Description

Technical Field

[0001] This utility model relates to the field of airflow utilization, and in particular to an automatic pressure relief and adjustment mechanism for upper air supply. Background Technology

[0002] If large quantities of organic materials such as duck manure or chicken manure from the livestock industry are discarded into the environment, they will cause significant pollution. Currently, these organic materials are often transformed into bio-fertilizers through biological fermentation, turning waste into treasure. Biological fermentation is mostly carried out in fermentation tanks.

[0003] When organic materials ferment in a fermentation tank, they generate a lot of heat, which heats the air inside the fermentation tank, resulting in a lot of air with a high temperature inside the fermentation tank.

[0004] In order to effectively reuse the high-temperature air in the fermentation tank, the air in the fermentation tank is often extracted and sent out. However, in actual delivery, it has been found that the pressure or temperature in the delivery pipeline is too high, which can damage the delivery pipeline and exceed the allowable value of subsequent processing equipment, posing certain safety hazards.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The present invention provides an automatic pressure relief regulating mechanism for upper air supply, comprising an upper air intake mechanism 1, an air supply mechanism 2, an air outlet pipe 3, a fan 4, a temperature sensor 5, an air pressure sensor 6, a pressure relief valve 7, and a controller.

[0022] The upper air intake mechanism 1 includes an air intake pipe 11 and an insert 12. The bottom end of the air intake pipe 11 is provided with a first extension 111, and the top end of the insert 12 is provided with a second extension 121. The bottom of the first extension 111 and the bottom of the second extension 121 abut against each other and are fixedly connected by multiple screws, so that the air intake pipe 11 and the insert 12 are fixedly connected. Both the air intake pipe 11 and the insert 12 are hollow and are connected to each other.

[0023] The fan 4 is provided with an air inlet 41 and an air outlet 42. The other end of the air inlet pipe 11 of the upper air inlet mechanism 1 is connected to the air inlet 41 of the fan 4 through a connecting pipe. The air outlet pipe 3 is connected to the air outlet 42 of the fan 4 through a connecting pipe.

[0024] The pressure relief valve 7 is preferably an electric pressure relief valve. The pressure relief valve 7 is fixedly installed on the pipe body of the air outlet pipe 3 by screws, and the pressure relief valve 7 is connected to the inside of the air outlet pipe 3. The pressure relief valve 7 is also connected to the atmosphere. Under normal conditions, the pressure relief valve 7 is closed, and the pressure relief valve 7 isolates the air outlet pipe 3 from the atmosphere. However, when the pressure relief valve 7 is opened, the air outlet pipe 3 can be connected to the atmosphere through the pressure relief valve 7.

[0025] The air supply mechanism 2 includes a first air outlet pipe 21 and a second air outlet pipe 22. The air outlet pipe 3, the first air outlet pipe 21 and the second air outlet pipe 22 are connected in sequence and in communication. The temperature sensor 5 is fixedly installed on the pipe body of the first air outlet pipe 21 by screws, and the temperature sensor 5 extends into the first air outlet pipe 21. The air pressure sensor 6 is installed on the pipe body of the second air outlet pipe 22 by screws, and the air pressure sensor 6 extends into the second air outlet pipe 22.

[0026] Temperature sensor 5 and pressure sensor 6 are electrically connected to the controller via wires. The controller is also electrically connected to pressure relief valve 7 via wires. The controller can control the opening and closing of pressure relief valve 7.

[0027] The air supply mechanism 2 also includes a manual valve 23. The first air outlet pipe 21 and the second air outlet pipe 22 are connected by the manual valve 23, and the user can manually operate the manual valve 23 to disconnect the connection between the first air outlet pipe 21 and the second air outlet pipe 22.

[0028] The air supply mechanism 2 also includes a first connecting plate 24, a second connecting plate 25, and connecting bolts 26. The first connecting plate 24 is fixedly sleeved on the first air outlet pipe 21 by welding, and the second connecting plate 25 is fixedly sleeved on the second air outlet pipe 22 by welding. There are multiple connecting bolts 26, and the first connecting plate 24 and the second connecting plate 25 are connected by multiple connecting bolts 26 to improve the connection reliability of the first air outlet pipe 21 and the second air outlet pipe 22.

[0029] The automatic pressure relief adjustment mechanism for the upper air supply also includes a bracket 8. The body of the fan 4 is fixedly mounted on the bracket 8 with screws.

[0030] The upper air supply automatic pressure relief adjustment mechanism also includes a support block 9 and a surrounding block 10. The second air outlet pipe 22 of the air supply mechanism 2 abuts against the support block 9, while the surrounding block 10 is fixedly connected to the support block 9 by a nut, and the surrounding block 10 is wrapped around the second air outlet pipe 22 of the air supply mechanism 2, so that the second air outlet pipe 22 can be fixed on the support block 9, and the support block 9 can support the second air outlet pipe 22.

[0031] During installation, the bracket 8 can be fixedly installed on the top of the fermenter by screws, and the support block 9 can also be fixedly installed on the top of the fermenter by screws. The height of the support block 9 can be adapted to the height of the bracket 8 so that the first air outlet pipe 21 and the second air outlet pipe 22 can be set perpendicular to the horizontal plane.

[0032] The insert 12 of the upper air intake mechanism 1 can be embedded into the top of the fermentation tank and fixedly connected to the fermentation tank by screws. At this time, the insert 12 can be connected to the top area inside the fermentation tank, and the second air outlet pipe 22 of the air supply mechanism 2 can be connected to the heat exchanger and other hot air treatment equipment. The pressure relief valve 7 and the manual valve 23 are normally closed.

[0033] During operation, the hot air generated during the fermentation of organic materials in the fermentation tank can rise to the top of the fermentation tank. When the blower 4 is started, the blower 4 can draw the hot air out of the fermentation tank. The hot air can be input into the blower 4 through the insert 12 and the air inlet pipe 11 in sequence, and then output to the hot air treatment equipment for processing after passing through the air outlet pipe 3, the first air outlet pipe 21 and the second air outlet pipe 22 in sequence, so as to realize the reuse of hot air.

[0034] During the hot air delivery process, temperature sensor 5 senses the temperature of the hot air passing through air delivery mechanism 2, and air pressure sensor 6 senses the air pressure of the hot air passing through air delivery mechanism 2, transmitting the corresponding values ​​to the controller. When the temperature sensed by temperature sensor 5 or the air pressure sensed by air pressure sensor 6 exceeds the expected value, the controller drives pressure relief valve 7 to open, connecting air outlet pipe 3 to the atmosphere. Hot air can then be discharged through air outlet pipe 3, effectively reducing the amount of hot air continuing to be delivered to air delivery mechanism 2. Once the temperature and air pressure sensed at air delivery mechanism 2 meet the requirements, the controller drives pressure relief valve 7 to close, and hot air delivery resumes normal operation.

[0035] Therefore, the automatic pressure relief regulating mechanism of the upper air supply can effectively prevent the temperature or pressure of the hot air input to the air supply mechanism 2 from being too high, which could damage the subsequent hot air treatment equipment and effectively ensure safety.

[0036] In addition, when the user needs to urgently cut off the hot air input to the subsequent hot air handling equipment, the manual valve 23 can be manually closed to cut off the connection between the first air outlet pipe 21 and the second air outlet pipe 22.

[0037] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
