Description

Technical Field

[0001] This utility model relates to the field of air treatment technology, specifically to a particulate matter collection device for ventilation openings in livestock sheds. Background Technology

[0002] Modern livestock sheds are typically equipped with ventilation systems to maintain air circulation. When these sheds exhaust air, feed dust and dried manure particles are expelled into the atmosphere, significantly impacting nearby residents. To address this, some farms install sprinkler systems at the exhaust vents to spray water mist into the exhaust air and remove dust particles. However, this method consumes a large amount of water and can easily cause secondary pollution. Utility Model Content

[0003] To address the aforementioned issues, this application provides a particulate matter collection device for ventilation openings in livestock sheds, which removes dust through sedimentation, thereby reducing costs.

[0004] The purpose of this utility model is achieved through the following technical solution: a particulate matter collection device for a livestock shed ventilation opening, comprising a collection chamber connected to the livestock shed ventilation opening and an exhaust pipe connected to the collection chamber and extending vertically upward; the top of the collection chamber is provided with multiple baffles spaced apart from one side of the livestock shed ventilation opening to the other side, so that the particulate matter entering the collection chamber from the livestock shed ventilation opening falls to the bottom of the collection chamber by natural settling.

[0005] This invention collects particulate matter discharged from the ventilation openings of the breeding shed into a collection chamber. The particulate matter settles naturally to the bottom of the collection chamber. Compared with water mist spraying, it can save water resources and avoid secondary pollution of sewage.

[0006] The exhaust duct extends upwards by 10-15 meters, which makes it difficult for particulate matter in the collection room to be discharged from the exhaust duct, and also allows the gas discharged from the breeding house to be sent to a higher position, away from the living area on the ground, thus reducing the impact on the living area.

[0007] The length of the baffle extending downwards gradually increases from one side of the ventilation opening in the breeding house to the other side, which can block the flowing particles and allow the particles to settle better.

[0008] The bottom of the collection chamber, away from the ventilation opening of the breeding house, is equipped with a collection trough. The collection chamber is equipped with a cleaning mechanism for cleaning the particles that have settled to the bottom of the collection chamber into the collection trough.

[0009] This invention facilitates the cleaning of particulate matter by collecting it in a collection tank within the collection chamber.

[0010] The cleaning mechanism includes two slide rails respectively installed on the two inner walls of the collection chamber, a shaft with both ends installed in the two slide rails, and a scraper installed on the shaft; the shaft can move along the slide rails, and the lower end of the scraper is in close contact with the bottom of the collection chamber, forming an acute angle of 30-60° with the bottom of the collection chamber.

[0011] During cleaning, simply push the scraper forward to remove particles that have settled at the bottom of the collection chamber into the collection trough. It is simple and convenient to use.

[0012] The collection room has a door located on the side closest to the breeding shed.

[0013] The collection tank is equipped with a gate at its end.

[0014] Compared with the prior art, this application has the following beneficial effects: the present invention collects the particulate matter discharged from the breeding house by natural settling to the bottom of the collection room, which saves water resources compared with water mist spraying.

[0015] Some of the additional features of this application will be described in the following description. These additional features will become apparent to those skilled in the art upon examination of the following description and the accompanying drawings, or upon understanding the production or operation of the embodiments. The features disclosed in this application can be implemented and achieved through the practice or use of various methods, means, and combinations thereof with respect to the specific embodiments described below.

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments.

[0021] Example

[0022] like Figure 1 As shown in the figure, this embodiment discloses a particulate matter collection device for aquaculture shed ventilation openings, including a collection chamber 2 connected to aquaculture shed ventilation opening 4 and an exhaust pipe 5 connected to the collection chamber 2 and extending vertically upward.

[0023] Specifically, the exhaust pipe 5 is located at the end of the collection chamber 2 away from the ventilation opening 4 of the breeding house, and the exhaust pipe 5 extends upward 10-15 meters. In this embodiment, the height of the exhaust pipe 5 is set to 15 meters, so that the particulate matter in the collection chamber 2 is not easily discharged from the exhaust pipe 5, and the gas discharged from the breeding house 1 can be sent to a higher position through the exhaust pipe 5, thereby away from the living area on the ground and reducing the impact on the living area.

[0024] In addition, multiple baffles 3 are spaced apart on the top of the collection chamber 2 from one side of the vent 4 of the breeding house to the other side, and the length of the baffles 3 extending downwards gradually increases from one side of the vent 4 of the breeding house to the other side. When the air in the breeding house 1 carrying particulate matter enters the collection chamber 2 from the vent 4 of the breeding house, it is blocked by the baffles 3, and the particulate matter falls to the bottom of the collection chamber 2 by natural sedimentation.

[0025] In specific setup, the space inside the collection chamber 2 should be relatively large to create normal pressure and reduce airflow velocity. This facilitates the settling of particulate matter and makes it less likely for particulate matter to be discharged from the exhaust duct 5. Alternatively, a filter screen can be installed at the lower end of the exhaust duct 5 to further prevent particulate matter from being discharged. During use, the filter screen can be cleaned periodically.

[0026] In this embodiment, the particulate matter discharged from the ventilation opening 4 of the breeding house is collected in the collection chamber 2. The particulate matter falls to the bottom of the collection chamber 2 by natural sedimentation. Compared with water mist spraying, it can save water resources and avoid secondary pollution of sewage.

[0027] A collection trough 10 is provided at the bottom of the collection chamber 2 on the side away from the ventilation opening 4 of the breeding house. A cleaning mechanism is provided in the collection chamber 2 to clean the particles that have settled to the bottom of the collection chamber 2 into the collection trough 10.

[0028] like Figure 1 , 2As shown, the cleaning mechanism includes two slide rails 6 respectively mounted on opposite inner walls of the collection chamber 2, a shaft 9 with both ends installed within the two slide rails 6, and a scraper 8 mounted on the shaft 9. The shaft 9 can move along the slide rails 6, so when the shaft 9 is pushed along the slide rails 6, the scraper 8 can also move accordingly. The width of the scraper 8 matches the width of the collection chamber 2, and its lower end is in close contact with the bottom of the collection chamber 2, forming an acute angle of 30-60° with the bottom of the collection chamber 2. In this embodiment, the acute angle formed between the scraper 8 and the bottom of the collection chamber 2 is set to 45°. Specifically, the scraper 8 can be made of rubber, and its lower end is inclined towards the collection trough 10. When the shaft 9 is pushed towards the collection trough 10, the scraper 8 cleans the particles settled at the bottom of the collection chamber 2 into the collection trough 10, making it simple and convenient to use. Shaft 9 can rotate. When scraper 8 is returned to the side of the vent 4 in the breeding shed, shaft 9 can be rotated to separate scraper 8 from the bottom of collection chamber 2. During the cleaning process, scraper 8 adheres tightly to the bottom of collection chamber 2 under the action of gravity. After cleaning, scraper 8 needs to be returned to the side of the vent 4 in the breeding shed. At this time, because the upper end of scraper 8 is close to the wall of collection chamber, the settled particles are not easy to fall into the triangular space enclosed by scraper 8, collection chamber wall and bottom of collection chamber.

[0029] In specific setup, a brush can be installed at the opening of the slide rail 6 to reduce the probability of particles entering the slide rail. A door 7 is installed in the collection chamber 2 near the breeding shed 1, allowing staff to enter the collection chamber to clean the particles. By placing the door 7 on the side of the collection chamber 2 near the breeding shed 1, staff can easily operate the cleaning mechanism without having to cross it after entering the collection chamber.

[0030] The end of the collection tank 10 is provided with a tank door 11. After opening the tank door 11 from the outside of the collection chamber, the particulate matter collected in the collection tank 10 can be cleaned.

[0031] It should be noted that all features disclosed in this specification, or all steps in all methods or processes disclosed, may be combined in any way, except for mutually exclusive features and / or steps.

[0032] Furthermore, the specific embodiments described above are exemplary. Those skilled in the art can devise various solutions inspired by the disclosure of this utility model, and these solutions all fall within the scope of this utility model and its protection. Those skilled in the art should understand that this utility model specification and its drawings are illustrative and not intended to limit the scope of the claims. The scope of protection of this utility model is defined by the claims and their equivalents.
