[0022] Description of the working method of this utility model:
[0023] The air filter device adopts this structure, and a suction chamber 111 for air to flow into is provided on the base 11, and a bracket 3 is detachably connected to the outside of the base 11, and the bracket 3 can be installed at any position of the workshop to achieve air filtering at that position. The side opening of the suction chamber 111 is provided with a suction port 12 for conveniently introducing air, and a conversion head 21 is covered at the upper end of the suction chamber 111, and the filter holes 211 at the lower end of the conversion head 21 are connected to the inner cavity of the suction chamber 111 and the conversion head 21 respectively, and the upper end of the conversion head 21 is connected to an elbow 22, and the end of the elbow 22 is connected to the blower through a flange 221, and when the blower is running During the process, air enters the suction chamber 111 from the suction port 12, passes through the filter hole 211 at the upper end of the suction chamber 111, and enters the conversion head 21. Finally, the air is sucked out by the blower after passing through the elbow 22. In order to achieve the filtering function, filter cotton can be placed in the suction chamber 111. The air is blocked by the filter cotton when entering the suction chamber 111, and the dust in the air can be adsorbed in the filter cotton to complete the filtration. However, this method will cause the effective distance between the filter cotton in the suction chamber 111 and the filter hole 211 on the conversion head 21 to be short, and the air can only be filtered on the filter cotton at the connection between them.
[0024] Therefore, a partition plate 114 is provided in the suction chamber 111 to divide the suction chamber 111 into an upper chamber 112 and a lower chamber 113, and a switch plate 13 is provided at the opening of the suction chamber 111 to cover the upper chamber 112 and the lower chamber 113 respectively. After the filter cotton is placed in the upper chamber 112, the switch plate 13 is pushed upward to cover the upper chamber 112. At this time, since a plurality of through holes 115 are provided on the switch plate 13, after the blower is started, the air will first pass through the lower chamber 113. After passing through the through holes 115, the air needs to pass through the entire filter cotton before entering the inner cavity of the conversion head 21. Therefore, after the upper and lower chambers 113 are separated, the effective filtering distance of the filter cotton can be extended. However, This method has a disadvantage. If the filter cotton is full of dust and blocks the air flow, and the blower continues to operate but cannot suck in air, it may easily cause the blower to burn out. Therefore, after the switching plate 13 covers the upper chamber 112, a gap 131 is reserved between the upper end of the switching plate 13 and the conversion head 21. The distance between the gap 131 and the filter hole 211 is very short. Once the filter cotton has accumulated a lot of dust and the air flow is not smooth, some air can still enter the filter hole 211 at the gap 131, avoiding the possibility of the blower burning out. Moreover, the total opening area of the gap 131 is smaller than the through hole 115. Under normal operation, most of the air will still enter the through hole 115.
[0025] In order to enable the switch plate 13 to remain closed at the opening of the upper chamber 112, a limit head 132 that can be movably connected to the switch plate 13 is provided at the bottom of the switch plate 13, and the lower end of the limit head 132 abuts against the top of the partition plate 114, and the switch plate 13 is supported on the upper end of the partition plate 114 by the limit head 132. In order to switch the switch plate 13 to cover the lower chamber 113, a receiving hole 116 is provided on the partition plate 114, and the receiving hole 116 cooperates with the limit plate 133 connected to the end of the limit head 132. When the limit head 132 is pulled outward by hand, the limit plate 133 is pulled and abuts against the inner side surface of the switch plate 13. At this time, the switch plate 13 can be pulled downward. After the limit plate 133 passes through the receiving hole 116, the switch plate 13 can be moved to the cover By closing the opening of the lower chamber 113, the filter cotton in the upper chamber 112 can be conveniently replaced. At the same time, the upper chamber 112 is opened, and the air can directly enter the filter cotton at the opening of the upper chamber 112, and then pass through the filter hole 211 for air filtering. Compared with covering the upper chamber 112 to allow the air to enter the filter cotton from the through hole 115 for filtration, the flow rate will be much faster, thereby achieving two air filtration effects with different flow rates. In order to prevent the filter cotton from accumulating too much dust and causing the blower to burn out while idling, a gas flow sensor 23 is set in the mounting hole 212 of the conversion head 21. By detecting the air flow passing through the conversion head 21, when the flow is reduced, the filter cotton can be replaced in advance, thereby extending the service life of the air filter device.
[0026] The beneficial effect of the utility model is that by dividing the suction chamber 111 into an upper chamber 112 and a lower chamber 113, filter cotton is placed in the upper chamber 112, and when the switching plate 13 covers the upper chamber 112, air enters from the lower chamber 113 and is slowly filtered through the filter cotton; when the switching plate 13 covers the lower chamber 113, the switching plate 13 blocks the lower chamber 113, so that air enters from the opening of the upper chamber 112 into the filter cotton for rapid filtration. The air filtering device can realize air filtration at different positions in the workshop by installing the bracket 3.

Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some or all of the technical features therein with equivalents.
